Description

Technical Field

[0001] The present invention belongs to the field of food processing, and particularly relates to a Chinese cabbage root-removing device and a root-removing method. Background Art

[0002] Chinese cabbage is a vegetable deeply loved by people, and the demand for Chinese cabbage is huge. Many favorite foods can be made from Chinese cabbage. With the progress of technology, many foods have achieved automated mechanical processing, and there are countless foods containing Chinese cabbage. However, in the processing of Chinese cabbage, since the root of Chinese cabbage is harder than other parts of Chinese cabbage and is not suitable for simultaneous processing with the rest of the Chinese cabbage, generally, root-removing operation is required to meet the requirements of normal food mechanical processing.

[0003] The current mainstream Chinese cabbage root-removing device uses a blade to cut off the root. For example, the Chinese patent with the authorization announcement number CN219438163U provides a Chinese cabbage root-removing mechanism, which fixes the Chinese cabbage and then transports it to the cutting knife position in turn by a conveyor belt for root-cutting operation. Although this achieves the purpose of removing the root of Chinese cabbage, the cutting area is large, resulting in a great waste, which does not meet the needs of processing manufacturers and causes a large amount of waste. Moreover, the root-removing devices on the market all adopt a destructive root-removing method, which directly crushes the root of Chinese cabbage and cannot be reused. Summary of the Invention

[0036] Discharging auxiliary mechanism, installed directly below the cabbage placing position under the cabbage root removing mechanism, including a sixth cylinder 81, a plurality of tile-shaped top plates 82, and a substrate 83. The plurality of tile-shaped top plates 82 are fixedly connected to the substrate 83. The substrate 83 is fixedly connected to the output end of the sixth cylinder 81. The cabbage placing groove of the conveying device is provided with a tile-shaped top plate through hole, and the tile-shaped top plate passes through the tile-shaped top plate through hole to push and top the cabbages; the cross sections of the plurality of tile-shaped top plates fall on the same circle. The auxiliary discharging mechanism is used to lift the cabbages in the cabbage positioning groove. At this time, the push plate of the discharging mechanism is pushing, which is beneficial to the smooth discharging of the cabbages and prevents the cabbages from being damaged due to jamming.

[0037] Usage method: Place the Chinese cabbage on the Chinese cabbage placement position on the turntable mechanism, and then the turntable mechanism sends the Chinese cabbage to the position of the Chinese cabbage root removal device. During the transportation process, the distance measuring sensor will measure the distance from the Chinese cabbage root, and then obtain the height of the Chinese cabbage. When the Chinese cabbage is transported under the position of the Chinese cabbage root removal device, the Chinese cabbage root removal lifting device drives the Chinese cabbage root removal device to move downward. At the same time, the Chinese cabbage root removal device drives the claw and the pressing plate mechanism to descend synchronously, position the Chinese cabbage and make the claw insert into the root of the Chinese cabbage. During the continuous penetration process, each claw gradually gathers, cutting off the connection between the root of the Chinese cabbage and the rest of the Chinese cabbage. It can be completely cut or partially cut. The main reference basis is the height of the Chinese cabbage measured by the distance measuring sensor, and in combination with the cooperation of the root removal lifting mechanism and the root removal mechanism, try to reduce the size of the cut root. Then lift the Chinese cabbage root removal mechanism. At this time, the chute of the Chinese cabbage root collection mechanism moves and inserts under the Chinese cabbage root removal mechanism. The claw of the Chinese cabbage root removal mechanism releases the Chinese cabbage root and falls into the chute for collection. At the same time, the pressing plate mechanism rises, and the turntable mechanism transports the de-rooted Chinese cabbage to the next pause station, and is pushed out of the turntable mechanism by the push plate of the discharging mechanism and collected. The claw of the root removal mechanism in the solution of the present invention does not need to completely disconnect the connection near the root of the Chinese cabbage. Therefore, after cooperating with the distance measuring sensor, the root of the Chinese cabbage can be removed with less loss.

[0038] This embodiment involves the coordination of multiple actions. Components such as servo motors and cylinders can be set for step-by-step programming control, and no detailed description will be given here.
