Description

Technical Field

[0001] This invention relates to the field of plastic recycling technology, specifically to a waste recycling device and process for the production of plastic parts for mops. Background Technology

[0002] A mop is a common cleaning tool, usually consisting of a handle, connecting parts, and a cleaning head. The cleaning head absorbs water and detergent or comes into direct contact with the ground, and dust and stains are removed by dragging it manually. It is widely used for cleaning various indoor floors in homes, offices, and other places. The plastic parts of the mop mainly play a key role in fixing, connecting, protecting, and assisting in cleaning. The invention disclosed in publication number CN116118051B is a crushing device for recycling plastic raw materials, including an upper box. Two crushing rollers are symmetrically arranged inside the upper box. Under the action of a drive component, the two crushing rollers begin to rotate, and simultaneously, an extrusion seat begins to extrude the plastic raw material. The crushed plastic falls into the lower box under the action of a guide table, where it undergoes secondary crushing by a fine crushing component, and plastic particles meeting size requirements are screened out. The coordinated operation of these mechanisms effectively avoids the phenomenon of flying debris during the crushing process, ensuring efficient plastic processing. In the injection molding production of mop plastic parts, unusable or non-standard plastic parts are first collected and then uniformly crushed and recycled. During crushing and recycling, the crushing blades, after prolonged use, require periodic disassembly, grinding, and spacing adjustment. During assembly or adjustment, the moving and fixed blades need to be repeatedly hammered and adjusted, which is time-consuming and labor-intensive. Summary of the Invention

The length of the grinding strip and the reciprocating mounting plate is less than the length of the reciprocating groove, and the length of the grinding strip is greater than the length of the moving blade.

[0010] Preferably, a reciprocating control cavity is formed on the side of the tilting support plate near the reciprocating groove. A reciprocating control frame is horizontally movable within the reciprocating control cavity via a guide rod. A traction groove is formed on one side of the reciprocating control cavity connecting to the reciprocating groove. A reciprocating control plate is located on one side of the reciprocating control frame near the traction groove. One side of the reciprocating control plate is connected to the upper end of the reciprocating mounting plate. An impeller groove is formed at the lower end of the tilting support plate within the reciprocating control cavity. A synchronous shaft is rotatably inserted between the impeller groove and the reciprocating control cavity. A crescent gear and a paving impeller are respectively located within the reciprocating control cavity and the impeller groove on the synchronous shaft. The crescent gear is positioned... At the center of the reciprocating control frame, several reciprocating control teeth are provided on both sides of the reciprocating control frame near the crescent gear. One side of the crescent gear's teeth is connected to one side of the reciprocating control frame's teeth. A mounting strip is horizontally provided at the lower end of the movable slide. One side of several second arc-shaped piston rods is connected to the mounting strip. A first valve groove is provided in the mounting strip. A first check valve is inserted into the first valve groove. A blow control groove and a first transfer groove are provided on both sides of the first valve groove, passing through the crescent gear and the second arc-shaped piston rod respectively. The blow control groove is provided on the side away from the first check valve, passing through the flip support plate.

[0011] Preferably, a pressure relief and diversion groove is horizontally formed at the upper end of the movable slide near the constraint opening. A second transfer groove is formed on one side of the pressure relief and diversion groove, which is connected to the first diversion groove. A second valve groove is formed in the second transfer groove, and a second one-way valve is provided in the second valve groove. Several air blowing and dispersing holes are formed in the pressure relief and diversion groove, which are inclined towards the fixed knife.

[0012] Preferably, the positioning plate is located on one side of the crushing control main shaft that passes through the plastic recycling machine. The plastic recycling machine is provided with a positioning mounting bracket on the side near the positioning plate. A positioning telescopic rod is movably inserted into one side of the positioning mounting bracket. A conical positioning block is located on one side of the positioning telescopic rod. The positioning plate has three positioning holes, which are respectively set to correspond to three moving blades. One side of the conical positioning block is inserted into one of the positioning holes.

[0013] A process for recycling waste materials from the production of mop plastic parts includes the following steps: Step 1: When waste plastic parts from mops need to be recycled, they are poured into the plastic recycling machine from the top. At this time, the crushing control spindle inside the plastic recycling machine is driven to rotate by the transmission belt. The crushing control spindle controls the moving blades to cooperate with the fixed blades set on the tilting support plate to crush the plastic parts poured into the plastic recycling machine. Plastic particles that do not meet the required particle size are continuously disturbed in the plastic recycling machine under the action of the moving blades and the bottom screen until plastic particles that meet the required particle size are discharged from the holes of the bottom screen. Step 2: When the moving blade wears down as it rotates and crushes, the external air groove connected to the second flow channel sends in high-pressure airflow. At this time, the high-pressure airflow pushes several second arc-shaped piston rods to move, and then flips the support plate upward along the flip axis, flipping the grinding strip below the flip support plate to an inclined state. At this time, the inclination angle of the grinding strip is the same as the inclination angle of the moving blade. Step 3: The main shaft of the crushing control rotates one of the moving blades to a horizontal position. Then, the positioning telescopic rod pushes the conical positioning block into the positioning hole to assist in positioning the horizontal posture of the moving blade, so that the grinding bar and the cutting edge of the moving blade correspond. Step 4: Push the moving slide towards the crushing control shaft using the push control cylinder. At this time, the moving slide is stably guided by the support guide tube. When the side of the moving constraint nut contacts the plastic recycling machine, the grinding strip and the moving blade just come into contact. Then, high-pressure airflow is continuously sent into the second diversion groove. At this time, the high-pressure airflow breaks through the one-way blockage of the first one-way valve and enters the impeller groove from the blowing control groove. It blows the rotating impeller and then controls the semi-circular gear to rotate synchronously. When the semi-circular gear rotates, the reciprocating control frame moves back and forth in the reciprocating control cavity through the meshing control of the reciprocating control teeth. Then, the reciprocating mounting plate drives the grinding strip to move back and forth at the cutting edge of the moving blade to achieve the grinding effect. Step 5: When high-pressure airflow is introduced into the first diversion groove, the tilting support plate can be pushed back to the horizontal position. The moving slide supports the tilting support plate from the bottom. The first arc-shaped piston rod, in conjunction with the high-pressure gas in the first diversion groove, presses the tilting support plate downward to fit against the moving slide, ensuring stability when the fixed blade participates in crushing. When the air pressure in the first diversion groove continues to increase and breaks through the one-way blockage of the second one-way valve, the high-pressure airflow enters the pressure relief diversion groove from the second transfer groove, and then blows onto the upper surface of the fixed blade from several air-blowing dispersion holes. Under the guiding effect of the fixed blade surface, the fixed blade and the area above it are cooled by air blowing, reducing the overheating and adhesion of plastic between the moving blade and the fixed blade.

[0014] Compared with the prior art, the beneficial effects of the present invention are: An adjustable adjustment component is installed inside the plastic recycling machine. The fixed blade is then fixed on the tilting support plate of the adjustment component. When the tilting support plate is adjusted to a horizontal position, the fit clearance between the moving blade and the fixed blade can be ensured. When the tilting support plate is tilted and adjusted, the blade edge of the moving blade can be ground with the help of the blade edge treatment component. This reduces the frequency of disassembly and maintenance of the moving blade and the fixed blade and the adjustment problems during reinstallation, thereby improving the convenience of operation and use.

A positioning telescopic rod is movably inserted into one side of the mounting bracket 38. A conical positioning block 41 is located on one side of the positioning telescopic rod. Three positioning holes 40 are opened on the positioning plate 39. The three positioning holes 40 are respectively set to correspond to the three moving blades 3. One side of the conical positioning block 41 is inserted into one of the positioning holes 40. The movable slide 5 can move horizontally inside the plastic recycling machine 1. The crushing control main shaft 2 is driven by a motor or a single-cylinder diesel engine through pulleys and belts. When the conical positioning block 41 is inserted into the positioning hole 40, one of the moving blades 3 is in a horizontal position.

[0020] An adjustment assembly is set up to adjust the positional relationship between the movable slide 5 and the flip support plate 9. The adjustment assembly is located inside the plastic recycling machine 1 near the crushing control main shaft 2. The adjustment assembly includes the movable slide 5 and the flip support plate 9. One side of the flip support plate 9 is movably inserted into the movable slide 5. The upper end of the flip support plate 9 near the crushing control main shaft 2 is fixed with a fixed blade 10 by bolts. The center of the movable slide 5 away from the crushing control main shaft 2 is provided with a push control cylinder 6. One side of the push control cylinder 6 is connected to the plastic recycling machine 1. Both sides of the movable slide 5 away from the crushing control main shaft 2 are provided with horizontal support guide tubes 15. The two support guide tubes 15 are respectively movably inserted through the plastic recycling machine 1. The side of the support guide tube 15 inserted through the plastic recycling machine 1 is provided with a scale screw 16. The scale screw 16 is fitted with a movable constraint nut 17. The movable constraint nut 17 can be adjusted on the scale screw 16 to achieve the maximum movement limit when the push control cylinder 6 pushes the movable slide 5.

[0021] A rotation control groove is provided inside the movable slide 5. A constraint opening 8 is provided through the movable slide 5 on one side of the rotation control groove. A flipping shaft 7 is horizontally provided inside the rotation control groove. One side of the flipping support plate 9 passes through the constraint opening 8 and is inserted into the rotation control groove. The flipping support plate 9 is movably sleeved with the flipping shaft 7 on one side of the rotation control groove. The fixed blade 10 is horizontally provided at the upper end of the flipping support plate 9 that extends out of the movable slide 5. When the flipping support plate 9 is in a horizontal state, the fixed blade 10 is correspondingly set with the moving blade 3. An arc-shaped baffle is provided on the side of the flipping support plate 9 located inside the rotation control groove to prevent plastic particles in the plastic recycling machine 1 from entering the rotation control groove.

[0022] A horizontal air-receiving mounting plate 11 is provided on the side of the rotary control groove away from the constraint opening 8. Several arc-shaped piston tubes 12 are provided at both the upper and lower ends of the air-receiving mounting plate 11. Several first arc-shaped piston rods 13 are provided at the upper end of the rotary control groove, and several second arc-shaped piston rods 14 are provided at the lower end of the rotary control groove. The first and second arc-shaped piston rods 13 and 14 are respectively movably inserted into the arc-shaped piston tubes 12, and the virtual axes of the arc-shaped piston tubes 12, the first arc-shaped piston rods 13, and the second arc-shaped piston rods 14 are all coaxial with the flip axis 7. An external air-receiving groove 18 is provided at the center of each of the two support guide tubes 15, through which a graduated screw 16 passes. The upper and lower ends of the 1 are respectively horizontally provided with a first diversion groove and a second diversion groove. Two external air grooves 18 are respectively connected to the first diversion groove and the second diversion groove and are provided with connecting grooves 19. The first diversion groove is connected to a number of arc-shaped piston tubes 12 connected to the first arc-shaped piston rod 13. The second diversion groove is connected to a number of arc-shaped piston tubes 12 connected to the second arc-shaped piston rod 14. The external air grooves 18 connected to the second diversion groove send in high-pressure airflow. At this time, the high-pressure airflow pushes the number of second arc-shaped piston rods 14 to move, and then flips the support plate 9 upward along the flipping axis 7, flipping the flipping support plate 9 to an inclined state. Conversely, the first diversion groove enters the high-pressure airflow, and the fixed blade 10 is in a horizontal position, corresponding to the moving blade 3.

[0023] The edge treatment assembly allows for individual, non-disassembly grinding of the three moving blades 3 without affecting normal crushing operations, reducing maintenance costs and installation difficulty. The edge treatment assembly is located at the lower end of the tilting support plate 9 and includes a grinding strip 22, a reciprocating control frame 24, and a crescent gear 27. The tilting support plate 9 is horizontally positioned below the fixed blade 10 and has a reciprocating groove. Two sliding mounting rods 20 are horizontally positioned within the reciprocating groove. A reciprocating mounting plate 21 is bolted to one side of the grinding strip 22. One side of the reciprocating mounting plate 21 is inserted into the reciprocating groove and movably fitted with the two sliding mounting rods 20. The lengths of the grinding strip 22 and the reciprocating mounting plate 21 are less than the length of the reciprocating groove, while the length of the grinding strip 22 is greater than the length of the moving blade 3, allowing the reciprocating mounting plate 21 to have space for reciprocating movement within the reciprocating groove.

[0024] Please refer to Figure 6 , Figure 10 and Figure 12A reciprocating control cavity 23 is provided on the side of the reciprocating groove within the tilting support plate 9. A reciprocating control frame 24 is horizontally movable within the reciprocating control cavity 23 via a guide rod. A traction groove is provided on one side of the reciprocating control cavity 23, connecting to the reciprocating groove. A reciprocating control plate 25 is provided on one side of the reciprocating control frame 24, located in the traction groove. One side of the reciprocating control plate 25 is connected to the upper end of the reciprocating mounting plate 21. An impeller groove 26 is provided at the lower end of the reciprocating control cavity 23 within the tilting support plate 9. A synchronous shaft is rotatably inserted between the impeller groove 26 and the reciprocating control cavity 23. The synchronous shaft has crescent-shaped teeth in both the reciprocating control cavity 23 and the impeller groove 26. Wheel 27 and actuating impeller 28 are provided. The crescent gear 27 is located at the center of the reciprocating control frame 24. Several reciprocating control teeth 29 are provided on both sides of the reciprocating control frame 24 near the crescent gear 27. One side of the teeth of the crescent gear 27 is connected to one side of the reciprocating control teeth 29 of the reciprocating control frame 24. The lower end of the movable slide 5 is provided with a mounting strip 31. One side of several second arc-shaped piston rods 14 is connected to the mounting strip 31. A first valve groove is opened in the mounting strip 31. A first one-way valve 32 is inserted into the first valve groove. The crescent gear 27 and the second arc-shaped piston rod 14 are respectively passed through the first valve groove and have blowing control openings on both sides. The first transition groove 30 and the blow control groove 33 are connected through the flip support plate 9 on the side away from the first one-way valve 32. High-pressure airflow is continuously supplied into the second diversion groove. At this time, the high-pressure airflow breaks through the one-way blockage of the first one-way valve 32 and enters the impeller groove 26 from the blow control groove 33, blowing the impeller 28 to rotate, and then the impeller 28 controls the semi-circular gear 27 to rotate synchronously. When the semi-circular gear 27 rotates, since the semi-circular gear 27 is located at the center of the reciprocating control frame 24, when the teeth of the semi-circular gear 27 rotate, they will mesh with the reciprocating control teeth 29 on both sides of the reciprocating control frame 24 in sequence. The reciprocating control gear 29 on one side of the reciprocating control frame 24 first engages, controlling the reciprocating control frame 24 to move to one side. Then, when the toothed side of the crescent gear 27 rotates to the position of the reciprocating control gear 29 on the other side of the reciprocating control frame 24, the teeth and the reciprocating control gear 29 also engage, pulling the reciprocating control frame 24 back. Thus, through the engagement of the reciprocating control gear 29, the reciprocating movement of the reciprocating control frame 24 within the reciprocating control cavity 23 is achieved. Then, when the grinding strip 22 and the moving blade 3 are in relative contact, the reciprocating mounting plate 21 drives the grinding strip 22 to reciprocate at the cutting edge position of the moving blade 3, achieving the grinding effect.

[0025] A pressure relief and diversion groove 34 is horizontally formed at the upper end of the movable slide block 5 near the constraint opening 8. A second transition groove 36 is formed on one side of the pressure relief and diversion groove 34, connecting to the first diversion groove. A second valve groove is formed within the second transition groove 36, and a second one-way valve 37 is installed within the second valve groove. Several air-blowing and dispersing holes 35 are formed within the pressure relief and diversion groove 34, angled towards the fixed blade 10. When the air pressure in the first diversion groove continuously increases and breaks through the one-way blockage of the second one-way valve 37, the high-pressure airflow enters the pressure relief and diversion groove 34 from the second transition groove 36, and then is blown towards the fixed blade 10 from the several air-blowing and dispersing holes 35. The upper surface, and then under the guiding effect of the fixed blade 10 surface, blow air to cool the fixed blade 10 and the area above it. At the same time, when the blown airflow reaches the area, it can act on the moving blade 3 to a certain extent. Then, combined with the airflow cooling brought by the rotation of the moving blade 3 itself, it reduces the possibility of the moving blade 3 and the fixed blade 10 overheating and sticking to the plastic. The gas flow rate entering the pressure relief diversion groove 34 can be adjusted by controlling the gas flow rate of the air compressor equipment through the PLC, so that the airflow blown out of the blowing dispersion hole 35 can achieve relatively gentle cooling of the moving blade 3 and the fixed blade 10 after passing through the pressure relief diversion groove 34.

[0026] A process for a waste recycling device used in the production of mop plastic parts includes the following steps: Step 1: When waste plastic parts from mops need to be recycled, they are poured into the plastic recycling machine 1 from the top. At this time, the crushing control spindle 2 inside the plastic recycling machine 1 is driven to rotate by the transmission belt. The crushing control spindle 2 controls the moving blade 3 to cooperate with the fixed blade 10 set on the tilting support plate 9 to crush the plastic parts poured into the plastic recycling machine 1. Plastic particles that do not meet the required particle size are continuously disturbed in the plastic recycling machine 1 under the action of the moving blade 3 and the bottom screen 4 until plastic particles that meet the particle size are discharged from the holes of the bottom screen 4. Step 2: When the moving blade 3 is worn due to the grinding caused by rotation, the external air groove 18 connected to the second flow channel sends in high-pressure airflow. At this time, the high-pressure airflow pushes several second arc-shaped piston rods 14 to move, and then flips the support plate 9 upward along the flipping shaft 7, flipping the grinding strip 22 below the flipping support plate 9 to an inclined state. At this time, the inclination angle of the grinding strip 22 is the same as the inclination angle of the moving blade 3. Step 3: The crushing control spindle 2 rotates one of the moving blades 3 to a horizontal position. Then, the positioning telescopic rod pushes the conical positioning block 41 into the positioning hole 40 to assist in positioning the horizontal posture of the moving blade 3, so that the grinding strip 22 and the cutting edge of the moving blade 3 correspond. When it is necessary to adjust the distance between the moving blade 3 and the fixed blade 10, two or more constraint screws can be horizontally inserted into the outside of the plastic recycling machine 1 near the moving slide 5 by thread, so that the push control cylinder 6 cannot return to the initial position when controlling the moving slide 5 to reset, thereby reducing the distance between the moving blade 3 and the fixed blade 10. Step 4: Push the moving slide 5 towards the crushing control shaft 2 by the push control cylinder 6. At this time, the moving slide 5 is stably guided by the support guide tube 15. When the side of the moving constraint nut 17 contacts the plastic recycling machine 1, the grinding strip 22 just contacts the moving blade 3. Then, high-pressure airflow is continuously sent into the second diversion groove. At this time, the high-pressure airflow breaks through the one-way blockage of the first one-way valve 32 and enters the impeller groove 26 from the blowing control groove 33. It blows the rotating impeller 28, and then the rotating impeller 28 controls the semi-circular gear 27 to rotate synchronously. When the semi-circular gear 27 rotates, the reciprocating control frame 24 moves back and forth in the reciprocating control cavity 23 through the meshing control of the reciprocating control gear 29. Then, the reciprocating mounting plate 21 drives the grinding strip 22 to move back and forth at the cutting edge of the moving blade 3 to achieve the grinding effect. Step 5: When high-pressure airflow is introduced into the first diversion groove, the tilting support plate 9 can be pushed back to the horizontal position. The moving slide 5 supports the tilting support plate 9 from the bottom. The first arc-shaped piston rod 13, in conjunction with the high-pressure gas in the first diversion groove, presses the tilting support plate 9 downward to fit against the moving slide 5, ensuring the stability of the fixed blade 10 when it participates in crushing. When the air pressure in the first diversion groove continues to increase and breaks through the one-way blockage of the second one-way valve 37, the high-pressure airflow enters the pressure relief diversion groove 34 from the second transfer groove 36, and then blows it onto the upper surface of the fixed blade 10 from several blowing dispersion holes 35. Then, under the guiding effect of the fixed blade 10 surface, the area is cooled by blowing air to reduce the overheating and adhesion of plastic between the moving blade 3 and the fixed blade 10.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
