Film coating machine with dust removal device

Abstract

The invention belongs to the technical field of processing of woven bags, and particularly discloses a coating machine provided with a dedusting device. The coating machine provided with the dedustingdevice comprises a machine frame. A conveying belt, a dedusting chamber and a rotating roller set are connected to the machine frame. Adsorption holes are formed in the inner wall of the dedusting chamber. The outer wall of the dedusting chamber communicates with a piston cylinder. The piston cylinder is provided with an air inlet one-way valve and an air outlet one-way valve. A first connectingrod and a second connecting rod are sequentially hinged to the other end of the piston rod. A first magnet is arranged on the piston rod. A vibrating unit comprises a spring, a second magnet, a firstsupporting rod, a second supporting rod and a lug which are sequentially connected. The first supporting rod is hinged to the second supporting rod. In the moving process of the second supporting rod,the lug can make contact with the piston cylinder. The rotating roller set comprises a driving roller, a first driven roller and a second driven roller. A coating material tank is arranged below thesecond driven roller. By adoption of the scheme, the requirement for integrated equipment for the dedusting procedure and the coating procedure in the production process of woven bags is met, and thecoating machine provided with the dedusting device is applied to a production line for processing the woven bags.

Description

technical field [0001] The invention belongs to the field of woven bag processing, and specifically discloses a film coating machine with a dust removal device. Background technique [0002] Plastic woven bags are often used in daily life. Plastic woven bags are widely used in food and chemical packaging. Food packaging requires moisture-proof and waterproof packaging. At this time, it is necessary to coat one or both sides of the woven bag with a The first layer of waterproof material is called coating film in the production process of woven bags. [0003] In order to achieve a better coating effect, the dust on the woven bag needs to be cleaned before coating. In the prior art, dust removal and film coating are often separated into two processes, and the dust removal device and film coating device used are also set separately, which leads to the fact that the woven bag may still be adsorbed during the process of being transported to the film coating equipment by the conve...

Problems solved by technology

In the prior art, dust removal and film coating are often separated into two processes, and the dust removal device and film coating device used are also set separately, which leads to the fact that the woven bag may still be adsorbed during the process of being transported to the film coating equipment by the conveyor belt after dust removal. Dust, cannot be cleaned thoroughly before coating
