Description

Technical Field

[0001] This utility model belongs to the field of cable winding and unwinding technology, specifically an adjustable tension cable winding and unwinding device. Background Technology

[0002] Cable winding and unwinding devices are used to wind or unwind cables. They are widely used in power, communications, and industrial manufacturing fields. They primarily use a winding structure to achieve the orderly winding and unwinding of cables, preventing tangling and knots, and improving the convenience of cable use and management. Common cable winding and unwinding devices typically include a winding roller and a drive unit. The drive unit rotates the winding roller to complete the cable winding and unwinding operation.

[0003] However, existing cable winding and unwinding devices have significant shortcomings in practical applications: First, they lack effective tension adjustment components, making the cable prone to loosening due to unstable tension during winding and unwinding. This not only hinders neat winding but may also affect the structural integrity of the cable due to mutual friction and compression. Second, dust, lint, and other impurities easily adhere to the cable surface. If not cleaned during winding and unwinding, these impurities will enter the winding structure during the winding process. Long-term accumulation will not only contaminate the cable but may also interfere with the normal operation of the winding and unwinding device and even adversely affect the insulation performance of the cable. Therefore, an adjustable tension cable winding and unwinding device is proposed to address the above problems. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides an adjustable tension cable winding and unwinding device, which has the advantages of being able to stably adjust the cable tension to ensure neat winding and cable integrity, and being able to clean impurities on the cable surface to maintain cleanliness and stable operation of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable tension cable winding and unwinding device, comprising a base plate, two symmetrically arranged upright plates fixedly connected to the rear side of the top of the base plate, a winding roller disposed between the upright plates, one end of the winding roller connected to the corresponding upright plate via a bearing, and the other end fixedly connected to a drive transmission assembly via a rotating rod penetrating the corresponding upright plate, a positioning reciprocating wheel assembly disposed on the front side of the winding roller, the positioning reciprocating wheel assembly being connected to the drive transmission assembly, a first guide ring, a second guide ring, and a third guide ring disposed at intervals on the front side of the positioning reciprocating wheel assembly, the first guide ring, the second guide ring, and the third guide ring being disposed sequentially from back to front on the base plate, a tension adjusting assembly disposed between the first guide ring and the second guide ring, and a cleaning assembly disposed between the second guide ring and the third guide ring.

[0006] Preferably, the positioning reciprocating wheel assembly includes two fixed plates arranged symmetrically on the left and right, a first lead screw and a first guide rod arranged correspondingly between the two fixed plates, a displacement block movably connected between the first lead screw and the first guide rod, the first lead screw being threadedly connected to the displacement block, the first guide rod passing through the displacement block, and two positioning wheels arranged symmetrically on the left and right mounted on the top of the displacement block.

[0007] Preferably, the drive transmission assembly includes a first sprocket fixedly connected to the end of a first lead screw, a second sprocket connected to the first sprocket via a chain, a take-up roller fixedly connected to the second sprocket via a rotating rod, a first motor connected to the side of the second sprocket away from the take-up roller via a motor shaft, and a corresponding upright plate connected to the first motor via a bracket.

[0008] Preferably, the first guide ring, the second guide ring, and the third guide ring each include a ring body, on which a plurality of evenly distributed rollers are fitted, and a support seat is fixedly connected to the bottom of the ring body, the support seat being disposed on a base plate.

[0009] Preferably, the tension adjustment assembly includes a second lead screw and a second guide rod arranged vertically on the base plate. The bottom end of the second lead screw passes through the base plate and is connected to a second motor. A lifting block is movably connected between the second lead screw and the second guide rod. One side of the lifting block is connected to a support roller through a bearing.

[0010] Preferably, the top end of the second lead screw and the second guide rod are connected to a top plate, the second lead screw is threadedly connected to a lifting block, and the second guide rod passes through the lifting block.

[0011] Preferably, the cleaning and scraping assembly includes a through pipe, in which a plurality of equally spaced rubber scraper rings are disposed, and two symmetrically arranged support plates are fixedly connected to the bottom of the through pipe, the support plates being disposed on a base plate.

[0012] Preferably, support blocks are fixedly connected to the four corners of the bottom of the base plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The tension adjustment component of this utility model can effectively solve the tension problem during cable winding and unwinding. By driving the second screw to rotate through the second motor, the lifting block is driven to rise and fall smoothly along the second guide rod, thereby adjusting the height of the support roller and changing the tension of the cable. This allows the cable to maintain a suitable and stable tension during winding and unwinding, which not only avoids the cable from becoming loose and difficult to wind, but also reduces the friction and squeezing caused by unstable tension, protects the structural integrity of the cable, and improves the neatness of cable winding and the service life of the cable. 2. This utility model cleaning and scraping component can specifically solve the problem of cleaning impurities on the cable surface. When the cable passes through the conduit, multiple rubber scraper rings evenly spaced inside the conduit can scrape off dust, lint, and other impurities adhering to the cable surface. This design can promptly clean contaminants on the cable surface and prevent impurities from entering the winding structure during the winding process. This not only avoids contamination of the cable by impurities but also reduces interference from impurities on the normal operation of the winding and unwinding device, ensuring the cleanliness of the cable and the stable operation of the winding and unwinding device, and further optimizing the overall effect of cable winding and unwinding.

[0016] 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.

[0017] like Figures 1 to 5As shown, this utility model provides an adjustable tension cable winding and unwinding device, including a base plate 1. Two symmetrically arranged vertical plates 2 are fixedly connected to the rear side of the top of the base plate 1. The vertical plates 2 provide a stable mounting support structure for the winding roller 3, ensuring the stability of the winding roller 3 during rotation. The winding roller 3 is arranged between the vertical plates 2. The winding roller 3 is the core component for realizing cable winding and unwinding, which can orderly wind or release the cable. One end of the winding roller 3 is connected to the corresponding vertical plate 2 through a bearing, and the other end is fixedly connected to a drive transmission assembly 4 through a rotating rod passing through the corresponding vertical plate 2. The drive transmission assembly 4 transmits the power of the first motor 44 to the take-up roller 3 and the positioning reciprocating wheel assembly 5, synchronizing the winding and cable positioning actions and improving the coordination of winding and unwinding. The positioning reciprocating wheel assembly 5 is located on the front side of the take-up roller 3 and is connected to the drive transmission assembly 4. The positioning reciprocating wheel assembly 5 drives the displacement block 54 to reciprocate along the first guide rod 53 via the first lead screw 52. Together with the positioning wheel 55, it ensures that the cable is evenly distributed on the take-up roller 3, preventing cable stacking and tangling. The front side of the positioning reciprocating wheel assembly 5 is provided with spaced-apart first... A first guide ring 6, a second guide ring 7, and a third guide ring 8 are sequentially mounted on the base plate 1 from back to front. The first guide ring 6, the second guide ring 7, and the third guide ring 8 guide the cable through the ring body 61 and the roller sleeve 62. The roller sleeve 62 converts the sliding friction between the cable and the ring body 61 into rolling friction, reducing cable wear. The support base 63 ensures the ring body 61 is securely installed. A tension adjustment component 9 is provided between the first guide ring 6 and the second guide ring 7. The tension adjustment component 9 can be controlled by a second motor. 93 drives the second lead screw 91 to rotate, causing the lifting block 94 to rise and fall along the second guide rod 92, thereby adjusting the height of the support roller 95, thus changing the tension of the cable, so that the cable always maintains a suitable tension during the winding and unwinding process, avoiding loosening or excessive stretching. A cleaning component 10 is provided between the second guide ring 7 and the third guide ring 8. The cleaning component 10 uses multiple rubber scraper rings 102 in the tube 101 to scrape off dust, lint and other impurities adhering to the surface of the cable when it passes through, keeping the cable clean. The support plate 103 provides stable installation support for the tube 101.

[0018] Specifically, the positioning reciprocating wheel assembly 5 includes two symmetrically arranged fixing plates 51. The fixing plates 51 provide an installation base for the first lead screw 52 and the first guide rod 53, ensuring their stable position. The first lead screw 52 and the first guide rod 53 are arranged correspondingly between the two fixing plates 51. A displacement block 54 is movably connected between the first lead screw 52 and the first guide rod 53. The first lead screw 52 is threadedly connected to the displacement block 54, and the first guide rod 53 passes through the displacement block 54. When the first lead screw 52 rotates, it can drive the displacement block 54 to move precisely along the first guide rod 53, realizing the reciprocating motion control of the displacement block 54. Two symmetrically arranged positioning wheels 55 are installed on the top of the displacement block 54. The positioning wheels 55 play a limiting and guiding role for the cable, so that the cable can move smoothly with the displacement block 54 and ensure the uniformity of winding.

[0019] Furthermore, the drive transmission assembly 4 includes a first sprocket 41 fixedly connected to the end of the first lead screw 52. The first sprocket 41 is connected to a second sprocket 43 via a chain 42. The first sprocket 41, chain 42, and second sprocket 43 constitute a reliable transmission structure that can stably transmit power with a stable transmission ratio, ensuring that the rotational speed of the take-up roller 3 matches that of the first lead screw 52. The second sprocket 43 is fixedly connected to the take-up roller 3 via a rotating rod. The side of the second sprocket 43 away from the take-up roller 3 is connected to a first motor 44 via a motor shaft. The first motor 44 provides a power source for the entire take-up and unwinding device, driving the take-up roller 3 to rotate and positioning the reciprocating wheel assembly 5 to move. The first motor 44 is connected to the corresponding upright plate 2 via a bracket, which ensures that the first motor 44 is securely installed and will not shift during operation.

[0020] Furthermore, the first guide ring 6, the second guide ring 7, and the third guide ring 8 all include a ring body 61. Multiple evenly distributed rollers 62 are fitted on the ring body 61. The rollers 62 can rotate freely, reducing the frictional resistance when the cable passes through and preventing the cable from being scratched. A support base 63 is fixedly connected to the bottom of the ring body 61. The support base 63 is located on the base plate 1 and can stably fix the ring body 61 on the base plate 1, ensuring the overall structural stability of the guide ring.

[0021] It is worth noting that the tension adjustment component 9 includes a second lead screw 91 and a second guide rod 92 vertically arranged on the base plate 1. The bottom end of the second lead screw 91 passes through the base plate 1 and is connected to a second motor 93. The second motor 93 provides power for tension adjustment and can precisely control the rotation of the second lead screw 91, thereby realizing the height adjustment of the lifting block 94. The lifting block 94 is movably connected between the second lead screw 91 and the second guide rod 92. One side of the lifting block 94 is connected to a support roller 95 through a bearing. The support roller 95 is connected through a bearing and can rotate with the movement of the cable, reducing friction damage to the cable. At the same time, the tension state of the cable is changed by the lifting of the lifting block 94.

[0022] It is worth noting that the top of the second lead screw 91 and the second guide rod 92 are connected to a top plate 96. The top plate 96 provides top limit and support for the second lead screw 91 and the second guide rod 92, preventing the lifting block 94 from leaving the guide rod range and ensuring the integrity of the structure. The second lead screw 91 is threaded to the lifting block 94, and the second guide rod 92 passes through the lifting block 94. The second guide rod 92 provides guidance for the lifting of the lifting block 94, ensuring that its movement is smooth and does not deflect, making the tension adjustment more precise.

[0023] It is worth mentioning that the cleaning and scraping assembly 10 includes a tube 101, inside which are arranged multiple equally spaced rubber scraper rings 102. The multiple equally spaced rubber scraper rings 102 can scrape the cable multiple times to more thoroughly remove surface impurities. Moreover, the rubber material is soft and will not damage the cable sheath. The bottom of the tube 101 is fixedly connected to two symmetrically arranged support plates 103. The support plates 103 are set on the base plate 1. The two symmetrical support plates 103 can evenly support the tube 101, keeping the tube 101 horizontal and stable, and ensuring that the cable can pass through smoothly and be scraped evenly.

[0024] It is worth emphasizing that support blocks are fixedly connected to the four corners of the bottom of the base plate 1. The support blocks are distributed at the four corners of the base plate 1, which can make the overall force of the device even, improve the stability of the device when it is placed, and avoid the device tilting due to uneven ground or other factors.

[0025] The first motor 44 and the second motor 93 are existing technologies and will not be described in detail. In addition, this utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0026] Working principle and process: The cable passes sequentially through the third guide ring 8, the cleaning assembly 10, the second guide ring 7, the tension adjustment assembly 9, the first guide ring 6, and the positioning reciprocating wheel assembly 5 before being wound onto the take-up roller. The first motor 44 of the drive transmission assembly 4 starts, driving the take-up roller 3 to rotate via the second sprocket 43 to achieve cable winding and unwinding. Simultaneously, the first sprocket 41 drives the first lead screw 52 of the positioning reciprocating wheel assembly 5 to rotate via the chain 42. The rotation of the first lead screw 52 causes the displacement block 54 to reciprocate along the first guide rod 53, thereby positioning the cable. The positioning wheel 55 at the top of the moving block 54 guides the cable to be evenly wound on the take-up roller 3. The second motor 93 of the tension adjustment component 9 drives the second lead screw 91 to rotate, which drives the lifting block 94 to rise and fall along the second guide rod 92. The cable tension is adjusted by the support roller 95 to maintain a suitable tension. The cable passes through the through tube 101 of the cleaning component 10. The rubber scraper ring 102 in the through tube 101 scrapes away impurities on the surface of the cable. Then it is guided by the second guide ring 7 and the third guide ring 8, and finally the orderly winding, tension adjustment and cleaning process of the cable is completed.
