Description

Technical Field

[0001] This utility model relates to the field of blanket processing technology, specifically to a winding device for blanket processing that can prevent loosening. Background Technology

[0002] Blankets are a type of product with heat-insulating properties and excellent warmth retention. In the final stage of blanket weaving and production, in order to optimize storage space utilization and improve logistics efficiency, it is usually necessary to use a corresponding winding mechanism to efficiently roll up the originally flat, large-format blankets into compact cylindrical blanket rolls for subsequent logistics transportation.

[0003] In the traditional blanket winding process, the operator manually inserts one end of the blanket into a slot inside the drum as the drum rotates. The blanket is then wound onto the outer wall of the drum. However, due to the limited functionality of the drum structure, the inner diameter of the slot cannot be adjusted for different blanket thicknesses. Consequently, for blankets that are too thick or too thin, the slot cannot secure the side end, preventing proper winding. This necessitates disassembling and replacing the drum, impacting the efficiency of the blanket winding process. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a non-loosening winding device for blanket processing. This solves the problem that current winding mechanisms require the operator to manually insert one end of the blanket into a slot inside the roll when rotating and winding the blanket. As the roll rotates, the blanket is wound onto the outer wall of the roll. However, due to the limited functionality of the roll structure, the inner diameter of the slot cannot be adjusted for different blanket specifications and thicknesses. Consequently, for blankets that are too thick or too thin, the slot cannot secure the side end of the blanket, resulting in the blanket not being able to be wound properly. This necessitates the operator to disassemble and replace the roll, affecting the efficiency of blanket winding operations.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a winding device for processing blankets that can prevent loosening is designed, including a mounting frame, a rotating plate is rotatably mounted on the inner side of the mounting frame, a fixing frame is vertically fixed at the middle of the side of the rotating plate, and an abutment mechanism is provided on the other side of the mounting frame.

[0006] The mounting frame is movably equipped with pressure rollers on both sides of its exterior, and the fixed frame is equipped with an adjustment mechanism inside, which is connected to the pressure rollers in a driving connection.

[0007] The mounting frame is provided with clamping mechanisms at both ends of its outer side, and the clamping mechanisms and the adjusting mechanisms are connected by a transmission.

[0008] Preferably, the adjusting mechanism includes a bidirectional lead screw, which is rotatably mounted inside the fixed frame via bearings. Both sides of the bidirectional lead screw are threadedly connected to transmission sleeves, and a transmission block is fixedly mounted on the outer side of each transmission sleeve. Limiting grooves are vertically formed at both ends of the side of the fixed frame, and the transmission blocks are slidably mounted inside the limiting grooves.

[0009] Preferably, connecting frames are slidably mounted on both ends of the side surface of the fixed frame, and the top of the side of the transmission block is fixedly connected to the outer wall of the connecting frame. The top of the side of the pressing roller is fixedly connected to the outer wall of the connecting frame. A fixed rod is vertically rotatably mounted on the bottom middle of the fixed frame via a bearing, and the top of the fixed rod is fixedly connected to the bottom of the bidirectional lead screw. A transmission frame is fixedly mounted on the bottom of the fixed rod. A second servo motor is fixedly mounted on the bottom middle of the inner side of the mounting frame, and a rotating block is fixedly mounted on the top of the transmission shaft of the second servo motor. An abutment block is fixedly mounted on the top surface of the rotating block, and the abutment block is slidably inserted into the inside of the transmission frame.

[0010] Preferably, the abutting mechanism includes a drive turntable, a first servo motor is fixedly installed at the middle of the side of the fixed frame, a connecting rod is fixedly installed on the side of the transmission shaft of the first servo motor through a coupling, the end of the connecting rod away from the rotating plate is fixedly sleeved onto the drive turntable, and abutting slots are vertically opened at both ends of the side of the drive turntable.

[0011] Preferably, the clamping mechanism includes a limiting roller and a pushing spring. Fixed plates are slidably mounted on both ends of the outer side of the mounting frame. A hollow tube is vertically fixedly mounted on both ends of the side of each fixed plate. An extrusion plate is slidably mounted inside each hollow tube. A movable rod is fixedly mounted at the bottom of each extrusion plate. A pushing spring is movably arranged inside each hollow tube, with its two ends movably attached to the outer wall of the extrusion plate and the inner wall of the hollow tube, respectively. A lifting plate is fixedly mounted between the top ends of every two sets of movable rods. A support plate is vertically fixedly mounted on both ends of the side of each lifting plate. A limiting roller is rotatably mounted between the sides of every two sets of support plates.

[0012] Preferably, a transmission frame is fixedly sleeved at one end of the outer side of the pressing roller near the rotating plate, and a transmission rod is horizontally fixedly installed at the top side of each transmission frame, and the transmission rod is slidably inserted into the inside of the side of the mounting frame. A sliding plate is fixedly installed at the top side of each transmission rod, and the top side of the sliding plate is fixedly connected to the outer wall of the fixed plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model features a fixed frame rotatably mounted inside the mounting frame, and a bidirectional lead screw mounted inside the fixed frame. The bidirectional lead screw and the transmission frame are rotatably connected via the fixed frame. When the second servo motor starts, it drives a rotating block and its top abutting block to rotate. The abutting block's action on the transmission frame causes the transmission frame to rotate synchronously, which in turn drives the bidirectional lead screw to rotate synchronously within the fixed frame. The rotational transmission action of the bidirectional lead screw on its outer two ends of the transmission sleeves causes the two sets of transmission sleeves to rotate synchronously vertically towards each other within the fixed frame. Alternatively, they can move relative to each other, thus providing two sets of clamping rollers to move synchronously vertically towards each other or relative to each other. Adjusting the distance between the two sets of clamping rollers, after the clamping rollers are moved into the abutment slots inside the drive turntable, the drive of the first servo motor can provide the drive turntable with the corresponding rotational driving force. Combined with the abutment action of the abutment slots on the clamping rollers, the side ends of the clamping rollers can clamp the blanket to be wound from both the top and bottom sides. While adjusting the clamping applicability of different specifications of blankets, the clamping rollers can automatically wind the blankets to the outside of the clamping rollers after rotation, thereby improving the efficiency of blanket winding processing.

[0015] 2. This utility model connects a fixed plate to the outside of the pressure roller by combining a transmission frame and a transmission rod. After setting the limiting roller outside the pressure roller, the position of the limiting roller can be adjusted synchronously after the position of the pressure roller is adjusted. This ensures that the limiting roller is always outside the pressure roller. At the same time, the pushing spring inside the hollow tube outside the fixed plate provides a corresponding pushing force to the extrusion plate and the limiting roller. When the pressure roller rotates and winds the blanket, as the blanket is continuously wrapped around the outside of the pressure roller, the blanket can abut against the limiting roller. This ensures that while the limiting roller moves outward, its outer wall always remains in contact with the outer wall of the blanket, providing a limiting force during the blanket winding process. This prevents the blanket from coming apart and loosening during winding, and improves the tightness of the blanket winding. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A winding device for preventing loosening in blanket processing, see [link to example]. Figures 1 to 5 A rotating plate 11 is rotatably mounted on the inner side of the mounting frame 1. A fixed frame 12 is vertically fixedly mounted on the middle of the side of the rotating plate 11. A connecting frame 23 is slidably mounted on both ends of the side of the fixed frame 12. The top of the side of the transmission block 22 is fixedly connected to the outer wall of the connecting frame 23. The top of the side of the pressure roller 24 is fixedly connected to the outer wall of the connecting frame 23. A fixed rod 25 is vertically rotatably mounted on the middle of the bottom of the fixed frame 12 through a bearing. The top of the fixed rod 25 is fixedly connected to the bottom of the bidirectional lead screw 2. A transmission frame 26 is fixedly mounted on the bottom of the fixed rod 25. A second servo motor 17 is fixedly mounted on the middle of the bottom of the inner side of the mounting frame 1. A rotating block 27 is fixedly mounted on the top of the transmission shaft of the second servo motor 17. An abutment block 28 is fixedly mounted on the top surface of the rotating block 27. The abutment block 28 is slidably inserted into the inside of the transmission frame 26.

[0027] When the blanket needs to be wound, under the reset rotation control of the first servo motor 13 by the external PLC controller, the drive turntable 15 and the rotating plate 11 are driven to return to their original positions. At this time, the transmission frame 26 is slidably inserted into the outer wall of the abutment block 28. The servo motor is turned on by the external controller, so that it runs and provides the corresponding rotation driving force to the rotating block 27. This allows the rotating block 27 to drive the abutment block 28 to rotate inside the transmission frame 26. Under the abutment action of the abutment block 28 on the transmission frame 26, the transmission frame 26 can be driven to rotate synchronously at the bottom of the fixed frame 12. Combined with the connecting transmission action of the fixed rod 25, the bidirectional lead screw 2 inside the fixed frame 12 is provided with rotation driving force. When the drive turntable 15 and the rotating plate 11 rotate under the driving action of the first servo motor 13, the transmission frame 26 can slide away from the outside of the abutment block 28 synchronously. This ensures that when the fixed frame 12 rotates, the drive structure will not rotate synchronously and there will be mutual entanglement between the control lines.

[0028] For details, see Figures 1 to 5 The mounting frame 1 has pressure rollers 24 movably installed on both sides of the outside. The fixed frame 12 has a bidirectional lead screw 2 rotatably installed inside the frame via bearings. The bidirectional lead screw 2 has threads with opposite helical directions on both sides of its outer side with its center point as the axis of symmetry. The two sides of the bidirectional lead screw 2 are movably connected to the transmission sleeves 21 via threads. The inner side of the two sets of transmission sleeves 21 has threads that match the helical direction of the outer side of the bidirectional lead screw 2. The outer side of each transmission sleeve 21 is fixedly installed with a transmission block 22. The fixed frame 12 has vertical limit grooves 29 at both ends of its side, and the transmission block 22 is slidably installed inside the limit grooves 29.

[0029] When the bidirectional lead screw 2 rotates synchronously inside the fixed frame 12 under the rotational drive of the transmission frame 26, combined with the rotational transmission of the transmission sleeve 21 by the bidirectional lead screw 2 and the guiding and limiting effect of the transmission block 22 by the limiting slide groove 29, the two sets of transmission sleeves 21 can move towards each other synchronously inside the transmission frame 26, thereby synchronously driving the two sets of pressing rollers 24 to move vertically towards each other. This allows the pressing rollers 24 to move vertically into the abutment slots 16 on both sides inside the drive turntable 15 while the spacing is adjusted, until the outer wall of the pressing rollers 24 is fully and tightly attached to the upper and lower sides of the blanket to be wound, thus fully clamping the side ends of the blanket.

[0030] Further, see Figures 1 to 5A first servo motor 13 is fixedly installed at the middle of the side of the fixed frame 12. An encoder is set at the end of the motor shaft of the first servo motor 13, which can provide real-time feedback of rotor position, speed and direction information. Combined with the connection and control of the external PLC controller, the rotation position of the first servo motor 13 can be reset after the first servo motor 13 is driven to run, thereby driving the rotating plate 11 to reset and rotate, which facilitates the subsequent drive adjustment of the bidirectional lead screw 2. A connecting rod 14 is fixedly installed on the side of the transmission shaft of the first servo motor 13 through a coupling. The end of the connecting rod 14 away from the rotating plate 11 is fixedly sleeved with the drive turntable 15. Both ends of the drive turntable 15 are vertically provided with abutment slots 16, and the pressure roller 24 and the abutment slots 16 are in the same vertical position.

[0031] After the pressure roller 24 clamps the side end of the blanket tightly, the first servo motor 13 is started by the external controller, which drives the drive turntable 15 to rotate synchronously. Then, under the abutting action of the abutting slot 16 on the pressure roller 24, the pressure roller 24, its side fixed frame 12 and rotating plate 11 can be driven to rotate synchronously. As the pressure roller 24 rotates, it winds the blanket clamped on its side end, and winds the originally flat blanket into a cylinder and wraps it around the outer wall of the pressure roller 24, realizing the automatic winding process of the blanket.

[0032] It is worth noting that, see Figures 1 to 5 A fixed plate 33 is slidably installed at both ends of the outer side of the mounting frame 1. A hollow tube 37 is vertically fixedly installed at both ends of the side of each fixed plate 33. An extrusion plate 4 is slidably installed inside each hollow tube 37. A movable rod 38 is fixedly installed at the bottom of each extrusion plate 4. The movable rod 38 is slidably inserted into the hollow tube 37 and the fixed plate 33. A push spring 41 is movably installed inside each hollow tube 37. The two ends of the push spring 41 are movably attached to the outer wall of the extrusion plate 4 and the inner wall of the hollow tube 37, respectively. A lifting plate 34 is fixedly installed between the top ends of the sides of every two sets of movable rods 38. A support plate 35 is vertically fixedly installed at both ends of the sides of each lifting plate 34. A limiting roller 36 is rotatably installed between the sides of every two sets of support plates 35. The limiting roller 36 is located outside the pressing roller 24.

[0033] A transmission frame 3 is fixedly sleeved on the outer side of the pressure roller 24 near the rotating plate 11. A transmission rod 31 is horizontally fixedly installed on the top side of each transmission frame 3, and the transmission rod 31 is slidably inserted into the inside of the side of the mounting frame 1. A sliding plate 32 is fixedly installed on the top side of each transmission rod 31, and the top side of the sliding plate 32 is fixedly connected to the outer wall of the fixed plate 33.

[0034] As the pressure roller 24 rotates and winds the blanket into a cylinder, the blanket wraps around the outside of the pressure roller 24. At the same time, the blanket can abut against the limiting roller 36, causing the limiting roller 36 to move outward towards the outside of the pressure roller 24. Under the reverse pushing action provided by the push spring 41, its outer wall always remains in contact with the outer wall of the blanket, providing a limiting force during the blanket winding process. This ensures that the blankets are tightly attached to each other during the winding process and will not become too loose. Subsequently, after the blanket is wound, it is pushed from the side of the blanket roll and moved out from the outside of the two sets of clamping rollers. After the limiting roller 36 loses the abutment force of the blanket roll, it automatically returns to its position under the restoring pushing force provided by the push spring 41, so that the limiting roller 36 can continue to be used for subsequent pressing and preventing loosening.
