Description

Technical Field

[0001] The invention relates to the technical field of tobacco production equipment, in particular to an automatic cleaning device for a tobacco leaf vacuum rehumidification turnover box. Background Art

[0002] After vacuum rehumidification, the tobacco flakes are turned over by the box-turning feeder. During the turning process, the flakes in the box cannot be completely dumped out, and some flakes will always remain at the bottom of the box. If the flakes remaining at the bottom of the box are not cleaned in time, they will re-enter the vacuum rehumidification machine and then undergo the second and third rehumidification. In this way, the remaining flakes adhere to the bottom of the box for a long time. After multiple rehumidifications, the moisture accumulates too much, causing the remaining flakes to form water-stained tobacco leaves. With the operation of the box, the water-stained tobacco leaves may fall at any time and mix into the normal tobacco leaves, and be mistaken for normal tobacco leaves and continue to be produced, causing the moisture content of the normal tobacco leaves to fluctuate, seriously affecting the product quality.

[0003] In order to clean the leaves at the bottom of the turnover box, the on-site operators need to manually clean each turnover box every day. Since there are more than 60 turnover boxes in the tobacco production line, a large number of turnover boxes waiting for manual processing consumes a huge amount of labor; and due to such a large workload, the labor intensity of the operators is greatly increased.

The box-pushing mechanism 8 includes mounting blocks 801, and the mounting blocks 801 are provided in two groups and are respectively fixedly installed on the outside of the drying table 109. A fifth screw rod 802 is rotatably connected between the two groups of mounting blocks 801, and a box-pushing plate 804 is threadedly connected to the outer surface of the fifth screw rod 802. The box-pushing plate 804 is slidably connected to the outer surface of the fixing rod 803, and the two ends of the fixing rod 803 are respectively fixedly connected to the inner sides of the two groups of mounting blocks 801.

[0069] Specifically, in this solution, the working principle of the box pushing mechanism 8 is as follows: Since two groups of drying tables 109 are provided, the fifth screw rod 802 is driven to rotate by the motor on the outside of one group of mounting blocks 801, so that the box pushing plate 804 slides along the outer surface of the fixed rod 803, so that the box pushing plate 804 can push the turnover box to the drying tables 109 on both sides.

[0070] The working principle and use process of this device are as follows: the turnover box is transported by the conveyor 101, and when the turnover box moves to the position of the fixed frame 102, the turnover box is lifted up by the lifting mechanism 7, and then the turnover box is clamped and fixed by the cooperation of the lifting mechanism 2, the second telescopic mechanism 3 and the clamping mechanism 4, and then the turnover box is driven to rotate so that the turnover box is in a horizontal state with the opening facing the right, and then the inner wall of the turnover box is cleaned by the cooperation of the first telescopic mechanism 5 and the cleaning mechanism 6, and the dust and residual smoke inside and outside the turnover box are removed. The leaves and other dirt are removed conveniently and quickly; the cleaned turnover box is reset to the conveyor 101 to continue to be transported, and when it moves to the drying table 109, the turnover box is lifted up again by the lifting mechanism 7, and then the turnover box is pushed to the drying table 109 by the pushing box mechanism 8, and then the inside of the turnover box is dried by the drying mechanism 9. The above operation process does not require manual operation, and realizes automatic cleaning and drying, so that the turnover box can be quickly put into use in the production line, which is convenient and fast, improves the cleaning efficiency, and meets the needs of the staff.
