Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, and particularly relates to a die-cutting tool holder of a die-cutting machine. Background Technique

[0002] Traditional die-cutting refers to a cutting process for post-processing of printed matter. The die-cutting process can cut printed matter or other paper products into die-cutting plates according to pre-designed graphics, so that the shape of the printed matter is no longer limited to straight edges and right angles. In traditional die-cutting production, die-cutting knives are combined into a die-cutting plate according to the patterns required by product design. Under the action of pressure, the printed matter or other sheet blanks are rolled and cut into the required shapes or cut marks. The indentation process is to use a scoring knife or a scoring die to press out score lines on the sheet material under the action of pressure, or use a wire rolling wheel to roll out score lines on the sheet material, so that the sheet material can be bent and formed at a predetermined position. Usually, the die-cutting and indentation process is to combine the die-cutting knife and the scoring knife in the same template and perform die-cutting and indentation processing on the die-cutting machine at the same time, which is simply called die-cutting and pressing.

[0003] The traditional die-cutting machine tool holder is difficult to adapt to tapes or paper tapes of different thicknesses. When it is necessary to adjust the gap between the pressure roller and the roller knife, the traditional adjustment method is more complicated to operate. Most of them are to replace the pressure rollers with different cross-sectional diameters to change the gap between the pressure roller and the roller knife. Therefore, a round die-cutting machine tool holder device with simple operation and strong adaptability is needed.

[0004] Therefore, we propose a die-cutting tool holder of a die-cutting machine. Content of the Utility Model

[0005] The purpose of the utility model is to provide a die-cutting tool holder of a die-cutting machine to solve the problems raised in the above background technique.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a die-cutting knife seat of a die-cutting machine, comprising a knife seat, a roller knife is rotatably connected to the middle part of the knife seat, a driving motor is fixedly installed on the bottom of the knife seat, a sliding groove is opened on the knife seat above the roller knife, a threaded rod is rotatably connected to the top of the knife seat, a fixed seat is fixedly installed in the middle part of one side of the knife seat, a sliding block is slidably connected to the inside of the sliding groove, a pressure roller located above the roller knife is rotatably connected to the middle part of the sliding block, the bottom of the threaded rod is rotatably connected to the top of the sliding block, and a knob is fixedly installed on the top of the threaded rod. One end of the roller cutter is transmission connected to the output end of the driving motor, and the other end of the roller cutter is fixedly installed with a third synchronous wheel, and one end of the pressure roller is fixedly installed with a fourth synchronous wheel, and the third synchronous wheel is transmission connected to the fourth synchronous wheel through the second synchronous belt, and the top of the fixed seat is integrally connected with a mounting seat, and one end of the fixed seat close to the third synchronous wheel is rotatably connected to a swing rod, and the other end of the swing rod is rotatably connected to a clamping wheel, and the clamping wheel is in tight and rolling contact with the middle part of the second synchronous belt, and a clamping spring is fixedly installed on the mounting seat, and the other end of the clamping spring is fixedly installed to the middle part of the swing rod.

[0007] Optionally, a first synchronous wheel is fixedly mounted on the output end of the driving motor, a second synchronous wheel is fixedly mounted on one end of the roller cutter, and the first synchronous wheel is transmission-connected to the second synchronous wheel via a first synchronous belt.

[0008] Optionally, a diameter of the abutting wheel is smaller than a minimum distance between the third synchronizing wheel and the fourth synchronizing wheel.

[0009] Optionally, the axes of the pressure roller and the roller cutter are located in the same vertical plane.

[0010] Optionally, the diameters of the third synchronization wheel and the fourth synchronization wheel are the same.

[0011] Optionally, the length of the threaded rod is greater than the length of the sliding groove, and the length of the sliding block is less than the diameter of the pressure roller.

[0012] Optionally, a connecting disc is fixedly mounted on the middle portion of the swing arm, and the retaining spring is fixedly mounted on the swing arm via the connecting disc.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The die-cutting knife seat of the die-cutting machine is provided with a threaded rod and a sliding groove. When the gap between the pressure roller and the roller knife needs to be adjusted, the knob is turned to rotate the threaded rod and then drive the sliding block to slide inside the sliding groove, so that the distance between the pressure roller and the roller knife can be adjusted to adapt to tapes or paper tapes of different thicknesses. The operation is simple and the adaptability is strong.

[0015] 2. For the die-cutting tool holder of this die-cutting machine, by setting the pressing wheel, when adjusting the distance between the pressure roller and the roller cutter by turning the knob, as the sliding block moves, the distance between the third synchronous pulley and the fourth synchronous pulley will also change. When the distance between the third synchronous pulley and the fourth synchronous pulley becomes smaller, the second synchronous belt becomes loose, and the pressing spring pushes the swing rod to rotate, so that the pressing wheel presses the second synchronous belt tightly. When the distance between the third synchronous pulley and the fourth synchronous pulley becomes larger, the second synchronous belt is tightened, and the second synchronous belt drives the swing rod to rotate and squeezes the spring, so that the transmission of the second synchronous belt is not affected.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 4, the present utility model provides a die-cutting tool holder for a die-cutting machine, including a tool holder 1. A roller cutter 2 is rotatably connected to the middle of the tool holder 1. A driving motor 8 is fixedly installed at the bottom of the tool holder 1. The tool holder 1 is provided with a sliding groove 3 above the roller cutter 2. A threaded rod 5 is rotatably connected through the top of the tool holder 1. A fixed seat 15 is fixedly installed in the middle of one side of the tool holder 1. A sliding block 4 is slidably connected inside the sliding groove 3. A pressure roller 6 above the roller cutter 2 is rotatably connected to the middle of the sliding block 4. The axes of the pressure roller 6 and the roller cutter 2 are located in the same vertical plane. The bottom of the threaded rod 5 is rotatably connected to the top of the sliding block 4. A knob 7 is fixedly installed at the top of the threaded rod 5. The length of the threaded rod 5 is greater than the length of the sliding groove 3. The length of the sliding block 4 is less than the diameter of the pressure roller 6. One end of the roller cutter 2 is in transmission connection with the output end of the driving motor 8. A first synchronous pulley 9 is fixedly installed at the output end of the driving motor 8. A second synchronous pulley 11 is fixedly installed at one end of the roller cutter 2. The first synchronous pulley 9 is in transmission connection with the second synchronous pulley 11 through a first synchronous belt 10. A third synchronous pulley 12 is fixedly installed at the other end of the roller cutter 2. A fourth synchronous pulley 13 is fixedly installed at one end of the pressure roller 6. The third synchronous pulley 12 is in transmission connection with the fourth synchronous pulley 13 through a second synchronous belt 14. The diameters of the third synchronous pulley 12 and the fourth synchronous pulley 13 are the same. By setting the threaded rod 5 and the sliding groove 3, when it is necessary to adjust the gap between the pressure roller 6 and the roller cutter 2, turn the knob 7, so that the threaded rod 5 rotates to drive the sliding block 4 to slide inside the sliding groove 3, so that the distance between the pressure roller 6 and the roller cutter 2 can be adjusted to adapt to tapes or paper tapes of different thicknesses. The operation is simple and the adaptability is strong. The top of the fixed seat 15 is integrally connected with a mounting seat 16. One end of the fixed seat 15 close to the third synchronous pulley 12 is rotatably connected with a swing rod 18. The other end of the swing rod 18 is rotatably connected with a pressing wheel 19. The pressing wheel 19 is in rolling contact with the middle of the second synchronous belt 14 in a pressing manner. The diameter of the pressing wheel 19 is less than the minimum distance between the third synchronous pulley 12 and the fourth synchronous pulley 13. A pressing spring 17 is fixedly installed on the mounting seat 16. The other end of the pressing spring 17 is fixedly installed with the middle of the swing rod 18. A connecting disc is fixedly installed at the middle of the swing rod 18. The pressing spring 17 is fixedly installed with the swing rod 18 through the connecting disc. By setting the pressing wheel 19, when turning the knob 7 to adjust the distance between the pressure roller 6 and the roller cutter 2, as the sliding block 4 moves, the distance between the third synchronous pulley 12 and the fourth synchronous pulley 13 will also change. When the distance between the third synchronous pulley 12 and the fourth synchronous pulley 13 becomes smaller, the second synchronous belt 14 becomes loose, and the pressing spring 17 pushes the swing rod 18 to rotate, so that the pressing wheel 19 presses the second synchronous belt 14 tightly. When the distance between the third synchronous pulley 12 and the fourth synchronous pulley 13 becomes larger, the second synchronous belt 14 is tightened, and the second synchronous belt 14 drives the swing rod 18 to rotate and squeezes the spring, so that the transmission of the second synchronous belt 14 is not affected.

[0023] Working principle:

[0024] When it is necessary to adjust the gap between the pressure roller 6 and the roller cutter 2, turn the knob 7, so that the threaded rod 5 rotates and drives the sliding block 4 to slide inside the sliding groove 3, so that the distance between the pressure roller 6 and the roller cutter 2 can be adjusted to adapt to tapes or paper tapes of different thicknesses. When turning the knob 7 to adjust the distance between the pressure roller 6 and the roller cutter 2, as the sliding block 4 moves, the distance between the third synchronous pulley 12 and the fourth synchronous pulley 13 will also change. When the distance between the third synchronous pulley 12 and the fourth synchronous pulley 13 becomes smaller, the second synchronous belt 14 becomes slack, and the tightening spring 17 pushes the swing rod 18 to rotate, so that the tightening wheel 19 presses the second synchronous belt 14 tightly. When the distance between the third synchronous pulley 12 and the fourth synchronous pulley 13 becomes larger, the second synchronous belt 14 is tightened, and the second synchronous belt 14 drives the swing rod 18 to rotate and compresses the spring, so that the transmission of the second synchronous belt 14 is not affected.
