[0002] The main characteristics of pleated filter cartridges include high rejection rate, high flow rate, low pressure drop and wide chemical compatibility. During the production process, these pleated filter cartridges often require sealing caps at both ends and gluing.

[0003] Currently, during the installation of the glue cap, due to the curing period of the glue solution, the glue cap may fall off before the glue solution has fully cured, which will affect the quality of the glue application for sealing the filter element. Summary of the Invention

[0010] Preferably, a rectangular frame is fixedly connected to the bottom of the feeding rack, a movable plate is slidably provided inside the rectangular frame, a pull rod is fixedly connected to the top of the movable plate, an opening is formed at the top inner wall of the rectangular frame, a tension spring is provided at the top of the rectangular frame, the tension spring is sleeved on the outside of the pull rod, a connecting plate is fixedly connected to the rod wall of the pull rod, and the top of the tension spring is fixedly connected to the bottom of the connecting plate.

[0011] Preferably, a fixed cylinder is fixedly connected to the top end of the pull rod, a compression spring is provided inside the fixed cylinder, a push rod is fixedly connected to the end of the compression spring, and the end of the push rod away from the compression spring extends to the outside of the fixed cylinder and is fixedly connected to a lever.

[0012] Preferably, the push rod is configured as a T-shaped rod, and a fixing ring is fixedly connected to the opening of the fixing cylinder, with the push rod located at one end of the fixing cylinder in contact with the fixing ring.

[0013] Preferably, the end of the lever opposite to the push rod has a rounded corner, and an anti-slip pad is provided on the side wall of the lever located at the rounded corner. A lifting plate is fixedly connected to the side wall of the glue gun holder, and the lifting plate is located above the lever.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a sealing and gluing system for folded filter cartridges, which has the following beneficial effects:

[0016] 1. The sealing and gluing system of this pleated filter element can transport the pleated filter element into the machine body through the material conveyor. The piston rod of the cylinder descends, causing the glue gun holder to extend to the side wall of the pleated filter element for glue application. The output shaft of the motor rotates, which drives the bidirectional lead screw to rotate, causing the slider to move along the rod wall of the bidirectional lead screw. This can drive the installation sleeve to be fitted on both sides of the pleated filter element, pressing the glue cap onto both sides of the pleated filter element, thus ensuring stable installation of the glue cap.

[0017] 2. The edge sealing and gluing system of this folded filter element uses the piston rod of the cylinder to retract, which raises the glue gun holder. The lifting plate can be used to move the lever, and the anti-slip pad can prevent slippage. The lever moves the fixed cylinder, the pull rod and the movable plate to rise. At the same time, the tension spring is stretched, which makes the folded filter element roll out from the inside of the material feeder, which is convenient for subsequent edge sealing and gluing processing.

[0018] 3. The sealing and gluing system of this folded filter element, after the cylinder continuously contracts, increases the pressure of the lifting plate on the lever, causing the lifting plate to press along the rounded corner of the lever, which pushes the lever to move and compress the compression spring. This can separate the lifting plate from the lever, and allow the movable plate and the lever to reset under the action of the tension spring. Attached Figure Description

A threaded feed pipe 5 is fixedly connected to the side wall of the glue gun holder 3. One end of the threaded feed pipe 5, facing away from the glue gun holder 3, is fixedly connected to the glue storage tank 4. A feed rack 6 is mounted on the storage tank of the machine body 1. The feed rack 6 is filled with pleated filter cartridges 8. A bidirectional lead screw 9 is rotatably connected to the inner wall of the machine body 1. A motor 10 is fixedly connected to the side wall of the machine body 1. The motor 10... The output shaft extends into the interior of the machine body 1 and is fixedly connected to the end of the bidirectional lead screw 9. A slider 11 is threaded onto the wall of the bidirectional lead screw 9. An installation sleeve 12 is fixedly connected to the side wall of the slider 11. Multiple rubber caps 13 are filled inside the installation sleeve 12. The material conveyor 6 is L-shaped. A connecting seat 7 is fixedly connected to the top side wall of the machine body 1. The material conveyor 6 is fixedly installed inside the connecting seat 7. A strip groove is opened on the surface of the installation sleeve 12 on the machine body 1. The installation sleeve 12 is slidably installed on the inner wall of the strip groove. A baffle 14 is provided on the surface of the strip groove on the machine body 1.

[0026] A rectangular frame 15 is fixedly connected to the bottom of the material conveyor 6. A movable plate 16 is slidably installed inside the rectangular frame 15. A pull rod 18 is fixedly connected to the top of the movable plate 16. An opening is formed at the top inner wall of the rectangular frame 15. A tension spring 17 is installed at the top of the rectangular frame 15 and is sleeved on the outside of the pull rod 18. A connecting plate 19 is fixedly connected to the wall of the pull rod 18. The top of the tension spring 17 is fixedly connected to the bottom of the connecting plate 19. A fixed cylinder 20 is fixedly connected to the top of the pull rod 18. A compression spring 21 is installed inside the fixed cylinder 20. A push rod 22 is fixedly connected to the end of the compression spring 21. The end of the push rod 22 away from the compression spring 21 extends to the outside of the fixed cylinder 20 and is fixedly connected to a lever 23. The push rod 22 is a T-shaped rod. A fixing ring 25 is fixedly connected to the opening of the fixed cylinder 20. The end of the push rod 22 located in the fixed cylinder 20 is in contact with the fixing ring 25. The end of the lever 23 away from the push rod 22 has a rounded corner. An anti-slip pad 24 is provided on the side wall of the lever 23 located at the rounded corner. A lifting piece 26 is fixedly connected to the side wall of the glue gun holder 3. The lifting piece 26 is located above the lever 23.

[0027] In summary, the sealing and gluing system for this pleated filter element allows the pleated filter element 8 to be transported into the machine body 1 via the conveyor frame 6. The piston rod of the cylinder 2 descends, causing the gluing gun 3 to extend to the side wall of the pleated filter element 8 for gluing. The threaded conveyor pipe 5 does not affect the transport of the glue material or the movement of the gluing gun 3. After gluing, the output shaft of the motor 10 rotates, driving the bidirectional lead screw 9 to rotate. This causes the slider 11 to move along the wall of the bidirectional lead screw 9, thereby causing the mounting sleeves 12 to be fitted onto both sides of the pleated filter element 8. This presses the glue caps 13 onto both sides of the pleated filter element 8, ensuring stable installation. The rotation of the output shaft of the motor 10 moves the mounting sleeves 12 away from each other, allowing the pleated filter element to be removed. The baffle 14 further obstructs the rolling out pleated filter element 8, ensuring it falls stably into the slot. The inner wall of the cylinder 2 is closed. When the piston rod of the cylinder 2 retracts, the glue gun holder 3 can be raised. The lifting plate 26 can move the lever 23. The anti-slip pad 24 can prevent slippage. The lever 23 drives the fixed cylinder 20, the pull rod 18 and the movable plate 16 to rise. At the same time, the tension spring 17 is stretched, which can make the folded filter element 8 roll out from the inside of the feed rack 6, which is convenient for subsequent edge sealing and glue application. After the cylinder of the cylinder 2 continues to retract, the pressure of the lifting plate 26 on the lever 23 increases. The lifting plate 26 presses along the rounded corner of the lever 23, which pushes the push rod 22 to move and drive the compression spring 21 to compress. This can separate the lifting plate 26 from the lever 23. The movable plate 16 and the pull rod 18 are reset under the action of the tension spring 17. When the piston rod of the cylinder 2 descends, the pressure of the lifting plate 26 on the lever 23 is greater, which will also cause the lever 23 to retract, so as not to affect the descent of the glue gun holder 3 and the lifting plate 26.
