Description

Technical Field

[0001] This invention relates to the field of air conditioning filter processing technology, specifically to a fully automatic air conditioning filter folding and cutting device. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demands for indoor and outdoor air quality, the cabin air filter, as a core component of automotive air conditioning systems and indoor air purification equipment, primarily functions to filter impurities such as dust, pollen, particulate matter, and harmful gases from the air, ensuring air quality inside the cabin or driver's compartment. It also prevents impurities from entering the air conditioning system, causing component wear, and extending the lifespan of the air conditioning equipment. The filtration performance of the cabin air filter is closely related to the folding structure of the filter paper. A reasonable folding design can significantly increase the effective filtration area of ​​the filter paper and improve filtration efficiency. The sealing quality and dimensional accuracy of the filter paper directly determine the sealing performance of the filter. If the sealing is not firm or there are deviations in the corner dimensions, gaps will appear after the cabin air filter is installed, allowing unfiltered air to enter directly through the gaps, severely affecting the filtration effect.

[0003] In the existing technology for filter paper folding and cutting processes, most equipment can only perform a single folding or cutting function, failing to achieve fully automated integrated operation. Some equipment claiming to have folding and cutting functions suffers from low folding accuracy and uneven creases. Furthermore, the cutting process is prone to filter paper tearing and uneven cuts, requiring manual secondary trimming of the semi-finished product, increasing process complexity and reducing production efficiency. Existing equipment typically requires transferring the semi-finished product to specialized edge-sealing equipment after the folding and cutting process. This process requires manual handling and positioning, which is time-consuming and labor-intensive, and prone to inaccurate edge-sealing due to positioning deviations, affecting the sealing effect. Existing technology lacks an automatic trimming mechanism for the edges of the sealed filter paper. Due to factors such as material shrinkage and equipment positioning errors during edge-sealing, burrs, protrusions, or dimensional errors are prone to appear at the sealed edges. Without trimming, the air conditioning filter cannot be precisely matched to the installation position during installation, resulting in installation gaps. Summary of the Invention

A fixed shell 23 is fixedly connected to the end of the second slide seat 17 away from the base plate 1. A lifting slide rail 4 is fixedly connected inside the fixed shell 23. A first slide seat 16 is slidably connected inside the lifting slide rail 4. The first slide block 16 is fixedly connected to the fixed frame 19. A mounting shell 26 is fixedly connected to the upper surface of the adjusting plate 6. A compression roller 33 is rotatably connected inside the mounting shell 26. An air cylinder 28 is fixedly connected to the upper surface of the base plate 1. A piston plate 49 is slidably connected inside the air cylinder 28. A piston rod 48 is fixedly connected to one end of the piston plate 49 near the sliding plate 20, and the piston rod 48 is fixedly connected to the sliding plate 20. An air pipe 59 is fixedly connected to the air cylinder 28. The dust collection box 50 and the rigid tube 54 are both connected to the air cylinder 28 through the air pipe 59. A discharge port 52 is opened on the dust collection box 50. A lifting column 10 is fixedly connected to the adjusting plate 6.

A guide clamp 22 is fixedly connected to the end of the fixing frame 19 away from the adjusting slide rail 2.

[0021] To improve production efficiency, this invention incorporates a processing assembly. Two symmetrically arranged first spiral conveyor plates 5 fold the filter paper, and when they reach below the first cutter 21, they cut the filter paper at its center. A second spiral conveyor plate 9 and two symmetrically arranged guide plates 22 continue to support and convey the folded filter paper. When the filter paper reaches the second cutter 24, it is completely cut. Using two sets of cutters avoids uneven cuts caused by uneven force during a single cut, improving cutting accuracy. The cut filter paper is directly conveyed onto the conveyor belt 29 for automatic edge sealing, achieving integrated operation and effectively improving the device's production efficiency. When the cutter moves upward, the scraper 53 scrapes away the adhering material along the cutter surface, and the air pump 28 is in the air intake state, which creates negative pressure in the dust collection box 50 to suck the adhering material into it; when the cutter moves downward, the air pump 28 exhausts and pushes the magnetic block 56 to move along the inner wall of the rigid tube 54. The scraper 57 is provided with a magnetic ring at one end near the outer wall of the rigid tube 54. The magnetic block 56 drives the scraper 57 to push the adhering material on the screen plate 55 out through the discharge port 52, realizing the self-cleaning of the cutter and further improving the cutting accuracy.

[0022] Specifically, firstly, the power system associated with the positive and negative threaded screws 18 drives them to rotate, adjusting the distance between the two first spiral conveyor plates 5. The power system associated with the first slide block 16 adjusts the height of the first spiral conveyor plate 5. Since the guide plate 22 is fixedly connected to the fixed frame 19, the guide plate 22 is adjusted synchronously when the first spiral conveyor plate 5 is adjusted. The power system associated with the first spiral conveyor plate 5 drives the first spiral conveyor plate 5 to rotate, placing the filter paper into the gap of the first spiral conveyor plate 5. As the first spiral conveyor plate 5 rotates, it automatically folds the filter paper. When the filter paper moves to the first cutter 21, the first cutter 21 is pushed by the power system. The filter paper is cut in the middle by the first cutter 21. During the cutting process, when the first cutter 21 moves downward, the piston rod 48 pushes the piston plate 49 to slide along the inner wall of the air cylinder 28, and the air cylinder 28 is in the exhaust state. The one-way valve of the air pipe 59 allows gas to enter only into the rigid pipe 54, which in turn pushes the magnetic block 56 to slide along the inner wall of the rigid pipe 54. A magnetic ring is provided at one end of the scraper 57 near the outer wall of the rigid pipe 54. The magnetic block 56 drives the scraper 57 to push the adhering material on the sieve plate 55 out through the discharge port 52, automatically cleaning the dust collection box 50. When the first cutter 21 moves upward, the air cylinder 28 is in the intake state, and the one-way valve in the air pipe 59 closes the connection with the rigid pipe 54. In the open state, and during the closing of the one-way valve, the gas in the rigid tube 54 is drawn into the air cylinder 28. Under the rebound force of the compression spring 58, the magnetic block 56 and the scraper 57 automatically reset. At this time, the one-way valve is completely closed, and the air tube 59 creates a negative pressure in the dust collection box 50, automatically drawing the adhesive scraped off by the scraper 53 into the dust collection box 50, thus achieving automatic cleaning of the first cutter 21. All of the above components can be installed at the second cutter 24, and the working principle of each component is the same, so it will not be described in detail here. The power system matching the second spiral conveyor plate 9 drives the second spiral conveyor plate 9 to rotate, conveying the filter paper cut in the middle. The first spiral conveyor plate 5 contacts both ends of the filter paper for conveying. A support plate is installed at one end of the fixed frame 19 near the base plate 1 to support and guide the filter paper. The second spiral conveyor plate 9 contacts the upper end of the filter paper for conveying. After the first cutter 21 cuts the filter paper in the middle, the first spiral conveyor plate 5 and the second spiral conveyor plate 9 together convey the filter paper to the end of the second cutter 24 near the side of the first cutter 21, so as to avoid the first spiral conveyor plate 5 affecting the cutting of the second cutter 24. The two symmetrically arranged second cutters 24 completely cut the filter paper. The guide plate 22 has a notch on the extension path of the second cutter 24 to avoid affecting the movement of the second cutter 24. The diameter of the second spiral conveyor plate 9 is smaller than the distance between the two second cutters 24.

[0023] Secondly, the guide plate 22 supports both ends of the cut filter paper. The second spiral conveyor plate 9 contacts the upper end of the filter paper for conveying. Robotic arms are installed on both sides of the second spiral conveyor plate 9, which can automatically insert the positioning plate into the gaps in the filter paper to shape it. The robotic arms are existing devices and will not be described in detail here. The second spiral conveyor plate 9 conveys the shaped filter paper onto the conveyor belt 29. The conveyor belt 29 rotates and drives the filter paper to be conveyed. The glue roller 30 contacts both ends of the filter paper and automatically releases quick-drying glue to both sides of the filter paper. The guide roller... 31 drives the sealing tape to adhere to both ends of the filter paper, and the rotation speed of the guide wheel 31 is synchronized with the rotation speed of the conveyor belt 29. The filter paper becomes a filter plate under the sealing action of the tape at both ends. As the conveyor belt 29 conveys, the two sides of the filter plate are squeezed by the extrusion roller 33, making the tape adhere more tightly to both ends of the filter paper. When the sealing tape connecting the two filter plates moves to below the cutting knife 34, the cutting knife 34 moves down along the lifting column 10 to cut the sealing tape. At the same time, the guide clamp 35 abuts against the positioning plate to realize automatic sealing of the filter paper.

[0024] refer to Figures 1-10 The auxiliary components include adjusting plates 6 and conveyor belts 29. Two adjusting plates 6 are symmetrically installed on the upper surface of the base plate 1, and the adjusting plates 6 are slidably connected to the base plate 1. Roller wheels 30 and guide wheels 31 are rotatably connected to the adjusting plates 6. The conveyor belt 29 is rotatably connected to the end of the adjusting plates 6 near the sleeve 32. Two guide rails 13 are fixedly connected to the upper surface of the base plate 1, and two carriages 14 are slidably connected between the two guide rails 13. Two cutting seats 45 are symmetrically installed in the carriages 14, and the cutting seats 45 are slidably connected to the carriages 14. Multiple columns 11 are fixedly connected to the upper surface of the base plate 1. A movable slide rail 12 is fixedly connected to the end of every two columns 11 away from the base plate 1. A slider 37 is slidably connected in the movable slide rail 12, and a threaded rod 47 is rotatably connected in the movable slide rail 12. The threaded rod 47 is threadedly connected to the slider 37. The ends of the two sliders 37 away from the base plate 1 are fixedly connected to a fixed plate 15. The fixed plate 15 is equipped with a hydraulic cylinder 36. The output end of the hydraulic cylinder 36 is fixedly connected to a connecting plate 40. Two track plates 41 are symmetrically installed on the end of the connecting plate 40 near the base plate 1. Two shift plates 42 are slidably connected between the two track plates 41. A clamping slide rail 43 is fixedly connected on the end of the shift plate 42 near the base plate 1. Two clamping plates 44 are symmetrically installed in the clamping slide rail 43, and the clamping plates 44 are slidably connected to the clamping slide rail 43. A protective corner plate 39 and a limiting block 38 are fixedly connected on the end of the cutting seat 45 away from the base plate 1. A cutter holder 46 is installed in the protective corner plate 39, and the cutter holder 46 is slidably connected to the limiting block 38.

[0025] To improve the fit between the air conditioning filter and the installation station, this invention includes an auxiliary component. After the air conditioning filter is sealed, it is transferred to the trimming area by multiple clamping plates 44. The slots of the four limiting blocks 38 clamp the four corners of the air conditioning filter. During the movement of the cutter frame 46, the edges and corners of the air conditioning filter are automatically trimmed, thus achieving automatic trimming of the four edges and corners of the air conditioning filter.

[0026] Specifically, the hydraulic cylinder 36 pushes the connecting plate 40 downward, distributing the clamping plates 44 around the filter plate. A rotating ring is installed between the hydraulic cylinder 36 and the fixed plate 15. The angle of the clamping plates 44 can be adjusted by rotating the rotating ring, and the rotating ring does not affect the extension and retraction of the hydraulic cylinder 36. The power system of the threaded rod 47 drives its rotation, which moves the fixed plate 15 and the clamping plates 44. When the clamping plates 44 move above the filter plate, the power system of the double-ended screw drives its rotation. The double-ended screw has a structure with left-hand and right-hand threads symmetrically machined on the same screw, causing the clamping slide rail 43 to move along the slide groove of the track plate 41. The rotation of the double-ended screw in the clamping slide rail 43... The clamping plate 44 is driven to move. By adjusting the clamping plate 44 in two directions along the track plate 41 and the clamping slide rail 43, the filter plate is clamped. The position of the cutting seat 45 is adjusted along the slide 14 by the power system of the cutting seat 45. The slide 14 is adjusted along the guide rail 13. The position of the cutting seat 45 is adjusted by the above two directions. The clamping plate 44 moves the filter plate above the cutting area and locks the four corners of the filter plate into the slots of the limiting block 38. By moving the cutter holder 46, the cutter on the cutter holder 46 cuts the four corners of the filter plate. By adjusting the angle of the hydraulic cylinder 36, the position of the cutting angle of the filter plate can be changed to achieve the cutting of the four corners of the filter plate.

[0027] The working principle of this invention is as follows: Filter paper is placed into the gap of the first spiral conveyor plate 5. As the first spiral conveyor plate 5 rotates, the filter paper is automatically folded. When the filter paper moves to the first cutter 21, the first cutter 21, driven by the power system, cuts the filter paper in the middle. The power system of the second spiral conveyor plate 9 drives the second spiral conveyor plate 9 to rotate, conveying the cut filter paper. The second spiral conveyor plate 9 contacts the upper end of the filter paper for conveying. The first cutter 21 cuts the filter paper in the middle. When the first cutter 21 moves downward, the piston rod 48 pushes the piston plate 49 to slide along the inner wall of the air cylinder 28. The air cylinder 28 is in the exhaust state. The one-way valve of the air pipe 59 ensures that gas can only enter the rigid pipe 54, thereby pushing the magnetic block 56. Sliding along the inner wall of the rigid tube 54, the magnetic block 56 drives the scraper 57 to push the adhering material on the sieve plate 55 out through the discharge port 52, automatically cleaning the dust collection box 50. When the first cutter 21 moves upward, the air cylinder 28 is in the air intake state, and the one-way valve in the air pipe 59 is closed and connected to the rigid tube 54. During the closing of the one-way valve, the gas in the rigid tube 54 is drawn into the air cylinder 28. Under the rebound force of the compression spring 58, the magnetic block 56 and the scraper 57 automatically reset. At this time, the one-way valve is completely closed, and the air pipe 59 creates a negative pressure in the dust collection box 50, automatically drawing the adhering material scraped off by the scraper 53 into the dust collection box 50, realizing the automatic cleaning of the first cutter 21. The first spiral conveyor plate 5 and the second spiral conveyor plate 9 together convey the filter paper to the... The second cutter 24, located near the first cutter 21, is positioned to prevent the first spiral conveyor plate 5 from interfering with the cutting action of the second cutter 24. Two symmetrically arranged second cutters 24 completely cut the filter paper. A guide plate 22 supports both ends of the cut filter paper. The second spiral conveyor plate 9 contacts the upper end of the filter paper for transport. Robotic arms on both sides of the second spiral conveyor plate 9 automatically insert positioning plates into the gaps in the filter paper to shape it. The second spiral conveyor plate 9 then transports the shaped filter paper onto the conveyor belt 29. The conveyor belt 29 rotates and drives the filter paper forward. Roller rollers 30 contact both ends of the filter paper and automatically release quick-drying adhesive onto both sides. Guide rollers 31 drive the sealing tape along the edges to adhere to both ends of the filter paper. As the conveyor belt 29 moves forward... The conveyor belt 9 presses the filter plates together with the extrusion rollers 33, making the tape and filter paper adhere more tightly. When the sealing tape connecting the two filter plates moves to below the cutting blade 34, the cutting blade 34 moves downward along the lifting column 10 to cut the sealing tape. At the same time, the guide clamp 35 abuts against the positioning plate. After the sealing is completed, the air conditioning filter is transferred to the trimming area through multiple clamping plates 44. The slots of the four limit blocks 38 clamp the four corners of the air conditioning filter. During the movement of the cutter frame 46, the edges and corners of the air conditioning filter are automatically trimmed. A rotating ring is installed between the hydraulic cylinder 36 and the fixed plate 15. The angle of the clamping plate 44 can be adjusted by rotating the rotating ring. The cutting angle of the filter plate can be changed by adjusting the angle of the hydraulic cylinder 36.
