DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0025] Example 1: See Figures 1 to 5 As shown, a conveying mechanism that is easy to adjust includes a frame 1 and a driving roller 2 rotatably mounted on the frame, an adjusting mechanism is also installed on the frame on the left side of the driving roller, and the adjusting mechanism includes an adjusting roller 3 and a bracket 4, the bottom of the bracket is rotatably mounted on the frame, and the two ends of the adjusting roller are rotatably mounted on the top of the bracket, the adjusting roller is arranged parallel to the driving roller, and the adjusting roller is arranged below the left side of the driving roller;

[0026] The bracket includes a connecting shaft 5 and two sets of side plates 6. The connecting shaft is arranged parallel to the adjusting roller and the driving roller. The two ends of the connecting shaft are rotatably connected to the frame. The bottoms of the two sets of side plates are respectively fixedly connected to the two ends of the connecting shaft. The two ends of the adjusting roller are rotatably connected to the tops of the two sets of side plates. The connecting shaft is arranged below the adjusting roller.

[0027] The front end of the frame is provided with a through hole, the front end of the coupling shaft passes through the through hole and is arranged outside the front end of the frame, and a grab bar 7 is vertically installed on the outer edge surface of the front end of the coupling shaft;

[0028] An external thread is provided on the outer edge surface of the front end of the coupling shaft, and a butterfly nut 8 is screwed on the external thread. The butterfly nut is arranged between the frame and the grab bar, and the rear side surface of the butterfly nut is against the front side surface of the frame.

[0029] In this embodiment, in actual use, the product is conveyed from left to right, wherein it will pass under the adjusting roller and then pass over the driving roller, and the right end is the processing equipment at the rear end, wherein, if the position is not accurate, under normal circumstances, the adjusting roller is set on the top, and when the position of the material strip needs to be adjusted, the unwinding end is first fixed, and then the operator first loosens the butterfly nut, and then the operator grabs the grab bar to drive the coupling to rotate counterclockwise, so that the adjusting roller rotates toward the lower left, so that the adjusting roller will pull the right end of the material strip to move to the left, wherein, how much the material strip moves to the left is determined by how much the adjusting roller rotates toward the lower left, so that rapid adjustment can be achieved. In this embodiment, a circular scale 9 can be set on the frame at the front end of the coupling, so that when the coupling rotates, the rotation angle can be accurately controlled, that is, the pulling distance of the material strip to the left can be controlled to ensure the accuracy and stability of the adjustment.

[0030] See also Figure 5 As shown, a mounting hole 10 is provided on the front outer edge of the coupling shaft, and one end of the grab bar is inserted into the mounting hole; a screw hole 11 is provided on the front end of the coupling shaft, and a locking bolt 12 is screwed into the screw hole, and the rear end of the locking bolt locks the grab bar and the coupling shaft. This makes it easy to connect and install the grab bar.

[0031] One end of the grab bar is provided with an annular groove 13, and the rear end of the locking bolt is inserted into the annular groove. The annular groove ensures that the locking bolt can be quickly inserted into the grab bar to limit the grab bar, and the grab bar can also rotate in the mounting hole without affecting the grab bar driving the shaft to rotate.

[0032] The rear end of the coupling shaft passes through the rear side of the frame and is arranged outside the rear side of the frame; the rear end of the coupling shaft is provided with an annular protrusion 14, and the front side of the annular protrusion abuts against the rear side of the frame. The setting of the annular protrusion can prevent the coupling shaft from moving forward, and the setting of the butterfly nut can prevent the coupling shaft from moving backward. When the butterfly nut is screwed and locked with the external thread of the coupling shaft, the coupling shaft will be pulled forward, so that the annular protrusion and the butterfly nut will lock the coupling shaft to prevent the coupling shaft from rotating, thereby ensuring that the adjusting roller plays a transmission role when in use.

[0033] See also Figure 1 , 2 As shown in FIG. 4 , a workbench 15 is provided on the frame on the left side of the adjusting roller, and a limiting mechanism is provided above the workbench.

[0034] The limiting mechanism includes a limiting plate 16 and a vertical cylinder 17, wherein the limiting plate is arranged directly above the workbench, and the vertical cylinder is arranged below the workbench. A vertical connecting rod 18 is respectively arranged on both sides of the bottom of the limiting plate, and the bottom of the vertical connecting rod passes through the workbench and is arranged directly below the workbench; a pulling plate 19 is also provided, wherein the pulling plate is arranged below the workbench, the pulling plate is arranged parallel to the limiting plate, the limiting plate and the pulling plate are arranged parallel to the adjusting roller, the two ends of the pulling plate are respectively connected to the bottoms of the two groups of vertical connecting rods, and the output shaft at the top of the vertical cylinder is connected to the middle part of the bottom surface of the pulling plate.

[0035] A rubber anti-slip layer 20 is provided on the bottom surface of the limiting plate.

[0036] When the vertical cylinder output shaft is extended, a gap is provided between the bottom surface of the rubber anti-slip layer and the top surface of the workbench; when the vertical cylinder output shaft is retracted, the bottom surface of the rubber anti-slip layer abuts against the top surface of the workbench.

[0037] In this embodiment, in order to ensure that when the adjusting roller pulls the right end of the material belt for adjustment, the material belt on the left side is prevented from being pulled to the right and affecting the adjustment accuracy of the material belt, a limit mechanism is provided. When adjustment is required, the vertical cylinder output shaft retracts, causing the limit plate to drop, and the rubber anti-skid layer is used to press the product. In this way, when the adjusting roller pulls the material belt to move to the left, the left side of the material belt is fixed and will not be pulled to the right, thereby ensuring the stability and accuracy of the material belt adjustment. When adjustment is not required, the vertical cylinder output shaft extends to release the limit plate from limiting the product.
