Description

Technical Field

[0001] The utility model belongs to the technical field of material forming devices, in particular to a powdery material forming device. Background Art

[0002] The molding and processing of powdered materials is a crucial step in modern industrial production, widely used in the pharmaceutical, food, and chemical industries. Powder molding equipment is typically used to convert loose powdered materials into solid products with a defined shape and density, such as tablets, food blocks, or industrial granules, through compression or other processes. While traditional powder molding equipment offers a variety of functions, operational issues such as uneven pressure distribution, instability, and complex operation can still affect product quality and production efficiency.

[0003] The tableting process in traditional equipment often relies on complex mechanical structures, often including multiple layers of transmission components and intricate power systems. While this design achieves basic tableting functions, it also results in bulky equipment, complex operation, and difficult maintenance. Furthermore, wear and play between transmission components can easily lead to uneven pressure transmission during tableting, compromising the quality of the finished product. This is particularly evident when producing high-precision, high-consistency products.

[0004] Furthermore, traditional powdered material forming devices often experience vibration or displacement during the tableting process due to an instable frame structure. This not only affects tableting accuracy but can also damage the equipment's long-term performance. Furthermore, in some devices, the connection between the tableting head and the mold is not optimized, so the pressure from the tableting head cannot be evenly applied to the entire mold, resulting in uneven density of the formed material and substandard finished product quality.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] refer to Figure 1 and 2 As shown, the utility model discloses a powder material forming device, comprising a frame 1, a tablet pressing mold 2 and a tablet pressing device 3;

[0025] Specifically, the tableting mold 2 includes an outer mold 2.1 and a core 2.2. The core 2.2 is a cylindrical structure and is disposed within the outer mold 2.1. The outer mold 2.1 is a sleeve-shaped structure with a through-hole design that runs from top to bottom. This through-hole closely cooperates with the core 2.2 to ensure that the core remains stable during the tableting process. A core stop 2.3 is provided below the through-hole. The function of this stop 2.3 is to lower the core 2.2 and prevent it from falling out of the lower part of the outer mold 2.1 due to gravity or other external forces. The stop 2.3 not only ensures the safety and stability of the core during operation, but also effectively prevents the core from accidentally falling off, thereby increasing the operational reliability of the equipment. A stop 2.4 is provided on the outer side of the upper end of the outer mold 2.1. When in use, the stopper 2.4 is used to precisely cooperate with the mold bracket of the mold shifting device, can maintain a stable posture, and will not be displaced by external forces, thereby improving the accuracy and consistency of the powder material molding operation.

[0026] In the above embodiment, the tablet pressing device 3 includes a bottom plate 3.1, a top plate 3.2, a connecting member 3.3 and a pressing drive member 3.4.

[0027] The bottom plate 3.1 is fixed to the frame 1, providing a stable support base for the entire tableting device. The compacting drive 3.4 is installed on the bottom plate 3.1 and is responsible for providing the required vertical pressure for the tableting process. The bottom plate 3.1 and the top plate 3.2 are arranged parallel to each other to form a parallel and stable structure to ensure uniform force transmission during the tableting process. The bottom plate 3.1 and the top plate 3.2 are connected by a plurality of connectors 3.3, which not only play a fixing role, but also provide additional support for the stability of the top plate 3.2, preventing structural deformation or displacement caused by uneven pressure during the powder material forming process.

[0028] An upper pressing head 3.5 is provided below the top plate 3.2, and the bottom surface of the upper pressing head 3.5 is arranged parallel to the bottom plate 3.1 to ensure that the pressure applied during tableting is evenly distributed on the tableting mold 2, ensuring the consistency and reliability of the powder material molding quality.

[0029] The pressing drive member 3.4 is provided with a pressing rod 3.6, which is arranged at the output end of the pressing drive member 3.4 to press the powder sample in the tablet pressing mold 2 under the drive of the pressing drive member 3.4.

[0030] The pressure rod 3.6 is also provided with a mold closing spring 3.7. The mold closing spring 3.7 provides auxiliary pressure during the tableting process to ensure that when the pressing drive is in operation, pressure can be applied to the outer mold 2.1 smoothly and evenly, thereby avoiding the tableting effect being affected by instantaneous pressure fluctuations.

[0031] In the above embodiment, the compacting drive 3.4 can be powered by various sources, including electric cylinders, hydraulic cylinders, pneumatic cylinders, slider-crank mechanisms, or cam mechanisms, depending on specific application requirements. This diverse power selection allows the tableting device to be more adaptable, meeting varying tableting intensity and speed requirements, ensuring optimal tableting results under a variety of process conditions.

[0032] To further enhance the precision and controllability of the tableting process, a force sensor 3.8 is installed between the upper pressing head 3.5 and the top plate 3.2. This sensor monitors the pressure applied to the tableting die in real time, ensuring that each step of the powdered material forming process remains within the optimal pressure range. This improves the precision and consistency of powdered material forming and effectively avoids tableting defects caused by excessive or insufficient pressure.

[0033] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
