Description

Technical Field

[0001] This utility model relates to the field of printer accessories technology, specifically a printer wire harness winding machine. Background Technology

[0002] In the 3D printing process, filament winding is an essential preliminary step. The stability and integrity of the filament during winding directly affect the smoothness of subsequent printing. However, currently, when winding 3D printing filament onto winding rollers, the rollers are generally made of relatively hard materials. During winding, the filament is in close contact with the surface of the rigid winding roller. When the winding roller rotates, the filament is subjected to significant friction and rigid pulling from the roller. Once the filament breaks due to rigid pulling, it results in direct material waste and increased production costs. Frequent filament breakage requires operators to frequently stop their work and spend extra time and effort to reassemble and reconnect the broken filament, which undoubtedly reduces overall production efficiency.

[0003] In view of the above, this application is hereby submitted. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a printer wire harness winding machine, including a base plate 1, a partition 2 covering the top surface of the base plate 1, a wire inlet 3 at the front end of the partition 2, and a winding assembly for winding the wire harness inside the partition 2. The winding assembly includes a hollow shaft 4 rotatably mounted on the two narrow side walls of the partition 2. One end of the hollow shaft 4 extending into the interior of the partition 2 is connected to a winding reel 5. The side of the winding reel 5 away from the hollow shaft 4 has an inwardly recessed sliding opening 6. A slider 7 is slidably mounted inside the sliding opening 6. A winding rod 8 is connected between two opposing sliders 7. A support spring 10 is connected to the side wall inside the winding reel 5 where the slider 7 extends into the interior. The other end of the support spring 10 is connected to a movable block 9, which is adjustablely mounted inside the winding reel 5.

[0023] Specifically, the wire harness enters the diaphragm 2 through the inlet 3. The hollow shaft 4 rotates, driving the winding disc 5 to rotate. The slider 7 can slide within the sliding opening 6. The winding rod 8 connects two opposing sliders 7. The support spring 10 connects the slider 7 and the movable block 9. The movable block 9 is adjustablely positioned inside the winding disc 5. During the winding process, when the wire is pulled, the slider 7 can slide within the sliding opening 6. The extension and retraction of the support spring 10 provides cushioning. This design effectively solves the problem of wire breakage due to hard pulling in the prior art, reduces hard pulling, improves the stability and integrity of the wire winding process, reduces the probability of wire breakage, reduces material waste and production costs, and improves production efficiency.

[0024] See Figures 2-4It also includes an adjustment mechanism set inside the winding reel 5 for adjusting the linear displacement of the movable block 9 along the radial direction of the winding reel 5 to adjust the elastic force of the support spring 10. The adjustment mechanism includes an adjustment shaft 11 rotatably inserted into the hollow shaft 4. One end of the adjustment shaft 11 extending into the winding reel 5 is connected to an adjustment gear 13. A linkage shaft 14 is rotatably installed inside the winding reel 5. A lower gear 15 and an upper gear 16 are installed on the linkage shaft 14. The lower gear 15 is meshed with the adjustment gear 13. A transmission rack 17 is installed on the side wall of the movable block 9. The upper gear 16 is meshed with the transmission rack 17.

[0025] Specifically, rotating the adjusting shaft 11 drives the adjusting gear 13 to rotate. The adjusting gear 13 meshes with the lower gear 15, thereby driving the linkage shaft 14 to rotate. The upper gear 16 on the linkage shaft 14 meshes with the transmission rack 17 on the movable block 9, thereby adjusting the radial linear displacement of the movable block 9 along the winding disc 5, changing the compression degree of the support spring 10, and thus adjusting the elastic force of the support spring 10. Through this principle, the equipment can flexibly adjust the elastic force of the support spring 10 according to different materials and thicknesses of wires, further improving the adaptability to various wires, better ensuring the stability of wire winding, and reducing breakage problems caused by differences in wire characteristics.

[0026] See Figure 2 A locking bolt 12 is threaded onto the outer wall of the hollow shaft 4, and one end of the locking bolt 12 extends into the interior of the hollow shaft 4 and abuts against the outer wall of the adjusting shaft 11.

[0027] Specifically, by tightening or loosening the locking bolt 12, one end of it extending into the hollow shaft 4 abuts against or separates from the outer wall of the adjusting shaft 11, thereby fixing or releasing the position of the adjusting shaft 11. This prevents accidental rotation of the adjusting shaft 11 during winding, which could cause a change in the elasticity of the support spring 10. This ensures the stability of the working state of the support spring 10 after its elasticity is adjusted, avoids affecting the winding quality of the wire due to unexpected changes in the adjusting mechanism, and ensures stable operation of the equipment.

[0028] See Figure 2 Multiple sliders 7 are provided, and the multiple sliders 7 are distributed at equal intervals along the circumference of the winding disc 5.

[0029] Specifically, multiple sliders 7 are evenly distributed around the circumference of the winding reel 5, making the force on the winding rod 8 on the winding reel 5 more uniform. During the winding process, the filament can be wound more evenly on the winding rod 8. This helps to improve the uniformity of filament winding, avoids inconsistent filament winding tightness due to uneven local force, ensures the stability of filament delivery during subsequent 3D printing, and improves the quality of the printed product.

[0030] See Figure 2A reciprocating screw 18 is rotatably mounted on the inner wall of the diaphragm 2. A threaded seat 21 is threadedly connected to the reciprocating screw 18. A wire hole 22 for the wire harness to pass through is opened on the threaded seat 21. A drive motor 19 for driving the reciprocating screw 18 to rotate is installed on the outer wall of the diaphragm 2.

[0031] Specifically, the drive motor 19 drives the reciprocating screw 18 to rotate, and the threaded seat 21 is threaded onto the reciprocating screw 18, thereby causing the threaded seat 21 to reciprocate linearly along the reciprocating screw 18. The wire harness passes through the wire hole 22, and under the reciprocating motion of the threaded seat 21, the wire is uniformly wound back and forth on the winding rod 8. This achieves uniform winding of the wire on the winding rod 8, avoids the wire from being concentrated in a certain area of ​​the winding rod 8, further improves the quality and stability of the wire winding, and reduces the risk of abnormal wire stress and breakage caused by uneven winding.

[0032] See Figure 2 Inside the diaphragm 2, a guide rod 20 is also installed, and a threaded seat 21 is slidably connected to the guide rod 20.

[0033] Specifically, the guide rod 20 provides guidance for the movement of the threaded seat 21, making the threaded seat 21 more stable when it reciprocates linearly along the reciprocating screw 18, and preventing the threaded seat 21 from deviating or shaking during the movement. This ensures the stability of the reciprocating winding of the wire driven by the threaded seat 21, improves the accuracy of the wire winding, helps to improve the overall winding quality, and reduces the adverse effects on the wire caused by the unstable movement of the threaded seat 21.

[0034] See Figure 1 and Figure 2 Synchronous pulleys 23 are installed on the outer wall of the hollow shaft 4 and the outer wall of the reciprocating screw 18, and a synchronous belt 24 is connected between the two synchronous pulleys 23 for transmission.

[0035] Specifically, when the hollow shaft 4 rotates, it drives the reciprocating screw 18 to rotate synchronously via the synchronous pulley 23 and the synchronous belt 24. This ensures that the rotation of the winding disc 5 and the reciprocating motion of the threaded seat 21 are synchronized and coordinated, guaranteeing a more uniform and orderly winding of the wire on the winding rod 8. This further optimizes the overall collaborative working capability of the equipment, ensures the uniformity and stability of the wire winding, improves the working efficiency and winding quality of the equipment, and reduces wire winding problems caused by uncoordinated movements.

[0036] See Figure 2 The reciprocating screw 18 and the winding rod 8 are arranged in parallel, and both the reciprocating screw 18 and the wire hole 22 are located on the front side of the winding rod 8.

[0037] Specifically, the reciprocating screw 18 is arranged parallel to the winding rod 8, and both the reciprocating screw 18 and the threading hole 22 are located in front of the winding rod 8. This layout allows the wire to be wound onto the winding rod 8 at a suitable angle and position after passing through the threading hole 22, ensuring smooth winding. The reasonable layout design provides a good path and angle for the winding of the wire, which helps to improve the efficiency and quality of wire winding and reduce problems such as poor winding and breakage caused by unreasonable layout.

[0038] Working principle: The wire harness enters the diaphragm 2 from the inlet 3. The winding disc 5 rotates under the drive of the hollow shaft 4 to wind the wire. The slider 7 can slide in the sliding port 6. It is connected to the movable block 9 through the support spring 10. When the wire is pulled, the support spring 10 extends and retracts to provide cushioning and reduce hard pulling.

[0039] The movable adjusting shaft 11, through the transmission of the adjusting gear 13, the lower gear 15, the linkage shaft 14, the upper gear 16 and the transmission rack 17, adjusts the displacement of the movable block 9 and changes the elastic force of the support spring 10 to adapt to different wires; the position of the adjusting shaft 11 is fixed or released by the locking bolt 12 to prevent the adjusting mechanism from changing unexpectedly.

[0040] Multiple sliders 7, evenly distributed around the circumference of the winding reel 5, ensure uniform force on the winding rod 8. The drive motor 19 drives the reciprocating screw 18 to rotate, causing the threaded seat 21 to reciprocate linearly. The wire passes through the threading hole 22 and is evenly wound back and forth on the winding rod 8. The guide rod 20 guides the threaded seat 21, ensuring smooth movement. Simultaneously, the hollow shaft 4 and the reciprocating screw 18 rotate synchronously via the synchronous pulley 23 and synchronous belt 24, coordinating the winding and reciprocating motion. The reciprocating screw 18 is parallel to the winding rod 8 and located in front of it, ensuring the wire is wound at the appropriate angle and position.

[0041] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
