Description

Technical Field

[0001] This utility model relates to the field of plywood shaping technology, specifically to an environmentally friendly multi-layer plywood bonding and shaping device. Background Technology

[0002] Multi-layer plywood is widely used in building formwork, furniture manufacturing, packaging materials and other fields due to its high strength, good stability and high material utilization.

[0003] In the heating stage, traditional devices often use a single heating source on one side or at the bottom. The single heat source structure causes heat to accumulate in a local area. In addition, the support platform is mostly a solid structure, which hinders heat diffusion and ultimately leads to uneven heating of the plate. In the pressing stage, existing equipment often uses an integral flat plate pressing. The integral pressing causes the pressure to concentrate in the middle part, which can easily cause the plate to deform under stress.

[0004] Therefore, an environmentally friendly multi-layer plywood bonding and shaping device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an environmentally friendly multi-layer plywood bonding and shaping device that can solve the problems of uneven heating and uneven pressure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a shaping chamber, the main body of which is a rectangular cube, one side of which protrudes outward to form a convex part, the convex part of which has several square openings, at least three hydraulic columns are fixedly installed on the inner wall of the top of the shaping chamber, a support platform is fixedly installed inside the shaping chamber, and several heating chambers are opened inside the shaping chamber, with heating components fixedly installed inside the heating chambers.

[0007] Preferably, the square openings are linearly distributed on the protruding part of the shaping chamber, the square openings penetrate into the interior of the shaping chamber, and the square openings connect the inner and outer spaces of the shaping chamber.

[0008] Preferably, the hydraulic columns are linearly distributed on the top of the shaping chamber, and a pressing block is fixedly provided at the lower end of the hydraulic columns. The pressing block is configured as an X-shaped structure and is located inside the main structure of the shaping chamber.

[0009] Preferably, a connecting rod is fixedly provided on the outside of one of the hydraulic columns sandwiched in the middle position. The connecting rod extends into the interior of the protruding part of the shaping chamber. A movable window is fixedly provided at the extended end of the connecting rod, and an activated carbon filter is fixedly connected inside the movable window.

[0010] Preferably, the movable window is slidably disposed inside the protruding part of the shaping chamber, and the lower horizontal height of the movable window is lower than the lower horizontal height of the pressing block.

[0011] Preferably, the support platform is configured as a honeycomb three-dimensional structure, and a certain gap is left between the bottom of the support platform and the inner wall of the bottom of the shaping chamber.

[0012] Preferably, the heating chamber is located on the three non-protruding inner walls inside the shaping chamber body, and the heating chambers located on the same side are linearly distributed on the inner wall surface of the shaping chamber.

[0013] Compared with the prior art, this utility model provides an environmentally friendly multi-layer plywood bonding and shaping device, which has the following beneficial effects: 1. This utility model achieves the goal of reducing the weight of the support platform and ensuring its load-bearing strength by setting the support platform as a honeycomb three-dimensional structure and leaving a gap between the bottom and the inner wall of the shaping chamber, while facilitating the upward diffusion of heat and making the bottom of the plywood evenly heated.

[0014] 2. This utility model achieves the effect of radiating heat from different directions by setting linearly distributed heating chambers on the three non-protruding inner walls of the shaping chamber, and fixing heating components inside the heating chambers, thereby making the temperature field inside the chamber more uniform and improving the consistency of bonding and shaping.

[0015] 3. This utility model achieves the effect of uniformly applying pressure to different areas of the plywood by setting at least three linearly distributed hydraulic columns on the inner wall of the top of the shaping chamber, and fixing X-shaped pressing blocks at the lower end of the hydraulic columns, thereby avoiding excessive local pressure that could cause the board to deform.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example:

[0019] Please see Figure 1 - Figure 4 An environmentally friendly multi-layer plywood bonding and shaping device in this embodiment includes a shaping chamber 1. The main body of the shaping chamber 1 is a rectangular cube. One side of the main body of the shaping chamber 1 protrudes outward to form a protrusion. Several square openings 2 are provided through the protrusion of the shaping chamber 1. At least three hydraulic columns 3 are fixedly installed on the inner wall of the top of the shaping chamber 1. A support platform 8 is fixedly installed inside the shaping chamber 1. Several heating chambers 9 are opened inside the shaping chamber 1. Heating components 10 are fixedly installed inside the heating chambers 9. When bonding and shaping multi-layer plywood, the multi-layer plywood coated with environmentally friendly adhesive is placed on the support platform 8. The hydraulic column 3 is activated to drive the pressing structure to press down. At the same time, the heating component 10 is energized and heats up, causing the temperature inside the shaping chamber 1 to rise and accelerate the curing of the adhesive. The square opening 2 of the raised part balances the air pressure inside the chamber and provides ventilation, thus achieving environmentally friendly bonding and shaping of the plywood. The heating component 10 is powered by electricity to enable the heating wire inside the heating component 10 to perform the heating function. The implementation of this heating function is existing technology, and its specific structural composition and working principle will not be described in detail in this embodiment.

[0020] Square openings 2 are linearly distributed on the protruding part of the shaping chamber 1. Square openings 2 penetrate into the interior of the shaping chamber 1 and connect the inner and outer spaces of the shaping chamber 1. When the interior of the shaping chamber 1 is heated, air convection can be formed with the outside through the square opening 2 to promptly expel the small amount of gas volatilized by the adhesive, while avoiding excessive air pressure inside the chamber from affecting the shaping accuracy of the plywood. The linear distribution ensures uniform ventilation.

[0021] Hydraulic columns 3 are linearly distributed on the top of the shaping chamber 1. A pressing block 4 is fixedly installed at the lower end of the hydraulic columns 3. The pressing block 4 is set in an X-shaped structure and is located inside the main structure of the shaping chamber 1. When the hydraulic structure is activated, the hydraulic columns 3 are linearly distributed to apply pressure to different areas of the plywood. The X-shaped pressing blocks 4 reduce their own weight while ensuring the pressure area, and the cross structure can disperse the pressure to the surface of the plywood, avoiding excessive local pressure that could cause the board to deform and improving the flatness of the bonding and shaping.

[0022] A connecting rod 5 is fixedly installed on the outside of a hydraulic column 3 sandwiched in the middle. The connecting rod 5 extends into the inside of the protruding part of the shaping chamber 1. A movable window 6 is fixedly installed at the extended end of the connecting rod 5. An activated carbon filter 7 is fixedly connected inside the movable window 6. The movable window 6 is slidably installed inside the protruding part of the shaping chamber 1. The lower horizontal height of the movable window 6 is lower than the lower horizontal height of the pressing block 4. When the hydraulic column 3 drives the pressing block 4 to rise and fall, the connecting rod 5 simultaneously drives the movable window 6 to move. The activated carbon filter 7 adsorbs and purifies the gas that is about to pass through the square opening 2, removing harmful components volatilized from the adhesive and achieving environmentally friendly shaping. Its lower end is lower than the pressing block 4, so that when the pressing block 4 contacts the plywood, the movable window 6 can contact the surface of the support platform 8, preventing the gas from escaping without passing through the activated carbon filter 7. The lower end of the movable window 6 is made of heat-resistant elastic material, such as silicone rubber, to ensure that the movable window 6 can still move when the plywood is being squeezed and shaped.

[0023] The support platform 8 is designed as a honeycomb three-dimensional structure, and a certain gap is left between the bottom of the support platform 8 and the bottom inner wall of the shaping chamber 1. The honeycomb structure reduces the weight of the support platform 8 while ensuring sufficient load-bearing strength. The bottom gap facilitates the upward diffusion of heat, making the bottom of the plywood heated evenly and avoiding poor bonding caused by local temperature differences.

[0024] The heating chamber 9 is located on the three non-protruding inner walls inside the main body of the shaping chamber 1, and the heating chambers 9 located on the same side are linearly distributed on the inner wall surface of the shaping chamber 1. The heating chambers 9 distributed on three sides can radiate heat into the shaping chamber 1 from different directions. Combined with the linear distribution, the temperature field inside the chamber is more uniform, avoiding the difference in curing speed of different parts of the plywood caused by traditional single-sided heating, and improving the consistency of bonding and shaping.

[0025] The working principle of the above embodiment is as follows: The multi-layer plywood coated with environmentally friendly adhesive is placed on the honeycomb support platform 8 inside the shaping chamber 1. The hydraulic column 3 linearly distributed at the top of the shaping chamber 1 is activated, which drives the lower X-shaped pressing block 4 to press down on the plywood. At the same time, the heating component 10 in the heating chamber 9 linearly distributed on the inner wall of the non-protruding three sides of the shaping chamber 1 is energized and heats up, so that the temperature inside the chamber rises evenly to accelerate the curing of the adhesive. When the hydraulic column 3 rises and falls, the connecting rod 5 on the outer side of the middle hydraulic column 3 synchronously drives the sliding window 6 in the protruding part of the shaping chamber 1 to slide. The lower end of the sliding window 6 is lower than the pressing block 4 and moves with the hydraulic column 3, ensuring that the gas convecting through the square opening 2 linearly distributed in the protruding part is purified by the activated carbon filter 7. The gap between the bottom of the support platform 8 and the bottom of the shaping chamber 1 is conducive to heat diffusion, and finally the environmentally friendly and uniform bonding and shaping of the multi-layer plywood is achieved.

[0026] The use of hydraulic structures and heating components 10 are common existing technologies. The installation, connection or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. They are common knowledge in the field. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
