Defoaming device before bottled liquid light inspection and defoaming method of defoaming device

Abstract

The invention provides a defoaming device before bottle liquid light inspection and a defoaming method of the defoaming device. The defoaming device comprises a rack, a liquid containing container, a conveying device and an ultrasonic device, the liquid containing container is located on the upper portion of the rack and filled with a liquid medium, the conveying device and the ultrasonic device are both partially arranged in the liquid containing container, and the conveying device does not make contact with the ultrasonic device; the conveying device can convey bottles and enable the bottles to be immersed in the liquid medium. The defoaming method comprises the steps that the ultrasonic device is started, and meanwhile the conveying device is started; filled bottles enter the conveying device, the conveying device lowers the bottles to below the liquid level of the liquid medium, the ultrasonic device sends out an ultrasonic oscillation signal to remove liquid bubbles in the bottles, and the conveying device conveys the bottles to the light inspection process. The defoaming device can thoroughly remove the bubbles in the bottle liquid and can be arranged on a production line without separately occupying a production space.

Description

technical field [0001] The invention relates to a defoaming device and a defoaming method for bottled liquid before light inspection. Background technique [0002] Before the light inspection of bottled liquid products (such as injections, liquor, beer, mineral water, etc.), in order to achieve the ideal detection effect and reduce the influence of the bubbles of the product to be tested on the test results, it is generally necessary to detect the bubbles produced by the liquid to be tested. Perform elimination processing. At present, the static method, the high-speed rotation method and the addition of serpentine buffer are mainly used. These methods have the following deficiencies: [0003] 1) Static method: place the detected object statically on the stockpiling buffer platform, and after a period of time, the air bubbles will disappear naturally. This method can effectively eliminate the air bubbles when the waiting time is long enough, but At the same time, the bottle...

Problems solved by technology

[0003] 1) Static method: place the detected object statically on the stockpiling buffer platform, and after a period of time, the air bubbles will disappear naturally. This method can effectively eliminate the air bubbles when the waiting time is long enough, but At the same time, the bottle feeding time of the equipment is delayed, and a large space is needed to store the static bottles, which is greatly restricted in the case of assembly line production, especially in the case of high-speed assembly lines; The bubble effect is not good; in addition, it is easily affected by the ambient temperature, and the length of time for bubble elimination may change with temperature changes, and there is great uncertainty;

[0004] 2) High-speed rotation method: the bottle to be inspected is clamped by the manipulator, and then the high-speed selection is performed at a speed higher than 1000 rpm, and the centrifugal force generated by the rotation is used to break away and burst the bubbles. This method is suitable for small bottles (less than 20ml) ) can eliminate most of the air bubbles, and has a better effect on the air bubbles adhering to the bottle wall, but there are also some problems at the same time: a larger bottle type (above 20ml) requires a higher speed, which is harmful to the manipulator and the rotating device. The requirements for accuracy and consistency of the bottle shape of the bottle to be inspected are very high. If the rotation is eccentric, the liquid in the bottle will be unevenly stressed, causing the liquid level to oscillate and produce bubbles; in the current domestic situation, it is necessary to ensure that the bottle to be inspected The consistency is unrealistic, and the improvement of the precision of the manipulator and the rotating device also brings about a substantial increase in manufacturing costs;

[0005] 3) Increase the serpentine buffer: Add an S-shaped buffer conveyor belt at the front of the light inspection machine, similar to method 1), mainly to solve the bubble problem by prolonging the time to let the bubble disappear naturally without affecting the speed of the assembly line. The method solves the problem of method 1) to a certain extent that a large space is required to store the static bottles. Since the bottles to be inspected are always in motion, theoretically as long as the S line is long enough, the production speed can also meet the requirements; but this The manufacturing cost of the serpentine buffer transmission belt required by this method is relatively expensive, and the manufacturing requirements are also relatively high, especially in the place where the turning is excessive, the collision is not allowed to generate air bubbles again, and this method also has the problems in method 1), such as The effect of air bubble treatment on the bottle wall is not very good, and it is easily affected by the ambient temperature, etc.
