Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a noise reduction mechanism for a scrap material crushing device. Background Art

[0002] Plastic products are products that are made from plastics through all processes such as injection molding or blister molding. They are a general term for daily and industrial products that are made from plastics as the main raw material. A large amount of scraps will be generated during the production process of plastic products. When factories recycle the scraps of plastic products, they need to be crushed through crushing equipment.

[0003] At present, a Chinese utility model with publication number CN217747259U discloses a scrap plastic crusher, including a chassis, a feeding pipe for feeding is arranged on the top of the chassis, two crushing rollers for crushing are arranged inside the chassis, and a screen is fixedly installed inside the chassis. In the utility model, after the plastic enters the inside of the chassis, it is crushed by the two crushing rollers, and the crushed plastic falls downward onto the air supply plate. At this time, the movably installed air supply plate is subjected to the downward pressure of the plastic, and the two springs on both sides are stretched, and the two air supply plates rotate and slide downward. Subsequently, the two movably installed air supply plates rotate and slide upward under the action of the rebound spring, thereby driving the two air supply plates to vibrate back and forth inside the chassis. When the crushed plastic leaks through the air supply hole, it will drive the air supply plate to vibrate. At this time, some plastics that are difficult to leak and are accumulated on the air supply plate will vibrate and slide down at the same time to avoid the problem that some plastics are difficult to leak and are accumulated on the air supply plate.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that although the above equipment can solve the problem that when the crushed plastic falls through the drop port, part of the plastic will fall on the air supply duct network and the air supply branch pipe and accumulate, thereby causing some plastic to be difficult to fall and affecting screening, during use, the device is not provided with a noise reduction structure. When the scraps are added to the crushing box through the feed hopper and processed, a large amount of noise will be generated and spread to the surroundings through the feed hopper, which will cause fatigue and inattention to the staff, reducing the crushing efficiency of the scraps.
