Description

Technical Field

[0001] This utility model belongs to the field of yarn breakage detection technology for ribbon weaving machines, and specifically relates to a yarn breakage detection alarm device for ribbon weaving machines. Background Technology

[0002] The yarn breakage detection alarm device for ribbon weaving machines is an automated device installed on the ribbon weaving machine. It uses multiple principles such as photoelectric, capacitance and mechanical contact to monitor the state of the yarn in real time during the ribbon weaving process. When a yarn breakage is detected, it can quickly issue an audible and visual alarm signal to remind the operator to deal with it in time. At the same time, it can also process signals and record relevant data through signal processing circuits and controllers to avoid ribbon quality problems and equipment damage caused by yarn breakage, thereby improving production efficiency and product quality.

[0003] However, although the photoelectric yarn breakage detection alarm device has a certain degree of resistance to environmental interference, its detection accuracy will still be significantly affected when faced with strong direct light or drastic fluctuations in the light environment. When the workshop lighting equipment suddenly malfunctions and produces flickering or dimming light changes, such light source interference will directly affect the signal receiving end of the photoelectric sensor, causing abnormal fluctuations in the light intensity signal it receives. This abnormal light signal will be misjudged by the sensor as a change in the light path caused by yarn breakage, thereby triggering the alarm mechanism and causing the equipment to frequently alarm falsely. This not only disrupts the normal production order, but also increases the workload of operators in troubleshooting and reduces production efficiency.

[0004] To address the aforementioned issues, this application proposes a yarn breakage detection alarm device for a ribbon weaving machine. Utility Model Content

[0009] As a preferred technical solution of this utility model, a protective shell is fixedly connected to the outer surface of each of the fixed seats, and each of the protective shells is sleeved on the outside of the brake motor.

[0010] As a preferred embodiment of this utility model, two limiting rings are fixedly connected to the outer surface of the rotating rod, and the side of each set of limiting rings that is close to each other is in contact with the side of each set of connecting frames that is far apart from each other.

[0011] As a preferred embodiment of this utility model, each of the two electric push rods has a fixed block fixedly connected to one end of each other, and the bottom surface of each fixed block is fixedly connected to the upper surface of the groove plate.

[0012] As a preferred embodiment of this utility model, the bottom surface of the support plate is fixedly connected to two mounting rings, and the bottom surface of each mounting ring is fixedly connected to the upper surface of the lighting lamp.

[0013] As a preferred embodiment of this utility model, two fixing pins are provided above the support plate, and the top end of each fixing pin passes through the fixing frame and extends to the top of the fixing frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a support plate and a fixed frame in conjunction with a yarn breakage detection alarm device, the device can detect and alarm on yarn breakage in the webbing. Simultaneously, the controller can be used to turn the device on and off or adjust it in both directions. The forward or reverse rotation of the brake motor drives the rotating rod to rotate on the connecting frame. The rotation of the rotating rod also adjusts the position of the groove plate and sliding plate. The extension and retraction of the electric push rod allows the sliding plate to slide within the groove plate. This allows the light at the detection position below the yarn breakage detection alarm device to be adjusted and blocked as needed. The lighting provides a stable illumination environment for the detection position of the yarn breakage detection alarm device, thereby reducing false alarms and further improving the stability of the device.

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.

[0023] Example

[0024] Please see Figure 1-5 This utility model provides the following technical solution: a yarn breakage detection alarm device for a weaving machine, including a support plate 1, a fixed frame 11 fixedly connected to the upper surface of the support plate 1, a yarn breakage detection alarm device 15 fixedly connected to the bottom surface of the support plate 1, groove plates 2 provided on the front and back of the support plate 1, a sliding plate 4 slidably connected inside each groove plate 2, an electric push rod 3 provided above each groove plate 2, the bottom surface of the telescopic end of each electric push rod 3 fixedly connected to the upper surface of the sliding plate 4, a connecting frame 5 fixedly connected to the front and back of each groove plate 2, the side of each set of connecting frames 5 close to each other fixedly connected to the two sides of the support plate 1, a rotating rod 12 rotatably connected to the inner wall of each set of connecting frames 5, the side of the two groove plates 2 close to each other fixedly connected to the outer surface of the rotating rod 12, two brake motors 7 provided on the left side of the support plate 1, the power output end of each brake motor 7 fixedly connected to the left end of the rotating rod 12, two lighting lamps 14 provided below the support plate 1, and a controller 9 provided above the support plate 1;

[0025] In this embodiment, the yarn breakage detection alarm device 15 detects yarn breakage through a photoelectric sensor. The sensor has two ends: a transmitter and a receiver. When the yarn is normal, it blocks or reflects light, and the receiver receives a stable light signal. When the yarn breaks, the light path changes, and the light signal parameters change. The sensor converts the light signal into an electrical signal and transmits it to the control system. Once the system determines that the yarn is broken, it immediately activates an audible and visual alarm to prompt the operator to handle the situation.

[0026] Specifically, the bottom surface of the controller 9 is fixedly connected to the connecting plate 10, and the bottom surface of the connecting plate 10 is fixedly connected to the upper surface of the support plate 1. In this embodiment, the controller 9 can be fixed to the support plate 1 through the connecting plate 10. At the same time, the controller 9 refers to the master control device that controls the starting, speed regulation, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence.

[0027] Specifically, each of the two brake motors 7 has a fixed base 6 fixedly connected to one side of each other. The right side of each fixed base 6 is fixedly connected to the left side of the support plate 1. In this embodiment, the brake motor 7 can be fixed to the support plate 1 through the fixed base 6. At the same time, the brake motor 7, also known as the brake motor, is a special motor that integrates an electromagnetic braking device on the basis of an ordinary motor, which can achieve fast and accurate braking and positioning.

[0028] Specifically, a protective shell 18 is fixedly connected to the outer surface of each fixed base 6. Each protective shell 18 is sleeved on the outside of the brake motor 7. In this embodiment, the brake motor 7 can be protected inside by the protective shell 18, and the brake motor 7 can be cooled by the openings of the protective shell 18 itself.

[0029] Specifically, two limiting rings 8 are fixedly connected to the outer surface of the rotating rod 12. The side of each set of limiting rings 8 that is close to each other is in contact with the side of each set of connecting frames 5 that is far from each other. In this embodiment, the limiting rings 8 can be fixed to the rotating rod 12 and in contact with the limiting rings 8, thereby limiting the rotating rod 12.

[0030] Specifically, each of the two electric push rods 3 has a fixed block 13 fixedly connected to one end of each other. The bottom surface of each fixed block 13 is fixedly connected to the upper surface of the slot plate 2. In this embodiment, the electric push rod 3 can be fixed to the slot plate 2 by the fixed block 13, and the electric push rod 3 can be stably extended and retracted.

[0031] Specifically, two mounting rings 16 are fixedly connected to the bottom surface of the support plate 1. The bottom surface of each mounting ring 16 is fixedly connected to the upper surface of the lighting lamp 14. In this embodiment, the lighting lamp 14 can be fixed to the support plate 1 through the mounting rings 16. At the same time, the lighting lamp 14 effectively assists the detection device in accurately identifying the yarn status by providing a stable and suitable lighting environment, avoiding misjudgment or missed judgment due to light problems.

[0032] Specifically, two fixing pins 17 are provided on the upper part of the support plate 1. The top end of each fixing pin 17 passes through the fixing frame 11 and extends to the top of the fixing frame 11. In this embodiment, the fixing pins 17 can penetrate the fixing frame 11 and fix it in a suitable position, thereby fixing the fixing frame 11.

[0033] The working principle and usage process of this utility model are as follows: First, connect the electric push rod 3, brake motor 7, lighting lamp 14, yarn breakage detection alarm device 15, and controller 9 to the power supply. Simultaneously, connect the electric push rod 3 and brake motor 7 to the controller 9 via wires. Then, fix the fixing frame 11 to a suitable position using the fixing pin 17. Once the fixing frame 11 is fixed, it supports and fixes the support plate 1 and the yarn breakage detection alarm device 15. After the yarn breakage detection alarm device 15 is installed and adjusted, the controller 9 starts the brake motor 7 to rotate forward or reverse. The rotation of the brake motor 7 drives the rotating rod 12 to rotate within the connecting frame 5. Simultaneously, the rotation of the rotating rod 12... The angle between the trough plate 2 and the sliding plate 4 is adjusted according to the detection position of the yarn breakage detection alarm device 15 and the ambient lighting. The electric push rod 3 is then extended and retracted via the controller 9. Simultaneously, the extension and retraction of the electric push rod 3 causes the sliding plate 4 to extend and retract within the trough plate 2. The extension and retraction of the sliding plate 4, in conjunction with the trough plate 2, increases or decreases the light-blocking area, thereby blocking the light at the detection position of the yarn breakage detection alarm device 15. Then, the detection position of the yarn breakage detection alarm device 15 is provided with independent lighting by the lighting lamp 14, thereby improving the detection effect of the yarn breakage detection alarm device 15. After the adjustment is completed, the yarn breakage detection alarm device 15 is turned on to further reduce the frequent false alarms of the yarn breakage detection alarm device 15.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
