The side of the tape guide groove 51 is connected to the inlet end 511 and the outlet end 512. A side opening with a width not less than the width of the tape 1 is provided between the outlet ends 512; in the embodiment of the present application, the structure of the tape guide bracket 5 is optimized, and a tape guide groove 51 is provided on the tape guide bracket 5 to guide the tape 1. The tape guide groove 51 adopts a side-open structure, that is, a side opening is provided on its side. When the tape is passed through the tape guide groove 51, the tape can enter the guide groove 51 through the side opening, which facilitates the tape 1 to pass through the tape guide groove 51, improves the convenience of the tape threading operation, and avoids the situation in the prior art that the tape 1 is easily bent and obstructed when passing through a narrow and long material guide hole that is closed on all sides.

[0026] In a further embodiment of the present invention, Figure 2 As shown, the tape guide bracket 5 is provided with a tape guide wheel 52 at the inlet end 511, and the extension line of the tape guide groove 51 is tangent to the outer edge of the tape guide wheel 52; in the present embodiment, the tape guide wheel 52 structure is arranged so that the tape enters the tape guide groove 51 after passing through the tape guide wheel 52, and the direction of the tape 1 is changed by the tape guide wheel 52 and remains smooth during the conveying process.

[0027] In a further embodiment of the present invention, Figure 2 and Figure 4 As shown, a hollow portion 53 is provided in the middle of the tape guide bracket 5, the tape guide groove 51 passes through the hollow portion 53, and a clamping mechanism 6 for clamping the tape 1 is provided in the hollow portion 53, and the clamping mechanism 6 is driven by a linear drive component to move along the direction of the tape guide groove 51; in this scheme, the hollow portion 53 structure in the middle of the tape guide bracket 5 is provided to provide a movable space for the clamping mechanism 6 to move, and the clamping mechanism 6 is used to clamp and release the tape. After the clamping mechanism 6 clamps the tape, the clamping mechanism 6 is driven by the linear drive component 8 to move along the direction of the tape guide groove 51 to drive the tape forward. After the clamping mechanism 6 releases the tape, it is driven back by the linear drive component for the next conveying, and this is repeated to achieve continuous conveying of the tape.

[0028] In a further embodiment of the present invention, Figure 5As shown, the clamping mechanism 6 includes a mounting seat 61 that can move along the direction in which the tape guide groove 51 is set, a clamping seat 62 fixed on the mounting seat 61 and located in the hollow portion 53, and a clamping block 64 driven by a clamping cylinder 63 to move in the direction close to and away from the clamping seat 62, a clamping groove 65 is formed between the clamping seat 62 and the clamping block 64, and one side of the clamping groove 65 is open, and the clamping cylinder 63 is installed on the mounting seat 61; in this solution, the clamping cylinder 63 drives the clamping block 64 to move, the clamping cylinder 63 drives the clamping block 64 close to the clamping seat 62 so as to clamp the tape 1 in the clamping groove 65, and the clamping cylinder 63 drives the clamping block 64 away from the clamping seat 62 so as to release the tape 1.

[0029] In a further embodiment of the present invention, Figure 4 As shown, a slide rail assembly is provided between the mounting seat 61 and the tape guide bracket 5, and the slide rail assembly includes a slider 66 and a guide rail 67 that are connected in a cooperative manner.

[0033] Furthermore, the tape pressing mechanism 7 in this embodiment includes a pressing rod 71 for extending into the tape guide groove 51 to press the tape 1 and a driving cylinder 72 for driving the pressing rod 71 to move in the direction of pressing and releasing the tape 1. The driving cylinder 72 can be fixed on the tape guide bracket 5. The driving cylinder 72 drives the pressing rod 71 to move into the tape guide groove 51 to press the tape, and the driving cylinder 72 drives the pressing rod 71 to move away from the tape guide groove 51 to separate from the tape.

[0034] In a further embodiment of the present invention, Figure 1 and Figure 2 As shown, the release layer receiving mechanism 3 includes a winding frame 31 for winding the tape release layer 12 and a driving motor 32 for driving the winding frame 31 to rotate and recycle the tape release layer 12.
