Description

Technical Field

[0001] This utility model relates to the technical field of plastic discharge devices, specifically a hopper rotary discharge device. Background Technology

[0002] The hopper rotary discharge device is a device that achieves directional output of materials through mechanical rotation. It is mainly used to process bulk materials such as crushed plastic granules. Its core principle is to use rotating parts to evenly discharge materials from the bottom of the storage bin and achieve continuous feeding through centrifugal force or gravity.

[0003] In the existing technology, most common plastic pellet discharge devices adopt a structure with a fixed hopper and independent valve control. Multi-outlet hoppers require a separate valve for each discharge channel. Multiple valves or sealing components increase costs and require frequent maintenance. Smaller particles are prone to bridging and clogging at the discharge port, requiring manual intervention for cleaning. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hopper rotary discharge device to solve the problem that existing discharge holes are easily clogged and require manual intervention for cleaning.

[0005] This utility model discloses a hopper rotary discharge device, comprising a hopper, a base, a material diversion structure, a discharge structure, and a drive unit. A bearing is installed in the center of the bottom of the hopper, and a discharge hole is opened on one side of the bottom of the hopper. The base is fixedly connected to the bottom of the inner wall of the hopper, and a through hole is opened in the middle of the base. The material diversion structure is fixedly connected to the upper part of the inner wall of the through hole. The discharge structure is disposed inside the through hole and located below the material diversion structure. The discharge structure is rotatably connected to the hopper through the bearing. The drive unit is disposed on the lower surface of the hopper and is used to drive the discharge structure to rotate.

[0006] As a further improvement of this utility model, the material diversion structure includes a first baffle, which is a fan-shaped plate. A connecting plate is integrally formed at the center of the first baffle, and a second baffle is fixedly connected to the side of the connecting plate away from the first baffle in a ring.

[0007] As a further improvement of this utility model, the first baffle is located directly above the discharge hole, and the area of ​​the first baffle is larger than the area of ​​the discharge hole.

[0008] As a further improvement of this utility model, the discharge structure includes a rotating shaft, a connecting shaft is fixedly connected to the middle of one end of the rotating shaft, the connecting shaft is fixedly connected to the inner ring of the bearing, and blades are fixedly connected to the surface of the rotating shaft at equal intervals in a ring. The upper surface of the blades is in contact with the lower surface of the material diversion structure, and the lower surface of the blades is in contact with the bottom of the inner wall of the hopper.

[0009] As a further improvement of this utility model, a screw is fixedly connected to one end of the rotating shaft near the material diversion structure. The end of the screw passes through the material diversion structure and is threadedly connected to a movable plate. A locking nut is threadedly connected to the end of the screw.

[0010] As a further improvement of this utility model, the lower surface of the movable plate is attached to the upper surface of the material diversion structure.

[0011] As a further improvement of this utility model, the drive unit includes a housing fixedly connected to the lower surface of the hopper. A connecting hole is provided on the upper surface of the housing at the position corresponding to the bearing. One end of the rotating shaft passes through the connecting hole and is fixedly connected to a first transmission wheel. A motor is fixedly connected to the bottom of the inner wall of the housing. A second transmission wheel is fixedly connected to the output end of the motor. A transmission belt is installed between the first transmission wheel and the second transmission wheel.

[0012] As a further improvement of this utility model, a recessed portion facing the center of the discharge hole is provided on the center of the upper surface of the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The material diversion structure of this utility model is fixed above the through hole, and its fan-shaped baffle covers the discharge hole to form a barrier, preventing the material from falling directly from the discharge hole. The material can only flow through the gap generated by the rotation of the blades. This design forcibly changes the natural accumulation form of the material, allowing the material to fall from the discharge hole in batches, thereby preventing the discharge hole from becoming blocked. The device does not have a valve, and the material will stop falling when the motor is turned off. Compared with traditional discharge devices, the maintenance cost is significantly reduced.

[0015] 2. This utility model uses a screw installed at the top of the rotating shaft, and a movable plate installed on the screw that fits against the upper surface of the first baffle. When the rotating shaft is driven by the motor to rotate, the movable plate will also rotate, thereby pushing the material above the first baffle and causing the material on the first baffle to fall off, thus preventing the material from accumulating above the first baffle. At the same time, it can also make the material in the hopper move, further preventing blockage and avoiding manual cleaning due to blockage. Attached Figure Description

For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] In the description of this technology, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0028] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0029] Please see Figure 1-7 This utility model discloses a hopper rotary discharge device, comprising a hopper 1, a base 4, a material diversion structure, a discharge structure, and a drive unit. A bearing 3 is installed in the center of the bottom of the hopper 1, and a discharge hole 2 is provided on one side of the bottom of the hopper 1. The base 4 is fixedly connected to the bottom of the inner wall of the hopper 1, and a through hole 5 is provided in the middle of the base 4. The discharge hole 2 is located inside the through hole 5. A recessed part facing the center of the discharge hole 2 is provided in the center of the upper surface of the base 4. The material diversion structure is fixedly connected to the upper part of the inner wall of the through hole 5. The discharge structure is located inside the through hole 5 and below the material diversion structure. The discharge structure is rotatably connected to the hopper 1 through the bearing 3. The drive unit is provided on the lower surface of the hopper 1 and is used to drive the discharge structure to rotate.

[0030] In this embodiment, the material diversion structure includes a first baffle 6, which is a fan-shaped plate. A connecting plate 7 is integrally formed at the center of the first baffle 6. A second baffle 8 is fixedly connected to the side of the connecting plate 7 away from the first baffle 6 in a ring shape. The first baffle 6 is located directly above the discharge hole 2, and the area of ​​the first baffle 6 is larger than the area of ​​the discharge hole 2.

[0031] Through the above technical solution, the first baffle 6 with the fan-shaped structure can be fixed to the inner wall of the through hole 5 and fit against the inner wall of the through hole 5. The second baffle 8 with the ring arrangement can play a certain role in diverting the material and prevent the material from falling in a concentrated manner. The first baffle 6 is located directly above the discharge hole 2 and has a larger area than the discharge hole 2, which can prevent the material from falling directly from the discharge hole 2 and play a blocking effect on the material, avoiding the blockage caused by the concentrated falling of the material.

[0032] In this embodiment, the discharge structure includes a rotating shaft 9, a connecting shaft 14 is fixedly connected to the middle of one end of the rotating shaft 9, the connecting shaft 14 is fixedly connected to the inner ring of the bearing 3, and blades 10 are fixedly connected to the surface of the rotating shaft 9 at equal intervals in a ring. The upper surface of the blades 10 is in contact with the lower surface of the material diversion structure, and the lower surface of the blades 10 is in contact with the bottom of the inner wall of the hopper 1.

[0033] By using a rotating shaft 9 in the discharge structure, along with blades 10 fixed in a ring on the surface of the rotating shaft 9, the distance between two adjacent blades 10 can accommodate a certain amount of material. The rotation of the blades 10 pushes the material to the discharge hole 2, achieving the purpose of intermittent rotational discharge. When the blades 10 stop rotating, the material will be blocked between the blades 10 and will no longer fall. This replaces the traditional method of controlling the discharge through valves, and the maintenance cost is significantly reduced compared to traditional discharge devices.

[0034] In some other embodiments, a screw 11 is fixedly connected to one end of the rotating shaft 9 near the material diversion structure. The end of the screw 11 passes through the material diversion structure and is threadedly connected to a movable plate 12. A locking nut 13 is threadedly connected to the end of the screw 11. The lower surface of the movable plate 12 is in contact with the upper surface of the material diversion structure.

[0035] With the above technical solution, when the rotating shaft 9 rotates, the movable plate 12 on the rotating shaft 9 will also rotate. The rotating movable plate 12 can push the material above the first baffle 6, causing the material on the first baffle 6 to fall off. At the same time, it can also make the material in the hopper 1 move, further preventing blockage.

[0036] In this embodiment, the drive unit includes a housing 16 fixedly connected to the lower surface of the hopper 1. A connecting hole 17 is provided on the upper surface of the housing 16 at the position corresponding to the bearing 3. One end of the rotating shaft 9 passes through the connecting hole 17 and is fixedly connected to a first transmission wheel 15. A motor 18 is fixedly connected to the bottom of the inner wall of the housing 16. A second transmission wheel 19 is fixedly connected to the output end of the motor 18. A transmission belt 20 is installed between the first transmission wheel 15 and the second transmission wheel 19.

[0037] With the first transmission wheel 15, the second transmission wheel 19, the transmission belt 20 and the motor 18, the operator only needs to start the motor 18 to make the rotating shaft 9 rotate, thereby achieving the purpose of rotating material discharge.

[0038] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
