Description

Technical Field

[0001] The invention belongs to the technical field of plastic processing and recycling devices, and in particular relates to a plastic product rough processing and recycling device. Background Art

[0002] Plastic products are a general term for household and industrial products made primarily from plastic. This includes products made using all processes, including injection molding and blister molding. Plastic is a type of synthetic polymer with plasticity. The recycling process for plastic products primarily involves collection, sorting, cleaning, crushing, recycling, production, quality inspection, and packaging. The primary processing step involves cleaning and crushing the sorted plastic sheets.

[0003] Cleaning: Waste plastics may be contaminated with oil, mud, dust and other impurities that need to be removed by cleaning. Cleaning is usually done with water or a suitable solvent, and multiple washes may be required to ensure a clean surface.

[0004] Crushing: After cleaning, the waste plastics are crushed by a crusher, cutting them into smaller particles. This helps to improve the uniformity of the recycled plastics and reduce energy consumption in the subsequent production process.

[0005] During the cleaning process of plastic products, when there is a large amount of accumulation, due to the low density of plastic products, a considerable portion of the material is always on the surface of the water body. During the horizontal rotation cleaning process, the plastic products on the surface of the water body are always unable to fully contact with the water body, thereby reducing the cleaning quality. In addition, if the plastic products are simply pressed into the water body, although they can also fully contact with the water body, the pressed baffle and the box body are always in a relatively closed state. It is generally inconvenient to remove the material from the top, and removing the material from the bottom of the box requires draining all the water first, thereby reducing work efficiency. It is also necessary to design an additional power source to reuse the water body, which increases the design cost. Summary of the Invention

[0006] The purpose of the present invention is to provide a plastic product rough processing and recovery device to solve the technical problem that when there is a large amount of plastic accumulation, due to the low density of plastic products, a considerable portion of the material is always on the surface of the water body.

The inner turntable is provided with a positioning groove connected to the center of the outer turntable, and the bottom of the positioning groove is provided with a fixing ring placed on the inner wall of the outer turntable.

[0012] Furthermore, a retaining ring is detachably installed on the top of the screw shaft, and the outer wall edge of the retaining ring is provided with a rotating groove placed on the top of the inner wall of the first box body. A through hole connected to the first slider is opened at the center of the outer turntable, and an annular protrusion adapted to the annular groove is provided on the outer wall of the through hole. One end of the outer wall of the telescopic rod is connected to the side plate on the stirring rod through a second spring.

[0013] Furthermore, the telescopic rod is connected with a slide groove along the length direction of the stirring rod, and the stirring rod is connected to the rotating shaft by plug-in installation. Conical material guide ports are opened on both sides of the top of the first box body. As the motor starts or shuts down, the movable frame drives the elastic shielding cloth around it to move outward and fit into or separate from the inner wall of the first box body.

[0014] Furthermore, the vertical center axis of the screw shaft and the vertical center axis of the rotating shaft are maintained on the same axis, and the movable frame and the stirring rod directly below are arranged in a one-to-one correspondence.

[0018] Furthermore, a conveying line placed on the bottom plate is provided between the crushing mechanism and the cleaning mechanism. The conveying line is provided on the frame and extends along a preset direction for carrying and conveying plastic products.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] (1) In the present invention, when the plastic product enters the first box through the conical discharge port, since the elastic shielding cloth is in a stationary state, the plastic product passes through the movable cavity into the interior of the first box and is in the water body. At this time, the motor starts and drives the rotating shaft and the screw shaft to rotate synchronously at the same time. During the rotation of the rotating shaft, the plastic product and the water body can be driven to rotate by the stirring rod, so that the plastic product and the water body are fully in contact, thereby improving the cleaning quality. During the rotation of the screw shaft, the movable frame on the first slider can be driven to move up and down synchronously. Since a telescopic rod is provided between the movable frame and the stirring rod, it can ensure that the stirring rod transmits power to the movable frame during the rotation process, so that it rotates together. On the other hand, the movable frame can also move up and down normally, and can serve as a guide component for the first slider to move up and down under the action of the spiral transmission, so that the first slider can drive the movable frame to move up and down normally, thereby ensuring the stability of the device.

[0021] (2) In the present invention, the annular protrusion on the outer turntable cooperates with the first slider arranged in the annular rotation, so that the movable frame connected to the outer turntable can rotate freely, and due to the centrifugal force generated during rotation, under the tensile action of the first spring, the movable frames on all sides can drive the elastic shielding cloth to move outward, and the elastic shielding cloth can fit with the inner wall of the first box when it is in the stretched state, so that the plastic products under the elastic shielding cloth are in a shielding state, so that the plastic products are in the water body, and the movable frame can rotate in water bodies of different depths during the rotation process, further making the plastic products fully contact with the water body, and when the motor stops rotating and the movable frame returns to the initial position, due to the elastic recovery action of the first spring, the elastic shielding cloth returns to a static state, and at the same time opens the movable cavity, and the plastic products return to the water body due to the action of buoyancy, and it is convenient to take out the materials, which is convenient for personnel operation and improves work efficiency.

[0022] (3) In the present invention, when the cleaned plastic products enter the second box body and enter the cutting cavity between the first cutting knives through the inclined material guide plate, the driver drives the first rotating tooth to rotate. Under the gear meshing transmission action, the first cutting knives at both ends can rotate in the opposite direction to perform shearing and crushing work. At the same time, during the rotation of the first rotating tooth, under the transmission action of the conveyor belt, the reciprocating screw can be driven to rotate, and then the second cutting knives at both ends can be moved in the opposite direction. At the same time, during the relative movement of the second cutting knife and the first cutting knife, a shearing cut can be formed, thereby performing comprehensive crushing and shearing work on the plastic products spilled into the shearing cut.

[0023] (4) A conveyor line is set up. The conveyor line can not only be used to carry and transport plastic products, but also serve as a connecting medium between the cleaning mechanism and the crushing mechanism, thereby smoothly transporting the plastic products to the crushing mechanism.

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0037] Reference Manual Figure 1 -Attached Figure 10 As shown, a plastic product rough processing and recycling device includes:

[0038] The cleaning mechanism 1 includes a motor 3 fixed to the bottom of the first housing 2. The output shaft of the motor 3 passes through the first housing 2 and extends to the rotating shaft 4 and the screw shaft 5 in sequence. The rotating shaft 4 and the screw shaft 5 are connected by a coupling 6. A stirring rod 7 is fixedly mounted on the rotating shaft 4. A first slider 8 in the shape of a ring is spirally driven on the screw shaft 5.

[0039] The outer wall edge of the first slider 8 is rotatably connected to the outer turntable 10 through the annular groove 9, and fixed blocks 11 are installed around the inner wall of the outer turntable 10. One end of the fixed block 11 is connected to the second slider 13 through the first spring 12. One end of the second slider 13 is connected to a movable frame 14 placed at the movable opening on the outer turntable 10. An elastic shielding cloth 15 is connected to the movable frame 14 by a latch locking method. A movable cavity is formed between the elastic shielding cloth 15 and the inner wall of the first box body 2, and the bottom of the movable frame 14 is connected to the stirring rod 7 through a telescopic rod 16.

[0040] Specifically, the extended end at the bottom of the second slider 13 is connected to the arc groove 18 of the inner turntable 17. The arc groove 18 is distributed around the inner turntable 17. The inner turntable 17 is provided with a positioning groove 19 connected to the center of the outer turntable 10. The bottom of the positioning groove 19 is provided with a fixing ring placed on the inner wall of the outer turntable 10.

[0041] When the plastic product enters the first box body 2 through the tapered material guide port 22, since the elastic shielding cloth 15 is in a stationary state, the plastic product passes through the movable cavity into the interior of the first box body 2 and is in the water body. At this time, the motor 3 starts and simultaneously drives the rotating shaft 4 and the screw shaft 5 to rotate synchronously. During the rotation of the rotating shaft 4, the stirring rod 7 can drive the rotation of the plastic product and the water body, so that the plastic product is in full contact with the water body, thereby improving the cleaning quality. During the rotation of the screw shaft 5, the movable frame 14 on the first slider 8 can be driven to move up and down synchronously. Since a telescopic rod 16 is provided between the movable frame 14 and the stirring rod 7, this can ensure that the stirring rod 7 transmits power to the movable frame 14 during the rotation process, so that it rotates together. On the other hand, the movable frame 14 can also move up and down normally, and can serve as a guide component for the first slider 8 to move up and down under the action of the spiral transmission, ensuring that the first slider 8 drives the movable frame 14 to move up and down normally, thereby ensuring the stability of the device.

[0042] Since the inner turntable 17 is arranged at the bottom of the inner wall of the outer turntable 10, the outer turntable 10 will drive the synchronous rotation of the inner turntable 17, and the two are in a relatively static state. When the outer turntable 10 rotates, the second slider 13 on the first spring 12 moves outward due to the stretching effect. During the outward movement of the second slider 13, since the second slider 13 is in the arc groove 18 of the inner turntable 17, the inner turntable 17 can circulate in the positioning groove 19 and can drive the synchronous movement of the second sliders 13 around it. This can ensure the synchronous movement of the second sliders 13 around it, and can simultaneously drive the outward expansion movement of the elastic shielding cloth 15 to prevent pulling damage caused by uneven force, which is not conducive to the stability of the device.

[0043] The specific working principle of the cleaning mechanism 1 is as follows:

[0044] The plastic products pass through the tapered material guide port 22 and the movable cavity into the first box body 2. After the motor 3 is started, it can drive the stirring rod 7 on the rotating shaft 4 to rotate, thereby tilting the plastic products during the stirring process. Moreover, during the rotation process, since the outer turntable 10 is movably connected to the first slider 8, the movable frame 14 on the outer turntable 10 can be driven to rotate synchronously. During the rotation process, due to the stretching effect of the first spring 12, the elastic shielding cloth 15 can be stretched and the top of the plastic product is in a relatively closed state. Moreover, the first slider 8 can drive the entire elastic shielding cloth 15 to move downward at the same time, so that the plastic products can fully contact the water body. Moreover, during the rotation process, the movable frame 14 can also play a corresponding rotating and stirring role, thereby further making the plastic products contact with the water body and improving the cleaning quality. At the same time, when the motor 3 drives the cleaning part to return to the initial position, the plastic products can re-enter the top of the first box body 2 through the movable cavity. After the top of the first box body 2 is opened, it is convenient for humans to take out materials, which speeds up work efficiency.

[0045] By extension, the movable frame 14 can be set to a conical surface inclined outward near the bottom surface of the elastic shielding cloth 15. In this way, under the action of buoyancy and the resistance direction of the elastic shielding cloth 15 itself, the cleaned plastic products can quickly pass through the movable cavity and enter the elastic shielding cloth 15. The above-mentioned conical surface setting is an obvious conventional technical means for those skilled in the art, so no detailed description of the working principle is given. Although no corresponding figure marks are made, it does not affect the effective implementation of the technical solution of the present invention.

[0046] The annular protrusion 20 on the outer turntable 10 cooperates with the first slider 8 set in the annular rotation, so that the movable frame 14 connected to the outer turntable 10 can rotate freely, and due to the centrifugal force generated during rotation, under the tensile action of the first spring 12, the movable frame 14 on all sides can drive the elastic shielding cloth 15 to move outward, and the elastic shielding cloth 15 can fit with the inner wall of the first box body 2 in the stretched state, thereby shielding the plastic products under the elastic shielding cloth 15, so that the plastic products are in the water body, and the movable frame 14 can rotate in water bodies of different depths during rotation, which can further make the plastic products fully contact with the water body, and when the motor 3 stops rotating and the movable frame 14 returns to the initial position, due to the elastic recovery action of the first spring 12, the elastic shielding cloth 15 returns to a stationary state, and the movable cavity is opened at the same time, and the plastic products return to the water body due to the action of buoyancy, and it is convenient to take out the materials, convenient for personnel operation, and improve work efficiency.

[0047] Specifically, a retaining ring is detachably installed on the top of the screw shaft 5, and a rotating groove is provided on the outer wall edge of the retaining ring and is placed on the top of the inner wall of the first box body 2. A through hole connected to the first slider 8 is opened at the center of the outer turntable 10, and an annular protrusion 20 adapted to the annular groove 9 is provided on the outer wall of the through hole. One end of the outer wall of the telescopic rod 16 is connected to the side plate on the stirring rod 7 through a second spring 21.

[0048] The telescopic rod 16 is connected with a slide groove along the length direction of the stirring rod 7. The stirring rod 7 is connected to the rotating shaft 4 by plug-in installation. Conical material guide ports 22 are provided on both sides of the top of the first box body 2. As the motor 3 is started or shut down, the movable frame 14 drives the elastic shielding cloth 15 on all sides to move outward and fit or separate from the inner wall of the first box body 2. By utilizing the elastic effect of the elastic shielding cloth 15 itself and the centrifugal force generated during rotation, the movable frame 14 can drive the synchronous movement of the elastic shielding cloth 15 during the outward movement, so that the plastic products under the elastic shielding cloth 15 can be covered and move downward synchronously with it.

[0049] The vertical center axis of the screw shaft 5 and the vertical center axis of the rotating shaft 4 are maintained on the same axis, and the movable frame 14 is arranged one-to-one with the stirring rod 7 directly below. The above-mentioned axis setting can effectively transmit the force of the motor 3 to the screw shaft 5 and the rotating shaft 4, preventing position deviation during rotation, thereby ensuring the stability of the transmission effect.

[0050] Specifically, a plastic product rough processing and recycling device also includes a crushing mechanism 23, which includes a second box body 24. A first rotating tooth 25 connected to a driver is installed on the second box body 24. The outer wall of the first rotating tooth 25 is engaged with a second rotating tooth 26 that rotates in the opposite direction. The movable shafts on the first rotating tooth 25 and the second rotating tooth 26 are fixedly connected to a cutting disk 27. The outer wall of the cutting disk 27 is connected to a first cutting knife 28 that is compatible with it. Above the first cutting knife 28, there is an inclined material guide plate 29 placed at both ends of the inner wall of the second box body 24.

[0051] The movable shaft on the first rotating tooth 25 and the central shaft fixed to the first bevel gear 30 are connected by a conveyor belt 31. The outer wall of the first bevel gear 30 is meshed with a second bevel gear 33 fixed to a reciprocating screw 32. A third slider 34 is spirally driven at both ends of the reciprocating screw 32. The first rotating tooth 25, the second rotating tooth 26, and the third slider 34 are all placed in a cover, which is connected to the outer wall of the second box 24 in a removable manner. One end of the third slider 34 is connected to an opening along the length of the inner wall of the second box 24. The third slider 34 is connected to an inclined second cutting blade 36 via a push rod 35. A shear cut is formed between the second cutting blade 36 and the first cutting blade 28, and the back of the second cutting blade 36 is provided with inclined surfaces 37 placed at both ends of the inner wall of the second box 24.

[0052] In the present invention, when the cleaned plastic products enter the second box body 24 and enter the cutting cavity between the first cutting blades 28 through the inclined guide plate 29, the driver drives the first rotating tooth 25 to rotate. Under the gear meshing transmission action, the first cutting blades 28 at both ends can be rotated in the opposite direction to perform shearing and crushing work. At the same time, during the rotation of the first rotating tooth 25, under the transmission action of the conveyor belt 31, the reciprocating screw 32 can be driven to rotate, and then the second cutting blades 36 at both ends can be moved in the opposite direction. At the same time, during the relative movement of the second cutting blade 36 and the first cutting blade 28, a shear cut can be formed, thereby performing comprehensive crushing and shearing work on the plastic products spilled into the shear cut.

[0053] In addition, a conveyor line 38 placed on the bottom plate is provided between the crushing mechanism 23 and the cleaning mechanism 1. The conveyor line 38 is arranged on the frame and extends along a preset direction to carry and convey plastic products. The essence of the conveyor line 38 is to drive the rotation of the transmission roller through the sprocket chain mechanism, thereby driving the transmission work of the conveyor line 38, and the conveyor line 38 can be adaptively replaced with an inclined track, so that the material can also slide into the crushing mechanism 23 by its own gravity.

[0054] A conveyor line 38 is provided, which can not only be used to carry and convey plastic products, but also serve as a connecting medium between the cleaning mechanism 1 and the crushing mechanism 23 , thereby smoothly conveying the plastic products to the crushing mechanism 23 .
