Description

Technical Field

[0001] This utility model relates to the technical field of packaging box processing, and specifically to a packaging box processing indentation device. Background Technology

[0002] In the field of packaging box processing, creasing devices are equipment used to form packaging boxes. They are widely used in packaging production lines in industries such as food, pharmaceuticals, and electronics. Existing packaging box creasing devices typically include a basic conveying mechanism and a creasing mechanism. The packaging box is conveyed to the creasing area by a conveyor belt or rollers, and a pre-set crease is formed on the surface of the box using a creasing knife. This can meet the basic creasing requirements in mass production. Some devices also allow for rough adjustment of the creasing wheel position through manual or semi-automatic adjustment mechanisms. They play an important role in the large-scale production of the packaging industry and have become an indispensable standardized piece of equipment in the packaging box processing flow.

[0003] Existing technologies suffer from insufficient control over indentation precision and weak automatic adjustment capabilities. This technical solution addresses these issues through innovative design and several structural improvements. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a packaging box creasing device. This device utilizes a positioning mechanism where guide wheels roll on the box surface, a compression spring provides elasticity to slide the guide rod, and a static magnetic grating displacement sensor transmits thickness signals to a PLC controller. Combined with vertical and horizontal adjustment components of the creasing mechanism, it achieves precise adjustment of the vertical height and horizontal position of the creasing wheels. Furthermore, a pressure sensor in the force monitoring module collects creasing force data in real time, which is then fed back to the PLC controller via a data transmission module. This solves the problem of insufficient creasing precision control, achieving accurate creasing position, uniform depth, and force that meets process requirements. The control module (PLC controller) is electrically connected to the conveyor motor, static magnetic grating displacement sensor, vertical adjustment motor, drive motor, horizontal adjustment cylinder, data transmission module, and control panel to achieve real-time control and manual intervention of parameters such as conveying speed, creasing height, and creasing force. This improves molding quality, and the anti-slip texture on the conveyor belt surface prevents box slippage and offset, solving the problem of weak automatic adjustment capabilities. Ultimately, this achieves efficient, stable, and automated production of packaging box creasing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A packaging box processing creasing device includes a frame, a conveying mechanism, a creasing mechanism, a positioning mechanism, a force monitoring module, a data transmission module, and a control module. The frame has supporting feet at its bottom. The conveying mechanism is horizontally mounted on the frame and includes two sets of parallel conveying rollers, a conveyor belt fitted onto the two rollers, and a conveyor motor driving the rollers. The conveyor motor is fixed to one side of the frame via a motor mounting plate, and its output shaft is connected to the end of one set of conveying rollers via a coupling. The creasing mechanism is located at the feed end of the conveying mechanism and includes a vertical adjustment component, a horizontal adjustment component, a creasing wheel, and a drive motor that is connected to one end of the creasing wheel via a mounting plate. The vertical adjustment component is fixed to the upper part of the frame via an adjustment bracket. The positioning mechanism is symmetrically arranged on both sides of the conveying mechanism and includes a positioning plate, a static magnetic grating displacement sensor, a guide wheel, a compression spring, and a guide rod. The positioning plate is vertically positioned on one side of the conveyor belt, the static magnetic grating displacement sensor is positioned on one side of the positioning plate, the compression spring is fitted onto the guide rod, the guide rod passes through the positioning plate, and the guide wheel is positioned below the guide rod.

[0007] The vertical adjustment assembly consists of a vertical sliding optical shaft slidably mounted on an adjustment bracket, a vertical adjustment frame with a vertical slider at each end, a vertical adjustment plate located on one side of the vertical adjustment frame, and a vertical adjustment motor with an output gear at its output end mounted on the adjustment bracket. One end of the vertical adjustment plate is connected to the vertical adjustment frame by bolts, and a rack is provided in the middle adjustment groove of the vertical adjustment plate, which meshes with the output gear.

[0008] The lateral adjustment assembly includes two parallel lateral slide rods, a lateral slide plate frame slidably sleeved on the lateral slide rods, and a lateral adjustment cylinder located at one end of the vertical adjustment frame. The two ends of the lateral slide rods are fixedly connected to the lower end of the vertical adjustment frame, and one side of the lateral slide plate frame is fixedly connected to the output end of the lateral adjustment cylinder by a locking bolt.

[0009] The surface of the conveyor belt is provided with anti-slip texture.

[0010] The vertical plate of the adjustment bracket has scale lines on its inner side, and the vertical adjustment frame of the vertical adjustment assembly has indicator lines corresponding to the scale lines.

[0011] The outer surface of the lateral slide bar of the lateral adjustment component is provided with scale lines, and the lateral slide frame is provided with indicator lines corresponding to the scale lines.

[0012] The indentation wheel is rotatably mounted on the lower end of the transverse slide frame via an axle and bearing.

[0013] The force monitoring module is a pressure sensor embedded between the indentation wheel and the wheel axle, and the pressure sensor is electrically connected to the data transmission module.

[0014] The control module includes a PLC controller fixed to one side of the frame via a control box and a control panel embedded in the side of the control box. The PLC controller is electrically connected to the conveyor motor, the static magnetic grating displacement sensor, the vertical adjustment motor, the drive motor, the horizontal adjustment cylinder, the data transmission module, and the control panel.

[0015] The control module also includes an alarm that is electrically connected to the PLC controller. The alarm is an audible and visual alarm and is fixed on the top of the control box.

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

[0017] 1. The positioning mechanism uses a guide wheel that rolls on the surface of the box, a compression spring that provides elastic force to make the guide rod slide, and a static magnetic grating displacement sensor that transmits thickness signals to the PLC controller. Combined with the vertical and horizontal adjustment components of the indentation mechanism, the vertical height and horizontal position of the indentation wheel are precisely adjusted. The pressure sensor of the force monitoring module collects indentation force data in real time and feeds it back to the PLC controller through the data transmission module. This achieves a precise control effect with accurate indentation position, uniform depth, and force that meets process requirements.

[0018] 2. By electrically connecting the control module PLC controller with the conveyor motor, static magnetic grating displacement sensor, vertical adjustment motor, drive motor, horizontal adjustment cylinder, data transmission module and control panel, the system achieves real-time control and manual intervention of parameters such as conveying speed, indentation height and indentation force, thereby improving the forming quality. The anti-slip texture on the conveyor belt surface prevents the box board from sliding and deviating, achieving efficient, stable and automated production of packaging box indentation processing.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figure 1-5As shown, this utility model relates to a creasing device for packaging box processing, including a frame 1, a conveying mechanism 2, a creasing mechanism 3, a positioning mechanism 6, a force monitoring module 7, a data transmission module located in a control box 8, and a control module located in the control box 8; the frame 1 is provided with support feet 10 at the bottom; the conveying mechanism 2 is horizontally mounted on the frame 1, and the conveying mechanism 2 includes two sets of parallel conveying rollers 20, a conveyor belt 21 sleeved on the two conveying rollers 20, and a conveying motor 22 that drives the conveying rollers 20 to rotate. The conveying motor 22 is fixed to one side of the frame 1 by a motor code plate 23, and its output shaft 24 is connected to the end of a set of conveying rollers 20 through a coupling 25. The surface of the conveyor belt 21 is provided with anti-slip texture; the indentation mechanism 3 is located at the feed end of the conveyor mechanism 2. The indentation mechanism 3 includes a vertical adjustment component 30, a horizontal adjustment component 31, an indentation wheel 32, and a drive motor 34 that is connected to one end of the indentation wheel 32 via a mounting plate 33. The vertical adjustment component 30 is fixed to the upper part of the frame 1 by an adjustment bracket 4. The indentation wheel 32 is rotatably mounted on the lower end of the horizontal slide frame 311 via a wheel axle and bearings; the positioning mechanism 6 is symmetrically arranged on both sides of the conveyor mechanism 2. The positioning mechanism 6 includes a positioning plate 60, a static magnetic grating displacement sensor 61, a guide wheel 62, a compression spring 63, and a guide rod 64. The positioning plate 60 is vertically arranged. On one side of the conveyor belt 21, a static magnetic grating displacement sensor 61 is located on one side of the positioning plate 60. A compression spring 63 is sleeved on the guide rod 64, which passes through the positioning plate 60. A guide wheel 62 is located below the guide rod 64. Below the indentation wheel 32, there is an auxiliary roller 5 that cooperates with it to press the box plate. The auxiliary roller 5 is rotatably connected to the adjusting bracket 4 through a bearing. When the box plate is fed onto the conveyor belt 21 on the conveyor mechanism 2, the conveyor motor 22 drives the conveyor roller 20 to rotate. The conveyor roller 20 drives the conveyor belt 21 to move forward. When the box plate passes under the positioning mechanism 6, the guide wheel 62 rolls on the box plate. The compression spring sleeved on the guide rod 64... One end of spring 63 abuts against the top plate, and the other end is fixed to the guide rod 64. The compression spring 63 provides a downward elastic force to the guide rod 64, so that it always keeps the guide wheel 62 in contact with the box plate. At the same time, according to the thickness of the box plate, the guide rod 64 slides on the positioning plate 60, thereby causing the movable end of the static magnetic grating displacement sensor 61 fixed on the guide rod 64 to be relatively displaced from the sensing end fixed on the positioning plate 60. The static magnetic grating displacement sensor 61 transmits this displacement signal to the data transmission module, and the data transmission module uploads it to the control module. When the box plate is conveyed to the auxiliary roller 5, the control module sends a start signal to the indentation mechanism 3, and the indentation mechanism 3 starts working.

[0028] like Figure 3-4As shown, the vertical adjustment assembly 30 consists of a vertical sliding optical shaft 300 slidably mounted on the adjustment bracket 4, a vertical adjustment frame 301 with a vertical slider 3010 at each end, a vertical adjustment plate 302 located on one side of the vertical adjustment frame 301, and a vertical adjustment motor 304 mounted on the adjustment bracket 4 with an output gear 303 at its output end. One end of the vertical adjustment plate 302 is connected to the vertical adjustment frame 301 by bolts. A rack 3021 is provided in the middle adjustment groove 3020 of the vertical adjustment plate 302. 1. The vertical slider 3010 is engaged with the output gear 303 and is slidably connected to the slide groove 400 on the inner side of the adjustment bracket 4. When the vertical adjustment motor 304 receives the start signal from the control module, it drives the output gear 303 to move the vertical adjustment plate 302 downward, thereby moving the vertical adjustment frame 301 downward. The vertical sliding optical shaft 300 is used to keep the vertical adjustment frame 301 vertically stable, and the vertical slider 3010 is slidably engaged with the slide groove 400 of the adjustment bracket 4 to keep the vertical adjustment frame 301 laterally stable when it moves.

[0029] like Figure 3-4 As shown, the lateral adjustment assembly 31 includes two parallel lateral slide rods 310, a lateral slide plate frame 311 slidably sleeved on the two lateral slide rods 310, and a lateral adjustment cylinder 312 located at one end of the vertical adjustment frame 301. The two ends of the lateral slide rods 310 are fixedly connected to the lower end of the vertical adjustment frame 301, and one side of the lateral slide plate frame 311 is fixedly connected to the output end of the lateral adjustment cylinder 312 by a locking bolt. When the height adjustment of the vertical adjustment assembly 30 is completed, the control module sends a signal to the lateral adjustment cylinder 312, and the lateral adjustment cylinder 312 drives the lateral slide plate frame 311 to slide on the lateral slide rods 310, thereby changing the pressing pattern of the indentation wheel 32 on the box plate laterally.

[0030] The vertical plate 40 of the adjustment bracket 4 is provided with scale lines on its inner side, and the vertical adjustment frame 301 of the vertical adjustment component 30 is provided with indicator lines corresponding to the scale lines, so that the control module can adjust the vertical adjustment motor 304, change the vertical height of the indentation wheel 32, and adjust the indentation depth of the box plate.

[0031] The outer surface of the lateral slide bar 310 of the lateral adjustment component 31 is provided with scale lines, and the lateral slide frame 311 is provided with indicator lines corresponding to the scale lines, so that the control module can adjust the lateral adjustment cylinder 312 and change the lateral horizontal position of the indentation wheel 32.

[0032] like Figure 5 As shown, the force monitoring module 7 is a pressure sensor embedded between the indentation wheel 32 and the wheel axle, and the pressure sensor is electrically connected to the data transmission module.

[0033] The control module includes a PLC controller fixed to one side of the frame 1 via a control box 8 and a control panel embedded in the side of the control box 8. The PLC controller is electrically connected to the conveyor motor 22, the static magnetic grating displacement sensor 61, the vertical adjustment motor 304, the drive motor 34, the horizontal adjustment cylinder 312, the data transmission module, and the control panel.

[0034] The control module also includes an alarm 9 that is electrically connected to the PLC controller. The alarm 9 is an audible and visual alarm and is fixed on the top of the control box 8.

[0035] like Figure 1-5 As shown, the frame 1 supports the creasing device, and its bottom support feet 10 ensure stable operation. The conveying mechanism 2, driven by the conveying motor 22, smoothly conveys the packaging box board to the creasing area. The creasing mechanism 3 achieves precise positioning of the creasing wheel 32 through the vertical adjustment component 30 and the horizontal adjustment component 31, and fine-tunes the vertical height through the adjustment motor. The horizontal adjustment component 31, through the horizontal adjustment cylinder 312, pushes the horizontal slide frame 311 along the horizontal slide bar 310 to complete horizontal positioning. The creasing wheel 32 directly contacts the packaging box board to complete the creasing. The positioning mechanism 6 monitors the thickness (height) of the packaging box board and transmits the thickness signal to the PLC controller through the data transmission module. The PLC controller drives the vertical adjustment mechanism 3 according to preset parameters. The adjusting motor 304 adjusts the pressing height of the indentation roller 32 to ensure that the indentation depth matches the thickness of the packaging box. The force monitoring module 7 is used to collect indentation force data in real time through the pressure sensor, and feeds it back to the PLC controller through the data transmission module. When abnormal pressure is detected, the audible and visual alarm 9 is triggered for early warning, and the system automatically corrects itself by adjusting the parameters by a fluctuation of 10%-30%. The control module is used to control parameters such as conveying speed, indentation height, and indentation force through electrical connection. The control panel displays the operating status in real time and supports manual intervention, completing the automated and precise control of the indentation process of the packaging box, ensuring that the indentation position is accurate, the depth is uniform, and the force meets the process requirements. Furthermore, the indentation roller 32 can be replaced with a scoring knife set for crease cutting of the packaging box.

[0036] Working principle: First, the frame 1 serves as the basic support structure, with bottom support feet 10 ensuring stable operation. The conveying mechanism 2 drives one set of conveyor rollers 20 to rotate via the conveyor motor 22, causing the conveyor belt 21 with anti-slip texture to horizontally feed the packaging box panels. When the box panel enters the positioning mechanism 6 area, the guide wheel 62 rolls on the box panel surface, and the compression spring 63 sleeved on the guide rod 64 provides downward elastic force, causing the guide rod 64 to slide up and down on the positioning plate 60. The movable end and fixed end of the static magnetic grating displacement sensor 61 undergo relative displacement, transmitting the box panel thickness signal to the data transmission module. The control module uses a PLC controller. The PLC controller generates a working signal to drive the vertical adjustment motor 304. The output gear 303 meshes with the rack 3021 in the middle adjustment groove 3020 of the vertical adjustment plate 302, causing the slider 3000 of the vertical adjustment frame 301 to slide along the inner sliding groove 400 of the adjustment bracket 4. The vertical sliding optical axis 300 slides vertically on the adjustment bracket 4. The indicator line on the vertical adjustment frame 301 aligns with the scale line on the inner side of the vertical straight plate 40 of the adjustment bracket 4, accurately fine-tuning the vertical height of the indentation wheel 32. Next, the horizontal adjustment cylinder 312 pushes the horizontal sliding plate frame. 311 slides along the transverse slide bar 310, and the scale lines on the outer surface of the transverse slide bar 310 align with the indicator lines on the slide frame 311 to precisely adjust the transverse horizontal position of the indentation wheel 32. When the box board is conveyed onto the auxiliary roller 5, the control module sends a start signal to the indentation mechanism 3, driving the motor 34 to rotate the indentation wheel 32 through its output end, cooperating with the auxiliary roller 5 to indent the box board. The pressure sensor of the force monitoring module 7 is embedded between the indentation wheel 32 and the wheel axle, collecting indentation force data in real time, and feeding it back to the PLC controller via the data transmission module. When an abnormal pressure is detected, an audible and visual alarm is triggered. The system provides 9 early warnings and automatically corrects the indentation force by adjusting parameters with a fluctuation range of 10%-30%. The PLC controller of the control module is also electrically connected to the conveyor motor 22, the static magnetic grating displacement sensor 61, the vertical adjustment motor 304, the drive motor 34, the horizontal adjustment cylinder 312, the data transmission module, and the control panel to achieve real-time control of parameters such as conveying speed, indentation height, and indentation force. The control panel displays the operating status and supports manual intervention. Through collaborative work, it completes the automated and precise control of the indentation process of the packaging box, ensuring that the indentation position is accurate, the depth is uniform, and the force meets the process requirements.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, without departing from the design spirit of the present utility model, any equivalent changes or modifications made by those skilled in the art to the structure, features and principles of the present utility model should fall within the protection scope of the patent application of the present utility model.
