[0046] Existing background technology:

[0047] 1. Due to the large order volume and many specifications of solid wood veneer wood grilles, mass production is required. For example, in Example 1, the wood grille specifications are 200mm wide and 570mm high. The wood grille strips are 5mm deep and 10mm wide, and the distance between the wood grille strips is 20mm.

[0048] 2. Existing technology: Use 2440mm*1220mm*5mm double-laminated solid wood MDF to cut along the grain with a sliding table saw (the saw blade is a diamond saw blade; thickness 3.5mm; speed 26m / min) to cut out 2440mm*10mm*5mm wooden grille strips, and then cross-cut 570mm to a final size of 570mm*10mm*5mm. At this time, the wooden grille strips have 2 sides that need to be manually edge-sealed, and the width of the edge-sealing strips is 8mm. At this time, edge-sealing is difficult and takes about 10 minutes. (The glue is top force, model 8250 woodworking wood veneer universal glue, the best temperature is 15-25 degrees) One wooden grille requires six wooden grille strips, that is, each wooden grille product takes about 1 hour. After each wooden grille is sealed and brushed with veneer glue, it is placed according to the wooden grille position (the size between wooden grilles is 20mm according to the order requirements), and then pressed with a press plate of about 10 kg.

[0049] 3. It takes about 20 minutes for the pressing plate to press the wooden grille. Check whether there is glue overflowing on both sides of the wooden grille. If there is glue overflowing, wait for 2 hours (the glue has solidified to a certain extent) and use a glue block to remove the excess glue.

[0050] 4. Manual edge sealing: Since the width of the wooden grille is 10mm and the depth is 5mm, the depth of the wooden grille is small and the spacing is also small, it is not easy to seal the edges on both sides, it is easy to overflow glue, it is difficult to clean the glue, and there is a risk of being cut by a blade at the edge sealing.

[0051] 5. White blank polishing: clean the glue, glue the bad parts of the edge with glue in time, and then polish with 320# sandpaper, and the final effect is to achieve burr-free and smooth surface;

[0052] 6. Spraying sealing primer: spray two crosses evenly, no sagging, no oil accumulation, paint ratio 1:0.2:0.2, brand Sherwin-Williams, paint number is substrate sealer PS900-3.5; curing agent GAR02-10; thinner PU815 odor-free thinner.

[0053] 7. Primer polishing: Use 320# sandpaper to polish evenly, with no exposed bottom and no particles.

[0054] 8. Spray primer: spray evenly in two crosses, without sagging and oil accumulation, the paint ratio is 1:0.15:0.6; brand Sherwin-Williams, paint number is PU yellowing resistant transparent primer PD1800, PU yellowing resistant curing agent PR18A-3.5, thinner PX815;

[0055] 9. Primer polishing: Use 320# sandpaper to polish evenly, with no exposed bottom and no particles.

[0056] 10. Color correction: The two crosses are evenly colored, with no sag or oil accumulation. The paint ratio is 1:0.15:1. The paint brand is Sherwin-Williams. The paint number is PU one-color matte yellowing-resistant clear topcoat PU18001-18, PU yellowing-resistant curing agent PR18A-3.5, and thinner PX815;

[0057] 11. Surface polishing: Manual polishing, use 1000# sandpaper to evenly polish the surface of the board. The standard is that it cannot be worn through and there should be no particles.

[0058] 12. Topcoat spraying: Spray the two crosses evenly. There should be no sag, particles, oil accumulation, orange peel and other defects.

[0059] 13. After the panel is sprayed with topcoat, put it in the drying room to wait for the surface to dry, then put it in the baking room for 8 hours. Lightly scratch the surface of the panel with your finger as long as there is no scratch.

[0060] Cost accounting:

[0061] 1. According to this method, each person can paste one wooden grille per hour, which is about 8 per day.

[0062] 2. Labor cost: 8 pieces / person ÷ 8 hours = 1 piece / person / hour.

[0063] 200 yuan / person / day ÷ 8 hours / day = 25 yuan / person / hour.

[0064] 25÷1=1 piece of wood grille veneer costs 25 yuan

[0065] 3. Time cost: 1 hour

[0066] 4. Quality cost: If one out of 50 pieces is unqualified, that is 1÷50×100%=2%, which means there is a 2% loss. 2% saving = 25 yuan for processing + material cost.

[0067] Disadvantages of this process and problems that need to be solved:

[0068] 1. The order volume of wooden grilles is large, and pure handmade production can no longer meet the order cycle.

[0069] 2. Manual edge banding: Since the width of the wooden grille strip is 10mm and the depth is ultra-thin 5mm, the wooden grille strip is small, it is not easy to seal the edge, it is easy to overflow glue, it is difficult to clean, and there is a risk of being cut by the blade at the edge. High cost saving.

[0070] 3. Each person can paste one wooden grille per hour, which is about 8 per day, with low production capacity and labor efficiency.

[0071] 4. The time cost is too long.

[0072] 5. The wooden grille bars are of different specifications and are difficult to operate.

The connection design installs a conveyor belt and a clamp between the sliding table saw and the edge banding machine, and the two ends of the conveyor belt are equipped with set sensors. When the board is cut, the sensor will start the conveyor belt and the clamp. When the clamp clamps the board to ensure that it remains stable during the edge banding process, the clamp is released when the edge banding is completed, and the conveyor belt rollers are arranged obliquely to transport the board to the edge banding machine and keep the board close to the edge banding side. The conveyor belt transports the board to the set position. This design adopts a PLC control system to realize the linkage control of the edge banding machine and the sliding table saw. The PLC control system can automatically start, stop, adjust the speed and other functions. At the same time, it has a fault self-diagnosis function to detect and solve problems in time. Edge banding machine settings: PUR glue heater temperature (160° in summer and 180° in winter), glue coating amount between 130 g / m2 and 150 g / m2; brand: Yongtenai, model: 60930.

[0130] 2. Cutting plan of sliding table saw Cut the whole board with edge banding into wooden grille strips with specifications of 2440mm*10mm*5mm (the saw blade is a diamond saw blade; thickness 3.5mm; speed 26m / min). At this time, the sliding table saw has set the cutting size. The cutting time of sliding table saw is about 20 seconds. After the sensor senses the cutting of the board, it starts the conveyor belt and the clamp (the clamp can set the closing size according to the size of the board) to transport the board to the edge banding machine for edge banding. When the board arrives at the edge banding machine, the sensor starts the edge banding machine for edge banding. After the edge banding is completed, the sensor starts the conveyor belt to transport the board to the sliding table saw. At this time, the sensor starts the sliding table saw for cutting.

[0131] 3. Use 13mm edge banding strips to band the right side of the 2440mm*1220mm*10mm double-laminated technology veneer MDF using an edge banding machine. Each edge banding takes 20 seconds and the length is 2440mm. Then place the board neatly with the edge facing outwards for the next step.
