[0016] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate the understanding of technicians.

[0017] like Figure 1-4As shown, the utility model provides a device for preventing fragments from splashing and collecting powder coating tablet crushers, comprising a protective frame 1, an automatic cleaning roller 2, and a negative pressure suction collection device 3 installed on a frame; the protective frame 1 is installed on the top of the end of the conveyor belt connected to the crushing roller 4 of the tablet crusher, the automatic cleaning roller 2 is evenly rotated and installed on the inner wall of the protective frame 1 through a bearing, and is connected to the motor installed on the frame, and the side walls of the automatic cleaning roller 2 are evenly provided with rubber strips 21 for cleaning the fragments remaining on the frame inside the protective frame 1; the discharging end of the tablet crusher is connected with a receiving trough 5 for receiving powder coating fragments; the negative pressure suction collection device 3 is installed on the tablet crusher, and its negative pressure suction end is arranged in front of the crushing roller 4. When the utility model is working, the flake powder coating after cooling and solidification is transmitted to the tablet crusher at the end along the conveyor belt, and is crushed into fragments by the crushing roller 4 and falls into the receiving trough 5 below. The splashed fragments are blocked by the protective frame 1 and fall on the frame inside the protective frame 1. Through the rotation of multiple automatic cleaning rollers 2, the rubber strip 21 sweeps the fragments to the end of the frame and falls into the receiving trough 5. The negative pressure suction end of the negative pressure suction collection device 3 attracts the fragments splashed when the crushing roller 4 is crushed and the fragments remaining on the frame, thereby reducing the splashing of the fragments and collecting the remaining fragments. The protective frame 1 of the utility model can block the fragments splashed after the crushing roller 4 is crushed, preventing the fragments from splashing to the outside and injuring the staff, or falling to the ground to cause waste of resources. The fragments splashed on the frame are swept into the receiving trough 5 by the automatic cleaning roller 2. The negative pressure suction collection device 3 can also collect the fragments splashed when the crushing roller 4 is crushed, thereby reducing the outward splashing of the fragments, avoiding the need for secondary cleaning of the fragments and increasing labor costs.

[0018] The negative pressure suction collection device 3 includes a plurality of suction pipes 31, a collection box 32, and a negative pressure pipe 33. The collection box 32 is installed at the end of the tablet crusher. The suction ends of the plurality of suction pipes 31 are arranged in parallel in front of the crushing roller 4. The other end of the suction pipe 31 is connected to the top of the collection box 32. The end of the negative pressure pipe 33 is connected to the collection box 32, and the other end is connected to the negative pressure pump. The negative pressure pump generates negative pressure in the collection box 32 through the negative pressure pipe 33, so that the suction pipe 31 attracts the fragments on the frame and the fragments splashed by the crushing roller 4, and stores them in the collection box 32, so as to collect the fragments splashed during the crushing, avoid the secondary cleaning of the fragments, and improve the efficiency of powder coating production.

[0019] The collecting box 32 is arranged above the receiving trough 5, and the bottom of the collecting box 32 is an open structure, and a cover plate 34 is hinged at the opening, and the free end of the cover plate 34 is connected to the side wall of the collecting box 32 through a locking structure 35. When the moving debris is stored in the collecting box 32, the cover plate 34 at the bottom of the collecting box 32 is opened through the locking structure 35, so that the debris automatically falls into the receiving trough 5 below, thereby facilitating the collection and recycling of the debris into the receiving trough 5, waiting for the next grinding operation.

[0020] The edge of the cover plate 34 is provided with a rubber sealing ring 36 which is sealed with the collection box 32. The rubber sealing ring 36 can make the cover plate 34 fit tightly with the collection box 32, avoid air leakage at the connection between the collection box 32 and the cover plate 34, increase the negative pressure attraction of the suction tube 31, and improve the suction effect of the suction tube 31.

[0021] The locking structure 35 includes a connecting rod 351, a screw rod 352, a fixed block 353, and a rotating block 354. One end of the connecting rod 351 is hinged at the end of the cover plate 34, and the other end is rotatably connected to the lower end of the screw rod 352 through a bearing. The fixed block 353 is installed on the side wall of the collection box 32, and the rotating block 354 is rotatably installed on the inner wall of the through hole opened on the fixed block 353. The rotating block 354 is threadedly connected to the screw rod 352. By rotating the screw rod 352, the screw rod 352 is threadedly rotated on the rotating block 354 and rotated relative to the connecting rod 351. The screw rod 352 moves downward to push the cover plate 34 to rotate downward and open. The connecting rod 351 is hinged to the cover plate 34, and the rotating block 354 rotates, so that the angle of the screw rod 352 is deflected, so that the cover plate 34 can be opened normally, and the fragments automatically slide into the receiving trough 5. The locking structure 35 facilitates the closing and opening of the cover plate 34, so that the fragments are conveniently recovered into the receiving trough 5.

[0022] The upper end of the screw rod 352 is provided with a knob 355 for facilitating the rotation of the screw rod 352. The screw rod 352 can be conveniently and labor-savingly rotated by the knob 355, so as to facilitate the opening and closing of the cover plate 34.

[0023] Working process:

[0024] When the utility model is working, the flaky powder coating after cooling and solidification is transmitted to the tablet crusher at the end along the conveyor belt, broken into pieces by the crushing roller 4, and falls into the receiving trough 5 below, and the splashed pieces are blocked by the protective frame 1 and fall on the frame inside the protective frame 1. Through the rotation of multiple automatic cleaning rollers 2, the rubber strip 21 sweeps the pieces to the end of the frame and falls into the receiving trough 5. The negative pressure suction end of the negative pressure suction collection device 3 attracts the pieces splashed by the crushing roller 4 when it is broken, and attracts the pieces remaining on the frame, and stores them in the collection box 32. By rotating the screw rod 352, the screw rod 352 moves downward to push the cover plate 34 to rotate downward and open, so that the pieces in the collection box 32 automatically slide into the receiving trough 5.

[0025] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
