Description

Technical Field

[0001] This invention specifically relates to a device and method for preserving the fibrous structure of a continuous de-coring and shaping process for loofah, belonging to the field of agricultural product processing machinery. Background Technology

[0002] Loofah sponge is a natural fibrous structure formed after the loofah has matured and dried. A complete loofah sponge structure mainly consists of three parts: an outer phloem, a middle reticular fiber skeleton, and an inner core tissue that encloses the seeds. In recent years, with the continuous expansion of loofah sponge applications in fields such as biomedicine, beauty and personal care, household cleaning, and environmentally friendly composite materials, the market demand for high-quality, standardized loofah sponge products has exploded. Among these processes, the separation of the sponge from the core, commonly known as core removal, is the core process that determines the quality and economic value of the finished loofah sponge.

[0003] Currently, over 90% of loofah sponge processing still relies on manual de-coring. Each loofah sponge requires multiple manual processes, including pounding, crushing, hollowing, and cleaning. This process is not only time-consuming and extremely inefficient, but also results in over 60% of the finished product exhibiting problems such as fiber breakage, sponge residue, and uneven appearance, directly leading to a decline in product grade. A few large-scale enterprises use customized large-scale de-coring equipment, but these generally suffer from the following drawbacks: First, it has poor adaptability to natural differences in diameter, length, dryness and humidity of loofah sponge. During the core removal process, it is very easy to damage the natural fiber structure of loofah sponge, destroy the integrity of the finished product, resulting in a large waste and affecting the strength of subsequent use. Secondly, existing equipment mainly relies on single crushing or hollow drill bit excavation as its main principle. The fixing method is not standardized and there is a lack of standardized excavation methods. It cannot take into account both the thoroughness of core removal and fiber integrity, and it is difficult to achieve continuous processing of multi-specification raw materials. Third, the lack of a structure to limit the position of the loofah sponge during the core removal process causes the loofah sponge to rotate, affecting the core removal effect.

[0004] As the shortage of skilled workers in loofah sponge processing continues to widen and labor costs rise year by year, the contradiction between market demand for high-quality, standardized loofah sponge products and low efficiency in the processing process is becoming increasingly prominent.

[0005] In summary, given the natural shape and internal structure of loofah, there is no standardized continuous processing method for removing the core and hollowing out the loofah. As a result, the processing of the loofah is often affected by misalignment and waste due to the rotation of the loofah fibers and the different sizes of the loofahs. Summary of the Invention

[0015] A method for preserving the core in continuous decoring and forming of loofah sponge is implemented using the aforementioned device. The method involves first installing the loofah on a cutting straightening component, then feeding the loofah into a feeding conveying assembly through the cutting straightening component. The feeding conveying assembly drives the loofah forward at a predetermined speed. When the loofah passes the opening component, the opening component cuts an opening along its axial direction according to predetermined requirements. At the same time, the opening and exposure component simultaneously expands the loofah along a circumferential area of ​​4-6 mm radially from its outer surface. The opening method is to gradually expand outward to expose the inner core. Then, the inner core coarse cutting component coarsely slices the exposed inner core. As the loofah continues to move forward, it is flattened by the flattening component and the fine decoring component scrapes off the remaining inner core. Then, using the hinge of the rotating component and the vertical displacement frame as the axis, rotate the rotating component to ensure that the supporting rod is vertically upward. Pinch the two supporting rods together, thereby driving the inner sliding component to squeeze the spring component inward. Insert a supporting rod into each of the two symmetrical holes inside the loofah. At this time, the spring component in the squeezed state resets and pushes the inner sliding component, thereby driving the supporting rod to open to both sides and abut against the inner wall of the loofah, thus defining the position of the loofah as a whole. Then rotate the rotating component again to ensure that the vertical supporting rod is reset and pushes the horizontal displacement frame forward, ensuring that the loofah enters the feeding and conveying assembly and is cut by the opening assembly. Finally, the lifting threaded rod is screwed on, and the lifting threaded rod is threaded to the threaded hole, which drives the vertical displacement frame to move up or down, thereby adjusting the cutting depth of the loofah by the opening assembly. The calibration piece makes it easy to observe the position of the cutting depth. After the above processing is completed, the processed loofah sponge is formed. The processed loofah sponge is then soaked, rubbed and dried to form the finished loofah sponge.

[0016] The beneficial effects of this invention are as follows: The continuous decoring and shaping device for loofah sponge in this invention preserves the ribs by feeding the loofah sponge at a uniform speed through a feeding and conveying component. It sequentially completes the processes of opening, spreading and exposing, coarse cutting of the inner core, flattening and fine planing of the core, realizing a continuous and automated decoring process for loofah. The continuous processing method achieved in the standardized cutting process without manual operation can ensure the integrity of the hard ribs inside the loofah, and is adapted to the natural shape and internal structure of the loofah itself.

[0017] The rib preservation device for continuous core removal and forming of loofah sponge in this invention can accurately control the position through the cut correction component, realizing the standardized cutting process along the natural cavity in the middle of the loofah. This prevents the subsequent expansion and exposure components from being misaligned due to the solid plane of the cut surface, improving the standardization of the expansion and exposure area and the continuity of subsequent standardized operations. This invention uses the expansion rod with the inner sliding component and spring component to achieve pinching and storage of force and automatic reset and tightening. The clamping operation is convenient and can adapt to the inner wall shape of the loofah to achieve a quick and corresponding fixing effect against the inner wall of the loofah.

[0018] The method for preserving the fibrous texture of continuous de-coring and forming of loofah sponge in this invention is a standardized and uniform treatment method that can only be achieved by this device. It can adapt to the shape and internal structure of the loofah for targeted, one-by-one, and continuous standardized treatment, maximizing the preservation of the parts where the loofah sponge is formed, and forming a standardized process for precise cutting and de-coring.

Detailed Implementation

[0021] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0022] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18This embodiment describes a continuous de-coring device for forming loofah sponges, specifically designed for the external shape and internal structure of loofahs. It includes a frame 1, a feeding and conveying assembly 2, an opening assembly 3, a spreading and exposing assembly 4, an inner core coarse cutting assembly 5, a leveling assembly 6, a fine de-coring component 7, and a cut straightening component 8. The frame 1 is equipped with the opening assembly 3, the fine de-coring component 7, the leveling assembly 6, the inner core coarse cutting assembly 5, the spreading and exposing assembly 4, the feeding and conveying assembly 2, and the cut straightening component 8.

[0023] The loofah is installed on the cut straightening component 8 and fed into the feeding conveying component 2 through the cut straightening component 8. The feeding conveying component 2 is used to convey the loofah forward at a uniform speed. After the loofah passes through the opening component 3, the loofah is cut open axially and then gradually opened outward by the expansion and exposure component 4 to expose the inner core. Then the inner core coarse cutting component 5 performs a slicing coarse cut on the exposed inner core. As the loofah continues to move forward, it is flattened by the flattening component 6 and the core removal component 7 scrapes off the remaining inner core. This forms a three-stage sequential core removal path of first removing a large amount of excess, then flattening and shaping, and finally fine scraping.

[0024] The cut straightening component 8 includes a triangular bracket 81, a horizontal displacement bracket 82, a vertical displacement bracket 83, a lifting threaded rod 84, a calibrating component 85, a rotating component 86, an inner sliding component 87, a spring component 88, and a spreading rod 89. The inner wall of the triangular bracket 81 is machined with a groove 81-1. The outer wall of the horizontal displacement bracket 82 is provided with a strip 821, which passes through the groove 81-1. The inner wall of the horizontal displacement bracket 82 is machined with a second groove 82-2. A threaded hole 82-1 is machined on the horizontal displacement bracket 82, and a lifting threaded rod 84 passes through the threaded hole 82-1. The lifting threaded rod 84 and... The threaded hole 82-1 is threaded, and the end of the lifting threaded rod 84 is hinged to the bottom of the vertical displacement frame 83. The outer wall of the vertical displacement frame 83 is provided with a strip-shaped part 831, which passes through the slide groove 82-2. The vertical displacement frame 83 is provided with a calibration part 85. The vertical displacement frame 83 is hinged with a rotating part 86. The rotating part 86 is machined with an inner slide groove 86-1 along its length. An inner slide part 87 passes through the inner slide groove 86-1. The inner slide part 87 is provided at the end of the spring part 88. The spring part 88 is placed in the inner slide groove 86-1. A support rod 89 is provided on the inner slide part 87.

[0025] With the hinge of the rotating part 86 and the vertical displacement frame 83 as the axis, rotate the rotating part 86 so that the supporting rod 89 is vertically upward, pinch the two supporting rods 89 together, so that the inner sliding part 87 pushes the spring part 88 inward. At this time, insert the symmetrical holes of the loofah into the two supporting rods 89 respectively. The compressed spring part 88 returns to its original position and pushes the inner sliding part 87 to push the supporting rod 89 to both sides, and it is pressed against the inner wall of the loofah, thereby limiting the position of the loofah. Then rotate the rotating part 86 so that the vertical supporting rod 89 returns to its original position and pushes the horizontal displacement frame 82 forward, so that the loofah enters the feeding and conveying assembly 2 and is cut by the opening assembly 3.

[0026] Tighten the lifting threaded rod 84, which is threadedly connected to the threaded hole 82-1, causing the vertical displacement frame 83 to rise or fall, thereby adjusting the cutting depth of the loofah by the opening assembly 3. The calibration piece 85 facilitates observation of the cutting depth position.

[0027] Most loofahs have four holes. The spreading rod 89 limits the cutting position when the loofah is cut by the opening component 3, so that the opening component 3 can cut along the hollow cavity in the middle of the loofah. The cut will directly break through the internal cavity. The cut surface has a hollow notch. The edge of the hollow notch is convenient for the spreading and exposing component 4 to spread open, avoiding cutting the solid fiber hard ribs of the loofah. Once the cut surface forms a complete and continuous solid plane, the spreading and exposing component 4 will push the cut loofah high, causing misalignment, which is not convenient for subsequent operations.

[0028] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. The calibration component 85 includes a Z-shaped rod 851, an internally threaded rod 852, a screwing component 853, a base 854, a card holder 855, a rubber gasket 856, and an infrared emitter 857. The Z-shaped rod 851 is mounted on the vertical displacement frame 83. A sliding groove 851-1 is machined on the Z-shaped rod 851. The internally threaded rod 852 is hinged within the sliding groove 851-1. The end of the internally threaded rod 852 is provided with a screw... The screw 853 and the base 854 are inserted into the slide groove 851-1. The base 854 has an internally threaded rod 852 inserted along its thickness direction. The internally threaded rod 852 is threadedly connected to the base 854. The base 854 has a circular groove 854-1. A rubber gasket 856 is placed in the circular groove 854-1. A retainer 855 is hinged in the circular groove 854-1. The bottom of the retainer 855 is attached to the rubber gasket 856. An infrared emitter 857 is installed on the retainer 855.

[0029] Open the infrared emitter 857 and align it with the opening assembly 3 to facilitate intuitive reading of the cutting depth. Rotate the internal thread rod 852 by screwing the screw 853. The internal thread rod 852 is threadedly connected to the base 854, causing the base 854 to move the infrared emitter 857 along the slide groove 3 851-1, thereby adjusting the position of the infrared emitter 857. The holder 855 can rotate, thereby adjusting the irradiation angle of the infrared emitter 857. The rubber gasket 856 and the holder 855 form a squeezing friction force, so that the holder 855 can rotate and remain stable without shifting after rotation.

[0030] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. The leveling component 6 includes a metal roller 61, an L-shaped plate 62, a screw 63, and an L-shaped seat 64. The end of the metal roller 61 is hinged to the L-shaped plate 62. The screw 63 is threaded through the L-shaped plate 62 and is threadedly connected to the L-shaped plate 62. The end of the screw 63 is hinged to the L-shaped seat 64, and the L-shaped seat 64 is mounted on the frame 1.

[0031] After being conveyed by the feeding conveyor assembly 2, the loofah enters the metal roller 61 and is squeezed by the metal roller 61. After being output from between the metal roller 61 and the frame 1, the loofah is flattened. The height of the L-shaped plate 62 can be adjusted by rotating the screw 63, thereby adjusting the distance between the metal roller 61 and the frame 1.

[0032] Specific Implementation Method 4: This implementation method is a further limitation of Specific Implementation Methods 1, 2 or 3. The inner core rough cutting assembly 5 includes a rotating blade assembly 51, a rotating shaft 52, a transmission belt 53, a pulley 54 and a fixing member 55. The rotating blade assembly 51 is provided at one end of the rotating shaft 52, and the pulley 54 is provided at the other end of the rotating shaft 52. The fixing member 55 is mounted on the rotating shaft 52 and is provided on the frame 1. The transmission belt 53 is wound around the outer circumference of the pulley 54 and is wound around the core removal part 7. The frame 1 has blade edges 1-2 machined on it, and the rotating blade assembly 51 passes through the blade edges 1-2.

[0033] The rotating blade assembly 51 consists of 4 to 5 parallel disc-shaped blades with a spacing of 2 to 5 mm between adjacent blades. After being cut by the opening component 3, the loofah is opened by the exposure component 4 and passes through the rotating blade assembly 51. The rotating blade assembly 51 coarsely cuts the loofah core.

[0034] Specific Implementation Method 5: This implementation method further defines Specific Implementation Methods 1, 2, 3, or 4. The fine planing core removal component 7 includes a limiting component 71, an arc-shaped fitting planing blade and cutter roller 72, a second pulley 73, a second transmission belt 74, a drive pulley 75, and a first motor 76.

The first transmission belt 53 is wound around the drive pulley 75, and the second transmission belt 74 is wound around both the drive pulley 75 and the second pulley 73. The second pulley 73 is located at the end of the arc-shaped fitting planing blade and cutter roller 72. The end of the arc-shaped fitting planing blade and cutter roller 72 is hinged within the limiting component 71. The limiting component 71 is mounted on the frame 1, and a planing blade opening 1-1 is machined on the frame 1. The arc-shaped fitting planing blade and cutter roller 72 passes through the planing blade opening 1-1.

[0035] In this embodiment, the first motor 76 drives the active pulley 75 to rotate. The active pulley 75 drives the second pulley 73 and the first pulley 54 to rotate through the second transmission belt 74 and the first transmission belt 53, respectively. The second pulley 73 drives the arc-shaped fitting planer and the cutter roller 72 to rotate. The arc-shaped fitting planer and the cutter roller 72 perform fine core-shaping operations on the loofah that has passed through the leveling component 6.

[0036] In this embodiment, pulley 54 drives the rotating blade assembly 51 to rotate via rotating shaft 52 to perform coarse cutting on the loofah that has passed through the exposed component 4.

[0037] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Method One, Two, Three, Four or Five. The exposed component 4 includes an inverted triangular bracket 41, a narrow component 42 and a wide component 43. The inverted triangular bracket 41 is disposed on the frame 1. The narrow component 42 is disposed on the frame 1. The narrow component 42 is disposed at the end of the inverted triangular bracket 41 and the wide component 43 is disposed at the end of the narrow component 42.

[0038] In this embodiment, the loofah cut by the opening component 3 is initially stretched open by the end of the inverted triangular support 41, and is gradually stretched larger by the narrow component 42 and the wide component 43.

[0039] Specific implementation method seven: This implementation method is a further limitation of specific implementation methods one, two, three, four, five or six. The opening component 3 includes a cutting blade 31 and a second motor 32. The output end of the second motor 32 is provided with the cutting blade 31. The frame 1 is processed with cutting holes 1-3. The cutting blade 31 passes through the cutting holes 1-3. The second motor 32 is provided on the frame 1.

[0040] In this embodiment, the second motor 32 drives the cutting blade 31 to rotate, performing an opening operation on the loofah under controlled positioning within a standardized area.

[0041] Specific Implementation Method Eight: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, Five, Six, or Seven. The feeding and conveying assembly 2 includes a motor 21, a drive sprocket 22, multiple vertical plates 23, multiple conveying rollers 24, multiple driven sprockets 25, a first chain 26, and multiple second chains 27. The motor 21 is mounted on the frame 1. The output end of the motor 21 is provided with the drive sprocket 22. The end of each conveying roller 24 is respectively hinged to the vertical plate 23 corresponding to its position. The vertical plate 23 is mounted on the frame 1. Each end of the conveying roller 24 that passes through the vertical plate 23 is respectively provided with a driven sprocket 25. The first chain 26 is wound around both the drive sprocket 22 and the driven sprocket 25. A second chain 27 is wound around every two adjacent driven sprockets 25.

[0042] In this embodiment, motor 21 drives the drive sprocket 22 to rotate. The drive sprocket 22 drives a driven sprocket 25 to rotate via the first chain 26. The driven sprocket 25 drives all the driven sprockets 25 to rotate via the second chain 27, thereby causing all the conveying rollers 24 to rotate, so as to achieve the purpose of the conveying rollers 24 rotating to drive the loofah forward.

[0043] In practical use, this invention employs a fixed, non-powered inverted triangular support as the exposure unit, utilizing the conveying motion of the loofah itself to achieve adaptive exposure. It is compatible with loofah raw materials of different diameters and wall thicknesses, eliminating the need for pre-sorting and grading, thus exhibiting strong versatility and fundamentally avoiding damage to the fibers caused by the active clamping mechanism.

[0044] The processing method of this invention adopts a two-stage core removal process of rough cutting followed by fine planing, supplemented by a leveling component to flatten the surface to be processed, forming a three-stage sequential core removal path: first, large excess material is removed; then, it is flattened and shaped; and finally, it is finely scraped according to the shape. First, more than 80% of the inner core is quickly removed by multiple blades, and then the remaining inner core is scraped off by an arc-shaped planer blade. This ensures a core removal rate of more than 95% while maximizing the protection of the integrity of the outer fiber skeleton and reducing the breakage rate of the finished product.

[0045] The overall structure of this invention has no complex circuits or control logic, and the driving source only requires a 220V single-phase power supply. The equipment is plug-and-play upon placement. It has a compact structure, low manufacturing cost, and simple daily maintenance, and can be flexibly adapted to various application scenarios such as individual processing, cooperative mass production, and large-scale factory production.

[0046] Specific Implementation Method Nine: Combining Figures 1 to 14This embodiment describes a standardized core removal method implemented solely by this device. The method is preferably performed on semi-aged, firm loofahs. Specifically, the loofah is first mounted on a cutting correction component 8 and fed into a feeding conveyor assembly 2 via the cutting correction component 8. The feeding conveyor assembly 2 conveys the loofah forward at a uniform speed. After passing through an opening component 3, the loofah is axially cut open. Simultaneously, an exposing component 4 expands the loofah along a circumferential area 4-6 mm radially from its outer surface to expose the inner core. Then, an inner core coarse cutting component 5 coarsely slices the exposed inner core. As the loofah continues forward, it is flattened by a flattening component 6 while a fine core removal component 7 scrapes away any remaining inner core.

[0047] With the hinge of the rotating part 86 and the vertical displacement frame 83 as the axis, rotate the rotating part 86 so that the supporting rod 89 is vertically upward, pinch the two supporting rods 89 together, so that the inner sliding part 87 pushes the spring part 88 inward. At this time, insert the symmetrical holes of the loofah into the two supporting rods 89 respectively. The compressed spring part 88 returns to its original position and pushes the inner sliding part 87 to push the supporting rod 89 to both sides, and it is pressed against the inner wall of the loofah, thereby limiting the position of the loofah. Then rotate the rotating part 86 so that the vertical supporting rod 89 returns to its original position and pushes the horizontal displacement frame 82 forward to ensure that the loofah enters the feeding and conveying assembly 2 and is cut by the opening assembly 3.

[0048] Tighten the lifting threaded rod 84, which is threadedly connected to the threaded hole 82-1, causing the vertical displacement frame 83 to rise or fall, thereby adjusting the cutting depth of the loofah by the opening assembly 3. The calibration piece 85 facilitates observation of the cutting depth position.

[0049] Most loofahs have four holes. The spreading rod 89 defines the cutting position when the loofah is cut by the opening component 3, allowing the opening component 3 to cut along the hollow cavity in the middle of the loofah. The cut will directly break through the internal cavity, and the cut surface has a hollow notch. The edge of the hollow notch facilitates the spreading operation area of ​​the spreading and exposing component 4, ensuring the integrity of the solid fibrous ribs of the loofah. This ensures that the cutting area is outside the fibrous ribs. If the cut surface forms a complete and continuous solid plane, the spreading and exposing component 4 will lift the cut loofah, causing misalignment, which will be inconvenient for subsequent operations. The above operation can ensure that the present invention can perform continuous and effective standardized cutting of the loofah, preserving the effective area of ​​the loofah with fibrous ribs and other parts.

[0050] This invention achieves a three-stage sequential core removal process for loofah by coordinating the feeding and conveying component 2, the opening component 3, the spreading and exposing component 4, the inner core coarse cutting component 5, the flattening component 6, the fine planing and core removal component 7, and the cut straightening component 8. This process involves first removing a large amount of core from the loofah, then flattening and shaping it, and finally finely scraping it to conform to its shape. This ensures thorough core removal while maximizing the protection of the integrity of the outer fiber skeleton.

9. A method for preserving the ribs in continuous de-coring and forming of loofah sponges, implemented using the rib-preserving treatment device for continuous de-coring and forming of loofah sponges as described in any one of claims 1 to 8, characterized in that: The method of preserving the core is as follows: First, the loofah is installed on the cutting correction component (8). The loofah is fed into the feeding conveying component (2) through the cutting correction component (8). The feeding conveying component (2) drives the loofah forward at a predetermined speed. When the loofah passes the opening component (3), the opening component (3) cuts an opening along its axial direction according to the predetermined requirements. At the same time, the opening and exposure component (4) is used to open the loofah along the outer surface of the loofah to the radial 4-6 mm circumferential area as a reference. The opening method is to gradually open it outward to expose the inner core. Then the inner core coarse cutting component (5) coarsely cuts the exposed inner core. The loofah continues to move forward and is flattened by the flattening component (6) while the core removal component (7) scrapes off the residual inner core. Then, using the hinge of the rotating part (86) and the vertical displacement frame (83) as the axis, rotate the rotating part (86) to ensure that the supporting rod (89) is vertically upward, pinch the two supporting rods (89) together, thereby driving the inner sliding part (87) to squeeze the spring part (88) inward, inserting a supporting rod (89) into each of the two symmetrical holes inside the loofah. At this time, the spring part (88) in the squeezed state resets and pushes the inner sliding part (87), thereby driving the supporting rod (89) to spread to both sides and stick to the inner wall of the loofah, thereby limiting the position of the loofah as a whole. Then rotate the rotating part (86) again to ensure that the vertical supporting rod (89) is reset, and push the horizontal displacement frame (82) forward to ensure that the loofah enters the feeding conveying assembly (2) and is cut by the opening assembly (3). Finally, the lifting threaded rod (84) is screwed on, and the lifting threaded rod (84) is threaded to the threaded hole (82-1), which drives the vertical displacement frame (83) to move up or down, thereby adjusting the cutting depth of the loofah by the opening assembly (3). The calibration piece (85) is used to observe the position of the cutting depth. After the above processing is completed, the processed loofah sponge is formed. The processed loofah sponge is then soaked, rubbed and dried to form the finished loofah sponge.
