DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] The double-axis slitting machine currently in use has a winding method in which the cores are staggered on two winding shafts. For example, there are 1, 3, 5, and 7 reels on the A shaft, and 2, 4, 6, and 8 reels on the B shaft. This can prevent the two adjacent reels from biting together during the winding process.

[0023] Example 1

[0024] like Figure 1 and Figure 4 As shown, the core positioning device of the liner paper slitting machine is installed between the two winding shafts in the slitting machine, including a first gantry and a second gantry 1 rotatably connected to the first gantry, a positioning plate 2 is slidably connected to the second gantry 1, and the positioning plate 2 is slidably connected along the second gantry 1 transversely.

[0025] The first gantry is installed on the ground, the second gantry 1 is rotatably connected to the crossbar in the first gantry, and the number of the positioning plate 2 is at least one;

[0026] When installing the winding core, since the first gantry is installed between the two winding shafts, the positioning plate 2 can be made close to the two winding shafts by rotating the second gantry 1, and the positioning plate 2 is moved to align with the edge of the paper, and then the second gantry 1 is rotated to make the positioning plate 2 close to the two winding shafts, and then the position of the winding core is determined according to the position of the positioning plate 2.

[0027] The positioning plate 2 includes a connecting portion and a positioning portion. The connecting portion is slidably connected to the second gantry 1. The connecting portion is threadedly connected with a second fastening bolt 12 that abuts against the second gantry 1. The positioning plate 2 can be fixed at different positions on the second gantry 1 by adjusting the second fastening bolt 12. The positioning portion is a plate body that crosses the width direction of the second gantry 1. When positioning, one side of the positioning plate 2 rests on the left side of the first winding core of the A axis, and when reversed, the other side of the positioning plate 2 rests on the right side of the second winding core on the B axis.

[0028] In combination with the above, the present application can accurately adjust the position of the core according to the position of the slitting knife through the setting of the first gantry, the second gantry 1 and the positioning plate 2. The core position is accurately installed to ensure the quality of the finished product, and effectively solves the problem that the installation position of the core in the current slitting machine is difficult to determine.

[0029] Example 2

[0030] like Figure 1 and Figure 2 As shown, the structure of this embodiment is substantially the same as that of the embodiment 1, and this embodiment is further optimized on the basis of the embodiment 1, the first portal frame comprises two opposite upright posts 3 and a connecting rod 4 installed between the two upright posts 3, the second portal frame 1 is rotatably connected to the connecting rod 4, a traction spring 5 connected to the second portal frame 1 is installed on the connecting rod 4, the number of the traction springs 5 ​​is two and they are staggeredly installed on the connecting rod 4, and the two traction springs 5 ​​are respectively connected to the two sides of the second portal frame 1;

[0031] Since the distance between the two sides of the first gantry and the reeling shaft and the slitting knife is long, and the second gantry 1 is heavy, the traction spring 5 can provide traction for the rotation of the second gantry 1, making it convenient for the operator to rotate the second gantry 1;

[0032] The two traction springs 5 ​​are staggeredly arranged on the connecting rod 4, and can provide traction force when the second portal frame 1 is close to the winding shafts on both sides.

[0033] A positioning rod 10 is horizontally installed on the second portal frame 1, and a spring positioning pin 13 is installed in the middle of the positioning rod 10. A positioning hole 11 adapted to the spring positioning pin 13 is vertically opened on the upper side of the connecting rod 4. The spring positioning pin 13 can be made to leave the positioning hole 11 by pulling the spring positioning pin 13 or turning the second portal frame 1 with force, so as to rotate the second portal frame 1; when it is not necessary to position the winding core, the spring positioning pin 13 is automatically inserted into the positioning hole 11 by turning the second portal frame 1 to a vertical state, so as to fix the position of the second portal frame 1.

[0034] Example 3

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the structure of this embodiment is roughly the same as that of embodiment 2. This embodiment is further optimized on the basis of embodiment 2. The two ends of the connecting rod 4 are respectively slidably connected with the two columns 3. A lateral adjustment hand wheel 6 is rotatably installed on any column 3, and a gear 7 is installed on the lateral adjustment hand wheel 6. A rack 8 matched with the gear 7 is installed in parallel on the connecting rod 4. By rotating the lateral adjustment hand wheel 6, the connecting rod 4 can be driven to move laterally between the two columns 3, so as to facilitate the positioning of multiple winding cores staggered on the two winding shafts; a first fastening bolt 9 for abutting the connecting rod 4 is threadedly connected on any column 3, and the first fastening bolt 9 abuts the connecting rod 4 to fix the connecting rod 4 after it moves laterally.

[0036] In order to facilitate the adjustment of the position of the positioning plate 2, a laser lamp 14 is installed on the connecting rod 4. The laser lamp 14 illuminates the slitting knife below. There is a scale on the slitting knife shaft which can be used as a base point. By adjusting the connecting rod 4 as a whole, the second gantry 1 is driven to move, and then the position of the positioning plate 2 is adjusted according to the width of the core to determine the core position.

[0037] At present, the technical solution of this application has been put into pilot production, that is, a small-scale experiment before the large-scale mass production of the product; after the pilot production was completed, a user usage survey was carried out in a small range, and the survey results showed that user satisfaction was high; now we have begun to prepare for the formal production of the product for industrialization (including intellectual property risk warning survey).
