Technical Field
[0001] This utility model relates to the field of industrial dust collection equipment technology, specifically a dust collection device for a high-speed vertical machining center that prevents clogging. Background Technology
[0002] The use of high-speed vertical machining centers (CNC), especially in the cutting of wood or composite materials, generates a large amount of dust. As the cutting speed increases, the amount of dust generated per unit time also increases, posing a serious threat to the occupational health environment in the workshop.
[0003] In the dust collection system of high-speed vertical machining centers, filter bags play a crucial role. They are responsible for capturing and collecting dust generated during the cutting process, thereby maintaining clean air in the workshop. However, the filter bags inside traditional dust collection systems are prone to clogging after prolonged use. When the filter bags are clogged, their air permeability is greatly reduced, resulting in weakened suction power and an inability to effectively suck up dust. This not only reduces dust collection efficiency but may also cause dust to scatter throughout the workshop, posing a threat to the health of operators. Furthermore, replacing and cleaning the filter components in conventional dust collection systems is quite troublesome, often leading to prolonged downtime of the machining center. The replacement costs are too high, affecting the normal use of the equipment and overall efficiency.
[0004] Therefore, a dust extraction device for a high-speed vertical machining center that prevents clogging is provided to overcome the above-mentioned defects. Utility Model Content

A movable plate is threaded onto the outer wall of the bidirectional lead screw, and an inner limiting block is fixedly connected to the bottom of the movable plate. An outer limiting block, adapted to the inner limiting block, is installed at the edge of the inner wall of the coupling interface.
[0007] Furthermore, the specific number of the outer limiting block, inner limiting block, and moving plate is two, and the two moving plates are simultaneously threadedly connected to the outer wall of the bidirectional lead screw, and are arranged symmetrically as a whole.
[0008] Furthermore, a guide rod is fixedly installed on the inner wall of the interface, and the movable plate is slidably sleeved on the outer wall of the guide rod.
[0009] Furthermore, a rotatable rotating block is provided on the outer wall of the interface, and the rotating block is fixedly connected to the worm gear.

[0024] 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.
[0025] Example 1
[0026] See Figure 1-5 A dust collection device for a high-speed vertical machining center with anti-clogging features includes a dust collection tank body 4, a dust collection pipe 5, a dust collection head 6, and a drive chamber 8. A removable filter bag 7 is installed on the top surface of the inner wall of the dust collection tank body 4, and the filter bag 7 is located directly above the drive chamber 8. A coupling interface 10 is fixedly installed at the middle position of the top surface of the inner wall of the dust collection tank body 4. A rotatable worm gear 15 is installed on the inner wall of the coupling interface 10. A rotatable bidirectional lead screw 14 is installed on the inner wall of the coupling interface 10. A worm wheel 17 is fixedly installed at the middle position of the outer wall of the bidirectional lead screw 14. The worm wheel 17 meshes with the worm gear 15. A moving plate 13 is threadedly connected to the outer wall of the bidirectional lead screw 14. An inner limit block 12 is fixedly connected to the bottom of the moving plate 13. An outer limit block 11 adapted to the inner limit block 12 is installed at the edge of the inner wall of the coupling interface 10.
[0027] Furthermore, there are two outer limit blocks 11, two inner limit blocks 12, and two moving plates 13. The two moving plates 13 are threadedly connected to the outer wall of the bidirectional lead screw 14 and are arranged symmetrically. By setting the two moving plates 13 to be threadedly connected to the outer wall of the bidirectional lead screw 14 and arranged symmetrically, the bidirectional lead screw 14 can drive the two moving plates 13 to move towards each other or relative to each other during rotation.
[0028] Furthermore, a guide rod 9 is fixedly installed on the inner wall of the interface 10, and the movable plate 13 is slidably sleeved on the outer wall of the guide rod 9. By setting the guide rod 9 and the movable plate 13 being slidably sleeved on the outer wall of the guide rod 9, the movement of the movable plate 13 is guided and will not easily deviate.
[0029] In addition, a rotatable rotating block 16 is provided on the outer wall of the interface 10. The rotating block 16 is fixedly connected to the worm gear 15. The fixed connection between the rotating block 16 and the worm gear 15 allows the user to rotate the rotating block 16 to drive the worm gear 15 to rotate. A base plate 1 is fixedly installed at the bottom of the vacuum cleaner body 4. Multiple rotatable casters 2 are installed at the bottom of the base plate 1. The base plate 1 and the casters 2 facilitate the movement of the entire device. A push rod 3 is fixedly installed on the top surface of the base plate 1. The push rod 3 allows the user to push the push rod 3 more easily.
[0030] It should be noted that the filter bag 7 includes a filter cloth 71 and a connecting ring 72. The connecting ring 72 is located at the top of the filter cloth 71. By setting the connecting ring 72 at the top of the filter cloth 71, the filter bag 7 can be stably fixed with the cooperation of the outer limiting block 11 and the inner limiting block 12.
[0031] It should also be noted that the front end of the vacuum cleaner body 4 is hinged with an arc-shaped cover plate, and a handle is fixedly installed on the outer wall of the arc-shaped cover plate. By setting the front end of the vacuum cleaner body 4 to be hinged with an arc-shaped cover plate and changing the fixed handle at the front end, the user can replace the filter bag 7 by opening the arc-shaped cover plate when it is necessary, which further speeds up the replacement of the filter bag 7.
[0032] In addition, a negative pressure fan is installed in the drive chamber 8 installed on the bottom inner wall of the main body 4 of the dust collection tank to provide power for the overall operation of the device.
[0033] In practice, to ensure that the device does not encounter problems during use, the user needs to frequently replace the filter bag 7.
[0034] In this utility model, when the user needs to replace the filter bag 7, they can directly open the arc-shaped cover hinged to the front side of the vacuum cleaner body 4, and then rotate the rotating block 16. After the rotating block 16 rotates, it will drive the worm gear 15 to rotate. The worm gear 15 meshes with the worm wheel 17, and the worm wheel 17 is fixedly installed on the outer wall of the bidirectional lead screw 14. Therefore, after the rotating block 16 is rotated by the user, the bidirectional lead screw 14 will also rotate synchronously. During the rotation of the bidirectional lead screw 14, the two moving plates 13 will drive the two inner limit blocks 12 to move towards each other or relative to each other at the same time. When moving towards each other, the filter bag 7 loses the restriction of the inner limit block 12 and the outer limit block 11, and the filter bag 7 can be easily removed. Similarly, when it is necessary to fix the filter bag 7, the docking ring 72 can be placed between the inner limit block 12 and the outer limit block 11, and then the rotating block 16 is reversed to drive the two inner limit blocks 12 to move relative to each other, so that the filter cloth 71 is fixed again, thus completing the replacement of the filter bag 7.
[0035] By setting up a bidirectional lead screw 14, a worm gear 15, and a worm wheel 17, the two inner limit blocks 12 can be quickly driven by the user to move relative to or towards each other, allowing the user to quickly replace the filter bag 7. At the same time, by utilizing the cooperative characteristics of the worm gear 15 and the worm wheel 17, the device will not easily reverse after adjustment, making the filter bag 7 more stable.
[0036] Working principle: In order to ensure that the device does not have any problems during use, the user needs to replace the filter bag 7 frequently.
[0037] In this utility model, when the user needs to replace the filter bag 7, they can directly open the arc-shaped cover hinged to the front side of the vacuum cleaner body 4, and then rotate the rotating block 16. After the rotating block 16 rotates, it will drive the worm gear 15 to rotate. The worm gear 15 meshes with the worm wheel 17, and the worm wheel 17 is fixedly installed on the outer wall of the bidirectional lead screw 14. Therefore, after the rotating block 16 is rotated by the user, the bidirectional lead screw 14 will also rotate synchronously. During the rotation of the bidirectional lead screw 14, the two moving plates 13 will drive the two inner limit blocks 12 to move towards each other or relative to each other at the same time. When moving towards each other, the filter bag 7 loses the restriction of the inner limit block 12 and the outer limit block 11, and the filter bag 7 can be easily removed. Similarly, when it is necessary to fix the filter bag 7, the docking ring 72 can be placed between the inner limit block 12 and the outer limit block 11, and then the rotating block 16 is reversed to drive the two inner limit blocks 12 to move relative to each other, so that the filter cloth 71 is fixed again, thus completing the replacement of the filter bag 7.
[0038] By setting up a bidirectional lead screw 14, a worm gear 15, and a worm wheel 17, the two inner limit blocks 12 can be quickly driven by the user to move relative to or towards each other, allowing the user to quickly replace the filter bag 7. At the same time, by utilizing the cooperative characteristics of the worm gear 15 and the worm wheel 17, the device will not easily reverse after adjustment, making the filter bag 7 more stable.
