Description

Technical Field

[0001] This utility model relates to air filter processing, specifically to an air filter laser trimming machine. Background Technology

[0002] During the air filter processing, it is necessary to trim the edge of the air filter blank rubber ring (injection molding residue). Currently, the trimming work is done manually by holding the air filter blank and using a conical trimming knife. This is labor-intensive and the trimming quality is inconsistent, making it impossible to guarantee the trimming quality. Utility Model Content

[0003] This invention proposes an air filter laser trimming machine, which aims to solve the above-mentioned problems.

[0004] An air filter laser trimming machine includes a frame with a platform on the frame; the trimming machine also includes a material holder and a laser generator. The material holder is fixedly connected to the platform, and a horizontal / vertical moving device is installed on the platform. The laser generator is installed on the horizontal / vertical moving device and is suspended above the material holder. The horizontal / vertical moving device drives the laser generator to move horizontally or vertically.

[0005] An air filter blank is placed on a material holder. A laser generator emits a laser beam, which moves laterally or longitudinally. The laser cuts and trims the edge of the air filter blank.

[0006] Further refining the above technical solution, the transverse / longitudinal moving device includes a crossbeam, a longitudinal driving mechanism, and a transverse driving mechanism. The crossbeam is mounted on a platform and connected to the platform via a slider and a slide rail. The longitudinal driving mechanism is mounted on the platform and connected to the crossbeam. The longitudinal driving mechanism drives the crossbeam to move longitudinally. The crossbeam is mounted above the material seat. The laser generator is mounted on the crossbeam and connected to the crossbeam via a slider and a slide rail. The transverse driving mechanism is mounted on the crossbeam and connected to the laser generator. The transverse driving mechanism drives the laser generator to move laterally.

[0007] Further refining the above technical solution, both the longitudinal drive mechanism and the transverse drive mechanism are composed of a motor connected to pulleys and belts.

[0008] Further refining the above technical solution, the material holder includes an aluminum plate, which is suspended on a platform and has a contour groove on it to accommodate the air filter blank; the air filter blank is placed in the contour groove, and its edge to be trimmed is supported on the aluminum plate of the material holder; laser trimming is accompanied by the generation of high temperature, and the suspended aluminum plate has heat dissipation.

[0009] Laser cutting involves high-temperature burning of rubber, which produces odorous fumes. Therefore, the trimming machine is designed to include a smoke / odor removal device to remove the odorous fumes. The specific design includes a smoke / odor removal device consisting of a hood, two axial flow fans, and an exhaust pipe. The hood is installed on a platform on one side of the material seat, with an opening facing the material seat. The two axial flow fans are installed on the platform at the opening of the hood. The exhaust pipe is connected to the hood, and the fans may be installed on it.

[0010] Two axial flow fans are located at the opening of the shroud, facing the suspended aluminum plate, which can accelerate the airflow above and below the suspended aluminum plate, resulting in better heat dissipation.

[0011] The advantages of this utility model are that it has a reasonable design and simple structure. It uses laser for trimming and is supplemented by an automatic control system (based on PLC or single-chip microcomputer, conventional automatic control technology, which will not be described in detail in this patent application). It can realize automatic trimming of air filter blanks (of course, the loading and unloading of air filter blanks still need to be done manually), which reduces labor intensity and achieves high trimming quality.
