Technical Field

[0001] The utility model belongs to the technical field of spraying equipment, and particularly relates to a spray gun of spraying equipment. Background Art

[0002] As the name implies, a spray gun, "spray" means spraying and painting, and "coat" means paint. A spray gun is a tool for spraying paint, used for surface treatment of products, and is a kind of coating equipment. It atomizes the paint into fine paint droplets through compressed air and sprays them onto the surface of the object to be coated under the drive of air flow. It mainly consists of a spray cap, a nozzle, a needle valve and a gun body, and an air pressure device such as a pressure tank, a pressure barrel, a pump, etc. needs to be connected externally.

[0003] However, when spraying paint at present, workers all spray manually, and the distance during spraying is controlled and adjusted according to their own experience. Such an operation method will, on the one hand, cause the workers to consume a relatively large amount of energy during work, and on the other hand, it will also have certain different effects on the sprayed wall surface, affecting the quality of the product; in view of the above problems, a spray gun of spraying equipment is proposed.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0024] Please refer to all the specification drawings:

[0025] A spray gun of a spraying device includes a spray gun body 1. A filter device 2 is provided on the pipeline of the spray gun body 1, and a spacing adjustment component is provided on the nozzle of the spray gun body 1;

[0026] The spacing adjustment component includes positioning holes 3 uniformly arranged on the spray gun body 1. A connecting ring 4 is rotatably connected to the spray gun body 1 corresponding to the positioning holes 3. A first protrusion 5 is fixedly installed on the connecting ring 4. A positioning rod 6 is inserted into the first protrusion 5. The positioning rod 6 and the positioning hole 3 fit each other. A first spring 7 is fixedly installed on the positioning rod 6, and the first spring 7 is fixedly connected to the first protrusion 5. A second protrusion 8 is provided on the connecting ring 4. Strip-shaped through holes 9 are symmetrically provided on the second protrusion 8. A connecting shaft 10 is slidably connected in the strip-shaped through holes 9. A movable plate 11 is rotatably connected between the connecting shafts 10. A rotary brush 12 is rotatably connected to the movable plate 11. An adjustment mechanism is provided on the second protrusion 8 corresponding to the connecting shaft 10;

[0027] As can be seen from the above description, before use, the worker drives the roller brush 12 to move through the adjusting mechanism and adjusts it according to the required distance. After adjustment, spraying is carried out. When the spraying gun body 1 approaches the wall surface, the roller brush 12 first touches the wall surface, and the roller brush 12 rolls on the wall surface. By transmitting the force to the movable plate 11, the movable plate 11 moves. One end of the movable plate 11 close to the second protrusion 8 abuts against the second protrusion 8, thereby realizing the limit of the distance corresponding to the spraying gun body 1. The worker only needs to keep the spraying gun body 1 almost perpendicular to the wall surface, and the energy consumed by the worker is less, and the spraying effect can be kept stable; according to different spraying directions and the worker's own preferences, the position of the corresponding roller brush can be rotated and adjusted by controlling the insertion connection of the positioning rod 6 and the corresponding positioning hole 3.

[0028] As a technical optimization scheme of the present invention, the adjusting mechanism includes fixing plates 13 symmetrically arranged on the second protrusion 8 corresponding to the strip-shaped through holes 9. A screw rod 14 is rotatably connected between the fixing plates 13 on one side. The screw rod 14 is threadedly connected to the corresponding connecting shaft 10. A knob 15 is rotatably connected to the fixing plate 13, and the knob 15 is fixedly connected to the screw rod 14;

[0029] As can be seen from the above description, by rotating the knob 15, the screw rod 14 is driven to rotate, so that the connecting shaft 10 moves, driving the movable plate 11 to move, thereby realizing the adjustment of the position of the roller brush 12, and the overall operation is convenient.

[0030] As a technical optimization scheme of the present invention, a limiting rod 16 is fixedly connected between the fixing plates 13 on the other side, and the limiting rod 16 is inserted and connected to the corresponding connecting shaft 10;

[0031] As can be seen from the above description, the limiting rod 16 can increase the stability of the movable plate 11 during lateral movement and share the pressure between the connecting shafts 10.

[0032] As a technical optimization scheme of the present invention, the filtering device 2 includes a filter cylinder threadedly connected to the pipeline of the spraying gun body 1, and a filter screen is arranged in the filter cylinder;

[0033] As can be seen from the above description, when the paint enters the spraying gun body 1, it can be filtered to a certain extent first, which has the ability to protect the spraying gun body 1. At the same time, the threaded connection design enables the filtering device 2 to have the ability to be repeatedly disassembled and cleaned, and the overall practicability is better.

[0034] As a technical optimization scheme of the present invention, sliding grooves 17 are symmetrically arranged on the second protrusion 8. A sliding rod 18 is slidably connected to the sliding grooves 17. A second spring 19 is fixedly installed on the sliding rod 18, and the second spring 19 is fixedly connected to the movable plate 11;

[0035] As can be seen from the above description, the sliding rod 18 and the second spring 19 can provide a certain elastic pulling force for the movable plate 11, so that the movable plate 11 presents a certain force to approach the position of the nozzle of the spray gun body 1, and can provide a buffer for the movement of the movable plate 11 for a certain distance; in this structure, when the roller brush 12 touches the wall surface, first the second spring 19 provides the corresponding elastic pulling force to provide a certain buffer for the worker.

[0036] As a technical optimization scheme of the present utility model, a control rod 20 is fixedly installed at one end of the positioning rod 6 extending out of the first protrusion 5;

[0037] As can be seen from the above description, the worker can more conveniently control the telescopic movement of the positioning rod 6 by pulling the control rod 20, and the control is more convenient.

[0038] Working principle:

[0039] Before use, the worker drives the roller brush 12 to move through the adjustment mechanism and adjusts it according to the required distance. After adjustment, spraying is carried out. When the spray gun body 1 approaches the wall surface, the roller brush 12 touches the wall surface first, and the roller brush 12 rolls on the wall surface. By transmitting the force to the movable plate 11, the movable plate 11 moves. One end of the movable plate 11 close to the second protrusion 8 abuts against the second protrusion 8, so as to realize the limit of the distance corresponding to the spray gun body 1. The worker only needs to keep the spray gun body 1 almost perpendicular to the wall surface, and the worker consumes less energy, and the spraying effect can be kept stable; according to different spraying directions and the worker's own preferences, the position of the corresponding roller brush can be rotated and adjusted by controlling the plug-in connection between the positioning rod 6 and the corresponding positioning hole 3.

[0040] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the specific implementation manners is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
