Electric tightening machine

Abstract

An electric tightening machine comprises a working platform, a lifting electric push rod arranged in the vertical direction is installed in the middle of the working platform, the lifting electric push rod is provided with a vertical ejector rod vertically extending upwards, and a lifting flat plate is installed at the upper end of the vertical ejector rod; horizontal electric push rods are arranged on the working platform and located on the periphery of the lifting electric push rod, the horizontal electric push rods are provided with transverse ejector rods extending towards the four sides of the lifting flat plate, the transverse ejector rods are provided with horizontal movable frames, and the horizontal movable frames are provided with a plurality of clamps. And the clamps are uniformly distributed along a straight line parallel to the corresponding side edge of the lifting flat plate. The tightening machine can be suitable for manufacturing more screens of different sizes and models, and the occupied space of a component system is small.

Description

technical field [0001] The invention belongs to the technical field of screen grid manufacturing equipment, and in particular relates to an electric stretching machine. Background technique [0002] The stretcher is an auxiliary equipment for the manufacture of screen grids. It applies the screen surface tension to the screen and the bonding force between the screen surface and the screen core. [0003] At present, the structure of the stretching machine includes a frame for supporting and placing the screen core, and a pulling mechanism is provided around the frame for holding the screen mesh and applying a transverse horizontal pulling force to the screen mesh to make the screen mesh have plane tension. The pulling mechanism is close to the edge of the screen core, and the height of the edge of the screen that is pulled is lower than the height of the upper edge of the screen core. When the screen is pulled, due to the existence of the screen pulling angle at the edge of ...

AI Technical Summary

Problems solved by technology

The frame of the traditional stretching machine is a fixed structure, which has restrictions on the size of the sieve core to be placed. If the size of the sieve core is too small, the pulling angle becomes smaller, and it is difficult to guarantee the gold sticking force. Therefore, the traditional stretching machine is only suitable for one size and type of sieve. grid manufacturing

In addition, the pulling mechanism in the traditional stretch-mounting machine includes manual drive and pneumatic drive. The manual drive is not only inefficient, but also labor-intensive. The structure of the pneumatic system is complex and the equipment takes up a lot of space.
