Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of consumable pretreatment, and particularly relates to an intelligent 3D printing consumable drying box and a consumable pretreatment method. BACKGROUND

[0002] There are three main methods for existing 3D printing consumable drying processing. First, hot air drying method, which dries the consumables by heating and circulating air flow, although simple operation, but the efficiency is limited by the rate of air flow; second, vacuum drying method, which places the consumables in a vacuum environment, and accelerates the evaporation of moisture by reducing the pressure, although it can effectively remove moisture, but the equipment cost is high, the operation is complex, and it is not conducive to large-scale application; finally, using moisture-absorbing materials such as silica gel to absorb moisture in the air, which is low in cost, but slow in drying speed and limited in effect.

[0003] In terms of machine automation, the current 3D printing consumable drying box generally has low automation degree. In terms of consumable humidity detection, although some 3D printing drying boxes (for example, CN117532882A) can detect the humidity of the air inside the drying box, they cannot directly monitor the humidity state of the consumables, which makes users need to rely on experience to judge whether the consumables are suitable for 3D printing. Since such devices cannot determine whether the water content of the consumables is within a usable range, the consumables may not be of good quality, and directly using consumables of poor quality may cause the printer to be unusable or fail, resulting in unnecessary consumption of consumables. In terms of consumable weight monitoring, most existing 3D printing drying boxes (for example, CN112229182A) lack consumable quality monitoring function and cannot remind users to replace the consumables, which may cause 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 each time, which is very inconvenient. In terms of energy consumption, although the existing 3D printing consumable drying box (for example, US20230090184) has a timing drying function, in order to ensure the drying quality, the user usually sets the drying time much longer than the time required to reach the humidity target, resulting in unnecessary energy consumption. In terms of water vapor balance, the existing 3D printing drying box (for example, CN219360336U) often cannot automatically remove water vapor, and the user needs to manually open the door to exhaust, which increases the user's operation burden, and in addition, due to the instability of the external air humidity, it may not be able to ensure the reduction of the humidity in the box. In addition, in order to adapt to consumables of different diameters, the discharge port is designed to be large, which also makes it easy for water vapor to enter, further reducing the drying effect.

[0004] Therefore, the prior art still needs to be improved and developed. SUMMARY

[0005] In view of the deficiencies of the prior art described above, the purpose of the present application is to provide an intelligent 3D printing consumable drying box and a consumable pretreatment method, aiming to solve the problems of poor drying effect and low degree of intelligence of the existing 3D printing consumable drying box.

DETAILED DESCRIPTION

[0034] The present application provides an intelligent 3D printing consumable drying box and a consumable pretreatment method. To make the purpose, technical solutions and effects of the present application clearer and more explicit, the present application is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0035] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. In addition, the terms "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include one or more of the features.

[0036] Those skilled in the art can understand that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as generally understood by those skilled in the art to which the present application belongs. It should also be understood that terms such as those defined in a general dictionary should be understood as having meanings consistent with those in the context of the prior art, and unless specifically defined as such, should not be interpreted in an idealized or overly formal sense.

[0037] In 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. Since most 3D printing consumables have strong hygroscopicity, if appropriate storage measures are not taken, the consumables are easy 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 decreases, quality problems such as faults, bubbles, etc. may occur during the printing process, which seriously affects the printing accuracy and the overall performance of the product. Therefore, the drying process of 3D printing consumables has become an important link to ensure the printing quality and has important significance for improving the printing effect and the quality of the finished product.

[0038] However, the existing 3D printing consumable drying box has problems such as uneven drying, substandard drying, low automation, low energy efficiency, and poor water vapor balance.

[0039] Based on this, as shown in the Figures 1-3 The present application provides an intelligent 3D printing consumable drying box, comprising:

[0040] A housing 10 is provided with a receiving space 11 and a display module 14;

[0041] A drying module 20 is arranged in the receiving space 11;

[0042] A tray module 30 includes a weighing sensor 31 arranged at the bottom of the receiving space 11, a tray drum tray 32 arranged on the weighing sensor 31, and a tray 33 arranged on the tray drum tray 32; The tray 33 is provided with an RFID tag 331;

[0043] A data acquisition module 40 includes an electronic device support plate 41 arranged in the receiving space 11, and an RFID card reader 42, a temperature and humidity sensor 43, and a mainboard 44 arranged on the electronic device support plate 41;

[0044] A dehumidification and condensation module 50 is embedded on one side of the drying module 30.

[0045] 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 mainboard calculates the water content of the consumables according to the monitoring results of the temperature and humidity during the drying process, and controls the dehumidification and condensation module 50 to work, so as to condense the water vapor in the air into water and automatically discharge it, and ensure that the air humidity in the drying box is maintained at a low level. At the same time, the RFID tag 331 and the RFID card reader 42 are introduced to realize automatic identification and reading of the consumable information, so that the user can easily obtain the data such as the suitable drying temperature, water content control target and spool weight of the consumables, and send a replacement reminder when the remaining consumable quality is lower than the set value, thereby improving the intelligent and automatic level of the drying box.

[0046] Specifically, the RFID card reader 42 is used to scan the RFID tag pre-recorded with the consumable information and the corresponding suitable drying temperature, water content control target and spool weight data, so as to realize automatic identification and reading of the consumable information, thereby improving the intelligent and automatic level of the drying box. The data acquisition module can obtain the water content of the consumables, so as to ensure that the water content of the consumables in the equipment is within a usable range, thereby ensuring the subsequent printing quality. In addition, the high-precision weighing sensor can monitor the remaining amount of the consumables in real time and send a replacement or jam reminder to the user in time. In addition, the water content of the consumables can be calculated according to the air humidity change rate monitored by the temperature and humidity sensor. Compared with the air humidity in the box, the water content of the consumables can more directly and accurately reflect the printing quality of the consumables. In addition, the intelligent 3D printing consumable drying box of the present application has a small footprint and is convenient to place near the 3D printer.

[0047] Further, the total weight of the tray 33 and the consumables is obtained by the weighing sensor 31, and the weight of the current consumables can be obtained by combining the weight of the tray obtained by the RFID card reader 42. When the weight of the consumables is lower than the set value, the drying box will send a reminder information to the user to remind the user to replace the consumables, thereby reducing the risk of printing failure caused by material breakage. In addition, if it is found that the quality of the consumables has not changed for a long time during the printing process, a fault reminder will be sent to the user. In addition, the current water content of the consumables can be calculated by 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 card reader.

[0048] In some embodiments, the reading of the consumable parameters is realized by the RFID card reader, and can be completed by common identification methods including but not limited to camera recognition, NFC, etc.

[0049] In some embodiments, as Figure 3As shown, the shell 10 comprises an upper shell 12 and a lower shell 13, the upper shell 12 and the lower shell 13 enclose the receiving space 11, and the upper shell 12 and the lower shell 13 are movably connected; the upper shell 12 is provided with a discharge port. Preferably, the discharge port is provided with an elastic rubber plug 121.

[0050] Specifically, the upper shell 12 and the lower shell 13 are provided with a hinge connector, the upper shell 12 can be opened by rotating through the hinge connector, and the structure that the upper shell 12 and the lower shell 13 enclose the receiving space 11 can tightly seal the tray 33, and in combination with the elastic rubber plug 121 of the discharge port, 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 drying environment in the drying box.

[0051] In some embodiments, as shown in Figure 4 and Figure 5 As shown, the drying module 20 comprises a C-shaped air duct 21, an air inlet fan 22 and an air outlet fan 23 arranged at both ends of the air duct 21, and an electric heater 24 arranged in the air duct 21 close to one end of the air outlet fan 23; the tray module 30 is arranged between the air inlet fan 22 and the air outlet fan 23. The combination of the electric heater 24 and the air inlet fan 22 and the air outlet fan 23 can improve the drying efficiency and drying effect. The air inlet fan 22 and the air outlet fan 23 promote the air flow in the receiving space 11, so that the heated gas can heat the consumables more quickly and uniformly.

[0052] Specifically, the drying module 20 comprises a C-shaped air duct 21, an air inlet fan 22 and an air outlet fan 23 arranged at both ends of the air duct 21, and an electric heater 24 arranged in the air duct 21 close to one end of the air outlet fan 23; the tray module 30 is arranged between the air inlet fan 22 and the air outlet fan 23. The combination of the electric heater 24 and the air inlet fan 22 and the air outlet fan 23 can improve the drying efficiency and drying effect. The air inlet fan 22 and the air outlet fan 23 promote the air flow in the receiving space 11, so that the heated gas can heat the consumables more quickly and uniformly.

[0053] In the present embodiment, the drying module adopts a hot air drying mode to discharge the moisture present in the consumables; in another embodiment, the drying module can also include, but is not limited to, a reduced air pressure and microwave drying mode to facilitate the discharge of moisture in the consumables. The electric heating wire in the electric heater 24 can be replaced by a PI heating sheet, a PTC heating sheet, or other modules capable of generating heat.

[0054] In some embodiments, the air duct 21 is provided with a condensing duct 25 at one end close to the air inlet fan 22, the condensing duct 25 is in communication with the air duct 21; the dehumidifying and condensing module 50 is embedded in the condensing duct 25. During the operation of the drying module, the current moisture content of the consumables is calculated and displayed simultaneously, and when the moisture content of the consumables 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 yes, the dehumidifying and condensing module 50 is controlled to work to reduce the air humidity inside the dryer.

[0055] In some embodiments, the electronic device support plate 41 is arranged on the outer wall of the air duct 21 and adjacent to the condensing duct 25. The integration of the internal structure of the drying box is improved, and the volume of the drying box is saved.

[0056] In some embodiments, the tray roller tray 32 includes a support plate 321, a first roller 322 and a second roller 323 arranged at both ends of the support plate 321, respectively; the outer edge of the tray 33 is in rolling connection with the first roller 322 and the second roller 323. By arranging the first roller 322 and the second roller 323 at both ends of the support plate 321, the tray 33 can smoothly roll, and the weighing sensor 31 can accurately measure the weight of the tray. Of course, it can also be achieved by including, but not limited to, adding a support cylinder to the middle of the tray and other common printing consumable placement methods.

[0057] Specifically, using the tray roller tray 32 can reduce the activity friction between the tray and the bottom support when the tray is discharged, which can reduce the risk of jamming and improve the printing success rate.

[0058] In some embodiments, the housing 10 is provided with a display module 14, and the display module 14 is connected to the main board 44 through a wire to be powered on. The display module displays the parameters such as the type of consumables, the target temperature and humidity, the real-time cabin temperature and humidity, the target moisture content of the consumables, the current moisture content of the consumables, and the remaining weight of the consumables, and interacts with the user to set the target temperature and humidity and the heating time, which can be achieved by including, but not limited to, an OLED display screen, an LCD display screen, a dot matrix screen, a physical pointer, a key, and other common display interaction modules.

[0059] In this embodiment, the OLED display screen is used as the display module 14 to display the consumable type, target temperature and humidity, real-time temperature and humidity in the cabin, target moisture content of the consumable, current moisture content of the consumable and remaining weight of the consumable in real time, so that the user can know the state of the consumable and compare the remaining weight of the consumable with the required consumable weight of the printed product to more accurately quantify the feasibility of printing. At the same time, the OLED display screen provides operation buttons for starting drying, adjusting the target temperature and humidity and the target moisture content of the consumable, etc., so that the user can customize the working state and working parameters of the device.

[0060] In some embodiments, as shown in Figure 6 The dehumidification and condensation module 50 includes a condensation end 51, a heat dissipation end 52, a refrigeration fin 53 arranged between the condensation end 51 and the heat dissipation end 52, and a heat dissipation fan 54 arranged on the side of the heat dissipation end 52 away from the refrigeration fin 53. The condensation end 51 is embedded in the drying module 20, and the heat dissipation end 52 is arranged on the outside of the shell 10.

[0061] Specifically, the temperature and humidity sensor 43 is used to monitor the temperature and humidity of the air in the drying cabinet. The purpose of obtaining the temperature is to enable the drying cabinet to control the temperature at the appropriate drying temperature of the current consumable. When the humidity of the air in the drying cabinet is too high, the mainboard 44 controls the electric heater 24 to stop working, and the dehumidification and condensation module 50, the air inlet fan 22 and the air outlet fan 23 work to condense the water vapor in the air into water at the condensation end 51, and automatically discharge the water out of the drying cabinet through the drain port, thereby ensuring a low air humidity in the drying cabinet and improving the drying effect. Preferably, the refrigeration fin is a semiconductor refrigeration fin, which can complete the condensation of water vapor in high-humidity gas in the cabin, and other common condensation methods can also be used.

[0062] In some embodiments, the dehumidification and condensation module 50 further includes a water collecting tank 55 arranged corresponding to the condensation end 51, and the shell 10 is provided with a drain port 15. The water in the water collecting tank 55 is discharged through the drain port 15.

[0063] Specifically, the water collecting tank 55 is arranged in the air duct 21 corresponding to the condensation end 51, and the water collecting tank 55 is provided with the same drain port 15 as the drain port 15. The water droplets condensed by the condensation end 51 fall into the water collecting tank 55 and are discharged out of the drying cabinet through the through hole and the drain port.

[0064] In some embodiments, the lower shell 13 is provided with a dehumidification and condensation module installation cavity 16 corresponding to the dehumidification and condensation module 50, for installing the dehumidification and condensation module 50. Specifically, the refrigeration sheet 53 is embedded on the shell wall of the lower shell 13, the condensation end is located in the condensation channel 25, and the heat dissipation end 52 is located in the dehumidification and condensation module installation cavity 16. The dehumidification and condensation module installation cavity 16 is provided with an opening near one side of the heat dissipation fan 54 for heat exchange of the heat dissipation fan.

[0065] In some embodiments, the drainage port 15 is provided with a one-way liquid guide film, so that the water condensed in the device can be smoothly discharged; at the same time, the temperature and humidity sensor arranged in the drying box monitors the temperature and humidity of the air in real time, and the main board controls the dehumidification and condensation module according to the monitoring result to condense the water vapor in the air into water and automatically discharge it through the one-way liquid guide film, so as to ensure that the air humidity in the drying box is maintained at a low level.

[0066] In a preferred embodiment, a waterproof and breathable EPTFE film is used to balance the air pressure inside and outside the cabin, while isolating the water vapor in the external air.

[0067] In some embodiments, the intelligent 3D printing consumable drying box further comprises a 3D printer device interaction module for information interaction between the intelligent 3D printing consumable drying box and the 3D printer.

[0068] Specifically, by comparing the remaining amount of consumables and the amount of consumables consumed by 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 the user is fed back how many hours after printing the refilling needs to be performed when it is determined that the printing task cannot be completed. In addition, the interaction between the drying box and the 3D printing device can also realize the function of printing error reporting.

[0069] In addition to the display module, the intelligent 3D printing consumable drying box of the present embodiment can also develop towards cloud control, providing users with a more convenient control method for the consumable drying box.

[0070] In addition, the present application also provides a consumable preprocessing method based on an intelligent 3D printing consumable drying box, comprising the steps of:

[0071] Step S10: placing a tray with rolled consumables into the intelligent 3D printing consumable drying box, and rotating the tray so that the RFID reader obtains the information of the RFID tag on the tray;

[0072] Step S20: after the total mass of the consumables is read by the weighing sensor and the temperature and humidity of the inside of the intelligent 3D printing consumable drying box are read by the temperature and humidity sensor, the drying module starts to work and obtains the moisture content of the consumables, and it is determined whether the moisture content of the consumables reaches a usable value.

[0073] Step S30: If the moisture content of the consumables reaches the available value, determine whether the humidity inside the intelligent 3D printing consumables drying box needs to be condensed, and complete the pretreatment of the consumables.

[0074] In some embodiments, the 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 mainboard controls the operation of the dehumidification and condensation module 50 according to the monitoring results, condenses the water vapor in the air into water and automatically discharges it, and ensures 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 card reader 42 are introduced to realize automatic identification and reading of consumable information, facilitate users to obtain data such as suitable drying temperature, moisture content control target and wire reel weight of consumables, and issue a replacement reminder when the remaining consumable quality is lower than the set value, thereby improving the intelligence and automation level of the drying box.

[0075] Specifically, the flowchart of the consumable pretreatment method based on the intelligent 3D printing consumables drying box is as follows: Figure 7When the user puts the reel of wire into the smart 3D printing material drying box, the user needs to rotate the reel so that the RFID card reader can read the information about the material, and then close the upper shell. Then, the smart 3D printing material drying box will automatically read the total weight of the material, the temperature and humidity of the gas inside the drying box, and display the obtained information such as the type of material, the target moisture content, the current temperature and humidity, and the total weight of the material on the OLED display screen. Then, the user manually clicks the start drying button on the OLED display screen, and the smart 3D printing material drying box will automatically perform the following processes in sequence: the inlet fan, the outlet fan and the electric heater start working to dry the material, and the current moisture content of the material is calculated and displayed. When the moisture content of the material is lower than the set target, the electric heater will stop working. Then, it is judged whether the air humidity inside the drying box is higher than the set target. If it is higher, the dehumidification and condensation module is controlled to work. When the air humidity inside the drying box is lower than the set target, the dehumidification and condensation module and the fan stop working. When the moisture content of the material is higher than the set target, it is judged whether the air humidity inside the drying box is higher than the set target. If it is higher, the electric heater is controlled to stop working and the dehumidification and condensation module is controlled to work. If the air humidity is lower than the set target, the inlet fan, the outlet fan and the electric heater continue to work. Further, according to the air humidity change rate monitored by the temperature and humidity sensor, the moisture content of the material is calculated, the state of the material and the drying condition are accurately judged, and whether to continue drying is controlled by comparing the moisture content of the material and the target moisture content of the material, so as to reduce unnecessary drying time consumption. At the same time, the drying and condensation alternating operation mode is adopted. Drying will evaporate the water in the material into water vapor, and through condensation, the water vapor in the high humidity gas in the cabin is liquefied, the humidity of the air in the cabin is reduced, and the drying efficiency is improved.
