[0033] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0034] Example 1

[0035] Please refer to Figure 1-4, this embodiment provides a filter element tape sticking and cutting device, which mainly includes a frame 1, a filter element positioning mechanism 2, a tape sticking mechanism 4 and a tape cutting mechanism 5. Among them, the frame 1 has a top plate 11, and the top plate 11 is used to fix the lifting module 12. The lifting module 12 in this embodiment is an electric cylinder, and the output end of the electric cylinder is vertically arranged downward to control the lifting and lowering of the tape sticking mechanism 4. Furthermore, a transverse movement module 13 is provided on the moving end of the lifting module 12, and the tape sticking mechanism 4 is fixed to the moving end of the transverse movement module 13. The moving end of the transverse movement module 13 moves along the positioning direction of the filter element 3. The transverse movement module 13 is a screw module. By adjusting the horizontal position of the tape sticking mechanism 4, the offset of the tape under the filter elements 3 of different diameters is compensated, and the sticking position is adjusted, so as to ensure the quality of the tape sticking.

[0036] The filter element positioning mechanism 2 is arranged on both sides of the bottom of the frame 1, and is used to position the filter element 3 from both sides and drive the filter element 3 to rotate; in this embodiment, the filter element positioning mechanism 2 specifically includes a first positioning cylinder 21 and a second positioning cylinder 22 arranged on both sides of the frame 1, and the output end of the first positioning cylinder 21 is provided with a first positioning top 23, and the output end of the second positioning cylinder 22 is provided with a second positioning top 24. The first positioning cylinder 21 and the second positioning cylinder 22 drive the first positioning top 23 and the second positioning top 24 to move relative to each other to clamp the center tube of the filter element 3. The first positioning top 23 is installed on the bearing seat and can rotate freely. The second positioning top 24 is driven by the positioning rotation servo 25, thereby driving the filter element 3 to rotate.

[0037] The tape sticking mechanism 4 is lifted and lowered above the filter element positioning mechanism 2, and includes a fixed plate 41 and a reel 42. The fixed plate 41 is fixed on the transverse module 13, and the reel 42 is fixed on the fixed plate 41. One end of the fixed plate 41 is provided with a mounting plate 43, and the other end of the mounting plate 43 is provided with a glue pressing cylinder 44. The output end of the glue pressing cylinder 44 is provided with a glue pressing roller 45. The tape is discharged from the reel 42 and passes through a transition roller 46. Under the action of the glue pressing roller 45, it is adhered to the surface of the filter element 3, and the filter element 3 is subjected to the tape sticking operation in coordination with the self-rotation of the filter element 3.

[0038] The tape cutting mechanism 5 is arranged on the tape applying mechanism 4 and is used to cut the tape after the tape is applied. The tape cutting mechanism 5 includes a moving cylinder 51 fixed on the mounting plate 43. A cylinder scissors 52 are fixed to the moving end of the moving cylinder 51, and the cylinder scissors 52 face the side of the tape 6. After the tape is applied, the moving cylinder 51 drives the cylinder scissors 52 to move on the side of the tape 6 until the opened cylinder scissors 52 can cut the tape 6.

[0039] Example 2

[0040] This embodiment is formed on the basis of the embodiment 1, by providing a rotating plate 47 and a glue-applying roller 48 at the end of the rotating plate 47, the adhesive tape 6 is fed, and the adhesive tape 6 can be pressed before cutting to prevent the adhesive tape from falling off. Specifically:

[0041] A rotating plate 47 is axially connected to the fixed plate 41, and the axial connection point of the rotating plate 47 is away from the side of the mounting plate 43. A glue feeding cylinder 49 is axially connected to the fixed plate 41, and the output shaft of the glue feeding cylinder 49 is axially connected to the rotating plate 47. The rotating plate 47 rotates around its axial connection point under the action of the glue feeding cylinder 49, thereby moving away from or close to the filter element 3 to be taped.

[0042] The other end of the rotating plate 47 is connected to a glue sticking roller 48 through a rotating shaft 481. A pressing block 483 is provided next to the glue sticking roller 48. The pressing block 483 has an arc surface that fits the glue sticking roller 48. Please refer to Figure 4 , 5 The central axis of the rotating shaft 481 is connected to the end of the rotating plate 47, and a spring 482 is fixed to the other side of the rotating shaft 481. When the spring 482 is set above the rotating shaft 481, the spring 482 adopts a tension spring. The spring 482 and the rotating plate 47 generate a force to press the glue roller 48 to the side of the pressing block 483, which can press the tape 6 between the glue roller 48 and the pressing block 483. After the tape is applied, the tape 6 can be pressed and then cut to prevent the tape from falling off, thereby improving the quality of the tape application. In the initial state, the force of the expanded spring 482 presses the glue roller 48 onto the pressing block 483. When in use, the glue feeding cylinder 49 drives the glue roller 48 downward to fit the surface of the filter element 3. The glue feeding cylinder 49 continues to press downward, so that the rotating shaft 481 compresses the spring 482 to make the glue roller 48 leave the pressing block 483, so that the tape 6 can be wound; after the tape is pasted, the glue feeding cylinder 49 is reset, and there is no longer any force between the glue roller 48 and the filter element 3. The glue roller 48 is pressed against the pressing block 483 under the action of the tension of the spring 482 to prevent the tape 6 from falling off when the tape is cut.

[0043] Furthermore, the glue pressing roller 45, the glue applying roller 48, the transition roller 46 and the unwinder 42 are in the same plane, which can ensure the flatness of the adhesive tape as much as possible.

[0044] The working principle of this embodiment:

[0045] First, the filter element 3 is moved between the filter element positioning mechanism 2, the first positioning tip 23 and the second positioning tip 24 move relative to each other to clamp the central tube of the filter element 3, and the filter element 3 is positioned. The transverse module 13 and the lifting module 12 are started, and the tape sticking mechanism 4 is moved to a suitable position for sticking the tape. The glue feeding cylinder 49 is pressed down, and the tape 6 is pre-sticked to the surface of the filter element 3 through the glue sticking roller 48.

[0046] Then the positioning rotary servo 25 drives the filter element 3 to rotate. After a certain angle, the lifting module 12 rises. At this time, the positioning rotary servo 25 continues to rotate until the tape 6 is attached to a specified number of circles and the rotation stops. The glue feeding cylinder 49 is lifted up, and at the same time, the moving cylinder 51 drives the cylinder scissors 52 to move. After the tape 6 is cut, the moving cylinder 51 drives the tape cutting mechanism 5 to retreat.

[0047] Then the glue pressing cylinder 44 is started to press the remaining tape 6 onto the surface of the filter element 3, and the positioning rotation servo 25 rotates to drive the filter element 3 to rotate again to press the tape 6 tightly; finally, the glue pressing cylinder 44 retracts, the lifting module 12 is lifted, the transverse module 13 returns to zero, and the filter element positioning mechanism 2 releases the product, completing the tape sticking operation of the filter element 3.
