[0036] like Figures 1 to 5 As shown, the utility model provides a traction device for a die-cutting machine, including a traction frame 1, a guide cavity 2 for movably setting a guide slider 4 is symmetrically opened at the inner top of the traction frame 1, and an outer side wall of one side of the guide slider 4 is fixedly connected to one end of a return spring 3 fixedly connected to the inner side wall of the guide cavity 2, two connecting arms 5 are arranged between the bottom end of the guide slider 4 and the mounting frame 6, and both ends of the connecting arms 5 are respectively hinged to the bottom end of the guide slider 4 and the top end of the mounting frame 6 through hinge shafts, and the two connecting arms 5 are arranged in an "eight" shape. Through the arranged connecting arms 5, the guide slider 4 is driven to move in the guide cavity 2 by the potential energy of the return spring 3 during use, thereby driving the connecting arms 5 to move, and then the connecting arms 5 drive the mounting frame 6 to move downward.

[0037] Specifically, the top of the mounting frame 6 is fixedly connected to the bottom of the dustproof accordion cover 7, and the top of the dustproof accordion cover 7 is fixedly connected to the inner top of the traction frame 1. By setting the dustproof accordion cover 7, the connecting arm 5 and other components can be protected from dust during use.

[0038] A heat-conducting component is installed at the top of the interior of the mounting frame 6. The heat-conducting component includes a heating chamber 8, an electric heating rod 9 and a flexible layer 10. The heating chamber 8 is arranged at the top of the interior of the mounting frame 6, and the interior of the heating chamber 8 is fixedly connected to the electric heating rod 9.

The movable cavity is respectively opened inside the extension plate 12 and the traction frame 1, and the outer wall of the extension plate 12 is fixedly connected to the first motor 23. The output end of the first motor 23 passes through one side of the extension plate 12 and extends to the inside of the movable cavity and is fixed to the middle connecting rod of the movable wheel 17 through a coupling. The connecting rod is not shown in the figure. Through the setting of the first motor 23, the first motor 23 is energized and output during use, thereby driving the movable wheel 17 and the traction shaft 22 to rotate, thereby completing the traction operation.

[0043] It is worth noting that two movable sleeves 24 movably connected to the outer wall of the guide plate 25 are symmetrically fixedly connected to one side of the outer wall of the traction frame 1, and the guide plate 25 is fixedly connected between the two ends inside the base 26, and the outer walls of one side of the two movable sleeves 24 are fixedly connected to the screw sleeves 27 for engaging the transmission screw 28, and the middle parts of the two screw sleeves 27 penetrate the transmission screw 28, and the transmission screw 28 is meshed with the screw sleeves 27. The transmission screw 28 is movably connected between the two ends inside the base 26, and the top of the base 26 is fixedly connected to the second motor 29, and the output end of the second motor 29 penetrates the top of the base 26 and is fixedly connected to the top of the transmission screw 28 through a coupling;
