Description
Technical Field
[0001] This utility model relates to the field of embossing machine technology, and in particular to a logo embossing device for packaging boxes. Background Technology
[0002] In the packaging industry, logo embossing on the surface of packaging boxes is a key process for enhancing product recognition and brand image. Currently, this process is mainly achieved through embossing machines, which rely on the embossing mechanism to apply specific pressure to the surface of the packaging box, creating a clear indentation of the logo on the packaging material. However, in the actual embossing process, since packaging boxes are mostly made of paper, plastic, or composite materials, material debris (such as paper fiber fragments, plastic microparticles, etc.) is easily generated when the embossing mechanism comes into contact with the surface of the packaging box and applies pressure.
[0003] Existing embossing equipment generally lacks a dedicated debris handling structure, causing debris to accumulate directly on the surface of the embossing station's support table, in the gaps between the embossing head, and around the equipment. Long-term accumulation leads to several problems: First, it affects embossing accuracy. Debris between the packaging box and the support table, or adhering to the embossing head, can cause misalignment, blurring, or partial loss of the logo. Second, it increases the risk of equipment malfunction. Debris entering internal transmission components (such as guide rails and gears) can easily cause jamming and wear, shortening the equipment's lifespan. Manually wiping or blowing away debris is not only time-consuming but may also lead to recurring processing problems due to incomplete cleaning, severely impacting overall production efficiency.
[0004] There is an urgent need to design an integrated device that combines embossing and debris removal functions. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies that generate a large amount of dust after processing, and to propose a packaging box logo embossing device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a packaging box logo embossing device, comprising a main body and a cleaning component. A support frame is vertically fixedly mounted on the top surface of the main body. A logo embossing mechanism for embossing logos onto packaging boxes is vertically suspended from the bottom surface of the crossbeam of the support frame. A packaging box support platform for placing the packaging boxes to be embossed is horizontally fixedly mounted on the top surface of the main body, directly below the logo embossing mechanism. An operation control panel is fixedly connected to the top surface of the main body, near the packaging box support platform. One side wall of the support frame is vertically fixed... A maintenance ladder is provided. The cleaning assembly is mounted on the top surface of the main body of the equipment. The cleaning assembly includes a debris adsorption panel. Several dust suction heads are arrayed on the side of the debris adsorption panel facing the packaging box support platform. One end of the debris adsorption panel is rotatably connected to the top surface of the main body of the equipment via a hinge, and can be flipped around the hinge axis to move closer to or away from the packaging box support platform. A dust conveying hose is fixedly connected to the side of the debris adsorption panel away from the hinge. A through hole is provided on the top surface of the main body of the equipment corresponding to the position of the dust conveying hose. The end of the dust conveying hose away from the debris adsorption panel is detachably inserted into the through hole on the surface of the main body of the equipment.
[0007] Preferably, the feature is that: a positioning block is vertically fixedly connected to the side of the debris adsorption panel away from the dust collection head and near the edge; and a fixing mounting base is vertically fixedly connected to the top surface of the main body of the device and the side corresponding to the positioning block.
[0008] Preferably, the fixed mounting base has a buckle plate rotatably connected to the side surface facing the positioning block via a rotating shaft. The buckle plate can rotate around the axis of the rotating shaft to abut or dismount from the top surface of the positioning block. The longitudinal section of the fixed mounting base is L-shaped, with its horizontal section fixed to the surface of the main body of the equipment and its vertical section used to assemble the buckle plate.
[0009] Preferably, the feature is that: a reset pressure spring is fixedly connected between the side of the buckle plate away from the positioning block and the inner wall of the vertical section of the fixed mounting base. The reset pressure spring is always in a pre-compressed state and can apply a spring force towards the positioning block to the buckle plate, driving the buckle plate to maintain the abutment and positioning state with the positioning block.
[0010] Preferably, the feature is that: a collection device is provided on the lower surface of the main body of the equipment, and at the position directly below the through hole. The collection device includes a dust collection box. A placement plate is fixedly provided on the lower surface of the main body of the equipment in the horizontal direction. The dust collection box is placed horizontally on the placement plate. A flexible hose connection port is opened on the top wall of the dust collection box at the position corresponding to the through hole of the main body of the equipment. One end of the dust conveying hose passes through the through hole of the main body of the equipment and is detachably inserted and engaged with the flexible hose connection port on the surface of the dust collection box to form a dust conveying channel.
[0011] Preferably, the dust collection box has a guide groove in the middle of one side wall, and a movable door plate is slidably connected to the inner wall of the guide groove on the surface of the dust collection box in the horizontal direction. The movable door plate can slide horizontally along the inner wall of the guide groove to open or close the space inside the dust collection box. A sliding sleeve is fixedly connected to the top of the side wall away from the movable door plate of the dust collection box, and a snap-fit hook is slidably connected to the inner wall of the sliding sleeve in the horizontal direction. The snap-fit hook can slide horizontally along the inner wall of the sliding sleeve.
[0012] Preferably, the feature is that: a positioning spring is fixedly connected between the outer surface of the end of the snap hook away from the main body of the equipment and the end of the sliding sleeve. The positioning spring is always in a pre-stretched state and can apply an elastic force to the snap hook in the direction of the main body of the equipment. A limiting groove is opened on the surface of the placement plate below the main body of the equipment corresponding to the position of the snap hook. Under the action of the elastic force of the positioning spring, the snap hook can be horizontally inserted into the limiting groove to realize the positioning and fixing of the dust collection box on the placement plate.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, by setting up a cleaning component, this device sets up a flip-adjustable debris adsorption panel next to the embossing station, which, together with a negative pressure fan, forms a real-time dust collection system. It can simultaneously remove debris generated during the logo embossing process, preventing debris from accumulating on the packaging box carrier or the surface of the embossing head of the logo embossing mechanism. This ensures that the embossing head and the surface of the packaging box always maintain a stable fit, effectively reducing problems such as embossing misalignment and blurry patterns caused by debris, significantly improving the consistency and clarity of the logo embossing on the packaging box, and ensuring stable product quality.
[0015] 2. In this utility model, by setting up a collection device, compared with the existing equipment that requires manual periodic shutdown for cleaning, this device achieves closed-loop processing from the generation of debris to its adsorption and collection through the coordinated design of the cleaning components and the collection device. After the debris is sucked in by the debris adsorption panel, it is directly transported to the dust collection box through the dust conveying hose, eliminating the need for frequent manual wiping of the equipment interior and workstation perimeter. At the same time, the dust collection box adopts a quick positioning structure with snap-fit hooks and positioning springs, and is equipped with a horizontally sliding door panel. Operators only need to pull the snap-fit hooks to remove the collection box and open the door panel to empty the debris. The entire cleaning process does not require disassembling complex parts, greatly shortening maintenance time and reducing manual maintenance costs and labor intensity. Attached Figure Description

[0021] Please see Figure 1-4This utility model provides a technical solution: a packaging box logo embossing device. The core of this device is to simultaneously and efficiently clean and collect processing debris while accurately embossing the logo on the packaging box. Its overall structure is arranged in a layered layout around the main body 1. A support frame 2 is vertically welded upwards, using the top surface of the main body 1 as the installation reference. This support frame 2 is a rectangular steel frame structure. A logo embossing mechanism 3 is bolted to the bottom surface of its top beam. The embossing head of the logo embossing mechanism 3 is vertically positioned and can reciprocate up and down under the drive of a drive component (such as a cylinder or servo motor) to emboss the logo on the packaging box. The logo embossing mechanism 3 is located directly below... The top surface of the main body 1 of the equipment is horizontally milled and then fixed with a packaging box support platform 4 by bolts. The surface of the support platform has a positioning groove that matches the shape of the packaging box to ensure that the packaging box does not shift during the printing process. Near the top edge of the main body 1 of the equipment, an operation control panel 5 is fixed with a buckle. The operation control panel 5 is electrically connected to the drive components of the logo printing mechanism 3 and the cleaning component, and can realize the setting and control of parameters such as printing pressure, printing time and the start and stop of the cleaning component. In order to facilitate the maintenance of the logo printing mechanism 3 on the top of the support frame 2, a maintenance ladder 6 is welded and fixed vertically on one side wall of the support frame 2. The surface of the ladder steps is treated with anti-slip texture to ensure the safety of the operators.
[0022] On the top surface of the main body 1, and on one side of the packaging box support platform 4, a cleaning assembly for cleaning embossed debris is installed. The core component of the cleaning assembly is a debris adsorption panel 7, which is made of stainless steel. Several suction heads are drilled in a matrix array on the side of the panel facing the packaging box support platform 4. The suction heads are connected to the cavities inside the panel. One end of the debris adsorption panel 7 is rotatably connected to the top surface of the main body 1 via a hinge. The hinge axis is set in the horizontal direction, allowing the debris adsorption panel 7 to rotate around the hinge axis towards the packaging box support platform 4. The distance between the suction head and the debris generation area can be adjusted, and it can also be flipped to a horizontal state away from the support platform for easy cleaning of the support platform or replacement of packaging box specifications. On the middle of the panel away from the hinge of the debris adsorption panel 7, a dust conveying hose 8 (made of wear-resistant PVC material, with an inner diameter that matches the total flow area of the suction head) is fixedly connected by a hose clamp. A through hole is opened on the top surface of the main body 1 corresponding to the position of the dust conveying hose 8, and the end of the dust conveying hose 8 away from the debris adsorption panel 7 is inserted into the through hole and sealed by a sealing ring to prevent dust leakage.
[0023] On the lower surface of the main body 1, a rectangular placement plate is welded and fixed horizontally. The surface of the placement plate is positioned directly below the through hole of the main body 1. A collection device for collecting debris is placed on the plate. The core of the collection device is a dust collection box 14 (made of cold-rolled steel plate and rust-proofed inside). The top wall of the dust collection box 14 is provided with a hose connection port 19 that is compatible with the dust conveying hose 8, corresponding to the position of the through hole of the main body 1. One end of the dust conveying hose 8 passes through the through hole of the main body 1 and is inserted into the hose connection port 19. It is also sealed by a sealing ring to form a complete debris conveying channel of "dust suction head - panel cavity - conveying hose - collection box".
[0024] To ensure the debris adsorption panel 7 maintains a stable angle during operation and prevents positional shift due to vibration, a positioning structure is provided. A positioning block 9 is vertically welded to the side of the panel 7 furthest from the suction head and near the edge (the edge furthest from the hinge). Corresponding to the positioning block 9, a mounting base 12 is vertically welded to the top surface of the equipment body 1. The mounting base 12 has an "L"-shaped longitudinal section; its horizontal section is bolted to the surface of the equipment body 1, and its vertical section, facing the positioning block 9, is rotatably connected to a latching plate 11 via a rotating shaft. One end of the latching plate 11 engages with the rotating shaft, while the other end can move in an arc around the shaft axis. When the debris adsorption panel 7 is rotated to the working angle, the latching plate 11 rotates to abut against the top surface of the positioning block 9, thereby restricting the debris adsorption surface. As plate 7 continues to rotate, to ensure that the snap-on plate 11 remains in contact with the positioning block 9, a reset pressure spring 13 is welded and fixed between the side of the snap-on plate 11 away from the positioning block 9 and the inner wall of the vertical section of the fixed mounting base 12. This reset pressure spring 13 is in a pre-compressed state during assembly, constantly applying a spring force towards the positioning block 9 to the snap-on plate 11, driving the snap-on plate 11 to press tightly against the top surface of the positioning block 9, thus positioning the debris adsorption panel 7. When the angle of the debris adsorption panel 7 needs to be adjusted, the operator only needs to move the snap-on plate 11 away from the positioning block 9 to overcome the spring force of the reset pressure spring 13, allowing the snap-on plate 11 to disengage from the positioning block 9 and freely rotate the panel. After adjustment, the snap-on plate 11 is released, and under the action of the reset pressure spring 13, the snap-on plate 11 automatically resets and re-engages with the positioning block 9, making the operation convenient and efficient.
[0025] To facilitate quick disassembly and debris removal from the dust collection box 14, a rectangular guide groove (its dimensions are adapted to the cross-section of the box) is provided in the middle of one side wall of the dust collection box 14. The inner wall of the guide groove is milled horizontally. The movable door plate 18 (made of transparent acrylic or steel plate, with a clearance fit to the guide groove) is inserted into the guide groove and can slide left and right horizontally. When the movable door plate 18 is fully inserted into the guide groove, the guide groove is closed, and the collection box is sealed to prevent debris leakage. When debris needs to be removed, the movable door plate 18 is pulled outwards to open the guide groove, allowing the debris to be poured out. After cleaning, the movable plate is pushed back to its original position without disassembling the entire collection box. To prevent displacement of the dust collection box 14 during equipment operation (e.g., due to equipment vibration causing the collection box to deviate from directly below the through hole, resulting in hose detachment or dust leakage), a sliding sleeve is welded and fixed to the top of the side wall of the dust collection box 14 away from the movable door plate 18. The inner wall of the sleeve 16 (made of seamless steel pipe with the axis set horizontally) is slidably fitted with a snap-fit hook 15. A positioning spring 17 is welded and fixed between the outer surface of the snap-fit hook 15 away from the hook and the end of the sleeve 16. The positioning spring 17 is in a pre-stretched state during assembly and always applies a spring force towards the equipment body 1 to the snap-fit hook 15. A limiting groove adapted to the hook is opened on the surface of the placement plate below the equipment body 1 corresponding to the snap-fit hook 15. When the dust collection box 14 is placed on the placement plate and aligned, the hook end of the snap-fit hook 15 will automatically insert into the limiting groove under the spring force of the positioning spring 17, thereby fixing the collection box on the placement plate. When it is necessary to remove the collection box, simply pull the snap-fit hook 15 away from the equipment body 1 to overcome the spring force of the positioning spring 17 and disengage the hook from the limiting groove, and the collection box can be removed from the placement plate. The operation is simple and quick, greatly reducing the difficulty of maintenance.
[0026] Workflow
[0027] The operator sets the printing pressure (based on the packaging box material) and printing time of the logo printing mechanism 3 through the operation control panel 5, and checks whether the printing head of the logo printing mechanism 3 is intact through the maintenance ladder 6. Then, the operator moves the buckle plate 11 away from the positioning block 9, flips the debris adsorption panel 7 to the working angle, releases the buckle plate 11, and under the action of the reset pressure spring 13, the buckle plate 11 abuts against the positioning block 9 to complete the panel positioning. The packaging box to be printed with the logo is placed into the positioning groove of the packaging box carrier platform 4 to ensure that the printing position of the packaging box is aligned with the printing head of the logo printing mechanism 3.
[0028] The equipment is started by operating the control panel 5. The printing head of the logo printing mechanism 3 moves vertically downward under the drive of the drive component, contacts the surface of the packaging box and applies a set pressure. After holding for a set time, the logo printing is completed. Then the printing head returns to its vertical position. During the printing process, the control panel 5 simultaneously starts the negative pressure fan of the cleaning component (integrated inside the main body 1 of the equipment and connected to the cavity of the debris adsorption panel 7). The negative pressure generated by the negative pressure fan sucks the paper or plastic debris generated during printing into the cavity of the panel through the dust suction head on the debris adsorption panel 7. Then, it is transported to the dust collection box 14 through the dust conveying hose 8 to achieve synchronous cleaning of debris and prevent debris from accumulating on the support table or the surface of the printing head, which would affect the subsequent printing accuracy.
[0029] After the equipment has been working continuously for a certain period of time, the operator can turn off the equipment through the control panel 5, pull the snap hook 15 away from the main body 1 of the equipment to disengage the hook from the limiting groove of the placement plate, remove the dust collection box 14 from the placement plate, then pull the movable door plate 18 outward to open the guide groove and empty the debris inside the box. After cleaning, push the movable plate back to its original position, put the collection box back on the placement plate and align it, release the snap hook 15, and the hook will be inserted into the limiting groove under the action of the positioning and fixing spring 17 to complete the fixation. If it is necessary to clean the packaging box carrier platform 4, the snap plate 11 can be moved again to flip the debris adsorption panel 7 to a horizontal state, and the surface of the carrier platform can be wiped and cleaned directly. After cleaning, the panel can be reset. This embodiment, by clarifying the spatial position relationship and motion logic of each component, not only ensures the accuracy and stability of the logo imprinting on the packaging box, but also realizes real-time cleaning and convenient collection of debris through the coordinated work of the cleaning component and the collection device, effectively reducing the difficulty of equipment maintenance and improving the overall processing efficiency.
