  • Patent number: 11833602
    Abstract: An edge band fine trimming mechanism of an edge banding machine includes a fixed seat, and a lateral feeler wheel, a top feeler wheel set and a scraper, which are disposed on the fixed seat. The lateral feeler wheel is rotatably disposed on the fixed seat. The top feeler wheel set includes a fixing member adjustably disposed on the fixed seat, and first and second top feeler wheels disposed separately, both rotatably disposed on the fixing member and located at a same predetermined height. The scraper is located between the lateral feeler wheel and the top feeler wheel set for trimming an edge of an edge band of a workpiece. Even though the workpiece has a hole, the scraper is positionally maintainable by the top feeler wheel set, that effectively reduces appearance defects of the end edge of the edge band caused in the edge trimming process.

  • Patent number: 10518435
    Abstract: A feeding system with numerically adjustable pneumatic cylinder speeds includes: a frame; an X-axis pneumatic cylinder; a Z-axis pneumatic cylinder; a feeding table connected to the pneumatic cylinders in order to be driven into motion in the X- and Z-axis directions; an X-axis detection module; a Z-axis detection module; a microcomputer; and a display screen electrically connected to the microcomputer. The microcomputer uses each detection module to determine the time interval between the instant at which the piston rod of the corresponding pneumatic cylinder passes the corresponding starting point and a subsequent instant at which the same piston rod passes the corresponding endpoint. The time intervals thus determined are defined as a duration of X-axis forward movement and a duration of Z-axis forward movement respectively. Both durations are displayed on the display screen.
