Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to an automatic spray gun. Background Technology

[0002] Spraying equipment, also known as coating equipment, is a specialized tool for covering metal and non-metal surfaces with protective or decorative layers. Its applications cover multiple industries such as automobile manufacturing, home appliance production, furniture manufacturing, and building decoration. Spray guns are one of the commonly used pieces of equipment in spraying. A spray gun is a tool used to spray paint. It uses different principles to atomize and spray the paint, which can meet the spraying needs of flat workpieces, re-sprayed workpieces, and complex workpieces.

[0003] Currently, existing automatic spray guns mainly consist of a spray gun body, a material delivery hose, and a controller. The paint is delivered to the spray gun body through the material delivery hose and finally sprayed out through the spray gun body. The controller automatically adjusts the speed and flow rate of the paint delivery.

[0004] However, for automatic spray guns like the one mentioned above, the material delivery hoses are mostly connected by bolts, which is time-consuming to disassemble and assemble, inconvenient to replace the material delivery hoses, and prone to loosening after long-term use, resulting in air leakage at the material delivery hose interfaces and affecting the use of the spray gun. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic spray gun.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic spray gun includes a controller and a spray gun body. A control panel is located at one end of the controller, and a connecting pipe is located on one side of the controller. One end of the connecting pipe is connected to a material conveying hose via a flange. A connecting plate is located at one end of the material conveying hose. A connecting slot adapted to the connecting plate is formed at the bottom of the spray gun body. Limit grooves are formed on both inner walls of the connecting slot. Limit blocks are inserted into the inner walls of the limit grooves and are fixedly connected to the connecting plate. A movable groove is formed on the top inner wall of the connecting slot. A limit plate is slidably arranged on the inner wall of the movable groove. Multiple limit springs are fixedly arranged between the limit plate and the movable groove. A limit opening adapted to the limit plate is formed on the top of the connecting plate.

[0007] The present invention is further configured such that the bottom of the limiting plate is designed to be inclined.

[0008] The present invention is further configured such that a material conveying channel is provided inside the spray gun body, and an installation hole is provided on the top of the connecting plate, the installation hole corresponding to the material conveying channel.

[0009] The present invention is further configured such that an installation tube is fixedly provided at one end of the conveying hose, the installation tube is fixedly provided in the installation hole, and a sealing sleeve is provided between the installation hole and the installation tube.

[0010] The present invention is further configured such that a connecting groove is provided at the top of the connecting slot, the connecting groove is connected to the material conveying channel, a connecting hopper is provided inside the connecting groove, and the bottom of the connecting hopper is in contact with the top of the connecting insert plate.

[0011] The present invention is further provided that a sealing ring is provided at the bottom of the connecting bucket.

[0012] The present invention is further configured such that two sliding grooves are formed on the inner wall of the material conveying channel, and a slider is slidably disposed on the inner wall of the sliding groove, and the slider is fixedly disposed between the slider and the connecting hopper.

[0013] The present invention is further configured such that a movable spring is fixedly connected between the slider and the groove.

[0014] The beneficial effects of this utility model are as follows: 1. When installing the automatic spray gun with a conveying hose, first connect one end of the conveying hose to the connecting pipe, and insert the connecting plate at the other end of the conveying hose into the connecting slot. The connecting plate is limited by the limiting block and the limiting groove to prevent it from disengaging from the limiting slot. At the same time, when the limiting plate aligns with the limiting port, the limiting spring pushes the limiting plate into the limiting port, thereby limiting the connecting plate and fixing the conveying hose. When disassembling, press the limiting plate to retract it into the movable groove, and then remove the connecting plate. This facilitates the replacement of the conveying hose.

[0015] 2. This automatic spray gun uses a sealing sleeve to seal the mounting tube, thereby increasing the sealing between the mounting tube and the mounting hole and preventing air leakage.

[0016] 3. After installation, the automatic spray gun pushes the slider and connecting hopper downwards under the elastic force of the movable spring, so that the sealing ring fits tightly with the connecting plate, allowing the paint in the conveying hose to enter the conveying channel. The hopper-shaped connecting hopper prevents paint residue from remaining in the connecting groove. Attached Figure Description
