Description

Technical Field

[0001] This invention belongs to the field of winding machine technology, and particularly relates to a prepreg tape winding machine. Background Technology

[0002] A winding machine is an automated device that winds continuous materials (such as metal strips, plastic films, paper, etc.) into regular rolls. It is widely used at the end of material processing production lines.

[0003] Existing carbon fiber prepreg tapes typically require a winding machine for winding after slitting. Patent CN217350047U discloses a fully automatic prepreg tape winding device that directly winds the prepreg tape onto a winding shaft. However, because the prepreg tape contains uncured resin matrix, the layers are in close contact after winding. During long-term storage, the resin's viscosity can cause adhesion, leading to tearing of the prepreg tape during subsequent unwinding and disrupting the internal fiber arrangement.

[0004] Therefore, it is necessary to improve the existing prepreg tape winding machine. Summary of the Invention

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the winding machine and are only for the purpose of describing the present invention and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] like Figure 1-4As shown, a prepreg tape slitting and winding machine includes a machine body 1, on which a winding mechanism 2 for winding tape 4 and an unwinding mechanism 3 for unwinding release paper tape 5 are provided. The winding mechanism 2 includes a first tensioning roller 22, a winding roller 21, and a plurality of first guide rollers 23 rotatably mounted on the machine body 1. The tape 4 passes sequentially along a first path through the first tensioning roller 22 and each of the first guide rollers 23, and is finally wound onto the winding roller 21. The unwinding mechanism 3 includes a second tensioning roller 34, an unwinding roller 31, and a plurality of second guide rollers 37 rotatably mounted on the machine body 1. After the release of the release roller 31, the release paper strip 5 passes through the second tension roller 34 and each of the second guide rollers 37 in sequence along the second path, and is finally wound onto the take-up roller 21. The take-up roller 21 pulls the release paper strip 5 and the strip 4 to be wound synchronously, and the release paper strip 5 is located on the side of the strip 4 closer to the axis of the take-up roller 21. Two magnetic powder brakes 222 are provided on the machine body 1. The movable ends of the two magnetic powder brakes 222 are fixedly connected to the swing rods 221. The first tension roller 22 and the second tension roller 34 are respectively rotatably mounted on the two swing rods 221.

[0021] The aforementioned winding machine is suitable for winding slit carbon fiber prepreg tape. In the winding mechanism 2, the slit prepreg tape 4 is conveyed along the first path to the winding roller 21 for winding under the guidance of each first guide wheel 23. During the winding process, the tension of the tape 4 during winding is controlled by the first tension wheel 22. At the same time, the rolled release paper tape 5 is installed on the unwinding roller 31. The unwound release paper tape 5 is conveyed along the second path to the winding roller 21 under the guidance of each second guide wheel 37. During the winding process, the tension of the release paper tape 5 during winding is controlled by the second tension wheel 34. After the release paper tape 5 and the tape 4 are bonded together, they are synchronously wound onto the winding roller 21. The surface of the release paper tape 5 is provided with a release layer, which can prevent the tape from being rolled into the windmill. The prepreg tape 4 and the release paper tape 5 adhere to each other. By setting the release paper tape 5 between the layers of the wound tape 4, the adjacent layers of tape 4 can be separated, thereby effectively preventing the prepreg tape between adjacent layers from sticking together during long-term storage. This makes it easier to unwind the prepreg tape during subsequent use and improves the practicality of the prepreg tape winding machine. The machine body 1 is equipped with two drive motors, which are used to drive the winding roller 21 and the unwind roller 31 to rotate respectively. At the same time, a cylinder is also provided to push the drive motor to move back and forth along the axial direction of the winding roller 21 and the unwind roller 31. This allows the winding roller 21 and the unwind roller 31 to move back and forth along their own axial direction while rotating, thereby realizing the orderly unwinding of the release paper tape 5 and the orderly winding of the release paper tape 5 and the tape 4, improving the winding effect of the winding machine.

[0022] Further improvements include, for example Figure 7 , 8As shown in Figure 13, the unwinding mechanism 3 also includes an embossing assembly 32 disposed on the machine body 1. The embossing assembly 32 is disposed adjacent to the unwinding roller 31 along the second path. The embossing assembly 32 includes an embossing roller 322 and a pressing roller 321 both rotatably disposed on the machine body 1. The pressing roller 321 is a rubber roller and abuts against the embossing roller 322 radially. A first ridge 323 and a second ridge 324 are disposed on the outer circumferential surface of the embossing roller 322. The first ridge 323 is disposed in segments around the axis of the embossing roller 322 on the outer circumference of the embossing roller 322. Multiple first ridges 323 are disposed and distributed at intervals along the axial direction of the embossing roller 322. The first ridge 323 presses the release paper strip 5 to form a first stripe 51 extending along its length direction on the release paper strip 5. The second ridge 324 extends along the axial direction of the embossing roller 322. The second ridge 324 presses the release paper strip 5 to form a second stripe 52 extending along its width direction on the release paper strip 5.

[0023] After the release paper tape 5 is placed between the layers of the prepreg tape, the adhesion between the release paper tape 5 and the prepreg tape is reduced due to the release layer on the surface of the release paper tape 5. During the long-term storage of the rolled prepreg tape, the tape 4 and the release paper tape 5 are prone to relative sliding under the action of gravity, which leads to misalignment between the two. This can easily cause the rolled prepreg tape to deform and loosen, resulting in entanglement. Furthermore, after the misalignment between the tape 4 and the release paper tape 5, the tape 4 is prone to contact with each other, which can cause the layers of tape 4 to stick together again, affecting subsequent unfolding and use.

[0024] In the aforementioned winding machine, a separate motor is installed on the machine body 1 to drive the embossing roller 322 to rotate independently. The pressing roller 31 is in contact with the embossing roller 322, so that under the action of friction, the embossing roller 322 drives the pressing roller 31 to rotate synchronously. The release paper tape 5 passes between the embossing roller 322 and the pressing roller 31, and the pressing roller 31 presses the release paper tape onto the embossing roller 322, so that the embossing roller 322 can press out the first stripe 51 and the second stripe 52 on the release paper tape 5. The setting of the first stripe 51 and the second stripe 52 can firstly increase the friction between the release paper tape 5 and the strip 4, prevent relative sliding between the strip 4 and the release paper tape 5 after winding, and ensure that the release paper tape 5 is aligned with the strip 4. The isolation effect of the strips 4 between adjacent layers can also maintain the orderly arrangement of the strips 4 during long-term storage, preventing the strips 4 from tangling together and facilitating the unwinding and rewinding of the prepreg tape during use. Since the first convex strip 323 is segmented, a first stripe 51 with discontinuous breaks can be pressed into the release paper strip 5. Since the release paper strip 5 deforms at the first stripe 51, the connection strength is lower. Compared with the continuous first stripe 51, the release paper strip 5 at the break can still maintain its own stable structure. This can improve the overall firmness of the release paper strip 5 and reduce the probability of the release paper strip 5 breaking and deforming, so as to ensure the isolation effect of the release paper strip 5.

[0025] Further improvements include, for example Figure 9 and 10 As shown, the unwinding mechanism 3 also includes a punching assembly 33 mounted on the machine body 1. A sensor 3312 fixedly connected to the machine body 1 is disposed between the punching assembly 33 and the embossing assembly 32. The punching assembly 33 is disposed adjacent to the embossing assembly 32 along the second path. Multiple through holes 53 are punched into the release paper tape 5 by the punching assembly 33. The through holes 53 are evenly distributed along the length direction of the release paper tape 5. The punching assembly 33 includes a collection box 331 fixedly connected to the machine body 1. The bottom surface of the collection box 331 is open, and a bottom cover 332 is provided at the open surface. The top wall of the collection box 331 has a vertical cutting hole 334 that penetrates the wall thickness. A lifting punch 3310 is coaxially arranged above the cutting hole 334. Two guide posts 337 are vertically fixedly connected to the top surface of the collection box 331. A bracket 335 and a lifting seat 3311 are arranged between the two guide posts 337. The bracket 335 can be detachably connected to the top of the two guide posts 337. The lifting seat 3311 is slidably engaged with the two guide posts 337. The punch 3310 is fixedly connected to the lifting seat 3311. A power component that is driven by the lifting seat 3311 is arranged on the bracket 335.

[0026] In the aforementioned winding machine, the power components include an electromagnet 336 fixed on the bracket 335 and a permanent magnet 338 fixed on the lifting seat 3311. A spring 339 is fitted onto the guide post 337, with its two ends connected to the lifting seat 3311 and the collection box 331, respectively. The sensor 3312 is a non-contact displacement sensor that can effectively detect the positions of the first stripe 51 and the second stripe 52 on the release paper tape 5, using the second stripe 52 as the punching mark for the through hole 53. When the sensor 3312 detects that the second stripe 52 has moved to the cutting hole 334, the electromagnet 336 is energized, pushing the permanent magnet 338 downwards. The lifting seat 3311 descends, and the punching knife 3310, being a columnar structure, punches through holes 53 in the release paper tape 5 through the punching knife 3310 and the cutting hole 334. The cut-off debris from the release paper tape 5 enters the collection box 331 for collection, preventing the debris from scattering and adhering to the tape 4. After punching, the electromagnet 336 is de-energized, and the punching knife 3310 is reset under the elastic force of the spring 339, thus completing the punching of the through hole 53. The bottom cover 332 is fixed to the collection box 331 by a hand-tightened screw, allowing the bottom plate 332 to be opened and closed, thus facilitating the cleaning of the debris collected inside the collection box 331.

[0027] Through the above steps, through holes 53 are punched into the release paper tape 5. After the tape 4 is wound up, the resin on the prepreg tape can pass through the through holes 53 and form small anchor points between the prepreg tapes of adjacent layers. This can further improve the stability of the connection between the tapes 4 of adjacent layers after winding, as well as the stability of the release paper tape 5. It prevents relative sliding between the rolled tapes 4, and prevents the guide tapes from tangling and sticking together. This improves the winding effect of the winding machine on the prepreg tape and the long-term storage effect of the prepreg tape roll. In addition, the second stripe 52 formed on the release paper tape 5 can also serve as a punching position mark. At the same time, the first stripe 51 extending along the length direction of the release paper tape 5 can also serve as a position mark. By detecting the position of the first stripe 51, it can be detected whether the release paper tape 5 has deviated before entering the punching assembly 33, thereby improving the positional accuracy of the through holes 53 on the release paper tape 5.

[0028] Further improvements include, for example Figure 11 and 12As shown, the machine body 1 is also provided with a cleaning component 35, which is arranged behind the punching component 33 along the second path. The cleaning component 35 includes a cleaning box 351 fixedly connected to the machine body 1 via a mounting base 352. The top surface of the cleaning box 351 is open, and a top cover 358 is provided at the open. The cleaning box 351 is provided with second guide wheels 37 rotatably connected to the mounting base 352 at both the front and rear sides along the second path. The cleaning box 351 is provided with slots 356 on both sides adjacent to the second guide wheels 37 for the isolation paper tape 5 to pass through. Two roller brushes 357 are rotatably arranged inside the cleaning box 351. The two roller brushes 357 are located on both sides of the isolation paper bag and are driven by a hub motor 355 to rotate in opposite directions. The isolation box is also connected to an air extraction pipe 353.

[0029] Because dust or impurities easily adhere to the release paper tape 5, and debris is easily generated after being processed by the embossing component 32 and the punching component 33, these impurities adhere to the tape 4, which redundantly affects the quality of the tape 4. Therefore, a cleaning component 35 is set up to clean the release paper tape 5. Specifically, the machine body 1 is equipped with an air pump connected to the air extraction pipe 353, the side of the hub motor 355 is provided with an axially extending insertion groove 354, and the inner wall of the roller brush 357 is provided with an axially extending insertion strip 359. The two can be inserted and matched with each other, thereby facilitating the disassembly and replacement of the roller brush 357.

[0030] When the above-mentioned wrapping machine is in use, under the guidance of the two second guide wheels 37, the release paper tape 5 can pass through the inside of the cleaning box 351 from the slot 356. During this process, the hub motor 355 drives the two roller brushes 357 to rotate in opposite directions, so that the two roller brushes 357 clean both sides of the release paper tape 5 respectively. At the same time, the two roller brushes 357 rotate synchronously in opposite directions, which can also cancel out the force generated on the release paper tape 5, prevent the release paper tape 5 from moving along the second path, and facilitate the control of the pre-tension of the release paper tape 5. The debris and impurities under cleaning are sucked out by the air extraction pipe 353 in time, which can prevent the release paper tape 5 from being contaminated again. By cleaning the release paper tape 5, the probability of the tape 4 being contaminated can be reduced, and the quality of the prepreg tape wound by the wrapping machine can be improved.

[0031] Further improvements include, for example Figure 4-6As shown, a second positioning wheel 36 is arranged adjacent to the front of the take-up roller 21 along the second path. A limiting groove 361 is provided circumferentially on the outer periphery of the second positioning wheel 36. The width of the limiting groove 361 gradually decreases from the groove opening 356 to the bottom of the groove. A protrusion 362 matching the through hole 53 is provided at the bottom of the limiting groove 361. A first positioning wheel 24 is arranged between the take-up roller 21 and the second positioning wheel 36. Both the first path and the second path pass through the first positioning wheel 24. Positioning sleeves 242 are fitted on the outer periphery of both ends of the first positioning wheel 24, and a positioning groove 241 for accommodating the strip 4 is formed between the two positioning sleeves 242.

[0032] In the aforementioned winding machine, the release paper tape 5, after embossing, punching, and cleaning, is fed to the second positioning roller 36, while the slit prepreg tape is fed to the first positioning roller 24. Afterward, the release paper tape 5 and the tape 4 are bonded together and wound onto the take-up tube 21 to form a prepreg roll. During winding, the prepreg tape is finally positioned by the positioning groove 241, and the release paper tape 5 is initially positioned by the limiting groove 361. Then, each through hole 53 on the release paper tape 5 engages with the semi-circular protrusion 362, achieving final positioning of the release paper tape 5. Since both the first positioning roller 24 and the second positioning roller 36 are located close to the take-up tube 31, the release paper tape 5 adheres to the outer circumferential surface of the first positioning roller 24, achieving mutual bonding between the release paper tape 5 and the tape 4. The bonded sides are then wound onto the take-up roller 21, which can improve the release paper tape's elasticity. The positioning accuracy between the paper tape 5 and the tape 4 improves the quality of the prepreg roll after winding by the wrapping machine and facilitates long-term storage of the prepreg roll. The positioning sleeve 242 can be fixedly connected to the first positioning wheel 24 by tape. By changing the thickness of the positioning sleeve 242 and adjusting the distance between the two positioning sleeves 242, the depth and width of the positioning groove 241 can be changed to adapt to prepreg tapes of different sizes. At the same time, after the tape 4 is sunk into the positioning groove 241, the outer circumference of the first positioning wheel 24 can be kept relatively flat. When the release paper tape 5 is attached to the first positioning wheel 24, the flat surface can support the release paper tape 5, prevent the release paper tape 5 from folding and deforming, and thus change the width of the release paper tape 5. This improves the positioning accuracy of the release paper tape 5 after it is attached to the tape 4 and enhances the isolation effect of the release paper tape 5.

[0033] In this winding machine, during the processing of the release paper tape 5, first stripes 51 and second stripes 52 are pressed onto it. The first stripes 51 and second stripes 52 increase the friction between the release paper tape 5 and the tape 4, preventing relative displacement between them. This improves the quality of the prepreg roll after winding and the stability of its storage. Simultaneously, the first stripes 51 and second stripes 52 serve a positioning function during punching. The through holes 53 on the release paper tape 5 allow a small amount of resin to pass through, creating anchor points between adjacent layers of tape 4, further preventing relative displacement and improving the quality of the prepreg roll after winding and the stability of its storage. Simultaneously, by controlling the diameter of the through hole 53, the anchor point can have appropriate connection strength, which can prevent misalignment between prepreg layers without affecting subsequent unwinding. The through hole 53 can also cooperate with the protrusion 362 before the release paper tape 5 is bonded to the strip 4 to position the release paper tape 5. At the same time, the strip 4 is also positioned by the positioning groove 241, thereby effectively controlling the relative position between the release paper tape 5 and the strip 4, so that the release paper tape 5 can effectively cover the strip 4, improve the isolation effect between the layers of the strip 4, and thus improve the winding effect of the prepreg tape by the winding machine. Through the close cooperation between each process, the quality of the prepreg tape wound by the winding machine is ultimately improved.
