[0053] Combination Figure 10 As shown, in the prior art, the scraper 8 is fixed on the scraper holder 7 during use. The scraper holder 7 has two slots on the side away from the scraper 8, namely the first slot 71 and the second slot 72. The openings of the first slot 71 and the second slot 72 face the same side, which makes it easy to hang the scraper holder 7 on the printing machine.

[0054] In the first aspect, combining Figures 1 to 10 This disclosure provides a fixing device for scraper cleaning and flatness testing. The fixing device for scraper cleaning and flatness testing includes a mounting frame 1, an adjusting rod 2, a first fixing part 3, and a second fixing part 4.

[0055] The mounting frame 1 has a rectangular frame structure, and the size of the mounting frame 1 is consistent with the size of the steel mesh. This makes it easy to place the mounting frame 1 into the steel mesh cleaning machine for double-sided spray cleaning.

[0056] The adjusting rod 2 has a plate-like structure and is set on the mounting frame 1. Specifically, the left and right ends of the adjusting rod 2 are connected to the left and right sides of the mounting frame 1, respectively, and the adjusting rod 2 is located in the middle of the mounting frame 1.

[0057] Specifically, the mounting frame 1 and the adjusting rod 2 are made of aluminum, and the materials used for the mounting frame 1 and the adjusting rod 2 include, but are not limited to, aluminum.

[0058] The first fixing part 3 is fixedly disposed on the adjusting rod 2. The first fixing part 3 is configured to pass through the first slot 71 on the scraper seat 7 to fix one end of the scraper seat 7.

[0059] The second fixing part 4 is provided on the adjusting rod 2. The second fixing part 4 is configured to pass through the second slot 72 on the scraper seat 7 to fix the other end of the scraper seat 7. The distance between the second fixing part 4 and the first fixing part 3 is adjustable, so that the distance between the first fixing part 3 and the second fixing part 4 is equal to the distance between the first slot 71 and the second slot 72, which is convenient for fixing various types of scraper seats 7 and expands the scope of application.

[0060] Specifically, when the scraper 8 needs to be cleaned, the scraper seat 7 with the scraper 8 fixed on it is installed on the mounting frame 1, and the mounting frame 1 is placed in the steel mesh cleaning machine for double-sided spray cleaning. No manual cleaning is required, saving manpower; it avoids damage to the scraper 8 due to improper manual cleaning; the cleaning efficiency is high, the cleaning effect is good, and it avoids the operator from coming into contact with the cleaning agent, reducing the harm of the cleaning agent to the operator; at the same time, the scraper seat 7 is fixed to the first fixing part 3 and the second fixing part 4 by a snap-fit ​​method, which is simple and easy to disassemble the scraper seat 7.

[0061] It should be noted that when the mounting frame 1 is placed into the steel mesh cleaning machine, the openings of the first slot 71 and the second slot 72 should be facing downwards to prevent the scraper seat 7 from falling off.

[0062] In some embodiments of this application, the adjusting rod 2 has a groove 21 formed along its length, and the groove 21 is elongated; the first fixing part 3 and the second fixing part 4 both include a main body part 41.

[0063] Combination Figure 2 and Figure 3 As shown, a positioning hole 411 is formed at the position corresponding to the slide groove 21 of the main body 41. The fastener 42 passes through the slide groove 21 and the positioning hole 411 to fix the main body 41 to the adjusting rod 2. A positioning post 412 is provided on the main body 41. The first slot 71 and the second slot 72 are both adapted to the positioning post 412.

[0064] Specifically, by setting a sliding groove 21 along the length of the adjusting rod 2, and setting a positioning hole 411 on the main body 41 at a position corresponding to the sliding groove 21, the positioning hole 411 corresponds to the sliding groove 21. In this way, after the fastener 42 is loosened, both main bodies 41 can slide along the sliding groove 21, which facilitates the adjustment of the distance between the positioning pins 412 on the two main bodies 41, so that the distance between the two positioning pins 412 is equal to the distance between the first slot 71 and the second slot 72.

[0065] Meanwhile, the scraper holder 7 is fixedly connected to the main body 41 by a snap-fit ​​connection, which makes it easy to disassemble the scraper holder 7 and operate it simply and conveniently.

[0066] In order to improve the structural stability of the connection between the main body 41 and the adjusting rod 2, positioning holes 411 are provided at both ends of the main body 41, and each main body 41 is fixedly connected to the adjusting rod 2 by two fasteners 42.

[0067] Specifically, the main body 41 has a T-shaped structure, with two positioning holes 411 arranged symmetrically.

[0068] In some embodiments of this application, combined with Figure 4 As shown, both the first fixing part 3 and the second fixing part 4 also include a stop part 43.

[0069] The stop part 43 is connected to the main body part 41 via the connector 44. The stop part 43 corresponds to the positioning post 412 and is configured to prevent the scraper seat 7 from disengaging from the positioning post 412.

[0070] Specifically, by setting a stop part 43, which is connected to the main body part 41, the stop part 43 can prevent the scraper seat 7 from disengaging from the positioning post 412 along the axial direction of the positioning post 412, thereby improving the stability of the overall structure.

[0071] Specifically, the stop part 43 is rotatably connected to the main body part 41 via the connector 44. Rotating the stop part 43 can adjust the position of the stop part 43 relative to the main body part 41, so as to facilitate the disassembly of the scraper seat 7.

[0072] During the process of placing the mounting frame 1 into the steel mesh cleaning machine, the mounting frame 1 is placed vertically, and the openings of the first slot 71 and the second slot 72 should face downwards. This can prevent the scraper seat 7 from dislodging from the positioning post 412 in the vertical direction.

[0073] In some embodiments of this application, a stepped hole 431 is formed on the stop portion 43, the large hole 4311 of the stepped hole 431 is located above the small hole 4312, the interface between the large hole 4311 and the small hole 4312 is a stepped surface 4313, and the connector 44 includes a connecting post 441, a positioning member 442 and an elastic member 443.

[0074] The connecting column 441 has a columnar structure. The bottom of the connecting column 441 is fixedly connected to the main body 41 by welding. The connecting column 441 passes through the stepped hole 431 and is rotatably connected to the stop part 43.

[0075] The positioning element 442 is threadedly connected to the top of the connecting post 441;

[0076] The elastic element 443 is sleeved on the outside of the connecting post 441. The inner diameter of the elastic element 443 is larger than the size of the small hole 4312, ensuring that the elastic element 443 is in the large hole 4311. The elastic element 443 elastically abuts against the positioning element 442 and the stepped surface 4313 of the stepped hole 431.

[0077] Specifically, the connector 44 includes a connecting post 441, a positioning member 442, and an elastic member 443. The elastic member 443 is sleeved on the outside of the connecting post 441 and elastically abuts against the positioning member 442 and the stepped surface 4313 of the stepped hole 431. In this way, the elastic member 443 applies a force to the stop part 43 in the direction of the main body 41, causing the stop part 43 to press against the main body 41. When the scraper seat 7 is stuck on the positioning post 412 on the main body 41, the stop part 43 is rotated. When the stop part 43 is aligned with the positioning post 412, the stop part 43 will press against the scraper seat 7 under the action of the elastic member 443, preventing the scraper seat 7 from coming out along the axial direction of the connecting post 441.

[0078] For example, the elastic element 443 is a compression spring.

[0079] In some embodiments of this application, a positioning groove 413 is formed on the main body 41 at a position corresponding to the stop 43. The positioning groove 413 is configured to prevent the stop 43 from rotating relative to the main body 41 when the scraper seat 7 is fixed on the main body 41.

[0080] Specifically, by providing a positioning groove 413 on the main body 41 at a position corresponding to the stop 43, when the scraper seat 7 is engaged on the positioning post 412, the stop 43 is rotated. When the stop 43 is aligned with the positioning post 412, the stop 43 will press against the scraper seat 7 under the action of the elastic member 443. At the same time, the bottom of the stop 43 is confined in the positioning groove 413. The positioning groove 413 can prevent the stop 43 from rotating relative to the main body 41, which helps to improve the stability of the overall structure.

[0081] When the scraper holder 7 needs to be removed, lift the stop part 43 upwards, the elastic element 443 is compressed, and at the same time rotate the stop part 43 to disengage the stop part 43 from the positioning groove 413; when the scraper holder 7 is installed, rotate the stop part 43. When the stop part 43 reaches the position of the positioning groove 413, under the elastic force of the elastic element 443, the stop part 43 enters the positioning groove 413.

[0082] In some embodiments of this application, the first plane 414 of the main body 41 that contacts the scraper seat 7 is an inclined plane, the second plane 432 of the stop 43 facing the scraper seat 7 is also an inclined plane, and the first plane 414 and the second plane 432 are parallel, with the scraper seat 7 located between the first plane 414 and the second plane 432.

[0083] Specifically, by setting the first plane 414 of the main body 41 that contacts the scraper seat 7 and the second plane 432 of the stop 43 facing the scraper seat 7 as parallel inclined surfaces, the scraper seat 7 can be better fixed and the stability can be improved.

[0084] Specifically, the angle between the first plane 414 and the second plane 432 and the horizontal direction is α, where α is 30°, 35°, 40°, 45°, 50°, 55°, or 60°. Of course, it can also be set according to actual needs.

[0085] In some embodiments of this application, combined with Figure 6 and Figure 7 As shown, the fixing device used for scraper cleaning and flatness testing also includes a support member 5.

[0086] The support member 5 is fixedly connected to the bottom of the adjusting rod 2, and the support member 5 is configured to support the scraper seat 7.

[0087] Specifically, by setting up support member 5, support member 5 can abut against the bottom of scraper seat 7, better supporting scraper seat 7 and improving the stability of scraper seat 7.

[0088] In some embodiments of this application, the adjusting rod 2 is provided with a scale 22 along its length.

[0089] Specifically, by setting a scale 22 along the length direction on the adjusting rod 2, the user can accurately adjust the distance between the two positioning posts 412 and the position of the main body 41 on the adjusting rod 2.

[0090] Currently, existing scraper 8 mainly observes light transmittance using backlighting, and the test results are greatly affected by human factors. Combined with... Figure 8 As shown, this application allows the installation frame 1 to be placed on a steel mesh scraper testing machine after the scraper 8 is fixed on the mounting frame 1 to test the flatness of the scraper 8. The test results are not affected by human factors and have a high accuracy rate.

[0091] During the flatness test of scraper 8, the mounting frame 1 is placed horizontally in the integrated steel mesh scraper testing machine.

[0092] In some embodiments of this application, one of the mounting frame 1 and the adjusting rod 2 is provided with a sliding groove 21, and the other of the mounting frame 1 and the adjusting rod 2 is provided with a sliding rail. Along the thickness direction of the mounting frame 1, both ends of the adjusting rod 2 are slidably connected to the mounting frame 1 through the sliding groove 21 and the sliding rail.

[0093] Specifically, when the mounting frame 1 is laid flat, the adjusting rod 2 is slidably connected to the mounting frame 1 to facilitate the adjustment of the vertical height of the scraper 8 on the scraper seat 7, so that the camera on the steel mesh scraper testing machine can adjust its focus to test the flatness of the scraper 8.

[0094] In some embodiments of this application, combined with Figure 5As shown, an extension 11 is formed on the mounting frame 1 at a position corresponding to the adjusting rod 2. The extension 11 is located above the adjusting rod 2. When the adjusting rod 2 slides relative to the mounting frame 1, the extension 11 can prevent the adjusting rod 2 from sliding upward and disengaging from the mounting frame 1. A mounting hole is formed on the extension 11, and a threaded hole is formed on the adjusting rod 2. The fixing device for scraper cleaning and flatness testing also includes an adjusting bolt 6.

[0095] The adjusting bolt 6 passes through the mounting hole and the threaded hole in sequence and is threaded to the adjusting rod 2. The nut of the adjusting bolt 6 is located above the mounting hole, and the nut can prevent the adjusting rod from sliding down and disengaging from the mounting frame 1.

[0096] Specifically, an extension 11 is provided on the mounting frame 1 at a position corresponding to the adjusting rod 2. The extension 11 has a mounting hole, and the adjusting rod 2 has a threaded hole. The adjusting bolt 6 passes through the mounting hole and the threaded hole and is threadedly connected to the adjusting rod 2. When testing the flatness of the scraper 8, the mounting frame 1 is placed horizontally in the integrated steel mesh scraper testing machine. The vertical height of the scraper 8 can be adjusted by rotating the adjusting bolt 6. The operation is convenient and it is beneficial for the camera on the integrated steel mesh scraper testing machine to adjust the focus to test the flatness of the scraper 8.

[0097] In other embodiments, the top of the mounting frame 1 and the bottom of the adjusting rod 2 are provided with protrusions to prevent the mounting frame 1 and the adjusting rod 2 from separating.

[0098] The process of fixing the scraper holder 7 is as follows, combined with Figure 1 , Figure 9 and Figure 10 First, place the mounting frame 1 flat on the table; rotate the stop part 43 so that it avoids the position above the positioning post 412, then place the scraper seat 7 on the main body 41 with the scraper 8 facing upwards, so that the first slot 71 and the second slot 72 on the scraper seat 7 are respectively aligned with the positioning posts 412 on the two main body parts 41; rotate the stop part 43 so that it rotates into the positioning groove 413, at which point the stop part 43 covers the top of the positioning post 412, restricting the scraper seat 7 between the main body part 41 and the stop part 43; finally, tighten the fastener 42 to fix the main body part 41 and the adjusting rod 2, and the scraper seat 7 can be installed.

[0099] When cleaning the scraper 8, the mounting frame 1 is placed vertically into the steel mesh cleaning machine. The openings of the first slot 71 and the second slot 72 on the scraper seat 7 should be facing downwards. In this way, the positioning column 412 provides vertical support for the scraper seat 7. After the steel mesh cleaning machine has cleaned and dried the scraper 8, it can be removed.
