Description

Technical Field

[0001] This application relates to the field of glass screen printing technology, and in particular to a high-efficiency glass screen printing machine capable of simultaneous screen printing of single items in two zones. Background Technology

[0002] The decoration and functionalization of glass surfaces have become core elements in enhancing product added value. Today, glass screen printing technology has become one of the core processes in the deep processing of glass, and its application scenarios continue to expand. In the automotive industry, it is used to print sun visors, dashboard markings, and scratch-resistant coatings; in the construction industry, it is used to print decorative patterns, privacy stripes, and heat-insulating coatings on glass curtain walls; and in the home furnishing industry, it is used to print frosted patterns on bathroom glass and oil-resistant coatings on kitchen glass. With continuous innovation in new materials (such as environmentally friendly inks and flexible glass) and new processes (such as 3D screen printing and digital screen printing combined), glass screen printing technology is developing towards greater environmental friendliness, efficiency, precision, and functionality, providing continuous impetus for the functional upgrading and aesthetic enhancement of glass products.

[0003] Currently, some production scenarios still rely on manual handling of glass to complete the screen printing job. This is not only labor-intensive and time-consuming, but the instability of manual operation can also affect the production rhythm, resulting in low overall production efficiency and maintenance efficiency. Even with the adoption of existing assembly line equipment for automated production, since both ends of the glass usually need to be screen printed, the conventional process requires printing one end first and then conveying the glass back and forth twice to complete the printing of the other end. This repetitive process increases the amount of wasted time and makes it difficult to improve production efficiency. Another solution for screen printing on both ends is to make the screen larger to completely cover the entire glass surface. However, for large glass products, it is necessary to use an extra-large squeegee, which not only increases the equipment manufacturing cost, but also leads to excessive consumption of ink and other materials, resulting in serious waste. Utility Model Content

[0004] This device provides a high-efficiency glass screen printing machine capable of simultaneous dual-zone screen printing on a single item. The specific implementation method is as follows: A high-efficiency glass screen printing machine capable of simultaneous dual-zone screen printing on a single item, comprising: Lifting conveyor belt for longitudinally transporting glass sheets; An upper frame is located above the lifting conveyor belt. A translation seat is slidably mounted on the upper frame, and a pair of screen printing heads are arranged side by side along the longitudinal direction on the translation seat. A screen printing stencil is located at the bottom of the upper frame, and the upper frame and the screen printing stencil are connected by a lifting assembly. The lifting assembly drives the screen printing stencil to press down on the glass plate, and the translation seat drives a pair of screen printing heads to simultaneously screen print horizontally on both ends of the glass plate.

[0005] Preferably, the upper frame has a horizontal U-shaped overall structure, and the translation seat is horizontally slidably disposed on the inner side of the U-shape of the upper frame; the inner side of the upper frame is provided with a guide rail and a first toothed plate in parallel along the length direction, the end of the translation seat is slidably connected to the guide rail, and the translation seat is also meshed with the first toothed plate through a motor gear.

[0006] Based on the above technical solutions, a lifting conveyor belt design is adopted to achieve stable longitudinal transport of the glass plate. The translational seat is equipped with a pair of screen printing heads to complete the dual-zone synchronous screen printing on both ends of the glass plate. There is no need to wait for the operation on one side to be completed. The printing action on both ends starts simultaneously. While ensuring uniform ink adhesion and precise pattern alignment, it completely breaks through the efficiency bottleneck of traditional single-zone printing and significantly improves the production cycle. The installation position of the screen printing head on the translational seat can be flexibly adjusted and can be quickly adapted to the size requirements of glass plates of different specifications. This provides the production line with stronger flexibility and adaptability, helping enterprises to balance efficiency and cost advantages in mass production.

[0007] Preferably, the screen printing head includes a mounting base bolted to a translation seat, on which a pair of telescopic cylinders are arranged side by side, and the air arm ends of the telescopic cylinders are respectively connected downward to a screen printing squeegee and a glue removal squeegee.

[0008] Preferably, the outer side of the upper frame is provided with a downwardly guiding mounting groove, a lifting component is installed in the mounting groove, and a lifting seat for laying the screen printing plate is also vertically slidably provided in the mounting groove, and the lifting component is connected to the lifting seat.

[0009] Preferably, the lifting assembly includes a motor and a drive shaft. The output end of the motor is connected to the drive shaft via a gear set, and the two ends of the drive shaft are respectively provided with drive teeth. The lifting seat includes a square frame, and a sliding plate is vertically provided at the end of the square frame. The sliding plate is slidably connected to the mounting groove, and the sliding plate meshes with the drive teeth through a second rack.

[0010] Based on the above technical solutions, the structure of the screen printing head and the screen printing head screen printing on the glass plate through the screen printing screen are conventional technical means in this field. The air circuits of the two telescopic cylinders can be used in combination with the help of a switching valve, that is, the screen printing squeegee and the adhesive removal squeegee are switched in steps, and when one falls, the other rises.

[0011] Preferably, it also includes a mounting plate, which is slidably connected to the square frame in the horizontal direction. Both the mounting plate and the square frame are designed to be vertically guided. A screen printing plate is installed on the inner side of the mounting plate through a positioning clip, and a handle is provided on the outer side of the mounting plate.

[0012] Preferably, the translation seat is provided with a limiting guide groove in the longitudinal direction, and the limiting guide groove and the mounting seat are slidably connected along the length direction, and the two are positioned by bolts.

[0013] Based on the above technical solutions, a sliding connection structure between the lifting seat and the mounting plate is adopted. The screen printing plate can be replaced without complicated disassembly by pulling it out laterally. The plate can be quickly picked up and positioned by simply pushing and pulling, which greatly shortens the plate replacement time. In addition, conventional card locking or bolt locking can be equipped at the sliding point of the two to limit the pulling degree of the mounting plate and lock it after it returns to its original position.

[0015] In summary, this application includes the following beneficial technical effects: 1. This utility model uses a lifting conveyor belt to longitudinally transport glass plates, and at the same time uses a translational seat to realize a pair of screen printing heads to perform dual-zone synchronous screen printing on both ends of the glass plate. Without wasting materials, it greatly improves screen printing efficiency. By changing the installation position of the screen printing head on the translational seat, it can also be adapted to glass plates of different sizes. 2. This utility model has a simple structure. By sliding the lifting seat and the mounting plate, the mounting plate can be pulled out laterally, thereby enabling the quick replacement of the screen printing plate and further improving the efficiency of screen printing plate disassembly and maintenance. 3. This utility model sets up a screen printing plate that is wider than the screen printing head, and different patterns are arranged side by side on the screen printing plate. According to the corresponding position relationship between the screen printing head and the pattern, the screen printing pattern can be adjusted. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0021] This application discloses a high-efficiency glass screen printing machine capable of simultaneous screen printing of a single item in two zones.

[0022] Example 1 Reference Figures 1 to 5This embodiment discloses a high-efficiency glass screen printing machine capable of simultaneous screen printing on a single item in two zones. It includes a lifting conveyor belt 9 for longitudinally conveying a glass plate 10, a lower frame 8 for supporting the glass plate 10, an upper frame 1 located above the lifting conveyor belt 9, and a screen printing screen 3 located at the bottom of the upper frame 1. A translation seat 5 is slidably provided on the upper frame 1, and a pair of screen printing heads 2 are arranged in parallel along the longitudinal direction on the translation seat 5. In this structure, the glass plate 10 is conveyed longitudinally, and the pair of screen printing heads 2 act laterally on both ends of the glass plate 10 simultaneously, thereby realizing the simultaneous screen printing operation on both ends of the glass plate 10.

[0023] The upper frame 1 is connected to the screen printing stencil 3 via a lifting assembly 4. The lifting assembly 4 drives the screen printing stencil 3 to press down on the glass plate 10. The upper frame 1 has a horizontal U-shaped overall structure. The translation seat 5 is horizontally slidably disposed on the inner side of the U-shape of the upper frame 1. The inner side of the upper frame 1 is provided with a guide rail 101 and a first toothed plate 102 arranged in parallel along the length direction. The end of the translation seat 5 is slidably connected to the guide rail 101, and the translation seat 5 is also meshed with the first toothed plate 102 through a motor gear.

[0024] The lower frame 8 includes a base 802 and several plates 801 arranged horizontally on the top of the base 802. There is a gap between adjacent plates 801. The lifting part of the lifting conveyor belt 9 is built into the base 802, and the belt drive part of the lifting conveyor belt 9 is vertically aligned with the gap. In this structure, the lifting conveyor belt 9 consists of a conveyor belt and a lifting platform. Each parallel conveyor belt is connected to a power source, and each parallel conveyor belt is connected to the output end of the lifting platform. The lifting platform controls the vertical movement of the conveyor belt through the gap to lift and transport the glass plate 10. To prevent the glass plate 10 from shifting during transportation and screen printing, limit rods can be set on both sides to prevent the glass plate 10 from shifting.

[0025] The screen printing head 2 includes a mounting base 201 bolted to the translation seat 5. A pair of telescopic cylinders 202 are arranged side by side on the mounting base 201. The air arm end of the telescopic cylinders 202 is respectively connected to a screen printing squeegee 203 and a glue removal squeegee 204. In this structure, the pair of telescopic cylinders 202 form a logic circuit using a reversing valve, a check valve, and a shuttle valve. The pressure signal of the hydraulic oil realizes the "action interlock" of the two cylinders. When one telescopic cylinder 202 receives oil and extends and rises, the return oil path of the other telescopic cylinder 202 is opened, and its inlet oil path is cut off, forcibly retracting and falling down.

[0026] The outer side of the upper frame 1 is provided with a downwardly guiding mounting groove 104. A lifting assembly 4 is installed in the mounting groove 104. A lifting seat 6 for laying the screen printing plate 3 is also vertically slidably provided in the mounting groove 104. The lifting assembly 4 is connected to the lifting seat 6. In this structure, the lifting assembly 4 includes a motor 401 and a transmission shaft 403. The output end of the motor 401 is connected to the transmission shaft 403 through a gear set 402. The two ends of the transmission shaft 403 are respectively provided with transmission teeth 404. The lifting seat 6 includes a square frame 601. A sliding plate 602 is vertically provided at the end of the square frame 601. The sliding plate 602 is slidably connected to the mounting groove 104. The sliding plate 602 meshes with the transmission teeth 404 through a second rack 603.

[0027] The specific implementation process is as follows: When dual-zone synchronous screen printing of glass plate 10 is required, the lifting conveyor belt 9 lifts and longitudinally transports glass plate 10; after being transported to the screen printing position, the lifting conveyor belt 9 falls, and glass plate 10 is placed above plate body 801; the lifting component 4 is started, and the lifting seat 6 lowers with the screen printing screen 3, and the two screen printing screens 3 abut against the upper ends of glass plate 10; the built-in motor of the translation seat 5 is started, and the translation seat 5 moves laterally along the upper frame 1, and the screen printing squeegees 203 on both sides act on the ends of glass plate 10 to realize the screen printing process; subsequently, the screen printing squeegees 203 are raised, and the adhesive removal squeegees 204 are lowered, and the adhesive removal squeegees 204 act on the ends of glass plate 10 to complete the adhesive removal after the screen printing process; after the equipment is reset, the lifting conveyor belt 9 rises to transport glass plate 10 away.

[0028] Example 2 Reference Figures 1 to 4 Based on Embodiment 1, this embodiment discloses a high-efficiency glass screen printing machine capable of simultaneous screen printing in two zones on a single product. The translation seat 5 is provided with a limiting guide groove 501 in the longitudinal direction. The limiting guide groove 501 and the mounting seat 201 are slidably connected along their length direction and are positioned by bolts. In this structure, the installation position of a pair of screen printing heads 2 on the translation seat 5 is longitudinally adjustable. The installation position of the screen printing heads 2 on the translation seat 5 can be changed by the different longitudinal width of the glass plate 10 or the different positions of the screen printing patterns on the glass plate 10, and can be manually positioned by bolts.

[0029] Example 3 Reference Figures 1 to 6Unlike the above embodiments, this embodiment discloses a high-efficiency glass screen printing machine capable of simultaneous screen printing in two zones on a single product. It includes a mounting plate 7, a lifting conveyor belt 9, a lower frame 8, an upper frame 1, and a screen printing stencil 3. A translation seat 5 is slidably mounted on the upper frame 1. In this structure, the mounting plate 7 is slidably connected to the square frame 601. Both the mounting plate 7 and the square frame 601 are designed to be vertically guided. The screen printing stencil 3 is mounted on the inner side of the mounting plate 7 through a positioning clip 11. A handle 701 is provided on the outer side of the mounting plate 7. The mounting plate 7 is pulled out horizontally from the square frame 601 through the handle 701. The positioning clip 11 is a conventional screen-connected pressure plate. After the positioning clip 11 is released, the screen printing stencil 3 can be vertically removed from the mounting plate 7 for replacement.

[0030] The width of the screen printing stencil 3 is greater than the width of the screen printing head 2, and the screen printing stencil 3 is decorated with a variety of patterns. The mounting plate 7 can be equipped with a longitudinally sliding inner mold frame. The screen printing stencil 3 is installed with the inner side of the inner mold frame through a positioning clip 1, and the mounting plate 7 is installed with the outer side of the inner template through bolts. Relative to the fixed screen printing head 2, the correspondence of the patterns on the screen printing stencil 3 below it can be adjusted horizontally and vertically, so that the screen printing patterns can be changed quickly.
