Description

Technical Field

[0001] This utility model belongs to the technical field of printing and packaging equipment, and relates to a correction mechanism for a high-speed box gluing machine. Background Technology

[0002] In the packaging and printing industry, box gluing is the final step in packaging box processing. The process involves folding and gluing the printed, die-cut cardboard sheets. During gluing, machine vibrations or other external factors can cause the box sheets to shift or become skewed when fed into the pre-folding unit. This reduces the precision of subsequent processing steps, leading to defective products and ultimately losses. Therefore, to reduce or avoid this paper feeding skew, a correction mechanism is typically used to improve the accuracy of the gluing process, thereby improving product quality and processing efficiency.

[0003] Existing gluing machines are equipped with correction devices during the paper feeding process, mostly using the BOBST guide rail correction method. This involves using a tilting belt and pressure rollers to create an angle, thus correcting any skewed paper. A positioning guide bar on the other side maintains the corrected state until the paper is conveyed parallel to the bottom, completing the correction process. While these correction devices can correct misalignment or skew in the box sheets, ensuring processing accuracy, their complex designs limit their effectiveness. This makes them difficult to adjust flexibly during actual operation, thus failing to fully meet the demands of real-world production and thus having certain limitations. Utility Model Content

[0004] The purpose of this invention is to provide a correction mechanism for a high-speed box gluing machine, which solves the problem of inflexible correction in existing correction devices.

[0005] The technical solution adopted in this utility model is a correction mechanism for a high-speed box gluing machine, including opposing wall plates, which are fixed to form a frame by connecting rods; an adjusting screw is horizontally arranged on the frame, and a correction offset plate is fixedly connected to the adjusting screw, which is parallel to the wall plates; a motor and several first transmission guide wheels are fixed on one side of the correction offset plate, and a conveyor belt is wound around the output shaft of the motor and the first transmission guide wheels; a first fixing plate is fixed at the top of the correction offset plate, and a correction wheel assembly is movably connected to the first fixing plate, through which the conveyor belt forms a complete running trajectory; several second transmission guide wheels are fixedly connected to the first fixing plate, and the second transmission guide wheels and the correction wheel assembly are on the same horizontal plane, with a correction belt wound around the output shaft of the motor and the second transmission guide wheels, the part of the correction belt near the correction wheel assembly being vertical and parallel to the correction wheel assembly, and the plane of the conveyor belt in the correction wheel assembly always intersecting with the correction belt near the correction wheel assembly.

[0006] The features of this utility model also include:

[0007] The alignment wheel assembly includes a second fixed plate, which is movably connected to the first fixed plate via a rotating shaft. Several alignment pressure rollers are fixed on the second fixed plate. The alignment pressure rollers are horizontally and evenly arranged in two rows, with a gap between the two rows of alignment pressure rollers for the conveyor belt to pass through.

[0008] The second fixing plate has an L-shaped connecting plate at its end, with a horizontal waist-shaped hole on the L-shaped connecting plate. A corresponding retaining member is fixed on the first fixing plate, with a through hole on the retaining member. The first fixing plate and the second fixing plate are fixed by retaining the lever in the through hole and the waist-shaped hole.

[0009] The second fixing plate includes a first baffle and a second baffle on the same vertical plane. Several correction pressure rollers are fixed on the first baffle and the second baffle to form two rows. A spring is provided between the first baffle and the second baffle. A through hole extending to the second baffle is opened on the first baffle. A threaded hole is opened at the corresponding position on the second baffle. A locking bolt is provided on the through hole of the first baffle, and the locking bolt matches the threaded hole.

[0010] Two springs are provided on the first baffle and the second baffle. There are corresponding through holes on the first baffle, and two corresponding threaded holes and two locking bolts. A locking wrench is fixedly connected to the top of the locking bolt.

[0011] The offset correction plate has two horizontal through holes, and the wall panel also has corresponding openings. The adjusting screw passes through the through holes and the openings, and the nut on the adjusting screw is fixed to the offset correction plate. The two ends of the adjusting screw are fixed to the wall panel through the openings.

[0012] The second drive guide wheel adopts a combination of horizontal and vertical arrangement.

[0013] The conveyor belt and the guide belt are driven by the same motor.

[0014] The adjusting screw is fixedly connected to a handle.

[0015] The bottom of the wall panel is fixedly connected to a shock-absorbing and pressure-resistant support column.

[0016] The conveyor belt of the correction mechanism of this utility model is arranged and connected to the motor through the first transmission guide wheel for conveying box pieces; a row of adjustable angle correction pressure rollers are evenly arranged above the box pieces, and the transmitted box pieces are moved to one side by swinging the angle; the correction belt is connected to the motor through the second transmission guide wheel, so that the conveyor belt and the correction belt maintain the same speed.

[0017] The above-described setup allows for rapid adjustment of the correction roller angle, and the angle between the correction roller and the correction belt is easily adjustable, enabling adjustment of the direction in which the box sheet approaches the correction belt. This technical solution, through its correction belt, eliminates the need for traditional guide strip positioning, allowing for flexible adjustment. Its speed is consistent with the conveyor speed of the box sheet, ensuring effective correction during movement and preventing damage to the box sheet due to excessive speed or unsatisfactory correction results. Its rational structural design facilitates convenient paper correction adjustment, providing better correction effects and thus better meeting actual production needs. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 and Figure 2 As shown, the present invention discloses a correction mechanism for a high-speed box-gluing machine. This mechanism includes opposing wall plates 1, with a lead screw adjustment mechanism on the upper part of the wall plates 1, and a correction plate 4 fixed to the adjustment mechanism. The correction plate 4 is arranged side-by-side with the wall plates 1, forming a frame via connecting rods 2. A motor 5 and four first transmission guide wheels 6 are fixed to one side of the correction plate 4. Conveyor belts 7 are respectively installed on the output shafts of the first transmission guide wheels 6 and the motor 5.

[0023] A first fixed plate 8 is fixed to the top of the offset correction plate 4. The first fixed plate 8 is movably connected to the offset correction wheel set 9 via a rotating shaft. The conveyor belt 7 forms a motion trajectory through the offset correction wheel set 9. Several second transmission guide wheels 10 are installed on the first fixed plate 8. The second transmission guide wheels 10 and the offset correction wheel set 9 are on the same horizontal plane. These transmission guide wheels are respectively connected to the output shaft of the motor 5 by the offset correction belt 11.

[0024] The alignment roller assembly 9 is connected to the first fixed plate 8 via a second fixed plate 91, which is movably connected to the first fixed plate 8 via a rotating shaft. Several alignment rollers 92 are mounted on the second fixed plate 91, arranged horizontally in two rows, with a certain space between them and the conveyor belt 7. The distance between the two rows of alignment rollers 92 can be determined based on the total thickness of the conveyor belt 7 and the diaphragm.

[0025] The portion of the guiding belt 11 near the guiding wheel assembly 9 is vertical and parallel to the assembly 9, and the plane of the conveyor belt 7 intersects with the portion of the guiding belt 11 near the assembly 9. This arrangement ensures that regardless of the box's position on the conveyor belt 7, it remains within the obstruction of the guiding belt 11 and will not exceed its range. Furthermore, during the box's movement, its position is continuously corrected by the guiding belt 11, thus meeting the requirements of subsequent processes.

[0026] The first baffle 911 and the second baffle 912 are contained within the second fixed plate 91. They are arranged horizontally to form two additional rows of straightening pressure rollers 92. A spring 913 is located between the two baffles, and the first baffle 911 has a through hole that connects to a threaded hole on the second baffle 912. The through hole on the first baffle 911 is connected to the threaded hole by a locking bolt.

[0027] To ensure the effectiveness of the conveyor belt 7 and the guide belt 11, both the conveyor belt 7 and the guide belt 11 are tensioned by cylinders to maintain the same tension at all times.

[0028] The guiding belt 11 adopts a horizontal and vertical combination arrangement of the second transmission guide wheel 10. The guiding belt 11 and the conveyor belt 7 share the same power source, that is, the same motor 5 provides the driving force, so that the box pieces achieve the guiding effect during movement. The guiding belt 11 and the conveyor belt share the same motor 5, so that their belt linear speeds are the same.

[0029] In this embodiment, in order to ensure the convenience of each adjusting screw 3 and locking bolt, a locking wrench is fixedly connected to the top of the locking bolt, and a handle 12 is fixedly connected to the adjusting screw 3, which can realize quick operation and thus achieve the effect of rapid adjustment.

[0030] In addition, vibration is inevitable in the actual production process of high-speed box gluing machine. Long-term vibration will eventually affect the performance of the correction mechanism. Therefore, a shock-absorbing and pressure-resistant support column 13 is fixedly connected to the bottom of the wall panel 1, which can alleviate the adverse effects of vibration.

[0031] To further illustrate the effectiveness of this technical solution, the following application examples will be used to explain it in detail.

[0032] Application Example 1: The correction mechanism in a high-speed carton gluing machine is used in the production of pharmaceutical packaging boxes.

[0033] This technical solution can be used in high-speed packaging machines for pharmaceutical packaging. Wall panels 1 are connected by connecting rods 2 to form a frame. A correction plate 4 is installed on wall panels 1. The correction plate 4 drives the conveyor belt 7 via a motor 5 and a first transmission guide wheel 6, and simultaneously drives the correction belt 11 via a second transmission guide wheel 10. Together with the correction pressure roller 92 on the second fixed plate 91, it achieves horizontal and vertical adjustment of the conveyor belt 7 and the correction belt 11. When the pharmaceuticals move on the conveyor belt 7, the adjustment by the correction mechanism ensures stable machine operation, producing high-quality, high-efficiency pharmaceutical packaging.

[0034] Application Example 2: The correction mechanism in a high-speed carton gluing machine is applied in the food processing and packaging industry.

[0035] This technical solution can be used in box-gluing machines in the food processing and packaging industry. A correction plate 4 is installed on wall panel 1. A motor 5 and a first transmission guide wheel 6 drive the conveyor belt 7, while a second transmission guide wheel 10 drives the correction belt 11. Together with the correction pressure roller 92 on the second fixed plate 91, this ensures that both the conveyor and correction belts are horizontally and vertically adjusted. As food moves on the conveyor belt 7, the correction mechanism ensures high-quality, high-efficiency food packaging through adjustments.

[0036] This mechanism is designed for use in machines with similar feeding requirements. It features a correction and fine-tuning system, enabling better fulfillment of precision requirements for conveyed materials during long-distance transport. It exhibits high stability and reliability during operation and is very easy to implement. In large-scale production of carton gluing machines, it can significantly improve the mechanization level of the machine, contributing to increased manufacturing efficiency and product quality.

[0037] In summary, the alignment mechanism for a box-gluing machine of this invention, by adjusting the positions of the motor 5 and the transmission wheel, enables the box-gluing machine to perform more accurate, stable, and efficient positioning. Furthermore, the mechanism of this invention is extremely easy to install and maintain, and can almost completely replace the traditional blade-type positioning mechanism, significantly improving the mechanization level of the box-gluing machine.
