Problems solved by technology

[0008] In the above-mentioned inkjet device, as a sealing structure in which a sealing material is filled in the gap between the above-mentioned shield plate and the inkjet head, the stress generated due to the shrinkage of the filled sealing material when solidified may affect the shape accuracy of the inkjet head itself. , in addition, if there are large and small parts in the above-mentioned gap, unevenness may appear on the surface of the filled sealing material, and the filling and curing time of the sealing material are locally different. , as a whole, the filling and curing time of the sealing material will be extended
[0009] Furthermore, for a sealing structure using a sealable gasket, both the shape accuracy of the gap and the shape accuracy of the gasket must be high-precision, so the product price is high

[0019] Figure 1 ~ Figure 3 The first embodiment of the present invention is shown.

[0020] exist Figure 1 ~ Figure 3 Among them, the inkjet device 1 has an inkjet head 10, a head mounting member 30 for positionally adjustable mounting of the inkjet head, and a pair of opposing side covers 50A, 50B constituting exterior members mounted to the head mounting member 30 with screws or the like.

[0021] In a state where the pair of side covers 50A, 50B are attached to the head mounting member 30 , an upper opening 50C is formed at the upper portion of the pair of side covers 50A, 50B, and a lower opening 50D is formed at the lower portion. The head mounting member 30 is mounted to an inkjet recording device (not shown) so as to be adjustable in the up-down, front-back, left-right directions, etc., and is adjusted so that the distance from the printing paper is L1.

[0022] The inkjet device 1 further includes a top cover 60 that constitutes an exterior member that covers the u...

[0040] Figure 4 The second embodiment of the present invention is shown.

[0041] In the present embodiment, vertical grooves 52 are formed at appropriate intervals in the cover lower portions 51 of the side covers 50A and 50B. The cover lower part 51 and its upper part have a step, and the ink dripped along the outer surfaces of the side cover 50A and side cover 50B passes through the step or directly collects in the above-mentioned vertical groove part 52, and is sealed by the sealing surface of the sealing body 91 and the cover lower part 51. Into the small gap 93.

[0042] Therefore, leaked ink required to complete the surface tension sealing around the small gap 93 can be collected without waste, and the surface tension sealing can be completed in advance after the inkjet recording apparatus is started to be used.

[0043] According to each of the above-described embodiments, from the factory shipment of the inkjet device 1 that does not require sealing to the user's r...

Abstract

According to one embodiment, an inkjet device includes: an inkjet head; an armor section configured to surround the periphery of the inkjet head; a first gap formed over the entire periphery in the peripheral direction in a plurality of the armor sections; and a seal body for forming a surface tension seal by fluid in a second gap arranged in the first gap to form a gap narrower than the first gap.

Description

technical field [0001] Embodiments of the present invention relate to a sealing structure for protecting exterior components such as inkjet heads and wiring components. Background technique [0002] An inkjet device used in an inkjet recording device includes an inkjet head, a head mounting member of the inkjet head mounted in the inkjet recording device, a circuit connected to electrodes of the inkjet head through a flexible wiring board or the like A substrate, an exterior member covering the above-mentioned inkjet head and the above-mentioned circuit board, and the like. [0003] In the inkjet device described above, the inkjet head is positioned and fixed with respect to the head mounting member so that the nozzle plate and the printing surface are at a predetermined distance. [0004] Furthermore, as the exterior member, there are, for example, a head cover (shield plate) disposed around the inkjet head, a cover member covering the circuit board and the head mounting m...
