Description

Technical Field

[0001] This utility model relates to the technical field of cardboard processing, specifically to a conveying and buffering mechanism for a gluing machine. Background Technology

[0002] A box gluing machine is a machine that folds and glues printed and die-cut cardboard. In the packaging and printing industry, the application of box gluing machines is the final step in packaging box processing.

[0003] A conveying and buffering mechanism for a carton gluing machine is disclosed on the Chinese Patent Network (publication number CN217099057U). It includes a support platform with a conveyor belt on its top. A first mounting frame, a second mounting frame, and a third mounting frame are fixedly connected to the top of the support platform. A first screw is rotatably connected to one side of the first mounting frame, and a first turntable is fixedly connected to one end of the first screw. This conveying and buffering mechanism for the carton gluing machine, through a roller position adjustment structure, allows for the rotation of the first turntable during use. The first turntable drives the first screw, causing the first slider and the second slider to move simultaneously in opposite or opposing directions. The first and second sliders, in turn, drive a connecting rod, causing a fixed plate to move. The fixed plate, in turn, drives the third screw, causing a fixed frame to move. This, in turn, causes the fixed frame to move the rollers. This facilitates adjustment of the rollers according to different sizes of cardboard, reduces limitations in the device's use, and promotes its widespread adoption.

[0004] The following problems exist in this solution: The fixed frame drives the roller to move, which makes it easy to adjust the roller according to different sizes of cardboard. However, the roller is fixedly installed on the threaded rod by the fixed frame. If the roller is damaged during use, it is not easy to disassemble and replace it quickly. If it is damaged, it will affect the production efficiency and will not be able to continue to guide and adjust the cardboard. Therefore, it has low practicality and certain drawbacks. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a conveying and buffering mechanism for a box-gluing machine.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A conveying and buffering mechanism for a box-gluing machine includes a belt conveyor. Bearing frames are symmetrically installed at both ends of the top of the belt conveyor. A support frame is installed between the outer sides of the bearing frames. A servo motor is installed on the top of the support frame. The output shaft of the servo motor passes through the support frame and is connected to a rotating rod. Adjusting rods are symmetrically installed at both ends of the rotating rod. A movable frame is installed at one end of the adjusting rod. A buffer assembly is provided on the outside of the movable frame. Two sets of limiting plates are provided above the top of the belt conveyor. Connecting frames are symmetrically installed on both sides of the limiting plates. Adjusting bolts are installed on the connecting frames. A fixed seat is installed at the bottom of the adjusting bolt. A limiting frame is installed at the bottom of the fixed seat. Quick-release assemblies are provided on both sides of the limiting frame.

[0007] The beneficial effects of this utility model are as follows: When the servo motor drives the rotating rod to rotate, the rotation of the rotating rod will cause the adjusting rod to move the two movable frames closer or further apart, thereby causing the two limiting plates to move closer or further apart, which facilitates the limiting of cardboard of different sizes. When the product impacts the limiting plate, the first damper will directly absorb part of the impact force to play a buffering role. At the same time, the second damper on the support column will also extend and retract. The second damper will further absorb the impact force from different angles to enhance the buffering effect, protecting the product and the conveying equipment. By holding the handle and pulling it outward, the handle drives the telescopic rod to extend while the return spring is stretched. The limiting rod moves with the handle and exits from the limiting hole of the limiting block, so it can be taken out of the limiting frame. During installation, the limiting block is placed in the limiting frame and the handle is released. The return spring returns to its original state and drives the telescopic rod to shorten, so that the limiting rod is reinserted into the limiting hole, realizing the quick installation and fixing of the guide wheel. It is convenient to install and disassemble and has better practicality.

[0008] Furthermore, both ends of the rotating rod are hinged to one end of each of the two adjusting rods via pins. The end of the adjusting rod away from the rotating rod is hinged to the top of the movable frame via a pin. A guide rod is installed between the inner walls of the support frame. The outer ring surface of the guide rod is slidably connected to the interior of the two movable frames. The rotation of the rotating rod will cause the adjusting rod to move the two movable frames closer or further apart, thereby causing the two limiting plates to move closer or further apart, which facilitates the limiting of cardboard of different sizes.

[0009] Furthermore, the buffer assembly includes a first damper mounted on the outside of the movable frame, a support base mounted on one end of the first damper, and support columns symmetrically mounted on the outside of the movable frame and on both sides of the first damper. A second damper is hinged to the outside of the support columns via pins, and the end of the second damper away from the support columns is hinged to the outside of the support base via a pin. The first and second dampers enhance the buffering effect and protect the product and conveying equipment.

[0010] Furthermore, a limiting block is installed inside the limiting frame, and the inner wall size of the limiting frame is adapted to the outer side size of the limiting block. A mounting base is provided at the bottom of the limiting block and below the limiting frame, and a guide wheel is installed at the bottom of the mounting base. During product transportation, the guide wheel can contact the product and guide the product to be transported in the correct direction.

[0011] Furthermore, the outer ring surface of the adjusting bolt is threadedly connected to the inside of the connecting frame, the bottom of the adjusting bolt is rotatably connected to the top of the fixed seat, and the outside of the mounting seat is in contact with the outer side of the limiting plate. The height of the guide wheel can be adjusted to meet the conveying needs of products of different heights and sizes.

[0012] Furthermore, the quick-release assembly includes two telescopic rods installed on the outer sides of the limiting frame. A return spring is installed on the outer ring surface of the telescopic rods. A handle is installed on one end of the telescopic rods. A limiting rod is installed on the outside of the handle and between the two telescopic rods. A limiting hole is opened on the outside of the limiting block. One end of the limiting rod extends to the inside of the limiting frame and enters the inside of the limiting hole, thereby realizing the quick installation and fixation of the guide wheel.

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0018] Example 1 Figure 1 This is a schematic diagram of the overall structure of a conveying and buffering mechanism for a box-gluing machine, provided by an embodiment of the present invention. Figure 2 This is a schematic diagram of the support frame structure of this utility model. Figure 1 , Figure 2 As shown, the device includes a belt conveyor 1. The belt conveyor 1 has symmetrically mounted support frames 2 at both ends of its top. A support frame 3 is installed between the outer sides of the support frames 2. A servo motor 4 is mounted on the top of the support frame 3. The output shaft of the servo motor 4 passes through the support frame 3 and is mounted on a rotating rod 5. Adjusting rods 6 are symmetrically mounted on both ends of the rotating rod 5. A movable frame 7 is mounted on one end of the adjusting rod 6. A buffer assembly 8 is provided on the outside of the movable frame 7. Two sets of limiting plates 9 are provided above the top of the belt conveyor 1. Connecting frames 10 are symmetrically mounted on both sides of the limiting plates 9. Adjusting bolts 11 are mounted on the connecting frames 10. A fixed seat 12 is mounted at the bottom of the adjusting bolts 11. A limiting frame 13 is mounted at the bottom of the fixed seat 12. Quick-release assemblies 14 are provided on both sides of the limiting frame 13.

[0019] The belt conveyor 1 is used to transport cardboard products. The carrier frame 2 and the support frame 3 provide support for the overall structure. The servo motor 4 starts its output shaft to drive the rotating rod 5 to rotate. The rotation of the rotating rod 5 drives the movable frame 7 to move through the adjusting rod 6. The buffer component 8 on the movable frame 7 can buffer the products during the conveying process. The limiting plate 9 is used to limit the lateral position of the products during the conveying process. By rotating the adjusting bolt 11, the fixed seat 12 and the limiting frame 13 can be moved up and down.

[0020] Both ends of the rotating rod 5 are hinged to one end of the two adjusting rods 6 by a pin. The end of the adjusting rod 6 away from the rotating rod 5 is hinged to the top of the movable frame 7 by a pin. A guide rod 15 is installed between the inner side walls of the support frame 3. The outer ring surface of the guide rod 15 is slidably connected to the inside of the two movable frames 7.

[0021] When the servo motor 4 drives the rotating rod 5 to rotate, since the rotating rod 5 and the adjusting rod 6 are hinged by a pin, and the adjusting rod 6 and the movable frame 7 are also hinged by a pin, the rotation of the rotating rod 5 will cause the adjusting rod 6 to drive the two movable frames 7 to move closer or further away from each other, and in turn drive the two limiting plates 9 to move closer or further away from each other, so as to limit the cardboard of different sizes. The guide rod 15 plays a guiding role to ensure that the two movable frames 7 will not deviate during the movement.

[0022] Figure 3 This is a schematic diagram of a portion of the buffer component of this utility model. Figure 5 This is an enlarged schematic diagram of part A of the structure of this utility model. (See attached diagram.) Figure 3 , Figure 5 As shown, the buffer assembly 8 includes a first damper 16 mounted on the outside of the movable frame 7. A support base 17 is mounted on one end of the first damper 16. Support columns 18 are symmetrically mounted on the outside of the movable frame 7 and on both sides of the first damper 16. A second damper 19 is hinged to the outside of the support columns 18 by a pin. The end of the second damper 19 away from the support column 18 is hinged to the outside of the support base 17 by a pin.

[0023] When the product impacts the limit plate 9, the first damper 16 will directly absorb part of the impact force to play a buffering role. At the same time, the second damper 19 on the support column 18 will also extend and retract. Since the second damper 19 is hinged to the support base 17 and the support column 18 through a pin, when the product impacts the limit plate 9, the second damper 19 will further absorb the impact force from different angles to enhance the buffering effect and protect the product and the conveying equipment.

[0024] Figure 4 This is a schematic diagram of the quick-release component of this utility model. (See attached diagram.) Figure 4As shown, a limiting block 20 is installed inside the limiting frame 13. The inner wall size of the limiting frame 13 is adapted to the outer side size of the limiting block 20. A mounting base 21 is provided at the bottom of the limiting block 20 and below the limiting frame 13. A guide wheel 22 is installed at the bottom of the mounting base 21.

[0025] The limiting block 20 is installed inside the limiting frame 13. The inner wall size of the limiting frame 13 is adapted to the outer side size of the limiting block 20, which can ensure that the limiting block 20 is stably installed inside the limiting frame 13. The mounting base 21 is connected to the limiting block 20 and the guide wheel 22 is installed at the bottom of the mounting base 21. During the product conveying process, the guide wheel 22 can contact the product and guide the product to be conveyed in the correct direction.

[0026] The quick-release assembly 14 includes two telescopic rods 23 mounted on the outer sides of the limiting frame 13. A return spring 24 is mounted on the outer ring surface of the telescopic rods 23. A handle 25 is mounted on one end of the telescopic rods 23. A limiting rod 26 is mounted on the outside of the handle 25 and between the two telescopic rods 23. A limiting hole 2001 is opened on the outside of the limiting block 20. One end of the limiting rod 26 extends to the inside of the limiting frame 13 and enters the inside of the limiting hole 2001.

[0027] When the guide wheel 22 needs to be removed, grasp the handle 25 and pull it outward. The handle 25 causes the telescopic rod 23 to extend, and the return spring 24 is stretched. The limit rod 26 moves with the handle 25 and exits from the limit hole 2001 of the limit block 20. At this time, the limit block 20 is no longer limited and can be taken out from the limit frame 13. When installing, put the limit block 20 into the limit frame 13 and release the handle 25. The return spring 24 returns to its original state and causes the telescopic rod 23 to shorten, so that the limit rod 26 is reinserted into the limit hole 2001, thus realizing the quick installation and fixation of the guide wheel 22.

[0028] Example 2 Based on the above embodiments, this embodiment also makes the following improvements, such as... Figure 3 As shown, The outer ring surface of the adjusting bolt 11 is threadedly connected to the inside of the connecting bracket 10, the bottom of the adjusting bolt 11 is rotatably connected to the top of the fixed seat 12, and the outside of the mounting seat 21 is in contact with the outer side of the limiting plate 9.

[0029] By rotating the adjusting bolt 11, which is threadedly connected to the connecting frame 10, the adjusting bolt 11 will move up and down within the connecting frame 10. Since the bottom of the adjusting bolt 11 is rotatably connected to the fixed seat 12, the up and down movement of the adjusting bolt 11 will drive the fixed seat 12 to move up and down, thereby driving the limiting frame 13, the limiting block 20, the mounting seat 21, and the guide wheel 22 to move up and down, so as to adjust the height of the guide wheel 22 to meet the conveying needs of products of different heights and sizes. The mounting seat 21 is in contact with the outer side of the limiting plate 9, which can ensure the stability of the lifting and lowering of the guide wheel 22.

[0030] The implementation principle of the conveying buffer mechanism of the gluing machine according to this utility model embodiment is as follows: When the equipment is used, when the servo motor 4 drives the rotating rod 5 to rotate, since the rotating rod 5 and the adjusting rod 6 are hinged by a pin, and the adjusting rod 6 and the movable frame 7 are also hinged by a pin, the rotation of the rotating rod 5 will cause the adjusting rod 6 to drive the two movable frames 7 to move closer or further away from each other, thereby driving the two limiting plates 9 to move closer or further away from each other, which facilitates the limiting of cardboard of different sizes. The guide rod 15 plays a guiding role to ensure that the two movable frames 7 will not deviate during the movement. When the product impacts the limiting plate 9, the first damper 16 will directly absorb part of the impact force to play a buffering role, while supporting... The second damper 19 on column 18 will also extend and retract. Since the second damper 19 is hinged to the support base 17 and the support column 18 by a pin, when the product impacts the limiting plate 9, the second damper 19 will further absorb the impact force from different angles to enhance the buffering effect and protect the product and the conveying equipment. The limiting block 20 is installed in the limiting frame 13. The inner wall size of the limiting frame 13 is adapted to the outer side size of the limiting block 20, which can ensure that the limiting block 20 is stably installed in the limiting frame 13. The mounting base 21 is connected to the limiting block 20 and the guide wheel 22 is installed at the bottom of the mounting base 21. During the product conveying process, the guide wheel 22 can contact the product and guide the product to be conveyed in the correct direction. By rotating the adjusting bolt 11, which is threadedly connected to the connecting frame 10, the adjusting bolt 11 moves up and down within the connecting frame 10. Since the bottom of the adjusting bolt 11 is rotatably connected to the fixed seat 12, the up-and-down movement of the adjusting bolt 11 causes the fixed seat 12 to move up and down, which in turn causes the limiting frame 13, the limiting block 20, the mounting seat 21, and the guide wheel 22 to move up and down. This allows for the adjustment of the guide wheel 22's height to accommodate products of different heights and dimensions. The mounting seat 21 fits snugly against the outer side of the limiting plate 9, ensuring the stability of the guide wheel 22's lifting and lowering. When removing the guide wheel 22, grasp the handle 25 and pull it outward. The handle 25 causes the telescopic rod 23 to extend, and the return spring 24 is stretched. The limiting rod 26 moves with the handle 25 and exits from the limiting hole 2001 of the limiting block 20. At this time, the limiting block 20 is no longer limited and can be removed from the limiting frame 13. When installing, put the limiting block 20 into the limiting frame 13 and release the handle 25. The return spring 24 returns to its original state and causes the telescopic rod 23 to shorten, so that the limiting rod 26 is reinserted into the limiting hole 2001, realizing the quick installation and fixation of the guide wheel 22. It is convenient to install and remove and has better practicality.
