Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a device for applying wall patterns. Background Art

[0002] With the improvement of people's living standards and the change of aesthetic concepts, more and more people begin to pursue unique and artistic environments. Therefore, in modern architectural decoration projects, patterned roller brushes are used to beautify walls. This beautification method of directly applying patterns to walls is not only low-cost, but also can meet different style requirements by choosing different patterns.

[0003] The utility model patent with publication number CN203296348U specifically discloses a wall pattern painting roller, comprising a brush holder and a pattern roller. The brush holder has a handle, and the roller body of the pattern roller is engraved with a pattern. Both ends of the pattern roller have mounting shafts, and the pattern roller is mounted on the brush holder via the mounting shafts. The brush holder also has a paint replenishing device, which includes a paint container and a coating body. One end of the coating body is immersed in the paint container, and the other end is in contact with the pattern roller. The wall pattern painting roller uses the pattern roller to apply the pattern to the wall, and the paint container is used to color the pattern roller. However, because the pattern roller is rotatably mounted on the brush holder via the mounting shaft, if the pattern pattern needs to be changed, the original pattern roller can only be removed and replaced with a pattern roller with a different pattern, which is an extremely cumbersome process. Moreover, if two patterns need to be used alternately, multiple pattern painting devices may even be required, which is not only inconvenient to operate but also easily leads to paint waste.

[0004] In summary, the problem with the existing wall pattern painting equipment is that the wall pattern painting equipment needs to replace the pattern by disassembling the pattern roller, which makes the wall pattern painting equipment cumbersome to operate and easily wastes paint when alternating between two patterns.

[0080] Through this arrangement, the pattern roller 203 can be rotated relative to the wall, and the pattern roller 203 itself is easy to disassemble and replace, which is convenient for workers to clean and maintain.

[0081] A plurality of pattern units 3 are arranged in a circular array along the axis of the pattern roller 203. The pattern units 3 include a hollow pattern 301, a pattern 302, and a pattern moving module 303. The pattern roller 203 is provided with a hollow pattern 301 that penetrates the inner and outer walls of the pattern roller 203. The pattern moving module 303 is slidably installed in the pattern roller 203. The sliding direction of the pattern moving module 303 is parallel to the center line of the hollow pattern 301. The pattern 302 is fixedly installed on the sliding end of the pattern moving module 303. The pattern 302 slides out of the pattern roller 203 through the hollow pattern 301.

[0082] Here, in this embodiment, four pattern units 3 are arranged in a circumferential array along the axis of the pattern roller 203;

[0083] The pattern switching unit 4 includes a push rod 401 and a push block 402. The push rod 401 is rotatably mounted on the roller 202, and the rotation axis of the push rod 401 is parallel to the axis of the roller 202. The push block 402 is fixedly mounted on the push rod 401. The outer wall of the push block 402 is driven by the rotation of the push rod 401 to push the pattern moving module 303 to slide.

[0084] Here, the push rod 401 is a regular square prism, and a circular cavity is provided inside the push rod 401. The push rod 401 is sleeved on the roller 202 through the circular cavity and is rotatably connected to the roller 202. There are two push blocks 402, which are relatively fixedly mounted on the side walls of the push rod 401. The push blocks 402 are rectangular parallelepipeds and the outer walls are provided with guide arc surfaces. By rotating the push rod 401, the outer walls of the two push blocks 402 are driven to simultaneously push the two relative pattern moving modules 303 to slide.

[0085] Here, there is no limitation on the fixing method of the push block 402, which can be connected by screws or clamped;

[0086] Through this arrangement, different pattern units 3 can be pushed directly by rotating the push rod 401, so that the pattern 302 extends out of the pattern roller 203, solving the problem of needing to replace the pattern 302 by disassembling the pattern roller 203, simplifying the operation process, and reducing the waste of pigment of multiple pattern rollers 203.

[0087] In this embodiment, please refer to Figure 3 and Figure 4 , the pattern moving module 303 includes a moving block 3031, a limiting block 3032 and a spring 3033;

[0088] One end of the moving block 3031 is a limiting end, which slides through the annular partition 204 and is located in the first chamber 2031. The other end of the moving block 3031 is a moving end and is located in the second chamber 2032.

[0089] The limiting block 3032 is fixedly mounted on the limiting end. The limiting block 3032 is located in the first cavity 2031 and prevents the limiting end from sliding out of the first cavity 2031.

[0090] Here, there is no limitation on the fixing installation method of the limit block 3032, which can be welding or clamping;

[0091] The pattern 302 is fixedly mounted on the moving end of the moving block 3031;

[0092] Here, there is no limitation on the fixing method of the pattern 302, which can be an integrated type or welded;

[0093] The pushing block 402 is located in the first chamber 2031;

[0094] The push rod 401 is rotated to drive the outer wall of the pushing block 402 to push the limiting block 3032 to slide outward, so as to push the pattern 302 out of the pattern roller 203;

[0095] One end of the spring 3033 is fixedly connected to the limit block 3032, and the other end of the spring 3033 is fixedly connected to the inner wall of the first chamber 2031;

[0096] Here, by rotating the push rod 401, the outer walls of the two pushing blocks 402 are driven to push the two opposing limit blocks 3032 toward the annular partition 204. At this time, the spring 3033 produces elastic deformation and generates elastic force, which causes the two limit blocks 3032 to clamp the pushing blocks 402. The spring 3033 keeps the other two limit blocks 3032 that are not in contact with the pushing blocks 402 in place.

[0097] This arrangement can prevent the pattern 302 from being retracted into the pattern roller 203 due to external force, thereby improving the reliability of the wall pattern painting equipment.

[0098] In this embodiment, please refer to Figure 2 and Figure 5 , the patterns 302 on the plurality of pattern units 3 are all different;

[0099] or the patterns 302 on several of the pattern units 3 are partially identical;

[0100] Here, in this embodiment, because the circumferential array is provided with four pattern units 3, there are two groups of opposing pattern units 3, wherein the pattern 302 and the hollow pattern 301 in one group of pattern units 3 are in the shape of a five-pointed star, and the pattern 302 and the hollow pattern 301 in the other group of pattern units 3 are in the shape of a fish scale;

[0101] Through this setting, the pattern 302 and the hollow pattern in the pattern unit 3 module can be changed according to the application requirements to determine the combination of the pattern 302 in different situations, thereby increasing the combination methods of the patterns.

[0102] In this embodiment, please refer to Figure 2 and Figure 5 , the hollow patterns 301 and the patterns 302 are arranged in a rectangular array along the axis of the pattern roller 203, and the hollow patterns 301 and the patterns 302 correspond one to one;

There are multiple pattern array rings in a rectangular array along the axis of the pattern roller 203. The hollow patterns 301 and patterns 302 in the same pattern unit 3 are in one-to-one correspondence, ensuring that the pattern 302 in the pattern unit 3 can extend out of the pattern roller 203 through the hollow patterns 301.

[0104] In this embodiment, please refer to Figure 2 and Figure 3 , the coating unit 2 also includes a paint box 205 and a coloring roller 206;

[0107] The coloring roller 206 is rotatably mounted in the paint cavity, and the rotation axis of the coloring roller 206 is parallel to the rotation axis of the pattern roller 203. The surface of the coloring roller 206 is in close contact with the surface of the pattern 302 extending out of the pattern roller 203 and colors the surface of the pattern 302.

[0108] Here, the surface of the coloring roller 206 is also evenly provided with a number of annular lines;

[0109] Through this setting, the several annular patterns on the coloring roller 206 can better retain paint and prevent slipping during the coloring process, thereby improving the stability of the wall pattern painting equipment. The annular patterns can store paint and evenly color the pattern 302, avoiding waste of excess paint.

[0110] In this embodiment, please refer to Figure 2 and Figure 3 The coating unit 2 further includes a protective plate 207 ; the protective plate 207 is fixedly mounted on the paint box 205 , and the protective plate 207 is located under the pattern roller 203 , and the protective plate 207 is used to prevent the paint from falling to the ground.

[0111] Here, there is no limitation on the fixing method of the protective plate 207, which can be connected by screws or welding;

[0112] This arrangement prevents excessive paint from dripping onto the ground on the surface of the pattern 302 extending out of the pattern roller 203, thereby protecting the clean environment of the construction site and facilitating cleaning by workers.

[0113] In this embodiment, please refer to Figure 1 and Figure 6 , the screw transmission unit 5 includes a rotation power source 501, a screw 502, a slider 503 and a slide rail 504;

[0114] The screw rod 502 is rotatably mounted on the pattern applying device body 1 , and the rotation axis of the screw rod 502 is perpendicular to the rotation axis of the pattern roller 203 ;

[0118] The slide rail 504 is fixedly mounted on the pattern coating device body 1 , and the guide direction of the slide rail 504 is parallel to the axial direction of the screw rod 502 ;

[0119] The slider 503 is threadedly connected to the screw rod 502. The slider 503 is slidably mounted on the slide rail 504. The slider 503 slides as the screw rod 502 rotates. The slider 503 is fixedly connected to the connecting support block 201.

[0120] Here, the slider 503 is fixedly connected to the connection end of the connection support block 201;

[0121] Through this setting, the slider 503 can slide more stably, and the pattern roller 203 can be more stable during the painting process, avoiding the problem of skewness or shaking that may occur during manual painting, and improving the stability of the wall pattern painting equipment and the painting effect.

[0122] In this embodiment, please refer to Figure 6 and Figure 7 , the screw transmission unit 5 further includes a guide rail 505, a photoelectric switch 506 and a photoelectric baffle 507;

[0125] The guide rail 505 is fixedly mounted on the pattern coating device body 1 , and the guiding direction of the guide rail 505 is parallel to the sliding direction of the photoelectric baffle 507 ;

[0126] The photoelectric switch 506 is slidably mounted on the guide rail 505. The sliding direction of the photoelectric switch 506 is along the guide direction of the guide rail 505. The sliding track of the photoelectric baffle 507 intersects with the light signal emission position of the photoelectric switch 506. The photoelectric switch 506 is used to control the shutdown of the rotation power source 501.

[0127] Here, the working principle of the photoelectric switch 506 controlling the motor is as follows: the photoelectric switch 506 has a U-shaped structure, with a light signal transmitter provided at one end and a light signal receiver provided at the other end. The light signal emitted by the light signal transmitter is received by the light signal receiver. When the photoelectric baffle 507 slides and blocks the light signal from the light signal transmitter, the photoelectric switch 506 releases an electrical pulse signal because the light signal receiver does not receive the light signal, thereby controlling the start and stop of the motor.

[0128] Here, the photoelectric switch 506 in this embodiment can be an Omron U-shaped switch, and the model of the photoelectric switch 506 is E3S-GS3E4;

[0129] Here, a photoelectric moving groove is provided on the photoelectric guide rail 505, and the screw rod 502 transmission module also includes a photoelectric moving block and a top screw. The photoelectric moving block can slide in the photoelectric moving groove along the guide direction of the guide rail 505. A through threaded hole is provided on the photoelectric moving block, and the top screw and the threaded hole are threadedly connected. The photoelectric moving block can use the top screw to support the end face in the photoelectric moving groove to increase the friction of the photoelectric moving block and thus lock the sliding. The photoelectric switch 506 is installed on the photoelectric moving block by a screw; when in use, the position of the photoelectric moving block in the guide rail 505 is first locked, and then the position of the photoelectric switch 506 is locked. When the slider 503 drives the photoelectric baffle 507 to slide to block the light signal emission of the photoelectric switch 506, the photoelectric switch 506 will control the motor to stop.

[0130] Through this setting, the height of the photoelectric switch 506 can be adjusted to adjust the moving distance of the slider 503, and then the painting height of the wall pattern painting device can be adjusted, thereby increasing the applicability of the wall pattern painting device to walls of different heights.

[0131] In this embodiment, please refer to Figure 1 , the wall pattern painting device further includes a moving wheel 6; the number of the moving wheels 6 is four, and the moving wheels 6 are rotatably mounted on the lower end surface of the pattern painting device body 1;

[0132] Here, the moving wheel 6 is rotatably mounted between the lower end surface of the main frame of the equipment and the ground;

[0133] Here, there is no limitation on the rotational installation method of the moving wheel 6, which can be rotationally connected by a bearing or a pin;

[0134] Through this setting, the wall pattern painting equipment can be moved within a range, solving the problem of workers having difficulty in carrying or moving the wall pattern painting equipment.

[0135] The specific usage of this embodiment is as follows:

[0136] When in use, the staff moves the wall pattern painting device to the position where the pattern 302 is to be painted, and adds paint to the paint box 205, then rotates the knob 404 to select the desired pattern 302 and extend the pattern roller 203, then rotates the pattern roller 203 to allow the coloring roller 206 to apply the paint in the paint box 205 to the surface of the pattern 302 extending from the pattern roller 203, and puts the pattern roller 203 close to the wall, adjusts the photoelectric switch 506 to a suitable position according to the height of the wall, then starts the rotation power source 501, and the screw rod 502 rotates to drive the slider 503 to move, thereby causing the pattern roller 203 to roll relative to the wall to paint, and when the photoelectric blocking piece 507 blocks the light signal emission of the photoelectric switch 506, the wall pattern painting device stops working, and at this time, holds the handle and moves the painting device frame horizontally to the next position to be painted;

[0137] When it is necessary to switch the pattern 302, first hold the pattern roller 203 to prevent it from rotating. At this time, rotate the knob 404 to make the patterns 302 of other pattern units 3 extend out of the pattern roller 203. The original pattern 302 will be reset and retracted into the pattern roller 203 by the spring 3033. At this time, the pattern 302 of the wall pattern painting device is successfully switched.

[0138] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
