Description

Technical Field

[0001] The invention relates to the field of hardware plastic parts manufacturing, and in particular to a plastic filter element sealing and pressing device. Background Art

[0002] During the manufacturing process of the plastic filter element, it is necessary to fill the filter element with adsorption balls to absorb impurities, and then use a cap to seal it, such as Figure 3 As shown, the caps D are encapsulated at both ends of the filter element C to achieve the encapsulation of the adsorption balls. Since the filter element, adsorption balls and caps are small in size and light in weight, it is difficult to achieve automatic filling of the adsorption balls. The caps can only be installed manually after manual filling. Although the installed caps and filter element will not fall off, the gap between them is large, especially the edges cannot be sealed, resulting in gas leakage from the gap during the use of the filter element, and the filtering effect of the filter element is reduced; in order to solve the sealing problem, it is necessary to manually press the caps and filter element by hammering, which not only wastes manpower, but also the filter element will be knocked away or the fingers of the staff will be hammered during the hammering process, which brings great safety hazards to the staff. Summary of the invention

[0004] In order to solve the above-mentioned existing technical problems, the purpose of the present application is achieved by adopting the following technical solutions: a plastic filter element cap pressing device, including a base frame, a workbench arranged on the base frame, a hopper arranged on the workbench for placing plastic filter elements with caps, a horizontal conveying frame arranged on the workbench at the hopper outlet, a vertical feeding frame arranged on the workbench at the tail end of the horizontal conveying frame, a pressing mechanism arranged on the workbench at the bottom of the vertical feeding frame, a pushing cylinder arranged on the workbench for pushing the filter element in the vertical feeding frame into the pressing mechanism, and a control box arranged on the side of the base frame, and a lifting mechanism for pushing the filter element to the horizontal conveying frame is provided in the hopper. The control box controls the lifting mechanism in the hopper to push the plastic filter element with the cover to the horizontal conveyor rack. The filter elements are arranged horizontally on the horizontal conveyor rack in turn and sent to the vertical feed rack. The filter elements are arranged vertically in the vertical feed rack. The pushing cylinder at the bottom of the vertical feed rack sends the filter element at the bottom into the clamping mechanism. When the piston rod of the pushing cylinder is retracted, the filter elements in the vertical feed rack fall down in turn and enter the pushing cycle. After the filter element is sent into the clamping mechanism, the clamping mechanism is used to clamp the filter element cover, which can realize automatic clamping of the cover, reduce manpower waste, and eliminate safety hazards.

[0005] Preferably, the hopper is provided with a feed ramp and a discharge ramp, the transverse conveyor is arranged at the end of the discharge ramp, the lifting mechanism comprises a first lifting plate, a transition plate, and a second lifting plate which are arranged in sequence parallel to the discharge ramp, the transition plate is fixed in the hopper, the first lifting plate and the second lifting plate are slidably connected to the feed ramp, and the bottom of the workbench is provided with a lifting cylinder connected to the first lifting plate and the second lifting plate.

[0011] Preferably, a push plate for pushing the filter element into the clamp is provided on the piston rod of the push cylinder, and the push plate adopts an L-shaped structure. The front horizontal plate of the L-shaped structure is used to push the filter element, and the rear vertical plate of the L-shaped structure is used to limit the moving distance of the push plate.

[0012] Preferably, a connecting frame is provided on the side of the clamping clamp on the workbench, and a sensor for sensing the filter element falling off the clamping clamp is provided on the connecting frame. When the sensor cannot sense the normal falling of the filter element, it means that the filter element is stuck somewhere in the device, and the sensor sends a signal to the control box in time to shut down the device for maintenance to avoid damage to the device or the filter element.
