The two ends of the driving shaft 4 and the two ends of the driven shaft 6 are both connected with a bearing 3 with a seat, the bearing 3 with a seat is connected with the driving shaft 4 and is fixed on the hot pressing plate 1 through a fixed bearing seat 2, and the bearing 3 with a seat is connected with the driven shaft 6 and is fixed on the hot pressing plate 1 through an adjustable bearing seat 8. The speed reducer mounting base 12 is fixedly arranged on the hot pressing plate 1, the speed reducer 11 is arranged on the speed reducer mounting base 12, and the motor 10 is connected with the speed reducer 11. The chain 9 is sleeved on the driving chain wheel 5 and the driven chain wheel 7. The motor 10 drives the driving sprocket 5 and the driven sprocket 7 to rotate through the speed reducer 11, and further drives the chain 9 to rotate.

The hot pressboard 1 with fixed bearing frame 2 adjustable bearing frame 8 is provided with the heat insulating mattress between, is separated with heat insulating mattress 13 between fixed bearing frame 2 and the hot pressboard 1, between adjustable bearing frame 8 and the hot pressboard 1 to prevent that the heat on the hot pressboard 1 from going to in the chain 9 transmission.

The press for producing the plates with different specifications comprises a plurality of layers of hot pressing plates 1 which are arranged in parallel, for the hot pressing plate 1 at the top layer, as the plate unloading problem does not exist, a material belt 15 can be directly fixed on the thickened hot pressing plate 1 through a mounting rod 14, and the tightness of the material belt 15 can be adjusted through the mounting rod 14; for other hot pressing plates, the speed reducers 11 on the adjacent upper hot pressing plate and the lower hot pressing plate are symmetrically arranged to prevent interference.

The drive mechanism comprises a material strip 15, a mounting bar 14 and a chain 9. The material web 15 covers the hot press plate 1 and moves on the hot press plate 1. The chains 9 are arranged in parallel at both sides of the hot press plate 1. The chain 9 is provided with accessories, and two ends of the mounting rod 14 are connected with the accessories of the chain 9. In this embodiment, 4 parallel mounting bars 14 are respectively mounted on the attachments of the chains 9. The end of the material tape 15 is fixed to the mounting bar 14 on one side thereof by screws and then wound around the mounting bar 14, the material tape 15 is tensioned by adjusting the length of the winding, and the other end is fixed to the mounting bar 14 on the other side thereof, and one material tape 15 is fixed to each of 2 mounting bars 14, so that one material tape 15 can be provided on each of the upper and lower surfaces of the hot press board 1 in use.

The material web 15 may be a release material web. The anti-sticking material belt is made of Teflon. When the board is produced by adopting the aldehyde-free adhesive, two problems are mainly caused: one is that the initial viscosity of the plate blank is not enough, the strength of the plate blank is low, and the plate blank can be damaged due to falling of height difference in the conveying process; another is that the hot pressed particle or density board can stick to the hot press platen of the press, thereby seriously affecting product quality and possibly damaging the hot press platen. Thus, when the material web 15 is an anti-adhesive material web that covers the upper and lower surfaces of the hot press platen 1, the 2 sections of the anti-adhesive material web separate the blank from the hot press platen when the press is closed, preventing the sheet from sticking to the hot press platen 1. The press for producing the plates with different specifications is also suitable for producing the plates with aldehyde with different specifications.

The driving mechanism 17 is a hydraulic cylinder. In existing presses, 4 hydraulic cylinders are typically used to produce a 4 x 8 foot slab press. In this embodiment, the number of hydraulic cylinders is 6, so as to produce 4 × 9 feet and 4 × 10 feet of panels. The number and arrangement of the driving mechanisms 17 are determined according to the size of the plain plate to be processed, so that the stress of the plain plate to be processed is uniform, and the stress conditions of the hot-press plate during production of the plate with the maximum length and the plate with the minimum length are optimized as far as possible.

Hot pressboard 1 sets up for the thickening, hot pressboard 1's thickness is 140 ~ 160mm to increase hot pressboard 1 and resist the ability of warping, simultaneously driving shaft 4 with the diameter of driven shaft 6 also increases correspondingly, the diameter of driving shaft 4 is 140 ~ 160mm, the diameter of driven shaft 6 is 140 ~ 160mm, hot pressboard 1's thickness the driving shaft 4 the diameter with the diameter of driven shaft 6 equals.

The hot press plate 1 is provided with a thickness gauge 16. Due to the arrangement of the thickness gauge 16, the vacant positions of the plain plate to be processed on the hot pressing plate 1 can be filled, so that when a small-size plate is produced, the end part of the hot pressing plate 1 cannot be greatly deformed due to local lack of support. When the press pressure is large, the hot press board 1 comes into contact with the thickness gauge 16, so that the thickness gauge 16 functions to support the hot press board 1.

And the press for producing the plates with different specifications is provided with an induction head and a proximity switch. Through the induction of the induction head and the control of a proximity switch corresponding to the induction head, the material belt 15 can accurately convey the plain plate blanks with different lengths to the center of the press through controlling the plate feeding condition, so that the hot pressing effect is good.

A press for producing different sized plates comprises the following working steps:

and sawing the continuous plate blanks produced by the prepress at different lengths to obtain the plain plate blanks with different lengths. When the plate loading machine conveys a to-be-pressed plain plate blank, the speed reducer is started and drives the driving chain wheel 5 and the driving shaft 4 to rotate, the chain wheel and the chain drive the mounting rod and the material belt to rotate, and the material belt and the multi-layer plate loading machine synchronously run to carry out loading; when the mounting rods move to the two ends of the hot pressing plate, the speed reducer pauses, and the material belt 15 on the hot pressing plate 1 brings the plate blank to the central hot pressing position of the hot pressing plate; the driving mechanism drives the hot pressing plate to move upwards and close and presses the plate blank; after pressing is completed, the driving mechanism drives the hot pressing plate to move downwards and open, the speed reducer is started, the chain and a conveying device (generally a roller or a belt) on the plate unloading machine synchronously move, and workpieces are conveyed to the plate unloading machine. So that there is no relative movement between the workpiece and the material strip, avoiding wear of the material strip. According to the design, the upper plate and the unloading plate do not need the action of pushing the plate, so that the plates of different specifications can be prevented from being pushed, and the production requirements of the plates of different specifications can be met.

The invention has the beneficial effects that:

the press for producing the plates with different specifications is provided with a driving mechanism, a hot pressing plate and thickness gauges, so that the hot pressing plate is stressed uniformly when the press is used for producing the plates with different specifications, and the deformation is controlled within an allowable range;

and secondly, the press for producing the plates with different specifications can realize the plate loading and unloading actions of the plain plates with different specifications by enabling the plain plates to move at the same speed as the material belt, so that the plain plates with different sizes can be produced more conveniently, and customers can better adapt to the market requirements.
