Description

Technical Field

[0001] The utility model relates to the technical field of feeders, in particular to a conveying auger used for an ultrafine powder feeder. Background Art

[0002] Twin screw volumetric feeder is suitable for various powders, granules, flake powders, microparticles and fibers with poor fluidity, and can ensure continuous and uniform feeding and conveying of materials.

[0003] After searching, a twin-screw volumetric feeder (CN211393115) includes a base, a fixed seat is fixedly installed on the top of the base, a conveying motor is fixedly installed on the left side of the fixed seat, a conveying pipe is fixedly installed on the right side of the fixed seat, a material guide pipe is fixedly installed on the top of the conveying pipe, and a feeder body is fixedly installed on the top of the material guide pipe. The twin-screw volumetric feeder is installed with a rotating rod extending into the feeder body and a mixing plate installed on the rotating rod. The power motor can drive the mixing plate to mix and stir the materials inside the feeder body through the rotating rod. By installing a reducer on the rotating rod, the material guide auger can slowly discharge the materials, and the rotating rod drives the mixing plate to quickly mix the materials, so that the materials can be quickly mixed and evenly mixed, thereby achieving the purpose of quickly mixing multiple materials.

[0004] However, since the conveying auger of an ordinary feeder can only be used for conveying, it is unable to screen the ultrafine powder when conveying it, so that the ultrafine powder needs to be screened again during and after conveying, resulting in low efficiency. In view of this, we propose a conveying auger for an ultrafine powder feeder. Utility Model Content

[0027] Embodiment 2

[0028] See also Figure 1-Figure 5On the basis of the first embodiment, the utility model provides a technical solution: preferably, a slide groove 9 is provided on the outer arc surface of the support plate 7, and a vibration mechanism 10 is arranged in the slide groove 9. The vibration mechanism 10 includes a slide plate 101. In order to ensure that the slide plate 101 can stably move in the vertical direction, the slide groove 9 is provided on the conveying pipe shell 8 to limit the slide plate 101, so that the slide plate 101 is more stable when moving, thereby improving the stability of the entire mechanism. The slide plate 101 is slidably connected to the inner surface of the slide groove 9, and an arc groove 102 is provided on the upper surface of the slide plate 101. The inner surface of the arc groove 102 is slidably connected with a movable plate 103. In order to ensure that the movable plate 103 can slide stably, the movable plate 103 is limited by the arc groove 102, so that the movable plate 103 can be more stably contracted into the arc groove 102 after being subjected to force, and the outer shell of the feeder body 1 is vibrated by the elastic force of the second spring 11. , to prevent the ultrafine powder from sticking to the inner wall of the feeder body 1, one end of the second spring 11 is fixedly connected to the inner surface of the arc groove 102, and the movable plate 103 is fixedly connected to the other end of the second spring 11, the cross-sectional shape of the movable plate 103 is rack-shaped, the outer arc surface of the screening plate 42 is fixedly connected to the inner surface of the slide plate 101, and an annular triangular groove 12 is provided on the outer arc surface of the feeder body 1. In order to ensure that the movable plate 103 can be retracted into the arc groove 102 when passing through the up and down movement of the screening plate 42, the annular triangular groove 12 and the movable plate 103 cooperate with each other, so that the annular triangular groove 12 can squeeze the inclined surface of the movable plate 103, so that the movable plate 103 is retracted into the annular triangular groove 12, and through the elasticity of the second spring 11, the movable plate 103 is bounced toward the feeder body 1, and the surface of the feeder body 1 is vibrated, thereby preventing the ultrafine powder from sticking to the inner surface of the feeder body 1, and the annular triangular groove 12 is slidably connected to the movable plate 103.

[0029] In this embodiment, by providing the slide plate 101, the movable plate 103 and the annular triangular groove 12, when the screening plate 42 moves downward, the annular triangular groove 12 can squeeze the inclined surface of the movable plate 103, so that the movable plate 103 vibrates the surface of the feeder body 1 through the elasticity of the second spring 11, thereby effectively preventing the ultrafine powder from sticking to the inner wall of the feeder body 1.

[0030] Working principle: when the motor 2 is started and the output shaft drives the conveying dragon 3 to rotate, the bottom of the conveying dragon 3 will squeeze the inclined surface of the conical force-bearing rod 44, so that the conical force-bearing rod 44 drives the screening plate 42 to move downward. When the screening plate 42 moves downward, the first spring 5 will be stretched, and after the conveying dragon 3 is no longer in contact with the conical force-bearing rod 44, the screening plate 42 will move upward through the elastic force of the first spring 5, and the ultrafine powder will shake on the screening net 43 through the curved groove 6, and the qualified ultrafine powder will pass through the screening net 43 When the material enters the conveying pipe shell 8 and the screening plate 42 moves downward, the slide plate 101 is driven to move downward. When the slide plate 101 moves downward, the movable plate 103 is driven to move downward. The annular triangular groove 12 squeezes the inclined surface of the movable plate 103, so that the movable plate 103 contracts into the arc groove 102. When the teeth of the movable plate 103 are parallel to the annular triangular groove 12, the elasticity of the second spring 11 bounces the movable plate 103 toward the surface of the feeder body 1, causing vibration to the surface of the feeder body 1.
