Description

Technical Field

[0001] The invention relates to the field of painting processing equipment for wood boards, and in particular to a processing device for wood boards. Background Art

[0002] In the process of processing wooden ornaments, wood boards are usually used as raw materials for processing. During the processing, the wood boards need to be painted to make the finished products beautiful. The existing wood board painting device usually includes a conveyor and a paint spray head. The paint spray head cannot adjust the painting range of the wood board, so that the painting device can only be used for painting wood boards of a certain fixed width specification. As a result, the processing of the wood board is limited, the practicality is not high, and the efficiency of actual production and processing is affected. Summary of the invention

[0003] The present invention is intended to provide a processing device for wooden boards, so as to solve the problem that the spraying range of the paint spray head cannot be adjusted, realize the painting processing of wooden boards of different width specifications, and enhance the practical effect of the device.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a processing device for wooden boards, including a conveying platform and a paint box, the paint box is connected to a paint spraying tube, the paint spraying tube is connected to a paint spraying head, the paint spraying head is located above the conveying platform, the paint spraying head includes a main nozzle and an auxiliary nozzle, the main nozzle is located in the auxiliary nozzle, the width of the main nozzle is smaller than that of the auxiliary nozzle, and a paint spraying branch pipe is arranged on the main nozzle, and the paint spraying branch pipes all pass through the auxiliary nozzle; a hair dryer is also arranged above the conveying platform; a plurality of through holes arranged in sequence along the width direction of the conveying platform are provided on the conveying platform, the hair dryer is located directly above the through hole, and an air bag is connected to one end of the through hole away from the hair dryer, and the air bag Exhaust ports are provided on the top, an air flow channel for air flow is provided under the conveying platform, a slide groove is provided at the bottom of the air flow channel, the length direction of the slide groove is the same as the arrangement direction of the multiple through holes, an arc-shaped spring piece that simultaneously resists the multiple air bags is provided in the air flow channel, both ends of the spring piece are slidably connected in the slide groove; the two ends of the air flow channel are respectively connected with an air inlet pipe and an air outlet pipe, a partition is provided in the air outlet pipe and the air outlet pipe is divided into an upper air outlet pipe and a lower air outlet pipe by the partition, a pressure valve is provided at one end of the upper air outlet pipe close to the air flow channel, and airflow-driven paint spraying mechanisms are connected between the lower air outlet pipe and the main nozzle, as well as between the upper air outlet pipe and the auxiliary nozzle.

[0005] The principle of this scheme is: in actual application, the conveyor table is used to place the wooden board to be processed, and the paint spray head is used to spray the paint in the paint box onto the wooden board through the paint spray tube to realize the painting process. The spray head includes a main spray head and an auxiliary spray head. The main spray head is used to spray paint on narrower wooden boards, and the auxiliary spray head is used to spray paint on wider wooden boards, so that the device can process wooden boards of different widths. The through hole is used to inject the airflow blown out by the hair dryer into the airbag, so that the airbag is inflated and expands to squeeze the shrapnel, so that the shrapnel is in a straight state. When the wooden board is placed on the conveyor table for processing, the wooden board blocks the through hole on the conveyor table, so that part of the airbag is not inflated and the squeezing effect on the shrapnel is reduced. When the width of the wooden board is larger, the number of through holes that are blocked is greater, and thus the number of air bags that do not expand is greater. At this time, after the shrapnel loses part of the extrusion of the air bags, it can return to an arc state under the action of its own elastic potential energy and block part of the space in the air flow channel, thereby limiting the direction of the air flow and increasing the air pressure, causing the air flow to impact the pressure valve and enter the upper air outlet duct, and be blown out by the upper air outlet duct to trigger the air flow-driven paint spraying mechanism connected to the upper air outlet duct, thereby realizing the painting work of the auxiliary nozzle, thereby realizing the painting process of the wider wooden board.

[0006] The advantages of this solution are:

[0007] 1. By using wooden boards of different widths to block the through holes to different degrees, the shrapnel can be released to different degrees, so that the shrapnel can restore the arc state and block part of the space in the air flow channel. As a result, the air flow can only be blown into the upper air outlet duct through the upper part of the air flow channel, thereby triggering the auxiliary paint spraying pipe to automatically spray paint the wooden board within an adaptive range, thereby enhancing the practical effect of the device.

[0008] 2. The bending of the spring is used to block the airflow, so that the airflow can forcefully impact the pressure valve and enter the upper air outlet duct, and the airflow has sufficient kinetic energy to drive the corresponding airflow-driven spraying mechanism to start working quickly and effectively, thereby realizing the rapid adjustment and use of the auxiliary nozzle to ensure comprehensive and effective painting of the wooden board.

[0009] Preferably, as an improvement, a main spray pipe is connected between the main spray head and the paint box, an auxiliary spray pipe is connected between the auxiliary spray head and the paint box, and the airflow-driven spray painting mechanism includes valves rotatably arranged on the main spray pipe and the auxiliary spray pipe, the valves are both installed with reset torsion springs, and the valves are both fixedly connected with impellers, the outer sides of the impellers are both covered with shells, the shells are fixed on the main spray pipe and the auxiliary spray pipe, the lower air outlet pipe is connected to the inner part of the shell on the main spray pipe, and the upper air outlet pipe is connected to the inner part of the shell on the auxiliary spray pipe. When the spring piece is straight, the airflow is blown out through the airflow channel, at which time the air pressure is small and the pressure valve is in a closed state, so the airflow can only be discharged from the lower air outlet pipe, and impact the impeller on the main spray pipe through the lower air outlet pipe, so that the impeller rotates to open the main spray pipe, and the main spray head sprays paint to process the wood board. When the spring becomes an arc, the air flow channel becomes narrower. At this time, the air flow can only flow along the gap between the spring and the air flow channel, so the air pressure in the air flow channel becomes larger. When the air flow flows to the pressure valve, the larger air pressure impacts the pressure valve and opens it. At this time, the air flow is discharged through the upper air outlet pipe and impacts the impeller on the auxiliary paint spray pipe, causing the impeller to rotate and drive the valve to rotate, thereby opening the auxiliary paint spray pipe. At this time, the auxiliary nozzle starts to spray paint and paints the wider wooden board, thereby realizing automatic conversion of the main nozzle and the auxiliary nozzle, which is convenient for actual processing operations.

[0010] Preferably, as an improvement, baffles are provided on both sides of the conveying platform, and a cavity connected to the air inlet pipe is provided inside one of the baffles, and a plurality of air inlet holes connected to the cavity are provided on the baffle. When the hair dryer blows air toward the conveying platform, the airflow is blocked by the conveying platform and diffuses everywhere, and enters the cavity through the air inlet holes, and then blows into the air flow channel through the air inlet pipe, so as to realize the control of the bending change of the spring piece, thereby making multi-faceted use of the airflow of the hair dryer and reducing the energy consumption of the device.

[0011] Preferably, as an improvement, a dust collecting plate is provided on the other baffle plate facing the air inlet hole. When the airflow is blocked by the conveying platform and diffuses and flows around, the dust on the wooden board is blown off and adhered to the dust collecting plate, thereby achieving the purpose of effective dust removal.

[0012] Preferably, as an improvement, bristles are provided on the dust collecting plate. When the airflow blows onto the bristles, the bristles rub against each other to generate static electricity, thereby enhancing the adsorption effect on dust and improving the dust removal quality.

[0013] Preferably, as an improvement, a dust removal pipe is provided at the lower side of the air inlet channel, and an elastic surface and a fixed surface are provided on the dust removal pipe. A pulling arm is connected between the elastic surface and the spring sheet, and one end of the dust removal pipe is connected to a fan, and the other end extends to the conveying platform with the pipe opening facing the dust suction plate. The wider the width of the wooden board to be processed, the greater the degree of release of the spring sheet, the more bent the spring sheet, and thus the greater the degree to which the spring sheet moves and drives the elastic surface to deform. Therefore, when processing a wider wooden board, the air volume and air pressure blown onto the wooden board by the dust removal pipe are also greater, so that the dust on the part of the wooden board far away from the pipe opening of the dust removal pipe can also be effectively blown away, thereby ensuring the dust removal effect on the wooden board and improving the processing quality of the wooden board.

[0019] The conveying platform 1 is used to place the wood board to be processed. A blower 7 is arranged above the conveying platform 1. The conveying platform 1 is provided with six through holes 5 arranged in sequence in a transverse direction. The blower 7 is located directly above the through holes 5.

[0020] The airflow driven paint spraying mechanism is used to spray paint on wooden boards of different widths under the driving action of airflow, and its structure includes a paint box 2, the paint box 2 is welded with a main paint spraying pipe and an auxiliary paint spraying pipe connected, the main paint spraying pipe is bolted and fixedly connected with a main spray head 3, and the auxiliary paint spraying pipe is bolted and fixedly connected with an auxiliary spray head 4, the main spray head 3 is located inside the auxiliary spray head 4, the width of the main spray head 3 is smaller than that of the auxiliary spray head 4, and the main spray head 3 is provided with a paint spraying branch pipe, and the paint spraying branch pipes all pass through the auxiliary spray head 4 and extend to the conveying platform 1. Valves are rotatably provided on the main paint spraying pipe and the auxiliary paint spraying pipe through bearings, and reset torsion springs are installed on the valves, and impellers 14 are fixedly connected to the valves through shaft keys, and the outer sides of the impellers 14 are covered with shells, and the two shells are respectively welded to the main paint spraying pipe and the auxiliary paint spraying pipe.

[0021] The airflow control mechanism is used to control the operation of the airflow-driven paint spraying mechanism so that the main nozzle 3 and the auxiliary nozzle 4 are automatically switched for use. The airflow control mechanism includes six airbags 6 bonded to the lower ends of the six through holes 5, and each of the airbags 6 is provided with an exhaust port. An airflow channel 8 for airflow is provided below the conveyor 1, and a horizontal chute 9 is provided at the bottom of the airflow channel 8. The chute 9 is provided with a flange. An arc-shaped spring sheet 10 that simultaneously abuts against the six airbags 6 is provided in the airflow channel 8. Both ends of the spring sheet 10 are connected with a clamping column, and the clamping column is clamped in the chute 9 by the flange, thereby realizing a sliding connection between the spring sheet 10 and the chute 9. The two ends of the air flow channel 8 are respectively connected to an air inlet pipe 11 and an air outlet pipe. The air inlet pipe 11 is connected to the cavity on the baffle 15. The air outlet pipe is divided into an upper air outlet pipe 12 and a lower air outlet pipe 13 by a partition. A pressure valve is provided at one end of the upper air outlet pipe 12 close to the air flow channel 8. The upper air outlet pipe 12 is connected to the outer shell on the auxiliary paint spray pipe, and the lower air outlet pipe 13 is connected to the outer shell on the main paint spray pipe.

[0022] The dust removal mechanism is used to remove dust on the surface of the wooden board. The structure includes a fan 19 and a dust removal pipe 17 connected to the fan 19. Figure 2 As shown, the dust removal pipe 17 is provided with an elastic surface 18 and a fixed surface 20 connected to each other, and a pull arm is provided between the elastic surface 18 and the spring sheet 10, one end of the pull arm is bonded and fixed to the elastic surface 18, and the other end is rotatably connected to the spring sheet 10 through a positioning pin. The end of the dust removal pipe 17 away from the fan 19 extends to the conveying platform 1 and the pipe opening faces the dust suction plate 16.

[0023] In this embodiment, in actual application, the wood board to be processed is placed on the conveying platform 1, and the wood board is controlled by the conveying mechanism to move and convey on the conveying platform 1. The blower 7 works to blow air toward the conveying platform 1, and the air flow is blown into the through hole 5 and flows into the air bag 6, so that the air bag 6 is inflated. The exhaust port of the air bag 6 slowly exhausts the air bag 6. At this time, the air bag 6 expands and presses the spring sheet 10 to make it straight, and the air flow channel 8 is fully opened. At the same time, part of the air flow is blocked by the conveying platform 1 and diffuses everywhere, and blows into the cavity through the air inlet hole, and then blows into the air flow channel 8 through the air inlet pipe 11 connected to the cavity. The air flow flows in the air inlet channel. At this time, the air pressure is relatively low, and the pressure valve cannot be opened. Therefore, the air flow is only discharged from the lower air outlet pipe 13 and blown into the outer shell on the main paint spraying pipe, thereby driving the impeller 14 on the main paint spraying pipe to rotate and drive the valve to rotate and open, so that the main nozzle 3 works to spray paint the narrow wood board.

[0024] When the width of the wooden board to be processed is large, after the wooden board is placed on the conveying table 1, more through holes 5 are blocked by the wooden board. At this time, most of the air bags 6 are blocked by the wooden board and cannot take in air. Therefore, the squeezing effect of these air bags 6 on the spring pieces 10 becomes smaller, and the spring pieces 10 are subjected to less squeezing force and return to the bent state. At this time, the two ends of the spring piece 10 slide close together in the slide groove 9. When the spring piece 10 bends into the air flow channel 8, the air flow channel 8 is separated and the air flow channel is reduced. At this time, the air flow can only flow through the gap between the spring piece 10 and the top wall of the air flow channel 8, so that the air pressure accumulates in the air flow channel 8 and increases the air pressure. At the same time, the bent part of the spring piece 10 raises the outflow direction of the air flow, so that the air flow flows out directly towards the upper air outlet pipe 12. At this time, the pressurized air flow directly impacts the pressure valve, and the pressure valve is opened due to a large pressure, and the air flow is blown out through the upper air outlet pipe 12. At this time, the air flow of the lower air outlet pipe 13 is reduced, and the impeller 14 corresponding to the lower air outlet pipe 13 stops driving the valve to rotate, and the valve on the main paint spray pipe rotates in the opposite direction under the action of the torsion spring to reset and stop the main spray head 3 from spraying paint. At this time, after the air flow is blown into the outer shell of the auxiliary paint spray pipe through the upper air outlet pipe 12, it pushes the impeller 14 in the outer shell of the auxiliary paint air pipe to rotate, and the impeller 14 drives the valve on the auxiliary paint spray pipe to rotate and open the auxiliary paint spray pipe, so that the auxiliary nozzle 4 can spray paint the wide wooden board.

[0025] When the fan 19 is working, it blows air to the wooden board on the conveying platform 1 through the dust removal pipe 17, and blows the dust on the wooden board to the dust collection plate 16 to improve the painting quality of the wooden board. The bristles on the dust collection plate 16 rub against each other under the blowing of the airflow and carry static electricity, thereby enhancing the adsorption effect of dust. When spraying paint on a wider wooden board, the spring 10 pulls the elastic surface 18 on the dust removal pipe 17 away from the fixed surface 20 through the pulling arm during the bending process, so that the diameter of the dust removal pipe 17 increases and the air flow of the fan 19 to the wooden board increases, so that the dust on the part of the wooden board away from the pipe mouth of the dust removal pipe 17 can also be effectively blown away, achieving the purpose of comprehensive and efficient cleaning.

[0026] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
