Embodiment 1

[0032] Such as figure 1 with figure 2 As shown, a buffer device for preventing yarn breakage of the present invention includes a power device 301, a fixing member 302 and an elastic member 303, the output shaft of the power device 301 is fixedly connected to the fixing member 302, and the power device 301 drives and fixes The part 302 swings, and one end of the fixed part 302 is fixedly connected with the elastic part 303 .

[0033] When installing the buffer device with the above structure, the fixed part 302 in the buffer device is movably connected to the moving frame 2 of the doffing machine through the movable part 9 . The movable part 9 can be a bearing, a hinge, a spring hinge, a torsion spring, a sliding brace or a gas spring. The fixed part 302 can rotate around the movable part. The whole buffer device moves with the moving frame 2 .

[0034] In the buffer device with the above structure, the power device 301 is used to periodically drive the fixing part 302 and...

Embodiment 2

[0040] Such as image 3 with Figure 4 As shown, a doffer, the doffer includes a doffer body 1, a moving frame 2 and a buffer device 3, the moving frame 2 is slidably connected to the doffer body 1, and the moving frame 2 is provided with a pipe discharge channel 201. The buffer device 3 is connected on the mobile frame 2 . As a preferred solution, the buffer device 3 includes a power device 301 , a fixing part 302 and an elastic part 303 . The power device 301 is connected to the moving frame 2 , one end of the fixing member 302 is fixedly connected to the elastic member 303 , and the other end of the fixing member 302 is movably connected to the moving frame 2 . The output shaft of the power device 301 is fixedly connected with the fixing part 302, and the power device 301 drives the fixing part 302 to swing. Figure 4 In , the direction of the arrow is the forward direction of the doffer. Figure 5 The forward direction of the middle doffing machine and Figure 4 same...

Embodiment 3

[0051] A working method of a doffer, comprising the following steps:

[0052] Step 10): start the doffing machine, use the bobbin grabber of the doffer to pull the full yarn bobbin from the spindle bar of the spinning frame, then discharge the empty bobbin 5 from the pipe discharge channel 201 of the moving frame, and insert it into the spindle On the rod 6; during the falling process of the empty bobbin 5, utilize the buffer device 3 connected to the moving frame 2 to buffer the empty bobbin 5, reduce the falling speed of the empty bobbin 5, and the empty bobbin 5 falls to the bottom of the spindle bar; until The doffing frame moves to the end of spinning frame 7 to complete the work of catching full bobbins and inserting empty bobbins.

[0053] In the above method, the buffer device 3 adopted comprises a power unit 301, a fixed part 302 and an elastic part 303, the power unit 301 is connected on the moving frame 2, one end of the fixed part 302 is fixedly connected with the ...

Abstract

The invention discloses a damping device for preventing yarn breakage. The damping device comprises a power device, a fixing piece and en elastic piece, wherein an output shaft of the power device is fixedly connected with the fixing piece, the power device drives the fixing piece to swing, and one end of the fixing piece is fixedly connected with the elastic piece. According to the damping device for preventing the yarn breakage, a yarn left on a spindle blade can be effectively prevented from being inserted to be broken by using the damping device when an empty bobbin is inserted, and therefore the yarn end remaining rate is improved; meanwhile, the invention further provides a doffing machine, the damping machine is arranged on the doffing machine, the empty bobbins discharged from a tube discharging cylinder of the doffing machine is not prone to break the yarns, the yarn end remaining rate is improved, and the workload of yarn connecting workers is reduced. The invention further provides a working method for the doffing machine, the yarn end remaining rate can be improved, balloon separators are not needed to be overturned, and therefore the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of ring spinning equipment, and in particular relates to a buffer device for preventing yarn breakage, a doffer and a working method thereof. Background technique [0002] The traditional spinning work involves a job of inserting the unspun empty bobbin on the spindle bar of the spinning frame. A few turns of yarn are left on the spindle rod so that the spindle rod rotates to wind the yarn around the empty bobbin during the next round of work, so that the empty bobbin becomes a full bobbin. Currently, in the textile field, artificial cannulas exist. Manual intubation refers to inserting the empty bobbin into the spindle bar manually. Due to the different control of manual strength, the force of inserting the empty bobbin is often too large, so that the empty bobbin will be interrupted by the yarn remaining on the spindle bar. This requires manual rewinding of the yarn on the spindle. The head retention r...
