Hot pressing plate structure of double-sided machine
Technical Field
The utility model relates to a two-sided quick-witted hot plate portion of cardboard production facility, especially a two-sided quick-witted hot plate structure.
Background
Present double-facer hot plate portion includes frame, hot plate and drive belt, and hot plate and drive belt setting are in the frame, and the drive belt is located the hot plate top, and it is between the interval to form the cardboard conveying between drive belt and the hot plate, and the cardboard conveying interval that gets into hot plate portion after the hole paper and the laminating of facial tissue of seeing after the starching (also can be the laminating of the hole paper of seeing more than two-layer and facial tissue), heats the cardboard through the hot plate to paste with higher speed and stick with paste futilely admittedly, the cardboard shaping. However, the heat of the heating mode is transferred from the bottom of the paper board to the top, the heating efficiency is low, and the paper board cannot be quickly conveyed in the hot plate part, so that the processing speed of the corrugated board production line is limited.
In addition, when 3 or more layers of paper boards are processed (e.g., 5 layers of paper boards, 7 layers of paper boards), the paste at the bonding part between the upper layer of paper board and the paper board is difficult to dry due to only bottom heating, which affects the quality of the paper board.
Therefore, it is desirable to design a device that can heat the upper portion of the paperboard.
Disclosure of Invention
An object of the utility model is to overcome the not enough of above-mentioned prior art existence, and provide a simple structure, reasonable, control is convenient, laborsaving energy-conserving, can be used for carrying out the double facer hot pressing plate structure that adds heat pressure to cardboard upper portion to overcome prior art's not enough.
The purpose of the utility model is realized like this:
the utility model provides a two-sided quick-witted hot pressing plate structure, includes hot plate and crossbeam, its characterized in that: the hot plate is connected with the pressure plate mechanism more than two sets, and the pressure plate mechanism includes rocking arm subassembly and flexible drive arrangement, and the rocking arm subassembly includes rocking arm, the articulated seat of first articulated seat and the articulated seat of second, and the rocking arm both ends are articulated with the articulated seat of first articulated seat and second respectively, and the first articulated seat is connected with the top surface of hot plate, and the articulated seat of second is connected with the crossbeam, and flexible drive arrangement sets up in the swing arm top, and flexible drive arrangement beam-ends is articulated with swing arm and connecting block respectively, and the connecting block is connected with the crossbeam.
The purpose of the utility model can also adopt the following technical measures to solve:
as a more specific scheme, the telescopic driving device is a cylinder, the cylinder is vertically arranged above the rocker arm, a tail seat is arranged at the tail of the cylinder body of the cylinder, the tail seat is hinged with the connecting block, a cylinder head is arranged at the outer end of a piston rod of the cylinder, and the cylinder head is hinged with the two ends of the rocker arm.
As a further scheme, one end of the connecting block is connected with the cross beam, and the other end of the connecting block is suspended outside the cross beam.
As a further scheme, the sets of pressing plate mechanisms are linearly arranged along the width direction of the hot plate, and the cross beam points along the width direction of the hot plate.
As a further scheme, the hot plate is a steam hot plate or an electromagnetic hot plate.
As a further scheme, a steam channel communicated with the steam heating plate is arranged in the steam heating plate, a steam inlet is formed in the top surface of the steam heating plate, and a steam outlet is formed in the side surface of the steam heating plate, so that connection of a steam pipeline is facilitated.
The utility model has the advantages as follows:
(1) the double-sided machine hot-pressing plate structure can control the hot plate to move up and down so as to press the hot plate above the paper board (such as on a transmission belt above the paper board), so that the upper part of the paper board is heated and pressurized, and the quality and the efficiency of paper board adhesion are improved;
(2) the double-sided machine hot-pressing plate structure is connected with the telescopic driving device through the rocker arm assembly, and one end of the rocker arm assembly is supported through the cross beam, so that the telescopic driving device can lift the hot plate more labor-saving and energy-saving;
(3) the hot plate of this kind of double facer hot pressing plate structure and the rocking arm other end between realize the swing cooperation through articulated, its angle can automatically regulated, avoids crushing the cardboard, has further ensured the quality of cardboard.
