It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0030] In one embodiment of the present invention, see Figure 1 and Figure 2 The light-curing 3D printing feeding device comprises an installation box 1, and openings are provided on both sides of the installation box 1. A rotating rod 7 is symmetrically and rotatably provided inside the installation box 1. The rotating rod 7 passes through one end of the installation box 1 and is connected by a transmission component. A rotating disk 8 is symmetrically provided on the rotating rod 7 located on the inner side of the installation box 1. A feeding component for conveying a wire body 9 is provided on the side of the rotating disk 8 close to each other. An extrusion component abutting against the wire body 9 is provided on the top of the inner side of the installation box 1.

[0031] In this embodiment, the transmission component feeds the wire body 9 stably by cooperating with the feeding component, which can effectively prevent the wire body 9 from slipping during the feeding process. The extrusion component facilitates better contact between the feeding component and the wire body 9, thereby improving the movement stability of the wire body 9, and has the effects of stable feeding, safety and anti-slip, simple and reliable structure, convenient operation, and simple and practical use.

[0032] In one embodiment of the present invention, see Figure 1The transmission assembly includes a driving wheel 4 and a driven wheel 6 respectively arranged on two rotating rods 7 passing through one end of the installation box 1, a transmission belt 5 is connected between the driving wheel 4 and the driven wheel 6, a mounting seat 2 is provided on the outside of the installation box 1, and a rotating motor 3 connected to the driving wheel 4 is installed on the mounting seat 2.

[0033] In this embodiment, the rotating motor 3 drives the driving wheel 4 to rotate, and the driving wheel 4 drives the connected rotating rod 7 to rotate synchronously. At the same time, the driving wheel 4 drives the driven wheel 6 to rotate synchronously through the transmission belt 5, and the driven wheel 6 drives the connected rotating rod 7 to rotate synchronously, so that the synchronous rotation of the two rotating rods 7 can be achieved, which is convenient for the stable feeding of the wire body 9.

[0034] In one embodiment of the present invention, see Figure 1 , Figure 2 and Figure 3 and Figure 4 The feeding assembly includes a plurality of clamping plates 15 circumferentially distributed on the side of the turntable 8 close to each other. The side of the clamping plate 15 away from the turntable 8 is provided with a clamping groove 16 that is movably fitted with the wire body 9. The ends of the two corresponding clamping grooves 16 that are away from each other are connected with a slide plate 17 that is slidably fitted with the turntable 8. The end of the slide plate 17 away from the clamping plate 15 is connected with an abutment block 18. A spring 19 that is sleeved on the outside of the slide plate 17 is connected between the abutment block 18 and the turntable 8. Abutment arc plates 20 are symmetrically provided on the inner side of the installation box 1. Abutment arc surfaces 21 are provided on the abutment arc plates 20. The abutment arc surfaces 21 are movably abutted with the abutment block 18 located at the highest point.

[0035] In this embodiment, in the initial state, the two clamping grooves 16 located at the highest point are fitted with the outer wall of the wire body 9 by mutual cooperation. At this time, the spring 2 19 on the slide plate 17 corresponding to the clamping groove 16 is in a contracted state, and the abutment block 18 is away from the inner wall of the installation box 1. The other springs 2 19 are at their original lengths, and the other abutment blocks 18 are close to the inner wall of the installation box 1. When the transmission assembly drives the rotating rod 7 and the turntable 8 to rotate, the turntable 8 drives the clamping plate 15 to rotate synchronously. The initial state is that the clamping plate 15 fitted with the wire body 9 rotates downward, and the spring 2 19 thereon extends and pushes the abutment block 18 close to the inner wall of the installation box 1. The rear clamping plate 15 rotates upward. At the same time, the rear abutment block 18 begins to abut against the abutment arc surface 21, and the spring The two 19 are stressed and contracted, and the abutting arc surface 21 drives the symmetrical clamping plates 15 to approach each other by pushing the abutting block 18 away from the inner wall of the installation box 1. The corresponding clamping plates 15 clamp the wire body 9 by approaching each other to avoid slipping of the wire body 9 during the feeding process. During the continuous rotation of the rotating rod 7 and the rotating disk 8, stable feeding of the wire body 9 can be achieved, wherein a plurality of storage grooves 14 are circumferentially distributed on one side of the rotating disk 8 where they are close to each other, and the number of the storage grooves 14 is consistent with the number of the clamping plates 15. By setting the storage grooves 14, the spacing between the corresponding clamping plates 15 is facilitated, thereby meeting the feeding requirements of wire bodies 9 of different specifications and improving the applicability of the device. The abutting arc surface 21 is set as a human-shaped arc surface.

[0036] In one embodiment of the present invention, see Figure 1 and Figure 2 The extrusion assembly includes an extrusion plate 10 movably arranged on the top of the inner side of the installation box 1, and a groove movably fitted with the wire body 9 is provided at the bottom of the extrusion plate 10. A vertical rod 11 connected to the extrusion plate 10 is slidably provided on the top of the installation box 1. The other end of the vertical rod 11 passes through the installation box 1 and is connected to the connecting plate 12. A spring 13 sleeved on the outside of the vertical rod 11 is connected between the installation box 1 and the extrusion plate 10.

[0037] In this embodiment, the spring 13 squeezes the extrusion plate 10 downward so that the groove of the extrusion plate 10 fits with the upper surface of the wire body 9, which facilitates the stable extrusion of the wire body 9 between the symmetrically arranged turntables 8, facilitates the stable feeding of the wire body 9, and improves the feeding efficiency.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
