Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a 3D printing wire feeding and clamping device for orthotics. Background Art

[0002] Before the 3D printer starts running, it will find a wire head from the wire reel, and then feed the wire head between the gear and the roller at the wire inlet of the 3D printer. The gear will then rotate to drive the wire to move for wire feeding, and the roller will rotate accordingly. The head of the wire can then be sent to the print nozzle of the 3D printer.

[0003] However, after long-term use, the gears are prone to excessive wear, and the friction between the gears and the wire will be weakened, affecting the normal feeding of the wire. Therefore, the gears need to be replaced regularly, but the operation of replacing the gears is cumbersome and inconvenient. At the same time, in the prior art, it is not convenient to feed 3D printing wires of different thicknesses between the gears and the rollers.

[0004] To this end, a wire feeding and clamping device for 3D printing of orthotics is proposed. Summary of the invention

[0007] A plate body is hinged on one side of the upper surface of the support frame, a transmission shaft is rotatably connected to the support frame, a gear is installed on the outer side of the transmission shaft, a fixing bolt is installed on the top end of the transmission shaft, and the fixing bolt is rotatably connected to the plate body.

[0008] Preferably, the top end of the transmission shaft begins to have an internal thread, and the fixing bolt is adapted to the internal thread.

[0009] Preferably, limiting frames are symmetrically installed on both sides of the lower surface of the shell, and a slide plate is slidably connected inside the limiting frames.

[0010] Preferably, a motor is mounted on the slide plate, a through slot is formed on the lower surface of the shell, and an output shaft of the motor passes through the through slot and is connected to the bottom end of the transmission shaft.

[0011] Preferably, one side of the support frame is rotatably connected to a threaded rod, and the threaded rod is threadedly connected to one side of the shell.

[0012] Preferably, material openings are symmetrically provided on both sides of the shell.

[0013] Preferably, an arc-shaped limiting plate is installed on the outer side of the rubber roller.

[0014] Compared with the prior art, the beneficial effects of the utility model are: the gears can be installed and disassembled more conveniently and quickly through the liftable plate, thereby improving the efficiency of gear replacement; at the same time, in the process of adjusting the distance between the gear and the rubber roller, the motor slides at the bottom of the shell, further limiting the position of the motor and avoiding the occurrence of large vibrations of the equipment due to the operation of the motor.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1-4 , the utility model provides a technical solution: a 3D printing wire feeding clamping device for orthotics, comprising a shell 1, a rubber roller 3 is installed on one side of the shell 1, and a support frame 5 is slidably connected to the other side of the shell 1;

[0022] A plate body 6 is hinged on one side of the upper surface of the support frame 5, and a transmission shaft 14 is rotatably connected to the support frame 5 through a bearing. A gear 13 is installed on the outer side of the transmission shaft 14, and a fixing bolt 7 is installed on the top of the transmission shaft 14. The fixing bolt 7 is rotatably connected to the plate body 6 through a bearing.

[0023] like Figure 3 and Figure 4As shown: the top end of the transmission shaft 14 begins to have an internal thread 15, and the fixing bolt 7 is adapted to the internal thread 15; through the above arrangement, the fixing bolt 7 can be fixed together with the transmission shaft 14, thereby fixing the position of the gear 13.

[0024] like Figure 2 As shown: limiting frames 9 are symmetrically installed on both sides of the lower surface of the shell 1, and the interior of the limiting frame 9 is slidably connected with a slide plate 10; through the above arrangement, the position of the motor 11 can be limited, so that the motor 11 can be moved more conveniently.

[0025] like Figure 2 As shown: a motor 11 is installed on the skateboard 10, a through slot 12 is opened on the lower surface of the shell 1, and the output shaft of the motor 11 passes through the through slot 12 and is connected to the bottom end of the transmission shaft 14; through the above arrangement, the motor 11 drives the transmission shaft 14 to rotate, thereby causing the gear 13 to rotate.

[0026] like Figure 2 and Figure 3 As shown: one side of the support frame 5 is rotatably connected to a threaded rod 8, and the threaded rod 8 is threadedly connected to one side of the housing 1; through the above arrangement, the rotation of the threaded rod 8 can make the support frame 5 move inside the housing 1, thereby adjusting the position of the gear 13.

[0027] like Figure 1 and Figure 2 As shown: the housing 1 is symmetrically provided with feed openings 4 on both sides; through the above arrangement, the wire passes through the openings, which can facilitate the feeding of the wire.

[0028] like Figure 1 As shown: an arc-shaped limiting plate 2 is installed on the outer side of the rubber roller 3; through the above arrangement, the position of the rubber roller 3 is restricted, thereby avoiding the situation in which the rubber roller 3 is tilted and the wire cannot be fed.

[0029] Working principle: When the gear 13 needs to be replaced, first remove the fixing bolt 7 from the end of the transmission shaft 14, then lift the plate body 6, and remove the gear 13 from the transmission shaft 14, then replace the new gear 13 and put down the plate body 6, and fix the position of the plate body 6 and the gear 13 by the fixing bolt 7.

[0030] Then, according to the size of the wire, the distance between the gear 13 and the rubber roller 3 is adjusted, and the support frame 5 is moved inside the shell 1 by rotating the threaded rod 8. At the same time, the motor 11 will follow the transmission shaft 14. The limit frame 9 and the slide plate 10 can make the motor 11 move more conveniently, and the position of the motor 11 can also be limited, thereby improving the stability of the motor 11 and avoiding the occurrence of large vibrations of the equipment due to the operation of the motor 11.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
