Description

Technical Field

[0001] This utility model relates to the field of automated packaging equipment technology, specifically to an automatic heat shrinking equipment for heat shrink sleeves. Background Technology

[0002] Heat shrink tubing is a tubular material made of radiation-crosslinked polyolefin or adhesive-containing hot melt adhesive, possessing properties such as high-temperature shrinkage, flexibility, flame retardancy, insulation, and corrosion resistance. Its working principle involves heating to cause the material to shrink radially, tightly wrapping it around the surface of the object being protected, forming a wear-resistant, corrosion-resistant, and impact-resistant protective layer. With the increasing level of industrial automation, traditional manual heat shrinking methods (such as using a hot air blower to individually blow each tube) are inefficient, have unstable quality, are costly, and pose significant safety hazards, increasingly failing to meet the efficiency, precision, and consistency requirements of large-scale production. To solve these problems, we have developed an automated heat shrink tubing equipment to achieve a highly efficient and stable heat shrinking process. Utility Model Content

An adjusting plate 24 is slidably connected inside the material box 21. A screw 25 is threadedly connected to one side of the material box 21. One end of the screw 25 passes through the material box 21 and is rotatably connected to the adjusting plate 24. A guide rod 26 is fixedly connected inside the material box 21. The guide rod 26 passes through the adjusting plate 24 and is slidably connected to the adjusting plate 24. Two guide rods 26 are provided.

[0023] Adjusting the position of the adjusting plate 24 by screw 25 makes the width of the material box 21 match the length of the cut heat shrink sleeve, preventing the cut heat shrink sleeve from being too short and falling into the material box 21 in a messy manner, or changing its orientation and blocking the discharge hopper 23 when rolling on the inclined plate 22. The position of the guide rod 26 avoids the falling position of the cut heat shrink sleeve.

[0024] The feeding assembly 27 includes a fixed plate 271 and a feeding hole 272. The fixed plate 271 is fixedly connected to the material box 21, and the feeding hole 272 is opened through the material box 21. A motor 273 is installed at the bottom of the fixed plate 271. The output end of the motor 273 passes through the fixed plate 271 and is fixedly connected to a first conveying roller 274. A second conveying roller 275 is rotatably connected to the fixed plate 271. The first conveying roller 274 is rotatably connected to the fixed plate 271.

[0025] The cutting assembly 28 includes a vertical plate 281 and a cutting opening 282. The vertical plate 281 is fixedly connected to the top of the material box 21.

[0026] The material pushing assembly 29 includes a material pushing seat 291, which is fixedly connected to the material box 21 and the base 1 respectively. The material pushing seat 291 has a pushing groove 292, and a material pushing cylinder 293 is installed in the pushing groove 292. The movable end of the material pushing cylinder 293 passes through the material box 21 and is fixedly connected to an L-shaped push plate 294.

[0030] The heating element 34 is connected to an external power source. The heating element 34 is U-shaped. The heating element 34 in the heating chamber 33 heats and shrinks the heat shrink sleeve to tighten the wire, thus achieving the purpose of fully automatic heat shrinking. It is highly efficient and avoids the disadvantages of manual operation, which poses great safety hazards.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] The working principle of this utility model is as follows: When the power supply to the motor 273, cutting cylinder 283, pushing cylinder 293, and heating element 34 is turned, the screw 25 rotates, causing the adjusting plate 24 to slide to a suitable position within the material box 21. The motor 273 is then started, causing the first conveying roller 274 to rotate, which in turn drives the second conveying roller 275 to rotate, thus causing the heat shrink sleeve to pass through the feed hole 272 and enter the material box 21. The cutting cylinder 283 is then started, causing its movable end to extend, pushing the cutter holder 285 to drive the blade 286 to cut the heat shrink sleeve. The cut heat shrink sleeve falls into the feed box 21. The heat shrink sleeve enters the hopper 23 along the inclined plate 22. At this time, the L-shaped push plate 294 closes the lower port of the hopper 23. The push cylinder 293 is activated to push the L-shaped push plate 294 so that the receiving port 295 is aligned with the lower port of the hopper 23. The heat shrink sleeve enters the receiving port 295. The push cylinder 293 continues to push the L-shaped push plate 294 so that the receiving port 295 is aligned with the feeding port 296. The heat shrink sleeve passes through the feeding port 296 and the feeding pipe 31 and enters the inner side of the heating plate 34 in the heating chamber 33. The wire to be fitted with the heat shrink sleeve is inserted into the heating chamber 33 and passed into the heat shrink sleeve. The heating plate 34 is activated to heat and shrink it.
