The left end and the right end of the main shaft 1 are respectively provided with a left paper clamping rocker arm 11 and a right paper clamping rocker arm 12. As shown in fig. 3, the left and right gripper arms 11, 13 are arc-shaped and have a thick stainless steel solid structure, thereby being able to bear a large weight without being deformed.

The tail ends of the left paper clamping rocker arm 11 and the right paper clamping rocker arm 12 are respectively provided with a left chuck 13 and a right chuck 14. The chucks 13 and 14 are positioned at the inner sides of the left and right paper clamping rocker arms 11 and 12, are conical, and are arranged on the left and right paper clamping rocker arms 11 and 12 through bearings. The conical pointed ends are oppositely arranged, so that the conical pointed ends can be conveniently inserted into through holes at two ends of the core cylinder of the original paper roll.

In order to clamp the paper, the left and right clamping heads 13, 14 need to be separated to release the used paper roll, and simultaneously, the left and right clamping heads 13, 14 can be close to each other to clamp the new paper roll, so that a slide rail is arranged on the main shaft 1 along the axial direction, and the left and right paper clamping swing arms 11, 12 can move along the rail on the slide rail so as to be close to or separate from each other, thereby driving the left and right clamping heads 13, 14 to clamp the paper roll or put down the paper roll. The structure of the specific sliding rail has related technical documents and published patents in the prior art, and is not described in detail herein.

The left paper clamping rocker arm 11 and/or the right paper clamping rocker arm 12 can be driven by the oil cylinder to move along the sliding rail. For example, as shown in fig. 1, a rocker arm driving cylinder 15 is installed on the main shaft 1, a piston end, i.e., a moving end, of the rocker arm driving cylinder 15 is connected to the left paper clamping rocker arm 11 or the right paper clamping rocker arm 12, and the other end is fixed to the opposite side of the main shaft 1, so that the piston moves to drive the left paper clamping rocker arm 11 or the right paper clamping rocker arm 12 to approach or move away from each other.

The rocker arm not only needs to move horizontally along the main shaft 1, but also needs to swing around the axis of the main shaft 1, so as to clamp the original paper roll from the ground or a conveyor belt, then the original paper roll is lifted to enter a production line, and the original paper roll is put down when the original paper is used up. Therefore, as shown in fig. 1, the main shaft 1 is further provided with a left driving cylinder 17 and a right driving cylinder 18, which are cylinders of the same type and are parallel to each other, i.e. the two cylinders are completely overlapped from a side view such as shown in fig. 3. Further, the left driving cylinder 17 and the right driving cylinder 18 are supplied with oil from the same oil path and are driven synchronously. Due to the arrangement, the stress on the two sides of the main shaft 1 is completely balanced, and the influence on the service life of the main shaft 1 caused by the stress due to uneven stress can be avoided. Preferably, on the basis, the left paper clamping rocker arm 11 and the right paper clamping rocker arm 12 are always symmetrically distributed on two sides of the spindle 1 relative to the spindle 1 no matter how the left paper clamping rocker arm and the right paper clamping rocker arm move, so that the stress balance can be further optimized, the stability of the paper clamping process is ensured, and the shaking and the inclination are reduced.

The left and right auxiliary paper clamping rocker arms have the same structure, are symmetrical along the middle section of the auxiliary shaft 2, have the same structure as the left and right paper clamping rocker arms, are symmetrically arranged relative to the vertical bisecting plane of the main shaft 1 and the auxiliary shaft 2, and are not described again.

Similarly, as shown in fig. 2, a pair of left auxiliary flange plates 271 is disposed on the auxiliary shaft 2 outside the left auxiliary paper clamping swing arm 21 and inside the frame 3, a left auxiliary pivot 273 is disposed between the two left auxiliary flange plates 271, one end of the left auxiliary driving cylinder 27 is mounted at the bottom of the frame 3, and the other end is rotatably connected to the left auxiliary pivot 273. A pair of right auxiliary flange pieces are arranged on the auxiliary shaft outside the right auxiliary paper clamping rocker arm and inside the rack, a right auxiliary pivot is arranged between the two right auxiliary flange pieces, one end of a right auxiliary driving oil cylinder is arranged at the bottom of the rack, and the other end of the right auxiliary driving oil cylinder is rotatably connected to the right auxiliary pivot.

As shown in fig. 3, the left sub-actuating cylinder 27 and the right sub-actuating cylinder are disposed obliquely, and their piston ends are respectively connected to the left sub-pivot 273 and the right sub-pivot, and their fixed ends respectively extend to the oblique rear of the main shaft 1. From the side view shown in fig. 3, the left sub drive cylinder 27 and the right sub drive cylinder are completely overlapped, and thus the right sub drive cylinder is not shown in the drawing. Similarly, the left and right auxiliary driving oil cylinders and the bottom surface of the frame form an acute angle of less than 45 degrees. It is preferable that the left and right drive cylinders 17 and 18 and the left and right sub drive cylinders are of the same type, and the angle formed by the four cylinders with the bottom surface is the same when the rocker arm is at the same swing angle, and the four cylinders are in a cross form as shown in fig. 3 (not actually crossed, but crossed in a side view angle).

Because the main shaft 1, the auxiliary shaft 2 and the structures and devices on the main shaft and the auxiliary shaft all adopt the same form, the balance of transmission can be achieved to the maximum extent, and the unstable condition of transmission is reduced and avoided; and the paper clamping device of the scheme has smaller volume and simpler structure.

While the present invention has been particularly shown and described with reference to preferred embodiments thereof, and many methods and approaches to the same have been shown and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
