Abstract
Description
Technical Field
[0001] This utility model belongs to the field of testing equipment technology, specifically relating to a high-temperature inductive edge-tracking sensing device and a strip winding production line. Background Technology
[0002] In galvanized metal strip products, hot-dip galvanized steel strips pass through a zinc pot containing molten zinc and are then passed above the zinc pot by a pair of air knives. The high-pressure gas sprayed from the air knives wipes away excess molten zinc from the surface of the strip. The thickness and uniformity of the coating on hot-dip galvanized steel strips are important indicators for evaluating the quality of galvanized sheets.
[0003] Over-galvanizing at the edges results in a coating thickness at the strip edges that is greater than at the center, severely affecting the uniformity of the coating's lateral distribution and negatively impacting coating quality and service life. The formation of this defect is related to the viscosity of the molten zinc, surface tension, and the lateral dispersion of airflow at the strip edges. Under the influence of these factors, the scraping resistance of the coating at the strip edges increases, and the surface pressure of the strip decreases, easily leading to the defect of an excessively thick zinc layer at the edges of the galvanized sheet. Therefore, a sensing device capable of detecting signals at the edges of galvanized sheets is needed. Utility Model Content

[0025] The present invention will now be described in further clear and complete detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0027] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0028] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.
[0029] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0030] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
[0031] This utility model discloses a high-temperature inductive edge-tracking sensing device, such as... Figure 1-3 As shown, the system includes a first edge-following sensor and a second edge-following sensor symmetrically arranged on the left and right sides of the strip 1. Specifically, the first edge-following sensor and the second edge-following sensor are respectively mounted on the left and right sides of the strip 1 via fixed brackets. Both the first edge-following sensor and the second edge-following sensor include a high-temperature coil 2 and a signal processing module 3 connected to the high-temperature coil 2. The high-temperature coil 2 and the signal processing module 3 are connected via a high-temperature connecting wire. The high-temperature coil 2 includes a transmitting coil 21 and a receiving coil 22. A space is formed between the transmitting coil 21 and the receiving coil 22 for the strip 1 to pass through. Specifically, the high-temperature coil 2 has an inverted "U" shaped structure design. The transmitting coil 21 and the receiving coil 22 are symmetrically arranged and are located on the upper and lower sides of the strip 1, respectively.
[0032] When using the high-temperature inductive edge-following sensing device of this utility model, a high-frequency sine wave drives the transmitting coil 21. The two sides of the strip 1 pass through the transmitting coil 21 and receiving coil 22 of the first and second edge-following sensors, respectively. The receiving coil 22 senses the edge position of the strip 1 in real time. The signal processing module 3 performs digital processing to obtain the edge position signal of the strip 1, and outputs it through a 4-20mA current signal.
[0033] This utility model also provides a strip winding production line, including the above-mentioned high-temperature inductive edge-tracing sensing device and winding controller. The winding controller is used to receive signals from the signal processing module 3 and control the movement of the hydraulic cylinder according to the received signals to realize strip winding.
[0034] In summary, the high-temperature inductive edge-tracking sensing device and strip winding production line provided by this utility model have a simple structure and are easy to operate. They realize the function of detecting signals on both sides of metal strips and have the advantages of high temperature resistance, pollution resistance, maintenance-free operation, anti-interference, and anti-static properties. They have great market value and are worthy of widespread promotion and application.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
