Description

Technical Field

[0001] This utility model relates to inkjet printers, and in particular to a high-precision printhead adjustment structure. Background Technology

[0002] In inkjet printers, the printhead is typically secured to the base using two locking screws. Generally, the printhead has a through hole, and the base has a threaded hole. The locking screws pass through the printhead and are threaded onto the base. Tightening the locking screws secures the printhead to the base. During use, depending on the specific printing requirements, fine-tuning of the printhead position may be necessary. This involves leaving a gap between the through hole and the locking screws. Loosening both locking screws allows for slight movement of the printhead, thus adjusting its position. Currently, the common practice is to slightly loosen the two locking screws and manually tap the printhead with a tool to move it. However, this method has a drawback: the adjustment precision is difficult to control, requiring multiple operations and adjustments to achieve the desired printhead position. Utility Model Content

[0016] Please see Figure 1 and Figure 5 A high-precision nozzle adjustment structure includes: a base 1, several nozzles 2, several pairs of locking bolts 3, several pairs of adjusters 4, and several first elastic elements 5.

[0017] Please see Figure 2 The base 1 has several mounting slots 1A, the number of which is the same as the number of nozzles 2. The base 1 has connection holes 1B on both sides of the mounting slots 1A in a horizontal longitudinal direction.

[0018] Please see Figure 3The nozzle 2 has a triangular groove 2A on its first horizontal longitudinal side. The nozzle 2 has a first abutting surface 2B and a second abutting surface 2C on its second horizontal longitudinal side. More specifically, the nozzle 2 has protrusions on both horizontal longitudinal sides, and the triangular groove 2A, the first abutting surface 2B, and the second abutting surface 2C are all provided on the corresponding protrusions.

[0019] Please see Figure 4 and Figure 5 A pair of locking bolts 3 are used to fix the nozzle 2 and the mounting groove 1A. More specifically, the nozzle 2 is inserted into the mounting groove 1A until the bottom surfaces of the two protrusions abut against the top surface of the base 1. Both protrusions have through holes 2D. The base 1 has fixing holes 1C on both sides of the mounting groove 1A in the horizontal longitudinal direction. The locking bolts 3 can pass through the through holes 2D and be threaded into the fixing holes 1C.

[0020] Correspondingly, since there is a gap between the locking bolt 3 and the through hole 2D, the nozzle 2 is not fixed when the locking bolt 3 is not tightened, and its position can be adjusted by slight translation.

[0021] Please see Figure 5 A pair of adjusters 4 are respectively connected to two connection holes 1B corresponding to the mounting slot 1A. The adjuster 4 includes: a connecting part 41 and a movable block 42.

[0022] The connecting part 41 is fixed to the connecting hole 1B. More specifically, the connecting part 41 can be threaded to the connecting hole 1B. The movable block 42 can slide up and down and is fixed to the connecting part 41. That is, under normal circumstances, the movable block 42 is equivalent to the connecting part 41 being fixed. Through the corresponding structure, the fixed position of the movable block 42 relative to the connecting part 41 can be adjusted up and down.

[0023] Please see Figure 6 and Figure 7 In some embodiments, the connecting portion 41 of the adjuster 4 includes a connecting rod 411, an adjusting sleeve 412, and a second elastic member 413. The connecting rod 411 is used for connecting the movable block 42, and the adjusting sleeve 412 is threadedly connected to the connecting rod 411. More specifically, the connecting rod 411 can be, from top to bottom, a first threaded section 411A, a smooth section 411B, and a second threaded section 411C. The smooth section 411B has the largest outer diameter, and the inner diameter of the hole through which the connecting rod 411 passes in the movable block 42 matches the outer diameter of the smooth section 411B. The second threaded section 411C is used for threaded connection with the connecting hole 1B. The second elastic member 413 is disposed between the connecting rod 411 and the movable block 42, and is used to cause the movable block 42 to press upward against the adjusting sleeve 412. More specifically, the second elastic member 413 can be a compression spring, sleeved on the first threaded section 411A.

[0024] Rotating the adjusting sleeve 412 causes it to move up and down relative to the connecting rod 411. Under the action of the compression spring, the movable block 42 remains against the adjusting sleeve 412 and moves up and down with the adjusting sleeve 412.

[0025] Please see Figure 6 Furthermore, each of the two opposite positions of the smooth segment 411B has a first notch 411D. Accordingly, the two first notches 411D form two parallel planes.

[0026] A wrench can be used to rotate the connecting rod 411 by engaging the two planes, and the connecting rod 411 is threaded into the connecting hole 1B of the base 1. Alternatively, the hole of the adjusting sleeve 412 through which the connecting rod 411 passes can be designed to fit the two planes, thus restricting the rotation of the adjusting sleeve 412 relative to the connecting rod 411.

[0027] Please see Figure 5 The movable block 42 has a conical surface 42A, which corresponds to a triangular groove 2A or a first abutting surface 2B. That is, in a pair of adjusters 4, the conical surface 42A of one adjuster 4 corresponds to the triangular groove 2A, and the conical surface 42A of the other adjuster 4 corresponds to the first abutting surface 2B.

[0028] The first elastic element 5 is disposed between the base 1 and the nozzle 2, and acts on the second abutment surface 2C. The second abutment surface 2C is inclined, and the force of the first elastic element 5 on the second abutment surface 2C is along the normal direction of the second abutment surface 2C. The second abutment surface 2C is designed to be inclined so that the force of the first elastic element 5 on the nozzle 2 has components in both the horizontal and vertical directions.

[0029] Please see Figure 4 In some embodiments, the first elastic element 5 is a spring sheet. The spring sheet is bent and includes: an inverted V-shaped sheet body 51 and a connecting sheet body 52 extending outward from one side of the inverted V-shaped sheet body 51. The connecting sheet body 52 can be fixedly connected to the base 1 by screws.

[0030] Under the action of the horizontal transverse force, the first abutting surface 2B abuts against the corresponding conical surface 42A. Under the action of the horizontal longitudinal force, the two inner walls of the triangular groove 2A also abut against the corresponding conical surface 42A.

[0031] After the locking bolt 3 connects the nozzle 2 and the base 1, do not tighten the locking bolt 3 immediately.

[0032] As the movable block 42 adjusts its position up and down, the parts with different outer diameters on the conical surface 42A contact the two inner walls of the triangular groove 2A, which, in conjunction with the first elastic element 5, can cause the nozzle 2 to move in the horizontal longitudinal direction, thereby adjusting the position of the nozzle 2.

[0033] As the movable block 42 adjusts its position up and down, different outer diameter parts of the conical surface 42A come into contact with the first abutting surface 2B and engage with the first elastic element 5, which can cause the nozzle 2 to swing around the axis of the conical surface 42A in the triangular groove 2A, thereby adjusting the position of the nozzle 2.

[0034] After adjusting the position of nozzle 2, tighten the two locking bolts 3 to fix nozzle 2 to base 1.

[0035] Please see Figure 3 In some embodiments, the nozzle 2 has a second notch 2E on its second side in a horizontal longitudinal direction. The first abutting surface 2B is the corresponding inner wall of the second notch 2E.

[0036] The design of the first notch 411D reduces the distance between the first abutting surface 2B and the second abutting surface 2C, allowing for more efficient use of the space on the base 1 to accommodate the connecting hole 1B. Correspondingly, the other inner wall of the second notch 2E and the adjuster 4 are appropriately spaced in the horizontal direction to prevent interference during the adjustment of the nozzle 2 position.

[0037] Please see Figure 1 and Figure 2 In some embodiments, there are multiple mounting slots 1A, divided into a first group and a second group. Both the first group and the second group are arranged horizontally, with their adjacent sides interlaced. This balances the coverage of the spraying area and the uniformity of the spraying.

[0038] Please see Figure 1 and Figure 2 In some embodiments, the base 1 also has a groove 1D, within which a heat tracing cable 6 is disposed. The nozzle 2 is brought to a suitable temperature by electric heating.
