[0042] Reference Figures 1 to 9 As shown, an embodiment of the artificial stone heat transfer equipment of the present invention includes: a frame 100, a conveying mechanism 200, and a transfer mechanism.

[0043] Reference Figure 1 , Figure 2 and Figure 3 As shown, the lower end of the frame 100 is used to abut against the support plane of the ground. The frame 100 can serve as the main support for the conveying mechanism 200 and the transfer mechanism, that is, it provides support for the conveying mechanism 200 and the transfer mechanism.

[0044] Reference Figure 1 , Figure 2 and Figure 3 As shown, the frame 100 has a processing station 110, and the conveying mechanism 200 is configured to convey stone along a first direction, so that the stone enters the frame 100 from the feed inlet, passes through the processing station 110, and exits the frame 100 from the discharge outlet 120. The transfer mechanism is located at the processing station 110 and is mainly used to provide heat and pressure to the stone and the transfer piece located at the processing station 110, so that the transfer piece adheres to the surface of the stone to form a decorative pattern.

[0045] Reference Figure 2 , Figure 3 and Figure 4 As shown, specifically, the transfer mechanism is connected to the frame 100. The transfer mechanism includes a lifting drive assembly, an upper heating assembly 300 located above the processing station 110, and a lower heating assembly 600 located below the processing station 110.

The first infrared heating plate 330 is attached to and connected to the end of the first heat-conducting plate 310 facing away from the processing station 110, and is used to provide heat to the first heat-conducting plate 310. The attachment and connection between the first infrared heating plate 330 and the first heat-conducting plate 310 facing away from the processing station 110 helps to increase the heat transfer area between them. The first infrared heating plate 330 transfers heat to the first heat-conducting plate 310 in the form of infrared rays. Compared to resistance heating and oil heating, the first infrared heating plate 330 provides heat to the first heat-conducting plate 310 through infrared heating, resulting in higher heating efficiency and more accurate temperature control. The first heat-conducting plate 310 is used to transfer the heat generated by the first infrared heating plate 330 to the stone and the transfer piece, so as to transfer the pattern on the transfer piece to the stone surface.

[0047] Reference Figure 2 , Figure 3 and Figure 4 As shown, the lower heating assembly 600 includes a second heat-conducting plate 610 and a second infrared heating plate 620. The second infrared heating plate 620 is attached to and connected to the end of the second heat-conducting plate 610 away from the upper heating assembly 300, and is used to provide heat to the second heat-conducting plate 610. The second infrared heating plate 620 is attached to and connected to the second heat-conducting plate 610 facing away from the processing station 110, which helps to increase the heat transfer area between the second infrared heating plate 620 and the second heat-conducting plate 610. The second infrared heating plate 620 transfers heat to the second heat-conducting plate 610 in the form of infrared rays. Compared with resistance heating and oil heating, the second infrared heating plate 620 provides heat to the second heat-conducting plate 610 through infrared heating, which has higher heating efficiency and higher temperature control accuracy. The second heat-conducting plate 610 is used to transfer the heat generated by the second infrared heating plate 620 to the stone and the transfer piece, so as to transfer the pattern on the transfer piece to the surface of the stone.

[0048] Reference Figure 2 , Figure 3 and Figure 4 As shown, the ink for the pattern or design on the transfer piece will melt and transfer onto the high-temperature stone slab as the temperature rises. The high temperature of the stone slab can help accelerate the transfer efficiency of the pattern or design, thereby improving the heat transfer efficiency and forming stone slabs with various patterns or designs required by different users. It has high applicability, and the use of an upper and lower infrared heating structure at the same time makes it easy to adjust the working temperature and the overall heating is uniform, improving the heat transfer effect.

[0049] Reference Figure 2 , Figure 3 and Figure 4 As shown, the lifting drive assembly can drive the upper heating assembly 300 to move closer to or further away from the processing station 110 to heat and pressurize the stone and transfer parts located at the processing station 110, so as to achieve heat transfer of artificial stone. This artificial stone heat transfer equipment can improve the heat transfer effect by using infrared heating.

[0050] Reference Figure 2 , Figure 3 and Figure 4 As shown, specifically, the first heat-conducting plate 310 and the second heat-conducting plate 610 can be made of materials with good thermal conductivity, such as metal materials, to improve the heating efficiency for stone and transfer parts. The first infrared heating plate 330 and the second infrared heating plate 620 are both far-infrared heating plates.

[0051] Reference Figure 2 , Figure 3 and Figure 4 As shown, compared with traditional transfer equipment that uses resistance heaters or oil heaters as heating devices, the artificial stone heat transfer equipment provided in this embodiment of the invention uses a first infrared heating plate 330 and a second infrared heating plate 620 as heaters, which has at least the following beneficial effects:

[0052] (1) Energy saving: Compared with resistance heaters, infrared heating saves more than 40% of energy. The power consumption of a traditional transfer device using resistance heaters is about 180kw, while this artificial stone heat transfer device only needs 100kw to achieve the same heating effect.

[0053] (2) The heating efficiency is higher. Traditional oil heaters take about one and a half hours to heat to the preset temperature, and traditional resistance heaters take about half an hour to heat to the preset temperature. However, the artificial stone heat transfer equipment provided in this utility model embodiment only takes about fifteen minutes to heat to the preset temperature.

[0054] (3) The temperature control accuracy is higher. The temperature control accuracy of traditional oil heaters is about ±10℃, the temperature control accuracy of traditional resistance heaters is about ±5℃, while the temperature control accuracy of the artificial stone heat transfer equipment provided in this utility model embodiment is about ±3℃.

[0055] Preferably, the transfer material is transfer paper, sublimation flag cloth, vinyl paper, or polytetrafluoroethylene film, but is not limited thereto.

[0056] Reference Figure 5 , Figure 6 and Figure 7 As shown, it can be understood that, specifically, the upper heating assembly 300 also includes a first heat insulation layer 350. The first heat insulation layer 350 covers the end of the first infrared heating plate 330 facing away from the first heat conducting plate 310. By setting the first heat insulation layer 350, the heat dissipation performance of the first infrared heating plate 330 to other directions can be reduced, that is, the heat transfer orientation can be improved, so that more heat can be conducted to the transfer part through the first heat conducting plate 310, thereby improving the heating efficiency and heating transfer effect.

[0057] Reference Figure 5 , Figure 6 and Figure 7 As shown, the surface of the first heat-conducting plate 310 facing away from the processing station 110 is provided with a plurality of first grooves 311 arranged in a planar manner. A first infrared heating plate 330, a first shaping plate 340, and a first heat insulation layer 350 are sequentially stacked within each first groove 311. The upper and lower ends of the first shaping plate 340 are connected to the first heat insulation layer 350 and the first infrared heating plate 330, respectively, and the first shaping plate 340 is connected to the first heat-conducting plate 310. The first shaping plate 340 is used to position and connect the first infrared heating plate 330 and the first heat insulation layer 350 to the first heat-conducting plate 310.

[0058] Reference Figure 5 , Figure 6 and Figure 7 As shown, specifically, the first shaping plate 340 has an upward-facing receiving groove, and the side wall of the receiving groove is provided with a connecting hole. During assembly, the user can place the first infrared heating plate 330 into the bottom of the first recess 311 according to the heating performance requirements, and then place the first shaping plate 340 into the first recess 311 and stack it on top of the first infrared heating plate 330. After the threaded connector passes through the connecting hole, it is connected to the side wall of the first recess 311, thus realizing the connection between the first shaping plate 340 and the first heat-conducting plate 310 and fixing the relative positional relationship between the first infrared heating plate 330 and the first heat-conducting plate 310. Then, the first heat insulation layer 350 is embedded in the receiving groove to realize the positioning and connection of the first infrared heating plate 330, the first shaping plate 340, the first heat insulation layer 350 and the first heat-conducting plate 310.

[0059] Reference Figure 5 , Figure 6 and Figure 7 As shown, specifically, the upper surface of the first heat-conducting plate 310 is connected to multiple reinforcing ribs 312, and the multiple reinforcing ribs 312 connected end to end can jointly enclose a first groove 311. The reinforcing ribs 312 can be used to improve the overall strength and stability of the first heat-conducting plate 310.

[0060] Reference Figure 5 , Figure 6 and Figure 7 As shown, it can be understood that in order to further improve the heating efficiency of the upper heating assembly 300, the upper heating assembly 300 also includes a second heat insulation layer 360. After the first infrared heating plate 330, the first shaping plate 340 and the first heat insulation layer 350 are all placed into the first groove 311, the second heat insulation layer 360 can cover the multiple first grooves 311, thereby closing the upper opening of the first groove 311.

[0061] Reference Figure 5 , Figure 6 and Figure 7 As shown, the artificial stone heat transfer equipment can reduce the heat dissipation performance of the first infrared heating plate 330 to other directions by cooperating with the first heat insulation layer 350 and the second heat insulation layer 360, that is, improve the orientation of heat transfer, so that more heat can be conducted to the transfer part through the first heat conducting plate 310, thereby improving the heating efficiency and the heat transfer effect.

[0062] Specifically, the upper heating assembly 300 also includes a third heat insulation layer 390, which is disposed between the first infrared heating plate 330 and the first shaping plate 340. It can play a buffering role, which helps to avoid the problem of the first infrared heating plate 330 being damaged due to rigid collision caused by the first shaping plate 340 during installation. It also helps to enhance the barrier against upward heat transfer, which helps to reduce the risk of heat transfer to the cable and causing the cable to overheat and be easily damaged. [3]

[0063] Reference Figure 5 , Figure 6 and Figure 7 As shown, it should be noted that the number and size of the first slot 311, as well as the size and performance parameters of the first infrared heating plate 330, can be designed according to actual heating requirements and are not limited here.

[0064] Reference Figure 5 , Figure 6 and Figure 7 As shown, it should be noted that the first insulation layer 350 and the second insulation layer 360 can be high-temperature resistant insulation cotton.

[0065] Reference Figure 5 , Figure 6 and Figure 7 As shown, it can be understood that the upper heating assembly 300 includes a buffer layer 381 and an anti-stick and wear-resistant layer 382 covering the lower end of the first heat-conducting plate 310, with the buffer layer 381 disposed between the first heat-conducting plate 310 and the anti-stick and wear-resistant layer 382.

[0066] Reference Figure 5 , Figure 6 and Figure 7 As shown, specifically, the buffer layer 381 can be a high-temperature resistant felt strip connected below the first heat-conducting plate 310, which can play a buffering role. When the lifting drive component drives the upper heating component 300 to approach the processing station 110, it can avoid damage to the stone or transfer parts located at the processing station 110. In addition, the high-temperature resistant felt strip can play a certain heat preservation role, improve thermal efficiency, save energy, and ensure the temperature of the lower working surface of the upper heating component 300 is stable and uniform.

[0067] Reference Figure 5 , Figure 6 and Figure 7 As shown, the anti-stick and wear-resistant layer 382 can be a Teflon sheet, ensuring that the heated transfer parts and stone do not adhere to the upper heating component 300, thereby ensuring the continuity of the production process and the integrity of the product. Furthermore, the Teflon sheet has excellent heat resistance and can operate for extended periods at temperatures ranging from -190°C to 260°C, making it well-suited for various heating scenarios.

[0068] Reference Figure 5 , Figure 6 and Figure 7 As shown, it can be understood that the heating structure and heating principle of the upper heating component 300 and the lower heating component 600 are the same. The heating structure of the upper heating component 300 and the heating structure of the lower heating component 600 are set up in a mirror image to heat the stone to be processed at the same time, so as to improve the heating efficiency of the stone.

[0069] Reference Figure 9 As shown, specifically, the lower end of the second heat-conducting plate 610 is provided with a plurality of second grooves 611. The grooves 611 are provided with a second infrared heating plate 620, a fourth heat insulation layer 630, a second shaping plate 640 and a fifth heat insulation layer 650 arranged sequentially from top to bottom. The lower heating assembly 600 also includes a sixth heat insulation layer covering the lower end of the plurality of second grooves.

[0070] The fourth heat insulation layer 630 of the lower heating assembly 600 corresponds to the third heat insulation layer 390 of the upper heating assembly 300, and is used to buffer the impact caused to the second infrared heating plate 620 during the installation of the second shaping plate 640, and to block the downward transfer of heat. The second shaping plate 640 of the lower heating assembly 600 corresponds to the first shaping plate 340 of the upper heating assembly 300, and is used to fix the relative position of the second infrared heating plate 620 and the second recess 611. The fifth heat insulation layer 650 of the lower heating assembly 600 corresponds to the first heat insulation layer 350 of the upper heating assembly 300, and is used to block the downward transfer of heat from the second infrared heating plate 620, so as to improve the heating efficiency of the second heat-conducting plate 610. The sixth heat insulation layer of the lower heating assembly 600 corresponds to the second heat insulation layer 360 of the upper heating assembly 300, and is used to block the heat flowing downward out of the second recess 611, so that more of the heat generated by the second infrared heating plate 620 is transferred upward.

The two ends of the drive roller 220 are fixed on the conveyor frame by bearing seats. The coupling is connected to one end of the drive roller 220 through the bearing part on the bearing seat. When the drive motor works, it can drive the drive roller 220 to rotate, thereby realizing the conveying work of the conveying mechanism 200.

Each linear actuator 400 has a movable end and a fixed end arranged vertically. The fixed end is connected to the frame 100, and the movable end is connected to the upper heating assembly 300. The multiple linear actuators 400 are arranged at planar intervals and work together to drive the upper heating assembly 300 to move up and down relative to the processing station 110.

[0078] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the fixed end is connected to the frame 100, while the movable end is connected to the upper heating component 300. That is, the linear actuator 400 is fixed to the lower end of the frame 100. Compared with the suspended installation structure of the linear actuator 400, the driving stability of the linear actuator 400 can be improved, thereby improving the lifting stability of the upper heating component 300.

[0079] Reference Figure 1 , Figure 2 and Figure 3 As shown, in order to further improve the lifting stability of the upper heating component 300, the upper heating component 300 includes a plurality of guide sleeves 510 connected to the first heat-conducting plate 310, and the frame 100 has a plurality of guide posts 520 extending vertically. The guide posts 520 are correspondingly inserted into the guide sleeves 510. By mutually limiting the outer peripheral surface of the guide post 520 and the inner peripheral surface of the guide sleeve 510, the rotation of the upper heating component 300 can be restricted, and the lifting of the upper heating component 300 can be guided, thereby improving the lifting stability of the upper heating component 300.

[0080] Reference Figure 1 , Figure 2 and Figure 3 As shown, it should be noted that the linear actuator 400 can be a linear drive device such as a hydraulic cylinder, a pneumatic cylinder, or a lead screw and slider mechanism.

[0081] Reference Figure 4 , Figure 5 and Figure 6 As shown, it can be understood that the upper heating assembly 300 also includes an upper connecting frame 320 and a plurality of connecting members 370. The upper connecting frame 320 is connected to the upper end of the first heat-conducting plate 310. The connecting member 370 includes a pin 371, a spherical bearing 372 and a lead screw 373. The pin 371 is connected to the side of the first heat-conducting plate 310. The spherical bearing 372 is sleeved on the outer periphery of the pin 371. The two ends of the lead screw 373 are respectively connected to the spherical bearing 372 and the upper connecting frame 320.

[0082] Reference Figure 4 , Figure 5 and Figure 6As shown, considering that the first heat-conducting plate 310 may deform after being heated, resulting in poor alignment of the mounting holes, the artificial stone heat transfer equipment uses multiple connecting components 370 to connect the upper connecting frame 320 with the first heat-conducting plate 310. Specifically, the pin 371 can be inserted through the side of the first heat-conducting plate 310, while the spherical bearing 372 is sleeved on the outside of the pin 371, and the two ends of the lead screw 373 are respectively connected to the spherical bearing 372 and the upper connecting frame 320 to automatically compensate for the misalignment of the axis caused by installation errors and thermal deformation.

[0083] Reference Figure 4 , Figure 5 and Figure 6 As shown, the connection method of the spherical bearing 372 is not easily affected by the thermal expansion and contraction of the suspended first heat-conducting plate 310, thus improving the connection firmness of the first heat-conducting plate 310, avoiding affecting the normal operation of the first heat-conducting plate 310, thereby reducing the impact on equipment operation and ensuring safe operation of the equipment.

[0084] Reference Figure 1 , Figure 2 and Figure 3 As shown, the artificial stone heat transfer equipment also includes multiple protective enclosures 700, which surround the frame 100 and are connected to the edges of the frame 100. The protective enclosures 700 are installed around the four edges of the frame 100 to isolate and protect the working area of ​​the transfer mechanism, preventing external personnel and objects from approaching or contacting the working area and affecting the normal operation of the transfer mechanism, causing unnecessary personal injury and cost losses, reducing potential safety hazards, and further improving the safety of the artificial stone heat transfer equipment.

[0085] Reference Figure 1 , Figure 2 and Figure 3 As shown, the protective enclosure 700 is hinged to the frame 100, and the protective enclosure 700 is equipped with a switch handle to facilitate the installation, maintenance and adjustment of the frame 100 by the staff.

[0086] Reference Figure 1 , Figure 2 and Figure 3 As shown, during use, the operator can rotate the protective enclosure 700 by holding the switch handle and engaging the hinge between the protective enclosure 700 and the frame 100, thereby opening the passage connecting the inside and outside of the frame 100, so that the operator can enter the frame 100 for installation, maintenance, or adjustment.

[0087] Reference Figure 1 , Figure 2 and Figure 3As shown, preferably, the lifting drive assembly, the upper heating assembly 300, the lower heating assembly 600, and the conveying mechanism 200 are connected to an external controller so that staff can make corresponding control adjustments according to different production needs.

[0088] Reference Figure 1 , Figure 2 and Figure 3 As shown in the summary, this utility model, through the conveying mechanism 200, can transport the externally fed stone slabs to be processed to the designated processing station 110, and transport the heat-transfer printed stone slabs to the next processing station 110. The entire process of moving the slabs does not require manual handling, which effectively improves the safety of personnel and thus improves the safety of using the artificial stone heat transfer equipment. At the same time, the lifting drive component, the upper heating component 300, and the lower heating component 600 can work together to pressurize and heat the stone slabs to be processed for heat transfer, thereby improving the working efficiency and quality of the heat transfer equipment.

[0089] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
