Description

Technical Field

[0001] The utility model relates to the technical field of ink path distribution devices, in particular to a three-dimensional cross ink path distribution device for a nozzle. Background Art

[0002] In inkjet printers, the discharge of the printer's nozzle is controlled by a PLC controller. Printers with multiple ink paths will use the PLC controller to control whether a certain ink path discharges material, thereby completing accurate printing.

[0003] The existing three-dimensional cross-ink distribution device for the nozzle adopts PLC to control the blocking or connection of the ink path, so that different inks are discharged through the nozzle at different times. However, in use, the ink outlet on the controller is mostly connected to the subsequent delivery pipeline by plug-in fixation, that is, the outlet is inserted into the rubber delivery pipeline, and the diameter of the outlet is used to expand the delivery pipe, and the delivery pipe will be tightly fixed to the outlet due to the non-plastic shrinkage force. In this fixing method, after the delivery pipe has been used for a long time and aged, a gap will appear at the joint with the outlet. A gap that is too large will cause the delivery pipe to fall off directly, and it will be impossible to install and deliver ink normally. Although a small gap will not cause the delivery pipe to fall off, it is very likely that the ink will leak through the gap when delivering ink, causing waste and pollution to the surrounding environment and equipment, and it will also cause the equipment to be unable to discharge materials accurately, affecting the printing quality.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a three-dimensional cross ink path distribution device for a nozzle is proposed. Utility Model Content

[0014] 1. The utility model is provided with a storage tank, a feed pipe, a protective cover and a sealing plug. Ink can be added to the storage tank through the feed pipe. After adding, the protective cover is rotated to cover and seal all the feed pipes to prevent dust from adhering.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 4 As shown, a three-dimensional cross ink path distribution device for a nozzle includes a distribution box 1, and three control discharge units 2 are evenly distributed and fixedly installed on the bottom of the inner surface of the distribution box 1. The upper ends of the control discharge units 2 are fixedly connected to a storage tank 3, and the upper end of the storage tank 3 passes through the distribution box 1 and is fixedly installed with a feed pipe 4. A protective cover 5 is rotatably installed on the upper rear side of the outer surface of the distribution box 1, and three sealing plugs 6 are evenly distributed and fixedly installed on the inner surface of the protective cover 5 to match the position of the feed pipe 4. The bottom end of the control discharge unit 2 passes through the distribution box 1 and is fixedly installed with a discharge port 7, and a fixing mechanism 8 is provided on the outside of each discharge port 7 below the outer surface of the distribution box 1; the lower front edge of the protective cover 5 is fixed to the fitting position of the distribution box 1 by magnetic sheet adsorption.

[0023] By adopting the above technical solution, ink can be added into the storage tank 3 through the feed pipe 4;

[0024] Rotate the protective cover 5 to cover and seal all the feed pipes 4 to prevent dust from adhering;

[0025] The sealing plug 6 will rotate along with the protective cover 5 to close the mouth of the feed pipe 4 and seal the storage tank 3, which can effectively prevent the ink from being contaminated by the outside world, thereby improving the protection of the ink.

[0026] Furthermore, the fixing mechanism 8 includes spring pieces 801 fixedly installed on the lower side of the outer surface of the distribution box 1 on both the left and right sides of each discharge port 7, and the spring pieces 801 are arranged to be inclined to the left and right sides.

[0027] By adopting the above technical solution, the elastic force of the spring piece 801 itself can enable the spring piece 801 to be in two states: gathered or expanded.

[0028] Furthermore, the fixing mechanism 8 also includes an arc plate 803 fixedly installed at the lower end of the spring piece 801, and the arc curve of the arc plate 803 matches the discharge port 7; the fixing mechanism 8 also includes a threaded groove 802 opened on the outer side of the surface of the spring piece 801, and the outer surface of the spring piece 801 is threadedly connected to a movable ring 804 using the threaded groove 802.

[0029] By adopting the above technical solution, the movable ring 804 is rotated and gradually moved downward along the threaded groove 802. Since the inner diameter of the movable ring 804 remains unchanged, the spring piece 801 will gradually tighten, driving the arc plate 803 to close, and using the discharge port 7 as a support point to further clamp and fix the discharge pipe from the outside.

[0030] Furthermore, the bottom end of the discharge port 7 is configured to be in the shape of an inverted cone.

[0031] By adopting the above technical solution, the discharge port 7 at the conical bottom can be better connected to the discharge pipe. The discharge pipe will gradually expand and stretch when the conical discharge port 7 is inserted, and then the elasticity of the rubber pipe will be used to fit tightly to the surface of the discharge port 7, which has stronger fit and tighter installation.

[0032] Furthermore, a distribution wiring member 9 is fixedly installed on the left side of the inner surface of the distribution box 1, and the distribution wiring member 9 is connected to each control discharge unit 2 via a transmission line; a PLC controller 10 is fixedly installed on the front side of the outer surface of the distribution box 1, and the PLC controller 10 is connected to the distribution wiring member 9 via a transmission line.

[0033] By adopting the above technical solution, the PLC controller 10 transmits the signal through the transmission line, and sends the signal to the designated control discharge unit 2 through the distribution terminal 9. The control discharge unit 2 will suck the ink in the storage tank 3 and discharge it through the discharge port 7.

[0034] After the ink is added to the ink tank 3, the protective cover 5 is rotated to cover and seal all the ink tubes 4 to prevent dust from adhering. At the same time, the sealing plug 6 closes the mouth of the feed tube 4 and seals the storage tank 3. Then, the discharge port 7 at the tapered bottom can be better connected to the discharge pipe. The discharge pipe will gradually expand and open by utilizing the tapered discharge port 7, and then, by utilizing the elasticity of the rubber pipe, it will fit tightly to the surface of the discharge port 7. Then, the movable ring 804 is rotated and gradually moves downward along the threaded groove 802. Since the inner diameter of the movable ring 804 remains unchanged, the spring piece 801 will gradually tighten, driving the arc plate 803 to close. With the discharge port 7 as the support point, the discharge pipe is further clamped and fixed from the outside, so that the ink path of the entire ink material can be connected, and the discharge work of all the control discharge units 2 is controlled by the PLC controller 10. This is the working principle of the three-dimensional cross ink path distribution device for the nozzle.
