Description

Technical Field

[0001] This invention relates to the field of carbon fiber shoe manufacturing equipment, and more particularly to a coating vacuum equipment for manufacturing carbon fiber shoe bodies. Background Technology

[0002] Racing skates are professional sports shoes used in competitive skating sports such as ice skating, roller skating, and skiing. To improve athletes' speed and agility, these skates are made from carbon fiber, which is lightweight, high-strength, and durable, allowing athletes to achieve better performance and experience during competitions. This makes carbon fiber an ideal choice for manufacturing high-performance racing skates.

[0003] In the manufacturing process of carbon fiber shoe bodies, carbon fiber fabric is first cut into flat carbon fiber substrates. These substrates are then wrapped around a mold and pressed into a shoe body substrate using a hot press. Next, a fluid molding agent is applied to the substrate, and a film is used to cover the substrate. A vacuum process is then performed to ensure the film evenly covers and presses against the fluid molding agent surface. Finally, a heat curing process is conducted, allowing the fluid molding agent to penetrate the substrate, resulting in the finished shoe body. Vacuuming is a crucial step in carbon fiber shoe manufacturing. It removes air from the mold, allowing the carbon fiber fabric to better adhere to the mold surface, eliminating air bubbles, and enabling the fluid molding agent to penetrate the substrate. This ensures the finished shoe has uniform density and good quality. If vacuuming is inadequate or leaks occur during the manufacturing process, air bubbles will remain in the carbon fiber fabric and resin, or the carbon fiber fabric will not adhere tightly to the mold surface. This reduces the strength and durability of the product, affecting its quality, lifespan, and performance, and increasing the scrap rate. The reduced strength of carbon fiber shoe bodies increases the risk of breakage or damage during exercise or under heavy loads, posing a safety hazard to athletes. Currently, the vacuuming process in carbon fiber shoe body manufacturing typically involves manually covering the shoe body substrate (which has been coated with a fluid molding agent) from top to bottom with a thin film. The film's four edges are then secured to the worktable with a rectangular frame before a vacuum pump is activated to remove air from between the film and the substrate. However, when manually covering the substrate, wrinkles easily form on the film's edges, requiring significant time to repeatedly smooth them. Even with the rectangular frame securing the film, air leaks are still common. This makes incomplete vacuuming difficult, failing to achieve the required pressure and ensuring a proper vacuum within the film.

[0004] Therefore, existing vacuum pumping equipment needs further optimization and improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a coating and vacuuming device for manufacturing carbon fiber shoe bodies that eliminates the need for manual coating and ensures that air leakage is not likely to occur during the vacuuming process.

[0006] To achieve the above objectives, the present invention adopts the following solution: a vacuum coating device for manufacturing carbon fiber shoe bodies, comprising a frame housing, an equipment housing within the frame housing, an operating opening at the top of the frame housing for covering with a film, a lifting mechanism within the equipment housing, a platform at the top of the lifting mechanism for placing the carbon fiber shoe body, the platform being driven upward by the lifting mechanism to push the carbon fiber shoe body placed on the platform upward through the operating opening for film wrapping, and a hinged device at the top of the frame housing that can flip over to cover the top surface of the frame housing and place the film covering the operating opening. The four sides are pressed together to form a film-pressing frame. The center of the film-pressing frame has an opening that communicates with the operating port. The platform is equipped with an air extraction hole that can evacuate the space between the platform and the film after the platform is raised to push the carbon fiber shoe body upwards to wrap the film. The equipment housing is equipped with a vacuum pump that can be connected to the air extraction hole. The frame housing is equipped with a cover that can be fastened to the film-pressing frame. The cover is equipped with a heating device that can bake the film-covered shoe body on the platform. The frame housing is equipped with a control panel that can control the lifting mechanism, the vacuum pump and the heating device respectively.

[0007] As a further embodiment of the present invention, the upper cover is hinged to the film pressing frame, a locking hook is provided at the front end of the film pressing frame, and a buckle that can hook the locking hook is provided on the front side of the frame housing.

[0008] As a preferred embodiment of the present invention, a recessed operating cavity is provided on the top surface of the equipment accommodating chamber, the top of the operating cavity is connected to the operating port, the shelf is installed in the operating cavity in a height-adjustable manner, and the lifting mechanism includes a single-head cylinder installed on the bottom outer wall of the operating cavity, the output end of the single-head cylinder passes through the bottom wall of the operating cavity and is fixed together with the bottom surface of the shelf.

[0009] As a further embodiment of the present invention, the interior of the shelf is hollow, and the bottom of the shelf is connected to an air guide pipe that communicates with the inner cavity of the shelf. The bottom end of the air guide pipe is connected to a vacuum pump through a flexible tube, and the air extraction hole is connected to the inner cavity of the shelf.

[0010] As a preferred embodiment of the present invention, a partition is installed horizontally in the inner cavity of the shelf, and the partition is evenly and densely covered with ventilation holes.

[0011] As a preferred embodiment of the present invention, a positioning component is provided on the top surface of the storage platform to support and fix the carbon fiber shoe body placed thereon, and the bottom of the positioning component and the top surface of the storage platform are respectively provided with adjustment and fixing structures that can cooperate with each other to adjust the position of the positioning component.

[0012] As a preferred embodiment of the present invention, the adjusting and fixing structure includes "U"-shaped hook portions arranged sequentially at intervals along the top surface of the shelf. The back surface of the hook portion is inclined. A locking strip is provided at the bottom of the positioning member to engage with the inclined back surface of the hook portion. The surface of the locking strip that contacts the inclined back surface of the hook portion is also inclined. The front surface of the hook portion has a hook groove. A flip groove is provided at one end of the positioning member. A flip block is hinged in the flip groove. A fixing hook is provided at the bottom end of the flip block to engage with the hook groove. A spring is provided on the hinge shaft where the flip block and the flip groove are hinged to keep the fixing hook engaged in the hook groove.

[0013] As a further embodiment of the present invention, a film roller frame for inserting and fixing film rolls is provided on the front outer wall of the frame housing, and a cutting blade for cutting the film covering the operating port is provided at the front end of the pressing frame.

[0014] As a preferred embodiment of the present invention, the cutting blade includes a heating wire disposed along the bottom front end of the pressing frame.

[0016] In summary, the advantages of this invention compared to existing technologies are as follows: This invention, by first pressing the film with a pressing frame and then wrapping the carbon fiber shoe body, which has been coated with fluid forming agent, with the film wrapped from bottom to top, differs from the traditional method of manually wrapping the film from top to bottom. This achieves the effect of eliminating the need for complete manual wrapping and preventing wrinkles and air leaks at the edges of the wrapped film. It also ensures that no pressure leakage occurs during the vacuuming process, preventing air bubbles from remaining in the carbon fiber substrate. This effectively reduces the scrap rate of carbon fiber shoe products, guarantees the strength and durability of the carbon fiber shoe body, increases its lifespan and performance, and improves production efficiency.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Figures 1 to 11The illustrated vacuum coating equipment for manufacturing carbon fiber shoe bodies includes a frame housing 1. The frame housing 1 contains an equipment storage chamber 2. The top of the frame housing 1 has an operating opening 11 that can be covered with a thin film. A hinged door 15 is connected to the front of the frame housing 1, allowing the equipment storage chamber 2 to be exposed for maintenance. Inside the equipment storage chamber 2, a lifting mechanism 3 is provided. The top of the lifting mechanism 3 has a platform 4 on which the carbon fiber shoe body can be placed. The platform 4 is driven upwards by the lifting mechanism 3, pushing the carbon fiber shoe body placed on the platform 4 upwards through the operating opening 11 for film wrapping. A film-pressing frame 5 is hinged to the top of the frame housing 1, capable of flipping over to cover the top surface of the frame housing 1 and pressing the four sides of the film covering the operation port 11. The film-pressing frame 5 has an opening in the center that communicates with the operation port 11. The film-pressing frame 5 is actually a rectangular frame. A locking hook 55 is provided at the front end of the film-pressing frame 5, and a locking buckle 14 is provided on the front of the frame housing 1 to hook the locking hook 55. The platform 4 is provided with an air extraction hole 6, which can evacuate the space between the platform 4 and the film after the platform 4 is raised to push the carbon fiber shoe body upward to wrap the film. A vacuum pump 61 is provided in the equipment housing 2 that can be connected to the air extraction hole 6. The frame housing 1 has an upper cover 7 located above the film pressing frame 5, which can be fastened to the film pressing frame 5. The upper cover 7 is hinged to the hinge axis of the film pressing frame 5. The upper cover 7 has a heating device 8 inside, which can bake the film-coated shoe body on the platform 4. In this embodiment, the heating device 8 includes a ventilation hole 81 through the back of the upper cover 7. A fan 82 is provided inside the upper cover 7 at the ventilation hole 81. A heating tube 83 is provided between the inner wall of the back of the upper cover 7 and the fan 82. In this embodiment, the heating tube 83 is a finned heating tube. In addition, the upper cover 7 also has an observation window 71 for observing the state of the carbon fiber shoe body placed on the platform 4. The observation window 71 is made of heat-resistant glass. The door 15 of the frame housing 1 has a control panel 13 that can control the lifting mechanism 3, the vacuum pump 61 and the heating device 8 respectively. In this embodiment, the control panel 13 consists of multiple operation buttons, a pressure gauge, a timer and a PLC control module. In use: First, cover the operating port 11 with the film, flip the film pressing frame 5 down and lock the locking hook 55 with the buckle 14 to press the four sides of the film tightly onto the top surface of the frame box 1; through the control panel 13, let the lifting mechanism 3 lift the platform 4 from inside the operating port 11. The platform 4, along with the carbon fiber shoe body placed there, will just lift the film covering the operating port 11. The film will wrap around the top surface of the carbon fiber shoe body placed on the platform 4. At this time, start the vacuum pump 61 through the control panel 13 to extract the air between the film and the carbon fiber shoe body, so that the film completely wraps the carbon fiber shoe body.After vacuuming, flip and close the top cover 7, and start the heating device 8 through the control panel 13 to heat and cure the coated carbon fiber shoe body. It should be noted that in this embodiment, a rectangular adhesive strip 501 with the same outline as the bottom surface of the frame box 1 below the film pressing frame 5 is provided on the top surface. The rectangular adhesive strip 501 is used to make the bottom surface of the film pressing frame 5 and the top surface of the frame box 1 fit and seal as completely as possible. The film is laid on the rectangular adhesive strip 501. In this way, the film pressing frame 5 can completely press the film tightly without the problem of local air leakage.

[0032] Specifically, such as Figures 3 to 9 As shown, a recessed operating cavity 12 is provided on the top surface of the equipment accommodating chamber 2. The top of the operating cavity 12 is connected to the operating port 11. The platform 4 is installed in the operating cavity 12 in a height-adjustable manner. The lifting mechanism 3 includes a single-head cylinder 31 installed on the bottom outer wall of the operating cavity 12. The output end of the single-head cylinder 31 passes through the bottom wall of the operating cavity 12 and is fixed to the bottom surface of the platform 4. The interior of the platform 4 is hollow. The bottom of the platform 4 is connected to an air guide pipe 41 that communicates with the inner cavity of the platform 4. In this embodiment, the air guide pipe 41 consists of a fixed pipe 121 connected to the bottom of the operating chamber 12 and connected to the top of the operating chamber 12, and a telescopic pipe 122 inserted into the top of the fixed pipe 121 that can extend and retract. The top of the telescopic pipe 122 is connected to the platform 4 and communicates with the inner cavity of the platform 4. The telescopic pipe 122 moves up and down with the platform 4. The bottom end of the fixed pipe 121 is connected to the vacuum pump 61 through a flexible hose. The air extraction hole 6 communicates with the inner cavity of the platform 4. Because the membrane is easily broken, in order to ensure the uniformity of suction force during vacuuming, a partition 42 is installed horizontally in the inner cavity of the platform 4. The partition 42 is evenly and densely covered with vent holes 43. The suction force of the vacuum pump 61 will be dispersed through the densely covered vent holes 43, and will not be concentrated at the corresponding position of the air guide tube 41, which would cause excessive local suction pressure and tear the membrane at this position.

[0033] Among them, such as Figures 3 to 11As shown, during the entire vacuuming process, the carbon fiber shoe body is placed upside down on the surface of the platform 4 simultaneously with the internal mold. Therefore, to ensure the carbon fiber shoe body is stably fixed on the surface of the platform 4, and to prevent the film from being sucked in between the carbon fiber shoe body and the surface of the platform 4 during vacuuming, which could cause the film to break, a positioning member 9 is provided on the top surface of the platform 4 to support and fix the placed carbon fiber shoe body. In this embodiment, there are two positioning members 9, one in front and one behind, corresponding to the concave position of the upper and the position of the shoe collar of the carbon fiber shoe body, respectively. The two positioning members 9 perfectly fill the two gaps created by the inverted carbon fiber shoe body. Since different shoe sizes affect the position of the indentation on the shoe upper and the position of the shoe collar, the positioning component 9 in this invention is designed to be movable and adjustable. The bottom of the positioning component 9 and the top surface of the shelf 4 are respectively provided with adjusting and fixing structures 90 that cooperate with each other to adjust the position of the positioning component 9. The adjusting and fixing structure 90 includes hook portions 44 arranged in a "7" shape along the top surface of the shelf 4. The back surface of the hook portions 44 is inclined. At the bottom of the positioning component 9 is a locking strip 91 that can engage with the inclined back surface of the hook portions 44. The surface of the locking strip 91 that contacts the inclined back surface of the hook portions 44 is also inclined. The front of the hook portions 44 has a hook groove 45. A flipping groove 92 is provided at one end of the positioning component 9. A flipping block 93 is hinged within the flipping groove 92. The bottom end of component 3 is provided with a fixing hook 94 that can be hooked together with the hook groove 45. The hinge shaft of the flip block 93 and the flip groove 92 is provided with a coil spring 95 that can keep the fixing hook 94 hooked into the hook groove 45. When it is necessary to adjust the position of the positioning component 9 on the surface of the shelf 4, press the top of the flip block 93 to make the flip block 93 flip, and after the fixing hook 94 disengages from the hook groove 45, move the positioning component 9 backward so that the inclined surface on the clip 91 disengages from the inclined surface on the back of the hook part 44. Then the positioning component 9 can be removed, and the positioning component 9 is placed in the position to be adjusted. The clip 91 is pressed against the back of the hook part 44 again, and the flip block 93 is released. The flip block 93 is reset under the action of the coil spring 95 and hooks into the corresponding hook groove 45 again, completing the re-fixing of the positioning component 9 after adjustment. It should be noted that the shape of the positioning component 9 in this invention is determined by the shape of the gap between the carbon fiber shoe body and the surface of the shelf 4.

[0034] In addition, such as Figure 1 , Figures 3 to 10As shown, to facilitate covering the operating port 11 with film, a bearing seat 16 is provided on the front outer wall of the frame housing 1. A film roller frame 10 for inserting and fixing film rolls is horizontally hinged to the bearing seat 16. The film roller frame 10 includes a frame body 100 with one end horizontally hinged to the bearing seat 16. A roller shaft 101 with one side connection is installed on the frame body 100. A film roll 102 can be inserted and fixed on the roller shaft 101. When it is necessary to cover the operating port 11 with film, the frame body 100 is horizontally turned to the front side of the frame housing 1, and one end of the film roll 102 is pulled towards the back of the frame housing 1 and covered with the operating port 11. A cutting blade 50 is provided at the front end of the film pressing frame 5 to cut the film covered with the operating port 11. Specifically, the cutting blade 50 includes a heating wire 51 disposed along the bottom front end of the pressing frame 5. Rollers 52, located at the left and right ends of the heating wire 51, are respectively provided on the pressing frame 5 to support and fix the heating wire 51. An adjusting seat 53 is provided on one side of the pressing frame 5 to fix one end of the heating wire 51 and adjust its tension. A protective shell 54, with a central through-hole, is provided on the outer wall of the pressing frame 5 away from the adjusting seat 53. The end of the heating wire 51 away from the adjusting seat 53 passes through the protective shell 54 along one side of the pressing frame 5 and is electrically connected to the control panel 13 via a cable at the tail end of the protective shell 54. The two rollers 52 support the heating wire 51 to form a straight line. When one end of the film roll 102 covers the operating port 11, the pressing frame 5 is pressed down to press the film around the operating port 11. At this time, the heating wire 51 is activated to heat up, and the heating wire 51 will cut the film below using heat. When the heating wire 51 becomes loose after repeated use, it can be straightened again by adjusting the seat 53. The adjusting seat 53 consists of a guide block 56 fixed to the side of the pressing frame 5, and a slider 57 that can slide up and down and is locked on the guide block 56. The slider 57 has a winding wheel 58 on its side wall and a knob 59 pressed on one side of the winding wheel 58. One end of the heating wire 51 is wound around the winding wheel 58. A through hole is passed through the central axis of the winding wheel 58. The slider 57 corresponding to this through hole has a screw hole. The knob 59 has a screw that passes through the through hole of the shaft of the winding wheel 58 and is threaded into the screw hole of the corresponding through hole on the slider 57. By turning the knob 59, the screw connected to it is gradually screwed into the screw hole of the corresponding through hole on the slider 57, thereby squeezing the winding wheel 58 and preventing it from rotating. When it is necessary to straighten the heating wire 51 again, the knob 59 is loosened, the winding wheel 58 is rotated to tighten the heating wire 51, and then the knob 59 is tightened again. Additionally, another threaded hole is provided on the side wall of the guide block 56 adjacent to the winding reel 58. A bolt is threaded into the threaded hole, and the inner end of the bolt passes through the threaded hole and abuts against the guide block 56. When only the tightness of the heating wire 51 needs to be finely adjusted, the slider 57 can be moved along the guide block 56 to achieve this.

[0035] In addition, the present invention provides a material storage box 17 with a top opening on one side of the frame housing 1. On the back of the frame housing 1, there is a support rod 18 that can support the top cover 7 to prevent it from flipping back excessively after the film pressing frame 5 and the top cover 7 are flipped open, and a cooling fan 19 that can extract hot air from the equipment housing 2.

[0036] The foregoing has shown and described the basic principles and main features of the present invention, as well as its advantages. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
