Full-automatic hot-pressing membrane laminating assembly line for plywood and hot-pressing membrane laminating method thereof

Abstract

The invention discloses a full-automatic hot-pressing membrane laminating assembly line for plywood and a hot-pressing membrane laminating method thereof. The full-automatic hot-pressing membrane laminating assembly line comprises a sticking membrane conveying device, a lifting conveyor, a plate loading machine, a hot pressing machine, a cooling stand and a plate receiving device which are arranged in sequence, and an adsorption device for feeding materials to the sticking membrane conveying device, wherein third plywood horizontal conveyor belt frames are vertically arranged on the plate loading machine, the number of the third plywood horizontal conveyor belt frames is the same as the number of hot pressing cavities of the hot pressing machine, and the positions of the third plywood horizontal conveyor belt frames correspond to the heights of the hot pressing cavities of the hot pressing machine; fourth plywood horizontal conveying devices are vertically arranged on the cooling stand, the number of the fourth plywood horizontal conveying devices is the same as the number of the hot pressing cavities of the hot pressing machine, and the positions of the top surfaces of the fourthplywood horizontal conveying devices correspond to the heights of the hot pressing cavities of the hot pressing machine; third conveyor belts are arranged on the third plywood horizontal conveyor beltframes; and the end, far away from the hot pressing machine, of each third plywood horizontal conveyor belt frame is connected to a horizontal travelling mechanism. The automatic hot-pressing membrane laminating assembly line for plywood has the advantages of good hot pressing membrane laminating effect and high automation degree.

Description

technical field [0001] The invention relates to the technical field of plywood manufacturing for wooden buildings, in particular to a fully automatic hot-pressing and film-coating assembly line for plywood and a hot-press and film-coating method thereof. Background technique [0002] In the plywood (wooden building formwork) production equipment, the hot pressing device is one of the most important equipment. At present, there are roughly three types of board loading methods for hot pressing devices: the first is full manual loading and unloading of boards; the second is manual loading to the loading machine, and manually pushes the processed boards in the hot press to the board rack , and then feed the material from the loading machine into the hot press, and manually stack the boards at the board rack (drying board rack); the third is to manually load the boards to the loading machine, and automatically process the processed materials in the hot press The boards are sent ...

AI Technical Summary

Problems solved by technology

The first type and the second type of employees have high labor intensity and low efficiency, and the employees have to operate close to the heat press, the temperature is high, and there are potential safety hazards

The third type of plate loading machine currently has various forms, but the manufacturing is complicated and the action is complicated, and due to design defects, it is limited to the loading and unloading of the embryonic plate with a thickness of more than 7mm, and cannot be used for the embryonic plate with a thickness of less than 7mm. Be applicable

[0005] The outstanding defect of the above device is that: when the plywood loaded by the loading machine is equipped with film paper on the upper and lower sides and enters the hot press machine and is retracted, it is blocked by a blocking device (hand or fork), so that the upper and lower sides are provided with film paper. The plywood of the paper is loaded into the heat press machine and then heat pressed

The inventor found in practice that before the hot-press lamination, the film paper under the plywood is not tightly combined with the plywood. This way of loading the board is easy to make the film paper under the plywood wrinkle, especially when the thickness of the plywood is relatively thick. When the thickness is above 8mm, for example, it is easy to damage the film paper under the plywood, which will affect the quality of the hot-pressed film

In addition, when the board loader is loaded, the assembled substrate device can only stagnate, resulting in poor continuity of the device
