Description

System at composite plastic hard coiled material automation dip-coating table

Technical field

Device at a kind of composite plastic hard coiled material automation dip-coating table is the utility model is related to, more particularly to it is a kind of automatic Controlling extent height, high quality, high yield, high efficiency, low cost, safe and environment-friendly composite plastic hard coiled material surface apply polyester Device at the innovative technology dip-coating table of glue processing.Belong to new material manufacturing technology field.

Background technology

China's composite plastic hard coiled material industrial technology is highly developed at present, and wherein hard coiled material, sheet surface apply Polyester adhesive and hardness, finish, brightness and the mould proof antifouling fire prevention processing of increase are composite hard coiled material sheet productions During very important technology process, the cost and physicochemical property and outward appearance for directly affecting composite plastic hard coiled material refer to Mark.The outer composite plastic hard coiled material surface of Now Domestic applies polyester adhesive and typically uses exploitation formula reticulate pattern roller coat, cutter painting, spray, smear The conventional one side coating processes such as painting, it is small in the presence of thickness scope is applied, and can only once apply one side, the uneven easily holiday of coating, drag Silk, blade coating, difference is big before and after regulation, poor appearance, quality are unstable, and operation difficulty is big, operation is random big, labor intensity Greatly, solvent is high in working environment air and environment is poor, and operational danger is big, low production efficiency, yields poorly, raw and auxiliary material into This and integrated cost are high.The quality of gluing each operation changes with manual operation and the change of environment, due to solvent-free recovery Device and unordered exclusion is placed on working environment space, all working key element is in not awarding control or artificial free state of a control, from And seriously constrain the processing procedure control ability of coating process technology.Due to composite plastic hard coiled material generally apply polyester adhesive with The compound concentration of glue, temperature, time, closed state, flowing liquid, and coiled material tension, charge level temperature, humidity, coating Speed, scraper pressure, scraper hardness, scraper cutting edge mouth, anilox roll width of mesh, the depth, mesh depth consistent degree, block clear Wash, spray muzzle pressure, impurity block, each procedure pressure, temperature with operating ambient temperature humidity etc. it is a series of change and Nonstandard and uncertain factor causes to apply the difficult control of polyester adhesive quality, ultimately causes composite plastic hard coiled material and applies polyester adhesive effect Bad, of low quality, operating efficiency is low, yields poorly, feed consumption height, and defect rate is high, and cost is high, and operation staff labor intensity is big, work It is poor to make environment, it is dangerous.During using original polyester adhesive technology, glue is often tested for make painting thickness consistent etc. up to standard Liquid concentration, solvent is added, adjust scraper distance and pressure, exchanged tool section, cleaning anilox roller, open up anilox roll again, add glue Liquid, tension, speed, temperature are adjusted, but still cannot ensure to eradicate all problems of coating each operation, also therefore due to often adjusting Section, exchange and cause defect rate high, it is big to cause to adjust front and rear difference, causes machine stop times to increase, and not only range of coat thicknesses is small, One side can only be once applied, and quality cannot be guaranteed, and yield is impacted, and operating efficiency is low, and cost is high, also labor intensity Greatly, working environment is poor, and security risk is high.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of brand-new painting polyester adhesive for above-mentioned prior art Novel technique --- dip coating apparatus.The utility model dipping process technique device can thoroughly solve tradition and apply polyester adhesive process skill Shortcoming and defect existing for art, so as to can once complete double spread, it is thick to applying polyester adhesive also to improve composite plastic hard coiled material Spend expanded scope and coating uniform, bright and clean brightness, scar, drag silk, holiday, paragraph difference, it is glue jail peel strength, mould proof anti- The every physical and chemical indexs and appearance index such as dirty, fire prevention.Also greatly improve and improved after applying polyester adhesive pipeline automation degree Operating efficiency, production yields is improved, reduce labor intensity, improve circumstance, it is ensured that safety of employees.This practicality is new Type reduces after implementing applies polyester adhesive cost more than 45%, reduces defect ware more than 15%, improves nearly two times of operating efficiency, every stream Waterline saves employee 3, improves 2.2 times of yield, and recycling design reusability water reusability 100%, is operated in live air up to 95% Solvent strength is greatly reduced 97%, and environment is greatly improved, and operation industrial accident rates decline 85%, and safety of employees obtains really It is real to ensure.

The technical scheme in the invention for solving the above technical problem is：A kind of composite plastic hard coiled material automation leaching System at table is applied, it mainly includes discharging device, tension device, heater, dip-coating glue groove, device at table, cooling device, right Side tension device and wrap-up, material volume through discharging device come out after through tension device, by charge level in the presence of heater It is heated to initially plastifying phase state, the charge level come out by tension device is delivered to dip-coating glue groove, coated polyester glue by deflector roll Wet feed face connected through vertical defeated reach of deflector roll into solvent heat volatilization device, solvent heat volatilization device bottom by pipeline and solvent recovery tower Logical, centre installation high-speed fan pumps the solvent waste gas that hot volatilization device volatilizes to solvent recovery tower；The coating charge level Vapor away in glue-line to enter after solvent through solvent heat volatilization device and include device at the table of mirror roller and silica gel roller, through mirror roller with It is press-formed in silica gel roller operating and tentatively cools down；The charge level handled through device at table conveys cooling device by deflector roll, passes through Charge level after cooling and shaping enters the wrap-up progress big volume of harvest after entering opposite side tension device.

Preferably, the bottom of the solvent recovery tower is provided with the high-pressure electrostatic solvent recovery for removing most of solvent waste gas Device, it is provided with spaced arrangement from down to up in the solvent recovery tower, the water for reclaiming remainder of exhaust gas drenches passage And exhaust steam passage, the exhaust steam passage to tower top are merged into exhaust emissions passage, in the high-pressure electrostatic solvent recovery unit Bottom is provided with recycling design storage bucket, and picks and places autocontrol valve equipped with solvent, and cooling water is taken out by high-pressure hydraulic pump from tank Be fed into water supply pipeline, then separately flow into water leaching passage, to tower bottom after tail water collect and carried out into water-cooling apparatus by setting Constant temperature degree cools down, and water after cooling flows into tank reuse after water filtration filtering sand tank falls impurity again.
