Oil-seepage-prevention coating device

Abstract

The invention discloses an oil-seepage-prevention coating device and relates to coating devices. The oil-seepage-prevention coating device comprises an unrolling mechanism, a preheating device, preheating rolls, a material groove, a scraping roll, a coating roll, an expanding roll, a guide roll, an oven, heating rolls, cooling rolls and a rolling mechanism. The unrolling mechanism is fixed to the ground. The preheating device is arranged behind the unrolling mechanism and connected with the unrolling mechanism. The two preheating rolls are arranged in the preheating device. The other side of the preheating device is provided with a material groove. The material groove is filled with a prepared sealant. The coating roll is arranged above the material groove. The bottom of the coating roll falls into the material groove. The scraping roll is arranged above the material groove. The expanding roll and the guide roll are arranged behind the coating roll. The oven is arranged on the right side of the guide roll. The three heating rolls are arranged in the oven. The cooling rolls are arranged behind the oven. The rolling mechanism is arranged behind the cooling rolls. The impermeable oil coating device has the beneficial effects that when glue coating is conducted, the coating amount can be controlled by adjusting pressure among the rolls, even glue coating is achieved, the coating quality is guaranteed, fastness is good after coating, and debonding is not likely to happen.

Description

technical field [0001] The invention relates to coating equipment, in particular to anti-seepage oil coating equipment. Background technique [0002] Industrial coating is to coat substrates such as paper, cloth, leather, aluminum foil, plastic film, etc. with a layer of glue, paint or ink with specific functions, and dry them for use. At present, the gluing process in many fields adopts manual operation. Because it is manual operation, the operator's operation level and experience directly affect the effect of smearing glue. [0003] The coating machine is mainly used for the surface coating process production of film, paper, etc. This machine is to coat the rolled substrate with a layer of glue, paint or ink with specific functions, and then wind it up after drying. It adopts a special multi-functional coating head, which can realize various forms of surface coating production. The winding and unwinding of the coating machine is equipped with a full-speed automatic film s...

Problems solved by technology

[0005] In the prior art, the anti-seepage oil is coated with sealant. When applying glue, there are the following problems. It is difficult to control the amount of glue applied. If too much glue is applied, the glue will overflow, which not only wastes glue but also pollutes the surface of the product. The appearance of the finished product is unqualified; too little smearing can not guarantee the sealing performance of the product, and the smearing position is difficult to grasp, which will affect the firmness and sealing of the workpiece connection, and the firmness after smearing is not enough, and it is easy to degumming
