Description
Technical Field
[0001] The invention relates to the technical field of wood wax oil spraying, in particular to furniture wood wax oil coating equipment. Background Art
[0002] Boards are one of the commonly used forms of wood for furniture. When furniture boards are produced, they need to go through processes such as cutting, grinding and polishing, carving and painting. Wood wax oil is a commonly used paint for solid wood boards. Wood wax oil applied to boards can effectively protect the wood from sunlight, moisture and pollution, enhance the beauty and texture of the wood, and at the same time has waterproof and moisture-proof functions, simplifying daily cleaning and maintenance. It is an environmentally friendly and effective wood protection and decorative material.
[0003] In order to improve the automation level of wood wax oil spraying on wooden boards, workers will place wooden boards on conveyor belts, which will be transported to the paint spraying room along the conveyor belt, and the nozzle will spray wood wax oil onto the wooden boards. In order to make the wood wax oil sprayed on the wooden boards more evenly and densely, the nozzle is at a distance from the wooden boards in the paint spraying room, which also causes part of the wood wax oil to spray out of the range of the wooden boards and fall on other wooden boards. This will undoubtedly add an extra layer of wood wax oil to the previous or next wooden boards, resulting in uneven spraying of the wood wax oil on the wooden boards. Directly increasing the distance between adjacent wooden boards on the conveyor belt will undoubtedly increase the transmission time of the wooden boards, thereby reducing the spraying efficiency of the wooden boards.

DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0021] like Figures 1 to 5 As shown, the present invention includes the following embodiments: Example
[0022] A furniture wood wax oil coating equipment comprises a frame 1 and a conveyor belt 2 driven on the frame 1; a spray chamber 3 is fixedly connected to the upper middle section of the conveyor belt 2; a spray head 41 is arranged in the spray chamber 3; the spray head 41 is connected to the material box 31 at the top of the spray chamber 3 through a hose 32; a spray box 5 is connected to the spray chamber 3 for sliding up and down; the lower end of the spray box 5 is an opening; the inner wall of the spray box 5 is slidingly connected to the spray plate 4; the spray head 41 is evenly fixedly connected to the lower surface of the spray plate 4; the top of the spray chamber 3 is fixedly connected to a cylinder 33; the output shaft of the cylinder 33 extends to the inside through the top of the spray chamber 3, and the output shaft of the cylinder 33 extends to the inside through the top of the spray box 5; the output shaft of the cylinder 33 is fixedly connected to the upper surface of the spray plate 4; the top projection of the lower port of the spray box 5 covers the parts to be sprayed.
[0023] During operation, the staff will put the wooden boards on the upper surface of the conveyor belt 2 in turn, and start the controller. The controller can be understood as the control system of all the coating equipment. The controller will control the conveyor belt 2 to work, and the conveyor belt 2 will drive the wooden boards to enter the spraying room 3 in turn. After the wooden boards to be sprayed move to just below the spraying box 5, the conveyor belt 2 stops working, and the controller will control the cylinder 33 to extend and drive the spraying plate 4 to move downward. During the downward movement of the spraying plate 4, the nozzle 41 will be driven downward, and the spraying box 5 will also be driven downward during the downward movement of the spraying plate 4. The spraying box 5 is slidably connected to the inner wall of the spraying room 3, so the spraying box 5 can move downward along the inner wall of the spraying room 3, and the spraying box 5 will move downward during the downward movement. The wooden board to be sprayed is covered, and the lower end of the spray box 5 contacts the upper surface of the conveyor belt 2, so that the lower end of the spray box 5 is blocked, and then the cylinder 33 controls the spray plate 4 to move down to a corresponding height according to the thickness of the wooden board, and then the nozzle 41 is started to work. The nozzle 41 will spray the wood wax oil in the hose 32, and the wood wax oil is sprayed from the nozzle 41 and flies to the wooden board to be sprayed in the form of mist at a certain height, so that the upper surface of the wooden board to be sprayed is evenly covered with the wood wax oil. In addition, due to the shielding of the spray box 5, the nozzle 41 will not splash to the adjacent wooden boards during the process of spraying the wood wax oil, so that only the current wooden board is sprayed, thus avoiding the adjacent wooden boards during the spraying process of the wooden board to be sprayed The wood wax oil on the wooden board is affected by the spraying, so that each wooden board can be sprayed independently without affecting each other, thereby making the wood wax oil spraying on the wooden board more uniform. In addition, when the wooden board is sprayed by the spray head 41, the mist of wood wax oil is confined in the spray box 5 and is difficult to fly to the outside, reducing the pollution to the air around the spray room 3. After one of the wooden boards has completed the spraying of wood wax oil, the controller will control the cylinder 33 to shorten and drive the spray plate 4 to move upward. During the upward movement of the spray plate 4, the spray head 41 will be driven upward. The spray box 5 maintains contact with the conveyor belt 2 under the action of its own gravity. As the spray plate 4 moves upward, the upper surface of the spray plate 4 contacts the bottom wall of the spray box 5. The spray box 5 will move along The spraying box 5 moves upward along with the upward movement of the spraying plate 4, so that the spraying box 5 is separated from the contact with the conveyor belt 2 after moving upward, so that the sprayed wooden board is exposed, and then the conveyor belt 2 will drive the next wooden board to move to the right below the spraying box 5, and the next wooden board will be sprayed, and the wooden board that has been sprayed will be conveyed to the next position along the conveyor belt 2. A drying box is provided in the spraying room 3, and the drying box is close to the outlet of the spraying room 3. The wooden board enters from the entrance of the spraying room 3 and moves out from the outlet. The drying box is located between the spraying box 5 and the outlet of the spraying room 3, so that the drying box can dry the wood wax oil on the wooden board that has been sprayed, so that the dried wooden board is moved out of the spraying room 3, and this is repeated; The present invention covers the wooden boards on the conveyor belt 2 by the spray box 5, so that the spray head 41 will not affect the adjacent wooden boards during the process of spraying wood wax oil, so that the wooden boards on the conveyor belt 2 can be sprayed independently, making the wood wax oil coating on the wooden boards more uniform. Example 1
[0024] The conveyor belt 2 is connected to the inner side of the frame 1 through a roller 11; the inner side of the conveyor belt 2 is supported by the roller 11; a receiving box 6 is provided on the inner side of the conveyor belt 2 and directly below the spray box 5; the inner cross-section of the receiving box 6 is adapted to the inner cross-section of the spray box 5; the receiving box 6 is fixedly connected to the frame 1; and through holes 21 are provided on the inner and outer sides of the conveyor belt 2.
[0025] In this embodiment, the spray plate 4 is slidably sealed to the inner wall of the spray box 5; the spray plate 4 is penetrated by one-way air outlet holes 42; the inner bottom wall of the spray box 5 is penetrated by one-way air inlet holes 51; the inner bottom wall of the spray box 5 and the upper surface of the spray plate 4 are connected by a tension spring 52.
[0026] In this embodiment, the conveyor belt 2 is made of elastic material; the conveyor belt 2 can be concave toward the other side after being pressed on one side.
[0027] During operation, after the conveyor belt 2 drives the wooden board to move to the bottom of the spray box 5, the conveyor belt 2 stops driving, and the controller controls the cylinder 33 to extend to drive the spray plate 4 to move downward. During the downward movement of the spray plate 4, the spray box 5 is pulled downward by the tension spring 52. After the spray box 5 moves downward, it will press against the outer surface of the conveyor belt 2 under its own gravity and the tension of the tension spring 52. Then, the spray plate 4 continues to move downward under the extension of the cylinder 33. The spray plate 4 divides the internal space of the spray box 5 into an upper cavity and a lower cavity. The nozzle 41 is located in the lower cavity. As the spray plate 4 moves downward, the gas in the lower cavity is pressurized and moves along the conveyor belt 2. The gas in the lower chamber is discharged through the through hole 21. Since the spray plate 4 moves downward in the spray box 5 at a relatively fast speed, the gas in the lower chamber is discharged along the through hole 21 at a limited speed. In this way, a certain degree of gas pressure is formed in the lower chamber. The position of the conveyor belt 2 in contact with the spray box 5 will be depressed downward under the action of the gas pressure in the lower chamber. The spray box 5 is pressed against the upper surface of the conveyor belt 2 under the tension of the tension spring 52, thus ensuring the sealing of the lower chamber. The upper surface of the conveyor belt 2 is more likely to be depressed downward. The wooden board on the upper surface of the conveyor belt 2 will move toward the depressed low point of the conveyor belt 2 during the depression of the conveyor belt 2, thereby achieving the goal of The position of the board on the upper surface of the conveyor belt 2 is adjusted, so that the position of the wooden board under the spray box 5 is adjusted, so that the position of the wooden board being sprayed is more accurate, and the coating effect of the wood wax oil on the wooden board is improved; when the lower chamber has a certain air pressure, the spray plate 4 is also moved to a suitable height, and the nozzle 41 starts to work. The nozzle 41 will use the hose 32 to absorb the wood wax oil in the material box 31. As the wood wax oil is sprayed by the nozzle 41, the wood wax oil is sprayed into a mist by the nozzle 41, so that the mist of the wood wax oil falls on the surface of the wooden board under its own gravity and its own kinetic energy. After the nozzle 41 stops working, the cylinder 3 3 further extends, so that the gas pressure in the lower cavity is further increased. During the increase of the gas pressure in the lower cavity, the wood wax oil can better penetrate into the interior of the wooden board, thereby improving the coating effect of the wood wax oil. In addition, for some hollow carved wooden boards, especially for wooden boards with small hollow carvings, as the lower cavity is compressed, the gas in the lower cavity will pass through the small hollows on the wooden board and the through holes 21 on the conveyor belt 2, and the excess wood wax oil at the hollow position of the wooden board will be taken away by the airflow, thereby preventing some small hollows from forming an oil film solidified under the action of more wood wax oil, thereby improving the coating effect of the wood wax oil on the wooden board with carvings;During the downward movement of the spray plate 4, the gas in the upper chamber will expand, allowing external gas to enter the upper chamber along the one-way air inlet 51 for replenishment. As the spray plate 4 moves down to the limit position, the spray plate 4 will move up under the shortening of the cylinder 33. During the upward movement of the spray plate 4, it will be close to the bottom wall of the spray box 5. The tension spring 52 keeps pulling the spray box 5. After the spray plate 4 moves up, the space in the upper chamber is compressed, and the gas in the upper chamber will be discharged along the one-way air outlet 42. The one-way air outlet 42 will blow the gas downward. The airflow will blow the painted surface of the board, so that the excess wood wax oil is blown away. In addition, the mist wood wax oil in the lower chamber is also blown away with the airflow. The airflow will pass through the through hole 21 on the conveyor belt 2 to reduce the excess wood wax oil remaining on the conveyor belt 2 and the board. The wood wax oil will fall into the receiving box 6 and be collected for subsequent recycling. As the spraying plate 4 repeatedly moves up and down, the excess wood wax oil on the board and the mist wood wax oil in the lower chamber are discharged, thereby improving the wood wax oil coating effect on the board and improving the cleanliness of the spraying area above the conveyor belt 2. ; Example 2
[0028] The receiving box 6 is provided with a replacement groove 61 in the width direction of the conveyor belt 2; the replacement groove 61 passes through the frame 1; a replacement frame 62 is provided in the replacement groove 61; a sponge 63 is provided in the replacement frame 62; the misted wood wax oil entering the receiving box 6 will contact the sponge 63 inside the replacement frame 62.
[0029] In this embodiment, the side wall of the material receiving box 6 and located below the replacement groove 61 is connected to a return pipe 64; the other end of the return pipe 64 passes through the spray chamber 3 and is connected to the one-way air inlet hole 51 on the inner bottom wall of the spray box 5; the return pipe 64 is made of elastic material.
[0030] In this embodiment, a circular groove 65 is provided at the upper end of the material receiving box 6; a circular sleeve 66 is slidably connected in the circular groove 65; the lower end of the circular sleeve 66 is connected to the bottom of the circular groove 65 by a spring 67; the upper end of the circular sleeve 66 contacts the conveyor belt 2 under the action of the spring 67.
[0031] In this embodiment, the diameter of the through hole 21 is smaller than the thickness of the circular sleeve 66 ; and the distance between adjacent through holes 21 is greater than the thickness of the circular sleeve 66 .
[0032] During operation, after the conveyor belt 2 drives the wooden board to move to the bottom of the spray box 5, the downward movement of the spray plate 4 will pull the tension spring 52 to drive the spray box 5 to fall on the upper surface of the conveyor belt 2. In the initial state, the spring 67 will give the return sleeve 66 a force away from the return groove 65, so that the return sleeve 66 is pressed against the inner side of the conveyor belt 2 under the elastic force of the spring 67, thereby maintaining a close contact between the inner side of the conveyor belt 2 and the receiving box 6. The position of the return sleeve 66 against the inner side of the conveyor belt 2 corresponds to the position of the lower end of the spray box 5 against the upper surface of the conveyor belt 2, so that the spraying area of the conveyor belt 2 is clamped. After the spray head 41 completes the spraying of the wood wax oil, the spray plate 4 will move down and up back and forth. During the downward movement of the spray plate 4, the gas in the lower chamber will be rushed to the wooden board, and the excess wood wax oil on the wooden board and the misted wood wax oil in the lower chamber will enter the inner side of the receiving box 6 along the through hole 21. The gas will drive the wood wax oil to be filtered by the sponge 63, and the sponge 63 will absorb the wood wax oil. The filtered gas will enter the upper chamber along the reflux pipe 64, thereby reducing the resistance of the spray plate 4 to move downward, improving the use effect of the coating equipment, and the gas in the receiving box 6 is not easy to leak out under the action of the circular sleeve 66, ensuring the surrounding spraying environment. Clean, after a period of use of the sponge 63, the replacement frame 62 is pulled out from the replacement slot 61, and a new sponge 63 is loaded into the replacement slot 61 along with the replacement frame 62 to complete the replacement of the sponge 63. The wood wax oil on the disassembled sponge 63 can be recycled; in the process of adjusting the position of the wooden board by the depression on the upper surface of the conveyor belt 2, the conveyor belt 2 will be deformed, and the spring sleeve 66 cooperates with the spray box 5 under the action of the spring 67 to achieve a tight clamping of the conveyor belt 2 to prevent the gas in the receiving box 6 and the lower cavity from leaking out; in addition, the aperture and spacing of the through hole 21 are limited It is also to prevent the gas in the receiving box 6 from leaking out, further improve the sealing of the receiving box 6 and the lower cavity, so that the wood wax oil on the wooden board is impacted by the circulating airflow, and the airflow will disperse the wood wax oil on the wooden board. If the oxygen content in the airflow is high, it will accelerate the solidification of the wood wax oil. In this way, the solidification of the wood wax oil on the wooden board is reduced by the reflux airflow, so that the wood wax oil on the wooden board can be evenly blown away, the engraving position can be prevented from being blocked, and the excess wood wax oil can be discharged before solidification. The wood wax oil on the conveyor belt 2 can also be stripped off before solidification to avoid clogging of the through hole 21 and affect the next use effect.
