Description

Technical Field

[0001] This invention belongs to the field of recycling device technology, specifically a waste plastic recycling device for pet plastic product processing. Background Technology

[0002] With the increasing number of pet owners, the pet toy market has excellent prospects. However, because pets are quite destructive to plastic toys, recycling waste plastics from pet toy manufacturing is an important environmental action to reduce costs and increase efficiency. This effectively reduces plastic pollution and provides resources for reuse. Collected plastic waste typically needs to be sent to specialized equipment for crushing or shredding.

[0003] An existing waste plastic recycling device for plastic processing, with publication number CN120363371A, uses a multi-stage shredder to cut the input plastic products, resulting in more complete and thorough cutting and crushing of waste plastic, avoiding the situation where large pieces of plastic are not completely cut. However, in order to ensure cutting accuracy, the structure of the lower cutting blades is more fragile than that of the upper coarse cutting blades. This means that if the plastic clumps together and accumulates in the lower cutting area due to adhesion, the blades in this area may wear out faster due to the greater hardness of the plastic blocks, thus affecting their service life. Therefore, improvements are needed. Summary of the Invention

[0004] To address the problem that existing technologies easily damage the lower cutting tools during plastic processing, the technical solution adopted in this invention is: a waste plastic recycling device for pet plastic product processing, comprising a processing cylinder and a recycling tank, wherein the recycling tank is located on the right side of the processing cylinder, and a support base is provided at the bottom of the processing cylinder. The processing cylinder includes a housing shell, a pretreatment chamber, and a crushing component: The pretreatment chamber is located on the upper part of the inner wall of the receiving cylinder, and the top of the crushing component extends into the interior of the pretreatment chamber. The rotary motor on the upper part of the inner wall of the receiving cylinder drives the pretreatment chamber to rotate through the contact roller shaft.

[0005] Furthermore, the pretreatment chamber includes: A receiving top cylinder is provided, wherein a guide ring rail is fitted onto the outer surface of the receiving top cylinder, and a cover opening groove is provided on the top of the receiving top cylinder; The container top cover has an outer surface that is inserted into the top of the receiving top cylinder through an opening groove. Rotary caps are evenly arranged on the upper part of the container top cover. By rotating the rotary caps, the slot of the container top cover is opened, and the plastic is put into the pretreatment chamber. The pressure-bearing balls are evenly distributed at the bottom of the receiving cylinder.

[0006] Furthermore, the processing cylinder also includes an insertable guide shaft, an embedded retaining plate, and a buffer base pad. The outer surface of the rotary motor is inserted into the inner wall of the receiving cylinder through a clamping plate, and the outer surface of the rotary motor shaft is inserted into the axis of the inserted guide shaft. The axis of the inner cavity of the contact roller shaft is slidably connected to the outer surface of the inserted guide shaft, and the outer surface of the contact roller shaft is rolledly connected to the inner wall of the guide ring rail. The contact roller shaft can slide vertically along the outer surface of the inserted guide shaft. The embedded card plate is inserted into the inner wall of the receiving cylinder shell; The bottom of the buffer pad is inserted into the bottom of the inner wall of the receiving cylinder. The buffer pad is used to support the fixed inner plate at the bottom and reduce the load on the embedded plate.

[0007] Furthermore, the crushing component includes a fixed inner disc, a bidirectional motor, an extended rotating shaft, and a flow guiding component: The outer surface of the fixed inner disk is inserted into the outer surface of the embedded card plate through a groove, and the upper surface of the fixed inner disk is uniformly provided with thrust balls, and the outer surface of the thrust balls and the outer surface of the pressure balls are pressed against each other. Both sides of the inner wall of the fixed inner plate are connected to the outer surface of the bidirectional motor by fixing rods; The top of the extended shaft extends into the interior of the receiving top cylinder, and coarse cutting blades are evenly inserted into the outer surface of the extended shaft. The bottom end of the extended shaft is inserted into the top end of the bidirectional motor shaft.

[0008] Furthermore, the drainage component includes a rotating base plate, an inner rotating guide tube, a drainage air duct, and an external connector: The outer surface of the rotating base plate is rotatably connected to the bottom of the inner cavity of the top cylinder. The inner cavity of the rotating base plate is evenly provided with a semi-sealed inner cover through a through groove. The opening of the semi-sealed inner cover is offset from the opening of the inner rotating guide cylinder. When the two openings are connected, the plastic inside the top cylinder can be guided to be discharged downwards. The top of the inner rotating guide tube is rotatably connected to the inner cavity of the rotating base plate through a through groove. The inner wall of the air duct is sleeved with the outer surface of the inner rotating guide tube, and the air inlet of the air duct passes through the inner cavity of the inner rotating guide tube. The inner rotating guide tube enables the semi-sealed inner cover to have the ability to adsorb and contain plastic debris inside the top tube. The top of the external connector is sleeved with the bottom of the internal rotating guide tube.

[0009] Furthermore, the crushing component also includes a shaft chuck and a control motor: The outer surface of the shaft chuck is engaged with the shaft center of the inner wall of the fixed inner plate. The outer surface of the air duct is inserted into the through-hole of the shaft chuck. The outer surface of the control motor shaft is inserted into the lower surface of the shaft chuck. A rubber sleeve is inserted into the outer surface of the control motor shaft. The outer surface of the rubber sleeve is rotatably connected to the outer surface of the air duct. When the control motor drives the air duct to rotate, it will control the inner rotating guide tube to rotate, thereby connecting the opening of the semi-sealed inner cover with the opening of the inner rotating guide tube.

[0010] Furthermore, this includes refined components and cleaners: The refining component is located at the center of the bottom of the inner wall of the receiving cylinder, and the sweeper is located at the bottom of the refining component.

[0011] Furthermore, the refined components include a housing top cover, a fine blade rotating column, and a guide rail: The bottom of the storage top cover is inserted with a secondary processing cylinder, the bottom of the secondary processing cylinder is inserted with the axis at the bottom of the inner cavity of the receiving cylinder shell, and the outer surface of the cleaner is inserted with the axis at the bottom of the inner wall of the secondary processing cylinder. The top end of the fine blade rotating column is inserted into the bottom end of the bidirectional motor rotating shaft, and rotating scrapers are evenly arranged on the upper part of the outer surface of the fine blade rotating column, and the outer surface of the rotating scrapers is in contact with the inner wall of the storage top cover. The top of the outer guide rail is inserted into the inner cavity of the auxiliary processing cylinder through a slot, and the bottom of the outer guide rail extends into the inside of the recycling tank. The sweeper pushes the plastic debris accumulated at the bottom of the auxiliary processing cylinder into the outer guide rail by rotating the upper sweeping rod.

[0012] The beneficial effects of this invention are as follows: 1. During the rough processing of plastic products placed inside the receiving top cylinder by the coarse cutting blade, the receiving top cylinder rotates and periodically contacts and squeezes the thrust balls at the bottom, thereby causing the plastic products inside to shake vertically. This causes the plastic accumulated at the bottom of the inner wall of the receiving top cylinder to jump to the height of the coarse cutting blade, and then be repeatedly cut by the coarse cutting blade. The coarse cutting blade can also further break up and crush the clumps of plastic particles, thus ensuring that very few large debris remains after coarse cutting, thereby reducing the workload of the refining components.

[0013] 2. When the top cylinder rotates, its rotation direction is opposite to that of the coarse cutting blade. Therefore, the actual relative rotation speed of the coarse cutting blade will increase, resulting in a greater cutting force on the plastic and improving crushing efficiency. Since the semi-enclosed inner cover opening at the bottom of the top cylinder is completely offset from the top opening of the inner rotating guide cylinder when processing the plastic inside, the plastic particles inside the top cylinder cannot be discharged. This ensures that the plastic particles fed into the top cylinder can be fully and effectively cut, avoiding the problem of insufficient cutting of plastic due to excessive plastic feeding and relatively short cutting time of the coarse cutting blade.

[0014] 3. When discharging plastic particles, the air duct will enable the inner guide tube to adsorb the plastic particles inside the top cylinder. Therefore, the plastic particles accumulated in the dead corner at the bottom of the top cylinder can be discharged into the interior of the refining component under the guidance of the airflow. This avoids the problem of plastic particles blocking the inner guide tube due to gravity, and also reduces the residue of plastic particles inside the top cylinder, thus keeping the inside of the top cylinder clean.

[0015] 4. The plastic particles discharged into the refining component will slide down the inner wall of the secondary processing cylinder. An expanding receiving top cover collects the plastic particles, so the plastic particles with strong impact discharged from the external end will not splash outside the refining component, thereby further realizing the refining and crushing process. Since the rotating scraper will rotate with the shaft of the bidirectional motor, the rotating scraper can scrape off the plastic particles attached to the outer surface of the receiving top cover, thereby avoiding the accumulation of plastic particles inside the receiving top cover, which would prevent the secondary processing cylinder from processing the fed plastic in time and cause the problem of unbalance between discharge and supply.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: a waste plastic recycling device for pet plastic product processing, comprising a processing cylinder 1 and a recycling tank 4, wherein the recycling tank 4 is located on the right side of the processing cylinder 1, and a support base 3 is provided at the bottom of the processing cylinder 1. The processing cylinder 1 includes a housing shell 11, a pretreatment chamber 5, and a crushing component 6. The pretreatment chamber 5 is located on the upper part of the inner wall of the housing shell 11, and the top of the crushing component 6 extends into the interior of the pretreatment chamber 5. The rotary motor 14 on the upper part of the inner wall of the housing shell 11 drives the pretreatment chamber 5 to rotate through the contact roller shaft 16.

[0020] Pretreatment chamber 5 includes: The top cylinder 51 is accommodating, and a guide ring rail 52 is fitted onto the outer surface of the top cylinder 51. The top of the top cylinder 51 is provided with a cover opening groove. The container top cover 54 has its outer surface inserted into the top of the receiving top cylinder 51 through an opening groove. Rotary caps 55 are evenly arranged on the upper part of the container top cover 54. By rotating the rotary caps 55, the slot of the container top cover 54 is opened, and the plastic is put into the pretreatment chamber 5. The pressure-bearing balls 53 are evenly distributed at the bottom of the receiving top cylinder 51.

[0021] The processing cylinder 1 also includes an insertion guide shaft 15, an embedded clamping plate 12, and a buffer base pad 13. The outer surface of the rotary motor 14 is inserted into the inner wall of the receiving cylinder 11 via a clamping plate, and the outer surface of the rotating shaft of the rotary motor 14 is inserted into the axis of the insertion guide shaft 15. The axis of the inner cavity of the contact roller shaft 16 is slidably connected to the outer surface of the insertion guide shaft 15, and the outer surface of the contact roller shaft 16 is rolledly connected to the inner wall of the guide ring rail 52. The contact roller shaft 16 can slide vertically along the outer surface of the insertion guide shaft 15. The embedded card plate 12 is inserted into the inner wall of the receiving cylinder shell 11; The bottom of the buffer pad 13 is inserted into the bottom of the inner wall of the receiving cylinder 11. The buffer pad 13 is used to support the fixed inner plate 61 at the bottom and reduce the load on the embedded card plate 12.

[0022] The crushing component 6 includes a fixed inner disc 61, a bidirectional motor 63, an extended rotating shaft 64, and a drainage component 7. The outer surface of the fixed inner plate 61 is inserted into the outer surface of the embedded card plate 12 through a groove, and the upper surface of the fixed inner plate 61 is uniformly provided with thrust balls 62, and the outer surface of the thrust balls 62 and the outer surface of the pressure balls 53 are pressed against each other. Both sides of the inner wall of the fixed inner plate 61 are connected to the outer surface of the bidirectional motor 63 by fixing rods; The top of the extended shaft 64 extends into the interior of the receiving top cylinder 51, and coarse cutting blades 65 are evenly inserted into the outer surface of the extended shaft 64. The bottom end of the extended shaft 64 is inserted into the top end of the shaft of the bidirectional motor 63.

[0023] Open the top rotating cover 55 and put the waste plastic toy into the receiving top cylinder 51. Then, the bidirectional motor 63 drives the top coarse cutting blade 65 to rotate through the extended rotating shaft 64 to perform coarse cutting processing on the plastic products inside the receiving top cylinder 51.

[0024] When the coarse cutting blade 65 rotates, the rotary motors 14 located on both sides of the receiving cylinder shell 11 rotate the contact roller shaft 16, thereby driving the receiving top cylinder 51 to rotate in the opposite direction to the coarse cutting blade 65. When the receiving top cylinder 51 rotates, the pressure ball 53 at its bottom will sweep across the thrust ball 62 on the upper surface of the fixed inner plate 61. Under the action of its own weight and the thrust of the thrust ball 62, the receiving top cylinder 51 reciprocates along the vertical direction, thereby causing the plastic products inside the receiving top cylinder 51 to shake continuously in the vertical direction, increasing the contact probability between the plastic and the coarse cutting blade 65, so that the coarse cutting blade 65 can cut the plastic products accumulated at the bottom of the receiving top cylinder 51 and break up the clumps of plastic products.

[0025] Example 2, please refer to Figures 1-8The present invention provides a technical solution: based on embodiment 1, the drainage component 7 includes a rotating base plate 71, an inner rotating guide tube 73, a drainage air duct 74, and an external connection end 75. The outer surface of the rotating base plate 71 is rotatably connected to the bottom of the inner cavity of the receiving top cylinder 51. The inner cavity of the rotating base plate 71 is evenly provided with a semi-sealed inner cover 72 through a through groove. The opening of the semi-sealed inner cover 72 is offset from the opening of the inner rotating guide cylinder 73. When the two openings are connected, the plastic inside the receiving top cylinder 51 can be guided to be discharged downwards. The top of the inner rotating guide tube 73 is rotatably connected to the inner cavity of the rotating base plate 71 through the through groove. The inner wall of the air duct 74 is sleeved with the outer surface of the inner rotating guide tube 73, and the air inlet of the air duct 74 passes through the inner cavity of the inner rotating guide tube 73. The inner rotating guide tube 73 enables the semi-sealed inner cover 72 to have the ability to adsorb and contain plastic debris inside the top tube 51. The top of the external end 75 is sleeved with the bottom of the internal rotating guide tube 73.

[0026] The crushing component 6 also includes a shaft chuck 66 and a control motor 67. The outer surface of the shaft chuck 66 is engaged with the shaft center of the inner wall of the fixed inner plate 61. The outer surface of the air duct 74 is inserted into the through port of the shaft chuck 66. The outer surface of the control motor 67 shaft is inserted into the lower surface of the shaft chuck 66. A rubber sleeve is inserted into the outer surface of the control motor 67 shaft. The outer surface of the rubber sleeve is rotatably connected to the outer surface of the air duct 74. When the control motor 67 drives the air duct 74 to rotate, it will control the inner rotating guide tube 73 to rotate, thereby connecting the opening of the semi-sealed inner cover 72 with the opening of the inner rotating guide tube 73.

[0027] Includes refinement component 8 and sweeper 2: The refining component 8 is located at the axis at the bottom of the inner wall of the receiving cylinder 11, and the sweeper 2 is located at the bottom of the refining component 8.

[0028] The refined component 8 includes a top cover 82, a fine blade rotating column 84, and a guide rail 85. A secondary processing cylinder 81 is inserted into the bottom of the storage top cover 82. The bottom of the secondary processing cylinder 81 is inserted into the axis at the bottom of the inner cavity of the receiving cylinder shell 11, and the outer surface of the cleaner 2 is inserted into the axis at the bottom of the inner wall of the secondary processing cylinder 81. The top end of the fine blade rotating column 84 is inserted into the bottom end of the rotating shaft of the bidirectional motor 63, and rotating scrapers 83 are evenly arranged on the upper part of the outer surface of the fine blade rotating column 84, and the outer surface of the rotating scrapers 83 is in contact with the inner wall of the storage top cover 82. The top of the guide rail 85 is inserted into the inner cavity of the auxiliary processing cylinder 81 through a slot, and the bottom of the guide rail 85 extends into the inside of the recycling tank 4. The sweeper 2 pushes the plastic debris accumulated at the bottom of the auxiliary processing cylinder 81 into the guide rail 85 by rotating the upper sweeping rod.

[0029] After the plastic inside the top cylinder 51 is roughly processed, it will be discharged into the lower refining component 8 through the drainage component 7. At this time, the control motor 67 will drive the drainage air duct 74 and the inner rotating guide cylinder 73 to rotate along the groove of the rotating base plate 71, so that the top opening of the inner rotating guide cylinder 73 is connected with the opening of the semi-sealed inner cover 72. Then the drainage air duct 74 draws air, so that the shredded plastic particles inside the top cylinder 51 enter the inner rotating guide cylinder 73 and slide down along the outer end 75 into the receiving top cover 82. After the discharge is completed, the control motor 67 rotates the inner rotating guide cylinder 73 again, so that the top opening of the inner rotating guide cylinder 73 is completely misaligned with the opening of the semi-sealed inner cover 72, thereby sealing the bottom opening of the top cylinder 51.

[0030] The bidirectional motor 63 drives the fine blade rotating column 84 and the rotating scraper 83 to rotate via the bottom rotating shaft. The rotating scraper 83 scrapes off the plastic particles attached to the inner wall of the storage top cover 82. When the plastic particles slide down the inner wall of the secondary processing cylinder 81, they are further crushed and refined by the rotating blades on the outer surface of the fine blade rotating column 84, and then accumulate at the bottom of the inner wall of the secondary processing cylinder 81.

[0031] The sweeper 2 periodically rotates its sweeping bar, pushing the plastic particles accumulated at the bottom of the inner wall of the secondary processing cylinder 81 into the guide rail 85. Under the action of gravity, the plastic particles slide down the guide rail 85 into the recycling tank 4, thus completing the collection process. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
