[0002] At present, the slurry tank part of the filament sizing machine is equipped with a rubber dipping roller. The silk is immersed in the slurry through the roller surface and then squeezed by the slurry pressing roller to achieve the sizing effect. There is a rectangular stainless steel hanging plate and a casting hanging arm on each side of the rubber dipping roller. The hanging plate and the hanging arm have two upper and lower holes. An optical axis passes through the upper hole, and the lower hole is for the shaft head of the dipping roller. The two ends of the optical axis are placed on two casting seats, and the casting seats are lifted up and down by the rack shaft, thereby achieving the effect of lifting the dipping roller up and down.

When in use and when stationary, the rack and gear wear greatly. After using for a period of time, the wear on both sides is prone to be inconsistent, resulting in the dipping roller rising and lowering being out of sync, with one side higher and the other side lower. In severe cases, there is no way to achieve lifting and lowering.

[0037] When in use, by using 3-mode 22 gears and cylindrical side racks 17, the contact area is increased by 50% to about 200 square millimeters, which greatly increases the load capacity and service life. By starting the drive motor 10, the output end of the drive motor 10 will drive the active gear 9 to rotate, and through the chain transmission, it will drive the driven gear 11 to rotate, and then drive the rotating rod 7 to rotate, thereby driving the spur gear 19 to rotate, and through the meshing connection between the spur gear 19 and the side rack 17, the lifting column 4 is moved, and then the immersion roller body 1 is driven to lift and lower. The upper limit plate at the upper end of the lifting column 4 and the adjustment plate 15 at the lower end can provide guidance and support for the lifting column 4, thereby improving the stability of the lifting column 4.

[0038] Embodiment 3

[0039] On the basis of the second embodiment, the lifting column 4 and the adjustment plate 15 are slidably connected, a plurality of limit holes 16 are provided, and the plurality of limit holes 16 are evenly distributed on the surface of the lifting column 4, and two groups of adjustment plates 15 are provided, and the inner frame 13 is fixed between the two groups of adjustment plates 15 by bolts; the limit rod 25 passes through the inner frame 13, and the end surface of the limit rod 25 is chamfered, and the limit rod 25 can be inserted into the limit hole 16;

[0041] When in use, when the slurry dipping roller body 1 is stationary, the auxiliary support of the lifting column 4 can be achieved by inserting the limit rod 25 into the limit hole 16. The specific operation is as follows: when supplementation is needed, the spring 24 is always in a stretched state. When the limit rod 25 is not inserted into the limit hole 16, the first stop block 21 is located in the short stop groove 26, the second stop block is located in the long stop groove 27, and the first stop block 21 is in contact with the bottom wall of the short stop groove 26.

The end surface of the limiting rod 25 is chamfered to improve the smoothness and accuracy of the limiting rod 25 when it is inserted into the limiting hole 16.

[0043] In actual use, on the one hand, the present solution modifies the gear module and enlarges the teeth of the rack shaft, so that the meshing area between the gear and the rack is large, and the commonly used 2-module 32-tooth spur gear 19 (contact area of ​​about 130 square millimeters) is replaced with a 3-module 22-tooth gear (contact area increased by 50% to about 200 square millimeters), and at the same time cooperates with the side rack 17 opened on the lifting column 4, which greatly increases the load capacity and service life. On the other hand, by opening a limiting hole 16 on the surface of the lifting column 4, and inserting a limiting plug 25 into the limiting hole 16, the limiting plug 25 is used to assist in supporting the lifting column 4, so as to relieve the pressure of the weight of the slurry dipping roller on the rack and the gear, and by setting the special-shaped cylinder 14 and the disc 23 , spring 24, rotating drum 20 and pull ring 6, can facilitate the adjustment of the position of the limit rod 25, thereby greatly reducing the probability of damage to the machine during production, reducing maintenance costs, and increasing production efficiency. This avoids the problem in the prior art that the pulping machine's pulping roller lifting uses a 2-mode 32-tooth spur gear and a cylindrical side rack to form a turbine worm structure, which has a small contact area (about 130 square millimeters) and a small area of ​​tooth-to-tooth engagement, resulting in small force and a heavy weight of the pulping roller. When in use and when stationary, the rack and gear wear greatly. After a period of use, the wear on both sides is prone to be inconsistent, resulting in the pulping roller lifting being out of sync, with one side higher and the other side lower. In severe cases, there is even no way to achieve the lifting problem.
