[0022] like Figures 1 to 3 As shown, the vertical lifting mechanism of the embodiment of the utility model comprises:

[0023] A fixed frame 1, on which only a pair of slide rails 11 are arranged;

[0024] A driving frame 2, wherein the driving frame 2 is slidably connected to the fixed frame 1 via a pair of slide rails 11, and a plurality of lifting guide rails 21 are arranged on the driving frame 2;

[0025] Support frame 3, a plurality of guide wheels 31 are arranged at the bottom of the support frame 3, the plurality of guide wheels 31 correspond to the plurality of lifting guide rails 21 one by one, and are slidably connected with the corresponding lifting guide rails 21, changing the original sliding friction into rolling friction, which greatly reduces the required motion load;

[0026] A plurality of guide rods 4, wherein the upper ends of the plurality of guide rods 4 are fixedly connected to the support frame 3, and the lower ends of the plurality of guide rods 4 are slidably connected to the fixed frame 1 and can slide up and down in the vertical direction;

[0027] The driving mechanism 5 has an output end connected to the driving frame 2 , and can drive the driving mechanism 5 to reciprocate along the slide rail 11 .

[0028] Further, if Figures 1 to 3 As shown, in this embodiment, the lifting rail 21 includes: a lower supporting section 211, a lifting section 212 and an upper supporting section 213.

[0029] Further, if Figure 1As shown, in this embodiment, a first limit block 22 is provided on one side of the lifting guide rail 21 close to the lower support section 211 , for limiting the position of the guide wheel 31 , and further limiting the position of the support frame 3 .

[0030] Further, if Figure 1 As shown, in this embodiment, second limit blocks 12 are provided at both ends of the slide rail 11 for limiting the position of the drive frame 2 .

[0031] Further, if Figure 1 As shown, in this embodiment, the guide rod 4 and the fixing frame 1 are slidably connected via a sliding bearing 6 .

[0034] Working principle: In the initial state, the guide wheel 31 contacts the lower support section 211 of the corresponding lifting guide rail 21. When lifting the product, the driving mechanism 5 drives the driving frame 2 to move to the left, so that the upper support section 213 of the lifting guide rail 21 is in contact with the corresponding guide wheel 31. In this process, the supporting frame 3 is lifted upward to the maximum height. Conversely, the driving mechanism 5 drives the driving frame 2 to move to the right until the supporting frame 3 is in the initial position.
