Description

Technical Field

[0001] The invention relates to the field of thermal transfer printers, and in particular to a die-cutting module for a thermal transfer printer and a thermal transfer printer. Background Art

[0002] Thermal transfer printers are widely used in various industries due to their advantages such as fast printing speed and long shelf life of printed products. Existing thermal transfer printers already have a die-cutting function (the die-cutting function can cut printed materials or other paper products according to pre-designed patterns, so that the shape of the printed materials is no longer limited to straight edges and right angles). The die-cutting function is achieved by moving the die-cutting component in a first direction to cut the tape (through the die-cutting knife included in the die-cutting component) while cooperating with the bidirectional conveying component to clamp the conveying tape in a second direction (the first direction and the second direction are perpendicular to each other). The existing bidirectional conveying component generally includes a bidirectional conveying roller group and a tape pressing roller group. The bidirectional conveying roller group includes a conveying roller group and a conveying roller group. The die-cutting module comprises a roller and a first driving assembly, wherein the conveying roller is rotatably arranged on the frame of the die-cutting module along a first direction, and the first driving assembly is connected to the conveying roller in a driving manner so as to drive the conveying roller to rotate in both directions; the pressing tape roller assembly comprises a bracket, a swing rod, a pressing tape wheel, an adjusting cam and a second driving assembly, wherein the bracket is mounted on the above-mentioned frame, the swing rod is pivotally mounted on the bracket, the pressing tape wheel is rotatably arranged on one end of the swing rod along a first direction, the adjusting cam is pivotally mounted on the bracket, and the cam adjusting portion of the adjusting cam abuts against the other end of the swing rod so as to drive the swing rod to rotate in both directions by pivoting. The pressing position and the separating position are switched. In the pressing position, the pressing belt wheel is pressed on the conveying roller so as to clamp the conveying belt along the second direction; in the separating position, the pressing belt wheel is separated from the conveying roller, and the second driving component is connected to the adjusting cam in a transmission manner so as to drive the adjusting cam to rotate. The second driving component generally includes a DC motor, a transmission component (such as a synchronous belt and synchronous wheel component or a plurality of gears meshing with each other), a sensor and a controller. The sensor is electrically connected to the controller and is used to detect the position of the adjusting cam. When the adjusting cam reaches the desired position, the controller controls the DC motor to stop rotating, thereby making the adjusting cam stop at the desired position. Correspondingly, the rocker arm also stops at the pressing position or the separating position. However, in actual use, when the controller controls the DC motor to stop rotating, since the DC motor and the transmission component have a certain inertia during movement, the adjusting cam will still rotate a certain angle, thereby causing the rocker arm to be unable to accurately stop at the pressing position or the separating position. In addition, since the DC motor is frequently controlled by the controller to rotate forward and reverse, the current die-cutting module for thermal transfer printers also has the defect of being easily damaged. Summary of the invention

In the separation position, the pressure belt wheel is separated from the conveying roller, and the first direction, the second direction and the third direction are perpendicular to each other; a second driving assembly, the second driving assembly includes a crank rocker mechanism, a driving shaft and a second driving motor, the driving shaft is transmission-connected to the adjusting cam, and the second driving motor is transmission-connected to the driving shaft through the crank rocker mechanism; and a third driving assembly, the third driving assembly is transmission-connected to the die-cutting assembly so as to drive the die-cutting assembly along the first direction to cut the tape.

[0046] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0047] The present invention discloses a die-cutting module for a thermal transfer printer, specifically, Figures 1 to 6 As shown, the die-cutting module includes: a frame 1; a die-cutting component 2, which is slidably mounted on the frame 1 and is used to move along a first direction A to cut the tape (not shown in the figure); a bidirectional conveying roller group 4, which includes a conveying roller 41 and a first driving component 42, the conveying roller 41 is rotatably arranged on the frame 1 along the first direction A, and the first driving component 42 is connected to the conveying roller 41 in a driving manner so as to drive the conveying roller 41 to rotate bidirectionally; a tape pressing roller component 5, which includes a bracket 51, a swing rod 52, a tape pressing wheel 53 and an adjusting cam 54 (as shown in the figure); Figure 5As shown), the bracket 51 is installed on the frame 1, the middle part of the swing rod 52 is pivotally installed on the bracket 51, the pressing belt wheel 53 is rotatably arranged at one end of the swing rod 52 along the first direction A, the adjusting cam 54 is pivotally installed on the bracket 51, and the cam adjusting portion 541 of the adjusting cam 54 abuts against the other end of the swing rod 52 so as to drive the swing rod 52 to switch between the pressing position and the separation position by pivoting. In the pressing position, the pressing belt wheel 53 is pressed on the conveying roller 41 so as to clamp the conveying belt along the second direction B. In the separation position, the pressing belt wheel 53 is separated from the conveying roller 41, and the first direction A , the second direction B is perpendicular to the third direction C; a second driving assembly 6, the second driving assembly 6 includes a crank rocker mechanism 61, a driving shaft 62 and a second driving motor 63, the driving shaft 62 is connected to the adjusting cam 54, the second driving motor 63 is connected to the driving shaft 62 through the crank rocker mechanism 61, so as to drive the adjusting cam 54 to swing regularly between a first position and a second position (the first position and the second position of the adjusting cam 54 correspond to the pressing position and the separation position of the rocker rod 52 one by one); and a third driving assembly 7, the third driving assembly 7 is connected to the die-cutting assembly 2, so as to drive the die-cutting assembly 2 along the first direction A to cut the tape.

[0048] The die-cutting module for the thermal transfer printer of the present invention cleverly adopts a crank rocker mechanism 61 and a drive shaft 62 to connect the second drive motor 63 and the adjusting cam 54, thereby converting the rotational motion of the second drive motor 63 into a regular swinging motion of the adjusting cam 54. The swinging motion of the adjusting cam 54 corresponds to the pivoting motion of the rocker arm 52 between the pressing position and the separation position, thereby avoiding the defects of poor control accuracy and easy damage caused by the use of DC motors, transmission components (such as synchronous belt and synchronous wheel components or multiple gears meshing with each other), sensors and controllers in the prior art. It can be seen that the die-cutting module for the thermal transfer printer of the present invention has high control accuracy and reliability.

[0049] It should be noted that the specific structural forms or specific types of the frame 1, die-cutting assembly 2, bidirectional conveying roller group 4, adhesive tape roller assembly 5, second drive assembly 6, and third drive assembly 7 can be set as needed, which are all within the technical concept of the present invention. The specific embodiments of the above structure will be described below by way of example.

[0050] In the die-cutting module for the thermal transfer printer of the present invention, specifically, as Figure 1 , Figure 2 and Figure 6As shown, the frame 1 includes a first end plate 11, a second end plate 12, a connecting bracket 13 fastening the first end plate 11 and the second end plate 12, and a guide rail beam 14 fastening the first end plate 11 and the second end plate 12, the die-cutting assembly 2 is slidably mounted on the guide rail beam 14, and the bracket 51 is mounted at the bottom of the guide rail beam 14.

[0051] In the above die-cutting module, more specifically, Figure 3 and Figure 4 As shown, the die-cutting assembly 2 includes a slider 21, a plurality of rollers 22, a die-cutting knife 23, a guide assembly 24 and an electromagnet 25. The slider 21 is slidably mounted on the guide rail crossbeam 14 through the plurality of rollers 22. The die-cutting knife 23 is slidably mounted on the slider 21 along the third direction C through the guide assembly 24. The electromagnet 25 is used to drive the die-cutting knife 23 to move along the third direction C between a cutting position and a knife retracting position.

[0052] In the die-cutting module for the thermal transfer printer of the present invention, further specifically, as Figure 6 As shown, the die-cutting module also includes a die-cutting platform 8 which is fastened to the frame 1 and used to support the tape (the two sides of the die-cutting platform 8 are respectively fastened to the first end plate 11 and the second end plate 12), and the die-cutting platform 8 has a conveying gap, and a part of the conveying roller 41 protrudes from the conveying gap to above the die-cutting platform 8.

[0053] Existing thermal transfer printers already have a printing function (printing means using multiple different colored ribbons to print on the same piece of tape in sequence so that the tape displays multiple colors). During the printing process, the tape needs to be retracted to the starting position after printing one color of ribbon, and then the ribbon of another color is replaced on the thermal transfer printer, and then the printing of the other color ribbon continues from the starting position. In order to ensure that the colors of different ribbons are always accurately printed on the tape, it is necessary to ensure that the tape accurately returns to the starting position. During the tape retraction process of existing thermal transfer printers, there is a problem that the tape floats on the die-cutting platform of the die-cutting module, which causes the tape to be unable to accurately return to the starting position, resulting in the existing thermal transfer printer having a poor printing accuracy problem.

[0054] In order to solve the above technical problems and improve the printing accuracy of the thermal transfer printer, the die-cutting module for the thermal transfer printer of the present invention may also include a tape pressing plate 9 (such as a tape pressing plate 9) which is pivotally arranged on the frame 1 along the first direction A and located above the die-cutting platform 8. Figure 6As shown), one end of the tape pressing plate 9 close to the die-cutting assembly 2 abuts against the swing rod 52 so as to be driven by the swing rod 52 to switch between the open position and the tape pressing position. When the swing rod 52 is located at the separation position, the tape pressing plate 9 is located at the tape pressing position (when the swing rod 52 is located at the separation position, the thermal transfer printer of the present invention may be in a printing state including a stamping state. At this time, the tape pressing plate 9 is located at the tape pressing position. The tape pressing plate 9 can limit the tape on the die-cutting platform 8, thereby preventing the tape from floating on the die-cutting platform 8 of the die-cutting module, thereby improving the stamping accuracy of the thermal transfer printer of the present invention); when the swing rod 52 is located at the pressing position, the tape pressing plate 9 is located at the open position (when the swing rod 52 is located at the pressing position, the thermal transfer printer of the present invention may be in a die-cutting state. The tape pressing plate 9 can be located in the open position. At this time, the accuracy of die-cutting is not affected by the tape pressing plate 9).

[0055] In the above-mentioned die-cutting module, more preferably, the bidirectional conveying roller group 4 also includes an auxiliary conveying roller 43 rotatably arranged on the frame 1 along the first direction A, the pressure tape roller assembly 5 also includes an auxiliary pressure tape wheel 55 rotatably arranged on the pressure tape plate 9 along the first direction A, the first driving assembly 42 is also transmission-connected to the auxiliary conveying roller 43, the die-cutting platform 8 is provided with an opening, a part of the auxiliary conveying roller 43 protrudes from the opening to above the die-cutting platform 8, when the pressure tape plate 9 is located in the open position, the auxiliary pressure tape wheel 55 is separated from the auxiliary conveying roller 43; when the pressure tape plate 9 is located in the pressure tape position, the auxiliary pressure tape wheel 55 is pressed on the auxiliary conveying roller 43, so that when the thermal transfer printer of the present invention is in the overprinting state, the auxiliary conveying roller 43 and the auxiliary pressure tape wheel 55 can assist in clamping the conveying tape.

[0056] In the die-cutting module for the thermal transfer printer of the present invention, specifically, the die-cutting module includes a plurality of the pressure tape roller assemblies 5 arranged side by side and spaced from each other, and the drive shaft 62 is in turn transmission connected to the respective adjustment cams 54 of the plurality of pressure tape roller assemblies 5; the third drive assembly 7 includes a third drive motor 71 and a synchronous belt and synchronous wheel assembly 72 transmission connected to the third drive motor 71, and the synchronous belt in the synchronous belt and synchronous wheel assembly 72 is transmission connected to the die-cutting assembly 2.

[0057] In addition, the present invention also provides a thermal transfer printer, specifically as follows Figure 7 As shown, the thermal transfer printer includes the die-cutting module 10 for the thermal transfer printer described in the present invention.

[0058] Since the thermal transfer printer of the present invention includes the die-cutting module for the thermal transfer printer of the present invention, it also has the above advantages of the die-cutting module.

However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0060] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
