Technical Field

[0001] This invention relates to the field of gypsum board facing paper thickness detection technology, specifically to a gypsum board facing paper production paper thickness detection device. Background Technology

[0002] Gypsum board facing paper is a paper material used to protect the surface of gypsum board. It is usually a fireproof, moisture-proof, and mildew-proof material that can effectively protect the surface of gypsum board from the influence of the external environment. The main material of gypsum board facing paper is polyethylene fiber and other fire-resistant materials. Polyethylene fiber has good flexibility and wear resistance, which can effectively prevent the facing paper from being torn and damaged. It can also play a role in waterproofing and moisture-proofing. In the production and installation of gypsum board products, the proper selection and use of facing paper is of great significance for improving the quality and service life of gypsum board products.

[0003] In the production process of gypsum board facing paper, the commonly used method to detect the thickness is to detect the radius or diameter of the entire roll of facing paper and then divide it by the total amount of facing paper wound on the roll, or to use a micrometer to sample and detect multiple points on the facing paper. In the production of gypsum board facing paper, the existing detection process generally only uses a single detection method, which is prone to errors in the detection process.

[0017] In summary, the present invention has the following main beneficial effects:

[0018] 1. This invention uses two detection methods to perform dual detection of gypsum board facing paper, ensuring that the detection results are error-free. Furthermore, by utilizing the difference in diameter between the first and second hydraulic rods, the lower pressure plate only needs to move a small stroke to extend the second hydraulic plate a longer length. This allows the operator to more intuitively see the detection values ​​when observing the first pointer and the first scale plate, resulting in more accurate detection results and a more convenient detection process.

[0019] 2. This invention, by pulling the top rod to move when using the pressure detection mechanism, causes the gear to rotate, thereby preventing the friction head from contacting the abutment wheel and the rubber wheel. This causes the winding shaft to lose power and stop rotating, so that when the pressure plate and the support table hold the face paper, the winding shaft will not continue to wind the face paper. This allows the pressure detection mechanism to detect the thickness of the face paper at any time during the winding process.

[0020] 3. This invention drives the rotating shaft to rotate when the first pressure roller rotates, which in turn drives the sliding disk to rotate. The sliding disk then drives the counterweight to rotate, thereby utilizing centrifugal force to push the sliding disk, causing the first and second grinding discs to come into contact. This creates resistance to the first pressure roller during rotation, preventing it from rotating too fast. The first and second pressure rollers clamp the face paper, ensuring that the face paper remains taut throughout the winding process. This guarantees consistent tension during winding and prevents wrinkles caused by the face paper being loose during the testing mechanism, which could affect measurement accuracy.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of the present invention will now be described.

[0037] A device for detecting the thickness of paper used in the production of gypsum board facing paper, such as Figures 1 to 10As shown, it includes a base 1, a pressure detection mechanism 2 is fixedly connected to the top of the base 1, and a winding detection mechanism 3 located next to the pressure detection mechanism 2 is fixedly connected to the top of the base 1.

[0038] The winding detection mechanism 3 includes two sets of side frames 301, with a winding shaft 302 rotatably connected between the two sets of side frames 301. One end of the winding shaft 302 is fixedly connected to an abutment wheel 303. A transmission component 304 is provided on the side wall of one set of side frames 301. A motor 305 is fixedly connected to the side wall of the base 1. A rubber wheel 306 is fixedly connected to the output end of the motor 305. The transmission component 304 is located between the rubber wheel 306 and the abutment wheel 303. A lifting plate 307 is slidably connected to the side walls of the two sets of side frames 301. The bottom end of the lifting plate 307 overlaps the outer wall of the winding shaft 302. A set of second scale plates 308 is fixedly connected to the side wall of each set of side frames 301. The two ends of the lifting plate 307 pass through the openings on the two sets of second scale plates 308 respectively. Two sets of second pointers 309 are fixedly connected to each end of the lifting plate 307.

[0039] The pressure detection mechanism 2 includes a support platform 201, which is fixedly connected to the top of the base 1. A guide frame 202 is fixedly connected to the top of the base 1. A pressure plate 203 is slidably sleeved on the outer wall of the guide frame 202. Multiple sets of tension springs 204 are fixedly connected to the top of the pressure plate 203, and the tops of the tension springs 204 are fixedly connected to the bottom of the guide frame 202. Multiple sets of first hydraulic rods 205 are fixedly connected to the side wall of the pressure plate 203, and the bottoms of the multiple sets of first hydraulic rods 205 are fixedly connected to the top of the base 1. A second hydraulic rod 206 is fixedly connected to the side wall of a side frame 301. 06 is connected to the first hydraulic rod 205 through a pipe. The diameter of the second hydraulic rod 206 is smaller than that of the first hydraulic rod 205. A push rod 207 is fixedly connected to the end of the second hydraulic rod 206. The push rod 207 is slidably connected to the side wall of the transmission assembly 304. A first pointer 208 is fixedly connected to the top of the push rod 207. A first scale plate 209 is fixedly connected to the side wall of the transmission assembly 304. A return spring 210 is fixedly connected to the top of the push rod 207. The end of the return spring 210 is fixedly connected to the side wall of the transmission assembly 304. A rack 211 is fixedly connected to the bottom of the push rod 207.

[0040] After the face paper passes between the first pressure roller 402 and the second pressure roller 404, it passes through the support plate and the lower pressure plate 203, and is then fixed on the take-up shaft 302. The motor 305 drives the rubber wheel 306 to rotate, which in turn pushes the friction head 30411 to rotate. The friction head 30411 drives the rotating ring 30410 to rotate, which in turn pushes the other friction heads 30411 to rotate. This causes the friction head 30411 at the top to push the abutment wheel 303 to rotate, which in turn drives the take-up shaft 302 to rotate, thus winding the face paper. The face paper is continuously wound onto the winding shaft 302. The lifting plate 307 is pushed upward by the face paper. During the upward movement of the lifting plate 307, the second pointer 309 slides on the outer wall of the second scale plate 308, causing the second pointer 309 to point to different scales. When winding stops, the thickness of the face paper can be calculated by dividing the scale corresponding to the second pointer 309 by the total number of rolls. During the winding process, the top rod 207 is pulled, causing it to slide. During the sliding process, the top rod 207 stretches the second hydraulic rod 206, creating a vacuum inside the second hydraulic rod 206, which in turn causes multiple sets of first hydraulic... Hydraulic oil inside the pressure rod 205 is drawn into the second hydraulic rod 206. At this time, multiple sets of first hydraulic rods 205 retract, thereby pulling the lower pressure plate 203 downward and stretching the tension spring 204. Simultaneously, the push rod 207 drives the first pointer 208 to move and compresses the return spring 210. When the lower pressure plate 203 presses the protective paper onto the support platform 201, the pulling of the push rod 207 stops. Since the diameter of the first hydraulic rod 205 is larger than the diameter of the second hydraulic rod 206, and multiple sets of first hydraulic rods 205 are simultaneously connected to the second hydraulic rods 206, the first hydraulic rods 205 retract a relatively small distance, requiring the first hydraulic... The pressure rod 205 extends a relatively long distance, and the ratio of the length changes between the two is relatively large. Based on the scale on the first scale plate 209 corresponding to the first pointer 208 at this time, the detected thickness of the face paper can be directly obtained. Then, the top rod 207 is released, causing the return spring 210 to rebound and push the top rod 207 to reset. At this time, the top rod 207 pushes the first hydraulic rod 205 to retract, causing multiple sets of second hydraulic rods 206 to extend, thereby causing the lower pressure plate 203 to reset. Then, the two sets of data obtained in the above process are compared to obtain a more accurate face paper thickness, and the phenomenon of error caused by a single detection method is avoided.

[0041] Please refer to this carefully. Figure 3 , Figure 4 and Figure 5The transmission assembly 304 includes a fixed disk 3041, which is fixedly connected to the side wall of the side frame 301. Two sets of turntables 3042 are rotatably connected to the side wall of the fixed disk 3041. The two sets of turntables 3042 are coaxially fixedly connected together. Multiple sets of push rods 3043 are slidably connected between the two sets of turntables 3042. Multiple sets of pushing grooves 3044 are respectively opened on the side wall of each set of turntables 3042. One end of the push rod 3043 is fixedly connected to a slide rod 3045. Both ends of the slide rod 3045 extend into the pushing grooves 3044 on the two sets of turntables 3042. The other end of the slide rod 3045 is fixedly connected to a rotating head 3048. A rotating ring 30410 is rotatably connected to the side wall of the side frame 301. The inner wall of the rotating ring 30410 is slidably sleeved on the outer wall of multiple sets of rotating rods 3049. One end of each set of rotating rods 3049 extending outside the rotating ring 30410 is fixedly connected to... A set of friction heads 30411 is connected. Two sets of spring plates 30413 are fixedly connected to the side wall of the friction heads 30411. The ends of the spring plates 30413 are fixedly connected to the inner wall of the rotating ring 30410. The other end of the rotating rod 3049 slides against the outer wall of the rotating head 3048. A guide plate 3046 is fixedly connected to the side wall of the fixed disk 3041. Each set of push rods 3043 is slidably sleeved on the outer wall of a set of guide plates 3046. A cover plate 3047 is fixedly connected to the side wall of multiple sets of guide plates 3046. A gear 30412 extending to the outside of the cover plate 3047 is fixedly connected to the side wall of the rotating disk 3042. The gear 30412 meshes with the rack 211. A push rod 207 is slidably connected to the side wall of the cover plate 3047. One end of the return spring 210 is fixedly connected to the side wall of the cover plate 3047. A first scale plate 209 is fixedly connected to the side wall of the cover plate 3047.

[0042] During the above process, when the push rod 207 is reset under the push of the return spring 210, the push rod 207 drives the rack 211 to move, causing the rack 211 to drive the gear 30412 to rotate. During the rotation of the gear 30412, the two sets of turntables 3042 rotate. The turntables 3042 push the slide rod 3045 to move through the push groove 3044, causing the slide rod 3045 to push the push rod 3043 to slide on the outer wall of the guide plate 3046, thereby causing multiple sets of rotating heads 3048 to extend outward. During the outward extension of the rotating heads 3048, the rotating rod 3049 is pushed to slide inside the rotating ring 30410 and compress the spring plate 30413, causing the rotating rod 3049 to push and rub. The friction head 30411 extends outward, so that during rotation, it contacts the abutment wheel 303 and the rubber wheel 306. The motor 305 drives the rubber wheel 306 to rotate, which in turn pushes the friction head 30411. This causes the friction head 30411 to drive the rotating rod 3049, which in turn drives the rotating ring 30410 to rotate. This causes all the friction heads 30411 to rotate, resulting in the rotating ring 30410, multiple rotating rods 3049, and multiple sets of friction heads 30411 rotating continuously under the push of the rubber wheel 306. As the multiple sets of friction heads 30411 rotate continuously, the abutment wheel 303 rotates under the push of the friction head 30411. During the rotation of the abutment wheel 303, the winding shaft 302 is driven to rotate, thereby winding the face paper. During the rotation of the rotating rod 3049, multiple sets of rotating rods 3049 continuously slide from the side wall of one set of rotating heads 3048 to the side wall of another set of rotating heads 3048. The gap between two adjacent sets of rotating heads 3048 is less than the length of the contact part between the rotating rod 3049 and the rotating head 3048, so the rotating rod 3049 can smoothly slide from the side wall of one set of rotating heads 3048 to the side wall of another set of rotating heads 3048. When the push rod 207 is pulled, the push rod 207 slides in the opposite direction, causing the push rod 207 to drive the rack 211 to move in the opposite direction. At this time, the rack 211 pushes the gear 3 0412 rotates in the reverse direction, thereby driving the turntable 3042 to rotate in the reverse direction. During the reverse rotation of the turntable 3042, the turntable 3042 pushes the slide rod 3045 to slide in the reverse direction through the push groove 3044, causing multiple sets of slide rods 3045 to move closer to each other. At this time, the slide rod 3045 pulls the top rod 207, causing the top rod 207 to drive the rotating head 3048 to move closer to each other. At this time, the spring plate 30413 rebounds, causing the rotating rod 3049 to reset, thereby driving the friction head 30411 to reset, so that the friction head 30411 cannot contact the rubber wheel 306 and the abutment wheel 303, thereby preventing the power of the rubber wheel 306 from being transmitted to the take-up shaft 302, causing the take-up shaft 302 to stop rotating.

[0043] Please refer to this carefully. Figure 6 , Figure 7 and Figure 8A tensioning mechanism 4 is fixedly connected to the top of the base 1. The tensioning mechanism 4 includes two sets of fixed seats 401, which are fixedly connected to the top of the base 1. A first pressure roller 402 is rotatably connected between the two sets of fixed seats 401. A set of sliders 403 is slidably connected to the inner wall of each set of fixed seats 401. A second pressure roller 404 is rotatably connected between the two sets of sliders 403. A pressure spring 405 is fixedly connected to the bottom end of the slide rod 3045. The base 1 is fixedly connected to the inner wall of the fixed base 401. Two sets of reduction gear assemblies 406 are fixedly connected to the top of the base 1. The reduction gear assemblies 406 include an outer cover 4061, which is fixedly connected to the top of the base 1. A rotating shaft 4062 is rotatably connected to the inner wall of the outer cover 4061. The end of the rotating shaft 4062 is fixedly connected to one end of the first pressure roller 402. An abutment plate 4063 is fixedly sleeved on the outer wall of the rotating shaft 4062, and a sliding plate 4064 is slidably sleeved on the outer wall of the rotating shaft 4062. The sliding disk 4064 is located between the inner wall of the abutment disk 4063 and the outer cover 4061. Multiple sets of connecting strips 4065 are fixedly connected to the side wall of the sliding disk 4064. The connecting strips 4065 are slidably connected to the side wall of the abutment disk 4063. Multiple sets of notches that mate with the connecting strips 4065 are provided on the side of the sliding disk 4064 closest to the abutment disk 4063. A set of inclined grooves 4066 are slidably connected to the inner wall of each set of inclined grooves 4066. Block 4067, the counterweight block 4067 is a cylindrical metal block, multiple sets of first grinding discs 4068 are fixedly connected to the side of the sliding disk 4064 away from the abutment disk 4063, multiple sets of second grinding discs 4069 are fixedly connected to the inner wall of the outer cover 4061, and a separation spring 40610 is sleeved on the outer wall of the rotating shaft 4062. One end of the separation spring 40610 is fixedly connected to the side wall of the sliding disk 4064, and the other end of the separation spring 40610 is fixedly connected to the outer wall of the rotating shaft 4062.

[0044] The pressure spring 405 pushes the slider 403 upward, causing the slider 403 to drive the second pressure roller 404 upward. This causes the second pressure roller 404 and the first pressure roller 402 to tightly clamp the face paper. As the face paper is wound up, it drives the first and second pressure rollers 402 to rotate. The first pressure roller 402 drives the rotating shaft 4062 to rotate, which in turn drives the abutment plate 4063 to rotate. The abutment plate 4063, through the connecting strip 4065, drives the sliding plate 4064 to rotate. As the winding speed increases, the rotation speed of the first pressure roller 402 increases, which in turn drives the rotation speed of the rotating shaft 4062, ultimately increasing the rotation speed of the abutment plate 4063 and the sliding plate 4064. The faster the sliding plate 4064 rotates, the more it carries... The faster the movable counterweight 4067 rotates, the greater the centrifugal force it experiences. At this time, the counterweight 4067 slides outward along the inclined groove 4066, thereby pushing the sliding disk 4064 away from the abutment disk 4063. This causes the sliding disk 4064 to compress the separation spring 40610 and drive the first grinding plate 4068 to move closer to the second grinding plate 4069. The friction between the first grinding plate 4068 and the second grinding plate 4069 causes the sliding disk 4064 to experience resistance when rotating. Since the abutment disk 4063's rotating shaft 4062 and the first pressure roller 402 rotate coaxially, the first pressure roller 402 experiences rotational resistance, ensuring that the face paper remains taut during winding. This prevents inconsistent winding tightness and avoids wrinkles in the face paper.

[0045] In use, two detection methods are used to perform dual detection on the gypsum board facing paper to ensure that the detection results are error-free. Furthermore, by utilizing the difference in diameter between the first hydraulic rod 205 and the second hydraulic rod 206, the lower pressure plate 203 only needs to move a small stroke to extend the second hydraulic plate a longer length. This allows the operator to more intuitively see the detection values ​​when observing the first pointer 208 and the first scale plate 209, thus making the detection results more accurate and the detection process more convenient. All parts of this device not mentioned herein are the same as or can be implemented using existing technologies.
