[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 2 The label die-cutting device cutting head of this embodiment includes a base plate 1 and a cutting blade 3 disposed on its front side. Two upright plates 5 are disposed on the front side of the base plate 1 and near its left and right ends. A fixing mechanism 4 for fixing the upright plates 5 is disposed on the front side of the base plate 1. A square column 6 and a rotating roller 7 are disposed on the front side of the base plate 1. Two motors 8 are fixed on the right side of the right upright plate 5. An adjustment mechanism 2 is disposed on the outside of the cutting blade 3. A positioning column for horizontal sliding of the two upright plates 5 is fixed on the front side of the base plate 1.

[0022] Square blocks are fixed to the left ends of both the square column 6 and the rotating roller 7. Two bearing seats are installed on the left side of the left vertical plate 5. Square grooves for the two square blocks to fit together are opened on the left side of both bearing seats. The square column 6 and the rotating roller 7 are fixed to the left side of the right vertical plate 5 and are respectively fixedly connected to the output shafts of the two motors 8. The cutting blade 3 slides horizontally on the outside of the square column 6.

[0023] Understandable,

[0024] Please see Figure 3 In this embodiment, the adjustment mechanism 2 includes two connecting plates 201 fixed to the left and right sides of the cutting blade 3. A cylinder 202 is fixed to the opposite side of each of the two connecting plates 201. A positioning block 203 is fixed to the back wall of the inner cavity of each of the two cylinders 202. A positioning plate 204 is fixed to the opposite side of each of the two connecting plates 201. A limit plate 205 is fixed to the front side of each of the two positioning plates 204. Two springs 206 are fixed to the front side wall of the inner cavity of each of the two cylinders 202. A movable plate 207 is fixed to the back side of each of the two springs 206. Movable columns 208 are rotatably connected to the inside of each of the two movable plates 207 through bearings. A locking block 209 is fixed to the upper surface of each of the two movable columns 208 and near its back side.

[0025] Two springs 206 are respectively fitted onto the outer sides of two movable columns 208. Each movable column 208 has a handle fixed to its front end. The upper surfaces of the two limiting plates 205 are provided with slots for placing two locking blocks 209. By pulling the two adjacent handles, they are pulled forward and deflected towards one side of the slot. When the locking block 209 is inserted into the slot, the cutting head can be pushed to slide horizontally on the outer side of the square column 6, thereby adjusting the position of the cutting head. The front side of the square column 6 has multiple fixing holes for the movable column 208 to engage. The cutting head can be fixed by re-engaging the movable column 208 into the fixing holes. The front and rear ends of the square column 6 are respectively fitted with the positioning block 203 and the positioning plate 204. When the motor 8 controlling the square column 6 drives its output shaft, the movable column 208 will not be disengaged from the fixing holes. Another motor 8 is started to make the rotating roller 7 rotate in the opposite direction to the square column 6. At this time, the label to be cut is placed on the connecting column between the rotating roller 7 and the cutting blade 3 for precise cutting.

[0026] It is understood that the working principle of the precise cutting of the label in this application is the same as that of patent CN212919550U, and this application will not elaborate further.

[0027] Please see Figure 4 In this embodiment, the fixing mechanism 4 includes four connecting rod buckles 401 fixed to the upper surface of the base plate 1. Each of the four connecting rod buckles 401 is rotatably connected to a pull ring 402. The upper and lower ends of the two upright plates 5 are fixed with bases 403.

[0028] Four bases 403 are respectively set on one side near the base plate 1, and four pull rings 402 are respectively snapped and sleeved on the outside of the four bases 403. When it is necessary to disassemble the cutting blade 3, simply detach the pull rings 402 on the left and right sides from their bases 403, and the two upright plates 5 can be lifted upward. At this time, the left upright plate 5 can be pulled to the left to detach from the square column 6 and the rotating roller 7, and the cutting blade 3 located outside the square column 6 can be slid to the left to disassemble, so as to facilitate the disassembly of the cutting head of the label die-cutting device.

[0029] Understandably, by pulling the two adjacent handles forward and deflecting them toward one side of the slot, once the locking block 209 is inserted into the slot, the cutting head can be pushed to slide horizontally on the outside of the square column 6, thus facilitating the adjustment of the cutting head's position. This solves the problem that fixing the cutting blade 3 is cumbersome and requires tightening or loosening bolts, resulting in a complicated adjustment method.

[0030] All electrical components mentioned in this article are electrically connected to the main controller and power supply, and all electrical components mentioned are conventional and known devices. This application will not elaborate further. The main controller can be a conventional and known device such as a computer that performs control. The control circuit of the main controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so this utility model will not explain the control method and circuit connection in detail. At the same time, any parts of this utility model that are not described in detail are all common technologies known to those skilled in the art.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The working principle of the above embodiments is as follows:

[0033] When the label die-cutting head needs to be used, pull the two adjacent handles to pull it forward and deflect it toward one side of the slot. When the locking block 209 is inserted into the slot, the cutting head can be pushed to slide horizontally on the outside of the square column 6, thereby adjusting the position of the cutting head. After adjustment, the movable column 208 can be re-engaged into the fixing hole to fix the cutting head. When the motor 8 controlling the square column 6 drives its output shaft, the movable column 208 will not be dislodged from the fixing hole. Start another motor 8 to make the rotating roller 7 rotate in the opposite direction to the square column 6. At this time, place the label to be cut on the connecting column between the rotating roller 7 and the cutting blade 3 for precise cutting. When the cutting blade 3 needs to be disassembled, simply remove the pull rings 402 on the left and right sides from their bases 403 to lift the two upright plates 5 upward. At this time, the left upright plate 5 can be pulled to the left to disassemble the square column 6 and the rotating roller 7, and the cutting blade 3 located on the outside of the square column 6 can be slid to the left to be disassembled, thus facilitating the disassembly of the label die-cutting head.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
