Description

Technical Field

[0001] This utility model relates to the field of tablet press technology, and more specifically to an automatic tablet press mold for pharmaceutical use. Background Technology

[0002] A tablet press is a machine that compresses dry granular or powdery materials into tablets using a mold. Tablet presses are widely used in the pharmaceutical, chemical, and health product industries.

[0003] Traditional tablet press molds mostly use a fixed cavity structure, requiring manual intervention in processes such as raw material filling, mold transfer, and demolding. This makes it impossible to achieve continuous automated production, resulting in low production efficiency. In addition, uneven manual demolding force can easily cause tablets to stick or break. Furthermore, the dispersed layout of multiple process equipment leads to poor production line coordination and a large footprint, making it difficult to meet the needs of modern pharmaceutical industry for efficient and intensive production.

A coil spring 85 is sleeved on one end of the rotating shaft 83.

[0024] The working principle of this utility model:

[0025] The top of the support plate 2 is provided with three zones: the feeding zone at the bottom of the discharge head 5, the pressing zone at the bottom of the extrusion plate 63, and the demolding zone at the top of the demolding handle 76.

[0026] The servo motor 4 drives the rotating plate 3 to rotate intermittently around the output shaft of the servo motor 4, so that the three mold cavities 31 shuttle between the feeding area, the pressing area and the demolding area in sequence.

[0027] The discharge head 5 feeds raw material into the mold cavity 31 at the material feeding area. The output end of the cylinder 61 shortens, causing the positioning bar 62, rack 64 and extrusion plate 63 to move vertically downward as a whole. The rack 64 drives the rotating rod 71 to rotate around its own axis through the flat gear 711. The rotating rod 71 rotates and drives the threaded rod 74 to rotate synchronously around its own axis through the first bevel gear 712 and the second bevel gear 741. The threaded rod 74 rotates and drives the motion frame 75 and the demolding handle 76 to move vertically upward synchronously as a whole.

[0028] During this process, the extrusion plate 63 enters the mold cavity 31 in the pressing area and presses the raw material into tablets. The demolding handle 76 pushes the tablets in the mold cavity 31 in the demolding area upward. The pushed tablets squeeze the guide strip 84, causing the guide strip 84 to rotate upward around the axis of the rotating shaft 83. The coil spring 85 is pulled by the rotating shaft 83 and its elasticity increases. After the tablets pass through the two guide strips 84, the output end of the cylinder 61 shortens downward, causing the demolding handle 76 to return to its initial position. The elasticity of the coil spring 85 drives the guide strip 84 back to its initial position. Under its own gravity, the tablets slide down along the guide strip 84 and the slide rail 82 and are output outward, entering the subsequent production and processing equipment.

[0029] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
