It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0026] In the present utility model, unless otherwise stated, directional words contained in terms such as "up, down, left, right, front, back, inside, outside" merely represent the orientation of the terms in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0027] See also Figure 1-5The air filter paper cutting device shown in the figure comprises a bottom plate 1 and side plates 2 fixedly connected to both sides of the bottom plate 1, wherein the side plates 2 are provided with rectangular windows 8, wherein a vertically sliding movable plate 14 is provided in the rectangular window 8, wherein a crossbeam 11 is fixedly connected to the side plates 2, wherein a first driving mechanism connecting the movable plates 14 is installed on the crossbeam 11, wherein a plurality of transmission roller groups are arranged between the two movable plates 14, wherein the transmission roller group comprises a pressure roller 4 whose two ends are rotatably arranged on the movable plates 14 and a pressure roller 4 whose two ends are rotatably arranged on the bottom plate 1 The bottom plate 1 is provided with a rectangular hole 22 for accommodating the bearing roller 5, the upper surface of the bearing roller 5 is flush with the upper surface of the bottom plate 1, the lower surface of the pressing roller 4 is lower than the lower surface of the movable plate 14, the outer ends of the plurality of pressing rollers 4 are linked and connected to rotate in the same direction and are connected to a second driving mechanism, a cutting groove 23 is provided between two adjacent bearing rollers 5 at the ends on the bottom plate 1, a cutting knife 6 is provided above the cutting groove 23, and a third driving mechanism connected to the cutting knife 6 is provided between the two side plates 2.

[0028] Through the implementation of the above technical solution, one end of the air filter paper cutting device is set as the inlet of the filter paper 21, and the other end is set as the outlet of the filter paper 21. When the air filter paper 21 needs to be cut, one end of the filter paper 21 is inserted from the inlet of the filter paper 21 between the supporting roller 5 and the pressing roller 4 in the transmission roller group at the inlet position, and then the height of the pressing roller 4 is adjusted by the first driving mechanism so that the height of the pressing roller 4 can match the thickness of the filter paper 21 and the filter paper 21 can be transmitted by rolling. As the transmission proceeds, the filter paper 21 is transmitted to the subsequent transmission roller group until it is transmitted to the last transmission roller group. When the transmission length of the filter paper 21 reaches the cutting position, the cutter 6 is driven by the third driving mechanism to move down quickly to cut the filter paper 21 into sections. Since the movable plate 14 can carry the pressing roller 4 for height adjustment, the interval between the pressing roller 4 and the carrying roller 5 can be adjusted, so that filter papers 21 of different thicknesses can be transmitted, and the pressure of the filter paper 21 being squeezed can be adjusted, so that the filter paper 21 can be better transmitted and then cut. By setting the upper surface of the carrying roller 5 to be flush with the upper surface of the bottom plate 1, and setting the lower surface of the pressing roller 4 to be lower than the lower surface of the movable plate 14, the pressing roller 4 and the carrying roller 5 can better cooperate to transmit the filter paper 21.

[0029] In this embodiment, the bottom plate 1 is provided with a limiting groove 3 extending along its length direction and having a depth less than the thickness of the filter paper 21 to be cut, and both ends of the cutting groove 23 are arranged outside the limiting groove 3. Through such an arrangement, the filter paper 21 to be transported is limited to the left and right, and in addition, the depth of the limiting groove 3 is set to be less than the thickness of the filter paper 21 to be cut, which does not affect the transmission of the filter paper 21.

[0030] In this embodiment, in order to further provide a first driving mechanism, the first driving mechanism includes a transverse plate 12 and a longitudinal plate 9 fixed to both ends of the transverse plate 12, and the bottom sides of both ends of the longitudinal plate 9 are fixed with a first polished rod 16 that slides into the rectangular window 8 and connects the movable plate 14, and a first cylinder 13 connected to the crossbeam 11 is installed on the transverse plate 12. The transverse plate 12 and the longitudinal plate 9 are controlled to move vertically by the extension and contraction of the first cylinder 13, so that the movable plates 14 on both sides are driven to move synchronously under the traction of the first polished rod 16, thereby driving the multiple pressing rollers 4 to move vertically synchronously to adjust their positions.

[0031] In this embodiment, a plurality of second light rods 18 are arranged in the rectangular window 8, and a light hole is arranged on the movable plate 14 to slide with the second light rods 18. The plurality of second light rods 18 and the sliding of the light hole can guide the movable plate 14 vertically.

[0032] In this embodiment, in order to further provide a second driving mechanism, the second driving mechanism includes a gear 15 sleeved on the outer end of the pressure roller 4, a plurality of the pressure rollers 4 are sleeved with a gear sleeve 17, the inner side of the gear sleeve 17 is meshed with each of the gears 15, and the outer end of one of the pressure rollers 4 is connected to a driving motor 20. Figure 2 As shown, the driving motor 20 is arranged on the side opposite to the gear sleeve 17. The driving motor 20 drives one of the pressure rollers 4 to rotate, and then the gear sleeve 17 is driven to rotate under the rotation of the gear 15 on the pressure roller 4, and the rotation of the gear sleeve 17 drives other gears 15 to rotate, thereby driving other pressure rollers 4 to rotate and transmit the filter paper 21.

[0033] In this embodiment, in order to further provide a third driving mechanism, the third driving mechanism includes a door frame 7 spanned between the two side panels 2, and a second cylinder 10 connected to the upper end of the cutter 6 is provided on the door frame 7. When cutting, the cutter 6 is driven by the second cylinder 10 to move vertically downward to cut the filter paper 21, and the provided cutting groove 23 is used to extend into the lower end of the cutter 6 during cutting.

[0034] In this embodiment, in order to further provide a method for installing the load-bearing roller 5 , a bearing seat 19 for installing the load-bearing roller 5 is installed at both ends of the rectangular hole 22 on the bottom side of the bottom plate 1 .

[0035] In this embodiment, the edge of the rectangular hole 22 facing the outlet of the filter paper 21 is set as a round chamfer 24. Through such a setting, the filter paper 21 is prevented from being squeezed with the side wall of the rectangular hole 22 on the side of the rectangular hole 22 facing the outlet of the filter paper 21, thereby preventing the filter paper 21 from being stuck, and the slight inclination of the end of the filter paper 21 plays a role in sliding back.
