Description

Technical Field

[0001] The utility model relates to the technical field of sock turning devices, in particular to an automatic sock turning device for a sock knitting machine. Background Art

[0002] A sock knitting machine is a machine device for producing socks, and is processed by a plurality of device assembly lines during the processing.

[0003] During the production of socks, shaping is required. The shaping is sleeved on a bracket with a shape adapted to the shape of the socks. After shaping, the socks need to be turned over. This process is usually completed by workers, which is rather cumbersome in the assembly line production. Therefore, we propose an automatic sock turning device for a sock knitting machine to solve the existing problems. Summary of the Utility Model

[0004] The purpose of the utility model is to propose an automatic sock turning device for a sock knitting machine aiming at the problems existing in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an automatic sock turning device for a sock knitting machine, including a mounting frame,

[0006] A sock turning structure, including a mounting seat located below the mounting frame, a sock support located inside the mounting seat, a rotating shaft located at both ends of the sock support and rotatably installed inside the mounting seat, a gear located on one side of the rotating shaft, a motor located at the lower end of the mounting frame, a screw rod located at the output end of the motor, a nut rotatably sleeved on the outer wall of the screw rod, a push plate located at the lower end of the nut, push bars located on one side outer wall of the push plate and symmetrically distributed on both sides of the sock support, a hydraulic rod located on one side of the push bar, a stroke plate located at the telescopic end of the hydraulic rod, and a rack located at the lower end of the stroke plate and meshing with the gear;

[0007] A sock removing structure, including an air pump fixed on one side of the mounting frame, a hose located at the output end of the air pump, a sleeve plate installed in communication with the hose, a support frame located outside the sleeve plate, and an air groove opened inside the sleeve plate.

[0008] When using an automatic sock turning device for a sock knitting machine in this solution, after the sock support moves to the designated position, the hydraulic rod operates to drive the stroke plate to move, driving the rack to push the gear. The gear drives the rotating shaft to rotate, and then drives the sock support to rotate. During this process, the torsion spring is stressed and twisted. The top of the sock support corresponds to the sleeve plate. The motor operates to drive the screw to rotate. Since the nut slides on the guide rail through the slider, obtaining sliding guidance, when the screw rotates, the nut is pushed to achieve lateral movement, driving the push plate and the push bar to move. The push bar fits and moves along the sock support, squeezing the opening of the sock. The sock is stressed and shrinks, and enters onto the sleeve plate. When it completely enters the outer wall of the sleeve plate, it continues to be squeezed, causing the opening of the sock to face and fit the limit plate. At this time, the sock turning structure resets, and the motor drives the mounting shaft to rotate, driving the limit ring to rotate. The limit ring drives the sleeve plate to flip. The air flow conveyed by the air pump enters the air groove through the hose. Under the output of the high-pressure gas, the sock is blown and falls onto the conveyor belt, thus realizing the turning of the sock core, facilitating subsequent processing, and avoiding the operation of manual sock turning.

[0009] Preferably, one end of the air groove penetrates the sleeve plate, and the end penetrating the sleeve plate corresponds to the sock support. The air flow conveyed by the hose is conveyed through the air groove and discharged through the opening.

[0010] Preferably, a limit ring is provided on the outer wall of the sleeve plate, and a mounting shaft is rotatably installed inside the support frame at the lower end of the limit ring. The limit ring plays a supporting role for the mounting shaft and at the same time plays a limiting role for the sock sleeved on the sleeve plate.

[0011] Preferably, a motor with an output end connected to the mounting shaft is provided at one end of the support frame. During the use of the motor, it drives the mounting shaft to rotate, driving the sleeve plate connected thereto to flip.

[0012] Preferably, a torsion spring is sleeved outside the rotating shaft, and both ends of the torsion spring are respectively connected to the mounting seat and the outer wall of the rotating shaft. When the torsion spring rotates, when the rotating shaft rotates and loses the acting force, through the torsional elasticity of the torsion spring, the rotating shaft is driven to reset.

[0013] Preferably, a guide rail is provided on the inner wall of the upper end of the mounting frame, and a slider is provided at the upper end of the nut. The slider is slidably sleeved on the outer wall of the guide rail. The slider slides on the outer wall of the guide rail to provide lateral sliding guidance for the nut.

[0014] Preferably, a conveyor belt is provided below the air pump, and the conveyor belt is located below the support frame. The dropped sock is received by the conveyor belt and transported for loading.

[0015] Preferably, a bearing support is provided on the inner wall of the upper end of the mounting frame, and one end of the screw is rotatably inserted into the inside of the bearing support. When the screw rotates, it is rotationally supported by the bearing support, improving the stability of the screw rotation.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. When the socks sleeved on the outer side of the sock support of the present utility model are shaped and moved to the sock turning structure, they are turned by the driving member, and the socks are extruded by the push bar. After the socks are stressed, they are separated from the support, and the socks are pushed to the outside of the sleeve plate. During this process, because the force is applied to push from the opening of the socks, the socks are turned inside out, and the turned-inside-out socks are blown away by the negative pressure blowing rotating shaft, reducing the problems of cumbersome manual operation and low efficiency in the process of assembly line processing.
