[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] A turning device for producing stockings, such as Figures 1-3 As shown, the machine includes a processing table 1, with a mounting block 2 slidably connected to the upper surface of the processing table 1. The upper surface of the processing table 1 is provided with a driving device for moving the mounting block 2. Two symmetrically distributed stocking posts 3 are fixedly connected to the upper surface of the mounting block 2. The surface of the stocking posts 3 is provided with several annular array-distributed receiving grooves, and several array-distributed universal ball bearings 22 are provided on the inner wall of the receiving grooves.

[0022] The upper end face of the sock post 3 is provided with a slot 4. The side walls on both sides of the sock post 3 are provided with through grooves 5 that communicate with the outside. The through grooves 5 communicate with the slot 4. The upper end face of the processing table 1 is provided with guide ramps 6 on both sides. The guide ramps 6 correspond to the positions of the sock posts 3 on both sides. The processing table 1 is provided with collection boxes on both sides that correspond to the positions of the guide ramps 6, so as to facilitate the collection of socks loaded and unloaded by the guide ramps 6.

[0023] A bracket 7 is fixedly connected to the upper end face of the processing table 1. A liftable horizontal plate 8 is provided on the bracket 7. A lifting device for driving the horizontal plate 8 to rise and fall is provided on the bracket 7. A plug rod 9 is provided on the lower end face of the horizontal plate 8 and is rotatably connected to it. A motor 1 for driving the plug rod 9 to rotate is installed on the side wall of the horizontal plate 8. The motor 1 is a servo motor. One end of the plug rod 9 is connected to the output shaft of the motor 1. The plug rod 9 corresponds to the position of the slot 4. The width of the slot 4 is greater than the diameter of the cross section of the plug rod 9, so that the plug rod 9 can smoothly extend out of the slot 4 when rotating.

[0024] The driving device includes a gear 10 that is rotatably connected to the upper end face of the processing table 1. A second motor 11 for driving the gear 10 to rotate is installed inside the processing table 1. The second motor 11 is a servo motor. The output shaft of the second motor 11 is connected to the shaft of the gear 10. A rack 12 that meshes with the gear 10 is fixedly connected to the side wall of the processing table 1.

[0025] Two symmetrically distributed vertical plates 18 are fixedly connected to the upper end face of the processing table 1. A limit rod 19 is fixedly connected between the two vertical plates 18. A limit hole is opened on the mounting block 2 for the limit rod 19 to pass through. The gear 10 and the vertical plates 18 are staggered from the guide slope 6.

[0026] The lifting device includes a mounting bracket 13 fixed to the upper end face of the support 7. A lead screw 14 is rotatably connected to the inner wall of the mounting bracket 13. A motor 3 for driving the lead screw 14 to rotate is installed on the mounting bracket 13. A nut seat 15 is sleeved on the lead screw 14. Fixing rods 16 are fixedly connected to both sides of the nut seat 15. Connecting rods 17 are fixedly connected to the lower end face of both fixing rods 16. A through hole is opened on the support 7 for the connecting rods 17 to pass through. One end of the connecting rod 17 passing through the through hole is fixedly connected to the upper end face of the horizontal plate 8.

[0027] An air pump 20 is installed on the upper end of the horizontal plate 8. An air pump 20 is provided with an air hose 21 connected to it at one end. An air nozzle is opened at the end of the insertion rod 9 away from the horizontal plate 8. An installation groove communicating with the air nozzle is opened in the insertion rod 9. The other end of the air hose 21 passes through the installation groove and is connected to the air nozzle. The length of the air hose 21 is longer than the length of the insertion rod 9, so that the normal use of the air hose 21 will not be affected when the insertion rod 9 rotates.

[0028] Working principle: When socks need to be turned inside out, the sock to be turned inside out is placed on one of the sock-covering posts 3. Then, the gear 10 is driven to rotate by the motor 2 11. Since the gear 10 meshes with the rack 12 on the side wall of the mounting block 2, the rotation of the gear 10 can drive the mounting block 2 to move through the rack 12, so that the sock-covering post 3 with the sock on it comes to the processing station. At this time, the slot 4 and the insertion rod 9 are in the same position. The motor 2 11 is turned off so that the mounting block 2 stays in the current position. At this time, the insertion rod 9 is in a vertical state.

[0029] Then, the motor drives the lead screw 14 to rotate, which in turn drives the fixed rods 16 and connecting rods 17 on both sides to move downwards via the nut seat 15. The connecting rod 17 then drives the insertion rod 9 downwards via the cross plate 8, inserting it into the slot 4 from above. At this time, the end of the sock covers the opening of the slot 4. As the insertion rod 9 continues to penetrate deeper into the slot 4, it will also drive the sock to be inserted into the slot 4 from the end. During the insertion process, the sock will change to a state of being fitted onto the insertion rod 9, achieving a flip-over. When the insertion rod 9 is inserted to the point where the end contacts the bottom wall of the slot 4, the sock can completely detach from the outer surface of the sock post 3 and transfer to be fitted onto the insertion rod 9. During this process, the universal ball bearing 22 will roll along the inner wall of the sock, reducing the contact between the sock and the sock post 3. The friction between them makes the socks come off more smoothly. After the socks are turned inside out, the motor drives the insertion rod 9 to rotate towards the side close to the guide slope 6. The end of the insertion rod 9 can pass through the through groove 5 and pull the sock out of the slot 4 together. At this time, the ends of the insertion rod 9 and the sock are facing the guide slope 6. Then, the air pump 20 and the air hose 21 blow air into the air nozzle, so that the turned-out socks are detached from the insertion rod 9 by their own weight and the airflow blown out of the air nozzle and fall onto the guide slope 6. The socks are then fed through the slope of the guide slope 6. The insertion rod 9 itself has a small diameter and does not fully open the sock, making it easier for the socks to come off. In addition, the end of the insertion rod 9 is arc-shaped, which makes the rotation of the insertion rod 9 smoother and avoids collision with the bottom wall of the slot 4.

[0030] After the material is unloaded, the first motor drives the insertion rod 9 to rotate in the opposite direction back to the vertical position. Then, the third motor drives the lead screw 14 to rotate in the opposite direction, causing the nut seat 15 to move upward. The nut seat 15 then drives the horizontal plate 8 to move upward through the fixing rod 16 and the connecting rod 17, so that the insertion rod 9 is pulled out of the slot 4 and returns to the top.

[0031] Meanwhile, during the entire flipping and unloading process, the worker can place the next sock to be flipped onto another sock-feeding post 3. After the sock flipping and unloading is completed, the motor 21 drives the gear 10 to rotate in the opposite direction, causing the rack 12 and the mounting block 2 to move in the opposite direction, so that the other sock-feeding post 3 comes to the bottom of the insertion rod 9 for flipping. This process is repeated. When processing the sock on a particular sock-feeding post 3, the insertion rod 9 rotates and tilts towards the guide ramp 6 on the side closer to that sock-feeding post 3 during the unloading process. The dual-station processing makes its continuity better, the flipping and unloading operation more convenient, improves the flipping efficiency of socks, and saves manpower.

[0032] As the mounting block 2 moves along with the rotation of the gear 10, it will move along the limit rod 19, making the mounting block 2 more stable during the movement.

All technical solutions falling within the scope of this utility model's concept are protected.
