The filling machine is configured in the humid and acidic environment, and mainly runs in the high temperature climate in summer, it should be filled with lubricating oil and grease in the relevant parts according to the regulations, do the ventilation and drainage of the workshop as well as possible, and the equipment should be cleaned after work. Install the shield plate of the equipment to protect the transmission mechanism and pay attention to the safety of the body.
In the peak production season, after working continuously for a period of time (about 3 months), the worn O-rings and gaskets can be replaced, and the equipment needs to be overhauled once every 1 or 2 years.
2、Filling quantity adjustment
After filling, the liquid level in the bottle of beer, soft drinks, etc. is equally high. When filling, each filling head should be numbered, and the filling level height should be measured separately and recorded properly. If most of the tables do not meet the requirements, you can adjust the position of the inflatable touch block on the ring guide to change the time of equal pressure process; you can also adjust the position of the exhaust touch block to change the time of closing the liquid valve in the bottle by lowering the pressure in order to adjust the amount of liquid filling in the bottle. If it is found that the filling quantity of the filling head is unqualified, the opening of the exhaust needle valve on the side of the filling valve can be adjusted to change the speed and time of closing the valve with buckling pressure in the bottle, and if necessary, the extended length of the exhaust pipe in the center of the valve or the tension of the balance spring in the valve can be adjusted to close the liquid filling valve earlier or later when the pressure in the bottle changes.
The volume of liquid filling mainly depends on the liquid level of packaging container to quantify, and its quantification accuracy is influenced by the volume deviation of the container and the length of the filling exhaust pipe, such as dislocation of the exhaust pipe or unobstructed exhaust, obstruction of the irrigation channel or damage of the sealing gasket between the container mouth and the filling valve, all of which will affect the inaccurate quantification of the filling liquid level. For the filling of gas-containing liquid, there is also the problem of foaming back spray. If the pressure drops too fast or the impact of liquid flow is too violent when filling with gas-containing liquid, a large amount of foam will occur and plug the exhaust pipe, causing the filling liquid level to be insufficient, and in serious cases, a large amount of foam will be sprayed out when the container is separated from the filling head, causing the loss of liquid. Solution: ① Ensure the low temperature of the filling liquid and the flow rate of the conveying pipe is not too fast, so that the dissolved carbon dioxide can be kept as stable as possible; ② make sure the position of the filling touch block and the opening of the needle valve of air venting, so that before the container leaves the filling head, it will slowly vent out and lower the pressure, so as not to cause the phenomenon of reverse spraying.
Isobaric filling machine is filling the gas-containing drinks, equipment adjustment is not ideal will affect the filling effect. When analyzing the faults, it is necessary to distinguish between individual faults and repeated faults, occasional faults and continuous faults, so as to prescribe the right remedy and eliminate the faults. Table 3-2 lists the common faults and elimination methods of isopressure filling machine according to the practical experience.
