Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and more specifically, to a clogging-resistant spraying equipment. Background Technology

[0002] Anti-clogging spraying equipment is a professional coating equipment specifically designed to solve the nozzle clogging problem commonly found in traditional spraying equipment. It is widely used in automobile manufacturing, furniture painting, industrial product coating and other fields.

[0003] When the spraying equipment is in use, the paint is drawn out through the material pipe by the liquid pump and discharged through the nozzle. After the paint is sprayed out of the nozzle, it can be used to spray the product. However, during the spraying process, if the product position is changed or a different product is changed, the nozzle needs to be closed in order to save paint consumption. At this time, the paint remaining in the material pipe is prone to sedimentation, which will lead to the problem of nozzle blockage. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0026] Please see Figures 1-4 In this utility model: an anti-clogging spraying device includes a material cylinder 1, a stirring mechanism 2 on the material cylinder 1, two sets of equally spaced heating rods 3 fixedly connected to the inner wall of the material cylinder 1, a discharge pipe 4 connected to the bottom of the material cylinder 1, a liquid pump 5 installed on the discharge pipe 4, a nozzle 6 installed at the bottom end of the discharge pipe 4, a return pipe 7 connected to the discharge pipe 4, a solenoid valve 8 installed on both the return pipe 7 and the discharge pipe 4, the solenoid valve 8 on the discharge pipe 4 being located below the return pipe 7, a preheating pipe 9 connected to the top end of the return pipe 7, the preheating pipe 9 being serpentinely distributed inside the material cylinder 1, and the top end of the preheating pipe 9 being connected to the material cylinder 1; the stirring mechanism 2 includes a motor 201, a rotating rod 202 fixedly connected to the output shaft of the motor 201, the bottom end of the rotating rod 202 penetrating and extending into the interior of the material cylinder 1, and two sets of equally spaced stirring rods 203 fixedly connected to the rotating rod 202.

[0027] In this invention, during use, the motor 201 and heating rod 3 are first turned on. The heating rod 3 heats the coating, effectively reducing its viscosity, improving its fluidity, and minimizing clogging. Furthermore, the motor 201, through the rotating rod 202, drives the stirring rod 203 to rotate, ensuring uniform mixing of the coating and preventing sedimentation, further reducing clogging. During spraying, the solenoid valve 8 on the discharge pipe 4 and the liquid pump 5 are first turned on. The liquid pump 5 draws the coating through the discharge pipe 4, and the coating is then sprayed from the nozzle 6, thus achieving product coating. When changing the spraying area or the nozzle... When coating a product, close the solenoid valve 8 on the discharge pipe 4 to prevent paint from being sprayed from the nozzle 6, thus saving paint. At the same time, open the solenoid valve 8 on the return pipe 7, allowing paint to flow from the discharge pipe 4 into the return pipe 7 and into the preheating pipe 9. The paint then flows back from the preheating pipe 9 into the barrel 1, keeping the paint flowing between the discharge pipe 4 and the return pipe 7. This keeps the paint in the discharge pipe 4 in a continuous state of flow, preventing the paint from becoming stagnant and settling. After changing products, switch the two solenoid valves 8, and the paint will be sprayed from the nozzle 6 to coat the next product.

[0028] During the spraying process, the paint may settle and cool down in the return pipe 7. When the spraying is paused, the paint will flow back into the return pipe 7. The paint will then push the settled and cooled material into the preheating pipe 9. The paint flows in the preheating pipe 9, and the preheating pipe 9 will exchange heat with the hot paint inside the barrel 1, thereby achieving the effect of preheating the paint in the return pipe 7. The preheated paint will then flow back into the barrel 1, reducing the impact on the paint inside the barrel 1. After the settled paint enters the barrel 1, it will be stirred evenly by the stirring rod 203, completing the treatment of the settled and cooled paint, and further preventing the paint from clogging.

[0029] Please see Figures 1-4 The discharge pipe 4 is fixedly connected to a cleaning pipe 10, which is located below the solenoid valve 8 on the discharge pipe 4. A one-way valve 11 is installed on the cleaning pipe 10, and an air pump 17 is installed on the cleaning pipe 10.

[0030] In this invention, when replacing a product, if it takes a long time and the paint may become clogged inside the nozzle 6 and at the bottom of the discharge pipe 4, the air pump 17 is turned on. The air pump 17 will input air into the discharge pipe 4 through the cleaning pipe 10. The air will push out the material in the discharge pipe 4 and the paint in the nozzle 6, thereby achieving the effect of cleaning the nozzle 6 and the paint in the discharge pipe 4 in the area where the nozzle 6 is located, thus avoiding the situation where the paint becomes clogged inside the nozzle 6 when the work is stopped for a long time.

[0031] Please see Figures 1-4 The cleaning tube 10 is fitted with a mounting sleeve 12 that is threadedly connected to it on the left side, and a filter screen 13 is fixedly connected to the left side of the mounting sleeve 12.

[0032] In this invention, the installation cylinder 12 and the filter screen 13 work together to filter the air entering and exiting the discharge pipe 4, thereby preventing dust in the air from contaminating the nozzle 6 or the discharge pipe 4, and thus improving the practicality of the device.

[0033] Please see Figure 4 The inner wall of the discharge pipe 4 is fixedly connected to a filter plate 14, which is located above the cleaning pipe 10.

[0034] In this invention, the filter plate 14 can filter the paint flowing into the nozzle 6, further preventing the paint particles from clogging the nozzle 6, thereby improving the practicality of the device.

[0035] Please see Figure 4 Among them: the discharge pipe 4 is fixedly connected to the waste discharge pipe 15, the left end of the waste discharge pipe 15 is located above the filter plate 14, and the waste discharge pipe 15 is equipped with a solenoid valve 16.

[0036] In this invention, when cleaning the nozzle 6, the user opens the solenoid valve 16 on the waste discharge pipe 15. At this time, some of the air flowing into the discharge pipe 4 will flow into the waste discharge pipe 15 and be discharged. During the flow, the air will pass through the filter plate 14 in the opposite direction. When the air passes through, it can achieve the effect of backwashing and cleaning the filter plate 14, thereby improving the practicality of the device.

[0037] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
