Locking device used in sheet feeding beam of feeding machine

Abstract

The invention discloses a locking device used in a sheet feeding beam of a feeding machine. The locking device comprises a sliding block, the sheet feeding beam, an internal upper clamp, an external upper clamp, an internal lower clamp, an external lower clamp and a line rail, wherein when sheets are sent to the clamp port, a vertical movement air cylinder pushes the sliding block to drive the internal lower clamp to upwards move and clamp the sheets with the internal upper clamp; then a horizontal movement servo motor drives a whole internal clamp mechanism to forwards move to arrive to a fixed position; the external lower clamp is driven by the air cylinder to upwards move and clamp the sheets with the external upper clamp; the internal lower clamp and the internal upper clamp are separated and return to an initial position; the sheet feeding process is realized by such reciprocating motion; the device is movably fixed by the lower clamp, convenient to use, and difficult to damage; the sheets are fixed after being positioned; the processing precision is improved; a clamping plate does not need to be replaced; and the device has excellent application prospect.

Description

technical field [0001] The invention relates to a locking device used in the sheet feeding girder of a feeder, and belongs to the field of mechanical technology. Background technique [0002] The sheets cut and formed by the blister machine need to be loaded by an automatic feeding machine. When feeding, the rack needs to be moved or rotated. After feeding, it is locked by a locking device. The locking device is set on the feeding In the machine feeding beam, it can prevent movement during production and processing, which will affect the processing accuracy. There are many disadvantages in the locking device currently used, or the structure is too complicated, or the driving device for driving the locking device to open and lock requires relatively large power, which is not conducive to saving production costs and reducing power consumption. [0003] In order to solve the above problems, the patent No. "201310212144.9" provides a locking device for the feeding mechanism. Th...
