DETAILED DESCRIPTION
[0015] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.
[0016] See also Figure 1 to Figure 2The present embodiment discloses a wire pulling device for high-speed cigarette packaging equipment, including a frame 1, on which a core support 2, an unwinding roller 3 and a pulling mechanism are installed, the core support 2 is used to install a wire pulling drum 4, the unwinding roller 3 is located on one side of the core support 2, and the pulling mechanism includes a movable pulling roller group 5 and a fixed pulling roller group 6 respectively arranged on the left and right sides above the unwinding roller 3, the fixed pulling roller group 6 includes a fixed installation shaft fixed to the frame 1 and a plurality of fixed pulling rollers rotatably installed on the fixed installation shaft in sequence, the movable pulling roller group 5 includes a movable installation shaft and a plurality of movable pulling rollers rotatably installed on the movable installation shaft in sequence, the movable installation shaft is fixed to the upper end of a detection swing rod 7, the lower end of the detection swing rod 7 is rotatably installed on the frame 1 through a hinge shaft, and the detection swing rod 7 is automatically reset by a torsion spring on the hinge shaft. The number of the plurality of movable pulling rollers is equal to and corresponds to the number of the plurality of fixed pulling rollers, and the movable pulling rollers have the same shape as the corresponding fixed pulling rollers.
[0017] In this embodiment, three fixed traction rollers are sequentially rotatably mounted on the fixed installation shaft, and three movable traction rollers are sequentially rotatably mounted on the movable installation shaft. The outer diameters of the multiple fixed traction rollers on the fixed installation shaft gradually decrease from the inside to the outside, and the outer diameters of the multiple movable traction rollers on the movable installation shaft gradually decrease from the inside to the outside. The three fixed traction rollers are respectively the first fixed traction roller 10, the second fixed traction roller 11, and the third fixed traction roller 12 from the inside to the outside, and the three movable traction rollers are respectively the first movable traction roller 13, the second movable traction roller 14, and the third movable traction roller 15 from the inside to the outside.
[0018] Each movable traction roller and fixed traction roller are provided with limiting convex rings at both ends to prevent the pull wire 8 from slipping out. The area defined by the limiting convex rings at both ends of the movable traction roller or the fixed traction roller forms a conveying roller 9, and the width of the conveying roller 9 is greater than the width of a single pull wire 8.
[0019] During operation, the wire drawing reel 4 is first installed on the winding core support 2. After the wire drawing wire 8 is unwound from the wire drawing reel 4 into a single wire drawing wire 8, it first passes through the unwinding roller 3, and then passes through the first fixed traction roller 10, the first movable traction roller 13, the second fixed traction roller 11, the second movable traction roller 14, the third fixed traction roller 12 in sequence, and then is led out through the third movable traction roller 15, and the non-adhesive surface of the wire drawing wire 8 contacts each roller.
[0020] The wire pulling device 8 provided in the present embodiment designs the original single pulling roller into a plurality of pulling rollers arranged coaxially in sequence, and the wire 8 is wound and conveyed on the plurality of pulling rollers of the movable pulling roller group 5 and the fixed pulling roller group 6 in sequence, which effectively extends the overall pulling path of the wire 8, ensures the stable pulling and conveying of the wire 8, and prevents the wire 8 from falling off, getting entangled, and other problems during the pulling and conveying process; at the same time, the outer diameter of the traction rollers of each group of traction rollers gradually decreases from the inside to the outside, so that in the traction path of the wire 8, the diameter of the traction roller close to the wire pulling drum 4 on the winding core support 2 is larger, and the diameter of the traction roller away from the wire pulling drum 4 on the winding core support 2 gradually decreases, which further prevents the wire 8 from falling off, getting entangled, and other problems during the pulling and conveying process, and further ensures the stability of the traction and conveying process of the wire 8.
[0021] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
