Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, specifically to a crease assembly for packaging cardboard boxes. Background Technology

[0002] The typical process for manufacturing cardboard boxes involves first drying the layers of paper and then bonding them together to form corrugated cardboard. Next, creases are rolled and grooves are cut on the corrugated cardboard, and finally, the cardboard is folded along the creases to form a box. To ensure the cardboard can be assembled into a complete box, a crease-pressing device is needed to crease different positions on the cardboard. However, existing cardboard crease-pressing devices can only crease the cardboard once. If multiple creases are needed, the cardboard must be moved and repositioned before crease processing can begin. This method is not only cumbersome but also cannot guarantee the accuracy of the crease placement, which can easily lead to deformation when the cardboard is assembled into a box.

[0003] Referring to Chinese Patent No. CN218286901U, a crease device for cardboard box processing is disclosed. It controls the spacing between two crease components through a bidirectional module slide, and can then work with a lifting processing table to perform multiple crease processing on cardboard at different positions. At the same time, it can achieve rapid crease processing on cardboard without moving the cardboard, which can effectively improve the accuracy of the crease position and prevent the cardboard from deforming after being spliced ​​into a carton.

[0004] Generally, creases on cardboard are divided into two types: one extends along the length of the cardboard, and the other extends along the width of the cardboard. However, when the aforementioned cardboard crease processing device uses an extruder to process creases after positioning the cardboard, the extruder's extension direction is fixed, so it can only process creases in the corresponding extension direction. It cannot process creases in both extension directions. The cardboard must be unpositioned and repositioned before secondary processing can be performed, which is inefficient. Utility Model Content

[0005] The purpose of this invention is to provide a crease assembly for packaging cartons, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A crease assembly for a packaging carton includes an assembly frame, a drive mechanism, a mounting base, a lifting platform, a moving module, and a crease mechanism. The mounting base is installed in the assembly frame via a drive mechanism located at the bottom of the assembly frame. The drive mechanism is used to drive the mounting base to rotate and adjust. The lifting platform is arranged on the mounting base and is used to drive the cardboard to rise and fall and adjust. The crease mechanism is arranged in the assembly frame and above the lifting platform via a moving module located at the top of the assembly frame. The moving module is used to drive the crease mechanism to translate and adjust.

[0008] Therefore, by arranging the lifting platform on the mounting base and arranging a drive mechanism that can drive the mounting base and the lifting platform to rotate and adjust within the assembly frame, after completing the processing of each crease extending along the width direction of the cardboard, without adjusting the cardboard for repositioning, the drive mechanism can be used to rotate the mounting base, the lifting platform, and the cardboard as a whole by 90 degrees, so that the processing of each crease extending along the length direction of the cardboard can continue. This ensures high processing continuity, saves time and effort, and is highly efficient.

[0009] Furthermore, the drive mechanism includes a shaft, a driven gear, a drive motor, and a main gear. The shaft is rotatably mounted at the bottom of the assembly frame and extends vertically upward. The mounting base is fixed to the top of the shaft. The drive motor is fixed at the bottom of the assembly frame. The main gear is fixed on the output shaft of the drive motor. The driven gear is fixedly mounted on the shaft and meshes with the main gear.

[0010] Furthermore, the lifting platform includes an electric push cylinder A and a placement platform. The electric push cylinder A is vertically fixed on the upper surface of the mounting base, and the placement platform is fixed on the end of the telescopic rod of the electric push cylinder A.

[0011] Furthermore, the crease mechanism includes a pressure strip, a connecting seat, a bracket, and guide rods. The moving module adopts an electric lead screw structure. The connecting seat is fixed on the moving end of the moving module, the pressure strip is fixed on the bottom of the connecting seat, the two brackets are fixed on the top two sides of the assembly frame respectively, and two guide rods are fixed between the two brackets. The connecting seat is slidably fitted on the two guide rods.

[0012] Furthermore, a reference positioning plate A is provided on one side of the placement platform, and a reference positioning plate B is provided on the side adjacent to the reference positioning plate A. The extension direction of the reference positioning plate A is parallel to the length direction of the cardboard, and the extension direction of the reference positioning plate B is parallel to the width direction of the cardboard.

[0013] Furthermore, the placement platform is provided with vertically connected sliding grooves A and B. Reference positioning plate A is slidably installed in sliding groove A, and reference positioning plate B is slidably installed in sliding groove B. An electric push cylinder B is vertically fixed on the lower surface of the placement platform. A connecting arm is fixed to the end of the telescopic rod of the electric push cylinder B. A connecting frame is fixedly connected to the bottom ends of reference positioning plate A and reference positioning plate B. The connecting frame is fixedly connected to the connecting arm.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] This invention arranges a lifting platform on a mounting base and a drive mechanism within the assembly frame to rotate and adjust the mounting base and lifting platform. After processing each crease extending along the width of the cardboard, without adjusting the cardboard for repositioning, the drive mechanism rotates the mounting base, lifting platform, and cardboard as a whole by 90 degrees, allowing processing of each crease extending along the length of the cardboard to continue. This ensures high processing continuity, saves time and effort, and is highly efficient.

[0016] This invention allows for precise positioning of cardboard when it is positioned on the placement table. One side of the cardboard is pressed against the reference positioning plate A, and the other side is pressed against the reference positioning plate B. Simultaneously, the electric push cylinder B extends and retracts, and with the connection of the connecting arm and the connecting frame, the reference positioning plates A and B can be synchronously raised and lowered. When positioning the cardboard, the reference positioning plates A and B are moved upwards to the top of the placement table. After positioning, the reference positioning plates A and B are moved downwards and retracted into the slide grooves A and B respectively, preventing the reference positioning plates A and B from protruding and obstructing the pressure strip.

Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0024] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] Please see Figures 1-4 The present invention provides a crease assembly for a packaging carton, comprising an assembly frame 1, a drive mechanism 2, a mounting base 3, a lifting platform 4, a moving module 5, and a crease mechanism 6. The mounting base 3 is mounted in the assembly frame 1 via the drive mechanism 2 located at the bottom of the assembly frame 1. The drive mechanism 2 is used to drive the mounting base 3 to rotate and adjust. The lifting platform 4 is arranged on the mounting base 3 and is used to drive the cardboard to lift and adjust. The crease mechanism 6 is arranged in the assembly frame 1 and above the lifting platform 4 via the moving module 5 located at the top of the assembly frame 1. The moving module 5 is used to drive the crease mechanism 6 to move and adjust.

[0026] When using the crease assembly of this packaging carton to crease the cardboard, the cardboard is first placed on the lifting platform 4 and positioned. Then, the moving module 5 drives the crease mechanism 6 to move to the first position where a crease needs to be made. Next, the lifting platform 4 moves the cardboard upward until it contacts the crease mechanism 6, completing the first crease on the cardboard. Then, the lifting platform 4 moves downward and moves the cardboard back. The moving module 5 moves the crease mechanism 6 to the second position where a crease needs to be made. Then, the lifting platform 4 moves the cardboard upward until it contacts the crease mechanism 6, completing the second crease on the cardboard. This process is repeated to complete all the creases extending along the width of the cardboard.

[0027] After completing the processing of each crease extending along the width of the cardboard, the drive mechanism 2 drives the mounting base 3, the lifting platform 4 and the cardboard to rotate 90 degrees, so that the length direction of the cardboard is parallel to the extension direction of the crease mechanism 6. Then, the processing of each crease extending along the length direction of the cardboard is completed in sequence. The specific processing steps are the same as those described above.

[0028] This utility model arranges the lifting platform 4 on the mounting base 3 and arranges the drive mechanism 2 in the assembly frame 1 to drive the mounting base 3 and the lifting platform 4 to rotate and adjust. After completing the processing of each crease extending along the width direction of the cardboard, without adjusting the cardboard to reposition, the drive mechanism 2 drives the mounting base 3, the lifting platform 4 and the cardboard to rotate 90 degrees as a whole, so that the processing of each crease extending along the length direction of the cardboard can continue. This ensures high processing continuity, saves time and effort, and is highly efficient.

[0029] Specifically, the drive mechanism 2 includes a shaft 21, a driven gear 22, a drive motor 23, and a main gear 24. The shaft 21 is rotatably mounted at the bottom of the assembly frame 1 and extends vertically upward. The mounting base 3 is fixed to the top of the shaft 21. The drive motor 23 is fixed to the bottom of the assembly frame 1. The main gear 24 is fixed on the output shaft of the drive motor 23. The driven gear 22 is fixedly mounted on the shaft 21 and meshes with the main gear 24. When the drive motor 23 works, its output shaft can drive the main gear 24 to rotate. The rotating main gear 24 meshes with and drives the driven gear 22, which in turn drives the shaft 21 to rotate, thereby driving the mounting base 3 and the lifting platform 4 to rotate, providing drive for the cardboard's rotation adjustment.

[0030] Specifically, the lifting platform 4 includes an electric push cylinder A41 and a placement platform 42. The electric push cylinder A41 is vertically fixed on the upper surface of the mounting base 3, and the placement platform 42 is fixed on the end of the telescopic rod of the electric push cylinder A41. After the cardboard is positioned on the placement platform 42, the electric push cylinder A41 can extend and retract to drive the placement platform 42 and the cardboard to move up and down, providing a drive for the up and down adjustment of the cardboard.

[0031] Specifically, the crease mechanism 6 includes a pressure strip 61, a connecting seat 62, a bracket 63, and a guide rod 64. The moving module 5 adopts an electric lead screw structure. The connecting seat 62 is fixed on the moving end of the moving module 5, and the pressure strip 61 is fixed on the bottom of the connecting seat 62. The motor in the electric lead screw structure drives the lead screw to rotate, and the lead screw drives the moving seat to move, which in turn drives the pressure strip 61 and the connecting seat 62 to adjust their positions so as to process creases at different positions.

[0032] In addition, two brackets 63 are fixed on the top two sides of the assembly frame 1 respectively, and two guide rods 64 are fixed between the two brackets 63. The connecting seat 62 is slidably fitted on the two guide rods 64. The guide rods 64 can provide a limiting and guiding function for the movement adjustment of the connecting seat 62 and the pressure strip 61, thereby ensuring that the movement adjustment of the pressure strip 61 and the connecting seat 62 is smoother and more stable.

[0033] Specifically, a reference positioning plate A7 is provided on one side of the placement table 42, and a reference positioning plate B8 is provided on the side adjacent to the reference positioning plate A7. The extension direction of the reference positioning plate A7 is parallel to the length direction of the cardboard, and the extension direction of the reference positioning plate B8 is parallel to the width direction of the cardboard. When positioning the cardboard on the placement table 42, one side of the cardboard is pressed against the reference positioning plate A7 and the other side is pressed against the reference positioning plate B8, which can achieve precise positioning of the cardboard. Then the cardboard is fixed to prevent the cardboard from moving or shifting during the crease processing, and to ensure the stability of the crease processing. The specific fixing method is the same as that in the reference patent, and will not be described again.

[0034] Specifically, the placement platform 42 is provided with vertically connected sliding grooves A71 and B81. Reference positioning plate A7 is slidably installed in sliding groove A71, and reference positioning plate B8 is slidably installed in sliding groove B81. An electric push cylinder B9 is vertically fixed to the lower surface of the placement platform 42. A connecting arm 91 is fixed to the end of the telescopic rod of the electric push cylinder B9. A connecting frame 92 is fixedly connected to the bottom ends of reference positioning plates A7 and B8. The connecting frame 92 is fixedly connected to the connecting arm 91. The electric push cylinder B9 extends and retracts to... Under the connection of the connecting arm 91 and the connecting frame 92, the reference positioning plate A7 and the reference positioning plate B8 can be synchronously raised and lowered. When positioning the cardboard, the reference positioning plate A7 and the reference positioning plate B8 can be moved upward to rise above the placement table 42. After positioning is completed, the reference positioning plate A7 and the reference positioning plate B8 can be moved downward to retract into the slide groove A71 and the slide groove B81 respectively. This can prevent the reference positioning plate A7 and the reference positioning plate B8 from protruding upward and causing obstruction or interference to the pressure strip 61.

[0035] In addition, it is worth noting that the control method in this application is automatic control through a controller. The controller's control circuit adopts existing conventional technology, and the control program can be implemented by those skilled in the art through simple programming. It is common knowledge in the field, so this application will not explain the control method and circuit connection in detail.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
