Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology and relates to a POY filament cutting and adsorption device. Background Technology

[0002] In the production process of polyester POY (pre-oriented yarn), texturing and finishing is a crucial step, and its success rate directly affects product quality and production efficiency. However, in practice, finishing has always been a relatively weak link, especially the quality of the bottom layer yarn, which has a direct impact on the success rate of texturing and finishing.

[0003] The reasons for poor quality of the bottom layer yarn are varied, with abnormal oil content, poor saturation leading to yarn dispersion, and knots causing poor unwinding being particularly prominent. Knotting is especially troublesome, primarily because during POY production, lint and fly filaments generated during yarn starting and switching are easily caught inside the yarn cake, affecting the continuity and uniformity of the bottom layer yarn. The presence of these fly filaments not only reduces the quality of the bottom layer yarn but can also lead to difficulties in subsequent unwinding and processing, thus impacting the stability and efficiency of the entire production line.

[0004] To improve the quality of the base yarn and increase the success rate of texturing and finishing, patent CN219690052U controls the amount of oil applied to the base yarn to increase its oiliness and counteract the oil absorption phenomenon of the paper tube, thereby improving the cohesion and quality of the base yarn. Patent CN112746363B controls the size of the compression to increase the network points of the base yarn, thereby improving the cohesion of the yarn and thus improving the finishing rate. However, while these methods improve the quality of the base yarn to some extent, they do not fundamentally solve the problem of fly waste getting caught in the yarn cake due to the start-up yarn beating and switching actions.

[0005] In actual production, since polyester POY is mostly a porous fine denier variety, monofilament breakage is unavoidable during the starting and switching operations, so fly waste is an objective phenomenon. Although traditional tail-spinning rods (filament cutters) can control the position of the filament bundle and cut the filaments, their enclosed cavity rod structure makes it easy for fly waste to be carried into the yarn cake, thus causing knotting problems. Utility Model Content

[0006] The purpose of this invention is to solve the problems existing in the prior art and to provide a POY shredding and adsorption device.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A POY shredding and adsorption device includes a tail rod and a ceramic component. The tail rod has a hollow structure and a groove on its outer wall for clamping the ceramic component. The groove is parallel to the axial direction of the tail rod. The device also includes a negative pressure device. The bottom of the groove has an air intake. One end of the tail rod is sealed, and the other end is connected to the negative pressure device.

[0009] As a preferred technical solution:

[0010] As described above, the POY shredding and adsorption device has an elongated air inlet that is parallel to the axial direction of the tail rod.

[0011] As described above, a POY shredding and adsorption device has an air intake between any two adjacent ceramic pieces.

[0012] As described above, the POY shredding and adsorption device has a distance of 118mm between any two adjacent ceramic parts, a length of 110mm for the air intake, and a width of 4mm for the slit.

[0013] As described above, in a POY shredding and adsorption device, all the air inlets are evenly spaced along the axial direction of the tail rod.

[0014] The POY shredding and adsorption device described above also includes a spare spindle.

[0015] The POY shredding and adsorption device described above also includes an infrared identification device for identifying whether the spare spindle is rotating. When the infrared identification device is present, the operator can activate the negative pressure device when the infrared identification device indicates that the spare spindle is rotating. When the infrared identification device is absent, the operator can directly read the equipment operation signal from the machine and activate the negative pressure device when it is determined that the spare spindle is rotating.

[0016] The POY shredding and adsorption device described above also includes a sensor for identifying whether the tail rod has returned to its original position. When the sensor is present, the operator can control the negative pressure device to continue working for 30 seconds and then stop working when the sensor indicates that the tail rod has returned to its original position. When the sensor is absent, the operator can read the data inside the machine to obtain the signal that the shredder has started to wind, and then control the negative pressure device to continue working for 30 seconds and then stop working.

[0017] Beneficial effects:

[0018] This invention adds a negative pressure suction function to the POY filament cutting and adsorption device by setting an air inlet on the tail rod and connecting it to a negative pressure device. This effectively removes fly waste generated during the initial yarn beating and switching, preventing it from being rolled into the yarn cake and causing knots. This significantly improves the quality of the bottom layer yarn. At the same time, the continuity and uniformity of the bottom layer yarn are improved, thereby enhancing the overall quality of the bottom layer yarn and providing better conditions for subsequent unwinding and processing. In addition, the improvement in the quality of the bottom layer yarn directly helps to increase the success rate of texturing and finishing, thereby enhancing the stability and efficiency of the production line and reducing production losses caused by finishing failures.

[0022] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0023] A POY shredded adsorption device, such as Figure 1 and Figure 2 As shown, it includes a tail-swing bar 1, a ceramic component 2, a negative pressure device 4, a spare spindle 6, an infrared identification device, and a sensor;

[0024] like Figure 2 As shown, the tail boom 1 has a hollow structure, one end of the tail boom 1 is sealed, and the other end is connected to the negative pressure device 4;

[0025] The outer wall of the drift rod 1 is provided with a groove 3, which is parallel to the axial direction of the drift rod 1. The width of the groove 3 is 4mm, and the groove 3 is used to clamp the ceramic part 2.

[0026] The bottom of the groove 3 is provided with an air intake 5. The air intake 5 is long and parallel to the axis of the tail rod 1. An air intake 5 is provided between any two adjacent ceramic parts 2. All the air intakes 5 are distributed at equal intervals along the axis of the tail rod 1. The distance between any two adjacent ceramic parts 2 is 118mm, and the length of the air intake 5 is 110mm.

[0027] Before starting or switching the yarn, the spare spindle begins to rotate. Simultaneously, an infrared recognition device detects this rotation. When the infrared recognition device indicates the spare spindle is rotating, the operator can activate the negative pressure device. Upon receiving the activation signal, the negative pressure device begins operation, creating a negative pressure zone through the suction port on the tail rod. During the starting or switching process, when the tail rod contacts and rubs against or cuts the yarn, the resulting fly shavings and fuzz are sucked away by the negative pressure zone and ultimately collected or discharged. When the yarn begins to wind, the sensor detects that the tail rod has returned to its original position. When the sensor indicates the tail rod has returned to its original position, the operator can control the negative pressure device to continue operating for 30 seconds before stopping, completing the adsorption and cleaning process.
