Furthermore, a ribbon shaft limiting hole 11 is provided on the support plate 1, and the ribbon shaft limiting hole 11 is provided along an axial direction perpendicular to the ribbon shaft. Optionally, the ribbon shaft limiting hole 11 is provided along Figure 1The carbon ribbon shaft extends in the longitudinal direction as shown, and the height of the carbon ribbon shaft is adjusted through the carbon ribbon shaft limiting hole 11. The carbon ribbon shaft adjustment assembly 2 includes an adjustment block 21, and the adjustment block 21 is connected to the carbon ribbon shaft on the other side of the support plate 1 through the carbon ribbon shaft limiting hole 11. The carbon ribbon shaft limiting hole 11 limits the moving direction of the adjustment block 21, and the position of the carbon ribbon shaft on the support plate 1 is adjusted by the adjustment block 21; at the same time, a lock limit hole 12 is set on the support plate 1, and the lock limit hole 12 extends in the same direction as the carbon ribbon shaft limiting hole 11. The lock adjustment assembly 3 includes a lock seat 31 and an adjustment code disk 32. The lock seat 31 is fixed by the lock limit hole 12, and the lock limit hole 12 is used to limit the moving direction of the lock seat 31. The adjustment code disk 32 is fixed by the lock limit hole 12. The seat 31 is connected to the support plate 1, and the adjusting code disk 32 adjusts the position of the lock seat 31 on the support plate 1. Specifically, the lock seat 31 is moved along the lock limit hole 12 by rotating the adjusting code disk 32, thereby changing the position of the lock seat 31 on the support plate 1, and then changing the position of the lock hook 37 connected to the lock seat 31. The lock 37 is used to connect the upper and lower parts of the thermal transfer device. The height-adjustable lock hook 37 is used to adjust the connection relationship between the upper and lower parts of the thermal transfer device. Under the action of the carbon ribbon shaft adjustment component 2 and the lock adjustment component 3, the carbon ribbon shaft and components such as the print head are always in a parallel state.

[0033] In another embodiment of the present application, the ribbon shaft adjustment assembly 2 includes two groups, which are respectively connected to the active ribbon shaft and the driven ribbon shaft to adjust their respective movements.

[0034] In one embodiment of the present application, the carbon ribbon shaft is connected to the support plate 1 through the carbon ribbon shaft base 13. Specifically, the carbon ribbon shaft fastening bolt 14 passes through the adjustment block 21 and the carbon ribbon shaft limiting hole 11 on the support plate 1 and is connected to the carbon ribbon shaft base 13 located on the other side of the support plate 1. The carbon ribbon shaft fastening bolt 14 can move in the carbon ribbon shaft limiting hole 11, thereby driving the carbon ribbon shaft base 13 to move, and finally achieving the purpose of adjusting the carbon ribbon shaft.

[0035] In one embodiment of the present application, the carbon ribbon shaft limiting hole 11 is along Figure 1 The longitudinal direction shown is extended so that the ribbon shaft fastening bolt 14 can move up and down to adjust the height of the ribbon shaft.

[0036] In one embodiment of the present application, the ribbon shaft adjustment assembly 2 also includes an adjustment plate 22 and an adjustment bolt 23. The adjustment plate 22 is fixed on the support plate 1. The adjustment bolt 23 connects the adjustment plate 22 and the adjustment block 21. The adjustment bolt 23 is used to adjust the height of the adjustment block 21. Specifically, the adjustment block 21 and the adjustment plate 22 are provided with matching connection holes 211 and connection holes 221. The axial directions of 211 and the connection holes 221 are arranged along the longitudinal direction. The adjustment bolt 23 passes through the connection holes 211 and the connection holes 221 to adjust the distance between the adjustment block 21 and the adjustment plate 22. Since the adjustment plate 22 is fixedly connected to the support plate 1, the adjustment bolt 23 can drive the adjustment block 21 to move up and down along the ribbon shaft limit hole 11.

[0037] Furthermore, the lock adjustment component 3 provided in the present application is provided with a code disk limiting hole 311, a lock connection piece 312 and a lock connection hole 313 on the lock seat 31, the lock connection piece 312 is connected to the support plate 1 through the lock connection hole 313 and the lock limiting hole 12, so as to fix the lock seat 31, the adjustment code disk 32 is connected to the lock seat 31 through the code disk limiting hole 311, the code disk limiting hole 311 is used to limit the movement of the adjustment code disk 32, and the carbon ribbon shaft limiting hole 11, the lock limiting hole 12 and the code disk limiting hole 311 extend in the same direction, that is, along Figure 1 Meanwhile, the adjusting code disk 32 is provided with a plurality of notches 33 in the circumferential direction, and when the adjusting code disk 32 rotates, the notches 33 can push the lock connector 312 , thereby driving the lock seat 31 to move along the lock limit hole 12 .

[0038] Figure 2 A three-dimensional diagram of a locking seat of a ribbon adjustment mechanism according to an embodiment of the present application is shown. Figure 3 A three-dimensional diagram of an adjustment code disk of a ribbon adjustment mechanism according to an embodiment of the present application is shown, combined with Figure 1-Figure 3 As shown, a code disc limiting hole 311 extending in the longitudinal direction is provided on the lock seat 31, and a code disc connecting hole 15 is provided on the support plate 1 corresponding to the code disc limiting hole 311, and an adjusting code disc fixing hole 321 is provided at the adjusting code disc 32 corresponding to the code disc limiting hole 311, and the connecting bolts successively pass through the adjusting code disc fixing hole 321, the code disc limiting hole 311 and the code disc connecting hole 15 to fix the adjusting code disc 32 and the lock seat 31 on the support plate 1, and since the adjusting code disc fixing hole 321 and the code disc connecting hole 15 are both round holes, it is ensured that the adjusting code disc 32 can only rotate on the support plate 1, and cannot move up and down or left and right. At the same time, since the code disc limiting hole 311 moves in the longitudinal direction, the lock seat 31 can move up and down relative to the adjusting code disc 32, thereby adjusting the height of the lock seat 31.

[0039] Furthermore, a plurality of snap-fitting parts 34 are provided on the adjustment code disk 32, and a plurality of snap-fitting positions 35 are provided on the lock seat 31. The snap-fitting positions 35 coincide with the center lines of the code disk limiting holes 311. After the snap-fitting parts 34 are docked with the snap-fitting positions 35, since the height of the adjustment code disk 32 remains unchanged, after different snap-fitting parts 34 are docked with the snap-fitting positions 35, the adjustment code disk 32 can push the lock seat 31 to move along the code disk limiting holes 311.

[0040] Figure 4 The schematic diagram of the assembly of the lock seat and the adjustment code disk of the ribbon adjustment mechanism of an embodiment of the present application is shown, wherein the adjustment code disk 32 is provided with three notches 33 to illustrate the situation where the adjustment code disk 32 pushes the lock seat 31 to move to three different heights, but other numbers of notches are also allowed by the present application. Figure 4 A. Figure 4 B and Figure 4 C shows the assembly status of the lock seat 31 at three different heights. Figure 4 A and Figure 4 As shown in C, two first clamping parts 341 are symmetrically arranged on the same side of the center line AA of the adjustment code disk 32, and the ends of the perpendicular midline of the central connecting line aa of the two first clamping parts 341 are respectively provided with a first notch 331 and a third notch 333, the first notch 331 corresponds to the first position, and the third notch 333 corresponds to the third position. Figure 4 As shown in B, two second clamping parts 342 are symmetrically arranged on the center line AA of the adjustment code disk 32, and a second notch 332 is arranged on the perpendicular midline of the center connecting line bb of the two second clamping parts 342, and the second notch 332 corresponds to the second position.

[0041] When the adjusting code disk 32 is rotated to the No. 1 position, at this time, the center line aa of the first clamping portion 341 is located below the center line AA of the adjusting code disk 32, and the first clamping portion 341 is clamped together with the clamping position 35 on the adjusting code disk 32, and the first notch 331 pushes the lock buckle connector 312 to move along the lock buckle limiting hole 12. Since the position of the clamping position 35 on the adjusting code disk 32 determines the position of the lock buckle seat 31, the lock buckle seat 31 is located at the lower position of the support plate 1 at this time; when the adjusting code disk 32 is rotated to the No. 2 position, at this time, the center line bb of the second clamping portion 342 coincides with the center line AA of the adjusting code disk 32, and the second clamping portion 342 is clamped together with the clamping position 35 hole on the adjusting code disk 32, and the second notch 332 pushes the lock buckle connector 312 to move along the lock buckle limiting hole 12. The connecting piece 312 moves along the lock limit hole 12. Since the position of the engaging position 35 on the adjusting code disk 32 determines the position of the lock seat 31, the lock seat 31 is located in the middle of the support plate 1 at this time; when the adjusting code disk 32 is rotated to the third position, the adjusting code disk 32 is rotated 180 degrees compared to the first position, and the center line aa of the first engaging portion 341 is located above the center line AA of the adjusting code disk 32. At the same time, the first engaging portion 341 is engaged with the engaging position 35 on the adjusting code disk 32, and the third notch 333 pushes the lock connecting piece 312 to move along the lock limit hole 12. Since the position of the engaging position 35 on the adjusting code disk 32 determines the position of the lock seat 31, the lock seat 31 is located at the upper position of the support plate 1 at this time.

[0042] In addition, a plurality of avoidance areas 36 are provided on the lock seat 31, and the avoidance areas 36 are used to accommodate the engaging portion 34 that is not matched with the engaging position 35. For example, when the first engaging portion 341 is engaged with the engaging position 35, the second engaging position 342 can be accommodated in the avoidance area 36, ​​thereby facilitating the assembly of the adjustment code disk 32 and the lock seat 31.

[0043] Furthermore, the lock adjustment assembly 3 also includes a lock hook 37, which is rotatably connected to the lock seat 31. When the lock seat 31 moves up and down, it can drive the lock hook 37 to move up and down, thereby achieving the purpose of adjusting the height of the entire carbon ribbon shaft.

[0044] The ribbon adjustment mechanism provided in the present application adjusts the position of the ribbon shaft and the lock by means of a ribbon shaft adjustment assembly and a lock adjustment assembly arranged on one side of the support plate. Specifically, the position of the adjustment block on the ribbon shaft adjustment assembly is limited by the ribbon shaft limiting hole set on the support plate, and the adjustment block is connected to the ribbon shaft, and then the ribbon shaft is driven to move by the adjustment block; the movement of the lock seat is limited by the lock limiting hole set on the support plate, and the lock seat is adjusted by adjusting the code disk to complete the movement of the lock seat. On the one hand, the ribbon shaft is adjusted by the ribbon limiting hole to solve the problem of the non-parallelism of the ribbon shaft caused by the error during the installation process; on the other hand, the position of the lock seat is adjusted by adjusting the code disk to solve the problem of non-adjustability when connecting the upper and lower parts of the thermal transfer machine by the lock, so as to facilitate the installer to adjust the connection position of the ribbon shaft and the upper and lower parts of the entire thermal transfer equipment during the assembly process, so as to avoid the problems of uneven ribbon or non-parallelism of the ribbon shaft and the print head caused by manufacturing or installation errors, thereby improving the printing quality and effectively avoiding the problems of unclear printing and ribbon smearing.

[0045] Furthermore, the present application provides a thermal transfer device, including the above-mentioned ribbon adjustment mechanism 10, and also including a ribbon shaft 20, the ribbon shaft 20 is connected to the ribbon shaft adjustment assembly 2, the ribbon adjustment mechanism 10 and the ribbon shaft 20 are located in the upper part of the entire thermal transfer device, and the upper part and the lower part are assembled by connecting the lock hook 37 and the lock rod 30. Its working principle is that in order to ensure the printing quality, it is necessary to ensure that the ribbon shaft 20 (including the active ribbon shaft and the passive ribbon shaft) and the printing rubber roller are in a parallel state with the print head. In this state, the ribbon will be evenly tightened without the problem of ribbon wrinkles, thereby avoiding problems such as unclear printing and ribbon smearing. During use, the height of the carbon ribbon shaft is adjusted by the carbon ribbon shaft adjustment component 2, and the height of the lock hook 37 is adjusted by the lock adjustment component 3, so that the carbon ribbon shaft 20, the printing rubber roller and the print head are always in a parallel state, thereby avoiding problems such as uneven carbon ribbon or non-parallelism between the carbon ribbon shaft and the print head caused by manufacturing or installation errors, thereby improving the printing quality and effectively avoiding problems such as unclear printing and carbon ribbon smearing.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
