Description

Technical Field

[0001] The invention relates to the technical field of crayfish production, in particular to a fully 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 in manual shelling of crayfish, people will use professional equipment to replace manual separation of shrimp heads and shrimp tails; the reason for removing the heads of crayfish is that a large amount of excrement, bacteria and even heavy metals are accumulated in the heads of crayfish. It is safer to cook after removing the heads. In addition, lobsters without heads can reduce their size and take up less space, which can be packaged and transported more efficiently and reduce logistics costs;

[0003] Moreover, the existing catering industry prefers to buy crayfish tails with heads removed but with the tail shells retained, because the tail shells can protect the shrimp meat from being dried out by direct freezing, preventing the meat from becoming dry and tough; the shrimp shell is like a natural protective layer that helps lock in moisture in the meat and maintains the shape and integrity of the shrimp meat during cooking; therefore, the existing crayfish tail peeling device is only used to peel off the crayfish head;

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

[0005] However, in the actual application of this technical solution, although the cutting efficiency is high, the loading process 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 loading is not only time-consuming, but also prone to problems such as uneven placement and irregular operation, resulting in low overall loading efficiency, which greatly affects the efficiency of peeling shrimp tails; and the use of fully automated robotic arms, although it can increase the loading speed, its high cost and maintenance requirements are factors that restrict its widespread application in small and medium-sized enterprises;

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

[0036] Transmission plate 23, the transmission bars 211 are provided with multiple; the transmission plate 23 is located between two adjacent transmission bars 211; the transmission plate 23 is set to be L-shaped; the transmission plate 23 is fixedly connected to the conveyor frame 2; a transmission belt 231 is surrounded by the surface of the transmission plate 23; a driving rod 232 is provided under the transmission plate 23; the driving rod 232 is used to drive the transmission belt 231 to rotate; the driving rod 232 and the driving motor 22 are connected by belt drive through a belt 233; the outer ring wall of the transmission belt 231 is fixedly connected to a push plate 24.

[0037] As an embodiment of the present invention, a transmission gear 234 is fixedly connected to the surface of the driving rod 232; an engagement groove 235 is opened on the inner ring wall of the transmission belt 231; and the transmission belt 231 is meshed with the transmission gear 234 through the engagement groove 235 of the inner ring wall for transmission.

[0038] As an embodiment of the present invention, a baffle 25 is fixedly connected to the side wall of the transmission plate 23; the baffle 25 is tilted; the baffle 25 and the transmission bar 211 are both made of PTFE material; the baffle 25 is in sliding contact with the upper end surface of the transmission bar 211.

[0039] As an embodiment of the present invention, two groups of push plates 24 are provided on the surface of the same transmission belt 231; the two groups of push plates 24 are parallel to each other; a rubber belt 241 is provided between the two groups of push plates 24; a through groove 242 is provided on the upper end surface of the push plate 24; the rubber belt 241 is slidably connected in the through groove 242; the two ends of the rubber belt 241 are fixedly connected to the lower end surface of the push plate 24 by a connecting spring 243;

[0040] When working, the existing crayfish still need to be picked up one by one by manual or mechanical equipment and placed on the positioning mechanism when loading. The traditional manual or semi-mechanical grasping method is limited by the physical strength and experience of the operator. For example, manual loading is not only time-consuming, but also prone to problems such as uneven placement and irregular operation, resulting in low overall loading efficiency, which greatly affects the efficiency of peeling shrimp tails. The use of fully automated robotic arms can increase the loading speed, but its high cost and maintenance requirements are factors that restrict its widespread application in small and medium-sized enterprises.

[0041] 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;

[0042] 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;

[0043] In the initial state, twelve transmission bars 211 are provided, and the upper ends of the transmission bars 211 are semicircular curved surfaces; therefore, when the crayfish falls on the transmission bar 211, the crayfish will slide along the semicircular curved surfaces at the upper ends of the transmission bars 211 and fall between two adjacent transmission bars 211, and 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 the volume of the tail, and the distance between two adjacent transmission bars 211 is smaller than the width of the head, when the crayfish falls on the upper ends of the transmission bars 211 of the conveying rack 2, the crayfish's tail will pass through the gap between the two adjacent transmission bars 211, and the head of the crayfish will be blocked by the transmission bar 211, making the crayfish The lobster is clamped between two adjacent transmission bars 211. At this time, the driving motor 22 is controlled 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 the two adjacent transmission belts 231 drive the held crayfish to move in the direction close to the transmission plate 23; because when the driving motor 22 is running, the driving motor 22 can drive the driving rod 232 to rotate synchronously through the belt 233; because 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 meshing groove 235 of the inner ring 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 passes through the outer ring wall The connected push plate 24 drives the rubber belt 241 to move synchronously; when the transmission bar 211 transports 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 set horizontally, and is inclined away from the side wall of the body 1; when the crayfish is transported to the transmission plate 23, the curled shrimp tail of the crayfish first slides and contacts with the transmission belt 231 of the transmission plate 23, and as the two adjacent transmission bars 211 drive the supported shrimp head to continue to approach the transmission belt 231, the crayfish continues to tilt in the direction of approaching the transmission belt 231 until the crayfish slides and contacts with the transmission belt 231. At this time, the crayfish is blocked by the transmission belt 231 and is no longer pushed by the transmission bar 211. When the transmission belt 231 surrounds the transmission plate 23, the crayfish is pulled back and the transmission belt 231 is pulled back and forth. During the rotation process, 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 between two adjacent transmission bars 211; the rising rubber belt 241 pushes the crayfish to rise through the pushing plate 24 fixedly connected to the surface, and the side walls on both sides of the transmission plate 23 are fixedly connected with baffles 25, so that the baffles 25 can block and limit the crayfish, so that the crayfish pushed by the pushing plate 24 can be stably restricted between the two baffles 25, so as to prevent the crayfish from deflecting to one side of the transmission belt 231 due to the offset of the center of gravity, thereby preventing the crayfish from 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 used to support the transmission bar 211 so that the transmission bar 211 can transport the crayfish stably.

[0044] Since the crayfish in sliding contact with the transmission belt 231 is clamped between two adjacent transmission bars 211, when the curled tail of the crayfish contacts the pushing plate 24, the tail curls up into a curved surface, and the tail contacts the pushing plate 24 through its smooth shell, resulting in a small friction coefficient between the pushing plate 24 and the tail of the crayfish, and a small contact area; the pushing plate 24 cannot provide temperature support for the tail of the crayfish, and a rubber belt 241 is provided to support the crayfish when the tail of the crayfish contacts the rubber belt 241, and the rubber belt 241 is provided to support the crayfish. During the process of supporting the crayfish to rise, the crayfish pushes the rubber belt 241 between the two adjacent pushing plates 24 to stretch and bend downward by its own gravity, so that the two ends of the rubber belt 241 enter the through groove 242, so that the two ends of the rubber belt 241 squeeze the connecting spring 243 and approach the pushing plate 24; until the connecting spring 243 is squeezed to the maximum, the rubber belt 241 will not stretch, at this time, the bent rubber belt 241 between the two pushing plates 24 completely scoops up and limits the crayfish's tail, which not only ensures that the rubber belt 241 can hold the crayfish's curled up The curved shrimp tail can effectively support the crayfish and prevent the crayfish from sliding off the pushing plate 24, so that the transmission belt 231 can stably transport the crayfish and ensure that the crayfish moves synchronously with the transmission belt 231, thereby 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, so that the crayfish moves away from the transmission strip 211 until the crayfish rises to the upper end of the transmission plate 23, at which time the crayfish head faces the body 1 and is in a horizontal state, and The transmission belt 231 continues to transport the crayfish toward the body 1; when the crayfish is located at the upper end of the transmission plate 23, the gravity of the crayfish no longer pushes the rubber belt 241, so that the two ends of the rubber belt 241 are reset under the pull of the restoring force of the connecting spring 243, so that the rubber belt 241 located between the two pushing plates 24 pushes the crayfish, so that the crayfish is pushed and slides on the transmission belt 231 until the rubber belt 241 is reset and the crayfish stops sliding; the transmission belt 231 continues to transport the crayfish toward the body 1;

[0045] Because in the initial state, the storage groove 121 at the upper end of the cutting plate 12 is directly opposite to the transmission plate 23, so that the transmission belt 231 transports the crayfish through the end of the transmission plate 23 close to the body 1 and drops it into the storage groove 121 at the upper end of the cutting plate 12, and the crayfish that falls into the storage groove 121 slides along the storage groove 121 under the action of inertia until the shrimp head contacts the body 1. At this time, the shrimp head of the crayfish just crosses the cutting groove 122, and the hydraulic push rod 131 is controlled to operate so that the hydraulic push rod 131 can push the tool 13 to descend, so that the descending tool 13 cuts the crayfish in the storage groove 121 until the tool 13 is inserted into the cutting groove 122, and the shrimp head and shrimp tail of the crayfish are cut and separated by the tool 13. At this time, the crayfish tail is peeled, and then the hydraulic push rod 131 is controlled to rise so that the hydraulic push rod 131 pulls the tool 13 to reset, and then the transmission electric The machine 111 is running, so that the conveying motor 111 drives the conveyor belt 11 on the upper end of the machine head to move, so that 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 flips downward, so that the crayfish in the storage groove 121 of the cutting plate 12 falls downward under the action of its own gravity. Since the shrimp heads and shrimp tails of the crayfish are separated, two collecting boxes are placed on this side of the machine body 1, so that the shrimp heads and shrimp tails that fall downward can be collected separately, and there is no need for the operator to collect the shrimp heads and shrimp tails of the separated crayfish, which not only reduces the labor intensity of the operator, but also improves the collection efficiency of the crayfish, thereby not delaying the work of peeling the shrimp tails of the crayfish, improving the efficiency of peeling the shrimp tails of the crayfish, and further improving the practical application effect of the present invention.

[0046] As an embodiment of the present invention, a guide plate 14 is provided on the side of the transmission plate 23 close to the body 1; the guide plate 14 is rotatably connected to the conveyor frame 2; the guide plate 14 is in sliding contact with the transmission belt 231; the guide plate 14 is arranged at an angle; 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 body 1 through a torsion spring; a magnet 141 is inlaid on one side of the guide plate 14 close to the baffle 15; an electromagnetic sheet 151 is inlaid on one side of the baffle 15 close to the guide plate 14.

[0047] As an embodiment of the present invention, a slide plate 16 is slidingly and sealably connected in the storage slot 121 of the cutting board 12; the slide plate 16 is connected to one end of the cutting board 12 close to the conveying frame 2 through a support spring 161; and an electromagnetic plate 162 is embedded in one end of the cutting board 12 close to the conveying frame 2.

[0048] As an embodiment of the present invention, a partition plate 17 is arranged 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 arranged 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.

[0049] As an embodiment of the present invention, the blocking rod 171 is made of PTFE material; a cylindrical groove 172 is formed at the lower end of the blocking rod 171;

[0050] During operation, when the crayfish is transported to the guide plate 14 via the transmission plate 23, the crayfish slides down along the inclined guide plate 14. Since in the initial state, the storage groove 121 at the upper end of the cutting plate 12 is directly opposite to the end of the guide plate 14 away from the transmission plate 23, the crayfish sliding down along the inclined guide plate 14 can stably fall into the storage groove 121 at the upper end of the cutting plate 12, so that the guide plate 14 plays a guiding role between the cutting plate 12 and the transmission plate 23 to ensure that the crayfish can stably fall into the storage groove 121 of the cutting plate 12; when the transmission belt 231 drives the push plate 24 to the guide plate 14, a gap is set between the transmission belt 231 and the guide plate 14, and the width of the gap is smaller than the crayfish. The width of the lobster makes the push plate 24 move with the transmission belt 231 into the gap between the guide plate 14 and the transmission belt 231. As the push plate 24 continues to rotate downward, the push plate 24 contacts the guide plate 14. Since the lower end surface of the guide plate 14 has a rounded corner, the push plate 24 contacts the rounded corner, so that the push plate 24 pushes 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, so that the push plate 24 slides and contacts with the lower end surface of the guide plate 14, so that the push plate 24 can pass 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 the action of its own gravity, so that the guide plate 14 contacts the transmission belt 231 again. 31 side, so that the transmission belt 231 can continue to transport the crayfish to the guide plate 14, and 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 tightly attached to the guide plate 14 under the action of the adsorption force of the magnet 141, and as the user controls the electromagnetic sheet 151 to be energized, the electromagnetic sheet 151 generates a magnetic repulsion force on the magnet 141, so that the baffle 15 overcomes the torsion of the torsion spring and rotates downward under the push of the magnetic repulsion force of the magnet 141, so that the baffle 15 no longer blocks the guide plate 14, so that the crayfish in the guide plate 14 passes over the baffle 15 under the action of its own gravity and falls into the cutting plate 12; at this time, the electromagnetic sheet 15 is controlled to be energized, so that the electromagnetic sheet 151 generates a magnetic repulsion force on the magnet 141, so that the baffle 15 overcomes the torsion of the torsion spring and rotates downward, so that the baffle 15 no longer blocks the guide plate 14, and the crayfish in the guide plate 14 passes over the baffle 15 under the action of its own gravity and falls into the cutting plate 12; 1 is powered off, so that the baffle 15 is turned upward under the action of the torsion spring restoring force, until the baffle 15 is close to the magnet 141, the magnet 141 attracts the baffle 15 and quickly rotates upward until the baffle 15 is in close contact with the guide plate 14, so that the baffle 15 blocks the crayfish subsequently transported to the guide plate 14, and prevents the crayfish transported to the guide plate 14 from falling into the storage groove 121 again when the cutter 13 cuts the crayfish heads in the storage groove 121 of the cutting plate 12, resulting in the crayfish falling into the cutting plate 12 in the process of cutting the crayfish heads. The head cutting cannot be effectively performed, so as to ensure the effect of the subsequent crayfish head cutting, so that the practical application effect of the present invention is further improved;

[0051] In the initial state, the slide plate 16 is attracted by the electromagnetic plate 162 and squeezes the support spring 161 to move toward the end of the cutting plate 12 close to the conveying frame 2 until the cutting plate 12 is located below the guide plate 14. After the crayfish falls into the storage groove 121 of the cutting plate 12, the electromagnetic plate 162 is controlled to be powered off, so that the slide plate 16 moves away from the conveying frame 2 under the push of the restoring force of the support spring 161, so that the slide plate 16 pushes the crayfish that has fallen into the storage groove 121 to move toward the cutting groove 122 until the crayfish head passes over the cutting groove 122 and contacts the body 1, thereby preventing the crayfish that falls on the guide plate 14 from being unable to effectively slide and pass over the cutting groove 122 due to insufficient inertia, so as to ensure that the crayfish head can effectively pass over the cutting groove 122, and then ensure that the crayfish head can be completely cut, so as to improve the effect of removing the head and tail of the crayfish, so that the practical application effect of the present invention is effectively improved;

[0052] When the crayfish is dumped onto the conveying rack 2, the crayfish will fall on the transmission bar 211. If the curled-up crayfish lies on the transmission bar 211 with its head facing downward, the crayfish will not be able to effectively fall between the two adjacent transmission bars 211. In this regard, a blocking rod 171 is provided so that when the transmission bar 211 drives the crayfish lying on it to the blocking rod 171, the blocking rod 171 can block the crayfish, so that the crayfish is deflected under the action of the blocking force, so that the center of gravity of the deflected crayfish is shifted, so that the crayfish on the transmission bar 211 slides along the curved end of the transmission bar 211 to between the two adjacent transmission bars 211, thereby ensuring that the two adjacent transmission bars 211 can clamp and convey the crayfish with its head facing downward, so that the practicality of the present invention is effectively improved; 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, its purpose is to The purpose is to reduce the friction between the blocking rod 171 and the crayfish. When the crayfish's head passes through the two blocking rods 171, the crayfish's head contacts the blocking rod 171. At this time, the blocking rod 171 rotates under the action of the blocking force, that is, the crayfish's head pushes the blocking rod 171 to rotate through the blocking force, so that the two blocking rods 171 rotating in the direction of approaching each other can produce a pushing effect on the shrimp head, thereby accelerating the shrimp head to pass between the two blocking rods 171 to avoid the shrimp head being stuck between the two blocking rods 171. A cylindrical groove 172 is provided at the lower end of the blocking rod 171. On the one hand, the production cost of the blocking rod 171 is reduced, and on the other hand, the gravity of the blocking rod 171 is reduced to improve the effect of the crayfish's head pushing the blocking rod 171 to rotate through the blocking force, so that the pushing effect of the two rotating blocking rods 171 on the shrimp head is improved; the practical application effect of the present invention is effectively improved.
