[0002] At present, the application scope of greenhouse film is very wide, so a lot of waste greenhouse film is generated. Waste greenhouse film is generally pre-treated through steps such as collection, sorting, crushing and cleaning. After pre-treatment, it is melted into renewable plastic particles for recycling. Cleaning waste greenhouse film can remove pollutants such as dust, sand, dirt attached to the surface, reduce harmful gases and waste generated during the plastic melting process, and at the same time ensure that the quality of the produced plastic particles is purer and more uniform, thereby improving the quality of recycled plastic products.

[0003] The existing method of cleaning waste film is to put the broken waste film into a cleaning tank, and then stir and clean the waste film through a stirring plate, but this cleaning method has the following shortcomings: 1. When the cleaning method of stirring with a stirring plate is adopted, since the weight of the broken waste film is small, the waste film is easy to float on the water surface and flow with the water body, the interaction effect between the waste films is poor, and some waste films will stick together, resulting in that the dirt on the surface of the waste film is difficult to clean, and the cleaning effect of the waste film is poor; 2. When the stirring plate stirs the waste film, the waste film soaked in water is easy to adhere to the stirring plate, resulting in insufficient cleaning of the waste film, affecting the cleaning effect of the waste film, and further affecting the quality of the recycled plastic products.

In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0031] See also Figure 1 , Figure 2 and Figure 3The stirring mechanism 2 includes a stirring shaft 21 rotatably mounted between the middle of the top plate 13 and the inner bottom wall of the cleaning tank 1, and the outside of the stirring shaft 21 is fixedly connected with a plurality of first cleaning forks 22 evenly arranged in the circumferential direction, and the outside of the stirring shaft 21 is fixedly sleeved with an upper turntable 23 located above the first cleaning forks 22, and the upper turntable 23 is rotatably mounted inside the cleaning tank 1, and the output shaft of the drive motor 7 is fixedly connected to the top of the stirring shaft 21.

[0032] See also Figure 2 , Figure 3 and Figure 4 The scrubbing mechanism 3 includes a reciprocating assembly 31 installed at the bottom of the upper turntable 23, a side changing assembly 32 is installed on the side of the reciprocating assembly 31 close to the stirring shaft 21, a second cleaning fork 33 matching with the first cleaning fork 22 is installed on the side of the side changing assembly 32 close to the stirring shaft 21, and a material blocking assembly 34 is also arranged between the side changing assembly 32 and the reciprocating assembly 31.

[0033] See also Figure 1 , Figure 2 and Figure 3 The backwash mechanism 5 includes a backwash component 51 installed inside the cleaning tank 1 , and a transmission component 52 is installed at the bottom of the backwash component 51 for driving the backwash component 51 to rotate in the opposite direction through the rotation of the stirring mechanism 2 .

[0034] See also Figure 3 , Figure 4 and Figure 5 The reciprocating moving component 31 includes a sliding groove frame 311 fixedly connected to the bottom of the upper turntable 23, a lead screw 312 is rotatably installed inside the sliding groove frame 311, a slider 313 is threadedly sleeved on the outer surface of the lead screw 312, and the slider 313 is installed inside the sliding groove frame 311 to slide up and down, and the side changing component 32 is arranged on the slider 313.

[0035] The slider 313 is driven upward or downward by the rotation of the lead screw 312, and then the slider 313 drives the side-changing assembly 32 and the second cleaning fork 33 to move upward or downward, so that the second cleaning fork 33 can cooperate with the first cleaning fork 22 to scrub the waste film up and down. The second cleaning fork 33 moving up and down can also press the waste film into the water, thereby improving the cleaning effect of the waste film.

[0036] See also Figure 3 , Figure 4 and Figure 5The side-changing assembly 32 includes a slide seat 321 horizontally slidably mounted on the side of the slider 313 close to the stirring shaft 21, and a rubber pad 322 is installed on the side of the slider 313 close to the slide seat 321. The rubber pad 322 is used to increase the resistance of the slide seat 321 to prevent the slide seat 321 from sliding randomly. The second cleaning fork 33 is fixedly mounted on the side of the slide seat 321 close to the stirring shaft 21, and the top and bottom of the slide seat 321 are both provided with inclined surfaces, and the inclination directions of the upper and lower inclined surfaces are opposite and parallel to each other. The upper and lower ends of the sliding groove frame 311 are respectively fixedly mounted with an upper pushing block 323 and a lower pushing block 324 that match the corresponding inclined surfaces, and the upper pushing block 323 and the lower pushing block 324 are located on the same diagonal line of the sliding groove frame 311.

[0037] When the slider 313 drives the slide 321 to move to the top or bottom of the slide slot frame 311, the upper pushing block 323 or the lower pushing block 324 can give the slide 321 a pushing force to move horizontally, so that the slide 321 moves horizontally from one side of the slider 313 to the other side, thereby completing the position adjustment of the second cleaning fork 33. Figure 6 As shown, the second cleaning fork 33 and the first cleaning fork 22 can alternately clean the waste film adhered to the outer side of each other.

[0038] See also Figure 4 and Figure 5 The material blocking assembly 34 includes a corrugated folded plate 341 fixedly connected between the upper and lower ends of the slider 313 and the inner wall of the sliding groove frame 311. A guide groove 343 parallel to the moving direction of the slider 313 is opened on the inner wall of the sliding groove frame 311. A plurality of equidistantly arranged guide blocks 342 are fixedly connected to the side of the corrugated folded plate 341 close to the guide groove 343. The guide blocks 342 are slidably installed inside the guide groove 343.

[0039] During the up and down movement of the slider 313, the corrugated folding plate 341 can be stretched and deformed up and down, and the guide block 342 slides up and down inside the guide groove 343, which supports and limits the corrugated folding plate 341, so that the edge of the corrugated folding plate 341 is always in contact with the inner wall of the sliding groove frame 311. The corrugated folding plate 341 blocks the gap between the sliding groove frame 311 and the slider 313, which can prevent waste film from entering the interior of the sliding groove frame 311 and affecting the normal movement of the slider 313.

[0040] See also Figure 3 and Figure 6 The first cleaning fork 22 and the second cleaning fork 33 are both U-shaped structures and correspond to each other one by one. The first cleaning fork 22 and the second cleaning fork 33 are staggered up and down and the opening ends are opposite to each other.

[0041] See also Figure 2 , Figure 3 and Figure 7The transmission mechanism 4 includes an inner gear ring 41 and an outer gear ring 42 which are fixedly connected to the bottom of the top plate 13 and are concentrically arranged. The center of the inner gear ring 41 coincides with the axis of the stirring shaft 21. A plurality of driving wheels 43 are arranged between the inner gear ring 41 and the outer gear ring 42. The driving wheel 43 is fixedly connected to the top of the lead screw 312. The outer ring surface of the inner gear ring 41 and the inner ring surface of the outer gear ring 42 are both provided with a plurality of meshing sections, and the meshing sections on the two are equal in length. The meshing sections on the inner gear ring 41 and the outer gear ring 42 are alternately meshed with the driving wheel 43.

[0042] When the stirring shaft 21 drives the scrubbing mechanism 3 to rotate through the upper turntable 23, the screw 312 will drive the driving wheel 43 to rotate around the inner gear ring 41. During this process, the driving wheel 43 will alternately engage with the meshing sections on the inner gear ring 41 and the outer gear ring 42. When the driving wheel 43 engages with the meshing section of the inner gear ring 41, it will rotate clockwise. When the driving wheel 43 engages with the meshing section of the outer gear ring 42, it will rotate counterclockwise. By driving the screw 312 to rotate periodically in the forward and reverse directions through the driving wheel 43, the slider 313 can drive the second cleaning fork 33 to move up and down periodically, so that the second cleaning fork 33 and the first cleaning fork 22 can cooperate to scrub the waste film up and down.

[0043] See also Figure 2 , Figure 3 and Figure 8 The backwash assembly 51 includes a lower turntable 511 rotatably mounted inside the cleaning tank 1 , a plurality of cleaning rods 512 are fixedly connected to the top of the lower turntable 511 , and a through hole is provided in the middle of the lower turntable 511 for the bottom end of the stirring shaft 21 to pass through.

[0044] See also Figure 2 , Figure 3 and Figure 8 The transmission assembly 52 includes a transmission gear ring 521 fixedly connected to the bottom of the lower turntable 511. The bottom end of the stirring shaft 21 passes through the bottom of the lower turntable 511 and is fixedly connected to a first transmission gear 522. The first transmission gear 522 is located at the inner center of the transmission gear ring 521. The first transmission gear 522 is connected to the transmission gear ring 521 through a meshing second transmission gear 523. The second transmission gear 523 is rotatably installed at the bottom of the inner cavity of the cleaning tank 1.

[0045] When the stirring shaft 21 rotates, it will drive the transmission ring gear 521 to rotate together. The transmission ring gear 521 will then drive the transmission ring gear 521 to rotate through the transmission of the second transmission gear 523. Then the transmission ring gear 521 drives the lower turntable 511 to rotate in the opposite direction of the stirring shaft 21, so that the upper and lower layers of waste film can be cleaned by friction in a bidirectional motion, which is beneficial to removing dirt adhered to the surface of the waste film.

[0046] See also Figure 2 , Figure 3 and Figure 8 The lifting mechanism 6 includes a push plate 61 slidably mounted outside the cleaning rod 512, a lifting assembly 62 for driving the push plate 61 to move up and down is arranged at the bottom of the push plate 61, and an electric telescopic rod 63 for driving the lifting assembly 62 to operate is fixedly installed at the bottom of the lower turntable 511.

[0047] See also Figure 2 and Figure 8 The lifting assembly 62 includes a plurality of lifting blocks 621 fixedly connected to the bottom of the pushing plate 61 and arranged circumferentially, the bottom end of the lifting block 621 slides through the bottom of the lower turntable 511, and a return spring 622 is fixedly connected between the bottom end of the lifting block 621 and the lower surface of the lower turntable 511, and a driving ring 623 is rotatably installed at the bottom of the lower turntable 511, and a plurality of wedge blocks 624 matching the lifting blocks 621 are fixedly connected to the inner ring surface of the driving ring 623, and a round rod matching the inclined surface of the corresponding wedge block 624 is arranged on the lower side of the lifting block 621, and a ball is arranged on the end of the round rod away from the corresponding lifting block 621, and a push handle 625 is fixedly connected to the outer ring surface of the driving ring 623, and a pin is rotatably installed at the end of the output shaft of the electric telescopic rod 63, and the pin is slidably installed in the push handle 625, and the power supply connected to the electric telescopic rod 63 is installed on the driving ring 623. The ball bearings are used to reduce the friction between the round rod and the inclined surface of the wedge block 624, so that the lifting block 621 can move upward smoothly.

[0048] When used specifically, step one: put the broken waste film into the cleaning tank 1 from the feed port 11, then start the drive motor 7, drive the stirring shaft 21 to rotate through the drive motor 7, and then drive the first cleaning fork 22 to rotate through the stirring shaft 21, so that the first cleaning fork 22 stirs and cleans the waste film.

[0049] Step 2: The stirring shaft 21 drives the sliding groove frame 311 to rotate together through the upper turntable 23, and the driving wheel 43 located at the top of the screw 312 will rotate around the inner ring 41 driven by the screw 312. When the driving wheel 43 engages with the meshing section of the inner ring 41, the inner ring 41 drives the driving wheel 43 to rotate clockwise, and then the driving wheel 43 drives the screw 312 to rotate clockwise, so that the slider 313 moves upward along the screw 312, thereby driving the second cleaning fork 33 to move upward.

[0050] Step three: When the slider 313 is close to the top of the sliding slot frame 311, the upper pushing block 323 contacts the top of the sliding seat 321 and pushes the sliding seat 321 to slide laterally, so that the sliding seat 321 drives the second cleaning fork 33 to adjust its position. When the slider 313 completely reaches the top of the sliding slot frame 311, the driving wheel 43 separates from the meshing section of the inner gear ring 41 and meshes with the meshing section of the outer gear ring 42. At this time, the outer gear ring 42 drives the driving wheel 43 to rotate counterclockwise, causing the screw 312 to rotate in the opposite direction and drive the slider 313 to move downward.

[0051] Step 4: When the slider 313 is close to the bottom of the sliding groove frame 311, the lower pushing block 324 will contact the top of the sliding seat 321 and push the sliding seat 321 to slide laterally in the opposite direction, so that the sliding seat 321 drives the second cleaning fork 33 to adjust its position again. When the slider 313 completely reaches the bottom of the sliding groove frame 311, the driving wheel 43 is separated from the meshing section of the outer gear ring 42 and re-engaged with the meshing section of the inner gear ring 41, so that the driving wheel 43 rotates clockwise again, and then repeats steps 2, 3, and 4, so that the second cleaning fork 33 continuously moves back and forth up and down and adjusts its position, and the second cleaning fork 33 is used to cooperate with the first cleaning fork 22 to rub the waste film up and down, and at the same time, the second cleaning fork 33 is used to stir and clean the waste film in the up and down directions, and the waste film floating on the upper layer is pressed into the water for cleaning.

[0052] Step 5: When the stirring shaft 21 rotates, it will drive the first transmission gear 522 to rotate together, and then the first transmission gear 522 drives the transmission ring gear 521 to rotate through the transmission of the second transmission gear 523, and then the transmission ring gear 521 drives the lower turntable 511 and the cleaning rod 512 to rotate in the opposite direction. Through the reverse rotation of the first cleaning fork 22 and the cleaning rod 512, the upper and lower layers of waste films can be cleaned by friction in a bidirectional motion, thereby improving the cleaning effect.

[0053] Step 6: After the cleaning is completed, start the electric telescopic rod 63, and use the electric telescopic rod 63, the pin shaft and the push handle 625 to drive the drive ring 623 to rotate, and then the drive ring 623 drives the wedge block 624 to rotate and squeeze the lifting block 621, so that the lifting block 621 pushes the push plate 61 to move upward until it is flush with the cleaning rod 512. At this time, the upper end surface of the push plate 61 is also flush with the inner bottom wall of the discharge port 12, and then the valve in the discharge port 12 is opened to allow the waste film to be discharged outward with the water flow.
