Technical Field

[0001] The invention relates to the technical field of paint spraying equipment, in particular to an automatic paint spraying machine. Background Art

[0002] During the production and processing of wooden doors, they need to be sprayed with paint. The traditional method is for the operator to spray the wooden doors directly with a handheld paint spray gun. This method is labor-intensive and physically demanding, and the paint spray can easily cause damage to the operator's body, and the spraying effect is not good. Therefore, automatic spraying devices have appeared. The automatic spraying machine is controlled by a robotic arm. Compared with manual spraying, the use of automatic spraying machines for spraying operations can improve efficiency, save time, and have better spraying effects, with less harm to construction workers, but its disadvantages are also obvious.

[0003] Since the nozzle of the paint sprayer is connected to the paint barrel through a pipeline, the paint changing process is complicated, which makes the automatic paint sprayer single in specification and only suitable for mass production of products of the same specification. It is not convenient to change colors and paint frequently. If different paint colors need to be sprayed during the work process, the efficiency will be greatly reduced, thereby reducing the practicality of the automatic paint sprayer and bringing inconvenience to the staff.

[0004] For this reason, a kind of automatic painting machine is proposed. Summary of the invention

[0005] The object of the present invention is to provide an automatic paint spraying machine to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: an automatic paint spraying machine, comprising:

[0007] A mechanical arm, wherein a fixing plate is fixedly connected to the lower end of the mechanical arm;

[0008] and: regulating institutions;

[0009] The adjusting mechanism is movably connected to the lower end of the fixing plate, and the adjusting mechanism includes a servo motor, and the servo motor is fixedly connected to the center position of the upper end of the inner surface of the fixing plate;

[0010] A movable plate is fixedly connected to the lower end of the servo motor, and the annular outer surface of the movable plate is rotatably connected to the fixed plate;

[0011] An air gun fixedly connected to the outer surface of the lower end of the movable plate;

[0012] The air jet nozzle is fixedly connected to the outer surface of one end of the air gun.

[0013] Preferably, a plurality of paint spray heads are evenly and slidably connected to the edge of the outer surface of the lower end of the fixed plate, a paint spray nozzle is fixedly connected to the lower end of the paint spray head, a connecting head is fixedly connected to one side of the outer surface of the paint spray head, an electric telescopic rod is provided at one end of the outer surface of the paint spray head away from the connecting head, a connecting rod is fixedly connected to the end of the electric telescopic rod away from the paint spray head, the upper end of the connecting rod is fixedly connected to the fixed plate, and the inner diameter of the connecting head is the same as the outer diameter of the air nozzle.

[0014] Since the automatic paint spraying machine has a single specification, it is only suitable for mass production of products of the same specification, and it is not convenient to change colors and paint frequently. If different paint colors need to be sprayed during the work process, the efficiency will be greatly reduced, thereby reducing the practicality of the automatic paint spraying machine and bringing inconvenience to the staff. The present invention sets an adjustment mechanism. When the paint needs to be changed, the servo motor is started to drive the movable plate to rotate, and the rotation of the movable plate drives the air gun to rotate. When the air gun rotates to a suitable position and stops, the electric telescopic rod connected to the paint nozzle to be sprayed is started, and the electric telescopic rod pushes the paint nozzle to move toward the air nozzle, and the connecting head is connected to the air nozzle. Then the high-pressure gas generated by the air gun is sprayed from the air nozzle, and the paint inside the paint nozzle is sprayed from the paint nozzle to perform the spraying operation. The present invention sets an adjustment mechanism, sets a plurality of paint nozzles, and uses the servo motor to rotate and drive the air gun to rotate, so that the air gun can be connected to multiple paint nozzles, so as to achieve the purpose of convenient and fast paint change of the device, improve the working efficiency and practicality of the device, do not need manual operation by the staff, save the operator's time and labor, and improve the convenience of the device when used.

[0015] Preferably, a connecting block is fixedly connected to one side of the outer surface of the paint spray head near the electric telescopic rod, a groove is provided inside the connecting block, a tilting block is fixedly connected to the bottom end of the inner surface of the groove, the upper outer surface of the tilting block is designed with an inclined structure, one end of the electric telescopic rod is slidably connected to the upper outer surface of the tilting block, a plurality of splints are fixedly connected to the lower outer surface of the fixed plate near the paint spray head, L-shaped grooves are provided on both sides of the inner surfaces of the plurality of splints, two sliding blocks are symmetrically fixedly connected to the outer surfaces of the paint spray head near the L-shaped grooves on both sides, and the sliding blocks are slidably connected to the L-shaped grooves.

[0016] During operation, the present invention sets a tilting block. When the electric telescopic rod is extended, it enters the groove and slides along the upper end of the tilting block, so that the tilting block moves downward under the influence of the squeezing force of the electric telescopic rod, drives the slider to move downward along the L-shaped groove, drives the sliding rod to move downward and disengage from the fixed plate, and when the electric telescopic rod moves to the top of the tilting block, the electric telescopic rod continues to advance, so that the paint spray head moves toward the air nozzle, drives the slider to slide along the L-shaped groove and finally connects the air nozzle with the connecting head. The present invention sets a tilting block and utilizes the sliding connection between the electric telescopic rod and the tilting block to move the paint spray head and the connecting head downward, thereby preventing the paint from contaminating other paint spray heads during spraying.

[0017] Preferably, the electric telescopic rod is fixedly connected to a fixed block at one end away from the connecting rod, and two sliding grooves are symmetrically provided on both sides of the outer surface of the fixed block, and two clamping rods are slidably connected inside the two sliding grooves, and the clamping rods and the sliding grooves are connected by a first spring, and two clamping grooves are symmetrically provided on both sides of the inner surface of the groove near the upper end, and the clamping grooves and the clamping rods match each other.

[0018] When the paint is needed again, the electric telescopic rod is retracted, the rod moves backward along the groove, and the fixed block moves backward accordingly, and the lower end of the fixed block is separated from the tilting block. When the rod moves to the rear end of the inner surface of the groove, the rod will continue to move with the electric telescopic rod, and the connecting block will move backward under the action of the rod, and drive the paint spray head and the connecting head to move to the initial position. The present invention facilitates the movement of the paint spray head and the connecting head to the initial position by the mutual engagement of the groove and the rod.

[0019] Preferably, two first oblique grooves are symmetrically provided on the lower side of the front end outer surface of the connecting block near the two ends of the groove, and the inner diameter of the first oblique groove is the same as the diameter of the clamping rod.

[0020] During operation, the present invention provides a first inclined groove. When the clamping rod moves to the inside of the groove along with the electric telescopic rod, the clamping rod first contacts the inclined surface of the inclined groove and causes it to shrink, thereby facilitating the clamping rod to smoothly enter the groove and engage with the clamping groove.

[0021] Preferably, a second spring is fixedly connected to the outer surface of the upper end of the paint spray head, a slide plate is fixedly connected to the upper end of the second spring, and the slide plate is slidably connected to the fixed plate.

[0022] During operation, the present invention sets a second spring and a slide plate. When the electric telescopic rod contracts and drives the paint spray head to move, the second spring and the slide plate also move accordingly. At the same time, the slider also slides along the horizontal part of the L-shaped groove. When the slider moves to the vertical part of the L-shaped groove, the electric telescopic rod continues to contract, and the card slots are disengaged from each other. The paint spray head moves upward under the elastic force of the second spring and returns to the initial position. By setting the slider and the second spring, the present invention can use the elastic force of the second spring to drive the paint spray head to move upward to the initial position, thereby facilitating the smooth progress of the paint changing work.

[0023] Preferably, a slide rod is fixedly connected to the outer surface of the upper end of the paint spray head at a position located inside the second spring, and the upper end of the slide rod passes through the slide plate and the fixed plate in sequence and is slidably connected to the two.

[0024] During operation, the present invention increases the connection strength between the paint spray head and the slide plate by arranging a sliding rod between the paint spray head and the slide plate, prevents the two from being connected only by the second spring, and prevents the second spring from being deformed when the paint spray head moves, thereby protecting the second spring and increasing the service life of the second spring.

[0025] Preferably, two second oblique grooves are provided on both sides of the inner surface of the groove at the lower end of the clamping groove, and the inner diameter of the second oblique groove is the same as the diameter of the clamping rod.

[0026] When working, the present invention sets the second inclined groove. When the electric telescopic rod is retracted to drive the paint spray head to move, the slider slides along the horizontal part of the L-shaped groove. When the slider moves to the vertical part of the L-shaped groove, the paint spray head moves upward under the elastic force of the second spring, driving the connecting block and the second inclined groove to move upward, so that the clamping rod is separated from the clamping groove along the second inclined groove, and the electric telescopic rod is retracted backward to separate it from the groove. The paint spray head moves upward to the initial position under the elastic force of the second spring. The present invention sets the second inclined groove to facilitate the clamping rod to separate from the clamping groove smoothly, thereby preventing the clamping rod and the clamping groove from being engaged with each other, causing the paint spray head to be unable to move upward.

[0027] Preferably, a sealing groove is formed on the outer surface of one end of the connector away from the paint spray head, and a sealing gasket is fixedly connected to the outer surface of one end of the air nozzle near the sealing groove, and the sealing gasket fits the sealing groove.

[0028] During operation, the sealing groove pad of the present invention is arranged to fit the sealing groove to increase the sealing performance between the paint spray head and the air nozzle, thereby preventing the paint from overflowing from the gap.

[0029] Preferably, the sealing gasket is made of chloroprene rubber and has good corrosion resistance.

[0030] During operation, the sealing gasket is made of chloroprene rubber, which increases the corrosion resistance of the sealing gasket and prolongs the service life of the sealing gasket.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] The present invention provides an adjustment mechanism, provides a plurality of paint spray heads, and utilizes a servo motor to rotate an air gun, so that the air gun can be connected to the plurality of paint spray heads, thereby achieving the purpose of convenient and rapid paint change of the device, improving the working efficiency and practicality of the device, eliminating the need for manual operation by staff, saving the operator's time and labor, and improving the convenience of using the device.

[0054] Since the automatic paint spraying machine has a single specification, it is only suitable for mass production of products of the same specification, and it is not convenient to change colors and paint frequently. If different paint colors need to be sprayed during the work process, the efficiency will be greatly reduced, thereby reducing the practicality of the automatic paint spraying machine and bringing inconvenience to the staff. The present invention sets an adjustment mechanism 3. When the paint needs to be changed, the servo motor 31 is started, thereby driving the movable plate 32 to rotate, and the rotation of the movable plate 32 drives the air gun 33 to rotate. When the air gun 33 rotates to a suitable position and stops, the electric telescopic rod 38 connected to the paint nozzle 35 to be sprayed is started, and the electric telescopic rod 38 pushes the paint nozzle 35 toward the air nozzle 34 The air gun 33 is moved to the left and right sides, and the connecting head 37 is connected to the air nozzle 34. Then the high-pressure gas generated by the air gun 33 is ejected from the air nozzle 34, and the paint inside the paint nozzle 35 is ejected from the paint nozzle 36 to perform the spraying operation. The present invention provides an adjustment mechanism 3, provides a plurality of paint nozzles 35, and utilizes the servo motor 31 to rotate the air gun 33, so that the air gun 33 can be connected to a plurality of paint nozzles 35, so that the device can be used for convenient and fast paint change, thereby improving the working efficiency and practicality of the device, eliminating the need for manual operation by the staff, saving the operator's time and labor, and improving the convenience of the device when used.

[0055] As an embodiment of the present invention, Figures 2 to 4As shown, a connecting block 327 is fixedly connected to one side of the outer surface of the paint spray head 35 near the electric telescopic rod 38, a groove 310 is provided inside the connecting block 327, a tilting block 311 is fixedly connected to the bottom end of the inner surface of the groove 310, the outer surface of the upper end of the tilting block 311 is designed with an inclined structure, one end of the electric telescopic rod 38 is slidably connected to the outer surface of the upper end of the tilting block 311, a plurality of splints 312 are fixedly connected to the outer surface of the lower end of the fixing plate 2 near the paint spray head 35, L-shaped grooves 314 are provided on both sides of the inner surfaces of the plurality of splints 312, two sliding blocks 313 are symmetrically fixedly connected to the positions near the L-shaped grooves 314 on both sides of the outer surface of the paint spray head 35, and the sliding blocks 313 are slidably connected to the L-shaped grooves 314.

[0056] During operation, the present invention sets a tilting block 311. When the electric telescopic rod 38 is extended, it enters the groove 310 and slides along the upper end of the tilting block 311, so that the tilting block 311 moves downward under the squeezing force of the electric telescopic rod 38, driving the slider 313 to move downward along the L-shaped groove 314, driving the slide bar 324 to move downward and disengage from the fixed plate 2. When the electric telescopic rod 38 moves to the top of the tilting block 311, the electric telescopic rod 38 continues to advance, so that the paint spray head 35 moves toward the air nozzle 34, driving the slider 313 to slide along the L-shaped groove 314 and finally connecting the air nozzle 34 with the connecting head 37. The present invention sets a tilting block 311 and utilizes the sliding connection between the electric telescopic rod 38 and the tilting block 311 to move the paint spray head 35 and the connecting head 37 downward, thereby preventing the paint from contaminating other paint spray heads 35 during spraying.

[0057] As an embodiment of the present invention, Figure 2 , Figure 5 and Figure 6 As shown, one end of the electric telescopic rod 38 away from the connecting rod 39 is fixedly connected to a fixed block 315, and two sliding grooves 316 are symmetrically provided on both sides of the outer surface of the fixed block 315, and two clamping rods 317 are slidably connected inside the two sliding grooves 316, and the clamping rods 317 are connected to the sliding grooves 316 by a first spring 318, and two clamping grooves 319 are symmetrically provided on both sides of the inner surface of the groove 310 near the upper end, and the clamping grooves 319 and the clamping rods 317 are consistent with each other.

[0058] During operation, the present invention sets the clamping rod 317 and the clamping slot 319. When the electric telescopic rod 38 enters the groove 310, the clamping rod 317 contacts the inner wall of the groove 310 and shrinks into the slide groove 316. When the electric telescopic rod 38 continues to advance and drives the fixed block 315 to move to the top of the tilting block 311, the clamping rod 317 moves to the corresponding position of the clamping slot 319. The clamping rod 317 pops out of the slide groove 316 and engages with the clamping slot 319 under the elastic force of the first spring 318. When it is necessary to change the paint again, the electric telescopic rod 38 is retracted. The clamping rod 317 moves backward along the clamping slot 319, and the fixed block 315 moves backward accordingly, and the lower end of the fixed block 315 is separated from the tilting block 311. When the clamping rod 317 moves to the rear end of the inner surface of the clamping slot 319, the clamping rod 317 will continue to move with the electric telescopic rod 38, and the connecting block 327 will move backward under the action of the clamping rod 317, and drive the paint spray head 35 and the connecting head 37 to move to the initial position. The present invention facilitates the movement of the paint spray head 35 and the connecting head 37 to the initial position by engaging the clamping slot 319 with the clamping rod 317.

[0059] As an embodiment of the present invention, Figure 5 As shown, two first inclined grooves 320 are symmetrically provided at the lower side of the front end outer surface of the connecting block 327 near the two ends of the groove 310 , and the inner diameter of the first inclined groove 320 is the same as the diameter of the clamping rod 317 .

[0060] During operation, the present invention sets a first inclined groove 320. When the clamping rod 317 moves to the inside of the groove 310 along with the electric telescopic rod 38, the clamping rod 317 first contacts the inclined surface of the inclined groove and causes it to shrink, thereby facilitating the clamping rod 317 to smoothly enter the groove 310 and engage with the clamping groove 319.

[0061] As an embodiment of the present invention, Figure 2 As shown, the outer surface of the upper end of the paint spray head 35 is fixedly connected with a second spring 321 , the upper end of the second spring 321 is fixedly connected with a slide plate 322 , and the slide plate 322 is slidably connected to the fixed plate 2 .

[0062] During operation, the present invention sets the second spring 321 and the slide plate 322. When the electric telescopic rod 38 contracts to drive the paint spray head 35 to move, the second spring 321 and the slide plate 322 also move accordingly, and the slider 313 also slides along the horizontal part of the L-shaped groove 314. When the slider 313 moves to the vertical part of the L-shaped groove 314, the electric telescopic rod 38 continues to contract, and the slots 319 are separated from the slots 319. The paint spray head 35 moves upward under the elastic force of the second spring 321 and returns to the initial position. The present invention sets the slider 313 and the second spring 321, and the elastic force of the second spring 321 can be used to drive the paint spray head 35 to move upward to the initial position, thereby facilitating the smooth progress of the paint changing work.

[0063] As an embodiment of the present invention, Figure 2 As shown, the upper outer surface of the paint spray head 35 is fixedly connected to a slide bar 324 at a position located inside the second spring 321, and the upper end of the slide bar 324 passes through the slide plate 322 and the fixed plate 2 in sequence and is slidably connected to the two.

[0064] During operation, the present invention increases the connection strength between the paint nozzle 35 and the slide plate 322 by setting a slide rod 324 between the paint nozzle 35 and the slide plate 322, thereby preventing the two from being connected only by the second spring 321. When the paint nozzle 35 moves, the second spring 321 will be deformed, thereby protecting the second spring 321 and increasing the service life of the second spring 321.

[0065] As an embodiment of the present invention, Figure 5 As shown, two second inclined grooves 323 are provided on both sides of the inner surface of the groove 310 at the lower end of the clamping groove 319 , and the inner diameter of the second inclined groove 323 is the same as the diameter of the clamping rod 317 .

[0066] During operation, the present invention provides the second inclined slot 323. When the electric telescopic rod 38 contracts and drives the paint spray head 35 to move, the slider 313 slides along the horizontal part of the L-shaped slot 314. When the slider 313 moves to the vertical part of the L-shaped slot 314, the paint spray head 35 moves upward under the elastic force of the second spring 321, driving the connecting block 327 and the second inclined slot 323 to move upward, so that the clamping rod 317 is separated from the clamping slot 319 along the second inclined slot 323, and the electric telescopic rod 38 is retracted backward to separate from the groove 310. The paint spray head 35 moves upward to the initial position under the elastic force of the second spring 321. The present invention provides the second inclined slot 323 to facilitate the clamping rod 317 to smoothly separate from the clamping slot 319, thereby preventing the clamping rod 317 and the clamping slot 319 from being engaged with each other, causing the paint spray head 35 to be unable to move upward.

[0067] As an embodiment of the present invention, Figure 2 and Figure 7 As shown, a sealing groove 325 is formed on the outer surface of one end of the connector 37 away from the paint spray head 35 , and a sealing gasket 326 is fixedly connected to the outer surface of one end of the air nozzle 34 near the sealing groove 325 , and the sealing gasket 326 and the sealing groove 325 fit each other.

[0068] During operation, the sealing groove 325 pad of the present invention is arranged to fit the sealing groove 325 to increase the sealing performance between the paint spray head 35 and the air nozzle 34, thereby preventing the paint from overflowing from the gap.

[0069] As an embodiment of the present invention, Figure 2 As shown, the sealing gasket 326 is made of chloroprene rubber and has good corrosion resistance.

[0070] During operation, by making the sealing gasket 326 out of chloroprene rubber, the corrosion resistance of the sealing gasket 326 is increased, and the service life of the sealing gasket 326 is prolonged.

[0071] Instructions for use: The present invention is provided with an adjustment mechanism 3. When the paint needs to be replaced, the servo motor 31 is started, thereby driving the movable plate 32 to rotate. The rotation of the movable plate 32 drives the air gun 33 to rotate. When the air gun 33 rotates to a suitable position and stops, the electric telescopic rod 38 connected to the paint nozzle 35 to be sprayed is started. The electric telescopic rod 38 extends into the groove 310 and slides along the upper end of the tilting block 311, so that the tilting block 311 moves downward under the squeezing force of the electric telescopic rod 38, driving the slider 313 to move downward along the L-shaped groove 314, driving the slide bar 324 to move downward and detach from the fixed plate 2. When the electric telescopic rod 38 moves to the tilting position, the slide bar 324 moves downward and detaches from the fixed plate 2. When the electric telescopic rod 38 reaches the top of the inclined block 311, the electric telescopic rod 38 continues to advance, so that the paint spray head 35 moves toward the air nozzle 34, driving the slider 313 to slide along the L-shaped groove 314 and finally connecting the air nozzle 34 with the connecting head 37. Then, the high-pressure gas generated by the air gun 33 is ejected from the air nozzle 34, and the paint inside the paint spray head 35 is ejected from the paint spray nozzle 36 to perform the spraying operation. By setting the clamping rod 317 and the clamping groove 319, when the electric telescopic rod 38 enters the groove 310, the clamping rod 317 first contacts the inclined surface of the inclined groove and shrinks to the inside of the slide groove 316. When the electric telescopic rod 38 continues to advance and drives the fixed block 315 to move to the inclined block 311 When the paint is needed again, the electric telescopic rod 38 is retracted, and the rod 317 moves backward along the slot 319. At the same time, the fixed block 315 moves backward accordingly, and the lower end of the fixed block 315 is separated from the inclined block 311. When the rod 317 moves to the rear end of the inner surface of the slot 319, the rod 317 will continue to move with the electric telescopic rod 38, and the connecting block 327 will move backward under the action of the rod 317, and drive the paint spray head 35 and the connecting head 37 to move backward. When the electric telescopic rod 38 contracts and drives the paint spray head 35 to move, the second spring 321 and the slide plate 322 also move accordingly, and the slider 313 also slides along the horizontal part of the L-shaped groove 314. When the slider 313 moves to the vertical part of the L-shaped groove 314, the paint spray head 35 moves upward under the elastic force of the second spring 321, driving the connecting block 327 and the second inclined groove 323 to move upward, so that the clamping rod 317 is separated from the clamping groove 319 along the second inclined groove 323, and the electric telescopic rod 38 is retracted backward to separate it from the groove 310. The paint spray head 35 moves upward to the initial position under the elastic force of the second spring 321.
