Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, specifically the clutch swing arm in the winding and cutting mechanism of a die-cutting machine. Background Technology

[0002] After the roll material is wound and cut, it needs to be sealed to prevent it from loosening. This requires rotating the roll to another position for sealing. This rotation is achieved by using a turntable on one side of the shaft. Since the other side needs to pull the roll material off the shaft, this side of the shaft is open. To prevent the shaft from shifting, a swing arm is usually used on the open side. One end of the swing arm clamps the shaft containing the roll material. The swing arm rotates synchronously when the turntable rotates. After sealing, the swing arm reverses to return to its original position and continues to clamp the other shaft. Currently, the head of the swing arm that clamps the shaft uses two nylon parts. Because the roll material needs to rotate during sealing, friction occurs between the nylon parts of the swing arm and the shaft, which can easily damage these parts. It also increases the load on the shaft drive, increasing the risk of damage. After the nylon parts wear down, the gap between the swing arm and the shaft becomes larger, failing to prevent the shaft from wobbling. Over time, this can cause the shaft to loosen and deform, affecting the winding quality. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] Please see Figure 1 and Figure 2 The figure shows a roll material winding and cutting clutch swing arm 2, including a mounting plate 1 and a swing arm 2. The mounting plate 1 is fixed on a rotating sleeve 3. The inner wall of the rotating sleeve 3 is provided with a mounting bearing 4. The rotating sleeve 3 is mounted on a shaft-like part. The rotating sleeve 3 is connected to a drive assembly that drives the rotating sleeve 3 to rotate. The drive assembly is prior art and is not related to the technical problem to be solved in this application, so it will not be described in detail here. The swing arm 2 is fixed on the mounting plate 1. A movable clamping mechanism is provided between the swing arm 2 and the mounting plate 1. The movable clamping mechanism includes a moving arm 5 and a drive mechanism that drives the moving arm 5 to reciprocate linearly. The drive mechanism drives the moving arm 5 to reciprocate to clamp and release the rotating shaft. In this embodiment, the swing arm 2 itself serves as the fixed clamping end of the clamping mechanism, and works with the moving arm 5 to achieve movable clamping of the rotating shaft. The setting of this clamping mechanism ensures that the rotating shaft can be clamped every time it is clamped. Even if the clamping mechanism is worn, the moving arm 5 can still hold the rotating shaft, avoiding the risk of shaking under wear conditions. The stability is higher, and the rotating shaft runs more smoothly in the long term, resulting in a low maintenance rate.

[0018] In this embodiment, the driving mechanism includes a linear guide rail 6 and a slider 7 disposed between the movable arm 5 and the mounting plate 1, and also includes a driving source 8 that drives the movable arm 5 to move. The output end of the driving source 8 is connected to the movable arm 5. The linear guide rail 6 is fixed on the mounting plate 1, and the slider 7 is fixed on the movable arm 5. Alternatively, the installation can be reversed, i.e., the linear guide rail 6 is fixed on the movable arm 5, and the slider 7 is fixed on the mounting plate 1.

[0019] In this embodiment, the drive source 8 is installed on the side of the mounting plate 1 away from the guide rail 6. Since there is a large distance between the drive source 8 and the moving arm 5, a transmission rod 9 is fixed on the moving arm 5 in this embodiment. The drive source 8 is a cylinder, and the piston rod of the cylinder is fixedly connected to the transmission rod 9. The piston rod of the cylinder extends and retracts, driving the transmission rod 9 and the moving arm 5 connected to the transmission rod 9 to reciprocate along the guide rail 6. The reciprocating motion of the moving arm 5 can clamp or release the rotating shaft.

[0020] The clamping mechanism in this embodiment further includes a first bearing 10 mounted on the swing arm 2, and a second bearing 11 and a third bearing 12 mounted on the movable arm 5. The second bearing 11 and the third bearing 12 are arranged side-by-side, and the line connecting the midpoint of the second bearing 11 and the third bearing 12 to the center point of the first bearing 10 is aligned with the direction of movement of the movable arm 5. In this embodiment, the second bearing 11 and the third bearing 12 are fixed to the movable arm 5 by fasteners or shafts, and the outer rings of the bearings can rotate after the second bearing 11 and the third bearing 12 are fixed. A recessed clearance groove 13 is provided at the corresponding gap position between the end of the movable arm 5 and the second bearing 11 and the third bearing 12. In this embodiment, the contact position between the clamping mechanism and the rotating shaft is set with multiple bearings. Through the contact between the bearings and the rotating shaft, the bearings themselves rotate when the rotating shaft rotates, thus changing the original sliding friction to rolling friction in this embodiment, reducing friction and almost eliminating wear. This area requires almost no maintenance, improving product quality.

[0021] In this embodiment, the first bearing 10 is fixed to the adjusting block 14 by fasteners or a shaft. After the first bearing 10 is fixed, the outer ring of the bearing can rotate. The adjusting block 14 is fixed to the swing arm 2, and the fastener mounting hole on the adjusting block 14 connected to the swing arm 2 is provided with an adjustable mounting gap. In this embodiment, the adjustable mounting gap is achieved by designing the mounting hole as a long groove structure, so that the fastener has a large mounting gap. The mounting position of the adjusting block 14 is adjusted by the adjustable mounting gap. In this embodiment, the setting of the adjusting block 14 not only serves to fix the first bearing 10, but also adjusts the mounting position of the first bearing 10, so that the rotating shaft can contact all three bearings. The three bearings form a triangle. By utilizing the stability of the triangle, the rotating shaft can be stably locked between the three bearings and rotate.

[0022] In this embodiment, a pressure block 15 is also fixedly installed on the swing arm 2. The pressure block 15 is provided with a set screw 16, and the end of the set screw 16 abuts against the adjusting block 14. The setting of the pressure block 15 prevents the position of the adjusting block 14 from changing during long-term use, thereby making it less likely for the first bearing 10 to be displaced after the position is fixed, and ensuring the stability of the equipment operation.
