Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of shrimp processing, in particular to an automatic reversing adjusting feed tail shearing device and an automatic shrimp peeling machine. BACKGROUND
[0002] In order to realize efficient and accurate shrimp processing, an automatic shrimp peeling machine is usually used to realize the functions of shrimp positioning, tail shearing, shell peeling, and intestine cleaning.
[0003] In the automatic shrimp peeling machine, tail shearing (usually referring to the tail fan part of the shrimp) is a key step that requires precise positioning and efficient execution. During the processing, the tail direction needs to be kept consistent, and the shrimp body is clamped to ensure that the shrimp body does not shake during tail shearing, so as to avoid waste of shrimp meat.
[0004] In actual operation, parallel clamps are usually used to clamp the shrimp body, and a rotating blade is used to cut the tail fan. However, since the shrimp body (especially the soft shell part of the abdomen) is soft, hard clamping will cause the shrimp body to collapse, thereby affecting the integrity and quality of the finished product.
[0005] To this end, a flexible clamping method can be used to fix the shrimp body during shearing. The shrimp body is clamped by air cushions or sponges, which can avoid bruising the shrimp body. However, since the tail fan of the shrimp tail is a chitinous shell with high hardness, during tail fan shearing, the shrimp body may be displaced in the horizontal and vertical directions due to the shearing force, resulting in misalignment of the cutting position and incomplete tail fan shearing or the problem of shrimp meat being cut. SUMMARY
[0006] The present application aims to provide an automatic reversing adjusting feed tail shearing device and an automatic shrimp peeling machine to solve the problems raised in the background.
[0007] To achieve the above-mentioned purpose, the present application provides the following technical solution: an automatic reversing adjusting feed tail shearing device, comprising: a machine table, and a fixed plate and a fixed rod fixed on the machine table, the fixed plate being provided with a reversing feeding assembly; further comprising: a rotating sleeve rotatably installed on the machine table, the rotating sleeve being fixed at one end with a rotating disc, and the fixed rod being fixed at one end with a fixed disc; a clamping plate rotatably installed on the rotating disc, the clamping plate being symmetrically arranged and being circumferentially equidistantly distributed with multiple groups, the rotating disc being provided with a yaw control mechanism connected with the clamping plate, the yaw control mechanism being capable of adjusting the yaw angle of the two clamping plates when the rotating disc rotates, so as to perform clamping and pushing away actions on the shrimp to be processed; a shearing mechanism provided on the fixed disc for performing shearing action on the shrimp tail.
[0008] As a further scheme of the present application: the reversing feeding assembly comprises a rotating adjusting disc rotatably mounted on the machine table, a first air cylinder fixed on the fixed plate, and a push plate fixed on the telescopic end of the first air cylinder.
[0009] As a further scheme of the present application: the deflection control mechanism comprises a plurality of guide rails fixed on the rotating disc and distributed at equal intervals in a circle, a sliding plate slidably mounted in the guide rails, a circular arc groove formed on the sliding plate, and a limiting column fixed on the clamping plate and slidably fitted in the circular arc groove; and a guide assembly and a guide component arranged on the fixed disc and connected with the sliding plate for guiding the sliding plate to slide along the guide rails in a radial direction.
[0010] As a further scheme of the present application: the guide assembly comprises a guide column fixed in the guide rail and penetrating through the sliding plate, and a first spring sleeved on the guide column and abutting against the guide rail and the sliding plate at two ends thereof.
[0011] As a further scheme of the present application: the guide component comprises a guide groove formed on the fixed disc, and a supporting column fixed on the sliding plate and slidably fitted in the guide groove.
[0012] As a further scheme of the present application: the shearing mechanism comprises a sliding groove formed on the fixed disc, a sliding block slidably mounted in the sliding groove, and a supporting rod fixed on the sliding block; and an elastic assembly and a pushing assembly arranged on the fixed disc and connected with the supporting rod.
[0013] As a further scheme of the present application: the elastic assembly comprises a sliding sleeve slidably mounted on the supporting rod and arranged in a symmetrical manner, a cutting knife fixed on the sliding sleeve, and a second spring sleeved on the supporting rod and abutting against the sliding sleeve and the sliding block at two ends thereof.
[0014] As a further scheme of the present application: the pushing assembly comprises a second air cylinder fixed on the fixed disc, a connecting plate fixed on the telescopic end of the second air cylinder, and a connecting rod hingedly connected with the sliding sleeve and hingedly connected with the connecting plate.
[0015] As a further scheme of the present application: the machine table is rotatably mounted with a pair of symmetrical pulleys, a conveying belt is sleeved on the pulleys, a partition plate and a limiting plate are fixed on the conveying belt, and a plurality of limiting plates are distributed at equal intervals in a circle.
[0016] An automatic shrimp tail shearing device with automatic reversing and adjusting functions.
[0017] Compared with the prior art, the present application has the beneficial effects that: the present application can realize automatic shearing processing of shrimp tails through multi-station simultaneous operation when automatically adjusting the direction of the shrimp tail. Specifically, the direction of the shrimp tail is adjusted by the reversing feeding assembly, so that the shrimp tail always faces the direction of the rotating disc. The reversing feeding assembly pushes the shrimp onto the rotating disc and between the two clamping plates. Under the action of the deflection control mechanism, the two clamping plates are in an open state to ensure that the shrimp can smoothly enter. At this time, the angle of the rotating disc is adjusted, so that the clamping plates move to the corresponding station, and the deflection control mechanism adjusts the included angle between the clamping plates to clamp the shrimp body and make the shrimp tail extend out of the two clamping plates. When the clamping is completed, the shearing mechanism shears the shrimp tail. When the shearing is completed, the rotating disc continues to rotate, and when it rotates to a specified position, the deflection control mechanism controls the clamping plates to continue to deflect to eject the processed shrimp. When the rotating disc rotates one circle, the clamping plates return to the initial position, and the above steps are repeated, thereby realizing integrated operation of automatic clamping, shearing and ejecting of the shrimp.
[0018] The two clamping plates form a V-shaped structure with both ends open. Since the shrimp abdomen to the shrimp tail position of the shrimp body is in a reduced state, and the shrimp tail fan itself is in an open state and located outside the two clamping plates, the tapered structure of the V-shaped structure naturally fits the shrimp body, and multiple-point contact can be achieved without accurate positioning, and the shrimp tail is outside the V-shaped structure, so that the shrimp is clamped and fixed by using the obstruction formed by the structure of the shrimp body and the open shrimp tail fan, to prevent the shrimp body from being crushed (especially the soft shell part of the abdomen) due to hard clamping of the shrimp body, which affects the integrity and quality of the finished product. When the end of the V-shaped structure acts on the position close to the shrimp tail, it can also control the further opening of the shrimp tail fan by extruding the shrimp abdomen, so as to facilitate subsequent shearing.
[0019] The two cutting knives form an inverted V-shaped structure opposite to the V-shaped structure. The inverted V-shaped structure and the natural open state of the shrimp tail fan form a complement, and the cutting edges cut in from both sides at the same time when shearing, which has the effect of gathering the shrimp tail fan, thereby covering the root arc of the tail fan and reducing the cutting blind area. At the same time, the shearing force generated by the two cutting knives moving towards each other cancels each other out, avoiding the deviation of the shrimp body caused by unilateral force. The inverted V-shaped structure body and the V-shaped structure clamp form an "X-shaped" cross layout, which physically isolates the shrimp body from the cutting area and prevents accidental injury to the shrimp body.

DETAILED DESCRIPTION
[0031] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.
[0032] In addition, the elements in the present application are referred to as "fixed to" or "disposed on" another element, which can be directly on another element or can have a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or can have a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.
[0033] Please refer to Figures 1-10 In the embodiments of the present application, a feed shearing shrimp tail device with automatic reversing adjustment includes a machine table 1, a fixed plate 2 and a fixed rod 8 fixed on the machine table 1, and a reversing feed assembly provided on the fixed plate 2. It also includes a rotating sleeve 6 rotatably installed on the machine table 1, a rotating disc 7 fixed at one end of the rotating sleeve 6, and a fixed disc 9 fixed at one end of the fixed rod 8. A clamping plate 10 is rotatably installed on the rotating disc 7, and the clamping plate 10 is symmetrically arranged and circumferentially equidistantly distributed with multiple groups. A yaw control mechanism connected with the clamping plate 10 is provided on the rotating disc 7, which can adjust the yaw angle of the two clamping plates 10 when the rotating disc 7 rotates, so as to perform clamping and pushing away actions on the shrimp to be processed. A shearing mechanism is provided on the fixed disc 9 for performing shearing action on the shrimp tail. Symmetrically arranged pulleys are rotatably installed on the machine table 1, a conveying belt 26 is sleeved on the pulleys, a partition plate 2601 and a limiting plate 27 are fixed on the conveying belt 26, and the limiting plate 27 is circumferentially equidistantly distributed with multiple groups.
[0034] Specifically, when processing the shrimp tail, it is usually necessary to cooperate with the feeding machine to operate synchronously. The feeding machine can automatically deliver the shrimp to be processed to the reversing feeding assembly one by one in sequence. The machine table 1 is provided with a camera, which can capture the direction of the shrimp tail, and adjust the direction of the shrimp tail through the reversing feeding assembly, so that the shrimp tail always faces the direction of the rotating disc 7. When the adjustment is completed, the reversing feeding assembly pushes the shrimp onto the rotating disc 7 and between the two clamping plates 10. Under the action of the deflection control mechanism, the two clamping plates 10 are in an open state, ensuring that the shrimp can enter smoothly. When the feeding is completed, the rotating sleeve 6 controls the rotating disc 7 to rotate, thereby driving the clamping plate 10 to move through the deflection control mechanism, so that the included angle between the two clamping plates 10 gradually decreases to clamp the shrimp body and make the shrimp tail extend out of the two clamping plates 10. When the clamping is completed, the rotating disc 7 continues to rotate and guides the shrimp to move to the shrimp tail shearing position through the clamping plate 10. Under the action of the shearing mechanism, the shrimp tail is sheared. When the shearing is completed, the rotating disc 7 continues to rotate and, when it rotates to a specified position, the clamping plate 10 continues to deflect through the deflection control mechanism to eject the processed shrimp. When the rotating disc 7 rotates one circle, the clamping plate 10 returns to the initial position, and the above steps are repeated, thereby realizing the integrated operation of automatic clamping, shearing and ejecting of the shrimp.
[0035] Please refer to Figure 1 , Figure 2 , the reversing feeding assembly comprises a direction adjusting disc 5 rotatingly installed on the machine table 1, the first air cylinder 3 is fixed on the fixed plate 2, and the push plate 4 is fixed on the extension end of the first air cylinder 3.
[0036] In detail, the direction adjusting disc 5 cooperates with the feeding machine. When the feeding machine delivers a single shrimp to the direction adjusting disc 5, the camera can capture the direction of the shrimp tail and the length of the shrimp body, and according to the collected data, the direction adjusting disc 5 is controlled to rotate by the motor (not shown in the figure), so that the shrimp tail faces the direction of the rotating disc 7. When the adjustment is completed, the first air cylinder 3 works and controls the push plate 4 to move towards the direction of the rotating disc 7. The push plate 4 is provided in an open shape, and the opening direction faces the direction of the shrimp head. Therefore, under the action of the push plate 4, the shrimp can be pushed to move towards the direction of the rotating disc 7 and move between the two clamping plates 10. When the shrimp tail completely extends between the two clamping plates 10, the first air cylinder 3 controls the push plate 4 to reset, and the above steps are repeated, thereby realizing the automatic adjustment of the shrimp tail and the automatic feeding.
[0037] Preferably, through the automatic capture of the camera, the direction of the shrimp tail can be kept consistent, and the extension amount of the first air cylinder 3 can be controlled according to the length of the shrimp body, so that when different sizes of shrimps are dealt with, the shrimp tail can always be located outside the two clamping plates 10, to ensure the accuracy of subsequent cutting of the shrimp tail.
[0038] Please refer to Figures 1-4 ,Figures 6-8 The deflection regulating mechanism comprises a plurality of guide rails 12 fixed on the rotating disc 7 and distributed at equal intervals in a circle, a sliding plate 13 slidably mounted in the guide rails 12, a circular-arc groove 1301 formed on the sliding plate 13, and a limiting column 11 fixed on the clamping plate 10 and slidably fitted in the circular-arc groove 1301; further comprising a guide assembly and a guide component provided on the fixed disc 9 and connected with the sliding plate 13, for guiding the sliding plate 13 to slide along the guide rails 12 in a radial direction, the guide assembly comprising a guide column 14 fixed in the guide rail 12 and penetrating through the sliding plate 13, and a first spring 15 sleeved on the guide column 14, two ends of the first spring 15 being respectively abutted against the guide rail 12 and the sliding plate 13, and the guide component comprising a guide groove formed on the fixed disc 9, and a supporting column 16 fixed on the sliding plate 13 and slidably fitted in the guide groove.
[0039] Please refer to Figure 4 It should be noted that the guide groove can be divided into six segments, i.e., a first ring groove 901, a first inclined groove 902, a second ring groove 903, a straight groove 904, a third ring groove 905, and a second inclined groove 906, the distances between the first ring groove 901, the second ring groove 903, and the third ring groove 905 and the center of the circumference of the fixed disc 9 gradually increase, and the first ring groove 901, the first inclined groove 902, the second ring groove 903, the straight groove 904, the third ring groove 905, and the second inclined groove 906 are sequentially connected with each other.
[0040] Please refer to Figure 3, the clamping plates 10 are symmetrically arranged, and are provided with four groups, the two clamping plates 10 in the same group are arranged in a slotted manner, and the slots of the two clamping plates 10 are in a staggered state. In this regard, when the two clamping plates 10 are deflected, they can cross each other without interfering with each other. The rotating disc 7 is provided with four stations, which are a feeding station, a clamping station, a shearing station and an ejection station. The clamping plate 10 of the feeding station is described as the starting point. In the initial state, the supporting column 16 is located in the first ring groove 901, so that the sliding plate 13 is located at the end of the stroke close to the center of the rotating sleeve 6, and is located at the end of the stroke close to the rotating sleeve 6 side of the guide rail 12. The extension of the first spring 15 in the natural state is greater than the length of the guide rail 12. In this regard, the first spring 15 is in a pre-compressed state, and under the action of the sliding plate 13, the compression of the first spring 15 is maximum. The first spring 15 always provides a pushing force to the sliding plate 13 in the direction away from the rotating sleeve 6. The sliding plate 13 will control the maximum distance between the two limiting columns 11 through the circular arc groove 1301, so that the two clamping plates 10 are in an open state, and the included angle between the two clamping plates 10 is in a maximum state. When the shrimp tail needs to be sheared, the two clamping plates 10 are at the maximum opening angle. In this regard, the clamping plate 10 will not affect the normal pushing of the shrimp. Under the action of the first air cylinder 3 and the push plate 4, according to the length of the shrimp body, the shrimp is pushed between the two clamping plates 10, and the shrimp tail is just outside the two clamping plates 10. At this time, the rotating sleeve 6 rotates, thereby driving the rotating disc 7 to rotate. Since the angle of the fixed disc 9 does not change, the rotating disc 7 will drive the sliding plate 13 to move through the guide rail 12, so that the supporting column 16 slides along the first ring groove 901. When the supporting column 16 is separated from the first ring groove 901 and enters the first inclined groove 902, the sliding plate 13 will move along the length direction of the guide rail 12 and move away from the rotating sleeve 6, so that the first spring 15 is elastically released. The sliding plate 13 also drives the circular arc groove 1301 to move, so that the distance between the two limiting columns 11 is reduced, so that the two clamping plates 10 are deflected towards each other.When the support column 16 is disengaged from the first inclined groove 902 and moves into the second ring groove 903, the rotating sleeve 6 is just rotated by 90°, and the two clamping plates 10 can clamp the shrimp body. At this time, the two clamping plates 10 form a V-shaped structure with both ends open. Since the position from the shrimp abdomen to the shrimp tail of the shrimp body is in a tapering state, and the shrimp tail fan itself is in an open state and located outside the two clamping plates 10, the tapering structure of the V-shaped structure naturally fits the shrimp body, and multiple-point contact can be achieved without accurate pre-positioning, and the shrimp tail is outside the V-shaped structure, so as to use the obstruction formed by the structure of the shrimp body and the open shrimp tail fan to clamp and fix the shrimp, so as to prevent the shrimp body from being crushed (especially the soft shell part of the abdomen) due to the hard clamping of the shrimp body, which affects the integrity and quality of the finished product. When the end of the V-shaped structure acts on the position close to the shrimp tail, it can also control the further opening of the shrimp tail fan by extruding the shrimp abdomen, so as to facilitate subsequent shearing; please refer to; Figure 6When the shrimp body is clamped, the sleeve 6 continues to rotate until the rotating disc 7 rotates 90°, and the clamping plate 10 just moves to the shearing station. In this process, the support column 16 is always in the second ring groove 903, ensuring that the position of the sliding plate 13 does not change, so as to ensure that the deflection angle of the clamping plate 10 does not change. At this time, the shearing mechanism can perform shearing action on the shrimp tail fan. When the shrimp tail fan is subjected to shearing force, the inclined surface of the V-shaped structure formed by the two clamping plates 10 can decompose the shearing reaction force into transverse extrusion force and longitudinal constraint force, thereby inhibiting the transverse shaking and longitudinal displacement of the shrimp body. The contact surface of the V-shaped structure increases the stress area, which can reduce the local pressure compared with point clamping, thereby preventing the collapse of the soft shell of the shrimp abdomen. Since the shrimp tail fan is located outside the V-shaped structure and is in an open state, the shearing mechanism can shear the shrimp tail fan comprehensively, thereby preventing the residue of the shrimp tail fan; after the shrimp tail fan is sheared, the remaining part is completely placed between the two clamping plates 10. At this time, the rotating sleeve 6 continues to rotate until the rotating disc 7 rotates 90° again, and the clamping plate 10 moves to the ejection station. In this process, the support column 16 slides along the second ring groove 903. When the clamping plate 10 is located at the ejection station, the support column 16 just moves to the connected position of the second ring groove 903 and the straight groove 904. At this time, the first spring 15 is quickly elastically released, and the sliding plate 13 is pushed to move away from the rotating sleeve 6, so as to control the two clamping plates 10 to quickly deflect towards each other through the circular arc groove 1301 and the limiting column 11. The two clamping plates 10 will cross each other to eject the shrimp. When the support column 16 moves to the connected position of the straight groove 904 and the third ring groove 905, the sliding plate 13 reaches the end of the stroke. The ejected shrimp will move to the conveying belt 26 and be located between the two limiting plates 27, and be limited by the partition plate 2601 to prevent the shrimp from separating from the conveying belt 26 under the action of inertia. When the shrimp is ejected, the rotating sleeve 6 continues to rotate, so that the support column 16 slides along the third ring groove 905 and enters the second inclined groove 906. Under the action of the second inclined groove 906, the sliding plate 13 moves towards the initial position until the support column 16 is separated from the second inclined groove 906 and returns to the first ring groove 901. When the rotating sleeve 6 rotates 90° again, the clamping plate 10 returns to the initial position. In summary, when the rotating sleeve 6 rotates one circle, the clamping plate 10 will move from the feeding station to the clamping station, the shearing station, the ejection station in turn, and finally return to the feeding station. The other three groups also operate in the same way. In this way, under the action of the four clamping plates 10, the subsequent rotating sleeve 6 rotates 90°, and a shrimp is processed and pushed to the conveying belt 26. The pulley also rotates intermittently when the rotating sleeve 6 rotates, to control the intermittent movement of the conveying belt 26, so that the adjacent two limiting plates 27 load the processed shrimp in turn and convey the shrimp to the subsequent processing equipment.
[0041] Please refer toFigure 1 、 Figure 2 、 Figures 4-6 、 Figure 9 、 Figure 10 The shearing mechanism comprises a sliding groove 17 formed on the fixed disc 9, a sliding block 18 slidingly installed in the sliding groove 17, and a supporting rod 19 fixed on the sliding block 18; further comprises an elastic assembly and a pushing assembly arranged on the fixed disc 9 and connected with the supporting rod 19, the elastic assembly comprises two sliding sleeves 20 symmetrically arranged and slidingly installed on the supporting rod 19, and cutting knives 25 are fixed on the sliding sleeves 20, a second spring 21 is sleeved on the supporting rod 19, and two ends of the second spring 21 are respectively in abutment with the sliding sleeves 20 and the sliding block 18, and the pushing assembly comprises a second air cylinder 22 fixed on the fixed disc 9, a connecting plate 23 fixed on the extension end of the second air cylinder 22, and a connecting rod 24 hinged on the sliding sleeves 20 and the connecting plate 23.
[0042] Further, in the initial state, the extension of the second air cylinder 22 is the largest, under the action of the connecting plate 23 and the connecting rod 24, the sliding block 18 is located at the end of the stroke of the sliding groove 17 close to the rotating sleeve 6, and the two sliding sleeves 20 are respectively located at the end of the stroke on both sides of the supporting rod 19, so that the distance between the two sliding sleeves 20 and the sliding block 18 is the largest, and the extension of the second spring 21 in the natural state is greater than the maximum distance between the sliding sleeves 20 and the sliding block 18, so the second spring 21 is in a pre-compressed state and always provides a pushing force for the sliding sleeves 20 to move away from the sliding block 18, at this time, the distance between the two cutting knives 25 is the largest, and the cutting knives 25 are in a dislocation state with the clamping plate 10; when the clamping plate 10 drives the shrimp to move to the shearing station, at this time, the second air cylinder 22 controls the connecting plate 23 to move away from the rotating sleeve 6, thereby driving the sliding sleeves 20 to move through the connecting rod 24, and because the second spring 21 always provides a pushing force for the sliding sleeves 20, the sliding sleeves 20 will first drive the sliding block 18 to move through the supporting rod 19, so that the sliding block 18 moves along the length direction of the sliding groove 17, when the sliding block 18 moves to the end of the stroke on the other side of the sliding groove 17, the sliding block 18 no longer moves, at this time, the two cutting knives 25 are located at the same vertical position of the shrimp tail, the second air cylinder 22 continues to move, and the connecting rod 24 controls the two sliding sleeves 20 to move towards each other, so that the two cutting knives 25 move towards each other and compress the second spring 21; please refer to Figure 6Since the two cutting knives 25 are symmetrically and obliquely arranged, the two cutting knives 25 form an inverted V-shaped structure opposite to the V-shaped structure, the inverted V-shaped structure is complementary to the natural opening state of the shrimp tail fan, the cutting edges cut in from both sides at the same time when shearing, which has the effect of gathering the shrimp tail fan, thereby covering the arc at the root of the tail fan, reducing the cutting blind area, at the same time, the shearing force generated by the movement of the two cutting knives 25 towards each other cancels each other out, avoiding the deviation of the shrimp body caused by unilateral force, the inverted V-shaped structure body and the V-shaped structure clamp form an "X-shaped" cross layout, which physically isolates the shrimp body from the cutting area and eliminates the injury to the shrimp body; after the cutting is completed, the second cylinder 22 controls the reset of the connecting plate 23 and the connecting rod 24, at this time, the elastic release of the second spring 21 makes the two sliding sleeves 20 move towards each other first, until the distance between the two sliding sleeves 20 reaches the maximum, then the sliding block 18 is pushed towards the initial position, until the sliding block 18 returns to the initial position, repeat the above steps, so as to realize the automatic removal of the shrimp tail fan.
[0043] Wherein, the rotating disc 7 is formed with a through slot, which cooperates with the position of the shrimp tail fan, after the shrimp tail fan is cut, it can be discharged through the through slot, so as to prevent the shrimp tail fan from accumulating on the rotating disc 7 after cutting, which affects the subsequent shearing.
[0044] An automatic shrimp stripping machine comprises the automatic reversing adjusting shrimp tail shearing device.
