Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, and specifically relates to a potato wedge cutter. Background Technology

[0002] In the food processing industry, potato wedges are a common food form, widely used in fast food restaurants, restaurants, and home cooking. Traditional potato wedge cutting mainly relies on manual cutting with a knife. This method is not only inefficient, but also results in inconsistent wedge shapes and sizes, affecting the appearance and cooking results. With the increasing mechanization of food processing, various potato cutting devices have emerged on the market. However, existing wedge cutters generally suffer from complex structures and cumbersome operation. Most existing potato wedge cutters use a reciprocating cutting method, requiring multiple operations to complete the wedge cutting of a single potato, resulting in low efficiency. Some devices use a rotary cutting method, but due to the lack of an effective potato fixing device, the potato is prone to slipping or rotating during cutting, leading to cutting failures or uneven cuts. Existing fixing devices mostly use clamping methods, but the clamping force is difficult to control; too much force damages the potato, while too little force fails to secure it effectively. The cutting blade layout in existing technologies is unreasonable, preventing multi-angle cuts in one operation and requiring multiple cuts by adjusting the potato position, increasing operational complexity. Some devices have improperly designed guide systems, causing unstable movement trajectories of the pressing plate during cutting, affecting cutting accuracy. There is a lack of effective potato wedge collection devices in the current technology, and manual collection is required after cutting, which reduces the overall operation efficiency.

[0046] The following is another specific embodiment 2 of this utility model: Embodiment 2 is an optimization and improvement of the cutting blade assembly based on Embodiment 1. In this embodiment, the number of V-shaped cutting blades is increased to 10, and the blade material is changed to 440C stainless steel, which has higher hardness and wear resistance. The length of each V-shaped cutting blade is adjusted to 70 mm, while the thickness remains unchanged at 3 mm. However, the cross-sectional shape of the blade is optimized to a wedge design, with a back thickness of 3 mm and an edge thickness reduced to 0.5 mm, improving cutting sharpness. The blade holder is correspondingly adjusted to accommodate 10 blades, with its diameter increased to 140 mm and the number of mounting slots increased to 10, with an angular interval of 36 degrees between each slot. To accommodate the increased number of blades, the diameter of the pressing plate is correspondingly adjusted to 130 mm, and the number of concentric annular protrusions on the lower surface is increased to 4, with the protrusion spacing adjusted to 12 mm. The number of radial grooves in the base groove area is correspondingly increased to 10, consistent with the distribution of the cutting blades. The length of the connecting rod is adjusted to 220 mm to accommodate the increased operating space requirements. This improvement increases the number of potato wedges that can be cut, and the shapes are more precise, making it suitable for applications with high requirements for potato wedge specifications. The improved wedge cutter maintains its original ease of operation while enhancing cutting accuracy and product quality, meeting higher standards of food processing.

[0047] The following is another specific embodiment 3 of this utility model: Embodiment 3 is based on Embodiment 1, with optimizations and improvements to the guiding device and pressing mechanism.

The center distance between the two guide columns is 80 mm, and each guide column has a diameter of 15 mm and a height of 120 mm. Correspondingly, the connecting rod is changed to a double-rod structure, with two connecting rods arranged parallel to each other, a rod spacing of 80 mm, and each connecting rod having a diameter of 10 mm. Two guide sleeve mounting holes are correspondingly opened on the pressing plate, with one guide sleeve installed in each hole. The guide sleeve has an inner diameter of 15.5 mm and an outer diameter of 20 mm. The double guide column structure significantly improves the stability of the pressing plate's movement, eliminating lateral swaying and rotational tendencies. The pressing mechanism adds a handle design, with a horizontal handle at the upper end of the double connecting rods. The handle is 120 mm long and covered with rubber material to improve grip comfort. The return springs have been changed to a dual-spring configuration, with one return spring on each connecting rod. The spring parameters are the same as in Example 1, and the symmetrical configuration of the dual springs ensures a uniform distribution of the return force. The collection trough has been moved to the left side of the base, increasing its volume by 20%, which facilitates the collection of potato wedges during large-scale operations. This improvement significantly enhances the operational stability and user comfort of the equipment, making it particularly suitable for commercial applications requiring long-term continuous operation.

[0048] Specifically, the principle of this invention is as follows: This invention employs a radially distributed V-shaped cutting blade assembly structure, utilizing geometric principles to achieve simultaneous multi-angle cutting of potatoes. The 60-degree angle design of the V-shaped cutting blades is based on the optimal shape requirements of potato corners, ensuring that the cut potato corners have good cooking adaptability. Multiple blades are radially distributed, with their tips pointing towards the geometric center of the groove area. When the potato is placed in the center of the groove area, each blade forms a uniform cutting angle with the potato surface, achieving simultaneous cutting. The pressing mechanism presses the potato against the cutting blade assembly through vertical downward pressure, utilizing the sharpness of the blades and the pressing force to achieve fast and clean cutting. The guiding device adopts a sliding guiding principle to ensure the precise vertical movement of the pressing plate and avoid the impact of lateral deviation on cutting accuracy. The elliptical design of the base groove area conforms to the natural shape characteristics of the potato, and the radial concave texture utilizes the principle of friction to increase the contact stability between the potato and the base. The return spring utilizes the principle of storing and releasing elastic potential energy to achieve automatic reset of the pressing plate, reducing manual operation. The trapezoidal design of the collection trough utilizes the principle of gravity, allowing the cut potato wedges to slide naturally to the collection position, improving collection efficiency. The overall design follows the principles of mechanical transmission and mechanical balance, ensuring that all components work in coordination to achieve efficient and stable cutting results.
