Description

Technical Field

[0001] The invention relates to the technical field of isomalt production detection, in particular to a purity detection device for isomalt production. Background Art

[0002] Isomalt is a common sugar substitute and a commonly used additive in food production. After isomalt is produced, manufacturers need to randomly inspect multiple samples to control the quality of the goods produced, and use the sampling test data to make a basis for judging the quality of the finished product.

[0003] Patent announcement number CN118425546B discloses a purity detection device and detection method for isomalt production. To address the problem that the existing detection device cannot automatically configure the detection solution in equal proportion according to the mass of isomalt, the patent includes a base, the base is fixedly connected to a spectrophotometer, the base is fixedly connected to a first guide plate and a second guide plate, the first guide plate and the second guide plate are both placed with evenly distributed measuring cups, a first fixed plate is fixedly connected between the first guide plate and the second guide plate, the first fixed plate is fixedly connected to evenly distributed pressure sensors, the base is fixedly connected to a first fixed frame, and the first fixed frame is fixedly connected to evenly distributed syringes. The patent automatically detects the weight of isomalt through a pressure sensor, and accurately adds the solution to achieve the purpose of quickly and accurately preparing the detection solution.

[0004] However, the device still has some shortcomings: the device can accurately add solution through a pressure sensor, but after the solution is added into the measuring cup, the solution is easily blocked by isomalt and is difficult to quickly penetrate into the bottom of the measuring cup, resulting in reduced dilution and mixing effects of the solution on the isomalt in the measuring cup, which can easily cause data errors when isomalt is detected by a spectrophotometer. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a purity detection device for isomalt production, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented by the following technical solutions: A purity detection device for isomalt production, comprising a workbench, a slide groove is provided at the left end of the workbench, a conveying platform is provided at the left end of the workbench, two electric slide rails are symmetrically provided on the top of the workbench, a spectrophotometer is provided on the right side of the top of the workbench, a support assembly is provided on the top of the workbench, a solution tank is provided inside the support assembly, and a telescopic tube is provided at the bottom of the solution tank;

[0007] An anti-error device is provided inside the support assembly, an anti-overflow device is provided inside the anti-error device, and an anti-corrosion device is provided inside the anti-overflow device;

[0008] The anti-error device includes a sliding plate, the bottom of which is slidably installed inside the electric slide rail, the sliding plate is provided with a limiting groove on the side close to the axis of the workbench, an electric push rod is slidably installed inside the limiting groove of the sliding plate, the telescopic end of the electric push rod is fixedly installed on the stabilizing block close to the axis of the workbench, the outer walls of the stabilizing blocks are symmetrically and hingedly provided with stabilizing clamps through torsion springs, a friction roller is rotatably installed inside the U-shaped groove of the stabilizing clamp, the bottom of the outer wall of the fixed end of the electric push rod is fixedly installed on a semi-arc ring, a plurality of resistance blocks are equidistantly and fixedly installed on the side of the electric slide rail close to the axis of the workbench, an elastic sheet is fixedly installed on the side of the sliding plate close to the axis of the workbench, and a knocking column is fixedly installed on the side of the elastic sheet close to the sliding plate.

[0009] According to the above technical solution, a spring is arranged between the fixed end of the electric push rod and the limiting groove of the sliding plate, the outer wall of the stabilizing block is made of soft material, a U-shaped groove is provided at one end of the stabilizing clamp close to the axis of the workbench, and several of the resistance blocks are located on the semi-arc annular arc surface motion trajectory, and the outer wall of the sliding plate is located on the motion trajectory of the knocking column. A measuring cup containing the isomalt sampling sample is placed on the conveying platform, and the measuring cup is conveyed from left to right through the conveying platform. When the measuring cup is conveyed to the bottom center of the supporting assembly, the conveying platform pauses the conveying, and the electric push rod is started while the solution is injected into the measuring cup through the telescopic tube. The telescopic end of the electric push rod drives the stabilizing block to move toward the center of the workbench, and the stabilizing block drives the stabilizing clamp to move synchronously. In the process of the stabilizing clamp driving the friction roller to move toward the center of the workbench, the outer wall of the friction roller contacts the outer wall of the measuring cup. As the friction roller continues to move, the friction roller generates a rotational force and starts to rotate along the inside of the stabilizing clamp. At this time, the friction roller causes the hinge shaft of the stabilizing clamp to start rotating through the resistance force generated when it contacts the measuring cup, and drives the stabilizing clamp away from the center of the stabilizing block. It moves in an arc track. When the stabilizing clamp fixes the measuring cup, the electric slide rail drives the sliding plate to move toward the spectrophotometer. The sliding plate prompts the stabilizing clamp to drive the measuring cup to move synchronously. The staff pours the test sample in the measuring cup transported by the stabilizing clamp into the internal container of the spectrophotometer to test the purity of the sample. At the same time, the electric slide rail and the electric push rod are reset, and the process repeats. When the electric push rod moves toward the spectrophotometer with the sliding plate, the electric push rod drives the semi-arc ring to move synchronously. The arc surface at the bottom of the semi-arc ring contacts the top of the resistance block to produce resistance. When the semi-arc ring is reset, the elastic sheet will drive the knocking column to knock on the sliding plate back and forth to generate slight vibration, and the measuring cup will vibrate synchronously through the transmission of force.

[0010] According to the above technical solution, the anti-spillage device includes a push plate, a U-shaped frame, a round rod and a pressure plate. The bottom of the push plate is fixedly installed on the top of the telescopic end of the electric push rod, the top of the U-shaped frame is slidably installed on the top of the inner wall of the support assembly, both ends of the round rod are fixedly installed inside the U-shaped frame near the axis of the support assembly, and the top of the pressure plate is hinged to the side of the round rod near the axis of the support assembly.

[0011] The U-shaped frame is provided with a U-shaped groove on its outer wall, and the U-shaped frame contacts the outer wall of the push plate on one side away from the axis of the supporting assembly. A torsion spring is arranged between the top of the pressure plate and the round rod, and the bottom of the pressure plate is hinged at the outer wall of the telescopic end of the telescopic tube. When the telescopic end of the electric push rod moves toward the center of the workbench, it drives the push plate to move synchronously, and the push plate pushes the U-shaped frame to move synchronously, the U-shaped frame drives the round rod to move synchronously, and the round rod drives the pressure plate to move synchronously. The bottom of the pressure plate is limited by the telescopic end of the telescopic tube, causing its own hinge axis to start rotating. At this time, the pressure plate presses the telescopic tube downward with the hinge axis as the axis to start extending. When the push plate moves toward the spectrophotometer along with the electric push rod, the U-shaped frame is reset by the spring force after losing the resistance of the push plate, and the above structures are reset synchronously.

[0012] According to the above technical solution, the anti-spillage device also includes a plurality of friction wheels, a reciprocating screw, a transmission plate, an L-shaped contact plate and a swing plate. The plurality of friction wheels are symmetrically and rotatably installed inside the U-shaped frame. The outer wall of the friction wheel contacts the top of the inner wall of the supporting assembly. Both ends of the reciprocating screw are fixedly installed on the side of the friction wheel close to the center of the U-shaped frame. The transmission plate penetrates inside and is slidably installed on the outer wall of the reciprocating screw. A hot air blower is arranged inside the transmission plate. The side of the transmission plate away from the round rod is slidably connected to the inner wall of the U-shaped frame. The top of the L-shaped contact plate is fixedly installed on the bottom of the transmission plate. The top of the swing plate is hinged to the inside of the U-shaped groove of the U-shaped frame by a torsion spring. The outer wall of the swing plate is located on the movement trajectory of the L-shaped contact plate. The U-shaped frame drives the friction When the wheel moves toward the center of the workbench, the outer wall of the friction wheel begins to rotate inside the U-shaped frame due to the friction between it and the top of the inner wall of the supporting assembly. When the friction wheel rotates, it drives the reciprocating screw to rotate. When the reciprocating screw rotates, the reciprocating spiral groove on its own outer wall limits the internal block of the transmission plate, so that the transmission plate can slide horizontally along the inner wall of the U-shaped frame. The transmission plate drives the internal hot air blower to move synchronously. At the same time, the transmission plate drives the L-shaped resistance plate to move synchronously. When the L-shaped resistance plate moves away from the center of the U-shaped frame, it resists the outer wall of the swing plate. The hinge shaft between the swing plate and the U-shaped groove of the U-shaped frame starts to rotate, and drives the swing plate to move in an arc trajectory away from the center of the U-shaped frame with the hinge shaft as the axis. Then the swing plate is reset by the torsion spring.

[0013] The U-shaped telescopic frame can be used to support a plurality of movable frames, and the movable frame can be used to support a plurality of movable frames, and the movable frame can be used to support a plurality of movable frames.

[0014] According to the above technical solution, the anti-erosion device also includes a rotating rod, a plurality of brush plates, a cam, a slotted scraper and an arc block. Both ends of the rotating rod are fixedly mounted on the side of the pulley close to the center of the dust reduction screen. Several of the brush plates are fixedly mounted on the outer wall of the rotating rod. The cam penetrates through and is fixedly mounted on the edge of the outer wall of the rotating rod. The bottom of the slotted scraper penetrates through and is slidably mounted on the bottom of the inner wall of the dust reduction screen. The bottom of the arc block is fixedly mounted on the top edge of the slotted scraper.

[0015] According to the above technical solution, a number of brush plates are equidistantly distributed on the outer wall of the rotating rod, the outer wall of the brush plate contacts the outer wall of the swing plate, a spring is arranged between the bottom of the slotted scraper and the dust reduction mesh plate, the top of the arc block contacts the outer wall of the cam, and the rotation of the pulley drives the rotating rod to rotate, and the rotation of the rotating rod drives the brush plate to revolve and continuously brush the outer wall surface of the swing plate. At the same time, the rotation of the rotating rod drives the cam to rotate, and the rotation of the cam disengages from the resistance to the arc block, that is, the arc block no longer presses the slotted scraper, and the slotted scraper moves upward by the spring force. When the cam contacts the arc block again, the arc block presses the slotted scraper to reset, and this process repeats.

[0016] The present invention provides a purity detection device for isomalt production, which has the following beneficial effects:

[0017] (1) The present invention adopts the arrangement of an error prevention device, and cooperates with a sliding plate, an electric push rod, a stabilizing block, a stabilizing clamp, a friction roller, a semi-arc ring, a resistance block, an elastic sheet and a knocking column. The friction roller reduces the difficulty of fixing the measuring cup with the stabilizing clamp, and ensures the stability of the measuring cup during the fixing and inspection process, thereby preventing the measuring cup from tilting and collapsing to cause sample overflow, thereby avoiding contamination of the workbench and changes in sampling inspection indicators. At the same time, the friction roller enables the stabilizing clamp to be adaptively adjusted to cope with measuring cups of different diameters, thereby shortening the inspection preparation time and improving the practicality of the equipment. At the same time, the measuring cup is made to evenly and quickly mix the sample and the solution through up and down movement during the inspection process, and the mixing uniformity of the two is further improved through vibration force, thereby avoiding the solution being blocked by isomalt and being difficult to quickly penetrate into the bottom of the measuring cup, resulting in a reduced dilution effect of the solution on the isomalt in the measuring cup, thereby preventing data errors when isomalt is detected by a spectrophotometer.

[0018] (2) The present invention adopts the arrangement of an anti-overflow device, and cooperates with an electric push rod, a push plate, a U-shaped frame, a round rod, a pressure plate, a friction wheel, a reciprocating screw, a transmission plate, an L-shaped contact plate and a swing plate. The pressure plate enables the telescopic end of the telescopic tube to inject the solution into the measuring cup at a distance closer to the measuring cup, thereby ensuring that the solution is injected deeper into the isomalt sample during the injection process, thereby improving the confusion effect in the subsequent inspection process, and at the same time preventing the telescopic tube from being too far away from the measuring cup, thereby increasing the possibility of sample overflow in the measuring cup during the solution injection process; and effectively expanding the range of movement of the hot air gun, and using the hot air gun to evenly heat the measuring cup and the stabilizing block and other soft materials, so that the measuring cup further accelerates the reaction speed of the sample and the solution by heat, thereby shortening the waiting time for detection, and at the same time heating the soft material to cause slight softening, so that it can better fit the outer wall of the measuring cup, and at the same time relying on the reciprocating swinging swinging plate, effectively expanding the interception and shielding range of the raised sample powder.

[0019] (3) The present invention, through the setting of the anti-corrosion device, cooperates with the swing plate, U-shaped telescopic frame, dust suppression mesh plate, pulley, rotating rod, brush plate, cam, slotted scraper and arc block, and relies on the reciprocating sliding and resetting of the dust suppression mesh plate to uniformly adsorb the sample powder intercepted by the swing plate, that is, the dust suppression mesh plate is used to realize relatively concentrated collection of powder for subsequent maintenance and cleaning, thereby preventing the sample powder from adhering to the outer wall surface of the swing plate and not being cleaned in time, thereby aggravating its oxidation rate; and relies on the revolution of the brush plate to finely brush the outer wall of the swing plate, thereby further reducing the possibility of powder residue on the surface of the swing plate, and the powder brushed by the brush plate is adsorbed by the dust suppression mesh plate to prevent it from falling into the measuring cup and interfering with the detection result. At the same time, the slotted scraper reciprocates up and down during the movement of the dust suppression mesh plate, so that the powder can be evenly distributed after entering the dust suppression mesh plate, thereby further reducing the possibility of powder overflow during the movement of the dust suppression mesh plate.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figure 1-Figure 8 One embodiment of the present invention is: a purity detection device for isomalt production, comprising a workbench 1, a slide slot is provided at the left end of the workbench 1, a conveying platform 2 is provided at the left end of the workbench 1, two electric slide rails 21 are symmetrically provided on the top of the workbench 1, a spectrophotometer 22 is provided on the right side of the top of the workbench 1, a support assembly 3 is provided on the top of the workbench 1, a solution box 31 is provided inside the support assembly 3, and a telescopic tube 32 is provided at the bottom of the solution box 31;

[0031] An anti-error device 4 is provided inside the support assembly 3, an anti-overflow device 5 is provided inside the anti-error device 4, and an anti-corrosion device 6 is provided inside the anti-overflow device 5;

[0032] The anti-error device 4 includes a sliding plate 41, the bottom of which is slidably installed inside the electric slide rail 21, a limiting groove is provided on the side of the sliding plate 41 close to the axis of the workbench 1, an electric push rod 42 is slidably installed inside the limiting groove of the sliding plate 41, the telescopic end of the electric push rod 42 is fixedly installed on the stabilizing block 43 close to the axis of the workbench 1, the outer wall of the stabilizing block 43 is symmetrically and hingedly provided with a stabilizing clamp 44 through a torsion spring, a friction roller 45 is rotatably installed inside the U-shaped groove of the stabilizing clamp 44, the bottom of the outer wall of the fixed end of the electric push rod 42 is fixedly installed on a semi-arc ring 46, a plurality of resistance blocks 47 are equidistantly and fixedly installed on the side of the electric slide rail 21 close to the axis of the workbench 1, an elastic sheet 48 is fixedly installed on the side of the sliding plate 41 close to the axis of the workbench 1, and a knocking column 49 is fixedly installed on the side of the elastic sheet 48 close to the sliding plate 41.

[0033] A spring is arranged between the fixed end of the electric push rod 42 and the limit groove of the sliding plate 41, the outer wall of the stabilizing block 43 is made of soft material, a U-shaped groove is provided at one end of the stabilizing clamp 44 close to the axis of the workbench 1, a plurality of abutting blocks 47 are all located on the arc motion track of the semi-arc ring 46, and the outer wall of the sliding plate 41 is located on the motion track of the knocking column 49. Through the above cooperation, the friction roller 45 is relied on to reduce the difficulty of fixing the measuring cup by the stabilizing clamp 44, and the stability of the measuring cup during the fixing and inspection process is ensured, so as to prevent the measuring cup from tilting and collapsing, causing the sample to overflow, and avoid contaminating the workbench 1 and changing the sampling inspection. The friction roller 45 enables the stabilizing clamp 44 to be adaptively adjusted to cope with measuring cups of different diameters, thereby shortening the test preparation time and improving the practicability of the equipment. Through the above cooperation, the measuring cup can evenly and quickly mix the sample and the solution by moving up and down during the inspection process, and the vibration force can further improve the mixing uniformity of the two, thereby preventing the solution from being blocked by isomalt and being difficult to quickly penetrate into the bottom of the measuring cup, resulting in a reduction in the dilution effect of the solution on the isomalt in the measuring cup, thereby preventing data errors from occurring when isomalt is detected by the spectrophotometer 22.

[0034] When in use, place the measuring cup containing the isomalt sample on the conveying platform 2, and convey the measuring cup from left to right through the conveying platform 2. When the measuring cup is conveyed to the bottom center of the supporting assembly 3, the conveying platform 2 stops conveying, and injects the solution into the measuring cup through the telescopic tube 32, while starting the electric push rod 42. The telescopic end of the electric push rod 42 drives the stabilizing block 43 to move toward the center of the workbench 1, and the stabilizing block 43 drives the stabilizing clamp 44 to move synchronously. In the process of the stabilizing clamp 44 driving the friction roller 45 to move toward the center of the workbench 1, the outer wall of the friction roller 45 contacts the outer wall of the measuring cup. As the friction roller 45 continues to move, the friction roller 45 generates a rotational force and starts to rotate along the inside of the stabilizing clamp 44. At this time, the friction roller 45 rotates with itself. The resistance force generated when the measuring cup contacts causes the hinge shaft of the stabilizing clamp 44 to start rotating, and drives the stabilizing clamp 44 to move in an arc trajectory away from the center of the stabilizing block 43. When the stabilizing clamp 44 has completed fixing the measuring cup, the electric slide rail 21 will drive the sliding plate 41 to move towards the spectrophotometer 22. The sliding plate 41 causes the stabilizing clamp 44 to drive the measuring cup to move synchronously. The staff pours the test sample in the measuring cup transported by the stabilizing clamp 44 into the internal container of the spectrophotometer 22 for sample purity detection. At the same time, the electric slide rail 21 and the electric push rod 42 are reset, and the process is repeated. Through the above cooperation, the friction roller 45 is used to reduce the difficulty of fixing the measuring cup by the stabilizing clamp 44, and the stability of the measuring cup during the fixing and inspection process is ensured to prevent the measuring cup from tilting. The oblique collapse phenomenon causes the sample to overflow, avoiding contamination of the workbench 1 and changes in the sampling inspection index. At the same time, the friction roller 45 enables the stabilizing clamp 44 to be adaptively adjusted to cope with measuring cups of different diameters, shortening the inspection preparation time and improving the practicality of the equipment. When the electric push rod 42 moves with the sliding plate 41 toward the spectrophotometer 22, the electric push rod 42 drives the semi-arc ring 46 to move synchronously. The arc surface at the bottom of the semi-arc ring 46 contacts the top of the resistance block 47 to generate a resistance force. The semi-arc ring 46 is guided by the arc surface of the resistance block 47 and slides upward along the inside of the limiting groove of the sliding plate 41. Then the electric push rod 42 is reset by the spring force. This reciprocating process enables the electric push rod 42 to cause the measuring cup inside the stabilizing clamp 44 to move up and down, and at the same time the semi-arc ring 46 moves upward. When the semi-arc ring 46 is reset, the elastic sheet 48 will drive the knocking column 49 to knock the sliding plate 41 back and forth to produce slight vibrations through its own elastic reset process, and the measuring cup is caused to vibrate synchronously through the force transmission. Through the above cooperation, the measuring cup can evenly and quickly mix the sample and the solution through up and down movement during the inspection process, and the mixing uniformity of the two is further improved through the vibration force, so as to avoid the solution being blocked by isomalt and having difficulty in quickly penetrating into the bottom of the measuring cup, resulting in a reduced dilution effect of the solution on the isomalt in the measuring cup, thereby preventing data errors when isomalt is detected by the spectrophotometer 22.

[0035] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-spillage device 5;

[0036] The anti-overflow device 5 includes a push plate 51, a U-shaped frame 52, a round rod 53 and a pressure plate 54. The bottom of the push plate 51 is fixedly installed on the top of the telescopic end of the electric push rod 42, the top of the U-shaped frame 52 is slidably installed on the top of the inner wall of the support component 3, both ends of the round rod 53 are fixedly installed inside one end of the U-shaped frame 52 close to the axis of the support component 3, and the top of the pressure plate 54 is hinged to the side of the round rod 53 close to the axis of the support component 3.

[0037] A U-shaped groove is provided on the outer wall of the U-shaped frame 52, and the U-shaped frame 52 contacts the outer wall of the push plate 51 on the side away from the axis of the support assembly 3. A torsion spring is arranged between the top of the pressure plate 54 and the round rod 53, and the bottom of the pressure plate 54 is hinged on the outer wall of the telescopic end of the telescopic tube 32. Through the above cooperation, the pressure plate 54 enables the telescopic end of the telescopic tube 32 to inject the solution into the measuring cup at a distance closer to the measuring cup, thereby ensuring that the solution penetrates deeper into the isomalt sample during the injection process, thereby improving the confusion effect in the subsequent inspection process, and at the same time avoiding the telescopic tube 32 being too far away from the measuring cup, thereby increasing the possibility of sample overflowing from the measuring cup during the solution injection process.

[0038] The anti-spill device 5 also includes a plurality of friction wheels 55, a reciprocating screw rod 56, a transmission plate 57, an L-shaped contact plate 58 and a swing plate 59. The plurality of friction wheels 55 are symmetrically and rotatably mounted inside the U-shaped frame 52. The outer wall of the friction wheel 55 contacts the top of the inner wall of the support assembly 3. Both ends of the reciprocating screw rod 56 are fixedly mounted on the side of the friction wheel 55 close to the center of the U-shaped frame 52. The transmission plate 57 penetrates inside and is slidably mounted on the outer wall of the reciprocating screw rod 56. A hot air blower is arranged inside the transmission plate 57. The transmission plate 57 is slidably connected to the inner wall of the U-shaped frame 52 on the side away from the round rod 53. The top of the L-shaped contact plate 58 is fixedly mounted. At the bottom of the transmission plate 57, the top of the swing plate 59 is hinged inside the U-shaped groove of the U-shaped frame 52 through a torsion spring, and the outer wall of the swing plate 59 is located on the movement trajectory of the L-shaped resistance plate 58. The above cooperation effectively expands the activity range of the hot air gun, and the hot air gun is used to evenly heat the soft materials such as the measuring cup and the stabilizing block 43, so that the measuring cup relies on heat to further accelerate the reaction speed of the sample and the solution, shorten the waiting time for detection, and heat the soft material to cause it to soften slightly, so that it can better fit the outer wall of the measuring cup. At the same time, relying on the reciprocating swinging swing plate 59, the interception and shielding range of the raised sample powder is effectively expanded.

[0039] When in use, when the telescopic end of the electric push rod 42 moves toward the center of the workbench 1, it drives the push plate 51 to move synchronously, the push plate 51 pushes the U-shaped frame 52 to move synchronously, the U-shaped frame 52 drives the round rod 53 to move synchronously, the round rod 53 drives the pressing plate 54 to move synchronously, the bottom of the pressing plate 54 is limited by the telescopic end of the telescopic tube 32, prompting its own hinge axis to start rotating, at this time, the pressing plate 54 presses the telescopic tube 32 downward with the hinge axis as the axis to start extending, when the push plate 51 moves toward the spectrophotometer 22 along with the electric push rod 42, the U-shaped frame 52 loses the resistance of the push plate 51 and moves through the spring The spring force is reset, and the above structures are reset synchronously. Through the above cooperation, the pressure plate 54 is used to enable the telescopic end of the telescopic tube 32 to inject the solution into the measuring cup at a distance closer to the measuring cup, ensuring that the solution is injected deeper into the isomalt sample during the injection process, improving the confusion effect in the subsequent inspection process, and at the same time avoiding the telescopic tube 32 from being too far away from the measuring cup, increasing the possibility of sample overflowing in the measuring cup during the solution injection process; in the process of the U-shaped frame 52 driving the friction wheel 55 to move toward the center of the workbench 1, the outer wall of the friction wheel 55 is opened by the friction between the outer wall of the support assembly 3 and the top of the inner wall The friction wheel 55 starts to rotate inside the U-shaped frame 52. When the friction wheel 55 rotates, it drives the reciprocating screw 56 to rotate. When the reciprocating screw 56 rotates, the reciprocating spiral groove on its outer wall restricts the internal block of the transmission plate 57, so that the transmission plate 57 can slide horizontally along the inner wall of the U-shaped frame 52. The transmission plate 57 drives the internal hot air blower to move synchronously. At the same time, the transmission plate 57 drives the L-shaped contact plate 58 to move synchronously. When the L-shaped contact plate 58 moves away from the center of the U-shaped frame 52, it contacts the outer wall of the swing plate 59. The hinge shaft between the swing plate 59 and the U-shaped groove of the U-shaped frame 52 starts to rotate, and drives The swing plate 59 moves in an arc trajectory with the hinge axis as the axis toward the center of the U-shaped frame 52, and then the swing plate 59 is reset by the torsion spring. The above cooperation effectively expands the range of motion of the hot air gun, and the hot air gun is used to evenly heat the soft materials such as the measuring cup and the stabilizing block 43, so that the measuring cup relies on heat to further accelerate the reaction speed of the sample and the solution, shortening the waiting time for detection, and heating the soft material to cause slight softening so that it can better fit the outer wall of the measuring cup. At the same time, the reciprocating swinging swing plate 59 is used to effectively expand the interception and shielding range of the raised sample powder.

[0041] The anti-corrosion device 6 includes a U-shaped telescopic frame 61, a dust reduction mesh plate 62 and a plurality of pulleys 63. The top of the U-shaped telescopic frame 61 is hinged to the bottom of the U-shaped frame 52 by a torsion spring, and the U-shaped telescopic frame 61 has a built-in spring. The outer wall of the dust reduction mesh plate 62 is slidably installed on the side of the swing plate 59 close to the axis of the U-shaped frame 52. The top of the dust reduction mesh plate 62 is hinged to the bottom of the telescopic end of the U-shaped telescopic frame 61. A plurality of pulleys 63 are symmetrically and rotatably installed inside the top of the dust reduction mesh plate 62. The outer wall of the pulley 63 contacts the outer wall of the swing plate 59. Through the above cooperation, the reciprocating sliding and resetting of the dust reduction mesh plate 62 are relied on to uniformly adsorb the sample powder intercepted by the swing plate 59, that is, the dust reduction mesh plate 62 is relied on to achieve relatively concentrated collection of the powder for subsequent maintenance and cleaning, to prevent the sample powder from adhering to the outer wall surface of the swing plate 59 and not being cleaned in time, thereby exacerbating its oxidation rate.

[0042] The anti-erosion device 6 also includes a rotating rod 64, a plurality of brush plates 65, a cam 66, a slotted scraper 67 and a curved block 68. Both ends of the rotating rod 64 are fixedly mounted on the side of the pulley 63 close to the center of the dust reduction mesh plate 62. The plurality of brush plates 65 are fixedly mounted on the outer wall of the rotating rod 64. The cam 66 penetrates inside and is fixedly mounted on the edge of the outer wall of the rotating rod 64. The bottom of the slotted scraper 67 penetrates and is slidably mounted on the bottom of the inner wall of the dust reduction mesh plate 62. The bottom of the curved block 68 is fixedly mounted on the top edge of the slotted scraper 67.

[0043] A number of brush plates 65 are equidistantly distributed on the outer wall of the rotating rod 64, the outer wall of the brush plate 65 contacts the outer wall of the swing plate 59, a spring is arranged between the bottom of the slotted scraper 67 and the dust reduction mesh plate 62, the top of the arc block 68 contacts the outer wall of the cam 66, and the above cooperation relies on the revolution of the brush plate 65 to brush the outer wall of the swing plate 59 in detail, further reducing the possibility of powder residue on the surface of the swing plate 59, and the powder brushed by the brush plate 65 is adsorbed by the dust reduction mesh plate 62 to prevent it from falling into the measuring cup and interfering with the detection result. At the same time, the slotted scraper 67 reciprocates up and down during the movement of the dust reduction mesh plate 62, so that the powder can be evenly distributed after entering the dust reduction mesh plate 62, further reducing the possibility of powder overflow during the movement of the dust reduction mesh plate 62.

[0044] When in use, when the swing plate 59 moves in an arc trajectory away from the center of the U-shaped frame 52, it will drive the dust reduction mesh plate 62 to move synchronously, and the dust reduction mesh plate 62 drives the U-shaped telescopic frame 61 to move synchronously. The top of the U-shaped telescopic frame 61 is limited by the U-shaped frame 52, prompting its own hinge axis to start to rotate, and the hinge axis at the telescopic end of the U-shaped telescopic frame 61 generates a rotating force and pushes the dust reduction mesh plate 62 to slide downward along the outer wall of the swing plate 59, and the dust reduction mesh plate 62 drives the pulley 63 to move synchronously, and the pulley 63 starts to rotate due to the friction between it and the outer wall of the swing plate 59. The pulley 63 reduces the sliding resistance between the dust reduction mesh plate 62 and the swing plate 59 through rolling friction. Through the above cooperation, relying on the reciprocating sliding and resetting of the dust reduction mesh plate 62, the sample powder intercepted by the swing plate 59 is uniformly adsorbed, that is, relying on the dust reduction mesh plate 62 to achieve relatively concentrated collection of powder for subsequent maintenance and cleaning, to prevent the sample powder from adhering to the outer wall surface of the swing plate 59 and not being cleaned in time, thereby exacerbating its oxidation rate; When the pulley 63 rotates, it drives the rotating rod 64 to rotate. When the rotating rod 64 rotates, it drives the brush plate 65 to revolve and continuously brushes the outer wall surface of the swing plate 59. At the same time, when the rotating rod 64 rotates, it drives the cam 66 to rotate. When the cam 66 rotates, it breaks away from the resistance to the arc block 68, that is, the arc block 68 no longer presses the slotted scraper 67, and the slotted scraper 67 moves upward by the elastic force of the spring. When the cam 66 contacts the arc block 68 again, the arc block 68 presses the slotted scraper 67 to reset, and so on. The brush plate 65 revolves to finely brush the outer wall of the swing plate 59, further reducing the possibility of powder residue on the surface of the swing plate 59, and the powder brushed by the brush plate 65 is adsorbed by the dust reduction mesh plate 62 to prevent it from falling into the measuring cup and interfering with the detection result. At the same time, the slotted scraper 67 reciprocates up and down during the movement of the dust reduction mesh plate 62, so that the powder can be evenly distributed after entering the dust reduction mesh plate 62, further reducing the possibility of powder overflow during the movement of the dust reduction mesh plate 62.
