[0041] Reference Figure 1~Figure 5 A device for saving spray powder is proposed, which is used for spraying powder on a workpiece 1, including: a spray room 2; a powder spray gun 3, which is movably arranged at one side of the spray room 2, and the spraying end of the powder spray gun 3 extends into the spray room 2; a movable hoisting member 4, which is movably arranged in the spray room 2 and has a hoisting end 401, and the hoisting end 401 is used to drive the workpiece 1 to move and pass through the powder spray gun 3; a powder blocking member 5, which has a channel 501, and the hoisting end 401 moves at the upper part of the channel 501, and the channel 501 has a side opening 502, and the powder spray gun 3 faces the side opening 502; a powder scraping member 6, which is movably arranged on the inner wall of the channel 501 with a powder scraping member 6 for scraping powder on the inner wall of the channel 501.

[0042] In this embodiment, the spraying end (nozzle) of the powder spray gun 3 is deep inside the spray room 2, and can be adjusted in height according to the size of the workpiece 1 and the powder spraying requirements to ensure that the powder is sprayed evenly and effectively onto the surface of the workpiece 1. The mobile hoisting member 4 is arranged on a dedicated track or slide rail inside the spray room 2, and can be moved smoothly and accurately by electric or hydraulic drive. The hoisting member is provided with a hoisting end 401 such as a hook or a clamp for mounting or clamping the workpiece 1 to be sprayed. The powder blocking member 5 is installed in the spray room 2, and its main structure is a channel 501 with an opening. The hoisting end 401 of the mobile hoisting member 4 can carry the workpiece 1 through the channel 501; the channel 501 is provided with a side opening 502, and the setting of the powder blocking member 5 helps to limit the diffusion range of the powder, so that the powder is sprayed more concentratedly onto the surface of the workpiece 1, reducing powder drift and waste. The powder scraping member 6 is installed on the inner wall of the channel 501 of the powder blocking member 5, and can be driven by electric or pneumatic drive to achieve reciprocating movement along the inner wall. The structural design of the powder scraper 6 should ensure that it can effectively scrape off the powder adhering to the inner wall of the channel 501 to prevent powder accumulation from affecting the powder spraying effect and equipment operation. The powder scraping action can be performed intermittently during the spraying process of the workpiece 1, or during the intervals between powder spraying operations or equipment maintenance. The powder-saving spraying device provided in this embodiment effectively improves the utilization rate of powder, reduces environmental pollution, simplifies powder recovery and equipment maintenance work, and has significant economic and environmental benefits through the lifting and lowering movement of the powder spraying gun 3, the moving hoisting part 4 drives the workpiece 1 to move precisely, the powder blocking part 5 guides the powder spraying direction, and the powder scraper 6 removes the inner wall powder.

[0043] Further, the powder scraping member 6 comprises:

[0044] A substrate 601 is movably arranged relative to the powder blocking member 5;

[0045] A movable top plate 602 is movably disposed on the base plate 601, and after moving, it abuts against or cancels the abutment against the powder blocking member 5;

[0046] The elastic member 603 has one end abutting against the movable top plate 602 and the other end abutting against the base plate 601 , thereby providing a force for the movable top plate 602 to abut against the powder blocking member 5 .

[0047] In this embodiment, one end of the elastic member 603 (such as a spring, an elastic rubber block, etc.) abuts against the movable top plate 602, and the other end abuts against the base plate 601, providing the movable top plate 602 with an abutting force that is always directed toward the inner wall of the powder blocking member 5. When the movable top plate 602 moves with the base plate 601, the elastic member 603 is compressed or stretched to maintain close contact between the movable top plate 602 and the inner wall of the powder blocking member 5, thereby ensuring the scraping effect. The elastic force of the elastic member 603 can be adjusted according to actual needs to meet the scraping requirements of powders of different thicknesses. The powder scraping member 6 in this embodiment realizes automatic and continuous scraping of the powder on the inner wall of the powder blocking member 5 through the coordinated work of the base plate 601, the movable top plate 602 and the elastic member 603, effectively preventing powder accumulation from affecting the powder spraying effect and equipment operation, and further improving the powder recovery efficiency and equipment maintenance convenience.

[0048] Furthermore, the powder blocking member 5 has a slide groove 503 , and also includes a slide seat 7 . The slide seat 7 is slidably disposed in the slide groove 503 , and the substrate 601 is disposed on the slide seat 7 .

[0049] In this embodiment, the slide groove 503 extends along the outer wall of the powder blocking member 5, and its shape matches the scraping trajectory of the movable top plate 602. The sliding cooperation between the slide seat 7 and the slide groove 503 can adopt high-precision, low-friction structures such as ball bearings, slider rails, and linear bearings to ensure that the slide seat 7 moves smoothly and stably in the slide groove 503. This embodiment provides a more accurate and stable moving path for the powder scraping member 6 by adding a slide groove 503 and a slide seat 7 structure in the powder blocking member 5, thereby further improving the powder scraping efficiency and effect. At the same time, the cooperation between the slide seat 7 and the slide groove 503 reduces the friction between the powder scraping member 6 and the powder blocking member 5, prolongs the service life of the equipment, and improves the stability of equipment operation.

[0050] Furthermore, the powder blocking member 5 has an upper blocking portion 504 and a lower blocking portion 505 , which are respectively located on both sides of the side opening 502 and are inclined, and the slide groove 503 is synchronously arranged on the upper blocking portion 504 and the lower blocking portion 505 .

[0051] In this embodiment, the powder blocking member 5 is designed to include an upper blocking portion 504 and a lower blocking portion 505, which are respectively located on both sides of the side opening 502 and are inclined. The inclination angles of the upper blocking portion 504 and the lower blocking portion 505 can be adjusted according to the actual powder spraying requirements and the powder recovery effect. The upper blocking portion 504 and the lower blocking portion 505 together constitute the powder guide channel 501, which helps to limit the diffusion range of the powder, so that the powder is sprayed more concentratedly onto the surface of the workpiece 1, and the powder is reduced. The chute 503 is not only arranged on the outer wall of the powder blocking member 5, but also synchronously arranged on the upper blocking portion 504 and the lower blocking portion 505. In this embodiment, by synchronously arranging the chute 503 on the upper blocking portion 504 and the lower blocking portion 505 of the powder blocking member 5, the powder scraping range of the powder scraping member 6 is expanded, ensuring that the inner wall of the powder blocking member 5, the upper blocking portion 504 and the lower blocking portion 505 can be effectively scraped off the powder, further improving the powder recovery efficiency and the convenience of equipment maintenance. At the same time, the cooperation between the slide seat 7 and the slide groove 503 reduces the friction between the powder scraping member 6 and the powder blocking member 5, prolongs the service life of the equipment, and improves the operation stability of the equipment.

[0052] Furthermore, it also includes a linear driving member 8 , one end of which is rotatably arranged on the spray booth 2 and has a driving end 801 , and the driving end 801 is hingedly arranged on the slide seat 7 .

[0053] In this embodiment, one end of the linear drive member 8 (such as an electric push rod, a cylinder, a hydraulic cylinder, etc.) is fixed on the spray booth 2, and a rotation setting is realized through a connection structure such as a bracket or a flange, so as to ensure that the drive member can rotate with a certain degree of freedom to adapt to the movement trajectory of the slide 7 in the slide groove 503 of the powder blocking member 5. The other end of the drive member is provided with a drive end 801, which is connected to the slide 7 through a hinge, a universal joint or other hinged mechanism, so that the linear motion of the drive end 801 can be converted into the movement of the slide 7 in the slide groove 503. In this embodiment, by adding a linear drive member 8, a precise and controllable driving method is provided for the powder scraping member 6, thereby improving the automation degree and work efficiency of the powder scraping operation. At the same time, the hinged connection between the linear drive member 8 and the slide 7 enables the slide 7 to adapt to the complex shape of the inner wall of the powder blocking member 5 and the length change of the slide groove 503, further improving the powder scraping effect and the stability of equipment operation.

[0054] Furthermore, the movable top plate 602 is in the form of a plate.

[0055] In this embodiment, the movable top plate 602 is designed as a plate-type structure, that is, it has a flat, large-area surface that matches the shape of the inner wall of the powder blocking member 5 and is used to directly contact and scrape off the powder adhering to the inner wall of the powder blocking member 5.

[0056] Furthermore, the powder blocking member 5 has a collecting groove 506 , and the collecting groove 506 is located at one side of the lower blocking portion 505 , and the lower blocking portion 505 is inclined toward the inside of the collecting groove 506 .

[0057] In this embodiment, the initial position of the movable top plate 602 is set at the upper block 504. When cleaning operation is required, under the drive of the linear drive member 8, the movable top plate 602 scrapes and cleans the upper block 504, the middle of the channel 501 and the lower block 505 in turn, and finally scrapes the powder into the collection groove 506 on the side of the lower block 505.

[0059] In this embodiment, the powder spray gun 3 can be driven to move up and down by the rotation of the screw rod 11, thereby improving stability.

[0060] Furthermore, it also includes:

[0061] The turbine 12 is arranged at one end of the screw rod 11.

[0062] The worm 13 is meshed with the turbine 12, and the worm 13 has a rod portion, which is rotatably arranged on the processing seat 9.
