Hot press automatic in and out of the trigger machine

Abstract

The invention belongs to the technical field of plywood hot press molding, and discloses an automatic plate entering and exiting machine of a hot press. The automatic plate entering and exiting machine comprises a rack fixedly arranged at the feeding end of the hot press, a support plate frame corresponding to hot press working intervals of the hot press layer upon layer and a driving device which is arranged between the rack and the support plate frame and controls the support plate frame to do reciprocating motion; the end, close to the feeding end of the hot press, of the rack is provided with a linkage gate plate corresponding to the support plate frame layer upon layer, and power devices which control the linkage gate plate to do vertical reciprocating motion are arranged between the linkage gate plate and the rack. According to the automatic plate entering and exiting machine of the hot press, the structure is simple, operation is convenient, the working efficiency is high, multiple sheets of plywood simultaneously enter and exit the hot press, the heated and pressed time is same, and the machine is suitable for a hot pressing procedure of various plywood and especially suitable for the hot pressing procedure of zero-formaldehyde soybean substrate adhesive plywood; meanwhile, due to the fact that an operator is far away from the hot press for operation, the scalding and pressing accidents are avoided, and safety protection is better achieved.

Description

technical field [0001] The invention belongs to the technical field of plywood hot press forming, and in particular relates to a hot press machine for automatically entering and exiting a board. Background technique [0002] The existing plywood hot-pressing process generally uses 10-15 layers of hot-pressing machines, with a working temperature of 105-150°C and a working pressure of 500-800 tons. Boards are manually loaded and unloaded layer by layer, and the working environment is poor, and burns and crush injuries occur from time to time. At the same time, it takes a certain amount of time to enter and exit the board layer by layer. The plywood that enters the hot press successively has different heating times, resulting in differences in the bonding strength of the plywood. Especially for plywood with zero formaldehyde addition - soy based adhesive, this problem is more prominent. Contents of the invention [0003] The object of the present invention is to solve the...
