Description

Technical Field

[0001] The present invention relates to the technical field of lobster tail processing, and particularly relates to a cleaning device for processing frozen lobster tails. Background Art

[0002] Frozen lobster tails are lobster products processed by low-temperature quick-freezing technology, mainly used as high-grade aquatic products for food processing or direct consumption. In the processing of frozen lobster tails, the cleaning link is one of the key steps, which directly affects the hygienic quality of the product and the quality of subsequent processing. The traditional processing process usually includes the following steps: First, screen live crayfish and remove unqualified individuals; then convey the crayfish into a water tank, and clean the crayfish through the bubbles and water flow generated by a bubble generator. If the crayfish are not cleaned thoroughly, they need to be cleaned repeatedly; then steam the crayfish with high-temperature steam; then manually remove the lobster tails; finally, quick-freeze the lobster tails through low-temperature treatment.

[0003] However, in the process of cleaning crayfish by the existing device, the conveying mechanism conveys the crayfish into the water tank in batches, and the number of crayfish in different batches is different. If the number of crayfish in a single batch is too large, the crayfish will accumulate and agglomerate. When the agglomerated crayfish enter the water tank for cleaning, the bubbles generated by the bubble generator can only clean the scattered crayfish without damaging the integrity of the crayfish. It is difficult for the bubbles generated by the bubble generator to disperse the agglomerated crayfish. The agglomerated crayfish will form a tight structure, making the individuals inside the crayfish group unable to contact enough bubbles and water flow, resulting in incomplete cleaning, difficult removal of residual impurities, and the need for secondary cleaning of the crayfish, increasing energy waste and reducing the processing efficiency of the crayfish. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0044] The following combines the attached Figure 1 - attached Figure 9, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

[0045] Embodiment 1: When the existing crayfish cleaning device cleans crayfish, the bubble generator impacts the crayfish with bubbles. The crayfish may be stimulated and gather into groups. The crayfish gathered into groups will form a tight structure, making the individuals inside the crayfish group unable to contact enough bubbles and water flow, resulting in incomplete cleaning, affecting the processing quality of subsequent steaming and quick-freezing, and reducing the hygiene standard of the final product.

[0046] A cleaning device for processing frozen crayfish tails, please refer to the attached Figure 1 - attached Figure 7 As shown in the figure, it includes: a cleaning tank 1, on which several filtering units are arranged, a conveyor belt and a bubble generator are arranged inside the cleaning tank 1. The filtering unit is used to separate the crayfish grouped in water. The filtering unit includes: two electric push rods 2, both fixedly connected to the cleaning tank 1. The telescopic ends of the electric push rods 2 are fixedly connected with a connecting frame 3. The connecting frame 3 is rotatably connected with a support plate 4. A first bracket 5 and a second bracket 6 are slidably connected to the support plate 4. A plurality of first round rollers 7 are rotatably connected between the two first brackets 5. A plurality of second round rollers 8 are rotatably connected between the two second brackets 6. The plurality of first round rollers 7 and the plurality of second round rollers 8 are arranged in an alternating manner; two limiting mechanisms are respectively arranged on the corresponding first brackets 5 to limit the relative moving distance between the first bracket 5 and the adjacent second bracket 6; two reciprocating mechanisms are both arranged on the cleaning tank 1 to make the first round rollers 7 and the second round rollers 8 perform continuous alternating movements. The distance between the first round roller 7 and the adjacent second round roller 8 is less than the relative moving distance between the first bracket 5 and the adjacent second bracket 6. The limiting mechanism includes: a fixed frame 21, fixedly connected to the first bracket 5, the fixed frame 21 is slidably connected to the support plate 4, and a first tension spring is fixedly connected between the fixed frame 21 and the support plate 4; a limiting frame 22, fixedly connected to the second bracket 6, the limiting frame 22 is slidably connected to the support plate 4, and a second tension spring is fixedly connected between the limiting frame 22 and the support plate 4. The limiting mechanism further includes: a fixed block 31, fixedly connected to the connecting frame 3, the fixed block 31 is used to limit the maximum included angle between the connecting frame 3 and the support plate 4; a limiting block 32, fixedly connected inside the cleaning tank 1, the limiting block 32 is used to limit one side of the support plate 4 to make the support plate 4 in an inclined state inside the cleaning tank 1. The included angle between the fixed block 31 and the connecting frame 3 is 90°, so that the plurality of first round rollers 7 and the plurality of second round rollers 8 are horizontally distributed after filtering out the grouped crayfish.

[0047] In the above solution, it aims to solve the problem that when the existing cleaning device uses bubbles to clean crayfish, it cannot handle the crayfish that gather in groups, resulting in incomplete cleaning of the crayfish. A control box is provided on the cleaning box 1, and a conveying mechanism (used to convey crayfish in batches, not shown in the figure) is provided on the right side of the cleaning box 1. Filter holes are provided on the conveyor belt in the cleaning box 1 for conveying and filtering out crayfish from the water in the cleaning box 1. The bubble generator is located at the bottom of the cleaning box 1 to impact and clean the crayfish in the water through bubbles. The conveyor belt, bubble generator, electric push rod 2, and reciprocating mechanism are all electrically connected to the control box. The crayfish entering the cleaning box 1 are conveyed from right to left by the conveyor belt inside it. Initially, the included angle between the connecting frame 3 and the support plate 4 is 90 degrees, and the support plate 4, the first round roller 7, and the second round roller 8 are located on the same horizontal plane. The operator can set the number of filtering units according to the length of the cleaning box 1. The number of filtering units in this device is two. The surfaces of the first round roller 7 and the second round roller 8 are made of rubber material (to avoid hard extrusion of the crayfish). When the electric push rod 2 contracts, the connecting frame 3 drives the support plate 4 to move downward until the left side of the support plate 4 contacts the limit block 32, forcing the support plate 4 to swing clockwise (viewed from front to back) to form an inclined state. The first round roller 7 and the second round roller 8 at the support plate 4 jointly filter the crayfish in the water, screening out the crayfish that gather in groups. The limit block 32 supports and obstructs the support plate 4 to make the multiple first round rollers 7 and multiple second round rollers 8 as a whole inclined from top to bottom to the right. The distance between the first round roller 7 and the second round roller 8 is greater than the size of a single crayfish. After the relative movement of the first round roller 7 and the second round roller 8, the gap between the first round roller 7 and the second round roller 8 can make a single crayfish fall back into the water again.

[0048] Workflow: During the processing of frozen lobster tails, when using this device to clean crayfish, the operator first fills the cleaning box 1 with water and conducts water circulation. Subsequently, the operator starts the conveyor belt and the bubble generator through the control box, and at the same time, the control panel starts all the electric push rods 2. Taking the two electric push rods 2 on the right side as an example, the telescopic ends of the two electric push rods 2 contract. The telescopic ends of the electric push rods 2 drive the two connecting frames 3 and the two support plates 4 to move downward. The two support plates 4 drive the first round roller 7 and the second round roller 8 to gradually immerse into the water in the cleaning box 1. Subsequently, the limit block 32 contacts and obstructs the left movement of the support plate 4, and the support plate 4 swings clockwise (viewed from front to back) relative to the connecting frame 3. When the telescopic ends of the electric push rods 2 are fully contracted, the control panel turns off the two electric push rods 2, and the support plate 4, the first round roller 7, and the second round roller 8 are in an inclined state in the water. After that, the control panel starts the conveying mechanism, and the screened crayfish are conveyed into the right part of the cleaning box 1 in batches by the conveying mechanism. The crayfish enter the water in the cleaning box 1, and the crayfish are impacted by bubbles in the water to achieve the cleaning effect. At the same time, the crayfish are gradually conveyed to the left by the conveyor belt working in the cleaning box 1 and filtered out of the water. The filtered crayfish enter the subsequent steaming stage.

[0049] In the process of crayfish entering the cleaning box 1 in batches, if the number of crayfish in a batch is too large, the crayfish will clump together. After the crayfish in this batch enters the water in the cleaning box 1, the crayfish that are clumped together will not be completely dispersed under the impact of bubbles. When the crayfish pass through the gap between the first round roller 7 and the second round roller 8, the crayfish that are not clumped together can pass smoothly, while the crayfish that are clumped together are blocked and cannot continue to move to the left. Subsequently, the two filtering units work alternately, and the control panel first starts the filtering unit on the right. Taking the filtering unit on the right as an example, the control panel starts the two electric push rods 2 on the right. The telescopic ends of the electric push rods 2 extend out and drive the support plate 4 to move upward through the connecting frame 3. The first round roller 7 and the second round roller 8 move synchronously with the support plate 4, and the crayfish that are clumped together are screened out of the water by the first round roller 7 and the second round roller 8. During the movement, the support plate 4 gradually swings downward and resets under the action of gravity of the first round roller 7 and the second round roller 8 connected thereto. When the support plate 4 loses contact with the limit block 32, the support plate 4 leaves the water surface and returns to its initial position. The connecting frame 3 limits the support plate 4 through the fixed block 31, and the support plate 4 returns to a horizontal state. Then the control panel starts the reciprocating mechanism, which first moves the fixing frame 21 and the limit frame 22 away from each other, the fixing frame 21 stretches the first tension spring connected thereto, and the limit frame 22 stretches the second tension spring connected thereto, and then the fixing frame 21 moves and resets under the tension of the first tension spring connected thereto, and the limit frame 22 moves and resets under the tension of the second tension spring connected thereto, and then the reciprocating mechanism pushes the fixing frame 21 and the limit frame 22 away from each other again, and the fixing frame 21 and the limit frame 22 cause the first bracket 5 and the second bracket 6 to perform continuous reciprocating movement.

[0050] During the continuous reciprocating movement of the first bracket 5 and the second bracket 6, the first bracket 5 and the second bracket 6 control all the first round rollers 7 and all the second round rollers 8 to move alternately, and the first round rollers 7 and the second round rollers 8 flexibly squeeze the crayfish clusters thereon by alternating movement (simulating the undulating state of waves), so that the crayfish clusters are gradually dispersed under the action of flexible squeezing, and the dispersed crayfish fall back into the water in the cleaning tank 1 from the gap between the first round rollers 7 and the second round rollers 8. After the reciprocating mechanism works for a period of time (the operator sets the duration of the alternating movement of the first round rollers 7 and the second round rollers 8 in advance to smoothly separate the crayfish clusters), the control panel turns off the reciprocating mechanism, and at the same time the control box controls the two electric push rods 2 to make the first The round roller 7 and the second round roller 8 are immersed in water again to screen the crayfish, and then the filtering unit on the left is started to repeat the above-mentioned operation of screening the crayfish into groups and dispersing the crayfish groups. The two groups of filtering units work alternately to continuously screen and disperse the gathered crayfish groups, thereby ensuring the comprehensiveness of the crayfish cleaning by the device and improving the sanitary quality of the final product. When all the crayfish in the cleaning box 1 are cleaned, the control box controls the telescopic ends of all the electric push rods 2 to extend, so that all the support plates 4 return to their initial positions. At this point, all parts in the device are reset, and the control panel turns off the conveying mechanism, conveyor belt and bubble generator. Then, the operator drains all the water in the cleaning box 1, and finally the operator can clean the device.

[0051] Please refer to the attached Figure 3 , Attachment Figure 4 and attached Figure 7 As shown, the reciprocating mechanism includes: a motor 41, which is fixed to the cleaning box 1, and the output shaft of the motor 41 is fixedly connected to a rotating plate 42, and the rotating plate 42 is slidably connected to a transmission frame 43, and a spring is fixedly connected between the rotating plate 42 and the transmission frame 43, and the transmission frame 43 is used to squeeze the fixed frame 21 and the limit frame 22; a transmission component, which is arranged on the cleaning box 1, and is used to control the transmission frame 43 to be inserted between the fixed frame 21 and the limit frame 22, and the transmission component includes: a sliding frame 51, which is slidably connected to the cleaning box 1, and a third tension spring is fixedly connected between the sliding frame 51 and the cleaning box 1, and the sliding frame 51 is used to squeeze the adjacent support plate 4; a fixed plate 52, which is fixed to the sliding frame 51, and the fixed plate 52 is used to push the transmission frame 43 to move relative to the rotating plate 42.

[0052] In the above solution, it is aimed to actively control the alternating movement of the first bracket 5 and the second bracket 6 above the water surface without interfering with the operation of the support plate 4 being immersed in the water to filter the crayfish mass through the first roller 7 and the second roller 8. Taking the transmission frame 43 on the right front as an example, the transmission frame 43 is composed of a circular ring and two cylinders. The distances between the two cylinders on the transmission frame 43 and the rotation axis of the rotating plate 42 are the same. The fixed plate 52 is composed of a U-shaped plate at the upper part, an inclined plate in the middle, and a vertical plate at the lower part. Initially, the rear side of the vertical plate of the fixed plate 52 is in contact with the transmission frame 43. The lengths of the two cylinders on the transmission frame 43 extending beyond the rear side of the rotating plate 42 are equal to the distance between the rear sides of the U-shaped plate and the vertical plate on the fixed plate 52, and the plane where the rear side of the rotating plate 42 is located is flush with the plane where the front side of the support plate 4 is located. Initially, the third tension spring connected to the sliding frame 51 is in a stretched state, and the spring connected to the transmission frame 43 is in a compressed state.

[0053] Workflow: When the control box controls the telescopic end of the electric push rod 2 to contract, the telescopic end of the electric push rod 2 drives the support plate 4 to move downward through the connecting frame 3. Taking the sliding frame 51 on the right front side as an example, the sliding frame 51 moves downward under the pulling force of the third tension spring connected to it, and the fixed plate 52 releases the extrusion on the transmission frame 43. The transmission frame 43 moves forward under the elastic force of the spring connected to it. The two cylinders on the transmission frame 43 lose contact with the fixed frame 21 and the limit frame 22. Then, when the control box controls the electric push rod 2 to drive the support plate 4 to move upward and reset through the connecting frame 3, the support plate 4 contacts and pushes the sliding frame 51 to move upward. The sliding frame 51 stretches the third tension spring connected to it. The sliding frame 51 squeezes the transmission frame 43 to move backward through the fixed plate 52. The transmission frame 43 compresses the spring connected to it. The two cylinders on the transmission frame 43 are inserted between the fixed frame 21 and the limit frame 22 through the rotating plate 42. At the same time, the support plate 4 returns to its initial position. Subsequently, the control panel starts the motor 41, and the motor 41 drives the rotating plate 42 to rotate. The transmission frame 43 rotates synchronously with the rotating plate 42. The cylindrical structures on both sides of it periodically squeeze the fixed frame 21 and the limit frame 22, forcing the first bracket 5 and the second bracket 6 to reciprocate relative to the support plate 4, thereby realizing the alternating movement of the first roller 7 and the second roller 8. When the motor 41 has been started for a period of time (that is, when the working time of the motor 41 reaches the duration of the alternating movement of the first roller 7 and the second roller 8 set in advance by the operator), the control panel turns off the motor 41 and repeats the above operations until all the crayfish are cleaned by this device.

[0054] Example 2: On the basis of Example 1, please refer to Appendix Figure 1 Appendix Figure 2 Appendix Figure 8 Appendix Figure 9As shown in the figure, it further includes: auxiliary mechanisms, the number of which is the same as that of the filtering units, and are all arranged on the cleaning tank 1, and are used for assisting in extruding the crayfish when the first round roller 7 and the second round roller 8 move alternately to disperse the agglomerated crayfish. The auxiliary mechanism includes: a fixed frame 61, fixedly connected to the cleaning tank 1, a flexible plate 62 is arranged inside the fixed frame 61, and the flexible plate 62 covers above all the first round rollers 7 and all the second round rollers 8 in the corresponding filtering unit; a tension control component, arranged on the flexible plate 62, and is used for pre-adjusting the tension degree of the flexible plate 62. The flexible plate 62 is a flexible metal plate with a plurality of through holes. The tension control component includes: a plurality of pull ropes 71, respectively fixedly connected to both sides of the flexible plate 62, and a fastening bolt 72 is fixedly connected to the pull rope 71, and the fastening bolt 72 is threadedly connected to the fixed frame 61.

[0055] In the above solution, it aims to solve the problem that during the process of screening crayfish in water, it is impossible to accurately judge whether the crayfish groups on the first round roller 7 and the second round roller 8 are dispersed, and the situation where the first round roller 7 and the second round roller 8 drive the crayfish groups to re-enter the water will occur; an intelligent monitoring device (an existing device, not shown in the figure) is arranged on the fixed frame 61, and is used for monitoring whether there are remaining crayfish on the first round roller 7 and the second round roller 8 through the through holes on the flexible plate 62. The intelligent monitoring device is electrically connected to the control box.

[0056] Working process: Before starting this device, the operator first rotates all the fastening bolts 72 according to the hardness of the outer shells of the crayfish to be cleaned. The fastening bolts 72 stretch the flexible plate 62 through the pull ropes 71 to change the tension of the flexible plate 62 (if the shell of the crayfish is harder, the greater the force of the pull rope 71 stretching the flexible plate 62, the greater the tension of the flexible plate 62). After the telescopic end of the electric push rod 2 drives the support plate 4 to return to the initial position through the connecting frame 3, if the intelligent monitoring device monitors that there are crayfish on the first round roller 7 and the second round roller 8, the control panel starts the motor 41. The output shaft of the motor 41 makes the first round roller 7 and the second round roller 8 move alternately through the rotating plate 42 and the transmission frame 43. The flexible plate 62 provides a small amount of extrusion for the crayfish group. The first round roller 7 and the second round roller 8 cooperate with the flexible plate 62 to disperse the crayfish group by continuous flexible extrusion and dislocation, ensuring that the crayfish in the water in the cleaning tank 1 are comprehensively cleaned by the bubbles, and improving the cleanliness of the crayfish after being cleaned by this device. During the process of the first round roller 7 and the second round roller 8 moving alternately to squeeze the crayfish group, if the intelligent monitoring device monitors that all the crayfish on the first round roller 7 and the second round roller 8 are dispersed and fall into the water, the control panel controls the electric push rod 2 to make the first round roller 7 and the second round roller 8 re-enter the water to screen the crayfish group. When this device finishes cleaning all the crayfish, the operator rotates the fastening bolts 72 to make the flexible plate 62 return to the relaxed state.
