Description

Technical Field

[0001] The present invention relates to the technical field of crayfish production, and specifically relates to a full-automatic crayfish tail peeling production device. Background Art

[0002] With the development of the catering industry in recent years, crayfish has become a popular food. In order to solve the problem of low efficiency of manual crayfish shelling, people will use professional equipment to replace manual separation of the shrimp head and shrimp tail; the reason for removing the shrimp head of crayfish is that a large amount of excrement, bacteria and even heavy metals are accumulated in the head of crayfish. After removing the head, cooking is safer. In addition, crayfish without heads can reduce volume and occupy less space, so that they can be more effectively packaged and transported, reducing logistics costs;

[0003] Moreover, the existing catering industry prefers to buy crayfish tails with heads removed but shrimp tail shells retained, because the shrimp tail shells can protect the shrimp meat from the drying effect of direct freezing and prevent the meat from becoming dry and firewood; the shrimp shell is like a natural protective layer, which helps to lock in the moisture in the meat and can keep the shape and integrity of the shrimp meat during cooking; therefore, the existing crayfish tail peeling devices are only used to peel the shrimp heads of crayfish;

[0004] Some technical solutions for crayfish head removal devices have also emerged in the prior art. For example, a Chinese patent with the publication number CN111685161B discloses a crayfish head and shell removal device, which includes a frame, a shrimp body conveying mechanism, a shrimp head cutting mechanism and a lobster positioning mechanism. There are a feeding station and a cutting station on the frame; the shrimp body conveying mechanism is arranged on the frame to convey the crayfish from the feeding station to the cutting station; the shrimp head cutting mechanism is arranged on the frame and located at the cutting station to cut the crayfish; the lobster positioning mechanism is arranged on the frame to fix the crayfish on the shrimp body conveying mechanism so as to facilitate the crayfish to be conveyed to the shrimp head cutting mechanism for shrimp head cutting; the present invention can realize the automatic cutting of the head and shell of crayfish, with fast processing speed and high efficiency, can effectively save manpower, and can ensure the processing quality of the crayfish head and shell;

[0005] However, in the actual application process of this technical solution, although the cutting efficiency is relatively high, the feeding link still relies on manual or mechanical equipment to pick up crayfish one by one and place them on the positioning mechanism; the traditional manual or semi-mechanical grasping method is limited by the physical strength and experience of the operator; for example, manual feeding not only consumes time, but also easily causes problems such as uneven placement and non-standard operation, resulting in low overall feeding efficiency and greatly affecting the efficiency of crayfish tail peeling; the use of fully automated robotic arms, although it can improve the feeding speed, its high cost and maintenance requirements are factors restricting its widespread application in small and medium-sized enterprises;

[0006] In view of this, in order to overcome the above technical problems, the present invention proposes a fully automatic crayfish tail peeling production device, which solves the above technical problems. Summary of the Invention

[0035] The drive plate 23, and a plurality of drive bars 211 are provided; the drive plate 23 is located between two adjacent drive bars 211; the drive plate 23 is arranged in an L shape; the drive plate 23 is fixedly connected to the conveying frame 2; the surface of the drive plate 23 is surrounded by a drive belt 231; a drive rod 232 is arranged below the drive plate 23; the drive rod 232 is used to drive the drive belt 231 to rotate; the drive rod 232 and the drive motor 22 are connected by a belt 233 for belt drive connection; a push plate 24 is fixedly connected to the outer ring wall of the drive belt 231.

[0036] As an implementation manner of the present invention, a transmission gear 234 is fixedly connected to the surface of the drive rod 232; a meshing groove 235 is formed in the inner ring wall of the drive belt 231; the drive belt 231 is meshed and driven with the transmission gear 234 through the meshing groove 235 in the inner ring wall.

[0037] As an implementation manner of the present invention, a baffle 25 is fixedly connected to the side wall of the drive plate 23; the baffle 25 is inclined; both the baffle 25 and the drive bar 211 are made of PTFE material; the baffle 25 is in sliding contact with the upper end surface of the drive bar 211.

[0038] As an implementation manner of the present invention, two groups of push plates 24 are arranged on the surface of the same drive belt 231; the two groups of push plates 24 are parallel to each other; a rubber belt 241 is arranged between the two groups of push plates 24; through grooves 242 are formed in the upper end surface of the push plate 24; the rubber belt 241 is slidably connected in the through grooves 242; both ends of the rubber belt 241 are fixedly connected to the lower end surface of the push plate 24 through connecting springs 243;

[0039] During operation, when the existing crayfish are being loaded, it is still necessary to manually or mechanically pick up the crayfish one by one and place them on the positioning mechanism; the traditional manual or semi-mechanical grasping method is limited by the physical strength and experience of the operator; for example, manual loading not only consumes time, but also easily causes problems such as uneven placement and non-standard operation, resulting in a low overall loading efficiency and greatly affecting the efficiency of peeling crayfish tails; the use of a fully automated robotic arm can improve the loading speed, but its high cost and maintenance requirements are factors restricting its wide application in small and medium-sized enterprises;

[0040] In this regard, the present invention sets the transmission bar 211 and the transmission belt 231 so that the shrimp head of the crayfish that falls between two adjacent transmission bars 211 is clamped by the two adjacent transmission bars 211; and is transported to the transmission plate 23, so that the transmission belt 231 at the transmission plate 23 transports the crayfish to rise, so that the shrimp heads of the rising crayfish are all facing upward until the crayfish falls into the storage groove 121 of the cutting board 12. Compared with the traditional manual or semi-mechanical grasping and feeding method, the present invention not only has high feeding efficiency, but also reduces the labor intensity of operators, and avoids problems such as uneven placement and irregular operation; compared with the use of a fully automatic mechanical arm, the present invention has lower costs and maintenance requirements, and can improve the efficiency of crayfish tail peeling in small and medium-sized enterprises;

[0041] Before peeling the tails of crayfish, dead shrimps, old shell shrimps and impurities need to be removed first, and then the crayfish of different sizes are graded through a screening machine, and then each grade of crayfish after grading is uniformly cleaned. The crayfish needs to be cleaned three times. The first and second steps are used to clean the mud and dirt on the surface of the shrimp body. After the third step, the cleaned crayfish of the same size are immediately transported to the steamer for steaming, and then quickly transported to the cooling pool for cooling after steaming; because the crayfish is alive before steaming, its muscles have a certain elasticity; when they are heated, the two proteins actin and myosin in the muscle will have a contraction reaction, which is similar to the contraction of meat fibers during boiling; so after the crayfish is cooked, the whole body presents a curled shape; at this time, a conveying device is used to convey the cooled curled crayfish to the end of the conveying rack 2 away from the body 1;

[0042] In the initial state, there are twelve transmission bars 211. The upper end of the transmission bar 211 is a semi-circular curved surface. Therefore, when the crayfish lands on the transmission bar 211, the crayfish will slide along the semi-circular curved surface at the upper end of the transmission bar 211 and fall between two adjacent transmission bars 211. By setting the distance between two adjacent transmission bars 211 to be the width of the crayfish's tail, since the volume of the crayfish's head is larger than that of the tail, and the distance between two adjacent transmission bars 211 is less than the width of the head, when the crayfish lands on the upper end of the transmission bar 211 of the conveying frame 2, the tail of the crayfish that slides between two adjacent transmission bars 211 will pass through the gap between two adjacent transmission bars 211, while the head is blocked by the transmission bar 211, so that the crayfish is clamped between two adjacent transmission bars 211. At this time, control the driving motor 22 to operate, so that the driving motor 22 can drive the transmission roller 21 to rotate, so that the transmission roller 21 drives the transmission belt 231 to rotate, so that two adjacent transmission belts 231 drive the clamped crayfish to move in the direction close to the transmission plate 23. Since when the driving motor 22 operates, the driving motor 22 can drive the driving rod 232 to rotate synchronously through the belt 233. Since the transmission gear 234 is fixedly connected to the surface of the driving rod 232, and the teeth of the transmission gear 234 are engaged with the engaging groove 235 on the inner wall of the transmission belt 231. So that the driving rod 232 can drive the transmission belt 231 to operate through the transmission gear 234, so that the transmission belt 231 drives the rubber belt 241 to move synchronously through the pushing plate 24 fixedly connected to the outer wall. When the transmission bar 211 conveys the crayfish to the transmission plate 23, because the transmission plate 23 is set to be L-shaped, the upper end surface of the L-shaped transmission plate 23 is horizontally arranged, and the side wall away from the machine body 1 is inclined. When the crayfish is conveyed to the transmission plate 23, the curled tail of the crayfish first comes into sliding contact with the transmission belt 231 of the transmission plate 23. As two adjacent transmission bars 211 drive the clamped head to continue to approach the transmission belt 231, the crayfish continuously inclines in the direction close to the transmission belt 231 until the crayfish comes into sliding contact with the transmission belt 231. At this time, the crayfish is blocked by the transmission belt 231 and no longer pushed by the transmission bar 211. During the process of the transmission belt 231 rotating around the transmission plate 23, the transmission belt 231 drives the rubber belt 241 to rise along the inclined side wall of the transmission plate 23 through the pushing plate 24, so that the rising rubber belt 241 can pass through between two adjacent transmission bars 211. So that the rising rubber belt 241 pushes the crayfish to rise through the pushing plate 24 fixedly connected to the surface. And baffles 25 are fixedly connected to the side walls on both sides of the transmission plate 23, so that the baffles 25 can block and limit the crayfish, so that the crayfish pushed by the pushing plate 24 can be stably limited between the two baffles 25, avoiding the deflection of the crayfish to one side of the transmission belt 231 due to the shift of the center of gravity, and further avoiding the crayfish falling from the transmission belt 231. So that the conveying effect of the transmission belt 231 on the crayfish is improved;The support rod 212 is provided to support the transmission bar 211 so that the transmission bar 211 can smoothly transport the crayfish.

[0043] Since crayfish that are in contact with the transmission belt 231 by sliding are clamped between two adjacent transmission bars 211, when the curled tail of the crayfish contacts the push plate 24, the tail curls into a curved surface, and the tail also contacts the push plate 24 through the smooth surface of its shell. As a result, the friction coefficient between the push plate 24 and the crayfish tail is small, and the contact area is small; the push plate 24 cannot support the crayfish tail. Therefore, by setting the rubber belt 241, when the crayfish tail contacts the rubber belt 241, the rubber belt supports the crayfish. During the process of the rubber belt 241 supporting the crayfish to rise, the crayfish, due to its own gravity, pushes the rubber belt 241 between two adjacent push plates 24 to stretch downward and bend, so that the two ends of the rubber belt 241 enter the through groove 242, and the two ends of the rubber belt 241 squeeze the connecting spring 243 and approach the push plate 24; until the connecting spring 243 is under the maximum squeezing force, the rubber belt 241 will not stretch. At this time, the curved rubber belt 241 between the two push plates 24 completely lifts and positions the crayfish tail part, which not only ensures that the rubber belt 241 can effectively support the curled tail of the crayfish, but also prevents the crayfish from slipping off the push plate 24, facilitating the stable transportation of the crayfish by the transmission belt 231, ensuring that the crayfish moves synchronously with the transmission belt 231, and thus improving the transportation effect of the transmission belt 231 on the crayfish; as the transmission belt 231 drives the rubber belt 241 to rise, the rubber belt 241 can drive the crayfish to rise, causing the crayfish to move away from the transmission bar 211 until the crayfish rises to the upper end of the transmission plate 23. At this time, the crayfish head faces the machine body 1 and is in a horizontal state, and the transmission belt 231 continues to transport the crayfish in the direction close to the machine body 1; when the crayfish is at the upper end of the transmission plate 23, the gravity of the crayfish no longer exerts a pushing effect on the rubber belt 241, causing the two ends of the rubber belt 241 to reset under the pulling force of the restoring force of the connecting spring 243, so that the rubber belt 241 between the two push plates 24 exerts a push on the crayfish, causing the crayfish to slide on the transmission belt 231 until the rubber belt 241 resets and the crayfish stops sliding; the transmission belt 231 continues to transport the crayfish in the direction close to the machine body 1.

[0044] In the initial state, the storage groove 121 at the upper end of the cutting plate 12 faces the transmission plate 23, so that the conveyor belt 231 conveys the crayfish through the transmission plate 23 near one end of the machine body 1 and drops them into the storage groove 121 at the upper end of the cutting plate 12. The crayfish that fall into the storage groove 121 slide along the storage groove 121 under the action of inertia until the shrimp head touches the machine body 1. At this time, the shrimp head of the crayfish just crosses the cutting groove 122. Control the operation of the hydraulic push rod 131 so that the hydraulic push rod 131 can push the cutter 13 down, and the descending cutter 13 cuts the crayfish in the storage groove 121. Until the cutter 13 is inserted into the cutting groove 122, the shrimp head and shrimp tail of the crayfish are cut and separated. At this time, the crayfish tail peeling is completed. Then control the hydraulic push rod 131 to rise, so that the hydraulic push rod 131 pulls the cutter 13 back to its original position. Then control the operation of the conveying motor 111, so that the conveying motor 111 drives the conveyor belt 11 at the upper end of the machine head to move, and the conveyor belt 11 drives the cutting plate 12 to move synchronously. Until the cutting plate 12 moves to one side of the machine body 1, as the conveyor belt 11 drives the cutting plate 12 to rotate downward, the cutting plate 12 turns downward, so that the crayfish in the storage groove 121 of the cutting plate 12 fall downward under the action of their own gravity. Since the shrimp head and shrimp tail of the crayfish are separated, two collection boxes are placed on this side of the machine body 1, so that the downward falling shrimp heads and shrimp tails can be collected separately. Furthermore, there is no need for an operator to collect the separated shrimp heads and shrimp tails of the crayfish, which not only reduces the labor intensity of the operator, but also improves the collection efficiency of the crayfish. Furthermore, it does not delay the crayfish tail peeling work, improves the efficiency of crayfish tail peeling, and further improves the practical application effect of the present invention.

[0045] As an implementation manner of the present invention, a guide plate 14 is provided on one side of the transmission plate 23 close to the machine body 1; the guide plate 14 is rotatably connected to the conveying frame 2; the guide plate 14 is in sliding contact with the conveyor belt 231; the guide plate 14 is inclined; a baffle 15 is provided on the side of the guide plate 14 away from the transmission plate 23; the baffle 15 is rotatably connected to the machine body 1 through a torsion spring; a magnet 141 is embedded on one side of the guide plate 14 close to the baffle 15; an electromagnetic sheet 151 is embedded on the side of the baffle 15 close to the guide plate 14.

[0046] As an implementation manner of the present invention, a sliding plate 16 is slidably and sealingly connected in the storage groove 121 of the cutting plate 12; the sliding plate 16 is connected to one end of the cutting plate 12 close to the conveying frame 2 through a support spring 161; an electromagnetic plate 162 is embedded at one end of the cutting plate 12 close to the conveying frame 2.

[0047] As an implementation manner of the present invention, a partition plate 17 is provided above the transmission bar 211; the partition plate 17 is fixedly connected to the upper end of the conveying frame 2; a blocking rod 171 is provided between the partition plate 17 and the transmission bar 211; the blocking rod 171 is rotatably connected to the lower end of the partition plate 17; the blocking rod 171 is in sliding contact with the transmission bar 211.

[0048] As an implementation manner of the present invention, the blocking rod 171 is made of PTFE material; a cylindrical groove 172 is opened at the lower end of the blocking rod 171;

[0049] During operation, when the crayfish are conveyed to the guide plate 14 by the transmission plate 23, the crayfish slide downward along the inclined guide plate 14. Since in the initial state, the placement groove 121 at the upper end of the cutting plate 12 is opposite to the end of the guide plate 14 away from the transmission plate 23, the crayfish sliding downward along the inclined guide plate 14 can stably fall into the placement groove 121 at the upper end of the cutting plate 12, enabling the guide plate 14 to play a guiding role between the cutting plate 12 and the transmission plate 23 to ensure that the crayfish can stably fall into the placement groove 121 of the cutting plate 12. When the conveyor belt 231 drives the push plate 24 to the guide plate 14, there is a gap between the conveyor belt 231 and the guide plate 14, and the width of the gap is smaller than the width of the crayfish, so that the push plate 24 moves into the gap between the guide plate 14 and the conveyor belt 231 as the conveyor belt 231 moves. As the push plate 24 continues to rotate downward, the push plate 24 comes into contact with the guide plate 14. Since the lower end face of the guide plate 14 has a rounded corner, the push plate 24 contacts the rounded corner, causing the push plate 24 to push the guide plate 14 to rotate upward through the rounded corner until the push plate 24 contacts the lower end of the guide plate 14, and the push plate 24 makes a sliding contact with the lower end face of the guide plate 14, enabling the push plate 24 to cross over the guide plate 14 through the lower end of the guide plate 14. At this time, the guide plate 14 rotates downward and resets under its own gravity, causing the guide plate 14 to face the conveyor belt 231 again, so that the conveyor belt 231 can continue to convey the crayfish onto the guide plate 14. By setting the baffle 15, the crayfish entering the guide plate 14 can be blocked by the baffle 15 first. At this time, the baffle 15 is pressed tightly against the guide plate 14 under the adsorption force of the magnet 141. As the user controls the electromagnetic sheet 151 to be energized, the electromagnetic sheet 151 generates a magnetic repulsive force on the magnet 141, causing the baffle 15 to rotate downward against the torsion of the torsion spring under the push of the magnetic repulsive force of the magnet 141, so that the baffle 15 no longer blocks the guide plate 14, and the crayfish in the guide plate 14 fall over the baffle 15 into the cutting plate 12 under their own gravity. At this time, the electromagnetic sheet 151 is powered off, causing the baffle 15 to flip upward under the restoring force of the torsion spring. Until the baffle 15 approaches the magnet 141, the magnet 141 adsorbs the baffle 15 and rotates upward quickly until the baffle 15 is pressed tightly against the guide plate 14, causing the baffle 15 to block the crayfish subsequently conveyed onto the guide plate 14, preventing the crayfish from falling into the placement groove 121 again when the cutter 13 cuts the heads of the crayfish in the placement groove 121 of the cutting plate 12 during the crayfish head cutting process, resulting in the inability to effectively cut the heads of the crayfish falling into the cutting plate 12, ensuring the effect of subsequent crayfish head cutting and further improving the practical application effect of the present invention;

[0050] In the initial state, the skateboard 16 is adsorbed by the electromagnetic plate 162 and presses the support spring 161 to move towards one end of the cutting plate 12 close to the conveying rack 2 until the skateboard 16 is located below the guide plate 14. After the crayfish falls into the placement groove 121 of the cutting plate 12, the electromagnetic plate 162 is controlled to power off, so that the skateboard 16 moves in the direction away from the conveying rack 2 under the pushing force of the restoring force of the support spring 161, so that the skateboard 16 pushes the crayfish falling into the placement groove 121 towards the direction close to the cutting groove 122 until the head of the crayfish crosses the cutting groove 122 and contacts the machine body 1, thus avoiding that the crayfish falling from the guide plate 14 cannot effectively slide and cross the cutting groove 122 due to insufficient inertial force, ensuring that the head of the crayfish can effectively cross the cutting groove 122, and further ensuring that the head of the crayfish can be completely cut, so as to improve the effect of removing the head and peeling the tail of the crayfish, and effectively improving the actual application effect of the present invention;

[0051] Since when the crayfish is poured on the conveying rack 2, the crayfish will fall on the transmission strip 211. If the curled crayfish lies on the transmission strip 211 with its head down, it will cause the crayfish to not effectively fall between two adjacent transmission strips 211. Therefore, by setting the blocking rod 171, when the transmission strip 211 drives the crayfish lying on it to the blocking rod 171, the blocking rod 171 can block the crayfish, so that the crayfish deflects under the action of the blocking force, and the center of gravity of the deflected crayfish shifts, so that the crayfish on the transmission strip 211 slides down along the curved end of the transmission strip 211 to between two adjacent transmission strips 211, thus ensuring that two adjacent transmission strips 211 can clamp and convey the head direction of the crayfish, and effectively improving the practicability of the present invention; The blocking rod 171 is made of PTFE material, and the blocking rod 171 is rotatably connected to the lower end of the partition plate 17. The purpose is to reduce the friction between the blocking rod 171 and the crayfish. When the head of the crayfish passes between the two blocking rods 171, the head of the crayfish contacts the blocking rod 171. At this time, the blocking rod 171 rotates under the action of the blocking force, that is, the head of the crayfish pushes the blocking rod 171 to rotate through the blocking force, so that the two blocking rods 171 rotating towards each other can produce a pushing effect on the head, thereby accelerating the head to pass between the two blocking rods 171 and preventing the head from getting stuck between the two blocking rods 171. And a cylindrical groove 172 is opened at the lower end of the blocking rod 171, on the one hand, reducing the production cost of the blocking rod 171, and on the other hand, reducing the gravity of the blocking rod 171 to improve the rotation effect of the blocking rod 171 pushed by the blocking force of the head of the crayfish, so as to enhance the pushing effect of the two rotating blocking rods 171 on the head; effectively improving the actual application effect of the present invention.
