[0012] By adopting the above technical solution, the personnel first clamp the two ends of the cloth head along the width direction on the two clamping parts respectively, and then start the driving motor, which drives the first driving gear to rotate. Since the first driving gear is engaged with the driving rack, the first driving gear drives the driving rod to move, and the two clamping parts on the driving rod pass the cloth through the box to complete the cloth threading. The driving component has a simple and reasonable structure. The driving component and the drive component jointly complete the loading. There is no need for staff to enter the box to load the materials, which further reduces the contact between staff and the solution inside the box.

[0016] By adopting the above technical solution, the staff will overcome the elastic force of the torsion spring and rotate the first clamping plate, move the first clamping plate away from the second clamping plate, and then place the cloth between the first clamping plate and the second clamping plate. The staff will loosen the first clamping plate, and the first clamping plate will approach the second clamping plate under the action of the torsion spring.

The plurality of anti-slip strips correspond one-to-one to the plurality of anti-slip grooves, and the anti-slip grooves are used to accommodate the anti-slip strips.

[0018] By adopting the above technical solution, the anti-slip groove on the first clamping plate and the anti-slip strip on the second clamping plate cooperate with each other, thereby increasing the contact area between the fabric and the first clamping plate and the second clamping plate, and further increasing the friction between the fabric and the first clamping plate and the second clamping plate, thereby improving the effect of the clamping member in clamping the fabric.

[0019] Optionally, the driving assembly is also provided with an adjusting member for driving the two clamping members to move closer to or away from each other, and the adjusting member includes a bidirectional screw, a worm gear, a worm and a turning handle. The length direction of the bidirectional screw is parallel to the length direction of the driving rod, and the bidirectional screw is rotatably connected to the driving rod.

The worm gear is coaxially arranged with the bidirectional screw, and the worm gear is arranged on the bidirectional screw. The worm is rotatably connected to the driving rod, the worm is engaged with the worm gear, and the turning handle is arranged on the worm.

[0020] By adopting the above technical solution, due to the different widths of the fabrics, it is necessary to adjust the distance between the two clamping parts to facilitate clamping of overly narrow fabrics; the staff rotates the handle, the handle drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the bidirectional screw to rotate, and the bidirectional screw drives the two first clamping plates to move closer to or away from each other along the length direction of the driving rod until the distance between the two first clamping plates is suitable for clamping the two ends of the fabric head along the width direction.

[0024] By adopting the above technical solution, the moving direction of the driving frame is different from the moving direction of the first rotating roller, and the first sliding block needs to be slidably connected to the box body. Due to the existence of the driving rack, the first sliding block cannot slide over a long distance, and the driving rack is divided into multiple sections, and the first sliding block is placed outside the box body, so that the structure of the driving component and the driving component is more reasonable, and the interference between the driving component and the driving component is reduced; due to the distance between the multiple rack sections, the first driving gear and the second driving gear keep rotating in the same direction under the action of the idler gear, and the distance between the first driving gear and the second driving gear is greater than the distance between the rack sections, which ensures that the first driving gear and the second driving gear can always drive the driving rod to move. Since the first sliding groove passes through the box body, the box body cannot be sealed, and the solution is easy to flow out of the first sliding groove. The mounting cover covers the several first sliding grooves, and the interior of the mounting cover is connected to the interior of the box through the first sliding groove.

[0058] The implementation principle of a flat-width alkali reducer with convenient loading in the embodiment of the present application is as follows: the staff starts the driving motor 53, and the driving motor 53 drives the first driving gear 54 and the second driving gear 57 to rotate. The first driving gear 54 and the second driving gear 57 drive the driving rod 51 to move toward the cloth inlet under the engagement of the rack segment 521 until the driving rod 51 abuts against the first control switch 47. The first control switch 47 drives the output shaft of the driving motor 44 to rotate, and the output shaft of the driving motor 44 drives the driving gear 43 to rotate. The driving gear 43 drives the first driving rack 42 and the second driving rack 46 to move, and the first transmission group 2 and the second transmission group 3 move until the height of the first transmission group 2 is lower than the height of the second transmission group 3.

[0059] The staff adjusts the distance between the two clamping members 55 according to the width of the fabric. The staff turns the gripping handle, and the turning handle 564 drives the worm 563 to rotate, and the worm 563 drives the worm gear 562 to rotate, and the worm gear 562 drives the bidirectional screw 561 to rotate, and the bidirectional screw 561 drives the two clamping members 55 to a distance corresponding to the width of the fabric. Then the staff pushes the dial plate 554, and moves the second clamping plate 552 away from the first clamping plate 551 to overcome the elastic force of the torsion spring 553, and places the fabric between the first clamping plate 551 and the second clamping plate 552, and releases the dial plate 554. The second clamping plate 552 approaches the first clamping plate 551 under the action of the elastic force of the torsion spring 553 and clamps the fabric. Under the action of the anti-slip strip 556 and the anti-slip groove 555, it is more difficult for the fabric to separate from the clamping member 55.

[0060] The staff starts the driving motor 53 again, and the driving motor 53 drives the first driving gear 54 and the second driving gear 57 to rotate, and the driving rod 51 moves to the cloth outlet of the box body 1 until the driving rod 51 abuts the second control switch 48.

The first transmission group 2 and the second transmission group 3 are staggered and away from each other. Driven by the first transmission group 2 and the second transmission group 3, the cloth is distributed in a broken line shape in the box body 1 and is tightened in the box body 1. At this time, the first conveying gear 63 of the first transmission group 2 is meshed with the synchronous belt 61, and the second conveying gear 65 of the second transmission group 3 is meshed with the conveying idler wheel 66. The conveying motor 64 drives the synchronous belt 61 to rotate, and the synchronous belt 61 drives the first transmission roller 22 and the second transmission roller 32 to rotate at the same time, driving the cloth to move from the cloth inlet end toward the cloth outlet end.
