Description

Technical Field

[0001] The present invention relates to the technical field of carbon fiber recycling, and in particular to a recycling device and method for thermosetting carbon fiber composite materials. Background Art

[0002] Carbon fiber composite materials use resin as the base material. Carbon fiber and resin are mixed and molded to obtain a lightweight and high-strength composite material. The finished carbon fiber composite material can be made into carbon fiber automotive parts, carbon fiber bicycles, etc. At present, most carbon fiber composite material recycling methods are pyrolysis, which uses electrical heating to remove the resin base material, thereby separating the high-value carbon fiber from it, thereby completing the recycling of carbon fiber;

[0003] Since the products made of carbon fiber composite materials have different volumes when they are heated and decomposed, the carbon fiber composite materials will be heated unevenly, thus affecting the recycling efficiency. Therefore, a recycling device and method for thermosetting carbon fiber composite materials are proposed to improve the recycling efficiency of carbon fiber composite materials. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a device and method for recycling thermosetting carbon fiber composite materials to improve the recycling efficiency of carbon fiber composite materials.

[0005] The technical solution adopted by the present invention to solve its technical problem is a recovery device for thermosetting carbon fiber composite materials, including a cutting structure, one side of the cutting structure is fixedly connected to a storage structure, a plurality of groups of horizontally arranged grille trays are arranged in the storage structure, a first conveying structure is arranged below the cutting structure and the storage structure, the grille tray is located above the first conveying structure, a roller conveyor belt is arranged on one side of the first conveying structure, a powered roller conveyor is arranged on the side of the roller conveyor belt away from the first conveying structure, a carbonization furnace is arranged on the side of the roller conveyor belt away from the cutting structure, the powered roller conveyor passes through the carbonization furnace, and an air purification device is connected above the carbonization furnace.

[0006] By adopting the above technical solution, the carbon fiber composite material to be recycled is placed in the cutting structure, and the carbon fiber composite material is cut into sections by moving the cutting structure, so that the carbon fiber composite material to be recycled is cut into specific lengths, which is convenient for subsequent heating and decomposition, thereby improving the recycling efficiency and meeting the recycling needs;

[0007] The cut carbon fiber composite material falls on the grid tray on the first conveying structure, and the cutting structure is reset to facilitate the next set of cutting. The cutting structure can drive the first conveying structure to move when it is reset. When the cut carbon fiber composite material falls on the grid tray, the grid tray is driven to move a certain distance by the reset movement of the cutting structure, so that the subsequent cut carbon fiber composite material is evenly laid on the grid tray without manual laying, and it is convenient to heat and decompose the carbon fiber composite material on the grid tray, so as to further improve the recycling efficiency and convenience of use.

[0008] When the carbon fiber composite materials on a group of grid trays are laid, the grid trays are moved to the roller conveyor belt, and the grid trays are transported to the carbonization furnace by the roller conveyor belt and the powered roller conveyor. The carbonization furnace heats and decomposes the carbon fiber composite materials placed on the grid trays, and the air purification device filters the pollutant gases generated during the heating and decomposition, thereby completing the recycling of the carbon fiber composite materials;

[0009] The grille tray at the bottom layer of the storage structure is placed on the first conveying structure, and the grille tray at the bottom layer is separated from the storage structure. When the cutting structure reciprocates and cuts, the first conveying structure is driven, and the grille tray at the bottom layer in the storage structure can be driven to move by the first conveying structure. When the grille tray at the bottom layer leaves the storage structure, another group of grille trays is separated and falls onto the first conveying structure, so that the grille trays in the storage structure are continuously moved out, and there is no need to manually place the grille tray under the cutting structure again, which further improves the convenience of use of the present invention.

[0010] It should be pointed out that before cutting the carbon fiber composite material, the grid tray should be driven to move directly under the cutting structure before the formal cutting of the carbon fiber composite material can be started.

[0011] Specifically, the cutting structure includes a support frame, a feed funnel is provided on the upper surface of the support frame, the feed funnel is communicated with the inside of the support frame, a limit plate is obliquely arranged inside the support frame, and the limit plate is fixedly connected to the inner wall of the support frame;

[0012] The support frame is provided with a symmetrical sliding groove, and the two groups of sliding grooves are both slidably connected to the sliding grooves, and a horizontally arranged moving plate is fixedly connected to the two groups of sliding grooves, and a connecting seat is provided on one side of the moving plate, and a sliding groove is arranged through it on the side of the moving plate close to the connecting seat. A spring rod is fixedly connected to the sliding groove, and one end of the spring rod is fixedly connected to the connecting seat. The lower end of the spring rod is fixedly connected to the connecting seat with two groups of vertically arranged positioning rods. The first return spring is sleeved on the positioning rod, and the upper part of the positioning rod is sleeved with a supporting ring, and the lower surface of the supporting ring is pressed and contacted with the upper end of the first return spring. A horizontally arranged cutting blade is provided on the upper surface of the connecting seat, and the upper end of the positioning rod passes through the cutting blade, and the supporting ring is fixedly connected to the cutting blade, and a nut is threadedly connected to the upper end of the positioning rod, and the lower surface of the nut is pressed and contacted with the upper surface of the cutting blade.

[0013] A vertically arranged baffle is provided inside the support frame, and a plurality of cutting grooves are provided on a side of the baffle close to the cutting blade. The cutting blade is squeezed and contacted with the baffle after movement. An electric telescopic rod is fixedly connected to the outer side of the support frame, and the output end of the electric telescopic rod passes through the support frame and is fixedly connected to a side of the moving plate away from the connecting seat. An inclined discharge plate is provided at the lower part of the support frame, and a discharge port is provided on one side of the discharge plate.

[0014] By adopting the above technical solution, the carbon fiber composite material to be recycled is placed into the support frame through the feeding funnel. When the carbon fiber composite material enters the support frame, one end of the carbon fiber composite material contacts the upper surface of the moving plate. At this time, the limit plate can be used to improve the stability of the carbon fiber composite material and facilitate the subsequent cutting blade to cut it in sections.

[0015] After the carbon fiber composite material enters the support frame, the electric telescopic rod drives the moving plate to move. When the moving plate moves, the slider and the slide groove can improve the moving stability of the moving plate. When the moving plate moves, the spring rod drives the connecting seat and the cutting blade to move synchronously. When the moving plate moves to a certain position, the cutting blade cuts the carbon fiber composite material. At the same time, the baffle and the cutting groove can ensure that the cutting blade cuts the carbon fiber composite material in sections. At this time, the cut carbon fiber composite material falls on the upper surface of the moving plate, and the cutting of the carbon fiber composite material is completed at the same time.

[0016] When the carbon fiber composite material falls onto the upper surface of the movable plate, as the electric telescopic rod continues to drive the movable plate to move, the cutting blade is squeezed and contacted with the baffle plate, so that the connecting seat cannot continue to move with the movable plate. As the movable plate moves, the spring rod is stretched, and as the movable plate moves to a certain position, the carbon fiber composite material on the movable plate is squeezed and contacted with the lower side of the baffle plate, and is separated from the upper surface of the movable plate and falls onto the discharge plate of the support frame. The cut carbon fiber composite material is discharged through the discharge port by the inclined discharge plate and falls onto the upper surface of the grid tray.

[0017] The electric telescopic rod drives the moving plate to reset and move. When the moving plate resets and moves, the transmission structure drives the first conveying structure, and the first conveying structure drives the grid tray to move a certain distance, so as to facilitate the subsequent acceptance of the next section of the cut carbon fiber composite material, thereby improving the convenience of use;

[0018] The position of the nut is adjusted by turning the nut, and the position of the cutting blade is adjusted by the squeezing of the first return spring, so that the cutting size of the carbon fiber composite material to be recycled can be adjusted according to the different cutting requirements of the carbon fiber composite material, thereby further improving the convenience of use, facilitating subsequent heating and decomposition, and meeting the needs of carbon fiber recycling processing.

[0019] Specifically, the storage structure includes a storage frame, an opening is provided on the upper surface of the storage frame, a side of the storage frame close to the support frame is fixedly connected to the support frame, a plurality of groups of horizontally arranged grille trays are provided in the storage frame, adjacent grille trays are stacked inside the storage frame, and the lowest grille tray in the storage frame is rollingly connected to the first conveying structure.

[0020] By adopting the above technical scheme, when the cut carbon fiber composite material is discharged through the discharge port and falls on the grid tray, the electric telescopic rod is used to drive the movable plate to reset and move. When the movable plate resets and moves, it drives the first conveying structure, and the first conveying structure is used to drive the grid tray and the grid tray at the bottom of the storage structure to move a certain distance, so as to continuously move the grid tray in the storage structure out, so as to facilitate the reception of the cut carbon fiber composite material, and there is no need to manually place the grid tray under the cutting structure again, thereby further improving the ease of use of the present invention.

[0021] Specifically, the first conveying structure includes two groups of connecting plates, a plurality of groups of conveying rollers are rotatably connected between the two groups of connecting plates, adjacent conveying rollers are driven by pulleys, and a plurality of groups of supporting legs are fixedly connected to the lower part of the connecting plates;

[0022] Both ends of one group of the conveying rollers are connected to the first pulley, and a group of horizontally arranged output shafts are respectively provided above the two groups of the first pulleys, the output shafts are rotatably connected to the support frame, one end of the output shaft is fixedly connected to the second pulley, the first pulley and the second pulley are driven by a transmission belt, the end of the output shaft away from the second pulley passes through the support frame and is provided with a first gear, the first gear is fixedly connected to the output shaft via a one-way bearing, and a transmission structure is provided at the lower part of the movable plate, and the first gear is transmitted by the transmission structure.

[0023] By adopting the above technical solution, when the cut carbon fiber composite material falls on the upper surface of the movable plate, as the electric telescopic rod continues to drive the movable plate to move, the carbon fiber composite material on the movable plate is squeezed and contacted with the lower side of the baffle, so that the carbon fiber composite material is separated from the movable plate and falls on the grid tray;

[0024] When the movable plate is reset and moved, the transmission structure drives the first gear to rotate. When the first gear rotates, the one-way bearing drives the output shaft to rotate unidirectionally. When the output shaft rotates, the second pulley and the transmission belt drive the first pulley to rotate. When the first pulley rotates, it drives the corresponding conveying roller to rotate. When a group of conveying rollers rotates, the pulley drives the adjacent conveying rollers to rotate, thereby driving several groups of conveying rollers to rotate. At the same time, the rotation of several groups of conveying rollers drives the grid tray to move, so that the grid tray can subsequently receive the cut carbon fiber composite material, further improving the convenience of use.

[0025] Specifically, the transmission structure includes a mounting groove symmetrically arranged on the lower surface of the movable plate, a first rack and a second rack are provided in the mounting groove, the first rack is fixedly connected to the inside of the mounting groove, the second rack is slidably connected to the inner wall of the mounting groove, one side of the first gear is meshed with a second gear, the second gear is rotatably connected to the inner wall of the support frame, the first rack and the second rack are meshed with the second gear, and an adjustment structure is provided in the mounting groove, and the adjustment structure is used to drive the second rack to move.

[0026] By adopting the above technical solution, the electric telescopic rod drives the moving plate and the cutting blade to move synchronously. When the moving plate moves to a certain position, the cutting blade cuts the carbon fiber composite material. At the same time, the first rack and the second rack installed on the lower surface of the moving plate mesh with the second gear and drive the first gear. At this time, the one-way bearing is used to prevent the output shaft from being driven to rotate.

[0027] When the cut carbon fiber composite material falls on the grille tray, the electric telescopic rod drives the moving plate to reset and move. When the moving plate resets and moves, the first rack and the second rack installed on the lower surface of the moving plate mesh with the second gear again for transmission. When the second gear drives the first gear to rotate, it relies on the one-way bearing to drive the output shaft to rotate synchronously. When the output shaft rotates, it relies on the second pulley and the transmission belt to drive the first pulley to rotate. When the first pulley rotates, it drives the corresponding conveying roller to rotate, thereby driving several groups of conveying rollers to rotate. At the same time, the grille tray is driven to move by the rotation of several groups of conveying rollers, so that the grille tray can subsequently receive the cut carbon fiber composite material.

[0028] The position of the second rack in the mounting groove can be adjusted by means of the adjustment structure so that the second rack is staggered with the first rack, thereby adjusting the transmission time of the transmission structure and the second gear, thereby automatically adjusting the single movement distance of the grid tray according to the cutting size of the carbon fiber composite material, so as to facilitate the even laying of the cut carbon fiber composite material on the grid tray.

[0029] Specifically, the adjustment structure includes a first hydraulic telescopic rod installed on the upper surface of the connecting seat, the output end of the first hydraulic telescopic rod is connected to the lower surface of the cutting blade, a second hydraulic telescopic rod arranged horizontally is fixedly connected in the mounting groove, the output end of the second hydraulic telescopic rod is fixedly connected to one side of the second rack, a second return spring is fixedly connected to the side of the second rack away from the second hydraulic telescopic rod, one end of the second return spring is fixedly connected to the inner wall of the mounting groove, and the interior of the fixed end of the first hydraulic telescopic rod is connected to the interior of the fixed end of the second hydraulic telescopic rod through a connecting joint and a pipeline.

[0030] By adopting the above technical solution, the position of the cutting blade can be easily adjusted by turning the nut;

[0031] When the cutting blade moves downward, the first hydraulic telescopic rod is squeezed to shorten, and the second hydraulic telescopic rod is driven to extend by the connecting joint and the pipeline. When the second hydraulic telescopic rod extends, the second rack is squeezed to move, thereby reducing the meshing transmission time between the transmission structure and the second gear, and thereby adjusting the single movement distance of the grid tray driven by the conveying roller;

[0032] On the contrary, when the cutting blade is adjusted to move upward by relying on the first return spring and the nut, the output end of the first hydraulic telescopic rod is no longer squeezed, and the second hydraulic telescopic rod is shortened by relying on the second return spring, and the first hydraulic telescopic rod is driven to extend again by relying on the connecting joint and the pipeline. When the second hydraulic telescopic rod is shortened, it drives the second rack to move, thereby increasing the transmission time of the transmission structure and the second gear, and thereby increasing the single movement distance of the grille tray, so that the single movement distance of the grille tray can be adjusted according to the cutting size of the carbon fiber composite material by the cutting blade, so that the grille tray can receive and lay the cut carbon fiber composite material, thereby further improving the convenience of use.

[0033] Specifically, an inspection opening is provided on the upper surface of the support frame, and the inspection opening is communicated with the interior of the support frame.

[0034] By adopting the above technical solution, the nut can be easily screwed by opening the inspection port to adjust the position of the cutting blade, thereby adjusting the cutting size of the carbon fiber composite material.

[0035] A method for recycling thermosetting carbon fiber composite materials, using the above-mentioned device for recycling thermosetting carbon fiber composite materials, specifically comprises the following steps:

[0036] Step 1: Adjust the cutting structure according to the recycling requirements of carbon fiber composite materials;

[0037] Step 2: pour the carbon fiber composite material into the cutting structure;

[0038] Step 3: While starting the cutting structure to cut the carbon fiber composite material, the grid tray is continuously transported;

[0039] Step 4: Use a powered roller conveyor to transport the grid tray supporting the cut carbon fiber composite material to the carbonization furnace;

[0040] Step 5: After the carbonization furnace pyrolyzes the carbon fiber composite material, the powered roller conveyor moves the grid tray out of the carbonization furnace.

DETAILED DESCRIPTION

[0058] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0059] In order to improve the recycling efficiency of carbon fiber composite materials, as an embodiment of the present invention, Figure 1 As shown, a recovery device for thermosetting carbon fiber composite materials described in the present invention includes a cutting structure, one side of the cutting structure is fixedly connected to a storage structure, a plurality of groups of horizontally arranged grille trays 1 are arranged in the storage structure, a first conveying structure is arranged below the cutting structure and the storage structure, the grille tray 1 is located above the first conveying structure, a roller conveyor belt 2 is arranged on one side of the first conveying structure, a powered roller conveyor 3 is arranged on the side of the roller conveyor belt 2 away from the first conveying structure, a carbonization furnace 4 is arranged on the side of the roller conveyor belt 2 away from the cutting structure, the powered roller conveyor 3 passes through the carbonization furnace 4, and an air purification device 5 is connected above the carbonization furnace 4.

[0060] When in use, the carbon fiber composite material to be recycled is placed in the cutting structure, and the carbon fiber composite material is cut into sections by moving the cutting structure, so that the carbon fiber composite material to be recycled is cut into specific lengths, which is convenient for subsequent heating and decomposition, thereby improving recycling efficiency and meeting recycling needs;

[0061] The cut carbon fiber composite material falls on the grid tray 1 on the first conveying structure, and the cutting structure is reset to facilitate the next set of cutting. The cutting structure can drive the first conveying structure to move when it is reset. When the cut carbon fiber composite material falls on the grid tray 1, the grid tray 1 is driven to move a certain distance by the reset movement of the cutting structure, so that the subsequent cut carbon fiber composite material is evenly laid on the grid tray 1 without manual laying, and it is convenient to heat and decompose the carbon fiber composite material on the grid tray 1, further improving the recycling efficiency and convenience of use.

[0062] When the carbon fiber composite material on a group of grid trays 1 is laid, the grid tray 1 is moved to the roller conveyor belt 2, and the grid tray 1 is transported to the carbonization furnace 4 by the roller conveyor belt 2 and the powered roller conveyor 3. The carbon fiber composite material placed on the grid tray 1 is heated and decomposed by the carbonization furnace 4, and the pollutant gas generated during the heating and decomposition is filtered by the air purification device 5, so as to complete the recovery of the carbon fiber composite material;

[0063] The grille pallet 1 at the bottom layer of the storage structure is placed on the first conveying structure, and the grille pallet 1 at the bottom layer is separated from the storage structure. When the cutting structure moves back and forth, it drives the first conveying structure, and can rely on the first conveying structure to drive the grille pallet 1 at the bottom layer in the storage structure to move. When the grille pallet 1 at the bottom layer leaves the bottom of the storage structure, another group of grille pallets detach and fall onto the first conveying structure, thereby continuously moving the grille pallets 1 in the storage structure out, and there is no need to manually place the grille pallet 1 under the cutting structure again, thereby further improving the ease of use of the present invention.

[0064] In order to facilitate the segmented cutting of the carbon fiber composite material, for example, Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 , Fig.11 As shown, the present invention also includes that the cutting structure includes a support frame 6, a feed funnel 7 is provided on the upper surface of the support frame 6, the feed funnel 7 is communicated with the inside of the support frame 6, a limit plate 8 is obliquely arranged inside the support frame 6, and the limit plate 8 is fixedly connected to the inner wall of the support frame 6;

[0065] The support frame 6 is provided with symmetrically arranged slide grooves 9 inside, and sliders are slidably connected in the two groups of the slide grooves 9, and a horizontally arranged moving plate 10 is fixedly connected between the two groups of the sliders, and a connecting seat 11 is provided on one side of the moving plate 10, and a sliding groove 12 is provided on the side of the moving plate 10 close to the connecting seat 11, and a spring rod 13 is fixedly connected in the sliding groove 12, and one end of the spring rod 13 is fixedly connected to the connecting seat 11, and two groups of vertically arranged positioning rods 14 are fixedly connected to the upper surface of the connecting seat 11, and the lower end of the positioning rod 14 is fixedly connected to the connecting seat 11. The connecting seat 11 is fixedly connected, the positioning rod 14 is sleeved with a first return spring 15, the upper part of the positioning rod 14 is sleeved with a support ring 16, the lower surface of the support ring 16 is in compression contact with the upper end of the first return spring 15, the upper surface of the connecting seat 11 is provided with a horizontally arranged cutting blade 17, the upper end of the positioning rod 14 passes through the cutting blade 17, the support ring 16 is fixedly connected to the cutting blade 17, the upper end of the positioning rod 14 is threadedly connected with a nut 18, and the lower surface of the nut 18 is in compression contact with the upper surface of the cutting blade 17;

[0066] A vertically arranged baffle 19 is provided inside the support frame 6, and a plurality of cutting grooves 20 are provided on a side of the baffle 19 close to the cutting blade 17. The cutting blade 17 is squeezed and contacted with the baffle 19 after movement. An electric telescopic rod 21 is fixedly connected to the outer side of the support frame 6, and an output end of the electric telescopic rod 21 passes through the support frame 6 and is fixedly connected to a side of the moving plate 10 away from the connecting seat 11. An inclined discharge plate 22 is provided at the lower part of the support frame 6, and a discharge port 23 is provided on one side of the discharge plate 22.

[0067] When in use, the carbon fiber composite material to be recycled is placed into the support frame 6 through the feed funnel 7. After the carbon fiber composite material enters the support frame 6, one end of the carbon fiber composite material contacts the upper surface of the movable plate 10. At this time, the limit plate 8 can improve the stability of the carbon fiber composite material and facilitate the subsequent cutting blade 17 to cut it in sections.

[0068] After the carbon fiber composite material enters the support frame 6, the electric telescopic rod 21 drives the moving plate 10 to move. When the moving plate 10 moves, the slider and the slide groove 9 can improve the moving stability of the moving plate 10. When the moving plate 10 moves, the spring rod 13 drives the connecting seat 11 and the cutting blade 17 to move synchronously. When the moving plate 10 moves to a certain position, the cutting blade 17 cuts the carbon fiber composite material. At the same time, the baffle 19 and the cutting groove 20 can ensure that the cutting blade 17 cuts the carbon fiber composite material in sections. At this time, the cut carbon fiber composite material falls on the upper surface of the moving plate 10, and the cutting of the carbon fiber composite material is completed at the same time.

[0069] After the carbon fiber composite material falls on the upper surface of the movable plate 10, as the electric telescopic rod 21 continues to drive the movable plate 10 to move, the cutting blade 17 is squeezed and contacted with the baffle plate 19, so that the connecting seat 11 cannot continue to move with the movable plate 10. As the movable plate 10 moves, the spring rod 13 is stretched, and as the movable plate 10 moves to a certain position, the carbon fiber composite material on the movable plate 10 is squeezed and contacted with the lower side of the baffle plate 19, and is separated from the upper surface of the movable plate 10, and falls on the discharge plate 22 of the support frame 6. The cut carbon fiber composite material is discharged through the discharge port 23 by the inclined discharge plate 22, and falls on the upper surface of the grid tray 1;

[0070] The electric telescopic rod 21 drives the moving plate 10 to reset and move. When the moving plate 10 resets and moves, the transmission structure drives the first conveying structure, and the first conveying structure drives the grid tray 1 to move a certain distance, so as to facilitate the subsequent acceptance of the next section of the cut carbon fiber composite material, thereby improving the convenience of use;

[0071] The position of the nut 18 is adjusted by turning the nut 18, and the position of the cutting blade 17 is adjusted by the squeezing of the first return spring 15, so as to adjust the cutting size of the carbon fiber composite material to be recycled according to the different cutting requirements of the carbon fiber composite material, further improve the convenience of use, facilitate the subsequent heating decomposition, and meet the needs of carbon fiber recycling processing.

[0072] In order to facilitate the acceptance of the cut carbon fiber composite material, for example, Figure 1 , Figure 5 , Fig. 9 As shown, the present invention also includes that the storage structure includes a storage frame 24, the upper surface of the storage frame 24 is provided with an opening 25 set through, the side of the storage frame 24 close to the support frame 6 is fixedly connected to the support frame 6, and a plurality of groups of horizontally arranged grille trays 1 are provided in the storage frame 24, and adjacent grille trays 1 are stacked inside the storage frame 24, and the bottom grille tray 1 in the storage frame 24 is rollingly connected to the first conveying structure.

[0073] During use, when the cut carbon fiber composite material is discharged through the discharge port 23 and falls on the grid tray 1, the electric telescopic rod 21 drives the movable plate 10 to reset and move. When the movable plate 10 resets and moves, it drives the first conveying structure, and relies on the first conveying structure to drive the grid tray 1 and the grid tray 1 located at the bottom of the storage structure to move a certain distance, so as to continuously move the grid tray 1 in the storage structure out, so as to facilitate the reception of the cut carbon fiber composite material, and there is no need to manually place the grid tray 1 under the cutting structure again, which further improves the convenience of use of the present invention.

[0074] In order to facilitate the movement of the grille tray 1, for example, Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 , Fig.11 As shown, the present invention also includes that the first conveying structure includes two groups of connecting plates 26, a plurality of groups of conveying rollers 27 are rotatably connected between the two groups of connecting plates 26, and adjacent conveying rollers 27 are driven by pulleys 28, and a plurality of groups of supporting legs 29 are fixedly connected to the lower part of the connecting plates 26;

[0075] Both ends of one group of the conveying rollers 27 are connected to the first pulley 30, and a group of horizontally arranged output shafts 31 are respectively provided above the two groups of the first pulleys 30. The output shafts 31 are rotatably connected to the support frame 6, and one end of the output shaft 31 is fixedly connected to the second pulley 32. The first pulley 30 and the second pulley 32 are transmitted by a transmission belt 33. The end of the output shaft 31 away from the second pulley 32 passes through the support frame 6 and is provided with a first gear 34. The first gear 34 is fixedly connected to the output shaft 31 through a one-way bearing 35. A transmission structure is provided at the lower part of the movable plate 10, and the first gear 34 is transmitted to the transmission structure.

[0076] When in use, after the cut carbon fiber composite material falls on the upper surface of the moving plate 10, as the electric telescopic rod 21 continues to drive the moving plate 10 to move, the carbon fiber composite material on the moving plate 10 is squeezed and contacted with one side of the lower part of the baffle 19, so that the carbon fiber composite material is separated from the moving plate 10 and falls on the grid tray 1;

[0077] When the movable plate 10 is reset and moved, the transmission structure drives the first gear 34 to rotate. When the first gear 34 rotates, the one-way bearing 35 drives the output shaft 31 to rotate in one direction. When the output shaft 31 rotates, the second pulley 32 and the transmission belt 33 drive the first pulley 30 to rotate. When the first pulley 30 rotates, it drives the corresponding conveying roller 27 to rotate. When a group of conveying rollers 27 rotates, the pulley 28 drives the adjacent conveying rollers 27 to rotate, thereby driving several groups of conveying rollers 27 to rotate. At the same time, the rotation of several groups of conveying rollers 27 drives the grille tray 1 to move, so that the grille tray 1 can subsequently receive the cut carbon fiber composite material, further improving the convenience of use.

[0078] As an embodiment of the present invention, Figure 5 , Figure 8 , Fig. 9As shown, the present invention also includes that the transmission structure includes a mounting groove 36 symmetrically arranged on the lower surface of the movable plate 10, and a first rack 37 and a second rack 38 are provided in the mounting groove 36, the first rack 37 is fixedly connected to the inside of the mounting groove 36, the second rack 38 is slidably connected to the inner wall of the mounting groove 36, one side of the first gear 34 is meshed with a second gear 44, the second gear 44 is rotatably connected to the inner wall of the support frame 6, the first rack 37 and the second rack 38 are meshed with the second gear 44 for transmission, and an adjustment structure is provided in the mounting groove 36, and the adjustment structure is used to drive the second rack 38 to move.

[0079] When in use, the electric telescopic rod 21 drives the moving plate 10 and the cutting blade 17 to move synchronously. When the moving plate 10 moves to a certain position, the cutting blade 17 cuts the carbon fiber composite material. At the same time, the first rack 37 and the second rack 38 installed on the lower surface of the moving plate 10 mesh with the second gear 44 and drive the first gear 34. At this time, the one-way bearing 35 is used to prevent the output shaft 31 from being driven to rotate.

[0080] When the cut carbon fiber composite material falls on the grille tray 1, the electric telescopic rod 21 drives the movable plate 10 to reset and move. When the movable plate 10 resets and moves, the first rack 37 and the second rack 38 installed on the lower surface of the movable plate 10 mesh with the second gear 44 again for transmission. When the second gear 44 drives the first gear 34 to rotate, it drives the output shaft 31 to rotate synchronously by the one-way bearing 35. When the output shaft 31 rotates, it drives the first pulley 30 to rotate by the second pulley 32 and the transmission belt 33. When the first pulley 30 rotates, it drives the corresponding conveying roller 27 to rotate, thereby driving several groups of conveying rollers 27 to rotate. At the same time, the grille tray 1 is driven to move by the rotation of several groups of conveying rollers 27, so that the grille tray 1 can subsequently receive the cut carbon fiber composite material.

[0081] The position of the second rack 38 in the mounting groove 36 can be adjusted by means of the adjustment structure so that the second rack 38 is staggered with the first rack 37, thereby adjusting the transmission time of the transmission structure and the second gear 44, thereby automatically adjusting the single movement distance of the grid tray 1 according to the cutting size of the carbon fiber composite material, so as to facilitate the even laying of the cut carbon fiber composite material on the grid tray 1.

[0082] In order to facilitate the adjustment of the single movement distance of the grid tray 1, for example, Figure 5 , Figure 8 , Fig. 9As shown, the present invention also includes that the adjustment structure includes a first hydraulic telescopic rod 39 installed on the upper surface of the connecting seat 11, the output end of the first hydraulic telescopic rod 39 is connected to the lower surface of the cutting blade 17, and a horizontally arranged second hydraulic telescopic rod 40 is fixedly connected in the mounting groove 36, the output end of the second hydraulic telescopic rod 40 is fixedly connected to one side of the second rack 38, and a second return spring 41 is fixedly connected to the side of the second rack 38 away from the second hydraulic telescopic rod 40, one end of the second return spring 41 is fixedly connected to the inner wall of the mounting groove 36, and the interior of the fixed end of the first hydraulic telescopic rod 39 is connected to the interior of the fixed end of the second hydraulic telescopic rod 40 through a connecting joint 42 and a pipeline.

[0083] When in use, the position of the cutting blade 17 can be easily adjusted by turning the nut 18;

[0084] When the cutting blade 17 moves downward, the first hydraulic telescopic rod 39 is squeezed to shorten, and the second hydraulic telescopic rod 40 is driven to extend by the connecting joint 42 and the pipeline. When the second hydraulic telescopic rod 40 extends, the second rack 38 is squeezed to move, thereby reducing the meshing transmission time between the transmission structure and the second gear 44, and thereby adjusting the single movement distance of the grid tray 1 driven by the conveying roller 27;

[0085] On the contrary, when the cutting blade 17 is adjusted to move upward by relying on the first return spring 15 and the nut 18, the output end of the first hydraulic telescopic rod 39 is no longer squeezed, and the second hydraulic telescopic rod 40 is shortened by relying on the second return spring 41, and the first hydraulic telescopic rod 39 is driven to extend again by relying on the connecting joint 42 and the pipeline. When the second hydraulic telescopic rod 40 is shortened, it drives the second rack 38 to move, thereby increasing the transmission time of the transmission structure and the second gear 44, and thereby increasing the single movement distance of the grille tray 1. In this way, the single movement distance of the grille tray 1 can be adjusted according to the cutting size of the carbon fiber composite material by the cutting blade 17, so that the grille tray 1 can receive and lay the cut carbon fiber composite material, thereby further improving the convenience of use.

[0086] For example, Figure 1 As shown, the present invention also includes that an inspection opening 43 is provided on the upper surface of the support frame 6 , and the inspection opening 43 is connected to the inside of the support frame 6 .

[0087] When in use, the nut 18 is conveniently screwed by opening the inspection port 43 to adjust the position of the cutting blade 17, thereby adjusting the cutting size of the carbon fiber composite material.

[0088] A method for recycling thermosetting carbon fiber composite materials, using the above-mentioned device for recycling thermosetting carbon fiber composite materials, specifically comprises the following steps:

[0089] Step 1: Adjust the cutting structure according to the recycling requirements of the thermosetting carbon fiber composite material;

[0090] Step 2: pouring the thermosetting carbon fiber composite material into the cutting structure;

[0091] Step 3: while starting the cutting structure to cut the thermosetting carbon fiber composite material, the grid tray 2 is continuously transported;

[0092] Step 4: Using a powered roller conveyor 3, the grid tray 2 supporting the cut thermosetting carbon fiber composite material is conveyed to the carbonization furnace 4;

[0093] Step 5: After the carbonization furnace 4 pyrolyzes the thermosetting carbon fiber composite material, the powered roller conveyor 3 moves the grid tray 2 out of the carbonization furnace 4 .

[0094] When the present invention is used, the carbon fiber composite material to be recycled is placed into the support frame 6 through the feed funnel 7. After the carbon fiber composite material enters the support frame 6, one end of the carbon fiber composite material contacts the upper surface of the moving plate 10. At this time, the limit plate 8 can improve the stability of the carbon fiber composite material and facilitate the subsequent cutting blade 17 to cut it in sections.

[0095] After the carbon fiber composite material enters the support frame 6, the electric telescopic rod 21 drives the moving plate 10 to move. When the moving plate 10 moves, the slider and the slide groove 9 can improve the moving stability of the moving plate 10. When the moving plate 10 moves, the spring rod 13 drives the connecting seat 11 and the cutting blade 17 to move synchronously. When the moving plate 10 moves to a certain position, the cutting blade 17 cuts the carbon fiber composite material. At the same time, the baffle 19 and the cutting groove 20 can ensure that the cutting blade 17 cuts the carbon fiber composite material in sections. At this time, the cut carbon fiber composite material falls on the upper surface of the moving plate 10, and the cutting of the carbon fiber composite material is completed at the same time.

[0096] After the carbon fiber composite material falls on the upper surface of the movable plate 10, as the electric telescopic rod 21 continues to drive the movable plate 10 to move, the cutting blade 17 is squeezed and contacted with the baffle plate, so that the connecting seat 11 cannot continue to move with the movable plate 10. As the movable plate 10 moves, the spring rod 13 is stretched, and as the movable plate 10 moves to a certain position, the carbon fiber composite material on the movable plate 10 is squeezed and contacted with the lower side of the baffle plate 19, and is separated from the upper surface of the movable plate 10, and falls on the discharge plate 22 of the support frame 6. The cut carbon fiber composite material is discharged through the discharge port 23 by the inclined discharge plate 22, and falls on the upper surface of the grid tray 1;

[0097] The electric telescopic rod 21 drives the moving plate 10 and the cutting blade 17 to move synchronously. When the moving plate 10 moves to a certain position, the cutting blade 17 cuts the carbon fiber composite material. At the same time, the first rack 37 and the second rack 38 installed on the lower surface of the moving plate 10 mesh with the second gear 44 and drive the first gear 34. At this time, the one-way bearing 35 is relied on to prevent the output shaft 31 from being driven to rotate;

[0098] After the cut carbon fiber composite material falls on the grille tray 1, the electric telescopic rod 21 drives the movable plate 10 to reset and move. When the movable plate 10 resets and moves, the first rack 37 and the second rack 38 installed on the lower surface of the movable plate 10 are meshed and transmitted with the second gear 44 again. When the second gear 44 rotates, it drives the output shaft 31 to rotate synchronously by the one-way bearing 35. When the output shaft 31 rotates, it drives the first pulley 30 to rotate by the second pulley 32 and the transmission belt 33. When the first pulley 30 rotates, it drives the corresponding conveying roller 27 to rotate, thereby driving several groups of conveying rollers 27 to rotate. At the same time, the grille tray 1 is driven to move by the rotation of several groups of conveying rollers 27, so that the grille tray 1 can subsequently receive the cut carbon fiber composite material.

[0099] When the carbon fiber composite material on a group of grid trays 1 is laid, the grid tray 1 is moved to the roller conveyor belt 2, and the grid tray 1 is transported to the carbonization furnace by the roller conveyor belt 2 and the powered roller conveyor 3. The carbon fiber composite material placed on the grid tray 1 is heated and decomposed by the carbonization furnace, and the pollutant gas generated during the heating and decomposition is filtered by the air purification device 5, so as to complete the recovery of the carbon fiber composite material;

[0100] By screwing the nut 18, the position of the cutting blade 17 can be adjusted conveniently, so as to adjust the cutting size of the carbon fiber composite material to be recycled according to the different cutting requirements of the carbon fiber composite material. At the same time, by adjusting the position of the cutting blade 17, the position of the second rack 38 in the mounting groove 36 can be adjusted so that the second rack 38 is staggered with the first rack 37, so as to adjust the transmission time of the transmission structure and the second gear 44, thereby automatically adjusting the single movement distance of the grid tray 1 according to the cutting size of the carbon fiber composite material, so as to facilitate the even laying of the cut carbon fiber composite material on the grid tray 1, thereby further improving the convenience of use.
