Abstract

The utility model discloses a blowing head of a bottom-making machine. The blowing head comprises a blowing head body, wherein an air inlet pipe is arranged vertically at the centre of the blowing head body, a blowing pipe is arranged inside the air inlet pipe, a root portion of the blowing pipe and an inlet port of the air inlet pipe are in close fit, a gap is reserved between the portion outside the root portion of the blowing pipe and the inner wall of the air inlet pipe, an exhaust pipe which is arranged in an inclined mode is arranged inside the blowing head body, one end of the exhaust pipe is communicated with the middle portion of the air inlet pipe, and the other end of the exhaust pipe is led to the outside of the blowing head body. According to the blowing head, the blowing pipe is added inside the air inlet pipe, the exhaust pipe is arranged in an inclined mode at an angle of 45 degrees, air suction performed by a device is replaced with natural exhaustion, practices show that defects of body expansion, bottleneck expansion, molding deficiency and the like of produced glass bottles are eliminated, the computer programming time is reduced, the device maintenance is reduced and the efficiency is improved.

Description

The blow head of bottle-making machine

Technical field

The utility model relates to a kind of bottle-making machine, particularly a kind of be used for bottle-making machine be beneficial to air inlet, exhaust equilibrated blow head.

Background technology

In determinant system bottle system; Original blow head such as Fig. 1, shown in Figure 2 comprise blow head body 1, vertically have intake ducting 2 in blow head body 1 center; Intake ducting 2 is communicated with the aspirating air pipe 3 that is obliquely installed; The air intake-exhaust air-flow moves towards as shown in Figure 2, and the air intake-exhaust system of this blow head is controlled by computer, has following shortcoming:

1, since high to equipment requirements, equipment failure often appears, suction system gas leakage causes the deficiency of blowing, and product is bad.2, computer programming is complicated, and the technologist is required height.3, stable gas pressure requires high, and the air pressure shakiness causes exhaust bad, and product is bad.4, air inlet and exhaust can not be carried out simultaneously, and the processing procedure time is long, and cause air-flow chaotic easily; 5, inlet period is long, and bad phenomenon such as mouth expands can appear in vial.

Summary of the invention

The utility model has overcome the deficiency that exists in the above-mentioned prior art, and a kind of air intake-exhaust balance is provided, and not high to equipment requirements, maintenance cost is low, reduces the blow head that technological operation requires.

The technical scheme of the utility model is achieved in that

A kind of blow head of bottle-making machine comprises the blow head body, vertically has intake ducting in blow head body center; In intake ducting, be provided with gas blow pipe; The root of gas blow pipe and the ingress of intake ducting closely cooperate, and leave the gap between part beyond the gas blow pipe root and intake ducting inwall, in the blow head body, are provided with the gas exhaust duct that is obliquely installed; One end of gas exhaust duct is communicated with the middle part of intake ducting, and the other end of gas exhaust duct leads to blow head, and this is external.

Blow to the operator for fear of exhaust, as preferably, described gas exhaust duct is inclined relative to horizontal 45 degree.

As preferably, the head of gas blow pipe is tapered.Prevent that gas blow pipe from running into the vial oral area.

Adopted the beneficial effect of the utility model of technique scheme to be:

The utility model is to increase gas blow pipe in that intake ducting is inner, and is miter angle and has been obliquely installed gas exhaust duct, changes the nature exhaust into by equipment is air-breathing.Through practice, the vial of being produced has been eliminated trunk and has been expanded, and mouth expands, defectives such as body moulding deficiency, and the computer programming time decreased, maintenance of the equipment reduces, and efficient improves.

Fig. 3 is the structural representation of the utility model blow head;

Fig. 4 is the A-A sectional view of Fig. 3.

Embodiment

The embodiment of the utility model is following:

Embodiment: the blow head of a kind of bottle-making machine of the utility model; Like Fig. 3, shown in 4, comprise blow head body 1, vertically have intake ducting 2 in blow head body 1 center; In intake ducting 2, be inserted with gas blow pipe 4; The ingress of the root of gas blow pipe 4 and intake ducting 2 closely cooperates, and leaves gap 5 between part beyond gas blow pipe 4 roots and intake ducting 2 inwalls, and the head of gas blow pipe 4 is tapered.

In blow head body 1, be provided with the gas exhaust duct 6 that is obliquely installed, described gas exhaust duct 6 is inclined relative to horizontal 45 degree, and an end of gas exhaust duct 6 is communicated with the middle part of intake ducting 2, and the other end of gas exhaust duct 2 leads to outside the blow head body 1.

Claims
