Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food processing, in particular to a lotus root slice screening conveying equipment with anti-adhesion function. BACKGROUND

[0002] In the lotus root slice processing industry, the traditional process usually directly pours a whole barrel of lotus root slices onto a conveyor belt, and then conveys the lotus root slices to the subsequent processing link through the conveyor belt. However, since the lotus root slices have mucilage on the surface and are irregular in shape, they are prone to adhesion and stacking during the conveying process, which causes the lotus root slices to adhere to each other or overlap, affecting the subsequent manual sorting efficiency. At present, enterprises mainly rely on a large number of workers to manually separate the adhered lotus root slices and remove the damaged or incomplete lotus root slices. This method not only has high labor intensity and labor cost, but also has low sorting efficiency, which is difficult to meet the needs of large-scale production.

[0003] The existing conveying equipment is usually an ordinary flat belt conveyor, which lacks anti-adhesion design for the characteristics of lotus root slices, resulting in uneven distribution of lotus root slices during conveying, which affects the smooth progress of subsequent automatic sorting or packaging.

[0004] Patent document No. CN108529183B discloses a food lotus root slice automatic conveying and adhesion prying device, which comprises a lotus root slice prying device and a lotus root slice sorting and separating device. The lotus root slice prying device comprises a prying device frame, an adsorption conveyor belt, a fifth motor, a prying device, and an adsorption device. The lotus root slice sorting and separating device comprises a sorting frame, a sorting conveyor belt, a sorting mechanism, an image sensor, a sorting frame, a transverse sliding frame, a second rodless cylinder, a suction cup, an eleventh cylinder, a sorting conveyor frame, a sorting conveyor belt, a size limiting block, and an infrared sensor.

[0005] In the device, the lotus root slices are conveyed to the adsorption conveyor belt, wherein through holes are provided through the adsorption conveyor belt, and the lotus root slices are adsorbed on the adsorption conveyor belt by the adsorption device through negative pressure adsorption. After passing through the prying device, the overlapped lotus root slices will be pried apart under the action of the rubber rod, thereby reducing the damage rate of the lotus root slices and facilitating the subsequent screening of damaged lotus root slices.

[0006] However, the device only relies on the single action of the fixed rubber rod, which is difficult to adapt to the separation needs of lotus root slices with different adhesion degrees, and may cause incomplete separation of some lotus root slices or damage due to uneven stress. Moreover, it cannot achieve the effect of gradual peeling of the lotus root slices during conveying, increasing the risk of damage to the lotus root slices due to instantaneous stress. SUMMARY

[0039] The cycle poking surface 221 performs flexible peeling on the adhered lotus leaf through a progressive non-rigid lifting contact mode, solves the problem that the traditional equipment cannot effectively separate the overlapped lotus leaf, and significantly reduces the risk of lotus leaf damage caused by rigid poking;

[0040] The whole structure realizes accurate partition, flexible processing and efficient peeling of the lotus leaf during the conveying process, and is especially suitable for lotus leaf screening operation scenes with slight adhesion or overlapping phenomenon.

[0043] As shown in Figure 5 , the poking assembly 22 further comprises two tensioning wheels 2251 laterally slidingly arranged at the two sides of the bracket 21, and an elastic tensioning element 2252 arranged in the bracket 21 and used for elastically abutting the two tensioning wheels 2251 against the inner surface of the circulating poking belt 223.

[0044] The poking assembly 22 further comprises two tensioning wheels 2251 laterally slidingly arranged at the two sides of the bracket 21, which can adjust the tensioning force and position as needed to ensure the tensioning degree and stability of the circulating poking belt 223. The elastic tensioning element 2252 is arranged in the bracket 21 and used for elastically abutting the two tensioning wheels 2251 against the inner surface of the circulating poking belt 223, thereby realizing effective tensioning of the circulating poking belt 223, ensuring that it maintains appropriate tension during operation, avoiding belt slackness or over-tightness, and ensuring the stable movement and poking effect of the circulating poking belt 223.

[0045] As shown in Figure 5 and Figure 10As shown, the material pushing assembly 22 further comprises two upper sliding seats 2253 slidingly arranged on both sides of the support 21, and two tensioning wheels 2251 rotatably arranged on the two upper sliding seats 2253 respectively.

[0046] The material pushing assembly 22 further comprises two upper sliding seats 2253 slidingly arranged on both sides of the support 21, which can be adjusted to move along the horizontal direction, and one tensioning wheel 2251 is rotatably arranged on each of the two upper sliding seats 2253. The two tensioning wheels 2251 are adjusted to slide transversely through the upper sliding seats 2253, and the tensioning wheels 2251 are in contact with the inner surface of the circulating material pushing belt 223 to achieve belt tensioning.

[0047] Meanwhile, the elastic tensioning element 2252 is arranged between the two upper sliding seats 2253 to provide elastic pushing force between the two upper sliding seats 2253, so that the two tensioning wheels 2251 are always elastically pressed towards the inner side of the circulating material pushing belt 223 to achieve automatic tensioning function.

[0048] As shown, Figures 5-8 The material pushing assembly 22 further comprises two adjusting plates 2261 oppositely slidingly arranged in the support 21, an upper adjusting shaft 2262 rotatably arranged in the support 21 and extending along the length direction of the support 21, the circumferential surface of the upper adjusting shaft 2262 is provided with two upper adjusting portions extending along the radial direction thereof, and the two upper adjusting portions are respectively abutted between the two adjusting plates 2261. The elastic tensioning element 2252 is arranged between the adjusting plates 2261 and the upper sliding seats 2253.

[0049] The two adjusting plates 2261 are oppositely slidingly arranged in the support 21 and can move along the horizontal direction to approach or move away from the axis of the upper adjusting shaft 2262, serving as key components for transmitting adjusting force.

[0050] The upper adjusting shaft 2262 is rotatably arranged in the support 21 and extends along the length direction of the support 21. The circumferential surface of the upper adjusting shaft 2262 is provided with two upper adjusting portions protruding along the radial direction (which can be eccentric cam structures or helical lugs), which are respectively abutted with the two adjusting plates 2261.

[0051] When the upper adjusting shaft 2262 is rotated, the radial positions of the two upper adjusting portions change, thereby pushing the two adjusting plates 2261 to produce sliding displacement towards or away from each other. The elastic tensioning element 2252 is arranged between the adjusting plates 2261 and the upper sliding seats 2253. The compression degree of the elastic tensioning element 2252 changes with the change of the position of the adjusting plates 2261, thereby realizing elastic adjustment and automatic compensation of the tensioning wheel 2251. The upper adjusting shaft 2262 rotates the adjusting portion to push the adjusting plate 2261 to slide; the compression amount of the elastic tensioning element 2252 changes; and the tensioning effect of the upper sliding seat 2253 on the tensioning wheel 2251 changes.

[0052] As shown in Figure 5 the inner end of the upper sliding seat 2253 is provided with an upper limiting plate 2254; the bracket 21 is provided with an upper guide rod 2255 extending transversely, the upper guide rod 2255 penetrates the adjusting plate 2261 and the upper limiting plate 2254, and the elastic tensioning element 2252 is sleeved on the upper guide rod 2255.

[0053] The poking assembly 22 comprises two tensioning wheels 2251 which are transversely and slidingly arranged on both sides of the bracket 21 and used for abutting against the inner surface of the circulating poking belt 223; two upper sliding seats 2253 which are slidingly and penetratingly arranged on both sides of the bracket 21, and the two tensioning wheels 2251 are rotatably installed on the two upper sliding seats 2253 respectively; two adjusting plates 2261 which are slidingly arranged in the bracket 21 oppositely; an upper adjusting shaft 2262 which is rotatably arranged in the bracket 21 and extends along the length direction of the bracket 21, and the circumferential surface of the upper adjusting shaft 2262 is provided with two upper adjusting portions extending along the radial direction thereof and abutting between the two adjusting plates 2261 respectively; the inner end of each upper sliding seat 2253 is provided with an upper limiting plate 2254; the bracket 21 is provided with an upper guide rod 2255 extending transversely, the upper guide rod 2255 penetrates the adjusting plate 2261 and the upper limiting plate 2254 in sequence, and the elastic tensioning element 2252 is sleeved on the upper guide rod 2255 and arranged between the adjusting plate 2261 and the upper limiting plate 2254, so as to provide elastic thrust between the two upper sliding seats 2253, thereby making the tensioning wheels 2251 elastically abut against the inner surface of the circulating poking belt 223. By rotating the upper adjusting shaft 2262, the distance between the two adjusting plates 2261 and the axis of the upper adjusting shaft 2262 is adjusted, and then the compression amount of the elastic tensioning element 2252 is adjusted, so as to adjust the tensioning force of the two tensioning wheels 2251 on the circulating poking belt 223, to realize automatic compensation and fine control, and to ensure the tension stability of the circulating poking belt 223 in the running process.

[0054] As shown in Figure 5 the poking assembly 22 further comprises a lower sliding seat 2271 which is slidingly and penetratingly arranged at the top end in the bracket 21, and the poking wheel set 222 is rotatably arranged on the lower sliding seat 2271; and the upper sliding seat 2253 and the inner wall of the bracket 21 at the top end are provided with an elastic buffering element 2273.

[0055] The poking assembly 22 further comprises a lower sliding seat 2271, the top end of which is slidingly arranged in the support 21 and can move up and down relative to the support 21 in the vertical direction to adapt to the change of the poking path or the tension state. The poking wheel set 222 is rotatably arranged on the lower sliding seat 2271 and used to contact the outer surface of the poking belt to realize the conveying or poking effect. The structure enables the poking wheel set 222 to fine-tune the working height according to the position of the lower sliding seat 2271, thereby improving the adaptability and precision of the poking assembly 22.

[0056] In order to improve the stability and impact resistance of the overall system during operation, the elastic buffer element 2273 is arranged between the upper sliding seat 2253 and the top end of the inner wall of the support 21. The elastic buffer element 2273 can provide flexible support and energy absorption when the poking assembly 22 is subjected to vibration, impact or load mutation, effectively slow down the structural impact, prevent mechanical wear or component deviation, and further improve the smoothness and service life of the equipment operation.

[0057] As shown in Figures 6-8 The upper part of the lower sliding seat 2271 is provided with an adjusting port 2272, and the poking assembly 22 further comprises a lower adjusting shaft 2274 which is rotatably arranged in the support 21 and extends along the length direction of the support 21. The circumferential surface of the lower adjusting shaft 2274 is provided with a lower adjusting part extending in the radial direction thereof, and the lower adjusting part abuts against the top end of the adjusting port 2272.

[0058] The upper part of the lower sliding seat 2271 is provided with an adjusting port 2272 which is opened at the top end face thereof and used to realize mechanical contact and position transmission with the adjusting mechanism. The poking assembly 22 further comprises a lower adjusting shaft 2274 which extends along the length direction of the support 21 and is rotatably arranged in the support 21 and can rotate around the axis thereof to realize the adjusting function.

[0059] The circumferential surface of the lower adjusting shaft 2274 is provided with a lower adjusting part protruding in the radial direction thereof, and the lower adjusting part is used to abut against the top end of the adjusting port 2272. By rotating the lower adjusting shaft 2274, the lower adjusting part will displace relative to the top end of the adjusting port 2272 in the form of an eccentric wheel or a spiral cam, thereby changing the distance between the top end of the adjusting port 2272 and the axis of the lower adjusting shaft 2274.

[0060] By means of the above structure, the initial installation height or working starting position of the poking wheel set 222 carried by the lower sliding seat 2271 can be accurately adjusted. The adjusting structure not only simplifies the alignment process of the poking assembly 22 during assembly and maintenance, but also facilitates the quick height matching of the lower poking mechanism 2 according to the tension or thickness of different poking belts, thereby ensuring the poking stability and contact precision.

[0061] AsFigure 5 As shown, the lower sliding seat 2271 is provided with a buffer seat 2275 capable of moving vertically on both sides of the length direction of the support 21, and the poking wheel group 222 includes two buffer groove wheels 2221, which are respectively rotationally connected with the two buffer seats 2275, and abut against the inner surface of the circulating poking belt 223. The top end of the buffer seat 2275 is provided with a spring 2276.

[0062] The lower sliding seat 2271 is provided with a buffer seat 2275 on both sides of the length direction of the support 21, which can move up and down relative to the lower sliding seat 2271 in the vertical direction, and is used to provide flexible support for the poking wheel group 222. The poking wheel group 222 includes two buffer groove wheels 2221, which are respectively located below the circulating poking belt 223 and abut against the inner surface of the poking belt, forming a supporting effect on the poking belt.

[0063] Each buffer groove wheel 2221 is rotationally connected with the corresponding buffer seat 2275 through a rotating shaft structure, so as to keep synchronous rolling during the operation of the poking belt. The top end of each buffer seat 2275 is provided with a spring 2276 element, which is located between the buffer seat 2275 and the lower sliding seat 2271, and can provide a controllable elastic stroke when subjected to external load or material thickness change.

[0064] Based on the above structure, the two buffer groove wheels 2221 can independently ascend and descend in the respective buffer seats 2275, realizing real-time adaptation to the deformation of the lower side of the circulating poking belt 223. In this way, when the circulating poking belt 223 contacts the lotus root slices, the contact surface can be flexibly deformed in the thickness direction, effectively relieving the problem of excessive local pressure caused by uneven contact pressure or irregular shape, so as to better fit the surface of the lotus root slices and avoid damage caused by impact or friction.

[0065] As shown in Figure 6 and Figure 9 The poking mechanism 2 further includes a lock 228 for fixing the rotation angle of the lower adjusting shaft 2274. The lock 228 includes an inner fixed ring 2281 provided at one end of the support 21 and coaxial with the lower adjusting shaft 2274, and the end thereof is provided with tooth grooves distributed in the circumferential direction thereof; a sliding cylinder 2282 in spline connection with one end of the lower adjusting shaft 2274, and provided with an abutment ring at one end, the abutment ring having a rack capable of engaging with the tooth grooves; an outer fixed ring 2283 provided outside the inner fixed ring 2281, and the abutment ring is located between the inner fixed ring 2281 and the outer fixed ring 2283; and a disc spring 2284 sleeved on the sliding cylinder 2282 and located between the outer fixed ring 2283 and the abutment ring.

[0066] A connecting column is provided between the outer fixed ring 2283 and the inner fixed ring 2281.

[0067] One end of the upper adjusting shaft 2262 is also provided with a lock 228 for fixing the angle of the upper adjusting shaft 2262 after adjusting, preventing self-rotation.

[0068] The stirring mechanism 2 also includes a lock 228 for angularly locking the lower adjusting shaft 2274 after completing the height adjustment of the stirring wheel set 222, to prevent self-rotation due to external force or vibration, and to ensure the stability and consistency of the adjustment state.

[0069] The inner fixing ring 2281 is coaxially sleeved on one end of the support 21 and coaxially arranged with the lower adjusting shaft 2274, and the end face is provided with uniformly distributed tooth grooves in the circumferential direction for realizing locking engagement;

[0070] One end of the sliding cylinder 2282 is connected with the lower adjusting shaft 2274 through a spline structure, and can rotate synchronously with the lower adjusting shaft 2274 but can slide in the axial direction. An abutting ring is arranged at one end in the axial direction;

[0071] The abutting ring is integrally arranged with the sliding cylinder 2282, and a rack capable of engaging with the tooth grooves of the inner fixing ring 2281 is arranged on the outer circumference. When the abutting ring is pushed to press against the inner fixing ring 2281 under the action of the disc spring 2284, the rack is embedded in the tooth groove to realize angular locking;

[0072] The outer fixing ring 2283 is arranged around the outside of the inner fixing ring 2281 to form a ring-shaped limiting structure. The abutting ring is located between the inner fixing ring 2281 and the outer fixing ring 2283, and limits the movement range of the sliding cylinder 2282 in the radial direction;

[0073] The disc spring 2284 is sleeved on the sliding cylinder 2282 and located between the outer fixing ring 2283 and the abutting ring, for providing elastic pushing force to the inner fixing ring 2281, so that the abutting ring maintains the locking state with the tooth grooves of the inner fixing ring 2281 when not subjected to external force;

[0074] The connecting column is connected between the outer fixing ring 2283 and the inner fixing ring 2281, for providing positioning and structural reinforcement to avoid misplacement or relative rotation during assembly.

[0075] In the working process, the lotus root slices are carried by the conveying belt 1 and conveyed along the length direction. When the lotus root slices pass through the poking mechanism 2, the circulating poking surface 221 moves in the direction opposite to the conveying direction of the conveying belt 1 and gradually approaches the surface of the conveying belt 1. The flexible circulating poking surface 221 gently pokes the lotus root slices in a progressive non-rigid contact manner, so as to separate the adhered or overlapped lotus root slices. A plurality of poking mechanisms 2 are arranged in sequence along the length direction of the conveying belt 1. The spacing between the circulating poking surfaces 221 and the conveying belt 1 decreases in sequence along the conveying direction, so as to form a multi-stage progressive stripping path. The poking assembly 22 is arranged along the width direction of the conveying belt 1. The poking wheel set 222 and the circulating poking belt 223 are used to realize the partition processing of the full-width area of the conveying belt 1. The driving shaft 23 is driven by the servo motor 224 to drive the circulating poking belt 223 to move. The tensioning wheel 2251 maintains the stable tension of the circulating poking belt 223 through the elastic tensioning element 2252. The upper sliding seat 2253 and the lower sliding seat 2271 adjust the positions through the upper adjusting shaft 2262 and the lower adjusting shaft 2274 respectively. The buffer groove wheel 2221 realizes the flexible contact through the spring 2276.
