Description

[0040] like Figure 1-5 As shown, the doffing machine of the present invention includes a horizontal moving mechanism 1, a vertical moving mechanism 2, and a wire receiving mechanism 3. The vertical moving mechanism 2 is disposed on the horizontal moving mechanism 1, and the horizontal moving mechanism 1 is used to drive the vertical moving mechanism 2 to move horizontally. The wire receiving mechanism 3 is disposed on the vertical moving mechanism 2, and the vertical moving mechanism 2 is used to drive the wire receiving mechanism 3 to move vertically.

[0041] The wire-connecting mechanism 3 includes multiple sets of telescopic components, a pusher assembly, and a wire-connecting cylinder. The telescopic components are hoisted and fixed on the vertical movement mechanism 2; the pusher assembly is fixed on the movable end of the telescopic components; and the wire-connecting cylinder is set on the movable end of the pusher assembly. The telescopic components are used to push the pusher assembly, and the pusher assembly is used to disengage the wire-connecting cylinder.

[0042] To prevent the velvet from being affected and damaged by gravity in the transmission structure of the wire-joining mechanism 3, the wire-joining mechanism 3 is suspended on the vertical moving mechanism 2. During operation, the velvet will not be affected by the movement of the wire-joining mechanism 3, which not only improves its service life but also improves the joining accuracy of the wire-joining mechanism 3 during replacement. At the same time, the suspension of the wire-joining mechanism 3 saves space and improves space utilization. It occupies little space and is suitable for widespread use.

[0043] In a preferred embodiment, the number of the telescopic component, the pusher component, and the wire receiving cylinder is not less than two sets, and the telescopic component, the pusher component, and the wire receiving cylinder correspond one-to-one.

[0044] To improve the adaptability of the wire feeding machine, the number of telescopic components, pusher components, and wire receiving drums shall not be less than two sets, and the telescopic components, pusher components, and wire receiving drums shall correspond one-to-one. The number of telescopic components, pusher components, and wire receiving drums shall not be limited to two, three, or four. By setting multiple telescopic components, multiple wire receiving drums can be placed, thereby improving the adaptability.

[0045] In a preferred embodiment, the telescopic component is provided with a wire-connecting base, which is mounted on the vertical movement mechanism 2, and the vertical movement mechanism 2 drives the wire-connecting base to move up and down.

[0046] Specifically, the wire splicing base is equipped with pulleys, and the vertical movement mechanism 2 is equipped with slide rails that cooperate with the pulleys. During the up-and-down sliding process of the wire splicing base, it helps to improve the stability of the wire splicing base, and the cooperation between the slide rails can also avoid the influence of lint.

[0047] In a preferred embodiment, both the telescopic component and the pusher component are driven by a pair of gears and a toothed belt, wherein one of the gears is connected to a motor, and both gears mesh with the toothed belt.

[0048] To enable the telescopic component and the pusher component to drive, a pair of gears and a toothed belt are set up. The pair of gears are connected by the toothed belt. The telescopic component first pushes out the pusher component, and then the pusher component pushes out the silk cake, thereby improving space utilization.

[0049] In a preferred embodiment, the vertical movement mechanism 2 includes a vertical plate, a vertical movement motor, a pair of transmission wheels, and a transmission belt. The vertical plate is mounted on the horizontal movement mechanism 1; the vertical movement motor is fixed on the vertical plate; the pair of transmission wheels are rotatably mounted on the vertical plate, and the output end of the vertical movement motor is connected to one of the transmission wheels; the transmission belt is mounted on the transmission wheels, and the pair of transmission wheels are connected by transmission belt. The wire connector base is fixed on the transmission belt.

[0050] To enable the wire-joining mechanism 3 to move vertically, a vertical movement motor, a pair of drive wheels, and a drive belt are provided. The vertical movement motor can be a servo motor. The vertical movement motor drives one of the drive wheels to rotate, thereby driving the drive wheel to rotate. As a result, the drive wheel located above will wrap around the drive belt, thereby enabling the wire-joining mechanism 3 to move vertically. The pair of drive wheels are arranged vertically.

[0051] In a preferred embodiment, the vertical movement mechanism 2 further includes a protective housing, which is disposed on the vertical plate, and the transmission belt is located inside the protective housing.

[0052] To further prevent the lint from affecting the transmission structure, since the vertical moving mechanism 2 is located below the lint receiving mechanism 3, the lint will fall onto the vertical moving mechanism 2. By using a pair of drive wheels and drive belts and a protective shell, the lint can be prevented from entering. Furthermore, using a pair of drive wheels and drive belts can reduce the impact of the lint and prevent transmission failure.

[0053] In a preferred embodiment, the transverse movement mechanism 1 includes a crossbeam, a rack, a gear, and a transverse movement motor. The rack is fixed on the crossbeam, and the vertical plate is slidably mounted on the crossbeam. The gear is rotatably mounted on the vertical plate and meshes with the rack. The transverse movement motor is fixed on the vertical plate, and its output end is fixedly connected to the gear.

[0054] In order to achieve the lateral movement of the wire connecting mechanism 3, a lateral movement motor is set up. The lateral movement motor can drive the gear transmission. Since the gear meshes with the rack, the wire connecting assembly 3 can slide in the lateral direction.

[0055] In a preferred embodiment, the vertical plate has a U-shaped structure and is located at the bottom of the horizontal beam 1, and is slidably connected to the vertical plate via a slide rail.

[0056] In a preferred embodiment, the vertical movement mechanism 2 further includes a mounting ring and a laser detector, wherein the mounting ring is fixed to the bottom of the vertical plate; and the laser detector is fixed to the mounting ring.

[0057] The working principle of this embodiment is as follows:

[0058] First, by setting a horizontal movement motor, the horizontal movement motor can drive gear transmission. Since the gear meshes with the rack, the vertical plate can slide in the horizontal direction. By setting a vertical movement motor, a pair of transmission wheels and a transmission belt, the vertical movement motor can be a servo motor. The vertical movement motor drives one of the transmission wheels to rotate, thereby driving the transmission wheel to rotate. As a result, the transmission wheel located above will wrap the transmission belt, thereby realizing the vertical movement of the wire connecting mechanism 3. The pair of transmission wheels are set in the vertical direction.

[0059] Next, by setting a pair of gears and a toothed belt, the pair of gears are connected by the toothed belt drive. The telescopic component first pushes out the cake pusher component, and then the cake pusher component pushes out the silk cake, thereby improving space utilization.

[0060] In addition, the hoisting mechanism 3 saves space and improves space utilization. It occupies little space and is suitable for widespread use.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
