Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a full-automatic paper mounting machine with stable conveying. Background Art

[0002] In the field of paper processing, the laminating process is a key production link, widely used in industries such as packaging and printing. As modern industrial production continues to increase its requirements for production efficiency and product quality, the importance of laminating machines in the paper processing process has become increasingly prominent.

[0003] Traditional paper laminating operations often rely on manual labor or semi-automated equipment. Manual laminating is not only inefficient, but also difficult to ensure consistent laminating quality due to human error. This can easily lead to problems such as uneven lamination of the top and bottom papers and uneven glue application. With the development of automation technology, paper laminating machines emerged, but early paper laminating machines gradually exposed some problems in practical use.

[0004] Many existing paper laminating machines are described in Chinese Patent Publication No. CN118744599A. It is pointed out that in terms of the layout of the face paper conveying and the bottom paper conveying, most paper laminating machines adopt an upper and lower layered method. Under this structure, there are many unstable factors in the existing face paper conveying. Specifically, when the face paper moves from the starting end to the subsequent process, because the face paper conveying is located in the upper layer, it is conveyed horizontally and obliquely. There is a lack of effective tension adjustment measures on this face paper conveying path. When the paper thickness changes or the machine operating speed fluctuates, the paper tension cannot be stably controlled. For example, when the face paper is thin and the machine is accelerated, the paper is prone to wrinkles and accumulation due to insufficient tension; when the face paper is thick and the machine is decelerated, the paper may tear due to excessive tension.

[0005] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-6 In an embodiment of the utility model, a fully automatic paper laminating machine with stable conveying comprises a body 1, on which a face paper conveying device 2, a bottom paper conveying device 3, a gluing and laminating device 4, and a finished product pressing and conveying device 5 are provided. The left side of the gluing and laminating device 4 is connected to the face paper conveying device 2 and the bottom paper conveying device 3. The face paper conveying device 2 and the bottom paper conveying device 3 are arranged in layers up and down. The right side of the gluing and laminating device 4 is connected to the finished product pressing and conveying device 5.

[0032] A transmission frame 34 is provided on the surface paper conveying device 2, and the transmission frame 34 includes a horizontal conveying platform 6 and an inclined conveying platform 7 connected to each other. The end of the horizontal conveying platform 6 away from the inclined conveying platform 7 is the surface paper conveying end 8, and the end of the inclined conveying platform 7 away from the horizontal conveying platform 6 is the surface paper output end 9 connected to the gluing and laminating device 4 and the bottom paper conveying device 3, wherein the horizontal conveying platform 6 is provided with an elastic tensioning mechanism 25, and the inclined conveying platform 7 is provided with a paper suction mechanism 10.

[0033] In the technical solution of this utility model, the overall structure design of this fully automatic paper mounting machine is aimed at achieving an efficient and stable paper mounting process. Specifically:

[0034] The machine body 1 serves as a basic frame, providing a stable installation platform and support structure for each functional device, ensuring the mechanical stability of the entire paper laminating machine during operation. The face paper conveying device 2, the bottom paper conveying device 3, the gluing and laminating device 4, and the finished product pressing and conveying device 5 are arranged in an orderly manner on the machine body 1 to form a continuous production line. The face paper conveying device 2 and the bottom paper conveying device 3 are arranged in layers. This layout method comprehensively considers the respective conveying paths of the face paper and the bottom paper in the paper laminating process, avoids mutual interference, and facilitates the subsequent laminating operation requirements. The gluing and laminating device 4 is located after the two and is the core link of the entire paper laminating process. Here, the face paper and the bottom paper are accurately laminated, the glue is evenly distributed, and the two are firmly combined. The finished product pressing and conveying device 5 further compacts and conveys the laminated paper to ensure that the laminating quality meets high standards. At the same time, it prepares for subsequent packaging, printing and other processes, and ensures that the paper will not have problems such as delamination or deformation during subsequent processing;

[0035] The conveying frame 34 is the key path for facial paper transportation. It is connected by a horizontal conveying platform 6 and an inclined conveying platform 7. The horizontal conveying platform 6 is the starting part for facial paper to enter the conveying system. Its design purpose is to provide a stable initial conveying environment for facial paper. It ensures that the facial paper can start to move at a uniform speed and a stable posture when entering the conveying device. The length and width of the horizontal conveying platform 6 are designed according to the common facial paper sizes and conveying speed requirements to ensure that the facial paper can be fully unfolded and run smoothly at this stage; the inclined conveying platform 7 is the transition part connecting the horizontal conveying platform 6 and the gluing and laminating device 4. Its inclination angle is precisely calculated to take into account the facial paper to be able to slide smoothly under the action of gravity, and to avoid the facial paper sliding too fast and losing control due to an excessively large angle. The design of the inclined conveying platform 7 allows the facial paper to gradually change height during transportation, accurately reach the specified position of the gluing and laminating device 4, and achieve precise docking with the base paper. At the same time, the connection between the inclined conveying platform 7 and the horizontal conveying platform 6 adopts a smooth transition design to reduce vibration and deviation of the facial paper during the transition process.

[0036] The elastic tensioning mechanism 25 provided on the horizontal conveying platform 6 is intended to address the problem of unstable paper tension during conveyance caused by variations in paper thickness and fluctuations in machine speed. This mechanism utilizes the properties of elastic elements (such as springs, elastic rubber, etc.) to automatically expand and contract as paper tension changes, thereby maintaining the paper tension within an appropriate range. For example, when the machine accelerates, causing the paper tension to increase, the elastic element will appropriately expand to alleviate the increase in tension. When the paper becomes thinner and the tension decreases, the elastic element will contract, increasing the paper tension and preventing problems such as wrinkles, accumulation, or tearing.

[0037] The paper suction mechanism 10 on the inclined conveying platform 7 is designed to overcome gravity and unstable factors in the conveying process when the facial paper is in the inclined conveying stage. By generating suction, the paper suction mechanism 10 tightly adsorbs the facial paper on the conveying platform, ensuring the position accuracy of the facial paper during the inclined conveying process and preventing it from deflecting, thereby ensuring that the facial paper can accurately enter the gluing and laminating device 4 and be laminarized with the base paper; specifically, the paper suction mechanism 10 on the inclined conveying platform 7 utilizes the negative pressure adsorption principle, which may include a plurality of suction nozzles or suction channels distributed on the surface of the inclined conveying platform 7, these suction nozzles or suction channels are connected to a vacuum pump or a negative pressure generating device, when the facial paper is conveyed on the inclined conveying platform 7, The vacuum pump is started, forming a negative pressure environment at the suction nozzle or the suction channel; due to the existence of the inclination angle, the facial paper will be affected by the component force of gravity along the inclination direction, which is prone to sliding and deflection. The suction force of the paper suction mechanism 10 can effectively overcome this gravity component force, ensuring the position accuracy of the facial paper during the inclined transportation process. At the same time, the suction force of the paper suction mechanism 10 can be adjusted according to factors such as the material, weight and transportation speed of the facial paper. For example, for lighter facial paper, the suction force can be appropriately reduced to avoid damage to the facial paper; for heavier facial paper or facial paper with a smoother surface, the suction force can be increased to ensure the adsorption effect, so that the facial paper can accurately enter the gluing and laminating device 4 and be laminated with the base paper.

[0038] In summary, this fully automatic paper laminating machine realizes a fully automated continuous production process from the conveying of face paper and base paper, gluing and laminating to the pressing and conveying of finished products, which reduces the time waste in the manual operation link and greatly improves the production quantity per unit time. The various devices work closely together to form an efficient production line, so that the paper laminating process can be carried out quickly and stably. The elastic tensioning mechanism 25 of the horizontal conveying and the paper suction mechanism 10 of the inclined conveying work together to create ideal conditions for the conveying of face paper. The elastic tensioning mechanism 25 accurately controls the tension of the face paper during horizontal conveying, so that it can In the face of changes in paper thickness, material or fluctuations in machine operating speed, it can maintain stability, avoid tearing, wrinkling or accumulation, improve paper adaptability, conveying accuracy and extend equipment life. The paper suction mechanism 10 plays a key role in the inclined conveying stage. The adsorption force it generates overcomes the sliding and offset problems of the surface paper caused by the tilt, ensures the accurate position of the surface paper and stable speed, and improves the fitting accuracy with the base paper. At the same time, its suction force can be adjusted according to the characteristics of the paper. The two complement each other to ensure the smooth and stable process of conveying the surface paper from horizontal to inclined, greatly improving the paper mounting quality and production efficiency.

[0039] In the embodiment of the present utility model, the horizontal conveying platform 6 is provided with two first limiting plates 11 arranged opposite to each other, and a first track 12 corresponding to the surface paper conveying end 8 is formed between the two first limiting plates 11;

[0040] The inclined conveying platform 7 is provided with two second limiting plates 13 that are opposite to each other. A second track 14 corresponding to the paper output end 9 is formed between the two second limiting plates 13 , and the second track 14 is connected to the first track 12 .

[0041] The first track 12 and the second track 14 formed by the first limiting plate 11 and the second limiting plate 13 enable the lateral position of the facial paper to be precisely controlled during the entire conveying process, from the horizontal stage to the inclined stage. This ensures that the facial paper can accurately reach the gluing and laminating device 4 for lamination with the base paper, avoiding lamination errors caused by the deviation of the facial paper in the width direction, thereby improving the quality and accuracy of paper lamination. For example, when the facial paper is conveyed at high speed, the first limiting plate 11 and the second limiting plate 13 can effectively prevent the facial paper from deviating from the correct path due to airflow or slight vibration, thereby ensuring the accuracy of each paper lamination operation.

[0042] In an embodiment of the present utility model, the elastic tensioning mechanism 25 includes a mounting block 15, a connecting block 16, a tensioning spring 17, an adjusting screw 18 and a pressure wheel 19. The mounting block 15 is arranged on the inner side of the first limiting plate 11. The mounting block 15 includes a fixed part 20 and a movable part 21. The inner side of the movable part 21 is provided with a pressure wheel 19 corresponding to the first rail 12. The connecting block 16 is L-shaped, and its vertical end 22 is fixed on the outer side of the first limiting plate 11. Its horizontal end 23 is located above the movable part 21 and is movably connected to the adjusting screw 18. The lower end of the adjusting screw 18 passes through the horizontal end 23 of the connecting block 16 and is connected to the tensioning spring 17. The end of the tensioning spring 17 away from the adjusting screw 18 is connected to the movable part 21.

[0043] The design of the elastic tensioning mechanism 25 is to effectively control the tension of the facial paper on the horizontal conveying platform 6. Through the coordinated action of various components, the tensioning force can be flexibly adjusted according to the actual situation of the facial paper. Specifically: the mounting block 15 is located on the inner side of the first limiting plate 11, utilizing the space defined by the first limiting plate 11, and also working together with the first limiting plate 11 to stabilize the conveying of the facial paper; the mounting block 15 is divided into a fixed part 20 and a movable part 21. This design allows the movable part 21 to move within a certain range, thereby realizing the adjustment of the tensioning force. The pressure wheel 19 on the inner side of the movable part 21 is in direct contact with the facial paper and is a key component for applying the tensioning force; the connecting block 16 It is L-shaped, and its vertical end 22 is fixed to the outside of the first limit plate 11, ensuring the stability of the entire mechanism and the firmness of the installation. The horizontal end 23 is located above the movable part 21 and is movably connected to the adjusting screw 18, providing a suitable installation position and movement space for the adjusting screw 18; the connection between the adjusting screw 18, the tensioning spring 17 and the movable part 21 constitutes an adjustable elastic system. The adjusting screw 18 serves as a manual control component for adjusting the tensioning force. By rotating it, the compression degree of the tensioning spring 17 can be changed, thereby changing the elastic force acting on the movable part 21, and finally achieving the adjustment of the pressure between the pressure wheel 19 and the surface paper, that is, the control of the surface paper force.

[0044] In the embodiment of the present utility model, a limiting groove 24 is provided along the upper end of the movable portion 21, and a connecting block is provided at the inner bottom of the limiting groove 24, and the end of the tensioning spring 17 away from the adjusting screw 18 is engaged with the connecting block;

[0045] The adjusting screw 18 includes a nut head 26, a threaded portion 27 and a non-threaded portion 28 coaxially arranged in sequence, and the non-threaded portion 28 is located within the vertical projection range of the threaded portion 27, wherein the corresponding mating end of the tensioning spring 17 is sleeved on the non-threaded portion 28 and abuts against the threaded portion 27.

[0046] The limiting groove 24 is provided along the upper end of the movable portion 21 to position and limit the connection of the lower end of the tensioning spring 17. A connecting block is provided at the inner bottom of the limiting groove 24 to make the connection between the tensioning spring 17 and the movable portion 21 more stable and reliable. This design prevents the spring from unnecessary lateral displacement or shaking on the movable portion 21 when subjected to compression or tension, ensuring that the elastic force of the spring can be accurately transmitted in a direction perpendicular to the movable portion 21, thereby stably acting on the pressure wheel 19 to achieve precise control of the force on the opposite paper.

[0047] The nut head 26 is located at the top of the adjusting screw 18. Its design purpose is to facilitate the operator to use tools (such as wrenches, etc.) to rotate the adjusting screw 18. The threaded portion 27 and the horizontal end 23 of the connecting block 16 are threadedly matched to realize the up and down movement of the adjusting screw 18 in the vertical direction. When the adjusting screw 18 is rotated, the threaded action between the threaded portion 27 and the connecting block 16 converts the rotational motion into linear motion. The non-threaded portion 28 is located within the vertical projection range of the threaded portion 27, and the corresponding mating end of the tensioning spring 17 is sleeved on the non-threaded portion 28 and The non-threaded portion 28 is offset against the threaded portion 27. This design has two important functions. First, during the up and down movement of the adjusting screw 18, the non-threaded portion 28 provides a stable guide and support structure for the spring, preventing the spring from twisting or deflecting when compressed or extended, and ensuring that the elastic force of the spring is evenly distributed along the axial direction. Second, by means of the spring and the threaded portion 27 offsetting each other, when the adjusting screw 18 rotates to make the threaded portion 27 rise or fall, the degree of compression of the spring can be directly changed, thereby accurately changing the size of the elastic force generated by the spring, thereby realizing sensitive adjustment of the force on the opposite paper.

[0048] In the embodiment of the present invention, the pressure wheel 19 is connected to the inner side of the movable portion 21 via a rotating shaft, and the outer surface of the pressure wheel 19 is provided with textures.

[0049] The pinch wheel 19 is connected to the inner side of the movable portion 21 via a rotating shaft. This connection method enables the pinch wheel 19 to rotate flexibly relative to the movable portion 21. During the tissue paper conveying process, the tissue paper is continuously moving, and the pinch wheel 19 needs to roll along with the movement of the tissue paper. The design of the rotating shaft meets this movement requirement. Through the rotating shaft, the pinch wheel 19 can convert the linear movement of the tissue paper into its own rotational movement, thereby reducing the sliding friction between the tissue paper and the pinch wheel 19, and reducing the friction loss to the tissue paper and the pinch wheel 19.

[0050] The texture on the outer surface of the pressure wheel 19 enhances the friction between it and the facial paper, which is crucial for accurately controlling the tension of the facial paper. During the facial paper conveying process, appropriate friction can ensure that the facial paper maintains stable tension under different operating speeds and working conditions. For example, when the machine starts, accelerates or decelerates, the friction provided by the texture can prevent the facial paper from becoming loose or overly tight due to inertia or speed changes. In addition, when the material or thickness of the facial paper changes, the texture can also ensure that the pressure wheel 19 always has sufficient grip to control the movement of the facial paper, thereby improving the quality and reliability of the facial paper conveying link in the entire paper mounting process.

[0051] In one implementation of an embodiment of the present invention, a long hole 29 is provided along the side of the fixing portion 20, and a threaded groove matching the long hole 29 is provided on the first limiting plate 11. The threaded groove and the long hole 29 are fixedly connected by a screw 30, wherein the position of the screw 30 in the long hole 29 is adjustable.

[0052] The long hole 29 is opened along the side of the fixing portion 20 and the matching threaded groove is provided on the first limiting plate 11 in order to realize the adjustable installation of the elastic tensioning mechanism 25 in the horizontal direction. The long hole 29 provides a certain moving space for the screw 30, so that the mounting block 15 (a part of the elastic tensioning mechanism 25) can be adjusted relative to the first limiting plate 11 within the length range of the long hole 29. This design takes into account the need to change the lateral position of the elastic tensioning mechanism 25 according to the width of the surface paper, the fine-tuning requirements of the conveying path or the differences in the characteristics of different batches of paper during the actual production process.

[0053] In an embodiment of the present invention, the second limiting plate 13 includes a horizontal portion 31 and a connected vertical plate 32, and the paper suction mechanism 10 includes a plurality of suction ports 33 arranged at intervals along the length direction of the horizontal portion 31 (as described above, the suction ports 33 are connected to a vacuum pump or a negative pressure generating device).

[0054] The main function of the vertical portion is to limit the lateral direction of the facial paper, that is, the vertical portion is perpendicular to the conveying direction and the inclined plane of the facial paper, and can directly block the lateral movement of the facial paper; the horizontal portion 31 serves as the installation basis for the suction port 33, and the suction port 33 is arranged along the length direction of the horizontal portion 31 in order to make full use of the width range of the facial paper during the inclined conveying process to achieve comprehensive adsorption of the facial paper.

[0055] In one embodiment, the first limit plate 11 and the second limit plate 13 are adjustable, and the first limit plate 11 and the second limit plate 13 can be adjusted by program-controlled related control components. In this control mode, a driving component such as a stepper motor or a servo motor can be installed at the first limit plate 11 / second limit plate 13 adjustment mechanism, and connected to the first limit plate 11 / second limit plate 13 through a transmission device such as a screw rod and a gear. At the same time, a position sensor such as a photoelectric sensor or a Hall sensor is set on the moving path of the first limit plate 11 / second limit plate 13, and a programmable logic controller (PLC) is used as the core control unit, in which a control logic program is written to cover manual and automatic adjustment modes; the adjusted position can also be fixed by adopting methods such as the combination of guide rails and sliders, card slots and blocks, and at the same time cooperating with fastening devices.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
