A tensioning and pressing mechanism and an anti-wrinkle mechanism are installed on the outer side of the support frame, which are respectively responsible for the tensioning and anti-wrinkle treatment of the material to ensure that the material The design of the tensioning and pressing mechanism is particularly critical to the stability of the material during the slitting process. It includes a base frame, an adjusting screw and a tensioning assembly. The base frame is fixed to the outside of the support frame, and its side is concave in shape for easy installation and adjustment. The adjusting screw is installed on the top of the base frame through a threaded connection, and its bottom passes through the base frame and is rotatably connected to the tensioning assembly. By rotating the adjusting screw, the tensioning assembly can be driven to slide on the inside of the base frame, thereby adjusting the tensioning pressure of the material. This design allows the device to flexibly adjust the tensioning force according to the characteristics and requirements of different materials to ensure the optimization of the slitting effect.

[0009] The top of the telescopic spring is rotatably connected to the bottom of the telescopic spring, and the tensioning roller is rotatably connected to the bottom of the telescopic spring.

[0010] Optionally, support rods are fixedly installed on both ends of the top of the tensioning frame, and the top of the support rods passes through the movable frame, the vertical rails and the base frame. Support rods are fixedly installed on both ends of the top of the tensioning frame. This design further enhances the stability and overall performance of the tensioning assembly. The top of the support rod not only passes through the movable frame, but also passes through the vertical rails and the base frame to form a stable supporting structure. This arrangement not only strengthens the connection between the tensioning frame and the movable frame, making the tensioning roller more stable and less likely to shake during movement, but also the design of the support rod passing through the vertical rails and the base frame also enhances the connection strength between the entire tensioning assembly and the base frame, making the entire device more stable and reliable during operation. In addition, the arrangement of the support rods also helps to improve the carrying capacity of the tensioning assembly, enabling it to cope with the challenges of greater tensioning force and material weight.

[0011] Optionally, an adjusting handle is fixedly installed on the top of the adjusting screw, and an armrest is fixedly installed on the outside of the adjusting handle at equal intervals. The top of the adjusting screw is specially designed with an adjusting handle. This humanized improvement greatly improves the operating convenience of the device. The design of the adjusting handle allows the operator to control the rotation of the adjusting screw more easily and intuitively, thereby achieving precise adjustment of the tensioning assembly. It is worth mentioning that armrests are also fixedly installed on the outside of the adjusting handle at equal intervals. This design not only further enhances the stability and grip comfort of the adjusting handle, but also enables the operator to control the adjusting handle more stably when operating for a long time or when greater force needs to be applied, thereby avoiding operating errors caused by hand slippage or fatigue.

[0012] Optionally, the slitting mechanism includes a concave frame, which is fixedly installed in the middle of the top of the support frame, and an electric push rod is fixedly installed in the middle of the top of the concave frame. The output end of the electric push rod passes through the concave frame and is fixedly installed with a cutting knife. The concave frame serves as a supporting structure of the entire slitting mechanism and is fixedly installed in the middle of the top of the support frame, thereby ensuring the stability and firmness of the slitting mechanism. An electric push rod is fixedly installed in the middle of the top of the concave frame. The electric push rod serves as a power source and realizes the up and down movement of the cutting knife through its telescopic movement. The output end of the electric push rod passes through the concave frame and is fixedly installed with a cutting knife. The cutting knife is a component that directly performs material cutting, and its sharpness and precision directly affect the cutting effect. When the electric push rod contracts, the cutting knife rises accordingly; when the electric push rod extends, the cutting knife descends to cut the material. This design enables the cutting process to be automatically controlled, thereby improving the cutting efficiency and precision.

[0013] Optionally, mounting plates are fixedly installed at the four corners of the base, mounting holes are opened at the outer ends of the mounting plates, and the mounting holes are set as countersunk holes. Mounting plates are fixedly installed at the four corners of the base. This design not only enhances the structural stability of the base, but also facilitates the installation of the entire slitting device. Mounting holes are opened at the outer ends of the mounting plates, and these mounting holes are set as countersunk holes. This design has multiple advantages. First, the design of the countersunk holes makes the mounting holes more beautiful, while avoiding the protrusion of the mounting screw heads, thereby preventing scratches and collisions during use. Secondly, the countersunk holes can accommodate the screw heads, so that the screws are more stable and not easy to loosen when fixing the mounting plates. Finally, the setting of the mounting holes makes the slitting device conveniently fixed to the desired position by screws or other fasteners. Whether it is fixed on a workbench or installed in a production line, quick and stable installation can be achieved.

[0014] Optionally, the anti-wrinkle mechanism includes side rails, which are fixedly installed on the front and rear ends of both sides of the support frame, and the side rails are arranged between the tensioning and pressing mechanism and the inner side of the slitting mechanism. A first motor is fixedly installed on the top of the side rail, and a screw rod is fixedly installed on the output end of the first motor through the side rail, and the screw rod is rotatably connected to the inside of the side rail, and the threads at both ends of the screw rod have opposite rotation directions, and both ends of the screw rod are threadedly connected to a driving assembly. The anti-wrinkle mechanism is mainly composed of side rails, a first motor, a screw rod and a driving assembly. The side rails are fixedly installed on the front and rear ends of both sides of the support frame and are located between the tensioning and pressing mechanism and the inner side of the slitting mechanism. Such a layout enables the anti-wrinkle mechanism to timely adjust the material during the material slitting process. For leveling, a first motor is fixedly installed on the top of the side rail, and the output end of the first motor passes through the side rail and is fixedly connected to the lead screw, which is rotatably connected to the inside of the side rail, and the threads at both ends thereof rotate in opposite directions. When the lead screw with a special design rotates, it can make the driving component threadedly connected thereto move toward or away from each other on the lead screw, and the driving component is threadedly connected to both ends of the lead screw. When the first motor drives the lead screw to rotate, the driving component will move along its axis driven by the lead screw, and the movement of the driving component further drives the movement of the anti-wrinkle roller connected thereto, and the anti-wrinkle roller then fits the surface of the material. As the anti-wrinkle roller moves, the material is effectively leveled during the slitting process, thereby avoiding the formation of wrinkles.

[0015] Optionally, the driving assembly includes a slider, which is slidably connected to the upper and lower ends of the inner side of the side rail, a connecting frame is fixedly installed on the outer side of the slider, the top view shape of the connecting frame is concave, and the side shape of the connecting frame is L-shaped. An anti-wrinkle roller is rotatably connected between the inner sides of the connecting frame, and a second motor is fixedly installed at one end of the connecting frame, and the output end of the second motor is fixedly connected to one end of the anti-wrinkle roller. The driving assembly mainly consists of a slider, a connecting frame, an anti-wrinkle roller and a second motor. The slider is slidably connected to the upper and lower ends of the inner side of the side rail. This design allows the slider to slide freely in the side rail, thereby driving the connecting frame and the anti-wrinkle roller to reciprocate. The top view shape of the connecting frame is concave, and the side The shape is L-shaped. This special design not only enhances the structural stability of the connecting frame, but also enables the anti-wrinkle roller to be stably installed on the inner side of the connecting frame. The anti-wrinkle roller is rotatably connected between the inner sides of the connecting frame. The anti-wrinkle roller is a key component for preventing material wrinkles. It adheres to the surface of the material and rotates with the material to achieve smooth processing of the material. In addition, a second motor is fixedly installed at one end of the connecting frame, and the output end of the second motor is fixedly connected to one end of the anti-wrinkle roller. When the second motor is started, it drives the anti-wrinkle roller to rotate, thereby achieving continuous smooth processing of the material. By accurately controlling the speed and direction of the second motor, the rotation speed and direction of the anti-wrinkle roller can be accurately adjusted to adapt to different materials and slitting requirements.

[0016] Optionally, anti-wrinkle scraping strips are fixedly connected to the outer surface of the anti-wrinkle roller at equal intervals, and the anti-wrinkle scraping strips are arranged as arc-shaped convex strips. During the slitting process, as the anti-wrinkle roller rotates, the anti-wrinkle scraping strips will also rotate accordingly and contact the surface of the material. Since the scraping strips are arranged as arc-shaped convex strips, they can slide along the surface of the material and flatten any wrinkles or uneven parts that may be produced. This continuous scraping action ensures that the material always remains flat during the slitting process, thereby improving the slitting quality and efficiency.

[0017] Optionally, the overall cross-sectional shape of the inner walls of the slider and the side rails are both cross-shaped, and the outer surface of the slider and the inner wall of the side rails are fixedly connected with wear-resistant gaskets. The overall cross-sectional shape of the inner walls of the slider and the side rails are both cross-shaped. This design not only enhances the stability and bearing capacity of the structure, but also makes the sliding of the slider in the side rails more stable and smooth. The cross-shaped structure can effectively disperse the force to prevent deformation or damage caused by excessive local force, thereby improving the durability and reliability of the entire anti-wrinkle mechanism. In addition, the outer surface of the slider and the inner wall of the side rails are also fixedly connected with wear-resistant gaskets. The wear-resistant gaskets are usually made of materials with excellent wear resistance, such as polymer materials or special alloys, which can effectively reduce the friction and wear between the slider and the side rails and extend the service life. At the same time, the wear-resistant gaskets can also play a role in buffering and vibration reduction, reduce the noise and vibration generated by the slider during sliding, and improve the running stability of the entire slitting device.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. By setting up a tensioning and pressing mechanism, the device can easily lay the material on the first guide roller and the second guide roller. By adjusting the rotation of the screw, the movable frame and the tensioning roller can be driven downward to achieve tensioning of the material, and the tensioning force can be adjusted by adjusting the screw. At the same time, the addition of the telescopic spring provides a buffering effect and enhances the cutting stability. The setting of the support rod further strengthens the telescopic spring and improves the overall tensioning capacity. Finally, by starting the electric push rod, the cutting knife moves downward to accurately cut the material. During the tensioning and cutting process, the taut state of the material effectively reduces wrinkles, improves the cutting quality and stability, and thus improves the overall performance of the device.

[0020] 2. By setting up the anti-wrinkle mechanism, this device can significantly improve the slitting quality. The first motor is started to drive the screw to rotate, so that the slider slides back and forth in the side rail, driving the anti-wrinkle rollers to displace each other and fit the material. At the same time, the second motor drives the anti-wrinkle rollers to rotate, the anti-wrinkle convex strips fit the surface of the material, the tensioning roller tightens the material horizontally, and the anti-wrinkle roller achieves longitudinal tension, ensuring that the material remains stable during the slitting process and avoiding wrinkles. This design keeps the material in a tight state in both the horizontal and vertical directions, effectively reducing wrinkles and greatly improving the slitting quality.

The top of the support rod 536 not only passes through the movable frame 532, but also passes through the vertical rail 531 and the base frame 51 to form a stable supporting structure. This arrangement not only strengthens the connection between the tension frame 534 and the movable frame 532, but also makes the tension roller 535 more stable and less likely to shake during movement. At the same time, the support rod The design of 536 passing through the vertical rail 531 and the base frame 51 also enhances the connection strength between the entire tensioning assembly 53 and the base frame 51, making the entire device more stable and reliable during operation.

The outer ends of the mounting plates 8 are opened with mounting holes 9, and these mounting holes 9 are set as countersunk holes. This design has multiple advantages. First, the design of the countersunk hole makes the mounting hole 9 more beautiful, and at the same time avoids the protrusion of the mounting screw head, thereby preventing scratches and collisions during use. Secondly, the countersunk hole can accommodate the screw The head makes the screws more stable when fixing the mounting plate 8 and is not easy to loosen. Finally, the setting of the mounting holes 9 makes it convenient to fix the slitting device at the desired position by screws or other fasteners. Whether it is fixed on a workbench or installed in a production line, it can achieve fast and stable installation. Therefore, by installing the mounting plate 8 with countersunk holes at the four corners of the base 1, not only the overall stability of the slitting device is improved, but also the installation process is greatly simplified and the work efficiency is improved. This design fully reflects the dual consideration of practicality and aesthetics, and shows the refinement and ingenuity of the design of the high-barrier composite material slitting device.

[0039] Please refer to Figure 4-Figure 5The driving assembly 74 includes a slider 741, which is slidably connected to the upper and lower ends of the inner side of the side rail 71. A connecting frame 742 is fixedly installed on the outer side of the slider 741. The top view of the connecting frame 742 is a concave shape, and the side view of the connecting frame 742 is an L-shaped setting. The inner side of the connecting frame 742 is rotatably connected to an anti-wrinkle roller 743. A second motor 744 is fixedly installed at one end of the connecting frame 742. The output end of the second motor 744 is fixedly connected to one end of the anti-wrinkle roller 743. The driving assembly 74 The main components include a slider 741, a connecting frame 742, an anti-wrinkle roller 743 and a second motor 744. The slider 741 is slidably connected to the upper and lower ends of the inner side of the side rail 71. This design allows the slider 741 to slide freely in the side rail 71, thereby driving the connecting frame 742 and the anti-wrinkle roller 743 to move back and forth. The top view of the connecting frame 742 is a concave shape, and the side view is an L-shaped setting. This special design not only enhances the structural stability of the connecting frame 742, but also allows the anti-wrinkle roller 743 to be stably The anti-wrinkle roller 743 is installed on the inner side of the connecting frame 742, and the anti-wrinkle roller 743 is rotatably connected between the inner sides of the connecting frame 742. The anti-wrinkle roller 743 is a key component for preventing material wrinkles. It achieves material flattening by fitting to the surface of the material and rotating with the material. In addition, a second motor 744 is fixedly installed at one end of the connecting frame 742, and the output end of the second motor 744 is fixedly connected to one end of the anti-wrinkle roller 743. When the second motor 744 is started, it drives the anti-wrinkle roller 743 to rotate, thereby achieving continuous flattening of the material. By accurately controlling the speed and direction of the second motor 744, the rotation speed and direction of the anti-wrinkle roller 743 can be accurately adjusted to meet different materials and slitting requirements. The design of the driving component 74 fully takes practicality and stability into consideration. The sliding of the slider 741 in the side rail 71 and the driving of the anti-wrinkle roller 743 by the second motor 744 achieves effective material flattening. This design not only improves the working efficiency of the slitting device, but also ensures the stability of the slitting quality.

[0040] Please refer to Figure 4-Figure 5The overall cross-sectional shape of the slider 741 and the inner wall of the side rail 71 are both in a cross shape, and the outer surface of the slider 741 and the inner wall of the side rail 71 are fixedly connected with a wear-resistant gasket. The overall cross-sectional shape of the slider 741 and the inner wall of the side rail 71 are both in a cross shape. This design not only enhances the stability and load-bearing capacity of the structure, but also makes the slider 741 slide more steadily and smoothly in the side rail 71. The cross-shaped structure can effectively disperse the force and prevent deformation or damage caused by excessive local force, thereby improving the durability and reliability of the entire anti-wrinkle mechanism 7. In addition, the outer surface of the slider 741 and the inner wall of the side rail 71 are also fixedly connected with a wear-resistant gasket, which is usually made of excellent wear resistance. The material is made of polymer material or special alloy, which can effectively reduce the friction and wear between the slider 741 and the side rail 71 and extend the service life. At the same time, the wear-resistant gasket can also play a role in buffering and vibration reduction, reduce the noise and vibration generated by the slider 741 during the sliding process, and improve the running stability of the whole slitting device. By adopting the design of the cross-shaped slider 741 and the side rail 71 and the fixed connection wear-resistant gasket, the anti-wrinkle mechanism 7 not only ensures the structural stability, but also improves the running stability and durability. This design not only helps to improve the overall performance of the slitting device, but also reduces the maintenance cost and replacement frequency, bringing more convenience and benefits to the composite material processing industry.

[0041] Please refer to Figure 4-Figure 5 The outer surface of the anti-wrinkle roller 743 is fixedly connected with anti-wrinkle scraping strips 745 at equal intervals. The anti-wrinkle scraping strips 745 are set as arc-shaped convex strips. During the slitting process, as the anti-wrinkle roller 743 rotates, the anti-wrinkle scraping strips 745 will also rotate and contact the surface of the material. Since the scraping strips are set as arc-shaped convex strips, they can slide along the surface of the material and scrape off any wrinkles or uneven parts that may be generated. This continuous scraping action ensures that the material always remains flat during the slitting process, thereby improving the slitting quality and efficiency. In addition, the anti-wrinkle scraping strips 745 The use of an equidistant fixed connection method ensures the uniform distribution of the scraper on the surface of the anti-wrinkle roller 743, making the anti-wrinkle effect more uniform and consistent. This design also takes into account the contact pressure between the scraper and the material. By reasonably setting the spacing and protrusion height of the scraper, a gentle and effective scraping treatment of the material surface is achieved, avoiding material damage caused by excessive pressure. The design of the anti-wrinkle scraper 745 on the outer surface of the anti-wrinkle roller 743 effectively improves the anti-wrinkle effect of the anti-wrinkle mechanism 7 through the shape of the arc-shaped protrusions and the equidistant fixed connection method.

[0042] The implementation principle of the slitting device of a high-barrier composite material in the embodiment of the present application is as follows: by setting a tensioning and pressing mechanism 5, the material is arranged on the outer surface of the first guide roller 3 and the second guide roller 4 during use of the device, and then the adjusting screw 52 is twisted and rotated. The movable frame 532 on the inner side of the side rail 71 can be driven to move downward by the rotation of the adjusting screw 52. The tensioning frame 534 and the tensioning roller 535 can be driven to move downward by the downward movement of the movable frame 532. At this time, the tensioning frame 534 and the tensioning roller 535 are in contact with the material arranged on the first guide roller 3 and the second guide roller 4. The tensioning pressure can be adjusted by twisting the downward movement degree of the adjusting screw 52, ​​and during the tensioning period, By setting up the telescopic spring 533, it can assist in buffering and improve the stability of the overall cutting process of the device. During the tensioning process, the support rod 536 is set to replicate the support and reinforcement of the telescopic spring 533, thereby improving its overall comprehensive tensioning ability and stability. At this time, by starting the electric push rod 62 on the top of the concave frame 61, the electric push rod 62 is used to push the cutting to move downward, and the material can be cut through the cutting. During the cutting process, the telescopic spring 533 cooperates with the squeezing of the tensioning roller 535 to make the material in a taut state, which can reduce the occurrence of wrinkles, improve the overall cutting stability, and improve the overall cutting quality of the device.

[0043] By setting up the anti-wrinkle mechanism 7, during use, the device can be operated by starting the first motor 72, and the first motor 72 is used to drive the screw rod 73 to rotate. The threads at both ends of the screw rod 73 rotate in opposite directions. When the screw rod 73 is located inside the side rail 71 and rotates, the screw rod 73 can be used to assist in driving the slider 741 to slide back and forth on the inner side of the side rail 71. The screw rod 73 drives the slider 741 to move, which can assist in driving the connecting frame 742 to drive the anti-wrinkle roller 743 to move relative to each other. The anti-wrinkle roller 743 fits the outer surface of the material. At this time, by starting the second motor 744 to operate , the second motor 744 can be used to assist in driving the anti-wrinkle roller 743 on the inner side of the connecting frame 742 to rotate. The rotation of the anti-wrinkle roller 743 can drive the anti-wrinkle convex strip to fit the outer surface of the material. The pressure applied by the tensioning roller 535 can cause the material to be horizontally tight, and the anti-wrinkle roller 743 drives the anti-wrinkle convex strip to fit the material to rotate, which can cause the material to be vertically tight, so that the material can have better stability during the slitting process, and the whole material can be in a horizontal and vertical tight state, which can avoid the occurrence of wrinkles to the greatest extent, and maximize the overall slitting quality of the device.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
