Abstract
Description
Technical Field
[0001] This utility model belongs to the field of onion processing technology, and more specifically, it relates to an onion stem and root removal cutting device. Background Technology
[0002] When cutting onions, it is usually necessary to first remove the stems and roots at both ends to remove the inedible parts and facilitate subsequent cutting. In order to improve efficiency, ensure neat cut surfaces, and reduce the irritation to the eyes caused by the irritating gases released by the onions during the cutting process, operators often need to use special onion cutting devices.
[0003] According to application number CN202223512576.5, an onion root-removing and peeling device includes a main body. A first through-hole is formed at the top of the main body, and a carrier body is located at the first through-hole. A first motor is located at the top of the main body. A reciprocating screw is located inside the main body, extending to the top of the main body and fixedly connected to the output shaft of the first motor. A sorting bin is located at the bottom of the main body. This invention works by having the onion pass through the receiving through-hole of the carrier plate. The smaller bottom end of the onion passes through an elastic block, while the root end of the onion is connected to the bottom end of the elastic block. At this time, the reciprocating screw drives a first gear to rotate, which in turn drives a second gear. The second gear drives a cutter to rotate. When the cutter rotates into the infeed groove of the carrier plate, it cuts the root of the onion, thus removing the root and peeling the onion. The pressing plate continues to carry the onion past the elastic block, and the sorting bin separates the onion from its peel and root.
[0004] Based on the above, existing onion cutting devices often fail to accurately adapt to different sizes of onions due to individual differences in onion size. This can lead to situations where too much or too little is cut off when removing the root and top, resulting in food waste and potentially affecting the uniformity of subsequent processing and the quality of the final product. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides an onion stem and root removal cutting device. This addresses the issue that existing onion cutting devices often fail to accurately adapt to different onion sizes due to individual differences in onion dimensions. Consequently, they may end up removing too much or too little of the root and top, resulting in food waste and potentially affecting the uniformity of subsequent processing and the quality of the final product.
[0006] The purpose and effect of this utility model's onion stem and root removal cutting device are achieved by the following specific technical means: An onion stem and root removal cutting device includes a body, a fixed frame, support legs, a transmission assembly, a fixed box, an electric push rod, an adaptation mechanism, and a cutting mechanism. The fixed frame is fixedly connected to the outside of the body. Two support legs are provided, each fixedly connected to the lower end face of the front end of the fixed frame. The transmission assembly is installed inside the fixed frame. Multiple fixed boxes are provided, each fixedly connected to the outside of the transmission assembly. The electric push rod is fixedly installed inside the body. The adaptation mechanism is located inside the fixed box. The cutting mechanism is located inside the body.
[0007] Furthermore, the adaptation mechanism includes: a sliding plate, a compression spring, and a support clamp; the sliding plate is provided in multiple sets, and each set of sliding plates is slidably connected to the inner side of multiple fixed boxes; the compression spring is provided in multiple sets, with one end of each set of compression springs fixedly connected to the outer side of the multiple sets of sliding plates, and the other end of each set of compression springs fixedly connected to the inner side of the multiple fixed boxes; the support clamp is provided in multiple sets, and each set of support clamps is fixedly connected to the outer side of the multiple sets of sliding plates.
[0008] Furthermore, the adaptation mechanism also includes: a fixed rack and connecting gears; the fixed rack is provided in multiple sets, and the multiple sets of fixed racks are respectively fixedly connected to the outside of multiple sets of sliding plates; the connecting gear is provided in multiple sets, and the multiple connecting gears are respectively rotatably connected to the inside of multiple fixed boxes, and the multiple connecting gears respectively mesh with the multiple sets of fixed racks.
[0009] Furthermore, the adaptation mechanism also includes: positioning grooves, positioning balls, and positioning springs; the positioning grooves are provided in multiple sets, and the multiple sets of positioning grooves are respectively opened on the inner side of multiple fixed boxes; the positioning balls are provided in multiple sets, and the multiple sets of positioning balls are respectively slidably connected to the inner side of multiple sets of sliding plates; the positioning springs are provided in multiple sets, one end of the multiple sets of positioning springs is respectively fixedly connected to the outer side of the multiple sets of positioning balls, and the other end of the multiple sets of positioning springs is respectively fixedly connected to the inner side of the multiple sets of sliding plates.
[0010] Furthermore, the cutting mechanism includes: a connecting box, an adjusting plate, a cutting blade, and a tension spring; the connecting box is fixedly connected to the lower end of the telescopic shaft of the electric push rod; there are two adjusting plates, both of which are slidably connected to the inner side of the connecting box; there are two cutting blades, each fixedly connected to the outer side of one of the two adjusting plates; and there are two tension springs, each fixedly connected to the inner side of one of the two cutting blades.
[0011] Furthermore, the cutting mechanism also includes: a fixed rod, a sliding rod, and an adjusting rod; the fixed rod is provided in two sets, and the two sets of fixed rods are respectively fixedly connected to the outside of the two cutting blades; the sliding rod is provided in two sets, and the two sets of sliding rods are respectively slidably connected to the inside of the two sets of fixed rods; the adjusting rod is provided in two sets, and the two adjusting rods are respectively fixedly connected to the lower end of the two sets of sliding rods.
[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention, through its adaptive mechanism, enables the clamping and positioning of onions of different sizes. The onion is placed inside two supporting clamps; by pressing down on the onion, the clamps slide outwards according to its size, exposing only the stem and root of the onion. The matching design of the positioning groove and positioning ball ensures a stable position when the onion is held within the clamps, preventing the clamps from retracting on their own. When the onion is removed, the supporting clamps automatically return to their original position under the action of a compression spring, effectively improving the device's adaptability to onions of different sizes. Furthermore, the cutting mechanism enables the cutting of onions of different sizes. When the transmission assembly is activated, it drives the fixed box and support clamp to slide. When the support clamp enters the inner side of the adjusting rod, the adjusting rod moves accordingly based on the position of the clamp. This, in turn, links the cutting blade with the sliding rod and the fixed rod, allowing the cutting blade to adaptively cut according to the actual size of the onion. This design not only improves the applicability of the equipment and reduces food waste, but also effectively ensures the consistency of cutting and product quality. Through the above mechanism, the clamping and positioning of onions of different sizes are achieved, while adaptive cutting is completed, significantly improving the adaptability of the equipment, saving raw materials, and ensuring processing quality.
