A cutting device for sealing, separating and closing

Abstract

The invention discloses a cut piece seal splitting and integrating clamping device which comprises an upper pressing device, a lower pressing device, a first driving device and a second driving device. The first driving device and the second driving device respectively control the upper pressing device and the lower pressing device to move up and down. The lower surface of the upper pressing device is provided with a semicircular groove matching with the front end of a down filling pipe. The upper pressing device comprises a first compressing block, a second compressing block, a clamping block, a third driving device and a fourth driving device. The first compressing block and the second compressing block which are capable of moving leftward and rightward through the third driving device and the fourth driving device respectively are arranged under the first driving device. The clamping block is arranged between the first compressing block and the second compressing block and fixed on the first driving block. The lower pressing device and the upper pressing device are identical in structure and mutually symmetrical. By the application of the cut piece seal splitting and integrating clamping device, a seal of a cutting piece to be sealed which is smooth and high in quality wrinkles less easily, and operating requirements of a down filling machine with a sealing function after down filling is completed are met.

Description

technical field [0001] The invention relates to a flattening device, in particular to a piece sealing, separating, closing and clamping 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] At present, the existing method of filling down is to use a down filling machine for filling down. The down filling machine is equipped with a down filling tube and a lock clamp device. The lock clamp device is arranged at the front end of the down filling tube. Insert it into the cavity of the cutting piece, and then start the locking device, which will clamp the opening of the cutting piece, so as to avoid the overflow of down during the filling process, which not only improves the working environment, but also prevents the price Waste of expensive down. With the development of down filling machines, a down filling machine with a sealing function a...

But the clamping device only plays the role of simply clamping the opening of the cut piece. At this time, when the filled cut piece is sealed, the part to be sealed of the cut piece is easy to wrinkle, thus affecting the sealing quality. , unable to meet the use requirements of the down filling machine with sealing function after filling the down

[0003] The Chinese patent "A Locking Clamping Device" applied by our company, the application number is 201320524560.8, discloses a locking clamping device, including an upper clamping device, a lower clamping device and a control to move the upper clamping device and the lower clamping device up and down The first driving device and the second driving device; the lower surface of the upper clamping device and the upper surface of the lower clamping device are provided with a semicircular groove matching the front end of the down filling tube; the upper clamping device includes the first A fixed block, a first clamping block, a second clamping block, a third driving device and a fourth driving device; the lower clamping device includes a second fixing block, a third clamping block, a fourth clamping block and Elastic parts; wherein the first clamping block, the second pressing block, the third clamping block and the fourth clamping block play the role of flattening the sealing of the cut pieces to be filled, but when these clamping blocks When the left and right directions are moved relative to each other, there is no pressing force in the middle of the cut piece to be filled, so when sealing, the middle of the cut piece is prone to wrinkles, resulting in a decline in the quality of the seal, which cannot meet people's increasingly high demands.
