A screw rod is connected to the inside of the machine base by means of internal threads. Baffles are fixedly connected to both sides of the base. Both ends of the screw rod are rotatably connected to the baffles. One end of the screw rod is also connected to a motor. A controller is also provided on the machine base. A plurality of load-carrying platforms are connected to an elliptical transmission chain. An infrared emitter I is provided at the printing station, and an infrared emitter II is provided on the outer auxiliary guide rail.

[0004] When socks need to be printed on both sides, usually after printing on one side of the socks, manual turning is carried out before printing again. During continuous production, the manual turning operation is cumbersome and the efficiency is low. Summary of the Utility Model

[0005] In order to solve the problem that the manual turning operation is cumbersome and the efficiency is low when turning the socks for printing, the present application provides an automatic unlocking mechanism for a double-sided printing and turning device for socks.

[0006] The automatic unlocking mechanism for a double-sided printing and turning device for socks provided by the present application adopts the following technical solutions:

[0007] An automatic unlocking mechanism for a double-sided printing and turning device for socks includes a frame. A driving cylinder is arranged on the frame. A mounting frame is slidably mounted on one side of the driving cylinder on the frame. The mounting frame is connected to one end of the piston rod of the driving cylinder. A fixed frame is arranged on one side of the mounting frame on the frame. A rotating shaft is rotatably mounted on the fixed frame. A turning plate for sleeving the socks is arranged on one side of the rotating shaft. A rotating member for driving the rotating shaft to rotate is arranged on the mounting frame. A limiting member for limiting the rotating shaft is arranged on the fixed frame.

[0008] By adopting the above technical solution, the socks are placed on the flap for printing. When printing on one side is completed, the driving cylinder drives the mounting frame to slide, driving the rotating member to move to one side of the rotating shaft. The rotating member drives the rotating shaft to rotate and then drives the flap to rotate to turn over. The limiting member limits the rotating shaft, and then the other side of the socks is printed. The socks are automatically turned over in continuous production, which is convenient to operate and efficient.

[0009] Optionally, the rotating member includes a motor and a rotating block, the motor is arranged on the mounting frame, the rotating block is arranged at the output shaft of the motor, a clamping block is arranged at one end of the rotating shaft facing the mounting frame, the limiting member is located at the clamping block, and the rotating block is provided with a clamping groove for clamping the clamping block.

[0010] By adopting the above technical solution, when the rotating block moves to one side of the clamping block with the mounting frame, the clamping block is located at the clamping groove of the rotating block. At this time, the motor drives the rotating block to rotate and then drives the clamping block to rotate. At this time, the clamping block drives the rotating shaft and then drives the flap to rotate and flip over. After the flipping is completed, the rotating block is separated from the clamping block. At this time, the limit piece limits the clamping block, and the flap is not easy to rotate during printing.

[0011] Optionally, the limit member includes a limit frame, a support frame is provided on the fixed frame, the rotating shaft is rotatably installed on the support frame, the limit frame is slidably installed on one side of the support frame, a limit hole is provided on the limit frame, the clamping block is slidably connected to the limit frame at the limit hole, and a reset member for pushing the limit frame to slide is provided on the support frame.

[0012] By adopting the above technical solution, when the rotating block moves toward one side of the clamping block, the rotating block first presses against the limit frame to slide, and at the same time, one end of the clamping block slides out of the limit frame to the clamping groove of the rotating block. When the rotating block moves back to its position, the reset part pushes the limit frame to slide back to limit the clamping block, and the limiting operation is more convenient.

[0013] Optionally, the reset member includes a sliding rod and a reset spring, the sliding rod is arranged on the support frame, the limit frame is slidably connected to the sliding rod, the reset spring is sleeved on the sliding rod and one end of the reset spring is connected to the support frame, and the end of the reset spring facing away from the support frame is connected to one side of the limit frame.

[0014] By adopting the above technical solution, when the rotating block slides, it pushes the limit frame to slide. At this time, the reset spring is compressed. When the rotating block returns and disengages from the clamping block, the reset spring pushes the limit frame to slide back, and the driving operation is more convenient.

[0015] Optionally, the clamping block is located on a side facing the mounting frame and is provided with grooves on both sides, and the rotating block is provided with cutouts on both side lines of the clamping groove opening.

[0016] By adopting the above technical solution, when the rotating block moves, the cutting groove side of the clamping block enters the clamping groove along the notch of the clamping groove of the rotating block, reducing the problem of wear caused by the impact between the rotating block and the clamping block.

[0017] Optionally, a positioning block is arranged on one side of the mounting frame facing the fixed frame, and a positioning groove for embedding the positioning block is arranged on one side of the fixed frame.

[0018] By adopting the above technical solution, when the mounting frame moves to one side of the fixed frame, the positioning block is located at the positioning groove, and the position between the mounting frame and the fixed frame is fixed, facilitating the rotation of the rotating block to drive the rotating shaft.

[0019] Optionally, a sliding rail is arranged on the frame, a moving frame is slidably mounted on the frame along the sliding rail, the fixed frame is arranged on the moving frame and is slidably connected with the moving frame, and a buffer spring is arranged between the moving frame and the fixed frame.

[0020] By adopting the above technical solution, the fixed frame and the moving frame are elastically connected by the buffer spring, reducing the probability of deformation caused by stress between the moving frame and the sliding rail.

[0021] Optionally, a rotating ring is rotatably mounted on one side surface of the limiting frame facing the mounting frame, and an inclined groove is arranged on the rotating ring along the circumferential direction of the rotating ring.

[0022] By adopting the above technical solution, when the rotating block abuts against one side surface of the limiting frame, one end of the rotating block is located at the inclined groove of the rotating ring, reducing the wear caused to the limiting frame when the rotating block rotates.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The sock is sleeved on the turning plate for printing. After one side is printed, the driving cylinder drives the mounting frame to slide, driving the motor to move to one side of the rotating shaft. The rotating block pushes the limiting frame to drive the rotating shaft to rotate, thereby driving the turning plate to rotate for turning over. After the rotating block returns to its position, the limiting frame limits the clamping block, and then the other side of the sock is printed, automatically turning over during continuous production, with convenient operation and high efficiency;

[0025] 2. When the rotating block slides, it pushes the limiting frame to slide. At this time, the return spring is compressed. When the rotating block returns and disengages from the clamping block, the return spring pushes the limiting frame to slide back to its position, and the driving operation is relatively convenient;

[0026] 3. One end of the rotating block is located at the inclined groove of the rotating ring, and the wear caused to the limiting frame when the rotating block rotates is small. Description of the Drawings

Detailed Description of the Embodiment

[0033] The following further describes the present application in detail with reference to the drawings.

[0034] The embodiment of the present application discloses an automatic unlocking mechanism of a double-sided printing and flipping device for socks. Referring to Figure 1 , it includes a frame 1, on which a driving cylinder 11 is horizontally arranged. On one side of the piston rod of the driving cylinder 11 on the frame 1, a mounting frame 12 is slidably installed, and one side of the mounting frame 12 is connected to one end of the piston rod of the driving cylinder 11.

[0035] Referring to Figure 1 , on the frame 1, on the side of the mounting frame 12 away from the driving cylinder 11, a slide rail 13 is horizontally arranged. The slide rail 13 is perpendicular to the axis direction of the piston rod of the driving cylinder 11. A moving frame 14 is slidably installed on the slide rail 13. A fixed frame 15 is arranged on the moving frame 14. A support frame 16 is arranged on the fixed frame 15. A rotating shaft 17 is rotatably installed on the support frame 16. A flap 18 is arranged at one end of the rotating shaft 17 away from the mounting frame 12. Socks are sleeved on the flap 18 for printing.

[0036] Referring to Figure 2 and Figure 3, a rotating member 2 is provided on the mounting bracket 12. The rotating member 2 includes a motor 21 and a rotating block 22. The motor 21 is provided on the mounting bracket 12. The motor 21 is a stepper motor 21. The rotating block 22 is provided at the output shaft of the motor 21 and is located on the side facing the fixed bracket 15. A clamping block 171 is provided at the end of the rotating shaft 17 away from the flap 18. The clamping block 171 is flat and square. A clamping groove 221 is formed at the end of the rotating block 22 away from the motor 21. When it is necessary to turn the flap 18 over, the driving cylinder 11 drives the mounting bracket 12 to slide until the rotating block 22 is located at the clamping block 171. At this time, the clamping block 171 is located at the clamping groove 221 of the rotating block 22. The motor 21 drives the rotating block 22 to rotate, thereby driving the clamping block 171 to rotate. The clamping block 171 drives the rotating shaft 17 to rotate, thereby driving the flap 18 to rotate for turning over.

[0037] Referring to Figure 2 and Figure 3 , a limiting member 3 is provided on the support bracket 16. The limiting member 3 includes a limiting frame 31. A reset member 4 is provided on the support bracket 16 on one side of the limiting frame 31. The reset member 4 includes a sliding rod 41 and a reset spring 42. Four sliding rods 41 are provided and are horizontally arranged on one side surface of the support bracket 16. The limiting frame 31 is vertically arranged and the limiting frame 31 is slidably mounted on the sliding rod 41. A limiting bolt 411 is provided at one end of the sliding rod 41 and on one side of the limiting frame 31.

[0038] Referring to Figure 2 and Figure 3 , the reset spring 42 is sleeved on the sliding rod 41. One end of the reset spring 42 is connected to the support bracket 16. The end of the reset spring 42 away from the support bracket 16 is connected to one side surface of the limiting frame 31. A limiting hole 311 is formed at the middle position of the limiting frame 31. The clamping block 171 is slidably connected to the limiting frame 31 at the limiting hole 311. A rotating groove 172 is provided at one side of the rotating shaft 17 where the clamping block 171 is located. When the rotating block 22 moves, one end of the rotating block 22 pushes the limiting frame 31 to slide to the rotating groove 172 of the rotating shaft 17. At this time, the reset spring 42 is compressed, and the clamping block 171 is disengaged from the limiting frame 31 to the clamping groove 221 of the rotating block 22. The rotating block 22 rotates, driving the rotating shaft 17 to rotate. When the rotating shaft 17 rotates and turns over, the driving cylinder 11 drives the mounting bracket 12 to slide back to its original position. The rotating block 22 is separated from the clamping block 171. At this time, the reset spring 42 pushes the limiting frame 31 to slide back to its original position to limit the clamping block 171.

[0039] Referring to Figure 2 and Figure 3 , a cutting groove is provided at the side of the clamping block 171 in the vertical direction. Cuts are provided at the opposite two side edges at the opening of the clamping groove 221 of the rotating block 22. When the rotating block 22 moves, one side of the cutting groove of the clamping block 171 enters the clamping groove 221 along the cut of the clamping groove 221 of the rotating block 22.

[0040] Refer to Figure 2 and Figure 3 On one side of the limit frame 31 facing the mounting bracket 12, a rotating ring 312 is rotatably mounted. An inclined groove is provided on the rotating ring 312 along the circumferential direction of the rotating ring 312. When one end of the rotating block 22 abuts against one side of the limit frame 31, one end of the rotating block 22 is located at the inclined groove of the rotating ring 312, reducing the wear caused to the limit frame 31 when the rotating block 22 rotates.

[0041] Refer to Figure 2 and Figure 3 On one side of the mounting bracket 12 facing the fixed bracket 15, a positioning block 121 is provided. On one side of the fixed bracket 15 facing the mounting bracket 12, a positioning groove 151 is provided. When the mounting bracket 12 moves to one side of the fixed bracket 15, the positioning block 121 is located at the positioning groove 151, and the relative position between the mounting bracket 12 and the fixed bracket 15 is fixed.

[0042] Refer to Figure 4 , The moving frame 14 is slidably connected to the fixed frame 15. A buffer spring 141 is provided on the moving frame 14. One end of the buffer spring 141 is connected to the fixed frame 15. The fixed frame 15 and the moving frame 14 are elastically connected through the buffer spring 141, reducing the probability of deformation of the moving frame 14 and the slide rail 13 due to stress.

[0043] The implementation principle of the automatic unlocking mechanism of the double-sided printing turning device for socks in the embodiment of the present application is as follows: The driving cylinder 11 drives the mounting bracket 12 to move. At this time, the rotating block 22 on one side of the motor 21 pushes the limit frame 31 to slide, and the return spring 42 is compressed. The motor 21 drives the rotating block 22 to rotate, and the rotating block 22 drives the clamping block 171 to rotate, thereby driving the rotating shaft 17 to rotate, turning the turning plate 18 over. After the turning is completed, the driving cylinder 11 drives the mounting bracket 12 to return to its original position, and the return spring 42 returns, pushing the limit frame 31 to limit the clamping block 171, and the rotating block 22 is separated from the clamping block 171. The motor 21 drives the rotating block 22 to reverse and return to its original position, preparing for the next turning operation.

[0044] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
