Description

Technical Field

[0002] The shortage warning device used in the screw feeder is to ensure a continuous and seamless supply of screws in the supply chain to avoid production line stagnation or reduced output due to shortage of materials. The shortage warning device includes a capacitive sensor, which can detect the presence or absence of an object. The principle is to judge the presence or absence of a screw based on the effect of the object on the electric field of the capacitive sensor. Once the capacitive sensor detects the lack of an object inside the feeder, it will send a shortage signal.

[0003] The sensor is a capacitive sensor. The traditional sensor has a single internal material and weak corrosion resistance and pressure resistance. The sensor will be quickly damaged when it comes into contact with corrosive media and cannot provide accurate warning information. In addition, the sensor is limited to the inside of the feeder body through the installation of the positioning plate. The installation method of the two is relatively cumbersome, which reduces the ease of use of the shortage warning device. Therefore, it is particularly important to design a shortage warning device for a screw feeder. Utility Model Content

[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4As shown, one end of the two screw rods 11 is threadedly sleeved with a nut 12, and one side of the extension plate 14 is fixedly connected to one side of the bottom plate 13. The utility model is a material shortage warning device for a screw feeder. By setting the bottom plate 13, the support shaft 15, the arc plate 16 and the clamping strip 18, after the screw rod 11 is interlaced with the positioning plate 4, the extension plate 14 will also penetrate into the interior of the positioning plate 4, and the support shaft 15 is rotated to drive the arc plate 16 to rotate at the same time, so that the arc plate 16 and the positioning plate 4 are parallel to each other.

[0026] Working principle: The material shortage warning device used in the screw feeder is to ensure a continuous and seamless supply of screws in the supply chain to avoid production line stagnation and output reduction due to material shortage. The material shortage warning device includes a capacitive sensor. The capacitive sensor can detect the presence and absence of an object. The principle is to judge the presence or absence of a screw based on the influence of the object on the electric field of the capacitive sensor. Once the capacitive sensor detects the lack of an object inside the feeder, it will send out a material shortage signal. Sensor 1 is a capacitive sensor. The traditional sensor 1 has a single internal material and weak corrosion resistance and pressure resistance. Sensor 1 will be quickly damaged when it comes into contact with corrosive media and cannot provide accurate warning information. In addition, sensor 1 is limited to the inside of the feeder body 2 by installation with the positioning plate 4. The installation method of the two is relatively cumbersome, which reduces the ease of use of the material shortage warning device. For this reason, since the corrosion-resistant layer 8 is made of copper-nickel alloy, it has good corrosion resistance and mechanical strength. , the corrosion resistance of the sensor 1 is improved, the sound insulation layer 9 is made of synthetic rubber, which has good sound insulation and shockproof performance, and has a sound insulation effect on the sensor 1. The pressure-resistant layer 10 is made of carbon fiber, which improves the deformation resistance of the sensor 1. After one side of the sensor 1 is fitted with the surface of the positioning plate 4, the two screws 11 penetrate into the interior of the positioning plate 4, and the two nuts 12 are used to form a threaded sleeve on one end of the screw 11, so that the sensor 1 and the positioning plate 4 can be limited and fixed, which improves the firmness of the installation of the shortage warning device. After the screw 11 is interlaced with the positioning plate 4, the extension plate 14 will also penetrate into the interior of the positioning plate 4, and the support shaft 15 is rotated to drive the arc plate 16 to rotate at the same time, so that the arc plate 16 and the positioning plate 4 are parallel to each other, and then one end of the card strip 18 is embedded in the interior of the card slot 17, and the two are connected by card engagement, so that the sensor 1 and the positioning plate 4 can be limited, and the stability of the installation of the sensor 1 and the positioning plate 4 is further enhanced.
