Description

Technical Field

[0001] The invention relates to the technical field of plastic product crushing, in particular to a plastic product crushing device. Background Art

[0002] The density of PP plastic is relatively small, about 0.9-0.91g / cm 3 PP is one of the lightest plastics known so far, and its density is less than that of water under standard atmospheric pressure. This gives it a great advantage in manufacturing some products that require weight. For example, when making toys, using PP plastic can reduce the overall weight of the toy. PP plastic has high tensile strength and impact resistance, making the toy less likely to break when impacted.

[0003] According to a Chinese patent with publication number "CN119078032A", a garbage recycling crushing device includes a plastic garbage crushing chamber, and the bottom end of the plastic garbage crushing chamber is connected to the top end of the screening chamber, and the bottom end of the screening chamber is provided with a discharge port. During use, the present invention uses a screening plate to screen the crushed plastic garbage particles, so that the plastic particles processed by the equipment can meet the size requirements, and the flexible scraper assembly circulates to push the plastic particles that do not meet the size to the inside of the transmission port, and the centrifugal force generated by the transmission pump will cooperate with the reflux pipe and the transmission pipe to re-suck the unqualified plastic garbage particles after screening into the inside of the plastic garbage crushing chamber for re-crushing. Compared with traditional devices, it is difficult to meet all the subsequent reuse requirements after plastic garbage processing, which leads to insufficient recycling of plastic garbage and the need for manual screening and other operations.

[0004] The above patent uses a crushing blade to crush the plastic during use. The iron nails used to assemble the PP plastic will turn into iron filings after being crushed. When the PP plastic is crushed, the PP plastic is prone to generate static electricity during the crushing process. The static electricity will cause the plastic fragments and the iron filings to be adsorbed together and difficult to separate, which will lead to an increase in the impurity rate when the plastic is recycled. Therefore, a plastic product crushing device is proposed to solve the above-mentioned problems. Summary of the invention

[0017] The present invention adopts the above technical solution to bring the following beneficial effects:

[0018] 1. The invention sets a separation mechanism to separate plastic and iron filings in water by utilizing the density difference between plastic, iron filings and water. The surface humidity of plastic fragments in contact with water will increase. In an environment with high humidity, the charge generated by friction is more easily absorbed and neutralized by water molecules, thereby reducing the generation of static electricity by increasing humidity, and separating the plastic and iron filings adsorbed together by static electricity. The plastic fragments and iron filings in the pool are completely immersed in water by means of an electric telescopic rod, a cross bar, a first horizontal axis and a pressure plate. At the same time, the stirring rod is driven to rotate by means of a straight slide groove, a first slider and a second horizontal axis. The plastic fragments and iron filings adsorbed together by static electricity and suspended in the water are stirred by the rotation of the stirring rod, thereby promoting the contact between the two and water. By further increasing the surface humidity of the plastic fragments, the plastic fragments and iron filings are separated more thoroughly, thereby reducing the impurity rate during plastic recycling.

[0019] 2. The invention provides a separation mechanism, and drives the movable frame to move downward to the inside of the second water tank through the bent rod. At this time, the liquid level heights in the pool and the first water tank will be higher than the liquid level height in the second water tank. A siphon effect is generated through the liquid level difference, so that the plastic fragments floating on the water surface in the pool flow into the second water tank together with the water through the vertical groove and the first water tank, and the plastic fragments flowing into the movable frame are filtered out through the first filter box. Therefore, the plastic fragments that can be continuously filtered by the water flow are improved, and the filtration efficiency is improved. The iron filings and water at the bottom of the pool are discharged by providing a first water pump and a suction hopper, and the propeller blades are driven to rotate by the first slider, cable, wire drum, and vertical axis. The fluidity of the water flow at the bottom of the pool is increased by the rotation of the propeller blades. The water flow with good fluidity can cover every corner of the pool and reduce cleaning dead corners. The water flow with good fluidity can suspend the sediment, which is convenient for cleaning the iron filings at the bottom of the pool through the suction hopper.

[0020] 3. The invention sets a circulation mechanism to separate iron filings from water through a suction hopper, a first water pump, a first water return pipe and a second filter box, sprays water on the bottom of the filter through the second water pump and the second water return pipe, clears the iron filings blocked in the filter, maintains the smooth flow of water and iron filings, thereby improving the filtering efficiency, making it easier to intercept impurities such as iron filings, and thus improving the filtering effect of the second filter box on iron filings.

[0021] 4. The invention is configured such that the horizontal bar moves up and down to drive the vertical bar to move up and down, and the vertical bar moves up and down to drive the second slider to move left and right through the inclined slide, and the second slider drives the bracket and two hoses to swing left and right. The swinging hoses and nozzles increase the uniformity of spraying on the surface of the crushing roller, thereby increasing the surface humidity of the crushing roller. Plastics will generate heat during the crushing process, causing the plastic to soften or even melt, and thus easily adhere to the crushing roller. Water spraying can effectively reduce the roller surface temperature and reduce the adhesion of plastics due to heat. Plastics are prone to static electricity during the crushing process, and static electricity will attract plastic particles to adhere to the roller surface. Water spraying can reduce the generation of static electricity and reduce the adsorption of plastic particles, thereby preventing the crushed material fragments from adhering to the crushing roller, thereby improving the crushing efficiency of the crushing roller for plastics.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The separation mechanism 4 includes an electric telescopic rod 401, a cross bar 402, a plurality of first cross shafts 403, a pressure plate 404, a first torsion spring 405, and two sets of limiting grooves 406;

[0035] The top of the electric telescopic rod 401 is fixedly connected to the front outer wall of the crusher 3 through a fixed plate, the cross bar 402 is fixedly connected to the bottom end of the electric telescopic rod 401, the front end of the first transverse axis 402 is rotatably connected to the back of the cross bar 403 through a bearing, the pressing plate 404 is fixedly connected to the first transverse axis 403, the first torsion spring 405 is sleeved on the first transverse axis 403, and the pressing plate 404 is driven to return to its original position by the rebound force. The front and rear ends of the first torsion spring 405 are respectively fixedly connected to the cross bar 402 and the pressing plate 404, and the limiting groove 406 is provided on the back inner wall of the pool 1 to limit the rotation angle of the pressing plate 404. The rear end of the pressing plate 404 is slidably connected to the limiting groove 406. The crushed PP plastic and iron filings will fall into the pool 1. Because the density of PP plastic is less than that of water, it will float on the water surface, while the density of iron filings is greater than that of water and will sink to the bottom of the pool 1. The plastic and iron filings adsorbed together by static electricity will be suspended in the water.

[0036] A straight slide groove 407 is provided on the inner wall of the back of the pool 1, and a first slider 408 is slidably connected inside the straight slide groove 407. A first movable plate 409 is fixedly connected to the top of the first slider 408. The top of the first movable plate 409 contacts the pressing plate 404. The pressing plate 404 contacts the first movable plate 409 during the downward movement, and drives the first slider 408, the second horizontal axis 4010, and the stirring rod 4011 to move downward. The front side of the first slider 408 is rotatably connected to the second horizontal axis 4010 through a bearing, and the second horizontal axis 4010 is fixedly connected to the stirring rod 4011. The stirring rod 4011 is used to stir the plastic and iron filings suspended in the water that are adsorbed together due to static electricity, thereby promoting the contact between the two and the water, and promoting the elimination of static electricity by further increasing the humidity. A gear 4012 is fixedly connected to the middle of the second horizontal axis 4010, and a rack 4013 is fixedly connected to the left inner wall of the straight slide groove 407. The rack 4013 is meshed with the gear 4012. During the downward movement of the second horizontal axis 4010, the stirring rod 4011 is driven to rotate by the mutual cooperation between the gear 4012 and the rack 4013.

[0037] Working principle: First, put PP plastic and the iron nails used to assemble PP plastic into the crusher 3 for crushing. The crushed plastic fragments and iron filings will fall into the water pool 1. Since the density of PP plastic is less than that of water, it will float on the water surface, while the density of iron filings is greater than that of water and will sink to the bottom of the water pool 1. The plastic and iron filings adsorbed together by static electricity will be suspended in the water, and the cross bar 402 will be driven up and down by the electric telescopic rod 401. During the downward movement of the cross bar 402, the first horizontal axis 403 and the pressing plate 404 will be driven downward. During the descent of the pressing plate 404, it will be separated from the top limiting groove 406, and will rebound to a horizontal state under the action of the rebound force of the first torsion spring 405. During the downward movement of several pressing plates 404 in a horizontal state, they will be spliced ​​together and move downward together to completely immerse the plastic fragments and iron filings in the water pool 1 in water, increase the surface humidity of the plastic fragments by contact with water, and increase the humidity by increasing the humidity The pressing plate 404 can eliminate static electricity and separate the plastic and iron filings adsorbed together due to static electricity. As the pressing plate 404 continues to move downward, it will contact the bottom limiting groove 406 and flip over. At this time, the spliced ​​pressing plates 404 will disintegrate, and the plastic fragments under the pressing plate 404 will float back to the water surface under the buoyancy of the water, thereby completing the separation of the PP plastic and the iron filings. During the downward movement of the pressing plate 404, it will contact the first movable plate 409 and drive the first slider 408, the second horizontal axis 4010, and the stirring rod 4011 to move downward. During the downward movement of the second horizontal axis 4010, the stirring rod 4011 is driven to rotate through the mutual cooperation between the gear 4012 and the rack 4013. The plastic and iron filings adsorbed together due to static electricity suspended in the water are stirred through the rotation of the stirring rod 4011, which promotes the contact between the two and the water. By further increasing the surface humidity of the plastic fragments, the effect of eliminating static electricity is increased.

When the movable frame 504 moves downward to the inside of the second water tank 503, the liquid levels in the pool 1 and the first water tank 501 will be higher than the liquid level in the second water tank 503. As a result, the water in the first water tank 501 will flow into the second water tank 503, and the plastic fragments floating on the water surface in the pool 1 will flow into the second water tank 503 together with the water through the vertical groove 502 and the first water tank 501.

[0042] Working principle: When the cross bar 402 moves downward, it drives the movable frame 504 to move downward through the curved rod 506. When the movable frame 504 moves downward to the inside of the second water tank 503, the liquid level in the pool 1 and the first water tank 501 will be higher than the liquid level in the second water tank 503, so that the water in the first water tank 501 will flow into the second water tank 503, and the plastic fragments floating on the water surface in the pool 1 will flow into the second water tank 503 through the vertical groove 502 and the first water tank 501 together with the water, and pass through the first The filter box 505 filters the plastic fragments and water that flow into the movable frame 504, and the iron filings and water at the bottom of the pool 1 are discharged by setting a first water pump and a suction hopper 5014. When the first slider 408 moves upward, it pulls the cable 5012, and the wire drum 5010 rotates during the unwinding process, driving the vertical shaft 507 and the propeller blades 508 to rotate. The rotation of the propeller blades 508 increases the fluidity of the water flow at the bottom of the pool 1, thereby improving the cleaning effect of the first water pump and the suction hopper 5014 on iron filings.
