Sensor 4 is used to detect the position of the web 100 and transmit the position signal to the control unit. In this embodiment, sensor 4 is an ultrasonic sensor. The control unit is used to control the drive unit 2 to swing the deflection correction roller 1 to a corresponding angle based on the feedback signal from sensor 4.

[0020] The drive unit 2 is used to drive the correcting roller 1 to oscillate. It has a power output shaft 21, and the bracket 3 is fixedly mounted on the power output shaft 21 of the drive unit 2. In this embodiment, the drive unit 2 includes a motor 22 and a reducer 23. The motor 22 is a servo motor 22, and its rotating shaft is connected to the reducer 23. The rotating shaft of the reducer 23 (i.e., the power output shaft 21 of the drive unit 2) is connected to the bracket 3. The correcting roller 1 is rotatably mounted on a roller shaft 11. One end of the roller shaft 11 is fixedly mounted on the bracket 3, and the roller shaft 11 is perpendicular to the power output shaft 21 of the drive unit 2. The motor 22 drives the bracket 3 to rotate via the reducer 23, thereby causing the correcting roller 1 to oscillate with the bracket 3.

[0021] In this embodiment, the bracket 3 is L-shaped and includes a connecting plate 31 and a mounting plate 32. The connecting plate 31 is vertically connected to the mounting plate 32. The connecting plate 31 is vertically mounted on one end of the power output shaft 21 of the drive unit 2, and one end of the roller shaft 11 is vertically mounted on the mounting plate 32. The connecting plate 31 includes two clamping members 311 and a locking member 312. Each clamping member 311 has an arc-shaped clamping portion (not shown in the figure) in the middle. The clamping portions of the two clamping members 311 are wrapped around the end of the power output shaft 21 of the drive unit 2. The locking member 312 is a bolt that locks and connects one end of the two clamping members 311 so that the clamping members 311 are fixed to the power output shaft 21 of the drive unit 2.

[0022] Bearings 13 are mounted on each end of the roller shaft 11, and the correcting roller 1 is mounted on both bearings 13. A tensioning sleeve 12 is mounted on the free end of the roller shaft 11, located outside the adjacent bearings 13. A collar (not shown) is also mounted on the roller shaft 11, sandwiched between the two bearings 13. The correcting roller 1 is mounted around the collar.

[0023] Please also read Figure 2 , is a preferred embodiment of the material strip transmission system in the present invention, and the material strip transmission system includes a support plate 200, a reel 300, a plurality of rollers 400 and the above-mentioned material strip correction mechanism. The support plate 200 is arranged vertically, and the reel 300 is used to wind the material strip 100, and the material strip 100 is wound around each roller 400 in sequence during operation. The reel 300, the plurality of rollers 400 and the drive unit 2 of the correction mechanism are all mounted on the support plate 200, and the correction roller 1 is located parallel between two of the rollers 400 arranged one above the other. The sensor 4 is mounted on the support plate 200 and is located upstream of the correction roller 1 in the transmission direction of the material strip 100. In this embodiment, the reducer 23 of the drive unit 2 is fixedly mounted on a mounting plate 5, and the drive unit 2 is fixedly mounted on the support plate 200 through the mounting plate 5.

[0024] When the above-described web conveyor system is operating, sensor 4 performs real-time detection of the position of web 100 entering roller 400, detects the edge of web 100, determines whether web 100 is deflected and the extent of the deflection, and outputs this information to the control unit, which calculates whether deflection correction is required and the amount of correction required. When web 100 reaches deflection correction roller 1, the control unit controls drive unit 2 to deflect deflection correction roller 1 by an angle corresponding to the deflection of web 100, thereby correcting the position of web 100. Figure 2 In the embodiment shown, when the position of the material strip 100 deflects toward the support plate 200 (e.g. Figure 2 As shown by the arrow A in the middle), the control unit controls the deviation correction roller 1 to swing clockwise (as shown by the arrow A in the middle). Figure 2 On the contrary, when the position of the material belt 100 deviates in the direction away from the support plate 200, the control unit controls the deviation correction roller 1 to swing in the counterclockwise direction.

[0025] The material strip correction mechanism and material strip transmission system of the present invention are connected to the drive unit 2 and the correction roller 1 through the bracket 3. The roller shaft 11 of the correction roller 1 is perpendicular to the power output shaft 21 of the drive unit 2. The control unit can control the swing angle of the correction roller 1 driven by the drive unit 2 through the bracket 3 through the signal feedback from the sensor 4 to achieve correction. Its structure is relatively simple and the volume is small.
