[0002] A feeder is a mechanical device used to evenly and continuously convey materials to the next device. Its main function is to ensure that materials can be conveyed at a stable speed and uniform flow rate, avoiding affecting the production process due to material blockage or material cut-off. A feeder capable of feeding materials at a constant speed is particularly important because it can significantly improve the efficiency and stability of the production line and ensure the smooth progress of subsequent processes. In addition, uniform feeding can also prevent the equipment from being overloaded or damaged due to uneven load, extend the service life of the equipment, and reduce the maintenance cost. Therefore, using a feeder capable of feeding materials at a constant speed is the key to ensuring efficient, safe, and stable production in industrial production.

[0003] Traditional feeders mainly convey materials from one position to another by means of vibration, gravity, or mechanical conveying. Its working principle usually involves a hopper filled with materials, and the materials gradually enter the feeding device under the action of gravity. The vibrating feeder makes the materials move forward on the inclined plane through the periodic vibration generated by the vibrating motor or eccentric block; the belt feeder uses the motor to drive the belt to continuously convey the materials to the next device; the screw feeder pushes the materials forward through the rotating screw blades. These mechanical devices can be adjusted according to the set speed and flow rate to achieve uniform and continuous material conveying and ensure the smooth progress of the production process.

[0004] For traditional feeders, affected by the belt speed and the state of material accumulation, it is difficult to accurately control the conveying volume, resulting in uneven feeding and making the downstream equipment unable to operate continuously and stably, thus affecting the overall efficiency of the production line.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Referring to Figure 1 - Figure 4 , an embodiment provided by the present utility model: a feeder capable of feeding at a uniform speed, including a blanking bin 1. A sliding plate 2 is fixedly connected to the outer wall of the blanking bin 1. A motor 3 is fixedly connected to the inside of the sliding plate 2. The output end of the motor 3 is fixedly connected to a rotating shaft 6. A concave wheel 4 is fixedly connected to the outer wall of the rotating shaft 6. A transmission belt 5 is arranged on the outer wall of the concave wheel 4. An arc-shaped toothed plate 7 is fixedly connected to the outer wall of the rotating shaft 6. A double-sided rack 8 is slidably connected to the inside of the sliding plate 2. The arc-shaped toothed plate 7 meshes with the double-sided rack 8. One end of the double-sided rack 8 is fixedly connected to a feeding bin 9. A blanking plate 10 is fixedly connected to the bottom of the blanking bin 1. The outer wall of the feeding bin 9 is slidably connected to the inside of the blanking plate 10. A hinge 11 is fixedly connected to the bottom of the feeding bin 9. A sealing assembly is arranged on the outer wall of the hinge 11. The sealing assembly is used for sealing the bottom of the feeding bin 9. The sealing assembly includes a first baffle 12. One side of the outer wall of the first baffle 12 is fixedly connected to the outer wall of the hinge 11. A sealing plate 13 is fixedly connected to the upper surface of the first baffle 12. The outer wall of the sealing plate 13 is slidably connected to the inner wall of the feeding bin 9.

[0026] Specifically, first, the material is sent above the sealing plate 13 inside the blanking bin 1, and then slides down to the inside of the feeding bin 9 through the inclined plane on the inner wall of the blanking bin 1. Then, the motor 3 is started, and the rotating shaft 6 is driven to rotate through the output end of the motor 3. The concave wheel 4 is driven to rotate inside the sliding plate 2 through the rotating shaft 6. Then, the two concave wheels 4 and the rotating shaft 6 on both sides are driven to rotate synchronously through the transmission belt 5. Then, the two arc-shaped toothed plates 7 on both sides are driven to rotate synchronously. Due to the meshing relationship between the arc-shaped toothed plate 7 and the double-sided rack 8, the double-sided rack 8 reciprocates inside the sliding plate 2, thereby driving the feeding bin 9 to reciprocate inside the blanking plate 10. Then, the movement of the feeding bin 9 drives the first baffle 12 and the sealing plate 13 to move together. When the feeding bin 9 moves to one end of the blanking plate 10, since there is no support at the bottom, the first baffle 12 rotates around the hinge 11 as the center, thereby opening the bottom of the feeding bin 9, and the material falls above the conveyor belt 23 for transportation. When pulling back, the first baffle 12 and the sealing plate 13 are reset through the hinge 11 to re-seal the bottom of the feeding bin 9, and continuous quantitative feeding is carried out to make the feeding more uniform.

[0027] Referring to Figure 1 and Figure 5, a worm 14 is fixedly connected inside the arc-shaped tooth plate 7, a worm gear 15 is rotatably connected to the inner wall of the sliding plate 2, the worm 14 meshes with the worm gear 15, a rotating rod 16 is fixedly connected inside the worm gear 15, one end of the rotating rod 16 is fixedly connected with a driving wheel 18, a driven wheel 19 is rotatably connected inside the feeding bin 1, the driving wheel 18 meshes with the driven wheel 19, a bearing 17 is fixedly connected to the outer wall of the rotating rod 16, the outer wall of the bearing 17 is fixedly connected inside the feeding bin 1, a stirring blade 20 is fixedly connected to the outer wall of the rotating rod 16, the outer wall of the stirring blade 20 is rotatably connected inside the feeding bin 1, a second baffle 21 is fixedly connected to the outer wall of the feeding bin 1, a support frame 22 is fixedly connected to the lower surface of the second baffle 21, and a conveyor belt 23 is arranged inside the support frame 22;

[0028] Specifically, when the arc-shaped tooth plate 7 rotates, it will drive the worm 14 to rotate together. Due to the meshing of the worm 14 and the worm gear 15, the worm gear 15 drives the rotating rod 16 to rotate with the rotation of the worm 14, so as to drive the stirring blade 20 and the driving wheel 18 to rotate in cooperation with the bearing 17. Due to the meshing of the driving wheel 18 and the driven wheel 19, the rotating rods 16 on both sides rotate synchronously, so as to drive the stirring blades 20 on both sides to rotate synchronously at the feeding port at the bottom of the feeding bin 1, preventing blockage.

[0029] Working principle: When a feeder that can feed materials at a constant speed is needed, first place the materials above the sealing plate 13 in the feeding bin 1. The materials slide down along the inclined plane into the feeding bin 9. Start the motor 3, and its power is transmitted to the cam 4 through the rotating shaft 6 and rotates inside the sliding plate 2. The transmission belt 5 drives the cams 4 and the rotating shafts 6 on both sides synchronously, so as to make the arc-shaped tooth plate 7 rotate synchronously. The arc-shaped tooth plate 7 meshes with the double-sided rack 8, and the double-sided rack 8 reciprocates inside the sliding plate 2, driving the feeding bin 9 to reciprocate inside the feeding plate 10. When the feeding bin 9 moves, it drives the first baffle 12 and the sealing plate 13 to move. When the feeding bin 9 moves to one end of the feeding plate 10, the first baffle 12 rotates around the hinge 11 as the axis, opening the bottom of the feeding bin 9, and the materials fall onto the conveyor belt 23. When pulling back, the first baffle 12 and the sealing plate 13 reset, sealing the bottom of the feeding bin 9, realizing continuous quantitative feeding and ensuring uniform feeding;

[0030] In addition, the rotation of the arc-shaped tooth plate 7 drives the worm 14, which meshes with the worm gear 15. The worm gear 15 drives the rotating rod 16 to rotate. The bearing 17 supports the rotating rod 16, driving the stirring blade 20 and the driving wheel 18 to rotate. The driving wheel 18 meshes with the driven wheel 19, making the rotating rods 16 on both sides rotate synchronously, and the stirring blades 20 rotate synchronously at the feeding port at the bottom of the feeding bin 1, preventing the materials from being blocked.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
