[0033] Figures 1 to 6 are drawings of the present invention.

[0034] This embodiment provides a shaping device for filter element production, see Figures 1 to 3 , including a frame 10, a power member 11 arranged on the frame 10, and a shaping mold 12 arranged at the power output end of the power member 11. The shaping mold 12 is used to shape the end of the filter element to make the subsequent processing steps more convenient, improve efficiency and reduce the error rate. The power member 11 drives the shaping mold 12 to move so that the end of the filter element is deformed according to the shape of the shaping mold 12. In this embodiment, the power member 11 moves downward, and the shaping mold 12 squeezes the filter element to deform the end of the filter element.

[0035] The frame 10 is also provided with a positioning block 13. The positioning block 13 is arranged below the shaping mold 12 to position the filter element so that the shaping mold 12 can be accurately aligned with the filter element when it descends.

[0036] Preferably, there are at least two positioning blocks 13, and the two positioning blocks 13 are aligned with the upper end and the lower end of the filter element, so that the positioning is more accurate.

[0037] Preferably, the contour of the positioning block 13 matches the outer contour of the filter element. After the positioning block 13 is installed, the filter element is placed on the workbench 14 and positioned close to the positioning block 13, and then the shaping mold 12 can be lowered to shape the filter element.

[0038] A workbench 14 is provided below the shaping mold 12. A positioning block 13 is provided between the workbench 14 and the shaping mold 12. The workbench 14 is provided on the top of the frame 10.

[0039] Specifically, the power member 11 is fixed to a mounting plate 15. The mounting plate 15 is connected to the top of the workbench 14 through a supporting column 16. The shaping mold 12 is arranged on a side of the mounting plate 15 facing the workbench 14.

[0040] The positioning block 13 is fixed above the workbench 14 via a connecting column 17 and is located below the shaping mold 12 .

[0041] Preferably, the power member 11 is a cylinder.

[0042] In other embodiments, the power member 11 includes a motor and a screw member. The shaping die 12 is fixedly connected to a nut of the screw member.

[0043] For details, please refer to Figure 3 The shaping mold 12 is a circular structure. The shaping mold 12 is provided with a groove 121 for squeezing the filter element. The groove 121 is provided with an inclined surface 122 for squeezing the outside of the filter element so as to close the outside of the filter element. The inclined surface 122 is inclined toward the center of the circle so as to close the outer protective net.

[0044] The middle of the groove 121 is provided with a protrusion 123 for squeezing the inner cavity of the filter element so as to expand the inner cavity of the filter element. Similarly, the outer periphery of the protrusion 123 is also provided with an inclined surface so as to expand the inner protection net.

[0045] Preferably, the power member 11 is a cylinder, which is connected to an air source via a switch valve 18 .

[0046] The shaping mold 12 closes the protective net on the outside of the filter element, generally closing the portion of the external protective net that is higher than the filter paper, and the closing position starts from a position 15mm to 22mm away from the top of the external protective net.

[0047] The maximum distance that the outer protective net closes inwards is 2 to 6 mm, and the maximum distance that the inner protective net expands outwards is 2 to 6 mm.

[0048] In other embodiments, the bending angle of the outer protective net closing inward is 2 to 10°, and similarly, the bending angle of the inner protective net expanding outward is also 2 to 10°.

[0049] After shaping (expanding or closing) the inner and outer protective nets of the filter element, the inner and outer protective nets can fix the filter paper, and the filter paper will not loosen during transportation or the next process. More importantly, after shaping at both ends of the filter element, it is convenient to insert it into the injection mold. Since the deformation after shaping (2 to 3mm or 2 to 10°) is small, there is no leakage during injection, which can improve production efficiency and production quality.

[0050] A filter element production process, please refer to Figures 3 to 6 , including the following steps:

[0051] Step 1: Put the outer protective net 21 on the outer side of the cylindrical filter paper 22 with folded edges, and insert the inner protective net 23 on the inner side to shape the filter paper 22.

[0052] Step 2: Place the filter element on the shaping device for filter element production, close the outer protective nets 21 at both ends or one end of the filter element, expand the inner protective net 23, and fix the filter paper 22 to the inner and outer protective nets 21.

[0053] Step 3: Inject glue into the injection mold, and place the expanded and closed filter element vertically on the injection mold; after the glue foams and solidifies, remove the injection mold.

[0054] Preferably, the inner and outer protection nets 21 of the filter element are metal nets, preferably zinc alloy metal. When the metal net is bent into a circular structure, the following steps can be taken: Step 1.1, the filter element protection net is first folded into a single side with a width of 6mm using a bite machine, and then bent and flattened; Step 1.2, the two ends of the protection net are overlapped, and the folded single side of the filter element protection net is placed outside; Step 1.3, start the switch spot welding.

[0055] Preferably, the folded edges of the filter paper 22 are flat and vertical without being skewed or curved.

[0056] In step 2, the inner protection net 23 of the filter element is expanded outward at a distance of 15 to 22 mm from the upper end, and the maximum expansion distance b1 is 2 to 6 mm. The outer protection net 21 is closed inward, and the maximum closing distance b2 is 2 to 6 mm. Alternatively, the bending angle a1 of the outer protection net 21 closing inward is 2 to 10°, and similarly, the bending angle a2 of the inner protection net 23 expanding outward is also 2 to 10°.

[0057] In step 3, first inject glue into the injection mold, and after the glue foams for 20 to 30 seconds, insert the filter element vertically into the mold cavity of the injection mold and place it in place; after the filter element and the injection mold are assembled, the limit iron block should be pressed immediately, and a certain pressure should be maintained, and it should be left to stand for about 2 minutes. Then, remove the limit iron block, and put the filter element with the injection mold into the oven and let it stand for 6-8 minutes.

[0058] Preferably, in step 3, when the injection mold is removed, it is placed on a demoulding device for demoulding.

[0059] The shaping device for filter element production is applied to the filter element production process to improve the production efficiency of the filter element.

[0060] Compared with the prior art, the power part 11 of the present invention drives the shaping mold 12 to shape the inner and outer protective nets of the filter element, so that the inner protective net is expanded and the outer protective net is closed, making the injection process more convenient and faster. The present invention has a simple structure, simple operation, and improves production efficiency and production quality.

[0061] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but it does not mean that the implementation of the present invention is limited to this.
