[0026] like Figures 1-4 The waste film crushing device shown is characterized by comprising: a shell 1, a crushing unit, a screening unit, a return material conveying unit, and a switching valve.

[0027] like Figure 1 and Figure 2 As shown, the interior of the shell 1 is hollow to form a processing chamber. The processing chamber is provided with a vertical partition 2, which divides the processing chamber into a crushing chamber on the left and a reflux chamber on the right. The upper side of the partition 2 is provided with a return port 3, and the lower side is provided with a discharge port 4. The return port 3 and the discharge port 4 are respectively connected to the crushing chamber and the reflux chamber. The top of the crushing chamber is provided with a feeding port, and the bottom is provided with a first discharge port 5. The top right side of the reflux chamber is provided with a second discharge port 6.

[0028] The pulverizing unit includes a first driving component and two pulverizing wheels 7 arranged side by side. The pulverizing wheels 7 are rotatably mounted in the pulverizing chamber. The first driving component is connected to the two pulverizing wheels 7 to drive them to rotate. In a specific configuration, the first driving component includes a first motor. Driven gears are respectively provided on the axles of the two pulverizing wheels 7, and the two driven gears mesh with each other. A driving gear is provided on the motor shaft of the first motor, and the driving gear meshes with one of the driven gears. Thus, the first motor can drive the two pulverizing wheels 7 to rotate, thereby pulverizing the waste film.

[0029] The screening unit includes a screening plate 8, which is located between the crushing wheel 7 and the second discharge outlet 6. The screening plate 8 is higher on the left and lower on the right, and the right end of the screening plate 8 is close to the discharge outlet 4.

[0030] The return material conveying unit includes a second drive unit and a spiral auger 9. The spiral auger 9 is rotatably disposed in the return chamber. The second drive unit is connected to the spiral auger 9 to drive the spiral auger 9 to rotate. The second drive unit includes a second motor 10, which is fixedly disposed at the bottom of the housing 1 and connected to the spiral auger 9, thereby driving the spiral auger 9 to rotate.

[0031] The switching valve includes a first valve plate 11, a second valve plate 12, and a third driving member. The first valve plate 11 is movably positioned at the return port 3, and the second valve plate 12 is movably positioned at the discharge port 4. The third driving member is connected to the first valve plate 11 and the second valve plate 12 to drive them to move in opposite directions. When the first valve plate 11 moves upward, the second valve plate 12 moves downward, the return port 3 opens, and the second discharge port 6 closes; when the first valve plate 11 moves downward, the second valve plate 12 moves upward, the return port 3 closes, and the second discharge port 6 opens.

[0032] The procedure for using this device is as follows:

[0033] Waste film collected from the fields is fed into the crushing chamber through the feeding port. The crushing unit crushes the waste film blocks, which then fall onto the screening plate 8 below. Qualified waste film is filtered out and discharged from the first outlet 5 below. Because the screening plate 8 is higher on the left and lower on the right, and its right end is close to the discharge port 4, unqualified waste film flows into the return chamber through the discharge port 4 and is then transported upwards by the auger 9. At this point, the third drive unit drives the first valve plate 11 to move upwards and the second valve plate 12 to move downwards, opening the return port 3 and closing the second outlet 6. The unqualified waste film transported to the top returns to the crushing chamber through the return port 3 for a new round of crushing and screening.

[0034] By repeating the above process multiple times, the waste film can be fully crushed and screened. After the device has been running for a period of time, the third driving component drives the first valve plate 11 to move downward and the second valve plate 12 to move upward, the return port 3 closes and the second discharge port 6 opens. At this time, the unqualified waste film that still cannot pass the screening will be transported to the top by the screw conveyor 9 and discharged from the shell 1 from the second discharge port 6, thereby emptying the waste film material in the shell 1 for the next use.

[0035] Therefore, this device can perform multiple rounds of crushing and screening of waste plastic film at one time, thereby effectively improving crushing and screening efficiency and facilitating subsequent recycling and processing. By switching the two valve plates of the switching valve, the device can switch between the circulating crushing and screening mode and the final discharge mode, achieving automatic classification and discharge of qualified and unqualified waste film, and finally emptying the waste film material in the shell 1, preventing material accumulation and facilitating the next use.

[0036] In a further configuration, hoppers are installed at the feeding port and the second outlet, totaling six locations. Figure 1 As shown, the bottom wall of the crushing chamber is a sloping wall with the left side lower than the right side. The bottom of the left side wall of the crushing chamber is provided with the first row outlet 5. After the qualified waste film after screening falls onto the bottom wall of the crushing chamber, it will be automatically discharged from the first row outlet 5.

[0037] like Figure 3 andFigure 4 As shown, the third driving component includes an electric telescopic rod 13, a bracket 14, a fixed pulley 15, and a soft rope 16. The return port 3 and the discharge port 4 both extend upwards to the top of the housing 1. The electric telescopic rod 13 and the bracket 14 are both fixedly mounted on the top of the housing 1. The electric telescopic rod 13 is located directly above the first valve plate 11, and the bottom of the electric telescopic rod 13 is fixedly connected to the first valve plate 11. The bracket 14 is located between the first valve plate 11 and the second valve plate 12. The bracket 14 is equipped with a fixed pulley 15. One end of the soft rope 16 is connected to the top of the first valve plate 11, and the other end passes around the fixed pulley 15 and connects downwards to the top of the second valve plate 12. Therefore, when the electric telescopic rod 13 extends or retracts, it can drive the first valve plate 11 to move up and down. The first valve plate 11 and the second valve plate 12 are connected by a soft rope 16. When the first valve plate 11 moves downward, the soft rope 16 pulls the second valve plate 12 upward. When the first valve plate 11 moves upward, the second valve plate 12 moves downward under its own weight, thereby realizing the opposite movement of the first valve plate 11 and the second valve plate 12.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
