[0023] Please see Figures 1 to 4A slitting machine winding arm mechanism 10 includes a vertical plate 101, a first support shaft 102 mounted on the vertical plate 101, a support arm 103 rotatably mounted on the end of the first support shaft 102, an air expansion shaft 104 mounted on the end of the support arm 103 away from the first support shaft 102, a first connecting member mounted below the support arm 103 and rotatably connected at one end to the middle of the support arm 103, a second connecting member 105 mounted on the end of the first connecting member away from the support arm 103 and rotatably connected to the first connecting member, and a connecting member mounted on the second connecting member. A second support shaft 106, located away from the first connector and rotatably connected to the second connector 105, and a first drive cylinder 107, mounted above the second connector 105 and rotatably connected to the end of the second connector 105 near the first connector, are provided. The end of the second connecting shaft is connected to the upright plate 101. The bottom of the first drive cylinder 107 is rotatably connected to the upright plate 101. When the power output end of the first drive cylinder 107 extends to its maximum path, the first connector and the second connection are on the same axis.
[0024] Specifically, in this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 This diagram shows the overall configuration of the slitting machine's take-up arm mechanism 10 in its non-use state. Figure 2 This diagram shows the structure of the slitting machine's winding mechanism in its non-use state, where the first drive cylinder 107 is in the retracted state; as shown... Figure 3 As shown in the figure, the working state of the slitting machine winding arm mechanism 10 is illustrated. At this time, the first drive cylinder 107 extends, thereby driving the first rotating component and the second rotating component to rotate relative to each other. This, in turn, drives the support arm 103 to swing upward along the first support shaft 102, thereby driving the air expansion shaft 104 to move upward. When the first rotating component and the second rotating component are on the same axis, the first drive cylinder 107 extends to its maximum length. At this time, the entire structure remains stable, thus effectively supporting the air expansion shaft 104. Since the force on the first drive cylinder 107 is downward and the cylinder shaft extends to its maximum length, compared with the traditional method of the first drive cylinder 107 supporting the air expansion shaft 104 upward, it can effectively prevent the support arm 103 from falling due to insufficient air pressure, thereby improving the stability of the structure and making it suitable for industrial applications.
[0025] Furthermore, two upright plates 101 are arranged side by side, and the two ends of the first support shaft 102 and the second support shaft 106 are respectively installed on the two upright plates 101.
[0026] The slitting machine winding arm mechanism 10 of this utility model, through the arrangement of the upright plate 101, the first support shaft 102, the support arm 103, the first connector, the second connector 105, the second support shaft 106 and the first drive cylinder 107, can stably support the air expansion shaft 104 and is suitable for industrial applications.
[0027] In one specific embodiment, the first connecting member includes a load-bearing rod 108, a first hinge bolt 109, and a second hinge bolt 110. The first hinge bolt 109 and the second hinge bolt 110 are respectively installed at both ends of the load-bearing rod 108, with the first hinge bolt 109 rotatably connected to the middle of the support arm 103, and the second hinge bolt 110 rotatably connected to the end of the second connecting member 105 away from the second support shaft 106. Specifically, the first hinge bolt 109 and the second hinge bolt 110 are rotatably connected to the support arm 103 and the second rotating member respectively via pins.
[0028] In one specific embodiment, the two ends of the load-bearing rod 108 are provided with threaded holes for installing the first hinge bolt 109 and the second hinge bolt 110.
[0029] In one specific embodiment, the bottom of the first drive cylinder 107 is rotatably connected to the upright plate 101 via a single lug 119. Further, the end of the support arm 103 away from the first support shaft 102 is provided with a bayonet 111 for mounting the air expansion shaft 104. Further, a clamping assembly is also included, mounted on the support arm 103, for clamping the air expansion shaft 104 so that the air expansion shaft 104 is confined within the bayonet 111.
[0030] In one specific embodiment, the clamping assembly includes a take-up clamp head 112, a take-up clamp head top member 113, and a second drive cylinder 114; the support arm 103 is provided with a mounting groove 115 communicating with the bayonet 111; the take-up clamp head 112 is installed in the mounting groove 115, and the middle part of the take-up clamp head 112 is rotatably connected to the support arm 103, so that the take-up clamp head 112 has a first working state in which it rotates toward the bayonet 111 and extends from the mounting groove 115 into the bayonet 111 to abut against the air expansion shaft 104 in the bayonet 111, and has a second working state in which it rotates away from the bayonet 111 to return to the mounting groove 115; winding The take-up head top member 113 is installed in the mounting groove 115 and located at the end of the take-up head 112 away from the latch 111. A slot for engaging the end of the take-up head 112 is provided on the side of the take-up head top member 113 that is in contact with the take-up head 112. A second drive cylinder 114 is installed on the side of the support arm 103 and connected to the take-up head top member 113, used to drive the take-up head top member 113 to move within the mounting groove 115. When the take-up head top member 113 moves within the mounting groove 115, it drives the take-up head 112 to move relative to it within the slot, allowing the take-up head 112 to switch between a first working state and a second working state as needed. Specifically, in this embodiment, the middle part of the take-up head 112 is rotatably connected to the support arm 103 within the mounting groove 115 via a pin. Furthermore, when the take-up head 112 is in the first working state, the take-up head top member 113 is perpendicular to the take-up head 112. When it is necessary to switch the take-up head 112 to the second working state, the second drive cylinder 114 drives the take-up head top member 113 to move, so that the take-up head 112 moves relative to each other in the slot, so that the take-up head 112 leaves the slot 111 and returns to the mounting slot 115. Furthermore, the slot includes a notch 116 for the take-up head 112 to fit in the first working state, and an inclined step 117 provided on the side of the notch 116 for the take-up head 112 to move when the take-up head 112 changes from the first working state to the second working state. Specifically, in this embodiment, when the take-up chuck 112 is in the first working state, one end of the take-up chuck 112 is located in the recess 116. Since the take-up chuck top member 113 is connected to the second drive cylinder 114 and is in a stable state, the other end of the take-up chuck 112 is firmly pressed against the air expansion shaft 104 located in the bayonet 111. When it is necessary to release the pressing state, the second drive cylinder 114 drives the take-up chuck top member 113 to move, so that the take-up chuck 112 moves gradually under the drive of the recess 116, and gradually fits against the inclined step 117 during the movement, so that the end of the take-up chuck 112 near the bayonet 111 leaves the bayonet 111, so that the take-up chuck 112 switches to the second working state; the reverse is also true.Furthermore, at one end of the take-up chuck 112 near the air expansion shaft 104, there is an arc-shaped pressing part 120 for the take-up chuck 112 to press against and fit against the air expansion shaft 104 in the first working state. In this embodiment, the arc-shaped pressing part 120 is provided so that the take-up chuck 112 can be securely confined within the slot 111 in the first working state.
[0031] Furthermore, the power output end of the first drive cylinder 107 is rotatably connected to the end of the second connector 105 near the first connector via a third hinge bolt 118.
[0032] The slitting machine winding arm mechanism 10 of this utility model, through the arrangement of the upright plate 101, the first support shaft 102, the support arm 103, the first connector, the second connector 105, the second support shaft 106 and the first drive cylinder 107, can stably support the air expansion shaft 104 and is suitable for industrial applications.
[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
