Description

Technical Field

[0001] This invention relates to the field of printhead installation and adjustment technology, specifically a printhead installation and adjustment mechanism. Background Technology

[0002] The printhead is the core and most precise component of an inkjet printer. Its function is to receive computer image signals and eject micron-sized ink droplets, which precisely land on paper, plastic, or fabric to form text and images. The printhead mounting mechanism is a set of mechanical components assembled between the printer carriage base and the printhead mounting base. It is used to support and fix the printhead and can perform multi-degree-of-freedom position, tilt angle calibration, alignment, and locking of the printhead.

[0003] However, current printhead installation typically involves directly placing the printhead mounting plate into the mounting slot, using the inner bottom surface of the base plate as a reference surface. The mounting slot lacks a positioning mechanism, resulting in a large reference surface and limited initial positioning. This hinders quick pre-positioning of the printhead mounting plate, slowing down the installation process. The printhead mounting plate is secured with locking bolts, and fine-tuning the printhead's position relies solely on manual bending followed by screw tightening, leading to low precision. Traditional printhead mounting plates have short locking and adjusting bolts, making it difficult to reach in and adjust high-capacity printheads, and these bolts are hard to find. High-capacity printheads also result in numerous pipes and wiring harnesses after installation. The lack of a cable management mechanism on the mounting box leads to tangled wiring, which can interfere with adjusting and locking bolts, scratch external cables, damage hoses and signal cable sheaths, and cause tangling between wires. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a printhead mounting and adjustment mechanism.

[0005] The technical solution adopted by this invention to solve its technical problem is: a printhead mounting and adjusting mechanism, including a base plate, a plurality of mounting slots formed on the base plate, a mounting plate installed inside the mounting slots, an inkjet mechanism installed on the mounting plate, a positioning mechanism installed inside the mounting slots, an adjusting mechanism installed on the inner side of the positioning mechanism and the mounting slots, and a fastening mechanism installed on the mounting plate. The positioning mechanism is used to quickly pre-position the mounting plate inside the mounting slots, and the adjusting mechanism is used to finely adjust the position and angle of the mounting plate inside the mounting slots. The positioning mechanism includes a first protrusion and a second protrusion. The inner sidewall of the mounting slot is integrally formed with the first protrusion. One of the inner sides of the mounting plate has a protrusion 2 integrally formed. The sidewall of the protrusion 1 is perpendicular to the sidewall of the protrusion 2. The adjustment mechanism includes an adjusting bolt 1, a fixing block, an adjusting bolt 2, and an abutment block. The other inner side of the mounting groove has a fixing block integrally formed. The protrusion 1 and the fixing block are respectively threaded with adjusting bolt 1 and adjusting bolt 2. The bottom of the adjusting bolt 1 and adjusting bolt 2 is provided with an inclined surface. The inclined surface of one sidewall of the adjusting bolt abuts against the edge of the sidewall of the mounting plate. The upper right surface of the mounting plate is fixedly connected with an abutment block. The inclined surface of the adjusting bolt 2 abuts against the edge of the sidewall of the abutment block. There is a gap between the mounting plate and the fixing block.

[0006] Specifically, the bottom and top of the adjusting bolt one and adjusting bolt two are cylindrical, and the connection between the two cylinders is a frustum-shaped structure that is larger at the top and smaller at the bottom.

[0007] Specifically, the cross-section of the abutment block is L-shaped, and the surface of the abutment block is lower than the inclined part of the adjusting bolt two.

[0008] Specifically, the fastening mechanism includes two movable ports. The mounting plate has two movable ports facing each other, and the base plate has two locking holes located at the bottom of the movable ports facing each other. Locking bolt one and locking bolt two are respectively inserted into the two movable ports. Locking bolt one and locking bolt two are threadedly connected to the two locking holes. Locking bolt one and locking bolt two are both extended. The cross-section of the mounting plate and the mounting groove is T-shaped, and the inner diameter of the mounting groove is larger than the inner diameter of the mounting plate.

[0009] Specifically, the bottoms of both locking bolt one and locking bolt two are T-shaped, the diameter of the movable opening is larger than the diameter of the T-shaped part at the bottom of locking bolt one and locking bolt two, and the diameter of the movable opening is larger than the diameter of the locking hole.

[0010] Specifically, the locking bolt one and the locking bolt two are provided with a foolproof mechanism, which includes a disassembly groove one. The top of the locking bolt one and the locking bolt two are both provided with a disassembly groove one, and the top of the adjusting bolt one and the adjusting bolt two are both provided with a disassembly groove two.

[0011] Specifically, the first disassembly groove has a straight-line structure, and the second disassembly groove has a cross-shaped structure.

[0012] Specifically, the inkjet mechanism includes a mounting base, and four mounting bases are mounted in a rectangular array on the mounting plate. Each of the four mounting bases is fixedly connected to a connecting rod, a quick-connect female is mounted on the connecting rod, a quick-connect nozzle is mounted on the quick-connect female, and a printhead is mounted on the quick-connect nozzle.

[0013] Specifically, a fixing box is fixedly connected to the mounting plate, and a wire take-up mechanism is installed on the fixing box. The wire take-up mechanism includes a wire groove. Two sets of wire grooves are opened on both sides of the fixing box. Two fixing strips are installed on both sides of the fixing box. T-shaped sliding rods are fixedly connected to the two fixing strips at equal intervals. A baffle is slidably connected to the sliding rod. The baffle is located outside the wire groove, and an elastic element is provided between the baffle and the fixing strip.

[0014] Specifically, the two baffles on the same side are provided with turning grooves at opposite ends, and the turning grooves have a stepped structure.

[0015] The beneficial effects of this invention are: 1. The present invention provides a printhead mounting and adjusting mechanism, wherein a positioning mechanism and an adjusting mechanism are installed inside the mounting slot. The positioning mechanism is mainly used for quick pre-positioning when the mounting plate is inserted into the mounting slot, limiting the initial offset of the mounting plate and completing coarse positioning assembly. The adjusting mechanism is used for precise fine-tuning of the position and angle of the pre-positioned mounting plate to correct installation deviations. A fastening mechanism is also installed on the mounting plate to lock and fix the mounting plate after fine-tuning, ensuring the stability of the printhead operation. The inner sidewall of the mounting slot is integrally formed with a protrusion. One of the adjacent inner sides is integrally formed with a second protrusion, and the sidewall of the first protrusion is perpendicular to the sidewall of the second protrusion, forming a right-angle positioning reference. During the process of inserting the mounting plate into the mounting slot, the right-angle limiting structure of the first and second protrusions can quickly engage the corners of the mounting plate, limiting the initial horizontal and vertical positions of the mounting plate and preventing large-scale displacement after the mounting plate is inserted, thus achieving rapid pre-assembly positioning. After pre-positioning, the horizontal and vertical positions of the mounting plate can be finely adjusted by the adjustment mechanism, and then fixed by the fastening mechanism. The installation speed is fast, no manual prying is required, and the adjustment accuracy is high.

[0016] 2. The printhead installation and adjustment mechanism of the present invention includes a foolproof mechanism on the fastening mechanism and the adjustment mechanism. The top center of both locking bolt one and locking bolt two has a slotted groove with a flathead screwdriver for disassembly and assembly only; while the top center of both adjusting bolt one and adjusting bolt two has a cross-shaped slotted groove for disassembly and assembly only. The foolproof function is achieved through these different slotted structures, effectively preventing bolt jamming caused by the mixing of tools during disassembly and assembly.

[0017] 3. The printhead mounting and adjusting mechanism of the present invention includes a fixing box mounted on the mounting plate, and wire winding mechanisms mounted on both sides of the fixing box. The wire winding mechanisms can store the printhead's tubing, preventing it from affecting the rotation of the adjusting mechanism and the fastening mechanism, and preventing damage to the wires themselves. The fixing box has wire grooves on both sides for storing the wire harness. A baffle is provided on the outside of the wire groove to block the tubing. The baffle slides on the outside of the slide rod. An elastic element is fixedly assembled between the baffle and the fixing strip. The elastic element is normally in a relaxed state, pushing the baffle to fit against the outside of the wire groove, realizing the closed storage of the cable, preventing the cable from falling off, being exposed and worn, and avoiding the wire harness and tubing from being messy and affecting the operation of the adjusting mechanism and the fastening mechanism.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-10 As shown, a printhead mounting and adjusting mechanism of the present invention includes a base plate 1. Multiple mounting slots 2 for assembly and positioning are evenly distributed on the base plate 1. A matching mounting plate 9 is detachably mounted inside each mounting slot 2. The mounting plate 9 serves as a carrier for the printhead 705, and an inkjet mechanism 7 for printing operations is fixedly mounted on it. To achieve high-precision installation and adjustment of the printhead 705, a positioning mechanism 3 is integrated inside the mounting slot 2. An adjusting mechanism 4 is mounted in the area on the inner wall of the mounting slot 2 that cooperates with the positioning mechanism 3. A fastening mechanism 6 is also mounted on the mounting plate 9. The positioning mechanism 3 is mainly used for quick pre-positioning of the mounting plate 9 when it is inserted into the mounting slot 2, limiting the initial offset of the mounting plate 9 and completing coarse positioning assembly. The adjusting mechanism 4 is used for precise fine-tuning of the position and angle of the pre-positioned mounting plate 9 to correct installation deviations. The fastening mechanism 6 is used to lock and fix the mounting plate 9 after fine-tuning, ensuring the stability of the printhead 705 during operation.

[0023] Specifically, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the positioning mechanism 3 includes vertically arranged protrusion 1 301 and protrusion 2 302. The inner sidewall of the mounting groove 2 is integrally formed with protrusion 1 301, and an adjacent inner sidewall of the mounting groove 2 is integrally formed with protrusion 2 302. The sidewall of protrusion 1 301 and the sidewall of protrusion 2 302 are perpendicular to each other, forming a right-angle positioning reference. During the process of mounting plate 9 being installed into mounting groove 2, the right-angle limiting structure of protrusion 1 301 and protrusion 2 302 can quickly engage the corner position of mounting plate 9, limiting the initial horizontal and vertical position of mounting plate 9, avoiding large-scale displacement of mounting plate 9 after installation, realizing rapid pre-assembly positioning, greatly improving the assembly efficiency in the early stage of installation, and providing a precise reference for subsequent fine-tuning operations.

[0024] Specific, reference Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the adjustment mechanism 4 is equipped with a positioning mechanism 3, specifically including an adjusting bolt 401, a fixing block 402, an adjusting bolt 403, and a contact block 404. The fixing block 402 is integrally formed on the other inner side of the mounting groove 2. The fixing block 402 corresponds to the position of the protrusion 301. The adjusting bolt 401 is threaded through the surface of the protrusion 301, and the adjusting bolt 403 is threaded through the surface of the fixing block 402. The bottom ends of the adjusting bolt 401 and the adjusting bolt 403... Both the top and bottom sections are smooth cylindrical structures, and the connection between the upper and lower cylindrical sections is a truncated cone-shaped inclined surface structure with the upper section being larger than the lower section. This inclined surface is the main working surface for adjusting the contact. At the same time, a contact block 404 is fixedly connected to the upper right surface of the mounting plate 9. The overall cross-section of the contact block 404 is an L-shaped structure, and the height of the upper surface of the contact block 404 is lower than the height of the inclined surface of the adjusting bolt 403, ensuring that when the adjusting bolt 403 is pressed down for adjustment, its inclined surface can accurately fit the side edge of the contact block 404.

[0025] During fine-tuning, after the mounting plate 9 is pre-positioned, a fine-tuning gap is reserved between the mounting plate 9 and the fixing block 402 to provide room for adjustment of position and angle. The operator screws the adjusting bolt 401 to move it vertically downward along the threaded hole of the protrusion 301. The truncated cone inclined surface of the side wall of the adjusting bolt 401 continuously abuts and presses against the side edge of the mounting plate 9. The inclined surface pressing force pushes the mounting plate 9 to move horizontally slightly, realizing fine-tuning of the position of the mounting plate 9 on one side. When the adjusting bolt 403 is screwed, the adjusting bolt 403 moves vertically downward, and its inclined surface abuts and presses against the side edge of the L-shaped contact block 404, pushing and fine-tuning the other side of the mounting plate 9. Through the coordinated adjustment of the two sets of adjusting bolts, the horizontal position and installation tilt of the mounting plate 9 can be accurately corrected, eliminating the deviation caused by the assembly gap and ensuring the printing accuracy of the subsequent printhead 705.

[0026] Specifically, refer to Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the fastening mechanism 6 is used to lock and fix the mounting plate 9 after fine adjustment. Specifically, it includes two symmetrically opened movable openings 602. The surface of the mounting plate 9 has two elongated movable openings 602 facing each other. The surface of the base plate 1 has two locking holes 604 facing each other at the bottom position of the movable openings 602. The matching locking bolt 1 601 and locking bolt 2 603 are respectively inserted into the two movable openings 602. The bottom of locking bolt 1 601 and locking bolt 2 603 are respectively threaded to the corresponding locking holes 604. In this embodiment, locking bolt 1 601 and locking bolt 2 603 are both designed with an extended structure to adapt to the assembly requirements of mounting plates 9 of different thicknesses, while ensuring the engagement length of the threaded locking, improving locking stability, facilitating installation and adjustment, and making it easy to locate.

[0027] Furthermore, both the mounting plate 9 and the mounting groove 2 have a T-shaped cross-section, and the inner diameter of the mounting groove 2 is larger than the outer diameter of the mounting plate 9. This allows the mounting plate 9 to slide and deflect within a small range inside the mounting groove 2, accommodating fine-tuning requirements. Simultaneously, the bottoms of locking bolt 601 and locking bolt 603 are T-shaped, with the diameter of the movable opening 602 larger than the maximum outer diameter of the T-shaped structure at the bottom of the locking bolt, and the diameter of the movable opening 602 larger than the diameter of the locking hole 604. This structural design ensures that the locking bolts can move slightly within the movable opening 602 when not fully locked, accommodating positional deviations after fine-tuning of the mounting plate 9. After fine-tuning, pressing down and tightening locking bolts 601 and 603 ensures that the bottom of the bolts is fully threaded into the locking hole 604, firmly fixing the mounting plate 9 inside the mounting groove 2 and preventing loosening or displacement during operation.

[0028] Specifically, refer to Figure 7 As shown, to distinguish disassembly and assembly tools and avoid assembly confusion, locking bolt 1 601 and locking bolt 2 603 are equipped with a foolproof mechanism 5. The foolproof mechanism 5 includes a disassembly groove 1 501 and a disassembly groove 2 502. The top center of both locking bolt 1 601 and locking bolt 2 603 has a slotted groove 1 501 with a flathead screwdriver for disassembly and assembly only. The top center of both adjusting bolt 1 401 and adjusting bolt 2 403 has a cross-shaped disassembly groove 2 502 for disassembly and assembly only. The foolproof function is achieved through the different structures of the grooves, which effectively avoids the situation of mixed tools and incorrect bolt installation during disassembly and assembly by the staff, and improves the convenience and standardization of equipment assembly and maintenance.

[0029] Specifically, refer to Figure 5 and Figure 9As shown, the inkjet mechanism 7 is the core printing structure of the equipment, fixedly mounted on the mounting plate 9. Specifically, it includes a mounting base 701, a connecting rod 702, a quick-connect female connector 703, a quick-connect nozzle 704, and a printhead 705. Four mounting bases 701 are fixedly mounted in a rectangular array on the surface of the mounting plate 9. The top of each of the four mounting bases 701 is vertically fixedly connected to a connecting rod 702. The top of the connecting rod 702 is fixedly mounted with a quick-connect female connector 703. The quick-connect female connector 703 can be detachably inserted into the quick-connect nozzle 704. The bottom of the quick-connect nozzle 704 is fixedly mounted with the printhead 705 for inkjet printing. The insertion and mating structure of the quick-connect female connector 703 and the quick-connect nozzle 704 allows for quick disassembly, replacement, and maintenance of the printhead 705 without disassembling the entire mounting plate 9, greatly reducing the difficulty of equipment maintenance. At the same time, the four sets of printheads 705 arranged in a rectangular array can effectively improve the efficiency and coverage of printing operations.

[0030] Specifically, refer to Figure 9 and Figure 10 As shown, to organize the connection lines of the nozzle 705 and avoid messy wear, a fixing box 10 is fixedly installed on the mounting plate 9. A cable winding mechanism 8 is assembled on the outside of the fixing box 10 to store and organize the connection cables of the nozzle 705. The cable winding mechanism 8 includes a cable groove 803, a fixing strip 801, a baffle 802, a sliding rod 804, and an elastic element 805. Two sets of cable grooves 803 for storing cables are symmetrically opened on the left and right sides of the fixing box 10. Two symmetrically arranged fixing strips 801 are fixedly installed on the left and right side walls of the fixing box 10. Multiple T-shaped sliding rods 804 are fixedly connected at equal intervals on the surface of the same fixing strip 801. A baffle 802 is slidably sleeved on the outside of the sliding rod 804. The baffle 802 is set to fit the outside of the cable groove 803 as a whole, which can shield and protect the cable groove 803.

[0031] Furthermore, an elastic element 805 is fixedly assembled between the baffle 802 and the fixing strip 801. The elastic element 805 is preferably a spring. Under normal conditions, the elastic element 805 is in a relaxed state, pushing the baffle 802 to fit against the outside of the cable tray 803, thereby achieving closed cable storage, preventing the cable from falling off, being exposed and worn, and avoiding the interference of messy wire harnesses and pipes on the operation of the adjustment mechanism 4 and the fastening mechanism 6. When it is necessary to organize or repair the cable, the baffle 802 can be manually pulled to slide along the slide rod 804 to compress the elastic element 805, exposing the internal space of the cable tray 803. After the operation is completed, the baffle 802 is released. Under the elastic force of the elastic element 805, the baffle 802 automatically resets and covers the cable tray 803. At the same time, the opposite ends of the two baffles 802 arranged on the same side are provided with stepped turning grooves 806. The turning grooves 806 can limit and guide the cable direction, avoiding excessive bending and damage to the cable, and further improving the neatness and protection of the cable storage.

[0032] When using this invention First, align the mounting plate 9 with the mounting slot 2 and insert it. Quickly position it using protrusion 301 and protrusion 302. Then, precisely fine-tune the position and angle of the mounting plate 9 by turning adjusting bolts 401 and 403, utilizing the principle of inclined plane contact, to correct assembly deviations. After fine-tuning, thread locking bolts 601 and 603 through the movable opening 602 and locking hole 604. Note that when adjusting the mounting plate 9 back and forth by rotating adjusting bolt 403, slightly tighten locking bolt 601, but do not tighten locking bolt 603. After adjustment, tighten both bolts to secure the mounting plate 9. Finally, complete the quick-connect assembly of the inkjet mechanism 7 and store the printhead cable inside the take-up mechanism 8, completing the overall installation. During disassembly and maintenance, the corresponding bolts can be quickly disassembled using the appropriate tools matching disassembly slots 501 and 502 for easy retrieval.
