Description

Technical Field

[0001] The utility model relates to the technical field of plastic film processing, in particular to a device for recycling scraps of a film blowing machine. Background Art

[0002] The film blowing machine is a machine that produces plastic film by blow molding. It mainly squeezes the plastic into a thin tube, then blows up the plastic with compressed air while it is hot, and then cools and shapes it to obtain a tubular film product. The performance of this film is between oriented film and cast film. After the film blowing machine is completed, it will be cut, and the excess scraps will be recycled through a recycling device to avoid scraps from polluting the environment and reduce waste.

[0003] A device for recovering waste edges of a film blowing machine with application number 202221762401.7 is disclosed. The utility model provides a winding drum capable of fixing the ends of the waste edges and an electric motor capable of driving the winding drum to rotate through a reduction gear box, so that the waste edges can be wound around the outside of the winding drum driven by the rotating winding drum, thereby enabling the waste edges to be recovered in a centralized manner, thereby avoiding danger caused by random placement of the waste edges.

[0004] However, the plastic film scraps after cutting are long and thin. When the long and thin plastic film scraps are recycled by rolling them up, the scraps are easily stretched by force, causing them to sag and entangled around. In severe cases, the plastic film scraps may break and require staff to re-pull them. Subsequently, the rolled-up scraps must be disassembled and taken out, which is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a film blowing machine scrap recycling device to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for recycling scraps of a film blowing machine, comprising a device main body, a recycling component is arranged inside the device main body, and the recycling component comprises a water cooling tank, a recycling tank and a discharge tank, a hydraulic cylinder is installed inside the recycling tank, and the output end of the hydraulic cylinder is connected to a press frame through a piston rod, a second heater is installed inside the press frame, a first heater is installed on the inner wall of the recycling tank, a water cooling pipe is connected between the water cooling tank and the recycling tank and the discharge tank, a semiconductor refrigerator is installed above the water cooling tank, and a heat conducting plate is connected to the bottom of the semiconductor refrigerator, a heat sink is connected to the top of the semiconductor refrigerator, a second motor is installed on the outer surface of the device main body, and a stirring frame is connected to the output end of the second motor, and a blade is sleeved on the outside of the stirring frame.

[0007] By adopting the above technical scheme, the device is arranged below the cutting mechanism, and the scraps produced by cutting are directly affected by gravity and fall into the recovery tank. When the recovery tank is full, the scraps are melted by the first heater and the second heater, and the hydraulic cylinder drives the pressure frame to move so that the melted scraps are squeezed into the water cooling pipe. The water in the water cooling tank and the water cooling pipe conduct heat to solidify the melted scraps into slender plastic rods. After the motor is started, the output end drives the blade and the stirring frame to rotate, and the slender plastic rods are pelletized by the rotation of the blade, so that the recycled plastic film scraps are made into plastic pellets for direct recycling for re-blowing the film.

[0016] Furthermore, a collection hopper is connected to the top of the device body, and a collection box is placed below the outer surface of the device body.

[0017] By adopting the above technical solution, the device is arranged below the cutting mechanism, and the scraps produced by cutting fall directly into the recovery trough under the influence of gravity, and the plastic particles fall through the discharge trough and are guided into the collection box for unified processing by the staff.

[0018] Furthermore, the discharge trough is located above the collecting box.

At the same time, the plastic film scraps can be transported by falling between the two conveying rollers under the influence of gravity, avoiding the plastic film scraps from being unable to be powered by the conveying rollers after breaking. At the same time, the scraper is used to prevent the plastic film scraps from sticking to the surface of the conveying roller, and the static electricity on the conveying roller and the scraper is conducted away by the grounding plate to prevent the plastic film scraps from being adsorbed on the conveying roller and the scraper due to static electricity.

[0022] Furthermore, the gear, conveying roller, scraper and grounding plate are each provided with two, and the two scrapers and grounding plates are arranged in mirror image.

[0023] By adopting the above technical solution, the output end of the first motor drives the two conveying rollers to mesh through the meshing of two gears, so as to apply a certain power to the plastic film scraps and reduce the residue on the collection bucket.

The scraps are melted by the first heater 911 and the second heater 912; the water cooling pipe 908 is connected between the water cooling tank 905 and the recovery tank 913 and the discharge tank 914. The water cooling pipe 908 is made of aluminum alloy material.

At the same time, the semiconductor refrigerator 902 is started to perform heat exchange. At this time, the semiconductor refrigerator 902 uses the heat conducting sheet 904 to cooperate with the water flow generated by the stirring frame 907, so that the temperature in the water flow is absorbed by the semiconductor refrigerator 902, and at the same time, the heat in the semiconductor refrigerator 902 is dissipated to the outside through the heat sink 903.

At the same time, the plastic film scraps can be affected by gravity and fall between the two conveying rollers 5 to be conveyed, so as to avoid that the plastic film scraps cannot be applied with power by the conveying rollers 5 after they are broken. At the same time, the scraper 6 is used to prevent the plastic film scraps from adhering to the surface of the conveying roller 5, and the static electricity on the conveying roller 5 and the scraper 6 is guided away by the grounding plate 7 to prevent the plastic film scraps from being adsorbed on the conveying roller 5 and the scraper 6 due to static electricity.

At the same time, the stirring frame 907 rotates to make the water in the water cooling tank 905 flow, thereby accelerating the cooling efficiency. After that, the plastic particles fall through the discharge trough 914 and fall into the collection box 8 for unified processing by the staff;
