Description

Technical Field

[0001] This invention belongs to the field of transfer equipment technology, and particularly relates to an open-type pressure heat transfer machine. Background Technology

[0002] Open-type pressure heat printing machines, with their three-sided open structure, make it extremely convenient to load and unload materials and observe operations. Therefore, they are particularly suitable for occasions that require frequent manual loading and unloading or for workpieces that are large in size or irregular in shape, such as garment heat transfer printing, T-shirt printing, shoe material heat transfer printing, bag embossing, leather embossing, plastic parts hot stamping, wood product branding, electronic film lamination, and stationery manufacturing. They are especially commonly used in small and medium batch production and sampling.

[0003] The biggest advantages of an open-type structure are its large operating space, convenient workpiece loading and unloading, easy observation of the hot pressing process, adaptability to larger or irregularly shaped workpieces, and relatively compact overall design, resulting in higher production efficiency. Currently, most open-type pressure heat printing machines on the market are manual, which is laborious to operate. Printing multiple garments at once can cause hand and back pain. Furthermore, the worktables are fixed, making it easy to touch and burn hands when using the machine, especially since the operator is too close to the heating plate.

[0004] In the existing technology, there are electric models of this type of product on the market. Most of them involve vertically lifting the worktable or heating plate. However, due to limitations in the motion structure and power, the stroke of this motion structure is very short. When it is opened, the gap between the heating plate and the worktable is relatively limited. In actual use, it is not clear whether the clothes and drawing paper are neatly arranged, resulting in a high defect rate of the printed patterns. Summary of the Invention

[0005] The purpose of this invention is to provide an open-type pressure heat transfer machine, which aims to solve the problems of existing electric models on the market, most of which have a vertically lifting worktable or heating plate. However, due to limitations in the motion structure and power, the stroke of this motion structure is very short, the gap between the heating plate and the worktable is relatively limited when it is opened, and in actual use, it is not clear whether the clothes and drawing paper are neatly arranged, resulting in a high defect rate of the printed pattern.

[0006] The present invention is implemented as follows: an open-type pressure heat transfer machine, the open-type pressure heat transfer machine comprising: A heat transfer device is mounted on a frame. The heat transfer device includes a placement component and a heating component. The placement component is movably connected to the frame via a sliding component. The heating component is connected to a pressure rod device. The placement component is used to place products, and the heating component is used to perform heat transfer on the products on the placement component. The sliding component is used to adjust the position of the placement component. A pressure rod device is mounted on a frame. The pressure rod device includes a pressure rod assembly and a rotating assembly. One end of the pressure rod assembly is connected to the heating assembly, and the other end is rotatably connected to one end of the rotating assembly. The other end of the rotating assembly is rotatably connected to the frame. The pressure rod device is used to drive the heating assembly to rotate, thereby adjusting the angle between the placement assembly and the heating assembly.

[0007] This invention provides an open-type pressure heat transfer machine, which includes a heat transfer device. A placement component of the heat transfer device is used to place products so that the heating component can transfer the products onto the placement component. The placement component moves via a sliding component, allowing the worktable to be pulled out of the frame, avoiding the high-temperature heating plate, increasing placement space, and improving operational convenience and safety. The heating component is connected to a pressure rod device, which uses a rotating component to cooperate with the pressure rod component, rotating to open and close the heating component. This results in a larger opening gap, and the placement component can slide to easily observe the product's placement posture, reducing the defect rate after product transfer.

[0010] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0011] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0012] like Figure 1 The diagram shown is a structural diagram of an open-type pressure heat transfer machine provided in an embodiment of the present invention. It includes: a heat transfer device 1, which is mounted on a frame 13. The heat transfer device 1 includes a placement component 11 and a heating component 12. The placement component 11 is movably connected to the frame 13 via a sliding component. The heating component 12 is connected to a pressure rod device 2. The placement component 11 is used to place a product, and the heating component 12 is used to perform heat transfer on the product on the placement component 11. The sliding component is used to adjust the position of the placement component 11. A pressure rod device 2 is mounted on the frame 13. The pressure rod device 2 includes a pressure rod assembly and a rotating assembly 23. One end of the pressure rod assembly is connected to the heating assembly 12, and the other end is rotatably connected to one end of the rotating assembly 23. The other end of the rotating assembly 23 is rotatably connected to the frame 13. The pressure rod device 2 is used to drive the heating assembly 12 to rotate, thereby adjusting the angle between the placement assembly 11 and the heating assembly 12.

[0013] In this embodiment of the invention, an open-type pressure heat transfer machine can be used to achieve pressure heat transfer of patterns on the surface of products, such as clothing, T-shirts, sweatshirts, bags, cushions, fabrics, leather, mouse pads, etc. The placement component 11 can be a worktable, tray, mat, or drawer-type support plate. The heating component 12 is used to perform heat transfer on the product on the placement component 11. The sliding component is used to adjust the position of the placement component 11, allowing it to be pulled out from the front or outside of the frame 13, or pushed back into the frame 13 and positioned. The pressure rod device 2 is used to drive the heating component 12 to rotate, thereby adjusting the angle between the placement component 11 and the heating component 12. When the pressure rod device 2 rotates up and down, the heating component 12 also moves up and down, thus forming an opening and closing working process with the worktable below. When the heating component 12 is raised, an opening is formed between the placement component 11 and the heating component 12; when the heating component 12 is pressed down, the angle between the placement component 11 and the heating component 12 decreases and they fit together, completing the pressure heat transfer.

[0014] The placement component 11 moves independently via the sliding component. During material feeding, the placement component 11 is pulled out of the frame 13, allowing the operator to clearly observe the position of the clothing and drawing paper while the heating component 12 is raised, enabling flattening, alignment, fixing, and inspection. During pressing, the placement component 11 is pushed back into the frame 13 and positioned, while the heating component 12 presses down. The combined effect of heat and pressure transfers the pattern from the drawing paper, heat transfer film, or lettering film to the product surface. When the rotating component 23 rotates around the axis of the frame 13, the pressure rod component transmits motion and force to the heating component 12, causing the heating component 12 to rotate around its own axis or hinge point. When the heating component 12 rotates upward, the angle between it and the placement component 11 increases, forming an opening; when the heating component 12 rotates downward, the angle between it and the placement component 11 decreases, ultimately pressing the product. The rotation of the rotating component 23 in the pressure rod device 2 can be manual, electric, pneumatic, or hydraulic. The control device 3 enables automatic control of temperature, time, pressure, and sliding stroke, improving production efficiency and consistency.

[0015] In one embodiment of the present invention, a heat transfer device 1 is provided. The placement component 11 of the heat transfer device 1 is used to place the product so that the heating component 12 can heat transfer the product on the placement component 11. The placement component 11 can be moved by a sliding component, which can pull the worktable out of the frame 13 to avoid the high-temperature heating plate 121, increase the placement space, and improve the convenience and safety of operation. The heating component 12 is connected to the pressure rod device 2, which can use the rotating component 23 to cooperate with the pressure rod component to drive the heating component 12 to open and close in a rotating manner. The opening gap is larger, and the placement component 11 can be slid to make it easier to see the placement posture of the product, thereby reducing the defect rate after product transfer.

[0016] like Figure 1-9As shown, in a preferred embodiment of the present invention, the placement assembly 11 includes a placement platform 111, an elastic pad 112 is provided on the top surface of the placement platform 111, a pull ring 116 is provided on the front of the placement platform 111, and the bottom surface of the placement platform 111 is connected to a sliding assembly. The sliding assembly includes a set of pulleys, namely a first pulley 113 and a second pulley 114. The first pulley 113 is provided in a set and is slidably connected to both sides of the frame 13. The first pulley 113 is fixedly connected to the bottom surface of the placement platform 111 and is used to limit the movement stroke of the placement platform 111. The second pulley component 114 is provided in a set and is slidably connected to the top surface of the frame 13. The set of second pulley components 114 is slidably connected to a set of tracks 115 on the bottom surface of the placement platform 111.

[0017] In this embodiment of the invention, the placement component 11 includes a placement platform 111. The placement platform 111 can be rectangular, square, circular, or irregularly shaped, and the material can be a rigid and high-temperature resistant material. The size of the placement platform 111 can be set according to the size of products such as clothing and bags. The bottom surface of the placement platform 111 can be provided with reinforcing ribs, folded edges, connecting brackets, or mounting plates to improve load-bearing capacity and connect with the sliding component. The elastic pad 112 can cover the entire top surface or be arranged in sections. The elastic pad 112 can be made of high-temperature resistant foam, high-temperature resistant silicone, or heat-resistant pads with raised dots. Its main function is to provide elasticity to the product after pressing down, allowing the product to adhere more evenly and tightly to the lower surface of the heating plate. The elastic pad 112 is fixed to the top surface of the placement platform 111 by adhesive, screw strips, clips, magnets, Velcro, or detachable sleeves. The elastic pad 112 also has an anti-slip function, reducing displacement of the product on its surface when pulled out, pushed back, or pressed, and increasing friction between clothing, drawing paper, and heat transfer film. Pull ring 116 can be one, two, or centrally located. Pull ring 116 can be U-shaped, D-shaped, semi-circular, or have a rubber-coated handle. The operator can pull the placement table 111 forward or push it back by holding pull ring 116. Pull ring 116 can also function as a limit handle, cooperating with the front stop block, magnetic block, or latch of frame 13 to prevent the placement table 111 from being pushed in excessively or accidentally sliding out.

[0018] The first pulley component 113 may include a wheel seat, a roller, or a buffer block. The wheel seat is fixed to the side of the bottom surface of the placement platform 111 by screws. The roller is mounted on the wheel seat by a pin and a bearing. Slots or aluminum profile slots may be provided on both sides of the frame 13. The roller is embedded in the slot and rolls in the front-back direction. When the placement platform 111 is pulled forward to a set position, the first pulley component 113 hits the front limit block, preventing the placement platform 111 from being pulled out further and avoiding it from falling off. A set of second pulley components 114 is provided, with two, four, or more, preferably one or two on each side. The second pulley components 114 are slidably connected to the top surface of the frame 13. A set of second pulley components 114 are slidably connected to a set of tracks 115 on the bottom surface of the placement platform 111. The second pulley components 114 can contact and roll with the top surface of the frame 13 via lower rollers. The top surface of the frame 13 can be equipped with a flat track 115, wear-resistant strips, steel plates, stainless steel strips, guide rails, grooves, or aluminum profile slides for the lower rollers to roll. The set of tracks 115 on the bottom surface of the placement platform 111 can be two parallel tracks 115, or a central track 115 plus auxiliary tracks 115 on both sides. The tracks 115 can be C-shaped grooves, angle steel grooves, aluminum profile grooves, or plastic wear-resistant grooves. End caps, plugs, limit screws, buffer pads, or anti-detachment pins can be installed at both ends of the tracks 115 to prevent the lower rollers from detaching. When the placement platform 111 is pulled out, a compound sliding motion is formed. When the operator pulls the pull ring 116, the track 115 on the bottom surface of the placement platform 111 slides forward relative to the second pulley component 114, and the second pulley component 114 rolls forward on the top surface of the frame 13; simultaneously, the first pulley component 113 rolls forward along the slide grooves on both sides of the frame 13. Two sets of pulleys work together to support and guide the platform 111, ensuring smooth movement and that the actual pull-out distance exceeds the travel of a single-stage slide rail. When pushed back, the rollers roll in opposite directions, and the first pulley 113 engages with the limit block for positioning.

[0019] When material needs to be placed on the placement table 111, the heating element 12 rotates upwards driven by the pressure rod device 2, creating a large opening between the placement element 11 and the heating element 12. The operator pulls the placement table 111 outwards using the pull ring 116. The first pulley 113 rolls within the sliding grooves on both sides of the frame 13, serving as a lateral guide and limiting the stroke. The second pulley 114 rolls on the top surface of the frame 13, while the bottom track 115 of the placement table 111 rolls relative to the second pulley 114, forming a two-stage sliding motion. The placement table 111 is pulled out in front of or to the outside of the frame 13, exposing the elastic pad 112, allowing the operator to clearly see the position of the clothing and drawing paper. After placement, the placement table 111 is pushed back using the pull ring 116. The first pulley 113 and the second pulley 114 roll in opposite directions, and the placement table 111 returns to the pressing position. The heating element 12 rotates downwards to press, completing the heat transfer printing. Because the first pulley 113 limits the travel, the placement platform 111 will not be pulled off; because the second pulley 114 cooperates with the track 115, the placement platform 111 is stable in bearing the load; and because of the elastic pad 112, the clothes and drawing paper are not easily moved.

[0020] like Figure 1-9 As shown, in a preferred embodiment of the present invention, the frame 13 includes a set of base rods 131 and a set of connecting plates 132. The set of base rods 131 are parallel to each other and the set of connecting plates 132 are perpendicular to each other. The base rods 131 are used to support the set of connecting plates 132. A plurality of connecting beams are provided between the set of connecting plates 132. The connecting plates 132 are L-shaped. The first connecting part of the connecting plate 132 is provided with a limiting groove 133. The limiting groove 133 is connected to the first pulley 113. The limiting groove 133 is used to limit the movement stroke of the placement platform 111. The second connecting part of the connecting plate 132 is provided with a plurality of mounting holes 134 for mounting the rotating assembly 23.

[0021] In this embodiment of the invention, the frame 13 includes a set of base rods 131 and a set of connecting plates 132. The set of base rods 131 can consist of two, four, or more rods, made of square tubing, round tubing, sheet metal bending, or castings. The base rods 131 are arranged parallel to each other, either horizontally, vertically, or in a frame shape. Foot pads, adjustable feet, shock-absorbing pads, or casters can be installed on the bottom of the base rods 131 to ensure stable placement and easy movement of the entire machine. Each set of base rods 131 is perpendicular to a set of connecting plates 132. Connection methods include welding, bolting, screwing, or quick-release buckle connections. The base rods 131 provide support, holding up the connecting plates 132 and ensuring their stable verticality or fixation above or to the side of the base rods 131. Triangular reinforcing plates, right-angle connectors, reinforcing ribs, or welded ribs can be provided between the base rods 131 and the connecting plates 132 to improve connection rigidity and load-bearing capacity. Several connecting beams are provided between the connecting plates 132. The connecting beams can be arranged horizontally or in multiple layers vertically to connect adjacent connecting plates 132. The connecting beams can be made of square tubing, sheet metal bending, or injection-molded parts. The connecting beams maintain the spacing between a group of connecting plates 132, improve the overall torsional rigidity of the frame 13, and prevent the connecting plates 132 from expanding outwards, contracting inwards, or swaying when the placement platform 111 is pulled out and pushed back. The L-shaped structure allows the connecting plates 132 to simultaneously provide lateral support and top / bottom mounting functions, resulting in high strength and a small footprint. The limiting groove 133 has a front limiting end and a rear limiting end at both ends, used to limit the travel of the placement platform 111. When the placement platform 111 is pulled outwards, the first pulley 113 moves to the front limiting end, preventing the placement platform 111 from being pulled out further and avoiding detachment. When the placement platform 111 is pushed back inwards, the first pulley 113 moves to the rear limiting end, stopping and positioning the placement platform 111. The rotating assembly 23 is installed at the mounting hole 134 of the second connecting part of the connecting plate 132. One end of the pressure rod assembly is connected to the heating element 12, and the other end is rotatably connected to the rotating assembly 23. When the rotating assembly 23 rotates around the axis of the frame 13, the pressure rod assembly causes the heating element 12 to be raised or lowered.

[0022] like Figure 1-9As shown, in a preferred embodiment of the present invention, the rotating assembly 23 includes a rotating power component 231 and a rotating transmission component 232. The rotating power component 231 is installed on the side of the second connecting portion of the connecting plate 132 of the frame 13. The output end of the rotating power component 231 passes through the second connecting portion and is connected to the rotating transmission component 232 for transmission. The rotating transmission component 232 is connected to the pressure rod assembly and is used to drive the pressure rod assembly to rotate.

[0023] In this embodiment of the invention, the rotating power component 231 can be an electric push rod, a servo motor, a stepper motor, a geared motor, or a manual gear mechanism. Preferably, an electric push rod or servo motor is used in conjunction with a reducer to facilitate control of the opening and closing angle, speed, and pressing time. The rotating power component 231 is mounted on the side of the second connecting portion of the connecting plate 132 of the frame 13. A mounting seat, flange plate, or motor mount can be provided on the side of the second connecting portion. The rotating power component 231 is fixed to the side of the second connecting portion by bolts, screws, flanges, brackets, or quick-release structures. The mounting position can be adjusted vertically, horizontally, or angularly to accommodate different sizes of heating components 12 and different opening angle requirements. The second connecting portion can be provided with a through hole, a bushing hole, or a protective sleeve hole. The output end can be a rotating shaft, an output shaft, or a splined shaft. The transmission connection method can be direct connection, coupling connection, or gear meshing. When the rotating power component 231 is an electric push rod, the electric push rod seat is fixed to the side of the second connecting portion, the push rod end passes through the through hole of the second connecting portion, and is hinged to one end of the swing arm. The other end of the swing arm is fixed to a rotating shaft, which is mounted inside the frame 13 via a bearing housing. The rotating shaft is then connected to the pressure rod assembly. When the electric push rod extends or retracts, the swing arm rotates around the rotating shaft, and the pressure rod assembly rotates accordingly.

[0024] like Figure 1-9 As shown, in a preferred embodiment of the present invention, the pressure rod assembly includes a first pressure rod assembly 21 and a second pressure rod assembly 22. The first pressure rod assembly 21 and the second pressure rod assembly 22 are rotatably connected to the connecting plate 132 of the frame 13, respectively. The first pressure rod assembly 21 and the second pressure rod assembly 22 are slidably connected. The first pressure rod assembly 21 includes a first upper pressure rod 211 and a second upper pressure rod 212. The first upper pressure rod 211 is provided with a first sliding groove 216. The first upper pressure rod 211 is connected to the rotational transmission member 232 through a first connecting member 213. The first connecting member 213 is disposed in the first sliding groove 216. The first sliding groove 216 is used to limit the sliding stroke of the first upper pressure rod 211. The first upper pressure rod 211 is rotatably connected to the second upper pressure rod 212 through a set of first rotating shafts 214. The second upper pressure rod 212 is slidably connected to the second pressure rod assembly 22 through a first rolling shaft 215.

[0025] In this embodiment of the invention, after the rotational power component 231 is activated, its output end drives the rotational transmission component 232 to move. The rotational transmission component 232 drives the first connecting component 213 to move. The first connecting component 213 rolls or slides within the first groove 216 of the first upper pressure rod 211. The first groove 216 restricts the sliding stroke of the first upper pressure rod 211, causing the first upper pressure rod 211 to move or swing along a set trajectory. The first upper pressure rod 211 drives the second upper pressure rod 212 to swing through a set of first rotating shafts 214. The first rolling shaft 215 at the end of the second upper pressure rod 212 enters the second groove 223 on the second pressure rod assembly 22 and rolls or slides along the second groove 223. When the first rolling shaft 215 moves within the second groove 223, the sidewall of the second groove 223 generates a thrust on the first rolling shaft 215, causing the second pressure rod assembly 22 to rotate around the second rotating shaft. When the second pressure rod assembly 22 rotates around the second rotating shaft, the front end of the lower pressure rod 221 moves downward or upward. The front end of the pressure rod 221 is connected to the control device 3 of the heating element 12, and the control device 3 moves with the heating element 12. The bottom surface of the pressure rod 221 is connected to the pressure rod bracket 222, and the pressure rod bracket 222 is connected to the top surface of the heating element 12. When the front end of the pressure rod 221 is downward, the pressure rod bracket 222 transmits pressure to the top surface of the heating element 12, and the heating element 12 rotates downward and presses the product on the placement table 111. When the front end of the pressure rod 221 is upward, the pressure rod bracket 222 or the return component drives the heating element 12 to rotate upward, forming a larger opening between the heating element 12 and the placement table 111. The operator can pull out the placement table 111 through the pull ring 116 to clearly observe the placement of the clothes and drawing paper, adjust and align them, and then push them back to press them together. The first slide groove 216 cooperates with the first connecting piece 213 to limit the sliding stroke of the first upper pressure rod 211. The second slide groove 223 cooperates with the first rolling shaft 215 to limit the sliding stroke of the second upper pressure rod 212. The two sets of sliding grooves work together to make the opening and closing angle and pressing stroke of the heating element 12 controllable. The first upper pressing rod 211, the second upper pressing rod 212, the lower pressing rod 221 and the pressing rod bracket 222 form a multi-link lever mechanism, which can convert the motion of the rotating transmission component 232 into the up and down rotation of the heating element 12 and generate a force amplification effect, so that the pressing of the heating element 12 is stable.

[0026] The first rotating shaft 214 can be a pin, a smooth shaft, or a bearing shaft. Bearings, bushings, wear-resistant sleeves, or lubrication holes can be provided at the first rotating shaft 214. The first upper pressure rod 211 and the second upper pressure rod 212 can form an angle, which changes with the movement of the first rotating shaft 214. When the first upper pressure rod 211 moves or swings, it pushes or pulls the second upper pressure rod 212 through the first rotating shaft 214, causing the second upper pressure rod 212 to swing. The first rolling shaft 215 can include a roller shaft, a pin, or a bearing shaft. The end of the first rolling shaft 215 enters the sliding track 115 or the second slide groove 223 on the second pressure rod assembly 22, rolling or sliding along the sliding track 115 or the second slide groove 223. Bearings, rollers, or wear-resistant bearing sleeves can be provided at the first rolling shaft 215 to ensure smooth movement and reduce noise. like Figure 1-7 As shown, in a preferred embodiment of the present invention, the second pressure rod assembly 22 includes a lower pressure rod 221 and a pressure rod bracket 222. The lower pressure rod 221 is rotatably connected to the connecting plate 132 of the frame 13 via a second rotating shaft. A second sliding groove 223 is provided on the side of the lower pressure rod 221. The second sliding groove 223 is used to limit the sliding stroke of the second upper pressure rod 212. The front end of the lower pressure rod 221 is connected to the control device 3 of the heating component 12. The bottom surface of the lower pressure rod 221 is connected to the pressure rod bracket 222. The pressure rod bracket 222 is connected to the top surface of the heating component 12.

[0027] In this embodiment of the invention, after the rotational power component 231 is activated, its output end passes through the second connecting portion of the connecting plate 132 of the frame 13, driving the rotational transmission component 232 to move. The rotational transmission component 232 drives the first connecting component 213 to move. The first connecting component 213 slides or rolls within the first sliding groove 216 of the first upper pressure rod 211. The first sliding groove 216 restricts the sliding stroke of the first upper pressure rod 211. The first upper pressure rod 211 drives the second upper pressure rod 212 to swing through the first rotating shaft 214. The first rolling shaft 215 at the end of the second upper pressure rod 212 enters the second sliding groove 223 on the side of the lower pressure rod 221. When the first rolling shaft 215 moves within the second sliding groove 223, the side wall of the second sliding groove 223 generates a thrust on the first rolling shaft 215, causing the lower pressure rod 221 to rotate around the second rotating shaft. The two ends of the second sliding groove 223 are limited, restricting the rotation angle of the lower pressure rod 221, thereby limiting the opening and closing angle and pressing stroke of the heating component 12. When the pressure rod 221 rotates around the second rotation axis, its front end moves downward or upward. The front end of the pressure rod 221 is connected to the control device 3 of the heating element 12, and the control device 3 moves with the heating element 12. The bottom surface of the pressure rod 221 is connected to the pressure rod bracket 222, which is connected to the top surface of the heating element 12. When the front end of the pressure rod 221 moves downward, the pressure rod bracket 222 transmits pressure to the top surface of the heating element 12, causing the heating element 12 to rotate downward and press against the product on the placement table 111. When the front end of the pressure rod 221 moves upward, the pressure rod bracket 222 or the return mechanism drives the heating element 12 to rotate upward, forming a larger opening between the heating element 12 and the placement table 111.

[0028] like Figure 8-9 As shown, in another preferred embodiment of the present invention, the pressure rod assembly includes a first pressure rod 24 and a second pressure rod 25. The first pressure rod 24 is provided with a third sliding groove. The first pressure rod 24 is connected to the rotation transmission member 232 through a second connecting member. The third sliding groove is used to limit the sliding stroke of the first pressure rod 24. The first pressure rod 24 is rotatably connected to the second pressure rod 25 through a third rotating shaft. The second pressure rod 25 is rotatably connected to the connecting plate 132 of the frame 13 through a fourth rotating shaft. The front end of the second pressure rod 25 is connected to the control device 3 of the heating element 12. The bottom surface of the second pressure rod 25 is connected to the pressure rod bracket 222. The pressure rod bracket 222 is connected to the top surface of the heating element 12.

[0029] In this embodiment of the invention, after the rotational power component 231 is activated, its output end drives the rotational transmission component 232 to move. The rotational transmission component 232 drives the second connecting component to move. The second connecting component rolls or slides within the third groove of the first pressure rod 24. The third groove limits the sliding stroke of the first pressure rod 24, causing the first pressure rod 24 to move or swing along a set trajectory. The first pressure rod 24 pushes and pulls the second pressure rod 25 via the third rotational shaft. The second pressure rod 25 rotates around the fourth rotational shaft. The fourth rotational shaft acts as a fulcrum, causing the second pressure rod 25 to form a lever. The front end of the second pressure rod 25 moves downward or upward. The front end of the second pressure rod 25 drives the control device 3 of the heating element 12 to move. The bottom surface of the second pressure rod 25 drives the pressure rod bracket 222 to move. The pressure rod bracket 222 transmits force to the top surface of the heating element 12. The heating element 12 presses downward or lifts upward around its own rotational axis or hinge point. When the heating element 12 is lifted upwards, the front end of the second pressure rod 25 faces upwards, and the pressure rod bracket 222 drives the top surface of the heating element 12 upwards, forming a large opening between the heating element 12 and the placement table 111. The operator can pull out the placement table 111 through the pull ring 116 to clearly see whether the clothes and drawing paper are aligned. When the heating element 12 is pressed downwards, the front end of the second pressure rod 25 faces downwards, and the pressure rod bracket 222 presses down on the top surface of the heating element 12, and the heating plate 121 adheres to the product. Heat and pressure work together to complete the pattern transfer. The third slide groove cooperates with the second connector to limit the pressing stroke and avoid overpressure; the fourth rotating shaft cooperates with the second pressure rod 25 to form a lever to increase force and make the pressing stable; the pressure rod bracket 222 can distribute the pressure so that the heating plate 121 is evenly stressed.

[0030] like Figure 1-9 As shown, in a preferred embodiment of the present invention, the heating component 12 includes a control device 3 and a heating plate 121. The control device 3 is electrically connected to the heating plate 121. The control device 3 is provided with a display screen 31 and several buttons 32. The display screen 31 is used to display the status of the heating plate 121, and the buttons 32 are used to control the switching on and off of the heating plate 121 and to adjust the temperature.

[0031] In this embodiment of the invention, when the operator presses the power button, the control device 3 powers on the heating element 12 of the thermal printing device 1, the main control board starts up, and the display screen 31 shows the current temperature, the set temperature, or the standby status. The operator inputs the target temperature using the heating button, cooling button, or setting button. The main control board reads the signal from button 32 and compares the set temperature with the temperature detected by the temperature sensor. When the detected temperature is lower than the set temperature, the temperature control module outputs a control signal, the solid-state relay is turned on, and the heating plate 121 is powered on for heating. When the detected temperature reaches the set temperature, the temperature control module controls the solid-state relay to turn off or reduce the power, so that the heating plate 121 enters the heat preservation state. When the detected temperature falls below the set temperature again, heating is restarted. This cycle continues, keeping the temperature of the heating plate 121 within the set range.

[0032] The display screen 31 shows the real-time status of the heating plate 121. During heating, a heating indicator or red backlight is displayed. During heat preservation, a heat preservation indicator or green backlight is displayed. In case of a fault, a fault code is displayed, such as sensor open circuit, sensor short circuit, overheating, overcurrent, undervoltage, or communication abnormality. Several buttons 32 control the heating plate 121's on / off state and temperature adjustment. The power button is used to turn heating on or off. The heating and cooling buttons are used to increase or decrease the set temperature. The setting and confirmation buttons are used to set the time, pressure, mode, language, brightness, and temperature unit. The emergency stop button is used to cut off the heating power in an emergency.

[0033] The heating element 12 works in conjunction with the pressure rod device 2 and the placement component 11. When the heating element 12 rotates upward, a larger opening is formed between the placement platform 111 and the heating plate 121. The operator pulls out the placement platform 111 via the pull ring 116, lays the garment flat on the elastic pad 112, places the drawing paper or heat transfer film, and observes the alignment. After pushing the placement platform 111 back, the pressure rod device 2 drives the heating element 12 to rotate downward, and the heating plate 121 presses down on the product. The control device 3 completes the heating transfer according to the set temperature and time. The display screen 31 can display the countdown and temperature status, allowing the operator to monitor the transfer progress.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
