Description

Technical Field

[0001] The present invention belongs to the technical field of inkjet printer nozzles, and specifically refers to a fixed structure for the movement of an inkjet printer nozzle. Background Art

[0002] As the core execution component of digital inkjet equipment, the inkjet printer nozzle is mainly used to convert electronic signals into precise jets of ink droplets, achieving high-quality output of images, texts, or patterns on the surfaces of flexible or rigid media such as advertising light box cloth, vehicle body films, and building decoration materials. Its technical performance directly determines the inkjet accuracy, color reproduction, production efficiency, and equipment reliability, and it is a key technical unit in fields such as advertising inkjet, industrial printing, and textile digital printing.

[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 the nozzle, they may need to replace the entire device, resulting in high costs. Fixed installation may make it difficult to disassemble during maintenance. Especially in a multi-nozzle array, when a single nozzle is damaged, the entire module may need to be removed, affecting efficiency. Fixed installation may not be able to dynamically adjust the nozzle spacing. When the nozzle position shifts after long-term use, it cannot be automatically calibrated, resulting in splicing errors and affecting the pattern quality. Summary of the Invention

[0004] The present invention overcomes the deficiencies of the prior art and provides a fixed structure for the movement of an inkjet printer nozzle. The main lead screw motor drives the first double-threaded lead screw to rotate, causing the second bevel gear to drive 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, achieving the synchronous rotation of the second double-threaded lead screw. The first sliding support bar and the second sliding support bar slide respectively under the rotation of the first double-threaded lead screw and the second double-threaded lead 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 lead screw motor, the second lead screw motor, and the third lead screw motor drive the first adjustment lead screw, the second adjustment lead screw, and the third adjustment lead screw to rotate respectively, thereby causing the nozzle support member to slide. The sliding adjustment motor drives the third double-threaded lead screw to rotate, 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 flexibly fixing inkjet nozzles of different sizes.

[0005] The technical solution adopted by the present invention is as follows: This solution provides a fixed structure for the movement of the inkjet printer nozzle, including a support bottom plate. A regulation opening is provided at the center of the upper wall of the support bottom plate. A fixed support bar is fixedly provided at the middle part of the support bottom plate. First sliding support bars are symmetrically and slidably provided on both the left and right sides of the fixed support bar. Second sliding support bars are slidably provided on the sides of the first sliding support bars away from the fixed support bar. Nozzle support members are slidably arranged along the length direction of the fixed support bar between the first sliding support bar and the second sliding support bar and between the first sliding support bar and the fixed support bar. An inkjet printer nozzle is movably clamped on the nozzle support member.

[0006] Further, first screw rod grooves and second screw rod grooves are respectively provided at the front and rear edges of the upper wall of the support bottom plate. The first screw rod groove and the second screw rod groove are respectively arranged on the front and rear sides of the regulation opening. A first double-threaded screw rod is rotatably provided in the first screw rod groove, and a second double-threaded screw rod is rotatably provided in the second screw rod groove. A gear groove perpendicular to the first screw rod groove and the second screw rod groove is provided at the edge of the upper wall of the support bottom plate. A gear connecting rod is rotatably provided in the gear groove. First bevel gears are coaxially fixed at both ends of the gear connecting rod. A second bevel gear is coaxially fixed at the end of the first double-threaded screw rod. The second bevel gear meshes with one of the first bevel gears. A third bevel gear is coaxially fixed at the end of the second double-threaded screw rod. The third bevel gear meshes with the other first bevel gear. A main screw rod motor is fixedly provided on the side wall at the end of the first screw rod groove. The output end of the main screw rod motor is connected to the first double-threaded screw rod.

[0007] Further, first sliding grooves and second sliding grooves are respectively provided at the front and rear edges of the upper wall of the support bottom plate. The first sliding groove and the second sliding groove are respectively located on the front and rear sides of the regulation opening. The first sliding groove and the second sliding groove are respectively arranged close to the second screw rod groove and the first screw rod groove.

[0008] Further, first sliders and first clamping blocks are respectively fixed at both ends of the first sliding support bar. The first sliders are clamped and slid in the first screw rod groove. The first sliders are sleeved on the first double-threaded screw rod. The first sliders are respectively connected to the reverse threads at both ends of the first double-threaded screw rod. The first clamping blocks are clamped and slid in the first sliding groove. Second sliders and second clamping blocks are respectively fixed at both ends of the second sliding support bar. The second sliders are clamped and slid in the second screw rod groove. The second sliders are sleeved on the second double-threaded screw rod. The second sliders are connected to the reverse threads at both ends of the second double-threaded screw rod. The second clamping blocks are clamped and slid in the second sliding groove.

[0009] Furthermore, the spacing between the fixed support bar and the first sliding support bar, and between the first sliding support bar and the second sliding support bar is the same. When the first double-threaded lead screw and the second double-threaded lead screw rotate synchronously, the first sliding support bars on the same side of the fixed support bar move in the same direction, and the moving distance of the second sliding support bar is twice that of the first sliding support bar.

[0010] Furthermore, the upper wall of the fixed support bar is symmetrically provided with a first adjusting lead screw and a first sliding rod. The first adjusting lead screw is driven by a first lead screw motor disposed inside the fixed support bar. The upper wall of the first sliding support bar is symmetrically provided with a second adjusting lead screw and a second sliding rod. The second adjusting lead screw is driven by a second lead screw motor disposed inside the first sliding support bar. The upper wall of the second sliding support bar is respectively provided with a third adjusting lead screw and a third sliding rod. The third adjusting lead screw is driven by a third lead screw motor disposed inside the second sliding support bar. The first adjusting lead screw, the first sliding rod, the second adjusting lead screw, the second sliding rod, the third adjusting lead screw and the third sliding rod are arranged symmetrically and adjacently.

[0011] Furthermore, the nozzle support member includes an adjustment groove, a moving block and a telescopic piece. The adjustment grooves are symmetrically disposed between the fixed support bar and the first sliding support bar, and between the first sliding support bar and the second sliding support bar; the moving block is fixed to the middle of the adjustment groove. The moving block is sleeved on the third sliding rod, the second adjusting lead screw, the second sliding rod, the first adjusting lead screw, the first sliding rod and the third adjusting lead screw. The moving block is respectively threadedly connected to the first adjusting lead screw, the second adjusting lead screw and the third adjusting lead screw. The two ends of the adjustment groove are fixed with telescopic pieces, and are snap-fitted and slidably connected to the telescopic pieces on the adjustment groove.

[0012] Furthermore, a third double-threaded lead screw and a fourth sliding rod are respectively disposed in the adjustment groove. The third double-threaded lead screw is driven by a sliding adjustment motor disposed at the end of the adjustment groove. A pair of sliding support blocks are sleeved on the third double-threaded lead screw and the fourth sliding rod. The sliding support blocks are reversely threadedly connected to both ends of the third double-threaded lead screw. A threaded hole is provided on the upper wall of the sliding support block, and the threaded hole is used for installing a nozzle mounting seat. Four corners of the nozzle mounting seat are provided with screw fixing pieces, and the screw fixing pieces are connected to the threaded holes through fixing screws. A nozzle mounting opening is provided in the middle of the nozzle mounting seat.

[0013] Furthermore, the inkjet nozzle is snap-fitted and fixed in the nozzle mounting opening. The edge of the upper wall of the support bottom plate is enclosed with a nozzle carriage housing. Inkjet ink bottles are arrayed and fixed at the upper end inside the nozzle carriage housing. The inkjet ink bottles are connected to the inkjet nozzle through nozzle ink tubes.

[0014] Furthermore, the first lead screw motor, the main lead screw motor, the second lead screw motor, the third lead screw motor and the sliding adjustment motor are all electrically connected to an external electronic control system.

[0015] The beneficial effects achieved by the present invention with the above structure are as follows: (1) The main lead screw motor drives the first double-threaded lead screw to rotate, causing the second bevel gear to drive 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, realizing the synchronous rotation of the second double-threaded lead screw. The first sliding support bar and the second sliding support bar slide respectively under the rotation of the first double-threaded lead screw and the second double-threaded lead screw, thereby changing the distance between the first sliding support bar, the second sliding support bar and the fixed support bar. The distance between the first sliding support bar and the fixed support bar is the same as the distance between the first sliding support bar and the second sliding support bar. At the same time, by controlling the thread shapes on the first double-threaded lead screw and the second double-threaded lead screw, the first slider and the second slider move different distances respectively under the rotation of the first double-threaded lead screw and the second double-threaded lead screw. That is, when the first double-threaded lead screw and the second double-threaded lead screw rotate simultaneously, the sliding distance of the second sliding support bar is twice the sliding distance of the first sliding support bar, so as to ensure that the distance between the fixed support bar and the first sliding support bar is always equal to the distance between the first sliding support bar and the second sliding support bar; (2) The first lead screw motor, the second lead screw motor and the third lead screw motor drive the first adjusting lead screw, the second adjusting lead screw and the third adjusting lead screw to rotate respectively. The moving block moves under the rotation of the first adjusting lead screw, the second adjusting lead screw and the third adjusting lead screw. The adjusting grooves are connected to each other through the telescopic pieces. When the distance between the fixed support bar and the first sliding support bar and the distance between the first sliding support bar and the second sliding support bar change, the distance between the two adjusting grooves connected by the telescopic pieces changes accordingly. When the moving block moves, one adjusting groove can drive the other adjusting groove to move synchronously through the telescopic piece, thereby adjusting the position of the nozzle mounting seat; (3) The sliding adjustment motor can drive the third double-threaded lead screw to rotate, so that the sliding support blocks approach or move away from each other. Select nozzle mounting seats of different sizes according to actual usage requirements. Connect the screw fixing piece and the threaded hole through the fixing screw, which serves to fix the nozzle mounting seats of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

A third bevel gear 1411 is coaxially fixed at the end of the second double-threaded lead screw 141. The third bevel gear 1411 meshes with the other first bevel gear 152. A main lead screw motor 1311 is fixed on the side wall at the end of the first lead screw groove 13. The output end of the main lead screw motor 1311 is connected to the first double-threaded lead screw 131.

[0022] The front and rear edges of the upper wall of the support base plate 1 are respectively provided with a first sliding groove 16 and a second sliding groove 17. The first sliding groove 16 and the second sliding groove 17 are respectively located on the front and rear sides of the adjustment opening 11. The first sliding groove 16 and the second sliding groove 17 are respectively arranged close to the second lead screw groove 14 and the first lead screw groove 13.

[0023] Both ends of the first sliding support bar 2 are respectively fixed with a first slider 21 and a first clamping block 22. The first slider 21 is clamped and slides in the first lead screw groove 13. The first slider 21 is sleeved on the first double-threaded lead screw 131. The first slider 21 is respectively connected to the two ends of the first double-threaded lead screw 131 by reverse threads. The first clamping block 22 is clamped and slides in the first chute 16. Both ends of the second sliding support bar 3 are respectively fixed with a second slider 31 and a second clamping block 32. The second slider 31 is clamped and slides in the second lead screw groove 14. The second slider 31 is sleeved on the second double-threaded lead screw 141. The second slider 31 is connected to the two ends of the second double-threaded lead screw 141 by reverse threads. The second clamping block 32 is clamped and slides in the second chute 17.

[0024] The distance 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. When the first double-threaded lead screw 131 and the second double-threaded lead screw 141 rotate synchronously, the first sliding support bar 2 and the first sliding support bar 2 on the same side of the fixed support bar 12 move in the same direction, and the moving distance of the second sliding support bar 3 is twice that of the first sliding support bar 2.

[0025] On the upper wall of the fixed support bar 12, a first adjusting lead screw 121 and a first sliding rod 122 are symmetrically arranged. The first adjusting lead screw 121 is driven by a first lead screw motor 1211 arranged in the fixed support bar 12. On the upper wall of the first sliding support bar 2, a second adjusting lead screw 23 and a second sliding rod 24 are symmetrically arranged. The second adjusting lead screw 23 is driven by a second lead screw motor 231 arranged inside the first sliding support bar 2. On the upper wall of the second sliding support bar 3, a third adjusting lead screw 33 and a third sliding rod 34 are respectively arranged. The third adjusting lead screw 33 is driven by a third lead screw motor 331 arranged inside the second sliding support bar 3. The first adjusting lead screw 121, the first sliding rod 122, the second adjusting lead screw 23, the second sliding rod 24, the third adjusting lead screw 33 and the third sliding rod 34 are symmetrically and adjacently arranged.

[0026] The nozzle support member 4 includes an adjusting groove 41, a moving block 42 and a telescopic piece 43. The adjusting grooves 41 are symmetrically arranged 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. The moving block 42 is fixed in the middle of the adjusting groove 41. The moving block 42 is sleeved on the third sliding rod 34, the second adjusting lead screw 23, the second sliding rod 24, the first adjusting lead screw 121, the first sliding rod 122 and the third adjusting lead screw 33. The moving block 42 is respectively threadedly connected to the first adjusting lead screw 121, the second adjusting lead screw 23 and the third adjusting lead screw 33. Both ends of the adjusting groove 41 are fixed with telescopic pieces 43, and the telescopic pieces 43 on the opposite adjusting grooves 41 are clamped and slidably connected.

[0027] A third double-threaded lead screw 411 and a fourth slide bar 412 are respectively arranged in the adjustment groove 41. The third double-threaded lead screw 411 is driven by a sliding adjustment motor 4111 arranged at the end of the adjustment groove 41. Sliding support blocks 44 are sleeved in pairs on the third double-threaded lead screw 411 and the fourth slide bar 412. The sliding support blocks 44 are threadedly connected to the two ends of the third double-threaded lead screw 411 in opposite directions. A threaded hole 441 is formed in the upper wall of the sliding support block 44. The threaded hole 441 is used for installing a nozzle mounting seat 45. Four corners of the nozzle mounting seat 45 are provided with screw fixing pieces 452. The screw fixing pieces 452 are connected to the threaded hole 441 through fixing screws 453. A nozzle mounting opening 451 is formed in the middle of the nozzle mounting seat 45. The inkjet nozzle 5 is snap-fitted and fixed in the nozzle mounting opening 451.

[0028] The first lead screw motor 1211, the main lead screw motor 1311, the second lead screw motor 231, the third lead screw motor 331, and the sliding adjustment motor 4111 are all electrically connected to an external electric control system.

[0029] Working principle and working process: The user selects a spray nozzle 5 of a suitable specification according to the actual situation. Generally, the user can fix the spray nozzle 5 on the nozzle mounting seat 45. The lower nozzle of the spray nozzle 5 faces the nozzle mounting opening 451. The guide rail assembly of the inkjet printer drives the movement of the nozzle carriage housing 6, thereby driving the movement of the spray nozzle 5 to achieve the inkjet function of the inkjet printer. When the user needs to use spray nozzles 5 of other size specifications from different manufacturers, it is necessary to adjust the position and size of the nozzle mounting seat 45. The user controls the main lead screw motor 1311 to start through an external electric control system (prior art, not described here). The main lead screw motor 1311 drives the first double-threaded lead screw 131 to rotate, causing the second bevel gear 132 to drive the first bevel gear 152 to rotate. At the same time, the first bevel gear 152 at the other end of the gear link 151 drives the third bevel gear 1411 to rotate, realizing the synchronous rotation of the second double-threaded lead screw 141. The first slider 21 and the second slider 31 move accordingly, causing the first sliding support bar 2 and the second sliding support bar 3 to slide, and further changing the distance between the first sliding support bar 2, the second sliding support bar 3 and the fixed support bar 12. The distance between the first sliding support bar 2 and the fixed support bar 12 is the same as the distance between the first sliding support bar 2 and the second sliding support bar 3. At the same time, by controlling the thread shapes on the first double-threaded lead screw 131 and the second double-threaded lead screw 141, the first slider 21 and the second slider 31 move different distances when the first double-threaded lead screw 131 and the second double-threaded lead screw 141 rotate. That is, when the first double-threaded lead screw 131 and the second double-threaded lead screw 141 rotate simultaneously, 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, ensuring that the sizes of the nozzle mounting seats 45 provided 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 are the same.

[0030] The user can adjust the position of the nozzle support 4 through the external electric control system to adapt to the combination requirements of different specifications of inkjet nozzles 5. The external electric 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 grooves 41 are connected to each other through 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 grooves 41 connected by the telescopic piece 43 changes accordingly. When the moving block 42 moves, the adjusting groove 41 on one side can drive the adjusting groove 41 on the other side to move synchronously through the telescopic piece 43, so as to facilitate the fixing of the nozzle mounting seat 45.

[0031] The user controls the sliding adjustment motor 4111 to start through the external electric control system, and the sliding adjustment motor 4111 can drive the third double-threaded screw rod 411 to rotate, so that the sliding support blocks 44 are moved closer to or farther away from each other. At the same time, the user manually moves the sliding support block 44 arranged on the fourth slide rod 412, so that the sliding support block 44 is respectively arranged relative to the screw fixing plate 452. According to actual use requirements, nozzle mounting seats 45 of different sizes are selected, and the screw fixing plate 452 and the threaded hole 441 are connected by fixing screws 453, so as 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 between the inkjet nozzle 5 and the nozzle mounting seat 45 can adopt the existing bolt connection method, and the specific connection structure and connection method are not repeated here.

[0032] 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 entire equipment to use the 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.

[0034] The above description of the present invention and its embodiments is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural forms and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
