Description

Technical Field

[0001] This invention relates to the field of sweet potato starch processing technology, specifically to a sweet potato starch production cutting and separating mechanism. Background Technology

[0002] The sweet potato starch processing process involves several steps, including mixing the slurry, feeding the raw materials, spreading the slurry, steaming and shaping, rolling, aging, vertical cutting, shaping and drying (to 90% dry), horizontal cutting to a fixed length, bundling or not bundling, and secondary drying. The vertical cutting step generally uses two opposing rotating rollers to cut the large sweet potato skin into wide noodles.

[0003] However, during the vertical cutting process, the sweet potato starch is at the critical point between aging and non-aging. The sweet potato starch has a large amount of moisture and viscosity, so the wide noodles after vertical cutting are very easy to stick together, which affects the yield of the product. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a sweet potato starch production cutting and separating mechanism to separate vertically cut wide noodles, prevent the wide noodles from sticking together, and improve the product yield.

[0005] The present invention provides a sweet potato starch production cutting and separating mechanism, including a frame and a vertical cutting mechanism installed on the upper part of the frame. The vertical cutting mechanism includes two rollers rotatably mounted on the frame and capable of rotating in opposite directions under the drive of a power mechanism. The vertical cutting mechanism can cut large sweet potato skins passing between the two rollers into several wide noodles.

[0006] It also includes a separation mechanism installed at the lower part of the frame. The separation mechanism includes a guide shaft and a plurality of separation plates spaced apart along the length of the guide shaft. The guide shaft is parallel to the two roller cutters. The two ends of the guide shaft are respectively mounted on the frame through mounting seats. The wide powder formed by the two roller cutters is discharged from the lower part of the guide shaft, and each of the separation plates is inserted one-to-one between the adjacent wide powders.

[0007] Furthermore, the frame is provided with supports on both sides, and a connecting part is provided at the top of the support near the side end. The bottom of the mounting seats at both ends of the guide shaft is respectively supported on the upper side of the side end of the corresponding side support. The side of the mounting seat that extends beyond the side end of the support is inclined downwards, and the side of the mounting seat that is above the support is inclined upwards and connected to the connecting part by hook.

[0008] Furthermore, the connecting part is a screw, and the side of the mounting base is provided with a connecting lug. The connecting lug has a strip-shaped hole. The side of the mounting base located above the bracket is fitted onto the screw through the strip-shaped hole on the connecting lug. A nut located on the upper side of the connecting lug is fitted onto the screw.

[0009] Furthermore, the guide shaft is provided with a plurality of first threaded connection holes spaced apart along its length direction, and one end of the separating plate is provided with a first threaded connector, each of the first threaded connectors being threadedly connected to each of the first threaded connection holes.

[0010] Furthermore, the guide shaft includes a hollow tube with a groove along its length on the tube wall. Several sliders are fitted inside the hollow tube, and the sliders are connected by the same spring. Each separating piece is fixedly connected to the slider and passes through the groove. A drive rod is rotatably mounted between the two mounting seats, passing through each slider and the spring in sequence. The drive rod has two threads with opposite directions. The sliders at both ends have threaded holes that mate with the two threads on the drive rod. Each slider except at both ends has a clearance hole for the drive rod to pass through.

[0011] Furthermore, each slider is provided with a second threaded connection hole at the position corresponding to the slide groove, and one end of the separating piece is provided with a second threaded connector, and each second threaded connector is threadedly connected to each of the second threaded connection holes.

[0012] Furthermore, the inner wall of the hollow tube is provided with a guide rail extending along the length direction, and each slider is provided with a guide groove adapted to the guide rail.

[0013] Furthermore, each of the two mounting bases has a plug-in hole on its inner side, and the two ends of the hollow tube are respectively inserted into the plug-in holes on the two mounting bases.

[0014] Furthermore, the drive rod is mounted on two mounting seats via bearings, and both ends of the drive rod extend out of the two mounting seats and are provided with drive parts.

[0015] Furthermore, the top of the frame is provided with a top cover, and a feed inlet is provided on the top cover between the two roller cutters. A feed guide roller is provided on the top of the top cover above the feed inlet.

[0016] The beneficial effects of this invention are as follows: after the sweet potato skin is cut into wide noodles by two opposing rotating rollers, it is discharged through the guide shaft below. When the wide noodles pass through the guide shaft, the separating plates on the guide shaft can separate the wide noodles that stick together after cutting. After the wide noodles are separated, they can enter the next drying or cross-cutting process. This can prevent the wide noodles from sticking together after vertical cutting and improve the product yield. Attached Figure Description

Detailed Implementation

[0025] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0026] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by those skilled in the art.

[0027] Example 1

[0028] One embodiment of the present invention provides a sweet potato starch production cutting and separating mechanism, such as... Figure 1 and Figure 2 As shown, it includes a frame 100, a vertical cutting mechanism 200 mounted on the upper part of the frame 100, and a separation mechanism 300 mounted on the lower part of the frame 100.

[0029] The vertical cutting mechanism 200 includes two roller cutters 210 rotatably mounted on the frame 100 and capable of rotating in opposite directions under the drive of a power mechanism. The vertical cutting mechanism 200 is capable of cutting large sweet potato skins passing between the two roller cutters 210 into several wide noodles.

[0030] Preferably, the top of the frame 100 is provided with a top cover 120, and a feed inlet 121 is provided on the top cover 120 aligned between the two roller cutters 210. A feed guide roller 130 is provided on the top of the top cover 120 above the feed inlet 121, and the large sweet potato skin can be guided into the space between the two roller cutters 210 for cutting through the feed guide roller 130.

[0031] The separation mechanism 300 includes a guide shaft 310 and a plurality of separation plates 320 spaced apart along the length of the guide shaft 310. The guide shaft 310 is parallel to two roller cutters 210. The two ends of the guide shaft 310 are respectively mounted on the frame 100 through mounting bases 330. Wide powder formed by the two roller cutters 210 is discharged from the lower part of the guide shaft 310, and each separation plate 320 is inserted one-to-one between adjacent wide powders.

[0032] Using the above scheme, sweet potato peel is cut into wide noodles by two opposing rotating rollers 210 and then discharged through the guide shaft 310 below. When the wide noodles pass through the guide shaft 310, the separating plates 320 on the guide shaft 310 can separate the wide noodles that stick together after cutting. After the wide noodles are separated, they can enter the next drying or cross-cutting process. This can prevent the wide noodles from sticking together after vertical cutting and improve the product yield.

[0033] It should be noted that the guide shaft 310 in this embodiment is fixed and does not rotate. When the guide shaft 310 guides the cut wide powder, the guide shaft 310 slides relative to the wide powder. In order to reduce the friction between the guide shaft 310 and the wide powder, the surface of the guide shaft 310 in contact with the wide powder needs to be smooth and lubricated.

[0034] In this embodiment, the frame 100 has supports 110 on both sides, and a connecting part is provided at the top of the support 110 near the side. The bottom of the mounting seats 330 at both ends of the guide shaft 310 is supported on the upper side of the corresponding side end of the support 110. The side of the mounting seat 330 extending beyond the side end of the support 110 is inclined downwards, and the side of the mounting seat 330 above the support 110 is inclined upwards and connected to the connecting part by a hook. Specifically, the connecting part is a screw 111, and the side of the mounting seat 330 is provided with a connecting ear 331. The connecting ear 331 has a strip hole 332. The side of the mounting seat 330 above the support 110 is fitted onto the screw 111 through the strip hole 332 on the connecting ear 331. A nut 112 located on the upper side of the connecting ear 331 is fitted onto the screw 111. With the above design, during the conveying process, the guide shaft 310 can swing up and down under the pull of the wide powder, which can effectively prevent the wide powder from being pulled apart.

[0035] In this embodiment, refer to Figure 2 The guide shaft 310 has a number of first threaded connection holes 311 spaced apart along its length. One end of the separating plate 320 is provided with a first threaded connector 321. Each first threaded connector 321 is threadedly connected to each first threaded connection hole 311. This facilitates the installation and disassembly of the separating plate 320, and makes it easier to replace the damaged separating plate 320.

[0036] Example 2

[0037] Another embodiment of the present invention provides a sweet potato starch production cutting and separation mechanism. The specific structure of the guide shaft 310 in this embodiment is different from that in embodiment 1.

[0038] Specific reference Figures 3-6 As shown, the guide shaft 310 includes a hollow tube 312. A groove 313 is provided on the wall of the hollow tube 312 along the length direction. Several sliders 340 are adapted inside the hollow tube 312. The same spring 350 is connected between each slider 340. Each separating piece 320 is fixedly connected to each slider 340 and passes through the groove 313. A drive rod 360 is rotatably installed between two mounting seats 330, passing through each slider 340 and the spring 350 in sequence. The drive rod 360 is provided with two sections of threads with opposite directions. The sliders 340 near both ends are provided with screw holes 341 that respectively mate with the two sections of threads on the drive rod 360. Each slider 340 except for the two ends is provided with a clearance hole 342 for the drive rod 360 to pass through.

[0039] This application ensures that the distance between each slider 340 remains the same by setting sliders 340 inside the hollow tube 312 and connecting identical springs 350 (i.e., the springs 350 have the same length and elastic coefficient) between sliders 340. This ensures that the distance between each separating plate 320 remains the same. When the sliders 340 at both ends are driven to move towards each other in the middle by the drive rod 360, the distance between each separating plate 320 can be reduced simultaneously. When the sliders 340 at both ends are driven to move away from each other in the opposite direction by the drive rod 360, the distance between each separating plate 320 can be increased simultaneously. Therefore, this application can adjust the distance between each separating plate 320 by the drive rod 360 to adapt to the separation of wide powders of different widths.

[0040] Preferably, each slider 340 has a second threaded connection hole 344 at a position corresponding to the slide groove 313, and one end of the separating plate 320 has a second threaded connector 322. Each second threaded connector 322 is threadedly connected to each second threaded connection hole 344. This structure facilitates the installation and removal of the separating plates 320, making it easier to replace damaged plates. Furthermore, while the drive rod 360 can only adjust the distance between the separating plates 320 within a small range, this application allows setting the distance between the separating plates 320 on each slider 340 to the minimum unit width. When a large range of width adjustment is required, separating plates 320 can be installed on sliders 340 at equal intervals, making the distance between the separating plates 320 close to the width of the wide powder. Then, the drive rod 360 can be used to fine-tune the distance between the separating plates 320 until it equals the width of the wide powder, thus expanding the applicable width range for wide powder.

[0041] To improve the stability of the sliding of the slider 340, a guide rail 314 extending along the length direction is provided on the inner wall of the hollow tube 312, and each slider 340 is provided with a guide groove 343 that is adapted to the guide rail 314.

[0042] To facilitate the fixed connection between the two ends of the hollow tube 312 and the mounting base 330, each of the two mounting bases 330 has a plug hole 333 on its inner side, and the two ends of the hollow tube 312 are respectively inserted into the plug hole 333 on the two mounting bases 330.

[0043] In addition, the drive rod 360 is mounted on the two mounting seats 330 via bearings 334. The two ends of the drive rod 360 extend out of the two mounting seats 330 respectively and are provided with drive parts 361. This makes it easy to adjust the spacing between the separation plates 320 by rotating the drive rod 360 through the drive parts 361.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
