[0002] For chemical fiber products, people pay more attention to their weaving properties, breaking strength, pilling and other conditions, but not enough attention is paid to the drawing-in and box-threading conditions of chemical fiber products. The automatic drawing-in machine can greatly improve the production efficiency, change the original manual drawing-in method, and combine the drawing-in and box-threading stages into one process. The existing equipment production method is to cut and clamp the upper end of the yarn, and run a hook at the lower end in the track. Through reciprocating motion, the hook hooks the yarn and passes through the heald wire and the steel box to complete the drawing-in and box-threading project.

[0003] For example, patent application number CN202021770448.9 discloses a threading machine with horizontal position control operation, which fixes the position of the moving plate by setting a spring, thereby fixing threading plates of different sizes. However, this technical solution still has shortcomings, as follows:

[0040] The following is combined with Figure 1-5 The utility model is described in further detail.

[0041] Embodiment 1, refer to Figure 1-3 In order to solve the problem that the existing screw rod is exposed to the outside and is easily entangled with chemical fiber yarns, causing accidents in use, the utility model discloses a threading device for chemical fiber yarn production.

[0042] The device assembly 100 includes a device base 101, a steel wire plate 102 is arranged on the upper right side of the device base 101, and a wire threading plate 103 is arranged on the front side of the steel wire plate 102;

[0043] The anti-roll component 200 also includes a first threaded block 201, which is located below the threading plate 103. The interior of the first threaded block 201 is connected to a driving screw 202, which is connected through the first threaded block 201 to store the driving screw 202 to prevent it from being exposed to the outside world. The other side of the driving screw 202 is connected to a driving motor 206. The top of the first threaded block 201 is connected to a connecting block 203, and elastic brushes 205 are arranged on both sides of the connecting block 203. The grooves on both sides of the connecting block 203 are sealed by the elastic brushes 205 to prevent the chemical fiber from falling from the grooves. The outer side of the elastic brush 205 is connected to a fixed block 204.

[0044] The device base 101 and the wire plate 102 are installed in an integrated manner. The connection method between the device base 101 and the wire threading plate 103 is a sliding connection. The wire threading plate 103 is composed of a threading plate and a base. The device base 101 cooperates with the wire threading plate 103 to thread the chemical fiber yarn to ensure smooth subsequent processing.

[0045] The first threaded block 201 is connected to the driving screw rod 202 by threaded connection. The first threaded block 201 and the connecting block 203 move in an integrated manner. The first threaded block 201 and the device base 101 are connected by rotational connection. The first threaded block 201 cooperates with the driving screw rod 202 to drive the first threaded block 201 to move, thereby driving the upper connecting block 203 to move, so that the threading plate 103 moves.

[0046] Elastic brushes 205 are evenly and equidistantly distributed on both sides of the connection block 203. The elastic brushes 205 are integrated with the fixing block 204. The fixing block 204 is connected to the device base 101 by hot-melt connection. The slots on both sides of the connection block 203 are sealed by the elastic brushes 205 to prevent the chemical fiber from falling into the inside of the connection slot during use, causing accidents.

[0047] The specific working principle is: first, during use, the chemical fiber yarn is threaded through the threading plate 103 and the steel wire plate 102. At this time, the connecting grooves on both sides of the connecting block 203 are mutually abutted by the elastic brushes 205 to complete the sealing work. The chemical fiber yarn falling on the top of the device base 101 will be blocked. Then, during use, if it is necessary to move the position of the threading plate 103, turn on the switch of the driving motor 206 to rotate the driving screw 202, thereby generating a threaded motion with the first threaded block 201. Then the first threaded block 201 drives the connecting block 203 to move, so that the threading plate 103 moves. During the movement, the connecting block 203 pushes the elastic brush 205 to move. After the movement process, the elastic brush 205 is reset, so that the connecting groove is always in a sealed state to prevent the chemical fiber yarn from falling inside.

[0048] Example 2, refer to Figure 1-2 In this embodiment, in order to solve the problem that the existing chemical fiber yarn is easily affected by the inconsistency of tightness, the threading work is easily affected, based on the same concept as the above-mentioned embodiment 1, the threading device for chemical fiber production also includes:

[0049] The anti-loosening assembly 300 also includes an auxiliary block 301, which is located above the device base 101. A reset spring 303 is connected to the lower center of the auxiliary block 301. The reset spring 303 drives the anti-loosening block 304 to move, so that the anti-loosening block 304 can be lifted up and down, thereby pushing the chemical fiber yarn to make it appropriately tight. The anti-loosening block 304 is connected below the reset spring 303, and a limiting rod 302 is connected above the anti-loosening block 304. The limiting rod 302 is used to limit the anti-loosening block 304 to prevent the anti-loosening block 304 from being unstable and affecting the stability of the chemical fiber yarn. A rubber block 305 is connected below the anti-loosening block 304.

[0050] The auxiliary block 301 is installed in an integrated manner with the device base 101. The auxiliary block 301 forms a spring reset structure with the anti-loosening block 304 through the reset spring 303. The interior of the reset spring 303 is connected in parallel with a shock absorber. The auxiliary block 301 cooperates with the reset spring 303, so that the anti-loosening block 304 automatically rises and falls, pushing the chemical fiber yarn to rise and fall, so that the chemical fiber yarn is appropriately tensioned.

[0051] The anti-loosening block 304 and the rubber block 305 are installed in an integrated manner. The limit rods 302 are symmetrically distributed above the anti-loosening block 304. The limit rods 302 are composed of two slidably connected straight rods. The two sides of the rubber block 305 are arc-shaped corner structures. The anti-loosening block 304 cooperates with the limit rods 302 to ensure that the anti-loosening block 304 can be stably raised and lowered. At the same time, the rubber block 305 is used to protect the chemical fiber yarn to prevent it from damaging the chemical fiber yarn during use.

[0052] The specific working principle is: as mentioned above, during use, the chemical fiber thread passes through the bottom of the anti-loosening block 304, and then the threading work is carried out. At this time, if the chemical fiber thread is too loose, the return spring 303 drives the anti-loosening block 304 to descend, so that the chemical fiber thread is in a tensioned state, and when the chemical fiber thread is too tight, it will squeeze the anti-loosening block 304. The rear return spring 303 gives the anti-loosening block 304 a thrust to prevent it from being too tight, and when the anti-loosening block 304 is raised or lowered, the limit rod 302 slides to limit the anti-loosening block 304 to prevent it from shaking when it is raised or lowered.

[0053] Example 3, refer to Figure 4-5 In this embodiment, in order to solve the problem that the existing threading plate 103 is too far away from the auxiliary block 301 when it moves to both sides, which may affect the tightness of the chemical fiber, based on the same concept as the above-mentioned embodiment 1, the threading device for chemical fiber production also includes:

[0054] The linkage assembly 400 also includes a second threaded block 401, which is located on the outside of the driving screw 202. The front side of the second threaded block 401 is connected to the linkage block 402, and the bottom plate 403 is driven to move by the linkage block 402, thereby driving the auxiliary block 301 to move. The left side of the linkage block 402 is connected to the bottom plate 403, and the left side of the bottom plate 403 is connected to the first slider 404. The first slider 404 is used to ensure that the bottom plate 403 moves stably without shaking or other problems.

[0055] The second threaded block 401 drives the screw rod 202 by threaded connection. The driving screw rod 202 and the linkage block 402 are installed in an integrated manner. The linkage block 402 and the base plate 403 are connected by hot melt connection. The second threaded block 401 cooperates with the linkage block 402 to drive the base plate 403 to move, so that the auxiliary block 301 and the threading plate 103 move in an integrated manner.

[0056] The bottom plate 403 forms a sliding structure with the device base 101 through the first slider 404. The bottom plate 403 and the auxiliary block 301 are installed in an integrated manner. The second sliders 405 are symmetrically distributed on both sides below the auxiliary block 301. The auxiliary block 301 is assisted in sliding by the first slider 404 and the second slider 405 to ensure that it is stable during the sliding process without shaking.

[0057] The specific working principle is: as mentioned above, during use, when the threading plate 103 is in use, the driving screw 202 and the second threaded block 401 undergo threaded motion, thereby moving the second threaded block 401, and then the second threaded block 401 drives the bottom plate 403 to move through the linkage block 402, so that the auxiliary block 301 above the bottom plate 403 moves, and at the same time, when the bottom plate 403 moves, it slides with the device base 101 through the first slider 404, and the auxiliary block 301 slides with the device base 101 through the second slider 405, to ensure stable sliding.

[0058] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
