Description

Technical Field

[0001] This utility model relates to the field of waste plastic processing technology, specifically a waste plastic recycling and cleaning machine. Background Technology

[0002] Waste plastics refer to plastic products or materials that have been discarded or lost their original use value. They include plastic waste generated in daily life, industry, agriculture, medical fields, etc. They are not biodegradable. Most traditional plastics take hundreds of years to decompose in the natural environment. They have a wide range of sources, including packaging, electronic products, construction waste, agricultural film, etc. They are recyclable. Some plastics can be recycled and reused through physical or chemical methods. Waste plastic recycling cleaning machines are key equipment in plastic recycling production lines. They are mainly used to remove stains, labels, residual liquids and other impurities from plastic fragments to improve the purity of recycled plastics.

[0003] Some existing waste plastic recycling and cleaning machines work by injecting waste plastic into the cleaning tank, and then driving the reamer through the rotating shaft under the drive of the motor. When rotating, the material is strongly agitated, and the friction between the reamer and the material and between the materials achieves the cleaning effect.

[0004] Existing waste plastic recycling and cleaning machines of this type have the following problems: when cleaning waste plastics, simple rotation and stirring will create friction dead corners, which will easily lead to excessive friction in some areas and insufficient cleaning in others, thus reducing the cleaning effect of waste plastics. Therefore, we propose a waste plastic recycling and cleaning machine. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a waste plastic recycling cleaning machine. When cleaning waste plastics, it avoids friction dead angles through compound motion friction, and the overall friction range is larger and more thorough, thereby improving the cleaning effect of waste plastics and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste plastic recycling cleaning machine, including a support frame, a cleaning tank at the upper end of the support frame, a water pipe at the upper end of the cleaning tank, and uniformly distributed nozzles at the lower end of the water pipe, and also including a friction cleaning mechanism.

[0007] Friction cleaning mechanism: It includes a transfer column, a transfer block, a support plate, a sealed bearing, a rotating shaft, a rubber sealing ring, a rotating shaft, and steel brushes. The left end of the cleaning tank is provided with a transfer column, and the transfer block is rotatably connected inside the transfer column. The right end of the transfer block is provided with a support plate, and the right end of the support plate is rotatably connected to a uniformly distributed rotating shaft through a sealed bearing. The rotating shaft is fixedly connected between the left and right inner walls of the cleaning tank. The rotating shaft and the outer surface of the rotating shaft are respectively provided with uniformly distributed steel brushes. A rubber sealing ring is provided between the right side of the inner wall of the transfer column and the right side of the outer surface of the transfer block. When cleaning waste plastics, the compound motion friction avoids friction dead angles, and the overall friction range is larger and more thorough, improving the cleaning effect of waste plastics.

[0008] Furthermore, a control switch is provided on the outside of the bracket, and the input terminal of the control switch is electrically connected to an external power source to provide electrical connection for electrical appliances.

[0009] Furthermore, the friction cleaning mechanism also includes a drive assembly, which includes gear one and gear two. Gear one is fixedly sleeved on the left side of the outer surface of the rotating shaft, and gear two is fixedly connected to the left end of the rotating shaft. Gear two is meshed with gear one to provide rotational connection.

[0010] Furthermore, the drive assembly also includes a worm gear, a worm, and a protective cover. The protective cover is located in the middle of the left end of the cleaning tank. A worm gear is fixedly sleeved on the left side of the outer surface of the adapter block. A worm is rotatably connected to the top wall of the protective cover. The worm gear and the worm are meshed together to provide a rotatable connection.

[0011] Furthermore, the drive assembly also includes a motor, which is located on the rear side of the upper end of the protective cover. The lower end of the motor's output shaft is fixedly connected to the upper end of the worm gear, and the input end of the motor is electrically connected to the output end of the control switch to provide rotation drive.

[0012] Furthermore, the cleaning box has a feeding trough at the upper inlet and a discharge trough at the lower right outlet. The right outlet of the cleaning box is hinged with a door for easy loading and unloading.

[0013] Furthermore, a drain pipe is provided at the water outlet on the lower left side of the cleaning tank for easy drainage.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This waste plastic recycling and washing machine has the following advantages:

[0015] Driven by the motor, the worm gear meshes with the worm wheel, causing the adapter block to rotate within the adapter column, which in turn drives the support plate to rotate. The support plate, through a sealed bearing, drives the rotating shaft to revolve. Then, gear two meshes with gear one, causing the rotating shaft to rotate on its own axis. Due to the combined motion of the rotating shaft and the steel brush on it, the rotating shaft and the steel brush on the shaft generate all-round friction on the plastic inside the cleaning tank, removing surface stains. When cleaning waste plastics, the combined motion friction avoids dead angles, resulting in a larger and more thorough overall friction range, thus improving the cleaning effect of waste plastics.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a waste plastic recycling and cleaning machine, including a support 1, a cleaning tank 2 at the upper end of the support 1, a water pipe 3 at the upper end of the cleaning tank 2, and evenly distributed nozzles 4 at the lower end of the water pipe 3. It also includes a friction cleaning mechanism 5. A control switch 9 is located outside the support 1, and the input terminal of the control switch 9 is electrically connected to an external power source. A feeding trough 7 is located at the feeding port at the upper end of the cleaning tank 2, and a discharge trough 8 is located at the discharge port on the lower right side of the cleaning tank 2. A door is hinged to the discharge port on the right side of the cleaning tank 2. (A door lock is provided between the door and the edge of the discharge port. The door lock adopts a rotary latch lock structure commonly used in the prior art. The rotary latch lock achieves the locking function through a rotating cam structure.) The mechanical device consists of a lock cylinder, lock tongue, base and other components. A sealing ring can be set at the edge of the door to ensure that the door is sealed and does not leak after it is closed. A drain pipe 6 is provided at the water outlet on the lower left side of the cleaning tank 2. When cleaning waste plastic, the waste plastic to be cleaned is put into the cleaning tank 2 from the feed trough 7 through the feed inlet at the upper end of the cleaning tank 2. The water pipe 3 is connected to the external water source to ensure that the nozzle 4 can spray water normally. After cleaning, the motor 595 and water source are turned off by the control switch 9, the door of the discharge port on the right side of the cleaning tank 2 is opened, and the cleaned plastic is discharged through the discharge trough 8. The drain pipe 6 is opened to discharge the wastewater generated during cleaning from the cleaning tank 2, completing a complete cleaning process.

[0023] Friction cleaning mechanism 5: It includes a transition column 51, a transition block 52, a support plate 53, a sealed bearing 54, a rotating shaft 55, a rubber sealing ring 56, a rotating shaft 57, and a steel brush 58. The left end of the cleaning tank 2 is provided with a transition column 51, and the transition block 52 is rotatably connected inside the transition column 51. The right end of the transition block 52 is provided with a support plate 53, and the right end of the support plate 53 is rotatably connected to evenly distributed rotating shafts 55 through the sealed bearing 54. (The sealing rubber gasket inside the sealed bearing 54 can be replaced to prevent water from seeping into the interior of the support plate 53 and avoid damage to the connecting parts). The rotating shaft 57 is fixedly connected between the left and right inner walls of the cleaning tank 2. (A clearance hole is provided between the right end of the support plate 53 and the outer surface of the rotating shaft 57.) A sealing ring (which can be replaced periodically to prevent water from seeping into the support plate 53 and damaging the connecting parts) is provided on the outer surfaces of the rotating shaft 55 and the rotating shaft 57, respectively. A rubber sealing ring 56 is provided between the right side of the inner wall of the adapter column 51 and the right side of the outer surface of the adapter block 52 (the rubber sealing ring 56 can be replaced periodically to prevent wear from prolonged use and to prevent water leakage from the cleaning tank 2). The friction cleaning mechanism 5 also includes a drive assembly 59, which includes a first gear 591 and a second gear 592. The first gear 591 is fixedly sleeved on the left side of the outer surface of the rotating shaft 57, and the second gear 592 is fixedly connected to the left end of the rotating shaft 55. The second gear 592 is connected to the first gear 591 and the second gear 592. The gear 591 meshes with the drive assembly 59, which also includes a worm gear 593, a worm 594, and a protective cover 596. The protective cover 596 is located in the middle of the left end of the cleaning tank 2. The worm gear 593 is fixedly sleeved on the left side of the outer surface of the adapter block 52. The worm 594 is rotatably connected to the top wall of the protective cover 596. The worm gear 593 meshes with the worm 594. The drive assembly 59 also includes a motor 595, which is located on the rear side of the upper end of the protective cover 596. The lower end of the output shaft of the motor 595 is fixedly connected to the upper end of the worm 594. The input end of the motor 595 is electrically connected to the output end of the control switch 9. By adjusting the control switch 9, the motor 595 operates, and the output shaft of the motor 595 drives the worm 594 to rotate. 94 meshes with the worm gear 593 outside the adapter block 52, causing the adapter block 52 to rotate inside the adapter column 51, which in turn drives the support plate 53 to rotate synchronously. When the support plate 53 rotates, the rotating shaft 55 connected by the sealed bearing 54 revolves with it. At the same time, the gear 2 592 at the left end of the rotating shaft 55 meshes with the gear 1 591 outside the fixed rotating shaft 57, causing the rotating shaft 55 to rotate on its own. Due to the combined motion of revolution and rotation, the steel brush 58 on the rotating shaft 55 and the rotating shaft 57 generates all-round friction on the plastic in the cleaning tank 2, peeling off the surface stains. The clean water in the water pipe 3 is evenly sprayed onto the plastic surface through the nozzle 4. The water flow softens the stains and washes away the dirt peeled off by the steel brush 58, avoiding secondary adhesion and enhancing the cleaning effect.

[0024] The working principle of the waste plastic recycling cleaning machine provided by this utility model is as follows: When cleaning waste plastic, the waste plastic to be cleaned is put into the cleaning tank 2 from the feed trough 7 through the feed inlet at the top of the cleaning tank 2. The water pipe 3 is connected to an external cleaning water source with a certain water pressure (or an external water pump) to ensure that the nozzle 4 can spray water normally. By controlling the switch 9, the motor 595 operates. The output shaft of the motor 595 drives the worm 594 to rotate. The worm 594 meshes with the worm wheel 593 outside the adapter block 52, so that the adapter block 52 rotates in the adapter column 51, thereby driving the support plate 53 to rotate synchronously. When the support plate 53 rotates, the rotating shaft 55 connected by the sealed bearing 54 revolves with it. At the same time, the gear 2 592 at the left end of the rotating shaft 55 meshes with the gear 1 591 outside the fixed rotating shaft 57, so that the rotating shaft 55 rotates from its own rotation. The body rotates, and the steel brushes 58 on the rotating shaft 55 and rotating shaft 57 generate all-round friction on the plastic inside the cleaning tank 2 due to the combined motion of revolution and rotation, peeling off surface stains. Clean water in the water pipe 3 is evenly sprayed onto the plastic surface through the nozzle 4. The water flow softens the stains and washes away the dirt peeled off by the steel brushes 58, preventing secondary adhesion and enhancing the cleaning effect. After cleaning, the motor 595 and water source are turned off by the control switch 9, and the drain pipe 6 is opened to discharge the wastewater generated during cleaning into the cleaning tank 2. Then the drain pipe 6 is closed (a butterfly valve of existing technology can be installed at the drain pipe 6). Water is sprayed again through the nozzle 4 to clean the old plastic surface attachments. This process is repeated at least three times. After that, the water is completely drained through the drain pipe 6. Then the lock of the door of the discharge port on the right end of the cleaning tank 2 is opened, and the cleaned plastic is discharged through the discharge chute 8, completing a complete cleaning process.

[0025] It is worth noting that the motor 595 disclosed in the above embodiments can be YJ61, and the control switch 9 is provided with a switch button corresponding to the motor 595 and used to control its switching operation.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
