[0025] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 4 As shown, the utility model provides a high-precision plastic product trimming device, comprising a protective box 1, a sandblasting structure 2 is installed inside the protective box 1 through a displacement structure 3, and a fixing structure 4 is provided at the bottom end of the inner part of the protective box 1;

[0027] The sandblasting structure 2 includes a sand box 201 fixedly mounted on the top of the outer surface of the protective box 1. The front end of the sand box 201 is connected to an air pump 202 via a through-inserted pipe. The air pump 202 is fixed to the protective box 1 by bolts. The bottom end of the air pump 202 extends through the protective box 1 through a hose and is plugged with a plurality of nozzles 203.

[0028] The fixed structure 4 includes a telescopic hydraulic rod 401 fixedly installed at the bottom end of the protective box 1. A storage plate 402 is fixedly provided on the top of the telescopic hydraulic rod 401. A plurality of fixed suction cups 403 are evenly provided on the top of the storage plate 402.

[0029] refer to Figure 1 、 Figure 2 and Figure 4 The bottom ends of several fixed suction cups 403 are connected with suction cup air pumps 404 by means of connecting hoses. The suction cup air pumps 404 are fixedly installed at the bottom end of the protective box body 1. The tops of several fixed suction cups 403 are adsorbed and placed with plastic product bodies 5. The front of the protective box body 1 is symmetrically equipped with two box doors 6 through hinges. The fronts of the two box doors 6 are fixedly equipped with handles 7.

[0030] The above solution is adopted: the suction cup air pump 404 generates suction and transmits it to several fixed suction cups 403 to adsorb and fix the plastic product body 5, avoiding blocking the positions on the sides of the plastic product body 5 that need to be trimmed, so that the trimming action can be carried out accurately and comprehensively.

[0031] refer to Figure 2 and Figure 3 The displacement structure 3 includes a longitudinal slider 301 installed on the top of the nozzles 203. The top of the longitudinal slider 301 is slidably installed in the longitudinal slot 303 corresponding to the bottom of the device box 302. The outside of the longitudinal slider 301 is plugged with a longitudinal screw rod. The two ends of the longitudinal screw rod are rotatably installed in the longitudinal slot 303. The front end of the longitudinal screw rod extends through the device box 302 and is plugged with a driven pulley 304. One side of the driven pulley 304 is connected to the driving pulley 305 by the power of the transmission belt. The rear end of the driving pulley 305 is installed through the drive shaft. There is a motor 306, which is fixedly installed on the equipment box 302. A horizontal slider 307 is fixedly installed on the top of the equipment box 302. A horizontal screw rod 308 is inserted through the inside of the horizontal slider 307. Both ends of the horizontal screw rod 308 are rotatably installed on the protective box 1. One end of the horizontal screw rod 308 extends through the protective box 1 and is inserted with a motor 2 309. One end of the motor 2 309 is fixedly installed on the protective box 1. The top of the horizontal slider 307 is slidably inserted into the horizontal slide groove 3010 corresponding to the top of the inner top of the protective box 1.

[0032] The above scheme is adopted: Motor 2 309 controls the transverse screw 308 to drive the transverse slider 307 to perform directional displacement along the transverse groove 3010, so as to control the transverse displacement of several nozzles 203 and avoid the problem of insufficient transverse sandblasting displacement distance. Motor 1 306 controls the active pulley 305 and the driven pulley 304 to transmit power, control the longitudinal screw to rotate synchronously, and then drive the longitudinal slider 301 to slide longitudinally along the longitudinal groove 303, thereby controlling the longitudinal displacement of several nozzles 203.

[0033] During use, the plastic product body 5 is placed on the storage plate 402, the suction cup air pump 404 generates suction and transmits it to the several fixed suction cups 403 to adsorb and fix the plastic product body 5, the telescopic hydraulic rod 401 controls the up and down displacement of the plastic product body 5 to approach the several nozzles 203, the motor 2 309 controls the transverse screw 308 to drive the transverse slider 307 to perform directional displacement along the transverse slide 3010, so as to control the transverse displacement of the several nozzles 203, the motor 1 306 controls the active pulley 305 and the driven pulley 304 to transmit power, control the synchronous rotation of the longitudinal screw, and then drive the longitudinal slider 301 to slide longitudinally along the longitudinal slide 303, thereby controlling the longitudinal displacement of the several nozzles 203, the air pump 202 adsorbs the gravel filled in the gravel box 201 and transports it to the several nozzles 203 for spraying, continuously hitting the edge of the plastic product body 5 to remove burrs.

[0034] To sum up: this high-precision plastic product trimming device generates suction through a suction cup air pump 404 and transmits it to a number of fixed suction cups 403 to adsorb and fix the plastic product body 5, solving the problem that the existing equipment uses two telescopic rods to control the up and down displacement of the top splint to clamp or release the high-precision plastic product placed on the bracket, but because the splint will block part of the top area of ​​the high-precision plastic product, resulting in blind spots in the trimming process.
