Description

Technical Field

[0001] The present invention relates to the field of modern printing and conveying technologies, and particularly to a printing paper preparation production processing device and a processing method thereof. Background Art

[0002] In the modern printing industry, high-speed and high-quality paper preparation and production processing are the keys to improving production efficiency and product quality. With the continuous development of printing technologies, higher requirements are put forward for links such as paper conveying, positioning, and guiding. How to ensure the smooth conveying of paper under high-speed operating conditions and achieve precise control of the paper position is an important issue faced in the field of printing equipment design and manufacturing.

[0003] Currently, the paper conveying devices widely adopted in the industry mainly include paper feeding wheels and guiding devices. Among them, the paper feeding wheels drive and convey the paper through the frictional force with the paper surface. The guiding device restricts and guides the paper edge to ensure that the paper advances smoothly along a predetermined path. However, under high-speed operating conditions, these traditional paper conveying devices have some deficiencies. For example, when there are local wrinkles or deformations on the paper surface, the contact state between the paper feeding wheel and the paper changes, which easily causes slipping or damage to the paper surface.

[0004] In summary, the existing production processing devices mainly have the following disadvantages: 1. Due to the uneven pressure distribution between the paper feeding wheel and the paper, local deformations of the paper cannot be effectively suppressed and corrected, further increasing the risk of wrinkles and damage.

[0005] 2. In terms of paper positioning, the existing technologies usually use simple limit blocks or guiding plates to achieve the control of the paper position. Although this method has a simple structure, during high-speed operation, the collision and friction between the paper and the positioning device easily cause wear and deformation of the paper edge, affecting the positioning accuracy. In addition, these positioning devices usually lack flexibility and adaptability, and it is difficult to adapt to the switching requirements of different sizes and types of paper. A large amount of manual adjustment is required during format change, resulting in low efficiency.

[0006] 3. The existing technologies adopt elastic paper feeding wheels or airbag paper pressing devices in order to improve the adhesion between the paper feeding wheel and the paper and reduce the damage to the paper. Summary of the Invention

[0007] In view of this, the present invention provides a printing paper preparation production processing device and a processing method thereof, which have a channel module and can flexibly adjust the overall size of the channel according to different paper sizes.

[0008] The present invention provides a printing paper preparation production processing device and its processing method, specifically including: a channel module, the channel module adopts an aluminum alloy profile frame structure, the frame is composed of four profiles connected by corner codes, the cross-section of the profile is 40mm×40mm, the wall thickness is 2mm, positioning blocks for assembly are staggered on the outer edge of the channel module, and a handle is fixedly arranged in the middle of the outside of the channel module; notches are opened at the inlet and outlet of the channel formed by the channel module; two groups of guide plates are rotatably arranged at the entrance of the channel module; a handwheel is arranged outside the rotating shaft of the guide plate, and the rotating shaft is locked by a setscrew; an L-shaped limit block for limiting the guide plate is fixedly arranged on the side of the entrance of the channel module; a flexible paper feeding wheel and a metal paper pressing wheel are rotatably arranged in the channel module, and the flexible paper feeding wheel and the metal paper pressing wheel are staggered.

[0009] Optionally, an upper positioning block is fixedly arranged on the inner side of the channel module, a lower positioning block is slidably arranged on one side of the upper positioning block in cooperation with a spring rod, and the lower positioning block automatically approaches the upper positioning block through a spring arranged outside the spring rod.

[0010] Optionally, the lower edge of the upper positioning block and the upper edge of the lower positioning block are both arranged as inclined surface structures, and a V-shaped positioning groove structure is formed by the inclined surface structures of the upper positioning block and the lower positioning block; a distance sensor is arranged between the two groups of lower positioning blocks pushed away from the upper positioning block.

[0011] Optionally, a precision positioning block is arranged on the inner wall of the channel module, the precision positioning block is connected and installed in the channel module through a small electric cylinder, and the precision positioning block is horizontally aligned with the upper positioning block and the lower positioning block.

[0012] Optionally, bearing seats are arranged outside both sides of the rotating shaft of the flexible paper feeding wheel, an elastic suspension element is fixedly arranged above the bearing seat, and the top of the elastic suspension element is hinged to the bottom of the upper channel module.

[0013] Optionally, the elastic suspension element is composed of two parallel spring steel sheets, and upper and lower connecting plates are connected and fixed; a limit block for limiting the spring steel sheet is fixedly arranged in the middle of the elastic suspension element.

[0014] Optionally, the bearing seats at both ends of the rotating shaft of the metal paper pressing wheel are fixedly arranged on the inner wall of the channel module through vertical spring rods.

[0015] Optionally, an arc groove structure is arranged on the outside of the flexible paper feeding wheel, and a diamond texture is arranged on the outer surface of the flexible paper feeding wheel; the main body of the metal paper pressing wheel is a double cam, and the convex arc of the metal paper pressing wheel is greater than the arc groove structure arc of the flexible paper feeding wheel.

[0016] Optionally, the processing method of the printing paper preparation production processing device includes the following steps: 1). In the normal position, when the paper enters the channel and contacts the upper positioning block and the lower positioning block, under the action of the spring, the movable block presses tightly against the edge of the paper, causing the paper to be embedded in the V-shaped positioning groove, achieving preliminary positioning. As the paper continues to move forward, through the continuous action of the upper positioning block and the lower positioning block, the lateral position of the paper is gradually corrected. When the paper reaches the last V-shaped positioning groove, the edge of the paper contacts the lower positioning block and pushes the upper positioning block away. If it is sensed that the lower positioning block will still displace, the small electric cylinder is activated to push the precision positioning block on one side of the paper out of position to compensate for the paper. 2). Conveying: When the paper enters the paper conveying wheel row composed of the flexible paper conveying wheel and the metal paper pressing wheel, the flexible paper conveying wheel automatically adjusts its vertical position under the action of the elastic suspension element, making the wheel surface fit the paper surface. The diamond texture on the surface of the flexible paper conveying wheel increases the friction with the paper and provides continuous driving force during the movement of the paper. When there are local deformations or wrinkles on the paper, the paper in the deformed area will bulge and contact the corresponding flexible paper conveying wheel. Since the flexible paper conveying wheel adopts an arc-shaped groove design, the bulging paper can be embedded in the groove and continue to move forward under the driving force of the flexible paper conveying wheel, avoiding the paper in the deformed area from being blocked or damaged. At the same time, the metal paper pressing wheel applies a uniform pressing force to the paper under the action of the spring. The metal paper pressing wheel and the flexible paper conveying wheel are arranged alternately. When the local deformation area of the paper passes through the metal paper pressing wheel, the double convex surface design of the metal paper pressing wheel can flatten the deformed area and prevent the generation and expansion of wrinkles. Since the contact area between the metal paper pressing wheel and the paper is large enough, it will not cause damage to the paper surface even during high-speed operation.

[0017] The beneficial effects are as follows: 1. Multiple groups of independently suspended flexible paper conveying wheel rows are adopted. Through elastic suspension and surface texture design, the problems of paper wrinkles, deformation, and damage during high-speed conveying are overcome. The paper conveying wheels can adaptively fit the paper surface, adapt to local deformation, and provide uniform driving force. At the same time, the alternately arranged metal paper pressing wheels apply a slight pressure to the paper, flatten the local deformation, and prevent the generation and expansion of wrinkles. Through flexible suspension and alternate arrangement, high-speed, stable, and damage-free paper conveying is achieved, greatly improving the conveying quality and efficiency.

[0018] 2. Through the upper positioning block, the lower positioning block, and the precision positioning block, the paper precision is improved. The preliminary positioning of the paper is achieved by spring pressing, and the left and right positions of the paper can be further adjusted by using the electric cylinder to drive the precision positioning block.

[0019] 3. The standardized module design, the quick connection mechanism, and the flexible adjustment mechanism overcome the problem of low equipment changeover efficiency. The channel modules are convenient for combination and splicing, and the handle is used for convenient control, installation, and disassembly. The space can be quickly adjusted according to the requirements of the paper size, which is convenient and fast. Brief Description of the Drawings

[0022] In order to make the objectives, solutions and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the specific embodiments of the present invention.

[0023] Embodiment 1: Please refer to the accompanying drawings in the specification, Figures 1 to 3 as shown: The present invention provides a printing paper preparation production processing device and its processing method, including: a channel module 1, the channel module 1 adopts an aluminum alloy profile frame structure, the frame is formed by connecting four profiles through corner codes, the cross-section of the profile is 40mm×40mm, the wall thickness is 2mm, positioning blocks for assembly are staggered on the outer edge of the channel module 1, and a handle is fixedly arranged in the middle of the outside of the channel module 1; notches are opened at the inlet and outlet of the channel formed by the channel module 1; two groups of guide plates 2 are rotatably arranged at the inlet of the channel module 1; a handwheel is arranged outside the rotating shaft of the guide plate 2, and the rotating shaft is locked by a setscrew; an L-shaped limit block 3 for limiting the guide plate 2 is fixedly arranged on the side of the inlet of the channel module 1; a flexible paper feeding wheel 7 and a metal paper pressing wheel 9 are rotatably arranged in the channel module 1, and the flexible paper feeding wheel 7 and the metal paper pressing wheel 9 are staggered.

[0024] Among them, an upper positioning block 4 is fixedly arranged on the inner side of the channel module 1, a lower positioning block 5 is slidably arranged on one side of the upper positioning block 4 in cooperation with a spring rod, and the lower positioning block 5 automatically approaches the upper positioning block 4 through the spring arranged outside the spring rod.

[0025] Among them, the lower edge of the upper positioning block 4 and the upper edge of the lower positioning block 5 are both set as inclined surface structures, and a V-shaped positioning groove structure is formed by the inclined surface structures of the upper positioning block 4 and the lower positioning block 5; a distance sensor is arranged between the two groups of lower positioning blocks 5 pushed away from the upper positioning block 4.

[0026] Among them, precise positioning blocks 6 are arranged on the inner wall of the channel module 1. The precise positioning blocks 6 are connected and installed in the channel module 1 through small electric cylinders, and the precise positioning blocks 6 are horizontally aligned with the upper positioning block 4 and the lower positioning block 5.

[0027] Among them, bearing seats are arranged outside both sides of the rotating shaft of the flexible paper feeding wheel 7. An elastic suspension element 8 is fixedly arranged above the bearing seat. The top of the elastic suspension element 8 is hinged to the bottom of the upper channel module 1.

[0028] Among them, the elastic suspension element 8 is composed of two parallel spring steel sheets, and connecting plates are arranged up and down to connect and fix them; a limiting block for limiting the spring steel sheets is fixedly arranged in the middle of the elastic suspension element 8.

[0029] Among them, the bearing seats at both ends of the rotating shaft of the metal paper pressing wheel 9 are fixedly arranged on the inner wall of the channel module 1 through vertical spring rods.

[0030] Among them, an arc groove structure is arranged outside the flexible paper feeding wheel 7, and diamond-shaped textures are arranged on the outer surface of the flexible paper feeding wheel 7; the main body of the metal paper pressing wheel 9 is a double cam, and the convex surface radian of the metal paper pressing wheel 9 is greater than the radian of the arc groove structure of the flexible paper feeding wheel 7.

[0031] Multiple groups of independently suspended flexible paper feeding wheels 7 are adopted. These flexible paper feeding wheels 7 are made of flexible materials, with anti-slip textures on the surface, and are independently suspended through elastic elements, and can float freely in the vertical direction; when the paper passes through, the flexible paper feeding wheels 7 can automatically adjust the height according to the surface morphology of the paper, adapt to local wrinkles and deformations, and at the same time apply a uniform driving force; between adjacent two groups of flexible paper feeding wheels 7, the designer also arranges several groups of small-diameter metal paper pressing wheels 9, which are arranged staggered with the flexible paper feeding wheels 7, apply a slight pressing force to the paper, and while providing a driving force, flatten the local deformation of the paper and prevent the generation and expansion of wrinkles; through the spring, the pressing force between the flexible paper feeding wheels 7 and the metal paper pressing wheels 9 can be adjusted, so that it can automatically adjust when the paper thickness or surface roughness changes, ensuring both a reliable driving force and not damaging the paper.

[0032] A multi-stage paper positioning mechanism is designed. This mechanism is composed of several groups of positioning blocks arranged along the paper conveying direction. Each group of positioning blocks includes an upper positioning block 4 and a lower positioning block 5. The lower positioning block 5 maintains an initial distance from the upper positioning block 4 through a spring. When the paper is conveyed to the positioning block, the lower positioning block 5 adheres to the edge of the paper under the action of the spring to achieve preliminary positioning; At the end of the paper conveying direction, the designer has set a precision positioning block 6, which forms a mechanical linkage with the previous positioning block through a wedge mechanism. When the previous positioning block presses against the edge of the paper, its displacement is transmitted to the precision positioning block 6 through the wedge, pushing the precision positioning block 6 to move laterally until it precisely fits the edge of the paper. This multi-stage positioning mechanical structure amplifies the positioning accuracy and ensures high-precision positioning of the paper in the lateral direction; The designer has designed the conveying channel as several detachable channel modules 1. Different channel modules 1 correspond to different paper size ranges. When changing the paper, only the corresponding channel module 1 needs to be quickly replaced, without major adjustments to the entire machine, thus shortening the changeover time; Inside the channel, the designer has also designed manually adjustable guide plates 2 for guiding the paper through, and these guide plates 2 can be quickly adjusted to adapt to the new paper size.

[0033] Embodiment 2: Based on Embodiment 1, as Figure 1 shown, the channel modules are connected together by bolts and positioning pins to form a complete conveying channel. The size and connection method of the modules are carefully designed to ensure the stability and detachable nature of the channel.

[0034] The specific usage method and function of this embodiment: In the present invention, when the paper enters the channel and contacts the upper positioning block 4 and the lower positioning block 5, under the action of the spring, the movable block presses against the edge of the paper, causing the paper to be embedded in the V-shaped positioning groove to achieve preliminary positioning. As the paper continuously advances, through the continuous action of the upper positioning block 4 and the lower positioning block 5, the lateral position of the paper is gradually corrected; when the paper reaches the last V-shaped positioning groove, the edge of the paper contacts the lower positioning block 5 and pushes the upper positioning block 4 away. If it is sensed that the lower positioning block 5 will still displace, then the small electric cylinder is activated to push the precision positioning block 6 on one side of the paper out to compensate for the paper. When the paper enters the paper feed wheel row formed by the flexible paper feed wheel 7 and the metal paper pressing wheel 9, the flexible paper feed wheel 7 automatically adjusts its vertical position under the action of the elastic suspension element 8, so that the wheel surface fits the paper surface. The diamond texture on the surface of the flexible paper feed wheel 7 increases the friction with the paper and provides continuous driving force during the movement of the paper. When encountering local deformation or wrinkles of the paper, the paper in the deformed area will bulge and contact the corresponding flexible paper feed wheel 7. Since the flexible paper feed wheel 7 adopts an arc-shaped groove design, the bulging paper can be embedded in the groove and continue to move forward under the driving force of the flexible paper feed wheel 7, avoiding the paper in the deformed area from being blocked or damaged. The metal paper pressing wheel 9 applies a uniform pressing force to the paper under the action of the spring. The metal paper pressing wheel 9 and the flexible paper feed wheel 7 are arranged alternately. When the local deformation area of the paper passes through the metal paper pressing wheel 9, the double convex surface design of the metal paper pressing wheel 9 can flatten the deformed area and prevent the generation and expansion of wrinkles. Since the contact area between the metal paper pressing wheel 9 and the paper is large enough, it will not cause damage to the paper surface even during high-speed operation.
