Description

Technical Field

[0001] The utility model belongs to the technical field of polyester processing, and particularly relates to a polyester yarn texturizing device. Background Art

[0002] Polyester yarn has strong corrosion resistance and washing resistance, but its elasticity is poor. The existing technology enhances the elasticity of polyester yarn by winding spandex yarn around the outside of the polyester yarn. However, the existing polyester yarn elasticizing device is prone to loosening of the yarn during the winding process, resulting in poor elasticizing effect.

[0003] The existing polyester yarn texturizing device uses a method of adjusting the distance between the yarn winding roller and the discharge roller to adjust the winding tightness. However, this adjustment method is difficult to fine-tune and may result in over-adjustment, causing the yarn to break. Therefore, the existing polyester yarn texturizing device lacks a convenient device for adjusting the winding tightness, and the device is not easy to break due to excessive tension of the yarn. Utility Model Content

[0004] The purpose of the present invention is to solve the problems described in the above background technology. A new polyester yarn elasticizing device is proposed. The polyester yarn elasticizing device can effectively adjust the tightness of the winding yarn and is provided with a buffer structure to prevent the yarn from breaking.

[0005] A technical solution adopted to achieve the above-mentioned purpose is a polyester yarn texturizing device, which comprises:

[0006] A base, wherein a mounting frame is provided on the base;

[0007] An installation unit, the installation unit comprising an installation box, a first motor and a plurality of rotating rollers, the installation box being rotatably connected to the installation frame, the output end of the motor being connected to the installation box via a belt transmission, a plurality of limiting holes and a central through hole being provided on one side wall of the installation box, a buffer unit being provided in each limiting hole;

[0008] The buffer unit includes a limiting tube and a plurality of elastic members, wherein the elastic members connect the peripheral side of the limiting tube and the inner wall of the limiting hole.

[0009] In the above technical solution, the output of the silk thread is limited by the limiting holes and the central through hole, which plays a guiding and limiting role on the silk thread to prevent the silk thread from being tangled and chaotic, and a buffer section is reserved for the silk thread through the above-mentioned limiting holes. When the winding tightness is increased, the silk thread can press the elastic part to play a buffering role to prevent the wire from breaking, and reduce the friction force of the silk thread passing through the limiting tube, further reducing the possibility of the silk thread breaking due to friction during winding.

[0010] Furthermore, the polyester yarn texturizing device also includes a limiting unit, which includes a support seat, a limiting plate and a limiting plate bracket. The limiting plate is arranged on the top of the support seat, and the limiting plate is rotatably connected to the limiting plate bracket.

[0011] Furthermore, the limiting plate is provided with a plurality of second limiting holes corresponding to the limiting holes and the central through hole.

[0012] In the above technical solution, the polyester and spandex threads are further limited by the limiting disk to prevent the threads from becoming disordered and the winding structure from becoming disordered.

[0013] Furthermore, the polyester yarn elasticizing device also includes a transmission unit, which includes two transmission rollers, a transmission roller bracket and a second motor. The transmission roller is rotatably connected to the transmission roller bracket, and the output end of the second motor is fixedly connected to the rotating shaft of one of the transmission rollers.

[0014] In the above technical solution, the silk thread is driven into the next mechanism unit by the transmission unit, and the winding tightness of the silk thread after winding and combining can be enhanced by squeezing the two transmission rollers.

[0015] Furthermore, the polyester yarn elasticizing device also includes a tensioning unit, which includes a mounting ring, a plurality of studs, a plurality of threaded sleeves and a plurality of friction plates. The studs are fixed to the circumferential side of the mounting ring, the threaded sleeves are connected to the studs through threads, and the friction plates are fixed to one side end of the threaded sleeves.

[0016] In the above technical solution, the distance between the friction plate and the rotating roller can be adjusted by rotating the threaded sleeve. When the wire winding is loose, the contact between the friction plate and the rotating roller can increase the resistance of the rotating roller, thereby increasing the tension of the wire.

[0017] Furthermore, the rotating roller is located on the extension line of the stud axis.

[0018] Furthermore, the plurality of limiting holes are evenly spaced around the central through hole.

[0019] In the above technical solution, the evenly spaced arrangement enables the spandex yarn to be evenly wound around the polyester yarn, thereby enhancing the elasticity of the polyester yarn.

[0020] Furthermore, the buffer unit is provided with a limiting tube and four elastic members, and the four elastic members are symmetrically arranged in pairs on the circumference of the limiting tube.

[0021] In the above technical solution, the elastic members are symmetrically arranged in pairs, so that during the rotation of the mounting unit, the limiting tube can move between the elastic members, thereby playing a good buffering role.

[0022] The advantages of the present invention are:

[0023] 1. The utility model prevents the wire from being broken due to excessive tension by providing an elastic member and a limiting tube.

[0024] 2. The utility model adjusts the pressure of the friction plate on the rotating roller through the cooperation of the stud and the threaded sleeve, thereby adjusting the resistance encountered by the rotating roller during rotation, thereby achieving the purpose of adjusting the tension of the silk thread. This adjustment method is more precise and can be adjusted for different spandex yarns separately. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] like Figure 1 As shown, a polyester yarn texturizing device includes a base 1 and a mounting unit 2. A mounting frame 101 is provided on the top of the base 1. The mounting unit includes a mounting box 201, a first motor 202 and a plurality of rotating rollers 203. A rotating shaft portion is provided on the left side of the mounting box. The mounting box is rotatably connected to the mounting frame through the rotating shaft portion. The output end of the motor and the rotating shaft portion of the mounting box are driven by a belt. The right side wall of the mounting box is provided with a plurality of limiting holes 204 and a central through hole 205, and each limiting hole is provided with a buffer unit 3.

[0034] In this embodiment, seven rotating rollers are provided, one of which is arranged at the center of the mounting box, and the remaining six rotating rollers are evenly spaced around the central rotating roller. The number of limiting holes is the same as the number of rotating rollers arranged on the peripheral sides, and the six limiting holes correspond to six rotating rollers respectively.

[0035] Buffer unit such as Figure 2 As shown, it is composed of a limiting tube 301 and a plurality of elastic members 302 , and the elastic members connect the peripheral side of the limiting tube and the inner wall of the limiting hole.

[0036] In this embodiment, four elastic members are provided. The elastic members are springs. The four elastic members are symmetrically arranged in pairs on the circumference of the limiting tube.

[0037] In one embodiment, the polyester yarn elasticizing device is further provided with a limiting unit 4, which consists of a support seat 401, a limiting plate 402 and a limiting plate bracket 403. The support seat is arranged on the base, the limiting plate bracket is fixed to the top of the support seat, and the limiting plate can be rotatably installed on the limiting plate bracket.

[0038] In one embodiment, if Figure 3 As shown, the limiting plate is provided with a plurality of second limiting holes 404 corresponding to the limiting holes and the central through hole.

[0039] In one embodiment, the polyester yarn elasticizing device is further provided with a transmission unit, which consists of two transmission rollers 501, a transmission roller bracket 502 and a second motor 503, wherein the transmission roller is rotatably connected to the transmission roller bracket, and the output end of the second motor is fixedly connected to the rotating shaft of one of the transmission rollers.

[0040] In one embodiment, if Figure 4 As shown, the polyester yarn texturizing device is also provided with a tensioning unit 6, which consists of a mounting ring, a plurality of studs 601, a plurality of threaded sleeves 602 and a plurality of friction plates 603. The studs are fixed to the circumferential side of the mounting ring, the threaded sleeves are connected to the studs by threads, the friction plates are fixed to one end of the threaded sleeves, and the mounting ring is fixed in the mounting box. The number of studs, threaded sleeves and friction plates is the same as the number of limiting holes.

[0041] In one embodiment, the tensioning unit is provided with six studs, six threaded sleeves and six friction plates, and the six rotating rollers are respectively located on the extension lines of the corresponding stud axes.

[0042] The working principle and process of this utility model:

[0043] A polyester roll is mounted on the central rotating roller, and a spandex roll is mounted on the peripheral rotating roller. The polyester filament passes through the central through hole and continues to pass through the second central limiting hole of the limiting disk. The spandex filament passes through the corresponding limiting holes respectively and continues to pass through the second peripheral limiting holes of the limiting disk. It is pulled and transmitted through the transmission unit. At this time, the first motor drives the installation box to rotate, and the six spandex rolls on the peripheral side of the installation box rotate relative to the polyester roll, so that the spandex filament is wound around the polyester filament.

[0044] If the winding is too loose, stop the motor and rotate the threaded sleeve to drive the friction plate into contact with the rotating shaft of the peripheral rotating wheel. By adjusting the degree of rotation of the threaded sleeve, adjust the rotational resistance of the rotating wheel to tighten the spandex yarn.

[0045] When the spandex thread is too tight, the spandex thread drives the limit tube to move toward the center of the installation box, and is buffered by the elastic part to prevent the thread from breaking.

[0046] Finally, it should be noted that the present embodiment is intended only to illustrate the present invention and does not limit the scope of the present invention. In addition, it should be understood that after reading the contents of the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
