[0033] Example 1:

[0034] Please see Figures 1-9 The present invention discloses a foam circular cutter with an adaptive adjustment mechanism and its working method, comprising a frame 1; an adjustment component 2 with height adjustment function is provided in the left and right side columns at the top of the frame 1, and the adjustment component 2 is specifically composed of a motor, a gear on the motor drive shaft, a chain meshing with the gear, and a moving plate on one side of the chain; a placement roller 3 for placing foam is slidably installed at the front end of the moving plate of the adjustment component 2; a control cabinet 4 with control function is fixedly installed on the side of the right side column at the top of the frame 1 by bolts; a rear frame 5 is fixedly installed on the rear side of the frame 1 by bolts, and a guide roller assembly 6 and a cutter assembly 7 are provided on the top side of the frame 1.

[0038] Example 2:

[0039] Please see Figures 1-9 The present invention provides a foam circular cutter with an adaptive adjustment mechanism and its working method. Compared with Embodiment 1, this embodiment further includes: the cutter assembly 7 includes an adjustment arm 71 fixedly installed on the top side of the frame 1 for multi-axis adjustment; a blade holder 72 is fixedly installed at the end of the adjustment arm 71 by bolts; a photosensitive sensor 73 with data acquisition function is fixedly installed on the side of the adjustment arm 71 by bolts, and a sensor with data sensing function with the photosensitive sensor 73 is provided on the column on the top side of the frame 1.

[0040] A mounting rod 74 is fixedly inserted into the side of the blade holder 72, and the mounting rod 74 is inserted into the inner groove of the cutting tool 75; the surface of the cutting tool 75 is also provided with a functional coating 76, and the inner wall of the cutting tool 75 is also covered with a heat-conducting pipe 77 for heat exchange; both ends of the heat-conducting pipe 77 are connected to the external heating unit pipes through connectors 78; the functional coating 76 is specifically a hard wear-resistant coating, and multiple sets of microcapsules are uniformly dispersed and embedded in the hard wear-resistant coating; the shell of the microcapsule is a brittle polymer material, and the inside is encapsulated with low viscosity repair monomers and catalysts.

[0041] The working principle of the foam circular cutter with an adaptive adjustment mechanism and its working method described above is as follows:

[0042] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0043] Second, the foam blank to be cut is placed on the placement roller 3, and the foam blank is conveyed downward to the top of the guide roller assembly 6 through the placement roller 3 by the adjusting component 2. Here, the external airflow is introduced into the fixed roller body 61 through the rotary joint 64, and sprayed onto the membrane body 633 through the air guide hole 62. During this process, the control cabinet 4 supplies a specific current to the coil 636, and the coil 636 generates a controllable electromagnetic field. Here, the foam blank is driven to continue to move downward and contact the membrane body 633 through the adjusting component 2.

[0044] Third, when the metal wire mesh 634 and the membrane 633 are subjected to the pressure of the external foam blank and undergo slight deformation, under the action of the isolation sleeve 635 and the permanent magnet ring shell, the resistance detector 637 detects the change in resistance of the coil circuit formed by the coil 636 and the current output device 638. Here, the membrane 633 rubs against the foam, causing it to drive the metal wire mesh 634 and the rotating gear ring 631 to rotate. Here, the driving gear 654 and the driven gear 657 rotate accordingly. The light source 656 and the combined photosensitive plate 655 accurately monitor the displacement and angle of this movement to determine the detection area determined by the foam rotation angle meter.

[0045] Fourth, the control cabinet 4 integrates and analyzes the detection data with the input current and voltage signals. Combined with the preset mechanical model, it can calculate the overall roundness of the local surface of the foam in the current contact area in real time, thereby establishing an accurate material property map before cutting. The control cabinet 4 uses the material property map obtained in the above steps to adjust the spatial position of the blade holder 72 and the cutting tool 75 by adjusting the arm 71. Here, the tool angle is determined by data mutual induction between the photosensitive sensor 73 and the sensor set on the column of the frame 1. The adjusting arm 71 drives the cutting tool 75 to move along the planned path for cutting. During the cutting process, the control cabinet 4 commands the servo motor 651 of the detection component 65 to work. Through the transmission of the horizontal shaft 652, integrated bearing 653, driving gear 654 and driven gear 657, the rotating gear ring 631 drives the entire air film component 63 to perform small-amplitude reciprocating or rotating movements. At the same time, the light source 656 and the combined photosensitive plate 655 accurately monitor the displacement and angle of this movement. Here, the membrane 633 rubs against the foam, causing the foam to rotate.

[0046] Fifth, throughout the cutting process, the external heating unit circulates the heat transfer medium through the connector 78 and the heat pipe 77 to precisely control the temperature of the cutting tool 75. This not only prevents the tool from overheating and softening, but also allows for appropriate temperature increases when needed, enabling the functional coating 76 to perform better and potentially triggering a self-repairing preparation state. Under the combined action of cutting friction or active temperature control by the system, when the functional coating 76 experiences microscopic wear, the shell of the embedded microcapsules ruptures, and the outflowing repair monomers rapidly polymerize under the activation of frictional heat or auxiliary heat from the heat pipe 77, filling the worn area in situ, thereby partially restoring the coating performance and extending the effective service life of the tool.

[0047] This invention provides an improved foam circular cutter with an adaptive adjustment mechanism and its working method. By integrating the guide roller assembly 6 and the cutter assembly 7, it achieves a complete technical closed loop of online material sensing, intelligent path planning, adaptive cutting execution, and cutter self-repair maintenance, resulting in a significant improvement in foam cutting quality and intelligent production process. It can accurately detect the mechanical properties of the foam before cutting and automatically match the optimal process to ensure cutting accuracy and consistency. At the same time, the self-repair function and predictive maintenance capability of the cutter greatly extend the life of key consumables and reduce overall costs.
