Problems solved by technology

[0002] At present, there are two types of extruders. One is to clamp the middle part of the bobbin with an airbag for extubation and doffing. There are also different degrees of damage; there is also a gripper that clamps the top of the bobbin for pulling and doffing. This kind of gripper clamps and releases the top of the bobbin for a long time, so that the bobbin The top of the tube is unfavorable, and the position of the clamped bobbin cannot be wound, which reduces the spinning time and increases the number of doffing times

Embodiment Construction

[0012] When the doffing starting arm carries the tube puller of the present invention so that the left and right support pins (11) are inserted into the hole on the top of the bobbin when they are combined, the overcoat (1) will move upward under the action of the starting arm, But because the self weight of inner cover (10) adds the effect of spring (2) again, therefore, inner cover (10) at this moment does not move. When the jacket (1) drives the central shaft (7) and the support block (6) to continue to move up along the central shaft slideway (16), the four-corner steering device (8) touches the barb on the right spring piece (3) Afterwards, support block (6) just makes 90 degree rotations. Because the two spring sheets (3) on the left and right are clamping the four-corner steering device (8), the four-corner steering device (8) and the support block (6) will not easily change the direction position when moving up and down. After the needle roller (15) at the maximum dia...

Abstract

The present invention relates to a tube ejector on spinning frame with integral doffing device. It mainly includes the following several portions: mobile supporting block, left and right two supporting arms, left and right two supporting legs, tetragonal direction-regulating device, spring sheet and clamp spring. Said invention also provides its working principle and concrete operation method.

Description

Technical field: [0001] The invention relates to a spinning frame with a collective doffing device, in particular to a tube puller equipped with a collective doffing device on the spinning frame. Background technique: [0002] At present, there are two types of extruders. One is to clamp the middle part of the bobbin with an airbag for extubation and doffing. There are also different degrees of damage; there is also a gripper that clamps the top of the bobbin for pulling and doffing. This kind of gripper clamps and releases the top of the bobbin for a long time, so that the bobbin The top of the yarn is unfavorable, and the position of the clamped bobbin cannot be wound, which reduces the spinning time and increases the number of doffing times. Invention content: [0003] The object of the present invention is to address the above-mentioned deficiencies in the prior art, and propose a tube puller that can be supported on the inner wall of the bobbin. [0004] Two semicir...
