Description

Technical Field

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

[0002] Automatic cutting machines are used for cutting and slitting sheet materials in various industries. They require no molds; controlled by system software, they directly cut the material. Simply set the relevant parameters on the operating platform, and the computer transmits the corresponding instructions to the cutting machine. The machine then quickly cuts according to the received design drawings, boasting 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 yield. To avoid this problem, the industry commonly uses an intelligent blade correction device to adjust the blade's posture, effectively improving this issue and thus increasing the product yield.

[0004] Existing intelligent cutting blade correction devices generally adopt an integrated design of blade clamping and pressure sensing. When the cutting blade twists, the upper and lower clamping rollers are simultaneously subjected to pressure in opposite directions. Figure 1 As shown, the force on the upper clamping roller can easily interfere with the pressure sensing sensor. Under some complex working conditions, the detection signal may become disordered or the detection speed may be reduced, which will seriously affect the cutting quality. Utility Model Content

[0005] The purpose of this invention is to provide a split-type cutting blade correction device. By using a separate blade clamping module and a pressure sensing module, the blade clamping module does not participate in pressure sensing detection, thus eliminating force interference, improving the accuracy of detection data, and further enhancing the cutting quality.

[0006] This utility model provides the following technical solution: a split-type cutting blade correction device, comprising a blade clamping module and a pressure sensing module, characterized in that: the blade clamping module and the pressure sensing module are stacked vertically, the pressure sensing module is provided with symmetrical lower clamping rollers, the cutting blade is inserted into the blade clamping module and the pressure sensing module in sequence, keeping perpendicular to the horizontal plane of both, and the cutting blade is inserted between the lower clamping rollers, and a pressure sensor mounting groove is opened on the outer surface of the pressure sensing module, and a pressure sensor is fixed in the pressure sensor mounting groove.

[0007] The clamping module is rotatably connected to a pair of symmetrically distributed upper clamping rollers, which are arranged parallel to each other. The clamping module is also rotatably connected to a side roller, which is located between the upper clamping rollers, and the axis of the side roller is perpendicular to the axis of the upper clamping roller.

[0008] The pressure sensing module is also connected to an inner frame by fasteners, and the lower clamping roller is rotatably connected to the inner frame.

[0009] The inner wall of the pressure sensing module has two pairs of four symmetrically distributed double arc-shaped deformation grooves on both sides, and the pressure sensor mounting groove is formed on the outside of the arc-shaped deformation grooves.

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

[0011] (1) By separating the knife clamping module and the pressure sensing module, the knife holding and pressure sensing functions are separated. The knife clamping module does not participate in the pressure sensing detection, thus eliminating force interference, improving the accuracy of the detection data, and further improving the cutting quality.

[0012] (2) Due to the adoption of a split modular design, production flexibility is increased. Different specifications of clamping modules and pressure sensing modules can be flexibly configured according to different needs, which effectively reduces production costs. At the same time, it is easy to maintain. When a fault occurs, the damaged module can be replaced separately without replacing the whole module, thus reducing the user's maintenance costs.

[0019] 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.

[0020] Example 1

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a split-type cutting blade correction device, including a blade clamping module 1 and a pressure sensing module 2. The blade module 1 and the pressure sensing module 2 are stacked vertically. The pressure sensing module 2 is provided with symmetrical lower clamping rollers 6. The cutting blade is inserted into the blade clamping module 1 and the pressure sensing module 2 in sequence, keeping it perpendicular to the horizontal plane of both, and the cutting blade is inserted between the lower clamping rollers 6. The lower clamping rollers 6 control the cutting blade. A pressure sensor mounting groove 4 is opened on the outer surface of the pressure sensing module 2, and a pressure sensor is fixed in the pressure sensor mounting groove 4. When the cutting blade is cutting, it is subjected to the pressure of the soft material, causing the cutting blade to twist and deviate. The lower clamping roller 6 on one side applies pressure to the lower clamping roller 6. The pressure is transmitted to the pressure sensing module 2. The outer surface of the pressure sensing module 2 has symmetrically distributed sensor mounting slots 4 for mounting pressure sensors. The pressure is transmitted to the sensor mounting slots 4, causing the pressure sensor to deform and generate a signal. The pressure value on both sides of the blade can be obtained from the signal, so as to facilitate the adjustment of the cutting blade posture according to the pressure. Since the blade clamping module 1 and the pressure sensing module 2 are independent of each other, the pressure applied by the cutting blade to the blade clamping module will not affect the pressure sensing module 2. The pressure sensor will not be interfered with, and the accuracy of the detection data is guaranteed.

[0022] like Figure 3 and 4 As shown, a pair of symmetrically distributed upper clamping rollers 5 are rotatably connected inside the clamping module 1. The upper clamping rollers 5 and the lower clamping rollers 6 are distributed parallel to each other vertically. A side roller 3 is also rotatably connected inside the clamping module 1. The side roller 3 is located between the upper clamping rollers 5. The axis of the side roller 3 is perpendicular to the axis of the upper clamping rollers 5. The upper clamping rollers 5 support the upper two sides of the cutting blade.

[0023] The pressure sensing module 2 is also connected to an inner frame by fasteners. The lower clamping roller 6 is rotatably connected to the inner frame. The pressure sensing module 2 is designed as a separate unit by the inner frame. The inner frame is small in size, has good rigidity and is not easily deformed. Connecting the inner frame to the pressure sensing module 2 enhances the rigidity of the outer ring of the pressure sensing module 2.

[0024] The inner wall of the pressure sensing module 2 has two pairs of four symmetrically distributed double arc-shaped deformation grooves on both sides. The pressure sensor mounting groove 4 is formed on the outside of the arc-shaped deformation grooves. Through the four double arc-shaped deformation grooves, the edge of the pressure sensing module 2 is more likely to deform under pressure, thereby applying pressure to the sensor and improving the accuracy of detection.

[0025] 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.
