[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the present invention provides a curling mechanism for a sock packing machine, which solves the problems raised in the above-mentioned background technology.

[0007] (II) Technical solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a curling mechanism for a sock baling machine, comprising a first electric push rod and a second electric push rod installed on a frame, the first electric push rod being arranged above the second electric push rod, the bottom end of the first electric push rod being fixedly connected to a servo motor, a sock clamping mechanism being arranged below the servo motor, the output end of the servo motor being connected to the sock clamping mechanism, a lifting plate being arranged below the sock clamping mechanism, the top end of the second electric push rod being fixedly connected to the lifting plate, the top of the lifting plate being fixedly connected to two sock rolling half plates, the two sock rolling half plates being arranged opposite to each other, so that a sock rolling space is formed between the two sock rolling half plates, and a vertical seam for socks to pass through is formed between the vertical sides of the two sock rolling half plates.

[0009] Preferably, anti-abrasion rounded corners are provided on the outer side of the vertical edge of the sock-rolling half plate, and guiding rounded corners are provided at the top of the vertical edge of the sock-rolling half plate.

[0010] Preferably, the sock-clamping mechanism includes a top plate, two clamping rods, two sliders, a housing, a sliding rod, and two springs. A housing is fixedly connected to the center of the top plate. The top of the housing is fixedly connected to a servo motor. A sliding rod arranged along the length direction of the housing is provided inside the housing. Both ends of the sliding rod are fixedly connected to the housing. Two sliders are slidably fitted on the sliding rod. The springs are sleeved on the sliding rod. One end of each spring is fixedly connected to a slider, and the other end of each spring is fixedly connected to the housing. A clamping rod is fixedly connected to the bottom end of each slider. The two clamping rods can clamp and fix the socks under the action of the springs.

[0011] Preferably, both the top plate and the lifting plate are circular, and the axis of the top plate coincides with the axis of the lifting plate.

[0012] Preferably, an anti-slip layer is fixedly connected to the outer surface of the clamping rod.

[0013] Preferably, a packing mechanism for packing the sock rolls in the sock-rolling space is further included. The packing mechanism includes a paper strap, a wind-receiving piece, an annular air duct, a blowing air pipe, an air pump, an annular blowing air outlet, a limiting cylinder, and a placing platform. A limiting cylinder is fixedly connected to the bottom of the lifting plate. The diameter of the limiting cylinder is the same as that of the lifting plate. An annular air duct is arranged outside the limiting cylinder. An annular blowing air outlet is provided at the top of the annular air duct. A blowing air pipe is fixedly connected to one side of the annular air duct. The end of the blowing air pipe far from the annular air duct is fixedly connected to the air pump.

When the air pump is turned on, through the setting of the blowing air pipe and the annular air duct, the annular blowing air outlet blows air upward. The wind blows on the wind-receiving piece, causing the paper strap to rise along the limiting cylinder and the sock-rolling half plate. At the same time, the second electric push rod contracts to drive the sock-rolling half plate to descend, so that the paper strap is sleeved outside the sock roll. After the sock roll loses the limitation of the sock-rolling half plate, it will become fluffy and larger, causing the sock roll to tighten the paper strap to complete the packing.

[0016] (III) Beneficial effects

[0017] The present invention provides a curling mechanism for a sock packing machine, which has the following beneficial effects:

[0018] 1. When the curling mechanism used on the sock packing machine is used, one end of the sock openings of the two socks is clamped between the two supporting rods and fixed, and then the first electric push rod is extended to drive the clamping rod and the two socks to descend, and the two socks are put into the vertical seams on both sides of the two sock rolling half plates, and then the servo motor is turned on, and the servo motor drives the clamping mechanism to rotate, so that the two socks are rolled in the sock rolling space, and the two socks can be synchronously wound conveniently and quickly, and the winding is quick and simple, and the sock rolls wound in the two symmetrical winding methods are more beautiful and have a good use effect.

[0019] 2. The curling mechanism used in the sock packing machine can clamp and fix the socks between the two supporting rods through the setting of the sock clamping mechanism. Through the setting of the packing mechanism, when the sock rolling work is completed, the air pump and the second electric push rod are turned on. When the air pump is turned on, the blowing pipe and the annular air duct are set to make the annular blowing port blow air upward. The wind blows on the wind receiving piece to make the paper belt rise along the limiting cylinder and the sock rolling half plate. At the same time, the second electric push rod contracts to drive the sock rolling half plate to descend, so that the paper belt is sleeved on the outside of the sock roll. After the sock roll loses the limit of the sock rolling half plate, it will become fluffy and larger, so that the sock roll tightens the paper belt to complete the packaging, and then you only need to take the packaged sock roll down along the clamping rod, which is very convenient to use.
