Description

Technical Field

[0001] This utility model relates to the field of printing and processing equipment technology, specifically to a high-precision positioning printing and slitting integrated machine. Background Technology

[0002] A printing and slitting machine is a processing device used to longitudinally slit and rewind printed roll materials. It is widely used in label printing, packaging materials, and self-adhesive paper products. Existing printing and slitting equipment is prone to lateral deviation of materials during the material conveying process due to factors such as wide material width, uneven tension, or guide roller parallelism errors. If the material deviates before entering the slitting process, it will lead to inaccurate slitting position, skewed edges, and even a large amount of waste, seriously affecting slitting accuracy and product yield.

[0003] To address these issues, existing technologies employ deviation correction devices to guide material movement. For example, a deviation correction controller is installed at the input of the slitting machine, using a positioning photoelectric sensor to detect the material's edge position and adjust it in conjunction with the deviation correction mechanism. However, existing deviation correction structures often use a swing frame adjustment method, resulting in a relatively complex overall structure. Furthermore, the integration between the swing fulcrum and the support structure during the deviation correction process is low, affecting the accuracy of the deviation correction response and the structural stability.

[0004] Furthermore, traditional slitting equipment typically employs a horizontal, straight-line material conveying path, meaning the material enters the slitting station horizontally from the input end and exits horizontally after slitting. While this layout is simple in structure, the equipment occupies a large amount of space, making it inconvenient to arrange in factory spaces with limited space. Additionally, waste tends to accumulate below the slitting station, making cleaning difficult.

[0005] Therefore, how to further improve the correction accuracy and structural compactness of the printing and slitting machine, while optimizing the material conveying path to reduce the equipment footprint, is a technical problem that needs to be solved in this field. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a high-precision positioning printing and slitting integrated machine with high-precision correction function and compact conveying layout, which addresses the shortcomings of existing printing and slitting equipment such as complex correction structure, insufficient precision and large equipment space occupation.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a high-precision positioning printing and slitting integrated machine, including a slitting device, and further including:

[0008] A correction device is installed at the input end of the slitting device. The correction device includes a lower fixed frame, a detection roller, a sensor, an upper moving frame, and a correction controller.

[0009] The detection roller is fixed to one side of the output end of the lower fixed frame and is used to support the conveyed material;

[0010] The sensor is configured correspondingly to the detection roller and is used to detect the positional deviation of the material edge and output a signal.

[0011] The upper movable frame is movably disposed on the upper side of the lower fixed frame, and the inner side of the upper movable frame is provided with a correction roller for correcting the material deviation.

[0012] The correction controller drives the upper moving frame to swing relative to the lower fixed frame based on the signal from the sensor.

[0013] The input end of the slitting device is located at the bottom of one side of the slitting device and is connected to the output end of the correction device.

[0014] The output end of the slitting device is located on the top of the other side of the slitting device, forming a material conveying path from bottom to top.

[0015] Preferably, the sensor is slidably disposed along the axial direction of the detection roller via a first guide assembly.

[0016] Preferably, the output end of the slitting device is provided with an upper cutter roller seat and a lower cutter roller seat. A steel roller and a traction roller are arranged in sequence on the rear side of the lower cutter roller seat. A paperboard is provided between the steel roller and the lower cutter roller seat, and between the steel roller and the traction roller. The lower cutter roller seat, the steel roller, the traction roller and the paperboard are located on the same horizontal plane.

[0017] Preferably, the steel roller is independently equipped with a fixed rubber roller that cooperates with it, and the traction roller is independently equipped with a movable rubber roller that cooperates with it. The movable rubber roller is provided with an adjustment component for adjusting the distance between the movable rubber roller and the traction roller.

[0018] Preferably, the lower side of the traction roller is provided with a slitting shaft and multiple sets of slitting blades, the upper side of the slitting shaft is provided with a second guide assembly, and the multiple sets of slitting blades are arranged on the second guide assembly and their positions can be adjusted along the axial direction of the slitting shaft.

[0019] Preferably, a third guide assembly is provided on the lower side of the cutting shaft, and the third guide assembly is provided with multiple slitting suction heads for absorbing the waste generated during cutting.

[0020] Preferably, an inlet roller is provided on the lower side of the slitting shaft, and the inlet roller is connected to the output end of the correction device to guide the material between the slitting shaft and the slitting blade.

[0021] Preferably, the lower fixed frame is provided with a correction support shaft between its input end side and the upper moving frame. The correction support shaft and the correction controller jointly support the upper moving frame, and the upper moving frame swings around the correction support shaft during correction.

[0022] The beneficial effects of this utility model are:

[0023] 1. By setting the correction device at the input end of the slitting device, the sensor detects the positional deviation of the material edge in real time, and the correction controller drives the upper frame to swing around the correction support shaft. The correction roller actively corrects the material, which effectively improves the conveying accuracy of the material before entering the slitting process and reduces the slitting skew and waste caused by the material running off track.

[0024] 2. By placing the input end of the slitting device at the bottom of one side and the output end at the top of the other side, a material conveying path is formed from bottom to top, making the overall layout of the equipment more compact, reducing the horizontal space occupation, and making it easier to arrange and use in production sites with limited space.

[0025] 3. By setting up a slitting suction head to actively pick up the waste material generated after slitting by the slitting knife, the waste material is prevented from accumulating at the slitting station and affecting the subsequent slitting quality, thereby improving the continuous operation capability and cleanliness of the equipment.

[0030] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example

[0031] like Figures 1 to 3The high-precision positioning printing and slitting integrated machine shown mainly includes three parts: a printing machine (not shown in the figure), a correction device 1, and a slitting device 2. The printing machine (not shown in the figure), the correction device 1, and the slitting device 2 are connected in sequence. The material is first printed by the printing machine (not shown in the figure), then the position is corrected by the correction device 1, and finally it enters the slitting device 2 to complete the slitting.

[0032] The correction device 1 is installed at the input end of the slitting device 2 and is used to correct the lateral position of the material before it enters the slitting process. The input end of the correction device 1 is connected to the output end of the printing press (not shown in the figure). The correction device 1 mainly consists of a lower fixed frame 3, a detection roller 4, a sensor 5, an upper moving frame 6, and a correction controller 7.

[0033] The lower frame 3 serves as the basic support structure for the correction device 1 and is fixedly installed on the machine frame. The detection roller 4 is fixed to one side of the output end of the lower frame 3, that is, the end closest to the slitting device 2. The axis of the detection roller 4 is perpendicular to the material conveying direction. When the material passes over the detection roller 4 from above, the detection roller 4 supports and guides the material.

[0034] Sensor 5 is positioned corresponding to detection roller 4, specifically installed on the front side of detection roller 4, to detect the real-time position of the material edge. When the material deviates laterally during conveying, sensor 5 can detect the deviation between the actual position of the material edge and the preset reference position, and output the deviation signal to the correction controller 7. Sensor 5 is mounted via the first guide assembly 9 and can slide along the axial direction of detection roller 4 to adjust its position to accommodate materials of different widths.

[0035] The upper moving frame 6 is movably mounted above the lower fixed frame 3 and can swing relative to the lower fixed frame 3. Several correction rollers 8 are provided on the inner side of the upper moving frame 6. The axis of the correction rollers 8 is parallel to the detection roller 4, and the material passes through the correction rollers 8 before entering the detection roller 4. After receiving the deviation signal output by the sensor 5, the correction controller 7 drives the upper moving frame 6 to swing relative to the lower fixed frame 3 at a corresponding angle according to the signal magnitude and direction. This causes the material to move laterally through the correction rollers 8, thus achieving active correction of material deviation.

[0036] The lower fixed frame 3 is provided with a correction support shaft 10 between its input end side and the upper moving frame 6. The correction support shaft 10 and the correction controller 7 jointly support the upper moving frame 6, forming a stable two-point support structure. During the correction process, the upper moving frame 6 uses the correction support shaft 10 as the swing fulcrum, and the other end of the upper moving frame 6 is driven by the correction controller 7 to swing, thereby achieving a smooth and precise correction action.

[0037] The input end of the slitting device 2 is located at the bottom of one side of the slitting device 2 and is connected to the output end of the correction device 1; the output end of the slitting device 2 is located at the top of the other side of the slitting device 2, thus forming a bottom-up material conveying path. This layout increases the overall height of the equipment while shortening the horizontal depth, effectively reducing the equipment's footprint.

[0038] The output end of the slitting device 2 is provided with an upper cutter roller seat 11 and a lower cutter roller seat 12. A steel roller 13 and a traction roller 14 are sequentially arranged on the rear side of the lower cutter roller seat 12. A paper guide 15 is provided between the steel roller 13 and the lower cutter roller seat 12, and between the steel roller 13 and the traction roller 14. The lower cutter roller seat 12, steel roller 13, traction roller 14, and paper guide 15 are located on the same horizontal plane, forming a horizontal material transition platform to ensure stable material transport before and after slitting.

[0039] The steel roller 13 is independently equipped with a fixed rubber roller 16 that cooperates with it, and the traction roller 14 is independently equipped with a movable rubber roller 17 that cooperates with it. The movable rubber roller 17 is provided with an adjustment component 18, which can adjust the distance between the movable rubber roller 17 and the traction roller 14 to adapt to materials of different thicknesses and ensure that the clamping force of the material is uniform and appropriate during the cutting process.

[0040] The traction roller 14 has a slitting shaft 19 and a multi-component cutter 20 on its lower side. The slitting shaft 19 has a second guide assembly 21 on its upper side, and the multi-component cutter 20 is mounted on the second guide assembly 21. Each cutter 20 can be independently adjusted in position along the axial direction of the slitting shaft 19 to meet the production requirements of different slitting widths.

[0041] A third guide assembly 22 is provided on the lower side of the slitting shaft 19, and a multi-part slitting suction head 23 is provided on the third guide assembly 22. The slitting suction head 23 is used to actively pick up the waste strips generated after the slitting blade 20 and the slitting shaft 19 are slitting, so as to prevent the accumulation of waste from affecting the subsequent slitting quality.

[0042] A guide roller 24 is also provided on the lower side of the slitting shaft 19. The guide roller 24 is located below the slitting shaft 19 and is connected to the output end of the correction device 1. After the material is output from the correction device 1, it is conveyed upward through the guide roller 24 into the space between the slitting shaft 19 and the slitting blade 20 to complete the slitting process.

[0043] The working process of this embodiment is as follows: After the material is printed by the printing press (not shown in the figure), it enters the correction device 1 and is guided forward by the correction roller 8 and the detection roller 4. The sensor 5 detects the edge position of the material in real time. When the material is detected to be deviating, the signal is transmitted to the correction controller 7. The correction controller 7 drives the upper frame 6 to swing around the correction support shaft 10 and corrects the lateral position of the material through the correction roller 8. After correction, the material is introduced from the bottom of the slitting device 2 by the inlet roller 24 and enters from bottom to top between the slitting shaft 19 and the slitting blade 20 to complete the longitudinal slitting. The slitting material continues to rise to the steel roller 13 and the traction roller 14 and is clamped and conveyed by the fixed rubber roller 16 and the movable rubber roller 17. Finally, it is output after being slitted by the upper blade roller seat 11 and the lower blade roller seat 12. The waste strips generated during the slitting process are sucked up and discharged in real time by the slitting suction head 23.
