Description

Technical Field

[0001] The utility model relates to a heat preservation device, in particular to a heat preservation device of a conveyor belt type 3D printer, belonging to the technical field of 3D printing. Background Art

[0002] In the field of 3D printing technology, temperature control during the printing process is one of the key factors that determine printing quality and efficiency. Different types of printing consumables have different shrinkage properties. If there is a lack of effective insulation measures for the printed material, when the material is cooled from high temperature to room temperature, the shrinkage of the material will cause warping. Especially when printing large models, the material is heated to a molten state and then quickly solidified. The rapid temperature change will cause thermal stress, which will cause the print to warp, crack, and even lead to the risk of printing failure.

[0003] Conveyor belt 3D printers are different from traditional 3D printers in that they can print infinitely in the Z-axis direction. In order to adapt to this type of conveyor belt 3D printer, a matching insulation device needs to be made to ensure the stability of printing. However, due to material limitations, the insulation devices of existing conveyor belt 3D printers cannot be well adjusted to the use area during use. When placing and insulating printers of different models, it is often necessary to replace insulation devices of different models for operation, which also limits the maximum size of the printed object.

[0004] Therefore, those skilled in the art provide a heat preservation device for a conveyor belt 3D printer to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0028] 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.

[0029] See also Figures 1 to 6 The embodiment of the utility model provides a heat preservation device for a conveyor belt type 3D printer, comprising: a lower box body 1, an adjustment mechanism 2 and a frame assembly 3.

[0030] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 6 The lower box body 1 includes a cloth layer 101, a pearl cotton layer 102 and an insulating aluminum foil layer 103. A fixedly connected corrugated sheet 11 is installed on the top of the lower box body 1, and a fixedly connected upper box body 12 is installed on the top of the corrugated sheet 11. The outer side of the frame assembly 3 is sleeved with a thermal insulation aluminum foil layer 103, and the outer side of the thermal insulation aluminum foil layer 103 is bonded with the pearl cotton layer 102 by glue, and the outer side of the pearl cotton layer 102 is bonded with the cloth layer 101 by glue. The lower box body 1, the corrugated sheet 11 and the upper box body 12 are made of the same material. A discharge port 15 is provided on the right side of the lower box body 1, and a rotatably connected cover plate 16 is installed on the right side of the lower box body 1 and located outside the discharge port 15 through a hinge. Magnetic strips 14 for magnetic connection are installed on the right side of the lower box body 1 and the left side of the cover plate 16. A movably connected inspection cover 17 is installed on the left side of the lower box body 1 through a zipper, and a through hole 13 is provided on the front surface of the lower box body 1.

[0031] It should be noted that: when the 3D printer is insulated, the pearl cotton layer 102 has good thermal insulation performance, effectively blocking the invasion of external cold air and the dissipation of internal heat. The thermal insulation aluminum foil layer 103 has excellent thermal conductivity and thermal insulation, and can quickly balance and permanently maintain the temperature distribution in the printing area, preventing printing quality problems caused by uneven heat, and effectively suppressing the model warping problem caused by temperature changes during the printing process, thereby significantly improving the appearance quality and internal performance of the 3D printed parts. Only the 3D printer needs to be placed in the box, and the inspection cover 17 can be closed by zipper to quickly form a stable insulation environment, which greatly simplifies the installation and disassembly process of the insulation device, reduces the user's operating burden, and improves the convenience of the equipment. When using a conveyor belt 3D printer to print long-axis objects, the conveyor belt direction can be smoothly extended through the magnetic strip 14, the discharge port 15 and the cover plate 16, without being limited by the volume of the device, ensuring that the printed object can extend completely and unhindered along the conveyor belt direction, which not only retains the good insulation effect of the printing area, but also greatly expands the size range of 3D printing.

[0032] In the embodiments of the present invention, please refer to Figure 3 and Figure 4 The adjusting mechanism 2 is located on the back side of the lower box body 1, and the adjusting mechanism 2 includes a supporting plate 21, a threaded rod 22, a fixing plate 23, a screw sleeve 24, a connecting plate 25, an adjusting rod 26 and an adjusting plate 27. The bottom of the back side of the lower box body 1 is fixedly mounted with a supporting plate 21 by fastening screws, the top of the back side of the lower box body 1 is fixedly mounted with a fixing plate 23 by fastening screws, and the back side of the upper box body 12 is fixedly mounted with an adjusting plate 27 by fastening screws. A threaded rod 22 rotatably connected is installed between the supporting plate 21 and the fixing plate 23 through a bearing, and a screw sleeve 24 movably connected is installed on the surface of the threaded rod 22 through a thread, and the screw sleeve 27 is fixedly mounted with a screw sleeve 24. The left and right sides of the support plate 21 are both equipped with welded connecting plates 25, the top of the connecting plate 25 is equipped with a welded adjusting rod 26, the top of the adjusting rod 26 penetrates the inner surface of the fixing plate 23 and is welded to the bottom of the adjusting plate 27, the adjusting mechanism 2 also includes a handwheel 20, the bottom of the support plate 21 is movably connected with the handwheel 20 for driving the threaded rod 22 to rotate through a bearing, the top of the handwheel 20 is fixedly connected to the bottom of the threaded rod 22, the adjusting mechanism 2 also includes a slide seat 28 and a slider 29, the left and right sides of the support plate 21 are both equipped with welded slide seats 28, and the left and right sides of the connecting plate 25 are both equipped with sliders 29 slidably connected to the inner cavity of the slide seat 28.

[0033] It should be noted that when it is necessary to expand the usable area, first turn the handwheel 20, and the handwheel 20 drives the threaded rod 22 to rotate. The threaded rod 22 uses the effect of the thread to drive the screw sleeve 24 to move upward, and the screw sleeve 24 drives the upper box body 12 to move upward through the transmission of the connecting plate 25, the adjusting rod 26 and the adjusting plate 27, so that the overall usable height is increased. At the same time, the corrugated sheet 11 is deformed to extend its usable area to ensure the thermal insulation effect in the overall inner cavity. In the process of the threaded rod 22 driving the screw sleeve 24 and the connecting plate 25 to move upward, the screw sleeve 24 and the connecting plate 25 drive the slider 29 to slide along the inner cavity of the slide seat 28, thereby improving the stability of the screw sleeve 24 and the connecting plate 25 during the up and down movement, and preventing the screw sleeve 24 from rotating due to the rotation of the threaded rod 22.

[0034] In the embodiments of the present invention, please refer to Figure 5 The frame assembly 3 is located in the inner cavity of the lower box body 1, the corrugated sheet 11 and the upper box body 12. The frame assembly 3 includes a lower frame 31, an upper frame 32, a telescopic rod 33 and a stabilizing plate 34. The bottom of the inner cavity of the lower box body 1 is installed with a spliced ​​lower frame 31, and the top of the inner cavity of the upper box body 12 is installed with a spliced ​​upper frame 32. The top of the lower frame 31 is plugged with four telescopic rods 33 for driving the upper frame 32 to move. The top of the telescopic rod 33 is plugged into the bottom of the upper frame 32, and the inner side of the lower frame 31 is installed with a snap-on stabilizing plate 34.

[0035] It should be noted that: in the process of the upper box body 12 moving upward to increase the overall usable area, the upper box body 12 drives the upper frame 32 to move upward, and the upper frame 32 drives the output end of the telescopic rod 33 to extend upward to support the whole, thereby improving the stability of the whole in the subsequent insulation work process and avoiding the occurrence of displacement or tilting of the whole.

[0036] The working principle of the utility model is:

[0037] First, the hand wheel 20 is rotated, and the hand wheel 20 drives the threaded rod 22 to rotate. The threaded rod 22 drives the screw sleeve 24 to move upward through the action of the screw thread. The screw sleeve 24 drives the connecting plate 25 and the adjusting rod 26 to move upward. The adjusting rod 26 drives the upper box body 12 to move upward through the transmission of the adjusting plate 27. Due to the change in the position of the upper box body 12, the corrugated sheet 11 is deformed and extends upward. At the same time, the upper box body 12 drives the upper frame 32 to move upward. The upper frame 32 drives the output end of the telescopic rod 33 to extend upward to support the whole, improve the stability of the whole in the subsequent insulation work process, avoid the occurrence of displacement or tilt of the whole, and increase the overall use area;

[0038] Then, the inspection cover 17 is opened by the zipper, and the 3D printer is placed in the inner cavity of the lower box body 1. At this time, the printer is located on the top of the stabilizing plate 34, and the conveyor belt is facing the end close to the cover plate 16. The stabilizing plate 34 supports the printer so that the printer can run smoothly during use. After the placement is completed, the inspection cover 17 is closed by the zipper to quickly form a stable heat preservation environment;

[0039] In the process of heat preservation of the 3D printer, the pearl cotton layer 102 has good heat preservation and heat insulation performance, effectively blocking the invasion of external cold air and the dissipation of internal heat, and the heat preservation aluminum foil layer 103 has excellent thermal conductivity and heat preservation, which can quickly balance and permanently maintain the temperature distribution in the printing area, and prevent the printing quality problems caused by uneven heat;

[0040] When using a conveyor belt 3D printer to print long-axis objects, the conveyor belt can be extended smoothly through the magnetic strip 14, the discharge port 15 and the cover plate 16, without being restricted by the volume of the device, ensuring that the printed object can extend completely and unhindered along the conveyor belt direction, which not only retains the good thermal insulation effect of the printing area, but also greatly expands the size range of 3D printing.

[0041] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
