Description

Technical Field

[0001] This utility model relates to the field of yarn sensor technology, and in particular to a yarn sensor that is easy to install. Background Technology

[0002] Spinning is one of my country's traditional industries, and it is now generally produced in factories. Factories use automated machinery for processing. Typically, a single textile machine processes dozens or even hundreds of yarns simultaneously. During processing, yarn breakage is inevitable due to stress or deformation. Therefore, yarn sensors are used to monitor yarn continuity in real time during processing.

[0003] However, current yarn sensors are relatively large, requiring assembly via grooves or channels when installed on equipment. This occupies a significant amount of internal space, making wiring difficult. When a yarn sensor malfunctions, it hinders subsequent maintenance. Furthermore, accumulated oil and grease inside can also cause problems. In summary, conventional sensors cause inconvenience in production, installation, and maintenance, especially in emergencies, where their complex structure reduces maintenance efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a yarn sensor that is easy to install.

[0005] The technical solution of this utility model is: a yarn sensor that is easy to install, comprising:

[0006] The housing is square in shape and hollow inside, with an open end on one side and a detection end on the other side corresponding to the open end.

[0007] A detection notch is provided at the detection end, which is connected to the inside of the housing. A detection element is provided at the detection notch, and the detection element detects the yarn.

[0008] The detection component is installed into the housing from the open end using a quick-installation assembly, and the detection component is signal-connected to the detection element;

[0009] The mounting bracket is located on the outside of the housing and is used to fix the yarn sensor on the device. The distance between the mounting bracket and the open end is 0.5-2.5 cm.

[0010] Furthermore, the detection notch is U-shaped. The U-shaped notch facilitates the smooth entry of the yarn into the detection position.

[0011] Furthermore, the channel for detecting the notch is Y-shaped. The sloping sides effectively ensure the stability of the yarn entry process.

[0012] Furthermore, limiting protrusions are respectively provided on the inner walls of both sides of the detection notch, and the two limiting protrusions are correspondingly positioned with a gap between them. After the yarn enters the detection notch through the gap between the two limiting protrusions, the limiting protrusions effectively prevent the yarn from slipping out of the detection notch during operation.

[0013] Furthermore, mounting bosses are respectively provided inside the housing, and detection components are arranged between the mounting bosses. By fixing the detection components between the mounting bosses, the simplicity and stability of the installation process can be effectively improved.

[0014] Furthermore, the quick-installation component is a mounting screw, which is disposed within the housing. A quick-positioning element is also provided, comprising a quick-positioning rod and a quick-positioning hole. The quick-positioning rod engages with the detection component, and the quick-positioning hole engages with the mounting screw. That is, after the quick-positioning rod engages with the detection component, the mounting screw is inserted into the quick-positioning hole and fixedly connected to the housing, achieving rapid installation of the detection component. Typically, a Phillips head screw or a flathead screw is used.

[0015] Furthermore, the mounting screws are assembled with mounting bosses inside the housing.

[0016] Furthermore, the detection component is provided with a detection positioning hole, which cooperates with a quick positioning component. This ensures more stable assembly of the detection component.

[0017] Furthermore, the detection element is welded and fixed to the detection assembly. This stable connection method ensures stability during the yarn detection process.

[0018] Furthermore, the detection element is a photoelectric detection element or a capacitance detection element. The principles of these two detection yarns are mature technologies in the field and will not be elaborated further. Using wear-resistant ceramic materials can improve service life.

[0019] Furthermore, the detection component includes a detection circuit board, which is also provided with a connector facing the open end. The connector facilitates the rapid installation, replacement, and maintenance of multiple yarn sensors. The circuitry and electronic components on the circuit board can be configured according to actual needs.

[0020] Furthermore, the detection end of the housing is provided with a warning hole, and a warning light is installed inside the warning hole. The warning light is connected to the detection component. The detection component controls the warning light. When a yarn breakage or fault is detected, an alarm is triggered by the warning light, which is generally red. During normal operation, a green light may be displayed, or no light may be displayed, but an alarm will be triggered by the red warning light when a fault occurs.

[0021] Furthermore, the mounting plate is provided with at least one mounting hole. The housing is fixedly installed through the mounting hole, and since the mounting plate is located on the outside of the housing, it can provide a limiting function during assembly.

[0022] Furthermore, the mounting and fixing plate is arranged around the perimeter of the housing. If the detection end is defined as the front end, then the open end is the rear end, and the top, bottom, left, and right sides are the perimeter. The mounting and fixing holes can be set on the left and right sides to ensure stable installation.

[0023] Furthermore, the distance between the mounting bracket and the open end is 1-1.5 cm. The open end is inserted into the channel and secured by the mounting bracket.

[0024] The beneficial technical effects of this utility model are: by shortening the installation part of the yarn sensor, the internal space is increased while keeping the installation groove unchanged. The connector is located inside the groove, which facilitates the subsequent wiring layout. Furthermore, the increased internal space facilitates the cleaning of internal oil stains, preventing interference with the operation of the yarn sensor. In case of subsequent malfunction, the yarn sensor can be removed, the wire at the connector unplugged, and the quick-installation assembly unscrewed to remove the internal detection component. After replacing it with a suitable circuit board, reassembly allows for repair, improving the efficiency of subsequent maintenance. Attached Figure Description

[0038] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0039] See appendix Figure 1-7 As shown, this embodiment of a yarn sensor that is easy to install includes:

[0040] The housing 1 is square and hollow inside. One side of the housing 1 is an open end 11, and the other side corresponding to the open end 11 is a detection end 12.

[0041] A detection notch 13 is provided at the detection end 12. The detection notch 13 is connected to the inside of the housing 1. A detection element 2 is provided at the detection notch 13 to detect the yarn.

[0042] The detection component 4 is installed into the housing 1 from the open end 11 via the quick-installation assembly 3, and the detection component 4 is signal-connected to the detection element 2;

[0043] Mounting fixing piece 5 is located on the outside of housing 1, and the yarn sensor is fixedly mounted on the device by mounting fixing piece 5. The distance between mounting fixing piece 5 and open end 11 is 0.5-2.5 cm.

[0044] Furthermore, the detection notch 13 is U-shaped. The U-shaped notch design facilitates the smooth entry of the yarn into the detection position.

[0045] Furthermore, the detection gap 13 is Y-shaped. The sloping design on both sides effectively ensures the stability of the yarn entry process.

[0046] Furthermore, limiting protrusions 14 are respectively provided on the inner walls of both sides of the detection notch 13, and the two limiting protrusions 14 are correspondingly positioned with a gap between them. After the yarn enters the detection notch 13 through the gap between the two limiting protrusions 14, during operation, the limiting effect of the limiting protrusions 14 can effectively prevent the yarn from slipping out of the detection notch 13.

[0047] Furthermore, mounting bosses 15 are respectively provided inside the housing 1, and detection components 4 are arranged between the mounting bosses 15. By fixing the detection components 4 between the mounting bosses 15, the simplicity and stability of the installation process can be effectively improved.

[0048] Furthermore, the quick-installation component 3 is a mounting screw 31, which is disposed within the housing 1. A quick-positioning component 32 is also provided, comprising a quick-positioning rod 33 and a quick-positioning hole 34. The quick-positioning rod 33 engages with the detection component 4, and the quick-positioning hole 34 engages with the mounting screw 31. That is, after the quick-positioning rod 33 engages with the detection component 4, the mounting screw 31 is inserted into the quick-positioning hole 34 and fixedly connected to the housing 1, achieving quick installation of the detection component 4. Typically, a Phillips head screw or a flathead screw is used.

[0049] Furthermore, the mounting screw 31 is assembled with the mounting boss 15 inside the housing 1.

[0050] Furthermore, the detection component 4 is provided with a detection positioning hole 35, which is connected in conjunction with the quick positioning component 32. This ensures more stable assembly of the detection component 4.

[0051] Furthermore, the detection component 2 is welded and fixed to the detection assembly 4. This stable connection method ensures stability during the yarn detection process.

[0052] Furthermore, the detection element 2 is a photoelectric detection element or a capacitance detection element. The principles of these two types of detection yarns are mature technologies in this field, and therefore will not be elaborated further.

[0053] Furthermore, the detection component 4 includes a detection circuit board 41, which is also provided with a connector 42, and the connector 42 faces the open end 11. The connector 42 facilitates the rapid installation of multiple yarn sensors and subsequent replacement and maintenance. The circuit board can be configured with wiring and electronic components as needed.

[0054] Furthermore, the detection end 12 of the housing 1 is provided with a warning hole 16, and a warning light is installed inside the warning hole 16. The warning light is connected to the detection component 4. The detection component 4 controls the warning light. When a yarn breakage or fault is detected, an alarm is triggered in time through the warning light, which is generally a red warning light. During normal operation, a green light may be displayed, or no light may be displayed. However, when a fault occurs, an alarm is triggered through the red warning light.

[0055] Furthermore, at least one mounting hole 6 is provided on the mounting fixing piece 5. The housing 1 is fixedly installed through the mounting fixing hole 6. Since the mounting fixing piece 5 is located on the outside of the housing 1, it can achieve a limiting function during assembly.

[0056] Furthermore, the mounting and fixing plates 5 are arranged around the perimeter of the housing 1. If the detection end 12 is defined as the front end, then the open end 11 is the rear end, and the top, bottom, left, and right sides are the perimeter. The mounting and fixing holes 6 are then placed on the left and right sides to ensure stable installation.

[0057] Furthermore, the distance between the mounting fixing piece 5 and the open end 11 is 1-1.5 cm. The open end 11 is inserted into the channel and fixed by the mounting fixing piece 5.

[0058] By shortening the mounting section of the yarn sensor while keeping the mounting groove unchanged, the internal space is increased. The connector 42 is located within the groove, facilitating subsequent wiring. The increased internal space also makes cleaning of internal oil stains easier, preventing interference with the yarn sensor's operation. In case of a malfunction, the yarn sensor can be removed, the wire at connector 42 disconnected, and the quick-installation assembly 3 unscrewed to remove the internal detection assembly 4. After replacing it with a suitable circuit board, reassembly allows for repair, improving the efficiency of subsequent maintenance.

[0059] The yarn sensor of this application is assembled as follows: the housing is placed horizontally with the open end exposed; the detection circuit board and related electronic components are fabricated, and the detection element is connected to the detection circuit board at the same time; the assembly of the circuit board is inserted into the housing from the open end, while ensuring that the detection element and the detection notch are correspondingly set; the two are assembled by using quick positioning parts and detection positioning holes, and screws are installed.

[0060] In practical use, a channel is installed on the textile equipment, with connecting lines installed within it. An installation notch is provided on the outer side of the channel. The open end of the yarn sensor faces the installation notch, and the connecting lines are plugged into the connector. The open end is then inserted into the installation notch and secured to the channel using screws and mounting holes. A mounting bracket limits the movement of the yarn within the channel. Yarn enters through the detection notch, and the yarn is detected. When a yarn breakage occurs, an alarm light sounds, and the worker can then handle the broken yarn.

[0061] When the yarn sensor malfunctions, remove the screws from the mounting holes, disconnect the wiring from the connector, remove the faulty yarn sensor, and replace it with a new one. To repair the faulty yarn sensor, remove the quick-install assembly, remove the detection assembly, replace the circuit board, and then reassemble it.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
