Pneumatic pawl manipulator

Abstract

The invention discloses a pneumatic pawl manipulator and belongs to the field of plastic processing machinery technology. The manipulator comprises a cylinder body, a piston, a cylinder rod and a pair of clamp arms connected to the cylinder rod and capable of gathering together and opening relatively. The manipulator is characterized in that one end of the cylinder rod connected to the clamp arms is provided with a U-shape rack; a transverse arm of the U-shape rack is connected to the cylinder rod; end portions of two vertical arms of the U-shape rack are respectively provided with a bearing; the pair of clamp arms are respectively slidably connected to the two vertical arms of the U-shape rack through a support with a bearing groove; the bearing runs in the bearing groove; and the support is connected to the cylinder body through a support pin. The invention has the advantages of simple structure, compactness, small volume and low energy consumption, etc.

Description

technical field [0001] The invention relates to a manipulator, in particular to an air claw manipulator, which is used for clamping and conveying plastic pipe blanks, and belongs to the technical field of plastic processing machinery. Background technique [0002] All kinds of plastic bottles such as mineral water bottles, cosmetic bottles, medicine bottles, etc. are widely used in daily life, medicine, chemical industry and other fields. Plastic bottle blowing machine is the most common machine for producing plastic bottles in the market, mainly including frame, heating device, spacing device, conveying device, bottle blowing device and other components. After the steps, enter the mold for blow molding. In the conveying process of each link, it is often necessary to clamp and convey the preform by the preform clamping manipulator. During the working process, the clamping manipulator needs to perform a series of opening and closing actions. In the existing manipulator, it...

AI Technical Summary

Problems solved by technology

In the existing manipulator, its two clamping arms are respectively installed on the driving device. During the action, the two clamping arms rotate around their respective rotation axes respectively. When the clamping arms are opened, the distance in the horizontal direction is relatively large. The distance between the manipulators is required to be large, and the number of manipulators that can be installed in a limited space is small, which increases the volume and floor space of the machine itself to a certain extent; in addition, the movement process of the manipulators needs to be as smooth as possible , small friction to reduce energy loss and improve efficiency
