Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 - 7 , the present utility model provides an automatic roll cutting machine capable of freely adjusting the cutting angle, including a working platform 1, an activity member is provided on the working platform 1, a motor 2 is provided on the activity member, a cutting blade 3 is provided at the end of the motor 2, and a socket rod 4 is rotatably connected to the working platform 1; further including: a first rotating shaft 6 fixedly connected to the central axis of the cutting blade 3, an output shaft of the motor 2 is fixedly connected to a second rotating shaft 5, movable grooves 7 are provided at the ends of the first rotating shaft 6 and the second rotating shaft 5, and connecting shafts 8 are rotatably connected to both the first rotating shaft 6 and the second rotating shaft 5, and the two connecting shafts 8 are fixedly connected to each other;

[0026] A limiting member, the limiting member enables the cutting blade 3 to rotate around the connection point of the two connecting shafts 8;

[0027] In this application, first, by rotating the first rotating shaft 6, the sliding rod 14 slides along the circular groove 13, and the first rotating shaft 6 rotates in cooperation with the second rotating shaft 5, so as to adjust the angle of the cutting blade 3, and then through the limiting member, the inclined angle of the cutting blade 3 is maintained;

[0028] Then the material to be cut is sleeved on the socket rod 4;

[0029] Then, through the activity member, the inclined cutting blade 3 is pressed against the outer surface of the material to be cut;

[0030] Finally, make the socket rod 4 rotate on its own axis. In the prior art, the socket rod 4 drives the material to be cut to rotate on its own axis, and the motor 2 drives the cutting blade 3 to rotate at high speed on its own axis. The second rotating shaft 5 rotates on its own axis, driving the two connecting shafts 8 to rotate, thereby driving the first rotating shaft 6 to rotate on its own axis. At this time, the angle of the cutting blade 3 can be freely adjusted and fixed;

[0031] Moreover, through the movable part, the cutting blade 3 reciprocates to act on the material to be cut, and at the same time, the movable part moves along the direction of the sleeve pipe, thereby... to the material to be cut.

[0032] The movable part includes a conveying part and a first sliding plate 9. The conveying part makes the first sliding plate 9 slide along the direction of the socket rod 4. A second sliding plate 10 is slidably fitted on the first sliding plate 9. A cylinder 11 is fixedly connected to the first sliding plate 9. The air pressure rod of the cylinder 11 is fixedly connected to the second sliding plate 10;

[0033] Under the action of the conveying part, the first sliding plate 9 moves along the direction of the socket rod 4. Under the action of the cylinder 11, the second sliding plate 10 reciprocates to act on the material to be cut on the socket rod 4, thereby completing the movement of the cutting blade 3 along the direction of the material to be cut while making the cutting blade 3 reciprocate to act on the material to be cut (that is, the cutting blade 3 cuts the material to be cut at once and then moves away from the material to be cut).

[0034] The limiting part includes a protective cover 12 rotatably fitted with the cutting blade 3. The first rotating shaft 6 penetrates into the protective cover 12. A circular groove 13 is formed on the second sliding plate 10. A sliding rod 14 fixedly connected to the protective cover 12 is slidably fitted in the circular groove 13. A plurality of jacks 15 arranged in a circular matrix are formed on the working platform 1. A fixing plate 16 is fixedly connected to the sliding rod 14. A plug rod 17 movably fitted with the jack 15 is inserted and fitted on the fixing plate 16;

[0035] In this application, the movable protective cover 12 is moved, making the sliding rod 14 slide along the circular groove 13, thereby changing the angle between the cutting blade 3 and the protective cover 12. At the same time, the angle of the first rotating shaft 6 relative to the second rotating shaft 5 changes. At this time, the connecting shaft 8 rotates adaptively. At this time, the angle of the cutting blade 3 can be freely adjusted;

[0036] When the angle adjustment of the cutting blade 3 is completed, fixation is required. By moving the plug rod 17 located on the fixing plate 16, the plug rod 17 is inserted into the jack 15, thereby completing the fixation of the cutting blade 3 after the angle adjustment;

[0037] Among them, the jack 15 can be set as a threaded hole, and the plug rod 17 can be a screw rod. The screw rod is threadedly connected to the threaded hole to make the connection more tight.

[0038] The conveying member includes a motor 18 fixedly connected to the working platform 1. A threaded rod 19 rotatably connected to the working platform 1 is fixedly connected to the output shaft of the motor 18. The threaded rod 19 is threadedly connected to the first sliding plate 9, and the first sliding plate 9 is in sliding contact with the working platform 1.

[0039] The motor 18 drives the threaded rod 19 to rotate self - axially at the original position, thereby driving the first sliding plate 9 and the cutting blade 3 to move along the direction of the socket rod 4.

[0040] Two limiting rods 20 are fixedly connected to the working platform 1 on both sides of the threaded rod 19. The limiting rods 20 penetrate through the first sliding plate 9, and the first sliding plate 9 slides smoothly through the two limiting rods 20.

[0041] Two T - shaped blocks 21 are symmetrically distributed and fixedly connected to the top surface of the first sliding plate 9. A limiting groove 22 slidably matched with the T - shaped blocks 21 is formed on the bottom surface of the second sliding plate 10 to ensure that the second sliding plate 10 slides smoothly along the first sliding plate 9.

[0042] An insertion connection plate 23 connected to the socket rod 4 is inserted into the working platform 1. By removing the insertion connection plate 23, it is convenient for the material to be cut to be sleeved onto the socket rod 4. After the material to be cut is sleeved, the insertion connection plate 23 is re - inserted into the working platform 1 so that the material to be cut is stably sleeved on the socket rod 4.
