[0002] Spraying machine is a kind of spraying equipment which uses spraying technology to spray pressurized atomized paint onto the surface of workpiece. Spraying machine is widely used in watches, jewelry, mobile phones, nameplates, plate making and other workpieces with high spraying quality requirements and fine craftsmanship.

[0003] Existing technologies include the utility model with publication number CN204746671U, which discloses an automatic feeding sprayer, which solves the problem that the sprayer cannot be automatically fed and has low spraying efficiency in the prior art. It includes a raw material barrel, a sprayer body, and an operation interface. The sprayer body is provided with a storage barrel, a powder pump is provided on the sprayer body, and the powder pump is connected with an air pipe, a powder outlet pipe, and a powder suction pipe. A feed pipe is connected between the raw material barrel and the storage barrel, and a controller and an air pump are provided on the feed pipe. Existing sprayers cannot be automatically fed and need to be manually replaced and fed, which not only increases the labor intensity of the user, but also does not improve the work efficiency. The raw material is powder, which is easy to generate dust when feeding, polluting the environment.

[0004] At present, when most spray machines are in use, the user places the device at a place where maintenance is required, then connects the hose to the connecting pipe, and then starts the device to spray paint on the surface of the object. However, when the device is in use and the controller is damaged internally, the user needs to disassemble and repair the controller. When disassembling the controller, tools are required to operate. The use of tools is too cumbersome, resulting in the situation that the user cannot quickly repair the controller. Utility Model Content

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when using the device, the user places the device at a place where maintenance is required, then connects the hose to the connecting pipe, and then starts the device to spray paint on the surface of the object. When the device needs to be used, the user pulls the connecting rod, and then the connecting rod moves to drive the limiting rod to move, and then the movement of the limiting rod drives the first spring to displace and deform to generate elastic force, and then the limiting rod moves away from the surface of the limiting plate. By setting a limiting device, the limiting plate is effectively restricted, which plays a role in protecting the inside of the controller, reducing the need for users to disassemble and repair the controller when the controller is damaged during use, and tools are needed to operate when disassembling the controller.

In the utility model, by setting a connecting device, when the equipment needs to be used, the user pulls the pull rod, and the pull rod moves to drive the second spring to displace and deform to generate elastic force, and the pull rod moves away from the inner wall of the limiting hole, and the rotating rod loses its restraint, and the rotating rod is rotated to separate from the surface of the first connecting ring. By setting a connecting device, the hose is effectively restricted, and the hose and the connecting pipe are connected, which reduces the situation where the hose and the connecting pipe are difficult to connect quickly when the equipment is in use, making it difficult for the user to connect quickly, thereby improving the practicality of the equipment.

[0023] The specific arrangement and function of the limiting device 6 and the connecting device 7 will be described in detail below.

[0024] In this embodiment: the limiting device 6 is arranged on the surface of the controller 3, and the limiting device 6 includes a limiting plate 61 and a connecting block 62, the connecting block 62 is fixedly connected to the upper surface of the controller 3, and the limiting plate 61 is rotatably connected to the surface of the controller 3.

[0025] Specifically, a pull handle 65 is fixedly connected to the upper surface of the limiting plate 61 , and a limiting rod 63 is slidably connected to the inner wall of the connecting block 62 .

[0026] In this embodiment, by providing the limiting plate 61, the inside of the controller 3 can be protected, thereby reducing the difficulty for the user to quickly repair the controller 3 when the device is in use.

[0027] Specifically, a connecting rod 64 is fixedly connected to the side of the limiting rod 63 , and a limiting block 67 is fixedly connected to the upper surface of the controller 3 . The limiting rod 63 is provided to facilitate limiting the limiting plate 61 .

[0028] Specifically, one end of the limiting rod 63 is fixedly connected to a first spring 66 , and one end of the first spring 66 away from the limiting rod 63 is fixedly connected to the surface of the limiting block 67 . The first spring 66 is provided to facilitate applying elastic force to the limiting rod 63 .

[0029] In this embodiment: a connecting device 7 is provided at one end of the connecting tube 5, and the connecting device 7 includes a hose 71 and a connecting head 72. The hose 71 is provided at one end of the connecting tube 5, and the connecting head 72 is fixedly connected to one end of the hose 71. A protrusion 73 is fixedly connected to the side of the connecting head 72, and a first connecting ring 75 and a second connecting ring 76 are provided on the side of the connecting head 72. The first connecting ring 75 and the second connecting ring 76 have grooves 74 formed inside, and the grooves 74 are clamped with the surface of the protrusion 73. The surface of the second connecting ring 76 is rotatably connected with a rotating rod 77. The surface of the first connecting ring 75 is provided with a drawing groove 79, and the surface of the rotating rod 77 is provided with a limiting hole 78.

[0030] In this embodiment: by setting the first connecting ring 75 and the second connecting ring 76 to restrict the connecting head 72, the hose 71 can be connected to the connecting pipe 5, which reduces the situation where the connecting head 72 is difficult to quickly move when the equipment is in use.

[0031] Specifically, a pull rod 710 is slidably connected to the inner wall of the pull groove 79 , and one end of the pull rod 710 is engaged with the inner wall of the limiting hole 78 . The pull rod 710 is provided to facilitate limiting the rotating rod 77 .

[0033] Working principle: When using the device, the user places the device where it needs to be repaired, then connects the hose 71 to the connecting pipe 5, and then starts the device to spray paint on the surface of the object. When the device needs to be used, the user pulls the connecting rod 64, and then the connecting rod 64 moves to drive the limiting rod 63 to move, and then the limiting rod 63 moves to drive the first spring 66 to displace and deform to generate elastic force, and then the limiting rod 63 moves away from the surface of the limiting plate 61. By setting the limiting device 6, the limiting plate 61 is effectively restricted, which plays a role in protecting the inside of the controller 3, reducing the need for the user to disassemble and repair the controller 3 when the controller 3 is damaged during use. Tools are needed to operate when disassembling the controller 3, and the use of tools is too cumbersome, resulting in the user being unable to quickly repair the controller 3, thereby improving the practicality of the device.

[0034] When the device needs to be used, the user pulls the pull rod 710, and the pull rod 710 moves to drive the second spring 711 to displace and deform to generate elastic force. The pull rod 710 then moves away from the inner wall of the limiting hole 78, and the rotating rod 77 loses its restraint. The rotating rod 77 is then rotated to disengage from the surface of the first connecting ring 75. By setting the connecting device 7, the hose 71 is effectively restricted, and the hose 71 and the connecting pipe 5 are connected. This reduces the difficulty of quickly connecting the hose 71 and the connecting pipe 5 when the device is in use, which makes it difficult for the user to quickly connect, thereby improving the practicability of the device.
