Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing technology, and in particular to an adjustment mechanism for adjusting the cutting length of a vegetable cutter. Background Technology
[0002] A food cutter is a food processing machine that uses a blade structure to cut ingredients. Based on the usage scenario, it is divided into commercial and household types. Common types include slicers, shredders, and dicers.
[0003] In food processing, vegetable cutters are key equipment for improving efficiency. The accuracy of their cutting length directly affects the processing quality of ingredients and the subsequent cooking effect. Existing vegetable cutter length adjustment mechanisms mostly use manual knobs and scales, which rely on the operator's experience and are prone to errors of ±2mm or more. In addition, they lack a buffer component for the blade, and the blade makes hard contact with the worktable, which can easily cause blade wear and equipment vibration, making them impractical. Therefore, it is necessary to redesign a vegetable cutter length adjustment mechanism to address the above problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustment mechanism for adjusting the cutting length of a vegetable cutter.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustment mechanism for adjusting the cutting length of a vegetable cutter includes a frame. A support frame is fixedly installed on the bottom wall of the frame. Multiple guide rollers are rotatably installed on the upper surface of the frame via a conveyor frame. An installation frame is fixedly installed on the upper surface of the conveyor frame via a first support frame. A pressing frame is fixedly connected inside the installation frame via a pressing mechanism. A pressure roller is rotatably installed inside the pressing frame. A screw is rotatably installed on the outer wall of the conveyor frame via a moving frame. A servo motor connected to the screw is fixedly installed on the outer wall of the moving frame. A moving block is rotatably installed on the outer wall of the screw via a thread. A limit rod is fixedly installed inside the moving frame and slides through the moving block. A connecting rod is fixedly installed on the upper surface of the moving block. A push plate is fixedly connected to the outer wall of the connecting rod via a fixing mechanism. A cylinder is fixedly installed on the upper surface of the frame via a second support frame. A telescopic opening that mates with the telescopic end of the cylinder is opened on the upper surface of the second support frame. A blade is fixedly installed on the telescopic end of the cylinder via a fixing frame.
[0006] The pressing mechanism includes a servo electric actuator fixedly installed inside the mounting frame. The upper surface of the mounting frame has a lifting opening that cooperates with the telescopic end of the servo electric actuator. The telescopic end of the servo electric actuator is fixedly connected to the upper surface of the pressing frame.
[0007] Preferably, the fixing mechanism includes two fixing rods fixedly installed on the outer wall of the connecting rod, and the ends of the two fixing rods are fixedly connected to the outer wall of the push plate.
[0008] Preferably, a guide rod is fixedly installed on the outer wall of the fixed frame, and a guide opening that cooperates with the guide rod is opened on the outer wall of the second support frame.
[0009] Preferably, a spring telescopic rod is fixedly installed on the upper end face of the frame, and a buffer plate that cooperates with the cutting tool is fixedly installed on the telescopic end of the spring telescopic rod.
[0010] Preferably, a guide frame is fixedly installed at the end of the frame, and a collection box that cooperates with the guide frame is slidably installed on the outer wall of the support frame through a connecting frame.
[0011] Preferably, a controller is fixedly mounted on the bottom wall of the frame via a mounting plate, and the controller is electrically connected to the servo electric actuator, the servo motor, and the cylinder.
[0012] The beneficial effects of this utility model are: 1. By setting up components such as a screw, servo motor, limit rod, moving block and push plate, the servo motor drives the screw to rotate, and with the limit rod guiding, the push plate is driven to adjust smoothly and accurately. This avoids the problems of traditional manual adjustment that rely on experience and are prone to deviation. The controller directly controls the adjustment, eliminating the need for manual disassembly and debugging. Simply input the preset length to automatically adjust, reduce errors, improve cutting consistency and meet standardization requirements.
[0013] 2. By setting up components such as guide rods, spring telescopic rods and buffer plates, when the cylinder drives the cutter to rise and fall, the guide rods cooperate with the guide opening to limit the movement, preventing the cutter from tilting and ensuring a flat cutting surface. The spring telescopic rods and buffer plates provide elastic buffering, avoiding hard contact, reducing cutter wear and equipment vibration, extending service life, reducing noise, and improving equipment stability and durability.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Reference Figure 1-6 An adjustment mechanism for adjusting the cutting length of a vegetable cutter includes a frame 1, a support frame 2 fixedly mounted on the bottom wall of the frame 1, multiple guide rollers 4 rotatably mounted on the upper surface of the frame 1 via a conveyor frame 3, an mounting frame 6 fixedly mounted on the upper surface of the conveyor frame 3 via a first support frame 5, a pressing frame 8 fixedly connected inside the mounting frame 6 via a pressing mechanism, a pressure roller 9 rotatably mounted inside the pressing frame 8, a screw 11 rotatably mounted on the outer wall of the conveyor frame 3 via a moving frame 10, and a servo motor 12 connected to the screw 11 fixedly mounted on the outer wall of the moving frame 10. A movable block 14 is rotatably mounted on the outer wall of the screw 11. A limit rod 13 is fixedly mounted inside the movable frame 10. The limit rod 13 slides through the movable block 14. A connecting rod 15 is fixedly mounted on the upper end face of the movable block 14. A push plate 17 is fixedly connected to the outer wall of the connecting rod 15 through a fixing mechanism. A cylinder 19 is fixedly mounted on the upper end face of the frame 1 through a second support frame 18. A telescopic opening that cooperates with the telescopic end of the cylinder 19 is opened on the upper end face of the second support frame 18. A cutter 21 is fixedly mounted on the telescopic end of the cylinder 19 through a fixing frame 20.
[0018] Furthermore, the frame 1 provides a stable mounting base for each component, the support frame 2 can enhance the stability of the overall mechanism when it is placed, the guide roller 4 is used to carry the food and work with the push plate 17 to realize the food conveying, the pressure roller 9 can press the food during the food conveying process to prevent the food from shifting, and the blade 21 is used to complete the food cutting action.
[0019] The pressing mechanism includes a servo electric actuator 7 fixedly installed inside the mounting frame 6. The upper surface of the mounting frame 6 has a lifting opening that cooperates with the telescopic end of the servo electric actuator 7. The telescopic end of the servo electric actuator 7 is fixedly connected to the upper surface of the pressing frame 8.
[0020] Furthermore, the servo electric actuator 7 serves as the power source for the pressing mechanism. It can drive the pressing frame 8 to move up and down through telescopic movements, thereby adjusting the height of the pressing roller 9 to accommodate ingredients of different thicknesses. The lifting opening provides space for the movement of the telescopic end of the servo electric actuator 7, avoiding interference with the mounting frame 6.
[0021] The fixing mechanism includes two fixing rods 16 fixedly installed on the outer wall of the connecting rod 15, and the ends of the two fixing rods 16 are fixedly connected to the outer wall of the push plate 17.
[0022] Furthermore, two fixing rods 16 are symmetrically distributed on both sides of the connecting rod 15, which can enhance the firmness of the connection between the push plate 17 and the connecting rod 15, prevent the push plate 17 from loosening or shifting during the process of pushing the food, and ensure that the push plate 17 can stably drive the food to move.
[0023] A guide rod 22 is fixedly installed on the outer wall of the fixed frame 20, and a guide opening that cooperates with the guide rod 22 is opened on the outer wall of the second support frame 18.
[0024] Furthermore, the guide rod 22 moves synchronously with the fixed frame 20, and the guide opening restricts the movement trajectory of the guide rod 22, which can prevent tilting when the cylinder 19 drives the tool 21 to rise and fall, ensuring that the tool 21 always moves in the vertical direction and improving the flatness of the cut.
[0025] A spring telescopic rod 23 is fixedly installed on the upper end face of the frame 1, and a buffer plate 24 that cooperates with the cutter 21 is fixedly installed on the telescopic end of the spring telescopic rod 23.
[0026] Furthermore, the buffer plate 24 is located directly below the blade 21, and can cooperate with the blade 21 when cutting food. The spring telescopic rod 23 can provide elastic cushioning when the blade 21 contacts the buffer plate 24, avoiding hard contact between the blade 21 and the frame 1 and causing wear.
[0027] A guide frame 25 is fixedly installed at the end of the frame 1, and a collection box 27 that cooperates with the guide frame 25 is slidably installed on the outer wall of the support frame 2 through the connecting frame 26.
[0028] Furthermore, the guide frame 25 can guide the cut ingredients to fall smoothly and prevent them from scattering. The connecting frame 26 provides installation support for the collection box 27, which is used to collect the cut ingredients. The sliding installation method makes it easy to remove and clean them later.
[0029] The bottom wall of the frame 1 is fixedly mounted with a controller 28 via a mounting plate. The controller 28 is electrically connected to the servo electric actuator 7, the servo motor 12, and the cylinder 19.
[0030] Furthermore, the controller 28 can uniformly control the working status of the servo electric actuator 7, the servo motor 12 and the cylinder 19, realizing the coordinated operation of each component without the need for manual operation of each component, thus improving the convenience and automation of the mechanism.
[0031] When this utility model is in use, the cylinder 19 can be driven by an external air source. When the external air source supplies air to the cylinder 19, the telescopic end of the cylinder 19 can extend and retract along the telescopic opening of the second support frame 18, thereby driving the fixed frame 20 and the knife 21 to rise and fall synchronously. The guide rod 22 on the outer wall of the fixed frame 20 moves with the fixed frame 20 and slides along the guide opening of the second support frame 18 to limit the lifting direction of the knife 21, ensuring that the knife 21 always moves in the vertical direction. After the food is placed on the guide roller 4, the controller 28 controls the servo motor 12 to start. The servo motor 12 drives the screw 11 to rotate. The moving block 14 moves along the moving frame 10 under the action of the screw 11 and the limiting rod 13. Through the connecting rod 15 and the fixed rod 16, the push plate 17 moves towards the direction of the knife 21. The push plate 17 pushes the food to move synchronously. The guide roller 4 is passively rotated under the action of the food, realizing the pushing of the food. When the food moves below the pressure roller 9, the controller 28 controls the servo electric actuator 7 to drive the lower pressure frame 8 and the pressure roller 9 to descend, so that the pressure roller 9 contacts the upper surface of the food. This, combined with the guide roller 4, presses the food firmly, preventing it from shifting during subsequent movement. The pressure roller 9 rotates passively as the food moves. When one end of the food contacts the push plate 17 and continues to be pushed to the corresponding position below the cutter 21, the controller 28 controls the push plate 17 to stop moving and simultaneously controls the cylinder 19 to drive the cutter 21 to descend. During the descent, the cutter 21, in conjunction with the buffer plate 24, completes the pressing of the food. During the cutting process, the spring telescopic rod 23 extends and retracts when the cutter 21 contacts the buffer plate 24, which buffers the cutter 21. After the cutting is completed, the cylinder 19 drives the cutter 21 to rise and reset, the servo electric push rod 7 drives the pressure roller 9 to rise and reset, the push plate 17 continues to push the remaining food to move, and the guide roller 4 continues to rotate passively with the food. The above cutting process is repeated. The cut food is conveyed to the end of the frame 1 through the guide roller 4 and falls into the collection box 27 through the guide frame 25. The collection box 27 can slide horizontally along the connecting frame 26 for easy removal and cleaning.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
