The crushing box 1 has a chamber for crushing plastic sheets; the crushing mechanism 3 is arranged inside the crushing box 1; the recycling mechanism 2 includes a recycling box 21, a filter component 22, a spray component 23 and two groups of solenoid valves 24, the recycling box 21 is arranged at the bottom of the crushing box 1, the filter component 22 is arranged inside the recycling box 21, the spray component 23 is arranged inside the crushing box 1, and the two groups of solenoid valves 24 are relatively arranged at the bottom of the crushing box 1, and the bottom end of the solenoid valve 24 is connected to the recycling box 21.

[0030] It should be noted that a feed hopper is provided above the crushing box 1 in this embodiment.

[0031] During use, the plastic sheets are fed into the crushing box 1 through the feed hopper, and then the crushing mechanism 3 is started to crush and cut the plastic sheets. Subsequently, the crushed plastic sheets fall to the bottom of the crushing box 1, and then the spray component 23 is started to spray and clean the crushed plastic sheets. After the cleaning is completed, the solenoid valve 24 is opened, and the cleaning liquid and the plastic sheets fall into the recycling box 21 together, and then the plastic sheets are separated into dry and wet parts through the filter component 22. The crushed plastic sheets can be cleaned and filtered, thereby removing dust and debris mixed in the plastic sheets and facilitating the collection work of the staff.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the filter assembly 22 includes a filter 221 and an electric push rod 222, the electric push rod 222 is hinged inside the recovery box 21, the electric push rod 222 is hinged to the bottom end of the filter 221 at one end away from the recovery box 21, the far end of the filter 221 is hinged to the recovery box 21, and the other end of the filter 221 is in contact with the side wall of the recovery box 21, and a number of ventilation holes are relatively opened on the recovery box 21.

[0033] The recovery box 21 is provided with a discharge port, and the discharge port is located at a side where the filter screen 221 and the recovery box 21 are hinged.

[0034] During actual use, in order to collect the washed plastic sheets, after the plastic sheets are separated into dry and wet states through the filter screen 221, wait for the water droplets on them to drip off, and the plastic sheets are naturally dried through the ventilation holes. After drying, start the electric push rod 222. Since one end of the filter screen 221 is hinged to the side wall of the recycling box 21, with the rotational support at one end of the filter screen 221, the electric push rod drives one end of the filter screen 221 to lift upward, causing the plastic sheets to slide downward and be sent out from the discharge port.

[0035] As Figure 1 and Figure 2 shown, in this implementation scheme, the spraying assembly 23 includes a water tank 231, a pump body 232 and two water storage plates 233. The water tank 231 is arranged on the crushing box 1, the pump body 232 is arranged on the water tank 231, the two water storage plates 233 are arranged oppositely inside the crushing box 1, a plurality of water outlet holes are formed on the side of the water storage plate 233 away from the crushing box 1, and the water storage plate 233 is located at the bottom of the crushing mechanism 3; the water inlet pipe of the pump body 232 is communicated with the water tank 231, and the water outlet pipe of the pump body 232 is communicated with any one of the water storage plates 233.

[0036] Among them, a transfer pipe is arranged between the two water storage plates 233 to communicate the two water storage plates 233 through the transfer pipe.

[0037] In order to clean the plastic sheets, by starting the pump body 232, the pump body 232 sends the cleaning water in the water tank 231 into the inside of the water storage plate 233, and sprays it out through the water outlet holes on the water storage plate 233 to perform the cleaning work on the plastic sheets.

[0038] As Figure 1 、 Figure 2 and Figure 3 shown, the crushing mechanism 3 in this implementation scheme includes a housing 31, two crushing rollers 32, two gears 33 and a first driving motor 34. The housing 31 is arranged on the crushing box 1, the two crushing rollers 32 are rotatably arranged inside the crushing box 1, and one end of the crushing roller 32 is rotatably connected inside the housing 31. The gears 33 are arranged on the crushing rollers 32, and the two gears 33 mesh with each other. The gears 33 are located inside the housing 31. The first driving motor 34 is arranged on the housing 31, and the output shaft of the first driving motor 34 is connected to any one of the crushing rollers 32. Among them, the blades on the two crushing rollers 32 are staggered.

[0039] Drive one crushing roller 32 to rotate through a driving motor 34, and the two gears 33 mesh with each other, so as to drive the two crushing rollers 32 to rotate simultaneously. The blades on the two crushing rollers 32 rotate staggeredly to crush and cut the plastic sheets.

[0040] Preferably, as Figure 1 andFigure 2 As shown in the figure, in this embodiment, it further includes a drying mechanism 4. The drying mechanism 4 includes a box body 41, a blower 42, and an electric heating plate 43. The box body 41 is arranged on the recovery box 21, the blower 42 is arranged on the recovery box 21, and the electric heating plate 43 is arranged inside the box body 41. The air outlet pipe of the blower 42 is communicated with the box body 41, and a number of air outlets communicated with the recovery box 21 are opened on the box body 41.

[0041] After the plastic sheets are cleaned and filtered, in order to accelerate the drying speed of the plastic sheets, by starting the blower 42, the blower 42 sends the external gas into the inside of the box body 41. Subsequently, the electric heating plate 43 is started to heat the gas inside the box body 41, and the heated gas is sent into the inside of the recovery box 21 through the air outlet to dry the plastic sheets.

[0042] As Figure 2 and Figure 4 shown in the figure, in this embodiment, it further includes a stirring mechanism 5. The stirring mechanism 5 includes a second driving motor 52 and a stirring rod 51. The second driving motor 52 is arranged on the crushing box 1, the stirring rod 51 is rotatably arranged inside the crushing box 1, the output shaft of the second driving motor 52 is connected to one end of the stirring rod 51, and the stirring rod 51 is located between two water storage plates 233.

[0043] In order to improve the cleaning effect of the plastic sheets, by starting the second driving motor 52, the second driving motor 52 drives the stirring rod 51 to rotate, thereby driving the plastic sheets and the cleaning water to stir together, making the plastic sheets cleaner and more thorough.

[0044] It should be noted that, as Figure 1 shown in the figure, in this embodiment, it further includes two guiding plates 6. The two guiding plates 6 are oppositely arranged inside the crushing box 1, and the end of the guiding plate 6 away from the crushing box 1 is inclined downward. The guiding plate 6 is located between the crushing mechanism 3 and the spraying assembly 23.

[0045] The two oppositely inclined guiding plates can guide the crushed plastic sheets, and at the same time prevent the cleaning water from splashing onto the crushing roller 32 during the stirring and cleaning process.

[0046] The working principle of this application is as follows:

[0047] The plastic sheets are fed into the inside of the crushing box 1 through the feed hopper. Subsequently, the crushing mechanism 3 is started. The first driving motor drives the crushing roller 32 to rotate. Through the meshing of the two gears 33, the two crushing rollers 32 are driven to rotate together. The blades on the two crushing rollers 32 rotate alternately to crush and cut the plastic sheets. The cut plastic sheets fall onto the inner bottom of the crushing box 1 under the guidance of the guiding plate 6. The spraying assembly 23 is started. The pump body 232 sends the cleaning water in the water tank 231 into the water storage plate 233 and sprays it out through the water outlet holes on the water storage plate 233 to clean the plastic sheets. At the same time, the stirring mechanism 5 is started. The second driving motor 52 drives the stirring rod 51 to rotate, thereby driving the plastic sheets and the cleaning water to stir together to improve the cleaning effect of the plastic sheets. After the cleaning is completed, the solenoid valve 24 is opened. The plastic sheets and the cleaning water fall into the recycling box 21 together and are separated into dry and wet states through the filter screen 221. The filtered plastic sheets fall above the filter screen 221. If necessary, in order to accelerate the drying speed of the plastic sheets, the drying mechanism 4 is started. The fan 42 sends the external gas into the inside of the box body 41. The electric heating plate 43 heats the gas inside the box body 41. The heated gas is sent into the recycling box 21 through the air outlet to dry the plastic sheets. After the drying is completed, the electric push rod 222 is started. Under the rotational support of one end of the filter screen 221 and the side wall of the recycling box 21, the electric push rod drives one end of the filter screen 221 to lift upward, driving the plastic sheets thereon to slide downward and be sent out through the discharge port.
