Description

Technical Field

[0001] The utility model belongs to the technical field of printing auxiliary equipment, and in particular relates to a printing scraper detection device. Background Art

[0002] During the printing process, a scraper moves over the printing plate, keeping close contact with the plate surface. As it moves, it scrapes away excess ink, leaving only the ink covering the image. This transfers the ink to the substrate when it comes into contact with the plate, completing the print.

[0003] Defects on the scraper blade can lead to inconsistent scraping force, resulting in uneven ink thickness on the printing plate. If the scraper has a chip or severely worn area, it may not completely remove excess ink from the printing plate, causing ink to remain in non-image areas and leaking ink during printing. This can cause blurred or dirty areas on the printed product, reducing print quality. A defective scraper may not be able to accurately remove fine ink particles from the printing plate, resulting in blurred and unclear lines on the printed product. This is especially problematic when printing fine patterns and text. Therefore, the flatness of the scraper blade needs to be tested before it is put into production line.

[0004] The existing scraper detection device (such as 201320598285.4, circuit printing scraper detection workbench) requires the scraper to be fixed first, then the height is adjusted, and the defects are judged by light exposure. This method is cumbersome to operate and greatly reduces the efficiency of scraper detection. Utility Model Content

[0005] The purpose of the utility model is to provide a printing scraper detection device to solve the problem of low scraper detection efficiency.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a printing scraper detection device, comprising a workbench, a No. 1 slot being horizontally provided on the top of the workbench, a No. 2 slot and a No. 3 slot being respectively provided on both sides of the No. 1 slot, an image acquisition sensor being provided on the side of the workbench close to the No. 2 slot, a plurality of light source generating devices being provided in the No. 3 slot, a sealing block being movably provided inside the No. 1 slot, a mounting bracket being connected to the top of the workbench, and a rolling shaft being provided on the mounting bracket.

[0007] Furthermore, the right opening of the No. 1 slot is arc-shaped.

[0008] Furthermore, the light source emitted by the light source generating device has a color.

[0009] Furthermore, the light source emitted by the light source generating device is in an interval shape, and the interval light sources emitted by a plurality of the light source generating devices are arranged to cross and overlap with each other.

[0010] Furthermore, a connecting block is connected to one side of the top of the workbench, and the connecting block is arranged perpendicular to the No. 1 groove. The right side of the connecting block is laterally connected to a transverse rod, and the transverse rod is located directly above the No. 1 groove, and the transverse rod and the No. 1 groove are parallel to each other. The transverse rod is movably connected to a sealing block.

[0011] Furthermore, the sealing block is T-shaped.

[0012] Furthermore, an elastic member is sleeved on the transverse rod, and two ends of the elastic member respectively abut against the connecting block and the sealing block.

[0013] Furthermore, the side wall of the sealing block in contact with the second groove is elastic.

[0014] Furthermore, a bolt is threadedly sleeved on the mounting frame, and a U-shaped part is provided inside the mounting frame, the opening of the U-shaped part is set downward, and a plurality of rolling shafts are provided at the bottom opening of the U-shaped part, and the U-shaped part is movably sleeved on the bottom of the bolt, and the workbench is located at both sides of the No. 1 slot and is vertically connected with vertical rods, and both sides of the U-shaped part are movably sleeved on the vertical rods.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The printing scraper detection device forms an insertion-type detection by setting up a specially structured workbench, an image acquisition sensor, a light source generating device, a sealing block, etc., which can quickly and accurately detect whether the scraper has defects, thereby improving the efficiency of scraper detection.

[0017] In the printing scraper detection device, the side wall where the sealing block contacts the No. 2 groove is elastic, which has a sealing effect, reduces the entry of external natural light into the No. 2 groove, and keeps the No. 2 groove in a dark environment, which is beneficial for the image acquisition sensor to identify the light emitted by the light source generating device, thereby improving the accuracy of detection.

[0018] This printing scraper detection device, through the cooperation of components such as the mounting frame, bolts, U-shaped parts and rolling shafts, can limit the vertical movement space of the scraper, so that the bottom of the scraper is always in contact with the bottom of the inner cavity of groove No. 1, ensuring the stability and reliability of the detection.

[0029] The left side of the top of the workbench 10 is connected to a connecting block 110, and the connecting block 110 is arranged perpendicular to the No. 1 groove 101. The right side of the connecting block 110 is laterally connected to a transverse rod 120, and the transverse rod 120 is located directly above the No. 1 groove 101, and the transverse rod 120 and the No. 1 groove 101 are parallel to each other. The transverse rod 120 is movably sleeved with a sealing block 130, and the sealing block 130 is 'T'-shaped. The sealing block 130 is movably arranged in the No. 1 groove 101, and an elastic member 140 is sleeved on the transverse rod 120, and the two ends of the elastic member 140 respectively contact the connecting block 110 and the sealing block 130; when the sealing block 130 is subjected to a thrust, the sealing block 130 moves to the left to retract the transverse rod 120 into the sealing block 130, and at the same time, the sealing block 130 squeezes the elastic member 140. When the thrust of the sealing block 130 is cancelled, the sealing block 130 moves back along the direction of the transverse rod 120 under the restoring force of the elastic member 140.

[0030] A second slot 102 and a third slot 103 are respectively provided on both sides of the first slot 101. An image acquisition sensor 20 is provided on the side of the workbench 10 close to the second slot 102. A plurality of light source generating devices 30 are provided in the third slot 103. The light emitted by the light source generating devices 30 is in the shape of intervals, and the light emitted by the light source generating devices 30 is accompanied by colors, such as red and green, which can improve the light recognition. The interval light sources emitted by the plurality of light source generating devices 30 are arranged to overlap with each other, such as Figure 6 As shown, the light emitted by the light source generating device 30 in slot No. 2 102 can be enhanced, making it easier for the image acquisition sensor 20 to collect and identify.

[0031] The image acquisition sensor 20 is connected to the processor to process and analyze whether there is light emitted by the light source generating device 30 in the image, so as to determine whether there is a defect in the scraper.

[0032] The side wall of the sealing block 130 in contact with the second groove 102 is elastic, which has a sealing effect, reduces the external natural light from entering the second groove 102, and keeps the second groove 102 in a dark environment, which is beneficial for the image acquisition sensor 20 to identify the light emitted by the light source generating device 30.

[0033] The top of the workbench 10 is connected to a mounting bracket 40, and a bolt 410 is threadedly sleeved on the mounting bracket 40, and a U-shaped part 420 is provided inside the mounting bracket 40, and the opening of the U-shaped part 420 is set downward, and a plurality of rolling shafts 430 are provided at the bottom opening of the U-shaped part 420, and the U-shaped part 420 is movably sleeved on the bottom of the bolt 410, so that the U-shaped part 420 will not rotate with the bolt 410, and the workbench 10 is located on both sides of the No. 1 groove 101 and is vertically connected with vertical rods 440, and the two sides of the U-shaped part 420 are movably sleeved on the vertical rods 440; by rotating the bolt 410, the bolt 410 pushes or pulls the vertical rod 440 to move up or down, thereby controlling the distance between the bottom of the rolling shaft 430 and the bottom of the inner cavity of the No. 1 groove 101, and the scraper is restricted by the rolling shaft 430. The scraper bottom is always in contact with the bottom of the inner cavity of the No. 1 groove 101.

[0034] The working principle and use process of the utility model are as follows: insert the scraper into the left side of the No. 1 groove 101, and the left side of the scraper contacts the right side of the sealing block 130. Then push the scraper into the No. 1 groove 101, and the scraper pushes the sealing block 130 to move left together. The sealing block 130 gradually passes through the opening of the No. 2 groove 102 and the light source generated by the light source generating device. When the image acquisition sensor 20 obtains the light source generated by the light source generating device, it is judged that the scraper is unqualified, otherwise it is qualified.

[0035] The scraper is released and moves out of the No. 1 groove 101 under the action of the elastic member 140 .

[0036] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
