Description

Technical Field

[0001] This utility model relates to the field of box gluing machines, specifically to a Braille imprinting mechanism for box gluing machines. Background Technology

[0002] In the packaging and printing industry, carton gluing machines are used for cardboard box processing and have been given more functional requirements in recent years. Among them, the introduction of Braille embossing mechanisms enables the pressing of tactile Braille markings on the surface of cardboard boxes, meeting the needs of visually impaired people for barrier-free access to product information and reflecting an important trend in socially inclusive design.

[0003] Braille embossing in a carton gluing machine includes a punch roller and a die roller. Typically, the die roller is a general-purpose roller at the bottom, with grooves on its surface. The punch roller is on top, its surface covered by a convex template. This convex template has Braille protrusions. The carton is pressed by the punch roller and the die roller, forming readable Braille on its surface. Different cartons require different Braille content, necessitating the replacement of the convex template on the punch roller. The convex template covers the punch roller, which has a crossbeam above it, a die roller below it, and mounting plates on the left and right sides. The installation position of the punch roller is highly limited, and replacing the convex template is difficult and inefficient. Utility Model Content

[0004] In view of the technical problems existing in the background art, the technical problem solved by this utility model is to provide a Braille embossing quick-release device for a box gluing machine, which facilitates the replacement of the convex template and improves the replacement efficiency.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: The Braille embossing quick-assembly device for a box-gluing machine is characterized by comprising a base, a punch roller, a punch template, and a pressure roller.

[0006] The punch roller is mounted on a drive shaft, which is rotatably mounted on a machine base and connected to a motor. The motor is mounted on the machine base. The surface of the punch roller is provided with a mounting groove, and a limiting protrusion is provided in the mounting groove. The limiting protrusion is equipped with a locking element, and the top of the limiting protrusion is not higher than the surface of the punch roller.

[0007] The convex template has through holes at both ends corresponding to the limiting protrusions;

[0008] The pressure roller is rotatably mounted on a rotating shaft, which is rotatably mounted on a swing arm. The swing arm is oscillatingly mounted on a crossbeam, which is mounted on a machine base. The swing arm causes the pressure roller to press or separate from the punch roller.

[0009] When replacing the punch template, the drive shaft rotates to rotate the mounting groove of the punch roller to an angle convenient for the operator to replace it. The locking device is removed, and the punch template is removed from the punch roller. Then, one end of the new punch template is placed on the limiting protrusion. Next, the swing arm swings, and the pressure roller presses against the punch roller and holds the punch template in place. The motor drives the drive shaft to rotate, which in turn drives the punch roller to rotate. The pressure roller always presses against the surface of the punch roller, so that the punch template covers the surface of the punch roller. After the punch roller rotates one revolution, the through hole at the other end of the punch template aligns with the limiting protrusion. The other end of the punch template is then placed on the limiting protrusion and locked with the locking device. This replacement is convenient and quick.

[0010] Preferably, at least two limiting protrusions are provided, and the locking element is a nut, with the limiting protrusions and the nut being threadedly connected. Threaded connection is convenient and secure to install.

[0011] Preferably, the mounting groove is arc-shaped, and the connection between the mounting groove and the surface of the punch roller is also arc-shaped. This avoids scratching the printed cardboard.

[0012] Preferably, the swing arm is connected to a self-locking linkage mechanism, which includes a first link, a second link, and a third link. The first link is rotatably mounted on the mounting base and is also rotatably connected to the upper end of the second link. The third link is rotatably connected to both the mounting base and the lower end of the second link. The swing arm is connected to the third link.

[0013] When the pressure roller and the punch roller are pressed together, the second connecting rod is pressed together with the mounting base. The first hinge point of the first connecting rod and the second connecting rod is above the second hinge point of the first connecting rod and the mounting base, and the included angle between the first connecting rod and the second connecting rod is not greater than 90 degrees. The first connecting rod swings relative to the mounting base, which drives the second connecting rod to move, causing the third connecting rod to swing relative to the mounting base. The third connecting rod then drives the swing arm to swing, causing the pressure roller to press against or away from the punch roller. When the pressure roller and the punch roller are pressed together, the first connecting rod and the second connecting rod are in a self-locking state, keeping the pressure roller and the punch roller pressed together. The self-locking is released only when the angle between the first connecting rod and the second connecting rod is greater than 90 degrees under the action of external force.

[0014] Preferably, the mounting base is provided with a slide groove for the second link to slide. The slide groove serves as a guide and limiter, stabilizing the swing of the second link. The first link is connected to a handle for easy manual operation by the operator.

[0015] Preferably, the crossbeam is provided with a first guide rail and a second guide rail;

[0016] The drive shaft is a splined shaft, the punch roller is sleeved on the outside of the splined shaft and splinedly connected to the splined shaft, and the punch roller is rotatably mounted on the movable seat, and the movable seat is slidably mounted on the first guide rail;

[0017] The mounting base is slidably mounted on the second guide rail. The pressure roller is adjusted accordingly by changing the lateral position of the punch roller based on the Braille imprinting position or the spatial position.

[0018] Preferably, a screw is rotatably mounted on the base, the screw being parallel to the first guide rail, and the movable seat is threadedly connected to the screw. Rotation of the screw causes the movable seat to move laterally along the first guide rail, thus adjusting its lateral position. Attached Figure Description

[0025] The following description, in conjunction with the accompanying drawings, details the embodiments and working principles of this utility model. Figure 1 In the diagram, the X-axis is horizontal, representing the left-right direction; the Y-axis is vertical, representing the front-back direction; and the Z-axis is vertical, representing the up-down direction.

[0026] The Braille embossing quick-assembly device of this type of box gluing machine includes a base 6, a punch roller 1, a punch template, and a pressure roller 2. The punch roller 1 is mounted on a drive shaft 4, which is rotatably mounted on the base 6 and connected to a motor. The motor is mounted on the base 6 and drives the drive shaft 4 to rotate, which in turn drives the punch roller 1 to rotate. The surface of the punch roller 1 is provided with a mounting groove 19, and a limiting protrusion 20 is provided within the mounting groove 19. The limiting protrusion 20 is equipped with a locking element, and the top of the limiting protrusion 20 does not exceed the surface of the punch roller 1. The mounting groove 19 is arc-shaped, and the connection between the mounting groove 19 and the surface of the punch roller 1 is also arc-shaped to avoid scratching the embossed cardboard. The convex template has through holes at both ends corresponding to the limiting protrusions 20. The convex template covers the outside of the punch roller 1, and both ends of the convex template are sequentially fitted onto the limiting protrusions 20 through the through holes. The limiting protrusions 20 are then locked with the locking components, thus locking the convex template onto the punch roller 1. To facilitate locking, at least two limiting protrusions are provided, and the locking components are nuts. The limiting protrusions and nuts are threadedly connected, and the threaded connection is convenient and secure for installation.

[0027] The pressure roller 2 is rotatably mounted on a rotating shaft, which is rotatably mounted on a swing arm 8. The swing arm 8 is oscillatingly mounted on a crossbeam 7, which is mounted on a machine base 6. The swing arm 8 causes the pressure roller 2 to press against or separate from the punch roller 1. When replacing the punch template, the pressure roller 2 moves away from the punch roller 1, and the motor drives the drive shaft 4 to rotate, causing the mounting groove 19 of the punch roller 1 to rotate to an angle convenient for the operator to replace. The nut is then removed from the limiting protrusion, and the punch template is removed from the punch roller 1. Then, the beginning end of the new punch template is fitted onto the limiting protrusion 20, i.e., the limiting protrusion 20 passes through the through hole at the beginning end. Next, the swing arm 8 swings towards the punch roller 1, causing the pressure roller 2 to press against the punch roller 1 and hold the punch template in place. The motor drives the drive shaft... 4. Rotate the roller 8, causing the punch roller 1 to rotate, while the pressure roller 2 remains pressed against the surface of the punch roller 1. As the punch roller 1 rotates, the punch template smoothly covers the surface of the punch roller 1. After one revolution of the punch roller 1, the through hole at the tail end of the punch template aligns with the limiting protrusion 20. The tail end of the punch template is then fitted onto the limiting protrusion 20, at which point the tail end of the punch template covers the beginning end. The nut is threadedly connected to the limiting protrusion, locking the punch template onto the punch roller 1. This completes the replacement of the punch template, which is very convenient and quick. Because the pressure roller 2 presses against the punch template, the punch template remains in contact with the punch roller 1, making it easy for the operator to fit the tail end of the punch template onto the limiting protrusion 20 and tighten the nut. Finally, the swing arm 8 swings in the opposite direction, and the pressure roller 2 moves away from the punch roller 1, allowing the punch roller 1 to operate normally.

[0028] The swing arm 8 can be driven by a cylinder or a motor. In the attached diagram, the swing arm 8 is connected to a self-locking linkage mechanism 9. Without external force, the self-locking linkage mechanism 9 keeps the pressure roller 2 and the punch roller 1 pressed together. The self-locking linkage mechanism 9 includes a first link 13, a second link 16, and a third link 18. The first link 13 is rotatably mounted on the mounting base 15, and their rotatable connection point is hinge point A. The first link 13 is also rotatably connected to the upper end of the second link 16, and their rotatable connection point is the first hinge point 14. The third link 18 is rotatably connected to both the mounting base 15 and the lower end of the second link 16. The rotatable connection point between the third link 18 and the mounting base 15 is hinge point B, and the rotatable connection point between the third link 18 and the second link 16 is the second hinge point 17. The swing arm 8 is connected to the third link 18. To facilitate manual operation, the first connecting rod 13 is connected to a handle 10, which drives the first connecting rod 13 to rotate around hinge point A. The mounting base 15 is provided with a sliding groove for the second connecting rod 16 to slide. The sliding groove serves as a guide and limiter, ensuring stable swing of the second connecting rod 16. When the handle 10 is pressed down, the first connecting rod 13 swings clockwise around hinge point A. The second connecting rod 16 moves downward under the rotation of the first connecting rod 13, pushing the third connecting rod 18 to swing clockwise around hinge point B. This causes the swing arm 8 to swing towards the punch roller 1, and the pressure roller 2 to press against the punch roller 1. When the pressure roller 2 and the punch roller 1 are pressed together, the second connecting rod 16 is pressed together with the mounting base 15. The first hinge point 14 of the first connecting rod 13 and the second connecting rod 16 is above the second hinge point 17 of the first connecting rod 13 and the mounting base 15, and the included angle between the first connecting rod 13 and the second connecting rod 16 is no greater than 90 degrees. The two are in a self-locking state, and the force acting on the pressure roller 2 during rolling cannot cause the swing arm 8 to swing in the opposite direction. Thus, the pressure roller 2 and the punch roller 1 remain pressed together. By pulling the handle 10 upward with external force, the first connecting rod 13 swings counterclockwise around the hinge point A, and then the second connecting rod 16 is pulled upward to move the third connecting rod 18 counterclockwise around the hinge point B. Finally, the swing arm 8 swings in the opposite direction, and the pressure roller 2 separates from the punch roller 1.

[0029] The crossbeam 7 is provided with a first guide rail 11 and a second guide rail 12; the drive shaft 4 is a splined shaft, and the punch roller 1 is sleeved on the splined shaft and splinedly connected to the splined shaft. The punch roller 1 is rotatably mounted on the movable seat 3, and the movable seat 3 is slidably mounted on the first guide rail 11. The punch roller 1 can move laterally relative to the drive shaft 4 to adjust its lateral position on the frame, while the drive shaft 4 can drive the punch roller 1 to rotate. The mounting seat 15 is slidably mounted on the second guide rail 12. This utility model adjusts the lateral position of the punch roller 1 according to the Braille imprinting position, and the operator can also adjust the lateral position of the punch roller 1 according to the spatial position. In order to replace the punch template, the pressure roller 2 is adjusted accordingly to improve the speed and efficiency of replacement. A screw 5 is rotatably mounted on the base 6. The screw 5 is parallel to the first guide rail 11, and the movable seat 3 is threadedly connected to the screw. When the screw rotates, it drives the movable seat 3 to move laterally along the first guide rail 11, thereby realizing the adjustment of the lateral position of the punch roller 1.
