Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a waste crushing device for injection molding. Background Technology

[0002] During the injection molding process, a certain amount of waste, such as scraps and defective products, is inevitably generated. If this waste is not effectively treated, it will not only occupy a lot of storage space, but also increase production costs and environmental burden.

[0003] To improve the efficiency and economy of waste disposal, many injection molding plants use waste crushing equipment to crush waste materials for subsequent recycling or reuse. However, most existing waste crushing equipment is open-type, which generates a lot of dust during the feeding, discharging and crushing process, polluting the working environment and even affecting the respiratory health of workers. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a waste crushing device for injection molding that effectively reduces dust and is safer and more environmentally friendly.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A waste material crushing device for injection molding includes a frame and a crushing hopper connected to the frame. The device is characterized by a dust cover closed above the crushing hopper, a feed inlet on one side of the dust cover with an openable / closable door, a vacuum cleaner on the top of the dust cover with a conveying pipe connected to it, a dust collection bag connected to the other end of the conveying pipe, a crushing mechanism in the middle of the crushing hopper, a screen below the crushing mechanism, a discharge telescopic hose below the crushing hopper, and a collection box below the discharge telescopic hose. The collection box matches the discharge telescopic hose, and the discharge telescopic hose can partially extend into the collection box.

[0007] In the above-mentioned waste crushing device for injection molding, the crushing mechanism includes crushing rollers and a driving mechanism. The crushing rollers are rotatably connected inside the crushing hopper. There are three crushing rollers, which are arranged horizontally. The driving mechanism is located outside the crushing hopper and is connected to the three crushing rollers in a transmission manner.

[0008] In the aforementioned waste crushing device for injection molding, a filter screen is installed below the vacuum cleaner.

[0009] In the above-mentioned waste crushing device for injection molding, the screen has a wavy structure and is adjacent to the three crushing rollers.

[0010] In the above-mentioned waste crushing device for injection molding, the mesh size of the filter screen is smaller than that of the sieve.

[0011] In the aforementioned waste crushing device for injection molding, wheels are provided at the bottom of the collection box.

[0012] In the aforementioned waste crushing device for injection molding, a push-pull handle is provided on the outside of the collection box.

[0013] In the aforementioned waste crushing device for injection molding, a door handle is provided on the outside of the hopper door.

[0014] In the above-mentioned waste crushing device for injection molding, the driving mechanism includes a motor, a drive gear and a driven gear. The drive gear is connected to the middle crushing roller, and the motor is driven by the drive gear. There are two driven gears, which are respectively connected to the crushing rollers on both sides and are meshed with the drive gear.

[0015] Compared with existing technologies, this waste material crushing device for injection molding processes features a dust cover above the crushing hopper to trap dust within it. A vacuum cleaner then sucks the dust from inside the dust cover upwards and transports it to a dust collection bag via a conveying pipe, effectively reducing dust emissions into the environment. This design is both environmentally friendly and safe. The filter effectively blocks larger waste fragments, preventing them from being sucked into the vacuum cleaner and damaging it, thus extending the vacuum cleaner's lifespan. The feed inlet and hopper door design on one side of the dust cover allows for easy loading of waste material into the crushing hopper by opening the hopper door and unloading it by closing the hopper door. It can prevent dust from escaping from the feed inlet. The waste material is crushed by the crushing roller in the crushing hopper. The crushed waste particles can pass through the screen and be conveyed down to the collection box through the discharge telescopic hose, which facilitates subsequent recycling and reuse. The telescopic nature of the discharge telescopic hose helps to reduce dust during the discharge process and facilitates the replacement of the collection box, further protecting the environment and personnel health and improving work efficiency. In addition, the door handle at the bin and the push-pull handle and wheels at the collection box improve the ease of operation and movement and simplify the operation process.

The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figure 1 As shown in Figure 2, this waste material crushing device for injection molding includes a frame and a crushing hopper connected to the frame. The device is characterized by a dust cover closed above the crushing hopper, an inlet on one side of the dust cover with an openable / closable door, a vacuum cleaner on the top of the dust cover with a conveying pipe connected to it, a dust collection bag at the other end of the conveying pipe, a crushing mechanism in the middle of the crushing hopper, a screen below the crushing mechanism, a discharge telescopic hose below the crushing hopper, and a collection box below the discharge telescopic hose. The collection box matches the discharge telescopic hose, and the discharge telescopic hose can partially extend into the collection box.

[0023] The crushing mechanism includes crushing rollers and a drive mechanism. The crushing rollers are rotatably connected inside the crushing hopper. There are three crushing rollers arranged horizontally. The drive mechanism is located outside the crushing hopper and is connected to the three crushing rollers in a transmission manner.

[0024] A filter screen is installed at the bottom of the vacuum cleaner.

[0025] The screen has a wavy structure and is adjacent to the three crushing rollers.

[0026] The mesh size of the filter screen is smaller than that of the sieve.

[0027] The bottom of the collection box is equipped with wheels.

[0028] The material collection box is equipped with a push-pull handle on the outside.

[0029] A door handle is provided on the outside of the warehouse door.

[0030] The drive mechanism includes a motor, a drive gear, and a driven gear. The drive gear is connected to the middle crushing roller, and the motor is driven by the drive gear. There are two driven gears, which are respectively connected to the crushing rollers on both sides and are meshed with the drive gear.

[0031] In operation, this waste material crushing device for injection molding first opens the hopper door, allowing the waste material to be crushed to be added into the crushing hopper through the feed inlet. During the feeding process, a vacuum cleaner can be activated to remove the dust generated. The filter screen effectively blocks larger waste material fragments, preventing them from being sucked into the vacuum cleaner and damaging it, thus extending its service life. After feeding is complete, the hopper door is closed, and the drive mechanism drives the crushing rollers to repeatedly crush the waste material. Dust generated during the crushing process is trapped inside the dust cover and sucked away by the vacuum cleaner. The dust sucked up by the vacuum cleaner is transported along the conveyor pipe to a dust collection bag for collection. The crushed waste particles can pass through the screen. The material falls downwards from the discharge telescopic hose into the collection box. Because the discharge telescopic hose matches and is partially embedded in the collection box, it can reduce the dust emitted into the environment during the discharge process, thereby effectively reducing environmental pollution and harm to the respiratory health of workers. It is both environmentally friendly and safe. When the collection box is full of waste particles, the crushing operation of the crushing roller is stopped, the discharge telescopic hose is retracted upwards until it is detached from the collection box, and then the collection box full of waste particles is pushed away. A new collection box is then replaced, and the discharge telescopic hose is extended downwards until it is partially embedded in the new collection box before the crushing operation can continue. The operation is convenient.

[0032] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
