Description
Technical Field
[0001] The utility model relates to the technical field of tea packaging, in particular to an empty package detection mechanism for tea packaging transmission. Background Art
[0002] Tea is a common traditional drink in people's daily life, especially green tea, which maintains its bright green color and natural healthy ingredients and is deeply loved by the general public. The processing of green tea requires multiple important steps such as sun drying, shaking, cooling, killing, cutting and kneading, initial baking, wrapping and kneading, re-baking, drying and packaging. The finished tea products are generally placed in paper tea packaging boxes. After the tea is packaged, a detection device is needed to detect whether the amount of tea in the tea packaging box has reached the specified amount, so as to detect unqualified products such as empty packages or insufficient materials due to insufficient feed.
[0003] The empty bag detection mechanism with publication number CN210284856U has a gap between the No. 1 roller device and the No. 2 roller device in order to accurately detect the empty bag, the No. 2 roller device is movably connected to the fixed plate, the No. 2 roller device is linked to the baffle, and the baffle has a No. 1 position that blocks the sensor and a No. 2 position that does not block the sensor. During detection, one end of the packaging bag enters the gap between the No. 1 roller device and the No. 2 roller device, the No. 2 roller device does not move, the baffle blocks the sensor and the control center starts timing; when there is material in the packaging bag, the No. 2 roller device moves away from the No. 1 roller device and the baffle does not block the sensor, and the timing of the control center stops; when the packaging bag is an empty bag, the No. 2 roller device does not move, the baffle blocks the sensor, and the control center is always in a timing state; by setting the time, when the timing is greater than the set time, it is determined to be an empty bag, and then the machine is shut down or the empty bag is removed.
[0004] Although the device can accurately detect empty bags, the material of tea packaging boxes is generally hard, so the device cannot detect whether there is more or less tea in the box. The device is not suitable for detecting tea packaging boxes, and the height of the device cannot be adjusted, so it cannot adapt to the discharge conveyor belts in tea production lines with different heights. In view of this, we propose an empty bag detection mechanism for tea packaging transmission. Utility Model Content

The rotating motor 21 is fixedly connected to the rear surface of the mounting seat 1 by bolts to drive the threaded rod 22 to rotate.
[0037] Specifically, the output shaft of the rotary motor 21 is coaxially connected with a threaded rod 22 , the front end of the threaded rod 22 passes through the rear end of the mounting seat 1 and extends into the mounting groove 11 , so as to drive the mounting plate 23 to move.
[0038] Specifically, the threaded rod 22 is threadedly connected to a mounting plate 23 for driving the first push plate 24 to move, and the mounting plate 23 is slidably connected to the inner wall of the mounting groove 11 .
[0039] Specifically, the top of the mounting plate 23 is fixedly connected with the first push plate 24 by bolts, and the bottom of the first push plate 24 is in contact with the top of the weight detector body 15 to drive the first soft plate 25 to move.
