Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, and more specifically, to an automatic transfer device for patterns on the surface of metal badges. Background Technology

[0002] In the metal products processing industry, metal badges are widely used in corporate promotion, event commemoration, and gift customization due to their multiple functions such as identification, commemoration, and decoration. In the metal badge manufacturing industry, to meet diverse appearance design needs, badges with curved surfaces (such as convex circular badges and commemorative badges with curved edges) are widely used in badge customization, honorary medals, and brand commemorative gifts because they have a stronger visual three-dimensionality and tactile feel.

[0003] Traditional flat transfer printing devices have a rigid planar pressing structure, which is only suitable for flat badge transfer. When used for badges with curved surfaces, the flat pressing head cannot adaptively fit the curved contour of the badge: the center of the pressing head first contacts the top of the convex surface of the badge and applies pressure, while there is a gap between the edge of the pressing head and the curved edge of the badge. As the pressure increases, the transfer paper will be stretched from the center to the edge, forming wrinkles in the gap area. This results in "faults" or "blurred bands" corresponding to the wrinkles in the transferred pattern, and serious loss of pattern details. Based on the above problems, we propose an automatic transfer printing device for patterns on the surface of metal badges. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an automatic transfer device for the surface pattern of metal badges. This solves the problem that in the traditional transfer device, the transfer paper and the curved surface of the workpiece are not easy to adhere to each other during the processing, resulting in gaps and wrinkles on the surface of the transfer paper during the transfer process, causing the loss of pattern details.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic transfer printing device for surface patterns on metal badges, comprising a frame assembly, a pressure-bearing assembly, and a transfer printing assembly; both the pressure-bearing assembly and the transfer printing assembly are disposed on the top of the frame assembly, with the transfer printing assembly located above the pressure-bearing assembly; the pressure-bearing assembly includes a motor disposed at the bottom of the frame assembly, a turntable disposed at the top output end of the motor, a pressure-bearing seat disposed at the top of the turntable, a workpiece to be processed disposed inside the pressure-bearing seat, transfer paper disposed on the top of the workpiece to be processed, and a raised ring disposed at the bottom of the turntable; the transfer printing assembly includes a top frame disposed in the middle of the top of the frame assembly, a cylinder disposed in the middle of the top of the top frame, a lifting seat disposed at the output end of the cylinder, a hot pressing seat disposed at the bottom of the lifting seat, a smoothing air passage disposed on the inner edge of the hot pressing seat, and a fan disposed on one side of the top of the top frame, with the output end of the fan connected to the smoothing air passage via a pipe; During the transfer process, the cylinder drives the hot press seat to move downwards. When the hot press seat approaches the pressure seat, the fan blows a smoothing airflow onto the transfer paper through the smoothing air passage. At this time, the transfer paper adheres to the top surface of the workpiece to be processed.

[0006] Preferably, the frame assembly includes a processing table, the processing table has a movable groove in the middle of its top, and a convex ring extends into the movable groove. The movable groove is also provided with an ejection mechanism, which includes a hinge frame disposed inside the movable groove, a crank arm disposed on the surface of the hinge frame, a spring disposed at the bottom of one end of the crank arm near the convex ring, and a push rod disposed at the other end of the crank arm.

[0007] Preferably, the crank arm is S-shaped and when the protrusion of the convex ring contacts one end of the crank arm, it squeezes the crank arm. At this time, the other end of the crank arm flips upward along the hinge frame, and the top rod extends into the bearing seat.

[0008] Preferably, the bottom of the smoothing air passage is inclined outward, the bottom of the convex ring is wavy, and the bottom of the pressure seat is provided with an ejection hole that cooperates with the push rod.

[0009] Preferably, the top of the workpiece to be processed is arc-shaped, and the bottom of the hot press base is provided with an arc-shaped groove that matches the workpiece to be processed, and the curvature of the arc-shaped groove is the same as the curvature of the top of the workpiece to be processed.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model designs a pressure-bearing component and a transfer component. Smoothing air channels are evenly distributed along the inner edge of the hot press base, with the bottom of these channels sloping outwards. These channels are connected to the output of a blower via pipes. During the transfer process, a cylinder drives the hot press base downwards. As the hot press base approaches the pressure-bearing component, the blower delivers smoothing airflow to the transfer paper through the smoothing air channels. At this point, the transfer paper adheres to the top surface of the workpiece. The airflow expels the air between the transfer paper and the workpiece surface, ensuring a tight fit and effectively solving the problem of wrinkles in traditional devices, thus improving the quality of the pattern transfer. The bottom of the hot press base has an arc-shaped groove with the same curvature as the top of the workpiece, achieving a perfect fit between the hot press base and the arc-shaped badge surface. This avoids gaps caused by rigid flat pressure heads, further ensuring the adhesion of the transfer paper and ensuring even pressure and heat transfer, guaranteeing a uniform and secure pattern transfer.

[0011] 2. This utility model further designs the frame assembly and the pressure-bearing assembly by setting a convex ring at the bottom of the turntable, with the bottom of the convex ring being wavy. When the turntable drives the pressure-bearing seat to rotate and replace, it can drive the convex ring to rotate synchronously. During the rotation of the convex ring, when the protrusion of the convex ring contacts one end of the curved arm, it squeezes the curved arm. At this time, the other end of the curved arm flips upward along the hinge frame, and the top rod extends into the inside of the pressure-bearing seat, lifting up the transferred badge. There is no need for manual removal, which improves the convenience and efficiency of picking up the parts and reduces the labor intensity of the operators. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments: This utility model relates to an automatic transfer device for patterns on the surface of metal badges, comprising a frame assembly 1, a pressure-bearing assembly 2, and a transfer assembly 3; both the pressure-bearing assembly 2 and the transfer assembly 3 are fixedly connected to the top of the frame assembly 1, with the transfer assembly 3 located above the pressure-bearing assembly 2; the pressure-bearing assembly 2 includes a motor 201 fixedly connected to the bottom of the frame assembly 1, a turntable 202 fixedly connected to the top output end of the motor 201, and a pressure seat 203 fixedly connected to the top of the turntable 202. The interior contains a workpiece 2031 to be processed, with transfer paper 2032 laid on top of the workpiece 2031. A convex ring 204 is fixedly connected to the bottom of the turntable 202. The motor 201 drives the turntable 202 to rotate around its own axis through the top output end, realizing the switching of the pressure seat 203 between "loading station → transfer station → part removal station", replacing manual handling and improving the efficiency and accuracy of station switching. The turntable 202, in conjunction with the motor 201, achieves multi-station cyclic operation, bearing pressure. The base 203 serves as a positioning container for the workpiece 2031 to be processed. Its internal shape is adapted to the bottom of the badge to be processed, ensuring that the badge will not shift or wobble after placement. This provides a stable reference for the accurate coverage of the transfer paper 2032 and subsequent hot-press bonding. The workpiece 2031 to be processed is the object of the device, namely the arc-shaped metal badge with the pattern to be transferred. Its top arc structure is the core target of the transfer, which needs to be positioned by the pressure base 203 and adapted by the transfer component 3 to ensure that the pattern is accurately transferred to its surface. The transfer paper 2032 serves as the carrier of the pattern, with the pattern to be transferred printed on its surface. After covering the top of the workpiece 2031 to be processed, the ink is transferred to the surface of the badge by the heat and pressure of the hot press seat 304. It is the key medium for pattern transfer. The protruding ring 204 serves as the trigger of the ejection mechanism 103. When it rotates with the turntable 202, its protrusion will periodically squeeze one end of the crank arm 1032, forcing the crank arm 1032 to rotate around the hinge frame 1031, thereby driving the push rod 1034 to lift the badge.The transfer assembly 3 includes a top frame 301 fixedly connected to the center of the top of the frame assembly 1. A cylinder 302 is fixedly connected to the center of the top of the top frame 301. A lifting seat 303 is fixedly connected to the output end of the cylinder 302. A hot press seat 304 is fixedly connected to the bottom of the lifting seat 303. A smoothing air passage 3042 is provided on the inner edge of the hot press seat 304. A fan 305 is fixedly connected to one side of the top of the top frame 301, and the output end of the fan 305 is connected to the smoothing air passage 3042 through a pipe. The top frame 301 provides a stable mounting surface for the cylinder 302 and the fan 305. The cylinder 302 is aligned with the pressure seat 203 to prevent the hot press seat 304 from shifting and causing misalignment during transfer. The cylinder 302, through the extension and retraction of its output end, moves the lifting seat 303 and the hot press seat 304 up and down. When extended, it pushes the hot press seat 304 downwards to adhere to the transfer paper 2032 and the badge, providing the necessary pressure for transfer. The lifting seat 303 supports the hot press seat 304, ensuring it remains horizontal during lifting and lowering to prevent uneven pressure due to tilting. The hot press seat 304 provides heat for the sublimation of the ink on the transfer paper 2032, transferring the pattern to the badge. On the surface of the badge, the smoothing air passage 3042 allows the airflow delivered by the blower 305 to be precisely directed towards the edge of the transfer paper 2032. The airflow diffuses along the surface of the transfer paper 2032 towards the center, expelling the air between the transfer paper 2032 and the badge. The blower 305 delivers a stable airflow to the smoothing air passage 3042 through a pipe. This utility model, through the design of the pressure-bearing component 2 and the transfer component 3, uses smoothing air passages 3042 evenly arranged on the inner edge of the hot press base 304, with the bottom of the smoothing air passage 3042 inclined outwards. Simultaneously, the smoothing air passage 3042 is connected to the blower 305 through a pipe. The output end of 5 is connected. During the transfer process, cylinder 302 drives the hot press seat 304 to move downwards. When the hot press seat 304 approaches the pressure seat 203, the fan 305 blows a smoothing airflow onto the transfer paper 2032 through the smoothing air passage 3042. At this time, the transfer paper 2032 adheres to the top surface of the workpiece 2031 to be processed. The airflow can expel the air between the transfer paper 2032 and the surface of the workpiece 2031 to be processed, making the transfer paper 2032 adhere tightly. This effectively solves the problem of wrinkles easily generated on the transfer paper 2032 in traditional devices and improves the quality of pattern transfer.

[0015] Specifically, the frame assembly 1 includes a processing table 101. A movable groove 102 is formed in the center of the top of the processing table 101, and a convex ring 204 extends into the movable groove 102. An ejection mechanism 103 is also fixedly connected inside the movable groove 102. The ejection mechanism 103 includes a hinge frame 1031 fixedly connected inside the movable groove 102, a crank arm 1032 rotatably connected to the surface of the hinge frame 1031, and a spring 1 fixedly connected to the bottom of the crank arm 1032 near the bottom of the convex ring 204. 033. A push rod 1034 is fixedly connected to the other end of the crank arm 1032. The hinge frame 1031 limits the rotation trajectory of the crank arm 1032, ensuring that the crank arm 1032 can rotate around the fixed axis when subjected to force, avoiding deviation. The crank arm 1032 utilizes the lever arm advantage of the S-shaped structure to convert the compressive force of the convex ring 204 into the upward pushing force of the push rod 1034, realizing the direction and amplification of force. After the spring 1033 leaves the crank arm 1032 at the protrusion of the convex ring 204, it pushes the crank arm 1032 through its own elasticity. Arm 1032 resets, causing push rod 1034 to retract, preparing for the next ejection action and ensuring the cyclical operation of ejection mechanism 103. Driven by the curved arm 1032, push rod 1034 extends into ejection hole 2033 of pressure seat 203, lifting the transferred badge upwards. This invention further designs the frame assembly 1 and pressure assembly 2 by providing a convex ring 204 at the bottom of turntable 202, with the bottom of the convex ring 204 having a wavy shape. While the moving pressure seat 203 rotates and replaces, it can drive the convex ring 204 to rotate synchronously. During the rotation of the convex ring 204, when the protrusion of the convex ring 204 contacts one end of the curved arm 1032, it squeezes the curved arm 1032. At this time, the other end of the curved arm 1032 flips upward along the hinge frame 1031, and the push rod 1034 extends into the inside of the pressure seat 203 to lift up the transferred badge. There is no need for manual removal, which improves the convenience and efficiency of picking up the badge and reduces the labor intensity of the operator.

[0016] Specifically, the crank arm 1032 is S-shaped. When the protrusion of the convex ring 204 contacts one end of the crank arm 1032, it squeezes the crank arm 1032. At this time, the other end of the crank arm 1032 flips upward along the hinge frame 1031, and the push rod 1034 extends into the bearing seat 203. By utilizing the lever arm advantage of the S-shaped structure, the squeezing force of the convex ring 204 is converted into the upward pushing force of the push rod 1034, thus realizing the direction and amplification of the force.

[0017] It is worth mentioning that the bottom of the smoothing air passage 3042 is inclined outward, so that the airflow delivered by the blower 305 can be accurately blown to the edge of the transfer paper 2032, rather than directly to the center. The bottom of the convex ring 204 is wavy, which provides a periodic trigger signal for the ejection mechanism 103 to realize the automatic ejection of the badge after transfer. The bottom of the pressure seat 203 is provided with an ejection hole 2033 that cooperates with the ejector rod 1034, and the ejection hole 2033 provides space for the ejector rod 1034 to pass through.

[0018] It is worth noting that the top of the workpiece 2031 to be processed is arc-shaped, and the bottom of the hot press base 304 is provided with an arc-shaped groove 3041 that matches the workpiece 2031 to be processed. The curvature of the arc-shaped groove 3041 is the same as the curvature of the top of the workpiece 2031 to be processed. The arc-shaped groove 3041 with the same curvature as the top of the workpiece 2031 to be processed is provided at the bottom, so as to achieve arc-shaped fitting, avoid the gap problem of traditional flat pressure head, and ensure that pressure and heat are evenly transferred to the transfer paper 2032.

[0019] Working Principle: This embodiment provides an automatic transfer printing device for patterns on the surface of metal badges. During use, the operator places the workpiece 2031 to be processed inside the pressure seat 203, ensuring the bottom of the badge is stably attached to the inner wall of the pressure seat 203. Then, transfer paper 2032 with the specified pattern is placed over the top arc-shaped surface of the workpiece 2031, completing the loading process. The device is then powered on, and the motor 201 drives the turntable 202 to rotate, transferring the pressure seat 203 containing the workpiece 2031 to directly below the hot press 304. Simultaneously, the heating element inside the hot press 304 is activated, starting to heat up to the set temperature, while the fan 305 remains in standby mode. When the pressure seat 203 reaches the designated position, the motor 201 stops rotating, the cylinder 302 starts, and its output end extends downward, driving the lifting seat 303 and the hot press seat 304 to move downward synchronously; when the bottom of the hot press seat 304 approaches the surface of the transfer paper 2032, the fan 305 starts, delivering airflow through the pipe to the smoothing air passage 3042 inside the hot press seat 304. The airflow is blown towards the edge of the transfer paper 2032 through the inclined outlet at the bottom of the smoothing air passage 3042, and diffuses along the surface of the transfer paper 2032 towards the center, expelling the air between the transfer paper 2032 and the top arc surface of the workpiece 2031, so that the transfer paper 2032 is in a state of air Under the influence of airflow, the transfer paper adheres tightly to the surface of the workpiece 2031, preventing wrinkles. As the cylinder 302 continues to extend, the hot press 304 continues to move downward until the arc-shaped groove 3041 at the bottom of the hot press 304 is in complete contact with the transfer paper 2032. At this point, the hot press 304 applies stable pressure to the transfer paper 2032 and the workpiece 2031, while the heat from the hot press 304 is transferred to the transfer paper 2032, causing the pattern ink on the transfer paper 2032 to sublimate and transfer to the surface of the workpiece 2031. Maintaining this state completes the pattern transfer. After the transfer is completed, the output end of the cylinder 302 retracts, driving the hot press 304 upward. Reset; Motor 201 restarts, driving turntable 202 to rotate, rotating the pressure seat 203 that has completed the transfer out from under the hot press seat 304; During the rotation of turntable 202, the protrusion of the convex ring 204 at the bottom of turntable 202 gradually contacts one end of the crank arm 1032 of the ejection mechanism 103, and squeezes the crank arm 1032, causing the crank arm 1032 to rotate around the hinge frame 1031, and the other end of the crank arm 1032 flips upward, and the push rod 1034 extends into the inside of the pressure seat 203 through the ejection hole 2033 at the bottom of the pressure seat 203, lifting the metal badge that has completed the transfer, so that the operator can easily take out the badge, completing the entire transfer process.
