1) Bottle washing and filling part structure and its function

The rinsed bottle is exported from the flushing section to the filling section through the bottle dial wheel. The bottle that enters the filling section is lifted by the bottle holder, and is raised, held and lowered by the lifting mechanism under the action of the cylinder. Top-loading filling valve is filled by closed filling method. The adjustment of output is controlled by frequency converter. High-speed filling valve is used to control the liquid level accurately and the error is small

a. Filling cylinder: The filling cylinder is a special container used to hold materials and ensure the constant pressure and stable operation of the entire filling system. The material enters the liquid tank through the lower distributor and is sent to the filling valve. The liquid level of the cylinder is controlled by the level probe through the backup pressure and high pressure, so as to control the liquid level. The CO2 is sent to the wine tank from the high-pressure and backup pressure pipes on the upper distributor. If the pressure in the filling cylinder exceeds the limit value of the safety valve, the diaphragm on the safety valve will automatically open to discharge the pressure in the cylinder to the outside of the cylinder, thus acting as a safety precaution. This machine is specially equipped with a CIP cleaning function tube, as long as the cleaning valve is installed on the canned valve, CIP cleaning can be performed. All the above-mentioned CO2 and compressed air pipes are connected to the upper distributor, and are connected to the filling cylinder and the lifting cylinder through their respective connecting pipes. Material pipe and CIP pipe are transported by independent pipelines. The filling cylinder is equipped with a pressure gauge and a temperature gauge, and the filling status can be checked at any time.

b. Filling valve: High-precision spring-type mechanical filling valve is composed of three parts: gas injection valve, liquid valve and exhaust valve. The filling valve is located in the filling cylinder and is always closed under the action of the cylinder pressure. The working process is as follows: (1) The bottle is lifted by the lifting cylinder. Under the action of the elastic force of the cylinder, the bottle mouth is tightly sealed with the bottle mouth gasket and the filling valve on the pre-cover device.

(2) After the bottle is measured by the "no bottle-no filling" mechanism, operate the valve stem fork to the injection position, and open the injection valve under reverse pressure. The gas in the filling cylinder is first injected into the bottle through the opening of the inflation valve stem, the inner hole of the stem of the liquid valve and the air pipe vent.

(3) When the pressure in the bottle equals the pressure of the filling cylinder, the valve stem opens under the action of the spring, and the liquid in the filling cylinder flows into the valve seat through the round hole in the spring sleeve, and then flows through the shunt installed on the return pipe. The umbrella flows into the bottle evenly along the inner wall of the bottle. When the liquid flows into the bottle, the air in the bottle goes back to the filling cylinder through the return pipe through the valve stem and the injection valve.

(4) The liquid continues to flow until the liquid level reaches the lower end of the return pipe to intercept the air circuit, and the liquid stops flowing. Replacement of return air pipes of different lengths can fill liquid levels of different heights.

(5) The valve closing device gradually rotates the operating valve stem to forcibly close the gas injection valve and the liquid valve.

(6) The valve stem of the exhaust valve is pushed by the exhaust cam, and the compressed gas in the upper part of the bottle is gradually released to the atmosphere, so that the pressure in the bottle is kept in communication with the outside world. Prevent the pressure in the bottle from foaming due to sudden pressure drop, which will cause the filling liquid level to be dissatisfied.

3)  Gland part structure and function

The capping plunger is rotated by a power belt. When the capping machine rotates once, each capping plunger will reciprocate up and down once. The cam controls the up and down movement of the gland plunger, and the cam is mounted on a fixed part of the upper part of the gland press. After the bottle has been transferred from the filling machine, a cap is fed into the cap container of the capping head by the cap feeding system. Under the action of the cam guide, the gland plunger descends to the bottle that has been erected on the lower platform, and then the capping operation is performed by the booster ring. The gland plunger located on the upper turning body of the gland machine moves accurately up and down along the gland cam of equal travel distance. work location:

In station I, the capping plunger has already been connected to the cap at its highest position. When the plunger is lowered, the bottle first contacts the cap, and the cap is taken into the capping mold by the cap-retracting rod.

In station II, as the cap-removal lever contacts the die guide of the small spring, the small pressure spring presses the lid, so that the sealing rubber pad of the lid is tightly pressed against the bottle mouth, ensuring the tightness after the capping.

In step III, when the gland plunger is further downward, the bottle and cap penetrate into the gland mold. At this time, the bottle cap is pressed, and the plunger plunger penetrates to a depth of about 8 mm (clamping stroke), and clamps the flange portion of the bottle mouth, and the tooth edge of the bottle cap is compressed.

In step IV, only the bottle used is 5-10mm higher than the minimum bottle, and the die guide slowly touches the pressure ring and contacts the large compression spring to provide the bottle compensation function.

In step V, when the capping plunger is subsequently moved upward, the spring guides the die to slide back, and at the same time, under the action of the rotation stop, the capping lever causes the capped bottle to be smoothly removed from the capping mold. Prolapse.

After receiving another bottle cap, the capping plunger is ready for the next capping process (step I).
