Description

Technical Field

[0001] The utility model relates to the technical field of hemming machines, and more specifically to an hemming device of the hemming machine. Background Art

[0002] The hemming machine includes vertical hemming on both sides, horizontal corner pinching and horizontal hemming. According to the Chinese Patent Database, the patent number is CN202321359546.7, and the utility model patent named "A hemming device of an hemming machine" discloses the following content: The utility model relates to an hemming device of an hemming machine, including a base, an upper and lower movable frame, a connecting bracket and a flanging assembly. A servo motor for driving the upper and lower movable frame to move up and down is arranged at the bottom of the base. The connecting bracket is linked with the upper and lower movable frame. The connecting bracket moves up and down with the upper and lower movable frame. A first driving mechanism for driving the flanging assembly to move left and right is fixed on the connecting bracket. The utility model patent with patent number CN201010115059.7 and name "A transverse hemming mechanism of a fully automatic edge banding machine" discloses the following content: an improved utility model of a transverse hemming mechanism of a fully automatic edge banding machine, the transverse hemming mechanism having a frame, a conveying platform being provided on the frame, a positioning beam and an hemming device being provided on both sides of the conveying platform, the positioning beam being able to move up and down relative to the conveying platform, the hemming device being arranged on the outer side of the positioning beam, the hemming device comprising a flanging base and a flanging plate, the flanging plate being installed on the flanging base, the flanging plate being able to move up and down on the flanging base and cooperating with the positioning beam, the flanging base being able to move left and right relative to the conveying platform on the frame.

[0003] However, these two folding methods have shortcomings: the first folding method uses an up-and-down moving frame to move upward, and then the flanging assembly moves forward to bend the facing paper inward, the flanging assembly presses down on the facing paper to complete the transverse hemming process, the up-and-down moving frame drives the connecting bracket and the flanging assembly to move upward, the first driving mechanism drives the flanging assembly to move backward, and finally reset; the second method uses a positioning beam to move downward to press the cardboard, and the flanging plate of the flanging device moves upward to bend the cardboard edge upward. At this time, the flanging device advances toward the conveying platform to fold the cardboard edge inward, and then the flanging plate is pressed down, and then the flanging device and the flanging plate perform reverse actions (i.e., 3 steps of moving up, retreating, and moving down to reset), and the positioning beam moves upward (i.e., a total of 8 steps in sequence). Both methods use the up-and-down and left-and-right movements of the flanging device, which affects the accuracy of the hemming, and affects the hemming quality for hemming materials with a shorter hemming width.
