Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber paper processing, in particular to a carbon fiber paper cutting device based on rolling flattening. Background Art

[0002] Carbon fiber paper is a lightweight, high-strength composite material made of carbon fiber and resin matrix, commonly used in aerospace, automobile, sports equipment and other fields. Cutting carbon fiber paper requires special equipment to ensure efficient and accurate cutting process while avoiding damage to the carbon fiber paper.

[0003] When cutting existing carbon fiber paper, in order to avoid burrs during cutting, the carbon fiber paper is usually cut in the form of a blade. In order to prevent the depth of the blade from scratching the conveyor belt, the blade cutting part is set to be hollow, and the conveyor belts on both sides are placed separately. The blade moves horizontally to cut the carbon fiber paper. After the cutting is completed, there is a certain distance between the conveyor belts on both sides. At this time, when the cutting device is applied to the case where it cannot move longitudinally, if the blade wants to cut the carbon fiber paper that has been cut on one side again longitudinally, it needs to be manually picked up. When it is transmitted through the conveyor belt, the cut edge of the carbon fiber paper is lower than the conveyor belt under the action of gravity. When it is transmitted, the carbon fiber paper will be blocked by the conveyor belt on the other side, thereby affecting the progress of the transmission and the efficiency of the cutting. Summary of the invention

[0004] The object of the present invention is to provide a carbon fiber paper cutting device based on rolling flattening to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention aims to provide a carbon fiber paper cutting device based on rolling flattening, including a table body and a cutting device, wherein a conveyor belt is symmetrically arranged inside the table body, and a flip plate rotatably connected to the conveyor belt is arranged between the conveyor belts on both sides, and a rolling wheel for flattening the carbon fiber paper is arranged above the flip plate, and an ejection part arranged below includes a hydraulic rod and a vertical ejector rod, wherein the hydraulic rod is fixed on the inner wall of the table body and connected to a plurality of vertical ejector rods fixedly connected to the bottom of the arc-shaped top plate through a cross plate, and the vertical ejector rod is ejected upward, and the arc-shaped top plate between the flip plates on both sides is flipped outward, so that the position of cutting the carbon fiber paper is higher than the height of the carbon fiber paper on the conveyor belt;

[0006] During the process of the arc-shaped top plate being pushed upward, the flip plate will also squeeze the pushing portion at the end of the arc-shaped top plate, and with the assistance of the pushing portion, the flip roller embedded in the arc-shaped top plate will rotate to transport the cut carbon fiber paper to the conveyor belt on the other side, so that the carbon fiber paper flips over the arc-shaped top plate.

[0007] As a further improvement of the present technical solution, the ejection part also includes a lower pressure plate fixedly connected to the horizontal plate. When the lower pressure plate moves downward, connecting rods are fixedly connected to both sides of the rolling wheels. The lower pressure plate exerts downward pressure on the connecting rods and flattens the carbon fiber paper during the transverse movement of the conveyor belt.

[0008] As a further improvement of the technical solution, a baffle provided at the bottom of the flip plate is fixedly connected to the platform body, and the baffle is used to limit the flip plate from flipping counterclockwise, so that the rolling wheel cooperates with the flip plate to flatten the carbon fiber paper.

[0009] As a further improvement of the present technical solution, the ring at the end of the rolling wheel is sleeved on the auxiliary rod and slidably connected to the auxiliary rod. The protrusion provided on the inner wall of the ring abuts against the groove provided on the auxiliary rod to limit the rotation of the rolling wheel. The vertical rod to which the end of the auxiliary rod is slidably connected abuts against the first spring. The first spring is sleeved on the vertical rod, and the bottom of the first spring is fixed to the platform.

[0010] As a further improvement of the present technical solution, the pushing part includes an oblique push rod and an auxiliary push rod. The oblique push rod slides along the arc groove opened at the end of the flip plate, and the oblique push rod is slidably connected to the oblique rods extending on both sides of the arc top plate. One end of the oblique push rod located inside the arc top plate is fixedly connected to the auxiliary push rod. When the arc top plate moves up, the flip plate forms an oblique upward thrust on the oblique push rod.

[0011] As a further improvement of the present technical solution, the pushing part also includes a rack that meshes with a gear, blocks symmetrically provided on both sides of the rack are fitted with an auxiliary push rod, and the rack is slidably connected to the arc-shaped top plate, and the gear is coaxially connected to the flip roller. The auxiliary push rod pushes the block and the rack to one side, rotates the gear connected to the arc-shaped top plate, and cooperates with the conveyor belt on one side to make the cut edge of the carbon fiber paper fall onto the conveyor belt on the other side.

[0012] As a further improvement of the technical solution, the auxiliary push rod is in contact with the reverse push rod when moving, and a fourth spring and an auxiliary ring are mounted on the sliding rod fixedly connected to the back of the reverse push rod. The auxiliary ring is against the fourth spring and fixed to the arc-shaped top plate.

[0013] As a further improvement of the present technical solution, the flip plate is provided with a plurality of air holes at the edge close to the cutting edge of the carbon fiber paper, and the air holes are connected to the top of the air storage tank arranged between the hydraulic rods on both sides through soft air pipes. The downward movement of the hydraulic rod drives the piston rod fixedly connected to the piston plate to move downward, and a second spring is sleeved on the piston rod, so that the piston plate inhales air through the air pipe, forming a negative pressure area in the air hole to adsorb the carbon fiber paper.

[0014] As a further improvement of the technical solution, the piston plate moves downward to compress the air below the piston plate. When the hydraulic rod releases the downward pressure on the cross plate, the second spring pushes the piston plate upward in the opposite direction, so that the air hole changes from a negative pressure area to a high pressure area, blowing the carbon fiber paper upward, reducing the friction between the carbon fiber paper and the arc-shaped top plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the carbon fiber paper cutting device based on rolling flattening, after the carbon fiber paper is cut, the hydraulic rod is released, and under the action of the second spring and the pressure inside the piston chamber, the arc-shaped top plate is pushed upward in the opposite direction, so that the arc-shaped top plate drives the flip plates on both sides to rotate clockwise, thereby raising the height of the cut portion of the carbon fiber paper, so that when the cut carbon fiber paper is transported by the conveyor belt on one side, the cut portion of the carbon fiber paper can smoothly pass over the arc-shaped top plate on the other side and fall onto the conveyor belt on the other side, preventing the cut portion from being blocked, so as to facilitate the carbon fiber paper to be cut again, thereby improving the cutting efficiency.

[0017] 2. In the carbon fiber paper cutting device based on rolling flattening, the oblique push rod is squeezed with the arc-shaped top plate on one side by the upward movement of the arc-shaped top plate. Under the push of the reaction force, the oblique push rod pushes the auxiliary push rod to move the block and the rack to one side, and the rack drives the gear and the flip roller to rotate counterclockwise, thereby reducing the friction between the carbon fiber paper and the arc-shaped top plate, so that the carbon fiber paper can be smoothly transported to the conveyor belt on the other side.

[0018] 3. In the carbon fiber paper cutting device based on rolling flattening, the piston plate moves downward to form a negative pressure zone at the joint between the air hole and the carbon fiber paper, which can ensure that the carbon fiber paper is in contact with the flip plate, and cooperate with the downward pressure of the lower pressure plate on the rolling wheel to prevent the carbon fiber paper from deviating during the cutting process of the cutting device. Secondly, when the piston plate is released, the air hole is transformed from a negative pressure zone to a high pressure zone. Under the action of pressure, a gap is left between the carbon fiber paper and the inclined flip plate, thereby reducing the friction between the carbon fiber paper and the flip plate, so that the carbon fiber paper can smoothly pass over the flip plate on the other side for the next cutting.

[0035] When cutting existing carbon fiber paper, in order to avoid burrs during cutting, the carbon fiber paper is usually cut in the form of a blade. In order to prevent the depth of the blade from scratching the conveyor belt, the blade cutting part is set to be hollow, and the conveyor belts on both sides are placed separately. The blade moves horizontally to cut the carbon fiber paper. After the cutting is completed, there is a certain distance between the conveyor belts on both sides. At this time, when the cutting device is applied to the case where it cannot move longitudinally, if the blade wants to cut the carbon fiber paper that has been cut on one side again longitudinally, it needs to be manually picked up. When it is transmitted through the conveyor belt, the cut edge of the carbon fiber paper is lower than the conveyor belt under the action of gravity. When it is transmitted, the carbon fiber paper will be blocked by the conveyor belt on the other side, thereby affecting the progress of the transmission and the efficiency of the cutting.

[0036] Example

[0037] Since the cut carbon fiber paper needs to be manually picked up and placed, this will reduce the efficiency of the entire cutting. For this reason, the present invention provides a carbon fiber paper cutting device based on rolling flattening, so that after the carbon fiber paper is cut, the cut portion of the carbon fiber paper is lifted upward, so that the carbon fiber paper can slide along the inclined surface during transportation, and thus smoothly fall onto the conveyor belt 102 on the other side, so as to be cut again, thereby improving the cutting efficiency.

[0038] like Figure 1 and Figure 2 As shown, a carbon fiber paper cutting device based on rolling flattening is provided, including a table 100 and a cutting device 101. A conveyor belt 102 is symmetrically arranged inside the table 100. Similar to the cutting equipment in the prior art, the cutting device 101 is mounted above the table 100, and the cutting device 101 can move back and forth laterally on the table 100. During the movement of the cutting device 101, the shell connected to the blade and the connecting rod fixedly connected to the rolling wheels 103 on both sides are abutted against each other, thereby pushing the rolling wheels 103 to move on the flip plate 300.

[0039] It should be noted that: the above horizontal Figure 3 For example, the position of the hydraulic rod 201 is the left side, and the other side is the right side, and movement in the left and right directions is lateral movement.

[0040] A flip plate 300 rotatably connected to the conveyor belts 102 is arranged between the conveyor belts 102 on both sides, and a rolling wheel 103 for flattening the carbon fiber paper is arranged above the flip plate 300 to provide support for the carbon fiber paper before cutting. As the cutting device 101 moves, the cutting device 101 abuts against the rolling wheels 103 on both sides, and the rolling wheels 103 on both sides flatten the two sides of the carbon fiber paper cutting position. Then, the ejection part 200 arranged below the flip plate 300 includes a hydraulic rod 201 and a vertical ejector rod 202. The hydraulic rod 201 is fixed on the inner wall of the platform 100 and is connected to a plurality of vertical ejector rods 202 fixedly connected to the bottom of the arc-shaped ejector plate 203 through a cross plate. The vertical ejector rod 202 ejects upward, and the arc-shaped ejector plate 203 between the flip plates 300 on both sides flips outward, so that the position of the carbon fiber paper cutting is higher than the height of the carbon fiber paper on the conveyor belt 102, thereby realizing the function of lifting the carbon fiber paper.

[0041] Therefore, based on the above structure, Figure 4 The structure of the ejection part 200 is further disclosed. The ejection part 200 also includes a lower pressure plate 204 fixedly connected to the cross plate. When the hydraulic rod 201 pushes the cross bar and the lower pressure plate 204 to move downward, the two sides of the rolling wheels 103 above the lower pressure plate 204 are fixedly connected to the connecting rods. The lower pressure plate 204 exerts downward pressure on the connecting rods and flattens the carbon fiber paper during the transverse movement of the conveyor belt 102, thereby ensuring the cutting accuracy and preventing the cutting from being offset.

[0042] The specific flattening process of the rolling wheel 103 is as follows:

[0043] pass Figure 4 And cooperate Figure 6 It is shown that the ring at the end of the rolling wheel 103 is sleeved on the auxiliary rod 104, the ring is slidably connected to the auxiliary rod 104, and the protrusion provided on the inner wall of the ring is abutted against the groove opened on the auxiliary rod 104, wherein the purpose of providing the groove and the protrusion is to prevent the ring from sliding on the auxiliary rod 104 and limit the rotation of the rolling wheel 103 on the auxiliary rod 104.

[0044] In order to ensure that the rolling wheel 103 can be separated from the carbon fiber paper after the cutting is completed, the end of the auxiliary rod 104 is sleeved on the vertical rod 106 which is slidably connected, and the first spring 105 sleeved on the vertical rod 106 is against the end of the auxiliary rod 104, and the bottom of the first spring 105 is fixed to the platform 100, so that the connecting rod and the rolling wheel 103 squeezed by the lower pressure plate 204 can be pushed away from the carbon fiber paper by the elastic force of the first spring 105 when the lower pressure plate 204 releases the downward pressure, so that the carbon fiber paper can be transported after the cutting is completed in the later stage.

[0045] Furthermore, when the hydraulic rod 201 pushes the horizontal plate downward, in order to make the carbon fiber paper close to the flip plate 300, the hydraulic rod 201 also pushes the piston rod and the piston plate 206 downward. Figure 5 and Figure 7 As shown, the flip plate 300 is provided with a plurality of air holes 311 at the edge close to the cutting of the carbon fiber paper, and the air holes 311 are connected to the top of the gas tank 205 arranged between the hydraulic rods 201 on both sides through soft air pipes. As the hydraulic rod 201 drives the piston rod fixedly connected to the piston plate 206 to move downward, the piston plate 206 squeezes the second spring 207 sleeved on the piston rod, and the air is drawn into the gas tank 205 through the air pipe and the air holes 311 above the piston plate 206, so that a negative pressure area is formed at the joint of the air holes 311 and the carbon fiber paper, thereby adsorbing the carbon fiber paper, so that the carbon fiber paper can be more closely fitted to the flip plate 300, and the carbon fiber paper can be prevented from deviating during cutting.

[0046] At the same time, the downward movement of the piston plate 206 will also compress the air below the piston plate 206. When the hydraulic rod 201 instantly releases the downward pressure on the cross plate, the compressed gas and the elastic force of the second spring 207 push the piston plate 206 upward in the opposite direction, and the original air hole 311 changes from a negative pressure area to a high pressure area, and then the carbon fiber paper is blown upward under the action of pressure, so as to reduce the friction between the carbon fiber paper and the arc-shaped top plate 203 during transportation.

[0047] In addition, the downward movement of the horizontal plate will also drive the arc-shaped top plate 203 to move downward, the purpose of which is: by moving the arc-shaped top plate 203 downward, the arc-shaped top plate 203 is moved away from the blade in the cutting device 101 to prevent the arc-shaped top plate 203 from being scratched by the flip roller 107 embedded in the arc-shaped top plate 203, thereby causing the edge of the carbon fiber paper after cutting to collide with the dent formed on the roller 107, affecting the transportation of the carbon fiber paper.

[0048] It should be additionally explained that: when the carbon fiber paper is not cut, the baffle 310 provided at the bottom of the flip plate 300 is fixedly connected to the platform 100, and the baffle 310 is used to limit the counterclockwise flipping of the flip plate 300 and provide support for the flip plate 300, so that the rolling wheel 103 cooperates with the flip plate 300 to flatten the carbon fiber paper.

[0049] Return to Figure 4 As the cutting proceeds, the carbon fiber paper is gradually cut until it is divided into two parts. When the carbon fiber paper is completely cut, the hydraulic rod 201 releases the downward pressure on the horizontal plate. At this time, the horizontal plate and the vertical top rod 202 will push the arc top plate 203 upward in the opposite direction.

[0050] Next, the cut carbon fiber paper is transported. At this time, Figure 8 and Fig. 9As shown, the arc-shaped top plate 203 moves upward, and the pushing part 400 and the flip roller 107 move upward synchronously. The pushing part 400 squeezes the flip plates 300 on both sides, and the flip plates 300 flip counterclockwise. With the assistance of the arc-shaped groove of the flip plate 300, an opposite force is formed on the pushing part 400, and the flip roller 107 is driven to rotate by the pushing part 400. The rotating flip roller 107 cooperates with the conveyor belt 102 to transport the cut carbon fiber paper to the conveyor belt 102 on the other side, so that the cut edge of the carbon fiber paper flips over the arc-shaped top plate 203 on the other side, so as to realize the transportation of the cut carbon fiber paper, thereby reducing the manual picking steps and helping to improve the cutting efficiency.

[0051] The counterclockwise direction mentioned above should be Figure 8 For example, the direction in which the flip roller 107 rotates at this time is counterclockwise.

[0052] As described above, the specific structure of the pushing part 400 is disclosed. In this embodiment, the pushing part 400 includes an inclined push rod 401 and an auxiliary push rod 402. During the upward movement of the curved top plate 203, the inclined push rod 401 slides along the curved groove opened at the end of the flip plate 300, and the inclined push rod 401 is slidably connected to the inclined rods extending on both sides of the end of the curved top plate 203, and the inclined rod slides in the curved groove. In this way, the auxiliary push rod 402 is fixedly connected to the end of the inclined push rod 401 located inside the curved top plate 203 to form a thrust on the auxiliary push rod 402, so that the auxiliary push rod 402 pushes the blocks arranged on both sides of the rack 403 to move.

[0053] As the rack 403 moves, the rack 403 drives the meshing gear 108 to rotate. Because the gear 108 and the flip roller 107 are coaxially connected, the rotating flip roller 107 will transport the cut portion of the carbon fiber paper to the opposite side, so that the carbon fiber paper is lifted and passes over the arc-shaped top plate 203 on the opposite side and falls onto the conveyor belt 102 on the opposite side (such as Figure 2 As shown), in order to realize the transportation of the cut carbon fiber paper, the above-mentioned problem of manual transportation is solved, and it is easy to use.

[0054] When the auxiliary push rod 402 moves, the auxiliary push rod 402 will also push the reverse push rod 109 and the slide rod to move, because the slide rod fixedly connected to the back of the reverse push rod 109 is sleeved with a fourth spring 110 and an auxiliary ring, and the auxiliary ring is against the fourth spring 110 and fixed to the arc-shaped top plate 203. Therefore, when the cut carbon fiber paper is transported to the other side, the arc-shaped top plate 203 returns to its initial state. Under the elastic action of the fourth spring 110, the fourth spring 110 pushes the reverse push rod 109 and the auxiliary push rod 402 in the reverse direction to return to their original positions, so as to cut the carbon fiber paper again.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
