Technical Field
[0001] The utility model relates to the technical field of processing equipment for rust-proof packaging bags, in particular to a heat shrinking machine. Background Art
[0002] Heat shrink machine, also known as shrink machine, heat shrink packaging machine, is one of the more advanced packaging methods on the market. It uses shrink film to wrap the product or package. After heating, the shrink film is wrapped tightly around the product or package, fully displaying the appearance of the item, improving the product's marketability and increasing its beauty and value.
[0003] A search revealed a Chinese patent publication number of CN209097147U, which discloses a portable heat shrink machine comprising a base, support columns fixedly connected to the left and right sides of the base bottom, a slide groove formed near the center of each support column on opposite sides of the base bottom, a chassis fixedly connected to the center of the base bottom, a cylinder fixedly mounted within the chassis, and a piston rod fixedly connected to the cylinder through its bottom output end. The portable heat shrink machine utilizes the cylinder, piston rod, telescopic rod, slide groove, first spring, movable plate, T-shaped reinforcement block, second spring, pulley, fixed pad, and push rod to coordinately move the heat shrink machine to a desired location. When the heat shrink machine needs to be carried, a worker can quickly lower the pulley and move it via the push rod, resulting in simple and convenient operation. Furthermore, the pulley can be effectively retracted when carried, and the fixed pad secures the heat shrink machine for stability, improving its practicality and work efficiency. However, in actual use, the above device does not have the function of adjusting the level of the machine body. For machines with mesh belt transmission, its tilted installation will cause the conveyor belt matched with it to be not level, resulting in deviation of materials during the transportation process. Utility Model Content
[0004] In order to make up for the above shortcomings, the utility model provides a heat shrink machine, which aims to improve the problem that the heat shrink machine in the prior art does not have the function of adjusting the level of the machine body, resulting in the deviation of materials during the transportation process.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a heat shrink machine, including a base, wherein the four corners of the bottom of the base are fixedly connected to cylinders, and the outer walls of multiple cylinders are provided with scale lines. The bottoms of multiple cylinders are fixedly connected to fixed blocks 1, the bottoms of multiple fixed blocks 1 are fixedly connected to springs, and the bottoms of multiple springs are fixedly connected to fixed blocks 2. The bottoms of multiple cylinders are provided with supporting legs, and the tops of multiple supporting legs are provided with grooves. The bottoms of the inner walls of multiple supporting legs are fixedly connected to electric telescopic rods, the bottoms of multiple fixed blocks 2 are fixedly connected to the tops of the electric telescopic rods, and the outer walls of multiple fixed blocks 1 and 2 are slidably connected to the inner sides of the supporting legs. The top of the base is fixedly connected to a heat shrink body, and the outer wall of the heat shrink body is provided with a heat dissipation mechanism.
[0006] The above technical solution, through the electrical connection between the electric telescopic rod and the controller, allows precise control of the height of each support leg. Combined with the scale lines on the outer wall of the cylinder, the operator can accurately determine the height adjustment of each support leg, thereby achieving precise horizontal adjustment of the heat shrink machine base, ensuring that the material does not shift during transportation and improving packaging quality. The spring between the first and second fixed blocks effectively buffers slight shaking caused by the weight of the machine itself or material movement during operation.
[0007] As a further description of the above technical solution:
[0008] The heat dissipation mechanism includes a heat dissipation plate, the outer wall of the heat dissipation plate is arranged on the front side of the outer wall of the heat shrink body, a heat dissipation port is opened on the front side of the outer wall of the heat shrink body, a mounting groove is opened on the inner side of the heat dissipation port, the outer wall of the heat dissipation plate is fixedly connected to the outer wall of the heat dissipation plate, the outer wall of the mounting ring is slidably connected to the inner side of the mounting groove, and a filter plate is arranged on the rear side of the heat dissipation plate.
[0009] Through the above technical solution: the heat sink is in close contact with the heat shrink body, quickly absorbing the heat generated by the heat shrink body during operation, ensuring its operation within the normal operating temperature range, and improving the working efficiency and stability of the heat shrink machine. The sliding connection design between the mounting ring and the mounting groove makes it very convenient to disassemble the heat sink and the filter plate. When the heat sink needs to be cleaned, repaired or replaced, the operator only needs to gently pull the heat sink, and the mounting ring can slide out of the mounting groove without the need for complex tools and tedious operating steps. This greatly saves maintenance time and cost and improves the maintainability of the heat shrink machine.
[0010] As a further description of the above technical solution:
[0011] The tops of the plurality of support legs are fixedly connected with a plurality of slide blocks, the outer walls of the plurality of cylinders are provided with a plurality of sliding grooves, and the outer walls of the slide blocks are slidably connected to the inner sides of the sliding grooves.
[0012] Through the above technical solution: the cooperation between the slider and the slide groove provides precise guidance for the support leg when it is adjusted up and down.
[0013] As a further description of the above technical solution:
[0014] The outer walls of the plurality of support legs are fixedly connected with reinforcement columns, and the bottoms of the plurality of support legs are fixedly connected with pads.
[0015] Through the above technical solution: the reinforcement columns fixedly connected to the outer walls of multiple support legs greatly enhance the structural strength of the support legs, and the pads can prevent the support legs from directly contacting the ground, preventing the support legs from scratching or damaging the ground.
[0016] As a further description of the above technical solution:
[0017] The outer wall of the base is fixedly connected with a controller, and the controller is electrically connected to the electric telescopic rod.
[0018] Through the above technical solution: the controller is electrically connected to the electric telescopic rod, so that the operator can directly and accurately control the telescopic action of the electric telescopic rod through the controller.

[0020] A conveyor belt is provided on the top of the base.
[0021] Through the above technical solution: a conveyor belt is arranged on the top of the base of the heat shrink machine, so that the material can be automatically transported.
[0022] As a further description of the above technical solution:
[0023] A heater is fixedly connected to the top of the heat shrink body, and transfer doors are provided on the left and right sides of the heat shrink body.
[0024] This technical solution enables the heater on top of the shrink unit to provide a stable and concentrated heat source for the shrinking process. The heat generated by the heater is quickly transferred to the shrink film on the surface of the material, causing it to shrink quickly and adhere tightly to the material, achieving efficient packaging. The transfer door acts as a barrier during the shrinking process, preventing operators from accidentally coming into contact with hot components within the shrink unit or the material being shrunk, thereby improving operational safety.
[0025] As a further description of the above technical solution:
[0026] The top of the base is fixedly connected with a gantry, and the front and rear sides of the gantry are both fixedly connected with fans.
[0027] Through the above technical solution: after the heat shrinkage of the object is completed, it passes through the gantry, and the fan on its outer wall takes away the heat of the object, making it cool down quickly.

[0030] 2. In the present invention, a filter plate is provided on the rear side of the heat sink, realizing an integrated design of filtering and heat dissipation. The filter plate can effectively prevent external dust and impurities from entering the interior of the heat shrink body, protecting the electronic components and mechanical parts inside the heat shrink body from contamination and damage.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0037] Refer to the attached Figure 1 and attached Figure 2 The utility model provides an embodiment: a heat shrink machine, including a base 1, the four corners of the bottom of the base 1 are fixedly connected to a cylinder 3, the outer walls of the multiple cylinders 3 are provided with scale lines 10, the bottoms of the multiple cylinders 3 are fixedly connected to a fixed block 4, the bottoms of the multiple fixed blocks 4 are fixedly connected to a spring 5, the bottoms of the multiple springs 5 are fixedly connected to a fixed block 2 6, the bottoms of the multiple cylinders 3 are provided with support legs 8, the tops of the multiple support legs 8 are provided with grooves 9, the bottoms of the inner walls of the multiple support legs 8 are fixedly connected to electric telescopic rods 7, the bottoms of the multiple fixed blocks 2 6 are fixedly connected to the electric At the top of the movable telescopic rod 7, the outer walls of multiple fixed blocks 1 4 and fixed block 2 6 are all slidably connected to the inner side of the support leg 8. The top of the base 1 is fixedly connected to a heat shrink body 13, and the outer wall of the heat shrink body 13 is provided with a heat dissipation mechanism 2; the outer wall of the base 1 is fixedly connected to a controller 14, and the controller 14 is electrically connected to the electric telescopic rod 7; a conveyor belt 19 is provided on the top of the base 1; a heater 18 is fixedly connected to the top of the heat shrink body 13, and a conveyor gate 20 is provided on the left and right sides of the heat shrink body 13; the top of the base 1 is fixedly connected to a gantry 16, and the front and rear sides of the gantry 16 are fixedly connected to fans 17;
[0038] Specifically, the controller 14 controls the telescopic action of the electric telescopic rod 7, and the horizontal state of the heat shrink machine can be accurately adjusted. The operator can easily operate the controller 14 according to actual needs to achieve independent adjustment of the height of each support leg 8, ensuring that the base 1 is completely level, improving the stability of the heat shrink machine during operation, and reducing problems such as material offset caused by tilting. The scale lines 10 on the outer wall of the cylinder 3 provide an intuitive reference standard for horizontal adjustment. During the adjustment process, the operator can accurately judge the height adjustment of each support leg 8, making the horizontal adjustment more scientific and standardized, and further improving the adjustment accuracy. The spring 5 plays a buffering and auxiliary adjustment role between the fixed block 1 4 and the fixed block 2 6. When the heat shrink machine is placed on an uneven ground, the spring 5 can be compressed and stretched to adjust the height. The slight shaking of the machine caused by its own weight or material movement is offset, so that the machine maintains a relatively stable state, and the adaptability of the heat shrink machine is improved. After the heat shrinkage of the item is completed, it passes through the gantry 16, and the fan 17 on its outer wall takes away the heat of the object, so that it cools down quickly. The conveyor belt 19 on the top of the base 1 can automatically transport the material to the heat shrink body 13, without the need for manual material handling, greatly improving production efficiency and reducing labor intensity. The conveying doors 20 on the left and right sides of the heat shrink body 13 facilitate the entry and exit of materials, making operation more convenient. The operator can easily place the material on the conveyor belt 19, and then enter the heat shrink body 13 through the conveying door 20 for heat shrink packaging, thereby improving work efficiency.
[0039] Refer to the attached Figure 3 The heat dissipation mechanism 2 includes a heat dissipation plate 201. The outer wall of the heat dissipation plate 201 is arranged on the front side of the outer wall of the heat shrink body 13. A heat dissipation port 203 is opened on the front side of the outer wall of the heat shrink body 13. A mounting groove 204 is opened on the inner side of the heat dissipation port 203. The outer wall of the heat dissipation plate 201 is fixedly connected to a mounting ring 202. The outer wall of the mounting ring 202 is slidably connected to the inner side of the mounting groove 204. A filter plate 205 is provided on the rear side of the heat dissipation plate 201.
[0040] Specifically, the heat dissipation vents 203 provide a channel for dissipating heat from within the heat shrink unit 13, increasing air circulation and improving heat dissipation efficiency. The heat dissipation vents 203 work in conjunction with the heat sink 201 to form an effective heat dissipation system, effectively discharging heat and preventing damage to internal components of the heat shrink unit 13 due to overheating. The sliding connection between the mounting ring 202 and the mounting slot 204 facilitates the removal and installation of the heat sink 201. When cleaning, repairing, or replacing the heat sink 201 and filter plate 205 is necessary, the operator can easily remove the heat sink 201 from the heat shrink unit 13 without the use of complex tools or tedious procedures, saving maintenance time and costs.
[0041] Refer to the attached Figure 1 The tops of the multiple support legs 8 are fixedly connected with multiple sliders 11, the outer walls of the multiple cylinders 3 are provided with multiple slide grooves 12, and the outer walls of the sliders 11 are slidably connected to the inner sides of the slide grooves 12; the outer walls of the multiple support legs 8 are fixedly connected with reinforcing columns 15, and the bottoms of the multiple support legs 8 are fixedly connected with pads 21.
[0042] Specifically, the sliders 11 on the tops of the multiple support legs 8 are slidably connected to the slide grooves 12 on the outer wall of the cylinder 3, providing a clear guide for the up and down movement of the support legs 8 during the horizontal adjustment of the heat shrink machine. This ensures that the support legs 8 can move vertically up and down without offset or shaking, making the height adjustment of the support legs 8 by the electric telescopic rod 7 more precise and stable, thereby ensuring the accuracy of the base 1 during horizontal adjustment. The reinforcing columns 15 fixedly connected to the outer walls of the multiple support legs 8 greatly enhance the structural strength of the support legs 8, and the pads 21 can prevent the support legs 8 from directly contacting the ground, preventing the support legs 8 from scratching or damaging the ground.
[0043] Working principle: the material is placed on the conveyor belt 19, and the conveyor belt 19 transports the material into the heat shrink machine body 13. The top of the heat shrink machine body 13 is fixedly connected with a heater 18. The heater 18 heats the material to shrink the heat shrink film on the surface of the material, thereby realizing the packaging of the material. When the heat shrink machine needs to be adjusted horizontally, the operator sends an instruction through the controller 14. The controller 14 is electrically connected to the electric telescopic rod 7 to control the telescopic action of the electric telescopic rod 7. When the electric telescopic rod 7 is extended or retracted, it will drive the fixed block 2 6 to move up and down. Due to the connection effect of the spring 5, the fixed block 1 4 will also slide up and down on the inside of the support leg 8. At the same time, by observing the scale line 10 on the outer wall of the cylinder 3, the height adjustment of each support leg 8 can be accurately judged. In the initial state, the spring 5 is squeezed to the deepest state, the electric telescopic rod 7 remains at the highest, and its support leg 8 is at the lowest. The top is maintained at the zero position at the bottom of the scale line 10. Later, due to different pressures, the base 1 will tilt. At this time, the length of each electric telescopic rod 7 can be adjusted separately to make the base 1 reach a horizontal state. Through the spring 5 arranged between the fixed block 1 4 and the fixed block 2 6, when the heat shrink machine is placed on an uneven ground, it will produce slight shaking due to the weight of the machine itself or the movement of the material. The spring 5 can offset these shaking by compression and extension, so that the machine remains in a relatively stable state. In addition, the heat shrink body 13 will generate a lot of heat when working. This heat will increase the temperature inside the heat shrink body 13. In order to maintain the normal operating temperature of the heat shrink body 13, this heat needs to be dissipated. The setting of the heat dissipation port 203 provides a dissipation channel for the heat inside the heat shrink body 13, and a filter plate 205 is provided on the rear side of the heat sink 201. Prevent external dust and impurities from entering the interior of the heat shrink body 13. At the same time, the heat sink 201 can be disassembled through the sliding connection between the mounting ring 202 and the mounting groove 204. When the heat sink 201 needs to be disassembled for maintenance, cleaning or replacement, the operator applies an outward pulling force to the heat sink 201, and the mounting ring 202 will gradually slide out of the mounting groove 204, so that the filter plate 205 inside it can be cleaned.
[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
