Description

Technical Field

[0001] This application relates to the field of die-cutting tool testing technology, and in particular to a die-cutting roller blade edge angle measuring instrument. Background Technology

[0002] Die-cutting tools, also known as creasing knives, are cutting tools used to cut specific sheets of material in one go. Depending on their function, die-cutting tools can be divided into flat die-cutting tools, rotary die-cutting tools, etc. Among them, rotary die-cutting tools are also called die-cutting roller knives.

[0003] A die-cutting roller, as shown in the figure Figure 1 It includes a rotating roller 1 and a blade 2 disposed on the outer peripheral wall of the rotating roller 1 along the circumference of the rotating roller 1; the cross-section of the blade 2 is triangular, and the angle of the inner angle of the end of the triangle away from the rotating roller 1 is the blade angle.

[0004] Regarding the aforementioned technologies, in order to ensure the structural strength and sharpness of the die-cutting roller blade, the blade angle needs to be precisely designed. However, currently there is no dedicated testing device in the industry for detecting the blade angle of the die-cutting roller blade, which easily leads to a large difference between the actual value and the design value of the blade angle, resulting in poor processing accuracy of the die-cutting roller blade. Therefore, this needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide a die-cutting roller blade angle measuring instrument for detecting the die-cutting roller blade angle during die-cutting roller blade processing, so as to adjust the processing amount according to the detected value, thereby reducing the difference between the actual value and the design value of the die-cutting roller blade angle, which is beneficial to improving the processing accuracy of the die-cutting roller blade.

[0006] The die-cutting roller blade edge angle measuring instrument provided in this application adopts the following technical solution: A die-cutting roller blade edge angle measuring instrument includes a mounting rod and two support frames disposed on the mounting rod. A sliding seat is disposed on the mounting rod between the two support frames. The sliding seat is provided with an angle detection component for detecting the edge angle of the die-cutting roller blade. The angle detection component includes a main scale connected to the sliding seat, a secondary scale rotatably connected to the main scale, and an angle display component for displaying the included angle between the secondary scale and the main scale. The sidewalls of the secondary scale on both sides along the length direction of the mounting rod are designed to fit against the sidewalls of the die-cutting roller blade edge. The sliding seat is slidably connected to the mounting rod along the length direction of the mounting rod.

[0007] By adopting the above technical solution, during testing, a support frame with mounting rods is placed above the rotating roller of the die-cutting cutter. The sliding seat is then slid to move the vernier scale close to the position to be measured near the die-cutting cutter edge. The vernier scale is then rotated and the sliding seat is moved so that the side wall of the vernier scale is in contact with the side wall of one side of the measured position of the cutter edge. Finally, the angle value displayed on the angle display is read to obtain the tilt angle of the corresponding side of the measured cutter edge. Similarly, the tilt angle of the other side of the measured position of the cutter edge can be measured to calculate the angle of the cutter edge. During cutter edge processing, the angle of the die-cutting cutter edge can be detected at any time to adjust the processing amount based on the detected value, thereby reducing the difference between the actual value and the design value of the die-cutting cutter edge angle. This helps to improve the processing accuracy of the die-cutting cutter edge and increase the yield rate.

[0008] Optionally, the support frame includes a mounting base and a support block connected to the mounting base. The support block is provided with a clearance groove for mounting on the outer peripheral wall of the die-cutting roller. The mounting base is slidably connected to the mounting rod along the length direction of the mounting rod, and the mounting base is provided with a fixing member for fixing the mounting base.

[0009] By adopting the above technical solution, the rotating roller of the die-cutting cutter can be relatively embedded in the relief groove to improve the stability of the support block relative to the rotating roller of the die-cutting cutter. The sliding seat is used to adjust the position of the support block so that it can be mounted on the outer peripheral wall of the rotating roller of the die-cutting cutter, thereby positioning the mounting rod above the rotating roller of the die-cutting cutter. This operation is simple and convenient.

[0010] Optionally, a connecting assembly is provided between the mounting base and the mounting rod, and the mounting base is connected to the mounting rod through the connecting assembly; the mounting rod is provided with a sliding groove along its own length direction, and the connecting assembly includes a connecting base, a support wheel, and two abutting wheels, both of which are rotatably connected to the connecting base; the peripheral wall of the support wheel abuts against the inner wall of one side of the sliding groove along its own width direction, and the peripheral wall of the abutting wheel abuts against the inner wall of the other side of the sliding groove, with the support wheel located between the two abutting wheels; the mounting base is connected to the connecting base.

[0011] By adopting the above technical solution, the support wheel and the two abutment wheels cooperate with each other to allow the connecting seat to slide relative to the mounting rod, which helps to reduce the friction between the connecting seat and the mounting rod, and at the same time reduces the possibility of the connecting seat rotating around the axis of the support wheel.

[0012] Optionally, the inner walls of both sides of the sliding groove along its width direction are provided with limit strips, and the peripheral walls of the support wheel and the abutment wheel are respectively provided with limit ring grooves along their circumference to engage with the corresponding limit strips.

[0013] By adopting the above technical solution, the limiting ring groove and the limiting strip are engaged, which helps to limit the movement of the connecting seat along the depth direction of the sliding groove, thereby reducing the possibility of the connecting seat and the mounting rod separating, and facilitating the sliding of the connecting seat and the mounting seat.

[0014] Optionally, the support frame further includes an adjusting component, and the support block is connected to the mounting base via the adjusting component; the adjusting component includes an adjusting bolt and an elastic element; the mounting base has a mounting hole extending through the width direction of the mounting rod, and the shank of the adjusting bolt is inserted through the mounting hole; the support block has an adjusting screw hole that engages with the threaded adjusting bolt; one end of the elastic element is connected to the mounting base, and the other end is connected to the support block, and the elastic element is used to drive the support block to move away from the mounting rod.

[0015] By adopting the above technical solution, when the adjusting bolt is rotated, the elastic element restricts the rotation of the support block, allowing the adjusting bolt to rotate relative to the support block, thus enabling the adjusting bolt to move axially relative to the support block. When the adjusting bolt moves relative to the support block, the elastic element drives the support block to move away from the mounting rod, allowing the head of the adjusting bolt to abut against the mounting seat, thereby adjusting the distance between the mounting rod and the die-cutting roller. This allows the side wall of the auxiliary ruler to fit against the side wall of the die-cutting roller's blade, while simultaneously ensuring that the main ruler and the die-cutting roller are parallel, thus improving detection accuracy. The adjusting bolt and the elastic element work together to easily adjust the positions of the main and auxiliary rulers according to the height of the blade, resulting in a simple structure and convenient operation.

[0016] Optionally, the sliding seat is provided with a distance detection element for detecting the distance between itself and the outer peripheral wall of the die-cutting roller.

[0017] By adopting the above technical solution, after the mounting rod is erected, the sliding seat is slidable to allow the distance detection component to detect the distance between the main ruler and the outer peripheral wall of the die-cutting roller. The distance between one of the support blocks and the mounting rod can be adjusted according to the detection of the distance detection component to make the distance between the main ruler and the outer peripheral wall of the die-cutting roller equal. This makes the main ruler and the die-cutting roller parallel, which helps to improve the parallelism between the main ruler and the die-cutting roller, thereby improving the angle detection accuracy. The operation is simple and convenient.

[0018] Optionally, a rotating seat is provided between the main scale and the sliding seat, and the main scale is connected to the sliding seat through the rotating seat; the rotating seat is provided with a rotating shaft that is rotatably connected to the sliding seat, and the main scale is connected to the rotating seat; the axial direction of the rotating shaft is arranged along the depth direction of the relief groove.

[0019] By adopting the above technical solution, rotating the rotating seat can drive the main ruler to rotate synchronously; when the blade to be measured is spirally bent along the outer peripheral wall of the die-cutting roller, the rotating seat can be rotated and the support block can be moved along the peripheral wall of the die-cutting roller so that the length direction of the main ruler is set along the width direction of the blade to be measured position, which is beneficial to improving the angle detection accuracy.

[0020] Optionally, an adjusting seat is provided between the main scale and the rotating seat, and the main scale is connected to the rotating seat through the adjusting seat; the adjusting seat is slidably connected to the rotating seat along the radial direction of the rotation axis, and the main scale is connected to the adjusting seat.

[0021] By adopting the above technical solution, when the blade to be measured is curved and spiral, rotating the rotating seat to make the main scale set along the width direction of the blade to be measured position, and sliding the adjusting seat, the vernier scale can be brought close to the blade to be measured position without moving the support block, making the operation simpler and more convenient.

[0022] Optionally, the sliding seat is threadedly connected to a locking screw, which is used to abut against the peripheral wall of the rotating shaft.

[0023] By adopting the above technical solution, the locking screw is rotated so that it abuts against the circumferential wall of the rotating shaft, thereby fixing the rotating seat and reducing the possibility of the rotating seat rotating, which would lead to a decrease in the accuracy of angle detection.

[0024] Optionally, the auxiliary ruler is provided with a measuring claw, and at least one side of the measuring claw along the length direction of the mounting rod is provided with a comparison surface, which is used to abut against the side wall of the die-cutting roller blade.

[0025] By adopting the above technical solution, after maintaining the predetermined angle between the vertex and the main scale, the tilt angle of the counterpart is known; by making the counterpart abut against the side wall of the blade to be measured, the tilt angle of the blade can be quickly obtained when the counterpart is in contact with the side wall of the blade. If the counterpart and the side wall of the blade are tilted, the tilt angle of the surface blade does not meet the standard.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. During the cutting process, the cutting angle of the die-cutting roller can be detected at any time, so that the processing amount can be adjusted according to the detected value. This reduces the difference between the actual value and the design value of the cutting angle of the die-cutting roller, thereby improving the processing accuracy of the die-cutting roller and increasing the yield. 2. The adjusting bolts and elastic elements work together to make the main ruler parallel to the rotating roller of the die-cutting cutter, thereby improving the detection accuracy. At the same time, it is easy to adjust the position of the main ruler and the secondary ruler according to the height of the blade. The structure is simple and the operation is convenient. 3. The measuring jaws are equipped with a comparison surface, which facilitates quick inspection of whether the blade tilt angle meets the standard. The operation is simple and fast.

[0035] The following is in conjunction with the appendix Figure 2 -Appendix Figure 6 This application will be described in further detail below.

[0036] Example 1 A die-cutting roller blade angle measuring instrument, referring to Figure 2The device includes a mounting rod 3 and two support frames 4, one of which is located at one end of the mounting rod 3, and the other at the other end. Each support frame 4 includes a mounting base 41, a support block 42, and an adjusting member 43. The mounting base 41 is located above the support block 42 and is connected to the support block 42 via the adjusting member 43. A connecting assembly 5 is provided between the mounting base 41 and the mounting rod 3, allowing the mounting base 41 to slide along the length of the mounting rod 3 to accommodate rollers 1 of different lengths. A clearance groove 421, a V-shaped groove, is formed on the lower surface of the support block 42 along the length of the mounting rod 3, allowing the support block 42 to be mounted on the outer peripheral wall of the roller 1 of the die-cutting cutter to be tested, thus positioning the mounting rod 3 above the roller 1.

[0037] Reference Figure 3 and Figure 4 The mounting rod 3 has a sliding groove 31 extending through it along its length. The connecting assembly 5 includes a connecting seat 51 and a sliding member 52. The mounting seat 41 is fixedly connected to the connecting seat 51 by screws. The sliding member 52 is located on the side wall of the connecting seat 51 opposite to the mounting seat 41. The sliding member 52 includes a support wheel 521 and two abutment wheels 522. The two abutment wheels 522 are arranged alternately along the length of the sliding groove 31. The support wheel 521 is located between the two abutment wheels 522, and both the support wheel 521 and the two abutment wheels 522 are rotatably connected to the connecting seat 51 via a pivot.

[0038] Reference Figure 3 and Figure 4 The support wheel 521 and the two abutment wheels 522 are all located within the sliding groove 31. The peripheral wall of the support wheel 521 abuts against the inner wall of one side of the sliding groove 31, and the peripheral walls of the two abutment wheels 522 abut against the inner wall of the other side of the sliding groove 31, thus allowing the connecting seat 51 to slide along the sliding groove 31. Limiting strips 311 are integrally formed on the inner walls of both sides of the sliding groove 31, with the length of the limiting strips 311 extending along the length of the sliding groove 31. Limiting annular grooves 5211 are respectively formed along their circumference on the peripheral walls of the support wheel 521 and the two abutment wheels 522. The limiting annular grooves 5211 engage with the corresponding limiting strips 311 to reduce the possibility of the connecting seat 51 disengaging from the mounting rod 3, thereby improving the stability of the sliding of the connecting seat 51. The mounting base 41 has a locking screw hole 411 extending through the sliding groove 31. A fastener 4111 is threaded onto the inner wall of the locking screw hole 411. The fastener 4111 includes a screw. By rotating the fastener 4111, the fastener 4111 can abut against the mounting rod 3, thereby fixing the mounting base 41.

[0039] Reference Figure 3 and Figure 4The connecting seat 51 has a through mounting hole 511 extending vertically, and the mounting seat 41 has a through guide hole 412 extending vertically. A guide rod 422 extending upwards is welded to the support block 42. The guide rod 422 is inserted into the guide hole 412 and is slidably connected to the inner wall of the guide hole 412. An adjusting screw hole 423 is provided on the upper surface of the support block 42. The adjusting component 43 includes an adjusting bolt 431 and an elastic component 432. The rod of the adjusting bolt 431 is inserted vertically into the mounting hole 511, and the rod of the adjusting bolt 431 is threaded into the adjusting screw hole 423. The elastic component 432 includes a spring. One end of the elastic component 432 abuts against the lower surface of the connecting seat 51 or the mounting seat 41, and the other end abuts against the upper surface of the support block 42. The elastic component 432 is in a compressed state to keep the upper surface of the connecting seat 51 in contact with the head of the adjusting bolt 431. Rotating the adjusting bolt 431 allows adjustment of the distance between the connecting seat 51 and the support block 42, enabling the mounting rod 3 to be leveled. In another embodiment, the mounting hole 511 can also be formed on the mounting seat 41; in another embodiment, the connecting seat 51 can also be integrally formed with the mounting seat 41.

[0040] Reference Figure 2 The mounting rod 3 is equipped with a sliding seat 32, which is equipped with a sliding member. The structure of the sliding member is the same as that of the sliding member 52, so that the sliding seat 32 can be connected to the inner wall of the sliding groove 31 through the sliding member, thereby allowing the sliding seat 32 to slide along the inner wall of the sliding groove 31. The sliding seat 32 is equipped with an angle detection element 6; in this embodiment, the angle detection element 6 is a digital angle ruler. The angle detection element 6 includes a main ruler 61, a secondary ruler 62, and an angle display element 63, which is a display screen; the main ruler 61 is bonded and fixed to the sliding seat 32, and the main ruler 61 is parallel to the mounting rod 3; when the secondary ruler 62 is rotated to a state where it is perpendicular to the main ruler 61 and extends downward, it is zeroed; then the secondary ruler 62 is rotated so that the side wall of the secondary ruler 62 is in contact with the side wall of the die-cutting roller blade 2, and the angle displayed by the angle display element 63 is the tilt angle of the side wall of the corresponding side of the blade 2. In another embodiment, the support block 42 can also be placed on the upper surface of the pad to adjust the horizontal tilt angle between the mounting rod 3 and the rotating roller 1 according to the shape of the blade 2, so as to detect the blade 2 that is spirally arranged along the axial direction of the rotating roller 1 or along the circumferential direction of the rotating roller 1. In another embodiment, the angle detection element 6 can also be a multi-functional angle ruler with a scale, and the corresponding scale is an angle display element 63.

[0041] Reference Figure 3The vernier scale 62 has a measuring claw 621 integrally formed at the end away from the main scale 61. There are two measuring claws 621. One measuring claw 621 is located on one side of the vernier scale 62 along its own width direction, and the other measuring claw 621 is located on the other side of the vernier scale 62. The sidewalls of the opposite sides of each measuring claw 621 are flush with the corresponding sidewalls of the vernier scale 62. The sidewalls of the opposite sides of the two measuring claws 621 are inclined to form a counter-opposite 6211. One end of the counter-opposite 6211 is connected to the end wall of the vernier scale 62, and the other end extends away from the vernier scale 62 along the length direction of the vernier scale 62 and is inclined away from the other measuring claw 621.

[0042] Reference Figure 3 When the vernier scale 62 is perpendicular to the main scale 61, the angle between each measuring claw 6211 and the vertical plane is a standard angle. In this embodiment, the standard angle of one measuring claw 621 is 20 degrees, and the standard angle of the other measuring claw 621 is 15 degrees. When detecting the blade angle, first make the vernier scale 62 perpendicular to the main scale 61, and then slide the sliding seat 32 to make the measuring claw 6211 abut against the side wall of the blade 2. If the measuring claw 6211 fits against the side wall of the corresponding side of the blade 2 being measured, it indicates that the inclination angle of the corresponding side wall of the blade 2 is equal to the corresponding standard angle; otherwise, they are not equal. In another embodiment, the number of measuring claws 621 can be one, three, or more. In another embodiment, the measuring claws 621 can also have measuring claws 6211 on both sides of the side wall along the width direction of the vernier scale 62.

[0043] Reference Figure 2 The sliding seat 32 is equipped with a distance detection element 321, which includes a dial indicator. The body of the distance detection element 321 is fixed to the sliding seat 32 by bolts, and the dial indicator head of the distance detection element 321 is used to abut against the outer peripheral wall of the rotating roller 1. By reciprocating the sliding seat 32 and observing the movement of the dial indicator needle, the parallelism of the mounting rod 3 relative to the rotating roller 1 can be determined, thereby improving the accuracy of angle detection. In another embodiment, the distance detection element 321 can also be a digital display rangefinder or other types of structural components used for distance detection.

[0044] The implementation principle of this application embodiment is as follows: In use, the mounting rod 3 is positioned above the rotating roller 1 of the die-cutting cutter to be tested. Then, the adjusting bolt 431 is rotated to adjust the height of the corresponding end of the mounting rod 3. The sliding seat 32 is slid along, and the movement of the pointer on the distance measuring element 321 is observed until the movement of the pointer on the distance measuring element 321 is within the specified error range, indicating that the mounting rod 3 is parallel to the rotating roller 1. The auxiliary ruler 62 is rotated downwards until it is perpendicular to the main ruler 61, and then zeroed. The sliding seat 32 is then slid along, and the auxiliary ruler 62 is rotated. When the side wall of the auxiliary ruler 62 is in contact with the side wall of the measured position of the cutter 2, the value displayed by the angle display element 63 is recorded. Similarly, the tilt angle of the side wall on the other side of the measured position of the cutter 2 can be measured. The absolute values ​​of the two values ​​are added together to obtain the cutter angle.

[0045] During the processing of the die-cutting roller cutter blade 2, the blade angle can be detected in time so that the processing amount can be adjusted in time, which helps to improve the processing accuracy of the die-cutting roller cutter blade 2.

[0046] Example 2 The difference between this embodiment and Embodiment 1 is that: Reference Figure 5 and Figure 6 A rotating seat 7 and an adjusting seat 8 are provided between the main scale 61 and the sliding seat 32, both located below the sliding seat 32. The sliding seat 32 has a rotating hole 322 extending vertically. A rotating shaft 71 extending upwards is welded to the rotating seat 7, passing through the rotating hole 322. The rotating shaft 71 protrudes from the outer peripheral wall of the rotating hole 322 and has a retaining ring groove 711. A spring retaining ring 712 is engaged within the retaining ring groove 711. The spring retaining ring 712 abuts against the upper surface of the sliding seat 32, allowing the rotating seat 7 to rotate relative to the sliding seat 32.

[0047] Reference Figure 5 and Figure 6 The rotating seat 7 is arranged radially along the rotating shaft 71, and the adjusting seat 8 is slidably connected to the rotating seat 7 along its length. The main scale 61 is bonded and fixed to the adjusting seat 8, and its length is arranged along the length of the rotating seat 7. When the length of the blade 2 of the die-cutting roller being measured is arranged along the axial direction of the rotating roller 1 or spirally along its circumference, the rotating seat 7 can be rotated so that its length is aligned with the width of the measured position of the blade 2. Then, the adjusting seat 8 is slid and the auxiliary scale 62 is rotated to detect the angle of the measured position of the blade 2. In this embodiment, the connection structure between the adjusting seat 8 and the rotating seat 7 can be referred to as the connection structure between the sliding seat 32 and the mounting rod 3, and will not be described in detail here. In this embodiment, the body of the distance detection component 321 is connected to the adjusting seat 8.

[0048] Reference Figure 6The sliding seat 32 has a fixing screw hole 323 that communicates with the rotating hole 322. The inner side wall of the fixing screw hole 323 is threaded with a locking screw 3231. When the locking screw 3231 is rotated, the end wall of the locking screw 3231 can abut against the peripheral wall of the rotating shaft 71 to fix the rotating shaft 71, thereby fixing the rotating seat 7 and improving the stability of the rotating seat 7.

[0049] Example 3 The difference between this embodiment and Embodiment 1 is that: Reference Figure 7 The mounting rod 3 is equipped with a lamp plate 33 and a light source 34, both located on one side of the vernier scale 62 along its thickness. A lamp holder 331 is welded to the lamp plate 33, and the end of the lamp holder 331 away from the lamp plate 33 is fixedly connected to the sliding seat 32 by screws. The light source 34 includes an LED light; the light source 34 is located on the side wall of the lamp plate 33 facing the vernier scale 62, and is bonded to the lamp plate 33 so that the light emitted by the light source 34 shines on the position where the vernier scale 62 abuts against the corresponding blade 2, thereby creating a shadow on the outer peripheral wall of the roller 1 on the side of the vernier scale 62 away from the light source 34.

[0050] Reference Figure 7 During the rotation of the vernier scale 62 towards the blade 2 to be tested, observe the shadows cast by the vernier scale 62 and the blade 2 on the rotating roller 1. When the shadows of the vernier scale 62 and the blade 2 are in contact with each other, it means that the sidewall of the vernier scale 62 is in contact with the corresponding sidewall of the blade 2. Otherwise, the position of the sliding seat 32 and the tilt angle of the vernier scale 62 need to be adjusted further. By illuminating with light, the imaging size of the gap between the vernier scale 62 and the blade 2 can be magnified for easier observation, thus ensuring that the sidewall of the vernier scale 62 is in contact with the sidewall of the blade 2, thereby improving the detection accuracy. In another embodiment, the position where the vernier scale 62 and the blade 2 are in contact can also be directly observed to confirm whether the light beam can be observed. When the light beam cannot be observed, it indicates that the sidewall of the vernier scale 62 is in contact with the sidewall of the blade 2. Otherwise, it indicates that the sidewall of the vernier scale 62 is not in contact with the sidewall of the blade 2, and further adjustment is required.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
