[0002] The present invention relates to the technical field of rubber processing, and more particularly to a waste treatment device for rubber processing and a method for using the same. Background Art

[0003] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under a small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a large molecular weight, greater than hundreds of thousands. After the rubber is processed into the required shape, some residue will remain. At this time, this residual rubber is called rubber waste.

[0004] In the prior art, the treatment of rubber waste requires first cooling the rubber waste with a coolant, and then crushing the rubber waste after it becomes brittle and hard. If the crushed rubber waste particles are large, they need to be crushed again until the particle size meets the requirements. Although some existing waste treatment devices for rubber processing can screen out rubber waste with larger particles, the collected large particles of rubber waste need to be taken out by the staff many times and poured into the processing device. The operation is repetitive and labor-intensive, and also increases the labor cost. Summary of the invention

[0016] A method for using a waste treatment device for rubber processing comprises the following steps:

[0017] Step 1: Pour the rubber waste into the feed pipe, the rubber waste enters the processing box through the feed pipe and falls onto the fixed plate, start the coolant circulation pump to transport the coolant in the coolant storage box to the cooling cavity in the fixed plate, so that the coolant cools the fixed plate, and the fixed plate cools the rubber waste. The rubber waste becomes hard and brittle when it is cold, start the electric push rod to drive the pressing plate to move downward to squeeze the rubber waste on the fixed plate, and the crushed rubber waste falls downward through the drop hole on the fixed plate;

[0018] Step 2: The crushed rubber waste falls between the two crushing rollers, and the motor is started to drive one of the crushing rollers to rotate forward, and the other of the two crushing rollers is driven to rotate reversely through two sets of mutually meshing gears to crush the crushed rubber waste, and the crushed rubber waste continues to fall downward onto the screen;

[0019] Step 3: When the gear rotates, it drives the first slide bar to make a circular motion, and the first slide bar squeezes the inner wall of the first slide groove on the swing plate, thereby driving the swing plate and the cam on the rotating shaft to swing back and forth, and the cam squeezes the lower surface of the second mounting frame, driving the screen to move upward, and the elastic force of the first spring makes the screen shake up and down, so as to screen the crushed rubber waste. Small particles of rubber waste pass through the screen and fall down into the second material receiving box, and large particles of rubber waste fall into the first material receiving box through the first feeding port;

[0020] Step 4: When the swing plate swings back and forth, it squeezes the second slide bar through the inner wall of the second slide groove, so that the swing plate drives the lifting plate and the first material receiving box on the lifting plate to move up and down on the outside of the processing box. When the first material receiving box moves upward, the elastic force of the second spring will drive the baffle plate upward to block the first feed port to prevent other large particles of rubber waste from falling directly to the ground. When the first material receiving box moves upward to the discharge port on one side and is connected with the second feed port on the processing box, the large particles of rubber waste collected in the first material receiving box will fall between the two crushing rollers again and be crushed for the second time, ensuring that the rubber waste is crushed thoroughly.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1) When the waste processing device for rubber processing is in use, when the motor drives the crushing roller to rotate, the gears at both ends of the crushing roller drive the swing plate to swing back and forth through the first slide groove and the first slide rod. When the swing plate swings back and forth, it drives the lifting plate and the first material receiving box on the lifting plate to move up and down on the outside of the processing box through the second slide groove and the second slide rod. When the first material receiving box moves upward to the discharge port on one side and is connected with the second feed port on the processing box, the large particles of rubber waste collected in the first material receiving box will fall between the two crushing rollers again and be crushed for the second time, which ensures that the rubber waste is completely crushed and realizes the purpose of automatically pouring the large particles of rubber waste into the interior of the processing device.

[0023] 2) When the waste processing device for rubber processing is in use, the swing plate will swing back and forth, driving the cam to swing synchronously through the rotating shaft, so that the cam can squeeze the second mounting frame upward, and the second mounting frame will compress the first spring when it moves upward. When the cam does not squeeze the second mounting frame, the elastic force of the compressed first spring will drive the second mounting frame to move downward, and the screen will shake up and down in this reciprocating manner, thereby screening the crushed rubber waste and preventing the rubber waste from clogging the screen.

4. A waste treatment device for rubber processing according to claim 3, characterized in that: The outside of the processing box (1) is fixedly connected to a control panel (28), and the motor (3), the electric push rod (1803) and the coolant circulation pump (1807) are all electrically connected to the control panel (28).

5. The method for using the waste treatment device for rubber processing according to any one of claims 1 to 4, characterized in that: The following steps are involved: Step 1: Pour the rubber waste into the feed pipe (29), the rubber waste enters the processing box (1) through the feed pipe (29) and falls onto the fixed plate (1801), start the coolant circulation pump (1807) to transport the coolant in the coolant storage box (1806) to the cooling chamber (1808) in the fixed plate (1801), so that the coolant cools the fixed plate (1801), and the fixed plate (1801) cools the rubber waste. The rubber waste becomes hard and brittle when it is cold, start the electric push rod (1803) to drive the pressing plate (1804) to move downward to squeeze the rubber waste on the fixed plate (1801), and the crushed rubber waste falls downward through the drop hole (1802) on the fixed plate (1801); Step 2: The crushed rubber waste falls between the two crushing rollers (4), and the motor (3) is started to drive one of the crushing rollers (4) to rotate in the forward direction, and the other of the two crushing rollers (4) is driven to rotate in the reverse direction through two sets of mutually meshing gears (5), so as to crush the crushed rubber waste, and the crushed rubber waste continues to fall downward onto the screen (1705); Step 3: When the gear (5) rotates, it drives the first slide bar (9) to make a circular motion. The first slide bar (9) squeezes the inner wall of the first slide groove (8) on the swing plate (7), thereby driving the swing plate (7) and the cam (1706) on the rotating shaft (6) to swing back and forth. The cam (1706) squeezes the lower surface of the second mounting frame (1703), driving the screen (1705) to move upward, and the elastic force of the first spring (1704) causes the screen (1705) to shake up and down, thereby screening the crushed rubber waste. Small particles of rubber waste pass through the screen (1705) and fall downward into the second material receiving box (30), while large particles of rubber waste pass through the first feed port (15) and fall into the first material receiving box (13); Step 4: When the swing plate (7) swings back and forth, it squeezes the second slide bar (11) through the inner wall of the second slide groove (10), so that the swing plate (7) drives the lifting plate (12) and the first material receiving box (13) on the lifting plate (12) to move up and down on the outside of the processing box (1). When the first material receiving box (13) moves upward, the elastic force of the second spring (23) drives the baffle plate (20) to block the first feed port (15) upward to prevent other large particles of rubber waste from falling directly to the ground. When the first material receiving box (13) moves upward to the discharge port (14) on one side and is connected to the second feed port (16) on the processing box (1), the large particles of rubber waste collected in the first material receiving box (13) will fall between the two crushing rollers (4) again and be crushed for the second time.
