Description

Technical Field

[0001] The invention relates to the technical field of composite material pultrusion, and in particular to a composite material pultrusion yarn break alarm device and a control method. Background Art

[0002] The composite material pultrusion process is a composite material molding process that applies traction to fibers impregnated with resin glue, allowing them to pass through a molding mold with a certain cross-sectional shape and solidify in the mold cavity. The fibers of the molded products are arranged unidirectionally and can be fully straightened under tension. The performance of the fibers can be fully utilized. The fiber content is crucial to the performance of the pultruded products. However, in the production process of pultruded products, the yarn may break due to problems such as wool yarn and yarn ends, thus affecting the performance of the product.

[0003] The traditional detection method is to detect yarn breakage through manual inspection or through a complex optical recognition system. Manual inspection has the problems of low detection efficiency, high missed detection rate, and high labor intensity. In addition, the yarn rack for installing fiber yarn is generally more than 2 meters high. Manual inspection also has certain safety hazards. The traditional optical recognition system detection is easily disturbed by strong light, has low accuracy, complex structure, and high maintenance cost. Summary of the invention

[0004] In view of this, the present invention aims to propose a composite material pultrusion yarn breakage alarm device and a control method to solve the problems in the prior art of low efficiency, high missed detection rate, high labor intensity, and optical recognition system detection is easily disturbed by strong light, with low accuracy, complex structure and high maintenance cost.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] A composite material pultrusion yarn break alarm device, the composite material pultrusion yarn break alarm device, comprises a fixed frame, the fixed frame is provided with a yarn dividing plate, a signal sensor, a signal processor and an alarm, the signal processor is electrically connected to the signal sensor and the alarm respectively, the yarn dividing plate is provided with a yarn threading hole, a signal sub is provided on the front side of the yarn threading hole, the yarn passes through the signal sub and the yarn threading hole in sequence, after the yarn breaks, the signal sub falls onto the signal sensor, the signal sensor and the signal sub cooperate to detect the yarn breakage information, and send the yarn breakage information to the signal processor, and the signal processor controls the alarm to send the alarm information to the outside according to the yarn breakage information.

[0007] The composite material pultrusion yarn breakage alarm device in the present application detects yarn breakage information by cooperating with a signal sub-signal and a signal sensor. The signal processor controls the alarm to send alarm information to the outside world according to the yarn breakage information. This alarm device not only has a simple structure, high working stability, and low maintenance cost, but also can greatly improve the efficiency of yarn breakage detection.

[0008] The signal sub comprises a hook and an indicator plate, wherein the hook is arranged above the indicator plate, the hook is used to install the signal sub on the yarn, and the indicator plate is used to cooperate with the signal sensor to detect yarn breakage information.

[0009] The use of a hook makes it easy to install the signal sub on the yarn, and this arrangement has a simple structure and is convenient for production and manufacturing.

[0010] An identification chip is arranged inside the indicator plate, and the identification chip is used to cooperate with a signal sensor to detect yarn breakage information.

[0011] By setting an identification chip inside the sign, the signal sensor can detect the specific location of the broken yarn, which is convenient for personnel to quickly repair and improve work efficiency.

[0012] The indicator board is provided with a digital outer code, and the yarn separation plate below the yarn threading hole is provided with a digital inner code, and the digital outer code and the digital inner code correspond to each other one by one.

[0013] This arrangement makes it easy to install signal sub-devices and improves work efficiency.

[0014] A baffle is arranged on the front side of the yarn separation plate, and the baffle is used to prevent the signal element from sliding in a direction away from the yarn separation plate.

[0015] This structure can limit the position of the signal element to just above the signal sensor, thereby preventing the signal element from falling outside the signal sensor and affecting the yarn break detection result.

[0016] The signal sensor includes a receiving plate and a containing plate connected together, the containing plate is fixed on the ground, one end of the receiving plate is connected to the containing plate, and the other end is inclined away from the ground, and a pressure sensor and / or a resistance sensor and / or a capacitance sensor is arranged inside the signal sensor.

[0017] The receiving plate is parallel to the ground, and the receiving plate forms an angle α° with the ground. This arrangement makes it easy for the signal sensor to receive the signal. At the same time, arranging a pressure sensor and / or a resistance sensor and / or a capacitance sensor inside the signal sensor can also improve the accuracy of yarn break detection.

[0018] Preferably, 30°<α<60°.

The signal processor includes a power supply and an industrial control mainboard. The power supply is used to supply power to the industrial control mainboard, the signal sensor and the alarm. The industrial control mainboard is used to receive the signal sent by the signal sensor and control the alarm to send an alarm signal to the outside world.

[0022] Specifically, this arrangement can expand the propagation range of the alarm signal, allowing users to obtain alarm information in a timely manner.

[0023] The signal processor is provided with a start button, a stop button, a reset button and a display screen. The start button is used to start the alarm device, the stop button is used to turn off the alarm device, the reset button is used to restart the alarm device after the broken yarn is repaired, and the display screen is used to display the detection information of the alarm device.

[0024] This setting can not only check the specific yarn break position through the display screen to improve work efficiency, but also avoid affecting normal production due to yarn breakage.

[0025] The present invention also provides a control method based on the composite material pultrusion yarn break alarm device, comprising the steps of:

[0026] S1: Activate the alarm device through the signal processor;

[0027] S2: When the yarn breaks, the signal element loses the support of the yarn and falls downward into the signal sensor, and the signal sensor sends a yarn break signal to the signal processor;

[0029] S4: After the operator connects the broken yarn, the composite material pultrusion broken yarn alarm device is restarted through the signal processor.

[0030] This control method not only has a simple detection method and high detection efficiency, but is also not easily affected by external environmental conditions, has high stability and a low missed detection rate. It can not only enable users to understand yarn breakage information in a timely manner, but also avoid production failures caused by yarn breakage in pultrusion equipment, thereby improving production reliability.
