[0016] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment 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.

[0017] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time: Example

[0018] Reference Figure 1-Figure 7 According to an embodiment of the utility model, a work frame of a plate processing engraving machine includes two front-to-back symmetrical fixed frames 10, and guide slides 11 are fixedly provided at the mutually close ends of the two fixed frames 10, and a fixed bracket 14 is slidably connected to the guide slides 11. The upper ends of the two fixed frames 10 are fixedly provided with cylinders 12, and the lower ends of the two cylinders 12 are dynamically connected to telescopic gas rods 13, and the lower ends of the telescopic gas rods 13 are fixedly connected to the fixed brackets 14. Two left-right symmetrical pressing rollers 15 are rotatably connected between the two front-to-back adjacent fixed brackets 14, and two left-right symmetrical card slots are provided at the upper ends of the two fixed brackets 14, and the card slots are located between the two pressure rollers 15. A fixed plate 16 is abutted between the two front-to-back adjacent card slots, and the fixed plate 16 is connected to the fixed bracket 14 by threads. Part 17 is threadedly fixedly connected, a fixed box 18 is fixedly provided at the lower end of the two fixed plates 16, and bristles 22 are fixedly provided at the ends of the two fixed boxes 18 that are away from each other, and the lower end of the bristles 22 is flush with the lower end of the pressure roller 15, and an air suction cavity 19 is opened in the two fixed boxes 18, and a filter screen 23 is fixedly provided on the lower side wall of the air suction cavity 19, and the two air suction cavities 19 are connected to each other on the sides away from each other and are connected to a uniformly distributed connecting cavity 21, and a connecting box 20 is fixedly provided at the ends of the two fixed boxes 18 that are away from each other, and the connecting box 20 is connected to the air extraction mechanism at the outer end through a connecting pipe, and a stabilizing plate is fixedly provided at the lower end of the two fixed boxes 18, and a threaded rod 24 is rotatably connected to the stabilizing plates at both ends, and a baffle 25 is threadedly connected to the outer periphery of the two threaded rods 24, and the lower end of the baffle 25 is inclined toward the bristles 22 on the same side;

[0019] The fixed frame 10 is fixedly arranged on the movable bracket, and a tool capable of moving forward and backward is arranged at the upper end of the two fixed plates 16 near each other. The tool moves forward and backward and the fixed frame 10 moves left and right to perform fine carving on the plate at the lower end.

[0020] The cylinder 12 is powered on to work, controlling the telescopic gas rod 13 at the lower end to extend downward, thereby pushing the two fixed brackets 14 connected to the lower end to slide downward synchronously, so that the pressure roller 15 rotatably connected to the fixed bracket 14 abuts against the plate at the lower end, and similarly, the bristles 22 abut against the plate. During the movement of the fixed bracket 10, the debris at the two bristles 22 is blocked, and the bristles 22 are flush with or even exceed the lower end of the pressure roller 15, preventing the debris from moving to the two pressure rollers 15;

[0021] The suction mechanism at the outer end works to generate suction at the connection box 20. When the connecting chamber 21 is connected to the suction chamber 19, the small particles of debris blocked by the bristles 22 are sucked through the lower end of the suction chamber 19, and filtered through the filter 23 to filter out large particles of debris and debris strips. The debris is blocked by the baffle 25. In the gap between the baffle 22 and the baffle 25, the small particles of debris can move upward to the filter 23 through the baffle 25, and enter the suction chamber 19 through the filter 23 of the cylinder 1 for collection.

[0022] The user can rotate the threaded rod 24 to make the baffle 25 threadedly connected to the threaded rod 24 slide left and right with the guide end of the fixed box 18, thereby changing the distance between the baffle 25 and the adjacent bristles 22;

[0023] The user removes the fixing plate 16 from the fixing bracket 14 by disassembling the threaded connector 17 , thereby replacing the bristles 22 and removing the debris in the suction cavity 19 .

[0024] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
