Description

Technical Field

[0001] The utility model relates to the technical field of powder conveying equipment, in particular to an anti-blocking discharging structure for powder conveying and a feeder. Background Technique

[0002] A feeder is a commonly used material conveying equipment. Common feeders include electromagnetic vibrating feeders, bar vibrating feeders, and screw feeders. When working, it can convey materials from the feed inlet to the discharge outlet. However, when transporting powdery materials, due to the high cohesion between powdery materials, during powder conveying, the discharge end often gets blocked due to the accumulation of powder. Currently, generally, the screw feeders on the market are not equipped with dredging structures. Therefore, when the discharge outlet gets blocked, it is necessary to stop the machine and then manually dredge it, which affects the transportation efficiency. At the same time, the powder will be polluted during the dredging process, resulting in powder waste. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti-blocking discharging structure for powder conveying and a feeder to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0026] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0027] In addition, for a better illustration of the present application, numerous specific details are provided in the following specific embodiments. Those skilled in the art should understand that the present application can be implemented without certain specific details. In some instances, methods, means, and components well-known to those skilled in the art are not described in detail to highlight the gist of the present application.

[0028] Please refer to Figures 1-6 , in an embodiment of the present utility model, an anti-blocking discharging structure for powder conveying and a feeder include:

[0029] A base 1, on which a conveying cylinder 3 is fixedly arranged, and an inlet hopper 2 and a discharge pipe 8 are fixedly arranged on the conveying cylinder 3;

[0030] A conveying structure is arranged in the conveying cylinder 3, and the conveying structure cooperates with a stirring structure arranged in the inlet hopper 2 to be able to convey the powder in the inlet hopper 2 to the discharge pipe 8;

[0031] The conveying structure includes a spiral auger 5 rotatably installed in the conveying cylinder 3, and one end of the spiral auger 5 penetrates through the conveying cylinder 3 and is fixedly connected to the output shaft of a motor fixedly installed on the base 1;

[0032] The stirring structure includes a stirring shaft 4 rotatably installed in the inlet hopper 2, and one end of the stirring shaft 4 penetrates through the inlet hopper 2 and is connected to the spiral auger 5 through a belt;

[0033] Preferably, please refer to Figure 2 , multiple groups of stirring rollers are equidistantly arranged along the axial direction of the above-mentioned stirring shaft 4. When transporting powder, start the motor, and the continuously rotating motor output shaft in the same direction will drive the spiral auger 5 to rotate continuously in the same direction, transporting the powder entering the conveying cylinder 3 from the inlet hopper 2 to the discharge pipe 8. Then, the powder will fall into a receiving bucket (not shown in the figure) below the discharge pipe 8 under the action of gravity. And during the process of powder conveying, the continuously rotating spiral auger 5 in the same direction will drive the stirring shaft 4 to rotate continuously in the same direction under the action of the belt. During the rotation process, the stirring rods on the stirring shaft 4 can disperse and convey the powder in the inlet hopper 2, so that the powder in the inlet hopper 2 will not accumulate, thereby enabling the powder to normally enter the conveying cylinder 3 for transportation.

[0034] Furthermore, please refer to Figures 1-6, an anti-clogging discharging structure for powder conveying and a feeder, further comprising an anti-clogging structure. The anti-clogging structure is arranged on the discharging pipe 8 and includes a driving structure and a lifting structure. The driving structure is connected to the conveying structure and includes a driving member rotatably installed on the discharging pipe 8. The lifting structure includes a loosening member slidably arranged on the discharging pipe 8, and the loosening member is connected to an elastic structure fixedly arranged on the discharging pipe 8. When the conveying structure operates, the loosening member will reciprocally lift along the axial direction of the discharging pipe 8 under the cooperation of the driving member and the elastic structure, so as to dredge the powder accumulated at the discharging pipe 8.

[0035] The driving member includes a collar 11 rotatably installed on the outer wall of the discharging pipe 8, and a first toothed structure 1101 is equidistantly arranged in a circle along the circumferential direction at one end of the collar 11 away from the conveying cylinder 3.

[0036] The driving structure further includes a linkage gear 7 rotatably installed on the conveying cylinder 3. The linkage gear 7 meshes with a toothed ring 12 fixedly arranged on the outer wall of the collar 11, and the linkage gear 7 is connected to the spiral auger 5 through a bevel gear set 6.

[0037] The bevel gear set 6 includes a first bevel gear and a second bevel gear. The first bevel gear is coaxially and fixedly connected to the spiral auger 5, and the second bevel gear is coaxially and fixedly connected to the linkage gear 7.

[0038] Specifically, please refer to Figure 1 、 Figure 2 、 Figure 3 , combined with the above, when the spiral auger 5 is driven by the motor to continuously rotate in the same direction, the meshing transmission state of the first bevel gear and the second bevel gear will drive the linkage gear 7 to continuously rotate in the same direction. Subsequently, after the rotating linkage gear 7 enters the meshing transmission state with the toothed ring 12, it will drive the collar 11 to rotate around the axis of the discharging pipe 8. And when the collar 11 rotates, the first toothed structure 1101 at its end will cooperate with the loosening member, and can drive the loosening member to reciprocally lift along the axial direction of the discharging pipe 8, so as to be able to disperse and convey the powder accumulated inside the discharging pipe 8, so that the powder can fall normally.

[0039] Furthermore, please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6, the loosening member includes a lifting sleeve 10 slidably connected to the discharge pipe 8. One end of the lifting sleeve 10 facing the collar 11 is provided with a second toothed structure 1001 that cooperates with the first toothed structure 1101 at equal intervals along its circumferential direction. A fixing ring 1002 is provided on the other side, and a loosening block 15 and a loosening rod 16 are provided on the inner wall of the lifting sleeve 10;

[0040] The elastic structure includes a mounting ring 9 fixedly installed on the discharge pipe 8. A plurality of guide rods 13 are provided at equal intervals along the circumferential direction on one side of the mounting ring 9 facing the lifting sleeve 10. A spring 14 is slidably arranged on each group of guide rods 13. One end of the spring 14 abuts against the mounting ring 9, and the other end abuts against the fixing ring 1002;

[0041] Preferably, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , the above-mentioned loosening rods 16 are provided in eight groups at equal intervals along the circumferential direction of the lifting sleeve 10. The eight groups of loosening rods 16 are respectively slidably arranged in eight through grooves 801 provided at equal intervals along the circumferential direction of the discharge pipe 8. With the cooperation of the through grooves 801 and the loosening rods 16, the lifting sleeve 10 can only lift and lower along the axial direction of the discharge pipe 8. And the above-mentioned loosening block 15 is fixedly connected to two groups of oppositely arranged loosening rods 16, that is, the axis of the loosening block 15 is just one of the radii of the discharge pipe 8. In particular, the loosening block 15 is arranged in a "diamond structure". When the lifting sleeve 10 is lifted and lowered, the diamond-structured loosening block 15 can well break the accumulated powder. Subsequently, with the cooperation of the remaining loosening rods 16, the lifting and lowering sleeve 10 can disperse the accumulated powder so that the discharge pipe 8 can discharge smoothly;

[0042] Specifically, please refer to Figure 1 , Figure 2 , Figure 4, in the initial state, the above-mentioned spring 14 is in a compressed state. At this time, the first tooth-shaped structure 1101 and the second tooth-shaped structure 1001 are in a meshed state. After starting the motor, the continuously rotating screw auger 5 will drive the collar 11 to rotate self-reliantly under the cooperation of the bevel gear set 6, the linkage gear 7 and the toothed ring 12. At this time, the tooth walls of the first tooth-shaped structure 1101 and the second tooth-shaped structure 1001 come into contact and extrusion, which will force the second tooth-shaped structure 1001 to drive the lifting sleeve 10 to descend along the axial direction of the discharge pipe 8, and then further compress the spring 14. After the lifting sleeve 10 descends to the lowest point, the first tooth-shaped structure 1101 and the second tooth-shaped structure 1001 are separated. Subsequently, the elastic potential energy released by the spring 14 will push the lifting sleeve 10 to rise, so that the first tooth-shaped structure 1101 and the second tooth-shaped structure 1001 are restored to meshed rotation again. Subsequently, the above process is continued. When the screw auger 5 transports the powder material, the lifting sleeve 10 will continuously execute the lifting process, thereby driving the loosening rod 16 and the loosening block 15 to disperse the powder material in the discharge pipe 8, so that the discharge pipe 8 will not be blocked due to the accumulation of powder material, and then the discharge pipe 8 can discharge smoothly, improving the overall transportation efficiency.
