[0012] Figure 2 It is a cross-sectional view of the utility model;

[0013] Figure 3 for Figure 2 A partial enlarged view of point A in the middle. DETAILED DESCRIPTION

[0014] like Figure 1 As shown, this stable film-releasing shaft mechanism is installed on a die-cutting machine and realizes passive rotation through traction of a traction mechanism, thereby providing film material.

[0015] like Figure 2 As shown, this stable film placing shaft mechanism includes a support 1 and a film placing shaft 6, a bearing seat 2 is mounted on the support 1, and the film placing shaft 6 is mounted on the bearing seat 2 through a bearing, that is, the film placing shaft 6 can rotate on the bearing seat 2. Figure 3 As shown, the outer end of the film placing shaft 6 has a threaded end 60, the diameter of the threaded end 60 is smaller than the diameter of the film placing shaft 6 (the support sleeve 3 can be placed outside the adjusting screw sleeve 7), the threaded end 60 is externally threadedly connected with the adjusting screw sleeve 7, the adjusting screw sleeve 7 is connected to the adjusting knob 5, the outer sleeve of the film placing shaft 6 is provided with a support sleeve 3, the support sleeve 3 is placed outside the adjusting screw sleeve 7, and the outer end of the support sleeve 3 is stuck on one side of the adjusting knob 5, as shown in FIG. Figure 2As shown, a first spring 14 is sleeved on the film placing shaft 6, and the first spring 14 acts on the support sleeve 3 to drive the support sleeve 3 to move in the direction of the adjusting knob 5. In addition, a positioning screw 61 is radially threaded on the film placing shaft 6, and a long hole 30 extending along the axial direction is provided on the support sleeve 3, and the positioning screw 61 passes through the long hole 30.

[0016] The adjustment principle of this film-releasing shaft mechanism is as follows: when it is necessary to adjust the left and right positions of the film roll, just twist the adjusting knob 5. Since the adjusting knob 5 is connected to the adjusting screw sleeve 7, the adjusting screw sleeve 7 also rotates accordingly. Since the adjusting screw sleeve 7 is threadedly connected to the threaded end 60 of the film-releasing shaft 6, the adjusting screw sleeve 7 and the adjusting knob 5 move axially together. Since the supporting sleeve 3 leans against the side of the adjusting knob 5 under the action of the first spring 14, the adjusting knob 5 moves and the supporting sleeve 3 also moves accordingly, so that the position of the film roll on the supporting sleeve 3 can be adjusted; and the positioning screw 61 can limit the supporting sleeve 3 to move only axially on the film-releasing shaft 6, preventing the supporting sleeve 3 from rotating relative to the film-releasing shaft 6, so that the rotation of the film-releasing shaft 6 can drive the supporting sleeve 3 to rotate.

[0017] In order to make the rotation of the film-releasing shaft 6 have a certain damping to prevent the film roll from automatically moving due to inertia, only the traction mechanism pulls the film material forward. Figure 1 As shown, a connecting plate 10 is sleeved on the film unloading shaft 6, and the connecting plate 10 can move axially on the film unloading shaft 6, and a friction plate 9 is connected to the connecting plate 10, and a wear-resistant plate 8 is connected to the support 1, and a pressure regulating knob 12 is threadedly connected to the end of the film unloading shaft 6, and a second spring 11 is provided between the pressure regulating knob 12 and the connecting plate 10, and the second spring 11 drives the friction plate 9 to act on the wear-resistant plate 8, so that the rotation of the film unloading shaft 6 has a certain damping.

[0018] In order to allow the connection disk 10 to move axially on the film placing shaft 6 and allow the film placing shaft 6 to rotate with the connection disk 10, the connection hole of the connection disk 10 has a keyway (not shown), and the film placing shaft 6 is provided with an axially extending limit key (not shown), and the limit key is located in the keyway. With this structure, the connection disk 10 can move axially on the film placing shaft 6 and allow the film placing shaft 6 to rotate with the connection disk 10 through the limit key.

[0019] The adjusting screw sleeve 7 is provided with a bearing 70 outside, and the bearing 70 is located between the adjusting screw sleeve 7 and the supporting sleeve 3. The bearing 70 can reduce the resistance between the adjusting screw sleeve 7 and the supporting sleeve 3, so that the supporting sleeve 3 moves more smoothly.

[0020] In order to limit the left and right movement of the film roll, Figure 1As shown, two limiting plates 4 are installed on the support sleeve 3, and the limiting plates 4 include a connecting portion 40 and a limiting portion 41. The connecting portion 40 is provided with a screw hole, and a bolt is provided in the screw hole, and the bolt can act on the support sleeve 3. By moving the position of the limiting plate 4 on the support sleeve 3, after determining the position, tighten the bolt, and fix the limiting plate 4 on the support sleeve 3, the limiting portion 41 has a limiting effect on the film roll.

[0021] Finally, it is worth mentioning that a positioning piece 13 is connected to the film placing shaft 6, one end of the first spring 14 acts on the positioning piece 13, and the other end of the first spring 14 acts on the support sleeve 3. In this way, the first spring 14 gives the support sleeve 3 a rightward thrust (such as Figure 2 to the right in the image).
