Description

TECHNICAL FIELD

[0001] The utility model relates to a consumable dryer of bottom end heat source. BACKGROUND

[0002] In 3D printing, every kind of consumable suitable for 3D printer will be more or less damped from air and absorb moisture, and many consumables (such as PLA, ABS, PETG, etc.) are very sensitive to moisture. When printing, these water vapor will rapidly vaporize after being heated in the nozzle with very high temperature, so as to make the consumable melt expand, flow faster and produce pores, and further make the printed part have problems such as stringing, material leakage, holes, rough surface, low strength, etc., and the more serious the consumable is damped (the higher the environmental humidity is, the longer the exposure time is), the more serious these problems are. Therefore, before printing the model, if it is not confirmed that the consumable is dry enough, the consumable needs to be dried first, and the consumable needs to be sealed and dried for protection during use. SUMMARY

[0003] The utility model discloses a consumable dryer of bottom end heat source, which helps to remove moisture in the consumable and prevent problems such as bubbles and stringing in the printing process.

[0004] The technical scheme of the utility model discloses a consumable dryer of bottom end heat source, which comprises a barrel body, a heater is installed on the bottom of the inner cavity of the barrel body, a fan is installed beside the heater, a support frame for supporting a consumable material disc is arranged at the lower part of the inner cavity of the barrel body, a detachable barrel cover is arranged at the upper end of the barrel body, an air outlet hole is arranged on the barrel cover, and a temperature and humidity sensor is installed.

[0005] Further, the barrel body is in an inverted trapezoidal structure, and a sealing ring is arranged on the periphery of the barrel cover and matched with the barrel body.

[0006] Further, the two fans are installed on the both sides of the heater on the bottom of the inner cavity of the barrel body.

[0007] Further, the support frame comprises a pair of light shafts arranged longitudinally on the both sides of the lower part of the barrel body, bearings are arranged at the both ends of the light shafts respectively, and the bearings are installed on the lower side wall of the barrel body.

[0008] Further, the light shafts are aluminum light shafts, and the bearings are deep groove ball bearing.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] 1. The bottom heat source's consumable dryer can effectively remove moisture in the material, prevent bubbles, stringing and other problems during printing. Compared with traditional drying equipment, the design of the bottom heat source usually can use energy more efficiently, reduce energy consumption and improve drying efficiency. The dried consumables can significantly improve the surface quality and strength of the printed products, reducing the printing failures caused by material problems. By drying regularly, it can reduce the performance decline caused by moisture absorption of consumables, thereby prolonging its service life.

[0011] 2. In small or home 3D printing workshops, some materials may need to be dried again after printing to remove residual moisture and ensure the stability of the finished product. The bottom heat source's consumable dryer can provide an efficient consumable processing solution for small batch production. BRIEF DESCRIPTION OF DRAWINGS

[0016] In order to make the above features and advantages of the utility model more obvious and easy to understand, the following examples are given, and the details are described as follows with the help of the drawings, but the utility model is not limited to this.

[0017] REFERENCE Figs. 1 to 3

[0018] A bottom heat source's consumable dryer, comprising a barrel 1, a heater 3 is installed on the base 2 of the inner cavity of the barrel, a fan 4 is installed beside the heater, a support frame 6 for supporting the consumable material tray 5 is arranged at the lower part of the inner cavity of the barrel, a detachable barrel cover 7 is arranged at the upper end of the barrel, an air outlet hole 71 is arranged on the barrel cover, which helps to exhaust the hot air or moisture in the barrel; a temperature and humidity sensor 8 is installed on the bottom surface of the barrel cover.

[0019] In this embodiment, the barrel is in inverted trapezoidal structure, so as to facilitate the loading and unloading of the consumable material tray; a sealing ring is arranged on the periphery of the barrel cover, which helps to improve the sealing performance after the barrel cover is closed.

[0020] In the embodiment, the base of the barrel cavity is provided with a fan on each side of the heater, and the base side of the barrel is provided with an air inlet, which helps the air inlet of the fan. The two fans help to blow the generated heat to each part of the barrel cavity.

[0021] In the embodiment, in order to better support the consumable disc and facilitate the rotation of the consumable disc when taking the material, the support frame includes a pair of light shafts 61 longitudinally arranged on both sides of the lower part of the barrel, and the two ends of the light shafts are respectively provided with bearings 62, which are installed on the lower side wall of the barrel, so that the light shafts can rotate. The vertical consumable disc is placed in the barrel and supported on the pair of light shafts, which helps the consumable disc to rotate when the consumable is pulled out.

[0022] In the embodiment, the light shaft is an aluminum light shaft, and the bearing is a 608 deep groove ball bearing.

[0023] In the embodiment, the temperature and humidity sensor is electrically connected with the heater through the controller, so that after the temperature and humidity sensor detects that the temperature and humidity of the consumable reach the set value, a feedback signal is fed back to the controller, and the controller powers off the heater.

[0024] In use, the consumable is placed on the support frame, the heater 3 is turned on after the barrel cover 7 is closed to heat and dry the consumable, and at the same time the fan 4 also operates to circulate the heat generated by the heater 3 in the barrel to further dry the consumable comprehensively. After a drying time, the temperature and humidity sensor 8 detects whether the temperature and humidity of the consumable meet the standard, and after meeting the standard, the barrel cover 7 can be opened to take the consumable.

[0025] If the utility model discloses or relates to parts or structural members fixedly connected with each other, then, except for another declaration, the fixed connection can be understood as: detachable fixed connection (for example, using bolt or screw connection), and can also be understood as: non-detachable fixed connection (for example, riveting, welding), of course, the fixed connection with each other can also be replaced by an integral structure (for example, manufactured by integral forming process) (except for obviously unable to adopt integral forming process).

[0026] In addition, the terms used to represent the position relationship or shape in any of the above technical solutions disclosed by the utility model include the state or shape similar, similar or close to the above terms, except for another declaration.

[0027] Any component provided by the utility model can be assembled from a plurality of individual components, or can be a single component manufactured by integral forming process.

[0028] The above is only a preferred embodiment of the utility model, and any change and modification made within the scope of the utility model application patent shall be included in the scope of the utility model.
