[0006] The first mounting part is fixedly connected to the base plate; it has an insertion port for the first protrusion of the digital inkjet head to be inserted longitudinally, and the outer wall of the insertion port also has an arc notch corresponding to each strip groove, the arc notch for the first feed tube of the digital inkjet head to be abutted longitudinally.
[0007] The second mounting part is slidably connected to the base plate along the longitudinal direction. Each strip groove has a triangular or trapezoidal protrusion, which is used to abut against the triangular notch of the digital inkjet head from the longitudinal direction.
[0008] The linear drive unit is used to move the second mounting unit.
[0009] In some embodiments, the first mounting part includes: a base, a top plate, and a plurality of mounting blocks; the base has a recess; the top plate is fixedly connected to the base, such that the recess forms the insertion port, and the top plate also has a mounting notch corresponding to each strip groove; the arc notch is provided on the mounting block, and the mounting block is fixedly connected to the mounting notch.
[0010] In some embodiments, the first mounting part includes: a base, a top plate, and a plurality of mounting blocks; the base has a recess; the top plate is fixedly connected to the base, such that the recess forms the insertion port, and the top plate also has a mounting notch corresponding to each strip groove; the arc notch is provided on the mounting block, and the mounting block is fixedly connected to the mounting notch.

[0031] Please see Figure 2 and Figure 3 A fixture for a digital inkjet printer head 5 includes: a base plate 1, a first mounting part 2, a second mounting part 3, and a linear drive part 4.
[0032] Please see Figure 1 The digital inkjet head 5 to be held by the fixture has a first protrusion 5a and a second protrusion 5b on its longitudinal sides respectively. The top surface of the first protrusion 5a has a first feed tube 5c, the top surface of the second protrusion 5b has a second feed tube 5d, and the side of the second protrusion 5b has a triangular notch 5e.
[0033] Please see Figure 2 and Figure 3 The base plate 1 has multiple strip grooves 1a arranged side by side in a transverse direction, while each individual strip groove 1a is longitudinal. Each strip groove 1a has an abutting surface 1b at one longitudinal end, which is used for the portion of the digital inkjet head 5 below the first protrusion 5a to abut against it longitudinally.
[0034] The first mounting part 2 is fixedly connected to the base plate 1. The first mounting part 2 has an insertion port 2a, which is used for the first protrusion 5a of the digital inkjet head 5 to be inserted longitudinally. The outer wall of the insertion port 2a also has an arc notch 2b corresponding to each strip groove 1a, which is used for the first feed tube 5c of the digital inkjet head 5 to abut against it longitudinally. That is, the digital inkjet head 5 has two abutting positions on the side corresponding to the first mounting part 2, one above the first protrusion 5a and one below the first protrusion 5a.
[0035] After the first protrusion 5a is inserted into the insertion port 2a, its bottom surface is supported by the inner bottom wall of the insertion port 2a. Correspondingly, the base plate 1 is also fixedly connected with a support strip 1c. The support strip 1c is located at the other end of the longitudinal direction of the strip groove 1a. The top surface of the support strip 1c is used to support the second protrusion 5b, so that the digital inkjet head 5 remains horizontal.
[0036] Please see Figure 4 In some embodiments, the first mounting part 2 includes: a base 21, a top plate 22 and a plurality of mounting blocks 23.
[0037] The base 21 has a notch 21a. More specifically, the base 21 can be composed of a horizontal plate and multiple vertical plates integrally set on the horizontal plate. A notch 21a is formed between two adjacent vertical plates. The size of the notch 21a can be the same or different. Depending on the specific size, one first protrusion 5a can enter the notch 21a, or multiple first protrusions 5a can enter the notch 21a.
[0038] The top plate 22 is fixedly connected to the base 21. More specifically, the top plate 22 has multiple stepped through holes, and multiple vertical plates have threaded holes on their top surfaces. The top plate 22 and the base 21 are fixedly connected by screws. After the top plate 22 is fixedly connected to the base 21, the recess 21a forms the aforementioned insertion port 2a. The top plate 22 also has an installation notch 22a corresponding to each strip groove 1a.
[0039] An arc notch 2b is provided on the mounting block 23, and the mounting block 23 is fixedly connected to the mounting notch 22a. More specifically, both the mounting block 23 and the mounting notch 22a can be convex, and are fixedly connected with screws, referring to the top plate 22 and the base 21.
[0040] Please see Figure 2 The second mounting part 3 is slidably connected to the base plate 1 along the longitudinal direction. More specifically, a first guide post 1d is fixedly connected to both sides of the base plate 1 in the lateral direction, and a linear bearing is fixedly connected to both sides of the second mounting part 3 in the lateral direction. The linear bearing is matched with the first guide post 1d.
[0041] The second mounting part 3 has a triangular or trapezoidal protrusion 3a corresponding to each strip groove 1a. The protrusion 3a is used to abut against the triangular notch 5e of the digital inkjet head 5 from the longitudinal direction, so that the part below the first protrusion 5a abuts against the abutting surface 1b, and the first feed tube 5c abuts against the arc notch 2b, thereby achieving clamping and fixing of the digital inkjet head 5.
[0042] Please see Figure 5 In some embodiments, the second mounting portion 3 includes a mounting portion 31 and a plurality of abutting portions 32. The mounting portion 31 is used for sliding connection with the base plate 1, that is, the linear bearing is fixedly connected to the mounting portion 31. The plurality of abutting portions 32 are all slidably connected to the mounting portion 31 in the transverse direction. More specifically, the mounting portion 31 may have a strip-shaped through groove 31a; the abutting portion 32 may be U-shaped, with the vertical section being the protrusion 3a, and the horizontal section inserted into the strip-shaped through groove 31a. The end face of the horizontal section may also be fixedly connected to a stop 32a by screws. The stop 32a and the vertical section respectively fit against the outer walls of the longitudinal sides of the mounting portion, so that the stop 32a and the vertical section can fit tightly against the mounting portion, generating friction, so that the abutting portion has a damping effect when sliding relative to the mounting portion 31.
[0043] Multiple protrusions 3a need to correspond to the triangular notches 5e of multiple digital inkjet printheads 5 at one time. If the protrusions 3a are integrally set on the second mounting part 3, the machining accuracy requirements for the position of the protrusions 3a are relatively high. The abutting parts 32 are all slidably connected to the mounting part 31 in the lateral direction. When the protrusions 3a are about to enter the triangular notches 5e, the abutting parts 32 can be adjusted to ensure that multiple protrusions 3a can correspond to multiple triangular notches 5e, and that the protrusions 3a can still maintain the clamping and fixing of the digital inkjet printheads 5 after they abut against the triangular notches 5e.
[0044] Please participate Figure 1 The linear drive unit 4 is used to drive the second mounting unit 3 to move.
[0045] In some embodiments, a lead screw module is selected as the linear drive unit 4. More specifically, the lead screw 41 of the lead screw module can be rotatably connected to the top surface of the base plate 1 through two bearing seats, and the lead screw 41 nut is fixedly connected to the second mounting part 3. Manually rotating the lead screw 41 causes the second mounting part 3 to slide, thereby clamping / releasing the digital inkjet head 5.
[0046] Correspondingly, although the structure of the lead screw module is relatively simple using this method, the second mounting part 3 needs to be divided into two groups, the multiple strip grooves 1a also need to be divided into two groups, and the support bar 1c also needs to be divided into two pieces. Appropriate intervals need to be left between the two groups of second mounting parts 3, between the two groups of strip grooves 1a, and between the two support bars 1c for the lead screw 41 to be installed, that is, the multiple strip grooves 1a cannot be installed at equal intervals.
[0047] Please see Figure 6 In some embodiments, the bottom surface of the base plate 1 has a set of support feet 1e, providing a mounting space on the bottom surface of the base plate 1. A lead screw module is mounted on the bottom surface of the base plate 1. More specifically, the base plate 1 can be fixedly connected to two second guide posts 1f via the support feet 1e. The lead screw 41 of the lead screw module can be rotatably connected to the bottom surface of the base plate 1 via two bearing seats. A mounting slider 42 is fixedly connected to a linear bearing matching the second guide posts 1f and a lead screw 41 nut matching the lead screw 41. The mounting slider 42 is concave, and the second mounting part 3 is fixedly connected to the mounting slider 42.
[0048] In this way, the lead screw module does not occupy the space on the top surface of the bottom plate 1, the second mounting part 3 does not need to be divided into two groups, the multiple strip grooves 1a do not need to be divided into two groups but can be set at equal intervals, and the support bar 1c does not need to be divided into two bars.
[0049] In some embodiments, locking members 3b are installed on both sides of the second mounting part 3 laterally. The locking members 3b are used to restrict the movement of the second mounting part 3 relative to the base plate 1. More specifically, for the two linear bearings of the second mounting part 3, locking members 3b can be used, i.e., the locking members 3b are set on the linear bearings; alternatively, linear guides can be used to replace the two first guide posts 1d, and the locking members 3b can be guide rail clamps.
[0050] In this way, after the second mounting part 3 is moved to clamp and fix the digital inkjet head 5, the second mounting part 3 is locked by the locking member 3b to prevent loosening, so that the digital inkjet head 5 is clamped and fixed more stably.
[0051] Please see Figure 7In some embodiments, the locking member 3b may also be in the form of an elastic collet. The locking member 3b includes a sleeve 3b1 and a nut 3b2. The sleeve 3b1 is sleeved on the first guide post 1d, and the first end may have a flange, which is used to fix it to the second mounting part 3. The outer wall of the sleeve 3b1 has an external thread 3b1a and a slit penetrating the second end face. The nut 3b2 is threadedly connected to the sleeve 3b1.
[0052] When nut 3b2 is tightened, the outer wall of sleeve 3b1 is subjected to radial pressure, the gap closes, and the inner wall grips the first guide post 1d to lock it in place. After moving the second mounting part 3 to clamp and fix the digital inkjet head 5, the second mounting part 3 only needs to be prevented from loosening in the direction away from the digital inkjet head 5. It is suitable for the form of a flexible chuck, and the sleeve 3b1 adopts an external thread 3b1a with the corresponding direction of rotation.
