[0002] Digital printing presses typically have multiple wiper blade assemblies for wiping residual ink and dust from the printhead surface. Each wiper blade assembly has a wiper blade, and the wiper blades of multiple wiper blade assemblies need to be set at the same height. Therefore, before installing the wiper blade assembly on the digital printing press, it is necessary to measure the height of the wiper blades on the wiper blade assembly. Only when the heights of the wiper blades of multiple wiper blade assemblies are almost equal can they be installed on the digital printing press.

[0003] In the process of realizing this utility model, the inventors discovered that: at present, the main method for testing the scraper blades of the scraper blade assembly is to use a lever gauge. However, the lever gauge requires the user to manually measure each scraper blade one by one, which results in unreliable measurement accuracy and low measurement efficiency. Utility Model Content

[0018] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them.

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0020] Please see Figure 1 The scraper assembly 10 includes a scraper 11, a mounting base 12, and a pressure plate 13. The scraper 11 is provided with a first connecting hole 111, the mounting base 12 is provided with multiple fixing screw holes 121, and the pressure plate 13 is provided with multiple second connecting holes 131. When assembling the scraper assembly 10, a bolt passes through the first connecting hole 111 and a second connecting hole 131 in sequence and is screwed into a fixing screw hole 121. The pressure plate 13 and the mounting base 12 clamp the scraper 11 to form the scraper assembly 10, thereby fixing the scraper 11. When the scraper 11 is clamped and squeezed by the pressure plate 13 and the mounting base 12, the lower end of the scraper 11 will be compressed and thinned, while the upper end of the scraper 11 will bulge, thereby causing a change in the height of the scraper 11. Furthermore, the height change of the scraper blade 11 is affected by the amount of compression at the lower end of the scraper blade 11. Generally, the greater the amount of compression at the lower end of the scraper blade 11, the larger the protrusion of the scraper blade 11. Conversely, the smaller the amount of compression at the lower end of the scraper blade 11, the smaller the protrusion at the upper end of the scraper blade 11.

[0021] like Figure 2 and Figure 3 As shown, Figure 2 This is a graph showing the measurement data corresponding to the compression and protrusion of the 18 scraper blades 11. Figure 3 It is a line graph showing the compression and protrusion amounts corresponding to the 18 scraper blades 11. Figure 2 The horizontal axis represents the serial number of the scraper blade 11, and the vertical axis represents the compression amount of the scraper blade 11. Compression amounts A, B, C, D, and E represent compression amount data for different groups, respectively. The number in the middle represents the amount of protrusion at the upper end of the scraper blade assembly 10. Figure 3In the diagram, the vertical axis represents the amount of protrusion at the top of the 18 scraper blade assemblies 10, the horizontal axis represents the serial number of the 18 scraper blade assemblies 10, and the line is formed by connecting the protrusion amounts corresponding to the compression amounts of the 18 scraper blade assemblies 10. Figure 2 and Figure 3 It can be clearly seen that the compression amount is A > B > C > D > E, and the lines corresponding to compression amounts A, B, C, D, and E are distributed sequentially from top to bottom. That is, the greater the compression amount, the greater the bulge. However, when installing the scraper assembly 10, it is difficult for the operator to precisely control the compression amount of each scraper assembly 10. Therefore, after installing multiple scraper assemblies 10, it is necessary to detect the height of multiple scrapers. When the heights of multiple scrapers 11 are inconsistent and the difference is too large, the user can adjust the compression amount of the scrapers 11 in time to make the heights of multiple scrapers 11 as consistent as possible. For this purpose, a measuring device 20 for measuring the scraper height of the scraper assembly is needed, as follows: Please see Figure 4 and Figure 5 The measuring device 20 includes a detection stage 21, a driving component 23, and an optical detection component 22. The optical detection component 22 is disposed on the detection stage 21, and the driving component 23 is disposed on the detection stage 21. The driving component 23 is used to drive at least one of the scraper components 10 and the optical detection component 22 so that at least one set of scraper components 10 passes through the optical detection component 22. The optical detection component 22 is used to detect the height of at least one set of scraper components to determine whether there is a height difference between the scrapers 11 on the scraper components 10.

[0022] For the optical detection component 22 mentioned above, please refer to Figure 4 and Figure 5 and combined Figure 6 and Figure 7 The optical detection component 22 includes a receiver 222 and a emitter 221, which are arranged opposite to each other. The emitter 221 emits a light beam, and the receiver 222 receives the light beam emitted by the emitter 221. The light beam emitted by the emitter 221 is sheet-like in the vertical direction. When multiple scraper assemblies 10 pass between the receiver 222 and the emitter 221, and the heights of the scraper blades 11 of the multiple scraper assemblies 10 are the same, the heights at which the multiple scraper assemblies 10 block the light beam emitted by the emitter 221 are the same. In other words, when multiple scraper assemblies 10 pass between the receiver 222 and the emitter 221, and the height of the light beam received by the receiver 222 is detected to be the same, it can be determined that the heights of the multiple scraper assemblies 10 are the same; otherwise, it is determined that the heights of the multiple scraper assemblies 10 are not the same.

[0023] Furthermore, the light emitter 221 is also provided with a first through hole 2211 for mounting the light emitter 221. The light receiver 222 is also provided with a second through hole 2221 for mounting the light receiver 222.

[0024] The driving component 23 described above is used to drive one of the scraper assembly 10 and the optical detection assembly 22. Therefore, the driving component 23 can drive the scraper assembly 10 and the optical detection assembly 22 in three ways: (1) At least one set of scraper assemblies 10 is fixed to the detection stage 21, and the driving component 23 drives the optical detection assembly 22 to move so that the scraper assembly passes through the optical detection assembly 22. (2) The optical detection assembly 22 is fixed to the detection stage 21, and the driving component 23 drives at least one set of scraper assemblies 10 to move so that the scraper assembly 10 passes through the optical detection assembly 22. (3) The driving component 23 drives at least one set of scraper assemblies 10 and the optical detection assembly 22 to move relative to each other so that the scraper assembly 10 passes through the optical detection assembly 22. The first method will be used as an example for the following description. The driving assembly 23 includes a support plate 231 and a driving member 232. The support plate 231 is slidably disposed on the detection stage 21, and the driving member 232 is connected to the support plate 231. The driving assembly 23 is used to drive the support plate 231 to move. The light receiver 222 and the light emitter 221 are both disposed on the support plate. When the driving member 232 drives the support plate 231 to move, the support plate 231 drives the light receiver 222 and the light emitter 221 to move. At this time, the scraper assembly 10 is fixed to the detection stage 21. When the scraper assembly 10 passes through the light receiver 222 and the light emitter 221, the optical detection assembly 22 can detect the height of the scraper 11 of at least one set of scraper assemblies 10, thereby determining whether there is a height difference in the scraper assembly 10.

[0025] In some embodiments, the driving component 232 includes a mounting bracket 2321, a protrusion 2322, a lead screw 2323, and a rotating component 2324. The protrusion 2322 is fixed to the support plate 231 and has a screw hole (not shown). The mounting bracket 2321 is fixed to the detection stage 21. The rotating component 2324 is fixed to the mounting bracket 2312. The rotating component 2324 is connected to one end of the lead screw 2323. The lead screw 2323 is screwed and passes through the screw hole. When the rotating component 2324 drives the lead screw 2323 to rotate, the lead screw 2323 drives the protrusion 2322 to move linearly under the cooperation of the lead screw 2323 and the protrusion 2322, thereby driving the support plate 231 to move linearly, and then driving the optical detection component 22 to move linearly.

[0026] In some embodiments, the rotating component 2324 is a motor. When the rotating component 2324 is a motor, a potentiometer (not shown) can also be provided to adjust the speed of the motor to prevent the motor speed from being too fast, which would cause the scraper assembly 10 to move too quickly and pass through the optical detection assembly 22 instantaneously, which would be detrimental to the detection by the optical detection assembly 22. Furthermore, the measuring device 20 also includes two limit switches (not shown). The two limit switches are positioned relative to the detection stage 21. The two limit switches are used to detect the maximum stroke of the support plate 231, thereby detecting the maximum stroke of the optical detection assembly 22. Specifically, when the motor starts rotating forward, the potentiometer adjusts the speed, and the motor rotates forward. The support plate 231 moves to one side. When the limit switch on one side detects the support plate, it indicates that the movement of the support plate 231 to one side has reached its maximum stroke, and the motor stops rotating. When the motor starts rotating in reverse, the potentiometer adjusts the speed, and the motor rotates in reverse. The support plate 231 moves to the other side. When the limit switch on the other side detects the support plate 231, it indicates that the movement of the support plate 231 to the other side has reached its maximum stroke, and the motor stops rotating.

[0027] Furthermore, the drive assembly 23 includes a slide rail 2325 and a slider 2326. The slide rail 2325 is disposed on the detection stage 21, and the slider 2326 is disposed on the support plate 231. The slider 2326 is slidably disposed on the slide rail 2325. The slider 2326 and the slide rail 2325 make the sliding of the support plate 231 smoother.

[0028] In some embodiments, the number of slide rails 2325 and sliders 2326 is at least two, with at least two slide rails 2325 arranged opposite to each other, and a slider 2326 slidably disposed on a slide rail 2325. The arrangement of at least two sets of slide rails 2325 and sliders 2326 facilitates the smooth sliding of the support plate 231.

[0029] It is understood that in some other embodiments, the slide rail 2325 may be disposed on the support plate 231 and the slider 2326 may be disposed on the detection stage 21.

[0030] In some embodiments, please refer to Figure 5 and combined Figure 8 and Figure 9The drive assembly 23 further includes a first support 233, a second support 234, a first bolt (not shown), and a second bolt (not shown). The first support 233 and the second support 234 are fixed relative to the support plate 231. The first support 233 is provided with a first screw hole 2331, and the second support 234 is provided with a second screw hole 2341. The first bolt is used to pass through the first through hole 2211 and screw into the first screw hole 2331, thereby fixing the emitter 221 to the support plate 231. The second bolt is used to pass through the second through hole 2221 and screw into the second screw hole 2341, thereby fixing the receiver 222 to the support plate 231.

[0031] In some embodiments, there are multiple first screw holes 2331, which are spaced apart along the height direction of the first support 233. Therefore, the height of the emitter 221 can be adjusted by adjusting the first bolts screwed into different first screw holes 2331. Similarly, there are multiple second screw holes 2341, which are spaced apart along the height direction of the second support 234. The height of the receiver 31 can also be adjusted by adjusting the second bolts screwed into different second screw holes 2341.

[0032] It is worth noting that the first screw hole 2331 and the second screw hole 2431 are aligned horizontally to ensure that the light emitter 221 and the light receiver 222 are at the same height when they are installed.

[0033] Mounting bracket 2321 is also provided with a third screw hole 2321A, which is used to mount mounting bracket 2321 onto testing table 21.

[0034] For the aforementioned testing station 21, please refer to Figure 5 and combined Figure 10 The testing platform 21 includes a support leg 211 and a top plate 212. The top plate 212 is fixed to the support leg 211, and the support leg 211 supports the top plate 212. The top plate 212 is provided with a strip-shaped hole 2121, so that the testing platform 21 is provided with a strip-shaped hole 221. The strip-shaped hole 2121 extends along the sliding direction of the bearing plate 231. The measuring device 20 includes a third bolt (not shown). The third bolt is used to pass through the strip-shaped hole 2121 and be screwed into the third screw hole 2321A. When the third bolt is in the unlocked state, the mounting bracket 2321 can slide relative to the testing platform 21 to adjust the position of the driving member 232. When the third bolt is in the locked state, the mounting bracket 2321 is fixed to the testing platform 21.

[0035] In some embodiments, the measuring device further includes a mounting platform 24 disposed on the detection platform 21, the mounting platform 24 having a groove 241 for mounting the scraper assembly 10.

[0036] In this embodiment of the present invention, the measuring device 20 includes a detection stage 21, a driving component 23, and an optical detection component 22. The detection stage 21 is used to support at least one set of scraper assemblies 10. The optical detection component 22 is disposed on the detection stage 21. The driving component 23 is used to drive one of the scraper assembly 10 and the optical detection component 22 so that the scraper assembly 10 passes between the light receiver 222 and the light emitter 221. When the scraper assembly 10 passes between the light receiver 222 and the light emitter 221, the light receiver 222 and the light emitter 221 can detect the height of the scraper 11 of at least one set of scraper assemblies 10, and can also detect whether there is a height difference between multiple scrapers 11 of multiple sets of scraper assemblies 10, thereby realizing automatic detection of the scraper assembly 10. Moreover, the measurement accuracy using the optical detection component 22 is higher.
