Locking clamping device

Abstract

The invention discloses a locking clamping device which comprises an upper clamping device, a lower clamping device, a first driving device and a second driving device, wherein the first driving device and the second driving device control the upper clamping device and the lower clamping device to move up and down respectively. Semicircle grooves matched with the front end of a down feather filling pipe are formed in the upper surface of the upper clamping device and the upper surface of the lower clamping device. The upper clamping device comprises a first fixing block, a first clamping block, a second clamping block, a third driving device and a fourth driving device. The lower clamping device comprises a second fixing block, a third clamping block, a fourth clamping block and an elastic part. According to the locking clamping device, after a cutting piece to be filled with down feather is clamped, the cutting piece to be filled with the down feather can be pulled to be flat, at the moment, when a cutting piece after filling is completed is sealed, an opening to be sealed of the cutting piece is not prone to wrinkling, the sealing quality is improved, and therefore the locking clamping device can meet the use requirements of a down feather filling machine with the sealing function after down feather filling is completed.

Description

technical field [0001] The invention relates to a locking clip device, in particular to a locking clip device of a down filling machine with a sealing function after the down filling is completed, and belongs to the technical field of down filling device components. Background technique [0002] my country is a big down producing country. At present, there are two main methods of filling down in down products: for a large amount of filling at one time, first insert the down pipe into the gall cavity to be filled, and grasp the mouth of the down by hand, then To prevent the down from overflowing during down filling, the blower is used to generate an inhaled airflow to fill the down into the cavity through the high-speed rotating impeller; for down products with small cavity, the filling amount at one time is very small, and the operator will weigh it in advance. The down is stuffed into the gall cavity by hand. Filling with a blower has high efficiency, but the high-speed rota...
