Description

Technical Field

[0001] This utility model belongs to the field of box gluing machine technology, and in particular relates to a nailing mechanism for an intelligent box gluing machine. Background Technology

[0002] The carton gluing machine is the final step in the carton production process. It is mainly used for gluing corrugated cardboard to meet the production requirements of various products and adapt to the packaging needs of a variety of products. It is a relatively ideal carton equipment.

[0003] Traditional manual box gluing can no longer meet current market demands because it requires substantial labor costs, takes a long time, and cannot guarantee product quality. Therefore, there is an urgent need for a fully automatic box gluing machine to replace manual production, offering advantages such as high efficiency, ease of operation, and superior performance.

[0004] Currently, a typical box gluing machine includes a paper feeding mechanism, a correction mechanism, a folding and gluing mechanism, and an output mechanism. In use, the paper feeding mechanism and the correction mechanism transport two pieces of corrugated cardboard to the folding device, then apply adhesive to the folded edges of the corrugated cardboard, and then glue the corresponding folded edges of the two pieces of corrugated cardboard together on the box gluing mechanism to complete the box gluing operation.

[0005] However, existing box gluing machines have at least the following drawbacks: because the adhesive is only applied to the corresponding folded edges of the corrugated cardboard, the strength is not high, resulting in the glued boxes not being able to hold heavy objects, thus limiting the scope of use of the boxes.

[0006] In view of this, the present invention aims to provide a nailing mechanism for an intelligent box gluing machine. The nailing mechanism is added between the folding and gluing mechanism and the output mechanism. The nailing operation is performed on the already glued folding edge, which greatly improves the bonding force between the two pieces of corrugated paper combined together, thereby increasing the load-bearing capacity of the box and expanding the applicable range of the box. Utility Model Content

The mounting plate is connected to the upper belt assembly or the lower belt assembly.

[0016] As an improvement to the nailing mechanism of the intelligent box gluing machine of this utility model, the bottom mold mechanism is disposed on one side of the lower belt assembly.

[0017] As an improvement of the nailing mechanism of the intelligent box gluing machine of this utility model, the bottom mold structure includes a steel sheet running between the folded edge and the paper body, a cam connected to the steel sheet, and a second motor for driving the cam to rotate. A nail forming mold is provided at the end of the steel sheet away from the cam. The nail forming mold is provided with two arc-shaped grooves. The nail head is provided above or below the steel sheet.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0037] like Figures 1 to 10 As shown, this utility model provides a nailing mechanism for an intelligent gluing machine, comprising:

[0038] Belt conveyor 1 for conveying folded cardboard; the front station of this utility model - the folding and gluing mechanism has folded and glued the cardboard. During the conveying process, the folded side of one cardboard is transported together with the unfolded side of another cardboard. At this time, the upper surface of the folded side of one cardboard is bonded to the lower surface of the unfolded side of the other cardboard.

[0039] A bottom mold mechanism 2 is used to separate the folded edge of a cardboard from the cardboard body and to form a nail; the bottom mold mechanism 2 can both prevent the folded edge of a cardboard from being nailed to its body and provide a mold for nailing the folded edge of a cardboard to the unfolded side of another cardboard.

[0040] And a staple head 3 for fastening the folded edge of one piece of cardboard to the body of another piece of cardboard. The main function of the staple head 3 is to provide a staple (similar to a book staple) and fasten it to the cardboard. This utility model does not limit the structure of the staple head 3; a conventional structure in the art can be used. A staple head such as that described in ZL202222393498.5 can be used, as long as it can provide a staple-like staple and fasten the folded edge of one piece of cardboard to the unfolded edge of another piece of cardboard.

[0041] The belt conveyor mechanism 1 includes a first motor 11, a drive pulley 12, a transmission belt 13, a first driven pulley 14, a second driven pulley 15, an upper belt assembly 16, and a lower belt assembly 17. The upper belt assembly 16 includes an upper belt 161, and the lower belt assembly 17 includes a lower belt 171. The drive pulley 12 is connected to the output shaft of the motor 11. The first driven pulley 14 and the second driven pulley 15 are connected to the drive pulley 12 via the transmission belt 13. The first driven pulley 14 is connected to the upper belt 161 via a first drive shaft 18, and the second driven pulley 15 is connected to the lower belt 171 via a second drive shaft 19. A gap is formed between the upper belt 161 and the lower belt 171, allowing two cardboard bodies to pass through. The motor 11 drives the drive pulley 12 to rotate, which in turn drives the first driven pulley 14 and the second driven pulley 15 to rotate together via the transmission belt 13. Finally, the first drive shaft 18 and the second drive shaft 19 drive the upper belt 161 and the lower belt 171 to rotate, thus moving the two cardboard bodies forward together.

[0042] The upper belt assembly 16 further includes a first roller 162 and a plurality of first guide rollers 163. The first roller 162 is connected to the first drive shaft 18, and the upper belt 161 is guided to rotate through the first roller 162 and the first guide rollers 163. The lower belt assembly 17 further includes a second roller 172 and a plurality of second guide rollers 173. The second roller 172 is connected to the second drive shaft 19, and the lower belt 171 is guided to rotate through the second roller 162 and the second guide rollers 163.

[0043] The integrated machine also includes a distance adjustment device 4, which includes a transmission power source 41, several tensioning pulleys 42, a transmission belt 43, a mounting plate 44, and several lead screws 45. The transmission power source 41 is connected to the tensioning pulleys 42, the several tensioning pulleys 42 are connected through the transmission belt 43, the end of the lead screw 45 is connected to the tensioning pulleys 42, and the lead screw 45 passes through the mounting plate 44. The mounting plate 44 is connected to the upper belt assembly 16 or the lower belt assembly 17.

[0044] The bottom mold mechanism 2 is located on one side of the lower belt assembly 17. In this invention, both the bottom mold mechanism 2 and the nail head 3 are provided in pairs for nailing the two sides of the cardboard. One nail head 3 is above the bottom mold mechanism 2, and the other is below the bottom mold mechanism 2.

[0045] The bottom mold mechanism 2 includes a steel sheet 21 running between the folded edge and the paper body, a cam 22 connected to the steel sheet 21, and a second motor 23 for driving the cam 22 to rotate. A nail forming mold 24 is provided at the end of the steel sheet 21 away from the cam 22.

[0046] The second motor 23 drives the cam 22 to rotate, and the cam 22 then drives the steel sheet 21 to move, which makes the movement of the steel sheet 21 more stable and provides support for the nailing operation of the cardboard.

[0047] The nail forming mold 24 has two arc-shaped grooves 241, which allow the nail to be formed according to the arc (similar to a stapler).

[0048] The steel sheet 21 is connected to the adapter block 26 via a long strip connecting piece 25, and the adapter block 26 is connected to the cam 22 via a transmission rod 27. Therefore, when the second motor 23 drives the cam 22 to rotate, the cam 22 drives the adapter block 26 to move together via the transmission rod 27, which in turn drives the long strip connecting piece 25 and the steel sheet 21 to move. Since at least two nails need to be driven into the cardboard, the position of the steel sheet 21 needs to be moved to perform nailing operations at different locations on different cardboard pieces.

[0049] The adapter block 26 includes a first adapter block 261 and a second adapter block 262. Both the first and second adapter blocks are L-shaped. One end of the first adapter block 261 is connected to the end of the elongated connecting piece 25 away from the steel sheet 21, and the other end of the first adapter block 261 is connected to the second adapter block 262. The transmission rod 27 is connected to the second adapter block 262. The second adapter block 262 is connected to the slider 28, which is slidably mounted on the slide rail 29. The slide rail 29 is connected to the fixing plate 210 of the motor 23 via a connecting plate 211. The motor 23 drives the cam 22 to rotate, which is converted into linear motion through the transmission rod 27. The transmission rod 27 drives the second adapter block 262 and the slider 28 to move left and right on the slide rail 29, thereby causing the steel sheet 21 to move back and forth.

[0050] A guide structure 212 is provided on the elongated connecting piece 25. The guide structure 212 includes a fixing block 2121 connected to the elongated connecting piece 25, a guide post 2122 disposed on the fixing block 2121, and a linear bearing 2123 disposed on the guide post 2122. The linear bearing 2123 provides linear guidance, enabling the guide post 2122 to move along the length of the elongated connecting piece 25. The linear bearing 2123 is disposed inside one end of the connecting plate 2124, and the other end of the connecting plate 2124 is connected to the post 2125. Two guide structures 212 are provided, and the posts of the two guide structures 212 are connected by a connecting post 213. The guide structure 212 is provided to improve the smoothness of the movement of the elongated connecting piece 25, thereby improving the smoothness of the running of the steel sheet 21.

[0051] Since at least two nails are typically needed to hammer into the cardboard, there are three ways to perform the hammering operation:

[0052] One method involves the upper belt 161 and lower belt 171 moving the cardboard, while the bottom mold structure 2 and the nail head 3 also move simultaneously. The steel sheet 21 runs between the folded edge and the cardboard body, and the nail head 3 provides the nail and presses it towards the folded edge of the cardboard. The nail penetrates the body of one cardboard piece and the folded edge of another, then contacts the nail forming mold 24 and is shaped according to its curvature, completing the nailing operation. After one nail is driven in, the cardboard is moved forward, and the nail head 3 drives in the next nail.

[0053] Another method involves keeping the upper belt 161 and lower belt 171 stationary: the bottom mold structure 2 and the nail head 3 move together; the steel plate 21 runs between the folded edge and the cardboard body; the nail head 3 provides the nail and presses it towards the folded edge of the cardboard; the nail penetrates the body of one cardboard piece and the folded edge of another cardboard piece; then the nail contacts the nail forming mold 24 and is shaped according to its curvature, completing the nailing operation. After nailing one nail, the bottom mold structure 2 and the nail head 3 move together to another position on the folded edge of the cardboard, and then nail the next nail.

[0054] Another method involves the upper belt 161 and lower belt 171 moving: the bottom mold structure 2 and the nail head 3 remain stationary. The steel sheet 21 runs between the folded edge and the cardboard body. The nail head 3 provides the nail and presses it towards the folded edge of the cardboard. The nail penetrates the body of one cardboard piece and the folded edge of another. Then, the nail contacts the nail forming mold 24 and is shaped according to its curvature, completing the nailing operation. After one nail is driven in, the cardboard is moved forward, and the nail head 3 drives in the next nail.

[0055] This utility model also provides an intelligent gluing machine, including a control system and the following mechanisms controlled by the control system and arranged in sequence: a paper feeding mechanism 5, a correction mechanism 6, a folding and gluing mechanism 7, and an output mechanism 8. The folding and gluing mechanism 7 and the output mechanism 8 are connected by an integrated gluing and nailing machine 9 of this utility model. This utility model does not limit the paper feeding mechanism 5, the correction mechanism 6, the folding and gluing mechanism 7, and the output mechanism 8; conventional structures in the field can be used. The mechanisms in ZL202320293599.7 (An Intelligent Double-Layer Gluing Machine) can be used. In that patent, the upper and lower paper feeding mechanisms are equivalent to the paper feeding mechanism 5 in this application; the upper and lower correction mechanisms are equivalent to the correction mechanism in this application; the upper and lower forming mechanisms are equivalent to the folding and gluing mechanism 7 in this application; and the pressing mechanism is equivalent to the output mechanism in this application.

[0056] This invention adds a nailing mechanism 9 between the folding and gluing mechanism 7 and the output mechanism 8, and performs nailing operations on the already glued folded edge, which greatly improves the bonding force between the two pieces of corrugated paper combined together, thereby increasing the load-bearing capacity of the box and broadening the scope of application of the box.

[0057] The bottom mold structure 2, driven by the second motor 23 and cam 22, runs between the folded edge and the corrugated paper body. It provides rigid support for the staples (similar to large staples) and isolates the folded edge from the corrugated paper body. The use of the second motor 23 and cam 2 makes the bottom mold run more smoothly. In use, two folded corrugated papers are transported to the stapler mechanism as follows: the folded edge of one corrugated paper is opposite the uncfolded edge of the other corrugated paper, and they are transported together to the stapler mechanism by a belt. The bottom mold is located between the folded edge and the corrugated paper body, separating the folded edge from the corrugated paper body. The staple head in the stapler mechanism drives the staples up / down, nailing the folded edge of one corrugated paper to the body of the other corrugated paper together, improving the connection strength between the two.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model.
