[0028] Existing extrusion tableting devices are difficult to adjust in terms of extrusion thickness. However, different applications and different powders have different requirements. Companies using existing technology need to use multiple tableting devices of different sizes and thicknesses, resulting in significant space and equipment costs, thus increasing production costs for small and medium-sized enterprises. This invention, a powder extrusion tableting device, effectively solves this problem. The device includes a conveyor table 1 and a discharge machine 2 mounted on the conveyor table 1. The discharge machine 2 is equipped with a discharge pipe and a discharge mold 3. A tableting device is also mounted on the conveyor table 1.

The pushing component includes a pushing cylinder 4 mounted on the conveyor table 1, and the pressing mold 6 is detachably connected to the pushing cylinder 4.

[0029] In practical use, existing extrusion tableting devices are difficult to adjust in terms of extrusion thickness, requiring companies to use multiple tableting devices of different sizes and thicknesses. This not only occupies a lot of space but also increases equipment costs. However, the plastic powder extrusion tableting device of this invention, by setting up a detachable pressing mold 6 and a pushing cylinder 4, can easily adjust the extrusion thickness to meet the needs of different applications, reducing the company's equipment investment and space occupation.

The pushing component includes a pushing cylinder 4 mounted on the conveyor table 1, and the pressing mold 6 is detachably connected to the pushing cylinder 4. With this structural design, the discharge machine 2 can extrude plastic powder into sheets. The tableting device presses the extruded plastic powder into sheets through the pushing component and the pressing mold 6.

Compared with the prior art, the fixing plate 9 of this application can ensure the stable installation of the pressing mold 6 and avoid loosening caused by vibration or other external forces. The introduction of the telescopic rod 5 makes the height and angle adjustment of the pressing die 6 more convenient, enabling it to quickly adapt to the tableting requirements of different thicknesses, thereby improving production efficiency and product quality. Therefore, this application has significant advantages in improving the stability and adaptability of extrusion tableting devices.

[0035] The spring 12 between the connecting rod 8 and the fixing block 10 can be a compression spring 12.

At the same time, lubricating material can be added to the sliding structure to reduce friction. The fixing buckle 7 can be made of metal or high-strength plastic, and its internal through groove can be designed to match the size of the connecting rod 8 to ensure good fit after insertion. In addition, the insertion between the fixing buckle 7 and the fixing plate 9 can be achieved by snap-fit, thread, or other detachable connection methods.

[0036] This application achieves a stable connection and elastic adjustment between the fixed plate 9 and the pressing mold 6 by setting a connecting rod 8 and a fixing block 10 connected by a spring 12 on the fixed plate 9, and a fixing buckle 7 and a through groove on the pressing mold 6. Compared with the prior art, this technical solution not only improves the stability of the connection, but also adapts to the needs of different thicknesses of plastic powder tablets through elastic adjustment, avoiding the problem of needing to change different equipment in traditional technology, thereby reducing equipment costs and space occupation.

The groove 11 can be designed as circular, elliptical, or other shapes suitable for the movement of the spring 12, and can be adjusted according to the length and diameter of the spring 12. In addition, the depth and width of the groove 11 can also be optimized according to the elasticity of the spring 12 and usage requirements to provide optimal performance. Thus, by providing a groove 11 inside the fixing block 10, this application significantly increases the movement space of the spring 12, providing a more efficient and flexible solution compared to the prior art.
