Description
Technical Field
[0001] This utility model mainly relates to the field of printers, specifically to a tape cutting device for a thermal transfer printer. Background Technology
[0002] Thermal transfer printing heats a ribbon with a thermal printhead, melting the ink onto the label material to form a pattern. The ribbon material is absorbed by the medium, and the pattern becomes part of the label, providing pattern quality and durability unmatched by other on-demand printing technologies. Compared to thermal printing, thermal transfer printing accepts a wider variety of media, including paper, polyester, and polypropylene materials, and the printed text lasts longer.
[0003] In the invention patent application CN201922005160.6, published on September 11, 2020, entitled "Tape Cutting Device and Thermal Transfer Printer for Thermal Transfer Printers", a frame assembly is included. The frame assembly is provided with tape passing grooves distributed along a first direction A. A movable cutter assembly is also included. The movable cutter assembly includes a slider and a disc cutter rotatably mounted on the slider. The slider is slidably mounted on the frame assembly along the first direction A and is located on one side of the tape passing groove along a second direction B. This device effectively prevents the tape from sticking to the aforementioned components by providing a first anti-stick coating on the outer surface of the disc cutter, the outer surface of the fixed cutter, and the groove surface of the tape passing groove.
[0004] However, in actual use, this paper feeding assembly is difficult to repair or replace when the fixed cutter part malfunctions or is damaged after long-term use. Utility Model Content

[0009] Furthermore, this device is installed inside the thermal transfer printer via an internal fixing plate. The extension frame is provided with a movable slot, and the surface of the movable slot is provided with a support slot for the movement of the paper cutter. The scraper is provided on the lower end surface of the support slot. The drive block forms a moving structure through the rotation of the transmission belt, and the paper cutter forms a sliding structure on the surface of the support slot through the drive block.
[0010] Furthermore, the drive block includes a traction insert, the surface of which is provided with an insert groove, the surface of which is provided with a cut semicircular block, a spring hole on one side of which is provided with a support spring, and a pull rod is sleeved and connected to the support spring on one side of the cut semicircular block.
[0011] Furthermore, the cut semicircular block and the pull rod form an elastic structure on the surface of the spring hole and the insert slot through the support spring, and the traction insert is moved by the transmission belt.
[0012] Furthermore, the paper cutter includes a fitting block, a crank connecting block is fixedly connected to one side surface of the fitting block, a blade rubber clamping block is provided below the other end surface of the crank connecting block, a sliding wheel is provided on one side surface of the blade rubber clamping block, a blade mounting groove is provided on the lower end surface of the blade rubber clamping block, and a cutting blade is mounted on the surface of the blade mounting groove.

The cutting blade and the blade rubber clamp form a sliding structure on the surface of the support groove through the traction insert.
[0014] 3. Beneficial effects:
[0015] This utility model is reasonably designed. During tape cutting, starting the transmission motor drives the transmission gear and drive gear to rotate, which in turn drives the transmission pulley to rotate. Simultaneously, the transmission belt on the surface of the transmission pulley rotates, causing the drive block on the inner surface of the transmission belt to move. This, in turn, moves the crank connecting block, the blade rubber clamp, and the cutting blade at one end of the drive block along the support groove surface, thus performing the tape cutting operation inside the thermal transfer printer.
[0016] When the cutting blade in the paper cutter needs to be replaced or repaired, pull the pull rod at the upper and lower ends of the traction block to pull the two semi-circular cutting blocks back into the spring holes, push the fitting block out of the insertion block slot, and quickly disassemble the paper cutter. At the same time, when installing, place the fitting block on the surface of the support slot and push the fitting block into the traction block to complete the quick installation.

A drive belt 8 is sleeved between the drive pulleys 7, and a drive block 9 is disposed on the inner surface of the drive belt 8. The extension frame 2... A paper cutter 10 is slidably connected to the surface of the extension frame 2. A scraper 11 is provided at the lower end of the extension frame 2. The device is installed inside the thermal transfer printer via an inner fixing plate 1. A movable slot is provided on the surface of the extension frame 2, and a support slot for the movement of the paper cutter 10 is provided on the surface of the movable slot. The scraper 11 is provided on the lower end surface of the support slot. The drive block 9 forms a moving structure through the rotation of the transmission belt 8, and the paper cutter 10 forms a sliding structure on the surface of the support slot through the drive block 9. The device can be quickly disassembled and repaired by the drive block 9 and the locking block 1001 in the paper cutter 10.

The locking block 1001 is a locking block with a round head at one end and a square head at the other end. The blade rubber clamping block 1003 is connected to the surface of the traction insert 901 by the locking block 1001. The cutting blade 1006 is mounted on the surface of the blade mounting groove 1005 by a mounting screw. The cutting blade 1006 and the blade rubber clamping block 1003 form a sliding structure on the surface of the support groove through the traction insert 901.
[0031] In this embodiment, when the cutting blade 1006 in the paper cutter 10 needs to be replaced or repaired, the pull rod 906 at the upper and lower ends of the traction insert 901 is pulled, the two semi-circular cutting blocks 903 are pulled back into the spring hole 904, and the fitting block 1001 is pushed out from the insert slot 902, so that the paper cutter 10 can be quickly disassembled. At the same time, when installing, the fitting block 1001 is placed on the surface of the support slot, and the fitting block 1001 is pushed into the traction insert 901 to complete the quick installation.
