[0007] In a preferred embodiment, a silicone sealing gasket is installed at the portion of the sealing plate that contacts the feed tube.

[0008] In a preferred embodiment, a rotating shaft is provided on one side of the feed tube, one end of the rotating shaft is fixedly connected to the mounting shaft, and a worm gear is installed on the other end of the rotating shaft;

[0009] Two limiting seats are fixed at intervals on one side of the feed tube, and a worm is movably arranged between the two limiting seats. The worm meshes with the worm wheel.

[0010] In a preferred embodiment, one end of the worm gear extends out of the limiting seat and is equipped with a crank.

[0011] In a preferred embodiment, a closed transmission is used between the worm and the worm wheel.

[0012] In a preferred embodiment, a placement seat is fixed on the base, and a storage groove is formed on the surface of the placement seat, with a powder storage tank placed inside the storage groove.

[0013] The beneficial effects of this utility model are:

[0014] When the powder tank of this powder spraying machine needs to be filled, the operator does not need to open the lock on the top cover. He only needs to turn the crank to open the closing plate. At this time, the powder can be poured into the feed hopper. After the filling is completed, turn the crank in the opposite direction until the closing plate contacts the positioning block to close the closing plate. The operation is simple and convenient, which greatly improves the filling speed of the powder tank. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 A perspective view of the main structure of the powder feeding device for a powder spraying machine provided by this utility model; Figure 2 for Figure 1 A magnified structural diagram of A is shown below; Figure 3 The main structural plan view of the powder feeding device for the powder spraying machine provided by this utility model.

[0021] In the specific implementation process, such as Figures 1-3As shown, the device includes a base 1 with several casters 2 mounted on the bottom, a powder tank 3 placed on the base 1, a powder pump 18 installed at the top cover 15 of the powder tank 3, a feed tube 4 connected to the top cover 15 of the powder tank 3, an installation shaft 5 movably installed inside the feed tube 4, and sealing plates 6 fixed on both sides of the installation shaft 5. The sealing plates 6 can seal the opening of the feed tube 4. A silicone sealing gasket is installed at the part of the sealing plate 6 that contacts the feed tube 4 to improve the sealing effect of the sealing plate 6 on the feed tube 4.

[0022] A rotating shaft 7 is provided on one side of the feed tube 4. One end of the rotating shaft 7 is fixedly connected to the mounting shaft 5, and a worm gear 8 is installed on the other end of the rotating shaft 7. Two limit seats 9 are fixed at intervals on one side of the feed tube 4. A worm 10 is movably arranged between the two limit seats 9. The worm 10 meshes with the worm gear 8. One end of the worm 10 extends out of the limit seat 9 and is equipped with a hand crank 11. Turning the hand crank 11 drives the worm 10 to rotate. Under the transmission action of the worm 10 and the worm gear 8, the mounting shaft 5 drives the sealing plate 6 to open. At this time, powder can be poured into the feed hopper 16. The worm 10 and the worm gear 8 adopt a closed transmission, which prevents dust and reduces wear, thus improving its service life. At the same time, this worm 10 adopts an Archimedes single-head worm, which has a self-locking function to prevent the sealing plate 6 from opening during use.

[0023] A placement seat 12 is fixed on the base 1. A storage groove 13 is provided on the surface of the placement seat 12. A powder storage tank 14 is placed inside the storage groove 13. The storage groove 13 can prevent the powder storage tank 14 from falling off when the base 1 moves.

[0024] A feeding hopper 16 is installed at the top of the feeding rectangular tube 4, and a positioning block 17 is fixed on the inner wall of the feeding rectangular tube 4. After feeding is completed, the crank 11 is rotated in the opposite direction until the closing plate 6 contacts the positioning block 17 to complete the closing of the closing plate 6. The operation is simple and convenient, which greatly improves the feeding speed of the powder tank 3.

[0025] The working principle of this utility model is as follows: When the powder tank 3 of this powder spraying machine needs to be filled, the operator does not need to open the lock at the top cover 15. He only needs to turn the crank 11 to drive the worm gear 10 to rotate. Under the transmission action of the worm gear 10 and the worm wheel 8, the mounting shaft 5 drives the sealing plate 6 to open. At this time, the powder can be poured into the feed hopper 16.

[0026] After feeding is complete, turn the crank 11 in the opposite direction until the closing plate 6 contacts the positioning block 17 to close the closing plate 6. The operation is simple and convenient, which greatly improves the feeding speed of the powder tank 3.

[0027] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
