[0002] In the tape manufacturing industry, automated production equipment is being used more and more widely to improve production efficiency and product quality. At the back end of the tape production line, the tape cutting device is one of the key pieces of equipment, responsible for cutting continuous tape into products of the required length and specifications.
[0003] Traditional tape cutting devices feed the tape to a designated position and then cut it. However, it is difficult to ensure that the position and size of each cut are completely consistent, which can easily lead to dimensional deviations and affect product quality. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a tape punching device for tape production, which solves the problem that traditional tape punching devices are unable to ensure cutting accuracy, easily leading to product size deviations and affecting product quality.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a tape punching device for tape production, comprising a support plate, a take-up roller rotatably mounted on one side of the support plate, the take-up roller being driven by a motor to rotate and take up the tape, and a magnetic cutting mechanism for cutting the tape and a cutting trigger mechanism for triggering the operation of the magnetic cutting mechanism are provided on one side of the support plate.
[0006] The cutting triggering mechanism includes a slot on one side of the support plate, located above the take-up roller, and a limiting cylinder connected inside the slot. A crossbeam is longitudinally slidably mounted on the outside of the limiting cylinder. A limiting roller corresponding to the take-up roller is rotatably mounted at the bottom of the crossbeam, and contacts the upper part of the take-up roller under the gravity of the limiting roller. A conductive post is provided on the upper part of the crossbeam. A limiting groove is provided on one side of the limiting cylinder, and a moving rod is longitudinally slidably inserted in the limiting groove. A conductive block corresponding to the conductive post is provided at the bottom of one end of the moving rod. As the tape is wound up, it pushes the limiting roller upward, causing the conductive post to contact the conductive block, triggering the operation of the magnetic cutting mechanism to complete the tape cutting operation.
[0007] Preferably, two guide rollers are rotatably arranged on both sides of one side of the support plate located on the magnetic cutting mechanism, and the tape passes between the two guide rollers when it is being wound up.
[0008] Preferably, the magnetic cutting mechanism includes a groove on one side of the support plate, an electromagnet is provided on the bottom side of the groove, a limiting shaft is connected between the electromagnet and the top side of the groove, an iron block is longitudinally slidably sleeved on the outside of the limiting shaft, a cutter is connected to one side of the iron block, and a spring is sleeved on the outside of the limiting shaft, with the two ends of the spring connected to the upper part of the iron block and the top side of the groove, respectively.
[0009] Preferably, after the conductive post comes into contact with the conductive block, a closed circuit is formed between the conductive post, the conductive block, and the electromagnet.
[0010] Preferably, the electromagnet's attraction to the iron block is greater than the spring's elastic force, so that when the electromagnet holds the iron block, the cutter cuts the tape.
[0011] Preferably, the cutting triggering mechanism further includes an adjustment part for adjusting the height of the conductive block, so that the tape is cut after being wound to different thicknesses. The adjustment part includes a screw rotatably disposed inside the slot and a knob rotatably disposed on the top of the support plate. The knob is used to adjust the rotation of the screw.

[0012] This utility model provides a tape punching device for tape production, which has the following advantages compared with the prior art:
[0013] The tape cutting device used in tape production triggers a cutting mechanism when the tape is wound up to the required thickness. This trigger mechanism then activates a magnetic cutting mechanism, which cuts the tape to ensure consistent cutting position and size each time. Furthermore, the thickness of the wound tape can be adjusted via an adjustment mechanism on the cutting trigger, allowing the tape to automatically trigger the cutting process when different thicknesses are reached.

[0019] 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.
[0020] Please see Figures 1-4 This utility model provides two technical solutions:
[0021] Example 1
[0022] Please see Figure 1 In this embodiment of the utility model, a tape cutting device for tape production includes a support plate 1. A take-up roller 2 is rotatably mounted on one side of the support plate 1. The take-up roller 2 is driven by a motor to rotate and take up the tape. A magnetic cutting mechanism 4 for cutting the tape and a cutting triggering mechanism 5 for triggering the operation of the magnetic cutting mechanism 4 are provided on one side of the support plate 1.
[0023] Please see Figures 2-3 In this embodiment of the present invention, the cutting triggering mechanism 5 includes a slot 51 disposed on one side of the support plate 1. The slot 51 is located above the take-up roller 2, and a limiting cylinder 52 is connected inside the slot 51. A crossbeam 53 is longitudinally slidably installed on the outside of the limiting cylinder 52. A limiting roller 54 corresponding to the take-up roller 2 is rotatably disposed at the bottom of the crossbeam 53. Under the gravity of the limiting roller 54, it contacts the upper part of the take-up roller 2. A conductive post 55 is disposed on the upper part of the crossbeam 53. A limiting groove 56 is disposed on one side of the limiting cylinder 52. A moving rod 57 is longitudinally slidably inserted in the limiting groove 56. A conductive block 58 corresponding to the conductive post 55 is disposed at the bottom of one end of the moving rod 57. As the tape is wound up, the limiting roller 54 moves upward, causing the conductive post 55 to contact the conductive block 58, triggering the operation of the magnetic cutting mechanism 4, and completing the tape cutting operation.
[0024] In the above scheme: the motor drives the take-up roller 2 to rotate and take up the tape. Under the gravity of the limit roller 54, when the tape is being taken up, the limit roller 54 will contact the top of the tape being taken up, which plays a guiding and limiting role in the taking up of the tape. As the tape is continuously taken up, the thickness of the tape gradually increases, thereby pushing the limit roller 54 upward, so that the crossbeam 53 slides upward on the limit cylinder 52. When the conductive post 55 contacts the conductive block 58 at the bottom of the moving rod 57, the magnetic cutting mechanism 4 will be triggered to complete the tape cutting operation.
[0025] Please see Figure 1 In this embodiment of the utility model, two guide rollers 3 are rotatably arranged on both sides of the support plate 1 located on both sides of the magnetic cutting mechanism 4. When the tape is wound up, it passes between the two guide rollers 3, and the guide rollers 3 play a guiding role in the winding of the tape.
[0026] Please see Figure 4 In this embodiment of the present invention, the magnetic cutting mechanism 4 includes a groove 41 disposed on one side of the support plate 1. An electromagnet 42 is disposed on the bottom side of the inside of the groove 41. A limiting shaft 43 is connected between the electromagnet 42 and the top side of the inside of the groove 41. An iron block 44 is longitudinally slidably sleeved on the outside of the limiting shaft 43. A cutter 46 is connected to one side of the iron block 44. A spring 45 is sleeved on the outside of the limiting shaft 43. The two ends of the spring 45 are respectively connected to the upper part of the iron block 44 and the top side of the inside of the groove 41.
[0027] In the above scheme: when the conductive post 55 contacts the conductive block 58 at the bottom of the moving rod 57, the power supply of the electromagnet 42 will be turned on. The electromagnet 42 will generate an attractive force on the iron block 44. Since the attractive force is greater than the elastic force of the spring 45, the electromagnet 42 will attract the iron block 44, so that the iron block 44 is attracted to the electromagnet 42. During the attraction, the iron block 44 will move down, thereby driving the cutter 46 to move down. When the cutter 46 moves down, it will cut the tape.
[0028] For further details, please refer to Figure 4 In this embodiment of the present invention, after the conductive post 55 comes into contact with the conductive block 58, a closed circuit is formed between the conductive post 55, the conductive block 58, and the electromagnet 42.
[0029] For further details, please refer to [link / reference]. Figure 4 In this embodiment of the invention, the attraction force of the electromagnet 42 to the iron block 44 is greater than the elastic force of the spring 45. When the electromagnet 42 attracts the iron block 44, the cutter 46 cuts the tape.
[0030] Example 2 differs from Example 1 in that:
[0031] Please see Figures 2-3In this embodiment of the present invention, the cutting triggering mechanism 5 further includes an adjustment part for adjusting the height of the conductive block 58, so that the tape is cut after being wound to different thicknesses. The adjustment part includes a screw 59 rotatably disposed inside the slot 51 and a knob 510 rotatably disposed on the top of the support plate 1. The knob 510 is used to adjust the rotation of the screw 59. A nut sleeve 511 is screwed onto the outside of the screw 59 by threads. The end of the moving rod 57 away from the conductive block 58 is connected to the nut sleeve 511.
[0032] In the above scheme: by rotating the knob 510, the screw 59 is driven to rotate, and the screw 59 drives the nut sleeve 511 to move, adjusting the conductive block 58 on the moving rod 57 to the required height. When the conductive post 55 contacts the conductive block 58, the height that the conductive post 55 moves up is the thickness of the tape being wound, so that the tape can be cut when wound to different thicknesses.
[0033] Working principle: The motor drives the take-up roller 2 to rotate and take up the tape. Under the gravity of the limit roller 54, when the tape is being taken up, the limit roller 54 will contact the top of the tape being taken up, which will guide and limit the tape taking up. As the tape is continuously taken up, the thickness of the tape gradually increases, which will push the limit roller 54 upward, so that the crossbeam 53 slides upward on the limit cylinder 52. When the conductive post 55 contacts the conductive block 58 at the bottom of the moving rod 57, the power supply of the electromagnet 42 will be turned on. The electromagnet 42 will generate a suction force on the iron block 44. Since the suction force is greater than the elastic force of the spring 45, the electromagnet 42 will attract the iron block 44, so that the iron block 44 is attracted to the electromagnet 42. During the attraction, the iron block 44 will move down, which will drive the cutter 46 to move down. When the cutter 46 moves down, it will cut the tape.
[0034] By rotating the knob 510, the screw 59 is driven to rotate, and the screw 59 drives the nut sleeve 511 to move, adjusting the conductive block 58 on the moving rod 57 to the required height. When the conductive post 55 contacts the conductive block 58, the height that the conductive post 55 moves up is the thickness of the tape being wound, thus enabling the tape to be cut when wound to different thicknesses.
[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
