Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0054] As shown in Figures 1 to 5 and Figure 11, the detachable heating device 2' for a hot press provided in the embodiments of this application includes a heater 2, a heat-insulating shell 2.5, a first coupler e1, and a pressing member 6.1. The heat-insulating shell 2.5 covers the outer surface of the heater 2. The first coupler is at least partially disposed on the heat-insulating shell 2.5 and is electrically connected to the heater 2. The pressing member 6.1 is disposed on one end of the heat-insulating shell 2.5 and is configured to move at least partially relative to the heat-insulating shell 2.5 when an external force is applied, so that the heating device 2' forms a detachable electrical connection with the main body of the hot press during use. Furthermore, the embodiments of this application also provide a hot press using the above-mentioned heating device 2', wherein the heating device 2' is detachably attached to the main body of the hot press, wherein the frame 3 of the hot press constitutes the main body, and then the hot press is used to perform heat transfer printing on the substrate s.

[0055] The heating device 2' provided in the embodiments of this application can be detachably mounted onto the frame 3 of the hot press for use. When replacing the heating device 2' with the appropriate type and style according to different types and styles of substrates s, the old type and style of heating device 2' is disassembled by operating the pressing member 6.1, and then the new type and style of heating device 2' is quickly mounted onto the frame 3 of the hot press. Simultaneously, the first coupler e1 achieves electrical connection, meaning that the heating device 2' forms a detachable electrical connection with the frame 3 of the hot press during use. Thus, using the heating device 2' provided in the embodiments of this application not only simplifies the replacement and assembly of heating devices 2' of different types and styles but also significantly improves the replacement and assembly efficiency.

[0056] In some embodiments of the heating device 2′, the heating device 2′ further includes a locking part 6.30, which is configured to engage with the pressing member 6.1 to form a detachable locking relationship with the body of the hot press.

[0057] Referring to Figures 14 and 15, in some embodiments, a locking mechanism 6 is provided between the heating device 2′ and the frame 3. The locking mechanism 6 is used to lock and unlock the assembly of the heating device 2′ and the frame 3. The locking mechanism 6 may include a movable locking member 6.2 with elastic passive degree of freedom, a locking portion 6.30 constructed in the heating device 2′, and a pressing member 6.1. The movable locking member 6.2 is configured to elastically insert into the locking end 6.212 of the locking portion 6.30 when the heating device 2′ is installed in place. The pressing member 6.1 is configured to drive the locking end 6.212 out of the locking portion 6.30, thereby unlocking and detaching the heating device 2′.

[0058] Referring to the embodiments shown in Figures 14 and 15, the movable locking member 6.2 is constructed on the frame 3, and the locking part 6.30 is constructed in a wedge shape, which is a wedge-shaped groove constructed on the side of the heating device 2'. The pressing member 6.1 includes a slider 6.11 movably mounted on the heating device 2'. The slider 6.11 is constructed with a control part 6.11' and a contact part 6.111. When the heating device 2' is installed in place, the wedge-shaped locking end 6.212 is inserted into the wedge-shaped groove. Pressing the control part 6.11' causes the contact part 6.111 to abut against the wedge-shaped part of the locking end 6.212, causing it to disengage from the locking part 6.30 and unlock. The wedge-shaped structure of the locking end 6.212 and the locking part 6.30, along with the pressing member 6.1 for unlocking, results in a simple structure, high reliability, and convenient and quick operation.

[0059] Of course, in other embodiments, the movable locking member 6.2 may be constructed on the heating device 2', and the locking part 6.30 may be constructed on the frame 3.

[0060] As shown in Figures 6 to 9, the heater 2 includes multiple substrates 2.0, each substrate 2.0 having a pressing surface 204. The multiple substrates 2.0 are rotatably connected in sequence, and two substrates 2.0 located at both ends each have a substrate free side 2.02. The two substrate free sides 2.02 are spaced apart to form a first gap 200′, which is a space for avoiding the handle or handle connection part. The multiple substrates 2.0 enclose a thermopressing channel 200, and at least one of the two substrate free sides 2.02 can be driven to adjust the size of the thermopressing channel 200. Specifically, as shown in Figures 6 to 9, the heater 2 includes three rigid substrates 2.1, 2.2, and 2.3, each with an inner wall adapted to the shape of the substrate s. Each substrate 2.1, 2.2, and 2.3 has a pressing surface extending between its two ends. The adjacent sides of the substrates 2.1, 2.2, and 2.3 are hinged to form the hot-pressing channel 200. The first free side 201 and the second free side 203 of the first substrate 2.1 and 2.3 are spaced apart and not connected, configured to be relatively driven to adjust the size of the hot-pressing channel 200. All three substrates are made of thermally conductive material. Each substrate is equipped with a first heating element 2.11, a second heating element 2.21, and a third heating element 2.31.

[0061] Regarding the number of substrates 2.0, it can be two, four, or more, depending on the specific requirements. Of course, a smaller number of substrates 2.0, such as two, or four or more, is preferable. When there are two substrates 2.0, the central angle of the pressing surface 204 of one or two substrates 2.0 may be greater than or equal to 180 degrees, potentially affecting the removal of the substrate s after transfer. When there are four or more substrates 2.0, the number of hinged sides increases, raising costs. The specific configuration can be adjusted according to needs.

[0062] In some embodiments, the position and area of ​​the substrate s are concentrated on a portion of the substrate 2.0. Some substrates 2.0 may not be heated, i.e., no heating element 2.01 is provided. In this case, the portion of the substrate without heating element 2.01 can be made of a non-thermal conductive material, or it can be made entirely of a thermally conductive material. For the substrates 2.0 that need to be heated, a corresponding heating element 2.01 is provided.

[0063] Therefore, the number of heating elements in the heater 2 of this application can be determined based on the transfer position and area requirements of the substrate s. Heating elements can be configured only on a portion of the substrate, such as one or two of the first substrate 2.1, the second substrate 2.2, and the third substrate 2.3. The substrates without heating elements are used to hold the substrate s for heat pressing. Specifically, heating elements are configured on the first substrate 2.1 and the second substrate 2.2, while the third substrate 2.3 is not equipped with heating elements. The third substrate 2.3 can be made of either a thermally conductive material or a non-thermally conductive material.

[0064] Referring to Figures 4 and 6, when performing a heat transfer operation using the heater 2 of this application, the transfer material is adhered to the surface of the substrate s, and the flexible heat-conducting layer 1 is wrapped around the outside of the substrate s containing the transfer material to obtain a transfer assembly s′. The flexible heat-conducting layer 1 is configured to wrap the substrate s containing the transfer material and to transfer the heat and pressure of the heater 2.

[0065] The transfer assembly s′ is loaded into the hot-pressing channel 200. The inner diameter of the hot-pressing channel 200 is adjusted by driving the first free side 201 and / or the second free side 203. The pressing surfaces of the first substrate 2.1, the second substrate 2.2, and the third substrate 2.3 press the flexible thermally conductive layer 1 tightly against the transfer material and the columnar substrate s. The heat generated by the first substrate 2.1, the second substrate 2.2, and the third substrate 2.3 is transferred to the transfer material through the flexible thermally conductive layer 1. After maintaining the pressed state for a preset time (this time is specifically set according to the material of the transfer material and the power of the heater 2), the hot-pressing channel 200 is opened by driving the first free side 201 and / or the second free side 203, and the heat-transfer assembly s′ is removed. The flexible thermally conductive layer 1 is made of a flexible material with good thermal conductivity, such as high-temperature thermally conductive silicone, or other known flexible materials with good thermal conductivity.

[0066] In some embodiments, the surface of the substrate s has a stepped structure, such as a stepped cup, and the flexible heat-conducting layer 1 is correspondingly constructed with a stepped structure. Furthermore, the joint edges of the flexible heat-conducting layer 1 are provided with spaces to avoid the handle or handle connection portion. As shown in FIG5, the substrate s is a stepped cup body, and the joint edges of the flexible heat-conducting layer 1 are spaced a certain distance apart, so that the gap formed by the flexible heat-conducting layer 1 wrapping around the joint edges of the substrate s can avoid the hand or handle connection portion.

[0067] Referring to Figures 2, 4 to 7, and 9, in some embodiments, the first free side 201 and the second free side 203 are respectively provided with a first connecting portion 201′ and a second connecting portion 203′, wherein the second connecting portion 201′ is used for mounting and fixing, and the second connecting portion 203′ is used for coupling the thermo-pressing drive portion. In some embodiments, the first connecting portion 201′ and the second connecting portion 203′ are integrally formed with the first free side 201 and the second free side 203, such as by casting or die casting, which can improve the structural strength and precision.

[0068] Referring to Figures 10 to 12, 14, 16, 17, and 19, the hot press provided in this application includes: a frame 3 and a heating device 2'. The frame 3 has a heating device mounting area 300. The heating device 2' includes a heater 2, which is mounted in the heating device mounting area 300, wherein a first connecting portion 201' is directly or indirectly fixedly connected to a heater mounting portion 3.1 on a first side of the heating device mounting area 300.

[0069] Furthermore, the hot press also includes one or more swinging components 4 and a drive device 5. One end of the one or more swinging components 4 is connected to the lower side of the heating device mounting area 300 of the frame 3 in a swinging manner around the third swing axis R3, and the other end is directly or indirectly fixed to the second connection part 203′ of the heater 2. The side of the one or more swinging components 4 adjacent to the heating device 2′ can be constructed to be concave in a shape similar to its outer surface shape, so as to make the product structure more compact. The drive device 5 is installed on the second side of the heating device mounting area 300. The drive part of the drive device 5 is directly or indirectly fixed to the swinging component 4. The heater 2 can be pressed and opened by the drive device 5.

[0070] Referring to Figures 12, 14, 16, 17, 19 to 21, in some embodiments, the heating device mounting area 300 extends horizontally laterally, and the driving device 5 includes an electric actuator 5.2, which drives the second connecting part 203′ to move relative to the first connecting part 201′, thereby realizing the pressing and opening of the heater 2.

[0071] Referring to Figures 1, 2, 4, 5, 11, and 19, in some embodiments, the heater 2 has a first guide rail s1 on its two free sides, and a second guide rail s2 is correspondingly arranged on both sides of the heating device mounting area 300. Through the connection of the first guide rail s1 and the second guide rail s2, the heater 2 can be pushed into the heating device mounting area 300. During installation, it can be locked using a locking mechanism 6, and during disassembly, it can be easily removed using a pop-out mechanism 6.4. The first guide rail s1 and the second guide rail s2 enable quick installation and disassembly of the heater 2, facilitating user operation and eliminating the need for additional disassembly tools. The first guide rail s1 is installed on the first free side 201, and the second guide rail s2 is installed on the second free side 203. Of course, in other substrate embodiments, the first guide rail s1 and the second guide rail s2 are installed on their respective free sides. The first guide rail s1 and the second guide rail s2 can be connected to the first free side 201 and the second free side 203 respectively through a first connecting part 201′ and a second connecting part 203′, such as through connecting parts like screws or rivets. The first guide rail s1 has an upper rail s10 bent outwards at its upper part, and the second guide rail s2 has a lower rail s20 bent inwards at its lower part. When assembled with the second guide rail s2, the upper rail s10 is engaged with the lower rail s20. The second guide rail s2 guides and supports the first guide rail s1 during assembly. The heating device mounting area 300 is horizontally configured, with the first guide rail s1 and the second guide rail s2 horizontally mounted on the upper side of the heating device mounting area 300. The first guide rail s1 and the second guide rail s2 can be formed by bending sheet metal.

[0072] In other embodiments, the heating device mounting area 300 may be vertically arranged.

[0073] The heater 2 used in this application employs a rigid first substrate 2.1, a second substrate 2.2, and a third substrate 2.3 hinged together to form a hot-pressing channel 200. Each substrate is equipped with heating elements 2.11, 2.21, and 2.31, respectively. A flexible heat-conducting layer 1 is used to cover the outside of the substrate s containing the transfer material, resulting in a transfer assembly s′ for heat transfer. The rigid substrates 2.1, 2.2, and 2.3 offer good structural stability, long lifespan, and high reliability. The flexible heat-conducting layer 1 transfers the heat and pressure of the heater 2, allowing for different thicknesses and moduli to be set according to different substrates s, facilitating production and replacement, and improving economic efficiency. The flexible heat-conducting layer 1 has excellent thermal conductivity and can fill and adjust the gaps between the pressing surfaces of the substrates and the transfer material and substrate s, ensuring uniform heating and stress on the transfer material and substrate s, resulting in better heat transfer quality. The flexible heat-conducting layer 1 is easily replaceable and offers excellent economic benefits. Since the first substrate 2.1, the second substrate 2.2 and the third substrate 2.3 are made of thermally conductive materials, they have good heat storage characteristics, avoiding large local heating changes that affect temperature control and ensuring the quality of heat transfer printing.

[0074] The first substrate 2.1, the second substrate 2.2, and the third substrate 2.3 can be made of materials with good thermal conductivity, such as aluminum or its alloys, copper or its alloys, or other metallic materials such as stainless steel or its alloys, cast iron, or other known metallic or non-metallic materials with good thermal conductivity. Specifically, the first substrate 2.1, the second substrate 2.2, and the third substrate 2.3 can be manufactured using die casting or other existing known processes.

[0075] Referring to Figure 9, in some embodiments, the hinge structure of two or more substrates includes a hinge shaft structure 2.42 disposed on the side of one of the substrates, and hinge seats 2.41 disposed on the sides of other adjacent substrates. The hinge shaft structure 2.42 may be constructed with a hinge shaft 2.421 and a hinge channel 2.420 located inside the hinge shaft 2.421. Both ends of the hinge shaft 2.421 are connected to the corresponding substrates via connecting portions. The hinge seat 2.41 is constructed with a hinge recess 2.410 and a hinge limiting portion 2.411. The hinge limiting portion 2.411 engages with the hinge shaft 2.421 by inserting into the hinge channel 2.420. The hinge structure can be integrally formed on the corresponding substrate, such as by die casting or casting. Using the above solution, the structure is stable and installation is convenient and quick. Referring to the specific embodiment shown in Figure 9, the hinge structure 2.4 includes a hinge shaft structure 2.42 disposed on both sides of the second base 2.2, and a hinge seat 2.41 disposed on the adjacent sides of the first base 2.1 and the third base 2.3. Of course, in other embodiments, the hinge structure can also be other known structures, such as hinges, pins, and pin hole structures.

[0076] In some embodiments of this application, the first heating element 2.11, the second heating element 2.21, and the third heating element 2.31 are tubular heating elements, that is, heating element 2.01 is a tubular heating element, embedded in the corresponding first substrate 2.1, second substrate 2.2, and third substrate 2.3, specifically integrated into one piece using a die-casting process. This scheme results in better thermal conductivity and structural stability for the first substrate 2.1, second substrate 2.2, and third substrate 2.3.

[0077] In some embodiments, heating elements are arranged in a ring around their respective substrates. Referring to the embodiments shown in Figures 6 to 8, the first heating element 2.11, the second heating element 2.21, and the third heating element 2.31 are arranged in a ring around the first substrate 2.1, the second substrate 2.2, and the third substrate 2.3, respectively. In some embodiments, the heating elements are arranged in a ring and their joints extend and overlap each other, which avoids uneven temperature at the joints. The joints of the first heating element 2.11, the second heating element 2.21, and the third heating element 2.31 are configured at the ends of the corresponding first substrate 2.1, second substrate 2.2, and third substrate 2.3. This configuration ensures that the cold ends of the heating elements are located at the ends of the corresponding substrates, thus ensuring the uniformity of temperature in the main working parts of the substrates.

[0078] In the heating device 2′ of this application, the heating device 2′ also includes a heat insulation material disposed between the heater 2 and the heat insulation shell 2.5. The heat insulation material is used to keep the heater 2 warm, reduce the cooling rate of the heater 2, and improve the product quality of the heat transfer operation.

[0079] As shown in Figure 6, the heater 2 of this application has at least a portion of its substrate equipped with a temperature sensing element t. The temperature sensing element t is mounted in contact with the substrate and is used to provide feedback on the temperature of the corresponding substrate to the control circuit of the heating element. Furthermore, the temperature sensing element t directly contacts the substrate for detection, resulting in high temperature control accuracy and further ensuring the quality of the heat transfer printing. The temperature sensing element t can be an NTC temperature controller.

[0080] In the embodiments shown in Figures 6 and 7, the first substrate 2.1 and the third substrate 2.3 have a symmetrical structure and can be controlled using the same temperature sensing element t. For example, one temperature sensing element t can be installed on the third substrate 2.3 (or the first substrate 2.1), and another temperature sensing element (not shown) can be installed on the second heating element 2.21. This arrangement can reduce the wiring layout; for example, three detection lines (two detection lines and one common line) can be used for the two temperature sensing elements. In this case, the first heating element 2.11, the second heating element 2.21, and the third heating element 2.31 also only require three power supply lines. That is, the first heating element 2.11 and the third heating element 2.31 share one main power supply line (live wire), the second heating element 2.21 uses another main power supply line (live wire), and the first heating element 2.11, the second heating element 2.21, and the third heating element 2.31 share one common power supply line (neutral wire).

[0081] Referring to Figures 10 to 12, 14, 16, 17, and 19, the hot press provided in this application includes: a frame 3, a heating device 2', one or more swinging members 4, and a drive device 5; the frame 3 has a heating device mounting area 300; the heating device 2' includes a heater 2, which is mounted in the heating device mounting area 300, wherein a first connecting portion 201' is directly or indirectly fixed to a heater mounting portion 3.1 on a first side of the heating device mounting area 300; one end of one or more swinging members 4 is oscillatingly connected to the frame 3 about a third swing axis R3 on the lower side of the heating device mounting area 300 of the frame 3, and the other end is directly or indirectly fixed to a second connecting portion 203' of the heater 2; the side of the one or more swinging members 4 adjacent to the heating device 2' can be configured to be concave, similar to the shape of its outer surface, so as to make the product structure more compact; the drive device 5 is installed on the second side of the heating device mounting area 300, and the drive portion of the drive device 5 is directly or indirectly fixed to the swinging member 4, so that the heater 2 can be pressed and opened by the drive device 5.

[0082] Referring to Figures 12, 14, 16, 17, and 19 to 21, in some embodiments, the heating device mounting area 300 extends horizontally laterally, and the driving device 5 includes an electric actuator 5.2. The electric actuator 5.2 drives the second connecting portion 203′ to move relative to the first connecting portion 201′, thereby achieving the pressing and opening of the heater 2. The electric actuator 5.2 can be a motor driving the second connecting portion 203′ through a lead screw mechanism, or it can be a motor driving the second connecting portion 203′ through a gear train 5.2′ and a connecting mechanism.

[0083] In the hot press of this application, the electric drive 5.2, the rod and nut mechanism 5.23, and the gear train 5.2′ are combined to form a power assembly.

[0084] As shown in Figures 20 and 21, the nut component 5.232 is coupled to the electric actuator 5.2 via a gear train 5.2′, which includes a first meshing component 5.21′ fixedly configured relative to the nut component 5.232. In other embodiments, the nut component 5.232 is directly fixedly connected to the output end of the electric actuator 5.2, such as via a coupling, or the nut component 5.232 and the output end of the electric actuator 5.2 may be an integral structure. The gear train 5.2′ also includes a second meshing component 5.22′ coupled to the electric actuator 5.2, and the nut component 5.232 and the first meshing component 5.21′ are coaxially configured. The gear train 5.2′ is mounted on the drive seat 5.1, and the combined transmission of the first gear meshing component 5.21′ and the worm gear second meshing component 5.22′ improves the driving efficiency. The self-locking property of the worm gear drive can maintain the positional stability of the heater 2, and the gear meshing reduces the transmission backlash, thereby reducing vibration and jamming during operation. At the same time, the coaxial configuration of the gear system 5.2′ and the nut component 5.232 optimizes the power transmission path and further ensures pressure uniformity.

[0085] The drive seat 5.1 is equipped with a movable channel 5.1′ for the axial movement of the screw 5.231. The movable channel 5.1′ of the drive seat 5.1 allows the screw 5.231 to move axially, which can make full use of the internal space of the hot press and make the product structure compact. At the same time, the movable channel 5.1′ has a guiding function to ensure the smooth movement of the screw 5.231 and improve the accuracy of the adjustment of the hot press channel 200.

[0086] Referring to Figures 20 and 21, in some improvements, at least one end of the nut member 5.232 extends into a first engaging member 5.21′, and the nut member 5.232 is mounted to the drive seat 5.1 via one or more bearings 5.23′. By extending the first engaging member 5.21′ from the end of the nut member 5.232 and mounting it to the drive seat 5.1 using bearings 5.23′, the nut member 5.232 and the first engaging member 5.21′ are integrally formed. Directly mounting the bearings 5.23′ using the nut member 5.232 makes the drive device 5 of this application compact, with high transmission accuracy, improving the smoothness of the movement of the transmission member 5.3, and ensuring the stability of the hot-pressing channel 200 adjustment. Specifically, the nut member 5.232 extends into both ends of the first engaging member 5.21′. This structural design ensures balanced force support on both sides of the first engaging member 5.21′, resulting in good stability of the screw 5.231's movement.

[0087] Referring to Figures 20 and 21, the electric actuator 5.2 is mounted on the drive base 5.1, and the second meshing member 5.22′ is a worm gear. By mounting the electric actuator 5.2 on the drive base 5.1 and using the worm gear as the second meshing member, the high reduction ratio characteristic of the worm gear transmission is utilized to improve driving accuracy. The self-locking property of the worm gear prevents the heater 2 from shifting due to external forces, reduces vibration during the heat transfer process, further improves the uniformity of pressure transmission, and avoids jamming caused by unstable driving.

[0088] One embodiment of the electric actuator 5.2 is a motor, with the second engaging member 5.22′ disposed on the output shaft of the motor, which can be either assembled or integrally formed with the output shaft of the motor. The electric actuator 5.2 can be mounted on the drive housing 5.1 via a connector such as screws.

[0089] Referring to Figure 20, one or more guide mechanisms 5.3′ are constructed between the transmission member 5.3 and the drive device 5. Each guide mechanism 5.3′ includes a guide rod 5.31′ constructed in one of the transmission member 5.3 and the drive device 5, and a guide channel 5.32′ constructed in the other. The axes of the guide rod 5.31′ and the guide channel 5.32′ are parallel to the axis of the screw 5.231. The parallel arrangement of the guide rod 5.31′ and the guide channel 5.32′ with the screw 5.231 axis ensures a stable motion trajectory for the transmission member 5.3 when pivoting around the second axis R2. This design reduces the offset between the transmission member 5.3 and the heater 2, avoids uneven pressure transmission due to motion trajectory deviation, and improves the heat transfer quality.

[0090] As shown in Figure 20, the guide mechanism 5.3′ consists of one guide rod 5.31′, one end of which is mounted on the transmission component 5.3. The drive seat 5.1 has a guide channel 5.32′. To ensure smooth and stable guidance, the drive seat 5.1 is fitted with a sliding sleeve 5.33′, the inner hole of which serves as the guide channel 5.32′. Specifically, regarding the installation of the sliding sleeve 5.33′, a sliding sleeve mounting seat 5.34′ can be constructed on the drive seat 5.1, and the sliding sleeve 5.33′ is installed inside the sliding sleeve mounting seat 5.34′.

[0091] One end of the guide rod 5.31′ can be fixed to the transmission component 5.3 by screw 5.35′. Of course, in other embodiments, other known connection structures can also be used.

[0092] The guide rod 5.31′ is preferably a metal rod, and the sliding sleeve 5.33′ is a metal sliding sleeve. This ensures the structural rigidity of the guide mechanism 5.3, thereby ensuring the stability and reliability of the guide.

[0093] Referring to Figures 20 and 21, the transmission component 5.3 includes a transmission body 5.31 and a drive connector 5.32 that are movably mounted relative to each other along the axial direction of the screw 5.231. The drive connector 5.32 pivotally acts on the heater 2 about the second swing axis R2. A force detection element 5.4 is mounted on either the drive connector 5.32 or the transmission body 5.31. One of the transmission body 5.31 or the drive connector 5.32 is configured with a force application point 5.33 that cooperates with the force detection element 5.4. One end of the screw 5.231 is connected to the transmission body 5.31. In response to the movement of the screw 5.231, the force application point 5.33 has a state of applying force or not applying force relative to the force detection element 5.4 on the heater 2. Using the above structure, in the non-forced state, a force (detectable by the force detection element 5.4) is generated between the force application point 5.33 and the force detection element 5.4, causing the force detection element 5.4 to detect a zero pressure signal. This achieves automatic reset of the heat transfer pressure data, eliminates interference from the previous heat transfer pressure detection value on the pressure detection of the next heat transfer, ensures that the initial pressure detection value is accurately zeroed, improves the real-time performance and repeatability accuracy of force feedback during hot pressing, and reduces heat transfer quality fluctuations caused by accumulated errors. Specifically, to ensure a zero-pressure state between the force application point 5.33 and the force detection element 5.4 in the non-forced state, a screw 5.231 can be used to drive the force application point 5.33 away from the force detection element 5.4 to achieve the non-forced state.

[0094] The transmission body 5.31 is constructed with a guide rod mounting hole 5.36′, which is a countersunk hole extending along the direction of the guide channel 5.32. One end of the guide rod 5.31′ is mounted in the guide rod mounting hole 5.36′, and a screw 5.35′ is inserted into the guide rod mounting hole 5.36′ from the other end and connected to that end of the guide rod 5.31′ (specifically, that end of the guide rod 5.31′ is constructed with a threaded hole), thereby fixing the guide rod 5.31′ axially to the transmission body 5.31.

[0095] In some embodiments, the hot press further includes a reset feature k1′, which may include a first detection element k1 fixedly configured relative to one of the drive connector 5.32 and the transmission body 5.31, and a trigger part k12 fixedly configured relative to the other of the drive connector 5.32 and the transmission body 5.31. The first detection element k1 is electrically connected to the control circuit of the control electric actuator 5.2. In response to the drive connector 5.32 moving to the maximum position relative to the opening direction of the heater 2, the trigger part k12 triggers the first detection element k1, causing the electric actuator 5.2 to stop driving. This solution ensures that the heater 2 can be controlled to be in the maximum open position after each operation, facilitating the user's loading and unloading of workpieces. On the other hand, different workpieces, due to different operating conditions (such as heat transfer materials, pressure, etc.), have different moving distances of the drive connector 5.32 relative to the transmission body 5.31 during operation. After the operation is completed, it is necessary to ensure that the user can easily remove the workpiece and easily load the workpiece before the next operation. Therefore, this improvement effectively solves the above problems by controlling the heater 2 to be in the maximum open position during each non-operation state through the reset feature k1′.

[0096] Referring to Figure 20, as a specific implementation, the first detection element k1 can be a micro switch, which has a first unlocking part k11. The first detection element k1 is mounted on the drive connector 5.32 and electrically connected to the control circuit of the control electric actuator 5.2. The trigger part k12 is constructed on the transmission body 5.31, which can be a protruding structure. When the drive connector 5.32 moves to its minimum distance from the transmission body 5.31, the trigger part k12 contacts the first unlocking part k11. The micro switch transmits a signal to the control circuit of the control electric actuator 5.2, and the electric actuator 5.2 stops driving. At this time, the heater 2 is in the maximum open position. The first detection element k1 uses a micro switch, which has a simple structure, high reliability, and good economy.

[0097] Referring to Figure 20, the first detection element k1 is mounted on the lower side of the drive connector 5.32, and the trigger part k12 is constructed on the lower side of the transmission body 5.31. Specifically, the trigger part k12 can be integrally injection molded with the transmission body 5.31.

[0098] Of course, the configuration positions of the first detection element k1 and the trigger part k12 can be interchanged, that is, the first detection element k1 is installed on the transmission body 5.31, and the trigger part k12 is configured on the drive connector 5.32.

[0099] In addition to the micro switch mentioned above, the first detection element k1 can also be other known electrical components that can perform related functions, such as photoelectric switches, Hall switches, etc.

[0100] Referring to the embodiments shown in Figures 12, 14, 16, 17, and 19 to 21, the drive device 5 further includes a drive base 5.1 and a transmission component 5.3. The drive base 5.1 has a guide channel 5.10 extending vertically along the heater 2. The drive base 5.1 is oscillatingly connected to the frame 3 around a first swing axis R1. The transmission component 5.3 is movably mounted on the guide channel 5.10, and its first end is oscillatingly connected to the swing component 4 around a second swing axis R2. An electric actuator 5.2 is mounted on the outer end of the drive base 5.1, and the electric actuator 5.2 is coupled to the transmission component 5.3. With this design, the transmission component 5.3 adjusts the direction of the driving force as the heater 2 changes, ensuring a linear effect of pressure input.

[0101] In some embodiments, the swing member 4 is provided in pairs. The drive seat 5.1 is swingably connected to the frame 3 via the first pivot member R1′, and the axis of the first pivot member R1′ is the first swing axis R1. The transmission member 5.3 is swingably connected to the swing member 4 via the second pivot member R2′, and the axis of the second pivot member R2′ is the second swing axis R2. The swing member 4 is swingably connected to the lower side of the heating device mounting area 300 of the frame 3 via the third pivot member R3′, and the axis of the third pivot member R3′ is the third swing axis R3. The first pivot member R1′, the second pivot member R2′, and the third pivot member R3 may include bolts and nuts with threads at both ends.

[0102] Referring to Figures 12, 14, 16, 17, and 19 to 21, in some embodiments, the electric actuator 5.2 includes a rotary drive device and a lead screw and nut mechanism 5.23. The rotary drive device includes a motor 5.21 and a reduction mechanism 5.22 (i.e., gear train 5.2′). The screw of the lead screw and nut mechanism 5.23 is coupled to the output end of the reduction mechanism 5.22. The nut of the lead screw and nut mechanism 5.23 is fixedly mounted on the drive base 5.1. The drive base 5.1 is constructed with a drive avoidance channel 5.30 extending along the guide channel 5.10 to avoid movement of the lead screw. The drive avoidance channel 5.30 can connect both sides to avoid the first pivot member R1′.

[0103] Referring to Figures 20 and 21, in some embodiments, a force detection element 5.4 is provided to detect the force between the transmission component 5.3 and the heating device 2′. The control circuit adjusts the operating state of the control motor 5.21, such as start / stop and speed, based on the feedback signal from the force detection element 5.4. The force detection element 5.4 can detect the magnitude of the force applied by the heater 2 to the transfer assembly s′. According to the requirements of different heat transfer pressures, the driving force of the electric actuator 5.2 can be intelligently adjusted. The driving force of the electric actuator 5.2 can be adjusted in real time during the operation to achieve differentiated control of the heat transfer and ensure the quality of the heat transfer.

[0104] In the embodiments shown in Figures 20 and 21, the transmission component 5.3 includes a transmission body 5.31 and a drive connector 5.32 movably mounted in the guide channel 5.10. The first end of the transmission body 5.31 is displaceable relative to the drive connector 5.32 along the direction of the guide channel 5.10. The drive connector 5.32 is oscillatingly connected to the swing component 4 around the second swing axis R2. The force detection element 5.4 is mounted on the drive connector 5.32. The transmission body 5.31 is configured with a force-bearing point 5.33 that cooperates with the force detection element 5.4. Using the above scheme, the heat transfer pressure can be accurately detected and controlled with a fast response speed. Since the transmission body 5.31 can be displaced relative to the drive connector 5.32 along the direction of the guide channel 5.10, when the inner diameter of the hot pressing channel 200 is increased, the drive connector 5.32 moves away from the force detection element 5.4, opening the heater 2. At the same time, the force detection element 5.4 resets, ensuring the accuracy of detection.

[0105] In the embodiments shown in Figures 20 and 21, the first end of the transmission body 5.31 is constructed with a drive connection groove 5.310 for movably assembling the drive connector 5.32. The drive connector 5.32 is movably assembled in the drive connection groove 5.310 along the guide channel 5.10. The two sidewalls of the drive connection groove 5.310 are constructed with movable holes 5.312 for the second pivot member R2′ to pass through. The size of the movable holes 5.312 is at least larger than that of the second pivot member R2′ along the guide channel 5.10, so that when the transmission body 5.31 retracts relative to the drive connector 5.32, the second pivot member R2′ is prevented from interfering with the movement of the transmission body 5.31. On the other hand, when the transmission body 5.31 retracts relative to the drive connector 5.32 until the sidewall of the movable hole 5.312 abuts against the second pivot member R2′, the swing member 4 swings in the opening direction, thereby opening the heater 2.

[0106] The frame 3, located on the side of the heating device mounting area 300, has a second coupler e2 electrically connected to the hot press circuit. When the heating device 2' is externally assembled into the heating device mounting area 300, the first coupler e1 and the second coupler e2 are detachably coupled, allowing the heater 2 circuit to be electrically connected to the hot press circuit. The configuration of the first coupler e1 and the second coupler e2 facilitates quick replacement of the heating device 2', allowing users to easily replace different heating devices 2'. The heater 2 circuit includes a power supply circuit and a detection circuit. The first coupler e1 and the second coupler e2 of this application are plug-in type structures, typically including a male terminal and a female terminal. Both the male and female terminals include corresponding electrical terminals. The number of electrical terminals can be selected according to actual needs, such as the number of lines, specifically the number of power supply lines and detection lines.

[0107] Referring to Figure 15, in some embodiments, the frame 3 is equipped with a pop-out mechanism 6.4. When the heating device 2' is installed in place, the pop-out mechanism 6.4 is pushed to compress and store energy. Since the heating device 2' is locked by the locking mechanism 6, the pop-out mechanism 6.4 remains in the compressed and stored energy state. When the user unlocks it by pressing the member 6.1, the pop-out mechanism 6.4 releases energy and pushes out the heating device 2', making it convenient for the user to remove.

[0108] The pop-out mechanism 6.4 may include one or more guide members 6.41, a sliding member 6.42 mounted on the guide member 6, and a second elastic member 6.43 acting on the sliding member 6.42 and the one or more guide members 6. The heating device 2' has a push top 6.3' corresponding to the sliding member 6.42 on its side. When the heating device 2' is installed in place, the push top 6.3' pushes the sliding member 6.42 to move and compress the second elastic member 6.43. The pop-out mechanism 6.4 allows the heating device 2' to pop out of the frame 3 a certain distance when the locking mechanism 6 is unlocked, facilitating user removal of the heating device 2' and enabling quick installation and removal.

[0109] In one embodiment, the ejection mechanism 6.4 includes two guide members 6.41, and a slider 6.42 is slidably connected to the two guide members 6.41 through a hole structure. A second elastic member 6.43 is disposed between each guide member 6.41 and the slider 6.42. The second elastic member 6.43 is a spring sleeved on the guide member 6.41. Specifically, the guide members 6.41 can be threadedly assembled onto the frame 3.

[0110] Referring to Figures 1, 2, 4, 5, 11, and 12, the heat-insulating outer shell 2.5 may comprise two or more heat-insulating sub-shells hinged together, with at least one hinge corresponding to the opening side of the hot-pressing channel 200. The heat-insulating sub-shells have two structures that are directly or indirectly fixedly connected to the free side, corresponding to the first free side 201 and the second free side 203, respectively. Using this scheme, the heat-insulating sub-shells serve to insulate and protect the heater 2. Having at least one hinge corresponding to the opening side of the hot-pressing channel 200 allows the heat-insulating outer shell 2.5 to adapt to the changing trend and position of the heater 2 during the hot-pressing process, avoiding interference with the opening and closing of the hot-pressing channel 200.

[0111] Referring to the embodiments shown in Figures 1, 2, 4, 5, and 11, the heat-insulating outer shell 2.5 includes a first heat-insulating sub-shell 2.51 and a second heat-insulating sub-shell 2.52. The first heat-insulating sub-shell 2.51 and the second heat-insulating sub-shell 2.52 are hinged to adjacent sides, and the hinge portion of the first heat-insulating sub-shell 2.51 and the second heat-insulating sub-shell 2.52 corresponds to the opening of the thermopressing channel 200. The free sides of the first heat-insulating sub-shell 2.51 and the second heat-insulating sub-shell 2.52 can be connected to the corresponding first guide rail s1 and / or the first connecting portion 201′ and the second connecting portion 203′ via connectors such as screws.

[0112] An air gap 2-2′ is configured between the outer shell of the insulation substructure and the substrate. The air gap 2-2′ can effectively block the temperature of the substrate, providing a safer insulation effect. Furthermore, insulation material can be installed within the air gap 2-2′ to further improve the insulation performance.

[0113] The hinge between adjacent heat insulation sub-shells can be achieved by providing a movable groove 2.54 on at least one end wall 2.511 of one heat insulation sub-shell and a limiting part 2.53 on the end wall 2.521 of the other heat insulation sub-shell. The limiting part 2.53 can be a protrusion integrally formed on the end wall or a connecting part, such as a screw or pin. Alternatively, the hinge between adjacent heat insulation sub-shells can be achieved by providing a movable hole 2.54 on at least one end wall 2.511 of one heat insulation sub-shell and a limiting part 2.53 on the end wall 2.521 of the other heat insulation sub-shell. The limiting part 2.53 can be a protrusion integrally formed on the end wall or a connecting part, such as a pin. A limiting screw is also included, which connects to the limiting part 2.53 to confine the limiting part 2.53 within the movable hole 2.54.

[0114] One or both of the first heat insulation sub-shell 2.51 and the second heat insulation sub-shell 2.52 are fixed to the corresponding base by means of connectors such as screws 2.56.

[0115] The slider 6.11 of the pressing member 6.1 can be mounted to the heat insulation shell 2.5 via the slider mounting base 6.13. The control part 6.11′ is disposed at the end of the heat insulation shell 2.5 for convenient user operation. A locking seat 6.3 is constructed inside the control part 6.11′, and a locking part 6.30 is constructed on the upper part of the locking seat 6.3. The pressing part 6.111 can slide to the locking part 6.30. When the locking end 6.212 is inserted into the locking part 6.30, the pressing part 6.111 can be pushed outward. When the user presses the slider 6.11 through the control part 6.11′, the pressing part 6.111 moves inward to push the locking end 6.212 away from the locking part 6.30 to unlock.

[0116] The locking seat 6.3 is raised on the outer surface of the heat-insulating housing 2.5. The locking seat 6.3 can be configured with two spaced-apart locking walls, forming a sliding channel 6.10 between the two locking walls to accommodate at least a portion of the slider 6.11. The push top 6.3′ can be constructed from the inner end of the locking seat 6.3.

[0117] Referring to Figures 10 to 12, the hot press also includes a housing 7. The frame 3 and the drive unit 5 are installed inside the housing 7. The heating device mounting area 300 is arranged horizontally. At least one port of the hot pressing channel 200 is constructed on the side of the housing 7 to form a housing clearance port 70. The housing port 70 can be used to load the transfer assembly s′. The flexible heat-conducting layer 1 is wrapped around the outside of the substrate s loaded with the transfer material to obtain the transfer assembly s′. The transfer assembly s′ is loaded into a rigid heater 2 with an adjustable hot pressing channel 200. The drive unit of the heater 2... The hot-pressing channel 200 is reduced to press the flexible heat-conducting layer 1 onto the transfer material and the columnar substrate s for a preset time. The heater 2 includes two or more rigid substrates 2.1, 2.2, and 2.3 with inner walls adapted to the shape of the substrate s. The adjacent sides of the two or more substrates 2.1, 2.2, and 2.3 are hinged to enclose the hot-pressing channel 200, and two free sides 201 and 203 are arranged at intervals to adjust the size of the hot-pressing channel 200. At least a portion of the substrates 2.1, 2.2, and 2.3 are equipped with heating elements 2.11, 2.21, and 2.31. In the embodiments of this application, the two sides of the housing 7 are constructed with housing ports 70 corresponding to the two ports of the hot-pressing channel 200, and the upper side of the housing 7 is constructed with a workpiece clearance groove 7' corresponding to the opening of the hot-pressing channel 200. The workpiece clearance groove 7' can be used to avoid some protruding structures on the surface of the transfer material, such as a cup handle. As shown in Figures 10 to 12, the surface of the housing 7 can be used to construct the control panel e.

[0118] In some embodiments, at least one side of the workpiece clearance groove 7′ is provided with an inwardly extending workpiece clearance groove wall 7.1′ or 7.2′. As shown in FIG13, a cover receiving channel 7.20′ extending along the workpiece clearance groove 7′ can be constructed on the workpiece clearance groove wall 7.2′. The cover 8 is movably fitted into the cover receiving channel 7.20′ and configured to be pulled out or stored relative to the cover receiving channel 7.20′ to cover at least a portion of the workpiece clearance groove 7′ or to open the workpiece clearance groove 7′. The cover 8 can improve the safety features of the product, preventing items, fingers, etc., from entering the workpiece clearance groove 7′.

[0119] In some embodiments, as shown in Figures 12 and 13, the cover 8 may be configured with a ventilation mesh structure 80 to reduce the impact on the heat dissipation performance of the device.

[0120] In some embodiments, inwardly extending workpiece clearance groove walls 7.1' and 7.2 are respectively constructed on both sides of the workpiece clearance groove 7'. The workpiece clearance groove wall 7.2' is constructed with a cover receiving channel 7.20'. A positioning structure can be constructed between the cover 8 and the workpiece clearance groove wall 7.1', such as a spring-loaded buckle 8.1 on the cover 8 and a corresponding latch on the workpiece clearance groove wall 7.1'. The cover 8 can be constructed with a control part for controlling its movement.

[0121] As shown in Figures 17 and 18, the hot press includes a housing 7, a cover 8, and a trigger sensor k3. The frame 3, the heating device 2', and the trigger sensor k3 are all located inside the housing 7. The trigger sensor k3 is mounted on the frame 3. The upper side of the housing 7 has a workpiece clearance groove 7' facing the heating device 2'. The cover 8 is movably mounted on the housing 8. The cover 8 has a pulled-out state that blocks the workpiece clearance groove 7' and a retracted state that allows at least part of the workpiece clearance groove 7' to pass through. The trigger sensor k3 is triggered to provide a feedback protection signal when the cover 8 is in the retracted state. Thus, by cooperating with the trigger sensor k3, the mechanism can detect whether the cover 8 is in the retracted state that avoids the workpiece clearance groove 7'. When the detection cover 8 is detected to be in the storage state of avoiding the workpiece clearance groove 7′, the sensor k3 is triggered to provide a feedback protection signal and the heat transfer work cannot be performed. At this time, the heater 2 and other components will not be powered on to prevent foreign objects from entering the workpiece clearance groove 7′ during the heat transfer process and affecting the heat transfer quality. In particular, it prevents the risk of accidental hand injury or burns caused by the hand entering the workpiece clearance groove 7′.

[0122] Furthermore, as shown in Figures 17 and 18, the cover 8 is provided with an extension arm 8.2, which has a trigger end 8.21. When the cover 8 is in the retracted state, the trigger end 8.21 triggers the trigger sensor k3 and feeds back a protection signal.

[0123] In some embodiments, the flexible thermally conductive layer 1 is an unfoldable structure, with its two ends close together when it is rolled up to the outer surface of the transfer material.

[0124] In some embodiments, the flexible thermally conductive layer 1 is silicone.

[0125] In some embodiments, the substrates 2.1, 2.2, and 2.3 are configured as three pieces, wherein the inner sides of the two side substrates 2.1 and 2.3 are respectively connected to the two side sides of the middle substrate 2.2, and the outer sides of the two side substrates 2.1 and 2.3 are arranged at intervals to form the free sides 201 and 203.

[0126] In some embodiments, heating elements 2.11, 2.21, and 2.31 can be laid on the corresponding substrates 2.1, 2.2, and 2.3 using a die-casting process.

[0127] In some embodiments of this application, the pressing member 6.1 of the heating device 2' is configured as a non-movable member relative to the heat insulation shell 2.5, for example, the pressing member 6.1 is a wedge-shaped protrusion. When the heating device 2' is installed into the heating device mounting area 300, the wedge-shaped protrusion abuts and weds tightly against the inner wall of the heating device mounting area 300, thus temporarily stabilizing the heating device 2' within the heating device mounting area 300. When it is necessary to disassemble the heating device 2', it can be easily and quickly pulled out of the heating device mounting area 300 by force.

[0128] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
