Description

Technical Field

[0001] The present invention relates to the technical field of processing of magnesium-steel fire-resistant composite air ducts, and more specifically, to an automatic adjustment device for processing parameters of a magnesium-steel fire-resistant composite air duct. Background Art

[0002] A magnesium-steel fire-resistant composite air duct is a ventilation duct composed of a magnesium material and a steel material. It has good fire resistance, corrosion resistance and mechanical strength, and is widely used in fields such as building ventilation and air-conditioning systems. A magnesium-steel fire-resistant composite air duct usually consists of an outer magnesium material and an inner steel material. The magnesium material has high fire resistance and heat insulation performance, and can effectively prevent the spread of fire and heat transfer. The steel material provides good mechanical strength and stability, ensuring the structural strength and service life of the air duct. The processing of a magnesium-steel fire-resistant composite air duct mainly includes the following links: Material preparation: Prepare raw materials such as magnesium materials and steel materials, and conduct inspection and pretreatment. Plate processing: Process the magnesium material and the steel material into the required plate size and shape. This may include processes such as cutting, bending, stamping, etc. Composite process: Combine the magnesium material and the steel material through a specific composite process to form a composite plate. Common composite processes include gluing, welding, mechanical connection, etc. Air duct production: Process the composite plate into the shape of an air duct, and conduct splicing, sealing and other treatments. This may include processes such as cutting, bending, welding, riveting, etc. Surface treatment: Conduct surface treatment on the air duct, such as spraying, galvanizing, etc., to improve its corrosion resistance and aesthetics. Among them, in the processing link, it is often necessary to cut the composite plate. After cutting it into a specified size, multiple composite plates can be spliced into an air duct. Therefore, its cutting device is one of the important components in the processing of magnesium-steel fire-resistant composite air ducts.

[0003] Existing cutting devices for the production and processing of magnesium-steel fire-resistant composite air ducts often lack a certain automatic adjustment function. This results in the need for personnel to manually adjust the distance between its two guide plates according to the size of the composite plate every time when cutting composite plates of various sizes, so as to achieve the purpose of guiding the cutting of the composite plate. However, such back-and-forth manual adjustment undoubtedly causes many inconveniences in actual use. And when cutting composite plates of various widths and thicknesses, usually a cutting motor is used in cooperation with a cutting plate for cutting, and its cutting speed is relatively fixed. This leads to the fact that when cutting some thick and difficult-to-cut composite plates, the cutting tool is often worn out due to too fast cutting speed, and it is also very likely to cause the cutting quality of the composite plate, causing many inconveniences in actual use;

[0004] Moreover, when cutting and processing relatively thick composite boards, the cutting area often lacks a certain degree of stability, which easily leads to the phenomenon of composite board deviation due to the vibration generated during cutting, thereby bringing great trouble to the cutting accuracy. Secondly, it is also difficult to collect the generated waste chips better at the same time, which will undoubtedly also bring certain trouble to the actual use.

[0005] In view of this, we propose an automatic processing parameter adjustment device for magnesium steel refractory composite air ducts. Summary of the Invention

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present invention are as follows: When in use, the composite plates required for the magnesium steel refractory composite air duct are first placed on the conveying device in sequence, and at this time, the conveying device will drive the composite plates to move and convey. During the conveying process, the infrared width measuring light curtains on both sides thereof will accurately detect the width of the composite plates, and the detected data will be quickly transmitted to the external console. The console can then control multiple electric push rods I to drive two guiding and limiting components respectively, and perform precise adjustment according to the width of the composite plates. In this way, more stable guiding and limiting can be carried out for the composite plates. During the process of guiding and limiting the composite plates by using multiple guiding and limiting components, multiple movable frames will be adaptively adjusted due to the action of springs, and the movable rollers I at the bottom of the movable frames will perform rolling cooperation, capable of smoothly towing the composite plates at the bottom of the movable frames. At the same time, multiple displacement sensors will be pressed due to the passing of the composite plates, and then accurately judge the thickness of the composite plates according to the displacement distance of the pressing. After that, the data will also be uploaded to the external console. By using the external console, it is possible to control the electric push rod II to drive the movable limiting plate to descend according to these data, so as to perform limiting and guiding on the top of the composite plates. While performing limiting and guiding on the top of the composite plates, the length measuring sensor can better detect according to the required cutting length. When the length reaches the requirement, it can be cut by the cutting component. By making better use of the functions of multiple sensors, it is possible to automatically adjust the guiding and limiting according to the parameters of the composite plates, and the measured width and thickness can also be uploaded to the external console. The console can also better control the cutting speed of the cutting component according to these parameters, effectively reducing the problems of excessive wear of the cutting tool caused by too fast cutting speed and affecting the cutting quality;

[0019] Moreover, during cutting, the functions of multiple lead screw motors I can be utilized to drive two pressing boxes to move downward, and clamp and stabilize the position of the composite plate to be cut, which can greatly reduce the influence on the cutting of the composite plate. And during the process of multiple pressing boxes clamping and stabilizing the composite plate, the dust suction pump can be started to form negative pressure inside the multiple pressing boxes, so as to suck the waste chips generated by cutting through the action of multiple dust suction ports and transfer them into the collection box. Thus, while stabilizing the cutting position, it is more convenient for the collection of waste chips, significantly improving the stability of the cutting of the composite plate and the convenience of the subsequent collection of waste chips.

[0034] In some embodiments: The principle of the infrared width measurement light curtain 120 is to use the principle of light path occlusion between an infrared emitter and a receiver to measure the width of an object.

[0036] Specifically, the side walls of the plurality of stabilizing frames 150 are provided with connecting plates 151, and the plurality of connecting plates 151 are respectively sleeved on the circumferential outer walls of their respective screw rods. The front and rear outer walls of the fixed platform 100 are provided with guide grooves 140, and the two sides of the plurality of connecting plates 151 are respectively extended to the inside of the guide grooves 140, so as to facilitate the use of the screw motor 210 to drive the two downward pressure boxes 152 to stabilize the thickness of the composite plate according to the cutting position thereof.

[0040] In some embodiments: the displacement sensor 252 can use an eddy current displacement sensor. Based on the principle of electromagnetic induction, when alternating current is applied to the coil, an alternating magnetic field is generated, and eddy currents are induced in nearby conductive materials (such as metal surfaces). The change in the distance between the surface of the object being measured and the sensor will affect the intensity and phase of the eddy current. By analyzing the change in the eddy current signal, the distance between the two can be measured, and then the thickness of the object can be obtained. For example, the UK Zhenshang has the ZED23 series eddy current displacement sensor, which belongs to the prior art.

[0042] It should be noted that a through hole 231 matching the displacement sensor 252 is provided at the top of the fixed plate 230.

[0046] In some embodiments: The device can be powered by an external conventional power supply. The device can be controlled by a console. The console includes a central processor, a memory, an input-output interface, a display screen, an operation panel and a communication module through its structure. Its principle is data reception: The console receives data from devices such as the infrared width measurement light curtain 120, the displacement sensor 252, and the length measuring sensor 273 through the input-output interface. These data include parameters such as the width, thickness, and length of the composite board;

[0047] Data analysis and processing: The central processor analyzes and processes the received data. According to the preset algorithms and logics, it judges whether the size of the composite board meets the requirements and calculates the parameters that need to be adjusted, such as the position of the guiding and limiting component, the height of the moving limit plate 271, the speed of the cutting assembly, etc.;

[0048] Control instruction generation: According to the results of the analysis and processing, the central processor generates corresponding control instructions. These instructions are sent to execution mechanisms such as multiple electric push rods and cutting assemblies through the input-output interface to realize the guiding, limiting and cutting control of the composite board;

The above are all prior arts.

[0051] In addition, the circuits, electronic components, and modules involved in the present invention are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present invention does not involve improvements to the internal structure and method either.

[0052] Working principle: When in use, the composite boards required for the magnesium-steel refractory composite air duct are first placed on the conveying device 110 in sequence. At this time, the conveying device 110 will drive the composite boards to move and convey. During the conveying process, the infrared width measurement light curtains 120 on both sides will accurately detect the width of the composite boards. The detected data will be quickly transmitted to the external control console, and the console can immediately control multiple electric push rods 210 to drive two guiding and limiting components respectively, and precisely adjust according to the width of the composite boards. In this way, more stable guiding and limiting can be carried out for the composite boards. During the process of guiding and limiting the composite boards by using multiple guiding and limiting components, its multiple movable frames 250 will be adaptively adjusted due to the action of the springs 260. The movable rollers 251 at the bottom of the movable frames 250 will perform rolling cooperation, and can smoothly tow the composite boards at the bottom of the movable frames 250. At the same time, multiple displacement sensors 252 will be pressed due to the passing of the composite boards, and then accurately judge the thickness of the composite boards according to the displacement distance of the pressing. After that, the data will also be uploaded to the external control console. By using the external control console, it can control the electric push rod 270 to drive the movable limiting plate 271 to descend according to these data, so as to limit and guide the top of the composite boards. While guiding and limiting the top of the composite boards, its length measurement sensor 273 can better detect according to the required cutting length. When the length reaches the requirement, it can be cut by the cutting component. By making better use of the functions of multiple sensors, the guiding and limiting can be automatically adjusted according to the parameters of the composite boards, and the measured width and thickness can also be uploaded to the external control console. The console can also better control the cutting speed of the cutting component according to these parameters, effectively reducing the problems of excessive wear of the cutting tool 325 caused by too fast cutting speed and affecting its cutting quality. Moreover, during cutting, the functions of multiple lead screw motors 130 can be used to drive two pressing boxes 152 to move downward, and clamp and stabilize the position of the composite board to be cut. This can greatly reduce the impact on the cutting of the composite board. And during the process of multiple pressing boxes 152 clamping and stabilizing the composite board, the dust suction pump 420 can be started to form a negative pressure inside the multiple pressing boxes 152, so as to suck the waste chips generated by cutting through the multiple dust suction ports 153 and transfer them to the inside of the collection box 430. Thus, while stabilizing the cutting position, it is more convenient for the collection of waste chips, significantly improving the stability of the cutting of the composite board and the convenience of the subsequent collection of waste chips.
