The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

The lace cutter of the adhesive tape shown in fig. 1 and 2 comprises a frame 100, wherein a carrying shaft mechanism 300 for carrying a large roll of the adhesive tape to be cut and a cutting mechanism 200 for cutting laces on two sides of the large roll are respectively arranged on the frame.

Specifically, the cutting mechanism 200 includes a bracket 210 mounted on a frame, and two lifting mechanisms 220 are symmetrically disposed on two sides of the bracket 210, where the lifting mechanisms may use telescopic cylinders or telescopic hydraulic cylinders. At the end of one of the lifting mechanisms 220 is provided a sleeve one 240, which is rotatably connected to the lifting mechanism. At the same time, a screw sleeve 250 is fixedly connected to the end of the other lifting mechanism 220, said screw sleeve being arranged coaxially to the sleeve, and a sleeve two 260 being screwed into the screw sleeve. The second shaft sleeve is a self-lubricating shaft sleeve, and the second shaft sleeve is driven to rotate in the threaded sleeve so as to realize axial movement of the second shaft sleeve in the threaded sleeve. In addition, a rotating shaft 290 is disposed between the two lifting mechanisms 220, one end of the rotating shaft passes through the first shaft sleeve and is in driving connection with a first motor 230 fixedly connected with the first shaft sleeve, and the other end of the rotating shaft is rotatably inserted into the second shaft sleeve so as to keep the rotating shaft stable when the adhesive tape is cut in large rolls. In addition, it should be noted that two sets of cutter wheel assemblies 280 are further disposed on the rotating shaft, and the cutter wheel assemblies can perform axial position adjustment on the rotating shaft so as to adapt to the lace cutting requirements of large rolls of adhesive tapes with different widths.

Working principle: when the knife wheel assembly 280 is to be replaced, the worker rotates the second sleeve 260 to withdraw the second sleeve from the end of the shaft, and then the worker pulls the shaft, which is rotatably connected with the first motor, and the first motor, which is connected with the shaft, around the first sleeve, and the lifting mechanism. And along with the rotation of the rotating shaft, one end of the rotating shaft, which is far away from the first shaft sleeve, is separated from the bracket to become a free end. The staff only need to remove the cutter wheel subassembly from the pivot to remove the pivot from this free end can.

It should be noted that, in order to facilitate the sleeve II being sleeved on the free end of the rotating shaft, the insertion end of the sleeve II for the rotating shaft to be inserted is a bell mouth structure.

It should be noted that if the cutter wheel assembly 280 is replaced integrally, the position of the cutter wheel assembly on the rotating shaft needs to be adjusted later, and this step is omitted. The cutter wheel assembly 280 includes a cutter seat 282 and a cutter wheel 281. The tool holder is slid on the rotating shaft 290, and a first bolt 283 is screwed on the side surface of the tool holder, and one end of the first bolt passes through the tool holder and then abuts against the surface of the rotating shaft so as to fix the tool holder. At least two webs 282a are provided in the shape of spokes on the rim of the tool holder, and through holes are formed in the webs.

The cutter wheel 281 is annular, and a avoiding groove 281a through which the web 282a can pass is formed in the cutter wheel. When the cutter wheel needs to be disassembled, the avoidance groove is aligned with the radial plate, so that the cutter wheel can conveniently pass through the cutter seat. When the fixed wheel is needed, the avoiding groove is misplaced with the radial plate, and then the cutter wheel is fixed on the cutter seat through a second bolt.

When maintenance is needed, the cutter wheel is only required to be detached from the cutter seat, and the cutter wheel is fixed on the cutter seat after being replaced again, so that the position is not required to be adjusted.

It should be noted that, in order to facilitate rotation of the second sleeve, a hand wheel 270 is coaxially disposed on an end surface of the second sleeve 260.

It should be further noted that, the carrying shaft mechanism 300 in this embodiment includes a carrying shaft 320, and one end of the carrying shaft rotatably penetrates through the frame and is connected to a motor two 320 in a driving manner. Meanwhile, the other end of the bearing shaft is rotatably arranged on the supporting seat 340, so as to ensure that the bearing shaft can stably rotate. It should be noted that the supporting seat is composed of a telescopic cylinder and two rotating wheels arranged at the end part of the telescopic cylinder, and one end of the object bearing shaft is erected on the two rotating wheels so as to ensure that the object bearing shaft is kept stable. In addition, it should be noted that two ends of the carrying shaft are respectively screwed with a limit baffle 330, and the two ends of the large roll of the adhesive tape are clamped by the limit baffles, so that the large roll of the adhesive tape is prevented from axial movement in the cutting process.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
