Technical Field

[0002] This application relates to the field of heat transfer technology, specifically a heat press that is easy to assemble and disassemble. Background Technology

[0003] This section provides background information relevant to this application and is not necessarily prior art.

[0004] The hot press involved in this application transfers artistic elements (such as patterns, text, colors or combinations thereof) onto a workpiece (such as a cup) through a heat transfer process, and controls the quality of the heat transfer based on the control of temperature, applied pressure and duration.

[0005] This application enables heat transfer printing on the outer surface of a columnar substrate, transferring elements such as patterns, text, and colors onto the substrate surface. Existing hot presses typically include a frame and a heater mounted on the frame. The heater has a hot pressing channel and flexible connecting plates on both sides. The frame has two support parts corresponding to the flexible connecting plates on each side. Because the flexible connecting plates are easily deformed, clamps need to be added to the upper side of the flexible connecting plates during assembly to ensure the heater is securely installed. The clamps, flexible connecting plates, and support parts are then locked together with screws. This results in a complex assembly structure between the heater and the frame, making assembly and disassembly cumbersome and inconvenient for daily use and maintenance. Summary of the Invention

[0006] The purpose of this application is to overcome the problem that the connection structure between the heater and the frame in the prior art is complex, which is not conducive to installation and disassembly, and is not conducive to daily use and maintenance. The application provides a hot press that allows the heater to be movably assembled on the frame along the extension direction of the heating channel by setting a first guide part and a second guide part, thereby realizing quick assembly and disassembly of the heater.

[0007] To solve the above-mentioned technical problems, this application adopts the following technical solution: A conveniently assembled and disassembled hot press includes a heater and a frame. The heater has an adjustable-size hot pressing channel and a first gap extending along the hot pressing channel. First guide portions are respectively arranged on both sides of the first gap. The frame is provided with two second guide portions with adjustable spacing extending along the hot pressing channel. The heater can be movably assembled on the frame along the direction of the hot pressing channel through the movable cooperation of the first guide portions and the second guide portions, and the size of the hot pressing channel can be adjusted in response to the change in the distance between the two second guide portions.

[0008] This application, by providing a first guide section and a second guide section, enables the heater to be movably assembled and disassembled relative to the frame along the direction of the hot press channel. This guide structure simplifies the existing connection structure between the heater and the frame and optimizes the user's operation process for loading and unloading substrates such as cups. When loading and unloading substrates, the heater can be pulled out from the frame for direct operation. Compared with the existing method of fixing the heater to the frame, the hot press of this application is beneficial to the daily use and maintenance of the heater.

[0009] As one specific arrangement of the first guide section and the second guide section, the first guide section is configured as a first guide rail extending along the hot-pressing channel, and the second guide section is configured as a second guide rail corresponding to the first guide rail. The axial extension design of the first guide rail and the second guide rail ensures that the heater moves smoothly along a predetermined path during assembly, avoiding installation errors or component jamming caused by offset or tilting, while enhancing the guiding stability of the structure.

[0010] Furthermore, the first guide rail has an upper rail bent outwards at its upper part, and the second guide rail has a lower rail bent inwards at its lower part. The upper rail is mounted on the lower rail. This type of guide rail structure can reliably support the heater.

[0011] Furthermore, the first guide rail includes a vertically extending guide rail connecting portion, an extension portion extending laterally connected to the guide rail connecting portion, and a vertically extending joining portion connected to the extension portion, wherein the extension portion forms an elongated region between the joining portion and the guide rail connecting portion.

[0012] Furthermore, the first guide rail is constructed with an L-shaped reinforcing wall connecting the bottom of the extension portion and the side of the guide rail connection portion, the L-shaped reinforcing wall extending along the length direction of the first guide rail.

[0013] As another specific arrangement of the first guide section and the second guide section, the second guide section is constructed with a guide channel, and the first guide section is movably installed in the guide channel. The fit between the guide channel and the first guide section is tight, which allows the heater to move smoothly.

[0014] Furthermore, a rolling or sliding contact point is provided between the guide channel and the first guide portion.

[0015] Furthermore, the first guide portion and / or the second guide portion can be constructed as a continuous or discontinuous structure. As an alternative to a continuous structure, a discontinuous structure can also provide guidance and load-bearing capabilities for the first guide portion.

[0016] Furthermore, the base includes a frame and a swinging member. One end of the swinging member is oscillatingly connected to the frame about a third axis parallel to the extension direction of the hot pressing channel. One of the two second guide portions is disposed at the other end of the swinging member, and the other is disposed on the frame. The distance between the two second guide portions is adjusted in response to the swinging of the swinging member relative to the frame. The swinging member allows the size of the hot pressing channel to be adjusted along an arc trajectory, thereby adapting to the shape of cylindrical workpieces such as cups.

[0017] Furthermore, it also includes a drive device, which comprises a driver, a lead screw and nut mechanism, and a transmission component. The drive device is pivotally connected to the frame about a first axis parallel to a third axis. The transmission component is pivotally connected to the swinging component about a second axis parallel to the first axis. The lead screw and nut mechanism includes a screw fixed to the transmission component and perpendicular to the second axis, and a nut component threadedly connected to the screw. The nut component is drive-coupled to the driver. The swinging component swings in response to the movement of the screw. The drive device enables automated adjustment of the hot pressing channel.

[0018] Furthermore, it also includes a locking mechanism for locking and unlocking the heater and the base. The locking mechanism can limit the relative position of the heater and the base, preventing the heater from shifting after it is installed in place.

[0019] Furthermore, it also includes a pop-out mechanism. When the heater is installed in place, the pop-out mechanism is pushed to compress and store energy. In response to the user unlocking the device by unlocking the device, the pop-out mechanism releases energy and pushes the heater out along the second guide section. Based on the first guide section and the second guide section, the pop-out mechanism can automatically pop out the heater along the second guide section when unlocking, improving the convenience of heater disassembly.

[0020] Furthermore, the ejection mechanism includes one or more guide members, a slider mounted on the guide members, and a second elastic member acting between the slider and the one or more guide members. The heater side is equipped with a pusher corresponding to the slider. During heater installation, the pusher pushes the slider to move and compress the second elastic member. Through the cooperation of the guide members, the slider, and the second elastic member, the reliability and consistency of the ejection action can be ensured, improving the smoothness and efficiency of the assembly and disassembly process.

[0021] Furthermore, the locking mechanism includes a movable locking member with a flexible passive degree of freedom, a first locking portion constructed in one of the bases of the heater, and an unlocking member constructed in the other of the bases of the heater. When the heater is installed in place, the movable locking member is inserted into the first locking portion, and the unlocking member is configured to drive the movable locking member out. With the above configuration, when the heater is installed in place, the second locking portion of the first locking is elastically inserted, and the unlocking member is configured to drive the second locking portion out of the first locking portion, making the heating and pressing device unlockable and detachable.

Detailed Implementation

[0023] The specific embodiments of this application are described below with reference to the accompanying drawings.

[0024] See Figures 1 to 5 This embodiment provides a conveniently assembled and disassembled hot press, including a base 30 and a heating and pressing device 2'. The heating and pressing device 2' includes a heater 2, which has an adjustable hot pressing channel 200 and a first gap 200' extending along the hot pressing channel 200. When the size of the hot pressing channel 200 changes, the size of the first gap 200' changes accordingly. The extension direction of the hot pressing channel 200 referred to in this application is the axial direction of the heater 2. First guide portions s1' are respectively arranged on both sides of the first gap 200'. The base 30 is provided with two second guide portions s2' with adjustable spacing extending along the hot pressing channel 200. The heater 2 can be movably assembled on the base 30 along the extension direction of the hot pressing channel 200 through the movable cooperation of the first guide portions s1' and the second guide portions s2', and the size of the hot pressing channel 200 is adjusted in response to the change in the spacing between the two second guide portions s2'.

[0025] Regarding the arrangement of heater 2, in some embodiments, it can be formed by hinged connection of at least two heating units, with the inner sides of the at least two heating units enclosing a thermo-pressure channel 200. The size of the thermo-pressure channel 200 can be adjusted by driving the heating units to swing. The heating unit can include a rigid substrate and a heating element formed on the substrate by die casting, such as a heating tube. The substrate material can be aluminum or its alloy, copper or its alloy, or other materials with good thermal conductivity, such as stainless steel or its alloy, cast iron, or other known materials with good thermal conductivity, such as metals or non-metals.

[0026] In other embodiments of the heater, the heater is composed of a flexible, bendable, and deformable heating element, the inner side of which encloses a thermo-pressure channel 200. The size of the thermo-pressure channel 200 can be adjusted by changing the bending amplitude of the heating element. For example, the heating element includes an outer metal thin wall, an inner flexible heating element such as a heating film, and a flexible substrate located between the metal thin wall and the flexible heating element.

[0027] See Figures 1 to 5In some embodiments, the first guide portion s1' is configured as a first guide rail s1 extending along the hot pressing channel 200, and the second guide portion s2' is configured as a second guide rail s2 corresponding to the first guide rail s1. The first guide rail s1 has an upper rail s10 bent outward at its upper part, and the second guide rail s2 has a lower rail s20 bent inward at its lower part. The upper rail s10 is engaged with the lower rail s20. This type of guide rail structure can reliably support the heater 2.

[0028] In some embodiments, the first guide rail s1 and the second guide rail s2 can be formed by sheet metal bending.

[0029] See Figure 5 In some embodiments, the opening and closing range (i.e., the first gap 200') of the heater 2 varies when heat-pressing substrates of different specifications. For example, when heat-pressing a cup with a handle, the heat-pressing channel 200 is adjusted to be larger to avoid the handle, meaning the first gap 200' is larger than when heat-pressing a cup without a handle. This results in a smaller stroke for the drive device 5 to drive the heater 2. When heat-pressing a cup without a handle, the first gap 200' becomes smaller than when heat-pressing a cup with a handle, thus increasing the stroke for the drive device 5 to drive the heater 2. To avoid adjusting the stroke of the drive device 5 when changing to a different specification of substrate s, the lateral distance of the first guide rail s1 is increased to compensate for the increased stroke. When changing the heat transfer substrate s, only a heater 2 with a correspondingly widened first guide rail s1 is needed, eliminating the need to adjust the stroke of the drive device 5. This allows the drive device 5 to provide sufficient heat-pressing force based on its original stroke. The specific implementation is as follows: Figure 5 As shown, the first guide rail s1 includes a vertically extending guide rail connecting portion s1.1, a laterally extending extension portion s1.2 connected to the guide rail connecting portion s1.1, and a vertically extending joining portion s1.3 connected to the extension portion s1.2. The extension portion s1.2 creates an extended area between the joining portion s1.3 and the guide rail connecting portion s1.1 to compensate for the stroke of the drive device 5, thereby providing sufficient thermo-pressing force to accommodate heat transfer of substrates requiring different opening and closing amplitudes, such as... Figure 5 The width of the extension s1.2 shown is approximately twice the width of the second guide rail s2, thereby moving the assembled second guide rail s2 away from the guide rail connection s1.1.

[0030] See Figure 2 and Figure 5To improve the strength of the extension s1.2, the first guide rail s1 is constructed with an L-shaped reinforcing wall s1.4 connecting the bottom of the extension s1.2 and the side of the guide rail connection s1.1. The L-shaped reinforcing wall s1.4 extends along the length direction of the first guide rail s1 and is preferably an integral structure with the first guide rail s1. Providing the L-shaped reinforcing wall s1.4 can improve the strength of the first guide rail s1.

[0031] See Figure 6 In other embodiments, the second guide portion s2' is configured with a guide channel s2.1', and the first guide portion s1' is movably installed within the guide channel s2.1', meaning the first guide portion s1' can move along the guide channel s2.1'. In some specific embodiments, a rolling or sliding contact point is arranged between the guide channel s2.1' and the first guide portion s1', for example, Figure 6 In the illustrated embodiment, the first guide portion s1' is configured as a slider mounted in the guide channel s2.1', which can slide along the guide channel s2.1' to achieve guidance. Setting it to sliding contact simplifies the guiding structure. In other embodiments, the first guide portion s1' is configured with a roller that rolls into contact with the guide channel s2.1'. Setting it to rolling contact makes the movement of the heater 2 smoother.

[0032] In some embodiments, the first guide portion s1' and / or the second guide portion s2' are constructed as continuous or discontinuous structures. The discontinuous structure refers to the first guide portion s1' and / or the second guide portion s2' being constructed as multiple individual structures arranged at a predetermined interval along the direction extending from the heating channel 200. Compared to a continuous structure, the discontinuous structure serves as an alternative, also providing guidance and support for the first guide portion. Of course, the discontinuous structure of the second guide portion s2' may affect the smoothness of relative movement between the first guide portion s1' and the second guide portion s2' to some extent. However, by setting the interval between the multiple individual structures of the second guide portion s2' to a sufficiently small value, the impact on smoothness can be effectively reduced.

[0033] See Figures 1 to 5 In some embodiments, the base 30 includes a frame 3 and a swing member 4. One end of the swing member 4 is oscillatingly connected to the frame 3 about a third axis R3 parallel to the extension direction of the hot pressing channel 200. One of the two second guides s2' is disposed at the other end of the swing member 4, and the other is disposed on the frame 3. The adjustment of the distance between the two second guides s2' is in response to the swing of the swing member 4 relative to the frame 3.

[0034] See Figures 1 to 5In some embodiments, a drive device 5 is also included. The drive device 5 includes a driver 5.2, a screw and nut mechanism 5.23, and a transmission member 5.3. The drive device 5 is pivotally connected to the frame 3 about a first axis R1 parallel to the third axis R3. The transmission member 5.3 is pivotally connected to the swing member 4 about a second axis R2 parallel to the first axis R1. The screw and nut mechanism 5.23 includes a screw 5.231 fixed to the transmission member 5.3 and extending perpendicularly along the second axis R2, and a nut member 5.232 threadedly connected to the screw 5.231. The nut member 5.232 is drive-coupled to the driver 5.2. When the driver 5.2 drives the nut member 5.232... When rotated, the screw 5.231 moves, applying a force to the transmission component 5.3 (pushing and pulling forces are applied according to the forward and reverse rotation of the nut component 5.232), causing the transmission component 5.3 to rotate around the second axis R2 and push or pull the swing component 4. This, in turn, drives the corresponding first end guide s1' to adjust the heater 2 via the second guide s2', thereby reducing or expanding the hot pressing channel 200. Therefore, the heater 2 changes the size of the hot pressing channel 200 in response to the movement of the screw 5.231. The above method achieves dynamic adjustment of the hot pressing channel 200 through the pivotal connection of the drive device 5 and the linkage of the screw and nut mechanism 5.23, improving pressure uniformity and reducing jamming. The hot pressing channel 200 can be automatically adjusted by setting the drive device 5. Of course, in some other embodiments, the swing component 4 can be manually driven to swing without setting the drive device 5, thus manually adjusting the size of the hot pressing channel 200.

[0035] See Figure 1 , Figure 3 As an improved embodiment, a locking mechanism 6 is also included, which is used to lock and unlock the heater 2 and the base 30. The locking mechanism 6 restricts the relative position of the heater 2 and the base 30, preventing the heater 2 from shifting after it is installed in place.

[0036] See Figure 3 In some embodiments, the heating and pressing device 2' is equipped with a first coupler e1 electrically connected to the circuit of the heater 2, and the frame 3 is constructed with a second coupler e2 electrically connected to the power supply circuit. When the heating and pressing device 2' is assembled from the outside to the frame 3, the first coupler e1 and the second coupler e2 are detachably coupled, so that the circuit of the heater 2 is electrically connected to the power supply circuit. The electrical connection design of the first coupler e1 and the second coupler e2 enables the circuit of the heater 2 and the power supply circuit to be automatically energized during the assembly process, without the need for additional wiring or manual connection operations, improving assembly efficiency and reducing the risk of electrical connection failure; the detachable design of the first coupler e1 and the second coupler e2 takes into account both reliability and convenience.

[0037] See Figures 7 to 11 The locking mechanism 6 includes a movable locking member 6.2 with a flexible passive degree of freedom, a first locking portion 6.30 constructed in the heating and pressing device 2' or the frame 3, and an unlocking member 6.1. The movable locking member 6.2 is configured to elastically insert into a second locking portion 6.212 of the first locking portion 6.30 when the heating and pressing device 2' is installed in place. The unlocking member 6.1 is configured to drive the second locking portion 6.212 out of the first locking portion 6.30, thereby unlocking and detaching the heating and pressing device 2'.

[0038] See Figures 7 to 11 In the illustrated embodiment, the movable locking member 6.2 is constructed on the frame 3, the first locking part 6.30 is a locking groove constructed on the heating and pressing device 2', and the second locking part 6.212 is constructed as a wedge-shaped end adapted to the locking groove. The unlocking member 6.1 includes a slider member 6.11 movably mounted on the heating and pressing device 2'. The slider member 6.11 is constructed with a control part 6.11' and an unlocking part 6.111. When the heating and pressing device 2' is installed in place, the second locking part 6.212 is inserted into the first locking part 6.30. The control part 6.11' drives the slider member 6.11 to move relative to the movable locking member 6.2, causing the unlocking part 6.111 to abut against the wedge-shaped end of the second locking part 6.212, thereby disengaging it from the first locking part 6.30 and unlocking it. Driven by the control unit 6.11', the unlocking unit 6.111 directly acts on the movable locking member 6.2 to achieve rapid unlocking. The control unit 6.11' is designed for intuitive user operation and simplifies maintenance procedures. The second locking part 6.212 and the first locking part 6.30 adopt a wedge-shaped structure to achieve a simple locking structure with high reliability and convenient and quick operation.

[0039] Of course, in other embodiments, the movable locking member 6.2 may be constructed on the heating and pressing device 2', and the corresponding first locking part 6.30 may be constructed on the frame 3.

[0040] In some embodiments, the movable locking member 6.2 includes a movable locking body 6.21 having the second locking portion 6.212, a locking seat 6.23 movably mounted to the frame 3, and a first elastic member 6.22 acting on the movable locking body 6.21 and the locking seat 6.23 to cause the second locking portion 6.212 to extend out of the locking seat 6.23 and having an elastic passive degree of freedom.

[0041] In some embodiments, the movement direction of the movable locking body 6.21 is configured to be perpendicular to the movement direction of the slider member 6.11, so that the force of the first elastic member 6.22 can be applied perpendicularly to the first locking part 6.30 to ensure the stability and reliability of the locking.

[0042] See Figures 11 to 13In some embodiments, the movable lock body 6.21 is constructed with an elastic element mounting groove 6.210 extending along its movable direction. A second locking portion 6.212 is constructed at one end of the elastic element mounting groove 6.210, and a movable end wall 6.213 is constructed at the other end of the elastic element mounting groove 6.210. The lock seat 6.23 is constructed with a movable lock groove 6.230 on which the movable lock body 6.21 is movably mounted. One end of the movable lock groove 6.230 is open, and the other end is constructed with a blocking portion 6.231. The movable lock body 6.21 is movably mounted in the movable lock groove 6.230, and the blocking portion 6.231 is mounted on the inner side of the movable end wall 6.213. The first elastic... Component 6.22 is installed in the elastic component assembly groove 6.210. One end of Component 6.22 acts on the end of the elastic component assembly groove 6.210 adjacent to the second locking part 6.212, and the other end acts on the blocking part 6.231, giving the second locking part 6.212 an elastic passive degree of freedom. When the second locking part 6.212 is subjected to the axial unlocking pressure of the unlocking component 6.1, it compresses the first elastic component 6.22, thereby moving away from the first locking part 6.30 and unlocking is achieved. When the first locking part 6.30 is aligned with the second locking part 6.212, the second locking part 6.212 engages with the first locking part 6.30 under the action of the first elastic component 6.22, thereby locking the heating and pressing device 2'. The movable locking component 6.2 with the above structure is simple, stable, and highly reliable.

[0043] In some embodiments, lock seat 6.23 has lock seat mounting portions 6232 on both sides, and the lock seat mounting portions 6232 are provided with one or more connecting holes 6.2320. The lock seat mounting portions 6232 are connected to the frame 3 through the one or more connecting holes 6.2320 (e.g., by screws).

[0044] See Figures 7 to 11 The slider member 6.11 is provided with an unlocking part 6.111. In response to the unlocking movement of the slider member 6.11, the unlocking part 6.111 drives the second locking part 6.212 to disengage from the first locking part 6.30 to achieve unlocking.

[0045] In some embodiments, the unlocking part 6.111 includes a non-constant profile surface. When the slider member 6.11 moves to unlock, the contact between the non-constant profile surface and the second locking part 6.212 converts the movement of the slider member 6.11 into a pushing force on the movable locking body 6.21, causing it to overcome the retraction of the first elastic member 6.22 and disengage from the first locking part 6.30 to release the locking state. The non-constant profile is defined as not being parallel to the direction of movement of the slider member 6.11.

[0046] like Figures 7 to 11 In the illustrated embodiment, the non-constant profile is specifically an inclined plane.

[0047] In other embodiments, the non-constant profile is an arc surface or a multi-level stepped surface.

[0048] In some embodiments, to facilitate engagement between the slider member 6.11 and the second locking portion 6.212, the slider member 6.11 is provided with a clearance recess 6.30' corresponding to the first locking portion 6.30, and at least one sidewall of the clearance recess 6.30' is provided with the unlocking portion 6.111. The clearance recess 6.30' is configured such that when the second locking portion 6.212 engages with the first locking portion 6.30, the unlocking portion 6.111 is located adjacent to the second locking portion 6.212, thereby improving the unlocking response speed and user experience.

[0049] like Figures 7 to 11 In the illustrated embodiment, the clearance recess 6.30' is arranged adjacent to the locking groove 6.30, and the second locking part 6.212 is simultaneously inserted into the clearance recess 6.30' and the locking groove 6.30.

[0050] like Figures 7 to 11 In the illustrated embodiment, the outer side of the heating and pressing device 2' is provided with an axially extending slide channel 6.10. The slider member 6.11 is at least partially and axially movable within the slide channel 6.10, and is confined within the slide channel 6.10 by a slide cover 6.12. This configuration of the slide channel 6.10 and slide cover 6.12 effectively ensures the smooth movement of the slider member 6.11, and is simple, stable, and reliable. Specifically, the slide cover 6.12 can be assembled to the outer side of the heating and pressing device 2' using a connector such as a screw 6.12'.

[0051] The heating and pressing device 2' has a groove wall 6.10' forming the groove channel 6.10. A first locking part 6.30 is constructed on the wall 6.10' of the groove channel 6.10. An unlocking part 6.111 is assembled on the groove channel 6.10 and corresponds to the axial side of the first locking part 6.30. In response to the heating and pressing device 2' being loaded into place, the force of the first elastic member 6.22 couples the second locking part 6.212 with the first locking part 6.30. Since the unlocking part 6.111 is located on the axial side of the first locking part 6.30, when the user drives the unlocking part 6.111 through the control part 6.11', it can quickly act on the second locking part 6.212 to achieve the unlocking operation, thus improving work efficiency.

[0052] See Figures 10 to 15 The slide channel 6.10 connects to the end of the heating and pressing device 2', and the control part 6.11' of the slider member 6.11 is at least partially located after the end of the slide channel 6.10, configured so that the user can operate it from the outside of the end of the heating and pressing device 2'.

[0053] See Figures 10 to 15In some embodiments, a slider limiting mechanism is constructed between the slide channel 6.10 and the slider member 6.11 to limit their relative positions.

[0054] See Figure 14 and Figure 15 In some embodiments, the slider limiting mechanism includes a first limiting part 6.11a and a second limiting part 6.11 constructed on the slider member 6.11 and arranged between the clearance recess 6.30' and the control part 6.11'. The slide channel 6.10 is constructed with a third limiting part 6.1011 and a fourth limiting part 6.1012 corresponding to the first limiting part 6.11a and the second limiting part 6.11. The third limiting part 6.1011 and the fourth limiting part 6.1012 are respectively used to limit the maximum position of the slider member 6.11 sliding out and the maximum position of the slider relative to the slide channel 6.10. When the slider member 6.11 slides to the maximum position towards the end of the heating and pressing device 2', the third limiting part 6.1011 restricts the first limiting part 6.11a from continuing to slide. When the slider member 6.11 slides to the maximum position towards the interior of the heating and pressing device 2', the fourth limiting part 6.1012 restricts the second limiting part 6.11b from continuing to slide.

[0055] In some embodiments, a slider return spring 6.14 is provided that acts on the slider member 6.11 to reset the clearance recess 6.30' along the direction of the locking groove 6.30. The slider return spring 6.14 can align the clearance recess 6.30' with the locking groove 6.30, thereby ensuring that the second locking part 6.212 can engage with the first locking part 6.30 after the slider member 6.11 moves due to factors such as operation or transportation.

[0056] In some embodiments, the slide channel 6.10 is provided with a first protrusion 6.141, the slider member 6.11 is correspondingly provided with a second protrusion 6.142, and the slider return spring 6.14 is assembled between the first protrusion 6.141 and the second protrusion 6.142.

[0057] See Figures 7 to 11 In some embodiments, the width of the second locking portion 6.212 extends to the locking groove 6.30 and the avoidance recess 6.30', which can ensure reliable locking of the second locking portion 6.212 and the first locking portion 6.30, and also ensure that the unlocking portion 6.111 can drive the second locking portion 6.212 to unlock when unlocking.

[0058] In some embodiments, the first locking portion 6.30 is a locking groove 6.30, the slider member 6.11 is configured with the avoidance recess 6.30' corresponding to the locking groove 6.30, the unlocking portion 6.111 is formed on the sidewall of the avoidance recess 6.30', and the width of the second locking portion 6.212 extends to the locking groove 6.30 and the avoidance recess 6.30'.

[0059] like Figures 7 to 11 In other embodiments, the slide wall 6.10 is constructed with two locking grooves 6.30 opposite to each other, and an avoidance recess 6.30' is disposed between the two locking grooves 6.30. The width of the second locking part 6.212 extends across the avoidance recess 6.30' to the two locking grooves 6.30. With this scheme, the second locking part 6.212 simultaneously engages with both the locking grooves 6.30 and the avoidance recess 6.30', ensuring that the unlocking part 6.111 can quickly act on the second locking part 6.212 to achieve the unlocking operation. The avoidance recess 6.30', disposed between the two locking grooves 6.30, ensures that both sides of the second locking part 6.212 engage with the two locking grooves 6.30 respectively, resulting in balanced force on both sides of the second locking part 6.212, thereby guaranteeing the reliability and stability of the locking effect.

[0060] like Figures 7 to 11 In other embodiments, the axial inner sides of the locking groove 6.30 and the second locking portion 6.212 respectively include a first locking surface 6.31 and a second locking surface 6.2121 that are perpendicular (or substantially perpendicular) to the sliding direction of the slider member 6.11. With the above structure, the heating and pressing device 2' can be effectively locked axially, and the first locking surface 6.31 and the second locking surface 6.2121 can be quickly disengaged during unlocking without interference.

[0061] like Figure 7 , Figure 11 and Figure 12 In the illustrated embodiment, the locking groove 6.30 is a wedge-shaped groove, meaning that the other side of the locking groove 6.30 relative to the first locking surface 6.31 is a transition slope 6.32. The second locking part 6.212 is correspondingly wedge-shaped to fit the locking groove 6.30; that is, the other side of the second locking part 6.212 relative to the second locking surface 6.2121 is also constructed as a clearance slope 6.2122. Using this scheme, since the other side of the locking groove 6.30 relative to the first locking surface 6.31 is a slope, when the heating and pressing device 2' is loaded, the second locking part 6.212 elastically inserts into the locking groove 6.30 along the transition slope 6.32 as the heating and pressing device 2' is loaded. The locking process is linear, does not interfere with the loading of the heating and pressing device 2', and does not cause any bumping or jamming, resulting in a good user experience.

[0062] In other embodiments, to avoid interference with the installation of the heating and pressing device 2', the clearance recess 6.30' is constructed with a clearance slope 6.31 corresponding to the transition slope 6.32.

[0063] See Figures 7 to 11 In some embodiments of the quick-assembly and disassembly heating and pressing device 2', a pop-out mechanism 6.4 is provided. When the heating and pressing device 2' is installed in place, the pop-out mechanism 6.4 is pushed to compress and store energy. Since the heating and pressing 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 unlocking component 6.1, the pop-out mechanism 6.4 releases energy and pops the heating and pressing device 2' out of the frame 3 a certain distance, making it convenient for the user to remove, thus achieving quick installation and disassembly. On the other hand, the pop-out mechanism 6.4 can also eliminate the axial movement gap of the heating and pressing device 2', that is, the pop-out mechanism 6.4 elastically presses the heating and pressing device 2' against one side of the locking mechanism 6.

[0064] In some embodiments, the ejection mechanism 6.4 includes one or more guide members 6.41, a slider 6.42 mounted on the guide member 6.41, and a second elastic member 6.43 acting on the slider 6.42 and the one or more guide members 6.41. The heating and pressing device 2' has a push top 6.3' on its side corresponding to the slider 6.42. When the heating and pressing device 2' is installed in place, the push top 6.3' pushes the slider 6.42 to move and compress the second elastic member 6.43. Through the cooperation of the guide member 6.41, the slider 6.42, and the second elastic member 6.43, the reliability and consistency of the ejection action can be ensured, improving the smoothness and efficiency of the assembly and disassembly process.

[0065] 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 6.420'. 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.

[0066] See Figures 7 to 11 In some embodiments, one or more guide members 6.41 can be threadedly assembled onto the frame 3. For example, the end of the guide member 6.41 is constructed with a limiting structure 6.411 for a limiting second elastic member 6.43, which acts between the limiting structure 6.411 and the sliding member 6.42.

[0067] In some embodiments, the guide member 6.41 is preferably a metal part, the limiting structure 6.411 can be a boss structure with an increased diameter, the other end of the guide member 6.41 relative to the limiting structure 6.411 is provided with a threaded portion, the frame 3 is provided with a threaded hole, and the guide member 6.41 is installed by connecting with the threaded hole of the frame 3. Of course, in other embodiments, the guide member 6.41 can be assembled to the frame 3 by welding or other methods.

[0068] See Figure 7 and Figure 11 In some embodiments, the frame 3 includes a pair of spaced-apart, vertically extending support plates 301. The two support plates 301 are configured with concave regions 300' extending downwards from their upper sides. The space between the two concave regions 300' forms a heating and pressing device mounting area 300, in which a heating and pressing device 2' is inserted. Specifically, a guide member 6.41 is mounted on the inner side of one of the support plates 301 and configured adjacent to the concave region 300'.

[0069] See Figure 12 In some embodiments, the slider 6.42 is configured with a spring-loaded portion 6.420 extending to the axial movement trajectory of the pusher 6.3'. The pusher 6.3' of the heating and pressing device 2' pushes the spring-loaded portion 6.420, causing the slider 6.42 to move and compress the second elastic member 6.43. The spring-loaded portion 6.420 is configured to facilitate contact with the pusher 6.3'.

[0070] In one embodiment, the ejection mechanism 6.4 includes two guide members 6.41, with the spring-loaded portion 6.420 located between the two guide members 6.41. This arrangement ensures that the slider 6.42 is subjected to balanced forces, resulting in stable and smooth sliding, and also prevents interference between the push-top 6.3' and the two guide members 6.41.

[0071] See Figure 12 In some embodiments, the pop-out mechanism 6.4 and the movable locking member 6.2 are respectively mounted on both sides of one of the support plates 301 and configured adjacent to the concave area 300'. The movable lock body 6.21 is configured to intersect the movement direction of the spring-loaded part 6.420, preferably perpendicularly. This structure results in a small distance between the movable lock body 6.21 and the spring-loaded part 6.420, leading to good stability during locking. Furthermore, the fact that the pop-out mechanism 6.4 and the movable locking member 6.2 are respectively mounted on both sides of one of the support plates 301 makes the product layout compact and its size smaller.

[0072] In some embodiments, the movable lock body 6.21 is configured to perpendicularly intersect the direction of movement of the spring-loaded part 6.420.

[0073] See Figure 12In some embodiments, the edge of the concave region 300' of the support plate 301 is provided with a push-off clearance opening 6.30' at the position between the second locking part 6.212 and the spring-loaded part 6.420. The second locking part 6.212 extends at least partially into the push-off clearance opening 6.30. The push-off clearance slope 6.2122 of the push-top of the heating and pressing device 2' causes the second locking part 6.212 to retract inward and abut against the spring-loaded part 6.420 through the push-off clearance opening 6.30' until the locking groove 6.30 and the second locking part 6.212 are locked together.

[0074] See Figures 9 to 13 In some embodiments, a first guide feature 6.23' is provided. The first guide feature 6.23' includes a guide surface 6.231 that guides the push top 6.3' to the spring-loaded part 6.420. The configuration of the first guide feature 6.23' can ensure that when the user loads the heating and pressing device 2', the push top 6.3' engages with the spring-loaded part 6.420 without deviation or misalignment due to the gravity of the heating and pressing device 2' or other reasons.

[0075] In some embodiments, the first guide feature 6.23' is fixedly configured relative to the frame 3, such as being fixedly mounted on the support plate 301, specifically by means of connectors, welding, etc.

[0076] Of course, as Figures 9 to 13 In the illustrated embodiment, a first guide feature 6.23' is constructed on the lock seat 6.23, and the guide surface 6.231 is configured to extend obliquely upward along the loading direction of the loading heating and pressing device 2' to the height of the spring-loaded portion 6.420. This allows the push top 6.3' to contact the guide surface 6.231 and correct its position relative to the spring-loaded portion 6.420 as it is pushed, thereby ensuring that the final push top 6.3' engages with the spring-loaded portion 6.420.

[0077] Specifically, such as Figures 9 to 13 In the illustrated embodiment, the guide surface 6.231 is configured to extend obliquely upward along the loading direction of the loading heating and pressing device 2' to the push-off clearance opening 6.30.

[0078] like Figures 9 to 13 In the illustrated embodiment, at least the groove wall 6.10' adjacent to the guide feature 6.23 is provided with a second guide feature 6.101' extending axially to the push top 6.3'. With this structure, the guide distance of the loading heating and pressing device 2' can be increased by the cooperation of the guide feature with the guide surface 6.231, ensuring that the top 6.3' engages with the spring pressing part 6.420.

[0079] like Figures 9 to 13In some embodiments shown, the second guiding feature 6.101' includes an axially extending linear profile, such as a plane. Of course, in other embodiments, the cross-section of the linear profile may be arc-shaped, such as a convex arc.

[0080] In some embodiments, the first guide feature 6.23' and the lock seat 6.23 are integrally formed, such as by injection molding or machining. By integrating the first guide feature 6.23' into the lock seat 6.23, it can be assembled onto the bracket 3 along with the lock seat 6.23 without requiring separate installation, thus simplifying the assembly process and improving assembly efficiency.

[0081] See Figures 7 to 15 In some embodiments, the unlocking part 6.111 is fitted into the slide channel 6.10 and corresponds to the axial inner side of the first locking part 6.30. In response to the user pulling out the control part 6.11' and the unlocking part 6.111, it moves outward and acts on the second locking part 6.212 to achieve the unlocking operation. Using the above scheme, unlocking is achieved by pulling out the control part 6.11', which is more efficient than the user's action of removing the heating and pressing device 2'. Furthermore, by using the pull-out unlocking method, the pulling force can supplement the elastic force of the second elastic element 6.43.

[0082] See Figures 16 to 19 In one embodiment, the heater 2 includes three rigid substrates 2.0 adapted to the shape of the outer wall of the substrate s. Each substrate 2.0 includes a first substrate 2.1, a second substrate 2.2, and a third substrate 2.3. The first substrate 2.1, the second substrate 2.2, and the third substrate 2.3 are configured with pressing surfaces 204 extending between their ends. The adjacent sides of the first substrate 2.1, the second substrate 2.2, and the third substrate 2.3 are hinged to form a hot-pressing channel 200. The free sides 2.02 of the first substrate 2.1 and the third substrate 2.3, which are spaced apart and not connected, are configured to be relatively driven to adjust the heat. The size of the pressure channel 200 and the free side 2.02 of the substrate include a first free side 201 and a second free side 203. That is, it can be understood that the substrate 2.0 is driven to move by the first free side 201 and / or the second free side 203, thereby changing the inner diameter of the hot pressure channel 200, wrapping the columnar substrate s, such as a straight cup, an irregular cup with multiple outer diameters along the axial direction, etc., to achieve 360-degree heat transfer of such substrate s. The first gap formed between the two free sides 2.02 can accommodate columnar substrate s with raised structures on the surface, such as a mug with a handle, etc., thereby achieving heat transfer of such substrate s.

[0083] In other embodiments, the first substrate 2.1, the second substrate 2.2, and the third substrate 2.3 are all made of thermally conductive material, and each of the first substrate 2.1, the second substrate 2.2, and the third substrate 2.3 is provided with a heating element 2.01. Specifically, the heating element 2.01 includes a first heating element 2.11, a second heating element 2.21, and a third heating element 2.31 respectively disposed in the first substrate 2.1, the second substrate 2.2, and the third substrate 2.3.

[0084] Of course, in other embodiments, a portion of the substrates 2.0 among the first substrate 2.1, second substrate 2.2, and third substrate 2.3 can be made of thermally conductive material, and heating elements 2.01 can be configured on these thermally conductive substrates 2.0. The other portion of the substrates 2.0 can be made of non-thermally conductive material and does not require heating elements 2.01. These substrates 2.0 made of non-thermally conductive material bear the responsibility of transmitting pressure, while those made of thermally conductive material bear the responsibility of transmitting both heat and pressure. Of course, substrates 2.0 that do not require heating elements 2.01 can be made of thermally conductive material, depending on actual needs. For example, in some cases, since the location and area of ​​the pattern to be transferred on the substrate s are concentrated on a portion of the substrates 2.0, some substrates 2.0 may not need to be heated, i.e., heating elements 2.01 may not be provided. In this case, the portion of substrates 2.0 without heating elements 2.01 can be made of non-thermally conductive material, or they can all be made of thermally conductive material. For the substrate 2.0 that needs to be heated, a corresponding heating element 2.01 is configured.

[0085] Therefore, the number of heating elements 2.01 in the heater 2 of this application can be determined according to the transfer position and area requirements of the substrate s. Heating elements 2.01 can be configured only on a portion of the substrate 2.0, such as one or two of the first substrate 2.1, second substrate 2.2, and third substrate 2.3. The substrate 2.0 without heating elements 2.01 is used to hold the substrate s for heat pressing. For example, in a specific embodiment, the pattern to be transferred on the substrate s is concentrated at the positions corresponding to the first substrate 2.1 and the second substrate 2.2. Therefore, heating elements 2.01 are configured on the first substrate 2.1 and the second substrate 2.2, while the third substrate 2.3 may not have heating elements 2.01. However, the third substrate 2.3 can be made of a thermally conductive material or a non-thermally conductive material.

[0086] See Figure 20When performing heat transfer printing 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 transfer assembly s' is then loaded into the hot pressing channel 200. By driving the first free side 201 or / and the second free side 203 corresponding to the substrate 2.0, the inner diameter of the hot pressing channel 200 is reduced, thereby pressing the first substrate 2.1, the second substrate 2.2, and the third substrate 2.3 together. The surface 204 is pressed and adhered to the transfer material and the columnar substrate s by the flexible heat-conducting layer 1. 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 heat-conducting layer 1. The pressed state is maintained for a preset time (the time is specifically set according to the material of the transfer material and the heating power of the heater 2). Then, 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 taken out. The joint edge of the flexible heat-conducting layer 1 is provided with a clearance space 101, that is, the distance between at least part of the two end edges of the flexible heat-conducting layer 1 constitutes the clearance space 101. The clearance space is used to avoid the protruding structure of the substrate s, such as the handle or the connecting part of the handle on a cup.

[0087] The heater 2 of this application uses 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. A flexible heat-conducting layer 1 is used to cover the outside of the substrate s containing the transfer material to form a transfer assembly s' for heat transfer. The rigid substrate 2.0 has good structural integrity and stability, long service life, and high reliability. The flexible heat-conducting layer 1 transfers the heat and pressure of the heater 2, allowing for different thicknesses and moduli of the flexible heat-conducting layer 1 to be set according to different substrates s. This facilitates production and replacement, and is economical. The flexible heat-conducting layer 1 has good thermal conductivity and can fill and adjust the gap between the pressing surface 204 of each substrate and the substrate s covered with the transfer material, ensuring uniform heating and stress on both the transfer material and the substrate s, resulting in better heat transfer quality.

[0088] The flexible thermally conductive layer 1 is highly replaceable and economical. Since the first substrate 2.1, the second substrate 2.2, and the third substrate 2.3 are made of thermally conductive materials, they possess excellent heat storage characteristics and heat transfer efficiency, avoiding localized heating and large temperature variations at different locations that could affect temperature control and ensure heat transfer quality. Furthermore, because the flexible thermally conductive layer 1 of this application is separable from the heat-generating substrate 2.0, after the operation is completed, the flexible thermally conductive layer 1, along with the substrate s and the transfer material, detaches from the hot-pressing channel 200, thus separating from the substrate 2.0. This prevents the flexible thermally conductive layer 1 from being heated by the substrate 2.0 after the operation is completed, effectively solving the problem of odor generated by prolonged heating of the flexible substrate due to the integrated structure of the flexible substrate and the flexible heating layer in existing flexible heaters. In addition, existing heaters have flexible heating layers that are located inside the heater and in close contact with the transfer material and substrate. As a result, the temperature sensor needs to be placed separately from the flexible heating layer on the thin-walled metal shell, leading to inaccurate temperature detection. In contrast to existing heaters, the outer surface of the heater 2 in this application is directly defined by the heat-generating substrate 2.0. Therefore, the temperature detection element t can be directly mounted on the substrate 2.0 in contact, thereby effectively improving the accuracy of temperature detection.

[0089] In some embodiments, the difference between the thermally conductive material and the non-thermally conductive material referred to in the rigid substrate 2.0 of this application lies in the strength of their thermal conductivity, which can be quantified by the thermal conductivity (λ): Thermally conductive materials: such as the following metallic or non-metallic materials with a thermal conductivity ≥ 1 W / (m·K), such as metals (e.g., copper λ≈401, aluminum λ≈237), high thermal conductivity non-metals (e.g., graphene λ≈1000–5000, aluminum nitride ceramics λ≈170–280, silicon carbide λ≈120–200), etc.; Non-thermally conductive materials: such as the following non-metallic materials with a thermal conductivity < 0.12 W / (m·K), such as rock wool board (λ<0.04), polyurethane foam (λ≈0.02–0.03), vacuum insulation board (λ≈0.004), etc. That is, thermally conductive materials (λ≥1) accelerate heat transfer to dissipate heat, while non-thermally conductive materials (λ<0.12) hinder heat transfer to provide insulation.

[0090] The first substrate 2.1, the second substrate 2.2, and the third substrate 2.3 of this application 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.

[0091] 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, laid on the surfaces of the corresponding first substrate 2.1, second substrate 2.2, and third substrate 2.3, specifically integrated into one unit by die casting and embedding with the substrate 2.0. The first substrate 2.1, second substrate 2.2, and third substrate 2.3 using this scheme exhibit fast heating speed, good thermal conductivity, and better structural stability.

[0092] The flexible thermally conductive layer 1 is made of a flexible material with good thermal conductivity, such as high-temperature thermally conductive silicone. In one specific embodiment, the thermal conductivity of the flexible thermally conductive layer is ≥1. In one specific embodiment, the flexible thermally conductive layer comprises 50-70% thermally conductive material, 20-30% methyl vinyl silicone rubber, 10-20% precipitated silica, 1-3% hydroxyl silicone oil, and 0.1-0.5% internal mold release agent. The thermally conductive material consists of 60-80% silicone rubber, 20-30% thermally conductive filler, and additives (not more than 5%). The thermally conductive filler can be alumina, boron nitride, graphene, etc., and the additives are flame retardants, anti-aging agents, crosslinking agents, etc. The internal mold release agent is added to the interior of the above polymer material system to reduce the adhesion between the product and the mold, thereby reducing the application of external mold release agent and improving demolding efficiency. Its main component is an organosilicon polymer, which can form a smooth protective film on the surface of the silicone mold.

[0093] See Figures 16 to 19 In some embodiments, the heater 2 has at least a portion of the substrate 2.0 equipped with a temperature sensing element t. The temperature sensing element t is mounted in contact with the substrate 2.0 and is used to provide feedback to the control circuit of the heating element 2.01 regarding the temperature of the substrate 2.0. Furthermore, the temperature sensing element t directly contacts the substrate 2.0 for detection. Compared to the detection method of existing heaters where the temperature sensor and flexible heating layer are separated, this application offers higher temperature control accuracy, further ensuring the quality of heat transfer printing. In some embodiments, the temperature sensing element t may be an NTC temperature controller.

[0094] like Figures 16 to 19In the illustrated embodiment, 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 reduces the wiring layout; for example, the two temperature sensing elements can use three detection lines (i.e., two detection lines and one common line). Simultaneously, the first heating element 2.11, the second heating element 2.21, and the third heating element 2.31 also require only three power supply lines: the first heating element 2.11 and the third heating element 2.31 share a 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 a common power supply line (neutral wire).

[0095] Figures 16 to 19 In some embodiments, one of the two free sides 2.02 of the substrate is provided with a first connecting portion 201' and the other is provided with a second connecting portion 203'.

[0096] 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 first connecting portion 201' is used to install and fix the first free side 201, and the second connecting portion 203' is used to couple the driving device 5 and movably adjust the size of the hot pressing channel 200 relative to the first connecting portion 201' in response to the driving device 5. The heater 2 of this application is assembled on the frame 3 by connecting the first connecting portion 201' and the second connecting portion 203' to the first connecting member s10', thereby assembling the heater 2 on the frame 3 through the first connecting member s10'. Specifically, one of the first connecting members s10' is assembled to the second connecting member s20' on one side of the frame 3, and the other first connecting member s10' is assembled to the second connecting member s20' on the other side of the frame 3. 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, respectively, such as by casting or die casting, which can improve the structural strength and precision. It can be understood that when the heater 2 is installed in the hot press, its first connecting part 201' is a fixed end and the second connecting part 203' is a movable end. The heater 2 is opened and closed by driving the second connecting part 203' to move relative to the first connecting part 201' through coupling with the hot press driving mechanism of the hot press.

[0097] Regarding the number of substrates 2.0, there can be two or four or more, depending on the specific requirements. When there are two substrates 2.0, the central angle of the two sides of the pressing surface 204 of one of the substrates 2.0 along the central axis of the hot pressing channel 200 may be greater than or equal to 180 degrees. When the central angle of the pressing surface 204 of the substrate 2.0 is greater than or equal to 180 degrees, there is a tangential part between the flexible heat-conducting layer 1 and the pressing surface 204 of the substrate 2.0. Therefore, after the heater 2 is turned on, the transfer assembly s' will be stuck on the substrate 2.0 and it will be difficult to remove the transfer assembly s' from the substrate 2.0 axially. When there are four or more substrates 2.0, although the central angle of the pressing surface 204 of each substrate 2.0 will be reduced accordingly and the above-mentioned tangential phenomenon will not occur, the cost will increase due to the larger number of hinged sides. The specific configuration can be determined according to the requirements.

[0098] See Figures 16 to 19 In some embodiments, the hinge structure 2.4 of two or more substrates 2.0 includes a hinge shaft structure 2.42 disposed on the side of one substrate 2.0, and hinge seats 2.41 disposed on the sides of other adjacent substrates 2.0.
