[0013] Preferably, a placement frame is provided on the circular frame.

[0014] A manufacturing process of a carbon fiber roller comprises the following steps:

[0015] S1. First, place the carbon fiber roller to be processed into a placement frame, and discharge it from the bottom opening of the placement frame onto the placement plate. During the discharge process, make the frontmost carbon fiber roller contact with the outer wall of the first push plate.

[0016] S2. Start the motor. When the motor rotates, it drives the second gear to rotate. Since the second gear is meshed with the first gear through the chain, the first gear also rotates synchronously when the second gear rotates, thereby driving two grinding discs and one grinding roller to rotate simultaneously, so that the outer wall and both ends of the carbon fiber roller can be polished synchronously at the same time, further improving the grinding efficiency.

[0017] S3. By starting the cylinder, the cylinder pushes the push block forward during the extension and retraction process. As the push block moves forward, the second connecting shaft also moves forward and drives the swing plate to swing forward around the first connecting shaft. As the first connecting shaft swings forward, the first push plate connected thereto also moves. At this time, the upper end of the first push plate will remain flush with the upper end of the placement plate, so that the outer wall of the carbon fiber roller is in contact with the upper end of the first push plate.

[0018] S4. When the cylinder is reset, the push block moves backward, driving the swing plate to swing backward around the first connecting axis. At this time, the upper end of the first push plate pushes the carbon fiber roller to move upward and move upward along the outer wall of the baffle. When the height of the carbon fiber roller is consistent with the height of the baffle, the carbon fiber roller will roll from one side of the baffle to the other side, and with the help of the inclination angle of the inclined groove, slide onto the grinding disc and grinding roller for grinding.

[0019] S5. As the cylinder pushes again, the first pull plate, the second pull plate, and the third pull plate are driven to move synchronously, so that the arc-shaped baffle moves forward, pushes the carbon fiber roller at the rear, and fits tightly with the carbon fiber roller in the front.

[0020] S6. When the pushing block is pushed forward, the second inclined surface cooperates with the first inclined surface, thereby driving the adjustment plate to rotate around the second long rod. During the rotation of the adjustment plate, the other end of the adjustment plate pulls the first baffle to rotate around the first long rod, thereby facilitating the removal of the carbon fiber roller after grinding.

[0021] The positive effects of this application are:

[0022] The manufacturing process and preparation device of a carbon fiber roller provided by the embodiment of the present invention have the following advantages:

[0023] 1. A grinding roller is installed on the lower rotating shaft, which is mainly used to grind the surface of the carbon fiber roller; and the two upper rotating shafts are respectively provided with grinding discs, which are responsible for grinding the ends of the carbon fiber roller. In this way, the carbon fiber roller can be double-grinded from the surface and the end during the grinding process, which greatly improves the grinding effect and efficiency;

[0024] In order to drive the grinding disc and grinding roller to rotate synchronously, a motor is installed on the bottom plate, and a second gear is sleeved on its output shaft. Through the connection of the chain, the second gear can mesh with the four first gears at the same time, thereby realizing the synchronous drive of the grinding roller and the grinding disc. This design not only simplifies the transmission structure, but also improves the transmission efficiency, ensuring the stability and reliability of the grinding process.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0033] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0034] like Figure 1-6As shown, the present invention is a manufacturing device for a carbon fiber roller, comprising a bottom plate 1 and a placement plate 13, wherein the bottom plate 1 and the placement plate 13 are connected via a first support rod 11; an inclined groove 15 is provided on the placement plate 13; two first support rods 2 are provided on the bottom plate 1, and rotating shafts 21 distributed up and down are respectively provided on the first support rods 2, and the rotating shafts 21 are sleeved with first gears 22 near the ends, and the rotating shafts 21 located at the bottom are sleeved with grinding rollers 28, and the two rotating shafts 21 located at the top are both provided with grinding discs 29; a motor 23 is installed on the bottom plate 1, and a second gear 24 is sleeved on the output shaft of the motor 23, and a chain 25 is meshed between the second gear 24 and the first gear 22; a support plate 26 is provided on the first support rod 2, and a first long rod 261 is provided between the two support plates 26, and a first baffle 27 is provided on the first long rod 261;

[0035] A grinding roller 28 is installed on the lower rotating shaft 21, which is mainly used to grind the surface of the carbon fiber roller; and the two upper rotating shafts 21 are respectively provided with grinding discs 29, which are responsible for grinding the ends of the carbon fiber roller, so that the carbon fiber roller can be double-grinded from the surface and the end during the grinding process, which greatly improves the grinding effect and efficiency;

[0036] In order to drive the grinding disc 29 and the grinding roller 28 to rotate synchronously, a motor 23 is installed on the bottom plate 1, and a second gear 24 is sleeved on the output shaft thereof. The second gear 24 can mesh with the four first gears 22 at the same time through the connection of the chain 25, thereby realizing the synchronous driving of the grinding roller 28 and the grinding disc 29. This design not only simplifies the transmission structure, but also improves the transmission efficiency, and ensures the stability and reliability of the grinding process.

[0037] The first baffle 27 is arranged at an angle, which not only supports the functionality of the carbon fiber roller, but also takes into account the convenience of operation and the stability of the structure. The inclined first baffle 27 can effectively disperse the lateral pressure that may be generated by the carbon fiber roller during the processing, and prevent it from rolling or deflecting due to uneven force, thereby ensuring the precise position of the carbon fiber roller during the processing;

[0038] Two third support rods 3 are provided on the bottom plate 1, and a second baffle 31 is commonly provided on the two third support rods 3. The second baffle 31 is inclined and is located between the grinding roller 28 and the inclined groove 15. The first baffle 27 and the second baffle 31 jointly form a V-shape to form a stable support area, which provides a safe and stable processing environment for the carbon fiber roller. This facilitates the support of the carbon fiber roller to ensure the stability of the carbon fiber roller during the processing.

[0039] The first support rod 2 is rotatably provided with a second long rod 4 , and the second long rod 4 is sleeved with an adjustment plate 41 . One end of the adjustment plate 41 is provided with a first inclined surface 42 , and the other end of the adjustment plate 41 is hinged to the outer wall of the first baffle 27 .

[0040] Preferably, a cylinder 5 is installed on the base plate 1 through a second support rod 12, a push block 51 is provided at the output end of the cylinder 5, two push grooves 14 and a first connecting shaft 52 and a baffle 57 are provided on the placement plate 13, swing plates 53 are rotatably provided at both ends of the first connecting shaft 52, shaft grooves 54 are provided on the swing plates 53, second connecting shafts 55 are provided in the shaft grooves 54, and opposite ends of the second connecting shaft 55 are commonly connected to the push block 51; a first push plate 56 is provided on the swing plate 53, and one end of the first push plate 56 extends out of the push groove 14.

[0041] Preferably, the first push plate 56 has an L-shaped structure, and the longer end of the first push plate 56 extends out of the push groove 14, and the end face is an inclined slope. When the first push plate 56 rotates around the first connecting shaft 52, the longer end of the first push plate 56 moves downward, so that the end face of the longer end of the first push plate 56 is flush with the upper end face of the placement plate 13, and they are on the same plane; the end of the first push plate 56 extending out of the push groove 14 is provided with a rubber pad for protecting the surface of the carbon fiber roller and preventing the surface of the carbon fiber roller from being scratched; the baffle plate 57 has a conical structure, and the outer inclined surface of the baffle plate 57 contacts with the extended end of the first push plate 56, so that the first push plate 56 can push the carbon fiber roller through the baffle plate 57.

[0042] Preferably, the push block 51 is provided with a second push plate 6, and the second push plate 6 is provided with a second inclined surface 61, and the second inclined surface 61 cooperates with the first inclined surface 42; when the push block 51 is pushed forward, the second inclined surface 61 cooperates with the first inclined surface 42, and due to the design of the inclined surface, the contact between the two will generate an upward component force, and this component force will cause the adjustment plate 41 to rotate around the second long rod 4;

[0043] As the adjustment plate 41 rotates, its other end will be displaced accordingly. The first baffle 27 is also able to rotate around a first long rod 261 as a fulcrum. Therefore, when the adjustment plate 41 rotates and pulls the first baffle 27, the first baffle 27 will rotate around the first long rod 261, thereby changing its position, so that the carbon fiber roller after grinding can be taken out more easily and smoothly. This not only improves the degree of automation of the operation, but also greatly simplifies the process of taking out the carbon fiber roller and improves work efficiency.

[0044] Preferably, the side baffle 8 is provided with a circular frame 7, and the two circular frames 7 are provided with a first pull plate 73, and the two ends of the first pull plate 73 extend out of the circular frame 7 and are provided with a second pull plate 74; the middle part of the first pull plate 73 is provided with an arc baffle 76, and the arc baffle 76 cooperates with the outer wall of the carbon fiber roller and pushes the carbon fiber roller to move forward; the second pull plate 74 is provided with a third pull plate 75, and the opposite end of the third pull plate 75 is connected to the push block 51; a spring 71 is provided in the circular frame 7, and the spring 71 is provided in the circular frame 7. The spring 71 is provided to facilitate the reset of the first pull plate 73, and the guide rod 72 is provided to limit the position of the first pull plate 73 to prevent the first pull plate 73 from deflecting during the movement; one end of the spring 71 is connected to the first pull plate 73, and the other end of the spring 71 is connected to the inner wall of the circular frame 7. A guide rod 72 is provided in the spring 71, and one end of the guide rod 72 passes through the first pull plate 73 and extends out of the circular frame 7, and the other end of the guide rod 72 is connected to the inner wall of the circular frame 7;

[0045] The first pull plate 73, the second pull plate 74, and the third pull plate 75 cooperate to drive the arc-shaped baffle plate 76 to move forward, thereby ensuring a close fit of the carbon fiber roller, thereby facilitating subsequent grinding.

[0046] Preferably, the circular frame 7 is provided with a placement frame 9 for placing the untreated carbon fiber roll; the placement plate 13 is provided with two side baffles 8, and the side baffles 8 are used to limit the positions of the two ends of the carbon fiber roll.

[0047] A manufacturing process of a carbon fiber roller comprises the following steps:

[0048] S1. First, place the carbon fiber roller to be processed into the placement frame 9, and discharge it from the bottom opening of the placement frame 9 onto the placement plate 13. During the discharge process, make the frontmost carbon fiber roller contact with the outer wall of the first push plate 56.

[0049] S2. Start the motor 23. During the rotation of the motor 23, the second gear 24 is driven to rotate. Since the second gear 24 is meshed with the first gear 22 through the chain 25, the first gear 22 is also rotated synchronously while the second gear 24 is rotating, thereby synchronously driving the two grinding discs 29 and a grinding roller 28 to rotate simultaneously, so that the outer wall and both ends of the carbon fiber roller can be synchronously polished at the same time, further improving the grinding efficiency.

[0050] S3. By starting the cylinder 5, the cylinder 5 pushes the push block 51 to move forward during the extension and retraction process. As the push block 51 moves forward, the second connecting shaft 55 also moves forward and drives the swing plate 53 to swing forward around the first connecting shaft 52. As the first connecting shaft 52 swings forward, the first push plate 56 connected thereto also moves. At this time, the upper end of the first push plate 56 will remain flush with the upper end of the placement plate 13, so that the outer wall of the carbon fiber roller is in contact with the upper end of the first push plate 56.

[0051] S4. When the cylinder 5 is reset, the push block 51 moves backward, driving the swing plate 53 to swing backward around the first connecting shaft 52. At this time, the upper end of the first push plate 56 pushes the carbon fiber roller to move upward and moves upward along the outer wall of the baffle 57. When the height of the carbon fiber roller is consistent with the height of the baffle 57, the carbon fiber roller will roll from one side of the baffle 57 to the other side, and with the help of the inclination angle of the inclined groove 15, slide onto the grinding disc 29 and the grinding roller 28 for grinding.

[0052] S5. As the cylinder 5 pushes again, the first pull plate 73, the second pull plate 74, and the third pull plate 75 are driven to move synchronously, so that the arc baffle 76 moves forward, pushes the rear carbon fiber roller, and fits tightly with the front carbon fiber roller.

[0053] S6. When the pushing block 51 is pushed forward, the second inclined surface 61 cooperates with the first inclined surface 42, thereby driving the adjustment plate 41 to rotate around the second long rod 4. During the rotation of the adjustment plate 41, the other end of the adjustment plate 41 pulls the first baffle 27 to rotate around the first long rod 261, thereby facilitating the removal of the carbon fiber roller after grinding.

[0054] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
