[0002] A cutting mechanism is a machine that applies a shearing force to materials of different cutting thicknesses through a moving upper blade and a fixed lower blade, and at the same time uses a reasonable blade gap to break and separate the materials according to the required dimensions. The adjustment of the blade gap is crucial for the use of the cutting mechanism.

[0003] In related technologies, there are certain drawbacks in the adjustment of the blade gap of the cutting mechanism. Usually, the lower blade is fixed on the piston rod of the cylinder, and the gap between the upper blade and the lower blade is adjusted through the cylinder. However, the accuracy of adjusting the blade gap by the cylinder is low, and the distance cannot be accurately controlled, which easily affects the actual cutting quality and brings adverse effects to the use process of people. In the field of precision cutting, the adjustment of the cutter gap is crucial for the product quality. Therefore, improving the adjustment accuracy of the blade gap is an urgent problem to be solved. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0034] The following will describe the embodiments of this application in conjunction with Figures 1 to 5 , to describe the embodiments of this application.

[0035] According to an embodiment of this application, a cutting device is provided, including: a base 1, a tool holder 2, a cutting mechanism 4, and an adjusting mechanism 5;

[0036] Specifically, the tool holder 2 is slidably connected to the base 1. The tool holder 2 is adapted to slide and switch between an initial position and a cutting position. The tool holder 2 is provided with an adjusting inclined surface 6, and a cutting tool 3 is arranged on the tool holder 2;

[0037] The cutting mechanism 4 is installed on the base 1. The cutting mechanism 4 is provided with a cutting end. In the state of the initial position, the cutting end is arranged corresponding to the cutting tool 3. In the state of the cutting position, a cutting gap is formed between the cutting end and the cutting tool 3 along the sliding direction of the tool holder 2;

[0038] The adjusting mechanism 5 is installed on the base 1. A driving inclined surface 7 is arranged on the adjusting end of the adjusting mechanism 5 corresponding to the adjusting inclined surface 6. The adjusting end is adapted to telescopically switch between a first position and a second position. When the adjusting end moves from the first position to the second position, the driving inclined surface 7 slidably abuts against the adjusting inclined surface 6, driving the tool holder 2 to move from the initial position to the cutting position, and adjusting the distance of the cutting gap.

[0039] The tool holder 2 is set at the initial position, and the cutting tool 3 is arranged corresponding to the cutting end of the cutting mechanism 4. Before performing the cutting operation, for different cutting materials and cutting standards, the distance of the cutting gap needs to be adjusted. When the adjusting end moves from the first position to the second position, the driving inclined surface 7 slidably abuts against the adjusting inclined surface 6 provided on the tool holder 2. The sliding abutment of the two inclined surfaces can drive the tool holder 2 to slide on the base 1, thereby adjusting the distance of the cutting gap. By driving the tool holder 2 to slide through the sliding abutment of the two inclined surfaces, the accuracy of the sliding distance of the base 1 can be improved. The distance that the driving inclined surface 7 moves is the driving distance, and the distance that the tool holder 2 slides is the adjusting distance. The driving inclined surface 7 can amplify the driving distance during adjustment and improve the accuracy of the adjusting distance. There is damping between the tool holder 2 and the base 1, which can ensure that the cutting gap does not change after being adjusted. The cutting end of the cutting mechanism 4 approaches the cutting tool 3 to cut the cutting material.

[0040] It needs to be further explained that taking Figure 1 , Figure 3 ,Figure 4 and Figure 5 Taking Figure 5 as an example, the tool holder 2 moves along the Y-axis direction, the cutting end of the cutting mechanism 4 moves along the Z-axis direction, and the adjusting end moves along the X-axis direction. The adjusting inclined plane 6 is perpendicular to the XY plane, extends along the positive X-axis direction and inclines towards the positive Y-axis direction. The driving inclined plane 7 is perpendicular to the XY plane, extends along the positive X-axis direction and inclines towards the positive Y-axis direction. When the driving inclined plane 7 moves along the negative X-axis direction, it can drive the tool holder 2 to move along the positive Y-axis direction.

[0041] It should be further noted that, as Figure 3 shown, a right triangle 13 formed by the driving inclined plane 7 as the inclined plane. The first right-angled side is arranged along the Y-axis direction, the second right-angled side is arranged along the X-axis direction. The length H of the first right-angled side is in a ratio of 1:10 to the length L of the second right-angled side. Therefore, when the driving inclined plane 7 moves 1 mm along the negative X-axis direction, it can drive the tool holder 2 to move 0.1 mm along the positive Y-axis direction, magnifying the driving distance during adjustment and improving the adjustment accuracy of the cutting gap.

[0042] It should be further explained that the direction in which the base 1 slides from the initial position to the cutting position is the positive Y-axis direction, and the direction in which the adjusting end moves from the first position to the second position is the negative X-axis direction.

[0043] In a specific embodiment, a connection hole 31 is provided on the cutting tool 3, and the cutting tool 3 is fixed on the tool holder 2 by a screw passing through the connection hole 31.

[0044] In an embodiment, as Figures 1 to 2 shown, it further includes at least one elastic member 8. The elastic member 8 is located on the side of the tool holder 2 close to the cutting position. One end of the elastic member 8 is connected to the base 1, and the other end is connected to the tool holder 2. Under the elastic force of the elastic member 8, the tool holder 2 has a tendency to slide along the direction from the cutting position to the initial position. When the adjusting end moves from the first position to the second position, that is, when moving along the negative X-axis direction, the driving inclined plane 7 and the adjusting inclined plane 6 are squeezed, driving the tool holder 2 to move from the initial position to the cutting position, increasing the cutting gap, and the elastic member 8 is compressed. When it is necessary to reduce the cutting gap, the adjusting end moves to the first position, the driving inclined plane 7 and the adjusting inclined plane 6 move away from each other, and under the action of the elastic member 8, the tool holder 2 moves to the initial position, and the cutting gap becomes smaller.

[0045] In a specific embodiment, as Figures 1 to 2 shown, it further includes a baffle 11. The baffle 11 is fixed on the base 1 and is located on one side of the tool holder 2 along the positive Y-axis direction. The elastic member 8 is a spring. One end of the spring is connected to the baffle 11, and the other end is connected to the tool holder 2. The spring is always in a compressed state.

[0046] What is further supplemented to the previous embodiment is, as Figure 1As shown, it includes two springs, and the two springs are located at both ends of the baffle 11 in the length direction.

[0047] In a specific embodiment, as Figure 2 shown, a plurality of fixing holes 14 are provided on the baffle 11, and a plurality of screws pass through the plurality of fixing holes 14 correspondingly to fix the baffle 11 on the base 1.

[0048] In one embodiment, the adjusting mechanism 5 includes:

[0049] A first driving mechanism 51, installed on the base 1;

[0050] An adjusting block 52, which is cut with a driving inclined surface 7. The adjusting block 52 is installed at the output end of the first driving mechanism 51. The first driving mechanism 51 drives the adjusting block 52 to switch telescopically between a first position and a second position. The driving inclined surface 7 is in sliding contact with the adjusting inclined surface 6 to adjust the distance of the cutting gap. The first driving mechanism 51 drives the adjusting block 52 to switch telescopically between the first position and the second position. With the driving inclined surface 7 provided on the adjusting block 52 in sliding contact with the adjusting inclined surface 6 and in cooperation with the elastic member 8, the size of the cutting gap is adjusted.

[0051] In one embodiment, as Figure 2 shown, the tool holder 2 is provided with a notch 9 corresponding to the adjusting block 52. The side wall of the notch 9 is provided with an adjusting inclined surface 6. The first driving mechanism 51 drives the adjusting block 52 to penetrate into and out of the notch 9 to adjust the distance of the cutting gap.

[0052] In a specific embodiment, as Figure 2 shown, the notch 9 is set as an L-shaped notch 9. One side of the notch 9 is set as the adjusting inclined surface 6. Setting the notch 9 does not affect the overall structure and volume of the tool holder 2.

[0053] In one embodiment, as Figure 2 shown, the output shaft of the first driving mechanism 51 is a lead screw 511. The adjusting block 52 is provided with a threaded hole 521 corresponding to one end of the lead screw 511. The lead screw 511 is screwed with the threaded hole 521. The side surface of the adjusting block 52 is in sliding contact with the base 1. The first driving mechanism 51 drives the lead screw 511 to rotate. The lead screw 511 is threadedly connected with the threaded hole 521 on the adjusting block 52. The side surface of the adjusting block 52 is in sliding contact with the base 1, which can limit the rotation of the adjusting block 52. When the lead screw rotates, it can drive the adjusting block 52 to move along the positive or negative X direction, thereby adjusting the distance of the cutting gap.

[0054] It should be further explained that by rotating the lead screw 511 to drive the adjustment block 52 to move, the driving distance during adjustment is further amplified, and the adjustment accuracy of the cutting gap is improved. For example, when the lead screw 511 rotates one full turn, the adjustment block 52 moves 1 mm. By rotating the lead screw 511, when it rotates a quarter of a turn, it moves 0.25 mm, further improving the adjustment accuracy of the cutting gap.

[0055] When it is necessary to adjust the cutting gap by 0.01 mm, it only needs to move 0.1 mm along the X-axis direction. Then, through the lead screw 511, the 0.1 mm movement is amplified into a 360-degree rotation in one circle, thus achieving precise control of the cutting gap.

[0056] In a specific embodiment, the first driving mechanism 51 is a screw adjuster. The screw adjuster includes a connecting frame and a handle. The connecting frame is fixed on the base 1. The lead screw 511 is rotatably connected to the connecting frame. One end of the lead screw 511 is connected to the threaded hole 521, and the other end is connected to the handle.

[0057] In an embodiment, the first driving mechanism 51 is a servo motor. The output shaft of the servo motor is coaxially fixed with the lead screw 511. The servo motor has excellent response speed, can start, stop and reverse quickly, its dynamic response time is short, generally within dozens of milliseconds, and it can meet the application occasions with high requirements for real-time motion control; and it is energy-saving and efficient.

[0058] In an embodiment, the cutting mechanism 4 includes:

[0059] A mounting frame 41, connected to the base 1;

[0060] A second driving mechanism 42, mounted on the mounting frame 41, and the driving end of the second driving mechanism 42 can approach or move away from the cutting tool 3;

[0061] A cutting tool 43, connected to the driving end of the second driving mechanism 42, and used to cooperate with the cutting tool 3 for cutting.

[0062] The driving end of the second driving mechanism 42 can drive the cutting tool 43 to approach or move away from the cutting tool 3 to complete the cutting operation.

[0063] It should be explained that as Figure 1 shown, both the cutting tool 43 and the cutting tool 3 are arranged along the X-axis direction.

[0064] In a specific embodiment, the mounting frame 41 is a U-shaped plate. The ends of the two side plates of the U-shaped plate are connected to the base 1. The connecting plate 44 is located between the two side plates of the U-shaped plate, and the second driving mechanism 42 is mounted on the top plate of the U-shaped plate.

[0065] Supplementing the previous embodiment, the second driving mechanism 42 is a cylinder. The cylinder barrel of the cylinder is fixed on the top plate of the U-shaped plate, and the cutter 43 is connected to the piston rod of the cylinder.

[0066] In a specific embodiment, as Figures 1 to 2 shown, two cylinders are provided. The cylinder barrels of the two cylinders are fixed on the top plate of the U-shaped plate, and their piston rods are arranged in parallel.

[0067] In an embodiment, it further includes a connecting plate 44. The connecting plate 44 is connected to the driving end of the second driving mechanism 42, and the cutter 43 is installed on the connecting plate 44. The connecting plate 44 facilitates the installation of the cutter 43 on the driving end of the second driving mechanism 42.

[0068] It should be further noted that the connecting plate 44 is fixed on the piston rod of the cylinder.

[0069] In an embodiment, a chute is provided on the base 1. The chute is arranged along the direction from the initial position to the cutting position. The bottom of the tool holder 2 is connected with a slider, and the slider is slidably connected with the chute. The chute is arranged along the Y-axis direction, which can guide the sliding of the tool holder 2 and make it slide along the Y-axis direction.

[0070] In an embodiment, it further includes a distance measurer 10. The distance measurer 10 is installed on the base 1, and the distance measurer 10 is used to measure the distance that the tool holder 2 moves from the initial position to the cutting position.

[0071] In a specific embodiment, the distance measurer 10 is a distance sensor. The distance sensor is installed on the baffle 11. When the tool holder 2 is in the initial position, the cutting tool 3 is aligned with the cutter 43, the cutting gap is zero, and the sensing value of the distance sensor is zero. When the adjusting block 52 adjusts the cutting gap, the distance sensor can perform distance measurement in real time, and the measured value is the distance of the cutting gap.

[0072] In another specific embodiment, as Figures 1 to 2 shown, the distance measurer 10 is a micrometer. An installation hole 12 is provided on the baffle 11 along the Y-axis direction. The micrometer is installed in the installation hole 12, and its measuring end abuts against the tool holder 2. When the tool holder 2 is in the initial position, the cutting tool 3 is aligned with the cutter 43, the cutting gap is zero, and the value of the micrometer is zero. When the adjusting block 52 adjusts the cutting gap, the micrometer can perform distance measurement in real time, and the measured value is the distance of the cutting gap.

[0073] Supplementing the previous embodiment, as Figures 1 to 2 shown, it includes two micrometers. The two micrometers abut against both ends of the tool holder 2 along the X-axis direction to improve the measurement accuracy.

[0074] In a specific embodiment, the distance measurer 10 is an electronic distance measuring device such as an electronic ruler.

[0075] The following takes an embodiment and combines Figures 1 to 5 to fully elaborate on all the above solutions.

[0076] Before cutting, it is necessary to adjust the cutting gap between the cutter 3 and the cutting knife 43 according to the material to be cut and the cutting standard. The tool holder 2 is in the initial position, the cutter 3 is aligned with the cutting knife 43, the cutting gap is zero, and the values of the two dial indicators are zero. Input the distance data of the movement of the adjusting block 52 driven by rotating the lead screw 511 for one week and the ratio data of the first right-angled side to the second right-angled side of the right-angled triangle 13 formed by the driving inclined surface 7 into the PLC. The servo motor is communicatively connected to the PLC (programmable logic controller). The cutting gap is set through the PLC, and the PLC controls the rotation of the servo motor. The lead screw 511 drives the adjusting block 52 to move, and the driving inclined surface 7 is in sliding abutment with the adjusting inclined surface, driving the tool holder 2 to move along the Y-axis direction, increasing the cutting gap. The spring is compressed to tightly hold the tool holder 2 to prevent the cutting gap from changing during the cutting process. As the cutting gap increases, the values of the two dial indicators also increase, which can display the size of the cutting gap in real time and improve the adjustment accuracy of the cutting gap. When it is necessary to reduce the cutting gap, the PLC controls the servo motor to reverse, causing the driving inclined surface 7 to move away from the adjusting inclined surface 6. Under the action of the spring, the tool holder 2 moves towards the initial position to reduce the cutting gap.

[0077] This application is applicable to various devices and industries that require precise cutting, such as the cutting fields of electronic components, fabrics, papers, etc. By accurately adjusting the cutting gap and displaying the gap size in real time, the smoothness of the cutting edge and the stability of the product quality can be ensured.
