[0053] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, unless otherwise clearly specified and defined, the terms "installed", "connected", and "joined" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] As Figure 1 shown, the present invention provides a metering and feeding device. The metering and feeding device 10 includes a conveying table 11, a feeding conveying mechanism 12, a supporting upright frame 14, a receiving and metering mechanism 15, a turntable feeding mechanism 16, a brush 17, and a controller 13. Among them, the controller 13 is arranged at the side end of the conveying table 11, and the conveying speeds of the conveying table 11, the feeding conveying mechanism 12, the receiving and metering mechanism 15, and the turntable feeding mechanism 16 are all controlled by the controller 13, so as to realize intelligent automatic uniform and constant-speed conveying in the whole conveying process.

[0055] Specifically, the feeding conveying mechanism 12 is arranged at the front end of the conveying table 11, the supporting upright frame 14 is erected above the feeding end of the conveying table 11, the receiving and metering mechanism 15 is arranged on the supporting upright frame 14, the receiving and metering mechanism 15 is used to receive the materials conveyed by the feeding conveying mechanism 12 and measure the weight of the materials, the turntable feeding mechanism 16 is arranged on the supporting upright frame 14, the turntable feeding mechanism 16 is used to take out the materials in the receiving and metering mechanism 15, and the brush 17 is arranged on the supporting upright frame 14, and the brush 17 is used to dial the materials on the turntable feeding mechanism 16 onto the conveying table 11. First, the present invention uses the feeding conveying mechanism 12 to convey materials (such as shrimp bodies) to the receiving and metering mechanism 15, realizing automatic weighing of the materials during the conveying process, which is beneficial to subsequent classification and processing. The metered materials are then taken out by the turntable feeding mechanism 16, and the materials on the turntable feeding mechanism 16 are dialed onto the conveying table 11 through the brush 17, so that the materials can be conveyed on the conveying table 11 in a roughly uniform and separated manner, avoiding the phenomena of material stacking and overlapping, and effectively improving the production efficiency and quality. Second, the controller 13 is used to control the conveying speeds of the conveying table 11, the feeding conveying mechanism 12, the receiving and metering mechanism 15, and the turntable feeding mechanism 16, so as to control the conveying interval of the materials.

[0056] In some examples of the present invention, please refer to Figure 2, The material receiving and metering mechanism 15 includes a material receiving jitter component 151 and a metering component 152. The metering component 152 is installed on the support vertical frame 14, and the metering component 152 is connected to the material receiving jitter component 151. Among them, the material receiving jitter component 151 is used to receive the materials conveyed by the feeding conveyor mechanism 12, and the metering component 152 is used to measure the weight of the materials falling into the material receiving jitter component 151 in real time and feed the real-time measurement data back to the controller 13. The controller 13 adjusts and controls the conveying speeds of the conveying table 11, the feeding conveyor mechanism 12, the material receiving and metering mechanism 15, and the turntable feeding mechanism 16 according to the data fed back by the metering component 152 to ensure the stable and intermittent conveying of the materials.

[0057] To ensure the metering accuracy of the metering component 152, two sets of metering components 152 are provided and are respectively arranged on the outer walls at opposite ends of the material receiving groove 1511. Preferably, the two sets of metering components 152 are arranged axially symmetrically on the material receiving groove 1511.

[0058] Further, please continue to refer to Figure 2 , The material receiving jitter component 151 includes a material receiving groove 1511. The material receiving groove 1511 is arranged at the discharge end of the feeding conveyor mechanism 12. Preferably, the material receiving groove 1511 is of a funnel structure, and its opening is tapered from top to bottom so that the materials can fall to the bottom of the material receiving groove 1511.

[0059] To prevent the materials from adhering to the inner wall of the material receiving groove 1511, a vibration motor 1512 is arranged on the outer wall of the material receiving groove 1511, which further ensures that the materials can fall to the bottom of the material receiving groove 1511 and be smoothly taken out by the turntable feeding mechanism 16, ensuring the processing efficiency.

[0060] In some examples of the present invention, as Figure 2 shown, the metering component 152 includes a first fixing plate 1521 connected to the support vertical frame 14, a weight sensor 1522 fixed on the first fixing plate 1521, and an elastic module. The elastic module is used to connect the material receiving groove 1511 and the support plate 1523. To ensure the metering accuracy, a support plate 1523 needs to be arranged directly above the weight sensor 1522 so that the materials and the material receiving groove 1511 can completely and positively press on the weight sensor 1522, thereby improving the metering accuracy and facilitating subsequent classification processing. The elastic module cooperates with the vibration motor 1512 to vibrate the material receiving groove 1511 so that the materials slide evenly to the bottom of the funnel.

[0061] Please continue to combine with Figure 2, the elastic module includes a spring piece 1524 connected to the support plate 1523 and a connecting piece 1525 installed on the side wall of the material receiving groove 1511. The spring piece 1524 is connected to the connecting piece 1525, and the spring piece 1524 is used to cooperate with the vibration motor 1512 to further ensure that the material can slide to the bottom of the funnel. Among them, the vibration motor 1512 and the weight sensor 1522 work alternately. When the vibration motor 1512 works, the weight sensor 1522 stops detecting. Since only the material in the material receiving groove 1511 is vibrated and dropped to the bottom, the working time of the vibration motor 1512 is generally 1-2 seconds. When the vibration motor 1512 stops working, the weight sensor 1522 measures the weight in real time. During the real-time measurement process, if the detected data deviates from the set value, the controller 13 adjusts and controls the conveying speeds of the conveying table 11, the feeding conveying mechanism 12, the material receiving and metering mechanism 15, and the turntable feeding mechanism 16 according to the data fed back by the weight sensor 1522 to ensure the continuous and stable conveying of the material.

[0062] In some examples of the present invention, please refer to Figure 3 , the turntable feeding mechanism 16 includes a turntable feeding component 161 and a driving component 162. The driving component 162 is arranged on the support vertical frame 14; specifically, the turntable feeding component 161 includes a turntable body 1611 and a connecting disk 1612 arranged coaxially. The connecting disk 1612 is controlled by the driving component 162. Among them, at least a part of the turntable feeding component 161 extends into the material receiving groove 1511. Specifically, a part of the turntable body 1611 extends into the inner side of the material receiving groove 1511 to facilitate taking out the material from the material receiving groove 1511. For this reason, an avoidance groove 1514 needs to be opened on one side of the material receiving groove 1511 close to the turntable feeding mechanism 16, and the turntable body 1611 extends into the material receiving groove 1511 through the avoidance groove 1514.

[0063] To further ensure that the turntable body 1611 can take out the material in the material receiving groove 1511, a plurality of feeding needle assemblies 1613 are provided on the end face of the turntable body 1611, preferably 3 groups. Since the material receiving groove 1511 is a funnel structure, in order to prevent the material from falling from the bottom of the material receiving groove 1511, the bottom opening is set smaller, and the feeding needle assemblies 1613 will rotate with the turntable body 1611 into the interior of the material receiving groove 1511. In order to avoid action interference between the feeding needle assemblies 1613 and the material receiving groove 1511, an avoidance hole 1513 is opened at the bottom of the material receiving groove 1511 to ensure that the feeding needle assemblies 1613 can smoothly enter the material receiving groove 1511 to pick up the material.

[0064] Specifically, taking three groups of loading needle assemblies 1613 as an example, to avoid mutual interference and achieve evenly spaced material picking, the distances of each group of loading needle assemblies 1613 from the center of the turntable body 1611 are all different. For example, the distance between the first group of loading needle assemblies 1613 and the center of the turntable body 1611 is set as L1, the distance between the second group of loading needle assemblies 1613 and the center of the turntable body 1611 is set as L2, and the distance between the third group of loading needle assemblies 1613 and the center of the turntable body 1611 is set as L3. Then L1 < L2 < L3, or L3 < L2 < L1, and the number of avoidance holes 1513 is the same as the number of groups of loading needle assemblies 1613, that is, three.

[0065] In a specific example of the present invention, L1, L2, and L3 are not on the straight line where the same diameter is located. The included angles between L1 and L2 and the center of the circle, and between L2 and L3 and the center of the circle are preferably 60°.

[0066] Furthermore, each group of loading needle assemblies 1613 has two, and the two loading needle assemblies 1613 are respectively arranged on the two end faces of the turntable body 1611. Each group of loading needle assemblies 1613 is placed at the relative positions on the same diameter of the turntable body 1611, that is, one group of loading needle assemblies 1613 is arranged on the front and back faces of the turntable body 1611, which can ensure that the loading needle assemblies 1613 pick up the materials falling on the two end faces of the turntable body 1611. And one group of loading needle assemblies 1613 is relatively arranged about the center of the circle on the same diameter, and the distances from the two to the center of the turntable body 1611 are equal. This setting makes the loading needle assemblies 1613 evenly arranged on the end face of the turntable body 1611. Taking three groups of loading needle assemblies 1613 as an example, there are six loading needle assemblies 1613 at this time. Thus, every time the turntable body 1611 rotates 60°, one loading needle assembly 1613 enters the material receiving groove 1511 through the avoidance hole 1513, so as to achieve the purpose of evenly spaced conveying.

[0067] In some examples of the present invention, please refer to Figure 4 , the loading needle assembly 1613 includes a fixing member 16131 installed on the turntable body 1611. A clamping groove 16132 is formed on the fixing member 16131, and a loading thorn needle 16133 is clamped on the clamping groove 16132. Among them, the loading thorn needle 16133 is used for puncturing the material and taking it out of the material receiving groove 1511. Therefore, the orientation of the loading thorn needle 16133 is the same as the rotation direction of the turntable body 1611.

[0068] Specifically, taking Figure 3For example, the end face of the turntable body 1611 provided with the driving assembly 162 is set as the front face. When the turntable body 1611 rotates clockwise, the feeding needle assembly 1613 enters the receiving groove 1511 from the avoidance hole 1513 at the bottom of the receiving groove 1511. At this time, the feeding thorn needle 16133 is arranged upward. During the rotation of the turntable body 1611, the feeding thorn needle 16133 punctures the material and brings the material out from the top opening of the receiving groove 1511. When the material comes to one side of the brush 17 along with the turntable body 1611, at this time, the feeding thorn needle 16133 gradually faces downward, and under the action of the brush 17, the material punctured by the feeding thorn needle 16133 is dialed onto the conveying table 11, so that the material can be conveyed on the conveying table 11 in a roughly uniform separation manner, avoiding the phenomena of material stacking and overlapping, and effectively improving the production efficiency and quality.

[0069] As a preferred method, the brush 17 is driven by a separate motor (not shown), and the rotation direction of the brush 17 is opposite to the rotation direction of the turntable body 1611. At the same time, the rotation speed of the brush 17 needs to be greater than the rotation speed of the turntable body 1611 to ensure that the material punctured by the feeding thorn needle 16133 can be dialed onto the conveying table 11. In other methods, the brush 17 can also be linked with the turntable body 1611 through a gear accelerator.

[0070] In other examples of the present invention, to ensure the disassembly, assembly and replacement of the feeding thorn needle 16133, a locking bolt 16134 for adjusting the tension of the clamping groove 16132 is arranged at the position of the fixing member 16131 relative to the clamping groove 16132. The tightness of the clamping groove 16132 can be adjusted through the locking bolt 16134, so as to facilitate the disassembly and assembly of the feeding thorn needle 16133.

[0071] In some examples of the present invention, please refer to Figure 4 , the driving assembly 162 includes a second fixing plate 1621, a mounting plate 1622 and a driving shaft 1625. Among them, the second fixing plate 1621 is arranged on the supporting vertical frame 14, at least two bearing seats 1624 are arranged on the second fixing plate 1621, the mounting plate 1622 is arranged at the end of the second fixing plate 1621, a driving motor 1623 is arranged on the mounting plate 1622, the driving shaft 1625 is arranged on the bearing seats 1624, one end of the driving shaft 1625 is connected with the connecting disc 1612, and the other end is connected with the driving motor 1623 through a coupling 1626. The driving motor 1623 drives the driving shaft 1625 to rotate through the coupling 1626, and then drives the turntable body 1611 to rotate, realizing intermittent material taking and conveying.

[0072] In other examples of the present invention, such as Figure 1As shown in the figure, the loading and conveying mechanism 12 includes a loading chute 124 and a conveying assembly. The loading chute 124 is used to accommodate materials (such as shrimp bodies), and the conveying assembly is arranged between the loading chute 124 and the receiving and metering mechanism 15 for conveying the materials in the loading chute 124 to the receiving and metering mechanism 15.

[0073] In other examples of the present invention, the conveying assembly includes a hoist 121 and a blanking tray 123. The hoist 121 is inclined and its feeding end extends into the loading chute 124. The blanking tray 123 is arranged at the discharging end of the hoist 121, and the discharging end of the blanking tray 123 is connected to the receiving and metering mechanism 15. The lifting speed of the hoist 121 is controlled by the controller 13. Through the hoist 121 and the blanking tray 123, the conveying efficiency can be effectively guaranteed, and uniform material taking and conveying can be realized.

[0074] In other examples of the present invention, in order to smoothly take out the materials in the loading chute 124, a number of retaining bars 122 are arranged at intervals on the hoist 121, which can also avoid excessive materials being conveyed at one time and resulting in non-uniform conveying.

[0075] In some examples of the present invention, please refer to Figure 5 : The control logic of the controller 13 is as follows: First, detect the weight of the receiving chute 1511 and set a fixed value after the materials enter the receiving chute 1511. When the value measured by the weight sensor 1522 is less than the fixed value, the controller 13 controls the hoist 121 to speed up so that more materials can enter the receiving chute 1511, and then adjusts the rotation speeds of the turntable body 1611, the brush 17, and the conveying table 11 to match the rotation speed of the hoist 121; on the contrary, when the value measured by the weight sensor 1522 is greater than the fixed value, the hoist 121 decelerates.

[0076] The working process of the present invention is as follows: Taking the shrimp body as an example of the material, please refer to Figures 1 to 4, after placing the shrimp body in the feeding trough 124, start the conveying assembly, the material receiving and weighing mechanism 15, the rotary table feeding mechanism 16, the brush 17 and the conveying table 11. At this time, the shrimp body is conveyed to the blanking plate 123 by the elevator 121 and falls into the material receiving groove 1511 through the blanking plate 123. Under the cooperation of the vibration motor 1512 and the spring piece 1524, the shrimp body falls to the bottom of the material receiving groove 1511. At this time, the weight sensor 1522 automatically measures the weight of the shrimp body. The drive motor 1623 drives the drive shaft 1625 to rotate through the coupling 1626, and then drives the rotary table body 1611 to rotate. During the rotation of the rotary table body 1611, the feeding needle assembly 1613 enters the material receiving groove 1511 from the avoidance hole 1513 at the bottom of the material receiving groove 1511. At this time, the feeding thorn needle 16133 is arranged upward. During the rotation with the rotary table body 1611, the feeding thorn needle 16133 punctures the material and brings the material out from the top opening of the material receiving groove 1511. When the material comes to one side of the brush 17 along with the rotary table body 1611, at this time, the feeding thorn needle 16133 gradually faces downward, and the material punctured by the feeding thorn needle 16133 is dialed onto the conveying table 11 under the action of the brush 17, so that the material can be conveyed on the conveying table 11 in a roughly uniform and separated manner, thereby realizing the intelligent control of the uniform and non-overlapping transportation of shrimps at a constant speed to the next processing process.

[0077] In summary, a metering and feeding device provided by the present invention uses the feeding and conveying mechanism 12 to convey the material to the material receiving and weighing mechanism 15, realizes the automatic weighing of the material during the conveying process, which is beneficial to subsequent classification processing. The metered material is then taken out by the rotary table feeding mechanism 16, and the material on the rotary table feeding mechanism 16 is dialed onto the conveying table 11 by the brush 17, so that the material can be conveyed on the conveying table 11 in a roughly uniform and separated manner, avoiding the phenomena of material stacking and overlapping, and effectively improving the production efficiency and quality. Secondly, the controller 13 is used to control the conveying speeds of the conveying table 11, the feeding and conveying mechanism 12, the material receiving and weighing mechanism 15 and the rotary table feeding mechanism 16, so as to control the conveying interval of the material.
