Description

A composite machine for preparing hot-melt adhesive wall covering

technical field

The invention relates to a compound production equipment of fabric and hot-melt omentum, in particular to a back glue compound machine of hot-melt adhesive wall cloth.

Background technique

With the improvement of environmental protection requirements, solvent-free hot melt adhesive materials are more and more accepted and applied in the field of fabric lamination. As important products of hot-melt adhesive materials, hot-melt adhesive film and hot-melt omentum are more popular in the market because of their convenience in application. At present, the general method of compounding with hot-melt adhesive film or hot-melt omentum and fabric is to transport the face cloth fabric and hot-melt adhesive film or hot-melt omentum material to the heating zone simultaneously for heating and pressurizing compounding. However, due to the hot-adhesive properties of hot-melt adhesive products after heating, when the surface cloth and hot-melt adhesive film or hot-melt omentum are combined separately (we call it two-in-one), hot-melt adhesive film or hot-melt adhesive film will appear. When one side of the omentum is bonded to the fabric, the other side will be bonded to the mechanical parts. For solving it, the existing equipment design adopts the anti-adhesive conductive tape with Teflon or the band release paper to isolate. In actual production, the hot-melt adhesive film and the hot-melt omentum are also adhesive when they are in contact with the hot Teflon conductive tape. Therefore, on the one hand, in order to melt the omentum to generate adhesive force, the Teflon tape is heated; process. In this way, not only the length of the Teflon conduction tape is lengthened, but also the contradiction between heating and cooling at the same time limits the production speed and wastes energy. Coupled with the constraints of the joint of the guide belt, the width of the guide belt, and the deviation of the guide belt, the production speed and product quality are greatly affected. If release paper is used for isolation, the problem of bonding parts is solved, but it increases the cost and increases the difficulty of operation, especially for hot-melt omentum products without release paper base, it is a waste and Environmentally unfriendly production methods.

For the production of wide-width hot-melt adhesive wall coverings, due to the particularity of the properties of the hot-melt adhesive film or hot-melt omentum used, as well as the equipment technical bottleneck caused by the wide-width Teflon conductive tape, there is currently no 1.6-meter The release paper with a wider width needs to be spliced, which makes the above phenomenon more serious.

detailed description

The technical solution of the present invention is: the surface cloth as a decorative fabric passes through the unwinding and correcting device and the front operating platform, and is covered by the opening roller after being flattened by the opening roller, which is heated to the set temperature by feeding heat transfer oil in advance. The surfaces of the first preheating roller and the second preheating roller preheat the face cloth to a certain temperature. Then, through the contraction of the bracket action cylinder, the bracket rotates counterclockwise around the bracket rotation axis, forming the bracket to tilt towards the second preheating roller, so that the omentum reel and omentum roll placed on the bracket are under gravity , roll along the inclined direction of the carriage until the omentum roll on the omentum roll shaft leans against the second preheating roller whose surface is covered with face cloth. Under the action of the friction force and thermal adhesive force of the surface cloth wrapped on the surface of the second preheating roller, the omentum reel is driven to rotate, and the automatic unwinding of the omentum roll is realized, and the omentum is pre-coated on the surface evenly. cloth surface. With the operation of the second preheating roller, the face cloth and the web pre-composite product are transported to the pressurized zone formed by the cooling roller and the second preheating roller pressurized by the pressurized cylinder for pressure lamination to form hot-melt bonding sex wall covering. The finished wall covering passes through the rear operating platform and enters the winding system for winding.

In the present invention, the face cloth is firstly heated by a preheating roller, and then through the temperature conduction of the face cloth, the omentum covering the face cloth is gradually melted and then pressurized and compounded.

The omentum reel of the present invention is placed on the bracket, and the bracket can rotate clockwise and counterclockwise around the bracket shaft with the action of the cylinder acting on the bracket, so that the omentum roll that is sleeved on the omentum reel can be combined with the second preset Hot rollers make contact and separation. In the abnormal production state, the carriage action cylinder is in the extended state, and the web is separated from the second preheating roller. During normal production, the moving cylinder of the bracket is in a shrinking state, so that the omentum roll is in direct contact with the surface cloth wrapped on the surface of the second preheating roller, and the smooth unwinding of the omentum is realized. The advantage of unwinding in direct contact with the face cloth is that the omentum and the face cloth can be conveyed at zero distance, which avoids the tension shrinkage and wrinkling problems that occur during the long-distance conveyance of the tension-sensitive omentum.

The cooling roll of the present invention is fed with cooling water for forced cooling, so as to solve the temperature rise caused by the heat conduction of the cooling roll by the second preheating roll during continuous production, resulting in the phenomenon of omentum sticking to the pressure roll. In order to enhance the anti-adhesion effect, the cooling roller can also be treated by surface treatment, which includes: mirror treatment, Teflon coating, and silica gel coating.

The present invention considers that the wall surface is rough and uneven during the construction of the wall covering. In order to make the wall covering and the wall covering more firmly bonded, the surface of the cooling roller can be roughened or engraved with texture, concave points, convex points or other patterns. Make the glued surface of the hot-adhesive wall covering produced have a certain roughness, so as to ensure that the hot-melt glue can penetrate into the wall more firmly during hot lamination and increase the bonding fastness.

Below, the present invention will be further described with specific implementations through the accompanying drawings of the embodiments.

As shown in FIG. 1 , the unwinding and deviation correcting system 1 unwinds and corrects the deviation of the face cloth 2 , passes through the front operating platform 3 , and wraps it on the opening roller 5 . After the surface cloth 2 is opened by the opening roller 5, the wrinkles are removed, and then it is further wrapped on the first preheating roller 6 and the second preheating roller 7, which run at a certain speed and are preheated to the set temperature by heat transfer oil. The surface is heated, and the first preheating roller 6 and the second preheating roller 7 are driven by the main transmission system 15 and run in opposite directions. When the heated face cloth 2 is conveyed to the pressurized area formed by the second preheating roller 7 and the cooling roller 13, the bracket action cylinder 12 in the extended state shrinks, and the bracket 10 is driven counterclockwise around the bracket rotation axis 11. Rotate, the inclination of carriage 10 to the direction of second preheating roller 7, shelve on the carriage 10 away from the omentum reel 8 of second preheating roller 7, under the action of gravity, roll along the inclined carriage 10 to the second Preheating roll 7, till the face cloth 2 on the web roll 9 that is enclosed within on the web reel 8 and the second preheating roll 7 surface contacts. The direction of the omentum roll 9 that is enclosed within on the omentum reel 8, leans against the face cloth 2 with the omentum roll 9 and can be unrolled direction as positive. The omentum roll 9 leans against the running one, wraps the surface of the second preheating roller 7 and is heated by the surface cloth 2, under the action of the friction force and the omentum thermal bonding force formed by preliminary heating, the omentum roll 8 is driven to rotate together , to realize the smooth unwinding of the omentum while pre-coating the surface of the heating face cloth 2, and then together with the operation of the second preheating roller 7, it is transported to the pressing area. Then, the pressurized air cylinder 14 stretches out, pushes the cooling roller 13 against the second preheating roller 7, and presses and composites the pre-composite body of the face cloth and the web to become a thermally adhesive wall cloth 18 . The heat-adhesive wall cloth 18 passes through the rear operating platform 16 and is taken up into a roll by the winding system 17 . The above-mentioned opening roll 5, the first preheating roll 6, the second preheating roll 7, the carriage rotating shaft 11, the carriage action cylinder 12, the cooling roll 13, the pressurizing cylinder 14, the main drive system 15 are installed on 4 on the rack wall plate.
