Description

Technical Field

[0001] This utility model relates to the field of slitting and connecting frame technology, specifically a printing press slitting and connecting frame. Background Technology

[0002] In the printing and processing industry, the paper conveying and slitting process after printing is a crucial step in ensuring finished product quality and production efficiency. Traditional printing presses often experience problems such as paper misalignment, uneven tension, and unstable conveying when connected to the slitting device. These issues can easily cause paper wrinkles, misalignment, or damage, thus affecting the precision and consistency of the final product.

[0003] Current slitting and connecting devices have relatively simple structures, mostly using a single paper feed roller or a combination of traction rollers, which fail to effectively control the dynamic deviation of the paper during operation. Furthermore, some devices are bulky and inconvenient to adjust, failing to meet the requirements of modern high-efficiency printing production lines for precise control and rapid adjustment.

[0004] In addition, existing printing presses lack multi-segment guiding structures in the paper transport path, making the paper prone to vibration and deviation when running at high speed. Furthermore, some devices fail to integrate a correction system, resulting in reduced subsequent slitting accuracy. In severe cases, it may even require shutdown and rework, affecting production capacity.

[0005] Therefore, there is an urgent need for a printing press slitting connector with a reasonable structure, high stability, and high-precision correction capability to improve the stability of paper feeding and the accuracy of slitting, and to meet the requirements of high-speed printing production. This paper proposes a printing press slitting connector to solve the above-mentioned technical problems. Utility Model Content

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. In the embodiments of the present utility model, the different types of cross-sectional lines are not labeled according to national standards, nor do they specify material requirements for the components; they are used to distinguish the cross-sectional views of the components in the drawings.

[0022] Please see Figure 1-4 A printing press slitting and connecting frame includes a first paper feed roller assembly 1. A support leg 2 is provided at the bottom of the slitting and connecting frame, and a base 8 is mounted on the upper end of the support leg 2. The first paper feed roller assembly 1 is located on the leftmost side of the upper end of the base 8. A pneumatic mechanism 3 is mounted on the right end of the first paper feed roller assembly 1. A second paper feed roller assembly 4 and a third paper feed roller assembly 6 are respectively provided on the right side of the pneumatic mechanism 3. A paper feed roller 5 is mounted on one side of the upper end of the second and third paper feed roller assemblies 4 and 3. A fourth paper feed roller assembly 7 is provided in the middle of the slitting and connecting frame, and a fifth paper feed roller assembly 9 is provided on the right end of the fourth paper feed roller assembly 7. A correction mechanism 11 is installed at the rightmost end of the slitting and connecting frame, and a sixth paper feed roller assembly 10 and a seventh paper feed roller assembly 12 are respectively provided on the left and lower right sides of the correction mechanism 11.

[0023] The paper feeding system consists of two sets of traction rubber rollers at the beginning and end and five sets of hard-anodized aluminum rollers in the middle. It is responsible for traction of the paper material to ensure the stability and precision of the paper material during the slitting process.

[0024] There are four outriggers in total.

[0025] The traction rollers employ a large-diameter double-roller traction paper path, ensuring stable paper transport.

[0026] The fourth paper feed roller assembly 7 is located between the third paper feed roller assembly 6 and the fifth paper feed roller assembly 9.

[0027] Among them, the edge position control type correction controller of the correction mechanism 11 is an EPC correction device. The drive unit of the EPC automatic correction device is a low-speed synchronous motor and a ball screw to ensure high-precision paper control.

[0028] It should be noted that the core of this printing press slitting connection frame lies in effectively connecting the printing output section with the subsequent slitting device through a rationally arranged paper guiding system and a precise deviation correction control system. This ensures that the paper is smoothly and efficiently transported from the printing end to the slitting end, maintaining the linearity of its running path and the consistency of its tension, thus ensuring the accuracy of the subsequent slitting process.

[0029] This device is installed between the printing press and the slitting machine. Its bottom is supported by four legs 2, which support the chassis 8 of the connecting frame, ensuring the device is stable and can withstand the vibration and load requirements of industrial production. The printed paper first enters the first paper feed roller assembly 1 located on the far left of the connecting frame. This assembly is mainly responsible for guiding the paper from the printing output port into this connecting frame system, completing the initial paper feed and positioning.

[0030] After the paper is drawn out from the first paper feed roller assembly 1, it enters the pneumatic mechanism 3 area on the right. This pneumatic mechanism includes a pressure regulating cylinder and a pressure spring system, which can automatically adjust the clamping force according to the paper thickness and conveying speed to ensure stable paper traction. Immediately following the pneumatic mechanism are the second paper feed roller assembly 4 and the third paper feed roller assembly 6, which are equipped with paper feed rollers 5, which are made of hard anodized aluminum. The tension is adjusted through the arc path between the aluminum rollers, which plays a role in buffering and guiding.

[0031] The paper further enters the fourth paper guide roller assembly 7 in the middle of the paper path. This assembly is located in the center of the paper path and plays a role in segmented tension control and maintaining tension in the middle of the paper path. Its right end connects to the fifth paper guide roller assembly 9. The combination of the two helps to form a "tension control zone" for the paper, ensuring balanced tension throughout the entire operation and avoiding shaking and skewing caused by high-speed conveying.

[0032] At this point, the paper has completed a series of guiding, traction, buffering, and tension adjustment processes, entering the rightmost control area of ​​the system, namely the web guiding mechanism 11. This mechanism adopts an EPC edge position control web guiding system, whose core control unit consists of a low-speed synchronous motor and a ball screw drive. When the web guiding sensor monitors the paper edge deviation in real time, the web guiding controller issues an adjustment command, driving the ball screw to adjust the offset angle of the sixth paper roller assembly 10, thereby achieving precise web guiding.

[0033] After correction, the paper enters the seventh paper roller assembly 12, which serves as the final exit roller. From there, the paper smoothly enters the slitting device, ready for cutting or slitting operations.

[0034] Throughout the entire process, the traction rollers at the beginning and end play a primary role in traction of the paper material in the first and seventh paper guide roller assemblies, working in conjunction with the five sets of aluminum paper guide rollers in the middle to complete precise guidance. The traction rollers adopt a double-roller clamping design, featuring large diameter and non-slip surface characteristics to ensure high traction strength and good adaptability. The aluminum rollers, through a reasonable arrangement, form a curved paper path, guiding the paper evenly through each station.

[0035] Through the above structure and coordination, the connecting frame can not only provide stable guidance during high-speed paper movement, but also actively adjust the paper path through a high-precision correction system, making the entire paper conveying process efficient and accurate, and providing a reliable foundation for subsequent slitting.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] 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.
