Description

Technical Field

[0002] Cutting is an indispensable step in the processing of medical accessories. However, cutting operations are often accompanied by the generation of large amounts of smoke and dust, which not only pollutes the working environment but also poses a threat to the health of operators.

[0003] A search revealed a Chinese patent with publication number CN208495942U, which provides a medical parts dust removal and cutting device. A muffler reduces cutting noise, while a vacuum cleaner collects debris from the workbench surface and collects it in a dust bag. This device is energy-efficient and environmentally friendly, reduces health hazards to workers, and provides a comfortable working environment. Anti-slip mats improve processing stability, and counterweights are placed inside the storage box to increase overall weight, preventing displacement of the base during processing and accidents such as injury from shaking or tilting, improving safety. A cleaning brush facilitates cleaning of the workbench, keeping it clean and tidy.

[0004] However, during use, it was found that although the device collects debris on the surface of the workbench through a vacuum cleaner, during the cutting operation, the smoke and dust tend to spread everywhere and are not limited to the surface of the workbench. A single vacuuming method is difficult to fully capture and collect all the generated smoke and dust, resulting in some smoke and dust still escaping into the air, continuing to pollute the working environment and endangering the health of the operators. Therefore, a more efficient and comprehensive dust removal device is needed to deal with the smoke and dust problem during the cutting process of medical accessories. Utility Model Content

[0025] 4. After the cylinder is installed, engage the shift block with the cylinder through the groove and secure it with fasteners. To adjust the blowing direction of the blowing assembly, use the piston rod of the cylinder to push the support up and down, so that the support drives the pin to rotate the shift block. The pin slides along the shift block through the through hole, driving the cylinder and the air outlet slot to rotate together, thereby adjusting the blowing direction.

[0045] Working principle: First, place the medical accessories to be cut between the two clamping blocks 10 on the cutting table 1. The output shaft of the servo motor 17 drives the bidirectional screw 15 to rotate. The bidirectional screw 15 pushes the L-shaped block 14 to move along the axial direction of the bidirectional screw 15, thereby driving the clamping block 10 to slide on the top surface of the cutting table 1 to clamp and fix the medical accessories. The medical accessories are cut by the cutting machine body 2. The smoke generated during the cutting process forms a negative pressure inside the dust hood 4 through the activation of the dust suction fan 8. After the smoke enters the suction groove 5 of the dust hood 4 through the first dust suction groove 6 and the second dust suction groove 7, it is sucked into the dust collecting bag 9 by the dust suction fan 8 for collection, completing the collection of smoke and dust and improving the dust collection range.

[0046] In order to further improve the dust removal effect, the cylinder 1101 and the limiting ring 1106 are installed to the top surface of the cutting table 1 through the circular groove 18 and the limiting groove 1105, and the arc-shaped clamping ring 1107 is clamped with the cylinder 1101 and the limiting ring 1106 for positioning and installation. After the installation is completed, the external air is sucked and transported to the conveying groove 1102 of the cylinder 1101 through the air inlet fan 1104, and blown out through the air outlet groove 1103, so that the air outlet groove 1103 blows the air in the direction of the first dust suction groove 6 and the second dust suction groove 7, thereby improving the air flow effect, making it easier to be captured by the dust hood 4, reducing the occurrence of dust escape, and improving the dust removal effect of smoke and dust;

[0047] The cutting machine body 2 cuts through the cutting groove 3. After some cutting debris enters the interior of the cutting table 1 through the cutting groove 3, it slides to the discharge port 12 and is discharged to the outside, which facilitates the collection of the cutting debris.

[0048] Example 2

[0049] like Figure 1 , Figure 2 and Figure 6As shown, on the basis of Example 1, a groove 1108 is opened on the side wall of the other end of the cylinder 1101, a shift block 1109 is inserted into the groove 1108, the outer wall of the shift block 1109 is threadedly connected to the fastener 1110 through a threaded hole, and the cylinder 1101 is threadedly connected to the fastener 1110 through the threaded hole; the shift block 1109 is clamped to the cylinder 1101 through the groove 1108 and fixed by the fastener 1110.

[0051] When in use, after the cylinder 1101 is installed, the shift block 1109 is clamped with the cylinder 1101 through the groove 1108 and fixed with the fastener 1110. When the blowing direction of the blowing assembly 11 needs to be adjusted, the piston rod of the cylinder 1114 pushes the support 1113 up and down, so that the support 1113 drives the pin 1112 to push the shift block 1109 to rotate, and the pin 1112 slides along the shift block 1109 through the through hole 1111, driving the cylinder 1101 and the air outlet groove 1103 to rotate together, thereby adjusting the blowing direction, so that the blowing direction can be accurately adjusted according to the needs of the cutting operation, thereby improving the pertinence and efficiency of dust removal;
