Abstract
Description
Technical Field
[0001] This utility model relates to the field of untwisted elastic yarn machine technology, and in particular to a tension adjustment device for untwisted elastic yarn machine. Background Technology
[0002] Untwisted elastic yarn utilizes the thermoplastic properties of synthetic fibers such as polyester and nylon. The fibers are heated and shaped during twisting and curling to fix their twisted and curled state, resulting in a fluffy, elastic, and untwisted elastic yarn. Because the yarn has a slight torque but no twist, it has good elasticity, hence the name untwisted elastic yarn. Due to its good elasticity, a tension adjustment device is needed to adjust the tension during transmission.
[0003] Traditional tension adjustment devices are very complicated to adjust, which not only consumes a lot of time, but also has poor adjustment accuracy, thus greatly reducing their effectiveness.
[0004] Therefore, those skilled in the art have provided a tension adjustment device for untwisted elastic yarn machines to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tension adjustment device for untwisted elastic yarn machines. Firstly, a drive motor located at the top of a pad drives a driving bevel gear at its output end to rotate. Since the driving bevel gear meshes with the driven bevel gear, a sliding block threaded in the middle of the lead screw moves up and down. This ultimately adjusts the pressure roller rotating on one side of the sliding block. The up-and-down movement of the pressure roller allows for flexible adjustment of the elastic yarn tension, significantly improving the device's effectiveness.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A tension adjusting device for an untwisted elastic yarn machine includes a frame plate. A fixing groove is provided on one side of the frame plate. A lead screw is rotatably mounted at the bottom of the fixing groove. A driven bevel gear is provided at the top of the lead screw. A support plate is fixedly mounted at one end of the top center of the frame plate. A pad is provided at the top of the support plate. A drive motor is provided at the top of the pad. A driving bevel gear is provided at the output end of the drive motor. The driving bevel gear and the driven bevel gear are meshed together. A sliding block is threadedly fitted in the middle of the lead screw. A pressure roller is rotatably mounted on one side of the sliding block.
[0008] Through the above technical solution, the drive motor set at the top of the pad drives the active bevel gear set at the output end of the drive motor to rotate. Since the active bevel gear and the driven bevel gear are meshed, the sliding block threaded in the middle of the screw can move up and down. Finally, the pressure roller set on one side of the sliding block can be adjusted up and down. The tension of the elastic wire can be flexibly adjusted by the up and down movement of the pressure roller, which greatly improves the use effect of the device.
[0009] Furthermore, extension plates are fixedly installed at the bottom ends of both sides of the frame plate, and a pair of fixing bolts are fixedly installed at the top ends of the two pairs of extension plates.
[0010] The above technical solution facilitates the installation and fixation of the frame by fixing extension plates at the bottom of both sides of the frame and a pair of fixing bolts at the top of each pair of extension plates.
[0011] Furthermore, a pair of first limiting rollers are rotatably provided on one side of the front end face of the frame plate;
[0012] The above technical solution allows for the convenient limitation of the position of the elastic wire by rotating a pair of first limiting rollers on one side of the front end face of the frame.
[0013] Furthermore, a second limiting roller is rotatably provided at the end of the front end face of the frame plate away from the pair of first limiting rollers;
[0014] The above technical solution involves rotatably setting a second limiting roller at the end of the front face of the frame away from a pair of first limiting rollers, thereby facilitating the generation of tension in the elastic wire through the cooperation between the second limiting roller and the pair of first limiting rollers.
[0015] Furthermore, a tension sensor is provided at the outer end of the pressure roller;
[0016] The above technical solution allows for easy detection of the tension of the elastic wire as it passes through the pressure roller by installing a tension sensor at the outer end of the pressure roller.
[0017] Furthermore, the bottom end of the support plate is provided with inclined reinforcing ribs connecting to the rear end face of the frame plate;
[0018] The above technical solution, by setting inclined reinforcing ribs at the bottom end of the support plate and the rear end face of the frame plate, can greatly improve the strength of the support plate.
[0019] This utility model has the following beneficial effects:
[0020] 1. The tension adjustment device for an untwisted elastic yarn machine proposed in this utility model firstly drives the active bevel gear at the output end of the drive motor to rotate through the drive motor set at the top of the pad. Since the active bevel gear and the driven bevel gear are meshed, the sliding block threaded in the middle of the screw can move up and down, and finally realize the process of adjusting the pressure roller rotated on one side of the sliding block. The tension of the elastic yarn can be flexibly adjusted by the up and down movement of the pressure roller, which greatly improves the use effect of the device.
[0021] 2. The tension adjustment device for an untwisted elastic yarn machine proposed in this utility model facilitates the installation and fixation of the frame plate by fixing extension plates at the bottom of both sides of the frame plate and fixing bolts at the top of the two pairs of extension plates. The strength of the support plate can be greatly improved by setting inclined reinforcing ribs at the bottom end of the support plate and the rear end face of the frame plate. The tension sensor at the outer end of the pressure roller facilitates the detection of the tension of the elastic yarn when it passes through the pressure roller. Attached Figure Description

The drive motor 13 mounted on the top of the pad 12 drives the drive bevel gear 14 mounted on the output end of the drive motor 13 to rotate. Since the drive bevel gear 14 meshes with the driven bevel gear 9, the sliding block 6 threaded in the middle of the lead screw 5 can move up and down, and finally realize the process of adjusting the pressure roller 7 rotatably mounted on one side of the sliding block 6. The tension of the elastic wire can be flexibly adjusted by the up and down movement of the pressure roller 7, which greatly improves the use effect of the device.
[0031] Extension plates 2 are fixedly installed on both bottom ends of the frame plate 1, and a pair of fixing bolts 3 are fixedly installed on the top of each pair of extension plates 2.
