Description

Technical Field

[0001] The utility model relates to the technical field of polyester filament production, in particular to a tangent mechanism for polyester filament. Background Art

[0002] When processing polyester filaments, in order to facilitate the storage and subsequent use of polyester filaments, they need to be wound to form polyester filament cake plates, which are convenient for the removal, application and transportation of polyester filaments. After the winding is completed, the filaments need to be cut to improve the stable and orderly efficiency of continuous winding and winding. In order to improve the efficiency and stability of cutting, it is necessary to use cutting equipment instead of manual assisted cutting.

[0003] For example, the Chinese patent number CN219525870U is a polyester filament cutting device. In this utility model, the cut polyester filaments are wound up by directly connecting the drive motor to the winding roller. However, due to the connection between the winding roller and the drive motor in this utility model, the difficulty of disassembling and assembling the winding roller is increased, which is not conducive to the user to collect the cut polyester filaments for subsequent processing and production use, resulting in reduced processing efficiency of the polyester filaments, which is not conducive to user use. Therefore, a polyester filament tangent mechanism is proposed to solve the above problem. Utility Model Content

The U-shaped structure is utilized to allow the connecting column 408 to rotate inside the U-shaped hole 402, thereby facilitating the wire-receiving operation. Two support rods 403 are installed on the front side of the front bracket plate 401, and the support positioning block 405 is used to set up a servo motor 406 for driving. A positioning pin 404 is installed on the top of the support rod 403 for cooperating with the positioning block 405 to engage the position of the limit servo motor 406.

[0027] It should be noted that this section is intended to provide a background or context for the implementation methods stated in the claims, and detailed descriptions of known functions and known components are omitted. At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.

[0028] When implementing, follow these steps:

[0029] 1) First, rotate the winding roller 407 so that the direction of the dovetail hole is consistent with the direction of the top through hole of the U-shaped hole 402;

[0030] 2) Then, pull the winding roller 407 upward to drive the front and rear connecting columns 408 to move synchronously, so that the dovetail hole and the dovetail block 409 are gradually separated;

[0031] 3) Finally, the winding roller 407 continues to move until the connecting column 408 leaves the U-shaped hole 402, so that the winding roller 407 drives the polyester filament wound thereon to leave the tangent mechanism.

[0032] To sum up, the tangent mechanism of the polyester filament is provided with a U-shaped hole 402, so that the connecting column 408 is easy to be placed on the bracket plate 401, thereby reducing the difficulty of installing the winding roller 407. At the same time, the inner bottom wall of the U-shaped hole 402 is a smooth arc, so that the connecting column 408 is driven by the dovetail block 409 to rotate inside the U-shaped hole 402, thereby ensuring that the winding roller 407 can normally reel in the cut polyester filament, ensuring the normal progress of the processing process, and reducing the difficulty of installing the winding roller 407, making it convenient for the user to replace the winding roller 407 for collection operations, thereby improving the efficiency of polyester filament processing, and thus facilitating the use of the user.

[0033] Moreover, by utilizing the engagement of the dovetail block 409 with the dovetail hole, the output shaft of the servo motor 406 is connected to the connecting column 408 on the front side of the winding roller 407 through the dovetail block 409, so that the rotation of the output shaft of the servo motor 406 can drive the winding roller 407 to rotate. At the same time, the engagement of the dovetail block 409 with the dovetail hole reduces the difficulty of disassembling the connecting column 408 and the output shaft of the servo motor 406, which is convenient for the user to carry out the disassembly and replacement operation. The servo motor 406 is installed by engaging the pin hole on the positioning block 405 with the positioning pin 404 on the support rod 403, which is convenient for the user to disassemble and maintain the servo motor 406, reduces the user's maintenance cost, and solves the problem of high difficulty in disassembling and assembling the winding roller in the comparative document, which reduces the user's collection efficiency and affects the processing efficiency of polyester filament.
