[0031] Embodiment one

[0032] Figure 1 An explosion structure schematic diagram of the suspension cutter in the embodiment one of the utility model is shown. Figure 2 A three-dimensional structure schematic diagram of the shaft sleeve of the suspension cutter in the embodiment two of the utility model is shown. Figure 1 And Figure 2 A suspension cutter, the suspension cutter comprises a shaft sleeve 2, a rotating shaft 1 and a blade 3. The shaft sleeve 2 is sleeved on the rotating shaft 1. The blade 3 is provided with at least two pieces, and the blade 3 is arranged on the rotating shaft 1 and the shaft sleeve 2 respectively. Two groups of blades 3 work simultaneously, increase the contact area of the blade 3 and the food material, so that the food material is cut more frequently, and the chopping efficiency of the food material is improved. Wherein, one of the rotating shaft 1 and the shaft sleeve 2 is provided with an annular wave-shaped track 11, and the other is provided with a limiting protrusion 21. Along the axial direction of the rotating shaft 1, the rotating shaft 1 is further provided with a limiting key 15, and the upper end of the shaft sleeve 2 is provided with a limiting groove 221. When the rotating shaft 1 rotates, the limiting protrusion 21 slides along the undulating track surface 113 of the wave-shaped track 11, which promotes the rotation of the shaft sleeve 2 around the rotating shaft 1. At the same time, the shaft sleeve 2 moves up and down along the axial direction of the rotating shaft 1. After the limiting protrusion 21 and the wave-shaped track 11 push the shaft sleeve 2 to move to the highest point of the wave-shaped track 11, the limiting key 15 is clamped into the limiting groove 221. By repeatedly driving the main shaft to rotate and stopping driving the main shaft, the up-and-down reciprocating movement of the shaft sleeve 2 is realized. The up-and-down reciprocating movement of the shaft sleeve 2 drives the blade 3 on the shaft sleeve 2 to also move up and down, so that the blade 3 can chop in a larger range. The up-and-down movement of the cutter can also better stir the food material, thereby improving the chopping efficiency of the suspension cutter.

[0033] The wave-shaped track 11 comprises two wave crests 111 and two wave troughs 112, and the wave crests 111 and the wave troughs 112 are arranged alternately. Figure 1 And Figure 2 When the limiting protrusion 21 slides along the wave-shaped track 11 for one circle, the shaft sleeve 2 will reciprocate twice along the axial direction of the rotating shaft 1. The number of reciprocating movements of the shaft sleeve 2 is limited to twice, so as to avoid that the frequency of the reciprocating movement of the shaft sleeve 2 is too high, which affects the stability of the suspension cutter in operation.

[0034] Preferably, the wave-shaped track 11 is arranged on the rotating shaft 1. That is, the rotating shaft 1 supports the shaft sleeve 2 through the track surface 113; the track surface 113 has a large supporting surface, which can provide better stability.

[0035] More preferably, the limiting protrusion 21 is arranged on the shaft sleeve 2. The limiting protrusion 21 is arranged in a ring shape, and the lower surface of the limiting protrusion 21 forms a wave-shaped surface 211 corresponding to the track surface 113 of the wave-shaped track 11. When the rotating shaft 1 rotates, the wave-shaped surface 211 slides on the track surface 113. The ring-shaped arrangement of the limiting protrusion 21 forms the wave-shaped surface 211, which increases the area of the entire lower surface of the limiting protrusion 21, and further increases the contact area of the limiting protrusion 21 and the wave-shaped track 11, that is, the rotating shaft 1 supports the rotating shaft 1 more stably through a larger contact area. The stability of the structure of the suspension cutter is improved.

[0036] Please refer to Figure 1 , the rotating shaft 1 includes a first section 12 and a second section 14, the diameter of the first section 12 is smaller than the diameter of the second section 14. A step 13 is formed between the first section 12 and the second section 14. The limiting key 15 is arranged on the first section 12. Correspondingly, the shaft sleeve 2 is provided with an extension 22 on the inner side. The limiting slots 221 are formed between adjacent extensions 22. That is, the shaft sleeve 2 can be directly sleeved on the rotating shaft 1 from top to bottom, the limiting key 15 is arranged on the first section 12 with small diameter, and does not interfere with the assembly between the shaft sleeve 2 and the rotating shaft 1. At the same time, the arrangement of the extension 22 ensures that the limiting key 15 can normally be clamped into the limiting slot 221. While ensuring the normal work of the suspended cutter, the assembly between the rotating shaft 1 and the shaft sleeve 2 is simplified.

[0037] Preferably, when the shaft sleeve 2 moves to the lowest position along the rotating shaft 1, the extension 22 contacts the step 13. The position of the shaft sleeve 2 on the rotating shaft 1 is quickly positioned by the step 13. At the same time, when the shaft sleeve 2 moves to the lowest position along the rotating shaft 1, the extension 22 contacts and supports the step 13, further improving the stability of the structure of the suspended cutter.

[0038] Please refer to Figure 1 , the limiting key 15 is arranged at least three, and the limiting key 15 is uniformly arranged around the axial direction of the rotating shaft 1. The limiting slots 221 are arranged corresponding to the position and number of the limiting key 15. Arranging multiple limiting keys 15 and limiting slots 221 can increase the contact area between the rotating shaft 1 and the shaft sleeve 2, disperse the load of torque transmission, and thus increase the torque carrying capacity of the entire suspended cutter.

[0039] Preferably, the end of the upper part of the rotating shaft 1 is provided with a spline 16. It is convenient to connect the rotating shaft 1 with a motor or other torque output device.

[0040] The specific working process of the embodiment is as follows:

[0041] In the static state, the limiting protrusion 21 is located in the wave trough 112 of the wave track 11 under the influence of gravity. When the suspended cutter works, the rotating shaft 1 is directly driven to rotate, and the rotating shaft 1 drives the shaft sleeve 2 to rotate in the same direction through friction. Affected by resistance, the rotating speed of the shaft sleeve 2 will be lower than that of the rotating shaft 1, that is, the limiting protrusion 21 will slide along the wave track 11, that is, the shaft sleeve 2 will move up and down along the axial direction of the rotating shaft 1. After the shaft sleeve 2 moves to the track surface 113 at the wave peak 111, the limiting key 15 is clamped into the limiting slot 221. At this time, the limiting key 15 and the limiting slot 221 cooperate to transmit torque. The rotating shaft 1 and the shaft sleeve 2 rotate synchronously. Stop driving the rotating shaft 1 to rotate, and under the action of gravity, the shaft sleeve 2 moves downward along the track surface 113. Until the limiting protrusion 21 slides to the track surface 113 at the wave trough 112. Redrive the rotating shaft 1 to rotate. Repeat the above actions of driving the rotating shaft 1 to rotate, temporarily stopping driving the rotating shaft 1 to rotate, to realize the up-and-down reciprocating movement of the shaft sleeve 2 on the rotating shaft 1.

[0042] Embodiment two

[0043] Figure 3 An explosion structure schematic diagram of the suspended cutter in embodiment two of the utility model is shown. Figure 3 Based on embodiment one, embodiment two discloses a suspended cutter, the limiting key 15 on the rotating shaft 1 is detachably arranged on the rotating shaft 1. The limiting key 15 and the rotating shaft 1 can be clamped, inserted and screwed. At this time, the rotating shaft 1 is an axial body with consistent upper and lower diameters, and the limiting groove 221 is directly arranged on the main body of the shaft sleeve 2. During assembly, the limiting key 15 is first removed, then the shaft sleeve 2 is sleeved on the rotating shaft 1, and finally the limiting key 15 is reinstalled. At this time, only a small gap allowing relative movement is left between the shaft sleeve 2 and the rotating shaft 1. The overall stability and structural strength of the suspended cutter are enhanced.
