Therefore, this invention proposes a filter element production sealing device.

The transmission belt is driven between the two rotating rollers. Multiple connecting plates are fixedly connected to the outer surface of the transmission belt, and a holding assembly is fixedly connected to one side of the connecting plates. The holding assembly includes a carrying cylinder, with a support plate fixedly connected between the inner circumference of the carrying cylinder. A bottom plate is fixedly connected to the bottom of the carrying cylinder, and the bottom plate is fixed to the connecting plates by bolts. Two support blocks are fixedly connected to the bottom of the bottom plate, and the support blocks are in contact with the outer surface of the transmission belt.

[0007] Furthermore, the hot-press sealing assembly includes a top frame, which is fixed to the top inner wall of the support frame by bolts. A bidirectional threaded rod is rotatably inserted between the two sides of the top frame. A rear clamping plate is threaded onto one end of the bidirectional threaded rod, and a front clamping plate is threaded onto the other end of the bidirectional threaded rod. An upper motor is fixedly connected to one side outer wall of the top frame, and the output end of the upper motor is fixedly connected to one end of the bidirectional threaded rod.
[0008] Furthermore, two guide rods are fixedly connected between the inner walls of the two sides of the top frame, and the rear clamping plate and the front clamping plate are slidably sleeved with the guide rods.
[0009] Furthermore, a side opening is provided on one side of the front clamping plate, a side frame is fixedly connected to one side of the front clamping plate, an electric push rod is fixedly connected to the outer wall of one side of the side frame, and a hot press plate is fixedly connected to one end of the electric push rod, with the hot press plate passing through the side opening.

[0016] 2. Driven by the upper motor, the bidirectional threaded rod rotates, causing the rear clamping plate and the front clamping plate to converge towards the middle, thereby clamping the opening of the packaging bag. Then, driven by the electric push rod, the hot press plate moves and presses on the opening of the packaging bag, thus sealing the opening of the packaging bag, saving time and effort.
[0017] 3. The gas inside the connecting shell is heated by a heating plate, which causes the packaging bag to shrink and wrap around the outside of the filter element, thus fully sealing the filter element and improving the sealing quality. Attached Figure Description

[0026] A holding assembly 4 is fixed to one side of the connecting plate 303 by bolts. The holding assembly 4 includes a carrying cylinder 401. A support plate 402 is welded between the inner circumference of the carrying cylinder 401. The packaging bag is placed vertically on the support plate 402 inside the carrying cylinder 401 with the opening of the packaging bag facing upwards. A bottom plate 403 is welded to the bottom end of the carrying cylinder 401. The bottom plate 403 is fixed to the connecting plate 303 by bolts. Two support blocks 404 are welded to the bottom of the bottom plate 403 to stably support the filter element. The support blocks 404 are in contact with the outer surface of the conveyor belt 302. The circumference of the carrying cylinder 401 is provided with multiple through holes 405. A support frame 2 is welded to the top between the two vertical plates 1. A heat-sealing assembly 5 is provided on the inner wall of the top of the support frame 2.
[0027] The hot-press sealing assembly 5 includes a top frame 501, which is fixed to the top inner wall of the support frame 2 by bolts. A bidirectional threaded rod 503 is rotatably inserted between the two sides of the top frame 501. A rear clamping plate 504 is threaded onto one end of the bidirectional threaded rod 503, and a front clamping plate 505 is threaded onto the other end of the bidirectional threaded rod 503. An upper motor 10 is fixed to one side outer wall of the top frame 501 by bolts. The output end of the upper motor 10 is fixedly connected to one end of the bidirectional threaded rod 503. Two guide rods 502 are welded between the two sides inner walls of the top frame 501. The rear clamping plate 504 and the front clamping plate 505 are slidably sleeved with the guide rods 502. Under the drive of the upper motor 10, the bidirectional threaded rod 503 rotates, thereby causing the rear clamping plate 504 and the front clamping plate 505 to converge towards the middle, thereby clamping the opening of the packaging bag.
[0028] A side opening 506 is provided on one side of the front clamping plate 505. A side frame 507 is fixed to one side of the front clamping plate 505 by bolts. An electric push rod 508 is fixed to the outer wall of one side of the side frame 507 by bolts. A hot press plate 509 is fixed to one end of the electric push rod 508 by bolts. The hot press plate 509 passes through the side opening 506. Driven by the electric push rod 508, the hot press plate 509 moves and presses against the opening of the packaging bag, thereby sealing the opening of the packaging bag. A connecting shell 6 is fixed to the top inner wall of the support frame 2 by bolts. The top inner wall of the connecting shell 6 is connected by... A support shell 7 is bolted to the bottom of both ends of the support shell 7, and a curtain 9 is bolted to the bottom of both ends of the support shell 7. A heating plate 8 is bolted to the inner wall of the top of the support shell 7. The heating plate 8 is used to heat the gas inside the connecting shell 6, so that the packaging bag is heated and shrinks, thereby wrapping the packaging bag around the outside of the filter element and sealing the filter element. Multiple support rollers 13 are rotatably connected between the two vertical plates 1. The support rollers 13 are located in the middle of the conveyor belt 302, thereby supporting the conveyor belt 302. A base 12 is welded to the bottom between the two vertical plates 1.
[0029] The working principle of this embodiment is as follows: First, manually load the filter element into the packaging bag. Then, place the packaging bag vertically inside the carrier cylinder 401 with the opening facing upwards. Next, start the lower motor 11. Driven by the lower motor 11, the rotating roller 301 rotates, thereby driving the conveyor belt 302 to rotate, which in turn moves the filter element. The filter element is then moved to the bottom of the heat-sealing assembly 5, and the conveyor belt 302 stops working. Then, start the upper motor 10. Driven by the upper motor 10, the bidirectional threaded rod 503 rotates, causing the rear clamping plate 504 and the front clamping plate 505 to converge towards the center, thus sealing the packaging bag. The bag opening is clamped. Then, the electric push rod 508 is activated. Driven by the electric push rod 508, the hot press plate 509 moves and presses against the opening of the packaging bag, thereby sealing the opening of the packaging bag. Then, the conveyor belt 302 continues to drive the carrier cylinder 401 to move, thus passing through the curtain 9 at one end of the connecting shell 6 and entering the connecting shell 6. The gas inside the connecting shell 6 is heated by the heating plate 8, which causes the packaging bag to shrink due to heat, thereby wrapping the outside of the packaging bag around the filter element and sealing the filter element. Finally, the sealed filter element passes out through the curtain 9 at the other end of the connecting shell 6, thus completing the sealing of the filter element, which is then collected and taken away by the staff.
