It is internal positioned at thermally conductive cover (263A).
4. a kind of working method of high stability glass reinforced plastic process units as claimed in claim 3:
Step 1, driving traction device (4) pulls glass limit to continue to transport to the direction close to traction device (4) from creel (1)
It is dynamic；
Step 2, the glass fibre on creel (1) passes through the material guiding tube (243) drawn on glassware (241) and enters in groove body (21), draws
Expects pipe (243), which slides adjustment position along slider box (242) in the process, to be made to keep uniform intervals between several glass fibres；
Step 3, glass fibre enters in liquid resin from material guiding tube (243) exit and adheres to therewith, and along roller
(25) trunking (251) on leaves liquid resin region far from the one end for drawing glassware (241) from groove body (21)；In this step mistake
Cheng Zhong, the fin (252) for connecting primary heater can be such that the vertical temperature of roller (25) surrounding subrange is increased, with this
The liquid resinous mobility in the region is improved, keeps kiss-coating more uniform；
Step 4, glass fibre enters in Glue Squeezing device (26), passes sequentially through collection bundled tube (261) and distributor plate (262) for extra tree
Rouge intercept and under, and as the hole slot distributed combination of distributor plate (262) is at the cross sectional shape of target product, the resin that is blocked
It drops into feed chute (264) and is flowed back in groove body transfer chamber (22) along channel, returned in groove body (21) after through circulator (27)；
In this step process, including thermally conductive cover (263A) shrouds collection bundled tube (261), distributor plate (262) and feed chute (264),
Guarantee fluency of the glass fibre after kiss-coating by collection bundled tube (261) and distributor plate (262) when with this, with season fall into time
The resin of hopper (264) keeps good mobility, flows back in time；Meanwhile the third heater (277) in circulator (27) is logical
The heat pipe (278) for crossing heating coil shape increases the resin temperature into groove body (21), then passes through point of deflector (274)
Stream is mixed with original resin, is evenly heated the resin in entire groove body (21)；
Step 5, it is subsequently entered in molding die (3) by the glass fibre of distributor plate (262), continues to remove a small amount of extra tree
Rouge, and it is changed into finished product after successively undergoing the preforming and forming and hardening stage, it is left under the pulling force effect of traction device (4)
Pattern has (3), and the Parts Made of Composite Glass of several fixed length is finally divided by cutting tool；
In addition, the expansion plate (281) on bubble trap (28) is in spring part during the transfer of transfer chamber (22) interior liquid resin
(282) it is close to resin liquid level under promotion always, the input end of vacuum pump (283), which passes through expansion plate (281), to float in resin
Air take out in time to the greatest extent, avoid being mixed into bladdery resin in groove body (21)；
In process of production, liquid resin can be constantly added into transfer chamber (22) by filler (221) to be converted into make up
The loss part of product；Infrared sensor (217) in groove body (21) can monitor the liquid level of resin, when liquid level is higher than in advance
If when value, overflow device (212) starts to move back and forth along guide rod (211), and road wheel (214) passes through driving gear set in operation
(213) impeller (215) rotates, and then the liquid resin in groove body (21) is transmitted back to transfer chamber (22)；In impeller (215)
While operation, fan (216) work is blown resin liquid level and is moved to overflow device (212) direction, thus by present on liquid level
Non- relieving stagnant Qi bubble discharge groove body (211), avoids subsequent glass fibre from adhering to these aeration final product qualities.
