DETAILED DESCRIPTION

[0036] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0037] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0038] See also Figures 1 to 10 The present invention provides a lotus seed peeling device 100, which includes a base body 10, a feeding device 20 and a skin grinding device arranged on the base body 10. The base body 10 is used to carry and fix the lotus seed peeling device 100, and has a first station 11 and a second station 12 arranged in sequence in the conveying direction. The feeding device 20 is used to transport lotus seeds in the conveying direction so that the lotus seeds are transported through the first station 11 and the second station 12 in sequence. The specific structure of the feeding device 20 is not limited, as long as it can realize the transportation of lotus seeds and the cooperation with the skin grinding device. The skin grinding device includes a first skin grinding device 30 arranged at the first station 11 and a second skin grinding device 40 arranged at the second station 12, the first skin grinding device 30 is used to remove the outer skin of the lotus seeds on the short axis circumference, and the second skin grinding device 40 is used to remove the outer skin of the lotus seeds on the long axis end surface.

[0039] In this embodiment, the first dermabrasion device 30 and the second dermabrasion device 40 are separately provided to effectively remove the outer skin of the lotus seeds on the short axis circumference and the long axis end surface, thereby avoiding the problem of incomplete peeling, and the first dermabrasion device 30 and the second dermabrasion device 40 cooperate to accurately control the degree of peeling, thereby avoiding excessive grinding and affecting product quality. In addition, in this embodiment, by respectively providing the first dermabrasion device 30 and the second dermabrasion device 40 at two workstations, a reasonable division of labor can be achieved, so that the peeling task at each workstation is more specialized, and the peeling effect is further improved.

[0040] Further, the first station 11 and the second station 12 are sequentially distributed in the up-down direction, and the feeding device 20 includes a first conveyor belt 21 disposed at the first station 11 and a second conveyor belt 22 disposed at the second station 12. Preferably, the first conveyor belt 21 and the second conveyor belt 22 are driven to move by respective driving mechanisms, respectively. Specifically, the driving mechanism may include a driving motor and a driving wheel, and the first conveyor belt 21 and the second conveyor belt 22 are wound around respective driving wheels to move with the rotation of the driving wheels. Preferably, the driving mechanism also includes a tensioning device disposed in the first conveyor belt 21 and the second conveyor belt 22 to support each conveyor belt. In this embodiment, the first conveyor belt 21 and the second conveyor belt 22 distributed up and down increase the size of the lotus seed peeling equipment 100 in the height direction, reduce the floor space, make the structure more compact, and have lower requirements on the production site.

[0041] Specifically, the first conveyor belt 21 and the second conveyor belt 22 extend longitudinally, and are respectively provided with a plurality of troughs 23 spaced apart in the longitudinal direction, each of the troughs 23 extends transversely, and the height of each of the troughs 23 is set to be smaller than the size of the lotus seeds in the short axis direction. Preferably, the maximum size of each of the troughs 23 in the longitudinal direction is designed to be smaller than the long axis size of the lotus seeds and larger than the short axis size of the lotus seeds, so that after most of the lotus seeds fall into the troughs 23, the long axis direction thereof is consistent with the extension direction of the troughs 23.

[0042] The first microdermabrasion device 30 is located above the first conveyor belt 21 with a gap between it and the first conveyor belt 21 . The second microdermabrasion device 40 is located above the second conveyor belt 22 with a gap between it and the second conveyor belt 22 .

[0043] In this way, the design of the material trough 23 on the first conveyor belt 21 and the second conveyor belt 22 can ensure that the lotus seeds move stably and orderly during transportation. The height of each material trough 23 is set to be smaller than the size of the lotus seeds in the short axis direction, so that the lotus seeds can be stably placed in the material trough 23, and the exposed part is fully in contact with the skin grinding device. Through the speed difference between the skin grinding device and the feeding device 20, the lotus seeds in the gap move longitudinally while rolling and rotating and the epidermis is ground off under the friction of the skin grinding device. The specific structure of the skin grinding device is not limited. In a preferred embodiment, the skin grinding device includes an abrasive belt. Since the abrasive belt has good elastic-plastic characteristics, the use of the abrasive belt makes the lotus seed peeling device compatible with lotus seeds of a wider size range and can also well prevent damage to the lotus seeds.

[0044] For further information, see Figures 4 to 8 , the cross-section of each of the troughs 23 is gradually reduced in size from top to bottom in the longitudinal direction, so that the lotus seeds can automatically fall into the trough 23, and can roll smoothly without getting stuck. A channel 24 is provided at the bottom of each of the troughs 23, and the powder generated by grinding can fall from the channel 24. Further, the lotus seed peeling device 100 also includes a collecting device 50, and the collecting device 50 includes a dust box 51, a fan 52 and a suction pipeline 53. The dust box 51 is correspondingly arranged in the first conveyor belt 21 and the second conveyor belt 22, and the upper side is open to connect the channel 24, and the fan 52 is connected to the dust box 51 through the suction pipeline 53. In this way, when the collecting device 50 is working, the fan 52 provides negative pressure, so that the powder falling from the trough 23 into the dust box 51 is sucked and collected by the suction pipeline 53, thereby effectively collecting the debris and dust generated during the peeling process, keeping the working environment clean and tidy, and reducing the impact on the equipment and operators. At the same time, this design can also prevent the secondary contamination of lotus seeds by debris and dust, and improve the cleanliness and quality of the product.

[0045] In a preferred embodiment, a plurality of dust boxes 51 are provided to collect dust from the material troughs 23 in each area respectively. Preferably, each dust box 51 is installed detachably to facilitate disassembly and maintenance. Each dust box 51 is provided with an opening on the lateral side wall, and the suction pipeline 53 is connected to the opening through a joint 54, and the inner diameter of the joint 54 is gradually increased from the suction pipeline 53 to the opening. In this way, the design of the joint 54 is utilized to increase the suction area, improve the suction effect, and ensure the stable connection between the suction pipeline 53 and the dust box 51 at the same time, thereby reducing the risk of blockage of the suction pipeline 53 and further improving the stability and service life of the lotus seed peeling device 100.

[0046] For further information, see Figure 6 and Figure 7 The second dermabrasion device 40 includes a first sanding belt 41 and a second sanding belt 42 arranged in sequence along the transmission direction, the surface of the first sanding belt 41 is provided with a plurality of first arc-shaped protrusions 411 distributed in an array, the surface of the second sanding belt 42 is provided with a plurality of second arc-shaped protrusions 421 distributed in an array, and the bending direction of the first arc-shaped protrusion 411 is opposite to the bending direction of the second arc-shaped protrusion 421.

[0047] In this embodiment, the first sanding belt 41 and the second sanding belt 42 are preferably driven to move by their respective driving components to generate a suitable speed difference with the corresponding first conveyor belt 21 and second conveyor belt 22, so as to achieve the best skin grinding effect. Furthermore, the first arc-shaped protrusion 411 and the second arc-shaped protrusion 421 are respectively in the shape of a crescent, and the bending directions of the two are opposite, so that they move relative to the lotus seeds during the movement of the lotus seeds, and grind the outer skin of the lotus seeds on the two end faces of their long axis respectively. The first sanding belt 41 is installed relative to the second conveyor belt 22, and the second sanding belt 42 is installed relative to the second conveyor belt 22 in an adjustable position, for example, they can be installed in a relatively rotatable manner, so that the installation position of the first sanding belt 41 and the second sanding belt 42 can be adjusted according to the peeling effect on the end faces of the long axis of the lotus seeds to obtain the best peeling effect.

[0048] Preferably, Figure 7 As shown, the angle between the extension direction of the first abrasive belt 41 and the second conveyor belt 22 is a, and the angle between the extension direction of the second abrasive belt 42 and the second conveyor belt 22 is -a. In this way, the two end faces of the long axis of the lotus seeds can be symmetrically ground. The angle a is preferably designed to be 10 to 20 degrees, so that the action angle of the first abrasive belt 41 and the second abrasive belt 42 on the lotus seeds is further optimized, ensuring that the force during the peeling process is evenly distributed, and preventing excessive grinding or incomplete peeling. This angle design helps to improve the accuracy and consistency of peeling and ensure the quality and appearance of the product.

[0049] On the basis of the previous embodiment, the lotus seed peeling device 100 further includes a detection device 60, and the detection device 60 includes a second visual detection mechanism 62 disposed between the first sand belt 41 and the second sand belt 42. In this embodiment, the detection device 60 is used to detect the degree of lotus seed grinding during the grinding process, and then the speeds of the first sand belt 41 and the second sand belt 42 are controlled to achieve the purpose of precise grinding, thereby maximizing the grinding efficiency and ensuring product quality. Specifically, the second visual detection mechanism 62 may include a camera and a support, the support is disposed between the first sand belt 41 and the second sand belt 42, and the camera is mounted directly above the second conveyor belt 22, so as to detect the grinding condition of the lotus seeds.

[0050] Further, the first dermabrasion device 30 includes a third sanding belt 31 and a fourth sanding belt 32 sequentially arranged along the transmission direction, and the detection device 60 also includes a first visual detection mechanism 61 arranged between the third sanding belt 31 and the fourth sanding belt 32. It can be understood that the first visual detection mechanism 61 can also include a corresponding camera and a support.

[0051] The third sand belt 31 is used for rough grinding, and the speed of the fourth sand belt 32 is controllable for precise grinding. The lotus seeds transported by the first conveyor belt are firstly rough ground by the third sand belt 31, and then the first visual detection mechanism 61 detects the degree of skin grinding of the lotus seeds. If the skin retention degree after rough grinding by the third sand belt 31 is high, the speed of the fourth sand belt 32 is increased to enhance the grinding effect. On the contrary, if the skin retention degree is low, the speed of the fourth sand belt 32 can be appropriately reduced to reduce the degree of grinding and avoid excessive grinding of lotus seed pulp. In this embodiment, the cooperation of the multi-stage sand belt and the detection device 60 is used to achieve precise control of the lotus seed grinding process and reduce under-grinding and over-grinding.

[0052] Based on the above embodiment, the feeding device 20 also includes a transfer chute 25 arranged between the end of the first conveyor belt 21 and the head end of the second conveyor section. The transfer chute 25 is bent and extended in a direction away from the first conveyor belt 21 and the second conveyor belt 22, and a shielding member is also spaced apart at the end of the transfer chute 25.

[0053] In this embodiment, the transfer slide 25 serves to transfer the ground lotus seeds from the first conveyor belt 21 to the second conveyor belt 22 to continue grinding the long axis end surface. Its curved structure prevents the lotus seeds from getting stuck, ensuring smooth and stable transfer of the lotus seeds. In addition, the transfer slide 25 cooperates with the shielding member to ensure smooth docking of the lotus seeds without falling during the transfer process.

[0054] Based on the above examples, please refer to Fig. 9 and Fig.10The lotus seed peeling equipment 100 also includes a feeding device 70, which is arranged above the head end of the first conveyor belt 21. The feeding device 70 includes a hopper 71, a feeding plate 72, a vibration mechanism 73 and a baffle 74. The feeding plate 72 is arranged to extend downwardly along the longitudinal direction. The hopper 71 is arranged above the feeding plate 72. The vibration mechanism 73 is arranged on the lower side of the feeding plate 72. The baffle 74 is set to a flexible material and is arranged on one side of the lower edge of the feeding plate 72. A material passing gap is formed between the baffle 74 and the lower edge, and the lower end of the baffle 74 is lower than the lower edge.

[0055] In this embodiment, the lotus seeds are discharged by the vibration of the vibration mechanism 73. Specifically, the lotus seeds that fall from the discharge plate 72 may not fall accurately into the grooves, which may cause some lotus seeds to pile up or fall. Therefore, a flexible baffle 74 is provided at the end of the discharge plate 72, and a space is formed between the baffle 74 and the lower edge of the discharge plate 72 as a temporary storage space for the lotus seeds, so as to control the lotus seeds to fall into each trough 23 in an orderly manner. Preferably, the two sides of the baffle 74 are wrapped around the two sides of the discharge plate 72, thereby preventing the lotus seeds from falling from the side, and there is a gap between the first conveyor belt 21 and the baffle 74, so that the lotus seeds that enter the grooves can move smoothly with the first conveyor belt 21, and the lotus seeds that fail to fall into the grooves are blocked in the gap by the baffle 74, and only after falling into the trough 23, they will be driven to move by the first conveyor belt 21.

[0056] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the present invention.
