Description

Technical Field

[0001] This utility model relates to the field of graphite, and in particular to a graphite twisting device. Background Technology

[0002] Graphite twisted yarn likely refers to graphite yarn that has undergone a twisting process. Twisting is a process designed to increase the density of the raw yarn. For twisted strands, in addition to increasing density, it can also change the package shape and linear density to meet the requirements of subsequent processing and use. Graphite yarn itself is made of expanded graphite, various fibers, metal wires, and adhesives, and possesses a certain degree of flexibility and braiding ability, making it suitable for weaving different types of flexible graphite braided fillers.

[0003] Graphite, as a material, possesses excellent electrical conductivity, high-temperature resistance, and corrosion resistance. Therefore, graphite twisted wire combines the properties of graphite with the advantages of twisting technology, resulting in superior performance and applicability in certain specific applications. For example, in power systems, graphite materials are used as grounding materials due to their excellent electrical conductivity and chemical stability. Graphite twisted wire, with its compact structure and flexible properties, can better adapt to soil variations, ensuring a good fit between the grounding grid and the soil, thereby reducing grounding resistance and improving the safety of the grounding system.

[0004] There is a graphite twisting device in the prior art that can twist graphite strips into graphite threads, such as Chinese Patent Application No. CN201320113623.0. This utility model discloses a graphite twisting device, which includes a winding device, a twisting device, a clutch device, a power device, and a frame. The winding device is located above the frame, the twisting device is located below the winding device, the clutch device is located below the twisting device, and the power device is located on one side of the frame. In use, the twisting spindle is placed on the twisting shaft, and the twisting spindle is locked. The graphite wire is then passed through the forming mold and connected to the take-up reel via a twister. The power unit is then started, and the twisting device, connected to the power supply via a clutch, rotates at high speed to begin twisting the wire. The graphite strip is twisted into graphite wire through the forming mold. The smoothness and uniformity of the twisted wire are adjusted by changing the speed of the twister. When it is necessary to replace the twisting spindle, the clutch pedal is pressed to disengage the clutch, and the take-up reel is lifted. The twisting spindle is then replaced, and the replacement is completed by releasing the clutch pedal and lowering the take-up reel. This method is safe, practical, and worthy of promotion and application.

[0005] However, the aforementioned prior art has the following shortcomings: 1. The twisting spindle, i.e., the spool of the present invention, is disassembled via the twisting spindle switch. However, the disassembly of the twisting spindle is not described in the present invention. It can be seen from the accompanying drawings that a mounting shaft is coaxially arranged at the center of the spool. After the twisting spindle switch is pulled out and the mounting shaft is removed, the spool has no support. If there is no second operator, the spool will fall out of the mounting frame, which may easily damage the spool or other parts of the device. 2. The device does not have protective measures against debris generated during twisting. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a graphite twisting device, which solves the following issues in the prior art: 1. The twisting spindle, i.e., the spool described in this utility model, is disassembled via a twisting spindle switch. However, the disassembly of the twisting spindle is not described in the utility model. It can be seen from the accompanying drawings that a mounting shaft is coaxially arranged at the center of the spool. After the twisting spindle switch is pulled out and the mounting shaft is removed, the spool has no support. If there is no second operator, the spool will fall out of the mounting frame, easily damaging the spool or other parts of the device. 2. The device does not have protective measures against debris generated during twisting.

[0007] A graphite twisting device includes a pair of horizontally arranged and parallel take-up rollers, a take-up drum is mounted between the pair of take-up rollers, and the pair of take-up rollers rotating in the same direction can drive the take-up drum to rotate. It also includes a horizontally arranged mounting base, and a mounting frame for mounting a spool is provided above the mounting base.

[0008] The mounting frame is divided into two parts: Frame 1 and Frame 2. A quick-installation mechanism is provided between Frame 1 and Frame 2, which allows Frame 2 to be quickly installed onto Frame 1 to form a complete mounting frame. Frame 2 is provided with a release mechanism, which can be triggered to remove Frame 2 from Frame 1. Frame 2 is also provided with a mounting shaft parallel to the top surface of the mounting base. The mounting shaft is provided with a locking mechanism. A wire spool is coaxially mounted on the mounting shaft, and a mounting hole is provided at the center of the wire spool.

The wire spool can rotate within the mounting frame about an axis perpendicular to the spool surface and passing through the center of the spool. The mounting base is also provided with a driving device to rotate the mounting frame, and the mounting frame drives the wire spool to rotate simultaneously about the axis of symmetry of the spool surface.

[0009] The upper side of the mounting frame is also provided with a twisting spool. After the graphite wire passes through the twisting spool, it is wound onto the take-up spool. The twisting spool can reduce the friction of graphite in the twisting spool. A debris collection device is provided on one side of the twisting spool. The debris collection device can collect the debris generated by the friction of graphite.

[0010] Furthermore, the mounting frame is a rectangular frame as a whole, and the first frame and the second frame are two parts divided vertically from the rectangular frame. The upper and lower end faces of the first and second frames are provided with mutually cooperating quick-installation mechanisms.

[0011] Furthermore, the quick-installation mechanism includes mounting blocks fixedly connected to both sides of the upper and lower end faces of the frame part. Each mounting block has an insertion hole, the axis of which is parallel to the plane of the mounting frame and perpendicular to the vertical axis of symmetry of the entire mounting frame. A locking hole is formed in the insertion hole, moving away from the insertion hole axis. A pair of mounting pins are provided on both sides of the upper and lower end faces of the frame part, coaxially insertable into the insertion hole. A pair of blind holes are formed on both sides of each mounting pin, the axis of which is perpendicular to the axis of the mounting pin. A spring block is movably disposed inside each blind hole. A spring is disposed between the spring block and the inner end face of the blind hole, ejecting the spring block from the blind hole. A first flange protruding perpendicularly to the axis of the blind hole is provided at the opening of the blind hole, locking the spring block so that only a portion protrudes outside the blind hole. When the spring block contacts the flange, it retracts into the mounting plug. After the mounting plug is fully inserted into the insertion hole, the spring block ejects and inserts into the locking hole, locking the frame part onto the frame part.

[0012] Furthermore, the release mechanism includes a wire hole that passes through the mounting pin. One end of the wire hole is located at the end of the mounting pin away from the inner end face of the insertion hole, and the other end is located at the inner end face of the blind hole. A pull wire is provided in the wire hole. One end of the pull wire is fixedly connected to the end of the spring block near the end face of the blind hole. A handle is provided on the side of the mounting pin away from the inner end face of the insertion hole. A handle is provided on the upper and lower sides of the second part of the frame. The pull wire is fixedly connected to the handle. Pulling the handle can retract the spring block into the blind hole, thereby allowing the mounting pin to be pulled out of the insertion hole.

[0013] Furthermore, the twisting spool is disposed on the upper end face of the frame part, the axis of the twisting spool is perpendicular to the top surface of the mounting base, and the twisting spool is coaxially provided with a twisting hole, and an anti-wear cylinder is coaxially provided in the twisting hole. The anti-wear cylinder can rotate in the twisting spool about the axis of the twisting spool, and the two ends of the anti-wear cylinder in the vertical direction are rounded.

[0014] Furthermore, a rotating shaft is coaxially arranged on the lower side of the mounting frame and the twisting spool, and the driving device is a drive motor, the output shaft of the drive motor being coaxially connected to the rotating shaft.

[0015] Furthermore, the debris collection device includes a dust-collecting ring sleeved on the upper side of the twisting spool. The dust-collecting ring can suck away the debris generated on the twisting spool, preventing the debris from falling into the twisting spool and affecting the twisting effect.

[0016] Furthermore, the locking mechanism includes a second flange on the mounting shaft, the second flange protruding outward perpendicular to the axis of the mounting shaft. The end face of the mounting shaft away from the second part of the frame has a threaded hole coaxially. A limiting sub-shaft is provided on the first part of the frame. The limiting sub-shaft is coaxial with the mounting shaft and has a third flange on it. The third flange protrudes outward perpendicular to the axis of the limiting sub-shaft. The second flange and the third flange cooperate to fix the coil and prevent the coil from shifting and rubbing against the mounting frame during rotation. The limiting sub-shaft has a threadless fixing through hole coaxially. The fixing through hole passes through the frame and the limiting sub-shaft. A fourth flange protruding perpendicularly to the axis is provided on the side of the fixing through hole near the mounting shaft. A bolt is provided in the through hole and can be screwed into the threaded hole to further fix the mounting shaft.

[0017] This utility model has the following advantages: Addressing the problem of inconvenient reel disassembly, this utility model divides the mounting frame into two parts, with the mounting shaft positioned on the second part. A quick-release mechanism is provided between the first and second parts. During installation, the reel is simply placed on the mounting shaft, and then the second part is installed onto the first part. A locking mechanism further secures the mounting shaft and the limiting sub-shaft, completing the assembly of the entire mounting frame. Disassembly simply requires removing the bolts and pulling the handle to remove the second part, allowing the empty reel to be removed. Regarding the lack of protective measures against debris generated during twisting, this device incorporates a dust-collecting ring around the outer circumference of the twisting drum, which sucks in debris, reducing its impact on the twisting effect.

Detailed Implementation

[0026] The present invention will now be described with reference to the accompanying drawings:

[0027] like Figure 1 As shown, a graphite twisting device includes a pair of horizontally arranged and parallel take-up rollers 1, a take-up drum 2 is mounted between the pair of take-up rollers, and the pair of take-up rollers 1 can rotate in the same direction to drive the take-up drum 2 to rotate. It also includes a horizontally arranged mounting base 3, and a mounting frame 4 for mounting a spool 5 is provided above the mounting base 3.

[0028] like Figure 1 and Figure 6 As shown, the mounting frame 4 is divided into two parts: a first frame 41 and a second frame 42. A quick-installation mechanism is provided between the first frame 41 and the second frame 42, allowing the second frame 42 to be quickly installed onto the first frame 41 to form a complete mounting frame 4. The second frame 42 is equipped with a release mechanism, which can be triggered to remove the second frame 42 from the first frame 41. The second frame 42 is also equipped with a mounting shaft 43 parallel to the top surface of the mounting base, and a locking mechanism is provided on the mounting shaft 43. A coil 5 is coaxially mounted on the mounting shaft 43. A mounting hole 51 is provided at the center of the coil 5. The coil 5 can be coaxially mounted to the mounting shaft 43 through the mounting shaft 51. The coil 5 is located between the first frame 41 and the second frame 42. The end face of the coil 5 is perpendicular to the top surface of the mounting base 3. The coil 5 can rotate in the mounting frame 4 with an axis perpendicular to the coil surface and passing through the center of the coil. The mounting base 3 is also provided with a driving device to rotate the mounting frame 4. The mounting frame 4 drives the coil 5 to rotate simultaneously with the axis of symmetry of the coil surface.

[0029] like Figure 1 and Figure 3 As shown, a twisting spool 411 is also provided on the upper side of the mounting frame 4. After the graphite thread passes through the twisting spool 411, it is wound on the take-up spool 2. The twisting spool 411 can reduce the friction of graphite in the twisting spool 411, and a debris collection device is provided on one side of the twisting spool 411. The debris collection device can collect the debris generated by the friction of graphite.

[0030] like Figure 1 As shown, preferably, the mounting frame 4 is a rectangular frame as a whole, and the first part 41 and the second part 42 are two parts divided into the rectangular frame along the vertical direction. The upper and lower end faces of the first part 41 and the second part 42 are provided with mutually cooperating quick-installation mechanisms.

[0031] like Figure 1 , Figure 2 As shown, preferably, the quick-installation mechanism includes mounting blocks 414 fixedly connected to both sides of the upper and lower end faces of the frame part 41. Each mounting block 414 has an insertion hole 415. The axis of the insertion hole 415 is parallel to the plane containing the mounting frame 4 and perpendicular to the vertical axis of symmetry of the entire mounting frame 4. Each insertion hole 415 has a locking hole 416 extending away from the axis of the insertion hole 415. A pair of mounting pins 417 are provided on both sides of the upper and lower end faces of the frame part 42. Each mounting pin 417 can be coaxially inserted into the insertion hole 415. Each mounting pin 417 has a pair of blind holes 418 on both sides, with the axes of the pair of blind holes 418 perpendicular to the mounting pin 417. A spring block 4191 is movably disposed inside the blind hole 418. A spring 419 is disposed between the spring block 4191 and the inner end face of the blind hole 418. The spring 419 ejects the spring block 4191 out of the blind hole 418. A first flange 420 is disposed at the opening of the blind hole 418, protruding perpendicularly to the axis of the blind hole 418. The first flange 420 holds the spring block 4191 in place, so that the spring block 4191 can only protrude a part outside the blind hole 418. When the spring block 4191 contacts the flange, it retracts into the mounting plug. After the mounting plug is fully inserted into the socket 415, the spring block 4191 pops out and inserts into the locking hole 416, so that the second part of the frame 42 is locked onto the first part of the frame 41.

[0032] like Figure 2 , Figure 7 As shown, preferably, the release mechanism includes a wire hole 421 that passes through the mounting pin 417. One end of the wire hole 421 is open at the end of the mounting pin 417 away from the inner end face of the insertion hole 415, and the other end is located at the inner end face of the blind hole 418. A pull wire 422 is provided in the wire hole 421. One end of the pull wire 422 is fixedly connected to the end of the spring block 4191 near the end face of the blind hole 418. A handle 423 is provided on one side of the inner end face of the mounting pin 41751. (Frame 2) A handle 423 is provided on the upper and lower sides of part 42, and the pull wire 422 is fixedly connected to the handle 423. Pulling the handle 423 can retract the spring block 4191 into the blind hole 418, thereby allowing the mounting pin 417 to be pulled out from the insertion hole 415. It should be noted that the handle 423 is made of lightweight material, and the dynamic potential energy generated after the mounting frame 4 rotates is much less than the pressure applied to the spring block 4191 by the spring 419, and will not affect the fixation of the mounting frame 4.

[0033] like Figure 1 , Figure 7 , Figure 3 As shown, preferably, the twisting spool 411 is disposed on the upper end face of the frame part 41. The axis of the twisting spool 411 is perpendicular to the top surface of the mounting base 3, and the twisting spool 411 is coaxially provided with a twisting hole 413. An anti-wear cylinder 412 is coaxially provided in the twisting hole 413. The anti-wear cylinder 412 can rotate in the twisting spool 411 about the axis of the twisting spool 411, and the two ends of the anti-wear cylinder 412 in the vertical direction are rounded.

[0034] like Figure 1 As shown, preferably, a rotating shaft 424 is coaxially arranged on the lower side of the mounting frame 4 and the twisting spool 411. The driving device is a drive motor 425, and the output shaft of the drive motor 425 is coaxially connected to the rotating shaft 424.

[0035] like Figure 1 , Figure 4 Preferably, the debris collection device includes a dust-collecting ring 6 sleeved on the upper side of the twisting spool 411. The dust-collecting ring 6 can suck away the debris generated on the twisting spool 411, preventing the debris from falling into the twisting spool 411 and affecting the twisting effect.

[0036] like Figure 1 , Figure 5 As shown, preferably, the locking mechanism includes a second flange 426 provided on the mounting shaft 43, the second flange 426 protruding outward perpendicular to the axis of the mounting shaft 43, a threaded hole 427 coaxially formed on the end face of the mounting shaft 43 away from the frame part 42, a limiting sub-shaft 44 provided on the frame part 41, the limiting sub-shaft 44 being coaxial with the mounting shaft 43, and a third flange 441 provided on the limiting sub-shaft 44, the third flange 441 protruding outward perpendicular to the axis of the limiting sub-shaft 44, the second flange 426 and the third flange 441 being able to cooperate to... The wire spool 5 is fixed to prevent it from shifting and rubbing against the mounting frame 4 during rotation. The limiting sub-shaft 44 is coaxially provided with a threadless fixing through hole 442. The fixing through hole 442 passes through the frame and the limiting sub-shaft 44. A fourth flange 443 protruding vertically to the axis is provided on the side of the fixing through hole 442 near the mounting shaft 43. The fourth flange 443 serves to reduce the diameter of the hole and hold the bolt 444. The bolt 444 is provided in the through hole and can be screwed into the threaded hole 427 to further fix the mounting shaft 43.

[0037] It should be noted that this device also requires the use of a twister 11, which is existing technology and therefore has not been described in detail.

[0038] The method of using this utility model is as follows: The mounting frame 4 is divided into a first frame 41 and a second frame 42. The mounting shaft 43 is set on the second frame 42, and a quick-installation mechanism is set between the first frame 41 and the second frame 42. During installation, the spool 5 only needs to be put on the mounting shaft 43, and then the second frame 42 is installed on the first frame 41. Then, the mounting shaft 43 and the limiting sub-shaft 44 are further fixed by the locking mechanism, thus completing the assembly of the entire mounting frame 4. During disassembly, the bolts 444 only need to be removed, and the handle 423 can be pulled to remove the second frame 42, thereby allowing the empty spool 5 to be removed. In view of the problem that the device does not have protective measures for the debris generated during twisting, this device can suck up the debris by putting a dust suction ring 6 around the outside of the twisting spool 411, reducing the impact of debris on the twisting effect.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
