TECHNICAL FIELD

[0001] The present application relates to the field of roofing construction tools, in particular to a roofing painting construction device. BACKGROUND

[0002] When decorating a house, paint is applied to achieve the effects of beauty, corrosion resistance, salt and alkali resistance, and water resistance. When painting a wall, painting equipment is used. The existing painting equipment usually has a support connected to a paint roller, which contacts the painted object during rotation to apply paint to the surface of the painted object. The work efficiency is low because the paint needs to be applied once and rolled once. SUMMARY

[0003] The purpose of the present application is to provide a roofing painting construction device to improve work efficiency.

[0004] The purpose of the present application is achieved by the following technical solutions:

[0005] A roofing painting construction device includes a tubular cavity with an opening on one side, two side plates fixed at both ends of the tubular cavity, a central shaft and two support rollers rotating between the two side plates, a central roller fixed on the central shaft coaxially located in the tubular cavity, two support rollers located on the opening side and symmetrically arranged above and below the opening, a painting belt sleeved on the central roller and the two support rollers and passing through the opening, a feeding pipe provided below the opening away from the tubular cavity, a box for containing paint, a supply pump provided on one side of the lower end of the box, and a hose connecting the supply pump and the feeding pipe to supply paint to the tubular cavity.

[0006] The tubular cavity has auxiliary rollers rotating horizontally on both sides of the opening to guide the painting belt and prevent the painting belt from contacting the edges of the upper and lower ends of the opening.

[0007] The central roller has rotating plates at both ends, an arc-shaped baffle fixed between the two rotating plates, and a floating column provided away from the opening.

[0008] The central shaft has C-shaped plates rotating through the two side plates at both ends, and a control rod fixed at the center of the C-shaped plate.

[0009] The tubular cavity has a connecting frame fixed outside the opening side, and a tension spring installed between the connecting frame and the C-shaped plate.

[0010] The control rod has an extension sleeve sleeved and sliding thereon.

[0011] The control rod is provided with a blind hole, a sliding block is matched and slides in the blind hole, a spring is arranged between the sliding block and the bottom of the blind hole, a lock column is arranged at the end of the sliding block away from the spring, a thin column is coaxially arranged at the other end of the lock column, a pressing plate is arranged at the other end of the thin column, and an elongated hole is axially arranged on the extension sleeve.

[0012] Universal wheels are arranged at the lower end of the box body.

[0013] The stirring frame is arranged at the inside of the box body away from the supply pump.

[0014] A plurality of horizontal rods are fixed to the inside of the box body above the stirring frame, a push support frame is fixed to the side of the box body away from the supply pump, a bag opening frame is fixed to the push support frame and is used for limiting the control rod.

[0015] The beneficial effects of the present application are as follows:

[0016] 1. The paint is continuously supplied into the pipe cavity by the supply pump and contacts the painting belt located in the pipe cavity, when the painting belt rolls on the wall surface, the painting belt with paint will move to the outside of the pipe cavity and contact the wall surface, and the painting is completed, thereby improving the work efficiency and eliminating the need for rolling once after painting once.

[0017] 2. The painting belt between the two supporting rollers contacts the wall surface to be painted, instead of the original paint roller line contact, so that the paint can be more closely attached to the wall surface and the adhesion of the paint to the wall surface is improved.

[0018] 3. The buoyancy of the floating column in the paint in the pipe cavity, when the paint in the pipe cavity increases, the floating column will drive the arc-shaped baffle to adhere to the inner wall of the pipe cavity through the two rotating plates and rotate upward, thereby plugging the port of the feeding pipe and controlling the amount of paint in the pipe cavity, avoiding the overflow of the paint in the pipe cavity from the opening and causing waste; at the same time, the control of the liquid level height of the paint in the pipe cavity is formed, the painting belt uniformly dips the paint, and the uniformity of the painting thickness is improved.

[0037] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0038] As shown in the figure, the roof paint construction device is described in detail: Figures 1-10

[0039] ​The utility model provides a kind of roof painting construction device, including one side with opening 202 pipe cavity 201, both ends of pipe cavity 201 are fixed with side plate 203, a central shaft 301 and two support rollers 305 are rotated between two side plates 203, central roller 302 is fixed on central shaft 301 and coaxially located in pipe cavity 201, two support rollers 305 are located at opening 202 side and symmetrically arranged about opening 202 up and down, central roller 302 and two support rollers 305 are set with painting belt 304 passing through opening 202, the lower side of pipe cavity 201 away from opening 202 is equipped with feed pipe 204, it also includes the box 101 for containing paint, the inside lower end of box 101 is equipped with supply pump 102 on one side, supply pump 102 is communicated with feed pipe 204 by hose, for supplying paint to pipe cavity 201.

[0040] A cylindrical inner cavity is formed by pipe cavity 201 and two side plates 203 for containing paint, wherein central roller 302 rotates in the cylindrical inner cavity through central shaft 301, and forms support for painting belt 304 together with two support rollers 305, facilitating the rotation of painting belt 304 through central roller 302 and two support rollers 305; painting belt 304 between two support rollers 305 is vertically arranged and used to contact the wall surface, opening 202 on pipe cavity 201 is directly opposite painting belt 304 between two support rollers 305, when painting belt 304 between two support rollers 305 is attached to the wall surface, pipe cavity 201 below opening 202 can contain a certain amount of paint, which can immerse painting belt 304 below central roller 302 while ensuring that the paint does not overflow from opening 202, causing waste, and form the dipping of painting belt 304 moving to this place on the paint;

[0041] In use, first, add paint to box 101, then start supply pump 102, which supplies paint in box 101 to pipe cavity 201 through hose and feed pipe 204, so that painting belt 304 in pipe cavity 201 contacts the paint; then, attach painting belt 304 between two support rollers 305 to the wall surface to be painted, and push pipe cavity 201 to move along the direction of painting belt 304, through the friction between painting belt 304 and the wall surface, when pipe cavity 201 moves relative to the wall surface, the contact between painting belt 304 and the wall surface is relatively stationary, then forming the rolling of painting belt 304 on the wall surface, so that, as painting belt 304 rolls, painting belt 304 in pipe cavity 201 contacting the paint will move to between two support rollers 305, so that the paint adheres to the wall surface, completing the painting of the wall surface; since the paint in pipe cavity 201 is supplied by supply pump 102, it ensures that painting belt 304 in pipe cavity 201 is always in contact with the paint, so that it is not necessary to dip the paint and roll it as in the use of existing devices, greatly improving work efficiency;

[0042] Moreover, the "surface contact" formed by the contact between the painting belt 304 and the wall between the two supporting rollers 305 can make the paint adhere to the wall more closely compared with the "line contact" between the original paint roller and the wall, thereby improving the adhesion between the paint and the wall; moreover, since the painting belt 304 rolls with the wall, it can ensure that each part of the painting belt 304 is in contact with the wall after being dipped in the paint, which can ensure the uniformity of the painting thickness compared with the paint roller which carries less and less paint when rolling on the wall.

[0043] The painting belt 304 can be made of nylon cloth with mixed wool or sponge uniformly attached to the outer surface.

[0044] Further,

[0045] The auxiliary rollers 303 are horizontally rotatable on the upper and lower sides of the opening 202 inside the tube body 201 to guide the painting belt 304 and avoid the contact between the painting belt 304 and the upper and lower edges of the opening 202.

[0046] The two ends of the two auxiliary rollers 303 are rotatably connected to the two side plates 203, so that when the painting belt 304 rolls on the wall, it can form rolling contact with the auxiliary rollers 303, instead of scraping contact between the outer side of the painting belt 304 and the upper and lower edges of the opening 202, thereby avoiding affecting the carrying of the paint by the painting belt 304.

[0047] Further,

[0048] The two ends of the central roller 302 are rotatably connected to the rotating plates 401, and the arc-shaped baffle 402 is fixed between the two rotating plates 401, slides with the inner wall of the tube body 201 and is provided with a floating column 403 away from the opening 202.

[0049] When not in use, the paint strip 304 between the two supporting rollers 305 is vertically arranged, and the opening 202 is horizontally arranged, the weight of the arc-shaped baffle 402 itself will drive the two rotating plates 401 to rotate at both ends of the central roller 302, so that the arc-shaped baffle 402 is located at the lowermost part of the pipe cavity 201. When the paint supply pump 102 supplies paint into the pipe cavity 201, the floating column 403 will be affected by the buoyancy generated by the paint, and will drive the arc-shaped baffle 402 to rotate upward and away from the opening 202 by adhering to the inner wall of the pipe cavity 201 through the two rotating plates 401, so as to block the port of the paint supply pipe 204 through the arc-shaped baffle 402, so that the paint cannot enter the pipe cavity 201 again. As the painting work proceeds, the paint gradually decreases, the arc-shaped baffle 402 descends, the port of the paint supply pipe 204 is opened again, and the paint will form a supply again, thereby controlling the amount of paint in the pipe cavity 201, avoiding waste caused by overflow of the paint from the opening 202; at the same time, the control of the liquid level of the paint in the pipe cavity 201 is formed, thereby controlling the painting of the paint strip 304 dipped into the pipe cavity 201, ensuring the uniformity of the paint dipped by each section of the paint strip 304, and further improving the uniformity of the painting thickness.

[0050] Further:

[0051] The C-shaped plate 501 is rotatably arranged at both ends of the central shaft 301 penetrating the two side plates 203, and the control rod 503 is fixed at the center of the C-shaped plate 501.

[0052] Since the paint strip 304 between the two supporting rollers 305 is vertically contacted with the wall, the operator can push the pipe cavity 201 to move up and down for painting by holding the control rod 503 during painting, and the use of the control rod 503 increases the painting range, and when the pipe cavity 201 moves up and down, the control rod 503 can rotate with the central shaft 301 through the C-shaped plate 501, so as to adjust the included angle between the control rod 503 and the wall to adapt to a large range of work.

[0053] Further:

[0054] The connecting frame 205 is fixed outside the pipe cavity 201 away from the opening 202, and the tension spring 502 is installed between the connecting frame 205 and the C-shaped plate 501.

[0055] By setting the tension of the tension spring 502, the control rod 503 and the paint strip 304 between the two supporting rollers 305 can be kept in a vertical state when the user holds the control rod 503 and the paint strip 304 is separated from the wall, so as to avoid that when the paint strip 304 is separated from the wall during painting, the pipe cavity 201 automatically falls downward in the C-shaped plate 501, causing the remaining paint in the pipe cavity 201 to spill from the opening 202, thereby improving the practicality of use.

[0056] Further:

[0057] The control rod 503 is sleeved with an extension sleeve 701.

[0058] The control rod 503 is provided with a blind hole 504, and a sliding block 601 is matched and slides in the blind hole 504. A spring 602 is arranged between the sliding block 601 and the bottom of the blind hole 504. A lock column 603 is arranged at the end of the sliding block 601 away from the spring 602. A thin column 604 is coaxially arranged at the other end of the lock column 603. A pressing plate 605 is arranged at the other end of the thin column 604. An elongated hole 702 is axially arranged on the extension sleeve 701. A plurality of lock holes 703 are arranged on the elongated hole 702. The diameters of the lock holes 703 correspond to the diameter of the lock column 603. The width of the elongated hole 702 corresponds to the diameter of the thin column 604.

[0059] By sliding the extension sleeve 701 on the control rod 503, the total length of the two can be adjusted, which is more convenient for use and further increases the working range.

[0060] When it is necessary to adjust the sliding of the extension sleeve 701 on the control rod 503, the pressing plate 605 is pressed to make the pressing plate 605 push the lock column 603 to slide into the blind hole 504 and press the spring 602, so that the lock column 603 slides out of the lock hole 703, and then the thin column 604 slides into the elongated hole 702. At this time, the extension sleeve 701 can be axially slid. After adjusting to the appropriate length, the pressing plate 605 is released, and the elastic force of the spring 602 will push the lock column 603 to slide outward and insert into the corresponding lock hole 703 on the elongated hole 702, so as to lock the extension sleeve 701 and the control rod 503 again, avoiding the relative sliding of the extension sleeve 701 and the control rod 503, which affects the work.

[0061] The diameter of the lock hole 703 is greater than the width of the elongated hole 702, and the center of the lock hole 703 is located on the center line of the elongated hole 702, so that after the lock column 603 slides into the lock hole 703, the extension sleeve 701 is limited.

[0062] Further:

[0063] The universal wheels are arranged at the four corners of the lower end of the box body 101, which facilitates the movement of the box body 101 and cooperates with the painting work.

[0064] Further:

[0065] The box body 101 is internally rotatably provided with a stirring frame 103 away from the supply pump 102.

[0066] The first motor installed below the box body 101 drives the stirring frame 103 to stir the paint, so that the paint is always in a uniform state and is conveniently supplied by the supply pump 102.

[0067] Further:

[0068] A plurality of cross bars 104 are fixed above the stirring frame 103 and inside the box body 101 . A pushing frame 105 is fixed to the side of the box body 101 away from the supply pump 102 . A bag opening frame 106 is fixed on the pushing frame 105 for limiting the control rod 503 .

[0069] After the device is used, when it is folded up, the painting belt 304 between the two support rollers 305 can be placed on the multiple cross bars 104, and the vertical control rod 503 can be pushed toward the pushing frame 105 and inserted into the bag opening frame 106 to prevent the control rod 503 from shaking;

[0070] Among them, multiple cross bars 104 form support for the painting belt 304 while forming protection for the stirring frame 103 to prevent damage to the stirring frame 103; the opening frame 106 is a U-shaped structure, and both sides of the inner wall of the opening are provided with ridges. When the control rod 503 is pushed into the U-shaped structure, the two sides of the U-shaped structure are deformed to make the control rod 503 slide over the ridges, and the ridges form a limit to prevent the control rod 503 from shaking, which is convenient for transportation or storage.

[0071] Of course, the above description is not a limitation of the instructions for use, 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 also fall within the scope of protection of the present invention.
