The end of the piston rod of the moving cylinder 43 is fixedly connected to the seat body 42, and the seat body 42 moves horizontally repeatedly along the slide rail 33 under the drive of the moving cylinder 43; the mounting frame 44 is fixedly mounted on the upper end of the seat body 42; the clamping lower block 45 is fixedly mounted on one end of the mounting frame 44 close to the tape holder 6; the clamping upper block 46, the clamping upper block 46 presses one end of the transfer plate 5 against the upper surface of the clamping lower block 45 through bolts, and one end of the transfer plate 5 is clamped between the clamping upper block 46 and the clamping lower block 45. Further, the slider 41 is slidably mounted in the slide rail 33, and under the drive of the moving cylinder 43, the slider 41 slides repeatedly along the setting direction of the slide rail 33, thereby driving the transfer plate 5 to slide repeatedly. In another preferred embodiment, the upper clamping block 46 and the lower clamping block 45 are fixed with bolts. Specifically, the bolts penetrate the upper clamping block 46, the transfer plate 5 and the lower clamping block 45 from top to bottom, so that the transfer plate 5 can be cleaned and replaced more conveniently.

When the tape roll 7 is subjected to the pulling force, the pulling force is transmitted along the tangential direction of the tape roll 7, so that the longer extended end 71 of the tape roll 7 is released and rotates with the limiting shaft 63.

[0051] Further, as a preferred embodiment, the cutting mechanism 8 includes: a pressing base plate 64, which is fixedly mounted on the upper part of one end of the hollow seat 62 close to the movable seat 4; a pressing cylinder 65, which is fixedly mounted on the other end of the accommodating space, and the pressing cylinder 65 is arranged below the pressing base plate 64, and the piston rod of the pressing cylinder 65 is arranged vertically upward; a pressing block 66, which is fixedly mounted on the upper end of the piston rod of the pressing cylinder 65, and the pressing block 66 is arranged opposite to the lower surface of the pressing base plate 64, and the pressing block 66 can be operated to press the extended end 71 against the lower surface of the pressing base plate 64 under the drive of the pressing cylinder 65; an upper cutter 67, which is arranged on the pressing base plate 6 4 is close to one end of the movable seat 4, and the upper cutter 67 is arranged vertically downward; a cutting cylinder 81, which is arranged in the accommodating space, and is arranged on the side of the pressing cylinder 65 close to the movable seat 4, and a certain distance is left between the cutting cylinder 81 and the movable cylinder 43, and the piston rod of the cutting cylinder 81 is arranged in the vertical direction; a cutter mounting member 82, and the cutter mounting member 82 is fixedly mounted on the piston rod of the cutting cylinder 81; a lower cutter 83, which is fixedly mounted on the cutter mounting member 82, and is arranged in the vertical direction directly opposite to the upper cutter 67, and the lower cutter 83 can be operably moved upward under the drive of the cutting cylinder 81 and cuts and shears the extended end portion 71 together with the upper cutter 67. Furthermore, the clamping base plate 64 and the clamping block 66 serve as a clamping mechanism for clamping the extended end portion 71 of the tape roll 7. The clamping mechanism is arranged on the side of the cutter portion close to the tape roll 7. In actual use, the extended end portion 71 is adhered to the transfer plate 5. The clamping block 66 fixes the end of the tape extended end portion 71 close to the tape roll 7 to the lower surface of the clamping base plate 64 under the action of the clamping cylinder 65. The lower cutter 83 moves upward under the action of the cutting cylinder 81 and is closely interlaced with the upper cutter 67 to form a cutting effect similar to scissors, completing the cutting of the extended end portion 71 to form a tape strip.
