Description

Technical Field

[0001] The invention belongs to the technical field of inkjet printer nozzles, and in particular relates to a movable fixed structure for inkjet printer nozzles. Background Art

[0002] As the core executive component of digital inkjet printing equipment, the inkjet printer nozzle is mainly used to convert electronic signals into precise ink droplet ejection, achieving high-quality output of images, text or patterns on flexible or rigid media surfaces such as advertising light box cloth, car body film and architectural decoration materials. Its technical performance directly determines the inkjet printing accuracy, color reproduction, production efficiency and equipment reliability. It is a key technical unit in the fields of advertising inkjet printing, industrial printing, textile digital printing, etc.

[0003] Currently, inkjet printer nozzles generally adopt a standardized fixed installation size design. The fixed size makes it difficult to interchange nozzles from different manufacturers. When users replace nozzles, they may need to replace the entire device, which is costly. Fixed installation can make it difficult to disassemble for maintenance, especially in multi-nozzle arrays. Damage to a single nozzle may require the removal of the entire module, affecting efficiency. Fixed installation may not be able to dynamically adjust the nozzle spacing. When the nozzles are positioned offset after long-term use, they cannot be automatically calibrated, resulting in stitching errors and affecting pattern quality. Summary of the Invention

The main screw motor drives the first double-threaded screw to rotate, so that the second bevel gear drives the first bevel gear to rotate. At the same time, the first bevel gear on the other side drives the third bevel gear to rotate, so as to realize the synchronous rotation of the second double-threaded screw. The first sliding support bar and the second sliding support bar slide respectively under the rotation of the first double-threaded screw and the second double-threaded screw, thereby changing the distance between the first sliding support bar, the second sliding support bar and the fixed support bar. At the same time, the first screw motor, the second screw motor and the third screw motor respectively drive the first adjusting screw rod, the second adjusting screw rod and the third adjusting screw rod to rotate, thereby causing the nozzle support member to slide, and the sliding adjustment motor drives the third double-threaded screw rod to rotate, thereby causing the sliding support blocks to approach or move away from each other to carry nozzle mounting seats of different sizes, thereby achieving the technical effect of flexible fixation of inkjet printer nozzles of different sizes.

[0039] The first screw motor 1211 , the main screw motor 1311 , the second screw motor 231 , the third screw motor 331 , and the sliding adjustment motor 4111 are all electrically connected to an external electric control system.

[0040] Working principle and workflow:

[0041] The user selects the appropriate specification of the inkjet printer 5 according to the actual situation. Under normal circumstances, the user can fix the inkjet printer 5 on the inkjet printer mounting seat 45, and the nozzle at the lower end of the inkjet printer 5 is facing the nozzle mounting port 451. The guide rail assembly of the inkjet printer drives the inkjet printer trolley housing 6 to move, thereby driving the inkjet printer 5 to move, and realizing the inkjet printer's inkjet printing function. When the user needs to use inkjet printer 5 of other sizes and specifications from different manufacturers, it is necessary to adjust the position and size of the inkjet printer mounting seat 45; the user controls the main screw motor 1311 to start through the external electric control system (existing technology, which will not be described here). The main screw motor 1311 drives the first double-threaded screw 131 to rotate, so that the second bevel gear 132 drives the first bevel gear 152 to rotate, and at the same time, the first bevel gear 152 at the other end of the gear connecting rod 151 drives the third bevel gear 1411 to rotate, thereby realizing the synchronous rotation of the second double-threaded screw 141, and the first slider 21 and the second slider 31 move accordingly, so that the first sliding support bar 2 and The second sliding support bar 3 slides, thereby changing the distance between the first sliding support bar 2, the second sliding support bar 3 and the fixed support bar 12. The spacing between the first sliding support bar 2 and the fixed support bar 12 is the same as the spacing between the first sliding support bar 2 and the second sliding support bar 3. At the same time, by controlling the thread shape on the first double-threaded screw rod 131 and the second double-threaded screw rod 141, the first slider 21 and the second slider 31 are moved by different distances respectively under the rotation of the first double-threaded screw rod 131 and the second double-threaded screw rod 141, that is, when the first double-threaded screw rod 131 and the second double-threaded screw rod 141 rotate at the same time, the sliding distance of the second sliding support bar 3 is twice the sliding distance of the first sliding support bar 2, so as to ensure that the distance between the fixed support bar 12 and the first sliding support bar 2 is always equal to the distance between the first sliding support bar 2 and the second sliding support bar 3, and to ensure that the nozzle mounting seat 45 set between the fixed support bar 12 and the first sliding support bar 2 and between the first sliding support bar 2 and the second sliding support bar 3 is the same size.

[0042] The user can adjust the position of the nozzle support 4 through the external electronic control system to adapt to the combination requirements of different specifications of inkjet nozzles 5. The external electronic control system controls the first screw motor 1211, the second screw motor 231 and the third screw motor 331 to start. The first screw motor 1211, the second screw motor 231 and the third screw motor 331 respectively drive the first adjusting screw 121, the second adjusting screw 23 and the third adjusting screw 33 to rotate. The moving block 42 moves under the rotation of the first adjusting screw 121, the second adjusting screw 23 and the third adjusting screw 33, and the adjusting slots 41 are connected to each other by the telescopic piece 43. When the distance between the fixed support bar 12 and the first sliding support bar 2 and the distance between the first sliding support bar 2 and the second sliding support bar 3 changes, the distance between the two adjusting slots 41 connected by the telescopic piece 43 changes accordingly. When the moving block 42 moves, the adjusting slot 41 on one side can drive the adjusting slot 41 on the other side to move synchronously through the telescopic piece 43, which is convenient for fixing the nozzle mounting base 45.

[0043] The user controls the sliding adjustment motor 4111 to start through the external electronic control system. The sliding adjustment motor 4111 can drive the third double-threaded screw rod 411 to rotate, so that the sliding support blocks 44 move closer to or away from each other. At the same time, the user manually moves the sliding support block 44 set on the fourth slide rod 412 so that the sliding support blocks 44 are respectively arranged relative to the screw fixing plate 452. According to actual usage requirements, different sizes of nozzle mounting seats 45 are selected, and the screw fixing plate 452 and the threaded hole 441 are connected by fixing screws 453 to fix nozzle mounting seats 45 of different sizes. At this time, the user takes out the inkjet nozzle 5 and installs it on the nozzle mounting seat 45. The fixed connection method of the inkjet nozzle 5 and the nozzle mounting seat 45 can adopt the existing bolt connection method. The specific connection structure and connection method are not repeated here.

[0044] In summary, by adjusting the distance between the fixed support bar 12, the first sliding support bar 2 and the second sliding support bar 3, the distance between the adjustment grooves 41 and the distance between the sliding support blocks 44, the nozzle mounting seats 45 of different sizes can be fixed, thereby achieving the technical effect of fixing the inkjet nozzles 5 of different sizes and specifications. Users do not need to replace the equipment as a whole to use inkjet nozzles 5 of different sizes and specifications produced by different manufacturers. The loading and unloading is convenient, and at the same time, the position of the inkjet nozzle 5 can be flexibly adjusted, which improves the accuracy of the inkjet printing process and has strong applicability.
