Description

Technical Field

[0001] This utility model belongs to the field of cardboard creasing technology, and in particular relates to a honeycomb cardboard crease pressing mechanism. Background Technology

[0002] Honeycomb paperboard is a lightweight and high-strength material made based on the honeycomb structure principle. It has advantages such as light weight, high strength and good cushioning performance and is widely used in the packaging field. When making honeycomb paperboard boxes or honeycomb paperboard products of specific shapes, it is often necessary to press crease lines on its surface so that it can be folded and formed accurately in the future.

[0003] Currently, the creasing rollers of existing creasing pressing mechanisms are usually directly mounted on a fixed shaft, and their positions are fixed and cannot be adjusted. When facing the production needs of honeycomb paperboard products of different specifications or shapes, it is necessary to adjust the crease spacing or position according to the new folding requirements. This can be achieved by disassembling and reinstalling the creasing rollers or replacing the fixed shafts of different specifications. The operation is cumbersome and time-consuming, which affects production efficiency and increases the production costs of enterprises.

[0004] To address the aforementioned problems, this application proposes a crease pressing mechanism for honeycomb cardboard. Utility Model Content

[0005] The purpose of this invention is to provide a honeycomb cardboard crease pressing mechanism, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a honeycomb cardboard crease pressing mechanism, comprising a conveyor and a fixed column horizontally positioned above the conveyor. Multiple annular movable sleeves are slidably fitted around the fixed column, and crease rollers are rotatably mounted on the outer walls of the annular movable sleeves. The annular movable sleeves are connected to a lifting gantry frame via a transmission mechanism. The transmission mechanism is used to push the annular movable sleeves to move horizontally along the fixed column. An electric push rod is installed on the top surface of the fixed gantry frame fixed to the top surface of the conveyor. A fixed plate is fixed to the side wall of the lifting gantry frame, and the output end of the electric push rod is fixedly connected to the top surface of the fixed plate. The fixed column is fixed inside the lifting gantry frame, and the electric push rod is used to drive the lifting gantry frame to move vertically and adjust the height of the fixed column.

[0008] Furthermore, the transmission mechanism includes a connecting rod and a lifting plate. One side of the annular moving sleeve and the bottom end of the lifting plate are both fixed with hinge seats that are hinged to both ends of the connecting rod. The top plate of the lifting gantry frame is penetrated by a vertical internal threaded sleeve, and the internal threaded sleeve is threadedly connected to a screw fixed to the top of the lifting plate.

[0009] Furthermore, the internal threaded sleeve is rotatably connected to the lifting gantry frame, and the lifting gantry frame has the same number of cavities as the annular movable sleeve. The cavities are equipped with bevel gear one and bevel gear two that mesh with each other. The bevel gear one is fixedly connected to the outer wall of the internal threaded sleeve, and the bevel gear two is fixedly connected to the knobs provided on the side of the lifting gantry frame through connecting shafts.

[0010] Furthermore, a guide telescopic rod is fixed between the lifting plate and the top plate of the lifting gantry frame, and the guide telescopic rod is arranged parallel to the screw.

[0011] Furthermore, a limiting block is fixed at the top end of the screw, and the diameter of the limiting block is larger than the diameter of the screw.

[0012] Furthermore, the fixed gantry frame has the same number of clearance holes as the annular moving sleeve, and the clearance holes are used for the limit block to pass through.

[0013] Furthermore, the outer wall of the fixed column is circumferentially fixed with a guide rail, and the annular movable sleeve is provided with a guide groove that is slidably connected to the guide rail.

[0014] This utility model has the following beneficial effects:

[0015] This invention uses a transmission mechanism to independently control the corresponding annular moving sleeves to slide horizontally along the fixed column, thereby adjusting the horizontal position of the embossing rollers and achieving precise adjustment of the distance between adjacent embossing rollers to meet the pressing requirements of different crease line spacings.

[0016] This invention uses an electric push rod to drive the fixed plate to move vertically, which in turn drives the lifting gantry frame to rise and fall. The indentation wheels rise and fall synchronously with the lifting gantry frame through the annular moving sleeve and the fixed column. This allows for synchronous and rapid adjustment of the height of all indentation wheels relative to the working surface of the conveyor, thereby uniformly controlling the indentation depth.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figure 1 - Figure 4 As shown, this utility model is a honeycomb cardboard crease pressing mechanism, including a conveyor 1 and a fixed column 4, which is horizontally arranged above the conveyor 1. Multiple annular movable sleeves 5 are slidably sleeved on the outside of the fixed column 4, and crease wheels 6 are rotatably installed on the outer wall of the annular movable sleeves 5. The annular movable sleeves 5 are respectively connected to the lifting gantry frame 3 through a transmission mechanism. The transmission mechanism is used to push the annular movable sleeves 5 to move horizontally along the fixed column 4. An electric push rod 15 is installed on the top surface of the fixed gantry frame 2 fixed on the top surface of the conveyor 1. A fixed plate 301 is fixed on the side wall of the lifting gantry frame 3. The output end of the electric push rod 15 is fixedly connected to the top surface of the fixed plate 301. The fixed column 4 is fixed inside the lifting gantry frame 3. The electric push rod 15 is used to drive the lifting gantry frame 3 to move vertically and adjust the height of the fixed column 4.

[0028] This embodiment provides a honeycomb paperboard crease pressing mechanism. The conveyor 1 is used to transport the honeycomb paperboard. The horizontal movement of the annular moving sleeve 5 is adjusted by the transmission mechanism, thereby adjusting the distance between adjacent crease rollers 6 and controlling the spacing of the crease lines pressed by the honeycomb paperboard to meet the processing requirements of different crease spacing. The lifting gantry 3 is pushed vertically by the electric push rod 15, which can adjust the height of all crease rollers 6 relative to the working surface of the conveyor 1 at one time and synchronously. This not only makes the device suitable for processing honeycomb paperboard of different thicknesses, but also controls the depth of the crease.

[0029] The transmission mechanism includes a connecting rod 7 and a lifting plate 8. One side of the annular moving sleeve 5 and the bottom end of the lifting plate 8 are both fixed with hinge seats that are hinged to both ends of the connecting rod 7. The top plate of the lifting gantry frame 3 is penetrated by a vertical internal threaded sleeve 10, and the internal threaded sleeve 10 is threadedly connected to a screw 9 that is fixed to the top end of the lifting plate 8. When the screw 9 rotates relative to the internal threaded sleeve 10, it can drive the lifting plate 8 to move vertically, thereby pushing the annular moving sleeve 5 to move horizontally along the fixed column 4 through the connecting rod 7.

[0030] The internal threaded sleeve 10 is rotatably connected to the lifting gantry frame 3. The lifting gantry frame 3 has the same number of cavities 302 as the annular moving sleeve 5. The cavity 302 is provided with a meshing bevel gear 11 and a bevel gear 2 12. The bevel gear 11 is fixedly connected to the outer wall of the internal threaded sleeve 10. The bevel gear 2 12 is fixedly connected to the knobs 13 provided on the side of the lifting gantry frame 3 through connecting shafts. Rotating the knobs 13 drives the bevel gear 11 to rotate through the bevel gear 2 12, which in turn drives the internal threaded sleeve 10 to rotate, realizing the vertical movement of the screw 9. The number of knobs 13 is the same as the number of annular moving sleeves 5. The position of the corresponding indentation wheel 6 can be adjusted independently by each knob 13.

[0031] A guide telescopic rod 14 is fixed between the lifting plate 8 and the top plate of the lifting gantry frame 3, and the guide telescopic rod 14 is set parallel to the screw 9. The guide telescopic rod 14 guides the lifting plate, so that the lifting plate 8 can move smoothly in the vertical direction.

[0032] The screw 9 has a limiting block 901 fixed at its top end, and the diameter of the limiting block 901 is larger than the diameter of the screw 9. The limiting block 901 is used to prevent the screw 9 from completely disengaging from the internal threaded sleeve 10 when it descends.

[0033] The fixed gantry frame 2 has the same number of clearance holes 201 as the annular moving sleeve 5. The clearance holes 201 are used for the limit block 901 to pass through. When the lifting gantry frame 3 moves vertically, the limit block 901 can pass through the clearance holes 201, providing space for the limit block 901 and the screw 9 to move up and down, and preventing structural interference between the limit block 901 and the lifting gantry frame 3.

[0034] The outer wall of the fixed column 4 is circumferentially fixed with a guide rail 401, and the annular moving sleeve 5 is provided with a guide groove 501 that is slidably connected to the guide rail 401. The guide rail 401 and the guide groove 501 cooperate to ensure that the annular moving sleeve 5 can only slide smoothly along the axial direction of the fixed column 4 and cannot rotate around the fixed column 4, thus ensuring the accuracy and stability of the movement direction of the indentation wheel 6.

[0035] It is understood that this utility model can adjust the spacing of the creasing rollers 6 to press out creases with different spacings, and then adjust the height of the creasing rollers 6 to perform crease pressing processing on honeycomb cardboard of different thicknesses.

[0036] A specific application of the operation process in this embodiment is as follows: based on the thickness of the honeycomb paperboard, the fixed plate 301 is moved vertically by the electric push rod 15, which further pushes the lifting gantry frame 3 to move, and adjusts the height of the creasing wheel 6. The user can also control the creasing depth of the honeycomb paperboard by adjusting the vertical height of the creasing wheel 6.

[0037] The knob 13 drives the bevel gear 12 to rotate, which in turn drives the internal threaded sleeve 10 to rotate via the bevel gear 11. Since the screw 9 is threadedly engaged with the internal threaded sleeve 10 and the screw 9 cannot rotate due to the restriction of the guide telescopic rod 14, the rotation of the internal threaded sleeve 10 drives the screw 9 and the lifting plate 8 to move vertically. This, in turn, drives the annular moving sleeve 5 to slide horizontally along the fixed column 4 via the connecting rod 7, thereby adjusting the horizontal position of the indentation wheel 6.
