Description

Technical Field

[0001] This invention relates to the field of heat transfer equipment, specifically to a dual-station offset-free heat transfer device for toy cups. Background Technology

[0002] Currently, in the field of heat transfer printing for toy cups, most commonly used production equipment adopts a single-station structure, that is, cup feeding, heat transfer printing and unloading are completed step by step in the same station or on a single production line. There is waiting time between each process, resulting in low equipment utilization, low production efficiency, and difficulty in meeting the needs of continuous mass production.

[0003] Meanwhile, in existing cup transfer printing equipment, the cup is typically positioned by a mounting mold on the transfer plate during the heat transfer process, lacking an effective support and limiting structure for the cup bottom. When the transfer roller applies rotational pressure and friction to the outer wall of the cup, the cup is prone to axial movement or radial displacement, leading to problems such as deviation in the position of the transferred pattern and pattern stretching and deformation, which seriously affects the appearance quality and printing consistency of the product.

[0004] Furthermore, many toy cups often have a tapered or sloping surface to meet diverse design requirements. However, the film holder angle of traditional transfer printing devices is fixed and cannot be adjusted to adapt to the shape of the cup. This makes it difficult for the transfer film to adhere tightly to the sloping cup surface, easily causing wrinkles or blurred patterns on curved areas, thus limiting the equipment's ability to process irregularly shaped cups. Summary of the Invention

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0019] Example A dual-station, offset-free heat transfer device for toy cups, such as Figure 1-8 As shown, it includes a base 1, a cup inlet belt 2 and a cup outlet belt 3 fixedly installed above the front end of the base 1 and parallel to each other, a dual-station cup lifting and lowering mechanism 4 fixedly installed above the front end of the base 1 and located between the cup inlet belt 2 and the cup outlet belt 3, a support base 5 fixedly installed above the base 1, a transfer rotary disk 6 installed on one side of the support base 5 and facing the dual-station cup lifting and lowering mechanism 4, a column frame 7 fixedly installed above the support base 5, a rotating film frame 8 installed in front of the column frame 7 and capable of rotation and swinging, and a heat transfer mechanism 9 installed in front of the column frame 7 and operating in conjunction with the transfer rotary disk 6 and the rotating film frame 8.

[0020] Specifically, through the compact layout and coordinated operation of various functional modules, a complete fully automated heat transfer production line is formed, providing a structural foundation for the realization of subsequent functions such as dual-station parallel operation, precise positioning, and angle adjustment, effectively solving the problems of dispersed processes and low degree of automation in traditional equipment.

[0021] The dual-station cup loading and unloading mechanism 4 includes a vertical plate 41 fixedly installed on the base 1, a cup feeding cylinder 42 fixedly installed on the upper back of the vertical plate 41 with its output end penetrating through the vertical plate 41, a fixed support plate 43 fixedly installed on the upper front of the vertical plate 41, a guide rail 44 fixedly installed below the fixed support plate 43, a slider 45 mounted on the guide rail 44, a movable support plate 46 fixedly installed with the output end of the cup feeding cylinder 42 and with its upper end fixedly installed with the slider 45, an upper cup assembly 47 installed on one side of the movable support plate 46 and cooperating with the cup feeding belt 2, a lower cup assembly 48 installed on the other side of the movable support plate 46 and cooperating with the cup discharging belt 3, and a top cup assembly 49 installed above the fixed support plate 43. The structure of the upper cup assembly 47 is the same as that of the lower cup assembly 48.

[0022] It should be noted that by driving the cup-feeding cylinder 42 to slide the moving plate 46 along the guide rail 44, the upper cup assembly 47 and the lower cup assembly 48 move towards or away from the transfer rotary disk 6 simultaneously, so that the feeding and unloading actions can be performed in parallel, shortening the waiting time between processes and greatly improving production efficiency.

[0023] The cup-loading assembly 47 includes a rotary cylinder 471 fixedly mounted on the side of the movable support plate 46, a rotary angle steel 472 fixedly mounted on the output end of the rotary cylinder 471, a cup-picking and placing telescopic cylinder 473 fixedly mounted on the rotary angle steel 472, and a cup-suction solenoid valve 474 with a suction cup fixedly mounted at the end of the cup-picking and placing telescopic cylinder 473.

[0024] Specifically, the rotating cylinder 471 drives the cup-picking and placing telescopic cylinder 473 to switch between two postures: picking up / placing the cup downwards and picking up / placing the cup towards the printing plate 6. Combined with the vacuum adsorption of the cup suction solenoid valve 474, the cup can be picked up and placed quickly and smoothly. The action is smooth and reliable, avoiding contamination and positional errors caused by manual operation.

[0025] It should be noted that during the operation of the entire dual-station cup-lifting mechanism 4, the rotary cylinders in the upper cup assembly 47 and the lower cup assembly 48 work simultaneously. When both the upper cup assembly 47 and the lower cup assembly 48 are facing downwards, the upper cup assembly 47 extends its cup-suction solenoid valve through the cup-picking and placing telescopic cylinder to pick up the cups that have not yet been transferred from the cup-feeding belt 2, and then retracts. Meanwhile, the lower cup assembly 48 extends its cup-suction solenoid valve through the cup-picking and placing telescopic cylinder to place the picked-up, transferred cups onto the cup-discharge belt 3, and then retracts. When the upper cup assembly 47 and the lower cup assembly 48 are simultaneously facing the transfer rotating disk 6, the output end of the cup feeding cylinder 42 extends, pushing the moving support plate 46 close to the transfer rotating disk 6. At this time, the upper cup assembly 47 extends the suction solenoid valve through the cup picking and placing telescopic cylinder, places the cup body that has not been transferred into the transfer rotating disk 6, and then retracts. Meanwhile, the lower cup assembly 48 extends the suction solenoid valve through the cup picking and placing telescopic cylinder, sucks the transferred cup body tightly from the transfer rotating disk 6, and then retracts and removes it.

[0026] The top cup assembly 49 includes a support plate 491 vertically fixed above the fixed support plate 43, a front top cylinder 492 fixedly installed on the upper end of the support plate 491 and parallel to the fixed support plate 43, and a movable spherical rotating head 493 mounted on the front top cylinder 492.

[0027] Specifically, when the heat transfer mechanism 9 works with the transfer rotating disk 6 and the rotating film holder 8 to perform heat transfer on the cup body, the output end of the front top cylinder 492 pushes out the spherical rotating head 493 and contacts the bottom of the cup. During the heat transfer process, the heat transfer mechanism 9 can hold the bottom of the cup body with the spherical rotating head 493 to prevent the cup body from falling off the transfer rotating disk 6. This effectively prevents the cup body from axially shifting or radially deviating when the transfer rotating disk 6 is rotated and pressed, ensuring that the position of the transferred pattern is accurate and the pattern is clear, achieving a "no deviation" transfer effect. At the same time, the spherical contact surface can reduce wear on the bottom of the cup.

[0028] The support base 5 has a rectangular support 51 inside. A first servo motor 52 for assembling the transfer rotary disk 6 is fixedly installed on the rectangular support 51. Specifically, the transfer rotary disk 6 is fixedly installed on the output end of the first servo motor 52 and is driven to rotate by the first servo motor 52 to achieve precise indexing and high-speed switching of the transfer station. This ensures that each cup mounting mold 61 can accurately reach the upper cup, transfer and lower cup stations in sequence, thereby improving the transfer cycle and positioning accuracy.

[0029] Several cup-body mounting molds 61 are mounted on the edge of the transfer rotary disk 6 via a rotating shaft. These molds are used to assemble the cups. When the heat transfer mechanism 9, in conjunction with the transfer rotary disk 6 and the rotating film holder 8, performs heat transfer on the cups, the cup-body mounting molds 61 can rotate in tandem with the heat transfer mechanism 9, thereby performing heat transfer processing on the outer wall of the cup. Specifically, during heat transfer, the cup-body mounting molds 61 can rotate in tandem with the heat transfer mechanism 9, causing the transfer roller to uniformly roll over the outer wall of the cup in a circumferential direction, ensuring a continuous, complete, and seamless pattern throughout the entire circumference, thus improving the transfer quality.

[0030] A support beam 71 is fixedly installed at the upper front end of the column frame 7, a horizontal plate 72 is fixedly installed at the bottom of the support beam 71, and a second servo motor 73 with a pulley is fixedly installed on one side of the horizontal plate 72. The column frame 7 is also equipped with a rotating plate 74, which is suspended below the horizontal plate 72 by a rotating bushing and has a pulley fixedly installed on the rotating bushing. The column frame 7 is also equipped with a belt 75. One end of the belt 75 is assembled with the pulley of the second servo motor 73, and the other end of the belt 75 is assembled with the pulley on the rotating shaft sleeve of the rotating plate 74. Specifically, the rotating plate 74 can be rotated and adjusted by the second servo motor 73, thereby adjusting the angle of the film belt on the rotating film frame 8 and accurately transferring the transfer plate onto the inclined surface of the cup body.

[0031] It should be further explained that the second servo motor 73 drives the rotating plate 74 to rotate via the belt 75, thereby precisely adjusting the angle of the film belt on the rotating film holder 8, so that the transfer film can fit the cup with a tapered or inclined surface, effectively solving the problem that the traditional fixed angle film holder cannot adapt to the transfer of irregular cups, and expanding the processing range of the equipment.

[0032] The rotating film frame 8 includes a film frame horizontal plate 81, a film tape unwinding assembly 82 fixedly installed on one side of the film frame horizontal plate 81 and on the same side as the cup inlet belt 2, and a film tape winding assembly 83 fixedly installed on the other side of the film frame horizontal plate 81 and on the same side as the cup outlet belt 3. Specifically, the unwinding and winding are integrated on the same film frame horizontal plate 81, resulting in a compact structure that facilitates overall angle adjustment with the rotating plate 74, while ensuring stable tension transmission of the film tape during adjustment.

[0033] The film tape unwinding assembly 82 includes a film tape unwinding vertical plate 821 fixedly installed with the film frame horizontal plate 81, a film tape unwinding roller 822 with gears installed on the upper end of the film tape unwinding vertical plate 821, a film tape unwinding auxiliary plate 823 fixedly installed behind the film tape unwinding vertical plate 821 and with support feet abutting against the film tape unwinding vertical plate 821, an unwinding motor 824 with gears at the output end fixedly installed on the film tape unwinding auxiliary plate 823, a film tape unwinding guide roller group 825 fixedly installed in the middle of the film tape unwinding vertical plate 821 and on the film frame horizontal plate 81, and a first film tape unwinding guide roller group 825 inclinedly installed at the lower end of the film tape unwinding vertical plate 821. The unwinding support rod 826, the film tape unwinding support guide roller group 827 fixedly installed at the end of the first unwinding support rod 826, the second unwinding support rod 828 inclinedly installed at the lower end of the film tape unwinding vertical plate 821 and located below the first unwinding support rod 826, and the film tape output guide roller 829 fixedly installed at the end of the second unwinding support rod 828. Specifically, the gear on the output end of the unwinding motor 824 meshes with the gear on the film tape unwinding roller 822. The inclination angle of the first unwinding support rod 826 is 30°, and the inclination angle of the second unwinding support rod 828 is 45°. The film tape winding assembly 83 includes a film tape winding vertical plate 831 fixedly mounted to the film frame horizontal plate 81, a film tape winding roller 832 with gears mounted on the upper end of the film tape winding vertical plate 831, a film tape winding auxiliary plate 833 fixedly mounted behind the film tape winding vertical plate 831 and with support feet abutting against the film tape winding vertical plate 831, a winding motor 834 with gears at the output end fixedly mounted on the film tape winding auxiliary plate 833, a film tape winding guide roller group 835 fixedly mounted in the middle of the film tape winding vertical plate 831 and on the film frame horizontal plate 81, and a first film tape winding guide roller group 835 inclinedly mounted on the lower end of the film tape winding vertical plate 831. The system includes a take-up support rod 836, a film tape take-up support guide roller group 837 fixedly installed at the end of the first take-up support rod 836, a second take-up support rod 838 inclinedly installed at the lower end of the film tape take-up vertical plate 831 and located below the first take-up support rod 836, and a film tape input guide roller 839 fixedly installed at the end of the second take-up support rod 838. Specifically, the gear on the output end of the take-up motor 834 meshes with the gear on the film tape take-up roller 832. The inclination angle of the first take-up support rod 836 is 30°, and the inclination angle of the second take-up support rod 838 is 45°.

[0034] It should be noted that the significance of the first unwinding support rod 826 and the first winding support rod 836 at 30° and the second unwinding support rod 828 and the second winding support rod 838 at 45° in the rotating film holder 8 is to form a reasonable wrap angle and tension gradient of the film belt on the unfolding and rewinding path through specific tilt angles, effectively preventing the film belt from loosening, deviating or wrinkling, ensuring that the transfer film enters the heat transfer station flat and stably, and ensuring the complete transfer of the transfer pattern.

[0035] The heat transfer mechanism 9 includes a pressing cylinder 91 fixedly mounted on the column frame 7, a long drive column 92 fixedly connected to the pressing cylinder 91, a pressing plate 94 fixedly mounted at the lower end of the long drive column 92, a heat transfer device 95 fixedly mounted below the pressing plate 94 and having a built-in transfer roller, and a third servo motor 96 fixedly mounted on the side of the pressing plate 94 and connected to the transfer roller inside the heat transfer device 95 via a chain.

[0036] Specifically, the lowering cylinder 91 drives the heat transfer unit 95 to rise and fall, and together with the third servo motor 96, drives the transfer roller to rotate via a chain to achieve uniform rolling transfer on the surface of the cup. The pressure and speed can be controlled independently to adapt to the transfer process requirements of cups made of different materials, ensuring the adhesion of the transfer and the clarity of the pattern.

[0037] The specific working principle and steps of this invention are as follows: S1. Initial cup picking and feeding stage: The upper cup assembly 47 and the lower cup assembly 48 in the dual-station upper and lower cup mechanism 4 swing downwards simultaneously under the drive of the rotary cylinder 471. The cup picking and placing telescopic cylinder 473 of the upper cup assembly 47 extends and picks up the untransfer cup from the cup feeding belt 2 through the suction cup of the suction solenoid valve 474 and then retracts. At the same time, the cup picking and placing telescopic cylinder 473 of the lower cup assembly 48 extends and picks up the cup that has been transferred through the suction cup of the suction solenoid valve 474, places it on the cup exit belt 3, and then retracts. S2. Dual-station synchronous cup feeding stage: The upper cup assembly 47 and the lower cup assembly 48 swing to the transfer rotating disk 6 simultaneously under the drive of the rotary cylinder 471. The output end of the cup feeding cylinder 42 extends out and drives the moving plate 46 to slide along the guide rail 44 towards the transfer rotating disk 6, so that the upper cup assembly 47 and the lower cup assembly 48 approach the transfer rotating disk 6 synchronously. S3. Cup loading and unloading stage: The cup loading and unloading telescopic cylinder 473 of the upper cup assembly 47 extends and puts the untransfer cup into the cup mounting mold 61 on the edge of the transfer rotating disk 6. The suction solenoid valve 474 releases the vacuum and retracts. At the same time, the cup loading and unloading telescopic cylinder 473 of the lower cup assembly 48 extends and uses the suction cup of the suction solenoid valve 474 to suck and take out the cup that has been transferred from the cup mounting mold 61. After retraction, it is placed on the cup delivery belt 3 for the next cycle. The cup delivery cylinder 42 retracts and drives the moving tray 46 to reset. S4. Transfer Rotary Table Indexing and Top Cup Positioning Stage: The first servo motor drives the transfer rotary table 6 to rotate one station, rotating the cup body mounting mold 61 with the untransferred cup body to the heat transfer station. The front top cylinder 492 of the top cup assembly 49 extends, driving the spherical rotating head 493 to press against the bottom of the cup, so that the cup body maintains axial positioning during subsequent rotation. S5. Film belt angle adjustment stage for tilted cup surface: According to the tilt angle of the cup, the second servo motor 73 drives the rotating plate 74 to rotate through the belt 75, which drives the rotating film frame 8 to rotate to the corresponding angle, so that the transfer film output by the film belt unwinding assembly 82 covers the tilted surface of the cup with the best fitting angle. S6. Heat transfer stage: The pressing cylinder 91 of the heat transfer mechanism 9 drives the lower platen 94 to descend through the long drive column 92, so that the transfer roller in the heat transfer unit 95 presses the transfer film on the outer wall of the cup; the third servo motor 96 drives the transfer roller inside the heat transfer unit 95 to rotate through the chain, and at the same time the cup mounting mold 61 rotates in coordination, and the transfer roller continuously rolls and transfers the pattern on the film strip to the outer wall of the cup; during the transfer process, the film strip unwinding motor 824 and the rewinding motor 834 work synchronously, so that the untransferable film strip is continuously input and the used film strip is synchronously rewound. S7. Cyclic Operation: After the transfer is completed, the pressing cylinder 91 drives the heat transfer device 95 to rise and reset, and the front lifting cylinder 492 drives the spherical rotating head 493 to retract; the first servo motor drives the transfer rotating disk 6 to continue rotating one station, and sends the cup that has been transferred to the next cup station; then repeat steps one to six to achieve continuous cyclic production.

[0038] In summary, the core features of this working principle are the parallel collaboration of dual workstations and precise control throughout the entire process: the upper cup assembly 47 and the lower cup assembly 48 move forward and backward synchronously under the drive of the cup feeding cylinder 42, realizing the parallel execution of cup picking, placing, and loading / unloading actions, enabling the transfer rotary disk 6 to rotate continuously in increments, significantly shortening the production cycle; the spherical rotating head 493 of the top cup assembly 49 actively presses against the bottom of the cup before transfer, forming a double axial positioning with the cup body mounting mold 61, effectively preventing the cup body from shifting or falling off when subjected to rolling force, ensuring the accuracy of pattern transfer; the second servo motor 73 can independently adjust the angle of the rotating film frame 8, so that the film tape fits the inclined surface of the cup body, expanding the processing capability of irregularly shaped cups; during the heat transfer process, the pressing, rotation, and film tape winding and unwinding are coordinated and linked, and the parameters are independently adjustable. The entire cycle is automatically completed by each execution element according to a strict timing sequence, with clear separation of processes and no interference between them, combining the comprehensive advantages of high efficiency, high precision, strong adaptability, and easy maintenance.
