Technical Field

[0001] The invention relates to the technical field of flour sampling, in particular to a flour sampling mechanism for flour production equipment. Background Art

[0002] In the flour production process, it is crucial to conduct accurate and comprehensive sampling and analysis of flour. By obtaining representative flour samples, various indicators such as moisture content, protein content, ash content, and quality characteristics at different depths (such as humidity, particle size, impurity content, etc.) can be tested, thereby controlling the quality of flour production, ensuring that flour products put on the market meet the corresponding standards, and safeguarding the company's good reputation and market competitiveness. In order to achieve accurate sampling, it is necessary to use a professional sampling agency to complete the relevant operations, and the agency must be able to adapt to different flour storage and production conditions.

[0003] At present, there are some sampling devices for flour production equipment on the market. These devices generally collect flour in the flour collection box, which can complete the flour collection work to a certain extent.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Please see attached Figure 1 -Attached Fig.10The embodiment of the present invention provides a flour sampling mechanism for flour production equipment, including a connecting tube 1. A fixing mechanism 2 is provided on the top of the connecting tube 1, which is reliably fixed on a flour collection box or a flour collection box, etc., to ensure that the sampling operation can be carried out in a stable state, and to ensure the accuracy and reliability of the sampling. A distance adjustment mechanism 3 is provided inside the connecting tube 1. In flour production, the flour may be in different height levels or different stacking states. The distance adjustment mechanism 3 is provided inside the connecting tube 1, and can flexibly change the height position relationship of the components such as the quantitative sampling mechanism 4 and the depth sampling mechanism 5 connected thereto relative to the flour according to the specific position of the actual flour. A quantitative sampling mechanism 4 is provided at the bottom of the distance adjustment mechanism 3, which accurately adjusts the size of the space inside the sampling tube that can accommodate flour, so as to achieve the purpose of quantitatively obtaining flour. Depth sampling mechanisms 5 are provided on both sides of the outside of the quantitative sampling mechanism 4. During the storage or production process, the quality characteristics (such as humidity, particle size, impurity content, etc.) of the flour at different depth levels may be different. The depth sampling mechanism 5 is arranged on both sides of the outside of the quantitative sampling mechanism 4, and can take samples from multiple different depths at the same time, comprehensively covering different positions of the flour in the vertical direction, which helps to grasp the quality distribution of flour in the entire depth range in a more detailed and complete manner, and provide multi-dimensional data support for accurately controlling the quality of flour production.

[0033] The quantitative sampling mechanism 4 includes a connecting shell 401, which serves as the basic framework of the quantitative sampling mechanism 4 and provides a relatively stable installation and bearing space for each internal component. It enables key components such as gears 402, a connecting plate 405, and a sampling tube 406 to be assembled in a specific position and manner. The inner wall of the connecting shell 401 is rotatably connected to two gears 402, and the meshing connection between the two gears 402 and the toothed plate 404 enables the telescopic movement of the multi-stage telescopic rod 403 in the distance adjustment mechanism 3 to be effectively transmitted to the gears 402 and converted into the rotational movement of the gears 402. The two gears 402 are fixedly connected to the side away from each other with a connecting plate 405, and the connecting plate 405 serves as an intermediate connecting piece to smoothly transmit the rotational movement of the gears 402 to the sampling tube 406. The two connecting plates 405 are fixedly connected to the sampling barrel 1 406 at the ends close to each other, and the two sampling barrels 1 406 are rotatably connected to the ends far away from each other with adjusting bolts 407. One end is connected to the gear 402 through the connecting plate 405, so that the sampling barrel 1 406 can rotate under the drive of the gear 402 and participate in the entire sampling process; the other end is rotatably connected to the adjusting bolt 407, which lays the foundation for the subsequent adjustment of the screw 407 and the threaded barrel 408 to change the internal space size of the sampling barrel 1 406, and finally realize the quantitative sampling function. The outer side of the adjusting bolt 407 is threadedly connected to the threaded barrel 408, and the end of the threaded barrel 408 far away from the adjusting bolt 407 is fixedly connected to the moving plate 409, so that when the adjusting bolt 407 rotates relative to the threaded barrel 408, the threaded barrel 408 will drive the moving plate 409 to move, thereby changing the internal space size of the sampling barrel 1 406. A limit assembly is provided on the outer side of the threaded barrel 408, and the limit assembly is used to limit the threaded barrel 408 when it moves. A multi-stage telescopic rod 403 is installed on the inner wall of the distance adjustment mechanism 3, and a tooth plate 404 is fixedly connected to the bottom of the multi-stage telescopic rod 403. The outer side of the tooth plate 404 is meshed with the outer side of the gear 402 to adjust the movement of the tooth plate 404, thereby indirectly controlling the rotation of the gear 402 and the subsequent movement of the sampling barrel 406.

[0034] Please see attached Figure 5 The limiting assembly includes a limiting rod 4010, one end of which is fixedly connected to the outer side of the threaded barrel 408, and a limiting groove 4011 is provided on the inner wall of the sampling barrel 406. The outer side of the limiting rod 4010 is slidably connected to the inner wall of the limiting groove 4011. The limiting rod 4010 can only slide along the inner wall of the limiting groove 4011, which ensures that the threaded barrel 408 moves in a straight line, so that when it drives the moving plate 409 to change the size of the internal space of the sampling barrel 406, the movement is more precise and stable, thereby realizing precise control of the flour sampling amount and improving the accuracy of quantitative sampling.

[0035] Please see attached Figure 1 , Attachment Figure 2, Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 and attached Fig. 9The depth sampling mechanism 5 includes a sampling barrel 502 and an adjusting rod 504. The adjusting rod 504 is arranged inside the sampling barrel 502. The sampling barrel 502 is a key component for accommodating flour samples. It cooperates with the adjusting rod 504 arranged inside it to form the core structure of the depth sampling. The adjusting rod 504 can adjust the position inside the sampling barrel 502. The top of the adjusting rod 504 is fixedly connected with a handle 503, which is convenient for the operator to directly hold and operate the adjusting rod 504 with his hands. The outer side of the adjusting rod 504 is provided with a scale mark 505, which clearly indicates the position information of the adjusting rod 504 in the sampling barrel 502. By observing the scale, the operator can accurately grasp the moving distance of the adjusting rod 504, and then accurately control the sampling depth. Two connecting rods 5017 are fixedly connected to the outside of the adjusting rod 504, and the ends of the two connecting rods 5017 that are far away are fixedly connected with a push plate 506. The connecting rod 5017 serves as an intermediate connecting piece, which converts the movement of the adjusting rod 504 into the synchronous movement of the push plate 506, and can stably and effectively transmit the movement and force of the adjusting rod 504 to the push plate 506. The outside of the push plate 506 fits the inner wall of the sampling barrel 2 502, and the push plate 506 fits tightly with the inner wall of the sampling barrel 2 502, so that the extrusion force applied by the push plate 506 to the baffle 508 in the sampling assembly can be uniform during the movement. A plurality of injection ports 507 are provided on the outside of the sampling barrel 2 502, and the plurality of injection ports 507 are distributed on the outside of the sampling barrel 2 502, so that flour can be allowed to enter the inside of the sampling barrel 2 502 at different positions at the same time, thereby increasing the injection volume per unit time and improving the sampling efficiency. A sampling assembly is provided on the inner wall of the second sampling barrel 502 near the sampling port 507. The sampling assembly is used for opening the sampling port 507. The sampling assembly includes a fixed block 5011. The outer side of the fixed block 5011 is fixedly connected to the inner wall of the second sampling barrel 502. The fixed block 5011 provides a fixing point for the return spring 5013 and the guide rod 5012. The return spring 5013 is fixedly connected to one side of the fixed block 5011. One end of the return spring 5013 is fixedly connected to a baffle 508. One end of the return spring 5013 is connected to the fixed block 5011, and the other end is connected to the baffle 508. In a natural state, the baffle 508 can be kept in a position to close the sampling port 507 by its own elastic force. In this way, flour can be effectively prevented from accidentally entering the second sampling barrel 502 when sampling is not required, thereby ensuring the controllability of the sampling operation. When pressed by the push plate 506, the spring can be compressed, allowing the baffle 508 to move so as to open the injection port 507 for sampling. After the sampling is completed, the baffle 508 can be pushed back by the elastic force to close the injection port 507 again. The baffle 508 is a component that directly blocks the injection port 507, and the change of its position determines the opening and closing state of the injection port 507.A guide component 1 is provided on the outer side of the baffle 508, and the guide component 1 is used to guide the baffle 508 when it moves. A guide component 2 is provided on the inner wall of the baffle 508, and the guide component 2 is used to guide the baffle 508 when it moves. An installation component is provided on the outer side of the sampling tube 502, and the installation component is used to install the sampling tube 502.

[0036] Please see attached Figure 8 -Attached Fig. 9 The guide assembly 1 includes a guide plate 509, the outer side of the guide plate 509 is fixedly connected to the outer side of the baffle 508, and the inner wall of the sampling tube 2 502 is provided with a guide groove 1 5010, and the inner side of the guide plate 509 is slidably connected to the inner wall of the guide groove 1 5010. When the baffle 508 is squeezed by the push plate 506 or resets and moves under the elastic force of the reset spring 5013, it can only slide along the direction specified by the guide groove 1 5010, avoiding lateral deviation and skewness of the baffle 508, thereby ensuring that the opening and closing operation of the baffle 508 on the injection port 507 can be carried out accurately, thereby improving the accuracy of the injection process.

[0037] Please see attached Figure 8 -Attached Fig. 9 The guide component 2 includes a guide rod 5012, one end of which is fixedly connected to the outer side of the fixed block 5011, and a guide groove 2 5014 is provided on the inner wall of the baffle 508. The outer side of the return spring 5013 is slidably connected to the inner wall of the guide groove 2 5014. Whether it is the process of opening the injection port 507 under the pressure of the push plate 506, or the process of closing the injection port 507 driven by the return spring 5013, it can move stably and smoothly along the prescribed longitudinal trajectory under the guidance of the guide rod 5012 and the guide groove 2 5014.

[0038] Please see attached Figure 1 -Attached Figure 6 The mounting assembly includes a mounting plate 501 and a mounting shell 5015. The outer side of the mounting plate 501 is fixedly connected to the outer side of the sampling tube 502. The outer side of the mounting shell 5015 is fixedly connected to the outer side of the connecting shell 401. The mounting plate 501 is connected to the mounting shell 5015 through a fastener 5016. The fastener 5016 is a bolt or a thread. The mounting plate 501 connects the sampling tube 502 and the mounting shell 5015. The mounting plate 501 is respectively fixed to the sampling tube 502 and the connecting shell 401 through the outer side, and then fastened with the fastener 5016 to form a stable connection structure. The stable installation enables the sampling tube 502 to be accurately in the predetermined position each time a depth sampling is performed.

[0039] Please see attached Figure 1 -Attached Fig.10The fixing mechanism 2 includes a positioning plate 201, the bottom of which is fixedly connected to the top of the connecting tube 1, providing a fixing point for the connecting tube 1. Both sides of the interior of the positioning plate 201 are slidably connected with an extension plate 203, which is connected to the positioning plate 201 through a fastener 202. The position adjustment can be achieved through the fastener 202, and the lateral coverage of the fixing mechanism 2 can be changed by sliding the extension plate 203, thereby improving the versatility and adaptability of the entire sampling mechanism to a variety of devices. One end of the bottom of the extension plate 203 is fixedly connected with a connecting plate 204, providing a use position for a fastening bolt 205. The internal thread of the connecting plate 204 is connected with a fastening bolt 205, and one end of the fastening bolt 205 is rotatably connected with a fixing plate 206. When the fastening bolt 205 is rotated, the power of its rotation can be directly and effectively transmitted to the fixing plate 206, driving the fixing plate 206 to move. A second fixing plate 208 is fixedly connected to one side of the bottom of the extension plate 203, and together with the first fixing plate 206 movable by the fastening bolts 205, they form a structure capable of clamping the edge of the flour production equipment.

[0040] Please refer to the attached Fig.10 A rubber pad 1 207 is provided on one side of the fixing plate 1 206 close to the fixing plate 2 208, and a rubber pad 209 is provided on one side of the fixing plate 208 close to the fixing plate 1 206. When the fixing plate 1 206 is moved toward the fixing plate 2 208 and the edge of the flour production equipment is clamped by tightening the bolts 205, the rubber pad 1 207 and the rubber pad 2 209 will be squeezed and deformed. The rubber material itself has a large friction coefficient, and this deformation significantly increases the friction between the rubber pad and the flour collection box and between the two pads.

[0041] Please refer to the attached Figure 3 -Attached Figure 4The distance adjustment mechanism 3 includes an adjustment cylinder 301, the outer side of which is slidably connected to the inner wall of the connection cylinder 1. During the flour sampling process, the adjustment cylinder 301 can be easily changed according to different situations such as the actual stacking height of the flour and the sampling position requirements, through this sliding connection method, so as to flexibly adjust the relative position relationship between the sampling component and the flour, ensure that the sampling can be accurately performed from the appropriate position, and improve the accuracy and flexibility of sampling. The inner wall of the adjustment cylinder 301 is fixedly connected to a fixed cylinder 302, and the inner wall of the fixed cylinder 302 is fixedly connected to a compression spring 303, one end of the compression spring 303 is fixedly connected to a movable plate 304, and the end of the movable plate 304 away from the compression spring 303 is fixedly connected to a clamping column 305, and the fixed cylinder 302 provides an installation base for the compression spring 303. When the distance needs to be adjusted, the clamping column 305 can be disengaged from the clamping slot 306 by external force, at which time the compression spring 303 is compressed, and the adjusting cylinder 301 can slide freely to adjust the position; and when it is adjusted to the appropriate position, the external force is released, and the compression spring 303 pushes the movable plate 304 by its own elastic restoring force, driving the clamping column 305 to accurately insert into the corresponding clamping slot 306, so as to fix the position of the adjusting cylinder 301. Multiple clamping slots 306 are equidistantly provided on the outside of the connecting cylinder 1, and the clamping column 305 is plugged into and matched with the clamping slots 306. The clamping column 305 is plugged into and matched with multiple clamping slots 306 equidistantly provided on the outside of the connecting cylinder 1. When the clamping column 305 is inserted into different clamping slots 306, the adjusting cylinder 301 can be accurately fixed at different vertical positions. This plug-in matching method provides a simple and effective positioning means, which can accurately select the appropriate card slot 306 to fix the position of the adjustment cylinder 301 according to the specific sampling requirements, so that the relative position between the sampling component and the flour can be set as expected, further improving the accuracy of the sampling position adjustment, and helping to obtain a more representative flour sample. The bottom of the adjustment cylinder 301 is fixedly connected to the top of the connecting shell 401, and when the adjustment cylinder 301 moves, it drives the connecting shell 401 to move. The inner wall of the adjustment cylinder 301 is fixedly connected to the outer side of the multi-stage telescopic rod 403, providing an installation position for the multi-stage telescopic rod 403.

[0042] Working principle: First, move the extension plate 203 to a suitable position and fix it with a fastener 202, then adjust the height of the adjustment cylinder 301 according to the height of the flour in the flour collection box, and manually apply external force to the clamping column 305, so that the clamping column 305 overcomes the elastic force of the compression spring 303 and disengages from the clamping groove 306 on the outside of the connecting cylinder 1. At this time, the adjustment cylinder 301 can slide up and down freely along the inner wall of the connecting cylinder 1 to change its position relative to other components. After adjusting to a suitable position, release the clamping column 305, and the compression spring 303 relies on its own elastic restoring force to push the movable plate 304 to drive the clamping column 305, so that the clamping column 305 is accurately inserted into the corresponding clamping groove 306, thereby fixing the position of the adjustment cylinder 301. When the position of the adjustment cylinder 301 is adjusted.

[0043] First, according to the amount of flour to be taken, the adjusting bolt 407 is turned, and the adjusting bolt 407 drives the threaded barrel 408 to move. The limiting rod 4010 on the outside of the threaded barrel 408 slides in the limiting groove 4011 to provide a guide limit for the threaded barrel 408 during the movement. When the threaded barrel 408 moves, it drives the moving plate 409 to move, thereby changing the size of the space inside the sampling barrel 406. After the moving plate 409 is adjusted to the position of the sampling barrel 406, the multi-stage telescopic rod 403 is started, and the multi-stage telescopic rod 403 drives the tooth plate 404 to move downward. The movement of the tooth plate 404 drives the gear 402 to rotate on the inner wall of the connecting shell 401. The connecting plate 405 fixed on one side of the gear 402 will rotate synchronously with the rotation of the gear 402, thereby driving the sampling barrel 406 to rotate together. After the position of the sampling barrel 406 is adjusted, the multi-stage telescopic rod 403 drives the tooth plate 404 to move downward. The movement of the tooth plate 404 drives the gear 402 to rotate on the inner wall of the connecting shell 401. The connecting plate 405 fixed on one side of the gear 402 will rotate synchronously with the rotation of the gear 402, thereby driving the sampling barrel 406 to rotate together. Then, fix plate 208 between fix plate 1 206 is clamped on the edge of the flour collecting box, and the fastening bolt 205 is turned to make fix plate 1 206 move toward fix plate 208. In this process, rubber pad 1 207 on one side of fix plate 1 206 and rubber pad 2 209 on one side of fix plate 208 are squeezed and fitted with each other, and clamped on the edge of the flour collecting box, so that they are firmly fixed on the flour collecting box, which can ensure that the positioning plate 201 is firmly fixed on the collection box and is not prone to loosening or displacement, thereby ensuring that the subsequent sampling work can be carried out stably and accurately.

[0044] At this time, the sampling tube 406 is inserted into the flour, and then the multi-stage telescopic rod 403 is started to retract, driving the tooth plate 404 to move, driving the gear 402 to rotate, so that the two sampling tubes 406 are driven to close, and the flour is poured into the sampling tube 406, so as to achieve the purpose of quantitative sampling of the flour, and can ensure that the amount of flour sample obtained each time is relatively accurate and stable, which is convenient for the subsequent accurate detection and analysis of various indicators of flour, and reduces the detection error that may be caused by inconsistent sampling amount.

[0045] When it is necessary to take flour of different depths, the sampling tube 502 is inserted into the mounting shell 5015 through the mounting plate 501 on the outside thereof, and then the sampling tube 502 is fixed by the fastener 5016 and firmly mounted on the outside of the connecting shell 401 to ensure that its position is stable and reliable during the sampling process. As described above, after adjusting the adjustment tube 301 and fixing the positioning plate 201 on the edge of the flour collection box, the operator then holds the handle 503 to operate the adjustment rod 504. By observing the scale mark 505 on the outside of the adjustment rod 504, the moving distance of the adjustment rod 504 inside the sampling tube 502 can be accurately controlled. When the adjustment rod 504 moves, the two connecting rods 5017 fixed on the outside thereof will also move synchronously. The connecting rod 5017 fixes the push plate 506, which will slide along the inner wall of the sampling tube 502. When the push plate 506 slides upward to a suitable position and is flush with the corresponding baffle 508, the handle 503 is then turned to push the plate 506. 506 rotates accordingly, and the push plate 506 is arc-shaped, squeezing the baffle 508. After the baffle 508 is squeezed, the guide groove 2 5014 slides on the outside of the guide rod 5012, and the baffle 508 squeezes the return spring 5013. At the same time, the baffle 508 drives the guide plate 509 to slide in the guide groove 1 5010. The baffle 508 moves and then opens the sampling port 507. Because the push plate 506 is smaller than the sampling port 507, the flour enters the sampling tube 2 502, and the flour samples are accurately obtained from different depths according to actual needs, which is helpful to fully understand the quality of flour at different depths, etc., and provide more detailed and accurate data support for flour production quality control.
