Technical Field

[0001] This utility model belongs to the technical field of packaging material performance testing equipment, specifically relating to a tool-simulated bag-cutting experimental platform. Background Technology

[0002] In port logistics and material handling, cutting ton bags (FIBCs) is a common operation. Current research on ton bag cutting lacks a professional experimental platform, relying mostly on on-site observation or simple mechanical simulation, which has the following drawbacks: 1) Inability to precisely control cutting speed, stroke, and other parameters; 2) Difficulty in real-time acquisition of stress data during the cutting process; 3) Insufficient structural stability, leading to poor repeatability of experimental results; 4) Limited functionality, unable to simulate cutting conditions under different material filling states.

[0003] Existing technologies with similar equipment suffer from complex structures and insufficient data acquisition accuracy, failing to meet the professional requirements of ton bag cutting experiments. Therefore, there is an urgent need to design a tool simulation ton bag cutting experimental platform that is structurally stable, precisely controlled, and reliably acquires data. Summary of the Invention

[0004] To address the problems of inaccurate parameter control, incomplete data acquisition, and poor structural stability in the existing equipment, this invention provides a tool-simulated bag-cutting experimental platform.

[0005] The tool simulation bag-cutting experimental platform of this utility model includes a load-bearing frame, a power roller and a transmission motor installed on one side of the load-bearing frame, a driven roller installed on the opposite side of the load-bearing frame, a long strip-shaped material frame installed on the top of the load-bearing frame, an electric push rod installed inside the load-bearing frame and capable of vertical extension and retraction, a mounting plate installed on the electric push rod, a horizontal linear module installed on the mounting plate, a blade and sensor unit installed on the linear module, and a controller installed on the load-bearing frame. The tops of both the driven roller and the driven roller are lower than the top of the support frame, and the drive motor is connected to the driven roller via a chain; the driven roller, the driven roller, and the material frame are all horizontal and parallel to each other; Vertical slide rails are installed on opposite sides inside the load-bearing frame, and the two ends of the mounting plate are slidably connected to the slide rails on both sides.

The sensor unit includes a tension / compression sensor and a sensor base. One side of the tension / compression sensor is connected to the blade holder, and the other side is connected to the sensor base. It is used to collect the pressure when the cutter is cutting. The sensor base is mounted on the linear module. A strip-shaped through hole is opened at the bottom of the material frame along the length of the material frame; the strip-shaped through hole is located directly above the cutter so that the cutter can pass through after it is raised and so that the cutter can move along the strip-shaped through hole; The controller is connected to the drive motor, electric actuator, and linear module and controls the start and stop of the drive motor, electric actuator, and linear module.

[0006] Furthermore, the load-bearing frame includes a top rectangular frame, a bottom rectangular frame, and four support rods. The four support rods are connected between the top and bottom rectangular frames. A support plate is installed on the bottom rectangular frame, and an electric push rod is mounted on the support plate. A vertical slide rail is installed between the top and bottom rectangular frames, and sliders are provided at both ends of the mounting plate. The sliders and slide rails work together. This design ensures structural stability and high reliability.

[0007] Furthermore, the linear module includes a stepper motor, a lead screw connected to the stepper motor, and a mounting block threaded onto the lead screw.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0014] This utility model is a tool simulation bag-cutting experimental platform, including a load-bearing frame 1, a power roller 2 and a transmission motor 3 installed on one side of the load-bearing frame 1, a driven roller 4 installed on the opposite side of the load-bearing frame 1, a long strip-shaped material frame 5 installed on the top of the load-bearing frame 1, an electric push rod 6 installed inside the load-bearing frame 1 and capable of vertical extension and retraction, a mounting plate 7 installed on the electric push rod 6, a horizontal linear module 8 installed on the mounting plate 7, a blade part 9 and a sensor part installed on the linear module 8, and a controller 10 installed on the load-bearing frame 1.

[0015] Specifically, the load-bearing frame 1 includes a top rectangular frame, a bottom rectangular frame, and four support rods. The four support rods are connected between the top and bottom rectangular frames. The entire load-bearing frame 1 is welded from stainless steel square tubing, with dimensions such as 840×690×450mm, a yield strength of such as 215MPa, and a safety factor of such as 16.487 to ensure structural stability. A stainless steel support plate 13 is welded to the bottom rectangular frame, and an electric push rod 6 is mounted on the support plate 13. The top of the electric push rod 6 is fixed to the mounting plate 7 by angle iron. The electric push rod 6 has a thrust of such as 250N and a stroke of such as 200mm, meeting the 150mm cutting stroke requirement. Side plates 11 are provided on the four sides of the load-bearing frame 1 to protect the internal components. The drive motor 3 is mounted on the side plate 11 on the side of the power roller 2. Both ends of the driving roller 2 and the driven roller 4 are fixed to the side plate via connecting rods 12. The tops of the driving roller 2 and the driven roller 4 are lower than the top of the load-bearing frame 1. The driving roller 2, the driven roller 4, and the material frame 5 are all horizontal and parallel. The motor shaft of the drive motor 3 has a small sprocket 31, and the shaft of the driving roller 2 has a large sprocket 21. The drive motor 3 and the driving roller 2 are connected and driven by a chain 32, that is, the chain 32 is connected to the small sprocket 31 and the large sprocket 21 for transmission.

[0016] Vertical plates are installed on opposite sides inside the load-bearing frame 1. The vertical plates are welded between the top rectangular frame and the bottom rectangular frame. Vertical slide rails 72 are installed on the vertical plates. Slider blocks 71 are installed at both ends of the mounting plate 7 by angle iron. The sliders 71 and slide rails 72 are used together. The slide rails and sliders use standard parts (model EGH30CA). The length of the slide rail is 360mm.

[0017] The cutting unit 9 includes a cutter holder 91, a cutting blade 92, and a blade cover 93. The cutter holder 91 is mounted on the linear module 8 and can move horizontally. The cutting blade 92 is mounted on the cutter holder 91 and pressed down by the blade cover 93. The cutting blade 92 is small and sharp at the top and large at the bottom, with the upper end of the cutting blade 92 extending out of the cutter holder 91. The cutter holder 91 has a mounting groove, and the bottom of the cutting blade 92 has a handle. The handle is placed in the mounting groove, and the blade cover 93 is pressed down on the handle and bolted to the cutter holder 91, thereby pressing and fixing the handle.

[0018] The linear module 8 is bolted onto the mounting plate 7. The linear module 8 includes a stepper motor, a lead screw connected to the stepper motor, and a mounting block threaded onto the lead screw. The tool holder 91 is mounted on the mounting block. The linear module 8 is model ZTH5-L5-450-BL-M10-C4, and the matching stepper motor is model YK257EC56E1, achieving a cutting speed of 80mm / s.

[0019] The sensor unit includes a tension / compression sensor 95 and a sensor base 94. One side of the tension / compression sensor 95 is connected to the blade holder 91, and the other side is connected to the sensor base 94. It is used to collect the pressure when the cutter 92 is cutting. The sensor base 94 is mounted on the mounting block of the linear module 8 by bolts.

[0020] A strip-shaped through hole 51 is made on the bottom plate of the material frame 5 along the length of the material frame 5. The strip-shaped through hole 51 is located directly above the cutter 92, allowing the cutter 92 to pass through after it is raised and to move along the strip-shaped through hole 51. That is, the horizontal movement direction of the cutter 92 is consistent with the strip-shaped through hole 51, and the length of the strip-shaped through hole 51 is greater than the stroke of the cutter 92. Specifically, bosses 52 are welded to both ends of the outer bottom surface of the material frame 5, protruding downwards. The bosses 52 extend outwards towards both ends of the material frame 5 as protrusions. Through holes are opened in the protrusions of the bosses 52, and bolts are used to install them on the load-bearing frame 1, thereby fixing the material frame 5 on the load-bearing frame 1. The height of the bosses 52 is 3mm. The material frame 5 is, for example, 840mm long, 80mm wide, and 195mm deep, used to hold stone particles with a particle size of 6-8mm. The width of the strip-shaped through hole 51 is 3mm.

[0021] The controller 10 is mounted on the side plate 11 and is connected to the drive motor 3, the electric push rod 6 and the stepper motor of the linear module 8. It controls the start and stop of the drive motor 3, the electric push rod 6 and the stepper motor. The rotation and stop of the stepper motor are driven by the controller 10 through the stepper motor driver. The controller 10 is a programmable logic controller, model Siemens PLC S7-1200 1214C DC / DC / DC.

[0022] In practical use, first, a roll of cloth is mounted on the driven roller 4. The end of the cloth roll passes through the space between the two protrusions 52 at the bottom of the material frame 5 and is wound around the drive roller 2. Then, the drive motor 3 is turned on to drive the drive roller 2 to rotate. The rotation of the drive roller 2 drives the cloth to move, and the movement of the cloth drives the driven roller 4 to rotate, thus updating the cloth. Then, the drive motor 3 is stopped, and the electric push rod 6 is turned on to push the mounting plate 7 to rise. The rise of the mounting plate 7 drives the cutter 92 to rise. The cutter 92 passes through the cloth and the strip-shaped through hole 51 at the bottom of the material frame 5 in sequence, and enters the material frame 5 for pre-cutting. When loading materials, the length of the cutter 92 inserted does not exceed the height of the material in the material frame 5, and the electric push rod 6 stops; the stepper motor of the linear module 8 is started to drive the cutter 92 to move horizontally. The cutter 92 cuts the ton of cloth, and the tension and pressure sensor 95 detects the horizontal component of the cutting resistance in real time and collects the data, which is transmitted to the external host computer through the acquisition card. After the cutter 92 moves horizontally by 500mm, the stepper motor stops; then the electric push rod 6 is started to drive the mounting plate 7 to descend, and the electric push rod 6 stops after the cutter 92 is pulled out of the ton of cloth; the linear module 8 is started to drive the cutter 92 to reset, and the above process is repeated.

[0023] Unless otherwise specified, all technologies mentioned above refer to existing technologies.

[0024] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification.
