Abstract
Description
Technical Field
[0001] The utility model relates to the technical field, in particular to a moisture-proof storage device for FDM printing consumables. Background Art
[0002] With the rapid development of science and technology, especially the progress in the field of additive manufacturing (AM), the sales volume of domestic 3D printers has achieved a significant explosive growth. Among the many 3D printing technologies, Fused Deposition Modeling (FDM) has become one of the most popular printing processes due to its relatively low cost and ease of use. However, although FDM technology has a dominant position in the market, the technical challenges it faces cannot be ignored.
[0003] FDM technology mainly relies on polymer thermoplastic materials as consumables, which are usually wound on reels in the form of lines for users to use. However, due to the moisture-absorbing properties of polymer thermoplastic materials, when the reel is directly exposed to the air, the consumables can easily absorb moisture from the air, resulting in an increase in the water molecule content. This problem is particularly prominent during the printing process, because during the heating process of the consumables, the water molecules adsorbed inside will boil and produce bubbles, which not only affects the appearance and strength of the printed object, but may even cause the material to become brittle, thereby causing printing failure.
[0004] In addition, some special polymer thermoplastic materials, such as PEek and PPS, have a high cost, which increases the printing cost accordingly. These materials often need to be preheated at a constant temperature before printing, and need to be maintained at an optimal temperature during the printing process to obtain better printing results.
[0005] In summary, although FDM technology has broad application prospects in the field of 3D printing, the problems it faces, such as the easy moisture absorption of polymer thermoplastic materials, the high cost of special materials, and printing temperature control, are still key factors restricting its further development. Therefore, finding an effective solution to deal with these problems has become a technical challenge that needs to be solved in the development of FDM technology. To this end, we propose a moisture-proof storage device for FDM printing consumables. Utility Model Content

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figure 1-5 The utility model provides a technical solution: a moisture-proof storage device for FDM printing consumables, comprising a storage shell 1 for storing consumables, a constant temperature system 2 is arranged inside the storage shell 1, and the constant temperature system 2 comprises an airflow circulation system 3 and a temperature detection system 4, wherein the temperature detection system 4 detects the internal temperature of the storage shell 1, and when the temperature is lower than a preset threshold value, the airflow circulation system 3 regulates the internal temperature of the storage shell 1.
[0028] The temperature detection system 4 includes a temperature sensor 5 and a humidity sensor 6, both of which are respectively arranged inside the storage shell 1 and detect the temperature and humidity of the storage area for placing consumables.
[0029] This solution includes a control main board 7, which is installed inside the storage shell 1. The control board is used to receive data from the temperature and humidity sensor 6, and judge the temperature and humidity inside the storage shell 1 by analyzing the data. When the temperature and humidity change, the airflow circulation system 3 is controlled to start working.
[0030] The temperature detection system 4 monitors the temperature and humidity inside the storage shell 1 in real time through the temperature sensor 5 and the humidity sensor 6. When the temperature is lower than the preset threshold, the air circulation system 3 starts to work to regulate the internal temperature.
[0031] The air flow circulation system 3 includes an air duct 8 installed in the storage shell 1, on which an air outlet pipe 9 and an air inlet pipe 10 are respectively arranged, and the ends of the three are interconnected. One end of the air outlet pipe 9 and the air inlet pipe 10 are connected to the outside of the storage shell 1, and the other end is connected to the inside of the storage shell 1. Opening and closing components 11 are respectively installed at the ports of the air inlet pipe 10 and the air outlet pipe 9 close to the outside of the storage shell 1, and an opening and closing component 11 is also arranged on the air duct 8 between the air outlet pipe 9 and the air inlet pipe 10. The opening and closing component 11 is used to block the air flow between the air ducts 8.
[0032] The air circulation system 3 is composed of an air duct 8, an air outlet pipe 9, an air inlet pipe 10 and a fan assembly 15. The fan assembly 15 drives the air to circulate between the inside and outside of the storage shell 1;
[0033] In order to more conveniently explain the constant temperature principle, the opening and closing components 11 are now divided into the opening and closing components 11 located at the end of the air inlet pipe 10, between the air outlet pipe 9 and the air inlet pipe 10, and at the end of the air outlet pipe 9, respectively named as the first opening and closing component 110, the second opening and closing component 111, and the third opening and closing component 112;
[0034] External circulation mode: The first and third opening and closing components 112 are opened, and the second opening and closing component 111 is closed, forming an external circulation. At this time, the external air enters the device through the air inlet pipe, and most of the water vapor is filtered out by the air filter plate 16. At the same time, the PTC heater heats and dries the incoming air to ensure that the air entering the device is dry. Subsequently, the dry air is blown into the storage shell 1 through the fan component 15, and the internal water vapor is taken out from the air outlet pipe 9 to achieve the drying of the internal environment.
[0035] The opening and closing assembly 11 includes a sealing plate 12 , one end of which is connected to a propulsion member 13 for controlling the movement of the sealing plate 12 , and the propulsion member 13 is an electromagnet 14 .
[0036] In the present device, the electromagnet 14 is cleverly designed and mounted on the housing. The housing not only serves to fix the electromagnet 14, but also provides precise guidance for the sealing plate 12. This guidance design ensures the stability and accuracy of the sealing plate 12 during movement.
[0037] The specific structure is that the electromagnet 14 is installed at a specific position of the shell, and a slide groove or guide rail is provided inside the shell to match the sealing plate 12. The ejector rod is slidably connected with the shell through these slide grooves or guide rails, so as to realize its linear movement under the action of the electromagnet 14.
[0038] When the electromagnet 14 is energized, a strong magnetic field is generated inside the electromagnet 14. This magnetic field attracts one end of the sealing plate 12, so that the sealing plate 12 is attracted toward the electromagnet 14. Due to the guiding effect of the shell, the sealing plate 12 can move smoothly along the preset track until it contacts the electromagnet or reaches a predetermined position.
[0039] This design makes full use of the magnetism of the electromagnet and the principle of mechanical transmission to achieve rapid and accurate movement of the sealing plate 12. At the same time, the guiding effect of the shell also ensures the stability and reliability of the sealing plate 12 during movement, thereby improving the working efficiency and safety of the entire device.
[0040] Since the above structure is a conventional design by those skilled in the art, it is not convenient to elaborate on it again.
[0041] The electromagnet 14 is electrically connected to the control main board 7 and is controlled by the control main board 7. In addition, the electromagnet 14 is installed on the lane. The electromagnet 14 receives a command from the control main board 7 to drive the sealing plate 12 to move.
[0042] The ends of the air inlet pipe 10 and the air outlet pipe 9 close to the inside of the storage shell 1 are both provided with a fan assembly 15. The fan assembly 15 adopts an existing structure, which will not be described in detail here.
[0043] A heater for heating the air is installed at the port of the air inlet pipe 10 close to the inside of the storage shell 1. The heater is a PCT heater, which can heat the air.
[0044] An air filter plate 16 is installed at the port of the air inlet duct close to the outside of the storage shell 1. The air filter plate 16 can filter the outside air to a certain extent to prevent the outside dust from entering the inside of the storage shell.
[0045] The storage shell 1 is made of glass fiber reinforced polyphenylene sulfide, which to a certain extent avoids heat exchange between the air inside the storage shell 1 and the outside, thereby preventing energy loss.
[0046] A flame retardant heat sink 17 is installed inside the storage shell 1, and the air discharged through the air inlet pipe 10 enters the area where the consumables are stored through the flame retardant heat sink 17. By providing the flame retardant heat sink, it is possible to prevent the heated air from being too hot, which may damage the consumables.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0048] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
