TECHNICAL FIELD
[0001] The utility model relates to a cylinder paper conveying device. BACKGROUND
[0002] Printing is a technology that makes the content of original draft be copied in batches by transferring ink to the surface of paper, fabric, plastic product, leather and other materials through the processes of plate making, ink applying and pressure applying. Cylinder paper is one of the necessary raw materials in the printing process, and it needs to be transported to the printing equipment before printing. The existing transport tool is mainly a clamping forklift, which mainly uses two arms to clamp and position the cylinder paper. The existing arm is mostly of an integral structure, and can only transport cylinder paper within a certain diameter range, which has poor versatility. SUMMARY
[0003] In view of the deficiencies in the above problems, the utility model provides a cylinder paper conveying device.
[0004] To achieve the above purpose, the utility model provides a cylinder paper conveying device, which comprises a vehicle body, a door-shaped frame arranged on the right side of the vehicle body, a clamping mechanism installed on the right side of the door-shaped frame through a lifting seat, the clamping mechanism comprises a positioning support, two arms are symmetrically arranged on the positioning support along the front and back directions, the two arms are curved towards each other to form an arc structure, the arm comprises a first cantilever and a second cantilever, one end of the first cantilever is hinged to the positioning support through a second pin shaft, the other end of the first cantilever is detachably connected to the second cantilever through a dovetail structure, and elastic blocks are arranged on the inner walls of the first cantilever and the second cantilever.
[0005] As a further improvement of the utility model, matching dovetail grooves and dovetail sliding blocks are arranged at the joints of the first cantilever and the second cantilever, and the dovetail grooves are open at the upper end and closed at the lower end.
[0006] As a further improvement of the utility model, a hydraulic cylinder is arranged between the first cantilever and the positioning support, one end of the cylinder body of the hydraulic cylinder is hinged through a first pin shaft, and the end of the cylinder rod of the hydraulic cylinder is hinged to the middle part of the outer wall of the first cantilever.
[0007] The utility model has the advantages that:
[0008] The arm structure in the device is composed of a detachable first cantilever and a second cantilever, and elastic blocks are additionally arranged on the inner side surfaces of the first cantilever and the second cantilever. When clamping the cylinder paper, the elastic blocks are tightly attached to the outer wall surface of the cylinder paper, the contact area between the elastic blocks and the cylinder paper is large, the clamping effect is good, and the device is suitable for clamping cylinder papers with different diameters and has good versatility.
