[0051] The present embodiment provides a uniform feeding system, comprising: a conveying mechanism 1, an adjusting mechanism 2, a detecting mechanism 3 and a control module; the conveying mechanism 1, the adjusting mechanism 2 and the detecting mechanism 3 are all electrically connected to the control module; the conveying mechanism 1 has a conveying channel for conveying powder to a material demand location, the adjusting mechanism 2 is arranged on the conveying channel, and the detecting mechanism 3 is arranged at the discharge end of the conveying channel; the detecting mechanism 3 is used to detect the height of the powder at the material demand location, and the control module controls the speed at which the conveying mechanism 1 conveys the powder through the conveying channel, and controls the adjusting mechanism 2 to adjust the height of the powder on the conveying channel according to the detection information of the detecting mechanism 3.

[0052] In this embodiment, the height of the powder at the material demand location is detected by the detection mechanism 3, and the detection information is fed back to the control module. The control module compares the detection information with the preset powder height value at the material demand location. When it is lower than the preset value, the control module controls the conveying mechanism 1 to increase the speed of conveying the powder through the conveying channel, and controls the regulating mechanism 2 to increase the height of the powder on the conveying channel, so as to increase the feeding amount. When it is higher than the preset value, the control module controls the conveying mechanism 1 to reduce the speed of conveying the powder through the conveying channel, and controls the regulating mechanism 2 to reduce the height of the powder on the conveying channel, so as to reduce the feeding amount. Since the speed of conveying the powder through the conveying channel and the height of the powder on the conveying channel are automatically adjusted together, the feeding demand can be quickly met, the production efficiency can be improved, and the production demand can be met.

It should be noted that the linear drive can be driven vertically up and down to drive the material blocking member to move vertically up and down, and the linear drive can also be driven in a direction inclined relative to the vertical surface toward the conveying direction of the conveying channel, driving the material blocking member to move up and down in a direction inclined relative to the vertical surface toward the conveying direction of the conveying channel. Specifically, a suitable method can be selected according to different materials to improve applicability.

[0054] In this embodiment, positioning blocks 16 are provided at both ends of the fixed plate 15, and positioning grooves are provided on the positioning blocks 16. The conveying baffles 43 on both sides of the conveying channel have convex edges, and the positioning grooves are clamped with the convex edges.

Before fixing, the position of the fixed plate 15 can be adjusted on the convex edge along the length direction of the conveying channel, and then fixed. The position of the fixed plate 15 along the conveying direction of the conveying channel is adjustable, so that the position of the adjustment mechanism 2 can be adjusted, thereby improving applicability.

[0055] In this embodiment, the linear drive can be an electric push rod 17, or a cylinder, or a telescopic motor or a linear module 19, and the material blocking member can be a material blocking plate 18 or a material blocking roller, as long as it meets the requirements.

[0056] However, the present embodiment is not limited thereto, and the linear drive may be replaced by a rotary drive, which drives the material blocking member to rotate so that the material blocking member is moved closer to or farther away from the conveying surface of the conveying channel, which also has an adjustment effect.
