Description

Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to a 3D printing drying device. Background Art

[0002] The 3D printing drying device is mainly used to dry the printed object (i.e., the printed part). During the 3D printing process, plastic materials such as ABS and PLA will absorb a certain amount of moisture during printing. If the printed object is not properly dried after printing, the moisture may cause bubbles or fine cracks on the surface of the printed part, affecting its mechanical properties and appearance quality.

[0003] However, when the existing 3D printing drying device is in use, it usually sprays hot air through a nozzle fixedly installed inside the device to dry the printed object. However, since the position of the nozzle is fixed, its air outlet range is limited. This may mean that the nozzle can only effectively dry a part of the printed object, while other parts may not be fully dried because they are not within the effective air outlet range of the nozzle, resulting in different parts of the printed object being affected by hot air to different degrees and causing uneven drying. Summary of the Utility Model

[0010] As a preferred embodiment, the bottom of the hot air blower is fixedly installed on the top of the support member, and a first rotating rod is fixedly installed at the top of the reciprocating lead screw.

[0011] The technical effect of adopting the above further solution is that the first rotating rod can be driven to rotate by the reciprocating lead screw.

[0012] As a preferred embodiment, a small gear is fixedly installed at the top of the first rotating rod, and a plurality of ventilation slots are formed on both sides inside the device body.

[0013] The technical effect of adopting the above further solution is that the small gear can be driven to rotate by the first rotating rod.

[0019] The technical effect of adopting the above further solution is that the second rotating rod can be driven to rotate by the large gear.

[0020] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0030] Embodiment 1, please refer to Figures 1 to 4 , the present utility model provides a technical solution: a 3D printing drying device, including a device body 1. A hinge 101 is fixedly installed on the right side of the device body 1. The inside of the hinge 101 is movably connected with a cover plate 102. The left side of the cover plate 102 is movably connected to the outer surface of the right side of the device body 1. A reciprocating lead screw 103 is movably embedded on the left side inside the device body 1. A motor 104 is fixedly installed at the bottom of the reciprocating lead screw 103. The bottom of the motor 104 is fixedly installed on the left side of the device body 1. A slider 105 is threadedly connected to the outer surface of the reciprocating lead screw 103. Slide grooves 106 are provided on both inner walls of the device body 1. The outer surfaces of both sides of the slider 105 are slidably connected to the inner surfaces of the slide grooves 106. A conveying frame 107 is fixedly installed on the right side of the slider 105. A plurality of nozzles 108 are fixedly installed on the right side inside the conveying frame 107. A hose 109 is fixedly installed on the front side of the conveying frame 107. The outer surface of the hose 109 is movably embedded inside the device body 1. The other end of the hose 109 is fixedly installed with a hot air blower 110. A support member 115 is fixedly installed at the bottom of the device body 1. The bottom of the hot air blower 110 is fixedly installed on the top of the support member 115. A first rotating rod 113 is fixedly installed at the top of the reciprocating lead screw 103. A small gear 114 is fixedly installed at the top of the first rotating rod 113. A plurality of ventilation slots 111 are provided on both inner sides of the device body 1. Dust-proof nets 112 are fixedly installed on both inner walls of the device body 1 and on the inner sides of the plurality of ventilation slots 111. A second rotating rod 2 is movably embedded at the center inside the device body 1.

[0031] In this embodiment, the user can first place the bottom of the support member 115 against the ground, and then place the device body 1. Then, pull the cover plate 102 backward to make it flip backward through the hinge 101, thereby opening the device body 1. Place the printed object inside the device body 1. After closing the cover plate 102, start the hot air blower 110 through the power supply system of the hot air blower 110. When it is running, hot air is conveyed into the inside of the conveying frame 107 through the hose 109, and the hot air is transported by the conveying frame 107 so that the hot air enters the inside of the nozzle 108, and then the hot air is ejected from the nozzle 108 to dry the object. At the same time, the hot air can pass through the ventilation slot 111 and the dust-proof net 112 to discharge the inside of the device body 1, thereby ventilating the inside of the device body 1. And when the nozzle 108 is ejecting air, the motor 104 can be started through the power supply system of the motor 104. When it is running, the output shaft drives the reciprocating lead screw 103 to rotate. When the reciprocating lead screw 103 rotates, it can drive the slider 105 to perform reciprocating translational motion up and down through the chute 106. Thus, when the slider 105 moves, it can drive the nozzle 108 to move synchronously through the conveying frame 107, thereby increasing the spraying range of the nozzle 108 and drying the object in all directions. And through structures such as the nozzle 108 and the reciprocating lead screw 103, the up-and-down reciprocating motion of the nozzle 108 is realized, thereby increasing the spraying range of the nozzle 108, ensuring that the printed object can be dried in all directions, and improving the uniformity and efficiency of drying of the device body 1.

[0032] Embodiment 2, as Figures 1 to 4 shown, a large gear 201 is fixedly installed at the top of the second rotating rod 2. The large gear 201 meshes with the adjacent small gear 114. Both sides of the outer surface of the second rotating rod 2 are fixedly sleeved with connecting members 202, and a plurality of hooks 203 are fixedly installed at the bottom of the two connecting members 202.

[0033] In this embodiment, the user can hang multiple printed objects on the hooks 203 inside the connecting members 202 in sequence and close the cover plate 102 to dry the objects. When the reciprocating lead screw 103 rotates, it will drive the small gear 114 to rotate through the first rotating rod 113, and then the small gear 114 drives the large gear 201, and then the large gear 201 drives the second rotating rod 2 to rotate. When the second rotating rod 2 rotates, it drives the hooks 203 to rotate through the connecting members 202, thereby changing the positions of the objects on the hooks 203. And through structures such as the hooks 203 and the large gear 201, the device can not only dry multiple printed objects, but also significantly improve the drying efficiency, reduce the total drying time, thereby improving the production efficiency. At the same time, the rotation of the hooks 203 ensures that the hot air can evenly cover all angles of the printed object, further avoiding the problem of uneven drying caused by the fixed nozzle 108.

[0034] Working principle: When in use, the user can first place the bottom of the support member 115 against the ground, and then place the device body 1. Then, pull the cover plate 102 backward so that it flips backward through the hinge 101 to open the device body 1. Place the printed object inside the device body 1. After closing the cover plate 102, start the hot air blower 110 through the power supply system of the hot air blower 110. When it is running, it conveys hot air into the inside of the conveying rack 107 through the hose 109, and transports the hot air through the conveying rack 107 so that the hot air enters the inside of the nozzle 108, and then the nozzle 108 sprays the hot air to dry the object. At the same time, the hot air can pass through the ventilation slot 111 and the dust-proof net 112 to discharge from the inside of the device body 1 to ventilate the inside of the device body 1. And when the nozzle 108 is spraying air, the motor 104 can be started through the power supply system of the motor 104. When it is running, the output shaft drives the reciprocating lead screw 103 to rotate. When the reciprocating lead screw 103 rotates, it can drive the slider 105 to perform reciprocating translational motion up and down through the chute 106. Then, when the slider 105 is moving, it can drive the nozzle 108 to move synchronously through the conveying rack 107, thereby increasing the spraying range of the nozzle 108 and drying the object in all directions. And through structures such as the nozzle 108 and the reciprocating lead screw 103, the up-and-down reciprocating motion of the nozzle 108 is realized, thereby increasing the spraying range of the nozzle 108, ensuring that the printed object can be dried in all directions, and improving the uniformity and efficiency of drying of the device body 1. When in use, the user can hang multiple printed objects on the hooks 203 inside the connecting member 202 in sequence, and close the cover plate 102 to dry the objects. When the reciprocating lead screw 103 rotates, it will drive the small gear 114 to rotate through the first rotating rod 113, and then the small gear 114 drives the large gear 201, and then the large gear 201 drives the second rotating rod 2 to rotate. When the second rotating rod 2 rotates, it drives the hook 203 to rotate through the connecting member 202, thereby changing the position of the object on the hook 203. And through structures such as the hook 203 and the large gear 201, the device can not only dry multiple printed objects, but also significantly improve the drying efficiency, reduce the total drying time, thereby improving the production efficiency. At the same time, the rotation of the hook 203 ensures that the hot air can evenly cover all angles of the printed object, further avoiding the problem of uneven drying caused by the fixed nozzle 108.

[0035] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
