Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a PCL consumables recycling device for 3D printing. Background Art

[0002] 3D printing (3DP) is a type of rapid prototyping technology, also known as additive manufacturing [1]. It is a technology that uses 3D model files as the basis and uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing, industrial design, etc., and later gradually used for the direct manufacturing of some products. There are already parts printed using this technology.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese patent publication number: CN217514571U discloses a 3D printing consumable waste recycling device, including a recycling box, wherein a cutting mechanism, a rolling mechanism, and a heating mechanism are arranged inside the recycling box, wherein the cutting mechanism includes a feed hopper, wherein the rolling mechanism includes a rolling wheel, a fixing plate, and a scraper, wherein the cutting mechanism is located directly above the rolling mechanism, wherein the heating mechanism includes a heating box, wherein the heating mechanism is located directly below the rolling mechanism. The beneficial effect of the utility model is that during the operation of the device, the waste can be cut by the arranged cutting mechanism, and the cut waste automatically falls between the two rolling wheels through the feed hopper, and then is crushed by the arranged crusher. The structure crushes the waste, and the crushed waste falls into the interior of the heating box, which can melt the waste inside and finally discharge it through the discharge pipe, so that it is convenient to melt and recycle the waste, and improve the efficiency of waste recycling. However, during the use of the utility model, the waste after high-temperature melting is directly discharged through the discharge pipe without being processed. However, what we know is that 3D materials will produce irritating odors during the melting process. When the staff inhales it for a long time, it will cause physical and mental damage to the staff. Moreover, the high-temperature waste is directly discharged, which is inconvenient for the later workers to process it, and there is even the possibility that the staff will be scalded when processing it.

[0005] To this end, we proposed a PCL consumables recycling device for 3D printing to solve the above drawbacks. Utility Model Content

[0025] Specifically: During the use of the utility model, the staff opens the recycling device, and then the staff puts the waste into the feed frame 15. When the waste enters the feed frame 15, the crushing structure 16 crushes the waste, and the crushed waste passes through the gap between the fixed plates 17 and falls to the rolling structure 18. The rolling structure 18 rolls the crushed waste, and the waste after rolling falls into the heating frame 19. At this time, the heating wire 20 is started to heat and melt the waste. After the heating and melting is completed, the melted waste passes through the heating frame 19 and falls into the collection box 8 at the bottom. At this time, the control The device 21 controls the suction fan 7 and the fan 11 to start at the same time. When the suction fan 7 is started, the suction force generated by the suction fan 7 reaches the inside of the groove through the filter box 4 and the conveying pipe 9, thereby adsorbing the pungent odor generated by the heating and melting. The gas after adsorption is transported to the inside of the filter box 4 through the conveying pipe 9. After passing through the activated carbon in the large cavity, the activated carbon filters its pungent odor. The clean gas after filtering passes through the small cavity and enters the inside of the suction fan 7, and is discharged through the exhaust port of the suction fan 7. When the fan 11 is started, it will generate a downward blow, and cooperate with the suction fan 7 to extract the internal heat at the same time, thereby achieving a rapid cooling effect.

[0026] In this embodiment: a feed frame 15 is fixedly installed on the upper surface of the recovery device body 1, a crushing structure 16 is arranged inside the feed frame 15, a fixing plate 17 is fixedly installed on the upper inner wall of the recovery device body 1, a crushing structure 18 is arranged inside the recovery device body 1, a heating frame 19 is fixedly installed on the inner wall of the recovery device body 1, a heating wire 20 is arranged inside the heating frame 19, a controller 21 is fixedly installed on the front surface of the recovery device body 1, and a support column 22 is fixedly installed on the lower surface of the recovery device body 1.

[0027] Specifically: the staff turns on the recycling device, and then the staff puts the waste into the feed frame 15. When the waste enters the feed frame 15, the crushing structure 16 crushes the waste, and the crushed waste passes through the gap between the fixed plates 17 and falls to the crushing structure 18. The crushing structure 18 crushes the crushed waste, and the waste after crushing falls into the heating frame 19. The electromagnetic valve is in a closed state at this time, and the heating wire 20 is started to heat and melt the waste. After the heating and melting is completed, the electromagnetic valve opens, and the melted waste passes through the heating frame 19 and falls into the collection box 8 at the bottom.

[0029] Specifically: the suction force generated by the suction fan 7 reaches the inside of the groove through the filter box 4 and the air duct, thereby absorbing the irritating odor. The function of the through hole 12 is to provide a wind exchange channel for the fan 11. The fan 11 always has a downward blow to prevent the irritating odor from flowing out of the through hole 12. The drawer design is convenient for the later treatment of the cooled 3D waste. The function of the barrier filter plate 6 is to block the activated carbon to prevent the activated carbon from directly contacting the connection between the suction fan 7 and the filter box 4, thereby being sucked into the interior by the suction fan 7, causing damage to the suction fan 7.

[0031] Specifically: the crushed 3D waste enters the interior of the recycling device body 1 through the feed hole.

[0032] Working principle: The utility model uses the suction fan 7 and the filter box 4 to achieve the effect of adsorbing and filtering the pungent odor generated after the waste is melted, and the wind force generated by the rotation of the fan 11 can achieve the effect of quickly cooling the high-temperature waste. Compared with the related art, the PCL consumables recovery device for 3D printing provided by the utility model has the following beneficial effects: the design can achieve the effect of adsorbing and filtering the pungent odor generated during the melting process to prevent it from dissipating into the air and affecting the physical and mental health of the staff.

[0036] In this embodiment, the output end of the servo motor 14 is fixedly connected to the right end of the stirring rod 13 .

[0037] Specifically: the servo motor 14 drives the stirring rod 13 to rotate.

[0038] Working principle: This design uses a servo motor 14 to drive the stirring rod 13 to continuously stir the waste passing through the fixed plates 17, thereby preventing the crushed waste from being blocked between the fixed plates 17. Compared with the related art, the PCL consumables recovery device for 3D printing provided by the utility model has the following beneficial effects: This design can continuously break up the waste passing through the fixed plates 17, thereby preventing the waste from being blocked between the fixed plates 17, causing the device to be unable to work.
