Description

Technical Field

[0001] This invention relates to the field of cable reel devices, specifically a height-adjustable guide device for loading cables onto a cable reel. Background Technology

[0002] During the production, laying, and transportation of cables, they are usually collected and wound onto take-up reels for storage, transfer, and subsequent use. During the cable loading process, the take-up reel generally rotates continuously, causing the cable to wind layer by layer onto the surface of the reel along its axial direction. To ensure that the cable is wound neatly onto the take-up reel, a guide device is usually installed between the take-up reel and the cable conveying equipment. The guide structure restricts and guides the direction of cable movement, allowing the cable to enter the take-up reel along a predetermined path. Existing cable take-up devices typically have a guide structure that moves the cable axially along the reel to prevent it from continuously accumulating in the same position. However, in actual cable loading, different reels and cables require different winding heights. The guide height of some existing guide devices is usually fixed, or requires manual adjustment by the operator based on the actual loading height. When changing to a different reel, the working position of the guide structure often needs to be redefined, which is cumbersome. Furthermore, manual adjustment makes it difficult to ensure consistent adjustment accuracy between different reels, thus reducing the adaptability of the cable loading equipment to different winding conditions. Therefore, this application proposes a height-adjustable guide device for cable take-up reels. Summary of the Invention

[0003] The purpose of this invention is to provide a height-adjustable guide device for cable reel loading, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a height-adjustable guide device for cable winding onto a cable reel, comprising a reel frame, a cable reel rotatably mounted on the surface of the reel frame, a device frame disposed on the right side of the reel frame, an extension frame fixedly mounted on the upper end of the device frame, a guide roller rotatably mounted inside the extension frame, a pressing rod slidably mounted on the surface of the guide roller, the pressing rod being used to guide the cable bundle delivered to the cable reel, so that the cable bundle can be neatly wound around the surface of the cable reel under the guidance of the pressing rod, the pressing rod being able to reciprocate along the axial direction of the guide roller, so that the entry position of the cable bundle can change accordingly with the rotation of the cable reel, thereby gradually arranging the cable bundle along the axial direction of the cable reel and forming a relatively neat winding layer, and a guide ring slidably mounted on the surface of the extension frame, the guide ring being used to guide the position of the cable bundle entering the guide roller.

[0005] As a further embodiment of the present invention, a spiral sleeve is rotatably installed inside the guide roller, a rectangular sliding hole is opened on the surface of the guide roller, a protrusion is fixedly installed on the surface of the pressing rod, the protrusion passes through the rectangular sliding hole on the surface of the guide roller and extends into the threaded groove on the surface of the spiral sleeve, a central rod is inserted inside the spiral sleeve, one end of the central rod away from the spiral sleeve extends to the outside of the extension frame, and a steering handle is sleeved on the surface of the central rod.

[0006] As a further embodiment of the present invention, the steering handle is rotatable relative to the central rod and can drive the central rod to rotate synchronously through rotation. A limit block is fixedly installed on the surface of the extension frame, and a limit groove is formed on the surface of the steering handle. When the steering handle rotates to the position corresponding to the limit groove and the limit block, the steering handle is pushed to move along the axial direction of the central rod, and the limit groove is sleeved on the outside of the limit block, thereby restricting the steering handle and the central rod from continuing to rotate.

[0007] As a further embodiment of the present invention, a limiting ring is fixedly installed inside the guide roller. The limiting ring is sleeved on the outside of the central rod and is used to limit the position of the central rod inside the guide roller, so that the central rod can maintain the installation position corresponding to the spiral sleeve. By setting the limiting ring to limit the central rod, the central rod can maintain the installation position corresponding to the spiral sleeve, avoiding the positional deviation of the central rod during the rotation of the guide roller, thereby ensuring the stable transmission cooperation between the guide block and the spiral tube, and improving the reliability of height adjustment and locking actions.

[0008] As a further embodiment of the present invention, a guide tube is provided inside the spiral sleeve, and a transmission cylinder is fixedly installed at one end of the limiting ring near the guide tube. The guide tube is fixedly connected to the transmission cylinder so that the guide tube can remain relatively fixed with the transmission cylinder. A spiral tube is slidably installed inside the guide tube, and one end of the central rod away from the limiting ring passes through the interior of the spiral tube so that the central rod can form a transmission engagement with the spiral tube.

[0009] As a further embodiment of the present invention, a guide block is fixedly installed on the surface of the central rod. The guide block passes through the spiral groove on the surface of the spiral tube. When the central rod rotates, the guide block can move along the spiral groove on the surface of the spiral tube. Through the cooperation between the spiral groove and the guide block, the spiral tube moves axially relative to the guide tube. By setting the guide block and cooperating with the spiral groove on the surface of the spiral tube, the rotational motion of the central rod can be converted into the axial movement of the spiral tube along the guide tube, thereby facilitating the adjustment of the distance between the spiral tube and the locking cylinder and providing a stable transmission effect for the preset adjustment of the winding height of the pressing rod.

[0010] As a further embodiment of the present invention, a locking cylinder is sleeved inside the transmission cylinder. After the spiral tube moves a certain distance along the axial direction, it contacts the end of the locking cylinder and pushes the locking cylinder to move synchronously along the axial direction. The locking cylinder is connected to the central rod by a return spring, so that after the locking cylinder is pushed by the spiral tube and moves, it can return to its original position by the elastic action of the return spring. Multiple pushing blocks are slidably installed inside the transmission cylinder along the circumference. Multiple transmission blocks are fixedly installed on the surface of the limiting ring along the circumference. A locking block is provided between each two adjacent transmission blocks, so that the multiple locking blocks can be located between adjacent transmission blocks and move in the corresponding direction.

[0011] As a further aspect of the present invention, the spiral sleeve is provided with multiple locking grooves at one end near the limiting ring. The multiple locking grooves are respectively positioned corresponding to multiple locking blocks, so that after the multiple locking blocks move away from each other, their ends can extend into the corresponding locking grooves. By setting locking grooves corresponding to multiple locking blocks and allowing the locking blocks to move outward and extend into the corresponding locking grooves, the spiral sleeve can be reliably engaged and limited, preventing the spiral sleeve from continuing to rotate after reaching the predetermined winding height. This ensures that the pressing rod can be stably maintained in the corresponding guide position, improving the accuracy of winding height control.

[0012] As a further embodiment of the present invention, a plurality of guide blocks are fixedly installed on the surface of the locking cylinder along the circumferential direction. A guide groove is provided on the side of the pushing block near the locking cylinder, and the guide block is correspondingly inserted into the guide groove, so that when the locking cylinder moves along the axial direction, the pushing block can be driven to move synchronously through the cooperation of the guide block and the guide groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting a center rod, a steering handle, a guide tube, a spiral tube, and a guide block, rotates the steering handle to drive the center rod to rotate, so that the guide block engages with the spiral groove on the surface of the spiral tube, thereby adjusting the initial distance between the spiral tube and the locking cylinder. The adjustment position is corresponding to the annular scale on the surface of the steering handle, so that the device can pre-set the guide height of the pressing rod according to the winding height of different coils, improving the adaptability of the device to different winding conditions, and at the same time facilitating repeated adjustments by the operator; 2. This invention utilizes the effect of increasing the winding height of the wire harness on the pressing rod, enabling the pressing rod to deflect at a corresponding angle as the winding height increases, and driving the guide roller to rotate synchronously. This, in turn, causes the limiting ring, transmission cylinder, guide tube, and spiral tube to move accordingly. Since the center rod remains fixed after adjustment, the spiral tube can gradually approach the locking cylinder under the guidance of the guide block. This allows the pressing rod to change its working state according to the actual winding height of the wire harness, avoiding mismatch in the guide angle after the winding height of the wire harness increases due to the guide position remaining fixed for a long time. 3. This invention, by setting a locking cylinder, a pushing block, a locking block, a guide block, a guide groove, and a locking groove at the end of the spiral sleeve, allows the spiral tube to move to a predetermined position as the winding height of the wire harness increases. The spiral tube then pushes the locking cylinder to move, and the locking cylinder, through the guide block and guide groove, drives the pushing block to move. This causes the inclined surface of the pushing block to push the locking block to move radially outward, and the end of the locking block to extend into the locking groove at the end of the spiral sleeve. This restricts the spiral sleeve from continuing to rotate, stopping the pressing rod at a predetermined guide position. This achieves mechanical limiting of the winding height of the wire harness, preventing the auxiliary motor from continuing to drive after reaching the predetermined winding state, thus avoiding further movement of the guide structure.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figures 1-3 A height-adjustable guide device for cable winding onto a cable reel includes a reel frame 1. A cable reel 2 is rotatably mounted on the surface of the reel frame 1. A device frame 4 is located on the right side of the reel frame 1. An extension frame 3 is fixedly mounted on the upper end of the device frame 4. A guide roller 101 is rotatably mounted inside the extension frame 3. A pressing rod 104 is slidably mounted on the surface of the guide roller 101. The pressing rod 104 is used to guide the cable bundle delivered to the cable reel 2, so that the cable bundle can be neatly wound around the surface of the cable reel 2 under the guidance of the pressing rod 104. The pressing rod 104 can move along... The guide roller 101 moves axially back and forth so that the entry position of the wire harness can change accordingly with the rotation of the wire reel 2, thereby gradually arranging the wire harness along the axial direction of the wire reel 2 and forming a relatively neat winding layer. As the number of winding layers of the wire harness on the surface of the wire reel 2 gradually increases, the winding height of the wire harness in the radial direction increases accordingly, causing the relative height of the wire harness when entering the wire reel 2 to change, and causing the pressing rod 104 to produce a corresponding angle change relative to the winding position of the wire reel 2, so that the pressing rod 104 can adapt to the change in the winding height of the wire harness. A guide ring 102 is slidably mounted on the surface of the extension frame 3. The guide ring 102 is used to guide the position of the wire harness entering the guide roller 101. The wire harness passes through the guide ring 102 and the guide hole provided at the end of the pressing rod 104 in sequence, so that the wire harness is continuously guided and constrained before entering the wire reel 2, thereby reducing the possibility of the wire harness swinging, deviating or tangling during the conveying and winding process, enabling the wire harness to enter the wire reel 2 along a relatively stable path, and improving the winding regularity of the wire harness on the surface of the wire reel 2.

[0018] like Figures 2-4 As shown, an auxiliary motor 103 is fixedly mounted on the surface of the extension frame 3, and a spiral sleeve 107 is rotatably mounted inside the guide roller 101. The output end of the auxiliary motor 103 is fixedly connected to the spiral sleeve 107 so as to drive the spiral sleeve 107 to rotate. The auxiliary motor 103 is a servo motor with self-finding encoding. When the spiral sleeve 107 rotates to the preset motion limit and can no longer rotate, the auxiliary motor 103 can stop running or try to rotate in the opposite direction, thereby reducing the possibility of damage to the pressing rod 104 and its transmission structure caused by the continuous force rotation of the spiral sleeve 107. The surface of the guide roller 101 is provided with a rectangular sliding hole, and a protrusion is fixedly installed on the surface of the pressing rod 104. The protrusion passes through the rectangular sliding hole on the surface of the guide roller 101 and extends into the threaded groove on the surface of the spiral sleeve 107. When the spiral sleeve 107 rotates, it can drive the pressing rod 104 to move back and forth along the axial direction of the guide roller 101 through the cooperation between the threaded groove and the protrusion, thereby changing the guiding position of the pressing rod 104 on the wire harness, so that the wire harness can be gradually arranged along the axial direction during the winding process of the wire spool 2. Since the pressing rod 104 is slidably mounted on the surface of the guide roller 101, and the pressing rod 104 is always in contact with the wire harness on the surface of the wire spool 2 during operation, when the spiral sleeve 107 drives the pressing rod 104 to move axially along the guide roller 101, it can change its guiding position while maintaining the guiding and constraining effect of the pressing rod 104 on the wire harness, so that the pressing rod 104 can adapt to the changes in the winding position of the wire harness on the surface of the wire spool 2. A central rod 106 is inserted inside the spiral sleeve 107. The end of the central rod 106 away from the spiral sleeve 107 extends to the outside of the extension frame 3. A steering handle 105 is fitted on the surface of the central rod 106. The steering handle 105 can rotate relative to the central rod 106 and can drive the central rod 106 to rotate synchronously. A limit block is fixedly installed on the surface of the extension frame 3. A limit groove is opened on the surface of the steering handle 105. When the steering handle 105 rotates to the position where the limit groove corresponds to the limit block, the steering handle 105 is pushed to move along the axial direction of the central rod 106 and the limit groove is fitted on the outside of the limit block, thereby restricting the steering handle 105 and the central rod 106 from continuing to rotate, so that the central rod 106 can be positioned after the adjustment is completed. A limiting ring 201 is fixedly installed inside the guide roller 101. The limiting ring 201 is sleeved on the outside of the center rod 106 and is used to limit the position of the center rod 106 inside the guide roller 101 so that the center rod 106 can maintain the installation position corresponding to the spiral sleeve 107.

[0019] Example 2: Please refer to Figures 5-8 A height-adjustable guide device for cable winding reel, based on Embodiment 1, wherein a guide tube 203 is sleeved inside the spiral sleeve 107, a transmission cylinder 202 is fixedly installed at one end of the limiting ring 201 near the guide tube 203, the guide tube 203 is fixedly connected to the transmission cylinder 202 so that the guide tube 203 can remain relatively fixed with the transmission cylinder 202, a spiral tube 205 is slidably installed inside the guide tube 203, and one end of the center rod 106 away from the limiting ring 201 passes through the inside of the spiral tube 205 so that the center rod 106 can form a transmission engagement with the spiral tube 205; A guide block 206 is fixedly installed on the surface of the center rod 106. The guide block 206 passes through the spiral groove on the surface of the spiral tube 205. When the center rod 106 rotates, the guide block 206 can move along the spiral groove on the surface of the spiral tube 205. Through the cooperation between the spiral groove and the guide block 206, the spiral tube 205 moves axially relative to the guide tube 203, thereby converting the rotational motion of the center rod 106 into the axial movement of the spiral tube 205. A locking cylinder 204 is sleeved inside the transmission cylinder 202. After the spiral tube 205 moves a certain distance axially, it contacts the end of the locking cylinder 204 and pushes the locking cylinder 204 to move axially synchronously. The locking cylinder 204 is connected to the center rod 106 by a return spring 304, so that after the locking cylinder 204 is pushed by the spiral tube 205 and moves, it can return to its original position by the elastic action of the return spring 304. Multiple push blocks 302 are slidably installed inside the transmission cylinder 202 along the circumference, and multiple transmission blocks 305 are fixedly installed on the surface of the limiting ring 201 along the circumference. A locking block 301 is provided between each two adjacent transmission blocks 305, so that multiple locking blocks 301 can be located between adjacent transmission blocks 305 and move in the corresponding direction. The locking blocks 301 and each transmission block 305 are connected by spring pieces (not shown in the figure), so that after the locking blocks 301 move, they return to the initial state under the elastic force of the spring pieces. like Figures 7-9 As shown, the end of the push block 302 near the locking block 301 is set as an inclined surface, and the inclined surface abuts against the surface of the corresponding locking block 301. When the push block 302 moves toward the limiting ring 201, the inclined surface of the push block 302 can squeeze the locking block 301 and convert the axial movement of the push block 302 into the radial outward movement of the locking block 301, so that multiple locking blocks 301 can move synchronously in a direction away from each other. The spiral sleeve 107 has multiple locking grooves at one end near the limiting ring 201. Each locking groove is positioned in a corresponding position with a multiple locking block 301. After the multiple locking blocks 301 move away from each other, their ends can extend into the corresponding locking grooves. Thus, the cooperation between the locking blocks 301 and the locking grooves restricts the spiral sleeve 107 from continuing to rotate, thereby locking the spiral sleeve 107. Multiple guide blocks 306 are fixedly installed circumferentially on the surface of the locking cylinder 204. A guide groove 307 is opened on the side of the pushing block 302 near the locking cylinder 204. The guide blocks 306 are correspondingly inserted into the guide groove 307, so that when the locking cylinder 204 moves axially, the pushing block 302 can be driven to move synchronously through the cooperation of the guide blocks 306 and the guide groove 307. Multiple pushing blocks 302 are arranged circumferentially and are respectively connected to the transmission cylinder 202 through auxiliary springs 303, so that the pushing block 302 can move after being pushed by the locking cylinder 204, and reset by the elastic restoring force of the auxiliary spring 303 after the locking cylinder 204 releases the push. Among them, the elastic force of the return spring 304 is greater than that of the auxiliary spring 303, so that when the locking cylinder 204 is pushed by the spiral tube 205 and the pushing block 302 moves, and the spiral tube 205 releases the push on the locking cylinder 204, the return spring 304 can push the locking cylinder 204 to reset first, and the pushing block 302 returns to the initial position under the action of the auxiliary spring 303, thereby releasing the locking engagement between the locking block 301 and the spiral sleeve 107; It is worth noting that the surface of the steering handle 105 is provided with an annular scale. The annular scale is used to display the rotation angle of the center rod 106 and the movement position of the spiral tube 205. When it is necessary to adjust the winding height of different cables, the steering handle 105 is rotated, so that the center rod 106 drives the spiral tube 205 to move along the axial direction of the guide tube 203. The operator can adjust the steering handle 105 to the predetermined position according to the scale corresponding to the annular scale to obtain a guide position that is adapted to different cable specifications or different winding heights, thereby improving the accuracy of device adjustment and repeatability of positioning.

[0020] The working principle of this invention is: In use, firstly, adjust the initial position of the pressing rod 104 according to the predetermined winding height of the wire harness on different reels 2. Rotate the steering handle 105, which drives the center rod 106 to rotate synchronously. During the rotation of the center rod 106, the spiral tube 205 moves along the axial direction of the guide tube 203 through the cooperation between the guide block 206 and the spiral groove on the surface of the spiral tube 205, thereby adjusting the initial distance between the spiral tube 205 and the locking cylinder 204. After adjusting it to the predetermined scale according to the annular scale on the surface of the steering handle 105, push the steering handle 105 so that the limiting groove on the surface of the steering handle 105 is sleeved on the outside of the limiting block on the surface of the extension frame 3, thereby restricting the steering handle 105 and the center rod 106 from continuing to rotate, so that the adjusted pressing rod 104 is kept in the corresponding initial position. Then, pass the wire harness through the guide ring 102 and the guide hole at the end of the pressing rod 104 in sequence, and rotate the reel 2 to wind the wire harness. During the winding process of the wire reel 2, the auxiliary motor 103 drives the spiral sleeve 107 to rotate. The spiral sleeve 107 drives the pressing rod 104 to move back and forth along the axial direction of the guide roller 101 through the cooperation between the threaded groove on its surface and the protrusion on the surface of the pressing rod 104. This allows the pressing rod 104 to continuously guide the wire harness, thereby gradually arranging the wire harness along the axial direction of the wire reel 2 and neatly winding it around the surface of the wire reel 2. As the number of winding layers of the wire harness on the surface of the wire reel 2 gradually increases, the winding height of the wire harness gradually increases, and it acts on the pressing rod 104, causing the pressing rod 104 to deflect at an angle as the winding height of the wire harness changes. At the same time, it drives the guide roller 101 to rotate accordingly. When the guide roller 101 rotates, the limiting ring 201 inside it rotates synchronously with the guide roller 101, and drives the transmission cylinder 202 and the guide tube 203 to rotate synchronously through the limiting ring 201. Since the guide tube 203 is fixedly connected to the transmission cylinder 202, when the guide tube 203 rotates, it drives the spiral tube 205 inside it to rotate synchronously. The center rod 106 remains stationary under the cooperation of the steering handle 105 and the limiting block, so that the spiral tube 205 gradually moves axially during the rotation through the cooperation between the guide block 206 and its spiral groove, and gradually approaches the locking cylinder 204. Since the initial distance between the spiral tube 205 and the locking cylinder 204 has been set by the steering handle 105 before the winding begins, as the pressing rod 104 deflects continuously, when the spiral tube 205 moves to the predetermined position, its end contacts the locking cylinder 204 and continues to move, pushing the locking cylinder 204 to move axially. During the movement of the locking cylinder 204, the cooperation between the guide block 306 and the guide groove 307 on the surface of the push block 302 drives multiple push blocks 302 to move synchronously, so that the inclined surface of the push block 302 presses the corresponding locking block 301, and converts the axial movement of the push block 302 into the radial outward movement of the locking block 301, so that the ends of multiple locking blocks 301 gradually extend into the locking groove corresponding to the end of the spiral sleeve 107. At this time, the locking block 301 and the locking groove restrict the spiral sleeve 107 from continuing to rotate, thereby restricting the output end of the auxiliary motor 103 from rotation. When the auxiliary motor 103 attempts to drive the spiral sleeve 107 to rotate in either the forward or reverse direction but fails to make the spiral sleeve 107 continue to rotate, the auxiliary motor 103 stops working, thereby keeping the pressing rod 104 in the current guide position, preventing the pressing rod 104 from continuing to move and causing compression or disturbance to the already wound wire harness. At this time, the wire harness can complete the regular winding to a predetermined height under the continuous guiding action of the pressing rod 104. Then, the wire harness is cut and the wire reel 2 that has been loaded with cable is removed. Then, an empty wire reel 2 is installed, and the next round of cable loading operation can be carried out. After replacing the new coil 2, since the deflection of the pressing rod 104 is a passive deflection that occurs as the winding height of the wire harness increases, the pressing rod 104 can return to its initial guide position after the wire harness is removed from the pressing rod 104, and drive the guide roller 101 to reset synchronously. When the guide roller 101 resets, the limit ring 201, the transmission cylinder 202, and the guide tube 203 rotate in the opposite direction, causing the spiral tube 205 to move in the opposite direction under the action of the guide block 206 and gradually move away from the locking cylinder 204. When the spiral tube 205 releases its push on the locking cylinder 204, the locking cylinder 204 returns to its initial position under the elastic restoring force of the return spring 304, and drives the push block 302 to reset synchronously. The multiple locking blocks 301 then release their engagement with the locking groove at the end of the spiral sleeve 107, allowing the spiral sleeve 107 to return to a rotatable state. Thus, after replacing the new coil 2, there is no need to readjust the steering handle 105 again, and the guiding mechanism can automatically return to the working state required for the next round of cable loading.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The height-adjustable guide device for cable winding onto a cable reel according to claim 5, characterized in that: A guide block (206) is fixedly installed on the surface of the central rod (106). The guide block (206) passes through the spiral groove on the surface of the spiral tube (205). When the central rod (106) rotates, the guide block (206) can move along the spiral groove on the surface of the spiral tube (205). The spiral tube (205) moves axially relative to the guide tube (203) through the cooperation between the spiral groove and the guide block (206).

7. The height-adjustable guide device for cable winding onto a cable reel according to claim 5, characterized in that: The transmission cylinder (202) is fitted with a locking cylinder (204). After the spiral tube (205) moves a certain distance along the axial direction, it contacts the end of the locking cylinder (204) and pushes the locking cylinder (204) to move synchronously along the axial direction. The locking cylinder (204) is connected to the center rod (106) by a return spring (304). After the locking cylinder (204) is pushed by the spiral tube (205) and moves, it can be restored to its original position by the elastic action of the return spring (304). Multiple push blocks (302) are slidably installed in the transmission cylinder (202) along the circumferential direction. Multiple conduction blocks (305) are fixedly installed on the surface of the limiting ring (201) along the circumferential direction.
