[0027] The threaded block 12 is fixedly connected to a first return spring 20, and the first return spring 20 is located in a cavity opened in the limit block 4;

[0028] The limit block 4 is fixedly connected with a first wedge block 14, a second wedge block 13 for driving the first wedge block 14 to move upward is arranged below the first wedge block 14, and a driving block 15 for driving the first wedge block 14 to move downward is arranged on the side of the first wedge block 14, and the driving block 15 is fixedly connected with the slide rail 3;

[0030] As a further solution of the utility model, the transmission assembly includes a first transmission wheel 7, which is movably installed on the threaded rod 5, and the first transmission wheel 7 is connected to the second transmission wheel 10 through a transmission belt 9. The second transmission wheel 10 is fixedly connected to a transmission gear 11 at a rotating part of the second transmission wheel 10, and the transmission gear 11 is rotatably connected to the bracket 2 at its rotating shaft, and the gear of the transmission gear 11 is meshed with a chain belt 19, and the two ends of the chain belt 19 are transmission connected to the transmission roller 18.

[0032] As a further solution of the present invention, a surface of the lower surface of the threaded block 12 that contacts the threaded rod 5 is provided with threads.

[0033] Working principle: Start the first motor 6, the first motor 6 drives the threaded rod 5 to rotate (because a spring is provided in the first transmission wheel 7, the threaded rod 5 drives the spring to rotate, and the first transmission wheel 7 does not move) the threaded rod 5 rotates to drive the limit block 4 to move rightward, the limit block 4 drives the sliding block 23 to move rightward on the slide rail 3, drives the coding block 16 to move rightward, and codes the square bottom valve bags on the conveyor belt 17;

[0034] When the limit block 4 drives the sliding block 23 to move to the process of contacting the fixed block 21, the second return spring 8 is compressed. At the same time, the driving block 15 drives the first wedge block 14 to move downward, and the first wedge block 14 drives the limit block 4 to move downward.

At this time, the first motor 6 stops working; since the upper end of the slide groove 22 is not threaded, the threaded rod 5 is in a sliding state, and under the action of the second return spring 8, it quickly slides back to the initial state, which speeds up the speed of returning the sliding block 23 and the inkjet block 16 to the initial position. There is no need to rotate the threaded rod 5 to return the sliding block 23 and the inkjet block 16 to the initial position, which avoids this process being relatively slow and reducing efficiency;

[0035] At the same time, since the threaded rod 5 stops rotating, the spring on the first transmission wheel 7 drives the first transmission wheel 7 to rotate, and the first transmission wheel 7 drives the transmission gear 11 to rotate through the transmission belt 9, and the transmission gear 11 drives the chain belt 19 to transmit, and the chain belt 19 drives the transmission roller 18 to rotate, and the transmission roller 18 drives the conveyor belt 17 to rotate, and the conveyor belt 17 transports the printed square bottom valve bag away, and the square bottom valve bag to be printed is transported to the bottom of the coding block 16 for coding, and this reciprocating process is realized, so that the transportation and transmission of the square bottom valve bag can be realized at the same time when the coding block 16 returns.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
