[0002] With the wide application of plastic products, the recycling and reuse of waste plastics have become an important issue of environmental protection and resource conservation. As a common plastic product, plastic film is widely used in packaging, agriculture, construction and other fields, but it is often discarded after use, causing serious environmental pollution. The recycling and disposal of waste plastic film not only can reduce environmental pollution, but also can realize the recycling of resources, with significant economic and social benefits.

[0003] In the recycling process of waste plastic film, the collected plastic film needs to be discharged first, which is usually called the discharging process. Specifically, the waste plastic film is stored in the discharging device, and after the discharging device is fixed in place, the plastic film is discharged by the mechanical force generated inside or the gravity of the plastic film itself.

[0068] When it is necessary to discharge the plastic film in the storage tank 1, the pushing plate 4 can be moved towards the discharge port 112 by manually driving the sliding rod 41, so as to extrude part of the plastic body.

[0069] Compared with the prior art, the discharging device for recycling waste plastic film provided in the embodiment can exclude the influence of humidity of the plastic film, extrude the plastic film into blocks and discharge the plastic film in batches, so as to ensure uniform discharging of the waste plastic film.

[0070] In some embodiments, as shown in Figure 4 and Figure 6 The extrusion assembly 3 includes a rotating roller 31 and a counterweight 32.

[0071] The rotating roller 31 is arranged on the upper side of the storage tank 1 in a horizontal direction and is drivingly connected with a rotating motor 311 for driving the rotation thereof.

[0077] The top cover 12 is arranged on the top of the tank body 11 to close the opening at the top of the tank body 11, and the aforementioned extrusion assembly 3 is fixedly arranged on the top cover 12.

[0078] In actual use, the top cover 12 and the extrusion assembly 3 can be recycled by separating the top cover 12 from the box body 11, so as to maintain the extrusion assembly 3 and replace parts.

[0079] In some embodiments, as shown in Figure 4 , the inner wall of the storage box 1 is provided with a protrusion 114, and the aforementioned material receiving table 2 is arranged on the protrusion 114 to limit the falling of the material receiving table 2.

[0080] In some embodiments, as shown in Figure 9 , Figure 11 and Figure 12 , the storage box 1 and the material receiving table 2 are provided with a limiting structure 6, which includes a positioning hole 61, a positioning hole 62 and a limiting rod 63.

[0081] The positioning hole 61 is arranged on the storage box 1 and communicates with the inside of the storage box 1.

[0082] The positioning hole 62 is arranged on the material receiving table 2 and is adapted to communicate with the positioning hole 61; specifically, when the material receiving table 2 moves to the protrusion 114, the positioning hole 62 and the positioning hole 61 communicate.

[0083] The limiting rod 63 is inserted into the positioning hole 61 and the positioning hole 62 which communicate with each other, so as to limit the movement of the material receiving table 2 relative to the storage box 1.

[0084] Among them, one end of the limiting rod 63 has an end head 631 for abutting against the outer side surface of the storage box 1, and the other end is threadedly connected with a stop nut 632 for abutting against the other side of the storage box 1; by abutting against the opposite sides of the storage box 1 through the end head 631 and the stop nut 632, the movement of the limiting rod 63 along the axial direction of itself can be limited.

[0085] In some embodiments, as shown in Figure 4 and Figure 5 , the material blocking member 5 includes two guide rails 51 and a lifting plate 52.

[0086] The two guide rails 51 are fixedly arranged on the outer side surface of the storage box 1 and symmetrically arranged on both sides of the discharge port 112.

[0087] The lifting plate 52 is arranged on the outer side surface of the storage box 1, and the two sides of the lifting plate 52 are respectively connected with the two guide rails 51 in the up-down direction to be adapted to move to close or avoid the discharge port 112.

[0088] Among them, the upper side surface of the lifting plate 52 is rotatably connected with a hanging arm 521 for abutting against or avoiding the upper end surface of the guide rail 51 in the up-down direction.

[0089] In some embodiments, as shown in Figure 4 , Figure 8 andFigure 12 As shown in the drawings, the storage box 1 is provided with a strip-shaped hole 115 which is in communication with the upper chamber and is located at the side of the pushing plate 4 away from the discharge port 112.

[0090] Based on this, the pushing plate 4 further comprises a supporting belt 42 and an elastic member 7.

[0091] The supporting belt 42 is fixedly connected to the pushing plate 4 and extends out of the storage box 1 through the strip-shaped hole 115.

[0092] The elastic member 7 is fixedly arranged on the outer wall of the storage box 1 and is connected to the extending end of the supporting belt 42.

[0093] By adopting the above technical scheme, when the pushing plate 4 moves towards the discharge port 112, the supporting belt 42 is adapted to support the plastic film to limit the falling of the plastic film, and the elastic member 7 is elastically energized. When the pushing plate 4 moves away from the discharge port 112 to the initial position, the supporting belt 42 can pull the supporting belt 42 outwards under the action of the elastic member 7, so as to make the supporting belt 42 disengage from the upper chamber, thereby facilitating the falling of the plastic block above to the upper side of the material receiving table 2.

[0094] In some embodiments, as shown in Figure 1 , Figure 4 and Figure 8 , the outer side of the storage box 1 away from the discharge port 112 has an outwardly extending boss 116; based on this, the elastic member 7 comprises a lifting rod 71 and a spring 72.

[0096] The spring 72 is sleeved on the lifting rod 71, and the upper and lower ends of the spring 72 are respectively connected to the upper end of the lifting rod 71 and the upper side of the boss 116.

[0097] By adopting the above technical scheme, when the pushing plate 4 moves towards the discharge port 112, the lifting rod 71 moves downwards and the spring 72 is elastically deformed.

[0098] In some embodiments, as shown in Figures 1 to 3 , a plurality of universal wheels 117 are fixedly arranged on the bottom of the storage box 1 to facilitate manual pushing.

[0099] In some embodiments, as shown in Figure 4 and Figure 10 , a water absorption pad 8 is arranged in the lower chamber, and after the water absorption pad 8 is placed in the lower chamber, the water absorption pad 8 can fill the space in the lower chamber and prevent the flow of liquid.

[0100] The outer side of the storage tank 1 is hinged with a anti-off plate 9 for closing or avoiding the water outlet 113. The anti-off plate 9 prevents the water absorbing pad 8 from passing through the water outlet 113, so as to store the liquid and ensure the neatness of the site environment.

[0101] The above merely provides the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
