Description

Technical Field

[0001] This utility model relates to the field of cutting blade correction technology, specifically to a cutting blade intelligent correction device. Background Technology

[0002] Automatic cutting machines are used for cutting and slitting sheet materials in various industries. They do not require any molds; they are controlled by system software and directly cut the products. Simply set the relevant parameters on the operating platform, and the computer transmits the corresponding instructions to the cutting machine. The cutting machine then quickly cuts according to the received design drawings, with a high degree of automation and simple operation. It is currently the cutting equipment used in many industries.

[0003] When cutting thick, soft materials, cutting machines often deform the blade due to the force between the blade and the material, making it unable to maintain perpendicularity. This results in a significant size difference between the upper and lower cut pieces, leading to a decrease in product qualification rate. To avoid this problem, the industry commonly uses an intelligent blade correction device that adjusts the blade angle, effectively improving this issue and significantly increasing the product qualification rate.

[0004] Existing intelligent cutting tool correction devices generally adopt an integrated design. First, corresponding specifications must be manufactured to fit different sizes of cutting tools, resulting in poor versatility and increased production costs. Second, if a malfunction or damage occurs during use, the entire device must be replaced, leading to high maintenance costs for users. Third, they generally lack ventilation holes, resulting in low heat dissipation capacity and affecting the lifespan of the device to some extent. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent cutting tool correction device, which adopts a modular design, dividing the device into a tool clamping module and a pressure sensing module, both manufactured separately. The tool clamping module is produced according to the required tool specifications. The pressure sensing module can be mass-produced as a standard component.

[0006] This utility model provides the following technical solution: a cutting knife intelligent correction device, including a knife clamping module, wherein two sets of symmetrically distributed holding rollers are installed in the knife clamping module. The two sets of holding rollers are distributed vertically, including an upper clamping roller and a lower clamping roller. The cutting knife is inserted between the upper clamping roller and the lower clamping roller in sequence. At the same time, a side roller is also installed in the knife clamping module. The rotation axis of the side roller is perpendicular to the rotation axis of the upper clamping roller and the rotation axis of the lower clamping roller, which is used to support the back of the cutting knife.

[0007] To facilitate production and maintenance, a pair of pressure sensing modules are symmetrically installed on both sides of the clamping module. Each pressure sensing module has a deformation hole, and a patch groove is formed on the outside of the deformation hole. A stress sensor is attached to the patch groove.

[0008] To facilitate sensor wiring, a circuit board mounting plate is also fixed to the clamping module by bolts. The circuit board mounting plate is used to install an adapter circuit board, which is used to connect to the stress sensor.

[0009] In order to effectively reduce the operating temperature of the device and avoid overheating that could damage the sensor, thereby extending the device's service life, two ventilation holes are provided on the side of the clamping module, one above the other, and ventilation holes are also provided at corresponding positions on the end plate of the pressure sensing module.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0011] 1. The upper and lower clamping rollers support the cutter to prevent deformation, while the side rollers support the back of the cutter to ensure the quality of the cut.

[0012] 2. Modular design facilitates production and reduces production costs; it increases production flexibility, allowing for flexible configuration of different specifications of clamping modules and pressure sensing modules according to different needs. By using sensors to detect pressure, it further facilitates the adjustment of the cutting blade, ensuring that the force on both sides of the cutting blade is even and guaranteeing the quality of cutting.

[0013] 3. Easy to maintain: When a fault occurs, only the damaged module needs to be replaced, instead of replacing the whole unit, reducing the user's maintenance costs;

[0014] 4. Ventilation holes can effectively reduce the operating temperature of the device and extend its service life. Attached Figure Description

[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. Example

[0026] Please see Figures 1 to 4This utility model provides a technical solution: an intelligent cutting knife correction device, including a knife clamping module 1. The knife clamping module 1 has two sets of symmetrically distributed holding rollers, arranged vertically, including an upper clamping roller 2 and a lower clamping roller 11. The cutting knife is inserted sequentially between the upper clamping roller 2 and the lower clamping roller 11. Simultaneously, the knife clamping module 1 also has side rollers 9 installed. The axis of rotation of the side rollers 9 is perpendicular to the axis of rotation of the upper clamping roller 2 and the axis of rotation of the lower clamping roller 11, serving to support the back of the cutting knife. When the cutting knife cuts the material, due to the material's thickness, the cutting knife will exert force with the material, causing deformation. This causes the cutting knife to deviate to one side, applying pressure to one side of the upper clamping roller 2 or lower clamping roller 11. Simultaneously, the upper clamping rollers 2 or lower clamping rollers 11 on both sides support the cutting knife, preventing it from deviating due to pressure during cutting. The blade clamping module 1 is symmetrically equipped with a pair of pressure sensing modules on both sides, including a left pressure sensing module 4 and a right pressure sensing module 8. The left pressure sensing module 4 has a left deformation hole 5, and a left sensor patch groove 12 is formed on the outside of the left deformation hole 5. A stress sensor is attached to the left sensor patch groove 12. The right pressure sensing module 8 has a right deformation hole 7, and a right sensor patch groove 13 is formed on the outside of the right deformation hole 7. A stress sensor is attached to the right sensor patch groove 13. When the cutting blade is pressed, the pressure is transmitted to the upper clamping roller 2 or the lower clamping roller 11 on one side, and further transmitted to the left pressure sensing module 4 or the right pressure sensing module 8. The stress sensor detects the pressure and determines the magnitude of the pressure on both sides of the blade. Then, the position of the blade is adjusted according to the magnitude of the pressure to make the blade bear force evenly, ensuring that the material cut size is consistent, the cut hole is smooth, and the cut quality is improved.

[0027] The clamping module is also fixed with a circuit board mounting plate 6 by bolts. The circuit board mounting plate 6 is used to install the adapter circuit board, which is used to connect with the stress sensor, making the wiring between the stress sensor and the adapter circuit board convenient.

[0028] Each side of the clamping module 1 has two vertically distributed ventilation holes: an upper left ventilation hole 16 and a lower left ventilation hole 17 on the left side, and an upper right ventilation hole 18 and a lower right ventilation hole 19 on the right side. The end plate of the left pressure sensing module 4 also has an upper left ventilation hole 3 and a lower left ventilation hole 10. The upper left ventilation hole 3 corresponds to the upper left ventilation hole 16 of the clamping module. The lower ventilation hole 10 of the force sensing module corresponds to the lower left ventilation hole 17 of the clamping knife module. The upper ventilation hole 14 and the lower ventilation hole 15 of the right pressure sensing module are also opened at the corresponding positions on the end plate of the right pressure sensing module 8. The upper ventilation hole 14 of the right pressure sensing module corresponds to the upper right ventilation hole 18 of the clamping knife module, and the lower right ventilation hole 19 of the clamping knife module corresponds to the lower right ventilation hole 15 of the right pressure sensing module. This improves the ventilation performance of the clamping knife module 1, reduces the temperature of the device in the working state, improves the heat dissipation capacity, and extends the service life.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
