[0029] In the description of the utility model, unless otherwise stated, the meaning of "a plurality of" is two or more than two.In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0030] In one embodiment of the utility model, as shown in Figures 1-5 The utility model provides a kind of nozzle for line drawing machine, including: nozzle body 1 and cleaning needle 2.Nozzle body 1;Cleaning needle 2, from the side of nozzle body 1 along the nozzle bottom of nozzle body 1 reciprocating motion, and from the nozzle bottom of nozzle body 1 along the ink channel of nozzle body 1 reciprocating motion.

[0031] The utility model provides a kind of nozzle for line drawing machine, by cleaning needle 2 from the side of nozzle body 1 along the nozzle bottom of nozzle body 1 reciprocating motion, when nozzle body 1 carries out ink jet work, cleaning needle 2 can avoid the ink flow being in the process of jetting, to avoid interference to normal ink jet process, ensure that line drawing operation can continue, stably and accurately carry out;And further from the nozzle bottom of nozzle body 1 along the ink channel of nozzle body 1 reciprocating motion, effectively clean the effect of dredging to ink channel, guarantee the fluency and accuracy of ink jet of nozzle.

[0032] The nozzle for line drawing machine further includes rotating assembly 3, is set to the side of nozzle body 1, to drive cleaning needle 2 from the side of nozzle body 1 along the nozzle bottom of nozzle body 1 reciprocating motion, the setting of rotating assembly 3 improves the accuracy and controllability of cleaning needle 2 movement.

[0033] When the cleaning needle 2 is in standby state, and the ink ejection process of the inkjet head body 1 is in normal operation, the rotating assembly 3 can rotate the cleaning needle 2 to keep a safe distance from the ink flow being ejected, so as to avoid interfering with the ink ejection process, and ensure that the line drawing operation can continue, stabilize and accurately proceed without obstruction.

[0034] With the continuous ink ejection of the inkjet head, some impurities will inevitably adhere to the bottom of the nozzle, affecting the ink ejection effect. The rotating assembly 3 can be driven to rotate the cleaning needle 2 to the bottom of the nozzle to prepare for cleaning work, ensuring the smoothness of the nozzle, so that the subsequent ink ejection work of the inkjet head can be restored to normal.

[0035] Specifically, the rotating assembly 3 includes a driving source 31 and a connecting plate 32. The driving source 31 is positioned on the upper side of the inkjet head body 1. The driving source 31 can be an electric motor. The upper end of the connecting plate 32 is installed on the driving end of the driving source 31. The cleaning needle 2 is arranged at the lower end of the connecting plate 32. The lower end of the connecting plate 32 is rotated by the driving source 31, so that the cleaning needle 2 is rotated to the bottom of the nozzle of the inkjet head body 1.

[0036] In the embodiment, the driving source 31 drives the cleaning needle 2 in the following manner: driving the driving source 31, the driving source 31 drives the connecting plate 32 to rotate, and the connecting plate 32 drives the cleaning needle 2 to rotate from the side of the inkjet head body 1 to the bottom of the nozzle of the inkjet head body 1.

[0037] Preferably, the rotating assembly 3 further comprises a connecting ring 4. One end of the connecting ring 4 is detachably positioned at the lower end of the inkjet head body 1. The connecting ring 4 can be installed in a threaded screwing manner. The other end of the connecting ring 4 is connected to the rotating assembly 3.

[0038] The connecting ring 4 is installed in a threaded screwing manner, which is simple to operate and does not require complex tools or professional skills, saving installation time and labor costs. When the inkjet head needs to be maintained, repaired or replaced, the connecting ring 4 can be easily detached from the inkjet head body 1 by the maintenance personnel, without damaging the structure of the inkjet head body 1 and the connecting ring 4, and facilitating the replacement of the connecting ring 4 itself.

[0039] The nozzle of the line drawing machine also includes a telescopic assembly 5 arranged at the bottom end of the connecting plate 32 to drive the cleaning needle 2 to reciprocate along the ink ejection channel of the nozzle body 1 from below the nozzle of the nozzle body 1. In actual use scenarios, in the case of continuous line drawing for a long time, impurities will accumulate at the bottom of the nozzle, which will have an increasingly obvious impact on the ink ejection effect. When such a situation occurs, the operator can start the telescopic assembly 5 to accurately drive the cleaning needle 2 to perform telescopic movement, so that it enters the ink ejection channel along the bottom of the nozzle of the nozzle body 1 and reciprocates in the channel. The impurities at the bottom of the nozzle or inside the ink ejection channel can be cleaned in time, the ink ejection channel is restored to unobstructed, and the nozzle can again eject ink normally, ensuring that the nozzle can always function stably and maintain a good working state in complex pattern drawing or large-scale line drawing scenarios.

[0040] Specifically, the telescopic assembly 5 includes a power source 51, a power tooth 52, and a matching tooth 53. The power source 51 can be an electric motor, the power tooth 52 can be a gear, and the matching tooth 53 can be a straight tooth. The cleaning needle 2 reciprocates along the nozzle of the nozzle body 1 through the connecting plate 32. The power source 51 is positioned at the bottom end of the connecting plate 32, the power tooth 52 is positioned at the power end of the power source 51, and the matching tooth 53 is arranged on the surface of the cleaning needle 2. The matching tooth 53 is engaged with the power tooth 52. Positioning the power source 51 at the bottom end of the connecting plate 32 avoids conflicts in space with components such as the nozzle and other drive assemblies on the nozzle body 1, making the layout inside the entire nozzle more compact and orderly.

[0041] In this embodiment, the connection mode of the power source 51 driving the cleaning needle 2 is as follows: driving the power source 51 drives the power tooth 52 to rotate, which engages the matching tooth 53 on the cleaning needle 2, thereby driving the cleaning needle 2 to reciprocate along the ink ejection channel of the nozzle body 1 from below the nozzle of the nozzle body 1.

[0042] Specifically, the auxiliary assembly 6 includes a sliding groove 61 and a sliding block 62. The sliding groove 61 is arranged on the side surface of the connecting plate 32, and the sliding block 62 is connected between the sliding groove 61 and the cleaning needle 2.

[0043] In actual work, when the telescopic assembly 5 drives the cleaning needle 2 to reciprocate, especially to move along the ink ejection channel of the nozzle body 1 from below the nozzle of the nozzle body 1, the cleaning needle 2 will connect the sliding block 62 to slide along the sliding groove 61 accordingly. The sliding groove 61 provides precise and stable guidance for the sliding block 62, thereby limiting the cleaning needle 2 to move only in the intended direction, avoiding unstable situations such as deviation or shaking of the cleaning needle 2, further ensuring the accuracy of the reciprocating movement of the cleaning needle 2 in the ink ejection channel, ensuring that the cleaning work can be smoothly and efficiently completed, and helping to maintain good ink ejection performance of the nozzle.

[0044] Preferably, the upper end of the cleaning needle 2 is reduced in diameter to form a pointed portion, so as to pierce the caked waste material blocked in the nozzle of the printhead body 1. After the printhead is used for a long time, the ink is dried, impurities are mixed, and so on, so that the caked waste material is easily formed in the nozzle of the printhead body 1. These caked waste materials are often hard in texture, and are firmly blocked in the nozzle, which seriously hinders the normal ejection of the ink, and further affects the smooth development of the drawing operation. The pointed portion formed on the upper end of the cleaning needle 2, by virtue of its small contact area and sharp shape, can effectively pierce the caked waste material when the nozzle needs to be cleaned, and decompose it into smaller fragments. Subsequently, by means of the reciprocating movement of the cleaning needle 2 and other cleaning means, the fragments can be cleaned out of the nozzle, so that the nozzle is restored to be unobstructed, and the ink can be smoothly ejected, so as to ensure the ink ejection performance of the printhead and the quality and precision of the drawing.

[0045] Preferably, the cleaning device further comprises a cotton 7 arranged on the top surface of the connecting plate 32. The cotton 7 can be bonded with the connecting plate 32, and the inner diameter of the cotton 7 can be greater than the diameter of the cleaning needle 2, so that the cleaning needle 2 will not damage the cotton 7 during the reciprocating movement. The cotton 7 is used to absorb the falling waste material, so as to avoid the splashing of the waste material. The selected cotton 7 can have a loose and porous structure, which can well absorb various small waste particles, such as the debris of dried ink, dust and impurities, and the fragments of the caked waste material after being cleaned by the cleaning needle 2. The cotton 7 is arranged on the top surface of the connecting plate 32. On the one hand, the connecting plate 32 is near the relevant cleaning components of the printhead, and is one of the main areas where the waste material falls, so that the cotton 7 can maximize its adsorption effect here. On the other hand, during the daily maintenance or inspection of the printhead, the staff can conveniently observe the adsorption condition of the cotton 7. When the cotton 7 adsorbs too much waste material, it can be easily taken down for replacement or cleaning, which is simple and convenient. Moreover, the soft texture of the cotton 7 will not cause scratching, collision and other damages to other components of the printhead, so as to ensure the safety and stability of the entire printhead system during the working process, and effectively avoid the many adverse effects caused by the splashing of the waste material.

[0046] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application is disclosed as the above preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above disclosed technical content without departing from the technical solution of the present application, so as to obtain equivalent embodiments with equivalent changes.
