With the development of various industries, the speed of die-cutting is required to be faster and faster, and the cost of die-cutting is required to be controlled. At the same time, the size of die-cut products is also required to be larger and larger, and the longest product size exceeds 2 meters.

[0003] The rotary cutter roller currently used in rotary die cutting is a shaft-shaped product. When it is actually clamped and positioned, the clamps currently on the market cannot position it well. Therefore, we propose a special clamp for rotary cutter roller processing to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the rotary cutting roller used in the current rotary die cutting is a shaft-shaped product. When the rotary cutting roller is actually clamped and positioned, the clamp currently on the market cannot well position it. A special clamp for rotary cutting roller processing is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A special fixture for processing a rotary cutting roller comprises a bottom plate, an L-shaped support plate is rotatably connected to one side of the top of the bottom plate, a limiting frame is fixedly installed on the top of the L-shaped support plate, an L-shaped movable plate is slidably connected through the limiting frame, and a support pipe is rotatably connected to one side of the L-shaped support plate and the L-shaped movable plate that are close to each other. The fixture also comprises:

[0007] Two clamping mechanisms, the two clamping mechanisms are respectively mounted on two supporting tubes, and the two clamping mechanisms clamp the same rotary cutting roller;

[0008] The flipping mechanism is installed on the top of the bottom plate, the top of the flipping mechanism is connected to the bottom of the L-shaped support plate, and the flipping mechanism is used to drive the L-shaped support plate to rotate 90 degrees.

[0009] In a possible design, the clamping mechanism includes a mounting plate fixedly sleeved on the support tube, an elastic component is installed through the mounting plate, and one side of the elastic component is clamped with the rotary cutting roller.

[0010] In a possible design, the elastic component includes two limiting shafts that symmetrically pass through the mounting plate and are slidably connected to the mounting plate. One end of the two limiting shafts is fixedly installed with a same pressure ring, which is used to clamp the rotary cutting roller. The other end of the two limiting shafts is fixedly installed with a same limiting ring, which is slidably sleeved on the support tube. A compression spring is sleeved on the limiting shaft, and both ends of the compression spring are respectively fixedly connected to one side of the pressure ring and one side of the mounting plate.

[0011] In one possible design, a screw is fixedly installed at the bottom of the L-shaped support plate, and a threaded tube is rotatably connected to the bottom of the L-shaped movable plate. One end of the screw extends into the threaded tube, and the screw is threadedly connected to the threaded tube. A handwheel is fixedly installed at one end of the threaded tube.

[0012] In one possible design, the flipping mechanism includes two telescopic components symmetrically installed on the top of the base plate, both telescopic components are connected to the bottom of the L-shaped support plate, a slide rail is fixedly installed on the top of the base plate, a slide plate is slidably connected to the slide rail, a transmission plate is fixedly installed on the top of the slide plate, push shafts are fixedly installed on the top of both sides of the transmission plate, the push shafts are connected to the corresponding telescopic components, an electric push rod is fixedly installed on the top of the base plate, and the output shaft of the electric push rod is fixedly connected to one side of the transmission plate.

At this time, under the transmission effect of the thread with the screw rod, the L-shaped movable plate can be driven to approach the L-shaped supporting plate, so that the distance between the two pressure rings can be reduced. After the two pressure rings clamp the rotary cutter roller, the elastic force of the four compression springs in the stressed state can be used to clamp the rotary cutter roller, and the two ends of the rotary cutter roller can be respectively inserted into the corresponding supporting tubes, so that the rotary cutter roller can be stably positioned. Since the supporting tube can rotate, after the rotary cutter roller is clamped, the rotary cutter roller can rotate along its axial direction.
