Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a packaging box clamping structure and a conveying device using the structure. Background Art

[0002] Packaging box clamping conveyor belts are widely used on packaging production lines. The clamping mechanism on these conveyor belts is used to hold the boxes in place and secure them for transport along the production line. Existing systems secure the clamping mechanism to the chain by pressing it against the arc of a chain link. This point-contact connection between the clamping mechanism and the chain makes it prone to side-to-side movement during conveying, affecting the clamping effect. Furthermore, the existing clamping mechanism's spacing adjustment range is limited, making it difficult to accommodate smaller packaging boxes. Utility Model Content

[0008] Furthermore: an avoidance slope is provided on the mounting portion, and the avoidance slope and the stepped groove are located on opposite surfaces of the mounting portion.

[0009] A conveying device includes the packaging box clamping structure described above, and also includes a first conveying chain, a second conveying chain, a third conveying chain, and a fourth conveying chain, wherein the first conveying chain, the second conveying chain, the third conveying chain and the fourth conveying chain are respectively provided with a supporting block and a fixed block, the supporting block and the supporting position are adapted to each other, the first clamping box finger and the second clamping box finger are located between the first conveying chain and the second conveying chain, and the first clamping box finger is fixed to the first conveying chain through the fixed block, the second clamping box finger is fixed to the second conveying chain through the fixed block, the third clamping box finger and the fourth clamping box finger are located between the third conveying chain and the fourth conveying chain, and the third clamping box finger is fixed to the third conveying chain through the fixed block, and the fourth clamping box finger is fixed to the fixed block and the fourth conveying chain.
