Description

Technical Field

[0001] The utility model relates to the technical field of inkjet equipment, and specifically to an adjustable inkjet head and an inkjet device. Background Art

[0002] In the domestic military and civilian aircraft manufacturing industry, for example, during the assembly process of fixed-wing business jet components, helicopter components, and internal components of medium and large UAVs, component marking is performed. In the current component marking process, inkjet marking is required on both sides of components that are perpendicular to each other or on both sides of angles at different angles.

[0003] The current technical means to achieve the above-mentioned inkjet marking is to use a mechanical inkjet method to complete the inkjet marking on one side, and then adjust the posture of the entire inkjet device to perform the inkjet marking on the other side. When the angle of one inkjet end cannot be satisfied, it is necessary to replace the nozzle with a suitable angle according to the size of the spatial position, resulting in low construction efficiency and increased equipment costs. Utility Model Content

[0004] In order to overcome the problem of low construction efficiency when performing inkjet marking on both sides of different angles, the utility model provides an adjustable inkjet head and an inkjet device.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0007] In the present application, the inkjet head is configured such that the main structure is a vector nozzle structure, and the telescopic inkjet tube running through the vector nozzle structure is bent at a certain angle through relative rotation between adjacent nozzle units in the vector nozzle structure, thereby adjusting the inkjet direction.

[0008] In some embodiments, the vector nozzle structure is a three-bearing vector nozzle structure, consisting of a first nozzle unit, a second nozzle unit and a third nozzle unit; the front end face and the end end face of the second nozzle unit are symmetrically arranged relative to the cross section of the second nozzle unit.

[0009] In this embodiment, the telescopic inkjet tube is bent inside the vector nozzle structure, and while ensuring that the implementation is relatively simple and convenient, it is preferably implemented as above.

[0010] Furthermore, the first nozzle unit, the second nozzle unit and the third nozzle unit are all tubular structures with elliptical cross-sections, and the terminal end face of the first nozzle unit, the front end face and the terminal end face of the second nozzle unit, and the front end face of the third nozzle unit are all circular.

[0011] In this embodiment, the above implementation makes processing easy, the overall structure is more complete, and the rotation between adjacent nozzle units is easier to achieve.

[0012] Furthermore, the angle between the front end surface of the second nozzle unit and the center axis of the second nozzle section unit is greater than or equal to 22.5°.

[0013] In this embodiment, the above angle is limited to be greater than or equal to 22.5°, combined with the aforementioned symmetrical arrangement of the front end face and the terminal end face of the second nozzle unit relative to the cross section of the second nozzle unit, combined with the aforementioned mutual adaptation of the inclined surface structure between the two adjacent nozzle units, it can be obtained that: the angle between the rear end face of the first nozzle unit and the central axis of the first nozzle unit is greater than or equal to 22.5°, the angle between the rear end face of the second nozzle unit and the central axis of the second nozzle unit is greater than or equal to 22.5°, and the angle between the front end face of the third nozzle unit and the central axis of the third nozzle is greater than or equal to 22.5°. As implemented above, the maximum deflection state of the three-bearing vector nozzle structure can achieve an inkjet angle adjustment of greater than or equal to 90°.

[0014] Furthermore, the angle between the front end surface of the second nozzle unit and the center axis of the second nozzle unit is equal to 22.5°.

[0015] In this embodiment, the aforementioned angle is preferably 22.5°, which can achieve a maximum adjustment of the inkjet angle to 90°, and can meet the current requirements for inkjet marking.

[0016] In some embodiments, the nozzle connection mechanism includes a rotating gear and a driving motor; a rotating gear is fixedly provided at the front end of the second nozzle unit, and a driving motor is correspondingly provided on the first nozzle unit; a rotating gear is fixedly provided at the front end of the third nozzle unit, and a driving motor is correspondingly provided on the second nozzle unit.

[0017] In this embodiment, it is preferably implemented as above, and the control connection and drive structure are simple and easy to implement.

[0018] Furthermore, the driving motor is a servo motor.

[0019] In this embodiment, considering that the driving motor is used for adjusting the rotation angle between adjacent nozzle structures, a servo motor is preferably used.

[0020] In some embodiments, the telescopic inkjet tube is located on one side of the end of the vector nozzle structure and is fixedly connected to the vector nozzle structure.

[0021] In this embodiment, one end of the telescopic inkjet tube for spraying ink is fixedly connected to the vector nozzle structure to provide a relatively stable inkjet effect before and after rotation.

[0022] The utility model also provides an inkjet device, comprising the adjustable inkjet head described in any one of the above embodiments, and a telescopic inkjet tube is connected to an ink supply unit in the inkjet device.

[0023] The beneficial effects of the utility model are:

[0024] 1. The inkjet head is configured with a main structure of a vector nozzle structure. Through the relative rotation between adjacent nozzle units in the vector nozzle structure, the telescopic inkjet tube running through the inside is bent at a certain angle, thereby adjusting the inkjet direction, thereby facilitating the adjustment of the inkjet direction and improving construction efficiency.

[0025] 2. Taking into account the bending of the telescopic inkjet tube and the ease of implementation, a three-bearing vector nozzle structure is selected; the angle between each inclined surface structure and the central axis of the nozzle unit in which it is located is 22.5°, so that the maximum adjustment angle is 90°.

[0031] The utility model is further described below in conjunction with the accompanying drawings.

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] like Figure 1-3 As shown, the utility model provides an adjustable inkjet head.

[0034] The adjustable inkjet head comprises a vector nozzle structure composed of a plurality of nozzle units connected in sequence, wherein two adjacent nozzle units have mutually adaptable inclined structures and are connected through a nozzle connecting mechanism, and adjacent nozzle units can achieve relative rotation after connection; the head also comprises a telescopic inkjet tube 4, which runs through the vector nozzle structure; the rotation of the vector inkjet structure drives the change of the inkjet direction.

[0035] In the present application, the inkjet head is configured such that the main structure is a vector nozzle structure, and the telescopic inkjet tube 4 running through the vector nozzle structure is bent at a certain angle through relative rotation between adjacent nozzle units in the vector nozzle structure, thereby adjusting the inkjet direction.

[0036] There are multiple implementations of the nozzle connection structure here, as shown in the Chinese patent texts with publication numbers CN110641695B, CN205872443U, CN219445102U, and CN109505708B.

[0037] Obviously, based on the aforementioned public texts, the vector nozzle structure and the three-bearing vector nozzle structure are both technical terms known in the art.

[0038] In this embodiment, based on the fact that the telescopic inkjet tube 4 will be bent inside the vector nozzle structure, while ensuring that the implementation is relatively simple and convenient, the preferred vector nozzle structure is a three-bearing vector nozzle structure, which is composed of a first nozzle unit 1, a second nozzle unit 2 and a third nozzle unit 3; the front end face and the end end face of the second nozzle unit 2 are symmetrically arranged relative to the cross-section of the second nozzle unit 2.

[0039] Obviously, the symmetrical arrangement of the front end face and the rear end face of the second nozzle unit 2 is based on a symmetrical arrangement of a certain cross section of the second nozzle unit 2, but is not symmetrical with respect to any cross section of the second nozzle unit 2.

[0040] Furthermore, the first nozzle unit 1, the second nozzle unit 2 and the third nozzle unit 3 are all tubular structures with elliptical cross-sections, and the terminal end face of the first nozzle unit 1, the front end face and the terminal end face of the second nozzle unit 2, and the front end face of the third nozzle unit 3 are all circular.

[0041] In this embodiment, the above implementation makes processing easy, the overall structure is more complete, and the rotation between adjacent nozzle units is easier to achieve.

[0042] Furthermore, the angle between the front end surface of the second nozzle unit 2 and the center axis of the second nozzle section unit is greater than or equal to 22.5°.

[0043] In this embodiment, the above angle is limited to be greater than or equal to 22.5°, combined with the aforementioned symmetrical arrangement of the front end face and the terminal end face of the second nozzle unit 2 relative to the cross section of the second nozzle unit 2, combined with the aforementioned mutual adaptation of the inclined surface structure between the two adjacent nozzle units, it can be obtained that: the angle between the rear end face of the first nozzle unit 1 and the central axis of the first nozzle unit 1 is greater than or equal to 22.5°, the angle between the rear end face of the second nozzle unit 2 and the central axis of the second nozzle unit 2 is greater than or equal to 22.5°, and the angle between the front end face of the third nozzle unit 3 and the central axis of the third nozzle is greater than or equal to 22.5°. As implemented above, the maximum deflection state of the three-bearing vector nozzle structure can achieve an inkjet angle adjustment of greater than or equal to 90°.

[0044] Furthermore, the angle between the front end surface of the second nozzle unit 2 and the center axis of the second nozzle unit 2 is equal to 22.5°.

[0045] In this embodiment, the aforementioned angle is preferably 22.5°, which can achieve a maximum adjustment of the inkjet angle to 90°, and can meet the current requirements for inkjet marking.

[0046] Figure 1 and Figure 2 The two states of the three-bearing vector nozzle structure in this embodiment are shown. Figure 2 The maximum bending state is 90°.

[0047] In this embodiment, the nozzle connection mechanism includes a rotating gear 5 and a driving motor; the rotating gear 5 is fixedly arranged at the front end of the second nozzle unit 2, and the driving motor is correspondingly fixedly arranged on the first nozzle unit 1; the rotating gear 5 is fixedly arranged at the front end of the third nozzle unit 3, and the driving motor is correspondingly fixedly arranged on the second nozzle unit 2. It is preferably implemented as above, and the control connection and driving structure are simple and easy to implement.

[0048] Figure 3 A simplified three-dimensional diagram of the adjustable inkjet head in this embodiment is shown, which obviously does not include the simplified schematic diagram of the telescopic inkjet tube 4.

[0049] Furthermore, considering that the driving motor is used for adjusting the rotation angle between adjacent nozzle structures, it is preferred to use a servo motor 6 .

[0050] In some embodiments, the telescopic inkjet tube 4 is located at one side of the end of the vector nozzle structure and is fixedly connected to the vector nozzle structure to provide a relatively stable inkjet effect before and after rotation.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
