Description

Technical Field

[0001] The invention relates to the technical field of automatic painting, and in particular to an environmentally friendly automatic building painting device. Background Art

[0002] Automatic spray painting is a kind of paint that is processed by special methods and then filled with high pressure for easy spraying. Spray paint has a wide range of uses. Through the economic development in recent years, its uses have developed from repairing paint defects to various industries such as molds, industrial machinery, toys, handicrafts, musical instruments, buildings, steel structures, advertising and publicity, signs, graffiti, etc., and even in grassland pastoral areas with a low degree of industrialization. Nowadays, the use of spray paint in building decoration has gradually replaced the traditional painting method, because spray paint not only has the advantages of short construction period and can improve the work efficiency of workers, but also the walls after spraying have the advantages of good flatness, comfortable touch and texture.

[0003] At present, workers generally spray paint by swinging a handheld nozzle up and down, but this method has high labor intensity, and manual reciprocating spraying is not uniform.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] Example 1: Reference Figure 1-8 , an environmentally friendly building automatic painting device, comprising a mobile base 1, and also comprising:

[0038] A lifting part 2, the lifting part 2 is fixed on the movable base 1, and a nozzle 3 is arranged on the lifting part 2;

[0039] A material supply assembly, which is disposed on the mobile base 1 and is used to supply paint spraying material to the spray head 3; and

[0040] The adjusting mechanism includes a first adjusting component connected to the lifting part 2 and a second adjusting component arranged on the first adjusting component, and is used to adjust the spraying direction of the spray head 3, and the spray head 3 is arranged on the second adjusting component;

[0041] The second adjusting component is also provided with a suction hopper 4, and the suction hopper 4 is connected to a fan device arranged on the mobile base 1 through a pipeline.

[0042] Furthermore, the feeding assembly includes a material box 5 fixed on the mobile base 1, the discharge end of the material box 5 is connected to the first hose 501 through the pump body, the end of the first hose 501 is connected to the straight pipe 502, the end of the straight pipe 502 away from the first hose 501 is connected to the second hose 503, and the end of the second hose 503 away from the straight pipe 502 is connected to the nozzle 3 arranged on the second adjustment assembly.

[0043] Specifically, during operation, the nozzle 3 is moved to the front side of the wall to be sprayed through the mobile base 1. At this time, the nozzle 3 is slightly higher than the ground and faces the wall. Because the nozzle 3 sprays radially, the paint can be sprayed on the lower side of the wall. Then the feeding assembly and the lifting part 2 are controlled to work, and the material box 5 provides paint to the nozzle 3 through the pipeline. The lifting part 2 drives the nozzle 3 to spray paint on the wall from bottom to top in sequence. The fan equipment can collect the paint that is not attached to the wall sprayed by the nozzle 3 through the suction hopper 4 to avoid polluting the air or being absorbed by the human body. The wall is sprayed with paint during the upward movement of the nozzle 3 When the nozzle 3 is moved upwards, the adjustment mechanism automatically adjusts the distance between the nozzle 3 and the wall and the spraying direction of the nozzle 3 to the wall, so that the nozzle 3 can spray paint on the lowest and highest sides of the wall during the up and down reciprocating motion, thereby ensuring that the nozzle 3 sprays paint on the wall comprehensively, without the need for staff to spray again later, thereby reducing the workload of staff and ensuring the painting efficiency. At the same time, the nozzle 3 always maintains the same distance from the wall during the up and down reciprocating painting process, thereby ensuring the same spray angle and spray force of the paint to the wall without changing the output power, so that the paint is evenly sprayed on the wall, ensuring the painting effect.

[0044] Example 2: Reference Figure 1-3 , an environmentally friendly building automatic painting device, based on Example 1, further, the lifting part 2 includes a support base 201 fixed on the mobile base 1, and the support base 201 is provided with a first motor 202. The output shaft of the first motor 202 passes through the support base 201 and is connected to a screw 203 rotating between the support base 201 and the mobile base 1. The screw 203 is provided with a sleeve 204, and the first adjusting component is connected to the sleeve 204.

[0045] Specifically, when the lifting part 2 is working, the first motor 202 is controlled to run, and the output shaft of the first motor 202 drives the screw 203 to rotate. When the screw 203 rotates, the sleeve 204 moves along its axial direction, and then the sleeve 204 drives the adjustment mechanism and the nozzle 3 on the adjustment mechanism to move up and down, so as to achieve full spraying of the wall from top to bottom.

[0046] Example 3: Reference Figure 1-7 , an environmentally friendly building automatic painting device, based on Example 2, further, the first adjusting component includes a second motor 6 fixedly mounted on the sleeve 204, the output shaft of the second motor 6 is connected to a rotating rod 601, the end of the rotating rod 601 away from the sleeve 204 is connected to a rotating seat 602, the straight tube 502 is slidably connected to the rotating seat 602, a fixed plate 5021 is fixed on the straight tube 502, and an elastic element 5022 is sleeved on the outer side of the straight tube 502, whose two ends are respectively connected to the fixed plate 5021 and the rotating seat 602, and the end of the straight tube 502 away from the first hose 501 is connected to the second adjusting component.

[0047] Furthermore, a support plate 7 is fixedly provided on the sleeve 204, and a first winding rod 701 is rotatably connected to the support plate 7. A first pull rope 702 is wound around the first winding rod 701. One end of the first pull rope 702 away from the first winding rod 701 passes through the sleeve 204 and is connected to the fixed plate 5021. A first gear 7011 is fixedly provided on the first winding rod 701, and an arc-shaped rack frame 6021 meshing with the first gear 7011 is provided on the rotating seat 602.

[0048] Specifically, when performing the painting operation, since the nozzle 3 is initially at the bottom of the device and slightly higher than the ground, the nozzle 3 can spray paint on the bottom of the wall. As the lifting part 2 works, the nozzle 3 moves from bottom to top, and the second motor 6 is controlled to operate. The output shaft of the second motor 6 drives the rotating seat 602 to rotate through the rotating rod 601, and the rotating seat 602 drives the straight tube 502 to rotate, so that the straight tube 502 drives the nozzle 3 connected to its end to lift up, so that the height of the subsequent nozzle 3 is not lower than the height of the screw 203, which is convenient for the nozzle 3 to spray paint on the top of the wall; when the rotating seat 602 rotates, the arc-shaped rack on the bottom side of the rotating seat 602 The frame 6021 meshes with the first gear 7011 on the first winding rod 701 for transmission, the first winding rod 701 winds up the first pull rope 702, and the first pull rope 702 applies tension to the fixed plate 5021, so that the straight tube 502 moves horizontally in the rotating seat 602, so that the straight tube 502 approaches the wall, and makes up for the distance loss of the nozzle 3 connected at the end away from the wall due to the flipping of the straight tube 502, so that the nozzle 3 always maintains the same distance from the wall during the up and down reciprocating painting process, and then on the basis of not changing the output power of the paint spraying, the same spray force of the paint spraying material onto the wall is guaranteed, so that the paint is evenly sprayed on the wall, and the painting effect is guaranteed.

[0049] Example 4: Reference Figure 1-8 , an environmentally friendly building automatic painting device, based on Example 3, further, the second adjustment component includes a connecting seat 8 fixedly connected to the straight pipe 502, the connecting seat 8 is rotatably connected to a rotating shaft 801, the rotating shaft 801 is fixedly provided with a first swing plate 802, the first swing plate 802 is slidably connected to a second swing plate 803, the two ends of the second swing plate 803 are respectively rotatably connected to a first rotating rod 804 and a second rotating rod 805, and the nozzle 3 is connected to the second rotating rod 805.

[0050] Furthermore, a main gear 6011 is provided on the rotating rod 601, a transmission rod 9 is fixed on the sleeve 204, a sub-gear 901 meshing with the main gear 6011 is provided on the transmission rod 9, a first synchronous wheel 10 is provided on the transmission rod 9 and the rotating shaft 801, and a first synchronous belt is provided between the two first synchronous wheels 10.

[0051] Specifically, the second adjustment component is composed of a first swing plate 802 and a second swing plate 803. When the second motor 6 drives the straight tube 502 to rotate clockwise through the rotating seat 602, so that the end of the straight tube 502 close to the wall is lifted, the main gear 6011 on the rotating rod 601 is meshed with the sub-gear 901 on the transmission rod 9 for transmission, so that the sub-gear 901 drives the transmission rod 9 to rotate counterclockwise, and the transmission rod 9 drives the rotating shaft 801 to rotate counterclockwise through the first synchronous wheel 10 and the first synchronous belt, so that the second adjustment component drives the nozzle 3 to rotate downward, thereby ensuring that the nozzle 3 always maintains the same angle with the wall during the up and down reciprocating painting process, and then on the basis of not changing the output power of the paint spraying, the spray angle of the paint to the wall is the same, so that the paint is evenly sprayed on the wall, ensuring the painting effect.

[0052] Example 5: Reference Figure 1-11 , an environmentally friendly building automatic painting device, based on Example 4, further, a U-shaped seat 11 is slidably connected to the first swing plate 802, and a third motor 111 is fixed on the U-shaped seat 11 for driving the first rotating rod 804 to rotate, and the first swing plate 802 is rotatably connected to the second winding rod 806 at one end away from the first rotating rod 804, and the first rotating rod 804 and the second winding rod 806 are both provided with a second synchronous wheel 12, and a second synchronous belt is provided between the two second synchronous wheels 12, and the second winding rod 806 is wound with a second pull rope 8061, and the second pull rope 8061 is connected to the second swing plate 803 at one end away from the second winding rod 806.

[0053] Furthermore, a second gear 8041 is provided on the first rotating rod 804, a gear ring 13 meshing with the second gear 8041 is rotatably connected to the U-shaped seat 11, a third rotating rod 14 is rotatably connected to the second swing plate 803, a third gear 141 meshing with the gear ring 13 is provided on the third rotating rod 14, a third synchronous wheel 15 is provided on the third rotating rod 14 and the second rotating rod 805, and a third synchronous belt is provided between the two third synchronous wheels 15.

[0054] Furthermore, the gear ring 13 includes a gear ring 131 and an inner gear ring 132 and an outer gear ring 133 arranged on both sides of the gear ring 131 . The second gear 8041 is meshedly connected to the inner gear ring 132 , and the third gear 141 is meshedly connected to the outer gear ring 133 .

[0055] Specifically, during the painting operation, the nozzle 3 is initially at the bottom of the device and slightly above the ground, so that the nozzle 3 can spray paint on the bottom of the wall. As the lifting part 2 works, the third motor 111 is controlled to operate, so that the output shaft of the third motor 111 drives the first rotating rod 804 to rotate. When the first rotating rod 804 rotates, it drives the second swing plate 803 to rotate relative to the first swing plate 802. The first rotating rod 804 drives the second winding rod 806 to rotate through the second synchronous wheel 12 and the second synchronous belt. The second winding rod 806 winds up the second pull rope 8061. The second pull rope 8061 pulls the U-shaped seat 11 and makes it slide on the first swing plate 802, so that the second swing plate 803 flips upward and drives the nozzle 3 close to the wall. At the same time, the second pull rope 8061 pulls the second swing plate 803 away from the wall, so that the nozzle 3 reciprocates up and down in the process of spraying paint. During the process, the same distance from the wall is always maintained, and the same spraying force of the paint material onto the wall is ensured without changing the output power of the paint spraying, so that the paint material is evenly sprayed on the wall to ensure the painting effect. When the second gear 8041 on the first rotating rod 804 rotates, it meshes with the inner gear ring 132 of the gear ring 13 for transmission. The gear ring 13 rotates and meshes with the third gear 141 through the outer gear ring 133 for transmission. The third rotating rod 14 connected to the third gear 141 drives the second rotating rod 805 to rotate through the third synchronous wheel 15 and the third synchronous belt. The second rotating rod 805 drives the nozzle 3 to rotate in the opposite direction to the second swing plate 803, so as to ensure that the nozzle 3 is always facing the wall during the painting operation, and the same spraying angle of the paint material onto the wall is ensured without changing the output power of the paint spraying, so that the paint material is evenly sprayed on the wall to ensure the painting effect.

[0056] Working principle: During operation, the nozzle 3 is moved to the front side of the wall to be sprayed through the mobile base 1. At this time, the nozzle 3 is slightly higher than the ground and faces the wall. Because the nozzle 3 sprays radially, the paint can be sprayed on the lowest side of the wall. Then the feeding assembly and the lifting part 2 are controlled to work, and the material box 5 provides paint to the nozzle 3 through the pipeline. The first motor 202 is controlled to operate. The output shaft of the first motor 202 drives the screw 203 to rotate. The sleeve 204 moves along its axial direction when the screw 203 rotates, so that the sleeve 204 drives the adjustment mechanism and the nozzle 3 on the adjustment mechanism to move up and down. The lifting part 2 drives the nozzle 3 to spray paint on the wall from bottom to top. The fan equipment can collect the paint that is not attached to the wall sprayed by the nozzle 3 through the suction bucket 4 to avoid polluting the air or being absorbed by the human body.

[0057] Initially, the nozzle 3 is at the bottom of the device and slightly above the ground, so that the nozzle 3 can spray paint on the bottom of the wall. As the lifting part 2 works, the third motor 111 is controlled to run, so that the output shaft of the third motor 111 drives the first rotating rod 804 to rotate. When the first rotating rod 804 rotates, it drives the second swing plate 803 to rotate relative to the first swing plate 802. The first rotating rod 804 drives the second winding rod 806 to rotate through the second synchronous wheel 12 and the second synchronous belt. The second winding rod 806 winds up the second pull rope 8061. The second pull rope 8061 pulls the U-shaped seat 11 and makes it slide on the first swing plate 802, so that the second swing plate 803 flips upward to drive the nozzle 3 close to the wall. At the same time, the second pull rope 8061 pulls the second swing plate 803 away from the wall, so that the nozzle 3 always maintains the spraying process of reciprocating up and down. The second gear 8041 on the first rotating rod 804 is meshed with the inner gear ring 132 of the gear ring 13 when rotating, and the gear ring 13 rotates and meshes with the third gear 141 through the outer gear ring 133. The third rotating rod 14 connected to the third gear 141 drives the second rotating rod 805 to rotate through the third synchronous wheel 15 and the third synchronous belt. The second rotating rod 805 drives the nozzle 3 to rotate in the opposite direction to the second swing plate 803, thereby ensuring that the nozzle 3 is always facing the wall during the painting operation, and then on the basis of not changing the output power of the paint spraying, the same spray angle of the paint spray to the wall is ensured, so that the paint is evenly sprayed on the wall, ensuring the painting effect;

[0058] As the lifting part 2 works, after the sleeve 204 moves to the upper side of the screw 203, the second motor 6 is controlled to operate, and the output shaft of the second motor 6 drives the rotating seat 602 to rotate through the rotating rod 601, and the rotating seat 602 drives the straight tube 502 to rotate, so that the straight tube 502 drives the nozzle 3 connected to its end to lift up, so that the height of the subsequent nozzle 3 is not lower than the height of the screw 203, which is convenient for the nozzle 3 to spray paint on the upper side of the wall; when the rotating seat 602 rotates, the arc-shaped rack frame 6021 on the bottom side of the rotating seat 602 and the first gear 70 on the first winding rod 701 are rotated. 11 meshing transmission, the first winding rod 701 winds up the first pull rope 702, and the first pull rope 702 applies tension to the fixed plate 5021, so that the straight tube 502 moves horizontally in the rotating seat 602, so that the straight tube 502 moves closer to the wall, making up for the distance loss of the nozzle 3 connected to the end of the straight tube 502 away from the wall due to the flipping of the straight tube 502, so that the nozzle 3 always maintains the same distance from the wall during the up and down reciprocating painting process, and then on the basis of not changing the output power of the painting, the same spray force of the paint to the wall is ensured, so that the paint is evenly sprayed on the wall, ensuring the painting effect;

[0059] When the second motor 6 drives the straight tube 502 to rotate clockwise through the rotating seat 602, so that the end of the straight tube 502 close to the wall is lifted up, the main gear 6011 on the rotating rod 601 is meshed with the sub-gear 901 on the transmission rod 9, so that the sub-gear 901 drives the transmission rod 9 to rotate counterclockwise, and the transmission rod 9 drives the rotating shaft 801 to rotate counterclockwise through the first synchronous wheel 10 and the first synchronous belt, so that the second adjustment component drives the spray head 3 to rotate downward, so as to ensure that the spray head 3 always maintains the same angle with the wall during the up and down reciprocating painting process, and then ensures that the spray angle of the paint to the wall is the same without changing the output power of the paint, so that the paint is evenly sprayed on the wall, ensuring the painting effect;

[0060] After finishing spraying the paint on a wall from bottom to top, the base 1 is moved to drive the nozzle 3 to move to the side wall, so that the nozzle 3 sprays paint on another part of the wall from top to bottom, and the up and down reciprocating action of the nozzle 3 is repeated in sequence to realize the spraying of the whole wall.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
