Abstract
Description
Technical Field
[0001] This utility model relates to the field of dry granulation machine technology, specifically a dry granulation machine with a vibrating feeding device. Background Technology
[0002] Dry granulation machines are devices that directly compress dry powdery materials into particles of specific shapes and sizes using mechanical pressure. Their function is to transform loose powder into granules with uniform density and good flowability without the need for binders or liquid media, relying solely on high-pressure roller pressing or molding technology to generate mechanical interlocking and binding forces between material particles. This improves the compressibility, solubility, and storage stability of the material while avoiding the drying process of wet granulation. They are widely used in industries such as pharmaceuticals, food, chemicals, and fertilizers where high particle strength, purity, and production efficiency are required.
[0003] In the current practical use of dry granulation machines, after the granulation process is completed, a small amount of finished granules often get stuck in the crushing trough. These stuck granules hinder the normal operation of the equipment, making it impossible to continue granulation smoothly. Moreover, after granulation, some powder remains inside the components. If this residual powder is not cleaned in a timely and effective manner, it will interfere with the uniform mixing and normal pressing of the material in the next granulation, thus causing instability in the granulation process and resulting in inconsistent quality of the produced granules, which brings certain problems to the continuous and stable production of enterprises. Utility Model Content
[0004] The purpose of this invention is to provide a dry granulator with a vibrating feeding device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a dry granulator with a vibrating feeding device, comprising a dry granulator body, and further comprising: a rotating shaft rotating on the surface of the dry granulator body, wherein a granulating block is fixed on the surface of the rotating shaft, a vibration mechanism is provided on the surface of the dry granulator body, a scraping mechanism is provided on the surface of the dry granulator body, and a motor is fixed on the surface of the dry granulator body.
[0006] Preferably, the vibration mechanism further includes: A fixing block is fixed to the surface of the dry granulator body, and a vibrating rod is fixed to the surface of the fixing block. Several striking blocks are fixed to the surface of the granulation block.
[0007] Preferably, the scraping mechanism further includes: A first meshing tooth is fixed to the surface of a rotating shaft. A gear meshes on the surface of the first meshing tooth. A limit block rotates on the surface of the gear. A second meshing tooth meshes on the surface of the gear. A reciprocating threaded rod is fixed on the surface of the second meshing tooth. A scraping block meshes on the surface of the reciprocating threaded rod.
[0008] Preferably, the motor is a servo motor and has a dual-axis drive.
[0009] Preferably, the scraping block has a plastic meshing end and a bristle end that contacts the granulation block.
[0010] Preferably, the striking block is wedge-shaped and has a smooth surface.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a vibration mechanism to solve production problems. This vibration mechanism, with the help of its own parts and the power of the equipment, continuously generates vibration. Under this regular vibration, the finished granules that were originally attached to the surface of the equipment and were not easy to fall off naturally are effectively shaken off, avoiding the impact of granule residue on subsequent production. At the same time, the scraping mechanism repeatedly sweeps the granulation block through reciprocating motion. In this process, not only can the residual powder on the surface of the granulation block be cleaned up to ensure the cohesion during the next granulation, but also those granules that have not yet been shaken off can be swept off as well, further improving the cleanliness of the equipment and the stability of production.

[0014] 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.
[0015] Please see Figure 1-4 As shown, a dry granulator with a vibrating feeding device includes a dry granulator body 1, a rotating shaft 2 rotating on the surface of the dry granulator body 1, a granulation block 3 fixed on the surface of the rotating shaft 2, a vibration mechanism 4 provided on the surface of the dry granulator body 1, a scraping mechanism 5 provided on the surface of the dry granulator body 1, and a motor 6 fixed on the surface of the dry granulator body 1.
[0016] The motor 6 is fixed to the surface of the dry granulator body 1 to provide power to the internal equipment and drive other components with strong driving force.
[0017] Motor 6 is a servo motor with internal dual-axis drive, providing strong driving force to ensure the power required for crushing into pellets.
[0018] The rotating shaft 2 rotates on the surface of the dry granulator body 1, and under the drive of the motor 6, it transmits force to other parts.
[0019] The granulation block 3 is fixed on the surface of the rotating shaft 2. Driven by the motor 6, the power is converted into a cohesive force that crushes the raw material into granules. Through cohesive crushing, the powder is agglomerated into granules.
[0020] Vibration mechanism 4 is set on the surface of dry granulator body 1. Through the continuous rotation of rotating shaft 2, it drives the fixed parts on its surface, thereby continuously moving the parts, thus generating continuous impact and vibration, shaking off the finished granules that have not fallen off the surface of granulation block 3, thereby improving production efficiency.
[0021] The vibration mechanism 4 includes a fixed block 41 fixed to the surface of the dry granulator body 1, a vibration rod 42 fixed to the surface of the fixed block 41, and several striking blocks 43 fixed to the surface of the granulation block 3.
[0022] The fixing block 41 is fixed to the surface of the dry granulator body 1, which supports the vibrating rod 42 and ensures that it remains stable when it is constantly being moved and deformed, so as not to fall off or break due to stress.
[0023] The vibrating rod 42 is fixed to the surface of the fixed block 41 and is used to continuously strike the striking block 43 to generate vibration, so that the granulation block 3 continuously forms slight vibration, thereby shaking off the product attached to the surface of the granulation block 3.
[0024] The vibrating rod 42 is made of high-strength plastic, which has strong anti-aging ability. Under the continuous plucking of the striking block 43, it deforms and recovers. Its characteristics can prevent it from breaking due to aging and increase its service life.
[0025] The striking blocks 43 are fixed to the surface of the granulation block 3. There are ten of them. They are used to actuate the vibrating rod 42. When the rod recovers after deformation, it will strike the next striking block 43 to generate vibration. The vibration is generated by the equipment itself. No new power is needed, which greatly reduces energy damage and lowers costs.
[0026] The striking block 43 is wedge-shaped and has a smooth surface to ensure that it will not scratch the vibrating rod 42 after sliding on the surface, thereby causing deformation and affecting its next use.
[0027] The scraping mechanism 5 is set on the surface of the dry granulator body 1. The scraping parts set on it are driven by the power brought by the rotating shaft 2 to sweep and scrape the granulation block 3, thereby cleaning the residual raw material powder on the surface, which greatly increases the probability of granulation and improves its efficiency.
[0028] The scraping mechanism 5 includes a first meshing tooth 51 fixed to the surface of the rotating shaft 2, a gear 52 meshing on the surface of the first meshing tooth 51, a limit block 53 rotating on the surface of the gear 52, a second meshing tooth 54 meshing on the gear 52, a reciprocating threaded rod 55 fixed to the surface of the second meshing tooth 54, and a scraping block 56 meshing on the surface of the reciprocating threaded rod 55.
[0029] The first meshing tooth 51 is fixed to the surface of the rotating shaft 2, and under the drive of the rotating shaft 2, it transmits power to the gear 52 that is in contact with its surface.
[0030] Gear 52 rotates on the surface of the dry granulator body 1. As a medium, the power transmitted from the rotating shaft 2 is transmitted through gear 52 to the surface of the second meshing tooth 54 at the other end. By using simple mechanical transmission, the maximum energy utilization is achieved.
[0031] The limiting block 53 slides on the surface of the gear 52 to limit the gear 52 and ensure that it will not fall off during rotation, thus preventing instability.
[0032] The second meshing tooth 54 is fixed to the surface of the reciprocating threaded rod 55 and is used to transmit the power from the rotating shaft 2 to the surface of the reciprocating threaded rod 55.
[0033] The reciprocating threaded rod 55 rotates on the inner wall of the dry granulator body 1. Through the bidirectional threaded groove opened above, the scraping block 56 on it can reciprocate, thereby repeatedly sweeping the surface of the granulation block 3, cleaning the groove of the particles that have been shaken off, and pushing out the particles that have not been shaken off under the sweeping of the scraping block 56.
[0034] The scraping block 56 engages with the surface of the reciprocating threaded rod 55, and under the drive of the reciprocating threaded rod 55, it continuously scrapes away residual powder and unshed particles.
[0035] The scraping block 56 has a plastic meshing end and a bristle end that contacts the granulation block 3, ensuring that it sweeps and scrapes cleanly and reducing friction with the granulation block 3, thus reducing wear.
[0036] The limiting rod 57 is fixed to the surface of the dry granulator body 1. When the scraping block 56 engages and moves on the surface of the reciprocating threaded rod 55, the limiting rod 57 will restrict its rotation to prevent the friction generated during engagement from causing it to rotate and affecting the sweeping effect.
[0037] Working principle: When dry granulation is required, the operator starts the motor 6. Driven by the motor 6, the machine begins to operate, and the rotating shaft 2 is rotated, which in turn drives the fixed granulation block 3 to rotate. As the granulation block 3 rotates, granules are continuously produced. Driven by the granulation block 3, the striking block 43 moves continuously, which causes the vibrating rod 42 to bend and then return to its original shape. During the return process, it strikes the next striking block 43, generating vibration. The generated vibration causes the granules accumulated on the surface of the granulation block 3 to... The particles fall off, thus reducing the probability of blockage and accumulation. Under the transmission of gear 52, as the rotating shaft 2 rotates continuously, the reciprocating threaded rod 55 is rotated by the external force brought by the second meshing tooth 54. As the second meshing tooth 54 rotates, the scraping block 56 that meshes with it moves continuously on its surface, and under the limit of the limiting rod 57, it is prevented from rotating on its own. Under the reciprocating sweeping and scraping of the scraping block 56, the powder and particles that have not fallen off automatically on the surface of the granulation block 3 will be cleaned up, so as not to affect the next molding.
