Opening and closing manipulator for bottle blowing machine

Abstract

An opening and closing manipulator for a bottle blowing machine comprises a supporting plate and a cam plate which are rotated around corresponding axes, wherein a telescoping cam and an opening-closing cam are arranged on the cam plate; a slide block which is provided with a movable slide rail is mounted on the supporting plate; the slide rail extends to a bottle preform under the effects of a telescoping guide wheel and the telescoping cam; an opening-closing arm on a connecting plate at the tail end of the slide rail is used for driving a first clamping claw to open under the effects of an opening-closing guide rail and the opening-closing cam; the first clamping claw and a second clamping claw are mutually driven to synchronously open through a gear plate. According to the opening and closing manipulator for the bottle blowing machine, the clamping claws can be actively opened, so that the damage of the clamping claws to the bottle preform in a traditional driven opening manner and the requirement on the accuracy of the clamping claws can be avoided, and as a result, the bottle preform can be effectively protected, the product quality and the qualification rate can be improved, and meanwhile, the processing requirement of the clamping claws can be reduced.

Description

technical field [0001] The invention relates to bottle blowing equipment, in particular to an opening and closing manipulator for grabbing preforms or bottle bodies in a bottle blowing machine. Background technique [0002] Blow molding machine is equipment in the field of processing and manufacturing plastic bottles such as beverage bottles, oil bottles, and medicine bottles. It includes multiple components such as clamping and transporting preforms, and blowing preforms into bottle bodies. Such as figure 1 , 2 As shown, the slider 101 is driven by the driving part to the position facing the preform, and then the slide rail 102 is pushed and stretched towards the preform until the two grippers 103 press against the preform and are expanded by the preform, and then the slide rail no longer Pushed, the two grippers will clamp the preform under the action of the clamping tension spring 104 on the one hand, and retract under the action of the return tension spring 105 on the ...

AI Technical Summary

Problems solved by technology

In order to ensure the gripping accuracy, this structure requires high processing requirements for the gripper and is difficult to manufacture. At the same time, during the process of pressing the preform into the gripper, it is easy to be scratched by the gripper, which will not only generate debris, but also affect the The processing accuracy of the preform may even cause the deformation of the preform and produce waste products
