Description

Technical Field

[0001] This application relates to the field of wax film printer technology, specifically a gold wax film printer with constant temperature cooling. Background Technology

[0002] Gold wax film printing technology is mainly based on 3D printing technology. It uses special wax materials to print wax films with fine structures and complex shapes. Then, through a series of process steps, the wax film is transformed into gold products. This technology not only improves production efficiency but also greatly reduces manufacturing costs, making customized gold products more popular.

[0003] Gold wax film printing technology has attracted much attention due to its high precision and high-quality output. However, with the widespread application of this technology, the challenges it faces are becoming increasingly prominent. In particular, ensuring a stable temperature environment during the printing process has become an urgent problem to be solved. Although traditional gold wax film printers can achieve basic printing functions, they often lack advanced temperature control mechanisms, resulting in unstable printing effects. Temperature fluctuations directly affect the fluidity and curing speed of the wax material, leading to unevenness between printed layers and deformation of the overall structure. This not only reduces the aesthetics and practicality of the product but also increases the cost of subsequent repair and processing. To solve the above problems, a gold wax film printer with constant temperature cooling has been proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a gold wax film printer with constant temperature cooling, which ensures the stability of the printing process through precise temperature control, thereby improving printing accuracy and wax film quality.

[0005] To achieve the above objectives, this application provides the following technical solution: a gold wax film printer capable of constant temperature cooling, comprising a wax film printer body and a drive mechanism, wherein a print head is mounted on the drive mechanism, and a constant temperature cooling mechanism is provided on the outside of the print head, the constant temperature cooling mechanism comprising a power module and a cooler housing fixedly connected to the outer surface of the print head, and two first copper plates fixedly connected to the inner wall of the cooler housing, wherein the positive and negative terminals of the power module are electrically connected to the two first copper plates respectively through two wires.

[0006] The outer surfaces of the two first copper plates are respectively equipped with N-type semiconductors and P-type semiconductors. The inner wall of the cooler housing is fixedly connected to a second copper plate. The outer surfaces of the N-type semiconductors and P-type semiconductors are both mounted on the second copper plate. The outer surface of the cooler housing is fixedly connected to a heat sink. A fan is fixedly connected to one side of the print head. A temperature sensor is installed at the bottom of the print head. A printing platform is installed at the bottom of the wax film printer body. A heating plate is embedded in the inner wall of the printing platform. A printing plate is fixedly connected to the upper surface of the heating plate.

[0007] Through the above-mentioned solution, a meticulously designed constant-temperature cooling mechanism can precisely control and maintain the printhead within a set constant temperature range. This innovative measure effectively solves the problem of decreased printing accuracy caused by temperature fluctuations in traditional gold wax film printers, thereby significantly improving the accuracy and reliability of printing results. The synergistic effect of the introduced N-type and P-type semiconductors and temperature sensors not only enables real-time monitoring of the printhead temperature but also dynamically adjusts the working state of the constant-temperature cooling mechanism according to temperature changes, ensuring temperature stability and consistency during the printing process. This, in turn, improves the stability of wax film quality and yield. In addition, the heating plate embedded in the printing platform is another highlight of this technology. By activating the heating plate, the temperature of the printing plate is kept stable during the printing process, significantly enhancing the adhesion between the wax film and the printing plate, effectively reducing the risk of printing failure due to poor adhesion. This improvement not only increases printing efficiency but also reduces material waste and post-processing costs.

[0008] Furthermore, the drive mechanism includes a sleeve fixedly connected to the upper surface of the wax film printer body, a lead screw rotatably sleeved on the inner wall of the sleeve, and a servo motor fixedly connected to the top of the sleeve.

[0009] With the above solution, when the servo motor starts, it can drive the lead screw to rotate inside the sleeve.

[0010] Furthermore, the output shaft end of the servo motor is fixedly connected to the top end of the lead screw, and a sleeve block is threadedly connected to the outer surface of the lead screw. The outer surface of the sleeve block is slidably connected to the inner wall of the sleeve.

[0011] The above method allows the sleeve block to move up and down within the inner wall of the sleeve by rotating the lead screw.

[0012] Furthermore, an electric slide rail is fixedly connected to one side of the sleeve block, and the print head is mounted on the outside of the electric slide rail.

[0013] The above solution allows for adjustment of the printhead's horizontal position when the electric slide rail is activated, facilitating the printing process.

[0014] Furthermore, buzzers and alarm lights are installed on both sides of the bottom of the wax film printer body.

[0015] With the above solution, when the temperature is abnormal, a warning can be issued by the buzzer and alarm light, which will facilitate timely adjustment of the constant temperature refrigeration mechanism.

[0016] Furthermore, a control component is installed at the bottom of the wax film printer body, and the control component contains a controller.

[0017] The above solution allows for convenient control of the wax film printer body during printing by setting up control components.

[0018] Furthermore, a protective cover is installed on the outside of the wax film printer body, and ventilation openings are provided on both sides of the outer surface of the protective cover.

[0019] The above solution ensures effective ventilation of the protective cover through the ventilation openings, making it convenient to use.

[0020] Furthermore, a door is installed on the front of the protective cover, and a handle is fixedly connected to the outer surface of the door.

[0021] The above solution allows the protective cover to be kept in a relatively sealed state during printing, providing protection for the components inside the cover.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This temperature-controlled gold wax film printer, through its meticulously designed temperature-controlled cooling mechanism, precisely controls and maintains the printhead within a set temperature range. This innovative approach effectively solves the problem of decreased printing accuracy caused by temperature fluctuations in traditional gold wax film printers, thereby significantly improving the accuracy and reliability of the printing results. Through the synergistic effect of N-type and P-type semiconductors and temperature sensors, the printhead temperature can be monitored in real time, and the working state of the cooling mechanism can be dynamically adjusted according to temperature changes to ensure temperature stability during the printing process. Furthermore, the printer incorporates a built-in heating plate in the printing platform, which maintains a stable printing plate temperature, enhances the adhesion between the wax film and the printing plate, and effectively reduces the risk of printing failures. In summary, this technological innovation, through precise temperature control, significantly improves printing accuracy, wax film quality stability, and printing efficiency, while reducing material waste and post-processing costs, demonstrating superior practical value.

[0030] The technical solutions of 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3 The gold wax film printer with constant temperature cooling in this embodiment includes a wax film printer body 1 and a drive mechanism 2. A print head 3 is mounted on the drive mechanism 2. The drive mechanism 2 includes a sleeve 201 fixedly connected to the upper surface of the wax film printer body 1, a lead screw 202 rotatably sleeved on the inner wall of the sleeve 201, and a servo motor 203 fixedly connected to the top end of the sleeve 201. The output shaft end of the servo motor 203 is fixedly connected to the top end of the lead screw 202. When the servo motor 203 starts, it can drive the lead screw 202 to rotate within the inner wall of the sleeve 201. A sleeve block 204 is threadedly connected to the outer surface of the rod 202. The outer surface of the sleeve block 204 is slidably connected to the inner wall of the sleeve 201. The rotation of the screw 202 can cause the sleeve block 204 to move up and down in the inner wall of the sleeve 201. An electric slide rail 205 is fixedly connected to one side of the sleeve block 204. The print head 3 is installed outside the electric slide rail 205. When the electric slide rail 205 is started, the horizontal position of the print head 3 can be adjusted to facilitate the printing work. Through the above steps, the position of the print head 3 can be flexibly adjusted to facilitate the printing work of the print head 3.

[0032] Please see Figure 2 , Figure 3 and Figure 4The printhead 3 is equipped with a constant temperature cooling mechanism 4. The constant temperature cooling mechanism 4 includes a power module 401 fixedly connected to the outer surface of the printhead 3 and a cooler housing 402. Two first copper plates 403 are fixedly connected to the inner wall of the cooler housing 402. The positive and negative terminals of the power module 401 are electrically connected to the two first copper plates 403 through two wires, respectively. N-type semiconductors 404 and P-type semiconductors 405 are respectively mounted on the outer surface of the two first copper plates 403. A second copper plate 406 is fixedly connected to the inner wall of the cooler housing 402. The outer surfaces of the N-type semiconductors 404 and P-type semiconductors 405 are both mounted on the second copper plate 406. When the power module 401 is started, current can flow from the N-type semiconductor to the P-type semiconductor. Semiconductor 404 flows to P-type semiconductor 405, or from P-type semiconductor 405 to N-type semiconductor 404. Due to the characteristics of semiconductor materials, a temperature difference is generated at both ends when current passes through, forming a cold end and a hot end. The cold end absorbs heat, lowering the ambient temperature, while the hot end releases heat. The power module 401 provides a stable DC power supply and adjusts the current as needed, thereby controlling the cooling power and temperature of the thermostatic cooling mechanism 4. Through the cooperation of the above components, the thermostatic cooling mechanism 4 can work efficiently and stably, providing a reliable cooling solution for various application scenarios. By adjusting the voltage and current applied to the thermocouple pair, the cooling speed and cooling capacity can be controlled.

[0033] It should be noted that when current flows through a thermocouple pair consisting of an N-type semiconductor 404 and a P-type semiconductor 405, heat transfer occurs between the two ends, creating a temperature difference and forming hot and cold ends. However, semiconductors have inherent resistance, and the current passing through them generates heat, which affects heat transfer. Furthermore, heat between the two plates also flows in the reverse direction through the air and the semiconductor material itself. When the hot and cold ends reach a certain temperature difference, the amounts of these two types of heat transfer become equal, reaching an equilibrium point where the forward and reverse heat transfers cancel each other out. At this point, the temperature of the hot and cold ends will not continue to change. To achieve a lower temperature, the temperature of the cold end can be lowered by reducing the temperature of the hot end.

[0034] Please see Figure 2 , Figure 3 and Figure 4A heat sink 407 is fixedly connected to the outer surface of the cooler housing 402. The heat sink 407 can accelerate the heat dissipation of the hot end, so that the heat generated can be effectively dissipated to the surrounding environment to ensure the stability and durability of the cooling effect. A fan 408 is fixedly connected to one side of the print head 3. When the fan 408 is turned on, it can enhance the heat dissipation effect and remove the heat on the heat sink 407 by forced convection, further reducing the temperature of the cooler housing 402. A temperature sensor 409 is installed at the bottom of the print head 3 to realize real-time monitoring of the temperature of the print head 3. A printing platform 5 is installed at the bottom of the wax film printer body 1. A heating plate 6 is embedded in the inner wall of the printing platform 5. A printing plate 7 is fixedly connected to the upper surface of the heating plate 6. When the heating plate 6 is turned on, it can preheat the printing plate 7, which can maintain a stable temperature during the printing process and significantly enhance the adhesion between the wax film and the printing plate 7, effectively reducing the risk of printing failure due to poor adhesion. This improvement not only improves printing efficiency, but also reduces material waste and post-processing costs.

[0035] Please see Figure 1 and Figure 2 The wax film printer body 1 has buzzers 8 and alarm lights 9 installed on both sides of its bottom. When the temperature is abnormal, the buzzers 8 and alarm lights 9 can provide an early warning, allowing for timely adjustment of the constant temperature cooling mechanism 4. A control component 10 is installed at the bottom of the wax film printer body 1. The control component 10 contains a controller, which is electrically connected to various electrical components in the device. This allows the control component 10 to control the operation of the electrical components in the wax film printer body 1. The control component 10 can receive signals from the temperature sensor 409. The signal is received, and the output current of the power module 401 is adjusted according to the signal of the temperature sensor 409, so as to achieve precise control of the printing temperature. A protective cover 11 is installed on the outside of the wax film printer body 1. Ventilation ports 12 are opened on both sides of the outer surface of the protective cover 11. The ventilation ports 12 can ensure the ventilation effect of the protective cover 11 and facilitate its use. A cover door 13 is installed on the front of the protective cover 11. A handle is fixedly connected to the outer surface of the cover door 13, which can keep the protective cover 11 in a relatively sealed state during printing and provide protection for the components inside the protective cover 11.

[0036] In this embodiment, the temperature-controlled cooling gold wax film printer, through its meticulously designed temperature-controlled cooling mechanism 4, can precisely control and maintain the printhead 3 within a set constant temperature range. This innovative measure effectively solves the problem of decreased printing accuracy caused by temperature fluctuations in traditional gold wax film printers, thereby significantly improving the accuracy and reliability of the printing results. The synergistic effect of the introduced N-type semiconductor 404 and P-type semiconductor 405 with the temperature sensor 409 not only enables real-time monitoring of the printhead 3 temperature but also dynamically adjusts the working state of the temperature-controlled cooling mechanism 4 according to temperature changes, ensuring temperature stability and consistency during the printing process, thereby improving... The stability of the wax film quality and the yield rate are also significant advantages. Furthermore, the heating plate 6 embedded in the printing platform 5 is another highlight of this technology. By activating the heating plate 6, the temperature of the printing plate 7 is kept stable during the printing process, significantly enhancing the adhesion between the wax film and the printing plate 7. This effectively reduces the risk of printing failure due to poor adhesion. This improvement not only increases printing efficiency but also reduces material waste and post-processing costs. In summary, this technical solution, through the innovative design of the constant temperature cooling mechanism 4 and the heating plate 6, achieves precise temperature control during the gold wax film printing process, significantly improving printing accuracy, wax film quality stability, and printing efficiency, demonstrating clear superiority and practical value.

[0037] The working principle of the above embodiment is as follows: When printing with this device, the heating plate 6 can be activated first to preheat the printing plate 7, and then the power module 401 can be turned on to supply current. The current flows from the N-type semiconductor 404 to the P-type semiconductor 405. Due to the characteristics of semiconductor materials, a temperature difference will be generated at both ends when the current passes through, forming a cold end and a hot end. The cold end absorbs heat, which lowers the ambient temperature, while the hot end releases heat. The heat needs to be dissipated through a heat sink. The heat sink 407 can accelerate the heat dissipation effect of the hot end. At the same time, the fan 408 can be activated to improve the heat dissipation of the heat sink 407, thereby optimizing the cooling efficiency. Furthermore, by adjusting the voltage and current intensity applied to the first copper plate 403, the cooling speed and cooling capacity can be controlled. The temperature sensor 409 can measure the temperature of the print head 3, which allows for dynamic adjustment of the working state of the constant temperature cooling mechanism 4 based on the temperature change of the print head 3, ensuring the stability and consistency of the temperature during the printing process, thereby improving the stability of the wax film quality and the yield.
