The auxiliary roller 400 can be used to assist the cloth to pass between the upper roller 200 and the lower roller 300. At the same time, the support plate 500 is used to increase the support area of ​​the cloth, so that the cloth can flow more smoothly between the upper roller 200 and the lower roller 300.

[0040] See also Figure 2 and Figure 3In some embodiments, the fixed plate 100 is provided with a sliding groove 110 at the installation position of the first fixed shaft 210. The sliding groove 110 is vertically arranged. The first fixed shaft 210 can be lifted up and down by passing through the sliding groove 110. The fixed plate 100 is provided with a limit plate 120 at the top of the sliding groove 110. The limit plate 120 is L-shaped. The limit plate 120 fits the top of the fixed plate 100 and can be stably installed. The top of the limit plate 120 is connected to the fixed plate 100 by a first fastener 150. The first fastener 150 is a fastening bolt, which can effectively realize the fixed installation of the limit plate 120.

[0041] In some embodiments, a cam 230 is provided at a position of the first fixed shaft 210 near the fixed plate 100, a flat step 231 is provided on the circumferential side of the cam 230, and the remaining circumferential sides are circular side surfaces, a fixed block 130 is provided on the fixed plate 100 located above the cam 230, and a limiting block 140 is provided on the fixed plate 100 located below the cam 230, when the flat step 231 is in contact with the fixed block 130, there is a gap between the upper roller 200 and the lower roller 300; when the flat step 231 is separated from the fixed block 130, the upper roller 200 and the lower roller 300 are in contact with each other.

[0042] Specifically, when the flat step 231 of the cam 230 abuts against the fixed block 130, there is a gap between the upper roller 200 and the lower roller 300, and the gap is used to facilitate the fabric to be passed between the upper roller 200 and the lower roller 300. When the fabric is passed, the first fixed shaft 210 is rotated, and the first fixed shaft 210 drives the cam 230 to rotate, so that the flat step 231 on the cam 230 is separated from the fixed block 130, and the remaining circular side surfaces are respectively abutted against the fixed block 130 and the limit block 140. When part of the circular side surfaces abut against the fixed block 13 0, at this time, the cam 230 drives the first fixed shaft 210 to slide down along the sliding groove 110, and the round side surfaces of the cam 230 respectively abut against the fixed block 130 and the limit block 140. At this time, the first fixed shaft 210 is firmly limited in the sliding groove 110, and the first fixed shaft 210 drives the first roller 220 to move down synchronously while sliding down to achieve the fit with the lower roller 300. At this time, the cloth is clamped between the upper roller 200 and the lower roller 300. When the lower roller 300 rotates, the cloth is conveyed, and the first roller 220 rotates synchronously.

[0043] In some embodiments, the fixing block 130 is straight, so that the flat step 231 on the cam 230 is fitted, so that when the flat step 231 of the cam 230 is fitted to the fixing block 130, the first fixing shaft 210 does not rotate, so that the cloth can be better passed between the upper roller 200 and the lower roller 300. The left and right sides of the fixing block 130 are connected to the fixing plate 100 by the second fastener 160, and the second fastener 160 is a fastening bolt. By using the second fastener 160, the fixing block 130 can be effectively fixed and installed.

[0044] In some embodiments, the limit block 140 is parallel to the fixed block 130, so that the round side surface of the cam 230 can abut against the fixed block 130 and the limit block 140 at the same time. The left and right sides of the limit block 140 are connected to the fixed plate 100 through the third fastener 170. The third fastener 170 is a fastening bolt. Through the third fastener 170, the fixed installation of the limit block 140 can be effectively achieved.

[0045] In some embodiments, an anti-slip groove 141 is provided on the side of the limit block 140 facing the cam 230. The anti-slip groove 141 can be made of silicone material. By utilizing the set anti-slip groove 141, the cam 230 will not become loose when it abuts against the limit block 140, and the first fixed shaft 210 can be firmly fixed in the sliding groove 110. At the same time, the anti-slip groove 141 is made of silicone material. When the cam 230 abuts against the limit block 140, the friction between the two is greater and the anti-fixing effect is better.

[0046] In some embodiments, a joystick 240 is provided at one end of the first fixed shaft 210, and the joystick 240 is vertically connected to the first fixed shaft 210. The joystick 240 is used to facilitate the control of the rotation of the first fixed shaft 210, which saves effort and has good control flexibility.

[0047] See also Figure 4 , a driving assembly 600 is arranged on one side of a fixed plate 100 away from the joystick 240, and the driving assembly 600 comprises a motor 610, a first gear 620, a second gear 630 and a conveyor belt 640. The motor 610 is fixedly mounted on the fixed plate 100, and a pulley 611 is arranged at the end thereof. When the motor 610 rotates, the pulley 611 is driven to rotate. The first gear 620 is connected to one end of the lower roller 300, the second gear 630 is connected to one end of the auxiliary roller 400, and the conveyor belt 640 is connected to the pulley 611, the first gear 620 and the second gear 630 in sequence. When the motor 610 rotates, the pulley 611 rotates simultaneously. When the pulley 611 rotates, the conveyor belt 640 can be used to control the rotation of the first gear 620 and the second gear 630 respectively. When the first gear 620 rotates, the lower roller 300 can be driven to rotate, and when the second gear 630 rotates, the auxiliary roller 400 can be driven to rotate. With this structure, the cloth can be smoothly controlled to be transported forward.

[0048] The implementation principle of the embodiment of the present application is as follows: when the flat step 231 of the cam 230 abuts against the fixed block 130, there is a gap between the upper roller 200 and the lower roller 300, and the gap is used to facilitate the fabric to be passed between the upper roller 200 and the lower roller 300. When the fabric is passed, the first fixed shaft 210 is rotated, and the first fixed shaft 210 drives the cam 230 to rotate, so that the flat step 231 on the cam 230 is separated from the fixed block 130, and the remaining circular side surfaces are respectively abutted against the fixed block 130 and the limit block 140. When part of the circular side surfaces abut against the fixed block 130, the cam 230 drives the first fixed shaft 210 to rotate. 210 slides down along the sliding groove 110, and the round side surfaces of the cam 230 respectively abut against the fixed block 130 and the limit block 140. At this time, the first fixed shaft 210 is firmly limited in the sliding groove 110. When the first fixed shaft 210 slides down, it drives the first roller 220 to move down synchronously to achieve the fit with the lower roller 300. At this time, the cloth is clamped between the upper roller 200 and the lower roller 300. When the lower roller 300 rotates, the cloth is conveyed, and the first roller 220 rotates synchronously. By using this structure, the distance between the upper roller 200 and the lower roller 300 can be quickly adjusted to achieve efficient control of material threading and feeding.

[0049] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
