Description

Technical Field

[0001] This invention relates to machinery and equipment for manufacturing filters, and more specifically to a finished end cap filter paper discharge mechanism used 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 hollow cylindrical product (used to house the central tube). The end caps are annular and made of metal (or plastic), hence the name metal end caps (or plastic end caps). These 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 typically involves gluing or heating (using lamps or heating wires). Currently, non-woven fabric end caps are being used (replacing metal or plastic end caps). These end caps require ultrasonic welding, utilizing high-frequency ultrasonic friction to generate heat for feeding, welding (fusion), and unloading the non-woven fabric end caps and filter paper. This process is entirely manual or semi-automated, still requiring manual operation, resulting in low automation, poor 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 discharge mechanism for filter paper end caps that can automatically complete the discharge and receiving of finished filter paper, with a high degree of automation and no need for intermediate operation.

[0004] The objective of this invention is achieved through the following technical solution: an automatic discharge mechanism for end cap filter paper products, including a discharge rack connected to a discharge lifting power source, a discharge opening and closing power source mounted on one side of the discharge rack connected to a discharge opening and closing fork, a filter element ejection power source mounted on the other side of the discharge rack connected to a filter element ejection shaft, and a finished product receiving assembly mounted below the filter element ejection shaft.

[0005] The finished product receiving assembly includes a receiving frame, on which a receiving plate is movably connected. The receiving plate is connected to a receiving lifting power source. A pushing power source is mounted on the side of the receiving frame and is connected to a pushing plate. The pushing plate is located on the side of the receiving plate.

[0006] A second welding mechanism is installed on the side of the discharge rack. The second welding mechanism includes a welding frame, and a transducer lifting and pressing power source is installed on the top of the welding frame. A transducer and an ultrasonic welding head are connected to the transducer lifting and pressing power source. The ultrasonic welding head is connected to a cooler via a combination of a cool air cover and a cool air pipe connector. A filter element top plate is installed below the ultrasonic welding head, and the filter element top plate is connected to an upper power source.

[0007] By adopting the technical solution of this invention, the filter element, formed by welding the filter paper and non-woven fabric end cap together using a discharge opening and closing fork and a filter element ejection shaft, is ejected and discharged. The receiving plate then receives the material and lowers it onto a receiving rack. Finally, a pusher plate pushes the finished filter element out of the receiving rack, thus automatically completing the entire process of ejecting, discharging, receiving, and pushing the finished filter element. This eliminates the need for intermediate manual operation, resulting in a high degree of automation, high efficiency, robust reliability, and consistent processing quality, significantly improving the quality of the finished filter element.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1 to 4As shown, the present invention relates to an automatic discharge mechanism 8 for end cap filter paper products used in the production of filter elements. The mechanism includes a discharge rack 80 connected to a discharge lifting power source 81 (a discharge lifting cylinder). A discharge opening and closing power source 82 (a discharge opening and closing cylinder) is mounted on one side of the discharge rack 80. This power source 82 (via a discharge opening and closing fork mounting plate 86) is connected to a discharge opening and closing fork 83 (located above the discharge opening and closing assembly). A filter element ejection power source 84 (a filter element ejection cylinder) is mounted on the other side of the discharge rack 80. This power source 84 (via a filter element ejection mounting plate 87) is connected to a filter element ejection shaft 85. A finished product receiving assembly 89 is mounted below the filter element ejection shaft 85.

[0015] like Figure 1 , Figure 3 As shown, the finished product receiving assembly 89 includes a receiving frame 90 (mounted on the frame 1), and a receiving plate 91 (for receiving the finished filter element 88) is movably connected to the receiving frame 90. The receiving plate 91 is connected to a receiving lifting power source 92 (a receiving lifting cylinder, mounted on the frame). A pushing power source 93 (a pushing cylinder) is mounted on the side of the receiving frame 91. The pushing power source 93 is connected to a pushing plate 94, which is located on the side of the receiving plate 91. The filter paper end cap fixture 2, which has filter paper and non-woven fabric end caps (formed by secondary welding), rotates into place. The discharge lifting power source 81 starts, driving the discharge rack 80, the discharge opening and closing power source 82, and the filter element ejection power source 84 to descend into place. The discharge opening and closing power source 82 starts, driving the discharge opening and closing fork 83 and the filter element ejection power source 84 to start, driving the filter element ejection shaft 85. The discharge opening and closing fork 83 opens the filter paper end cap fixture 2, and the filter element ejection shaft 85 ejects the filter element product 88 formed by the secondary welding of filter paper and non-woven fabric end caps. The receiving plate 91 receives the material (the receiving lifting power source 92 starts and controls the rising into place), lowers it onto the receiving rack 90, and then the pushing power source 93 starts, driving the pushing plate 94 to push the filter element product from the receiving rack and send it to the filter element product box outside the machine frame.

[0016] like Figure 4As shown, the fully automatic ultrasonic welding machine for nonwoven end caps and filter paper used in this invention includes a frame 1 and a turntable rotation mechanism 10 (including a turntable and a turntable rotation control assembly, which are known technologies). Several sets of filter paper end cap tooling fixtures 2 are mounted on the periphery of the turntable of the turntable rotation mechanism 10. A support plate (fixed and non-rotating) is mounted on the turntable (its center position is supported by a support rod). A tooling fixture positioning assembly is mounted on the support plate. On the outer periphery of the turntable (on the frame, on the support plate, or outside the frame), corresponding to the positions of the filter paper end cap tooling fixtures 2 (above, below, or on the side), a filter paper feeding tooling opening and closing mechanism 4, a first nonwoven end cap feeding mechanism 5, a first welding mechanism 6 (including a cooling fan 67), a tooling fixture flipping mechanism 7, a second nonwoven end cap feeding mechanism 15, a second welding mechanism 16 (including a cooling fan 67), and an automatic end cap filter paper finished product discharge mechanism 8 (including a finished product receiving assembly 89) are sequentially mounted. The center position of the turntable does not rotate and is used for installation control. The turntable rotation mechanism 10, the filter paper feeding fixture opening and closing mechanism 4, the nonwoven fabric end cap first feeding mechanism 5, the first welding mechanism 6, the fixture flipping mechanism 7, the nonwoven fabric end cap second feeding mechanism 15, the second welding mechanism 16, and the end cap filter paper finished product automatic discharge mechanism 8 are all electrically connected to the microcomputer control mechanism 9 and are uniformly controlled by it. The nonwoven fabric end cap second feeding mechanism 15 has the same structure as the nonwoven fabric end cap first feeding mechanism 5, and the second welding mechanism 16 has the same structure as the first welding mechanism 6.

[0017] Through the automatic intermittent rotation of the turntable rotation mechanism 10 and its turntable, the filter paper is fed, clamped and positioned sequentially by the filter paper end cap tooling fixture 2 and the filter paper feeding tooling opening and closing mechanism 4. The non-woven fabric end cap first feeding mechanism 5 completes the feeding of the non-woven fabric end cap onto the filter paper (i.e., the initial feeding). The first welding mechanism 6 completes the welding of the filter paper and the non-woven fabric end cap. The tooling fixture flipping mechanism 7 completes the flipping of the filter paper end cap tooling fixture and flattens the filter paper. The non-woven fabric end cap second feeding mechanism 15 completes the feeding of the non-woven fabric end cap onto the flipped filter paper (i.e., the second feeding). The second welding mechanism 16 completes the second welding of the filter paper and the non-woven fabric end cap. The end cap filter paper finished product automatic discharge mechanism 8 completes the finished product discharge. Thus, the entire process of welding the filter paper and the non-woven fabric end cap to form the filter element finished product is completed automatically.

[0018] like Figure 4 , Figure 5As shown, a second welding mechanism 16 is installed on the side (previous process) of the discharge rack 80. The second welding mechanism 16 includes a welding frame 61 (mounted on a support plate). A transducer lifting and pressing power source 62 (a transducer lifting and pressing cylinder) is installed on the top of the welding frame 61. A transducer 63 (with a transducer protective cover 60) and an ultrasonic welding head 64 (connected to each other and located above the material discharge opening and closing assembly) are connected below the transducer lifting and pressing power source 62. The ultrasonic welding head 64 is connected to a cold air blower 67 through a combination of a cold air cover 65 and a cold air pipe 66 connector. A filter element top plate 68 is installed below the ultrasonic welding head 64. The filter element top plate 68 is connected to an upper lifting power source 69 (an upper lifting cylinder mounted on the frame 1). The filter paper end cap fixture 2, equipped with filter paper and non-woven fabric end caps, rotates into position. The transducer lifting and pressing power source 62 is activated, lowering the transducer 63 and ultrasonic welding head 64 into position. Simultaneously, the lifting power source 69 is activated, causing the filter element top plate 68 to rise, pressing against the bottom of the filter paper. The transducer then operates, and the ultrasonic welding head welds the non-woven fabric end cap to the filter paper. Then, the turntable rotates the filter paper end cap fixture 2 (with the filter paper and non-woven fabric end caps welded together) to the position of the automatic end cap filter paper finished product discharge mechanism 8.
