[0001] The utility model relates to the technical field of powder feeders, in particular to a powder feeder capable of preventing powder congestion. Background Art

[0002] A powder feeder is a device used to transport powdered materials. It is widely used in thermal spraying, laser cladding, 3D printing and other fields. Its main function is to accurately deliver powdered materials into the processing area to achieve continuous, uniform and stable powder transportation. Powder feeders play an important role in modern manufacturing. They not only improve production efficiency, but also ensure the consistency and stability of product quality.

[0003] A powder feeder is required during laser cladding to achieve the effect of conveying metal powder. Currently available powder feeders can achieve continuous, uniform and stable powder conveying.

[0004] However, the currently available powder feeders cannot dry the metal powder, resulting in that when the metal powder has a certain humidity due to weather problems, the slightly damp metal powder is prone to agglomeration during the transportation process, thereby reducing its fluidity, causing the continuity and uniformity of powder feeding to deteriorate, and ultimately easily causing the powder discharge pipe to be blocked, causing the powder discharge to stop, seriously affecting the powder discharge efficiency and failing to meet production needs. Therefore, a powder feeder that prevents powder congestion is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a powder feeder that prevents powder congestion, which solves the problem that the metal powder cannot be dried, resulting in the phenomenon that when the metal powder has a certain humidity due to weather problems, the slightly damp metal powder is prone to agglomeration during the transportation process, thereby reducing its fluidity, making the continuity and uniformity of powder feeding worse, and ultimately easily causing the powder outlet pipe to be blocked, causing the powder outlet to stop, seriously affecting the powder outlet efficiency, and failing to meet production needs.

[0006] To achieve the above object, the utility model provides the following technical solutions: a powder feeder for preventing powder congestion, comprising a powder feeder body and an upper cover, wherein an anti-blocking powder feeding structure is arranged outside the powder feeder body;

[0007] The anti-clogging powder feeding structure includes heating tubes fixedly connected to the left and right sides of the inner wall of the upper cover, fans are fixedly connected to the left and right sides of the top of the upper cover, filters are fixedly connected to the top and bottom of the fan, a first motor is fixedly installed in the middle of the top of the upper cover, the output shaft of the first motor is fixedly connected to the first rotating shaft, the outer surface of the first rotating shaft is fixedly connected to the first stirring blade, the left side of the powder feeder body is fixedly connected to the second motor, the output shaft of the second motor is fixedly connected to the second rotating shaft, and the outer surface of the second rotating shaft is fixedly connected to the second stirring blade.

[0008] Furthermore, a strip-shaped feed port is provided on the front of the upper cover, a sealing cover plate is hinged on the front of the upper cover, and a magnetic frame is fixedly connected to the back of the sealing cover plate.

[0009] Furthermore, a sliding sleeve is fixedly connected to the front of the upper cover, and a positioning sleeve is fixedly connected to the front of the sealing cover plate.

[0010] Furthermore, a latch is slidably connected inside the sliding sleeve, and the latch is plugged into the positioning sleeve.

[0011] Furthermore, the first motor and the second motor have the same outer diameter and the same speed.

[0012] Furthermore, threaded holes are provided at the upper end of the powder feeder body and the lower end of the upper cover, and positioning screws are connected to the internal threads of the threaded holes.

[0014] Compared with the prior art, the utility model provides a powder feeder that prevents powder congestion, which has the following beneficial effects:

[0015] The powder feeder with anti-powder congestion achieves the effects of drying and accelerating the conveying speed by setting an anti-clogging powder feeding structure, thereby reducing the humidity of the metal powder to the greatest extent, avoiding the agglomeration of the metal powder, and then improving its fluidity, ensuring the continuity and uniformity of powder feeding, avoiding the blockage of the discharge pipe, and then improving the powder discharge efficiency. Before conveying the metal powder, the staff first needs to start the heating tube and the fan, and use the current to pass through the heating tube to make the heating tube generate heat, so as to heat the air. At this time, the fan can continuously blow the hot air to the metal powder, thereby reducing its humidity. At this time, starting the first motor and the second motor can finally drive the first stirring blade and the second stirring blade to rotate through the cooperation of the first rotating shaft and the second rotating shaft, and then respectively stir and turn the metal powder located in the upper and lower sections of the powder feeder body, so that it is fully in contact with the hot air and accelerates the evaporation rate of water.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1In this embodiment, a powder feeder for preventing powder congestion comprises a powder feeder body 1 and an upper cover 2, and an anti-blocking powder feeding structure is arranged outside the powder feeder body 1;

[0024] The anti-clogging powder feeding structure includes a heating tube 3 fixedly connected to the left and right sides of the inner wall of the upper cover 2, a fan 4 is fixedly connected to the left and right sides of the top of the upper cover 2, and a filter screen 5 is fixedly connected to the top and bottom of the fan 4. A first motor 6 is fixedly installed in the middle of the top of the upper cover 2, and the output shaft of the first motor 6 is fixedly connected to the first rotating shaft 7, and the outer surface of the first rotating shaft 7 is fixedly connected to the first stirring blade 8. The left side of the powder feeder body 1 is fixedly connected to the second motor 9, and the output shaft of the second motor 9 is fixedly connected to the second rotating shaft 10, and the outer surface of the second rotating shaft 10 is fixedly connected to the second stirring blade 11. Before conveying metal powder, the staff first needs to start the heating tube 3 and the fan 4, and use electric current to pass through the heating tube 3 to generate heat in the heating tube 3, so as to heat up the air. At this time, the fan 4 can continuously blow hot air to the metal powder, thereby reducing its humidity.

[0025] At this time, starting the first motor 6 and the second motor 9 can ultimately drive the first stirring blade 8 and the second stirring blade 11 to rotate through the cooperation of the first rotating shaft 7 and the second rotating shaft 10, thereby stirring and turning the metal powder located in the upper and lower sections of the powder feeder body 1 respectively, so that it is fully in contact with the hot air, thereby accelerating the evaporation rate of water.

[0026] In addition, during transportation, the rotating first rotating shaft 7 and the first stirring blade 8 can accelerate the speed of the metal flowing downward, thereby improving the transportation efficiency.

[0027] The first motor 6 and the second motor 9 have the same outer diameter and the same speed. A discharge pipe 20 is fixedly connected to the bottom of the powder feeder body 1, and the discharge pipe 20 is connected to the powder feeding pipe.

[0028] It should be noted that before conveying the metal powder, since the valve of the powder feeding pipe is not opened, when the first stirring blade 8 and the second stirring blade 11 rotate, the metal powder will not be fed into the molten pool but will still remain inside the powder feeder body 1.

[0029] Embodiment 2:

[0030] See also Figure 2-4On the basis of the first embodiment, a strip-shaped feed port 12 is provided on the front of the upper cover 2, a sealing cover plate 13 is hinged on the front of the upper cover 2, a magnetic frame 17 is fixedly connected to the back of the sealing cover plate 13, a sliding sleeve 14 is fixedly connected to the front of the upper cover 2, a positioning sleeve 16 is fixedly connected to the front of the sealing cover plate 13, a latch 15 is slidably connected inside the sliding sleeve 14, and the latch 15 is plugged into the positioning sleeve 16. Through the cooperation of the sealing cover plate 13, the sliding sleeve 14, the positioning sleeve 16, the latch 15 and the magnetic frame 17, the sealing cover plate 13 can be firmly fixed near the feed port 12, thereby enhancing its sealing performance and preventing metal powder from flying out.

[0031] When feeding is needed, the staff only needs to pull the latch 15 upwards to release the connection between the latch 15 and the positioning sleeve 16. At this time, the sealing cover plate 13 is pulled outward with force to expose the feed port 12, so that the staff can pour metal powder into the powder feeder body 1 for convenient feeding.

[0032] In addition, a threaded hole 18 is provided at the upper end of the powder feeder body 1 and the lower end of the upper cover 2, and a positioning screw 19 is connected to the internal thread of the threaded hole 18. By setting the threaded hole 18 and the positioning screw 19, the effect of easy disassembly and assembly and easy cleaning is achieved. When it is necessary to clean the powder feeder body 1 and the upper cover 2, the staff only needs to remove the positioning screw 19 from the inside of the threaded hole 18 with a screwdriver to release the connection between the powder feeder body 1 and the upper cover 2, thereby separating the two and then cleaning the interior.

[0033] The working principle of the above embodiment is:

[0034] Before conveying the metal powder, the staff first needs to start the heating tube 3 and the fan 4, and use electric current to pass through the heating tube 3 to generate heat in the heating tube 3, so as to heat up the air. At this time, the fan 4 can continuously blow hot air to the metal powder, thereby reducing its humidity. At this time, the first motor 6 and the second motor 9 are started, and the first rotating shaft 7 and the second rotating shaft 10 can be coordinated to finally drive the first stirring blade 8 and the second stirring blade 11 to rotate, thereby stirring and turning the metal powder located in the upper and lower sections of the powder feeder body 1 respectively, so that it is fully in contact with the hot air and accelerates the evaporation rate of water. In addition, during transportation, the rotating first rotating shaft 7 and the first stirring blade 8 can accelerate the downward flow of metal, thereby improving the transportation efficiency.

[0035] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role, and the existing public power connection technology is not described in detail in the text.
