Description
Technical Field
The present invention relates to a nozzle adjustment mechanism, and more particularly to a dual nozzle adjustment mechanism capable of achieving parallel alignment quickly.
Background
In recent years, the demand for the printing quality of the ink jet printer has been increasing. Although dots tend to be smaller as the resolution increases, ink jet printers are required to meet the demand for high speed printing. In this case, the influence of the precision of the parts processing and assembling on the printing quality becomes more remarkable. However, the requirement for high precision in many processing techniques is often accompanied by a significant increase in manufacturing costs and an increase in the fraction defective. Therefore, the design of the nozzle adjustment mechanism has been proposed in the market to solve the above-mentioned problems, so as to reduce the influence of the processing factors of the parts on the image quality.
In a conventional nozzle adjustment mechanism, a corresponding adjustment mechanism is disposed near each nozzle, and usually installation or service personnel are required to optimize the hand feeling during continuous adjustment and testing, which often takes a long time to perform adjustment. On the other hand, the conventional nozzle adjustment mechanism has a complex structure, a single adjustment unit corresponds to a single nozzle, and for a printer with multiple nozzles, the corresponding relationship between each nozzle must be repeatedly determined to achieve the purpose of adjusting the nozzles. Because the traditional nozzle adjusting mechanism has high manufacturing cost and complex adjusting procedure, the actual application requirements cannot be met.
Therefore, how to develop a dual nozzle adjustment mechanism to solve the problems faced by the prior art is an urgent issue in the field.

In the present embodiment, two adjacent sides of the second nozzle 4b abut against the fourth positioning protrusion 41, the fifth positioning protrusion 42 and the sixth positioning protrusion 43. Therefore, the first nozzle 4a and the second nozzle 4b can be stably disposed on the carrier 3 and kept parallel to each other.

Similarly, the fourth positioning protrusion 41 and the fifth positioning protrusion 42 abut against a long side 4b1 of the second nozzle 4b, and a distance from the fourth positioning protrusion 41 to the fifth positioning protrusion 42 is greater than one half of the long side 4b1 of the second nozzle 4b, so that the second nozzle 4b is stably disposed on the first accommodating seat 40. In addition, the sixth positioning protrusion 43 abuts against a short side 4b2 of the second nozzle 4b, and the second nozzle 4b is correctly disposed on the second accommodating seat 40 by three-point positioning.
In addition, when two adjacent sides of the first nozzle 4a abut against the first positioning protrusion 31, the second positioning protrusion 32 and the third positioning protrusion 33, in order to stably fix the first nozzle 4a on the carrier plate 3, the dual nozzle adjustment mechanism 1 includes at least two fixing pressing blocks 70 respectively abutting against two opposite ends of the first accommodating seat 30, and when two adjacent sides of the first nozzle 4a abut against the first positioning protrusion 31, the second positioning protrusion 32 and the third positioning protrusion 33, the first nozzle 4a is stably fixed on the first accommodating seat 30. Similarly, in the present embodiment, the dual nozzle adjustment mechanism 1 includes at least two fixing pressing blocks 70 respectively disposed adjacent to two opposite ends of the second accommodating seat 40, and when two adjacent sides of the second nozzle 40 abut against the fourth positioning protrusion 41, the fifth positioning protrusion 42 and the sixth positioning protrusion 43, the second nozzle 4b is stably fixed on the second accommodating seat 40. In this embodiment, the first positioning protrusion 31 and the second positioning protrusion 21 are further located on a side of the first accommodating seat 30 close to the second side 3b, and the fourth positioning protrusion 41 and the fifth positioning protrusion 42 are further located on a side of the second accommodating seat 40 close to the second side 3b, so as to facilitate a user to apply force to stably support the first nozzle 4a against the first positioning protrusion 31, the second positioning protrusion 32 and the third positioning protrusion 33 on the first accommodating seat 30, and complete the fixing by two fixing pressing blocks 70. The force of the user is also beneficial to make the second nozzle 4b stably abut against the fourth positioning protrusion 41, the fifth positioning protrusion 42 and the sixth positioning protrusion 43 on the second accommodating seat 40, and the two fixing pressing blocks 70 are used to complete the fixing. In the embodiment, the fixing pressing block 70 can fix the nozzle group 4 by a screw 71 and a corresponding screw hole 72 on the carrier plate 3, which is not limited by the invention.
In the embodiment, the adjusting element 5 may be, for example, an adjusting screw, and is disposed between the base 2 and the carrier 3 along the direction of the second side 3b. Wherein the base body 2 includes a through hole 15, the carrier plate 3 includes an engaging hole 51, and the adjusting member 5, such as an adjusting screw, is engaged with the engaging hole 51 through the through hole 15. The adjusting member 5 is engaged with the base 2 and the carrier 3, so that the carrier 3 can rotate around the pivot member 20, thereby adjusting the position of the carrier 3 relative to the base 2. Of course, the manner of driving the carrier plate 3 to move relative to the base 2 by the adjusting member 5 is not limited thereto, and will not be described again.
In addition, in the embodiment, the pivot 20 may include a pivot hole 22 and a screw 21, for example, the screw 21 is detachably connected to the base 2 through the pivot hole 22, so that the carrier 3 is pivotally connected to the base 2 through the pivot 20. In this embodiment, the base 2 further includes a first positioning post 11 disposed on the supporting platform 10 and spatially opposite to the pivot 20 of the carrier 3, wherein the first positioning post 11 is engaged with the screw 21 through the pivot hole 22, for example, so that the carrier 3 and the base 2 are pivotally connected through the first positioning post 11 and the pivot hole 22. Of course, the invention is not limited thereto. In the embodiment, the base 2 further includes a second positioning column 12 disposed on the supporting platform 10 and spatially opposite to the guiding groove 50 of the carrier 3, and a portion of the second positioning column is accommodated in the guiding groove 50, wherein when the carrier 3 rotates around the pivot 20, the guiding groove 50 slides relative to the second positioning column 12. In addition, in the embodiment, the guiding groove 50 further has a groove structure 50a, for example, penetrating through the carrier 3, and the second positioning column 12 is accommodated in the groove structure 50a and detachably connected to the locking member 60 through the groove structure 50a of the guiding groove 50. Thus, when the locking member 60 releases the guiding groove 50, the adjusting member 3 is assembled to engage with the base 2 and the carrier plate 3, and the carrier plate 3 can smoothly rotate along the guiding groove 50 with the pivot member 20 as the center, so as to achieve the purpose of adjusting the position of the carrier plate 3 relative to the base 2. In the embodiment, the guiding groove 50 and the groove structure 50a are both arc-shaped with the pivot 20 as the center. In other embodiments, the guiding groove 50 is further designed with corresponding scales to indicate the rotation angle of the carrier plate 3 relative to the base 2. However, they do not limit the essential features of the invention and are not described in detail here.
It should be noted that, in the present embodiment, the carrier 3 is formed by a metal material such as aluminum through a Computer Numerical Control (CNC) process. Since the manufacturing cost of the CNC processing technology is low, and the dimensional tolerance can be easily controlled below 0.03mm, the first accommodating seat 30 and the second accommodating seat 40 which have the same profile and are arranged in parallel with each other can be easily formed on the carrier plate 3, so as to ensure that the connecting line of the first positioning protrusion 31 and the second positioning protrusion 32 is parallel to the connecting line of the fourth positioning protrusion 41 and the fifth positioning protrusion 42, and is perpendicular to the connecting line of the third positioning protrusion 33 and the sixth positioning protrusion 43. After the first nozzle 4a and the second nozzle 4b are respectively fixed on the first containing seat 30 and the second containing seat 40 in the above manner, the first nozzle 4a and the second nozzle 4b can be aligned in parallel quickly, which is helpful for improving the efficiency of adjusting the nozzles and reducing the time consumed by the adjustment operation. Then, the carrier plate 3 is detachably disposed on the base 2 through the pivot member 20 and the guide groove 50, so that the alignment of the nozzle set 4 can be easily achieved, and the first nozzle 4a and the second nozzle 4b aligned in parallel can be quickly applied to the printing apparatus, thereby greatly improving the efficiency of the whole adjustment operation, and simultaneously reducing the number of parts required by the adjustment mechanism, improving the efficiency and reducing the cost.
In the embodiment, the base 2 includes a first opening 13 and a second opening 14, which penetrate through the supporting platform 10 and are spatially opposite to the first accommodating seat 30 and the second accommodating seat 40, respectively. When the first nozzle 4a and the second nozzle 4b are respectively assembled on the first containing seat 30 and the second containing seat 40, the nozzles of the first nozzle 4a and the second nozzle 4b can respectively perform printing through the first opening 13 and the second opening 14. The arrangement of the first opening 13 and the second opening 14 can be modulated according to the actual application requirements. However, they do not limit the essential features of the invention and are not described in detail here.
Fig. 5 is a schematic view of an initial state of the dual nozzle adjustment mechanism according to the embodiment of the invention. Refer to fig. 1 to 5. In the embodiment, the first nozzle 4a and the second nozzle 4b disposed in parallel on the carrier 3 can be used to rapidly apply the nozzle set 4 to the printing apparatus by pivoting the carrier 3 on the base 2. The first positioning protrusion 31 and the second positioning protrusion 32 abut against a long side 4a1 of the first nozzle 4b, the third positioning protrusion 33 abuts against a short side 4a2 of the first nozzle 4a, and the first nozzle 4a is correctly disposed on the first accommodating seat 30 through three-point positioning. Similarly, the fourth positioning protrusion 41 and the fifth positioning protrusion 42 abut against a long side 4b1 of the second nozzle 4b, and the sixth positioning protrusion 43 abuts against a short side 4b2 of the second nozzle 4b, so that the second nozzle 4b is correctly disposed on the second accommodating seat 40 through three-point positioning. When the locking member 60 releases the guiding groove 50, the adjusting member 3 engages the base 2 and the carrier 3, so that the carrier 3 rotates around the pivot member 20 to adjust the position of the carrier 3 relative to the base 2. In the embodiment, the carrier 3 is driven by the adjusting member 5, so that the carrier 3 can rotate relative to the base 2 within a range of an angle θ around the pivot 20. In one embodiment, for example, the adjusting member 5 pushes against the carrier 3, so that the carrier 3 rotates by an angle θ 1 around the pivot 20, as shown in fig. 6. In another embodiment, for example, the adjusting element 5 pulls the carrier 3 to rotate the carrier 3 by an angle θ 2 around the hinge 20, as shown in fig. 7. In other words, the arc length can be designed according to the actual application requirement through the guiding groove 50, and the angle θ of the rotation of the carrier plate 3 relative to the base 2 is further defined. Of course, the present invention is not limited thereto, and will not be described in detail.

In the embodiment, after the first nozzle 4a and the second nozzle 4b are disposed in parallel on the carrier 3, the carrier 3 is pivoted to the base 2 by engaging the screw 21 of the pivot 20 with the first positioning post 11. In addition, the locking member 60 penetrates through the guiding groove 50 to engage with the second positioning post 12, and further presses against the guiding groove 50 to engage with each other, so as to lock the carrier plate 3 on the base body 2, and the completed assembly structure is as shown in fig. 4.
On the other hand, when the locking member 60 releases the guiding groove 50, the adjusting member 3 is engaged with the engaging hole on the carrier 3 through the through hole 15 of the base 2, so as to push and pull the carrier 3 along the direction of the second side 3b, so that the carrier 3 rotates around the pivot member 20, the alignment of the nozzle set 4 is easily achieved, and the first nozzle 4a and the second nozzle 4b aligned in parallel are quickly applied to the printing apparatus, thereby greatly improving the efficiency of the overall adjustment operation, and simultaneously reducing the number of parts required by the adjustment mechanism, improving the efficiency and reducing the cost.
In summary, the present invention provides a dual nozzle adjustment mechanism for a printer. At least two accommodating seats arranged in parallel are formed by a metal carrier plate processed by CNC (computer numerical control), and each accommodating seat is propped against two adjacent edges of the corresponding spray head by three positioning convex parts, so that at least two spray heads can be kept in parallel. After the carrier plate is pivotally mounted on the base, the position of the carrier plate relative to the base can be adjusted by an adjusting member disposed between the carrier plate and the base, so as to quickly achieve the purpose of aligning the dual nozzles in parallel, thereby improving the efficiency of nozzle adjustment and reducing the time consumed by the adjustment operation. Moreover, the positioning convex parts are arranged on the metal carrier plate, so that the parallel alignment of the double spray heads is quickly realized. The metal carrier plate provides sufficient mechanical strength, so that the alignment accuracy of the positioning protrusions in the alignment process of repeated operation is ensured, and the positioning protrusions are not easy to deform due to frequent operation or ejection of the spray head. In addition, the CNC precision machining technology can more accurately set the positions of a plurality of positioning convex parts to realize the parallel alignment of the double spray heads, and the double spray heads which are aligned in parallel can be quickly applied to the printing device by detachably arranging a pin joint piece and a guide groove on the base body and aligning the base body driven by the transmission mechanism, thereby greatly improving the efficiency of the whole adjusting operation, simultaneously reducing the number of parts required by the adjusting mechanism, improving the efficiency and reducing the cost.
The invention may be modified in various ways by anyone skilled in the art without however departing from the scope of the appended claims.
