Description

Technical Field

[0001] This utility model belongs to the technical field of slitting mechanisms, specifically relating to a width-adjustable slitting mechanism. Background Technology

[0002] The slitting mechanism of the die-cutting equipment is the core functional module that enables precise segmentation of materials in the width direction. It cuts continuous rolls or sheets into multiple independent materials according to a preset width through the shearing, squeezing or cutting action of the blades, while ensuring that the slitting edges are flat and the dimensional accuracy meets the process requirements.

[0003] However, when the current die-cutting equipment is in use, it can usually only cut materials of a specific width. When the cutting width needs to be adjusted during production, the operator must stop the machine, disassemble and replace the cutting blade or mechanism components as a whole. Not only is the operation process cumbersome, but each replacement often takes tens of minutes, which seriously affects the continuity of production and the utilization rate of equipment, resulting in a significant reduction in work efficiency and making it difficult to meet the needs of modern production for small batches and rapid switching of multiple specifications.

[0004] To address the aforementioned issues, this application proposes a width-adjustable slitting mechanism. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a width-adjustable slitting mechanism, comprising a frame, a controller mounted on the top of the frame, an electric push rod snapped onto the upper surface of the frame, two slotted frames fixedly connected to the inner wall of the frame, a threaded rod rotatably connected to the inner wall of each slotted frame, two sets of sliding frames slidably connected inside each slotted frame, the inner wall of each set of sliding frames threadedly connected to the outer surface of the threaded rod, a brake motor mounted on the front of each slotted frame, and the power output end of each brake motor connected to... The threaded rod is fixedly connected to one end near the controller. Each set of sliding frames is fixedly connected to a connecting frame on one side that is close to each other. Each connecting frame is equipped with a telescopic spring inside. The inner walls of each set of connecting frames are slidably connected to a connecting plate. The bottom end of each set of telescopic springs is fixedly connected to the upper surface of the connecting plate. A cutting blade is provided below each connecting plate. An iron block is fixedly connected to the upper surface of each connecting plate. An electromagnet is fixedly connected to the telescopic end of the electric push rod. The bottom surface of the electromagnet is in contact with the upper surface of one of the iron blocks.

[0007] As a preferred embodiment of this utility model, a transparent plate is snapped onto the left side of the frame, a reinforcing frame is fixedly connected to the outer surface of the transparent plate, and the right side of the reinforcing frame is fixedly connected to the left side of the frame.

[0008] As a preferred embodiment of this utility model, the bottom surface of the frame is fixedly connected to two support frames, and each support frame is provided with two fixing pins inside.

[0009] As a preferred embodiment of this utility model, a fixing ring is fixedly connected to the outer surface of the electric push rod, and the bottom surface of the fixing ring is fixedly connected to the upper surface of the frame.

[0010] As a preferred embodiment of this utility model, the bottom surface of the controller is fixedly connected to a mounting plate, and the bottom surface of the mounting plate is fixedly connected to the upper surface of the frame.

[0011] As a preferred technical solution of this utility model, the two brake motors are fixedly connected to a fixing frame on the side that is close to each other, and the two fixing frames are fixedly connected to the inner wall of the frame body on the side that is far apart from each other.

[0012] As a preferred embodiment of this utility model, a connecting ring is fixedly connected to the top of each telescopic spring, and the upper surface of each connecting ring is fixedly connected to the inner top wall of the connecting frame.

[0013] As a preferred embodiment of this utility model, a fixing block is fixedly connected to the bottom surface of each connecting plate, and the bottom surface of each fixing block is fixedly connected to the upper surface of the slitting blade.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a controller, the equipment can be started and stopped and adjusted in both directions. At the same time, the elastic force of the telescopic spring can be used to store the unused connecting plate and slitting blade in the connecting frame. The rotation of the brake motor can drive the threaded rod to rotate, and at the same time, the sliding frame can slide in the slot frame. Thus, according to the required width of the slitting blade, the appropriate connecting frame, telescopic spring, connecting plate and slitting blade can be moved to the bottom of the electric push rod. Then, through the cooperation of the electromagnet and the iron block, the electric push rod is connected to the corresponding connecting frame and slitting blade. The extension and retraction of the electric push rod drives the slitting blade to slide in the connecting frame. At the same time, the telescopic spring extends and retracts synchronously to realize the cutting action of the slitting blade. Since the width of each group of slitting blades is different, the above structure can realize the flexible adjustment of the slitting width of the slitting mechanism. Attached Figure Description

In this embodiment, the viewing plate 3 can be fixed to the frame 1 by the reinforcing frame 2, and the interior of the frame 1 can be easily observed by using the viewing plate 3.

[0027] Specifically, the bottom surface of the frame 1 is fixedly connected to two support frames 4, and each support frame 4 is provided with two fixing pins 5 inside. In this embodiment, the frame 1 can be supported on the die-cutting equipment through the support frames 4, and the support frames 4 can be fixed to the frame 1 by using the fixing pins 5.

[0028] Specifically, a fixing ring 7 is fixedly connected to the outer surface of the electric push rod 6. The bottom surface of the fixing ring 7 is fixedly connected to the upper surface of the frame 1. In this embodiment, the electric push rod 6 can be reinforced to the frame 1 through the fixing ring 7, thereby making the electric push rod 6 sturdy.

[0029] Specifically, the bottom surface of the controller 9 is fixedly connected to the mounting plate 8, and the bottom surface of the mounting plate 8 is fixedly connected to the upper surface of the frame 1. In this embodiment, the controller 9 can be fixed by the mounting plate 8.

[0030] Specifically, the two brake motors 13 are fixedly connected to a fixing bracket 15 on the side that is close to each other, and the two fixing brackets 15 are fixedly connected to the inner wall of the frame 1 on the side that is far from each other. In this embodiment, the brake motors 13 can be fixed by the fixing brackets 15. At the same time, the brake motor 13 refers to a special motor that integrates an electromagnetic brake device at the tail of the motor. Its core feature is that it realizes the braking function when the power is cut off by electromagnetic brake.

[0031] Specifically, each telescopic spring 17 is fixedly connected to a connecting ring 16 at its top end. The upper surface of each connecting ring 16 is fixedly connected to the inner top wall of the connecting frame 11. In this embodiment, the telescopic spring 17 can be fixed to the connecting frame 11 through the connecting ring 16, thereby enabling the telescopic spring 17 to be used stably.

In this embodiment, the slitting blade 22 can be fixed to the connecting plate 18 through the fixing block 21, and the slitting blade 22 can be used stably.

[0033] The working principle and usage process of this utility model are as follows: First, the target cutting width is input through the controller 9. The PLC system calculates the position of the corresponding cutting blade 22. The brake motor 13 drives the threaded rod 10 to rotate, causing the sliding frame 14 to slide within the slot frame 12. This moves the connecting frame 11, connecting plate 18, and cutting blade 22 laterally to directly below the electric push rod 6. After the electric push rod 6 extends, the electromagnet 19 is attracted to the iron block 20. At this time, the telescopic spring 17 is in a compressed state. The material is fed into the cutting area by the die-cutting equipment conveying system. The controller 9 starts the electric push rod 6, driving the cutting blade 22 to complete the lifting and lowering. During the cutting action, the telescopic spring 17 extends and retracts synchronously. When the cutting width needs to be switched, the electromagnet 19 is de-energized and separates from the iron block 20. The brake motor 13 rotates forward or in reverse to move the target cutting blade 22 to the electric push rod 6 to repeat the docking process. The unused cutting blade 22 is stored in the connecting frame 11 under the elastic force of the telescopic spring 17. This mechanism is installed on the die-cutting equipment frame through the support frame 4 and the fixed pin 5. It is linked with the guide rollers and tension control equipment of the conveying system. The photoelectric sensor monitors the material position in real time to ensure cutting accuracy and is synchronized with the material conveying, thereby improving the working efficiency of the equipment.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
