Description

Technical Field

[0001] This utility model relates to the field of paper box production machinery technology, and in particular to an automatic folding mechanism for a corner gluing machine for processing drawer boxes. Background Technology

[0002] With the rapid development of modern technology and the leapfrog progress of society, various high-tech products are constantly being introduced to meet the needs of work and life. All products are sold after being packaged in cardboard boxes. This serves two purposes: firstly, it protects the contents from damage, and secondly, attractive packaging boxes can entice consumers to purchase. Therefore, a large number of cardboard boxes are produced using cardboard box manufacturing machinery.

[0003] However, during the production process, such as... Figure 1 As shown, when cardboard Z is processed into a cardboard box on the corner gluing machine, if the cardboard box being processed has a large difference in length and thickness (like a drawer in furniture), the folded cardboard Z is pushed parallel to the B1 end by the pushing mechanism of the corner gluing machine, so that the bottom A of the folded cardboard Z is located on the lifting position of the work platform composed of four pillars. During processing, the side-standing mechanism on the lower right side of position A is raised, simultaneously raising B1 on the right side of position A and C on both sides of B1, perpendicular to the bottom A of the folded cardboard Z. The folding mechanism (composed of a longitudinal mechanism and a transverse mechanism, with the longitudinal mechanism set on the transverse mechanism) on the work platform on both sides of C moves the transverse mechanism to the side of the upright C away from A, and the longitudinal mechanism set on the transverse mechanism moves the transverse mechanism. Move towards the upright C, pushing the C on both sides of B1, so that the upright C folds along the fold seam between B1 and C (pre-pressed). Simultaneously, the pressure head above A of the folded cardboard Z moves downwards (the bottom area of ​​the pressure head is the same as the bottom area of ​​A of the folded cardboard Z), pressing A of the folded cardboard Z downwards within the lifting position between the four supports. A drives the folded B1, C, and unclamped B2 to fold and move downwards (the fold seam between A and B2 pre-pressed). The gluing mechanisms at the four corners below A of the folded cardboard Z fold B2, which is on the same plane as A, along the fold seam between them, and simultaneously glue the four sides B1, B2, and the two Cs together to form a topless cardboard box (see attached). Figure 2 As shown), it then falls onto the moving conveyor belt and is removed from the corner applicator;

[0004] From the folding process of the folded cardboard Z above, we can see that when folding C on both sides of B1, the folding mechanism located on the working platform on both sides of C needs to move longitudinally and laterally to fold C on both sides of B1. That is to say, two longitudinal cylinders and two lateral cylinders are needed to complete the above action. When processing drawer boxes, the processing space for the corner gluing machine is relatively small, which makes it very inconvenient for the operator to operate or maintain the machine. Summary of the Invention

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide an automatic folding mechanism for a simple-structured drawer box corner gluing machine.

[0006] An automatic folding mechanism for a drawer box corner gluing machine mainly consists of a machine base, a forming mechanism, and an adhesive mechanism. Four adhesive mechanisms are arranged diagonally on both sides below the machine base's worktable. The forming mechanism is located above and below the machine base's worktable. The machine base's worktable is divided into left and right sides, and each of the two left and right worktables is fixed with a paper guide frame. A paper guide slide is provided on the opposite side of the paper guide frame. The automatic folding mechanism is located between the two left and right worktables of the machine base. Through its rising and forward movement, the automatic folding mechanism causes the forming mold fixed at its front end to fold the cardboard Z, including B1 and C on both sides, into shape in one step.

[0007] The automatic folding mechanism consists of a lift drive plate, a connecting plate, a forward cylinder, and a folding mold. The lift drive plate is driven to move up and down by a drive cylinder below the worktable of one side of the machine. The connecting plate is connected to the top of the lift drive plate. A straight valve is fixedly connected to the end of the connecting plate facing the feeding end. The movable end of the straight valve is fixedly connected to a folding mold with its opening facing the feeding end.

[0008] The minimum dimension of the opening end of the folding mold is the maximum dimension of the bottom A of the folded cardboard Z;

[0009] The bottom of the two ends of the folding mold facing the feed end rises from low to high to the top of the folding mold;

[0010] The angle between the opening end of the folding mold and the two ends of the feeding end is greater than the angle of the opening end of the folding mold.

[0011] The connection between the folding mold and the movable end of the straight valve is a detachable fixed connection;

[0012] The width of the two paper guide slides provided opposite to each other on the paper guide frame is equal to the maximum width of C on both sides of the folded cardboard Z;

[0013] The forming mechanism consists of a drive motor fixed above the machine table, a forming head, and four support pillars below the machine table. The drive motor drives the forming head to move up and down, and the forming head 22 moves within the lifting position formed by the four support pillars.

[0014] This utility model eliminates the original folding mechanism without changing the original structure, and replaces it with a simple automatic folding mechanism. Through the combined action of rising, moving forward and folding mold, it can quickly process drawer boxes, and the operator can operate or maintain the machine in a simple and convenient manner.

[0021] See attached Figures 3-6 An automatic folding mechanism for a drawer box corner gluing machine mainly consists of a machine base 1, a forming mechanism 2, and an adhesive mechanism 3. Four adhesive mechanisms 3 are arranged diagonally on both sides below the worktable of the machine base 1. The forming mechanism 2 is located above and below the worktable of the machine base 1. The worktable of the machine base 1 is divided into left and right sides, and paper guide frames 11 are fixed on the two left and right worktables respectively. A paper guide slide 111 is provided on the opposite side of the paper guide frame 11. It also includes an automatic folding mechanism 4, which is located between the two left and right worktables of the machine base 1. The automatic folding mechanism 4 folds the cardboard Z at the front end of the forming mold by rising and moving forward, so that the B1 and C on both sides are folded in one step.

[0022] The automatic folding mechanism 4 consists of a lift drive plate 41, a connecting plate 42, a forward cylinder 43, and a folding mold 44. The lift drive plate 41 is driven to move up and down by a drive cylinder below the worktable of one side of the machine base 1. The connecting plate 42 is connected to the top of the lift drive plate 41. A straight valve 43 is fixedly connected to the end of the connecting plate 42 facing the feeding end. The movable end of the straight valve 43 is fixedly connected to the folding mold 44 with its opening facing the feeding end.

[0023] The minimum dimension of the opening end 441 of the folding mold 44 is the maximum dimension of the bottom A of the folded cardboard Z;

[0024] The bottom of the two ends 4411 of the folding mold 44 facing the feed end rises from low to high to the top of the folding mold 44.

[0025] The angle between the opening end of the folding mold 44 and the two ends 4411 of the feed end is greater than the angle of the opening end of the folding mold 44;

[0026] The connection between the folding mold 44 and the movable end of the straight valve 43 is a detachable fixed connection.

[0027] The width of the two paper guide rails 111 provided opposite to each other on the paper guide frame 11 is equal to the maximum width of C on both sides of the folded cardboard Z;

[0028] The forming mechanism 2 consists of a drive motor 21 fixed above the machine table, a forming head 22, and four support columns 23 below the machine table. The drive motor 21 drives the forming head 22 to move up and down, and the forming head 22 moves within the lifting position formed by the four support columns.

[0029] See attached Figures 1-6 When this utility model is applied, the cardboard Z to be folded is conveyed by a conveyor belt ( Figure 3(In the direction indicated by the arrow) the paper is conveyed. At this time, the C on both sides of the folded cardboard Z is transported across the two guide slides 111 of the guide frame 11. The automatic folding mechanism 4 is located below the worktable of the machine platform 1. When the bottom A of the folded cardboard Z reaches the lifting position formed by the four pillars 23 of the forming mechanism 2 located on the work platform, it stops moving. The vertical drive plate 41 is driven to move upward by the drive cylinder below the worktable of one side of the machine platform 1. At the same time, the rising folding mold 44 gradually lifts the B1 on the right side of position A and the C on both sides of B1. Meanwhile, the forming pressure head 22 is driven by the drive motor 21 to press down on the bottom A of the folded cardboard Z. The B1 on the right side of position A and the C on both sides of B1 are folded along the fold seam between A and B1. At the same time, the connecting plate 42 is connected to the straight valve 43 at the top of the vertical drive plate 41 facing the feeding end, which drives the folding mold 44 to move forward. Since the minimum size of the opening end 441 of the folding mold 44 is the folded cardboard Z The bottom A is the largest dimension, and the open end 441 abuts against the C on both sides of the A position. Since the bottom of the two ends 4411 of the open end 441 facing the feed end rises from low to high to the top of the folding mold 44, C is gradually folded along the fold seam between C and B1. Similarly, the forming head 22 continues to move down under the drive of the drive motor 21, and the bottom A of the folded cardboard Z is pressed into the four pillars 23 of the forming mechanism 2 and moves down along the space between the four pillars 23. At this time, the undone B2 is also supported by the two pillars 23 perpendicular to the moving path of the folded cardboard Z and is folded along the fold seam between A and B2. Thus, the folded cardboard Z forms a drawer box with A as the bottom and B1, B2 and two C as the four walls. As the drawer box continues to move down, the four gluing mechanisms 3 (existing technology) located diagonally arranged on both sides below the worktable of the machine 1 glu the four fold seams that have been folded. The glued drawer box falls into the moving conveyor belt below and is removed.

[0030] When the angle between the opening end of the folding mold 44 and the two ends 4411 of the feeding end is greater than the angle of the opening end of the folding mold 44, if the folded cardboard Z is not placed correctly or is not cut properly during the movement, the two ends 4411 that are greater than the angle of the opening end of the folding mold 44 can automatically correct the position of the folded cardboard Z on the lifting position formed by the four pillars 23 of the forming mechanism 2 entering the working platform, thus ensuring the yield rate in the production of drawer boxes.
