Description

Technical Field

[0001] This invention relates to the field of material sampling technology, specifically to a sampling device for the mixing uniformity of a horizontal mixer. Background Technology

[0002] Currently, horizontal mixers are widely used in many industries such as chemical, building materials, food, and feed as core equipment for mixing and processing powder and granular materials. The uniformity of material mixing is a key indicator that directly determines the quality of the finished product. Therefore, accurate sampling and testing of materials in different areas inside the mixing cylinder has become an important process for controlling the mixing quality.

[0003] A search revealed that patent CN211800265U discloses a mixer for uniformly mixing and sampling raw materials. This mixer relies on a straight-tube sampling rod inserted to a specified depth inside the mixing cylinder to extract materials at single points and within a small area. However, it can only obtain a small amount of material samples from localized locations, resulting in narrow sampling coverage and extremely poor sample representativeness. This makes it difficult to comprehensively reflect the actual mixing state of the materials inside the mixing cylinder. The uniformity test results obtained based on such samples have significant errors and cannot accurately determine the overall mixing effect. Furthermore, this equipment essentially lacks the function of zoned sampling, failing to separate and independently collect materials from different vertical height areas inside the mixing cylinder. It can only collect materials from different layers together, making it impossible to achieve layered traceability testing and intuitively determine the mixing differences between upper and lower layers of material. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a horizontal mixer mixing uniformity sampling device, which improves the accuracy of post-sampling detection by continuously sampling at different heights and storing samples in sections.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a horizontal mixer mixing uniformity sampling device, comprising:

[0006] Base;

[0007] A mixing cylinder is disposed on the base, and the mixing cylinder is provided with at least one sampling channel with an opening facing downward.

[0008] A sampling component disposed on the base, the sampling component comprising:

[0009] A base is mounted on the base;

[0010] A switching disk is rotatably mounted on the base. At least two sampling cylinders are mounted on the switching disk. The switching disk is adapted to be driven to rotate so that the sampling cylinders are in a sampling position or a preparation position. The sampling cylinders in the sampling position are located below the sampling channel.

[0011] A rotating mechanism is provided on the base, and the rotating mechanism is connected to the switching disk to drive the switching disk to rotate.

[0012] A lifting assembly mounted on the base is adapted to move the sampling cylinder located at the sampling station vertically, thereby allowing the sampling cylinder to pass through the corresponding sampling channel and partially enter the mixing cylinder, wherein:

[0013] The sampling tube is provided with multiple partition plates at intervals, and sampling chambers are formed between adjacent partition plates. Sampling ports that communicate with the corresponding sampling chambers are opened on the outer wall of the sampling tube. The sampling chambers corresponding to different sampling tubes are of different sizes.

[0014] Furthermore, in order to drive the sampling cylinder into the mixing cylinder for sampling, the lifting assembly includes a lifting mechanism and a clamping mechanism. The lifting mechanism is disposed on the base, and the clamping mechanism is used to clamp the sampling cylinder located at the sampling station. The lifting mechanism is connected to the clamping mechanism to drive the clamping mechanism to move linearly in the vertical direction.

[0015] Furthermore, in order to enable the sampling cylinder to extend into the sampling channel at different positions, the base is slidably disposed on the base along the axial direction of the mixing cylinder, and the base is provided with a sliding mechanism connected to the base.

[0016] Furthermore, to enable the sampling cylinder to be inserted into the designated position of the material for sampling, the horizontal mixer mixing uniformity sampling device also includes a switching assembly, which includes:

[0017] A switch element corresponding to the sampling port on the sampling chamber is provided with a feeding channel for connecting the external space of the sampling cylinder and the corresponding sampling chamber. The switch element is slidably disposed in the corresponding sampling chamber. The switch element has an open position and a closed position. When the switch element is in the closed position, the switch element is located in the corresponding sampling port, so that the feeding channel is located in the sampling chamber. When the switch element is moved to the open position, part of the switch element extends out of the corresponding sampling port, so that the inlet of the feeding channel is located outside the sampling cylinder.

[0018] A pushing component, the pushing component being adapted to push the switch element from the closed position to the open position;

[0019] An elastic component is provided, which is connected to the switch and the partition plate near the sampling port. The elastic component is adapted to drive the switch from the open position to the closed position.

[0020] Furthermore, in order to enable the material to flow into the sampling chamber on its own, the inlet of the feed channel faces upward.

[0021] Furthermore, to prevent materials from affecting the pushing component, a baffle is provided between two adjacent partition plates. The baffle, together with the corresponding two partition plates and the inner wall of the sampling cylinder, forms the sampling chamber, and the pushing component is located outside the sampling chamber.

[0022] Furthermore, in order to enable multiple sampling chambers to sample layer by layer from top to bottom, the pushing component includes:

[0023] A pusher is slidably disposed on the sampling cylinder along the axial direction of the sampling cylinder. The pusher has an upper position and a lower position. The pusher is adapted to be moved from the upper position to the lower position, and then sequentially contacts the switch on the moving path from top to bottom.

[0024] A pushing mechanism is provided on the sampling cylinder, and the pushing mechanism is connected to the pushing member to drive the pushing member to move linearly.

[0025] Furthermore, to prevent material leakage or flow after the sampling chamber is opened, the horizontal mixer's mixing uniformity sampling device also includes a sealing component, which includes:

[0026] A plug is movable on the mixing cylinder, and a contact portion is provided at one end of the plug near the inner cavity of the mixing cylinder;

[0027] A limiting component is provided on the mixing cylinder. The limiting component has a limiting locked state and a limiting released state. When the limiting component is in the limiting locked state, the plug is limited in the sampling channel. When the limiting component is in the limiting released state, the constraint on the plug is released.

[0028] A docking mechanism is provided between the sampling cylinder and the plug, the docking mechanism being adapted to dock the two when the sampling cylinder comes into contact with the plug.

[0029] Furthermore, the contact portion is an arc shape that protrudes towards the inner cavity of the mixing cylinder.

[0030] Furthermore, the contact portion is an arc shape with the same curvature as the inner wall of the mixing cylinder.

[0031] By adopting the above technical solution, the present invention has the following beneficial effects:

[0032] To improve the uniformity detection accuracy, multiple sampling cylinders are installed. These cylinders are all the same size, but differ in the spacing between the partition plates, creating sampling chambers of varying sizes. All sampling chambers within the same cylinder are identical in size. When the sampling cylinders penetrate the material layer to the same depth, using a cylinder with a smaller sampling chamber allows for the division of the material along the movement path into more sections for sampling and collection. This better reflects the mixing uniformity of the material at different heights during subsequent testing. When the material layer is relatively low within the mixing cylinder, the sampling cylinder only needs to penetrate a shorter distance. In this case, using a sampling cylinder with a smaller sampling chamber allows for more detailed division and separate sampling within a limited insertion range. A rotating mechanism drives a switching plate, moving the corresponding sampling cylinder to the sampling position according to the required sampling accuracy. The cylinder is then extended into the mixing cylinder for sampling via a lifting component. Attached Figure Description

[0052] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0053] Example 1: As Figure 1-3 As shown, a horizontal mixer mixing uniformity sampling device includes:

[0054] Base 1;

[0055] A mixing cylinder 11 is provided on the base 1, and the mixing cylinder 11 is provided with at least one sampling channel 12 with the opening facing downward;

[0056] A sampling component is disposed on the base 1, the sampling component including:

[0057] Base 2 is mounted on base 1;

[0058] Rotate the switching disk 21 set on the base 2. At least two sampling cylinders 22 are provided on the switching disk 21. The switching disk 21 is adapted to be driven to rotate so that the sampling cylinders 22 are in the sampling position or the preparation position. The sampling cylinders 22 in the sampling position are located below the sampling channel 12.

[0059] A rotating mechanism 23 is provided on the base 2, and the rotating mechanism 23 is connected to the switching disk 21 to drive the switching disk 21 to rotate;

[0060] A lifting assembly 24 is mounted on the base 2. The lifting assembly 24 is adapted to move the sampling cylinder 22 located in the sampling station in the vertical direction, thereby causing the sampling cylinder 22 to pass through the corresponding sampling channel 12 and partially enter the mixing cylinder 11, wherein:

[0061] Multiple partition plates 3 are spaced apart inside the sampling tube 22, and sampling chambers 31 are formed between adjacent partition plates 3. Sampling ports 32 connected to the corresponding sampling chambers 31 are opened on the outer wall of the sampling tube 22. The sampling chambers 31 corresponding to different sampling tubes 22 are of different sizes.

[0062] In this embodiment, the material enters the mixing cylinder 11 for mixing. After mixing, the lifting component 24 is activated to move the sampling cylinder 22 located at the sampling station upward to pass through the sampling channel 12 and enter the mixing cylinder 11. The sampling cylinder 22 passes through the material layer in the mixing cylinder 11. When it reaches the specified depth, the material at the sampling cylinder 22 is sampled through the sampling port 32, and the material at different heights is collected in multiple sampling chambers 31. The material samples in the sampling chambers 31 are used for subsequent uniformity detection.

[0063] Furthermore, to improve the uniformity detection accuracy, multiple sampling cylinders 22 are provided. These cylinders are all identical in size, but differ in the spacing between the partition plates 3, creating sampling chambers 31 of varying sizes. Since the sampling chambers 31 within the same sampling cylinder 22 are identical in size, when the sampling cylinders 22 extend into the material layer to the same depth, using a sampling cylinder 22 with smaller sampling chambers 31 allows for the division of the material along the movement path into more sections for sampling and collection. This enables better performance in subsequent testing. To reflect the uniformity of material mixing at different heights, when the material layer is low in the mixing cylinder 11, the sampling cylinder 22 only needs to extend a short distance to penetrate the material layer. At this time, the sampling cylinder 22 with a smaller sampling chamber 31 can be used to divide the material layer more finely and sample and collect it separately within a limited range. The setting of the switching disk 21 is driven by the rotating mechanism 23. The corresponding sampling cylinder 22 is moved to the sampling position according to the required sampling accuracy, and the lifting component 24 is used to extend it into the mixing cylinder 11 for sampling.

[0064] Specifically, such as Figure 4 As shown, the mixing cylinder 11 includes a cylinder body, a stirring element, and a stirring drive element that drives the stirring element to rotate. The sampling channel 12 is opened on the cylinder body. The stirring drive element drives the stirring element to rotate, thereby mixing the material in the cylinder body. This part is prior art, and its specific structure and working principle will not be described in detail here. The stirring element can be replaced according to actual needs, so that when sampling is carried out after the mixing work is stopped, it will not interfere with the inserted sampling cylinder 22.

[0065] Specifically, such as Figure 3 As shown, each sampling chamber 31 on the sampling cylinder 22 has a corresponding discharge port on its wall. The discharge port is equipped with a cover plate 33. After sampling is completed, the sampling cylinder 22 is moved to the outside of the mixing cylinder 11. The cover plate 33 is removed, and the internal material sample is taken out for corresponding testing. The sampling chamber 31 can also be cleaned through the discharge port.

[0066] Of course, the cover plate 33 can be made of transparent material, such as glass. With this setting, it is possible to avoid taking out the sample. Without disturbing the sample, the sample can be directly photographed by adding a visual inspection component and the uniformity can be detected through image processing.

[0067] It should be noted that the cover plate 33 can be connected to the sampling cylinder 22 by bolts or snap-fit, etc. The specific connection method is existing technology and will not be described in detail here. After the cover plate 33 is connected to the sampling cylinder 22, its outer surface must be flush with the outer wall of the sampling cylinder 22 to avoid excessive disturbance of the material during the process of the sampling cylinder 22 being inserted into the material.

[0068] Specifically, such as Figure 5 As shown, the rotating mechanism 23 includes a rotary motor 25, a drive gear 26, and a driven gear 27 meshing with the drive gear 26. The drive gear 26 is rotatably mounted on the base 2, and the driven gear 27 is fixedly sleeved on the switching disk 21. The rotary motor 25 is mounted on the base 2, and the output end of the rotary motor 25 is connected to the drive gear 26.

[0069] In this embodiment, when it is necessary to move the designated sampling cylinder 22 from the preparation station to the sampling station for sampling, the rotary motor 25 is started to drive the drive gear 26 to rotate, which in turn drives the driven gear 27 to rotate, and finally drives the switching disk 21 to rotate. When the switching disk 21 rotates, it can move the designated sampling cylinder 22 to the sampling station.

[0070] like Figure 5As shown, the lifting assembly 24 includes a lifting mechanism 28 and a clamping mechanism 29. The lifting mechanism 28 is mounted on the base 2, and the clamping mechanism 29 is used to clamp the sampling cylinder 22 located at the sampling station. The lifting mechanism 28 is connected to the clamping mechanism 29 to drive the clamping mechanism 29 to move linearly in the vertical direction.

[0071] Specifically, such as Figure 5 As shown, the clamping mechanism 29 includes a movable plate 210, two clamping plates 211, a clamping motor 212, and a bidirectional screw. The bidirectional screw is rotatably mounted on the movable plate 210 and has two oppositely arranged threads. The two clamping plates 211 are respectively mounted on the two oppositely arranged threads and are slidably mounted on the movable plate 210. The clamping motor 212 is mounted on the movable plate 210 and its output end is connected to the bidirectional screw.

[0072] It should be noted that the specific connection method between the bidirectional screw and the clamping plate 211 is existing technology, and its specific structure and working principle will not be described in detail here. Of course, the clamping mechanism 29 can directly adopt a robotic arm or the like, as long as it can clamp the sampling cylinder 22.

[0073] In this embodiment, when it is necessary to clamp the designated sampling cylinder 22, the clamping motor 212 is started to drive the bidirectional screw to rotate, which in turn drives the two clamping plates 211 to move towards each other along the axis of the bidirectional screw, thereby clamping the sampling cylinder 22. When it is necessary to release the sampling cylinder 22, the clamping motor 212 is started to drive the bidirectional screw to rotate in the opposite direction, so that the two clamping plates 211 move back to their original positions, thereby releasing the sampling cylinder 22.

[0074] Specifically, such as Figure 5 As shown, the lifting mechanism 28 includes a lifting motor 213, a first lead screw and nut pair 214, and a transmission sleeve 215. The first lead screw and nut pair 214 includes a first threaded rod rotatably mounted on the base 2 and a first nut connected to the first threaded rod. The first nut is connected to the transmission sleeve 215. The lifting motor 213 is mounted on the base 2, and the output end of the lifting motor 213 is connected to the first threaded rod. The moving plate 210 is slidably mounted on the transmission sleeve 215.

[0075] In this embodiment, when it is necessary to control the lifting of the clamped sampling cylinder 22, the lifting motor 213 is started to drive the first threaded rod to rotate, which in turn drives the transmission sleeve 215 to move linearly along the axis of the first threaded rod, thereby driving the moving plate 210 (including the entire clamping mechanism 29) to move, and finally driving the clamped sampling cylinder 22 to move linearly.

[0076] Specifically, such as Figure 5 As shown, a drive cylinder 216 is provided on the transmission sleeve 215. The extension and retraction end of the drive cylinder 216 is connected to the moving plate 210. The drive cylinder 216 can be an electric cylinder or a pneumatic cylinder, etc.

[0077] In this embodiment, to avoid positional interference of the sampling cylinder 22 during the rotation of the switching disk 21 when the clamping mechanism 29 is not clamping the sampling cylinder 22, a drive cylinder 216 is provided. When not clamping, the drive cylinder 216 drives the moving plate 210 to move away from the sampling cylinder 22. When clamping is required, the drive cylinder 216 drives the moving plate 210 to move towards the sampling cylinder 22.

[0078] like Figure 1 As shown, the base 2 is slidably mounted on the base 1 along the axial direction of the mixing cylinder 11. The base 1 is provided with a sliding mechanism 217, which is connected to the base 2.

[0079] In this embodiment, the mixing cylinder 11 is provided with multiple sampling channels 12 at intervals along its own axial direction, so that the sampling cylinder 22 can be inserted into different sampling channels 12 to take samples. By sampling the material at different positions of the mixing cylinder 11, the comprehensiveness of the sampling is improved. When it is necessary to move the sampling cylinder 22 to the corresponding sampling channel 12, the sliding mechanism 217 is activated to drive the base 2 to move, thereby driving the sampling cylinder 22 to move.

[0080] Specifically, such as Figure 1 As shown, the sliding mechanism 217 includes a sliding motor 218 and a second lead screw and nut pair 219. The second lead screw and nut pair 219 includes a second threaded rod rotatably mounted on the base 1 and a second nut connected to the second threaded rod. The second nut is mounted on the base 2. The sliding motor 218 is mounted on the base 1, and the output end of the sliding motor 218 is connected to the second lead screw.

[0081] In this embodiment, when the base 2 needs to be moved as a whole to the point where the designated sampling cylinder 22 is coaxially aligned with the selected sampling channel 12, the sliding motor 218 is started to drive the second threaded rod to rotate, thereby driving the base 2 to move along the axial direction of the second threaded rod, and thus driving the sampling cylinder 22 to move to the designated position.

[0082] Example 2: Figure 6 As shown, this embodiment further includes the following structure based on Embodiment 1: the horizontal mixer mixing uniformity sampling device also includes a switching assembly, which includes:

[0083] A switch 4 is provided corresponding to the sampling port 32 on the sampling chamber 31. The switch 4 is provided with a feeding channel 41 for connecting the external space of the sampling cylinder 22 and the corresponding sampling chamber 31. The switch 4 is slidably disposed in the corresponding sampling chamber 31. The switch 4 has an open position and a closed position. When the switch 4 is in the closed position, the switch 4 is located in the corresponding sampling port 32, so that the feeding channel 41 is located in the sampling chamber 31. When the switch 4 is moved to the open position, part of the switch 4 extends out of the corresponding sampling port 32, so that the inlet of the feeding channel 41 is located outside the sampling cylinder 22.

[0084] Pushing component 42, which is adapted to push the switch 4 from the closed position to the open position;

[0085] The elastic component 43 is connected to the switch 4 and the partition plate 3 near the sampling port 32. The elastic component 43 is adapted to drive the switch 4 from the open position to the closed position.

[0086] In this embodiment, when the sampling cylinder 22 is inserted into the mixing cylinder 11, the switch 4 is in the closed position (i.e., the initial position). Under the obstruction of the switch 4, the sampling port 32 is closed, preventing the material from entering the sampling chamber 31 prematurely before the sampling cylinder 22 has been inserted to the specified depth. When the sampling cylinder 22 is moved to the specified depth, the pushing component 42 is activated, pushing the switch 4 to the open position. At this time, the switch 4 is moved to the point where it partially extends outside the sampling cylinder 22, so that the feeding channel 41 is located outside the sampling cylinder 22, exposing the inlet of the feeding channel 41 to the material layer. At this time, the material within the range of the inlet of the feeding channel 41 can enter the feeding channel 41 through the inlet and finally flow into the sampling chamber 31 to complete the sampling work. After the sampling is completed, the pushing component 42 does not apply a pushing force to the switch 4. At this time, the switch 4 is reset to the closed position through the elastic component 43, and the feeding channel 41 is retracted into the sampling cylinder 22, ending the sampling work.

[0087] Specifically, such as Figure 6 As shown, the side of the switch 4 near the outer wall of the sampling cylinder 22 is arc-shaped. When the switch 4 is in the closed position, the arc-shaped side of the switch 4 is flush with the outer wall of the sampling cylinder 22, avoiding any protrusions on the outer wall of the switch 4. This reduces disturbance to the material layer when the sampling cylinder 22 is moved within the material layer, improves the accuracy of material sampling, and enhances the accuracy of subsequent uniformity detection.

[0088] Specifically, such as Figure 7 As shown, a slide bar 44 is provided on the switch component 4, and a slider 45 is provided on the partition plate 3 near the switch component 4. The slider 45 is slidably mounted on the slide bar 44.

[0089] The elastic component 43 is a telescopic spring, which is sleeved on the outside of the slide rod 44. The two ends of the telescopic spring are connected to the switch component 4 and the slider 45, respectively.

[0090] In this embodiment, when the switch 4 is moved by the pusher 42, the slide bar 44 slides within the slider 45. Simultaneously, as the slide bar 44 moves, the telescopic spring is stretched. When the pusher 42 stops pushing the switch 4, the telescopic spring returns from the stretched state to the natural state and drives the switch 4 to move to the reset state.

[0091] like Figure 8 As shown, the inlet of the feed channel 41 faces upwards.

[0092] In this embodiment, the opening of the feed channel 41 faces upward and extends to the outside of the sampling cylinder 22 to directly contact the material. The material located above the opening of the feed channel 41 can flow through the feed channel 41 by its own gravity and enter the corresponding sampling chamber 31. The sampling is carried out by the flow of the material itself, avoiding the application of external force. For example, negative pressure extraction will cause the original mixing state of the material to be severely damaged, and the accuracy of uniformity detection will be reduced.

[0093] like Figure 8-9 As shown, a baffle 46 is provided between two adjacent partition plates 3. The baffle 46, the corresponding two partition plates 3, and the inner wall of the sampling cylinder 22 form a sampling chamber 31. The pushing component 42 is located outside the sampling chamber 31.

[0094] In this embodiment, the material storage range of the sampling chamber 31 is further limited. The pusher 42 is isolated outside the storage range by the baffle 46 to prevent the material from affecting the pusher 42.

[0095] like Figure 9 As shown, the actuating component 42 includes:

[0096] Pusher 47 is slidably disposed on the sampling cylinder 22 along the axial direction of the sampling cylinder 22. Pusher 47 has an upper position and a lower position. Pusher 47 is adapted to be moved from the upper position to the lower position and then contact the switch 4 on the moving path from top to bottom in sequence.

[0097] A pushing mechanism is provided on the sampling cylinder 22, which is connected to the pushing component 47 to drive the pushing component 47 to move linearly.

[0098] In this embodiment, to ensure that multiple sampling chambers 31 open sequentially from top to bottom and sample materials at corresponding material layer heights, effectively preventing mixing and cross-convection of materials at different height levels during sampling, and ensuring that only pure material samples of the corresponding height range remain in each chamber, a pushing component 47 is provided. Driven by a pushing mechanism, the pushing component 47 moves from a top position to a bottom position, sequentially contacting and pushing the contacting switch 4 along the moving path. The specific process is as follows: When the pushing component 47 is in the top position (i.e., the initial position), it does not contact any switch 4. When the sampling cylinder 22 moves to the specified depth, the sampling process begins. The pushing mechanism is activated to move the pushing component 47. The pushing component 47 first contacts the uppermost switch 4 and pushes it to move, opening the feed channel 41 corresponding to that switch 4 for sampling. The sampling chamber 31 corresponding to that switch 4 is in a state of continuous material sampling. When sampling is completed, the pushing mechanism stops working, keeping the pushing component 47 in contact with the switch component 4 to prevent the feeding channel 41 from being closed prematurely before sampling is completed. When the sampling chamber 31 completes the sampling work, the pushing mechanism starts, driving the pushing component 47 to continue moving downward. At this time, the pushing component 47 loses contact with the switch component 4 corresponding to the sampling chamber 31 that has completed the sampling work. The switch component 4 is reset to the closed position through the elastic component 43, ending the sampling work. Subsequently, the pushing component 47 continues to move and contacts the next switch component 4, repeating the above steps. This allows different sampling chambers 31 to be opened sequentially from top to bottom for sampling work, and each sampling chamber 31 is automatically closed after sampling is completed, achieving the effect that only one sampling chamber 31 is opened in each sampling work. When the required sampling chamber 31 has completed sampling and the material sample in the sampling chamber 31 has been tested accordingly, the pushing component 47 is reset to the upper position under the drive of the pushing mechanism, ready for the next round of sampling work.

[0099] Specifically, such as Figure 10 As shown, the pusher 47 is provided with an inclined portion 410, and the switch 4 is provided with an arc-shaped portion 411 that cooperates with the inclined portion 410 on the side near the pusher 47. When the pusher 47 is moved to contact the switch 4, the inclined portion 410 contacts the arc-shaped portion 411 and squeezes the arc-shaped portion 411 through the inclined portion 410, causing the switch 4 to move.

[0100] Specifically, such as Figure 10 As shown, the pusher 47 is provided with a positioning part 412. When the pusher mechanism stops working and the pusher 47 keeps in contact with the corresponding switch 4, the positioning part 412 of the pusher 47 abuts against the arc-shaped part 411 of the switch 4, so that the feed channel 41 remains open.

[0101] Specifically, such as Figure 9-10As shown, the pushing mechanism includes a pushing motor 48 and a third lead screw and nut assembly 49. The third lead screw and nut assembly 49 includes a third threaded rod rotatably mounted on the sampling cylinder 22 and a third nut connected to the third threaded rod. The third nut is mounted on the pushing member 47. The pushing motor 48 is mounted on the sampling cylinder 22, and the output end of the pushing motor 48 is connected to the third lead screw.

[0102] In this embodiment, when the pusher 47 needs to move, the push motor 48 is activated to drive the third threaded rod to rotate, thereby causing the pusher 47 to move along the axial direction of the third threaded rod.

[0103] Example 3: Figure 11-12 As shown, this embodiment further includes the following structure based on Embodiment 1: the horizontal mixer mixing uniformity sampling device also includes a sealing component, which includes:

[0104] The plug 5 is movable on the mixing cylinder 11, and a contact part 51 is provided at one end of the plug 5 near the inner cavity of the mixing cylinder 11;

[0105] A limiting component 52 is provided on the mixing cylinder 11. The limiting component 52 has a limiting locked state and a limiting released state. When the limiting component 52 is in the limiting locked state, the plug 5 is limited in the sampling channel 12. When the limiting component 52 is in the limiting released state, the constraint on the plug 5 is released.

[0106] A docking mechanism 53 is provided between the sampling cylinder 22 and the plug 5. The docking mechanism 53 is adapted to dock the sampling cylinder 22 and the plug 5 when they come into contact.

[0107] In this embodiment, when the plug 5 is in its initial position (i.e., within the sampling channel 12), the passage between the inner cavity of the mixing cylinder 11 and the outside is sealed, and the material being mixed inside will not leak out. During the sampling process, the sampling cylinder 22 is moved towards the sampling channel 12. During this movement, the top of the sampling cylinder 22 contacts the bottom of the plug 5 and is connected as a whole through the docking mechanism 53. After docking, the limiting component 52 switches to the released limiting state, releasing the positional constraint on the plug 5. As the sampling cylinder 22 continues to move, it drives the plug 5 to move synchronously into the mixing cylinder 11. The contact part 51 contacts the material first. When the sampling cylinder 22 passes through the sampling channel 12, the outer wall of the sampling cylinder 22 abuts against the inner wall of the sampling channel 12, preventing material leakage. The material flows out through the gap between the two. When the sampling cylinder 22 moves to the specified depth, it stops moving and begins sampling. In this setting, the plug 5 extends into the mixing cylinder 11 along with the sampling cylinder 22. The sampling cylinder 22 then replaces the plug 5 to seal the sampling channel 12, preventing the sampling channel 12 from opening during the opening process, preventing material spillage, and also preventing material from flowing into the sampling channel 12, which would change the original mixing state and ultimately lead to distortion of the uniformity detection. After sampling is completed, the sampling cylinder 22 is passively moved to drive the plug 5 back into the sampling channel 12. At this time, the limiting component 52 is activated to limit the plug 5. As the sampling cylinder 22 continues to move to the reset position, the plug 5 is disconnected from the sampling cylinder 22.

[0108] Specifically, such as Figure 12 As shown, the limiting component 52 includes a limiting member 54 that is slidably disposed along the mixing cylinder 11 and a limiting drive member 55 disposed on the mixing cylinder 11. A limiting groove that cooperates with the limiting member 54 is provided in the plug 5. The limiting drive member 55 is connected to the limiting member 54 to drive the limiting member 54 to insert or withdraw from the limiting groove.

[0109] The limit drive component 55 can be a cylinder or an electric cylinder, etc., and its extension end is connected to the limit component 54.

[0110] In this embodiment, when the limiting component 52 switches to the limiting lock state, the limiting drive component 55 starts and drives the limiting component 54 to move into the insertion limiting groove, thereby limiting the plug 5 in the sampling channel 12 to block the sampling channel 12. When the limiting component 52 switches to the releasing limiting state, the limiting drive component 55 starts and drives the limiting component 54 to be pulled out of the limiting groove range, so that the plug 5 can be inserted into the mixing cylinder 11 together with the sampling cylinder 22.

[0111] Specifically, such as Figure 12 As shown, the plug 5 is provided with a sealing plate 56 and a reset assembly 57. The sealing plate 56 is slidably disposed in the plug 5 and is adapted to be moved to open or close the limiting groove.

[0112] The reset assembly 57 includes a telescopic rod and a reset spring. The two ends of the telescopic rod are connected to the sealing plate 56 and the limiting groove wall, respectively. The reset spring is sleeved on the outside of the telescopic rod, and the two ends of the reset spring are connected to the sealing plate 56 and the limiting groove wall, respectively.

[0113] In this embodiment, the sealing plate 56 is in the initial position, the limiting member 54 is not inserted into the limiting groove, the sealing plate 56 closes the limiting groove, the outer wall of the sealing plate 56 is aligned with the outer wall of the sampling cylinder 22 to reduce disturbance to the material, and the return spring is in the natural state. When the limiting member 54 is moved to be inserted into the limiting groove, the limiting member 54 pushes the sealing plate 56 to move, the return spring is compressed, and the plug 5 is restricted within the sampling channel 12.

[0114] Specifically, such as Figure 13-14 As shown, the docking mechanism 53 includes a docking block 58 disposed on the plug 5 and a docking groove 59 disposed on the sampling cylinder 22. Both the docking block 58 and the docking groove 59 are provided with magnetic attraction parts. When the sampling cylinder 22 is moved upward to the docking block 58 inserted into the docking groove 59, the two magnetic attraction parts attract each other, thereby realizing the docking of the plug 5 and the sampling cylinder 22.

[0115] In this embodiment, in the initial state, the plug 5 is restricted in the corresponding sampling channel 12 by the limiting member 54. At this time, the sampling cylinder 22 is moved upward to contact the plug 5, so that the docking block 58 is inserted into the docking groove 59 and the two are docked through the magnetic attraction part. After docking, the limiting member 54 releases the restriction on the plug 5, so that the sampling cylinder 22 and the plug 5 can be synchronously driven into the mixing cylinder 11. When the sampling cylinder 22 needs to be reset to leave the mixing cylinder 11, the sampling cylinder 22 is moved and the plug 5 is driven downward synchronously. When the plug 5 moves into the corresponding sampling channel 12, the limiting member 54 is moved again to limit the plug 5, so that the plug 5 cannot leave the sampling channel 12. As the sampling cylinder 22 continues to move downward, the magnetic attraction part is disconnected, and the docking block 58 is pulled out from the docking groove 59. At this time, the sampling cylinder 22 and the plug 5 are disconnected.

[0116] like Figure 13 As shown, the contact part 51 is an arc shape that protrudes towards the inner cavity of the mixing cylinder 11.

[0117] In this embodiment, the plug 5 is driven to extend into the mixing cylinder 11 and contact the material. The contact part 51 that contacts the material first is designed as a raised arc shape, so the compression of the material can be reduced during the movement and contact with the material. When the material contacts the raised arc shape, it is diverted to all sides, which can improve the uniformity detection accuracy.

[0118] like Figure 14 As shown, the contact part 51 is an arc shape with the same curvature as the inner wall of the mixing cylinder 11.

[0119] In this embodiment, since the contact part 51 is a concave arc shape and has the same curvature as the inner wall of the mixing cylinder 11, when the plug 5 is located in the sampling channel 12 and the sampling channel 12 is blocked, the material will not fall into the dead corner between the contact part 51 and the sampling channel 12, and the stirring component in the mixing cylinder 11 can more comprehensively mix all the materials.

[0120] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
