Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical equipment technical field, especially a kind of waste bag processing waste recovery device. BACKGROUND

[0002] The film blowing machine is used to melt plastic particles into thin film. In the production process of plastic film, polyethylene particles are first transported to the melting furnace by the feeding device for high-temperature melting. Then, the molten polyethylene material is filtered to remove impurities by the film blowing machine head, and then comes out of the die port of the die head. After cooling and blowing by the air ring, it is conveyed to the cutting device by the herringbone plate traction roller on the bubble stabilizing frame for cutting. The cut plastic film is then conveyed to the winding device for winding, so that the finished film is wound into a cylinder. However, the waste material belt cannot be utilized, which causes resource waste and environmental pollution. In addition, a large number of defective waste bags are produced during the production process of waste bags. To reduce the production cost of waste bags, waste material and defective waste bags need to be recycled accordingly.

[0003] The Chinese utility model patent (authorized announcement number: CN217249256U, name: a waste bag processing waste recovery device) includes a crushing bin, a collection bin is fixedly installed on the bottom surface of the crushing bin, two crushing rollers are arranged inside the crushing bin, rotating openings are respectively formed on the two sides of the crushing bin, the crushing rollers are movably connected with the rotating openings, two first driving motors are fixedly installed on one side of the crushing bin, a PLC controller is fixedly installed on one side of the collection bin, the cover is provided, the worker can open the cover, the first driving motor, the second driving motor, the rotating rod and the crushing roller are used cooperatively, so that the waste bag is curled on the outer cylindrical surface of the rotating rod. Under the action of the threaded hole, the rotating rod rotates and moves linearly, so that the waste bag continuously contacts the crushing roller, and the waste bag is crushed more thoroughly, avoiding the winding of the waste bag on the crushing roller, which reduces the crushing efficiency. However, the coarse particle size of the screened residue needs to be manually operated to enter the crushing bin for re-crushing, which increases the labor intensity of the workers. SUMMARY

[0023] like Figures 1-3 As shown, a waste recycling device for garbage bag processing includes a vertical cylinder 1. A main shaft 2 is installed inside the cylinder 1, and a crushing blade 3 is fixed on the main shaft 2. A screening box 4 is installed at the discharge port of the cylinder 1. The screening box 4 has two discharge ports: one at the bottom of the screening box 4 and the other on the side wall. A screen plate 5 is also installed inside the screening box 4. Coarse material is guided through the screen plate 5 to the discharge port on the side wall, while fine material is guided through the screen plate 5 to the discharge port at the bottom of the box. A collection box 6 is fixed on the top, and the collection box 6 is connected to the screening box 4 through the discharge port on the side wall of the screening box 4. A screw conveyor 7 is also installed on the collection box 6. The screw conveyor 7 is used to transport the material in the collection box 6 to the feed port of the cylinder 1. Through the reasonable structural design and the collection box 6 with screw conveyor 7, the coarse-sized crushed material after screening can continuously enter the cylinder 1 for further crushing, which reduces the labor intensity of workers and allows the machine to operate without stopping, thus improving the working efficiency of the device.

[0024] In this embodiment, as Figure 2 and 4 As shown, the screen plate 5 is hinged inside the screen box 4. A connecting rod 8 is hinged to the screen plate 5 away from its pivot. A driven shaft 9 is rotatably installed on the top inner wall of the screen box 4. The driven shaft 9 is linked to the main shaft 2 through a pair of bevel gears. A turntable 10 is fixed to the end of the driven shaft 9 away from the bevel gears. The turntable 10 is hinged to the connecting rod 8 away from the center, which realizes the linkage between the screen plate 5 and the crushing blade 3, avoids the need to install an additional vibration motor, and reduces the production and use cost of this device.

[0025] In this embodiment, as Figure 2 and 3 As shown, a pair of baffles 11 are fixed on the sieve plate 5. The pair of baffles 11 are located on both sides of the sieve plate 5 in the sieve direction. The distance between the pair of baffles 11 near the discharge port on the side wall of the sieve box 4 gradually decreases, so that all the coarse particles after screening enter the collection box 6, avoiding the mixing of materials that fall into the discharge port at the bottom of the sieve box 4.

[0026] In this embodiment, as Figures 1-3As shown, the discharge port at the bottom of the screening box 4 is formed by the convergence of four inclined surfaces, which facilitates the rapid discharge of small-diameter fragments from the crushing box and prevents them from remaining at the bottom of the box.

[0027] In this embodiment, as Figure 2 and 4 As shown, a row of through holes 12 is opened on the turntable 10 along its radial direction. The connecting rod 8 is connected to one of the through holes 12 by a pin. By connecting the connecting rod 8 to different through holes 12, the vibration amplitude of the screen plate 5 can be adjusted.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
