Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a tapered cup printing swing structure that can prevent deviation. Background Technology

[0002] In the production of commercial cups, printing on the outer surface of the cup often employs a rotatable drum to position and rotate the cup, ensuring complete coverage of the printed material on the cup wall. This method is well-suited for printing on straight-walled cups. However, for cups with a tapered shape, where the outer surface is inclined, it is difficult to maintain a stable contact angle, pressure, and relative speed between the printing head and the cup wall during rotation. This can easily lead to stretching and deformation of the printed material, blurred edges, or misregistration, resulting in the inability to form high-quality patterns and severely impacting production quality.

[0003] For printing on the outer surface of tapered cups, the industry has explored various solutions, including linear printing. However, linear printing has significant drawbacks: the movement trajectory of the print head or substrate is linear, making it impossible to dynamically match the tilt angle of the cup wall at different heights. This results in large tension fluctuations and uneven contact between the print head and the cup surface during printing, leading to issues ranging from insufficient pattern clarity to problems like layering and ghosting, completely failing to meet the high-quality printing requirements of tapered cups. In contrast, oscillating printing, with its strong adaptability to the tapered shape, has become the preferred solution for printing on the outer surface of tapered cups. This method drives the substrate (tapered cup) to oscillate in an arc, adjusting the arc sweep range of the movement trajectory in real time according to the size of the taper—that is, dynamically adapting to the tilt angle of the cup wall to ensure stable tension throughout the printing process, while maintaining uniform contact between the print head and the cup surface. This effectively avoids the poor adaptability problem caused by the "fixed trajectory" of linear printing, fundamentally improving the integrity and clarity of the printed pattern on tapered cups during heat transfer processing.

[0004] However, existing oscillating printing solutions still have areas for optimization: on the one hand, the larger the taper, the larger the required oscillation angle, and the larger the corresponding oscillation structure size, resulting in a significant increase in the equipment footprint, which is detrimental to the spatial layout of the production workshop; on the other hand, because paper tapered cups are relatively soft and thin-walled, gaps easily form between their inner walls and the supporting frustum during positioning and rotation, causing the tapered cup to shift on the supporting frustum, ultimately compromising printing alignment accuracy and affecting overall printing quality. Therefore, we propose an anti-shifting tapered cup printing oscillation structure. Utility Model Content

[0005] The purpose of this invention is to provide a tapered cup printing swing structure that can prevent deviation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a taper cup printing swing structure with anti-deviation capability, comprising a worktable and a column fixedly installed on the top of the worktable, an upper cylinder fixedly installed on the side of the top of the column, a pressure plate fixedly installed on the output end of the upper cylinder, and a fan-shaped swing module disposed on the upper surface of the worktable. The fan-shaped swing module includes a servo motor fixedly installed on the inner wall of the worktable, a rotating rod fixedly installed on the output end of the servo motor, an upper support plate fixedly installed on the top end of the rotating rod, a table panel movably installed on the surface of the upper support plate, a second mounting seat fixedly installed on the upper surface of the table panel, an I-shaped slide fixedly installed on the upper surface of the worktable, a lower support plate slidably installed on the top surface of the I-shaped slide, a sliding support plate slidably installed on the upper surface of the lower support plate, a support platform rotatably installed on the side wall of the second mounting seat, a first mounting seat fixedly installed on the upper surface of the table panel, a lower cylinder fixedly installed on the side wall of the first mounting seat, and a pressing block rotatably installed on the output end of the lower cylinder.

[0007] Preferably, the top of the fan-shaped swing module is provided with a filling module, the filling module including an air inlet chamber, the air inlet chamber being opened in the inner wall of the support platform, a spring being fixedly installed in the inner wall of the support platform, a silicone plug being fixedly connected to the end of the spring, an air blowing chamber penetrating the air inlet chamber being opened in the inner wall of the support platform, a small air pump being fixedly installed in the side wall of the second mounting base, an air inlet pipe being fixedly connected between the output end of the small air pump and the air inlet chamber, a sealing ring being rotatably installed in the side wall of the second mounting base, an annular groove being opened in the side wall of the sealing ring, and a number of protruding ridges being arranged in a circumferential array on the inner surface of the annular groove.

[0008] Preferably, the lower surfaces of the upper support plate, the sliding support plate, and the lower support plate are all provided with T-shaped sliders, and the upper surfaces of the sliding support plate, the lower support plate, and the I-shaped slide are all provided with T-shaped grooves that are adapted to the size of the T-shaped sliders, and the T-shaped grooves of the sliding support plate and the lower support plate are perpendicular to the T-shaped grooves opened on the upper surface of the I-shaped slide.

[0009] Preferably, a sealing ring is provided on the outer surface of the end of the air intake pipe near the support platform, and the air intake pipe is rotatably connected to the inner wall of the air intake chamber.

[0010] Preferably, the inner wall of the support platform has a circular hole with a diameter larger than the outer diameter of the spring. The two ends of the spring are fixedly connected to the inner wall of the end of the circular hole and the side wall of the silicone plug, respectively. The air intake cavity includes a wide diameter section and a narrow diameter section. The diameter of the silicone plug is larger than the narrow diameter section of the air intake cavity and smaller than the wide diameter section.

[0011] Preferably, the support platform is frustum-shaped, and the inner diameter of the closed ring is larger than the diameter of the bottom edge of the support platform, and the protruding ridge is set as a parallelogram.

[0012] Preferably, the side of the protruding ridge is inclined relative to the radial direction of the closed ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This anti-deviation tapered cup printing swing structure, through the setting of the fan-shaped swing module, enables the tapered cup to swing in a fan shape on the worktable while contacting the pressure plate and generating rotation. This reduces the footprint of the entire equipment while ensuring the quality of the heat transfer process. When the tapered cup is placed on the support platform, the closing ring seals the opening of the tapered cup. At this time, a small air pump is started, and air enters the gap between the support platform and the tapered cup through the air blowing chamber to fill the internal gap of the tapered cup, preventing local depressions that would affect the fan-shaped printing effect of the tapered cup. This prevents the printed material on the tapered cup from shifting and affecting the printing quality. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-6 The diagram shows a tapered cup printing swing structure that can prevent deviation, including a worktable 1, a column 2 fixedly installed on the top of the worktable 1, an upper cylinder 3 fixedly installed on the top side of the column 2, a pressure plate 4 fixedly installed on the output end of the upper cylinder 3, and a fan-shaped swing module set on the upper surface of the worktable 1.

[0023] The column 2 and the upper surface of the worktable 1 are kept perpendicular to each other. Meanwhile, the side wall of the column 2 is provided with a mounting plate for the upper cylinder 3 to be installed, and the upper surface of the pressure plate 4 is provided with a guide rod to ensure that the pressure plate 4 can move downward smoothly under the drive of the upper cylinder 3, thereby pushing the heat transfer film to the outer surface of the tapered cup. Then, the pattern is printed from the transfer film onto the tapered cup by external heating, thus completing the heat transfer process of the tapered cup.

[0024] The top of the fan-shaped swing module is equipped with a filling module, which includes a second mounting base 15. A support platform 16 is rotatably mounted on the side wall of the second mounting base 15. An air inlet chamber 17 is opened on the inner wall of the support platform 16. A spring 19 is fixedly mounted on the inner wall of the support platform 16. A silicone plug 18 is fixedly connected to the end of the spring 19. An air blowing chamber 20 that passes through the air inlet chamber 17 is opened on the inner wall of the support platform 16. A small air pump 21 is fixedly mounted on the side wall of the second mounting base 15. An air inlet pipe 22 is fixedly connected between the output end of the small air pump 21 and the air inlet chamber 17. A sealing ring 23 is rotatably mounted on the side wall of the second mounting base 15. An annular groove 24 is opened on the side wall of the sealing ring 23. Several protruding ridges 25 are arranged in a circumferential array on the inner surface of the annular groove 24.

[0025] Please see Figures 4-6The support platform 16 provides a place for the tapered cup, facilitating its positioning. Simultaneously, the support platform 16 and the closing ring 23 are coaxially aligned, ensuring that the support platform 16, the closing ring 23, and the tapered cup fitted onto the outside of the support platform 16 maintain the same speed of movement. This improves the accuracy and relative stability of the tapered cup during heat transfer printing. Furthermore, the air blowing chamber 20 is inclined towards the mounting base 15 on the side furthest from the center of the support platform 16. This ensures that the airflow from the air inlet chamber 17 and the air blowing chamber 20 into the gap between the support platform 16 and the tapered cup does not affect the stable installation of the tapered cup. This guarantees the filling effect during installation and prevents the tapered cup from slipping backward, affecting the fan-shaped printing effect. Additionally, multiple sets of air blowing chambers 20 are arranged in a linear array on the inner surface of the support platform 16, resulting in more uniform and stable gas filling in the gap between the support platform 16 and the tapered cup, preventing localized excessively rapid inflation that could cause deformation of the tapered cup.

[0026] The fan-shaped swing module includes a servo motor 6 fixedly installed on the inner wall of the worktable 1. A rotating rod 7 is fixedly installed at the output end of the servo motor 6. An upper support plate 10 is fixedly installed at the top of the rotating rod 7. A table panel 11 is movably installed on the surface of the upper support plate 10. The upper surface of the table panel 11 is fixedly connected to the mounting base 15. An I-shaped slide 5 is fixedly installed on the upper surface of the worktable 1. A lower support plate 8 is slidably installed on the top surface of the I-shaped slide 5. A sliding support plate 9 is slidably installed on the upper surface of the lower support plate 8. The upper surface of the sliding support plate 9 is slidably engaged with the upper support plate 10.

[0027] Please see Figures 2-3 The back of the worktable 1 is provided with a heat dissipation cavity to facilitate the installation of the servo motor 6. At the same time, the lower support plate 8 slides horizontally left and right on the upper surface of the I-shaped slide table 5, while the sliding support plate 9 and the upper support plate 10 move horizontally back and forth on the upper surfaces of the lower support plate 8 and the sliding support plate 9, respectively. When the servo motor 6 is started, in conjunction with the rotation of the rotating rod 7, the filling module set on the upper surface of the table panel 11 is finally moved in a fan shape to realize the fan-shaped printing processing of the tapered cup. Specifically, one end of the upper support plate 10 is hinged to the table panel 11, and a screw is fixedly installed on the other end of the upper support plate 10. At the same time, the inner wall of the table panel 11 is provided with a straight groove that matches the outer diameter of the screw. Two sets of threaded blocks are set on the upper and lower sides of the straight groove, thereby realizing the angle adjustment and stable installation of the table panel 11 on the upper support plate 10.

[0028] A mounting base 12 is fixedly installed on the upper surface of the table panel 11. A lower cylinder 13 is fixedly installed on the side wall of the mounting base 12. A clamping block 14 is rotatably installed at the output end of the lower cylinder 13.

[0029] The lower cylinder 13, the pressing block 14, and the support platform 16 are aligned on the same straight line. Therefore, during tapered cup installation, the tapered cup is first aligned with the support platform 16. Then, the lower cylinder 13 is activated, pushing the pressing block 14 to contact the bottom of the tapered cup. As the output end of the lower cylinder 13 continues to extend, the pressing block 14 finally presses the tapered cup onto the support platform 16. Due to the rotatability of the pressing block 14, it does not affect the free rotation of the tapered cup on the support platform 16. During the printing process, due to the adhesion between the transfer film and the tapered cup, driven by the fan-shaped swing module, the tapered cup rotates together with the support platform 16 due to the pressing effect of the transfer film.

[0030] The lower surfaces of the upper support plate 10, the sliding support plate 9, and the lower support plate 8 are all provided with T-shaped sliders, and the upper surfaces of the sliding support plate 9, the lower support plate 8, and the I-shaped slide table 5 are all provided with T-shaped grooves that are adapted to the size of the T-shaped sliders. Furthermore, the T-shaped grooves of the sliding support plate 9 and the lower support plate 8 are perpendicular to the T-shaped grooves opened on the upper surface of the I-shaped slide table 5.

[0031] Please see Figure 3 By setting the T-shaped slider, the lower support plate 8 and the I-shaped slide table 5 can only move left and right in the horizontal direction. At the same time, the sliding support plate 9 and the lower support plate 8, as well as the upper support plate 10 and the sliding support plate 9, can only move back and forth in the horizontal direction. With the servo motor 6 driving the rotating rod 7, the fan-shaped movement of the filling module on the upper support plate 10 is realized, which facilitates the fan-shaped printing work of the tapered cup.

[0032] A sealing ring is provided on the outer surface of the intake pipe 22 near the support platform 16, and the intake pipe 22 is rotatably connected to the inner wall of the intake chamber 17.

[0033] The sealing ring allows the air output from the small air pump 21 to be input into the air intake chamber 17, while preventing air leakage at the end of the air intake pipe 22. Furthermore, the air intake pipe 22 does not affect the free rotation of the support platform 16.

[0034] The inner wall of the support platform 16 has a circular hole with a diameter larger than the outer diameter of the spring 19. The two ends of the spring 19 are fixedly connected to the inner wall of the end of the circular hole and the side wall of the silicone plug 18, respectively. The air intake chamber 17 includes a wide diameter section and a narrow diameter section. The diameter of the silicone plug 18 is larger than the narrow diameter section of the air intake chamber 17 and smaller than the wide diameter section.

[0035] Please see Figure 5The circular hole provides installation space for the spring 19. Under the elastic force of the spring 19, the silicone plug 18 initially seals the narrow section of the air inlet chamber 17. When the small air pump 21 starts and introduces air into the air inlet chamber 17, as the air pressure in the narrow section increases, it eventually overcomes the elastic force of the spring 19 and exerts a thrust on the silicone plug 18, causing the spring 19 to stretch and expose the gap between the silicone plug 18 and the wide section. This allows air to be blown through the air inlet chamber 17 and the blowing chamber 20 to the gap between the support platform 16 and the tapered cup, filling the internal gap of the tapered cup and preventing local depressions that could affect the fan-shaped printing effect of the tapered cup.

[0036] The support platform 16 is shaped like a frustum, and the inner diameter of the closed ring 23 is larger than the bottom diameter of the support platform 16. The protruding rib 25 is set as a parallelogram.

[0037] Please see Figure 6 The side of the protruding rib 25 is inclined relative to the radial direction of the closing ring 23, so that when the tapered cup is sleeved on the outer surface of the support platform 16, the end of the tapered cup extends into the annular groove 24. The side of the protruding rib 25 contacts the top of the tapered cup, and the annular groove 24 seals the opening of the tapered cup, preventing the tapered cup from falling off the support platform 16 and affecting the heat transfer processing effect of the tapered cup.

[0038] Working principle: First, the tapered cup is aligned with the support platform 16. Then, the lower cylinder 13 is activated, pushing the pressing block 14 to contact the bottom of the tapered cup. As the output end of the lower cylinder 13 continues to extend, the pressing block 14 finally presses the tapered cup onto the support platform 16. Then, the small air pump 21 is activated, and air is introduced into the air inlet chamber 17 through the air inlet pipe 22. Finally, the air enters the gap between the support platform 16 and the tapered cup through the air blowing chamber 20 to fill the internal gap of the tapered cup, ensuring that the air pressure in the gap of the tapered cup is maintained at 0.02-0.05MPa. This prevents local depressions and also prevents excessive expansion, which could affect the fan shape of the tapered cup. After achieving the desired printing effect, the upper cylinder 3 is activated, driving the pressure plate 4 to move downwards and pushing the transfer film towards the outer surface of the tapered cup until the transfer film adheres to the outer surface of the tapered cup. Finally, the servo motor 6 is activated, cooperating with the rotation of the rotating rod 7, so that the lower support plate 8 slides left and right on the I-beam slide table 5. At the same time, the sliding support plate 9 and the lower support plate 8, as well as the upper support plate 10 and the sliding support plate 9, can rotate relative to each other in the horizontal direction. With the servo motor 6 driving the rotating rod 7, the filling module on the upper support plate 10 achieves a fan-shaped movement. Simultaneously, the external heating equipment is activated to heat the transfer film, printing the pattern on the transfer film onto the tapered cup, resulting in a printed tapered cup.
