AI Technical Summary
Existing yarn rolls are prone to knotting during the unwinding process due to changes in traction force, and traditional tensioning wheels are not effective in controlling this.
The cylinder-driven pressing device ensures that the pressing pads are tightly attached to the surface of the yarn roll through the cooperation of upper and lower springs. The linear displacement of the pressing pads is achieved by using sliders and guide rails to prevent the yarn roll from rotating freely and to achieve stable yarn feeding.
This effectively prevents the yarn roll from knotting due to inertia during the unwinding process, ensuring stable yarn output and improving the reliability and efficiency of unwinding.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile machinery technology, and in particular to a yarn winding and unwinding device. Background Technology
[0002] Yarn is a type of textile product made from various textile fibers processed into a certain fineness. It is used for weaving, rope making, thread making, knitting, and embroidery, and is divided into short fiber yarn and continuous filament yarn. In the yarn processing process, the yarn needs to be tested, dyed, and woven. Regardless of the processing method, the yarn spool needs to be unwound.
[0003] Currently, during the unwinding process of yarn spools, the yarn spool is mostly rotated by the traction force of the unwinding yarn, and the unwinding is controlled by the weight of the yarn spool itself. If the traction force changes, the yarn unwinding from the yarn spool will knot. Traditional unwinding uses a tensioning wheel to control the knotting of the yarn, which is ineffective. Therefore, this application discloses a textile yarn spool unwinding device. Utility Model Content
[0004] The purpose of this invention is to address existing problems by providing a yarn winding and unwinding device.
[0005] This utility model is achieved through the following technical solution:
[0006] A textile yarn winding and unwinding device includes a platform, on which seat plates are installed at intervals. A shaft is vertically connected to the seat plates. A pressure plate is provided on one side of the shaft. Ear seats are provided at intervals on the outer curved surface of the pressure plate. A booster mechanism is provided between the upper ear seat and the vertical plate. A thrust mechanism is provided between the lower ear seat and the vertical plate. A cylinder is connected to the outside of the vertical plate. The telescopic rod of the cylinder is connected to the thrust mechanism.
[0007] As a further improvement to the above solution, the booster mechanism includes an inner rod, one end of which is hinged to an ear seat, and the other end of which is inserted into an outer tube. The outer tube is hinged to a vertical plate, and a spring is fitted on the inner rod. One end of the upper spring abuts against a collar, the collar is fitted onto the inner rod, and the other end of the upper spring abuts against the end of the outer tube.
[0008] The upper part of the pressure plate is pushed by the force of the upper spring, so that the upper part of the pressure plate presses against the outer surface of the upper part of the yarn roll, which facilitates the bonding of the outer surface of cylindrical and conical yarns.
[0009] As a further improvement to the above solution, the thrust mechanism includes a push rod, one end of which is connected to a vertical block, the vertical block is hinged to an ear seat, the other end of which is inserted into the telescopic rod of the cylinder, and a lower spring is sleeved on the push rod.
[0010] The lower spring causes the pressure plate to approach or move away from the yarn roll. At the same time, the lower spring is compressed and shortened. The force of the lower spring pushes the pressure plate to always adhere to the surface of the yarn roll.
[0011] As a further improvement to the above solution, the lower end of the standing block is connected to the slider, the slider is matched and set on the guide rail, and the guide rail is installed on the platform.
[0012] By sliding the slider on the guide rail, the linear displacement of the pressing tile is ensured, so that the inner curved surface of the pressing tile completely presses against the outer curved surface of the yarn roll.
[0013] As a further improvement to the above solution, the two sides of the pressing tile are provided with outward flanges to prevent the edges of the pressing tile from scratching the surface of the yarn roll.
[0014] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. By extending and retracting the telescopic rod of the cylinder, and using the lower spring to drive the pressure plate to approach or move away from the yarn roll, the lower spring is compressed and its force pushes the pressure plate to always be in contact with the surface of the yarn roll. This ensures that the yarn on the yarn roll will only be released under the traction force during the unwinding process, avoiding the yarn roll from rotating freely and unwinding, and preventing the yarn roll from knotting due to free unwinding caused by traction inertia.

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] like Figure 1-3 As shown, a textile yarn winding and unwinding device includes a platform 1, on which seat plates 2 are installed at intervals. A shaft 3 is vertically connected to the seat plate 2. A pressure plate 4 is provided on one side of the shaft 3. Ear seats 42 are provided at intervals on the outer curved surface of the pressure plate 4. A booster mechanism 6 is provided between the upper ear seat 42 and the upright plate 7, and a thrust mechanism 5 is provided between the lower ear seat 42 and the upright plate 7. A cylinder 8 is connected to the outside of the upright plate 7, and the telescopic rod of the cylinder 8 is connected to the thrust mechanism 5.
[0020] As a further improvement to the above solution, the booster mechanism 6 includes an inner rod 61, one end of which is hinged to the ear seat 42, and the other end of which is inserted into the outer tube 64. The outer tube 64 is hinged to the upright plate 7. A spring 62 is fitted on the inner rod 61, one end of which abuts against a collar 63, which is fitted onto the inner rod 61, and the other end of which abuts against the end of the outer tube 64.
[0021] The upper part of the pressure plate 4 is pushed by the force of the upper spring 62, so that the upper part of the pressure plate 4 presses against the outer surface of the upper part of the yarn roll, which facilitates the bonding of the outer surface of the cylindrical and conical yarns.
[0022] As a further improvement to the above scheme, the thrust mechanism 5 includes a push rod 54, one end of which is connected to the upright block 51, the upright block 51 is hinged to the ear seat 42, the other end of which is inserted into the telescopic rod of the cylinder 8, and a lower spring 55 is sleeved on the push rod 54.
[0023] The lower spring 55 drives the pressure plate 4 to approach or move away from the yarn roll. At the same time, the lower spring 55 is compressed and shortened. The force of the lower spring 55 pushes the pressure plate 4 to always adhere to the surface of the yarn roll.
[0024] As a further improvement to the above solution, the lower end of the standing block 51 is connected to the slider 52, the slider 52 is matched and set on the guide rail 53, and the guide rail 53 is installed on the platform 1.
[0025] By sliding the slider 52 on the guide rail 53, the linear displacement of the pressure tile 4 is ensured, so that the inner curved surface of the pressure tile 4 completely presses against the outer curved surface of the yarn roll.
[0026] As a further improvement to the above solution, the two sides of the pressing tile 4 are provided with outward flanges 41 to prevent the edges of the pressing tile 4 from scratching the surface of the yarn roll.
[0027] The working principle of a textile yarn unwinding device is as follows: the extension and retraction of the telescopic rod of the cylinder 8, and the use of the lower spring 55 to drive the pressure plate 4 to approach or move away from the yarn roll. At the same time, the lower spring 55 is compressed and shortened. The force of the lower spring 55 pushes the pressure plate 4 to always be in contact with the surface of the yarn roll. This ensures that the yarn on the yarn roll is only unwound under the traction force during the unwinding process, avoiding the yarn roll from rotating freely and unwinding, and preventing the yarn roll from knotting due to free unwinding caused by traction inertia.
[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
