DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] Embodiment 1: A diaphragm deformation prevention die-cutting device comprises a workbench 1, a pair of pillars 2 are fixedly connected to both sides of the top of the workbench 1, a winding roller 3 is rotatably connected between the pillars 2 on both sides, and the winding rollers 3 on both sides are symmetrical at the center, a cylinder 5 is fixedly connected to the top of the workbench 1, the output end of the cylinder 5 passes through the bracket 4 and is connected to the upper pressing plate 6, and a pair of limit rods 14 are fixedly connected to the output top of the upper pressing plate 6, and the limit rod 14 passes through the bracket 4 and is slidably connected to the inside of the bracket 4, a cutting knife 20 is fixedly connected to the bottom of the upper pressing plate 6, and a flattening mechanism is arranged on the outside of the upper pressing plate 6, the flattening mechanism comprises a pair of rollers 13 and a pair of lower pressing plates 16, and the rollers 13 are respectively arranged on both sides of the upper pressing plate 6, the lower pressing plates 16 on both sides are slidably connected to the inside of the upper pressing plate 6, and the lower pressing plates 16 on both sides are symmetrically distributed on both sides of the cutting knife 20, and the upper pressing plate 6 is fixedly connected to both sides of the upper pressing plate 6. A mounting plate 9 is fixedly connected, a spring 10 is fixedly connected to the bottom of the mounting plate 9, and a rotating plate 11 is fixedly connected to the other end of the spring 10. Inner grooves 7 are provided on both sides of the upper pressure plate 6, and connecting columns 8 are fixedly connected to the inner grooves 7, and one end of the rotating plate 11 is rotatably connected to the outer wall of the connecting column 8, and the other end of the rotating plate 11 is fixedly connected to an inner rod 12, and a roller 13 is rotatably connected to the outer wall of the inner rod 12, and the roller 13 is cylindrical, two pairs of slide grooves 15 are provided inside the upper pressure plate 6, and a slider 17 is fixedly connected to the inner wall of the lower pressure plate 16, and the slider 17 corresponds to the slide groove 15, and the slider 17 is slidably connected in the slide groove 15, and the lower pressure plate 16 is L-shaped, and a fixing column 18 is fixedly connected to the bottom of the upper pressure plate 6, and a spring 2 19 is fixedly connected to the other end of the fixing column 18, and the bottom end of the spring 2 19 is fixedly connected to the lower pressure plate 16.

[0025] The diaphragm is wound around the winding roller 3 from one end of the workbench 1, and then the other end is fixed to the other end of the winding roller 3 by passing the bottom of the upper pressing plate 6. The cylinder 5 on the top of the bracket 4 is started to move the upper pressing plate 6 up and down. The upper pressing plate 6 is kept in a vertical state on the bracket 4 by the limit rod 14. The downward movement of the upper pressing plate 6 will drive the rollers 13 on both sides to move downward, so that the rollers 13 contact the workbench 1 and move to both sides. The rollers 13 are supported on the inner rod 12 through the rotating plate 11, causing the rotating plate 11 to move with the rollers 13 and be positioned and supported on the upper pressing plate 6 through the connecting column 8. In this process, the spring 10 slows down the speed of the rotating plate 11 and causes the rollers 13 to press the diaphragm to ensure that it remains flat during transportation and avoids wrinkles. At the same time, when the upper pressing plate 6 moves downward, the cutting knife 20 cuts the diaphragm. In order to prevent the diaphragm from deforming during cutting, the cutting knife 20 moves downward, driving the lower pressing plates 16 on both sides to move downward at the same time, so that they contact the diaphragm and position the diaphragm closest to the two sides of the cutting knife 20 through the spring 2 19. The lower pressing plate 16 is limited in the fixed column 18 to maintain vertical movement, ensuring that the diaphragm is not deformed during cutting, thereby improving work efficiency.

[0026] During operation, the staff first winds the diaphragm around the winding roller 3 at one end of the workbench 1, and then passes the other end of the diaphragm through the bottom of the upper pressure plate 6 and fixes it on the winding roller 3 at the other end. At this time, the cylinder 5 on the top of the bracket 4 is started, and the upper pressure plate 6 is driven to move up and down under the action of the cylinder 5, and the upper pressure plate 6 is limited on the bracket 4 by the limit rod 14, so when the upper pressure plate 6 moves, it is in a vertical state, and the downward movement of the upper pressure plate 6 will drive the rollers 13 on both sides to move downward. At this time, the rollers 13 gradually contact the workbench 1 and move toward the two pairs. The rollers 13 are supported on the inner rod 12 through the rotating plate 11, so the rotating plate 11 will rotate according to the movement of the rollers 13, and the rotating plate 11 is positioned and supported on the upper pressure plate 6 through the connecting column 8, and the elastic action of the spring 10 on the rotating plate 11 causes the rotation. When rotating, the plate 11 will slow down and drive the roller 13 to press the diaphragm, thereby flattening the diaphragm on the workbench 1 during transportation, thereby solving the problem of wrinkles during transportation. During the downward movement of the upper pressing plate 6, the diaphragm is cut by the cutting knife 20. Since the diaphragm is a soft material, in order to prevent deformation during cutting, when the cutting knife 20 moves downward, it will drive the lower pressing plates 16 on both sides to move downward at the same time, and the lower pressing plate 16 will first contact the diaphragm, and the elastic action of the spring 19 on the lower pressing plate 16 will drive the lower pressing plate 16 to locate the diaphragm closest to the two sides of the cutting knife 20, and the sliding block 17 is limited in the fixed column 18 to prompt the lower pressing plate 16 to move vertically. Through the cooperation between them, the diaphragm will not be deformed during cutting, which greatly improves the work efficiency.
