[0028] It is understandable that, referring to Figures 1 to 6The utility model discloses a film winding device, comprising a winding mechanism 100 and a deviation correction mechanism 200. The winding mechanism 100 comprises a frame 110, a winding roller 120, a first driving member 130 and two sets of tension adjustment components 140. The two sets of tension adjustment components 140 are respectively arranged on the left and right sides of the frame 110. The tension adjustment components 140 comprise a spring 141 and a slider 142. The slider 142 is slidably connected to the frame 110. The two ends of the spring 141 are respectively connected to the slider 142 and the frame 110. The spring 141 is used to drive the slider 142 to slide along the rear of the frame 110. The two ends of the winding roller 120 are respectively rotatably connected to the two sliders 142. The first driving member 130 is used to drive the slider 142 to slide along the rear of the frame 110. The two ends of the winding roller 120 are respectively rotatably connected to the two sliders 142. 30 is used to drive the winding roller 120 to rotate; the correcting mechanism 200 includes an adjusting roller 210, a turntable 220, a second driving member 230, a controller and two position sensors 240, the turntable 220 is rotatably connected to the frame 110, the second driving member 230 is used to drive the turntable 220 to rotate in a horizontal direction, the adjusting roller 210 is rotatably connected to the turntable 220, and the adjusting roller 210 is arranged along the radial direction of the turntable 220, the adjusting roller 210 is located in front of the winding roller 120, the two position sensors 240 are respectively arranged on the left and right sides of the frame 110, the position sensor 240 is used to sense the film, and the second driving member 230 and the position sensor 240 are both electrically connected to the controller.
[0029] The film is sequentially wound around the adjusting roller 210 and the winding roller 120, and the first driving member 130 drives the winding roller 120 to rotate so that the film is wound around the winding roller 120. When the film position is offset, the position sensor 240 on the offset side can sense the film and feed back a signal to the controller. The controller controls the second driving member 230 to drive the turntable 220 to rotate in the horizontal direction, and drives the adjusting roller 210 to deflect in the opposite direction of the film offset, thereby adjusting the horizontal distance between the winding roller 120 and the adjusting roller 210 to increase the tension of the film on the offset side and reduce the tension of the film on the other side, so that the film is adjusted to a preset position for winding, thereby realizing automatic deviation correction of the film, which can reduce the possibility of folding of the film, so as to improve the film winding. The roll quality, at the same time, when the film tension is greater than the preset value, the slider 142 slides along the front of the frame 110, driving the winding roller 120 to move in the horizontal direction close to the adjusting roller 210, and the spring 141 is compressed, which can reduce the horizontal distance between the winding roller 120 and the adjusting roller 210 to reduce the tension on the film during correction, thereby reducing the possibility of the film being pulled and deformed due to excessive local stress. When the film tension is less than the preset value, the spring 141 elastically recovers to drive the slider 142 to slide along the rear of the frame 110, which can increase the horizontal distance between the winding roller 120 and the adjusting roller 210 to increase the tension on the film. The elastic adjustment of the spring 141 can reduce the tension fluctuation of the film, thereby improving the film winding quality.
[0030] In addition, two sets of tension adjustment components 140 are respectively arranged on the left and right sides of the frame 110, and the position of the winding roller 120 is adjusted simultaneously by the two sets of tension adjustment components 140 to adjust the tension of the film, which can improve the stability of the tension adjustment.
[0031] It should be noted that when the film deviates to the left, the left position sensor 240 senses the film and feeds back a signal to the controller, and the turntable 220 drives the adjusting roller 210 to deflect to the right, thereby increasing the tension on the left side of the film and reducing the tension on the right side of the film, causing the film to deviate to the right side back to the preset position. When the film deviates to the right, the right position sensor 240 senses the film and feeds back a signal to the controller, and the turntable 220 drives the adjusting roller 210 to deflect to the left, thereby increasing the tension on the right side of the film and reducing the tension on the left side of the film, causing the film to deviate to the left side back to the preset position.
[0032] The controller is not shown in the drawings, and may be an industrial computer or a programmable logic controller, etc., which can control the second driving member 230 to perform corresponding actions.
[0033] The first driving member 130 and the second driving member 230 can both be servo motors or stepper motors, etc., and can drive the winding roller 120 and the turntable 220 to rotate.
[0034] It is understandable that, referring to Figure 3 and Figure 4 The frame 110 is provided with two slide grooves 111, which are arranged horizontally along the radial direction of the winding roller 120. The slide grooves 111 correspond to the sliders 142 one by one, and the sliders 142 are slidably connected to the slide grooves 111. By slidably connecting the sliders 142 to the slide grooves 111, and using the slide grooves 111 to guide the sliders 142 to slide horizontally along the radial direction of the winding roller 120, the position deviation of the winding roller 120 driven by the sliders 142 can be reduced, so as to improve the position stability of the winding roller 120, thereby improving the stability of the film tension adjustment.
[0035] Specifically, refer to Figure 3 The tension adjustment assembly 140 further includes a slide bar 143, which is connected to the frame 110 and is located in the slide slot 111. The slide bar 143 is arranged in parallel with the slide slot 111, the spring 141 is sleeved on the slide bar 143, and the slider 142 is slidably connected to the slide bar 143. Since the slide bar 143 is arranged in parallel with the slide slot 111, the spring 141 is sleeved on the slide bar 143, and the slider 142 is slidably connected to the slide bar 143, the stability of the elastic adjustment of the spring 141 can be improved by guiding the spring 141 to directional telescopic deformation by the slide bar 143, and the position deviation of the reel 120 driven by the slider 142 can be reduced by guiding the slider 142 to slide along the direction of the slide slot 111 by the slide bar 143, so as to improve the position stability of the reel 120, thereby improving the stability of the film tension adjustment.
[0036] It is understandable that, referring to Figures 2 to 4 The tension adjustment assembly 140 further includes a first stopper 144, which is connected to the frame 110 and is located on the side of the slider 142 away from the spring 141. The slider 142 can abut against the first stopper 144 to limit the sliding of the slider 142. The slider 142 abuts against the first stopper 144, which can limit the slider 142 from sliding backward, thereby limiting the moving distance of the slider 142 and the winding roller 120, reducing the risk of excessive film tension caused by excessive movement of the winding roller 120 when the slider 142 is driven to slide backward by the elastic force of the spring 141, thereby improving the stability and reliability of film tension adjustment.
[0037] Specifically, refer to Figure 3 and Figure 4 The first limit block 144 is slidably connected to the frame 110. The first limit block 144 can slide along the front-to-back direction of the frame 110. The frame 110 is provided with a plurality of first positioning holes 112. The plurality of first positioning holes 112 are evenly spaced along the front-to-back direction of the frame 110. The first limit block 144 is provided with a second positioning hole 145. The second positioning hole 145 is penetrated by a bolt 146. The bolt 146 is threadedly connected to one of the first positioning holes 112. The distance between the first limit block 144 and the slider 142 is adjusted by sliding the first limit block 144 along the front-to-back direction of the frame 110. When the first limit block 144 is adjusted to a preset position, the position of the first limit block 144 is fixed by tightening the bolt 146. The maximum travel distance of the slider 142 can be adjusted, thereby adjusting the maximum moving distance of the winding roller 120, further reducing the risk of excessive film tension caused by excessive movement of the winding roller 120, so as to improve the stability and reliability of film tension adjustment. In addition, since the frame 110 is provided with a plurality of first positioning holes 112 , which are evenly spaced apart along the front-rear direction of the frame 110 , the first limit block 144 can be positioned to different positions as required to improve the convenience of adjustment.
[0038] It is understandable that, referring to Figure 3 and Figure 5 The frame 110 is provided with a second limit block 250, and the turntable 220 is provided with an arc-shaped limit groove 221 along the circumferential direction. The second limit block 250 can abut against the wall of the arc-shaped limit groove 221 to limit the rotation of the turntable 220. The second limit block 250 abuts against the wall of the arc-shaped limit groove 221 to limit the rotation of the turntable 220, thereby limiting the deflection angle of the adjustment roller 210, which can reduce the risk of film winding or breaking due to excessive deflection angle of the adjustment roller 210, so as to improve the stability of film correction.
[0039] Specifically, refer to Figure 3 and Figure 5 , the two opposite side walls of the limit groove are respectively provided with detectors 222, the detectors 222 are used to sense the second limit block 250, the frame 110 is provided with an alarm 113, the alarm 113 and the detector 222 are both electrically connected to the controller. When the second limit block 250 abuts against the wall of the arc-shaped limit groove 221, that is, the deviation of the film has exceeded the adjustment range of the adjustment roller 210, the second limit block 250 is sensed by the detector 222 and a signal is fed back to the controller, and the controller controls the alarm 113 to sound an alarm to remind the operator to perform deviation correction in time, which can improve the film winding quality.
[0040] It is understandable that, referring to Figure 3 and Figure 6 The left and right sides of the frame 110 are respectively provided with mounting seats 260, and the mounting seats 260 are slidably connected with adjustment rods 270, and one adjustment rod 270 is connected to one position sensor 240, and the two adjustment rods 270 can slide closer to each other or away from each other. By moving the adjustment rods 270, the two adjustment rods 270 slide closer to each other or away from each other to adjust the distance between the two position sensors 240, which can adapt to the detection of films of different widths to correct deviation, thereby improving the applicability of the film winding device.
[0041] It should be noted that after the adjustment rod 270 is moved to the preset position, the position can be fixed by fasteners such as bolts and pins.
[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
