DETAILED DESCRIPTION

[0021] In order to make the technical personnel in the art better understand the technical scheme of the utility model, the utility model will be further described in detail below with the drawings.

[0022] Please refer to Figures 1-6 The utility model embodiment provides a kind of technical scheme of the film pressing device of the full-automatic sand bomb packaging machine, including rack 1 and transmission assembly, first fixed block 4 and second fixed block 6 are horizontally arranged in rack 1, first fixed block 4 is located above second fixed block 6, hot pressing plate 3 and cutting knife 7 are horizontally slidably connected in rack 1, hot pressing plate 3 and cutting knife 7 are respectively with first fixed block 4 and second fixed block 6 abutment cooperation, and hot pressing plate 3 is parallel with cutting knife 7 and staggered, when hot pressing plate 3 moves towards first fixed block 4, cutting knife 7 is horizontally moved away from second fixed block 6 by transmission assembly, specifically, one blanking hole 2 is set in rack 1, and packaging film after hot pressing and cutting will pass through blanking hole 2, and first fixed block 4 and second fixed block 6 are arranged on the inner wall of blanking hole 2.

[0023] In this embodiment, the transmission assembly includes a gear 13, a first rack 12 meshing with the gear 13, and a second rack 14 meshing with the gear 13. A slider 9 is provided between the first rack 12 and the hot press plate 3. The gear 13 is rotatably connected within the frame 1. A limiting plate 17 is provided at the bottom of the second rack 14. A connecting rod 15 is provided between the limiting plate 17 and the cutting blade 7. Specifically, the frame 1 is provided with a film conveying mechanism for conveying packaging film. When the hot press plate 3 drives the first rack 12 to perform hot pressing via the slider 9, the transmission assembly is connected via the gear 13. The meshing transmission of 13 can drive the second rack 14 to slide horizontally in the opposite direction. Through the limiting plate 17 and the connecting rod 15, it drives the lower cutting blade 7 to move in the opposite direction. When the hot pressing is completed, during the reverse movement of the hot pressing plate 3, the film conveying mechanism conveys the packaging film a certain distance and stops, so that the section of packaging film that has been hot pressed is facing the cutting blade 7. The cutting blade 7 moves toward the second fixed block 6 to cut this section of packaging film, completely separating the hot pressing and cutting, and fully hot pressing, which can avoid the impact and vibration of the cutting blade 7 from affecting the quality of hot pressing.

[0024] In this embodiment, a horizontal groove 11 is formed inside the frame 1, and the slider 9 is slidably connected in the groove 11. A driving component for driving the slider 9 to slide horizontally is provided in the groove 11. The driving component includes a screw 10, which is rotatably connected in the groove 11. The slider 9 is screwed to the screw 10. Specifically, a motor is provided on one side of the frame 1. The output end of the motor is coaxially fixedly connected to one end of the screw 10. The motor drives the screw 10 to rotate. The size of the groove 11 is adapted to the slider 9. The groove 11 restricts the axial rotation of the slider 9. The slider 9 is driven to move horizontally along the length direction of the groove 11 through the helical transmission of the screw 10, thereby driving the first rack 12 and the hot press plate 3 to move horizontally. More specifically, a controller is provided on the frame 1. The controller is connected to the motor signal. It should be noted that the specific model and specifications of the motor and controller need to be selected and determined according to the actual specifications of the device. The specific power supply and its principle are clear to those skilled in the art, so they will not be described in detail.

[0025] In this embodiment, a clamping block 5 is horizontally slidably connected inside the frame 1. The connecting rod 15 and the cutting blade 7 are both horizontally slidably connected inside the clamping block 5. A spring 16 is sleeved on the connecting rod 15. The two ends of the spring 16 are fixedly connected to the limiting plate 17 and the clamping block 5, respectively. Specifically, when the second rack 14 drives the limiting plate 17 to move horizontally toward the second fixing block 6, the clamping block 5 is first moved by the spring 16 to fix a section of packaging film that has been heat-sealed, so as to prevent the packaging film from shaking during the cutting process and affecting the cutting effect. Then the limiting plate 17 continues to move, compressing the spring 16, and the cutting blade 7 is moved by the connecting rod 15. The cutting blade 7 extends out from the clamping block 5 to cut the section of packaging film that has been heat-sealed.

[0026] In this embodiment, a cutting groove 8 is provided in the second fixing block 6, and the cutting blade 7 is inserted into the cutting groove 8. Specifically, the cutting groove 8 is provided to prevent the cutting blade 7 from rigidly colliding with the second fixing block 6, so as to avoid damaging the cutting head of the cutting blade 7.

[0027] Working principle: The film pressing device of this fully automatic sand cannon packaging machine starts the motor, which drives the screw 10 to rotate. The slider 9 drives the first rack 12 and the hot pressing plate 3 to move horizontally. When the hot pressing plate 3 drives the first rack 12 to perform hot pressing through the slider 9, the second rack 14 can be driven to slide horizontally in the opposite direction through the meshing transmission of the gear 13. Through the limit plate 17 and the connecting rod 15, the cutting blade 7 below moves in the opposite direction. When the hot pressing is completed, during the reverse movement of the hot pressing plate 3, the film conveying mechanism can be controlled by the controller to convey the packaging film a certain distance and stop, so that the section of packaging film that has been hot-pressed is... When the second rack 14 drives the limiting plate 17 to move horizontally toward the second fixing block 6, the clamping block 5 is first moved by the spring 16 to fix the already heat-sealed section of packaging film, so as to prevent the packaging film from shaking during the cutting process and affecting the cutting effect. Then the limiting plate 17 continues to move, compressing the spring 16, and drives the cutting blade 7 to move through the connecting rod 15. The cutting blade 7 extends out from the clamping block 5 to cut the already heat-sealed section of packaging film, completely separating the heat pressing and cutting, and fully heat pressing, so as to avoid the impact and vibration of the cutting blade 7 from affecting the quality of heat pressing.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
