Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly packaging material pre-processing technology, specifically a grinding machine for environmentally friendly packaging material pre-processing. Background Technology

[0002] Environmentally friendly packaging, also known as pollution-free packaging or environmentally friendly packaging, refers to packaging that is harmless to the ecological environment and human health, can be reused and recycled, and conforms to sustainable development. From a technical point of view, green packaging refers to an environmentally friendly type of packaging made from natural plants and related minerals that is harmless to the ecological environment and human health, is easy to recycle, is easy to degrade, and is conducive to sustainable development.

[0003] For example, Chinese patent CN211947690U discloses a grinding machine for pre-processing environmentally friendly packaging materials, including a horizontally arranged V-shaped grinding frame and a grinding belt mechanism that are closed on both sides. The top of the V-shaped grinding frame is provided with a hopper, and the bottom is provided with an outlet connected to a collection box. The belt of the grinding belt mechanism runs along the inner side of the V-shaped grinding frame under the guidance of pulleys. The inner side of the V-shaped grinding frame is provided with several teeth, and a spray box is installed on the outer side above the V-shaped grinding frame. Several spray holes connected to the spray box are provided through the V-shaped grinding frame. The belt is the same width as the inner side of the V-shaped grinding frame, and several transverse convex strips are provided on its outer side. It also includes a motor, which is connected to at least one pulley for transmission.

[0004] The aforementioned grinding mill for pre-processing environmentally friendly packaging materials still has certain shortcomings. It continuously sprays the material through spray holes, which serves two purposes: cooling and continuously adding water to facilitate grinding. Because the V-shaped grinding frame is closed on both sides, the belt is the same width as the inner side of the V-shaped grinding frame, and both the top and bottom are inclined surfaces, the material and water move along the gap between the belt and the V-shaped grinding frame, ensuring effective grinding. However, the water flow is not effectively recycled after use, increasing costs. Therefore, this application proposes a grinding mill for pre-processing environmentally friendly packaging materials to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding machine for pre-processing environmentally friendly packaging materials, comprising a support frame and a conveyor mounted on the upper surface of the support frame. The conveyor has crossbeams on its top front and rear sides, and the same grinding box is fixed on the upper surface of the two crossbeams. An elastic band adjustment device is installed and connected to the front side of the conveyor and near its left bottom. The same feed cylinder is fixed on the upper surface of the two crossbeams. An adjustment mechanism is provided inside the grinding box. A recycling mechanism is provided below the support frame. A collection box is fixed at the bottom of the support frame.

[0007] The adjustment mechanism includes an electric push rod fixed to the upper surface of the grinding box, a grinding plate fixed to the outside of the output shaft of the electric push rod, multiple grinding teeth fixed to the bottom of the grinding plate, two positioning columns fixed to the front and rear sides of the grinding plate, and a recovery port for water flow recovery opened between the collection box and the bracket.

[0009] Furthermore, two positioning grooves are provided on both the front and rear sides of the inner cavity of the grinding box, and the positioning posts on the front and rear sides slide vertically inside the positioning grooves respectively.

[0010] Furthermore, the recycling mechanism includes a water pump fixed to the front of the collection box, with a water pump end connected to a water pump pipe and a water pump end connected to a water drain pipe. A connecting plate is placed on the front of the collection box, and a filter plate for filter material is fixed on the back of the connecting plate. The water pump end is connected to a water drain pipe, and multiple horizontally arranged connecting pipes are connected to the front of the grinding box. The front ends of the multiple connecting pipes are connected to the same hollow plate.

[0011] Furthermore, a cleaning port is provided on the front side of the collection box, and a sealing gasket that seals against the inner wall of the cleaning port is wrapped around the outside of the connecting plate.

[0012] Furthermore, the end of the water pumping pipe away from the water pump is connected to the front side of the collection tank and near its bottom, and the end of the drain pipe away from the water pump is connected to the center of the front side of the hollow plate.

[0013] Furthermore, all of the aforementioned connecting pipes penetrate the front side of the grinding box and extend into its interior, and are all connected to a nozzle. A handle is fixed at the center of the front side of the connecting plate.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The grinding machine for pre-processing environmentally friendly packaging materials can be activated by an electric push rod to adjust the height of the grinding plate, and the tension of the conveyor belt can be adjusted by an elastic band adjustment device.
