Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Embodiment 1: Refer to Figures 1-4 , a stretch film vacuum packaging machine for easily torn packaging, including a frame 1, a first unwinding mechanism 2 is connected to the frame 1, a film pressing mechanism 3 is fixedly connected to the frame 1, a hot pressing mechanism 4 for sealing the packaging film is connected to the frame 1, a second unwinding mechanism 5 is connected to the frame 1, and the second unwinding mechanism 5 is located between the film pressing mechanism 3 and the hot pressing mechanism 4;

[0022] The film pressing mechanism 3 includes a housing 31, the housing 31 is fixedly connected to the frame 1, a first electric telescopic rod 32 is fixedly connected to the upper end of the housing 31, the telescopic end of the first electric telescopic rod 32 extends into the housing 31 and is fixedly connected to a first fixing seat 33. The first fixing seat 33 is a heat-insulating seat. A first mold 34 is fixedly connected to the first fixing seat 33. A heater 35 is connected to the first mold 34. A plurality of model blocks 36 are connected to the bottom end of the first mold 34. Convex balls 37 are connected to the corner positions of each model block 36 on the first mold 34. The first mold 34, the model block 36 and the convex ball 37 are of an integral structure.

[0023] Working process:

[0024] The first unwinding mechanism 2 releases the bottom film of the stretch film. The bottom film of the stretch film sequentially passes through the housing 31 and the hot pressing mechanism 4. After the heater 35 is started, it heats up the first mold 34. After the first mold 34 is heated up, it conducts heat to the model block 36 and the convex ball 37, heating up the convex ball 37. After the first electric telescopic rod 32 is energized and started, it drives the first fixed seat 33 to move downward by a set distance. The first fixed seat 33 drives the model block 36 and the convex ball 37 to move downward by a set distance through the first mold 34. One end of the bottom film of the stretch film is fixed by the hot pressing mechanism 4, and the other end of the bottom film of the stretch film is fixed by the first unwinding mechanism 2. The model block 36 and the convex ball 37 move downward by a set distance and contact the bottom film of the stretch film. The model block 36 hot presses a material storage groove on the bottom film of the stretch film, and the convex ball 37 hot presses an arc groove on the bottom film of the stretch film;

[0025] The donkey-hide gelatin cake is placed in the material storage groove. After the stretch film bottom film with the donkey-hide gelatin cake passes through the hot pressing mechanism 4, the second unwinding mechanism 5 releases the stretch film top film. The stretch film top film passes through the hot pressing mechanism 4, and the hot pressing mechanism 4 hot presses the stretch film top film onto the stretch film bottom film. After the stretch film top film and the stretch film bottom film are combined, the donkey-hide gelatin cake in the material storage groove is sealed and packaged. At the same time, a bubble is formed between the stretch film top film and the arc groove. It is cut into pieces by the cake cutting device. Each piece of donkey-hide gelatin cake packaging has a bubble. When opening the packaging of the donkey-hide gelatin cake, squeeze the bubble out forcefully. After the bubble is squeezed out, the bottom film and the top film naturally separate. Hold both sides of the film with both hands and gently tear it, which is convenient for opening the packaging of the donkey-hide gelatin cake.

[0026] Embodiment 2: In Embodiment 1, when the bottom film of the telescopic film is hot pressed by the model block 36 and the convex ball 37, the bottom film of the telescopic film is depressed downward to a certain extent after being pressed, thereby reducing the hot pressing effect of the model block 36 and the convex ball 37 on the bottom film of the telescopic film. Refer to Figure 3, as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that a support mechanism 6 for improving the film pressing effect is connected to the bottom end of the housing 31. The support mechanism 6 includes a second electric telescopic rod 61, the second electric telescopic rod 61 is fixedly connected to the bottom end of the housing 31, the telescopic end of the second electric telescopic rod 61 extends into the housing 31 and is fixedly connected with a second fixed seat 62, a second mold 63 is fixedly connected to the second fixed seat 62, several first grooves 64 matching with the model blocks 36 are opened at the upper end of the second mold 63, several arc grooves 65 matching with the convex balls 37 are opened at the upper end of the second mold 63. When the first fixed seat 33 drives the model blocks 36 and the convex balls 37 to move downward through the first mold 34, the second electric telescopic rod 61 drives the second fixed seat 62 to move upward, the second fixed seat 62 drives the second mold 63 to move, and after the second mold 63 moves, it supports the bottom film of the stretch film. The bottom film of the stretch film will not sink downward after being pressed. The first grooves 64 cooperate with the model blocks 36, and the arc grooves 65 cooperate with the convex balls 37, so as to improve the hot pressing effect on the bottom film of the stretch film.

[0027] Embodiment 3: In Embodiment 1, the first electric telescopic rod 32 drives the first fixed seat 33 to move downward by a set distance, the first fixed seat 33 drives the model blocks 36 and the convex balls 37 to move downward by a set distance through the first mold 34, the side edge of the bottom end of the first mold 34 contacts the side edge of the upper end of the second mold 63, and the side edge of the bottom film of the stretch film is hot pressed, resulting in the side edge of the bottom film of the stretch film being hot pressed and deformed. Refer to Figure 4 , as another preferred embodiment of the present utility model, the difference from Embodiment 2 is that an isolation mechanism 7 is connected to the bottom end of the first mold 34. The isolation mechanism 7 includes an isolation ring 72. A second groove 71 is opened at the bottom end of the first mold 34, the isolation ring 72 is connected to the second groove 71, the bottom end of the isolation ring 72 extends out of the second groove 71, the isolation ring 72 is a heat-insulating rubber ring. The first fixed seat 33 drives the model blocks 36 and the convex balls 37 to move downward by a set distance through the first mold 34. The isolation ring 72 is located between the first mold 34 and the second mold 63 to prevent the first mold 34 from hot pressing the side edge of the bottom film of the stretch film.
