[0021] Embodiment

[0022] As Figure 1 shown, the waste recycling device of the biodegradable plastic bag making machine includes a waste bin 7 and an extrusion device arranged above the waste bin 7. The extrusion device includes a pressing plate 13, and a hydraulic rod 1 providing power is arranged above the pressing plate 13. The hydraulic rod 1 can drive the pressing plate 13 to move up and down, so as to press the plastic bag waste into blocks. The hydraulic rod 1 is arranged on a cross plate 2, and brackets 3 for support are arranged at both ends of the cross plate 2. The waste bin 7 includes a bottom plate 24 and side plates. The side plates are vertically arranged with the floor. A guard plate 5 is arranged above the waste bin 7. An extrusion plate 11 is arranged at the center of the guard plate 5. The bottom of the bracket 3 is fixedly arranged on the surface of the guard plate 5.

[0023] As Figure 1 and Figure 4 shown, the side plates include a left wall plate 14 and a right wall plate 22. The left wall plate 14 and the right wall plate 22 are oppositely arranged on the left and right sides of the bottom plate 24. The upper end of the left wall plate 14 is connected to the guard plate 5, and the lower end of the left wall plate 14 is connected to the bottom plate 24. The left wall plate 14 is fixedly arranged on the left side of the waste bin 7. A lock 4 is arranged at the upper end of the right wall plate 22. The lock 4 passes through the upper surface of the guard plate 5. The lower end of the right wall plate 22 is rotatably arranged with the bottom plate 24. The lower end of the right wall plate 22 is hinged to the bottom plate 24, and the upper end of the right wall plate 22 is fixed by the lock 4. After extrusion, the right wall plate 22 can be opened to take out the waste pressed into blocks.

[0024] As Figure 1 and Figure 4As shown, annular air vents 9 and circular air vents 10 for exhaust are provided on the surfaces of the left wall panel 14 and the right wall panel 22. A waste inlet 12 is provided at the center of the annular air vent 9 of the left wall panel 14, and a handle 23 is provided at the center of the annular air vent 9 of the right wall panel 22. By pulling the handle 23, the right wall panel 22 is opened, and the waste pressed into blocks is taken out.

[0025] As Figure 4 shown, the waste inlet 12 is connected to a conveying pipe 21, and a blower 20 is provided on the conveying pipe 21. The blower 20 creates a negative pressure inside the conveying pipe 21, sucking the plastic bag waste into the waste bin 7.

[0026] As Figure 1 shown, the side plate further includes a front wall panel 15 and a rear wall panel, and strip-shaped air vents 8 for exhaust are provided on the surfaces of the front wall panel 15 and the rear wall panel.

[0027] The annular air vents 9, the circular air vents 10 and the strip-shaped air vents 8 are all for facilitating the discharge of the gas inside the waste bin 7 during extrusion, making the extrusion effect better.

[0028] As Figure 1 shown, a rubber strip 6 is provided at the gap between the extrusion plate 11 and the guard plate 5. The rubber strip 6 can prevent the plastic bag waste from flying out through the gap of the extrusion plate 11, and circular air vents 10 are provided on the surface of the extrusion plate 11.

[0029] As Figure 2 and Figure 3 shown, sliding blocks 16 are provided at both ends of the extrusion plate 11, and sliding grooves 19 are provided on the side wall of the waste bin 7. The sliding blocks 16 are adapted to the sliding grooves 19. The extrusion plate 11 is slidably arranged on the waste bin 7 through the sliding blocks 16 and the sliding grooves 19. A spring 17 is provided below the sliding block 16. One end of the spring 17 is connected to the sliding block 16, and the other end of the spring 17 is connected to the bottom surface of the sliding groove 19. A buffer pad 18 is provided on the upper surface inside the sliding groove 19. After extrusion is completed, the extrusion plate 11 is reset under the action of the spring 17.

[0030] During use, the blower 20 creates a negative pressure inside the conveying pipe 21, sucking the plastic bag waste into the waste bin 7. The hydraulic rod 1 drives the pressing plate 13 to move up and down. The pressing plate 13 presses on the surface of the extrusion plate 11, pressing the waste inside the waste bin 7 into blocks. The annular air vents 9, the circular air vents 10 and the strip-shaped air vents 8 discharge the gas inside the waste bin 7 during extrusion, making the extrusion effect better. After extrusion is completed, the waste pressed into blocks is taken out through the right wall panel 22.

[0031] Through extrusion, the present invention makes the fluffy waste become blocks, which not only solves the problem that fluffy waste is not easy to collect, but also reduces the occupied volume of the waste, enables the waste bin to collect more waste, and improves the practicability.

[0032] Therefore, the waste recycling device of the biodegradable plastic bag making machine with the above structure is adopted in the present utility model. The plastic bag waste is collected through the waste box, and then through extrusion, the fluffy waste is turned into blocks, solving the problems that the waste recycling device of the existing bag making machine is small in volume and it is not easy to collect the fluffy waste.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present utility model, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present utility model.
