Description

Technical Field

[0001] The utility model relates to box cover production equipment, in particular to a box cover mouth strip bending and adsorption mechanism. Background Art

[0002] During the production process for wine boxes, gift boxes, and other boxes, one end of the lid must first be attached to the flap. The flap is then bent 90 degrees on both sides, forming a concave shape. The outer wall of the flap is then bonded to the inner wall of the box opening, completing the connection between the lid and the box. Traditionally, this process involves manually bonding the bent flap, with the lid attached, to the inside of the box. This method is labor-intensive and inefficient, making it difficult to achieve high-speed, high-quality production. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a box cover mouth strip bending and adsorption mechanism for solving the above-mentioned problem.

[0004] To this end, the present invention is implemented by adopting the following scheme:

[0005] The bending and adsorption mechanism of the box cover is characterized in that it includes a left movable arm and a right movable arm, and adsorption blocks are installed on the left and right movable arms. The adsorption block is provided with an adsorption port connected to its internal cavity, and the inner cavity of the adsorption block is connected to the negative pressure component. One end of the left movable arm is rotatably set on the left movable frame and connected to the first swing drive component, and one end of the right movable arm is rotatably set on the right movable frame and connected to the second swing drive component.

[0006] The first swing drive assembly includes a first cylinder, the cylinder body of the first cylinder is hinged on the left movable frame, and the piston rod of the first cylinder is hinged to the left movable arm. The second swing drive assembly includes a second cylinder, the cylinder body of the second cylinder is hinged on the right movable frame, and the piston rod of the second cylinder is hinged to the right movable arm.

[0007] The left movable frame is screwed to the left adjusting screw rotatably arranged on the frame, and the right movable frame is screwed to the right adjusting screw rotatably arranged on the frame. Both the left and right movable frames are provided with slide seats, and the frame is provided with slide rails matching the slide seats.

[0008] A plurality of adsorption blocks are arranged on the left movable arm and the right movable arm, the adsorption ports are arranged on the side walls of the adsorption blocks on the outer side, and the bottom of the lowest adsorption block is also provided with an adsorption port.

[0009] The above-mentioned technical solution has a folding adsorption mechanism for the box cover, which can adsorb and position the bent parts on both sides of the lip by setting an adsorption block. At the same time, by controlling the first and second movable arms to swing, the bent parts on both sides of the lip can be driven to swing inward and outward within a certain angle range. This can not only ensure that the lip is smoothly inserted into the box opening, but also realize the tight pressing and bonding between the lip and the inner wall of the box cover, and realizes automatic control throughout the process, which greatly reduces the labor intensity of workers and effectively improves production efficiency and quality.

[0012] Figure 2 This is a plan view of the utility model when adsorbing the mouth strip. DETAILED DESCRIPTION

[0013] As shown in the figure, the box cover bending and adsorption mechanism disclosed by the utility model includes a left movable arm 4 and a right movable arm 5. Adsorption blocks 10 are installed on both the left and right movable arms. The adsorption block 10 is provided with an adsorption port 12 connected to its internal cavity. The inner cavity of the adsorption block 10 is connected to the negative pressure component through a connecting nozzle 11. One end of the left movable arm 4 is rotatably set on the left movable frame 2 and is connected to the first swing drive assembly. Specifically, the first swing drive assembly includes a first cylinder 3, the cylinder body of the first cylinder 3 is hinged on the left movable frame 2, and the piston rod of the first cylinder 3 is hinged to the left movable arm 4. One end of the right movable arm 5 is rotatably set on the right movable frame 7 and is connected to the second swing drive assembly. The second swing drive assembly includes a second cylinder 6, the cylinder body of the second cylinder 6 is hinged on the right movable frame 7, and the piston rod of the second cylinder 6 is hinged to the right movable arm 5. Furthermore, the left movable frame 2 is screwed to the left adjusting screw 1 that is rotatably set on the frame, and the right movable frame 2 is screwed to the right adjusting screw 13 that is rotatably set on the frame. Both the left and right movable frames are provided with slides 9, and the frame is provided with slide rails 8 that cooperate with the slides 9. By controlling the rotation of the left and right adjusting screws, the left and right movable frames are driven to move, and then the spacing between the left and right movable arms is adjusted to adapt to the specifications of the mouth strip. Of course, in addition to the above-mentioned method of manually controlling the rotation of the adjusting screw for adjustment, it is also possible to connect a drive motor to the screw, and adjust the rotation of the screw by the motor, or use a common linear drive structure such as a gear rack and a ball screw structure to drive the movable frame to move. In this embodiment, a plurality of adsorption blocks 10 are arranged on the left movable arm 4 and the right movable arm 5, and the adsorption port 12 is provided on the side wall of the adsorption block 10 on the outer side, and an adsorption port is also provided at the bottom of the lowest adsorption block.

[0014] The working principle of the present invention is as follows: when the mouth strip is bonded to the box cover and the two sides of the mouth strip are bent 90 degrees, the straight portion 15 of the mouth strip is sucked by the suction port at the bottom of the suction block, the left bent portion 16 of the mouth strip is sucked and positioned by the suction block on the left movable arm 4, and the right bent portion 14 of the mouth strip is sucked and positioned by the suction block on the right movable arm 5. When the mouth strip is inserted into the opening of the wine box (the wine box can be controlled to move, and the suction mechanism can also be controlled to move. The suction mechanism can be set on the movable arm 4). The left and right movable arms are controlled to swing inwards to realize the inward swing of the left bending portion 16 and the right bending portion 14, so that the mouth strip can smoothly enter the wine box opening. After the mouth strip enters the wine box opening, the left and right movable arms are controlled to swing outwards to realize the outward swing of the left and right bending portions and press them against the inner side wall of the wine box opening. Glue is already adhered to the mouth strip or the wine box opening, and at this time, the wine box and the mouth strip can be bonded.

[0015] The structure of the present invention can adsorb and position the bent parts on both sides of the mouth strip by arranging adsorption blocks, and at the same time, by controlling the first and second movable arms to swing, the bent parts on both sides of the mouth strip can be driven to swing inward and outward within a certain angle range, which can not only ensure that the mouth strip is smoothly inserted into the opening of the wine box, but also realize the tight pressing and bonding between the mouth strip and the inner wall of the wine box cover, and realize automatic control throughout the process, which greatly reduces the labor intensity of workers and effectively improves production efficiency and quality.
