[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings.
[0021] Example: A filament winding aid for 3D printing, such as... Figures 1-5 As shown, the device includes a base plate 1, a support plate 2, a control center 3, a first winding rod 4, a second winding rod 5, a rotating plate 6, a take-up rod 7, a mounting plate 8, a screw 9, a guide plate 10, a fixing frame 11, a connecting plate 12, a cylinder 16, a connecting rod 17, a moving plate 18, a clamping plate 19, and an elastic element 20. The base plate 1 serves as the mounting carrier for the parts. Four heightening columns are connected to the lower side of the base plate 1, arranged in a rectangular shape, for raising the base plate 1. A support plate 2 is welded to the left side of the front side of the base plate 1. The control center 3 is mounted on the upper side of the base plate 1. A first winding rod 4 is welded to the upper part of the side facing the support plate 2 of the base plate 1. A second winding rod 5 is welded to the upper part of the side facing the support plate 2 of the base plate 1. The first winding rod 4 is located to the lower left of the second winding rod 5. A rotating plate 6 is rotatably connected to the front side of the control center 3. A winding rod 7 is connected to the front side of the rotating plate 6. An mounting plate 8 is connected to the upper part of the front side of the control center 3 and the rear side of the support plate 2. A screw 9 is rotatably connected between the two mounting plates 8. The screw 9 is located to the right of the second winding rod 5. A guide plate 10 is threaded on the screw 9. The guide plate 10 has openings... A circular guide groove is used to guide the wire. A fixing frame 11 is welded to the upper front side of the control center 3, and the fixing frame 11 is located above the take-up bar 7. A connecting plate 12 is welded to the lower front side of the control center 3, and the connecting plate 12 is located below the take-up bar 7. Cylinders 16 are installed on the fixing frame 11 and the connecting plate 12. Connecting rods 17 are symmetrically slidably connected to the fixing frame 11 and the connecting plate 12. A movable plate 18 is connected between the ends of two adjacent connecting rods 17 that are close to the take-up bar 7. The two movable plates 18 extend from the adjacent cylinders 16 respectively. The retractable rod is connected to two moving plates 18 that slide towards each other with clamping plates 19. The two clamping plates 19 are arc-shaped and are used to fit the surface of the wound wire. Elastic elements 20 are symmetrically wound between the clamping plates 19 and the moving plates 18. The control center 3 controls the screw 9 and the winding rod 7 to rotate and wind the wire. The guide plate 10 can guide the wire and make the wire flat on the surface of the winding rod. The control start cylinder 16 drives the clamping plates 19 to move towards each other. The two clamping plates 19 can make the wire roll into a tighter and more regular shape.
[0022] like Figures 4-5 As shown, it also includes a first limiting plate 13, a second limiting plate 14, a limiting rod 15, and bolts 21. The first limiting plate 13 is rotatably connected to the front side of the fixing frame 11, and the second limiting plate 14 is rotatably connected to the connecting plate 12. The first limiting plate 13 and the second limiting plate 14 are in contact with each other on the opposite side. The winding rod 7 is detachably provided with a limiting rod 15. The front end of the limiting rod 15 is in contact with the second limiting plate 14. The connection between the first limiting plate 13 and the second limiting plate 14 is detachably provided with bolts 21. The upper right side of the second limiting plate 14 has a combination shape of semi-circle and rectangle to facilitate the limiting of the limiting rod 15.
[0023] When this device is needed, the end of the wire is moved around the first winding rod 4, the second winding rod 5, and the guide plate 10, and finally fixed on the take-up rod 7. The control center 3 controls the start cylinder 16, which extends the telescopic rods of the two cylinders 16, causing the two moving plates 18 to move towards each other. The moving plates 18 move the connecting rod 17, causing the elastic element 20 to compress adaptively, causing the two clamping plates 19 to move towards each other. Then, the screw 9 and the take-up rod 7 are controlled to rotate. The screw 9 causes the guide plate 10 to move repeatedly left and right. The guide plate 10 guides the wire and makes it coiled flat on the surface of the take-up rod 7. When the wire contacts the inner ring of the two clamping plates 19, the two clamping plates 19 are squeezed and move in opposite directions. The elastic element 20 continues to compress, and the two clamping plates 19 can coil the wire into a tighter and more regular shape, facilitating subsequent transportation and storage. During the wire winding process, the limiting rod 15 can... This prevents the take-up rod 7 from shaking during the take-up process and limits the wire wound on the surface of the take-up rod 7. After the take-up operation is completed, the control center 3 controls the screw 9 to stop rotating, and the cylinder 16 telescopic rod shortens to reset the above components. Use tools to remove the bolt 21 from the connection between the first limit plate 13 and the second limit plate 14. Rotate the first limit plate 13 and the second limit plate 14 in opposite directions to disengage them from the limit rod 15. Remove the limit rod 15 from the take-up rod 7 to facilitate the removal of the wound 3D printing wire from the take-up rod 7 and place it in the collection area. Finally, place the limit rod 15 back on the take-up rod 7 and move the first limit plate 13 and the second limit plate 14 towards each other to re-engage the limit rod 15. Use tools to install the bolt 21 back at the connection between the first limit plate 13 and the second limit plate 14. Subsequent take-up operations can be repeated according to the above steps.
[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
