Automatic spiral stem stripping device for preserved vegetable

Abstract

This invention discloses an automated spiral stem-removing device for pickling mustard tubers, comprising a frame structure, including a base frame, with a vertical plate fixed to the top surface of one end of the base frame. A processing mechanism is provided on the side wall of the vertical plate. The position adjustment structure achieves overall horizontal and vertical coarse-to-fine adjustment of the processing mechanism through dual servo screws. Then, in conjunction with the diameter-changing effect of the segmented spiral blade structure, it realizes the adjustment of the cutting position according to the feeding state of the mustard tuber head. It not only adjusts the position but also changes the diameter to ensure accurate cutting. The segmented spiral blade structure adopts a closed-loop constraint structure with an inner diameter-changing blade for conformal cutting and an outer guide structure with elastic rollers for circumferential restraint. The extrusion roller of the guide structure relies on a second torsion spring to form radial floating compensation, flexibly lifting and limiting the workpiece from multiple points on the outer periphery, offsetting the lateral thrust generated by the spiral blade cutting, and constraining the mustard tuber head to keep it coaxial and centered throughout the feeding process, thus avoiding jamming and material jamming.

Description

Technical Field

[0001] This invention relates to the field of pickled mustard tuber production technology, specifically to an automated spiral stem-removing device for pickling pickled mustard tubers. Background Technology

[0002] In the pickling process of pickled mustard tuber, "stem removal," also known as "removing tendons / vein stripping," is a crucial trimming step that removes the tough outer skin, hard tendons, and coarse fibers from the surface of the mustard tuber head (stem mustard), leaving only the crisp and tender flesh. This process directly affects the taste and appearance of the finished product. Currently, stem removal is mostly done manually, using a small knife to first peel off the outer rough and tough skin, then removing the obviously protruding hard tendons and coarse fibers. The crevices are gently picked with the tip of the knife to remove impurities and tough tendons, preserving the tender green skin and crisp flesh. This process is inefficient and relies heavily on worker skill. With development, manufacturers have begun to use spiral stem removal devices for automatic stem removal, utilizing spiral blades in conjunction with a feed mechanism. There are automated methods for removing the stems from mustard greens. For example, Chinese utility model application CN210299401U discloses a spiral stem-removing device for pickling mustard greens, including a mounting frame, spiral blades, an ultrasonic detection mechanism, a stem-removing and cutting mechanism, and a microcontroller. The mounting frame includes a first vertical mounting plate, and the spiral blades are installed in a through hole in the middle of the first vertical mounting plate. The ultrasonic detection mechanism includes a signal processor and an ultrasonic ranging sensor. However, this type of spiral stem-removing equipment has the following drawbacks:

[0003] The irregular shape of the mustard greens means that the depth of cut is affected by the position of the spiral blade. Therefore, a servo motor is used to adjust the blade position. However, the inner diameter of the blade is inconvenient, and during adjustment, the cutting depth may be standard on one side while the cutting depth is too deep on the other, affecting the stem removal effect. In addition, the mustard greens are fixed with nails, which are narrow and prone to shifting due to the cutting force of the spiral blade, causing jamming. Moreover, after cutting with the spiral blade alone, the cut outer skin may stick to the surface of the mustard greens, which sometimes needs to be peeled off manually, resulting in low automation.

[0004] To address these issues, we propose an automated spiral stem-removing device for pickling pickled mustard tubers. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The position adjustment structure uses dual servo lead screws to achieve overall horizontal and vertical coarse and fine adjustments of the processing mechanism. Then, in conjunction with the diameter-changing effect of the segmented spiral blade structure, it can adjust the cutting position according to the feeding state of the vegetable head. It not only adjusts the position but also changes the diameter to ensure accurate cutting. The matching micro-floating component forms a two-way elastic buffer compensation. When the outer diameter of the vegetable head changes suddenly or the local bulge squeezes the blade, the micro-floating component passively and elastically yields and unloads the force to ensure the stem-removing effect.

[0020] 2. The segmented spiral cutter structure adopts an inner variable diameter cutter for conformal cutting, plus an outer guide structure with elastic rollers for encircling and limiting the closed loop constraint structure. The extrusion roller of the guide structure relies on the second torsion spring to form radial floating compensation, and flexibly lifts and limits the workpiece from multiple points on the outer periphery to offset the lateral thrust generated by the spiral cutter cutting. It constrains the vegetable head to keep it coaxial and centered throughout the entire process. In addition, it is combined with micro-floating components to form position compensation, so as to avoid jamming and material jamming.

[0021] 3. The segmented spiral blade unit uses rotational cutting to roughly peel the surface of the cabbage head and break open the exposed hard ribs. The torsion spring-type rib-removing knife removes the adhesion. The two work together to form a process linkage of first rotary cutting to open the groove and then elastically tearing away the remaining ribs, eliminating the need for manual secondary trimming of the remaining skin.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1:

[0048] Please see Figure 1-10 The present invention provides a technical solution: an automated spiral stem-removing device for pickling mustard tubers, comprising a frame structure 1, the frame structure 1 including a base frame 11, a vertical frame plate 12 fixedly connected to the top surface of one end of the base frame 11, a processing mechanism 2 provided on the side wall of the vertical frame plate 12, a visual monitor 5 provided on the side wall of the base frame 11 above the processing mechanism 2, a position adjustment structure 3 also provided on the side wall of the vertical frame plate 12, the position adjustment structure 3 being connected to the processing mechanism 2, and a feeding structure 4 provided on the top surface of the base frame 11;

[0049] The processing mechanism 2 includes a segmented spiral blade structure 21, a stripping structure 22, and a guide structure 23. The segmented spiral blade structure 21 is located between the stripping structure 22 and the guide structure 23. The stripping structure 22 is located near the support plate 12, and the guide structure 23 is located away from the support plate 12. The segmented spiral blade structure 21 includes a first annular frame 211, with multiple blade holders 214 evenly arranged on its inner side. Each blade holder 214 has a spiral blade unit 213 fixedly connected to its inner side. The stripping structure 22 includes a second annular frame 221, with multiple supports 224 evenly arranged on its inner side. A hinge 2217 is fixedly connected to each support 224, and the hinge 2217 rotatably connects to the end of the stripping blade 223. The guide structure 23 includes a third annular frame 231, with multiple supports 224 evenly arranged on its inner side. The hinge 234 is rotatably connected to one end of the swing arm 2317, and the other end of the swing arm 2317 is rotatably connected to the extrusion wheel 233. Multiple spiral blade units 213 form a spiral-shaped blade body. Through the multiple spiral blade units 213, the diameter can be changed. When processing the cabbage head, not only can the position of the spiral blade body be slightly adjusted by the position adjustment structure 3, but the positions of multiple spiral blade units 213 can also be adjusted synchronously to adapt to the shape of the cabbage head feeding position, ensuring a suitable cutting depth and reducing the risk of the cabbage head getting stuck. The guide structure 23 is used to provide auxiliary flexible positioning for the outer side of the cabbage head. In this way, when processing the stem, the position of the outer side of the cabbage head is limited, and it no longer relies solely on the flower nail 45 for fixation, avoiding the cabbage head from being tilted by force and avoiding getting stuck. The tendon-removing structure 22 is used to further remove the tendons from the cabbage head after the stem is removed, and to completely remove the sticky hard skin.

[0050] The position adjustment structure 3 includes a side frame 31, the top side wall of a vertical plate 32 is horizontally slidably mounted on the side wall of the side frame 31, and a sliding rod 33 is slidably mounted on the bottom end of the vertical plate 32. A micro-floating component 34 is provided at the bottom end of the sliding rod 33. The micro-floating component 34 is connected to the processing mechanism 2. The position adjustment structure 3 is used to make micro-adjustments to the position of the processing mechanism 2 to adapt to the feeding state of the mustard greens. The micro-floating component 34 can float slightly in two directions. The floating position is within the allowable range of cutting depth error. This dual-axis floating can ensure that the mustard greens pass smoothly through the position of the processing mechanism 2 and avoid hard jamming.
