Description

Technical Field

[0001] This utility model relates to the field of transparent lunch box processing technology, specifically a heat shrink machine for processing disposable transparent lunch boxes. Background Technology

[0002] The principle of heat shrink packaging is to use the shrinkage force generated by thermoplastic film when heated to tightly wrap the food container, thereby achieving the purposes of sealing, moisture prevention, and pollution prevention. In this process, the heat shrink machine plays a crucial role.

[0003] However, traditional heat shrink machines of this type have many shortcomings. The layout of their heating points is fixed at the beginning of the equipment design and cannot be flexibly changed. This fixedness makes them inadequate when dealing with transparent lunch boxes of different sizes and shapes. When heat shrinking the plastic film of the lunch box, because the heating points cannot be dynamically adjusted, the heat cannot be evenly covered on the entire surface of the plastic film. These uneven shrinkage directly cause unsightly wrinkles and air bubbles to appear on the lunch box packaging. This not only greatly reduces the visual effect of the packaging and worsens the consumer's first impression, but also damages the integrity and airtightness of the packaging, making it unable to effectively isolate the external environment and providing the possibility for the growth of microorganisms. Ultimately, this leads to a decline in product quality and adversely affects the company's reputation and profits. Therefore, there is an urgent need for a heat shrink machine for processing disposable transparent lunch boxes to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a heat shrink machine for processing disposable transparent lunch boxes, so as to solve the problem mentioned in the background art that traditional heat shrink machines for processing transparent lunch boxes are difficult to heat the shrink film evenly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat shrink machine for processing disposable transparent lunch boxes, comprising a main frame, a uniform heating component provided on the top surface of the main frame, and a linkage component rotatably connected to the inner wall of the main frame;

[0006] The uniform heating component includes a heating barrel disposed on the top surface of the uniform heating component. The surface of the heating barrel has multiple toothed grooves, and the inner wall of each toothed groove has an installation groove. A heating element is fixedly connected to the inner wall of the installation groove. A fixing plate is fixedly connected to the surface of the heating barrel, and a heater is fixedly connected to the bottom surface of the fixing plate. Both ends of the heating element are fixedly connected to the inner wall of the heater. An installation block is fixedly connected to the bottom surface of the main frame. A rotating column is rotatably connected to the inner wall of the installation block. A gear disk is fixedly connected to the surface of the rotating column, and the surface of the gear disk meshes with the inner wall of the toothed groove. A limit groove is formed on the surface of the heating barrel.

[0007] In this technical solution, by setting up a uniform heating component, when a disposable transparent lunch box with its plastic seal film enters the inner wall of the uniform heating component, the inner wall of the mounting slot is equipped with a heating element. At the same time, the uniform heating component rotates to achieve comprehensive and uniform heating of the surrounding area of ​​the transparent lunch box with its plastic seal film, avoiding problems such as wrinkles and bubbles on the surface of the lunch box packaging, improving the aesthetics and sealing of the packaging and the overall quality of the product. Meanwhile, the heating barrel is made of fiberglass, which can effectively prevent heat conduction, thereby preventing heat loss from the heating element.

[0009] In this technical solution, the linkage components are designed so that when the conveyor belt rotates, the connecting column can be driven to rotate by the cooperation of the first bevel gear, the second bevel gear and the third bevel gear. The rotation of the connecting column can drive the rotating column to rotate by the cooperation of the synchronous pulley and the belt. When the rotating column rotates, the heating barrel can be driven to rotate by the cooperation of the gear disc and the tooth groove. This saves energy and improves the synchronization and linkage of the overall operation.

[0010] Preferably, a positioning block is fixedly connected to the bottom surface of the main frame, a rotating column is rotatably connected to the inner wall of the positioning block, a rotating disk is fixedly connected to the surface of the rotating column, and the surface of the rotating disk abuts against the inner wall of the limiting groove.

[0011] In this technical solution, the limiting groove and positioning block work together to limit the rotation column and support the heating barrel so that the heating barrel is parallel to the main frame, thus facilitating the rotation of the heating barrel when the gear disc rotates.

[0012] Preferably, the inner wall of the heating barrel is provided with a fixing groove, and a heat conduction plate is fixedly connected to the inner wall of the fixing groove. The heat conduction plate is made of chromium metal.

[0013] In this technical solution, the heat conduction plate made of chromium metal is designed to provide good thermal conductivity and improve the molding efficiency.

[0014] Preferably, a protective box is fixedly connected to the bottom surface of the fixing plate, and clearance holes are provided on both sides of the protective box. The inner wall of the clearance hole is fixedly connected to the surface of the heating tube.

[0016] Preferably, the surface of the first bevel gear meshes with the surface of the second bevel gear, and the surface of the second bevel gear meshes with the surface of the third bevel gear.

[0017] In this technical solution, the first bevel gear, the second bevel gear, and the third bevel gear work together to make the rotating shaft rotate, which in turn drives the connecting column to rotate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] By setting up a uniform heating component, when a disposable transparent lunchbox with its plastic seal film enters the inner wall of the uniform heating component, the inner wall of the mounting slot is equipped with heating tubes. At the same time, the uniform heating component rotates, thereby achieving comprehensive and uniform heating of the surrounding area of ​​the transparent lunchbox with its plastic seal film. This avoids problems such as wrinkles and bubbles on the surface of the lunchbox packaging, improving the aesthetics and sealing of the packaging and the overall quality of the product. Through the setting of a linkage component, when the rotating column rotates, the heating barrel can be driven to rotate through the interaction of the gear plate and the tooth groove, thereby saving energy consumption and improving the synchronization and linkage of the overall operation.

The surface of the heating barrel 201 has a limiting groove 214. By setting the uniform heating component 2, when the disposable transparent lunch box with plastic sealing film enters the inner wall of the uniform heating component 2, the inner wall of the mounting groove 203 is provided with a heating tube 204. At the same time, the uniform heating component 2 rotates to achieve comprehensive and uniform heating of the transparent lunch box with plastic sealing film around its perimeter, avoiding problems such as wrinkles and bubbles on the surface of the lunch box packaging, improving the aesthetics and sealing of the packaging and the overall quality of the product. Meanwhile, the heating barrel 201 is made of glass fiber material, which can effectively prevent heat conduction, thereby preventing heat loss from the heating tube 204.

[0027] Furthermore, the linkage component 3 includes a conveyor belt 301, which is rotatably connected to the inner wall of the main frame 1. A rotating shaft 302 is fixedly connected to the inner wall of the conveyor belt 301. A first bevel gear 303 is fixedly connected to the surface of the rotating shaft 302. A second bevel gear 304 is rotatably connected to the inner wall of the main frame 1. A connecting block 305 is fixedly connected to the bottom surface of the main frame 1. A connecting column 306 is rotatably connected to the inner wall of the connecting block 305. A third bevel gear 307 is fixedly connected to the surface of the connecting column 306.

Through the linkage component 3, when the conveyor belt 301 rotates, the first bevel gear 303, the second bevel gear 304 and the third bevel gear 307 work together to drive the connecting column 306 to rotate. The rotation of the connecting column 306, through the interaction of the synchronous pulley 308 and the belt 309, drives the rotating column 210 to rotate. When the rotating column 210 rotates, through the interaction of the gear disc 211 and the tooth groove 202, the heating barrel 201 rotates, thereby saving energy and improving the synchronization and linkage of the overall operation.

[0031] Furthermore, the surface of the first bevel gear 303 meshes with the surface of the second bevel gear 304, and the surface of the second bevel gear 304 meshes with the surface of the third bevel gear 307. By using the first bevel gear 303, the second bevel gear 304 and the third bevel gear 307 in cooperation with each other, the rotation of the rotating shaft 302 can drive the connecting column 306 to rotate.

[0032] Working principle: By setting up a uniform heating component 2, when a disposable transparent lunch box with its plastic seal film enters the inner wall of the uniform heating component 2, the inner wall of the mounting groove 203 is equipped with a heating element 204. Simultaneously, the uniform heating component 2 rotates, achieving comprehensive and uniform heating of the entire periphery of the transparent lunch box with its plastic seal film. This avoids problems such as wrinkles and bubbles on the surface of the lunch box packaging, improving the aesthetics and sealing of the packaging, as well as the overall quality of the product. Furthermore, the heating barrel 201 is made of fiberglass, which effectively prevents heat conduction, thus avoiding the heating element... The heat loss generated by 204 is mitigated by the linkage component 3, which enables the connecting column 306 to rotate when the conveyor belt 301 rotates through the interaction of the first bevel gear 303, the second bevel gear 304, and the third bevel gear 307. The rotation of the connecting column 306, in turn, drives the rotating column 210 to rotate through the interaction of the synchronous pulley 308 and the belt 309. When the rotating column 210 rotates, the heating tank 201 rotates through the interaction of the gear disc 211 and the tooth groove 202. This process saves energy and improves the synchronization and linkage of the overall operation.
