[0002] 3D printing is a type of rapid prototyping technology. Specifically, it is a technology that uses digital model files as the basis, 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. The consumables used by 3D printers are mostly line reel-type consumables, which are easy to absorb water in the air. The water vapor boils during the printing and melting heating, affecting the molding quality of the workpiece, so the consumables need to be dried.
[0003] The existing consumables drying method is mainly to place desiccant in a closed space, which absorbs moisture from the air, reduces air humidity, and avoids the impact of air humidity on printing consumables. However, this method takes a long time to dry, cannot accelerate the volatilization and absorption of water vapor in the air, and the use effect is not ideal. Therefore, how to accelerate the volatilization and absorption of water vapor in the air and achieve rapid drying of consumables is an urgent problem to be solved. Utility Model Content
[0004] The present application provides a drying device, a consumables box and a 3D printer to solve the problem of how to accelerate the volatilization and absorption of water vapor in the air to achieve rapid drying of consumables.
[0005] In order to solve the above technical problems, the present application provides a drying device, comprising:
[0006] A frame, the frame comprising an air outlet, an air inlet and a drying chamber, the drying chamber being connected to the air outlet and the air inlet;
[0007] a heating assembly, the heating assembly being configured to be disposed near the air outlet;

[0010] As a further improvement of the present application, the blowing assembly is arranged in the lower chamber, and the air outlet is opened on the side wall of the lower chamber close to the heating assembly, so that the blowing assembly blows the gas in the upper chamber from the air outlet to the heating assembly.

[0012] A plurality of the drying chambers are arranged adjacent to each other, and each drying chamber is provided with a corresponding heating component and a blowing component.
[0013] As a further improvement of the present application, the heating component is a heating film, and the blowing component is a fan.
[0014] The present application also provides a consumables box, comprising a shell and any one of the above-mentioned drying devices, wherein the shell comprises a shell base and an arc-shaped cover body disposed above the shell base, and one end of the arc-shaped cover body is hinged to the shell base;
[0015] The surface of one side of the arc-shaped cover body away from the blowing assembly is an arc-shaped protrusion, so that the gas heated by the heating assembly can rise along the arc guide of the arc-shaped cover body.
[0016] As a further improvement of the present application, a self-circulating gas drying channel is formed in the shell, and the gas drying channel includes at least a first drying channel extending from the gas outlet toward the heating component, a second drying channel extending upward from the heating component along the arc-shaped cover body, and any one of the third drying channels extending from the top of the arc-shaped cover body toward the drying chamber.

[0034] In order to make the description of the disclosed content more detailed and complete, the following is an illustrative description of the implementation methods and specific embodiments of the present application; however, this is not the only form of implementing or using the specific embodiments of the present application. The implementation methods cover the features of multiple specific embodiments and the method steps and sequences used to construct and operate these specific embodiments. However, other specific embodiments can also be used to achieve the same or equivalent functions and step sequences.
[0035] Please refer to Figure 1-Figure 7 In order to solve the problem of how to accelerate the volatilization and absorption of water vapor in the air and achieve rapid drying of consumables in the prior art, the present application embodiment provides a drying device, a consumable box and a 3D printer. Please refer to Figure 1, is a structural schematic diagram of a drying device provided in an embodiment of the present application, the drying device includes a frame, a heating component 20 and an air blowing component 30, wherein the frame includes an air outlet 52, an air inlet 51, and a drying chamber 40 connected to the above-mentioned air outlet 52 and the air inlet 51. The present application sets the heating component 20 at a position close to the air outlet 52, and the air blowing component 30 is configured to blow the gas in the drying chamber 40 out of the air outlet 52, and the consumables are dried by the heating component 20, the air blowing component 30 and the drying material filled in the drying chamber 40.
[0036] In the embodiment of the present application, the heating component 20 is arranged at a position close to the air outlet 52, and the dry gas in the drying chamber 40 is blown out through the air outlet 52 by the blower component 30. At this time, the heating component 20 heats the blown gas, and the gas begins to rise after being heated and heated, and becomes humid gas after absorbing water molecules in the air. Due to factors such as temperature drop or weight increase, the humid gas enters the drying chamber 40, and the drying material filled in the drying chamber 40 dries the humid gas. The dried gas is then blown out from the air outlet 52 by the blower component 30, thereby forming a self-circulating gas drying channel.
[0037] It should be noted that the heating component 20 provided in the present application can be set not only on the side of the frame close to the air outlet 52, but also on the side of the frame close to the air outlet 52. Since the consumable tray 14 is usually large in size, the consumable tray 14 needs to be set outside the frame; and in order to achieve a better drying effect on the consumables, the present application preferably sets the heating component 20 on the side of the frame close to the air outlet 52, and sets the consumable tray 14 above the heating component 20. At this time, the heating component 20 can not only properly heat the gas around the consumable tray 14, but also increase the temperature of the consumables, evaporate the moisture in the consumables, reduce the water content of the consumables, and achieve rapid drying of the consumables.
[0038] Of course, it is also feasible to arrange the heating component 20 on a side of the frame close to the air outlet 52. This arrangement can also achieve the effect of drying the consumables. In this embodiment, the blowing component 30 blows the dry gas in the drying chamber 40 directly to the heating component 20 for heating, and the air outlet 52 blows out the gas that has been heated and heated. At this time, the gas that begins to rise after heating and heating can also achieve the effect of drying the consumables.
[0039] Obviously, whether the heating component 20 is set on a side of the frame close to the air outlet 52 or on a side of the frame close to the air outlet 52, the consumables can be dried. The present application does not impose any further restrictions on the specific setting position of the heating component 20, as long as its setting position is capable of heating the gas blown out by the blowing component 30.
[0040] The present application preferably sets the heating component 20 on a side outside the frame close to the air outlet 52 to achieve heating of the gas while heating the gas around the consumable material disk 14. The following explanation of the present application will also be described based on setting the heating component 20 on a side outside the frame close to the air outlet 52, but this does not serve as a limitation on the specific setting position of the heating component 20 of the present application, and technical personnel in this field should be aware of this.
[0041] As an optional implementation, please refer to Figure 5 , is a structural schematic diagram of the air inlet 51 in the drying device provided in an embodiment of the present application. In a specific embodiment provided in the present application, the above-mentioned drying chamber 40 includes an upper chamber 41 and a lower chamber 42 which are interconnected up and down, wherein the upper chamber 41 is provided with a first side wall 411 inclined upward, and a plurality of drying holes 412 are provided on the first side wall 411, so that the rising gas after heating can enter the upper chamber 41 through the drying holes 412 provided on the first side wall 411. Since the upper chamber 41 is configured to be filled with drying material, the gas entering the upper chamber 41 is dried under the action of the drying material. At the same time, the inclined upward structure also facilitates the gas that becomes moist after absorbing water molecules to enter the upper chamber 41.
[0042] Specifically, the drying material filled in the upper chamber 41 refers to a substance that can remove moisture from the humid gas, such as commonly used chemical desiccants such as calcium sulfate and calcium chloride, which dry by combining with water to form hydrates, or commonly used physical desiccants such as silica gel and activated alumina, which dry by physically adsorbing water; as long as it can adsorb moisture from the humid gas entering the upper chamber 41, any selected drying material is feasible, and multiple drying materials can also be mixed for use. The present application does not further explain the specific setting form of the drying material.
[0043] In order to better utilize the internal space of the drying chamber 40, please refer to Figure 4 , is a schematic diagram of the structure of the air blast assembly 30 in the drying device provided in an embodiment of the present application. The present application sets the air blast assembly 30 in the lower chamber 42. Since the upper chamber 41 and the lower chamber 42 are interconnected, the present application sets the air inlet 51 at the connecting portion between the air blast assembly 30 and the upper chamber 41, and sets the air outlet 52 on the side of the lower chamber 42 close to the heating assembly 20, so that the air that has been dried in the upper chamber 41 is drawn into the lower chamber 42 from the air inlet 51 through the air blast assembly 30, and then blown toward the heating assembly 20 through the air outlet 52, and the blown air is heated by the heating assembly 20.
[0044] It should be noted that, although the present application sets the blowing assembly 30 in the lower chamber 42, its actual blowing flow direction will not blow to the drying material filled in the upper chamber 41, affecting the drying of the humid gas by the drying material. In a specific embodiment, the drying material can be set in the form of a drying bag.
[0045] Since in actual applications, the number of consumable discs 14 used inside the shell 10 is more than one, and a corresponding heating component 20, a blowing component 30 and a drying chamber 40 need to be set for each consumable disc 14, the number of heating components 20, blowing components 30 and drying chambers 40 provided in the embodiment of the present application is at least one, and it is necessary to set heating components 20, blowing components 30 and drying chambers 40 that are no less than the number of consumable discs 14, so as to dry several consumable discs 14 at the same time.
[0046] Since several consumable material trays 14 are arranged adjacent to each other, several drying chambers 40 also need to be arranged adjacent to each other corresponding to the positions of the several consumable material trays 14. At the same time, several heating components 20 and blowing components 30 also need to be arranged one by one with the drying chambers 40 at the corresponding positions. Therefore, the present application does not make any specific restrictions on the number of heating components 20, blowing components 30 and drying chambers 40.
[0047] In a specific embodiment provided in the present application, the above-mentioned blowing component 30 can be set as a fan or as other exhaust equipment, such as an exhaust pump; the above-mentioned heating component 20 can be set as an electric heating wire or as other heating components, such as a heating film. As long as it can achieve heating of the gas, any selected heating component 20 is feasible, and the present application does not impose further restrictions on this.
[0048] Based on the above-mentioned drying device, the present application also provides a consumable box, which includes a shell 10 and the above-mentioned drying device. The present application uses the shell 10 to form a closed space to prevent external humid air from entering the consumable box and affecting the consumable tray 14 placed inside.
[0049] Specifically, the housing 10 includes a housing base 11 and an arc-shaped cover 12 disposed above the housing base 11. Figure 7 , is a structural schematic diagram of the arc-shaped cover body 12 in the drying device provided in an embodiment of the present application. It can be observed that the bottom of the arc-shaped cover body 12 is hinged to the shell base 11 through a hinge 15 and a hinge shaft 16. Of course, in actual applications, the arc-shaped cover body 12 and the shell base 11 can also be hinged through other structures, and the present application does not make further restrictions on this.
[0050] A magnetic part 17 is provided at the position where the top of the arc-shaped cover body 12 is connected to the shell base 11. Specifically, the magnetic part 17 can be set in the form of a magnetic sheet, so that the shell base 11 can be quickly fixed and adsorbed by the magnetic part 17. The outer wall of the arc-shaped cover body 12 is provided with an inwardly recessed handle 18. The arc-shaped cover body 12 can be quickly opened and closed by pulling up the handle 18 and cooperating with the magnetic attraction of the magnetic part 17, so that the working status of each component inside the shell 10 can be checked conveniently.
[0051] As an optional embodiment, the present application sets the frame on one side of the shell 10 to form a cavity for accommodating the blowing assembly 30 and the drying chamber 40 with the side wall of the shell 10, and sets the heating assembly 20 outside the frame but inside the shell 10 and close to the air outlet 52, and sets the consumable material tray 14 above the heating assembly 20. Since the blowing assembly 30 blows air from the air outlet 52 to the position above the heating assembly 20, dry hot air is generated above the heating assembly 20. After the dry hot air rises, it absorbs water molecules in the air to become humid gas, and then enters the drying chamber 40 to complete drying.
[0052] Furthermore, the present application sets the side surface of the arc cover body 12 away from the blowing assembly 30 as an arc-shaped protrusion, so that the gas heated by the heating assembly 20 rises along the arc-shaped guide of the arc-shaped protrusion, and thus a self-circulating gas drying channel is formed inside the shell 10, and the gas drying channel at least includes a first drying channel extending from the air outlet 52 toward the heating assembly 20, a second drying channel extending upward from the heating assembly 20 along the arc-shaped guide of the arc-shaped cover body 12, and a third drying channel extending from the top of the arc-shaped cover body 12 toward the drying chamber 40.
[0053] It should be noted that the gas drying channel provided in the present application includes at least any one of the above-mentioned first drying channel, second drying channel and third drying channel. In principle, gas drying needs to pass through the first drying channel, the second drying channel and the third drying channel, but it does not exclude that the gas directly enters the third drying channel through the first drying channel, or directly enters the third drying channel through the second drying channel, or directly enters the drying chamber 40 from the third drying channel to achieve drying.
[0054] In the embodiments of this application, please refer to Figure 2, which is a three-dimensional assembly diagram of the drying device provided in an embodiment of the present application. It can be observed that at least two consumable holders 13 are rotatably installed on the inner side wall of the shell 10. The two consumable holders 13 are arranged in parallel so that the consumable disk 14 wrapped with consumables is set above the heating component 20, so that the consumables wrapped on the consumable disk 14 are dried through the cooperation of the blowing component 30, the heating component 20 and the drying chamber 40. At the same time, the consumable disk 14 can rotate on the two consumable holders 13 to meet the needs of feeding and withdrawing consumables; at the same time, the inclination degree of the first side wall 411 of the drying chamber 40 should be adapted to the self-rotation direction of the consumable disk 14, but the distance cannot be too close to affect the normal rotation of the consumable disk 14.
[0055] When several consumable material trays 14 are arranged inside the shell 10, two consumable material brackets 13 need to be correspondingly arranged at the bottom of each consumable material tray 14. Therefore, the present application provides a consumable support plate 19 for supporting the consumable brackets 13 at the bottom of two adjacent consumable material trays 14; taking two consumable material trays 14 as an example, at this time, one end of the consumable bracket 13 arranged at the bottom is rotatably mounted on the inner wall of the shell 10, and the other end of the consumable bracket 13 is rotatably mounted on the consumable support plate 19; taking three consumable material trays 14 as an example, at this time, one end of the consumable bracket 13 arranged at the bottom of the consumable material trays 14 on the left and right sides is rotatably mounted on the inner wall of the shell 10, and the other end of the consumable bracket 13 is rotatably mounted on the consumable support plate 19, and both ends of the consumable bracket 13 arranged at the bottom of the middle consumable material tray 14 are rotatably mounted on the consumable support plate 19, and so on.
[0056] For further information, please refer to Figure 2 and Figure 7 , also includes a display panel 54 and an inspection window 57 arranged on the outer wall of the shell 10. The present application also provides a control mainboard 53 inside the shell 10. The control mainboard 53 is arranged corresponding to the inspection window 57. The control mainboard 53 can be repaired or adjusted by opening the inspection window 57. At the same time, the control mainboard 53 is connected to the above-mentioned heating component 20, the blowing component 30 and the display panel 54 by wired or wireless means. The control mainboard 53 is used to control the working status of the heating component 20 and the blowing component 30. The display panel 54 displays the working status of each electrical component in the shell 10 in real time. Of course, the control mainboard 53 can also be connected to other electrical components in the shell 10 that need power supply or control. The present application will not go into details here.
[0057] Furthermore, a power interface 58 connected to the control mainboard 53 is also provided at the bottom of the shell 10 , and the power interface 58 is used to access an external power source. At the same time, a power switch 59 is also provided on the power interface 58 to control the power usage status inside the shell 10 .
[0058] As an optional implementation, in order to realize the free combination application of multiple drying devices, if it is necessary to realize the simultaneous printing of several consumable material trays 14, please refer to Figure 6 , is a structural schematic diagram of the docking female head 56 in the drying device provided in an embodiment of the present application. In the present application, a docking male head 55 and a docking female head 56 are correspondingly arranged on the outer side wall of the shell 10. By plugging the docking male head 55 of the current shell 10 with the docking female head 56 of another shell 10, and / or plugging the docking female head 56 of the current shell 10 with the docking male head 55 of another shell 10, the arrangement and plugging requirements of multiple shells 10 are met.
[0059] Based on the above-mentioned drying device, the present application also provides a 3D printer, including the consumable box provided in the above-mentioned embodiment. Since the consumables wound on the consumable material disk 14 need to be applied during the 3D printing process, and the dryness of the consumables during the printing process needs to be ensured, the consumable box provided by the present application can be used on the basis of a conventional 3D printer to achieve rapid drying of the printing consumables used in the 3D printer, thereby improving the quality of the finished product of 3D printing.
[0060] Compared with the prior art, the drying device, consumable box and 3D printer provided in the embodiments of the present application accelerate the convection of the gas in the shell by arranging a self-circulating gas drying channel in the shell, and cooperating with the heating component, the blowing component and the drying chamber. Since the gas inside the shell is continuously blown to the top of the heating component by the blowing component, the dried hot air rises along the arc of the arc-shaped cover body, and the humid gas after absorbing water molecules in the air descends into the drying chamber due to factors such as temperature drop or weight increase, and the humid gas is dried by the desiccant filled in the drying chamber; the blowing component continuously blows air to the top of the heating component through the air outlet, which accelerates the circulation and drying of the gas inside the shell and greatly shortens the drying time; at the same time, the consumable material tray wrapped with consumables is arranged above the heating component, so the heating component will also increase the temperature of the consumables, evaporate the moisture in the consumables, reduce the water content of the consumables, and achieve rapid drying of the printing consumables, ensuring the final 3D printing effect.
[0061] It can be understood that the technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0062] The above embodiments are merely exemplary embodiments used to illustrate the principles of the present application, but the present application is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of the present application, and these modifications and improvements are also considered to be within the scope of protection of the present application.
