[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example: Refer to Appendix Figure 1 To be continued Figure 5 As shown, the lifting device is located between the feeding hood 2 and the screening equipment body 1, and is used to lift the powder coating raw material in the feeding hood 2 into the screening equipment body 1.

[0029] The feeding hood 2 is equipped with a cover 3 at the top and a blade 4 that can move linearly at the bottom. During feeding, the packaging bag containing the powder coating raw material is placed inside the feeding hood 2 and the top opening of the feeding hood 2 is covered by the cover 3, so that the packaging bag is in a closed environment. Then, the bottom of the packaging bag is cut open by the linear movement of the blade 4, so that the material flows into the material lifting device and is transported to the main body 1 of the screening equipment. This avoids the situation where the powder is scattered into the air and pollutes the environment due to the manual cutting of the packaging bag in an exposed environment.

[0030] Furthermore, the bottom two sides of the feeding hood 2 along its length have inwardly inclined first sidewalls 5. The two first sidewalls 5 are used to support the powder coating packaging bag. The blade 4 is movably disposed between the two first sidewalls 5. Preferably, the error between the inner cavity and length and width of the feeding hood 2 and the corresponding length and width of the packaging bag is 3-5cm, so that the packaging bag can be placed relatively vertically inside the feeding hood 2. The powder raw material can flow down quickly by cutting the bottom of the packaging bag by the blade 4.

[0031] Furthermore, a guide rod 6 is fixed between the two first sidewalls 5. The blade 4 is slidably sleeved on the guide rod 6 through the guide seat 7. The blade 4 moves linearly through the guide rod 6, so that the blade 4 cuts the linear opening generated at the bottom of the packaging bag for material feeding.

[0032] Furthermore, the bottom of the guide seat 7 has a through hole 8, which is inserted and connected to the guide rod 6. The blade 4 is elastically set on the top of the guide seat 7. The elastically set blade 4 can ensure that the tip of the blade 4 contacts the packaging bag for cutting.

[0033] Furthermore, the top of the guide seat 7 has a connecting part 9, the connecting part 9 has a rectangular movable cavity 10, the bottom of the blade 4 has a slide plate 11 disposed in the rectangular movable cavity 10, and a set of springs 12 are fixed between the bottom of the slide plate 11 and the rectangular movable cavity 10.

[0034] By elastically setting the blade 4 and the pull rod, the spring 12 can keep the blade 4 in contact with the bottom of the packaging bag. By pulling the pull rod, the blade 4 moves linearly along the guide rod 6 to cut the bottom of the packaging bag, allowing the powder raw material to flow into the lifting cylinder 20. The operation is convenient and the feeding process is stable.

[0035] Furthermore, the top of the connecting part 9 has a sealing block 13 covering the rectangular movable cavity 10, and the middle of the sealing block 13 has a movable slot 14. The bottom of the blade 4 is slidably connected to the movable slot 14 to prevent the powder material from flowing into the rectangular movable cavity 10 after cutting the powder material packaging bag.

[0036] Furthermore, the bottom end of the guide seat 7 has a connecting block 15, on which an operating rod 16 parallel to the guide rod 6 is installed. The outer end of the operating rod 16 is inserted and connected to the feeding cover 2, and a handle 17 is fixed to the outer end. The blade 4 can be driven to move linearly along the guide rod 6 by manually pushing and pulling the handle 17, which is convenient and quick to operate.

[0037] Furthermore, the bottom of the feeding hood 2 has two inwardly inclined second sidewalls 18 on both sides in the width direction for guiding the powder raw materials. The bottom of the second sidewall 18 is connected to an arc-shaped guide pipe 19 that communicates with the bottom of the material lifting device, so that the raw materials in the packaging bag can flow into the material lifting device in a concentrated manner.

[0038] Furthermore, the material lifting device includes a lifting cylinder 20, the bottom end of an arc-shaped guide pipe 19 is connected to the lifting cylinder 20, a rotating shaft 21 is installed inside the lifting cylinder 20, a spiral lifting blade 22 adapted to the inner wall of the lifting cylinder 20 is installed on the rotating shaft 21, a drive motor 23 connected to the rotating shaft 21 is installed at the top of the lifting cylinder 20, and the top of the lifting cylinder 20 is connected to the main body 1 of the screening equipment through a feeding pipe 24. The rotating shaft 21 is driven to rotate by the drive motor 23, and the rotating shaft 21 drives the spiral lifting blade 22 to rotate, thereby lifting the powder raw material at the bottom of the lifting cylinder 20 to the top and flowing into the main body 1 of the screening equipment through the feeding pipe 24.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
