Description

Technical Field

[0001] This utility model relates to the field of food safety production and testing technology, specifically to an online brushing sampler for allergen residues in a baking production line. Background Technology

[0002] In the production of baked goods (such as bread, biscuits, and cakes), because production lines are often used to process products with multiple formulations, cross-contamination of allergens (such as peanuts, nuts, milk, eggs, soy, and gluten) is highly likely to occur when products are processed alternately. This contamination poses a serious health threat to people with allergies. Therefore, food production companies must establish strict allergen control plans, a key component of which is the regular monitoring of contact surfaces of production line equipment (such as conveyor belts, cutters, molds, and hoppers) to verify the effectiveness of cleaning procedures.

[0003] Currently, the industry's monitoring of allergen residues mainly relies on a combination of traditional sampling and laboratory analysis methods. After the production line stops, quality inspectors use sterile gauze, cotton swabs, or sponge swabs to apply a certain amount of buffer solution or pure water to the pre-set sampling points. The collected swabs are then placed in sample tubes, labeled, and transported via cold chain to the central laboratory for analysis.

[0004] Because the production line for baked goods is long and requires many sampling points, traditional manual allergen residue sampling requires a lot of manpower and time, and the entire sampling process is lengthy and inefficient. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an online brushing sampler for allergen residues in baking production lines, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides an online brushing sampler for allergen residues in a baking production line, comprising: Baking conveyor belt; The sampling mechanism includes a fixed seat fixedly connected to the outside of the baking conveyor belt, a drive motor is provided above the fixed seat, a transmission shaft is fixedly connected to the output shaft of the drive motor, brush assemblies distributed at equal intervals are fixedly connected to the outside of the transmission shaft, a cylinder is installed on the top of the fixed seat, a top plate is fixedly connected to the telescopic end of the cylinder, and a servo motor is fixedly connected to the bottom of the top plate. The brushing assembly includes internally threaded cylinders fixedly connected at equal intervals to the outside of the drive shaft. The inner wall of the internally threaded cylinder is threaded with a threaded rod, and a rotatable brushing roller is provided at the end of the threaded rod away from the internally threaded cylinder.

[0007] Preferably, the output shaft of the servo motor is fixedly connected to a motor mount, and the drive motor is mounted on the bottom of the motor mount.

[0008] Preferably, the bottom of the top plate is fixedly connected to two symmetrically distributed vertical rods, and the top of the fixing seat has two symmetrically distributed circular holes. The ends of the two vertical rods away from the top plate pass through the circular holes and are slidably connected to the inner wall of the circular holes.

[0009] Preferably, a connecting block is fixedly connected to the end of the threaded rod away from the internal threaded cylinder, a spring is fixedly connected to the side of the connecting block away from the threaded rod, and a U-shaped frame is fixedly connected to the end of the spring away from the connecting block.

[0010] Preferably, the inner wall of the brush roller is fixedly connected to an installation shaft, and the installation shaft is rotatably connected to the inner wall of the U-shaped frame via a bearing.

[0011] Preferably, two symmetrically distributed limiting rods are fixedly connected to the outside of the U-shaped frame, and two through holes are opened on the outside of the connecting block. The end of the limiting rod away from the U-shaped frame passes through the through hole and is slidably connected to the inner wall of the through hole.

[0012] Preferably, the brush roller is made of food-grade silicone.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model, by setting up a sampling mechanism, allows for the downward movement of the brush assembly on the transmission shaft when allergen sampling is required on the baking food production line. This brings the brush assembly into contact with the conveyor belt on the baking food production line, thereby sampling allergens at different locations on the conveyor belt. This eliminates the need for manual sampling, reducing labor costs for enterprises. Furthermore, multiple sets of rotatable brush assemblies can sequentially sample allergens on the conveyor belt without frequent replacement, greatly improving the sampling efficiency of allergens on the baking food production line.

[0014] 2. By setting up a brush assembly, this utility model can increase the sampling range of a single sampling when sampling allergens on the conveyor belt of baked goods. Multiple brush assemblies are distributed in a straight line at equal intervals, which can simultaneously sample different positions on the conveyor belt. Through large-area and multi-position sampling, it helps to improve the accuracy of the test results. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments. Example 1:

[0020] Reference Figure 1-4 This is the first embodiment of the present invention, which discloses an online brushing sampler for allergen residues in a baking production line, comprising: Baking conveyor belt 1; The sampling mechanism 2 includes a fixed base 26 fixedly connected to the outside of the baking conveyor belt 1, which serves as the supporting foundation for the entire mechanism. A drive motor 25 is installed above the fixed base 26. The output shaft of the drive motor 25 is fixedly connected to a transmission shaft 29. A brush assembly 22 with equal spacing along the axial direction is fixedly connected to the outside of the transmission shaft 29. A cylinder 23 is installed on the top of the fixed base 26. A top plate 21 is fixedly connected to the telescopic end of the cylinder 23. A servo motor 27 is fixedly connected to the bottom of the top plate 21.

[0021] The above design enables the servo motor 27 to drive the entire drive motor 25 and transmission shaft 29 to rotate horizontally, thereby switching different brushing components 22 to the working position; while the cylinder 23 is responsible for controlling the vertical lifting and lowering of the entire component unit, so that the brushing component 22 can contact or leave the conveyor belt surface.

[0022] Specifically, the output shaft of the servo motor 27 is fixedly connected to the motor mount 28, and the drive motor 25 is installed at the bottom of the motor mount 28.

[0023] The motor mount 28 is used for mounting the drive motor 25, and the servo motor 27 can drive the motor mount 28 to rotate through the output shaft, thereby driving the drive motor 25 together with the transmission shaft 29 and the brush assembly 22 on its outer side to rotate, making it convenient to remove the brush assembly 22 on the outer side of the transmission shaft 29.

[0024] Specifically, the bottom of the top plate 21 is fixedly connected with two symmetrically distributed vertical rods 24, and the top of the fixing seat 26 has two symmetrically distributed circular holes. The ends of the two vertical rods 24 away from the top plate 21 pass through the circular holes and are slidably connected to the inner wall of the circular holes.

[0025] To ensure the smoothness and accuracy of the lifting process, this guiding mechanism effectively prevents the top plate 21 and its components below from shifting or rotating during the lifting process, ensuring that the brushing assembly 22 can press vertically and accurately against the conveyor belt.

[0026] In this embodiment, when allergen sampling is required, the control system is activated, cylinder 23 retracts, and guided by top plate 21 and vertical rod 24, drive motor 25, transmission shaft 29, and all brushing components 22 move steadily downwards. When the brushing component 22 at the lowest working position contacts the conveyor belt surface, it completes brushing sampling at that position under the action of the moving conveyor belt or its own design. This process is fully automated, requiring no manual intervention, directly reducing the company's dependence on labor and related costs.

[0027] After a single sampling is completed, cylinder 23 extends, lifting the component. Then, drive motor 25 rotates precisely, for example, 90 degrees under a control signal, driving all brush assemblies 22 to rotate together via transmission shaft 29, switching the next unused set of brush assemblies 22 to the sampling position. This lifting and lowering sampling process is then repeated. This design, with multiple sets of brush assemblies 22 working sequentially, allows the device to perform multiple continuous samplings without interrupting the process to change sampling tools, greatly improving sampling efficiency. Example 2:

[0028] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that: The brushing assembly 22 includes an internally threaded cylinder 221 fixedly connected at equal intervals to the outside of the drive shaft 29. The inner wall of the internally threaded cylinder 221 is threaded with a threaded rod 223. This connection method facilitates the installation and disassembly of the brushing component. A rotatable brushing roller 222 is provided at the end of the threaded rod 223 away from the internally threaded cylinder 221.

[0029] Specifically, a connecting block 224 is fixedly connected to the end of the threaded rod 223 away from the inner threaded cylinder 221. A spring 225 is fixedly connected to the side of the connecting block 224 away from the threaded rod 223. A U-shaped frame 227 is fixedly connected to the end of the spring 225 away from the connecting block 224. Two symmetrically distributed limiting rods 228 are fixedly connected to the outside of the U-shaped frame 227. Two through holes are opened on the outside of the connecting block 224. The end of the limiting rod 228 away from the U-shaped frame 227 passes through the through hole and is slidably connected to the inner wall of the through hole. Under the action of the spring 225, the brush roller 222 can be buffered so that it can adapt to the slight unevenness of the conveyor belt surface.

[0030] This design allows the U-shaped frame 227 and the brush roller 222 to elastically extend and retract slightly along the direction of the limiting rod 228 under the action of the spring 225. This ensures that the brush roller 222 maintains a continuous and gentle contact pressure on the surface of the conveyor belt 1, while preventing the U-shaped frame 227 from rotating uncontrollably.

[0031] The inner wall of the brush roller 222 is fixedly connected to the mounting shaft 226, which is rotatably connected to the inner wall of the U-shaped frame 227 via bearings, thereby ensuring that the brush roller 222 can roll smoothly when subjected to friction.

[0032] Specifically, the brush roller 222 is made of food-grade silicone, a material that is not only soft and durable and can effectively scrape off residues, but also meets food safety contact standards and will not introduce secondary contamination.

[0033] The remaining structure is the same as that in Example 1.

[0034] The workflow of this utility model is as follows: When it is necessary to sample allergens on the conveyor belt, the cylinder 23 retracts and drives the top plate 21 to move downward, thereby driving the drive motor 25 and the transmission shaft 29 below the top plate 21 to move downward, so that the outer side of the brush roller 222 contacts the conveyor belt. The brush roller 222 rolls on the conveyor belt to sample allergens on the conveyor belt. After sampling, the cylinder 23 extends and pushes the top plate 21 to move upward, completing a single allergen sampling. After a single sampling is completed, the drive motor 25 drives the transmission shaft 29 to rotate 90 degrees through the output shaft. The rotation of the transmission shaft 29 drives the brush assembly 22 after sampling to rotate 90 degrees, moving the next set of brush assemblies 22 above the sampling area. The cylinder 23 retracts, causing the brush assembly 22 above the sampling area to move downwards, and the conveyor belt is sampled for allergens again. Repeat the above operation, and use the brush wiping assembly 22 to sample the conveyor belt in turn. After multiple sets of brush wiping assemblies 22 have been sampled, the servo motor 27 drives the drive motor 25 and the transmission shaft 29 to rotate, move it outside the sampling area, remove the sampled brush wiping roller 222, and send it to the laboratory for testing.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
