Ultrasonic Candy and Cake Cutting Machine Design Scheme
This scheme aims to design an ultrasonic cutting machine suitable for various types of candy and cakes, capable of precisely processing rectangular sponge cream cakes, rectangular wafers, rectangular toffee blocks, and round sponge cream cakes. The core of the equipment utilizes a continuous conveyor belt structure for continuous material transport, coupled with a control system that allows for flexible parameter adjustment, ensuring that the cutting size is adjustable as needed, balancing cutting accuracy and production efficiency, and meeting the standardization and flexibility requirements of food processing.
Overall Design Architecture
The equipment follows a continuous operation process of “conveyance-positioning-cutting-output.” The main structure consists of a continuous conveyor belt unit, an ultrasonic cutting unit, a positioning and guiding unit, a control system unit, and a frame protection unit. The frame is made of 304 stainless steel, ensuring structural stability and meeting food processing hygiene standards to prevent material contamination.
The continuous conveyor belt runs through the entire equipment. The inlet and outlet ends are horizontally aligned. A material guide plate is installed at the inlet end to ensure that rectangular and round materials enter the cutting area smoothly; the outlet end is equipped with a finished product guide trough for easy collection of cut materials and connection to subsequent processes. The conveyor belt is designed with a width of 600mm to accommodate cake materials of different sizes. The conveyor belt speed is adjustable via frequency conversion, ranging from 0.5-3m/min, allowing for flexible matching based on cutting precision requirements and material characteristics.
Core Control System Design
The control system is based on a programmable logic controller (PLC) with a touchscreen interface, enabling convenient adjustment of cutting dimensions and real-time monitoring of equipment operation status, meeting the cutting parameter adaptation needs of various material types.
The cutting dimension adjustment function is achieved through dual parameter settings: firstly, lateral cutting spacing adjustment, driven by a servo motor to move the cutting blade holder laterally. The target spacing value (range 5-100mm) is input on the touchscreen, and the PLC controls the servo motor for precise positioning, with an error controlled within ±0.5mm; secondly, longitudinal cutting length adjustment, achieved through the coordinated control of the conveyor belt speed and cutting trigger signal. Setting the material conveying distance completes the longitudinal dimension setting, supporting arbitrary adjustment within the range of 50-500mm. For round sponge cream cakes, the system has a built-in round cutting mode, allowing direct input of diameter parameters (30-200mm) for automatic matching of the cutting trajectory.
The system also features parameter memory, storing cutting parameters for 10 different materials. These parameters can be directly recalled when switching material types, eliminating the need for repeated settings. It is also equipped with a fault alarm module; in case of material misalignment or cutter malfunction, an audible and visual alarm is immediately triggered, and the machine stops, ensuring operational safety.
Key Component Design
1. Ultrasonic Cutting Unit
The cutting unit uses a 20kHz high-frequency ultrasonic generator with an adjustable output power ranging from 500-1500W, adapting to materials of varying hardness: low power is used for soft sponge cakes to prevent material deformation due to compression; higher power ensures smooth cutting for harder toffee blocks. The cutting head is made of titanium alloy with a specially polished blade to reduce material adhesion, and a cooling device prevents high temperatures from affecting material quality. The cutting blade holder uses a lifting structure, allowing adjustment of the blade height according to material thickness (5-100mm) to accommodate different cake sizes.
2. Positioning and Guiding Unit
To ensure cutting accuracy, two positioning mechanisms are installed in front of the cutting area: Lateral positioning uses adjustable guards, with the spacing manually adjusted according to the material width. Silicone pads are attached to the inside of the guards to prevent scratching the material. Longitudinal positioning uses photoelectric sensors to detect the front position of the material in real time, triggering a cutting signal to ensure precise longitudinal cutting dimensions. For round materials, an additional centering mechanism is added, using symmetrical rollers to center the round cake, ensuring the coaxiality of the circular cutting trajectory.
3. Through-type Conveyor Belt Unit
The conveyor belt is made of food-grade polyurethane material with anti-slip textured surfaces to prevent material deviation during transport. It is also wear-resistant and easy to clean, meeting food processing hygiene requirements. The conveyor belt is driven by a geared motor with a frequency converter for smooth speed regulation. Removable protective baffles are installed on both sides of the conveyor belt for easy cleaning and maintenance. The baffle height is adjustable according to the material height to prevent material from falling.
Safety and Operation Design
The equipment is equipped with a fully enclosed protective cover, with openings only at the inlet and outlet ends to prevent debris from splashing during ultrasonic cutting and to prevent operators from contacting moving parts. The protective cover is made of transparent acrylic material for easy observation of the operating status. The operating area is equipped with an emergency stop button and a start/pause button. The operating procedure is simple and easy to understand; ordinary operators can be trained and put into operation quickly.
Adjustable support feet are provided at the bottom of the equipment, which can be adjusted according to the flatness of the workshop floor to ensure stable operation. A cleaning passage is also provided, and the conveyor belt can be quickly disassembled for convenient daily cleaning and disinfection, meeting food production hygiene standards.
Equipment Advantages and Applicable Scenarios
This equipment, through its adjustable control system and highly adaptable cutting unit, achieves precise cutting of various types of candies and cakes. The through-type conveyor belt design significantly improves production efficiency, making it suitable for batch production in small and medium-sized food processing plants. The equipment boasts a compact overall structure and a small footprint (approximately 2.5m × 1.2m × 1.8m), allowing for flexible integration into existing production lines. It is also characterized by ease of operation and low maintenance costs, effectively reducing the production and operating costs for businesses.
In summary, this ultrasonic candy and cake cutting machine, through its rational structural design, precise control system, and highly adaptable key components, fully meets the cutting needs of various candies and cakes, including rectangular and round shapes. The cutting size is adjustable, and the conveying process is continuous, complying with the standardization and safety requirements of food processing.
