Description

Technical Field

[0001] This application relates to the field of composite material production technology, and in particular to a winding device for producing paper-plastic composite materials. Background Technology

[0002] Tackifier-specific packaging materials, also known as paper-plastic composites, are packaging bag materials refined from paper and plastic through a specific composite process. This material not only inherits the excellent printability of paper but also incorporates the superior waterproof, moisture-proof, and oxidation-resistant properties of plastic, thus finding widespread application in the packaging industry. Especially in the packaging of tackifiers, paper-plastic composites have become an ideal packaging choice due to their unique properties. Its production process involves multiple stages, including pretreatment of the paper and plastic film, adhesive coating and lamination, hot pressing and shaping, and final winding and cutting. Among these processes, winding, as the final stage of the production line, plays a crucial role in orderly and tightly winding the continuously produced paper-plastic composite materials into a cylindrical shape.

[0003] In related technologies, traditional winding devices generally suffer from the problem of difficulty in controlling winding tension. Whether it is too high or too low, it may have an adverse effect on the material. When the tension is too high, the material is prone to stretching and deformation, or even breakage, which seriously affects the integrity and quality of the product. On the other hand, if the tension is too low, the material may accumulate loosely on the roll, resulting in an uneven surface. This not only affects the appearance, but also brings many inconveniences in subsequent processing and use, reducing overall production efficiency and user experience. Therefore, it needs to be improved. Utility Model Content

[0004] To address the problem of difficulty in controlling winding tension in traditional winding devices, this application provides a winding device for the production of paper-plastic composite materials.

[0005] The winding device for producing paper-plastic composite materials provided in this application adopts the following technical solution:

[0006] A winding device for producing paper-plastic composite materials includes a frame. A winding roller is rotatably mounted on one side of the frame. A first guide roller and a second guide roller are sequentially arranged on the frame. A translation roller is mounted on the side of the first guide roller near the second guide roller. The translation roller is arranged parallel to the first guide roller. Two tension mechanisms are symmetrically arranged at both ends of the translation roller. Each tension mechanism includes a translation cylinder, a translation hinge rod, and a translation slider. The translation cylinder is connected to the bottom of the frame. The translation hinge rod is hinged to the frame, with one end hinged to the output end of the translation cylinder and the other end hinged to the translation slider. The translation slider is slidably connected to the frame. Both ends of the translation roller are rotatably connected to the two translation sliders, respectively.

[0007] Traditional winding devices generally suffer from difficulty in controlling winding tension. Whether the tension is too high or too low, it can adversely affect the material. When the tension is too high, the material is prone to stretching and deformation, or even breakage, seriously affecting the integrity and quality of the product. On the other hand, when the tension is too low, the material may accumulate loosely on the roll, resulting in an uneven surface. This not only affects the appearance but also causes many inconveniences in subsequent processing and use, reducing overall production efficiency and user experience. By adopting the above technical solution, including the frame, winding roller, first guide roller, and second guide roller, all are rotatably mounted on the frame. A translation roller is installed on one side of the first guide roller. The translation roller is translated by a tension mechanism, which includes a translation cylinder, a translation hinge rod, and a translation slider.

[0008] When winding paper-plastic composite materials, the paper-plastic composite material to be wound is placed at the starting position of the production line, and the winding device is started, so that the winding roller, the first guide roller, the second guide roller and the translation roller start to operate. The paper-plastic composite material is fed into the device from the starting position of the production line. First, it is guided by the first guide roller to ensure that the material moves forward along the predetermined path. When the material passes the translation roller, the tension mechanism starts to play its role. The translation cylinder drives the translation slider and the translation roller to move on the frame through the translation hinge rod, thereby adjusting the tension of the material before winding. After the tension is adjusted, the material continues to move forward, passes through the second guide roller, and finally reaches the winding roller. The winding roller starts to rotate and tightly and orderly winds the material.

[0009] By incorporating translation rollers and tension mechanisms, the translation rollers can be precisely adjusted in position as needed, effectively controlling the tension of the paper-plastic composite material before winding. This precise tension control prevents the material from stretching, deforming, or breaking due to excessive tension, and also prevents problems such as material accumulation, looseness, and uneven surface caused by insufficient tension. This not only improves the product's aesthetics but also ensures smooth subsequent processing and use, thereby enhancing overall production efficiency and user experience. Furthermore, this winding device is highly flexible and can be widely applied in the production of various paper-plastic composite materials, improving the equipment's versatility.

[0010] Optionally, the frame is provided with translation grooves for two translation sliders to slide, and the translation grooves are horizontally provided on the side wall of the frame.

[0011] By adopting the above technical solution, the translation chute is horizontally opened on the side wall of the frame; through the setting of the translation chute, the translation chute provides a stable and precise sliding track for the translation slider, ensuring the stability and accuracy of the translation roller when adjusting the tension.

[0012] Optionally, a buffer assembly is provided between any of the translation hinge rods and the corresponding translation slider. The buffer assembly includes a buffer spring and a buffer block. The buffer block is hinged to the end of the translation hinge rod away from the translation cylinder. One end of the buffer spring is connected to the buffer block, and the other end of the buffer spring is connected to the translation slider.

[0013] By adopting the above technical solution, the buffer assembly is installed between the translation hinge rod and the translation slider. The buffer assembly includes a buffer spring and a buffer block. By setting the buffer assembly, the impact and vibration generated by the translation hinge rod when driving the translation slider and translation roller to translate can be absorbed and mitigated. This helps to make the movement of the translation roller smoother, extend its service life, reduce material tension fluctuations caused by impact and vibration, and improve winding quality.

[0014] Optionally, the second guide roller is provided with a lifting mechanism, which includes a lifting roller, a lifting cylinder, and a lifting seat. The lifting cylinder is arranged on the frame and faces the height direction of the frame. The lifting seat is connected to the output end of the lifting cylinder. Both the second guide roller and the lifting roller are rotatably connected to the lifting seat, and the lifting roller is located directly above the second guide roller.

[0015] By adopting the above technical solution, the lifting mechanism is installed on the frame. The lifting mechanism includes a lifting roller, a lifting cylinder, and a lifting seat. After the paper-plastic composite material passes the translation roller and completes the tension adjustment, the material continues to move along the production line and prepares to enter the area of ​​the second guide roller. At this time, the lifting cylinder starts to move after receiving the control signal. Its output end pushes the lifting seat to move up and down along the height direction of the frame, adjusting the second guide roller to a height that matches the material's travel path, effectively guiding the material again. At the same time, the lifting roller is located directly above the second guide roller. It can slightly press or assist in guiding the material when needed to ensure that the material does not deviate or wrinkle when passing through the second guide roller.

[0016] By setting up a lifting mechanism, the height of the second guide roller can be precisely adjusted to match the material's travel path, ensuring that the material maintains a smooth and accurate travel path when passing through the second guide roller. This avoids material deviation or wrinkling caused by inaccurate guidance, further improving the winding quality. At the same time, it is applicable to paper-plastic composite materials of different materials, thicknesses, and widths, improving the equipment's versatility and flexibility.

[0017] Optionally, a guide sleeve is provided on the frame, and a guide rod is provided on the top of the lifting seat, the guide rod being slidably connected inside the guide sleeve.

[0018] By adopting the above technical solution, the guide sleeve is installed on the frame, and the lifting seat slides inside the guide sleeve through the guide rod. The setting of the guide rod and guide sleeve ensures the stability and accuracy of the lifting seat during movement, avoids deviation or jamming, and enhances the stability of the lifting mechanism.

[0019] Optionally, fine-tuning components are symmetrically arranged on both sides of the lifting roller. Each fine-tuning component includes a fine-tuning block and a fine-tuning bolt. One end of the fine-tuning bolt is connected to the fine-tuning block, and the other end of the fine-tuning bolt is connected to the lifting seat. The two fine-tuning blocks in the two fine-tuning components are respectively arranged at both ends of the lifting roller, and the lifting roller is rotatably connected to the two fine-tuning blocks.

[0020] By adopting the above technical solution, the fine-tuning components are installed on both sides of the lifting roller. Each fine-tuning component includes a fine-tuning block and a fine-tuning bolt. When it is necessary to fine-tune the lifting roller, use an appropriate tool to loosen the fixing nut on the fine-tuning bolt of the lifting seat. Gently push or pull the fine-tuning block according to the required direction and range. After adjusting to the required position, use a tool to tighten the fixing nut on the fine-tuning bolt again.

[0021] By setting the fine-tuning component, the position of the lifting roller can be adjusted precisely to ensure that the lifting roller can accurately meet production needs. This helps to optimize the travel path, pressure distribution and guiding effect of paper-plastic composite materials, thereby improving the winding quality.

[0022] Optionally, a support for mounting a take-up roller is provided on one side of the frame, the take-up roller is rotatably connected to the support, and a take-up motor for driving the take-up roller to rotate is provided on the support.

[0023] By adopting the above technical solution, the support is installed on the frame, and the support uses the winding motor to drive the winding roller to rotate. Through the setting of the support and the winding motor, the support provides a stable support for the winding roller, ensuring the stability of the winding roller during rotation. At the same time, the winding motor, as a power source, can continuously and stably provide driving force, enabling the winding roller to maintain a constant speed and tension, further ensuring the stability and uniformity of winding.

[0024] Optionally, the bottom of the support is provided with an adjustment mechanism for adjusting the position of the take-up roller. The adjustment mechanism includes an adjustment slide rail, an adjustment slider, and an adjustment cylinder. The adjustment slide rail is arranged along the width direction of the frame. The adjustment slider is slidably connected to the adjustment slide rail. The support is connected to the top of the adjustment slider. The adjustment cylinder is arranged on the frame. The output end of the adjustment cylinder is connected to the support.

[0025] By adopting the above technical solution, the adjustment mechanism is installed at the bottom of the support. The adjustment mechanism includes an adjustment slide rail, an adjustment slider, and an adjustment cylinder. When adjusting the position of the take-up roller for different specifications of products, the machine is stopped and the power is turned off. According to the production needs or the specifications of the paper-plastic composite material, the specific position of the take-up roller that needs to be adjusted is determined. The adjustment cylinder is started. The cylinder is extended and retracted according to the required adjustment direction (such as left and right movement). The support will drive the adjustment slider to slide on the adjustment slide rail. After confirming that the position of the take-up roller is correct, the adjustment cylinder stops working to ensure that the take-up roller is in the appropriate position.

[0026] By adjusting the mechanism, the position of the take-up roller can be quickly adjusted according to production needs or the specifications of paper-plastic composite materials. This helps to adapt to products of different sizes, thicknesses, or types, improving the equipment's versatility and adaptability. At the same time, it eliminates the need for complex disassembly and reassembly, shortening adjustment time and improving production efficiency.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] By incorporating translation rollers and tension mechanisms, the translation rollers can be precisely adjusted in position as needed, thereby effectively controlling the tension of the paper-plastic composite material before winding. This precise tension control prevents the material from stretching, deforming, or breaking due to excessive tension, and also prevents the problems of material accumulation, looseness, and uneven surface caused by insufficient tension. This not only improves the aesthetics of the product but also ensures smooth subsequent processing and use, thereby improving overall production efficiency and user experience.

[0047] The implementation principle of a winding device for paper-plastic composite material production according to an embodiment of this application is as follows: When winding the paper-plastic composite material, the paper-plastic composite material to be wound is placed at the starting position of the production line. The winding device is started, causing components such as the winding roller 2, the first guide roller 3, the second guide roller 4, and the translation roller 5 to start operating. The paper-plastic composite material is fed into the device from the starting position of the production line. First, it is guided by the first guide roller 3 to ensure that the material moves along a predetermined path. When the material passes the translation roller 5, the tension mechanism 6 starts to function. The translation cylinder 601 drives the translation slider 603 and the translation roller 5 to move on the frame 1 through the translation hinge rod 602, thereby adjusting the tension of the material before winding. The adjusted material continues to move forward, preparing to enter the area of ​​the second guide roller 4. At this time, the lifting cylinder 802 starts to move after receiving the control signal. Its output end pushes the lifting seat 803 to move up and down along the height direction of the frame 1, adjusting the second guide roller 4 to a height that matches the material's travel path, effectively guiding the material again. At the same time, the lifting roller 801 is located directly above the second guide roller 4. It can slightly press or assist in guiding the material when needed, ensuring that the material does not deviate or wrinkle when passing through the second guide roller 4. After passing through the second guide roller 4, it finally reaches the take-up roller 2. The take-up motor 13 works, and the take-up roller 2 starts to rotate, tightly and orderly winding the material.

[0048] By incorporating components such as the translation roller 5 and the tension mechanism 6, the translation roller 5 can be precisely adjusted in position as needed, thereby effectively controlling the tension of the paper-plastic composite material before winding. This precise tension control prevents the material from stretching, deforming, or breaking due to excessive tension, and also prevents problems such as material accumulation, looseness, and uneven surface caused by insufficient tension. This not only improves the aesthetics of the product but also ensures smooth subsequent processing and use, thereby improving overall production efficiency and user experience. At the same time, this winding device is highly flexible and can be widely applied in the production of various paper-plastic composite materials, improving the equipment's versatility.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
