Description

Technical Field

[0001] The invention relates to a coated yarn production device, in particular to an antibacterial composite yarn production coating device. Background Art

[0002] Coated yarn is a composite yarn composed of a core yarn and an outer covering material. Its structure is: usually filament, staple fiber or untwisted sliver is used as the core yarn, and the outer layer is wrapped with another yarn or filament in a spiral winding manner. The outer covering material tightly covers the core yarn to form a yarn structure with good elasticity, strong wear resistance and not easy to deform. For example, spandex coated yarn has spandex as the core and the outer layer is wrapped with chemical fiber filament or staple fiber. Utilizing the special structure of the coated yarn, there is now an antibacterial composite yarn, whose core yarn has an antibacterial effect after being treated with an antibacterial liquid. Due to the outer layer wrapping, the antibacterial substance on the core yarn is not easy to lose, so the antibacterial effect is significantly prolonged.

[0003] Existing covered yarns are mainly produced through hollow spindle spinning devices. The core yarn and the outer covering material are combined in the high-speed rotating hollow spindle to form a spiral wrapping structure. During the covering process, the feeding speed of the core yarn and the feeding speed of the winding yarn must be kept constant, and the winding yarn (covering yarn) must maintain a certain tension, otherwise it will lead to uneven product performance. In order to achieve the above requirements, it is necessary to develop a covered yarn production equipment. Summary of the invention

[0004] The invention provides an antibacterial composite yarn production coating device, which solves the problem in the prior art that the feeding speed of the core yarn and the feeding speed of the winding yarn fluctuate to a certain extent.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: an antibacterial composite yarn production and coating equipment, including a first support seat, a second support seat, a rotating cage and a fixed toothed disc, the two support seats are fixedly arranged, and two coaxial threading holes are provided on the two support seats, and core yarns are coaxially passed through the threading holes, and the rotating cage is composed of a first annular sheet, a second annular sheet, a plurality of yarn guide modules, a first rotating sleeve and a second rotating sleeve, and the two rotating sleeves are respectively rotatably matched with the two support seats, and a transmission gear is coaxially provided on the second rotating sleeve, a first connecting rod is connected between the first annular sheet and the first rotating sleeve, and a first connecting rod is connected between the second annular sheet and the second A second connecting rod is connected between the rotating sleeves, the first annular plate is coaxially fixed with the second annular plate, the fixed toothed disk is fixed relative to the two support seats and is coaxially arranged with respect to the core yarn, the yarn leading module is arranged in a circular array between the two annular plates, including a bobbin shaft fixed on the two annular plates and a plurality of lead rollers fitted to each other, a first gear is coaxially fixed to one end of all the lead rollers, all the first gears are meshed with each other, a second gear is coaxially fixed to the other end of one of the lead rollers, the second gear is meshed with the fixed toothed disk, a coated yarn bobbin is rotatably provided on the bobbin shaft, and the coated yarn on the coated yarn bobbin is wound into the core yarn after being guided by the lead roller.

[0006] The present invention does not include a structure for pulling and stretching the core yarn, so the present invention needs to be combined with the existing core yarn pulling and stretching equipment. The specific coating principle is: the core yarn passes through the two threading holes on the two support seats under the action of traction. At the same time, the rotating cage as a whole is rotatably connected relative to the two support seats, and the transmission gear can be connected to the power source, so that the rotating cage as a whole continues to rotate at a uniform speed. At the same time, since the second gear is engaged with the fixed toothed disc, the second gear will also rotate synchronously, thereby driving all the first gears and the lead rollers to rotate. The coated yarn is continuously wound on all the lead rollers, and the adjacent lead rollers are close to each other. Therefore, the friction between the coated yarn and the lead roller is large, and it is not easy for the two to slip. Under the active traction of the lead roller, the bobbin sleeved on the bobbin shaft will rotate passively, thereby realizing the constant speed feeding of the coated yarn. These coated yarns will be wound on the core yarn at a fixed feeding speed and rotation speed, thereby achieving a uniform winding effect.

[0007] Furthermore, three wire guide rollers are provided, and the outer sides of the wire guide rollers are wrapped with rubber rings, and adjacent rubber rings are pressed against each other. The function of the rubber rings is to increase the friction with the yarn, further prevent the yarn from slipping on the wire guide roller, and ensure that the output speed of the yarn is constant.

[0008] Furthermore, a bearing sleeve is sleeved on the outer side of the spool shaft, which can significantly reduce the friction between the spool and the spool shaft, and a U-shaped groove is provided in the area corresponding to the spool shaft on the first annular sheet. One end of the spool shaft of the present invention is fixed to the second annular sheet, and the other end faces the U-shaped groove, so that the spool can be easily replaced.

[0009] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The present invention maintains a fixed ratio between the feeding speed and the winding speed of the covered yarn through the transmission connection between multiple gears. Therefore, it is only necessary to ensure that the introduction speed of the core yarn matches it, so that the composite yarn produced by the present invention can have a very constant performance.

There are more than three second connecting rods 152 connected in between, the first annular plate is coaxially fixed with the second annular plate, and a number of positioning rods 70 are riveted or bolted between the two, the fixed toothed disc is fixed relative to the two support seats and is coaxially arranged with respect to the core yarn, the yarn guiding module is arranged in a circular array between the two annular plates, including a bobbin shaft 131 fixed on the two annular plates and three mutually fitted lead rollers 132, one end of all the lead rollers is coaxially fixed with a first gear 133, all the first gears are meshed with each other, and the other end of a lead roller is coaxially fixed with a second gear 134, the second gear is meshed with the fixed toothed disc, and a coated yarn bobbin 135 is rotatably provided on the bobbin shaft, and the coated yarn on the coated yarn bobbin is wound into the core yarn after being guided by the lead roller.

[0016] This embodiment does not include a structure for pulling and stretching the core yarn, so this embodiment needs to be combined with the existing core yarn pulling and stretching equipment. The specific coating principle is: the core yarn passes through the two threading holes on the two support seats under the action of traction. At the same time, the rotating cage as a whole is rotated relative to the two support seats, and the transmission gear can be connected to the power source, so that the rotating cage as a whole continues to rotate at a uniform speed. At the same time, since the second gear is engaged with the fixed toothed disc, the second gear will also rotate synchronously, thereby driving all the first gears and the lead rollers to rotate. The coated yarn is continuously wound on all the lead rollers, and the adjacent lead rollers are close to each other. Therefore, the friction between the coated yarn and the lead roller is large, and it is not easy for the two to slip. Under the active traction of the lead roller, the bobbin sleeved on the bobbin shaft will rotate passively, thereby realizing the constant speed feeding of the coated yarn. These coated yarns will be wound on the core yarn at a fixed feeding speed and rotation speed, thereby achieving a uniform winding effect.

[0017] For details, see Figure 1 There are three wire guide rollers, and the outer side of the wire guide rollers is wrapped with rubber rings 136, and adjacent rubber rings are squeezed against each other. The function of the rubber rings is to increase the friction with the yarn, further prevent the yarn from slipping on the wire guide rollers, and ensure that the output speed of the yarn is constant.

[0018] For details, see Figure 1The outer side of the spool shaft is also sleeved with a bearing sleeve 137, which can significantly reduce the friction between the spool and the spool shaft. The first annular sheet is provided with a U-shaped groove 142 in the area corresponding to the spool shaft. One end of the spool shaft of this embodiment is fixed to the second annular sheet, and the other end faces the U-shaped groove, so that the spool can be easily replaced.

[0019] For details, see Figure 1 The second annular sheet is also provided with a guide wheel frame 160 and a guide wheel 161, and the rotation axis of the guide wheel is perpendicular to the core yarn. The guide wheel is used to guide the covering yarn drawn from the lead roller to the core yarn, so that the covering yarn is wound on the core yarn, and the core yarn is in a state of being transported backward, so the actual winding position will be biased to the rear side. In order to prevent the covering yarn from deviating too much from the middle position of the lead roller, the present invention introduces a guide wheel.

[0020] For details, see Figure 1 The yarn lead module also includes a trumpet tube 170 between the bobbin shaft and the lead-in roller, and the trumpet tube has a larger opening near one side of the bobbin shaft. The function of the trumpet tube is to introduce the yarn flowing out of the bobbin into the lead-in roller in a centered state.

[0021] The present invention can be modified in various ways which are obvious to those skilled in the art, and such modifications are not considered to depart from the scope of the present invention. All such modifications which are obvious to those skilled in the art are intended to be included within the scope of the present claims.
