Abstract
Description
Technical Field
[0001] This utility model relates to the field of material feeding technology, and in particular to a high-efficiency automatic material feeding device for an open mill. Background Technology
[0002] An open mixing mill, also known as an open rubber mixing mill, is a commonly used piece of machinery in the processing industry of rubber, plastics and other polymer materials. It is used to fully mix and plasticize raw materials. Traditional manual feeding requires frequent operation by workers, which is not only labor-intensive but also inefficient. Automatic feeding devices can reduce manual operation and lower labor intensity.
[0003] Existing high-efficiency automatic feeding devices for open mills typically involve feeding raw materials into a storage hopper, where a clearing component unclogs the hopper to reduce blockages. Additionally, a dispersing component evenly distributes the raw materials in a dispersion bin, ensuring the material falls evenly between the two open mill rolls, reducing material accumulation on the rolls and improving processing efficiency. However, this method cannot adequately agitate the raw materials, leading to uneven mixing and affecting the physical and chemical properties of the product, reducing overall quality. Furthermore, the accumulation of raw materials inside the equipment increases operating resistance and energy consumption. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a high-efficiency automatic feeding device for open mills, aiming to improve the problem that existing high-efficiency automatic feeding devices for open mills cannot fully mix the raw materials.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency automatic feeding device for an open mill, comprising an open mill body, support plates fixedly connected to both upper sides of the open mill body, a storage hopper fixedly connected to one side of each of the two support plates, a fixed seat fixedly connected to both outer sides of the storage hopper, a hydraulic cylinder fixedly connected inside the left fixed seat, a push plate fixedly connected to the output end of the hydraulic cylinder, an mounting plate fixedly connected to the right side of the push plate, a limit component fixedly connected to the right side of the mounting plate, the limit component being used to limit the mounting plate, a motor fixedly connected to the upper part of the mounting plate, a rotating shaft fixedly connected to the output end of the motor, stirring blades fixedly connected to the outer periphery of the rotating shaft, and a feeding pipe fixedly connected to the bottom of the storage hopper.
[0006] Furthermore, a partition plate 2 and a positioning plate are fixedly connected inside the storage hopper. A motor 2 is fixedly connected to the upper part of the positioning plate. A baffle is fixedly connected to the output end of the motor 2. The baffle is rotatably connected to the upper part of the partition plate 2. Discharge holes are opened on all four sides of the interior of the partition plate 2. The baffle is rotatably connected to the upper part of the discharge holes.
[0007] Furthermore, the limiting component includes a sliding plate and a sliding rod, the sliding plate being fixedly connected to the right side of the mounting plate and slidably connected to the outside of the sliding rod.
[0008] Furthermore, the slide rod is fixedly connected inside the right-side fixed seat, and a compression spring is sleeved on the outside of the slide rod.
[0009] Furthermore, one end of the compression spring is fixedly connected to the inside of the right-side fixing seat, and the other end of the compression spring is fixedly connected to the bottom of the slide plate.
[0010] Furthermore, the rotating shaft is rotatably connected to the inside of the storage hopper, and the plurality of stirring blades are also rotatably connected to the inside of the storage hopper.
[0011] Furthermore, limit blocks are fixedly connected to both sides of the bottom of the baffle, and a limit frame is fixedly connected inside the partition plate 2. Both limit blocks are slidably connected inside the limit frame.
[0012] Furthermore, a partition is fixedly connected inside the storage hopper, and a discharge port is opened inside the partition.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the hydraulic cylinder is activated to push the push plate, which in turn moves the mounting plate. The mounting plate then drives the motor to move. Once the motor starts, the rotating shaft and stirring blades move up and down and rotate within the storage hopper to stir the raw materials. This effectively adjusts the height of the stirring blades to ensure thorough mixing of the components, thereby improving uniformity and mixing effect.
[0015] 2. In this utility model, by starting motor two, the baffle is driven to rotate. The baffle moves away from the upper part of the discharge hole, and the raw material is discharged through the discharge hole. The baffle rotates to the upper part of the discharge hole to block the raw material from falling, thereby achieving precise control of the feeding amount, ensuring the accuracy of the amount of material added to the open mill, and improving the stability of product quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-3This utility model provides an embodiment of a high-efficiency automatic feeding device for an open mill, comprising an open mill body 1, support plates 2 fixedly connected to both sides of the upper part of the open mill body 1, storage hoppers 3 fixedly connected to opposite sides of the two support plates 2, fixed seats 5 fixedly connected to both sides of the outer side of the storage hoppers 3, a hydraulic cylinder 6 fixedly connected inside the left fixed seat 5, a push plate 7 fixedly connected to the output end of the hydraulic cylinder 6, a mounting plate 11 fixedly connected to the right side of the push plate 7, a limit component fixedly connected to the right side of the mounting plate 11, the limit component being used to limit the mounting plate 11, and a motor 12 fixedly connected to the upper part of the mounting plate 11. A rotating shaft 13 is fixedly connected to the output end. Stirring blades 14 are fixedly connected to the outer periphery of the rotating shaft 13. A discharge pipe 4 is fixedly connected to the bottom of the storage hopper 3. The limiting assembly includes a sliding plate 8 and a sliding rod 9. The sliding plate 8 is fixedly connected to the right side of the mounting plate 11. The sliding plate 8 is slidably connected to the outside of the sliding rod 9. The sliding rod 9 is fixedly connected to the inside of the right fixed seat 5. A compression spring 10 is sleeved on the outside of the sliding rod 9. One end of the compression spring 10 is fixedly connected to the inside of the right fixed seat 5, and the other end of the compression spring 10 is fixedly connected to the bottom of the sliding plate 8. The rotating shaft 13 is rotatably connected to the inside of the storage hopper 3, and multiple stirring blades 14 are rotatably connected to the inside of the storage hopper 3.
[0024] The storage hopper 3 is a container for temporarily storing raw materials. The raw materials are first put into the storage hopper 3, waiting for subsequent stirring and processing. After the raw materials are put into the storage hopper 3, the hydraulic cylinder 6 is activated, and its output end pushes the push plate 7 forward. As the push plate 7 moves, the mounting plate 11 and the sliding plate 8 are driven accordingly. The sliding plate 8 moves smoothly along the outside of the sliding rod 9. The sliding plate 8 moves along the outside of the sliding rod 9 to transmit the force of the push plate 7. The sliding rod 9 provides a guiding and supporting surface so that the sliding plate 8 can move smoothly along its outside. During this process, the sliding plate 8 applies tensile or compressive force to the compression spring 10. The compression spring 10 is used to buffer the movement and provide rebound force when necessary. Under the combined action of the push plate 7 and the sliding plate 8, the mounting plate 11 carries the motor 12 to move synchronously. When the motor 12 drives the rotating shaft 13 and the stirring blade 14 to move up and down in the storage hopper 3, the motor 12 is started. The output end of the motor 12 drives the rotating shaft 13 to rotate, thereby driving the stirring blade 14 to rotate in the storage hopper 3, so as to efficiently stir the raw materials.
[0025] Reference Figure 3 and Figure 4The storage hopper 3 is internally fixedly connected to a partition plate 16 and a positioning plate 17. A motor 18 is fixedly connected to the upper part of the positioning plate 17. A baffle 19 is fixedly connected to the output end of the motor 18. The baffle 19 is rotatably connected to the upper part of the partition plate 16. Discharge holes 22 are opened on all four sides of the interior of the partition plate 16. The baffle 19 is rotatably connected to the upper part of the discharge holes 22. Limiting blocks 20 are fixedly connected to both sides of the bottom of the baffle 19. A limiting frame 21 is fixedly connected inside the partition plate 16. The two limiting blocks 20 are slidably connected inside the limiting frame 21. The storage hopper 3 is internally fixedly connected to a partition plate 15. A discharge port is opened inside the partition plate 15.
[0026] After mixing, the raw materials are smoothly conveyed downwards through the discharge port built into the partition 15. At this moment, the motor 18 starts, and its output drives the baffle 19 to rotate. As the baffle 19 rotates, the limiting block 20 slides accordingly inside the limiting frame 21. The limiting frame 21 provides a sliding track for the limiting block 20, ensuring that the movement of the limiting block 20 is controlled and orderly, while also limiting the rotation range of the baffle 19. When the baffle 19 leaves the upper end of the discharge hole 22, the raw materials can pass through the discharge port. The material is discharged smoothly from the discharge hole 22 and slides down the feed pipe 4 to the position between the two rollers in the open mill body 1. Once the baffle 19 rotates above the discharge hole 22, it will block the discharge hole 22 in time to prevent the raw material from continuing to flow out. The baffle 19 is a key component for controlling the flow of raw material. Its rotation determines whether the raw material can be discharged through the discharge hole 22. When the baffle 19 moves away from the discharge hole 22, the raw material can be discharged. Conversely, when the baffle 19 covers the discharge hole 22, the discharge of the raw material is blocked.
[0027] Working principle: First, the raw materials are put into the storage hopper 3. The hydraulic cylinder 6 is started, and the output end of the hydraulic cylinder 6 pushes the push plate 7 to move. When the push plate 7 moves, it drives the mounting plate 11 and the sliding plate 8 to move. When the sliding plate 8 moves, it slides outside the sliding rod 9. The movement of the sliding plate 8 stretches or compresses the compression spring 10. Under the action of the push plate 7 and the sliding plate 8, the mounting plate 11 drives the motor 12 to move. When the motor 12 drives the rotating shaft 13 and the stirring blade 14 to move up and down inside the storage hopper 3, the motor 12 is started. The output end of the motor 12 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the stirring blade 14 to rotate inside the storage hopper 3, stirring the raw materials. This allows for convenient adjustment of the height of the stirring blade 14 to stir the raw materials, ensuring the raw materials are stirred properly. The various components are fully mixed, improving the uniformity of the raw materials and optimizing the mixing effect. After the raw materials are stirred, they are conveyed downward through the discharge port inside the partition 15. At this time, the motor 18 is started, and the output end of the motor 18 drives the baffle 19 to rotate. When the baffle 19 rotates, it drives the limiting block 20 to slide inside the limiting frame 21. When the baffle 19 moves away from the upper part of the discharge hole 22, the raw materials are discharged downward through the discharge hole 22 and fall through the feeding pipe 4 into the space between the two open mill rolls inside the open mill body 1. When the baffle 19 rotates to the upper part of the discharge hole 22, it blocks the discharge hole 22 to prevent the raw materials from falling further. This enables precise control of the feeding amount, ensuring that the amount of material added to the open mill each time is accurate and improving the stability of product quality.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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 described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
