Description

Technical Field

[0001] The utility model belongs to the technical field of textile machinery, and particularly relates to a yarn changing mechanism for a spinning frame. Background Art

[0002] As the core equipment of the textile industry, the efficient and stable operation of the spinning frame is directly related to the dual improvement of production efficiency and product quality. The yarn changing mechanism of the spinning frame is an important part of the spinning frame used to automatically or manually replace full bobbins and install empty bobbins.

[0003] The existing yarn changing mechanism has the problem of being unable to simultaneously remove full bobbins and install empty bobbins. This problem directly leads to a lengthy yarn changing process, significantly slowing down the overall production rhythm, resulting in low yarn changing efficiency, and a corresponding increase in equipment operating costs, reducing the company's economic benefits.

[0004] Therefore, in order to solve the above problems, it is necessary to design a yarn changing mechanism for a spinning frame. Utility Model Content

[0005] The utility model aims to provide a yarn changing mechanism for a spinning frame, so as to solve the technical problem that full bobbins cannot be taken out and empty bobbins cannot be installed synchronously.

[0006] In order to solve the above technical problems, the utility model provides a yarn changing mechanism for a spinning frame, comprising:

[0007] A rotary telescopic cylinder with a connecting piece on the top;

[0008] A plurality of pipe grabbers are symmetrically arranged on both sides of the connecting piece;

[0009] The conveyor is symmetrically arranged on both sides of the rotating and telescopic cylinder, and includes: a conveyor belt;

[0010] The two conveyor belts are respectively provided with a plurality of full yarn drums and empty yarn drums;

[0011] The rotary telescopic cylinder is adapted to move each tube grabber to a corresponding position by telescoping to grab a full bobbin on one conveyor belt and an empty bobbin on the other conveyor belt; and

[0012] The rotary telescopic cylinder is suitable for exchanging the positions of the full yarn bobbin and the empty yarn bobbin through rotation.

[0013] Furthermore, the two sides of the connector are symmetrically provided with extended square tubes;

[0014] Each of the pipe grabbers is symmetrically arranged on two extended square tubes.

[0015] Furthermore, the conveyor belt is provided with a plurality of fixed discs;

[0016] contact the adjacent fixed disk; wherein

[0017] Each of the full yarn bobbins and each of the empty yarn bobbins are arranged on the corresponding fixed disk.

[0018] Furthermore, positioning members are provided at the center tops of the respective fixed disks; wherein

[0019] Each of the full yarn bobbins and each of the empty yarn bobbins are sleeved on the corresponding positioning members.

[0020] Furthermore, the grippers on the lengthened square tube are arranged at equal intervals; wherein

[0021] The distance between two adjacent grippers is the same as the distance between the positioning members on the fixed disk after adjacent contact.

[0022] The beneficial effects of the present utility model are as follows:

[0023] (1). Before the yarn changing operation starts, ensure that the full yarn bobbins and empty yarn bobbins on the two conveyors are neatly arranged and in a position easy to grip. Control the rotary telescopic cylinder to start working. Drive each gripper to move to the corresponding positions on the two side conveyors through the telescopic function. Grip the full yarn bobbins and empty yarn bobbins through the grippers. After the gripping is completed, the rotary telescopic cylinder performs a rotation operation to swap the positions of the gripped full yarn bobbins and empty yarn bobbins above the opposite side conveyor. The positions of the full yarn bobbins and empty yarn bobbins are automatically swapped. The rotary telescopic cylinder again moves the gripper to a suitable height from the conveyor belt through the telescopic function, and releases the full yarn bobbins and empty yarn bobbins to the corresponding conveyor belts through the grippers. The conveyor starts to work, conveys the empty yarn bobbins to the corresponding positions of the spinning frame for replacement, and at the same time conveys the full yarn bobbins to the next process for subsequent processing. Through the above steps, the rapid replacement of the full yarn bobbins and empty yarn bobbins is achieved through automated operation, significantly shortening the yarn changing time and improving the production efficiency.
