Description

Technical Field

[0001] The utility model relates to the technical field of consumable pretreatment, in particular to an intelligent 3D printing consumable drying oven. Background Art

[0002] There are mainly three mainstream methods for the current drying treatment of 3D printing consumables. First is the hot air drying method, which dries the consumables by heating and circulating air. Although the operation is simple, the efficiency is limited by the rate of air circulation. Second is the vacuum drying method, which places the consumables in a vacuum environment and accelerates water evaporation by reducing the pressure. Although it can effectively remove moisture, the equipment cost is high, the operation is complex, and it is not conducive to large-scale application. Finally, hygroscopic materials such as silica gel are used to absorb moisture in the air. The cost is low, but the drying speed is slow and the effect is limited.

[0003] In terms of machine automation, the current degree of automation of 3D printing consumable drying ovens is generally low. In terms of consumable humidity detection, although some 3D printing drying ovens (such as CN117532882A) can detect the humidity of the air inside the drying oven, they cannot directly monitor the humidity state of the consumables. This requires users to rely on experience to judge whether the consumables are suitable for 3D printing. Since such devices cannot determine whether the moisture content of the consumables is within the usable range, the quality of the consumables may be poor. Directly using poor-quality consumables may cause the printer to become unusable or printing to fail, resulting in unnecessary consumption of consumables. In terms of consumable weight monitoring, most of the existing 3D printing drying ovens (such as CN112229182A) lack the function of monitoring the quality of consumables and cannot send a reminder to the user to change the material, which may lead to printing interruption due to insufficient consumables. In addition, the material type, set drying temperature and humidity, etc. on the display screen need to be manually set by the user every time, which is very inconvenient. In terms of energy consumption, although the existing 3D printing consumable drying ovens (such as US20230090184) have a timed drying function, to ensure the drying quality, users usually set the drying time much longer than the time actually required to reach the humidity target, resulting in unnecessary energy consumption. In terms of water vapor balance, existing 3D printing drying ovens (such as CN219360336U) often cannot automatically remove water vapor, and users need to manually open the door of the oven for exhaust, which increases the operation burden of the user. In addition, due to the unstable humidity of the outside air, it may not be possible to ensure that the humidity inside the oven is reduced. In addition, in order to adapt to consumables with different wire diameters, the outlet is designed to be relatively large, which also makes it easy for water vapor to enter, further reducing the drying effect.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Utility Model

Detailed implementation manners

[0030] The present utility model provides an intelligent 3D printing consumable drying box. To make the purpose, technical solutions and effects of the present utility model clearer and more definite, the present utility model is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0031] In the description of the present application, it should be understood that the orientation or positional relationships indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features.

[0032] Those skilled in the art can understand that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as the general understanding of those of ordinary skill in the field to which this utility model belongs. It should also be understood that terms such as those defined in a general dictionary should be understood to have a meaning consistent with their meaning in the context of the prior art, and will not be interpreted with an idealized or overly formal meaning unless specifically defined as here.

[0033] During the 3D printing process, the quality of the consumables is one of the decisive factors to ensure the printing effect and the quality of the finished product. Given that most 3D printing consumables have strong hygroscopicity, if appropriate storage measures are not taken, the consumables are likely to absorb moisture in the air, thereby causing changes in their physical properties, such as viscosity, fluidity, etc., which will directly reduce the quality of the consumables. When the quality of the consumables deteriorates, quality problems such as faults and bubbles may occur during the printing process, seriously affecting the printing accuracy and the overall performance of the product. Therefore, the drying treatment of 3D printing consumables has become an essential and important link to ensure the printing quality, and is of great significance for improving the printing effect and the quality of the finished product.

[0034] However, existing 3D printing consumable drying ovens have problems such as uneven drying, unqualified drying, low automation level, low energy efficiency, and poor water vapor balance.

[0035] Based on this, as Figures 1 - 3 shown, this utility model provides an intelligent 3D printing consumable drying oven, including:

[0036] A housing 10, the housing 10 is provided with a receiving space 11 and a display module 14;

[0037] A drying module 20, arranged in the receiving space 11;

[0038] A tray module 30, including a weighing sensor 31 arranged at the bottom of the receiving space 11, a tray roller tray 32 arranged on the weighing sensor 31, and a tray 33 arranged on the tray roller tray 32; an RFID tag 331 is provided on the tray 33;

[0039] A data acquisition module 40, including an electronic device support plate 41 arranged in the receiving space 11, and an RFID reader 42, a temperature and humidity sensor 43, and a main board 44 arranged on the electronic device support plate 41;

[0040] A dehumidification and condensation module 50, embedded on one side of the drying module 30.

[0041] In this embodiment, the drying module 30 is used to dry the consumables, and the temperature and humidity sensor 43 is used to monitor the temperature and humidity of the air in real time. The main board calculates the moisture content of the consumables according to the temperature and humidity monitoring results during the drying process, and controls the dehumidification and condensation module 50 to work, condensing the water vapor in the air into water and automatically discharging it to ensure that the air humidity inside the drying box is maintained at a low level. At the same time, the RFID tag 331 and the RFID reader 42 are introduced to realize the automatic identification and reading of the consumable information, which is convenient for users to obtain data such as the appropriate drying temperature, moisture content control target, and spool weight of the consumables, and issue a material replacement reminder when the remaining mass of the consumables is lower than the set value, improving the intelligence and automation level of the drying box.

[0042] Specifically, the RFID reader 42 is used to scan the RFID tag pre-recorded with the consumable information and the corresponding data such as the appropriate drying temperature, moisture content control target, and spool weight, realizing the automatic identification and reading of the consumable information, and improving the intelligence and automation level of the drying box. The data acquisition module can be used to obtain the moisture content of the consumables, ensuring that the moisture content of the consumables in the device is within the available range and guaranteeing the subsequent printing quality. Moreover, the high-precision weighing sensor monitors the remaining amount of the consumables in real time and timely issues reminders such as material replacement or jamming to the user. In addition, the moisture content of the consumables is calculated based on the rate of change of the air humidity monitored by the temperature and humidity sensor. Compared with the air humidity inside the box, the moisture content of the consumables can more directly and accurately reflect the printing quality of the consumables. And, the intelligent 3D printing consumable drying box of the present utility model occupies a small area and is convenient to be placed near the 3D printer.

[0043] Furthermore, in this embodiment, the weighing sensor 31 is used to obtain the total weight of the spool 33 and the consumables. Combining with the spool weight obtained by the RFID reader 42, the weight of the current consumables can be known. When the weight of the consumables is lower than the set value, the drying box will send a reminder message to the user to remind the user to replace the material, reducing the risk of printing failure caused by material shortage. And, during the printing process, if it is found that the quality of the consumables has not changed for a long time, a fault reminder will be sent to the user. In addition, combining the dynamic change rate of the humidity, the temperature during the change process, and the weight information of the consumables obtained by the weighing sensor and the RFID reader, the current moisture content of the consumables can be calculated.

[0044] In some embodiments, the reading of the consumable parameters is realized through the RFID reader, and it can be completed by common identification methods including but not limited to camera recognition, NFC, etc.

[0045] In some embodiments, such as Figure 3As shown, the housing 10 includes an upper housing 12 and a lower housing 13. The upper housing 12 and the lower housing 13 enclose the receiving space 11, and the upper housing 12 is movably connected to the lower housing 13. An outlet is provided on the upper housing 12. Preferably, an elastic rubber plug 121 is provided at the outlet.

[0046] Specifically, hinge connectors are provided on the upper housing 12 and the lower housing 13. By using the hinge connectors, the upper housing 12 can be opened by rotation. And with the structure that the upper housing 12 and the lower housing 13 enclose the receiving space 11, the material tray 33 can be tightly sealed. At the same time, combined with the elastic rubber plug 121 at the outlet, it is ensured that the internal environment of the drying box is isolated from the external environment during the discharging process, effectively preventing moisture from entering and maintaining the stability of the dry environment inside the drying box.

[0047] In some embodiments, as Figure 4 and Figure 5 shown, the drying module 20 includes a C-shaped air duct 21, an inlet fan 22 and an outlet fan 23 provided at both ends of the air duct 21, and an electric heater 24 provided at one end of the air duct 21 close to the outlet fan 23. The material tray module 30 is arranged between the inlet fan 22 and the outlet fan 23. By using the combination of the electric heater 24, the inlet fan 22 and the outlet fan 23 to dry the consumables, the drying efficiency and drying effect can be improved. The inlet fan 22 and the outlet fan 23 promote the air flow in the receiving space 11, so that the heating gas can heat the consumables more quickly and evenly.

[0048] Specifically, the present utility model uses the combination of the inlet fan 22, the outlet fan 23 and the electric heater 24 to dry the consumables inside the device. Among them, the electric heater 24 uses an electric heating wire to heat the air in the intelligent 3D printing consumable drying box. When the moisture content of the consumables is too high, the inlet fan 22 and the outlet fan 23 jointly promote the air flow inside the drying box, so that the gas heated by the electric heater can heat the consumables more quickly and evenly, and the moisture in the consumables enters the air. Further, the air that absorbs the moisture in the consumables enters the air duct 21 through the inlet fan 22, and successively passes through the dehumidification and condensation module 50 and the electric heater 24. During the drying process, the dehumidification and condensation module does not work, and the electric heater works intermittently, completing the heating of the air and keeping the gas temperature in the device constant. Finally, the heated air is discharged outside the air duct 21 by the outlet fan 23 and enters the device interior.

[0049] In this embodiment, the drying module adopts the method of hot air drying to discharge the moisture present in the consumables; in another embodiment, the drying module may also include, but is not limited to, methods such as reducing air pressure and microwave drying to promote the discharge of moisture in the consumables. The heating wire in the electric heater 24 can be replaced with modules capable of generating heat, such as PI heating sheets and PTC heating sheets.

[0050] In some embodiments, a condensation channel 25 is provided at one end of the air duct 21 close to the inlet fan 22, and the condensation channel 25 communicates with the air duct 21; the dehumidification and condensation module 50 is embedded at the condensation channel 25. During the operation of the drying module, the moisture content of the current consumable is calculated and displayed at the same time. When the moisture content of the consumable is lower than the set target, the electric heating device stops working; then, it is judged whether the air humidity inside the dryer is higher than the set target. If it is higher, the dehumidification and condensation module 50 is controlled to work to reduce the air humidity inside the dryer.

[0051] In some embodiments, the electronic device support plate 41 is arranged on the outer wall of the air duct 21 and is adjacent to the condensation channel 25. This improves the integration of the internal structure of the drying box and saves the volume of the drying box.

[0052] In some embodiments, the tray drum tray 32 includes a support plate 321, a first drum 322 and a second drum 323 respectively arranged at both ends of the support plate 321; the outer edge of the tray 33 is in rolling connection with the first drum 322 and the second drum 323. By arranging the first drum 322 and the second drum 323 at both ends of the support plate 321, the tray 33 can roll smoothly, and the weighing sensor 31 can accurately measure the weight of the tray. Of course, it can also be realized by common consumable placement methods during printing, including but not limited to adding a support cylinder in the middle of the tray.

[0053] Specifically, using the tray drum tray 32 can reduce the moving friction between the tray and the bottom support during discharging, reduce the risk of material jamming, and thus improve the printing success rate.

[0054] In some embodiments, a display module 14 is provided on the housing 10, and the display module 14 is connected and powered on by a wire to the main board 44. This display module displays parameters such as the type of consumables, target temperature and humidity, real-time temperature and humidity inside the chamber, target moisture content of the consumable, current moisture content of the consumable, and remaining weight of the consumable to the user, and interacts with the self-setting of target temperature and humidity and heating time. It can be realized by common display and interaction modules including but not limited to OLED displays, LCD displays, dot matrix screens, physical pointers, and buttons.

[0055] In this embodiment, an OLED display screen is used as the display module 14 to display in real time the types of consumables, the target temperature and humidity, the real-time temperature and humidity inside the chamber, the target moisture content of the consumables, the current moisture content of the consumables, and the remaining weight of the consumables, so that the user can know the status of the consumables and can compare the remaining weight of the consumables with the required weight of the consumables for the printed parts to more accurately quantify the feasibility of printing. At the same time, operation buttons such as start drying, adjust target temperature and humidity, and target moisture content of consumables are provided on the OLED display screen, so that the user can customize and adjust the working state and working parameters of the device of the present invention.

[0056] In some embodiments, as Figure 6 shown, the dehumidification and condensation module 50 includes a condensation end 51, a heat dissipation end 52, a thermoelectric cooler 53 disposed between the condensation end 51 and the heat dissipation end 52, and a cooling fan 54 disposed on the side of the heat dissipation end 52 away from the thermoelectric cooler 53; the condensation end 51 is embedded in the drying module 20, and the heat dissipation end 52 is disposed outside the housing 10.

[0057] Specifically, the temperature and humidity sensor 43 is used to monitor the temperature and humidity of the air inside the drying oven. The purpose of obtaining the temperature is to enable the drying oven to control the temperature at the appropriate drying temperature of the current consumables. The purpose of obtaining the humidity is that when it is detected that the air humidity inside the drying oven is too high, the main board 44 will control the electric heater 24 to stop working, and the dehumidification and condensation module 50, the inlet fan 22, and the outlet fan 23 will work to condense the water vapor in the air into water at the condensation end 51 and automatically discharge it from the drying oven through the drain port, ensuring a lower air humidity inside the drying oven and improving the drying effect. Preferably, the thermoelectric cooler is a semiconductor thermoelectric cooler, which can complete the condensation of water vapor in the high-humidity gas inside the chamber and can be achieved by other common condensation methods.

[0058] In some embodiments, the dehumidification and condensation module 50 further includes a water collection tank 55 corresponding to the condensation end 51, and the housing 10 is provided with a drain port 15; the water in the water collection tank 55 is discharged through the drain port 15.

[0059] Specifically, the water collection tank 55 is disposed in the air duct 21, corresponding to the condensation end 51, and the water collection tank 55 is provided with a drain port 15 identical to the drain port 15. The water droplets formed by the condensation of the condensation end 51 fall into the water collection tank 55 and are discharged from the drying oven through the through hole and the drain port.

[0060] In some embodiments, a dehumidification and condensation module placement cavity 16 is provided at the position corresponding to the dehumidification and condensation module 50 on the lower housing 13 for placing the dehumidification and condensation module 50. Specifically, the thermoelectric cooler 53 is embedded in the wall of the lower housing 13, the condensation end is located in the condensation channel 25, the heat dissipation end 52 is located in the dehumidification and condensation module placement cavity 16, and an opening is provided on one side of the dehumidification and condensation module placement cavity 16 close to the cooling fan 54 for heat exchange by the cooling fan.

[0061] In some embodiments, a one-way liquid guiding film is provided at the drain port 15 to enable the moisture obtained by condensation in the device to be discharged smoothly; at the same time, a temperature and humidity sensor provided inside the drying box monitors the temperature and humidity of the air in real time, and the main board controls the operation of the dehumidification and condensation module according to the monitoring results, condenses the water vapor in the air into water and automatically discharges it through the one-way liquid guiding film to ensure that a relatively low air humidity is maintained inside the drying box.

[0062] In a preferred embodiment, a waterproof and breathable EPTFE film is used to balance the air pressure inside and outside the cabin and at the same time isolate the water vapor in the outside air.

[0063] In some embodiments, the intelligent 3D printing consumable drying box further includes a 3D printer device interaction module for information interaction between the intelligent 3D printing consumable drying box and the 3D printer.

[0064] Specifically, by comparing the remaining amount of the consumables and the amount of consumables required for the printing task, it is determined whether the remaining consumables are sufficient to complete the printing task, and then the result of whether the task can be completed is directly fed back to the user, and when it is determined that the printing task cannot be completed, the user is fed back how many hours after printing the material needs to be replaced. In addition, functions such as printing error reporting can also be realized through the interaction between the drying box and the 3D printing device.

[0065] In addition to the display module, the interaction between the intelligent 3D printing consumable drying box of this embodiment and the user can also develop towards cloud control, providing a more convenient control method for the user for the consumable drying box.

[0066] In addition, the present invention also provides a method for preprocessing consumables based on an intelligent 3D printing consumable drying box, including the steps of:

[0067] Step S10: Place the reel with the consumables into the intelligent 3D printing consumable drying box, and rotate the reel so that the RFID reader obtains the information of the RFID tag on the reel.

[0068] Step S20: After the weighing sensor reads the total mass of the consumables and the temperature and humidity sensor reads the temperature and humidity inside the intelligent 3D printing consumables drying oven, the drying module starts to work and obtains the moisture content of the consumables, and determines whether the moisture content of the consumables reaches the available value;

[0069] Step S30: If the moisture content of the consumables reaches the available value, then determine whether the humidity inside the intelligent 3D printing consumables drying oven needs to be condensed to complete the pretreatment of the consumables.

[0070] In some embodiments, this consumable pretreatment method uses the drying module 30 to dry the consumables, and uses the temperature and humidity sensor 43 to monitor the temperature and humidity of the air in real time. The main board controls the dehumidification and condensation module 50 to work according to the monitoring results, condenses the water vapor in the air into water and automatically discharges it to ensure that the air humidity inside the drying oven is maintained at a low level; at the same time, the RFID tag 331 and the RFID reader 42 are introduced to realize the automatic identification and reading of the consumable information, which is convenient for users to obtain data such as the appropriate drying temperature, moisture content control target and spool weight of the consumables, and send a material replacement reminder when the remaining mass of the consumables is lower than the set value, improving the intelligence and automation level of the drying oven.

[0071] Specifically, the flow schematic diagram of the consumable pretreatment method based on the intelligent 3D printing consumables drying oven is as Figure 7As shown, when the user puts the coil with the consumables rewound into the intelligent 3D printing consumable drying oven, the user needs to rotate the coil so that the RFID card reader can read the relevant information of the consumables, and then close the upper housing. Then, the intelligent 3D printing consumable drying oven will automatically read the total weight of the consumables, the temperature and humidity of the gas inside the drying oven, and display the information such as the type of consumables, the target moisture content, the current temperature and humidity, and the total weight of the consumables on the OLED display screen. After that, the user manually clicks the start drying button on the OLED display screen, and the intelligent 3D printing consumable drying oven will automatically perform the following processes in sequence: the inlet fan, the outlet fan, and the electric heater start to work to dry the consumables, and at the same time calculate and display the moisture content of the current consumables. When the moisture content of the consumables is lower than the set target, the electric heater will stop working. After that, it is judged whether the air humidity inside the drying oven is higher than the set target. If it is higher, the dehumidification and condensation module will be controlled to work. When the air humidity inside the drying oven is lower than the set target, the dehumidification and condensation module and the fan will stop working. When the moisture content of the consumables is higher than the set target, it is judged whether the air humidity inside the drying oven is higher than the set target. If it is higher, the electric heater will be controlled to stop working and the dehumidification and condensation module will work. If the air humidity is lower than the set target, the inlet fan, the outlet fan, and the electric heater will continue to work. Further, in this embodiment, the moisture content of the consumables is calculated based on the change rate of the air humidity monitored by the temperature and humidity sensor, the state and drying condition of the consumables are accurately judged, and whether to continue drying is controlled by comparing the moisture content of the consumables with the target moisture content of the consumables, so as to reduce the consumption of unnecessary drying time. At the same time, a mode of alternating operation of drying and condensation is adopted. Drying will evaporate the moisture in the consumables into water vapor, and the water vapor in the high-humidity gas in the chamber will be liquefied through condensation to reduce the humidity of the air in the chamber, thereby improving the drying efficiency.
