[0018] 4. After the inspection is completed, the lifting frame rises and resets, and at the same time drives the two guide rollers to move closer to each other through the connecting rod and the swing connecting rod. At this time, driven by the ratchet bar, the ratchet drives the placement roller to rotate through the first belt transmission member, and the placement roller drives the receiving roller to rotate synchronously through the second belt transmission member, so as to automatically remove the inspected aluminum foil from the top of the lower inspection frame, and send the uninspected area to the top of the lower inspection frame, so as to realize the function of continuous inspection of aluminum foil.

The bottom of the two guide rollers 104 are passed around and wound onto the receiving roller 102. An upper detection frame 2 is arranged in the detection box 1. A control cylinder 201 is installed on the fixed top frame 101. The telescopic rod of the control cylinder 201 is fixedly connected to the upper detection frame 2. The control cylinder 201 pushes the upper detection frame 2 to move up and down in the detection box 1. A lower detection frame 3 is fixedly connected in the detection box 1. The aluminum foil paper to be detected is located on the top of the lower detection frame 3.

The head and tail of the aluminum foil roll to be tested are respectively connected with a section of transparent material that does not need to be tested. Before testing, the aluminum foil roll to be tested is placed on the placement roller 103, and then the transparent material at the head of the aluminum foil roll passes through the rectangular hole on the side wall of the detection box 1 into the detection box 1, and then passes through the rectangular hole at the other end of the detection box 1 through the transmission of the two guide rollers 104. When the end of the aluminum foil to be tested moves to the top detection position of the lower detection frame 3, , the transparent material at the end of the aluminum foil roll is wound around the receiving roller 102, and then the control cylinder 201 is started to push the upper detection frame 2 down. After the upper detection frame 2 and the lower detection frame 3 clamp the aluminum foil, the control cylinder 201 is closed. At this time, the detection mechanism will detect the aluminum foil. After the detection is completed, the control cylinder 201 pulls the upper detection frame 2 to rise and reset, and then rotates the receiving roller 102. The receiving roller 102 pulls the detected aluminum foil away from the top of the lower detection frame 3, so that the undetected aluminum foil moves to the top of the lower detection frame 3 to continue detection.

[0034] Embodiment 2: Based on embodiment 1, Figure 2-Figure 7 , Fig. 9 and Fig.10As shown, the detection mechanism includes a fixed gas tank 202, a return spring 203, a mobile inflating plug 2031, an upper sealing ring 204, a fixed shaft 205, a sliding pressure rod 2051, a wedge-shaped block 2052, a sliding pressure plate 206, a mobile shaft sleeve 2061, a straight guide rod 207, a return spring 2071, a lower sealing ring 302, a top pressurizing component and a bottom decompressing component.

The movable shaft sleeve 2061 is fixedly connected to the sliding pressure plate 206. The upper sealing ring 204 is fixedly connected with a straight guide rod 207. The straight guide rod 207 passes through the sliding pressure plate 206 and is slidably connected thereto. The sliding pressure plate 206 and the upper sealing ring 204 are connected via a return spring 2071. The return spring 2071 is sleeved on the straight guide rod 207. One end of the return spring 2071 is fixedly connected to the sliding pressure plate 206, and the other end is fixedly connected to the upper sealing ring 204. The fixed shaft 205 is slidably connected with a sliding pressure rod 2051. A wedge-shaped stopper 2052 is slidably connected, and a lower sealing ring 302 is fixedly connected to the top of the lower detection frame 3. When the upper detection frame 2 descends, the upper sealing ring 204 and the lower sealing ring 302 clamp the aluminum foil to be detected. The top booster assembly is installed in the upper sealing ring 204, and the top booster assembly is used to increase the air pressure on the top of the aluminum foil. The bottom decompression assembly is installed in the lower detection frame 3, and the bottom decompression assembly is used to reduce the air pressure at the bottom of the aluminum foil. The top booster assembly and the bottom decompression assembly cooperate to form a pressure difference on both sides of the aluminum foil to detect the aluminum foil.

[0035] like Figure 6 and Figure 7As shown, the top booster assembly includes a U-shaped slide bar 2041, a connecting spring 2042, a rotating baffle 2043, an arc-shaped slide groove 2044 and a hemispherical protrusion 2053.

One end of the connecting spring 2042 is fixedly connected to the U-shaped slide bar 2041, and the other end is fixedly connected to the upper sealing ring 204. When the upper sealing ring 204 contacts the lower sealing ring 302, the lower sealing ring 302 will push the U-shaped slide bar 2041 to rise along the upper sealing ring 204. The upper sealing ring 204 is rotatably connected with a rotating baffle. Plate 2043, before detection, the rotating baffle 2043 blocks the through hole between the upper sealing ring 204 and the upper detection frame 2, the sliding pressure rod 2051 passes through the rotating baffle 2043 and is slidably connected thereto, an arc-shaped slide groove 2044 is provided in the rotating baffle 2043, a hemispherical protrusion 2053 is fixedly connected to the sliding pressure rod 2051, the hemispherical protrusion 2053 is located in the arc-shaped slide groove 2044 in the rotating baffle 2043, and the U-shaped sliding rod 2041 rises by pushing the sliding pressure rod 2051 to rise. During the rising process of the sliding pressure rod 2051, the rotating baffle 2043 is pushed to rotate under the action of the hemispherical protrusion 2053 and the arc-shaped slide groove 2044 and the through hole of the upper sealing ring 204 is opened.

[0036] like Fig. 9 and Fig.10 As shown, the bottom decompression assembly includes a lifting frame 301, a guide rod 303, a support spring 304, a fixed pad 305, a fixed rod 306 and a sliding sealing plug 307. The lifting frame 301 is slidably connected in the lower detection frame 3, and the guide rod 303 is fixed in the lower detection frame 3. The guide rod 303 passes through the lifting frame 301 and is slidably connected thereto. The lifting frame 301 is connected to the lower detection frame 3 through the support spring 304, and the support spring 304 is sleeved outside the guide rod 303. The support spring 304 is 04 One end is fixedly connected to the lifting frame 301, and the other end is fixedly connected to the lower detection frame 3. A fixed pad 305 is fixedly connected in the lower detection frame 3. The fixed pad 305 is located at the bottom of the lifting frame 301. The fixed pad 305 is used to limit the height of the lifting frame 301. A fixed rod 306 is fixedly connected to the lifting frame 301, and the fixed rod 306 is located directly below the movable inflatable plug 2031. A sliding sealing plug 307 is slidably connected in the lower detection frame 3, and the sliding sealing plug 307 is fixedly connected to the lifting frame 301 through a sliding rod.

[0037] like Fig.10 As shown, it also includes a connecting rod 4, a pressure ring 402 and a clamping spring 403. The lifting frame 301 is fixedly connected to the connecting rod 4, and the pressure ring 402 is slidably connected to the connecting rod 4. The pressure ring 402 and the connecting rod 4 are connected through the clamping spring 403. One end of the clamping spring 403 is fixedly connected to the pressure ring 402, and the other end is fixedly connected to the connecting rod 4.

[0038] During the descent of the upper detection frame 2 and the device thereon, the mobile inflatable plug 2031 will contact the fixed rod 306 on the lifting frame 301. Since the rigidity coefficient of the reset spring 203 is greater than the rigidity coefficient of the support spring 304, the mobile inflatable plug 2031 pushes the lifting frame 301 to descend along the lower detection frame 3 through the fixed rod 306 and compresses the support spring 304. When the lifting frame 301 descends, the pressure ring 402 is driven to descend through the connecting rod 4. The pressure ring 402 descends and presses the aluminum foil paper on the lower detection frame 3, thereby making the aluminum foil paper close to the lower sealing ring, and forming a closed space between the aluminum foil paper and the sliding sealing plug 307. At this time, the lifting frame 301 can continue to descend, and the compression spring 403 between the pressure ring 402 and the connecting rod 4 is compressed, and the sliding sealing The plug 307 then descends and increases the distance between it and the aluminum foil. At this time, the aluminum foil forms a sealed space with the sliding sealing plug 307 and the lower detection frame 3, and external gas cannot enter the lower detection frame 3. The air pressure at the bottom of the aluminum foil decreases. When the lifting frame 301 contacts the fixed cushion block 305, the lifting frame 301 cannot continue to descend. At this time, the mobile inflatable plug 2031 is supported by the fixed rod 306 and cannot continue to descend. As the upper detection frame 2 and the fixed gas tank 202 continue to descend, the mobile inflatable plug 2031 will slide along the fixed gas tank 202 and push the gas inside it into the upper detection frame 2. At this time, the air pressure on the top of the sliding pressure plate 206 in the upper detection frame 2 increases. Since the sliding pressure rod 2051 provides support to it from the inside of the wedge-shaped stopper 2052, the sliding pressure plate 206 is pressed against the upper detection frame 2052. The plate 206 is restricted by the wedge-shaped stopper 2052 and cannot slide downward along the fixed shaft 205. When the U-shaped slide bar 2041 contacts the lower sealing ring 302, as the upper detection frame 2 and the upper sealing ring 204 continue to descend, the U-shaped slide bar 2041 slides upward relative to the upper sealing ring 204 and compresses the connecting spring 2042. The U-shaped slide bar 2041 pushes the sliding pressure rod 2051 to slide upward along the fixed shaft 205. When the sliding pressure rod 2051 slides upward along the fixed shaft 205, it drives the rotating baffle 2043 to rotate in the upper sealing ring 204 through the hemispherical protrusion 2053 and the arc-shaped slide groove 2044 to open the fan-shaped through hole in the upper sealing ring 204. When the upper sealing ring 204 is fitted with the lower sealing ring 302, the control cylinder 201 is closed, and the aluminum foil The paper, the upper sealing ring 204 and the sliding pressure plate 206 form a sealed space in the upper detection frame 2, and at this time the wedge-shaped stopper 2052 is out of contact with the sliding pressure rod 2051, and the wedge-shaped stopper 2052 loses support. Due to the increase in air pressure in the upper half of the upper detection frame 2, the sliding pressure plate 206 contacts the inclined surface at the top of the wedge-shaped stopper 2052 and presses it into the fixed shaft 205. Under the pressure of the air pressure in the upper half of the upper detection frame 2, the sliding pressure plate 206 and the movable shaft sleeve 2061 will slide downward along the fixed shaft 205 and the straight guide rod 207 and compress the return spring 2071. The distance between the sliding pressure plate 206 and the aluminum foil paper becomes shorter, and the air pressure at the top of the aluminum foil paper increases, thereby forming an air pressure difference between the top and bottom of the aluminum foil paper to detect the aluminum foil paper.As the sliding pressure plate 206 descends, the movable sleeve 2061 descends accordingly and restricts the wedge-shaped stopper 2052 inside the fixed shaft 205. The sliding pressure rod 2051 and the U-shaped slide bar 2041 are restricted by the wedge-shaped stopper 2052 and cannot be reset. The air pressure at the top of the sliding pressure plate 206 applies a downward thrust to it, and the air pressure at the bottom of the sliding pressure plate 206 and the return spring 2071 apply an upward thrust to it. When the thrusts at the upper and lower ends of the sliding pressure plate 206 are the same, the sliding pressure plate 206 The height of the upper detection frame 2 will remain stable; after the detection is completed, the control cylinder 201 is started and the upper detection frame 2 and its internal devices are pulled up and reset. During the rising process of the upper detection frame 2, the mobile inflatable plug 2031 first draws the gas in the upper detection frame 2 into the fixed gas tank 202 under the action of the reset spring 203 to reduce the air pressure on the top of the sliding pressure plate 206 in the upper detection frame 2. Under the push of the return spring 2071, the sliding pressure plate 206 and the moving shaft sleeve 2061 move upward along the fixed shaft 205 and the straight guide rod 207. Sliding reset, when the sliding pressure plate 206 returns to its original position, the sliding pressure plate 206 is just above the wedge-shaped stopper 2052. At this time, the wedge-shaped stopper 2052 is no longer restricted by the sliding pressure plate 206 and the movable shaft sleeve 2061. The connecting spring 2042 pushes the U-shaped sliding rod 2041 and the sliding pressure rod 2051 to descend and reset. When the sliding pressure rod 2051 descends, it pushes the wedge-shaped stopper 2052 out of the fixed shaft 205, so that the top inclined surface of the wedge-shaped stopper 2052 contacts the sliding pressure plate 206 again. When the movable inflatable plug 2031 and the reset spring 203 are restored, the upper detection frame 2 continues to rise, and the support spring 304 pushes the lifting frame 301 to rise. During the lifting process of the lifting frame 301, the connecting rod 4 pushes the pressing ring 402 and the pressing spring 403 to rise and reset to release the restriction on the aluminum foil. After the lifting frame 301 and its upper device rise and reset, the receiving roller 102 is rotated to remove the aluminum foil that has been tested from the top of the lower detection frame 3, so that the aluminum foil to be tested moves to the top of the lower detection frame 3.

[0039] Embodiment 3: Based on embodiment 2, Figure 8 As shown, it also includes a movable rack 208, a rotating shaft 209, a transmission gear 210, a limiting torsion spring 211, a swing rod 212 and a marking pen 213. The movable rack 208 is fixedly connected to the sliding pressure plate 206, and the rotating shaft 209 is rotatably connected in the upper detection frame 2. One end of the rotating shaft 209 located in the upper detection frame 2 is fixedly connected to the transmission gear 210. A limiting torsion spring 211 is provided between the transmission gear 210 and the upper detection frame 2. One end of the rotating shaft 209 located outside the upper detection frame 2 is fixedly connected to the swing rod 212. A straight sliding hole is provided on the swing rod 212, and a slideway is provided at the bottom of the upper detection frame 2. A marking pen 213 is slidably connected in the slideway at the bottom of the upper detection frame 2, and the top of the marking pen 213 is slidably set in the straight sliding hole on the swing rod 212.

[0040] Before the detection, the limit torsion spring 211 can limit the state of the rotating gear and the swing rod 212 through the rotating shaft 209 to prevent the swing rod 212 from shaking. During the detection process, when the height of the sliding pressure plate 206 in the upper detection frame 2 is stable, the lowest tooth of the moving rack 208 contacts the transmission gear 210, and the height of the upper detection frame 2 is maintained for a period of time to detect the aluminum foil. When the aluminum foil is not damaged, the gas will not pass through the aluminum foil into the lower detection frame 3. At this time, the height of the sliding pressure plate 206 will not change, and the marker 213 only marks a point on the surface of the aluminum foil to indicate that this section of the aluminum foil is intact. When the aluminum foil paper being tested is damaged, the gas under the sliding pressure plate 206 in the upper detection frame 2 will enter the lower detection frame 3 through the aluminum foil paper. At this time, the air pressure between the sliding pressure plate 206 and the aluminum foil paper is reduced, and the sliding pressure plate 206 is reduced by the upward thrust. The air pressure on the top of the sliding pressure plate 206 will push the sliding pressure plate 206 to slide downward again. At this time, the moving rack 208 will drop accordingly and drive the rotating shaft 209 to rotate through the transmission gear 210. When the rotating shaft 209 rotates, it will drive the marking pen 213 to slide along the slide at the bottom of the upper detection frame 2 through the swing rod 212 to mark a straight line on the top of the aluminum foil paper to indicate that this section of aluminum foil paper is damaged.

[0041] like Fig. 9 As shown, it also includes a swing link 401, which is hinged on the connecting rod 4, and the other end of the swing link 401 is hinged on the rotating shaft of the guide roller 104. When the lifting frame 301 descends, the connecting rod 4 and the swing link 401 push the two sides of the guide apart to flatten the aluminum foil.

[0042] When the connecting rod 4 descends, the two guide shafts can be pushed to open to both sides through the swing connecting rod 401. When the guide shaft moves, the aluminum foil can be fully unfolded to avoid wrinkles on the surface of the aluminum foil during the detection process, thereby ensuring the detection effect.

[0043] like Figure 1 and Fig.11As shown, it also includes a ratchet bar 5, a ratchet 501, a first belt transmission member 502, a first pulley 5021, a second pulley 5022 and a second belt transmission member 503. The ratchet bar 5 is slidably connected to the outside of the detection box 1. The ratchet bar 5 is connected to the rotating shaft of the guide roller 104 close to the placement roller 103. The ratchet 501 is rotatably connected to the outside of the detection box 1. The ratchet 501 is meshed with the ratchet bar 5. The ratchet 501 is connected to the placement roller 103 through the first belt transmission member 502. The ratchet 501 drives the placement roller 103 to rotate through the first belt transmission member 502. The placement roller 103 and The receiving rollers 102 are connected to each other through the second belt transmission member 503, and the placing roller 103 drives the receiving roller 102 to rotate through the second belt transmission member 503. The first pulley 5021 is coaxially fixed to the ratchet 501, and the second pulley 5022 is coaxially fixed to the placing roller 103. The diameter of the first pulley 5021 is larger than the diameter of the second pulley 5022 to ensure that the placing roller 103 and the receiving roller 102 can rotate a sufficient number of circles each time. The receiving roller 102 will retract the detected aluminum foil, and the placing roller 103 will release the aluminum foil to be detected and move it to the top of the lower detection frame 3.

[0044] When the connecting rod 4 pushes the two guide rollers 104 to slide along the detection box 1 and move away from each other through the swing link 401, the ratchet bar 5 follows one of the guide rollers 104 to slide along the detection box 1. During this process, the ratchet bar 5 will not drive the ratchet wheel 501 to rotate. When the lifting frame 301 rises and resets, the connecting rod pulls the two guide rollers 104 to move closer to each other along the detection box 1 through the swing link 401. At this time, the ratchet bar 5 moves and resets with the guide roller 104 and drives the ratchet wheel 501 to rotate. The ratchet wheel 501 drives the placement roller 103 to rotate through the first belt transmission member 502. 103 drives the receiving roller 102 to rotate through the second belt transmission member 503, and the placing roller 103 and the receiving roller 102 rotate in the same direction. When the placing roller 103 rotates, the aluminum foil roll can be loosened, and when the receiving roller 102 rotates, the aluminum foil can be retracted, wherein the diameter of the first pulley 5021 is larger than the diameter of the second pulley 5022, so as to ensure that the placing roller 103 and the receiving roller 102 are driven to rotate a sufficient number of times during the horizontal movement of the guide roller 104, so that the detected aluminum foil is moved away from the top of the lower detection frame 3, and the aluminum foil to be detected is moved to the top of the lower detection frame 3 for detection.

[0045] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
