[0026] The side of the support frame 1 is equipped with film roll releasing mechanism 2, and the film pulled out by the film roll releasing mechanism 2 is located on the surface of support frame 1.The film roll releasing mechanism 2 includes roll releasing support plate 21, film placing shaft 22 and tensioning support shaft 23, the side of roll releasing support plate 21 is equipped with film placing shaft 22 and several tensioning support shafts 23 for tensioning film, and each tensioning support shaft 23 can rotate relative to roll releasing support plate 21.

[0027] Film is pulled by external traction equipment, and is covered on material to be vacuum packaged on the surface of support frame 1.The surface of film placing shaft 22 is wound with film, and the surface of film placing shaft 22 rotates to realize continuous material release in the process that film is continuously pulled.In the process of material release, tensioning support shaft 23 plays the role of support and guide.

[0028] The inside of the support frame 1 is provided with a lifting mechanism 4. The lifting mechanism 4 comprises a lifting base 41, a first lifting support plate 42, a second lifting support plate 43, a lifting top cover 44, a lifting drive shaft 45 and a hydraulic oil cylinder 46. The inside of the lifting base 41 is respectively hingedly connected to one end of the first lifting support plate 42 and the second lifting support plate 43 on the left and right sides. The middle part of the first lifting support plate 42 and the second lifting support plate 43 is hingedly connected, and the top part is respectively hingedly connected to the lifting top cover 44. The adjacent second lifting support plates 43 are provided with the lifting drive shaft 45. The lifting drive shaft 45 is pushed by the piston rod of the hydraulic oil cylinder 46 to change the position, and the change of the position of the lifting drive shaft 45 drives the change of the included angle between the first lifting support plate 42 and the second lifting support plate 43.

[0029] When the height of the lifting top cover 44 needs to be adjusted, the piston rod of the hydraulic oil cylinder 46 pushes the lifting drive shaft 45 to generate an upward driving force. At this time, the middle part of the first lifting support plate 42 and the second lifting support plate 43 is hingedly rotated, and the two ends of the first lifting support plate 42 and the second lifting support plate 43 are also respectively rotated relative to the lifting base 41 and the lifting top cover 44. Gradually, the included angle between the first lifting support plate 42 and the second lifting support plate 43 changes, and then the height of the lifting top cover 44 changes.

[0030] In this embodiment, the surface of the lifting mechanism 4 is provided with a film shearing mechanism 3. The inside of the film shearing mechanism 3 is provided with a material collecting mechanism 6 for holding the sheared material.

[0031] The film shearing mechanism 3 comprises a shearing support frame 31, a rectangular knife plate 32 and a blanking guide plate 33. The surface of the shearing support frame 31 is provided with a plurality of rectangular knife plates 32 for shearing the film. The inside of the rectangular knife plate 32 can allow the end of the material collecting mechanism 6 to pass up and down. The side of the shearing support frame 31 close to the conveying mechanism 5 is also provided with a blanking guide plate 33.

[0032] The material collecting mechanism 6 comprises a first air cylinder 61, a material support frame 62 and a material supporting block 63. The bottom of the lifting top cover 44 is provided with a first air cylinder 61. The end of the first air cylinder 61 is connected with the material support frame 62 through the surface of the lifting top cover 44. The surface of the material support frame 62 is provided with a plurality of material supporting blocks 63. The height of the material support frame 62 changes with the change of the height of the piston rod of the first air cylinder 61.

[0033] The height change of the lifting top cover 44 will simultaneously cause the height change of the shearing support frame 31, until the rectangular blade 32 can shear the film upward. In the shearing process, the first cylinder 61 drives the material supporting block 63 to move upward appropriately, so that the rectangular blade 32 can complete the shearing operation. The surface of the sheared material is still attached to the film under vacuum, and falls on the surface of the material supporting block 63 in the middle of the rectangular blade 32. Then the height of the whole lifting top cover 44, the film shearing mechanism 3 and the material collecting mechanism 6 gradually falls.

[0034] The material supporting block 63 is hollow inside and provided with suction holes 631 on the surface, and a vacuum pipe 64 is connected to the side wall of the material supporting block 63 and connected to an external vacuum pump.

[0035] After the material supporting block 63 contacts the material, the first cylinder 61 drives the surface of the material supporting block 63 to firmly adhere to the bottom of the material, and then the external vacuum pump uses the vacuum pipe 64 to firmly suck the material through the suction holes 631. The rectangular blade 32 does not displace the material during shearing, and the sheared material does not fall and slide to other positions.

[0036] In the embodiment, one side of the material collecting mechanism 6 is provided with a material pushing mechanism 7 capable of pushing the material to the conveying mechanism 5. The inside of the support frame 1 is also provided with a conveying mechanism 5, and the material pushing mechanism 7 comprises a material pushing support plate 71, a second cylinder 72 and a material pushing plate 73. The surface of the material pushing support plate 71 is provided with the second cylinder 72, the end of the piston rod of the second cylinder 72 is provided with the material pushing plate 73, and the width of the material pushing plate 73 is greater than the sum of the widths of the plurality of material supporting blocks 63.

[0037] The conveying mechanism 5 comprises a conveying belt 51, a conveying drive shaft 52 and a driving motor 53. The inside of the support frame 1 is rotatably connected with a plurality of conveying drive shafts 52, the surface of the conveying drive shaft 52 is connected with the conveying belt 51, and the end of at least one conveying drive shaft 52 is connected with the driving motor 53.

[0038] When the material on the surface of the material supporting block 63 needs to be conveyed to the next process, the second cylinder 72 drives the material pushing plate 73 to move to the left side, so that the material on the surface of each material supporting block 63 is pushed to the surface of the conveying belt 51. Then the driving motor 53 drives the conveying drive shaft 52 to rotate, so that the conveying belt 51 produces reciprocating motion when the conveying drive shaft 52 rotates.

[0039] The working principle and use method of the utility model:

[0040] The film is pulled by external traction equipment, and covers the material to be vacuum packaged on the surface of the support frame 1. In the process of continuously pulling the film, the surface of the film placing shaft 22 rotates to realize continuous feeding. When the material moves above the material supporting block 63, the film first stops moving. Then the piston rod of the hydraulic oil cylinder 46 pushes the lifting driving shaft 45 to generate an upward driving force, at this time the middle part of the first lifting support plate 42 and the second lifting support plate 43 is hinged to rotate, and the two ends of the first lifting support plate 42 and the second lifting support plate 43 also rotate relative to the lifting base 41 and the lifting top cover 44 respectively. Gradually, the included angle between the first lifting support plate 42 and the second lifting support plate 43 changes, and then the height of the lifting top cover 44 changes.

[0041] The change of the height of the lifting top cover 44 will simultaneously change the height of the shearing support frame 31, until the rectangular knife plate 32 can cut the film upward. In the process of being cut, the first cylinder 61 also appropriately moves the material supporting block 63 upward, so that the rectangular knife plate 32 can complete the cutting operation. The surface of the material after being cut is still attached to the vacuum film, and falls on the surface of the material supporting block 63 in the middle of the rectangular knife plate 32.

[0042] After the height of the lifting top cover 44 falls back, the second cylinder 72 drives the material pushing plate 73 to move to the left side, so that the material on the surface of each material supporting block 63 is pushed to the surface of the conveying belt 51. Then the driving motor 53 drives the conveying driving shaft 52 to rotate, and the conveying driving shaft 52 rotates to make the conveying belt 51 reciprocate, so as to convey the final material to the outside.

[0043] The specific embodiments described in the present application are only illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
