[0002] Protective films can be divided into digital product protective films, car protective films, household protective films, food preservation protective films, etc. according to their uses. With the popularity of digital products such as mobile phones in China, protective films have gradually become a general term for screen protective films. During the composite processing of protective films, bubbles can easily affect the appearance and quality of the protective film products.

[0003] In the prior art, a Chinese patent with a reference number of CN 217373546 U discloses a protective film bubble removal device, including an equipment body located on the ground, with adjustment components installed on both sides of the middle of the equipment body, respectively, and the adjustment components include adjustment plates, and the middle of two groups of adjustment plates are connected to a first extrusion shaft. The utility model can adjust the distance between the first extrusion shaft and the second extrusion shaft according to protective films of different thickness specifications through the adjustment component installed in the middle of the processing table. At the same time, the extrusion force of the first extrusion shaft on the second extrusion shaft can also be adjusted according to the requirements of the composite processing of the protective film, thereby improving the practicality of the bubble removal device in the composite processing of the protective film.

[0023] It should be noted that, since the existing protective film bubble removal device extrude the protective film through two extrusion shafts, and since the protective film is processed, conveyed and wound in the form of long strips, the bubbles on the protective film gather to form large bubbles after continuous extrusion. The large bubbles will cause the protective film to be locally compressed and deformed, and then the protective film will be wrinkled. In this embodiment, the protective film on the bubble squeezing table 3 is pressed on the horizontal transverse conveying path by the bubble squeezing component 6, and the protective film is horizontally and longitudinally rolled and squeezed by the roller 69, so that the bubbles on the protective film can be pushed and discharged from one side of the protective film, thereby reducing the amount of bubble aggregation, thereby avoiding the problem of expansion, deformation and damage of the protective film caused by the generation of large bubbles.

[0024] Specifically, in the present embodiment, the present scheme mainly comprises a bubble squeezing station 3 and a bubble squeezing assembly 6. When in use, the protective film is horizontally conveyed to the top of the bubble squeezing station 3. When the defoaming operation is performed, the conveying of the protective film is stopped, and the first hydraulic cylinders 62 on the two support plates 61 work synchronously. The first hydraulic cylinder 62 drives the pressing plate 63 to move downward through the output end on one side thereof.
