Abstract
Description
Technical Field
[0001] This application relates to the field of carbon fiber manufacturing technology, and more specifically, to a portable manual sampling device. Background Technology
[0002] Carbonization is a crucial step in carbon fiber production. To ensure carbon fiber quality, sampling and analysis are typically performed during carbonization to allow for timely adjustments to process parameters based on test results. Currently, the primary sampling method involves manually winding the sample onto a winding shaft. This method makes it difficult to distribute the carbon fiber evenly on the shaft, resulting in a higher sample density in the central area and lower density at the edges. This leads to greater compressive stress on the carbon fiber in the central area, causing severe sample deformation. The longer the sample, the more severe the deformation. On one hand, deformed samples hinder subsequent unwinding, affecting the efficiency of performance testing; on the other hand, sample deformation also impacts the accuracy of performance testing. Utility Model Content
[0003] The purpose of this application is to provide a portable manual sampling device that can effectively solve the problem of severe deformation of carbon fibers during the sampling process.
[0004] The embodiments of this application are implemented as follows:
[0005] In a first aspect, embodiments of this application provide a portable manual sampling device, including a base, a winding unit, a guide wire unit, and a drive unit. The winding unit includes a first support and a winding shaft. The first support is connected to the base, and the winding shaft is rotatably connected to the first support for winding carbon fiber samples. The guide wire unit includes a reciprocating linear motion assembly and a guide wire component. The reciprocating linear motion assembly is connected to the base, and the guide wire component is fixed to the reciprocating linear motion assembly. Along the conveying direction of the carbon fiber samples, the guide wire component is located upstream of the winding unit for adjusting the conveying direction of the carbon fiber samples. The drive unit is connected to the winding shaft and the reciprocating linear motion assembly respectively. The drive unit is configured such that, under manual drive, the winding shaft can rotate, and the reciprocating linear motion assembly can synchronously drive the guide wire component to perform reciprocating linear motion along the axial direction of the winding shaft.
[0006] In the above technical solution, the portable manual sampling device is configured as a base, a winding unit, a guide wire unit, and a drive unit working together. Specifically, the winding unit includes a first bracket connected to the base and a winding shaft rotatably connected thereto, which can wind up the carbon fiber sample by rotation. The guide wire unit includes a reciprocating linear motion component connected to the base and a guide wire fixedly connected thereto, the guide wire being located upstream of the winding unit and used to adjust the conveying direction of the carbon fiber sample. The drive unit is connected to both the winding shaft and the reciprocating linear motion component, and is configured such that, under manual drive, the winding shaft can rotate and the reciprocating linear motion component can synchronously drive the guide wire to reciprocate linearly along the axial direction of the winding shaft. Through the synergistic effect of the above multiple functional components, the entire portable manual sampling device can be directly driven by human power, facilitating the collection of carbon fiber samples of the required length. Furthermore, since the guide wire can reciprocate linearly along the axial direction of the winding shaft during rotation, the wound carbon fiber sample can be evenly distributed on the winding shaft, effectively solving the problem of severe deformation of carbon fiber during sampling.
[0007] In some alternative implementations, the reciprocating linear motion assembly includes a second support, a rotating rod, and a sliding sleeve. The second support is connected to the base, the rotating rod is spaced apart from the winding shaft, the rotating rod is rotatably connected to the second support and is driven by the drive unit, and the surface of the rotating rod has two threaded grooves with the same pitch and opposite directions. The sliding sleeve is threadedly connected to the threaded grooves on the rotating rod and is circumferentially limited. The wire guide is connected to the sliding sleeve so that the wire guide can reciprocate along the axial direction of the winding shaft during the rotation of the rotating rod.
[0008] In the above technical solution, the reciprocating linear motion component is configured as a second support, a rotating rod, and a sliding sleeve that cooperate with each other. The rotating rod has two threaded grooves with the same pitch and opposite directions on its surface. The sliding sleeve is threadedly connected to the threaded grooves on the rotating rod, and the sliding sleeve is circumferentially limited. That is, the combination of the rotating rod and the sliding sleeve is similar to that of a reciprocating lead screw. This type of reciprocating linear motion component has the advantage of good movement stability.
[0009] In some alternative implementations, the reciprocating linear motion assembly further includes a limiting guide rail connected to the second bracket and having a limiting groove. The extending direction of the limiting groove is parallel to the axial direction of the winding shaft. The first end of the sliding sleeve is threadedly connected to the threaded groove on the rotating rod. The wire guide is connected to the first end of the sliding sleeve, and the opposite second end is embedded in the limiting groove, so that the wire guide can reciprocate along the axial direction of the winding shaft during the rotation of the rotating rod.
[0010] In the above technical solution, the reciprocating linear motion component is equipped with a limiting guide rail. Specifically, the limiting guide rail is connected to the second bracket and has a limiting groove extending axially along the winding shaft. The first end of the sliding sleeve is threadedly connected to the threaded groove on the rotating rod, and the opposite second end is embedded in the limiting groove. By setting the limiting guide rail, the circumferential limiting of the sliding sleeve is achieved, which has the advantages of good limiting effect and simple structure.
[0011] In some alternative implementations, the guide wire includes two vertically spaced stops, the bottoms of which are connected to the tops of the sliding sleeve, and a gap between the two stops for the carbon fiber sample to pass through.
[0012] In the above technical solution, the guide wire component is set up as two vertically arranged baffles that cooperate with each other. During the carbon fiber sample transportation process, the top of the carbon fiber sample will not be limited, which has the advantage of adjustable sample feeding height, thus making it easy to match with production lines of different heights.
[0013] In some alternative embodiments, the drive unit includes a first gear, a second gear, and a drive unit. The first gear and the second gear mesh with each other, and the drive unit is connected to the first gear and configured to drive the first gear to rotate under manual drive. The first gear is coaxially arranged and fixedly connected to the winding shaft for driving the winding shaft to rotate, and the second gear is coaxially arranged and fixedly connected to the rotating rod for driving the rotating rod to rotate.
[0014] In the above technical solution, the drive unit is configured to have a first gear, a second gear, and a drive unit that cooperate with each other. Specifically, the first gear and the second gear mesh with each other, and the drive unit is connected to the first gear and configured to drive the first gear to rotate under manual drive. The first gear is coaxially arranged and fixedly connected to the winding shaft, and the second gear is coaxially arranged and fixedly connected to the rotating rod. The gear transmission method gives the drive unit the advantage of a relatively compact overall structure, which makes it easy to transfer the portable manual sampling device to the sampling position for sampling according to actual needs.
[0015] In some alternative implementations, the gear ratio of the first gear and the second gear is 1:1.
[0016] In the above technical solution, the first gear and the second gear are set to have the same number of teeth so that the rotation speed of the winding shaft and the rotating rod is the same, thereby making the rotation of the winding shaft and the reciprocating linear motion of the guide wire highly synchronized, which can further improve the uniformity of the distribution of carbon fiber samples on the winding shaft (the more uniform the distribution of carbon fiber samples, the less likely they are to deform due to compression).
[0017] In some alternative implementations, the drive unit is a crank handle, one end of which is connected to the side of the first gear away from the winding shaft.
[0018] In the above technical solution, the drive unit is set in the form of a crank handle, which has the advantages of being easy to drive by hand and having a relatively simple structure.
[0019] In some alternative implementations, the bottom of the base has a palm-shaped groove for gripping.
[0020] In the above technical solution, a palm-shaped groove for gripping is added to the bottom of the base, which can improve the handheld stability of the portable manual sampling device during the transfer process, so as to transfer the portable manual sampling device to the sampling position more safely.
[0021] In some alternative implementations, the inner wall of the palm groove is provided with an anti-slip layer.
[0022] In the above technical solution, an anti-slip layer is added to the inner wall of the palm groove, which can further improve the handheld stability of the portable manual sampling device during the transfer process by increasing the surface roughness.
[0023] In some alternative implementations, the base is an arc-shaped base with a mounting groove, and the corresponding central angle of the base is 120 to 150°. The upper end of the mounting groove is open and used to mount the winding unit, the wire guide unit and the drive unit.
[0024] In the above technical solution, the base is set to be arc-shaped, which makes it easier for the hand to hold and thus facilitates the transfer of the portable manual sampling device; at the same time, the central angle corresponding to the arc-shaped base is limited to the above range, which also makes it less likely to obstruct the incoming carbon fiber sample, thus facilitating the transport of the carbon fiber sample.

[0037] The following is a detailed description of a portable manual sampling device provided in this application.
[0038] See Figure 1 In a first aspect, embodiments of this application provide a portable manual sampling device 10, including a base 100, a winding unit 200, a guide wire unit 300, and a drive unit 400. The winding unit 200 includes a first support 210 and a winding shaft 220. The first support 210 is connected to the base 100, and the winding shaft 220 is rotatably connected to the first support 210 for winding a carbon fiber sample 20. The guide wire unit 300 includes a reciprocating linear motion assembly 310 and a guide wire 320. The reciprocating linear motion assembly 310 is connected to the base 100, and the guide wire 320 is fixed to the reciprocating linear motion assembly 310. Along the conveying direction of the carbon fiber sample 20, the guide wire 320 is located within the winding unit. Upstream of 200, it is used to adjust the conveying direction of the carbon fiber sample 20 (so that the carbon fiber sample 20 can reach a suitable position on the winding shaft 220 and be wound up after passing through the guide wire 320); the drive unit 400 is connected to the winding shaft 220 and the reciprocating linear motion component 310 respectively. The drive unit 400 is configured such that the winding shaft 220 can rotate under manual drive, and the reciprocating linear motion component 310 can synchronously drive the guide wire 320 to perform reciprocating linear motion along the axial direction of the winding shaft 220.
[0039] In this application, the portable manual sampling device 10 is configured as a base 100, a winding unit 200, a guide wire unit 300, and a drive unit 400 working together. Specifically, the winding unit 200 includes a first bracket 210 connected to the base 100 and a winding shaft 220 rotatably connected thereto. The winding shaft 220 can wind up the carbon fiber sample 20 by rotation. The guide wire unit 300 includes a reciprocating linear motion component 310 connected to the base 100 and a guide wire member 320 fixedly connected thereto. The guide wire member 320 is located upstream of the winding unit 200 and is used to adjust the conveying direction of the carbon fiber sample 20. The drive unit 400 is connected to the winding shaft 220 and the reciprocating linear motion component 310 respectively. The drive unit 400 is configured such that, under manual drive, the winding shaft 220 can rotate and the reciprocating linear motion component 310 can synchronously drive the guide wire member 320 to perform reciprocating linear motion along the axial direction of the winding shaft 220. Through the synergistic effect of the above-mentioned multiple functional components, the entire portable manual sampling device 10 can be directly driven by human power, making it convenient to obtain carbon fiber samples 20 of the required length; and since the guide wire 320 can reciprocate linearly along the axial direction of the winding shaft 220 during the rotation of the winding shaft 220, it can also make the wound carbon fiber sample 20 evenly distributed on the winding shaft 220, thereby effectively solving the problem of severe deformation of carbon fiber during the sampling process.
[0040] It should be noted that the form in which the winding shaft 220 and the first bracket 210 are rotatably connected is not limited. For example, both ends of the winding shaft 220 and the first bracket 210 can be rotatably connected, or only one end of the winding shaft 220 can be rotatably connected to the first bracket 210.
[0041] See Figure 1 As an example, both ends of the winding shaft 220 are rotatably connected to the first bracket 210.
[0042] In this embodiment, both ends of the winding shaft 220 are rotatably connected to the first bracket 210, which has the advantages of high structural stability and good load-bearing capacity.
[0043] It should be noted that the specifications of the winding shaft 220 are not limited and can be set according to actual needs.
[0044] As an example, the outer diameter of the winding shaft 220 is 45 to 55 mm, for example, but not limited to any one of 45 mm, 46 mm, 47 mm, 48 mm, 49 mm, 50 mm, 51 mm, 52 mm, 53 mm, 54 mm and 55 mm or any range between two of them.
[0045] In this embodiment, limiting the outer diameter of the winding shaft 220 to the above-mentioned range can meet the sampling requirements of carbon fiber, while also having a small size and weight, thereby facilitating the transfer of the portable manual sampling device 10.
[0046] See Figure 2 As an example, the reciprocating linear motion assembly 310 includes a second support 311, a rotating rod 312, and a sliding sleeve 313. The second support 311 is connected to the base 100. The rotating rod 312 is distributed side by side with the winding shaft 220 at intervals. The rotating rod 312 is rotatably connected to the second support 311 and is connected to the drive unit 400 for transmission. The surface of the rotating rod 312 is provided with two threaded grooves 3121 with the same pitch and opposite directions. The sliding sleeve 313 is threadedly connected to the threaded grooves 3121 on the rotating rod 312 and is circumferentially limited. The wire guide 320 is connected to the sliding sleeve 313 so that the wire guide 320 can reciprocate along the axial direction of the winding shaft 220 during the rotation of the rotating rod 312.
[0047] In this embodiment, the reciprocating linear motion assembly 310 is configured as a combination of a second support 311, a rotating rod 312, and a sliding sleeve 313. The rotating rod 312 has two threaded grooves 3121 with the same pitch and opposite directions on its surface. The sliding sleeve 313 is threadedly connected to the threaded grooves 3121 on the rotating rod 312, and the sliding sleeve 313 is circumferentially limited. That is, the combination of the rotating rod 312 and the sliding sleeve 313 is similar to that of a reciprocating lead screw. This type of reciprocating linear motion assembly 310 has the advantage of good movement stability.
[0048] See Figure 2 As an example, the reciprocating linear motion assembly 310 also includes a limiting guide rail 314, which is connected to the second bracket 311 and has a limiting groove 3141. The extending direction of the limiting groove 3141 is parallel to the axial direction of the winding shaft 220. The first end of the sliding sleeve 313 is threadedly connected to the threaded groove 3121 on the rotating rod 312. The wire guide 320 is connected to the first end of the sliding sleeve 313, and the opposite second end is embedded in the limiting groove 3141, so that the wire guide 320 can reciprocate along the axial direction of the winding shaft 220 during the rotation of the rotating rod 312.
[0049] In this embodiment, the reciprocating linear motion component 310 is equipped with a limiting guide rail 314. Specifically, the limiting guide rail 314 is connected to the second bracket 311 and has a limiting groove 3141 extending axially along the winding shaft 220. The first end of the sliding sleeve 313 is threadedly connected to the threaded groove 3121 on the rotating rod 312, and the opposite second end is embedded in the limiting groove 3141. The circumferential limiting of the sliding sleeve 313 is achieved by setting the limiting guide rail 314, which has the advantages of good limiting effect and simple structure.
[0050] See Figure 2 As an example, the guide wire 320 includes two vertically spaced baffles 321, the bottoms of which are connected to the tops of the sliding sleeve 313 respectively, and there is a gap between the two baffles 321 for the carbon fiber sample 20 to pass through.
[0051] In this embodiment, the guide wire 320 is configured as two vertically arranged baffles 321 that cooperate with each other. During the conveying of the carbon fiber sample 20, the top of the carbon fiber sample 20 will not be limited, which has the advantage of adjustable sample height, thus making it easy to match with production lines of different heights.
[0052] In other possible implementations, the guide wire 320 may also be configured as a ceramic eye, i.e., a ring through which the carbon fiber sample 20 can pass.
[0053] It should be noted that the transmission form of the drive unit 400 is not limited and can be adapted to actual needs. For example, it can be a gear transmission or a belt transmission.
[0054] See Figure 1 and Figure 3 As an example, the drive unit 400 includes a first gear 410, a second gear 420, and a drive unit 430. The first gear 410 and the second gear 420 mesh with each other. The drive unit 430 is connected to the first gear 410 and is configured to drive the first gear 410 to rotate under manual drive. The first gear 410 is coaxially arranged and fixedly connected to the winding shaft 220 for driving the winding shaft 220 to rotate. The second gear 420 is coaxially arranged and fixedly connected to the rotating rod 312 for driving the rotating rod 312 to rotate.
[0055] In this embodiment, the drive unit 400 is configured to have a first gear 410, a second gear 420, and a drive unit 430 working together. Specifically, the first gear 410 and the second gear 420 mesh with each other, and the drive unit 430 is connected to the first gear 410 and configured to drive the first gear 410 to rotate under manual drive. The first gear 410 is coaxially arranged and fixedly connected to the winding shaft 220, and the second gear 420 is coaxially arranged and fixedly connected to the rotating rod 312. The gear transmission method gives the drive unit 400 the advantage of a more compact overall structure, which makes it easier to transfer the portable manual sampling device 10 to the sampling position for sampling according to actual needs.
[0056] As an example, the gear ratio of the first gear 410 and the second gear 420 is 1:1.
[0057] In this embodiment, the first gear 410 and the second gear 420 are configured to have the same number of teeth so that the winding shaft 220 and the rotating rod 312 rotate at the same speed. This makes the rotation of the winding shaft 220 and the reciprocating linear motion of the guide wire 320 highly synchronized, thereby further improving the uniformity of the distribution of the carbon fiber sample 20 on the winding shaft 220 (the more uniform the distribution of the carbon fiber sample 20, the less likely it is to deform due to compression).
[0058] It should be noted that the form of the drive unit 430 is not limited and can be adapted to meet actual needs, as long as it can be driven by humans.
[0059] See Figure 1 and Figure 3 As an example, the drive unit 430 is a crank handle, one end of which is connected to the side of the first gear 410 away from the winding shaft 220.
[0060] In this embodiment, the drive unit 430 is set in the form of a crank handle, which has the advantages of being easy to drive by hand and having a relatively simple structure.
[0061] As an example, the bottom of the base 100 has a palm-shaped groove for gripping (not shown in the figure).
[0062] In this embodiment, a palm-shaped groove for gripping is added to the bottom of the base 100, which can improve the handheld stability of the portable manual sampling device 10 during the transfer process, so as to transfer the portable manual sampling device to the sampling position more safely.
[0063] As an example, the inner wall of the palm groove is provided with an anti-slip layer (not shown in the figure).
[0064] In this embodiment, an anti-slip layer is added to the inner wall of the palm-shaped groove, which can further improve the handheld stability of the portable manual sampling device 10 during the transfer process by increasing the surface roughness.
[0065] See Figure 4 As an example, the base 100 is an arc-shaped base 100 with a mounting groove, and the central angle of the base 100 is 120 to 150° (for example, but not limited to any one or any two of 120°, 125°, 130°, 135°, 140°, 145° and 150°). The upper end of the mounting groove is open and is used to mount the winding unit 200, the wire guide unit 300 and the drive unit 400.
[0066] In this embodiment, the base 100 is set to be arc-shaped, which makes it easier for the hand to hold and thus facilitates the transfer of the portable manual sampling device 10; at the same time, the central angle corresponding to the arc-shaped base 100 is limited to the above-mentioned range, which also makes it less likely to obstruct the incoming carbon fiber sample 20, thus facilitating the transport of the carbon fiber sample 20.
[0067] In other possible implementations, the base 100 may also be rectangular.
[0068] As an example, the base 100 is made of aluminum alloy.
[0069] In this embodiment, the base 100 made of aluminum alloy has the advantage of being lightweight, which makes it easier to move the portable manual sampling device 10.
[0070] It should be noted that, for any structural or functional components in the portable manual sampling device 10 that are not specifically described or limited, they may be configured in accordance with conventional choices in the art.
[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
