Description

Technical Field

[0001] This utility model specifically relates to the field of heat transfer equipment technology, and more specifically to an adaptive telescopic component and heat transfer equipment. Background Technology

[0002] With the upgrading of consumption, the demand for personalized customization continues to grow. The pattern customization of products such as mobile phone cases, tablet protective cases, and small home appliance panels has become mainstream. Due to its advantages such as high efficiency, environmental protection, high pattern reproduction and controllable cost, heat transfer technology has become the core technology for personalized processing of such small-sized products and is widely used in digital accessories, home furnishings and other fields.

[0003] However, the core molds used to support and fix the products to be printed in existing heat transfer equipment still have obvious technical limitations and are difficult to adapt to the processing needs of "multi-specification, small batch" in personalized customization scenarios.

[0004] Existing thermal printing molds suffer from three major problems in practical applications: First, poor size adaptability. Most molds are of a single fixed size, requiring multiple sets of molds to be prepared separately for products of different lengths and widths (such as 5.5-inch and 6.7-inch mobile phone cases). This not only increases the cost of mold procurement and storage but also necessitates frequent mold disassembly and replacement, severely impacting processing efficiency. Some adjustable molds rely on complex structures such as bolt tightening and gear transmission, requiring repeated calibration during adjustment, which is cumbersome and results in low positioning accuracy, easily leading to product clamping misalignment. Second, insufficient heat conduction uniformity. Large gaps often exist at the joints of adjustable mold components, easily creating "discontinuities" in heat transfer. This results in insufficient heating at product edges and corners, leading to defects such as pattern color differences and blurred details, resulting in a low finished product qualification rate. Third, high overall cost. Some high-precision adjustable molds contain precision components such as micro motors and sensors, which not only makes mold opening and manufacturing difficult and costly but also requires professional operation for component replacement during later maintenance, further increasing the cost of use.

[0005] Therefore, in view of this, the present invention provides an adaptive telescopic component and a heat transfer equipment to make up for the shortcomings of the prior art in terms of size adaptation flexibility, heat conduction uniformity, operation convenience and cost control, so as to better meet the processing needs of personalized customization scenarios. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of the existing technology by providing an adaptive telescopic component and a heat transfer device to solve the related technical problems raised in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an adaptive telescopic component, including the basic support structure, a dual-axis adaptation mechanism disposed on the basic support structure, a limiting mechanism cooperating with the dual-axis adaptation mechanism, and side hook assemblies installed on the four sides of the basic support structure. The basic support structure includes four equally spaced angle plates, which together form a complete rectangular plate structure to support the product to be heat-transfer printed. The corner positioning part is detachably connected to each equally divided corner plate and is used to fit the four corner parts of the product to be heat-printed with different shapes to form a precise positioning of the product to be heat-printed. The dual-axis adaptation mechanism includes a Y-axis adaptation component arranged along the Y-axis direction and an X-axis adaptation component arranged along the X-axis direction. The Y-axis adaptation component is distributed on two opposite sides of the Y-axis of the equally bisecting angle plate, and the X-axis adaptation component is distributed on two opposite sides of the X-axis of the equally bisecting angle plate. The Y-axis adaptation component and the X-axis adaptation component work together to realize the extension and retraction adjustment of the component in the X and Y-axis directions. The limiting mechanism includes two sets of Y-axis limiting components that cooperate with the Y-axis adaptation component and two sets of X-axis limiting components that cooperate with the X-axis adaptation component. The two sets of Y-axis limiting components are symmetrically distributed on both sides of the Y-axis along with the Y-axis adaptation component, and the two sets of X-axis limiting components are symmetrically distributed on both sides of the X-axis along with the X-axis adaptation component. The Y-axis limiting components and X-axis limiting components respectively provide linear guidance and limit for the extension and retraction movements of the corresponding Y-axis adaptation component and X-axis adaptation component. Each of the equally spaced angle plates in the basic support structure is fixedly equipped with an L-shaped panel at its bottom. There are four L-shaped panels in total, which together with each equally spaced angle plate form an installation area.

[0008] Compared with the prior art, the beneficial effects of this utility model are: This adaptive telescopic component, through the coordinated linkage of the dual-axis adaptation assembly and the limiting mechanism, allows the Y-axis to slide with the Y-axis shaft and be driven by the Y-axis spring, while the X-axis relies on the linkage of the X-axis twin shafts and the X-axis spring to return to its original position. It can flexibly adapt to various length and width products to be heat-printed without the need to change the mold separately for different specifications of products. Meanwhile, the adaptive telescopic component, through the corner positioning part, can flexibly adjust and change its shape. For example, by pulling out the rounded corner part of the corner positioning part and inserting the right-angle part, the oblique part, or other shapes, the shape of the corner positioning part can be changed, thereby further improving the applicability of the telescopic component. This not only enhances the flexibility and adaptability of the telescopic component, but also improves its market competitiveness. The interlocking design between the heat-conducting plate and the equally spaced angle plate, and the tight connection between the heat-conducting cover plate and the basic support structure, ensure that there are no obvious gaps when the components expand and contract, avoid heat conduction breaks, ensure consistent heat printing effect on the surface and sides of the product, and significantly reduce the defect rate of finished products. Except for the Y-direction spring, X-direction spring, first positioning spring, and second positioning spring, all other components are made of high-temperature resistant and high thermal conductivity materials (such as aluminum alloy), which not only ensures efficient and uniform heat transfer, but also meets the rigidity requirements of heat printing processing, and avoids heat printing failure due to insufficient heat resistance or poor thermal conductivity of the material. The Y-axis channel plate and the Y-axis slide rail overlap in length, and the X-axis channel plate and the X-axis slide rail are matched with the auxiliary limit of the first positioning spring and the second positioning spring to ensure smooth sliding without deviation during dual-axis adjustment. The top planes of each component are always flush, so that the plastic film layer is heated evenly and flat, reducing the generation of wrinkles. Meanwhile, the adaptive telescopic component is composed of basic components such as equally divided angle plates, dual-axis adaptive components, and limiting mechanisms. The connection of each component is mainly through sliding fit and bolt fixing. It has no complex and precision structure, and the difficulty of mold manufacturing is low, which can effectively reduce production and maintenance costs. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Example 1: Please refer to Figures 1 to 8 As shown, an adaptive telescopic component includes a basic support structure, on which a dual-axis adaptation mechanism 2 is provided. A limiting mechanism 3 is provided on the outside of the dual-axis adaptation mechanism 2. Side hook assemblies 4 are also installed on the four sides of the basic support structure. The entire component is based on "dual-axis linkage telescopic + precise limiting + uniform heat conduction" and is used to adapt to products of different sizes to be heat-printed, such as mobile phone cases, while ensuring uniform heat transfer and stable product positioning during the heat-printing process.

[0013] The basic support structure includes four equally spaced angle plates 1. The four equally spaced angle plates 1 are spliced ​​together to form a complete rectangular plate structure. When splicing, the sides of adjacent equally spaced angle plates 1 are seamlessly aligned to form a flat top support surface, which is used to directly support the product to be heat-printed and avoid the product from tilting when placed. Each of the four equally spaced angle plates 1 has an L-shaped panel 101 fixedly installed at its bottom. The four L-shaped panels 101 enclose the corresponding equally spaced angle plates 1 to form four independent installation areas. The dual-axis adaptation mechanism 2 is installed in these installation areas. The purpose of this design is to provide dedicated installation space for the dual-axis adaptation mechanism 2. At the same time, the L-shaped panels 101 can limit the bottom of the dual-axis adaptation mechanism 2 to prevent the dual-axis adaptation mechanism 2 from moving up and down when the components expand and contract, thus ensuring the overall structural stability.

[0014] The dual-axis adaptation mechanism 2 includes a Y-axis adaptation component 2a arranged along the Y-axis direction and an X-axis adaptation component 2b arranged along the X-axis direction. The Y-axis adaptation component 2a is distributed on both opposite sides of the Y-axis of the equally bisecting angle plate 1, and the X-axis adaptation component 2b is distributed on both opposite sides of the X-axis of the equally bisecting angle plate 1. Through the linkage between the Y-axis adaptation component 2a and the X-axis adaptation component 2b, the component can be extended and retracted in both the X and Y axes, thereby adapting to products of different length and width dimensions to be heat-printed.

[0015] Specifically, the Y-axis adaptation component 2a includes a center block 21 with a hole, a Y-axis shaft 22, and two Y-axis springs 24. The center block 21 with the hole is fixed at the center of the rectangular plate. The Y-axis shaft 22 passes through the center block 21 with the hole along the Y-axis direction, forming a sliding fit. The two Y-axis springs 24 are respectively sleeved on both ends of the Y-axis shaft 22. One end of the spring abuts against the center block 21 with the hole, and the other end abuts against the equally spaced angle plates 1 on both sides of the Y-axis, which are used to provide the extension and retraction restoring force in the Y-axis direction. When an external force pushes the equally spaced angle plates 1 on both sides of the Y-axis, the Y-axis springs 24 are compressed or stretched, and can automatically reset after the external force is removed.

[0016] The Y-axis adaptation component 2a also includes two sets of Y-direction perforated strips 23. The two sets of Y-direction perforated strips 23 are symmetrically distributed on both sides of the perforated center block 21 along the Y-axis direction and are correspondingly fitted to the two Y-direction shafts 22. Each set of Y-direction perforated strips 23 has two sets of first positioning springs 231 connected to the outer walls of the two opposite ends. The other end of the first positioning spring 231 is connected to two equally spaced angle plates 1 in the X direction. Its function is to assist the Y-direction spring 24 in positioning, prevent the Y-direction shaft 22 from shifting when sliding, and maintain the stable position of the Y-direction perforated strips 23 when the component is idle.

[0017] The X-axis adaptation component 2b includes two X-axis twin shafts 25, two sets of X-axis perforated strips 26, and two X-axis springs 27. The two X-axis twin shafts 25 are symmetrically distributed on both sides of the X-axis of the equally spaced angle plate 1 along the X-axis direction. The two sets of X-axis perforated strips 26 are correspondingly inserted and fitted into the two X-axis twin shafts 25. The two X-axis springs 27 are respectively sleeved on the two X-axis twin shafts 25. One end of the spring abuts against the X-axis perforated strip 26, and the other end abuts against the fixing member at the center of the rectangular plate. It is used to provide the expansion and contraction restoring force in the X-axis direction. Its working principle is the same as that of the Y-axis spring 24.

[0018] The X-axis adaptation component 2b also includes two sets of second positioning springs 261. The two sets of second positioning springs 261 are symmetrically connected to the outer walls of the two opposite ends of the X-axis perforated strip 26, and the other end is connected to the two equally spaced angle plates 1 in the Y-axis direction. Their function is to assist the positioning of the X-axis spring 27, prevent the X-axis twin shaft rod 25 from tilting when sliding, and ensure the X-axis extension and retraction accuracy.

[0019] The limiting mechanism 3 includes two sets of Y-axis limiting components 32 and two sets of X-axis limiting components 31. The two sets of Y-axis limiting components 32 are symmetrically distributed on both sides of the Y-axis along with the Y-axis adaptation component 2a, and the two sets of X-axis limiting components 31 are symmetrically distributed on both sides of the X-axis along with the X-axis adaptation component 2b. They provide linear guidance and limiting for the extension and retraction movements of the Y-axis adaptation component 2a and the X-axis adaptation component 2b, respectively, to avoid jamming or deviation during extension and retraction.

[0020] Each Y-direction limiting component 32 includes a Y-direction channel plate 321 and a Y-direction slide rail 322. The Y-direction channel plate 321 is fixedly mounted on one of the equally bisecting angle plates 1 in the Y-direction direction, and at least half of the length of the Y-direction channel plate 321 is placed on the other equally bisecting angle plate 1 in the Y-direction direction. The Y-direction slide rail 322 is fixedly mounted on the other equally bisecting angle plate 1 in the Y-direction direction, and at least half of the length of the Y-direction slide rail 322 is placed inside the Y-direction channel plate 321 to form a sliding fit. This "length overlap" design is to ensure that the Y-direction channel plate 321 and the Y-direction slide rail 322 never disengage when the component expands or contracts, thus ensuring linear movement in the Y-axis direction.

[0021] The structure of each X-direction limiting component 31 is the same as that of the Y-direction. The X-direction channel plate 311 is fixed on one of the equally bisecting angle plates 1 in the X-direction, and at least half of its length is placed on the other equally bisecting angle plate 1 in the X-direction. The X-direction slide rail 312 is fixed on the other equally bisecting angle plate 1 in the X-direction, and at least half of its length is placed inside the X-direction channel plate 311. This is also to prevent the components from disengaging when the X-axis extends or retracts, and to ensure guiding stability.

[0022] The adaptive telescopic component also includes two heat-conducting plates 11 and two heat-conducting cover plates 12 disposed on four equally spaced angle plates 1. Several equal-distance first limiting strips 111 are symmetrically arranged on the two opposite ends of the heat-conducting plates 11. Each equally spaced angle plate 1 is provided with a second limiting strip 112 corresponding to the first limiting strip 111. The two heat-conducting plates 11 cover the X-axis areas of the rectangular plate body through the snap-fit ​​cooperation of the first limiting strip 111 and the second limiting strip 112, and can slide relative to each other as the telescopic component moves. The purpose of this design is to always cover the gap between the equally spaced angle plates 1, so as to avoid heat loss from the gap during heat printing and cause uneven heating of the product. Note: The width of the misalignment gap generated after the relative displacement of the first limiting strip 111 and the second limiting strip 112 is between 1.5mm and 3mm. The gap generated within this range can almost negligibly affect the heat conduction. In this embodiment, the gap is preferably 1.5mm to meet the best heat conduction effect.

[0023] It is worth noting that the distance of relative translation between the first limiting strip 111 and the second limiting strip 112 is adapted to the telescopic movement of the telescopic component. In other words, during the telescopic adjustment process, the first limiting strip 111 and the second limiting strip 112 are always engaged with each other and will not completely separate.

[0024] The heat-conducting cover plate 12 covers the filling heat-conducting plate 11 and is tightly connected to the equally spaced angle plate 1 via a fastening structure at the corner. The fastening structure includes a positioning protrusion 121, at least two twin sleeves 122, and two fastening bolts 123. The positioning protrusion 121 is fixedly installed at the bottom of the corner of the heat-conducting cover plate 12. The twin sleeves 122 are fixedly connected to the positioning protrusion 121. The two fastening bolts 123 are threaded into the twin sleeves 122 and pass through the equally spaced angle plate 1, thus fixing the heat-conducting cover plate 12 to the equally spaced angle plate 1. The design of the twin sleeves 122 allows the two fastening bolts 123 to be subjected to more balanced force, preventing the heat-conducting cover plate 12 from tilting due to single bolt fixation, ensuring that the heat-conducting cover plate 12 and the filling heat-conducting plate 11 are tightly fitted to form a complete heat-conducting surface and ensuring uniform heat transfer.

[0025] It is worth noting that the two heat-conducting cover plates 12 are tightly connected to the equally divided angle plate 1 through the corners on their opposite sides, so that they can move synchronously with the telescopic movement of the telescopic component. Furthermore, the coverage area of ​​the two heat-conducting cover plates 12 can completely cover the two heat-conducting plates 11, thereby further improving the heat conduction effect.

[0026] There are at least four sets of side hook assemblies 4, which correspond to the X and Y side sides of the basic support structure respectively. Each set of side hook assemblies 4 includes a heat-conducting hanging plate 41. The heat-conducting hanging plate 41 has concave hook parts at the upper and lower ends. Each equally divided angle plate 1 has a buckle groove 42 that engages with the concave hook part. The concave hook part and the buckle groove 42 can slide relative to each other.

[0027] This design ensures that the side hook assembly 4 is always connected to the basic support structure and does not detach with the expansion and contraction of the component, while also not restricting the expansion and contraction of the component; at the same time, the heat-conducting hanging plate 41 is made of a high thermal conductivity material, which can help transfer heat to the side of the product and prevent the heat-printed pattern from being lighter in color due to the side of the product being far away from the central heating area, thus ensuring that the overall heat-printing effect of the product is consistent.

[0028] It is worth noting that, among all the connecting components of the aforementioned adaptive telescopic component, except for the Y-direction spring 24, X-direction spring 27, first positioning spring 231, and second positioning spring 261 which are made of elastic metal, the remaining components, such as the equidistant angle plate 1, the heat-conducting filling plate 11, and the heat-conducting hanging plate 41, are all made of high-temperature resistant and thermally conductive materials, such as metals, like aluminum alloys. The selection of these materials serves two purposes: firstly, to ensure the component possesses excellent heat transfer performance, meeting the requirement for uniform heat transfer during heat printing; and secondly, to ensure the component has sufficient rigidity, preventing deformation during heat printing and ensuring product positioning accuracy.

[0029] One specific implementation involves filling the gap between the first limiting strip 111 of the heat-conducting plate 11 and the second limiting strip 112 of the equally spaced angle plate 1 with a clearance of ≤0.2mm to ensure that there is no significant shaking during sliding, while ensuring that heat can be transferred through the limiting strip and reducing thermal resistance; the top surface of the heat-conducting cover plate 12 is flush with the top surface of the equally spaced angle plate 1 to avoid the formation of steps that would cause uneven product placement and affect the heat printing effect.

[0030] Another embodiment of a heat transfer device includes a heat transfer device body and a mold disposed within the heat transfer device body, the mold employing the adaptive telescopic component described in the above embodiments.

[0031] It is worth noting that the main body of this heat transfer equipment is existing technology, and specific details can be found in patent application number 202422516600.5. When using this adaptive telescopic component, firstly, the component is securely installed in the working space of the heat transfer equipment main body using clamping fixtures, ensuring that the component remains horizontal with the equipment's worktable. Then, according to the size of the product to be heat-printed, such as a mobile phone case, external force is applied to the equally spaced angle plates 1 on both sides of the component's X and Y axes to adjust the component's size to match the product's inner contour. The product is then placed on the outside of the component, and the component's spring restoring force pushes the equally spaced angle plates 1 to fit tightly against the product's inner wall. Finally, a plastic film layer with the printed pattern is placed over the product, and the heat transfer equipment main body is started. The heat from the equipment's heating device is transferred to the product surface through the component's heat-conducting structure, completing the pattern heat transfer. After processing, external force is applied to the component to expand or shrink its size, and the product can then be removed.

[0032] As yet another example: like Figure 9 As shown, the aforementioned adaptive telescopic component, in addition to the basic support structure, also includes a corner positioning part; The corner positioning part is detachably connected to each equally divided corner plate 1, and is used to fit the four corner parts of the product to be heat-printed with different shapes, so as to form a precise positioning of the product to be heat-printed.

[0033] As a specific and preferred embodiment, the corner positioning part is configured as: a rounded corner positioning block 102 or a right-angle positioning block 103, note: or, as Figure 9As shown, the right-angle positioning block 103 is a positioning block with small rounded corners; the rounded corner positioning block 102 and the right-angle positioning block 103 are inserted into the corner of the equally divided angle plate 1; specifically, the bottom of the rounded corner positioning block 102 and the right-angle positioning block 103 are provided with insertion protrusions, which are tightly inserted into the corner of the equally divided angle plate 1.

[0034] Specifically, the aforementioned adaptive telescopic component, if using rounded corner positioning block 102, can be applied to products to be heat-printed with rounded corners, such as mobile phone cases or other similar products with rounded corners; if using right-angle positioning block 103, it can be applied to mobile phone cases or other similar products with right-angled corners.

[0035] In addition, the shape of the corner positioning part is not limited to the two examples listed in this embodiment. It can be selected according to the corner shape of different products, such as: obtuse angle shape, elliptical angle shape, oblique angle shape, etc. Its actual application is based on the ability to accurately position the corner parts of different shapes of different products to be heat-printed.

[0036] Note: As Figure 1 , Figure 2 As shown, the adaptive telescopic member is in its initial unadapted state, in which it is at its maximum adaptive size.

[0037] The complete usage steps and working principle of this utility model are as follows: When using this adaptive telescopic component, users must first adjust the X-axis length and Y-axis width of the component according to the length and width dimensions of the product to be heat-printed, such as a mobile phone case, to ensure that the component accurately matches the inner contour of the product. Then, the heat transfer equipment is used to complete the processing. The specific operating principle is as follows: Y-axis dimension adjustment to fit the product width: If the product to be heat-printed has width requirements, the user holds the equally spaced angle plates 1 on both sides of the Y-axis in the basic support structure with both hands, applying opposing thrusts towards the center of the component, pushing the two equally spaced angle plates 1 to slide horizontally towards each other along the Y-axis. During the sliding process, the equally spaced angle plates 1 on both sides of the Y-axis will simultaneously drive the Y-axis shaft 22 of the Y-axis adaptation component 2a to slide along the shaft hole of the center block 21; the Y-axis springs 24 sleeved at both ends of the Y-axis shaft 22 will be compressed or stretched accordingly, storing elastic potential energy, which can provide a restoring force in the Y-axis direction after the external force is removed, realizing the adaptive adjustment of the equally spaced angle plates 1.

[0038] Simultaneously, the two sets of Y-direction perforated strips 23 symmetrically distributed along the Y-axis will move synchronously with the Y-direction shaft 22. The first positioning springs 231 at both ends of the Y-direction perforated strips 23 will assist in stretching or compressing to prevent the Y-direction perforated strips 23 from shifting during sliding, ensuring the overall stability of the Y-axis adaptation component 2a. In addition, the Y-direction slide rail 322 of the Y-direction limiting component 32 will slide synchronously within the Y-direction channel plate 321. Since at least half of the length of the Y-direction channel plate 321 is placed on the other side of the equally divided angle plate 1, and at least half of the length of the Y-direction slide rail 322 is placed within the Y-direction channel plate 321, the two always maintain overlapping cooperation, ensuring that the equally divided angle plate 1 slides linearly along the Y-axis without shifting or disengaging.

[0039] When the distance between the two equally spaced angle plates 1 on both sides of the Y-axis matches the product width, the user stops applying force; at this time, the filling heat-conducting plate 11 will slide and engage with the second limiting strip 112 on the equally spaced angle plates 1 through its own first limiting strip 111, always covering the gap between the equally spaced angle plates 1, and the top plane of the filling heat-conducting plate 11 is flush with the top plane of the equally spaced angle plates 1 and the heat-conducting cover plate 12, ensuring that the top surface of the component is flat and the heat-conducting surface is complete after the Y-axis adjustment.

[0040] X-axis dimension adjustment to fit the product length: The operation is similar to the Y-axis adjustment. The user holds the two equally spaced angle plates 1 on both sides of the X-axis with both hands, applying opposing forces towards the center of the component, pushing the two equally spaced angle plates 1 to slide horizontally towards each other along the X-axis. During the sliding process, the equally spaced angle plates 1 on both sides of the X-axis will drive the X-direction perforated strip 26 of the X-axis adaptation component 2b to slide along the two X-direction double sub-shafts 25; the X-direction springs 27 sleeved on the X-direction double sub-shafts 25 are compressed or stretched accordingly, storing elastic potential energy, which can then provide a restoring force in the X-axis direction, realizing the adaptive adjustment of the equally spaced angle plates 1. At the same time, the second positioning springs 261 at both ends of the X-direction perforated strip 26 will assist in stretching or compressing to prevent the X-direction perforated strip 26 from tilting during sliding; the two X-direction double sub-shafts 25 are symmetrically distributed along the X-axis, and the integrated structure can ensure synchronous adjustment on both sides of the X-axis, further improving the motion stability of the X-axis adaptation component 2b.

[0041] In addition, the X-direction slide rail 312 of the X-direction limiting component 31 will slide synchronously within the X-direction channel plate 311. Consistent with the Y-direction limiting logic, at least half of the length of the X-direction channel plate 311 is placed on the other side of the equally divided angle plate 1, and at least half of the length of the X-direction slide rail 312 is placed within the X-direction channel plate 311. The two always overlap and cooperate to ensure that the equally divided angle plate 1 slides linearly along the X-axis without deviation or separation.

[0042] When the spacing of the equally spaced angle plates 1 on both sides of the X-axis matches the product length, the user stops applying force; at this time, the heat-conducting cover plate 12 will move synchronously with the equally spaced angle plates 1, and its top plane will still be flush with the top plane of the filling heat-conducting plate 11 and the equally spaced angle plates 1, ensuring that the top surface of the component is flat and the heat-conducting surface is complete after the X-axis adjustment.

[0043] After adjustment, it can be used in conjunction with heat transfer equipment: The user secures the component within the working space of the heat transfer equipment using clamping fixtures, ensuring the component is level and stable on the worktable. The product to be heat-printed is then placed on top of the component—the Y-axis spring 24 and X-axis spring 27 release their elastic potential energy, pushing the equally spaced angle plate 1 to fit tightly against the inner wall of the product, achieving stable product fixation without additional fixtures. Next, a plastic film layer with the printed pattern is applied to the product surface, ensuring complete adhesion and no wrinkles. Finally, the heat transfer equipment is activated, and the heat from the equipment's heating device is evenly transferred to the product surface through the heat-conducting cover plate 12 and the filling heat-conducting plate 11, completing the pattern heat transfer process.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
