Description

Technical Field

[0001] This utility model relates to the field of screen printing machine technology, specifically a screen printing machine with rapid positioning capability. Background Technology

[0002] A screen printing machine is a type of printing machine that uses a screen printing plate to apply printing. It can print on the surface of a variety of substrates. There are many types of substrates, one of which is glass. A screen printing machine for printing on glass uses a screen printing plate and glass enamel to perform decorative printing on glass products.

[0003] When a glass screen printing machine prints on a glass plate, the glass plate to be printed needs to be placed on the worktable of the glass screen printing machine. The surface of the worktable is flat. When the glass plate is placed on the worktable, the position of the glass plate needs to be calibrated. If precise positioning cannot be achieved, it will result in incorrect printing pattern position, printing quality problems, and reduced production efficiency of the screen printing machine.

[0004] To overcome the above-mentioned defects, prior art 1 (Chinese patent application number CN202010739708.4, application date 2020-07-28) provides a screen printing machine, which has a worktable and a squeegee on the machine body. The worktable is equipped with a positioning device, an adjustment device, and a support device. The positioning device includes a square positioning frame, which includes two fixed rods, two sliding rods, and a connecting block. The adjustment device can adjust the position of the fixed rods and sliding rods and fix them at the required position. The support device is embedded in the positioning frame and is used to support the substrate, so that the top surface of the substrate is not lower than the top surface of the positioning frame. This allows for quick positioning of the glass plate and achieves accurate positioning of the screen-printed pattern.

[0005] During operation, the aforementioned device cannot dissipate heat from the working area of ​​the screen printing machine, resulting in blurry printed patterns and uneven transfer of ink to the object surface, affecting printing quality and reducing the working efficiency of the screen printing machine.

[0006] To address the aforementioned issues, there is an urgent need for innovative design based on the existing screen printing machine. Utility Model Content

[0007] The purpose of this invention is to provide a screen printing machine that can be quickly positioned to solve the problems mentioned in the background art, such as the inability to dissipate heat from the working area of ​​the screen printing machine, resulting in blurry printed patterns and uneven transfer of ink to the object surface, which affects printing quality and reduces the working efficiency of the screen printing machine.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a screen printing machine capable of rapid positioning, comprising a base and a motor, wherein a sliding plate is fixedly connected to the upper surface of the base, and a moving block is movably connected to the front side of the sliding plate, and a fixed plate is fixedly connected to the front side of the moving block; and a working plate is fixedly connected to the upper surface of the base.

[0009] The surface of the work plate is fixedly connected to a first fixing block, and the interior of the first fixing block is movably connected to a second rotating shaft. The surface of the work plate is fixedly connected to a second fixing block, and the interior of the second fixing block is movably connected to a third rotating shaft.

[0010] Also includes:

[0012] The working plate is internally connected to a threaded rod, and the surface of the threaded rod is movably connected to a clamping plate.

[0013] Preferably, a U-shaped column is fixedly connected to the lower end of the fixing plate, and a printing plate is movably connected inside the U-shaped column, and a positioning column is slidably connected inside the fixing plate.

[0014] Preferably, the other end of the positioning post is fixedly connected to the upper surface of the working plate.

[0015] Preferably, a first spring is fixedly connected to the surface of the printed circuit board, and the other end of the first spring is fixedly connected to the U-shaped column.

[0016] Preferably, a first pulley is sleeved and connected to the surface of the second rotating shaft, and the other end of the first pulley is sleeved and connected to the threaded rod, and the threaded rod 15 is threadedly connected to the clamping plate 16.

[0017] Preferably, a first fan is fixedly connected to the end of the second rotating shaft, and a second pulley is sleeved and connected to the surface of the second rotating shaft.

[0018] Preferably, the other end of the second pulley is fitted with the third rotating shaft, and the end of the third rotating shaft is fixedly connected to the second fan.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this screen printing machine with rapid positioning adopts a novel structural design, the specific details of which are as follows:

[0020] This screen printing machine with rapid positioning has a No. 1 fan installed at the end of the No. 2 rotating shaft to dissipate heat from the working area of ​​the screen printing machine, reduce the surface temperature of the components, prevent damage due to overheating, and ensure that the screen printing machine can work stably for a long time. At the same time, a No. 2 pulley is fitted on the surface of the No. 2 rotating shaft so that the No. 2 fan can cool the surface of the printed object to improve the ink drying quality and reduce impurity contamination.

[0021] Furthermore, the positioning column can accurately determine the position of the fixed plate relative to the working plate, which strengthens the overall structure of the screen printing machine and improves the working efficiency of the screen printing machine.

[0022] This screen printing machine with rapid positioning features a No. 1 spring that retracts into the U-shaped column when the printing plate contacts the work plate, acting as a buffer and preventing damage to the printing plate due to excessive impact. This allows the printing plate to smoothly return to its initial position, ensuring the stability and accuracy of the printing operation.

[0023] Furthermore, the U-shaped column ensures that the printing plate can move relatively stably up and down or swing slightly inside, thus improving the printing quality.

[0024] (3) When the screen printing machine is working, the No. 1 shaft at the output end of the motor drives the bevel gear and the No. 2 shaft to rotate, and the No. 1 pulley is sleeved on the surface of the No. 2 shaft, which drives the threaded rod to rotate, so that the clamping plate fixes the object, ensuring the accuracy of screen printing and improving the versatility of the screen printing machine.

[0032] 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.

[0033] Example 1: By connecting the clamping plate 16, the threaded rod 15, and the working plate 3, the stability of the screen printing machine during operation is improved, such as... Figures 1-2 As shown:

[0034] The device includes a base 1 and a motor 8. A sliding plate 20 is fixedly connected to the upper surface of the base 1, and a moving block 2 is movably connected to the front side of the sliding plate 20. A fixed plate 21 is fixedly connected to the front side of the moving block 2. A working plate 3 is fixedly connected to the upper surface of the base 1. A first fixed block 11 is fixedly connected to the surface of the working plate 3. A second rotating shaft 12 is movably connected inside the first fixed block 11. A second fixed block 13 is fixedly connected to the surface of the working plate 3. A third rotating shaft 22 is movably connected inside the second fixed block 13.

[0035] Also includes:

[0036] The motor 8 is fixedly connected to the surface of the base 1, and the output end of the motor 8 is fixedly connected to a first rotating shaft 9. The surface of the first rotating shaft 9 and the surface of the second rotating shaft 12 are both fixedly connected to bevel gears 10. The inside of the working plate 3 is movably connected to a threaded rod 15, and the surface of the threaded rod 15 is movably connected to a clamping plate 16.

[0037] When the screen printing machine is working, the first rotating shaft 9 at the output end of the motor 8 drives the bevel gear 10 and the second rotating shaft 12 to rotate. The first pulley 14 is sleeved on the surface of the second rotating shaft 12, which drives the threaded rod 15 to rotate, so that the clamping plate 16 fixes the object. The clamping plate 16 can be adjusted according to the size, thereby restricting the freedom of the object during the screen printing process, preventing it from shifting or shaking, ensuring the accuracy of screen printing, and improving the versatility of the screen printing machine.

[0038] Example 2: In this example, unlike Example 1, the protection of the screen printing machine is improved by connecting the U-shaped post 5, the first spring 6, and the printing plate 4. Figure 3 As shown:

[0039] A U-shaped column 5 is fixedly connected to the lower end of the fixed plate 21, and a printing plate 4 is movably connected inside the U-shaped column 5. A positioning column 7 is slidably connected inside the fixed plate 21. The other end of the positioning column 7 is fixedly connected to the upper surface of the working plate 3. A No. 6 spring is fixedly connected to the surface of the printing plate 4, and the other end of the No. 6 spring is fixedly connected to the U-shaped column 5.

[0040] When the screen printing machine prints on an object, when the printing plate 4 comes into contact with the working plate 3, the first spring 6 retracts into the U-shaped column 5, which acts as a buffer and prevents the printing plate 4 from being damaged by excessive impact. It also helps the printing plate 4 to smoothly return to its initial position or make fine adjustments within a suitable range, ensuring the stability and accuracy of the printing operation. In addition, the positioning column 7 can accurately determine the position of the fixed plate 21 relative to the working plate 3, which strengthens the overall integrity of the screen printing machine structure. When the various parts of the screen printing machine work together, this connection method makes the relationship between the various parts closer and more coordinated.

[0041] In Example 3, unlike Example 2, the working efficiency of the screen printing machine is improved by connecting the second pulley 18, the second fan 19, and the first fan 17. Figures 4-6 As shown:

[0042] A first pulley 14 is sleeved on the surface of the second rotating shaft 12, and a threaded rod 15 is sleeved on the other end of the first pulley 14. The threaded rod 15 is threadedly connected to the clamping plate 16. A first fan 17 is fixedly connected to the end of the second rotating shaft 12, and a second pulley 18 is sleeved on the surface of the second rotating shaft 12. A third rotating shaft 22 is sleeved on the other end of the second pulley 18, and a second fan 19 is fixedly connected to the end of the third rotating shaft 22.

[0043] During screen printing, the No. 1 rotating shaft 9 at the output end of the motor 8 drives the bevel gear 10 and the No. 2 rotating shaft 12 to rotate. A No. 1 fan 17 is installed at the end of the No. 2 rotating shaft 12. The No. 1 fan 17 dissipates heat from the working area of ​​the screen printing machine, reduces the surface temperature of the components, prevents damage due to overheating, and ensures that the screen printing machine can work stably for a long time. At the same time, a No. 2 pulley 18 is fitted on the surface of the No. 2 rotating shaft 12, so that the No. 2 fan 19 cools the surface of the printed object, improves the ink drying quality, reduces impurity contamination, and improves the working efficiency of the screen printing machine.

[0044] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
