Technical Field
[0001] This utility model relates to the field of 3D printer component technology, specifically to an industrial-grade highly flexible 3D printer flat filament. Background Technology
[0002] 3D printers, also known as three-dimensional printers, are a type of rapid prototyping equipment. In order to power 3D printers, a power cable is usually required.
[0003] Existing 3D printer power cables are typically round wires with large diameters, taking up a lot of space. They also have low power, low current, and low integration, requiring the use of multiple wires simultaneously, which can easily lead to confusion and make them difficult to distinguish and organize. To solve these technical problems, we have designed an industrial-grade, highly flexible flat 3D printer cable. Utility Model Content
[0004] The purpose of this invention is to provide an industrial-grade, highly flexible flat 3D printer filament that has the advantages of being space-saving and capable of multi-filament aggregation. This solves the problems of existing 3D printer power cables, which are usually round, have large diameters, take up a lot of space, have low power and current, low wire bundle integration, require the use of multiple wire bundles at the same time, and are prone to confusion, making them difficult to distinguish and organize.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an industrial-grade high-flexibility 3D printer flat filament, comprising a flat filament body, a protective sleeve disposed in the inner cavity of the flat filament body, a conductive wire disposed in the inner cavity of the protective sleeve, a first reinforcing wire passing through the front side of the flat filament body, a second reinforcing wire disposed in the inner cavity of the protective sleeve, a fixing component disposed on the surface of the flat filament body, the flat filament body including a base sleeve, and the protective sleeve including a flame-retardant layer.
[0006] Preferably, a reinforcing layer is bonded to the surface of the base sleeve, a tensile layer is bonded to the surface of the reinforcing layer, and a wear-resistant layer is bonded to the surface of the tensile layer.
[0007] Preferably, the wear-resistant layer is made of nylon, the tensile layer is made of polypropylene, and the reinforcing layer is made of polycarbonate.
[0008] Preferably, an insulating layer is bonded to the surface of the flame-retardant layer, and a buffer layer is bonded to the surface of the insulating layer.
[0009] Preferably, the flame-retardant layer is made of glass fiber, the insulating layer is made of polyimide, and the buffer layer is made of foamed polyethylene.
[0010] Preferably, the fixing component includes a movable sleeve that is fitted onto the surface of the flat wire body. The top of the movable sleeve is connected to a mounting shell. A spring is welded to the top of the inner cavity of the mounting shell, and a friction block is welded to the bottom of the spring. A pull rod is provided through the top of the mounting shell, and the bottom of the pull rod is connected to the friction block by a bolt. A Velcro strap is adhered to the bottom of the movable sleeve.
[0011] Preferably, the top of the pull rod is bolted to a handle, and the surface of the pull rod is slidably connected to the mounting housing.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention uses a pull rod to move the friction block up and down, separating the bottom of the friction block from the flat yarn body. Then, pulling the movable sleeve moves the mounting shell and the Velcro strap back and forth to adjust the position of the movable sleeve. After adjustment, the movable sleeve is positioned by securing it with the Velcro strap. After the pull rod is released, the friction block re-contacts the flat yarn body under the action of the spring force. The movable sleeve is positioned by the friction between the bottom of the friction block and the flat yarn body, thus preventing the flat yarn body from shaking randomly.
[0014] This invention reinforces the flat wire body with a first reinforcing wire and a second reinforcing wire, effectively preventing the flat wire body from being pulled apart. The wear-resistant layer provides wear resistance, effectively preventing the surface of the flat wire body from being worn. The tensile layer and the reinforcing layer strengthen the flat wire body, effectively preventing the flat wire body from being pulled apart by external force. The insulation layer provides insulation, effectively preventing leakage of electricity inside the protective sleeve. The flame-retardant layer provides flame retardancy, effectively preventing spontaneous combustion inside the flat wire body. Attached Figure Description

[0020] Please see Figures 1-4 An industrial-grade high-flexibility 3D printer flat filament includes a flat filament body 1, a protective sleeve 2 disposed in the inner cavity of the flat filament body 1, a conductive wire 4 disposed in the inner cavity of the protective sleeve 2, a first reinforcing wire 3 passing through the front side of the flat filament body 1, a second reinforcing wire 5 disposed in the inner cavity of the protective sleeve 2, a fixing component 19 disposed on the surface of the flat filament body 1, the flat filament body 1 including a base sleeve 12, and the protective sleeve 2 including a flame-retardant layer 16.
[0021] Please see Figure 1 and Figure 2 The surface of the base sleeve 12 is bonded with a reinforcing layer 13, and the surface of the reinforcing layer 13 is bonded with a tensile layer 14. By setting the tensile layer 14, it can play a tensile role and effectively prevent the flat wire body 1 from being pulled apart. The surface of the tensile layer 14 is bonded with a wear-resistant layer 15.
[0022] Please see Figure 2 The wear-resistant layer 15 is made of nylon, the tensile layer 14 is made of polypropylene, and the reinforcing layer 13 is made of polycarbonate. By setting the reinforcing layer 13, the strength of the flat wire body 1 can be enhanced, and the flat wire body 1 can be effectively prevented from being damaged by external forces.
[0023] Please see Figure 1 and Figure 3 An insulating layer 17 is bonded to the surface of the flame-retardant layer 16, and a buffer layer 18 is bonded to the surface of the insulating layer 17. By setting the flame-retardant layer 16, it can play a flame-retardant role and effectively prevent the conductive wire 4 inside the protective sleeve 2 from leaking electricity and catching fire.
[0024] Please see Figure 2 The flame retardant layer 16 is made of glass fiber, the insulation layer 17 is made of polyimide, and the buffer layer 18 is made of foamed polyethylene. By setting the buffer layer 18, it can play an impact-resistant role and effectively prevent the first reinforcing wire 3 from being crushed.
[0025] Please see Figure 1 and Figure 3The fixing component 19 includes a movable sleeve 6, which is fitted onto the surface of the flat wire body 1. The top of the movable sleeve 6 is connected to a mounting shell 7. A spring 9 is welded to the top of the inner cavity of the mounting shell 7. By setting the spring 9, it is easy to provide elastic force to the friction block 10, and it is easy to make the bottom of the friction block 10 in close contact with the flat wire body 1. The friction block 10 is welded to the bottom of the spring 9. A pull rod 11 is provided through the top of the mounting shell 7. The bottom of the pull rod 11 is connected to the friction block 10 by bolts. A Velcro strap 8 is glued to the bottom of the movable sleeve 6.
[0026] Please see Figure 1 A handle is bolted to the top of the pull rod 11. The surface of the pull rod 11 is slidably connected to the mounting shell 7. The handle makes it easy for workers to grip the pull rod 11 and pull it.
[0027] In use, pulling the lever 11 causes the friction block 10 to move up and down, separating the bottom of the friction block 10 from the flat yarn body 1. Then, pulling the movable sleeve 6 causes the mounting shell 7 and the Velcro strap 8 to move back and forth, adjusting the position of the movable sleeve 6. After adjustment, the Velcro strap 8 is used to secure the movable sleeve 6 in place. Releasing the lever 11 allows the friction block 10 to re-engage with the flat yarn body 1 under the force of the spring 9. The friction between the bottom of the friction block 10 and the flat yarn body 1 positions the movable sleeve 6, thus preventing the flat yarn body 1 from being positioned. The flat wire body 1 shakes erratically, and the first reinforcing wire 3 and the second reinforcing wire 5 reinforce the flat wire body 1, effectively preventing the flat wire body 1 from being pulled apart. The wear-resistant layer 15 provides wear resistance and effectively prevents the surface of the flat wire body 1 from being worn. The tensile layer 14 and the reinforcing layer 13 strengthen the flat wire body 1 and effectively prevent the flat wire body 1 from being pulled apart by external force. The insulation layer 17 provides insulation and effectively prevents leakage of electricity inside the protective sleeve 2. The flame-retardant layer 16 provides flame retardancy and effectively prevents spontaneous combustion inside the flat wire body 1.
[0028] In summary, this industrial-grade high-flexibility 3D printer flat cable, through its tensile layer 14, wear-resistant layer 15, flame-retardant layer 16, insulation layer 17, buffer layer 18, and fixing component 19, solves the problems of existing 3D printer power cables, which are typically round, have large diameters, take up space, have low power and current, low cable bundle integration, require the use of multiple cable bundles simultaneously, and are prone to confusion, difficulty in distinguishing and organizing them.
