Abstract
Description
Technical Field
[0001] The utility model relates to the field of wrapping machines, and particularly relates to a zero-tension wrapping machine. Background Art
[0002] In the process of cable production, the wrapping machine is an indispensable and important device, mainly used for rotating various wrapping tapes (such as mica tapes, cotton paper tapes, aluminum foils, polyester films, etc.) through a turntable and tightly wrapping them around the core wire to achieve the insulation or protection function of the cable. In the existing wrapping tape machine during use, since the wrapping tape reel and the tape winding device for installing the wrapping tape reel are arranged on the same rotating shaft and rotate synchronously, in order to ensure that the wrapping tape on the wrapping tape reel can be continuously pulled into the tape winding device when the wrapping tape reel and the tape winding device rotate, it is usually necessary to pass the wrapping tape through the inside of the rotating shaft to the tape winding device. The existing method of pulling the wrapping tape through the rotating shaft is to fix the end of the wrapping tape on an elastic metal strip and use the metal strip to pass through the rotating shaft to achieve the insertion of the wrapping tape. However, in this method, the fixation of the wrapping tape and the metal strip is relatively troublesome, and since the surface of the metal strip is relatively smooth, the wrapping tape is likely to fall off the metal strip during the pulling process, resulting in a more troublesome wrapping tape pulling step. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a zero-tension wrapping machine. The wrapping machine clamps and fixes the wrapping tape on the traction member and moves the traction member so that the wrapping tape passes through the through-hole to complete the operation of passing the wrapping tape through the rotating shaft, thereby reducing the difficulty of fixing between the wrapping tape and the traction member and reducing the probability of the wrapping tape falling off the traction member.
[0004] The technical solution adopted by the utility model to solve the above problems is as follows:
[0005] A zero-tension wrapping machine includes a frame, a wrapping tape reel, and a winding member. A rotating base is arranged inside the frame. The wrapping tape reel and the winding member are coaxially and fixedly connected to a rotating shaft. The rotating shaft is rotatably arranged inside the rotating base. The wrapping tape reel, the winding member, and the rotating shaft are driven to rotate by a driving device. A through-hole is penetratingly opened on the rotating shaft. The two ends of the through-hole are respectively opened inside the wrapping tape reel and the winding member. A traction member for clamping the wrapping tape is slidably inserted inside the through-hole.
[0006] In the above technical solution, preferably, the traction member includes a sleeve rod, an insertion rod, and a sliding member. The sleeve rod is in a hollow cylindrical shape. The insertion rod is slidably arranged inside the cavity of the sleeve rod. The sliding member is sleeved on the sleeve rod. The sliding member is close to the left end of the sleeve rod and the left end of the sliding member abuts against the sleeve rod. The insertion rod is fixedly connected to the sliding member through a strip-shaped hole on the sleeve rod.
[0007] In the above technical solution, preferably, an outer pulling ring is fixed to the right end of the sleeve rod, and an inner pulling ring is fixed to the right end of the insertion rod. The inner pulling ring is slidably arranged left and right inside the outer pulling ring.
[0008] In the above technical solution, preferably, a spring is sleeved on the sleeve rod, and both ends of the spring abut against the right end of the sleeve rod and the sliding member respectively.
[0009] In the above technical solution, preferably, a plurality of support rods are arranged on the outer side of the tape wrapping disc at equal intervals in a circular shape, and the through hole is located between the tape wrapping disc and the support rods.
[0010] In the above technical solution, preferably, the winding member includes a chassis and two winding rods that cooperate to form a horn shape, and two rollers are rotatably arranged on the winding rods.
[0011] In the above technical solution, preferably, a detection roller is arranged on the winding rod, and the detection roller is close to the right end opening of the through hole.
[0012] Compared with the prior art, the present invention has the following advantages and effects:
[0013] When the present invention is in use, after the tape roll is sleeved and fixed on the tape wrapping disc, the tape is pulled out from the tape roll, and the end of the tape is fixedly clamped on the left end of the traction member. Then, the traction member is driven to move to the right and move out from the through hole to realize passing the end of the tape through the through hole. Finally, the tape is wound around the winding member and fixed on the core wire to complete the installation step of the tape. Since in the present invention, the tape can be clamped and fixed through the left end of the traction member, and the tape can pass through the through hole by moving the traction member, the operation of passing the tape through the rotating shaft is completed, thereby reducing the difficulty of fixing the tape to the traction member and reducing the probability of the tape falling off the traction member, so that the operation of passing the tape through the rotating shaft for installation is relatively simple.

[0018] Among them, there are a frame 1, a rotating base 11, a rotating shaft 12, a through hole 13, a tape wrapping disc 2, a support rod 21, a winding member 3, a tape winding rod 31, a roller 32, a detection roller 33, a chassis 34, a driving device 4, a traction member 5, a sleeve rod 51, a plug rod 52, a sliding member 53, a strip-shaped hole 54, an outer pulling ring 55, an inner pulling ring 56, a spring 57, and a core wire 6. Specific embodiments
[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, and the present invention is not limited to the following embodiments.
[0020] See Figures 1 - 4 , a zero-tension tape wrapping machine in this embodiment includes a frame 1, a tape wrapping disc 2, and a winding member 3. A rotating base 11 is arranged inside the frame 1. The tape wrapping disc 2 and the winding member 3 are coaxially and fixedly connected to a rotating shaft 12. The rotating shaft 12 is rotatably arranged inside the rotating base 11. The tape wrapping disc 2, the winding member 3, and the rotating shaft 12 are driven to rotate by a driving device 4. A through hole 13 is penetratingly opened on the rotating shaft 12. The two ends of the through hole 13 are respectively located inside the tape wrapping disc 2 and the winding member 3. A traction member 5 for clamping the tape is slidably inserted into the through hole 13.
[0021] When the present invention is in use, the tape roll is sleeved and fixed on the tape wrapping disc 2. The core wire 6 is horizontally passed through the rotating shaft 12 from left to right along the cavity located at the center position of the rotating shaft 12, so that the core wire 6 is located inside the winding member 3. Then the traction member 5 is inserted into the through hole 13 on the rotating shaft 12, so that the left end of the traction member 5 extends to the position of the tape wrapping disc 2. After that, the tape is pulled out from the tape roll and the end of the tape is fixedly clamped on the left end of the traction member 5. Then the traction member 5 is driven to move to the right and move out of the through hole 13 to realize passing the end of the tape through the through hole 13. Finally, the tape is wound around the winding member 3 and fixed on the core wire 6 to complete the installation step of the tape. Since in the present invention, the tape can be clamped and fixed through the left end of the traction member 5 and the tape is passed through the through hole 13 by moving the traction member 5, the difficulty of fixing the tape to the traction member 5 and the probability of the tape falling off the traction member 5 are reduced, so that the operation of passing the tape through the rotating shaft 12 for installation is relatively simple.
[0022] See Figure 1 , a plurality of support rods 21 arranged in a circular and equally spaced manner are provided on the outer side of the tape wrapping disc 2. The through hole 13 is located between the tape wrapping disc 2 and the support rods 21.
[0023] Before passing through the through hole 13, the strap is wound around a plurality of support rods 21 first. The support rods 21 can provide a certain tension to the strap, which can reduce the wrinkling situation that occurs when the strap turns up during movement in the through hole 13 and then winds around the core wire 6.
[0024] See Figure 1 , the described winding member 3 includes a chassis 34 and two winding rods 31 that cooperate to form a horn shape. Two rollers 32 are rotatably provided on the winding rods 31.
[0025] After passing through the through hole 13, the strap is wound around the rollers 32 on the winding rods 31 in sequence. The rotation of the rollers 32 reduces the frictional resistance when the strap moves. By driving the winding rod to rotate around the core wire 6 as the rotation axis 12, the strap can be continuously and evenly wound around the core wire 6, ensuring the uniformity after the core wire 6 is wound.
[0026] See Figure 1 , a detection roller 33 is provided on the winding rod 31, and the detection roller 33 is close to the right - end opening of the through hole 13.
[0027] The detection roller 33 is arranged between the through hole 13 and the rollers 32. By electrically connecting the detection roller 33 to a rotational speed detection device, the detection device can be implemented by installing a magnetic mark on the detection roller 33 and installing a Hall sensor on the winding rod 31 near the detection roller 33. The rotational speed of the detection roller 33 is converted into an electrical signal through the Hall sensor, so as to detect the rotational speed of the detection roller 33, which is a conventional rotational speed detection method in the art. When it is detected that the rotational speed of the detection roller 33 is zero, it indicates that the strap is exhausted or the strap has fallen off the winding rod 31, which is convenient for the staff to adjust in time and ensures the normal operation of the present utility model.
[0028] See Figures 2 - 4 , the described traction member 5 includes a sleeve rod 51, an insertion rod 52 and a sliding member 53. The sleeve rod 51 is in a hollow cylindrical shape. The insertion rod 52 is slidably arranged in the cavity of the sleeve rod 51. The sliding member 53 is sleeved on the sleeve rod 51. The sliding member 53 is close to the left end of the sleeve rod 51 and the left end of the sliding member 53 abuts against the sleeve rod 51. The insertion rod 52 is fixedly connected to the sliding member 53 through a strip - shaped hole 54 on the sleeve rod 51.
[0029] When fixing the strap to the traction member 5, first drive the insertion rod 52 and the sliding member 53 to move to the right, then wind the strap around the sleeve rod 51 on the left side of the sliding member 53, and then drive the sliding member 53 to move to the left so that the strap is clamped between the sleeve rod 51 and the sliding member 53 to realize the connection between the strap and the traction member 5; when removing the strap from the traction member 5, drive the sliding member 53 to move to the right to loosen the strap, so that the strap can be removed. The fixing and disassembling operations between the traction member 5 and the strap are simple, which can reduce the difficulty of the strap passing through the rotating shaft 12 and improve the efficiency of the strap passing through the rotating shaft 12.
[0030] See Figure 2 、 Figure 3 A pull ring 55 is fixed to the right end of the sleeve rod 51, and a pull ring 56 is fixed to the right end of the insertion rod 52. The pull ring 56 is slidably arranged left and right within the pull ring 55.
[0031] By driving the pull ring 56 to move within the pull ring 55 to drive the insertion rod 52 to move within the sleeve rod 51, the convenience of driving the insertion rod 52 to move is improved. When in use, hold the pull ring 55 in the palm and insert the finger into the pull ring 56, so that the movement of the pull ring 56 and the insertion rod 52 can be driven with one hand, making the use operation of the present utility model more convenient.
[0032] See Figure 2 、 Figure 3 A spring 57 is sleeved on the sleeve rod 51, and both ends of the spring 57 respectively abut against the right ends of the sleeve rod 51 and the sliding member 53.
[0033] After driving the insertion rod 52 and the sliding member 53 to move to the right by the pull ring 56, the spring 57 is compressed. At this time, wind the strap around the sleeve rod 51, and then release the force applied to the pull ring 56. Under the action of the spring 57, the sliding member 53 can automatically move to the left to clamp and fix the strap, improving the convenience of clamping the strap to the traction member 5. At the same time, under the action of the spring 57, it is ensured that the left end of the sliding member 53 always abuts against the sleeve rod 51, which can reduce the occurrence of the situation that the left end of the sliding member 53 separates from the sleeve rod 51 when pulling the traction member 5 to move to the right, resulting in the strap falling off, and ensures the stability of the function of the present utility model during use.
