Description

A stable feeding mechanism Technical Field

[0001] This utility model relates to the field of feeding machine technology, specifically a stable feeding mechanism. Background Technology

[0002] As is well known, in industrial production, the feeding mechanism is one of the key pieces of equipment ensuring a continuous and uniform supply of materials to the production line. However, in practical applications, especially when handling materials with different moisture levels or types, traditional feeding mechanisms often face numerous challenges. For certain materials, particularly those with high moisture content or prone to caking, such as damp powders or granules, these materials may accumulate and clog after entering the feed hopper due to their moisture content. Once a blockage occurs, it not only interrupts the normal feeding process but also requires manual intervention for cleaning, which greatly affects the continuity and efficiency of production. Traditional feeding mechanisms may not be able to guarantee a uniform supply of materials, especially when handling materials of different types or moisture levels. Due to the lack of an effective anti-clogging mechanism, the feeding speed is prone to instability, which in turn affects the quality and efficiency of subsequent processing. Therefore, it is necessary to propose solutions to this technical problem. Summary of the Invention

[0013] Furthermore, the present invention is improved in that the scraper is provided in a plurality of them and arranged in a circular array.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a stable feeding mechanism, which has the following beneficial effects:

[0016] This stable feeding mechanism, when encountering situations where materials of varying moisture content or type tend to accumulate in the feed hopper, causing blockages, utilizes a control telescopic mechanism to move the toothed block. After the toothed block disengages from the gear, the regulating motor drives the gear to rotate, which in turn rotates the meshing gear ring. The rotation of the gear ring causes the regulating ring and the scraper mounted on it to rotate together. The scraper effectively pushes and removes the accumulated material in the feed hopper, preventing blockages. For materials less prone to blockages, such as dry granular materials, there is no need to start the regulating motor. In this case, the control telescopic mechanism allows the toothed block to directly abut against the gear, locking the angle of the regulating ring and keeping the scraper position unchanged. This simplifies the operation process and allows for flexible selection of whether to activate the scraper rotation function according to actual needs, improving the adaptability and flexibility of the equipment. Because this structure effectively prevents downtime for cleaning due to material blockages, it reduces unnecessary downtime, thereby greatly improving production efficiency. Simultaneously, by reducing the need for manual intervention, it also reduces maintenance costs and labor input. Attached Figure Description

[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] Please refer to Figures 1-4. This utility model is a stable feeding mechanism, including a screw conveyor 1. The screw conveyor 1 is equipped with a screw mechanism. The top of the screw conveyor 1 is equipped with a feed hopper 2, an adjusting motor 3, and a mounting frame 4. The feed hopper 2 is equipped with a sealing box 5, and the sealing box 5 has a feed inlet. The feed inlet has an adjusting groove, and the adjusting groove is equipped with a bearing seat 6. The bearing seat 6 is equipped with an adjusting ring 7. The outer side of the adjusting ring 7 is equipped with a toothed ring 8. The inner side of the adjusting ring 7 is provided between the feed hopper 2 and the feed hopper 2. The output end of the adjusting motor 3 is... A gear 10 extends into the interior of the sealed box 5 and is provided thereon. The gear 10 meshes with the gear ring 8. A telescopic mechanism 11 is provided on the mounting frame 4. The output end of the telescopic mechanism 11 extends into the interior of the sealed box 5 and is provided with a toothed block 12. The toothed block 12 meshes with the gear 10. A guide mechanism is provided between the toothed block 12 and the interior of the sealed box 5. In this embodiment, the material is easily poured into the sealed box 5 through the feed port on the feed hopper 2. The material enters the interior of the screw conveyor 1 from the feed hopper 2, and then the screw mechanism is activated to screw-convey the material, thereby facilitating the conveying of the material. The screw conveyor 1 provides stable material transport and can operate at a uniform feeding speed. However, materials of different moisture content or types are prone to accumulating and causing blockages in the feed hopper 2, affecting normal feeding. By controlling the output end of the telescopic mechanism 11 to linearly move the toothed block 12 away from the gear 10, the output end of the regulating motor 3 is controlled to rotate the gear 10. The gear 10 meshes with the gear ring 8, allowing the gear ring 8 to rotate with the gear 10. The gear ring 8 drives the regulating ring 7 to rotate, and the regulating ring 7 rotates stably via the bearing seat 6. The regulating ring 7 then drives the scraper 9 to move. 9 can effectively push and scrape away the material accumulated on the feed hopper 2, ensuring that the material is evenly fed into the screw conveyor 1, thereby achieving stable and reliable feeding operations. When using non-clogging materials such as dry granular materials into the feed hopper 2, there is no need to use the adjusting motor 3. By controlling the output end of the telescopic mechanism 11 to move linearly, the toothed block 12 engages with the gear 10, thereby locking the angle of the adjusting ring 7 and ensuring that the scraper 9 will not have an angle gap. It can flexibly select whether to turn on the scraper 9 to prevent clogging according to the type of material. It is convenient to use and has good feeding stability.

[0024] In this solution, the spiral mechanism includes a drive motor 13 and a spiral shaft 14. The spiral shaft 14 is located inside the spiral conveyor 1. The drive motor 13 is installed at one end of the spiral conveyor 1, and the output end of the drive motor 13 is connected to the spiral shaft 14. By controlling the output end of the drive motor 13 to rotate the spiral shaft 14, the spiral shaft 14 can rotate at a stable angle inside the spiral conveyor 1, enabling the spiral shaft 14 to convey the material fed from the feed hopper 2 at a uniform speed, thus achieving stable material conveying during the production process.

[0025] In this solution, the guiding mechanism includes a guide groove 15 and a guide block 16. The guide groove 15 is formed on one side of the inner wall of the sealing box 5, and the guide block 16 is located in the guide groove 15. The guide block 16 is connected to the toothed block 12. When the toothed block 12 moves, the toothed block 12 drives the guide block 16 to move linearly. The guide block 16 slides in the guide groove 15, which can improve the linear movement stability of the toothed block 12 and the stability of the toothed block 12 meshing with the gear 10.

[0026] In this solution, two guide mechanisms are provided and symmetrically arranged. The smoothness of linear movement of the tooth block 12 can be improved by using two symmetrically arranged guide mechanisms.

[0027] In this design, both the guide groove 15 and the guide block 16 are T-shaped structures. The T-shaped guide groove 15 and guide block 16 can further improve the linear movement stability of the guide block 16 in the guide groove 15.

[0028] In this scheme, both the drive motor 13 and the regulating motor 3 are servo motors. Servo motors have the characteristic of high rotational accuracy, which can improve the control accuracy when this structure is used.

[0029] In this solution, the telescopic mechanism 11 is an electric telescopic rod. The electric telescopic rod has the characteristics of high movement accuracy and good stability, which can improve the linear movement stability of the tooth block 12.

[0030] In this scheme, the scraper 9 is provided in a multiple and circular array, and the multiple array of scraper 9 can scrape the material on the inner wall of the feed hopper 2 more efficiently.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
