[0026] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 The film cutting detection device comprises a film supply mechanism 1, a cutting mechanism 2 and an optical detection mechanism 3. The film supply mechanism 1 is arranged at the side of the cutting mechanism 2, and the optical detection mechanism 3 is arranged below the cutting mechanism 2.

[0028] Specifically, the film supply mechanism 1 includes a film supply frame 101 and a film supply base 102, and the film supply frame 101 and the film supply base 102 are fixedly connected by two columns 103. Locking wheels 104 are also provided at the four corners below the film supply base 102, so as to facilitate the overall migration or positioning and locking of the film cutting detection device.

[0029] See also Figure 1 The aforementioned cutting mechanism 2 includes a transparent cutting table 201, and the transparent cutting table 201 is fixedly connected to the aforementioned film supply base 102 through a connecting rod, thereby fixing the cutting mechanism 2 and the film supply mechanism 1 to prevent positional deviation from occurring during the film material cutting process, thereby affecting the cutting effect. In this way, it can be ensured that the relative position of the transparent cutting table 201 and the film supply frame 101 is always fixed and vertical, so that the film is parallel to the aforementioned transparent cutting table 201 after being laid flat, which is convenient for measuring the size and cutting.

[0030] In addition, see Figures 2 to 3, a fixing mechanism 4 is arranged on the aforementioned column 103, and the fixing mechanism 4 is used to limit and fix the film material to be cut. Specifically, the fixing mechanism 4 includes an upper fixing block 401 and a lower fixing block 402, and the upper fixing block 401 and the lower fixing block 402 are fixedly connected by setting a locking nut on the upper fixing block 401. In the utility model, a first arc groove (not shown in the figure) is provided on the lower end surface of the aforementioned upper fixing block 401, and a second arc groove (not shown in the figure) is provided on the upper end surface of the aforementioned lower fixing block 402, and the first arc groove and the second arc groove cooperate to form a hole for accommodating a film supply roller 403, and the film material to be cut is sleeved on the film supply roller 403. When it is necessary to discharge the material, the film supply roller 403 sleeved with the film material to be cut is first mounted on the second arc groove of the lower fixing block 402, and then the upper fixing block 401 is buckled down and tightened with a locking nut to complete the feeding operation.

[0031] The two ends of the film supply roller 403 are respectively sleeved with a rolling bearing 4030, and the side of the rolling bearing 4030 close to the column 103 is fixedly connected with a flange 4031, and the side of the flange 4031 close to the column 103 is fixedly connected with a limit block 4032. That is, the flange 4031 is located between the rolling bearing 4030 and the limit block 4032. On the one hand, the film material to be cut sleeved on the film supply roller 403 can be limited and fixed, and on the other hand, by providing the rolling bearing 4030, the film material can be easily unfolded from the roller.

[0032] In this utility model, refer to Figure 1 , the aforementioned transparent cutting table 201 is provided with a horizontal scale and a vertical scale respectively. The vertical scale is provided along the discharge direction of the film material, and the horizontal scale is perpendicular to the aforementioned vertical scale and parallel to the setting direction of the aforementioned film supply roller 403. In addition, a slide rail 2010 is provided on both sides of the transparent cutting table 201, i.e., the outer edge of the vertical scale, and a slide bar 2011 is slidably provided on the slide rail 2010, and the slide bar 2011 is connected to the blade assembly 5. Therefore, by moving the slide bar 2011 on the slide rail 2010, combined with the aforementioned horizontal scale and vertical scale, the required size of the cut film material can be controlled.

[0033] See also Figure 4 The aforementioned blade assembly 5 includes a cross-cutting blade 501 and a vertical cutting blade 502. The cross-cutting blade 501 is used to cut the film material along a direction parallel to the aforementioned horizontal scale, and the vertical blade 502 is used to cut along a direction parallel to the aforementioned vertical scale. Specifically, the blade assembly 5 can be translated horizontally on the aforementioned slide bar 2011, and the cross-cutting blade can cut the horizontal edge of the film when translated. Simultaneously, the slide bar can be translated vertically, that is, along the direction of the slide rail 2010, and the vertical cutting blade can cut the vertical edge of the film when translated.

[0034] In this utility model, refer to Figure 1 The aforementioned optical detection mechanism 3 includes a backlight light box frame 301 arranged below the aforementioned transparent cutting table 201, a light-emitting lamp board 302 is fixed to the inner surface of the backlight light box frame 301, and an optical diffusion plate is arranged above the light-emitting lamp board 302. The optical diffusion plate can make the light emitted by the lamp beads on the light-emitting lamp board 302 evenly atomized, which looks softer and improves the experience. After the film is spread flat on the transparent cutting table 201, the size is measured according to the vertical and horizontal scales around the platform, and it is ready to be cut. Before cutting, light up the light-emitting lamp board 302, and the quality of the flat film can be checked through light. If there are scratches or stains, the corresponding area should be discarded to improve the cutting effect of the film material without affecting subsequent use.

[0035] In summary, the film cutting detection device in the utility model can adjust the size of the cut films according to different requirements, ensure the stability of the device during the cutting process, and the cutting operation is simple, which is conducive to improving the cutting quality control.
