Description

Technical Field

[0001] This utility model belongs to the technical field of equipment for carbon fiber rod processing, and specifically relates to a carbon cloth bonding and rolling integrated machine for carbon fiber rod processing. Background Technology

[0002] In the processing of carbon fiber rods (such as fishing rods and arrow shafts), a release agent needs to be applied to the surface of the mandrel (mold). The cut carbon fiber cloth is then laid on the mandrel according to the designed sequence and rolled up. The rolled mandrel is placed in a curing oven and heated and cured at a set temperature (usually 80-120℃) for a set time, causing the resin to cross-link and form a carbon fiber rod blank. In existing technologies, to ensure the carbon fiber cloth bonds to the mandrel, adhesive is applied to the carbon cloth or mandrel, and then the joint between the carbon fiber cloth and the rod is ironed flat manually or mechanically. After the carbon cloth and mandrel are fixed, the rod is rolled up. The applicant has improved the rolling process of the carbon fiber cloth and mandrel by adding a low-melting-point adhesive to the release agent. The low-melting-point adhesive is applied to the mandrel together with the release agent, eliminating the need for separate adhesive application to the carbon cloth or mandrel, thus simplifying the rolling process. However, existing equipment cannot achieve integrated production of the carbon cloth rolling to the mandrel, thus limiting the processing efficiency of the carbon fiber rod. Utility Model Content

[0048] See Figure 1 A carbon fiber rod processing machine for bonding and rolling carbon fiber fabric includes a core mold feeding device 1, a carbon fiber feeding device 2, a bonding and ironing device 3, and a winding device 4. The core mold feeding device 1 feeds a core mold containing molten adhesive to the bonding and ironing device 3; the carbon fiber feeding device 2 feeds carbon fiber fabric to the bonding and ironing device 3; the bonding and ironing device 3 receives the core mold, removes the carbon fiber fabric from the carbon fiber feeding device 2, bonds the carbon fiber fabric to the core mold, and transfers the carbon fiber-bonded core mold to the winding device 4; the winding device 4 winds the carbon fiber fabric onto the core mold.

[0049] See the structure of core mold feeding device 1. Figures 2-6 The core mold feeding device 1 includes a first frame 11 and a core mold placement mechanism 13 mounted on the first frame 11. The core mold placement mechanism 13 includes a conveyor belt 131 with baffles 132 and three sets of conveyor belt pulleys 133 supporting the conveyor belt 131. The conveyor belt pulleys 133 are triangularly distributed. The conveyor belt 131 mounted on the conveyor belt pulleys 133 has an inclined section 1311 and a horizontal section 1312. The last conveyor belt pulley 133 of the horizontal section 1312 is connected to a drive motor 134. A core mold guide plate 12 is mounted on the first frame 11 at the end of the horizontal section 1312. The baffles 132 are arranged in parallel on the conveyor belt 131, creating multiple conveying stations. A low-temperature heating furnace 14 is mounted above the horizontal section 1312 to heat the core mold of the horizontal section 1312. The low-temperature heating furnace 14 can be a low-temperature tunnel furnace, which has low processing costs and can meet the requirements for melting low-melting-point colloids.

[0050] A support plate 135, which is horizontal to the conveyor belt 131, is provided on the first frame 11 on one side of the horizontal section 1312 of the conveyor belt 131. The support plate 135 supports the end of the long core mold 100, so that the core mold placement mechanism 13 can accommodate a wider range of core molds.

[0051] A screening mechanism 16 is installed on the first frame 11 on both sides of the inclined section 1311 of the conveyor belt pulley 133. The screening mechanism 16 includes a screening adjustment plate 161 and an adjustment module 162. The screening adjustment plate 161 is connected to the slider of the adjustment module 162. The screening adjustment plate 161 is provided with multiple V-shaped grooves. The mandrel falling into the V-shaped groove can enter between the baffles 132 of the conveyor belt 131 and move towards the horizontal section 1312 under the push of the baffles 132, while the mandrel that does not fall into the V-shaped groove falls into the hopper of the feeding mechanism. The position of the screening adjustment plate 161 can be adjusted by the adjustment module 162. The adjustment module 162 includes a lead screw 1621 and a module slider 1622. The screening adjustment plate 161 is connected to the module slider 1622. By rotating the lead screw 1621 through the handwheel 1623, the module slider 1622 is driven to move, thereby adjusting the position of the screening adjustment plate 161 so that the position of the V-groove matches the rods of different thicknesses.

[0052] The core mold placement mechanism 13 has a core mold feeding mechanism 15 on its front side for feeding core molds to the core mold placement mechanism 13. The core mold feeding mechanism 15 includes an inclined material bin bottom plate 151, a fixed plate 152 that is separate from or integrated with the material bin bottom plate 151, and an adjustable plate 153 that is separate from the material bin bottom plate 151.

The adjustable plate 153 includes an adjustable side plate 1531 and an adjustable bottom plate 1532. The fixed bottom plate 1522 and the adjustable bottom plate 1532 are both parallel to the material bin bottom plate 151. A material distribution plate 154 is provided on the inner wall of the fixed side plate 1521 and the adjustable side plate 1531. There is a gap 155 between the material distribution plate 154 and the fixed bottom plate 1522 and the adjustable bottom plate 1532 for the core mold to pass through. The adjustable plate 153 is connected to the side plate slider 156, which moves along the side plate slide rail 157. The position of the side plate slider 156 on the side plate slide rail 157 is adjusted according to the length of the core mold 100, thereby adjusting the distance between the adjustable plate 153 and the fixed side plate 1521 to meet the feeding needs of core molds of different lengths. The core mold 100 placed on the bottom plate 151 of the hopper can move along the inclined plane towards the core mold placement mechanism 13. The inner walls of the fixed side plate 1521 and the adjustable side plate 1531 are provided with a distribution plate 154 to block the sliding core molds. Only a small number of core molds can pass through the gap 155 between the distribution plate 154 and the fixed bottom plate 1522 and the adjustable bottom plate 1532, avoiding a large number of core molds from reaching the conveyor belt 131 at the same time and affecting normal screening and feeding.

[0053] See the structure of carbon cloth feeding device 2. Figures 7-13 The carbon fiber feeding device 2 includes a second frame 21, a hopper mechanism 22, a secondary positioning mechanism 24, and a carbon fiber transfer mechanism 23 mounted on the second frame 21. The secondary positioning mechanism 24 is located behind the hopper mechanism 22, and the carbon fiber transfer mechanism 23 is located above the hopper mechanism 22 and the secondary positioning mechanism 24, transferring the carbon fiber from the hopper mechanism 22 to the secondary positioning mechanism 24 for secondary positioning. (See also...) Figure 9The hopper mechanism 22 includes a fixed base plate 2201 fixed to the second frame 21 and a movable tray 2202 located above the fixed base plate 2201 for placing carbon fiber. A rear positioning block 2205 is provided on the rear side of the movable tray 2202. Fixed side plates 2206 and movable side plates 2207 are respectively provided on the left and right sides of the movable tray 2202. An clearance groove 2203 is provided on the movable tray 2202. A limiting rod 2210 located on the front side of the movable tray 2202 moves back and forth within the clearance groove 2203. The position of the movable side plate 2207 is adjusted according to the length of the carbon fiber to limit the left and right ends of the carbon fiber by the fixed side plates 2206 and the movable side plates 2207. The position of the limiting rod 2210 in the clearance groove 2203 is adjusted to limit the front and rear ends of the carbon fiber by the rear fixing block and the limiting rod 2210, ensuring that the carbon fiber is neatly placed on the movable tray 2202. As a preferred embodiment, upper limit blocks 2209 are respectively provided above the fixed side plate 2206 and the movable side plate 2207. The upper limit blocks 2209 restrict the two ends of the upper carbon cloth on the movable tray 2202. When the carbon cloth transfer mechanism 23 removes the carbon cloth, the uppermost carbon cloth can be separated from the upper limit blocks 2209, and the lower carbon cloth is restricted from being picked up by the carbon cloth transfer mechanism 23 together with the uppermost carbon cloth, ensuring that one piece of carbon cloth is removed each time.

[0054] Photoelectric sensors 2212 are respectively installed on the fixed side plate 2206 and the movable side plate 2207. The two photoelectric sensors 2212 receive signals through a beam. The carbon cloth on the movable tray 2202 is located between the two photoelectric sensors 2212. When the photoelectric sensor 2212 that receives the signal through a beam receives the signal, the top layer of carbon cloth on the movable tray 2202 is not in place, and the movable tray 2202 needs to be moved up. When there is no signal between the two, the top layer of carbon cloth on the movable tray 2202 is in place, and the carbon cloth transfer mechanism 23 can perform the transfer action to ensure the accuracy of the transfer.

[0055] The limiting rod 2210 is mounted on the switchable magnetic base 2211, which is placed on the fixed base plate 2201. The position of the limiting rod 2210 can be quickly adjusted using the switchable magnetic base 2211 to meet the needs of limiting carbon cloth of different specifications.

[0056] The fixed base plate 2201 is provided with a rear plate 2213, which has at least two sets of vertical guide rails 2214. The movable tray 2202 is provided with a tray slider 2204 that cooperates with the vertical guide rails 2214, and the movable tray 2202 can be driven by a synchronous belt to move up and down along the vertical guide rails. The rear plate 2213 is provided with a transverse guide rail 2215, and the movable side plate 2207 is connected to the side plate slider 2208. The side plate slider 2208 moves along the transverse rail, and the position of the movable side plate 2207 is adjusted according to the length of the carbon cloth.

[0057] See Figure 10 and Figure 11 The carbon fiber transfer mechanism 23 includes a shifting slide rail 2301 mounted on a second frame 21, a shifting slider 2302 mounted on a slider fixing plate 2303 and moving along the shifting slide rail 2301, a first lifting cylinder 2304 fixed to the lower end of the slider fixing plate 2303, a mounting plate 2305 connected to the first lifting cylinder 2304, and several suction cup fixing plates 2306 mounted on the mounting plate 2305. The suction cup fixing plate 2306 is provided with position-adjustable suction cups 2309. In this embodiment, the suction cup fixing plate 2306 is provided with a suction cup fixing groove 2307, and a suction cup mounting seat 2308 is fixed to the fixing groove by a limiting screw 2310. The position of the suction cup mounting seat 2308 in the fixing groove can be adjusted according to the width of the carbon fiber, so that the spacing of the suction cups 2309 meets the requirements of carbon fiber of different widths.

[0058] See Figure 12 and Figure 13 The secondary positioning mechanism 24 includes a secondary positioning plate 2401, a positioning and alignment plate A2406, and a positioning and alignment plate B2407. A left fixed limiting block 2404 and a rear fixed limiting block 2405 are respectively provided on the left and rear sides of the secondary positioning plate 2401. A alignment groove A2402 extending along the length direction of the secondary positioning plate 2401 is provided on the right side of the secondary positioning plate 2401. A alignment groove B2403 extending along the width direction of the secondary positioning plate 2401 is provided between the alignment groove A2402 and the left fixed limiting block 2404. The positioning and alignment plates A2406 and B2407 move along the alignment grooves A2402 and B2403 respectively, pushing the carbon cloth on the secondary positioning plate 2401 to move towards the left fixed limiting block 2404 and the rear fixed limiting block 2405 for secondary positioning. Fiber optic sensors 2408 are respectively installed at the left fixed limiting block 2404 and the rear fixed limiting block 2405. The carbon cloth is aligned by the positioning and straightening plates A2406 and B2407. When the carbon cloth reaches its position, the fiber optic sensors 2408 at both the left fixed limiting block 2404 and the rear fixed limiting block 2405 output signals, indicating that the carbon cloth has reached its designated position. The movement of the positioning and straightening plates A2406 and B2407 can be driven by linear modules 2409 and 2410, respectively.

[0059] See Figures 14-18The heat-pressing integrated device 3 includes a third frame 31 and a work platform 32 set on the third frame 31. The work platform 32 has a core mold transfer assembly 33 for moving the core mold on the left and right sides. The work platform 32 has a core mold limiting plate 323 and a heat-pressing core base plate 325 arranged sequentially from front to back. The core mold limiting plate 323 and the heat-pressing core base plate 325 are respectively provided with a cloth-applying mechanism 34 and a cloth-pressing mechanism 35. The cloth-applying mechanism 34 applies the transferred carbon cloth to the core mold located at the core mold limiting plate 323 on the work platform. The cloth-pressing mechanism 35 further presses the core mold 100 and carbon cloth 200 placed on the heat-pressing core base plate 325 to prepare for the tube rolling machine.

[0060] The core mold limiting plate 323 is provided with magnet mounting grooves 3231 in sections. Magnets 324 are assembled in the magnet mounting grooves 3231. Magnets 324 can keep the core mold position fixed when the core mold placed on the working platform 32 is attached to the core mold limiting plate 323 and when the carbon cloth is attached by the cloth attaching mechanism 34.

[0061] The applicator 34 includes an applicator base 342 with a plurality of suction nozzles 341 and an applicator moving component 343 for adjusting the position of the applicator base 342. The applicator moving component 343 includes an X-axis shifting component 3431 for adjusting the left and right position of the applicator base 342 and a Y-axis shifting component 3432 for adjusting the up and down position. The X-axis shifting assembly 3431 includes an X-axis slide rail 34311 and an X-axis slider 34312 mounted on the X-axis slide rail 34311. The X-axis slider 34312 is driven by a synchronous belt to move along the X-axis slide rail 34311. The Y-axis shifting assembly 3432 includes a lead screw assembly 34321. A slide block 34322 connected to the lead screw nut is connected to the fabric application base 342. The lead screw is driven by a motor 34323 to rotate, thereby causing the fabric application base 342 to move up and down. The lead screw assembly 34321 is connected to a lifting and fixing plate 34324, which is connected to the X-axis slider 34312. After the suction nozzle 341 on the fabric application base 342 picks up the carbon cloth, it reaches above the core mold limiting plate 323 under the action of the X-axis shifting assembly 3431, and moves downward under the action of the Y-axis shifting assembly 3432, thus attaching the carbon cloth to the core mold. The core mold transfer assembly 33 moves the core mold backward to the hot iron base plate 325, waiting for the fabric pressing operation.

[0062] In this embodiment, a core mold positioning groove 3251 is provided on the hot stamping core base plate 325. The core mold positioning groove 3251 is V-shaped, which can accommodate core molds of different thicknesses. The pressing mechanism 35 includes a connecting plate 352 and a pressing plate 353. The connecting plate 352 is connected to the second lifting cylinder 351, and the pressing plate 353 is located below the connecting plate 352. A silicone pad 354 is provided on the lower surface of the pressing plate 353. A heating rod 355 is provided inside the pressing plate 353. Driven by the second lifting cylinder 351, the pressing plate 353 moves downward, and the silicone pad 354 directly contacts the core mold in the core mold positioning groove 3251, pressing the carbon cloth and the core mold tightly. The bonding force between the carbon cloth and the backing paper is relatively weak, and the backing paper separates from the carbon cloth at the joint between the carbon cloth and the adhesive core mold.

[0063] To improve the compatibility of the heat-sealing machine with mandrels of different lengths, the working platform 32 includes a main worktable 321 and a secondary worktable 322, which are independent of each other. The secondary worktable 322 is detachably connected to the third frame 31. The mandrel limiting plate 323 and the heat-sealing base plate 325, which are set on the main worktable 321 and the secondary worktable 322, are separated and extend in the X-direction. The mandrel limiting plate 323 and the heat-sealing base plate 325 on the secondary worktable 322 are removed together with the secondary worktable 322 to avoid affecting the mandrel transfer assembly 33's transfer of the mandrel. Disassembling the secondary worktable 322 can accommodate the process of pressing short carbon fiber cloth onto the mandrel, while adding the secondary worktable 322 can meet the process of pressing long carbon fiber cloth onto long mandrels. It can be flexibly assembled as needed.

[0064] The core mold transfer assembly 33 includes two sets of parallel transfer plates 331. The transfer plates 331 move back and forth under the drive of the Z-axis shifting assembly 333 and move up and down under the drive of the Y-axis transfer assembly 332. The Z-axis shifting assembly 333 can be implemented using a lead screw module, and the Y-axis transfer assembly 332 can be implemented using a cylinder. One set of the two sets of transfer plates 331 is fixed in the X-axis position, while the other set is adjustable in the X-axis position. The Z-axis shifting assembly 333 on the adjusting side is mounted on an adjusting slider 334. The adjusting slider 334 moves along an adjusting slide rail 335, and its position on the adjusting slide rail 335 is adjusted according to the length of the core mold to ensure a suitable distance between the transfer plates 331, thus supporting both ends of the core mold 100.

[0065] The front side of the working platform 32 is provided with a receiving assembly 38 for receiving the core molds fed by the core mold feeding device 1. The receiving assembly 38 includes at least two sets of receiving blocks 381, and the receiving blocks 381 are driven to move up and down by receiving cylinders 382. A limit baffle 36 is provided on the outside of the fixed side transfer plate 331, and an alignment mechanism 37 is provided on the outside of the moving side transfer plate 331. The alignment mechanism 37 includes an alignment push plate 371 and an alignment cylinder 372. The alignment cylinder 372 drives the alignment push plate 371 to move and align the core molds on the receiving blocks 381 towards the limit baffle 36.

[0066] A core mold transfer mechanism 39 is provided on the rear side of the work platform 32. The core mold transfer mechanism 39 transfers the core mold pressed with carbon cloth to the tube winding device 4. The core mold transfer mechanism 39 includes two parallel gripper cylinders 391. The gripper cylinders 391 are connected to the gripper lifting cylinders 393. The gripper lifting cylinders 393 drive the gripper cylinders 391 to move up and down. The gripper lifting cylinders 393 are connected to the Z-axis linear module 392. The Z-axis linear module 392 drives the gripper lifting cylinders 393 to move back and forth.

[0067] See the structure of the tube winding device 4. Figures 19-22 The tube winding device 4 includes a fourth frame 41, an upper pressure plate 42 that can move up and down on the fourth frame 41, and a lower support plate 44 that can move back and forth on the fourth frame 41. The upper pressure plate 42 is located above the lower support plate 44. A back paper blowing mechanism 46 and a lifting lever mechanism 47 are arranged in front of the upper pressure plate 42. A conveyor line mechanism that moves synchronously with the lower support plate 44 is arranged at the rear end of the lower support plate 44. The conveyor line mechanism includes a rod conveying device 48 and a back paper conveying device 49. The core mold after tube winding is moved to the rod conveying device 48 by the lever mechanism 47, and the back paper blowing mechanism 46 blows the back paper onto the back paper conveying device 49. The up and down movement of the upper pressure plate 42 can be driven by a cylinder. An upper pressure plate cylinder 43 that drives the upper pressure plate 42 to move up and down is vertically installed on the fourth frame 41. The piston rod of the upper pressure plate cylinder 43 is connected to the upper pressure plate 42. The forward and backward movement of the lower support plate 44 is driven by the lower support plate shifting mechanism 45. The lower support plate shifting mechanism 45 can be a lead screw. A lower support plate slider 451 is provided below the lower support plate 44. A guide rail is provided on the fourth frame 41. The lower support plate slider 451 moves along the guide rail. The lead screw 453 is connected to the lower support plate 44 via a lead screw connecting plate 454. The motor drives the lead screw 453 to rotate via a belt, thereby causing the lower support plate 44 to move forward and backward along the guide rail 452. The lower support plate 44 moves forward and is misaligned with the upper pressure plate 42. The core mold gripping mechanism in the previous process can place the core mold 100 with the carbon cloth 200 attached onto the lower support plate 44. The lower support plate 44 moves backward and is positioned directly below the upper pressure plate 42. The upper pressure plate 42 presses down to hold the core mold, and the lower support plate 44 moves horizontally. Under the combined action of the upper pressure plate 42 and the lower support plate 44, the carbon cloth is wound onto the core mold, completing the tube winding operation.

[0068] A core mold limiting plate 441 is provided on the lower support plate 44 to limit the movement of the core mold towards the front side of the lower support plate 44. The core mold limiting plate 441 serves a positioning function when the core mold with attached carbon cloth is placed on the lower support plate 44 by the core mold gripping mechanism. The side wall of the core mold limiting plate 441 limits the movement of the core mold, and the carbon cloth attached to the core mold is located on the core mold limiting plate 441. When the upper pressure plate 42 presses down on the core mold and the lower support plate 44 moves relative to the upper pressure plate 42, the core mold limiting plate 441 also serves to restrict the movement of the core mold.

[0069] The rod conveyor 48 is used to receive and convey the mandrel with the carbon cloth wound up. The rod conveyor 48 includes multiple sets of powered roller assemblies 481, each consisting of rollers 4811 and a motor A4812 that drives the rollers 4811 to rotate. The fourth frame 41 has a guide roller 482 at the mandrel output end, driven by a motor B483. Under the action of the guide roller 482 and the powered roller assembly 481, the mandrel falling on the rollers 4811 is conveyed from the guide roller 482 side to the outside of the tube winding machine. Connecting with the conveyor line, the mandrel can be directly conveyed to the next process for curing.

[0070] The backing paper conveying device 49 includes a pressure plate 491 and an elastic cloth 492 disposed on the pressure plate 491. A backing paper collection box 410 is disposed on the fourth frame 41. Backing paper blown onto the elastic cloth 492 slides into the backing paper collection box 410.

[0071] The lower support plate 44 is connected to the L-shaped fixed base plate 411. A roller mounting side plate 412 is provided at the mounting roller 4811. The fixed base plate 11 and the roller mounting side plate 412 respectively support the central axis of the roller 4811. The motor mounting plate 413 is connected to the roller mounting side plate 412. The pressing plate 491 is located above the motor A4812 and is fixed to the roller mounting side plate 412. This design makes full use of space, and the tube winding machine has a compact structure and occupies little space.

[0072] The backing paper blowing mechanism 46 includes a blowing pipe 461 located in front of the upper pressure plate 42. The blowing pipe 461 has an array of blowing holes arranged to blow air onto the upper pressure plate 42. The blowing pipe 461 is connected to high-pressure gas, and the air blowing from the blowing holes blows the backing paper onto the elastic fabric 492. The lever mechanism 47 includes a pusher plate 471 and a pusher plate cylinder 472 that drives the pusher plate 471 to move up and down. During the process of the lower support plate 44 moving backward to the upper pressure plate 42, the pusher plate cylinder 472 drives the pusher plate 471 to rise, allowing the lower support plate 44 and its core mold to pass smoothly. When the winding operation is completed and the lower support plate 44 moves forward (towards the core mold gripping mechanism), the pusher plate cylinder 472 drives the pusher plate 471 to press down, thus moving the core mold on the lower support plate 44 onto the rod conveyor device 48 during the forward movement of the lower support plate 44.

[0073] When the carbon cloth with backing paper is bonded and pressed with the core mold, the backing paper and carbon cloth are separated only at the edges. When the core mold and the carbon cloth with backing paper are wound by the winding device 4, the upper pressure plate 42 presses down the core mold with the carbon cloth bonded on the lower support plate 44. The lower support plate 44 moves relative to the upper pressure plate 42, and the carbon cloth is wound on the core mold. The backing paper gradually separates from the carbon cloth and is adsorbed on the upper pressure plate 42. The backing paper blowing mechanism 46 blows the backing paper to the backing paper conveying device 49. The core mold with carbon cloth wound is pushed to the rod conveying device 48 by the lever mechanism 47, so that the backing paper and the core mold are separated and conveyed in an orderly manner after the tube is wound, thereby improving production efficiency.

[0074] This invention employs a core mold feeding device to deliver the core mold to the heat-pressing integrated device. Simultaneously, the low-melting-point adhesive on the core mold is melted. The carbon cloth supplied by the carbon cloth feeding device can directly adhere to the core mold, thus eliminating the need for applying adhesive to the core mold. During the bonding process of the carbon cloth and core mold, the backing paper of the carbon cloth separates from the carbon cloth adhered to the core mold. The backing paper separates from the core mold during the winding process of the carbon cloth and core mold, eliminating the need for tearing the backing paper. This invention optimizes the equipment for winding carbon cloth to the core mold, improving the efficiency of carbon fiber tube processing.

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.
