[0030] Reference Figure 1 As shown, the utility model provides a technical solution: a mylar sheet cutting device, comprising an operating table 1, a bracket 2 is fixedly connected to the lower surface of the operating table, a first mounting plate 3 is fixedly connected to the upper surface of the operating table 1, a second mounting plate 4 is fixedly connected to the upper surface of the operating table, a cutting machine 5 is installed on the side where the first mounting plate 3 and the second mounting plate 4 are close to each other, a cutting groove is opened on the upper surface of the operating table 1, a collecting device 6 is provided on the lower surface of the operating table 1, and a limiting device 7 is provided on the upper surface of the operating table.

[0031] The specific configuration and function of the collecting device 6 and the limiting device 7 will be described in detail below.

[0032] Reference Figures 1-4 As shown, in this embodiment, the collection device 6 includes a hollow plate 61. Two slide bars 63 are fixedly connected to the side of the hollow plate 61 facing away from the operating table 1. A collection box 62 is mounted on the surfaces of the two slide bars 63. The collection box 62 can collect the Mylar sheet debris that passes through the cutting slots. The hollow plate 61 and slide bars 63 allow the collection box 62 to be installed. A positioning plate 69 is fixedly connected to the surface of the bracket 2. A handle 64 is fixedly connected to the side of the collection box 62 facing away from the positioning plate 69. The positioning plate 69 can be used to position the collection box 62 during installation, and the handle 64 can facilitate the movement of the collection box 62.

[0033] A rotating plate 65 is rotatably connected to the side of the hollow plate 61 near the handle 64. The rotating plate 65 fits tightly against the collection box 62. A square rod 66 is slidably connected to the inner wall of the rotating plate 65. The square rod 66 is slidably connected to the inner wall of the hollow plate 61. The rotating plate 65 can limit the position of the collection box 62, and the square rod 66 can limit the rotation of the rotating plate 65. A pull plate 68 is fixedly connected to the end of the square rod 66 away from the hollow plate 61. A first spring 67 is mounted on the surface of the square rod 66, and the two ends of the first spring 67 are fixedly connected to the pull plate 68 and the rotating plate 65, respectively. The pull plate 68 facilitates the movement of the side rod 66, and the first spring 67 can limit the position of the side rod 66.

[0034] Reference Figure 1 and Figure 2 as well as Figure 5 As shown, specifically, the limiting device 7 includes two pressing plates 71, both mounted on the upper surface of the operating table 1. A slide groove is defined on the side of the first mounting plate 3 and the second mounting plate 4 that is adjacent to each other. Sliders 72 are slidably connected to the surfaces of the slide grooves on the first mounting plate 3 and the second mounting plate 4. Sliders 72 are fixedly connected to the pressing plates 71. The provision of slides 72 ensures that the pressing plates 71 can move, thereby accommodating the cutting of Mylar sheets of varying sizes. The provision of pressing plates 71 also limits the position of the Mylar sheets, minimizing their deflection during the cutting process.

[0035] The inner wall of the slider 72 is slidably connected to a fixed rod 73, which is fixedly connected to the surface of the slide groove on the first mounting plate 3 and the second mounting plate 4. A second spring 74 is mounted on the surface of the fixed rod 73, and the two ends of the second spring 74 are fixedly connected to the slider 72 and the first mounting plate 3 and the second mounting plate 4, respectively. The provision of the fixed rod 73 can limit the position of the second spring 74, and the provision of the second spring 74 can also limit the position of the slider 72. Two limiting rods 76 are fixedly connected to the upper surface of the operating table 1. Three ball bearings 75 are rotatably connected to the side of each pressure plate 71 away from the limiting rods 76. The provision of the limiting rods 76 can minimize the deviation of the cut mylar sheets when they are collected, facilitating their collection. The provision of the ball bearings 75 can facilitate the position of the pressure plate 71 to be limited by the mylar sheets.

[0036] Working principle: when using the Mylar sheet cutting device to cut the Mylar sheet, first move the Mylar sheet close to the operating table 1 so that it is between the first mounting plate 3 and the second mounting plate 4, and then cut the Mylar sheet through the cutting machine 5. At the same time, the debris generated by cutting the Mylar sheet passes through the cutting groove on the operating table 1, and the debris enters the collection box 62 through the hollow plate 61. When the collection box 62 needs to be cleaned, pull the pull plate 68 to drive the square rod 66 to slide on the inner wall of the rotating plate 65, so that the square rod 66 moves away from the hollow plate 61, and the restriction on the position of the rotating plate 65 is released. Then, the rotating plate 65 is rotated away from the collection box 62, and the pull plate 68 is released. Under the action of the elastic force of the first spring 67, the square rod 66 moves close to the hollow plate 61, and the rotating plate 65 is released. The position of the plate 65 is limited, and the collection box 62 is moved away from the positioning plate 69 on the bracket 2 through the handle 64. After the collection box 62 is cleaned, the collection box 62 is moved close to the slide bar 63, and the pull plate 68 is pulled away from the rotating plate 65. The rotating plate 65 is rotated close to the collection box 62, and the pull plate 68 is released. Under the action of the elastic force of the first spring 67, the square rod 66 is close to the hollow plate 61, and the position of the rotating plate 65 is limited to complete the installation of the collection box 62. By setting up the collection device 6, the Mylar sheet debris passing through the cutting groove on the operating table 1 can be collected synchronously during the process of cutting the Mylar sheet using the Mylar sheet cutting device, thereby reducing the workload of cleaning the Mylar sheet debris and improving the efficiency of cleaning the Mylar sheet debris.

[0037] The cam 72 is pressed against the top of the cam 73 to release the force of the spring 74 so that the cam 73 can be easily moved after the cam 73 is lifted up and the work piece 70 is in a state of emergency.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
