Description

Technical Field

[0001] This utility model relates to the field of glass fiber production technology, and more specifically, to a sampling device. Background Technology

[0002] Currently, in the glass fiber manufacturing industry, the raw materials used to produce glass fiber include a variety of mineral powders and chemical raw material powders. In order to ensure the production quality of glass fiber, it is necessary to sample and test the raw materials of glass fiber.

[0003] In existing technology, workers usually climb to the top of the tanker truck, manually insert the sampling gun into the hopper where the raw materials are stored, and then insert the sampling gun into the raw material pile to take samples of the raw materials, which are then tested.

[0004] However, during the transportation of raw materials, the bumpy road makes the raw materials in the silo compacted. It is more difficult for workers to insert the sampling gun into the raw material pile, and the sampling gun can only be inserted to a depth of 30 centimeters. This increases the labor intensity of the workers and reduces the accuracy of sample testing, resulting in poor sampling effect of raw materials. Utility Model Content

[0008] Furthermore, the sampling structure has a first mating part, and the sleeve structure has a second mating part. One of the first mating part and the second mating part is a protrusion, and the other of the first mating part and the second mating part is a recess. The protrusion extends into the recess and slides along the extension direction of the recess. The recess has two ends. When the protrusion slides to the end, the end limits and stops the protrusion.

[0009] Furthermore, the sampling component also includes a blocking structure, which is disposed on the sleeve structure to increase the contact area between the sleeve structure and the sample to be sampled.

[0010] Furthermore, the sleeve structure includes: a sleeve portion, sleeved on the sampling structure, the sleeve portion having a feed inlet and a second mating portion; an insertion portion, disposed on the end of the sleeve portion away from the bearing structure, the diameter of the insertion portion gradually decreasing along the direction from the sleeve portion to the insertion portion to form a conical structure; and a spiral blade, disposed on the end of the sleeve portion away from the bearing structure.

[0011] Furthermore, the sampling device also includes an adjustment assembly, which includes: a first sliding structure, comprising a first slide rail and a first slider, the first slide rail being mounted on the frame and extending along a first preset direction, and the first slider being slidably engaged with the first slide rail; a second sliding structure, comprising a second slide rail and a second slider, the second slide rail being mounted on the first slider and extending along a second preset direction, and the second slider being slidably engaged with the second slide rail; and a third sliding structure, comprising a third slide rail and a third slider, the third slide rail being mounted on the second slider and extending along a third preset direction, and the third slider being slidably engaged with the third slide rail, the third slider being used to mount a load-bearing structure; wherein the first preset direction, the second preset direction, and the third preset direction are arranged perpendicularly to each other.

[0012] Furthermore, the adjustment assembly also includes: a first drive structure disposed on the second slide rail, the first drive structure being drivenly connected to the first slider to drive the first slider to move; a second drive structure disposed on the third slide rail, the second drive structure being drivenly connected to the second slider to drive the second slider to move; and a third drive structure disposed on the support structure, the third drive structure being drivenly connected to the third slider to drive the third slider to move.

[0013] Furthermore, the adjustment assembly also includes: a first transmission structure, including a first gear and a first rack, a first drive structure being driven connected to the first gear to drive the first gear to rotate, and the first rack being disposed on the first slide rail and meshing with the first gear; a second transmission structure, including a second gear and a second rack, a second drive structure being driven connected to the second gear to drive the second gear to rotate, and the second rack being disposed on the second slide rail and meshing with the second gear; and a third transmission structure, including a third gear and a third rack, a third drive structure being driven connected to the third gear to drive the third gear to rotate, and the third rack being disposed on the third slide rail and meshing with the third gear.

[0014] Furthermore, there are at least two first slide rails, which are arranged opposite to each other on the frame. There are at least two sets of first sliders, which are arranged in a one-to-one correspondence with the at least two first slide rails. The second slide rail is connected to the at least two sets of first sliders. Each set of first sliders includes at least two first sliders, which are spaced apart along the extension direction of the first slide rail.

[0015] Furthermore, the first drive structure includes a drive unit and a transmission shaft. The drive unit is sleeved on the transmission shaft and drives the transmission shaft to rotate. The two ends of the transmission shaft are respectively connected to the first gear.

[0016] By applying the technical solution of this utility model, the supporting structure of the sampling device is adjustablely positioned on the frame. The sampling component includes a sampling structure and a sleeve structure. The sampling structure is mounted on the supporting structure, and the sleeve structure is sleeved on the sampling structure. The sampling structure is rotatably mounted to drive the sleeve structure to rotate. The sleeve structure has a feed inlet, and the sampling structure has a feed trough. The sampling structure has a feeding position that connects the feed trough and the feed inlet, and a sealing position that blocks the feed inlet. Thus, when workers need to sample raw materials, the arrangement of the supporting structure allows them to adjust its position to a suitable sampling location, ensuring the accuracy of the sampling device's positioning. Simultaneously, the rotation of the sleeve structure by the sampling structure allows the sampling component to rotate and extend into the compacted raw material pile, increasing the depth of insertion into the raw material pile. This ensures that the sample reflects the overall condition of the raw material, guaranteeing the accuracy of sample detection and improving the sampling effect. This solves the problem of poor sampling effect for glass fiber raw materials in existing technologies. Meanwhile, the sampling structure is designed in two ways: firstly, by connecting the feed trough and the feed inlet, the raw materials can enter the feed trough through the feed inlet to achieve sampling of the raw materials; secondly, by sealing the feed inlet, the raw materials entering the feed trough are prevented from spilling out, thus ensuring the reliability of the feed trough's capacity and the sampling reliability of the sampling device.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] To address the problem of poor material handling efficiency for glass fiber in existing technologies, this application provides a sampling device.

[0035] like Figures 1 to 8 As shown, the sampling device includes a frame, a supporting structure 10, and a sampling assembly 20. The supporting structure 10 is adjustablely positioned on the frame. The sampling assembly 20 includes a sampling structure 21 and a sleeve structure 22. The sampling structure 21 is mounted on the supporting structure 10, and the sleeve structure 22 is sleeved on the sampling structure 21. The sampling structure 21 is rotatably mounted to drive the sleeve structure 22 to rotate. The sleeve structure 22 has a feed inlet 2211, and the sampling structure 21 has a feed trough 211. The sampling structure 21 has a feeding position that connects the feed trough 211 to the feed inlet 2211 and a blocking position that blocks the feed inlet 2211.

[0036] Using the technical solution of this embodiment, the supporting structure 10 of the sampling device is adjustablely positioned on the frame. The sampling assembly 20 includes a sampling structure 21 and a sleeve structure 22. The sampling structure 21 is disposed on the supporting structure 10, and the sleeve structure 22 is sleeved on the sampling structure 21. The sampling structure 21 is rotatably disposed to drive the sleeve structure 22 to rotate. The sleeve structure 22 has a feed inlet 2211, and the sampling structure 21 has a feed groove 211. The sampling structure 21 has a feeding position that connects the feed groove 211 to the feed inlet 2211 and a blocking position that blocks the feed inlet 2211. Thus, when workers need to sample raw materials, the arrangement of the supporting structure 10 allows them to adjust its position to ensure it is in a suitable sampling location, guaranteeing the positioning accuracy of the sampling device. Meanwhile, the arrangement of the sampling structure 21 driving the sleeve structure 22 to rotate allows the sampling component 20 to rotate and extend into the compacted raw material pile, increasing the depth of the sampling device into the raw material pile. This ensures that the raw material sampling reflects the overall condition of the raw material, guarantees the accuracy of sample detection, and thus improves the sampling effect. This solves the problem of poor raw material sampling by workers in the prior art. Furthermore, the arrangement of the sampling structure 21, on the one hand, connects the feed trough 211 to the feed inlet 2211, allowing the raw material to enter the feed trough 211 through the feed inlet 2211 for sampling; on the other hand, by sealing the feed inlet 2211, it ensures that the raw material entering the feed trough 211 is not spilled, achieving reliable capacity of the feed trough 211 and thus ensuring the sampling reliability of the sampling device.

[0037] In this embodiment, the sampling structure 21 is rod-shaped, and the end away from the bearing structure 10 has a feed trough 211.

[0038] Specifically, the sampling structure 21 is rotatably arranged along its own central axis. In the direction from the sampling structure 21 to the sleeve structure 22, the sampling structure 21 rotates clockwise along its own central axis, so that the sampling structure 21 is in the feeding position; the sampling structure 21 rotates counterclockwise along its own central axis, so that the sampling structure 21 is in the blocking position.

[0039] like Figure 1 As shown, the sampling device also includes a drive component 30, which is connected to the sampling structure 21 to drive the sampling structure 21 to rotate. In this way, the operator only needs to control the drive component 30 to rotate the sampling structure 21, reducing the operator's difficulty and workload. Simultaneously, the drive component 30 drives the sampling structure 21 to rotate and insert into the raw material pile, ensuring the power for the sampling device to insert into the raw material pile, ensuring the smoothness and reliability of sampling by the sampling structure 21, and thus ensuring the working efficiency and sampling effect of the sampling device.

[0040] In this embodiment, the driving component 30 is a servo motor. The servo motor achieves the switching of the sampling structure 21 between the feeding position and the blocking position by rotating forward and backward.

[0041] Specifically, the drive unit 30 is also connected to a reducer, which is sleeved on the sampling structure 21. The drive unit 30 drives the sampling structure 21 to rotate through the reducer.

[0042] like Figures 2 to 4 As shown, the sampling structure 21 has a first mating part 212, and the sleeve structure 22 has a second mating part 2212. One of the first mating part 212 and the second mating part 2212 is a protrusion, and the other of the first mating part 212 and the second mating part 2212 is a recess. The protrusion extends into the recess and slides along the extending direction of the recess. The recess has two ends, and when the protrusion slides to the end, the end limits and stops the protrusion. In this way, when the sampling structure 21 rotates, the protrusion extends into the recess and slides, allowing the sampling structure 21 to rotate within the sleeve structure 22, thereby enabling the sampling structure 21 to switch between the feeding position and the sealing position. At the same time, when the protrusion slides to the end of the concave part, the end can limit and stop the protrusion, so that the sampling structure 21 no longer rotates relative to the sleeve structure 22, but drives the sleeve structure 22 to rotate. Thus, the sampling structure 21 can drive the sleeve structure 22 to rotate whether it rotates to the feeding position or the blocking position, so that after the sampling component 20 rotates into the raw material pile to take material, it continues to rotate and leaves the raw material pile.

[0043] In this embodiment, the first mating part 212 is a protrusion, and the second mating part 2212 is a recess.

[0044] Specifically, the second mating part 2212 is in the shape of a through hole, protruding out of the through hole.

[0045] In this embodiment, the process of the protrusion sliding from one end to the other is also the process of the sampling structure 21 switching from the sampling position to the blocking position, or the sampling structure 21 switching from the blocking position to the sampling position.

[0046] like Figures 2 to 4As shown, the sampling assembly 20 also includes a blocking structure 23, which is disposed on the sleeve structure 22 to increase the contact area between the sleeve structure 22 and the sample to be sampled. In this way, the blocking structure 23 can form a blocking force with the raw material in the raw material pile. When the sampling structure 21 needs to switch from the feeding position to the blocking position, the blocking force between the blocking structure 23 and the raw material can block the sleeve structure 22, allowing the protrusion to slide from one end of the recess to the other. This allows the sampling structure 21 to first slide relative to the sleeve structure 22, and then the end-positioned stop on the protrusion drives the sleeve structure 22 and the blocking structure 23 to rotate, thus enabling the sampling device to leave the raw material pile. Simultaneously, the blocking structure 23 can also increase the probability of raw material entering the feed trough 211 during the rotation of the sampling structure 21 from the sampling position to the blocking position, further ensuring the sampling reliability of the sampling device.

[0047] In this embodiment, the blocking structure 23 is plate-shaped.

[0048] like Figures 2 to 4 As shown, the sleeve structure 22 includes a sleeve portion 221, an insertion portion 222, and a spiral blade 223. The sleeve portion 221 is sleeved on the sampling structure 21, and has a feed inlet 2211 and a second mating portion 2212. The insertion portion 222 is located at the end of the sleeve portion 221 away from the supporting structure 10, and the diameter of the insertion portion 222 gradually decreases along the direction from the sleeve portion 221 to the insertion portion 222 to form a conical structure. The spiral blade 223 is located at the end of the sleeve portion 221 away from the supporting structure 10. In this way, the sleeve structure 22 is sleeved on the sampling structure 21 through the sleeve portion 221. At the same time, the arrangement of the insertion portion 222 facilitates the insertion of the sleeve structure 22 into the compacted raw material pile, reduces the resistance of the sleeve structure 22 into the raw material pile, ensures the sampling depth of the sampling device, and improves the sampling effect of the sampling device. Meanwhile, the arrangement of the spiral blades 223 facilitates the up-and-down movement of the sleeve structure 22 within the compacted raw material pile, ensuring the smooth movement of the sleeve structure 22 and improving the sampling smoothness and efficiency of the sampling device.

[0049] like Figure 5 and Figure 7As shown, the sampling device further includes an adjustment assembly 40, which includes a first sliding structure 41, a second sliding structure 42, and a third sliding structure 43. The first sliding structure 41 includes a first slide rail portion 411 and a first slider portion 412. The first slide rail portion 411 is mounted on the frame and extends along a first preset direction. The first slider portion 412 is slidably engaged with the first slide rail portion 411. The second sliding structure 42 includes a second slide rail portion 421 and a second slider portion 422. The second slide rail portion 421 is mounted on the first slider portion 412 and extends along a second preset direction. The second slider portion 422 is slidably engaged with the second slide rail portion 421. The third sliding structure 43 includes a third slide rail portion 431 and a third slider portion 432. The third slide rail portion 431 is mounted on the second slider portion 422 and extends along a third preset direction. The third slider portion 432 is slidably engaged with the third slide rail portion 431. The third slider portion 432 is used to mount the support structure 10. The first, second, and third preset directions are arranged perpendicularly to each other. Thus, the adjusting component 40 allows the supporting structure 10 to move along the first preset direction via the first sliding structure 41, along the second preset direction via the second sliding structure 42, and along the third preset direction via the third sliding structure 43. This achieves adjustable positioning of the supporting structure 10, enabling the sampling device to adapt to material tank trucks of different sizes and locations, improving its versatility. Simultaneously, the aforementioned sliding arrangement ensures smooth movement of the supporting structure 10, improves the smoothness of the sampling device's movement, reduces the labor intensity of workers, further improves sampling efficiency and quality, and ultimately enhances the production quality of glass fiber.

[0050] like Figure 5 As shown, the first preset direction is the X direction, the second preset direction is the Y direction, and the third preset direction is the Z direction. The tank truck is located below the sampling device, and the Z direction is the direction in which the sampling structure 21 extends into the tank truck.

[0051] In this embodiment, at least a portion of the third slide rail 431 is made of aluminum alloy.

[0052] like Figure 1 , Figure 5 and Figure 8As shown, the adjustment assembly 40 also includes a first drive structure 44, a second drive structure 45, and a third drive structure 46. The first drive structure 44 is mounted on the second slide rail 421 and is driven by the first slider 412 to drive its movement. The second drive structure 45 is mounted on the third slide rail 431 and is driven by the second slider 422 to drive its movement. The third drive structure 46 is mounted on the support structure 10 and is driven by the third slider 432 to drive its movement. In this way, by activating the first drive structure 44, the second drive structure 45, and the third drive structure 46, the operator can move the support structure 10, reducing the difficulty and labor intensity of operation, automating the adjustment assembly 40, and ensuring the accuracy and reliability of the support structure 10's movement.

[0053] In this embodiment, the first drive structure 44, the second drive structure 45, and the third drive structure 46 are all servo motors.

[0054] In this embodiment, the first slider part 412 is designed as a trolley, and the trolley has four rollers, which are tumblingly connected to the first slide rail part 411.

[0055] like Figure 6 and Figure 8 As shown, the adjustment assembly 40 further includes a first transmission structure 47, a second transmission structure 48, and a third transmission structure 49. The first transmission structure 47 includes a first gear 471 and a first rack 472. A first drive structure 44 is drivenly connected to the first gear 471 to drive its rotation. The first rack 472 is disposed on the first slide rail portion 411 and meshes with the first gear 471. The second transmission structure 48 includes a second gear and a second rack 481. A second drive structure 45 is drivenly connected to the second gear to drive its rotation. The second rack 481 is disposed on the second slide rail portion 421 and meshes with the second gear. The third transmission structure 49 includes a third gear and a third rack 491. A third drive structure 46 is drivenly connected to the third gear to drive its rotation. The third rack 491 is disposed on the third slide rail portion 431 and meshes with the third gear. In this way, the first driving structure 44 drives the first slider 412 through the first transmission structure 47, the second driving structure 45 drives the second slider 422 through the second transmission structure 48, and the third driving structure 46 drives the third slider 432 through the third transmission structure 49, thus ensuring the accuracy and reliability of the transmission of driving force and further ensuring the motion reliability of the bearing structure 10.

[0056] In this embodiment, the second drive structure 45 is also connected to a reducer, which is connected to the second gear. The second drive structure 45 drives the second gear to rotate through the reducer.

[0057] In this embodiment, the third drive structure 46 is also connected to a reducer, which is connected to the third gear. The third drive structure 46 drives the third gear to rotate through the reducer.

[0058] like Figure 5 As shown, there are at least two first slide rail sections 411, which are arranged opposite to each other on the frame. There are at least two sets of first slider sections 412, with each set corresponding to one of the first slide rail sections 411. A second slide rail section 421 is connected to each of the at least two sets of first slider sections 412. Each set of first slider sections 412 includes at least two first slider sections 412, which are spaced apart along the extending direction of the first slide rail section 411. This arrangement of two first slide rail sections 411 and two sets of first slider sections 412 can distribute the force on the second slide rail section 421, ensuring the sliding reliability of the second slide rail section 421, improving its motion stability, and further ensuring the adjustment reliability of the load-bearing structure 10. Simultaneously, the arrangement of each set of first slider sections 412 including two first sliding parts improves the smoothness of the sliding of the second slide rail section 421.

[0059] In this embodiment, two first slide rail sections 411 are provided.

[0060] It should be noted that the number of first slide rail sections 411 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of first slide rail sections 411 can be three, four, six, eight, or more.

[0061] In this embodiment, each group of first slider parts 412 is provided in two.

[0062] It should be noted that the number of first slider sections 412 in each group is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of first slider sections 412 in each group can be three, four, six, eight, or more.

[0063] like Figure 5 , Figure 6 and Figure 8As shown, the first driving structure 44 includes a driving part 441 and a transmission shaft 442. The driving part 441 is sleeved on the transmission shaft 442 and drives the transmission shaft 442 to rotate. The two ends of the transmission shaft 442 are respectively connected to the first gear 471. In this way, the first driving structure 44 drives the transmission shaft 442 through the driving part 441 to drive the two first gears 471 to rotate, realizing the sliding of the second slide rail part 421 on the two first slide rail parts 411. This ensures the sliding reliability of the second slide rail part 421, while also reducing the structural complexity of the sampling device and improving the economy of the sampling device.

[0064] In this embodiment, the first drive structure 44 is also connected to a reducer, which is sleeved on the transmission shaft 442. The first drive structure 44 drives the transmission shaft 442 to rotate through the reducer.

[0065] In this embodiment, the second slide rail 421 is provided with two seated bearings. The two seated bearings are located on both sides of the first drive structure 44 and are arranged in a mirror symmetrical manner. The two seated bearings are sleeved on the drive shaft 442 to provide double support for the drive shaft 442, thereby ensuring the rotational stability and transmission reliability of the drive shaft 442.

[0066] Specifically, when the staff needs to sample the raw materials, the staff first activates the first drive structure 44 to drive the second slide rail 421 to slide, then activates the second drive structure 45 to drive the third slide rail to slide, so that the bearing structure 10 moves to the material tanker to be sampled. Then, the drive component 30 is activated to drive the sampling structure 21 to rotate clockwise along its own central axis. Then, the third drive structure 46 is activated to drive the bearing structure 10 to move closer to the material tanker until the sampling structure 21 and the sleeve structure 22 enter the raw material pile. Afterwards, the staff controls the sampling structure 21 to rotate in the opposite direction. At this time, the blocking structure 23 and the raw material can cooperate to form a resistance, causing the protrusion to slide from one end to the other end, thereby enabling the sampling structure 21 to rotate relative to the sleeve structure 22. This allows the sampling structure 21 to rotate from the sampling position to the blocking position. During this process, the raw material enters the feed trough 211 and is blocked until the protrusion is stopped by the end limit. The sleeve structure 22 follows the rotation of the sampling structure 21, leaves the raw material pile and moves to the staff, thus completing the raw material sampling operation.

[0067] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0068] The sampling device's supporting structure is adjustablely positioned on the frame. The sampling assembly includes a sampling structure and a sleeve structure. The sampling structure is mounted on the supporting structure, and the sleeve structure is fitted onto the sampling structure. The sampling structure is rotatable, allowing the sleeve structure to rotate. The sleeve structure has a feed inlet, and the sampling structure has a feed trough. The sampling structure has a feeding position connecting the feed trough and the feed inlet, and a sealing position to block the feed inlet. This configuration allows operators to adjust the position of the supporting structure when sampling raw materials, ensuring accurate positioning of the sampling device. Simultaneously, the rotation of the sleeve structure by the sampling structure allows the sampling assembly to extend into the compacted raw material pile, increasing the depth of penetration and ensuring that the sample reflects the overall condition of the raw material, thus guaranteeing accurate sample testing and improving sampling effectiveness. This solves the problem of poor sampling results for glass fiber raw materials in existing technologies. Meanwhile, the sampling structure is designed in two ways: firstly, by connecting the feed trough and the feed inlet, the raw materials can enter the feed trough through the feed inlet to achieve sampling of the raw materials; secondly, by sealing the feed inlet, the raw materials entering the feed trough are prevented from spilling out, thus ensuring the reliability of the feed trough's capacity and the sampling reliability of the sampling device.
