[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a papermaking machine with a dust collection device, comprising a papermaking machine body 1, a plurality of driving rollers 2 are installed inside the papermaking machine body 1, a dust collection box 3 is installed on the top of the papermaking machine body 1, a cover plate 5 is connected to the top hinge of the dust collection box 3, a controller 4 is installed on the right side of the papermaking machine body 1, a motor 6 is installed on the right side of the dust collection box 3, a plurality of exhaust fans 7 are installed inside the dust collection box 3, a filter element 8 is installed inside the dust collection box 3, the papermaking machine with the dust collection device also includes a first hollow box 9 installed at the front end of the dust collection box 3, and a second hollow box 10 is fixedly connected to the front end of the cover plate 5;

[0024] The fixing mechanism is installed at the front end of the dust box 3 and is used in conjunction with the second hollow box 10. The fixing mechanism is used to limit the position of the cover plate 5. The filter element 8 is the part of the vacuum cleaner responsible for filtering the air. If the filter element 8 cannot be replaced in time, the performance of the vacuum cleaner will be reduced. When replacing and cleaning the existing filter element 8, it is often necessary to disassemble the entire machine. The operation process is cumbersome and requires more time and effort. Therefore, the staff can use the fixing mechanism to quickly replace the filter element 8 inside the vacuum cleaner, thereby improving the use efficiency.

[0025] Reference Figure 2 and Figure 3As shown, in the present embodiment: the fixing mechanism includes an insertion hole 11 opened on both sides of the first hollow box 9, and a pull rod 12 is slidably connected inside the insertion hole 11, a pull plate 13 is fixedly connected to the left side of the pull rod 12, and an L-shaped clamping plate 14 is fixedly connected to the right side of the pull rod 12, and a clamping groove 15 is opened on both sides of the second hollow box 10. The staff can press the two pull rods 12 inward to make the pull rods 12 drive the L-shaped clamping plate 14 to retract inward. The L-shaped clamping plate 14 will release the limit of the clamping groove 15 on both sides of the second hollow box 10 under the drive of the pull rod 12, so that the cover plate 5 can be quickly opened, so that the staff can take out the filter element 8 inside the dust collection box 3 for cleaning, making it more convenient for the staff to use it.

[0026] Reference Figure 3 As shown, in the present embodiment: the first hollow box 9 is internally fixedly connected with a limiting rod 16, a limiting hole 17 is provided on one side of the L-shaped clip plate 14, and the surface of the limiting rod 16 is slidably connected with the inside of the limiting hole 17. By fixing the limiting rod 16 inside the first hollow box 9 and providing the limiting hole 17 on one side of the L-shaped clip plate 14, a limiting relationship is formed between the L-shaped clip plate 14 and the limiting rod 16, so that the staff can move the L-shaped clip plate 14 stably.

[0027] Reference Figure 3 As shown, in the present embodiment: the inner wall of the L-shaped clip plate 14 is fixedly connected with a reset spring 18. When the staff presses the pull rod 12 inward, the reset spring 18 inside the L-shaped clip plate 14 will accumulate force inward. When the staff releases the pull rod 12, the reset spring 18 will generate force on both sides, causing the L-shaped clip plate 14 to rebound quickly outward. At the same time, the force generated by the reset spring 18 can make the staff more stable when fixing the cover plate 5.

[0028] Reference Figure 4 As shown, in this embodiment: hollow blocks 19 are fixedly connected to both sides of the inner cavity of the dust box 3, an ejection spring 20 is fixedly connected to the bottom of the inner cavity of the hollow block 19, and a top plate 21 is fixedly connected to the top of the ejection spring 20. When the staff opens the cover 5, the ejection spring 20 generates an upward thrust on the top plate 21, thereby quickly ejecting the filter element 8 from the inside of the dust box 3, thereby allowing the staff to replace the filter element 8 more quickly.

[0029] Reference Figure 5 As shown, in this embodiment: a limiting groove 22 is opened on the top of the dust box 3, the number of the limiting grooves 22 is two, and the limiting blocks 23 are fixedly connected on both sides of the filter element 8. By opening the limiting groove 22 on the top of the dust box 3 and fixing the limiting blocks 23 on both sides of the filter element 8, the filter element 8 is prevented from shaking when being taken out from the dust box 3.

[0030] Reference Figure 2 As shown, in this embodiment: a sealing gasket 24 is installed on the top of the dust box 3. By installing the sealing gasket 24 on the top of the dust box 3, when the cover 5 is in a closed state, the dust box 3 is in a sealed state to prevent the absorbed gas and impurities from leaking from both sides.

[0031] The practical working principle of the present invention: the filter element 8 is the part of the vacuum cleaner responsible for filtering the air. If the filter element 8 cannot be replaced in time, the performance of the vacuum cleaner will be reduced. When replacing and cleaning the existing filter element 8, it is often necessary to disassemble the entire machine. The operation process is cumbersome and requires more time and effort. Therefore, the staff can use the fixing mechanism to quickly replace the filter element 8 inside the vacuum cleaner, thereby improving the use efficiency. The staff can press the two pull rods 12 inward to make the pull rods 12 drive the L-shaped clamping plate 14 to retract inward. The L-shaped clamping plate 14 will release the limit with the clamping grooves 15 on both sides of the second hollow box 10 under the drive of the pull rods 12, so that the cover plate 5 can be quickly opened, so that the staff can take out the filter element 8 inside the dust box 3 for cleaning, making it more convenient for the staff to use it. The limiting rod 16 is fixedly connected to the inside of the first hollow box 9, and a limiting hole 17 is opened on one side of the L-shaped clamping plate 14, so that the L-shaped clamping plate 14 and the limiting rod 16 form a limiting relationship. When the staff member releases the pull rod 12, the return spring 18 will generate force on both sides, causing the L-shaped clip plate 14 to rebound quickly outward. At the same time, the force generated by the return spring 18 can make the staff more stable when fixing the cover 5. When the staff member opens the cover 5, the ejection spring 20 and the top plate 21 generate an upward force to quickly eject the filter element 8 from the inside of the dust box 3, so that the staff can replace the filter element 8 more quickly. By providing a limiting groove 22 at the top of the dust box 3 and fixing the limiting blocks 23 on both sides of the filter element 8, the filter element 8 is prevented from shaking when it is taken out of the dust box 3. By installing a sealing gasket 24 on the top of the dust box 3, the cover 5 can be in a closed state, and then the dust box 3 is in a sealed state to prevent the absorbed gas and impurities from leaking from both sides.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
