Description

Technical Field

[0001] This utility model belongs to the field of cooling device technology, specifically relating to a cooling device for an extruder used in the production of 3D printing consumables. Background Technology

[0002] In the production process of 3D printing filaments, the extruder plays a crucial role. It heats and melts the raw materials and extrudes them into filaments of specific shapes. Freshly extruded filaments are hot and soft; if not cooled and shaped promptly, they can deform, have uneven diameters, and severely impact the quality and subsequent performance of the filaments. Currently, most common 3D printing filament extruders use simple air or water cooling systems. While air cooling is simple in structure and low in cost, its cooling efficiency is relatively low, making it difficult to meet the demands of high-speed extrusion production, especially when producing filaments with high dimensional accuracy requirements. Water cooling, on the other hand, has higher cooling efficiency but consumes more water and incurs higher operating costs. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-7 As shown, this utility model provides the following technical solution:

[0028] A cooling device for an extruder used for producing 3D printing consumables includes a guide component 1, a guide space is formed on the guide component 1 to guide the consumables to move along a preset path, and air-cooling components 4 are symmetrically arranged on both sides of the guide component 1, multiple air-cooling components 4 are symmetrically arranged along the preset path, and water-cooling components 3 are also installed on the guide component 1.

[0029] The air-cooled component 4 includes an air guide shroud 41, with an indentation forming a mounting cavity 42 that communicates with the guide space. An air guide fan 43 is installed inside the mounting cavity 42. The water-cooled component 3 includes a mounting base 31 fixedly connected to the material guide component 1. Multiple water distribution trays 32 are fixedly connected to the bottom of the mounting base 31, and a water inlet pipe 33 is fixedly connected to the top of the mounting base 31. The water distribution trays 32 are located inside the guide space and above the consumables. The water inlet pipe 33 is located above the mounting base 31.

[0030] Through the above technical solution, the produced 3D printer consumables are inserted from one side of the guide component 1 and discharged from the other side of the guide component 1, so that the 3D printer consumables are in the guiding space. The water supply pipe is connected to the water inlet pipe 33. The air guide fan 43 inside the air guide shroud 41 works to guide the outside air into the air guide shroud 41. The air guide shroud 41 guides the air to blow onto the 3D printer consumables, thereby cooling the 3D printer consumables. After the water is delivered to the water inlet pipe 33, it is guided to the water distribution tray 32 on the mounting base 31. The water is sprayed out through the water distribution tray 32, so that the water is sprayed onto the 3D printer consumables, thereby further cooling the 3D printer consumables and improving the cooling efficiency of the 3D printer consumables.

[0031] In order to recycle water, such as Figures 1-3 and Figure 6 As shown, a water collecting component 2 is fixedly connected to the bottom of the guide component 1. The water collecting component 2 forms a water storage cavity for storing water. A water conveying part for conveying water is installed between the water collecting component 2 and the water inlet pipe 33. The water conveying part includes a pump body 36. A water pumping pipe 37 and a water outlet pipe 35 are fixedly connected to the water inlet end and the water outlet end of the pump body 36, respectively. The water inlet end of the water pumping pipe 37 is fixedly connected to one side of the water collecting component 2, and the water outlet end of the water outlet pipe 35 is fixedly connected to the water inlet pipe 33.

[0032] In this embodiment, after the water is discharged from the water distribution plate 32, the water is collected in the water storage chamber on the water collection component 2, and the pump body 36 operates so that the water pumping pipe 37 draws water from the water storage chamber and transports it through the water outlet pipe 35, so that the water is transported back to the water inlet pipe 33 and then transported to the water distribution plate 32 through the water inlet pipe 33, thereby reusing the water and improving the water utilization rate.

[0033] To prevent the circulating water from flowing back through inlet pipe 33, such as Figure 1 , Figure 2 and Figure 6 As shown, a one-way valve 34 is fixedly connected to the inlet pipe 33, and the outlet end of the outlet pipe 35 is located at the liquid outlet end of the one-way valve 34. When water is transported to the inlet pipe 33 through the outlet pipe 35, the one-way valve 34 is used to prevent the water from flowing back, thereby improving the water flow efficiency.

[0034] Specifically, in one embodiment, regarding the aforementioned water collection element 2, as... Figures 1-3 and Figure 5 As shown, the water collection component 2 includes a water collection box 21, a water guide frame 27 is fixedly connected between the top of the water collection box 21 and the bottom of the guide component 1, and the liquid inlet end of the pumping pipe 37 is fixedly connected to one side of the water collection box 21.

[0035] In this embodiment, after the water is discharged from the water distribution plate 32, the water is guided by the water guide frame 27 and transported to the water collection box 21 for water collection.

[0036] When water is recycled, in order to improve the heat dissipation efficiency of the water, such as Figures 1-5 As shown, multiple heat-conducting plates 22 are fixedly connected inside the water collection box 21, and multiple heat-conducting holes 23 are formed by recesses on the multiple heat-conducting plates 22. Multiple heat dissipation plates 26 are fixedly connected outside the water collection box 21.

[0037] In this embodiment, when water enters the water collection box 21, it absorbs heat through the heat-conducting plate 22 and heat-conducting hole 23, and improves the heat dissipation efficiency of the water inside the water collection box 21 through the heat dissipation plate 26 on the outside of the water collection box 21.

[0038] When personnel need to drain the water from the water collection box 21, in order to facilitate the drainage of the water, such as Figure 3 and Figure 5 As shown, a drain pipe 24 is fixedly connected to the bottom of the water collection box 21. A valve 25 is installed on the drain pipe 24. When water needs to be discharged, the valve 25 on the drain pipe 24 is opened, so that the water inside the water collection box 21 can be discharged through the drain pipe 24.

[0039] When the gas guide shroud 41 guides the gas, in order to filter the gas, such as Figures 1-3 and Figure 7 As shown, a filter screen 44 is installed on the side of the air guide hood 41 away from the material guide 1. Before the gas enters the air guide hood 41, the gas is filtered by the filter screen 44 to remove dust from the gas.

[0040] Specifically, in one embodiment, regarding the aforementioned guide member 1, as... Figures 1-4 As shown, the material guide 1 includes a material guide frame 11. Both sides of the material guide frame 11 are recessed to form air guide grooves 17. An air guide cover 41 is fixedly connected to the material guide frame 11 and communicates with the air guide grooves 17. Two material guide holes 16 are symmetrically opened on the material guide frame 11. Multiple air guide grooves 17 are located between the two material guide holes 16, and a downwardly inclined water guide plate 18 is fixedly connected inside the air guide grooves 17.

[0041] In this embodiment, the 3D printing consumables that need to be cooled are inserted into one guide hole 16 and discharged from another guide hole 16. The mounting base 31 is supported by the guide frame 11, and water is sprayed out through the water distribution plate 32 to spray and cool the 3D printing consumables. The water guide plate 18 is used to prevent the water from flowing into the air guide groove 17.

[0042] To make the movement of consumables smoother, such as Figures 1-4 As shown, the guide frame 11 has two first brackets 12 and two second brackets 14 fixedly connected to one side near the two guide holes 16. The feed rollers 13 are rotatably connected inside the two first brackets 12, and the discharge rollers 15 are rotatably connected inside the two second brackets 14.

[0043] In this embodiment, when the 3D printing filament moves between the two guide holes 16, the feed roller 13 is supported by the first bracket 12 and the output roller 15 is supported by the second bracket 14. The rotation of the feed roller 13 and the output roller 15 makes the movement of the 3D printing filament smoother.

[0044] After the water flows into the guide frame 11, in order to concentrate the water for discharge and prevent water from leaking out from the two guide holes 16, such as Figure 4 As shown, two liquid guiding slopes 19 are formed inside the guide frame 11, and the horizontal height of the liquid guiding slope 19 on the side closer to the guide hole 16 is higher than the horizontal height of the other side.

[0045] In this embodiment, when the water flows into the inside of the guide rack 11, it is guided by the liquid guide slope 19 to flow to the middle position of the bottom of the guide rack 11, making it easier to collect the water.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
