Description

TECHNICAL FIELD

[0001] The utility model relates to the field of breaking and sizing machine, especially to an antioxidant master batch breaking and sizing machine. BACKGROUND

[0002] The breaking and sizing machine is a processing equipment for breaking and sizing materials. After the particles of different specifications and shapes are processed, particles of basically the same shape and specification can be obtained. After the raw materials are added from the feeding port and fall into the conical working chamber, the rotary rotary knife produces a cyclone effect on the raw materials and throws the particles to the screen surface by centrifugal force.

After the material in the hopper 5 is discharged through the discharge port 8, it will enter the round shell 12 through the first feeding port 13.

The top end of the compression spring 24 is fixedly installed with the adjusting clamping head 25 corresponding to the adjusting groove 18. When the lever 22 is pushed upward, the lever 22 will drive the rotating rod 21 to rotate in the rotating hole 15. The rotating rod 21 will drive the rotating plate 20 to rotate.

The material in the hopper 5 can enter the round shell 12 through the opening size of the first feeding port 13. Until the compression spring 24 in the spring groove 23 is elastically pushed into the next adjusting groove 18 by the contraction and expansion operation, in this way, by pushing the lever 22, the rotating degree of the arc-shaped baffle 19 can be controlled. The arc-shaped baffle 19 can control the opening size of the first feeding port 13 to achieve the purpose of adjusting the material discharging speed and flow rate.

[0031] As shown in Figure 6 and Figure 7 , the crushing cylinder 26 is fixedly installed on the bottom front end of the support frame 1 and penetrates through the support frame 1. The outer wall rear end top of the crushing cylinder 26 is fixedly installed with the second feeding port 27. The second feeding port 27 and the discharge port 14 are fixedly installed with the connecting pipe 16. After the material in the round shell 12 is discharged through the discharge port 14, it will enter the crushing cylinder 26 through the second feeding port 27 from the connecting pipe 16.

[0032] As shown in Figure 6 and Figure 7As shown, the driving motor 28 is fixedly installed on the top surface of the crushing cylinder 26, and a rotary knife 29 is fixedly installed on the output end of the driving motor 28, and a plurality of crushing blades 30 are further fixedly installed on the outer wall of the guide rod of the rotary knife 29, and after the rotary knife 29 is driven to rotate by the driving motor 28, the crushing blades 30 will crush the material entering into the crushing cylinder 26, and the material crushed by the crushing blades 30 will be further crushed by the rotary knife 29 when entering into the sieve 33.

[0033] As shown in Figure 7 , the fixed ring 31 is fixedly installed on the inner wall of the crushing cylinder 26, and a group of left-right symmetrical L-shaped sockets 32 are arranged on the top surface of the fixed ring 31, which are used for disassembling and replacing the sieve 33.

[0034] As shown in Figure 6 and Figure 7 , a group of left-right symmetrical L-shaped clamping blocks 34 corresponding to the L-shaped sockets 32 are fixedly installed on the top surface of the sieve 33, and the sieve 33 can be used for crushing and screening the material by cooperating with the rotary knife 29, and the sieve 33 can be quickly disassembled from the crushing cylinder 26 after the sieve 33 is rotated clockwise to the point that it cannot be rotated.

[0035] The specific use principle and operation of the feeding mechanism 2, the control mechanism 3 and the crushing and granulating mechanism 4 when they are used in cooperation are as follows:

[0036] When the anti-oxidant master batch needs to be broken and sized, the other end of the suction pipe 9 is inserted into the bag, and the high-pressure fan 10 is turned on to vacuumize the inside of the hopper 5 through the suction pipe 11 from the suction port 6. After the inside of the hopper 5 is continuously vacuumized, a negative pressure suction force is generated, which is transmitted to the suction pipe 9 through the suction port 7. At this time, the suction pipe 9 sucks the anti-oxidant master batch particles in the bag and transports them to the hopper 5 through the suction port 7, realizing vacuum feeding. This can replace manual feeding, and is simple, convenient, time-saving and labor-saving, and improves work efficiency. When the anti-oxidant master batch stored in the hopper 5 is processed, the push rod 22 on the back wall of the circular shell 12 is pushed upwards, the push rod 22 drives the rotating rod 21 to rotate in the rotating hole 15 on the back wall of the rotating hole 15, the rotating rod 21 drives the rotating plate 20 to rotate, the rotating plate 20 drives the arc-shaped baffle 19 installed at the top to rotate, and the arc-shaped baffle 19 moves away from below the first feeding port 13 installed on the top of the circular shell 12 during rotation. At this time, the adjusting clamp head 25 protruding from the top of the push rod 22 moves out of the bottommost adjusting groove 18 in the inner wall of the arc-shaped plate 17 on the back wall of the circular shell 12. During continuous rotation of the push rod 22, the adjusting clamp head 25 loses the extrusion force of the inner wall of the arc-shaped plate 17, the compressed spring 24 in the spring groove 23 restores and extends, and pushes the adjusting clamp head 25 into the previous adjusting groove 18. In this way, the push rod 22 is positioned and the rotation position of the arc-shaped baffle 19 is controlled, so that the arc-shaped baffle 19 can control the opening degree of the first feeding port 13 after rotation. The more the push rod 22 rotates upwards, the larger the opening of the first feeding port 13, and vice versa. Similarly, as the arc-shaped baffle 19 gradually stops shielding the first feeding port 13, the anti-oxidant master batch in the hopper 5 enters the circular shell 12 through the opening between the first feeding port 13 and the arc-shaped baffle 19. The smaller the opening, the slower the anti-oxidant master batch discharging speed and the less the anti-oxidant master batch flow, and vice versa. Therefore, the problem of anti-oxidant master batch accumulation and blockage can be avoided to ensure normal processing of the anti-oxidant master batch. The anti-oxidant master batch entering the circular shell 12 is discharged through the discharge port 14 and enters the crushing cylinder 26 through the second feeding port 27 and the connecting pipe 16. At the same time, the drive motor 28 on the top of the crushing cylinder 26 drives the output end to rotate the rotary knife 29. During rotation, the plurality of crushing blades 30 on the knife rod of the rotary knife 29 can pre-crush the anti-oxidant master batch. After the anti-oxidant master batch is crushed, the rotary knife 29 cooperates with the sieve hopper 33 to rotate the rotary knife 29 to produce a swirling effect on the raw material, and the particles are thrown to the screen surface by centrifugal force.The particles are crushed into small particles between the rotary knife and the screen and discharged through the screen holes, which can ensure the crushing effect on the material. Finally, the antioxidant master batch material after crushing and granulating will fall from the bottom of the crushing cylinder 26. When the screen bucket 33 needs to be disassembled, the hand can be inserted into the crushing cylinder 26 from below the crushing cylinder 26, and the screen bucket 33 is rotated clockwise until it cannot be rotated, so that the horizontal part of the L-shaped clamping block 34 installed on the top surface of the screen bucket 33 is completely moved into the vertical part of the L-shaped clamping hole 32 opened on the top surface of the fixed ring 31 installed in the crushing cylinder 26, and then the screen bucket 33 is disassembled and taken out from the crushing cylinder 26. When installing, after the L-shaped clamping block 34 is inserted into the vertical part of the L-shaped clamping hole 32, the L-shaped clamping block 34 is rotated counterclockwise so that the horizontal part of the L-shaped clamping block 34 is clamped in the horizontal part of the L-shaped clamping hole 32 and cannot be rotated, and then the installation operation is completed. Thus, the screen bucket 33 can be conveniently disassembled and replaced.

[0037] The above is only the preferred embodiment of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, various improvements can be made to the present application without departing from the scope of the present application, equivalent parts can be substituted, or some technical features can be replaced equivalently. Any improvement, substitution or replacement within the spirit and principle of the present application shall be included in the protection scope of the present application.
