DETAILED DESCRIPTION

[0026] The application will be further described in detail below with reference to the accompanying drawings. Embodiment 1

[0027] The application discloses a kind of anti-clogging inkjet structure.

[0028] With reference to Figures 1 to 3 Anti-clogging inkjet structure 1 includes substrate 11, support plate 12, inkjet system 13 mounted on substrate 11, and elastic pad 14 mounted on support plate 12; Elastic pad 14 is made of gasket made of sealing material with certain elasticity, such as: rubber pad or silica gel pad, etc.

[0029] Among them, substrate 11 is connected with lifting unit 15 for driving inkjet system 13 to reciprocate relative to inkjet working surface, and substrate 11 and support plate 12 can move relative to each other; When inkjet system 13 is located above support plate 12, the nozzle of inkjet system 13 is in contact with elastic pad 14.

[0030] Further, since the installation height of ink cartridge is usually higher than the nozzle, a protruding portion 121 is arranged between elastic pad 14 and support plate 12, the protruding portion 121 corresponds to the nozzle of inkjet system 13, and when the nozzle of inkjet system 13 is in contact with elastic pad 14, the height of protruding portion 121 compensates for the height difference between the nozzle and ink cartridge, so that elastic pad 14 is more closely sealed at the nozzle of inkjet system 13, and the clogging frequency of ink supply system is reduced.

[0031] Inkjet system 13 can be provided with multiple groups of inkjet units, and the protruding portion 121 is arranged one-to-one corresponding to the number of inkjet units, and the elastic pad 14 can cover the nozzle area of multiple groups of inkjet units.

[0032] Lifting unit 15 can be a driving cylinder assembly or a lead screw transmission assembly or a gear rack assembly or a pulley assembly; The preferred structure in the embodiment is to include base 151, reset elastic member 152, fixed seat 153 mounted on substrate 11, and cam 154 rotatably mounted on base 151; Reset elastic member 152 can be a tension spring or a torsion spring or a rubber pad with certain elasticity, and reset elastic member 152 is installed between fixed seat 153 and base 151 and causes the peripheral surface of cam 154 to be in contact with fixed seat 153.

[0033] By rotating cam 154 to change the relative position of the position where it is in contact with fixed seat 153, reset elastic member 152 is deformed, and by the interaction of the rotation of cam 154 and reset elastic member 152, inkjet system 13 can reciprocate relative to the inkjet working surface, so as to place support plate 12 under inkjet system 13 or take it out from under inkjet system 13.

[0034] The principle of implementation is: when the inkjet printing / line drawing device stops working, the cam 154 of the lifting unit 15 is rotated to change the position of the contact between the cam 154 and the fixed seat 153, so that the substrate 11 drives the inkjet system 13 to move upward relative to the inkjet working surface. At this time, the support plate 12 is placed below the nozzle of the inkjet system 13, and then the cam 154 is rotated to make the substrate 11 move downward under the action of the reset elastic member 152, so that the nozzle of the inkjet system 13 is in contact with the elastic pad 14. The elastic pad 14 is tightly sealed at the nozzle of the inkjet system 13, which prevents the ink in the inkjet system 13 and the nozzle from contacting the air, reduces the frequency of ink supply system blockage, and improves the inkjet efficiency of the ink supply system. When the inkjet printing / line drawing device is restarted, the substrate 11 is moved upward by rotating the cam 154, and then the support plate 12 is removed from below the inkjet system 13.

When the inkjet system 13 is above the support plate 12, the nozzle of the inkjet system 13 is in contact with the elastic pad 14.

[0038] The implementation principle is: when the inkjet device stops working, the substrate 11 drives the inkjet system 13 to move upwards relative to the workbench 3 through the lifting unit 15, at this time the supporting plate 12 is slid under the inkjet head of the inkjet system 13, and then the substrate 11 drives the inkjet system 13 to move downwards through the lifting unit 15, so that the inkjet head of the inkjet system 13 is in contact with the elastic pad 14, the elastic pad 14 is tightly sealed at the inkjet head of the inkjet system 13, and the ink in the inkjet system 13 and the inkjet head is isolated from air; when the inkjet device is restarted, the substrate 11 drives the inkjet system 13 to move upwards relative to the workbench 3 through the lifting unit 15, and then the supporting plate 12 is slid out from under the inkjet system 13, the material to be inked or drawn is placed on the conveying belt of the conveying belt assembly, and the stability of the material conveying is stabilized through the pressing unit 5, the visual unit 4 picks up the position of the material to be inked or drawn, and sends a signal to the inkjet system 13, so that the inkjet system 13 performs the inkjet or drawing process.
