The end cover is uniformly rotated under the drive of the first end cover clamping assembly 6, at the same time, the infrared radiator of the first infrared heating assembly 7 emits infrared rays towards the end cover, so that the upper end surface of the end cover heats and melts. After the lower end of the filter core and the upper end of the end cover heat and melt, the first filter core clamping assembly 4, the hot plate heating assembly 5, the first end cover clamping assembly 6 and the first infrared heating assembly 7 stop acting or reset.

[0064] 5. The horizontal moving seat 21 is shifted to the second position as shown in the figure. Figure 2

[0065] ​​6. The first filter element clamping assembly 4 moves downward under the drive of the vertical moving seat 31, so that the lower end of the filter element is in contact with the end cover on the first end cover clamping assembly 6. After the lower end of the filter element and the upper end of the end cover cool and solidify, the first end cover clamping assembly 6 moves upward and resets under the drive of the vertical moving seat 31. The left clamping plate 41 and the right clamping plate 42 separate and are released, and the filter element can be removed, completing the hot-melt welding of the lower end of the filter element and the end cover.

[0066] Compared with existing conventional hot plate infrared filter welding machines, the above-mentioned filter element welding device has the following advantages:

[0067] 1. Both the end cap clamping assembly and the hot plate heating assembly are mounted on a horizontal moving base, enabling synchronous sliding movement. The infrared heating assembly is fixedly set. Compared with existing technologies, this eliminates a large number of drive and moving structures, further simplifying the structure, reducing the number of parts, and lowering costs.

[0068] 2. Through structures such as limiters and positioning plates, the filter element and end cap are accurately positioned, ensuring that the filter element and end cap can maintain stable and reliable contact pressure during the welding process, thereby ensuring a strong weld and high welding quality.

[0069] 3. With adjustable positioning blocks and screws, replaceable adjustment plates, and stepped positioning grooves, it can accommodate the welding of filter elements of different lengths and diameters, thus having better versatility. Example 2

[0070] like Figures 6-7 As shown, a filter element welding device is mainly different from Embodiment 1 in that it adds a second filter element clamping assembly 8, a second end cap clamping assembly 9, and a second infrared heating assembly 10.

[0071] The structure of the second filter element clamping assembly 8 is the same as that of the first filter element clamping assembly 4, and the second filter element clamping assembly 8 is also mounted on the vertical moving seat 31 and located to the right of the first filter element clamping assembly 4.

[0072] The structure of the second end cap clamping assembly 9 is the same as that of the first end cap clamping assembly 6, and the second end cap clamping assembly 9 is also mounted on the horizontal moving seat 21 and located on the right side of the hot plate heating assembly 5.

[0073] The second infrared heating component 10 is fixedly installed on the back plate 12 and is located on the right side of the second filter element clamping component 8.

[0074] The working steps of the above-mentioned filter element welding device are as follows:

[0075] 1. The first filter element is fixedly clamped by the first filter element clamping assembly 4, and the first end cap is fixedly clamped by the first end cap clamping assembly 6;

At this time, the first filter element clamping assembly 4, the hot plate heating assembly 5, the first end cap clamping assembly 6, and the first infrared heating assembly 7 are activated, and the lower end of the first filter element and the upper end of the first end cap begin to be heated and melted. At the same time, the second filter element is fixedly clamped by the second filter element clamping assembly 8, and the second end cap is fixedly clamped by the second end cap clamping assembly 9.

[0077] 3. Slide the horizontal moving seat 21 to the position as shown. Figure 7 In the second position shown, the first end cap clamping assembly 6 is aligned with the first filter element clamping assembly 4, the second filter element clamping assembly 8 is aligned with the hot plate heating assembly 5, and the second end cap clamping assembly 9 is aligned with the second infrared heating assembly 10. At this time, the first filter element clamping assembly 4 can move downward under the drive of the vertical moving seat 31, so that the lower end of the first filter element contacts and fuses with the first end cap on the first end cap clamping assembly 6. At the same time, the second filter element clamping assembly 8, the hot plate heating assembly 5, the second end cap clamping assembly 9, and the second infrared heating assembly 10 move, and the lower end of the second filter element and the upper end of the second end cap begin to be heated and melted.

[0079] 5. Repeat steps 2-4 continuously.

[0080] The aforementioned filter element welding device can simultaneously heat and melt another set of filter elements and end caps while one set of filter elements is in contact and fused with the end cap, thus achieving continuous welding operations between the two sets of filter elements and end caps, further improving work efficiency.

[0081] Meanwhile, through reasonable layout, only one set of horizontal moving components can drive the first end cap clamping component 6 and the second end cap clamping component 9 to move synchronously at the same time. Only one set of vertical moving components can drive the first filter element clamping component 4 and the second filter element clamping component 8 to move synchronously at the same time. Moreover, only one set of hot plate heating components 5 is needed to alternately heat the filter elements on the first filter element clamping component 4 and the second filter element clamping component 8, thereby further improving the utilization rate of the horizontal moving components, vertical moving components, and hot plate heating components, making the structure not only compact but also further reducing costs.
