[0033] This utility model provides a printing scraper assembly 100. For details, please refer to... Figures 1 to 2In this embodiment, the printing squeegee assembly 100 includes a squeegee holder 1, a clamping plate 2, and a squeegee 3. The squeegee holder 1 has a mounting surface 121 and a first wall surface 1111 disposed at a first angle to the mounting surface 121, the mounting surface 121 being adapted to be parallel to the printing surface. The clamping plate 2 is detachably connected to the squeegee holder 1 and has a second wall surface 21 disposed at a relative distance from the first wall surface 1111. The squeegee 3 is clamped between the first wall surface 1111 and the second wall surface 21, such that the central axis of the squeegee 3 is maintained at a first angle to the mounting surface 121.

[0034] In this embodiment, the mounting surface 121 is adapted to be parallel to the printing surface to ensure that after the printing squeegee assembly 100 is installed on the printing press, the first wall surface 1111 can form a first angle with the printing surface, thereby accurately ensuring the angle of the squeegee 3. The first angle can be set according to actual printing needs to meet different printing requirements. The clamping plate 2 is used to cooperate with the squeegee holder 1 to jointly clamp and fix the squeegee 3. The clamping plate 2 is detachably connected to the squeegee holder 1 to facilitate the replacement and maintenance of different squeegee 3. Moreover, when the squeegee 3 is clamped and fixed between the first wall surface 1111 and the second wall surface 21, the central axis of the squeegee 3 can be kept at a first angle with the mounting surface 121, so that the squeegee 3 can print while maintaining a first angle with the printing surface to meet the printing requirements of the specified printed parts. Since the angle between the first wall surface 1111 and the mounting surface 121 is fixed, the printing angle of the scraper 3 is fixed after it is installed on the first wall surface 1111 of the blade holder 1. The operator does not need to repeatedly adjust the angle, making the operation simpler and more convenient. It can ensure the accuracy of adjustment while effectively improving the adjustment efficiency.

[0035] The tool holder 1 is generally arranged in the shape of a long rectangular block. The tool holder 1 has a length direction, a width direction, and a height direction. When the tool holder 1 is placed on a horizontal plane, its length extends horizontally, its width extends forward-backward, and its height extends vertically. Unless otherwise specified, the descriptions of orientations in this invention are based on the above. Figure 1 and Figure 3 As shown, the first included angle is θ, where θ can be between 50° and 90°, such as 55°, 60°, 65°, 70°, 75°, 80°, etc., which can better meet the printing needs of products with different thicknesses.

[0036] Combination Figure 2 and Figure 3As shown, a first groove 111 is provided on the tool holder 1, extending along the length direction of the tool holder 1. A first wall surface 1111 is formed on the side wall of the first groove 111 and extends along the length direction of the tool holder 1, with the first groove 111 penetrating the tool holder 1 at both ends along the length direction of the tool holder 1. The side of the first groove 111 opposite to the first wall surface 1111 is open, that is, the first groove 111 only has a bottom wall and a side wall. A clamping plate 2 is located on the open side of the first groove 111 to clamp and fix the scraper 3 in the first groove 111, and to allow at least a portion of the scraper 3 to protrude from the opening of the first groove 111. When placing the scraper 3, one end of the scraper 3 can be placed in the first groove 111, with one side of the scraper 3 adhering to the first wall surface 1111. Then, by installing the clamping plate 2, the clamping plate 2 and the first wall surface 1111 together clamp the two sides of the scraper 3, thereby fixing the scraper 3 to the blade holder 1. Moreover, the end of the scraper 3 used for scraping ink extends out of the first groove 111, which facilitates the scraping of ink and makes the ink spread evenly.

[0037] It is understood that the clamping plate 2 can be connected to the portion of the tool holder 1 located outside the first groove 111. For example, the clamping plate 2 can be connected to the portion of the tool holder 1 located on the peripheral area of ​​the open side of the first groove 111. This allows the scraper 3 to be fixed to the tool holder 1 via the clamping plate 2. Alternatively, the tool holder 1 can be provided with multiple positioning parts, which can quickly define the setting area of ​​the clamping plate 2, thereby enabling the clamping plate 2 to be quickly positioned when installed on the tool holder 1, resulting in more efficient installation. The positioning parts can be configured as positioning holes, positioning pins, and / or positioning slots, etc.

[0038] Preferably, combined again Figure 2 and Figure 3 As shown, a second groove 112 is also provided on the blade holder 1. The second groove 112 and the first groove 111 are arranged adjacent to each other along the height direction of the blade holder 1, such that the bottom of the first groove 111 and one sidewall of the second groove 112 together form a stepped portion. The clamping plate 2 is disposed in the second groove 112 and can at least partially extend out of the second groove 112 to clamp the scraper 3 on the side facing away from the first wall surface 1111. When placing the clamping plate 2, the clamping plate 2 can be placed corresponding to the second groove 112. When the clamping plate 2 is completely pressed against the scraper 3, the clamping plate 2 and the blade holder 1 are then connected and fixed to lock the scraper 3.

[0039] Specifically, the wall surface of the step portion formed by the second groove 112 is designated as the first step surface 1121. A mounting portion 1122 is provided on the first step surface 1121, and a mating portion 22 is provided on the clamping plate 2. The mounting portion 1122 and the mating portion 22 cooperate to connect and fix the blade holder 1 and the clamping plate 2. Through the mounting portion 1122 and the mating portion 22, the clamping plate 2 and the blade holder 1 can be quickly disassembled and assembled, facilitating the replacement of the scraper component 3 and the maintenance of the scraper component 3, thereby improving the efficiency of disassembly and assembly of the scraper component 3.

[0040] Preferably, combined with Figure 1 and Figure 3 As shown, the mounting part 1122 includes a plurality of first mounting holes 1122a provided on the first stepped surface 1121, and the plurality of first mounting holes 1122a are spaced apart along the length direction of the blade holder 1. The mating part 22 includes a plurality of second mounting holes 221 provided on the clamping plate 2, and the plurality of second mounting holes 221 and the plurality of first mounting holes 1122a are provided in a one-to-one correspondence. The printing blade assembly 100 also includes a plurality of connectors, which are respectively inserted into the plurality of first mounting holes 1122a and the plurality of second mounting holes 221 to connect and fix the blade holder 1 and the clamping plate 2. The connectors can be screws or bolts, etc. By having the plurality of bolts respectively inserted into the plurality of first mounting holes 1122a and the plurality of second mounting holes 221, the clamping plate 2 and the blade holder 1 are locked at multiple points along the length direction, which can ensure a more uniform distribution of clamping force on the blade 3, thereby making the blade 3 more stable and less prone to shaking.

[0041] Moreover, such as Figure 4 As shown, a rough region 23 is formed on the second wall surface 21. The rough region 23 is located outside the second groove 112 for contact with the scraper 3, resulting in a higher coefficient of friction between the scraper 3 and the second wall surface 21, thus better ensuring that the scraper 3 does not move relative to the second wall surface 21. The rough region 23 may have an uneven structure, such as multiple concave points and / or multiple convex points. Alternatively, the rough region 23 may be a frosted surface. Or, the rough region 23 may have a knurled surface design.

[0042] The clamping plate 2 is generally arranged in the shape of a long strip of flat plate, and the length of the clamping plate 2 is adapted to the length of the tool holder 1. The mating part 22 is located outside the rough area 23, so that multiple second mounting holes 221 are located at the bottom of the clamping plate 2, so that the clamping plate 2 can be better aligned with the bottom surface of the second groove 112 and the first step surface 1121 when placed, thereby making the assembly operation more convenient when locking screws or bolts.

[0043] Moreover, combined Figures 1 to 3As shown, a first protrusion 1112 protrudes from the first wall surface 1111. The first protrusion 1112 extends along the length of the blade holder 1 and is positioned close to the opening of the first groove 111. This allows the first protrusion 1112 to abut against the side of the scraper 3 when the scraper 3 is fixed within the first groove 111, resulting in a smaller contact area between the first wall surface 1111 and the scraper 3. Consequently, the pressing force on the scraper 3 is greater, better preventing displacement of the scraper 3. The first protrusion 1112 can be made of stainless steel, which is resistant to deformation under prolonged pressure.

[0044] The blade holder 1 includes a main body 11 and a base 12 connected to the main body 11. A first groove 111 and a second groove 112 are both provided on the main body 11, and a mounting surface 121 is provided on the side of the base 12 facing away from the main body 11. Dividing the blade holder 1 into two parts allows for better replacement of different main bodies 11, enabling the scraper 3 to be positioned at different printing tilt angles; it also makes the mounting surface 121 easier to process, resulting in a flatter mounting surface 121.

[0045] It is understandable that this is done to better adapt to the needs of scraping at more angles. In other embodiments, multiple first wall surfaces 1111 can be provided, or the first wall surface 1111 can be made rotatable to better accommodate different tilt angles in order to adjust the angle of the scraper 3.

[0046] In one embodiment, two first wall surfaces 1111 are provided, and the two first wall surfaces 1111 are respectively provided on both sides of the blade holder 1 along its width direction. That is, the two first wall surfaces 1111 can adapt to two different printing angle requirements.

[0047] In this design, the included angles between the two first wall surfaces 1111 and the mounting surface 121 are the same. If one of the first wall surfaces 1111 is worn or damaged, it can be temporarily replaced by the other wall surface to avoid downtime. Alternatively, the included angles between the two first wall surfaces 1111 and the mounting surface 121 are not the same, so that one blade holder 1 can be adapted to two different scraping angles.

[0048] In another embodiment, the clamping plate 2 can be movably mounted on the blade holder 1. This allows the clamping plate 2 to have a travel distance that moves closer to or further away from the first wall surface 1111, thereby adjusting the distance between the clamping plate 2 and the first wall surface 1111. This allows the printing squeegee assembly 100 to be adapted to the use requirements of squeegee pieces 3 of different thicknesses, ensuring that the squeegee piece 3 is more stably fixed on the blade holder 1.

[0049] Of course, identification symbols, such as laser QR codes, can also be set on the blade holder 1, so that each printing blade assembly 100 has a unique identification code, which facilitates lifespan management and operation traceability. Preferably, the identification symbol is set on one end face of the main body 11 along its length, and an angle can be marked on it to facilitate the operator to pick up the blade holder 1 at the corresponding angle.

[0050] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
