Problems solved by technology

[0003] In the production process of plywood, a hot-pressing device is required. The existing hot-pressing device for plywood production can generally only heat-press plywood of a certain size, and cannot fix plywood of different sizes, resulting in a smaller size. When the plywood is hot-pressed, the position of the plywood may shift, resulting in poor effect after hot-pressing the plywood and affecting the quality of the plywood

Embodiment 1

[0031] see Figure 1-6 , in the embodiment of the present invention, a kind of hot-pressing device for plywood production comprises hot-press box 1, heating plate 11 and base 13, and one side outside hot-press box 1 is fixedly connected with motor box 17, and motor box 17 is provided with Motor 18, the inner lower end of autoclave 1 is fixedly connected with support column 12, and the upper end of support column 12 is fixedly connected with base 13, conveniently plywood is placed on the base 13, and one side of base 13 is provided with limit bar 14, and limit The position bar 14 is fixedly connected to one side of the autoclave 1, and the limit bar 14 is provided with a chute 15 inside, and the chute 15 is provided with a positive and negative threaded screw rod 16, and the transmission between the positive and negative threaded screw rod 16 and the motor 18 connection, the end of the limit rod 14 away from the motor 18 is fixedly connected with a fixed block 19, the inside of...

Embodiment 2

[0040] During the implementation of the present invention, the applicant found that in the process of hot-pressing plywood, rotating the positive and negative threaded screw 16 drives the two stoppers 23 to move relative to each other through the slider 22, which can realize the limitation and fixation of plywood of different sizes. But in order to ensure that the plywood is formed by one-time hot pressing, the area of ​​the heating plate 11 must not be less than the area of ​​the plywood between the two movable stoppers 23, so the two stoppers 13 are generally located under the heating plate 11, and are produced during production. During the process, as the plywood is heated and pressurized, the plywood is gradually compressed, and the thickness gradually decreases. The buffer spring 10 pushes the heating plate 11 to move downward through the connecting rod, and continues to heat the plywood. The stopper 23 located under the heating plate 11 If the height is too large, the dow...

Embodiment 3

[0043] After the applicant further improved the device and implemented it, it was found that when the device was heat-bonding thick plywood, the thickness of some plywood could reach more than 10 cm, and the scheme in Example 2 was used to heat-bond this type of particularly thick plywood At this time, it is necessary for the hot pressing plate 11 to compress the compression spring 29 largely through the pressing block 28, and at the same time, the reaction force of the compressed spring 29 that is greatly compressed to the hot pressing plate 11 through the pressing block 28 is relatively large, and the larger reaction force will It affects the heat-sealing effect of the heat-pressing plate 11 on the heat-sealing plate below, resulting in insufficient heat-sealing pressure of the plywood, which affects product quality. Therefore, the present application makes a further improvement when aiming at the hot pressing of this type of thicker plywood.

Abstract

The invention discloses a hot-pressing device for plywood production based on 5G technology, which includes a hot-press box, a heating plate and a base. A limit rod is provided on one side of the base, and the limit rod is fixedly connected to one side inside the autoclave. A chute is provided inside the limit rod, and a positive Reverse thread screw rod, the end of the limit rod away from the motor is fixedly connected with a stopper, the inside of the stopper is provided with a limit slot, the inside of the limit slot is provided with a limit block, and the positive and negative thread screw rod The surface is threadedly connected with a slider, and one side of the slider is fixedly connected with a stopper, and the stopper includes a slot, a pressure block compression spring, and a pressure sensor. Limiting the plywood can make the quality of the plywood processed by the hot pressing device better.

Description

technical field [0001] The invention relates to the technical field of plywood hot pressing, in particular to a hot pressing device for plywood production. Background technique [0002] Plywood is a three-layer or multi-layer board-like material made of wood sections that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Plywood is one of the commonly used materials for furniture and can be used for aircraft, ships, Used as timber for trains, automobiles, buildings and packing boxes. my country is a big exporter of plywood. With the development of the economy, the production of plywood is facing huge challenges and threats from outside. It is necessary to adjust and upgrade the structure of the plywood industry, improve production technology, and control the production process to effectively and continuously produce high-quality plywood products. , To enhance the core competitiveness, in order to have a stable market. [0003] In the product...
