Description

Technical Field

[0001] The utility model relates to the technical field of warp knitting machines, and specifically relates to a guiding device based on a guiding roller of a warp knitting machine. Background Technique

[0002] A warp knitting machine mainly consists of a knitting mechanism, a lateral movement mechanism, a warp feeding mechanism, a pulling and winding mechanism, and a transmission mechanism. Among them, the function of the warp feeding mechanism is to unwind the warp yarns on the warp beam and feed them into the knitting area. In order to better convey the yarns, guiding rollers are usually arranged at the warp feeding mechanism to guide the yarns.

[0003] For a currently used guiding device based on a guiding roller of a warp knitting machine, through retrieval, it is found that the utility model with the patent publication number CN220907817U discloses a guiding device based on a guiding roller of a warp knitting machine, which includes a plurality of wire guiding structures. The plurality of wire guiding structures are linearly arranged along the axial direction of the guiding roller on the guiding roller. In one guiding structure, two semi-circular bodies can be connected through the semi-circular blocks at their two ends to form a circular body, and a group of yarns are guided through this cylinder. The semi-circular blocks can limit the yarns; the semi-circular bodies are in contact with the guiding roller through the rubber layer, which can effectively prevent excessive relative sliding between the semi-circular bodies and the guiding roller.

[0004] Although the above patent solves the problems in the above background technique, there are still the following deficiencies: In the device, the semi-circular blocks are connected by screws. This connection method is cumbersome to operate and requires a lot of time, thus affecting the installation efficiency between the upper guiding ring block and the lower guiding ring block, and is not conducive to subsequent adjustment of the guiding position of the yarns.

[0005] In summary, the utility model designs a guiding device based on a guiding roller of a warp knitting machine to solve the problems in the above background technique. Content of the Utility Model

[0006] The purpose of the utility model is to provide a guiding device based on a guiding roller of a warp knitting machine to solve the problems put forward in the above background technique.

[0026] For the embodiments, please refer to Figures 1-3 , this utility model provides a technical solution:

[0027] A guiding device based on a guide roller of a warp knitting machine, including a warp knitting machine body 1. Mounting frames 2 are fixedly installed on the rear side of the warp knitting machine body 1 respectively. A locking bolt 201 is arranged on the top of the mounting frame 2. Support columns 202 are arranged on the front side of the mounting frame 2. Threaded holes 203 are formed on the outer surface of the support column 202. Mounting blocks 204 are fixedly installed at the front ends of the support columns 202. A guide roller 3 is arranged between the mounting blocks 204. An upper guide ring block 301 and a lower guide ring block 302 are respectively sleeved on the outer side of the guide roller 3. An installation mechanism 4 is arranged between the upper guide ring block 301 and the lower guide ring block 302;

[0028] Specifically, the rear end of the support column 202 fits through the front side surface of the mounting frame 2 and extends backward. The bottom end of the locking bolt 201 movably passes through the top surface of the mounting frame 2 and is threadedly connected to the threaded hole 203;

[0029] In this implementation scheme, through the fitting and sliding of the support column 202 and the mounting frame 2, the position movement of the guide roller 3 is realized, which is convenient for subsequent adjustment operations.

[0030] Specifically, one end of the upper guide ring block 301 and the lower guide ring block 302 is rotatably connected by a shaft body, and rubber friction pads are arranged on their inner sides;

[0031] In this implementation scheme, through the setting of the rubber friction pads, the friction between the upper guide ring block 301, the lower guide ring block 302 and the guide roller 3 is increased, which is beneficial for subsequent use.

[0032] In this embodiment, please refer to Figure 2 and Figure 3, the installation mechanism 4 includes an upper fastening block 401, a lower fastening block 402 and an installation groove 403. The upper fastening block 401 is fixedly installed at the rear side of the upper guide ring block 301, and a limit post 404 is provided at the bottom thereof. An eccentric block 405 is provided at the bottom of the limit post 404. The lower fastening block 402 is fixedly installed at the rear side of the lower guide ring block 302, and a limit groove 406 is provided at the outer rear end thereof. The installation grooves 403 are respectively provided on the left and right end surfaces of the upper guide ring block 301, and a support compression spring 407 is installed inside thereof;

[0033] Specifically, the outer surface of the limit post 404 is in close contact with the limit groove 406, and its cross-sectional shape is the same as that of the eccentric block 405. The eccentric block 405 eccentrically rotates with respect to the bottom surface of the limit post 404 through a pin shaft, and its top surface is in contact with the bottom surface of the lower fastening block 402. The inner wall of the bottom end of the installation groove 403 extends to the bottom of the upper guide ring block 301. The top end of the support compression spring 407 is fixed to the inner wall of the top end of the installation groove 403, and its bottom end is in contact with the top of the lower guide ring block 302;

[0034] In this embodiment, through the elastic extension of the support compression spring 407, the upper guide ring block 301 and the lower guide ring block 302 are separated. Under the close contact between the limit post 404 and the limit groove 406, the upper guide ring block 301 and the lower guide ring block 302 are brought closer. And due to the eccentric setting of the eccentric block 405, the eccentric block 405 is closely attached to the bottom surface of the lower guide ring block 302, thus achieving the function of conveniently installing the upper guide ring block 301 and the lower guide ring block 302 and meeting the needs of the user.

[0035] The working process of the present utility model: When using a guiding device based on a guide roller of a warp knitting machine, first adjust the position of the guide roller 3 as required, move the support column 202 along the inner wall of the mounting frame 2. At this time, the guide roller 3 moves along with the movement of the support column 202. Through the threaded cooperation between the locking bolt 201 and the threaded hole 203, the fixing of the support column 202 is realized, thereby realizing the position adjustment of the guide roller 3. Finally, the position of the yarn can be guided through the upper guide ring block 301. When it is necessary to adjust the position of the upper guide ring block 301, rotate the eccentric block 405 to make the eccentric block 405 coincide with the limit post 404. At this time, under the action of the support compression spring 407, the limit post 404 and the limit groove 406 are gradually separated, so that the upper guide ring block 301 and the lower guide ring block 302 are separated. Thus, the upper guide ring block 301 and the lower guide ring block 302 can be moved, thereby realizing the function of quickly adjusting the position of the guide ring block and meeting the guiding requirements of the yarn.

[0036] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
