Description

Technical Field

[0001] This application belongs to the field of roll-to-roll machining technology, and in particular relates to a paper holder for a printing press for roll paper. Background Technology

[0002] In the current technical field of web printing presses, web printing presses, as printing equipment that uses web paper as the printing substrate, are widely used in the printing production of books, magazines, newspapers, etc. They typically consist of main components such as an unwinding section, a printing section, a drying section, a web guiding section, and a rewinding section. During operation, the web paper is conveyed from the unwinding section, clamped and fixed by the clamps on the paper rack, to the printing section for printing, then sequentially passes through the drying section and the web guiding section, and finally the finished product is collected in the rewinding section.

[0003] However, existing web-based printing presses present numerous inconveniences in the web-changing process. Web-based paper rolls are large and heavy, requiring workers to disassemble and reinstall parts of the feeding mechanism, such as the shaft, during replacement. This process is not only complex and tedious but also consumes a significant amount of time and manpower. On some web-based rotary printing presses, the used web-based paper roll must first be removed from the feeding mechanism before installing the new roll. The disassembly and reassembly of parts of the feeding mechanism during this process highlights the inconvenience of web-based paper changing. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this application is to provide a paper holder for a printing press for roll paper, which can solve the above-mentioned problems.

[0005] The purpose of this application is to provide a paper holder for a printing press for roll paper, comprising:

[0006] frame;

[0007] A support base is mounted on the frame, and the support base is provided with a placement slot;

[0008] Paper rollers are set on a placement trough;

[0009] A clamping seat is provided on a support base and is used to cooperate with the support base to fix the paper roller;

[0010] An adjustment device, mounted on the frame and connected to the clamping seat, is used to adjust the position of the clamping seat and to buffer the adjustment process.

[0011] The support base is also equipped with a driver for driving the paper roller to rotate.

[0012] The aforementioned paper holder for a web-fed printing press utilizes a frame as its support base, with slots on the support seat to hold the paper rollers. Combined with a clamping seat and adjusting device, it enables rapid fixing and releasing of the paper rollers. Compared to the complex operation of replacing paper rollers in existing technologies that require disassembling parts of the feeding mechanism, this application eliminates the need for disassembling other components. Paper roller replacement can be conveniently completed simply by adjusting the position of the clamping seat. Furthermore, the integrated driver on the support seat directly drives the paper roller rotation, improving overall operating efficiency. In addition, the modular design of each component in this application makes subsequent maintenance and repair of the paper holder more convenient, reducing maintenance costs.

[0013] Furthermore, the adjusting device includes:

[0014] The support structure includes a first plate body disposed on the frame, a second plate body slidably disposed on the first plate body, and a first cylinder installed at the bottom of the first plate body;

[0015] The linkage structure includes a horizontal plate hinged to the first plate and a linkage rod hinged to the horizontal plate. The other end of the linkage rod is hinged to the second plate, and a mounting bracket is installed at the bottom of the horizontal plate. The mounting bracket is connected to the clamping seat.

[0016] The adjustment device is installed on both sides of the frame.

[0017] In this application, the extension and retraction of the first cylinder can drive the second plate to slide up and down on the first plate, and under the action of the linkage rod, the horizontal plate can be rotated around the hinge point, causing the mounting bracket located at the bottom of the horizontal plate to rotate around the hinge point of the horizontal plate, thereby opening the clamping seat at the bottom of the mounting bracket. At this time, the paper roller can be taken out from the placement slot. After the replacement is completed, the first cylinder can be driven again.

[0018] In the support structure of the adjustment device, the first cylinder drives the second plate to slide on the first plate. The linkage structure, through the hinged cooperation of the horizontal plate and the linkage rod, converts linear motion into the rotation of the horizontal plate, thereby realizing the opening and closing of the clamping seat. Compared with the traditional fixed or complicated disassembly and assembly method of paper roller fixing, the operator only needs to control the extension and retraction of the first cylinder to quickly open the clamping seat and remove the paper roller from the placement slot; after replacement, the first cylinder is driven in reverse to quickly complete the reinstallation and fixing of the paper roller, which greatly shortens the roll paper change time, significantly improves the paper changing efficiency of the printing press, and reduces the intensity of manual operation.

[0019] In addition, the symmetrically arranged adjustment devices on both sides ensure that the pressure seat is subjected to uniform force, preventing the paper roller from tilting or falling during replacement. This not only improves the safety of operation, but also allows the paper holder to adapt to paper rollers of different diameters, thus improving the versatility of the paper holder.

[0020] Furthermore: the mounting bracket includes:

[0021] The frame has movable slots;

[0022] The second cylinder is located in the movable slot and its output shaft is connected to the clamping seat;

[0023] It also includes protective components, which are located on both sides of the movable groove and connected to the clamping seat.

[0024] Furthermore, limit guide grooves are provided on both sides of the movable groove, and guide blocks adapted to the limit guide grooves are provided on the clamping seat.

[0025] The mounting frame has a movable slot, within which a second cylinder connects to the clamping seat. This allows for precise control of the clamping seat's position, ensuring uniform pressure when fixing the paper roller and preventing damage due to uneven force. Simultaneously, limiting guide grooves on both sides of the movable slot cooperate with guide blocks on the clamping seat, ensuring a stable linear motion trajectory during its up-and-down movement, further enhancing the stability of the paper roller fixation. The presence of protective components effectively prevents damage to the support or paper roller from excessively rapid clamping seat adjustments. Furthermore, the combination of the limiting guide grooves and guide blocks also provides a certain degree of restraint on the clamping seat, preventing it from deviating from its predetermined track during adjustment, thus improving the reliability of the device's operation.

[0026] Furthermore, the protective component includes:

[0027] The damping component is located in the limiting guide groove, and its telescopic end is connected to the guide block.

[0028] A compression spring is disposed within the limiting guide groove and sleeved outside the damping component;

[0029] There are two damping components and two compression springs, which are symmetrically arranged on both sides of the movable groove.

[0030] The damping element and compression spring in the protective assembly are symmetrically arranged on both sides of the movable groove. When the clamping seat moves up and down, the damping element provides buffering resistance, slowing down the movement speed of the clamping seat, while the compression spring provides elastic support and reset. Working together, they ensure that the clamping seat runs smoothly during adjustment, preventing it from impacting the support seat or paper roller due to excessive speed. On the other hand, after the paper roller is replaced, the clamping seat can quickly and stably reset to the position where the paper roller is fixed, protecting both the paper roller and the support seat, and ensuring the reliability and efficiency of the paper roller fixing.

[0031] Furthermore, the support base is rotatably mounted on the frame, and a third cylinder is provided on the frame and hinged to the support base. The output shaft of the third cylinder is hinged to the end of the support base away from the frame.

[0032] The support base is rotatably mounted on the frame and driven by a third cylinder. When changing the paper roll, the third cylinder extends and retracts, causing the support base to rotate downwards. This, in conjunction with the adjusting device, opens the clamping seat upwards, further expanding the operating space for removing and installing the paper roll. This makes replacing larger paper rolls much easier, eliminating the need for operators to lift or move them laboriously, significantly reducing labor intensity. It also improves the safety and convenience of paper roll replacement. Compared to existing technologies, the coordinated operation of the support base rotation and the adjusting device makes the paper roll replacement process smoother, reducing the risk of equipment failure due to improper operation and improving the overall operational stability of the printing press.

[0033] The beneficial effects of this application are:

[0034] 1. The position of the clamping seat is controlled by the adjustment device, and the paper roller can be changed quickly without disassembling other parts. The support seat integrates a driver to directly drive the paper roller to rotate, which effectively improves the operating efficiency of the printing press.

[0035] 2. The symmetrical adjustment device on both sides can ensure that the pressure seat is evenly stressed. The mounting frame, together with the limiting guide groove and guide block, controls the position of the pressure seat. In addition, the damping component and compression spring in the protective component work together to buffer, ensuring that the paper roll is fixed stably and the device operates reliably.

[0036] 3. The support base is driven to rotate by the third cylinder, which, in conjunction with the adjustment device, expands the paper roller replacement space, reduces the intensity of manual operation and the difficulty of replacement, thereby reducing the risk of equipment failure and improving the overall stability and safety of the printing press.

[0044] The following description, in conjunction with the accompanying drawings, details the paper holder for a printing press for roll paper provided in this application through specific embodiments and application scenarios.

[0045] Example 1:

[0046] like Figures 1 to 3 As shown, this application provides a paper holder for a printing press for roll paper, comprising:

[0047] 100 racks;

[0048] A support base 200 is mounted on the frame 100, and a placement slot 210 is provided on the support base 200;

[0049] Paper roller 220 is disposed on placement groove 210;

[0050] A clamping seat 300 is disposed on a support seat 200 and is used to cooperate with the support seat 200 to fix the paper roller 220;

[0051] An adjustment device 400 is mounted on the frame 100 and connected to the clamping seat 300. It is used to adjust the position of the clamping seat 300 and can buffer the adjustment process.

[0052] The support base 200 is also equipped with a driver for driving the paper roller 220 to rotate.

[0053] In some embodiments of this application, such as Figure 1 As shown, the paper holder for a web-fed printing press employs the aforementioned design. By setting the frame 100 as the supporting base, and providing a placement groove 210 on the support base 200 to support the paper roller 220, the paper roller 220 can be quickly fixed and released using the clamping seat 300 and adjusting device 400. Compared to the complex operation of replacing the paper roller 220 in existing technologies that require disassembling parts of the feeding mechanism, this application eliminates the need to disassemble other components. The paper roller 220 can be easily replaced simply by controlling the position of the clamping seat 300 using the adjusting device 400. Simultaneously, the driver integrated on the support base 200 can directly drive the paper roller 220 to rotate, improving overall operating efficiency. Furthermore, the modular design of each component in this application makes subsequent maintenance and repair of the paper holder more convenient, reducing maintenance costs.

[0054] Example 2:

[0055] This application provides a paper holder for a printing press for roll paper. In addition to the above-mentioned technical features, the paper holder for a printing press for roll paper in this application also includes the following technical features.

[0056] like Figures 1 to 3 As shown, the adjusting device 400 includes:

[0057] The support structure includes a first plate 410 disposed on the frame 100, a second plate 420 slidably disposed on the first plate 410, and a first cylinder 430 installed at the bottom of the first plate 410.

[0058] The linkage structure includes a horizontal plate 440 hinged to the first plate 410, a linkage rod 450 hinged to the horizontal plate 440, the other end of the linkage rod 450 hinged to the second plate 420, and a mounting bracket 460 is also installed at the bottom of the horizontal plate 440, which is connected to the clamping seat 300.

[0059] The adjustment device 400 is provided on both sides of the frame 100.

[0060] In this application, the extension and retraction of the first cylinder 430 can drive the second plate 420 to slide up and down on the first plate 410, and under the action of the linkage rod 450, the horizontal plate 440 is driven to rotate around the hinge point, causing the mounting bracket 460 located at the bottom of the horizontal plate 440 to rotate around the hinge point, thereby opening the clamping seat 300 at the bottom of the mounting bracket 460. At this time, the paper roller 220 can be taken out from the placement slot 210. After the replacement is completed, the first cylinder 430 can be driven again.

[0061] In this embodiment, in the support structure of the adjusting device 400, the first cylinder 430 drives the second plate 420 to slide on the first plate 410. The linkage structure, through the hinged cooperation of the horizontal plate 440 and the linkage rod 450, converts linear motion into rotation of the horizontal plate 440, thereby realizing the opening and closing of the pressing seat 300. Compared with the traditional fixed or complex disassembly and assembly method of fixing the paper roller 220, the operator only needs to control the extension and retraction of the first cylinder 430 to quickly open the pressing seat 300 and take out the paper roller 220 from the placement slot 210. After replacement, the first cylinder 430 is driven in reverse to quickly complete the reinstallation and fixing of the paper roller 220, which greatly shortens the roll paper replacement time, significantly improves the paper changing efficiency of the printing press, and reduces the intensity of manual operation.

[0062] In addition, the symmetrically arranged adjustment devices 400 on both sides ensure that the pressure seat 300 is subjected to uniform force, preventing the paper roller 220 from tilting or falling during replacement. This not only improves the safety of operation, but also allows the paper rack to adapt to paper rollers 220 of different diameters, thus improving the versatility of the paper rack.

[0063] Example 3:

[0064] This application provides a paper holder for a printing press for roll paper. In addition to the above-mentioned technical features, the paper holder for a printing press for roll paper in this application also includes the following technical features.

[0065] like Figures 1 to 4 As shown, the mounting bracket 460 includes:

[0066] The frame 461 has a movable slot 462;

[0067] The second cylinder 463 is located in the movable groove 462 and its output shaft is connected to the clamping seat 300;

[0068] It also includes a protective component 470, which is disposed on both sides of the movable groove 462 and connected to the clamping seat 300.

[0069] Furthermore, limit guide grooves 464 are provided on both sides of the movable groove 462, and guide blocks 465 adapted to the limit guide grooves 464 are provided on the clamping seat 300.

[0070] In this embodiment, the frame 461 of the mounting bracket 460 has a movable groove 462. The second cylinder 463 is located in the movable groove 462 and connected to the clamping seat 300, enabling precise control of the position of the clamping seat 300. This ensures uniform pressure on the clamping seat 300 when fixing the paper roller 220, preventing damage to the paper roller 220 due to uneven force. Simultaneously, the limiting guide grooves 464 on both sides of the movable groove 462 cooperate with the guide blocks 465 on the clamping seat 300, ensuring that the clamping seat 300 maintains a stable linear motion trajectory during its up-and-down movement, further enhancing the stability of the paper roller 220. Furthermore, the presence of the protective component 470 effectively prevents damage to the support seat 200 or the paper roller 220 caused by excessively rapid adjustment of the clamping seat 300. In addition, the cooperation of the limiting guide grooves 464 and the guide blocks 465 also provides a certain limiting effect on the clamping seat 300, preventing it from deviating from the predetermined track during adjustment and improving the reliability of the device operation.

[0071] Example 4:

[0072] This application provides a paper holder for a printing press for roll paper. In addition to the above-mentioned technical features, the paper holder for a printing press for roll paper in this application also includes the following technical features.

[0073] like Figure 4 As shown, the protective component 470 includes:

[0074] Damping element 471 is disposed in limiting guide groove 464, and its telescopic end is connected to guide block 465;

[0075] Compression spring 472 is disposed in limiting guide groove 464 and sleeved on the outside of damping component 471;

[0076] Two damping elements 471 and two compression springs 472 are provided, and the two damping elements 471 and the two compression springs 472 are symmetrically arranged on both sides of the movable groove 462.

[0077] In this embodiment, the damping element 471 and compression spring 472 in the protective assembly 470 are symmetrically arranged on both sides of the movable groove 462. When the pressing seat 300 moves up and down, the damping element 471 provides buffer resistance to slow down the movement speed of the pressing seat 300, while the compression spring 472 plays the role of elastic support and reset. The two work together to ensure that the pressing seat 300 runs smoothly during the adjustment process, preventing it from hitting the support seat 200 or paper roller 220 due to excessive speed. On the other hand, after the paper roller 220 is replaced, the pressing seat 300 can be quickly and stably reset to the position where the paper roller 220 is fixed, which protects the paper roller 220 and the support seat 200, and ensures the reliability and efficiency of the paper roller 220 fixing.

[0078] Example 5:

[0079] This application provides a paper holder for a printing press for roll paper. In addition to the above-mentioned technical features, the paper holder for a printing press for roll paper in this application also includes the following technical features.

[0080] like Figure 3 As shown, the support base 200 is rotatably mounted on the frame 100. The frame 100 is provided with a third cylinder 230 that is hinged to the support base 200. The output shaft of the third cylinder 230 is hinged to the end of the support base 200 away from the frame 100.

[0081] In this embodiment, the support base 200 is rotatably mounted on the frame 100 and driven by the third cylinder 230. When changing the paper roller 220, the third cylinder 230 extends and retracts, causing the support base 200 to rotate downwards. This, in conjunction with the adjusting device 400, opens the clamping seat 300 upwards, further expanding the operating space for removing and installing the paper roller 220. This makes replacing the larger paper roller 220 easier and less strenuous, eliminating the need for operators to lift or move it, significantly reducing labor intensity. It also improves the safety and convenience of replacing the paper roller 220. Compared to existing technologies, the coordinated operation of the support base 200 and the adjusting device 400 during rotation makes the paper roller 220 replacement process smoother, reducing the risk of equipment failure due to improper operation and improving the overall operational stability of the printing press.
