Description

Technical Field

[0001] The invention belongs to the technical field of 3D printing, and in particular relates to a continuous carbon fiber printer with a fusion device. Background Art

[0002] A continuous carbon fiber printer is a device that uses continuous fiber-reinforced polymer composites to produce lightweight and high-strength composite parts through 3D printing technology. This printer can embed continuous fiber materials during the printing process, significantly improving the structural strength and rigidity of the printed parts, making it have broad application prospects in aerospace, automobile manufacturing, robotics and other fields.

[0003] The Chinese patent with publication number CN105500705A discloses a 3D printer feed fusion connection device. When the material does not need to be replaced, the fusion connection device is closed, the device will not be heated, and the material will naturally pass through the feed conduit without any loss of material. When the material needs to be replaced, the device is turned on and heated, and the new material is inserted immediately after the end of the old material completely enters the feed port, so that it melts and bonds successfully in the heating area.

[0004] However, this technical solution still has at least the following defects: when the device is fusing, the material is melted at the heating device, which may cause adhesion. The use of lubricant to apply to the inner wall of the feed pipe can temporarily delay the occurrence of adhesion, but as the number of uses increases, the effect of the lubricant decreases. If it is not added in time, it will also cause adhesion. In view of this, the present invention is proposed. Summary of the invention

The end of the rocker 403 is rotatably connected to the base plate 201 , and the top of the rocker 403 is rotatably connected to a sleeve 404 .

[0048] like Figure 2 , Figure 3 , Figure 4 , Figure 8 As shown, in a specific embodiment, two fixed plates 202 are fixedly installed at both ends of the top of the base plate 201, a slide bar 203 is fixedly installed between the two fixed plates 202 on the same side, a slider 204 is slidably connected to the two slide bars 203, and both ends of the movable frame 300 are movably sleeved on the two slide bars 203.

The same magnets repel each other. In this setting, the repulsive force of the first magnet 302 and the second magnet 303 causes the movable frame 300 to move immediately when unlocked to prevent it from being locked again.

[0049] like Figure 3-Figure 6 As shown, further, blocks 305 are movably inserted at both ends of the base plate 201, the shape of the movable frame 300 is concave, the top of the block 305 extends to the bottom of the movable frame 300, and a guide slope 304 is provided on one side of the bottom of the movable frame 300, and the guide slope 304 is adapted to the block 305. A bottom plate 306 is fixedly installed between the bottoms of the blocks 305 at both ends, and two positioning rods 307 are movably inserted on the bottom plate 306, and the two ends of the positioning rod 307 are respectively fixedly installed on the top of the arm 102 and the bottom of the base plate 201, and a first spring 308 is movably sleeved on the positioning rod 307, and the two ends of the first spring 308 are respectively fixedly installed on the bottom of the bottom plate 306 and the top of the arm 102, and the first spring 308 is always in a compressed state. In this configuration, after welding is completed, the movable frame 300 is reset, and the movable frame 300 is offset from the block 305 through the guide slope 304 . At the same time, the bottom plate 306 drives the block 305 to move upward and lock the movable frame 300 under the action of the first spring 308 .

[0050] Example 2

[0051] like Figure 7 , Figure 8As shown, in a specific embodiment, two grooves 400 are provided at the bottom of the base plate 201, and a rotating plate 401 is arranged in the groove 400. A rotating shaft 402 is fixedly installed at one end of the rotating plate 401, and one end of the rotating shaft 402 movably penetrates the base plate 201 and extends to the outside. The two rotating shafts 402 are respectively fixedly connected to the ends of two rocking arms 403. The rotating plate 401 and the rocking arms 403 connected thereto are in the same horizontal orientation, and the rotating plate 401 is located on the top of the bottom plate 306. In this configuration, when the material strip breaks, the sleeve 404 loses support, and at this time the rocking arm 403 rotates under the action of gravity, and drives the rotating plate 401 to rotate through the rotating shaft 402, and the rotating plate 401 presses against the bottom plate 306 to move it downward.

[0052] like Figure 6 , Fig. 9 , Fig.11 As shown, further, two fixed blocks 500 are fixedly installed at the bottom of the base plate 201 near the rocker 403, a sliding shaft 501 is fixedly installed between the two fixed blocks 500, two supporting blocks 503 are movably sleeved on the sliding shaft 501, and second springs 502 are movably sleeved at both ends of the sliding shaft 501, and the two ends of each second spring 502 are respectively fixedly installed between the adjacent fixed blocks 500 and the supporting blocks 503, and the second springs 502 are always in a compressed state. In this setting, the elastic force of the second spring 502 is used to drive the supporting blocks 503 to move.

[0053] like Figure 9-10 As shown, further, a notch is provided on the side of the substrate 201 close to the rocker 403, a fixing rod 506 is fixedly installed in the notch, two iron blocks 505 are slidably connected to the fixing rod 506, the bottom of the iron block 505 is fixedly connected to the top of the support block 503, a mounting block 512 is fixedly installed on one side of the end of the rocker 403, the mounting block 512 is perpendicular to the direction of the rocker 403, and a third magnet 513 is embedded and connected at the end of the mounting block 512 close to the side of the substrate 201, and the third magnet 513 is adapted to the iron block 505. In this configuration, the elastic force of the second spring 502 drives the support block 503 to move, and the support block 503 drives the iron block 505 to move, rotating the rocker 403 to make it in a vertical state, at which time the mounting block 512 is in a horizontal state, and at the same time the third magnet 513 and the iron block 505 are attracted to each other, so that the rocker 403 remains stationary.

[0054] Example 3

[0055] like Figure 9-11As shown, in a specific embodiment, a positioning block 507 is fixedly installed in the middle of the fixed rod 506, and a top rod 508 is slidably connected to one side of the positioning block 507. The two ends of the top rod 508 are respectively aligned with the bottom of the support block 503. A right-angle groove 504 is provided on one side of the support block 503. An extension block 511 is fixedly installed on one side of the end of the two rocking arms 403. A telescopic rod 510 is rotatably connected between the two extension blocks 511. A third spring 509 is fixedly installed at the bottom of the telescopic rod 510, and the other end of the third spring 509 is fixedly connected to the middle of the top rod 508. In this setting, when the rocking arm 403 rotates, it drives the extension block 511 connected thereto, and the extension block 511 pulls one end of the telescopic rod 510 and makes it rise. At this time, the middle part of the telescopic rod 510 rises, and drives the top rod 508 to rise through the third spring 509. The top rod 508 rises and moves to the right-angle groove 504. At this time, the support blocks 503 on both sides lose support.

[0056] like Fig.12 As shown, further, a mounting groove 600 is provided inside the base plate 201, and the mounting groove 600 is provided with two first pull rods 601, one end of the two first pull rods 601 is respectively connected to one side of the two iron blocks 505, and the other ends of the two first pull rods 601 are connected to each other, and the second pull rod 602 is connected to the connection between the two first pull rods 601, and the other end of the second pull rod 602 is installed with a slide plate 603, and the slide plate 603 is connected in a sliding manner in the mounting groove 600, and the other end of the slide plate 603 extends to the outside of the base plate 201. In this setting, when the iron block 505 moves, it drives one end of the two first pull rods 601 to move, and makes the other end move with it, the first pull rod 601 supports the second pull rod 602 to make it move, and the second pull rod 602 drives the slide plate 603 and the copper plate 604 to make them move.

[0057] like Fig.12 , Fig.13 As shown, further, a copper plate 604 is connected through the inside of the slide plate 603, and the copper plate 604 is aligned with both sides of the slide plate 603. Two mounting plates 605 are installed on one side of the substrate 201, and a contact electrode 606 is installed on one side of the mounting plate 605. The contact electrode 606 is aligned with the copper plate 604. An alarm 607 is fixedly installed at the bottom of the two mounting plates 605, and the alarm 607 is electrically connected to the contact electrode 606. In this setting, the second pull rod 602 drives the slide plate 603 and the copper plate 604 to move and extend out of the substrate 201. At this time, the copper plate 604 contacts the contact electrode 606, so that the circuit of the alarm 607 is connected. At this time, the alarm 607 alarms and reminds the staff. The alarm 607 is provided with a switch for independent operation, and the staff turns off the alarm 607 through the switch.

[0058] like Figure 3-Figure 6As shown, further, the base frame 200 is fixedly installed on both sides of the bottom of the base plate 201, and the bottom of the base frame 200 is fixedly installed on the top of the machine arm 102. In this configuration, the base frame 200 is used to fix the base plate 201 on the machine arm 102.

[0059] The implementation principle of a continuous carbon fiber printer with a fusion device in this embodiment is as follows: during normal printing, the material strip enters the print head 104 through the material guide slot 103 for printing, at which time the material strip between the print head 104 and the material guide slot 103 is in a tensioned state, and the sleeve 404 is directly mounted on the material strip;

[0060] When the material strip breaks, the sleeve 404 loses support, and the rocker 403 rotates under the action of gravity, and drives the rotating plate 401 to rotate through the rotating shaft 402. The rotating plate 401 presses against the bottom plate 306 to move it downward, and drives the block 305 to move downward. The block 305 is separated from the movable frame 300. At this time, the movable frame 300 moves under the repulsive force of the first magnet 302 and the second magnet 303, and staggers with the block 305.

[0061] When the rocker 403 rotates, it drives the extension block 511 connected thereto, and the extension block 511 pulls one end of the telescopic rod 510 and makes it rise. At this time, the middle part of the telescopic rod 510 rises, and drives the top rod 508 to rise through the third spring 509. The top rod 508 rises and moves to the right-angle groove 504. At this time, the support blocks 503 on both sides lose their support, and the elastic force of the second spring 502 drives the support block 503 to move, and the support block 503 drives the iron block 505 to move;

[0062] When the iron block 505 moves, it drives one end of the two first pull rods 601 to move, and makes the other end move with it. The first pull rod 601 supports the second pull rod 602 to move it, and the second pull rod 602 drives the slide plate 603 and the copper plate 604 to move and extend out of the substrate 201. At this time, the copper plate 604 contacts the contact electrode 606, so that the circuit of the alarm 607 is connected. At this time, the alarm 607 alarms and reminds the staff;

[0063] After receiving the warning, the staff turns off the alarm switch, rotates the rocker 403 to make it in a vertical state, at which time the mounting block 512 is in a horizontal state, and at the same time the third magnet 513 and the iron block 505 are attracted to each other, so that the rocker 403 remains stationary, and the movable frame 300 and the slider 204 are moved to align with the broken end of the material belt, and the material belt is positioned through the positioning tube 301. At this time, the broken end of the material belt does not contact the positioning tube 301, and the high-temperature flame is sprayed through the nozzle 205 to melt and weld the material belt, so that the broken material belt can be connected, and it will not stick to the positioning tube 301;

[0064] After welding is completed, the movable frame 300 is reset, and the movable frame 300 is staggered with the block 305 through the guide slope 304. At the same time, the bottom plate 306 drives the block 305 to move up and lock the movable frame 300 under the action of the first spring 308.

[0065] Push the slide plate 603 to reset it. The slide plate 603 drives the copper plate 604 to separate from the contact electrode 606, thereby cutting off the power to the alarm 607. At this time, turn on the alarm 607 switch to alarm next time. When the slide plate 603 moves, it drives the iron block 505 to move through the second pull rod 602 and the first pull rod 601. The iron block 505 is offset from the third magnet 513. When the iron block 505 is reset, it drives the support block 503 to reset. At this time, the top rod 508 is again located between the two support blocks 503 and against the two support blocks 503. Resetting the rocker 403 can make it work again.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
