The sliver is stretched and twisted on the roving frame to make roving, the combing machine combs the fiber to make combed sliver, the gill combing machine combines the slivers, and the pin row stretching improves the sliver structure. The roving is further twisted and spun into spun yarn on the ring spinning frame. The spinning frame is the main machine for spinning. The output and quality of spun yarn are a comprehensive reflection of the quality of each process of the spinning process.
[0003] The patent document with publication number "CN220538026U" discloses a yarn doffing device for a spinning frame for producing polyester yarn, which is characterized in that it includes: a yarn doffing box, a first mounting groove is symmetrically opened at the bottom of the yarn doffing box, and a transmission motor and the like are fixedly connected to the inside of the first mounting groove.
[0004] Although the prior art solves the problem of the yarn bobbin tilting during the upward movement, due to the small diameter of the yarn bobbin, the yarn bobbin needs to be carefully aligned before it can be clamped and moved. At the same time, during the movement of the yarn bobbin, the collecting device is not in a fixed state and is prone to deviation, which is not conducive to normal use. Utility Model Content
[0005] The purpose of the utility model is to solve the following shortcomings in the prior art: due to the small diameter of the yarn tube, before the yarn tube is clamped and moved, it is necessary to carefully align the yarn tube before clamping it; at the same time, during the movement of the yarn tube, the collecting device is not in a fixed state and is prone to deviation, which is not conducive to normal use. A yarn doffing device for a spinning frame for polyester yarn production is proposed.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A doffing device for a spinning frame for producing polyester yarn, comprising a collecting chamber and a mounting plate, wherein the mounting plate is arranged in a right-angle trapezoidal shape and is fixedly connected to the collecting chamber;
[0008] The mounting plate is provided with a plurality of slide grooves, and an extraction component is installed on the mounting plate, and the extraction component includes a slider, a clamping plate, a second spring, and a cross plate. The plurality of sliders are respectively slidably connected in the slide grooves, and the plurality of clamping plates are respectively divided into four groups, and each group of the clamping plates has two clamping plates, and the plurality of groups of the clamping plates are respectively slidably connected to the sliders, and two of the second springs are respectively fixedly connected between the clamping plates and the sliders, and the cross plate is fixedly connected to the plurality of sliders, and the clamping plates are arranged in a right-angle trapezoidal shape, and tooth patterns are provided on the inner side walls.
[0009] Preferably, the extraction component further comprises a sleeve and a push rod, wherein the sleeve is fixedly connected to the mounting plate, the lower end of the push rod is slidably connected in the sleeve, and the upper end of the push rod is fixedly connected to the cross plate.
[0010] Preferably, a fixing block is fixedly connected to the collecting chamber, and a sliding rod is slidably connected to the fixing block.
[0011] Preferably, an airbag is fixedly connected to the outer side wall of the collecting chamber, an upper end of the airbag is fixedly connected to the sliding rod, and a connecting tube is fixedly connected between the airbag and the sleeve.
[0012] Preferably, the lower end of the slide rod is fixedly connected to a first spring, and the lower end of the first spring is fixedly connected to a suction cup.
[0013] Preferably, universal wheels are respectively installed at the four corners of the collection chamber.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] 1. Even if the two clamps are slightly offset from the yarn tube, as long as they are on both sides of the yarn tube, the clamps can still clamp the yarn tube under the extrusion force of the second spring during the movement of the installation cavity. Since the inner wall of the clamp is provided with teeth, the teeth have an anti-slip effect on the yarn tube, which can achieve better clamping.
[0016] 2. As the slide bar continues to move downward, the first spring is pressurized and the airbag is compressed at the same time. The gas in the airbag enters the sleeve through the connecting pipe. As the gas in the sleeve increases, the push rod is pushed upward. When the cross plate, slider and clamping plate move upward with the push rod, the yarn tube can be driven upward, which is convenient for the staff to take it out and put it in the collection chamber.
[0017] 3. As the slide bar moves downward, the suction cup contacts the ground. Since the suction cup has adsorption properties to the ground, the friction with the ground can be increased, thereby avoiding the movement of the collection chamber when the yarn bobbin is collected.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.
[0023] Reference Figure 1-Figure 2 A doffing device for a spinning frame for producing polyester yarn comprises a collecting chamber 1 and a mounting plate 2, wherein the mounting plate 2 is arranged in a right-angle trapezoidal shape and is fixedly connected to the collecting chamber 1, and universal wheels 4 are respectively installed at the four corners of the collecting chamber 1;
[0024] The mounting plate 2 is provided with a plurality of slide grooves, which are used for the upward sliding of the slider 13. An extraction component is installed on the mounting plate 2, which includes a slider 13, a clamping plate 12, a second spring 15, and a cross plate 14. The plurality of sliders 13 are respectively slidably connected in the slide grooves, and the plurality of clamping plates 12 are respectively in four groups, each group of clamping plates 12 has two clamping plates, and the plurality of groups of clamping plates 12 are respectively slidably connected to the slider 13. The two second springs 15 are respectively fixedly connected between the clamping plates 12 and the slider 13. The cross plate 14 is fixedly connected to the plurality of sliders 13. The clamping plates 12 are arranged in a right-angle trapezoidal shape, and the inner There are teeth on the side wall. When the yarn bobbin is between the two clamping plates 12, since one end of the two clamping plates 12 is larger and the other end is gradually smaller, the elastic force of the second spring 15 pushes the clamping plate 12 to clamp the yarn bobbin. Since the elastic force of the second spring 15 is relatively small, it can only prevent the yarn bobbin from falling, but can easily pull the yarn bobbin out from the two clamping plate 12 brackets. The extraction component also includes a sleeve 9 and a push rod 11. The sleeve 9 is fixedly connected to the mounting plate 2. The lower end of the push rod 11 is slidably connected in the sleeve 9, and the upper end of the push rod 11 is fixedly connected to the cross plate 14.
[0025] A fixed block 7 is fixedly connected to the collecting chamber 1, a slide rod 3 is slidably connected to the fixed block 7, an airbag 10 is fixedly connected to the outer wall of the collecting chamber 1, an upper end of the airbag 10 is fixedly connected to the slide rod 3, and a connecting pipe 8 is fixedly connected between the airbag 10 and the sleeve 9.
[0026] In the utility model, when in use, the collecting chamber 1 is first pushed so that the two clamping plates 12 are located on both sides of the yarn tube and on the lower side of the yarn. Since the inner walls of the clamping plates 12 are arranged as inclined surfaces and slide on the slider 13, even if the two clamping plates 12 are slightly offset from the yarn tube, as long as they are located on both sides of the yarn tube, during the movement of the collecting chamber 1, the clamping plates 12 can still clamp the yarn tube under the squeezing force of the second spring 15. Since the inner walls of the clamping plates 12 are provided with teeth, the teeth have an anti-slip effect on the yarn tube, and can achieve better clamping.
[0027] After the clamping plate 12 clamps the yarn tube, the staff pushes the slide bar 3 to move downward. As the slide bar 3 moves downward, the suction cup 5 contacts the ground, and as the slide bar 3 continues to move downward, the first spring 6 is pressurized, and the airbag 10 is compressed at the same time. The gas in the airbag 10 enters the sleeve 9 through the connecting pipe 8. As the gas in the sleeve 9 increases, the push rod 11 is pushed upward. When the cross plate 14, the slider 13 and the clamping plate 12 move upward with the push rod 11, they can drive the yarn tube to move upward, which is convenient for the staff to take it out and put it in the collection chamber 1.
[0028] At the same time, when the suction cup 5 contacts the ground during the downward movement of the slide bar 3, the suction cup 5 has adsorption properties to the ground, which can increase the friction with the ground, thereby preventing the collection chamber 1 from moving when collecting the yarn bobbins.
[0029] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.
[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
