Description
Technical Field
The utility model relates to the technical field of food processing, in particular to a multiaxial adjusting mechanism of a clamping jaw of a seed cutting machine.
Background
The existing food, such as the slicing of betel nuts, is mainly to clamp the betel nuts under a cutter through a clamp, or the betel nuts freely fall into betel nut molds with fixed shapes, because of the diversity of betel nut shapes, the betel nuts clamped or falling into the molds have great randomness in a certain range of positions and directions, and the positions of the cutters are generally fixed, so that the cutting seams of the cut betel nuts deviate from ideal cutting seams, and the quality of the betel nut slicing is affected.
And because the clamp can not adjust the size and the direction, the positions of betel nuts with different sizes entering the clamp have certain randomness, so the cutting edge position and the cutting direction of the slice also have certain randomness and are possibly not ideal positions and directions, and thus, some betel nuts are reduced in grade, and even some betel nuts are cut and wasted, so that the yield is reduced.
Although the conventional mechanical device is improved in terms of multi-directional adjustment, for example, chinese patent CN 215589336U discloses a clamping translation rotating device for intelligent slicing of food, which comprises a sliding table, a first rotating mechanism arranged on the sliding table, and a second rotating mechanism arranged on the first rotating mechanism, wherein the first rotating mechanism and the second rotating mechanism move back and forth along the sliding table at the same time, the first rotating mechanism realizes a first rotating motion along the left and right direction of the axis of the back and forth motion of the sliding table, and the second rotating mechanism realizes a second rotating motion along the first rotating mechanism.
For the adjusting mechanism, the Y-axis direction is adjusted in a rotating mode, so that the adjusting precision is poor, and the betel nuts are not well centered during clamping.
In addition, the clamping jaw is higher in connection position of the clamping device due to the relation of multi-axis movement and is connected with the base through the first rotating mechanism, so that the height difference between the clamping jaw and the base is larger, the accumulated error existing in the whole mechanism assembly is reflected in the position of the clamping jaw of the mechanism, the activity of the whole clamping jaw is large, and the position is inaccurate.
Therefore, we propose a multi-axial adjusting mechanism for a clamping jaw of a seed cutting machine.
