Description

Technical Field

[0001] The invention belongs to the technical field of multilayer board preparation, and in particular relates to a multilayer board preparation device and a preparation method thereof. Background Art

[0002] As a common building material, multilayer boards are widely used in many fields such as construction and furniture manufacturing. However, ordinary multilayer boards are prone to bending and breaking when subjected to large loads, making it difficult to meet the needs of high-strength application scenarios. In addition, ordinary boards do not have good fire resistance and may accelerate the spread of fire in the event of a fire. At the same time, traditional equipment has a single function and it is difficult to complete multiple processes at the same time, resulting in a long production cycle and high costs. In addition, due to the lack of an effective bubble removal mechanism, the air bubbles generated during the lamination process will affect the quality of the finished product and cause a decrease in bonding strength.

[0003] The Chinese patent application number 202311112997.5 discloses a fireproof multilayer board processing device for building fireproof materials, including a board and a base, a lifting cylinder is fixedly connected to the surface of the base, a lifting seat is fixedly connected to the end of the lifting cylinder, the lifting seat is slidably connected to the surface of the base, two pressing rollers are arranged in the lifting seat, and vibration rods are arranged on opposite sides of the two pressing rollers, a threaded rod is rotatably connected to the inner wall of the lifting seat, a limiting rod is fixedly connected to the inner wall of the lifting seat, and the rod arm of the threaded rod has two threads in opposite directions, and also includes two groups of rolling parts, both of which are arranged in the lifting seat, and the two pressing rollers are relatively displaced by the arrangement of the two groups of rolling parts, and also includes two groups of knocking parts, which are respectively transmission-connected to the two groups of rolling parts. The present invention has the effect of improving the pressing uniformity of the fireproof multilayer board and improving the pressing quality through the mutual cooperation between the above structures.

[0004] The production method and product of recycled multi-layer board raw material in the Chinese patent with application number 201811223912.X are carried out according to the following steps: (a) Purchase abandoned construction multi-layer boards, remove nails and surface impurities; (b) Use a construction waste multi-layer board thickness sorting machine to accurately sort and stack the multi-layer boards according to thickness; Then use a waste multi-layer board cutting machine to cut the heads of the same type of multi-layer boards after thickness sorting, and then cut them into equal width strips of different specifications, at this time, obtain multi-layer board strips of different specifications, equal width and thickness; (c) Use an automatic glue coating machine to apply glue, splice them in the template to form a mold plate, and layer them together with the template into a multi-layer four-sided side pressing hot press to simultaneously press them into a mold plate. The four-sided side pressing hot press simultaneously presses and presses the side, and its side pressure is 4-5.5MPa, the positive pressure is 4-5.5MPa, the temperature is 185-250℃, and the time is 3-9 minutes; (d) After cooling, use a recycled wood board sander to sand and remove surface impurities to obtain this product.

[0005] However, there are still the following problems in practical applications, specifically:

[0006] 1. Limited improvement in mechanical properties: Although both patents attempt to improve certain properties of the board (such as fire resistance or environmental value), they provide little description on how to fundamentally improve the overall rigidity and bending resistance of the board, especially through physical structural improvements (such as the use of wire mesh). This means that when encountering large external forces in actual applications, the board may still be deformed or damaged.

[0007] 2. Lack of comprehensive performance optimization: Neither of them describes in detail how to comprehensively improve the performance of the board through technological innovation, including but not limited to mechanical strength, fire resistance, production efficiency and finished product quality. For example, there is no mention of elements such as wire mesh that can effectively limit the expansion of tiny cracks and play a role in blocking the spread of flames.

[0008] 3. Low level of automation: The production equipment in the two patents has a relatively low degree of automation and still requires a lot of manual intervention, which not only increases labor costs but also reduces production efficiency.

[0009] Therefore, how to overcome the above-mentioned technical problems and defects becomes a key issue that needs to be solved. Summary of the invention

At the same time, the presence of wire mesh can help evenly disperse the pressure applied by the outside, prevent the board from breaking due to excessive local force, and effectively limit the expansion of small cracks.

[0041] 3.

[0058] The multilayer board preparation device and preparation method of the present invention will be described in more detail below with reference to the accompanying drawings and through specific implementations.

[0059] refer to Figure 1-Figure 8 The present invention uses wire mesh as a structural support, which greatly enhances the overall rigidity and bending resistance of the multilayer board. It can also help to evenly disperse the externally applied pressure, prevent the board 1 from being broken due to excessive local force, effectively limit the expansion of small cracks, and block the spread of flames. The equipment integrates an integrated operation process with a high degree of automation, reduces manual intervention, improves production efficiency, and can improve the bonding strength of the finished product, so that each layer of single board can be well fitted before pressing, reduces bubble formation, and effectively eliminates air bubbles generated during the pressing process. It includes a board 1 with a multi-layer structure design, a processing frame 2, a display frame 3 and a pressing frame 4, and the display frame 3 is arranged in the middle position between the processing frame 2 and the pressing frame 4. The board 1 is provided with at least three layers, and the length and width dimensions of each layer of the board 1 are the same. The board 1 of the middle layer is fixedly provided with at least one layer of wire mesh. First, place the bottom board 1 on the display frame 3.

[0060] By using the wire mesh as a structural support, the overall rigidity and bending resistance of the multilayer board are greatly enhanced, and it is particularly suitable for application scenarios that need to carry heavy objects or withstand large external forces. At the same time, the presence of the wire mesh can help evenly disperse the pressure applied by the outside, prevent the board 1 from breaking due to excessive local force, and effectively limit the expansion of small cracks. Moreover, as a non-combustible material, the wire mesh can block the spread of flames when a fire occurs, extend the fire resistance time of the board 1, and buy more time for the evacuation of personnel. The wire mesh forms a physical barrier to prevent insects and other small pests from entering the interior of the wood, while reducing moisture penetration and reducing the risk of mold growth.

[0061] In order to automatically apply adhesive to the bottom of the middle layer of the board 1, Figure 3It is shown that a processing module 5 for applying adhesive to the plate 1 is arranged at the top of the processing frame 2. The processing module 5 includes a paint box 51 fixedly arranged horizontally at the top of the processing frame 2. The paint box 51 is a rectangular structure with an open top, and a heating plate 52 is fixedly arranged inside the paint box 51. The heating plate 52 is a mature prior art and will not be described in detail here. When in use, the adhesive is poured into the paint box 51, and the heating plate 52 is controlled to work so that the adhesive is always in a liquid state, which is convenient for subsequent application. Racks 53 are fixedly arranged on both sides of the paint box 51, and a roller 54 is arranged on the paint box 51. Paint cotton 55 is sleeved on the roller 54, and gears 56 meshing with the corresponding racks 53 are fixedly arranged at both ends of the roller 54. A guide groove 57 is horizontally provided on the side of the paint box 51, and a guide rail 58 is slidably provided on the guide groove 57, and a bracket 59 is fixedly provided on the guide rail 58, and a first bidirectional motor 60 for driving the corresponding gear 56 to rotate is fixedly provided on the bracket 59. The first bidirectional motor 60 is controlled to work and drive the corresponding gear 56 to rotate. The two gears 56 rotate on the rack 53 to drive the roller 54 to move parallel to the paint box 51. At this time, the paint cotton 55 rolls in the paint box 51, so as to apply the adhesive to the bottom of the plate 1. In this process, the first bidirectional motor 60 moves parallel to the paint box 51 through the sliding of the guide rail 58 in the guide groove 57. When it moves to the end, the first bidirectional motor 60 is controlled to reverse to return each part.

[0062] In order to realize the movement of the plate 1, Figure 3-Figure 5 It is shown that a feeding rack 6 for moving the plate 1 is arranged on the processing rack 2. Slide rails 10 are fixedly arranged on both sides of the processing rack 2, and the feeding rack 6 is slidably arranged on the slide rails 10. A roller 11 is rotatably arranged at the bottom end of the feeding rack 6, and the roller 11 abuts against the top of the slide rail 10. A top plate 12 is horizontally fixedly arranged at the top of the feeding rack 6, and at least one first hydraulic rod 13 is vertically fixedly arranged on the top plate 12, and the telescopic ends of the first hydraulic rod 13 are fixedly arranged with a magnetic seat 14 that can abut against the top of the plate 1. The magnetic seat 14 is a mature prior art and will not be described in detail here. After evenly applying adhesive to the bottom of the plate 1, the first hydraulic rod 13 and the magnetic seat 14 are controlled to work, and the magnetic seat 14 is fitted with the top of the plate 1, so that the plate 1 is adsorbed by the cooperation of the magnetic seat 14 and the wire mesh. Then, the feeding rack 6 is pushed to move on the slide rail 10 via the rollers 11 , thereby placing the plate 1 above the bottom plate 1 placed on the display rack 3 .

[0063] A hydraulic frame 15 is fixedly arranged horizontally in the middle of the feeding frame 6, and an oil circuit 16 is provided inside the hydraulic frame 15. A hydraulic cylinder 17 connected to the oil circuit 16 is fixedly arranged vertically at the top of the top plate 12. Second hydraulic rods 18 are fixedly arranged horizontally at both ends of the hydraulic frames 15 on both sides of the processing frame 2, and the second hydraulic cylinder 17 is connected to the oil circuit 16. T-shaped frames 19 that can support the plate 1 are arranged on both sides of the processing frame 2. The middle cross bars of the T-shaped frames 19 are arranged relatively, and the opposite sides of the T-shaped frames 19 are fixedly arranged with the corresponding telescopic ends of the second hydraulic rods 18. When processing the plate 1 in the middle, the hydraulic cylinder 17 is controlled to work, and the oil is transported to the second hydraulic cylinder 17 through the oil circuit 16, so that the T-shaped frame 19 is relatively moved. At this time, the plate 1 is supported by the T-shaped frame 19, which is convenient for the subsequent application of the adhesive. When the sheet 1 moves to the appropriate position above the display rack 3, the hydraulic cylinder 17 is controlled to work, and the T-shaped frame 19 is moved in reverse, thereby releasing the support for the sheet 1. At this time, the first hydraulic rod 13 is controlled to work, pushing the sheet 1 to move downward to fit with the sheet 1 on the bottom layer, and then the magnetic seat 14 and the second hydraulic rod 18 are controlled to stop working, and the position limit of the sheet 1 on the middle layer is released. Then the various parts are returned to their positions, and the adhesive on the top of the sheet 1 on the middle layer can be applied at this time. After that, the top sheet 1 is placed on the sheet 1 on the middle layer to achieve the bonding of the multi-layer board.

[0064] The top of the placing rack 3 is horizontally rotatably provided with a plurality of rollers 20, and the placing rack 3 is arranged in the middle of the slide rail 10 at one end of the feeding rack 6. When the sheet 1 is completely fitted, the sheet 1 is pushed, so that the sheet 1 is moved to the inside of the pressing rack 4 through the rollers 20.

[0065] In order to achieve the lamination of multilayer boards, Figure 6-Figure 8 It is shown that both the upper and lower parts of the pressing frame 4 are provided with a lifting pressing plate 7.

A lifting pressing plate 24 is provided at the bottom end of the bracket 21, and the pressing plate 24 can pass through the bracket 21 and abut against the bottom end of the lower pressing plate 7.

[0066] Support frames 25 are fixedly arranged on both sides of the bottom of the middle position of the pressing frame 4, and a plurality of limit rods 26 are horizontally arranged at the lower part of the pressing frame 4, and the end of each limit rod 26 is fixedly arranged with the corresponding support frame 25. A plurality of third hydraulic rods 27 fixed with the corresponding limit rods 26 are vertically arranged at the opposite ends of the support frame 25, and the telescopic ends of the third hydraulic rods 27 are fixedly arranged with the bottom end of the extrusion plate 24. A limit groove 28 is provided at the top of the lower pressing plate 7, and the top of the limit groove 28 is lower than the top of the display rack 3.

[0067] Guide rods 29 are vertically fixed on both sides of one end of the upper part of the pressing frame 4. Each guide rod 29 vertically penetrates the end of the corresponding lower pressing plate 7. A sliding sleeve 30 that slides with the guide rod 29 is fixed on the pressing plate 7. When the pressing plate 7 rises, it moves on the guide rod 29 through the sliding sleeve 30 to reduce friction. A plurality of fourth hydraulic rods 31 are vertically fixed on the top of the pressing frame 4. The telescopic end of the fourth hydraulic rod 31 is fixed to the top of the upper pressing plate 7. During pressing, the fourth hydraulic rod 31 is controlled to work to drive the upper pressing plate 7 to move downward, thereby cooperating with the lower pressing plate 7 to achieve pressing of the sheet 1. After pressing, each component is controlled to return to its original position.

[0068] In order to achieve a good fit before lamination, Figure 7It is shown that a horizontally movable heating unit 8 is provided in the middle of the pressing frame 4. The heating unit 8 includes a heating coil 81 which is provided at the end of the pressing frame 4 and can slide between a first fixed plate 22 and a second fixed plate 23.

After the sheet 1 is placed on the limiting groove 28, the second bidirectional motor 84 is controlled to work and drive the lead screw 83 to rotate, so that the heating coil 81 is moved horizontally in the pressing frame 4. During this process, the heating coil completely wraps the bracket 21. At the same time, the electromagnetic coil 82 is controlled to work to heat the wire mesh, so that the adhesive is active and fills the gaps between the layers of single boards, so that the sheet 1 can be well fitted before pressing. After heating, the second bidirectional motor 84 is controlled to reverse and the heating coil is returned to its position. During this process, the guide rod 85 is used for guiding.

[0070] Instructions for use of the multilayer board preparation device of the present invention: First, place the bottom board 1 on the display rack 3. Pour the adhesive into the coating box 51, and control the heating plate 52 to work so that the adhesive is always in a liquid state, which is convenient for subsequent coating. Control the hydraulic cylinder 17 to work, and transport the oil to the second hydraulic cylinder 17 through the oil circuit 16, so as to move the T-shaped frame 19 relatively. At this time, place the middle board on the T-shaped frame 19, and support the board 1 through the T-shaped frame 19, which is convenient for subsequent coating of the adhesive.

[0071] The first bidirectional motor 60 is controlled to work and drive the corresponding gear 56 to rotate. The two gears 56 rotate on the rack 53 to drive the roller 54 to move parallel to the coating box 51. At this time, the coating cotton 55 rolls in the coating box 51, so that the adhesive is applied to the bottom of the plate 1. In this process, the first bidirectional motor 60 moves parallel to the coating box 51 through the sliding of the guide rail 58 in the guide groove 57. When it moves to the end, the first bidirectional motor 60 is controlled to reverse and return all parts. After the adhesive is evenly applied to the bottom of the plate 1, the first hydraulic rod 13 and the magnetic seat 14 are controlled to work, and the magnetic seat 14 is fitted with the top of the plate 1, so that the plate 1 is adsorbed by the cooperation of the magnetic seat 14 and the wire mesh. Then the feeding rack 6 is pushed to move on the slide rail 10 through the roller 11, so that the plate 1 is placed above the bottom plate 1 placed on the display rack 3.
