[0033] The clamping plate 4 is located on the left side of the housing 1, and an inclined guide plate 14 is fixedly connected to its bottom. The guide plate 14 is inclined towards the housing 1 and is used to guide the gas so that the gas can blow the lower part of the housing 1.

[0034] Pull plate 5 is installed on the left side of clamping plate 4;

[0035] The guide mechanism consists of two sets, which are installed on the clamping plate 4 and the fixing plate 3. The housing 1 is fitted onto the guide mechanism, and the guide mechanism provides lateral guidance for the clamping plate 4.

[0036] The guiding mechanism includes guide posts 6, which are fixedly mounted on the right side of clamping plate 4. The right side of clamping plate 4 has two mounting holes, the inner walls of which are fixedly connected to the outer sides of the corresponding guide posts 6. Pull plate 5 is fixedly sleeved on the two guide posts 6. The pull plate 5 has two fixing holes on one side for fixing the guide posts 6. A slider 7 is slidably mounted on the guide post 6. The slider 7 is welded and fixed to the bottom of fixing plate 3. The guide post 6 and slider 7 cooperate to provide a lateral guiding effect for clamping plate 4. Two first through holes are opened on the inner wall of the front side of housing 1. The inner walls of the first through holes are in movable contact with the outer sides of the corresponding guide posts 6. The first through holes are used for the corresponding guide posts 6 to pass through.

[0037] Cylinder 2 is installed at the bottom of fixed plate 3, and its output shaft is fixedly installed on the right side of pull plate 5. Clamping plate 4 is sleeved on the output shaft of cylinder 2. A second connecting ring 12 is fixedly connected to the bottom of fixed plate 3. A second through hole is opened at the top of housing 1. The right side of the second through hole is open. The second connecting ring 12 is located in the second through hole. The second through hole is used for the second connecting ring 12 to pass through. An external threaded sleeve 11 is fixedly sleeved on the outside of cylinder 2. The external threaded sleeve 11 is threaded in the second connecting ring 12. The external threaded sleeve 11 has a second external thread on the outside and a second internal thread on the inside of the second connecting ring 12. The second external thread and the second internal thread are threadedly connected. Cylinder 2 is fixedly connected to fixed plate 3 through external threaded sleeve 11 and second connecting ring 12.

Its control principle is existing technology and will not be described in detail here.

[0038] This embodiment, through a series of structural settings, can achieve fully automatic film tearing by automatic drive combined with airflow assistance, achieving the effect of manual film tearing, thereby improving the working efficiency and automation of the equipment and reducing the intensity of manual labor.

[0039] The usage method of this embodiment is as follows: According to product requirements, the position of the film-tearing structure 500, the stroke of the cylinder 2, and the stroke of the lifting structure 400 are preset via the PLC touchscreen. The motion module 200 is controlled via the PLC touchscreen control panel, allowing adjustment of the position of the film-tearing structure 500. After the film-tearing structure 500 is moved to the preset position, the pressing structure 300 is activated via the PLC touchscreen control panel. The pressing structure 300 applies pressure to the product, preventing it from shifting. Then, the lifting structure 400 is activated via the PLC touchscreen control panel, driving the film-tearing structure 500 to move downwards, causing the anti-slip silicone at the bottom of the housing 1 to press against the film on the product. When in position, a signal is given to the external solenoid valve, which supplies air into the housing 1. The air is blown onto the clamping plate 4 through multiple air outlets 8. The air is guided to the film via the guide plate 14, forming an air vortex that slightly lifts one side of the film. At this time, the cylinder 2 is activated, and its output end pulls the clamping plate 4 to adhere to the film via the pull plate 5. On the left side of the housing 1, as the clamping plate 4 moves to the right, it clamps the side of the film that has been lifted. At the same time, the clamping plate 4 blocks multiple air outlets 8, stopping the blowing. After the cylinder 2 is in position, the PLC touch control screen controls the lifting structure 400 to start and drive the film-tearing structure 500 to rise to its position. The motion module 200 then drives the film-tearing structure 500, which is holding the film, to move to the right. While the film-tearing structure 500 is moving to the right, the film-tearing operation can be performed, allowing the film to be completely torn off the product. Finally, the pressing structure 300 and the cylinder 2 are reset, and the pressing structure 300 releases the pressure on the product. At the same time, the output shaft of the cylinder 2 drives the pull plate 5 and the clamping plate 4 to move back to the left to release the clamping of the film, thus removing the film and completing the film-tearing action. By using the cylinder-driven clamping principle, supplemented by airflow, and in conjunction with the motion module 200, the effect of manual film tearing can be achieved. With the settings of the PLC touch control screen, the effect of fully automatic film tearing can be achieved, thereby improving the working efficiency and automation of the equipment and reducing the intensity of manual labor.
