Description

TECHNICAL FIELD

[0001] The present application relates to the field of wall decoration, in particular to a wall decoration construction device and a construction method thereof. BACKGROUND

[0002] In the process of house building and decoration, the wall surface needs to be painted with paint. The existing brushing work is generally manually operated, and in order to provide brushing efficiency, a brushing device is also used for mechanical construction. For example, a wall automatic painting device is disclosed in Chinese Patent No. 202111299214X.

[0003] Therefore, the existing brushing device mainly includes a displacement control mechanism (corresponding to the lifting linear module and the brush horizontal movement mechanism mentioned above) and a brushing tool (corresponding to the brush mentioned above). The displacement control mechanism is used to drive the brush to move up and down and horizontally relative to the wall surface to complete the brushing of the wall surface.

[0004] However, before brushing, the brush needs to be dipped with paint. Although multiple brushes can be used alternately to brush in turn, the paint on a single brush is continuously transferred to the wall surface during use. In the case that the paint is used up, the paint that can be transferred by the brush also gradually decreases, resulting in uneven brushing amount during the use of a single brush, which easily leads to a decrease in the brushing effect of the wall surface.

[0050] The flow uniformizing box 5 is located between the transfer cylinder 4 and the transfer sponge block 3. The flow uniformizing box 5 is in an elongated strip shape, is parallel to the brush roller 2, and is horizontally slidably connected to a horizontal guide rail 11 arranged on one side of the paint tank 1. The first reciprocating structure 6 can be a pneumatic cylinder or an electric cylinder. The first reciprocating structure 6 is used to drive the flow uniformizing box 5 to reciprocate along the length direction of the flow uniformizing box 5.

[0051] Two discharge parts 41 are communicated with the equalizing box 5 respectively, and the discharge hose 13 is provided with a second switch valve 15, which can be an electromagnetic valve to open and close the discharge hose 13; the bottom surface of the equalizing box 5 is attached to the upper surface of the transferred sponge block 3, and the abutting and attaching surface of the transferred sponge block 3 and the equalizing box 5 is provided as a curved surface, and the middle part of the curved surface is in an upward arch shape.

[0053] As shown in Figure 5 , the two side edges of the discharge hole 51 along the length direction of the equalizing box 5 are provided with guide pieces 52, the guide piece 52 is a rubber piece, the guide piece 52 is inclined upward and towards the middle part of the discharge hole 51, and the part of the guide piece 52 connected with the side edge of the discharge hole 51 is provided with a deformation avoiding groove 53.

[0054] Embodiment 1 also discloses a construction method of the wall decoration construction device, comprising the following steps:

[0055] First, clean the wall, specifically, use a brush or cloth to wipe off the dust on the wall, then arrange the wall decoration construction device, and then perform brushing.

[0056] First, the paint in the paint box 1 enters the first chamber 401 and the second chamber 402 through the feeding hose 12, so that the first chamber 401 and the second chamber 402 are filled with paint, by closing the first switch valve 14 corresponding to the first chamber 401 and opening the second switch valve 15 corresponding to the first chamber 401, opening the first switch valve 14 corresponding to the second chamber 402 and closing the second switch valve 15 corresponding to the second chamber 402, so that the discharge hose 13 corresponding to the first chamber 401 is connected, the feeding hose 12 corresponding to the first chamber 401 is disconnected, the feeding hose 12 corresponding to the second chamber 402 is connected, and the discharge hose 13 corresponding to the second chamber 402 is disconnected.

[0057] Then, the first servo motor 43 rotates forward to drive the extrusion block 42 to rotate forward and move axially along the middle transfer cylinder 4 to compress the volume of the first chamber 401, so as to press the paint in the first chamber 401 into the flow equalization box 5 through the discharge hose 13, and the extrusion block 42 drives the spiral blade 45 to rotate to stir the paint, and under the pressure of the extrusion block 42, the paint in the flow equalization box 5 flows to the transfer sponge block 3 through the discharge hole 51. During the forward rotation of the extrusion block 42, the volume of the second chamber 402 increases, and the paint is continuously supplemented into the second chamber 402 through the corresponding feed hose 12 to ensure that the paint in the second chamber 402 is in a full state.

[0058] When the extrusion block 42 moves axially to the end of the stroke in the first chamber 401 (one side of the spiral blade 45 abuts against the inner tapered surface of the discharge part 41), the second switch valve 15 corresponding to the second chamber 402 is opened, the first switch valve 14 corresponding to the second chamber 402 is closed, the second switch valve 15 corresponding to the first chamber 401 is closed, and the first switch valve 14 corresponding to the first chamber 401 is opened, so that the discharge hose 13 corresponding to the first chamber 401 is disconnected, the feed hose 12 corresponding to the first chamber 401 is connected, the feed hose 12 corresponding to the second chamber 402 is disconnected, and the discharge hose 13 corresponding to the second chamber 402 is connected.

[0059] The first servo motor 43 reversely rotates to drive the extrusion block 42 to reversely rotate and move axially along the middle transfer cylinder 4 to compress the volume of the second chamber 402, so as to press the paint in the second chamber 402 into the flow equalization box 5 through the discharge hose 13, and the paint in the flow equalization box 5 flows to the transfer sponge block 3 through the discharge hole 51. During the reverse rotation of the extrusion block 42, the volume of the first chamber 401 increases, and the paint is continuously supplemented into the first chamber 401 through the corresponding feed hose 12 to ensure that the paint in the first chamber 401 is in a full state, so as to realize continuous and uniform feeding of the transfer sponge block 3,

[0060] Then, the displacement control mechanism 10 is started to drive the brush roller 2 to roll on the wall, and the brush roller 2 rotates to continuously take away the paint absorbed by the transfer sponge block 3 and uniformly roll on the wall.

[0061] During the rotation of the brush roller 2, the first reciprocating structure 6 drives the flow equalization box 5 to continuously reciprocate, and the guide piece 52 on the flow equalization box 5 moves horizontally relative to the paint in the flow equalization box 5. The force will force the paint to enter the discharge hole 51 along the inclined surface of the guide piece 52, so as to accelerate the rate and intensity of the paint discharged into the transfer sponge block 3, thereby improving the paint absorption effect of the transfer sponge block 3.

[0062] After the wall is coated with the roller and dried, the wall is patched with putty according to the situation, and then polished with sandpaper, cleaned, and then coated with the roller and patched with putty for 2-3 times to complete the finishing construction of the wall.

[0063] The implementation principle of the embodiment 1 is that the uniform feeding assembly can continuously supplement the paint to the brush roller 2 during the movement of the brush roller 2 to ensure the uniformity of the roller coating; secondly, the uniform force extrusion of the paint in the transfer cylinder 4 can be realized by the forward and reverse movement of the extrusion block 42, and the uniform force extrusion can realize the uniform feeding of the paint to the transfer sponge block 3 and the brush roller 2 under the balanced extrusion force, that is, the uniform feeding is realized to ensure the uniformity of the brush coating.

[0064] Moreover, the paint in the transfer cylinder 4 can be stirred by the spiral piece 45 to reduce the deposition of the paint to ensure the uniformity of the paint itself and further improve the uniformity of the brush coating.

[0065] Embodiment 2

[0066] The difference between the embodiment 2 and the embodiment 1 is that, as shown in Figure 6 the multiple installation ropes 55 are connected between the two side edges of the material outlet hole 51 along the width direction of the flow uniformizing box 5, the installation ropes 55 are provided with multiple balls 54, the balls 54 are provided with multiple through holes (not shown in the figure), or the balls 54 are hollow spherical, and the lower part of the ball 54 abuts against the upper surface of the transfer sponge block 3.

[0067] In this way, the mesh structure composed of the installation ropes 55 and the balls 54 can reduce the situation that the part of the structure of the transfer sponge block 3 is clamped into the material outlet hole 51 to reduce the friction force when the flow uniformizing box 5 moves relative to the transfer sponge block 3.

[0068] Secondly, the ball 54 is sunk into the upper surface of the transfer sponge block 3, the paint can be soaked into the transfer sponge block 3 through the through holes of the ball 54 and the gap between the balls 54, thereby greatly improving the paint absorption effect of the transfer sponge block 3.

[0069] Embodiment 3

[0070] The difference between the embodiment 3 and the embodiment 1 is that, as shown in Figure 7 the limiting spring 46 is fixedly connected between the extrusion block 42 and the spiral piece 45, the limiting spring 46 is arranged along the axial direction of the rotating rod 44, and the elastic force of the limiting spring 46 forces the outer conical surface of the spiral piece 45 to abut against the inner conical surface of the material outlet part 41, that is, the spiral piece 45 and the material outlet part 41 are kept in the matching state.

[0071] In this way, the extrusion block 42 can transmit torque to the spiral blade 45 to drive the spiral blade 45 to rotate and stir the paint, and can also enable the spiral blade 45 to generate a conveying force on the paint to ensure that the paint can quickly pass through the discharge hose 13 to the transfer sponge block 3, thereby reducing the accumulation of paint in the transfer cylinder 4.

[0072] Embodiment 4

[0073] Embodiment 4 differs from embodiment 1 in that, as shown in Figure 8 the flow equalization box 5 is in the form of a ring sleeve, the flow equalization box 5 is sleeved on the outside of the transfer cylinder 4, the horizontal guide rail 11 is in sliding connection with the inner wall of the flow equalization box 5, and the discharge holes 51 are uniformly distributed on the outer peripheral surface (not shown in the figure) of the flow equalization box 5.

The paint tank 1 is fixed with a circular-arc-shaped retainer 16 on one side, and the retainer 16 is used to cover part of the outer peripheral surface of the transfer sponge block 3 to keep the position of the transfer sponge block 3 stable.

[0075] The two end surfaces of the transfer sponge block 3 are each fixed with a material blocking ring 31, and the roller coating mechanism 20 further comprises a rotating driving assembly 7, which comprises a second servo motor, the second servo motor is in opposite fixed connection with the paint tank 1, the output end of the second servo motor is fixed with a rotating frame 32, the end portion of the rotating frame 32 is arranged in the transfer sponge block 3 along the axial direction of the transfer sponge block 3, and the rotating frame 32 is in fixed connection with the material blocking ring 31.

[0076] The second servo motor can drive the transfer sponge block 3 to rotate around its own axis, and in this embodiment, the transfer sponge block 3 rotates in a circumferential swinging manner, so that the transfer sponge block 3 can rotate relative to the flow equalization box 5 to uniformly absorb paint from the flow equalization box 5, and at the same time, the transfer sponge block 3 rotates relative to the brush roller 2, so that the same amount of paint on each part of the transfer sponge block 3 is uniformly transferred to the brush roller 2, thereby improving the uniformity of the brush coating.

[0078] Embodiment 5 is based on embodiment 4 and is provided with the following settings, as shown in Figure 9 the roller coating mechanism 20 further comprises a second reciprocating assembly 9, which can be a pneumatic cylinder or an electric cylinder, the second reciprocating assembly 9 is in opposite fixed connection with the paint tank 1, the second servo motor is in opposite sliding connection with the paint tank 1, and the driving end of the second reciprocating assembly 9 is in fixed connection with the second servo motor, so that the second reciprocating assembly 9 indirectly drives the transfer sponge block 3 to reciprocate along its own axial direction.

[0079] In this way, the transport sponge block 3 has two movement modes of rotation and axial reciprocating movement, and the two movement modes are superimposed, so that the contact range between the transport sponge block 3 and the annular flow uniformizing box 5 is increased, and the range of the paint in the flow uniformizing box 5 flowing to the transport sponge block 3 is larger, so as to improve the paint absorption amount of the transport sponge block 3.

[0080] Secondly, the two movements are superimposed, which can greatly increase the contact area between the transport sponge block 3 and the brush roller 2 per unit time, so as to improve the paint transport efficiency.

[0081] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so: any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
