Technical Field

[0001] The utility model relates to the technical fields of clothing and textile, in particular to an automatic feeding device for a seam machine. Background Art

[0002] The sock seam machine is a special device for socks. The main defects of the existing sock seam machine are that although there are adjustments for sock clamping and lifting during the sock guiding process, generally speaking, the structure is not perfect and the failure rate is relatively high. On the other hand, for the existing seam machine, the motors used in the two processes of sock transmission and sock head stitching are installed separately at multiple locations. This installation method not only occupies a large space, but also the irregular vibrations generated by multiple motors have poor stability for the overall seam machine, which will affect the quality of the seam. Therefore, this application specifically discloses an automatic feeding device for a seam machine. Content of the Utility Model

[0003] The purpose of the utility model is to solve the existing problems and provide an automatic feeding device for a seam machine.

[0004] The utility model is realized through the following technical solutions: an automatic feeding device for a seam machine, including a ring conveyor. A plurality of support frames are arranged on the ring of the ring conveyor. A sock sleeving mechanism is arranged outside the support frames. The rod seat of the sock sleeving mechanism is connected to one side of the frame. A first motor is installed at one end of the frame far from the ring conveyor. The output shaft of the first motor is connected to a feeding machine. A sock withdrawing mechanism is arranged outside the feeding machine.

[0005] As a further improvement of the above solution, the feeding machine includes a turntable. The turntable is sleeved on the output shaft of the first motor. A plurality of telescopic members are installed on one side of the turntable. The telescopic members drive the displacement of a cylinder sleeve. The cylinder sleeve is sleeved on a support rod. One end of the support rod is connected to the turntable, and the other end of the support rod is connected to an end sleeve. Support plates are symmetrically arranged on the cylinder sleeve. The first motor drives the turntable to rotate, and drives the cylinder sleeve and the end sleeve to rotate. In addition, the cylinder sleeve is displaced by the telescopic members through a connecting rod. The cylinder sleeve is displaced on the support rod close to or away from the end sleeve to facilitate smoothing and removing the pantyhose.

[0006] As a further improvement to the above solution, the sock - sleeving mechanism includes a rod base symmetrically arranged at the end of a guide rod. A slider is slidably sleeved on the guide rod. Sector gears are symmetrically and rotatably engaged with the outer side of the slider. One end of an arm rod is integrally connected to the outer end of the sector gear. A fixed clamp plate is arranged at the other end of the arm rod, and a movable clamp plate is rotatably arranged on the inner side thereof. The movable clamp plate is connected to a rotating rod, and the rotating rod is rotatably sleeved at the other end of the arm rod. The inserted - sleeve end of the rotating rod is sleeved on one end of a rotating plate, and the other end of the rotating plate is rotatably connected to one end of a rotating rod.

A first tension spring is connected between the middle of the arm rod and a swing rod, and the swing rod is connected to the slider. When the pantyhose sleeved on the support frame moves to the position of the rod base, the slider moves on the guide rod, causing the outer end of the arm rod to approach the mouth of the pantyhose. The rotation of the arm rod with a smaller opening drives the rotation of the rotating rod, the rotating plate, and the rotating rod, and then drives the rotation of the clamp plate, cooperating with the fixed clamp plate to clamp the pantyhose. When the slider moves back, the pantyhose is sleeved on the cylinder sleeve.

[0007] As a further improvement to the above solution, the support frame includes a servo - motor installed on the annular conveyor. Support arms I and II are symmetrically sleeved on the output shaft of the servo - motor. One end of support arm I is connected to a gear, and the gear meshes with the teeth at the end of support arm II.

A lining is sleeved on the support rod, and one end of the lining is rotatably connected to the block pad. A second tension spring is connected between support arms I and II through a hanging rod. By driving the gear to rotate with the servo - motor, the gear drives the rotation of support arm I. At the same time, the rotation of the gear and the inner end of support arm II engaged therewith drive support arm II to rotate synchronously, thereby causing support arms I and II to open, and the closing is reset by the second tension spring.

[0008] As a further improvement to the above solution, an upper guide ring and a lower guide ring are respectively arranged on the outer side of the annular conveyor, and a pick - up rod is arranged at one end of the upper guide ring and the lower guide ring close to the sock - sleeving mechanism in a matching manner. One end of the pick - up rod is connected to a rotating wheel, and the rotating wheel is driven by a motor III. The motor III is installed on a support. By driving the pick - up rod to rotate with the motor III, the sock tube guided from the upper guide rod and the lower guide rod is picked up and led to the end of the end sleeve, so that the sock head is sucked into the hole of the end sleeve.

[0009] As a further improvement to the above solution, the sock - removing mechanism includes a wheel disc rotatably connected to a wheel frame through a shaft rod, and the wheel disc is connected to a motor II through the shaft rod. The motor II is installed on the wheel frame. The wheel frame is movably installed on a frame plate through a cylinder. The frame plate is connected to the machine frame. Guide rods are arranged on both sides of the cylinder. By driving the wheel frame to approach or move away from the cylinder sleeve with the cylinder, the rotation of the wheel disc is used to separate the sock body from the cylinder sleeve and sleeve it, and at the same time, the wheel frame is restricted by the guide rods to ensure that the wheel disc is aligned with the cylinder sleeve.

[0010] The utility model has the following advantages compared with the prior art: it has a compact structure, a reasonable and novel design idea. The pantyhose is supported by the support frame on the ring conveyor. The slider slides on the guide rod, and the moving clamping plate hooks the mouth of the pantyhose. When the slider moves back, the pantyhose is sleeved on two barrel sleeves on the same plane. At the same time, the toe of the pantyhose is sucked into the inner hole of the end sleeve. With the rotation of the wheel disc, the pantyhose is smoothly sleeved on the barrel sleeve. The rotation of the turntable drives the barrel sleeve to rotate to the platform for sewing the pantyhose. By replacing manual operation with mechanical processing, the work efficiency is improved, the labor cost is saved, and greater value is created for the enterprise. BRIEF DESCRIPTION OF THE DRAWINGS
