Description

Technical Field

[0001] This utility model relates to the field of granulator technology, specifically a protective film recycling energy-saving and environmentally friendly granulator. Background Technology

[0002] Waste plastic film is a type of plastic waste. "Waste plastic" is a common term and doesn't necessarily refer to discarded, old, or useless plastic products. The vast majority of plastic products, especially those used in large quantities for single purposes, do not undergo significant changes in the properties of the plastic material itself after use. Therefore, they can be completely recycled and reprocessed into new plastic products for reuse.

[0003] When recycling plastic film, the plastic needs to be heated and liquefied before being granulated using a granulator. Common granulators are equipped with heating modules to prevent the plastic from solidifying prematurely and sticking to the rotating shaft. However, after granulation, the cooling time is too long, making the plastic prone to sticking to the receiving bin and difficult to handle. Therefore, those skilled in the art have provided an energy-saving and environmentally friendly granulator for plastic film recycling to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving and environmentally friendly granulation machine for recycling protective films, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An energy-saving and environmentally friendly granulation machine for recycling protective films includes a granulation cylinder, an air conditioner, a glue inlet, a rotating shaft, and a material bin. The bottom of the granulation cylinder is fixed to a support plate, and the left and right ends of the support plate are fixedly connected to a left support leg and a right support leg, respectively. The rotating shaft is located inside the granulation cylinder and is rotatably connected. A spiral blade is provided on the rotating shaft. A driven wheel is fixedly connected to the right side of the rotating shaft. A motor is fixedly installed inside the right support leg, and the right side of the motor is connected to a driving wheel. The driven wheel is connected to the driving wheel via a belt. A glue inlet is provided on the top right side of the granulation cylinder. Several granulation holes are provided on the lower left side wall of the granulation cylinder. An air conditioner is fixedly installed on the top left side of the granulation cylinder. The top of the air conditioner is connected to the right side of the rotating shaft via an air inlet pipe, and the left side of the air conditioner is connected to the left side of the rotating shaft via an air outlet pipe. A receiving hopper is fixedly installed on the right side of the left support leg. A cold air hole is provided inside the receiving hopper. The front and rear sides of the air conditioner are connected to the cold air hole via cold air pipes. The right end of the receiving hopper is fixedly connected to the upper left end of the material bin.

[0008] As a further improvement of this utility model, the connection method between the air outlet pipe and the rotating shaft is the same as the connection method between the air inlet pipe and the rotating shaft.

[0009] As a further improvement of this utility model, a sealing ring is provided at the connection between the rotating shaft and the granulation cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This equipment is equipped with an air conditioner, which can raise the temperature of the rotating shaft and prevent the plastic molten plastic from cooling and solidifying too early and sticking to the rotating shaft. The receiving hopper is connected to the cold air end of the air conditioner. After the plastic particles fall into the receiving hopper, they can be cooled quickly. Both the hot air end and the cold air end of the air conditioner can be effectively utilized, improving energy utilization. Attached Figure Description
