It is set to the side far from consumptive material mounting assembly 2 in casing 1, motor 51 is set in casing 1, is arranged between two conveying rollers 52
There are belt 1, arbitrary conveying roller 52 to be sequentially connected by belt 2 511 and motor 51.
As shown in Figures 2 and 4, print head 53 is located at the top of conveying roller 52 (referring to Fig. 3) and by 1 turn of shaft 12 and casing
Dynamic connection；Opposing sidewalls in casing 1 are simultaneously fixedly installed mounting rod 2 13 positioned at the left and right sides of print head 53 and keep out bar
2 14, mounting rod 2 13 and keep out the left side that bar 2 14 is respectively positioned on shaft 12；It is arranged with torsional spring 2 131 on mounting rod 2 13, turns round
One end of spring 2 131 is fixedly connected with bar 2 14 is kept out, and the downside of the other end and print head 53 contradicts.It is also set up in casing 1
It is useful for the fixed mechanism 6 that limitation print head 53 rotates, when the downside of print head 53 and the conflict of conveying roller 52, torsional spring 2 131
One end be pressed down against by print head 53, fixed mechanism 6 fixes print head 53 at this time.
As shown in figure 4, the fixed mechanism 6 includes clamping block 61 and clamping bar 62.Clamping block 61 includes swing part 611 and determines
Position portion 612, swing part 611 are integrally formed with positioning region 612, and coupling part between the two is in arc transition and downward concave shape
At there is circular arc guide part 613；Clamping bar 62 is fixedly installed on the both sides of print head 53, is offered on positioning region 612 and clamping
The clamping notch 6121 that bar 62 is adapted to.When print heads rotatable 53, clamping notch 6121 is located on the rotation path of clamping bar 62.
As shown in figure 4, the opposing sidewalls in casing 1 are rotatably connected to mounting rod 1, one end of mounting rod 1 is worn
Enter 1 inside of casing and be arranged with torsional spring 1, other end swing part 611 is fixed；One end of casing 1 is penetrated in mounting rod 1
It is provided with the driving lever 152 of its vertical length direction, while being further fixedly arranged on inside casing 1 and keeping out bar 1, torsional spring 1
One end and keep out the fixation of bar 1, the downside of the other end and driving lever 152 contradicts.
As shown in Fig. 2, being provided with ribbon guide bar 18 in side of the print head 53 far from shaft 12.It is printed in equipment
When colour band is passed through from ribbon guide bar 18, ribbon guide bar 18 can play the role of guiding and tensioning, so that color
Band is not easy the free bend in print procedure and influences printing effect.
Specific implementation process：The printing paper printed will be needed to be installed in consumptive material mounting assembly 2, and be oriented to successively from consumptive material
17 downside of bar, 52 upside of conveying roller and 53 downside of print head are pierced by, while installing colour band makes it be contacted with the surface of printing paper.
Print head 53 is rotated down after installation is complete, one end that torsional spring 2 131 is contradicted with print head 53 is pressed down against, when clamping bar
62 continue to rotate down print head 53 when contradicting with clamping block 61, and one end of torsional spring 1 can downwards be squeezed by driving lever 152 at this time
Pressure, clamping bar 62 can be slided in clamping notch 6121 and be blocked along circular arc guide part 613, pass through clamping notch 6121 and clamping
The position of fixing printing head 53 is capable of in the cooperation of bar 62, so that print components 5 are not easy in printing because teetertottering due to shadow
Ring print quality.When needing to lift print head 53, it need to only be pressed down against the swing part 611 of clamping block 61, positioning region 612 can be to
Lower movement, clamping bar 62 will take advantage of a situation and be detached from out of clamping notch 6121, and torsional spring 1 and torsional spring 2 131 are extruded at this time
One end can be such that print head 53 bounces automatically because restoring elastic deformation, while clamping block 61 can also restore to its original state.
Embodiment 2：A kind of wide cut thermal transfer printer, as shown in figure 5, difference from example 1 is that, this is fixed
Mechanism 6 includes two caging bolts 63, and two caging bolts 63 are threadedly connected to the opposite two side in casing 1 respectively.When
Print head 53 turns to when being contradicted with conveying roller 52 (referring to Fig. 2), the upside of the downside and print head 53 of two caging bolts 63
It contradicts.
Specific implementation process：When needing print heads rotatable 53, first caging bolt 63 is screwed in casing 1, works as print head
53 again back-out caging bolt 63 when being contradicted with conveying roller 52 so that the bottom of caging bolt 63 contradicts print head 53, to make
Obtaining print head 53 will not teetertotter in printing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
