Description

Technical Field

[0001] The utility model relates to the technical field of vibrating bowls, in particular to a stepped feeding device for reducing material accumulation. Background Technique

[0002] A vibrating bowl is a feeding device for automatic directional sorting, mainly composed of a hopper, a chassis, a controller, a linear feeder, etc. The vibrating bowl automatically and orderly conveys disordered workpieces to the next process through vibration. Before using the vibrating bowl, a feeding mechanism is required to convey materials into the vibrating bowl.

[0003] A high-stability feeding device for a vibrating bowl mentioned in an existing Chinese patent (authorized announcement number: CN208377801U) transports the materials in the hopper upward. After the materials are transported to the top, they are poured into the guide plate and then led into the vibrating bowl by the guide plate. This feeding device adopts inflow feeding, induced discharging, and a large-capacity hopper with a dense layout. There is almost no backfeeding and digging phenomenon during material lifting, so the ineffective power is small, and the lifting range is wide. It can not only lift general powdery and small granular materials, but also lift materials with relatively large abrasiveness. It has good sealing performance and less environmental pollution.

[0004] When the existing vibrating bowl is in use, a feeding mechanism is required to send materials into the vibrating bowl. However, the inner side of the existing hopper is mostly funnel-shaped and inclined. When transporting irregular materials, friction will occur between the materials and the inner wall of the hopper, which may generate static electricity. The materials with static electricity may adsorb on the funnel wall made of metal material, thus forming accumulation and hindering the flow of other materials. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that materials with static electricity may adsorb on the funnel wall made of metal material, thus forming accumulation and hindering the flow of other materials. The utility model provides a stepped feeding device for reducing material accumulation.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] A stepped feeding device for reducing material accumulation, comprising a frame. At the top of the frame, two groups of support rods are fixedly connected symmetrically front and back. At the top of the support rods, a feeding table is fixedly connected. Inside the feeding table, a conveyor belt is arranged. On the outer side of the conveyor belt, a number of feeding blocks are fixedly connected at equal intervals. At the top of the feeding table, a blanking box is fixedly connected. At the top of the feeding table at the lower end, a feeding hopper is fixedly connected. At the top of the frame, a placing table is fixedly connected. Above the placing table, a conveyor belt is arranged, which is adapted to the discharge port of the blanking box. Above the conveyor belt, a detection device is arranged. On both sides of the top of the frame, a vibration mechanism is arranged. Outside the feeding hopper, a pushing mechanism is arranged.

[0008] By adopting the above technical solution, the material is put into the feeding hopper, and then the conveyor belt is started. The material can be conveyed to the blanking box through the feeding blocks on the conveyor belt. The material entering the blanking box will fall onto the conveyor belt under the action of gravity. The detection device can detect the materials with incorrect placement positions, and then the conveyor belt conveys the materials to the vibrating plate, thus completing the material conveying work. The vibration mechanism can prevent the materials from accumulating inside the feeding hopper, and the pushing mechanism can make the screened materials be fed again.

[0009] Further, the vibration mechanism includes vertical plates fixedly connected symmetrically front and back at the top of the frame. Between the two vertical plates, a connecting plate is fixedly connected. Between the two vertical plates, two rotating rods are fixedly connected at different heights. On the outer side of the rotating rods, striking blocks are fixedly connected symmetrically. When the striking blocks rotate, they are in contact with the outer side of the feeding hopper. On the outer side of the vertical plate, a rotating motor is fixedly connected. The output shaft of the rotating motor penetrates through the vertical plate and is fixedly connected to one side of the rotating rod. The output shaft of the rotating motor is rotatably connected to the vertical plate.

[0010] By adopting the above technical solution, the inside of the feeding hopper vibrates, and the vibration can break the adsorption force between the material and the hopper wall.

[0011] Further, a first belt roller is sleeved on the outer side of the output shaft of the rotating motor. A transmission belt is sleeved on the outer side of the first belt roller. At the end of the transmission belt away from the first belt roller, a second belt roller is sleeved. Inside the second belt roller, a driving rod is fixedly connected. The end of the driving rod close to the vertical plate penetrates through the vertical plate and is fixedly connected to the other side of the rotating rod.

[0012] By adopting the above technical solution, the two striking blocks vibrate the feeding hopper at the same time, which can better break the adhesion between the materials and the adsorption between the materials and the inner wall of the hopper.

[0013] Furthermore, the pushing mechanism includes a bottom plate fixedly connected to one side of the feeding hopper. A fixing plate is fixedly connected to the top of the bottom plate. One end of the fixing plate close to the feeding hopper is fixedly connected with an electric push rod. The output shaft of the electric push rod penetrates through the feeding hopper and is fixedly connected with a pushing plate. The output shaft of the electric push rod is slidably arranged with the feeding hopper.

[0014] By adopting the above technical solution, the movement of the pushing plate makes the material be pushed to a suitable position for re-feeding, thus facilitating the transportation of the material.

[0015] Furthermore, sliders are fixedly connected to both sides of the pushing plate. Chute grooves are formed on both sides of the feeding hopper. The sliders are slidably arranged with the chute grooves.

[0016] By adopting the above technical solution, the pushing plate maintains a correct movement track when moving.

[0017] Furthermore, a screening plate is fixedly connected to one side of the conveyor belt. The side of the screening plate away from the conveyor belt is fixedly connected to the top of the feeding hopper. Oscillating mechanisms are arranged on both sides of the top of the frame. A pushing mechanism is arranged on the outer side of the feeding hopper.

[0018] By adopting the above technical solution, the material screened out re-enters the feeding hopper.

[0019] In summary, the present utility model includes at least one of the following beneficial effects;

[0020] 1. In the present utility model, when the material accumulates inside the feeding hopper, the rotating motor is started to cause oscillation inside the feeding hopper. Through the oscillation, the adsorption force between the material and the hopper wall can be broken, so that the originally accumulated material regains fluidity, ensuring that the material can slide smoothly, reducing the blockage of the hopper outlet due to material accumulation, and ensuring the continuous progress of the production process.

[0021] 2. In the present utility model, when the material placed in the incorrect position falls into the feeding hopper, wait for the feeding to be completed at this time, and then start the electric push rod to move the pushing plate. The movement of the pushing plate makes the material be pushed to a suitable position for re-feeding, thus reducing the inconvenience of manual placement by the staff and further reducing the risk of material extrusion in the feeding hopper.

[0028] The following further elaborates on the present utility model in conjunction with the attached Figures 1-4 drawings.

[0029] An embodiment of the present utility model discloses a stepped feeding device for reducing material accumulation.

[0030] Referring to Figure 1 and Figure 2 , a stepped feeding device for reducing material accumulation includes a frame 1. Two groups of support rods 2 are fixedly connected to the top of the frame 1 symmetrically in the front and rear. The top of the support rods 2 is fixedly connected to a feeding table 3. A transmission belt 4 is arranged inside the feeding table 3. A number of feeding blocks are fixedly connected to the outer side of the transmission belt 4 at equal intervals. A feeding box 5 is fixedly connected to the top of the feeding table 3. A loading hopper 23 is fixedly connected to the top of the feeding table 3 at the lower end. A placing table 6 is fixedly connected to the top of the frame 1. A conveyor belt 7 is arranged above the placing table 6. The conveyor belt 7 is adapted to the discharge port of the feeding box 5. Oscillation mechanisms are arranged on both sides of the top of the frame 1. A material pushing mechanism is arranged outside the loading hopper 23.

[0031] During feeding, first, the material is placed in the loading hopper 23, and then the transmission belt 4 is started. The material can be conveyed to the feeding box 5 through the feeding blocks on the transmission belt 4. The material entering the feeding box 5 will fall on the conveyor belt 7 under the action of gravity. The detection device can detect the materials with incorrect placement positions, and then the conveyor belt 7 conveys the materials to the vibrating plate, thus completing the material conveying work. The oscillation mechanism can oscillate the loading hopper 23 to reduce the accumulation of materials inside the loading hopper 23. The material pushing mechanism can re-feed the screened materials, reducing the manual moving work intensity of the staff.

[0032] Referring to Figure 1 , Figure 2 and Figure 3The oscillation mechanism includes a vertical plate 9 which is symmetrically fixedly connected to the top of the frame 1 in a front-to-back manner, a connecting plate 10 is fixedly connected between the vertical plates 9 on both sides, two rotating rods 12 are fixedly connected at a high and low arrangement between the vertical plates 9 on both sides, and a striking block 13 is symmetrically fixedly connected to the outer side of the rotating rod 12. When the striking block 13 rotates, it conflicts with the outer side of the upper hopper 23. A rotating motor 11 is fixedly connected to the outer side of the vertical plate 9, and the output shaft of the rotating motor 11 passes through the vertical plate 9 and is fixedly connected to one side of the rotating rod 12, and the output shaft of the rotating motor 11 is rotatably connected to the vertical plate 9.

[0033] Among them, a belt roller 1 is sleeved on the outer side of the output shaft of the rotating motor 11, a transmission belt 14 is sleeved on the outer side of the belt roller 1, a belt roller 2 15 is sleeved on the end of the transmission belt 14 away from the belt roller 1, and a driving rod 16 is fixedly connected to the inner side of the belt roller 2 15. The end of the driving rod 16 close to the vertical plate 9 passes through the vertical plate 9 and is fixedly connected to the rotating rod 12 on the other side.

[0034] When the material is accumulated inside the upper hopper 23, the rotating motor 11 is first started to drive the rotating rod 12 to rotate. After the rotating rod 12 rotates, it drives the striking block 13 to strike the upper hopper 23, so that the interior of the upper hopper 23 vibrates. The vibration can break the adsorption force between the material and the hopper wall, so that the originally accumulated material regains fluidity, ensuring that the material can slide down smoothly;

[0035] When the rotating motor 11 rotates, it will drive the belt roller 1 to rotate, and the rotation of the belt roller 1 drives the transmission belt 14 to rotate. The rotation of the transmission belt 14 causes the belt roller 2 15 to rotate, and the rotation of the belt roller 2 15 causes the driving rod 16 to rotate. The rotation of the driving rod 16 causes the rotating rod 12 on the other side to rotate, so that the striking blocks 13 on both sides strike and vibrate the upper hopper 23 at the same time, so that the vibration amplitude inside the hopper is increased, which can better break the adhesion between the materials and the adsorption of the materials and the inner wall of the hopper, and further improve the fluidity of the materials.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The pushing mechanism includes a bottom plate 17 fixedly connected to one side of the upper hopper 23, a fixed plate 18 fixedly connected to the top of the bottom plate 17, an electric push rod 19 fixedly connected to one end of the fixed plate 18 close to the upper hopper 23, an output shaft of the electric push rod 19 passes through the upper hopper 23 and is fixedly connected to a push plate 20, and the output shaft of the electric push rod 19 is slidably arranged with the upper hopper 23.

[0037] The two sides of the push plate 20 are fixedly connected with sliders 22 , and the two sides of the upper hopper 23 are provided with slide grooves 21 , and the sliders 22 and the slide grooves 21 are slidably arranged.

[0038] In addition, one side of the conveyor belt 7 is fixedly connected with a screening plate 8, and the side of the screening plate 8 away from the conveyor belt 7 is fixedly connected with the top of the feeding hopper 23.

[0039] When detecting materials with incorrect placement positions, the detection mechanism will place the materials on the screening plate 8. At this time, the materials will slide down on the screening plate 8 and thus fall into the inner side of the feeding hopper 23;

[0040] When the materials with incorrect placement positions fall into the feeding hopper 23, wait for the feeding to be completed at this time, and then start the electric push rod 19 to move the push plate 20. The movement of the push plate 20 causes the materials to be pushed to a suitable position for re-feeding, thereby reducing the inconvenience of manual placement by the staff and further reducing the risk of material jamming in the feeding hopper 23;

[0041] When the push plate 20 moves, the slider 22 and the chute 21 provide a guiding effect for the push plate 20, so that the push plate 20 maintains the correct movement trajectory when moving.

[0042] Working principle: Put the materials into the feeding hopper 23, and then start the conveyor belt 4. The feeding blocks on the conveyor belt 4 can convey the materials to the blanking box 5. The materials entering the blanking box 5 will fall on the conveyor belt 7 under the action of gravity. The detection device can detect the materials with incorrect placement positions, and then the conveyor belt 7 conveys the materials to the vibrating plate, thus completing the material conveying work. Start the rotating motor 11 to drive the rotating rod 12 to rotate. After the rotating rod 12 rotates, it will drive the striking block 13 to strike the feeding hopper 23, causing the inside of the feeding hopper 23 to vibrate. Through the vibration, the adsorption force between the materials and the hopper wall can be broken, and the originally piled-up materials can regain fluidity.
