Referring to fig. 7 and 8, in some embodiments, the first winding mechanism 200 includes a first winding drum 210 and a cutting assembly 220, the cutting assembly 220 includes a cutting frame 210, a cutting knife 230, and a guide bar 220, and the guide bar 220 extends along the width direction of the adhesive tape 201, i.e., along the width direction of the frame 110. The cutting frame 210 is in sliding fit with the guide rod 220, so that the cutting frame 210 slides on the guide rod 220 in a reciprocating manner along the width direction of the machine frame 110, the first reel 210 is mounted on the cutting frame 210 and located above the machine frame 110, the first reel 210 is driven by the power source to rotate relative to the cutting frame 210, and the cut-off material 202 formed by the cut-off adhesive layer 22 and the cut-off protective layer 21 is wound on the first reel 210, that is, the first reel 210 plays a role in recovering the cut-off material 202. The cutting knife 230 may be a disk-shaped knife rotatably disposed on the cutting frame 210, and the disk-shaped knife rotates to generate a cutting force, so as to cut off the adhesive layer 22 and the protective layer 21 on the cut end 25 of the adhesive tape 201 (see fig. 1 to 3). Of course, the cutting depth of the disc-shaped knife can be adjusted by the fine adjustment micrometer, so that the situation that the base layer 23 is cut due to the fact that the cutting depth of the disc-shaped knife is too large is avoided. Therefore, when the disc knife cuts the tape 201, the cut-off material 202 is wound on the first reel 210. Because the cutting frame 210 can slide relative to the guide rod 220, the cutting assembly 220 can be suitable for processing adhesive tapes 201 with different widths, and meanwhile, the width of the cut-off material 202 can be adjusted. A sensor 240 may also be provided on the cutting frame 210, the sensor 240 being used for rotation of the first reel 210 to wind the cut material 202 for recycling.

Obviously, the first winding drum 210 and the second winding drum 310 are located on the same side (i.e. the upper side) of the frame 110, and since the cartridge 120 is located on the lower side of the frame 110, both the first winding drum 210 and the cartridge 120 are located on different sides of the frame 110, which can make full use of the space on the upper and lower sides of the frame 110, so that the whole glue cutting device 10 is more compact in structure.

The second guide roller 320 is positioned between the driving shaft 132 and the first guide roller 134 along the length direction of the frame 110, and the second guide roller 320 is positioned diagonally above the driving shaft 132. The second reel 310 is used for winding the remaining uncut protective layer 21 on the adhesive layer 22, and the remaining uncut protective layer is wound around the driving shaft 132 firstly, then reversely wound around the second guiding roller 320 and finally wound on the second reel 310, so as to realize the recovery of the protective layer 21 by the second reel 310. This enables the driving shaft 132 and the second guide roller 320 to form a sufficient tension to the holding layer so that the holding layer can be smoothly wound on the second bobbin 310.

When the adhesive cutting device 10 works, the driving shaft 132 is driven by the driver 131 to rotate continuously, and at the same time, the first winding drum 210, the second winding drum 310 and the cutting knife 230 are driven to rotate continuously. The rotating cutter 230 will cut the protective layer 21 and the adhesive layer 22 on the cutting end 25 to form the cut material 202, and the cut material 202 will be continuously wound on the first reel 210; the remaining protective layer 21, which is not necessarily cut off, will continue to be wound on the second reel 310 through the driving shaft 132 and the second guide roller 320 in this order; under the action of the driving shaft 132 and the driven shaft 133, the molded product 203 including the base layer 23 and the remaining uncut adhesive layer 22 is continuously discharged from the end of the frame 110.

Therefore, the adhesive tape 201 is processed into the molded product 203 through the adhesive tape cutting device 10, so that a part of the base layer 23 is free from being bonded with the adhesive layer 22 to form a free state with warping degree, and then the part of the base layer 23 in the free state is easy to be pinched and drives the whole base layer 23 to be quickly torn off from the adhesive layer 22, thereby improving the convenience of using the adhesive tape 201.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
