Description

Technical Field

[0002] Common packaging boxes for medicines, food, stationery, cigarettes, handicrafts, soft drinks, washing supplies, small hardware products, etc. are used as outer packaging to ensure the safety of products during transportation and improve the grade of products. At present, there are two main types of packaging boxes on the market, one is foldable and the other is non-foldable. Non-foldable packaging boxes cannot change their appearance after the box is formed by gluing, and they are always in a three-dimensional state. Their disadvantage is that they cannot be folded after the box is formed, and the volume cannot be reduced during storage and transportation. They occupy a large space, and the space utilization efficiency is low, which will increase transportation and storage costs. Foldable packaging boxes can change the packaging box from a three-dimensional state to a flat state by folding one or several of its components, or change the packaging box from a flat state to a three-dimensional state. By folding to change its appearance, it can be folded into a flat state for storage and transportation, which greatly reduces the occupied space, improves the space utilization efficiency, and reduces transportation and storage costs. Traditional foldable packaging boxes are produced with soft materials according to the folding structure, and are assembled into three-dimensional shapes by snapping, which is economical and affordable, but the packaging protection effect and three-dimensional forming effect are poor; existing foldable packaging boxes are produced with hard materials according to the folding structure, and are connected into three-dimensional shapes by pushing and leaning the folding ears to form magnets, which can withstand greater external impact forces, have good packaging protection effects, good hardness of the box material, and good three-dimensional forming effects.

[0003] The foldable packaging box (folding box) includes a leather shell and two side panels connected to the leather shell. The folding ears at both ends of the side panels are bonded to the leather shell, which is convenient for the folding box to change from a flat state to a three-dimensional state, and to connect the three-dimensional molding with magnets, or change the three-dimensional state to a flat state, thereby reducing the occupied space and facilitating storage and transportation. In the existing production process, the side panels of the folding box can be automatically bonded to the leather shell by a device, but the folding ears on the side panels need to be folded and then bonded, mainly by manual bonding, with low bonding accuracy, low assembly efficiency of the folding ears of the folding box, and high cost.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0046] See also Figure 1-9 The present invention discloses a folding ear assembly device for a folding box, comprising a conveying mechanism 1 for conveying a leather shell connected to the bottom edge of a side panel, a forming mechanism 2 for three-dimensionally forming a folding box, and a pressing mechanism 3 for pressing the folding ear bonding position of the side panel; the forming mechanism 2 comprises a box body mold 21, two groups of edge-supporting components 22 connected to the box body mold 21 and symmetrically arranged, and a first driving component 23 for driving the box body mold 21 to move, the forming mechanism 2 is arranged above the conveying mechanism 1, so that the first driving component 23 drives the box body mold 21 to connect with the leather shell conveyed by the conveying mechanism 1, and the two groups of edge-supporting components 22 bend the side panel to make the side panel close to the box body mold 21; the pressing mechanism 3 comprises two symmetrically arranged pressing members 31 and a pressing drive 32 for driving the two pressing members 31 to move, the pressing mechanism 3 is arranged below the conveying mechanism 1, and the forming mechanism 2 is located above the pressing mechanism 3, and the pressing drive 32 drives the two pressing members 31 to press the folding box moved to the pressing station.

[0047] In this way, the first driving component 23 drives the box body mold 21 to connect with the skin shell transmitted by the conveying mechanism 1, and the two sets of edge support components 22 bend the side panels and approach the box body mold 21, so that the skin shell and the side panels are three-dimensionally formed, and then the first driving component 23 drives the pressing station, and the pressing drive 32 drives the two pressing parts 31 to press the folded ear bonding parts of the side panels, so that the folded ear bonding parts with glue are firmly bonded, and the folded ears are automatically bonded by machinery, thereby improving production efficiency and product precision, and reducing defective rate and production cost.

[0048] See also Figure 2-4In some embodiments, the corners of the box body mold 21 are provided with vacuum suction cups 211 for sucking the skin, side panels and folded ears on the side panels. The bottom surface and two adjacent exposed side surfaces of the vacuum suction cups 211 can suck close objects. The vacuum suction cups 211 suck the skin, side panels and folded ears on the side panels that are pushed close to the box body mold 21 by the hedging assembly 22. When the box body mold 21 continues to move downward under the drive of the first driving assembly 23, the hedging assembly 22 can be reset without colliding with the clamping mechanism 3.

[0049] See also Figure 4 In some embodiments, the side support assembly 22 includes two symmetrically arranged side support members 221, a folding ear member 222 connected to the side support member 221, and a side support drive 223 driving the side support member 221 to move. The side support member 221 and the folding ear member 222 are arranged at right angles, and the side support drive 223 is connected to the box body mold 21. Among them, the present invention takes the side support drive 223 using a cylinder as an example. In practical applications, other driving devices can also be used. The side support member 221 and the folding ear member 222 are arranged at right angles. When the side support drive 223 pushes the side plate to approach the box body mold 21, the folding ear member 222 first contacts the side plate. After the side plate is close to the box body mold 21, the folding ear member 222 presses the folding ear on the side plate to the adjacent side of the box body mold 21. Finally, the folding ear member 222 and the side support member 221 jointly press the side plate and the folding ear on the side plate onto the box body mold 21. The edge support drive 223 is connected to the box body mold 21, and the positions of the two are relatively fixed during the working process, which can ensure that the movement of the edge support member 221 and the folding ear member 222 just fits the side panel and the folding ears on the side panel into the box body mold 21, avoiding errors in the working process.

[0050] Specifically, the edge-supporting member 221 is provided with an edge-supporting roller 2211, and the folding ear member 222 is provided with an folding ear roller 2221, so as to reduce the friction on the side plate and the folding ears on the side plate during the edge-supporting operation and avoid damaging the appearance. The edge-supporting roller 2211 is arranged vertically, and the folding ear roller 2221 is arranged horizontally. Combined with the movement direction of the edge-supporting drive 223, they can roll along the moving direction of the side plate and the folding ears on the side plate. In addition, a mold width adjustment member 225 is arranged between the edge-supporting drive 223 and the box body mold 21, and the position of the edge-supporting drive 223 on the mold width adjustment member 225 can be adjusted to reduce the driving stroke of the edge-supporting drive 223, shorten the edge-supporting time, improve production efficiency, and reduce energy consumption.

[0051] See also Figure 4In some embodiments, the edge-supporting assembly 22 further includes an edge-supporting adjustment rod 224, which is slidably connected to the edge-supporting member 221, and the edge-supporting drive 223 is connected to the edge-supporting adjustment rod 224. The box body mold 21 is selected according to the size and dimensions of the folding box actually produced, so that the edge-supporting member 221 is connected to the edge-supporting adjustment rod 224, and can be adjusted according to the folding box actually produced. In addition, a edge-supporting track 226 is provided on the mold width adjustment member 225, and an edge-supporting slider 227 is slidably connected to the edge-supporting track 226, and the edge-supporting slider 227 is connected to the edge-supporting adjustment rod 224, so that the edge-supporting member 221 and the folding ear member 222 have a small movement resistance under the action of the edge-supporting drive 223. A locking member can be set between the edge-supporting adjustment rod 224 and the edge-supporting member 221 to prevent the position of the edge-supporting member 221 from changing again after adjustment, thereby affecting the edge-supporting operation.

Specifically, the first drive 232 is connected to the pressing stroke plate 233, and the pressing stroke plate 233 is provided with a pressing track 234, a synchronous belt 235 and two proximity switches 238. The first drive 232 drives the synchronous belt 235 to transmit, and the pressing member 231 is provided with a synchronous block 236 connected to the belt transmission and a pressing slider 237 slidably connected to the pressing track 234, so that the first drive 232 drives the pressing member 231 to move; the two proximity switches 238 are respectively arranged beside the two ends of the pressing track 234, and the pressing slider 237 is provided with a switch sensing element 239 corresponding to the proximity switch 238, so that when the proximity switch 238 and the switch sensing element 239 are close to each other, the movement of the pressing member 231 is stopped to prevent the pressing member 231 from sliding out of the pressing track 234 and causing impact and collision to the components connected to the pressing member 231 and causing damage.

The cover end of the leather shell enters first, and the feed positioning assembly 13 of the conveying mechanism 1 and the conveyor belt assembly 11 first fix the conveying position of the leather shell, which is convenient for subsequent operations and high production accuracy. When the box body part of the leather shell enters between the conveyor belt 111 and the feed guide wheel 135, the lifting member 141 lifts the side plate of the leather shell, and then the leather shell enters the position of the clamping member 15 and is supported and erected by it. After the leather shell is limited by the displacement limiter 181, the lower pressing member 231 drives the box body mold 21 to move downward and contact the leather shell, and then the edge support member 221 and the folding ear member 222 fit the leather shell, the side plate and the folding ears on the side plate to the box body mold 21. The vacuum suction cup 211 sucks the skin, side panels and folding ears on the side panels onto the box body mold 21. At this time, the edge support 221 and the folding ear 222 are reset, and then the conveyor frame 112 moves outward under the action of the position adjustment drive 122 to avoid hitting the downward moving box body mold 21 and the skin. When the skin reaches below it, the anti-warping pressure wheel 161 and the conveyor belt 111 have a stable transmission effect on the skin. After the conveyor frame 112 moves outward, the anti-warping pressure wheel 161 and the support guide wheel 171 have an anti-warping effect on the skin. Then the lower pressing member 231 drives the box body mold 21 to continue to move downward and reach the pressing station. The pressing member 31 presses the folding box under the action of the pressing drive 32, mainly pressing the bonding part of the folding ears. After that, the pressing member 31 is reset, the box body mold 21 and the top box member 41 bring the folding box back to the top of the conveyor belt 111, and the conveyor belt frame 112 returns to the position just supporting the folding box under the action of the position adjustment drive 122, and the box pusher 241 pushes the folding box from the box body mold 21 under the action of the box pusher drive 242, and drops it onto the conveyor belt 111. The anti-warping pressure wheel 161 rises under the action of the anti-warping pressure wheel drive 163, and the leather shell is conveyed out by the conveyor belt 111, and the assembly of the folding ears of the folding box is completed.

[0064] To summarize, the first driving component 23 of the present invention drives the box body mold 21 to connect with the skin shell transmitted by the conveying mechanism 1, and the two sets of edge support components 22 bend the side panels and close to the box body mold 21, so that the skin shell and the side panels are three-dimensionally formed, and then the first driving component 23 drives the pressing station, and the pressing drive 32 drives the two pressing parts 31 to press the folded ear bonding parts of the side panels, so that the folded ear bonding parts with glue are firmly bonded, and the folded ears are automatically bonded by machinery, thereby improving production efficiency and product precision, and reducing defective rate and production cost.
