[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The embodiments of the present application disclose a high-transmittance PET tape that is easy to tear.

[0033] Reference Figure 1 、 Figure 2 and Figure 5 A high-transmittance PET tape that is easy to tear comprises a tape body 1. The tape body 1 is sleeved with a connecting tube 2. A connecting block 3 is fixedly connected to one side of the connecting tube 2. A horizontal plate 4 is fixedly connected to the side of the connecting block 3 close to the tape body 1. A rotating plate 5 is hinged to one side of the horizontal plate 4. A knife seat 6 is slidingly provided on the top of the horizontal plate 4. A plurality of cutting knives are fixedly connected to the end of the knife seat 6 away from the horizontal plate 4 at equal intervals. A limiting mechanism is provided on the top of the knife seat 6, and a protective mechanism is provided on the outer surface of the connecting tube 2.

[0034] When in use, first put the tape body 1 on the outside of the connecting tube 2, then pull out a piece of tape, and place this piece of tape body 1 on the top of the guide roller 7. The guide roller 7 is used to guide the direction of the tape to ensure that the tape can be pasted smoothly. When in use, paste one end of this piece of tape body 1 on the verified position, and then pull the tape body 1 hard to move it to one side so that the tape body 1 is evenly pasted on the target surface. When it needs to be cut, move the cross plate 4 downward. At this time, the top of the tape body 1 conflicts with the pressure roller 8, and the cross plate 4 drives the knife seat 6 downward, so that the cutting knife cuts the tape body 1. The knife seat 6 can be moved by the limiting mechanism so that the knife seat 6 is no longer exposed, reducing the risk of the cutting knife scratching the staff. The risk of the tape body 1 falling off the connecting tube 2 during work can be reduced by the protective mechanism.

[0035] Reference Figure 1 、 Figure 3 and Figure 4The limiting mechanism includes a vertical plate 9 fixedly connected to the top of the knife seat 6, a movable plate 10 is slidably provided on one side of the vertical plate 9, a handle 11 is fixedly connected to the top of the movable plate 10, and two driving rods 12 are symmetrically fixedly connected to the side of the movable plate 10 away from the vertical plate 9. The bottom ends of the driving rods 12 on both sides are fixedly connected with a locking rod 13, and locking grooves 14 are equidistantly provided on both sides of the top of the horizontal plate 4, and the locking rods 13 are engaged with the locking grooves 14.

[0036] Elastic members 15 are fixedly connected to both sides of the top of the transverse plate 4 . The elastic member 15 is composed of a telescopic rod and a spring. The top of the elastic member 15 is fixedly connected to the bottom of the movable plate 10 .

[0037] In addition, guide blocks 16 are symmetrically fixedly connected on both sides of the movable plate 10, and guide rods 17 are fixedly connected on both sides of the top of the transverse plate 4. The top ends of the guide rods 17 pass through the guide blocks 16, and the guide rods 17 are slidably connected to the guide blocks 16.

[0038] In addition, two groups of limit seats 19 are symmetrically fixedly connected to the top two sides of the horizontal plate 4, and limit grooves are provided inside the limit seats 19. Positioning blocks 20 are symmetrically fixedly connected to the two sides of the knife seat 6, and the positioning blocks 20 are adapted to the limit grooves.

[0039] In addition, sliding grooves 18 are opened on both sides of the top of the horizontal plate 4, and sliding blocks are fixedly connected to both sides of the bottom of the knife seat 6. The sliding blocks are adapted to the sliding grooves 18 and are slidably connected to the sliding grooves 18.

[0040] When adjusting the position of the knife holder 6, first pull the handle 11 to drive the movable plate 10 to move upward, and the movable plate 10 will drive the spring 1 to stretch upward. When the spring stretches to generate elastic potential energy, the movable plate 10 will drive the driving rod 12 to move upward, and the upward movement of the driving rod 12 will drive the locking rod 13 to disengage the locking groove 14, thereby contacting the restriction of the knife holder 6, and then the knife holder 6 will slide, so that the locking rod 13 moves to the top of the locking groove 14 on the other side. At this time, the staff releases the handle 11 again, so that the elastic potential energy of the spring 1 is released, thereby driving the movable plate 10 downward, so that the locking rod 13 is locked and connected with the locking groove 14 on the other side, so that the knife holder 6 is no longer exposed. By adjusting the position of the knife holder 6, it is no longer exposed when not in use, reducing the risk of staff being cut by the knife during operation and transportation;

[0041] When the movable plate 10 moves up and down, the guide block 16 and the guide column provide the movable plate 10 with additional support points, so that the movable plate 10 remains stable during movement. When the knife holder 6 slides on the horizontal plate 4, the knife holder 6 will drive the positioning blocks 20 on both sides to move. The positioning blocks 20 can be limited by the limit seat 19, so that the knife holder 6 can remain in the correct position after the movement is completed. When the knife holder 6 is moving, the slider and the slide groove 18 provide a guiding effect for the knife holder 6, so that the knife holder 6 maintains the correct motion trajectory when moving.

[0042] Reference Figure 5 The protective mechanism includes an internal thread 21 opened on the inner side of the connecting tube 2, a baffle 22 is provided on one side of the connecting tube, and a connecting tube 2 23 is fixedly connected to the side of the baffle 22 close to the connecting tube 2. An external thread is opened on the outer side of the connecting tube 23, and the internal thread 21 is threadedly connected to the external thread.

[0043] After the tape body 1 is placed on the connecting tube 1 2, the staff places the connecting tube 2 23 inside the connecting tube 1 2 and rotates the connecting tube 2 23, and the connecting tube 2 23 is threadedly connected with the internal thread 21 through the external thread, so that the connecting tube 2 23 is fixed inside the connecting tube. At this time, the baffle 22 is fixed on one side of the connecting tube 1 2. The baffle 22 can limit the tape body 1, thereby reducing the risk of the tape body 1 falling from the connecting tube 2, so that the tape body 1 can be stably maintained in the correct position, reducing the risk of the tape falling due to improper operation or vibration, thereby improving work efficiency and continuity.

[0044] Working principle: Put the tape body 1 on the outside of the connecting tube 2, then pull out a piece of tape, and place this piece of tape body 1 on the top of the guide roller 7. When in use, stick one end of this piece of tape body 1 to the verified position, and then pull the tape body 1 with force so that the tape body 1 is evenly stuck on the target surface. When it needs to be cut, move the horizontal plate 4 downward, and the horizontal plate 4 drives the knife holder 6 downward so that the cutting knife cuts the tape body 1. Pull the handle 11 to disengage the engaging rod 13 from the engaging groove 14, and then slide the knife holder 6 so that the engaging rod 13 moves to the top of the engaging groove 14 on the other side. At this time, the staff releases the handle 11 again, so that the engaging rod 13 is engaged with the engaging groove 14 on the other side, so that the knife holder 6 is no longer exposed. By adjusting the position of the knife holder 6, it is no longer exposed when not in use.

[0045] The staff places the connecting tube 23 inside the connecting tube 1 2 and rotates the connecting tube 23, and connects the connecting tube 23 with the internal thread 21 through the external thread, so that the connecting tube 23 is fixed inside the connecting tube. At this time, the baffle 22 is fixed on one side of the connecting tube 1 2. The baffle 22 can limit the tape body 1, thereby reducing the risk of the tape body 1 falling off the connecting tube 1 2.
