Description

Technical Field

[0001] The utility model belongs to the technical field of drying equipment, in particular to an extrusion drying equipment for synthetic leather production. Background Art

[0002] Synthetic leather refers to a plastic product that simulates the composition and structure of natural leather and can be used as a substitute material for it. Its front and back sides are very similar to leather and have a certain degree of air permeability. It is closer to natural leather than ordinary artificial leather and is widely used in the production of shoes, boots, bags, balls, etc. Existing synthetic leather generally needs to be cleaned and rolled up for use. The general structure of the existing cleaning device is to transport the synthetic leather through a cleaning box, and water nozzles are installed on the upper and lower sides of the cleaning box respectively. The upper and lower sides of the synthetic leather are cleaned by the water nozzles. The cleaned synthetic leather needs to be squeezed and drained to improve the drying efficiency. The existing cleaning and drainage are generally set separately, and no integrated structure is formed.

[0003] The Chinese invention patent with reference application number CN202110812988.1 discloses an extrusion drainage type synthetic leather cleaning device, in which the synthetic leather passes through an upper extrusion roller and a lower extrusion roller that are relatively abutted against each other, and the moisture of the synthetic leather is quickly discharged through the extrusion action of the upper extrusion roller and the lower extrusion roller, thereby improving the drying efficiency. However, in the above structure, since the upper extrusion roller uses elastic force to position the synthetic leather, only using elastic force for drainage will result in incomplete drainage, which affects the drying efficiency.
