Description

Technical Field

[0001] This invention relates to the field of filter element ring forming machine technology, and more particularly to a filter element ring forming machine. Background Technology

[0002] Filter cartridges are made by folding a flat filter cartridge into a wavy shape, and then fixing the two ends of the wavy filter cartridge together to form a ring-shaped filter cartridge. When fixing the two ends of the wavy filter cartridge together, a filter cartridge ring forming machine is needed. Cut aluminum clips are clamped at both ends of the filter cartridge, and the filter cartridge ring forming machine rolls the aluminum clips to clamp the two ends of the filter cartridge together.

[0003] When inserting the two ends of the corrugated filter element into the aluminum retaining strips, the two ends of the corrugated filter element are manually aligned before being inserted into the aluminum retaining strips. Then, the aluminum retaining strips are deformed by rolling between the driving and driven wheels to fix the two ends of the filter element. Because the alignment of the two ends of the corrugated filter element is done manually without auxiliary tools, it is common for the two ends of the corrugated filter element to be inserted into the aluminum retaining strips without being aligned, or for the two ends of the corrugated filter element to be partially inside the aluminum retaining strips. This results in the filter element forming an irregular circle, and also causes the two ends of the filter element to be incompletely connected, that is, partially connected and partially disconnected, with an unstable connection. As a result, the connection between the two ends of the filter element is prone to cracking during use.

[0004] In view of this, the inventors of this application have invented a filter element ring forming machine. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a filter element ring forming machine.

[0006] The present invention solves the above-mentioned technical problems through the following technical means: it includes a ring-forming machine body and a placement platform. The ring-forming machine body is fixed on the top surface of the placement platform. A driving wheel is rotatably connected to the bottom of the ring-forming machine body. A driven wheel and several placement wheels are rotatably connected inside the placement platform. The driven wheel is located directly below the driving wheel. The several placement wheels are all located on one side of the driven wheel. Placement grooves are opened on the surface of the placement wheels. A retaining strip is placed in the placement groove. An installation block is slidably connected to the surface of the placement platform. Two opposing outer limiting strips are fixed on one side of the installation block. Each of the two opposing outer limiting strips has a limiting groove on its opposing surface. The limiting groove can restrict the bend of the filter element inside.

[0007] Furthermore, the limiting groove is V-shaped, and the openings of adjacent V-shaped limiting grooves are arranged opposite to each other.

[0008] Furthermore, a slide rail is fixed on the top surface of the placement platform near the side of the placement platform, and a groove adapted to the slide rail is opened on the bottom surface of the mounting block. The slide rail restricts the mounting block to slide on its surface through the groove.

[0009] Furthermore, the groove is a dovetail groove, and the slide is a dovetail strip adapted to the dovetail groove.

[0010] Furthermore, an adjustment groove is provided on the side of the mounting block connected to the outer limiting strip. A first limiting block is fixed on the side of the outer limiting strip near the mounting block. The adjustment groove restricts the first limiting block from sliding up and down inside. The adjustment groove is also rotatably connected to a first adjustment component. The first adjustment component passes through the first limiting block. Rotating the first adjustment component causes the opposing first limiting blocks to move closer or further away from each other simultaneously.

[0011] Furthermore, the first adjustment component includes a first bidirectional threaded rod and a first rotary knob. The first bidirectional threaded rod is rotatably connected in the adjustment groove. The first bidirectional threaded rod passes through the first limiting block and the mounting block. The first bidirectional threaded rod and the first limiting block are screwed together by threads. The top end of the first bidirectional threaded rod extends upward and passes through the mounting block. The top end of the first bidirectional threaded rod protrudes from the top surface of the mounting block. The first rotary knob is fixed on the top surface of the first bidirectional threaded rod.

[0012] Furthermore, an inner limiting strip is provided between the oppositely arranged outer limiting strips, and the inner limiting strip has a pointed end near the limiting groove.

[0013] Furthermore, a second limiting block is fixed to the side of the inner limiting strip near the mounting block, and the adjusting groove restricts the second limiting block from sliding up and down inside. A second adjusting component is also rotatably connected inside the adjusting groove. The second adjusting component passes through the second limiting block, and rotating the second adjusting component causes the relatively arranged second limiting blocks to move closer or further away from each other at the same time.

[0014] Furthermore, the second adjustment component includes a second bidirectional threaded rod and a second rotary knob. The second bidirectional threaded rod is rotatably connected in the adjustment groove. The second bidirectional threaded rod passes through the second limiting block and the mounting block. The second bidirectional threaded rod and the second limiting block are screwed together. The top end of the second bidirectional threaded rod extends upward and passes through the mounting block. The top end of the second bidirectional threaded rod protrudes from the top surface of the mounting block. The second rotary knob is fixed to the top surface of the second bidirectional threaded rod.

[0015] The beneficial effects of this invention are:

[0016] (1) The filter element ring forming machine of the present invention places the last outward protrusion of the last bend at both ends of the filter element into the upper limiting groove, and similarly places the lower outward protrusion into the lower limiting groove. At this time, the two ends of the filter element are aligned. Push the two ends of the filter element into the retaining strip. After the operation is completed, push the mounting block and the retaining strip so that the retaining strip and the two ends of the filter element pass between the drive wheel and the placement table. Roll the retaining strip to deform it and complete the fixation of the two ends of the filter element. With the assistance of the mounting block and the outer limiting strip, it is convenient to align the two ends of the wavy filter element before inserting it into the retaining strip. When rolling the retaining strip, the two ends of the wavy filter element can be completely located in the retaining strip, which improves the connection firmness of the two ends of the filter element, that is, improves the product quality of the filter element.

[0017] (2) The filter element ring forming machine of the present invention rotates the first bidirectional threaded rod, and the first bidirectional threaded rod drives the relatively set first limiting blocks to move closer or further away from each other through the thread, and adjusts the spacing between the outer limiting strips until the spacing between the outer limiting strips can lock the last bend and outward protrusion at both ends of the filter element, so that the filter element ring forming machine can fix the two ends of filter elements of different specifications.

[0018] (3) The filter element ring forming machine of the present invention has an inner limit strip set between the outer limit strips. The inner limit strip has a pointed end near the limit groove, which better fits the inner side of the filter element bend and forms a support inside the filter element. Combined with the limit of the outer limit strip, it can effectively prevent the filter element from shifting when it moves with the mounting block, and further improve the fixing quality of the two ends of the filter element.

[0019] (4) By adjusting the spacing between the relatively set outer limit strips and the spacing between the relatively set inner limit strips, the filter element ring forming machine can effectively support filter elements of different specifications. When fixing the two ends of the filter element, the filter element will not shift, thus improving the fixing quality of the two ends of the filter element. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0037] Example 1

[0038] Please see Figure 1 As shown, the filter element ring forming machine described in this embodiment includes a ring forming machine body 10, a driving wheel 11, a placement platform 12, a driven wheel 13, and placement wheels 16. The ring forming machine body 10 is a roller ultrasonic ring forming machine body, which is fixed to the top surface of the placement platform 12. The driving wheel 11 is rotatably connected to the bottom of the ring forming machine body 10. The driven wheel 13 and several placement wheels 16 are rotatably connected inside the placement platform 12. The driven wheel 13 is located directly below the driving wheel 11, and the several placement wheels 16 are all located on one side of the driven wheel 13. Figure 1 , Figure 3 As shown, the surface of the placement wheel 16 is provided with a placement groove 161, such as... Figure 2 As shown, a retaining strip 17 is placed in the placement groove 161, which restricts the retaining strip 17 inside. After aligning the two ends of the corrugated filter element, it is inserted into the retaining strip 17. Then, the retaining strip 17 and the two ends of the corrugated filter element are passed through the gap between the driving wheel 11 and the driven wheel 13 to roll the retaining strip 17, causing the retaining strip 17 to deform and achieve the purpose of fixing the two ends of the filter element.

[0039] A mounting block 2 is slidably connected to the surface of the placement platform 12. Two opposing outer limiting strips 3 are fixed to one side of the mounting block 2. Each of the opposing surfaces of the two outer limiting strips 3 has a limiting groove, which can confine the bend of the filter element within its groove. Figure 2 As shown, in this embodiment, the limiting groove is "V" shaped, and the openings of adjacent "V" shaped limiting grooves are arranged opposite each other.

[0040] To facilitate the movement of the mounting block 2 on the surface of the placement platform 12, a slide rail 14 is fixed on the top surface of the placement platform 12 near the side of the placement platform 12. The bottom surface of the mounting block 2 is provided with a groove 15 that matches the slide rail 14. The slide rail 14 restricts the mounting block 2 to slide on its surface through the groove 15. In this embodiment, the groove 15 is a dovetail groove, and the slide rail 14 is a dovetail strip that matches the dovetail groove.

[0041] In use, place the upper bend protruding outward at both ends of the filter element into the upper limiting groove, and similarly place the lower bend protruding outward into the lower limiting groove. At this point, the two ends of the filter element are aligned. Push both ends of the filter element into the retaining strip 17. After operation, as shown... Figure 4 As shown, pushing the mounting block 2 and the retaining strip 17 causes the retaining strip 17 and both ends of the filter element to pass between the drive wheel 11 and the placement table 12, rolling the retaining strip 17 to deform it and fix both ends of the filter element. With the assistance of the mounting block 2 and the outer limiting strip 3, it is convenient to align the two ends of the wavy filter element before inserting it into the retaining strip. When rolling the retaining strip 17, both ends of the wavy filter element can be completely located within the retaining strip, improving the connection firmness of the two ends of the filter element, thus improving the product quality of the filter element.

[0042] Example 2

[0043] In actual use, the folding width of filter elements of different specifications will also be different. In order to facilitate the adjustment of the spacing between the relatively set outer limiting strips 3 and to match filter elements of different specifications, this embodiment is further improved on the basis of embodiment one.

[0044] Please see Figure 8 , Figure 9 As shown, unlike Embodiment 1, the mounting block 2 is provided with an adjustment groove 21 on the side where it connects to the outer limiting strip 3. The outer limiting strip 3 is fixed with a first limiting block 31 on the side near the mounting block 2. The adjustment groove 21 restricts the first limiting block 31 from sliding up and down inside. The adjustment groove 21 is also rotatably connected to a first adjustment component 4. The first adjustment component 4 passes through the first limiting block 31 and the mounting block 2. Rotating the first adjustment component 4 causes the oppositely arranged first limiting blocks 31 to move simultaneously, moving closer or further away from each other. The first limiting block 31 drives the outer limiting strip 3 to move accordingly.

[0045] Please see Figure 8 As shown, the first adjustment component 4 includes a first bidirectional threaded rod 41 and a first rotary knob 42. The first bidirectional threaded rod 41 is rotatably connected in the adjustment groove 21. The first bidirectional threaded rod 41 passes through the first limiting block 31 and the mounting block 2. The first bidirectional threaded rod 41 and the first limiting block 31 are screwed together. The top end of the first bidirectional threaded rod 41 extends upward and passes through the mounting block 2. The top end of the first bidirectional threaded rod 41 protrudes from the top surface of the mounting block 2. The first rotary knob 42 is fixed on the top surface of the first bidirectional threaded rod 41.

[0046] In use, rotating the first bidirectional threaded rod 41 causes the opposing first limiting blocks 31 to move closer or further apart via the thread. Adjusting the spacing between the outer limiting strips 3 continues until the spacing between the outer limiting strips 3 can lock the last outwardly protruding bend at both ends of the filter element. Figure 8 As shown, the convenient filter ring forming machine can fix the two ends of filter elements of different specifications.

[0047] Example 3

[0048] When the outer limiting strip 3 limits the last bend and outward protrusion at both ends of the filter element, the filter element may shift at both ends due to the lack of internal support when the mounting block 2 moves the filter element. This may cause the filter element to align at both ends and then move again, resulting in misalignment or other issues. Consequently, the filter element may not be completely fixed at both ends or may have an irregular shape.

[0049] Please see Figure 12 As shown, in order to solve the above-mentioned problems, the design is further improved based on the second embodiment. The difference is that there are oppositely arranged inner limiting strips 6 between the oppositely arranged outer limiting strips 3. The inner limiting strip 6 has a pointed end near the limiting groove, which better fits the inner side of the filter element bending point and forms support inside the filter element. Combined with the limiting of the outer limiting strips 3, it can effectively prevent the filter element from shifting when it moves with the mounting block 2, and further improve the fixing quality of the two ends of the filter element.

[0050] Please see Figure 12 , Figure 13 As shown, a second limiting block 61 is fixed on the side of the inner limiting strip 6 near the mounting block 2. The adjusting groove 21 restricts the second limiting block 61 to slide up and down inside. A second adjusting component 5 is also rotatably connected inside the adjusting groove 21. The second adjusting component 5 passes through the second limiting block 61 and the mounting block 2. Rotating the second adjusting component 5 causes the relatively set second limiting blocks 61 to move simultaneously, moving closer or further away from each other.

[0051] The second adjustment component 5 includes a second bidirectional threaded rod 51 and a second rotary knob 52. The second bidirectional threaded rod 51 is rotatably connected in the adjustment groove 21. The second bidirectional threaded rod 51 passes through the second limiting block 61 and the mounting block 2. The second bidirectional threaded rod 51 and the second limiting block 61 are screwed together. The top end of the second bidirectional threaded rod 51 extends upward and passes through the mounting block 2. The top end of the second bidirectional threaded rod 51 protrudes from the top surface of the mounting block 2. The second rotary knob 52 is fixed on the top surface of the second bidirectional threaded rod 51.

[0052] By adjusting the spacing between the relatively set outer limiting strips 3 and the relatively set inner limiting strips 6, the filter element ring forming machine can effectively support filter elements of different specifications. When fixing the two ends of the filter element, the filter element will not shift, thus improving the fixing quality of the two ends of the filter element.
