Description
Technical Field
[0001] This utility model relates to the field of heat shrink tubing cutting technology, specifically to a heat shrink tubing cutting machine with a corrective guiding function. Background Technology
[0002] Heat shrink tubing is a specially designed heat shrink sleeve made of polyolefin material. The outer layer is made of high-quality, soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance and wear resistance, while the inner layer has the advantages of low melting point, waterproof sealing and high adhesion.
[0003] During the processing of heat shrink tubing, a cutting process is required. In this process, the heat shrink tubing is typically cut into several small segments using a cutting blade. After the heat shrink tubing strip is transported up, the cutting blade is placed at the required cutting length, and the process of cutting multiple segments of heat shrink tubing is achieved through automated drive.
[0004] In the existing heat shrink tubing cutting process, after cutting, the heat shrink tubing needs to be unloaded. During unloading, it needs to be conveyed and guided. Because the cut heat shrink tubing is shorter and lighter, its position may shift during the lifting of the cutter after cutting. It may not fall accurately into the unloading box during unloading. Falling outside the unloading box will result in waste and require extra cleaning by staff, reducing the overall efficiency of the process. Therefore, the existing heat shrink tubing cutting process has the problem of not being able to guide and limit the unloading of the cut heat shrink tubing. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.
[0032] refer to Figure 1 A cutting frame 1 is set up. Along the feeding direction, the cutting frame 1 is provided with a feeding end 2 for feeding the material strip, a cutting end 3 for cutting the long strip into segments, a guiding and flattening end 4 for guiding the cut material strip to transportation, and a feeding end 5 for straightening and unloading the cut product.
[0033] refer to Figure 2 The feeding end 2 includes a feeding rack 21, on which a conveyor belt 22 is driven. The feeding rack 21 can support the conveyor belt 22 for transportation. The heat shrink tubing material will be unwound along the surface of the conveyor belt 22 and form a long strip. It will be transported along the transmission direction of the conveyor belt 22 toward the cutting end 3 for cutting.
[0034] refer to Figure 3-4The cutting end 3 includes a cutting support frame 31, on which a cutting blade 32 is slidably mounted. The cutting blade 32 moves perpendicular to the transmission direction of the conveyor belt 22, cutting the strip vertically into several smaller segments. The cutting end 3 also includes a cutting slide rod 33, on which a cutting push plate 34, fixedly connected to the cutting blade 32, is slidably connected. A push plate 35 is fixedly connected to the top of the cutting slide rod 33, and several push cylinders 351 are fixedly connected to the push plate 35. The piston rod ends of the push cylinders 351 are fixedly connected to the cutting push plate 34, driving the cutting push plate 34 to move, thereby driving the cutting blade 32 to cut. Several pressing cylinders 341 are fixedly connected to the cutting push plate 34. The piston rod end of 41 passes through the surface of the cutting push plate 34 and is fixedly connected to the cutting pressure plate at the end. The cutting pressure plate can flatten the cutting part before cutting to reduce the cutting thickness. Several pressing slides 342 are fixedly connected between the cutting pressure plate and the cutting push plate 34. A return spring 343 is fixedly connected to the pressing slide 342. The bottom surface of the cutting pressure plate and the cutting blade 32 are flat. The cutting pressure plate can be lifted by the pressing cylinder 341 and returned to its original position by the return spring 343, pressing it on the surface of the material strip to be cut. A cutting placement plate 36 is provided on the bottom surface of the cutting pressure plate. The cutting placement plate 36 is fixedly connected to the cutting push plate 34. The material strip slides across the surface of the cutting placement plate 36, which provides support. During cutting, the cutting placement plate 36 can abut against the cutting blade 32 to cut the material strip.
[0035] refer to Figure 5-6The guide flattening end 4 includes a guide support frame 41, on which a guide slide rod 42 is fixedly connected. Several guide sliders 421 are slidably connected to the guide slide rod 42. A guide strip 422 is fixedly connected to one side of each guide slider 421. The guide strips 422 are symmetrically arranged and driven by a guide click located to the side. When a product flows between two guide strips 422, it will be driven to move along the transmission direction by the two guide strips 422. A drive plate 43 is slidably connected to the upper part of the guide slide rod 42. A fixed seat 44 is fixedly connected to the top of the drive plate 43. A connecting rod 441 is fixedly connected to the fixed seat 44. A guide cylinder 442 is fixedly installed on the connecting rod 441. The piston rod end of the guide cylinder 442 and the guide cylinder 442 are connected to the guide support frame 41. The connecting rod 441 is fixedly connected, and the drive plate 43 is fixedly connected to one side of the connecting piece 431, which is fixedly connected to the side wall of the guide slider 421. The extension and retraction of the output end of the guide cylinder 442 drives the upper guide slide 422 to move, thereby adjusting the distance between the two guide slides 422 to adapt to different specifications of products, and enabling the surfaces of the upper and lower guide slides 422 to be respectively attached to the top and bottom surfaces of the material strip. A guide connecting plate 423 is fixedly connected to one side of the guide slide 422, and a curved guide plate 424 is fixedly connected to the guide connecting plate 423. The two curved guide plates 424 have opposite curvature directions, and the two curved guide plates 424 form a yielding effect to each other, extending the guide distance and guiding the material strip to the unloading end 5.
[0036] refer to Figure 7-8 The feeding end 5 includes a feeding inlet 51 and several feeding rollers 52 arranged on one side of the feeding inlet 51. The feeding port is in front of the feeding rollers 52. After the small strip of material is cut and fed through the feeding port, the remaining long strip of material will be transported along the feeding rollers 52 for manual feeding. A limit plate 53 is slidably connected above the feeding rollers 52, and a limit post 54 is fixedly connected to the bottom of the limit plate 53. Several limit posts 54 are symmetrically arranged in pairs and inserted between two feeding rollers 52. The strip of material is corrected by adjusting the distance between the two limit posts 54 to ensure that the material does not deviate and fall out of the feeding end 5. A movable screw is provided in the middle of the limit plate 53. 531, a movable rotating head 532 is fixedly connected to one end of the movable screw 531, and a movable block 533 is slidably connected to the movable screw 531 and fixedly connected to the limiting plate 53. The moving direction of the movable block 533 is perpendicular to the length direction of the limiting plate 53. By rotating the movable rotating head 532, the movable block 533 will be driven to move along the length direction of the movable screw 531, and can push the two limiting plates 53 closer or further apart, thereby adjusting the distance between the limiting plates 53. The feeding end 5 also includes a feeding recycling box 55 set below several feeding rollers 52. The recycling box can recycle the small pieces of material that have been cut and entered the feeding end 5, thereby feeding.
[0037] The working principle of this machine is as follows: When using this heat shrink tubing cutting machine, the heat shrink tubing strip is unwound and transported along the conveyor belt 22 on the loading end 2. When it reaches the cutting end 3, the pressing cylinder 341 extends the cutting pressure plate, pressing it onto the surface of the strip. Then, under the clamping of the cutting pressure plate and the cutting placement plate 36, the cutting blade 32 cuts the strip under the drive of the pushing cylinder 351. After cutting, the strip cut into small segments is transported to the guide flattening end 4. The guide sliding strips 422 on the guide flattening end 4 move closer together under the drive of the guide cylinder 442 and press against the surface of the strip. Driven by the guide belt 422, the material is transported to the unloading end 5. Under the guidance of the curved guide plate 424, the material enters the unloading inlet 51 at the unloading end 5 and falls into the unloading recycling box 55. After collection, the remaining long strip of material will continue to be transported into the unloading inlet 51. The moving screw 531 is adjusted to adjust the width between the two limiting posts 54 to limit and clamp the material. The long strip of excess material will not fall into the unloading recycling box 55. Instead, it will be transported along the unloading roller 52 in the unloading end 5 to the side of the machine body for recycling by the staff, thus completing the cutting and unloading operation of the heat shrink tubing.
[0038] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
