[0002] Carding and spinning is a crucial process in the textile industry, transforming cotton or other fibers into yarn. Carding and spinning is a crucial step in producing high-quality yarn. As a key component of the carding and spinning machine, the drum must be frequently replaced during the carding and spinning process to ensure production continuity and yarn quality.
[0003] However, the traditional reel replacement method requires the operator to use tools, such as a wrench or screwdriver, to manually loosen the fixing bolts or clamps at both ends of the reel. Although this method can achieve reel replacement, the operation process is too cumbersome, time-consuming and labor-intensive, reducing work efficiency. Utility Model Content
[0004] In order to make up for the above shortcomings, the utility model provides a reel replacement structure for carding and spinning processing, which aims to improve the problem that the traditional reel replacement method in the prior art requires the operator to use tools such as a wrench or a screwdriver to manually loosen the fixing bolts or clamps at both ends of the reel.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A structure for replacing a reel for carding and spinning processing comprises a bracket, a mounting plate fixedly connected to the middle portion of the bracket, a fixing plate fixedly connected to the rear side of the upper portion of the mounting plate, a connecting plate fixedly connected to the upper portion of the fixing plate, a mounting block fixedly connected to the lower portion of the connecting plate, an auxiliary component provided inside the mounting block, the auxiliary component being used to assist in unwinding the reel, a first motor provided at the lower portion of the mounting plate, a rotating shaft fixedly connected to the output end of the first motor, a gear fixedly connected to the outside of the rotating shaft, a rack plate meshingly connected to the outside of the gear, a guide ring fixedly connected to the outside of the rack plate, a fixing rod fixedly connected to the upper portion of the rack plate, and a positioning plate fixedly connected to the top of the fixing rod.
[0007] Furthermore, the auxiliary component includes a double-headed motor, which is fixedly connected to the inside of the mounting block, and the output ends of the double-headed motor are fixedly connected to screw rods, and the exteriors of the two screw rods are threadedly connected to moving rings, and the lower parts of the two moving rings are rotatably connected to adjustment plates, and the other ends of the two adjustment plates are rotatably connected to cross plates, and the lower parts of the cross plates are rotatably connected to auxiliary rollers.
[0008] Furthermore, a second motor is provided outside the fixed plate, a turntable is fixedly connected to the output end of the second motor, a limiting rod is fixedly connected to the outside of the turntable, a reel body is sleeved on the outside of the turntable, and the other end of the turntable is plugged into the positioning plate.
[0009] Furthermore, a mounting bracket is fixedly connected to the lower portion of the mounting plate, and the first motor is fixedly connected to the inside of the mounting bracket.
[0010] Furthermore, a through hole is provided inside the mounting plate, and the fixing rod is slidably connected inside the through hole.

[0014] The utility model has the following beneficial effects:
[0015] 1. In the present invention, when the reel body needs to be replaced, the first motor is first started, driving the gear to rotate, thereby moving the meshing rack plate. The movement of the rack plate drives the fixed rod and the positioning plate to move, disengaging the positioning plate from the turntable. The reel body can now be removed. When installing a new reel, the above steps are repeated to engage the positioning plate with the turntable, making it easy to replace the reel. This solves the traditional reel replacement method that requires the operator to use tools such as a wrench or screwdriver to manually loosen the fixing bolts or clamps at both ends of the reel. This simple and convenient operation method improves work efficiency.
[0016] 2. In the present invention, when the reel is unwinding, the double-headed motor is activated, driving the two screws to rotate, pushing the two externally threaded movable rings to move relative to each other. The movable rings drive the relative movement of the adjustment plate, which in turn pushes the cross plate and auxiliary roller downward, bringing the auxiliary roller into contact with the exterior of the reel. This facilitates positioning of the yarn roll during unwinding, ensuring that the yarn roll remains stable during the unwinding process and prevents it from sliding or falling due to vibration or other reasons, thus avoiding damage to the yarn roll and improving production efficiency.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Reference Figure 1 、 Figure 3 and Figure 4, The utility model provides an embodiment: a reel replacement structure for carding and spinning, including a bracket 1, a mounting plate 2 is fixedly connected to the middle part of the bracket 1, a fixing plate 13 is fixedly connected to the upper rear side of the mounting plate 2, a connecting plate 16 is fixedly connected to the upper part of the fixing plate 13, a mounting block 17 is fixedly connected to the lower part of the connecting plate 16, an auxiliary component 18 is arranged inside the mounting block 17, and the auxiliary component 18 is used to assist the reel unwinding, a first motor 5 is arranged at the lower part of the mounting plate 2, a rotating shaft 6 is fixedly connected to the output end of the first motor 5, a gear 7 is fixedly connected to the outside of the rotating shaft 6, a rack plate 8 is meshed with the outside of the gear 7, a guide ring 9 is fixedly connected to the outside of the rack plate 8, a fixing rod 11 is fixedly connected to the upper part of the rack plate 8, and a positioning plate 12 is fixedly connected to the top of the fixing rod 11, A second motor 15 is provided on the outside of the fixed plate 13, and the output end of the second motor 15 is fixedly connected to a turntable 20, and a limit rod 21 is fixedly connected to the outside of the turntable 20. A drum body 19 is sleeved on the outside of the turntable 20, and the other end of the turntable 20 is plugged into the positioning plate 12. The lower part of the mounting plate 2 is fixedly connected to the mounting frame 4, the first motor 5 is fixedly connected to the inside of the mounting frame 4, a through hole 3 is opened inside the mounting plate 2, the fixed rod 11 is slidably connected to the inside of the through hole 3, the inside of the mounting plate 2 is fixedly connected to the guide rod 10, the guide ring 9 is slidably connected to the outside of the guide rod 10, an annular groove 22 is opened on the outside of the fixed plate 13, the limit rod 21 is slidably connected to the inside of the annular groove 22, the outside of the fixed plate 13 is fixedly connected to the U-shaped frame 14, and the second motor 15 is fixedly connected to the inside of the U-shaped frame 14.
[0026] To replace the reel 19, first start the first motor 5. This drives the gear 7 fixed to the output end. This rotation moves the rack plate 8 meshing with it. The movement of the rack plate 8 further moves the fixed rod 11 above it. This movement in turn moves the fixed positioning plate 12 above it, disengaging it from the turntable 20. At this point, the operator can easily remove the reel 19 from the outside of the turntable 20. To install a new reel, repeat the above steps. The new reel 19 is placed on the turntable 20, then the first motor 5 is started. The gear 7 again moves the rack plate 8, moving the fixed rod 11 and positioning plate 12 accordingly, engaging the positioning plate 12 with the turntable 20, completing the reel installation. This process not only facilitates reel replacement but also avoids the tedious manual loosening of the bolts or clamps at each end of the reel using tools such as a wrench or screwdriver, as is typical with traditional reel replacement methods.
[0027] Reference Figure 2 、 Figure 3 and Figure 5The auxiliary component 18 includes a double-headed motor 1801, which is fixedly connected to the inside of the mounting block 17. The output ends of the double-headed motor 1801 are fixedly connected to screw rods 1802. The external parts of the two screw rods 1802 are threadedly connected to moving rings 1803. The lower parts of the two moving rings 1803 are rotatably connected to adjustment plates 1804. The other ends of the two adjustment plates 1804 are rotatably connected to horizontal plates 1805. The lower part of the horizontal plate 1805 is rotatably connected to auxiliary rollers 1806.
[0028] When the reel body 19 is unwinding, the double-headed motor 1801 is activated, which drives the two screw rods 1802 fixed to the output end to rotate. The rotation of the two screw rods 1802 drives the two movable rings 1803 connected to the outer ends thereof to move relative to each other. The relative movement of the two movable rings 1803 further drives the relative movement of the two adjustment plates 1804 connected to the lower portion thereof. The movement of the two adjustment plates 1804 causes the horizontal plate 1805 connected to the other end thereof to move downward. The downward movement of the horizontal plate 1805 drives the auxiliary roller 1806 connected to the lower portion thereof to move downward, causing the auxiliary roller 1806 to contact the outside of the reel body 19. This facilitates the positioning of the yarn roll when the reel is unwinding, ensures that the yarn roll remains stable during the unwinding process, and does not slip or fall off due to vibration or other reasons, thereby avoiding damage to the yarn roll and improving production efficiency.
[0029] Working principle: When the reel body 19 needs to be replaced, first, start the first motor 5, the first motor 5 drives the gear 7 fixed at the output end to rotate, the gear 7 rotates and drives the external meshing rack plate 8 to move, the rack plate 8 moves and drives the upper fixed fixed rod 11 to move, the fixed rod 11 moves and drives the upper fixed positioning plate 12 to move, so that the positioning plate 12 is disengaged from the turntable 20, and then the reel body 19 is removed from the outside of the turntable 20. When installing a new reel, repeat the above steps to engage the positioning plate 12 with the turntable 20, so that the reel is easily replaced and solves the problem of the traditional reel replacement method that requires the operator to use tools such as a wrench or a screwdriver to manually loosen the fixing bolts or clamps at both ends of the reel. This operation method is simple and convenient, and improves work efficiency. During unwinding, by starting the double-headed motor 1801, the double-headed motor 1801 drives the two screw rods 1802 fixed at the output end to rotate, and the two screw rods 1802 rotate and drive the two movable rings 1803 connected by external threads to move relative to each other, and the two movable rings 1803 move relative to each other and drive the two adjusting plates 1804 connected by lower rotation to move relative to each other, and the two adjusting plates 1804 move and drive the horizontal plate 1805 connected by the other end to move downward, and the horizontal plate 1805 moves downward and drives the auxiliary roller 1806 connected by the lower rotation to move downward, so that the auxiliary roller 1806 is in contact with the outside of the drum body 19, so that the yarn roll can be limited when the drum is unwinding, and it can be ensured that the yarn roll remains stable during the unwinding process and will not slide or fall off due to vibration or other reasons, thereby avoiding damage to the yarn roll and improving production efficiency.
