Description

Technical Field

[0001] This utility model relates to the field of impregnation equipment technology, specifically to an impregnation treatment device for controlling cable rebound. Background Technology

[0002] Cables, especially high-modulus polyethylene cables and nylon cables, usually require impregnation during the production process. This impregnation with adhesives (such as polyurethane, epoxy resin, etc.) improves their abrasion resistance, aging resistance, and adhesion to other components.

[0003] Traditional impregnation equipment typically includes a pay-off frame, an impregnation tank, an extrusion roller, and a take-up frame. The workflow is as follows: the cable is drawn from the pay-off frame, impregnated in the impregnation tank, excess adhesive is squeezed out by the extrusion roller, and finally cured in the drying tunnel before being wound up by the take-up frame.

[0004] However, the aforementioned traditional equipment has a significant problem: the cable itself accumulates internal stress during the production process. After being soaked in the adhesive solution and heated (some adhesive solutions require heating) in the impregnation tank, this internal stress is released, causing the cable to rebound violently after leaving the extrusion roller and before entering the drying tunnel. This rebound manifests as irregular jumping and twisting of the cable, which not only causes the impregnated adhesive to be thrown off, polluting the equipment and the environment, and resulting in uneven impregnation, seriously affecting product quality; it may also cause the cable to detach from the guide wheel, causing production interruption and even leading to safety accidents.

[0005] Therefore, there is an urgent need to develop a specialized device that can effectively suppress the rebound of cables after impregnation, in order to ensure the stability, safety and consistency of the production process. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a cable rebound control impregnation treatment device with a reasonable structure that can effectively suppress cable rebound after impregnation and ensure uniform and stable impregnation quality.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A cable rebound control impregnation treatment device includes a cable delivery device, an impregnation tank, an extrusion device, and an anti-rebound device arranged sequentially along the cable travel direction. The extrusion device includes a frame, an extrusion box, a linear displacement mechanism, and an extrusion mechanism. The frame is connected to the impregnation tank, and the extrusion box is installed on the frame. Both ends of the extrusion box have through holes for accommodating cables. The linear displacement mechanism is located inside the extrusion box and above the through holes. The extrusion mechanism is drivenly connected to the linear displacement mechanism. The extrusion mechanism and the central axis of the two through holes are in the same vertical plane. The linear displacement mechanism controls the extrusion mechanism to move linearly. The anti-rebound device includes connecting plates fixed to the outer wall of the extrusion box and located at the upper and lower ends of the through holes, first cylinders installed on opposite sides of the two connecting plates, first U-shaped seats connected to opposite ends of the two first cylinders, and positioning cylinders fixedly connected in the first U-shaped seats. The two positioning cylinders are located between the two connecting plates and are arranged opposite each other.

[0009] Preferably, the wire feeding device includes two symmetrical wall panels, an I-beam wheel rotatably connected between the two wall panels, and a first driving mechanism for driving the I-beam wheel to rotate. The two wall panels are fixed to the end of the impregnation tank away from the extrusion device, and the two ends of the I-beam wheel are fixed with first shafts, and the two first shafts are rotatably connected to the two wall panels respectively.

[0010] The first drive mechanism includes a first motor, a drive wheel connected to the motor shaft of the first motor, a driven wheel fixedly connected to one of the first shafts, and a drive belt that drives the drive wheel and the driven wheel.

[0011] The above technical solution involves winding the cable around an I-beam reel, controlling the first motor to rotate the drive wheel, and then using the transmission belt and driven wheel to rotate the I-beam reel, thus releasing the cable.

[0012] Preferably, the impregnation tank contains a plurality of guide rollers that are staggered vertically along the cable conveying direction and are rotatably connected.

[0013] In the above technical solution, after the cable is released, it enters the impregnation tank and passes through all the guide rollers in sequence. Because the guide rollers are arranged in an alternating manner, the movement path of the cable is extended so that the adhesive can be fully impregnated on the cable.

[0014] Preferably, the linear displacement mechanism includes a lead screw rotatably connected to the extrusion box via a rotary bearing, guide rods fixed inside the extrusion box and located on both sides of the lead screw, a second motor installed outside the extrusion box and drivenly connected to the lead screw, and a slide block threadedly connected to the lead screw. The slide block has a sliding hole and is slidably connected to the guide rod through the sliding hole. The lead screw is located above the central axis of the two through holes.

[0015] The above technical solution controls the second motor to work, which drives the lead screw to rotate. During the rotation of the lead screw, the slide block will move along the guide rod.

[0016] Preferably, the extrusion mechanism comprises a second cylinder, an extrusion frame, a second U-shaped seat, a main pressure roller, a third U-shaped seat, a secondary pressure roller, a sleeve, a slide rod, a first spring, a second spring, and a second drive mechanism. The upper end of the second cylinder is fixed to the bottom surface of the slide rod by bolts, and the lower end of the second cylinder is fixed to the top of the extrusion frame. The extrusion frame is through-type. The second U-shaped seat and the third U-shaped seat are both located inside the extrusion frame. The two ends of the main pressure roller are fixed with second shafts. The main pressure roller is rotatably connected to the second U-shaped seat through the second shafts. The second drive mechanism includes a third motor installed on the outer wall of the second U-shaped seat, a main gear connected to the motor shaft of the third motor, and a driven gear fixed to one of the second shafts. The main gear meshes with the driven gear.

[0017] The sleeve is fixed to the bottom surface inside the extrusion frame. The slide rod is slidably connected inside the sleeve. The upper end of the slide rod is connected to the third U-shaped seat. The two ends of the auxiliary pressure roller are fixed with the third shaft. The auxiliary pressure roller is rotatably connected to the third U-shaped seat through the third shaft. The auxiliary pressure roller is arranged opposite to the main pressure roller. The two sides of the third U-shaped seat are connected with downwardly inclined diversion plates. The first spring is sleeved on the outside of the sleeve. The lower end of the first spring is connected to the bottom wall of the extrusion frame, and the upper end is connected to the third U-shaped seat. The second spring is located inside the sleeve. The lower end of the second spring is connected to the sleeve, and the upper end is connected to the slide rod.

[0018] In the above technical solution, after the cable enters the extrusion box through the through hole, the cable release device stops working. First, the cable is fixed by the anti-rebound devices at both ends of the extrusion box. Then, the second cylinder is extended, driving the second U-shaped seat to descend. The main pressure roller presses the cable onto the auxiliary pressure roller. Simultaneously, the linear displacement mechanism drives the extrusion mechanism to move within the extrusion box, thereby squeezing out excess glue from the cable. Furthermore, when the main pressure roller moves downward, it presses down on the auxiliary pressure roller, compressing the first and second springs. Simultaneously, the first and second springs provide upward support to the auxiliary pressure roller, preventing the extrusion device from being unable to move linearly within the extrusion box due to excessive contact between the main and auxiliary pressure rollers, and also preventing all the glue on the cable from being squeezed out due to excessive compression.

[0019] Preferably, the positioning cylinder, the main pressure roller, and the auxiliary pressure roller are all covered with a rubber layer or a polyurethane layer.

[0020] In the above technical solution, the surfaces of the positioning cylinder, main pressure roller, and auxiliary pressure roller are covered with a corrosion-resistant rubber layer or a polyurethane layer with a high coefficient of friction to increase the gripping force on the cable and prevent slippage.

[0021] Preferably, guide brackets are fixed at both ends of the frame, and guide wheels are rotatably connected to the guide brackets, with the guide wheels aligned with the through holes.

[0022] The above technical solution uses a guide wheel to guide the cable, allowing it to smoothly and horizontally enter and exit the extrusion box.

[0023] Preferably, the bottom of the extrusion box is connected to a liquid collection hopper, the liquid collection hopper is provided with a boss, a filter plate is placed on the boss, and a liquid collection basin is provided below the frame, the liquid collection basin is located below the discharge end of the liquid collection hopper.

[0024] In the above technical solution, the extruded adhesive is collected by a liquid collection hopper, filtered by a filter plate, and finally falls into a liquid collection basin, thus realizing the recycling of adhesive liquid.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The extrusion mechanism removes excess adhesive from the cable, preventing it from spilling and reducing environmental pollution. The adhesive is recyclable, further minimizing waste. The extrusion process also ensures the adhesive is applied more evenly across the cable.

[0027] During the extrusion process, an anti-rebound device completely solves the problem of rebound and jumping of the cable after impregnation due to stress release, ensuring a safe and stable production process. It avoids glue waste and uneven impregnation caused by rebound and glue splatter, guaranteeing a uniform glue layer on the cable surface and significantly improving the overall performance of the product.

Detailed Implementation

[0035] 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.

[0036] Example 1

[0037] Please see Figures 1-6 A cable rebound control impregnation treatment device includes a cable delivery device 1, an impregnation tank 2, an extrusion device 3, and an anti-rebound device 4 arranged sequentially along the cable travel direction. The cable delivery device 1 releases the cable, which enters the impregnation tank 2 and is coated with adhesive through immersion. After adhesive coating, the excess adhesive is removed by the extrusion device. During adhesive removal, the anti-rebound device 4 secures the cable to prevent rebound. Additionally, the impregnation treatment device described in this embodiment requires the use of a curing device and a take-up device, which are located on one side of the extrusion device 3. After adhesive removal, the cable enters the curing device for curing, and then the take-up device retrieves the cured cable. The curing device described in this embodiment can employ physical curing, primarily relying on solvent evaporation or melt cooling. Specifically, the solvent in the adhesive evaporates rapidly under heating, and the remaining polymer particles fuse together to form a continuous, dense solid film. The take-up device has the same structure as the cable delivery device 1 and is used to retrieve the cable. The problem this embodiment aims to solve is how to prevent cable rebound during the adhesive extrusion process after cable impregnation. The subsequent curing and winding processes are not the technical problems to be solved in this embodiment. Therefore, the specific structure and principle of the curing device and the winding device will not be described in detail in this embodiment.

[0038] like Figure 1 As shown, the cable release device 1 includes two symmetrical wall plates 101, a bobbin 102 rotatably connected between the two wall plates, and a first drive mechanism for driving the bobbin to rotate. The two wall plates 101 are fixed to the end of the impregnation tank 2 away from the extrusion device. First shafts are fixed to both ends of the bobbin 102, and the two first shafts are rotatably connected to the two wall plates 101 respectively. The first drive mechanism includes a first motor 103, a drive wheel 104 connected to the motor shaft of the first motor, a driven wheel 105 fixedly connected to one of the first shafts, and a transmission belt connecting the drive wheel and the driven wheel. The cable to be impregnated is pre-wound onto the bobbin 102. By controlling the first motor 103 to operate, the drive wheel 104 is driven to rotate. Through the cooperation of the transmission belt and the driven wheel 104, the bobbin 102 is driven to rotate, thus releasing the cable.

[0039] Multiple guide rollers 5, arranged in a staggered pattern along the cable conveying direction, are rotatably connected within the impregnation tank 2. The impregnation tank is filled with polyurethane or epoxy resin adhesive. After the cable is released, it enters the impregnation tank and passes through all the guide rollers in sequence. Due to the staggered arrangement of the guide rollers, the movement path of the cable is extended, allowing the adhesive to fully impregnate the cable. Additionally, a drain pipe is installed on the impregnation tank, equipped with a valve, which can be a ball valve. Contaminated adhesive in the impregnation tank can be discharged through the drain pipe.

[0040] The extrusion device 3 includes a frame 301, an extrusion box 302, a linear displacement mechanism, and an extrusion mechanism. The frame 301 is connected to the impregnation tank 2. The extrusion box 302 is installed on the frame 301. The two ends of the extrusion box 302 are provided with through holes 303 for accommodating cables. The linear displacement mechanism is located inside the extrusion box 302 and above the through holes 303. The extrusion mechanism is driven and connected to the linear displacement mechanism. The extrusion mechanism and the central axis of the two through holes 303 are in the same vertical plane. The linear displacement mechanism controls the extrusion mechanism to make linear movements.

[0041] like Figure 6 As shown, the linear displacement mechanism includes a lead screw 304 rotatably connected to the extrusion box 302 via a rotary bearing, guide rods 305 fixed inside the extrusion box and located on both sides of the lead screw, a second motor 306 installed outside the extrusion box and driven by the lead screw, and a slide block 307 threadedly connected to the lead screw. The slide block 307 has a sliding hole and is slidably connected to the guide rods 305 through the sliding hole. The lead screw 304 is located above the central axis of the two through holes 303. Controlling the second motor 306 to work drives the lead screw 304 to rotate, and during the rotation of the lead screw 304, it drives the slide block 307 to move along the guide rods 305.

[0042] like Figures 3-5As shown, the extrusion mechanism includes a second cylinder 308, an extrusion frame 309, a second U-shaped seat 310, a main pressure roller 311, a third U-shaped seat 312, a secondary pressure roller 313, a sleeve 314, a slide rod 315, a first spring 316, a second spring 317, and a second drive mechanism. The upper end of the second cylinder 308 is fixed to the bottom surface of the slide 307 by bolts, and the lower end of the second cylinder 308 is fixed to the top of the extrusion frame 309. The extrusion frame 309 is through-type. Both the U-shaped base 310 and the third U-shaped base 312 are located within the extrusion frame 309. The main pressure roller 311 has second shafts fixed to both ends, and the main pressure roller 311 is rotatably connected to the second U-shaped base 310 via the second shafts. The second drive mechanism includes a third motor 318 mounted on the outer wall of the second U-shaped base 310, a main gear 319 connected to the motor shaft of the third motor, and a driven gear 320 fixed to one of the second shafts. The main gear 319 meshes with the driven gear 320. Controlling the third motor 318 causes the main pressure roller to rotate through the engagement of the main gear and the driven gear, thereby extruding the cable.

[0043] The sleeve 314 is fixed to the bottom surface inside the extrusion frame 309. The slide rod 315 is slidably connected inside the sleeve 314. The upper end of the slide rod 315 is connected to the third U-shaped seat 312. The two ends of the auxiliary pressure roller 313 are fixed with the third shaft. The auxiliary pressure roller 313 is rotatably connected to the third U-shaped seat 312 through the third shaft. The auxiliary pressure roller 313 is arranged opposite to the main pressure roller 311. The two sides of the third U-shaped seat 312 are connected with downwardly inclined diversion plates 326. The first spring 316 is sleeved on the outside of the sleeve 314. The lower end of the first spring 316 is connected to the bottom wall of the extrusion frame 309, and the upper end is connected to the third U-shaped seat 312. The second spring 317 is located inside the sleeve 314. The lower end of the second spring 317 is connected to the sleeve 314, and the upper end is connected to the slide rod 315. When the main pressure roller 311 moves downward, it presses down on the auxiliary pressure roller 313, thereby squeezing the first spring 316 and the second spring 317. Simultaneously, under the action of the first and second springs, the auxiliary pressure roller 313 receives an upward supporting force. This prevents the extrusion device from having difficulty moving linearly within the extrusion box due to excessive contact between the main and auxiliary pressure rollers, and also prevents all the adhesive on the cable from being squeezed out due to excessive compression. Furthermore, the guide plate 326 guides the adhesive downward, allowing it to fall smoothly into the collection hopper. The guide plate also prevents the adhesive from falling onto the first spring, the second spring, the sleeve, and the slide rod, preventing the adhesive from drying and affecting the normal operation of these components.

[0044] like Figure 1 and Figure 6 As shown, guide brackets 321 are fixed at both ends of the frame 301, and guide wheels 322 are rotatably connected to the guide brackets 321. The guide wheels 322 are aligned with the through holes 303. The guide wheels can guide the cable so that it can smoothly and horizontally enter and exit the extrusion box 302.

[0045] To facilitate the maintenance of the extrusion mechanism inside the extrusion box 302, an openable cover is installed on the top of the extrusion box.

[0046] The anti-rebound device 4 includes a connecting plate 401 fixed to the outer wall of the extrusion box 302 and located at the upper and lower ends of the through hole 303, a first cylinder 402 installed on the opposite side of the two connecting plates, a first U-shaped seat 403 connected to the opposite ends of the two first cylinders, and a positioning cylinder 404 fixedly connected in the first U-shaped seat. The two positioning cylinders 404 are located between the two connecting plates 401 and are arranged opposite to each other.

[0047] The positioning cylinder 404, the main pressure roller 311, and the auxiliary pressure roller 313 are all covered with a corrosion-resistant, high-friction coefficient rubber layer or a polyurethane layer to increase the gripping force on the cable and prevent slippage.

[0048] The impregnation equipment described in this embodiment also requires a control cabinet and an air pump. The control cabinet contains a PLC controller, and the air pump provides power output to each cylinder through air supply pipelines. Control valves are installed on the air supply pipelines to open and close the corresponding air supply pipelines. The first motor, second motor, and third motor are preferably servo motors, and their control terminals are electrically connected to the controller to achieve speed synchronization.

[0049] The working principle of this embodiment is as follows:

[0050] The cable is released by the cable release device 1 and wound up by the cable take-up device, allowing the cable to first enter the impregnation tank 2 and pass through all the guide rollers 5 in sequence. After the adhesive is impregnated on the cable, it enters the extrusion box 302 through the through hole 303 at one end by the action of the guide wheel 322, and then exits through the through hole 303 at the other end. At this time, the cable release device 1 and the cable take-up device stop working. Then, the first cylinder 402 is controlled to extend, driving the two positioning cylinders 404 to move in opposite directions. The two positioning cylinders 404 clamp the cable, thereby keeping the cable in the extrusion box 302 stable and preventing rebound. Then, the second cylinder 308 is controlled to extend, driving the second U-shaped seat 310 to descend. The main pressure roller 311 presses the cable onto the auxiliary pressure roller 313. Then, the second motor 306 and the third motor 318 are started. The second motor 306 drives the slide 307 to move in the extrusion box. Through the action of the main pressure roller and the auxiliary pressure roller, the excess adhesive on the cable is squeezed out. During the extrusion process, the cable in impregnation tank 2 will remain for a period of time to improve the thoroughness and uniformity of the soaking. After the extrusion is completed, the anti-rebound device and the extrusion mechanism are released, and then the wire feeding device and the wire take-up device are started to allow the extruded cable to enter the curing device, while the next extrusion operation is started.

[0051] Example 2

[0052] Based on Example 1, the bottom of the extrusion box 302 is connected to a liquid collection hopper 323. A boss is provided inside the liquid collection hopper 323, and a filter plate 324 is placed on the boss. A liquid collection basin 325 is located below the frame 301, below the discharge end of the liquid collection hopper 323. A recovery pipe is provided on the liquid collection basin, with a valve installed on the pipe and a flange installed at the end. The extruded adhesive is collected by the liquid collection hopper 323, filtered by the filter plate 324, and finally falls into the liquid collection basin 325, achieving adhesive recycling. The filter plate 324 is placed on the boss for easy replacement. Replacement is simple: just open the cover and tilt the filter plate to insert it from the top of the extrusion box.
