Description

Technical Field

[0001] The utility model relates to the technical field of cardboard production equipment, in particular to a negative pressure type PVC raw material conveyor. Background Art

[0002] Cardboard is the main raw material for making bank cards, subway cards, SIM cards and other cards. Cards are formed by stacking and pressing individual cardboards. The raw materials for making cardboard include polyvinyl chloride resin, colorants and additives.

[0003] When preparing cardboard, the bagged polyvinyl chloride resin raw material needs to be transported to the preparation equipment first. The existing conveying equipment is commonly used as a negative pressure conveyor, which extracts the polyvinyl chloride resin raw material under negative pressure through the principle of negative pressure;

[0004] The existing negative pressure conveyor still has defects during operation:

[0005] 1. The negative pressure conveyor has a relatively simple operating performance. When too much raw material is injected, it will cause the raw material to accumulate in the conveyor, and even block the negative pressure channel, affecting the normal conveying operation;

[0006] 2. During the transportation of raw materials, some of the raw materials will clump, making it difficult for the negative pressure of the negative pressure conveyor to extract them, causing them to accumulate at the bottom of the negative pressure conveyor, affecting subsequent transportation operations;

[0007] Therefore, the present application proposes a negative pressure PVC raw material conveyor. Utility Model Content
