Description

Technical Field

[0001] The utility model relates to the technical field of filter element assembly, in particular to single-pressure filter element assembly equipment. Background Art

[0002] Single-press filter element assembly equipment is typically used to assemble filter element components into a complete filter. Typically consisting of a frame, press-fit system, clamping device, and control system, the equipment boasts a compact design for easy operation and maintenance. The single-press design applies uniform pressure hydraulically or mechanically to ensure a seal between the filter element and the housing. Equipped with a PLC control system, it enables automated operation, including pressure control, time setting, and fault detection, improving production efficiency. The equipment can also incorporate a seal detection function, ensuring a good seal after assembly by applying pressure or detecting gas leaks.

[0003] Chinese patent CN218687167U discloses "a tool for assembling a filter element", which places the filter element shell in the bottom shell seat, then controls the second motor to drive the rotating seat to rotate, thereby rotating the gluing head to the top of the bottom shell seat, then starts the first motor to drive the bottom shell seat to rotate, and at the same time starts to deliver glue to the gluing head through the glue pipe to extrude the glue, and then wraps it around the filter element shell, then starts the second motor to rotate the rotating seat to one side, and then starts the hydraulic lifter to descend, thereby driving the filter element barrel on the mounting seat to be stuck on the bottom shell seat, and then insert the filter paper into the mounting seat, and then starts the hydraulic lifting column to rise, and then starts the second motor to rotate the rotating seat, thereby rotating the gluing head to the top of the filter paper, and then starts the first motor to rotate, thereby driving the filter element barrel on the bottom shell seat to rotate, thereby driving the filter paper in the filter element barrel to rotate, and at the same time delivers glue to the gluing head through the glue pipe for gluing, and then places the filter paper sealing shell above the filter paper core, and then starts the hydraulic extrusion column to squeeze the extrusion seat downward, so that the extrusion seat squeezes and fixes the filter element.

[0004] Improper operation when activating the hydraulic squeeze rod and pressing downward can result in hand injuries. This is primarily due to the working principle of the hydraulic system. The hydraulic squeeze rod uses the pressure of the hydraulic oil to generate a powerful downward thrust, capable of exerting a large force in a short period of time. If the operator is not careful during the pressing process, their hand may be squeezed between the filter element and the squeeze seat, resulting in pinching or other serious injuries.

[0005] In view of this, we propose a single-pressure filter element assembly equipment. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1-6 As shown, the utility model provides a technical solution: a single-pressure filter element assembly device, including a base frame 1, the top of the base frame 1 is fixedly connected to a support column 2, the outer wall of the support column 2 is fixedly connected to a middle connecting plate 3, the top of the support column 2 is fixedly connected to a top support plate 4, and the bottom of the top support plate 4 is provided with a protective mechanism 5, the protective mechanism 5 includes: a telescopic motor 51, the outer shell of the telescopic motor 51 is fixedly connected to the inner wall of the top support plate 4, the output shaft of the telescopic motor 51 is fixedly connected to a transverse driving rod 52, the outer wall of the support column 2 is fixedly connected to a fixing frame 53, and the outer wall of the fixing frame 53 is fixedly connected to a fixing ring 54; a frame-shaped member 55, an annular rotating groove 56 is provided on the surface of the frame-shaped member 55, an annular slide groove 57 is provided on the outer wall of the frame-shaped member 55, a vertical slide groove 58 is provided on the outer wall of the frame-shaped member 55, and the bottom of the frame-shaped member 55 is fixedly connected to a protective rod 59; the bottom of the top support plate 4 is provided with a delay mechanism 6. Place the filter element to be assembled on the top of the base frame 1, then turn on the output shaft of the telescopic motor 51 to drive the transverse drive rod 52 to move downward. The transverse drive rod 52 contacts the annular groove 57, causing the frame 55 to rotate half a circle, and the frame 55 drives the protective rod 59 to rotate half a circle.

[0028] The delay mechanism 6 includes a spring 1 61, one end of which is fixedly connected to the bottom of the output shaft of the telescopic motor 51, the other end of the spring 1 61 is fixedly connected to a pressing piece 63, the top of the pressing piece 63 is fixedly connected to a connecting sleeve 62, the outer wall of the pressing piece 63 is provided with an annular groove 64, the top of the pressing piece 63 is provided with an annular inclined surface 65, the top of the middle connecting plate 3 is fixedly connected to a fixing plate 66, the outer wall of the fixing plate 66 is fixedly connected to one end of a spring 2 67, the other end of the spring 2 67 is fixedly connected to a positioning block 68, and the outer wall of the positioning block 68 is fixedly connected to a positioning rod 69. The output shaft of the telescopic motor 51 presses the pressing piece 63 downward through the spring 1 61. At this time, the arc surface of the positioning block 68 contacts the annular groove 64, so that the pressing piece 63 cannot move downward at this time until the protective rod 59 rotates half a circle. At this time, the horizontal drive rod 52 enters the vertical slide groove 58, and the horizontal drive rod 52 contacts the connecting sleeve 62 downward. The connecting sleeve 62 drives the pressing piece 63 downward. At this time, the positioning block 68 moves toward the direction of the fixed plate 66. At this time, the pressing piece 63 moves downward to extrude and install the filter element, so that the pressing piece 63 will be driven downward only after the protective rod 59 rotates half a circle.

[0029] The outer wall of the fixing ring 54 is rotatably connected to the inner wall of the annular groove 56, so that the frame 55 can rotate freely under the action of the fixing ring 54. The middle part of the frame 55 is hollow, so that the output shaft of the telescopic motor 51 can move up and down freely. A base is provided on the top of the base frame 1 for supporting the installation of the filter element. A circular through hole is provided on the surface of the middle connecting plate 3 so that the protective rod 59 will not be affected when it rotates. There are four support columns 2, and the four support columns 2 are symmetrically arranged in pairs, which play a role of fixed support.

[0030] The inner wall of the connecting sleeve 62 is slidably connected to the output shaft of the telescopic motor 51, and the outer wall of the positioning rod 69 is slidably connected to the inner wall of the fixing plate 66, so that the positioning rod 69 drives the positioning block 68 to slide back and forth stably. The surface of the positioning block 68 away from the positioning rod 69 is arc-shaped. When the pressing member 63 moves downward, the positioning rod 69 will first contact the inner side of the annular groove 64, and the pressing member 63 will not move downward at this time. The transverse drive rod 52 penetrates the outer wall of the frame member 55.

[0031] When the single-pressure filter element assembly device of the present invention is in use, the filter element to be assembled is placed on the top of the base frame 1, and then the output shaft of the telescopic motor 51 is turned on to drive the transverse drive rod 52 to move downward. The transverse drive rod 52 contacts the annular slide groove 57, causing the frame part 55 to rotate half a circle, and the frame part 55 drives the protective rod 59 to rotate half a circle. If the staff's hand has not been retracted at this time, it will be pushed away by the protective rod 59, avoiding hand injuries to the staff.

[0032] The output shaft of the telescopic motor 51 presses the pressing member 63 downward through the spring 1 61. At this time, the arc surface of the positioning block 68 contacts the annular groove 64, so that the pressing member 63 cannot move downward at this time until the protective rod 59 rotates half a circle. At this time, the horizontal drive rod 52 enters the vertical slide 58, and the horizontal drive rod 52 contacts the connecting sleeve 62 downward. The connecting sleeve 62 drives the pressing member 63 downward. At this time, the positioning block 68 moves toward the fixed plate 66. At this time, the pressing member 63 moves downward to squeeze and install the filter element, so that the pressing member 63 will not be driven downward until the protective rod 59 rotates half a circle, ensuring that the staff's hand cannot touch the pressing member 63 before the protective rod 59 is completely pushed open. This design reduces the possibility of accidental pinching through isolation in time and space, provides additional safety protection, and further avoids the risk of hand injury. The device only uses a fixed pressure application method to press the filter element, so it belongs to a single-pressure filter element assembly device.
