[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention in any way.

[0031] Embodiment 1: refer to the attached Figure 1 As shown, the ear folding bonding device of a paper tray described in the utility model comprises a glue machine 1, an ear folding bonding machine 2 and a conveyor for conveying a paper tray 3. The ear folding bonding machine 2 is provided with a glue gun, and the adhesive used by the glue gun is provided by the glue machine 1.

[0032] like Figure 2-4 As shown, the ear-folding gluing machine comprises a fixed bracket 9, a lifter 11, a lift frame 4, a pressure rod cylinder 5, a pressure rod 13, a swing cylinder 6, a swing rod 7 and a glue gun 10. The lifter 11 is provided on the upper part of the fixed bracket 9, and the lifter 11 controls the vertical lifting of the lift frame 4. The pressure rod cylinder 5, the swing cylinder 6 and the glue gun 10 are all installed on the lift frame 4, and are lifted vertically with the lift frame 4.

[0033] Specifically, in this embodiment, a nut screw mechanism is used as the lift 11, and the lift frame 4 is connected to the nut of the nut screw mechanism. By turning the hand wheel 12 at the upper end of the screw, the lift frame 4 can be driven to lift vertically. Furthermore, a guide rail 15 is provided on one side of the lift 11, and a guide slider 14 on the guide rail 15 is connected to the lift frame 4 to ensure that the lift frame 4 can lift vertically.

[0034] In other embodiments, a lifting cylinder may also be used as the lifter.

[0035] The swing cylinders 6 are provided with two, which are located on the left and right sides in front of the lifting frame 4 and are connected to the lifting frame 4 through an L-shaped support plate. The output shaft of the swing cylinder 6 is connected to a swing rod 7. The swing axis of the swing cylinder 6 has a certain angle with the vertical direction, so that after the swing cylinder 6 swings, the swing rod 7 swings from outside to inside and from top to bottom, and folds the paper ears 8 inward.

[0036] Furthermore, the L-shaped support plate is installed on the lifting frame 4 by screws and nuts, and a plurality of connecting holes are provided on the lifting frame 4. By connecting the support plate with different connecting holes, the installation angle of the swing cylinder 6 can be adjusted to adapt to paper holders 3 of different sizes.

[0037] The cylinder body of the pressure rod cylinder 5 is installed obliquely at the rear of the lifting frame 4, and the piston rod of the pressure rod cylinder 5 extends obliquely downward. A clip is connected to the end of the piston rod, and the clip clamps the pressure rod 13. After the piston of the pressure rod cylinder 5 extends, the pressure rod 13 is pushed obliquely downward to the front paper support 3, and the paper support folding ears 8 exposed from the paper support 3 are folded downward by the two ends of the pressure rod, and the paper support folding ears 8 are pressed tightly against the rear wall of the paper support 3 to be bonded with the adhesive pre-sprayed by the glue gun 10.

[0038] Furthermore, the pressure rod is C-shaped, with its opening side facing the paper support.

[0039] The ear folding bonding method of the utility model is as follows: Figure 5-8 As shown, the paper tray 3 is transported forward on a conveyor (not shown in the figure). When it reaches the folding ear bonding machine 2, if it passes through the glue gun 10 first, the glue gun 10 sprays adhesive at a predetermined position on the rear wall of the paper tray. The glue spraying position 17 on the paper tray is as shown in FIG. Figure 6As shown. Then the paper tray 3 continues to move forward for a distance and is blocked by the positioning cylinder 16 on the side of the conveyor. The piston rod end of the positioning cylinder 16 is installed with a positioning block. The piston rod of the positioning cylinder 16 is extended to block the forward conveyance of the paper tray 3. At this time, the swing cylinder 6 is started, driving the swing rod 7 to fold the folding ear 8 of the paper tray inward, and then the pressure rod cylinder 5 is started, pushing the pressure rod 13 to fold the part of the folding ear 8 of the paper tray exposed from the rear wall 3 of the paper tray downward, so that it is bonded with the adhesive on the glue spraying position 17. After the folding ear is bonded, the piston rod of the positioning cylinder 16 is retracted, and the paper tray 3 continues to be conveyed forward.

[0040] As another ear folding bonding method, when the paper tray 3 arrives at the ear folding bonding machine 2, it first passes through the rocker bar 7 and the pressure bar 13, and finally reaches the glue gun 10. Before the paper tray 3 arrives at the glue gun 10, the rocker cylinder 6 and the pressure bar cylinder 5 are not started. When the glue spraying position 17 of the paper tray 3 enters the glue spraying range of the glue gun 10, the glue gun 10 sprays adhesive on the glue spraying position 17; then the conveyor reverses and transports the paper tray 3 in the opposite direction to the position of the rocker bar 7 and the pressure bar 13. At this time, the positioning cylinder 16 pushes the positioning block to extend to position the paper tray 3; then, according to the ear folding bonding action described above, the rocker bar 7 and the pressure bar 13 fold the paper tray ear 8 in turn to complete the bonding.

[0041] Embodiment 2: The difference between this embodiment and embodiment 1 is that in this embodiment, the glue gun, the swing cylinder and the pressure rod cylinder are all arranged on a frame with a fixed height, and the folding ears of paper trays of uniform size are bonded. The other structures and the folding ears bonding process are the same as those in embodiment 1.

[0042] It is understandable that when implementing the present invention, other linear telescopic mechanisms such as electric push rods or hydraulic cylinders can be used to replace the pressure rod cylinder and the positioning cylinder, and rotating motors such as servo motors can be used to replace the swing cylinder, both of which can achieve the purpose of automatically folding and gluing the paper tray of the present invention.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can be modified or replaced by equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
