Description

Technical Field

[0001] This utility model relates to the field of steel wire processing technology, specifically to a steel wire processing and winding device. Background Technology

[0002] Steel wire is one of the four major types of steel products: plates, pipes, profiles, and wires. It is a reprocessed product made from hot-rolled wire rods through cold drawing. The main processes in steel wire production include raw material selection, removal of iron oxide scale, drying, coating treatment, heat treatment, wire drawing, and plating treatment. During processing, steel wire needs to be wound and coiled using winding equipment, and then the wire coils are transferred to the warehouse for storage by trolley.

[0003] The utility model CN222877332U discloses a winding device for steel wire rope processing, including a base plate, a column, a first fixed plate, a second fixed plate, a first mounting plate and a second mounting plate fixedly connected to the top of the base plate, a guide roller slidably connected between the first fixed plate and the second fixed plate, a guide groove is provided on the outer side of the guide roller, and an adjustment component is provided inside the first fixed plate and the second fixed plate.

[0004] The above technical solution involves placing the two ends of the rope reel into the first and second mounting slots respectively, then passing the wire rope sequentially through the first and second guide rings, and then winding it through the guide groove on the outside of the guide roller. Finally, the wire rope is wound around the inside of the rope reel. The rotating component drives the rope reel to rotate between the first and second mounting plates, thereby achieving uniform winding of the wire rope, which improves the processing efficiency of the wire rope and significantly enhances the working efficiency of the winding equipment, avoiding resource waste. However, the wound wire is not tight. When it is not pressed and closed during winding, the wound wire is fluffy, occupies a lot of space, and cannot be collected tightly. Moreover, during winding, it cannot be continuously and evenly distributed for collection, and it is inconvenient to quickly disassemble and replace it after collection. Utility Model Content

[0005] The purpose of this invention is to provide a steel wire processing and winding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A steel wire processing and winding device includes a base plate, front support plates are symmetrically arranged at the front end of the upper surface of the base plate, a guide assembly is arranged between the two front support plates, rear support plates are symmetrically arranged at the rear end of the upper surface of the base plate, a drive assembly is arranged on the top of the side wall of one of the rear support plates, and a compaction assembly is arranged between the two rear support plates.

[0008] The guiding component includes a slide rail and a limiting block that is slidably inserted into the slide rail. The limiting block has a hinge seat at the top and a collar at the bottom. A T-slot is formed on the upper surface of the slide rail corresponding to the limiting block. A through slot is formed on the bottom of the slide rail corresponding to the collar. A connecting rod is rotatably connected to the hinge seat.

[0009] The drive assembly includes a motor and a rotating shaft connected to the motor output shaft via a coupling. The rotating shaft has a first conical tooth at one end near the motor and a swing arm at one end near the connecting rod. A connecting shaft is also provided on one side of the first conical tooth. A second conical tooth is provided on the connecting shaft at a position corresponding to the first conical tooth. The connecting shaft passes through one of the rear support plates. Several protrusions are provided on the outer wall of the connecting shaft. A winding roller is sleeved on the connecting shaft.

[0010] The compaction assembly includes a U-shaped plate and a compaction roller rotatably connected to the U-shaped plate. The bottom of the U-shaped plate is provided with several springs, and both ends of the U-shaped plate are provided with sliders. The rear support plate is provided with a groove corresponding to the slider.

[0011] Furthermore, the bottom of each of the front support plates is welded and fixed to the upper surface of the base plate, and the bottom of each of the rear support plates is welded and fixed to the upper surface of the base plate.

[0012] In this invention, both the front support plate and the rear support plate are welded to the base plate to increase the structural stability of the assembly.

[0013] Specifically, the two ends of the slide rail are fixedly connected to the top of the front support plate by screws, the width of the outer wall of the limiting block is adapted to the width of the inner wall of the T-slot, and several pulleys are provided on both sides of the limiting block. The pulleys are rotatably connected to the limiting block, and the outer wall of the pulley is tightly fitted to the inner wall of the T-slot.

[0014] In this invention, the limiting block is T-shaped and is inserted into the T-slot to restrict the range of motion of the limiting block. With the cooperation of multiple pulleys, the limiting block can move flexibly horizontally in the T-slot.

[0015] Furthermore, the top of the collar is welded and fixed to the bottom of the limiting block, the bottom of the hinge seat is welded and fixed to the top of the limiting block, the collar is slidably engaged with the through groove, one end of the connecting rod is rotatably connected to the hinge seat, and the other end of the connecting rod is rotatably connected to the end of the swing arm.

[0016] In this invention, the collar facilitates the passage of steel wires that need to be processed through the middle. The collar moves back and forth with the limit block, so that the steel wires are evenly spread on the winding roller. The connecting rod connects the hinge seat and the swing arm, so that the swing arm rotates and drives the limit block to move back and forth on the horizontal plane.

[0017] It should be noted that the motor is fixedly connected to the rear support plate by screws, the output shaft of the motor is coaxially connected to the rotating shaft, and symmetrical positioning blocks are provided on the rotating shaft. One positioning block is fixedly connected to the rear support plate by screws, and the other positioning block is fixedly connected to the base plate by screws. The rotating shaft is rotatably connected to the positioning blocks.

[0018] In this invention, the motor is electrically connected to an external power source via a wire. With the help of a control switch on the outer wall of the motor, the output shaft and the rotating shaft are connected via a connector. When the control switch is turned on, the output shaft rotates, which in turn drives the rotating shaft to rotate, thereby enabling the swing arm to rotate continuously. With the help of two positioning blocks, the position of the rotating shaft is restricted, providing a point of force to support the rotating shaft.

[0019] Furthermore, the second conical tooth is welded and fixed to the connecting shaft, the connecting shaft is rotatably connected to the rear support plate, and the connecting shaft is provided with positioning rings on both sides of the rear support plate, and the second conical tooth meshes with the first conical tooth.

[0020] In this invention, the connecting shaft is restricted to rotate on one of the rear support plates by the cooperation of two positioning rings, and the first conical tooth meshes with the second conical tooth. When the motor starts, the output shaft rotates, driving the rotating shaft to rotate synchronously with the connecting shaft, so as to realize the synchronous movement of the winding roller and the limiting block.

[0021] Furthermore, the winding roller has a slot at its end, and a groove is formed on the inner wall of the slot corresponding to the protrusion. The protrusions are evenly spaced, and the width of the outer wall of the protrusion matches the width of the inner wall of the groove. One end of the winding roller is provided with a limiting plate, and the other end of the winding roller is provided with a side baffle. The side baffle is inserted into the connecting shaft and is fixedly connected to the connecting shaft by a fixing bolt passing through the side baffle.

[0022] In this invention, the winding roller is connected to the connecting shaft via a slot, and the protrusion is connected to the groove. The winding roller and the connecting shaft rotate synchronously. The limiting plate restricts the position of the winding wire on the winding roller, and with the cooperation of the side baffle, it intercepts and protects the other end of the winding roller to prevent the winding wire in the middle from detaching from the winding roller. At the same time, with the cooperation of the side baffle, it prevents the winding roller from detaching from the connecting shaft. The fixing bolts can be removed and the side baffle can be taken out, making it convenient to disassemble and replace the winding roller.

[0023] It is worth noting that the compaction roller is rotatably connected to the U-shaped plate via a rotating shaft, the slider and the U-shaped plate are integrally formed, the width of the outer wall of the slider is adapted to the width of the inner wall of the groove, the length of the compaction roller is adapted to the length of the winding roller, the springs are evenly distributed, one end of the spring is bonded and fixed to the bottom of the U-shaped plate, and the other end is bonded and fixed to the base plate.

[0024] In this invention, the spring has elasticity and supports the compression roller close to the winding roller. The steel wire wound on the winding roller increases in size and the overall diameter increases. The compression roller compresses the spring and continuously compresses the wound steel wire. The slider and the groove slide together to achieve stable up and down movement of the U-shaped plate.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. This utility model combines a drive assembly with one of the rear support plates and a guide assembly with the front support plate. The motor on the drive assembly provides power, and the rotating shaft and the connecting shaft rotate synchronously under the meshing of the first and second conical teeth. The swing arm at the end of the rotating shaft is rotatably connected to the hinge seat on the limit block through a connecting rod. The rotation of the rotating shaft enables the limit block to move horizontally back and forth around the swing arm. The collar on the limit block guides the steel wire to move back and forth and wrap around the winding roller. With the cooperation of the compaction roller, the wound steel wire is tightly compacted and wound up for use under the cooperation of the spring and the U-shaped plate.

[0027] 2. This utility model features a slot that engages with the connecting shaft, with the protrusion and groove tightly interlocked. The winding roller is stably interlocked with the connecting shaft, and the position of the winding roller is fixed with the side baffle. A pulley is fitted on the limiting block to increase the flexibility of the limiting block moving on the slide rail. The fixing bolts on the side baffle can be removed for easy replacement of the winding roller, thus enabling continuous wire winding and coiling processing. Attached Figure Description

[0048] It should be noted that the drive assembly 2 includes a motor 20 and a rotating shaft 21 connected to the output shaft of the motor 20 via a coupling.

[0049] In this utility model, with the cooperation of the collar 511, it is convenient for the steel wire that needs to be processed to pass through the middle. The collar 511 moves back and forth with the limit block 51, so that the steel wire is evenly laid on the winding roller 3. The connecting rod 52 connects the hinge seat 512 and the swing arm 211, so that the swing arm 211 rotates and drives the limit block 51 to move back and forth on the horizontal plane.

Positioning rings are provided on both sides of the connecting shaft 22 located on the rear support plate 11. The second conical tooth 220 meshes with the first conical tooth 210.

[0051] In this utility model, the connecting shaft 22 is restricted to rotate on one of the rear support plates 11 with the cooperation of two positioning rings, and the first conical tooth 210 meshes with the second conical tooth 220. When the motor 20 starts, the output shaft rotates and drives the rotating shaft 21 to rotate synchronously with the connecting shaft 22, so as to realize the synchronous movement of the winding roller 3 and the limiting block 51.

[0052] Specifically, the connecting shaft 22 passes through one of the rear support plates 11. Several protrusions 221 are provided on the outer wall of the connecting shaft 22.

The springs 42 are evenly distributed. One end of the spring 42 is bonded and fixed to the bottom of the U-shaped plate 40, and the other end is bonded and fixed to the base plate 1.

[0056] In this utility model, the spring 42 has elasticity and supports the compression roller 41 close to the winding roller 3.

The slider 400 and the slide groove 110 slide together to realize the stable up and down movement of the U-shaped plate 40.

[0057] In this embodiment of the wire processing and winding equipment, the front support plate 10 and the rear support plate 11 are first fixed on the base plate 1. The limiting block 51 with the hinge seat 512 and the collar 511 is engaged with the T-slot 500 on the slide rail 50 through the pulley 510. The collar 511 passes through the through slot 501, and both ends of the slide rail 50 are combined and fixed with the front support plate 10. The motor 20 is fixed on one of the rear support plates 11. The rotating shaft 21 with the first conical tooth 210 and the swing arm 211 is rotatably engaged with the corresponding base plate 1 and rear support plate 11 through the positioning block. The rotating shaft 21 is connected to the output shaft of the motor 20 through a coupling. The connecting shaft 22 with a protrusion 221 is rotatably connected to one of the rear support plates 11 through a positioning ring.

The spring 42 is supported between the U-shaped plate 40 and the base plate 1.

[0058] The steel wire to be processed passes through the collar 511 and its top end is wound around one end of the winding roller 3. The control switch of the motor 20 is started, and the output shaft drives the rotating shaft 21 and the connecting shaft 22 to rotate synchronously. The diameter of the first conical tooth 210 is larger than the diameter of the second conical tooth 220, so that the rotating shaft 21 rotates once and drives the connecting shaft 22 to rotate multiple times. The limit block 51 moves horizontally back and forth, guiding the steel wire to wind multiple times on the winding roller 3. It also cooperates with the compaction roller 41 to press and adhere to increase the tightness of the steel wire winding, reduce the space occupied, and stably carry out the steel wire winding and winding. After the winding is completed, when it is necessary to disassemble the winding roller 3, the fixing bolt is removed from the side baffle 32 and the side baffle 32 is taken out, which makes it convenient to take out the winding roller 3 after the steel wire is wound and replace it, which helps the next steel wire winding and winding.
