Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box production and processing technology, specifically to an embossing device for corrugated cardboard box production. Background Technology

[0002] In the corrugated cardboard box production process, the creasing process is a crucial step that determines the quality of the box's formation and its subsequent performance. Precise creases must be pressed onto the surface of the corrugated cardboard using creasing equipment to ensure structural stability and dimensional compliance after folding. However, current traditional corrugated cardboard box creasing equipment still has many technical shortcomings in practical applications, making it difficult to meet diverse and efficient production needs. Specific problems are as follows:

[0003] Firstly, the equipment suffers from poor versatility, making it difficult to adapt to production of multiple specifications. Traditional creasing equipment often features fixed creasing spacing and groove structures. When producing corrugated boxes of different widths and with varying numbers of creases, the entire creasing module or groove assembly must be replaced. This not only involves a cumbersome disassembly and assembly process but also leads to production interruptions, significantly reducing operational efficiency. Especially in small-batch, multi-order production scenarios, frequent component replacements significantly increase time and labor costs, restricting the company's production flexibility.

[0004] Secondly, the core components are cumbersome to disassemble and assemble, resulting in low efficiency in operation switching. Traditional embossing equipment often uses bolts and other complex connectors to fix the embossing blades and grooving blocks. Changing between different specifications of embossing blades or grooving blocks requires specialized tools to disassemble and install them one by one, involving numerous steps and significant time consumption. In production scenarios with frequent changes in order specifications, excessively long component replacement times lead to increased equipment idle rates, making it difficult to meet the demands of efficient production, and also increasing the workload of operators.

[0005] Third, the adjustment structure has poor stability, and the crease position is prone to deviation. The crease groove assembly adjustment mechanism of traditional crease equipment mostly uses a simple slide rail and slider, which lacks a precise guiding and limiting structure. During the adjustment of the spacing or crease operation, the crease groove assembly is prone to deviation due to factors such as vibration and force, which makes it impossible for the crease knife and the crease groove block to be accurately aligned. This ultimately causes the crease position to deviate, affecting the subsequent folding and forming of the carton, and even leading to product scrap.

[0006] Based on the above problems, there is an urgent need to develop an indentation device with flexible adjustment, adaptive indentation, and quick assembly / disassembly to solve the above technical problems and meet the industry's production needs. Utility Model Content

[0007] The purpose of this utility model is to provide a creasing device for corrugated carton production, which solves the technical problem that traditional creasing devices are difficult to adapt to corrugated carton boards of different widths and folding requirements, and require frequent replacement of the entire component, resulting in low efficiency. It achieves the goal of quickly adapting to the production of cartons of multiple specifications and improving the equipment's versatility and operating efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a creasing device for corrugated cardboard box production, comprising a support plate, a centering adjustment creasing part, and a replaceable adjustment creasing groove part; support pads are symmetrically fixedly installed on the bottom outer wall of the support plate; the centering adjustment creasing part is disposed on the top of the support plate; and the replaceable adjustment creasing groove parts are respectively disposed between the support plate and the centering adjustment creasing part.

[0009] The centering adjustment indentation part specifically includes: a positioning sleeve, symmetrically fixedly installed on the top outer wall of the support plate; a support rod, symmetrically fixedly installed on the top outer wall of the support plate; and a support top plate, fixedly installed on the top of the support rod.

[0010] Preferably, a pneumatic telescopic rod is fixedly installed on the top outer wall of the supporting top plate. The telescopic end of the pneumatic telescopic rod movably penetrates the top outer wall of the supporting top plate and extends to the bottom outer wall of the supporting top plate. A fixing frame is fixedly installed on the telescopic end of the pneumatic telescopic rod. A lifting plate is fixedly installed at the bottom of the fixing frame. Rectangular guide grooves are symmetrically opened on the lifting plate. A movable passage is opened on the lifting plate. A slide rail is fixedly installed on the top outer wall of the lifting plate and inside the fixing frame. A positioning slide rod is fixedly installed inside the positioning sleeve. The lifting plate is movably sleeved on the outer wall of the positioning slide rod.

[0011] A lifting plate is installed, which is movably fitted onto the outer wall of the positioning slide rod. When the pneumatic telescopic rod drives the fixing frame and the lifting plate to rise and fall as a whole, the positioning slide rod provides stable guidance for the lifting plate, effectively preventing deviation or shaking during the lifting process and ensuring the accuracy of the indentation operation. The rectangular guide groove on the lifting plate slides in cooperation with the rectangular limiting slider on the top of the adjusting plate, which can limit the movement of the adjusting plate and ensure that the adjusting plate slides smoothly in the predetermined direction during the movement, improving the stability of the indentation position adjustment. At the same time, the moving passage on the lifting plate provides space for the movement of the rectangular block, making the moving slider drive the adjusting plate to move more smoothly through the rectangular block, ensuring the flexibility and reliability of the indentation spacing adjustment.

[0012] Preferably, a drive motor is fixedly installed on the outer wall of the slide rail. The output end of the drive motor movably passes through one side of the outer wall of the slide rail and extends into the interior of the slide rail.

A rectangular block is fixedly connected to the bottom outer wall of each movable slider.

[0013] Preferably, the rectangular block is slidably installed inside the movable opening, and an adjusting plate is fixedly installed on the bottom outer wall of each movable slider. Rectangular limiting sliders are symmetrically fixedly installed on the top outer wall of the adjusting plate. The rectangular limiting sliders are slidably installed inside the rectangular guide groove. Each rectangular limiting slider has a sliding hole, and a sliding rod is slidably installed inside each sliding hole. One end of the sliding rod movably passes through the top outer wall of the adjusting plate and extends to the bottom outer wall of the adjusting plate. An indentation mounting block is fixedly installed on one end of the sliding rod, and the other end of the sliding rod extends to the top outer wall of the rectangular limiting slider.

[0014] A creasing mounting block is provided, which is slidably connected to a rectangular limiting slider via a sliding rod. The springs fitted on the outer wall of the sliding rod connect the limiting plates at both ends to the rectangular limiting slider. During the creasing process, the springs provide elastic cushioning, preventing damage caused by excessive force when the creasing blade contacts the corrugated cardboard box, while ensuring uniform creasing force and improving creasing quality. The mounting groove on the creasing mounting block slides in conjunction with the sliding plate. Combined with the threaded holes on both sides of the creasing mounting block and the mounting through holes of the U-shaped mounting plate on the sliding plate, the sliding plate and the creasing blade at the bottom can be easily disassembled and replaced. This allows for easy switching of the appropriate creasing blade according to the creasing requirements of different corrugated cardboard boxes, enhancing the versatility and practicality of the equipment.

[0015] Preferably, a limiting plate is fixedly installed at the other end of the slide rod, and a spring is movably sleeved on the outer wall of the slide rod. The two ends of the spring are fixedly connected to the bottom outer wall of the limiting plate and the top outer wall of the rectangular limiting slider, respectively. Each indentation mounting block has an installation groove, and a sliding plate is slidably installed inside each installation groove. Threaded holes are opened on both outer walls of the indentation mounting block. A U-shaped mounting plate is fixedly installed at one end of each sliding plate.

[0017] Preferably, an I-shaped slider is symmetrically slidably installed inside the I-shaped groove. Each I-shaped slider is connected to a positive and negative lead screw by two threads. A support connecting rod is fixedly connected to the top outer wall of the I-shaped slider. The other end of the support connecting rod extends to the top of the adjusting base through a strip-shaped sliding opening. An adjusting base is fixedly connected to the other end of the support connecting rod. Guide blocks are symmetrically fixedly installed on the bottom outer wall of the adjusting base. The guide blocks are slidably installed inside the guide groove. The top outer wall of the adjusting base is provided with mounting positioning holes at equal intervals.

[0018] The system features mounting positioning holes. By determining the positioning relationship between these holes and the corresponding mating components, the installation position of the grooving block on the adjusting base can be quickly and accurately determined. This ensures the alignment accuracy between the grooving block and the indentation knife above, improving the accuracy of the indentation position. The guiding and positioning function of the mounting positioning holes simplifies the installation process of the grooving block, eliminating the need for repeated adjustments and improving efficiency when assembling or replacing the block. Combined with the magnetic attraction of the magnetic block, the mounting positioning holes provide a stable mounting foundation for the grooving block, preventing displacement or shaking due to force during operation and ensuring the stability of the indentation operation. The standardized mounting positioning holes facilitate compatibility with different models of grooving blocks of the same size, increasing the equipment's adaptability to various indentation needs and enhancing its versatility and flexibility.

[0037] Example 2:

[0038] Based on Embodiment 1, a preferred embodiment of the creasing equipment for corrugated cardboard box production provided by this utility model is as follows: Figure 1-4 As shown: The replaceable adjustable pressure groove part 4 specifically includes: an adjusting base 411, which is fixedly installed on the top outer wall of the supporting plate 1; a motor 414 is fixedly installed on the outer wall of the adjusting base 411; an I-shaped slide groove 412 is opened inside the adjusting base 411; guide grooves are symmetrically opened on the top outer wall of the adjusting base 411; strip-shaped slide openings 413 are symmetrically opened on the top outer wall of the adjusting base 411, and the strip-shaped slide openings 413 are all connected to the I-shaped slide groove 412; a positive and negative lead screw 415 is fixedly connected to the output end of the motor 414; baffles are fixedly installed on both sides of the outer wall of the adjusting base 411; and the other end of the positive and negative lead screw 415 is rotatably connected to the outer wall of the baffle.

[0039] The I-shaped slide groove 412 is symmetrically and slidably installed with I-shaped sliders 416. The I-shaped sliders 416 are all threadedly connected to the positive and negative lead screws 415. The top outer wall of the I-shaped sliders 416 is fixedly connected with a support connecting rod. The other end of the support connecting rod extends to the top of the adjusting base 411 through the strip-shaped slide 413. The other end of the support connecting rod is fixedly connected to the adjusting base 417. The bottom outer wall of the adjusting base 417 is symmetrically fixedly installed with guide blocks. The guide blocks are slidably installed inside the guide groove. The top outer wall of the adjusting base 417 is provided with mounting positioning holes at equal intervals.

[0040] Magnetic blocks 418 are fixedly installed inside the mounting positioning holes. The top outer wall of the adjusting base 417 is provided with a pressure groove block 4111. Magnetic blocks 419 are fixedly installed at equal intervals on the bottom outer wall of the pressure groove block 4111. Magnetic blocks 418 and 419 attract each other. A placement plate is fixedly installed on the top outer wall of the adjusting base 411. Rectangular adjustment openings are symmetrically opened on the placement plate. The adjusting bases 417 are respectively set inside the rectangular adjustment openings.

[0041] Furthermore, in this embodiment, the motor 414 of the replaceable adjustable groove section 4 is activated. The motor 414 drives the positive and negative lead screws 415 to rotate, causing the I-shaped sliders 416 to slide synchronously in opposite directions within the I-shaped groove 412. The I-shaped sliders 416 move the adjusting bases 417 along the guide groove via the support connecting rod and the strip-shaped sliding opening 413 until the distance between the two adjusting bases 417 matches the crease requirements of the carton. The corresponding groove block 4111 is selected according to the creasing specifications.

This design can easily adapt to corrugated cardboard of different widths and different folding requirements without replacing the entire groove assembly, improving the adaptability of the equipment to diverse production tasks. The groove block is fixed by the magnetic block and the mounting positioning hole on the adjusting base. No complicated tools are needed for disassembly and assembly; it can be replaced simply by adsorption or removal. This design significantly reduces the switching time between different sizes of grooved blocks, minimizes production interruptions, and improves overall operational efficiency.

[0042] Working principle:

[0043] Step 1: Adjust the position of the creasing groove and creasing components according to the carton specifications.

[0044] Adjusting the groove spacing: Start the motor 414 of the replaceable adjustable groove part 4. The motor 414 drives the positive and negative lead screws 415 to rotate, which drives the I-shaped sliders 416 to slide synchronously in opposite directions within the I-shaped slide groove 412. The I-shaped sliders 416 drive the adjusting bases 417 to move along the guide groove through the strip-shaped slide opening 413 via the support connecting rod until the distance between the two adjusting bases 417 matches the crease requirements of the carton.

[0045] Install the pressure block: Select the corresponding pressure block 4111 according to the pressure mark specifications, and fix it by magnetic attraction block 418 in the positioning hole on the adjustment base 417 through bottom magnetic attraction block 2 419 to ensure accurate positioning of pressure block 4111.

[0046] Adjusting the spacing of the indentation cutters: Start the drive motor 318 of the centering and adjusting indentation section 3. The drive motor 318 drives the positive and negative lead screws 319 to rotate, so that the moving slider 3112 moves synchronously within the slide rail 317. The moving slider 3112 drives the indentation cutters 3117 to adjust the spacing through the rectangular block and the adjusting plate, so that it corresponds to the position of the lower grooving block 4111. The rectangular limit slider 3113 slides along the rectangular guide groove to ensure stable adjustment.

[0047] Step 2: Place the corrugated cardboard to be processed. Place the corrugated cardboard on the placement plate on top of the adjustment base 411, aligning the edges of the cardboard with the equipment reference. The rectangular adjustment opening of the placement plate is reserved for the pressure block 4111 to avoid interfering with the positioning of the cardboard.

[0048] Step 3: Perform the indentation operation

[0049] Creasing knife descent: Activate the pneumatic telescopic rod 315, whose telescopic end pushes the fixed frame 316 and the lifting plate to move downward along the positioning slide rod 313, causing the crease knife 3117 to approach the cardboard.

[0050] Adaptive Creasing: When the crease knife 3117 contacts the cardboard, the slide bar slides along the sliding hole of the rectangular limit slider 3113, the spring 3115 is compressed and provides cushioning, and the crease force is automatically adjusted according to the thickness and hardness of the cardboard to ensure clear creases without damaging the cardboard.

[0051] Creasing fit: The crease knife 3117 and the lower crease block 4111 work precisely to press the corresponding crease on the cardboard surface. The positioning slide bar 313 ensures that the lifting plate moves vertically and avoids crease deviation.

[0052] Step 4: Resetting and Material Removal

[0053] Indentation tool reset: After indentation is completed, the pneumatic telescopic rod 315 retracts, driving the indentation tool 3117 to rise. The spring 3115 rebounds, causing the indentation tool 3117 to return to its initial position.

[0054] Material removal and specification change: Remove the creased cardboard. If a specification change is required, repeat step one to adjust the spacing or replace the creasing block 4111 and the creasing knife 3117. The sliding plate 3116 cooperates with the mounting groove, and the threaded hole and mounting through hole are used for quick disassembly and assembly, so that the next batch of work can be carried out.

[0055] Through the above steps, the equipment achieves precise and efficient creasing of corrugated boxes of different specifications, while also offering both adjustment flexibility and operational stability.

[0056] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
