The development of Blister packaging PVC
Pharmaceutical packaging PVC board made from PVC resin, add a few auxiliary technology through extrusion processing method in the production of qualified drugs, as an independent aluminum-plastic packaging substrate, each piece of tablets and capsules independence, become the smallest unit of medical packaging, make drugs safe, accurate, because the processing method is simple, small investment, easy processing, reduce pharma pharmaceutical production costs, improve production efficiency.
Because vinylidene chloride polymer density, uniform structure, in high humidity environment will not leak, excellent water resistance, resistance to oil and solvent performance is poor, especially for oxygen in the air, water vapor and carbon dioxide has a high performance barrier. In addition, impact resistance, tensile strength, seal durability and other indicators can meet the special requirements of pharmaceutical packaging printing, the future devel
How should the problem of capsule filling machine be solved
Sometimes there are problems with the head and tail of the capsule. The problem of replacing the capsule and shell will be solved. Then examine the thimble to see if the height of the thimble needs to be adjusted. Sometimes you can also increase the stress area of the cap to solve the problem. Increasing the strength area of the capsule thickens the thimble. You can try to solve it.
Capsule splits, which are a very headache, are often found. You have to be careful. This usually happens for the following reasons.
1. Differences between the capsule itself, capsule cap and capsule body. The capsules need to be replaced.
2. Too much residual powder in the module. Modules need to be cleaned up.
3. When installing the module, the upper and lower modules are not aligned, please re-align the module. Until the debugging bar closes automatically.
4. In fact, it is also related to the size of the particles. I have not c
Note for single stamping machine
According to the friction lubrication, is to ensure that the machine running and prolong the service life of the important link, especially the rapid drying of major sports if lack of oil transfer cause damage and cannot be used, so the machine before use all the oil cup, add lubricating oil hole, the friction surface, idle machine to make all the friction surface coated in oil can be used. In the future, regular refueling every shift, but each refueling should not be excessive, so as not to spill the influence of cleaning, stained tablets. Each refueling location and the number of refueling should be planned. :
Check whether all screws are loose before each shift, and pay attention to them when working. Tighten immediately to avoid failure. Its main components are: upper punch fixing nut, middle punch fixing screw, lower punch fixing screw; Locking nut and locking screw; Clamping nut, tension fixing screw for central grinding machine. Before and
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. When the vacuum pump motor does not start or the machine opens the movable door, the main motor cannot start and can only be inching operation.
The engine is mainly suitable for movement when the switch is pressed on the main motor, the index finger is closely connected, that is to say, the main engine rules, the main motor is connected to the movement, the main motor stops rotating, the second time is pushed out before the main motor must be in continuous operation.
The speed is regulated by a frequency converter. After the main motor starts, press down the frequency converter to run from low speed to high speed. 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
