Description

New blueberry automatic weighing packaging machine

technical field

The invention relates to the field of food packaging machinery, in particular to a novel automatic weighing and packaging machine for blueberries.

Background technique

The applicant has applied for and disclosed the invention patent "A blueberry automatic weighing and packaging machine (publication number: CN105151335A)", although it has better solved the problems of high labor cost, low efficiency and poor progress in the past blueberry weighing and packaging process. However, in the long-term use process, the applicant found that the current equipment still has some deficiencies and needs to be improved. The specific problems are as follows:

1. The main structure of the fruit setting mechanism includes a distribution conveyor belt, a distribution transmission motor and a linear vibrator. During actual use, the applicant found that controlling the number of blueberries dropped by the linear vibrator is not very accurate, and sometimes multiple blueberries will drop at the same time, resulting in overweight blueberries, which fails to achieve the purpose of accurately controlling the weight of blueberries.

2. The packaging box separator is a peel-off structure. The packaging boxes are stacked on the separator frame, and then the ejector rods on both sides move towards the direction of the packaging box at the same time, and the stacked packaging boxes are separated one by one. However, this separation structure has the following problems: the separation accuracy of the packaging box is poor, and the requirements for the packaging box are high. When two adjacent packaging boxes are stacked too tightly, it is not easy for the ejector to separate them, and a separation often occurs. Two packaging boxes are produced or the packaging boxes are not separated, which will affect the subsequent packaging work.

3. The slope of the fruit delivery mechanism can only be manually adjusted in a small range through the height adjustment mechanism, and the rear end of the fruit delivery mechanism is always higher than the front end, so that as long as there are blueberries on the fruit delivery mechanism, the blueberries will roll down to the vibration Institutional. However, after the packaging is completed, there may be remaining blueberries on the fruit delivery mechanism. At this time, the blueberries do not need to continue to roll down, and the current fruit delivery mechanism cannot prevent the blueberries from rolling down.

4. The fruit delivery belt of the fruit delivery mechanism only rotates back and forth driven by the fruit delivery motor. Since the fruit delivery belt is long and lacks support in the middle, it will rub against other mechanical structures when rotating, and the noise is relatively large.

5. After the blueberries fall into the weighing box, the weighing box is pulled back through the telescopic cylinder, so that the blueberries fall into the packaging box below. During the falling process of the blueberries, affected by factors such as mutual collision and inertia, the blueberries will scatter, and occasionally some blueberries will not fall into the packaging box, which will affect the accuracy of the packaging weight.

Therefore, the technical scheme of above-mentioned invention patent also needs further improvement.
