Description

Technical Field

[0001] This utility model relates to the field of rewinding machine technology, and more specifically to a rewinding machine for winding lace webbing. Background Technology

[0002] As textile fabrics are used in more and more fields, the requirements for the finished fabric surface effect of lace fabrics are also increasing. The quality of the yarn is closely related to the finished fabric surface effect of lace fabrics. Yarn is mostly stored on spools for processing into lace fabrics, and the winding machine is crucial in the yarn winding process.

[0003] Chinese Patent No. CN221565333U discloses an automatic winding drum machine, which includes two fixed plates positioned on a support plate, a threaded rod located between the two fixed plates and rotatably connected to the fixed plates, a brake motor for driving the threaded rod to rotate, two internal threaded blocks threaded to the threaded rod, a guide rod passing through the two internal threaded blocks and positioned at both ends on the fixed plates, two movable plates correspondingly connected to the two internal threaded blocks via connecting rods, and two locking blocks rotatably connected to the movable plates respectively. The brake motor drives the threaded rod to rotate, causing the two internal threaded blocks to move the corresponding movable plates and locking blocks in opposite directions, thus clamping the winding drum. The design has several flaws. During the loading and unloading of the spool, the operator needs to hold it up so that the two clamping blocks can grip it. This requires considerable effort from the operator, and the clamping blocks may not accurately engage with the spool's end face due to misalignment, leading to the spool easily falling off during rotation. During unloading, the operator must first hold the spool, then the two clamping blocks must move away to release the clamp. Because the wire wrapped around the spool increases its overall weight, if the operator applies insufficient lifting force, the spool is prone to falling, potentially injuring the operator's arm and posing a safety hazard. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rewinding machine that is convenient to install and safe to disassemble.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a winding machine for winding lace webbing thread, comprising a support plate, two fixed plates positioned behind the support plate, a threaded rod positioned between the two fixed plates, a guide rod positioned below the threaded rod, two internal threaded blocks threaded to the threaded rod and through which the guide rod passes, a brake motor for driving the threaded rod to rotate, two movable plates located in front of the support plate and connected to the internal threaded blocks, two locking blocks rotatably connected to the corresponding movable plates, and a winding drum clamped by the two locking blocks. Each of the two locking blocks has a T-shaped support block at one end facing each other. The winding drum has T-shaped stop grooves at the center of both ends for support by the support blocks. Two inlet grooves are provided on the peripheral wall, both extending along the diameter of the spool and communicating with two stop grooves respectively. The two inlet grooves are located on the same straight line and extend to the end face of the spool at one end along the length of the spool. The inner cavity of the two inlet grooves is T-shaped. The groove walls of the two inlet grooves facing each other are respectively connected to the groove walls of the corresponding stop grooves facing each other. The length of the two stop grooves along the length of the spool is greater than the length of the corresponding inlet grooves along the length of the spool. By moving the spool relative to the two support blocks from top to bottom, the two support blocks pass through the corresponding inlet grooves and touch the bottom of the stop grooves. By moving the two internal threaded blocks towards each other, the two support blocks move along the length of the spool, causing the support blocks to be misaligned with the corresponding inlet grooves.

[0006] As a further improvement of this utility model, the distance between the two opposing groove walls of the two feed grooves gradually increases in the direction from the center of the winding drum to the peripheral wall of the winding drum.

[0007] The beneficial effects of this utility model are as follows: By moving the spool relative to the two support blocks from top to bottom, the two support blocks pass through the corresponding infeed grooves and contact the bottom of the stop groove. By moving the two internal threaded blocks towards each other, the two support blocks move along the length of the spool and are misaligned with the corresponding infeed grooves. Compared with the prior art, this design can shorten the time for manually lifting the spool by supporting it with support blocks, making it easier for the operator to work continuously. In terms of clamping, the operation of first lifting the spool with support blocks and then clamping it can compensate for the defect that the snap-fit ​​block and the end face of the spool are eccentric and cannot be inserted, thus improving the clamping accuracy and efficiency. In terms of disassembly, using support blocks to lift the spool makes it easier for the operator to judge and adjust the force and handling method of lifting the spool, thus improving safety.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0020] Reference Figures 1 to 10 As shown, a winding machine for winding lace webbing thread according to this embodiment includes a support plate 1, two fixed plates 2 positioned behind the support plate 1, a threaded rod 3 positioned between the two fixed plates 2, a guide rod 4 positioned below the threaded rod 3, two internal threaded blocks 5 threaded to the threaded rod 3 and through which the guide rod 4 passes, a brake motor 6 for driving the threaded rod 3 to rotate, two movable plates 7 located in front of the support plate 1 and connected to the internal threaded blocks 5, two snap-fit ​​blocks 8 rotatably connected to the corresponding movable plates 7, and a winding drum 9 clamped by the two snap-fit ​​blocks 8. The winding drum 9 is a solid drum.

[0021] Based on the aforementioned prior art, each of the two snap-fit ​​blocks 8 has a T-shaped support block 10 integrally formed on one end facing each other. The winding drum 9 can be formed by two half-bodies bonded together facing each other. Two semi-central grooves, each located at the center of the half-bodies, are machined on the facing surfaces of the two half-bodies. One end of each of the two semi-central grooves extends to the two end faces of the half-bodies. Subsequently, two semi-grooves communicating with the two semi-central grooves are machined along the radial direction of the half-bodies. The ends of the two semi-grooves along the length direction of the half-bodies extend to the two end faces of the half-bodies, and the ends of the two semi-grooves along the diameter direction extend to the peripheral wall of the half-bodies. Then, on the two half-bodies... On the opposite ends of the grooves, an extension portion offset from the half groove is cut out. After the two half-cylinders are bonded together, the two half-grooves together form a stop groove 91 and a guide groove 92. The length of the stop groove 91 is greater than the length of the guide groove 92 due to the presence of the extension portion. The inner cavities of the stop groove 91 and the guide groove 92 are both T-shaped. The groove walls of the two guide grooves 92 facing each other are respectively connected to the groove walls of the corresponding stop grooves 91 facing each other. The width of the stop groove 91 matches the width of the support block 10. The wire is wound on the winding drum 9 to form a wire drum. The length of the wire drum is less than the distance between the two opposite ends of the guide grooves 92.

[0022] Initially, the cable drum 9 and the support block 10 are separated. During the clamping of the cable drum 9, the brake motor 6 drives the internal thread block 5, the movable plate 7, the locking block 8, and the support block 10 to move as a whole, adjusting the distance between the two support blocks 10 to be the same as the distance between the two infeed slots 92. The operation of the brake motor 6 is then stopped. The cable drum 9 is then moved above the plane where the support block 10 is located, with the two infeed slots 92 directly above the two support blocks 10. The cable drum 9 is then moved from top to bottom, and the two support blocks 10 enter the corresponding infeed slots 92 and move into the corresponding stop slots 91 until the support block 10 touches the bottom of the corresponding stop slot 91. The cable drum 9 is then released, and the cable drum 9 is lifted by the two support blocks 10. Then the brake motor 6 is started, and the two support blocks 10 move towards each other along the length of their respective stop slots 91, with some support blocks 10 partially entering the stop slot. The drum 9 is deep within the groove 91 and misaligned with the inlet groove 92. Finally, the brake motor 6 is stopped and the relevant winding operation is performed. The drum 9 and the support block 10 rotate relative to the movable plate 7. The drum 9 cannot detach from the support block 10 during the rotation. During the disassembly of the drum 9, the opening of the inlet groove 92 on the peripheral wall of the drum 9 is vertically downward. The rotation of the drum 9 is stopped. Then, the brake motor 6 drives the two support blocks 10 to move away from each other until the support block 10 touches the top of the groove wall of the stop groove 91. The support block 10 is directly opposite the inlet groove 92. The brake motor 6 stops operating. Then, the operator lifts the drum 9 with both hands and moves it upward. The support block 10 leaves the stop groove 91 and enters the inlet groove 92. The support block 10 moves along the inlet groove 92 and finally leaves the inlet groove 92. The drum 9 and the support block 10 are separated. Finally, the drum 9 is moved away and a new drum 9 is replaced for the next winding.

[0023] Compared to existing technologies, this design can shorten the time required to manually lift the drum 9 by supporting it with the support block 10, making it easier for operators to work continuously. In terms of clamping, the operation of first lifting the drum 9 with the support block 10 and then clamping it can compensate for the defect that the clamping block 8 and the end face of the drum 9 are misaligned and cannot be inserted, thus improving clamping accuracy and efficiency. In terms of disassembly, using the support block 10 to lift the drum 9 makes it easier for operators to judge and adjust the force and handling method of lifting the drum 9, thus improving safety.

[0024] As one specific implementation method of the improvement, refer to Figure 10 As shown, the distance between the two adjacent groove walls of the inlet groove 92 gradually increases from the center of the drum 9 towards the peripheral wall of the drum 9. The outline dimension of the inlet groove 92 on the peripheral wall of the drum 9 is larger than the outline dimension of the support block 10. During the movement of the drum 9 from top to bottom, the support block 10 enters the inlet groove 92 and slides relative to one of the groove walls of the inlet groove 92. The vertical plane where the center line of the drum 9 is located is close to the vertical plane where the support block 10 is located, until the center line of the drum 9 and the support block 10 are both on the same vertical plane. The support block 10 smoothly enters the stop groove 91. This design can reduce the difficulty of the support block 10 entering the inlet groove 92, improve the clamping efficiency, and at the same time, it can also adjust the drum 9 and the support block 10 to a coaxial position, so that the support block 10 can drive the drum 9 to rotate.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
