Description

Technical Field

[0001] This utility model relates to the field of roll paper slitting equipment, specifically a roll paper bevel slitting equipment with adjustable cutting angle. Background Technology

[0002] A rewinder is a specialized piece of equipment used for paper, mica tape, and film. Its purpose is to rewind paper rolls produced by a paper machine sequentially, resulting in finished paper products for shipment. The use of AC drives instead of DC drives in rewinders has become a trend in the paper machinery industry. Paper rolls produced by paper winding machines are relatively soft, may contain internal damage or breaks, have uneven edges, and are often too narrow for direct use in paper processing or printing machines. Most paper types must undergo edge trimming, slitting, splicing, and rewinding on a core in a rewinder to form finished paper rolls with specific specifications and tightness requirements before they can be shipped.

[0003] The rewinding process mainly accomplishes three tasks: first, removing the rough edges of the original paper; second, cutting the entire sheet of original paper into several widths that meet the user's specifications; and third, controlling the diameter of the finished paper rolls to ensure they meet the factory specifications.

[0004] However, existing slitting processes are usually vertical cuts. When tearing, the tension is evenly distributed across the entire paper web, requiring a large force to break the fiber structure. This can easily lead to uneven tears or even tearing the entire sheet of paper. Furthermore, during high-speed winding and long-term compressed storage, the fibers at the edges of the paper may sometimes stick together slightly. If this sticking occurs at the straight edges, users may tear out several layers at once or tear through several layers before breaking the paper, resulting in waste. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a roll paper bevel cutting device with adjustable cutting angle to solve the technical problems that straight cut edges are prone to uneven tearing or even tearing the whole sheet of paper when tearing, and that the edges of the paper will stick together during storage and transportation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable cutting angle paper roll beveling device, comprising a frame, a fixed shaft seat fixedly connected to one side of the frame, an angle handle rotatably connected to the outer wall of the fixed shaft seat, a pull rod rotatably connected to one end of the angle handle, the pull rod rotatably connecting to a cutting device through the frame, the cutting device rotatably connecting to the frame via a rotating shaft, a cutting wheel rotatably connected inside the cutting device, a transmission gear fixedly connected to one end of the cutting wheel through the cutting device, a fixed plate rotatably connected to one end of the transmission gear, a first motor fixedly connected to one side of the fixed plate, and the transmission gear fixedly connected to the first motor through the fixed plate.

[0007] By adopting the above technical solution, when the power is turned on, the first motor is energized and rotates. The first motor is mounted on a fixed plate, and the output end of the first motor passes through the fixed plate and is connected to a transmission gear. The transmission gear meshes with another set of transmission gears, thereby driving the cutting wheel to rotate and cut the paper. The cutting device is rotatably connected to the frame via a rotating shaft. A pull rod is rotatably connected inside the frame, and the pull rod passes through one end of the frame and is rotatably connected to an angle handle. One end of the angle handle is rotatably connected to the frame via a fixed shaft seat. When the angle handle is turned, the pull rod moves to the other end, thereby pulling the cutting device to rotate around the rotating shaft on the frame, thus achieving the effect of adjusting the angle of the cutting device to cut the paper.

[0008] Furthermore, a second motor is fixedly connected to the bottom of the frame, and a driving bevel gear is fixedly connected to the output end of the second motor. Two sets of driven bevel gears are drivenly connected to the outer wall of the driving bevel gear. A transmission rod is fixedly connected to one end of each set of driven bevel gears. One end of the transmission rod is rotatably connected to the inside of the frame. Two sets of gear shafts are rotatably connected to the inside of the frame. A transmission belt is drivenly connected to the outer wall of each set of gear shafts. The inner wall of each set of transmission belts is drivenly connected to the transmission rod.

[0009] By adopting the above technical solution, the second motor is powered and rotates. The output end of the second motor is connected to a driving bevel gear. Two identical driven bevel gears are connected to both sides of the driving bevel gear. A transmission rod is fixed to one end of the driven bevel gear, and a gear is provided at one end of the transmission rod. One set of transmission rods is connected to the two sets of gear shafts through a transmission belt.

[0010] Furthermore, a first winding rod is rotatably connected inside the frame, and two sets of clamping pawls are movably connected to the outer wall of the first winding rod. A second winding rod is also rotatably connected inside the frame, and two sets of clamping pawls are also movably connected to the outer wall of the second winding rod. A transmission belt is driven to the outer wall of one end of the second winding rod, and a gear shaft is driven to the inner wall of the transmission belt through toothed transmission. A limit rod is rotatably connected inside the frame, and both ends of the limit rod are driven to transmission rods through transmission belts. The transmission rods are driven to gear shafts through transmission belts, and the gear shafts are driven to paper winding rods through toothed transmission. The outer wall of the paper winding rod is rotatably connected to the outer wall of the frame.

[0011] By adopting the above technical solution, when in use, the paper roll is removed from the frame, the uncut roll of paper is loaded onto the paper roll, and then the paper roll is put back onto the frame. One end of the paper roll is equipped with a gear, which meshes with the gear on the gear shaft located on the frame below the paper roll, pulling out the roll of paper and dividing it into two parts, which are respectively wound around the clamping pawls on the first winding rod and the clamping pawls on the second winding rod. One set of gear shafts is connected to the gear on the second winding rod through a transmission belt, and the other set of transmission rods is directly connected to the gear on the first winding rod through a transmission belt. Both sets are connected to the gears at both ends of the limit rod through transmission belts. When the second motor rotates, it synchronously drives the first winding rod, the second winding rod, the limit rod, and the paper roll to rotate synchronously.

[0012] Furthermore, multiple sets of extension rods are fixedly connected to the inner wall of the frame, and pressure wheels are rotatably connected inside the multiple sets of extension rods. The pressure wheels play the role of pressing, positioning, and guiding the paper.

[0013] By adopting the above technical solution, the frame is equipped with multiple sets of extension rods, and each set of extension rods is equipped with a pressing wheel. After the paper passes through the limiting rod, it is pressed by the pressing wheel and cut by the cutting device. The pressing wheel plays a positioning and guiding role.

[0014] In summary, the present invention has the following main advantages: The first and second motors drive the cutting mechanism and the paper roll transmission system respectively, coordinating their actions to significantly improve production efficiency. The angle of the cutting device can be flexibly adjusted to adapt to different slitting needs, enhancing the applicability of the equipment. The combination of gears and transmission belts enables multi-rod synchronous rotation, ensuring uniform paper tension and stable transmission. The pressure wheel structure effectively guides and positions the paper, preventing deviation or loosening, and ensuring neat cutting and smooth winding. Attached Figure Description
