Description

Technical Field

[0001] This utility model relates to the field of calendering machine technology, and in particular to a thickness detection device for a calendering machine. Background Technology

[0002] A calender consists of two or more rollers arranged according to the heating method. It can be divided into cold pressing and hot pressing. Cold pressing is suitable for materials that do not require heating, such as graphite film, graphite sheet, microwave absorbing materials, shielding materials, magnetic materials, non-ferrous metal materials, etc. It presses and stretches materials such as rubber, silicone, silicone rubber, phase change materials, PTFE or plastics into sheets of a certain thickness and surface shape at a certain temperature. When processing materials in a calender, a thickness detection function is required to detect the thickness of the material.

[0003] A search of the Chinese patent "A Copper Flat Strip Thickness Detection Device on a Rolling Mill" (publication number CN209214546U) reveals that this patent utilizes the reflection and reception principle of displacement sensor two to determine the distance between the displacement sensor two and the copper strip. The two displacement sensors two can be used for comparison to determine whether the copper flat strip is horizontal and adhered to the transparent substrate. If it is horizontally adhered, the indicator light will turn green, indicating that the position is correct, thus increasing the accuracy of the measurement. The device uses the adjustment of two sliders to make the roller surface horizontally press the copper flat strip against the transparent substrate, improving the detection effect of displacement sensors one and two. However, when detecting the thickness of the rolling mill, displacement sensors one and two are not accurate enough when detecting different materials, and are prone to deviation, making it inconvenient to effectively detect the material thickness and reducing the effectiveness of the device.

[0004] Therefore, a thickness detection device for a calender is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a thickness detection device for a calender to solve the above-mentioned problems, thereby improving the difficulty in effectively detecting the thickness of materials.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a thickness detection device for a calender, comprising a calender body, with two mounting brackets fixedly connected to one end of the calender body; a detection mechanism, which can accurately detect the thickness of materials on the calender, is disposed on the inner wall of the mounting brackets; wherein, the detection mechanism includes a thickness gauge slidably connected to one side of one of the mounting brackets, a mounting plate slidably connected to the inner wall of one of the mounting brackets, a fixing block slidably connected to the inner wall of the mounting plate, a probe mounted at the bottom end of the fixing block, one end of the probe communicating with the thickness gauge, the thickness gauge can measure the thickness of the material by emitting ultrasonic pulses through the probe, and the thickness of the material can be known by observing the thickness gauge; the mounting plate in one of the mounting brackets can move up and down to drive the probe to fit against the surface of the material, thereby detecting the thickness of the material on the calender.

[0007] Preferably, the detection mechanism includes an electric slide rail installed on one side of the inner wall of the mounting plate, and one side of the fixing block is installed on the slider on the outer wall of the electric slide rail by fixing bolts. The electric slide rail can drive the fixing block to one side to adjust the detection position of the probe, thereby improving the detection effect of the device.

[0008] Preferably, connecting frames are fixedly connected to both sides of the top of the mounting plate. Two electric push rods are installed at the top of one of the mounting frames. One end of the electric push rod passes through the mounting frame and is fixedly connected to the connecting frame. The two electric push rods can drive the mounting plate to move up and down, which facilitates the detection of the thickness of the material.

[0009] Preferably, a calibration plate is fixedly connected to the inner wall of the calender body. The calibration plate is located at the bottom of the probe. After use, the probe can be calibrated by the calibration plate to maintain the detection accuracy of the probe.

[0010] Preferably, laser sensors are installed on the inner top wall of the other mounting bracket and the inner wall of the calender body. A display screen is installed on one side of the other mounting bracket. The display screen is connected to the two laser sensors. The two laser sensors can detect the thickness of the object by means of mutual beam.

[0011] Preferably, mounting blocks are fixedly connected to both sides of the top of the calender body, and a scraper is slidably connected between the two mounting blocks. The scraper can clean dust and impurities on the surface of the material, thereby improving the detection effect of the device.

[0012] Preferably, the inner wall of the mounting block is provided with two compression springs, and the scraper is disposed between the two compression springs. The scraper can slide up and down within the mounting block through the two compression springs, and its position can be adjusted according to the thickness of the material.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up a detection mechanism, a thickness gauge on one mounting bracket can detect the thickness of the material by emitting ultrasonic pulses through its probe. The thickness of the material can be viewed by observing the display screen on the thickness gauge. A laser sensor in another mounting bracket can detect the thickness of the material by exchanging beams with a laser sensor in the main body of the calender. The thickness of the material can be displayed on the screen. An electric push rod, in cooperation with the connecting bracket, can move the mounting plate up and down to make the probe fit with the material. The electric push rod can also move the probe in the fixed block to both sides to adjust the detection position of the probe. A calibration plate can calibrate the probe. This allows for accurate detection of the material thickness on the calender, improving the effectiveness of the device.

[0015] 2. By setting up a scraper and compression springs, when the thickness gauge and laser sensor detect the thickness of the material on the calender, the scraper can scrape off impurities and dust from the material. The two sides of the scraper, in conjunction with two compression springs, can move up and down according to the thickness of the material. One end of the scraper is inclined, which can clean impurities from the object and improve the detection accuracy of the detection device. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] In practical implementation: such as Figure 1-4 As shown, a thickness detection device for a calender includes a calender body 1, with two mounting brackets 2 fixedly connected to one end of the calender body 1; a detection mechanism 3, which can accurately detect the thickness of the material on the calender, is disposed on the inner wall of the mounting brackets 2; wherein, the detection mechanism 3 includes a thickness gauge 301 slidably connected to one side of one of the mounting brackets 2, a mounting plate 302 slidably connected to the inner wall of one of the mounting brackets 2, a fixing block 303 slidably connected to the inner wall of the mounting plate 302, a probe 304 installed at the bottom end of the fixing block 303, and one end of the probe 304 communicating with the thickness gauge 301.

[0023] When inspecting the material on the main body 1 of the calender, the PLC control system drives the transmission system to extrude the material through the rollers and transports the material to the bottom of the two mounting frames 2. The PLC control system drives the electric push rod 307 to move the probe 304 in the mounting plate 302 downward to fit against the material surface. The PLC control system then drives the thickness gauge 301 to control the probe 304 to emit ultrasonic pulses. When the ultrasonic pulse reaches the material interface, the pulse is reflected back to the probe 304. The thickness of the material is determined by the propagation time of the ultrasonic pulse in the material through precise measurement. Two laser sensors 309 are located at the upper and lower ends of the material, respectively. The PLC control system causes the two laser sensors 309 to emit lasers to measure the upper and lower surface positions of the material. The thickness of the object is calculated. The thickness gauge 301 and the laser sensors 309 work together to accurately detect the thickness of the material.

[0024] like Figure 2 and Figure 3As shown, the detection mechanism 3 includes an electric slide rail 305 installed on one side of the inner wall of the mounting plate 302. One side of the fixing block 303 is installed on the slider on the outer wall of the electric slide rail 305 by fixing bolts. Connecting brackets 306 are fixedly connected to both sides of the top of the mounting plate 302. Two electric push rods 307 are installed on the top of one of the mounting brackets 2. One end of the electric push rod 307 passes through the mounting bracket 2 and is fixedly connected to the connecting bracket 306. A calibration plate 308 is fixedly connected to the inner wall of the calender body 1. The calibration plate 308 is located at the bottom of the probe 304. Laser sensors 309 are installed on the inner top wall of the other mounting bracket 2 and the inner wall of the calender body 1. A display screen 310 is installed on one side of the other mounting bracket 2, displaying... The screen 310 is connected to two laser sensors 309. The electric push rod 307 drives the probe 304 in the mounting plate 302 to move up and down, so that it can fit into the material. When in use, the probe 304 can be moved to both sides by the fixed block 303 via the electric slide rail 305 to adjust the detection position of the thickness gauge 301. The thickness gauge 301 can detect the thickness of the material by emitting ultrasonic pulses through the probe 304. The calibration plate 308 can calibrate the accuracy of the probe 304. Then, the two laser sensors 309 emit lasers to measure the distance between the upper and lower surfaces of the material, so as to accurately detect the thickness of the material and improve the use effect of the detection device.

[0025] like Figure 4 As shown, mounting blocks 311 are fixedly connected to both sides of the top of the calender body 1. A scraper 312 is slidably connected between the two mounting blocks 311. Two compression springs 313 are provided on the inner wall of the mounting blocks 311. The scraper 312 is located between the two compression springs 313. When detecting the thickness of the material, the material passes through the scraper 312 and can squeeze one side of the bottom of the scraper 312, causing it to move upward and squeeze one of the compression springs 313. The compression spring 313 can apply moving pressure to the scraper 312 so that it can clean the dust on the material, which can improve the detection accuracy of the detection device.

[0026] In use, the calender body 1 conveys the material to two mounting frames 2. The electric push rod 307, driven by the PLC controller on the calender, cooperates with the connecting frame 306 to move the mounting plate 302 downwards, bringing the probe 304 into contact with the material. When the thickness gauge 301 is operated by the PLC controller, the probe 304 emits ultrasonic pulses to detect the thickness of the material. The electric push rod 307 moves the mounting plate 302 upwards. The electric slide rail 305, driven by the PLC controller, moves the probe 304 within the fixed block 303 to both sides, adjusting the detection position of the probe 304. Two laser sensors 309, controlled by the PLC controller, emit lasers to detect the upper and lower surfaces of the material, measuring the distance between them. When the material comes off the calender roll, it contacts the scraper 312, removing dust. The scraper 312 can move upwards according to the material thickness, compressing one of the compression springs 313 and adjusting its position.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
