Description

Technical Field

[0001] This utility model relates to the field of cable reel technology, and in particular to a wear-resistant cable guide wheel device for cable reels. Background Technology

[0002] A cable reel is a device specifically designed for neatly organizing and storing cables. It uses a rotating shaft to wind data cables, industrial cables, etc., preventing tangling and wear. Its core components include a winding roller, a drive mechanism, and a guide assembly. The materials are mostly engineering plastics or metal alloys, combining lightweight and durability. It can be operated manually or electrically, significantly improving cable portability and lifespan, and is suitable for home, industrial, and mobile work scenarios.

[0003] The guide wheel forcibly constrains the wire path, ensuring that it moves back and forth at a uniform speed along the axis of the winding roller, achieving uniform wire laying, avoiding overlapping and tangling, and reducing wire friction damage. However, direct dry friction between the wheel and the wire can lead to scratches and tears on the wire surface, accelerated aging of the insulation layer, and burrs caused by wear of the metal wheel groove, which can further cut the cable. To address these issues, we propose a wear-resistant wire laying guide wheel device for winding machines. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background art by proposing a wear-resistant cable guide wheel device for cable reels.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant cable guide wheel device for a cable reel, comprising a winding structure, a guiding structure, and a wear-resistant structure.

[0006] The winding structure includes a support frame, a motor located at the upper end of the support frame, and a winding roller rotatably installed inside the support frame.

[0007] The guide structure includes side frames symmetrically distributed at the front end of the support frame, a reciprocating screw rotatably installed inside the side frame, a reciprocating nut sleeved on the outer wall of the reciprocating screw, and a stroke plate located at the lower end of the reciprocating nut.

[0008] The wear-resistant structure includes a guide wheel fixed to the upper end of the reciprocating nut, an inner ring located at the center of the guide wheel, a support rod fixed between the inner ring and the guide wheel in a ring array, balls rotatably installed inside the inner ring in a ring array, a graphite block attached to the outer wall of the balls, and a positioning seat located at one end of the graphite block.

[0009] Preferably, the motor output end is provided with a first gear, and the outer wall of the roller is sleeved with a second gear that meshes with the first gear. When the first gear and the second gear mesh, the rotational force of the motor output end is applied to the roller.

[0010] Preferably, limit wheels are fitted onto the outer walls of both ends of the roller, and a guide wheel frame is provided at one end of the travel plate, with pulleys rotatably installed inside the guide wheel frame. The limit wheels restrict the wire wound on the outer wall of the roller, and the pulleys plan the path of the wire groove.

[0011] Preferably, a second sprocket is sleeved on the outer wall of the reciprocating screw, and a first sprocket is provided at the motor output end. Both the first and second sprockets are sleeved on their outer walls with chains. The first and second sprockets are linked by the chains, and the rotational force of the motor output end is applied to the reciprocating screw.

[0012] Preferably, a guide rod is provided between the side frames, and a sliding sleeve is embedded inside the stroke plate and slidably fitted onto the outer wall of the guide rod. The stroke plate slides on the outer wall of the guide rod via the sliding sleeve, providing lateral sliding guidance for the stroke plate and the reciprocating nut.

[0013] Preferably, the inner wall of the guide ring is provided with positioning blocks arranged in a ring array, and a spring is provided between the positioning blocks and the positioning seat. The positioning blocks and the positioning seat are elastically installed by the spring, so that during the wear process of the graphite block, the elastic force of the spring always rolls the outer wall of the iron ring ball.

[0014] Preferably, the outer wall of the positioning seat is provided with a positioning cylinder, and one end of the positioning block is provided with a positioning rod that is slidably inserted into the positioning cylinder. Both the positioning rod and the positioning cylinder are located inside the spring. During the extension and retraction of the spring, the positioning cylinder slides outside the positioning rod, guiding the spring and preventing it from shifting outward.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model relates to a winding roller for winding wire. During the winding process, a reciprocating screw drives a reciprocating nut to move laterally back and forth, which in turn drives a guide wheel to force the winding path of the wire, thereby evenly winding the wire onto the outer wall of the winding roller. The inner wall of the guide wheel is provided with balls arranged in a ring array that roll and adhere to the outer wall of the wire, reducing wear on the wire. When the balls rotate, they rub against the graphite blocks, and the graphite releases micro-powder as the balls rotate. The graphite powder adheres to the balls, forming a solid lubricating film, which reduces the coefficient of friction and prevents scratches on the wire surface. Furthermore, the ring array of rotating balls disperses pressure, preventing abrasive wear from the metal wheel groove, reducing winding resistance, reducing motor load, and extending equipment life.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-5 As shown, the present invention proposes a wear-resistant cable guide wheel device for a cable reel, comprising a winding structure 100, a guiding structure 200, and a wear-resistant structure 300.

[0027] The winding structure 100 includes a support frame 101, a motor 103 located at the upper end of the support frame 101, and a winding roller 102 rotatably installed inside the support frame 101;

[0028] The guide structure 200 includes a side frame 201 symmetrically distributed at the front end of the support frame 101, a reciprocating screw 205 rotatably installed inside the side frame 201, a reciprocating nut 209 sleeved on the outer wall of the reciprocating screw 205, and a stroke plate 208 located at the lower end of the reciprocating nut 209.

[0029] The wear-resistant structure 300 includes a guide wheel 301 fixed to the upper end of the reciprocating nut 209, an inner ring 302 located at the center of the guide wheel 301, a support rod 310 fixed between the inner ring 302 and the guide wheel 301 in a ring array, balls 303 rotatably installed inside the inner ring 302 in a ring array, a graphite block 309 attached to the outer wall of the ball 303, and a positioning seat 308 located at one end of the graphite block 309.

[0030] The output end of the motor 103 is provided with a gear 104, and the outer wall of the roller 102 is fitted with a gear 105 that meshes with the gear 104.

[0031] Limiting wheels 107 are fitted onto the outer walls of both ends of the roller 102. A guide wheel frame 106 is provided at one end of the stroke plate 208. A pulley 108 is rotatably installed inside the guide wheel frame 106.

[0032] A sprocket 204 is sleeved on the outer wall of the reciprocating screw 205, and a sprocket 202 is provided at the output end of the motor 103. Both the outer walls of the sprocket 202 and the sprocket 204 are sleeved with chains 203.

[0033] A guide rod 206 is provided between the side frames 201, and a sliding sleeve 207 is embedded in the stroke plate 208 and slidably sleeved to the outer wall of the guide rod 206;

[0034] The inner wall of the guide ring is provided with positioning blocks 305 arranged in a ring array, and a spring 304 is provided between the positioning blocks 305 and the positioning seat 308.

[0035] The outer wall of the positioning seat 308 is provided with a positioning cylinder 307, and one end of the positioning block 305 is provided with a positioning rod 306 that is slidably inserted into the positioning cylinder 307. Both the positioning rod 306 and the positioning cylinder 307 are located inside the spring 304.

[0036] Based on the implementation steps of Embodiment 1: Start the motor 103, and drive the winding roller 102 to rotate and wind the wire through the meshing of gear 104 and gear 205. Simultaneously, the output sprocket 1 202 of the motor 103 drives the sprocket 2 204 through the chain 203, so that the reciprocating screw rotates at a fixed speed ratio, such as the screw rotating 0.2 turns for every 1 revolution of the winding roller 102. The double sprockets precisely control the wire density and avoid the slippage problem of traditional belt drive. When the reciprocating screw 205 rotates, it pushes the reciprocating nut 209 to drive the stroke plate 208 to move laterally along the guide rod 206. The guide wheel 301 fixed on the reciprocating nut 209 moves back and forth accordingly, forcing the wire to be evenly wound on the surface of the winding roller 102 along the set path.

[0037] When the wire passes through the guide wheel 301, the pressure drives the ball 303 to roll under the constraint of the annular array support rod 310. The ball 303 and the graphite block 309 rub against each other to generate micro powder, forming a solid lubricating film that adheres to the surface of the ball 303. The graphite block 309 elastically presses the ball 303 through the positioning seat 308 and the spring 304. After wear, the gap is automatically compensated to ensure lifelong lubrication. The sliding sleeve 207 outside the guide rod 206 is made of oil-impregnated sintered copper material to reduce the friction of the stroke plate 208.

[0038] The limiting wheel 107 constrains the winding width of the wire, the pulley 108 pre-guides to reduce the wire deflection angle entering the guide wheel 301, the positioning cylinder 307 and the positioning rod 306 form a spring 304 guiding mechanism to prevent the spring 304 from bending laterally and causing uneven pressure on the graphite block 309, the ball 303 converts sliding friction into rolling friction, the wire surface pressure is distributed to multiple contact points, the unit pressure is reduced and the wire surface wear is reduced, completely eliminating the risk of skin breakage and aging;

[0039] Graphite powder continuously fills the gap between the ball 303 and the inner ring 302, avoiding direct metal-to-metal contact, reducing rolling resistance, decreasing the load current of the motor 103, and ensuring the continuous effectiveness of the graphite through the preload of the spring 304. The ball 303 is made of GCr15 bearing steel, which is an improvement over traditional copper wheels. By replacing sliding friction with rolling friction, dynamic self-lubrication of graphite, and compensation by the spring 304, it solves the problems of wire damage, equipment wear, and high energy consumption caused by dry friction of the guide wheel 301. It is suitable for high-frequency, large-diameter industrial scenarios, such as ship cable winding and unwinding, and power supply line storage in mining equipment.

[0040] The above specific embodiments are merely several preferred embodiments of this utility model.
