Description

The invention relates to a tape bonding cutter, which is suitable for cutting the tape immediately after bonding.

At present, the commonly used sealing tape bonding cutter (as shown in Figure 1) is to connect the sleeve B with both ends of the opening on the frame A, for the sleeve film C, and pull out the end D of the tape , Stick to the guide shaft tube E and protrude to an appropriate length; when in use, hold the grip F with your hand, extend your fingers from both ends of the sleeve B to fasten it, and then stick the end D to the opening of the carton The end (not shown in the figure), you can pull the sealing tape adhesive cutter to move backwards along the opening, so that the tape is pulled out from the tape roll C and placed flat on the carton opening, while the roller G rolls over it, and The adhesive tape sticks tightly to the opening to close the opening of the carton, and the rear end of the adhesive tape is cut off with the serrated cutter H above the roller G to complete the sealing work. However, this cutter has been found to have some drawbacks in use:

1. The zigzag fixed cutter is fixed on the front end of the adhesive cutter, which is easy to stab human hands, and the cutting is not neat.

2. The adhesive surface D at the end of the tape is in contact with the guide shaft tube E, and the pasted tape passes through the guide shaft tube, which affects the sticking strength of the tape.

3. When the adhesive surface at the end D of the adhesive tape is not in use, it is easily polluted by dust and loses its original adhesiveness.

4. The sleeve B that fits the tape roll C and the tape roll C are too loose, and the tape roll C can be reversed freely or fall off.

In view of this, the purpose of the present invention is to provide a closed sealing tape adhesive cutter, so that the adhesive tape is in the closed shell, the cutting knife is in a safe position, and the contact area between the guide and the adhesive surface of the adhesive tape is reduced. , not only to ensure the bonding strength but also to make the operation safe.

The object of the present invention is achieved in this way: it includes a shell frame, a cutter device, a tape guide plate and a tape sleeve; wherein the shell frame is composed of a base frame and a cover plate, the front part of the base frame is arc-shaped, and the upper wall has a cut The button of the knife device exposes a hole, and there is a gap under the shell frame where the front and rear rolling cylinders protrude partially. The inner edges of the two side walls are provided with chute, pivot and hanger. The front part is divided, there is a guide plate in the gap at the lower part, a hollow short cylindrical structure seat with a tape sleeve in the center of the rear side wall, and three elastic clasps on the barrel; the cutter device is composed of a blade, a blade seat, a knife holder, a button and tension springs, and placed between the two side walls of the front part of the base frame, wherein the blade is above the gap between the front and rear rolling cylinders, and the blade has a tapered edge with a width greater than that of the tape, and the upper part is fixed In the blade combining groove at the lower part of the blade seat, the blade seat is a flat open sleeve with a card hole on the upper part, the knife holder is U-shaped, and there are fitting pieces on both sides to slide into the slides on the inner edges of the two sides of the front part of the shell frame. In the groove, there are buckles on both sides of the upper end of the tool holder to be inserted into the button holes on both sides of the button. On the rod, the tape guide plate is set behind the front gap of the base frame, and is in the shape of an arc sheet, and its upper edge has a flange; the tape sleeve is a hollow cylinder, which is connected perpendicular to the inner edge of the above-mentioned cover plate. The snapping hole of the protruding elastic strip.

Due to the above scheme, the operation is safe, the adhesive tape loss is reduced, the tape is not easily polluted by dust, and the tape roll will not loosen or fall off.

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

In the embodiment shown in Figures 2-7:

The shell frame 1 is composed of a base frame 5 and a cover plate 6 . Wherein the front part of the base frame 5 is an arc-shaped shell, and the button 7 of the cutter device 2 is exposed on the upper wall to expose the hole 8, so that the finger touches the button 7, and the bottom of the shell frame 1 is provided with a front and rear rolling cylinder 9, 10. Partially protruding gap 11, the inner edges of the two side walls 12, 13 are provided with two slide grooves 17, 18 for positioning the tool holder 14 (as shown in Figure 7), the pivot 15 of the pivot button 7 and the spring suspension rod 16 , for connecting the cutter device 2. The rear part of the base frame 5 is separated from the front part by a partition plate 18, and there is a guide plate 3 behind the gap 11 below, and the joint seat 19 of the tape sleeve 4 is provided in the center of the rear side wall, and the joint seat 19 is a hollow short cylinder , There are three elastic clasps 20 on the barrel, which can be assembled into the engaging holes 22 of the seat tube 21, the seat tube 21 is on the inner side perpendicular to the cover plate 6, for the tape roll 23 to be set.
