Abstract

The utility model relates to an internal cooling device of a rank type bottle-making machine, which belongs to the internal cooling device of the bottle-making machine. An internal cooling device which is composed of a cylinder cover, a cylinder, a piston, a spring and an air pipe is arranged on the lock ring of the bracket of the blow head of the rank type bottle-making machine; the internal cooling device can conduct cooling for the mould and the embryonic form of the glass bottle without generating the reheating; the life of the finished mould can be extended for one time, and the smoothness and the qualification rate can be improved.

Description

Internal cooling device of rank type bottle-making machine

The utility model belongs to bottle-making machine internal cooling mechanism.

General individual section machine is not provided with the internal cooling device at present, in becoming the positive air blowing process of mould, and compressed air, airway in the blow head support and lock ring, enter blow head, the vial blank is carried out blowing end, because of its heat is difficult to distribute, cause the vial setting slower, and causing machine operation speed low, the air pressure that enters simultaneously in the vial is very big, thereby has shortened the life-span of Cheng Mo, the influence of vial because of being reheated reduced the qualification rate of finished product.

The purpose of this utility model is to provide a kind of cooling device in glass bottle blowing machine.

The purpose of this utility model is to realize like this, one end of tracheae and the airway of blow head internal stent join, the other end and cylinder head are joined, the upper end and the cylinder head of cylinder are joined, the lower end of cylinder joins with the lock ring that is provided with ventilating pit, and piston is provided with piston ring and spring, and piston rod is provided with ventilating pit, can be corresponding with the ventilating pit of lock ring, the internal cooling pipe is equipped with in the lower end of piston rod.

The utility model is on the lock ring of existing individual section machine blow head support, an internal cooling device that is made of cylinder head, cylinder, piston, spring and tracheae is set, it can cool off mould and vial blank, can not produce after vial is formalized and reheat, machine operation speed can improve 8～10%, become the mould life-span can prolong one times, improved vial smooth finish, product qualified rate can improve 3%.

Concrete structure of the present utility model is done further narration in conjunction with the accompanying drawings.

Fig. 1 is the utility model structure iron.

One end of the airway of blow head support 4 inside and the compressed air pipe of individual section machine join, ventilating pit on the other end and the lock ring 12 communicates, can be fixed on the blow head support 4 by bolt 2 around the vent valve 3 that bolt 2 rotates, be disposed with the venting hole that several diameters do not wait by circumferential direction on the vent valve 3, venting hole communicates with lock ring 12 by the exhaust passage of blow head support 4, the airway of one end of tracheae 1 and blow head support 4 inside joins, the other end joins with cylinder head 7 by nut 5 and elbow 6, the upper end of cylinder 10 and cylinder head 7 fix by screw thread, the lower end of cylinder 10 fixes by screw thread and lock ring 12, the upper end of piston 13 is provided with piston ring 8, piston 13 is supported by spring 9, piston rod is provided with 4 ventilating pits, an internal cooling pipe 14 is installed in the lower end of piston rod, and communicate with vial, at blow head support 4 and lock ring 12 joints a rotating reversing valve 11 is set, be used for controlling air inlet or discharge directions.Principle of work, compressed air enters cylinder 10 through airway and tracheae 1 in the blow head support 4 successively, impel piston 13 descending, spring 9 is compressed, when the ventilating pit on the piston rod is relative with ventilating pit on the lock ring 12, pressurized air enters in the internal cooling pipe 14 by the ventilating pit on the piston rod, the vial blank is carried out blowing end and cooling off, blow eventually and the outside of cooled air through internal cooling pipe 14, lock ring 12, venting hole on blow head support 4 and the vent valve 3, be discharged among the atmosphere, vent valve 3 is provided with the venting hole that several diameters do not wait, needed air capacity and air pressure when blowing eventually with regulating and controlling, after finishing when just blowing, gas circuit is just closed voluntarily, piston 13 sets back under the effect of spring 9.

Claims

A kind of cooling device in glass bottle blowing machine, the end and the blow head support 4 inner airways that it is characterized in that tracheae 1 join, the other end and cylinder head 7 are joined, the upper end of cylinder 10 and cylinder head 7 are joined, its lower end joins with the lock ring 12 that is provided with ventilating pit, and piston 13 is provided with piston ring 8 and spring 9, and piston rod is provided with ventilating pit, can be corresponding with the ventilating pit of lock ring 12, internal cooling pipe 14 is equipped with in the lower end of piston rod.
