Description

Technical Field

[0001] This utility model relates to the technical field of rewinding devices, specifically to a rewinding device for textiles. Background Technology

[0002] The winding device is generally used in textile processes and is a necessary step before weaving fabric. It has played a very important role in the history of textile technology development. Its main function is to wind the textile thread wound on the pay-off spool onto the take-up spool.

[0003] In existing technologies, rewinding devices typically use a winding motor to drive the winding drum directly. During winding, the traditional guide rollers are fixed in position, leading to unstable initial tension and a tendency for unwinding, thus affecting the quality of the rewinding. Furthermore, after the textile yarn guided by the guide rollers has been wound, it is inconvenient to replace the winding drum, wasting considerable time and reducing rewinding efficiency. Therefore, a textile rewinding device is needed to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rewinding device for textiles to solve the problems mentioned in the background art. This utility model has a reasonable structure, is easy to replace, has high rewinding efficiency, and high rewinding quality.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a textile rewinding device, comprising:

[0006] The base has an organic body on top and a yarn feeding drum placed on top. The side wall of the machine body is provided with guide wheels for guiding the textile yarn. The top of the machine body is provided with a pair of upright plates, one of which has a winding motor on its side wall, and a winding drum is provided on the output shaft of the winding motor.

[0007] An L-shaped groove is provided on the side of the machine body near the wire feeding drum. An electric cylinder is installed on the inner wall of the L-shaped groove. Multiple guide wheels are provided. The uppermost guide wheel is located on the sliding block of the electric cylinder. The distance from the axis of the other guide wheels to the vertical plane of the L-shaped groove is greater than the distance from the axis of the middle guide wheel to the vertical plane of the L-shaped groove.

[0008] Furthermore, both ends of the take-up drum are connected to clamps, one of which is connected to the output shaft of the take-up motor, and the other clamp has a connecting post at its end. The connecting post is rotatably connected to another vertical plate. The machine body is provided with a drive assembly for driving a pair of vertical plates to move toward each other or away from each other to clamp or release the take-up drum.

[0009] Furthermore, the chuck includes a clamping post disposed at the end of the connecting post or the end of the output shaft of the take-up motor, and a square locking block is provided at one end of the clamping post near the take-up drum;

[0010] The winding drum has a square slot at one end near the clamping post that matches the square locking block.

[0011] Furthermore, a guide groove is provided on the top of the body;

[0012] The upright plate includes a guide block disposed inside the guide groove, and a connecting plate is disposed on the top of the guide block;

[0013] The winding motor, the connecting column, and the connecting plate are connected.

[0014] Furthermore, a connecting bearing is provided at the connection between the connecting column and the connecting plate.

[0015] Furthermore, the drive assembly includes a drive motor disposed on the side wall of the machine body, and a bidirectional lead screw is provided on the output shaft of the drive motor, which penetrates through a pair of upright plates and is located inside the guide groove. The guide groove is symmetrically provided with limiting posts that penetrate through a pair of upright plates.

[0016] The bidirectional lead screw and the limiting post respectively pass through the guide block in the vertical plate.

[0017] Furthermore, three guide wheels are provided, and the distance from the axis of the other two guide wheels to the vertical plane of the L-shaped groove is greater than the distance from the axis of the middle guide wheel to the vertical plane of the L-shaped groove.

[0018] Furthermore, a fixing post is provided on the top of the base, the wire feeding drum is sleeved on the side wall of the fixing post, and a threaded pressure rod for pressing the top of the wire feeding drum is provided on the top of the fixing post.

[0019] Furthermore, the side wall of the machine body is provided with a placement groove for placing the wire feeding spool.

[0020] The beneficial effects achieved by the present invention using the above structure are as follows:

[0021] This invention uses a drive assembly to move a pair of upright plates toward one side closer to or further away from each other, thereby moving a pair of clamps toward one side closer to or further away from each other, to clamp or release the winding drum. This facilitates the replacement of the winding drum, saves time, and improves the efficiency of drum rewinding.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] like Figure 1 As shown, this utility model provides a technical solution: a textile rewinding device, comprising:

[0032] A base 1, a body 2 is set on the top of the base 1, a wire feeding drum 11 is placed on the top of the base 1, a guide wheel 10 for guiding the textile thread is set on the side wall of the body 2, a pair of upright plates 4 are set on the top of the body 2, a winding motor 5 is set on the side wall of one of the upright plates 4, and a winding drum 6 is set on the output shaft of the winding motor 5.

[0033] An L-shaped groove 102 is provided on the side of the machine body 2 near the pay-off drum 11. An electric cylinder 9 is installed on the inner wall of the L-shaped groove 102. Multiple guide wheels 10 are provided, with the uppermost guide wheel 10 located on the sliding block of the electric cylinder 9. The distance from the axis of the other guide wheels 10 to the vertical plane of the L-shaped groove 102 is greater than the distance from the axis of the middle guide wheel 10 to the vertical plane of the L-shaped groove 102. This design achieves dynamic tension adjustment by winding the textile yarn sequentially from bottom to top around the side walls of multiple guide wheels 10 and then connecting it to the take-up drum 6. The uppermost guide wheel 10 is driven by the electric cylinder 9 to move within the L-shaped groove 102. Combined with the asymmetrical layout of the multiple guide wheels 10, this design prevents yarn slack and improves the quality of the winding.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The take-up drum 6 has chucks 7 inserted at both ends. One chuck 7 is connected to the output shaft of the take-up motor 5, and the other chuck 7 has a connecting post 8 at its end. The connecting post 8 is rotatably connected to another vertical plate 4. The machine body 2 is equipped with a drive assembly 3 for driving the pair of vertical plates 4 to move closer to or further away from each other to clamp or release the take-up drum 6. This design uses the drive assembly 3 to move the pair of vertical plates 4 closer to or further away from each other, thereby moving the pair of chucks 7 closer to or further away from each other, completing the clamping or releasing of the take-up drum 6. This facilitates the replacement of the take-up drum 6, saves time, and improves the efficiency of drum rewinding.

[0035] Reference Figure 4 The chuck 7 includes a chuck 71 disposed at the end of the connecting post 8 or the end of the output shaft of the take-up motor 5, and a square locking block 72 is disposed at one end of the chuck 71 near the take-up drum 6.

[0036] The take-up drum 6 has a square slot 61 at one end near the clamping post 71 that matches the square clamping block 72. This design connects the square clamping block 72 on the chuck 7 with the square slot 61 at the end of the take-up drum 6, preventing the take-up drum 6 from slipping when the take-up motor 5 drives the take-up drum 6 to rotate, thus improving the stability of the take-up. The clamping post 71 fits against the end of the take-up drum 6, improving the stability of clamping the take-up drum 6.

[0037] Reference Figure 1 and Figure 2 The top of the body 2 is provided with a guide groove 103;

[0038] The upright plate 4 includes a guide block 42 disposed inside the guide groove 103, and a connecting plate 41 is disposed on the top of the guide block 42;

[0039] The winding motor 5, connecting column 8, and connecting plate 41 are connected. This design improves the stability of the drive assembly 3 driving the vertical plate 4 to move along the guide groove 103 via the guide block 42 on the vertical plate 4.

[0040] Reference Figure 1 and Figure 4 A connecting bearing 81 is provided at the connection between the connecting column 8 and the connecting plate 41. This improves the rationality of the design.

[0041] Reference Figure 1 and Figure 3 The drive assembly 3 includes a drive motor 31 disposed on the side wall of the body 2. The output shaft of the drive motor 31 is provided with a bidirectional lead screw 32 that penetrates a pair of upright plates 4 and is located inside the guide groove 103. The guide groove 103 is symmetrically provided with limiting posts 33 that penetrate a pair of upright plates 4.

[0042] The bidirectional lead screw 32 and the limiting post 33 respectively pass through the guide block 42 in the vertical plate 4. This design uses the drive motor 31 in the drive assembly 3 to drive the bidirectional lead screw 32 to rotate. The rotation of the bidirectional lead screw 32 causes the guide block 42 in the vertical plate 4 to move along the guide groove 103 to one side closer to or further away from each other. The movement of the guide block 42 causes the chuck 7 on the connecting plate 41 to move to one side closer to or further away from each other, thus completing the clamping or loosening of the winding drum 6. This facilitates the replacement operation of the winding drum 6, saves time, and improves the efficiency of drum rewinding.

[0043] Reference Figure 1 and Figure 2 There are three guide wheels 10. The uppermost guide wheel 10 is located on the sliding block of the electric cylinder 9. The distance from the axis of the other two guide wheels 10 to the vertical surface of the L-shaped groove 102 is greater than the distance from the axis of the middle guide wheel 10 to the vertical surface of the L-shaped groove 102. This design facilitates the S-shaped winding of the textile thread and effectively prevents the textile thread from becoming loose.

[0044] Reference Figure 2 and Figure 5 The base 1 has a fixed post 13 on its top, and the pay-off drum 11 is fitted onto the side wall of the fixed post 13. The fixed post 13 has a threaded pressure rod 12 on its top for pressing the top of the pay-off drum 11. This design uses the threaded pressure rod 12 to be threadedly connected to the fixed post 13 to press the top of the pay-off drum 11, improving the stability of the pay-off drum 11. The threaded connection also facilitates the replacement of the pay-off drum 11. The threaded rod includes a threaded post and a pressure plate. The pressure plate is located on the top of the threaded post and is used to press the pay-off drum 11. At the same time, a force groove is opened on the side wall of the pressure plate to facilitate the application of force to the threaded rod.

[0045] Reference Figure 1 The machine body 2 has a placement slot 101 on its side wall for placing the wire feeding spool 11. This design facilitates the placement of the wire feeding spool 11.

[0046] Reference Figures 1-5As an embodiment of this utility model: when it is necessary to wind up the textile thread, the worker places the unwinding drum 11 on the fixed column 13 and presses the drum body of the unwinding drum with the threaded pressure rod 12, so that the textile thread passes through multiple guide rollers 10 and connects to the winding drum 6. Then, the winding motor 5 drives the winding roller to rotate and wind up the textile thread. During the winding process, the electric cylinder 9 drives the guide rollers 10 on it to move, so that the textile thread is evenly guided to the side wall of the winding drum 6. The uppermost guide roller 10 is driven by the electric cylinder 9 to move in the L-shaped groove 102. Combined with the asymmetrical layout of multiple guide rollers 10, dynamic tension adjustment is achieved, the yarn is prevented from loosening, and the winding quality is improved.

[0047] After winding is complete, the drive motor 31 in the drive assembly 3 drives the bidirectional lead screw 32 to rotate. The rotation of the bidirectional lead screw 32 causes the guide blocks 42 on the pair of upright plates 4 to move to the side away from each other. The movement of the guide blocks 42 causes the connecting plate 41 to move to the side away from each other. By gripping the take-up drum 6, the connecting plate 41 moves and causes the chuck 7 to disengage from the inside of the take-up drum 6, making it easy to remove the take-up drum 6. Next, the square slot 61 at the end of the new take-up drum 6 is connected to the square block 72 in the chuck connected to the take-up motor 5. The clamping post 71 on the chuck is in contact with the end of the take-up drum 6. Finally, the drive motor 31 drives the bidirectional lead screw 32 to rotate, causing the upright plates 4 to move to the side closer to each other. This causes the directional block in the chuck 7 connected to the connecting post 8 to insert into the square slot 61 at the end of the take-up drum 6, making it easy to clamp the take-up drum 6 and complete the take-up drum 6 replacement operation.

[0048] The drive assembly 3 drives the chuck 7 to move towards or away from each other, thereby clamping or releasing the take-up drum 6. This facilitates the replacement of the take-up drum 6, saves time, improves the efficiency of drum rewinding, and enhances the practicality of this invention.
