Description

Technical Field

[0001] This utility model relates to the field of CNC strip cutting machine technology, and in particular to a guide structure for CNC strip cutting machine. Background Technology

[0002] A CNC strip cutting machine is a mechanical device that uses CNC technology to achieve automated and high-precision cutting of strip materials. Its main function is to cut raw materials into uniform strip products according to preset dimensions.

[0003] Chinese Patent Publication No. CN217072483U discloses a CNC rubber strip cutting machine, including a base, symmetrically fixed vertical plates on the top of the base, support rollers uniformly rotating between the vertical plates, and a motor-driven conveying roller rotatably connected to one side. A pressure roller is provided on the top of the conveying roller. Through the arrangement of counter-rotating screws, stepper motors, and centering rods, after the rubber sheet is placed on the support rollers, the stepper motor is started. The counter-rotating screws drive two sets of sliding plates and the centering rods on both sides to move relative to each other, centering the rubber sheet and reducing cutting deviations caused by manual tilting, thus improving cutting accuracy.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When CNC strip cutting machines transport materials, the materials may tilt or slide under their own weight or slight external interference. If there is a lack of timely guidance, the materials will deviate, resulting in uneven strip cutting. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing CNC strip cutting machine lacks guidance when transporting materials, resulting in uneven strip cutting. To address this, we propose a guiding structure for CNC strip cutting machines.

[0006] To achieve the above objectives, this application adopts the following technical solution: a guide structure for a CNC strip cutting machine, comprising: a worktable, and a control box disposed on the upper surface of the worktable, a housing disposed on the upper surface of the worktable, a cutting component for strip cutting disposed inside the housing, and a guide component for transporting materials disposed on the upper surface of the worktable.

[0007] The guiding assembly includes a cutting table fixedly mounted on the upper surface of the workbench, and a roller conveyor set on one side of the cutting table. An electric push rod A is fixedly mounted on the inner wall of the housing via a mounting block. The telescopic end of the electric push rod A is fixedly mounted with a mounting bracket via bolts. A rotating drum is rotatably connected inside the mounting bracket. One end of the rotating drum is connected to the output end of the motor via a synchronous belt and a synchronous pulley. An anti-slip guide plate is hinged to the inner wall of the housing. An electric push rod B is hinged to the movable end of the anti-slip guide plate. The fixed end of the electric push rod B is hinged to the inner wall of the housing. An infrared sensor and a laser rangefinder are installed inside the housing. Both the infrared sensor and the laser rangefinder are connected to the control box for signal transmission.

[0008] Preferably, the cutting assembly includes a hydraulic cylinder fixedly mounted on the upper surface of the housing, and a hydraulic rod disposed at the bottom of the hydraulic cylinder. The hydraulic rod extends through the lower part of the housing, and a connecting frame is fixedly mounted at the bottom end of the hydraulic rod by bolts. A drive motor is disposed inside the connecting frame, and a cutting blade assembly is disposed at the output end of the drive motor.

[0009] Preferably, the cutting blade assembly includes a rotating rod rotatably connected inside the connecting frame, and a circular blade movably sleeved on the outer surface of the rotating rod. Multiple sets of circular blades are provided, and each set of circular blades is fixed to the outer surface of the rotating rod by an adjusting screw. The output end of the drive motor is connected to one end of the rotating rod.

[0010] Preferably, the outer surface of the connecting frame is provided with a scale strip.

[0011] Preferably, an inclined guide plate is fixedly installed on one side of the cutting table.

[0012] Preferably, a receiving tray is provided at the bottom of the inclined guide plate, and one side of the receiving tray is fixed to one side of the worktable by bolts.

[0013] Preferably, a maintenance cover is hinged to one side of the housing, the inside of the maintenance cover is provided with an observation glass, and the outer surface of the maintenance cover is provided with a handle.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] In this invention, the device places the material to be cut on a roller conveyor and starts it with power, allowing the material to be transported close to the cutting table. The infrared sensor and laser rangefinder at this location can transmit the detected material position and size information to the control box. The control box then controls the extension and retraction of the electric push rod A, thereby driving the drum to fit tightly against the upper surface of the material. The motor drives the drum to rotate, thus restricting the upper part of the material. At the same time, combined with the anti-slip guide plate of the electric push rod B rotating at the hinge point, the material is laterally restricted. Therefore, materials of different sizes can be accurately guided into the cutting area. Attached Figure Description

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Reference Figure 1 As shown, this utility model provides a technical solution: a guide structure for a CNC strip cutting machine, including: a worktable 1, and a control box 2 disposed on the upper surface of the worktable 1. A housing 3 is disposed on the upper surface of the worktable 1, and a cutting component 4 for strip cutting is disposed inside the housing 3. A guide component 6 for transporting materials is disposed on the upper surface of the worktable 1.

[0025] Reference Figures 1-5As shown in this embodiment: the guide assembly 6 includes a cutting table 61 fixedly installed on the upper surface of the workbench 1, and a roller conveyor 62 disposed on one side of the cutting table 61. An electric push rod A63 is fixedly installed on the inner wall of the housing 3 via a mounting block 31. A mounting bracket 64 is fixedly installed on the telescopic end of the electric push rod A63 via bolts. A rotating drum 65 is rotatably connected inside the mounting bracket 64. One end of the rotating drum 65 is connected to the output end of the motor 67 via a synchronous belt 66 and a synchronous pulley 661. An anti-slip guide plate 68 is hinged to the inner wall of the housing 3. An electric push rod B681 is hinged to the movable end of the anti-slip guide plate 68. The fixed end of the electric push rod B681 is hinged to the inner wall of the housing 3. An infrared sensor is installed inside the housing 3. Sensors 69 and the laser rangefinder, as well as infrared sensors 69 and the laser rangefinder, are all connected to the control box 2. The material to be cut is placed on the roller conveyor 62 and powered on, allowing the material to be transported close to the cutting table 61. Here, the infrared sensor 69 and the laser rangefinder detect the material's position and size, transmitting the data to the control box 2. The control box 2 then controls the extension and retraction of the electric push rod A63, causing the rotating drum 65 to press against the upper surface of the material. The motor 67 drives the drum to rotate, thus restricting the upper part of the material. A pressure sensor can also be added for further control. Simultaneously, the anti-slip guide plate 68 of the electric push rod B681 rotates at a hinge point. Figure 2 It can be seen that there are two sets of electric push rods B681 and anti-slip guide plates 68. The two sets of electric push rods B681 can be synchronized to extend and retract synchronously through a synchronizer, thereby limiting and guiding the material on both sides. In addition, the surface of the anti-slip guide plate 68 is made of a material with a low coefficient of friction, so it can prevent material deformation or jamming while ensuring the lateral limiting effect. In summary, the guide assembly 6 accurately guides materials of different sizes into the cutting area.

[0026] The cutting assembly 4 includes a hydraulic cylinder 41 fixedly mounted on the upper surface of the housing 3, and a hydraulic rod located at the bottom of the hydraulic cylinder 41. The hydraulic rod extends through the lower part of the housing 3, and a connecting frame 42 is fixedly mounted at the bottom end of the hydraulic rod by bolts. A drive motor 43 is installed inside the connecting frame 42, and a cutting blade assembly 44 is installed at the output end of the drive motor 43. According to the actual thickness of the material, the hydraulic cylinder 41 drives the hydraulic rod to extend and retract, thereby moving the connecting frame 42 up and down to a suitable position. Then, the drive motor 43 drives the cutting blade assembly 44 to rotate, thereby contacting the material and cutting it.

[0027] The cutting blade assembly 44 includes a rotating rod 441 rotatably connected inside the connecting frame 42, and circular blades 442 movably sleeved on the outer surface of the rotating rod 441. Multiple sets of circular blades 442 are provided, and each set of circular blades 442 is fixed to the outer surface of the rotating rod 441 by an adjusting screw. The output end of the drive motor 43 is connected to one end of the rotating rod 441. Since multiple sets of circular blades 442 are provided, and in actual operation, they are often divided into modules to facilitate quick adjustment of the cutting spacing, and then installed and disassembled by adjusting screws.

[0028] The outer surface of the connecting bracket 42 is provided with a scale strip to facilitate better confirmation of the spacing of the circular blades 442.

[0029] An inclined guide plate 5 is fixedly installed on one side of the cutting table 61 to facilitate the downward movement of the cut material and prevent blockage of the cutting area.

[0030] The bottom of the inclined guide plate 5 is provided with a receiving tray 7. One side of the receiving tray 7 is fixed to one side of the workbench 1 by bolts. The material conveyed by the inclined guide plate 5 eventually falls into the receiving tray 7 at the bottom. Then the receiving tray 7 can be disassembled for convenient centralized transfer of the cut strips.

[0031] A maintenance cover plate 8 is hinged to one side of the housing 3. An observation glass 81 is provided inside the maintenance cover plate 8. A handle 82 is provided on the outer surface of the maintenance cover plate 8. The maintenance cover plate 8 on one side of the housing 3 can be opened by using the handle 82, so as to facilitate the maintenance of its internal components. The observation glass 81 facilitates real-time observation of the inside of the housing 3 in the working state.

[0032] Working principle: The material to be cut is placed on the roller conveyor 62 and powered on, transporting the material to a position close to the cutting table 61. Infrared sensors 69 and laser rangefinders at this location detect the material's position and size. Multiple laser rangefinders are installed. The data is then transmitted to the control box 2, which controls the extension and retraction of the electric push rod A63. This causes the rotating drum 65 to come into contact with the upper surface of the material, and the motor 67 drives its rotation, thus restricting the upper part of the material. A pressure sensor can be added for further control. Simultaneously, the anti-slip guide plate 68 of the electric push rod B681 rotates at a hinge point. Figure 2It can be seen that both the electric push rod B681 and the anti-slip guide plate 68 are provided in two sets. The two sets of electric push rods B681 can be synchronized to extend and retract synchronously through a synchronizer, thereby limiting and guiding the material on both sides. In addition, the surface of the anti-slip guide plate 68 is made of a low-friction coefficient material, so it can ensure the lateral limiting effect while avoiding material deformation or jamming. In summary, the guide assembly 6 accurately guides materials of different sizes into the cutting area. Next, based on the actual material thickness data measured by the laser rangefinder, the hydraulic cylinder 41 is controlled to drive the hydraulic rod to extend and retract, thereby moving the connecting frame 42 up and down to the appropriate position. Then, the drive motor 43 drives the cutting blade assembly 44 to rotate, thereby contacting the material and cutting it. Since there are multiple sets of circular blades 442, and in actual operation, they are often divided into modules to facilitate quick adjustment of the cutting spacing, and then installed and disassembled by adjusting the screw. After cutting, the material is guided downward by the inclined guide plate 5 to prevent blockage of the cutting area, and finally falls into the receiving tray 7 at the bottom. Then, the receiving tray 7 can be disassembled for convenient centralized transfer of the cut strips. In addition, the inspection cover 8 on one side of the housing 3 can be opened by the handle 82, which facilitates the inspection of its internal components, and the observation glass 81 allows for real-time observation of the inside of the housing 3 in the working state.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
