The sock-setting tube 22 includes a tube body for setting the sock 9. The tube body is in the shape of a hollow round tube with two ends open. A straight groove 221 is arranged on the tube body along the length direction of the tube body. The straight groove 221 runs through the inner and outer side walls of the tube body, and the straight groove 221 is parallel to the axial direction of the tube body. The straight groove 221 facilitates the subsequent positioning hook 351 (described in detail below) to extend downward to the inner cavity of the tube body and enables the positioning hook 351 to hook the cuff of the sock 9 from the inner cavity of the tube body to the outside.

[0037] It is worth noting that the fifth moving mechanism 23 in this embodiment can adopt a slider to cooperate with a linear slide rail, and in this embodiment, the fifth moving mechanism 23 adopts a lead screw. The purpose of setting the fifth moving mechanism 23 in this embodiment is to adjust the horizontal movement of the clamping mechanism 24 so that the positioning hook 351 of the hook member 35 can be accurately aligned to the straight groove 221 of the sock tube 22, which is convenient for the subsequent sock removal operation. The rotating mechanism 25 in this embodiment can also adopt the rotating mechanism conventionally used in the market, such as using a motor to rotate. The purpose of setting the rotating mechanism 25 in this embodiment is to pre-set multiple first sock placement assemblies 2 to be removed.

[0050] 6. The sock tube 22 is clamped by a robot double-claw clamp (not shown in the figure) and placed on an unprinted material rack (not shown in the figure) in the order of arrangement.
[0051] 7. The sock tubes 22 on the unloading rack are clamped in sequence by the robot double-claw clamp according to the arrangement order. After taking the tubes, they are aligned with the center axis mechanism of the cylinder printer (not shown in the figure). After positioning, the machine automatically detects and starts printing.
[0052] 8. After printing is completed, the robot double-claw fixture removes the printed sock tube 22 and places it on the printed material rack in the order of arrangement, and repeats steps 6-8 at the same time;
[0053] 9. After the ink is air-dried without contamination, the printed sock tube 22 is manually transferred to the clamping mechanism 24 of the first sock placement assembly 22, and the sock tube 22 to be taken off is rotated to the side close to the first moving mechanism 32 by the rotating mechanism 25. At this time, the axis of the sock tube 22 is parallel to the length direction of the first moving mechanism 32; at the same time, the first moving mechanism 32 and the second moving mechanism 33 drive the pulling member 35 to move to the top of the sock tube 22 to be taken off, and the piston rod of the first cylinder 36 pushes the positioning hook 351 of the pulling member 35 downward and forward to move into the straight groove 221 of the sock tube 22, and continues to drive the piston rod to push the positioning hook 351 of the pulling member 35 upward and backward, so that the sock 9 is fixed at the crotch; at the same time, the third moving mechanism 42 and the fourth moving mechanism 43 drive the ejector rod 45 to move to the position aligned with the sock tube 22, and at this time, the axis of the ejector rod 45 coincides with the axis of the sock tube 22.
[0054] 10. Aligning to various directions, the first moving mechanism 32 drives the pulling member 35 and the third moving mechanism 42 drives the ejection rod 45 to move simultaneously in a direction away from the first sock placing assembly 2, the pulling hook 35 fixes the cuff of the sock 9, and the ejection rod 45 fixes the other end of the sock 9, so that the sock 9 is separated from the sock tube 22, and then the piston rod of the first cylinder 36 pushes the positioning hook 351 of the pulling member 35 to release the cuff of the sock 9, and at the same time the third moving mechanism 42 drives the ejection rod 45 to reset, completing the sock taking action.
[0055] The far-infrared positioning sock-wearing jig 5, the manipulator double-claw fixture, the material discharging rack, the cylinder printer and the sock-removing device provided in this embodiment can replace manual work to complete all the sock-taking and printing actions, and the personnel do not need to work for a long time in a high-temperature environment. By using the infrared positioning sock-wearing jig 5, the knitted socks can be put on the sock tube 22 in advance, and then the sock tube 22 with the socks 9 put on can be inserted into the material discharging rack to complete a large number of socks. It replaces the manual work of operating the sock-wearing calibration on the printing press, and the printing press is not occupied throughout the process. The manual work can be done in advance. The socks 9 can be put on efficiently and in large quantities, and the machine can be put into printing operations at all times, and the production capacity is not affected by manual operation; at the same time, this structural design conforms to humanized operation. According to the height of the operator, the mechanism can be adjusted in height and angle, and the socks can be put on in a completely ergonomic way, and long-term use will not cause occupational injuries. This design realizes the practicability of the cylinder printer in operation and feeding, and will develop towards full automation in the future.
[0056] By adopting the above-mentioned design scheme, the beneficial effects of the utility model are: the first moving mechanism 32 and the second moving mechanism 33 drive the hook member 35 to move back and forth, and the first cylinder 36 drives the positioning hook 351 to rotate and hook the cuff of the sock 9; at the same time, the third moving mechanism 42 and the fourth moving mechanism 43 drive the ejection rod 45 to move back and forth, so that the synchronous displacement of the sock 9 can be maintained to avoid the problem of wrinkles; by providing the hook assembly 3, the sock cover of the sock 9 can be opened instead of the worker, which is convenient for quickly taking off the sock 9, and the production efficiency is relatively high.
