Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0028] Embodiment one:

[0029] Combined Figures 1-4 The utility model discloses a kind of slitting machine winding roller self-positioning locking rocker shown in the drawing, including slitting machine 1, slitting machine 1 is equipment main body, its internal cavity provides the space environment for winding roller 2 to rotate, winding roller 2 one end is driven rotation stably in the cavity of slitting machine 1 by support structure, for the winding operation of material after slitting, to realize the collection of material on winding roller 2, locking rocker assembly 3 for supporting the other end of winding roller 2 is provided on the side wall of slitting machine 1, for winding operation of material after slitting;

[0030] The locking rocker arm assembly 3 comprises a support base 301 fixed on the side wall of the slitting machine 1, which is firmly fixed on the side wall of the slitting machine 1 through a bolt connection component, providing stable basic support for the entire locking rocker arm assembly 3, and a rocker arm 302 is arranged inside the support base 301 through rotation, which can rotate within a certain angle range with the rotation center, a bearing 303 is arranged on the side wall of the rocker arm 302, the inner ring of the bearing 303 matches the outer contour shape and size of the end portion of the winding roller 2, so as to realize the close fit between the end portion of the winding roller 2 and the inner ring of the bearing 303, while ensuring the flexible rotation of the winding roller 2, the winding roller 2 is provided with reliable radial support, a pin hole 304 is opened above the end of the rocker arm 302 close to the support base 301, at the same time, a raised platform 305 is arranged above the support base 301, which plays a role in lifting the height of the subsequent components, a dividing pin assembly 306 matched with the pin hole 304 is arranged on the raised platform 305, so that the dividing pin assembly 306 and the pin hole 304 can accurately correspond in the vertical direction, when the rocker arm 302 is rotated to the appropriate position, the dividing pin assembly 306 is inserted into the pin hole 304, so as to lock the rocker arm 302 at the fixed position, realizing the positioning and locking of the winding roller 2.

[0031] The support base 301 in the embodiment is in U-shaped structure, the rocker arm 302 is rotatably connected between the two inner side walls of the U-shaped structure, the two side walls of the U-shaped structure play a limiting and guiding role for the rocker arm 302, effectively preventing the rocker arm 302 from being axially offset during rotation, providing a stable and accurate support foundation for the rotation of the rocker arm 302, ensuring that the rocker arm 302 can remain stable when supporting the winding roller 2, and improving the reliability of the overall structure.

[0032] In the embodiment, a limiting plate 307 for limiting the rotation angle of the rocker arm 302 is arranged on the support base 301, which is installed on the support base 301 by a reliable fixing method such as welding or bolt connection, and the limiting plate 307 is accurately located on the rotation path of the rocker arm 302, when the rocker arm 302 rotates around the connecting point with the support base 301, it will come into contact with the limiting plate 307 when reaching the preset maximum rotation angle, on the one hand, it can prevent the rocker arm 302 from over-rotating, ensuring the safety and stability of the equipment, on the other hand, reasonable rotation angle limitation enables the rocker arm 302 to accurately position the end portion of the winding roller 2 during work, ensuring the accuracy of subsequent winding operation.

[0033] In the embodiment, a hollow groove is opened in the middle of the rocker arm 302, which effectively reduces the overall weight of the rocker arm 302, and makes the rocker arm 302 more flexible and light during rotation under the premise of ensuring the structural strength and rigidity of the rocker arm 302.

[0034] The outer handle 308 is arranged on the upper surface of the rocker arm 302 away from the pin hole 304 in this embodiment. When the rocker arm 302 needs to be rotated, the operator only needs to hold the outer handle 308 easily, and then the rocker arm 302 can be driven to rotate around the support bottom piece 301 by means of the lever principle with smaller force, which significantly reduces the operation difficulty and improves the work efficiency.

[0035] The bearing 303 and the rocker arm 302 are connected in a sleeving manner in this embodiment. This connection manner is based on precise size matching design to ensure that the bearing 303 can be stably fixed on the rocker arm 302 after installation, reduce the vibration and noise generated by loosening during the rotation of the winding roller 2, and the connection part between the bearing 303 and the rocker arm 302 is uniformly coated with high-strength anti-loosening glue. The anti-loosening glue has good adhesion and filling properties, can penetrate into the small gap between the bearing 303 and the installation hole of the rocker arm 302, and further enhances the connection strength between the two.

[0036] The index pin assembly 306 is a key component for reliably locking the rocker arm 302 in this embodiment. It mainly includes an index pin sleeve 3061. The top of the index pin sleeve 3061 is carefully provided with a guide slope 3062 with a certain inclination angle and a smooth surface. An “L”-shaped pin shaft 3063 is arranged in the inside of the index pin sleeve 3061. The unique design of the “L” shape makes the pin shaft 3063 form a stable locking structure after being inserted into the pin hole 304. A anti-loosening ring 3064 is arranged at the middle position of the pin shaft 3063. The anti-loosening ring 3064 is tightly sleeved on the pin shaft 3063, which can prevent the pin shaft 3063 from coming out of the index pin sleeve 3061 during use. A spring 3065 is arranged between the anti-loosening ring 3064 and the cavity of the index pin sleeve 3061. The spring 3065 has a suitable elastic coefficient and pre-tightening force. When the rocker arm 302 is rotated to the position and the pin shaft 3063 is inserted into the pin hole 304, the spring 3065 generates a downward elastic force, which makes the pin shaft 3063 tightly inserted into the pin hole 304, ensuring the locking effect of the rocker arm 302. When the rocker arm 302 needs to be unlocked, the pin shaft 3063 is rotated along the guide slope 3062 by overcoming the elastic force of the spring 3065 and pulled upward, so that the index pin assembly 306 is unlocked, and the rotation of the rocker arm 302 is easily realized, which is simple and convenient to operate.
