Description

Technical Field

[0001] The utility model relates to the field of foam production, and more specifically, to a screening device for foam production. Background Art

[0002] Foam is a material produced by foaming plastic particles. Foam is very common in people's lives and industrial production. When producing foam, a large amount of plastic particles are needed. Before using the plastic particles, the plastic particles need to be screened. Therefore, screening equipment is needed to screen the volume of the plastic particles. When the existing screening equipment screens the plastic particles, it is necessary to use a sieve plate to screen the volume of the plastic particles through the screening structure. When the size of the screened particles needs to be changed, the sieve plate needs to be replaced. The time for manual replacement of the sieve plate is long, which increases the screening time of the plastic particles, thereby affecting the production efficiency of the foam. At the same time, due to the use of the sieve plate, the plastic particles that cannot pass through the sieve holes opened on the sieve plate will accumulate on the sieve plate, which is easy to cause the sieve plate to be blocked, thereby affecting the continued screening and affecting the screening of the plastic itself.
