Description

Technical Field

[0001] This invention relates to machinery and equipment for manufacturing filters, and more specifically to a tooling fixture for rubber ring filter paper 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 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 finally unloading the finished product. This process is either fully manual or semi-automated, and manual operation is still required in between. The automation level is low, the work efficiency is poor, and the processing quality is difficult to guarantee. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a rubber ring filter paper tooling fixture that can sequentially complete the processes of filter paper feeding and clamping, rubber ring feeding, and rubber ring lifting and lowering, 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: a rubber ring filter paper tooling fixture, comprising a frame and a turntable, with a mold frame mounted on the periphery of the turntable. A filter paper positioning mold is mounted on the upper part of the mold frame, and a rubber ring positioning mold is mounted on the lower part. The filter paper positioning mold has filter paper positioning holes. The rubber ring positioning mold is equipped with rubber ring placement wheels and heating rotating wheels that are vertically connected and correspond to the positions of the filter paper positioning holes. Several heating rotating wheels are connected by a synchronous belt to achieve synchronous rotation. The rubber ring positioning mold is connected to an upward pulling power source. A microcomputer control mechanism is also mounted on the frame, and the upward pulling power source is electrically connected to the microcomputer control mechanism for unified control.

[0005] A lifting guide rail assembly, connecting to the rubber ring positioning mold, is provided on the mold frame, on the side between the filter paper positioning mold and the rubber ring positioning mold. A rubber ring heating mechanism is mounted on the frame, around the turntable. This mechanism includes a heating frame; a heating source is mounted on the upper middle part of the heating frame via a heating source bracket; and a drive wheel and a rotational power source are mounted on the lower part of the heating frame via a rotational power source bracket, connected vertically to each other. A clutch cylinder is also mounted on the heating frame. This clutch cylinder is connected to the rotational power source bracket via a clutch rod and a clutch guide rail. The rotational power source and clutch cylinder are electrically connected to a microcomputer control mechanism for unified regulation. The heating source bracket is connected to a knob via a first screw, which is mounted on the top of the heating frame.

[0006] By adopting the technical solution of this invention, the filter paper and plastic ring are sequentially positioned by the filter paper positioning mold and the plastic ring positioning mold through the automatic intermittent rotation of the turntable. The plastic ring heating mechanism softens the plastic ring, and the upward power source lifts the plastic ring positioning mold, thus preparing it for the downward welding mechanism to weld the bottom of the filter paper to the softened plastic ring. This automatically completes the entire process of filter paper and plastic ring positioning, plastic ring heating and softening, and upward lifting. It eliminates the need for manual operation, boasts a high degree of automation, high efficiency, robust reliability, and consistent processing quality, significantly improving the quality of the finished filter element assembly.

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

[0011] like Figure 1 , Figure 2 As shown, the present invention relates to a rubber ring filter paper tooling fixture 5 used in the production of filter elements. The machine includes a frame 1 and a turntable 4. A mold frame 50 (several evenly arranged) is mounted around the perimeter of the turntable 4. A filter paper positioning mold 51 is mounted on the upper part of the mold frame 50, and a rubber ring positioning mold 52 (facing outwards in the same direction) is mounted on the lower part. The filter paper positioning mold 51 has several filter paper positioning holes 53. The rubber ring positioning mold 52 is equipped with rubber ring placement wheels 54 (on the upper part) and heating rotating wheels 55 (several on the lower part, connected by a synchronous belt 56 to achieve synchronous rotation) that correspond to the positions of the filter paper positioning holes and are interconnected vertically. The rubber ring positioning mold 52 is connected to an upward pulling power source 57 (mounted on the filter paper positioning mold, which is an upward pulling cylinder). A lifting guide rail assembly 58, connected to the rubber ring positioning mold 52, is provided on the mold frame 50, on the side between the filter paper positioning mold 51 and the rubber ring positioning mold 52.

[0012] like Figure 1 , Figure 3 As shown, a rubber ring heating mechanism 6 is installed on the frame 1 and around the turntable 4. The rubber ring heating mechanism 6 includes a heating frame 60. A heating source 63 (a heating lamp) is installed on the upper middle part of the heating frame 60 via a heating source bracket 61. A drive wheel 64 (at the upper position) and a rotary power source 65 (at the lower position, a rotary motor) are installed on the lower part of the heating frame 60 via a rotary power source bracket 62. A clutch cylinder 66 is also installed on the heating frame 60. The clutch cylinder 66 is connected to the rotary power source bracket 62 via a clutch rod 67 (connected to the clutch cylinder 66) and a clutch guide rail 68 (connected to the rotary power source bracket 62). The clutch cylinder drives the clutch rod and the clutch guide rail to move back and forth, thereby displacing the rotary power source bracket to control whether the drive wheel 64 on the rotary power source 65 is engaged with the heating rotary wheel 55 or the synchronous belt 56 of the rubber ring filter paper tooling fixture 5. The heating source bracket 61 is connected to the knob 59 via the first screw 69. The knob 59 is mounted on the top of the heating frame 60. The rotation of the knob drives the first screw to rotate, thereby raising and lowering the heating source bracket and the heating source.

[0013] like Figure 1As shown, the fully automatic welding machine for plastic rubber rings and filter paper used in the rubber ring filter paper tooling fixture of the present invention has a turntable rotation mechanism 2 (including mechanical control valves, intermittent rotation dividers, etc., controlling the intermittent rotation of the turntable 4) installed on both sides of the frame 1. An intermediate flipping mechanism 3 (a shared set) is installed on the frame 1 and between the two turntable rotation mechanisms 2. A rubber ring heating mechanism 6 and a pressing welding mechanism 7 are respectively installed on the frame 1 and around the turntable 4. A microcomputer control mechanism 8 is also installed on the frame 1. The turntable rotation mechanism 2, the intermediate flipping mechanism 3, the rubber ring filter paper tooling fixture 5 (with its upper pull power source 57), the rubber ring heating mechanism 6 (with its rotation power source 65 and clutch cylinder 66), and the pressing welding mechanism 7 are all electrically connected to the microcomputer control mechanism 8 and are uniformly controlled by it. The turntable rotation mechanism 2, the rubber ring heating mechanism 6, and the pressing and welding mechanism 7 are one set each on the left and right sides of the frame. The rubber ring heating mechanism 6 can also be two sets each on the left and right sides of the frame (installed continuously and adjacently to facilitate continuous heating and softening of the plastic rubber ring).

[0014] First, filter paper is placed into the filter paper positioning hole 53 of the filter paper positioning mold 51 on one side of the frame, and plastic ring is placed on the ring placement wheel 54. The filter paper fixture 5 is moved closer to the ring heating mechanism 6 by the intermittent rotation of the turntable 4 (the turntable stops rotating). The filter paper positioning mold 51 and filter paper are above the heating source support 61 and heating source 63, the ring placement wheel 54 and plastic ring are below the heating source 63, and the heating rotating wheel 55 or synchronous belt 56 is connected to the drive wheel 64. The rotating power source 65 drives the drive wheel 64 to rotate the heating rotating wheel 55 and the ring placement wheel 54, so that the plastic ring on the ring placement wheel is evenly heated and softened by the heating source. After the plastic ring is heated and softened, the clutch cylinder 66 operates, driving the clutch lever 67, which in turn causes the rotary power source 65 and drive wheel 64 on the rotary power source bracket 62 to retract via the clutch guide rail 68, separating the drive wheel 64 from the synchronous belt 56 and the heated rotary wheel 55. Then, the turntable continues to rotate intermittently, bringing the plastic ring filter paper fixture 5 closer to and into the downward pressing welding mechanism 7 (the turntable pauses its rotation). The downward pressing welding mechanism 7 connects the softened plastic ring on the plastic ring placement wheel with the bottom of the filter paper in the filter paper positioning mold, automatically welding the plastic ring and the bottom of the filter paper together. Then, the upward pulling power source 57 lowers the plastic ring positioning mold 52 back to its original position.
