Description

Technical Field

[0001] This utility model relates to the technical field of cutting tool calibration tools, and more specifically, to a cutting tool calibration tool for printing press die-cutting plates. Background Technology

[0002] In the cardboard box production process, the die-cutting blade of the printing machine in the cardboard box workshop is embedded in a cylindrical wooden template. During production, the direction of the blade is prone to deviation, resulting in defective products. Because the die-cutting plate is curved and the blade is embedded in the wooden template, it is difficult to correct the curved blade.

[0003] Currently, employees generally use hammering to calibrate the cutter, but hammering is ineffective, inefficient, and can easily damage the cutter, creating potential quality issues.

[0004] A search revealed that Chinese patent CN204196329U discloses a die-cutting plate correction tool for printing presses. The lower part of this structure is semi-cylindrical with an internal groove for the cutter. In use, the cutter to be adjusted is placed in the groove, and the tool is rotated to correct the cutter's deformation based on its deviation direction. The semi-cylindrical design facilitates up-and-down rotation when the tool is holding the cutter in place, and the handle allows for easy control of rotation. This tool is convenient to use; simply place the cutter into the groove for adjustment. In actual production, it can promptly prevent defective products caused by die-cutting plate problems, significantly improve production efficiency, reduce the labor intensity of employees, and effectively eliminate potential quality issues. Its simple and practical structure and operation bring numerous positive benefits to production.

[0005] However, in actual use, different batches of cutters may have dimensional tolerances in actual production. The groove size in the device is fixed. When the gap between the groove and the cutter is too large, the cutter may wobble in the groove when the tool is rotated to correct the cutter, resulting in inaccurate correction. If the gap is too small, the cutter may be difficult to put into the groove, or the cutter may be damaged during the insertion process, thus affecting the performance. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a printing press die-cutting blade correction tool to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A die-cutting tool for a printing press includes a fixing block, the surface of which has a groove, and an adjustment mechanism is provided inside the groove;

[0009] The adjustment mechanism includes a guide groove inside the fixed block, a T-shaped guide block slidably disposed inside the guide groove, a clamping plate fixedly disposed on one side of the T-shaped guide block, a threaded rod rotatably disposed on the top of the clamping plate, one end of the threaded rod passing through the fixed block and extending outward from the fixed block, a turntable fixedly disposed on one end of the threaded rod, the threaded rod being threadedly connected to the fixed block, a rubber layer fixedly disposed on the inner wall of the fixed block and one side of the clamping plate, a connecting block fixedly disposed on one side of the fixed block, the connecting block having a T-shaped cross-section, and a connecting frame sleeved on the outside of the connecting block.

[0010] By adopting the above technical solution, the clamping force of the cutter can be flexibly adjusted, the rubber layer can increase friction and protect the cutter, and can effectively achieve stable clamping and correction of cutters of different sizes, improving correction efficiency and accuracy.

[0011] As a further description of the above technical solution: A disassembly mechanism is provided on one side of the connecting frame.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The embodiments disclosed in this application are as follows: Figure 1-6 The printing press die-cutting blade correction tool shown includes a fixing block 1, a groove 2 is provided on the surface of the fixing block 1, and an adjustment mechanism is provided inside the groove 2;

[0027] The adjustment mechanism includes a guide groove 3 inside the fixed block 1, a T-shaped guide block 4 slidably disposed inside the guide groove 3, a clamping plate 5 fixedly disposed on one side of the T-shaped guide block 4, a threaded rod 6 rotatably disposed on the top of the clamping plate 5, one end of the threaded rod 6 passing through the fixed block 1 and extending outward from the fixed block 1, a turntable 7 fixedly disposed on one end of the threaded rod 6, and the threaded rod 6 being threadedly connected to the fixed block 1. A rubber layer 8 is fixedly disposed on the inner wall of the fixed block 1 and one side of the clamping plate 5. A connecting block 9 is fixedly disposed on one side of the fixed block 1, the connecting block 9 having a T-shaped cross-section, and a connecting frame 10 sleeved on the outside of the connecting block 9. The cutter is placed... Place the screw rod 6 in the groove 2 on the surface of the fixed block 1, and then rotate the screw rod 6. Since the screw rod 6 is threadedly connected to the fixed block 1, the rotation will cause the screw rod 6 to move axially. The T-shaped guide block 4 fixed at one end of the screw rod 6 slides in the guide groove 3. As the screw rod 6 moves axially, the T-shaped guide block 4 will push the clamping plate 5 to move along the direction of the guide groove 3. The clamping plate 5 moves closer and closer to the cutter until the rubber layer 8 on the inner wall of the fixed block 1 and one side of the clamping plate 5 comes into close contact with the cutter, firmly clamping the cutter in the groove 2. The rubber layer 8 can increase the friction, prevent the cutter from sliding during the correction process, and protect the cutter from being pinched.

[0028] Reference Figure 2-4As shown, a disassembly mechanism is provided on one side of the connecting frame 10. The disassembly mechanism includes two U-shaped frames 11 fixedly installed on the top of the connecting frame 10. U-shaped strips 12 are inserted into the interior of each of the two U-shaped frames 11. Mounting grooves 13 are formed on the surface of each U-shaped strip 12. A U-shaped fixing frame 14 is fixedly installed on the top of each U-shaped strip 12. A sliding plate 15 is slidably installed inside the U-shaped fixing frame 14 and is slidably connected to the mounting grooves 13. Two springs 16 are fixedly installed on the top of the sliding plate 15. One end of each spring 16 is connected to the inner wall of the U-shaped fixing frame 14. Two through holes are formed on the surface of the sliding plate 15. A locking rod 17 is fixedly installed inside each of the two through holes. The springs 16 are sleeved on the outside of the locking rods 17. One end of the locking rod 17 passes through the U-shaped fixing frame 14 and extends outward from the U-shaped fixing frame 14. A pull handle 18 is fixedly installed on one end of the locking rod 17. One end of the U-shaped strip 12 extends outward from the U-shaped strip 12. Two locking holes 19 are opened on the surface of the U-shaped strip 12. The two locking holes 19 are inserted into the locking rod 17 to connect the fixing block 1 and the connecting frame 10. First, the connecting block 9 with the cross-section of T is inserted into the connecting frame 10 so that the connecting block 9 and the connecting frame 10 are engaged. Then, the handle 18 is pulled upward. The handle 18 drives the locking rod 17 to move upward. The locking rod 17 compresses the spring 16, so that the other end of the locking rod 17 is pulled out from the locking hole 19 of the U-shaped strip 12. Then, the U-shaped strip 12 is inserted into the U-shaped frame 11. Then, the handle 18 is released. Under the elastic force of the spring 16, the locking rod 17 moves downward. The other end of the locking rod 17 is inserted into the locking hole 19 of the U-shaped strip 12, thereby fixing the U-shaped strip 12 in the U-shaped frame 11, realizing the fixed connection between the connecting block 9 and the connecting frame 10, thus facilitating the disassembly and replacement of the fixing block 1.

[0029] Reference Figure 5-6 As shown, a fixing post 20 is fixedly installed on one side of the connecting frame 10, and a handle 21 is fixedly installed on one side of the fixing post 20. A threaded sleeve 22 is fixedly installed on the surface of the handle 21. A threaded extension rod 23 is threadedly connected inside the threaded sleeve 22. A grip 24 is fixedly installed on one side of the threaded extension rod 23. Anti-slip sleeves 25 are fixedly installed on the outside of both the grip 24 and the handle 21. If the handle 21 is not long enough, the threaded extension rod 23 can be screwed into the threaded sleeve 22 to increase the operating length. Then, hold the grip 24 and apply the corresponding force to the tool through the handle 21 or the grip 24 according to the deviation direction of the cutter, so that the tool drives the cutter to deform, thereby realizing the correction of the cutter. Then, rotate the threaded rod 6 in the opposite direction to move the clamping plate 5 away from the cutter. When the pressure between the clamping plate 5 and the cutter is eliminated, the cutter can be taken out from the groove 2, completing the entire correction operation process.

[0030] Working principle of this utility model:

[0031] This utility model is a tool for correcting the die-cutting blade of a printing press. When using this device, the fixing block 1 is connected to the connecting frame 10. First, the connecting block 9 with a T-shaped cross-section is inserted into the connecting frame 10 to make the connecting block 9 cooperate with the connecting frame 10. Then, the handle 18 is pulled upward, and the handle 18 drives the locking rod 17 to move upward. The locking rod 17 compresses the spring 16, so that the other end of the locking rod 17 is pulled out from the locking hole 19 of the U-shaped strip 12. Then, the U-shaped strip 12 is inserted into the U-shaped frame 11. Then, the handle 18 is released. Under the elastic force of the spring 16, the locking rod 17 moves downward and the other end of the locking rod 17 is inserted into the locking hole 19 of the U-shaped strip 12, thereby fixing the U-shaped strip 12 in the U-shaped frame 11, realizing the fixed connection between the connecting block 9 and the connecting frame 10, thus facilitating the disassembly and replacement of the fixing block 1.

[0032] Place the cutter in the groove 2 on the surface of the fixing block 1, then rotate the turntable 7. The turntable 7 drives the threaded rod 6 to rotate. Since the threaded rod 6 is threadedly connected to the fixing block 1, the rotation will cause the threaded rod 6 to move axially. The T-shaped guide block 4 fixed at one end of the threaded rod 6 slides in the guide groove 3. As the threaded rod 6 moves axially, the T-shaped guide block 4 will push the clamping plate 5 to move along the direction of the guide groove 3. The clamping plate 5 moves closer and closer to the cutter until the rubber layer 8 on the inner wall of the fixing block 1 and one side of the clamping plate 5 is in close contact with the cutter, firmly clamping the cutter in the groove 2. The rubber layer 8 can increase the friction and prevent the cutter from sliding during the correction process, while protecting the cutter from being pinched.

[0033] Hold the handle 21. If the handle 21 is not long enough, screw the threaded extension rod 23 into the threaded sleeve 22 to increase the operating length. Then hold the grip 24 and apply the corresponding force to the tool through the handle 21 or grip 24 according to the direction of the cutter's deviation. This will cause the tool to deform the cutter, thereby correcting the cutter. Then rotate the threaded rod 6 in the opposite direction to move the clamping plate 5 away from the cutter. Once the pressure between the clamping plate 5 and the cutter is eliminated, the cutter can be removed from the groove 2, completing the entire correction operation.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
