Description

Technical Field

[0001] The utility model belongs to the technical field of textile machinery manufacturing, in particular to a double-grabbing-arm cotton grabbing machine. Background Art

[0002] The cotton plucking machine is an important machine used in textile machinery to realize the automated spinning process. It mainly includes components such as a tower body, a grabbing arm, a track, and a cotton conveying duct. The tower body is set on the track and can move along the arrangement direction of the cotton bales. The grabbing arm is set on the tower body with variable height. One or two opening and loosening beaters are set in the grabbing arm. The opening and loosening beaters rotate at high speed to grab the cotton bundles on the upper surface of the cotton bale, and then transmit them to the next process through the cotton conveying duct.

[0003] During the production process of the existing reciprocating cotton plucking machine, the working area is divided into two working areas, A and B. The turret is rotated by a reduction motor to drag the cotton plucking device to realize the transition of the working area. Each time the area is changed and the edge is turned, it takes a long time, which affects the continuous cotton supply of the cotton plucking machine.

[0004] In order to meet the needs of textile enterprises to increase cotton picking output, improve the number of bales and the mixing effect during picking under existing conditions, textile machinery manufacturers have proposed many solutions.

[0005] A Chinese patent (publication number: CN2199994Y) discloses an automatic double-arm cotton plucking machine, which has two cotton plucking arms on the tower body, which are arranged on both sides of the tower body, and the cotton plucking arms are provided with two cotton suction devices, and the cotton plucking machine is provided with two cotton feeding devices, and the two plucking arms can operate independently or simultaneously, which can improve the cotton plucking output and can grab two kinds of raw materials at the same time. However, the patent states that the raw materials grabbed by the two plucking arms are transported separately into two independent cotton conveying fans, and the use of two fans will increase energy consumption and make subsequent pipeline layout difficult.

[0006] A Chinese patent (publication number: CN217298115U) discloses a double-arm cotton plucking machine, including: a column, which is rotatably connected to a mounting plate; a supporting beam, which is fixedly connected to the mounting plate, and the two ends of the supporting beam extend symmetrically outside the mounting plate; two cotton plucking arms corresponding to the extended portion of the supporting beam are provided, and the cotton plucking arms are slidably connected to the extended portion of the supporting beam; a rotating assembly, which is used to drive the mounting plate to rotate so that the extended portion of the supporting beam is suspended and rotates around the axis of the column; a lifting assembly, which is arranged on the supporting beam, and is used to drive the cotton plucking arm to rise and fall. The lifting of the grabbing arm in this patent uses a screw structure, but it does not involve the direction of the raw materials after grabbing. This patent is an improvement on the double-arm type based on the original structure of the disc plucking machine. As we all know, the cotton plucking width of the disc plucking machine is limited, and it only operates in the circumferential direction, and the output increase is not significant.

[0007] How to design a double-arm cotton plucking machine with reasonable cotton conveying channels and cotton conveying fans, which can increase production while reducing the difficulty of subsequent pipeline layout and energy consumption, is a technical problem that needs to be solved urgently in this field.
