Description

Technical Field

[0001] The utility model relates to an ink scraper, in particular to a convenient ink scraper with a pin hole for quick positioning. Background Art

[0002] Scraper, a thin sheet (metallic and non-metallic) used on a printing press to scrape off excess ink from the surface of the cylinder. Removing ink from unpatterned areas is a key point in every printing process. In offset printing, this control is a complex process of ink transfer, including ink, plate and paper. In gravure printing, it is a mechanical operation, relatively simple, but it has its own uniqueness. The ink scraper must be wear-resistant and efficient to ensure high quality printing.

[0003] However, even if the material of the scraper blade itself has a certain wear resistance, it will still wear out after being used for a certain period of time, resulting in a reduction in the scraping effect of the scraper blade, affecting the subsequent printing effect. Therefore, the scraper blade needs to be replaced regularly. The existing scraper blade is directly fixed on the aluminum plate. When replacing it, the staff needs to use auxiliary work to dismantle it, and then install a new scraper blade, resulting in low disassembly and assembly efficiency. Utility Model Content

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0017] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0018] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0019] See also Figure 1-Figure 2 In an embodiment of the utility model, a convenient pin hole quick positioning scraper comprises a mounting plate 5 and a mounting seat 6, wherein the mounting seat 6 is detachably mounted with a scraper 7, thereby enabling the scraper 7 to be separated from the mounting seat 6 and improving the efficiency of tool change; a pin hole 16 is formed on the mounting plate 5, a pin shaft 13 passing through the mounting seat 6 can be inserted into the pin hole 16, a wire screw sleeve 14 communicating with the inner side of the pin hole 16 is arranged on the mounting plate 5 along the inclined direction of the pin hole 16, and the wire screw sleeve 14 is internally threadedly connected with a threaded pressure rod 15 which can be pressed or separated from the pin shaft 13.

[0020] In this embodiment, after the pin shaft 13 is inserted into the pin hole 16, the threaded pressure rod 15 can be manually rotated to move the threaded pressure rod 15 toward the inner side of the pin hole 16, and finally the end of the threaded pressure rod 15 is abutted and pressed against the pin shaft 13, thereby generating a radial force on the pin shaft 13, thereby fixing the pin shaft 13, improving the installation stability, facilitating disassembly and assembly, and improving the efficiency of tool changing.

[0021] Among them, it should be supplemented that a conical protrusion is formed on one end of the threaded rod 15 facing the pin hole 16, and the conical protrusion can eventually be pressed and fixed with the pin shaft 13. A handle is formed on the end of the threaded rod 15 away from the pin hole 16. The threaded rod 15 is rotated by the handle shell, and the handle is known to be above the mounting plate 5. Therefore, no other auxiliary tools are required when rotating the threaded rod 15.

[0022] The wire screw sleeve 14 described above is threadedly connected to an inclined through hole formed on the mounting plate 5 , and the inclined through hole is communicated with the pin hole 16 . When the wire screw sleeve 14 is tightened in the inclined through hole, the wire screw sleeve 14 and the pin hole 16 remain in a communicated state.

[0023] For further information, see Figure 1 A slide 4 is fixed on the mounting plate 5, and the slide 4 is slidably mounted on the frame 1 and connected to an adjusting member mounted on the frame 1. Exemplarily, in one embodiment, the adjusting member includes a threaded rod 3 rotatably mounted on the frame 1, a handwheel 2 is fixed to one end of the threaded rod 3, and the other end is inserted into a threaded hole formed on the slide 4 and threadedly connected to the threaded hole.

[0024] The threaded rod 3 can be driven to rotate by rotating the handwheel 2. When the threaded rod 3 rotates, the threaded hole on the slide 4 cooperates to realize the axial movement of the slide 4 along the threaded rod 3, thereby driving the entire body installed on the slide 4 (including but not limited to the mounting plate 5 and the mounting seat 6 installed on the mounting plate 5) to move, thereby realizing the position adjustment of the scraper 7 to meet different scraping requirements.

[0025] For further information, see Figure 2 A fixed shaft 10 is fixed on the mounting seat 6, and a locking plate 9 is sleeved on the fixed shaft 10 and limited by a limit piece 11. One end of the locking plate 9 is pressed on the scraper 7 placed on the mounting seat 6, and the other end is in contact with a locking adjustment piece arranged on the mounting seat 6. The through groove on the locking plate 9 for the fixed shaft 10 to pass through has a larger area than the radial section of the fixed shaft 10, so that the locking plate 9 can change its position at a certain angle relative to the fixed shaft 10. When the locking adjustment piece pushes one end of the locking plate 9 upward, the other end of the locking plate 9 rotates downward and presses on the scraper 7, thereby fixing the scraper 7. There is no need to fix the scraper 7 with screws, etc., which can effectively improve the convenience of disassembly and assembly of the scraper 7.

[0026] Preferably, in order to improve the stability of the scraper 7 after installation, a pressure plate 8 is further provided on the side of the scraper 7 away from the mounting seat 6, and the side of the pressure plate 8 away from the scraper 7 abuts against the locking plate 9. The pressure plate 8 can effectively increase the force area of ​​the scraper 7 away from the mounting seat 6 to ensure that the scraper 7 will not deflect when performing the scraping action, thereby effectively improving the scraping effect of the scraper 7 when performing the scraping action.

[0027] Among them, the fixed shaft 10 is a fixed screw, the limiting member 11 is a fixed screw sleeve, the fixed shaft 10 is threadedly connected to the limiting member 11, and the axial position of the limiting member 11 relative to the fixed shaft 10 can be adjusted by rotating the limiting member 11, so as to maintain the clamping effect of the locking plate 9 on the pressure plate 8 when the locking plate 9 undergoes permanent deformation, without the need for frequent replacement, which effectively saves production costs.

[0028] In one embodiment, the locking adjustment member includes a locking wheel 12 rotatably mounted on the mounting seat 6, and the locking wheel 12 is formed with a flat surface 1201; when the flat surface 1201 is facing the locking plate 9, the locking plate 9 loses the clamping force on the pressure plate 8, and when the flat surface 1201 and the locking plate 9 are turned away, an upward thrust is generated on the locking plate 9, and the other end of the locking plate 9 is rotated downward and pressed onto the pressure plate 8, thereby fixing the scraper 7.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
