[0002] A film tearing machine, also known as a demoulding machine, a film stripping machine or a film stripping machine, is a device used to remove film or packaging materials from products. It is usually used in plastic packaging, food packaging, the electronics industry and other fields to improve production efficiency and reduce labor intensity. When the film tearing machine is tearing the polarizer on the liquid crystal glass, it is usually necessary to tear off one corner of the liquid crystal glass to provide a starting point, so as to better control the entire film tearing process and ensure that the polarizer can be peeled off smoothly and completely. However, during the film tearing process, the liquid crystal glass is always at a 45-degree angle for transporting the film, which occupies a relatively large area of ​​the table.

One end of the No. 1 rotating shaft 6 and the No. 2 rotating shaft 7 extends out of the tearing machine side plate 1 near the motor 3 and is respectively sleeved with a driving gear 4 and a driven gear 5. The driving gear 4 and the driven gear 5 are meshed with each other, and then the motor 3 is started to make The output shaft on the motor 3 drives the driving gear 4 to rotate, and the driving gear 4 drives the biting glue stick 9 on the No. 1 rotating shaft 6 to start rotating. The driven gear 5 meshes with the driving gear 4 and drives the biting gear 8 on the No. 2 rotating shaft 7 to rotate when the driving gear 4 rotates. At this time, the biting gear 8 and the biting glue stick 9 rotate relatively to first mesh with the torn corner of the liquid crystal glass, and the film on the liquid crystal glass is torn off through the continuous rotation of the biting gear 8 and the biting glue stick 9 and the rotation and transportation of multiple sets of transport rollers 20.

[0026] A limit plate 11 is fixedly provided on one side corresponding to the top of the film tearing machine stand 2, and the end of the limit plate 11 is fixedly connected to the side of the positioning plate 10, and one side of the limit plate 11 is in contact with the side of one group of film tearing machine side plates 1. The limit plate 11 prevents the liquid crystal glass from sliding out of the film tearing machine stand 2 during the angle adjustment process.

[0027] A slot 13 is provided on the positioning plate 10, and the slot 13 runs through both sides of the positioning plate 10. A slot 14 is provided on the top of the slot 13. When tearing the film of the liquid crystal glass, the liquid crystal glass is transported forward at an angle of 45 degrees, and this needs to be adjusted. At this time, the cylinder 15 is started, so that the piston rod on the cylinder 15 pushes the sliding plate 17 connected to the baffle 16 to slide in the slot 13.

[0028] The adjustment assembly includes a baffle 16, a slide plate 17, a connecting rod 18 and an adjustment plate 12. The baffle 16 is fixedly connected to the end of the piston rod on the cylinder 15. A slide plate 17 is fixedly connected to the corresponding empty groove 13 on one side of the baffle 16. The slide plate 17 is slidably connected in the empty groove 13. The top of the slide plate 17 is slidably engaged in the slot 14.

When pushing the liquid crystal glass, the adjustment bar 19 makes the other side of the liquid crystal glass press against one side of the limit plate 11, so that the liquid crystal glass gradually moves ninety degrees toward the side of the transport roller 20, thereby saving the table width of the equipment.

[0031] Working principle: When using this device, first tear off a corner of the liquid crystal glass that needs to be torn off to provide a starting point, so as to better control the entire film tearing process and ensure that the polarizer can be peeled off smoothly and completely, and then place the side of the liquid crystal glass that needs to be torn off on the top of the tearing machine stand 2, and place a corner of the liquid crystal glass on the innermost set of transport rollers 20, and transport the liquid crystal glass to one side by the rotation of the transport rollers 20, and then start the motor 3, so that the output shaft on the motor 3 drives the driving gear 4 to rotate, and the driving gear 4 drives the biting rubber stick 9 on the first rotating shaft 6 to start rotating, and the driven gear 5 drives the biting gear 8 on the second rotating shaft 7 to rotate by meshing with the driving gear 4 when the driving gear 4 rotates. At this time, the biting gear 8 and the biting rubber stick 9 rotate relatively to first mesh with the torn corner of the liquid crystal glass , through the continuous rotation of the biting gear 8 and the biting rubber stick 9 and the rotation and transportation of multiple groups of transport rollers 20, the film on the liquid crystal glass is torn off. When the film of the liquid crystal glass is torn off, the liquid crystal glass is transported forward at a forty-five degree angle, which needs to be adjusted. At this time, the cylinder 15 is started, so that the piston rod on the cylinder 15 pushes the slide plate 17 connected to the baffle 16 to slide in the empty groove 13. When the top of the slide plate 17 slides in the card groove 14, the slide plate 17 is prevented from shaking. The connecting rod 18 drives the adjustment plate 12 to slide on the top of the tearing machine stand 2 through the sliding of the slide plate 17, and the adjustment bar 19 at the bottom of the adjustment plate 12 pushes one side of the liquid crystal glass when sliding. In the process of pushing the liquid crystal glass, the adjustment bar 19 makes the other side of the liquid crystal glass against one side of the limit plate 11, so that the liquid crystal glass gradually moves toward one side of the transport roller 20 at ninety degrees, so as to save the table width of the equipment.
