Description

Technical Field

[0001] This application relates to the field of interior wall construction, and particularly to an interior wall spraying device. Background Art

[0002] During the construction process of a building, spraying and sizing the interior wall of the building is an important process. Traditional spraying methods mainly rely on manual operation, which is not only inefficient but also difficult to guarantee the spraying quality. For example, there is cross-spraying. When spraying and sizing some places for the first time, and then spraying and sizing other positions for the second time, there is an overlap with the position sprayed and sized for the first time. The overlapping places form two layers of sizing, which may lead to inconsistent colors and color differences. Utility Model Content

[0003] In order to improve the problem that color differences may be caused by manual spraying and sizing, this application provides an interior wall spraying device.

[0004] An interior wall spraying device provided by this application adopts the following technical solution:

[0005] An interior wall spraying device includes a spraying mechanism for spraying and sizing. A lateral displacement mechanism for driving the spraying mechanism to perform lateral displacement is arranged on the spraying mechanism. A longitudinal displacement mechanism for driving the lateral displacement mechanism to perform longitudinal displacement is arranged on the lateral displacement mechanism. The displacement direction of the longitudinal displacement mechanism is perpendicular to the displacement direction of the lateral displacement mechanism.

[0006] By adopting the above technical solution, the wall is sprayed and sized by the spraying mechanism. The lateral displacement mechanism automatically and uniformly drives the spraying mechanism to perform spraying and sizing processing to ensure the spraying and sizing quality. Then, after the spraying and sizing of a wall at one height is completed by the longitudinal displacement mechanism, it automatically switches to another height and sprays and sizes again, realizing automated and intelligent construction, greatly improving the efficiency and also ensuring the same quality.

[0007] Optionally, the lateral displacement mechanism includes a base. The longitudinal displacement mechanism includes a lifting driving member arranged on the base. A lifting sleeve is rotatably arranged on the base. The lifting driving member is used to drive the lifting sleeve to rotate. A lifting screw rod is sleeved and threadedly connected inside the lifting sleeve. Both ends of the lifting screw rod are used to abut against the ceiling or the ground.

[0008] By adopting the above technical solution, the lifting driving member drives the lifting sleeve to rotate, thereby driving the base to perform lifting and sliding on the lifting screw rod, which is convenient and fast. Both ends of the lifting screw rod abut against the ceiling and the ground to improve stability.

[0009] Optionally, a flexible abutting block is provided at the upper end of the lifting screw rod. The flexible abutting block is used to abut against the ceiling and deform by extrusion. A small jack is provided at the lower end of the lifting screw rod. The small jack is used to jack the lifting screw rod towards the ceiling.

[0010] By adopting the above technical solution, the lifting screw rod is jacked up by the small jack so that the flexible abutting block deforms and abuts tightly, increasing the contact area and further improving the stability.

[0011] Optionally, the number of the bases is at least two. The lateral displacement mechanism further includes a lateral screw rod and a lateral limiting rod arranged between the two bases. A spraying seat is threadedly connected to the lateral screw rod. The lateral limiting rod penetrates through the spraying seat to limit the spraying seat. A lateral driving assembly for driving the lateral screw rod to rotate is provided on the base.

[0012] By adopting the above technical solution, the two bases limit the rotation of each other, so that the lifting and sliding on the lifting screw rod will not rotate, improving the stability of lifting; at the same time, by rotating the lateral screw rod and limiting the rotation through the lateral limiting rod, the spraying seat is driven to slide laterally, which is convenient and fast.

[0013] Optionally, the lateral driving assembly includes a lateral sleeve rotatably arranged on the base and a lateral driving member for driving the lateral sleeve to rotate. The lateral sleeve is sleeved on the lateral screw rod. A tightening nut is threadedly connected through the lateral sleeve. The tightening nut is used to abut tightly against the lateral screw rod.

[0014] By adopting the above technical solution, the lateral screw rod slides in the lateral sleeve, and then the fixation between the lateral screw rod and the lateral sleeve is realized through the tightening nut, so that the lateral sleeve can adapt to lateral screw rods of different lengths. Also, when the distance between the two bases is different for the same lateral screw rod, the lateral screw rod can still be adapted to be in the lateral sleeve, greatly expanding the adaptation range.

[0015] Optionally, an adjustment groove is formed in the spraying seat. A buffer plate and an adjustment member are slidably arranged in the adjustment groove. A buffer spring is arranged between the buffer plate and the adjustment member. The spraying mechanism is arranged on the buffer plate. A pressure detection member for detecting the pressure of the buffer spring is arranged on the adjustment member to obtain a detected pressure value. The position of the adjustment member is adjusted through the detected pressure value, so as to control the detected pressure value to be kept within the range of a preset pressure threshold.

[0016] By adopting the above technical solution, the pressure of the spraying mechanism on the wall is detected by the pressure detecting member and the buffer spring, and the distance between the spraying mechanism and the wall is adjusted by adjusting the position of the adjusting member, so as to keep the distance between the spraying mechanism and the wall stable, reduce the probability that the connection line between the two bases is not parallel to the wall, resulting in the distance between the spraying mechanism and the wall becoming larger or smaller when the spraying mechanism slides horizontally, and causing uneven spraying, and improve the spraying quality.

[0017] Optionally, at least two adjustment grooves are provided, and the two adjustment grooves are distributed along a direction perpendicular to the sliding direction of the spraying seat.

[0018] By adopting the above technical solution, the spraying mechanism corresponding to the previous adjustment groove performs spraying construction, while the spraying mechanism corresponding to the other adjustment groove does not perform spraying construction, but only plays a role in pressure testing, and then calculates the corresponding result signal. Then, when moving to the height corresponding to the previous other adjustment groove after the previous construction is completed, the result signal obtained last time is directly used for spraying construction, and the result signal is obtained in advance to facilitate the adjustment of the next construction, greatly improving the spraying quality and reducing the probability that the spraying is still uneven due to the delay in calculation and adjustment.

[0019] Optionally, it includes a processor and a rotation detecting member. The rotation detecting member is used to detect the rotation angles of the lifting screw rod and the horizontal screw rod and obtain rotation angle values. The processor receives the rotation angle values and the detected pressure values, and after data processing, outputs corresponding result signals to the adjusting member to adaptively adjust the spraying pressure of the spraying mechanism, outputs the result signals to the lifting driving member to control the spraying seat to automatically switch to the next height to be sprayed after spraying is completed, and outputs the result signals to the horizontal driving assembly to perform spraying again.

[0020] By adopting the above technical solution, intelligent and automated spraying construction is realized through the processor, greatly improving the construction efficiency.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. Realize automated and intelligent construction, greatly improving the efficiency and ensuring the same quality.

[0023] 2. Obtain the result signal in advance to facilitate the adjustment of the next construction, greatly improving the spraying quality and reducing the probability that the spraying is still uneven due to the delay in calculation and adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0030] The following further elaborates on the present application in conjunction with the attached Figures 1-5 drawings.

[0031] An embodiment of the present application discloses an interior wall spraying device. Referring to Figure 1 , the interior wall spraying device includes a spraying mechanism 1 for spraying sizing. In this embodiment, the direction pointed by the gravity direction is down, the direction opposite to down is up, the longitudinal direction is the up and down direction, the lateral direction is the left and right direction, and the direction perpendicular to the up and down direction is the left and right direction. A lateral displacement mechanism 2 for driving the spraying mechanism 1 to perform lateral displacement is installed on the spraying mechanism 1, and a longitudinal displacement mechanism 3 for driving the lateral displacement mechanism 2 to perform longitudinal displacement is installed on the lateral displacement mechanism 2. The displacement direction of the longitudinal displacement mechanism 3 is perpendicular to the displacement direction of the lateral displacement mechanism 2.

[0032] Referring to Figure 1 and Figure 2,The lateral displacement mechanism 2 includes a base 21. The longitudinal displacement mechanism 3 includes a lifting drive member 31 fixedly connected to the base 21. The lifting drive member 31 is a motor. A lifting sleeve 32 is rotatably embedded in the base 21. A gear is sleeved on the rotating shaft of the lifting drive member 31, and the gear meshes with the outer side wall of the lifting sleeve 32, so that the lifting drive member 31 drives the lifting sleeve 32 to rotate. A lifting screw rod 33 is sleeved in the lifting sleeve 32, and the inner side wall of the lifting sleeve 32 is in threaded connection with the thread on the lifting screw rod 33. The lifting screw rod 33 penetrates through the base 21 to the outside and extends in the up and down direction.

[0033] Refer to Figure 1 ,A flexible contact block 34 is fixedly connected to the upper end of the lifting screw rod 33. The flexible contact block 34 is made of a material with a certain degree of flexibility, but the required flexible performance requirements are not high, and a relatively large rigidity is needed, such as hard rubber, which has a certain flexibility while being relatively hard. The flexible contact block 34 is used to contact and deform by extrusion on the ceiling. A small jack 35 is fixedly connected to the lower end of the lifting screw rod 33. The small jack 35 is usually a manually controlled mechanical type jack, such as a screw jack, a hydraulic jack, etc. In this embodiment, a manual hydraulic jack is used. The small jack 35 is used to push the lifting screw rod 33 towards the ceiling, so as to press the flexible contact block 34 tightly against the ceiling.

[0034] Refer to Figure 1 And Figure 2 ,The number of bases 21 is at least two, and the two bases 21 are used in combination. The lateral displacement mechanism 2 further includes a lateral screw rod 22 and a lateral limiting rod 23 installed between the two bases 21. A lateral driving assembly 25 for driving the lateral screw rod 22 to rotate is installed on the base 21. The lateral driving assembly 25 includes a lateral sleeve 251. The lateral sleeve 251 and a jack 254 are rotatably embedded in the mutually facing side walls of the two bases 21. The lateral screw rod 22 is inserted and slides in the lateral sleeve 251, and the lateral limiting rod 23 is inserted and slides in the jack 254. A spraying seat 24 is threadedly connected to the lateral screw rod 22. The lateral screw rod 22 penetrates through the spraying seat 24, and the lateral limiting rod 23 also penetrates through the spraying seat 24 to limit the spraying seat 24.

[0035] Refer to Figure 1 And Figure 2, the lateral driving assembly 25 further includes a lateral driving member 252 for driving the lateral sleeve 251 to rotate. Among the two matching bases 21, as long as the lateral driving member 252 is installed in one of the bases 21. In this embodiment, the lateral driving member 252 can be a motor. The end of the rotating shaft of the lateral driving member 252 is connected to the outer side wall of the end of the lateral sleeve 251. The extending direction of the rotating shaft of the lateral driving member 252 is coaxially arranged with the lateral lead screw 22, and the rotating shaft of the lateral driving member 252 rotates coaxially with the lateral sleeve 251 to drive the lateral sleeve 251 to rotate the lateral lead screw 22. The lateral sleeve 251 is sleeved on the outer circle of the lateral lead screw 22, and a tightening nut 253 is threadedly connected through the lateral sleeve 251. The end of the tightening nut 253 located inside the lateral sleeve 251 is used to press against the outer side wall of the lateral lead screw 22.

[0036] Refer to Figure 3 , on the side wall of the spraying seat 24 facing the wall to be sprayed, at least two adjustment slots 4 are opened. A buffer plate 41 and an adjustment member 42 slide in the adjustment slots 4. The buffer plate 41 is located at a position close to the opening surface of the adjustment slot 4, while the adjustment member 42 is located at a position far from the opening surface of the adjustment slot 4. The buffer plate 41 slides in the adjustment slot 4 and is difficult to fall out. The buffer plate 41 can be limited by the constricted opening design of the adjustment slot 4 or by means of limiting. The adjustment member 42 includes an adjustment plate 421, an adjustment driving member 422, and an adjustment lead screw 423. The adjustment driving member 422 is fixedly connected to the bottom wall of the adjustment slot 4 facing its own opening surface. In this embodiment, the adjustment driving member 422 can be a motor. The rotating shaft of the adjustment driving member 422 extends in the direction pointing to the buffer plate 41. The adjustment lead screw 423 is connected to the rotating shaft of the adjustment driving member 422. The adjustment lead screw 423 is inserted through the adjustment plate 421 and is threadedly connected to the adjustment plate 421. A buffer spring 43 is fixedly connected between the buffer plate 41 and the adjustment plate 421. One end of the buffer spring 43 is fixedly connected to the side wall of the buffer plate 41 facing away from the opening surface of the adjustment slot 4, and the other end of the buffer spring 43 is fixedly connected to the side wall of the adjustment plate 421 facing the opening surface of the adjustment slot 4. The buffer spring 43 expands and contracts along the direction of pushing the buffer plate 41 out of the adjustment slot 4.

[0037] Refer to Figure 3 And Figure 4 And Figure 5, the spraying mechanism 1 is installed on the side wall of the buffer plate 41 facing the outside of the adjustment slot 4. In this embodiment, the spraying mechanism 1 includes a spray gun and a spraying roller. The spraying roller must be installed on the buffer plate 41, while the spray gun can be installed on the buffer plate 41 or not. The number of spraying rollers corresponds one-to-one with the number of buffer plates 41. That is, since there are two adjustment slots 4, there are also two spraying rollers, and only one spray gun is needed. The two adjustment slots 4 are distributed vertically along the direction of gravity. A pressure detection member 44 for detecting the pressure of the buffer spring 43 is installed on the adjustment plate 421. In this embodiment, the pressure detection member 44 can be a pressure sensor, and the position of the pressure detection member 44 corresponds to the position of the buffer spring 43, so that after the buffer spring 43 is compressed, it transmits the pressure to the pressure detection member 44 to obtain a detected pressure value, and the adjustment driving member 422 is controlled through the detected pressure value, thereby adjusting the position of the adjustment plate 421, so as to control the detected pressure value to be kept within the range of a preset pressure threshold.

[0038] Referring to Figure 5 , it further includes a processor 5 and a rotation detection member 51. In this embodiment, the rotation detection member 51 can be a sensor such as an angular momentum sensor that can detect the rotation angle. The rotation detection member 51 is used to detect the rotation angles of the lifting lead screw 33 and the transverse lead screw 22. That is, a plurality of rotation detection members 51 are installed on the base 21, and the rotation angle values are obtained through the detection of the rotation detection members 51. The processor 5 receives the rotation angle values and the detected pressure values, and after data processing, outputs corresponding result signals to the adjustment driving member 422 to adaptively adjust the roller coating pressure of the spraying roller, outputs the result signals to the lifting driving member 31 to control the spraying seat 24 to automatically switch to the next height to be sprayed after spraying is completed, and outputs the result signals to the transverse driving member 252 to perform transverse displacement spraying again.

[0039] The processor 5 can include a central processing component such as a CPU or an MPU, or a host system constructed with a CPU or an MPU as the core, including hardware or software. After the measuring instrument has the processor 5, people can freely control the measuring instrument by programming to make it operate according to people's wishes. The processor 5 can control local quantity transfer, remote quantity transfer, remote communication, etc. through an internal protocol. The internal protocol generally refers to all protocols for realizing mutual communication or connection within the same measuring instrument or the same system, including: part or all of the human-computer interaction protocol, software / hardware (interface) protocol, chip bus (C-Bus) protocol, internal bus (I-Bus) protocol, etc. With the development of integrated circuit technology, some that belong to the external bus (E-Bus) protocol are also classified as internal protocols after being integrated into the chip along with the external bus (E-Bus).

[0040] The implementation principle of an interior wall spraying device in an embodiment of the present application is as follows: When spraying, the lateral driving member 252 rotates to drive the lateral lead screw 22 to rotate, thereby driving the spraying seat 24 to slide. The spraying seat 24 drives the spraying mechanism 1 to spray the wall surface. At this time, the processor 5 can calculate the displacement distance of the spraying seat 24 by combining the rotation angle value output by the rotation detection member 51 corresponding to the lateral driving member 252, the parameters of the rotation axis of this lateral driving member 252, the thread inclination angle parameter of the lateral lead screw 22, and the diameter parameter of the lateral lead screw 22. Then, by comparing and judging the displacement distance with a preset maximum displacement threshold, it can be determined whether the spraying is completed. If it is determined that the spraying is completed, a result signal is output to the lateral driving member 252 to stop the operation of the lateral driving member 252, and the operation of the lifting driving member 31 is started. At the same time, the lifting distance of the base 21 can also be calculated by combining the rotation angle value output by the rotation detection member 51 corresponding to the lifting driving member 31, the parameters of the rotation axis of this lifting driving member 31, the thread inclination angle parameter of the lifting lead screw 33, and the diameter parameter of the lifting lead screw 33. Then, by comparing the lifting distance with a preset single-lift threshold, it can be determined whether the distance of one spraying width has been decreased. If it is determined that the distance of one spraying width has been decreased, the processor 5 outputs a result signal to stop the operation of the lifting driving member 31, and at the same time, the operation of the lateral driving member 252 is started again for spraying.

[0041] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
