Jeepine plastic cap compression moulding Original
High quality plastic caps is from stable production process, stable production process mainly depends on several aspects: good performance cap compression moulding machine, precise and reliable plastic cap mould, scientific and reasonable forming process, in addition to this, many people tend to neglect the influence factors of one of the most primitive, it's plastic cap compression molding production line design is reasonable or not, that is, to produce the high quality plastic cap, the first thing to design a scientific and reasonable cap production line.
Set foot on the pearl river delta, Yangtze river delta, such as manufacturing industry developed regions, found a lot of plastic closure compression moulding production line for middle and small plastic cap factory structure is not reasonable, which always plastic cap factory regularly for the customer complaints and returns, rework the toes, if customer complaints cap deformation is today, the customer reflect cap leak leakage tomorrow, the next day and the bottle cap is broken rings bad or all kinds of high tilt cover ratio higher, cap stand or fall of quality, really tired.In fact, their equipment quality is not poor, the performance is also relatively stable, the quality management is not very bad, why the bottle cap that makes comes is not satisfactory?The answer may be that there is a lot to do with the design of the bottle cap compression moulding production line.
For example, the bottle cap directly goes into the cap slitting machine after the cap compression moulding process , no surge bin among them,cap slitting machine a slight pause for a few minutes, cap compression moulding machine to cap is piled up and was forced to use artificial to cover, and some of the cap compression moulding production line after the process speed is faster than before the process is too much, again lead to a faster machine to wait for cap and always starting and stopping, so more can cause unstable product quality.
Below, we in the most typical of PCO 1881 single chip anti-theft caps as an example to discuss how to turn the bottle cap compression molding production line rationalization, the cap need after molding, folding, cap slitting, the top four printing process, the production line was built according to carbonated drinks for coke PCO 1881 standard design, two cap compression moulding machine production cap and follow-up by a cap folding and tangent machine, and a printing press, each gland machine speed is 800 PCS/min, so the whole line production speed is 1600 PCS/min, the speed of 9600 PCS/hour, belong to the traditional sense of the cap compression moulding production line at a high speed.
First from feeding system, usually cap materials composed of resin mixed with pigment mixing, the plastic caps have special requirements of raw materials may be composed of two different kinds of resin in accordance with the provisions, mixing ratio, then add the masterbatch and smooth agent such as auxiliary formula.General small cap making factory relied on artificial weighing masterbatch and raw materials and then mixed after use, it will bring the problem of ratio, a dangerous precedent for the cap color deviation problem.Medium and large bottling plants are using automatic metering machines, such as matsui metering mixing devices, and many domestic metering and mixing systems.Using automatic weighing machine, ratio of raw material will be in strict accordance with the set value, avoid artificial deviation, there is a real problem is that the cap production line rely on artificial mixing is basic is impossible, only small factories to reduce costs and artificial mixing materials.
the plastic cap temperature is usually very high after the high speed cap compression moulding process, if the time in the bottle conveying time squeeze the bottle slightly will deformation, deformation of the cap on the line after folding and cutting ring brings bad influence, at the same time, many customers will higher sensitivity to deformation cap, cap deformation is often measured one of high defect.So after cap out of the capping machine, especially similar to PCO 1810,1881, 38 mm thick large cap, it is best not to immediately enter the folding machine, should use type send cooling belt or waterfall unscrambler, or rotary cooler, resulting in the cooling cap in the process of conveying.But there's another cooling way also is very good, is to use the air blower, cap directly into the blower after out of the cap compression moulding machine, bottle caps under the action of wind, running in the pipeline, the effect of the wind can be fully cooling cap and can achieve the aim of the cap again.
Plastic cap cooler
Many people go to a few large plastic cap making factory visit may find that their cap compression molding production lines often have several transit warehouse, basically the caps with the corresponding to each working procedure before and after the transit warehouse, one could feel these interim positions do not need to, take a place and increase costs.In fact, the existence of these transit warehouses is meaningful and has great help to the continuous stability of the bottle cap.Capping machine cap out through pipelines into the interim positions before flanging, the number of interim positions for two, each gland machine corresponding to a transit warehouse, every interim storage volume of 2 m3, basic can accommodate the output of capping machine for 1 hour. cap compression molding corresponding to each independent interim positions, rather than focus on a major transit warehouse, the purpose is if one machine in the process of production of a problem can timely isolation cap, lower spread to another one capping machine cap risk.Transit warehouse design also has certain skills, is not simply a iron box, you can see, cant warehouse inside will increase a few, its purpose is to avoid deformation of pile cap direct pressure.The outside of the transit warehouse is made of transparent acrylic sheets, which can be seen from the outside and can be seen at any time.When the lid comes out, it enters a serpentine track, which ACTS as a buffer.And holidays of the railway station, bus station stops before many turn to turn to the iron grille, although a few meters distance away from the romantic, but everyone will orbit several times to station, which can guarantee a good pit stop order.S orbit similar role, is to make the cap one by one against the stable and smooth access to folding machine, to ensure the good folding process, if the lack of the s-shaped rail, cap from waterfall unscrambler track down directly into the star wheel of the cap folding machine rotary table, follow closely not between cap and bottle caps, it's easy to have a bad card cover or folding and cutting ring.The folding and cutting ring is a one-piece machine, which means that the bottle cap after the folding will be cut in the order of the star wheel.The folding and cutting ring adopt gear linkage, and the rotation speed of the rotary disc is the same.The cap folding and cap slitting adopt an all-in-one machine, which can effectively reduce the floor space of the machine and save some auxiliary cover and transit warehouse.
After cap folding and slitting out of the bottle cap after online inspection system after entering the cap cooler to the transit warehouse before printing, this interim positions about can be close to 2 hours of production capacity, printing the person all know, higher chance of cap printer need human intervention, such as production after a period of time may be slowly printing fuzzy or partial light, then need downtime for artificial clean the plate and strip, or on fine-tuning the ink amount, interim positions before printing of larger capacity of the design is very reasonable.The speed of the printing press is 1900pcs/ min, and the speed of the cutting edge is about 200pcs/ min, and the reason is that the printing presses need to stop for more time and more times.
On the cap in the printer through flame processing, printing ink, UV light curing after three steps out is the finished cap, press outlet set up counters, cap will enter the automatic packing system, a box full of carton will automatically move forward, after the next empty containers will be moved to the cover.
Cap compression moulding machine, in general, we usually don't stop, unless the abnormal situation, frilled edge cutting ring can be allowed to stop once in a while, a class about 2 to 3 times, were relatively more printing machine downtime.The process of each process in order to use reasonable pull speed difference to ensure that the bottle cap is stable and continuous production.
