DETAILED DESCRIPTION
[0015] In the description of the preferred embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate link; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0016] To better understand this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.
[0017] like Figure 1 , 2 As shown, a photosensitive material plate punching device includes a frame 1, on which a conveyor roller 2 driven by a conveyor motor is mounted. During production, the conveyor roller transports the photosensitive material plate. Punching rollers 3 and liner rollers 4 driven by punching motors are located on both sides of the frame. Multiple punching tubes 37 are surrounding the punching rollers, and each punching tube has a cutting edge 371 at its free end. Liner rollers are also mounted on the frame. The punching rollers and liner rollers are respectively mounted on both sides of the photosensitive material plate and arranged opposite to each other. The punching tubes act on the side of the photosensitive material plate to form mounting holes on the side. One punching roller and its corresponding liner roller constitute a set. A punching assembly; characterized in that: there are at least two punching assemblies, namely a first punching assembly 51 at the rear and a second punching assembly 52 at the front, wherein the punching roller and the liner roller of the first punching assembly are respectively a first punching roller 31 and a first liner roller 41, and the punching roller and the liner roller of the second punching assembly are respectively a second punching roller 32 and a second liner roller 42, wherein the first punching roller and the second punching roller are located at different positions on the upper and lower parts of the photosensitive material plate, and the mounting holes formed by the first punching roller and the mounting holes formed by the second punching roller on the photosensitive material plate are spaced apart.
[0018] The edges of the photosensitive material plate are biased towards the area where the perforating rollers act. The above-mentioned arrangement of this utility model allows the edges of the photosensitive material plate to alternately bias to both sides. During the process of biasing to both sides, such biases will be mutually eliminated or reduced, thereby achieving the effect of making the sides of the photosensitive material plate flatter.
[0019] To elaborate further, such as Figure 3 As shown, the liner roller has a groove 44 corresponding to the perforated tube.
[0020] To elaborate further, such as Figure 4 As shown, the liner roller has a layer of rubber material 45.
[0021] The utility model discloses above setting, on the photosensitive material board more easily form mounting hole, the thickness of rubber material layer is far more than the height of blade part, and blade part will not cut through rubber material layer, and rubber material layer can use for a long time, in addition, even if rubber material layer damage can replace.
[0022] Further, the first and second punch rollers are respectively on different sides of the photosensitive material plate.
[0023] As shown in Figure 2 the first punch roller is on the lower side of the photosensitive material plate, and the second punch roller is on the upper side of the photosensitive material plate, which can reduce the deformation of the side of the photosensitive material plate during punching.
[0024] The above is only a specific embodiment of the utility model, but the structural features of the utility model are not limited to this, any person skilled in the art in the field of the utility model makes the change or the modification and covers in the patent range of the utility model.
