Description

Technical Field

[0001] The present invention relates to a high-speed inkjet printer, and more particularly to a positioning side guide for a high-speed inkjet printer. Background Art

[0002] When the drive belt on the inkjet platform of a high-speed inkjet printer conveys paper, it is positioned by a positioning side guide on one side. Currently, existing positioning side guides all adopt a U-shaped structure formed by sheet metal parts and are fixed on one side of the inkjet platform through positioning pressing blocks on the platform bracket. During operation, the paper is fed into the U-shaped groove of the positioning side guide and abuts against the side guide under the combined action of the inclined drive belt and drive balls to achieve positioning. Since the U-shaped groove of the positioning side guide has a curvature, low flatness, low straightness, and a large opening size, the paper edge often warps. When the machine is running, the stability is poor, the paper edge positioning accuracy is low, resulting in low inkjet accuracy and a high defective rate. Summary of the Invention

[0003] The present invention aims to solve the above problems and thus provides a positioning side guide for a high-speed inkjet printer with high flatness, high straightness, and an adjustable opening size.

[0004] The technical solution adopted by the present invention to solve the above problems is as follows:

[0005] A positioning side guide for a high-speed inkjet printer includes a side guide steel plate provided on the inkjet printer platform, and further includes a guard plate. A positioning groove for positioning paper is provided inside the side guide steel plate, and the guard plate extends into the positioning groove. A plurality of pull plates are spaced on the upper end surface of the side guide steel plate. Each pull plate is provided with a screw mounting hole and a screw is fixedly installed through two upper and lower locking nuts. A fixing screw hole is provided at the lower end of the screw. Screw counterbores are spaced on the guard plate corresponding to the screws. The guard plate is fixedly connected to the lower end of each screw through a fixing screw. An opening for inserting paper is formed between the guard plate and the lower end plate of the positioning groove.

[0006] The present invention adopting the above technical solution, compared with the prior art, has the following prominent features:

[0007] The side guide steel plate of the present invention is processed from a whole steel plate by a machining center. The opening size between the guard plate and the lower end plate of the positioning groove is adjusted by adjusting the screw up and down, so that the opening size is suitable for papers of different thicknesses, avoiding the occurrence of paper edge warping due to too large an opening size. It has high flatness and high straightness. By reducing the opening size, it ensures that the paper edge stably abuts against the side guide positioning surface, and limits the small warping space of the paper edge, forming high-precision positioning, providing good inkjet conditions for the inkjet head of the high-speed inkjet printer, greatly improving the inkjet speed and accuracy, improving the stability during machine operation, and reducing the defective rate of the inkjet process.

[0008] As a preference, a further technical solution of the present invention is:

[0009] The positioning groove is arranged at the lower inner portion of the side gauge steel plate.

[0010] The pull plate is provided with a long positioning hole and is installed on the upper end surface of the side gauge steel plate through fixing bolts, so as to adjust the length of the guard plate extending into the positioning groove.

[0011] A locking nut yielding step is provided at the inner end of the upper end surface of the side gauge steel plate to prevent the locking nut from colliding with the side gauge steel plate when the pull plate is moved inward and outward for adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further described below in conjunction with embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6A high-speed inkjet printer positioning side gauge comprises a side gauge steel plate 1 arranged on a printer platform 9, and also comprises a guard plate 2. A positioning groove 1-1 for positioning paper is arranged on the inner side of the side gauge steel plate 1, and the guard plate 2 extends into the positioning groove 1-1. A plurality of pull plates 4 are arranged at intervals on the upper end surface of the side gauge steel plate 1. Each pull plate 4 is provided with a screw mounting hole and a screw 3 is fixedly installed thereon through two upper and lower locking nuts 6. A fixing screw hole is arranged at the lower end of the screw 3. Screw countersunk holes are arranged at intervals on the guard plate 2 corresponding to the screw 3. The guard plate 2 is fixedly connected to the lower end of each screw 3 by a fixing screw 7, and an opening for extending into the paper is formed between the guard plate 2 and the lower end plate 1-2 of the positioning groove.

[0021] The positioning groove 1-1 is arranged at the inner lower position of the side gauge steel plate 1, so that the thickness of the lower end plate 1-2 of the positioning groove is thin enough. In this embodiment, the thickness of the lower end plate 1-2 of the positioning groove is 1.5 mm. The side gauge steel plate 1 is made of high-quality carbon structural steel plate. The positioning groove 1-1 is integrally processed by a machining center, and the guard plate 2 is made of a 2 mm thick strip plate.

[0022] The pull plate 4 is provided with a long positioning hole and is mounted on the upper end surface of the side gauge steel plate 1 through a fixing bolt 5, so as to adjust the length of the guard plate 2 extending into the positioning groove 1-1.

[0023] A locking nut clearance step 8 is provided at the inner end of the upper end surface of the side gauge steel plate 1 to prevent the locking nut 6 from colliding with the side gauge steel plate 1 when the pull plate 4 is moved inward and outward for adjustment.

[0024] The side gauge steel plate of the present invention is made of a whole steel plate processed by a machining center. The opening size between the guard plate 2 and the lower end plate 1-2 of the positioning groove is adjusted by adjusting the screw rod 3 up and down, so that the opening size is suitable for papers of different thicknesses, avoiding the warping of the paper edge caused by the opening size being too large. The flatness and straightness are high. By reducing the opening size, the paper edge is ensured to be stably against the side specified position plane, and the warping space of the paper edge is limited to be small, so as to form high-precision positioning, provide good inkjet conditions for the high-speed inkjet printer nozzle, greatly improve the speed and accuracy of inkjet coding, improve the stability of the machine during operation, and reduce the scrap rate of the inkjet coding process.

[0025] The above description is only a preferred feasible embodiment of the present invention, and does not limit the scope of rights of the present invention. All equivalent changes made using the contents of the present specification and its drawings are included in the scope of rights of the present invention.
