[0030] As Figures 1 to 3 shown, this embodiment provides a quick-change filter element dust collection box, which includes a dust collection box body 1. The dust collection box body 1 is connected to an input pipe 2 and an air suction pipe 3. A hollow cylindrical filter element 4 is installed in the dust collection box body 1. One end inner wall of the cylindrical filter element 4 is sleeved on a cylindrical card seat 401. The cylindrical card seat 401 is connected to the input end of the air suction pipe 3. The other end of the cylindrical filter element 4 is coaxially and closely attached with an airtight pressing plate 6. The diameter of the airtight pressing plate 6 is larger than the inner diameter of the cylindrical filter element 4. A telescopic push rod 601 is connected behind the airtight pressing plate 6.

[0031] During the operation of the equipment, the dust generated by the plate cutting enters the dust collection box body 1 through the input pipe 2. Then, the air in the dust collection box body 1 is extracted under the action of equipment such as a suction fan connected to the air suction pipe 3. The dust in the air is intercepted on filter materials such as the cylindrical filter element 4, achieving the dust collection and filtering effect. Specifically, under the action of the airtight pressing plate 6 and the air suction pipe 3 connected to the cylindrical card seat 401, the air in the dust collection box body 1 can only be output after passing through the cylindrical filter element 4. Therefore, the dust in the air will be intercepted on the cylindrical filter element 4.

[0032] In addition, when replacing the cylindrical filter element 4, only need to pull the telescopic push rod 601 backward and then pull the cylindrical filter element 4 away from the cylindrical card seat 401, which is fast and convenient. Conversely, inserting the cylindrical filter element 4 into the cylindrical card seat 401 and pressing the telescopic push rod 601 forward can complete the installation of the cylindrical filter element 4.

[0033] The cylindrical holder 401 is arranged on the inner side wall of the dust collecting box body 1, and the inner wall of one end of the cylindrical filter element 4 is horizontally sleeved on the cylindrical holder 401, and a horizontal support plate 7 is arranged below the cylindrical filter element 4. The horizontal cylindrical filter element 4 can be quickly positioned and installed in place by using the horizontal support plate 7, which can increase the replacement speed of the filter element.

[0034] The telescopic top rod 601 is movably sleeved in the horizontal sleeve 602, and the end of the telescopic top rod 601 is hinged with a switch handle 603 through a rotating shaft. The horizontal sleeve 602 can limit the telescopic top rod 601 and the airtight pressing plate 6, ensuring that the airtight pressing plate 6 can lock the cylindrical filter element 4 when in the forward state. The switch handle 603 makes it convenient for the staff to manually move the telescopic top rod 601.

[0035] The dust collecting box body 1 is provided with a dust collecting bag 5, and the opening of the dust collecting bag 5 is sleeved on the output end of the input pipe 2. The dust collecting bag 5 sleeved on the input pipe 2 is easy to install and remove, and can cooperate with the cylindrical filter element 4 to improve the filtering effect.

[0036] The dust collecting box body 1 is provided with a support mesh cover 103, and the dust collecting bag 5 is placed in the support mesh cover 103. The hard support mesh cover 103 provides support for the dust collecting bag 5, preventing the dust collecting bag 5 from contacting the inner wall of the dust collecting box body 1, resulting in a decrease in the smoothness of the airflow passing through the bag.

[0037] The front end of the dust collecting box body 1 is open, and the front end of the dust collecting box body 1 is connected with a box body door 101 through a door hinge 102. The box body door 101 of the hinge switch facilitates the staff to quickly open and close the dust collecting box body 1.

[0038] A quick release buckle 104 is connected to the rotating shaft on the opposite side of the door panel hinge 102 on the box body door 101, and a quick release card seat 105 is provided at the front end of the dust collecting box body 1 corresponding to the quick release buckle 104, and the quick release buckle 104 is movably buckled in the quick release card seat 105. The quick release buckle 104 cooperates with the quick release card seat 105 to ensure that the box body door 101 is opened and closed with both speed and stability.

[0039] The front opening of the dust collecting box body 1 is surrounded by an airtight gasket 8, and the inner side of the box door 101 is provided with a gasket slot 801 corresponding to the airtight gasket 8. The airtight gasket 8 cooperates with the gasket slot 801 to improve the airtightness of the dust collecting box body 1, and avoids air leakage from the gap of the dust collecting box body 1, which leads to a decrease in the filtering effect.

[0040] A door opening limit block 9 is provided at the rear side of the door hinge 102 of the door panel. The door opening limit block 9 protrudes out of the outer side of the dust collection box body 1. The door opening limit block 9 can prevent the box body door 101 from being opened excessively, resulting in structural damage. In addition, in this embodiment, the door opening limit block 9 is set in an L shape, so that the opening angle of the box body door 101 is limited to 90°. While the opening angle is sufficient for replacing the filter material, it is convenient for the staff to grasp the box body door 101 to close, which conforms to ergonomics.

[0041] An air pressure detection module 10 is connected to the inner side of the suction pipe 3. The air pressure detection module 10 includes a display component. The air pressure detection module 10 containing a display component can adopt a pressure gauge product on the market, which is convenient for the staff to monitor the dust suction air pressure at any time. So as to remind the staff to replace the filter material in time when there is too much dust and insufficient pressure inside the dust collection box body 1. It is worth mentioning that a digital display pressure gauge with an alarm function can be used for automatic alarm.

[0042] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. That is, all equivalent changes and modifications made according to the scope of this application should still fall within the scope covered by the present invention.
