Description

TECHNICAL FIELD

[0002] As a device for realizing product code marking through software control, the nozzle is the core accessory of the ink-jet printer. Currently, the nozzle is generally installed in the ink-jet printer by fixing members such as bolts and is in communication with the ink conveying path. However, during the ink conveying and code spraying processes, the nozzle is prone to blockage, resulting in interruption of the code spraying operation. In order to maintain the work, the nozzle needs to be maintained, but the existing maintenance process is complicated: first, the machine needs to be stopped, then the return operation needs to be performed to avoid obstacles such as products to be sprayed, then the nozzle needs to be disassembled and replaced in turn, and then the ink-jet printer needs to be positioned, so that the nozzle can return to the code spraying position and the operation can continue. This series of operations significantly prolongs the code spraying time and reduces the work efficiency.

[0066] When the conversion nozzle 2 is converted, the straight cylinder 6, the four mounting plates 3 and the four nozzles 2 are rotated by the servo motor 43, the auxiliary gear 42, the synchronous belt and the ring gear 7, and then the movable cylinder 22 on the nozzle 2 is rotated to the front of the insertion hole 541, and then the corresponding movable cylinder 22 is inserted into the insertion hole 541 by the corresponding two second electric push rods 24 and the two first plates 23, and the circuit of the electromagnet 92 is turned on, so that the electromagnet 92 generates a magnetic field at both ends, and because the magnetic plate 91 and the electromagnet 92 are arranged to be mutually adsorbed, an adsorption force is generated between the magnetic plate 91 and the electromagnet 92, and under the action of the adsorption force, the movable plate 9 moves to the right along the function box 93 to the limit position and stretches the two first elastic members 932, so that the first elastic member 932 generates an elastic force, and at this time, the first recess 931 and the second recess 94 form a circular hole, and the circular hole coincides with the insertion hole 541.

[0067] Because the magnetic strip 971 and the electromagnet 92 are arranged to be mutually adsorbed, an adsorption force is generated between the magnetic strip 971 and the electromagnet 92, and under the action of the adsorption force, the moving plate 97 moves to the right along the circular rod 95, thereby compressing the two second elastic members 98, so that the second elastic member 98 generates an elastic force, and at the same time, the right movement of the moving plate 97 will make the blocking plate 96 move to the right to the limit position, and at this time, the blocking plate 96 is located on the right side of the second recess 94, and then the corresponding movable cylinder 22 is completely inserted into the insertion hole 541, so that the corresponding movable cylinder 22 is in communication with the connecting hole 51.

[0069] When a blockage fault occurs in the uppermost nozzle 2, first stop the ink pump 12, and then start the two second electric push rods 24 at the uppermost side, thereby making the corresponding two first plates 23 move forward, so that the corresponding movable cylinder 22 moves forward, and when the rear end of the movable cylinder 22 enters the second recess 94, the blocking plate 96 and the moving plate 97 move left under the elastic force of the two second elastic members 98, so that the blocking plate 96 enters the first recess 931, thereby blocking the rear part of the circular hole formed by the first recess 931 and the second recess 94, and thereby initially blocking the insertion hole 541 coinciding with the circular hole.

[0070] Then the rear end of the movable cylinder 22 continues to move forward along the second groove 94, and then the movable cylinder 22 is separated from the second groove 94, at this time, under the elastic force of the two first elastic members 932, the movable plate 9 moves to the left, and then the second groove 94 on the movable plate 9 is completely inserted into the functional box 93, and then the jack 541 is sealed again, and then the movable cylinder 22 continues to move forward, and then the movable cylinder 22 is separated from the jack 541, realizing the segmented bidirectional sealing of the jack 541, effectively reducing the leakage probability in the disassembly of the movable cylinder 22, effectively reducing the probability of solidified residual ink in the opening position of the jack 541, effectively reducing the probability of blockage between the movable cylinder 22 and the jack 541, and effectively ensuring the conversion effect of the nozzle 2 and the code quality.

[0071] Then the servo motor 43, the auxiliary gear 42, the synchronous belt, and the ring gear 7 are used to rotate the straight cylinder 6, the four mounting plates 3, and the four nozzles 2, and then the corresponding two second electric push rods 24 and the two first plates 23 are used to make the corresponding movable cylinder 22 and the connecting hole 51 communicate again, and then the ink pump 12 is used to continue the code printing operation.
