[0030] Reference Figure 1-Figure 3 According to an embodiment of a winding device in a slitting machine of the present invention, it includes two mounting plates 11 distributed front and back, a support rod 23 is fixed between the extension plates on the right side of the mounting plate 11, and the support rod 23 is externally rotatably connected to the front rocker arm 12 and the rear rocker arm 13, and also includes a driving component for driving the front rocker arm 12 and the rear rocker arm 13 to swing.

[0031] In addition, the rear rocker arm 13 is equipped with an intermediate rod 14 that can rotate and extend forward, and also includes a winding mechanism for driving the intermediate rod 14 to rotate. When the winding work is performed, the staff can put the reel on the outside of the intermediate rod 14. When the driving component drives the intermediate rod 14 to rotate, the reel put on the outside can also rotate, thereby performing the paper winding work.

[0032] In addition, in order to prevent the intermediate rod 14 from being broken due to being supported on only one side, a support assembly acting on the intermediate rod 14 is also provided on the front rocker arm 12. In this embodiment, the support assembly includes an inner tube rotatably connected to the front end of the intermediate rod 14, and a sliding sleeve 15 is fixed on the front side of the front rocker arm 12. A support sleeve slidingly connected to the sliding sleeve 15 and extending backward through the front rocker arm 12 is provided. The inner diameter of the support sleeve is adapted to the outer diameter of the inner tube. A No. 1 clutch cylinder 16 is fixed to the front end of the sliding sleeve 15, and a No. 1 piston rod in the No. 1 clutch cylinder 16 is connected to the support sleeve.

[0033] When the front rocker arm 12 and the rear rocker arm 13 are at the same angle, the No. 1 clutch cylinder 16 can control the support sleeve to move backward and make it sleeved outside the inner tube. At this time, the front end of the intermediate rod 14 is also supported. When the support sleeve is sleeved outside the inner tube, the front rocker arm 12 can be lifted alone so that the front end of the intermediate rod 14 is not blocked, so that the staff can carry out loading and unloading work on the intermediate rod 14.

[0034] In this embodiment, the driving mechanism includes push-pull cylinders 17 respectively hinged on the two mounting plates 11, and the ends of the No. 2 piston rods extending from the two push-pull cylinders 17 are respectively hinged to the sides of the front rocker arm 12 and the rear rocker arm 13. When the front end of the intermediate rod 14 is connected to the front rocker arm 12, the two push-pull cylinders 17 can work together and push and pull the reel on the intermediate rod 14. When the intermediate rod 14 is separated from the front rocker arm 12, the No. 2 piston rod in the push-pull cylinder 17 located on the front side can retract and lift the front rocker arm 12 alone to facilitate the loading and unloading of the intermediate rod 14.

[0035] In addition, the intermediate rod 14 is installed on the rear swing arm 13 in such a way that a sleeve 19 is fixedly provided in the rear swing arm 13, a transmission shaft 20 is rotatably connected in the sleeve 19, and the intermediate rod 14 is fixed to the front end of the transmission shaft 20, specifically, the flange at the rear end of the intermediate rod 14 is connected to the flange at the front end of the transmission shaft 20.

[0036] The winding mechanism includes a fixing plate 21 fixed to the rear side of the rear rocker arm 13 through a connecting plate 18, the transmission shaft 20 passes through the fixing plate 21 to extend to the rear side of the fixing plate 21, and the mounting plate 11 is equipped with a driving motor (not shown in the figure) for driving the transmission shaft 20 to rotate.

[0037] The specific connection method between the output shaft of the driving motor and the transmission shaft 20 is that the support rod 23 passes through the fixed plate 21 backward, and the support rod 23 is externally rotatably connected to two interconnected transmission sleeves. The transmission shaft 20 is connected to one of the transmission sleeves through a No. 1 synchronous belt 24, and the other transmission sleeve is connected to the output shaft of the driving motor through a No. 2 synchronous belt 25. When the driving motor is energized, the transmission sleeve will be driven to rotate through the No. 2 synchronous belt 25, and then the transmission shaft 20 and the intermediate rod 14 will be driven to rotate through the No. 1 synchronous belt 24.

[0038] Furthermore, a protective cover 26 for shielding the first synchronous belt 24 is provided on the outside of the fixing plate 21 , and a notch for accommodating the passage of the second synchronous belt 25 is provided inside the protective cover 26 .

[0039] In the second embodiment of the winding device in the slitting machine, the support rod 23 between the front rocker arm 12 and the rear rocker arm 13 is externally connected to a rotating drum 27, and the rotating drum 27 is equipped with an auxiliary support component that acts on the intermediate rod 14 to further improve the bearing capacity of the intermediate rod 14. In addition, the rear end of the rotating drum 27 is also fixed with a clutch plate 28, and the fixed plate 21 is fixed with a No. 2 clutch cylinder 29, and the end of the No. 3 piston rod in the No. 2 clutch cylinder 29 is equipped with a The clutch rod 30 is inserted into the rear rocker arm 13, and an adapter hole for accommodating the clutch rod 30 is provided in the clutch plate 28. When the No. 2 clutch cylinder 29 controls the clutch rod 30 to be inserted into the adapter hole, the clutch plate 28, the rotating drum 27 and the auxiliary support assembly thereon can take effect and assist in supporting the intermediate rod 14. When the clutch rod 30 leaves the adapter hole, the rotating drum 27 will cause the auxiliary support assembly to drop under the action of gravity and make it ineffective.

[0040] In this embodiment, the auxiliary support assembly includes a base plate 31, and two splints 32 distributed front and back are fixed on the base plate 31. A push plate extending to the right is rotatably connected between the two splints 32, and a support block 34 is provided on the push plate. The support block 34 is provided with an arc surface that can be attached to the curved surface of the intermediate rod 14, and the splint 32 is provided with a pneumatic component for controlling the angle of the push plate. The technical solution of controlling the swing of the push plate by using pneumatic components such as hinged cylinders and making the support block 34 attached to the intermediate rod 14 is a prior art and will not be repeated here.

[0041] In order to enable the push plate to adjust its position forward and backward, a slide plate 35 is fixed on the rotating drum 27, and the base plate 31 is slidably connected to the slide plate 35 forward and backward. A locking rod 36 that can abut against the slide plate 35 is also threadedly connected to the base plate 31. When the staff rotates the locking rod 36, the locking rod 36 can abut against the slide plate 35 and lock the position of the base plate 31.

[0042] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
