Description

Technical Field

[0001] The present invention belongs to the technical field of folder gluers, and in particular relates to an intelligent folder gluer. Background Art

[0002] The folder gluer is the last process equipment in carton production. It is mainly used for gluing corrugated cardboard to meet the production requirements of multiple varieties and adapt to the packaging needs of various products. It is an ideal carton equipment.

[0003] Traditional manual folder gluing can no longer keep up with current market demand, as it requires huge labor costs, takes a long time to produce, and cannot guarantee product quality. Therefore, there is an urgent need for a fully automatic folder gluing machine to replace manual production, with advantages such as high efficiency, easy operation, and good performance.

[0004] At present, the box gluing machine generally includes a paper feeding mechanism, a correction mechanism, a folding and gluing mechanism and an output mechanism. When in use, the two pieces of corrugated cardboard are transported to the folding device through the paper feeding mechanism and the correction mechanism, and then glue is applied on the folded edges of the corrugated cardboard. Then, the corresponding folded edges of the two pieces of corrugated cardboard are glued together on the box gluing mechanism to complete the box gluing operation.

[0005] However, the existing box gluing machines have at least the following disadvantages: since the glue is only applied to the corresponding folded edges of the corrugated cardboard, the firmness is not high, resulting in that the glued boxes cannot be used to hold heavy objects, which limits the scope of use of the boxes.

[0006] In view of this, the present invention aims to provide an intelligent box gluing machine, which adds a stapling mechanism between the folding edge gluing mechanism and the output mechanism, and performs a stapling operation on the glued folding edge, thereby greatly improving the bonding force between the two pieces of corrugated paper combined together, thereby improving the load-bearing capacity of the box and broadening the scope of application of the box. Summary of the Invention

[0038] like Figures 1 to 10 As shown, the present invention provides a stapling mechanism of an intelligent folder gluer, including a control system and the following mechanisms controlled by the control system:

[0039] A belt conveyor mechanism 1 is used to transport folded cardboards; the folding and gluing mechanism, which is a preceding station of the present invention, has already folded and glued the cardboards. During transportation, 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.

[0040] 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 prevent the folded edge of a cardboard from being nailed together with its body, and can also provide a mold for nailing the folded edge of a cardboard to the unfolded side of another cardboard.

[0041] and a nail head 3 for nailing the folded edge of one cardboard to the main body of another cardboard. The main function of the nail head 3 is to provide a nail (similar to a staple) and nail it to the cardboard. The present invention does not limit the structure of the nail head 3. A conventional structure in the art can be used. A nail head such as that described in ZL202222393498.5 can be used as long as it can provide a nail similar to a staple and nail the folded edge of one cardboard to the unfolded side of another cardboard.

[0042] The belt conveyor mechanism 1 includes a first motor 11, a driving 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 driving pulley 12 is connected to the output shaft of the motor 11. The first and second driven pulleys 14, 15 are connected to the driving pulley 12 via the transmission belt 13. The first driven pulley 14 is connected to the upper belt 161 via a first driving shaft 18, and the second driven pulley 15 is connected to the lower belt 171 via a second driving shaft 19. A gap is formed between the upper and lower belts 161, 171, allowing two cardboard bodies to pass through. The driving pulley 12 is driven by the motor 11, which in turn drives the first and second driven pulleys 14, 15 to rotate together via the transmission belt 13. Finally, the upper and lower belts 161, 171, are driven by the first and second driving shafts 18, 19, respectively, thereby carrying the two cardboard bodies forward.

[0043] The upper belt group 16 also includes a first roller 162 and several first guide wheels 163. The first roller 162 is connected to the first driving shaft 18, and the upper belt 161 is guided and rotated by the first roller 162 and the first guide wheel 163; the lower belt group 17 also includes a second roller 172 and several second guide wheels 173. The second roller 172 is connected to the second driving shaft 19, and the lower belt 171 is guided and rotated by the second roller 162 and the second guide wheel 163.

[0044] The all-in-one 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 screw rods 45. The transmission power source 41 is connected to the tensioning pulley 42, and the several tensioning pulleys 42 are connected through the transmission belt 43. The end of the screw rod 45 is connected to the tensioning pulley 42, and the screw rod 45 passes through the mounting plate 44, and the mounting plate 44 is connected to the upper belt group 16 or the lower belt group 17.

[0045] The bottom mold mechanism 2 is arranged on one side of the lower belt group 17. In the present invention, the bottom mold mechanism 2 and the nail head 3 are both provided in two, for nailing the two sides of the cardboard, wherein one nail head 3 is above the bottom mold mechanism 2 and the other is below the bottom mold mechanism 2.

[0046] 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 one end of the steel sheet 21 away from the cam 22.

[0047] The second motor 23 drives the cam 22 to rotate, and the cam 22 drives the steel sheet 21 to move, so that the movement of the steel sheet 21 can be more stable, providing support for the nailing operation of the cardboard.

[0048] The nail forming die 24 is provided with two arc-shaped grooves 241 so that the nail can be formed according to this arc (similar to a stapler).

[0049] The steel sheet 21 is connected to the adapter block 26 via a long 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 via the transmission rod 27, which in turn drives the long connecting piece 25 and the steel sheet 21. Because at least two nails need to be driven into each cardboard sheet, the steel sheet 21 needs to be moved to allow for nailing at different locations on different cardboard sheets.

[0050] The adapter block 26 includes a first adapter block 261 and a second adapter block 262. Both the first adapter block 261 and the second adapter block 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 fixed 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 by 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 driving the steel sheet 21 to move back and forth left and right.

[0051] A guide structure 212 is provided on the long strip connecting piece 25. The guide structure 212 includes a fixed block 2121 connected to the long strip connecting piece 25, a guide column 2122 provided on the fixed block 2121, and a linear bearing 2123 provided on the guide column 2122. The linear bearing 2123 realizes linear guidance to realize the movement of the guide column 2122 in the length direction of the long strip connecting piece 25. The linear bearing 2123 is provided in one end of the connecting plate 2124, and the other end of the connecting plate 2124 is connected to the column 2125. There are two guide structures 212, and the columns of the two guide structures 212 are connected by a connecting column 213. The setting of the guide structure 212 is to improve the smoothness of the movement of the long strip connecting piece 25, thereby improving the smoothness of the operation of the steel sheet 21.

[0052] Since it is generally necessary to nail at least two nails on the cardboard, there are three ways to implement the nailing operation:

[0053] In one method, the upper belt 161 and the lower belt 171 move the cardboard, while the bottom mold structure 2 and the nail head 3 also move together: the steel sheet 21 runs between the folded edge and the main body of the cardboard, and the nail head 3 provides the nail and presses it toward the folded edge of the cardboard. The nail penetrates the main body of one cardboard and the folded edge of the other cardboard. The nail then contacts the nail forming mold 24 and is formed according to the curvature on it, completing the nailing operation. After one nail is nailed, the cardboard is moved forward, and the nail head 3 drives the next nail.

[0054] Another method involves keeping upper and lower belts 161 and 171 stationary. The bottom mold structure 2 and nail head 3 move together, allowing the steel sheet 21 to run between the folded edge and the main body of the cardboard. The nail head 3 provides the nail and presses it toward the folded edge of the cardboard. The nail penetrates the main body of one cardboard and the folded edge of the other cardboard. The nail then contacts the nail forming mold 24 and is formed according to the curvature of the mold, completing the nailing operation. After one nail is driven in, the bottom mold structure 2 and nail head 3 move together to another position on the cardboard folded edge, allowing the next nail to be driven in.

[0055] Another method involves moving the upper and lower belts 161 and 171. Neither the bottom mold structure 2 nor the nail head 3 moves. The steel sheet 21 runs between the folded edge and the main body of the cardboard. The nail head 3 provides the nail and presses it toward the folded edge of the cardboard. The nail penetrates the main body of one cardboard and the folded edge of the other cardboard. The nail then contacts the nail forming mold 24 and is formed according to the curvature of the mold, completing the nailing operation. After one nail is nailed, the cardboard is moved forward, and the nail head 3 drives the next nail.

[0056] The present invention also provides an intelligent folder gluing machine, comprising a paper feeding mechanism 5, a correction mechanism 6, a folding and gluing mechanism 7 and an output mechanism 8, which are controlled by a control system and arranged in sequence, and a nailing mechanism 9 of the present invention is arranged between the folding and gluing mechanism 7 and the output mechanism 8. The present invention does not limit the paper feeding mechanism 5, the correction mechanism 6, the folding and gluing mechanism 7 and the output mechanism 8, and conventional structures in the field can be used. The mechanism in ZL202320293599.7 (an intelligent double-stitching folder gluing machine) can be used, wherein the upper paper feeding mechanism and the lower paper feeding mechanism in the patent are equivalent to the paper feeding mechanism 5 in the present application, the upper deviation correction mechanism and the lower deviation correction mechanism are equivalent to the correction mechanism in the present application, the upper forming mechanism and the lower forming mechanism are equivalent to the folding and gluing mechanism 7 in the present application, and the pressing mechanism therein is equivalent to the output mechanism in the present application.

[0057] The present invention adds a nailing mechanism 9 between the folding edge gluing mechanism 7 and the output mechanism 8, and performs a nailing operation on the glued folding edge, thereby greatly improving the bonding force between the two pieces of corrugated paper combined together, thereby improving the load-bearing capacity of the box and broadening the application range of the box.

[0058] The bottom mold structure 2 is driven by a second motor 23 and a cam 22 to run between the folded edge and the main body of the corrugated paper. It not only provides a hard surface support for the nails (similar to large staples), but also isolates the folded edge from the main body of the corrugated paper. The use of the second motor 23 and the cam 2 makes the bottom mold run more smoothly. During use, two folded corrugated papers are run into the nailing mechanism in the following manner: the folded edge of one corrugated paper is opposite the folded edge of the other corrugated paper, and they are transported to the nailing mechanism together via a belt. The bottom mold is located between the folded edge and the main body of the corrugated paper, separating the folded edge from the main body of the corrugated paper. The nail heads in the nailing mechanism nail upwards / downwards, nailing the folded edge of one corrugated paper to the main body of the other corrugated paper, improving the firmness of the connection between the two.
