[0023] See also Figure 1-4, the utility model provides an embodiment: an improved automatic tape cutting machine, comprising a machine body 1, a symmetrically arranged bearing seat is fixedly installed on one side of the upper surface of the machine body 1, a symmetrically arranged fixed seat 2 is fixedly installed on the other side of the upper surface of the machine body 1, a screw rod 3 is rotatably connected between the two groups of bearing seats, a light rod 4 is fixedly installed between the two groups of fixed seats 2, a threaded block 5 is sleeved on the outer surface of the screw rod 3, the threaded block 5 is threadedly connected to the screw rod 3, a moving block 6 is slidably sleeved on the outer surface of the light rod 4, one end of the screw rod 3 is fixedly connected to the output shaft of the servo motor 7, a tape cutting frame 8 is fixedly installed between the threaded block 5 and the moving block 6, a pneumatic cylinder 9 is fixedly installed at the center position of the upper surface of the tape cutting frame 8, the output end of the pneumatic cylinder 9 is movably connected to the pneumatic rod, and the bottom end of the pneumatic rod is fixedly installed with a tape cutting seat 10;

[0024] According to the above structure, when it is necessary to dynamically adjust the length of the tape cut by the tape cutting seat 10, the servo motor 7 can be rotated. When the servo motor 7 rotates, it will synchronously drive the screw rod 3 to rotate through the output shaft. Since the external thread of the screw rod 3 is connected to the thread block 5, when the screw rod 3 rotates, the thread block 5 thereon will move linearly left and right, thereby driving the tape cutting frame 8 and the one side moving block 6 to move synchronously through the movement of the thread block 5, so that the dynamic adjustment of the tape cutting length can be completed through the dynamic left and right adjustment of the tape cutting frame 8 and the cutter seat 10.

[0025] In this embodiment, in order to ensure the normal use of the tape cutting machine, a metal heat conductive member 14 is fixedly installed at the center of the lower surface of the tape cutting seat 10, a heating wire 15 is fixedly installed inside the metal heat conductive member 14, and a cutter 16 is fixedly installed on the lower surface of the metal heat conductive member 14;

[0026] In this structural design, a heating wire 15 is arranged in the metal heat conductor 14, and the metal heat conductor 14 can be heated by the arranged heating wire 15, so that the heat is transferred to the cutter 16 through the metal heat conductor 14, so that the cutter 16 can be heated, and the thermal cutting work of the strip can be completed by the heated cutter 16;

[0027] Among them, both sides of the lower surface of the tape cutting seat 10 are provided with limit holes 11, and springs 12 are fixedly installed in the two limit holes 11;

[0028] Furthermore, the bottom ends of the two springs 12 are fixedly mounted with limit posts 13, and the limit posts 13 are in sliding contact with the limit holes 11;

[0029] With this structural design, when the tape cutting seat 10 is driven by the pneumatic cylinder 9 to descend, the limiting column 13 will first contact the cutting table surface. During the continuous descending process, the limiting column 13 will compress the spring 12 at the top, thereby playing a certain impact protection effect through the elastic reaction force of the spring 12, and having a certain buffer protection characteristic;

[0030] Furthermore, the process of the limiting column 13 retracting into the limiting hole 11 can provide a limiting guide function for the linear displacement of the downward pressure, prevent deviation, and have a moving guide function.

[0031] In this embodiment, a tape feed bracket 17 is fixedly mounted on the outer wall of one end of the upper surface of the body 1, and a tape feed opening 18 is arranged inside the tape feed bracket 17;

[0032] A plurality of linear and evenly spaced spring pieces 19 are fixedly mounted on the outer wall of one side of the belt feed bracket 17, and the spring pieces 19 are smooth metal spring pieces;

[0033] In actual use, a tape feeding mechanism may be installed at one end of the tape feeding bracket 17, so that the tape is fed through an external tape feeding mechanism;

[0034] The delivered tape body is transferred from one end to the other end through the tape inlet 18, and then cut by the tape cutting mechanism;

[0035] The spring sheet 19 can be used to perform preliminary compression on the belt body to avoid bending and improve the use effect.

[0036] In this embodiment, in order to ensure the normal functional operation of the tape cutter of the utility model, a control panel 20 is provided on the outer surface of the body 1, and the control panel 20 is composed of a display screen and a plurality of physical buttons;

[0037] In order to ensure the normal desktop use of the body 1 and to make it have certain desktop anti-skid properties, anti-skid bottom pads 21 are fixedly attached to the four corners of the lower surface of the body 1 by glue, and the anti-skid bottom pads 21 are made of anti-skid rubber.

[0038] Working principle: When the utility model is used, the belt cutter can be placed on a work surface and powered on to ensure normal power supply;

[0039] In actual use, a tape feeding mechanism may be installed at one end of the tape feeding bracket 17, so that the tape is fed through an external tape feeding mechanism;

[0040] The distance between the cutter seat 10 and the tape feeding bracket 17 is adjusted according to the actual tape length requirement;

[0041] The adjustment method is as follows: the servo motor 7 can be rotated. When the servo motor 7 rotates, it will synchronously drive the screw rod 3 to rotate through the output shaft. Since the screw rod 3 is externally threaded with a thread block 5, when the screw rod 3 rotates, the thread block 5 thereon will move linearly left and right, thereby driving the cutting frame 8 and the one side moving block 6 to move synchronously through the movement of the thread block 5, so that the cutting frame 8 and the cutting knife seat 10 can be dynamically adjusted left and right to complete the dynamic adjustment of the cutting length;

[0042] The delivered belt body is transmitted from one end to the other end through the belt inlet 18. At this time, the pneumatic cylinder 9 provided on the barrel can drive the belt cutting seat 10 at the bottom to descend. When the belt cutting seat 10 descends under the drive of the pneumatic cylinder 9, the limit column 13 will first contact with the cutting table. In the continuous descending process, the limit column 13 will compress the spring 12 at the top, thereby playing a certain impact protection effect through the elastic reaction force of the spring 12, and having a certain buffer protection characteristic;

[0043] At the same time, a heating wire 15 is provided in the metal heat conductive member 14, and the metal heat conductive member 14 can be heated by the provided heating wire 15, so that the heat is transferred to the cutter 16 through the metal heat conductive member 14, so that the cutter 16 can be heated. The heated cutter 16 is driven by the pneumatic cylinder 9 to descend, and when it finally contacts the strip, the heated cutter 16 can complete the thermal cutting of the strip.

[0044] After the cutting of a single strip is completed, the pneumatic cylinder 9 performs up and down reciprocating motion and cooperates with the strip feeding mechanism to perform intermittent strip feeding, thereby completing the cyclic cutting of the strip.

[0045] The utility model is used in conjunction with a threaded transmission structure, so that the threaded transmission can drive the tape cutting frame and the tape cutting seat to perform synchronous linear displacement, thereby the spacing between the tape cutting end and the tape feeding end can be adjusted, and the cutting length of the tape body can be dynamically adjusted by increasing or decreasing the spacing distance, so that the tape cutting machine of the utility model can produce tape bodies of different lengths according to actual tape cutting needs, effectively increasing the size range of the cut tape, thereby effectively increasing the scope of application of the utility model, reducing the limitation of use, having a better use effect, and the overall structure is simple, can be directly placed on the desktop for use, occupies a small area, is convenient to transport, and is suitable for popularization and use.
