[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a paper tube cutting device.

[0034] Reference Figure 1 The paper tube cutting device includes a frame 1, a sliding seat 2, a drive assembly 3, and a cutting assembly 4. The frame 1 is arranged in a rectangular box shape, with its length oriented along the movement direction of the paper tube. The sliding seat 2 is slidably connected to the upper side of the frame 1, and its sliding direction is the length direction of the frame 1. The drive assembly 3 is located in the frame 1 and drives the sliding seat 2 to move.

[0035] Reference Figure 1 and Figure 2 In this embodiment, the driving assembly 3 includes a first driving motor 31, a first screw rod 32, a first slide rail 33 and a first slider 34. The first driving motor 31 is fixedly connected to the inner side wall of the frame 1. The first screw rod 32 is arranged along the length direction of the frame 1 and is rotatably connected to the frame 1. The power output shaft of the first driving motor 31 is fixedly connected to one end of the first screw rod 32 to drive the first screw rod 32 to rotate.

[0036] Meanwhile, a clearance slot 11 is defined along the length of the upper side of the frame 1. The sliding seat 2 extends into the frame 1 through the clearance slot 11 and is threadedly connected to the first screw rod 32. Two first slide rails 33 are provided and spaced apart along the width of the frame 1. The first slide rails 33 are fixedly connected to the upper side of the frame 1 via bolts. A plurality of first sliders 34 are fixedly connected to the lower side of the sliding seat 2. Each first slider 34 is slidably connected to a respective first slide rail 33 to enhance the stability of the sliding connection of the sliding seat 2 to the frame 1.

[0037] The cutting assembly 4 includes a mounting seat 41, a cutter 42, a second drive motor 43, and a drive member 44. The mounting seat 41 is slidably connected to the sliding seat 2 along the width direction of the frame 1. The cutter 42 is rotatably connected to one side of the mounting seat 41, and the rotation axis of the cutter 42 is arranged parallel to the length direction of the frame 1. The second drive motor 43 is fixedly connected to the mounting seat 41, and the power output shaft is fixedly connected to the cutter 42 to drive the cutter 42 to rotate. The drive member 44 is a cylinder. The drive member 44 is provided on the sliding seat 2, and the power output shaft is fixedly connected to the mounting seat 41 to drive the mounting seat 41 to move. In other embodiments, the drive member 44 can also be an oil cylinder, an electric push cylinder, etc., which is not limited in this application.

[0038] In actual use, the second drive motor 43 drives the cutter 42 to rotate, and the drive member 44 drives the mounting base 41 to move along the width of the frame 1, so that the cutter 42 approaches the paper tube to cut the paper tube. At the same time, the first drive assembly 3 drives the first screw 32 to rotate. Because the first screw 32 is threadedly connected to the sliding base 2 and the sliding base 2 moves through the cooperation of the first slide rail 33 and the first slider 34, the cutter 42 can move synchronously with the paper tube, and the paper tube can be cut without stopping the tube winding process, thereby improving paper tube production efficiency.

[0039] In some embodiments, the cutting assembly 4 also includes a second slide rail 45 and a second slider 46. The second slide rail 45 is arranged on the upper side of the sliding seat 2, and the second slider 46 is fixedly connected to the lower side of the mounting seat 41, and the second slider 46 is slidably connected to the second slide rail 45, thereby improving the sliding stability of the mounting seat 41, thereby improving the stability of the cutter 42 in cutting the paper tube.

[0040] Reference Figure 2 and Figure 3In some embodiments, the paper tube cutting device further includes an adjustment assembly 5. Specifically, the adjustment assembly 5 includes an adjustment seat 51, a second screw rod 52, and an adjustment handwheel 53. The adjustment seat 51 is slidably connected to the upper side of the sliding seat 2 along the width direction of the frame 1. The second screw rod 52 is arranged along the width direction of the frame 1 and is rotatably connected to the sliding seat 2. The second screw rod 52 is threadedly connected to the adjustment seat 51. The adjustment handwheel 53 is fixedly connected to one end of the second screw rod 52. The second screw rod 52 is rotated by the adjustment handwheel 53 to drive the adjustment seat 51 to move. Among them, the mounting seat 41 is slidably connected to the upper side of the adjustment seat 51, and the driving member 44 is fixedly connected to one end of the adjustment seat 51. The movement of the adjustment seat 51 drives the mounting seat 41 to move, so as to adjust the position of the mounting seat 41, so that the cutter 42 can cut paper tubes of different sizes, thereby improving the applicability of the paper tube cutting device. It should be noted that the position of the mounting seat 41 can also be adjusted by adjusting the stroke of the driving member 44, so that the paper tube cutting device can cut paper tubes of more sizes.

[0041] In some embodiments, the adjustment assembly 5 also includes a limit bolt 54, which is threadedly connected to the sliding seat 2. By rotating the limit bolt 54, the limit bolt 54 is made to abut against the peripheral side of the second screw rod 52 to limit the rotation of the second screw rod 52, thereby avoiding misoperation when the cutter 42 cuts the paper tube and causing the adjustment hand wheel 53 to rotate, thereby improving the stability of the cutter 42 in cutting the paper tube.

[0042] In some embodiments, the paper tube cutting device also includes a guide assembly 6. Specifically, the guide assembly 6 includes a mounting frame 61 and a rotating roller 62. The mounting frame 61 is fixedly connected to the upper side of the sliding seat 2, and the rotating roller 62 is rotatably connected to the upper side of the mounting frame 61. The rotating roller 62 is vertically arranged, that is, the axis of rotation of the rotating roller 62 is vertically arranged. The paper tube contacts the rotating roller 62 during the movement, and the rotating roller 62 guides the movement of the paper tube, thereby facilitating the movement of the paper tube.

[0043] In some embodiments, the guide assembly 6 also includes a locking bolt 63, and an adjustment slot 611 is provided on the lower side of the mounting frame 61 along the width direction of the frame 1. The lower end of the locking bolt 63 is movably passed through the adjustment slot 611 and is threadedly connected to the sliding seat 2. The upper end of the locking bolt 63 abuts against the mounting frame 61 to achieve a fixed connection between the mounting frame 61 and the sliding seat 2, and through the adjustment slot 611, the position of the mounting frame 61 can be adjusted to suit paper tubes of different sizes.

[0044] The operating principle of this embodiment is as follows: In actual use, the second drive motor 43 drives the cutter 42 to rotate, and the drive member 44 drives the mounting base 41 to move along the width of the frame 1, so that the cutter 42 approaches the paper tube to cut the paper tube. At the same time, the first drive assembly 3 drives the first screw 32 to rotate. Because the first screw 32 is threadedly connected to the sliding base 2 and the sliding base 2 moves through the cooperation of the first slide rail 33 and the first slider 34, the cutter 42 can move synchronously with the paper tube, and the paper tube can be cut without stopping the tube winding process, thereby improving paper tube production efficiency.

[0045] Among them, the first drive motor 31 and the first screw rod 32 are arranged in the frame 1, which improves the space utilization of the frame 1 to reduce the overall size of the paper tube cutting device, and has a simple structure and high movement accuracy of the sliding seat 2.

[0046] The embodiment of the present application also discloses a pipe reel.

[0047] The tube rolling machine includes the paper tube cutting device described in the above embodiment.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
