Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and in particular to a spraying device for applying anti-scratch and wear-resistant coatings to granite surfaces. Background Technology

[0002] Granite is an acidic igneous rock composed of feldspar, quartz, and mica minerals. Due to its hard and dense texture and rich and beautiful patterns, it is widely used in architectural decoration, sculpture art, and home furnishing. However, even though granite itself has certain wear-resistant properties, its surface is still subject to scratches and wear during long-term use, which damages its appearance and performance. To improve the durability of granite surfaces, people have developed anti-scratch and wear-resistant coating spraying devices for granite surfaces.

[0003] The granite surface scratch-resistant and wear-resistant coating spraying device, through precise control of the spraying process and structural design, evenly covers the granite surface with a wear-resistant coating. While not changing the natural texture of the granite, it gives the granite stronger protective capabilities. The device consists of a paint storage and supply mechanism, a spray gun assembly, and a precision motion mechanism. The paint storage and supply mechanism ensures a stable supply of paint and smoothly delivers the paint to the spray gun. The spray gun can evenly spray the paint. The device can efficiently solve the problems of uneven coating and low efficiency in traditional spraying, and significantly improve the scratch-resistant and wear-resistant performance of the granite surface.

[0004] Although the granite surface anti-scratch and wear-resistant coating spraying device is easy to operate, the capacity of the paint storage tank is too small, requiring frequent paint additions, which interrupts the spraying operation and affects work efficiency. Moreover, adding paint can introduce air or impurities due to improper operation, affecting the performance of the paint and the quality of the coating. The existing solution is to increase the capacity of the paint storage tank and reduce the frequency of paint addition. However, in actual spraying equipment, due to limited space, it is not possible to set the paint storage area too large. Furthermore, if the paint tank is too large, the paint cannot be used in time, resulting in the paint being damaged due to prolonged storage. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a granite surface anti-scratch and wear-resistant coating spraying device, which aims to improve the problem that the space in the existing spraying equipment is limited and cannot completely solve the problem of the small capacity of the paint storage tank.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a granite surface anti-scratch and wear-resistant coating spraying device, comprising a paint bucket and a mobile trolley. A fixing strip is fixedly connected to the right end of the inner wall of the paint bucket, and a motor protective shell is fixedly connected to the left side of the fixing strip. A servo motor is fixedly connected to the top of the inner wall of the motor protective shell, and a rotating shaft is fixedly connected to the output end of the servo motor. Multiple stirring shafts are fixedly connected to the outer wall of the rotating shaft, and two scrapers are fixedly connected to the middle of the outer wall of the rotating shaft. A liquid distribution plate is fixedly connected to the middle of the inner wall of the paint bucket, and a solenoid valve is fixedly connected to the right side of the top of the liquid distribution plate. A liquid level sensor is fixedly connected to the left side of the bottom of the liquid distribution plate, and a vibrator is fixedly connected to the left side of the bottom of the liquid distribution plate. A bushing is fixedly connected to the middle of the liquid distribution plate. A heating wire is fixedly connected to the inner wall of the paint bucket, and a conical base plate is fixedly connected to the bottom of the paint bucket. A bucket lid is rotatably connected to the top of the paint bucket. A cleaning mechanism is provided on the top of the mobile trolley, and the cleaning mechanism is used to accelerate the cleaning speed of the paint bucket.

[0008] The cleaning mechanism includes a water tank, the bottom of which is fixedly connected to the top left side of the mobile trolley. A heater is fixedly connected to the top front side of the water tank, and a high-pressure water pump is fixedly connected to the top right side of the water tank. A water inlet hose is connected to the top of the high-pressure water pump. An annular water box is fixedly connected to the bottom center of the bucket lid, and a rotating nozzle is fixedly connected to the bottom of the annular water box.

[0009] As a further description of the above technical solution:

[0010] A water level plate is fixedly connected to the front side of the water tank, and a buzzer is fixedly connected to the front top of the water tank.

[0011] As a further description of the above technical solution:

[0013] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, a servo motor drives the rotating shaft to rotate, which in turn causes the stirring shaft and scraper to rotate around the axis to stir the paint in the paint bucket. Furthermore, a solenoid valve controls the amount of paint sprayed by the spray gun. Through the joint operation of multiple components, the stirring, heating, precise metering and efficient delivery of the paint are achieved. This prevents the paint from solidifying and caking, avoids waste, ensures the uniformity of the coating, and makes the device easy to clean and maintain, thereby improving the spraying efficiency and quality.

[0023] 2. In this utility model, electrical energy is converted into heat energy by a heater to heat water, and the temperature is precisely controlled until it reaches the preset value. This allows the heated water to enhance the dissolution and cleaning effect on the paint. A high-pressure water pump pressurizes the water and delivers it to the annular water box through the water inlet hose. The annular water box then evenly distributes the water flow to ensure that the pressure of each rotating nozzle is consistent. The nozzles rotate using the reaction force generated by the change in the direction of the water flow, and the fan-shaped or circular water flow washes the barrel wall in all directions, ensuring thorough cleaning without dead corners and efficiently removing residual paint.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a granite surface anti-scratch and wear-resistant coating spraying device, including a paint tank 1 and a mobile trolley 2. A fixing strip 4 is fixedly connected to the right end of the inner wall of the paint tank 1. The fixing strip 4 is used to fix a motor protective shell 5 and a servo motor 6. The motor protective shell 5 is fixedly connected to the left side of the fixing strip 4. The motor protective shell 5 is used to protect the servo motor 6. The servo motor 6 is fixedly connected to the top of the inner wall of the motor protective shell 5. A rotating shaft 7 is fixedly connected to the output end of the servo motor 6. The rotating shaft 7 is used to transmit power. Multiple stirring shafts 8 are fixedly connected to the outer wall of the rotating shaft 7. The multiple stirring shafts 8 stir the raw materials in the device to prevent solidification. Two scrapers 9 are fixedly connected to the middle of the outer wall of the rotating shaft 7. The two scrapers 9 allow the paint at the top of the dispensing plate 10 to flow down from the opening where the solenoid valve 11 is located. The dispensing plate 10 is fixedly connected to the middle of the inner wall of the paint tank 1. The dispensing plate 10 controls the amount of paint sprayed, so that a large amount of paint can be stored in the upper layer. A solenoid valve 11 is fixedly connected to the top right side of the dispensing plate 10. Valve 11, via solenoid valve 11, controls when the paint can flow downwards. A level sensor 12 is fixedly connected to the bottom left side of the distributor plate 10, which detects the amount of paint below the distributor plate 10. A vibrator 14 is fixedly connected to the bottom left side of the distributor plate 10, ensuring no paint residue remains on the surface of the distributor plate 10. A bushing 16 is fixedly connected to the middle of the distributor plate 10, and the bushing 16 is rotatably connected to the rotating shaft 7, preventing paint from spilling from the connection between the rotating shaft 7 and the distributor plate 10. A heating wire 13 is fixedly connected to the inner wall of the paint bucket 1. The heating wire 13 heats the inside of the paint bucket 1 to prevent the paint from caking and to keep some of the paint at a suitable working temperature. A conical bottom plate 15 is fixedly connected to the bottom of the paint bucket 1. The conical bottom plate 15 can prevent paint residue from remaining in the paint bucket 1. A bucket lid 17 is rotatably connected to the top of the paint bucket 1. The bucket lid 17 is used to inspect the inside of the paint bucket 1. A cleaning mechanism 3 is set on the top of the moving trolley 2. The cleaning mechanism 3 is used to speed up the cleaning of the paint bucket 1.

[0033] Specifically, the lid 17 is opened, and the scratch-resistant and wear-resistant coating is poured into the coating container 1. Due to the presence of the distributor plate 10, the coating is initially stored in the space above the distributor plate 10. The servo motor 6 is turned on to drive the rotating shaft 7 to rotate. Multiple stirring shafts 8 on the outer wall of the rotating shaft 7 rotate accordingly, stirring the coating above the distributor plate 10 to prevent the coating from solidifying and to ensure the uniformity and fluidity of the coating. At the same time, the two scrapers 9 in the middle of the outer wall of the rotating shaft 7 also rotate with the rotating shaft 7, scraping the coating at the top of the distributor plate 10 towards the opening of the solenoid valve 11, allowing the coating to flow smoothly to the bottom of the distributor plate 10. The heating wire 13 is activated to heat the coating in the coating container 1, keeping the coating at a suitable working temperature. The temperature is adjusted to further improve the fluidity of the coating. When spraying is required, the solenoid valve 11 is opened, and the coating above the distribution plate 10 flows down through the opening of the solenoid valve 11. The level sensor 12 detects the amount of coating below the distribution plate 10 in real time. When the predetermined amount of coating is reached, the solenoid valve 11 is closed to control the amount of coating sprayed. During the process of the coating flowing down to the distribution plate 10 through the solenoid valve 11, the vibrator 14 is activated to generate vibration, so that the coating on the surface of the distribution plate 10 can flow down completely, avoiding coating residue on the surface of the distribution plate 10. After the spraying work is completed, due to the design of the conical base plate 15, the coating residue in the coating bucket 1 can be easily cleaned.

[0034] Reference Figure 2 , Figure 3 and Figure 5 The cleaning mechanism 3 includes a water tank 301, which can store a large amount of clean water. The bottom of the water tank 301 is fixedly connected to the top left side of the mobile trolley 2. A heater 302 is fixedly connected to the top front side of the water tank 301 to heat the water in the water tank 301. A high-pressure water pump 303 is fixedly connected to the top right side of the water tank 301 to extract and pressurize the water in the water tank 301. The top of the high-pressure water pump 303 is connected to an inlet hose 304 to guide the pressurized water. An annular water box 305 is fixedly connected to the bottom center of the bucket lid 17 to make the water pressure in the multiple rotating nozzles 306 the same. A rotating nozzle 306 is fixedly connected to the bottom of the annular water box 305 to rinse the inner wall of the paint bucket 1.

[0035] Specifically, the heater 302 is turned on to heat the water in the water tank 301. Once the water temperature reaches the set value, heating is stopped. The switch of the high-pressure water pump 303 is turned on, and the high-pressure water pump 303 starts working, drawing water from the water tank 301 and pressurizing it. The pressurized water is then transported to the annular water box 305 through the water inlet hose 304. The lid 17 is closed, so that the annular water box 305 and the rotating nozzle 306 are located inside and above the paint bucket 1. At this time, the pressurized water is evenly distributed in the annular water box 305, ensuring that the water pressure in the multiple rotating nozzles 306 is the same. The rotating nozzles 306 start spraying water to rinse the inner wall of the paint bucket 1 in all directions. The rotating design of the rotating nozzles 306 can ensure that all parts of the inner wall of the paint bucket 1 can be rinsed, effectively removing residual paint. The rinsing time is controlled according to the size of the paint bucket 1 and the amount of paint residue on the inner wall. If there is a lot of paint residue on the inner wall, the rinsing time is appropriately extended, or the rinsing is repeated several times to ensure the cleaning effect.

[0036] Reference Figure 1 , Figure 2 and Figure 3 A water level plate 307 is fixedly connected to the front of the water tank 301, which displays the water level inside the tank. A buzzer 308 is fixedly connected to the top front of the water tank 301, which sounds an alarm when the water level in the tank is too low. A push rod 19 is fixedly connected to the top right side of the moving trolley 2. Two finger grooves 20 are provided on the outer wall of the push rod 19, which facilitates the operator to move the device. An observation window 21 is provided on the front of the paint bucket 1, through which the condition inside the paint bucket 1 can be observed. A fixed frame 22 is fixedly connected to the front side of the observation window 21. A locking lug 24 is fixedly connected to the right end of the bucket lid 17. A latch 25 is fixedly connected to the top right end of the paint bucket 1. The bucket lid 17 is locked by the locking lug 24 and the latch 25. A rubber ring 23 is fixedly connected to the bottom end of the bucket lid 17. The rubber ring 23 adopts a ring design. The rubber ring 23 can prevent dust and impurities from entering the device. A control panel 18 is fixedly connected to the middle right end of the paint bucket 1. The control panel 18 is electrically connected to the servo motor 6, the solenoid valve 11, the liquid level sensor 12 and the heating wire 13 respectively.

[0037] Specifically, before or during use of the device, the operator can check the water level in the water tank 301 by observing the water level plate 307 on the front of the water tank 301 to determine if there is enough clean water for cleaning or other related operations. When the water level in the water tank 301 drops to the preset low water level value, the buzzer 308 sounds an alarm to remind the operator that the water level in the water tank 301 is too low and needs to be replenished in time. When it is necessary to move the spraying device, the operator holds the push rod 19 on the top right side of the moving trolley 2. The two finger grooves 20 on the outer wall of the push rod 19 allow the operator's fingers to grip the push rod 19 better, increasing the comfort and stability of the grip. During the spraying process, the operator can observe the condition inside the paint bucket 1 through the observation window 21 on the front of the paint bucket 1. The fixing frame 22 serves to fix and protect the observation window 21, ensuring that the observation window 21 does not loosen or get damaged during use. When it is necessary to add paint to the paint bucket 1, the connection between the latch 25 at the top right end of the paint bucket 1 and the locking lug 24 at the right end of the lid 17 is released. After opening the lid 17, the corresponding operation is performed. After the operation is completed, the lid 17 is put back on the paint bucket 1, so that the rubber ring 23 at the bottom of the lid 17 fits tightly with the mouth of the paint bucket 1, effectively sealing the mouth and preventing external impurities from entering the paint bucket 1 and affecting the quality of the paint. Then, the locking lug 24 and the latch 25 are connected to lock the lid 17, ensuring the stability of the lid 17. The operator can directly control the servo motor 6, solenoid valve 11, liquid level sensor 12 and heating wire 13 through the control panel 18, thereby operating the device.

[0038] Working principle: By opening the lid 17, the scratch-resistant and wear-resistant coating is poured into the coating tank 1. The distributor plate 10 divides the interior of the coating tank 1 into upper and lower spaces, allowing the coating to initially accumulate above the distributor plate 10. The servo motor 6 is activated, driving the rotating shaft 7 to rotate, which in turn causes the stirring shaft 8 to agitate the coating, preventing it from solidifying and maintaining its uniformity and fluidity. Simultaneously, the scraper 9 rotates with the rotating shaft 7, scraping the coating on the upper surface of the distributor plate 10 towards the opening of the solenoid valve 11, causing the coating to flow below the distributor plate 10, preparing it for spraying. After the heating wire 13 is activated, it heats the coating in the coating tank 1, bringing it to a suitable working temperature, further improving its fluidity and preventing caking. When spraying is required... When the solenoid valve 11 is opened, the paint above the distributor plate 10 flows down through the opening. When the level sensor 12 detects that the amount of paint below has reached a predetermined value, the system controls the solenoid valve 11 to close, thereby accurately controlling the amount of paint sprayed each time, avoiding paint waste or insufficient spraying, and ensuring the uniformity and consistency of the coating thickness. During the process of the paint flowing down the distributor plate 10 through the solenoid valve 11, the vibrator 14 is activated, generating vibration to make the paint flow down quickly, avoiding paint residue on the surface of the distributor plate 10. After the spraying work is completed, the conical bottom plate 15 at the bottom of the paint bucket 1 causes the residual paint to converge to the bottom due to gravity, reducing paint residue and facilitating subsequent maintenance and reuse.

[0039] Furthermore, after the heater 302 is connected to the power supply, it starts working, heating the water in the water tank 301 by converting electrical energy into heat energy. When the water temperature reaches the preset value, the heater 302 stops heating, thereby maintaining the water temperature within a suitable range to improve the cleaning effect. After the high-pressure water pump 303 starts, the water in the water tank 301 is drawn into the inlet of the pump, giving the water a high pressure. The pressurized water enters the inlet hose 304 through the outlet of the pump, and is then transported to the annular water box 305 through the inlet hose 304. 5. With a large internal space and uniform water flow channels, the incoming high-pressure water can be evenly distributed within the box, ensuring that the water inlet pressure of each rotating nozzle 306 is basically the same. When the high-pressure water enters the nozzle, the water flow direction changes, pushing the nozzle to rotate. As the nozzle rotates, the high-pressure water is sprayed out at a certain angle and speed, forming a fan-shaped or circular water flow, which thoroughly rinses the inner wall of the paint bucket 1. Through the continuous rotation of the rotating nozzle 306, all parts of the inner wall of the paint bucket 1 can be covered, washing away the residual paint and achieving the purpose of cleaning.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
