Blister packaging material printing ink Drug used for blow-cover packaging ink can be divided into two categories: one is the distribution of gliadin polyamide ink printing materials with good adhesion, gloss, wear resistance, good solvent, mainly used in plastic printing, its thermal stability can also meet the needs of aluminum printing, is the majority of medical aluminum foil printing materials. The problem with this type of ink is that ink stripping occurs when large area surface of aluminum foil is printed. Secondly, it is a kind of vinyl chloride, vinyl acetate copolymer resin and acrylic resin as the main components of special aluminum foil ink. This is a newly developed rotary gravure printing ink with bright color, high concentration, special adhesion to aluminum foil, good transparency, good reproducibility of aluminum foil metal luster, etc. But because it is a gravure printing ink, the solvent is volatile. PTP aluminum foil used in medical printing tends to produce d

Pressing machine needs to pay attention to the problem The working process of the press is to press the raw material into irregular or regular shape, of course, not all the press are in the shape of powder particles. Due to the particularity of powder particles, there are many points to be paid attention to in the process of processing. The machine needs a stable environment in the process of pressing powder granule raw materials to provide basic flat ground fixation under the most basic conditions. According to the process of the parts of the comparison, choose the appropriate type of mold. There is a certain relation between the size of mold and the granularity of raw material. As the stamping object of the whole pressing machine is powdery material, try to avoid mixing other types of waste. Dust has always been a domestic and most of the imported tablet press must pay attention to the problem, so dust pollution and removal is also a problem. The main products are g

The feeding operation of the capsule filling machine Start the main motor, press the start switch of the main motor, the indicator light is on, and the main motor runs.

The frequency converter displays the corresponding frequency or the number of particles filled in the capsule per minute. Manual feed control, press manual feed switch, indicator light is on, feed

Punch processing of the tablet press If the punch head is broken or the punch tail is broken, it may be due to improper heat treatment of the mold, its own damage and cracks have not been carefully checked, and it cannot bear the excessive pressure or pressure of the press. If the fatigue limit of the mold itself is exceeded, it may lead to fracture. Improve the heat treatment method of punch, strengthen the stamping quality control, adjust the pressure, pay attention to the visual inspection of tablet. At the same time, the service life of the mold can not be unlimited, generally in 30 million to 50 million pieces or so, must be scrapped, have to replace the new, old, easy to wear tail mold can not be used. The upper pulse is easy to hit the feeder, and the lower pulse is easy to hit the orbit. If a fault occurs, damage to the feeder or the discharge track is prone to greater problems. So often check the mold, replace the old mold in time. In addition, shock absorbers can be add

Moisture resistance of blister packing Aluminum-plastic blister board may now common drugs, generally on the side face of aluminum-plastic blister plate set several drugs for hosting the bubble shell holes, aluminum-plastic plate heat sealing joint through a hole in the blister, but this kind of packing model for easy to moisture absorption of the drug to seal tightly enough to easily make drug moisture absorption metamorphism, sealing material in the resistance movement or contact distance though close enough, also can make drug moisture absorption metamorphism. The Chinese patent waterproof plastic blister plate covers the third layer of the material on the aluminum plastic label, which has a waterproof layer to prevent moisture and also needs to protect the medicine; Packaging can protect water for general drugs, but the absorption, storage or transportation of special drugs can not achieve good results if the environment humidity is high, product quality can not be guaranteed fo

Improvement of tablet press Because the machine wheel has a milling key on the upstroke, and to press the up guide key on the upstroke rod. When used, the up-punch rod with the guide key and a pair of keyways with the direction key must be loaded into the punch hole respectively, so that the up-punch rod can only move up and down, and cannot rotate in the hole. When installing the special-shaped middle die, it only needs to move the middle die up and down to offset the hole, and insert the middle die in the same shape. The head does not leave the middle mould during the round drilling of the downpunch rod. The tool rod drilled behind the head is inserted and assembled in the hole. The function of the borehole toolbar is specified specifically, that is, the borehole is only up and down, there is no other key borehole to install guidance, and the downhole does not need to be milling groove. In this way, the press can be pressed under a variety of profiles, up and down the impact ba
