Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "first" and "second" in the present invention do not denote any particular quantity or order, but are used merely for distinguishing names.

Referring to fig. 1, the paper roll trimming device comprises a bearing platform 1 for bearing the paper roll, and the bearing platform 1 is fixed on a frame. Cutter mechanisms are arranged on two sides of the bearing table 1. It should be noted that the cutter mechanisms on both sides of the carrier have the same structure, and the projections of the cutter mechanisms on both sides in fig. 1 are just overlapped front and back, so fig. 1 can only show the cutter mechanism on one side. The cutter mechanism of the embodiment adopts a disc-shaped cutter 2 which rotates at a high speed, and the cutter 2 is arranged on a swing arm 3 which can swing up and down.

A clamping and pressing mechanism for fixing the paper roll on the bearing platform 1 is arranged above the bearing platform 1. The clamping and pressing mechanism comprises a flexible belt 4 positioned above the bearing table 1, and two cylinders 5 are connected with the flexible belt 4 and used as a first driving piece for driving the flexible belt 4 to move up and down. When the two cylinders 5 drive the flexible belt 4 to move downwards, as shown in fig. 2, the flexible belt 4 is pressed to straddle the circumferential surface of the paper roll 6, so that the paper roll 6 is fixed on the bearing table 1. After the paper roll 6 is fixed, the swing arm 3 of the cutter mechanism drives the disc-shaped cutter 2 which rotates at a high speed to move downwards, and the two ends of the paper roll 6 are cut simultaneously. The flexible tape 4 may be a rubber tape.

The cutter mechanism is not limited to the use of a disc-shaped cutter, and for example, a band saw may be used to cut both ends of the roll of paper 6 simultaneously with a band saw that reciprocates or circulates.

As a best mode, the cylinder bodies of the two air cylinders 5 are rotatably connected with the frame of the scroll edge cutting device, and the piston rods of the two air cylinders 5 are respectively connected to two ends of the flexible belt 4. As shown in fig. 2, when the flexible belt 4 is bent, the included angle between the central axes of the two cylinders 5 is changed. In this way, the flexible belt 4 straddling the circumferential surface of the paper roll can better fit the paper roll 6, so that the paper roll 6 is more firmly fixed on the bearing platform 1.

The clamping and pressing mechanism can adopt other structural forms besides the embodiment shown in fig. 1. For example, as shown in fig. 3, the clamping and pressing mechanism is a pneumatic clamp, the air cylinder 7 controls the lifting of the clamp 8, and the other air cylinder 9 controls the opening and closing of the clamp 8. When the pincers 8 are closed, the pincers 8 fix the paper roll 6 on the load-bearing table 1.

Only one of the nip mechanisms may be provided, or two or more nip mechanisms may be provided along the longitudinal direction of the roll 6. If there is only one nip mechanism, the nip mechanism should be pressed right in the middle in the length direction of the roll 6 of paper.

The carrying platform 1 of the embodiment shown in fig. 1 has an inclined slope, and the paper roll 6 placed on the carrying platform 1 can roll along the slope under the action of gravity to a position where the nip mechanism can press the paper roll. So can make the structure of whole side cut device simpler.

As an alternative embodiment, the carrier table 1 can also be an endless conveyor belt. As shown in fig. 4, a conveyor belt 10 that circulates is used as a carriage for supporting the paper roll 6, and the paper roll 6 is moved by the conveyor belt 10 to a position where the nip mechanism can press the paper roll 6. The other unreferenced structures in fig. 4 are the same as those in fig. 1.

The embodiment shown in fig. 1 is further provided with a blocking member 11 for blocking the paper roll from rolling along the bearing table 1, the blocking member 11 is connected with the cylinder 12, and the cylinder 12 is used as a second driving member for driving the blocking member 11 to move up and down. As shown in fig. 2, when the paper roll 6 rolls from top to bottom along the loading platform 1, the cylinder 12 drives the blocking member 11 to move upward to block the front of the moving direction of the paper roll 6, so that the paper roll 6 stops just at a position where the nip mechanism can press the paper roll 6.

As a preferred embodiment, the present invention may be provided without a stopper. When the paper roll just reaches the position where the clamping mechanism can press the paper roll, the clamping mechanism acts immediately to press and fix the paper roll on the bearing platform 1. The position of the roll can be detected using conventional position sensors such as electric eyes. If no stopper is provided, the stopper 11 and the cylinder 12 in fig. 1 may be deleted.

It should be noted that the first driving member for driving the flexible belt 4 to move and the second driving member for driving the blocking member 11 to move are not limited to the air cylinder, and for example, a hydraulic cylinder, an electromagnet, a motor, etc. may be used as the driving members.

The shape of the blocking member 11 may be a flat plate, a curved plate, or a curved claw. Only one blocking member 11 may be provided, or two or more blocking members may be provided along the longitudinal direction of the paper roll 6. Fig. 5-7 illustrate several different embodiments of barriers. The blocking member 11 in fig. 5 is a curved claw, and the blocking member 11 in fig. 6 and 7 is a flat plate. Fig. 5 to 7 have in common that the blocking members 11 are swung about a fixed shaft 13, and the arrows in the figures show the swinging direction of the blocking members 11. An air cylinder, a hydraulic cylinder, an electromagnet, a motor, or the like may be employed as the second driving member for driving the blocking member 11 to rotate. The second driving member may be directly connected to the blocking member 11, or may be connected to the blocking member 11 through a transmission member such as a link or a gear.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. For those skilled in the art, without departing from the spirit of the present invention, several modifications and improvements can be made without departing from the scope of the present invention. The protection scope of the present invention should be subject to the appended claims.
