Abstract

The utility model discloses a heating mechanism for a bottle blowing machine, comprising a heating aluminum seat (1), a shaft sleeve (2) inserted into the heating aluminum seat, a portion of the shaft sleeve inserted into the heating aluminum seat being movably connected to the heating aluminum seat via a deep groove ball bearing unit, and a head shaft (3) being installed in the shaft sleeve. The utility model has the beneficial effects of low friction and long service life.

Description

Blow molding machine heating mechanism

technical field

The utility model relates to the field, in particular to a heating mechanism of a bottle blowing machine.

Background technique

The components of the traditional heating mechanism are heavy, and the transmission mechanism generally uses self-lubricating bearings or cam bearings, which leads to large friction between structural components, greater damage to the machine itself, and reduces the service life of the machine. It is easy to cause uneven heating of preforms and high rate of defective blow molding products.

Utility model content

The purpose of this utility model is in order to solve the above-mentioned problem, has designed a kind of bottle blowing machine heating mechanism.

The technical solution of this utility model to achieve the above object is, a blow molding machine heating mechanism, including a heating aluminum seat 1, a shaft sleeve 2 is inserted on the heating aluminum seat, and the part of the shaft sleeve inserted into the heating aluminum seat The deep groove ball bearing unit forms an active connection with the heating aluminum seat, and the head shaft 3 is installed in the shaft sleeve.

The head shaft 3 is inserted into the shaft sleeve and forms a fixed connection structure with the shaft sleeve.

A sprocket 4 is sleeved on the shaft sleeve 2 .

The heating aluminum base 1 is provided with a cam bearing 7 .

The deep groove ball bearing unit includes a deep groove ball bearing 5 and a deep groove ball bearing 6 .

The head shaft is made of aluminum alloy.

The heating mechanism of the bottle blowing machine produced by the technical solution of the utility model, the head shaft is changed from the previous steel material to the aluminum alloy material, which has strong thermal conductivity and is easy to dissipate heat. At the same time, the self-weight is reduced. , Using deep groove ball bearings to replace the existing self-lubricating bearings or cam bearings to reduce friction, thereby reducing the wear of the entire device, increasing production efficiency and yield.

Description of drawings

Fig. 1 is the structural representation of the heating mechanism of the bottle blowing machine described in the utility model;

In the figure, 1, heating aluminum seat; 2, shaft sleeve; 3, head shaft; 4, sprocket wheel; 5, deep groove ball bearing one; 6, deep groove ball bearing two; 7, cam bearing.

Detailed ways

The utility model is described in detail below in conjunction with the accompanying drawings. Fig. 1 is a structural schematic diagram of the heating mechanism of the bottle blowing machine described in the utility model. As shown in the figure, a heating mechanism of the bottle blowing machine includes a heating aluminum seat 1, A shaft sleeve 2 is inserted into the heating aluminum base, and the part of the shaft sleeve inserted into the heating aluminum base forms a flexible connection with the heating aluminum base through a deep groove ball bearing unit, and a head shaft 3 is installed in the shaft sleeve. Wherein, the head shaft 3 is inserted into the shaft sleeve and forms a fixed connection structure with the shaft sleeve; the shaft sleeve 2 is sleeved with a sprocket 4; the heating aluminum seat 1 is provided with a cam bearing 7; the deep groove The ball bearing unit includes deep groove ball bearing one 5 and deep groove ball bearing two 6 parts.

The feature of this technical solution is to use deep groove ball bearings to replace the self-lubricating bearings or cam bearings in the traditional heating mechanism, thereby reducing friction, thereby reducing machine wear, avoiding uneven heating of preforms and low yield shortcoming.

In this technical solution, the preform is fixed on the head shaft, the shaft sleeve is sleeved on the lower end of the head shaft, and the deep groove ball bearing is located between the shaft sleeve and the heating aluminum seat, replacing the traditional self-lubricating bearing or cam bearing, and the cam bearing is fixed on the Outside the aluminum seat, it is used to support the whole device on the circular track and assist the whole device to slide; the sprocket is the kinetic energy driving part of the heating mechanism, which drives the whole device to slide through the chain.

The above-mentioned technical solutions only embody the preferred technical solutions of the technical solutions of the present utility model, and some changes that may be made by those skilled in the art to some parts thereof reflect the principles of the present utility model and belong to the protection scope of the present utility model within.
