[0049] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0050] Please refer to Figure 1 , the technical solution adopted by the utility model is:

[0051] A scallion cutting machine comprises a shell and a driving mechanism, wherein the inner cavity of the shell is rotatably connected to a tool assembly with two blades arranged in an interlaced manner, the blade spacing between the two tool assemblies is adjustable, and the tool assembly is provided with a material guide structure for guiding sliced ​​food out of the shell, and a transmission matching structure is provided between the output end of the driving mechanism and the driving shaft of one of the tool assemblies, which allows the output end of the driving mechanism to have a movable space, so that the driving shaft of the tool assembly and the output end of the driving mechanism can be quickly assembled.

[0052] From the above description, it can be seen that the beneficial effects of the utility model are:

[0053] The present solution is to connect two tool assemblies with staggered blades rotatably in the inner cavity of the shell, and the distance between the blades of the two tool assemblies is adjustable, so that food of different thicknesses can be cut; and the tool assembly is provided with a material guide structure for guiding the sliced ​​food out of the shell, which can guide the sliced ​​material out and prevent the sliced ​​material from being stuck between the blades and affecting the rotation of the tool assembly; a transmission matching structure is provided between the output end of the drive mechanism and the drive shaft of one of the tool assemblies, which allows the output end of the drive mechanism to have a movable space, so that the drive shaft of the tool assembly and the output end of the drive mechanism can be quickly assembled without precise alignment, thereby greatly reducing the difficulty of assembly.

[0054] Furthermore, the transmission matching structure includes a connecting mechanism and an output shaft connected to the output end of the driving mechanism, the connecting mechanism is used to connect the driving shaft of the tool assembly with the output shaft, a polygonal mounting hole is provided on the connecting mechanism, the cross-sectional shape of the output shaft is a polygon, the free end of the output shaft is inserted into the mounting hole, a spacing is provided between the output shaft and the mounting hole, and the output shaft abuts against the inner wall of the mounting hole after rotating a certain angle.

[0055] From the above description, it can be seen that by providing a transmission matching structure with a gap, the output shaft of the driving mechanism can have movable space, which is convenient for rapid assembly of the tool assembly without the need for precise alignment, thereby greatly reducing the difficulty of assembly.

[0056] Furthermore, the connecting mechanism includes a mounting connecting head, the mounting hole is arranged on the mounting connecting head, a connecting piece is embedded in the mounting hole, the connecting piece has a polygonal through hole, the free end of the output shaft is inserted into the through hole, a spacing is arranged between the output shaft and the inner wall of the through hole, and the output shaft abuts against the inner wall of the through hole after rotating a certain angle.

[0057] Furthermore, the connection mechanism further comprises a first output gear, and the drive connector is arranged on an end surface of the first output gear;

[0059] From the above description, it can be seen that during assembly, the output shaft rotates a certain angle and then abuts against the inner wall of the mounting hole, so that the output shaft and the connecting mechanism form a whole. In this way, the driving mechanism starts to drive the output shaft to rotate, and the rotation of the output shaft drives the first output gear to rotate. The rotation of the first output gear drives the second output gear to rotate, thereby driving the two tool assemblies to rotate.

[0060] Furthermore, the two tool assemblies are respectively a first tool assembly and a second tool assembly, one end of the driving shaft of the first tool assembly extends out of the shell and is rotatably connected to a knob member, the knob member is threadedly connected to the shell, and when the knob member and the shell rotate relative to each other, the first tool assembly is driven to move axially to adjust the spacing between the blades on the first tool assembly and the second tool assembly.

[0061] From the above description, it can be seen that the axial position of the tool is adjusted by the threaded structure, and then the relative position relationship between the first tool assembly and the second tool assembly is adjusted. When in use, the distance between the blades on the first tool assembly and the second tool assembly can be adjusted by simply rotating the knob, so that food of different coarsenesses can be cut.

[0062] Furthermore, the outer wall of the shell is connected with a sleeve, the inner cavity of the sleeve is provided with an internal thread, and the outer wall of the knob is provided with an external thread that cooperates with the internal thread.

[0064] Furthermore, the tool assembly includes a plurality of main blades mounted on the same drive shaft, and the material guide structure includes a plurality of partitions, a partition is arranged between two adjacent main blades, the partition is mounted on the outside of the drive shaft and is rotatably connected to the drive shaft, and the partition is used to guide the sliced ​​material out.

[0065] From the above description, it can be seen that by setting the above structure, the sliced ​​material can be smoothly discharged under the action of the partition, avoiding some sliced ​​material from being stuck between the blades, affecting the rotation of the tool assembly and thus affecting the overall machine operation.

[0066] Furthermore, the partition includes an annular portion, a material guiding portion and a connecting portion, the annular portion is respectively connected to the material guiding portion and the connecting portion, the annular portion is sleeved on the outside of the driving shaft and is rotatably connected to the driving shaft, all the connecting portions extend out of the main blade, the portion of the connecting portion extending out of the main blade is installed inside the shell through a fixed shaft, and the material guiding portion is used to export the sliced ​​material.

[0067] Furthermore, a gasket is provided between two adjacent main blades, the gasket is sleeved outside the driving shaft and is rotatably connected to the driving shaft, the partition is sleeved outside the gasket and a spacing is provided between the partition and the gasket, and the thickness of the gasket is greater than the thickness of the partition.

[0068] From the above description, it can be seen that by arranging a gasket between two adjacent main blades, the thickness of the gasket can be changed to adjust the distance between the main blades to achieve the adjustment of the thickness of the food.
