Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation structures, in particular to a thermal insulation structure for a printer. Background Art

[0002] A 3D printer is one of the common three-dimensional model manufacturing devices. The 3D printers commonly used in life are generally fused deposition modeling printers. When using such printers, the data of the three-dimensional model needs to be transmitted to the controller, and then the 3D printer is controlled by the controller to perform printing operations.

[0003] Common fused deposition modeling printers have requirements for the ambient temperature during use. When the temperature is high, cooling treatment is required. Similarly, when the temperature is low, heating treatment is also required. The 3D printers on the market use cooling fans for heat dissipation during use, but the 3D printers lack heating devices and cannot provide the normal working temperature of the 3D printers. When the 3D printer is used in winter, the winter temperature is mostly below zero degrees Celsius, and even the situation of more than ten degrees Celsius below zero may occur.

[0004] When the room temperature is too low, on the one hand, it will cause the molten material to solidify too quickly when extruded, making the consumables unable to be stacked normally according to the planned route, resulting in difficulties in forming the three-dimensional model. On the other hand, each component inside the 3D printer has an appropriate working temperature. When the room temperature is too low, it will cause the 3D printer to work abnormally, resulting in the failure of the 3D printing process and making it impossible to manufacture the three-dimensional model normally. Therefore, a thermal insulation structure for a printer is proposed to solve the above-mentioned problems. Content of the Utility Model

Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Such as Figure 1 And Figure 3 In the embodiments proposed in this application, there is: a printer heat preservation structure, including a 3D printer 1, an air supply and temperature raising mechanism 2 and a microcomputer 6 are arranged at the upper end of the 3D printer 1, and the microcomputer 6 is connected to the air supply and temperature raising mechanism 2, and the air supply and temperature raising mechanism 2 is controlled by the microcomputer 6 to produce warm air.

[0025] Specifically, the air supply and temperature raising mechanism 2 is composed of a heat preservation box 201, a heat exchange block 202, a heating block 203 and an intake fan 204. Among them, the heat preservation box 201 is fixed at the upper end of the 3D printer 1, the heat exchange block 202 is fixed inside the heat preservation box 201, the heating block 203 is fixed at the upper end of the heat preservation box 201, the refrigerating end of the heating block 203 extends to the outside of the heat preservation box 201, and the heating end of the heating block 203 contacts the heat exchange block 202 to conduct heat to the heat exchange block 202. The intake fan 204 is arranged at the outer end of the heat preservation box 201. At the same time, the microcomputer 6 is electrically connected to the heating block 203.

[0026] Furthermore, the heat exchange block 202 is arranged in an n-shaped structure, and its length is equal to the inner length of the heat preservation box 201, so as to contact as much air in the heat preservation box 201 as possible and accelerate the heat exchange efficiency of the air.

[0027] Start the microcomputer 6 to heat the air inside the heat preservation box 201 through the heating block 203, so that the air inside the heat preservation box 201 becomes warm air. Then, the heat dissipated by the heating block 203 is transferred to the heat exchange block 202, and the heat exchange block 202 exchanges heat with the air, so that the air is heated and transformed into warm air.

[0028] In a further embodiment, such as Figures 1-3 , a temperature sensor 7 is fixed at the rear end of the 3D printer 1, the temperature sensor 7 is signal-connected to the microcomputer 6, an air pressure block 3 is fixed at the top end of the inner wall of the 3D printer 1, the air pressure block 3 is connected to the air supply and temperature raising mechanism 2, and four groups of transmission pipes 4 are fixed at the outer end of the air pressure block 3. Two groups are respectively arranged on the left and right sides of the transmission pipes 4 and are communicated with the inside of the air pressure block 3, so that the transmission pipes 4 can make the discharge of warm air more uniform and reduce the situation of uneven heating during the heating process.

[0029] Furthermore, the heat preservation box 201 is connected to the inside of the air compressor block 3. After the heat is input into the air compressor block 3 through the air supply and heating mechanism 2, the transmission pipe 4 inputs the heat into the 3D printer 1 to increase the temperature inside the 3D printer 1, thereby ensuring the temperature inside the 3D printer 1 and preventing the temperature inside the 3D printer 1 from being too low, which affects the printing effect.

[0030] Furthermore, a fixing block 5 is fixedly sleeved on the outer side of the transmission tube 4, and the fixing block 5 is fixed to the inner wall of the 3D printer 1. The fixing block 5 fixes and supports the transmission tube 4, so that the transmission tube 4 is more stable when conveying air.

[0031] Furthermore, an air outlet pipe is fixed to the outer end of the 3D printer 1, through which excess gas in the 3D printer 1 is discharged, so as to keep the air pressure inside the 3D printer 1 consistent with that outside.

[0032] When the microcomputer 6 controls the heating block 203 to work, the heating block 203 is powered on for heating, and the air inside the insulated box 201 is heated through the heat exchange block 202 to produce warm air. After the air is heated, the air intake fan 204 is started to blow the air into the interior of the air compressor block 3.

[0033] During the process, the thermal insulation box 201 plays the role of storing air and performs simple heat preservation operations on the heater. In addition, there is air storage space in the thermal insulation box 201 and the air compression block 3, so that the outside air is blown in by the air intake fan 204 and naturally diffuses into the interior of the thermal insulation box 201 and the air compression block 3, so that the air flow speed is reduced, thereby avoiding the situation where the air flow rate entering the box is too fast, which has an adverse effect on the printed model.

[0034] Furthermore, air outlet holes are respectively provided on the opposite sides of the two groups of transmission tubes 4. A number of air outlet holes are evenly distributed on the transmission tubes 4. The warm air is transported through the transmission tubes 4 and discharged into a lower position inside the 3D printer 1 through the air outlet holes. Since the density of the warm air is less than that of the cold air, the warm air in the 3D printer 1 will float upward, and the interior of the box can be fully heated during the rising process of the warm air.

[0035] Working principle: When the 3D printer 1 works in a low temperature environment in winter, the temperature inside the 3D printer 1 is monitored by the temperature sensor 7, and the temperature data is transmitted to the microcomputer 6 in real time. When the temperature is lower than the temperature set by the microcomputer 6, the microcomputer 6 controls the heating block 203 to be powered on. At this time, the heating block 203 heats the heat exchange block 202, and the heat exchange block 202 heats the air inside the insulation box 201, so that the insulation box 201 contains warm air.

[0036] After the air is heated for a period of time (this time can be programmed and set by a microcomputer. Controlling the operation of the device through microcomputer programming is a mature existing technology, so it will not be elaborated here), the microcomputer 6 controls the intake fan 204 to be powered on and work, allowing the air outside the incubator 201 to enter, and pushing the warm air into the inside of the air pressure block 3. The warm air is discharged into the 3D printer 1 through the transmission pipe 4, causing the temperature inside the 3D printer 1 to rise, and the temperature is monitored in real time through the temperature sensor 7 to make the temperature relatively constant.
