Description

Technical Field

[0001] The invention relates to the technical field of plastic molding, and in particular to production equipment and a process for a carbon fiber heating material. Background Art

[0002] Carbon fiber composite materials have a series of characteristics such as light weight, high strength, corrosion resistance, and designability, and are widely used in aerospace, national defense, military, automotive industry, medical equipment, sports and leisure, etc. Carbon fiber laminates are the most important form of composite material application, and laminates are generally prepared by molding process.

[0003] The existing technical solutions still have the following deficiencies in the process of molding carbon fiber composite materials:

[0004] 1. During the heating and forming process, since the mold and the mold plate still have residual high temperature, the molding material still sticks to the mold at high temperature. During the demoulding process, the staff can easily be burned, which not only reduces the efficiency of thermoforming but also increases the difficulty of demoulding;

[0005] 2. The material after demoulding still has a certain temperature, and the staff needs to wear thermal insulation protective clothing to operate, which not only affects the handling of the molding material, but also increases the cost of handling;

Then, when the lifting plate pushes the molding materials and the pad above it upward, the trapezoidal transmission rod contacts the blocking plate, and the trapezoidal transmission rod and the pushing plate are both in a stationary state. After the molding materials are stacked, the pad can form a gap between two adjacent molding materials for ventilation, which not only accelerates cooling but also facilitates later transportation.

DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] Example 1: Reference Figure 1 and Figure 2, production equipment, which is used in the field of composite material production equipment, designs a stable workbench 1, the top of which is vertically fixed with a top plate 2 through multiple support columns to ensure that the top plate 2 is stable and does not shake. In the center position of the top plate 2, a cylinder 3 is fixedly installed through it, and the output shaft of the cylinder 3 extends downward and is fixedly connected to a mold plate 4. A carbon fiber electric heating plate 5 is tightly installed on the bottom of the mold plate 4 to provide a heating function. A plurality of sliding rods 6 are welded on the top of the mold plate 4. The top ends of these sliding rods 6 pass through the top plate 2 and are slidably connected to it, ensuring that the mold plate 4 can be smoothly raised and lowered under the drive of the cylinder 3.

[0048] Reference Figure 1-Figure 3 A rectangular hole 7 is provided inside the workbench 1, and a mold box 12 is detachably placed inside the rectangular hole 7. The mold box 12 is used to place the material to be hot-pressed. The mold box 12 cooperates with the mold pressing plate 4 and the carbon fiber electric heating plate 5. When the mold pressing plate 4 descends, the carbon fiber electric heating plate 5 heats the material in the mold box 12 and performs mold pressing.

[0049] Reference Figure 1 , Figure 2 and Figure 7 A cooling box 27 is installed under the workbench 1. The cooling box 27 is filled with cooling water to quickly cool the formed material. Two parallel rotating rollers 28 are arranged in the cooling box 27. The outer walls of the rotating rollers 28 are connected to two conveyor belts 29 through a transmission device to form a continuous conveying path for conveying the formed and cooled material to a designated location. Two frames 34 are fixed on the top of one side of the cooling box 27. The frames 34 are used to support and stack the cooled formed material.

[0050] Reference Figure 3-Figure 5 The demoulding structure includes two rotating shafts 8 respectively installed on the inner walls of both sides of the rectangular hole 7, and one end of the rotating shaft 8 is fixedly connected to the turntable 9. A plurality of fixed columns 10 are fixed on the near surface of the turntable 9, and the other ends of the fixed columns 10 are connected to the first fixed plate 11. The two first fixed plates 11 are respectively fixed on both sides of the mold box 12. The rotation of the rotating shaft 8 drives the turntable 9 and the first fixed plate 11 to rotate, thereby driving the mold box 12 to rotate. Two transmission grooves 14 are provided in the workbench 1, and the other end of the rotating shaft 8 extends into the transmission groove 14, and a first gear 16 is fixedly sleeved on the outer wall thereof. Two moving grooves 15 connected to the transmission groove 14 are provided on the top of the workbench 1, and a second fixed plate 23 is slidably installed in the moving groove 15, and a first rack 24 is fixed at the bottom of the second fixed plate 23, and the first rack 24 is meshed with the first gear 16. By moving the second fixed plate 23, the first rack 24 drives the first gear 16 to rotate, thereby driving the rotating shaft 8 and the mold box 12 to rotate.

[0051] Reference Figure 3-Figure 6The demoulding structure also includes two vertical plates 18 fixed on the top of the workbench 1, and a trapezoidal extrusion plate 19 is slidably installed between the vertical plates 18. A rectangular groove 20 is provided in the vertical plate 18, and a screw rod 21 is rotatably installed in the rectangular groove 20. One end of the screw rod 21 extends to the outside of the vertical plate 18, and the two screw rods 21 are connected by a synchronous wheel and a synchronous belt. An L-shaped connecting arm 22 is slidably installed in the rectangular groove 20, and the L-shaped connecting arm 22 is threadedly connected to the screw rod 21, and one end of the L-shaped connecting arm 22 is fixed to the trapezoidal extrusion plate 19, and the other end is fixed to the top of the second fixed plate 23.

[0052] Specifically, when the screw 21 is rotated, the L-shaped connecting arm 22 drives the trapezoidal extrusion plate 19 and the second fixed plate 23 to move synchronously. The second fixed plate 23 drives the first gear 16 and the mold box 12 to rotate through the first rack 24. At the same time, the trapezoidal extrusion plate 19 pushes the demolding rod 25 to push the molding material out of the mold box 12.

[0053] Reference Figure 3-Figure 6 A plurality of demoulding rods 25 are slidably installed in the U-shaped support plate 13 below the mold box 12, and the top of the demoulding rod 25 is sealed and extends into the mold box 12. The outer wall of the demoulding rod 25 is sleeved with a first spring 26, and the two ends of the first spring 26 are fixedly connected to the bottom of the U-shaped support plate 13 and the demoulding rod 25 respectively.

[0054] Specifically, when the trapezoidal extrusion plate 19 moves to contact the demoulding rod 25, its inclined surface pushes the demoulding rod 25 to move upward, overcomes the resistance of the first spring 26, pushes the molding material out of the mold box 12, and drops it onto the conveyor belt 29 below.

[0055] Reference Figure 7 A stacking structure is also provided in the cooling box 27 for stacking the molding materials on the conveyor belt 29 onto the frame 34 one by one.

[0056] Reference Figure 7 The stacking structure specifically includes an electric push rod 32 fixedly mounted on the bottom inner wall of the cooling box 27, and a lifting plate 33 is firmly connected to the end of the output shaft of the electric push rod 32. The lifting plate 33 is designed to push the molding material, i.e., the processed carbon fiber heating material, upward from the bottom. In particular, the electric push rod 32 and its lifting plate 33 are both arranged in the space between the two conveyor belts 29 to ensure that there is no interference with the conveyor belts 29 during the pushing process.

[0057] Reference Figure 7 and Figure 8Next, a plurality of trapezoidal slides 35 are slidably passed through the interior of each frame 34. The bottom inclined surfaces of these trapezoidal slides 35 are designed to cooperate with the bottom of the molding material so that when the molding material is lifted, the trapezoidal slides 35 can be smoothly pushed to move outward. In order to realize the reset function of the trapezoidal slides 35, a connecting plate 36 is fixedly connected to the side of each trapezoidal slide 35 away from the electric push rod 32. A first guide rod 37 is slidably passed through each connecting plate 36, and the end of these first guide rods 37 close to the electric push rod 32 is fixedly connected to the adjacent frame 34. Through such a design, the first guide rod 37 not only provides a stable sliding track for the trapezoidal slide 35, but also ensures the linearity of the trapezoidal slide 35 during movement.

[0058] Reference Figure 7 and Figure 8 In order to drive the trapezoidal slide plate 35 to automatically reset to the inside after the molding material is removed, a first tension spring 38 is sleeved on the outer wall of each first guide rod 37. One end of these first tension springs 38 is fixedly connected to the connecting plate 36, and the other end is fixedly connected to the frame 34. Therefore, when the output shaft of the electric push rod 32 pushes the lifting plate 33 to move upward, and then pushes the molding material upward, the bottom of the molding material will contact the inclined surface of the trapezoidal slide plate 35 and push it to move outward. As the molding material continues to move upward, the trapezoidal slide plate 35 will be completely located below the molding material. At this time, the electric push rod 32 stops working, and under the tension of the first tension spring 38, the trapezoidal slide plate 35 will quickly move to the inside and reset, so as to be located below the molding material again to provide support for it. By repeating the above operation, the subsequent molding materials can be gradually stacked together. This stacking method is not only convenient for later handling and storage, but also because the molding material is exposed to the air during the stacking process, it can also be effectively cooled naturally, thereby improving production efficiency.

[0059] Reference Figure 5 Two damping bearings 17 are fixedly installed inside the workbench 1, and the two rotating shafts 8 respectively pass through the two damping bearings 17. Through the effect of the damping bearings 17, the shaking of the rotating shaft 8 during the rotation process can be effectively avoided, thereby improving the stability and reliability of the entire device.

[0060] Specifically, when the mold box 12 is turned over with the cooperation of the first rack 24 and the first gear 16, the mold box 12 and the rotating shaft 8 will remain stationary under the action of the damping bearing 17, thereby preventing the trapezoidal extrusion plate 19 from contacting the demolding rod 25 and pushing the mold box 12 to rotate.

[0061] Reference Figure 7In addition, two trapezoidal guide plates 31 are fixedly installed on the inner wall of the cooling box 27 on one side away from each other. The two trapezoidal guide plates 31 are respectively located on both sides of the two conveyor belts 29, and their function is to regularize the molding materials during transportation so that they can be stacked together more neatly. In particular, the top of the trapezoidal guide plate 31 is designed to be flush with the top of the molding material to ensure that there will be no misalignment or tilting during the stacking process. At the same time, a convex baffle 30 is fixed inside the cooling box 27, and one end of the two trapezoidal guide plates 31 is fixedly connected to one side of the convex baffle 30. The function of this convex baffle 30 is to limit the molding material to prevent it from sliding or shifting during the stacking process.

[0062] Reference Figure 4 and Figure 6 The demoulding rod 25 is designed to slide and extend into the mold box 12, and its top is flush with the bottom inner wall of the mold box 12. This design ensures that the demoulding rod 25 can smoothly and effectively push the molding material out of the mold during the demoulding process without damaging the material.

[0063] Through the above-mentioned specific implementation manner, the production equipment of carbon fiber heating material can realize automated hot pressing molding, cooling and stacking processing, thereby improving production efficiency and product quality.

[0064] Example 2: Reference Figure 10-12 , improved on the basis of Example 1: a placement plate 39 is installed on each side of the cooling box 27, and the top of the placement plate 39 is flush with the top of the trapezoidal guide plate 31. On the top of the placement plate 39, a plurality of slidable push plates 41 and pads 42 are designed. The pads 42 cooperate with the inclined surface of the trapezoidal slide 35 so that when the trapezoidal slide 35 moves, the pads 42 can move toward the middle. The push plates 41 are used to push the plurality of pads 42 one by one onto the top of the molding material. To achieve this function, two push rods 40 are installed on each placement plate 39, and the push rods 40 are slidably connected to the top of the placement plate 39 through a base and fixed on the push plates 41. When the push rods 40 move, they will drive the push plates 41 and the pads 42 to move together. In addition, a second rack 46 is fixed to the bottom of each push rod 40.

[0065] The bottom of each placement plate 39 is rotatably connected to a rotating shaft 43 through a base, and a third gear 52 is fixedly sleeved on the rotating shaft 43, and the gear is meshed with the adjacent second rack 46. A one-way bearing 44 is also provided on the outer wall of the rotating shaft 43, and the inner ring of the one-way bearing 44 is fixedly connected to the rotating shaft 43, and the outer ring is fixed with a second gear 45. Both sides of the cooling box 27 are sealed and slidably penetrated by a trapezoidal transmission rod 47, and the top of the trapezoidal transmission rod 47 is fixed with a third rack 48, which is meshed with the second gear 45. The bottom of the trapezoidal transmission rod 47 is slidably penetrated by a second guide rod 50 through the base, and the two ends of the second guide rod 50 are respectively fixedly connected to the two sides of the cooling box 27, and are sleeved with a second tension spring 49, which is used to drive the trapezoidal transmission rod 47 to move inward and reset.

[0066] Specifically, when the electric push rod 32 drives the lifting plate 33 to move upward, the blocking plates 51 fixed on both sides of the bottom of the lifting plate 33 will contact the inclined surface of the trapezoidal transmission rod 47, thereby driving the trapezoidal transmission rod 47 to move outward. The movement of the trapezoidal transmission rod 47 drives the second gear 45 to rotate through the third rack 48. Due to the locking effect of the one-way bearing 44, the second gear 45 will drive the rotating shaft 43 and the third gear 52 to rotate. The cooperation between the third gear 52 and the second rack 46 drives the push rod 40 and the push plate 41 to move inward, pushing the pad 42 located on the trapezoidal guide plate 31 to the top of the molding material to be stacked. As the lifting plate 33 continues to move upward, when the trapezoidal transmission rod 47 completely contacts the blocking plates 51, the trapezoidal transmission rod 47 and the push plate 41 are both in a stationary state. At this time, the lifting plate 33 pushes the molding material and the pad 42 above it to continue to move upward to complete the stacking. After stacking is completed, the pad 42 is naturally left between two adjacent molding materials to form a gap, which not only accelerates cooling but also facilitates subsequent handling.

[0067] A production process of a carbon fiber heating material production device comprises the following steps:

[0068] S1, put the carbon fiber composite material into the mold box 12, the cylinder 3 pushes the mold plate 4 and the carbon fiber electric heating plate 5 to move down, the carbon fiber electric heating plate 5 starts to heat, the mold plate 4, the carbon fiber electric heating plate 5 and the mold box 12 cooperate to perform hot pressing molding on the material, after molding is completed, the cylinder 3 drives the mold plate 4 and the carbon fiber electric heating plate 5 to reset;

[0069] S2. When the molding material needs to be demolded, one of the screws 21 is driven to rotate by the motor, and the two screws 21 are synchronously rotated through the synchronous wheel and the synchronous belt. The screw 21 drives the second fixed plate 23 and the first rack 24 to move through the L-shaped connecting arm 22. The first rack 24 is engaged with the first gear 16 to drive the rotating shaft 8, the turntable 9, the first fixed plate 11 and the mold box 12 to rotate 180°. At this time, the mold box 12 is turned over, and the screw 21 continues to drive the L-shaped connecting arm 22 and the second fixed plate 23 to move. The connecting arm 22 synchronously drives the trapezoidal extrusion plate 19 to move, and the first rack 24 is now disengaged from the first gear 16. In addition, under the action of the damping bearing 17, the mold box 12 and the rotating shaft 8 remain stationary to prevent the mold box 12 from shaking. As the mold box 12 drives the trapezoidal extrusion plate 19 to move, the inclined surface on one side of the trapezoidal extrusion plate 19 cooperates with the demoulding rod 25 and pushes the demoulding rod 25 to extend into the mold box 12, pushing the blank of the molding material out of the mold box 12 and onto the conveyor belt 29;

[0070] S3, the demoulding molding material is cooled. Since cooling water is contained in the cooling box 27, when the molding material falls on the conveyor belt 29, the cooling water can just submerge the molding material for cooling it. The rotating roller 28 cooperates with the conveyor belt 29 to transport the molding material to one side and align and stack it for easy handling in the later stage. During the movement, the molding material is neatly arranged under the action of the two trapezoidal guide plates 31, and the convex baffle plate 30 limits the molding material. At this time, the output shaft of the electric push rod 32 pushes the lifting plate 33 to move upward, and the lifting plate 33 pushes the molding material upward. When the molding material moves upward, the trapezoidal slide plate 35 moves outward under the action of its inclined surface until the molding material is located above the trapezoidal slide plate 35. The trapezoidal slide plate 35 is reset and located below the molding material under the tension of the first tension spring 38. The trapezoidal slide plate 35 supports the molding material. Repeating the operation can gradually stack the subsequent molding materials, which is not only convenient for later handling, but also the molding materials are exposed to the air after stacking for cooling.

[0071] S4. When the electric push rod 32 drives the lifting plate 33 to move upward, the lifting plate 33 drives the trapezoidal transmission rod 47 to move outward under the action of the inclined surface of the trapezoidal transmission rod 47, and the trapezoidal transmission rod 47 drives the second gear 45 to rotate through the third rack 48. The second gear 45 drives the one-way bearing 44 to rotate. The one-way bearing 44 and the rotating shaft 43 are in a locked state. The one-way bearing 44 drives the third gear 52 to rotate through the rotating shaft 43. The cooperation of the third gear 52 and the second rack 46 drives the push rod 40 and the push plate 41 to move inward, so that the pad 42 located on the trapezoidal guide plate 31 can be moved above the molding material to be stacked, and then the lifting plate 33 pushes the molding material and its When the upper pad 42 moves up, the trapezoidal transmission rod 47 contacts the blocking plate 51, and the trapezoidal transmission rod 47 and the pushing plate 41 are both in a stationary state. After the molding materials are stacked, the pad 42 can form a gap between two adjacent molding materials for ventilation, which not only accelerates cooling but also facilitates later transportation. In addition, after the lifting plate 33 moves down and resets, the trapezoidal transmission rod 47 moves toward the middle under the tension of the second tension spring 49, and the third rack 48 drives the second gear 45 and the one-way bearing 44 to rotate in the opposite direction. The one-way bearing 44 and the pad 42 are in an active state. Therefore, as the trapezoidal transmission rod 47 moves left and right, multiple pads 42 can be gradually moved onto the molding materials to be stacked.

[0072] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric push rod 32, the carbon fiber electric heating plate 5 and the cylinder 3 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
