DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0021] Example 1: This embodiment provides a fully automatic winding machine for 3D printing consumables, comprising: The frame 1 is provided with a workbench 11, and a support plate 12 is provided on the workbench 11; The feeding mechanism 2 is mounted on the workbench 11 and is used to feed the wire winding reel; A wire winding mechanism, mounted on the support plate 12, and used to secure and wind 3D printing consumables on the wire winding reel; The unloading mechanism 3 is installed on the workbench 11 and is used to unload the wire winding disc for completing the winding; The transfer mechanism 4 is installed on the workbench 11 and is used to move the wire winding reel on the workbench 11.

[0022] It can be seen from this embodiment that the wire winding reel is loaded through the loading mechanism 2, and the wire winding reel is unloaded through the unloading mechanism 3, and the wire winding reel is transferred between the loading mechanism 2 and the wire winding mechanism and between the wire winding mechanism and the unloading mechanism 3 through the transfer mechanism 4, which reduces manual participation, saves time and effort, and allows a single person to look after multiple winding machines, effectively improving work efficiency.

[0023] Example 2: This embodiment provides a fully automatic winding machine for 3D printing consumables. In addition to the technical solutions of the above embodiments, it also has the following technical features. The winding mechanism includes: The rotating assembly 5 is used to drive the rotation of the filament winding disk, and is provided with a consumable material feeding assembly 6 for feeding 3D printing consumables and a tape feeding assembly 7 for feeding tape on both sides; The pressing assembly 8 is installed above the rotating assembly 5 and is used to press the tape on the filament winding reel to fix the end of the 3D printing consumables; Among them, a tape cutting component 9 for cutting the tape and a consumable cutting component 10 for cutting the 3D printing consumables after winding are respectively provided on both sides of the rotating component 5.

[0024] It can be seen from this embodiment that the various components in the above-mentioned winding mechanism facilitate the loading and cutting of 3D printing consumables, and at the same time, the end of the 3D printing consumables is fixed by the tape, ensuring that when the rotating component 5 rotates, the 3D printing consumables can be automatically wound on the winding disk to complete the winding, and the pressing component 8 facilitates the stability of the tape when it is pasted and fixed to the end of the 3D printing consumables to avoid false sticking.

[0025] Example 3: This embodiment provides a fully automatic winding machine for 3D printing consumables. In addition to the technical solutions of the above embodiments, it also has the following technical features. The rotating component 5 includes: The sleeve 50 is provided through the support plate 12 and is rotatably connected to the support plate 12, and has a plurality of circumferentially arranged clamping claws 500 formed at the end thereof; The pull rod 51 is coaxially slidably mounted in the sleeve 50 and has a conical head 510 at one end close to the clamping claws 500. When the pull rod 51 moves axially, it can push the conical head 510 to squeeze the multiple clamping claws 500 to clamp the wire winding reel. The spring 52 and the inner wall of the sleeve 50 are provided with an annular groove 501, and the surface of the pull rod 51 is provided with an annular boss 511. A mounting cavity 53 is formed axially between the annular groove 501 and the annular boss 511. The spring 52 is installed in the mounting cavity 53, and its two ends respectively abut against the inner wall of the annular groove 501 and the axial surface of the annular boss 511, and is used to push the pull rod 51 to squeeze the multiple clamping claws 500. The first cylinder 54 is mounted on the support plate 12 and is used to push the pull rod 51 to compress the spring 52 to release the squeezing of the multiple clamping claws 500, and the output end is not connected to the pull rod 51; There may be three clamping claws 500 , and the pull rod 51 and the conical head 510 may be connected in a detachable fixed manner, such as a threaded connection.

[0026] It can be seen from the present embodiment that the spring 52 and the first cylinder 54 are used to apply force to the pull rod 51 in two axial directions, thereby pushing the conical head 510 to move in two axial directions to achieve clamping and locking of the wire winding disk and release of the clamping and locking, thereby improving convenience and efficiency. The output end of the first cylinder 54 is not connected to the pull rod 51, ensuring that the pull rod 51 can be pushed axially without affecting the rotation of the pull rod 51. The structure is simple and the manufacturing cost is low.

[0027] Example 4: This embodiment provides a fully automatic winding machine for 3D printing consumables. In addition to the technical solutions of the above embodiments, it also has the following technical features. The rotating component 5 also includes: The driving motor 55 is mounted on the support plate 12 and has an active driving wheel 56 at the conveying end; The driven driving wheel 57 is mounted on the end of the sleeve 50 away from the clamping claw 500 and is linked to the active driving wheel 56 by a transmission belt 58; The bracket 59 is mounted on the support plate 12 and is used to install and connect the first cylinder 54 and the drive motor 55 to the support plate 12, and is connected to the bearing between the sleeve 50; The active driving wheel 56 and the driven driving wheel 57 can be synchronous wheels, and the transmission belt 58 can be a synchronous belt. The specific structure of the driving motor 55 is the existing technology, that is, a conventional motor can be used.

[0028] It can be seen from this embodiment that the driving motor 55 uses the active driving wheel 56, the driven driving wheel 57 and the transmission belt 58 to drive the sleeve 50 to rotate, and then drives the wire winding disk to rotate for winding. This can avoid placing the driving motor 55 at the axial end of the sleeve 50, thereby facilitating the installation of the first cylinder 54 and promoting the axial movement of the pull rod 51 through the push of the first cylinder 54, thereby ensuring the clamping, locking and release of the wire winding disk.

[0029] Example 5: This embodiment provides a fully automatic winding machine for 3D printing consumables. In addition to the technical solutions of the above embodiments, it also has the following technical features: The consumable material feeding assembly 6 includes a horizontal drive unit 60, a vertical drive unit 61, and a second cylinder 62 installed at the output end of the vertical drive unit 61. A mounting plate 63 is provided at the output end of the second cylinder 62, and a tensioning wheel 64, a third cylinder 65, and a guide piece 66 with a guide groove are provided on the mounting plate 63. The consumable material cutting assembly 10 includes a fourth cylinder 100 mounted on the support plate 12 and a pneumatic scissors 101 mounted at the output end of the fourth cylinder 100, and the pneumatic scissors 101 retain a protruding wire piece 66 when cutting the 3D printing consumable material; The horizontal drive unit 60 and the vertical drive unit 61 are used for horizontal and vertical movement when loading 3D printing consumables and winding wires; At the same time, the horizontal drive unit 60 and the vertical drive unit 61 can both use a motor and a screw transmission device 40, and the specific structures thereof, the tensioning wheel 64, the guide wire piece 66 and the pneumatic scissors 101 are all prior art and will not be described in detail here; The second cylinder 62 is horizontally arranged toward one side of the rotating component 5, that is, it is used to push the mounting plate 63 to move horizontally toward the rotating component 5. The third cylinder 65 is horizontally arranged perpendicular to the second cylinder 62, and is used to clamp and release the 3D printing consumables. The fourth cylinder 100 is inclined and is used to push the pneumatic scissors 101 to move obliquely downward.

[0030] It can be seen from this embodiment that the provision of the horizontal drive unit 60 and the vertical drive unit 61 facilitates, on the one hand, the convenience and accuracy of loading the end of the 3D printing consumable, ensuring that the end of the 3D printing consumable is placed in a suitable position and that the tape is adhered and fixed. On the other hand, during wire winding, the horizontal drive unit 60 and the vertical drive unit 61 can change the winding direction and height of the 3D printing consumable, thereby improving the neatness of the winding of the 3D printing consumable on the wire winding reel, avoiding wire clamping and the like during subsequent use, and improving product quality. Furthermore, the arrangement of the tension wheel 64 and the guide wire 66 can improve the accuracy of feeding the 3D printing consumables and further improve the stability and accuracy when the horizontal drive unit 60 and the vertical drive unit 61 change the winding direction and height; At the same time, when the pneumatic scissors 101 cut the 3D printing consumables, a section of the protruding wire piece 66 is retained, so as to facilitate the subsequent loading and ensure that the tape is adhered and fixed to the end of the 3D printing consumables to ensure the stability of the wire winding.

[0031] Example 6: This embodiment provides a fully automatic winding machine for 3D printing consumables. In addition to the technical solutions of the above embodiments, it also has the following technical features. The pressing component 8 includes: The fifth cylinder 80 is mounted on the support plate 12 and is provided with a pressing block 81 at the output end, and an arc-shaped groove 82 is formed at one end of the pressing block 81 close to the winding disk; Among them, the pressing block 81 can be made of rubber; At the same time, the fifth cylinder 80 is vertically arranged to drive the pressing block 81 to move up and down.

[0032] It can be seen from this embodiment that the fifth cylinder 80 pushes the pressing block 81 to perform pressing, which can improve the stability and firmness of the end of the 3D printing consumable when sticking it in the early stage of winding. After the winding is completed, the 3D printing consumable can be pre-sticked and fixed by the adhesive tape before cutting, ensuring that the end of the 3D printing consumable formed after cutting is firmly fixed to the wound 3D printing consumable, preventing the 3D printing consumable on the winding reel from spreading, and effectively ensuring product quality. At the same time, the opening of the arc-shaped groove 82 and the use of rubber material for the pressing block 81 can improve the fixing effect of the 3D printing consumables when pressing down and ensure full coverage of the tape, thereby ensuring the adhesive effect of the tape, that is, improving the fixing effect of the end of the 3D printing consumables.

[0033] Example 7: This embodiment provides a fully automatic winding machine for 3D printing consumables. In addition to the technical solutions of the above embodiments, it also has the following technical features: The tape feeding assembly 7 includes a sixth cylinder 70 mounted on the support plate 12, a seventh cylinder 71 mounted at the output end of the sixth cylinder 70, and a tape mounting bracket 72 mounted at the output end of the seventh cylinder 71. The tape mounting bracket 72 is equipped with a guide roller 73 for guiding the tape feeding and a guide block 74 with a guide groove. The tape cutting assembly 9 includes a connecting plate 90 mounted on the output end of the fifth cylinder 80, an eighth cylinder 91 mounted on the connecting plate 90, and a cutter 92 mounted on the output end of the eighth cylinder 91; The tape installation frame 72 is provided with a tape roll 75 for supplying tape, and the tape installation frame 72 includes a support column 720 for rotatably installing the tape roll 75 and a ninth cylinder 721 for limiting the rotation of the tape roll 75; At the same time, the guide roller 73 and the cutter 92 are both existing mature technologies, which are suitable for achieving the desired effect. The specific structure is not limited in this application; The sixth cylinder 70 is vertically arranged and is used for the vertical lifting and lowering of the seventh cylinder 71, and the seventh cylinder 71 is horizontally arranged and is used to push the tape mounting frame 72 toward or away from the rotating component 5. The eighth cylinder 91 is vertically arranged and is used to cut the tape downward and lift it for reset. The ninth cylinder 721 is vertically arranged and is used to push downward to limit the rotation of the tape roll 75.

[0034] As can be seen from this embodiment, the height of the tape mounting frame 72 is adjusted by the sixth cylinder 70 so that the guide block 74 corresponds to the empty wire winding reel and the wire winding reel after winding, respectively, so as to facilitate the affixing and fixing of the 3D printing consumables before and after winding. The seventh cylinder 71 facilitates pushing the guide block 74 to extend the end of the tape above the wire winding reel and below the pressing assembly 8. At the same time, when the pressing assembly 8 squeezes and fixes the end of the tape, the seventh cylinder 71 is reset, so that the tape is pulled out from the tape roll 75. The guide roller 73 can optimize the tearing angle of the tape and reduce noise, while the guide block 74 can ensure that the end of the tape is pulled out to a sufficient length to penetrate between the winding reel and the pressing assembly 8 and maintain stability at a long length. In addition, the ninth cylinder 721 can clamp the tape roll 75 after being pushed out, thereby limiting the rotation of the tape roll 75, thereby ensuring the effect of the cutter 92 on cutting the tape, and avoiding obstruction of the tape cutting due to the rotation of the tape roll 75; at the same time, after fixing the two ends of the tape by the pressing assembly 8 and the ninth cylinder 721, when the tape is cut by the cutter 92, the end of the tape can be selectively protruded from the guide block 74 for a section, thereby facilitating the subsequent movement of the tape end to between the winding disk and the pressing assembly 8, avoiding obstruction of the downward pressure of the pressing assembly 8 by the guide block 74.

[0035] Example 8: This embodiment provides a fully automatic winding machine for 3D printing consumables. In addition to the technical solutions of the above embodiments, it also has the following technical features: The loading mechanism 2 and the unloading mechanism 3 each include two parallel guide rods 20 and support seats 21 installed at both axial ends of the two guide rods 20; The loading mechanism 2 and the unloading mechanism 3 are arranged in parallel, and the loading mechanism 2 further includes a quantitative pushing device 22 installed between the two guide rods 20; At the same time, the quantitative pushing device 22 can adopt a motor, a screw transmission device 40 and a push plate installed on the screw transmission device 40, and realizes the quantitative pushing of the wire winding disk by controlling the quantitative rotation of the motor. The specific structure of each component is the existing technology and will not be repeated here. The connection between the support seat 21 and the guide rod 20 is open on the side close to the wire winding disc to avoid obstruction to the movement of the wire winding disc along the guide rod 20. The unloading mechanism 3 can also use the following hopper with a collection frame or a conveyor belt device to collect and transfer the wound wire reels.

[0036] It can be seen from this embodiment that the two parallel guide rods 20 can improve the stability of the support for the wire winding reel, and with the push of the quantitative pushing device 22, after the previous wire winding reel is grabbed by the transfer mechanism 4, the next wire winding reel can be added to the position of the previous wire winding reel, ensuring subsequent grabbing; Place it on the unloading mechanism 3. When the transfer mechanism 4 grabs the wound wire reel and moves it to the unloading mechanism 3, it is pushed one by one until the two guide rods 20 in the unloading mechanism 3 are away from the wire reel on one end of the transfer mechanism 4 and are pushed through the unloading hopper and fall into the mobile phone frame or conveyor belt device.

[0037] Example 9: This embodiment provides a fully automatic winding machine for 3D printing consumables. In addition to the technical solutions of the above embodiments, it also has the following technical features: the transfer mechanism 4 includes: The screw drive device 40 is mounted on the workbench 11 and has a tenth cylinder 41 at its output end; A support frame 42 is installed at the output end of the tenth cylinder 41; The clamping cylinder 43 is mounted on the support frame 42 and is used to clamp and grab the wire winding reel; The tenth cylinder 41 is arranged horizontally and perpendicular to the conveying direction of the screw transmission device 40; At the same time, the clamping cylinder 43 is a three-claw clamping cylinder 43, and the specific structure of the screw transmission device 40 is the existing technology and will not be repeated here.

[0038] It can be seen from this embodiment that the coordination of the screw drive device 40, the tenth cylinder 41, and the clamping cylinder 43 effectively improves the stability of the wire winding reel during transfer, and the tenth cylinder 41 facilitates the clamping of the wire winding reel by the clamping cylinder 43. At the same time, after the wire winding reel is clamped by the clamping cylinder 43, when it moves to the sleeve 50, the wire winding reel is pushed onto the sleeve 50, and the conical head 510 can be pushed with the help of the clamping claws of the clamping cylinder 43, which can effectively avoid the conical head 510 or the pull rod 51 from getting stuck due to accidents, and thus effectively ensure that the clamping claws 500 at the end of the sleeve 50 clamp the wire winding reel.

[0039] Example 10: This embodiment provides a winding process of a fully automatic winding machine for 3D printing consumables, comprising the following steps: S1: The equipment starts and the wire winding reel is loaded into the upper feeding mechanism 2; S2: The transfer mechanism 4 moves to the feeding mechanism 2 and grabs the wire winding reel and then moves to the rotating assembly 5; S3: The filament loading component 6 loads the 3D printing filament, and then the tape loading component 7 loads the tape; S4: The pressing component 8 presses down, squeezes the tape to stick and fix the end of the 3D printing consumable, and cuts the tape by the tape cutting component 9; S5: The pressing assembly 8 moves upward and resets, and the rotating assembly 5 drives the filament winding disc to rotate to wind the 3D printing filament; S6: After the winding is completed, the tape feeding component 7 feeds the tape, and the pressing component 8 presses down to squeeze the tape to stick and fix the end of the 3D printing filament; S7: The filament cutting assembly 10 cuts the 3D printing filament, the tape cutting assembly 9 cuts the tape, and the pressing assembly 8 moves upward and resets; S8: The transfer mechanism 4 grabs the wire winding disc that has completed the winding and moves it to the unloading mechanism 3 for unloading; S9: repeat S2-S9; In S2, specifically, the screw transmission device 40 drives the clamping cylinder 43 to move to the feeding mechanism 2. Under the action of the tenth cylinder 41, the clamping cylinder 43 is pushed to the wire winding disk for grabbing. Then the tenth cylinder 41 is reset, and the screw transmission device 40 moves to the rotating component 5. In S3, the third cylinder 65 clamps the 3D printing filament and is moved to a suitable position by the horizontal drive unit 60 and the vertical drive unit 61. Then, the second cylinder 62 pushes the mounting plate 63 toward the side of the rotating assembly 5, so that the section of 3D printing filament protruding from the wire sheet 66 is placed between the wire winding disk and the pressing assembly 8. The sixth cylinder 70 drives the guide block 74 to be flush with the inner surface of the wire winding disk. Under the drive of the seventh cylinder 71, the end of the tape moves between the wire winding disk and the pressing assembly 8 and is located above the 3D printing filament. In S4, the fifth cylinder 80 pushes the pressing block 81 downward, squeezing the tape to adhere the end of the 3D printing filament to the inner surface of the filament winding disk. Then, the seventh cylinder 71 resets, pulling the tape roll 75 to rotate and unload the tape. Then, the ninth cylinder 721 restricts the rotation of the tape roll 75. The eighth cylinder 91 pushes the cutter 92 downward to cut the tape, leaving a section of the protruding guide block 74. In S5, the fifth cylinder 80 drives the press block 81 to move upward, the third cylinder 65 releases the clamping of the 3D printing filament, and the drive motor 55 starts the sleeve 50 to rotate, that is, the filament winding disk rotates, pulling the 3D printing filament to be wound on the filament winding disk, and the horizontal drive unit 60 and the vertical drive unit 61 adjust the feeding angle and height of the 3D printing filament in real time so that it is wound on the filament winding disk in an orderly manner; In S6, the sixth cylinder 70 is lifted, and the seventh cylinder 71 is started again, pushing the guide block 74 to be flush with the 3D printing consumables in the wound filament reel. The fifth cylinder 80 drives the pressing block 81 to press down, and the 3D printing consumables are fixed with tape. In S7, the fourth cylinder 100 pushes the pneumatic scissors 101 downward onto the 3D printing filament, and starts the pneumatic scissors 101 to cut the 3D printing filament. The pneumatic scissors 101 are then reset by the fourth cylinder 100, and the fifth cylinder 80 drives the press block 81 upward to reset. In S8, the tenth cylinder 41 pushes the clamping cylinder 43 to move out and re-clamp the wire winding disk, and the first cylinder 54 pushes the pull rod 51, thereby causing the conical head 510 to move axially, releasing the clamping claw 500 from the wire winding disk, and then the tenth cylinder 41 is reset and moved to the unloading mechanism 3 for unloading under the action of the screw transmission device 40.

[0040] As can be seen from this embodiment, through the above-mentioned winding process, only the empty winding reel needs to be loaded manually onto the loading mechanism 2, which greatly reduces the involvement of manual labor, saves time and effort, and enables a single operator to look after multiple winding machines, thereby significantly reducing production costs and improving production efficiency. Furthermore, a robot can be used to load the empty wire winding reel, further improving production efficiency and achieving no human intervention.

[0041] In this application, the first cylinder 54, the second cylinder 62, the third cylinder 65, the fourth cylinder 100, the fifth cylinder 80, the sixth cylinder 70, the seventh cylinder 71, the eighth cylinder 91, the ninth cylinder 721 and the tenth cylinder 41 are used, all of which are traditional and commonly used cylinders and are existing mature technologies, and will not be described in detail without further application.
