Description

Technical Field

[0001] This utility model belongs to the field of plastic crushing technology, and in particular relates to an energy-saving crushing device for injection molding waste. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products are typically manufactured using rubber injection molding and plastic injection molding. Injection molding can be further divided into injection compression molding and die casting. An injection molding machine is the main molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting materials using plastic molds. Injection molding is achieved through an injection molding machine and molds. During the injection molding process, a large amount of injection waste and burrs are generated. This waste consumes a significant amount of raw materials, and to save costs, it needs to be crushed and recycled.

[0003] A published patent with patent number CN209379168U discloses a device for crushing injection molding waste, including a device body, a leak-proof baffle, a storage box, a return spring, and a hinge. The device body has a feed inlet at the upper end of its front face and a feed inlet cover at the upper end of its rear face. A discharge outlet is located in the middle of its lower face. Control boxes are fixedly mounted on the lower ends of both sides of the device body, and bases are mounted on the lower ends of the control boxes. The leak-proof baffle is movably connected to both sides of the lower end face of the device body via hinges. The front face of the leak-proof baffle is fixedly mounted on both sides. The device has a handle with a fixing hole located at the upper two-thirds of the front surface. The storage box is located directly below the discharge port, and a handle is located in the middle of the front surface of the storage box. A dustproof baffle is located at the upper part of the front surface, and extension shafts are located on both sides of the upper end of the dustproof baffle. Iron rings, fixed to the upper sides of the front surface of the storage box, are fitted around the extension shafts. A strong magnet is embedded in the middle of the lower end of the front surface of the dustproof baffle. One end of a return spring is fixedly connected to the middle of the rear end of the handle, and the other end is fixedly connected to the lower end of the front surface of the main body of the device. However, this crushing device suffers from incomplete crushing, which significantly affects the recycling rate. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing an energy-saving crushing device for injection molding waste. This device performs secondary crushing of injection molding waste, thoroughly crushing it into powder, thereby improving the recycling rate and saving costs.

[0005] In view of this, the present invention provides an energy-saving crushing device for injection molding waste, characterized in that it includes a frame, on which are arranged:

[0006] A crushing mechanism, comprising a feed inlet and a discharge outlet, is used for preliminary crushing of waste materials;

[0007] A crushing mechanism is provided on the side of the crushing mechanism and is used to crush the waste material after crushing.

[0008] A transport device, one end of which is located at the discharge port of the crushing mechanism and the other end of which is located at the feed end of the crushing mechanism, is used to transport the crushed waste material inside the crushing mechanism to the inside of the crushing mechanism.

[0009] In this technical solution, the injection molding waste that needs to be crushed enters the crushing mechanism through the feed port. The waste is initially crushed in the crushing mechanism, reducing its volume. The waste is then automatically conveyed from the discharge port of the crushing mechanism to the feed end of the pulverizing mechanism by the transport device. The waste enters the pulverizing mechanism from the feed end and is thoroughly pulverized into powder. The pulverized waste can then be better recycled.

[0010] Furthermore, the crushing mechanism includes:

[0011] The feed box is fixedly mounted on the frame, and an arc-shaped cover is provided on the top of the feed box to prevent waste material entering the feed box from splashing out of the feed box;

[0012] A crushing assembly is disposed on one side of the feed box and is used to crush waste materials by crushing.

[0013] A drive assembly is fixedly disposed on the side of the feed box away from the crushing assembly, and the drive assembly is used to drive the crushing assembly to move.

[0014] Furthermore, the crushing assembly includes:

[0015] The housing is disposed on the side wall of the feed box along the length of the frame, and a crescent-shaped cutting blade is fixedly disposed at the bottom of the housing, with multiple cutting blades disposed at equal intervals inside the housing;

[0016] A rotating shaft is rotatably disposed inside the housing. The rotating shaft passes through the feed box and is connected to the drive assembly. A threaded protrusion is provided on the rotating shaft, and the threaded protrusion is disposed inside the feed box.

[0017] A compression crushing blade is fixedly mounted on a rotating shaft along the circumferential direction. There is a material passage gap between the compression crushing blade and the inner wall of the housing that is smaller than the volume of the waste material. The compression crushing blade is in the shape of an inverted triangle.

[0018] A pusher blade is spirally disposed on the outer circumferential surface of the rotating shaft. The pusher blade is disposed on one side of the compression crusher blade, and the pusher blade cooperates with the cutting blade.

[0019] In this technical solution, the drive device drives the rotating shaft to rotate. Waste fed into the feed box enters the housing under the action of the threaded protrusions. During the process of passing through the housing, the compression crushing blade and the pushing blade exert pressure on the waste, causing the waste to adhere tightly to the inner wall of the housing. The waste is crushed on the inner wall of the housing by the blades of the compression crushing blade and the pushing blade, thereby achieving compression and crushing. The pushing blade can drive the waste to move inside the housing, making the waste more thoroughly crushed. During the compression and crushing process, the cutting blade works together with the compression crushing blade and the pushing blade to compress and crush the waste, making the waste volume finer and improving work efficiency.

[0020] Furthermore, a fixed frame is provided on the frame, and the drive assembly includes a reducer and a drive power source. The reducer is fixedly connected to the rotating shaft, and the drive power source is fixedly mounted on the fixed frame. The drive power source is used to drive the rotating shaft to rotate.

[0021] In this technical solution, the driving power source can be a motor and a belt drive assembly to rotate the rotating shaft.

[0022] Furthermore, the housing is detachably connected to the feed box, and the housing includes an upper cover and a lower cover, which are bolted together.

[0023] In this technical solution, the shell and the feed box can be connected by threads to facilitate the assembly of the shell on the feed box. When cleaning or repairing the shell, the upper and lower covers connected by bolts can be separated by removing the bolts, which can facilitate cleaning and repair, greatly improving convenience and assembly.

[0024] Furthermore, a primary crushing blade and a secondary crushing blade are fixedly mounted on the rotating shaft. The primary crushing blade is located at the front end of the pusher blade, and multiple primary crushing blades are arranged circumferentially on the rotating shaft. The secondary crushing blade is located at the front end of the rotating shaft, and the blades of the primary and secondary crushing blades are toothed.

[0025] Furthermore, a compression assembly is provided on the end of the housing away from the feed box. The compression assembly is used to cooperate with the secondary crushing blade to compress and crush the waste material.

[0026] Furthermore, the compression component includes:

[0027] A top cover compression component is fixedly disposed on one side of the top cover body, and the top cover compression component is in an inclined state.

[0028] A lower cover compression component is fixedly disposed on one side of the lower cover body, and the lower cover compression component is in a horizontal state;

[0029] A hydraulic cylinder is fixed to the upper cover. The hydraulic cylinder is equipped with a hinged lifting link, one end of which is fixedly connected to the upper cover compression component.

[0030] In this technical solution, the primary and secondary crushing blades are located in the recesses inside the upper and lower cover compression components. The pusher blade brings the waste material onto the primary and secondary crushing blades. The hydraulic cylinder starts working and pushes the hinged lifting link to compress the upper cover compression component, thereby reducing the distance between the secondary crushing blade and the upper cover compression component, so that the waste material is strongly compressed and crushed into powder.

[0031] Furthermore, a cooling assembly is provided on the arc-shaped cover. The cooling assembly includes a water tank, a water pump, water pipes, and spray pipes. The water tank is located inside the frame. The water pump is fixedly located at the lower end of the frame, with one end of the water pump connected to the water tank. Multiple spray pipes are located on the arc-shaped cover, and both ends of the water pipes are fixedly connected to the water pump and the spray pipes, respectively.

[0032] In this technical solution, the water contained in the water tank is sprayed out from the nozzle through the water pipe under the action of the water pump. The water is sprayed into the inside of the feed box, so that the waste material is moist when it enters the feed box. During the crushing and pulverizing process, the high temperature generated inside the crushing mechanism will be cooled by the moisture on the waste material, preventing the high temperature from burning or melting the waste material. At the same time, it can also make the crushing mechanism operate more safely.

[0033] The beneficial effects of this utility model are:

[0034] 1. This utility model enables injection molding waste that needs to be crushed to enter the crushing mechanism through the feed inlet. The waste is initially crushed in the crushing mechanism, reducing its volume. The waste is then automatically conveyed from the discharge outlet of the crushing mechanism to the feed end of the pulverizing mechanism by a transport device. The waste enters the pulverizing mechanism from the feed end and is thoroughly pulverized into powder. The pulverized waste can then be better recycled.

[0035] 2. This utility model enables the water contained in the water tank to be sprayed out from the nozzle through the water pipe under the action of the water pump. The water is sprayed into the inside of the feed box, so that the waste material is moist when it enters the feed box. During the crushing and pulverizing process, the high temperature generated inside the crushing mechanism will be cooled by the moisture on the waste material, preventing the high temperature from burning or melting the waste material. At the same time, it can also make the crushing mechanism operate more safely. Attached Figure Description Attached image description:
