Description

Technical Field

[0001] This utility model relates to the field of weft feeder technology, specifically a weft feeder with a yarn breakage detection device. Background Technology

[0002] A weft feeder is a device used on textile equipment to process yarn. This device can adjust the tension of the yarn and make the tension of all yarns uniform, thereby avoiding yarn breakage due to excessive tension and preventing the textile equipment from failing to operate due to insufficient tension. In order to improve the processing quality of yarn, weft feeders with yarn breakage detection devices have been developed.

[0003] The existing weft feeders with yarn breakage detection devices are usually equipped with detectors to detect breakage of the yarn wound on the weft feeder. However, since the yarn is usually wound evenly on the weft feeder, the existing detectors are not convenient for detecting yarn in different areas, which reduces the detection accuracy.

[0004] To address this issue, we designed a weft feeder with a yarn breakage detection device. Utility Model Content

[0005] The purpose of this invention is to provide a weft feeder with a yarn breakage detection device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a weft feeder with a yarn breakage detection device, including a weft feeder body. A support member is fixedly installed on one side of the weft feeder body. A triangular block is provided at one end of one side of the support member. A rotating shaft is rotatably provided on one side of the triangular block. A fixing block is fixedly sleeved at the center of the rotating shaft. A connecting rod is provided on one side of the fixing block. A CCD camera is fixedly installed at the other end of the connecting rod. The CCD camera faces the area of ​​the weft feeder body where the yarn is wound. A gear is fixedly sleeved on the rotating shaft. A driving member is provided inside the triangular block. The driving member is connected to the gear for transmission.

[0007] Furthermore, a fixing groove is provided on one side of the triangular block, and the rotating shaft is rotatably disposed in the fixing groove.

[0008] Furthermore, the driving component includes an electric push rod, which is fixedly installed on the top of the inner sidewall of the fixed groove. The driving end of the electric push rod is provided with a rack, which meshes with a gear.

[0009] Furthermore, bearings are fixedly installed on both the top and bottom walls of the fixed groove, and the two ends of the rotating shaft are respectively fixedly inserted into the inner rings of the two bearings.

[0010] Furthermore, a limiting rod is provided at the bottom of the fixing block, and a ball is rotatably provided at the bottom of the limiting rod. An annular groove is provided in the fixing groove, and the ball is rotatably connected in the annular groove.

[0011] Furthermore, the limiting rod has an installation cavity and a placement groove respectively inside and at its bottom. The installation cavity is connected to the placement groove. The ball is rotatably installed in the installation cavity and the placement groove, and the bottom of the ball is located outside the placement groove.

[0012] Furthermore, there are two limiting rods, and the two limiting rods are symmetrically fixedly installed at the bottom of the fixing block.

[0013] Furthermore, an electrical box is provided on one side of the triangular block, and the electrical box is electrically connected to the electric push rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by activating the electric push rod, the drive end of the electric push rod can reciprocate to drive the rack to move horizontally back and forth in the fixed groove. During this process, the rack will drive the gear and the rotating shaft to rotate forward and backward, which can adjust the detection range of the CCD camera, thereby improving the effect of yarn breakage detection.

[0015] Compared with the prior art, the beneficial effects of this utility model are: during the rotation of the rotating shaft, the fixed block will drive the limiting rod and the ball to roll in the annular groove, which can not only limit the fixed block and improve its stability, but also change the sliding friction of the limiting structure to rolling friction, thereby reducing the friction force and thus reducing friction loss.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a weft feeder with a yarn breakage detection device, comprising a weft feeder body 1, a support member 2 fixedly installed on one side of the weft feeder body 1, a triangular block 3 provided at one end of one side of the support member 2, a rotating shaft 4 rotatably provided on one side of the triangular block 3, a fixing block 5 fixedly sleeved at the center of the rotating shaft 4, a connecting rod 6 provided on one side of the fixing block 5, a CCD camera 7 fixedly installed at the other end of the connecting rod 6, the CCD camera 7 facing the area of ​​the weft feeder body 1 where the yarn is wound, a gear 8 fixedly sleeved on the rotating shaft 4, a driving member provided inside the triangular block 3, the driving member being connected to the gear 8 in a transmission manner, the driving member including an electric push rod 9, the electric push rod 9 being fixedly installed on the top of the inner side wall of the fixing groove 11, a rack 10 provided at the driving end of the electric push rod 9, the rack 10 being meshed with the gear 8.

[0023] In practice, when it is necessary to detect the breakage of the yarn wound at high speed on the weft feeder body 1, first turn on the CCD camera 7 and make the CCD camera 7 face the yarn on the weft feeder body 1 to detect the breakage of the yarn, which can facilitate the detection of yarn breakage and improve the quality of yarn processing.

[0024] During the above detection process, the electric push rod 9 is turned on, causing the drive end of the electric push rod 9 to reciprocate and extend, driving the rack 10 to move horizontally back and forth in the fixed groove 11. During this process, the rack 10 will drive the gear 8 and the rotating shaft 4 to rotate forward and backward, which can adjust the detection range of the CCD camera 7, thereby improving the effect of yarn breakage detection.

[0025] It should be noted that the main body 1 of the weft feeder typically consists of a motor, a yarn storage drum, a yarn winding disc, a yarn quantity detector, a damping ring, a tensioner, and a yarn feeding mechanism. Its general principle is as follows: 1. Storing weft yarn: The weft feeder temporarily stores the weft yarn unwound from the bobbin, usually wound on the yarn storage drum, awaiting the weft insertion moment. During this process, the design of the yarn storage drum ensures the weft yarn is neatly arranged, creating favorable conditions for weft insertion; 2. Maintaining stable tension: The weft feeder controls the tension of the weft yarn through internal components such as the tensioner and damping ring, preventing the yarn from being too slack or too tense, ensuring a stable supply of weft yarn in the loom. This helps reduce tension fluctuations caused by changes in the bobbin unwinding diameter and improves tension uniformity; 3. Adapting to high-speed weaving: The weft feeder is designed to adapt to shuttleless looms with high weft insertion rates, ensuring a continuous supply of weft yarn during high-speed weaving. By temporarily storing the weft yarn, a stable supply of weft yarn can be ensured during weft insertion, thereby improving weaving efficiency and fabric quality. Since the main body of the weft yarn holder 1 is existing technology and is not a problem that needs to be solved in the background technology of this description, it will not be elaborated on further.

[0026] Furthermore, the CCD camera 7 relies entirely on the CCD sensor for imaging. When light shines on the photosensitive units of the CCD, each unit converts the received photons into electrical charges. These charges are then transmitted line by line within the CCD, eventually reaching the readout register and being converted into a voltage signal. Specifically, in this specification, a good image can be embedded within the CCD. When the CCD camera 7 scans an object, it automatically compares the image with the good image. If a difference is found, it indicates that the detected object is defective. Since the CCD camera 7 is existing technology and not a problem that needs to be solved in the background of this specification, it will not be elaborated upon further.

[0027] See Figure 1-4 A fixing groove 11 is provided on one side of the triangular block 3, and the rotating shaft 4 is rotatably mounted in the fixing groove 11. This allows for the proper installation of components within the triangular block 3, avoiding motion interference issues.

[0028] See Figure 1-4 Bearings 12 are fixedly installed on both the top and bottom walls of the fixed groove 11, and the two ends of the rotating shaft 4 are respectively fixedly inserted into the inner rings of the two bearings 12. This facilitates the rotation of the rotating shaft 4 within the fixed groove 11.

[0029] See Figure 1-4 The bottom of the fixed block 5 is provided with a limiting rod 13, and a ball bearing 14 is rotatably provided at the bottom of the limiting rod 13. An annular groove 15 is provided in the fixing groove 11, and the ball bearing 14 is rotatably connected in the annular groove 15. The inside and bottom of the limiting rod 13 are respectively provided with an installation cavity and a placement groove. The installation cavity and the placement groove are connected. The ball bearing 14 is rotatably installed in the installation cavity and the placement groove, and the bottom of the ball bearing 14 is located outside the placement groove.

[0030] In specific implementation, based on the above implementation, during the rotation of the rotating shaft 4, the fixed block 5 will drive the limiting rod 13 and the ball 14 to roll in the annular groove 15. This not only limits the fixed block 5 and improves its stability, but also changes the sliding friction of the limiting structure to rolling friction, thereby reducing the friction force and thus reducing friction loss.

[0031] See Figure 1-4 There are two limiting rods 13, and the two limiting rods 13 are symmetrically fixedly installed at the bottom of the fixing block 5. The setting of two limiting rods 13 can ensure that the forces on both sides of the bottom of the fixing block 5 are balanced, thereby further improving its stability.

[0032] See Figure 1-4 An electrical box 16 is installed on one side of the triangular block 3, and the electrical box 16 is electrically connected to the electric push rod 9. By electrically connecting the electric push rod 9 and the electrical box 16 through a circuit, power can be supplied to the electric push rod 9, thereby ensuring the normal operation of the electric push rod 9.

[0033] Working principle: When it is necessary to detect the breakage of the yarn wound at high speed on the weft feeder body 1, first turn on the CCD camera 7 and make the CCD camera 7 face the yarn on the weft feeder body 1 to detect the breakage of the yarn, which can facilitate the detection of yarn breakage and improve the quality of yarn processing.

[0034] During the above detection process, the electric push rod 9 is turned on, causing the drive end of the electric push rod 9 to reciprocate and extend, driving the rack 10 to move horizontally back and forth in the fixed groove 11. During this process, the rack 10 will drive the gear 8 and the rotating shaft 4 to rotate forward and backward, which can adjust the detection range of the CCD camera 7, thereby improving the effect of yarn breakage detection.

[0035] It should be noted that during the rotation of the rotating shaft 4, the fixed block 5 will drive the limiting rod 13 and the ball 14 to roll in the annular groove 15. This not only limits the fixed block 5 and improves its stability, but also changes the sliding friction of the limiting structure to rolling friction, thereby reducing the friction force and thus reducing friction loss.
