Description

Technical Field

[0001] The utility model belongs to the technical field of plastic sheet recycling, and specifically relates to a surface cleaning device for plastic sheet recycling. Background Technique

[0002] Plastic sheets are processed with high molecular polymers as the matrix and functional auxiliaries such as plasticizers, antioxidants, and flame retardants as accessories. They have excellent properties such as high temperature resistance, corrosion resistance, and wear resistance, and are widely used in industries and manufacturing such as chemical industry, automotive, and aerospace. With the continuous development of technology, while the performance of plastic sheets is continuously improved, a large number of waste plastic sheets will also be generated. If these plastic sheets are not recycled, it will not only waste a large amount of resources, but also cause serious harm to the environment and human health.

[0003] In the prior art, when cleaning the surface of recycled plastic sheets, water is usually directly sprayed in the cleaning tank, and the sheets are brushed with the cooperation of brushes. Moreover, water continues to flow out in the area without sheets, resulting in a large amount of water consumption during cleaning, wasting water resources and increasing the cost of subsequent sewage treatment. Content of the Utility Model

[0011] Further, a limiting piece is sleeved and fixed above the square pipe, and the limiting piece is located inside the brush handle; the limiting piece can limit the brush handle to prevent the brush handle from disengaging from the square pipe during sliding.

[0012] Further, the flow control assembly includes two cooperating movable doors. Through the cooperation of the movable doors, the bottom end of the square pipe can be sealed or opened. The middle part of the top end of the movable door is hinged to the bottom end of the square pipe. A chute is opened at the bottom end of the movable door, and a slider is slidably connected in the chute. A fixed rod is arranged below the movable door. One end of the fixed rod is hinged to the slider, and the other end of the fixed rod is fixedly connected to the hollow brush head; the flow control assembly can ensure that the cleaning water does not flow out when there is no plastic sheet passing through, and can reduce the waste of water resources.

[0013] Further, the drying mechanism includes a hot air blower. The output end of the hot air blower is fixedly connected with a plurality of uniformly distributed ventilation pipes. The air outlet ends of the ventilation pipes penetrate through the top end of the cleaning box and are fixedly installed with air outlet heads; through the drying mechanism, the surface of the plate after brushing can be dried, preventing the collected plastic plates from breeding bacteria in a humid environment and affecting the processing of the plates.

[0014] Further, an inclined plate is fixedly installed at one end of the conveyor belt close to the dryer. A material box is arranged below the inclined plate to recycle the cleaned plastic plates.

[0015] Advantages of the present utility model:

[0016] At the bottom of the hollow brush head of the brushing mechanism of the present utility model, there are through holes and a flow control assembly is cooperatively arranged inside the hollow brush head. By opening and closing the movable doors in the flow control assembly, on the one hand, continuous water supply and brushing on the surface of the plastic sheet can be achieved, and on the other hand, when there is no sheet, no cleaning water will flow out, effectively reducing the waste of water resources during the surface cleaning of plastic sheets and reducing the cost of recycling and processing plastic sheets.

[0017] The drying mechanism of the present utility model can dry the plates after brushing, effectively improving the processing efficiency of the plates in the later stage, and at the same time can effectively prevent the collected plastic plates from breeding bacteria in a humid environment and improving the recycling and processing environment.

The filter screen 102 is fixedly connected to the peripheral side of the inner wall of the cleaning box 1. On one side of the top of the cleaning box 1, a water inlet assembly 2 is arranged. A conveyor belt 3 penetrates through the inside of the cleaning box 1. A brushing mechanism 4 is installed between the conveyor belt 3 and the water inlet assembly 2. On the other side of the top of the cleaning box 1, a drying mechanism 5 is arranged. At one end of the conveyor belt 3 close to the drying mechanism 5, an inclined plate 6 is fixedly installed. Below the inclined plate 6, a material box 7 is arranged.

[0029] The water inlet assembly 2 includes a water tank 201. A water inlet pipe 202 is fixedly installed at the top of the water tank 201. At the bottom of the water tank 201, a number of square pipes 203 are arranged. The top of the square pipe 203 penetrates through the top of the cleaning box 1 and is fixedly connected to the water tank 201. A limiting piece 204 is sleeved and fixed on the square pipe 203.

[0030] The brushing mechanism 4 includes a number of hollow brush heads 401. A number of uniformly distributed through holes are opened at the bottom of the hollow brush head 401. At the center of the top of the hollow brush head 401, a brush handle 402 is arranged. The bottom of the brush handle 402 is fixedly connected to the hollow brush head 401. The bottom of the square pipe 203 penetrates through the top of the brush handle 402 and is slidably and sealedly connected to the brush handle 402. At the same time, the limiting piece 204 is located inside the brush handle 402. A flow control component 403 is arranged inside the hollow brush head 401. The flow control component 403 includes two mutually cooperating movable doors 4031. The middle of the movable door 4031 is hinged to the bottom of the square pipe 203. A chute is opened at the bottom of the movable door 4031. A slider 4032 is slidably connected to the chute. Below the movable door 4031, a fixed rod 4033 is arranged. One end of the fixed rod 4033 is hinged to the slider 4032, and the other end of the fixed rod 4033 is fixedly connected to the bottom of the hollow brush head 401.

[0031] The drying mechanism 5 includes a hot air blower 501. The output end of the hot air blower 501 is fixedly connected to a number of uniformly distributed ventilation pipes 502. The air outlet end of the ventilation pipe 502 penetrates through the top of the cleaning box 1 and is fixedly installed with an air outlet head 503.

[0032] Working principle:

[0033] During operation, the cleaning water enters the water tank 201 through the water inlet pipe 202 and fills the square pipe 203. Place the plastic sheet on the conveyor belt 3, start the motor of the conveyor belt 3, and the plastic sheet enters the cleaning box 1 under the transportation of the conveyor belt 3. When the sheet reaches below the brushing mechanism 4, the plastic sheet will lift the hollow brush head 401. When the hollow brush head 401 slides upward along the square pipe 203, it drives the fixing rod 4033 to move upward. The upward movement of the fixing rod 4033 drives the sliding of the slider 4032, thereby opening the two movable doors 4031. The cleaning water flows out through the square pipe 203 and flows to the surface of the plastic sheet through the through hole at the bottom end of the hollow brush head 401, and brushes the sheet as the sheet moves. When the plastic sheet leaves the brushing mechanism 4, the hollow brush head 401 falls under the action of gravity. When the brush handle 402 falls back onto the limit piece 204, the movable door 4031 closes, and the cleaned sewage seeps out from the filter net 102 and then is discharged from the drain pipe 101.

[0034] When the plastic sheet passes through the drying mechanism 5, start the hot air blower 501. The hot air enters the ventilation pipe 502 and blows out from the air outlet head 503, thereby drying the cleaning water on the surface of the plastic sheet. After drying is completed, it then slides down from the inclined plate 6 into the material box 7 for collection.
