Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically an independent blade changing mechanism. Background Technology

[0002] In the field of noodle production and processing, the noodle cutter is one of the core components. Its function is to cut rolled-out dough sheets into noodles of different shapes and widths to meet diverse market demands. For example, common noodle varieties such as thin noodles, wide noodles, and knife-cut noodles all require cutting with noodle cutters of different specifications and shapes. In traditional noodle processing, noodle cutters are mostly fixed, and changing them requires manual disassembly and installation, which is cumbersome and inefficient. With the increasing mechanization and automation of noodle processing, noodle cutter changing mechanisms have emerged. These mechanisms can quickly and accurately change noodle cutters of different specifications, achieving continuous and efficient noodle production.

[0003] Existing tool changing mechanisms typically suffer from low efficiency, complex structure, and large space requirements. Traditional tool changing mechanisms often require multiple drive devices to complete the radial changing and axial rotation of the tool. This not only increases the complexity and cost of the equipment but also leads to a long tool changing time. In addition, these mechanisms are usually bulky and difficult to adapt to the compact space requirements of modern machining equipment. Therefore, an independent face-changing tool mechanism is proposed to solve the problems mentioned above. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: An independent face-changing knife mechanism includes a support structure, the support structure including a support frame, a frame fixedly connected to the top of the support frame, and a protective shell fixedly connected to the outside of the frame. The top of the protective shell is fixedly connected to a feed hopper, the top of the frame is provided with a face-changing knife assembly, and the outside of the face-changing knife assembly is provided with a knife-changing mechanism. The face knife assembly includes a mounting bracket disposed on the top of the frame. Two face knife shafts are rotatably connected to one side inside the mounting bracket. Multiple face knives are fixedly connected to the outside of the face knife shafts. A synchronous gear is fixedly connected to one end of each of the two face knife shafts. A driven gear is fixedly installed at one end of one of the face knife shafts. The tool changing mechanism includes a drive motor disposed outside the mounting frame and a guide rail fixedly connected to the bottom of the mounting frame. A transmission wheel is fixedly connected to the output shaft of the drive motor. A transmission gear that meshes with a driven gear is fixedly connected to the outside of the transmission wheel. A slide is rotatably connected to the outside of the transmission gear. The slide is slidably connected to the outside of the guide rail. A traveling structure is provided on one side of the transmission wheel.

[0006] Furthermore, the mounting bracket is slidably connected to the top of the frame, the two sets of synchronous gears are meshed with each other, and the multiple face cutters are distributed at equal intervals on the outside of the face cutter shaft.

[0007] Furthermore, the number of face cutter shafts, face cutters, synchronizing gears, and driven gears are all multiple sets, and the multiple sets of face cutter shafts, face cutters, synchronizing gears, and driven gears are distributed at equal intervals inside the mounting frame.

[0008] Furthermore, the drive motor is fixedly installed on the outside of the frame, and the outer diameter of the slide is adapted to the inner diameter of the guide rail.

[0009] Furthermore, the walking structure includes a bevel gear distribution transmission box fixedly connected to the outside of the drive motor and a toothed plate fixedly connected to the outside of the mounting frame. The top of the bevel gear distribution transmission box is rotatably connected to a walking gear that meshes with the toothed plate, and a driven wheel is rotatably connected to one side of the outside of the bevel gear distribution transmission box.

[0010] Furthermore, the driven wheel and the transmission wheel are externally connected by a belt, and the traveling gear and the transmission gear rotate synchronously.

[0011] Furthermore, a connecting frame is fixedly connected to the outside of the support frame, and a conveyor belt is internally connected to the connecting frame.

[0012] Furthermore, a servo motor for driving the conveyor belt is fixedly installed on one side of the outside of the frame, and the conveyor belt is located on the lower surface of the feed hopper and the face knife assembly.

[0013] Compared with the prior art, this utility model provides an independent face-changing knife mechanism, which has the following beneficial effects: 1. This independent face-changing mechanism is started by a drive motor, which drives the transmission wheel and transmission gear to rotate via a belt. The transmission gear meshes with the driven gear, thereby driving the face-changing shaft to rotate, achieving axial rotation of the face-changing blade. At the same time, the power of the drive motor is transmitted to the traveling gear through a bevel gear distribution transmission box. The traveling gear meshes with the gear plate, causing the mounting bracket to slide on the guide rail, realizing radial replacement of the face-changing blade. This integrated operation of axial rotation and radial replacement of the face-changing blade reduces the number of motors and transmission components, making the blade changing action faster and more accurate, and greatly improving blade changing efficiency.

[0014] 2. This independent face-changing mechanism ensures the synchronous rotation of two sets of face-cutting shafts in opposite directions through the meshing transmission of synchronous gears, guaranteeing cutting accuracy. The sliding of the slide block and guide rail provides stable support for the transmission gears, preventing meshing misalignment. The meshing transmission of the traveling gear and the toothed plate, combined with the sliding connection between the mounting bracket and the frame, ensures smooth tool changing displacement, improving the stability and reliability of the equipment operation.

[0015] 3. This independent face-changing mechanism, by setting the face-cutting component and the conveyor belt to form an upper and lower linkage layout, the dough sheet conveyed by the feed hopper is cut by the face-cutting component and falls directly into the conveyor belt below. With the quick face-cutting capability of the face-cutting mechanism, the face-cutting component can be replaced without stopping the conveyor belt, avoiding production interruption in the traditional face-cutting process and further improving the overall production efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 5An independent face-changing knife mechanism in this embodiment includes a support structure 1. The support structure 1 includes a support frame 11, a frame 12 fixedly connected to the top of the support frame 11, and a protective shell 13 fixedly connected to the outside of the frame 12. The top of the protective shell 13 is fixedly connected to a feed hopper 2. A face-changing knife assembly 5 is provided on the top of the frame 12, and a knife-changing mechanism 6 is provided on the outside of the face-changing knife assembly 5. The face knife assembly 5 includes a mounting bracket 51 located on the top of the frame 12. Two face knife shafts 52 are rotatably connected to one side inside the mounting bracket 51. Multiple face knives 53 are fixedly connected to the outside of the face knife shafts 52. A synchronous gear 54 is fixedly connected to one end of each of the two face knife shafts 52. A driven gear 55 is fixedly installed at one end of one of the face knife shafts 52.

[0020] Specifically, the mounting frame 51 is slidably connected to the top of the frame 12, two sets of synchronous gears 54 mesh with each other, and multiple noodle blades 53 are distributed at equal intervals outside the noodle blade shaft 52. By setting the mounting frame 51 to slide with the frame 12, the displacement drive requirement of the blade changing mechanism 6 is met, allowing the noodle blade assembly 5 to move along the frame 12 to change blades, providing a basis for the subsequent movement of the walking structure. By setting the meshing of the two sets of synchronous gears 54, the synchronous rotation requirement of the noodle blade shaft 52 is met, ensuring that the cutting action is continuous and stable, and avoiding poor noodle forming quality due to different rotation speeds.

[0021] It should be noted that there are multiple sets of face cutter shaft 52, face cutter 53, synchronous gear 54 and driven gear 55, which are distributed at equal intervals inside the mounting frame 51.

[0022] In this embodiment, the tool changing mechanism 6 includes a drive motor 61 disposed outside the mounting frame 51 and a guide rail 62 fixedly connected to the bottom of the mounting frame 51. A transmission wheel 63 is fixedly connected to the output shaft of the drive motor 61. A transmission gear 64 that meshes with the driven gear 55 is fixedly connected to the outside of the transmission wheel 63. A slide 65 is rotatably connected to the outside of the transmission gear 64. The slide 65 is slidably connected to the outside of the guide rail 62. A walking structure is provided on one side of the transmission wheel 63.

[0023] The drive motor 61 is fixedly mounted on the outside of the frame 12, and the outer diameter of the slide 65 matches the inner diameter of the guide rail 62. When the drive motor 61 is working, it provides rotational power to the transmission wheel 63. The transmission wheel 63 not only receives the power from the drive motor 61, but also provides a power distribution basis for the transmission gear 64 and the walking structure. Through the meshing transmission of the transmission gear 64 and the driven gear 55, it receives the power demand of the face knife assembly 5 and drives the face knife shaft 52 to rotate. Through the sliding cooperation between the slide 65 and the guide rail 62, it receives the follow-up demand of the transmission gear 64, ensuring that the transmission gear 64 does not disengage when moving with the mounting frame 51, and at the same time provides stable guidance for the displacement of the driving mounting frame 51 by the walking structure.

[0024] Specifically, the traveling structure includes a bevel gear distribution transmission box 66 fixedly connected to the outside of the drive motor 61 and a toothed plate 610 fixedly connected to the outside of the mounting frame 51. A traveling gear 67, meshing with the toothed plate 610, is rotatably connected to the top of the bevel gear distribution transmission box 66. A driven wheel 68 is rotatably connected to one side of the outside of the bevel gear distribution transmission box 66. The bevel gear distribution transmission box 66 serves to distribute and transmit power, rationally allocating the power of the drive motor 61 to components such as the traveling gear 67. The meshing of the traveling gear 67 with the toothed plate 610 allows the mounting frame 51 to move. The driven wheel 68 assists in power transmission, effectively ensuring the positional movement of the mounting frame 51 by the tool changing mechanism 6.

[0025] It should be noted that the driven wheel 68 and the transmission wheel 63 are externally connected by a belt 69, and the traveling gear 67 and the transmission gear 64 rotate synchronously. The belt 69 transmission has advantages such as good flexibility and the ability to buffer and absorb vibration, reducing the impact and vibration during the transmission process and improving the smoothness of the transmission. The synchronous rotation of the traveling gear 67 and the transmission gear 64 ensures that the movement of the mounting bracket 51 and the rotation of the face cutter shaft 52 are coordinated and consistent, making the tool changing process more precise and efficient, and further improving the performance of the tool changing mechanism 6.

[0026] In this embodiment, a connecting frame 3 is fixedly connected to the outside of the support frame 11, and a conveyor belt 4 is driven internally connected to the connecting frame 3. A servo motor 7 for driving the conveyor belt 4 is fixedly installed on one side of the outside of the frame 12. The conveyor belt 4 is located on the lower surface of the feed hopper 2 and the face knife assembly 5.

[0027] The working principle of the above embodiments is as follows: In actual operation, the dough sheet material is first fed into the feed hopper 2, and the servo motor 7 drives the conveyor belt 4 to transport the dough sheet to the bottom of the noodle cutter assembly 5. When different specifications of noodles need to be produced, the drive motor 61 starts working, and transmits power to the transmission gear 64 and the walking structure through the transmission wheel 63. The transmission gear 64 meshes with the driven gear 55, driving the noodle cutter shaft 52 to rotate. At the same time, the bevel gear distribution transmission box 66 distributes power to the walking gear 67, which meshes with the toothed plate 610, causing the mounting frame 51 to move on the frame 12. The slide 65 slides on the guide rail 62, ensuring that the transmission gear 64 does not disengage when moving with the mounting frame 51. The driven wheel 68 and the transmission wheel 63 are driven by the belt 69 to ensure that the walking gear 67 and the transmission gear 64 rotate synchronously, so that the movement of the mounting frame 51 and the rotation of the noodle cutter shaft 52 are coordinated, thereby achieving fast and accurate cutter changing operation. After the cutter is changed, the noodle cutter assembly 5 continues to cut the dough sheet to produce noodles that meet the requirements.

Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply.
