Description

Technical Field

[0001] The invention relates to the technical field of building decoration equipment, and particularly discloses an automatic spraying machine for wall decoration. Background Art

[0002] During interior and exterior wall renovations, mortar, plaster, putty, and other coatings are applied to the walls. Traditionally, this process is done manually by construction workers, which is not only inefficient but also requires workers to work at height, posing significant safety risks.

[0003] Nowadays, professional spraying equipment is also used in the process of wall construction to automatically spray mortar, plaster, putty powder and other coatings. For example, the utility model patent with application number 202420824892.6 discloses a liftable building wall mortar spraying device, including a stabilizer bar fixedly set at the upper end of the chassis; the upper end of the stabilizer bar is fixedly connected to the fixing plate; the upper end surface of the chassis is rotatably connected to the threaded rod; the upper end surface of the fixing plate is fixedly connected to the motor 1; the output end of the motor 1 passes through the fixing plate and is fixedly connected to the threaded rod; the slide is threadedly connected to the threaded rod; the upper end of the slide is fixedly provided with a transfer chamber; the upper end of the transfer chamber is rotatably connected to the discharge pipe; the outer circumference of the discharge pipe is fixedly connected to gear 1; the upper end of the transfer chamber is fixedly provided with motor 2; the output end of motor 2 is fixedly connected to gear 2; by setting gear 2 and gear 1 to mesh, gear 1 is fixedly connected to the spray head. The spraying device disclosed in the patent can pump out the mortar in the storage box by a pump when spraying paint on the wall, and then spray it on the wall by a nozzle after being transported through a pipeline. It can also move up and down during the construction process, avoiding the construction workers from working at height. However, there are some shortcomings in the actual use of the mortar spraying device: first, the nozzle of the mortar spraying device is fixed, and the discharged mortar is sprayed in a conical diffusion spray. The closer to the center, the higher the mortar flow rate, resulting in the mortar sprayed on the wall being thick in the middle and thin on both sides. Therefore, whether the nozzle moves up and down or horizontally, the uniformity of the wall mortar behind the nozzle cannot be guaranteed; second, before spraying mortar, gypsum or putty powder on the wall, it is necessary to spray tap water to wet it first, and then spray the coating to ensure the adhesion effect of the coating. When using the spraying device, an external tap water pipe is required to wet the wall, and it is not possible to spray tap water to wet the wall first and then spray the coating. Therefore, in response to the above-mentioned deficiencies of the existing mortar spraying devices, the present application proposes an automatic spraying machine for wall decoration that can effectively solve the above-mentioned problems.

[0023] A lifting beam 305 is provided within the gantry 301, along with a lifting transmission assembly that drives the lifting beam 305 up and down. Specifically, the lifting transmission assembly includes two rotating rods 306 rotatably connected to the upper and lower ends of the gantry 301. First transmission wheels 307 are connected to both ends of the rotating rods 306. A first transmission belt 308 is provided between the two vertically aligned first transmission wheels 307. Furthermore, a second motor 309 is mounted on the gantry 301 to drive one of the rotating rods 306.

[0024] The lifting beam 305 is designed with a connecting block at each end fixedly connected to the first transmission belt 308, allowing the lifting beam 305 to move up and down along with the first transmission belt 308. A horizontal transmission assembly is also provided within the lifting beam 305 to drive the movement of the nozzle mechanism 5. The horizontal transmission assembly includes second transmission wheels 310 provided at each end of the lifting beam 305, a second transmission belt 311 provided between the two second transmission wheels 310, and a third motor 312 fixed to the end of the lifting beam 305 and connected to one of the second transmission wheels 310.

[0025] Reference Attachment Figure 5 and attached Figure 6 The nozzle mechanism 5 includes a nozzle base 501. A connecting block connected to the second transmission belt 311 is fixedly connected to the back of the nozzle base 501. A sliding block 502 is also provided on the back of the nozzle base 501. A sliding rod 313 is provided at the lower end of the lifting beam 305 to interact with the sliding block 502, thereby increasing the load-bearing capacity of the entire nozzle base 501. A through hole is formed in the nozzle base 501, through which a plug connector 503 extends. The rear end of the plug connector 503 is connected to the material delivery hose 207. A spring 504 is connected between the nozzle base 501 and the nozzle base 501.

[0026] A telescopic drive member 505 is mounted on top of the nozzle base 501. Specifically, a multi-stage telescopic rod is preferably used for the telescopic drive member 505. A lifting plate 506 is connected to the lower end of the telescopic drive member 505, which moves vertically along the nozzle base 501. A plurality of nozzle guide boxes of varying angles and shapes are then mounted on the lifting plate 506. Specifically, four nozzle guide boxes are provided: a vertical clustering guide box 507, a horizontal clustering guide box 508, a conical diffusion guide box 509, and a conical spray head 510. The rear ends of these four nozzle guide boxes are all open and compatible with the plug connector 503, enabling a sealed connection between the two. Side plates 511 are connected to both side ends of the lifting plate 506, and a recessed guide groove 5111 is provided on the side plate 511 at the same height as each nozzle guide box.

[0027] When the automatic wall decoration sprayer disclosed in this embodiment 1 is in use, the control box 4 opens the solenoid valve 206 connected to the water storage tank 202 and closes the solenoid valve 206 connected to the paint tank 201. At the same time, the telescopic drive member 505 is controlled to shorten, causing the lifting plate 506 to move upward. After the conical spray head 510 on the lifting plate 506 is aligned with the plug connector 503, the telescopic drive member 505 stops operating. At this time, the abutment wheel 513 interacts with the corresponding notch guide groove 5111, and then, under the force of the spring 504, the plug connector 503 is sealed and plugged into the rear end opening of the conical spray head 510. Next, the booster pump 205 is turned on, allowing the water in the water storage tank 202 to flow into the plug connector 503 along the delivery hose 207, and finally dispersed and sprayed onto the wall surface by the action of the conical spray head 510 to wet it.

[0028] Subsequently, the solenoid valve 206 connected to the water tank 202 is closed, and the solenoid valve 206 connected to the paint tank 201 is opened, and then the telescopic drive member 505 is controlled to shorten, so that the lifting plate 506 moves upward, so that the vertical bunching material guide box 507 or the horizontal bunching material guide box 508 and the plug connector 503 are sealed and plugged under the action of the spring. When the vertical bunching material guide box 507 is put into use, the entire spraying moving mechanism 3 controls the nozzle mechanism 5 to move horizontally, so that under the action of the vertical bunching material guide box 507, the sprayed putty powder can be evenly coated on the wall; and when the horizontal bunching material guide box 508 is put into use, the entire spraying moving mechanism 3 controls the nozzle mechanism 5 to move up and down, so that under the action of the horizontal bunching material guide box 508, the sprayed putty powder can be evenly coated on the wall. Example 2

[0029] Example 2 discloses an automatic spraying machine for wall decoration based on the technical solution in Example 1, with another structural design of the nozzle mechanism 5. The similarities with Example 1 will not be described again.

A sliding rod 313 is provided at the lower end of the lifting beam 305 to interact with the sliding block 502, thereby increasing the load-bearing capacity of the entire nozzle base 501. A through hole is formed in the nozzle base 501, through which a plug connector 503 extends. The rear end of the plug connector 503 is connected to the material delivery hose 207. A spring 504 is connected between the nozzle base 501 and the nozzle base 501.

[0031] A switching motor 514 is fixedly connected to the bottom of the nozzle base 501. A loading tray 515 is connected to the motor shaft of the switching motor 514. Multiple nozzle guide boxes of varying angles and shapes are mounted in a circular array on the loading tray 515. Specifically, four nozzle guide boxes are provided: a vertical clustering guide box 507, a horizontal clustering guide box 508, a conical diffusion guide box 509, and a conical spray head 510. The rear ends of these four nozzle guide boxes are open and compatible with the plug connector 503, ensuring a sealed connection between the two.

[0032] A ring plate 516 is provided on the outer circular surface of the loading disk 515, and a notch guide groove 5161 is opened on the ring plate 516 and radially aligned with each nozzle guide box. Then, a connecting strip 512 arranged toward the side plate 511 is fixedly connected to the upper end of the plug connector 503, and an abutment wheel 513 is rotatably connected to the end of the connecting strip 512 to abut against the ring plate 516 and the notch guide groove 5161.

[0033] When the nozzle mechanism 5 disclosed in this embodiment 2 is switched to a different nozzle material guide box and put into use, the switching motor 514 is controlled to rotate the loading plate 515 to a certain angle, and the abutment wheel 513 abuts against the ring plate 516 during the rotation of the loading plate 515, and after being fully aligned, the abutment wheel 513 acts on the corresponding notch guide groove 5111, and then under the action of the spring 504, the plug connector 503 and the corresponding nozzle material guide box are put into use. By controlling the switching motor 514, the loading plate 515 is rotated to a certain angle, and sealed and plugged at the open end of the loading plate 5, it can then be put into use.
