Description

Technical Field

[0001] The present application relates to the technical field of textile manufacturing, and in particular to a forming device for spun yarn. Background Art

[0002] The formation of staple yarn is mainly to twist the fiber strands into a continuous yarn with a certain twist and strength. During the spinning process, the fibers are stretched, twisted and properly shaped to form a fine yarn with a certain thickness and twist. This process is commonly known as the formation of staple yarn.

[0003] Existing staple yarn forming devices usually include a feeding system, a combing system, a drafting system, a twisting system and a winding system. The feeding system is mainly responsible for evenly feeding the raw staple fibers into the combing system to ensure uniform fiber supply; the combing system is mainly responsible for sorting and arranging the fed staple fibers, removing impurities, and preparing for subsequent drafting and twisting; the drafting system mainly uses a series of roller drafting to further lengthen and refine the combed fibers, so as to achieve the fineness and uniformity required for spinning; the drafted fibers are passed through a twisting device, such as a ring spindle or a rotor, to be given the necessary twist, so that yarn with certain strength and elasticity can be formed; the twisted yarn will be wound on a bobbin in the winding system for easy storage and transportation.

[0004] In the winding system of the forming device, the bobbin is provided with a driving source for driving the bobbin to rotate around its own central axis to wind up the twisted yarn so that the yarn is wound around the outer peripheral wall of the bobbin. However, in actual work, when the bobbin winds up the yarn, the yarn often gets entangled with each other on the outer peripheral wall of the bobbin, which makes it difficult to unwind the yarn on the subsequent bobbin when it is needed, so further improvement is needed.

[0015] By adopting the above-mentioned technical scheme, through the arrangement of the eccentric rod, the switching sleeve, the pushing rod and the switching member, when the rotating shaft rotates to drive the cutter to move, the rotating shaft drives the switching sleeve to rotate a certain angle through the eccentric rod and the pushing rod. Under the action of the switching member, the switching sleeve and the switching disk rotate synchronously, thereby driving the switching disk to rotate a certain angle, so as to transfer the bobbin full of yarn in the winding station out of the winding station, and at the same time transfer the bobbin of the next rotating roller into the winding station.

In this process, the reciprocating screw rod and the rotating rod rotate synchronously through the linkage part. The reciprocating screw rod is passed through the guide block and is threadedly connected to the guide block, so that the guide block can be driven to move back and forth along the guide slide to guide the yarn, so that the yarn is wound around the outer peripheral wall of the bobbin as evenly as possible, thereby improving the operational convenience of the overall structure.

[0047] The implementation principle of Example 1 of the present application is as follows: the yarn twisted by the twisting system passes through the through hole 321 of the guide block 32, and then is wound on the bobbin 22 in the winding station 71, and the rotating roller 21 is driven to rotate by the rotating motor 42, so that the bobbin 22 winds up the yarn; after the bobbin 22 winds up a certain number of turns of yarn, the rotating shaft 12 is driven to rotate, and the lifting seat 13 moves downward under the action of the rotating disk 61, the eccentric column 62 and the connecting rod 63, so that the cutter 131 cuts the yarn; in this process, the rotating shaft 12 drives the eccentric rod 81 to revolve around the central axis of the rotating shaft 12, thereby pushing the pushing rod 83, and under the action of the switching sleeve 82, the switching ring 84 and the pushing block 85, the switching disk 7 can rotate synchronously, thereby rotating the rotating roller 21 out of the winding station 71 and transferring the next rotating roller 21 into the winding station 71, thereby improving the operational convenience of the overall structure.

[0048] As the rotating shaft 12 continues to rotate, the rotating disk 61 can pull the lifting seat 13 through the connecting rod 63 to lift the cutter 131 off the guide seat 31. During this process, the switching sleeve 82 is reversed under the pull of the pushing rod 83, so that the pushing block 85 is separated from the pushing groove 841 along the guide surface 842 of the pushing groove 841 and transferred to the next pushing groove 841 of the switching ring 84, so that when it is necessary to continue cutting the yarn, the pushing block 85 can push the switching ring 84 to rotate again, further improving the operational convenience of the overall structure.

[0049] Embodiment 2: The embodiment of the present application discloses a forming device for spun yarn.

[0050] Reference Figure 8 The difference between the spun yarn forming device disclosed in the embodiment of the present application and the embodiment 1 is that: In this embodiment, the guide seat 31 is provided with an abutment assembly 9. When the cutter 131 moves downward to cut the yarn, the abutment assembly 9 is used to abut against the free end of the yarn so that the free end of the yarn remains inserted into the guide block 32.

[0051] Reference Figure 8 The abutment assembly 9 includes an abutment strip 91, a return spring 92, a clamping strip 92 and a clamping joint 94. The abutment strip 91 is slidably installed on the guide seat 31 and can slide in the height direction. The abutment strip 91 is located on the side of the guide block 32 close to the rotating roller 21; one end of the return spring 92 is fixedly connected to the abutment strip 91, and the other end is fixedly connected to the guide seat 31. The return spring 92 normally moves the abutment strip 91 to above the penetration hole 321 of the guide block 32 (that is, when the yarn is penetrated through the penetration hole 321, the abutment strip 91 is located above the yarn); when the cutter 131 moves down to cut the yarn, the lifting seat 13 pushes the abutment strip 91, forcing the abutment strip 91 to move down so that the abutment strip 91 is pressed against the yarn.

[0052] The snap-in strip 92 is elastically arranged and vertically arranged. The upper end of the snap-in strip 92 is fixedly installed on one end of the abutting strip 91, and the lower end of the snap-in strip 92 is fixedly installed on the snap-in joint 94. The snap-in joint 94 has a guide surface 941. The side wall of the guide seat 31 is fixedly installed with a snap-in piece 312 for snapping the snap-in joint 94. The snap-in piece 312 is located below the abutting strip 91. When the abutting strip 91 moves downward and presses against the yarn, the snap-in joint 94 forces the snap-in strip 92 to deform through the guide surface 941, so that the snap-in joint 94 is snapped into the bottom wall of the snap-in piece 312, thereby making the snap-in joint 94 and the snap-in piece 312 snap into each other.

[0053] The implementation principle of Example 2 of the present application is as follows: after the bobbin 22 winds up a certain number of turns of yarn, the cutter 131 is driven to move down to cut the yarn. When the cutter 131 moves down, the lifting seat 13 pushes the abutment bar 91 down, thereby pressing the yarn tightly. At this time, the clamping joint 94 moves down and engages with the clamping piece 312, so that the abutment bar 91 remains pressed against the yarn. The setting of the abutment bar 91 enables the free end of the yarn after cutting to remain inserted into the insertion hole 321 of the guide block 32 (the free end of this yarn is the free end of the yarn led out by the twisting system), reducing the possibility that the yarn after cutting will fall under the action of gravity, which will lead to the possibility that the operator will need to pull the yarn again to make the yarn pass through the insertion hole 321.

[0054] When the yarn needs to be pulled to a new bobbin 22, the free end of the yarn is pulled and the clamping joint 94 is bendable to disengage the clamping joint 94 from the clamping piece 312. The abutment strip 91 moves upward under the action of the return spring 92 to release the tightening effect on the yarn. The free end of the yarn can then be pulled to dock with the new bobbin 22, thereby improving the working efficiency of the overall structure.

[0055] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
