Description

Mirror box flap turnover mechanism of mirror box boxing equipment

Technical Field

The invention belongs to the technical field of packaging equipment, and particularly relates to a mirror box flap folding mechanism of mirror box boxing equipment.

Background

The spectacle lenses need to be packaged in cartons after production. Because the lens is fragile, the paper box of design is to have both the fixed effect to the lens and the shock-absorbing function. For this purpose, a mirror box 20 as shown in fig. 6 has been designed, and unlike a general mirror box, the mirror box 20 has a lining 21 therein for fixing and damping.

Because this mirror box structure is complicated, in the past only can the manual mode carry out the dress piece, and people's frock piece needs a large amount of manual works, and on the one hand efficiency is lower, on the other hand causes to be stained with stain (for example fingerprint mark) on the lens easily, also can cause the damage of lens even.

After the lens box 20 in the state shown in fig. 6 is set up to the state shown in fig. 7, the flaps 22 are folded up after the lens is set up and the lining 21 is set up.

For this reason, there is a need for an apparatus capable of automatically packing a produced lens into a lens box to improve the lens packing efficiency and reduce damage to the lens.

Disclosure of Invention

The invention aims to solve the technical problem of providing a mirror box flap folding mechanism of a mirror box packing device, so as to overcome the defects in the prior art.

In order to solve the technical problems, the invention adopts the following technical scheme:

The scheme also comprises a support, a pressure head which can downwards approach the upper ends of the two rotating arms to enable the lower ends of the two rotating arms to be close to each other, a spring used for maintaining the lower ends of the two rotating arms to be close to each other, a chain wheel conveying belt used for driving the two rotating arms to move forwards to enable the flap of the mirror box to keep a folded state, and a top head used for enabling the lower ends of the two rotating arms to be far away from each other when the mirror box enters the mirror box closing mechanism, wherein the two rotating arms are arc-shaped rotating arms with the lower ends close to each other and can be folded into a flap, the side surfaces of the upper ends of the two rotating arms are respectively provided with a pulley, the middle parts of the upper end side surfaces of the two rotating arms are respectively provided with a handle part which is in rotary connection with the chain wheel conveying belt, the top contact parts are positioned at the lower ends of the rotating arms, two sides of the pressure head are respectively provided with a chute which is used for enabling the two top contact parts to be close to each other to be folded simultaneously when the pressure head moves downwards, the chain wheel conveying belt is fixed on the support, the top head is provided with the top head, the top head is provided with a handle which is used for gradually lifting the front upper end and the lower end of the pulley is close to each other to be far away from each other.

The two rotating arms are arc-shaped and obliquely arranged, and the upper ends of the two rotating arms are close to each other and the lower ends of the two rotating arms are far away from each other.

The pressure head is fixed on a connecting frame which is driven by an air cylinder capable of driving up and down.

The folding device can automatically fold the flaps of the lens box, and improves the lens packaging efficiency.

Detailed Description

As shown in fig. 1 to 3, a mirror box flap folding mechanism 100 of a mirror box packing apparatus for folding a flap 22 of a mirror box 20 in a state shown in fig. 7 includes two rotating arms 110 symmetrically disposed in front and rear of a side of a mirror box conveying mechanism 4 and simultaneously rotated reversely, and the two rotating arms 110 have a top contact portion 111 which is brought close to each other to fold the flap 22 of the mirror box 20 when the two rotating arms 110 are simultaneously rotated.

Specifically, the present embodiment further has a bracket 120, a pressing head 130 that can be brought down near the upper ends of the two rotating arms 110 to bring the lower ends of the two rotating arms 110 toward each other, a spring 140 for maintaining the lower ends of the two rotating arms 110 in a close state (close state see fig. 4), a sprocket conveyor 150 for driving the two rotating arms 110 to move forward to keep the flap 22 of the mirror box 20 in a folded state, and a head 160 (see fig. 5) for just keeping the lower ends of the two rotating arms 110 away from each other when the mirror box 20 enters the subsequent mirror box cover mechanism.

The two rotating arms 110 are arc rotating arms with lower ends close to the turnover flap 22, the two rotating arms are obliquely arranged, the upper ends are close to each other, the lower ends are far away from each other, the side surfaces of the upper ends of the two rotating arms 110 are respectively provided with a pulley 112, the middle parts of the two rotating arms are respectively provided with a handle 113 rotationally connected with the sprocket conveyor belt 150, and the top contact part 111 is positioned at the lower end of the rotating arm 110.

The ram 130 has on both sides a chute 131 for the two pulleys 112 to move away simultaneously as the ram 130 moves down to bring the two top contacts 111 closer together for flap folding, during which the spring 140 is gradually stretched from an initial state until the maximum distance it reaches at both ends, after which the distance between both ends is gradually shortened back to the initial state, thereby maintaining the lower ends of the two swivel arms 110 in the close state.

The ram 130 is fixed to the connection frame 170, and the connection frame 170 is driven by an air cylinder 180 that can be driven up and down.

The sprocket conveyor 150 is fixed to the bracket 120.

The top 160 has a top surface 161 with a front height and a rear height for gradually raising the pulley 112 so that the lower ends of the two rotating arms 110 are away from each other, wherein the top 160 has a block shape.

However, it will be appreciated by persons skilled in the art that the above embodiments are provided for illustration of the invention and not for limitation thereof, and that changes and modifications to the above described embodiments are intended to fall within the scope of the appended claims as long as they fall within the true spirit of the invention.
