Description

Technical Field

[0001] This utility model relates to the field of drying technology for printing consumables, specifically a drying device for 3D printing consumables. Background Technology

[0002] 3D printing consumables refer to the materials used in 3D printers. These materials are stacked layer by layer during the 3D printing process to form three-dimensional objects. 3D printing consumables (such as PLA, ABS, etc.) usually need to be kept dry before use because these materials easily absorb moisture from the air, which can lead to problems such as bubbles, streaks, or reduced strength during the printing process. Therefore, they need to be dried with a drying device before use.

[0003] Regarding 3D printing consumable drying devices, a search revealed that CN220447200U discloses a 3D printing consumable drying chamber. The advantages of this utility model are: the insulation module in the 3D printing consumable drying chamber has the advantages of simple structure, low cost, and ease of design and manufacture; furthermore, the insulation module can avoid the bearing mounting seat. In actual use, the 3D printing consumable is fixedly placed inside the drying chamber and cannot be rotated during drying, resulting in uneven heating and slow drying speed. Additionally, the narrow internal space of the drying chamber causes the 3D printing consumable to easily adhere to the inner walls after being placed inside, hindering heat dissipation and contributing to the slow drying speed, thus increasing energy consumption. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a 3D printing consumable drying device. The rotating component can simultaneously drive the 3D printing consumables placed on three trays to rotate, thereby rotating and drying the 3D printing consumables, ensuring uniform heating of the 3D printing consumables, improving the drying speed of the 3D printing consumables, and the supporting component can support and place the roll in a padded position to avoid the roll directly sticking to the tray, which helps the heat to be distributed and flow to dry the 3D printing consumables, thereby accelerating the drying speed of the 3D printing consumables.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] A 3D printing consumable drying device includes: a drying chamber, three trays installed at the bottom of the drying chamber, a limiting rod installed on the top of the three trays, a rotating assembly disposed at the bottom of the drying chamber, the rotating assembly including: an equipment box, a rotary motor, a motor shaft, a large gear, a transmission shaft and a small gear, and a support assembly disposed on the top of the three trays, the support assembly including: an anti-sticking block, an anti-slip block, a through hole and a vent hole.

[0007] Furthermore, an equipment box is fixedly installed at the bottom of the drying oven. A rotary motor is fixedly installed inside the bottom of the equipment box by bolts. The output end of the rotary motor is driven and connected to a motor shaft. A large gear is installed on the motor shaft. Transmission shafts are provided on both sides of the motor shaft.

[0009] Furthermore, a heating box is fixedly installed at the top of the inside of the drying oven, a heating block is fixedly installed inside the heating box by bolts, and a control panel is fixedly installed at the outside of the drying oven by bolts. The control panel is connected to the heating block by wires.

[0010] Furthermore, mounting blocks are fixedly installed on both sides of the inside of the drying oven by bolts, and temperature sensors are fixedly installed on the bottom of each mounting block by bolts. The temperature sensors are connected to the control panel by wires.

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example

[0025] like Figures 1-6 As shown, a 3D printing consumable drying device includes: a drying chamber 1, three trays 101 installed at the bottom of the drying chamber 1, a limiting rod 102 installed at the top of the three trays 101, a rotating assembly set at the bottom of the drying chamber 1, the rotating assembly including: an equipment box 2, a rotary motor 201, a motor shaft 202, a large gear 203, a transmission shaft 204 and a small gear 205, and a support assembly set at the top of the three trays 101, the support assembly including: an anti-sticking block 3, an anti-slip block 301, a through hole 302 and a vent hole 303.

[0026] The drying chamber 1 has a heating chamber 103 fixedly installed at the top inside. A heating block 104 is fixedly installed inside the heating chamber 103 by bolts. A control panel 105 is fixedly installed at the outer end of the drying chamber 1 by bolts. The control panel 105 is connected to the heating block 104 by wires. When using 3D printing consumables, if the 3D printing consumables are damp and affect normal use, they can be placed in the drying chamber 1 for drying. Existing 3D printing consumables are all wound up by a roll. That is, the roll is placed on the tray 101, and the tube hole of the roll is inserted into the limiting rod 102, so that the roll of 3D printing consumables is placed stably on the tray 101. The heating block 104 is started by the control panel 105. The heat generated by the heating block 104 is distributed in the drying chamber 1, which raises the temperature inside the drying chamber 1 and dries the 3D printing consumables, avoiding problems such as bubbles, streaks or reduced strength during the printing process.

[0027] The drying chamber 1 has mounting blocks 106 fixed to both sides inside by bolts. Temperature sensors 107 are fixed to the bottom of each mounting block 106 by bolts. The temperature sensors 107 are connected to the control panel 105 by wires. When the heating block 104 generates heat to dry the inside of the drying chamber 1, the control panel 105 can set the heating temperature of the heating block 104 according to different types of 3D printing consumables to avoid damage to the 3D printing consumables due to excessive temperature. The temperature sensor 107 detects the temperature inside the drying chamber 1 and transmits the detected information to the control panel 105 via an electrical signal. The display screen on the control panel 105 can display the temperature value for easy viewing by the staff.

[0028] The drying oven 1 has an equipment box 2 fixedly installed at its bottom. A rotary motor 201 is bolted to the bottom of the equipment box 2. The output end of the rotary motor 201 is connected to a motor shaft 202. A large gear 203 is mounted on the motor shaft 202. Both sides of the motor shaft 202 have transmission shafts 204, and small gears 205 that mesh with the large gear 203 are mounted on the transmission shafts 204. During the drying process of the 3D printing consumables inside the drying oven 1, the rotary motor 201 and the control panel 105 are connected electrically. The system is connected via a wire and controlled by a control panel 105 to start the rotary motor 201. The rotary motor 201 drives the motor shaft 202 to rotate at a constant speed. The motor shaft 202 drives the large gear 203 to rotate. Since the large gear 203 and the small gear 205 are meshed together, the transmission shaft 204 can rotate synchronously with the motor shaft 202. This allows the 3D printing materials placed on the three trays 101 to rotate simultaneously, thus rotating and drying the 3D printing materials. This ensures that the 3D printing materials are heated evenly and improves the drying speed of the 3D printing materials.

[0029] A rotating hole 206 is provided between the equipment box 2 and the drying box 1. A bearing a207 is installed inside the rotating hole 206. The motor shaft 202 and the transmission shaft 204 pass through the bearing a207 and are connected to the three support plates 101. Support blocks 208 are fixedly installed on both sides of the bottom of the equipment box 2. The bottom end of the transmission shaft 204 is rotatably connected to the support block 208 through the bearing. When in use, the motor shaft 202 and the transmission shaft 204 both protrude from the inside of the drying box 1 through the bearing a207. The top ends of the motor shaft 202 and the transmission shaft 204 are fixedly installed to the three support plates 101 by bolts through connecting blocks. With the support block 208 and the bearing, the transmission shaft 204 can rotate normally and the stability of the rotation of the transmission shaft 204 and the motor shaft 202 can also be ensured.

[0030] The three support plates 101 are equipped with multiple anti-sticking blocks 3 fixedly mounted on their tops. Each anti-sticking block 3 has a toothed anti-slip block 301 mounted on its top. Each anti-sticking block 3 has a through hole 302 on its outer side. The three support plates 101 also have multiple ventilation holes 303 on their tops. When the 3D printing filament roll is on the support plate 101, the bottom end of the roll contacts and adheres to the multiple anti-sticking blocks 3. The anti-sticking blocks 3 support and elevate the roll, facilitating heat dissipation and flow for the 3D printing filament. Drying prevents the 3D printing filament from directly adhering to the tray 101. When the tray 101 is rotated, the anti-slip block 301 with its toothed structure increases the anti-slip properties between the anti-adhesion block 3 and the roll, preventing the roll from sliding and causing left and right swaying, ensuring the roll is placed stably. In addition, the through hole 302 and the vent hole 303 allow the heat inside the drying chamber 1 to be distributed around the tray 101 and the 3D printing filament in the upper, lower, left and right directions, thereby accelerating the drying speed of the 3D printing filament.

[0031] The limiting rod 102 has a limiting block 4 at its top and an insertion hole 401 at its top. The bottom end of the limiting block 4 is fixedly inserted into the insertion hole 401. When the roll is inserted into the limiting rod 102 for limiting placement, the limiting block 4 is fixedly inserted into the insertion hole 401 to prevent the roll from sliding out from the top of the limiting rod 102 during the rotation of the tray 101. When the roll is removed to use 3D printing consumables, the limiting block 4 is grasped and pulled upwards directly to pull it out from the insertion hole 401, making it easy to remove the roll.

[0032] Working principle:

[0033] If the 3D printing consumables become damp and affect normal use, they can be placed in the drying chamber 1 for drying. Existing 3D printing consumables are typically wound up using a roll. The roll is placed on the tray 101, and the limiting rod 102 is inserted into the roll hole to ensure it is securely positioned on the tray 101. The heating block 104 is activated via the control panel 105. The heat generated by the heating block 104 is distributed throughout the drying chamber 1, raising its internal temperature and drying the 3D printing consumables. This prevents problems such as bubbles, streaks, or decreased strength during the printing process.

[0034] During the drying process of the 3D printing consumables inside the drying chamber 1, the rotary motor 201 is connected to the control panel 105 via wires. The control panel 105 controls the rotary motor 201 to start working. The rotary motor 201 drives the motor shaft 202 to rotate at a constant speed. The motor shaft 202 drives the large gear 203 to rotate. Since the large gear 203 and the small gear 205 are meshed, the transmission shaft 204 can rotate synchronously with the motor shaft 202. This simultaneously drives the 3D printing consumables placed on the three trays 101 to rotate and dry the 3D printing consumables, ensuring that the 3D printing consumables are heated evenly and improving the drying speed of the 3D printing consumables.

[0035] When the 3D printing filament roll is on the tray 101, the bottom of the roll is in contact with multiple anti-sticking blocks 3. The anti-sticking blocks 3 support and support the roll, which helps to distribute and flow heat to dry the 3D printing filament and prevents the 3D printing filament from directly sticking to the tray 101. When the tray 101 is rotated, the toothed anti-slip block 301 can increase the anti-slip between the anti-sticking blocks 3 and the roll, preventing the roll from sliding and causing left and right swaying, and ensuring that the roll is placed stably. In addition, the through hole 302 and the vent hole 303 can distribute the heat inside the drying chamber 1 to the tray 101 and the 3D printing filament around it, thereby accelerating the drying speed of the 3D printing filament.
