Description

Technical Field

[0001] The utility model belongs to the technical field of material suction devices, and particularly relates to a vacuum suction hopper for modified plastic particles. Background Art

[0002] At present, in the production and processing of plastic particles, it is necessary to quickly transport plastic particles between different processes. In the prior art, a vacuum suction machine is generally used to suck plastic particles. A vacuum suction machine (also known as: vacuum loader, vacuum conveyor, vacuum feeder, dry powder suction machine, etc.) is a pipeline-type feeding device that transports powdery materials and granular materials through vacuum suction to achieve dust-free and sealed transportation. By using the air pressure difference between the vacuum and the ambient space, the gas flow in the transportation pipeline is formed, so that the powdery materials and granular materials move, achieving the effect of quickly transporting plastic particles.

[0003] However, when the existing plastic particle suction machine transports plastic particles, due to the high insulation of plastic products, static electricity is easily accumulated between plastic particles. In the process of processing plastic particles, static electricity is a problem that cannot be ignored. The accumulation of static electricity will not only cause plastic particles to adsorb dust, affecting product quality, but also may pose a safety hazard to production equipment and operators. Especially when using equipment such as a suction machine to transport and process plastic particles, if there is no effective anti-static measure, static electricity will cause plastic particles to stick together, affecting the transportation efficiency of plastic particles. In severe cases, it will block the discharge port, causing equipment failure, and even causing electric shock to operators.

[0004] Therefore, the present application provides a vacuum suction hopper for modified plastic particles, aiming to solve the problem that plastic particles are easily adsorbed on the side wall of the suction hopper, affecting the transportation efficiency of plastic particles.

[0053] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the creative concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
