Generally, a plurality of cutter holders 1 are arranged on the slitting machine to meet the slitting requirements of films with different widths, and the connecting part 11 of the cutter holder 1 is slidably and fixedly arranged on the rack 6 in the embodiment, so as to adjust the position of the cutter holder, and further adjust the spacing between the plurality of cutter holders 1 arranged on the slitting machine, so as to cut films with different widths. The upper end of the connecting part 11 is slidably and fixedly arranged on the rack 1, which is a conventional technical means in the art. For example, a sliding groove is arranged on one side of the rack, the connecting part is slidably arranged in the sliding groove, and a screw rod passes through the connecting part and is fixed in the sliding groove. Of course, those skilled in the art can also arrange other structures according to actual requirements, which will not be described here.

[0026] In the embodiment, please refer to Figure 1 and Figure 2 , the bottom of the cutter holder 1 is provided with a rotating connection assembly 7, so as to rotatably arrange the infrared marking device 3 on the cutter holder 1. Specifically, please refer to Figures 3-5The rotating connecting assembly 7 comprises a connecting seat 71 and a connecting block 72. The connecting seat 71 is fixedly arranged at the bottom of the mounting portion 12 of the cutter holder 1. One end of the connecting block 72 is arranged at the connecting seat 71. The other end of the connecting block 72 is rotatably provided with a first rotating shaft 73. The infrared marker 3 is fixedly arranged at the outer periphery of the first rotating shaft 73, so that the infrared marker 3 is rotatably arranged at the cutter holder 1. Specifically, the cutting line of the cutter 2 is located on the plane where the rotating track of the infrared marker 3 is located, so as to facilitate rotating the infrared marker 3 to a certain position (first position), so that the infrared line emitted by the infrared marker 3 can irradiate on the separation line formed on the film to be cut, and the cutting line of the cutter 2 on the film to be cut coincides with the separation line, that is, the infrared line emitted by the infrared marker 3 irradiates on the film to be cut to form the separation line corresponding to the cutting line of the cutter 2.

[0027] In order to increase the flexibility and range of motion of the connecting block 72, in the embodiment, referring to Figures 3-5 The connecting seat 71 is C-shaped and is fixedly arranged at the bottom of the mounting portion 12 of the cutter holder 1 with the opening downward. Specifically, the connecting seat 71 comprises a first connecting plate 711 and second connecting plates 712 arranged on both sides of the first connecting plate 711. The first connecting plate 711 is fixedly arranged at the bottom of the mounting portion 12. The second connecting plates 712 extend vertically downward. The first connecting plate 711 and the second connecting plates 712 on both sides form a space 710 for accommodating one end of the connecting block 72. Two second connecting plates 712 are respectively provided with sliding grooves 7121 extending in the front-rear direction (two-end direction). One end of the connecting block 72 extends into the space 710 and is rotatably fixedly arranged on the two second connecting plates 712 and can slide along the sliding grooves 7121. Specifically, the screw rod 713 passes through the sliding groove 7121 on the second connecting plate 712 on one side from the outside of the second connecting plate 712, passes through one end of the connecting block 72, and then passes through the sliding groove 7121 on the other second connecting plate 712. The two ends of the screw rod 713 are respectively located outside the two second connecting plates 712, and the two nuts 714 are respectively sleeved on the two ends of the screw rod 713 from the outside of the two second connecting plates 712 and are tightened. Through the above design, by loosening and tightening the nuts 714, on the one hand, the rotating angle of the connecting block 72 relative to the connecting seat 71 can be adjusted, and on the other hand, the position of the connecting block 72 can be changed by moving the connecting block 72 on the sliding grooves 7121, so as to increase the flexibility of the connecting block 72 and the flexibility of the infrared marker 3.

[0028] In the embodiment, in order to facilitate the infrared marker 3 not to be affected by the blocking of the connecting block 72 during the rotation of the first rotating shaft 73, the connecting block 72 can be designed as a hollow structure, so that the infrared marker 3 has sufficient rotating space during the rotation of the first rotating shaft 73.

[0029] In the present embodiment, since the winding film on the paper tube 5 of each winding station 4 has two edges, the winding film edge on the paper tube 5 of each winding station 4 is correspondingly provided with a rotatably arranged infrared marker 3 on its corresponding cutter holder 1.

[0030] In some embodiments, since a single cutter 2 is usually divided into two after cutting the film, two film edges are generated, the present embodiment can further increase a complete set of connecting block 72, first rotating shaft 73, infrared marker 3, rotating connection assembly 7 and stop assembly 8 on the connecting seat 71, that is, two infrared markers 3 composed of the above structure can be rotatably arranged on the same cutter holder 1 to meet the alignment needs of another winding film edge.

[0031] In some embodiments, the cutter 2 is detachably arranged on the cutter holder 1, when the cutter 2 is not needed, the cutter can be detached, and the rotatably arranged infrared marker on the cutter holder 1 is used as an auxiliary device for the alignment of the winding film edge.

[0032] In the present embodiment, please refer to Figures 3-5 , the two ends of the first rotating shaft 73 respectively pass through the two sides of the connecting block 72, and one end of the first rotating shaft 73 is provided with a rocking handle 74. The rocking handle 74 is arranged to facilitate the driving of the first rotating shaft 73 to rotate, thereby driving the infrared marker 3 to rotate around the outer periphery of the first rotating shaft 73. The other end of the first rotating shaft 73 is provided with a stop assembly 8 for limiting the rotation of the first rotating shaft 73 when the first rotating shaft 73 is not driven to rotate. When the rocking handle 74 is not driven, the stop assembly 8 limits the rotation of the first rotating shaft 73; when the rocking handle 74 is driven, the first rotating shaft 73 can overcome the limiting action of the stop assembly 8 to rotate.

[0033] In the present embodiment, please refer to Figure 4The stop assembly 8 comprises a rolling ratchet 81, a stop pawl 82, and a resilient member 83 (in this embodiment, the resilient member 83 is a spring). The rolling ratchet 81 is fixedly sleeved on the other end of the first rotating shaft 73, and the outer periphery of the rolling ratchet 81 is provided with a plurality of ratchet teeth 811. One end of the stop pawl 82 is rotatably arranged on one side of the connecting block 72, and the other end of the stop pawl 82 is engaged in one of the ratchet teeth 811 of the rolling ratchet 81. One end of the resilient member 83 is fixed on one side of the connecting block 72 and is spaced from the one end of the stop pawl 82, and the other end of the resilient member 83 is fixedly arranged at the middle portion of the stop pawl 82, so that the resilient member 83 provides a spring force to make the other end of the stop pawl 82 engaged in one of the ratchet teeth 811 of the rolling ratchet 81. When the first rotating shaft 73 is driven to rotate, the other end of the stop pawl 82 is disengaged from the ratchet tooth 811 against the action of the resilient member 83, so as to realize the rotation of the first rotating shaft 73. When the driving of the first rotating shaft 73 is stopped, the other end of the stop pawl 82 is engaged in the ratchet tooth 811 under the action of the resilient member 83, so as to limit the rotation of the first rotating shaft 73. In this embodiment, due to the presence of the stop assembly 8, the shaking handle 74 can only rotate in one direction, i.e., the first rotating shaft 73 can only rotate in one direction (clockwise or counterclockwise).

[0034] In this embodiment, please refer to Figure 2 The winding station 4 comprises a first winding arm 41 and a second winding arm 42. The first winding arm 41 is provided with a first clamping head 43, and the second winding arm 42 is provided with a second clamping head 44. The two ends of the paper tube 5 are respectively clamped on the first clamping head 43 and the second clamping head 44. The first winding arm 41 and the second winding arm 42 are respectively slidably fixedly arranged on a base, and the distance therebetween is adjustable, which is a conventional technical means in the field and will not be described herein.

[0035] In this embodiment, the auxiliary structure for the paper tube alignment of the slitting machine winding station further comprises a sensing and alarming unit. The sensing and alarming unit comprises a sensor (not shown in the figure), a controller (not shown in the figure), and an alarm 9. The alarm is arranged on the rack 1. The sensor and the alarm 9 are respectively electrically connected to the controller. The sensor is used to detect the distance from the edge of the winding film to the alignment line. The sensor is provided with a distance setting value (in this embodiment, the distance setting value is 2.5 mm). When the sensor detects that the distance from the edge of the winding film to the alignment line is greater than the distance setting value (2.5 mm), the controller controls the alarm 9 to alarm, reminding the staff to adjust the position of the paper tube 5 or adjust the winding station 4.

[0036] The auxiliary structure for the paper tube alignment of the slitting machine winding station of the embodiment can be used in the following manner: first, rotate the infrared marking device 3 to make the infrared line emitted by the infrared marking device 3 irradiate on the cutting line formed on the film to be cut, and make the cutting line coincide with the tangent line of the cutter 2 on the film to be cut (i.e., rotate to the first position, so as to cut the film with the correct width); then, rotate the infrared marking device 3 to make the infrared line emitted by the infrared marking device 3 irradiate on the paper tube 5 of the winding station 4 to form an alignment line (i.e., rotate to the second position), which is the contrast line of the edge of the film after the film is cut and wound on the paper tube (referred to as the wound film), so that the staff can conveniently and intuitively observe the position of the edge of the wound film wound on the paper tube 5, and better adjust the alignment and positioning of the winding station 4, so as to avoid the winding quality problem caused by the inward indentation of the paper tube 5 due to the deviation of the winding station 4, and improve the equipment operation efficiency and the cutting quality.
