Mechanical arm of bottle blowing machine

Abstract

The invention relates to a mechanical arm of a bottle blowing machine. The mechanical arm comprises a base and a first drive motor. A rotating assembly and a second drive motor capable of driving a rotating shaft of the rotating assembly to rotate are arranged on the base. The lower end of the rotating shaft stretches out of the base downwards to be connected with a connecting rod used for mounting of a clamping part. The rotating shaft can be driven by the second drive motor to drive the connecting rod to swing. A controller used for controlling the first drive motor and the second drive motor to be started is further included. The controller comprises a sensing detection unit and a simulation unit. The sensing detection unit is used for detecting the state of the first drive motor or the second drive motor. The simulation unit is used for controlling the rotating speed of the first drive motor or the second drive motor. The mechanical arm has the beneficial effects that assembling is easy, the high requirement for matching precision of a cam and a guide wheel in the prior art is not needed, and the phenomena that taking and conveying of bottles or bottle blanks fail, and bottle mouths are damaged are not likely to happen; and noise can be effectively lowered.

Description

technical field [0001] The invention relates to a bottle blowing machine manipulator. Background technique [0002] The support turntable of the rotary blow molding machine is equipped with a plurality of manipulators that rotate with the support turntable. The manipulator is composed of a clamping part for clamping bottles or preforms and a positioning mechanism installed on the support turntable. The positioning mechanism When the support turntable rotates, it can drive the clamping part installed on it to move radially and rotate on the support turntable, so as to complete the operation of picking up and delivering preforms or bottles at the predetermined station. It can be seen that the positioning mechanism on the manipulator can Whether the clamping part can be driven smoothly and accurately to move and rotate is an important factor for whether the bottle blowing machine can complete the bottle blowing work. The prior art has following deficiencies: as: 1, when the fi...

AI Technical Summary

Problems solved by technology

The prior art has following deficiencies: as: 1, when the first guide wheel and the second guide wheel roll on the outer track of cam and the groove on it, can produce bigger noise because of impact

2. It is necessary to use a large-volume cam, which is difficult to process, has a long production cycle, and is difficult to assemble

3. The matching accuracy of the first guide wheel and the second guide wheel with the outer track and groove of the cam is relatively high. If the matching accuracy does not meet the requirements, it is easy to fail to take and deliver the bottle or preform and damage the bottle mouth
