DETAILED DESCRIPTION

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-4 As shown, a BOPP adhesive tape mother roll slitting device comprises a mounting frame 1, a rotating shaft 2 is arranged on the mounting frame 1, a cutting blade 3 is arranged on the rotating shaft 2, a first motor 4 for driving the rotating shaft 2 to rotate is arranged on one side of the mounting frame 1, fixing devices are arranged on both sides of the mounting frame 1, the fixing devices comprise a base 5, a bracket 6 is arranged on the base 5, a feeding shaft 7 is arranged on the bracket 6, a mother roll 8 is mounted on the outer surface of the feeding shaft 7, a positioning block 9 is arranged at one end of the feeding shaft 7, a fixing plate 10 is threadedly connected to the other end of the feeding shaft 7, and a fixing shaft 11 is symmetrically arranged on the upper surface of the end of the base 5 away from the bracket 6. The fixed shaft 11 is tilted and a roller 12 is arranged on the fixed shaft 11. The outer surface of the roller 12 abuts against the outer surface of the mother roll 8. An adjusting frame 13 is arranged on one side of the mounting frame 1. A slider 14 is slidably connected inside the adjusting frame 13. The upper end of the slider 14 is connected to the upper end of the adjusting frame 13 by a tension spring 15. A second motor 16 is arranged on one side of the slider 14. Friction wheels 17 are arranged on the output end of the second motor 16 and one end of the unloading shaft 7. The three friction wheels 17 are connected by a friction belt 18. A sliding mechanism is arranged on the mounting frame 1. The sliding mechanism is used to control the two fixing devices to move closer or farther away from each other.

[0018] The first motor 4 can drive the rotating shaft 2 and the cutting blade 3 to rotate, so as to realize the slitting of the mother roll 8. When the cutting blade 3 cuts the mother roll 8, it realizes the slitting of the mother roll 8 by controlling the movement and rotation of the mother roll 8. The cutting blade 3 only rotates itself, and its position does not change.

[0019] When placing the mother roll 8 on the fixing device, first unscrew the fixing plate 10 from one end of the unloading shaft 7, and then install the mother roll 8 on the unloading shaft 7, and one end of the mother roll 8 abuts against the positioning block 9. The presence of the positioning block 9 enables the mother roll 8 to be evenly cut with minimal waste. After the mother roll 8 is placed on the unloading shaft 7, the fixing plate 10 is threadedly connected to the unloading shaft 7, and the mother roll 8 is squeezed by the fixing plate 10 to be fixed between the positioning block 9 and the fixing plate 10, so that the mother roll 8 can be driven to rotate synchronously by the rotation of the unloading shaft 7. When placing the mother roll 8, the mother roll 8 and the unloading shaft 7 can be supported by the roller 12 to reduce the swing amplitude of the unloading shaft 7 near the end of the fixing plate 10.

[0020] A supporting mechanism is provided on one side of the mounting frame 1, and the supporting mechanism includes a shell 24, and a limit block 25 is symmetrically provided inside the shell 24, and the limit block 25 is slidably connected to the shell 24, and an anti-slip block 26 is provided at the tail end of the limit block 25, and a spring 27 is provided between the two anti-slip blocks 26. When the fixing device moves toward the direction of the rotating shaft 2, the fixed plate 10 on the discharge shaft 7 can enter the limit block 25, and one side of the limit block 25 is open, so as to further reduce the swing amplitude of the discharge shaft 7 near the fixed plate 10 end, and the limit block 25 can move in the shell 24, so as to reduce the length of the limit block 25 to prevent obstruction to the placement of the mother roll 8, and the spring 27 can make the two limit blocks 25 always extend to the outside of the shell 24, so that the fixed plate 10 on the discharge shaft 7 can enter the inside of the limit block 25 as soon as possible.

[0021] When the fixing devices on both sides of the mounting frame 1 are in the initial state, the distance between the fixing devices and the rotating shaft 2 is the farthest, and the distance between the second motor 16 and the bottom end of the adjusting frame 13 is the shortest. At this time, the tension spring 15 is in a stretched state, and the tension spring 15 pulls the slider 14 upward through its elastic force, so that the friction belt 18 and the three friction wheels 17 are kept in a relatively tight state, so that the fixed shafts 11 on both sides of the mounting frame 1 are driven to rotate by the second motor 16 at the same time. When the mother roll 8 is completed after slitting, the distance between the fixing device and the rotating shaft 2 is the shortest. At this time, under the action of the tension spring 15, the slider 14 is driven to move upward, so that the friction belt 18 is still in a tensioned state, the tension spring 15 is still in a stretched state, and there is still a large friction force between the friction belt 18 and the friction wheel 17. At this time, the second motor 16 can simultaneously drive the fixed shafts 11 on both sides of the mounting frame 1 to rotate. When the mother roll 8 on the fixing device moves toward the rotating shaft 2, the second motor 16 drives the unwinding shaft 7 and the mother roll 8 on the unwinding shaft 7 to rotate continuously, so as to realize the slitting of the mother roll 8.

[0022] Furthermore, the sliding mechanism includes a guide module and a power module, and the guide module and the power module both include extension plates 19 symmetrically arranged on both sides of the mounting frame 1, wherein a guide rod 20 is arranged between the two extension plates 19 in the guide module, and a bidirectional screw rod 21 is arranged between the two extension plates 19 in the power module, and the bidirectional screw rod 21 is driven by a third motor 22, and a fixing block 23 corresponding to the sum of the number of the guide rods 20 and the bidirectional screw rods 21 is arranged on the lower surface of the base 5, wherein the inner portion of the fixing block 23 matched with the guide rod 20 is A through hole is opened, and a threaded hole is opened inside the fixing block 23 which cooperates with the bidirectional screw rod 21. When controlling the mother roll 8 to move in the direction of the rotating shaft 2, the bidirectional screw rod 21 is driven to rotate by the third motor 22. The bidirectional screw rod 21 is threadedly connected to the fixing block 23, and the remaining fixing blocks 23 are slidably connected to the guide rod 20, so that the two bases 5 can be prompted to move in the direction of the rotating shaft 2 at the same time. After the slitting of the mother roll 8 is completed, the two bases 5 are controlled to move in the direction away from the rotating shaft 2 at the same time, so as to facilitate the unloading of the mother roll 8 after slitting.

[0023] Furthermore, the sliding mechanism includes an extension plate 19 arranged on both sides of the mounting frame 1, and a hydraulic cylinder is arranged on the extension plate 19. The output end of the hydraulic cylinder is fixedly connected to the base 5. The movement of the base 5 is controlled by the extension and retraction of the output end of the hydraulic cylinder, thereby controlling the distance between the mother roll 8 on the base 5 and the rotating shaft 2.

[0024] Furthermore, a protective cover 28 is provided on the upper portion of the mounting frame 1 , and the safety of the device can be improved by the protective cover 28 .

[0025] Working principle: two mother rolls 8 are placed on the unloading shaft 7 respectively, and the mother rolls 8 are fixed between the positioning block 9 and the fixed plate 10 through the threaded connection between the fixed plate 10 and the unloading shaft 7, and then the first motor 4, the second motor 16, and the third motor 22 are started at the same time. The first motor 4 drives the rotating shaft 2 and the cutting blade 3 to rotate, the second motor 16 drives the mother roll 8 on the unloading shaft 7 to rotate, and the third motor 22 controls the mother roll 8 to move toward the rotating shaft 2. Through the movement and rotation of the mother roll 8, it can be cut into several small rolls by the cutting blade 3, thereby completing the slitting of the mother roll 8.

[0026] The device can simultaneously cut two mother rolls 8 through a plurality of cutting blades 3 on a rotating shaft 2, which can effectively save the time of moving and cutting the mother rolls 8, effectively improve the cutting efficiency, and has a good use effect.
