Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard box manufacturing equipment, and specifically discloses a gluing machine for corrugated paper production that is easy to adjust. Background Technology

[0002] The corrugated cardboard gluing machine is a key piece of equipment in the carton forming production line. Its operational stability and ease of adjustment are directly related to production efficiency and product qualification rate.

[0003] Chinese utility model patent authorization announcement number CN207373792U discloses an easily adjustable gluing machine, which achieves static adjustment of the machine body's level by manually rotating an adjusting nut to drive a threaded rod, and is equipped with a baffle that can slide along the guide rail for guidance. While this solution provides some adjustment functionality, it still has significant shortcomings in practical applications:

[0004] First, its leveling relies on initial manual settings, which is a static leveling process. It cannot detect or compensate for horizontal drift caused by equipment vibration or ground settlement during production, leading to gradual instability of the equipment during long-term operation and affecting the consistency of bonding quality.

[0005] Secondly, the guide baffle adjustment lacks a feedback mechanism, and the clamping force depends entirely on the operator's experience and judgment, making it difficult to control precisely. If it is too loose, the carton may deviate from its original position, or if it is too tight, the corrugated cardboard may be crushed and deformed.

[0006] Therefore, there is an urgent need for a gluing machine that can achieve dynamic automatic leveling and has intelligent guiding function with force control feedback, so as to improve the automation level, operational stability and product quality of the equipment. Utility Model Content

[0007] This utility model proposes a carton gluing machine for corrugated paper production that is easy to adjust. Through dynamic automatic leveling, precise force control guidance, and adaptive pressing, it achieves long-term stable operation of the equipment, accurate carton positioning and pressing, and improved production automation. At the same time, it extends the equipment's lifespan, comprehensively solves the defects of existing technologies, and balances production efficiency and product quality.

[0008] This invention is implemented as follows: a carton gluing machine for corrugated paper production that is easy to adjust includes a frame and a conveying mechanism mounted on the frame, as well as an adaptive leveling system, an automatic positioning and guiding mechanism, and a gluing and pressing mechanism. The adaptive leveling system is located at the bottom of the frame and is used to monitor and automatically maintain the horizontal state of the frame in real time. The automatic positioning and guiding mechanism is located on the frame and on both sides of the conveying path, and is used to center the cartons and detect the clamping force. The gluing and pressing mechanism is mounted across the frame and is used to apply glue and press the cartons together.

[0009] The adaptive leveling system includes a level sensor, a control unit, multiple electrically operated leveling legs located at the bottom corners of the frame, and a driver for driving the legs. The level sensor is signal-connected to the control unit, and the control unit is control-connected to the driver.

[0010] As a preferred embodiment of the easily adjustable corrugated paper gluing machine of this utility model, the automatic positioning and guiding mechanism includes two sets of symmetrically arranged guiding components. Each set of guiding components includes a linear drive module fixed on the frame, a guide plate driven to translate by the linear drive module, and a first pressure sensor disposed on the guide plate for detecting the pressure between the guide plate and the side of the carton.

[0011] As a preferred embodiment of the adjustable corrugated paper gluing machine of this utility model, the glue coating and pressing mechanism includes a gantry frame, a glue storage tank installed on the gantry frame, a glue coating head connected to the glue storage tank through a pipe, a pressing component located downstream of the glue coating head, and an electric lifting device for driving the pressing component to rise and fall vertically.

[0012] As a preferred embodiment of the adjustable corrugated paper gluing machine of this utility model, the pressing assembly includes a mounting plate connected to the output end of the electric lifting device, a pressing roller rotatably connected to the mounting plate via a bearing, and a second pressure sensor disposed between the mounting plate and the electric lifting device for monitoring the pressing force.

[0013] As a preferred embodiment of this utility model of a corrugated paper gluing machine for easy adjustment, the linear drive module is a servo electric slide table or a ball screw slide table.

[0014] As a preferred embodiment of this utility model of a corrugated paper gluing machine for easy adjustment, the control unit is a PLC or a microcontroller. The control unit has a preset horizontal tolerance range. When the detection data of the horizontal sensor exceeds this range, the control unit can automatically adjust the height of the corresponding electric leveling support.

[0015] As a preferred embodiment of this utility model of a corrugated paper gluing machine for easy adjustment, the bottom of the electric leveling support is provided with a shock-absorbing pad, the material of which is rubber or polyurethane.

[0016] The beneficial effects of this utility model are:

[0017] 1. By linking the "level sensor, control unit, and electric leveling feet" of the adaptive leveling system, dynamic level compensation is achieved during equipment operation, solving the problem that the existing static leveling technology cannot cope with instability caused by vibration and settlement, ensuring consistent bonding quality, and reducing the scrap rate caused by equipment instability.

[0018] 2. The clamping force is fed back in real time by the first pressure sensor of the automatic positioning and guiding mechanism, avoiding the error of human experience judgment, preventing the carton from running off-center or being crushed and deformed, and improving the qualification rate of corrugated cardboard forming.

[0019] 3. By cooperating with the electric lifting device and the second pressure sensor of the glue-applying and pressing mechanism, the pressing force is dynamically adjusted to adapt to the pressing needs of corrugated cardboard of different thicknesses, such as single-wall and double-wall, eliminating the need for frequent manual adjustment of the pressing height and improving the equipment's versatility. Furthermore, the equipment achieves automated control of leveling, guiding, and pressing, reducing operator intervention steps, lowering labor intensity, and improving production efficiency. Simultaneously, the shock-absorbing pads at the bottom of the electric leveling feet absorb vibrations, reducing wear on equipment components. The high-precision linear drive module reduces mechanical wear on the guiding mechanism, extending the overall service life of the equipment. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-3A carton gluing machine for corrugated paper production that is easy to adjust includes a frame 1 and a conveying mechanism 2 disposed on the frame 1. It also includes an adaptive leveling system 3, an automatic positioning and guiding mechanism 4, and a gluing and pressing mechanism 5. The adaptive leveling system 3 is disposed at the bottom of the frame 1 and is used to monitor and automatically maintain the horizontal state of the frame 1 in real time. The automatic positioning and guiding mechanism 4 is disposed on the frame 1 and located on both sides of the conveying path, and is used to center the carton and detect the clamping force. The gluing and pressing mechanism 5 is disposed across the frame 1 and is used to apply glue and press the carton.

[0027] The adaptive leveling system 3 includes a level sensor 6, a control unit 7, multiple electrically operated leveling feet 8 located at the bottom corners of the frame 1, and drivers 9 that drive the feet. The level sensor 6 is signal-connected to the control unit 7, and the control unit 7 is control-connected to the driver 9.

[0028] It should be noted that: the preset horizontal tolerance range of the control unit 7 is ±0.05mm / m (a standard for high precision in industrial equipment); the guide clamping force threshold of the first pressure sensor 12 is set to 50-80N (suitable for 1-5mm thick corrugated cardboard), and the pressing force threshold of the second pressure sensor 20 is set to 100-150N (to ensure that the glue spreads fully without damaging the cardboard); the spacing between the glue application holes of the glue application head 15 is 5-8mm, and the amount of glue applied is adjusted by the control unit 7 in conjunction with the glue supply pump of the glue storage tank 14 (e.g., the amount of glue applied to a single corrugated cardboard is 0.2-0.3g / cm), and the glue supply pump is installed on the pipe of the glue storage tank 14 connected to the glue application head 15, but the glue supply pump is not shown in the figure.

[0029] In this embodiment: After the equipment is started, the level sensor 6 monitors the attitude of the frame 1 in real time and transmits the data to the control unit 7. After the control unit 7 determines that the level is out of tolerance, it instructs the driver 9 at a specific position to drive the electric leveling support 8 to perform height compensation, thereby forming a real-time, closed-loop leveling system. At the same time, the automatic positioning guide mechanism 4 precisely guides the carton: the linear drive module 10 pushes the guide plate 11 to clamp the carton, and the first pressure sensor 12 on it monitors the clamping force in real time and feeds the signal back to the control system to ensure that the clamping force is stable so as not to cause the carton to deviate or crush the cardboard. Subsequently, the carton enters the glue coating and pressing mechanism 5. The glue coating head 15 evenly applies the adhesive from the glue storage tank 14. The pressing component 16, driven by the electric lifting device 17, presses down and completes the bonding through the pressing roller 19. During this process, the second pressure sensor 20 monitors in real time and ensures that the pressing force is accurate and controllable.

[0030] As a technical optimization of this utility model, the automatic positioning guide mechanism 4 includes two sets of guide components arranged symmetrically. Each set of guide components includes a linear drive module 10 fixed on the frame 1, a guide plate 11 driven to translate by the linear drive module 10, and a first pressure sensor 12 set on the guide plate 11 for detecting the pressure between the guide plate and the side of the carton.

[0031] In this embodiment, the pressure between the guide plate 11 and the side of the carton is detected in real time by the first pressure sensor 12, avoiding the problems of "deviation" or "crushing" caused by manual experience judgment, realizing precise control of the guide clamping force, and improving the stability of carton conveying and forming quality.

[0032] As a technical optimization of this utility model, the glue application and pressing mechanism 5 includes a gantry frame 13, a glue storage tank 14 installed on the gantry frame 13, a glue application head 15 connected to the glue storage tank 14 through a pipe, a pressing component 16 located downstream of the glue application head 15, and an electric lifting device 17 that drives the pressing component 16 to rise and fall vertically.

[0033] In this embodiment, the height of the pressing component 16 is adjusted by the electric lifting device 17 to adapt to the pressing requirements of corrugated cardboard of different thicknesses, avoiding "weak adhesion" or "cardboard damage" caused by fixing the pressing height. At the same time, it integrates gluing and pressing functions, simplifies the equipment structure, and improves production continuity.

[0034] As a technical optimization of this utility model, the pressing assembly 16 includes a mounting plate 18 connected to the output end of the electric lifting device 17, a pressing roller 19 rotatably connected to the mounting plate 18 via a bearing, and a second pressure sensor 20 disposed between the mounting plate 18 and the electric lifting device 17 for monitoring the pressing force.

[0035] In this embodiment: the pressure of the pressing roller 19 on the carton is monitored in real time by the second pressure sensor 20, and the pressing force is dynamically adjusted in conjunction with the electric lifting device 17 to ensure that cartons of different specifications can achieve the effect of "firm adhesion and no crushing", thereby improving the consistency of pressing quality.

[0036] As a technical optimization of this utility model, the linear drive module 10 is a servo electric slide table or a ball screw slide table.

[0037] In this embodiment, a high-precision drive component is selected to ensure the positional accuracy of the guide plate 11 during translation, avoid guide offset caused by ordinary drive components, and further ensure the accuracy of carton conveying and positioning.

[0038] As a technical optimization of this utility model, the control unit 7 is a PLC or microcontroller. The control unit 7 has a preset horizontal tolerance range. When the detection data of the horizontal sensor 6 exceeds the range, the control unit 7 can automatically adjust the height of the corresponding electric leveling support 8.

[0039] In this embodiment: by presetting a horizontal tolerance range, the control unit 7 can respond to the detection data of the horizontal sensor 6 in real time and automatically drive the electric leveling support 8 to compensate for horizontal drift, thus solving the problem that the existing patented static leveling cannot cope with operational instability and ensuring the long-term operational stability of the equipment.

[0040] As a technical optimization of this utility model, the bottom of the electric leveling support 8 is provided with a shock-absorbing pad 21, which is made of rubber or polyurethane.

[0041] In this embodiment: the vibration of the equipment during operation is absorbed by the shock-absorbing pad 21, which reduces the interference of vibration on the detection accuracy of the horizontal sensor 6, while reducing equipment noise, protecting the ground from damage caused by the heavy pressure of the equipment, and improving the adaptability of the equipment to the operating environment.

[0042] Working principle and usage process of this utility model:

[0043] When the carton gluing machine is powered on, the adaptive leveling system 3 automatically starts. The level sensor 6 detects the initial level state of the frame 1, and the control unit 7 drives the electric leveling feet 8 to complete the initial leveling, ensuring that the frame 1 is in a level state. At the same time, the electric lifting device 17 of the glue application and pressing mechanism 5 drives the pressing roller 19 to reset to the initial high position, and the glue storage tank 14 is ready to supply glue. The control unit 7 presets the level tolerance range, the guide clamping force threshold of the first pressure sensor 12, and the pressing force threshold of the second pressure sensor 20, and sets the initial spacing of the guide plates 11 of the linear drive module 10 according to the carton specifications. The corrugated cardboard is placed on the conveying mechanism 2, and the conveying mechanism 2 drives the carton to move into the equipment. When the carton enters the area of ​​the automatic positioning guide mechanism 4, the linear drive module 10 drives the guide plates 11 on both sides to move closer to the carton. The first pressure sensor 12 provides real-time feedback of pressure data. After reaching the preset threshold, the guide plates 11 maintain the clamping state, realizing the centering and positioning of the carton. The positioned carton continues to be conveyed to Below the glue applicator head 15 of the glue applicator pressing mechanism 5, the glue storage tank 14 applies glue to the overlapping edge of the carton through the glue applicator head 15. After the glue application is completed, the carton enters the pressing assembly 16 area. The electric lifting device 17 drives the pressing roller 19 to descend. After the second pressure sensor 20 detects that the pressing force has reached the preset value, the pressing roller 19 rotates synchronously with the carton conveyor to continuously press the overlapping edge after glue application. Throughout the production process, the level sensor 6 continuously monitors the level status of the frame 1. If horizontal drift is caused by vibration or ground subsidence, the control unit 7 immediately drives the electric leveling support 8 for dynamic compensation. The first pressure sensor 12 and the second pressure sensor 20 continuously provide force data to ensure that the guide clamping force and pressing force are always within the preset range. The pressed and formed carton is output from the end of the conveying mechanism 2. After production is completed, the equipment power is turned off, the residual glue on the glue applicator head 15 is cleaned, and the operating status of components such as the electric leveling support 8 and the linear drive module 10 is checked regularly to ensure that the equipment is in normal working order for the next use.
