Environmental design encompasses a wide range of areas, including urban design, landscape and garden design, and the technical and artistic aspects of architecture and interior design. In the environmental design process, modeling is one of the fundamental languages ​​through which designers think and express themselves. Through modeling, designers can more intuitively understand design intent, refine design details, improve spatial control, and enhance their design skills. Furthermore, modeling helps students fully understand the design thinking and ideas of masters, enhancing their innovative awareness and practical skills.

[0003] Cutting model material is a crucial task in the production of environmental design models. Current cutting methods often rely on manual shearing with scissors, which is highly repetitive, labor-intensive, and inefficient. Furthermore, when working with harder materials, different cutting tools must be used, resulting in inconsistent cutting results. Therefore, a device is needed that can efficiently, quickly, and conveniently cut model material. Utility Model Content

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example:

[0029] like Figures 1 to 6As shown, a model cutting device includes two groups of handles 1. The left ends of the two groups of handles 1 are staggered and hinged by rivets 8. Both groups of handles 1 are provided with anti-skid covers 2 for preventing slipping. The anti-skid covers 2 increase the friction of the handles 1 to prevent slipping during use and improve safety. A button switch 7 is embedded in the anti-skid covers 2 of one group of handles 1. The embedding of the button switch 7 makes the operation more convenient. Cutting can be started with just a light press, and it is convenient for one-handed operation. The tail end of the group of anti-skid covers 2 is connected to a power cord 3 with a plug, and the power cord 3 is electrically connected to the button switch 7. The power cord 3 is used to connect to an external power supply to provide power for the device. The left end of the lower handle 1 is fixed with an upper clamp plate 4, and the left end of the upper handle 1 is fixed with a lower clamp plate 5. The upper clamp plate 4 is vertically opened with a through saw groove 19. A saw blade 11 is installed inside 19, and the saw blade 11 is fixed inside the saw groove 19 through a support shaft 18. The rear end of the support shaft 18 extends out of the upper clamp plate 4 and is equipped with a driven pulley 17. A motor 10 is installed on the upper surface of the upper clamp plate 4 near the right end, and a driving pulley 15 is installed on the output end of the motor 10. The driving pulley 15 is connected to the driven pulley 17 through a transmission belt 16. The motor 10 drives the driving pulley 15 and is connected to the driven pulley 17 through the transmission belt 16, thereby realizing the rotation of the saw blade 11, thereby performing cutting. This design solves the problem that the existing model raw material plate cutting method often uses manual scissors for manual shearing, which has strong repetitiveness, high labor intensity, low cutting efficiency, and when encountering raw material plates with harder materials, it is necessary to replace different cutting tools for cutting, and the cutting effect is unstable.

[0030] In this embodiment, an arc-shaped protective cover 9 is installed on the upper surface of the upper clamp plate 4 in the saw groove 19. The protective cover 9 covers the upper half of the saw blade 11. The protective cover 9 can separate the saw blade 11 from the external environment to prevent the saw blade 11 from being exposed and injuring people. At the same time, it protects the operator from being hurt by splashes or debris that may be generated when the saw blade 11 rotates, ensuring the safety of the operator.

[0031] In this embodiment, heat dissipation holes 91 are opened on the surface of the protective cover 9. The design of the heat dissipation holes 91 can effectively discharge the heat generated by the saw blade 11, prevent heat from accumulating in the protective cover 9, and help dissipate heat from the saw blade 11.

[0032] In this embodiment, a chip groove 20 adapted to the saw groove 19 is opened inside the lower clamp plate 5, and the position of the chip groove 20 corresponds to the position of the saw groove 19. The chip groove 20 can match the lower half of the saw blade 11 to prevent the saw blade 11 from contacting the lower clamp plate 5 and hindering its normal operation. At the same time, the design of the chip groove 20 can effectively discharge the waste generated during the cutting process, avoiding the accumulation of waste in the cutting area, thereby keeping the cutting area clean.

[0033] In this embodiment, multiple sets of freely rotatable guide balls 13 are embedded in the bottom surface of the upper nipper 4 and the upper surface of the lower nipper 5. The guide balls 13 are located to the left of the chip flute 20. The presence of the guide balls 13 allows the material to slide more smoothly when it is fed between the upper nipper 4 and the lower nipper 5. The free rotation of the balls reduces friction between the material and the nippers, allowing the material to be more easily guided to the saw blade 11 for cutting.

[0034] In this embodiment, two sets of guide pads 12 are provided on the bottom surface of the upper nipper 4 and the upper surface of the lower nipper 5. These two sets of guide pads 12 are respectively arranged on the front and rear sides of the saw groove 19 and the chip groove 20. The upper surfaces of the guide pads 12 are flush with the apex of the guide balls 13. The main function of the guide pads 12 is to support the material to be cut and keep it in a horizontal state, effectively preventing skew during the cutting process, thereby greatly improving cutting accuracy.

[0035] In this embodiment, a centering groove line 14 is provided on the left end surface and the center of the opposite surface of the upper nipper plate 4 and the lower nipper plate 5. The centering groove line 14 is aligned with the vertical surface of the saw blade 11. The set centering groove line 14 provides an operator with a clear visual reference, which guides the cutting of the material to be cut, helps to ensure that the saw blade 11 can cut along the expected path during cutting, avoids deviation or skew, and ensures the cutting accuracy of the material to be cut.

[0036] The working principle of this model cutting device is as follows: During actual use, the device is connected to an external power source via a power cord 3 to provide power to the motor 10. The operator presses the button switch 7 on the anti-slip sleeve 2 to start the motor 10, which drives the driving pulley 15 to rotate. The driving pulley 15 drives the driven pulley 17 to rotate via the transmission belt 16. The driven pulley 17 is fixed to the support shaft 18, which in turn fixes the saw blade 11, so that the saw blade 11 rotates accordingly. The material to be cut is placed between the upper nipper 4 and the lower nipper 5. The upper nipper 4 and the lower nipper 5 clamp and position the material to be cut, while ensuring that the cutting path on the material is aligned with the centering groove line 14. The device is held by the handle 1 and moved along the cutting path on the material. During this process, the material to be cut is cut by the saw blade 11. After cutting is completed, the button switch 7 is released, the motor 10 stops working, and the saw blade 11 stops rotating. The cut material is removed and the waste material in the chip chute 20 is cleaned.

[0037] In summary, the model cutting device achieves efficient and precise cutting operations by electrically driving the saw blade 11 to rotate. At the same time, its safety protection design and precise centering function ensure the safety of the operator and the accuracy of cutting. The use process is simple and clear, and it is easy to operate and maintain.

[0038] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
