The shape of through holes of piece is corresponding with the cross sectional shape at the card slot for crossing cloth beam.
The beneficial effects of the utility model are:
1. the both ends that the utility model crosses cloth beam are provided with friction mechanism and regulating mechanism, increase frictional resistance to avoid
Overshoot adjusts two side-friction force sizes using adjusting nut to guarantee that cloth beam excessively is same with colour band and scroll cloth in print procedure
When step movement, colour band and scroll cloth stop, crossing cloth beam and stop immediately, will not continue to rotate;Both it had avoided and had been generated because of friction
A large amount of electrostatic, also to print again when enough tensile forces are provided, improve the safety and reliability of printing device.
The cloth beam outer surface of crossing of the utility model is provided with rubber layer, and rubber layer outer surface is frosting, and inside it
For hollow structure, the frictional force between cloth beam and colour band and scroll cloth was increased, and reduced the rotary inertia of cloth beam itself,
Further ensured that cloth beam was moved synchronously with colour band and scroll cloth.
The bearing block of the utility model is equipped with positioning ring, and bearing block is located on vertical plate by positioning ring, and positioning is quasi-
Really, it is ensured that cloth beam both ends excessively are concentric, make have enough contacts area between cloth beam and colour band and scroll cloth, and avoid because of contact surface
Product is insufficient and reduces frictional force and causes friction slip.

Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing.
As shown in Fig. 1 ~ Fig. 5, a kind of used cloth structure of printing device, crossing cloth structure includes for connecting with printing device
Two vertical plates 2 and cloth beam 1 is crossed between two vertical plates 2, cloth beam 1 and the vertical plate 2 crossed is rotatablely connected, described to cross cloth beam 1
Both ends are provided with friction mechanism, are provided with regulating mechanism on the outside of the friction mechanism, 2 outside screw of vertical plate is fixed with bearing
Seat 3, the both ends of the cloth beam 1 excessively pass through the bearing block 3 and vertical plate 2, are provided with bearing between bearing block 3 and excessively cloth beam 1, institute
Stating friction mechanism includes the inner attrition piece 4 for being fixed at 3 outside of bearing block and the outside friction disc for being laid in 4 outside of inner attrition piece
5, the outside friction disc 5 was correspondingly arranged on cloth beam 1, and outside friction disc 5 slides axially along cloth beam 1 excessively and rotates with cloth beam 1 is crossed,
The inner attrition piece 4 and outside friction disc 5 are bonded to each other, and the inner attrition piece 4 is wafer body made of wear-resisting flexible material, this reality
Applying inner attrition piece 4 in example is wafer body made of plastics, and the outside friction disc 5 is wafer body made of abrasion-resistive hard material, this
Outside friction disc 5 is wafer body made of stainless steel in embodiment, and the regulating mechanism includes the spring for being linked in 1 end of cloth beam
6 and adjusting nut 7, described 6 one end of spring is supported to outside friction disc 5, the other end and is supported to adjusting nut 7, the adjusting nut 7 and mistake
Cloth beam 1 is threadedly coupled.
In order to optimize product structure, in the present embodiment, described cross is hollow structure inside cloth beam 1, crosses 1 outer surface of cloth beam and sets
It is equipped with rubber layer, the rubber layer outer surface is frosting, the frictional force between cloth beam 1 and colour band and scroll cloth was increased, and
And reduced the rotary inertia of cloth beam 1 itself, further ensured that cloth beam 1 was moved synchronously with colour band and scroll cloth.
In order to enable bearing block 3 fast, accurately to install, positioning ring 8, institute are provided on 3 inner side end of bearing block
It is annular in shape and be integrally formed with bearing block 3 to state positioning ring 8, bearing block 3 is correspondingly arranged at the outside of vertical plate 2 by positioning ring 8.
It is described to cross 1 both ends axial direction cloth of cloth beam in order to make outside friction disc 5 slide axially along cloth beam 1 excessively and be rotated with cloth beam 1 is crossed
Equipped with card slot, the middle part of outside friction disc 5 offers through-hole, the shape of through holes of outside friction disc 5 and the section at the card slot for crossing cloth beam 1
Shape is corresponding.
When printing, adjusting nut 7 is set to change in the position crossed on cloth beam 1 by rotating adjusting nut 7, and then adjust
