Abstract
The utility model relates to a die head outlet clearance automatic adjusting device of a plastic film blowing machine, which is characterized in that the outer edge of a ring-shaped discharge hole (1) surrounded the die head is uniformly equipped with a plurality of metal adjusting bars (2), one end of each adjusting bar (2) touches the outer edge of the discharge hole (1) and is perpendicular to the tangential line of the top-touching point of the outer edge, the other end is fixed on a fixing ring (3), all the adjusting bars (2) are internally equipped with heaters (4), and the heaters (4) are connected with a computer which is connected with a plastic film-thickness sensor. The above structure can real-time correct the abnormal change of the thickness of the film bubble generating partial position through automatically and partially changing the temperature of the specific position of the outlet of the die head, thereby increasing the quality of products.
Description
Technical field:
The utility model relates to a kind of plastic film blowing machine die head exit gap self-checking device
Background technology:
Traditional a kind of plastic film blowing machine die head exit gap does not have self-checking device, therefore, in the blowing process, can not in time obtain when the thickness error of plastic foil is against regulation correcting.
Summary of the invention:
The purpose of this utility model is: be implemented in the process of blown film, can correct the against regulation variation of thickness of plastic foil in real time.
The utility model provides: a kind of plastic film blowing machine die head exit gap self-checking device, it is characterized in that: evenly be provided with number of metal regulating rod (2) around die head ring-type discharging opening (1) outer rim, regulating rod (2) one ends top is bumped discharging opening (1) outer rim and is bumped a tangent line perpendicular to the outer rim top, and the other end is fixed in retainer ring (3); Heating element (4) is housed in the regulating rod (2), and heating element (4) connects with the computer that is connected the plastic foil thickness transducer.When certain thickness transducer detects the improper change of thickness generation of its present position film bubble, in real time the electronic signal that changes is passed to computer, heating element (4) work of computer control correspondence position, make regulating rod (2) expanded by heating, ring (3) is fixing because the one end is fixed, so, inevitable roof pressure ring-type discharging opening (1) outer rim of its other end, make it be out of shape to the center of annular discharging opening (1) indent, cause this place's outlet gap to narrow down, cause discharging to reduce, cause film to steep this place's thickness and reduce, correct the improper change of film bubble thickness with this.
Effect of the present utility model: said structure can be corrected the improper change that film steeps the thickness of the local location that takes place in real time by the automatic local size that changes die head ad-hoc location outlet gap, thereby improves the quality of product.
Description of drawings:
Fig. 1, a kind of structural representation of the utility model.
Embodiment:
Embodiment 1, see Fig. 1, around die head ring-type discharging opening (1) [being outlet gap], outer rim evenly is provided with number of metal regulating rod (2), regulating rod (2) one ends top is bumped discharging opening (1) outer rim and is bumped a tangent line perpendicular to the outer rim top, and the other end is fixed in retainer ring (3); Heating element (4) is housed in the regulating rod (2), and heating element (4) connects with the computer that is connected the plastic foil thickness transducer.
