The discharge net 1 is semi-annular and has a plurality of extrusion holes evenly arranged. During processing, the material is discharged from the extrusion holes to obtain particles of corresponding sizes. The two ends of the discharge net 1 are connected with connecting ends 7, and the inner side of the connecting end 7 is provided with a sealing gasket, which can improve the sealing of the connection between the two and prevent the material from entering. The connecting end 7 is connected to a connecting mechanism for tightly connecting the two connecting ends 7. Two connecting mechanisms are provided and are relatively distributed. The connecting mechanism includes a clamping plate 6, two clamping blocks 13, and a plurality of springs 19. The clamping plate 6 is used to guide the two clamping blocks 13, and the clamping plate 6 is a U-shaped structure. The spring 19 is used to drive the clamping block 13 to move toward the center line direction of the clamping plate 6. The center line is Figure 5 The clamping plates 6 are connected to a driving mechanism for driving the two clamping plates 6 to move closer to or farther from each other, and the clamping plates 6 are connected to a positioning mechanism for positioning the clamping plates 6 .

[0024] When two discharge nets 1 need to be installed, the two discharge nets 1 are placed on the machine body 2, and the rotating handle 3 drives the rotating column 4 to rotate, driving the two clamping plates 6 to approach each other, so that the two connecting ends 7 are inserted into the corresponding clamping plates 6. When the end of the connecting end 7 is connected to the clamping plate 6, the clamping block 13 is pressed against the connecting end 7. At this time, the spring 2 19 is in a compressed state, thereby improving the stability of the connection between the two discharge nets 1, and at the same time clamped to the machine body 2, which is convenient for installing the discharge net 1. At this time, the positioning column 8 is connected to the positioning groove 16, which can realize the locking and fixing of the clamping plate 6 to prevent the discharge net 1 from loosening during the extrusion process and affecting the discharge effect.

[0025] When the discharging net 1 needs to be disassembled, the discharging net 1 of different apertures is replaced to meet the production of particles of different sizes. First, lift the positioning column 8 to separate its bottom from the positioning groove 16 to loosen the clamping plate 6, and then rotate the handle 3 to drive the rotating column 4 to rotate, which can drive the two clamping plates 6 away from each other, separate the clamping block 13 from the connecting end 7, and simultaneously loosen the two discharging nets 1, making it easy to disassemble the two discharging nets 1, replacing the traditional method of fixing with bolts, saving time and effort, and then install the discharging net 1 of the corresponding aperture on the machine body 2, and repeat the installation steps of the discharging net 1.

[0026] The connection mechanism also includes two inclined planes 14, two inclined planes 15, two guide grooves 17, multiple guide posts 18, multiple inner chambers 20, and multiple sliding blocks 21.

The coordinated use of the guide groove 17, the sliding block 21, and the guide post 18 makes the reciprocating movement of the clamping block 13 stable and not easy to be skewed or offset. The end of the inner cavity 20 is the e-surface. When the discharge net 1 is not clamped, the sliding block 21 is connected to the e-surface, which can prevent the pressing block 13 from being separated from the guide groove 17 and limit the pressing block 13. At this time, the spring 2 19 is still in a compressed state, and the inclined surface 14 is aligned with the inclined surface 2 15. When the two discharge nets 1 are just installed on the machine body 2, there is a certain distance between the two connecting ends 7, the two clamping plates 6 are close to each other, and the end of the connecting end 7 slides on the inclined surface 2 15, so that the two clamping plates 6 are close to each other. The clamping plates 6 continue to move, and the end of the connecting end 7 slides on the inclined surface 14. The sliding block 21 is separated from the e-surface, and the spring 2 19 is further compressed, so that the pressure exerted by the pressing block 13 on the connecting end 7 gradually increases until the end of the connecting end 7 is connected to the inner side of the clamping plate 6. The connecting end 7 stops moving, and the pressing block 13 is pressed against the connecting end 7, which can improve the tightness of the connection between the two connecting ends 7.

The handle 3 is fixedly connected to the end of the rotating column 4. The rotating column 4 runs through the body 2, and the rotating column 4 is used to drive the two L-shaped plates 5 to move closer to or farther from each other. The end of the L-shaped plate 5 is fixedly connected to the clamping plate 6. The rotating column 4 is rotatably connected to the body 2, and the rotating column 4 is threadedly connected to the two L-shaped plates 5, and the internal threads of the two L-shaped plates 5 are in opposite directions. The rotatable handle 3 drives the rotating column 4 to rotate, so that the two L-shaped plates 5 move closer to or farther from each other, thereby realizing that the two clamping plates 6 move closer to or farther from each other, which is convenient for fixing or loosening the two discharging nets 1.

[0030] The positioning mechanism includes a positioning column 8, a spring 9, a guide block 10, a vertical slot 11, and a positioning slot 16. The positioning column 8 passes through the L-shaped plate 5, the vertical slot 11 is arranged on the side of the clamping plate 6, the guide block 10 is slidably connected to the vertical slot 11, and the guide block 10 is fixedly connected to the positioning column 8. The spring 9 is sleeved on the positioning column 8, and the two ends of the spring 9 are connected to the L-shaped plate 5 and the guide block 10. The positioning slot 16 matches the bottom end of the positioning column 8. When the two clamping plates 6 approach each other, the bottom of the positioning column 8 slides in the slide slot 12 until the clamping plates 6 stop (the two discharging nets 1 are in the positioning state), the bottom of the positioning column 8 is aligned with the positioning slot 16, and the compressed spring 9 drives the guide block 10 to move downward, driving the positioning column 8 to move downward, so that the positioning column 8 is connected to the positioning slot 16, and the L-shaped plate 5 is realized, so as to prevent the clamping plate 6 from loosening due to vibration or misrotation of the handle 3 during the working process, thereby affecting the stability of the discharging net 1. The guide block 10 slides on the vertical groove 11 to ensure that the positioning column 8 is stably raised and lowered to prevent misalignment with the positioning groove 16 .

[0031] The machine body 2 is provided with a slide groove 12 , and the bottom of the clamping plate 6 is slidably connected to the slide groove 12 to improve the stability of the movement of the clamping plate 6 . The positioning groove 16 is provided in the slide groove 12 .

[0032] Working principle: When installing two discharging nets 1, the rotating handle 3 drives the rotating column 4 to rotate, so that the two clamping plates 6 are close to each other, and the clamping block 13 is pressed against the connecting end 7. The spring 19 is further compressed to improve the stability of the connection between the two discharging nets 1, and at the same time, it is clamped to the machine body 2, which is convenient for installing the discharging net 1. At this time, the positioning column 8 is connected to the positioning groove 16, which can lock and fix the clamping plate 6 to prevent the discharging net 1 from loosening and affecting the processing quality of the material. When the discharging net 1 needs to be disassembled and replaced, the positioning column 8 is manually lifted to separate the bottom of the positioning column 8 from the positioning groove 16, so as to loosen the L-shaped plate 5 and the clamping plate 6, and then the rotating handle 3 drives the rotating column 4 to rotate, so that the two L-shaped plates 5 move away from each other, and synchronously drive the two clamping plates 6 to move away from each other, so that the clamping block 13 is separated from the connecting end 7, so as to synchronously loosen the two discharging nets 1, which is convenient for disassembly, flexible and convenient to operate, and highly practical.
