In order to more clearly explain the present invention, Fig. 4 is referred to, without the Jing of semi-finished product 1 of PROCESS FOR TREATMENT
After crossing dilatation mold 10, inside dilatation mold due to vacuum and internal pressure in the presence of, product size occur
It is changed into the finished product 2 after expanding, now product is normally produced, and dimensionally stable, finished product 2 enters into external diameter
The light such as edge detecting sensor 30,31 regions, laser/infrared ray that radial outer edge detection sensor 30 sends
Beam 33 gets to the edge of finished product 2, formed in it is tangent, be edge that light beam just number has found finished product 2, make
Finished product 2 just blocks the light beam 33 of the transmitting of edge detecting sensor 30, and edge detecting sensor 31 sends
Light beam 34 it is parallel with light beam 33, and keep certain distance, this distance can enter according to product size or condition
Row setting.Finished product 2 is conveyed downwards under the traction of roller 50,51.Now, vacuum detecting table 60 is detected
The vacuum of product augmentation, the product air pressure in the inner gas pressure monitoring monitoring pipe of table 61.When outside finished product 2
Footpath becomes hour, and the light beam 31 of the transmitting of radial outer edge detection sensor 30 is not blocked by the edge of finished product 2,
Sensor 30 detects the external diameter of finished product 2 and diminishes, and sensor 30 sends a signal to signal processing unit
80, signal processing unit 80 sends instructions to pressure regulator valve 90 according to presupposed information, and pressure regulator valve 90 is according to finger
Automatic increase is depressed in finished product 2 in inflation for order, makes product external diameter become big, until it reaches product external diameter originally,
Finished product 2 recovers to block light beam 33.If the external diameter continuous decrease of product, the external diameter of finished product 2 cannot continue to block
During the light beam 34 that radial outer edge detection sensing 31 sends, illustrating the external diameter of finished product 2 cannot pass through pressure regulator valve 100
Pressure increase come realize external diameter adjust, now sensor 31 is signaled to signal processing unit 80, letter
Number processing unit 80 is connected to signal, while sending instructions to vacuum circuit breaker 70, cuts off the true of this production line
Empty set is united and external vacuum system, so as to realize the defencive function of vacuum system.
In sum, tube extrusion shaped device provided in an embodiment of the present invention and system can effectively nobody
The monitoring of the product such as product external diameter and vacuum, internal pressure and procedure parameter is automatically obtained under conditions of line, once and
It is that system carries out corresponding measure automatically that product occurs abnormal, on the one hand, carry out the automatic tune of relevant parameter
Section, it is ensured that the external diameter of product is returned in the range of satisfaction requirement, if there is more great exception, and adjusts
When section system cannot proceed to adjust, system automatically cuts off the vacuum of shaped device, is allowed to and external vacuum
System is effectively completely cut off, it is to avoid system vacuum is produced further to be affected, the proposition of above-mentioned technical proposal,
Can be prevented effectively from because the extremely caused product quality stability of product is poor, and wall scroll production line causes extremely
Other production lines there are chain exceptions, automatization level can be effectively improved and rate of reducing the number of rejects and seconds, improve and produce
Quality, for the product of heat-shrink tube and extrusion vacuum forming, affects significant.
Although the present invention is disclosed above with preferred embodiment, so it is not limited to the present invention, Ren Hesuo
Have usually intellectual in category technical field, it is without departing from the spirit and scope of the present invention, various when making
Change and retouching, therefore protection scope of the present invention depending on those as defined in claim when being defined.
