Description

Technical Field

[0001] This application relates to the field of yarn production and processing technology, and in particular to a yarn rewinding machine. Background Technology

[0002] A yarn rewinding machine is a mechanical device used in the textile process to remove small yarn curls and bobbin ends. Using a yarn rewinding machine can solve the problem of small yarn curls and bobbin ends in the production processes of chemical fiber, weaving, and hosiery companies.

[0003] In the production process of existing yarn rewinding machines, when there is not much yarn left on the rewinding drum and the equipment is running at high speed, the quality of the rewinding drum decreases due to the reduction of remaining yarn. This can easily cause the rewinding drum to jump repeatedly or even detach from the placement shaft, leading to problems such as yarn breakage and yarn entanglement. The equipment needs to be stopped for handling, which not only affects work efficiency but also poses safety hazards. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a yarn rewinding machine. The technical problem it solves is that under high-speed operation, the quality of the later-stage pay-off drum decreases due to reduced remaining yarn, leading to problems such as yarn breakage and tangling caused by repeated drum jumping. The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A yarn rewinding machine, comprising:

[0006] frame;

[0007] A crossbar is connected to the frame in a fixed structure, and a take-up drum holder is fitted on the crossbar.

[0008] The winding roller is connected to the frame via a rotating structure.

[0009] The wire guide is connected to the frame in a fixed manner;

[0010] The placement plate is connected to the lower end of the frame by a fixed structure.

[0011] A placement shaft is fixedly mounted on the upper surface of the placement plate, and springs A and B are fixedly mounted on the upper surface of the placement shaft.

[0012] The limiting block is connected to the spring A in a fixed structure, and a pressure block is fixedly provided on the upper end face of one side of the limiting block;

[0013] The vertical plate is fixedly mounted on the upper end face of the placement shaft.

[0014] The movable plate is connected to the vertical plate in a sliding structure along the vertical direction. A limit groove is opened at the lower end of the movable plate, and the movable plate is located above the spring B.

[0015] The card plate is fixedly mounted on the upper surface of the movable plate. The card plate is slidably connected to the pressure block, and the card plate has slots at both ends.

[0016] Furthermore, a connecting block A is fixedly installed on the upper end of spring A, and the connecting block A is in contact with the movable plate; a connecting block B is fixedly installed on the upper end face of spring B, and the connecting block B is fixedly connected to the limiting block.

[0017] Furthermore, a groove is provided on the end face of the vertical plate facing the movable plate, through which the movable plate is slidably connected to the vertical plate.

[0018] Furthermore, a stop block is fixedly installed at the upper end of the chute.

[0019] Furthermore, a column is fixedly installed on the upper end face of the pressure block, and the card plate is connected to the pressure block through the column in a sliding structure.

[0020] Furthermore, the lower end of the inner side of the card slot is made of hard rubber material.

[0021] Furthermore, the placement shaft is arranged in a frustum shape.

[0022] The beneficial effects of this utility model are: by setting a movable plate and a clamping plate, the clamping slots at both ends of the clamping plate can clamp the clamping plate to the upper edge of the pay-off drum, preventing the pay-off drum from repeatedly jumping or even detaching from the anti-thread shaft due to the reduction of yarn quality during high-speed operation, avoiding the problems of yarn entanglement and yarn breakage caused by this, ensuring the efficiency of the production line, and reducing potential safety risks.

[0023] By incorporating spring A, spring B, a limit block, and a pressure block, the operator can easily engage the clamping plate with the upper edge of the take-up drum through a simple pressing action. Pressing the upright allows the clamping plate to quickly detach from the pay-off drum. The structure is designed for convenient operation and enhances practicality. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0031] A yarn winding machine includes a frame 1. The frame 1 has a fixed structure with a crossbar 2, a yarn guide 5, and a placement plate 6. A take-up bobbin placement frame 3 is sleeved on the crossbar 2. The frame 1 also has a rotating winding roller 4. A placement shaft 7 is fixedly mounted on the upper surface of the placement plate 6. Springs A8 and B9 are fixedly mounted on the upper surface of the placement shaft 7. A limit block 10 is fixedly mounted on the upper part of spring A8. A pressure block 11 is fixedly mounted on one side of the upper surface of the limit block 10. A vertical plate 12 is fixedly mounted on the upper surface of the placement shaft 7. A movable plate 13 is slidably mounted on the vertical plate 12. A limiting groove 14 is provided at the lower end of the movable plate 13. The movable plate 13 is located above the spring B9. A clamping plate 15 is fixedly provided on the upper surface of the movable plate 13. The clamping plate 15 is slidably connected to the pressure block 11. The clamping plate 15 has a clamping groove 16 at both ends. By setting the movable plate 13 and the clamping plate 15, the clamping groove 16 at both ends of the clamping plate 15 can clamp the clamping plate 15 at the upper edge of the feed drum 22. This prevents the feed drum from repeatedly jumping or even detaching from the anti-thread shaft due to the reduction of yarn quality during high-speed operation. This avoids the problems of yarn entanglement and yarn breakage caused by this, ensuring the efficiency of the production line and reducing potential safety risks.

[0032] It should be noted that a connecting block A17 is fixedly installed on the upper end of spring A8. The connecting block A17 is abutted and connected to the movable plate 13. At this time, the clamping plate 15 is clamped at the edge of the wire feeding drum through the clamping groove 16. The limiting block 10 is partially located in the limiting groove 14. The movable plate 13 is connected to the connecting plate A. Spring A8 is in a compressed state. The connecting block A17 can provide a stable support point for the movable plate 13 and prevent the spring A8 from directly contacting the movable plate 13, reducing wear between components and extending service life. A connecting block B18 is fixedly installed on the upper end face of spring B9. The connecting block B18 is fixedly connected to the limiting block 10. The connecting block B18 provides a stable support point for the limiting block 10, preventing the limiting block 10 from shifting and ensuring that the head of the limiting block 10 is smoothly inserted into the limiting groove 14, thus fixing the movable plate 13.

[0033] It should be noted that a groove 19 is provided on the end face of the vertical plate 12 facing the movable plate 13. The movable plate 13 is slidably connected to the vertical plate 12 through the groove 19. This structure is mainly used for the up and down movement of the movable plate 13. A stop block 20 is fixedly provided at the upper end of the groove 19. The stop block 20 is designed to prevent the movable plate 13, along with the clamping plate 15, from detaching from the vertical plate 12 and leaving the placement shaft 7 under the elastic force of the spring A8.

[0034] It should be noted that a column 21 is fixedly provided on the upper end face of the pressure block 11, and the clamping plate 15 is connected to the pressure block 11 through the column 21 in a sliding structure. This structure facilitates the application of pressure to the pressure block 11, causing the limiting block 10 to disengage from the limiting groove 14, which facilitates the quick release of the clamping plate 15, improves operating efficiency, and provides a stable support for the clamping plate 15.

[0035] It should be noted that the lower end of the inner side of the slot 16 is made of hard rubber material; this structure is designed to ensure that the card plate 15 does not damage the wire feeding drum.

[0036] It should be noted that the placement shaft 7 is set in a frustum shape; this structure can ensure the stability of the pay-off drum during operation to a certain extent.

[0037] The working principle and process of this utility model are as follows:

[0038] Place the pay-off spool on the placement shaft 7, press down on the clamping plate 15, the clamping plate 15 moves down, and the movable plate 13 moves down with the clamping plate 15 until the movable plate 13 drives the limiting block 10 so that its head is locked into the limiting groove 14, and the groove 16 is just locked into the edge of the pay-off spool, giving the pay-off spool a downward pressure. At this time, the movable plate 13 presses on the connecting block A17, and the spring A8 is in a compressed state.

[0039] After all the yarn has been released from the pay-off spool, press down on the column 21. The column 21 applies downward pressure to the pressure block 11, which in turn applies pressure to the tail of the limit block 10. The head of the limit block 10 will then lift upward and leave the limit groove 14. At this point, the spring A8 will return to its initial state. The spring A8, through the connecting block A17, applies an upward elastic force to the movable plate 13. The movable plate 13 begins to move upward along the slide groove 19, and the locking plate 15 moves upward along with the movable plate 13. The locking groove 16 gradually disengages from the pay-off spool until it is completely disengaged from the edge of the pay-off spool. Then, remove the empty pay-off spool. When the limit block 10 leaves the locking groove 16 and the movable plate 13 moves upward to a point where its lower end face exceeds the highest point of the limit block 10, simultaneously release the column 21. The spring B9 will reset, and both the limit block 10 and the pressure block 11 will return to their initial states.

[0040] The card plate 15 and the movable plate 13 will eventually fall due to their own gravity, but their gravity is less than the pressure applied at the beginning. The lower end of the movable plate 13 will be blocked by the limiting block 10. Its own gravity will not cause the limiting block 10 to get stuck in the limiting groove 14 of the movable plate 13.
