Description

Technical Field

[0001] The utility model relates to the technical field of beam-drawing machines, in particular to a multi-cylinder yarn automatic beam-drawing machine. Background Art

[0002] Beam-drawing is the first process in pre-weaving preparation. It mainly processes cheese yarns from the spinning department on a winding machine into cheese yarns that meet certain requirements, and supplies them to processes such as warping, pirn winding, knitting, weft supply of shuttleless looms, or bleaching and dyeing. A beam-drawing machine is a device that unwinds yarn from large spindles and winds it onto a yarn gathering cone or a yarn bobbin to form a yarn bobbin of a larger or smaller size, providing the most practical equipment for subsequent applications.

[0003] Currently, an existing multi-cylinder yarn automatic beam-drawing machine (such as patent number: CN214031186U) discloses a multi-cylinder yarn automatic beam-drawing machine, including a bracket. A motor is fixedly connected to the left side of the bracket. The output shaft of the motor penetrates the bracket and is fixedly connected to a rotating shaft. The surface of the rotating shaft is fixedly connected with three winding cylinders. Three supporting rollers are fixedly connected to the back of the bracket. Three unwinding cylinders are fixedly connected to the bottom of the bracket. Two supporting plates are fixedly connected to the back of the unwinding cylinder. A yarn guiding roller is rotatably connected between the two supporting plates. The beneficial effect of a multi-cylinder yarn automatic beam-drawing machine is that by setting the yarn guiding roller, when it is necessary to adjust the position of the yarn guiding roller, the yarn guiding roller is taken out forward, so that the yarn guiding roller is separated from the annular support, and then reinserted into the annular support at a suitable position, thereby guiding the yarn and improving the stability of guiding, effectively preventing the yarn from getting tangled.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems:

[0005] 1. The existing device uses a telescopic roller to control the tension of the yarn. However, the telescopic rollers of the existing device are set separately. When it is necessary to adjust the tension of the yarn, it is necessary to adjust multiple independent telescopic rollers, which is rather troublesome. Moreover, when adjusting the telescopic rollers, it is necessary to make the extension distances of the telescopic rollers equal, otherwise the tensions between different telescopic rollers and the yarn will be different, which may cause the yarn wound on the winding cylinder to get tangled.

[0006] 2. The supporting rollers of the existing device are not provided with a convenient and fast adjustment mechanism, making it difficult to adjust the extension distance when the supporting position of the supporting rollers needs to be adjusted. Therefore, the supporting rollers of the existing device have the problem of being difficult to adjust. Summary of the Utility Model

[0007] (1) Technical Problems to be Solved

[0008] In view of the deficiencies of the prior art, the utility model provides an automatic multi-cylinder yarn rewinder, which solves the technical problems that the telescopic rollers of the existing device are costly and may cause wire entanglement, and the support rollers are not easy to adjust.

[0009] (II) Technical solution

[0010] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0011] An automatic multi-cylinder yarn rewinder includes a support plate. Two side plates are fixedly connected to the support plate. A control panel is fixedly connected to the side wall of the side plate. A driving mechanism is arranged at the top of the side plate. The driving mechanism includes a motor, a rotating rod and a winding cylinder. The motor is electrically connected to the control panel. A bottom plate is fixedly connected to the bottom of the support plate. A wire guiding mechanism and a unwinding cylinder are arranged on the top surface of the side plate. The wire guiding mechanism includes a support plate, an annular support and a yarn guiding roller. The yarn guiding roller is rotatably connected to the support plate. A tension adjusting mechanism and a support mechanism are fixedly arranged in the middle section of the side plate. The tension adjusting mechanism is located above the support mechanism. First sliding grooves are opened on the opposite surfaces of the two side plates. The tension adjusting mechanism includes an electric telescopic rod. The electric telescopic rod is electrically connected to the control panel. The support mechanism includes a C-shaped bracket.

[0012] Preferably: The electric telescopic rod is fixedly installed in the middle section of the support plate. A connecting frame is fixedly connected to the driving end of the electric telescopic rod. The connecting frame is C-shaped. A first fixing rod is fixedly connected to the side of the connecting frame away from the electric telescopic rod. A tension pulley is rotatably connected to the first fixing rod. The number of tension pulleys is equal to the number of winding cylinders. First sliders are fixedly connected to both ends of the first fixing rod.

[0013] Preferably: The two first sliders are respectively slidably connected in the two first sliding grooves.

[0014] Preferably: The C-shaped bracket is C-shaped. Second sliding grooves are opened at both C-shaped arms of the C-shaped bracket. Plugging holes are also opened at both C-shaped arms of the C-shaped bracket. The total number of plugging holes is fourteen. Plug pins are inserted into the plugging holes. The total number of plug pins is two. A pull ring is fixedly connected to the top of the plug pin.

[0015] Preferably: The support mechanism further includes a second fixing rod. A support wheel is rotatably connected to the second fixing rod. The number of support wheels is equal to the number of winding cylinders. The support wheel includes a runner and a tension sensor. The tension sensor is arranged in the middle section of the runner. The tension sensor is electrically connected to the control panel. Second sliders are fixedly connected to both ends of the support wheel.

[0016] Preferably: The two second sliders are respectively slidably connected in the two second sliding grooves. Through holes are opened in the two second sliders. Plug pins are inserted into the through holes.

[0017] (III) Beneficial effects

[0018] 1. The end of the yarn exported from the unwinding cylinder sequentially passes through the yarn guide roller, support wheel, and tension wheel of the wire guiding mechanism and is finally wound around the winding cylinder of the driving mechanism. The driving mechanism is started to operate as a whole through the control panel. The winding cylinder winds the yarn into a formed shape. The tension sensor included in the support wheel detects the tension of the yarn. After the tension sensor detects the tension between the yarn and the support wheel, the control panel controls the telescopic movement of the electric telescopic rod, thereby driving the connecting frame and the first fixing rod to move. The first fixing rod slides in the first chute through the first slider, and finally drives the tension wheel to move, realizing the control of the yarn tension, making the yarn winding uniform and stable. Only one electric telescopic rod is provided to drive the displacement of the tension wheel, which not only saves costs but also has the advantage of being convenient for adjustment through the control panel. Moreover, the displacement of each tension wheel driven by only one electric telescopic rod makes the positions of each tension wheel the same, solving the problem that the telescopic roller of the existing device has a high cost and may cause wire entanglement.

[0019] 2. The telescopic distance of the electric telescopic rod is limited. When the electric telescopic rod is damaged or the yarn tension is not within the adjustment range of the electric telescopic rod, two pins can be pulled out, and the second fixing rod and the support wheel are driven by the second slider to be located in the second chute. After adjusting the position of the second slider, the pins can be reinserted into the insertion holes and through holes to fix the second slider, enabling the support wheel to have an adjustment effect, solving the problem that the support roller of the existing device is not easy to adjust. The adjustable support wheel can make the tension adjustment range wider.

[0020] 3. By providing the first chute and the first slider, the displacement of the first fixing rod is more stable, so that the position of the tension wheel adjusted by the electric telescopic rod 401 is more accurate. BRIEF DESCRIPTION OF THE DRAWINGS

The general idea is as follows:

[0029] In view of the problems existing in the prior art, the present utility model provides an automatic multi-cylinder yarn rewinder, which includes a support plate 1. Two side plates 101 are fixedly connected to the support plate 1. A control panel 2 is fixedly connected to the side wall of the side plate 101. A driving mechanism 3 is arranged on the top of the side plate 101. The driving mechanism 3 includes a motor, a rotating rod and a winding cylinder. The motor is electrically connected to the control panel 2. A bottom plate 103 is fixedly connected to the bottom of the support plate 1. A wire guiding mechanism 6 and an unwinding cylinder 7 are arranged on the top surface of the side plate 101. The wire guiding mechanism 6 includes a support plate, an annular support and a yarn guiding roller. The yarn guiding roller is rotatably connected to the support plate. A tension adjusting mechanism 4 and a supporting mechanism 5 are fixedly arranged in the middle section of the side plate 101. The tension adjusting mechanism 4 is located above the supporting mechanism 5. A first chute 102 is opened on each of the opposite surfaces of the two side plates 101. The tension adjusting mechanism 4 includes an electric telescopic rod 401. The electric telescopic rod 401 is electrically connected to the control panel 2. The supporting mechanism 5 includes a C-shaped bracket 501.

[0030] The electric telescopic rod 401 is fixedly installed in the middle section of the support plate 1. The driving end of the electric telescopic rod 401 is fixedly connected to a connecting frame 402. The connecting frame 402 is C-shaped. A first fixing rod 403 is fixedly connected to the side of the connecting frame 402 away from the electric telescopic rod 401. A tension pulley 404 is rotatably connected to the first fixing rod 403. The number of the tension pulleys 404 is equal to the number of the winding cylinders. First sliders 405 are fixedly connected to both ends of the first fixing rod 403.

[0031] Two first sliders 405 are respectively slidably connected within two first sliding grooves 102.

[0032] The C-shaped bracket 501 is C-shaped. Second sliding grooves 502 are provided at both C-shaped arms of the C-shaped bracket 501. Plugging holes 503 are also provided at both C-shaped arms of the C-shaped bracket 501. The total number of plugging holes 503 is fourteen. Plug pins 504 are plugged within the plugging holes 503. The total number of plug pins 504 is two. A pull ring is fixedly connected to the top of the plug pin 504.

[0033] The support mechanism 5 further includes a second fixed rod 507. A support wheel 508 is rotatably connected to the second fixed rod 507. The number of support wheels 508 is equal to the number of winding cylinders. The support wheel 508 includes a runner and a tension sensor. The tension sensor is arranged in the middle section of the runner. The tension sensor is electrically connected to the control panel 2. Second sliders 505 are fixedly connected to both ends of the support wheel 508.

[0034] Two second sliders 505 are respectively slidably connected within two second sliding grooves 502. Through holes 506 are provided on both second sliders 505. The plug pins 504 are plugged within the through holes 506.

[0035] Working principle:

[0036] First step, the end of the yarn led out from the unwinding cylinder 7 sequentially passes through the yarn guiding roller of the wire guiding mechanism 6, the support wheel 508 and the tensioning wheel 404 and is finally wound around the winding cylinder of the driving mechanism 3. The driving mechanism 3 is started to operate as a whole through the control panel 2. The winding cylinder winds the yarn into a formed shape. The tension sensor included in the support wheel 508 detects the tension of the yarn. After the tension sensor detects the tension between the yarn and the support wheel 508, the control panel 2 controls the telescopic movement of the electric telescopic rod 401, thereby driving the connecting frame 402 and the first fixed rod 403 to move. The first fixed rod 403 slides within the first sliding groove 102 through the first slider 405, and finally drives the tensioning wheel 404 to move, realizing the control of the tension of the yarn, making the yarn winding uniform and stable. Only one electric telescopic rod 401 is provided to drive the displacement of the tensioning wheel 404, which not only saves costs, but also has the advantage of being convenient for adjustment through the control of the control panel 2.

[0037] Second step, the telescopic distance of the electric telescopic rod 401 is limited. When the electric telescopic rod 401 is damaged or the yarn tension is not within the adjustment range of the electric telescopic rod 401, the two plug pins 504 can be pulled out, and the second fixed rod 507 and the support wheel 508 are driven to be located within the second sliding groove 502 through the second slider 505. After adjusting the position of the second slider 505, the plug pins 504 can be re-plugged into the plugging holes 503 and the through holes 506 to fix the second slider 505, enabling the support wheel 508 to have an adjustable effect.

[0038] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
