Description

Technical Field

[0001] The utility model relates to the field of spray powder supply, in particular to a spray powder supply device with convenient filling. Background Art

[0002] Spraying is a coating technology that uses a spray gun and other equipment to spray the paint in the form of mist onto the surface of the object to be coated, forming a uniform, smooth and thick coating. The powder supply device of the spraying is an important part of the powder spraying system. The main function of the powder supply device is to take the powder coating from the storage container and transport it to the spray gun or other spraying equipment in a certain way.

[0003] Existing powder supply devices usually adopt manual filling during use, requiring operators to manually pour powder into the powder supply barrel. This method is not only inefficient, but also prone to powder spillage due to improper operation, increasing the cleaning work.

[0004] Therefore, in view of the fact that the filling speed of the above-mentioned powder supply device is easily limited and may cause powder spillage, dust pollution and other problems due to improper operation, a powder supply device for spraying with convenient filling can be designed. Utility Model Content

[0005] In order to overcome the problem of existing powder supply devices, manual filling is usually adopted during use, requiring operators to manually pour powder into the powder supply barrel. This method is not only inefficient, but also prone to powder spillage due to improper operation, increasing the problem of cleaning work.

[0006] The technical solution of the utility model is: a powder supply device for spraying with convenient filling, comprising a spray gun body, a nozzle and a feeding assembly; a spray joint is fixedly installed at the front end of the spray gun body, a spray hole is opened in the center of the spray joint, an air intake joint is fixedly installed at the rear end of the spray gun body, an air intake hole is opened in the center of the air intake joint, the outer end sleeve of the spray joint is provided with the nozzle, a powder filling hopper is provided at the center of the upper end of the spray gun body, a feeding assembly for quickly filling a powder bottle is provided above the powder filling hopper, and the feeding assembly comprises a fixing frame and an angle iron.

[0007] Preferably, by combining the fixing frame and the angle iron, compared with the powder supply device currently on the market, the present application forms a storage space for accommodating powder bottles at the upper end of the spray gun body by combining two sets of fixing frames and two sets of angle irons. The storage space allows the staff to pre-load multiple powder bottles in the storage space, thereby saving the staff's filling time during use.

[0008] Preferably, a locking groove is provided at the outer ends of both sides of the spray gun body, a powder feeding hole is provided at the center of the spray gun body, a powder trough is provided inside the powder filling hopper, the injection hole, powder feeding hole, air inlet and powder trough are connected to each other, a ejector pin is installed at the bottom center of the powder trough, and a magnetic ring is provided at the upper end of the powder filling hopper. Through the combination of the injection hole, powder feeding hole, air inlet and powder trough, the staff can connect the compressed gas tank to the air inlet joint and put the outer end of the injection joint on the nozzle. When the spray powder enters the powder feeding hole from the powder trough, the compressed air enters the powder feeding hole from the air inlet, driving the spray powder to be sprayed out from the injection hole.

[0009] Preferably, the ejector pin is matched with a driver, which is located at the lower end of the spray gun body. A driving handle is fixedly installed at the center of the lower end of the spray gun body. A control switch is provided at the outer end of the driving handle. The driver is combined with the ejector pin, so that when filling is needed, the staff can push the powder bottle to the top of the powder filling hopper, adsorb the bottle mouth of the powder bottle through the magnetic ring, and press the control switch to start the driver. The driver drives the ejector pin to pierce the tin film at the bottle mouth of the powder bottle, so that the spray powder in the powder bottle can enter the powder groove of the powder filling hopper.

[0010] Preferably, two groups of fixing brackets are provided, and the two groups of fixing brackets are respectively located on both sides of the spray gun body. The inner sides of the middle ends of the two groups of fixing brackets are provided with support bars.

[0014] Beneficial effects of the utility model:

[0015] 1. Compared with the powder supply device currently on the market, the present invention forms a storage space for accommodating powder bottles at the upper end of the spray gun body by combining two sets of fixing frames and two sets of angle irons. The storage space allows the staff to pre-load multiple powder bottles in the storage space, thereby saving the staff's loading time during use;

[0016] 2. The combination of the spray hole, powder delivery hole, air inlet and powder trough allows the operator to connect an external compressed air tank through the air inlet joint and put the outer end of the spray joint on the spray head. When the spray powder enters the powder delivery hole from the powder trough, the compressed air enters the powder delivery hole from the air inlet hole, driving the spray powder to be sprayed out from the spray hole. The combination of the driver and the ejector pin allows the operator to push the powder bottle to the top of the powder filling hopper when filling is needed. The bottle mouth of the powder bottle is adsorbed by the magnetic ring, and the driver is started by pressing the control switch. The driver drives the ejector pin to pierce the tin film on the bottle mouth of the powder bottle, so that the spray powder in the powder bottle can enter the powder trough of the powder filling hopper. The support bar can support the bottleneck of the powder bottle when pre-filling to prevent the powder bottle from falling.

[0017] 3. The powder supply bin, the damping groove and the damping strip are combined to enable the powder bottle to be pre-filled through the powder supply bin. At the same time, the damping strip in the damping groove can generate damping when the powder bottle is pre-filled, so that the powder bottle will not easily fall off from the powder supply bin after pre-filling. The clamping block and the clamping groove are combined to enable the loading assembly to be fixed to the outer end of the spray gun body. The secondary mounting block, the mounting hole and the fixing hole are combined to enable the staff to tighten the bolt from the mounting hole through the fixing hole.
