Description

Technical Field

[0001] This invention relates to the technical field of cable sheathing, and more particularly to an automatic cable sheathing device and method. Background Technology

[0002] Cross-linked polyethylene insulated power cables refer to wires and cables made of cross-linked polyethylene insulation material. They have good high temperature resistance and insulation performance. After the initial processing is completed, they are usually wrapped with insulating tape using a wrapping device to further improve the insulation and corrosion resistance of the cable. Existing coating equipment uses various methods to achieve cable coating, such as a cable coating processing device with publication number CN221466343U, which includes a base, an extruder and a water tank. A wire feeding roller is installed on the top left side of the base, a first guide ring is installed on the right side of the wire feeding roller, an installation seat is installed on the right side of the first guide ring, and an extruder is installed in the top middle of the installation seat. Through holes are opened in the middle of the left and right sides of the extruder, and feeding pipes are installed on the top and rear sides of the extruder. When existing cable wrapping equipment is used to wrap cables, the wrapping position between the cable and the wrapping tape cannot be adjusted, making it impossible to adjust the wrapping density of the wrapping tape on the cable. When wrapping cables of different diameters, it is easy to have missed wrapping or over-wrapping. For example, in the aforementioned prior art, the connection point between the film output from the extruded agent and the cable cannot be adjusted, meaning that the film can only be wrapped at a fixed position on the cable, and the wrapping density cannot be adjusted. In addition, the device uses a direct wrapping method to wrap the film without applying adhesive to the surface of the cable before wrapping, which makes it impossible for the wrapping tape to adhere tightly to the cable, and it is easy to fall off after wrapping, which has certain limitations.

[0003] Therefore, there is an urgent need to design an automatic wire and cable wrapping device and method to solve the above problems. Summary of the Invention

[0014] An automatic cable wrapping method for use in the aforementioned automatic cable wrapping equipment includes the following steps: S1. When wrapping the cable, first put the cable winding wheel into the traction assembly and fix it with the positioning assembly; S2. After passing the cable to be wrapped through the coating unit and the wrapping unit in the wrapping box, fix it on the cable winding wheel, and then pull out the wrapping tape on the unwinding wheel so that it is initially wrapped around the surface of the cable with the cooperation of the winding assembly. S3. Start the traction component to drive the cable winding wheel to rotate and wind up the cable, and begin the cable wrapping operation. S4.

S6. Adjust the winding position of the wrapping tape and the cable by adjusting the component, thereby adjusting the winding density of the wrapping tape on the cable.

[0015] This invention provides an automatic wire and cable wrapping device and method. It has the following beneficial effects: 1. When this coating equipment is used to coat cables, the cable winding wheel can be firmly fixed on the positioning roller by the cooperation of the positioning component, and the cable winding wheel can be automatically rotated by the cooperation of the traction component. At the same time as the rotation, the cable can be automatically pulled and wound, thus realizing the automatic winding and pulling of the cable, and the automatic wrapping of the coating tape on the cable during the traction process, resulting in higher coating efficiency.

[0016] 2. When this coating equipment is used to coat cables, the liquid application component can be used to apply adhesive evenly to the surface of the cable while the cable is being pulled and moved. The adhesive is then quickly pre-cured by hot air blowing, which allows the coating tape to be evenly wrapped on the adhesive, effectively improving the stability and tightness of the coating.

[0017] 3. When this coating equipment is used to coat cables, the winding components work together to evenly wrap the coating tape on the pulley onto the cable during cable transport. This allows for quick completion of the coating process. After coating, the heating effect of the heat fusion ring and the blowing effect of hot air ensure that the coating tape adheres tightly to the outside of the cable, effectively improving the coating effect.

[0018] 4. When this coating equipment is used to coat cables, the winding position of the coating tape on the cable can be flexibly changed by adjusting the components, thereby adjusting the coating density of the coating tape. This allows it to adapt to the coating of cables of different thicknesses and sizes, achieving different coating densities and effectively avoiding situations of smearing or empty wrapping.

[0019] In summary, the present invention can uniformly apply adhesive to the outside of the cable before wrapping, so that the adhesive, wrapping tape and cable are tightly wrapped and adhered, effectively improving the wrapping effect of the wrapping tape. At the same time, the wrapping density of the wrapping tape can be flexibly adjusted according to the thickness of the cable, so as to achieve uniform wrapping of different cables and better wrapping uniformity.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Example 1: Refer to Figures 1-7 An automatic cable wrapping device includes a cable 6 to be wrapped, which is set on a support box 1. The device first applies an adhesive to the surface of the cable 6, and then wraps the cable 6 with a wrapping tape 40 evenly, thereby completing the automatic wrapping of the cable 6.

[0025] This coating equipment also includes: The positioning and traction unit is set on the support box 1 and includes a traction component and a positioning component. The traction component is equipped with a cable winding wheel 4 for pulling the winding cable 6. A fixing plate 3 is fixedly installed on the support box 1, and a positioning roller 13 is rotatably installed on the fixing plate 3. The cable winding wheel 4 is sleeved on the outside of the positioning roller 13. When wrapping the cable 6, first engage the cable winding wheel 4 into the positioning roller 13 to complete the initial fixation of the cable winding wheel 4.

[0026] The positioning assembly is used to achieve the compression positioning of the cable winding wheel 4. The positioning assembly includes a movable plate 8 that is slidably installed on the upper part of the support box 1. A threaded push rod 15 is threadedly installed on the movable plate 8, and an elastic pressure plate 16 is rotatably installed on the threaded push rod 15 through a limit spring. A telescopic compression ring 14 is fixedly installed on the elastic pressure plate 16, and the telescopic compression ring 14 is compressed against the side of the cable winding wheel 4. When the cable winding wheel 4 is engaged, first slide the movable plate 8 so that it slides on the support box 1 and separates from the positioning roller 13. Then, after the cable winding wheel 4 is engaged and fixed, pull the movable plate 8 back to its original position. At this time, rotate the threaded push rod 15 to drive the limit spring and the elastic pressure plate 16 to move as a whole. When the elastic pressure plate 16 moves, it will drive the telescopic extrusion ring 14 to move, so that the telescopic extrusion ring 14 moves to press and fit against the side of the cable winding wheel 4, thus completing the extrusion and positioning of the cable winding wheel 4 and preventing it from separating from the positioning roller 13.

[0027] When the positioning roller 13 rotates, it drives the cable winding wheel 4 to rotate. The rotation of the cable winding wheel 4 will drive the telescopic extrusion ring 14 and the elastic pressure plate 16 to rotate synchronously, without affecting the extrusion and positioning effect of the limit spring on the elastic pressure plate 16, the telescopic extrusion ring 14 and the cable winding wheel 4.

[0028] The traction assembly includes a servo motor 7 fixedly installed in the support box 1, and a drive roller 11 fixedly installed on the drive end of the servo motor 7. A transmission belt 12 is sleeved between the positioning roller 13 and the drive roller 11. Once the cable winding wheel 4 has finished pressing and positioning, the cable 6 to be wrapped can be pulled so that its end is wrapped around the cable winding wheel 4 and fixed thereto. At this time, the servo motor 7 is started to drive the drive roller 11 to rotate. The rotation of the drive roller 11 will drive the positioning roller 13 to rotate under the action of the transmission belt 12. The rotation of the positioning roller 13 will drive the cable winding wheel 4 on it to rotate. The cable winding wheel 4 will then gradually wind up the cable 6, so that the cable 6 is gradually wrapped around the cable winding wheel 4, completing the automatic winding of the cable 6.

[0029] The coating box 5 is set on the support box 1, and a coating unit and a coating unit are installed inside it; The coating unit can evenly apply adhesive, so that the wrapping tape 40 is tightly wrapped and adhered to the cable 6, which can effectively prevent the wrapping tape 40 from falling off. At the same time, it can recycle excess adhesive, effectively saving material costs and further ensuring the quality of the wrapping.

[0030] The wrapping unit can evenly wrap the wrapping tape 40 around the cable 6, and can flexibly adjust the wrapping density of the wrapping tape 40 according to the thickness and model of the cable 6. This can effectively avoid missing wrapping or empty wrapping, and can be combined with subsequent bonding and reinforcement treatment to make the wrapping tape 40 adhere more tightly to the cable 6, ensuring wrapping uniformity and stability, and improving the insulation and corrosion resistance of the cable 6.

[0031] The side of the support box 1 is equipped with a smart control panel 2. The smart control panel 2 is used to locate the opening and closing and operation status of the traction unit, the coating unit and the wrapping unit, so as to realize the automatic wrapping of the cable 6 and effectively improve the wrapping efficiency of the cable 6.

[0032] The support box 1 has two inspection doors on its side, through which the internal structure of the support box 1 can be inspected and replaced.

[0033] Example 2: Refer to Figures 1-4 as well as Figures 8-13 The difference between this embodiment and embodiment one is that the coating unit includes a liquid application component and a liquid collection component. The liquid application component is provided with two spray rings 35 for spraying adhesive onto the surface of the cable 6. The liquid collection component is used to recover excess adhesive and cure the adhesive on the surface of the cable 6.

[0034] The liquid loading assembly includes a processing tank 9 fixedly installed inside the support box 1, and a linkage rod 18 is rotatably installed between the support box 1 and the processing tank 9. A worm gear 17 is fixedly installed on the drive roller 11, and a worm wheel 19 that meshes with the worm gear 17 is fixedly installed on the linkage rod 18. While the servo motor 7 drives the drive roller 11 to rotate and pull the cable 6, the rotation of the drive roller 11 will drive the worm gear 17 on it to rotate. The rotation of the worm gear 17 will drive the worm wheel 19 that it is paired with to rotate. The rotation of the worm wheel 19 will drive the linkage rod 18 to rotate synchronously.

[0035] A coating component 23 is fixedly installed inside the coating box 5, and a spraying mechanism is installed between the coating component 23 and the treatment box 9. The spraying mechanism includes a partition plate 30 fixedly installed inside the treatment box 9, a reciprocating screw 33 fixedly installed on the linkage rod 18, a pressure plate 32 slidably installed inside the treatment box 9, and an adhesive is filled between the pressure plate 32 and the side of the treatment box 9. A ball nut disc 34 that cooperates with the reciprocating screw 33 is fixedly installed on the pressure plate 32. When the linkage rod 18 rotates, it drives the reciprocating screw 33 on it to rotate. The rotation of the reciprocating screw 33 drives the ball nut disc 34 that is fitted on it to move, so that the ball nut disc 34 moves back and forth on the reciprocating screw 33. When the ball nut disc 34 moves back and forth, it drives the pressure plate 32 to move back and forth. When the pressure plate 32 moves back and forth, it intermittently squeezes out the adhesive in the processing box 9.

[0036] The cooperation between the reciprocating screw 33 and the ball nut disk 34 is existing technology. The specific principle is as follows: the reciprocating screw 33 is a form of three-dimensional cam pair. Its specific structure consists of two threaded grooves with the same pitch and opposite directions of rotation. The two ends of the screw are connected by a transition curve. By rotating the screw, the side of the helical groove pushes the balls located in the helical groove of the ball nut disk 34 to make axial reciprocating motion. The reciprocating motion of the balls will drive the ball nut disk 34 to move back and forth. That is, when the reciprocating screw 33 rotates in one direction, it can drive the ball nut disk 34 to make it move linearly back and forth on the reciprocating screw 33.

[0037] In a further embodiment, both spray rings 35 are fixedly installed inside the coating component 23, and the cable 6 is located between the upper and lower spray rings 35. The processing box 9 is fixedly connected to an upper liquid pipe 27 for extruding adhesive, and the upper liquid pipe 27 and the two coating components 23 are both fixedly connected to a liquid guide pipe for conducting adhesive. When the pressure plate 32 squeezes the adhesive, it will be squeezed out through the upper liquid pipe 27 and then into the two spray rings 35 through the two liquid guide pipes. The adhesive will be sprayed out through the two spray rings 35. When the cable 6 is initially connected, it will pass through the coating component 23 in the sheath box 5 and move between the two spray rings 35. When the cable 6 is moved, it will come into full contact with the adhesive sprayed by the upper and lower spray rings 35. As the cable 6 moves, a layer of adhesive will be evenly applied to its surface.

[0038] The processing box 9 is equipped with a replenishment tube for replenishing adhesive, which can automatically replenish adhesive at any time. The processing box 9 is also equipped with a replacement tube, which can periodically remove adhesive from the processing box 9 for replacement.

[0039] In a further embodiment, the liquid collection assembly includes a liquid collection plate fixedly installed in the coating component 23, and the coating component 23 has a plurality of return holes 36 for recovering the adhesive. A return pipe 28 is fixedly connected between the liquid collection plate and the processing tank 9. Excess adhesive sprayed by the two spray rings 35 will fall to the bottom of the coating part 23 and fall onto the collection plate through the return hole 36. The excess adhesive can be transferred to the treatment tank 9 for recycling through the return pipe 28, thus completing the automatic recycling of excess adhesive and avoiding waste of adhesive.

[0040] The end of the coating component 23 is fixedly installed with a solidifying member 29. The end of the solidifying member 29 is provided with a scraping ring. After the cable 6 passes through the two spray rings 35, it will pass through the scraping ring and enter the solidifying member 29, and then pass out through the solidifying member 29. At this time, the scraping ring will scrape off the excess adhesive on the outside of the cable 6, so that the adhesive is evenly covered and coated on the surface of the cable 6, effectively improving the uniformity of adhesive coating and avoiding over-coating or missed coating.

[0041] A fan impeller 31 for generating negative pressure suction is fixedly installed on the linkage rod 18, and an air inlet filter plate is fixedly installed on the processing box 9. A heating air box 24 for heating and conducting air is provided on the processing box 9, and an upper air pipe 26 for conducting hot air is fixedly connected between the heating air box 24 and the condenser 29. When the linkage rod 18 rotates, it will drive the impeller 31 to rotate inside the processing box 9. When the impeller 31 rotates, it will draw external cold air into the processing box 9 through the air intake filter plate and inject it into the heating air box 24. At this time, the heating air box 24 will heat the cold air and turn it into hot air.

[0042] Hot air is directed through the upper air pipe 26 and injected into the solidifying unit 29, which blows hot air onto the cable 6 inside the solidifying unit 29, drying the adhesive on the surface of the cable 6 to a semi-solid state, preventing it from dripping during subsequent transportation, and improving its subsequent coating and bonding effect with the covering tape 40.

[0043] Example 3: Refer to Figures 1-4 as well as Figures 14-17 The difference between this embodiment and embodiment two is that the wrapping unit includes a winding component and an adjusting component. The winding component is provided with a tape release wheel for winding the wrapping tape 40. The wrapping tape 40 is wound onto the cable 6 by the winding component. The adjusting component is used to adjust the winding position between the wrapping tape 40 and the cable 6 to adjust the winding density.

[0044] The winding assembly includes a driven ring 37 rotatably mounted inside the covering box 5, a driven gear ring 38 fixedly mounted on the driven ring 37, and a drive gear 20 meshing with the driven gear ring 38 fixedly mounted on the linkage rod 18. When the linkage rod 18 rotates, it will drive the drive gear 20 on it to rotate. The rotation of the drive gear 20 will drive the driven gear ring 38 that meshes with it to rotate. When the driven gear ring 38 rotates, it will drive the driven ring 37 to rotate.

[0045] A wrapping frame 39 is fixedly installed on the driven ring 37, and a pulley is sleeved on the wrapping frame 39. A sliding frame is fixedly installed on the wrapping frame 39, and a sliding plate with a pulley hole is slidably installed on the sliding frame. The wrapping tape 40 on the pulley passes through the pulley hole and is wrapped and attached to the cable 6. Before wrapping, the pulley is first installed on the wrapping frame 39, and the wrapping tape 40 on it is pulled out so that it is initially wrapped around the cable 6. When the cable 6 is pulled and moved, the wrapping tape 40 will be pulled out from the wrapping frame 39 in sync, so that the wrapping tape 40 moves synchronously with the cable 6. The sliding plate can slide on the sliding frame and slide synchronously with the rotation of the covering belt 40 and the covering frame 39. It can also change the discharge position of the covering belt 40 synchronously with the change of the covering position of the covering belt 40, so as to realize the uninterrupted discharge and winding of the covering belt 40.

[0046] In a further embodiment, the adjustment assembly includes an adjustment cylinder 22 fixedly installed inside the enclosure box 5, an adjustment plate 44 slidably installed inside the adjustment cylinder 22, and an adjustment cylinder 21 cooperating with the cable 6 fixedly installed on the adjustment plate 44 via an adjustment rod 45. After passing through the solidifying member 29, the cable 6 passes through the driven ring 37 and enters the regulating cylinder 21, and is pulled out through the outside of the regulating cylinder 21.

[0047] Two positioning frames 41 are fixedly installed inside the adjusting cylinder 21, and the two positioning frames 41 are located at both ends of the hot melt ring 42. Two bonding rollers 46 for squeezing and binding the covering tape 40 are rotatably installed inside each of the two positioning frames 41. The corresponding bonding rollers 46 in the two positioning frames 41 are arranged vertically between each other. The vertically corresponding squeezing method is used to achieve full squeezing of the covering tape 40 and the cable 6, effectively increasing the squeezing range and improving the squeezing bonding effect. After the cable 6 enters the adjusting cylinder 21, the covering tape 40 can be pulled out to adhere to the surface of the cable 6 and pulled out synchronously with the cable 6. During the application and pulling out process, multiple bonding pressure rollers 46 in the two positioning frames 41 will squeeze the covering tape 40 and the cable 6, which can tightly press the covering tape 40 to adhere to the surface of the cable 6, so that the covering tape 40 can move with the traction of the cable 6, and at the same time, make the covering tape 40 and the cable 6 adhere more tightly, so as to prevent loosening later.

[0048] After the covering tape 40 is wrapped and bonded to the cable 6, when the cable 6 is pulled and moved, the driven ring 37 will rotate, causing the covering frame 39 and the covering tape 40 to rotate synchronously. While the covering tape 40 is rotating and releasing material, it will gradually wrap around the cable 6, thereby completing the wrapping of the covering tape 40 on the cable 6. In other words, while the cable 6 is being pulled and moved, the covering tape 40 is wrapped around the outer surface of the cable 6 one circle at a time, thereby completing the rapid wrapping of the covering tape 40. This ensures that the covering tape 40 is tightly bonded to the adhesive on the outside of the cable 6, effectively improving the uniformity and stability of the wrapping.

[0049] In a further embodiment, an air guide pipe 25 for conducting hot air is fixedly connected between the adjusting cylinder 22 and the heating air box 24; When wrapping different cables 6, the position of the adjusting cylinder 21 can be adjusted according to the thickness of the cable 6, and the wrapping density can be controlled by the distance between the adjusting cylinder 21 and the wrapping frame 39. When the distance between the adjusting cylinder 21 and the wrapping frame 39 is close, the contact point between the wrapping tape 40 and the cable 6 will move forward, and the wrapping density of the wrapping tape 40 on the cable 6 will increase. When the adjusting cylinder 21 is far away from the wrapping frame 39, the wrapping density will decrease. The wrapping density can be flexibly adjusted according to actual needs to achieve uniform wrapping of different cables 6 and avoid multiple wrapping (repeated wrapping) or missing wrapping (incomplete wrapping).

[0050] The hot air in the heating gas box 24 is injected into the adjusting cylinder 22 through the air guide pipe 25. When the air in the adjusting cylinder 22 increases, it will push the adjusting plate 44 forward. When the adjusting plate 44 moves, it will drive the adjusting rod 45 forward. In turn, the adjusting rod 45 will drive the adjusting cylinder 21 to move as a whole, which will increase the covering distance between the cable 6 on the adjusting cylinder 21 and the covering tape 40, thereby reducing the covering density of the covering tape 40. Two return spring rods are fixedly installed between the ends of the adjusting plate 44 and the adjusting cylinder 22. The adjusting cylinder 22 is equipped with a pressure relief pipe. When the adjusting plate 44 is pushed forward, it will squeeze the return spring rod at the front. When it is necessary to reduce the density, the pressure relief pipe can be opened to release the air in the adjusting cylinder 22. At this time, the return spring rod will automatically retract and reset, thereby pulling the adjusting plate 44 back. The return of the adjusting plate 44 will drive the adjusting cylinder 21 back through the adjusting rod 45, thereby reducing the wrapping distance between the cable 6 on the adjusting cylinder 21 and the wrapping tape 40, and thus increasing the wrapping density of the wrapping tape 40.

[0051] A heat fusion ring 42 is fixedly installed inside the regulating cylinder 21, and an elastic air supply pipe 43 is fixedly connected between the heat fusion ring 42 and the air supply pipe 25. Another part of the hot air in the air supply pipe 25 will be transported to the heat fusion ring 42 through the elastic air supply pipe 43 and blown out through the heat fusion ring 42. When the cable 6 is wrapped by the covering tape 40 and continues to be transported, it will pass through the heat fusion ring 42. At this time, the hot air blown out by the heat fusion ring 42 will be blown onto the covering tape 40, making it soften. After being squeezed by the bonding pressure roller 46 on the next positioning frame 41, the covering tape 40 will be more tightly attached to the surface of the cable 6, completing the second compression wrapping and further improving the wrapping density between the covering tape 40 and the cable 6.

[0052] The support box 1 is equipped with a limit frame 10, and two limit rollers are rotatably installed on the limit frame 10. After the cable 6 is wrapped, it will pass through the two limit rollers and then be wound onto the cable winding wheel 4. The two limit rollers are used to limit the cable 6 so that it can be horizontally pulled before entering the cable winding wheel 4, and can be smoothly wound onto the cable winding wheel 4 after passing through the limit rollers, thus completing a stable wrapping and winding.

[0053] The specific coating principle of this coating equipment is as follows: First, the cable winding wheel 4 is mounted on the positioning roller 13 and fixed by the positioning assembly. Then, the end of the cable 6 is passed through the coating component 23 inside the coating box 5, and then through the two spray rings 35 inside the coating component 23 before being inserted into the solidifying member 29. After being pulled out through the end of the solidifying member 29, it enters the driven ring 37, and after passing through the driven ring 37, it is inserted into the adjusting cylinder 21. At this time, the wrapping tape 40 can be pulled out and attached to the side of the cable 6, so that the cable 6 and the wrapping tape are properly aligned. After being squeezed by the pressure roller 46, the tape 40 is pulled out from the end of the adjusting cylinder 21. Then, the cable 6 and the wrapping tape 40 wrapped on it pass through the two limiting rollers on the limiting frame 10 and are wrapped and fixed on the cable winding wheel 4. This completes the initial wrapping operation of the cable 6 and the wrapping tape 40. At this time, the servo motor 7 can be started to drive the cable winding wheel 4 to rotate. The rotation of the cable winding wheel 4 will wind up the cable 6. When the cable 6 is wound up, it will move inside the wrapping box 5.

[0054] When the cable 6 moves inside the sheathing box 5, the coating unit and the sheathing unit can be activated to apply adhesive to the surface of the cable 6, and at the same time, the sheathing tape 40 can be automatically wrapped.

[0055] This invention also provides an automatic cable wrapping method for the aforementioned automatic cable wrapping equipment, comprising the following steps: S1. When wrapping the cable 6, first put the cable winding wheel 4 into the traction assembly and fix it by the positioning assembly; S2. After passing the cable 6 to be wrapped through the coating unit and the wrapping unit in the wrapping box 5, it is fixedly connected to the cable winding wheel 4. Then, the wrapping tape 40 on the unwinding wheel is pulled out so that it is initially wrapped around the surface of the cable 6 with the cooperation of the winding assembly. S3. Start the traction component to drive the cable winding wheel 4 to rotate and wind up the cable 6, and begin the wrapping operation of the cable 6. S4. When the cable 6 passes through the liquid loading assembly during the wrapping process, the spray ring 35 inside it will spray adhesive onto the surface of the cable 6, and after the adhesive is heated by the liquid collection assembly, the adhesive will be initially cured on the surface of the cable 6. S5. When the cable 6 passes through the winding assembly, the winding assembly will drive the unwinding pulley to rotate and wrap the covering tape 40 around the surface of the cable 6, thus completing the automatic wrapping of the covering tape 40. S6. Adjust the winding position of the covering tape 40 and the cable 6 by adjusting the component, thereby adjusting the winding density of the covering tape 40 on the cable 6.

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.
