[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, which 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 fireproof 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 reasonable selection and use of facing paper is of great significance to improving the quality and service life of gypsum board products.

[0021] After the face paper passes between the first pressure roller 402 and the second pressure roller 404, the face paper passes through the support plate and the lower pressure plate 203 bracket, and is then fixed on the reel 302. The motor 305 drives the rubber wheel 306 to rotate, so that the rubber wheel 306 pushes the friction head 30411 to rotate, and the friction head 30411 drives the rotating ring 30410 to rotate, so that the rotating ring 30410 drives the other friction heads 30411 to rotate, so that the friction head 30411 that rotates to the top drives the abutment wheel 303 to rotate, and the abutment wheel 303 drives the reel 302 to rotate, so that the reel 302 reels the face paper. The facial paper is continuously rolled up on the winding shaft 302, and the lifting plate 307 is pushed upward by the facial paper. During the upward movement of the lifting plate 307, the second pointer 309 is driven to slide on the outer wall of the second scale plate 308, so that the second pointer 309 points to different scales. When the rolling stops, the thickness of the facial paper can be calculated according to the scale corresponding to the second pointer 309 and then divided by the total number of rolls. During the rolling process, the push rod 207 is pulled to make the push rod 207 slide. During the sliding process, the push rod 207 stretches the second hydraulic rod 206, so that a vacuum is generated inside the second hydraulic rod 206, so that multiple groups of first hydraulic rods 206 are The hydraulic oil inside the pressing rod 205 is sucked into the second hydraulic rod 206. At this time, the multiple groups of first hydraulic rods 205 contract, thereby pulling the lower pressing plate 203 to slide downward and stretching the tension spring 204. At the same time, the push rod 207 drives the first pointer 208 to move and compresses the return spring 210. When the lower pressing plate 203 presses the face paper on the support 201, the push rod 207 is stopped. Since the diameter of the first hydraulic rod 205 is larger than that of the second hydraulic rod 206, and the multiple groups of first hydraulic rods 205 are connected to the second hydraulic rod 206 at the same time, the first hydraulic rod 205 contracts a smaller distance, which requires the first hydraulic rod 207 to move. The pressure rod 205 is extended for a longer distance, and the ratio of the length changes between the two is larger. According to the scale on the first scale plate 209 corresponding to the first pointer 208 at this time, the detected face paper thickness can be directly obtained, and then the push rod 207 is released to make the reset spring 210 rebound and push the push rod 207 to reset. At this time, the push rod 207 pushes the first hydraulic rod 205 to contract, so that the multiple groups of second hydraulic rods 206 are extended, thereby resetting the lower pressure plate 203. Then, the two groups of data obtained in the above process are compared to obtain a more accurate face paper thickness, and avoid the phenomenon of errors caused by a single detection method.

[0022] Please refer to Figure 3 , Figure 4 and Figure 5The transmission assembly 304 includes a fixed plate 3041, which is fixedly connected to the side wall of the side frame 301. The side wall of the fixed plate 3041 is rotatably connected to two groups of rotating disks 3042. The two groups of rotating disks 3042 are coaxially fixedly connected together. Multiple groups of push rods 3043 are slidably connected between the two groups of rotating disks 3042. The side walls of each group of rotating disks 3042 are respectively provided with multiple groups of pushing grooves 3044. One end of the push rod 3043 is fixedly connected to a sliding rod 3045. The two ends of the sliding rod 3045 extend to the inside of the pushing grooves 3044 on the two groups of rotating disks 3042 respectively. The other end of the sliding rod 3045 is fixedly connected to a rotating head 3048. The side wall of the side frame 301 is rotatably connected to a rotating ring 30410. The inner wall of the rotating ring 30410 is slidably sleeved on the outer wall of multiple groups of rotating rods 3049. One end of each group of rotating rods 3049 extending to the outside of the rotating ring 30410 is respectively fixedly connected A group of friction heads 30411 are connected, and two groups of spring sheets 30413 are fixedly connected to the side walls of the friction heads 30411. The ends of the spring sheets 30413 are fixedly connected to the inner wall of the rotating ring 30410. The other end of the rotating rod 3049 slides and fits on the outer wall of the rotating head 3048. The side walls of the fixed disk 3041 are fixedly connected to guide sheets 3046. Each group of push rods 3043 is slidably sleeved on the outer walls of a group of guide sheets 3046 respectively. The side walls of multiple groups of guide sheets 3046 are fixedly connected to cover plates 3047. The side walls of the rotating disk 3042 are fixedly connected to gears 30412 extending to the outside of the cover plates 3047. The gears 30412 are meshed with the rack 211. The side walls of the cover plates 3047 are slidably connected to the push rods 207. The side walls of the cover plates 3047 are fixedly connected to one end of the reset spring 210. The side walls of the cover plates 3047 are fixedly connected to the first scale plate 209.

[0023] In the above process, when the push rod 207 is reset under the push of the reset spring 210, the push rod 207 drives the rack 211 to move, so that the rack 211 drives the gear 30412 to rotate. During the rotation of the gear 30412, the two sets of rotating disks 3042 are driven to rotate. The rotating disk 3042 pushes the slide bar 3045 to move through the push groove 3044, so that the slide bar 3045 pushes the push rod 3043 to slide on the outer wall of the guide sheet 3046, so that the multiple sets of rotating heads 3048 extend outward. During the process of the rotating heads 3048 extending outward, the rotating rod 3049 is pushed to slide inside the rotating ring 30410, and the spring sheet 30413 is compressed, so that the rotating rod 3049 pushes the friction The head 30411 extends outward, so that the friction head 30411 has contacted the abutment wheel 303 and the rubber wheel 306 during the rotation process. The motor 305 drives the rubber wheel 306 to rotate, so that the rubber wheel 306 pushes the friction head 30411, so that the friction head 30411 drives the rotating rod 3049, and the rotating rod 3049 drives the rotating ring 30410 to rotate, so that all the friction heads 30411 rotate, so that the rotating ring 30410, the multiple groups of rotating rods 3049 and the multiple groups of friction heads 30411 rotate continuously under the push of the rubber wheel 306. As the multiple groups of friction heads 30411 rotate continuously, the abutment wheel 303 rotates under the push of the friction heads 30411. The rotation of the contact wheel 303 drives the reel 302 to rotate, thereby reeling the face paper. During the rotation of the rotating rod 3049, multiple groups of rotating rods 3049 continuously slide from the side wall of one group of rotating heads 3048 to the side wall of another group of rotating heads 3048. The gap between the two adjacent groups of rotating heads 3048 is smaller than the length of the contact portion between the rotating rod 3049 and the rotating head 3048. Therefore, the rotating rod 3049 can smoothly slide from the side wall of one group of rotating heads 3048 to the side wall of another group of rotating heads 3048. When the top rod 207 is pulled, the top rod 207 slides in the reverse direction, so that the top rod 207 drives the rack 211 to move in the reverse direction. At this time, the rack 211 pushes the gear 3 0412 rotates in the opposite direction, thereby driving the turntable 3042 to rotate in the opposite direction. During the process of the turntable 3042 rotating in the opposite direction, the turntable 3042 pushes the sliding rod 3045 to slide in the opposite direction through the pushing groove 3044, so that the multiple groups of sliding rods 3045 are close to each other. At this time, the sliding rod 3045 pulls the top rod 207, so that the top rod 207 drives the rotating head 3048 to approach each other. At this time, the spring sheet 30413 rebounds, so that the rotating rod 3049 is reset, thereby driving the friction head 30411 to reset, so that the friction head 30411 cannot contact the rubber wheel 306 and the abutting wheel 303, so that the power of the rubber wheel 306 cannot be transmitted to the winding shaft 302, so that the winding shaft 302 stops rotating.

[0024] Please refer to Figure 6 , Figure 7 and Figure 8The top of the base 1 is fixedly connected with a tensioning mechanism 4, which includes two sets of fixed seats 401, which are fixedly connected to the top of the base 1, and a first pressure roller 402 is rotatably connected between the two sets of fixed seats 401. A set of sliders 403 are slidably connected to the inner wall of each set of fixed seats 401, and a second pressure roller 404 is rotatably connected between the two sets of sliders 403. The bottom end of the slide bar 3045 is fixedly connected with a pressure spring 405, and the bottom end of the pressure spring 405 is fixedly connected to the bottom end of the slide bar 3045. The inner wall of the fixed seat 401 is fixedly connected, and two groups of reduction components 406 are fixedly connected to the top of the base 1. The reduction component 406 includes an outer cover 4061, and the outer cover 4061 is fixedly connected to the top of the base 1. The inner wall of the outer cover 4061 is rotatably connected to a rotating shaft 4062. The end of the rotating shaft 4062 is fixedly connected to one end of the first pressure roller 402. The outer wall of the rotating shaft 4062 is fixedly sleeved with an abutment disk 4063, and the outer wall of the rotating shaft 4062 is slidably sleeved with a sliding disk 4064. The sliding plate 4064 is located between the abutment plate 4063 and the inner wall of the outer cover 4061. The side wall of the sliding plate 4064 is fixedly connected with a plurality of connecting strips 4065. The connecting strips 4065 are slidably connected to the side wall of the abutment plate 4063. The side wall of the abutment plate 4063 is provided with a plurality of notches that match the connecting strips 4065. The side of the sliding plate 4064 close to the abutment plate 4063 is provided with a plurality of inclined grooves 4066. The inner wall of each group of inclined grooves 4066 is slidably connected with a group of counterweights. Block 4067, the counterweight block 4067 is a cylindrical metal block, a plurality of groups of first grinding discs 4068 are fixedly connected to one side of the sliding disk 4064 away from the abutting disk 4063, a plurality of groups 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.

[0025] The pressure spring 405 pushes the slider 403 to slide upward, so that the slider 403 drives the second pressure roller 404 to slide upward, so that the second pressure roller 404 and the first pressure roller 402 tightly clamp the face paper. When the face paper is rolled up, the face paper drives the first pressure roller 402 and the second pressure roller 404 to rotate, the first pressure roller 402 drives the rotating shaft 4062 to rotate, the rotating shaft 4062 drives the abutment plate 4063 to rotate, and the abutment plate 4063 drives the sliding plate 4064 to rotate through the connecting strip 4065. As the winding speed becomes faster and faster, the rotation speed of the first pressure roller 402 is accelerated, thereby driving the rotation speed of the rotating shaft 4062 to accelerate, and finally the rotation speed of the abutment plate 4063 and the sliding plate 4064 is accelerated. The faster the sliding plate 4064 rotates, the faster it will bring The faster the dynamic counterweight 4067 rotates, the greater the centrifugal force on the counterweight 4067. At this time, the counterweight 4067 slides outward along the inclined groove 4066, thereby pushing the sliding plate 4064 away from the abutment plate 4063, causing the sliding plate 4064 to compress the separation spring 40610 and drive the first grinding plate 4068 to approach the second grinding plate 4069. At this time, the friction between the first grinding plate 4068 and the second grinding plate 4069 causes the sliding plate 4064 to encounter resistance when rotating, and the abutment plate 4063 shaft 4062 and the first pressure roller 402 rotate coaxially, so the first pressure roller 402 encounters rotation resistance, so that the face paper is always in a straight state during the winding process, thereby preventing inconsistent winding tightness during the winding process and avoiding wrinkles in the face paper.

[0026] When in use, two detection methods are used to perform double detection on the gypsum board facing paper to ensure that there will be no errors in the detection results, and through 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 smaller stroke to make the second hydraulic plate extend a longer length, so that the staff can see the detection value more intuitively when observing the first pointer 208 and the first scale plate 209, thereby making the detection results more accurate and the detection process more convenient. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
