Description

Technical Field

[0001] This utility model relates to the field of heat shrink packaging machine technology, and in particular to a heat shrink packaging machine with a dustproof structure. Background Technology

[0002] A heat shrink packaging machine is a device that uses a conveyor belt to transport products and heats them in a heating chamber to shrink and bond the outer heat shrink film of the product. The core principle is to use the thermoplasticity of the heat shrink film to achieve packaging through heating, shrinking and shaping. It is widely used in many industries.

[0003] Existing equipment has dustproof curtains installed at the inlet and outlet of the heating chamber. However, gaps are created in the curtains when products pass through, allowing external dust to be brought in with the products. Furthermore, the shaking of the curtains can cause attached dust to fall off and enter the heating chamber. Dust adhering to the heating components will reduce heating efficiency, contaminate the products and affect packaging quality, and also interfere with hot air circulation, resulting in uneven shrinkage. In view of this, this application proposes a heat shrink packaging machine with a dustproof structure. Utility Model Content

Each first dust filter box is connected to the suction end of the first fan. Each first dust filter box is equipped with multiple first dust filter plates. Each first dust filter box is connected to a corresponding dust collection seat. The exhaust end of each first fan is connected to the corresponding blower seat through a connecting pipe.

[0007] Preferably, two side plates are symmetrically installed on the inner wall of each extension channel near the heating chamber, and the two side plates are symmetrically inclined. A cleaning roller is rotatably connected to one end of each side plate.

[0008] Preferably, the hot air circulation assembly includes two hoods, which are respectively installed on the two side walls of the heating chamber.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] This utility model provides a technical solution: such as Figure 1-4As shown, a heat shrink packaging machine with a dustproof structure includes a conveyor frame 1, a conveyor belt 2 mounted on the top surface of the conveyor frame 1, a heating chamber 3 mounted on the top surface of the conveyor frame 1, and extension channels 4 fixed and connected to both outer sides of the heating chamber 3. Each extension channel 4 is equipped with an air curtain dust-blocking assembly, and each air curtain dust-blocking assembly includes two dustproof and heat-insulating curtains 5, with each pair of dustproof and heat-insulating curtains 5 respectively installed on the two outer sides of the extension channel 4. Dust suction devices are fixedly installed on the corresponding inner walls on both sides of each extension channel 4. The vacuum cleaner seat 9 and the blower seat 10 are provided with several micro-holes 12 on their outer sides. Multiple circulating blower dust removal mechanisms are installed on the outer side of the conveyor frame 1, and each circulating blower dust removal mechanism is connected to the corresponding vacuum cleaner seat 9 and blower seat 10. A heating component is installed in the heating chamber 3, and the heating component is used to heat the air in the heating chamber 3. A hot air circulation component is installed on the outer side of the heating chamber 3. A dehumidification and dust removal component is installed on the top surface of the heating chamber 3, and the dehumidification and dust removal component is connected to the hot air circulation component.

[0017] Furthermore, each circulating blower dust removal mechanism includes a first dust filter box 6 and a first blower 7, and each first dust filter box 6 and the first blower 7 are respectively installed on the outside of the conveyor frame 1, and each first dust filter box 6 is connected to the suction end of the first blower 7. Each first dust filter box 6 is equipped with multiple first dust filter plates 8, and each first dust filter box 6 is connected to the corresponding dust suction seat 9. The exhaust end of each first blower 7 is connected to the corresponding blower seat 10 through a connecting pipe 11. The circulating blower dust removal mechanism enables the air in each extension channel 4 to flow in a directional manner, forming an air curtain. The air is discharged from the blower seat 10 and sucked in through the dust suction seat 9. The circulating air blows away the dust and other impurities on the film covering the outside of the product and the outside of the product, and filters them through the first dust filter plate 8 in the first dust filter box 6. This reduces the amount of dust and other impurities brought into the heating chamber 3 by the product and the product film. At the same time, the dustproof and heat insulation curtains 5 on both sides of each extension channel 4 can prevent external dust from entering the extension channel 4 and prevent the dust in the extension channel 4 from entering the heating chamber 3. Furthermore, two side plates 13 are symmetrically installed on the inner wall of each extension channel 4 near the heating chamber 3, and the two side plates 13 are symmetrically inclined. A cleaning roller 14 is rotatably connected to one end of each side plate 13. It should be noted that the two side plates 13 are inverted octagonal, and the cleaning roller 14 can clean dust and other impurities on the outside of the product film. As the product moves, a relatively closed space is formed between the side plates 13, the product, and the extension channel 4. By guiding the flow through the inclined side plates 13, the wind can be prevented from directly passing through the dustproof and heat insulation curtain 5 into the heating chamber 3.

[0018] Furthermore, the hot air circulation assembly includes two hoods 20, which are respectively installed on the two side walls of the heating chamber 3. A second fan 19 is installed on the top surface of the heating chamber 3. The exhaust end of the second fan 19 is connected to the corresponding hood 20 through the exhaust pipe 22, and the intake end of the second fan 19 is connected to the other hood 20.

[0019] Furthermore, the dehumidification and dust removal assembly includes a dehumidification box 15 and a second dust filter box 16, both of which are installed on the top surface of the heating chamber 3 and are connected to each other. The dehumidification box 15 contains a plurality of activated carbon plates 18, and the second dust filter box 16 contains a plurality of second dust filter plates 17. One of the fan hoods 20 is connected to the second dust filter box 16 through a return pipe 21, and the suction end of the second fan 19 is connected to the dehumidification box 15. The activated carbon plate 18 and the second dust filter plate 17 enable the air in the heating chamber 3 to form a self-cleaning circulation, reducing the introduction of outside air and thus achieving a dust prevention effect. They also reduce the introduction of outside humid air, ensuring the coating effect.

[0020] Furthermore, the heating assembly includes two mounting brackets 23, which are respectively installed on the inner walls of the two sides of the heating chamber 3. Each mounting bracket 23 has multiple through slots 24 on its outer side, and multiple heating tubes 25 are installed in each mounting bracket 23.

[0021] This utility model provides a heat shrink packaging machine with a dustproof structure, and its specific working principle is as follows: First, the product to be packaged, covered with heat shrink film, is placed on the conveyor belt 2 of the conveyor frame 1. After the conveyor belt 2 is started, it moves the product towards the heating chamber 3 and first enters the feed side extension channel 4. At this time, the dustproof and heat insulation curtain 5 on the outside of the extension channel 4 first blocks the external dust, and at the same time the circulating blower dust removal mechanism is started. The first fan 7 draws air through the micro-holes 12 of the dust suction seat 9 and exhausts air through the micro-holes 12 of the blower seat 10, so that a directional airflow curtain is formed in the channel, blowing away impurities on the product and film surface and sucking them into the dust suction seat 9. The airflow is filtered by the first dust filter plate 8 in the first dust filter box 6 and then circulated. At the same time, the dustproof and heat insulation curtain 5 on the other side blocks dust and other impurities in the extension channel 4 from entering the heating chamber 3. As the product continues to move, it is guided by the inverted octagonal side plate 13, and the cleaning rollers 14 on both sides rotate with the product to further clean the dust on the film surface. The side plate 13 also forms a relatively closed space to prevent airflow from entering the heating chamber 3. After the product enters the heating chamber 3, the heating tube 25 in the fixing frame 23 is energized and heats up. The heat is evenly diffused through the channel 24 and the temperature rises. The second fan 19 is started to circulate the hot air. Some of the hot air enters the second dust filter box 16 through the air hood 20 and the return pipe 21. After being filtered by the second dust filter plate 17, it enters the dehumidification box 15. The activated carbon plate 18 adsorbs the moisture. After purification, it is drawn back by the second fan 19 and sent back to the heating chamber 3 through the exhaust pipe 22. After the film is heated and shrinks to fit the product, it is discharged through the discharge side extension channel 4. The dustproof wind curtain component on this side provides further protection to prevent external dust from entering the heating chamber 3, thus completing the dustproof heat shrink packaging.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
