Description

Technical Field

[0001] The utility model relates to the technical field of automobile air filter production, in particular to a PLC device used in the production process of automobile air filters. Background Art

[0002] There's a lot of dust suspended in the air, primarily composed of silica, a substance harder than metal. Installing an air filter can reduce wear on components like cylinders, pistons, and piston rings. Without an air filter, cylinder wear in a car increases sevenfold, piston wear increases threefold, and piston ring wear increases eightfold. Therefore, modern car engines all have air filters installed near the carburetor (or the intake control device in electronic fuel injection engines).

[0003] PLC can be divided into the following three categories: (1) Monolithic PLC: Monolithic PLC is a PLC that integrates the power supply CPU, input / output interface and other components into a single chassis, with the characteristics of compact structure, small size and low price; (2) Modular PLC: Modular PLC is a PLC that makes each component of the PLC into several separate modules, such as CPU module, input / output module, power module (some are included in the CPU module) and various functional modules; (3) Stacked PLC: Combining the characteristics of monolithic PLC and modular PLC, it is called stacked PLC. The CPU, power supply, input / output interface, etc. of the stacked PLC are also independent modules, but they are connected by cables, and the modules can be stacked layer by layer. In this way, the system can not only be flexibly configured, but also be made compact. Monolithic PLC is a commonly used PLC controller.

[0004] Existing air filters are produced using a production line, which requires a PLC controller for control. Workers can use the PLC controller to control the production line process. However, the existing PLC controller is mainly fixed on the control cabinet, and the position of the PLC controller is not convenient to adjust, and it is not convenient to adjust it in real time according to the production process.

[0005] Therefore, those skilled in the art provide a PLC device for use in the production process of automobile air filters to solve the problems raised in the above background technology. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In the present invention, slots in opposite directions are provided on both sides of the slide rail, and the splines are mounted on the housing. The splines cooperate with the slots, and the splines on one side can only move in one direction on the corresponding slot and cannot move in the opposite direction. This facilitates the adjustment of the housing position and the position of the PLC controller can be adjusted as needed.

[0016] 2. In the present invention, a movable groove is provided on the housing, so that the moving block can move inside the movable groove. As the position of the moving block is adjusted, the spline can move accordingly. The spline can move away from the slot, which can facilitate unidirectional movement of the PLC controller.
