[0030] The technical solution of the present utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0031] See Figures 1 to 3 As shown, the embodiment of the present application provides a printing paper laminating machine, including:

[0032] Rack 100;

[0033] The printing paper unwinding mechanism 2 is provided at one end of the frame 100 and has printing paper 200 rolled thereon;

[0034] The printing paper rewinding mechanism 3 is provided at the other end of the frame 100;

[0035] The tensioning roller mechanism 4 is provided on the frame 100 and is located between the printing paper unwinding mechanism 2 and the printing paper rewinding mechanism 3;

[0036] The printing paper 200 on the printing paper unwinding mechanism 2 is pulled out and passes through the tensioning roller mechanism 4 to be connected to the printing paper rewinding mechanism 3;

[0037] The heating roller 5 is rotatably mounted on the frame 100 and close to the printing paper unwinding mechanism 2. The printing paper 200 pulled out by the printing paper unwinding mechanism 2 covers the heating roller 5.

[0038] The film unwinding mechanism 6 is provided on the frame 100 and is located on one side of the printing paper unwinding mechanism 2, and has a film 600 wound thereon;

[0039] The film winding mechanism 7 is provided on the frame 100 and is located above the heating roller 5. The film 600 on the film unwinding mechanism 6 is pulled out and connected to the film winding mechanism 7.

[0040] The film winding mechanism 7 drives the film 600 to move toward the heating roller 5 , so as to adhere the film 600 to the printing paper 200 and press the printing paper 200 onto the heating roller 5 .

[0041] By replacing the lower roller with the heating roller 5 and replacing the traditional fixed upper roller with the movable film winding mechanism 7, during lamination, the film winding mechanism 7 is started, driving the film 600 to move toward the heating roller 5, so as to adhere the film 600 to the printing paper 200 and press the printing paper 200 against the heating roller 5, thereby completing the lamination through the cooperation of the film winding mechanism 7 and the heating roller 5, so that printing paper of any thickness can be processed without manual adjustment, which is practical and convenient, and greatly improves the processing efficiency.

[0042] Furthermore, the film unwinding mechanism 6 includes a film winding frame 61 provided on the frame 100 , and a film unwinding roller 62 rotatably provided on the film winding frame 61 , and the film 600 is wound and stored on the film unwinding roller 62 .

[0043] The film winding mechanism 7 includes a film winding seat 71 arranged below the film winding rack 61, and a film winding roller 72 rotatably arranged on the film winding seat 71. The film 600 on the film winding roller 62 is pulled out and connected to the film winding roller 72. A coating drive component 73 is also provided between the film winding seat 71 and the film winding rack 61, which can drive the film winding seat 71 to move toward the heating roller 5.

[0044] Before lamination, the film 600 to be processed is rolled up and stored on the film unwinding roller 62, and then one end of the film 600 is pulled out and connected to the film winding roller 72. During lamination, the lamination drive assembly 73 is started, driving the film winding seat 71 to move toward the heating roller 5, thereby driving the film winding roller 72 and the film 600 to move synchronously, so as to adhere the film 600 to the printing paper 200 and press the printing paper 200 onto the heating roller 5 to complete the lamination.

[0045] The heating roller 5 design can heat the printing paper 200 and the film 600 while the film winding roller 72 and the heating roller 5 cooperate to squeeze the film tightly against the outer wall of the printing paper, further improving the efficiency of the lamination, which is practical and convenient.

[0046] In this embodiment, the heating processing principle of the heating roller 5 is a commonly used existing technology in this field and will not be described in detail here.

[0047] In this embodiment, the laminating drive assembly 73 is a telescopic cylinder.

[0048] Furthermore, a film limiting mechanism 8 is provided on the film winding seat 71 .

[0049] Specifically, the film limiting mechanism 8 includes a limiting seat 81 provided on the film winding seat 71, a telescopic rod group 82 provided on the limiting seat 81, a limiting roller group 83 connected on both sides of the limiting seat 81, and a connecting member 84 hinged between the limiting roller group 83 and the output end of the telescopic rod group 82. Elastic members 85 are respectively connected between the two limiting roller groups 83 and the limiting seat 81.

[0050] During operation, the limiting roller set 83 is respectively attached to both sides of the film 600 to ensure that the film 600 is always attached to and rolled up on the film winding roller 72 .

[0051] When the width of the printing paper 200 changes, the width of the film 600 also changes accordingly, and therefore the distance between the limiting rollers 83 needs to be adjusted accordingly. When adjustment is needed, the telescopic rod assembly 82 is activated, driving one end of the connecting member 84 toward or away from the limiting seat 81. Since the length of the connecting member 84 is fixed, when one end approaches or moves away from the limiting seat 81, the other end, constrained by the elastic member 85, also moves toward or away from the limiting seat 81, thereby driving the limiting rollers 83 toward or away from the limiting seat 81 to adjust the distance between the two limiting rollers 83. This is practical and convenient, ensuring that the limiting rollers 83 can be attached to both sides of the film 600, ensuring that the film 600 is always attached and wound around the film winding roller 72.

[0052] In this embodiment, the elastic member 85 is a spring.

[0053] Furthermore, the tensioning roller mechanism 4 includes a first tensioning roller 41 and a second tensioning roller 42 which are respectively rotatably arranged on the frame 100. The first tensioning roller 41 is arranged on the side of the heating roller 5 away from the printing paper unwinding mechanism 2, and the second tensioning roller 42 is arranged on the side obliquely above the printing paper winding mechanism 3. The printing paper 200 on the printing paper unwinding mechanism 2 is pulled out and passes through the first tensioning roller 41 and the second tensioning roller 42 in sequence and is connected to the printing paper winding mechanism 3.

[0054] By cooperating with the first tensioning roller 41 and the second tensioning roller 42 , the printing paper 200 is kept flat during the laminating process, thereby ensuring smooth laminating.

[0055] Furthermore, the printing paper winding mechanism 3 includes a printing paper winding seat 31 fixed on the frame 100, and a printing paper winding roller 32 rotatably arranged on the printing paper winding seat 31. The printing paper 200 on the printing paper unwinding mechanism 2 is pulled out and passes through the first tensioning roller 41 and the second tensioning roller 42 in sequence and is connected to the printing paper winding roller 32.

[0056] Furthermore, the frame 100 is provided with a winding drive mechanism 9 that can synchronously drive the printing paper winding roller 32 and the second tensioning roller 42 to rotate.

[0057] Specifically, the winding drive mechanism 9 includes a winding drive motor 91 provided on the frame 100, a driving gear 92 provided on the end of the second tensioning roller 42 close to the winding drive motor 91, a driven gear 93 provided on the end of the printing paper winding roller 32 close to the winding drive motor 91, a transmission gear group 94 provided on the frame 100 and meshing with the driving gear 92 and the driven gear 93 respectively, and a transmission belt assembly 95 provided between the second tensioning roller 42 and the winding drive motor 91.

[0058] During operation, the winding drive motor 91 is started, and then the second tensioning roller 42 and the driving gear 92 are driven to rotate through the transmission belt assembly 95, thereby driving the transmission gear group 94 to rotate, and then synchronously driving the driven gear 93 and the printing paper winding roller 32 to rotate to wind the printing paper 200. It is practical and convenient. The synchronous rotation of the second tensioning roller 42 and the printing paper winding roller 32 makes the winding movement process of the printing paper 200 smoother.

[0059] Furthermore, the printing paper unwinding mechanism 2 includes a printing paper unwinding seat 21 fixed on the frame 100, a printing paper unwinding roller 22 rotatably arranged on the printing paper unwinding seat 21, and an unwinding drive assembly 23 arranged on the frame 100 and capable of driving the printing paper unwinding roller 22 to rotate.

[0060] Through the coordinated operation of the unwinding drive assembly 23 and the rewinding drive motor 91, the printing paper unwinding roller 22, the printing paper rewinding roller 32 and the second tensioning roller 42 rotate synchronously during the lamination process, making the rewinding movement process of the printing paper 200 smoother.

[0061] In this embodiment, the unwinding drive assembly 23 includes a motor and a gear transmission module provided between the output end of the motor and the printing paper unwinding roller 22 .

[0062] To sum up, the lower roller body is replaced by the heating roller 5, and the traditional fixed upper roller body is replaced by the movable film winding mechanism 7. When laminating, the film winding mechanism 7 is started to drive the film 600 to move toward the heating roller 5, so as to adhere the film 600 to the printing paper 200 and press the printing paper 200 against the heating roller 5, so that the lamination is completed by the cooperation of the film winding mechanism 7 and the heating roller 5, so that printing paper of any thickness can be processed without manual adjustment. It is practical and convenient, and the processing efficiency is greatly improved.
