Description

Technical Field

[0001] The invention relates to the technical field of interior decoration, in particular to an indoor wall painting device. Background Art

[0002] In the prior art, indoor wall painting devices generally require a person to stand on a scaffold, bend down to dip in paint, and then manually brush the paint on the wall. After dipping in the paint, due to the fluidity of the paint, the paint will flow to the ground or splash onto the clothes of the painter before being applied to the wall, causing pollution and waste of materials. At the same time, manual painting uses a scaffold. When it is necessary to paint a high part of the wall, the person needs to climb up the scaffold, and when it is necessary to paint a low part of the wall, the person needs to jump down from the scaffold, which is time-consuming and laborious. Summary of the invention

[0003] The invention provides an indoor wall painting device to solve the technical problems of time-consuming and labor-intensive manual use of scaffolding and material waste in the painting process.

[0004] The present invention is achieved by the following measures:

[0010] Furthermore, the belt transmission assembly includes a pulley A, which is sleeved on the bottom of the screw, a support plate is provided on the outside of the support column, a motor is provided on the support plate, a pulley B is provided on the output shaft of the motor, and a synchronous belt is provided on the pulley B and the pulley A, and the synchronous belt passes through the notch.

[0011] Furthermore, the rotating mechanism includes a gear A, a pin is provided on the slider, the gear A is provided on the pin, a rotating shaft is provided on one side of the pin, the rotating shaft passes through the slider, a motor B is provided on the rotating shaft provided at the bottom of the slider, a gear B is provided on the rotating shaft provided at the top of the slider, the gear B is meshed with the gear A, a connecting pipe is provided at the upper end of the gear A, a ring is provided on the connecting pipe, the connecting pipe and the ring are sleeved on the pin, and the swing mechanism is provided at the upper end of the ring.

[0012] Furthermore, the swing mechanism includes a substrate, which is arranged on the ring, a base is arranged on the substrate, an electric push rod A is arranged on the base, a rotating shaft is arranged between the push rod seat of the electric push rod A and the base, and the paint brushing mechanism is arranged on the piston rod of the electric push rod A.

[0013] Furthermore, the paint brushing mechanism includes a support rod, which includes a connecting portion and a supporting portion. A brush body is pivotally arranged on the supporting portion. The connecting portion is fixedly connected to the piston rod of the electric push rod A. The supporting portion is horizontally arranged, and the connecting portion is inclined.

[0014] Beneficial effects of the present invention:

[0015] 1. The brush body of the present invention automatically dips into the paint, and there is no need to manually go up and down the scaffolding frequently, which saves time and labor. After dipping into the paint, the dripping paint can fall back into the paint box. At the same time, the swing mechanism tilts out of the support frame, and the wall can be painted up and down, saving the cost of manual operation.

[0016] 2. The alignment mechanism can ensure that the bracket is in a vertical state and position the bracket to prevent the bracket from moving left and right or tilting during the wall painting process. The lifting mechanism can paint the wall up and down, and can ensure that the paint dipped by the paint brushing mechanism falls back into the paint box. The rotating mechanism can ensure that the swing mechanism tilts out of the bracket to facilitate painting the wall surface. One function of the swing mechanism is to ensure that the paint brushing mechanism dips into the paint when moving downward, and the other function is to rotate with the rotation of the rotating mechanism, thereby ensuring that the paint brushing mechanism protrudes out of the bracket, and the paint brushing mechanism directly paints the wall.

[0017] 3. The support column plays a supporting role and can ensure the vertical direction of painting. The groove has a guiding and limiting function. The lifting mechanism can ensure that the brush body is moved from the top to the bottom of the wall. The alignment mechanism can ensure that the support column is stably fixed on the ground.

[0018] 4. When you need to paint a certain part of the wall, align the suction cup with the wall and push the support column toward the wall. The suction cup of the support column squeezes the wall and squeezes the air out of the suction cup. Under the action of atmospheric pressure, the suction cup is fixed to the wall.

[0019] 5. The screw drive assembly ensures the lifting of the brush body, the belt drive assembly provides power for the screw drive assembly, the notch prevents the belt drive assembly from interfering with the support column, ensures the normal operation of the belt drive assembly, and the mounting hole provides an installation position for the screw in the screw drive assembly.

[0020] 6. The purpose of setting the lead screw in the groove is to prevent the paint from dripping onto the lead screw and into the external thread of the lead screw, causing the slider to be unable to move up and down normally. The purpose of setting the belt drive assembly at the bottom of the support column is to reduce the pressure on the upper end of the support column.

[0021] 7. Because the slider is set on the screw, and the screw is set in the groove of the support column, a part of the slider is also set in the groove. Under the limit of the groove, the slider will move up and down with the rotation of the screw, and then paint the upper and lower surfaces of the wall.

[0022] 8. The purpose of setting the rotating mechanism is to ensure the angle setting between the swing mechanism and the supporting column, that is, the swing mechanism must protrude from the supporting column so that the swing mechanism can paint the wall.

[0023] 9. The rotation of the collar drives the base plate to rotate, the rotation of the base plate drives the electric push rod to rotate, the rotation of the electric push rod drives the paint brushing mechanism to rotate, thereby ensuring that the paint brushing mechanism and the support column are tilted to facilitate the paint brushing mechanism to contact the wall.

DETAILED DESCRIPTION

[0036] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0037] A device for painting indoor walls comprises a bracket 1. An alignment mechanism 2 is arranged at the front end of the bracket 1. The alignment mechanism can ensure that the bracket is in a vertical state and position the bracket to prevent the bracket from moving left and right or tilting during the wall painting process. Lifting mechanisms 3 are symmetrically arranged on both sides of the bracket 1. The lifting mechanisms can paint the wall up and down and can ensure that the paint dipped by the paint brushing mechanism falls back into a paint box. A rotating mechanism 4 is arranged on the lifting mechanism 3. The rotating mechanism can ensure that the swing mechanism tilts out of the bracket to facilitate painting the wall surface. A swing mechanism 5 is arranged on the rotating mechanism 4. One function is to ensure that the paint brushing mechanism dips in paint when moving downward, and the other function is to rotate with the rotation of the rotating mechanism, thereby ensuring that the paint brushing mechanism protrudes out of the bracket. A paint brushing mechanism 7 is arranged at the end of the swing mechanism 5. The paint brushing mechanism directly paints the wall surface. A paint box 8 is arranged at the bottom of the bracket 1, and paint is arranged in the paint box 8.

[0038] The bracket 1 includes two symmetrically arranged support columns 11, which play a supporting role and can ensure the vertical direction of painting. A groove 12 is arranged on each support column 11, which has the function of guiding and limiting. A lifting mechanism 3 is arranged in the groove 12, which can ensure that the brush body is moved from the top to the bottom of the wall. A paint box 8 is arranged between the two support columns 11, and the paint box is used to hold the paint. The paint box 8 is arranged at the bottom of the two support columns 11, and an alignment mechanism 2 is arranged on the front side of the paint box 8. The alignment mechanism can ensure that the support column is stably fixed on the ground.

[0039] The alignment mechanism 2 comprises a push rod 21 , one end of which is fixedly connected to the paint box 8 , and the other end of which is provided with a suction cup 22 .

[0040] When a certain part of the wall facade needs to be painted, align the suction cup with the wall, push the support column toward the wall, and the support column suction cup presses the wall, squeezing the air out of the suction cup. Under the action of atmospheric pressure, the suction cup is fixed to the wall.

[0041] The lifting mechanism 3 includes a screw drive assembly 31 and a belt drive assembly 32. The screw drive assembly ensures the lifting of the brush body, and the belt drive assembly provides power for the screw drive assembly. A notch 111 is provided at the bottom of each support column 11, and a belt drive assembly 32 is provided at the notch 111. The notch prevents the belt drive assembly from interfering with the support column to ensure the normal operation of the belt drive assembly. The groove 12 is provided with mounting holes at both ends, and the screw drive assembly 31 is provided in the mounting holes. The mounting holes provide a mounting position for the screw in the screw drive assembly.

[0042] The lead screw drive assembly 31 includes a lead screw 311, and the upper and lower ends of the lead screw 311 are respectively arranged in the groove 12. The purpose of setting the lead screw in the groove is to prevent the paint from dripping on the lead screw. The paint drips into the external thread of the lead screw, causing the slider to be unable to move up and down normally. The lead screw 311 is provided with a slider 312, and the slider is provided with an internal thread corresponding to the external thread of the lead screw. The slider 312 is provided with a rotating mechanism 4, and the bottom of the lead screw 311 is provided with a belt drive assembly 32, and the belt drive assembly 32 is arranged at the bottom of the support column. The belt drive assembly is arranged at the bottom of the support column to reduce the pressure on the upper end of the support column.

[0043] The belt drive assembly 32 includes a pulley A321, which is sleeved on the bottom of the screw 311. A support plate 112 is provided on the outer side of the support column 11, and a motor 322 is provided on the support plate 112. A pulley B323 is provided on the output shaft of the motor 322. A synchronous belt 324 is provided on the pulley B323 and the pulley A321, and the synchronous belt 324 passes through the notch 111.

[0044] Start the motor, the motor output shaft rotates to drive pulley B to rotate, and the rotation of pulley B drives pulley A to rotate through the synchronous belt. Pulley A is set at the bottom of the screw, so the screw rotates with the rotation of pulley A.

[0045] Because the slider is arranged on the lead screw, and the lead screw is arranged in the groove of the support column, a part of the slider is also arranged in the groove. Under the limitation of the groove, the slider will move up and down with the rotation of the lead screw, and then paint the upper and lower surfaces of the wall.

[0046] The rotating mechanism 4 includes a gear A41, a pin is provided on the slider 312, the gear A41 is provided on the pin, a rotating shaft 42 is provided on one side of the pin, the rotating shaft 42 passes through the slider 312, a motor B43 is provided on the rotating shaft provided at the bottom of the slider 312, a gear B44 is provided on the rotating shaft provided at the top of the slider 312, the gear B44 is meshed with the gear A41, a connecting tube 411 is provided at the upper end of the gear A41, a ring 412 is provided on the connecting tube, the connecting tube and the ring 412 are sleeved on the pin, and a swing mechanism 5 is provided at the upper end of the ring 412.

[0047] Start motor B, the output shaft of motor B rotates to drive the shaft to rotate. Because gear B is set on the shaft, the rotation of the shaft drives gear B to rotate. Because gear B and gear A are meshed, the rotation of gear B drives gear A to rotate. The rotation of gear A drives the ring to rotate through the connecting pipe, and then drives the swing mechanism to rotate.

[0048] The purpose of setting the rotating mechanism is to ensure the angle setting between the swing mechanism and the supporting column, that is, the swing mechanism should protrude from the supporting column, so that the swing mechanism can paint the wall.

[0049] The swing mechanism 5 includes a base plate 51, which is arranged on the collar 412. A base 511 is arranged on the base plate 51, an electric push rod A52 is arranged on the base 511, a rotating shaft 53 is arranged between the push rod seat of the electric push rod A52 and the base 511, and a paint brushing mechanism 7 is arranged on the piston rod of the electric push rod A52.

[0050] The rotation of the collar drives the base plate to rotate, the rotation of the base plate drives the electric push rod to rotate, the rotation of the electric push rod further drives the paint brushing mechanism to rotate, thereby ensuring that the paint brushing mechanism and the support column are tilted to facilitate the paint brushing mechanism to contact the wall.

[0051] The paint brushing mechanism 7 includes a support rod 71, and the support rod 71 includes a connecting portion 711 and a supporting portion 712. A brush body 72 is arranged on the supporting portion 712. The connecting portion is fixedly connected to the piston rod of the electric push rod A. The supporting portion is arranged horizontally, and the connecting portion is arranged inclined.

[0052] The working process of the present invention is explained with the brush body in the paint box as the starting position. The working process of the present invention includes the following steps:

[0053] Step 1: After the brush body is immersed in the paint box and enough paint is applied, the motor in the belt drive assembly is started. The motor output shaft rotates to drive the pulley B to rotate. The pulley B rotates to drive the pulley A to rotate through the synchronous belt. The pulley A is set at the bottom of the screw, so the screw rotates with the rotation of the pulley A. Because the slider is set on the screw and the screw is set in the groove of the support column, a part of the slider is also set in the groove. Under the limit of the groove, the slider will move up and down with the rotation of the screw. At this time, it is assumed to be an upward motion;

[0054] Step 2: When the slider rises to the upper part of the paint box and the brush body leaves the paint, turn off the motor and ensure that the brush body is stationary for a while until the paint stops dripping from the brush body. The dripping paint is directly recovered into the paint box;

[0055] Step 3: Start the motor again, and the slider continues to rise along the axis of the screw. When it rises to a certain distance, turn off the motor;

[0056] Step 4: Start motor B. The output shaft of motor B rotates to drive the shaft to rotate. Since gear B is provided on the shaft, the rotation of the shaft drives gear B to rotate. Since gear B is meshed with gear A, the rotation of gear B drives gear A to rotate. The rotation of gear A drives the ring to rotate through the connecting pipe, and then drives the swing mechanism to rotate.

[0057] Step 5: When the swing mechanism rotates and extends out of the support column, the brush body extends out of the support column along with the swing mechanism. When the brush body touches the wall, the motor in the belt drive assembly is started in reverse to ensure that the slider moves downward, thereby driving the brush body to paint the wall from top to bottom.

[0058] Technical features not described in the present invention can be achieved through or by adopting existing technologies and will not be described in detail here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
