Description

Technical Field

[0001] This utility model relates to the field of vegetable processing, and in particular to a cutting device for pickling green beans. Background Technology

[0002] In the pickling process of green beans, the raw materials need to be cut into uniformly long segments to improve pickling efficiency and finished product quality. Current technologies suffer from low efficiency, high labor intensity, and inconsistent cut lengths when using manual cutting. Mechanized cutting equipment often uses a single feeding channel and fixed-spaced rollers to align the green beans, which can easily lead to misalignment or blade breakage due to differences in bean diameter. Furthermore, existing equipment generally lacks a raw material pretreatment module, allowing impurities such as mud, sand, and broken leaves carried by the green beans to directly enter the cutting process, affecting the hygiene and quality of the pickling process.

[0003] The vegetable slicing device disclosed in Chinese patent CN218195598U, through the setting of a slicing mechanism, facilitates the adjustment of the slicing length to meet different processing needs; through the setting of a feeding mechanism, it facilitates the unloading of slicing vegetables and makes it easy to control the slicing length, thereby improving processing efficiency. However, it lacks an anti-slip structure, and the vegetables are prone to slipping and deviating during transportation. Therefore, there is an urgent need for a bean slicing device with efficient cleaning, precise alignment, and adaptive slicing functions. Utility Model Content

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] In the attached diagram, all identical reference numerals refer to the same components.

[0026] Example 1: As Figure 1-5 As shown, this utility model provides a cutting device for pickling green beans, including a lifting and feeding assembly 1, a vibrating feeding assembly 2, a cutting assembly 3, and a linkage controller 4.

[0027] Lifting and feeding assembly 1: The power drive device 11 adopts a hydraulic lift, with its bottom fixed to the ground by bolts and its top connected to a tiltable feeding hopper 12. The feeding hopper 12 is made of stainless steel, with a hopper opening width of 800mm, and its sidewalls are connected to the lifting platform via hinges. A weighing sensor 112 is embedded above the lifting platform to monitor the weight of the material in real time. When the weight reaches 100kg, the tilting mechanism 113 is triggered, driving the feeding hopper 12 to rotate 90° around the hinge axis, tilting the green beans onto the vibrating table 21 of the vibrating feeding assembly 2.

[0028] Vibrating Feeding Assembly 2: The vibrating table 21 is installed at a 15° angle, connected to the frame at the bottom by springs, and driven by a variable frequency motor 211 to generate high-frequency vibration. A vibrating screen 22, made of 304 stainless steel perforated plate with 10mm aperture, is laid on the surface of the vibrating table 21 to filter out mud and sand impurities. The vibrating guide plate 23 is a V-shaped guide channel welded to the surface of the screen 22, with an inlet width of 80mm and an outlet width of 30mm, guiding the beans to arrange in a single layer along the inclined surface. Impurities fall through the screen 22 into a detachable impurity collection hopper 24 at the bottom, which is connected to the frame by clips for easy cleaning.

[0029] Slitting assembly 3: The feeding roller group 31 includes three sets of nylon rollers with diameters of Φ50mm, Φ40mm, and Φ30mm, respectively, with the spacing between adjacent rollers decreasing from 15mm to 5mm. The roller surfaces are provided with serrated anti-slip protrusions 311, with a protrusion density increasing from 8 to 12 per cm², used to gradually align the green beans along the axial direction. The cutting blade 322 of the cutting blade assembly 32 is connected to the servo motor 321 via a coupling. Guide plates 323 are installed on both sides of the blade 322, sliding along the guide rail 324 to ensure a vertical cutting trajectory. The linkage controller 4 receives encoder signals from the feeding roller group 31 and dynamically adjusts the speed of the servo motor 321 to match the cutting frequency with the green bean conveying speed.

[0030] Example 2: Based on Example 1, this example further optimizes the adjustment function of the material distribution roller assembly 31: The material distribution roller assembly 31 is equipped with a lifting mechanism 33, including a screw lifting module 331 and a height scale 332. The screw lifting module 331 is driven by a handwheel to move the roller support up and down with a movement accuracy of ±0.05mm; the height scale 332 is engraved on the side of the frame with a scale interval of 0.5mm for intuitive reading of the roller spacing.

[0031] When processing green beans with a larger diameter, manually rotate the screw lifting module 331 to adjust the roller spacing from 5mm to 8mm. The linkage controller 4 simultaneously increases the cutting frequency by 15% to ensure that the cutting length error is ≤±2%.

[0032] The method of using this utility model is as follows:

[0033] 1. The power drive device 11 of the lifting and feeding assembly 1 is vertically lifted;

[0034] 2. The vibrating guide plates 23 of the vibrating feeding assembly 2 are oriented.

[0035] 3. The material distribution roller group 31 of the slitting component 3 is axially aligned;

[0036] 4. The cutting blade assembly 32 performs closed-loop cutting, forming a continuous processing chain. The increasing density of the anti-slip protrusions 311 and the decreasing roller spacing work together to solve the problems of green beans slipping and stacking.

[0037] Furthermore, the weighing sensor 112 triggers the flipping mechanism 113 to achieve quantitative feeding and avoid manual handling.

[0038] Furthermore, the vibrating screen 22 works in conjunction with the guide plate 23 to complete the filtration of impurities and the single-layer feeding of green beans.

[0039] Furthermore, the linkage controller 4 adjusts the cutting frequency in real time according to the conveying speed to ensure consistent length.

[0040] Furthermore, the lifting mechanism 33 can be replaced with an electric push rod, which automatically adjusts the roller spacing through the linkage controller 4, making it suitable for batch processing of continuously variable diameter green beans.

[0041] Furthermore, a laser sensor can be added to the guide rail 324 to detect the wear status of the blade 322 and trigger an alarm.

[0042] This utility model is a cutting device for pickling green beans, which is suitable for pickling food factories, pickle processing lines and other scenarios, and can process long vegetables such as cowpeas and green beans.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
