Description

Technical Field

[0001] This utility model relates to the field of slitting mechanism technology, specifically a novel slitting mechanism for a printing line slitting machine. Background Technology

[0002] With the rapid development of the packaging and printing industry, the slitting technology for various roll materials such as films, tapes, copper foil, and aluminum foil is constantly demanding higher standards, especially in terms of printing positioning accuracy and slitting efficiency. This requires slitting devices to have higher automation capabilities and more convenient tool changing operations. Currently, most slitting devices on the market use fixed blade shafts or simple sliding rail structures. When changing blades or setting them, manual tightening and loosening of fixing parts, disassembly of components, or the use of special tools are often required. This is not only inefficient but also prone to errors, affecting the stability and repeatability of the equipment.

[0003] Furthermore, traditional blade holders often suffer from low adjustment accuracy, inconvenient adjustment, and unstable operation when adjusting height due to poor rigidity of the transmission structure or unreasonable control methods. Especially during high-speed operation, the vibration of the blade holder can affect the slitting quality, causing burrs on material edges, misalignment, or even blade damage. Therefore, developing a slitting mechanism with a simple structure, quick adjustment, convenient blade replacement, and automatic reset function has become a key technological direction for improving the performance of slitting equipment.

[0004] The purpose of this utility model is to provide a new slitting mechanism for a wire printing slitting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel slitting mechanism for a printing line slitting machine includes a first paper feed roller assembly and a blade holder roller. The blade holder roller is movably mounted on a swing arm and can be easily removed from the swing arm. The swing arm is movably mounted on a support column fixed to a main support by bolts. The swing arm is movably connected to a cylinder via a connecting rod. The cylinder is fixed to an L-shaped support connected to the main support. A pneumatic push rod switch controls the retraction of the connecting rod of the pneumatic push rod, driving the blade holder roller to rotate and increase the distance between the blade holder roller and the transmission roller, thereby facilitating the replacement of the circular blade and blade setting. The leftmost end of the slitting mechanism is provided with the first paper feed roller assembly, and the rightmost end of the slitting mechanism is provided with a second paper feed roller assembly and a third paper feed roller assembly. A cylinder long pin is provided on the left side of the cylinder and is connected to the L-shaped support via the cylinder long pin. A spherical bearing with a boss is provided on the side that drives the blade holder roller. A roller seat is provided at the upper end of the second paper feed roller assembly. The swing arm is connected via a short pin via a connecting rod.

[0007] Preferably, the tool holder roller can be quickly removed from the swing arm via a pin structure, making it convenient for operators to replace the circular tool or clean the tool shaft without using tools.

[0008] Preferably, one end of the swing arm is rotatably connected to the connecting rod via a short pin, and the other end is mounted on the support column via a rolling hinge, so as to ensure the flexibility of the swing arm movement and the positioning accuracy of the cutter shaft.

[0018] Please see Figure 1-2 A novel slitting mechanism for a printing line slitting machine includes a first paper feed roller assembly 1 and a blade holder roller 13. The blade holder roller 13 is movably mounted on a swing arm 9 and can be easily removed from the swing arm 9. The swing arm 9 is movably mounted on a support column fixed to the main support by bolts. The swing arm 9 is movably connected to a cylinder 5 via a connecting rod 8. The cylinder 5 is fixed to an L-shaped support 12 connected to the main support. The connecting rod 8 of the pneumatic push rod is retracted by a pneumatic push rod switch, which drives the blade holder roller 13 to rotate, thereby increasing the displacement of the blade holder roller 13 relative to the paper feed roller. The spacing of the moving rollers facilitates the replacement of the circular blade 11 and blade setting. The leftmost end of the slitting mechanism is provided with the first paper feed roller assembly 1, and the rightmost end of the slitting mechanism is provided with the second paper feed roller assembly 2 and the third paper feed roller assembly 3. The left side of the cylinder 5 is provided with the cylinder long pin 4, which is connected to the L-shaped support 12. The side of the drive blade holder roller 13 is provided with a circular seat outer spherical bearing 6 with a boss. The upper end of the second paper feed roller assembly 2 is provided with a roller seat 7. The swing arm 9 is connected by the connecting rod 8 and the short pin 10.

[0019] The tool holder roller 13 can be quickly removed from the swing arm 9 via a pin structure, making it easy for operators to replace the circular cutter 11 or clean the tool shaft without using tools.

[0020] One end of the swing arm 9 is rotatably connected to the connecting rod 8 via a short pin 10, and the other end is mounted on the support column via a rolling hinge to ensure the flexibility of the swing arm movement and the positioning accuracy of the cutter shaft.

[0021] Among them, connecting rod 8 is made of high-strength aluminum alloy.

[0022] The L-shaped support 12 is fixed to the main support by thread or welding.

[0023] The second paper feed roller assembly 2 is provided with an adjustable roller seat 7 at its upper end, which is used to adjust the height and angle of the guide roller to adapt to the paper feeding path of materials of different thicknesses.

[0024] It should be noted that the core of the novel slitting mechanism described in this invention lies in the controllable rotational adjustment of the blade holder roller through the linkage of the swing arm structure and the cylinder drive system, facilitating quick replacement of the circular blade and precise adjustment of the cutting blade position. The following is a detailed description of the operation and control process:

[0025] Before the slitting operation begins, the roll material enters the slitting area through the first paper feed roller assembly 1. During the slitting process, the paper strip is supported by the second and third paper feed roller assemblies 2 and 3, which guide the paper strip along a set path to the circular blade 11 equipped on the blade holder roller 13 to complete the slitting operation.

[0026] The tool holder roller 13 is detachably mounted on the swing arm 9. This mounting method ensures that the tool shaft can be easily removed from the swing arm when the round tool needs to be replaced or adjusted, without the need for complicated tools, saving maintenance time. The swing arm 9 is hinged to the connecting rod 8 via a short pin 10, and its other end is connected to the main bracket via a support column, thus realizing the swing function.

[0027] Cylinder 5 is fixed to L-shaped support 12 via cylinder long pin 4. L-shaped support is welded or screwed to the main support body, forming a stable installation base. Cylinder 5 controls the extension and retraction of connecting rod 8. When a signal is sent through the pneumatic control system, the piston rod of the cylinder will perform a corresponding action. Connecting rod 8 drives the swing arm 9 at short pin 10 to rotate, and the tool holder roller 13 then moves in an arc around the fixed axis, thereby changing the relative distance between the circular tool and the material.

[0028] When it is necessary to change or set the circular cutter, the operator activates the pneumatic switch, controlling the cylinder 5 to retract. The connecting rod 8 then drives the swing arm 9 to rotate, moving the cutter holder roller 13 away from the transmission roller, leaving sufficient space for operation. After the change is completed, the control switch is activated again, the cylinder pushes out the piston, the swing arm resets, and the cutter holder roller 13 returns to its original cutting position. The entire process requires no manual intervention.

[0029] To ensure that the tool holder roller 13 maintains good coaxiality and support rigidity during movement, a spherical bearing 6 with a boss on one side is provided. This structure not only has a self-aligning function, but also buffers axial and radial runout caused by movement, thereby improving operating accuracy and service life.

[0030] In the entire slitting structure, the first paper guide roller assembly 1, the second paper guide roller assembly 2, and the third paper guide roller assembly 3 serve as auxiliary guiding devices to ensure that the paper strip remains taut and stable on the path before entering the circular knife, avoiding the impact of deviation or slack on slitting accuracy. The second paper guide roller assembly 2 is equipped with a roller seat 7 on its upper part, which can be used as a fixed or adjustable support to further optimize the paper strip's feeding posture.

[0031] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
