Description

Technical Field

The conveyor belt is easily contaminated with dust during the production process, causing slippage between the encoder synchronous wheel and the conveyor belt, resulting in positioning errors. Third, the processing accuracy of the encoder synchronous wheel is limited, resulting in positioning errors. In addition, there is also a problem of poor accuracy when positioning the nozzle position. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In this article, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0020] In the prior art, when the conveyor belt material is different, the friction force is also different, resulting in deviations in the readings of the printed material and the encoder. The conveyor belt is easily contaminated with dust during the production process, resulting in slippage between the encoder synchronous wheel and the conveyor belt, resulting in positioning errors. Third, the processing accuracy of the encoder synchronous wheel is limited, resulting in positioning errors. In addition, there is also a problem of poor accuracy when positioning the nozzle position. The embodiment of the present invention provides the following solution: like Figures 1 to 3As shown, an embodiment of the present invention provides a single-pass printer, including a conveying mechanism 1 and a print head mechanism 2. The conveying mechanism 1 is provided with a conveying belt 11 and a first grating reader 12. A first grating strip 13 corresponding to the first grating reader 12 is provided on one side of the conveying belt 11. The print head mechanism 2 is provided with a liftable print head 21, a traverse belt 22, and a second grating reader 23. The print head 21 is connected to the traverse belt 22. A distance sensor 24 is provided on one side of the print head 21, and a second grating strip 25 corresponding to the second grating reader 23 is provided on one side of the traverse belt 22.

[0021] It should be noted that during the printing operation, the printing consumables move with the movement of the conveyor belt 11, and the printing consumables can be printing paper heads. During the movement, the moving position of the first grating strip 13 is continuously read by the first grating reader 12, and the first grating strip 13 and the first grating reader 12 are non-contact, so that the error caused by mechanical processing can be eliminated, and the specific position of the printing consumables can be obtained more accurately, thereby generating a more accurate positioning signal for the nozzle printing. During the printing process, the nozzle 21 moves with the movement of the transverse belt 22. During the movement, the moving position of the second grating strip 13 is continuously read by the second grating reader 12, so that the position of the nozzle 21 can be accurately located. At the same time, the distance sensor 24 can also detect the distance between the nozzle 21 and the printing consumables, so as to adjust the nozzle 21 to the most suitable position for printing, further improving the printing quality.

[0022] In some embodiments, the conveying mechanism 1 includes a rotatable roller 14 and a roller connecting plate 15, and both ends of the roller 14 are rotatably connected to the roller connecting plate 15. The conveyor belt 11 is mounted on the roller 14, and the first grating reader 12 is mounted on the outer side of the roller connecting plate 15. It can be understood that the rotation of the roller 14 drives the movement of the conveyor belt 11, thereby driving the movement of the printing consumables.

[0023] In some embodiments, the conveying mechanism 1 further includes a driving motor, the motor shaft of the driving motor is connected to one end of the roller 14, and the rotation of the driving motor drives the roller 14 to rotate.

[0024] In some embodiments, the print head mechanism 2 includes a support frame 26, a traverse seat 27, a first guide shaft 28, a second guide shaft 29 and a lifting device 3, wherein the support frame 26 is mounted on the roller connecting plate 15, the two ends of the first guide shaft 28 are respectively connected to the two sides of the support frame 26, and the two ends of the second guide shaft 29 are respectively connected to the two sides of the support frame 26. The traverse seat 27 is provided with a guide sliding hole adapted to the first guide shaft 28 and the second guide shaft 29, and the traverse seat 27 is connected to the traverse belt 22. The lifting device 3 is connected to the bottom of the traverse seat 27, and the lifting end of the lifting device 3 is connected to the nozzle 21.

[0025] It should be noted that during the printing process, when the transverse shift seat 27 moves with the movement of the transverse shift belt 22, the transverse shift seat 27 is guided and moved by the first guide shaft 28 and the second guide shaft 29, thereby increasing the lateral movement accuracy of the transverse shift seat 27, thereby increasing the movement accuracy of the nozzle 21 and further improving the printing quality.

[0026] In some embodiments, the support frame 26 includes a lateral support 261 and a transverse support 262. The lateral support 261 is vertically arranged, and the lateral support 261 is respectively connected to the two ends of the transverse support 262. The bottom of the lateral support 261 is connected to the roller connecting plate 15, thereby simplifying the structural complexity of the entire printer and reducing the manufacturing cost.

[0027] In some embodiments, the lateral shifting belt 22 is a synchronous belt, and the lateral bracket 261 is provided with a synchronous pulley seat 221, and a rotatable synchronous pulley 222 is provided in the synchronous pulley seat 221, and the lateral shifting belt 22 is meshedly connected with the synchronous pulley 222. A driving motor is installed on one side of the synchronous pulley seat 221, and the motor shaft of the driving motor is connected to the synchronous pulley 222. It can be understood that when the driving motor rotates, the synchronous pulley is driven to rotate, thereby driving the lateral shifting belt 22 to move.

[0028] In some embodiments, the transverse shift seat 27 is provided with a hollow body 271, and the transverse shift belt 22 passes through the hollow body 271 and is connected to the top of the hollow body 271, thereby reducing the weight of the transverse shift seat 27 and reducing the structural complexity.

[0029] In some embodiments, the lifting device 3 is an electric telescopic rod, and the lifting and lowering of the spray head 21 is driven by the lifting and lowering of the electric telescopic rod.

[0030] In some embodiments, the distance measuring sensor 24 is installed on a bottom side of the traverse seat 27 .

[0031] In some embodiments, the first guide shaft 28 and the second guide shaft 29 are both linear shafts, and linear bearings are provided in the guide sliding holes, thereby further improving the accuracy of the transverse shift seat 27 during the movement process.

[0032] In summary, an embodiment of the present invention provides a single-pass printer, in which a grating strip is arranged on one side of a conveyor belt, and the position of the conveyor belt is located by a grating reader, thereby improving the accuracy of positioning the printing consumables through non-contact measurement and positioning. At the same time, a grating strip is arranged on one side of a transverse belt for laterally moving a print head, and the position of the print head is located by a grating reader, thereby greatly improving the positioning accuracy of the print head. The distance measuring sensor arranged on one side of the print head can detect the thickness of the printing consumables, so that the position of the print head can be optimized and adjusted, thereby further improving the printing quality.
