Abstract
Description

[0002] In a hot press machine for rapid veneer processing of wood-based panels, the hot press platen liner is the component that comes into direct contact with the finished panel surface and is widely used to control the surface quality and pattern of the finished panel. The liner is secured closely to the working surfaces of the upper and lower hot press platens. The most common securing method involves using a fixed tensioning hook on one side to hold the liner in place and a pneumatic tensioning hook on the other side. The cylinder's thrust tightens the liner, securing it close to the working surface of the hot press platens.
[0003] The patent with publication number "CN101439526A" is named "Liner hot pressing plate for artificial board hot pressing plate". The public document hooks the left and right ears of the liner by setting two cylinders, and then uses the two cylinders at the same time to tension the liner. The disadvantage of this tensioning method is that: because the cylinder needs to be connected to an external inflation device, and the inflation device and the cylinder are connected by a pipeline, when the pipeline is damaged and leaks, the tensioning force of the cylinder is invalid, which in turn affects the tensioning effect of the liner. In addition, the use of the cylinder with the inflation device increases the cost of the entire device, that is, increases the production cost of the device in the public document. Based on this, the utility model designs an automatic tensioning mechanism for the liner of the artificial board hot pressing plate to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide an automatic tensioning mechanism for a lining plate of a hot pressing plate of an artificial board, so as to solve the problems raised by the above-mentioned background technology.

[0030] According to the operating steps in Example 1, when the slide column 401 drives the limiting rod 404 to move along the outer direction of the guide groove 2, the slide column 401 simultaneously drives the connecting plate 9 together with the limiting ring 14 to drive the worm 8 to move along the outer direction of the connecting sleeve 6, thereby ensuring that the worm 8 and the slide column 401 are in a state of synchronous displacement. When the lining plate is tensioned and connected to the hot pressing plate, the reverse function of the first motor 301 is first turned on to separate the slot 405 from the lifting ear of the lining plate, and then the second motor is turned on. 11 has the forward rotation function, the second motor 11 drives the driving gear 12 to drive the driven gear 13 together with the connecting sleeve 6, the sliding pin 7 and the worm 8 to rotate, and then the worm 8 drives the worm wheel 10 together with the rotating sleeve 403 to rotate, through the action of the threaded transmission between the rotating sleeve 403 and the limiting rod 404, the limiting rod 404 together with the connecting block 406 moves downward along the direction of the sliding column 401, and then the limiting rod 404 is separated from the lifting ear area of the lining plate, and the staff can remove the lining plate from the sliding column 401.
