Description

Technical Field

[0001] This utility model relates to the field of inkjet printing equipment technology, and in particular to a combined high-speed inkjet laser printhead. Background Technology

[0002] Inkjet and laser printing equipment are key tools in modern industrial production and advertising, and their core component is the printhead body that performs the printing task. In order to meet the needs of different printing tasks, such as changing printheads of different colors and precision, or performing routine maintenance and replacement, the printhead body usually needs to be designed as a modular component that can be detached from its moving base.

[0003] As market demands for production efficiency continue to rise, printing equipment is evolving towards higher speeds. During high-speed operation, the print head undergoes intense reciprocating motion, placing extremely high demands on the stability of its mounting structure. Any slight loosening or vibration will be amplified by the high-speed motion, directly leading to problems such as blurry, misaligned, or reduced accuracy in the printed image, severely impacting product quality.

[0004] However, existing technologies often struggle to balance ease of installation and connection stability when designing printhead mounting structures. On one hand, some designs employ simple snap-fit ​​or magnetic connections for quick replacement, but these methods have limited locking force and are ill-equipped to withstand the inertial impact and vibration from high-speed movement, leading to wear and loosening after prolonged use. On the other hand, some designs use multiple screws for secure fixing, which, while reliable, makes disassembly and assembly cumbersome, requiring individual loosening and tightening of each screw, which is time-consuming and labor-intensive, significantly reducing the efficiency of equipment maintenance and printhead replacement.

[0005] Therefore, this invention proposes a combined high-speed inkjet laser printhead to address the shortcomings of existing technologies. Utility Model Content

[0006] In the existing technology, the installation structure of the combined high-speed inkjet laser printhead body makes it difficult to ensure the connection stability under high-speed operation when pursuing convenient replacement, while the disassembly and assembly operations are cumbersome and time-consuming when pursuing connection stability. The present invention aims to provide a combined high-speed inkjet laser printhead with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a combined high-speed inkjet laser printhead, comprising: a support assembly including a track; a slider slidably connected to the track; a print base fixedly connected to the slider; a printhead body; and a mounting mechanism for detachably fixing the printhead body to the print base.

[0008] The mounting mechanism includes a fixed mounting base disposed on the lower surface of the printing substrate, a replacement mounting base disposed on the upper surface of the print head body, a steel rod that can be transversely inserted through the fixed mounting base and the replacement mounting base, and a nut that is threadedly connected to one end of the steel rod.

[0009] Furthermore, the replacement mounting base is pluggable into the fixed mounting base. After the replacement mounting base and the fixed mounting base are plugged in, the steel rod passes through both and is axially locked by tightening the nut, thereby firmly fixing the print head body to the print base.

[0010] Preferably, the fixed mounting base has a mounting slot, and the replacement mounting base is inserted into the mounting slot. To guide and limit the steel rod, the replacement mounting base has a T-shaped slot, and the fixed mounting base has a limiting slot. During installation, the steel rod passes sequentially through the limiting slot and the T-shaped slot.

[0011] Preferably, to facilitate operation and provide a limiting position at one end, a first limiting block is fixedly connected to the end of the steel rod away from the nut.

[0012] Preferably, the support assembly further includes a fixing bracket, and the print head further includes a combination mechanism for detachably fixing the track to the fixing bracket, thereby enabling modular assembly of the entire support frame.

[0013] Preferably, as a specific implementation of the combined mechanism, it includes a post that can be inserted into the fixed bracket and the track, a locking block that can be retracted and installed at one end of the post, and a spring disposed in the post and abutting against the locking block, the spring being used to generate elastic force after being compressed to drive the locking block to reset.

[0014] Preferably, in order to form a bidirectional fixation, a second limiting block is fixedly connected to the end of the insertion post away from the locking block.

[0015] Preferably, in order to allow the insertion post to pass through and be positioned smoothly, the fixing bracket is provided with a matching slot for the insertion post to pass through.

[0016] Preferably, after the insertion post is installed in place, the reset locking block and the second limiting block respectively lock and fix the fixing bracket and the track from opposite sides, forming a structurally stable and non-loose whole.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of complicated and time-consuming printhead replacement operations, poor connection reliability after fixing, and easy vibration during high-speed operation in the prior art by setting up an installation mechanism consisting of a fixed mounting base, a replacement mounting base, a steel rod, and a nut. The printhead body is fixed by horizontally inserting the steel rod and locking it with the nut. This achieves the effect of convenient printhead disassembly and assembly, accurate positioning, and stable and reliable connection, effectively ensuring the accuracy of high-speed printing.

[0018] 2. This utility model, by setting up a combined mechanism consisting of a plug, a spring and a locking block, enables the rapid assembly of the track and the fixed bracket in the support component by pressing the locking block and inserting the plug. This solves the problem that the print head support frame in the prior art is mostly an integrated structure, which is inconvenient to disassemble, transport and modularly expand. It achieves the effect of stable support frame structure and easy quick disassembly and assembly, and improves the modularity and flexibility of the device.

[0019] 3. This utility model, by setting a slider that can slide along the track and cooperating with a support component that can be quickly disassembled and assembled, solves the problem in the prior art that the coverage of the printing device is fixed and it is difficult to adjust the number of print heads to improve work efficiency according to printing needs. It achieves the effect of easily increasing or decreasing the number of print heads, realizes the collaborative work of multiple print heads, and significantly improves printing efficiency and coverage.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Please refer to Figures 1 to 5 This utility model provides a combined high-speed inkjet laser printhead, which aims to solve the problems of cumbersome replacement of the printhead body 3, insufficient fixation stability, and difficulty in modular disassembly and functional expansion of the support frame in the prior art.

[0024] like Figure 1 As shown, the combined high-speed inkjet laser printhead includes a support assembly 1, a print base 2, a printhead body 3, a mounting mechanism 4, a slider 5, and a combination mechanism 6. The support assembly 1 provides a stable mounting base and motion guide for the entire device. The support assembly 1 includes two fixed brackets 101 and a track 102 connected between the two fixed brackets 101. The print base 2 is slidably connected to the track 102 via the slider 5, thereby enabling it to reciprocate along the length of the track 102. The printhead body 3, as the core component for performing the printing task, is detachably fixed to the lower surface of the print base 2 via the mounting mechanism 4.

[0025] To solve the above-mentioned technical problems, the combined high-speed inkjet laser printhead is equipped with a unique mounting mechanism 4, which forms a fast and stable assembly connection with the printing substrate 2 and the printhead body 3.

[0026] Please refer to the following carefully. Figure 1 , Figure 2 , Figure 4 and Figure 5The mounting mechanism 4 includes a fixed mounting base 401, a replacement mounting base 402, a steel rod 403, and a nut 407. The fixed mounting base 401 is fixedly disposed on the lower surface of the printing base 2, and the replacement mounting base 402 is fixedly disposed on the upper surface of the print head body 3. During assembly, the replacement mounting base 402 can be plugged into the fixed mounting base 401. In order to achieve precise alignment and load bearing, the fixed mounting base 401 is provided with a mounting slot 404, and the replacement mounting base 402 is fully inserted into the mounting slot 404.

[0027] To achieve locking and fixing, the steel rod 403 can be horizontally inserted into the fixed mounting base 401 and the replacement mounting base 402 in the assembled state. The replacement mounting base 402 has a T-shaped slot 405, while the fixed mounting base 401 has a limiting slot 408. When the steel rod 403 is inserted, it passes through the limiting slot 408 and the T-shaped slot 405 in sequence. The special T-shaped slot 405 structure can effectively prevent the steel rod 403 from accidentally coming out when it is not locked. The end of the steel rod 403 away from the nut 407 is fixedly connected to the first limiting block 406. The operator can hold the first limiting block 406 to perform insertion and removal operations. The other end of the steel rod 403 is machined with external threads. The nut 407 is screwed onto the external threads through a threaded connection, thereby firmly locking the steel rod 403 in the installation position. This structure, in which the steel rod 403 is horizontally inserted and axially locked by the nut 407, ensures extremely high reliability and vibration resistance of the connection between the print head body 3 and the print base 2.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, the modular design of support component 1 further enhances the ease of installation and structural stability of the device. Please refer to [reference needed]. Figure 1 and Figure 3 The support assembly 1 also includes a fixed bracket 101, and the rail 102 is detachably fixed to the fixed bracket 101 by the combination mechanism 6. This separate design not only facilitates transportation and installation, but also provides a basis for the expansion configuration of multiple printheads.

[0029] As a specific implementation of the combined mechanism 6, the combined mechanism 6 includes a plug 602, a locking block 604 and a spring 605. The plug 602 can be inserted into the through hole of the fixed bracket 101 and the track 102. The locking block 604 can be retracted and installed at one end of the plug 602. The spring 605 is set in the plug 602 and abuts against the locking block 604, and is used to generate elastic force after being compressed to drive the locking block 604 to reset.

[0030] To form a reliable bidirectional locking, a second limiting block 601 is fixedly connected to the end of the insertion post 602 away from the locking block 604. A matching slot 603 is correspondingly opened on the fixed bracket 101 for the insertion post 602 to pass through. When the insertion post 602 completely passes through the fixed bracket 101 and the track 102, the locking block 604, which is reset under the action of the spring 605, and the second limiting block 601 at the other end respectively lock and fix the fixed bracket 101 and the track 102 from opposite sides, forming a stable overall structure.

[0031] Working principle: When installing the printhead body 3, first align the replacement mounting base 402 on the top of the printhead body 3 with the fixed mounting base 401 below the print base 2, and insert it into the mounting slot 404. Then, hold the first limiting block 406 and pass the steel rod 403 through the limiting slot 408 of the fixed mounting base 401 and the T-shaped slot 405 of the replacement mounting base 402 in sequence. Finally, screw the nut 407 in and tighten it at the end of the steel rod 403. The printhead body 3 is firmly fixed to the print base 2 by the thread locking force.

[0032] If multiple printhead bodies 3 need to be configured, or if the support assembly 1 needs to be assembled, first align the track 102 with the installation position of the fixed bracket 101, then press the locking block 604 on the combination mechanism 6 to retract it, compress the internal spring 605, and release the locking block 604. The elastic force of the spring 605 will drive the locking block 604 to reset, so that it and the second limiting block 601 at the other end together clamp the fixed bracket 101 and the track 102 from both sides, completing the quick and stable assembly of the support assembly 1.

[0033] During the printing process, the printing substrate 2 moves smoothly and at high speed on the track 102 via the slider 5. The stable locking structure of the mounting mechanism 4 and the combination mechanism 6 together ensure that the entire device will not loosen or vibrate during high-speed operation, thus guaranteeing the accuracy and stability of printing.
