Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic screening and processing technology, specifically to a plastic particle washing device. Background Technology
[0002] Plastic processing, also known as plastic molding processing, is a general term for various processes that transform synthetic resins or plastics into plastic products. It is a major production sector in the plastics industry. Plastic processing generally includes plastic batching, molding, machining, joining, finishing and assembly. The latter four processes are carried out after the plastic has been molded into products or semi-finished products, and are also known as secondary plastic processing.
[0003] An existing plastic particle cleaning device, such as the invention patent document with authorization announcement number "CN220716988U" and patent name "An EPP Particle Cleaning Device", discloses a plastic particle cleaning device, including a container, a fixed frame fixedly connected to the top of the inner wall of the container, a first rotating disk movably sleeved in the inner cavity of the fixed frame, a shaft propeller fixedly connected to the bottom of the first rotating disk, a top cover fixedly installed on the top of the container, a motor fixedly installed on the top of the top cover, the output shaft of the motor passing through the top cover and docking with the first rotating disk, and a water inlet pipe fixedly connected to the side wall of the container.
[0004] The aforementioned patent document describes a method of using a motor to drive a stirring blade to rotate, thereby agitating the plastic particles and cleaning liquid to achieve the cleaning purpose. However, the stirring blade mainly acts on the particles in the middle area of the container, while the particles near the inner wall and corners are difficult to be effectively tumbled, resulting in cleaning dead zones and uneven cleaning. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plastic particle cleaning device. This device addresses the problem mentioned in the background section where existing plastic particle cleaning devices use a motor to drive agitator blades to rotate, thereby agitating the plastic particles and cleaning liquid to achieve the cleaning purpose. However, the agitator blades mainly act on particles in the central area of the container, while particles near the inner wall and corners are difficult to be effectively tumbled, resulting in cleaning dead zones and uneven cleaning.
[0006] A plastic particle cleaning device includes a base, a support seat slidably mounted vertically on the base, a first rotating shaft rotatably mounted on the support seat, a cleaning tank fixedly mounted on the first rotating shaft, a door opening on the side wall of the cleaning tank, a hollow second rotating shaft rotatably mounted on the support seat, the second rotating shaft slidingly passing through the cleaning tank and extending into the cleaning tank, a plurality of cleaning rollers fixedly mounted on the second rotating shaft, and the plurality of cleaning rollers located inside the cleaning tank, a first driving assembly for driving the support seat to move vertically on the base, a second driving assembly for driving the first rotating shaft to rotate on the driving assembly, and a collection rack for collecting plastic particles fixedly mounted on the base, the collection rack being located below the door.
[0007] Working principle:
[0008] First, the first drive assembly drives the support base and all its components to slide back and forth vertically. This movement causes the cleaning tank and the plastic particles and cleaning liquid inside to shake up and down, achieving initial agitation and pre-cleaning of the materials. At the same time, the second drive assembly drives the first rotating shaft to rotate, thereby causing the entire cleaning tank to rotate around its axis. The rotation of the cleaning tank further intensifies the irregular movement of the materials inside the tank. While the cleaning tank is rotating, the second rotating shaft running through the tank and the multiple cleaning rollers fixed on it also rotate. The cleaning rollers rotate inside the tank, directly agitating, rubbing, and brushing the plastic particles in their trajectory. After cleaning is completed, the first drive assembly is stopped, the door is opened, and the cleaned plastic particles are discharged from the door under the action of gravity and fall into the fixed collection rack located directly below, completing the collection.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] The first and second drive components enable the support to sway vertically, the cleaning tank to rotate, and the cleaning roller to rotate simultaneously. These actions work together on the plastic particles inside the tank, resulting in the particles not only being thrown and tumbled as a whole, but also being locally mechanically cleaned by the cleaning roller, thus improving the uniformity of particle cleaning.

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0016] Example:
[0017] like Figure 1 As shown, a plastic particle cleaning device includes a base 1, on which a support seat 2 is vertically slidably mounted. Guide rods 9 are fixed on both sides of the top of the base 1, and the support seat 2 is slidably mounted on the two guide rods 9 on both sides of the bottom. The guide rods 9 provide guidance and support for the vertical reciprocating motion of the support seat 2, which ensures that the support seat 2 and all its components maintain a stable motion trajectory during the lifting process and prevents deviation or jamming.
[0018] like Figure 1 and Figure 2 As shown, a first rotating shaft 3 is rotatably mounted on the support base 2, and a cleaning tub 4 is fixedly mounted on the first rotating shaft 3. A door 5 is opened on the side wall of the cleaning tub 4. A hollow second rotating shaft 6 is rotatably mounted on the support base 2, and the second rotating shaft 6 slides through the cleaning tub 4 and extends into the cleaning tub 4. A plurality of cleaning rollers 7 are fixedly mounted on the second rotating shaft 6, and the plurality of cleaning rollers 7 are located inside the cleaning tub 4. A gear ring 18 is fixedly mounted at one end of the cleaning tub 4. A first gear 19 is rotatably mounted on the support base 2 and meshes with the gear ring 18. A second gear 20 is fixedly mounted on the second rotating shaft 6 and meshes with the first gear 19. The second rotating shaft 6 is rotatably sealed with a bellows 21 at its end. The second rotating shaft 6 has several water outlet holes 22. The cleaning tank 4 is used to hold plastic particles and cleaning liquid. When the cleaning tank 4 rotates, the gear ring 18 on it will drive the first gear 19 meshing with it to rotate. The first gear 19 will then drive the second gear 20 meshing with it to rotate, thereby ultimately driving the second rotating shaft 6 and the cleaning roller 7 to rotate toward the cleaning tank 4. The hollow second rotating shaft 6 serves as a water supply channel. The cleaning liquid is introduced into the continuously rotating second rotating shaft 6 through the bellows 21 and then evenly sprayed onto the plastic particles in the cleaning tank 4 through the multiple water outlet holes 22 on the shaft wall. The bellows 21 allows the second rotating shaft 6 to maintain a sealed connection with the external water source when rotating and moving vertically to a certain extent.
[0019] like Figure 1As shown, the base 1 is provided with a first driving assembly for driving the support 2 to move vertically. The first driving assembly includes a motor 10, a drive shaft 11, a cam 12, and a roller 13. The motor 10 is fixed on the base 1. The drive shaft 11 is rotatably mounted on the base 1 and one end of the drive shaft 11 is fixedly connected to the output end of the motor 10. The cam 12 is fixed on the drive shaft 11. The roller 13 is rotatably mounted on the bottom of the support 2 and abuts against the cam 12. When the motor 10 is started, it drives the drive shaft 11 and the cam 12 on it to rotate. During the rotation, the profile of the cam 12 will periodically push up the roller 13 that is in contact with it, thereby pushing the entire support 2 to move upward along the guide rod 9. When the protruding part of the cam 12 rotates open, the support 2 falls under the action of gravity. This cycle is repeated to realize the continuous vertical reciprocating swaying of the support 2 and the cleaning tub 4.
[0020] like Figure 1 As shown, the drive assembly is equipped with a second drive assembly for driving the first rotating shaft 3 to rotate. The second drive assembly includes a driven shaft 14, a spline sleeve 15, two first bevel gears 16, and two second bevel gears 17. The driven shaft 14 is rotatably mounted on the base 1, and one end of the driven shaft 14 has a spline shaft structure. The spline sleeve 15 is mounted on the driven shaft 14. The two first bevel gears 16 are respectively fixed on the driven shaft 14 and the spline sleeve 15. The two second bevel gears 17 are respectively fixed on the drive shaft 11 and the first rotating shaft 3, and the two second bevel gears 17 mesh with the two first bevel gears 16 respectively. The motor 10 drives the drive shaft 11. The second bevel gear 17 drives the first bevel gear 16, which meshes with it and is fixed to the driven shaft 14. Thus, the first bevel gear 16 drives the driven shaft 14 to rotate, which in turn drives another first bevel gear 16, which is fixed to the spline shaft end of the driven shaft 14, and drives the second bevel gear 17, which meshes with it and is fixed to the spline sleeve 15. The spline sleeve 15 can be displaced on the driven shaft 14 when the support 2 moves vertically.
[0021] like Figure 1 and Figure 3 As shown, a collection rack 8 for collecting plastic particles is fixed on the base 1 and is located below the door 5. The collection rack 8 is located between the washing tank 4 and the support base 2. A filter screen 23 for collecting plastic particles is slidably installed on the collection rack 8. After washing, the door 5 on the side wall of the washing tank 4 is opened, and the washed plastic particles and sewage are discharged together and fall into the collection rack 8 directly below. The mixture of particles and water falls onto the filter screen 23. The water is separated through the filter screen 23, while the plastic particles are trapped on the screen surface.
[0022] Working principle:
[0023] First, add the plastic particles to be cleaned into the cleaning tank 4 and close the door 5. Start the motor 10, and its output shaft drives the drive shaft 11 and the cam 12 fixed on it to rotate. During the rotation, the cam 12 periodically pushes up the roller 13 at the bottom of the support seat 2, thereby pushing the entire support seat 2 and all its components to move upward along the guide rod 9. When the protruding part of the cam 12 turns open, the support seat 2 falls back under the action of gravity. This cycle realizes the continuous vertical reciprocating shaking of the cleaning tank 4, and initially turns the material in the tank.
[0024] Meanwhile, the rotational power of the drive shaft 11 is transmitted to the first bevel gear 16 meshing with it through the second bevel gear 17, thereby driving the driven shaft 14 to rotate. The power of the driven shaft 14 is transmitted to the spline sleeve 15 through another set of first bevel gears 16 and second bevel gears 17, thereby driving the first rotating shaft 3 and the cleaning tank 4 to rotate around their axis. The rotation of the cleaning tank 4 drives the gear ring 18 on it to move together. The gear ring 18 drives the first gear 19 meshing with it to rotate. The first gear 19 then drives the second gear 20 fixed on the second rotating shaft 6, ultimately causing the second rotating shaft 6 and its multiple cleaning rollers 7 to rotate inside the cleaning tank 4. During this process, the external cleaning liquid is pumped into the hollow second rotating shaft 6 through the bellows 21 and sprayed evenly into the tank through the water outlet 22 on it. Thus, the vertical shaking, self-rotation, and rotation of the cleaning tank 4 and the rotation of the internal cleaning rollers 7 perform the cleaning operation on the plastic particles.
[0025] After cleaning, open the chamber door 5, and the mixture is discharged under gravity and falls into the collection rack 8 directly below. The liquid is separated through the sliding filter screen 23, while the clean plastic particles are trapped on the surface of the filter screen 23.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
