Description

Technical Field

[0001] This utility model relates to the field of feeder technology, and in particular to a dust-free feeder. Background Technology

[0002] In many industrial production fields, such as chemical, food, and pharmaceutical industries, the material feeding process is a critical step in the production process. Traditional feeding methods often have many drawbacks, which have adverse effects on the production environment, product quality, and the health of operators. The common feeding method is to manually open the material bag and pour the material into the processing equipment. This operation method exposes the material to the air the moment the bag is opened, which can easily generate a large amount of dust. This dust will not only permeate the production workshop, pollute the working environment, reduce the visibility of the workshop, and affect the operator's vision, but also cause inconvenience to production operations.

[0003] To address the aforementioned issues, some feeding equipment has emerged on the market. However, most of these devices cannot meet the needs of large-scale industrial production, and some still cannot effectively prevent the generation and spread of indiscriminate dust during the feeding process, thus failing to fundamentally improve the environmental problems in the feeding process.

[0004] Therefore, developing a dust-free feeder that is easy to operate and can effectively avoid dust generation and diffusion is of great practical significance. This will provide a clean, safe, and efficient feeding solution for industrial production, improve production efficiency and product quality, and protect the health of operators. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dust-free feeder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dust-free feeder includes a feeding cylinder, a top plate fixed to the top of the feeding cylinder, a hollow column movably connected to a through hole on the surface of the top plate, a rotating plate fixed to the bottom of the hollow column, feeding holes on both the surface of the top plate and the surface of the rotating plate, a placement box fixed to the bottom of the rotating plate, an outlet hole on the bottom of the placement box, a cutting assembly installed on the top of the top plate, and a fan-shaped plate fixed to the inner circumference of the feeding cylinder.

[0008] As a further embodiment of this utility model: a bracket is fixed to the top outer wall of the top plate, a drive motor is fixed to the top outer wall of the bracket, a gear is fixed to the output end of the drive motor, and a gear meshing with the gear is fixed to the outer circumference of the hollow column by a key.

[0009] As a further embodiment of this utility model: the cutting assembly includes an electric telescopic rod and an L-shaped plate. The L-shaped plate is fixed to the top outer wall of the top plate, the electric telescopic rod is fixed to the top outer wall of the L-shaped plate, a movable rod is fixed to the output end of the electric telescopic rod, a connecting plate is fixed to the bottom of the movable rod, and a blade is welded to the top outer wall of the connecting plate.

[0010] As a further improvement of this utility model: an electric telescopic rod is fixed to both outer walls of the placement box, and a clamp is fixed to the output end of the electric telescopic rod.

[0011] As a further improvement of this utility model: an operating platform is fixed to the side of the feeding cylinder, and a support column is welded to the bottom of the operating platform.

[0012] As a further improvement of this utility model, a ladder is fixed to one side of the outer wall of the operating platform.

[0013] As a further improvement of this utility model, a transparent observation window is provided on the side of the feeding cylinder.

[0014] As a further improvement of this utility model, a controller is installed on the side of the feeding cylinder.

[0015] Compared with the prior art, this utility model provides a dust-free feeder with the following features:

[0016] Beneficial effects:

[0017] 1. By controlling the rotation of the hollow column and the rotating plate, the feeding hole on the rotating plate is misaligned with the feeding hole on the top plate. The top plate blocks the feeding hole on the rotating plate, effectively preventing the material bag from being exposed to the external environment and preventing material dust from spreading into the surrounding air, thus reducing pollution to the working environment. During the reset process, the bottom of the box is rotated first to fit against the top of the fan-shaped plate, preventing dust in the operating platform from overflowing through the outlet hole.

[0018] 2. The material bag can be easily climbed to the top of the operating platform via a ladder and placed in the placement box. During the feeding process, the drive motor drives the hollow column and rotating plate to rotate through gear transmission, achieving precise alignment and misalignment of the feeding hole; the electric telescopic rod drives the blade to cut the bottom of the material bag, allowing the material to fall quickly into the bottom of the operating platform; the electric telescopic rod also drives the clamping plate to clamp and fix the material bag to prevent it from falling.

[0019] 3. The transparent observation window on the side of the feed cylinder provides the operator with a clear internal observation view. The operator can observe the falling of the material in the feed cylinder in real time. When no more material falls from the bottom of the discharge hole, it can be accurately determined that the material in the bag has completely fallen, and the next operation can be carried out in time.

[0020] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] A dust-free feeder, such as Figures 1 to 6 As shown, the device includes a feeding cylinder 4, a top plate 5 fixed to the top of the feeding cylinder 4 by bolts, and a hollow column 19 rotatably connected to a through hole on the surface of the top plate 5. A rotating plate 21 is fixed to the bottom of the hollow column 19. Feeding holes 22 are provided on both the surface of the top plate 5 and the surface of the rotating plate 21. A placement box 20 is fixed to the bottom of the rotating plate 21 near the edge of the feeding hole 22 by bolts. An outlet hole 24 is provided at the bottom of the placement box 20. A cutting assembly is installed on the top of the top plate 5, and a fan-shaped plate 8 is fixed to the inner circumference of the feeding cylinder 4 by bolts.

[0030] When feeding is required, the hollow column 19 and the rotating plate 21 are first driven to rotate, so that the feeding hole 22 on the rotating plate 21 and the feeding hole 22 on the top plate 5 are aligned with each other. At this time, the bottom of the placement box 20 moves to the top of the fan-shaped plate 8. Then, the material bag is placed in the placement box 20, and the hollow column 19 and the rotating plate 21 are driven to rotate. In actual operation, the bottom of the rotating plate 21 and the top of the fan-shaped plate 8 can be fixed with flexible pads, which can be made of soft materials such as rubber, thereby improving the sealing between the top of the rotating plate 21 and the bottom of the top plate 5, as well as the bottom of the placement box 20 and the top of the fan-shaped plate 8. When the feeding hole 22 on the rotating plate 21 rotates to the point where it is misaligned with the feeding hole 22 on the top plate 5, the top plate 5 blocks the feeding hole 22 on the rotating plate 21, thereby preventing the material bag from being exposed to the external environment.

[0031] When the bottom of the placement box 20 is rotated to be misaligned with the top of the fan-shaped plate 8, the cutting component is used to cut the bottom of the material bag through the outlet hole 24, so that the material falls into the bottom of the feeding cylinder 4 through the cut opening at the bottom of the material bag and the outlet hole 24. The bottom of the feeding cylinder 4 is equipped with a flange. In the actual production process, the processing equipment, such as the mixing equipment (not shown), can be connected and fixed with the flange at the bottom of the feeding cylinder 4, so that the material enters the processing equipment through the bottom of the feeding cylinder 4 for processing.

[0032] After the material in the bag is fed, the hollow column 19 and the rotating plate 21 are controlled to rotate in opposite directions to reset. Before the feeding hole 22 on the rotating plate 21 and the feeding hole 22 on the top plate 5 are opened to each other, the bottom of the placement box 20 is rotated to fit with the top of the fan-shaped plate 8. Therefore, it can prevent the dust in the feeding cylinder 4 from overflowing through the outlet hole 24 when the two feeding holes 22 are aligned with each other. Then, the bag can be fed into the placement box 20 again to continuously feed the bag.

[0033] The top outer wall of the top plate 5 is fixed with a bracket 12 by bolts, the top outer wall of the bracket 12 is fixed with a drive motor 11 by bolts, the output end of the drive motor 11 is fixed with a gear 18, and the outer circumference of the hollow column 19 is fixed with a gear 13 that meshes with the gear 18 by a key.

[0034] The meshing between the hollow column 19 and the gear 13 enables the drive motor 11 to drive the hollow column 19 and the rotating plate 21 to rotate, so that the rotating plate 21 drives the placement box 20 to rotate during the rotation.

[0035] The cutting assembly includes an electric telescopic rod 6 and an L-shaped plate 10. The L-shaped plate 10 is fixed to the top outer wall of the top plate 5 by bolts. The electric telescopic rod 6 is fixed to the top outer wall of the L-shaped plate 10 by bolts. A movable rod 14 is fixed to the output end of the electric telescopic rod 6, and the movable rod 14 and the hollow column 19 are slidably connected. A connecting plate 15 is fixed to the bottom of the movable rod 14 by screws. A blade 16 is welded to the top outer wall of the connecting plate 15.

[0036] When the outlet hole 24 at the bottom of the placement box 20 rotates to a position directly above the blade 16 under the indirect drive of the drive motor 11, and the moving rod 14 is driven to move vertically by the electric telescopic rod 6, the blade 16 passes through the outlet hole 24 and cuts the bottom of the material bag by squeezing. After the bottom of the material bag is cut, the material falls into the bottom of the upper material cylinder 4 through the outlet hole 24.

[0037] A transparent observation window 9 is provided on the side of the feeding cylinder 4;

[0038] The transparent observation window 9 allows operators to easily observe the inside of the feeding cylinder 4. When no more material falls from the bottom of the outlet hole 24, it means that the material in the bag has completely fallen.

[0039] The side of the feeding cylinder 4 is fixed with an operating platform 1 by bolts, and a support column 2 is welded to the bottom of the operating platform 1.

[0040] The operating platform 1 and the support column 2 can support the feeding cylinder 4.

[0041] A ladder 3 is fixed to one side of the outer wall of the operating platform 1 by bolts;

[0042] Ladder 3 allows operators to climb to the top of the operating platform 1 and move the material bag into the placement box 20.

[0043] Both sides of the outer wall of the placement box 20 are fixed with electric telescopic rods 17 by bolts, and the output end of the electric telescopic rods 17 is fixed with clamps 23.

[0044] As material is continuously fed into the bag through the discharge hole 24, to prevent the bag from falling into the feeding cylinder 4 after the material is emptied, the operator can observe the inside of the placement box 20 through the transparent observation window 9. When about half of the material in the bag is discharged, the electric telescopic rod 17 is controlled to drive the clamping plate 23 to move laterally. During the relative movement of the two clamping plates 23, the emptying position of the bag is clamped and fixed, thereby preventing the subsequent bag from falling into the feeding cylinder 4 through the discharge hole 24.

[0045] A controller 7 is installed on the side of the feeding cylinder 4;

[0046] The controller 7 can control the start, stop, direction and speed of the drive motor 11 through electrical connection according to the preset program or the instructions input by the operator, thereby driving the hollow column 19 and the rotating plate 21 to rotate as required, so as to realize the alignment and misalignment operation of the feeding hole 22; at the same time, it can control the extension and retraction of the electric telescopic rod 6, drive the moving rod 14 to move steadily upward in the vertical direction, and drive the blade 16 to pass through the outlet hole 24 to cut the bottom of the material bag; in addition, it can also control the electric telescopic rod 17 to drive the clamping plate 23 to move laterally, and after a certain amount of material is discharged from the material bag, it can clamp and fix the empty position of the material bag in a timely and stable manner to prevent the material bag from falling.

[0047] Working principle: The controller 7 starts the drive motor 11, which drives the hollow column 19 and the rotating plate 21 to rotate through the meshing of gear 18 and gear 13. The rotating plate 21 is aligned with the feeding hole 22 on the top plate 5. After the material bag is placed into the placement box 20, the controller drives the rotation again. After the bottom of the placement box 20 is misaligned with the fan-shaped plate 8, the controller 7 controls the electric telescopic rod 6 to drive the moving rod 14 to move upward, which drives the blade 16 to pass through the outlet hole 24 to cut the material bag. The material falls into the bottom of the feeding cylinder 4. After the feeding is completed, the controller 7 controls the hollow column 19 and the rotating plate 21 to rotate in the opposite direction to reset. The operator observes through the transparent observation window 9. When about half of the material in the material bag is discharged, the controller 7 controls the electric telescopic rod 17 to drive the clamping plate 23 to move laterally to clamp the material bag and prevent it from falling.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
