Description

Technical Field

[0001] The utility model relates to the technical field of ink jet printers, in particular to a continuous ink jet printer. Background Art

[0002] The inkjet printer is a non-contact inkjet marking system controlled by a single-chip microcomputer. It applies a certain pressure to the ink in the system by controlling the internal gear pump or supplying compressed gas from the outside of the machine, so that the ink is ejected through a nozzle with an aperture of tens of microns. The crystal oscillation signal applied above the nozzle splits the ejected continuous ink line into ink droplets of the same frequency, equal size and a certain spacing.

[0003] When the existing continuous ink jet printer is in use, when it is coding on different materials, the ink sometimes splashes, affecting the progress of the coding work and affecting the hygiene of the surrounding area. In addition, when general ink jet printers are coding on different positions, they often need to rotate the support rod to facilitate coding on different positions. The rotation of the support rod is inconvenient, and long-term rotation can easily cause greater friction between it and the ground, affecting the service life of the support rod, and the practicality is low.

[0004] For example, a continuous inkjet printer disclosed in Chinese patent CN214492108U has a support column, a connecting column is connected to the top of the support column, and a first slide groove is connected to one side of the connecting column, a first slider is inserted into the internal sleeve of the first slide groove, and a connecting plate is fixedly connected to one side of the first slider, a second slide groove is inserted into one side of the connecting plate, and a second slider is inserted into the internal sleeve of the second slide groove. In the utility model, the baffle plate and the connecting rod are movably connected, so that the baffle plate can be flipped, and the limit block connected to one side of the baffle plate can be flipped to the inside of the limit groove, so that the two baffle plates can be restricted to the two sides of the nozzle, so as to prevent the nozzle from splashing ink when printing on objects of different materials, which affects the progress of the printing work and the subsequent use of the object. The first reset spring is convenient for resetting the baffle plate, so that one side of the baffle plate contacts the bottom end of the connecting plate, so as to facilitate its storage.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 , the utility model provides a technical solution: Embodiment 1:

[0027] A continuous ink jet printer comprises a conveyor belt 1, wherein an adjusting ink jet structure is installed at the left end of the top surface of the conveyor belt 1, a clamping structure is installed at the bottom of the adjusting ink jet structure, and a drying structure is installed at the right end of the top surface of the conveyor belt 1.

[0028] The coding adjustment structure includes an adjustment unit and an installation connection unit. The adjustment unit includes an asynchronous motor 102, a threaded rod 103 is connected to the output end of the asynchronous motor 102, a sleeve 106 is connected to the outer surface of the threaded rod 103, a slider 107 is installed on the outer surface of the sleeve 106, a hydraulic cylinder 108 is installed on the bottom surface of the slider 107, a telescopic rod 109 is installed in the middle of the bottom surface of the hydraulic cylinder 108, and a coding machine 110 is installed at the bottom end of the telescopic rod 109. The installation connection unit includes a mounting plate 101, a bearing 104 is arranged on the back of the mounting plate 101, and a positioning plate 105 is installed on the outer surface of the bearing 104.

[0029] The top surface of the mounting plate 101 is detachably connected to the bottom surface of the asynchronous motor 102 , and the inside of the bearing 104 is fixedly connected to the non-threaded portion of the front and back ends of the outer surface of the threaded rod 103 .

[0030] By setting the adjustment structure, the asynchronous motor 102 can be used to drive the threaded rod 103 to rotate. When the threaded rod 103 rotates, the sleeve 106 drives the slider 107 to move, thereby driving the hydraulic cylinder 108, the telescopic rod 109, and the inkjet printer 110 to move. The height of the inkjet printer 110 can be effectively adjusted by using the hydraulic cylinder 108 and the telescopic rod 109, so that the inkjet printer 110 can be more flexible in coding.

[0031] When the inkjet printer 110 is used for inkjet coding, the threaded rod 103 is driven to rotate by starting the asynchronous motor 102. The threaded rod 103 is connected to the sleeve 106 by thread. When the threaded rod 103 rotates, the sleeve 106 is displaced. As a result, the sleeve 106 drives the slider 107 to be displaced when it moves. The inkjet printer 110 can be adjusted in the horizontal direction. At the same time, the telescopic rod 109 is driven to extend or shorten by the hydraulic cylinder 108, which can drive the inkjet printer 110 to rise and fall.

[0034] By setting up the clamping structure and the drying structure, the hydraulic cylinder 203 can be used to drive the telescopic rod 202 to extend, so that the two clamping plates 205 can be brought close to each other, and the items to be coded can be clamped and fixed to facilitate accurate coding. After coding, the fan 302 can be rotated to blow the heat of the heating tube 304, so that the coding can be dried quickly, which is convenient for storing and transporting the items after coding, and there will be no smudged codes.

[0035] After the items are coded by the inkjet printer 110, the items are conveyed by the conveyor belt 1, and can be conveyed to the bottom of the drying rack 301. By turning on the heating tube 304 for heating, the temperature inside the drying box 303 can be increased. Then, the fan 302 can be turned on to blow hot air to the items on the top surface of the conveyor belt 1 after the coding, so that the coding on the top surface of the items can be quickly dried, which is convenient for the subsequent transportation and storage of the items without the phenomenon of blurred codes.
