[0026] Please refer to Figures 1 - 5 , the present utility model provides a feeding device for processing modified plastic raw materials with dust reduction, including a feeding cylinder 4. A bracket plate 7 is fixed on the outer side wall of the feeding cylinder 4. The top of the bracket plate 7 is fixed with a motor 8 located at the top opening of the feeding cylinder 4. The output end of the motor 8 is fixed with a shaft rod 9 arranged coaxially with the feeding cylinder 4.

The top of the port cylinder 11 is fixed with an end head plate 10. A dust suction component 1 is arranged at the top of the end head plate 10. A cleaning component 3 for cleaning the dust suction component 1 is connected to the side surface of the shaft rod 9. When in use, the modified plastic raw materials are put into the inside of the port cylinder 11 through the top opening of the port cylinder 11. The motor 8 is started to work. The output end of the motor 8 drives the shaft rod 9 to rotate. The shaft rod 9 drives the crushing roller 12 to rotate. The raw materials fall and are delivered through the gap between the crushing roller 12 and the inner side wall of the feeding cylinder 4. During this process, the raw materials are crushed and refined by the plurality of arc bumps c 13 on the crushing roller 12, so as to eliminate the agglomeration in the raw materials and improve the refinement degree of the raw materials. The dust suction component 1 sucks and removes the flying dust particles emerging from the top port of the port cylinder 11, so as to effectively remove dust, avoid the pollution of the surrounding air environment caused by dust flying, improve the protection of workers. When the shaft rod 9 rotates, the shaft rod 9 synchronously drives the cleaning component 3 to clean the dust suction component 1, avoiding the problem of blockage of the suction holes of the dust suction component 1 and ensuring an efficient dust suction and reduction effect all the time.

[0027] Furthermore, as shown in Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically stating that the dust suction assembly 1 includes an annular seat 101 fixed to the side of the top end of the end head plate 10. A ventilation cavity 103 is provided in the annular seat 101. Suction holes 102 communicating with the ventilation cavity 103 are provided on the inner side surface of the annular seat 101. A plurality of suction holes 102 are provided and the plurality of suction holes 102 are equidistantly distributed. A dust collector 105 is fixed on the outer side wall of the feeding cylinder 4. A connecting pipe 104 is connected to the output end of the dust collector 105. One end of the connecting pipe 104 away from the dust collector 105 is communicated with the ventilation cavity 103. During specific operation, a negative pressure suction is formed in the connecting pipe 104 and the ventilation cavity 103 through the dust collector 105, so as to perform an enclosed suction and removal of the flying dust particles emerging from the top port of the port cylinder 11 through the plurality of suction holes 102, and suck them into the dust collector 105 for collection, thereby effectively removing dust, avoiding dust flying and polluting the surrounding air environment, and improving the protection of workers.

[0028] Further, as Figure 2 、 Figure 3 and Figure 4 shown, it is worth specifically stating that the cleaning assembly 3 includes a connecting rod 301 fixed to the side of the shaft rod 9.

Specifically during operation, the raw materials after crushing and refinement fall into the discharge pipe 5, and the raw materials are discharged through the bottom opening of the discharge pipe 5. The rotating crushing roller 12 synchronously drives the connecting rod 201 to rotate. The connecting rod 201 drives the metal elastic sheet 202 and the arc-shaped convex block a203 to rotate, so that the arc-shaped convex block a203 continuously rotates to contact the arc-shaped convex block b204. Through the cooperation of the arc-shaped convex block a203 and the arc-shaped convex block b204, the arc-shaped convex block a203 continuously knocks on the side wall of the discharge pipe 5, causing the discharge pipe 5 to vibrate continuously, accelerating the discharge of the raw materials in the discharge pipe 5 and avoiding the problem of material blockage during discharging.

[0030] The working process of this solution is as follows: When in use, the modified plastic raw materials are put into the inside of the port cylinder 11 through the top opening of the port cylinder 11.

During this process, the raw materials are crushed and refined by the multiple arc-shaped convex blocks c13 on the crushing roller 12, thereby eliminating the lumps in the raw materials. A negative pressure suction is formed in the connecting pipe 104 and the ventilation cavity 103 through the vacuum cleaner 105, so that the dust particles floating out from the top port of the port cylinder 11 are surrounded and sucked and removed through the multiple suction holes 102, and are sucked into the vacuum cleaner 105 for collection, thereby effectively removing dust. When the shaft rod 9 rotates, the shaft rod 9 synchronously drives the joint block 302 to rotate around the central axis of the annular seat 101 through the connecting rod 301, so that the cleaning brush bristles 303 brush and clean the suction holes 102. The raw materials after crushing and refinement fall into the discharge pipe 5, and the raw materials are discharged through the bottom opening of the discharge pipe 5. The rotating crushing roller 12 synchronously drives the connecting rod 201 to rotate. The connecting rod 201 drives the metal elastic sheet 202 and the arc-shaped convex block a203 to rotate, so that the arc-shaped convex block a203 continuously rotates to contact the arc-shaped convex block b204. Through the cooperation of the arc-shaped convex block a203 and the arc-shaped convex block b204, the arc-shaped convex block a203 continuously knocks on the side wall of the discharge pipe 5, causing the discharge pipe 5 to vibrate continuously and accelerating the discharge of the raw materials in the discharge pipe 5.

[0031] Furthermore, as Figure 2 and Figure 5As shown, it is worth specifically stating that there are multiple arc-shaped bumps b204, and the multiple arc-shaped bumps b204 are distributed in a ring shape; during specific operation, the multiple arc-shaped bumps b204 are provided to increase the knocking frequency of the arc-shaped bump a203 on the blanking pipe 5 and improve the discharging speed.

[0032] Furthermore, as shown in Figure 2 , Figure 3 and Figure 5 it is worth specifically stating that a rounded corner transition section 205 is provided at the corner of the metal elastic sheet 202, and a mounting bracket 6 is fixed on the outer side wall of the feeding cylinder 4; during specific operation, the provided rounded corner transition section 205 avoids stress concentration, and the feeding cylinder 4 is fixedly installed through the provided mounting bracket 6.

[0033] In summary: The output end of the motor 8 drives the shaft rod 9 to rotate. The shaft rod 9 drives the crushing roller 12 to rotate. The raw material falls and is fed through the gap between the crushing roller 12 and the inner side wall of the feeding cylinder 4. During this process, the multiple arc-shaped bumps c13 on the crushing roller 12 crush and refine the raw material, thereby eliminating the lumps in the raw material and improving the refinement degree of the raw material. The dust suction component 1 sucks and removes the flying dust particles emerging from the top port of the port cylinder 11, thereby effectively removing dust, avoiding dust flying and polluting the surrounding air environment, and improving the protection of workers. When the shaft rod 9 rotates, the shaft rod 9 synchronously drives the cleaning component 3 to clean the dust suction component 1, avoiding the problem of blockage of the suction holes of the dust suction component 1 and ensuring an efficient dust suction and dust reduction effect at all times. The rotating crushing roller 12 synchronously drives the connecting rod 201 to rotate. The connecting rod 201 drives the metal elastic sheet 202 and the arc-shaped bump a203 to rotate, so that the arc-shaped bump a203 continuously rotates to contact the arc-shaped bump b204. Through the cooperation of the arc-shaped bump a203 and the arc-shaped bump b204, the arc-shaped bump a203 continuously knocks on the side wall of the blanking pipe 5, causing the blanking pipe 5 to vibrate continuously and accelerating the discharge of the raw material in the blanking pipe 5.
