Description

Technical Field

[0001] This utility model belongs to the field of paper cutting machine technology, specifically relating to a fully automatic self-inspection device for the height of the cutting blade tip. Background Technology

[0002] A paper cutter is an office device used to cut paper. It uses sharp blades or rollers in conjunction with precise guide rails to quickly and neatly cut paper to a set size. It is commonly found in printing plants, printing shops, and offices. There are various types, such as manual and electric, to meet different cutting needs.

[0003] If the cutting blade tip height of a paper cutter is inconsistent, the paper will be subjected to uneven force during cutting, which can easily result in uneven cuts and rough edges, affecting the cutting quality and accelerating blade wear, leading to equipment damage. Therefore, it is necessary to check this.

[0004] In existing technologies, the common method for detecting the cutting tip height of a paper cutter is to use a depth gauge or vernier caliper. When using a depth gauge, the base of the gauge is placed stably on the worktable, the measuring rod is pressed down so that the tip lightly touches the blade tip, and the reading is taken after locking it while maintaining verticality. Multiple measurements are taken and the average value is calculated. When using a vernier caliper to detect the depth of the blade cutting into the blade strip, the original thickness of the blade strip is measured first, and then the remaining height after cutting is measured. The difference between the two is the cutting depth. If the depth is not within the standard range or the distance from the blade tip to the worktable deviates from the standard, the blade tip height needs to be adjusted. Although the above methods can detect the cutting tip height of a paper cutter, they require the use of external tools and involve many steps, which consumes a lot of time and reduces work efficiency.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figure 1 - Figure 7 As shown, a fully automatic self-inspection device for cutting blade tip height includes a frame 1, which supports a fixed bracket 11 and a worktable 12.

[0020] A bracket 11 is connected to the top of the frame 1. The bracket 11 is used to help fix the cutting trolley 3.

[0021] A workbench 12 is connected to the middle of the frame 1. The workbench 12 is used to assist in fixing the first rotating rod 201 and the second rotating rod 27.

[0022] Two sets of symmetrically arranged cutting carriages 3 are set on one side of the bracket 11, corresponding to the position of the workbench 12. Each set of cutting carriages 3 has 3-5 carriages, and the cutting carriages 3 are used to carry the cutting blades.

[0023] A detection groove 31 is provided above the workbench 12 at the position corresponding to the lower end of the cutting carriage 3. The detection groove 31 is used to contact the lower end of the cutting carriage 3 and detect the distance the lower end of the cutting carriage 3 descends, thereby determining the height of the cutting blade tip.

[0024] In practical use, when the lower end of the cutting carriage 3 moves to the position corresponding to the detection groove 31, the voice coil motor inside the cutting carriage 3 drives the lower end of the cutting carriage 3 to descend, so that the lower end of the cutting carriage 3 contacts the detection groove 31. After contact, the lower end of the cutting carriage 3 can no longer descend. The processing unit determines the descent distance of the lower end of the cutting carriage 3, thereby determining the height of the cutting blade tip. This completes the detection of the cutting blade tip height and determines whether the height of the cutting blade needs to be adjusted. The operation is simple and convenient, achieving the purpose of automatically detecting the height of the cutting blade tip, reducing operation time, and improving work efficiency.

[0025] The bracket 11 is connected to the position of the cutting carriage 3 by symmetrically arranged slide rails 32, and the cutting carriage 3 is connected to the position of the slide rails 32 by symmetrically arranged sliders 33. The sliders 33 are slidably connected to the slide rails 32. Through the cooperation of the sliders 33 and the slide rails 32, the position of the cutting carriage 3 can be limited.

[0026] The bracket 11 is rotatably connected to four sets of symmetrically arranged third synchronous pulleys 4 at the position corresponding to the cutting trolley 3. Each set of third synchronous pulleys 4 has two symmetrically arranged pulleys, and the corresponding third synchronous pulleys 4 are meshed with a second synchronous belt 41. Through the cooperation of the second synchronous belt 41, the corresponding third synchronous pulleys 4 can rotate synchronously.

[0027] The cutting carriage 3 is connected to an external plate 42 on the side near the second synchronous belt 41. One set of external plates 42 is located between the two upper second synchronous belts 41, and the other set of external plates 42 is located between the two lower second synchronous belts 41. The end of each external plate 42 near the second synchronous belt 41 is connected to a fixing block 43. The fixing block 43 is connected to the corresponding second synchronous belt 41. With the cooperation of the second synchronous belt 41, the cutting carriage 3 can be driven to move when the third synchronous wheel 4 rotates.

[0028] A second motor 44 is connected to one end of the bracket 11 at the position corresponding to the third synchronous pulley 4. The second motor 44 passes through the bracket 11 and is connected to the fourth synchronous pulley 45. The second motor 44 is used to drive the fourth synchronous pulley 45 to rotate.

[0029] The third synchronous pulley 4 is connected to the fifth synchronous pulley 46 at the position corresponding to the fourth synchronous pulley 45. The third synchronous belt 47 meshes between the adjacent fourth synchronous pulley 45 and the fifth synchronous pulley 46. Through the cooperation of the fourth synchronous pulley 45, the fifth synchronous pulley 46 and the third synchronous belt 47, the third synchronous pulley 4 can be driven to rotate, thereby causing the second synchronous belt 41 to rotate.

[0030] In practical use, the second motor 44 is started to drive the fourth synchronous pulley 45 to rotate. The fourth synchronous pulley 45, together with the third synchronous belt 47, causes the fifth synchronous belt and the third synchronous pulley 4 to rotate. Correspondingly, the third synchronous pulley 4, together with the second synchronous belt 41, causes the third synchronous pulley 4 and the second synchronous belt 41 to rotate synchronously. The rotation of the second synchronous belt 41, together with the outer plate 42 and the fixing block 43, drives the cutting carriage 3 to move, so that the lower end of the cutting carriage 3 can correspond to the detection groove 31 after moving.

[0031] Three evenly arranged bearing frames 2 are connected to the lower surface of the workbench 12. Four first rotating rods 201 are connected between the bearing frames 2. The bearing frames 2 are used to support and fix the two ends and the middle of the first rotating rods 201, so that the first rotating rods 201 can be stabilized.

[0032] One end of the first rotating rod 201 passes through the frame 1 and is connected to the first synchronous pulley 21. Inside the frame 1, at a position corresponding to the lower part of the workbench 12, a first motor 22 is connected. The output end of the first motor 22 passes through the frame 1 and is connected to the second synchronous pulley 23. A tensioning pulley 24 is provided between the first synchronous pulley 21 and the second synchronous pulley 23, and the tensioning pulley 24 is rotatably connected to the frame 1. The outer sides of the first synchronous pulley 21, the second synchronous pulley 23, and the tensioning pulley 24 are all meshed with a first synchronous belt 25. The first motor 22 is used to drive the second tensioning pulley 24 to rotate, and the tensioning pulley 24 is used to tension the first synchronous belt 25. The first synchronous belt 25 cooperates with the first synchronous pulley 21 and the second synchronous pulley 23 to enable the four first rotating rods 201 to rotate synchronously.

[0033] Two sets of symmetrically arranged fixed seats 26 are connected to the upper surface of the workbench 12 corresponding to the position of the first rotating rod 201. The fixed seats 26 are used to fix the position of the second rotating rod 27.

[0034] Each of the fixed bases 26 has a symmetrically arranged fixing groove 261 on its upper part, which is used to place the second rotating rod 27.

[0035] The ends of the second rotating rod 27 are all connected to bearings, and the bearings are located in the fixing groove 261. The bearings are used to reduce the friction between the second rotating rod 27 and the fixing seat 26.

[0036] Each fixed base 26 is connected to a pressure plate 28 via a screw, and the pressure plate 28 is used to press the second rotating rod 27.

[0037] A limit frame 29 is connected to the upper surface of the fixed base 26 at the position corresponding to the pressure plate 28. The pressure plate 28 is slidably connected to the limit frame 29. The limit frame 29 is used to limit the installation position of the pressure plate 28 to ensure that the end of the pressure plate 28 corresponds to the second rotating rod 27.

[0038] Multiple evenly arranged first synchronization blocks 202 are connected to the outer side of the first rotating rod 201, and multiple evenly arranged second synchronization blocks 271 are connected to the outer side of the second rotating rod 27. The first synchronization blocks 202 and the second synchronization blocks 271 mesh with each other, and through the cooperation of the first synchronization blocks 202 and the second synchronization blocks 271, the first rotating rod 201 and the second rotating rod 27 can rotate synchronously.

[0039] In practical use, the first motor 22 drives the second synchronous pulley 23 to rotate. The second synchronous pulley 23, together with the first synchronous belt 25 and the tensioning pulley 24, makes the four first synchronous pulleys 21 rotate synchronously. The rotation of the first synchronous pulleys 21 drives the first rotating rod 201 to rotate. The first rotating rod 201, with the cooperation of the first synchronous block 202 and the second synchronous block 271, drives the second rotating rod 27 to rotate. After the second rotating rod 27 rotates, the paper can be fed. The first rotating rod 201 can be replaced by removing the pressure plate 28.
