The invention has the beneficial effects as follows that polyester packing belt form stable of the present invention is not yielding, intensity is good, long service life.
The specific embodiment
Again technological process of the present invention is specifically described below:
One, the process that polyester raw material (comprising section, bottle sheet and bottle sheet reworked material) is carried out removal moisture drying:
Take the dehumidifying of molecular sieve formula, the hot-air system drying, method is: the filled type drying.Whole dehumidification system is a sealing system, and dried polyester raw material (comprising section, bottle sheet and bottle sheet reworked material) can not contact with outside wet air.Polyester raw material (comprising section, bottle sheet and the bottle sheet reworked material) aqueous ingredients that enters extruder is controlled at less than 0.02%, and hot air temperature is at 160～180 ℃, drying time 6H.When aqueous ingredients is high in the polyester raw material (comprising section, bottle sheet and bottle sheet reworked material), can cause the violent degraded of poly-mer generation under high temperature action, make polymer molecular weight obviously descend.This apparatus structure compactness, the dehumidification rate height, water content is stable, is lower than 0.01%.
Two, polyester raw material is melt extruded (comprising section, bottle sheet and bottle sheet reworked material) process of casting sheet:
Polyester melt extrude system, be by extruder, filter and die head are formed.Each Heating Zone Temperature of extruder is wanted strict control, and temperature is crossed low can't normally extruding, and the too high product that can cause again of temperature is degraded, and each is distinguished temperature and is set at 250～275 ℃.The melt that extruder is extruded through behind the filter, through die head, through the over cooling slab roller, is cast sheet.Filter screen aperture 40-80 μ m adopts two switch types or long-acting large tracts of land type filter.Extrusion die adopts T type rack-style, and the centre is added with adjustable pad, and one pair of mould can adapt to the production of the polyester packing belt of all different sizes, and expense is extremely low, and operation is adjusted simple.
Cast chip system by slab roller, deflector roll, electrostatic adherence mechanism, cooling-water cycle mechanism forms.Also can adopt two chill rolls to carry out two-sided cooling simultaneously.The chill roll surface must have the cooling of very high degree of finish (0.2S hard chromium plating) internal water and can be cooled in 5S below 60 ℃, and to stop the sheet crystallization, the chill roll diameter is wanted 〉=100cm, and water channel is designed to the multi-head spiral water channel, to shorten water channel length.
Three, the sheet of extruding is carried out the process of at least twice stretching, also has process before each the stretching the sheet heating:
Drawing process is by first stretcher of band preheating device, Circulating Air Dry Oven, second stretcher, second Circulating Air Dry Oven, formations such as the 3rd stretcher.
First stretcher is made up of the roller of 5 ~ 7 diameters between 250 ~ 320MM.The first two roller surface is with rubber layer, and to increase friction force, 3 ~ 5 rollers in back are preheat roll, built-in cartridge type aluminium heating collar, and roller speed is 8 ~ 22 meters/minute.
The first drawing oven Circulating Air Dry Oven, thick and wide slice, thin piece here carry out stretching the first time, and draw ratio is 3.5 ~ 4.4 times, and the slice, thin piece temperature is at 90 ~ 100 ℃.
Second stretcher is made up of 5-7 roller, the roller linear velocity be 40-90 rice/minute.Second drawing oven is a Circulating Air Dry Oven, and the 3rd stretcher is made up of carrying out stretching second time through the belt of one-off drawing 5-7 roller, and draw ratio is 1.1-1.4 times, and the slice, thin piece temperature is about 110 ℃.
Three drawing mechanisms provide power by the frequency conversion reductor, and three machines interlocks is adjustable, keep low speed speed ratio between three stretchers when high-speed cruising to remain unchanged.
Four, the process that the belt after stretching is carried out embossing:
Embossing device carries out embossing to the belt that needs embossing, is driven by torque motor, and a pair of knurling rolls can be adjusted pressure, uses the spring floating pinch device.
Five, tempering thermal finalization process:
The tempering setting temperature is 160 ℃-250 ℃, adopts Circulating Air Dry Oven.
Six, cooling and shaping process:
Cooling and shaping adopts the air natural cooling, and belt is reduced to room temperature before arriving rolling, takes the natural cooling roller (driven voller) of multiple tracks arrangement up and down.
Seven, wrapup procedure:
Well-regulated volume is arranged in the harvest of finished product belt, required inside and outside rolling tension force to be consistent, flat appearance reduces the belt distortion as far as possible, produces distortion, does not allow with one deck and rides zoning, must guarantee the volume that do not loose before the user uses.
