Description

Technical Field

[0001] The invention belongs to the technical field of waste recycling, and in particular relates to a waste recycling mechanism for plastic products and a recycling 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 from all processes such as injection molding and blister molding using plastic as the raw material. Plastic is a type of synthetic polymer material with plasticity. Together with synthetic rubber and synthetic fiber, it forms the three major synthetic materials that are indispensable in daily life. Specifically, plastic is a material with natural or synthetic resin as the main component, with various additives added. It can be molded into a certain shape under certain conditions of temperature and pressure, and maintain its shape at room temperature. In the process of producing plastic products, a large amount of waste will be generated, and in order to save costs, it is usually necessary to use recycling equipment to recycle the waste.

[0003] In the process of recycling plastic waste, in order to make the temporary space after recycling smaller, the plastic waste is first crushed, and then the crushed plastic waste is softened, so that when it is finally compressed, the gaps between the plastic waste are smaller, thereby reducing the problem of temporary large space after recycling plastic waste; However, there are the following deficiencies in the above operation process: 1. The pipe at the connection between the crushing box and the heating box is heated by the heating box, which softens the plastic waste in the crushing box, which easily causes the pipe at the connection between the crushing box and the heating box to be blocked. In addition, during the heating process of the crushed plastic waste by the heating box, the plastic waste close to the heating box is softened first, and the plastic waste in the middle of the heating box has a low softening degree, resulting in inconsistent softening degree of the plastic waste in the heating box, thus affecting the subsequent compression effect; 2. In the process of unloading the softened plastic waste after compression, the plastic waste compressed in the mold needs to be unloaded before the softened plastic waste in the heating box can be loaded, resulting in a long waiting time for unloading, thereby reducing work efficiency. To this end, we provide a waste recycling mechanism and recycling method for plastic products to solve the above problems. Summary of the invention

Through the movement of two U-shaped frames, one U-shaped frame can unload the compressed plastic waste, and the other U-shaped frame can compress the plastic waste, thereby improving the efficiency of plastic waste recycling. Through the reciprocating movement of the turning plate and the cross rod, the plastic waste can be turned over, so that it can be heated more evenly and the gaps between the compressed plastic waste can be smaller. The movement of the cross rod can clear the plastic waste in the feed pipe, thereby ensuring the smoothness of the feed pipe, solving the problems of pipe blockage at the connection between the existing crushing box and the heating box, uneven heating of the plastic waste in the heating box, and long waiting time for unloading after the compression of the plastic waste, thereby reducing work efficiency.

[0014] The present invention also includes a recycling method of a waste recycling mechanism for plastic products, characterized in that it includes the following steps: S01: First, put the plastic waste into the crushing box, then start the crushing component to complete the crushing of the plastic waste; S02: Next, the crushed plastic waste is discharged into a heating box to soften the crushed waste by heat. After softening, the solenoid valve is opened to discharge the softened plastic waste into a U-shaped frame of the receiving component; S03: Then, the hydraulic cylinder is started, so that the hydraulic cylinder drives the pressing plate to move into the U-shaped frame, thereby completing the compression of the plastic waste; S04: Finally, the U-shaped frame is controlled to move toward the lower material port so that the compressed plastic waste is transferred to the bottom of the base, thereby completing the recycling of the plastic waste.

[0015] The present invention has the following beneficial effects: 1. The present invention controls the rotation of the two first rotating shafts so that the first rotating shafts drive the crushing rollers to rotate, thereby completing the crushing of the plastic waste. The crushed plastic waste enters the interior of the heating box, and the crushed plastic waste is heated by the heating box to soften the crushed plastic waste. The softened plastic waste enters one of the U-shaped frames in the receiving assembly through the discharge pipe. At this time, one U-shaped frame containing the softened plastic waste is facing the pressure plate, and the other U-shaped frame is just located above the discharge port. Then the hydraulic cylinder is controlled The pressing plate is driven to move toward the U-shaped frame, so that the pressing plate squeezes the softened plastic waste, thereby completing the compression of the plastic waste. Finally, the U-shaped frame is controlled to move toward the discharge port, so that the U-shaped frame drives the compressed plastic waste to move toward the discharge port, thereby completing the recovery of the compressed plastic waste. At the same time, the other unloaded U-shaped frame moves to just face the pressing plate. Through the synchronous movement of the two U-shaped frames, the recovery time of the compressed plastic waste is reduced, thereby effectively improving the recovery efficiency of the plastic waste.

[0016] 2. The present invention controls the reciprocating up and down movement of the truncated cone block, so that in the process of the truncated cone block moving upward, it is pressed down by the plastic waste in the heating box, driving the flipping plate to move away from the truncated cone block, so that the flipping plate is unfolded, and the truncated cone block continues to move upward, so that the flipping plate completes the flipping of the plastic waste in the heating box, so that the plastic waste in the heating box is heated more fully, and the softening degree of the plastic waste is kept nearly consistent. The plastic waste is compressed by the pressing plate, so that the gap between the compressed plastic waste is smaller, and the volume of the compressed plastic waste is smaller. The truncated cone block moves upward. During the downward movement, the elastic force of the torque spring drives the flipping plate to shrink toward the truncated cone block, making the truncated cone block move downward more smoothly. At the same time, the truncated cone block moves back and forth up and down, and the push-pull rod drives the cross rod to move back and forth up and down synchronously, so as to avoid the heat in the heating box being transferred upward to the crushing box, so that the plastic waste in the crushing box softens and becomes sticky, making it easy to stick together, thus causing the discharge pipe to be blocked. The reciprocating up and down movement of the cross rod can clear the plastic waste in the discharge pipe, thereby ensuring the smoothness of the discharge pipe.

[0017] 3. The present invention provides power for the operation of the crushing component, the material turning and clearing component, and the receiving component by controlling a single motor power source, thereby effectively improving the full utilization of power, reducing the use of multiple power sources, and thus reducing the cost of use.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] 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.

[0037] For example, see Figure 1-15The present invention provides the following technical solutions: a waste recycling mechanism for plastic products, comprising a recycling component 1; the recycling component 1 comprises a base 101, the top of the base 101 is fixedly connected with an L-shaped support plate 102, the end of the L-shaped support plate 102 is fixedly connected with a crushing box 103, one side of the L-shaped support plate 102 is fixedly connected with an extension plate 104 located below the crushing box 103, and the side of the extension plate 104 away from the L-shaped support plate 102 is fixedly connected with a heating box 105; a feed pipe 106 is connected between the crushing box 103 and the heating box 105, and guide grooves 107 are provided on the two opposite inner sides of the feed pipe 106, and a discharge pipe 108 is connected to the bottom of the heating box 105, and an electromagnetic valve is provided on the outer peripheral side of the discharge pipe 108; a hydraulic cylinder 109 is fixedly connected to the top of the base 101, a pressing plate 110 is fixedly connected to the output end of the hydraulic cylinder 109, and a control box 111 is fixedly connected to the top of the base 101.

[0038] The pulverizing box 103 is internally rotatably matched with a pulverizing assembly 2, which includes a first rotating shaft 201 symmetrically penetrating and rotatably connected to an opposite inner side surface of the pulverizing box 103, and a pulverizing roller 202 located inside the pulverizing box 103 is fixedly connected to the peripheral side surface of the first rotating shaft 201; a material turning and dredging assembly 3 is arranged inside the heating box 105, and the material turning and dredging assembly 3 includes a truncated cone block 301 slidably arranged inside the heating box 105, and an arc groove 302 is provided on the peripheral side surface of the truncated cone block 301, and a material turning plate 303 connected by a torque spring is arranged inside the arc groove 302; a push-pull rod 304 extending to the inside of the discharge pipe 106 is fixedly connected to the top of the truncated cone block 301, and a cross rod 305 slidably matched with the guide groove 107 is fixedly connected to the peripheral side surface of the push-pull rod 304; a receiving assembly 4 is slidably matched with the top of the base 101, and the receiving assembly 4 includes two A U-shaped frame 401 (the heights of the pressing plate 110 and the U-shaped frame 401 both meet the requirements of compressing plastic waste, so that the plastic waste will not be squeezed out from the top of the U-shaped frame 401 and the pressing plate 110 during the compression process), a connecting column 402 is symmetrically fixedly connected between the two U-shaped frames 401, and an L-shaped plate 403 slidably connected to the base 101 is fixedly connected to the outer side of one of the U-shaped frames 401. The recycling component 1 also includes a first slide groove 112 opened on the top of the base 101, and the L-shaped plate 403 slides with the first slide groove 112. A discharge port 113 located outside the pressing plate 110 is symmetrically opened on the top of the base 101, and a positioning plate 114 located outside the two discharge ports 113 is symmetrically fixedly connected to the top of the base 101; a guide hopper 115 located above the crushing component 2 is fixedly connected to the inside of the crushing box 103, and a plurality of support columns 116 are fixedly connected to the bottom of the base 101.

[0039] The operation process of this embodiment is as follows: first, the plastic waste is put into the crushing box 103, and the first rotating shafts 201 are controlled to rotate so that the first rotating shafts 201 drive the crushing rollers 202 to rotate, thereby completing the crushing of the plastic waste. The crushed plastic waste enters the heating box 105, and the crushed plastic waste is heated by the heating box 105 to soften the crushed plastic waste. The softened plastic waste enters one of the U-shaped frames 401 in the receiving assembly 4 through the discharge pipe 108. At this time, one U-shaped frame 401 containing the softened plastic waste is facing the pressing plate 110, and the other U-shaped frame is just located above the discharge port 113. Then The hydraulic cylinder 109 is controlled to drive the pressing plate 110 to move toward the U-shaped frame 401, so that the pressing plate 110 squeezes the softened plastic waste, thereby completing the compression of the plastic waste. Finally, the U-shaped frame 401 is controlled to move toward the discharge port 113, so that the U-shaped frame 401 drives the compressed plastic waste to move toward the discharge port 113, thereby completing the recovery of the compressed plastic waste. At the same time, the other unloaded U-shaped frame 401 is moved to just face the pressing plate 110. Through the synchronous movement of the two U-shaped frames 401, the recovery time of the compressed plastic waste is reduced, thereby effectively improving the recovery efficiency of the plastic waste. When the crushed plastic waste enters the heating box 105, the truncated cone block 301 is synchronously controlled to reciprocate up and down, so that when the truncated cone block 301 moves upward, it is pressed down by the plastic waste in the heating box 105, driving the flipping plate 303 to move away from the truncated cone block 301, so that the flipping plate 303 is unfolded, and the truncated cone block 301 continues to move upward, so that the flipping plate 303 completes the flipping of the plastic waste in the heating box 105, so that the plastic waste in the heating box 105 is heated more fully, thereby keeping the softening degree of the plastic waste nearly consistent, and the plastic waste is compressed by the pressing plate 110, so that the gap between the compressed plastic waste is smaller, thereby making the volume of the compressed plastic waste smaller During the downward movement of the truncated cone block 301, the elastic force of the torque spring drives the flipping plate 303 to shrink in the direction close to the truncated cone block 301, so that the truncated cone block 301 can move downward more smoothly. At the same time, the truncated cone block 301 can reciprocate up and down by synchronously driving the push-pull rod 304 to drive the cross rod 305 to reciprocate up and down, so as to avoid the heat in the heating box 105 from being transferred upward to the crushing box 103, so that the plastic waste in the crushing box 103 becomes sticky after being softened, so that it is easy to stick together, thereby causing the discharge pipe 106 to be blocked. The reciprocating up and down movement of the cross rod 305 can realize the dredging of the plastic waste in the discharge pipe 106, so as to ensure the smoothness of the discharge pipe 106.

[0040] For example 2, please refer to Figure 1-15, the second embodiment is improved on the basis of the first embodiment as follows: the crushing assembly 2 also includes an L-shaped rod 203 fixedly connected to an outer side of the crushing box 103, the end of the L-shaped rod 203 is fixedly connected to a motor 204, the output end of the motor 204 is fixedly connected to the end of one of the first rotating shafts 201, the peripheral side surfaces of the two first rotating shafts 201 are fixedly connected with meshing spur gears 205, and the end of the other first rotating shaft 201 is fixedly connected with a worm 206, and the material turning and dredging assembly 3 also includes a first vertical plate 306 fixedly connected to the top of the base 101, and a moving rod 307 extending to the inside of the heating box 105 is slidably connected to one side of the first vertical plate 306, and a support rod 308 is ball-hinged between the moving rod 307 and the truncated cone block 301, and the end of the moving rod 307 away from the support rod 308 is fixedly connected to a plate 309, and the plate 309 and the first vertical plate 306 are fixedly connected. A first spring 310 mounted on the moving rod 307 is fixedly connected therebetween. The receiving assembly 4 also includes a first sliding rod 404 fixedly connected to an outer side surface of another U-shaped frame 401. The first sliding rod 404 slidably cooperates with one of the positioning plates 114. A baffle 405 is fixedly connected to the end of the first sliding rod 404. A second spring 406 mounted on the first sliding rod 404 is fixedly connected between the baffle 405 and one of the positioning plates 114; a first tooth plate 407 is fixedly connected to an adjacent outer side surface of one of the U-shaped frames 401, and a cylindrical hole 408 is symmetrically opened on one side surface of the first tooth plate 407. A second sliding rod 409 is slidably connected to the inner circumferential side surface of the cylindrical hole 408, and a second tooth plate 410 is fixedly connected between the two second sliding rods 409. A return spring 411 mounted on the second sliding rod 409 is fixedly connected between the inner bottom of the cylindrical hole 408 and the second tooth plate 410.

[0041] The operation process of this embodiment is as follows: by starting the motor 204, the motor 204 drives one of the first rotating shafts 201 to rotate, thereby driving one of the spur gears 205 to rotate, thereby driving another spur gear 205 meshing therewith to rotate, and the other spur gear 205 drives another first rotating shaft 205 to rotate, thereby providing power for the rotation of the two first rotating shafts 205; The support plate 309 is pulled away from the heating box 105, and the truncated block 301 is driven to move downward through the moving rod 307 and the support rod 308 (the first spring 310 is stretched at this time), and then the support plate 309 is free from force, so that the support plate 309 is driven to move toward the heating box 105 under the elastic force of the first spring 310, and the truncated block 301 is driven to move upward through the moving rod 307 and the support rod 308, providing power for the truncated block 301 to move up and down; By controlling the first tooth plate 407 to move toward the L-shaped support plate 102, the U-shaped frame 401 close to the L-shaped support plate 102 moves to abut against the adjacent positioning plate 114 (the second spring 406 is compressed at this time). At this time, the U-shaped frame 401 close to the L-shaped support plate 102 is just facing the discharge port 113, and the other U-shaped frame 401 is facing the pressing plate 110, so that the U-shaped frame 401 facing the pressing plate 110 performs a compression operation on the plastic waste, so that the plastic waste compressed in the U-shaped frame 401 facing the discharge port 113 falls from the discharge port 113 and is then recovered; After the first tooth plate 407 is free from stress, the elastic force of the second spring 406 drives the U-shaped frame 401 away from the L-shaped support plate 102 to move in the direction of the discharge port 113 away from the L-shaped support plate 102.
