Description

Technical Field

[0001] This utility model belongs to the field of spinning process processing, specifically, it relates to a height-adjustable clamping device and a spinning thread washing tank. Background Technology

[0002] In the existing technology, when carbon fiber precursor is in the water washing process, the carbon fiber precursor is separated by a fiber separating device set in the water washing tank. (The structure of the fiber separating device is usually rod-shaped, and multiple fiber grooves or multiple fiber holes are set on the rod to separate multiple carbon fiber precursors to complete the fiber separating work) in order to reduce the problem of fiber tangling during the water washing process. In actual production use, it is necessary to adjust the height of the fiber separating device to achieve the height adjustment of the carbon fiber precursor to meet the preparation requirements required by the production site.

[0003] Currently, in this field, relatively simple workpiece fixing and splitting devices are commonly used, but they cannot adjust the height of the carbon fiber filaments. Another approach mainly uses a lifting mechanism composed of a simple bracket and bolts and nuts. For example, technicians adjust the position of the limit screw, only placing the screw against the splitting device. The force of the screw then holds the splitting device against the simple bracket, thus fixing it in place. While this allows for lifting and adjusting the splitting device, the structure itself has low reliability and is inconvenient for technicians to operate and adjust during production.

[0004] Furthermore, when the carbon fiber precursor is in the washing process, the carbon fiber precursor and the splitting device are constantly immersed in hot water. When those skilled in the art use a simple lifting mechanism to make adjustments, there is a risk of direct contact with the hot water, which may cause burns or other accidents, posing a certain safety hazard. Utility Model Content

[0005] In one respect, to solve at least some of the above-mentioned problems, this utility model provides a height-adjustable clamping device suitable for adjusting the position of spinning during processing, comprising: a base plate, a fixing part mounted on the base plate, a clamp, the clamp being movably connected or fixedly connected to the fixing part, the clamp having a clamping position, an adjusting rod, the adjusting rod being a lead screw, the clamp having an adjusting screw hole matching the adjusting rod, the adjusting rod passing through the clamp and mounted on the base plate, and the clamp being adjustable on the adjusting rod, the rod head of the adjusting rod facing the same direction as the end of the fixing part not in contact with the base plate, and the rod length of the adjusting rod being 2 to 6 times the minimum clamping height of the clamp.

[0006] Furthermore, when the clamp is movably connected to the fixing part, a guide through hole is provided on the clamp. The guide through hole matches the structure of the fixing part, and the fixing part passes through the clamp through the guide through hole.

[0007] Furthermore, the fixing part is a column structure, and the length direction of the fixing part is parallel to the axis of the adjusting rod.

[0008] Furthermore, the fixing part is detachably connected to the substrate, or the fixing part is integrally formed with the substrate.

[0009] Furthermore, the fixing part has a cylindrical structure, and there are two fixing parts. The two fixing parts are located on both sides of the adjusting rod, and the clamping position of the clamp is set between the adjusting rod and the guide through hole of the clamp.

[0010] Furthermore, when the clamp is fixedly connected to the fixing part, the fixing part is a scissor fork lifting structure, and the lifting direction of the fixing part is consistent with the axis of the adjusting rod. One end of the fixing part is mounted on the base plate, and the other end of the fixing part is set on the clamp.

[0011] Furthermore, the fixture includes an upper clamping member and a lower clamping member that cooperate to clamp each other. The upper clamping member has a first threaded hole, and the lower clamping member has a second threaded hole. The upper clamping member and the lower clamping member are screwed together and fixed.

[0012] Furthermore, the adjusting rod is positioned at the center of the clamp, and the clamping position of the clamp is located adjacent to the adjusting rod.

[0013] Furthermore, a buried hole is formed on the substrate, which matches the tail structure of the adjustment rod.

[0014] On the other hand, this utility model also discloses a spinning yarn washing tank, including: a washing tank body; a spinning yarn having a preset traveling direction within the spinning separation space; a height-adjustable clamping device as described in any of the preceding embodiments, the height-adjustable clamping device being set at a preset position within the washing tank body; and a yarn separating device, the yarn separating device having a rod-shaped structure, the middle part of the yarn separating device having multiple yarn separating grooves or yarn separating holes, both ends of the yarn separating device being matched with the clamping position of the clamp; the yarn separating device being height-adjustable and set inside the washing tank body through the height-adjustable clamping device.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0016] By adding this height-adjustable clamping device to the spinning process, operators can use tools to turn the adjusting rod to adjust the height of the clamp, thus meeting the different requirements for the preparation of carbon fiber precursor. The clamp is mounted on the substrate via a fixing part, preventing lateral movement or offset of the clamp.

[0025] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figures 1-4 As shown, this utility model provides a height-adjustable clamping device 100, suitable for adjusting the position of spinning during processing. It includes: a base plate 1, a fixing part 3 installed on the base plate 1, a clamp 2 movably connected or fixedly connected to the fixing part 3, the clamp 2 being installed on the base plate 1 through the fixing part 3, and the clamp 2 having a clamping position 27, an adjusting rod 4 being a lead screw, the clamp 2 having an adjusting screw hole 23 matching the adjusting rod 4, the adjusting rod 4 passing through the clamp 2 and being installed on the base plate 1, and the clamp 2 being adjustable on the adjusting rod 4, the rod head of the adjusting rod 4 facing the same direction as the end of the fixing part 3 that is not in contact with the base plate 1, and the rod length of the adjusting rod 4 being 2 to 6 times the minimum clamping height of the clamp 2.

[0030] In the above scheme, the lifting and adjusting clamping device is added to the spinning process. Those skilled in the art can use tools to turn the adjusting rod 4 to achieve the adjustment function of the clamp 2 on the adjusting rod 4, thereby meeting the preparation requirements of different carbon fiber precursors 600. The clamp 2 is mounted on the substrate 1 via the fixing part 3 to prevent lateral movement or offset of the clamp 2. The rod head of the adjusting rod 4 faces the same direction as the end of the fixing part 3 that is not in contact with the substrate 1; that is, the top of the adjusting rod 4 and the top of the fixing part 3 are both upwards, so that those skilled in the art can insert tools into the spinning line washing tank to turn the adjusting rod 4. The length of the adjusting rod 4 is set to 2-6 times the minimum clamping height of the clamp. While ensuring that the effective adjustment stroke of the adjusting rod 4 is sufficient for the needs of the production site, the length of the adjusting rod 4 is as long as possible so that the rod head of the adjusting rod 4 is closer to, or even higher than, the water surface in the spinning line washing tank, maximizing the distance between those skilled in the art and hot water or steam, increasing safety, without becoming an excessively long adjusting rod 4 that would be difficult for operators to turn.

[0031] For ease of description and understanding, the term "lateral" in this document refers to the axis perpendicular to the adjusting rod 4, and correspondingly, the term "longitudinal" refers to the axis parallel to the adjusting rod 4. The bottom end face of the substrate 1 is fixed in the spinning thread washing tank. The minimum clamping height of the clamp 2 is the minimum height of the clamp in the working state after clamping carbon fiber precursors 600 of different specifications. Preferably, the clamp 2 is adjusted by moving along the axis of the adjusting rod 4.

[0032] More specifically, the height-adjustable clamping device 100 is installed in the spinning line washing tank for processing carbon fiber precursor 600. During the production process, the carbon fiber precursor 600 and the height-adjustable clamping device 100 are immersed in hot water together. Those skilled in the art can use longer tools or install extended sleeves on the tools to ensure that only the workpiece contact end of the tool is immersed in the hot water, while the manual operating end of the tool is away from the hot water. This ensures lateral fixation of the clamping device 2 during lifting and lowering, and also reduces the risk of burns to technicians when adjusting the height of the clamping device 2.

[0033] Furthermore, the fixing part 3 is a column structure, and the axis of the fixing part 3 is parallel to the axis of the adjusting rod 4.

[0034] like Figure 1 , Figure 4 As shown, the clamp 2 is further provided with a guide through hole 24, which matches the structure of the fixing part 3. The fixing part 3 passes through the clamp 2 in the clamping direction of the clamp 2 through the guide through hole 24.

[0035] In the above scheme, the fixing part 3 is movably connected to the clamp 2, that is, the guide through hole 24 on the clamp 2 is clearance-fitted or transition-fitted with the fixing part 3 to ensure that the clamp 2 can slide relative to the fixing part 3 of the column structure, and still has the function of horizontally fixing the clamp 2.

[0036] Furthermore, there are two fixing parts 3, which are located on both sides of the adjusting rod 4.

[0037] like Figure 2 , Figure 3 As shown, the fixing part 3 is further configured as a column, and is detachably connected to the substrate 1. Preferably, the fixing part 3 is threadedly connected to the substrate 1, and a first mounting hole 12 is provided on the bottom end face of the substrate 1. Correspondingly, a second mounting hole 31 of the same specification is provided on the end of the fixing part 3 that contacts the substrate 1. Preferably, a limiting groove 13 matching the bottom structure of the fixing part 3 is provided on the top end face of the substrate 1. When installing, those skilled in the art first abut the fixing part 3 against the limiting groove 13 on the substrate 1, and then use bolts to screw the fixing part 3 to the substrate 1 from the bottom end face of the substrate 1.

[0038] It should be noted that, under normal circumstances, for ease of use, substrate 1 is usually directly soldered into the washing tank of the spinning line.

[0039] Furthermore, the fixing part 3 and the substrate 1 are manufactured in one piece. This manufacturing method can reasonably reduce the production process and assembly steps, and is more suitable for mass production and uniform specifications.

[0040] Furthermore, the fixing part 3 has a cylindrical structure.

[0041] It should also be noted that the top end face of the fixing part 3 and the top end face of the adjusting rod 4 are at the same height or at least approximately the same height, in order to ensure that the overall size of the adjustable clamping device 100 is appropriate.

[0042] Furthermore, the fixing part 3 is a scissor fork lifting structure, and the lifting direction of the fixing part 3 is consistent with the axis of the adjusting rod 4. One end of the fixing part 3 is mounted on the base plate 1, and the other end of the fixing part 3 is set on the clamp 2.

[0043] In the above embodiment, the top of the fixing part 3 of the scissor fork lifting structure is mounted on the bottom end face of the clamp 2, and the bottom of the fixing part 3 is mounted on the top end face of the base plate 1. Specifically, the scissor fork lifting structure includes a fixed scissor fork and a sliding scissor fork that cooperate with each other to achieve lifting.

[0044] Preferably, the upper part of the fixed scissor fork is screwed to the bottom end face of the clamp 2 via a bracket, and the lower part of the fixed scissor fork is screwed to the top end face of the base plate 2 via a bracket. The upper and lower parts of the fixed scissor fork have rotation points. The upper part of the sliding scissor fork is slidably connected to the clamp 2 via a matching upper slide rail, and the bottom of the sliding scissor fork is slidably connected to the base 2 via a matching lower slide rail. In addition, during the lifting process, it should be noted that the setting position of the adjusting rod 4 should never interfere with the changing scissor fork lifting structure.

[0045] The scissor lift structure is a technology known to those skilled in the art, and the specific installation method has been clearly described above. Therefore, the embodiment of the scissor lift structure with fixing part 3 is not shown in the accompanying drawings.

[0046] Furthermore, the head of the adjusting rod 4 faces the same direction as the end of the fixing part 3 that is not connected to the base plate 1, that is, the head of the adjusting rod 4 faces the top, which makes it convenient for those skilled in the art to use tools to turn the adjusting rod 4.

[0047] Furthermore, the adjustable clamping device 100 disclosed in this utility model has a base plate 1 that can be placed on the bottom side wall of the spinning washing tank of the carbon fiber precursor 600. The adjustable clamping device 100, mounted on the bottom wall of the spinning washing tank, allows for longitudinal adjustment of the carbon fiber precursor 600.

[0048] like Figure 1 , Figure 4 As shown, the clamp 2 further includes an upper clamping member 21 and a lower clamping member 22 that cooperate to clamp. The upper clamping member 21 has a first threaded hole 25, and the lower clamping member 22 has a second threaded hole 26. The upper clamping member 21 and the lower clamping member 22 are screwed together and fixed.

[0049] In the above scheme, there are at least two clamping positions 27 on the fixture 2, and the overall structure of the clamping position 27 formed by the cooperation of the upper clamping member 21 and the lower clamping member 22 is a cylindrical structure.

[0050] In one specific embodiment, the substrate 1 is welded and fixed inside the spinning thread washing tank. The fixing part 3 of the column structure is installed on the substrate 1 using bolts before welding and fixing. After the splitting device 300 is placed in the clamping position 27 of the clamp 2, the matching first threaded hole 25 and second threaded hole 26 on the upper clamping member 21 and the lower clamping member 22 are fixed with bolts to complete the clamping work of the splitting device 300. When it is necessary to adjust the splitting device 300, the height of the splitting device 300 in the spinning thread washing tank is adjusted by turning the adjusting rod 4. Loosening the bolts on the upper clamping member 21 and the lower clamping member 22 allows the splitting device 300 to be rotated in the clamping position 27 of the clamp 2 to change the working surface of the splitting device 300. After adjusting the working position, the bolts on the upper clamping member 21 and the lower clamping member 22 are tightened to complete the adjustment. Furthermore, the height-adjustable clamping device 100 can adjust the height of the clamp 2 at any time during the production process according to different production conditions, thereby ensuring that the wire splitting device 300 is at a suitable working height to meet production requirements.

[0051] Furthermore, the clamping position 27 of the clamp 2 is located between the adjusting rod 4 and the guide through hole 24 of the clamp 2.

[0052] Furthermore, the adjusting rod 4 is positioned at the center of the clamp 2.

[0053] In the above embodiment, the substrate 1 is a square plate, and both the upper clamping member 21 and the lower clamping member 22 are square plates. The longitudinal projections of the substrate 1, the upper clamping member 21, and the lower clamping member 22 coincide. The clamping position 27 is located adjacent to the adjusting rod 4, and two clamping positions 27 are symmetrically arranged on the clamp 2, respectively located on both sides of the adjusting rod 4. The two clamping positions 27, which are located adjacent to and symmetrically arranged close to the adjusting rod 4, can minimize the deformation of the clamping positions 27 caused by the movement of the upper clamping member 21 and the lower clamping member 22 when they move together, thereby more accurately separating and clamping the carbon fiber filaments 600 on both sides of the adjusting rod 4.

[0054] like Figure 2 As shown, a buried hole 11 is further provided at the center of the substrate 1. The buried hole 11 matches the rod tail structure of the adjusting rod 4. The buried hole 11 is used to limit the rotation of the adjusting rod 4 on the substrate 1.

[0055] like Figure 5As shown, this utility model also discloses a spinning yarn washing tank, including: a washing tank body 200, and a height-adjustable clamping device 100 as described in any of the preceding embodiments. The height-adjustable clamping device 100 is set at a preset position of the washing tank body 200. The yarn separating device 300 has a rod-shaped structure. The middle part of the yarn separating device 300 has multiple yarn separating grooves 400 or yarn separating holes. Both ends of the yarn separating device 300 are matched with the clamping position 27 of the clamp 2. The yarn separating device 300 is height-adjustable inside the washing tank body 200 through the height-adjustable clamping device 100.

[0056] In this embodiment, a winding roller 500 is arranged along the preset travel direction of the carbon fiber filament 600. The roller 500 is at least located at both ends of the washing tank body 200. Multiple carbon fiber filaments 600 travel along the preset travel direction to the washing tank body 200 and are immersed in hot water. Multiple carbon fiber filaments 600 pass through the splitting groove 400 / splitting hole of the splitting device 300 to avoid tangling. Those skilled in the art can use tools to twist the adjustable clamping device 100 located at both ends of the splitting device 300 to adjust the rise and fall of the splitting device 300 during the production process.

[0057] Specifically, the preset position of the adjustable clamp device 100 can be set on the bottom side wall of the washing tank body 200, and the position of each adjustable clamp device 100 is close to the four sides of the washing tank body 200.

[0058] Preferably, the height-adjustable clamping device 100 is located on both sides of the carbon fiber precursor 600 in the preset travel direction.

[0059] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
