The second limiting plate 22 is slidably sleeved on the periphery of the release roller 5; when working, the existing positioning and transmission device is unable to accurately position the reel 6 on the release roller 5 and the winding roller 8 during the transmission of the composite film 7. The error of the relative position of the two reels 6 is large, resulting in poor accuracy in positioning the composite film 7. By placing the reel 6 of the composite film 7 on the release roller 5, and then sleeved on the release roller 5, the second limiting plate 22 is clamped on the second sliding plate 17 on the second limiting plate 22, and then the screw 20 is screwed into the screw hole of the second sliding plate 17 and the second fixing rod 19, and the nut 21 is screwed into the screw 20, thereby achieving the fixation of the second sliding plate 17 and the second fixing rod 19. Fixed installation, at this time the composite film 7 roll is located between the first limit plate 16 and the second limit plate 22, turning the knob 12 to drive the first screw rod 11 to rotate, the first screw rod 11 drives the two sliders 13 thereon to move synchronously relative to each other, the two sliders 13 drive the first sliding plate 14 and the second sliding plate 17 to move synchronously relative to each other, the first sliding plate 14 and the second sliding plate 17 drive the first fixed rod 15 and the second fixed rod 19 to move synchronously relative to each other, the first fixed rod 15 and the second fixed rod 19 drive the first limit plate 16 and the second limit plate 22 to move synchronously relative to each other, so that the first limit plate 16 and the second limit plate 22 are in contact with the side wall of the roll 6 of the composite film 7, thereby realizing the horizontal position limitation of the roll 6 on the release roller 5;

[0020] Similarly, the roll 6 on the winding roller 8 is limited in the horizontal direction, and the two rolls 6 are respectively limited at the center of the release roller 5 and the winding roller 8.

[0021] See also Figure 5 As shown, a mounting plate 23 is installed on the base 1, and a lifting groove 24 is provided on the mounting plate 23. A stepping motor 25 is installed on the mounting plate 23 through the machine base. The stepping motor 25 is connected to the control panel 2 through an internal circuit. A second screw rod 26 is installed on the output shaft of the stepping motor 25. The second screw rod 26 is rotatably installed on the inner wall of the lifting groove 24. A lifting block 27 is assembled in the lifting groove 24, and a mounting block 28 is mounted on the lifting block 27. The mounting block 28 has a moving groove 29, and a moving block 30 is assembled in the moving groove 29. A tensioning roller 31 is rotatably installed on the moving block 30, a first electrode sheet 32 ​​is installed on the bottom side of the moving block 30, and a second electrode sheet 33 is installed on the inner wall of the moving groove 29. An indicator light 34 is installed on the side wall of the mounting plate 23, and the indicator light 34 is connected to the control panel 2 through an internal circuit. The control panel 2 is connected, the indicator light 34 is connected to the first electrode sheet 32 ​​and the second electrode sheet 33 through the internal circuit, and two groups of support plates 35 are installed on the base 1, and guide rollers 36 are rotatably installed on the support plates 35; when working, the existing positioning and transmission device cannot conveniently adjust the tension of the composite film 7 during the transmission of the composite film 7, resulting in poor convenience in adjusting the tension of the composite film 7. The loosening component and the winding component operate simultaneously, and the control panel 2 controls the two first motors 4 to operate, driving the loosening roller 5 and the winding roller 8 to rotate synchronously. The loosening roller 5 loosens the composite film 7 thereon, and then the composite film 7 passes around the two guide rollers 36 and the tensioning roller 31, and finally the winding roller 8 winds up the composite film 7, thereby realizing the transmission of the composite film 7;

[0022] During this process, the tension adjustment component operates, and the tension roller 31 moves vertically downward under the action of its own gravity, driving the moving block 30 thereon to move vertically downward, and the moving block 30 drives the first electrode sheet 32 ​​thereon to move vertically downward, so that the first electrode sheet 32 ​​contacts the second electrode sheet 33. At this time, the internal circuit of the indicator light 34 is connected, and the indicator light 34 sends an electrical signal to the control panel 2. After receiving the electrical signal, the control panel 2 controls the stepper motor 25 to operate, driving the second screw rod 26 to rotate, and the second screw rod 26 drives the lifting block 27 thereon to move vertically downward, and the lifting block 27 drives the mounting block 28 to move vertically downward, and the mounting block 28 drives the moving block 30 thereon to move vertically downward, and the moving block 30 drives the tension roller 31 thereon to move vertically downward until the tension roller 3 is tensioned. 1 contacts the composite film 7 and continuously presses the composite film 7 downward, so that the composite film 7 is in a tensioned state. When the composite film 7 is in a tensioned state, the composite film 7 will block the tensioning roller 31, and the tensioning roller 31 will not continue to move downward, but the mounting block 28 will continue to move downward, so that the first electrode sheet 32 ​​and the second electrode sheet 33 are quickly separated, and the electrical signal of the indicator light 34 disappears. At this time, the control panel 2 controls the stepping motor 25 to stop operating, so that the mounting block 28 stops moving downward, thereby realizing the adjustment of the tension of the composite film 7. When the composite film 7 becomes loose again, the above steps are repeated, and the tensioning roller 31 adjusts the tension of the composite film 7 again. This structure can autonomously adjust the tension of the composite film 7, which is conducive to improving the convenience of adjusting the tension of the composite film 7.

[0023] Working principle: In the process of transmitting the composite film 7, the existing positioning and transmission device cannot accurately position the reel 6 on the release roller 5 and the winding roller 8. The error in the relative position of the two reels 6 is large, resulting in poor accuracy in positioning the composite film 7. By placing the reel 6 of the composite film 7 on the release roller 5, and then putting the second limiting plate 22 on the release roller 5, the second fixing rod 19 on the second limiting plate 22 is clamped on the second sliding plate 17, and then the screw 20 is screwed into the screw hole of the second sliding plate 17 and the second fixing rod 19, and the nut 21 is screwed into the screw 20, the second sliding plate 17 and the second fixed rod 19 are fixedly installed. At this time, the composite film 7 roll is located between the first limit plate 16 and the second limit plate 22. The knob 12 is turned to drive the first screw rod 11 to rotate. The first screw rod 11 drives the two sliders 13 thereon to move synchronously relative to each other. The two sliders 13 drive the first sliding plate 14 and the second sliding plate 17 to move synchronously relative to each other. The first sliding plate 14 and the second sliding plate 17 drive the first fixed rod 15 and the second fixed rod 19 to move synchronously relative to each other. The first fixed rod 15 and the second fixed rod 19 drive the first limit plate 16 and the second limiting plate 22 move relative to each other synchronously, so that the first limiting plate 16 and the second limiting plate 22 are in contact with the side wall of the roll 6 of the composite film 7, thereby realizing the horizontal limitation of the roll 6 on the release roller 5; similarly, the roll 6 on the winding roller 8 is limited in the horizontal direction, and the two rolls 6 are respectively limited at the center of the release roller 5 and the winding roller 8. At this time, the release roller 5 and the roll 6 on the winding roller 8 are relative, realizing the precise positioning of the release roller 5 and the roll 6 on the winding roller 8, avoiding a large error in the relative position of the two rolls 6, which is beneficial to improving the composite film 7 Positioning accuracy; the existing positioning and transmission device cannot conveniently adjust the tension of the composite film 7 during the transmission of the composite film 7, resulting in poor convenience in adjusting the tension of the composite film 7. The release component and the winding component operate simultaneously, and the control panel 2 controls the two first motors 4 to operate, driving the release roller 5 and the winding roller 8 to rotate synchronously. The release roller 5 releases the composite film 7 thereon, and then the composite film 7 passes around the two guide rollers 36 and the tensioning roller 31, and is finally wound up by the winding roller 8, thereby realizing the transmission of the composite film 7.During this process, the tension adjustment component operates, and the tension roller 31 moves vertically downward under the action of its own gravity, driving the moving block 30 thereon to move vertically downward, and the moving block 30 drives the first electrode sheet 32 ​​thereon to move vertically downward, so that the first electrode sheet 32 ​​contacts the second electrode sheet 33. At this time, the internal circuit of the indicator light 34 is connected, and the indicator light 34 sends an electrical signal to the control panel 2. After receiving the electrical signal, the control panel 2 controls the stepper motor 25 to operate, driving the second screw rod 26 to rotate, and the second screw rod 26 drives the lifting block 27 thereon to move vertically downward, and the lifting block 27 drives the mounting block 28 to move vertically downward, and the mounting block 28 drives the moving block 30 thereon to move vertically downward, and the moving block 30 drives the tension roller 31 thereon to move vertically downward until the tension roller 3 is tensioned. 1 contacts the composite film 7 and continuously presses the composite film 7 downward, causing the composite film 7 to be in a tensioned state. When the composite film 7 is in a tensioned state, the composite film 7 blocks the tensioning roller 31, and the tensioning roller 31 does not continue to move downward. However, the mounting block 28 continues to move downward, causing the first electrode sheet 32 ​​and the second electrode sheet 33 to quickly separate. The electrical signal from the indicator light 34 disappears. At this time, the control panel 2 controls the stepper motor 25 to stop operating, causing the mounting block 28 to stop moving downward, thereby adjusting the tension of the composite film 7. When the composite film 7 becomes loose again, the above steps are repeated, and the tensioning roller 31 adjusts the tension of the composite film 7 again. This structure can autonomously adjust the tension of the composite film 7, which is conducive to improving the convenience of adjusting the tension of the composite film 7.
