Description

Film blowing machine

Technical Field

The utility model relates to a film processing equipment field, in particular to film blowing machine.

Background

Among the prior art, film blowing machine is when the blown film, and the gaseous volume in the membrane bubble is the key factor of deciding the membrane bubble size, and the tolerance is too much, and the too big dilatational strain of membrane bubble, tolerance are low excessively, and the shrink of membrane bubble undersize is shriveled, all very big influence product quality, and prior art all is manual regulation control, adjusts untimely and the precision is low, extravagant manpower, influences product quality.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art's defect, provide a film blowing machine, simple structure, rationally distributed, ingenious utilization is aerifyd and is deflated keep dynamic balance, makes the membrane bubble maintain a stable size, has promoted product quality.

The technical scheme of the utility model:

the utility model provides a film blowing machine, contains frame and die head, and blowing machine is at the during operation, and the suspension has cylindrical membrane bubble on the die head, and on the die head to the gas tube of aerifing in the membrane bubble and the gassing of gassing, be equipped with inflation solenoid valve and gassing solenoid valve on gas tube and the gassing pipe respectively, on inflation solenoid valve and the gassing solenoid valve inserted two output circuit of relay respectively, the access has laser sensor on the input circuit of relay, laser sensor comprises transmitter and receiver, transmitter and receiver set up in the both sides of membrane bubble, the laser line of transmitter and receiver after focusing is tangent with the outer wall of membrane bubble.

Furthermore, a cooling water ring is arranged below the die head, cylindrical water ring cloth is arranged below the water ring, the film bubble is located in the water ring cloth, the diameter of the water ring cloth is equal to that of the film bubble, and a barrel opening at the bottom end of the water ring cloth is of an even sawtooth structure.

Further, the laser sensors are arranged on two sides of the film bubble below the water ring cloth.

Further, the relay is of the type RJ 2S-CL-D24.

Further, the laser sensor model is JT31-5 MNO.

Furthermore, the transmitter and the receiver are installed at the bottom of the hanging rod through a universal joint, and the hanging rod is installed on the rack.

Compared with the prior art, the utility model discloses a set up laser sensor's transmitter and receiver in membrane bubble both sides, and make the laser line tangent with the membrane bubble outer wall after focusing, in the blowing process, the interior gas quantity of membrane bubble is too sufficient, then the membrane bubble inflation, the receiver can not receive laser, laser sensor transmits voltage signal gives the relay, the relay carries out to open the gassing solenoid valve and closes the gassing solenoid valve, unnecessary gas outgoing in the membrane bubble this moment, the membrane bubble diameter reduces, when the receiver receives the laser that the transmitter sent, transmit voltage signal to the relay, relay switching circuit, carry out to open the gassing solenoid valve and close the gassing solenoid valve, inflate in the membrane bubble this moment, so circulation is reciprocal, reach a dynamic balance, make the diameter of membrane bubble maintain throughout with the tangent size of laser line, compared with the prior art, have characteristics such as timeliness and stability, the diameter fluctuation of the film bubble is small, and the product quality is stable; the water ring and the water ring cloth are designed, and the water ring cloth wraps the film bubble and rapidly cools the film bubble, so that the size of the film bubble is stabilized, and the product quality is improved; the arrangement of the universal joint is beneficial to the focusing and installation of the transmitter and the receiver. The utility model discloses structural design is ingenious, does benefit to and aerifys and the dynamic balance of keeping of gassing, makes the membrane bubble maintain a stable size, has promoted product quality.
