A hot bed airbag pressing plate

Abstract

The invention discloses a hot bed airbag pressure plate, which relates to the technical field of cardboard production. The key points of the technical solution are: a frame and a fixed plate fixed on the frame, the fixed plate is arranged horizontally and parallel to the heated bed, the fixed plate The side close to the conveyor belt is fixedly connected with a connecting plate perpendicular to the fixed plate, and the side of the connecting plate far away from the fixed plate is fixedly connected with a fixed box. , a pressing plate is arranged above the heating bed, the airbag is located on the side of the pressing plate away from the heating bed, the side of the airbag away from the pressing plate is relatively fixed to the heating bed, and an air inlet nozzle is arranged on the airbag. The invention solves the technical problem of non-uniform pressure produced by the existing hot bed pressure rollers in long-term use, and has the advantage of uniform pressure.

Description

technical field [0001] The invention relates to the technical field of cardboard production, in particular to a pressure plate for a hot bed air bag. Background technique [0002] During the cardboard processing process, the cardboard needs to be heated. In the prior art, the cardboard is transported through the conveyor belt. The heating bed is located in the cavity of the conveyor belt. The upper surface of the heating plate is in contact with the conveyor belt. In order to make the contact between the cardboard and the conveyor belt closer, A pressure roller with a certain weight is set on the conveyor belt to provide pressure. The cardboard passes between the pressure roller and the conveyor belt, and is squeezed by the pressure roller and the hot plate to make the cardboard contact with the hot plate more closely, so that the heating efficiency of the cardboard is higher, and Heating is more even. [0003] There is an existing cardboard wire heating bed pressure roller...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages in the prior art are: when the cardboard passes through the press roller, the press roller will rotate around the rotating shaft. During long-term use, the pressing roller will move continuously, and the friction between the rotating shaft and the supporting member will cause wear

The connecting hole on the support for the shaft to pass through will be deformed due to wear on one side, and the shaft will also be deformed due to wear.

[0005] Because the pressure of the cardboard needs to be moderate, if it is too large, the flute of the corrugated paper will be easily crushed; if it is too small, the contact between the cardboard and the hot bed will not be close enough.

[0006] The deformed shaft and the deformed connection hole are not easy to rotate relative to each other, which makes it difficult to control the pressure between the pressure roller and the cardboard
