Description

Technical Field

[0001] This utility model belongs to the field of 3D printing technology, specifically relating to a 3D printing consumable drying box. Background Technology

[0002] The working principle of a 3D printer is basically the same as that of a regular printer, except for the consumables. Controlled by a computer, 3D printing consumables are layered to ultimately transform a blueprint on the computer into a physical object. Simply put, a 3D printer is a device that can "print" real 3D objects, such as a robot, a toy car, or various models. The consumables used in 3D printers are constantly exposed to air, and moisture from the air can seep into the consumables, increasing their humidity. When the consumables are heated during use, the moisture inside will evaporate, forming bubbles within the consumables and affecting the printing results. Therefore, it is necessary to remove the moisture from the consumables before printing.

[0003] The existing technology includes a 3D printing consumable drying box with patent publication number CN219968511U. This patent describes a method where 3D printing consumables are stored inside the drying box and discharged through a discharge hole, effectively reducing moisture absorption and minimizing the risk of brittleness, stringing, and breakage during printing. However, in practical use, it still has the following shortcomings: While the drying box uses a desiccant and electric heating device to dry the consumables, uneven heat transfer leads to varying drying efficiency at different locations, reducing the drying effect. Furthermore, the drying box cannot hold consumables of different roll sizes, limiting its applicability.

[0004] Therefore, a 3D printing filament drying box is needed to solve the problems of uneven heat transfer in existing technologies, which leads to different drying efficiencies in different parts of the filament and reduces the drying effect. In addition, the drying box cannot fix filaments of different roll sizes, resulting in a limited range of applications. Utility Model Content

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Please see Figure 1-5 This utility model provides a 3D printing consumable drying box, including a box body 1, a box cover 2, a temperature and humidity sensor 3, a drying mechanism 4, a coil 5, and a fixing mechanism 6. The box cover 2 is located on the top, the temperature and humidity sensor 3 is located inside the upper part of the box body 1, the drying mechanism 4 is located inside the lower part of the box body 1, the fixing mechanism 6 is located inside the middle side of the box body 1, and the coil 5 is installed inside the box body 1 through the fixing mechanism 6.

[0026] The drying mechanism 4 consists of a fan 401, a heating wire 402, a filter screen 403, a cross plate 405, a spring 406, a positioning block 407, and a guide block 408. The bottom surface of the box 1 is symmetrically provided with a through groove adapted to the fan 401. The fan 401 is located inside the through groove. The heating wire 402 is located above the fan 401. The filter screen 403 is located above the heating wire 402. Cross grooves are symmetrically provided on both sides of the bottom surface of the through groove. The cross plate 405 is slidably connected inside the cross groove. The spring 406 is fixedly connected between the cross plate 405 and the side of the cross groove. The positioning block 407 is fixedly connected to the other side of the cross plate 405 and extends into the through groove.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the fan 401 has symmetrically provided positioning grooves 404 on the left and right sides of its outer casing, which are adapted to the positioning block 407.

[0028] The spring 406 on one side of the positioning block 407 provides elastic reset, causing the positioning block 407 to extend into the positioning groove 404 and thus fix the installation of the fan 401.

[0029] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the guide block 408 is symmetrically fixedly connected to the front and rear sides of the fan 401 housing, and the front and rear sides of the through slot are provided with guide slots that are compatible with the guide block 408.

[0030] By sliding the guide block 408 inside the guide groove, the fan 401 can be initially positioned for installation, which facilitates the subsequent fixing of the fan 401.

[0031] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the lid 2 is composed of a lid body 201 and a breathable mesh 204. The lid body 201 has a cavity 202 inside, and the bottom surface of the cavity 202 has symmetrical ventilation holes 203. The breathable mesh 204 is symmetrically fixedly connected to the left and right ends of the cavity 202.

[0032] As can be seen from the above working process: through the set box cover 2 and drying mechanism 4, the fan 401 blows the heat generated by the heating wire 402 to all corners inside the box body 1, improving the uniformity of heating of the consumables outside the coil 5, and improving the uniformity and efficiency of drying; at the same time, when the fan 401 malfunctions, pushing the cross plate 405 can drive the positioning block 407 to disengage from the positioning groove 404, completing the disassembly of the fan 401, which is convenient for replacing or repairing the fan 401 and improving the practicality of the device.

[0033] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that the fixing mechanism 6 consists of a motor 601, a rotating cylinder 602, a bidirectional lead screw 604, a slide rod 605, a moving disk 606, a connecting rod 607, a connecting block 608, and an arc-shaped plate 609. The motor 601 is fixedly connected to the middle of the back of the box 1, the rotating cylinder 602 is fixedly connected to the inside of the box 1, the bidirectional lead screw 604 is rotatably connected to the inside of the rotating cylinder 602, and the rear end of the bidirectional lead screw 604 is connected to the output end of the motor 601. The slide rod 605 is symmetrically arranged on the left and right sides of the bidirectional lead screw 604, and the slide rod 605 is fixedly connected to the inside of the rotating cylinder 602.

[0034] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that the movable disk 606 is symmetrically threaded to the outside of the threaded surface of the double-acting screw 604, and the movable disk 606 is slidably connected to the slide rod 605. One end of the connecting rod 607 is symmetrically rotatably connected to the outer surface of the movable disk 606.

[0035] By using the sliding rod 605, the moving disk 606 can be prevented from rotating with the bidirectional lead screw 604, ensuring that the moving disk 606 moves in a straight line and improving the stability of the arc plate 609.

[0036] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that the rotating cylinder 602 has symmetrical slots 603 on its outside. The connecting rod 607 passes through the slot 603. The connecting block 608 is rotatably connected to the other end of the two connecting rods 607 that pass through the same slot 603. The arc plate 609 is fixedly connected to the other end of the connecting block 608, and an anti-slip layer is provided on one side of the arc plate 609.

[0037] The curved plate 609 can increase the fit with the inner wall of the coil 5, and the anti-slip layer can increase the friction between the curved plate 609 and the coil 5, thereby improving the stability of the coil 5.

[0038] This solution has the following working process: In use, first open the cover 201, insert the coil 5 into the inner front of the box 1 until the inner ring of the coil 5 is outside the fixing mechanism 6, then place the coil 5 backwards outside the fixing mechanism 6. Figure 5 As shown, the starter motor 601 drives the bidirectional lead screw 604 to rotate, which in turn drives the two connecting rods 607 to move towards each other via the moving plate 606. The connecting block 608 then drives the arc-shaped plate 609 to move towards the inner ring of the coil 5 until the arc-shaped plate 609 is close to the inside of the coil 5, thus securing the coil 5. Then, the cover 201 is closed. The temperature and humidity sensor 3 and fan 401 are connected to an external controller for control. The temperature and humidity sensor 3 detects the temperature and humidity inside the housing 1. When the humidity reaches the set humidity level... When the heating wire 402 and fan 401 are turned on, the heat generated by the heating wire 402 is blown into the interior of the box 1 through the filter screen 403 to evenly dry the consumables on the coil 5. The heat flows out through the vent 203, cavity 202, and breathable mesh 204, thereby preventing the temperature inside the box 1 from getting too high and improving the practicality of the drying box. At the same time, the temperature and humidity sensor 3 can monitor the temperature inside the box 1 in real time and control the operation of the heating wire 402 to prevent the temperature from getting too high and improve the intelligence of the drying box.

[0039] When the fan 401 malfunctions, the pusher plate 405 presses against the spring 406, moving the positioning block 407 out of the positioning slot 404, releasing the fan 401 from its fixation, allowing the fan 401 to be removed downwards for easy inspection or replacement.

[0040] In summary: Through the lid 2 and drying mechanism 4, the fan 401 blows the heat generated by the heating wire 402 to all corners inside the box 1, improving the uniformity of heating of the consumables outside the coil 5, and enhancing drying uniformity and efficiency; at the same time, when the fan 401 malfunctions, pushing the cross plate 405 can drive the positioning block 407 out of the positioning groove 404, completing the disassembly of the fan 401, facilitating the replacement or repair of the fan 401, and improving the practicality of the device; through the coil 5 and fixing mechanism 6, the extension length of the three arc plates 609 can be adjusted, thereby fixing and installing coils 5 of different diameters before drying, improving the applicability and flexibility of the drying box.
