Description

Technical Field

[0001] This utility model relates to the field of printing press blade holder technology, and in particular to a grating digital display blade holder that is easy to maintain. Background Technology

[0002] The doctor blade of a printing press is mainly used to precisely control ink transfer and ensure printing quality. The doctor blade removes excess ink from non-printing areas by physically contacting the surface of the printing plate or anilox roller, ensuring that the ink in the printing area is evenly transferred to the substrate. However, when cleaning the doctor blade holder of a current printing press, the entire holder and doctor blade need to be removed, cleaned, and then reinstalled, which is very inconvenient.

[0003] For example, Chinese utility model patent CN209600054U discloses a printing press doctor blade device, including a printing press doctor blade holder and a printing press doctor blade body. Although this solution improves the strength of the printing press doctor blade body and effectively prevents the doctor blade from sticking together when producing multiple rolls of products, the doctor blade holder is generally grooved, making it difficult to clean its interior. In addition, multiple fixing studs are installed on the side, making it very inconvenient to disassemble them one by one. Based on this, a grating digital display doctor blade holder that can solve the above problems and is easy to maintain is proposed. Utility Model Content

[0004] To solve the technical problem of cleaning the blade holder of a printing press, this utility model provides a grating digital display blade holder that is easy to maintain.

[0005] This utility model is achieved by the following technical solution: a grating digital display scraper holder that is easy to maintain, including a scraper, a back plate fixedly connected to one side of the scraper, clamps rotatably connected to both sides of one end of the back plate, a limit rod fixedly connected between the two clamps, a support and fixing mechanism provided on one side of the back plate, and a buckling mechanism provided on the side of the two clamps away from the limit rod.

[0006] As a further improvement to the above solution, the support and fixing mechanism includes a clamping block fixedly connected to the side of the blade back plate away from the scraper, the clamping block being slidably connected between the two clamping plates, and a load-bearing plate mechanism being provided on the side of the two clamping blocks away from the blade back plate.

[0007] As a further improvement to the above solution, the load-bearing plate mechanism includes a baffle that abuts against one side of the two clamping blocks. A plurality of positioning bolts are rotatably connected to the baffle, and each positioning bolt is threadedly connected to the clamping block.

[0008] As a further improvement to the above solution, the buckling mechanism includes a clamp fixedly connected to the side of the clamp block away from the limiting rod, and a caliper mechanism that cooperates with the clamp to fix the two clamps is provided between them.

[0009] As a further improvement to the above solution, the caliper mechanism includes a limiting platform fixedly connected between the two clamping blocks. The limiting platform is provided with a hollow groove and a sliding groove. The lower edge of the hollow groove intersects with the upper edge of the sliding groove. A spring is movably connected inside the hollow groove. A push handle is provided below the spring. The push handle is rotatably connected to the two clamping plates. A locking mouth is fixedly connected to one end of the push handle. The locking mouth cooperates with the clamp.

[0010] As a further improvement to the above solution, a positioning groove is provided on the clamping block, and the positioning groove is configured to cooperate with the limiting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a clamping mechanism. When it is necessary to clean the scraper or the space between the two clamps, simply push the handle upward to easily release the scraper and the back plate. After release, the space between the two clamps is opened, making it easier for workers to clean. It is simple to operate and easy to maintain.

[0013] 2. When the tool needs to be replaced, the tool can be opened by first opening the caliper mechanism, then turning the back plate to one side to make room, and then turning the positioning bolt to release the scraper. After replacing the new tool, it can be pushed back between the two clamps, thus achieving the effect of quick insertion and release of the scraper, which is convenient for later maintenance.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example:

[0023] Please combine Figures 1-5 This embodiment provides a grating digital display scraper holder that is easy to maintain. It includes a scraper 1, a back plate 7 fixedly connected to one side of the scraper 1, and clamping plates 2 rotatably connected to both sides of one end of the back plate 7. It should be noted that the two clamping plates 2 are fixedly connected by multiple detachable bolts, and the distance between them is adapted to the thickness of the clamping block 9. A limiting rod 3 is fixedly connected between the two clamping plates 2. The limiting rod 3 plays a further positioning role and prevents the back plate 7 from shifting due to long-term wear. A support and fixing mechanism is provided on one side of the back plate 7, and a buckling mechanism is provided on the side of the two clamping plates 2 away from the limiting rod 3.

[0024] Please combine Figure 3 As shown, the support and fixing mechanism includes a clamping block 9 fixedly connected to the side of the blade back plate 7 away from the scraper 1. The scraper 1, the clamping block 9, and the blade back plate 7 can be designed as an integrated structure or as an assembly, depending on the scenario. The clamping block 9 is slidably connected between the two clamping plates 2, and a load-bearing plate mechanism is provided on the side of the two clamping blocks 9 away from the blade back plate 7.

[0025] Please combine Figure 2 As shown, the load-bearing plate mechanism includes a baffle 5 that abuts against one side of the two clamping blocks 9. The baffle 5 provides support, making the scraper 1 fixed to one side of the blade back plate 7 more stable, and at the same time increasing the shear resistance of the entire device. Two positioning bolts 4 are rotatably connected to the baffle 5, and each positioning bolt 4 is threadedly connected to the clamping block 9.

[0026] Please combine Figure 3 As shown, the buckling mechanism includes a clamp 11 fixedly connected to the side of the clamping block 9 away from the limiting rod 3. The clamp 11 has an arc-shaped protrusion. A clamping mechanism that cooperates with the clamp 11 to fix the clamp is provided between the two clamping plates 2.

[0027] Please combine Figure 3As shown, the caliper mechanism includes a limiting platform 12 fixedly connected between two clamping blocks 9. The limiting platform 12 is detachable and has a hollow groove 13 and a sliding groove 15 respectively. The hollow groove 13 has a cylindrical space inside for placing a spring 14. The lower edge of the hollow groove 13 intersects with the upper edge of the sliding groove 15. The spring 14 is movably connected inside the hollow groove 13, and a push handle 6 is provided below the spring 14. Please refer to... Figure 5 As shown, after one end of the push handle 6 is rotated, it can touch the lower side of the spring 14 through the groove 15. The push handle 6 is rotatably connected to the two clamps 2. One end of the push handle 6 is fixedly connected to the latch 8, which is set to cooperate with the clamp 11.

[0028] Please combine Figure 3 As shown, a positioning groove 10 is provided on the clamping block 9, and the positioning groove 10 is configured to cooperate with the limiting rod 3.

[0029] The implementation principle of the easy-to-maintain grating digital display scraper holder in this application embodiment is as follows: When it is necessary to replace the scraper 1 or to perform rust prevention treatment on the position between the two clamping plates 2, first rotate the positioning bolt 14, first remove the baffle 5 from one side of the clamping plate 2, and then press the push handle 6. Through the lever torque amplification effect, the spring 14 deforms and compresses, pushing the chuck 8 and the clamp 11 to disengage from the clamp. After release, rotate the blade back plate 7 to one side, and rotate the scraper 1 to one side to a place with operating space, and then replace the scraper 1, or clean the ink between the scraper 1 and the clamping plate 2.
