Description

Technical Field

[0001] The invention relates to a conversion device for a nozzle of an inkjet printer, belonging to the technical field of inkjet printers. Background Art

[0002] The inkjet printer is a device that uses software to achieve product coding and marking, and the printhead is its core component. Currently, the printhead is generally installed on the inkjet printer using fasteners such as bolts and connected to the ink supply path. However, during the ink supply and coding process, the printhead is very prone to clogging, resulting in interruption of the coding operation. To maintain operation, the printhead needs to be maintained, but the existing maintenance process is cumbersome: first, the machine must be shut down, then the printhead must be returned to its original position to avoid obstacles such as the product to be coded, and then the printhead must be removed and replaced in sequence. The printer must then be repositioned to return the printhead to the coding position before it can continue to operate. This series of operations significantly prolongs the coding time and reduces work efficiency. In addition, after the printhead is clogged and returned to its original position, it is very easy for the coding to deviate, thus affecting the coding quality and effect. Summary of the Invention

[0017] Example 2: Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 and Figure 9 As shown, the function box 93 located at the rear side of the fixed plate 54 is set on the left wall inside the rectangular groove 52, and the movable plate 9 extending into the function box 93 is slidably connected to the right end of the function box 93. The function box 93 is used in conjunction with the movable plate 9 to block the connection hole 51. The right end surface of the function box 93 is recessed to the left to form a first groove 931, and the movable cylinder 22 located on the uppermost side passes through the first groove 931. The movable cylinder 22 located on the uppermost side passes through the function box 93 through the first groove 931. The left end surface of the movable plate 9 is recessed to the right to form a second groove 94 whose center line coincides with the center line of the first groove 931. The movable cylinder 22 located on the uppermost side passes through the second groove 94. The movable cylinder 22 located on the uppermost side passes through the movable plate 9 through the second groove 94. The electromagnet 92 is embedded in the right end of the movable plate 9, and the magnetic plate 91 located on the right side of the electromagnet 92 and arranged to be mutually attracted with the electromagnet 92 is installed on the right wall inside the rectangular groove 52. The electromagnet 92 and the magnetic plate 91 are used in conjunction with each other to make the movable plate 9 move to the right. Two guide holes located on the upper and lower sides of the second groove 94 are formed on the left end surface of the movable plate 9 and recessed to the right. The guide posts are guided through the guide holes. Then, two guide posts extending into the guide holes and having their other ends respectively connected to the left ends of the two guide holes are symmetrically arranged on the left wall inside the function box 93. The two guide posts are used in conjunction with each other to guide the movement of the movable plate 9. The two first elastic members 932 located on the outside of the two guide pillars are symmetrically installed between the left end of the movable plate 9 and the left wall inside the function box 93. The two first elastic members 932 are used in conjunction with each other to return the movable plate 9 to its original position. The first elastic member 932 can be a spring. The outer end of the movable cylinder 22 located on the uppermost side and the auxiliary plate 521 at the rear end of the function box 93 are installed on the inside of the rectangular groove 52. The auxiliary plate 521 is used to provide a processing carrier for the sealing groove. The inner wall surface of the auxiliary plate 521 is recessed outward to form a sealing groove. The sealing groove provides an installation space for the sealing ring 522. The sealing ring 522 at the outer end of the movable cylinder 22 on the uppermost side is installed in the sealing groove. The movable cylinder 22 on the uppermost side is sealed and installed by the sealing ring 522. The two fixing bars 951 located on the upper and lower sides of the electromagnet 92 are symmetrically mounted on the right rear end of the movable plate 9, and the fixing bars 951 provide a mounting carrier for the round rod 95, and the two round rods 95 located on the upper and lower sides of the second groove 94 and connected to the right end of the function box 93 at their other ends are respectively arranged on the left ends of the two fixing bars 951, and the two round rods 95 slidably connected to the movable plate 97 both penetrate the movable plate 97, and the two round rods 95 are used in conjunction to guide the movement of the movable plate 97, and then the movable plate 97 is slidably connected to the rear end of the movable plate 9, and a mounting carrier is provided for the blocking plate 96 through the movable plate 97; A blocking plate 96 located between the two round rods 95 and having a semicircular cross-section is installed on the left end of the movable plate 97, and the blocking plate 96 is used in conjunction with the first groove 931 and is located on the right side of the second groove 94. The first groove 931 is blocked by the blocking plate 96, and a magnetic strip 971 located on the left side of the electromagnet 92 and adsorbed with the electromagnet 92 is set on the middle part of the right end of the movable plate 97. The electromagnet 92 and the magnetic strip 971 are used in conjunction to make the movable plate 97 move to the left. Then, the second elastic members 98 located at the other ends of the outer sides of the round rods 95 and connected to the right end of the movable plate 97 are respectively installed on the left ends of the two fixed bars 951. The two second elastic members 98 are used in conjunction to return the movable plate 97 to its original position. The second elastic member 98 can be a spring.

[0018] When converting the nozzle 2, the servo motor 43, the auxiliary gear 42, the synchronous belt and the ring gear 7 are first used to rotate the straight cylinder 6, the four mounting plates 3 and the four nozzles 2, so that the movable cylinder 22 on one nozzle 2 is rotated to the front of the socket 541, and then the corresponding two second electric push rods 24 and the two first plates 23 are used to insert the corresponding movable cylinder 22 into the socket 541, and at the same time, the circuit of the electromagnet 92 is turned on, so that magnetic fields are generated at both ends of the electromagnet 92. Because the magnetic plate 91 and the electromagnet 92 are arranged to be attracted to each other, 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 extreme position, and stretches the two first elastic members 932, so that the first elastic member 932 generates an elastic force. At this time, the first groove 931 and the second groove 94 form a circular hole, and the circular hole coincides with the socket 541; Because the magnetic strip 971 and the electromagnet 92 are arranged to attract each other, an attraction force is generated between the magnetic strip 971 and the electromagnet 92. Under the action of the attraction force, the movable plate 97 moves rightward along the round rod 95, thereby compressing the two second elastic members 98, so that the second elastic members 98 generate an elastic force. At the same time, the rightward movement of the movable plate 97 causes the blocking plate 96 to move rightward to the extreme position. At this time, the blocking plate 96 is located on the right side of the second groove 94. Then, the corresponding movable cylinder 22 is fully inserted into the insertion hole 541, so that the corresponding movable cylinder 22 is connected to the connecting hole 51. Then the circuit of the electromagnet 92 is disconnected, so that the adsorption force generated between the electromagnet 92 and the magnetic plate 91 and the magnetic strip 971 disappears. At this time, under the elastic force of the two first elastic members 932, a leftward pulling force can be applied to the movable plate 9, and then under the action of the first groove 931 of the function box 93 and the second groove 94 of the movable plate 9, the corresponding movable cylinder 22 is clamped. Then, the ink pump 12 and other components are used to perform coding operations to clamp the working movable cylinder 22, effectively reducing the probability of the movable cylinder 22 retracting under the impact of flowing ink, effectively reducing the probability of ink leakage during coding, and effectively reducing the probability of false coding during coding.

[0019] When a blockage or other fault occurs in the uppermost nozzle 2, the ink pump 12 is first stopped, and then the two uppermost second electric push rods 24 are started, thereby causing the corresponding two first plates 23 to move forward, thereby causing the corresponding movable cylinder 22 to move forward. When the rear end of the movable cylinder 22 enters the second groove 94, the elastic force of the two second elastic members 98 causes the blocking plate 96 and the movable plate 97 to move leftward, thereby causing the blocking plate 96 to enter the first groove 931, thereby blocking the rear part of the circular hole formed by the first groove 931 and the second groove 94, thereby performing a primary blockage on the insertion hole 541 that coincides with the circular hole. 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, thereby making the second groove 94 on the movable plate 9 completely enter the function box 93, thereby blocking the insertion hole 541 again, and then the movable cylinder 22 continues to move forward, thereby separating the movable cylinder 22 from the insertion hole 541, realizing segmented two-way blocking of the insertion hole 541, effectively reducing the probability of leakage during the disassembly and assembly of the movable cylinder 22, effectively reducing the probability of solidified residual ink at the opening position of the insertion hole 541, and effectively reducing the probability of obstruction during the docking operation between the movable cylinder 22 and the insertion hole 541, thereby effectively ensuring the conversion effect of the nozzle 2 and the inkjet quality; 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, so that the movable cylinder 22 on one nozzle 2 is rotated to the front of the socket 541, and then the corresponding two second electric push rods 24 and the two first plates 23 and other components are used to connect the corresponding movable cylinder 22 with the connecting hole 51 again, and then the ink pump 12 and other components are used to continue the coding operation.

[0020] Example 3: Figure 2 、 Figure 3 、 Figure 7 and Figure 10 As shown, the rear wall surface of the inner part of the rectangular groove 52 is recessed backward to form a circular groove 53 located in the cylinder 5, and the insertion hole 541 passes through the circular groove 53, providing installation space for components such as the fixing ring 532, and the elastic ring 533 located in the circular groove 53 is sleeved on the outer end of the movable cylinder 22 located at the uppermost side, and the outer surface of the movable cylinder 22 located at the uppermost side is flexibly cleaned through the elastic ring 533, and the fixing ring 532 located outside the elastic ring 533 is installed in the circular groove 53, and the fixing ring 532 provides a mounting carrier for the guide rod 531, and then a plurality of guide rods 531 located in the circular groove 53 and extending outside the fixing ring 532 are equidistantly installed on the outer end of the elastic ring 533, and the fixing ring 532 is slidably connected to the guide rod 531, and the plurality of guide rods 531 are used in conjunction to restrict the installation of the elastic ring 533, and a spherical surface is provided at the rear end of the movable cylinder 22, and the elastic ring 533 can be expanded through the spherical surface.

[0021] When switching the nozzles 2, the servo motor 43, the auxiliary gear 42, the synchronous belt and the ring gear 7 are first used to rotate the straight cylinder 6, the four mounting plates 3 and the four nozzles 2, thereby rotating the movable cylinder 22 on one nozzle 2 to the front of the insertion hole 541. Then, the corresponding two second electric push rods 24 and the two first plates 23 are used to insert the corresponding movable cylinder 22 into the insertion hole 541. At the same time, the electromagnet 92, the magnetic plate 91 and the magnetic strip 971 are used to form a circular hole between the first groove 931 and the second groove 94, and the circular hole coincides with the insertion hole 541, and the blocking plate 96 is moved to the right side of the second groove 94.
