Embodiment Construction
[0025] like Figures 1 to 3 as well as Image 6 As shown, a non-contact ink dotting device includes a valve seat 1, a valve core 2 and a cylinder 13, the valve seat 1 is a cuboid structure, the valve core 2 is a cylindrical rod body, and the valve seat 1 is fixed on the frame (the part in the figure The frame is shown), the cylinder body of the cylinder 13 is fixed on the frame, the piston end is connected with the valve core 2 through the connector 14, the valve seat 1 is provided with a hole 3, the hole 3 is a through hole and is a round hole, the valve The core 2 is sleeved in the hole 3 and is slidingly fitted with the valve seat 1. The hole 3 penetrates from the left side of the valve seat 1 to the right side of the valve seat 1. The valve core 2 is driven by the cylinder 13 to reciprocate and slide along the axial direction of the hole 3. Valve seat 1 is provided with ink inlet hole 4, air inlet hole 5 and ink outlet hole 6, and ink inlet hole 4, air inlet hole 5, ink o...

The invention provides a non-contact ink dotting device which is mainly used for paper folding dotting in the process of filter element manufacturing. The non-contact ink dotting device comprises a valve seat and a valve core. The valve seat is provided with a hole. The valve core is sheathed in the hole and is in sliding fit with the valve seat. The valve core is connected with a driving mechanism. The valve seat is provided with an ink inlet hole, an air inlet hole and an ink outlet hole. One ends of the ink inlet hole, the air inlet hole and the ink outlet hole penetrate through the side wall of the hole to be communicated with the hole. The valve core is provided with an ink storage tank. When the valve core slides in a reciprocating mode along the axial direction of the hole, the ink storage tank can move to the position of the ink inlet hole and be connected with the ink inlet hole to form a communication channel, and the ink storage tank can move to a position between the air inlet hole and the ink outlet hole and be connected with the air inlet hole and the ink outlet hole so that the air inlet hole, the ink storage tank and the ink outlet hole can form a communication channel. The device is designed into a non-contact ink jet mode, equality of ink-jet quantity at each time is ensured, the defects of traditional ink dotting devices can be effectively overcome, the product quality is ensured, the work efficiency is improved, the device can be externally connected with a large-capacity ink storage device, and the manufacturing cost is reduced.
Description
technical field [0001] The invention relates to an ink dotting device, in particular to a non-contact automatic inkjet dotting device. Background technique [0002] The traditional origami dotting device is to install a marking pen, and control the up and down movement of the marking pen through a pneumatic switch, so as to realize marking on the moving filter paper. Its main disadvantages are: the nib is easy to wear and needs to be replaced frequently; the amount of ink is difficult to control, often appearing unevenly dotted, and the phenomenon of more and less ink; the ink storage in the refill is small, and ink needs to be added frequently, requiring a special person take care of. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a non-contact ink dotting device. This device is designed as a non-contact inkjet, and the inkjet volume is equal each time, which can effectively solve the shortcomings of tradition...
