Description

Technical Field

[0001] The utility model relates to the technical field of filter paper core shaping equipment, in particular to a position limiting dotting structure for filter paper core shaping. Background Art

[0002] As environmental pollution becomes increasingly severe, the level of respirable suspended particulate matter in the air is increasing. If these suspended particulate matter enters the cylinder of a car engine, they will form a large amount of colloidal matter and tiny wearable particles, affecting the complete combustion of the car engine. These particles then enter the cylinder and piston, causing wear of piston-related components and resulting in a decrease in engine performance. The function of the filter is to form a filtering barrier before air enters the cylinder, completely blocking these suspended particles from entering the cylinder while ensuring sufficient air intake, thus ensuring that the car engine's power is not lost.

[0003] At present, the inner core used in the filter is a cylindrical paper core folded into a zigzag structure with filter paper. In order to shape the zigzag structure of the filter paper, the filter paper core shaping equipment includes a paper feeding device and a shaping device. The paper feeding device extracts the paper strip from the filter paper roll and transports it to the shaping device at a uniform speed. The shaping device is formed with a shaping table and an origami structure is provided in the middle of the shaping table. The paper strip before shaping is guided from the input end of the shaping table to the origami structure. The origami structure is used to press the paper strip into supporting ridges at equal intervals. The supporting ridges are used to support and maintain the zigzag shape of the filter paper. The shaped paper strip is guided to the input end of the shaping table. Subsequently, the worker measures the length of the shaped paper strip with a ruler and cuts out the paper strip of the corresponding length. However, this measurement method requires the worker to have sufficient proficiency in measuring the length of the shaped paper strip. Because the shaped paper strip is elastic, the worker needs to maintain a constant force to apply pressure to the shaped paper strip and then measure it with a ruler to ensure that the length of the paper strip measured each time is consistent, which is relatively inconvenient.
