Description

Technical Field

[0001] The invention relates to the technical field of plywood manufacturing for wooden buildings, and in particular to a full-automatic hot-pressing and laminating production line for plywood and a hot-pressing and laminating method thereof. Background Art

[0002] In the plywood (wooden building formwork) production equipment, the hot press device is one of the most important equipment. At present, there are three types of loading methods for hot press devices: the first is full manual loading and unloading of boards; the second is manual loading of boards to the loading machine, manually pushing the processed boards in the hot press to the receiving rack, and then feeding from the loading machine into the hot press, and manually stacking the boards at the receiving rack (drying rack); the third is manual loading of boards to the loading machine, automatically sending the processed boards in the hot press to the receiving rack (drying rack) and leaving the embryo boards on the loading machine in the hot press, and then stacking them. The first and second types of employees have high labor intensity and low efficiency, and employees have to operate close to the hot press, the temperature is high, and there are safety hazards. There are currently many types of loading machines for the third type of loading, but they are complex to manufacture and operate, and due to design defects, they are limited to the loading and unloading of embryo boards with a thickness of more than 7mm, and are not applicable to embryo boards with a thickness of less than 7mm.

[0003] The patent with publication number CN103331788A discloses a plate loading machine for a hot pressing device, characterized in that it includes a main frame; a plate rack, which is arranged in the main frame and can reciprocate from the inside of the main frame to the rear of the main frame, the plate rack includes a plurality of plates arranged at intervals up and down, each plate includes a middle part and two end parts, and the middle part is higher than the two end parts; a handrail column, which is fixed to the left and right ends of the rear of the main frame; and a handrail, one end of the handrail is fixed to the handrail column, and the other end extends outward, and a handrail is arranged on the left and right of each plate, and the handrail can be horizontally rotated above the two end parts of the plate to the outside of the main frame with the handrail column as a rotating shaft. The present invention is suitable for loading and unloading plywood or wooden building formwork blanks of 3mm and above, and it is easy to manufacture, simple to operate, and accurate and convenient to load plates.

[0004] The patent with the publication number CN107599372A discloses an automatic film coating production line for building templates, which includes a hot pressing device, a blanking device for assembling substrates and film coating paper, a loading and unloading device arranged beside the blanking device and having the same number of layers as the hot press, and a cooling plate device and a plate unloading device. The baffle device arranged on the hot pressing device includes a rotating shaft, and a plurality of levers and forks that are mutually leading and parallel to each other are installed on the rotating shaft. The movable frame of the loading and unloading device includes multiple layers of stainless steel plates, and the number of stainless steel plates of these forks and the movable frame is the same as the number of layers of the hot pressing device. After adopting the above structure, the loading and unloading device simultaneously sends the blanks assembled by the blanking device to the hot pressing device, the rotating shaft of the baffle device rotates, the forks on the rotating shaft block the blanks, and the loading and unloading device returns to its position, so that the blanks will fall on the hot press, and at the same time, the stainless steel plates of the movable frame of the loading and unloading device will push the sheet out of the press, and the hot pressing device completes the hot pressing of both sides of the blanks and the unloading of the finished plate.

[0005] The prominent defect of the above device is that when the plywood with film paper on the top and bottom loaded by the plate loader enters the hot press and retreats, it is blocked by a blocking device (a crutch or a fork), so that the plywood with film paper on the top and bottom is loaded into the hot press and then hot pressed. The inventor found in practice that before hot pressing and laminating, the film paper under the plywood is not tightly combined with the plywood. This way of loading the plates can easily cause the film paper under the plywood to wrinkle, especially when the thickness of the plywood is relatively thick, such as more than 8mm, it is also easy to damage the film paper under the plywood, affecting the quality of hot pressing and laminating. In addition, when the plate loader is loading, the assembly substrate device can only stagnate, resulting in poor continuity of the device. Summary of the invention

[0006] The purpose of the present invention is to design a fully automatic hot-pressing laminating production line for plywood in view of the deficiencies in the prior art, so as to achieve lamination on the top and bottom of the plywood and reduce damage to the film paper under the plywood. The production line has a high degree of automation, greatly improves product quality, improves work efficiency, saves energy consumption, and ensures the safety of workers.

[0007] The technical solution adopted by the present invention is as follows.

[0008] The fully automatic hot-pressing film laminating production line for plywood is characterized by comprising a film laminating conveying device, a lifting conveyor, a board loading machine, a hot press machine, a cooling rack, a board receiving device, and an adsorption device capable of feeding materials to the film laminating conveying device, which are arranged in sequence;

[0009] The loading machine is vertically arranged with third plywood horizontal conveyor belt frames with the same number as the hot-pressing chambers of the hot press and whose positions correspond to the heights of the hot-pressing chambers of the hot press; the cooling rack is vertically arranged with fourth plywood horizontal conveying devices with the same number as the hot-pressing chambers of the hot press and whose top surface positions correspond to the heights of the hot-pressing chambers of the hot press; the third plywood horizontal conveyor belt frames are provided with a third conveyor belt; the ends of each third plywood horizontal conveyor belt frame away from the hot press are connected to a horizontal traveling mechanism, and under the drive of the horizontal traveling mechanism, each third plywood horizontal conveyor belt frame can enter / exit the hot-pressing chamber of the hot press corresponding to its height.

[0010] The film-laminating conveying device comprises a film-laminating conveying device frame and a first plywood horizontal conveying frame arranged thereon, wherein the first plywood horizontal conveying frame is provided with a first conveying belt with a horizontal top surface and a first conveying belt driving motor;

[0011] The lifting conveyor includes a lifting conveyor frame, a second plywood horizontal conveyor frame installed on the lifting conveyor frame, and a second plywood horizontal conveyor frame lifting device; the second plywood horizontal conveyor frame is provided with a second conveyor belt with a horizontal top surface and a second conveyor belt driving motor.

[0012] The beneficial effects of the present invention are as follows: a first conveyor belt is provided on the film conveying device, a second conveyor belt with a horizontal top surface is provided on the second plywood horizontal conveyor frame, and a third conveyor belt is provided on the third plywood horizontal conveyor belt frame of the plate loading machine. The arrangement of the first conveyor belt, the second conveyor belt, and the third conveyor belt can make the film paper under the plywood move slowly during the horizontal movement and lifting process, and is not easy to wrinkle. The third plywood horizontal conveyor belt frame of the plate loading machine can be inserted into the corresponding hot pressing cavity of the hot press, and the third plywood horizontal conveyor belt frame can be slowly pulled out. At the same time, the third conveyor belt on the third plywood horizontal conveyor belt frame rotates, and the surface movement direction of the third conveyor belt on the third plywood horizontal conveyor belt frame is opposite to the withdrawal direction of the third plywood horizontal conveyor belt frame, so that the hot-pressed plywood film paper combination on the conveyor belt remains unchanged relative to the horizontal position of the hot press and falls into the hot pressing cavity of the hot press below it. In this way, the plywood with film paper on both the top and the bottom can be smoothly put into the hot press. The rolling friction method of the first conveyor belt, the second conveyor belt, and the third conveyor belt is adopted. Compared with the sliding friction method of the prior art, the film paper under the plywood is not easy to wrinkle. When the board loading machine is loading, the film conveying device can still work and convey to the lifting conveyor, and the lifting conveyor can also be lifted to the height of the next loading. The device has good working continuity and high degree of automation, which greatly improves product quality, improves work efficiency, saves energy consumption, and ensures the safety of workers.
