Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a powder feeding device. Background Art

[0002] At present, when adding powder to the equipment, since the feed port of the equipment is often set at the top of the equipment, the staff often need to transport the powder to a high place for adding. For example, the Chinese patent with publication number CN213140276U discloses a spiral feeder for preventing powder dust. The powder is placed into the feed port, enters the first pipe through the feed port, and enters the outer shell from the first pipe. A funnel shape is used to reduce the fly ash of the powder. The powder enters the propeller inside the outer shell, and the starting motor drives the rotating rod to rotate. The rotating rod drives the propeller to rotate, and the propeller drives the powder to be transported upward, and finally the powder is discharged from the discharge port, thereby realizing the feeding process of the powder. However, since the powder particles are very fine and easy to be raised, when the staff cuts the powder bag and puts it into the feed port of the equipment, the powder will quickly spread in the air, which will not only pollute the working environment and cause damage to the health of the staff and induce respiratory diseases, but also these dusts will adhere to the equipment for a long time and may affect the normal operation of the equipment.

[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-3 As shown, the embodiment of the utility model proposes a powder feeding device, including a feeding equipment 1, a feeding rod 3 and a cutting assembly. The feeding port on the top of the feeding equipment 1 is fixedly connected to a feeding box 2, the top of the feeding box 2 is open, and the feeding box 2 is provided with a closing assembly for opening or closing the opening of the feeding box 2. There are two feeding rods 3, and the two feeding rods 3 are rotatably arranged on both sides of the feeding equipment 1. One side of one of the feeding rods 3 is provided with a first motor 4 to drive it to rotate. The two feeding rods 3 are connected to a cross bar 5 at one end away from the feeding equipment 1, and multiple pull ropes 6 are convoluted on the cross bar 5. Each pull rope 6 is provided with a clamping mechanism 7 for clamping a bag of powder at the end away from the cross bar 5. The feeding rod 3 is also provided with an adjusting assembly for driving the pull rope 6 to lower or lift out the feeding box 2. The cutting assembly is arranged in the feeding box 2, and the cutting assembly is used to cut the bag of powder. Specifically, the feeding equipment 1 is an existing production device using powder as raw material, and the clamping mechanism 7 is a pneumatic clamp or a spring clamp, which can be selected from the existing technology. The purpose is to clamp and fix the corners of the material bag. When loading, one side of the powder bag is tightened and fixed with the clamping structure. Preferably, there are two first motors 4, which are respectively connected to the two loading rods 3 on both sides of the feeding equipment 1. The first motor 4 can be fixed to the ground or fixed to the feeding equipment 1 or the feeding box 2 through a frame. Start the first motor 4, which drives the feeding rod 3 to rotate through the reducer, so that the two feeding rods 3 are in a vertical state. At this time, the material bag is directly above the feeding box 2, and then start the adjustment component. The adjustment component causes the pull rope 6 to drop until the material bag enters the feeding box 2, and then start the closing component. The closing component closes the opening at the top of the feeding box 2, and then the cutting component is started. The cutting component cuts the material bag so that the powder in the material bag is put into the feeding equipment 1. Since the process of opening the material bag is located in the feeding box 2 and the opening at the top of the feeding box 2 has been closed, the dust generated by the powder will only overflow into the feeding box 2 and will not overflow to the outside, thereby avoiding the pollution of the powder to the surrounding environment and protecting the health of the workers. Preferably, the material bag can be taken out of the feeding box 2 by operating the various components the next time it is needed to feed.

[0020] like Figure 1-3 As shown, the adjustment assembly further includes: a second motor 8, which is fixedly mounted on one of the feeding rods 3. Both ends of the cross bar 5 are rotatably connected to the feeding rod 3, and the output end of the second motor 8 is fixedly connected to the cross bar 5. Specifically, the second motor 8 is mounted on one end of the feeding rod 3 away from the feeding equipment 1. When it is necessary to drive the material bag suspended by the pull rope 6 to be lowered into the feeding box 2, the second motor 8 is started, and the second motor 8 releases the pull rope 6, thereby lowering the horizontal height of the material bag suspended on the pull rope 6 until it enters the feeding box 2.

[0021] Furthermore, each feeding rod 3 is a telescopic rod. Specifically, the telescopic rod is a hydraulic rod, which has two functions. On the one hand, after the cutting assembly cuts the material bag, it can drive the material bag to shake up and down, thereby accelerating the discharge and exhaustion of the powder in the material bag. On the other hand, it can replace the function of the adjustment assembly and make the material bag enter or leave the feeding box 2 by extending and retracting the feeding rod 3.

[0022] like Figure 1 and 3 As shown, further, the cutting assembly includes: a rotating shaft 9, which is horizontally and rotatably arranged in the feeding box 2, and a plurality of cutters 10 are fixedly installed on the rotating shaft 9. The feeding box 2 is also provided with a third motor 11 that drives the rotating shaft 9 to rotate. In this embodiment, the third motor 11 is fixedly installed on the outer wall of the feeding box 2, and the output end of the third motor 11 is fixedly connected to one end of the rotating shaft 9. When the material bag enters the feeding box 2, the closing assembly closes the opening at the top of the feeding box 2, and then starts the third motor 11. The third motor 11 drives the rotating shaft 9 to rotate, causing the cutters 10 on the rotating shaft 9 to cut the bottom end of the material bag, so that the powder in the material bag is discharged and finally enters the feeding device 1. During this process, because the closing assembly has sealed the opening of the feeding box 2, the dust generated when the powder is discharged will not overflow from the feeding box 2, ensuring a clean external working environment. Preferably, the installation direction of the cutting assembly is set as needed, so that the cutter 10 can cut the material bag longitudinally or transversely.

[0023] like Figure 1-3As shown, further, the closing component includes: a closing door 12, the closing door 12 is two pieces, the two closing doors 12 are symmetrically and slidingly arranged on the top of the feeding box 2, a mounting plate 13 is fixedly provided on the side wall of the feeding box 2, a fourth motor 14 is fixedly provided on the mounting plate 13, a first rack 15 is provided at the bottom of one of the closing doors 12, a second rack 16 is slidingly provided on the mounting plate 13, the second rack 16 is fixedly connected to the other closing door 12, a gear 17 is provided on the output end of the fourth motor 14, and the two sides of the gear 17 are respectively engaged with the first rack 15 and the second rack 16. Specifically, the first rack 15 and the second rack 16 are arranged opposite to each other, and the second rack 16 is fixedly connected to one of the closed doors 12 through a connecting piece. When the opening at the top of the feeding box 2 needs to be opened or closed, the fourth motor 14 is started, and the fourth motor 14 drives the gear 17 at its output end to rotate. The gear 17 drives the first rack 15 and the second rack 16 engaged therewith to move horizontally, so that the two closed doors 12 open or close the opening at the top of the feeding box 2.

[0024] like Figure 1-3 As shown, further, rubber strips 18 are provided on opposite sides of the two closed doors 12. When the closed doors 12 close the top opening of the feeding box 2, the drawstring 6 is located between the two closed doors 12. The rubber strips 18 can protect the drawstring 6 while reducing the size of the gap between the two closed doors 12, achieving a better sealing effect.

[0025] like Figure 1 and 3 As shown, further, a guide rod 19 is fixedly provided on one side of one of the closed doors 12 facing the other closed door 12, and a slot is provided on the other closed door 12 for inserting the guide rod 19. One end of the guide rod 19 is slidably connected to the slot, and the guide rod 19 guides the movement of the two closed doors 12, ensuring stability during the movement of the two closed doors 12.

[0026] like Figure 4 As shown, further, the bottom of the feeding box 2 is an arc-shaped structure. Since the bottom of the feeding box 2 is connected to the feeding port at the top of the feeding equipment 1, the connection between the two is set to be an arc-shaped, so that the powder can enter the feeding equipment 1 more quickly and smoothly.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
