[0002] At present, in some laminating production lines or film production lines with loopers, after the upper roll material is unwound, the tail of the material will be in a tension-free state before the subsequent main speed machine or winder, which will cause the tension-free material to become loose or deflected when passing through the equipment in each process section, which will make the material easy to scratch the equipment, causing damage to the equipment or material, resulting in economic losses. Some large production lines will install tension rollers and other equipment here to put them into linkage control of the entire line, but this is costly and complex to control, and is temporarily less used in laminating production lines or some film production lines. In order to avoid this situation and provide the necessary tension, a set of simple but effective devices is designed. Through manual control of the device, when necessary, the pressure roller is pressed down and braking force is provided to the support roller, so that the material of the pressure roller and the support roller obtains corresponding braking force, thereby providing necessary tension between the material and the subsequent main speed roller or winder.

[0039] Reference Figures 1 to 5A material tensioning device on a continuous production line comprises a support 1 and a support roller 2, a pressure roller 3, a brake 4, and a first driving mechanism 5 mounted on the support 1. The pressure roller 3 is located above the support roller 2 and parallel to the support roller 2. The first driving mechanism 5 is used to drive the pressure roller 3 to approach or move away from the support roller 2 in the vertical direction. The support roller 2 is rotatably mounted on the support 1. The brake 4 is used to limit the rotation of the support roller 2. The pressure roller 3 is rotatably fixedly connected to the support 1. When the pressure roller 3 moves downward, it is used to press the material to be tensioned between the pressure roller 3 and the support roller 2. Plate and strip materials are input into the continuous production line through an unwinding machine 9 for processing. Before the end of a roll of material is input into the production line, the first driving mechanism 5 can be automatically controlled by a program or manually controlled to drive the pressure roller 3 to move downward. The pressure roller 3 can be pressed down in advance before the roll is completely unwound. The pressure roller 3 presses the part of the plate and strip material moved to the position of the pressure roller 3 down to the support roller 2. After the pressing is in place, the brake 4 can be started by automatic program control or manual control to brake the support roller 2, which can ensure the tension required for material production, and has a simple structure and is easy to control. Through automatic or manual control of the material tensioning device on the continuous production line of this solution, the plate is tensioned to ensure that the plate will not scrape against other equipment except the roller surface due to relaxation, thereby ensuring the normal quality of the plate.

[0040] Specifically, the brake 4 includes a second driving mechanism 43, a brake wheel 41 and a clamping piece 42. One end of the support roller 2 is fixedly connected to the brake wheel 41 and rotates synchronously with the brake wheel 41. The second driving mechanism 43 is installed on the bracket 1. The second driving mechanism 43 is used to drive the clamping piece 42 to press down the brake wheel 41 to limit the rotation of the brake wheel 41.

[0041] Specifically, the clamping member 42 is a belt, and the second driving mechanism 43 is provided with a first piston rod. When the second driving mechanism 43 is started, the first piston rod extends or contracts; the belt passes over the brake wheel 41 from above the brake wheel 41 and the two ends are detachably fixed downward to the bracket 1 and the first piston rod respectively. When the first piston rod contracts downward, the belt presses the brake wheel 41 downward to brake the brake wheel 41.

[0042] Specifically, the bracket 1 includes a base 11 and two parallel and spaced first and second mounting plates 12 and 13 mounted on the upper end of the base 11.

The two ends of the pressure roller 3 are rotatably inserted into the first guide groove 121 and the second guide groove 131 and are slidably connected to the first mounting plate 12 and the second mounting plate 13. When the pressure roller 3 slides synchronously along the first guide groove 121 and the second guide groove 131, it approaches or moves away from the support roller 2. The two ends of the support roller 2 are rotatably fixedly connected to the first mounting plate 12 and the second mounting plate 13.

[0043] Specifically, the material tensioning device on the continuous production line of the present scheme also includes two first bearing seats 6, and the two ends of the pressure roller 3 are rotatably connected to the two first bearing seats 6, and the two first bearing seats 6 can be slidably embedded in the first guide groove 121 and the second guide groove 131 respectively.

[0044] Specifically, the materials on the continuous production line of the present scheme also include two second bearing seats 7. The first mounting plate 12 is also provided with through holes corresponding to each of the second bearing seats 7. Each of the second bearing seats 7 is respectively embedded in the through holes and is detachably fixedly connected to the bracket 1. The two ends of the support roller 2 are respectively rotatably connected to the two second bearing seats 7.

[0045] Specifically, the first driving mechanism 5 includes two first cylinders 51, and the two first cylinders 51 are respectively mounted on the upper ends of the first mounting plate 12 and the second mounting plate 13, and the lower end of each first cylinder 51 is provided with a second piston rod, and the lower end of each second piston rod is respectively detachably fixedly connected to a first bearing seat 6, and when the two second piston rods are synchronously extended or shortened, the pressure roller 3 approaches or moves away from the support roller 2.

[0046] Specifically, the second driving mechanism 43 is a second cylinder, and the second cylinder may preferably be a double earring support type cylinder.

[0047] Specifically, the material on the continuous production line of this solution also includes a fixing rod 14, the two ends of which are fixedly connected to the first mounting plate 12 and the second mounting plate 13 respectively. The setting of the fixing rod 14 enables the first mounting plate 12 and the second mounting plate 13 to remain in a stable state.

[0048] Specifically, the material on the continuous production line of the present solution also includes mounting seats 15 corresponding to each of the first cylinders 51. Each of the first cylinders 51 is detachably mounted on each of the mounting seats 15 by bolts. The upper ends of the first guide grooves 121 and the second guide grooves 131 are both provided with openings. One of the mounting seats 15 is detachably fixed to the upper end of the first mounting plate 12 and blocks the upper openings of each of the first guide grooves 121. The upper openings of the first guide grooves 121 are also the upper openings of the first mounting plate 12. The other mounting seat 15 is detachably fixed to the second mounting plate 13 and blocks the upper openings of the second guide grooves 131. The upper openings of the second guide grooves 131 are also the upper openings of the second mounting plate 13. The provision of the openings here facilitates the installation and disassembly of the first bearing seat 6.

[0049] In the normal production process of the plate and strip production line, the motor 92 of the unwinder 9 is in the power generation state, providing a backward reverse torque to the steel coil 8, so that the plate and strip are in a taut state from the entrance section to the next tension mechanism, but when the steel coil 8 or the plate and strip are separated from the mandrel 91 of the unwinder 9 after the unwinding, the plate and strip will be in a relaxed state. Therefore, before the unwinder 9 of the plate and strip production line is about to release the coil, the start or stop of the electric valve of the pressure roller 3 can be automatically controlled by the program or manually controlled to press the cylinder of the pressure roller 3 before the coil is released, and the pressure roller 3 presses the plate and strip material to the support roller 2. After pressing in place, the brake 4 can be started by automatic program control or manual control to control the contraction of the double earring support type cylinder piston rod, so that the belt and the brake wheel 41 are in friction contact, so that the support roller 2 produces a braking effect. Among them, the surface of the support roller 2 is made of PU material, which can be combined with the pneumatic pressure reducing valve that can be adjusted at any time to adjust the size of the braking torque, and the plate and strip can be tensioned according to the actual tightness of the plate. By automatically or manually controlling the material tensioning device on the continuous production line of this solution, the plate is tensioned to ensure that the plate will not be scratched by other equipment except the roller surface due to relaxation, thereby ensuring the normal quality of the plate.

[0050] The material tensioning device on the continuous production line of this scheme can be used in steel strip production lines or continuous production lines of cloth, paper and film. The material tensioning device on the continuous production line of this scheme is installed in front of the entrance loop. When the production line entrance needs to be sewn or spliced, after the last roll of coiled material is released, the tensioning force is generated when the tail of the belt is in a state of no tension. It can be used for the maximum tension of the whole line to be 200-600kgf, the thickness of the plate and strip material is 0.028-0.6mm, on the basis of the pressure roller 3 providing downward pressure on the support roller 2, the pneumatic system will generate a suitable braking force between the support roller 2 and the pressure roller 3 under the action of the brake cylinder and the brake belt, and the material between the pressure roller 3 and the support roller 2 will have a suitable braking resistance, so that the material on the production line The subsequent main speed roller, winder and brake device form the necessary tension. The driving mode is a pneumatic cylinder, and the operation mode is manual or online automatic. It has a power mechanism for independent or linkage use. It is simple to control, light in weight, easy to operate, occupies a small area, and is economical and applicable. It is suitable for tensioning materials before the entrance looper of a continuous production line.

[0051] On a continuous production line, when the strip material is about to be separated from the mandrel of the unwinder, the strip material will be in a relaxed state. The material tensioning device on the continuous production line of this solution is used for tensioning. First, the first driving mechanism is controlled to drive the pressure roller to move downward to a suitable position to press the strip material down to the support roller. Then the brake is activated to limit the rotation of the support roller, and a brake is generated between the support roller and the pressure roller, which exerts a certain braking resistance on the strip material between the pressure roller and the support roller. At this time, the strip material is in a tensioned state.
