Description

Technical Field

[0001] The invention belongs to the technical field of fireproof boards and relates to a method for manufacturing fireproof boards, in particular to a method for manufacturing a bamboo-wood multilayer flame-retardant fireproof board. Background Art

[0002] Fireproof board is a three-layer or multi-layer plywood made by peeling logs into wood chips or planing wood blocks into small wood blocks, treating the wood chips with flame retardant treatment and then gluing them with adhesive. Usually, odd-numbered wood chips are used, and the fiber directions of adjacent layers of wood chips are made perpendicular to each other. Fireproof board is a flame-retardant board produced with wood as the main raw material. Due to its reasonable structure and fine processing in the production process, it can generally overcome the defects of wood and greatly improve and enhance the physical and mechanical properties of wood. At the same time, flame-retardant plywood also overcomes the disadvantage of easy combustion of ordinary plywood, effectively improving the flame retardant properties of plywood. The production of flame-retardant board is an important method to fully and reasonably utilize wood and improve the properties of wood.

[0003] After searching, it is found that a method for producing flame-retardant boards is disclosed in Chinese patent literature [Application No.: 201810832002.5; Announcement No.: CN 108908535 B]. This method includes the following steps: (1) raw material selection; (2) rotary cutting; (3) preparation of flame-retardant solution; (4) high-temperature steaming; (5) natural air cooling; (6) core board classification, primary board coiling and standby; (7) secondary board and tertiary board repair treatment; (8) glue coating, applying glue to both sides of the secondary board, and bonding polymer flame-retardant fiber layers to the surfaces after glue coating; (9) one-time pressing: laying the secondary board and the tertiary board in layers, and then laying the primary board as the panel on the top and bottom layers, and then pressing them using a cold press; (10) spraying a layer of reinforced glass fiber layer on the surface of the pressed multi-layer flame-retardant board for surface coating; (11) laying a decorative layer on the front of the multi-layer flame-retardant board and hot pressing. The flame retardant board produced by the present invention has a flame retardant effect that is 3-5 times that of the existing flame retardant boards on the market, fully realizes the flame retardant characteristics of the wooden board, and the wooden board has high strength and a wide range of applications.

[0004] Although the flame retardant board production method disclosed in this patent improves the flame retardant effect to a certain extent, the processing steps of this process are relatively cumbersome, and the fireproof board can only be processed into a plate-like structure. When stacked and stored, it is not convenient to take and place a single board, and it also has certain disadvantages in the bonding strength of multi-layer boards, and the board layers are prone to falling off. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a method for manufacturing a bamboo-wood multi-layer flame-retardant fireproof board. The technical problem to be solved by the invention is: how to simplify the process steps, improve the quality of the flame-retardant board and facilitate its placement.

[0011] S3. Dry the removed bottom plate, bamboo-wood panel and base plate with hot air at a temperature of 40-60 degrees, and keep the moisture content of the bottom plate, bamboo-wood panel and base plate at 8%-10%;

[0012] S4, applying glue to the surface of the bottom plate, placing the substrate on the bottom plate for pasting, and then performing static pressure molding;

[0013] S5, applying glue to the surface of the substrate and the trapezoidal groove, inserting the trapezoidal block of the bamboo panel into the trapezoidal groove, and then performing static pressure molding;

[0014] S6. Drill holes on the formed fireproof board body, the drilling positions correspond to the mounting holes on the bottom plate, and the drilling positions include the second large-diameter hole and the second small-diameter hole;

[0015] S7, spraying a flame retardant layer on the surface of the bamboo panel, and then spraying a decorative layer on the surface of the flame retardant layer;

[0016] S8. The fireproof board body after spraying is placed on a storage rack, and adjacent fireproof boards are placed in a staggered manner.

[0017] In the step 2, when the bottom plate, bamboo-wood panel and base plate are soaked, gaps are left between adjacent plates, and the gap distance is 1-1.5 cm.

[0018] In the step S6, when drilling holes in the fireproof board body, the four corners of the fireproof board body are drilled at the same time, and the hole positions are composed of a first small-diameter hole and a first large-diameter hole.

[0019] The outer diameter of the mounting block is smaller than or equal to the inner diameter of the second large-diameter hole.

[0020] After the soaking in step S2 is completed, the mixture is heated and boiled to a temperature of 70-80 degrees. After boiling for 20-30 minutes, the mixture is taken out of the water.

[0021] The equipment used in steps S6-S8 is an integrated processing equipment, which includes a frame, a wheel frame is fixed at the upper end of the frame, a belt roller is rotatably connected to the wheel frame, a transmission belt for driving the belt roller is fixed on the wheel frame, a plurality of limit plates are fixed to the outer periphery of the transmission belt, a support seat is fixed to the wheel frame through a connecting rod, a pillar is fixed to the lower side of the support seat, the lower end of the pillar is fixedly connected to the frame, a plurality of brackets are fixed to the upper side of the support seat, a plurality of conveying rollers are rotatably connected to the brackets, the conveying rollers are in contact with the inner periphery of the conveying belt, and a drilling mechanism, a first spraying mechanism, a second spraying mechanism and a placement rack are provided on the frame.

[0022] With the above structure, during operation, the formed fireproof board body is placed on the conveyor belt, the fireproof board is limited and fixed by the limiting plate, and then the conveyor belt transports the fireproof board body to the bottom of the drilling mechanism, and then the drilling mechanism is used to drill holes on the formed fireproof board body, the drilling positions correspond to the mounting holes on the bottom plate, and the positions of the holes drilled include the second large-diameter hole and the second small-diameter hole. After the drilling is completed, the fireproof board body passes through the conveyor belt under the first spraying mechanism, the first spraying mechanism sprays the flame retardant layer on the surface of the bamboo and wood panel, the fireproof board body passes through the conveyor belt under the second spraying mechanism, and then the second spraying mechanism sprays the decorative layer on the surface of the flame retardant layer, and then the processed fireproof board body is placed on the placement rack.

[0023] The drilling mechanism includes a first mounting frame, which is fixed on a frame, a first hydraulic cylinder is fixed on the upper end of the first mounting frame, a lifting plate is fixed below the first hydraulic cylinder, a first motor is fixed at the four corners of the lower side of the lifting plate, a first drill bit is fixed at the output shaft end of the first motor, a second motor is fixed at the lower center of the lifting plate, a second drill bit is fixed at the output shaft end of the second motor, and both the first drill bit and the second drill bit include a large diameter portion and a small diameter portion, and the small diameter portion is fixed at the lower end of the large diameter portion.

[0024] By adopting the above structure, during operation, the first hydraulic cylinder can be used to drive the lifting plate to descend, so that the first drill bit and the second drill hole can be lowered to perform drilling operations on the fireproof board body. When drilling, the small diameter part first contacts the fireproof board body to perform small-diameter drilling, and then a large-diameter drilling is performed on the upper end of the small-diameter hole. This can be completed in one go, saving time and effort.

[0025] The first spraying structure and the second spraying mechanism have the same structure, the first spraying mechanism includes a second mounting frame, the second mounting frame is fixed on the frame, a paint box is fixed at the upper end of the second mounting frame, a second hydraulic cylinder is fixed on the second mounting frame, a sealing cover is fixed at the lower end of the second hydraulic cylinder, the lower end of the sealing cover is a wavy structure, a paint spray seat is fixed inside the sealing cover, a plurality of paint spray heads are fixed on the lower side of the paint spray seat, the paint spray seat is connected to the feeding pump in the paint box through a hose, a square cover is fixed at the upper end of the sealing cover, a jet chamber with an opening at the lower end is provided in the square cover, a plurality of air supply pipes are fixed at the upper end of the jet chamber, and the air supply pipes are connected to the high-pressure air source through pipelines.

[0026] With the above structure, when spraying the flame retardant layer and the decorative layer, the sealing cover is driven down by the second cylinder so that the lower end of the sealing cover contacts the conveyor belt, the high-pressure gas source and the feeding pump are turned on, and while spraying, the high-pressure gas source and the jet chamber can be used to form a wind curtain around the fireproof board body through the gas, so that the paint will not escape and will not contact the sealing cover, thereby ensuring the quality of spraying and will not cause pollution to the sealing cover. It is convenient for long-term use and has good practicality.

[0027] The placement rack includes two vertical plates, which are fixed on the frame. A placement slot located between the two vertical plates is opened on the upper side of the frame. An electric telescopic rod is fixed inside the placement slot. A rising plate is inherently provided at the upper end of the electric telescopic rod. An avoidance slot is opened on the vertical plate, and a support plate is rotatably connected in the avoidance slot.

[0028] The vertical surface of the avoidance groove is inclined, and an inclined plate is fixed on the vertical plate. The left inclined plate is located in front of the left vertical plate, and the right inclined plate is located in the rear of the right vertical plate.

[0029] When the fireproof board is placed on the lifting plate, the electric telescopic rod drives the lifting plate to rise. When the fireproof board contacts the supporting plate, the supporting plate is driven to rotate, so that the fireproof board continues to rise. After the fireproof board is separated from the supporting plate, the supporting plate returns to its original position under the action of gravity, and the electric telescopic rod is retracted, so that the fireproof board can be placed on the supporting plate. When the next fireproof board rises, the same operation is adopted. After the fireproof board rises and contacts the inclined plate, the inclined plate contacts the corner of the fireproof board, and the fireproof board rotates under the action of the inclined plate. Each time a fireproof board is raised, it rotates once, so that adjacent fireproof boards are staggered, which is convenient for the subsequent handling of the fireproof boards. At the same time, when the fireproof board is placed, the mounting block at the lower end of the fireproof board will enter the second largest aperture on the upper side of the lower fireproof board to limit the fireproof board to prevent the fireproof board from deflecting during rotation and ensure the stability of rotation.

[0030] Compared with the prior art, the method for manufacturing the bamboo-wood multilayer flame-retardant fireproof board has the following advantages:

[0031] 1. The inventive process of the present invention is scientific and reasonable, which greatly simplifies the structural process of the fireproof board and improves the firmness of the bonding between the layers of the fireproof board, making it difficult for the board layers to fall off, making it easy to stack the fireproof board and also easy to take out later, and having strong practicality.

[0032] 2. During operation, the formed fireproof board body is placed on the conveyor belt, the fireproof board is limited and fixed by the limiting plate, and then the conveyor belt transports the fireproof board body to the bottom of the drilling mechanism, and then the drilling mechanism is used to drill holes on the formed fireproof board body, the drilling positions correspond to the mounting holes on the bottom plate, and the drilling positions include the second large-diameter holes and the second small-diameter holes. After the drilling is completed, the fireproof board body passes through the conveyor belt under the first spraying mechanism, the first spraying mechanism sprays the flame retardant layer on the surface of the bamboo and wood panel, the fireproof board body passes through the conveyor belt under the second spraying mechanism, and then the second spraying mechanism sprays the decorative layer on the surface of the flame retardant layer, and then the processed fireproof board body is placed on the placement rack.

[0033] 3. When spraying the flame retardant layer and the decorative layer, the sealing cover is driven down by the second cylinder so that the lower end of the sealing cover contacts the conveyor belt, and the high-pressure gas source and the feeding pump are turned on. While spraying, the high-pressure gas source and the jet chamber can be used to form a wind curtain around the fireproof board body through the gas, so that the paint will not escape and will not contact the sealing cover, thereby ensuring the quality of spraying and causing no pollution to the sealing cover. It is convenient for long-term use and has good practicality.

[0034] 4. When the processed fireproof board is placed on the rising plate, the electric telescopic rod drives the rising plate to rise. When the fireproof board contacts the supporting plate, it drives the supporting plate to rotate, so that the fireproof board continues to rise. After the fireproof board is separated from the supporting plate, the supporting plate returns to its original position under the action of gravity, and the electric telescopic rod is retracted, and the fireproof board can be placed on the supporting plate. When the next fireproof board rises, the same operation is adopted. At the same time, after the fireproof board rises and contacts the inclined plate, the inclined plate contacts the corner of the fireproof board, and the fireproof board rotates under the action of the inclined plate. Each time a fireproof board is raised, it rotates once, so that adjacent fireproof boards are staggered, which is convenient for the subsequent handling of the fireproof boards. At the same time, when the fireproof board is placed, the mounting block at the lower end of the fireproof board will enter the second largest aperture on the upper side of the lower fireproof board to limit the fireproof board to prevent the fireproof board from offsetting during rotation and ensure the stability of rotation.
