Therefore, they cannot be understood as limitations on the present invention.

[0035] Reference Figure 1-7A rubber shell cutting device for metal workpieces includes a frame 1 with support legs 4 and a crushing box 2 fixed on the frame 1. The crushing box 2 is connected from top to bottom. The interior of the crushing box 2 is provided with a transmission chamber 6 and a control chamber 8 on both sides and a crushing chamber 7 in the middle through a partition. Two crushing rollers 12 are rotatably installed in the crushing chamber 7, as well as a filter drum 9 sleeved on the outside of the crushing roller 12. The filter drum 9 can collect the crushed rubber raw materials. A feed port is provided on the top of the filter drum 9, and the lower half of the filter drum 9 is in a grid shape to separate the collected crushed rubber raw materials and separate the completely crushed ones from the incompletely crushed ones. The partitions on both sides of the crushing chamber 7 are respectively rotatably installed with a swivel ring 10 and a swivel seat 11 that support the filter drum 9. The roller shafts at both ends of the crushing roller 12 pass through the partition and extend into the transmission chamber 6 and the control chamber 8, and the roller shafts of the two crushing rollers 12 are connected with a gearing 14 in the transmission chamber 6, and the gearing 14 realizes the synchronous operation of the two crushing rollers 12. The roller shaft of one of the crushing rollers 12 is connected to a reciprocating knocking assembly provided below the filter drum 9. The crushing roller 12 and the reciprocating knocking assembly are synchronized. The roller shafts at the other ends of the two crushing rollers 12 are connected with a rotating reciprocating assembly 16 between the swivel seat 11 in the control chamber 8. A motor 3 connected to one of the crushing rollers 12 is also installed on the side of the crushing box 2 to realize the rotation of the crushing roller 12 driven by the motor 3. In the process of the crushing roller 12 driven by the motor 3, the rotating reciprocating assembly 16 drives the filter drum 9 to rotate reciprocatingly, that is, it rotates reciprocatingly clockwise first and then counterclockwise, or first counterclockwise and then clockwise.

[0036] Reference Figure 1 and Figure 3 The tops of the transmission chamber 6 and the control chamber 8 are sealed to prevent the rubber raw materials from leaking into the transmission chamber 6 and the control chamber 8 when entering the crushing chamber 7. The transmission chamber 6 and the control chamber 8 are the same size.

[0037] Reference Figure 2 The meshing member 14 includes a circular gear fixedly sleeved on the roller shafts at the ends of the two crushing rollers 12. The two circular gears are meshed with each other. During the meshing process of the two circular gears, the motor 3 drives the two crushing rollers 12 to rotate synchronously in opposite directions.

[0038] Reference Figure 3-4 The top ends of both side walls of the crushing chamber 7 are fixedly connected with inclined limit baffles 13. The limit baffles 13 block both sides of the filter cylinder 9 to prevent the rubber raw materials from entering the two sides of the filter cylinder 9 and falling directly to the bottom of the frame 1. The bottom end of the limit baffle 13 extends to the feed port at the top end of the filter cylinder 9.

[0039] Reference Figure 3-4The top ends of the two limit baffles 13 are hinged with a guide plate 5, which is L-shaped. During the rotation of the guide plate 5 around the end of the limit baffle 13, the other end of the guide plate 5 extends under the feed port of the filter cylinder 9, making it convenient to feed the rubber raw materials through the guide plate 5 into between the two crushing rollers 12 during crushing.

[0040] Reference Figure 4 , cleaning components are installed on both sides of the lower end of the filter cartridge 9 in the crushing chamber 7 to comb the mesh of the grid part of the filter cartridge 9 to avoid clogging of the mesh. The cleaning components include: an electric push rod 20, which is obliquely symmetrically connected to the inner wall of the crushing chamber 7, and a brush 21, which is fixedly connected to the top of the two electric push rods 20 on the same side. During the extension of the electric push rod 20, it contacts the filter cartridge 9 along the length direction of the electric push rod 20, thereby being inserted into the mesh of the grid part of the filter cartridge 9.

[0041] Ginseng Figure 4-5 The reciprocating knocking assembly includes a rotating shaft 18 rotatably installed under the filter cartridge 9 and a plurality of cams 19 fixedly installed on the outside of the rotating shaft 18. The rotating shaft 18 is located in the middle position of the crushing box 2. During the rotation of the rotating shaft 18, the cam 19 reciprocates and knocks the bottom end of the filter cartridge 9. The cam 19 is made of plastic and has a certain elasticity. Only the top part of the cam 19 contacts the filter cartridge 9. Therefore, when knocking, the filter cartridge 9 will not be knocked up with too much force, resulting in damage to the filter cartridge. At the same time, the filter cartridge 9 will not affect the rotation of the cam 19.

[0042] Reference Figure 2 and Figure 5 The transmission member 15 includes: two sprockets, which are respectively fixedly mounted on the roller shaft end of one of the crushing rollers 12 and the end of the rotating shaft 18, and a chain connected to the outside of the two sprockets to achieve synchronous rotation of the rotating shaft 18 when the crushing roller 12 rotates.

[0043] Reference Figure 2 and Figure 6 One end of the swivel 11 is disc-shaped and rotatably connected to the inner wall of the crushing box 2, and the other end is annular and passes through the partition. One end of the filter cartridge 9 is inserted into the side of the swivel 11 and fixed to the swivel 11 by a screw 17. The screw 17 is screwed from the top of the swivel 11 to the end of the filter cartridge 9, thereby removing it. The other end of the filter cartridge 9 is fixed to the swivel 10, so that the swivel 10 and the swivel 11 support the filter cartridge 9.

[0044] Reference Figure 2 and Figure 7The rotating reciprocating assembly 16 includes: a shaft 161, which is coaxially fixedly connected to one end of the swivel seat 11; a transmission gear 162, which is fixedly mounted on the outer side of the shaft 161, and two half gears 163, which are respectively fixedly mounted on the roller shafts at the ends of the two crushing rollers 12, and the two half gears 163 intermittently mesh with the transmission gear 162. The ratio of the number of teeth on the half gear 163 to the number of teeth on the transmission gear 162 is 1:6, so that when the crushing roller 12 rotates one circle, the half gear 163 rotates one circle and drives the transmission gear 162 to rotate one-sixth of a circle, that is, the transmission gear 162 drives the swivel seat 11 and the filter cartridge 9 to rotate 60°. Similarly, the other half gear 163 also rotates one circle, driving the filter cartridge 9 to rotate 60°, thereby realizing the reciprocating rotation of the filter cartridge 9.

[0045] Working principle: During crushing, the first step is to start the motor 3 and guide the rubber raw materials into the crushing box 2. The rubber raw materials pass through the guide plate 5 and enter between the two crushing rollers 12. At this time, the second motor 3 drives the two crushing rollers 12 to rotate at the same time. At this time, the rubber raw materials will be squeezed by the crushing teeth on the two crushing rollers 12, so that the rubber raw materials are pressed into powder and crushed. The crushed rubber raw materials fall onto the filter drum 9. At the same time, the two crushing rollers 12 rotate and drive the two incomplete gears to rotate respectively. The two incomplete gears rotate in opposite directions and follow the principle of continuous rotation. The incomplete gear is meshed with the transmission gear 162, driving the transmission gear 162 to rotate first clockwise and then counterclockwise or first counterclockwise and then clockwise. Since the number of teeth of the incomplete gear is one-sixth of the number of teeth of the transmission gear 162, when one set of incomplete gears rotates one circle, the transmission gear 162 rotates one-sixth of a circle, i.e., 60°. The rotation of the transmission gear 162 drives the shaft 161 to rotate, and the rotation of the shaft 161 drives the rotating seat 11 to rotate. The rotation of the rotating seat 11 drives the filter drum 9 to rotate, and finally the filter drum 9 rotates back and forth in different directions, so that the rubber raw materials are quickly screened in the filter drum 9.

[0046] During screening, the motor 3 drives the crushing roller 12 to rotate, and the transmission assembly drives the rotating shaft 18 to rotate. The rotation of the rotating shaft 18 drives the cam 19 to rotate. During the rotation of the cam 19, the top of the cam 19 reciprocates and strikes the bottom surface of the filter drum 9, thereby accelerating the screening of the filter drum 9 until the crushing is completed.

[0047] After the crushing is completed, when the large particles of rubber raw materials need to be taken out, the screw 17 connecting the rotating seat 11 and the filter cylinder 9 is unscrewed, and the rotating shaft 18 is rotated and connected to the filter cylinder 9, and then the guide plate 5 is moved from Figure 4 Rotate to Figure 5 In the state shown, the rotation of the filter cartridge 9 is not disturbed. Finally, the rotating ring 10 drives the filter cartridge 9 to rotate 180° so that the feed port of the filter cartridge 9 faces downward. At this time, the rubber raw material rolls out of the crushing box 2 from the feed port of the filter cartridge 9.

[0048] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
