Detailed Description
The utility model is described in further detail below with reference to the drawings and examples, which are not intended to be limiting.
Embodiment 1 referring to fig. 1, the ear folding and bonding device of the paper holder comprises a glue machine 1, an ear folding and bonding machine 2 and a conveyor for conveying the paper holder 3, wherein a glue gun is arranged on the ear folding and bonding machine 2, and bonding glue used by the glue gun is provided by the glue machine 1.
As shown in fig. 2-4, the ear folding and gluing machine comprises a fixed bracket 9, a lifter 11, a lifter frame 4, a pressing rod cylinder 5, a pressing rod 13, a swinging cylinder 6, a swinging rod 7 and a glue gun 10. The upper part of the fixed bracket 9 is provided with the lifter 11, and the lifter 11 controls the lifting frame 4 to vertically lift. The compression bar cylinder 5, the swinging cylinder 6 and the glue gun 10 are all arranged on the lifting frame 4 and vertically lift along with the lifting frame 4.
Specifically, in this embodiment, a nut screw mechanism is used as the lifter 11, the lifter frame 4 is connected with a nut of the nut screw mechanism, and the lifter frame 4 can be driven to vertically lift by rotating a hand wheel 12 at the upper end of the screw. Further, a guiding sliding rail 15 is further arranged on one side of the lifter 11, and a guiding sliding block 14 on the guiding sliding rail 15 is connected with the lifter frame 4, so as to ensure that the lifter frame 4 can vertically lift.
In other embodiments, a lift cylinder may also be employed as the lift.
The swing cylinders 6 are arranged at two sides and are positioned at the left side and the right side in front of the lifting frame 4 and are connected to the lifting frame 4 through L-shaped support plates, an output shaft of each swing cylinder 6 is connected with a swing rod 7, and a certain included angle is formed between the swing axis of each swing cylinder 6 and the vertical direction, so that after the swing cylinders 6 swing, the swing rods 7 swing obliquely from outside to inside and from top to bottom, and the paper support ears 8 are folded inwards.
