Description

Technical Field

[0001] This utility model relates to the field of fragrance detection technology, specifically a fragrance safety detection device. Background Technology

[0002] Fragrances and flavorings are blends of various spices that have a specific aroma and can be directly used to scent plant products. However, the safety of fragrances and flavorings is of paramount importance. Potential issues such as pesticide residues, heavy metal contamination, excessive microorganisms, and illegal additives may pose a threat to human health. Therefore, safety testing is necessary.

[0003] A current Chinese patent (publication number: CN219434456U) discloses a fingerprint spectrum detection device for plant fragrances and flavorings. The device includes a main body with a fixed shell at its upper end, an inlet at the upper end of the fixed shell, a collection box on the side of the fixed shell, and a filter screen inside the fixed shell. This invention, by incorporating a filter screen, cylinder, elastic rod, first bevel gear, second bevel gear, worm gear, worm, stirring paddle, cleaning plate, connecting piece, lead screw, button, guide rod, outlet, and baffle, not only achieves thorough sieving of plant fragrances and flavorings, ensuring the quality of detection, but also facilitates the mixing of plant fragrances and flavorings with pharmaceuticals, greatly improving the detection accuracy of the device.

[0004] During operation, the aforementioned equipment first sieves the spices using a sieving component, and then uses a detection device to perform safety testing on the spices. However, during the sieving process, a cleaning brush is used to clean larger spice particles from the sieve. But in actual use, when the spice particles are the same size as the mesh size of the sieve, they often get stuck in the mesh, making them difficult to clean and affecting the efficiency of subsequent sieving and testing. Furthermore, during the cleaning process, the equipment pushes the stuck spices into a collection box for collection, without processing the stuck spices, which undoubtedly leads to a waste of experimental samples. Utility Model Content

[0005] The purpose of this invention is to provide a fragrance safety testing device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a fragrance safety testing device, including a mounting box and a screen that is vertically slidably installed inside the mounting box.

[0007] A reciprocating lead screw is rotatably connected inside the mounting box. A cleaning component is threaded onto the reciprocating lead screw for cleaning spices that are clogged on the screen. A crushing roller is rotatably connected inside the cleaning component. A first servo motor that drives the reciprocating lead screw to rotate is connected to one side of the mounting box.

[0008] The collection box is attached to the top of the installation box, and a separator mesh is connected inside the collection box;

[0009] An exhaust fan is connected to the top of the mounting box, and the exhaust end of the exhaust fan is connected to the collection box.

[0010] Furthermore, the cleaning component also includes,

[0011] The second bevel gear is connected to the crushing roller, and the first bevel gear is meshed on the second bevel gear. The top of the cleaning component is connected to a second servo motor that drives the first bevel gear to rotate.

[0012] Furthermore, an abutment plate is rotatably connected inside the mounting box, wherein,

[0013] When the contact plate rotates, it can intermittently contact the screen, driving the screen to slide vertically up and down;

[0014] The transmission gear is located on the rear side of the mounting box and is coaxially mounted with the contact plate. A drive rack is meshed on the transmission gear.

[0015] A turntable is rotatably connected to the rear side of the mounting box. A mounting column is slidably mounted on the turntable, and a transmission block is rotatably connected to the mounting column. The other end of the transmission block is rotatably connected to the drive rack.

[0016] The third servo motor, located at the rear of the mounting box, is used to drive the turntable to rotate.

[0017] Furthermore, a mounting bracket is connected to the rear side of the mounting box, the third servo motor is connected to the mounting bracket, a synchronous pulley is connected to the drive end of the third servo motor, and a synchronous belt is connected between the synchronous pulley and the turntable.

[0018] Furthermore, a mounting plate is connected to the turntable, a connecting block is connected to the mounting column, a transmission screw is threaded onto the connecting block, and a limit plate is connected to the other end of the transmission screw.

[0019] Furthermore, the side of the limiting plate opposite to the mounting plate is integrally formed with anti-slip texture.

[0020] Furthermore, the mounting box is connected to a buckle, and the drive rack is slidably connected within the buckle.

[0021] Furthermore, a connecting plate is connected inside the mounting box, and a return spring is connected to the connecting plate. The other end of the return spring is connected to the screen.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. This setup is implemented in the screening stage. The screen efficiently separates large particles and insufficiently mixed fragrances, ensuring that the fragrances entering subsequent testing meet preliminary requirements. Subsequently, the first servo motor drives the reciprocating screw to move the cleaning component back and forth, effectively clearing material blockages from the screen. The exhaust fan and crushing roller work together; the exhaust fan adsorbs the blockage material, the crushing roller crushes it, and then it flows back to the installation box via the collection box. This avoids waste of experimental samples, reduces testing costs, and improves overall testing efficiency.

[0024] 2. Activating the third servo motor, through the linkage of the turntable, mounting column, transmission block, drive rack, and transmission gear, causes the contact plate to continuously contact the screen, significantly accelerating the screening efficiency, effectively reducing screen clogging, and improving the quality and speed of spice screening. Furthermore, by changing the distance between the mounting column and the center of the turntable, the rotation frequency of the contact plate can be flexibly adjusted to suit different screening requirements.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-7 This utility model provides a technical solution: a fragrance safety testing device, comprising a mounting box 1 and a screen 2 vertically slidably disposed within the mounting box 1.

[0035] A reciprocating screw 301 is rotatably connected inside the mounting box 1. A cleaning component 302 is threadedly connected to the reciprocating screw 301 for cleaning the spices clogging the screen 2. A crushing roller 303 is rotatably connected inside the cleaning component 302. A first servo motor 307 that drives the reciprocating screw 301 to rotate is connected to one side of the mounting box 1.

[0036] Collection box 304 is connected to the top of installation box 1, and a separator net 305 is connected inside collection box 304;

[0037] An exhaust fan 306 is connected to the top of the mounting box 1, and the exhaust end of the exhaust fan 306 is connected to the collection box 304.

[0038] It should be noted that a stirring component, a conveying component, and a detection component can be installed at the bottom of the installation box 1. The stirring component is used to stir the medicine and the sieved fragrance, while the conveying component is used to convey the mixed fragrance. Finally, the safety of the fragrance can be detected by the detection component. The detection component can be equipped with a pesticide residue detection unit, a heavy metal detection unit, a microbial detection unit, and an illegal additive detection unit, one or more of which can be detected by enzyme inhibition method, atomic absorption spectrometry, microbial culture and counting technology, and high performance liquid chromatography, respectively. This is existing technology and will not be described in detail here. As for the stirring component, please refer to the existing technology (a fingerprint spectrum detection device for plant fragrances, publication number: CN219434456U).

[0039] The separator 305 divides the collection box 304 into a negative pressure space and a reflux space. The reflux space has a discharge port that is connected to the top of the installation box 1. The crushed and adsorbed fragrance particles can enter the reflux space and flow back into the installation box 1.

[0040] In practice, the fragrance to be tested is placed in the installation box 1. At this time, the screen 2 can perform preliminary screening of the fragrance. Larger particles of impurities or insufficiently mixed fragrance are left on the screen 2, while fragrance that meets the requirements passes through the screen 2 and enters the subsequent testing stage.

[0041] As screening proceeds, screen 2 may become clogged with material, affecting the screening effect. At this time, the first servo motor 307 is started, which drives the reciprocating screw 301 to rotate. Subsequently, the cleaning component 302 will perform reciprocating linear motion along the reciprocating screw 301.

[0042] Then, the exhaust fan 306 is started to adsorb the blocked material. The adsorbed material is sucked into the cleaning component 302 and crushed into smaller particles by the rotating crushing roller 303. The particles are then returned to the installation box 1 through the collection box 304, thereby reducing the waste of experimental samples.

[0043] See Figure 5 The cleaning component 302 also includes,

[0044] The second bevel gear 6 is connected to the crushing roller 303, and the first bevel gear 5 is meshed on the second bevel gear 6. The top of the cleaning component 302 is connected to a second servo motor 4 that drives the first bevel gear 5 to rotate.

[0045] In practice, starting the second servo motor 4 can drive the first bevel gear 5 to rotate, which in turn drives the second bevel gear 6 to rotate, which in turn drives the crushing roller 303 to rotate, providing a continuous driving force for the crushing roller 303.

[0046] See Figure 3 An abutment plate 701 is rotatably connected inside the mounting box 1.

[0047] When the contact plate 701 rotates, it can intermittently contact the screen 2, driving the screen 2 to slide vertically up and down;

[0048] The transmission gear 705 is set on the rear side of the mounting box 1 and is coaxially arranged with the contact plate 701. The transmission gear 705 is meshed with the drive rack 704.

[0049] Turntable 702 is rotatably connected to the rear side of mounting box 1. Mounting column is slidably provided on turntable 702. Transmission block 703 is rotatably connected to mounting column. The other end of transmission block 703 is rotatably connected to drive rack 704.

[0050] The third servo motor 706 is located on the rear side of the mounting box 1 and is used to drive the turntable 702 to rotate.

[0051] In practice, starting the third servo motor 706 can drive the turntable 702 to rotate, and then the turntable 702 can drive the mounting column to rotate. Then, the transmission block 703 rotatably connected on the mounting column can drive the drive rack 704 to move back and forth. At this time, the transmission gear 705 meshing on the drive rack 704 can rotate continuously, driving the contact plate 701 to rotate, so that the contact plate 701 continuously contacts the screen 2, thereby accelerating the screening efficiency of the screen 2.

[0052] See Figure 4 A mounting bracket is connected to the rear side of the mounting box 1. The third servo motor 706 is connected to the mounting bracket. The drive end of the third servo motor 706 is connected to a synchronous pulley 8. A synchronous belt 9 is connected between the synchronous pulley 8 and the turntable 702.

[0053] In practice, the mounting bracket facilitates the installation of the third servo motor 706, and the synchronous pulley 8 and synchronous belt 9 can be used together to transmit the driving force of the third servo motor 706 to the turntable 702.

[0054] refer to Figure 7 A mounting plate 1001 is connected to the turntable 702, a connecting block 1002 is connected to the mounting column, a transmission screw 1003 is threaded onto the connecting block 1002, and the other end of the transmission screw 1003 is connected to a limit plate 1004.

[0055] It should be noted that the connecting block 1002 has a multi-level boss structure, and its shape is similar to "F".

[0056] In practice, by changing the distance between the mounting column and the center of the turntable 702, the rotation frequency of the contact plate 701 can be further adjusted to adapt to different screening types. By rotating the transmission screw 1003, the limiting plate 1004 can be moved closer to the mounting plate 1001, thereby limiting the position of the mounting column.

[0057] refer to Figure 7 The limiting plate 1004 and the mounting plate 1001 are integrally formed on the side opposite to each other and have anti-slip texture.

[0058] In practice, this setting increases the friction of the limiting plate 1004 and improves its fixing effect.

[0059] refer to Figure 6 The mounting box 1 is connected to a buckle, and the drive rack 704 is slidably connected in the buckle.

[0060] In practice, the latches can limit and guide the sliding of the drive rack 704, further improving the stability of the drive rack 704 during the sliding process.

[0061] refer to Figure 4 The mounting box 1 is connected to a connecting plate 11, and a reset spring 12 is connected to the connecting plate 11. The other end of the reset spring 12 is connected to the screen 2.

[0062] In practice, the reset spring 12 can increase the amplitude of the screen 2 shaking, thereby improving the screening efficiency.

[0063] Working principle: The fragrance to be tested is placed in the installation box 1. At this time, the screen 2 can perform preliminary screening of the fragrance. Larger particles of impurities or insufficiently mixed fragrance are left on the screen 2, while fragrances that meet the requirements pass through the screen 2 and enter the subsequent testing stage.

[0064] As screening proceeds, screen 2 may become clogged with material, affecting the screening effect. At this time, the first servo motor 307 is started, which drives the reciprocating screw 301 to rotate. Subsequently, the cleaning component 302 will perform reciprocating linear motion along the reciprocating screw 301.

[0065] Then, the exhaust fan 306 is started to adsorb the blocked material. The adsorbed material is sucked into the cleaning component 302 and crushed by the rotating crushing roller 303 in the cleaning component 302, cut into smaller particles, and then returned to the installation box 1 through the collection box 304, thereby reducing the waste of experimental samples.

[0066] Starting the third servo motor 706 can drive the turntable 702 to rotate, and then the turntable 702 can drive the mounting column to rotate. Then the transmission block 703 rotatably connected on the mounting column can drive the drive rack 704 to move back and forth. At this time, the transmission gear 705 meshing on the drive rack 704 can rotate continuously, driving the contact plate 701 to rotate, so that the contact plate 701 continuously contacts the screen 2, thereby accelerating the screening efficiency of the screen 2.

[0067] By changing the distance between the mounting column and the center of the turntable 702, the rotation frequency of the contact plate 701 can be further adjusted to adapt to different screening types. By rotating the transmission screw 1003, the limiting plate 1004 can be moved closer to the mounting plate 1001, thereby limiting the position of the mounting column.
