Description

Technical Field

[0001] The present application relates to the field of paper box processing equipment, and in particular to a paperboard digital slotting machine with negative pressure adsorption and pressurized fixation. Background Art

[0002] In the molding process of paper boxes, the slotting process is a crucial link, which directly determines the processing quality of the folding lines and connecting parts of the cardboard, and further affects the three-dimensional molding effect of the paper box. At present, the existing cardboard slotting machines can achieve high precision and efficiency in large-scale production. However, for small batches or proofing processing, the existing technology has obvious shortcomings. Small batches or proofing processing usually adopt manual slotting. Although this method is flexible, it is difficult to guarantee accuracy and the efficiency is low. Due to the uncontrollability of manual operation, the physical products produced often have large deviations in dimensional accuracy and shape consistency, which is difficult to meet the market and customer requirements for high-quality products.

[0003] The main reasons for these shortcomings are as follows: First, manual slotting relies on the experience and skills of the operator, and the technical level of different operators varies greatly, resulting in inconsistent processing results. Second, manual operation is difficult to achieve positioning and control, especially when processing cardboard with complex shapes or high precision requirements, errors are more likely to accumulate. In addition, manual slotting is inefficient and difficult to meet the needs of rapid proofing or small batch production, especially in today's increasingly competitive market, customers have higher and higher requirements for delivery time, and the limitations of manual operation are more prominent.

[0004] In view of these shortcomings, developing a new type of cardboard slotting machine is of great significance and value. Summary of the invention

[0005] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a digital cardboard slotting machine with negative pressure adsorption and pressurized fixation. The device realizes double-layer fixation through negative pressure adsorption and synchronous pressing components, and cooperates with a linear motion mechanism to achieve high-precision and high-efficiency slotting processing of cardboard, which is particularly suitable for small batch or proofing production scenarios.

[0006] To achieve the above-mentioned purpose, the present application discloses a cardboard digital slotting machine with negative pressure adsorption and pressurized fixation, the digital slotting machine includes a negative pressure adsorption platform, a walking and pressing mechanism, a tool assembly and a controller, wherein the negative pressure adsorption platform includes a horizontally arranged working plane for carrying the cardboard to be processed; the walking and pressing mechanism is located on the negative pressure adsorption platform, including a longitudinal linear assembly, a transverse linear assembly and a pressing assembly, the walking and pressing mechanism is controlled by the controller to perform horizontal two-way movement to drive the tool assembly to complete slotting; the pressing assembly is located below the transverse linear assembly, and is used to press the cardboard during the slotting process.

[0007] At least one support block or support strip is fixedly provided on one side of the working plane near the edge. The support block or support strip is perpendicular to the working plane, and at least one side surface thereof forms a right angle with the working plane, so as to define the reference position of the paperboard and ensure the accurate positioning of the paperboard during the processing.

[0008] The working plane is provided with a plurality of suction holes penetrating the working plane, the suction holes are connected with a cavity arranged inside the negative pressure adsorption platform, the cavity is a closed space, and is connected with a negative pressure pipe or equipment through a connecting pipe.

The two travel positions are smoothly connected by a transitional travel to achieve smooth movement of the pressing plate. In the horizontal linear assembly, a guide column is installed on the horizontal motion slide or the tool support to match the slide plate. The guide column is inserted into the slide groove of the slide plate and forms a sliding fit with the slide groove. When the horizontal motion slide performs horizontal movement, the guide column first moves along the slide groove, pushes the slide groove plate to drive the pressing plate to move downward, and completes the pressing of the cardboard.

[0014] The lower part of the slide plate cooperates with the pressure plate through a guide pin with a pressure spring. One end of the guide pin is vertically inserted into the slide plate, and the other end is connected to the pressure plate.

Preferably, one end of the transverse guide rail in the transverse linear assembly is connected to the longitudinal motion slide, and the other end is slidably connected to the auxiliary guide rail through a slider, so that the smooth movement of the transverse linear assembly is achieved under the joint support of the longitudinal linear assembly and the auxiliary guide rail.

The lateral lead screw is threaded with the lateral motion slide to drive the lateral motion slide to move linearly along the lateral guide rail.

[0019] As an optional technical solution, the longitudinal drive motor and the transverse drive motor are connected to the longitudinal motion slide and the transverse motion slide via a synchronous belt, and the linear motion is achieved by the transmission of the synchronous belt.

[0020] As an optional technical solution, the longitudinal linear component and the transverse linear component are directly driven by a linear motor without the need for a lead screw or a synchronous belt, and have higher movement speed and precision.

[0035] Refer to the attached Figures 1 to 3This embodiment discloses an exemplary structure of a cardboard digital slotting machine with negative pressure adsorption and pressurized fixation. The digital slotting machine includes a negative pressure adsorption platform 1, a walking and pressing component 2 and a tool component 3. The structural design and coordinated work of each component realize high-precision slotting processing of the cardboard.

[0036] The negative pressure adsorption platform 1 is made of high-strength aluminum alloy or stainless steel or marble. Its horizontally arranged working plane 4 is ground and surface-treated to ensure that the upper surface has good flatness (flatness error ≤ 0.1mm) for carrying the paperboard to be processed. At least one support bar 5 is fixedly arranged near the edge of one side of the working plane 4. The support bar 5 is made of hard material (such as hardened steel or engineering plastic). Its inner surface forms a right angle (90°±0.1°) with the working plane 4, which is used to define the reference position of the paperboard and ensure the accurate positioning of the paperboard during the processing.

[0037] There are multiple suction holes 6 evenly distributed on the working plane 4, which penetrate the working plane 4. The diameter of the suction holes 6 is 2-5 mm, and the hole spacing is 10-20 mm. The suction holes 6 are connected to the cavity (not shown in the figure) set inside the negative pressure adsorption platform 1. The cavity is a closed space, which is connected to an external negative pressure device (such as a vacuum pump or a blower) through a connecting pipe. When the negative pressure device is started, a negative pressure (usually -0.1 to -0.3MPa) is formed in the cavity, and the cardboard is stably adsorbed on the working plane 4 through the suction holes 6 to prevent the cardboard from displacement or deformation during processing. The specific size of the negative pressure adsorption platform 1 and the distribution of the suction holes 6 can be adjusted according to actual processing requirements. Such design belongs to the well-known technology of those skilled in the art and does not need to be further explained in detail.

[0038] The walking and pressing assembly 2 is installed on the negative pressure adsorption platform 1, and includes a longitudinal linear assembly 7, a transverse linear assembly 8 and a pressing assembly 9. The longitudinal linear assembly 7 is arranged horizontally and longitudinally, and includes a longitudinal guide rail, a longitudinal drive motor and a longitudinal motion slide that can slide along the longitudinal guide rail. The longitudinal guide rail is a linear guide rail (such as a ball linear guide rail), which is fixed to a side of the negative pressure adsorption platform 1 near the edge through a bracket. The longitudinal drive motor is a servo motor or a stepper motor, which is connected to the longitudinal lead screw through a coupling. The longitudinal lead screw is threaded with the longitudinal motion slide to drive the longitudinal motion slide to perform stable linear motion along the longitudinal guide rail. The lead and precision of the longitudinal lead screw can be selected according to the processing requirements. The specific parameters and selection of this type of drive method belong to the prior art and need not be elaborated.

[0039] The auxiliary guide rail 10 is arranged parallel to the longitudinal linear component 7 and fixed to a position near the edge of the other side of the negative pressure adsorption platform 1, and is used to assist the sliding of the transverse linear component 8 to ensure the stability and accuracy of the transverse linear component 8 during the movement. The specific structure and installation method of the auxiliary guide rail 10 belong to the conventional design of those skilled in the art and do not need to be further described in detail.

[0040] The transverse linear component 8 is horizontally placed and fixedly mounted on the longitudinal motion slide, and includes a transverse guide rail, a transverse drive motor, and a transverse motion slide that can slide along the transverse guide rail. The transverse guide rail is a linear guide rail (such as a ball linear guide) fixed to the longitudinal motion slide. The transverse drive motor is a servo motor or a stepper motor, which is connected to the transverse lead screw through a coupling, and the transverse lead screw is threaded with the transverse motion slide to drive the transverse motion slide to perform precise linear motion along the transverse guide rail. One end of the transverse linear component 8 is connected to the longitudinal motion slide, and the other end is slidably connected to the auxiliary guide rail 10 through a slider, so that the smooth movement of the transverse linear component 8 is achieved under the joint support of the longitudinal linear component 7 and the auxiliary guide rail 10. The selection and installation method of the transverse lead screw and the slider belong to the well-known technology of those skilled in the art and do not need to be further explained in detail.

[0041] The material pressing component 9 is located below the horizontal linear component 8 and is connected to the horizontal guide rail through the vertical guide component 11. It is used to press the cardboard during the slotting process to prevent the cardboard from being displaced or deformed during the process. The material pressing component 9 includes a slide plate 12 and a pressure plate 13. The slide plate 12 is connected and matched with the horizontal linear component 8 through the vertical guide component 11, so that the slide plate 12 can perform reciprocating linear motion in the vertical direction. The slide plate 12 is arranged along the axial direction of the horizontal linear component 8, and a slide groove 14 is opened inside it. The slide groove 14 has at least two stroke positions, namely a high position for pressing the material and a low position for discharging the material. The two stroke positions are smoothly connected by a transition stroke to achieve smooth movement of the pressure plate 13.

[0042] The pressing plate 13 is located at the lower end of the chute plate 12, and its lower surface is in contact with the cardboard, and is used to apply pressure to fix the cardboard. The pressing plate 13 is made of hard material (such as hardened steel or engineering plastic), and its lower surface is ground to ensure the flatness and uniformity when in contact with the cardboard. The pressing plate 13 cooperates with the chute plate 12 through a guide pin 15 with a pressing spring. One end of the guide pin 15 is vertically inserted downward into the preset slot of the chute plate 12, and the other end is connected to the pressing plate 13. The pressing spring is sleeved on the guide pin 15 and is located between the chute plate 12 and the pressing plate 13. The main function of the pressing spring is to press the cardboard through its elastic force to ensure that the cardboard remains stable during processing. The elastic force of the spring can be adjusted according to the thickness and material of the cardboard to achieve the best pressing effect, thereby avoiding damage to the cardboard or affecting the processing accuracy due to excessive pressure.

[0043] A tool holder 16 is fixedly provided on the lateral motion slide, and the tool holder 16 is installed with the tool assembly 3 by a detachable connection method such as bolts or buckles. The tool holder 16 is made of high-strength material (such as aluminum alloy or steel), and its structural design ensures rigidity and stability. At least one adjustment bolt is provided on the tool holder 16, and the adjustment bolt is connected to the tool assembly 3, which is used to adjust the installation height of the tool assembly 3, so as to accurately control the slotting depth. The accuracy of the adjustment bolt is usually 0.1mm to meet the requirements of high-precision processing. The tool assembly 3 includes at least one slotting knife, which is made of high-speed steel or cemented carbide material, and its cutting edge is ground to ensure the accuracy and smoothness of the slotting. The slotting knife is fixed to the tool assembly 3 by bolts or a quick-change mechanism for easy replacement and maintenance. The specific structure and installation method of the tool assembly 3 belong to the conventional design of technicians in this field and do not need to be further described in detail.

[0044] In actual operation, the cardboard is first placed on the working plane 4 of the negative pressure adsorption platform 1 and accurately positioned by the support bar 5. After the negative pressure device is started, the cardboard is firmly adsorbed on the working plane 4. The longitudinal drive motor and the transverse drive motor drive the tool assembly 3 to move independently or synchronously in the horizontal transverse and horizontal longitudinal directions according to the preset slotting path to complete the slotting process of the cardboard. The spacing between the tool assembly 3 and the working plane 4 is adjusted by adjusting the bolt to ensure accurate control of the slotting depth. At the same time, the pressing assembly 9 presses the cardboard during the processing to ensure that the cardboard does not move or deform during the processing.

[0045] In addition, the walking press component 2 can also adopt other driving forms, such as synchronous belt drive, linear motor drive or gear rack drive. In the synchronous belt drive form, the longitudinal drive motor and the transverse drive motor are connected with the longitudinal motion slide and the transverse motion slide by a synchronous belt, and the transmission of the synchronous belt is used to realize accurate linear motion. In the linear motor drive form, the longitudinal linear component 7 and the transverse linear component 8 are directly driven by a linear motor, without the need for a lead screw or a synchronous belt, and have higher movement speed and precision. In the gear rack drive form, the longitudinal drive motor and the transverse drive motor are engaged with the gear rack to drive the longitudinal motion slide and the transverse motion slide to perform linear motion. The specific implementation of these drive forms belongs to the known technology of those skilled in the art and does not need to be further described in detail.

[0046] It should also be understood that the control of the transverse drive motor and the longitudinal drive motor is completed by a controller (not shown in the figure), which can be an independent controller or a controller integrated in a large production line.

[0047] In this embodiment, the controller serves as the core control unit of the cardboard digital slotting machine. Its structural design is highly integrated and fully functional. It is mainly composed of an input interface, a central processing unit (usually a CPU), a parsing module and a motion control module. The modules communicate and work together through a high-speed data bus.

[0048] The input interface is a key part of the controller's interaction with external devices or operators. It supports multiple input methods, including USB interface, Ethernet interface, and RS-232 serial communication interface. It can receive digital instructions from operators' manual input or from the host computer. These instructions are usually input in the form of standardized G code, DXF file or other CNC programming language to ensure compatibility with general industry software. The central processing unit uses a high-performance multi-core processor with powerful data processing and real-time response capabilities. It is responsible for decoding, checking and logical processing of input digital instructions to ensure the accuracy and integrity of the instructions. At the same time, it coordinates the workflow of the analysis module, motion control module and other auxiliary modules to achieve multi-task parallel processing.

[0049] The analysis module is the core computing unit of the controller. It usually has an algorithm library embedded inside, which can convert the input digital instructions into specific motion control parameters, including the coordinate position, movement speed, acceleration, and deceleration of the tool assembly in the horizontal (X-axis) and vertical (Y-axis) directions. The analysis module also supports dynamic path planning function, which can automatically optimize the tool's motion trajectory according to processing requirements, reduce idle travel time, and improve processing efficiency.

[0050] The motion control module is the execution unit of the controller, which integrates the motion control algorithm and the pulse signal generator. It can generate corresponding control signals according to the parameters output by the analytical module, and control the operation of the stepper motor or servo motor through the motor driver to achieve precise control of the walking and pressing mechanism 2. The stepper motor or servo motor is connected to the linear component (such as a ball screw or a synchronous belt drive system) of the walking and pressing mechanism through a high-rigidity coupling, and drives the slider to move along the precision linear guide rail, thereby achieving precise positioning and movement of the tool assembly on the cardboard.

[0051] More specifically, the motion control module also has a real-time feedback function, which monitors the position and speed of the walking and pressing mechanism in real time through a high-resolution encoder or grating ruler, and transmits the feedback signal to the central processing unit to form a closed-loop control to ensure processing accuracy and stability. In addition, in actual applications, the controller can also be equipped with multiple safety protection mechanisms, including overload protection, overheating protection, limit switch protection, and emergency stop function. When an abnormal situation occurs during the operation of the equipment (such as motor overload, tool damage, or position exceeding the limit), the controller can promptly issue an audible and visual alarm signal and stop the operation of the equipment, and record the fault information in the internal memory for subsequent analysis and maintenance.

[0052] The structure, control principle and control process of the controller are well-known and known technologies to those skilled in the art and belong to the prior art, so no further detailed description is required.

[0053] In the embodiments, all the directions described are defined with reference to the accompanying drawings. For example, the horizontal longitudinal direction of the longitudinal linear component 7, the horizontal transverse direction of the transverse linear component 8, and the parallel setting direction of the auxiliary guide rail 10 are all based on the specific orientations shown in the accompanying drawings. This way of describing directions based on the accompanying drawings can clearly and accurately express the relative position relationship and movement direction between the components, which is convenient for those skilled in the art to understand and implement. As an important part of the embodiments, the accompanying drawings provide an intuitive spatial reference to ensure the accuracy and consistency of the description of the embodiments. For directions or positions not clearly marked in the drawings, those skilled in the art can make reasonable inferences based on conventional technical knowledge and the contextual information provided by the drawings. Such inferences belong to the common knowledge of those skilled in the art and do not require further detailed explanation.

[0054] Compared with manual slotting, the cardboard digital slotting machine has significant advantages in slotting accuracy, processing efficiency and product consistency. Manual slotting relies on the experience and skills of the operator, and its slotting accuracy is usually difficult to guarantee, with a large error range (usually above ±1mm), and the difference in technical level between different operators will lead to inconsistency in processing results, especially when dealing with cardboard with complex shapes or high precision requirements, errors are more likely to accumulate. In addition, manual slotting is inefficient and difficult to meet the needs of fast delivery, especially in small batches or proofing processing, the limitations of manual operation are more prominent. In contrast, the digital slotting machine can achieve slotting accuracy error control within ±0.1mm through the synergy of the negative pressure adsorption platform 1 and the linear motion mechanism, significantly improving the processing accuracy. At the same time, automated operation reduces human intervention, ensures the consistency of product size and shape, and avoids quality fluctuations caused by differences in operator technical levels.

[0055] In small-batch processing scenarios, the device can quickly respond to order requirements and achieve flexible production. For example, in paper box proofing, manual slotting usually requires a long preparation and processing time, while the digital slotting machine can complete high-precision slotting tasks in a short time, significantly shortening the production cycle and meeting customers' needs for fast delivery. In addition, through digital control, the device can accurately slot according to preset patterns or sizes to meet the personalized needs of different orders, without the need to frequently adjust equipment or change tools, further improving production flexibility and efficiency. For small batch orders, this quick response and flexible production capability is particularly important, which can help companies gain an advantage in the fierce market competition.

[0056] The cardboard digital slotting machine realizes high-precision and high-efficiency slotting processing of cardboard through the synergistic effect of the negative pressure adsorption platform 1, the material pressing component 9 and the linear motion mechanism, which is particularly suitable for small batch or proofing production scenarios. In practical applications, the equipment can significantly improve processing accuracy and efficiency, reduce manual intervention and material waste, reduce production costs, and meet the market and customer demand for high-quality products. For example, in the proofing of paper boxes, the equipment can complete high-precision slotting tasks in a short time, ensure the consistency of sample size and shape, and provide reliable technical support for subsequent large-scale production.

[0057] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence.
