Embodiment 1

[0062] see figure 1 — Figure 8 , an integrated device for lowering yarn and changing tubes, including a winding bobbin clamp 2, a bobbin clip connecting plate 3, a yarn lowering unit 4 and an empty tube storage unit 5, the winding bobbin clip 2 includes a clamping top beam 21, a movable side The arm 22 is connected with the fixed side arm 23, the rear end of the top clip beam 21 is connected with the front end of the bobbin clip connecting plate 3, and the two ends of the top clip beam 21 are respectively connected with the movable side arm 22 and the top end of the fixed side arm 23. , the top end of the movable side arm 22 is hinged with the clip top beam 21, and the bottom ends of the movable side arm 22 and the fixed side arm 23 are respectively provided with a movable insert plate 25 and a fixed insert plate 26. The movable side arm 22 is near the movable insert plate. 25 is connected with the inner end of the oblique handle 24, and the outer end of the oblique handle 2...

Embodiment 2

[0065] The basic content is the same as that of Example 1, except that:

[0066] The outer gripper 41 includes an upper gripper 411 , a middle gripper 412 and a lower gripper 413 . The inner end of the upper gripper 411 is vertically connected to the top of the middle gripper 412 , and the inner end of the lower gripper 413 is connected to the middle gripper 412 . The bottom ends of the grabbing plates 412 are connected vertically, the outer ends of the upper grabbing plates 411 and the lower grabbing plates 413 both extend in the direction away from the lower yarn base plate 42, and the central axis connecting line between the upper grabbing plates 411 and the lower grabbing plates 413 is at The projection on the middle catch plate 412 is an oblique line. The lower yarn base 42 is a stepped structure, including a vertical first plate 421, a second flat plate 422, a vertical third plate 423 and a flat fourth plate 424. The other end of the outer gripper 41 is in contact with t...

Embodiment 3

[0068] The basic content is the same as that of Example 1, except that:

[0069] The inner concave push plate 44 includes an inclined upward extension plate 441, a vertical middle straight plate 442, an inclined downward extension plate 443 and an upper hook horizontal plate 444. The top of the middle straight plate 442 is connected with the low end of the inclined upward extension plate 441 , the bottom of the vertical middle straight plate 442 is connected with the high end of the inclined downward extension plate 443 , and the low end of the inclined downward extension plate 443 is connected with the bottom of the upper hook horizontal plate 444 . When connected, the top of the upper hook horizontal plate 444 is upturned and extended; the inclined upper extension plate 441 , the vertical middle straight plate 442 , the inclined downward extension plate 443 , and the upper hook horizontal plate 444 are clamped together to form the same push plate clamping groove 445 .

Abstract

An integrated device for changing tubes for lower yarn, comprising a lower yarn unit, an empty tube storage unit, a winding bobbin clamp and a bobbin clamp connecting plate, the winding bobbin clamp includes a clamping top beam, a movable side arm and a fixed side arm, the clamp The rear end of the top beam is connected to the front end of the bobbin clamp connecting plate. The yarn lowering unit includes an outer gripper, a yarn lowering base plate, a driver and an inner concave push plate. The empty tube storage unit includes a tube release part and a guide tube The tube release part is connected with the bobbin clamp connecting plate, at least one empty tube is arranged inside the tube release part, the front end of the tube release part is connected with the high end of the guide tube part, and the bottom end of the guide tube part faces the lower yarn The direction of the clamp groove of the push plate in the unit extends, and there is a yarn output gap between the bottom end of the guide pipe and the clamp groove of the push plate. This design not only simplifies the operation steps, realizes automatic yarn lowering and tube changing, but also runs smoothly and has high production efficiency, which is beneficial to reduce production costs.

Description

technical field [0001] The invention relates to a technology for replacing a finished yarn roll in a direct twisting machine, belonging to the field of textile machinery, in particular to an integrated device for changing lower yarns. Background technique [0002] In the direct twisting machine or the double machine, when the empty winding bobbin (ie the empty tube) is wound on the machine, it is the finished yarn roll. At this time, the finished yarn roll needs to be taken off and replaced with an empty tube. , The operations of removing the finished yarn roll and replacing the empty tube are mostly manual operations. When operating, it is necessary to manually lift the bobbin clamp together with the finished yarn roll, and then cooperate with both hands to take off the finished yarn roll, and then put the finished yarn roll. Place it on the doffing car, and then replace the empty tube on the bobbin clamp with both hands, which is not only cumbersome, but also labor-intensi...
