Abstract
The utility model relates to a bottle blowing machine field, concretely relates to a servo motor tension mechanism for rotary bottle blowing machine, it is including tensile pole, tensile pole passes through lead screw silk braid drive mechanism by servo motor to drive, servo motor's output and screw connection, tensile pole is fixed in on the silk braid, compared with the prior art, the utility model in stretching cyli driving method have a simple structure, tensile fast, tensile speed is even, the power supply stroke is short, production efficiency is high, product quality advantage such as good.
Description
Technical field
The utility model relates to bottle blowing machine field, is specifically related to a kind of servomotor drawing mechanism for rotary bottle blow-moulding machine.
Background technology
The manufacturing process of beverage bottle first manufactures bottle base by injection moulding, then heats or preheating bottle base, to be fixed by bottle embryo afterwards and carry out stretching and bottle blowing operation, finally unloaded from bottle blowing machine by shaping bottle by mould bases.
Stretched operation of the prior art is realized by draft cylinder, and it connects a stretching cylinder on the stretching bar of each station, promotes stretching masthead and stretch the bottle base heated, bottle base is extended by draft cylinder.
The mode that draft cylinder drives has many defects: first, by the restriction of the structure of cylinder own and operating characteristic, cylinder movement velocity is operationally uneven, or even the promotion stretching bar of vibration, this causes the product surface produced to have chatter mark, and bottle wall thickness is uneven; Secondly, the length dimension of cylinder need meet the requirement for height of beverage bottle, and it needs the cylinder being equipped with large-size usually, then with stopping means limited length, which increases structure complexity, makes equipment volume larger; Moreover its shortcoming also having stretching time long, this not only affects the quality of product, also affects production efficiency.
Summary of the invention
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of servomotor drawing mechanism for rotary bottle blow-moulding machine, and it is simple that this drawing mechanism has structure, and draw speed is fast, and draw speed is even, the drawing mechanism that power source stroke is short.
Concrete scheme of the present utility model is as follows:
For a servomotor drawing mechanism for rotary bottle blow-moulding machine, include stretching bar, described stretching bar is driven by leading screw silk braid transmission mechanism by servomotor, and the output of described servomotor is connected with leading screw, and described stretching bar is fixed on silk braid.
More preferably, be provided with stand, described stand is installed on the rotating disc of rotary bottle blow-moulding machine, the upper end of described stand is fixed with servomotor, described servomotor output is connected with leading screw, the two ends of described leading screw are fixed in stand by bearing, and described leading screw is provided with the silk braid be mated, and described silk braid is fixedly connected with stretching bar.
It is simple that the utility model has structure relative to draft cylinder type of drive of the prior art, and draw speed is fast, and draw speed is even, and power source stroke is short, the advantages such as production efficiency is high, good product quality.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
In figure, 1 rotating disc, 2 stands, 3 servomotors, 4 leading screws, 5 silk braids, 6 stretching bars.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing 1 is a kind of specific embodiment of the present utility model, it includes the stretching bar 6 stretched to bottle embryo, described stretching bar is driven by leading screw silk braid transmission mechanism by servomotor 3, and the output of described servomotor is connected with leading screw 4, and described stretching bar is fixed on silk braid 5; The rotary motion of servomotor is converted to the rectilinear motion of silk braid by leading screw silk braid transmission mechanism, silk braid drives stretching bar to move up and down, and achieves the stretched operation to bottle embryo.
Specifically on the rotating disc 1 of rotary bottle blow-moulding machine, stand is installed, the upper end of described stand is fixed with servomotor, described servomotor output is connected with leading screw, the two ends of described leading screw are fixed in stand by bearing, described leading screw is provided with the silk braid be mated, and described silk braid is fixedly connected with stretching bar.
