As shown in FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 , and FIG. 5 , the printing apparatus 1 having an adjustment mechanism in the present invention includes a base 2 , at least one nozzle 3 , and an adjustment mechanism 4 , wherein the adjustment unit has an adjustment. The printing device 1 of the mechanism is, for example but not limited to, an inkjet printer or a multifunction printer, and the base 2 has a first side 21 and a second side 22 opposite to each other. The nozzle 3 has a first end portion 31 and a second end portion 32. The first end portion 31 is rotatably disposed on the first side edge 21 of the base 2, and the second end portion 32 is movably disposed on the base portion. The second side 22 of the second side 32 has a slope P.

According to the concept of the present invention, the adjustment mechanism 4 includes a limiting element 41 and at least one adjustment component 42. The limiting component 41 is disposed on the second side 22 of the base 2, and the adjusting component 42 is threaded and fixed to the limiting component 41, and is perpendicularly pushed against the inclined surface P of the second end 32 of the nozzle 3, The adjustment head 3 is moved relative to the base 2. In some embodiments, the second end portion 32 of the nozzle 3 has a slider, and the slope P is present in the slider, so that the adjustment assembly 42 can push the nozzle 3 and push the nozzle 3 to adjust the nozzle 3 Moving relative to the base 2, but not limited thereto.

In some embodiments, the adjustment component 42 is movably disposed in the first direction d1 to the limiting element 41, and the second end 32 of the nozzle 3 is movably disposed in the second direction d2. The two sides 22, wherein the first direction d1 is perpendicular to the slope P, and the second direction d2 is parallel to the second side 22, which are not limited thereto.

According to the concept of the present invention, the first side 21 of the base 2 has at least one raised portion 210, and the first end portion 31 of the shower head 3 has a hole 310, wherein the raised portion 210 is disposed corresponding to the hole 310, and The raised portion 210 is disposed through the hole 310 such that the raised portion 210 becomes a pivotal fulcrum of the head 3 such that the first end portion 31 of the head 3 is rotatably disposed on the first side 21 of the base 2. In some embodiments, after the adjustment of the nozzle 3, the first end portion 31 is fixed to the base 2 through the elastic fixing member 5, and the elastic fixing member 5 is adjacent to the boss portion 210, wherein the elastic fixing member 5 is disposed. It may be, for example, but not limited to, a shrapnel, or a combination of a screw 51 and a spring 52 to avoid slight errors in the nozzle 3 when it is locked.

In some embodiments, the adjustment assembly 42 includes a screw 421 and a spring 422, wherein the screw 421 of the adjustment assembly 42 can also be replaced with any linearly movable adjustment element such as, but not limited to, a screw or cam. The screw 421 is inserted through the spring 422 and is passed through and fixed to the limiting member 41. This prevents the screw 421 from loosening, and the structure is simple and the cost is relatively low.

In some embodiments, the relationship between the amount of rotation of the screw 421 and the amount of rotation of the head 3 is related to the screw pitch and the angle of the bevel. For example, if the screw pitch is 0.5 mm and the bevel angle is 55°, the second end 32 of the nozzle 3 can be moved by about 0.61 mm in the second direction d2 when the screw 421 is rotated once, which is the distance from the nozzle 3 When the rotating shaft is 98.45 mm, the rotation amount of the head 3 can be found to be about 0.35°. Moreover, since the rotation of the screw 421 is a segmentless type, there is no minimum adjustment amount. For example, when the screw 421 is rotated about 1/8 of a turn, the rotation amount of the nozzle 3 is only about 0.044°, whereby the adjustment assembly 42 can finely face the nozzle. 3 Make adjustments.

In other words, the printing device with the adjusting mechanism of the present invention can adjust the movement of the nozzle relative to the base by setting the adjusting mechanism in the printing device, and reduce the manufacturing cost and the required precision of the printing device, and reduce the processing factors of the parts. The impact on image quality. And through the first end of the nozzle The portion is rotatably disposed on one side of the base, the second end of the nozzle is movably disposed on the other side of the base, and the adjusting assembly is pushed against the inclined surface of the second end to independently adjust each of the printing heads Skew and deviation.

Please refer to FIG. 1 , FIG. 3 , FIG. 4 and FIG. 6 , wherein FIG. 6 is a schematic diagram showing the mechanical analysis of the printing device with the adjusting mechanism according to the preferred embodiment of the present invention. As shown in FIG. 1 , FIG. 3 , FIG. 4 , and FIG. 6 , in some embodiments, the adjustment mechanism 4 may further have an elastic member 43 disposed on the second side 22 of the base 2 . The second end portion 32 of the nozzle 3 is pressed and pressed, but not limited thereto.

In some embodiments, the elastic member 43 further includes a body portion 431, at least one pressing portion 432, and at least one abutting top portion 433, wherein the pressing portion 432 and the abutting top portion 433 are correspondingly disposed at the second end portion 32 of the head 3. The body portion 431 is fixed to the second side 22 of the base 2, the pressing portion 432 is extended by the body portion 431, and the pressing portion 432 is parallel to the second side 22 to press the second end portion 32. The abutting top 433 is extended from the body portion 431 and the abutting top 433 is perpendicular to the second side 22 to abut the second end 32.

For example, when the adjustment assembly 42 moves in a first direction d1 perpendicular to the slope P, the second end 32 of the head 3 moves along a second direction d2 parallel to the second side 22, but due to the second end The portion 32 is pressed by the pressing portion 432 so that the head 3 does not cause a displacement error perpendicular to the second side 22 as a result. Further, since the second end portion 32 of the head 3 is abutted against the top portion 433, the head 3 is not largely moved by the adjustment. Therefore, the head 3 can be finely adjusted to move relative to the base 2. Similarly, when the adjustment assembly 42 moves in the opposite direction of the first direction d1, the second end portion 32 of the head 3 is pushed against the top portion 433 and moved in the opposite direction in the second direction d2.

That is, if the printing apparatus 1 having the adjusting mechanism of the foregoing embodiment is subjected to mechanical analysis, it can be seen that the adjusting unit 42 has a positive force A and a positive force A for the inclined surface P of the second end portion 32. Further, it may be a component B parallel to the second direction d2 and a component C perpendicular to the second direction d2, wherein the component C is balanced with the support force D of the susceptor 2, and the component B is coupled with the elastic component. 43 is at equilibrium with the pressure E provided by the top 433 opposite to the second direction d2. In some embodiments, the pressure E can also be provided by providing a tension spring, but not limited thereto.

When the adjustment assembly 42 is moved in the first direction d1, the component B is greater than the pressure E, so that the second end 32 is moved in the second direction d2. Conversely, when the adjustment assembly 42 moves in the reverse direction of the first direction d1, the pressure E is greater than the component B, and the second end 32 is pushed against the top 433 and moved in the opposite direction of the second direction d2. Thereby, the effect of moving the head to the left and right to finely adjust the horizontal angle of the head can be achieved.

According to the concept of the present case, the limiting member 41 can be sleeved on the elastic member 43 to stabilize the elastic member 43 and prevent the elastic member 43 from being bent by adjusting the nozzle 3. In some embodiments, the limiting component 41 further has at least one connecting portion 410, a first body 411 and a second body 412, and the connecting portion 410 is perpendicular to and connects the first body 411 and the second body 412, and the adjusting component 42 It is worn and fixed to the connecting portion 410, but is not limited thereto.

In some embodiments, the limiting element 41 can have a coarse adjustment hole 413, wherein the coarse adjustment hole 413 is, for example but not limited to, an elliptical hole. The locking element 414 is threaded through the coarse adjustment hole 413 and fixed to the base 2, and the adjustment elastic element 43 is moved relative to the base 2.

For example, the printing device 1 having the adjusting mechanism of the present invention may include a base 2, a plurality of nozzles 3 and an adjusting mechanism 4, wherein the adjusting mechanism 4 includes a limiting member 41, a plurality of adjusting members 42 and an elastic member 43. And the number of adjustment components 42 is equal to the number of the nozzles 3. In addition, the detailed features of the foregoing components have been described in detail above, and thus will not be described again. Since the locking component 414 is movably disposed in the coarse adjustment hole 413 of the limiting component 41, and can be configured as a multi-segment or a non-segmental movement, The positional element 41 is movable in the second direction d2 to adjust the movement of the elastic element 43 relative to the base 2, so that the elastic element 43 abutting against the second end 32 drives the plurality of nozzles 3 to move relative to the base 2, The plurality of nozzles 3 are adjusted integrally and roughly. By finely and roughly adjusting the nozzle 3 through the adjustment mechanism 4, the precision of the adjustment can be improved, thereby improving the printing quality.

In summary, the present invention provides a printing device having an adjustment mechanism that solves and improves the problems and disadvantages of the prior art described above, and adjusts the movement of the nozzle relative to the base by providing an adjustment mechanism in the printing device, and Reduce the manufacturing cost and required precision of the printing device, and reduce the influence of part processing factors on image quality.
