[0002] Sanding the polystyrene car hood model is a crucial step in refining the initially formed model to its ideal state. First, coarse sandpaper is used for initial sanding to remove excess edges and uneven areas, quickly correcting the model's general outline. Then, fine sandpaper is used for fine sanding, further eliminating traces left by the coarse sanding, making the surface smoother and highlighting the hood's detailed texture. During sanding, it's important to apply even pressure to avoid over-sanding in certain areas, which could deform the model. After sanding, polishing compound or a polishing cloth can be used to polish the surface, enhancing the model's smoothness and texture, making it more closely resemble the appearance of a real car hood. The quality of the polystyrene model's sanding directly affects the final result, impacting the model's precision and aesthetics.

[0003] Currently, existing grinding devices for polystyrene car engine hood models typically use a motor to drive a grinding block to grind the model. However, during the grinding process, a large amount of debris is ejected. Traditional grinding devices for polystyrene car engine hood models often lack adequate protective structures, causing the debris to scatter irregularly in all directions. This can result in operators standing in front of the device being hit by the debris, thus reducing the safety of the device. Utility Model Content

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.

[0023] Please see Figures 1-4The present invention provides the following technical solution: a grinding device for a polystyrene car engine hood model, including a processing table 1, two fixed frames 2 are fixedly connected to the top of the processing table 1, a connecting frame 3 is connected to the top of the two fixed frames 2, a first motor 4 is installed at one end of the connecting frame 3, a lead screw 5 is connected to the output end of the first motor 4, and a threaded connecting block 6 is threadedly connected to the outer wall of the lead screw 5.

[0024] A guide rod 7 is fixedly connected to the inner side of the connecting frame 3. A grinding component 8 is installed at the bottom of the threaded connecting block 6. An installation groove 9 is opened at the bottom of the processing table 1. Two second motors 10 are installed at one end of the processing table 1. The output ends of the two second motors 10 are connected to a bidirectional lead screw 11. A threaded sleeve 12 is threadedly connected to the outer wall of the bidirectional lead screw 11. A slider 13 is fixedly connected to the top of the threaded sleeve 12. A slide groove 14 is opened at the top of the processing table 1. A protective baffle 15 is fixedly connected to one end of the slider 13 through the slide groove 14. Multiple crossbars 16 are installed on the inner side of the processing table 1.

[0025] In actual use, the first motor 4 drives the lead screw 5 to rotate, so that the threaded connecting block 6 can drive the bottom grinding component 8 to move and adjust. Then, in conjunction with the power device, the grinding block is rotated to grind the polystyrene car engine hood model.

[0026] Preferably, one end of the bidirectional lead screw 11 extends through the mounting groove 9, and the through end of the bidirectional lead screw 11 can form a rotating connection structure with the inner wall of the mounting groove 9 through a bearing. The protective baffle 15 can form a sliding connection structure with the processing table 1 through the slider 13 and the slide groove 14.

[0027] In practical use, the second motor 10 drives the bidirectional lead screw 11 to rotate clockwise, so that the two threaded sleeves 12 connected to the outer wall can drive the slider 13 to move towards each other along the slide groove 14. At the same time, one end of the two threaded sleeves 12 will also drive the two protective baffles 15 to move towards each other, so that the two protective baffles 15 close and play the role of blocking flying debris. The setting of the protective baffles 15 can block the debris generated by grinding the polystyrene car engine hood model, thus improving safety.

[0028] Conversely, the second motor 10 drives the bidirectional lead screw 11 to rotate counterclockwise, so that the two threaded sleeves 12 connected to the outer wall can drive the slider 13 to move in opposite directions along the slide groove 14. At the same time, one end of the two threaded sleeves 12 will also drive the two protective baffles 15 to move in opposite directions, thereby opening the two protective baffles 15.

[0029] Preferably, the top of the processing table 1 is equipped with two connecting seats 20, and the top of the two connecting seats 20 is threaded with a threaded rod 21, and one end of the threaded rod 21 is connected to a pressure block 22.

[0031] Preferably, a chip guide slide 17 is installed at the bottom of the processing table 1, and a fixing plate 18 is installed at the bottom of the processing table 1. A groove 19 is opened on the surface of the fixing plate 18, and a collection box 23 is provided on the inner side of the groove 19. The chip guide slide 17 is located directly below the multiple crossbars 16, and the collection box 23 is located at the bottom of one end of the chip guide slide 17.

[0032] In practical use, the debris blocked by the protective baffle 15 passes through the gaps of multiple crossbars 16 as it falls, and then falls into the chip guide chute 17 directly below. Under the guidance of the chip guide chute 17, it falls into the collection box 23 for collection, which makes it convenient for staff to clean up.

[0033] Working principle: First, the end of the polystyrene car engine hood model is placed inside the two connecting seats 20. Then, by rotating the threaded rod 21, the pressure block 22 is pressed down to fix the polystyrene car engine hood model. Then, the second motor 10 drives the bidirectional lead screw 11 to rotate clockwise, so that the two threaded sleeves 12 connected to the outer wall can drive the slider 13 to move towards each other along the slide groove 14. At the same time, one end of the two threaded sleeves 12 will also drive the two protective baffles 15 to move towards each other, so that the two protective baffles 15 close and play a role in blocking flying debris. The setting of the protective baffles 15 can block the debris generated by grinding the polystyrene car engine hood model, improving safety. When the debris blocked by the protective baffles 15 falls, it passes through the gaps of multiple crossbars 16 and falls into the chip guide slide 17 directly below. Then, under the guidance of the chip guide slide 17, it falls into the collection box 23 for collection, which facilitates the cleaning by the staff.
