Description

Technical Field

[0001] The utility model relates to the technical field of tablet presses, in particular to a tablet press with adjustable thickness. Background Art

[0002] Tablet press is a kind of equipment widely used in pharmaceutical, food, chemical and other industries. It is mainly used to press powdered or granular raw materials into flake or block products. It fills the raw materials into the mold evenly through a series of mechanical movements and pressures, and compacts and solidifies the raw materials through pressure to finally form the required flake products. Tablet press can select different molds and parameter settings according to different raw material characteristics and processing requirements to produce products that meet the requirements.

[0003] Publication No. CN217862981U discloses a Chinese herbal medicine tablet press for convenient tablet discharging, comprising a bracket, a hydraulic cylinder, a positioning plate, an upper die and an ejection device; the ejection device comprises a base, an ejection column, a first rotating motor, a first screw rod, a first threaded sleeve, a lower die and a support assembly, the positioning plate and the upper die are driven to move up and down by the hydraulic cylinder, the lower die is provided with a plurality of grooves penetrating the lower die, the first rotating motor is driven to rotate the first screw rod, and then the threaded sleeve and the lower die are driven to move up and down, when pressing tablets, the lower die rises, so that the powder can enter the groove on the lower die, and then the hydraulic cylinder is started to drive the upper die to move downward, and the powder is pressed into tablets, after the pressing is completed, the first rotating motor drives the first screw rod to rotate, and then drives the lower die to descend, so that the ejection column ejects the tablets pressed inside the groove of the lower die, thereby achieving the purpose of convenient tablet discharging. Although the tablet press can use an ejector column to eject the tablets pressed inside the lower die groove to facilitate tablet discharge, the die of the tablet press is not easy to replace, and only tablets of the same thickness can be pressed. The tablet thickness cannot be adjusted according to different material properties and process requirements. The scope of application is small and needs to be improved. Utility Model Content
