Technical Field
[0001] The utility model relates to the technical field of health care product production, in particular to a tablet press. Background Art
[0002] Health care products are a popular term for health foods. Health foods have the common characteristics of general foods and can regulate the functions of the human body. Health foods can not only prevent diseases and improve immunity, but also supplement body nutrition. When producing health care products, a tablet press is needed to press the powder into tablets for patients to take. The working process of the existing tablet press can be divided into the following steps: the punch of the lower punch extends from the lower end of the middle die hole into the middle die hole to seal the bottom of the middle die hole; the powder is filled into the middle die hole by using a feeder; the punch of the upper punch falls from the upper end of the middle die hole into the middle die hole and moves down a certain distance to press the powder into tablets; the upper punch lifts the hole, and the lower punch rises to push the tablet out of the middle die hole to complete a tablet pressing process; the lower punch drops to its original position to prepare for the next filling. Among them, the structures of the upper punch and the lower punch are similar, and they are both controlled by the oil cylinder and can slide up and down in the middle die hole.
[0003] Health care tablets have different dosage requirements. Large dosage adjustments are achieved by selecting dies with different punch diameters. For example, the GZP16 high-speed tablet press produced by Beijing Hanlin Aerospace Technology Development Co., Ltd. has punches with diameters of 19 mm, 17 mm, 15 mm, 13 mm, 11 mm, 9 mm, etc. After selecting the die size, small dosage adjustments are made by adjusting the depth of the lower punch extending into the middle die hole, thereby changing the actual length of the middle die hole after the bottom is sealed and adjusting the filling volume of the powder in the middle die hole. Therefore, the tablet press should have a mechanism for adjusting the depth of the lower punch extending into the middle die hole to meet the requirements of dosage fine-tuning. Since the stroke adjustment accuracy of the oil cylinder is very low and cannot meet the tableting accuracy requirements, the current method is to place an adjustment block between the oil cylinder and the lower punch. Different tablets need to be equipped with adjustment blocks of different thicknesses. The adjusted thickness must be determined by grinding after several test presses. Tablets of different specifications need to be equipped with corresponding adjustment blocks. Although it has the function of fine-tuning the dosage, a tablet press needs to be equipped with several auxiliary adjustment blocks, which is inconvenient to use. It is also easy to cause batches of products to be scrapped due to the wrong use of the adjustment block. Summary of the invention
[0004] The utility model solves the problem that the existing tablet press in the prior art is inconvenient in micro-adjustment, and proposes a tablet press with simple structure and easy adjustment, which can conveniently perform micro-adjustment of dosage on the tablet press.
