Description
Technical Field
[0001] This invention relates to the field of cable processing equipment technology, specifically to a cable wrapping tape uninterrupted splicing device and method. Background Technology
[0002] Before cable transportation, it is usually necessary to continuously wrap wrapping tape around the outside of newly manufactured cables to protect them. However, existing wrapping processes generally have the following problems: Continuation requires machine stoppage: When a roll of wrapping tape is about to run out, the wrapping machine needs to be stopped to replenish the tape, which leads to a decrease in overall efficiency; The guide belt angle is not adjustable: the angle of the wrapping belt chuck is fixed. If the guide belt angle does not match the wrapping path, it is easy to cause the wrapping belt to roll or deviate during traction, affecting the wrapping quality. Summary of the Invention
[0003] The first technical problem to be solved by the present invention is to provide a cable wrapping tape uninterrupted splicing device, which uses a hot-melt method to splice the wrapping tape, thus solving the problem that the existing wrapping tape splicing requires machine shutdown.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A cable wrapping tape uninterrupted splicing device includes a positioning frame and a wrapping tape storage device fixedly installed inside the positioning frame. Its core invention lies in the fact that there are two wrapping tape storage devices, and the positions of the two wrapping tape storage devices are symmetrical about the positioning frame. It also includes a hot-melt splicing device that is fixedly installed on the right side of the positioning frame and located in the middle of the two wrapping tape storage devices; The hot melt splicing device includes an outer shell, two sets of upper guide pulleys mounted side-by-side and rotatably on the upper left side of the outer shell, two sets of lower guide pulleys mounted side-by-side and rotatably on the lower left side of the outer shell, two sets of middle guide pulleys mounted side-by-side and rotatably on the middle right side of the outer shell, an upper guide channel opened inside the outer shell and extending obliquely from the upper guide pulley to the middle guide pulley, a lower guide channel opened inside the outer shell and extending obliquely from the lower guide pulley to the middle guide pulley, a middle guide channel opened between the two sets of middle guide pulleys and communicating with both the upper and lower guide channels, a clearance groove opened at the connection between the upper guide channel and the middle guide channel and at the connection between the lower guide channel and the middle guide channel, two sets of cylinders fixed above and below the outer shell and arranged opposite to each other, and two hot melt blocks respectively installed on the piston rods of the two sets of cylinders and capable of extending into the clearance grooves with the piston rods.
[0005] By adopting the above scheme, the two wrapping tape storage devices are arranged symmetrically, one above the other. When one wrapping tape is about to run out, the other wrapping tape storage device will send feedback to the two sets of cylinders and push the two sets of heat melters to heat melt the upper and lower wrapping tapes (thermoplastic tapes). There is no need to stop the machine. The staff only needs to replenish the wrapping tape on time, which makes the overall work efficiency higher.
[0006] As a preferred embodiment of a cable wrapping tape uninterrupted splicing device and method, the hot-melt splicing device further includes an upper temporary guide port opened at the right end of the housing and located above the two sets of intermediate guide pulleys, and a lower temporary guide port opened at the right end of the housing and located below the two sets of intermediate guide pulleys; the upper and lower temporary guide ports are used to temporarily store the wrapping tape to avoid pulling during traction.
[0007] As a preferred embodiment of a cable wrapping tape uninterrupted splicing device and method, the hot-melt splicing device further includes an upper protective cover fixed inside the housing and covering the top of the two sets of intermediate guide pulleys, and a lower protective cover fixed inside the housing and covering the bottom of the two sets of intermediate guide pulleys; the upper and lower protective covers can prevent the wrapping tape from contacting the rotating intermediate guide pulleys, thereby avoiding damage to the wrapping tape caused by the intermediate guide pulleys.
[0008] In a preferred embodiment of a cable wrapping tape uninterrupted splicing device and method, the interval between the two sets of upper guide pulleys is greater than or equal to the height of the upper guide track; the interval between the two sets of lower guide pulleys is greater than or equal to the height of the lower guide track; and the interval between the two sets of intermediate guide pulleys is greater than or equal to the height of the intermediate guide track, thereby ensuring the normal transport of the wrapping tape.
[0009] The second technical problem to be solved by the present invention is to provide a cable wrapping tape uninterrupted splicing device, which ensures the matching of the lead tape angle through an angle-adjustable chuck, improves wrapping efficiency and quality, and solves the problem of low wrapping efficiency caused by the non-adjustable lead tape angle of existing wrapping tapes.
[0010] To achieve the above objectives, the present invention adopts the following technical solution: Based on the above scheme, the left ends of the two sets of wrapping tape storage devices are simultaneously rotated and installed on the central axis fixed inside the positioning frame, and the two sets of wrapping tape storage devices can swing back and forth with the central axis as the reference. The wrapping tape storage device includes a swing arm, a conveyor motor fixedly installed at the front of the left end of the swing arm, a chuck rotatably installed at the front of the right end of the swing arm, a conveyor belt that synchronously drives the conveyor motor and the chuck, and an infrared sensor fixedly installed at the left end of the swing arm and facing the chuck for monitoring; wherein, each infrared sensor is electrically connected to two sets of cylinders and two sets of hot melt blocks through a control module. Its core improvements include: a swing reference seat fixed inside the positioning frame, a screw rotatably mounted on the inner wall of the swing reference seat, a lever seat threaded onto the screw, a limiting groove between the lever seat and the lever seat, an arc-shaped slide groove on the left side of the swing reference seat and concentric with the central axis, a slide rod fixed to the right end of the swing arm and extending into the arc-shaped slide groove and the limiting groove, a swing motor fixed inside the swing reference seat and arranged in the same direction as the screw, and a second conveyor belt that synchronously drives the swing motor and the screw.
[0011] By adopting the above scheme, the screw is driven to rotate by the swing motor, which drives the actuating seat to move linearly along the screw. Under the action of the slide bar, the swing arm swings. The chuck is adjusted by swinging, and the angle of the guide belt can be flexibly adjusted to ensure that the wrapping belt matches the wrapping path, avoids tangling during traction, and improves the wrapping efficiency and quality.
[0012] As a preferred embodiment of a cable wrapping tape uninterrupted splicing device and method, the wrapping tape storage device further includes a guide rod fixed inside the swing reference seat and arranged parallel to the screw; wherein the actuating seat is simultaneously slidably mounted on the guide rod, further improving the stability of the actuating seat moving linearly along the screw and preventing the actuating seat from rotating synchronously with the screw.
[0013] In a preferred embodiment of a cable wrapping tape uninterrupted splicing device and method, when the slide rod is located in the middle of the arc-shaped groove, the swing arm swings forward or backward along the arc-shaped groove at an angle of 20-40°. By adjusting the angle, the wrapping tape is matched with the wrapping path to avoid coiling during traction.
[0014] The third technical problem to be solved by the present invention is to provide a method for uninterrupted splicing of cable wrapping tape. By further streamlining and standardizing the operation method of the uninterrupted splicing device of cable wrapping tape, the problem of non-standard operation that is prone to occur during the operation of the uninterrupted splicing device of cable wrapping tape is solved.
[0015] To achieve the above objectives, the present invention adopts the following technical solution: A method for uninterrupted splicing of cable wrapping tape is disclosed. This method is implemented using a cable wrapping tape uninterrupted splicing device, in which two rolls of wrapping tape are placed on upper and lower wrapping tape storage devices, resulting in two different conveying scenarios.
[0016] Scenario 1: First, the wrapping tape of the lower wrapping tape storage device is fed, and then the wrapping tape of the upper wrapping tape storage device is continued. The operation steps are as follows: S1. Manually guide the lower wrapping tape of the lower wrapping tape storage device between the two sets of lower guide pulleys, then pass through the lower guide channel, the clearance groove, and the middle guide channel in sequence, and finally extend from between the middle guide pulleys to the next wrapping unit. S2. Manually guide the upper wrapping tape of the upper wrapping tape storage device between the two sets of upper guide pulleys, then pass through the upper guide channel and the clearance groove in sequence, and finally extend it 10-20mm from the upper temporary guide opening; S3. Under the traction of the wrapping unit, the lower wrapping tape wraps and packages the cable. S4. When the wrapping tape is about to run out, the lower wrapping tape storage device will send a feedback signal to the two sets of cylinders and the two sets of hot melt blocks. The two sets of cylinders will simultaneously push the two sets of hot melt blocks to move relative to each other, so that the upper wrapping tape and the lower wrapping tape can be quickly hot melted in the clearance groove. Then the cylinders will simultaneously push the two sets of hot melt blocks to leave the clearance groove. S5. Under the traction of the wrapping unit, the upper wrapping tape continues to wrap and package the cable; S6. The staff will replenish the wrapping tape and continue to wrap and package the cable in this way. The order of S1 and S2 can be interchanged.
[0017] Scenario 2: First, the wrapping tape from the upper wrapping tape storage device is fed, and then the wrapping tape from the lower wrapping tape storage device is continued. The operation steps are as follows: S1. Manually guide the upper wrapping tape of the upper wrapping tape storage device between the two sets of upper guide pulleys, then pass through the upper guide channel, the clearance groove, and the middle guide channel in sequence, and finally extend from between the middle guide pulleys to the next wrapping unit. S2. Manually guide the lower wrapping tape of the lower wrapping tape storage device between the two sets of lower guide pulleys, then pass through the lower guide channel and the clearance groove in sequence, and finally extend it 10-20mm from the lower temporary guide opening; S3. Under the traction of the wrapping unit, the upper wrapping tape wraps and packages the cable. S4. When the upper wrapping tape is about to run out, the upper wrapping tape storage device will send a feedback signal to the two sets of cylinders and the two sets of hot melt blocks. The two sets of cylinders will simultaneously push the two sets of hot melt blocks to move relative to each other, so that the upper wrapping tape and the lower wrapping tape can be quickly hot melted in the clearance groove. Then the cylinders will simultaneously push the two sets of hot melt blocks to leave the clearance groove. S5. Under the traction of the wrapping unit, the lower wrapping tape continues to wrap and package the cable; S6. Staff will replenish the wrapping tape as needed, and continue to wrap and package the cable in this way. The order of S1 and S2 can be interchanged.
[0018] The beneficial effects of this invention are as follows: 1. Uninterrupted operation and improved efficiency: Two wrapping tape storage devices are symmetrically arranged. When one wrapping tape is about to run out, the other wrapping tape storage device will send feedback to two sets of cylinders and push two sets of heat melters to heat melt the upper and lower wrapping tapes (thermoplastic tapes). There is no need to stop the machine. The staff only needs to replenish the wrapping tape on time, which makes the overall work efficiency higher. 2. Adjustable angle to avoid winding: The screw is driven by the swing motor to rotate, which drives the actuating seat to move linearly along the screw. Under the action of the slide bar, the swing arm swings. The chuck can be adjusted by swinging, and the angle of the guide belt can be flexibly adjusted to ensure that the wrapping belt matches the wrapping path, avoids winding during traction, and improves wrapping efficiency and quality. 3. Stable structure and reliable splicing: The expansion and contraction of the hot melt block are precisely controlled by the cylinder, and the avoidance groove and the middle guide channel work together to ensure the accuracy of the melting area and the splicing strength meets the requirements of wrapping.

Detailed Implementation
[0022] 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.
[0023] like Figure 1 As shown, a cable wrapping tape uninterrupted splicing device includes a positioning frame 1 and a wrapping tape storage device 2 fixedly installed inside the positioning frame 1; there are two wrapping tape storage devices 2, and the positions of the two wrapping tape storage devices 2 are symmetrical about the positioning frame 1; it also includes a hot-melt splicing device 3 fixedly installed on the right side of the positioning frame 1 and located in the middle of the two wrapping tape storage devices 2, the hot-melt splicing device 3 can melt and splice the two wrapping tapes without stopping the machine.
[0024] like Figure 2 As shown, the left ends of the two sets of wrapping tape storage devices 2 are simultaneously rotated and mounted on the central shaft 4 fixed inside the positioning frame 1. The two sets of wrapping tape storage devices 2 can swing back and forth with the central shaft 4 as a reference to improve the application flexibility of the wrapping tape storage devices 2.
[0025] like Figures 3 to 6As shown, the wrapping tape storage device 2 includes a swing arm 21, a conveyor motor 22 fixedly installed at the front left end of the swing arm 21, a chuck 23 rotatably installed at the front right end of the swing arm 21, a conveyor belt 24 that synchronously drives the conveyor motor 22 and the chuck 23, and an infrared sensor 25 fixedly installed at the left end of the swing arm 21 and facing the chuck 23 for monitoring. Each infrared sensor 25 is electrically connected to two sets of cylinders 39 and two sets of hot melt blocks 310 via a control module. Once the infrared sensor 25 detects the wrapping tape...

The two sets of cylinders 39 simultaneously push the two sets of hot melt blocks 310 to move relative to each other, so that the upper wrapping tape 5 and the lower wrapping tape 6 can be quickly hot melted in the clearance groove 38. Then the cylinders 39 simultaneously push the two sets of hot melt blocks 310 out of the clearance groove 38. In order to prevent the wrapping tape from breaking under the traction of the wrapping unit, the conveyor motor 22 can be started to assist the rotation of the chuck 23 if necessary, so as to reduce the tensile strength of the wrapping tape.
[0026] Continue as Figures 3 to 6 As shown, the wrapping tape storage device 2 also includes a swing reference seat 26 fixed to the inner side of the positioning frame 1, a screw 27 rotatably installed on the inner wall of the swing reference seat 26, a lever seat 28 threadedly mounted on the screw 27, a limiting groove 29 formed between the lever seat 28 and the lever seat 28, an arc-shaped slide groove 210 formed on the left side of the swing reference seat 26 and concentric with the central axis 4, a slide rod 211 fixed to the right end of the swing arm 21 and extending into the arc-shaped slide groove 210 and the limiting groove 29, and a fixedly installed on the swing arm 21. The reference base 26 contains a swing motor 212 arranged in the same direction as the screw 27, and a conveyor belt 213 that synchronously drives the swing motor 212 and the screw 27. The swing motor 212 drives the screw 27 to rotate, which in turn drives the actuating seat 28 to move linearly along the screw 27. Under the action of the slide rod 211, the swing arm 21 swings. The swing adjusts the chuck 23, which can flexibly adjust the guide belt angle to ensure that the wrapping belt matches the wrapping path, avoids tangling during traction, and improves wrapping efficiency and quality.

[0028] like Figures 3 to 6 As shown, when the slide bar 211 is located in the middle of the arc-shaped slide groove 210, the swing arm 21 swings forward or backward along the arc-shaped slide groove 210 at an angle of 20-40°. The angle is adjusted to ensure that the wrapping tape matches the wrapping path and to avoid tangling during traction.

The system includes: a guideway 37; clearance grooves 38 located at the connection points of the upper guideway 35 and the middle guideway 37, and the lower guideway 36 and the middle guideway 37; two sets of cylinders 39 fixed above and below the outer casing 31 and arranged opposite to each other; and two hot melt blocks 310 installed on the piston rods of the two sets of cylinders 39 and able to extend into the clearance grooves 38 along with the piston rods. Two wrapping tape storage devices 2 are arranged symmetrically above and below. When one wrapping tape is about to run out, the wrapping tape storage device 2 will feed back to the two sets of cylinders 39 and push the two hot melt blocks to heat melt the upper and lower wrapping tapes (thermoplastic tapes). There is no need to stop the machine. The staff only needs to replenish the wrapping tape on time, which makes the overall work efficiency higher.

[0032] Continue as Figures 7 to 8 As shown, the interval between the two sets of upper guide pulleys 32 is greater than or equal to the height of the upper guide rail 35; the interval between the two sets of lower guide pulleys 33 is greater than or equal to the height of the lower guide rail 36; and the interval between the two sets of middle guide pulleys 34 is greater than or equal to the height of the middle guide rail 37, thereby ensuring the normal conveying of the wrapping tape.
