[0028] Please refer to Figures 1-6 The embodiment of the utility model discloses a conveying and jacking device 100.

[0029] In an embodiment, as shown in Figure 1 And Figure 2 The conveying and jacking device 100 comprises a conveying mechanism 1 and a jacking mechanism 2 arranged on the conveying mechanism 1 and located at the output end of the conveying mechanism 1. The conveying mechanism 1 conveys products to the jacking mechanism 2, and the jacking mechanism 2 jacks up the products so that the products enter the next process.

[0030] The conveying mechanism 1 comprises a first conveying assembly 10, a second conveying assembly 12 and an adjusting structure 13, the first conveying assembly 10 and the second conveying assembly 12 are oppositely arranged and jointly form a conveying line, and the two ends of the adjusting structure 13 pass through the first conveying assembly 10 and the second conveying assembly 12 respectively. The adjusting structure 13 drives the first conveying assembly 10 and the second conveying assembly 12 to move simultaneously in the direction of approaching each other or in the direction of moving away from each other, so that the adjusting structure 13 can adjust the distance between the first conveying assembly 10 and the second conveying assembly 12, and the conveying line can convey products of different specifications. The width of the conveying line can be adjusted according to actual products at any time to adapt to different products, so that different product specifications can be conveyed without using a conveying line with an overall width suitable for the maximum specification of products, the conveying mechanism 1 is relatively light, simple in structure, low in maintenance cost and convenient to maintain.

[0031] The jacking mechanism 2 comprises a first driving member 20, a connecting structure 21, a first material jacking structure 22 and a second material jacking structure 23. Specifically, the first driving member 20 can be a pneumatic cylinder or a hydraulic cylinder. The first material jacking structure 22 is movably arranged on the first conveying assembly 10, and the second material jacking structure 23 is movably arranged on the second conveying assembly 12. The first material jacking structure 22 and the second material jacking structure 23 form a material jacking platform for carrying the products conveyed by the conveying mechanism 1. The first material jacking structure 22 and the second material jacking structure 23 are both slidably arranged on one side of the connecting structure 21. When the adjusting structure 13 adjusts the distance between the first conveying assembly 10 and the second conveying assembly 12, the first material jacking structure 22 and the second material jacking structure 23 are driven to slide on the connecting structure 21. Thus, the distance between the first material jacking structure 22 and the second material jacking structure 23 is adjusted at the same time when the distance between the first conveying assembly 10 and the second conveying assembly 12 is adjusted. Therefore, the conveying mechanism 1 and the jacking mechanism 2 can simultaneously adapt to the conveying and jacking of the same products, thereby improving the work efficiency. It is not necessary to adjust the conveying mechanism 1 and then re-adjust the jacking mechanism 2. The other side of the connecting structure 21 is arranged on the output end of the first driving member 20. When the first driving member 20 drives the connecting structure 21 to rise, the connecting structure 21 simultaneously drives the first material jacking structure 22 and the second material jacking structure 23 to rise. Thus, the first material jacking structure 22 and the second material jacking structure 23 can be simultaneously driven by one driving member. It is not necessary to arrange one driving member for each material jacking structure. Therefore, the jacking mechanism 2 has the advantages of simple structure, small size, small occupied space, low cost and high efficiency.

[0032] In an embodiment, the first material jacking structure 22 and the second material jacking structure 23 are of the same structure. The first material jacking structure 22 comprises a material jacking assembly 220 and a sliding support assembly 223. The material jacking assembly 220 is used for carrying the products conveyed by the conveying mechanism 1.

When subjected to an external force, the rolling member 222 can rotate on the shell 221. The outer circumferential side of each rolling member 222 protrudes from the opening. The products conveyed by the conveying mechanism 1 have inertia under the conveying of the conveying mechanism 1. When the products just contact the rolling members 222, the rolling members 222 rotate under the inertia of the products. The rolling members 222 push the products forward in the process of rotation, so that the products can better enter the jacking platform and avoid falling in the process of jacking.

[0033] The sliding support assembly 223 comprises a first support guide rod 224, a second support guide rod 225 and a first sliding block 226.

The first sliding block 226 is sleeved on one end of the connecting structure 21 through the through hole thereof. One end of the second support guide rod 225 is fixed to the other end of the shell 221, and the other end of the second support guide rod 225 is arranged on the first sliding block 226 through the through hole of the fourth guide block. The first sliding block 226 is sleeved on the other end of the connecting structure 21 through the through hole thereof. The first support guide rod 224 and the second support guide rod 225 can slide on the connecting structure 21 through the first sliding block 226. When the adjusting structure 13 adjusts the distance between the first conveying assembly 10 and the second conveying assembly 12, the first conveying assembly 10 and the second conveying assembly 12 drive the third guide block and the fourth guide block to move, respectively. The third guide block and the fourth guide block drive the first support guide rod 224 and the second support guide rod 225 to move, respectively. Thus, the distance between the first lifting structure 22 and the second lifting structure 23 is adjusted at the same time when the distance between the first conveying assembly 10 and the second conveying assembly 12 is adjusted. The conveying mechanism 1 and the lifting mechanism 2 can be adjusted simultaneously for the same product, which improves the work efficiency and eliminates the need to adjust the conveying mechanism 1 and then adjust the lifting mechanism 2 again.

[0034] The connecting structure 21 comprises a connecting seat 211 provided with a groove and a fifth guide rod 212. The fifth guide rod 212 is arranged in the groove of the connecting seat 211, so that the first support guide rod 224 and the second support guide rod 225 can slide on the fifth guide rod 212 through the first sliding block 226. The bottom of the connecting seat 211 is fixedly connected to the output end of the first driving member 20.

[0035] Further, the lifting mechanism 2 further comprises a first fixed plate 24, a first guide rod 25 and a second guide rod 26. The first driving member 20 is fixed on the first fixed plate 24. The first fixed plate 24 is provided with a first guide block 240 and a second guide block 241 on both sides of the first driving member 20. One end of the first guide rod 25 is arranged on the connecting structure 21, and the other end of the first guide rod 25 passes through the first guide block 240. One end of the second guide rod 26 is arranged on the connecting structure 21, and the other end of the second guide rod 26 passes through the second guide block 241. The first guide rod 25 and the first guide block 240 are arranged in cooperation, and the second guide rod 26 and the second guide block 241 are arranged in cooperation. This not only improves the stability of the connecting structure 21 and the first fixed plate 24, but also improves the directional guiding effect of the first driving member 20 on the connecting structure 21.
