[0057] Furthermore, the lifting member 42 further includes a pressing portion 421 and a mounting portion 424. The pressing portion 421 is connected to the lifting portion 422 via the mounting portion 424, and the mounting portion 424 is hinged on the quick-access seat 41. Pressing the pressing portion 421 downward causes the lifting portion 422 to tilt upward, driving the product to be laminated to tilt upward, so that the product to be laminated is partially released from the mold cavity 31, so as to take out the product to be laminated.

[0058] Furthermore, a guide cavity 4121 is formed on the cache seat 41 , and the lifting member 42 includes a guide column 423 . The guide cavity 4121 extends in a vertical direction. The guide column 423 is disposed on the mounting portion 424 , and the guide column 423 is slidably disposed in the guide cavity 4121 .

[0059] Furthermore, the cache seat 41 includes a seat body 411 and a limiting portion 412 . The limiting portion 412 is protruded on the seat body 411 toward the positioning mold 3 . A pressing cavity 4111 is opened on the seat body 411 . The pressing portion 421 is movably set in the pressing cavity 4111 . The guide cavity 4121 is opened on the limiting portion 412 .

[0060] In order to maintain the balance of the lifting piece 42, there are two limiting parts 412, and the two limiting parts 412 are arranged at intervals along the width direction of the product to be filmed. A guide cavity 4121 is opened on each limiting part 412, and guide columns 423 are arranged on the opposite sides of the installation part 424.

[0061] Specifically, the mounting portion 424 extends from the pressing cavity 4111 to between the two limiting portions 412 , and one end of the limiting portion 412 away from the seat body 411 abuts against the tilting portion 422 .

[0062] Furthermore, a limiting arc surface 4123 is provided on one end of the limiting portion 412 away from the seat body 411 , and the contour of the limiting arc surface 4123 is matched with the contour of the tilting portion 422 to play a good supporting role.

[0063] Specifically, the guide cavity 4121 is arranged upward and does not penetrate to the bottom of the limiting portion 412, so as to ensure that the lifting member 42 is installed on the quick-access seat 41. Before film application, the upper surface of the lifting portion 422 and the upper surface of the limiting portion 412 are on the same horizontal plane to prevent interference with film application and prevent bubbles from appearing between the protective film and the product to be applied.

[0064] Furthermore, the seat body 411 and the limiting portion 412 are both fixedly installed in the fixing cavity 12 .

[0065] Specifically, a first fixing column 4112 is disposed on the seat body 411 , a first fixing hole 13 is opened in the fixing cavity 12 , and the first fixing column 4112 and the first fixing hole 13 can be connected by a fastener.

[0066] Specifically, a second fixing post 4122 is provided on the limiting part 412, and a second fixing hole 14 is formed in the fixing cavity 12. The second fixing post 4122 and the second fixing hole 14 can be connected by fasteners.

[0067] Furthermore, the numbers of the first fixing post 4112, the first fixing hole 13, the second fixing post 4122, and the second fixing hole 14 are not limited and can be adjusted according to actual situations, as long as the first fixing post 4112 and the first fixing hole 13 are correspondingly connected, and the second fixing post 4122 and the second fixing hole 14 are correspondingly connected.

[0068] Furthermore, the quick access component 4 further includes an elastic member 43. One end of the elastic member 43 is connected to the cavity wall of the pressing cavity 4111, and the other end is connected to the pressing part 421. The arrangement of the elastic member 43 enables the pressing part 421 to automatically reset.

[0069] Specifically, the elastic member 43 can be a spring, but of course it is not limited thereto, as long as it can enable the pressing part 421 to automatically reset.

[0070] Furthermore, friction stripes 425 are provided on the pressing part 421. The arrangement of the friction stripes 425 can increase the friction between the operator and the pressing part 421, preventing poor pressing effect due to smoothness.

[0071] Furthermore, the quick access component 4 further includes an elastic pad 44. The elastic pad 44 is attached to the tilting part 422 and is in contact connection with the bottom surface of the product to be film - pasted. The arrangement of the elastic pad 44 can play a certain protective role for the product to be film - pasted.

[0072] As Figure 8 shown, a socket 33 is formed in the positioning die 3. The socket 33 communicates with the tilting cavity 32. The tilting part 422 passes through the socket 33 and extends into the tilting cavity 32.

[0073] Furthermore, an avoidance cavity 34 is formed in the positioning die 3. The avoidance cavity 34 is used to avoid the structures on the product to be film - pasted, such as avoiding the lens of the product to be film - pasted.

[0074] Furthermore, the positioning die 3 includes a die body and a limiting block 35. Along the length direction of the product to be film - pasted, the limiting block 35 is arranged at one end of the die body close to the quick access component 4. The limiting block 35 can block the movement of the film - pasting roller 21. The arrangement of the limiting block 35 makes the movement track of the film - pasting roller 21 exactly between the two edges in the length direction of the product to be film - pasted, preventing the film - pasting roller 21 from moving too far away from the product to be film - pasted, and further preventing bubbles from being generated between the protective film and the product to be film - pasted when the film - pasting roller 21 approaches the product to be film - pasted again, ensuring the film - pasting effect.

[0075] In order to ensure the stability of the contact between the film laminating roller 21 and the limiting blocks 35 , limiting blocks 35 are provided on opposite sides of the film laminating roller 21 along the width direction of the product to be laminarized.

[0076] Specifically, the mold cavity 31 , the warping cavity 32 , the insertion port 33 and the avoidance cavity 34 are all opened on the mold body.

[0077] like Figures 1 - 3 , Figure 9 As shown, the film sticking assembly 2 further includes a sliding assembly 23, which includes a pulley 231, a ball bearing 233 and the above-mentioned sliding seat 232. The pulley 231 is rotatably arranged on the sliding seat 232, and the pulley 231 and the ball bearing 233 are both in rolling contact with the base 1. Such an arrangement can make the film sticking effect better, reduce friction and wear, and save more effort when sliding.

[0078] In some preferred embodiments, the pulley 231 may also be a bearing, and the friction between the bearing and the base is reduced by the rolling of the bearing, making sliding more labor-saving.

The arrangement of the slide groove 11 can prevent the pulley 231 from sliding out of the base 1, and make the laminating roller 21 just abut against the edge of the product to be laminated, so as to prevent the laminating roller 21 from abutting against the protective film back and forth and causing bubbles.

[0081] Specifically, the pulley 231 is in rolling contact with the upper and lower groove walls of the slide groove 11 , and the ball 233 is connected to the groove surface of the slide groove 11 connecting the upper and lower groove walls.

[0082] Further, at least one pulley 231 may be provided on the base 1. Specifically, in this embodiment, two pulleys 231 are provided on the base 1.

[0083] Furthermore, along the width direction of the product to be film-coated, sliding components 23 are respectively provided on two opposite sides of the film-coating roller 21 , and sliding grooves 11 are also provided on two opposite sides of the base 1 to accommodate the rolling of the pulley 231 .
