Problems solved by technology
The present invention mainly introduces the fixing structure of the lower hot-pressing plate. When the hot-pressing plate stretches longitudinally, the fixing device will be subject to a larger pulling force (or pressure) and shearing force along the working direction. In the fixing structure, the long screw is directly connected and fixed with the connecting pin passing through the frame plate and the lower hot-pressed plate, which is a rigid connection. When the hot-pressed plate stretches longitudinally, the long screw is fully subjected to tension (or pressure) and shear force, long screws are slender rods, and after long-term use, the screws are easy to bend, deform or even break in the screw holes of the lower heat press plate, it is difficult to disassemble and replace the screws during maintenance, and the lower heat press plate The screw hole is damaged, and the broken screw cannot be removed, causing the lower heating plate to be damaged, which directly affects the normal production operation

Embodiment Construction
[0012] Attached below figure 1 , figure 2 The present invention is further described with embodiment:
[0013] One embodiment of the present invention is to produce a fixed structure (such as figure 1 , figure 2 Shown), the lower hot pressing plate and the third frame have four fixed structures in the direction of the cross section of the hot pressing plate. The fixed structure is mainly composed of connecting plate 101, a washer 102, short screw 103, long screw 104, connecting seat 105, b washer 106, guide rod 107, disc spring 108, c washer 109, d washer 110, bolt 111 and nut 112 Composition, the material of connecting plate 101 is Q235, quantity 8, with 8 washers 102 that material is Q235, 8 specifications are M36 * 105, the short screw 103 that material grade is 10.9 grades is connected on the lower surface of lower hot pressing plate. The third frame is composed of three single-piece frame plates with a thickness of 85mm. Four inner holes with a distance of 620mm and...

The present invention relates to method and device for fixing the lower hot pressing board onto continuous flat press. The technological is that the indirect connecting device with dispersed stress, and excellent buffering and damping consists of connecting board, washers, screws, connecting seat, guide rod, disc spring, and nuts. The present invention has the positive effects of dispersed stress, less deformation, great bearing capacity, convenient maintenance, high stability, etc.
Description
technical field [0001] The invention relates to a structure of a wood-based panel continuous press, in particular to a fixing structure of a hot-pressing plate of a flat-press continuous press. technical background [0002] The invention is mainly applied in the flat-press continuous press designed and developed for the first time in my country. The hot pressing plate is the working plane for pressure transmission, heat transfer and operation as steel belt and chain blanket of the flat continuous press. There are several heating circuits inside the hot pressing plate, and the heat transfer oil directly enters the hot pressing plate through the heating circuit. , The heat is directly transferred to the slab through chain blankets and steel belts. Since there is a temperature difference of more than 200°C in the heat transfer oil in the heat transfer plate between the working and non-working states of the continuous press, the heat transfer plate will inevitably experience gr...
