Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of spraying equipment, and specifically relates to a spraying equipment for decorative coating. BACKGROUND

[0002] Decorative coating plays a role in decorating and protecting the outer wall of a building, making the appearance of the building neat and beautiful, so as to achieve the purpose of beautifying the urban environment and giving people a refreshing space, and can also play a role in protecting the building wall surface and prolonging the service life. Wall decorative coating can be roughly divided into exterior wall coating and interior wall coating, and the decorative coating can be sprayed on the wall surface through a spraying device. However, the existing spraying device has some defects. For example, during use, the operator holds the spraying device for a long time, resulting in high labor intensity, and the handheld operation leads to uneven spraying, affecting the spraying effect. The coating sprayed in the interval is prone to wind drying, which causes the outlet of the spraying device to be easily blocked. Therefore, we propose a decorative coating spraying device.

[0003] The patent with the Chinese patent publication number CN 210857905 U discloses a decorative coating spraying device, which comprises a base, a walking wheel arranged below the base, a rotating shaft for connecting the walking wheel and the base, a moving track arranged at the bottom end of the walking wheel, a placing disc arranged at the top end of the base, an electric telescopic rod arranged on one side of the placing disc, a spray pipe mounted at the free end of the electric telescopic rod, a guide pipe arranged on one side of the spray pipe, a first hollow cylinder arranged on the side of the spray pipe away from the guide pipe, a second hollow cylinder arranged on one side of the first hollow cylinder, and a rotating ring arranged between the second hollow cylinder and the first hollow cylinder. The decorative coating spraying device can stably move the base through the moving track, stably lift the spray pipe through the electric telescopic rod, ensure the stability of spraying, reduce the labor intensity of the operator, and ensure the quality of spraying.

[0004] The device can prevent the coating from precipitating and blocking the spray head during long-term standing, but when spraying the wall surface, a large amount of coating will flow to the ground, causing waste of the coating. SUMMARY

[0005] To solve the above problems, the application provides a spraying equipment for decorative coating, which can avoid waste of the coating by timely smoothing the coating on the wall surface.

[0006] In order to achieve the above object, the technical scheme of the present application is as follows: a spraying device for decorative paint comprises a controller and a support bottom plate, the bottom of the support bottom plate is provided with a pulley structure, the top of the support bottom plate is provided with a vertical rod, the top of the vertical rod is fixedly connected with a support plate and a plurality of support rods, the top of the support rods is fixedly connected with a stirring mechanism, the stirring mechanism extends above the support plate through the support plate, the stirring mechanism is communicated with a pump assembly through a connecting pipe, the pump assembly is communicated with a spraying and smearing mechanism through the connecting pipe, the spraying and smearing mechanism comprises a material conveying pipeline, one end of the material conveying pipeline is communicated with the pump assembly, the end of the material conveying pipeline away from the pump assembly is communicated with a paint spraying head, a plurality of vanes are arranged in the material conveying pipeline, the vanes are fixedly connected with the inner wall of the material conveying pipeline, a Leno triangular pipe is fixedly connected outside the material conveying pipeline, a paint brush is arranged at the end of the Leno triangular pipe close to the paint spraying head, the paint brush and the paint spraying head are in the same plane, and an oval ring is rotatably arranged outside the Leno triangular pipe and is fixedly connected to the top of the support plate.

[0007] After the above scheme is adopted, the following beneficial effects are achieved: during operation, the decorative paint is poured into the stirring mechanism, and then the stirring mechanism will continuously stir the paint to avoid the paint from being deposited for a long time, thereby affecting the subsequent spraying operation; then under the driving of the controller, the pump assembly will be started, after the pump assembly is started, the paint will flow to the material conveying pipeline through the connecting pipe, then the material will flow to the vanes, the vanes will rotate under the impact of the paint, when the vanes rotate, since the vanes are fixedly connected with the wall of the material conveying pipeline, when the vanes rotate under the impact of the paint, the material conveying pipeline will also rotate,

[0008] When the material conveying pipeline rotates, the Leno triangular pipe will rotate in the oval ring, the oval ring will limit the Leno triangular pipe to a certain extent, thereby avoiding the position of the Leno triangular pipe from deviating from the original position where the paint needs to be sprayed, then when the material conveying pipeline and the Leno triangular pipe rotate under the driving of the vanes, the paint will be sprayed from the paint spraying head to the wall surface, and since the Leno triangular pipe and the oval ring are rotatably connected, the paint brush will also smear the wall surface where the paint has been sprayed, thereby realizing that the wall surface is smeared and the paint brush is flattened at the same time, so the paint will be flattened on the wall surface by the paint brush at the moment of spraying, thereby avoiding the paint from flowing to the ground after being sprayed on the wall surface due to inertia, thereby causing waste. Since a certain amount of paint needs to be accumulated and stored before the vanes can rotate, the wall surface can also be intermittently sprayed with paint, which is more in line with the actual operation of the paint.

[0009] Further, the end of the oval ring close to the paint spraying head is provided with an infrared distance sensor, the oval ring is provided with a prompt lamp outside, and the infrared distance sensor and the prompt lamp are signal-connected with the controller.

[0010] Beneficial effects: when the device is placed in front of the wall to be sprayed, the distance between the device and the wall is measured by the infrared distance sensor, and the distance information measured by the infrared distance sensor is sent to the controller. After comparing the distance information with the pre-stored information, the controller will remind you. If the distance is appropriate, the prompt light will be turned on under the control of the controller to remind the staff that they can spray at this time, so that the spraying of the wall is more scientific and data-based, which can maximize the use of limited paint and provide a reference for subsequent spraying of other walls.

[0011] Further, the stirring mechanism includes a stirring box, a motor is arranged at the top of the stirring box, feed pipes are arranged on both sides of the motor, the feed pipes communicate with the stirring box, a rotating shaft is coaxially and fixedly connected to the output shaft of the motor, the rotating shaft extends into the stirring box, and a plurality of stirring blades are arranged on the rotating shaft.

[0012] Beneficial effects: the paint is poured into the stirring box from the feed pipe, and then the motor is started under the control of the controller. When the motor starts, the rotating shaft will rotate under the drive of the motor, and then the stirring blades will rotate in the stirring box, thereby realizing the stirring of the paint in the stirring box. Thus, the paint can be prevented from settling at the bottom of the stirring box after a long period of time, thereby facilitating the spraying operation.

[0013] Further, a sealing ring is arranged at the contact position of the rotating shaft and the stirring box.

[0014] Beneficial effects: the design of the sealing ring can prevent the paint from flowing out of the stirring box along the rotating shaft during stirring in the stirring box.

[0015] Further, the bottom of the stirring box is funnel-shaped.

[0016] Beneficial effects: the funnel-shaped bottom of the stirring box can guide the flow of the paint, so that the paint flows to the center of the stirring box during stirring, thereby preventing the paint from flowing in the dead angle at the bottom of the stirring box and causing waste of the paint.

[0017] Further, a guide block is arranged on the inner wall of the feed pipe and fixedly connected to the inner wall of the feed pipe.

[0018] Beneficial effects: the design of the guide block can make the paint fall near the stirring blades when it is introduced into the stirring box, thereby realizing the stirring of the paint.

[0019] Further, the pulley structure includes a fixed block, a recess is arranged in the fixed block, a buffer spring is arranged in the recess, a sliding block is fixedly connected to the end of the buffer spring away from the recess, the sliding block extends out of the recess through the recess, and a wheel is arranged on the end of the sliding block away from the spring.

[0020] Beneficial effects: when the stirring operation and paint operation can produce a large vibration, thus by the design of the buffer spring, the vibration can be reduced when the operation, so as to reduce the error of the paint spray head on the wall when brushing, so that the paint can be accurately sprayed and sprayed, to avoid the problem of waste and uneven coating.

[0021] Further, the vertical rod is provided with a push rod near the stirring box.

[0022] Beneficial effects: the design of the push rod can facilitate the operator to push the device to paint the wall surface to be painted, and at the same time, the spraying situation of the wall surface is observed and adjusted in coordination with the operator. BRIEF DESCRIPTION OF DRAWINGS

[0029] Pump assembly 14 is communicated with spraying mechanism 3 by connecting pipe, spraying mechanism 3 includes material channel 18, one end of material channel 18 is communicated with pump assembly 14, material channel 18 is communicated with coating spray head 20 at the end away from pump assembly 14, a plurality of fan blades 21 are arranged in material channel 18, fan blades 21 are fixedly connected with the inner wall of material channel 18, material channel 18 is fixedly connected with leno triangular tube 17 outside, leno triangular tube 17 is fixedly connected with coating brush 19 at the end close to coating spray head 20, and coating brush 19 and coating spray head 20 are in the same plane, elliptical ring 22 is fixedly connected on the top of support plate outside leno triangular tube 17, infrared distance measuring sensor is fixedly connected on the end close to coating spray head 20 of elliptical ring 22, and prompt light is fixedly connected outside elliptical ring 22, and infrared distance measuring sensor and prompt light are signal connected with controller.

[0030] The specific implementation process is as follows: in operation, the paint is poured into the stirring box 4 from the feed pipe 5, and then the motor 6 is started under the control of the controller. When the motor 6 is started, the rotating shaft 8 will rotate under the drive of the motor 6, and then the stirring blade will rotate in the stirring box 4, thereby realizing the stirring of the paint in the stirring box 4. Thus, the paint can be prevented from settling at the bottom of the stirring box 4 after being placed in the stirring box 4 for a long time, thereby facilitating the spraying operation. Then, the pump assembly 14 is started under the drive of the controller. After the pump assembly 14 is started, the paint will flow to the material pipe 18 through the connecting pipe, and then the material will flow to the fan blade 21. The fan blade 21 rotates under the impact of the paint. When the fan blade 21 rotates, since the fan blade 21 is fixedly connected with the material pipe 18, when the fan blade 21 rotates under the impact of the paint, the material pipe 18 will also rotate,

[0031] When the material pipe 18 rotates, the Leno triangular pipe 17 will rotate in the oval ring 22. The oval ring 22 will limit the position of the Leno triangular pipe 17 to some extent, thereby preventing the rotating position of the Leno triangular pipe 17 from deviating from the original position to be sprayed. Then, when the material pipe 18 and the Leno triangular pipe 17 rotate under the drive of the fan blade 21, the paint will be sprayed from the paint spray head 20 to the wall surface to be sprayed. Since the Leno triangular pipe and the oval ring 22 rotate together, the paint brush 19 can also be used to wipe the wall surface that has been sprayed with paint, thereby realizing the wiping of the wall surface while the paint brush 19 is flat. Therefore, the paint will be wiped flat on the wall surface by the paint brush 19 at the moment of spraying, thereby preventing the paint from flowing to the ground due to inertia after being sprayed on the wall surface, thereby causing waste. Since a certain amount of paint needs to be accumulated and stored in the material pipe 18 before the fan blade 21 rotates, intermittent spraying of the paint on the wall surface can also be realized, which is more in line with the actual operation of the paint.

[0032] Meanwhile, when the device is placed in front of the wall surface to be sprayed, the distance between the device and the wall surface is measured by the infrared distance sensor, and the distance information measured by the infrared distance sensor is sent to the controller. The controller compares the distance information with the pre-stored information and then gives a reminder. If the distance is appropriate, the prompt light will be turned on under the control of the controller to prompt the staff to perform the spraying operation at this time, so that the spraying of the wall surface is more scientific and data-based. On the one hand, the limited paint can be maximally utilized, and on the other hand, it can serve as a reference for subsequent spraying of other wall surfaces. Moreover, when the stirring operation and the paint operation are performed, a large vibration may be generated. Therefore, through the design of the buffer spring 12, the vibration feeling during the operation can be reduced, so that the error of the paint spray head 20 when brushing the wall surface can be reduced, the paint can be accurately sprayed to the place to be sprayed, and the problems of paint waste and uneven painting can be avoided.
