Description

Technical Field

[0001] This invention belongs to the field of leather testing, specifically relating to a leather testing device based on a new material. Background Technology

[0002] Leather testing employs optical methods, primarily based on its non-contact and non-destructive characteristics. By analyzing the spectral information reflected or transmitted from the leather surface, optical technology can effectively identify microscopic defects, texture differences, and coating uniformity that are difficult to detect with the naked eye. Simultaneously, using specific spectral bands, the internal chemical components of the leather can be non-destructively tested, such as chromium content and the degree of collagen denaturation, thereby achieving accurate quality grading and authenticity verification.

[0012] In one or more embodiments of the present invention, a spring is provided between the upper surface of the positioning shaft and the lower surface of the translation clamping block, and a spring is provided between the lower surface of the double inclined guide seat and the upper surface of the machine base.

[0013] In one or more embodiments of the present invention, the device placement protection device includes: A hoist, wherein the hoist is fixedly connected to the upper surface of the base, and a lifting seat is slidably connected to the inner surface of the hoist; A magnetic card frame is fixedly connected to the front side of the lifting seat; In one or more embodiments of the present invention, the device placement protection device further includes: Side baffle, the side baffle is fixedly connected to the front side of the hoist; An elastic telescopic rod is fixedly connected to the front side of the hoist, and an L-shaped front baffle is fixedly connected to the free end of the front side of the elastic telescopic rod.

[0014] In one or more embodiments of the present invention, the optical disc imager and the inner surface of the magnetic card frame are engaged, the lower surface of the L-shaped front baffle and the upper surface of the base are slidably connected, the lower top surface of the L-shaped front baffle and the upper surface of the side baffle are slidably connected, the connecting rod and the inner surface of the inner through groove are slidably connected, the card shaft and the inner surface of the inner through groove are slidably connected, the lower surface of the locking plate and the upper surface of the base abut against each other, and a through hole is provided on the inner side of the locking plate, and the inner surface of the through hole is engaged with the card shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the lower abutment plate and the movable plate drive the leather to rotate and keep it perpendicular to the base, thereby aligning the leather surface with the optical disc imager for easy optical inspection. The lower abutment plate and the movable plate then drive the leather to flip, so that the leather face is aligned with the optical disc imager, making the inspection more accurate and comprehensive. The connecting plate drives the lower abutment plate and the movable plate set on both sides of the base to move away from each other, thereby stretching the leather and facilitating the exposure of its surface defects, further improving the inspection accuracy. When the movable plate approaches the lower abutment plate, it can clamp the leather, promoting inspection stability. The reverse rotation of the control screw can drive the movable plate to rise, thereby quickly releasing the leather and making it easy to remove the leather, improving the ease of use of the device. The V-shaped upper pressure plate descends and presses down on the leather, so that the two ends of the leather form a stable V-shaped bend, thereby preventing the leather from being stressed and breaking off from the clamping device during the stretching process, improving the inspection stability. Moreover, the protruding parts of the wider leather can rest on the side guide rod, improving the applicability of the inspection. As the sliding rod moves the long clamping plate downwards and fits against the leather, the edge of the leather that extends beyond the lower plate is clamped between the long clamping plate and the translational clamping block, thus securing it. This improves the stability of the device when inspecting leather of different sizes. Furthermore, when the leather is flipped over, its surface becomes completely parallel to the optical disc imager, making the inspection more accurate. The double-sloped guide seat descends under the influence of spring tension and locks the horizontal bar through the triangular locking block. At this point, the overall fixing device is more stable and does not sway due to external forces, improving the stability of the leather during inspection. The horizontal bar can escape its restriction range through the shorter slope of the double-sloped guide seat and quickly reset, facilitating subsequent unloading and securing of the leather and improving the ease of use of the device. During the lifting and lowering process of the optical disc imager, a more comprehensive scan of the leather can be performed, thereby improving the detection effect. After the device has been in use for a long time, when the optical disc imager needs to be replaced or repaired, it can be removed from the device simply by pulling it off the magnetic card frame. Conversely, after inserting it into the magnetic card frame, the optical disc imager is attracted to the magnetic card frame by its rear magnet, which is convenient for installation and does not require a complicated installation process, thus improving the ease of use of the device. Pushing the L-shaped front baffle backward closes it with the side baffle, thereby protecting the optical disc imager from impact or dust accumulation, which would lead to a decrease in detection effect. The locking shaft is inserted upward into the through hole opened on the inside of the locking plate and locked, thereby locking the L-shaped front baffle and improving the protection effect. The elastic return action of the elastic telescopic rod pushes the L-shaped front baffle forward and away from the side baffle. At this time, the lifting seat can be controlled to drive the magnetic card frame and the optical disc imager to lift and lower, and perform optical detection on the leather. The operation is simple, further improving the ease of use of the device. Attached Figure Description

[0018] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] like Figure 1-8As shown, one embodiment of the present invention is: a leather detection device based on a new material, including a base 1, support seats 2 fixedly connected to both sides of the upper surface of the base 1, a disc imager 6 disposed above the base 1, a fixing plate 3 fixedly connected to the top front side of the support seats 2, a rotating sleeve shaft 4 rotatably connected to the top inner surface of the support seats 2, a cylinder 5 fixedly connected to the side of the rotating sleeve shaft 4 away from the disc imager 6, a connecting plate 7 fixedly connected to the free end of the cylinder 5, a flipping detection stabilizing device 8 disposed above the base 1, the flipping detection stabilizing device 8 being used to lock the leather and the fixing device during detection, and an equipment placement protection device 9 disposed on the top of the base 1, the equipment placement... The protective device 9 protects the testing equipment. The lower abutment plate 10 and the movable plate 12 rotate the leather and keep it perpendicular to the base 1, thereby aligning the leather surface with the optical disc imager 6 for easy optical inspection. The lower abutment plate 10 and the movable plate 12 then rotate the leather, aligning the leather facet with the optical disc imager 6 for more accurate and comprehensive inspection. The connecting plate 7 includes the lower abutment plate 10, which is fixedly connected to the bottom side surface of the connecting plate 7. Limiting guide rails 11 are fixedly connected to the front and rear sides of the upper surface of the lower abutment plate 10. The movable plate 12 is slidably connected to the side surface of the limiting guide rails 11. The connecting plate 7 drives the lower abutment plate 10 and the movable plate 12, which are located on both sides of the base 1, to move away from each other. The leather is then stretched to expose surface defects, further improving detection accuracy. When the movable plate 12 approaches the lower abutment plate 10, it clamps the leather, promoting detection stability. Reverse rotation of the adjusting screw 13 causes the movable plate 12 to rise, quickly releasing the leather for easy removal and improving ease of use. The connecting plate 7 also includes the adjusting screw 13, which is rotatably connected to the upper surface of the lower abutment plate 10. The V-shaped upper pressure plate 14 is fixedly connected to the lower surface of the movable plate 12, and the V-shaped lower folding plate 15 is fixedly connected to the upper surface of the lower abutment plate 10. The side guide rod 16 is fixedly connected to the front and rear sides of the lower abutment plate 10. The fixing plate 3 is used to control the motor. The motor is fixed in place and connected to the rotating sleeve shaft 4 via a synchronous belt. The free end of the cylinder 5 slides through one side of the rotating sleeve shaft 4 and extends to the other side. The limiting guide rail 11 and the connecting plate 7 are fixedly connected on the side away from the rotating sleeve shaft 4. The movable plate 12 and the connecting plate 7 are slidably connected on the side away from the rotating sleeve shaft 4. The movable plate 12 and the adjusting screw 13 are threadedly connected on their circumferential surfaces. The V-shaped upper pressure plate 14 descends and presses down on the leather, so that the two ends of the leather form a stable V-shaped bend. This prevents the leather from being stressed and breaking off from the clamping device during the stretching process, thus improving the stability of the inspection. In addition, the protruding parts of the wider leather can rest on the side guide rod 16, improving the applicability of the inspection.

[0020] Working principle: When optical inspection of leather is required, the leather is placed on the base 1 and then positioned between the lower abutment plate 10 and the movable plate 12. The movable plate 12 is pressed down to clamp the leather. At this time, the motor is started, and the motor drives the rotating sleeve shaft 4 to rotate via the synchronous belt. The rotating sleeve shaft 4 drives the lower abutment plate 10 and the movable plate 12 to rotate via the connecting plate 7. The lower abutment plate 10 and the movable plate 12 then drive the leather to rotate and keep it perpendicular to the base 1, thereby aligning the surface of the leather with the optical disc imager 6 for easy optical inspection. The rotating sleeve shaft 4 is rotated in the opposite direction, and the rotating sleeve shaft 4 drives the lower abutment plate 10 and the movable plate 12 to rotate in the opposite direction via the connecting plate 7. The lower abutment plate 10 and the movable plate 12 then drive the leather to flip over, so that the flipped leather faces the optical disc imager 6, making the inspection more accurate and comprehensive. During the inspection process, the cylinder 5 is activated, and the cylinder 5 retracts, causing the connecting plate 7 to move closer to the support base 2. The connecting plate 7 then drives the lower abutment plates 10 located on both sides of the base 1. The movable plate 12 is moved away from the leather, thus stretching it and exposing surface defects, further improving detection accuracy. Rotating the adjusting screw 13 causes the movable plate 12 to slide up and down between the limiting guide rails 11 via the thread. When the movable plate 12 approaches the lower abutment plate 10, it can clamp the leather, promoting detection stability. Rotating the adjusting screw 13 in the opposite direction can drive the movable plate 12 to rise, thus quickly releasing the leather and making it easy to remove, improving the ease of use of the device. After the leather is placed on the lower abutment plate 10, the two ends of the leather are lifted by the V-shaped lower folding plate 15 to create an angle. At this time, the movable plate 12 descends and drives the V-shaped upper pressure plate 14 to descend and press the leather, so that the two ends of the leather form a stable V-shaped fold, thus preventing the leather from being stressed and breaking off from the clamping device during the stretching process, improving detection stability. In addition, the protruding parts of wider leather can rest on the side guide rod 16, improving the applicability of the detection.

[0021] like Figure 1-8As shown, based on the above embodiments, in another embodiment of the present invention, the flipping detection stabilizing device 8 includes a horizontal strut 81, which is fixedly connected to the end of the side guide rod 16 away from the lower abutment plate 10. A translation clamp 82 is slidably connected to the outer surface of the horizontal strut 81, and a sliding rod 83 is slidably connected to the inner surface of the translation clamp 82. A positioning shaft 84 is fixedly connected to the bottom end of the sliding rod 83, and a long clamp 85 is fixedly connected to the top end of the sliding rod 83. The sliding rod 83 drives the long clamp 85 to descend and fit against the leather. At this time, the edge of the leather that exceeds the range of the lower abutment plate 10 is clamped between the long clamp 85 and the translation clamp 82 and thus fixed, improving the stability of the device when detecting leather of different sizes. Moreover, when the leather is flipped, the surface of the leather can be completely parallel to the optical disc imager 6, making the detection more accurate. 8 also includes an inner through groove 86, which is opened on the top of the base 1. The inner surface of the inner through groove 86 is slidably connected to a slide rod 87. The double inclined guide seat 88 is fixedly connected to the top of the slide rod 87. The side surface of the double inclined guide seat 88 is fixedly connected to a triangular block 89. The double inclined guide seat 88 is lowered by the spring tension and locks the crossbar 81 through the triangular block 89. At this time, the fixing device is more stable and is not shaken by external forces, which improves the stability of the leather during inspection. A spring is set between the upper surface of the positioning shaft 84 and the lower surface of the translation clamp 82. A spring is set between the lower surface of the double inclined guide seat 88 and the upper surface of the base 1. The crossbar 81 can be released from its restriction range through the shorter inclined surface of the double inclined guide seat 88 and then quickly reset, which facilitates the subsequent unloading and fixing of the leather and improves the ease of use of the device.

[0022] Working principle: After the leather is fully draped over the side guide rod 16 and the crossbar 81, the long clamp 85 is pulled upwards. At this time, the long clamp 85 drives the slide rod 83 to slide within the translation clamp 82. The slide rod 83 then drives the positioning shaft 84 to rise. When the positioning shaft 84 rises, it compresses the spring 84 between itself and the lower surface of the translation clamp 82, thus pushing the translation clamp 82, causing it to slide back and forth on the side guide rod 16. When the translation clamp 82 is aligned with the front and rear edges of the leather, the long clamp 85 is released. At this time, the positioning shaft 84 moves downwards to reset under the influence of the spring 81. When the positioning shaft 84 moves downwards, it drives the slide rod 83 to slide within the translation clamp 82. 3. Slide downwards, and the slide bar 83 drives the long clamping plate 85 to descend and fit against the leather. At this time, the edge of the leather that exceeds the range of the lower abutment plate 10 is clamped between the long clamping plate 85 and the translation clamping block 82 and thus fixed, improving the stability of the device when detecting leather of different sizes. At this time, the leather is flipped over, and the surface of the leather can be completely parallel to the optical disc imager 6, making the detection more accurate. The cylinder 5 drives the lower abutment plate 10 to flip through the connecting plate 7. The lower abutment plate 10 then drives the side guide rod 16 and the crossbar 81 to flip. When the crossbar 81 rotates to near the upper surface of the base 1, it first meets the longer inclined surface of the double inclined guide seat 88. Upon contact, the double-sloped guide seat 88, under pressure, causes the slide rod 87 to slide downwards within the inner through groove 86. Simultaneously, the double-sloped guide seat 88 compresses the spring 2 downwards. When the horizontal strut 81 passes over the longer slope of the double-sloped guide seat 88, the double-sloped guide seat 88 moves upwards and resets under the influence of the spring force. At this point, the horizontal strut 81 rotates in the opposite direction by a certain angle, and then pushes it upwards a certain distance through the lower slope of the triangular latch 89. The triangular latch 89 then causes the double-sloped guide seat 88 to rise a certain distance, making the horizontal strut 81 fit against the vertical surface of the double-sloped guide seat 88. Then, the double-sloped guide seat 88 is pulled upwards by the spring. The force influence decreases and the horizontal bar 81 is locked by the triangular locking block 89. At this time, the fixing device is more stable and will not shake due to external forces, which improves the stability of the leather during testing. After the test is completed, the double inclined guide seat 88 is raised. The double inclined guide seat 88 drives the triangular locking block 89 to move upward and unlock the horizontal bar 81. At this time, the horizontal bar 81 is controlled to move away from the vertical surface of the double inclined guide seat 88, and then the double inclined guide seat 88 is pressed down, so that the horizontal bar 81 can get out of its restriction range through the shorter inclined surface of the double inclined guide seat 88, and then quickly reset, which facilitates the subsequent unloading and fixing of the leather and improves the ease of use of the device.

[0023] like Figure 1-8As shown, in another embodiment of the present invention, based on the above embodiments, the device placement and protection device 9 includes a lifting mechanism 91, which is fixedly connected to the upper surface of the base 1. A lifting seat 92 is slidably connected to the inner surface of the lifting mechanism 91, and a magnetic card frame 93 is fixedly connected to the front side of the lifting seat 92. During the lifting and lowering process, the optical disc imager 6 can perform a more comprehensive scan of the leather, thereby improving the detection effect. After the device has been working for a long time, when the optical disc imager 6 needs to be replaced or repaired, it can be removed from the magnetic card frame 93 and taken off the device. After disassembly, and by inserting it into the magnetic card frame 93, the optical disc imager 6 is attracted to the magnetic card frame 93 by its rear magnet, facilitating installation without a complicated process and improving the ease of use of the device. The equipment placement protection device 9 also includes a side baffle 94, which is fixedly connected to the front side of the hoist 91. An elastic telescopic rod 95 is fixedly connected to the front side of the hoist 91, and an L-shaped front baffle 96 is fixedly connected to the free end of the front side of the elastic telescopic rod 95. A locking plate 97 is fixedly connected to the bottom front side of the L-shaped front baffle 96, and a connecting rod 98 is fixedly connected to the slide rod 87. On the rear side of the bottom circumferential surface, the rear end of the connecting rod 98 is fixedly connected to a retaining pin 99. Pushing the L-shaped front baffle 96 backward closes it with the side baffle 94, thus protecting the optical disc imager 6 from impact or dust accumulation, which could reduce its detection performance. The retaining pin 99 is inserted upward into the through hole on the inner side of the locking plate 97 and locked, thereby locking the L-shaped front baffle 96 and improving the protective effect. The inner surface of the optical disc imager 6 and the magnetic card frame 93 are engaged. The lower surface of the L-shaped front baffle 96 is slidably connected to the upper surface of the base 1. The lower top surface of the L-shaped front baffle 96 is connected to the side baffle 94. The upper surface of plate 94 is slidably connected, the connecting rod 98 is slidably connected to the inner surface of the inner through groove 86, the locking shaft 99 is slidably connected to the inner surface of the inner through groove 86, the lower surface of locking plate 97 abuts against the upper surface of base 1, a through hole is opened on the inner side of locking plate 97, and the inner surface of the through hole is engaged with locking shaft 99. The elastic restoring action of elastic telescopic rod 95 pushes L-shaped front baffle 96 forward and away from side baffle 94. At this time, the lifting seat 92 can be controlled to drive the magnetic card frame 93 and optical disc imager 6 to rise and fall and perform optical detection on leather. The operation is simple and further improves the ease of use of the device.

[0024] Working principle: When optical inspection of leather is required, the lifting mechanism 91 is activated. The lifting mechanism 91 drives the lifting platform 92 to rise and fall. The lifting platform 92 then drives the magnetic card frame 93 and the optical disc imager 6 to rise and fall. During the rising and falling process, the optical disc imager 6 can perform a more comprehensive scan of the leather, thereby improving the inspection effect. After long-term operation, when the optical disc imager 6 needs to be replaced or repaired, it can be removed from the device simply by unplugging it from the magnetic card frame 93. Conversely, inserting it into the magnetic card frame 93 will remove the optical disc imager 6. The device is easily installed by attaching to the magnetic card frame 93 via a rear magnet, eliminating the need for a complicated installation process and improving ease of use. When optical inspection of the leather is no longer required, the lifting seat 92 descends to the bottom of the lifting machine 91. The lifting seat 92 then moves the magnetic card frame 93 and the optical disc imager 6 to the bottom of the lifting machine 91. At this point, the magnetic card frame 93 and the optical disc imager 6 are inserted between the two side baffles 94. Pushing the L-shaped front baffle 96 backward closes it with the side baffles 94, thus protecting the optical disc imager 6 and preventing damage. When the L-shaped front baffle 96 is pushed backward, the double-sloping guide seat 88 is pressed down. The double-sloping guide seat 88 drives the slide rod 87 to slide downward. The slide rod 87 drives the connecting rod 98 to slide down. The connecting rod 98 then drives the locking shaft 99 to slide down. After the L-shaped front baffle 96 and the side baffle 94 are closed, the double-sloping guide seat 88 is released. The spring 2 drives the double-sloping guide seat 88 to rise and reset. The double-sloping guide seat 88, through the slide rod 87 and the connecting rod 98, drives the locking shaft 99 to rise and reset, so that the locking shaft 99 inserts upward into the locking plate. The L-shaped front baffle 96 is locked in the through hole on the inner side of the 97, thus improving the protective effect. When the optical disc imager 6 is to be used, the locking pin 99 is pressed down to pull the locking pin 99 away from the locking plate 97. When the locking plate 97 and the L-shaped front baffle 96 lose their limit, the elastic return action of the elastic telescopic rod 95 pushes the L-shaped front baffle 96 forward and away from the side baffle 94. At this time, the lifting seat 92 can be controlled to drive the magnetic card frame 93 and the optical disc imager 6 to rise and fall and perform optical inspection on the leather. The operation is simple and further improves the ease of use of the device.
