Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn equipment technology, and more specifically, it relates to a yarn blocking device with anti-yarn skipping function. Background Technology
[0002] In modern weaving processes, yarn condition monitoring is crucial for ensuring product quality and production efficiency. Yarn undergoes various complex motion states during weaving, such as sudden acceleration and abrupt stops. These changes place high demands on the accuracy and stability of yarn condition monitoring sensors.
[0003] Existing yarn blocking devices are mainly installed on yarn condition monitoring sensors. The yarn blocking device allows yarns of a certain thickness and with knots of a certain size to pass through. The main purpose of the yarn blocking device is to prevent the yarn from swaying radially and getting tangled on the sensor components. When the yarn suddenly accelerates from a stationary state, or when the yarn moves quickly and stops abruptly, the yarn may sometimes cause huge jumps in the longitudinal direction, which is called yarn skipping. Yarn skipping may cause the yarn to jump out of the detection area. However, due to the limitations of the yarn application, a tensioning mechanism cannot be set on the yarn blocking device to restrain the yarn.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a yarn blocking device with anti-yarn skipping function.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a yarn-blocking device with anti-yarn-skipping function, comprising a plastic body and a first ceramic eye, wherein a limiting component is provided on the plastic body, the limiting component comprising a second ceramic eye, an elastic element and a sliding plastic element, a limiting tray is snapped onto the plastic body, and a groove is formed between the limiting tray and the plastic body to accommodate the sliding of the sliding plastic element, the elastic element is located between the sliding component and the groove, the second ceramic eye is detachably connected to the sliding plastic element, the elastic element includes a normal state and a compressed state, the length of the elastic element is greater than the length of the groove, when the sliding plastic element is located in the groove, the elastic element is in a compressed state, and the second ceramic eye and the first ceramic eye are misaligned with each other.
[0007] The present invention is further configured such that: a through groove is provided on the sliding plastic part, and a limiting boss is provided on the inner wall of the through groove; when the second ceramic eye is engaged in the through groove, the top surface of the limiting boss abuts against the second ceramic eye.
[0008] The present invention is further configured such that: a straight groove is provided on the limiting tray, the width of the straight groove is equal to the outer diameter of the second ceramic eye, and the length of the straight groove is greater than the outer diameter of the second ceramic eye.
[0009] The present invention is further configured such that: the limiting tray is provided with a plurality of buckles, and the plastic body is provided with a slot for accommodating the buckles; the slot connects the top surface and the bottom surface of the plastic body.
[0010] The present invention is further configured such that: the bottom surface of the plastic body is provided with a limiting protrusion, the limiting tray is provided with a limiting groove for accommodating the insertion of the limiting protrusion, and the limiting protrusion is provided with rounded corners.
[0011] The present invention is further configured such that: each of the buckles and limiting protrusions has two and is symmetrically arranged on the limiting tray and the plastic body respectively, and the two limiting protrusions are distributed on both sides of the two buckles.
[0012] The present invention is further configured such that the elastic element is a lightweight spring.
[0013] In summary, this utility model has the following beneficial effects: by setting a limiting component, the yarn is constrained by the limiting component when passing through the ceramic eye. Even in complex motion states such as sudden acceleration or sudden stop of the yarn, the longitudinal jump of the yarn can be effectively reduced, avoiding the occurrence of yarn skipping. At the same time, it ensures that the yarn is always within the effective detection area of the yarn status monitoring sensor, avoiding detection errors caused by the yarn jumping out of the detection area.

They are only for the convenience of describing this utility model and do not indicate that the device referred to must have a specific orientation or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0027] A yarn-blocking device with anti-yarn-skimming function, such as Figure 1 As shown, the device includes a plastic body 1 and a first ceramic eye 2. The plastic body 1 serves as the base of the entire device, supporting and fixing other components. The first ceramic eye 2 is installed on the plastic body 1 to guide the initial direction of the yarn and ensure that the yarn can smoothly enter the subsequent limiting component 3.
[0028] A limiting component 3 is provided on the plastic body 1. This limiting component 3 is the core part of this utility model. Specifically, it mainly includes a second ceramic eye 4, an elastic element 5, and a sliding plastic element 6. The function of the limiting component 3 is to constrain the movement of the yarn and reduce the jumping of the yarn in complex motion states, thereby improving the accuracy and stability of yarn condition monitoring. Specifically, the elastic element 5 is a lightweight spring. The selection of a lightweight spring ensures that the elastic element 5 provides sufficient buffering force without generating excessive resistance to the normal movement of the yarn, ensuring that the yarn can pass smoothly. At the same time, it can also quickly respond to changes in yarn tension, further improving the adaptability and stability of the device.
[0029] A limiting tray 7 is snapped onto the plastic body 1, and a groove 8 is formed between the limiting tray 7 and the plastic body 1. The groove 8 is used to accommodate the sliding plastic part 6. The sliding plastic part 6 can slide freely in the groove 8, thereby adaptively adjusting according to the tension and movement state of the yarn. The elastic element 5 is located between the sliding plastic part 6 and the groove 8, playing a role in buffering and adjustment. The length of the elastic element 5 is greater than the length of the groove 8, so that the elastic element 5 is always in a compressed state under normal conditions. It can automatically adjust its compression degree according to the change of yarn tension, thereby adapting to the operating requirements of different yarns and improving the versatility and adaptability of the device.
[0030] The second ceramic eye 4 is detachably connected to the sliding plastic part 6, which facilitates the replacement or repair of the second ceramic eye 4, improves the maintenance convenience of the device, and reduces maintenance costs. When the sliding plastic part 6 is located in the slide groove 8, the elastic part 5 is in a compressed state. At this time, the second ceramic eye 4 and the first ceramic eye 2 are misaligned. This misalignment design can give the yarn a certain guiding and stabilizing effect when passing through the two ceramic eyes, reduce the shaking and deviation of the yarn, so that the yarn condition monitoring sensor can collect the movement information of the yarn more accurately and improve the detection accuracy.
[0031] A through groove 9 is provided on the sliding plastic part 6, and a limiting boss 10 is provided on the inner wall of the through groove 9. When the second ceramic eye 4 is engaged in the through groove 9, the top surface of the limiting boss 10 presses against the second ceramic eye 4. The function of the limiting boss 10 is to ensure the stable fixation of the second ceramic eye 4 on the sliding plastic part 6, and to prevent the second ceramic eye 4 from loosening or shifting during the movement of the yarn, thereby ensuring the stable passage of the yarn through the ceramic eye and providing a strong guarantee for the accurate detection of the sensor.
[0032] The limiting tray 7 has a straight groove 11. The width of the straight groove 11 is equal to the outer diameter of the second ceramic eye 4, and the length of the straight groove 11 is greater than the outer diameter of the second ceramic eye 4. The design of the straight groove 11 allows the second ceramic eye 4 to slide along the straight groove 11 under the action of the sliding plastic part 6, while restricting the lateral movement of the second ceramic eye 4, which further enhances the stability of the yarn.
[0033] The limiting tray 7 is provided with several buckles 12, and the plastic body 1 has a slot 13 for receiving the buckles 12. The slot 13 connects the top and bottom surfaces of the plastic body 1. This matching method of the buckles 12 and the slot 13 makes the connection between the limiting tray 7 and the plastic body 1 firm and reliable, which can ensure the stability of the entire device during long-term use, reduce detection errors caused by loosening or deformation of the device's own structure, and further improve the stability of detection.
[0034] The bottom surface of the plastic body 1 is provided with a limiting protrusion 14, and the limiting tray 7 is provided with a limiting groove 15 to accommodate the insertion of the limiting protrusion 14. The limiting protrusion 14 is provided with rounded corners. The rounded corner design facilitates the smooth insertion of the limiting protrusion 14 into the limiting groove 15, and also reduces stress concentration that may be caused by sharp edges, thereby improving the durability of the device. The cooperation between the limiting protrusion 14 and the limiting groove 15 further enhances the connection stability between the limiting tray 7 and the plastic body 1, ensuring the reliability of the device during operation. Furthermore, there are two buckles 12 and two limiting protrusions 14, which are symmetrically arranged on the limiting tray 7 and the plastic body 1 respectively. The two limiting protrusions 14 are distributed on both sides of the two buckles 12. This symmetrical structural design not only makes the structure of the device more stable, but also enables faster and more accurate positioning and assembly during installation, improving installation efficiency, reducing installation errors, and ensuring the installation quality of the device.
[0035] In practical use, workers use a hook to pass the yarn through the second ceramic eye 4 and the first ceramic eye 2 in sequence. Since the diameter of the upper and lower ceramic eyes is the same as before, it does not affect the passage of thicker yarns and knotted yarns. When the yarn experiences complex motion states such as sudden acceleration or sudden stop during the production process, the compression state of the elastic element 5 can buffer the movement of the yarn and reduce the yarn jump. The top surface of the limiting boss 10 presses against the second ceramic eye 4 to ensure the stable fixation of the second ceramic eye 4 on the sliding plastic part 6. The connection structure between the limiting tray 7 and the plastic body 1 is firm and reliable, ensuring the stability of the device. Through the above structural design, the yarn blocking device of this utility model can effectively prevent yarn jump and improve the accuracy and stability of yarn condition monitoring.
[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
