Description

Technical Field

[0001] This invention relates to machinery and equipment for manufacturing filters, and more specifically to a mechanism for flipping plastic rings and filter paper in the production of filter elements. Background Technology

[0002] Currently, automotive filters generally include components such as a housing, filter element assembly, screw plate, check valve, and bypass valve. The filter element assembly consists of end caps (divided into upper and lower end caps), filter paper, and a central tube. The filter paper is a cylindrical product with a hollow center (for placing the central tube). The end caps are annular and made of metal (or plastic), hence the name metal end caps (or plastic end caps). The end caps consist of two pieces, upper and lower, which are respectively attached to the top and bottom of the filter paper. The assembly process generally involves gluing or heating (using lamps or heating wires). The current requirement is to replace the original metal end caps (or plastic end caps) with plastic rubber rings. The radius of the plastic rubber rings is slightly smaller than that of the original metal end caps (or plastic end caps). A heat welding (or adhesive bonding) method is required to combine the plastic rubber rings and filter paper. The process involves feeding the filter paper, feeding the plastic rubber rings, heating (or adhesive bonding) the plastic rubber rings, welding the two ends of the rubber rings and filter paper (two welding operations), and discharging the finished product. This is a fully manual or semi-automated operation, without any intermediate turning mechanism. Manual operation is still required in the middle, resulting in low automation, poor work efficiency, and difficulty in guaranteeing processing quality. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide an automatic intermediate flipping mechanism for plastic rings and filter paper that can automatically complete the intermediate flipping process of plastic rings and filter paper, achieving orientation reversal and eliminating the need for intermediate operation.

[0004] The objective of this invention is achieved through the following technical solution: an automatic flipping mechanism between a plastic ring and filter paper, comprising a flipping frame, a primary flipping pressing power source mounted on the upper part of the flipping frame, the primary flipping pressing power source being connected to a secondary flipping pressing power source via a lower pressing plate, a flipping pressing head connected below the secondary flipping pressing power source, a flipping power source mounted in the middle of the flipping frame and connected to a flipping mold, and a flipping upper pressing power source mounted at the lower part of the flipping frame and connected to an upper pressing head.

[0005] A tilting limit cylinder is installed on the tilting frame and on the side of the tilting mold. The tilting limit cylinder is connected to a tilting limit block, which is adjacent to the tilting mold. The tilting power source is connected to a handwheel via a second screw, which is mounted on the top of the tilting frame.

[0006] The flipping mold is equipped with positioning holes, which correspond to the position of the upper pressing head before flipping and to the position of the lower pressing head after flipping. The primary pressing power source, secondary pressing power source, flipping power source, upper pressing power source, and flipping limit cylinder are all electrically connected to the microcomputer control mechanism and are uniformly controlled by it.

[0007] After adopting the technical solution of this invention, the upper power source of the flipping mechanism works, and the upper pressure head pushes the filter paper (which has completed the first welding of the bottom of the filter paper to the plastic ring, and is a semi-finished filter element) out of the filter paper positioning mold and into the flipping mold. The flipping power source works, and drives the flipping mold and the filter paper to flip towards the flipping lower pressure power source until they reach its bottom, so that the position of the filter paper is reversed (the original bottom of the filter paper becomes the top, and the original top becomes the bottom). Then, the first flipping lower pressure power source works, and the second flipping lower pressure power source and the flipping lower pressure head are lowered into place. The filter paper positioning mold on the other side (without filter paper) also rotates to the bottom of this flipping mold. The second flipping lower pressure power source works, and the flipping lower pressure head presses the filter paper into the filter paper positioning hole of the filter paper positioning mold on the other side (i.e., material receiving process), thereby automatically completing the flipping and reversal of the filter paper, which fully prepares for the second welding of the bottom of the filter paper (the original top of the filter paper) and the plastic ring (both the top and bottom of the filter paper are welded with plastic rings). It eliminates the need for intermediate manual operation, boasts a high degree of automation, high work efficiency, robustness, reliability, and consistent processing quality, thereby significantly improving the quality of finished filter element components.

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0011] like Figure 1As shown, the present invention relates to an automatic flipping mechanism between plastic rings and filter paper in the production of filter elements. It includes a flipping frame 30. A primary flipping downward pressure power source 31 (a primary flipping downward pressure cylinder) is mounted on the upper part (front side) of the flipping frame 30. This primary flipping downward pressure power source 31 is connected to a secondary flipping downward pressure power source 33 (a secondary flipping downward pressure cylinder) via a downward pressure plate 32. A flipping downward pressure head 34 is connected below the secondary flipping downward pressure power source 33. A flipping power source 35 (a flipping cylinder) is mounted in the middle of the flipping frame 30 and is connected to a flipping mold 36. A flipping upward lifting power source 37 (a flipping upward lifting cylinder) is mounted on the lower part (back side) of the flipping frame 30 and is connected to an upward lifting head 38. The flipping mold 36 has positioning holes 39. Before flipping, the position of the flipping mold 36 corresponds to the position of the upward lifting head; after flipping, it corresponds to the position of the flipping downward pressure head. A tilting limit cylinder 40 is installed on the tilting frame 30 and on the side of the tilting mold 36. The tilting limit cylinder 40 is connected to a tilting limit block 43, which is adjacent to the tilting mold 36 (in a lateral position). The tilting power source 35 is connected to a handwheel 42 via a second screw 41. The handwheel 42 is mounted on the top of the tilting frame 30 and is used to adjust the tilting power source and the tilting mold.

[0012] like Figure 1 , Figure 2 As shown, the fully automatic welding machine for plastic rings and filter paper, which utilizes the automatic flipping mechanism between the plastic ring and filter paper of this invention, also includes a frame 1 and a turntable rotation mechanism 2. Turntable rotation mechanisms 2 (including a turntable 4, a mechanical control valve, an intermittent rotation divider, etc., controlling the intermittent rotation of the turntable) are mounted on both sides of the frame 1. An automatic flipping mechanism 3 between the two turntable rotation mechanisms 2 (a shared set) is mounted on the frame 1 and between the two turntable rotation mechanisms 2. A ring heating mechanism 6 and a pressing welding mechanism 7 are respectively mounted on the frame 1 and around the turntable 4. A microcomputer control mechanism 8 is also mounted on the frame 1. The turntable rotation mechanism 2, the automatic flipping mechanism 3 between the plastic ring and filter paper, the ring and filter paper tooling fixture 5 (with its upward pulling power source), the ring heating mechanism 6 (with its rotation power source and clutch cylinder), and the pressing welding mechanism 7 are all electrically connected to the microcomputer control mechanism 8 and uniformly controlled by it. The turntable rotation mechanism 2, the rubber ring heating mechanism 6, and the pressing and welding mechanism 7 are each located on the left and right sides of the frame. Alternatively, the rubber ring heating mechanism 6 can have two sets on each side of the frame (installed consecutively and adjacently for continuous heating and softening of the plastic rubber ring). The primary flipping pressing power source 31, the secondary flipping pressing power source 33, the flipping power source 35, the flipping upward lifting power source 37, and the flipping limit cylinder 40 are all electrically connected to the microcomputer control mechanism 8 for unified regulation.

[0013] After the turntable 4 rotates intermittently, the plastic ring filter paper fixture 5, which is used to place plastic rings and filter paper on one side of the frame, moves closer to the present invention and enters (the turntable stops rotating). The filter paper positioning mold of the plastic ring filter paper fixture and the filter paper on it (the bottom of the filter paper has been welded to the plastic ring, and it is a semi-finished filter element) are located between the flipping mold 36, the flipping upper push power source 37, and the upper push pressure head 38. The plastic ring placement wheel of the plastic ring filter paper fixture (which no longer has plastic rings) is located below the flipping upper push power source 37. At this time, the flipping upper push power source works and pushes the filter paper in the filter paper positioning mold out through the upper push pressure head into the positioning hole 39 of the flipping mold 36 (at the same time, the flipping limit cylinder drives the limit block to lock and limit the flipping mold, so that the flipping mold remains unchanged. After the filter paper is pushed out into place, the limit block retracts). Then, the flipping power source 35 operates, driving the flipping mold 36 and filter paper to flip towards the flipping secondary pressing power source 33 until they reach its bottom, thus reversing the orientation of the filter paper (the original bottom of the filter paper becomes the top, and the original top becomes the bottom). Afterwards, the flipping primary pressing power source 31 operates, using the lower pressing plate 32 to lower the flipping secondary pressing power source 33 and the flipping pressing head 34 into position. The rubber ring filter paper tooling fixture on the other side of the frame (which does not have filter paper on its filter paper positioning mold) also rotates to reach the bottom of this flipping mold. The flipping secondary pressing power source 33 operates, using the flipping pressing head 34 to press the filter paper (a semi-finished filter element) into the filter paper positioning hole of the filter paper positioning mold of the rubber ring filter paper tooling fixture on the other side (i.e., receiving the material), which fully prepares for the secondary welding of the bottom of the filter paper (the original top of the filter paper) and the plastic rubber ring in the next step. Next, the heating mechanism and the pressing welding mechanism on the other side weld the bottom of the filter paper (the original top of the filter paper) to the plastic ring (after heating). This fully automatic process completes the filter paper with plastic rings welded to both the top and bottom, and then a central tube is assembled to form the finished filter element assembly.
