[0027] Example 1

[0028] like Figures 1 to 4 As shown, the present embodiment provides a film roll clamping device for a laminating machine, including a laminating table 1, on the surface of which a film winding roller 2, a limiting roller 3 and a fixing part are sequentially mounted; a baffle plate 11 is mounted on an opposite side of the surface of the laminating table 1, and the film winding roller 2 and the limiting roller 3 are mounted on the side wall surface of the baffle plate 11 close to the surface of the laminating table 1, and the film winding roller 2, the limiting roller 3, the film pressing block 4 and the fixing part are all arranged in a direction perpendicular to the baffle plate 11.

[0029] Among them, both the film rolling roller 2 and the limiting roller 3 are provided with a rotating shaft 21, and the end of the rotating shaft 21 away from the film rolling roller 2, or the end of the rotating shaft 21 away from the limiting roller 3 is penetrated through the side wall surface of the baffle 11, and the rotating shaft 21 is configured with a driving motor 22 to achieve the effect of controlling the rotation angle and rotation speed of the film rolling roller 2 and the limiting roller 3.

[0030] In this embodiment, the fixing part is a rack 5, which is protruding from the surface of the coating table 1. The rack 5 is arranged on the side of the coating area away from the film rolling roller 2, and the rack 5 is arranged in the same direction as the film rolling roller 2. The side wall surface of the film rolling roller 2 can be used to cover the film roll.

[0031] In this embodiment, a film pressing block 4 is also arranged on the surface of the film pressing platform 1. The film pressing block 4 is located between the limiting roller 3 and the fixing part, and the film pressing block 4 is slidably connected to the surface of the film pressing platform 1. A film pressing area is arranged on the surface of the film pressing platform 1, and an elastic layer 43 is arranged at the bottom of the film pressing block 4. The bottom surface of the film pressing block 4 can abut against the surface of the film pressing area. The film pressing block 4 is mainly used for laminating the surface of the material. Among them, the elastic layer 43 at the bottom of the film pressing block 4 is made of rubber, which can enhance the laminating effect of the film pressing block 4 on the laminating and improve the bonding strength between the laminating and the material surface.

[0032] In this embodiment, an anti-skid layer 31 is provided on the side wall of the limiting roller 3. The anti-skid layer 31 can be made of a flexible cloth material wrapped around the side wall of the limiting roller 3 to reduce the smoothness between the roll film and the limiting roller 3 to avoid problems such as displacement of the roll film.

[0033] In this embodiment, a groove 12 is provided at the top of the baffle 11 near the film pressing block 4, and recesses 41 are provided at both ends of the bottom of the film pressing block 4, and the recesses 41 and the groove 12 can be mortise and tenon connected; a stopper 42 is arranged on the side of the film pressing block 4 near the recess 41, and the stopper 42 is arranged on the side of the baffle 11 away from the surface of the coating table 1.

[0034] In this embodiment, a plurality of limit strips 14 are provided on the surface of the groove 12 at the top of the baffle 11 to control the operator to maintain a relatively uniform and slow speed when pushing the film pressing block 11, so as to better complete the film laminating process.

[0035] In this embodiment, a placing plate 13 is laid on the surface of the coating area, and the top of the protrusion of the rack 5 is arranged beyond the surface of the placing plate 13 .

[0036] When using the film roll clamping device of the laminating machine of this embodiment, first remove the film pressing block 4, place the paper or cardboard to be coated on the surface of the storage plate 13, and then pull the film roll on the surface of the film roll roller 2. The film roll first passes through the top of the limiting roller 3, and then is pulled to the rack 5, and the film roll is fixed by the tooth tip of the rack 5; then the film pressing block 4 is mortised with the top of the baffle 11, and starting from the side close to the rack 5, the film pressing block 4 is pushed toward the film roll roller 2. This process can press the film roll onto the surface of the material to achieve the laminating process. In the process, if bubbles, unevenness, etc. are found in the laminating film, the film pressing block 4 can be moved in time to loosen the film roll to a certain extent before laminating again.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
