Description

Technical Field

[0001] The present invention belongs to the technical field of double-roller rolling, and specifically relates to a carbon fiber sheet and its double-roller automatic rolling machine. Background Art

[0002] Due to its high strength, light weight and excellent corrosion resistance, carbon fiber sheets are widely used in fields such as aerospace, automotive manufacturing, and sports equipment. During the production process, carbon fiber sheets need to undergo a rolling process to ensure their thickness uniformity and surface flatness. Traditional carbon fiber sheet rolling machines usually adopt a double-roller structure, and the sheet is rolled by the relative movement of two rollers.

[0003] For example, the utility model with the publication number CN208303482U discloses a double-roller rolling device for waste automobiles, including a bottom plate, a gantry, a conveyor belt, a data processing module, a data analysis module, and a data transmission module. The rolling device of the present invention is provided with rolling rollers placed up and down. After the car body enters following the conveyor belt and is rolled by the upper and lower rollers, the car body is flattened and then input following the conveyor belt. An acceleration sensor, a positioning transceiver device, and a data transceiver device are provided on the driving roller. Cooperating with the data processing module, the data analysis module, and the data transmission module, the rolling operation parameters of the car body are monitored in real time, and the data is transmitted back to the driving motor, the conveyor motor, and the hydraulic oil pump in a timely manner to control the driving motor, the conveyor motor, and the hydraulic oil pump, strictly controlling the rolling process and the rolling quality. This not only greatly reduces manual operation, saves labor costs, and reduces the uncontrollability of human factors, but also realizes the automation and intelligence of the rolling operation process, improving the overall rolling quality.

[0004] There is a significant problem with existing double-roller automatic rolling machines after rolling. The winding process of the sheet requires manual intervention. When the rolling process is completed, the sheet often stays between the rollers or accumulates at the equipment outlet. The operator needs to manually remove the sheet from the equipment and wind it up. This not only increases the labor intensity but also may cause the sheet to be contaminated or damaged during the winding process, affecting the product quality. In addition, the efficiency of manual winding is low and cannot meet the requirements of large-scale production. Especially during continuous production, frequent manual intervention will cause the production line to stop, reducing the overall production efficiency.

[0005] Therefore, a carbon fiber sheet and its double-roller automatic rolling machine are proposed to solve the problems raised in the background art. Summary of the Invention

[0006] To solve the problems raised in the above background art, the present invention provides a carbon fiber sheet and its double-roller automatic rolling machine.

[0009] Preferably, the winding roller is located between the two support plates, and a rotating motor fixedly connected to one of the support plates is fixedly provided at one end of the winding roller.

[0010] Preferably, a support block is fixedly provided at the bottom of the arc plate, the support block is fixedly connected to the bottom of the mounting frame, a central groove is opened at the center of the arc plate, a placing groove is opened inside the central groove, and the arc plate is in a quarter-circular shape and is located on the outer wall of the winding roller.

[0012] Preferably, the bottom of the cross bar is fixedly connected to the extension plate. One side of the connecting circular plate away from the mounting plate is fixedly provided with a connecting rod, and a moving block that is slidably clamped with the placement groove is fixedly provided at the center of the mounting plate.

[0013] Preferably, the carbon fiber sheet body passes between the arc plate and the winding roller. A cutting assembly for cutting the carbon fiber sheet body is provided at the top of the rectangular plate.

[0014] Preferably, the driving assembly includes a connecting rod fixedly provided on the connecting rod, a crank clamped on the connecting rod, a fixed arc plate fixedly provided on one side of the mounting frame and rotatably connected to the end of the connecting rod away from the connecting rod, a protruding arc plate fixedly provided on the side of the fixed arc plate away from the mounting frame, and an adjusting motor fixedly provided on the protruding arc plate. The adjusting motor is fixedly connected to the side of the crank away from the connecting rod.

[0015] Preferably, the fixed arc plate is in a quarter - circle shape, and an arc - shaped groove is formed on the fixed arc plate. The connecting rod slides along the arc - shaped groove.

[0016] Preferably, the cutting assembly includes a cutting knife located at the top of the mounting plate, vertical plates slidably arranged on the top of the cross bar and fixedly connected to both ends of the cutting knife, and a second electric push rod fixedly provided on the rectangular plate for pushing the vertical plates to move.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation of structures such as the winding roller, the arc plate, and the fixing component, the present invention facilitates the automatic winding of the carbon fiber sheet after rolling. The carbon fiber sheet body passes through the first pressing roller and the second pressing roller of the rolling mechanism. The distance between the two pressing rollers is adjusted by the electric cylinder to control the rolling thickness. Then, the motor is controlled to drive the pressing rollers to rotate to complete the rolling and transmission of the carbon fiber sheet. For convenient storage, the winding mechanism is used to automatically wind the rolled carbon fiber sheet. The arc plate guides the carbon fiber sheet to the fixing component. After being fixed, the driving component makes it closely adhere to the winding roller along the trajectory of the arc plate. The rotating motor is started to drive the winding roller to rotate, and it is released when the carbon fiber sheet reaches the winding position, realizing automatic winding. This solves the problem that the existing double - drum automatic rolling machine for carbon fiber sheets is not convenient for automatic winding after rolling and requires manual intervention, which not only increases the labor intensity and production cost, but also affects the production efficiency and product quality.

[0018] Through the cooperation of structures such as clamping plates, cross bars, and first electric push rods, the present invention facilitates the rapid clamping and fixing of the rolled carbon fiber sheets. The rolled carbon fiber sheet body vertically drops to one side of the arc-shaped plate under the action of gravity. The first electric push rod is used to push the clamping plate, causing it to rotate hingedly around the cross bar. The top of the clamping plate approaches the mounting plate, thereby clamping the carbon fiber sheet body. After fixation, the driving component drives the moving block to slide along the insertion groove, pushing the carbon fiber sheet to move along the surface of the winding roller for convenient winding. During winding, the first electric push rod resets, causing the clamping plate to return to the vertical state to avoid interfering with the winding process.

[0019] Through the cooperation of structures such as cranks, connecting rods, and cutting components, the present invention facilitates the traction and cutting of the rolled carbon fiber sheets. The driving component drives the crank to rotate through the adjusting motor, causing the connecting rod to be hinged to the fixed arc plate and driving the connecting rod to swing along the arc-shaped groove, thereby pushing the mounting plate and the moving block to slide along the central groove of the arc-shaped plate to achieve the traction of the carbon fiber sheet body, making it close to the winding roller. After winding is completed, to avoid the limitation of the winding roller capacity, the cutting component is used to quickly cut the carbon fiber sheet. During cutting, the carbon fiber sheet is first clamped, and then the second electric push rod pushes the vertical plate to slide along the cross bar, driving the cutting knife to approach the carbon fiber sheet to complete the cutting.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments 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 are within the scope of protection of the present invention.

[0023] like Figures 1 to 10 As shown, the present invention provides a carbon fiber sheet, including a carbon fiber sheet body 2. The carbon fiber sheet body 2 is a thin sheet-like composite material made of carbon fiber material, and has excellent properties such as high strength, light weight, corrosion resistance, and high temperature resistance. It is usually composed of carbon fiber tows or fabrics and a resin matrix such as epoxy resin through a specific process such as hot pressing molding, impregnation curing, etc.

[0024] A double-roller automatic rolling machine includes a rolling mechanism 1 for rolling a carbon fiber sheet body 2, a mounting frame 3 arranged at the bottom of the rolling mechanism 1, and support plates 31 fixedly arranged at two symmetrical sides of the bottom of the mounting frame 3, and also includes: A winding mechanism 4, which is located on the mounting frame 3 and is used to quickly wind up the rolled carbon fiber sheet body 2; The rolling mechanism 1 includes a first pressing roller 11 and a second pressing roller 12, a first bracket 111 and a second bracket 112 fixedly arranged on both sides of the first pressing roller 11 and the second pressing roller 12, respectively, an electric cylinder 13 fixedly installed at the bottom of the first bracket 111 and fixedly connected to the top of the second bracket 112, and a control motor 14 fixedly arranged on one side of the first pressing roller 11 and the second pressing roller 12, and the carbon fiber sheet body 2 is located between the first pressing roller 11 and the second pressing roller 12; The coiling mechanism 4 includes a coiling roller 41 rotatably arranged on the support plate 31, an arc-shaped plate 42 arranged on the side of the coiling roller 41 close to the carbon fiber sheet body 2, a fixing component 43 located on the arc-shaped plate 42 for clamping the rolled carbon fiber sheet body 2, and a driving component 44 arranged on one side of the arc-shaped plate 42.

[0025] Adopting the above solution: during use, first pass the carbon fiber sheet body 2 to be rolled through the rolling mechanism 1. Specifically, pass it through the first pressing roller 11 and the second pressing roller 12. Adjust the distance between the first pressing roller 11 and the second pressing roller 12 by using the electric cylinder 13 according to the required rolling thickness. After the adjustment is completed, control the motor 14 to drive the first pressing roller 11 and the second pressing roller 12 to rotate simultaneously to realize the rolling and transmission of the carbon fiber sheet body 2. In order to avoid the inconvenience of storing the rolled carbon fiber sheet body 2, it can be automatically wound by using the coiling mechanism 4. The arc-shaped plate 42 is used to realize the reasonable diversion of the rolled carbon fiber sheet body 2, and the fixing component 43 is used to fix it. The driving component 44 drives the clamped carbon fiber sheet body 2 to closely adhere to the coiling roller 41 along the track of the arc-shaped plate 42. Start the rotating motor 411 to drive the coiling roller 41 to rotate, and release the carbon fiber sheet body 2 when the coiling roller 41 rotates to the position of the carbon fiber sheet body 2 to achieve the effect of automatic winding.

[0026] As Figure 6 shown, the coiling roller 41 is located between the two support plates 31. One end of the coiling roller 41 is fixedly provided with a rotating motor 411 fixedly connected to one side support plate 31. The bottom of the arc-shaped plate 42 is fixedly provided with a support block 421, and the support block 421 is fixedly connected to the bottom of the mounting frame 3. A central groove 422 is opened at the center of the arc-shaped plate 42, and a placement groove 423 is opened inside the central groove 422. The arc-shaped plate 42 is in a quarter-circular arc shape and is located on the outer wall of the coiling roller 41; The fixing component 43 includes a mounting plate 431, connecting circular plates 4311 fixedly arranged on both symmetric sides of the mounting plate 431, two clamping plates 432 symmetrically arranged on one side of the mounting plate 431 close to the carbon fiber sheet body 2, a cross bar 433 hinged at the edge near the top end of the clamping plate 432, a rectangular plate 434 fixedly arranged on the side of the cross bar 433 away from the mounting plate 431, an extension plate 435 fixedly arranged on the side of the connecting circular plate 4311 away from the mounting plate 431, and a first electric push rod 436 fixedly arranged on the extension plate 435 and fixedly connected to the bottom end of the clamping plate 432. The bottom of the cross bar 433 is fixedly connected to the extension plate 435. A connecting rod 4312 is fixedly arranged on the side of one connecting circular plate 4311 away from the mounting plate 431. A moving block 4313 that is slidably clamped with the placing groove 423 is fixedly arranged at the center of the mounting plate 431. The carbon fiber sheet body 2 passes between the arc plate 42 and the winding roller 41. A cutting component 45 for cutting the carbon fiber sheet body 2 is arranged on the top of the rectangular plate 434.

[0027] Adopting the above scheme: The fixing of the carbon fiber sheet body 2 after rolling is realized by using the fixing component 43. The carbon fiber sheet body 2 after rolling sags vertically by the action of gravity and falls to one side of the large arc plate 42. At this time, the first electric push rod 436 can be used to push the clamping plate 432 to make an angular offset along the position where the cross bar 433 is hinged, thereby driving the top of the clamping plate 432 to approach the mounting plate 431, realizing the clamping and fixing of the carbon fiber sheet body 2 at the center. The fixed carbon fiber sheet body 2 is driven by the driving component 44 to slide the moving block 4313 along the inside of the placing groove 423 and make a circular motion, pushing the carbon fiber sheet body 2 to be pulled along the surface of the winding roller 41, facilitating subsequent rotation and winding. During the winding process, the first electric push rod 436 is used to reset it to drive the clamping plate 432 to be in a vertical state, avoiding its contact with the carbon fiber sheet body 2 and affecting the winding.

[0028] As Figure 7 shown, the driving component 44 includes a connecting rod 441 fixedly arranged on the connecting rod 4312, a crank 442 clamped on the connecting rod 441, a fixed arc plate 443 fixedly arranged on one side of the mounting frame 3 and rotatably connected to the end of the connecting rod 441 away from the connecting rod 4312, a protruding arc plate 444 fixedly arranged on the side of the fixed arc plate 443 away from the mounting frame 3, and an adjusting motor 445 fixedly arranged on the protruding arc plate 444. The adjusting motor 445 is fixedly connected to the side of the crank 442 away from the connecting rod 441; The fixed arc plate 443 is in a quarter - circle shape, and an arc - shaped groove 4431 is opened on the fixed arc plate 443. The connecting rod 4312 slides along the arc - shaped groove 4431.

[0029] The above scheme is adopted: by utilizing the driving component 44 to realize traction of the fixed carbon fiber sheet body 2, utilizing the adjusting motor 445 to drive the crank 442 to rotate, thereby driving the connecting rod 441 to hinge with the fixed arc plate 443, so that it can make an arc motion synchronously with the connecting rod 4312, thereby driving the connecting rod 4312 to swing along the arc groove 4431, realizing the synchronous driving of the connecting circular plate 4311 and the mounting plate 431, and making the moving block 4313 slide back and forth along the center groove 422 on the arc plate 42, thereby realizing traction of the clamped carbon fiber sheet body 2, so that it can be close to the winding roller 41.

[0030] like Figure 8 As shown, the cutting assembly 45 includes a cutting knife 451 located on the top of the mounting plate 431, a vertical plate 452 slidably arranged on the top of the cross bar 433 and fixedly connected to both ends of the cutting knife 451, and a second electric push rod 453 fixedly arranged on the rectangular plate 434 for pushing the vertical plate 452 to move.

[0031] Adopt the above scheme: after the winding is completed, in order to avoid limited winding of the winding roller 41, the carbon fiber sheet body 2 can be quickly cut by utilizing the cutting assembly 45, and the carbon fiber sheet body 2 is clamped during the cutting process. After clamping, the second electric push rod 453 is used to push the vertical plate 452 to make it slide along the horizontal bar 433, thereby driving the cutting knife 451 to approach the carbon fiber sheet body 2 and quickly cut it.

[0032] The working principle and use process of the present invention are as follows: When using the device, first pass the carbon fiber sheet body 2 between the first pressing roller 11 and the second pressing roller 12. The electric cylinder 13 is used to adjust the distance between the two pressing rollers to accurately control the rolling thickness, and then the control motor 14 is started to drive the pressing roller to rotate, so as to achieve rapid rolling of the carbon fiber sheet. The rolled carbon fiber sheet falls vertically under the action of gravity, passes through the arc plate 42 and enters the gap between the clamping plate 432 and the mounting plate 431. At this time, the first electric push rod 436 pushes the clamping plate 432 to tilt so that its top is close to the mounting plate 431, thereby clamping the carbon fiber sheet body 2. After clamping, the motor 445 is adjusted to drive the crank 442 to rotate, driving the connecting rod 441 to swing around the winding roller 41, and at the same time connecting The rod 4312 slides along the arc groove 4431, causing the carbon fiber sheet body 2 to swing accordingly. When the carbon fiber sheet swings to the lowest position, the rotating motor 411 is started to drive the winding roller 41 to rotate, and the carbon fiber sheet is wound on the roller by inertia. At the same time, the motor drives the connecting rod 441 to reset, so that the mounting plate 431 returns to the initial position. After the winding is completed, the transmission of the first pressing roller 11 and the second pressing roller 12 is stopped, and the carbon fiber sheet body 2 is clamped by the fixing component 43. Finally, the cutting knife 451 is driven close to the carbon fiber sheet to complete the cutting operation. At this point, the use process of the entire device ends.

[0033] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
