Reasonable bottle cap production line

A good bottle cap comes from a stable production process. The stable production process mainly depends on several aspects: including good-performance machines and reliable molds, as well as scientific and reasonable molding processes. In addition to this, many people may often overlook an original influencing factor, that is, whether the design of the bottle cap production line is reasonable. In other words, to produce good bottle caps, we must first design a scientific and reasonable bottle cap production line.

For example, the bottle cap from the cap compression molding machine process directly enters the ring cutting machine without any buffer bin in the middle. The cutting machine pauses for a few minutes and the bottle caps made by the capping machine are forced to pile up nowhere. Use manual capping. In some production lines, the post-process speed is much faster than the pre-process, which causes the fast machine to wait for the bottle cap and always open and stop, which will cause unstable product quality.

Take the typical 1881 single-piece anti-theft bottle cap as an example to discuss how to rationalize this bottle cap production line. This bottle cap (The Coca-Cola Company first implemented the 1881 bottle mouth standard in China, and the application of single-piece caps and 1881 bottle caps has gradually increased.) It needs to undergo four processes: compression molding, hemming, ring cutting, and top printing. This production line is designed according to the standard of 1881 carbonated beverage caps. Two capping machines produce bottle caps, followed by a hemming and thread cutting machine, and It consists of one printing machine. The speed of each capping machine is 800pcs / minute, so the production speed of the whole line is 1600pcs / minute and the speed is 9600pcs / hour. It belongs to the traditional high-speed bottle cap production line.

First of all, from the feeding system, usually the raw material of the bottle cap is composed of resin and masterbatch. The raw material of the bottle cap with special requirements may be mixed by two different resins in a prescribed ratio, and then add the masterbatch and slip agent Auxiliary formulas. Generally, small bottle cap factories rely on manual weighing of color masterbatch and raw materials and then manual mixing, which will bring about the problem of unstable ratio and bury hidden dangers for the problem of bottle cap color deviation. The medium and large-scale bottle cap factories all use automatic metering machines, such as Matsui metering and mixing devices, and there are also many domestic metering and mixing systems. Using an automatic metering machine, the raw material ratio will be strictly in accordance with the set value to avoid human deviations. Another practical problem is that it is basically impossible for the high-speed bottle cap production line to rely on manual mixing. Only small factories will reduce costs. Artificial mixing.

After the bottle cap comes out of the compression molding machine, the temperature is usually very high. If the cap is slightly squeezed when the cap is transported at this time, the cap will be deformed. The deformed cap will bring about the folding of the rear line and the cutting ring. Adverse effects. At the same time, many customers will be highly sensitive to deformed bottle caps. Deformation of bottle caps is often one of the defects with a high complaint rate. Therefore, after the bottle cap comes out of the capping machine, especially the cap with a thick top similar to 1810, 1881, 38mm, try not to enter the folding machine immediately, you should use a cooling belt or a climbing type cap feeder, or a roller type The cooler allows the bottle cap to cool down during transportation.

In addition to this, there is another and very good cooling method, which is the use of a blower. The bottle cap comes out of the capping machine and directly enters the blower. The bottle cap runs in the conveying pipe under the action of wind, and the effect of wind can fully cool down. The bottle cap can achieve the purpose of conveying the bottle cap.
