[0042] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0043] Example 1

[0044] like Figure 1-Figure 6 As shown, a tape roll installation assembly 43 of the present embodiment includes a mounting shaft 431, a limiting sleeve 438 and two tape roll chucks 436, one end of the mounting shaft 431 is connected to the driving assembly 44, and a limiting clamping portion adapted to be clamped with the tape roll chuck 436 is provided near one end of the mounting shaft 431, and the limiting clamping portion is used to limit and adapt a tape roll chuck 436 inserted from the other end of the mounting shaft 431, and the limiting sleeve 438 is sleeved from the other end of the mounting shaft 431 and fixed on the mounting shaft 431 and limits the other tape roll chuck 436 on the mounting shaft 431 and the tape roll 7. The tape roll chuck 436 can be assembled on the installation shaft 431, and then the tape roll 7 can be installed between the two tape roll chucks 436. The limiting clamping part clamps one of the tape roll chucks 436 and limits the other tape roll chuck 436. When assembling, the tape roll chuck 436 and the tape roll 7 can be directly inserted into the installation shaft 431 for clamping and limiting. When disassembling, the limiting sleeve 438 can be removed directly from the other end of the installation shaft 431, which is convenient for disassembly. The tape roll 7 is limited by the tape roll chuck 436, which is convenient for the subsequent stable and orderly release of the tape. The limiting sleeve 438 is detachably arranged on the outer periphery of the second transmission shaft 433 so as to abut and limit the other tape roll chuck 436 to prevent the tape roll 7 and the two tape roll chucks 436 from moving axially.

[0045] The diameter of the center hole of the tape roll chuck 436 is equal to the diameter of the mounting shaft 431, so that the tape roll 7 and the tape roll chuck 436 can be inserted into the mounting shaft 431. The position-limiting clamping portion includes a position-limiting flange and a clamping tooth or a clamping groove arranged on the end surface of the position-limiting flange, and the clamping tooth or the clamping groove is used to be adapted and clamped with a corresponding groove or protrusion on the tape roll chuck 436.

[0046] like Figure 2-Figure 4 As shown, one end of the installation shaft 431 of this embodiment is detachably connected to the first transmission shaft 432, one end of the first transmission shaft 432 is adapted to be inserted and fixed in one end of the installation shaft 431, and the limit clamping portion is integrally arranged on the first transmission shaft 432 or integrally arranged on the installation shaft 431. The free end of the first transmission shaft 432 is connected to the driving assembly 44, and the arrangement of the first transmission shaft facilitates the arrangement of the limit clamping portion and other components, and also facilitates molding and installation.

[0047] like Figure 2-Figure 4 As shown, the tape roll installation assembly 43 of this embodiment further includes a second transmission shaft 433, which is fixed to the other end of the installation shaft 431, and a shaft sleeve 435 is installed on the second transmission shaft 433. The provision of the second transmission shaft is conducive to the assembly of the installation shaft.

[0048] Among them, Figure 7-Figure 9 As shown, the first transmission shaft 432 and the second transmission shaft 433 at both ends of the tape roll installation assembly 43 are rotatably inserted into the U-shaped installation grooves of the first installation plate 41 and the second installation plate 42 respectively through the shaft sleeve 435, and the driving assembly 44 is fixed on the first installation plate 41 and is connected to the tape roll installation assembly 43 in transmission.

[0049] like Figure 2-Figure 6 As shown, one end of the mounting shaft 431 of this embodiment is connected to a transmission clutch 434, and the driving assembly 44 is in transmission connection with the transmission clutch 434; and / or, it also includes a laminating mechanism 8, which is installed on the frame 1 and located between the printing mechanism 3 and the tape retracting mechanism 4. The setting of the transmission clutch avoids problems in the reeling and unreeling of the tape due to too fast or too slow rotation speed. The laminating module is used to receive the tape that has undergone the thermal transfer printing process in the printing module and then attach a protective film to the surface of the tape.

[0050] like Figure 2-Figure 6 As shown, the transmission clutch 434 of this embodiment is installed at the other end of the first transmission shaft 432, and the driving assembly 44 is in transmission connection with the transmission clutch 434. The transmission clutch 434 is arranged at the free end of the first transmission shaft 432, and when the two ends of the tape roll installation assembly 43 are rotatably inserted in the respective U-shaped installation grooves of the first installation plate 41 and the second installation plate 42, the transmission clutch 434 is in transmission connection with the driving assembly 44, so that the driving assembly 44 drives the tape roll installation assembly 43 to rotate so that the tape roll 7 rotates to release or rewind the tape, and when the driving speed of the driving assembly 44 is greater than the speed of releasing the tape or the speed of rewinding the tape, the transmission clutch 434 is arranged to disconnect the transmission connection between the driving assembly 44 and the first transmission shaft 432.

[0051] like Figure 5 and Figure 6As shown, the transmission clutch 434 of this embodiment includes a transmission sleeve shaft 4341, a friction plate 4342, a transmission gear 4343, a one-way bearing 4344, a limiter 4345 and a spring 4346. A flange is formed at one end of the transmission sleeve shaft 4341, and the friction plate 4342, the transmission gear 4343 and the spring 4346 are sequentially put onto the transmission sleeve shaft 4341 from the other end of the transmission sleeve shaft 4341, and the limiter 4345 is clamped on the other end of the transmission sleeve shaft 4341 to limit the spring 4346 on the transmission sleeve shaft 4341; the other end of the transmission sleeve shaft 4341 is put on the outer side of the free end of the first transmission shaft 432 and is rotatably connected to the first transmission shaft 432 through the one-way bearing 4344; the transmission gear 4343 is transmission-connected to the drive assembly 44. Specifically, when both ends of the tape roll mounting assembly 43 are rotatably inserted into the U-shaped mounting grooves of the first mounting plate 41 and the second mounting plate 42, the transmission gear 4343 is transmission-connected with the driving assembly 44. The friction disc 4342 can be a felt disc.

[0052] When the driving speed of the driving component 44 is greater than the speed of releasing the tape or the speed of winding the tape, slippage occurs between the end face of the transmission gear 4343 and the end face of the friction plate 4342, thereby disconnecting the transmission connection between the driving component 44 and the first transmission shaft 432; when the driving speed of the driving component 44 is less than or equal to the speed of releasing the tape or the speed of winding the tape, the end face of the transmission gear 4343 and the end face of the friction plate 4342 frictionally transmit torque, thereby realizing the transmission connection between the driving component 44 and the first transmission shaft 432.

[0053] A preferred solution of this embodiment is as follows: Figure 5 As shown, the transmission clutch 434 also includes a plastic gasket 4347 disposed between the limiter 4345 and the spring 4346 to eliminate friction and noise between metal parts.

[0054] like Figure 8 and Fig. 9As shown, the driving assembly 44 includes a motor 441, a reducer 442 and a mounting frame 443, the mounting frame 443 is fixed on the first mounting plate 41, and the reducer 442 and the motor 441 are fixed on the mounting frame 443.

[0055] When the tape roll 7 needs to be replaced, first remove the tape roll installation assembly 43 (together with the tape roll 7 installed therein) from the U-shaped installation grooves of the first installation plate 41 and the second installation plate 42, and then remove the limit sleeve 438 from the second transmission shaft 433. Then, since the diameter of the assembly shaft 431 is greater than or equal to the diameter of the first transmission shaft 432 and the diameter of the second transmission shaft 433, the tape roll 7 together with the two tape roll chucks 436 can be removed from one side of the second transmission shaft 433. Finally, remove the tape roll chucks 436 from both ends of the tape roll 7 and install the tape roll chucks 436 on the required tape roll 7. Repeat the above steps to complete the replacement of the tape roll 7.

[0058] The diameter of the center hole of the tape roll chuck 436 is equal to the diameter of the mounting shaft 431, so that the tape roll 7 and the tape roll chuck 436 can be inserted into the mounting shaft 431. The position-limiting clamping portion includes a position-limiting flange and a clamping tooth or a clamping groove arranged on the end surface of the position-limiting flange, and the clamping tooth or the clamping groove is used to be adapted and clamped with a corresponding groove or protrusion on the tape roll chuck 436.
