[0033] like Figures 1 to 4 As shown, this utility model discloses a lamination and cutting system for covering and cutting a bottom film with a top film. Specifically, the product is placed on the bottom film, and the top film covers both the product and the bottom film. Heat sealing causes the top film to shrink and adhere to the bottom film, thereby packaging the product between the top and bottom films. The aforementioned lamination and cutting system includes a lamination unit 100 and a cutting unit 200.

[0034] Please see Figure 3 and Figure 4 The laminating unit 100 includes a first conveying mechanism 70 and a laminating mechanism disposed above the first conveying mechanism 70. The laminating mechanism includes a movable support 10, lifting drive assemblies 20 disposed on both sides of the movable support 10, an unwinding assembly 30 disposed at one end of the movable support 10, and material gripping assemblies 40 disposed on both sides of the movable support 10. Multiple heating tubes 11 arranged at equal intervals are provided on the inner side of the movable support 10. During operation, the unwinding assembly 30 is used to unwind the top film, and the material gripping assembly 40 is used to grip the top film and pull it to the lower end of the movable support 10. The lifting drive assembly 20 drives the movable support 10 downward, covering the product and the bottom film with the top film. Simultaneously, under the high temperature of the heating tubes 11, the top film shrinks and adheres to the bottom film. The first conveying mechanism 70 is a conveyor line.

[0035] Specifically, the lifting driving assembly 20 comprises a jacking cylinder arranged at the bottom of the movable support 10, and the jacking cylinder drives the movable support 10 to vertically lift; the lifting driving assembly 20 further comprises a guide sleeve 22 fixed to both sides of the transmission mechanism and a guide column 21 fixed to the lower end of the movable support 10; the guide column 21 is inserted into the guide sleeve 22. The jacking cylinder is used to drive the movable support 10 to vertically lift, and the bearing effect is good and the response speed is fast; meanwhile, the guide column 21 cooperates with the guide sleeve 22 to ensure the vertical lifting of the movable support 10, thereby avoiding the deviation of the top film cover and ensuring the packaging precision.

[0036] Specifically, the unwinding assembly 30 comprises an unwinding roller set 31 and a cutting die set 32 arranged at one side of the unwinding roller set 31, the unwinding roller set 31 is used for unwinding the top film, and the cutting die set 32 is used for cutting the top film. The unwinding roller set 31 comprises an unwinding motor 311, an unwinding shaft 312 and a plurality of transition rollers 313, the unwinding motor 311 is drivingly connected with the unwinding shaft 312, the transition rollers 313 are arranged at the side of the unwinding shaft 312 facing the cutting die set 32, the top film in a roll is wound outside the unwinding shaft 312, and one end of the top film sequentially passes through the transition rollers 313, the unwinding motor 311 drives the unwinding shaft 312 to rotate, so as to realize the unwinding of the top film. The cutting die set 32 comprises a linear die set 321, a sliding block 322 drivingly connected with the linear die set 321, and a cutting tool 323 fixed to the lower end of the sliding block 322; after the heat sealing packaging is completed, the linear die set 321 drives the sliding block 322 to slide, and drives the cutting tool 323 to draw across the top film, so that the top film is separated from the unwinding assembly 30. Further, the cutting die set 32 further comprises a pressing cylinder (not shown in the figure), a pressing block 325 and a support table 326; the pressing cylinder is arranged below the linear die set 321, the pressing block 325 is fixed to the lower end of the pressing cylinder, and the support table 326 is arranged below the pressing block 325; when the top film is cut, the pressing cylinder drives the pressing block 325 to move downward, so as to press the top film on the support table 326, thereby avoiding the shaking of the top film in the cutting process and affecting the cutting precision.

[0037] Specifically, the grabbing assembly 40 comprises a sliding die set 41 arranged at both sides of the movable support 10 and a clamping jaw 42 drivingly connected with the sliding die set 41; in this embodiment, the clamping jaw 42 is a pneumatic clamping jaw 42. When working, the clamping jaw 42 clamps one end of the heat shrinkable film, the sliding die set 41 drives the clamping jaw 42 to move away from the unwinding assembly 30, thereby pulling out the heat shrinkable film, and the structure is reasonably arranged; meanwhile, two groups of sliding die sets 41 and clamping jaws 42 are adopted, so as to avoid the deviation of the heat shrinkable film.

[0038] Please refer to Figure 1 and Figure 2The cutting unit 200 comprises a second conveying mechanism 50 connected with the first conveying mechanism 70 and a cutting mechanism 60 arranged above the second conveying mechanism 50, wherein the cutting mechanism 60 comprises a Y-axis driving module 61, a supporting beam 62 drivingly connected with the Y-axis driving module 61, an X-axis driving module 63 fixed to the upper end of the supporting beam 62, a Z-axis driving module 64 drivingly connected with the X-axis driving module 63, and a cutter head 65 fixed to the Z-axis driving module 64. The Y-axis driving module 61, the X-axis driving module 63 and the Z-axis driving module 64 drive the cutter head 65 to move, and the cutter head 65 cuts around the product to separate the packaged finished product, wherein the Y-axis driving module 61, the X-axis driving module 63 and the Z-axis driving module 64 are all linear modules 321, which have high response speed and high moving precision, thereby ensuring the cutting precision of the cutter head 65.

[0039] The second conveying mechanism 50 is a conveying line, and further comprises a suction bottom plate provided with a plurality of suction holes on the upper end face, and a vacuum generator communicated with the suction bottom plate, so that negative pressure is generated on the suction bottom plate to suck and hold the product during the cutting process, thereby avoiding shaking during the cutting process. In addition, a visual sensor is arranged above the cutting unit 200 and electrically connected with the cutting unit 200, so as to ensure the cutting position of the cutting unit 200.

[0040] The working principle of the film cutting system is as follows: the bottom film is covered on the first conveying mechanism 70 and the second conveying mechanism 50, and the product is placed on the bottom film. The film grabbing assembly 40 pulls out the top film in the unwinding assembly 30, so that the top film is covered on the lower end of the movable support 10. The lifting driving assembly 20 drives the movable support 10 to press down, and then the top film is covered on the product and the bottom film. At the same time, under the high temperature action of the heating pipe 11, the top film shrinks and is bonded with the bottom film, so that the product is wrapped between the top film and the bottom film. Then, the product is fed into the second conveying mechanism 50, and the cutting mechanism 60 cuts to separate the finished product.

[0041] Compared with the prior art, the film cutting system is used for product packaging and cutting, and is provided with a film covering unit 100 and a cutting unit 200. The film covering unit 100 comprises a movable support 10, a lifting driving assembly 20, an unwinding assembly 30 and a film grabbing assembly 40. The film grabbing assembly 40 is used for clamping and pulling the top film unwound from the unwinding assembly 30 to the lower end of the movable support 10. Then, the lifting driving assembly 20 drives the movable support 10 to move downward, and then the top film is covered on the bottom film and the product. After the heat sealing packaging is completed, the cutting unit 200 cuts through the automatic mechanical equipment. The mechanical structure and the processing steps are reasonable and efficient, which helps to improve the quality and efficiency of product packaging and meets the needs of large-scale packaging industry.

[0042] The above merely expresses the preferred technical solutions of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the application. It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and the present application also intends to include these changes and modifications.
