Description

Technical Field

[0001] The invention belongs to the technical field of printing equipment, and in particular relates to a multi-color glass bottle printing device. Background Art

[0002] Glass bottles with designs or logos printed on them are called printed glass bottles. Printed glass bottles elevate packaging to a higher level. Initially, single-color printing evolved into three-color printing. Today, six- and eight-color printing techniques are now widely used. This has led to the emergence of a new beverage packaging favorite: the multi-color printed glass bottle.

[0003] Multi-color printed glass bottles are made by softening a glass glaze into an ink-like liquid at a certain temperature. This is then printed onto the bottle surface using a screen printer (also known as a printing machine). The printed pattern is then baked at temperatures exceeding 600°C, blending the glaze and glass into a single piece. The pattern is acid- and alkali-resistant, non-fading, and wash-resistant, and is available in up to eight color combinations for your convenience.

[0004] Due to the complexity and difficulty of the multi-color printing process, it is difficult for the printing device in the existing technology to perform multi-color printing on one device at the same time, which is prone to printing defects and cannot guarantee printing quality, affecting the overall efficiency and leading to increased printing costs.

[0005] Therefore, the existing technology needs to be improved and developed. Summary of the Invention

[0006] The purpose of the embodiment of the present application is to provide a multi-color glass bottle printing device that can perform multi-color printing on the same device at the same time. The pattern printed on the surface of the glass bottle is of high quality, the printing efficiency is improved, and the printing cost is reduced.

[0007] To solve the above technical problems, the multi-color glass bottle printing device provided in the embodiment of the present application includes a printing device body, wherein the printing device body is provided with a workbench, and the workbench is provided with a plurality of workstations at equal intervals along its circumference, and each workstation is provided with:

[0008] Screen fixing device, installed on the workbench, used to fix the screen;

[0036] Figure 1 A three-dimensional diagram of a multi-color glass bottle printing device according to the present invention is shown. Figure 2 The figure is a three-dimensional diagram of the hidden ink barrel and top beam of the multi-color glass bottle printing device of the present invention. The multi-color glass bottle printing device of the present invention includes a printing device body 1, the bottom of the printing device body 1 is in the shape of an octagonal prism, eight columns 13 are provided on the outer edge of the top of the printing device, and a driving shaft 16 is provided in the middle of the printing device. The columns 13 and the driving shaft 16 are installed with hinges at the same height. The hinge at the end of the column 13 is hinged to one end of the movable beam 15, and the hinge at the end of the driving shaft 16 is hinged to the other end of the movable beam 15. The driving shaft 16 can reciprocate in a straight line along the vertical direction, so that the movable beam 15 swings around the axis with the hinge at the end of the column 13 as the fulcrum. Each movable beam 15 is fixed with a first supporting device 6 and a second supporting device 7. The first supporting device 6 is fixed to the angle-adjustable scraper 5, and the second supporting device 7 is connected to one end of the screen fixing device 3. A top beam 14 is provided on the top of the printing device body 1 , and eight ink barrels 2 for providing ink for printing are hung above the top beam 14 , and each ink barrel 2 is filled with ink of a different color.

[0037] A workbench 17 is located in the middle of the printing device body 1, and a rotatable rotary table 18 is mounted on the workbench 17. Multiple workstations are arranged at equal intervals along the circumference of the workbench 17. In this embodiment, there are eight workstations, six of which are printing stations capable of printing patterns in six different colors. The other two are feeding and discharging stations. A feeding port 11 and a discharging port 12 are provided on the side of the printing device body 1, respectively, for placing unprinted glass bottles and removing printed glass bottles. Each workstation is equipped with a screen fixing device 3, a bottle bottom fixing device 10, a tumbling device 9, and a clamping device 4.

[0038] The left end of the screen fixture 3 is mounted on the workbench 17, while the right end is clamped by the lower end of the second support device 7. The second support device 7 is equipped with two rollers that clamp the sides of the screen fixture 3. The upper end of the second support device 7 is a frame that matches the size of the movable beam 15 and is fastened to the movable beam 15 via adjustment screws. As the movable beam 15 swings around the fulcrum, it drives the second support device 7 and the screen fixture 3 to swing. The screen fixture 3 is designed with an internal power source, enabling it to perform linear reciprocating motion in the horizontal direction when the movable beam 15 reaches its lowest point.

[0039] A tumbling device 9 is fixed to the upper surface of the workbench 17. A bottle bottom fixture 10 is fixed to the left end of the tumbling device 9. The tumbling device 9 is capable of rotating the bottle bottom fixture 10 and the glass bottle secured thereto. Due to various considerations, such as cost and design, the bottoms of most soda and beer bottles currently on the market are cylindrical. Therefore, the bottle bottom fixture 10 can be a concave cross-section with an inner diameter slightly larger than the diameter of the glass bottle's bottom, allowing manual or robotic insertion into the cavity of the bottle bottom fixture 10. The tumbling device 9 can be any device capable of rotating the bottle bottom fixture 10, such as various types of rotary motors. In this embodiment, to achieve simultaneous printing of the glass bottles at each station and simultaneous rotation and movement to the next station after printing, the tumbling device 9 utilizes a mechanical transmission to improve the reliability of the printing apparatus. The tumbling device 9 includes a first bevel gear 19, eight second bevel gears 91, eight cylindrical gears 94 and eight sets of rotating pairs. The rotating pairs adopt a combination of a commonly used hinge seat 93 and a rotating shaft. One end of the horizontally arranged rotating shaft is fixed to the second bevel gear 91 through a coupling 92, and the other end of the rotating shaft is connected to the cylindrical gear 94 and the bottle bottom fixing device 10. The cylindrical gear 94 is close to the rotating shaft. Figure 4 and Figure 5As shown, during the working process, the first bevel gear 19 is retracted by the output rod of the servo electric cylinder at its bottom to a position where the gear teeth are disengaged from the second bevel gear 91, and the driving shaft 16 follows the second bevel gear 91 fixed thereto to descend, driving the first supporting device 6 and the angle-adjustable scraper 5 to move downward to contact the screen of the screen fixing device 3, and the screen fixing device 3 moves linearly from one end to the other end, and the screen fixing device 3 drives the cylindrical gear 94 and the bottle bottom fixing device 10 to rotate. At this time, the ink penetrates into a certain line on the surface of the glass bottle under the pressure of the scraper, and then the screen is The plate moves accordingly, and the glass bottle rotates one circle to form a pattern until the printing of a single color is completed; after the printing of a single color is completed, the first bevel gear 19 is pushed by the output rod of the servo electric cylinder at its bottom to a position where the gear teeth engage with the second bevel gear 91, and the rotation of the rotary table 18 drives the hinge seat 93 to rotate. Since the first bevel gear 19 is non-rotatable, the rotating shaft will rotate around the hinge seat 93. At this time, the glass bottle rotates in the opposite direction. When the rotary table 18 rotates to the next station, the glass bottle returns to its original position to facilitate the printing of the next color.

[0040] In this embodiment, the clamping device 4 comprises a pneumatic cylinder and a bottle mouth support device, which is equipped with two freely rotatable rollers. During the printing process, the pneumatic cylinder pushes the bottle mouth support device to clamp the bottle mouth, causing the two freely rotatable rollers to be tangential to the bottle mouth. The rolling device 9 drives the bottle bottom fixture 10 to rotate, and the glass bottle rotates synchronously with the bottle bottom fixture 10. The bottle mouth support device applies a certain horizontal preload to the glass bottle to prevent shaking when the scraper contacts the glass bottle surface, ensuring stability during the printing process and avoiding printing defects.

[0041] In order to further improve the stability of the glass bottle during the printing process, it is also necessary to provide support at the bottle body of the glass bottle. The bottle body support device 8 is installed on the side of the rotating table 18. The rotating table 18 will rotate with the rotating table 18 during the rotation process. There are many ways to support the bottle body. In this embodiment, the bottle body support device 8 adopts a Y-shaped bracket. The Y-shaped bracket can not only play an accurate positioning role, but also facilitates the installation and disassembly of the glass bottle.

[0042] Controlling the ink's temperature is crucial. If the temperature is too low and the humidity is high, the ink won't flow and will easily form clumps. If the temperature is too high and the humidity is low, the volatility is high, and the ink becomes more viscous, easily sticking to the screen and clogging the mesh, resulting in a series of defects such as screen clogging, blistering, and blackening. In this embodiment, an ink barrel 2 is mounted on the top beam 14. A heating device and a temperature sensor are installed within the barrel 2. These are connected to a controller via wires. The controller sets the ink temperature between 100 and 120 degrees Celsius. The temperature sensor provides real-time feedback on the current temperature. When the current temperature falls below the preset range, the controller controls the heating device to heat the ink; if it exceeds, heating stops, ensuring that the ink temperature remains within the preset range. A conduit 21 is installed at the bottom of the ink barrel 2, extending into the screen. This conduit controls the ink feed rate via a solenoid valve or other valve. In this embodiment, the controller sets a 150-second interval for each feed, and the duration of a single feed, i.e., the valve opening time, is 0.5 seconds. Once the valve is opened, the ink drips down the conduit 21 onto the screen by gravity, eliminating the need for an additional power source and reducing the complexity of the device. The ink supply and heating are both automated, avoiding the temperature inaccuracies associated with traditional manual ink supply.
