Mixed driven cover turning apparatus suitable for different bottle mouth threads

Abstract

The present invention belongs to the field of food packing machine technology, and is especially one kind of mixed driven cover turning apparatus suitable for different PET bottle mouth threads. The mixed driven cover turning apparatus includes cam, push rod, planetary wheels, cover turning heads, asymmetrical motor for reducer, servo motor, central wheel, spindle and turntable. The turntable driven with the asymmetrical motor and its cover turning heads via the reducer rotates around the spindle, the planetary wheels rotate to provide power for the cover turning heads, the central wheel meshed to the planetary wheels is driven with the servo motor, and the cover turning heads are connected to the cam through the push rod to rotate, revolve and vertically reciprocate simultaneously. For sealing bottle of different threads, the rotation speed and rotation direction of the servo motor are regulated.

Description

technical field [0001] The invention relates to equipment in the technical field of food packaging machinery, in particular to a hybrid drive capping equipment suitable for the screw threads of different filling bottles (hereinafter referred to as PET bottles). Background technique [0002] At present, the capping machines on the advanced beverage filling production lines at home and abroad are mainly the capping machines of the rotary tower type. The patents of this type of capping machines are basically owned by foreign countries, and the domestic design and production are mainly based on foreign ones. Its structure is mainly that there are multiple capping heads revolving around the main shaft. During the revolving process, the capping heads must move up and down to complete the actions of cap removal, cap screwing, and bottle separation. The movement of the capping head in the vertical direction is determined by the curve of the fixed cam. The rotation of the capping hea...

Problems solved by technology

In this case, it is obvious that the capping machine of the first method is no longer applicable.

Although the second type of capping machine can control the rotating speed of the capping head, since the motor is installed on each capping head, not only the volume of the machine is greatly increased, but also because multiple motors work on the rotary table, the wiring scheme and power And the transmission of control signals is also very difficult, so the cost is very expensive, the cost performance is not high, and it is not suitable for the development needs of my country's current beverage filling industry

However, this capping machine can only realize three-stage variable speed transmission, so it can only basically meet the requirements of three different bottle threads. The capping equipment for bottle caps has become out of applicability and flexibility

Moreover, this mechanical variable transmission scheme is inconvenient to operate (control). On the one hand, it increases the cost of machines and labor, and on the other hand, it brings problems to the hygiene and safety of products. The requirements for speed and production efficiency are constantly increasing, and the efficiency, reliability and precision of this mechanical variable speed capping equipment are far from meeting the requirements.
