Description

Technical Field

[0001] The invention belongs to the field of wood flooring, and in particular relates to a double water-based process wood flooring which is sprayed with water-based paint and pressed with water-based glue. Background Art

[0002] Double water-based wood flooring refers to the process of cutting out multiple large boards of wood flooring, including base board and veneer, with a large board area of ​​about 3 square meters. The base board and veneer are fixed with water-based glue. The large board is cut, slotted, sanded and polished to obtain the blank board of wood flooring. The blank board is smoked, discolored and painted to obtain the finished product. Double water-based means that water-based glue is used to glue the base board and veneer, and water-based paint is used for painting. The characteristics of double water-based wood flooring are environmental protection and low odor.

[0003] Compared with oil-based glue, water-based glue is more environmentally friendly and has less odor, but the construction requirements are also higher. When using oil-based glue, you can even wait for the oil-based glue to dry before pressing the substrate and veneer together, which will not reduce the bonding strength. However, when using water-based glue, it is generally required to press the substrate and veneer together immediately. The longer the delay, the lower the bonding strength. Once dry, bonding cannot be achieved. In the existing process, the water-based glue nozzle is placed on the substrate and / or veneer, and then the substrate and veneer are pressed together. There is a long period of material transfer time in the middle, including the centering time of the substrate and veneer, which will cause the moisture in the water-based glue to be absorbed by the substrate or veneer, thereby drying faster, reducing the bonding strength, resulting in poor moisture and heat resistance and cold and heat cycle resistance of the wooden floor surface. In the subsequent use process, delamination, peeling, cracking, bubbling and other phenomena are prone to occur. Of course, there are some water-based glues on the market with special ingredients added, which can keep the substrate and veneer with a high bonding strength for a long time after spraying, but the cost of this kind of glue is relatively high.

[0004] After polishing, the blank board is smoked and discolored in a fumigation and color-changing room to make the surface color saturated with high color saturation, and the color and layering will also be improved. The main steps are to place the blank board in the fumigation and color-changing room and place ammonia water in the fumigation and color-changing room. The ammonia water will evaporate naturally to form smoke. The smoke contacts the blank board to change the color of the blank board, but the smoke concentration formed in the air by the volatilization of ammonia water is low, resulting in a long time for the blank board to change color, which will reduce the production efficiency of the wood floor. In addition, ammonia water is very smelly and has certain toxicity. There are safety hazards for workers to enter and exit the fumigation and color-changing room to take and place the blank boards. If the fumigation and color-changing room is ventilated first, the next batch of smoke-changing will take a long time for the ammonia water to evaporate, which will further reduce the production efficiency. Therefore, it is generally not ventilated, but the workers wear protective clothing to enter and exit the fumigation and color-changing room. Wearing protective clothing takes time, and wearing protective clothing is not conducive to flexible work, which will also reduce production efficiency.

[0005] In summary, the existing double water-based process wood flooring with water-based paint spraying and water-based glue pressing has the defects of low bonding strength, low production efficiency and certain safety hazards during production. Summary of the invention

[0006] The purpose of the present invention is to provide a double water-based process wood flooring which is sprayed with water-based paint and pressed with water-based glue.

[0015] In the aforementioned double water-based process wood flooring of water-based paint spraying and water-based glue pressing, the method of using the pressing device is:

[0016] First, place the substrate on the feeding end of the conveyor, and make the length of the substrate parallel to the conveying direction of the conveyor, and the front end of the substrate is located below the guide roller;

[0017] Then put the veneer on the base plate, use quick-drying glue to glue the back end of the veneer to the base plate, and place the front end of the veneer on the guide roller;

[0018] Start the conveyor and the sprayer at the same time, turn off the sprayer when all the substrates pass through the nozzle, and turn off the conveyor when all the substrates pass through the pressure roller.

[0019] In the aforementioned double water-based process wood flooring with water-based paint spraying and water-based glue pressing, in the step c, a spray mechanism is provided on the top of the fumigation and color-changing room;

[0020] At least two parallel long pits are arranged on the floor of the fumigation color changing room, and the two ends of the long pits extend to the outside of the two ends of the length of the fumigation color changing room respectively.

DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0038] c. The blank board is first smoked and discolored, then sprayed with polyurethane water-based primer (transparent). After the polyurethane water-based primer dries, it is polished, and then sprayed with polyurethane water-based topcoat (transparent) to obtain the finished wood flooring.

[0039] The finished product was tested by the Inspection Laboratory of the Institute of Wood Industry, Chinese Academy of Forestry, based on GB / T41547-2022 and T / CNFPIA 1003-2022, and the results are shown in Table 1.

[0040] Table 1

[0041]

[0042] Embodiment 2 In step a of embodiment 1, the veneer 2 and the substrate 1 are pressed together in a pressing device, and the pressing device comprises a roller conveyor 3, and the rollers on the conveyor 3 are rubber rollers with high friction.

[0043] A guide roller 4 is provided above the conveyor 3, and both ends of the guide roller 4 are fixed to the frame of the conveyor 3. A plurality of nozzles 5 for spraying water-based glue downward are provided at the bottom of the guide roller 4. The nozzles 5 are connected to a sprayer through a hose (the sprayer can be connected to a spraying device commonly used for existing water-based glue). The sprayer can be placed on the ground or fixed on the frame of the conveyor 3. The hose preferably passes through the inside of the guide roller. Two pressure rollers 7 that can be raised and lowered are provided on the rear side of the guide roller 4.

[0044] Support plates 8 are provided on both sides of the frame of the conveyor 3 , and bearings 9 are provided between the support plates 8 and the pressure roller 7 , and the inner ring of the bearing 9 is fixed to the pressure roller 7 .

[0045] The support plate 8 is provided with a guide long hole 10, the width of the guide long hole 10 matches the outer diameter of the bearing, the guide long hole 10 is vertically arranged, and limit plates 11 are provided on both sides of the guide hole. The limit plates 11 are fixed to the outer ring of the bearing 9, and the limit plates 11 limit the axial movement of the bearing 9.

[0046] The method of using the pressing device:

[0047] First, the substrate 1 is placed on the feeding end of the conveyor 3 , and the length direction of the substrate 1 is parallel to the conveying direction of the conveyor 3 , and the front end of the substrate 1 is located below the guide roller 4 .

[0048] Then, the veneer 2 is placed on the base plate 1 in a centered manner, the rear end of the veneer 2 is glued to the base plate 1 with quick-drying glue, and the front end of the veneer 2 is placed on the guide roller 4 .

[0049] Start the conveyor 3 and the sprayer at the same time. The substrate 1 passes under the guide roller 4, and the sprayer drives the water-based glue to be sprayed from the nozzle 5 onto the substrate 1, and the spraying action begins. The veneer passes from the upper side of the guide roller 4. Since the veneer is thin and soft, the front end of the veneer will sag until it fits with the substrate 1, and then pass from under the pressure roller 7. The pressure roller 7 will rise a short distance (about 0.5mm is better) under the reaction force, and the veneer 2 is pressed onto the substrate 1 by the deadweight of the pressure roller 7, and the pressing action begins. The subsequent spraying and pressing are carried out simultaneously until the substrate 1 passes through the nozzle 5, the sprayer is turned off, and the nozzle 5 stops discharging glue, saving glue and avoiding workshop pollution. When the substrate 1 passes through the pressure roller 7, the conveyor 3 is turned off to obtain a large board.

[0050] The large board is transferred to the ground and left to stand for a period of time to allow the glue to cure completely. You can also stack several large boards together to form a stack, and place some more boards on the stack to increase the load, which can make the glue cure better.

[0051] The purpose of gluing at the rear end of the veneer 2 is to transfer the driving force of the substrate 1 to the veneer 2 so that the veneer can pass through the guide roller 4 smoothly. At the same time, the bonding force between the substrate and the veneer is not too large. When the rear end of the substrate is about to pass under the guide roller, the glue point position can automatically collapse. Taking a substrate with a width of 1.2 meters as an example, two to three glue points are sufficient. The number of glue points can be adjusted on site according to the adhesive strength of the quick-drying glue used.

[0052] The pressing device can realize spraying and pressing at the same time during the large panel production process, leaving less time for glue to volatilize, thus achieving a good pressing effect.

[0053] Embodiment 3. On the basis of embodiment 2, the long guide hole 10 is changed into a round hole, so that the height of the pressure roller 7 is fixed and cannot be raised or lowered, an elastic rubber sleeve is arranged on the outer peripheral surface of the pressure roller 7, a reduction motor is arranged at one end of the pressure roller 7, the output end of the reduction motor is connected to the pressure roller 7, the housing of the reduction motor is fixed to the support plate 8 through a bracket, the reduction motor rotates the pressure roller 7, and the linear speed of the pressure roller 7 matches the conveying speed of the conveyor 3. When the large board passes under the pressure roller 7, the deformation of the rubber sleeve generates elastic force to press the veneer 2 onto the base plate 1, and at the same time, the rubber sleeve gives the large board forward power.

[0054] Compared with Example 2 and Example 3, Example 2 has a relatively simple structure and lower cost. It relies on the deadweight of the pressure roller 7 to press the veneer. The weight of the pressure roller 7 cannot be too large, otherwise it will offset the forward friction force given to the large board by the conveyor, causing the large board to stop moving forward. The lack of pressing force will reduce the pressing effect to a certain extent. Example 3 is more complicated and more expensive than Example 2, but because the rubber sleeve on the pressure roller 7 itself will give the large board forward power, it can also give the veneer 2 greater pressure, which will improve the pressing effect to a certain extent, and can keep the large board moving at a more uniform speed, and the glue spraying is more uniform, so that the pressing effect is better.

[0055] Example 4. In step c of Example 1, the green sheet is smoked and discolored in the fumigation and color changing room 12, and ammonia water spray is used to form high-concentration smoke in the fumigation and color changing room 12 to accelerate the speed of smoke discoloration of the green sheet.

[0056] A spray mechanism 13 is provided on the top of the fumigation color changing room 12. The spray mechanism 13 can be purchased from the market, and the more thorough the atomization, the better, such as using an ultrasonic atomizer.

[0057] The floor of the fumigation and color changing room 12 is provided with three parallel long pits 14, the two ends of the long pits 14 respectively extend to the outside of the two ends of the length of the fumigation and color changing room 12, and a conveyor 24 is provided in the long pit 14. The conveyor 24 adopts a plate chain conveyor, and the conveying surface of the conveyor 24 is flush with the floor of the fumigation and color changing room 12;

[0058] The fumigation color changing room 12 is provided with a plurality of shelves arranged side by side, the shelves are used to place a plurality of blanks, the long direction of the shelves is perpendicular to the conveying direction of the conveyor 24, and three rows of universal wheels 15 are provided at the bottom of the shelves, and the three rows of universal wheels 15 are respectively located on the conveying surfaces of the three conveyors 24, and the number of universal wheels 15 in each row of universal wheels 15 is two;

[0059] A feed door 16 and a discharge door 17 are provided on the width side of the fumigation and color changing room 12, and the feed door 16 and the discharge door 17 are respectively close to the two ends of the length direction of the fumigation and color changing room 12, and an air curtain machine 23 connected to the fumigation and color changing room 12 is provided on the upper side of the feed door 16 and the upper side of the discharge door 17. When the feed door 16 or the discharge door 17 is opened, the air curtain machine 23 can isolate the air circulation inside and outside the fumigation and color changing room 12, and reduce the leakage of ammonia smoke to the outside.

[0060] The shelf includes a bottom plate 18, a universal wheel 15 fixed on the bottom of the bottom plate 18, two support plates 19 arranged in an eight-shaped shape are fixed on the top surface of the bottom plate 18, and a plurality of baffles 20 arranged from top to bottom are arranged on the outer surface of the support plate 19, the baffles 20 are horizontally oriented, and a plurality of anti-slip rods 22 extending upward are arranged on the baffles 20, and a handle 21 is provided between the two support plates 19, and pulling the handle 21 provides a force point for the movement of the shelf.

[0061] The method of using the fumigation color changing room 12 includes the following steps:

[0062] First move all the shelves outside the fumigation and color changing room 12.

[0063] Place the blank horizontally on the baffle 20 of the shelf, and tilt the blank against the backing plate 19, with the use surface of the blank (corresponding to the upper surface of the wooden floor) facing outward. Taking a 1.2-meter-long blank as an example, 4 blanks are placed on one baffle 20, and the total length of the shelf is 4.85-4.9 meters.

[0064] After the loading of the shelf is completed, the shelf is transferred to the fumigation and color changing room 12, specifically, the feed door 16 is opened, the air curtain machine 23 above the feed door 16 is started, and the shelf is pushed into the fumigation and color changing room 12 from the feed door 16. The universal wheels 15 at the bottom of the shelf are correspondingly located on the conveyor 24, and the conveyor 24 is started for a period of time to move the shelf toward the discharge door 17 for a certain distance to avoid the feed door 16, and then the next shelf is pushed in, and the operation is repeated until all the shelves enter the fumigation and color changing room 12. Since the conveyor 24 can eliminate the gaps between the shelves, the space utilization rate of the fumigation and color changing room 12 is high, and the floor space of the fumigation and color changing room 12 can be reduced on the basis of fumigating the same number of blanks.

[0065] Close the feed door 16 and the corresponding air curtain machine 23.

[0066] Start the spray mechanism 13, which atomizes the ammonia water and transports it to the fumigation and color changing room 12 to change the color of the blank. According to the smoke concentration in the fumigation and color changing room 12, the spray speed is flexibly adjusted. The basic idea is to spray with a large flow rate first, and then switch to a small flow rate after the concentration reaches a certain value. The small flow rate plays a role of consumption and supplementation. No spraying is required in the last stage.

[0067] After fumigation is completed, the spray mechanism 13 is closed, the discharge door 17 and the air curtain machine 23 above the discharge door 17 are opened, and the shelves are pulled out from the discharge door 17 in sequence. Each time a shelf is pulled out, the conveyor 24 is started for a period of time to allow the next shelf to reach the discharge door 17, until all the shelves are moved out, the discharge door 17 and the air curtain machine 23 above the discharge door 17 are closed, and the fumigated blanks are removed from the shelves.

[0068] The advantages of the fumigation color change room are: 1) It can provide high-concentration smoke to fumigate the blanks, reducing the time required for the blanks to change color and improving production efficiency; 2) Workers do not need to enter the fumigation color change room to avoid ammonia poisoning and eliminate safety hazards; 3) Workers do not need to wear protective clothing, which makes their work more flexible, further improving production efficiency and reducing labor intensity, especially in summer when wearing protective clothing will be very stuffy; 4) The space utilization rate is high, which can reduce the floor space of the fumigation color change room.
