They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figures 1 to 3As shown, the heat-sealing packaging equipment of this utility model includes a conveying mechanism 10 and a film-coating heat-shrinking mechanism 20 disposed above the conveying mechanism 10; the conveying mechanism 10 is provided with a negative pressure generating mechanism 30; the film-coating heat-shrinking mechanism 20 includes a movable support 21, lifting drive components 22 disposed on both sides of the movable support 21, an unwinding component 23 disposed at one end of the movable support 21, and material gripping components 24 disposed on both sides of the movable support 21; the inner side of the movable support 21 is provided with a plurality of heating tubes 211 arranged at equal intervals, the lifting drive component 22 is used to drive the movable support 21 to move vertically up and down; the material gripping component 24 is used to grip and pull out the heat-shrinking film in the unwinding component 23.

[0028] In practical applications, the conveying mechanism 10 is covered with a bottom film, and the product to be packaged is placed on top of the bottom film. The unwinding assembly 23 unwinds the heat shrink film, and the gripping assembly 24 clamps the heat shrink film and pulls it away from the unwinding assembly 23, so that the heat shrink film covers the bottom of the movable support 21. Subsequently, the lifting drive assembly 22 drives the movable support 21 to move down, so that the heat shrink film covers the top of the product. The negative pressure generating mechanism 30 is activated to create negative pressure between the heat shrink film and the bottom film, so that the product is wrapped between the heat shrink film and the bottom film. At the same time, the heating tube 211 heats up, causing the heat shrink film to shrink and connect with the bottom film, completing the heat-sealing packaging of the product.

[0029] Specifically, the conveying mechanism 10 includes a support 11 and multiple conveying rollers 12 rotatably connected to the inner side of the support 11. The negative pressure generating mechanism 30 includes a vacuum generator 31 located below the conveying mechanism 10. The vacuum generator 31 extends with a negative pressure tube 32, the other end of which communicates with the conveying mechanism 10, specifically connected to the inner side of the support 11. The bottom film is located at the upper end of the conveying rollers 12, and a gap is left between the edge of the bottom film and the edge of the support 11. In addition, the width of the heat shrink film is larger than that of the bottom film. After the heat shrink film is covered on the product, the vacuum generator 31 is activated to create negative pressure between the heat shrink film and the bottom film, so that the heat shrink film and the bottom film adhere to each other, ensuring the packaging is airtight.

[0030] Specifically, the lifting drive assembly 22 includes a lifting cylinder 221, which is located at the bottom of the movable bracket 21. The lifting cylinder 221 is used to drive the movable bracket 21 to move vertically up and down, and has a fast response speed. In addition, the lifting drive assembly 22 also includes guide sleeves 222 fixed to both sides of the transmission mechanism 10 and guide posts 223 fixed to the lower end of the movable bracket 21. The guide posts 223 are inserted into the guide sleeves 222, and the guide posts 223 cooperate with the guide sleeves 222 to ensure the vertical movement of the movable bracket 21, thereby preventing the heat shrink film from shifting.

[0031] Specifically, the unwinding assembly 23 includes an unwinding roller group and a cutting module disposed on one side of the unwinding rollers. The unwinding roller group is used for unwinding the heat shrink film, and the cutting module is used for cutting the heat shrink film. The unwinding roller group includes an unwinding motor 231, an unwinding shaft 232, and multiple transition rollers 233. The unwinding motor 231 is drivenly connected to the unwinding shaft 232. The transition rollers 233 are disposed on the side of the unwinding shaft 232 facing the cutting module. The heat shrink film is wound around the outside of the unwinding shaft 232, and one end passes over multiple transition rollers 233 in sequence. The cutting module includes a linear module 234, a slider 235 driven and connected to the linear module 234, and a cutting tool 236 fixed to the lower end of the slider 235. When the heat shrink film extends to a sufficient length, the linear module 234 drives the slider 235 to move horizontally, so as to drive the cutting tool 236 to cut the heat shrink film. The cutting module also includes a pressing cylinder (not shown), a pressing block 238, and a support platform 239. The pressing cylinder is located below the linear module 234, the pressing block 238 is fixed to the lower end of the pressing cylinder, and the support platform 239 is located below the pressing block 238. The pressing cylinder drives the pressing block 238 to move downward to press the heat shrink film onto the support platform 239 to ensure the stability of subsequent cutting.

[0032] Specifically, the material gripping assembly 24 includes sliding modules 241 disposed on both sides of the movable bracket 21, and grippers 242 driven and connected to the sliding modules 241; in this embodiment, the grippers 242 are pneumatic grippers 242. During operation, the grippers 242 clamp one end of the heat shrink film, and the sliding modules 241 drive the grippers 242 to move away from the unwinding assembly 23, thereby pulling out the heat shrink film. The structure is reasonably designed; at the same time, the use of two sets of sliding modules 241 and grippers 242 can prevent the heat shrink film from shifting.

[0033] Compared to existing technologies, the heat-sealing packaging equipment of this utility model includes a transmission mechanism 10 and a film-coating heat-shrinking mechanism 20. The transmission mechanism 10 is equipped with a negative pressure generating mechanism 30, which can generate negative pressure between the heat-shrink film and the base film. At the same time, the high temperature of the heating tube 211 is used to heat-seal the product between the heat-shrink film and the base film. This method has a high degree of automation, improves heat-sealing efficiency and quality, and meets the requirements of the modern packaging industry. In addition, the film-coating heat-shrinking mechanism 20 includes a movable support 21, a lifting drive assembly 22, an unwinding assembly 23, and a material gripping assembly 24. The material gripping assembly 24 pulls out the heat-shrink film in the unwinding assembly 23 and covers the bottom of the movable support 21. The lifting drive assembly 22 drives the movable support 21 to move down and covers the top of the product with the pulled-out heat-shrink film to facilitate subsequent negative pressure heat-sealing packaging, improve packaging efficiency, and adapt to various product sizes. The material gripping assembly 24 is used to pull out the heat-shrink film to avoid jamming and deviation, thus improving the heat-sealing packaging quality.

[0034] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
