Description

Technical Field

[0001] The present invention relates to the technical field of plastic waste recycling, and in particular to a plastic waste recycling device and a use method thereof. Background Art

[0002] Plastic products are a general term for daily and industrial products made of plastic as the main raw material, including products made of plastic through all processes such as injection molding and blister molding. Plastic is a widely used and highly recyclable item; the waste generated during plastic production and the plastic products after use have very good recycling value. However, the waste from plastic production will be stained with a lot of stains after being piled up. The traditional plastic waste recycling device breaks the plastic waste into suitable sizes and collects them. It also needs to take out the fragments for cleaning and recycling, which is troublesome and labor-consuming. Now there are patent documents to improve this.

[0003] For example, Chinese patent CN219311751U, a plastic product waste recycling device, includes: a feed port, a box, a crushing mechanism, a slide rail, a drawer, a water inlet, a cleaning mechanism, a water outlet, and a material taking door. A feed port is provided on the top of the box; the crushing mechanism is installed inside the box, just below the feed port; two slide rails are relatively arranged and fixedly installed on the two side walls of the box just below the crushing mechanism; the drawer passes through the front of the box and is slidably installed on the two slide rails; the bottom of the drawer is hollowed out and provided with a screening net; a cleaning mechanism is installed inside the box, just below the screening net; the water inlet is installed on the outer wall of the box below one of the slide rails; the water outlet is provided at the bottom of the box, and a cover is provided at the outer end of the water outlet; the material taking door is installed on the outer wall of the box, facing the cleaning mechanism. The cleaning mechanism includes a second drive structure, a rotating shaft, and multiple cleaning brushes; it can directly remove the fragments after they are crushed and cleaned, reducing trouble and saving manpower.

[0004] Although the equipment in the above documents can directly clean the debris and improve the cleaning efficiency, it still has obvious defects in actual use, such as:

[0005] The existing cleaning of plastic fragments needs to be done separately, but the wet fragments need to be dried after cleaning to facilitate subsequent bagging and storage. However, the fragments cleaned by the equipment still need to be unloaded and transported by the staff, which does not bring convenience and efficiency to the staff. At the same time, the weight increases due to the increase of moisture, making it difficult to carry;

[0016] The present invention also discloses a method for using the plastic waste recycling device, which specifically comprises the following steps:

[0017] S1. Before use, first fill the cleaning pool with water and submerge the scooping frame, and connect the water pump to the water source. After starting the water pump, the spray pipe sprays water from right to left, and the water inside the cleaning pool is slowly discharged outward through the pipe to always keep the water level below the cleaning pool. Then put the plastic waste into the hopper. Since the discharge port and the side sealing vertical plate fit the plastic, it cannot leak out. After it is full, start the cylinder to push the top plate seat and the hopper to the top. After the hopper rises to the top, it separates from the side sealing vertical plate, and the plastic falls from the discharge port to the inside of the crushing frame. At this time, the motor starts and drives the two first rotating rods and the crushing roller to rotate through the gear plate to break the plastic waste into small pieces. At the same time, the rotation of the first rotating rod will drive the second rotating rod to rotate through the pulley and the belt. After the waste inside the crushing frame is discharged, the cylinder drives the hopper to drop to the bottom again for feeding;

[0018] S2. After the crushing roller rotates to break the plastic waste, the plastic fragments fall into the inside of the cleaning pool, and the water flow sprayed from the spray pipe will wash the fragments and use the impact force of the water to push the fragments to slowly move to the left. After the fragments move to the left, the cylinder is started again. The cylinder pushes the top plate seat to rise. The rise of the top plate seat will pull the scooping frame to rise. At the same time, the top plate seat will first drive the curved rod to be pulled up and down from the inside of the retraction cylinder. After the scooping frame rises, the fragments on the water surface will be scooped inside, and the water filter inclined plate will filter out the water. When the scooping frame and the water filter inclined plate rise to be flush with the top of the cleaning pool, the scooping frame will continue to Continuous rise will make the bent rod pull the retraction cylinder and the inclined plate to rise together. When the scooping frame rises to half of the main body and the same height as the receiving frame, the inclined plate will contact the pressure-bearing rod, and the inclined plate will squeeze the pressure-bearing rod to make the receiving frame move left under the limit of the horizontal tie rod and the blocking slide. Since the two water filtering inclined plates at the bottom of the scooping frame are conical, there will be no resistance when the receiving frame moves. When the bottom of the scooping frame is completely located at the upper part of the receiving frame, the receiving frame moves to the bottom of the scooping frame. At this time, after the cylinder moves upward for the last short distance, the conical vertical plate will support the convex block at the limit of the vertical sliding guide frame. The locking pin is pushed out from the inside of the pin groove under the downward position, and the conical vertical plate also squeezes the two sliding sleeve plates to move the two side round rods away from each other under the limit of the horizontal sliding rod. At this time, the two water filtering inclined plates are no longer squeezed and automatically open downward, and then the internal debris falls into the inside of the receiving frame for storage, and the blocking slide blocks its bottom to prevent the debris from leaking out. When these processes are completed, the material hopper will rise again to feed the inside of the crushing frame. After the debris inside the scooping frame is unloaded, the cylinder will drive the scooping frame to descend through the top plate seat. At the same time, the retraction cylinder will drive the inclined plate to descend, and the inclined plate After the panel stops squeezing the pressure rod, the cross tie rod docks with the feeding trough due to the elasticity of the first spring due to reset, and the conical vertical plate no longer presses the convex block after the scooping frame descends. At this time, the two side abutting round rods and the sliding sleeve plate move toward each other under the thrust of the second spring. The movement of the side abutting round rods will squeeze the two water filter inclined plates to flip and close to close the bottom of the scooping frame. After the sliding sleeve plate is reset, the locking pin will be reinserted into the inner side of the pin slot to fix the side abutting round rod. After the scooping frame completely enters the cleaning pool, the cone formed when the two water filter inclined plates close together will discharge the debris to both sides, and the debris will float on the water again.

[0019] S3. After the receiving frame is docked with the feeding trough, the fragments inside the receiving frame fall into the drying box. Due to the transmission of the pulley and the belt, the second rotating rod drives the auger blades to rotate. At the same time, the drying box starts to heat the inside. The rotation of the auger blades pushes the fragments forward, and the drain port drains the water from the fragments. The moving fragments will be dried by the drying box and discharged from the front of the drying box. Beneficial Effects

[0020] The present invention provides a plastic waste recycling device and a method for using the same. Compared with the existing technology, the device has the following beneficial effects:

[0021] (1) The plastic waste recycling device and its use method use a cleaning and drying mechanism and a feeding and transporting mechanism in combination. The arrangement of the two mechanisms can utilize the lifting and lowering of the cylinder and the linkage between the structures to sequentially complete the feeding of the crushing frame, the salvaging and transporting of the fragments after cleaning, and finally the drying and dehydration of the fragments using a drying box. The whole process does not require excessive operation by the staff, and can achieve continuous processing of plastic waste, thereby improving efficiency and satisfying current use.

[0022] (2) The plastic waste recycling device and its use method are characterized in that a water filter inclined plate is installed at the bottom of the scooping frame, and a side support round bar and a convex block are installed at the rear of the scooping frame by using a vertical sliding guide frame and a horizontal sliding rod, and the scooping frame is used in combination with a conical vertical plate. The arrangement of these structures can use the water filter inclined plate to scoop up the debris after the scooping frame rises, and can use the conical vertical plate to squeeze the convex block after rising to the top to push the two side support round bars to separate and open the water filter inclined plate, so that the debris inside can be poured into the inside of the receiving frame. After the scooping frame descends, the second spring can be used to drive the side support round bars to move toward each other, close the two water filter inclined plates, and facilitate the subsequent scooping of the debris. At the same time, the docking of the locking pin and the pin groove can ensure the stability of the side support round bar.

[0023] (3) The plastic waste recycling device and its use method are characterized by installing an inclined plate on one side of the retracting cylinder, and using it in combination with a second rotating rod and a horizontal tie rod. The arrangement of these structures can squeeze the pressure-bearing rod after the inclined plate rises, thereby pushing the material receiving frame to move to the bottom of the material scooping frame to receive the material. After the inclined plate falls, the elastic force of the first spring can be used to reset the material receiving frame and dock it with the feeding trough, so that the wet fragments can enter the drying box to complete the feeding. The entire process does not require staff to operate, thereby reducing the workload.

[0024] (4) The plastic waste recycling device and its use method are used in conjunction with a hopper by installing a side sealing vertical plate at the bottom of the crushing frame. The arrangement of these structures can place plastic waste inside the hopper. After the cylinder drives the hopper to rise, the waste can be put into the crushing frame through the discharge port, thereby completing the loading and facilitating the use of the staff.

[0040] The present invention also discloses a method for using the plastic waste recycling device, which specifically comprises the following steps:

[0041] S1. Before use, first fill the cleaning pool 102 with water and submerge the scoop frame 209, and connect the water pump 109 to the water source. After starting the water pump 109, the spray pipe 110 sprays water from right to left, and the water inside the cleaning pool 102 is slowly discharged outward through the pipe to keep the water level below the cleaning pool 102. Then, the plastic waste is put into the hopper 203. Since the discharge port 204 and the side sealing vertical plate 108 fit the plastic and cannot leak out, after it is filled, start the cylinder 201 to push the top plate seat 202 and the hopper 203 to rise. To the top, the hopper 203 rises to the top and separates from the side sealing vertical plate 108, and the plastic falls from the discharge port 204 to the inside of the crushing frame 103. At this time, the motor 107 starts to drive the two first rotating rods 104 and the crushing roller 105 to rotate through the gear plate 106 to break the plastic waste into small pieces. At the same time, the rotation of the first rotating rod 104 drives the second rotating rod 112 to rotate through the pulley 113 and the belt 114. After the waste inside the crushing frame 103 is discharged, the cylinder 201 drives the hopper 203 to descend to the bottom again for feeding;

[0042] S2. After the crushing roller 105 rotates to break the plastic waste, the plastic fragments fall into the interior of the cleaning tank 102, and the water flow sprayed from the spray pipe 110 will rinse the fragments and use the impact force of the water to push the fragments to slowly move to the left. After the fragments move to the left, the cylinder 201 is started again, and the cylinder 201 pushes the top plate seat 202 to rise. The rise of the top plate seat 202 will pull the scooping frame 209 to rise. At the same time, the top plate seat 202 will also first drive the bending rod 205 to be pulled up and down from the inside of the retraction cylinder 206. After the scooping frame 209 rises, the fragments on the water surface will be scooped inside, and the water filtering inclined plate 210 will filter out the water. When the scooping frame 209 and the water filtering inclined plate 210 rise to be flush with the top of the cleaning tank 102, the scooping frame 209 continues to rise. The rod 205 pulls the retraction cylinder 206 and the inclined plate 208 to rise together. After the scooping frame 209 rises to half of the main body and the same height as the material receiving frame 119, the inclined plate 208 will contact the pressure-bearing rod 122, and the inclined plate 208 will squeeze the pressure-bearing rod 122 to allow the material receiving frame 119 to move left under the limit of the horizontal tie rod 120 and the blocking slide plate 118. Since the two water filtering inclined plates 210 at the bottom of the scooping frame 209 are conical, there will be no conflict when the material receiving frame 119 moves. When the bottom of the scooping frame 209 is completely located at the upper part of the material receiving frame 119, the material receiving frame 119 moves to the bottom of the scooping frame 209. At this time, after the cylinder 201 moves upward for the last short distance, the conical vertical plate 123 will support the convex block 219 in the vertical sliding guide frame 21 6, the locking pin 220 is pushed out from the inside of the pin slot 221, and at the same time, the conical vertical plate 123 also squeezes the two sliding sleeve plates 213 to allow the two side round rods 214 to move back to each other under the limit of the horizontal sliding rod 212. At this time, the two water filtering inclined plates 210 are no longer squeezed and automatically open downward, and then the internal debris falls into the inside of the receiving frame 119 for storage, and the blocking slide plate 118 blocks its bottom to prevent the debris from leaking. When these processes are completed, the hopper 203 will rise again to feed the inside of the crushing frame 103. After the debris inside the scooping frame 209 is unloaded, the cylinder 201 will drive the scooping frame 209 to descend through the top plate seat 202. At the same time, the retraction cylinder 206 will drive the inclined plate 208 to descend. After the pressure rod 122 is not squeezed, the cross tie rod 120 is reset and docked with the feeding trough 117 under the elasticity of the first spring 121, and the conical vertical plate 123 no longer presses the convex block 219 after the scooping frame 209 descends. At this time, the two side abutting round rods 214 and the sliding sleeve plate 213 move toward each other under the thrust of the second spring 215. The movement of the side abutting round rods 214 will squeeze the two water filtering inclined plates 210 to flip and close to close the bottom of the scooping frame 209. After the sliding sleeve plate 213 is reset, the locking pin 220 will be reinserted into the inner side of the pin slot 221 to fix the side abutting round rod 214. After the scooping frame 209 completely enters the cleaning pool 102, the cone formed when the two water filtering inclined plates 210 are closed will discharge the debris to both sides, and the debris will float on the water again.

[0043] S3. After the receiving frame 119 is docked with the feeding trough 117, the fragments inside the receiving frame 119 fall into the drying box 111. Due to the transmission of the pulley 113 and the belt 114, the second rotating rod 112 will drive the auger blade 115 to rotate. At the same time, the drying box 111 starts to heat the inside. The rotation of the auger blade 115 will push the fragments forward, and the drain port 116 will drain the water from the fragments. The moving fragments will be dried by the drying box 111 and discharged from the front of the drying box 111.

2. A method for using a plastic waste recycling device, characterized in that: The specific steps include: S1. Before use, first fill the cleaning pool (102) with water and submerge the scoop frame (209), and connect the water pump (109) to the water source. After starting the water pump (109), the spray pipe (110) sprays water from right to left, and the water inside the cleaning pool (102) is slowly discharged outward through the pipe to keep the water level below the cleaning pool (102). Then, the plastic waste is put into the hopper (203). Since the discharge port (204) and the side sealing vertical plate (108) fit the plastic, it cannot leak out. After the hopper is filled, the cylinder (201) is started to push the top plate seat (202) and the hopper (203) to rise to the top. The material hopper (203) rises to the top and is separated from the side sealing vertical plate (108), and the plastic falls from the discharge port (204) into the crushing frame (103). At this time, the motor (107) starts to drive the two first rotating rods (104) and the crushing roller (105) to rotate through the gear plate (106) to break the plastic waste into small pieces. At the same time, the rotation of the first rotating rod (104) drives the second rotating rod (112) to rotate through the pulley (113) and the belt (114). After the waste inside the crushing frame (103) is discharged, the cylinder (201) drives the material hopper (203) to descend to the bottom again for feeding; S2, after the crushing roller (105) rotates to crush the plastic waste, the plastic pieces fall into the interior of the cleaning pool (102), and the water flow sprayed from the spray pipe (110) will wash the pieces and use the impact force of the water to push the pieces to slowly move to the left. After the pieces move to the left, the cylinder (201) is started again, and the cylinder (201) pushes the top plate seat (202) to rise. The rise of the top plate seat (202) will pull the scooping frame (209) to rise. At the same time, the top plate seat (202) will also first drive the bent rod (205) to be pulled up and down from the inside of the retracting cylinder (206). After the scooping frame (209) rises, the pieces on the water surface will be trapped inside, and the water filtering inclined plate (210) will filter out the water. After the scooping frame (209) and the water filtering inclined plate (210) rise to When flush with the top of the cleaning pool (102), the scooping frame (209) continues to rise, causing the curved rod (205) to pull the retracting cylinder (206) and the inclined plate (208) to rise together. When the scooping frame (209) rises to half of the main body and the same height as the material receiving frame (119), the inclined plate (208) will contact the pressure rod (122), and the inclined plate (208) will squeeze the pressure rod (122) to allow the material receiving frame (119) to move left under the limit of the horizontal tie rod (120) and the blocking slide (118). Since the two water filtering inclined plates (210) at the bottom of the scooping frame (209) are conical, there will be no conflict when the material receiving frame (119) moves. When the bottom of the scooping frame (209) is completely located at the material receiving frame (119), When the material receiving frame (119) moves to the bottom of the material scooping frame (209), the cylinder (201) moves upward for the last short distance, and the conical vertical plate (123) pushes against the convex block (219) under the limit of the vertical slide guide frame (216) to push the locking pin (220) out from the inside of the pin slot (221). At the same time, the conical vertical plate (123) also squeezes the two sliding sleeve plates (213) under the limit of the horizontal slide rod (212) to move the two side abutting round rods (214) away from each other. At this time, the two water filter inclined plates (210) are no longer squeezed and automatically open downward, and then the internal debris falls into the inside of the material receiving frame (119) for storage, and the blocking slide plate (118) blocks the bottom of the material receiving frame to prevent the debris from leaking out. These processes At the same time, the material hopper (203) will rise again to feed the material into the crushing frame (103). After the debris in the scooping frame (209) is unloaded, the cylinder (201) will drive the scooping frame (209) to descend through the top plate seat (202). At the same time, the retraction cylinder (206) will drive the inclined plate (208) to descend. After the inclined plate (208) does not squeeze the pressure-bearing rod (122), the cross tie rod (120) will be reset and docked with the feeding trough (117) under the elasticity of the first spring (121). After the scooping frame (209) descends, the conical vertical plate (123) no longer presses the convex block (219). At this time, the two side abutting round rods (214) and the sliding sleeve plate (213) move toward each other under the thrust of the second spring (215).The movement of the side-retaining round rod (214) will squeeze the two water filter inclined plates (210) to flip and close together to close the bottom of the scooping frame (209). After the sliding plate (213) is reset, the locking pin (220) will be reinserted into the inner side of the pin slot (221) to fix the side-retaining round rod (214). After the scooping frame (209) completely enters the cleaning pool (102), the cone formed when the two water filter inclined plates (210) are closed will discharge the debris to both sides, and the debris will float on the water surface again. S3, after the receiving frame (119) is docked with the feeding trough (117), the fragments inside the receiving frame (119) fall into the interior of the drying box (111). Due to the transmission of the pulley (113) and the belt (114), the second rotating rod (112) drives the auger blade (115) to rotate. At the same time, the drying box (111) starts to heat the interior. The rotation of the auger blade (115) pushes the fragments forward. The drain port (116) drains the water from the fragments. The moving fragments are dried by the drying box (111) and discharged from the front of the drying box (111).
