It is widely used in industries such as food, beverage, and medicine, and is suitable for the collective packaging of multiple items, improving production efficiency and packaging quality.

[0003] The existing patent CN213974738U discloses a heat shrinkage machine. By arranging heating pipes on the inner wall of the furnace cavity, a heat preservation interlayer in the box wall, and cooperating with heat preservation curtain cloth arranged at the outlet position and the inlet position of the furnace cavity, the temperature in the furnace cavity can be quickly increased, preventing excessive heat from overflowing into the external environment.

[0004] However, due to the too small gap of the heat preservation curtain cloth in the above equipment, it is easy to cause small products to get stuck, resulting in a blockage phenomenon. In severe cases, it may even reduce the production efficiency. In addition, the blockage makes the product stay in a high-temperature environment for a long time, increasing the risk of product damage due to heat shrinkage. Therefore, this application provides a heat shrinker with an automatic adjustment function. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art and provide a heat shrinker with an automatic adjustment function.

A conveying pipe is arranged on the top of the heat receiving plate. The other end of the conveying pipe is provided with a heat dissipation box.

[0009] The technical effect of adopting the above technical solution is that the heat collecting plate in the heat collecting box can collect the heat at the top of the heating box, and then the heat is transported to the heat dissipation box through the conveying pipe.

[0010] As a preferred embodiment, a heat dissipation box slot is provided at the top of the heat dissipation box, a motor is provided at the top of the heat dissipation box away from the heat dissipation box slot, and a heat dissipation fan is provided at the bottom of the motor.

[0011] The technical effect of adopting the above technical solution is that by driving the heat dissipation fan at the bottom to rotate through the motor, the heat in the heat collecting plate can be sent into the heat dissipation box more quickly, and then the heat is discharged through the heat dissipation box slot at the top of the heat dissipation box by the rotation of the heat dissipation fan, so as to dissipate the heat of the equipment.

[0012] As a preferred embodiment, a collection component is provided on one side of the first fixing plate. The collection component includes telescopic legs, a support plate is provided at the top of the telescopic legs, a collection box is provided at the top of the support plate, and a second conveyor belt is provided in the collection box.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] As Figure 1 - Figure 2 shown, this embodiment provides a technical solution: a heat shrinker with an automatic adjustment function, including a first fixing plate 1. A heating box 5 is arranged on the top of the first fixing plate 1. Heating plates 10 are arranged on both sides inside the heating box 5. A first conveyor belt 4 is arranged on the top of the first fixing plate 1. Curtain components 3 are arranged on both sides of the heating box 5;

[0030] The curtain assembly 3 includes a support crossbar 31. A rotating shaft is provided inside the support crossbar 31. The support crossbar 31 is provided with a shielding piece 32 through the rotating shaft. A connecting hinge 33 is arranged between the shielding pieces 32. Weighted rollers 36 are arranged at both ends of the connecting hinge 33. Fixed plates two 34 are arranged on both sides of the support crossbar 31. Fixing plate slots 35 are formed in the fixed plates two 34. Through the connecting hinge 33, multiple shielding pieces 32 can be connected and fixed to each other. When a smaller product is processed and sent out through the first conveyor belt 4, since the weight of the single shielding piece 32 at the bottom is small, the smaller product will not be stuck by the shielding piece 32 during transportation. At the same time, the weighted rollers 36 on both sides enable the device to be clamped with the fixing plate slots 35 on the fixed plates two 34. Due to the arrangement of the weighted rollers 36, the shielding piece 32 is more relaxed when opened and will not have a jamming phenomenon, solving the technical problem that the product is stuck during transportation.

[0031] Furthermore, as Figure 4 shown: A collection assembly 9 is arranged on one side of the first fixing plate 1. The collection assembly 9 includes telescopic legs 91. A support plate 94 is arranged at the top of the telescopic legs 91. A collection box 92 is arranged at the top of the support plate 94. A second conveyor belt 93 is arranged inside the collection box 92. When the device finishes processing the product, the telescopic legs 91 can adjust the height of the collection assembly 9 to adapt to different terrains for convenient product collection. The product is conveyed to the collection box 92 through the second conveyor belt 93, realizing efficient collection. This design enables the collection assembly 9 to flexibly cope with various terrains, ensuring the smooth collection of products and improving production efficiency.

[0032] When the above device is in use, the temperature inside the heating box 5 is too high. As Figure 3 shown: In this solution, the heat dissipation assembly 6 includes a heat collection box 61. A heat collection plate 62 is arranged inside the heat collection box 61. A conveying pipe 63 is arranged at the top of the heat collection plate 62. The other end of the conveying pipe 63 is provided with a heat dissipation box 64. A heat dissipation box slot 65 is arranged at the top of the heat dissipation box 64. A motor 66 is arranged at the top of the heat dissipation box 64 away from the heat dissipation box slot 65. A heat dissipation fan 67 is arranged at the bottom of the motor 66. The heat collection plate 62 in the heat collection box 61 can effectively collect the heat at the top of the heating box 5. These heats are then transported to the heat dissipation box 64 through the conveying pipe 63. Inside the heat dissipation box 64, the motor 66 drives the heat dissipation fan 67 at the bottom to rotate, accelerating the transfer of heat from the heat collection plate 62 to the heat dissipation box 64. The continuous operation of the heat dissipation fan 67 helps to discharge the heat through the slot at the top of the heat dissipation box 64, ensuring the stable operation of the device and avoiding performance degradation or damage caused by overheating.

[0033] Working principle:

[0034] As Figure 1 - Figure 4 shown:

[0035] In use: The device can be supported by the support legs 2 to ensure the stability of the device. Place the product to be heat-shrunk on the conveyor belt 1 4. The heating plate 10 inside the heating box 5 shrinks the material. Through the connecting hinge 33, multiple shielding sheets 32 can be connected and fixed to each other. When the smaller product is processed and sent out through the conveyor belt 1 4, since the weight of the individual shielding sheet 32 at the bottom is small, the smaller product will not be stuck by the shielding sheet 32 during transportation. At the same time, the weighted rollers 36 on both sides enable the device to be clamped with the fixing plate slots 35 on the fixing plate 2 34. Due to the setting of the weighted rollers 36, the shielding sheet 32 is more relaxed when opening and will not cause jamming. The fixing plate 3 7 supported by the support block 8 can connect the curtain assembly 3. The heat collection plate 62 in the heat collection box 61 can effectively collect the heat at the top of the heating box 5. This heat is then transported to the heat dissipation box 64 through the delivery pipe 63. Inside the heat dissipation box 64, the motor 66 drives the heat dissipation fan 67 at the bottom to rotate, accelerating the transfer of heat from the heat collection plate 62 to the heat dissipation box 64. The continuous operation of the heat dissipation fan 67 helps to discharge the heat through the slots at the top of the heat dissipation box 64, ensuring the stable operation of the device and avoiding performance degradation or damage caused by overheating. When the device finishes processing the product, the telescopic leg 91 can adjust the height of the collection assembly 9 to adapt to different terrains for easy product collection. The product is transported to the collection box 92 through the conveyor belt 2 93 to achieve efficient collection. This design enables the collection assembly 9 to flexibly respond to various terrains, ensuring the smooth collection of products and improving production efficiency.
