[0030] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention provides an automated raw material weighing and feeding device through improvement. The technical solution of the present invention is:

[0032] like Figures 1 to 8 As shown, an embodiment of the present invention provides an automated raw material weighing and feeding device, comprising a table plate 1 and an annular groove 2 on the upper side, a plurality of slides 3 are movably arranged on the inner side of the annular groove 2, a weighing plate 4 is arranged above each slide 3, and a circulating mechanism for driving the plurality of slides 3 to circulate is arranged on the table plate 1; two inner guide pillars 5 are fixed on one side of each slide 3, sleeve rods 6 are slidably sleeved on the upper ends of the two inner guide pillars 5, a cross plate 8 is fixed on the upper sides of the two sleeve rods 6, and the lower sides of the two sleeve rods 6 are connected with induction springs 7, and a flipping mechanism is arranged between the cross plate 8 and the weighing plate 4; a driving mechanism for driving the flipping mechanism is arranged on the other side of each slide 3, and the two sleeve rods 6 are movably connected to the driving mechanism through two reversing rods 9 that rotate forward and backward; a plurality of trigger mechanisms for pushing the driving mechanism are arranged on one side of the table plate 1, and a discharging slide plate 17 is connected to the position of each trigger mechanism on one side of the table plate 1.

[0033] Furthermore, the flipping mechanism includes a rotating cylinder 101 rotatably connected to one end of the upper side of the transverse plate 8, a limit block 102 fixed to the upper side of the transverse plate 8 and a first piston cylinder 103. The rotating cylinder 101 is fixedly connected to the weighing plate 4. The inner side of the first piston cylinder 103 is slidably connected to a first piston plate 104. One end of the first piston plate 104 is fixed with a first push rod 106 extending to the inner side of the rotating cylinder 101, and the first piston plate 104 is elastically connected to the inner end of the first piston cylinder 103 through a return spring 105. The first push rod 106 penetrates and is slidably connected to the inside of the limit block 102. Two spiral grooves 108 arranged in a circle are provided on both sides of the rotating cylinder 101. One end of the first push rod 106 is fixed with two spiral grooves 108 slidably connected to the two spiral grooves. The reversing slide pin 107 on the inner side of the groove 108, the driving mechanism includes two outer guide pillars 201 fixed on one side of the slide 3, the outer sides of the two outer guide pillars 201 are slidably connected with a lifting plate 202, a second piston cylinder 203 is fixed at the middle section of the lifting plate 202, the inner side of the second piston cylinder 203 is slidably connected with a second piston plate 204, one end of the second piston plate 204 is fixed with a second push rod 205 extending to the outside of the second piston cylinder 203, the end of the second push rod 205 is rotatably connected with a drag reduction roller 206, one end of the second piston cylinder 203 is connected to the inner side of the first piston cylinder 103 through a connecting pipe 207, and one end of the inner side of the second piston cylinder 203, one end of the inner side of the first piston cylinder 103 and the inner side of the connecting pipe 207 are all filled with hydraulic oil;

[0034] After the second push rod 205 of the driving mechanism is pushed, it drives the second piston plate 204 to move. The second piston plate 204 presses the hydraulic oil at one end of the inner side of the second piston cylinder 203 into one end of the inner side of the first piston cylinder 103 of the flip mechanism through the connecting pipe 207. The hydraulic oil pushes the first piston plate 104 of the flip mechanism to move. The first piston plate 104 drives the first push rod 106 to extend and move toward the inner side of the rotating cylinder 101. At the same time, the first piston plate 104 compresses the return spring 105, and the limit block 102 can limit the rotation of the first push rod 106, so that the first push rod 106 can be rotated. The rod 106 moves horizontally along a straight line. The first push rod 106 slides with the two spiral grooves 108 through the two reversing sliding pins 107 at one end. When the first push rod 106 moves toward the inside of the rotating cylinder 101, it can drive the rotating cylinder 101 to rotate a certain angle, and the rotating cylinder 101 drives the weighing plate 4 to rotate a certain angle, so that the aquatic products carried on the upper side of the weighing plate 4 can be poured down, and the aquatic products can slide to the upper side of the discharge slide plate 17 corresponding to the trigger mechanism at this location, thereby realizing the function of automatically weight classification and feeding of aquatic products of different weights.

[0035] Furthermore, two first slots 11 are symmetrically provided at both ends of the two reversing rods 9, and a first sliding pin 12 slidably connected to the inner side of the first slot 11 is fixed to one side of the lower end of the two sleeve rods 6. Two second sliding pins 13 slidably connected to the inner side of the first slot 11 are fixed to both ends of the lifting plate 202. The two reversing rods 9 are rotatably connected to the slide table 3 through a rotating shaft 10. Through the sliding cooperation between the first sliding pin 12 and the first slot 11 and the sliding cooperation between the second sliding pin 13 and the first slot 11, the up and down movement of the two sleeve rods 6 can be converted into the reverse up and down movement of the driving mechanism, thereby amplifying the up and down movement stroke of the sleeve rod 6 and the weighing plate 4, and improving the sensitivity of weight classification.

[0036] Furthermore, the trigger mechanism includes two push plate guide rods 301 fixed to one side of the platform 1 and an adjusting screw 303 (such as Figure 6 As shown, the outer sides of the two push plate guide rods 301 are slidably connected with the trigger push plate 302, and the adjusting screw 303 is rotatably connected to the inside of the trigger push plate 302 through a thread, and one side of the trigger push plate 302 is provided with two push inclined surfaces 304 at both ends for pushing the drag reduction roller 206;

[0037] By rotating the adjusting screw 303, the height of the trigger push plate 302 can be adjusted. The trigger push plates 302 of different heights can push the drag reduction rollers 206 of the driving mechanisms of different heights, thereby accurately triggering the driving mechanism to drive the flipping mechanism to operate, thereby accurately controlling the flipping of the weighing plate 4, and tipping over the aquatic products carried on its upper side, thereby improving the accuracy of material distribution.

[0038] Furthermore, the circulation mechanism includes a traction column 401 fixed on one side of each slide 3, two pulleys 403 rotatably connected to the two ends of the upper side of the table 1, and a motor 402 installed on the lower side of the table 1, the driving end of the motor 402 is fixedly connected to one end of one of the pulleys 403, the outer sides of the two pulleys 403 are connected by a transmission belt 404, and a traction plate 405 is fixed on the outer side of the transmission belt 404 at the position corresponding to each traction column 401, and one end of each traction plate 405 is provided with a movable groove 406 movably connected to the traction column 401;

[0039] The motor 402 of the circulation mechanism can drive one of the pulleys 403 to rotate, and this pulley 403 drives the transmission belt 404 and the other pulley 403 to rotate synchronously. The transmission belt 404 applies thrust to the traction column 401 on the upper side of each slide 3 through multiple traction plates 405 on the outside, thereby driving multiple slides 3 to move in a circulation along the inner side of the annular groove 2. Each slide 3 drives the weighing plate 4 above and the single aquatic product it carries to move in a circulation along the trajectory of the annular groove 2, thereby improving the weight classification efficiency.

[0040] Furthermore, four guide rollers 15 are rotatably connected at the four corners of each slide 3, and a limiting groove 16 is provided at the edge of each guide roller 15. The inner side of the annular groove 2 is fixed with a convex strip 14 that can be matched with the inner side of the limiting groove 16 at the position of the two side walls.

[0041] The guide rollers 15 can make the slide 3 move more smoothly along the inner side of the annular groove 2, thereby preventing the slide 3 from shaking left and right, thereby improving the operating reliability of the device.

[0042] Furthermore, one end of each of the two spiral grooves 108 is smoothly provided with a straight groove 109 parallel to the axis of the rotating cylinder 101;

[0043] When the drag-reducing roller 206 of the driving mechanism is separated from the trigger mechanism, the reset spring 105 is reset, pushing the first piston plate 104 to move in the opposite direction and reset, thereby restoring the weighing disc 4 to a horizontal angle. At the same time, the first push rod 106 and the reversing slide pin 107 are synchronously reversed and reset with the first piston plate 104. When the reversing slide pin 107 slides from the inner side of the spiral groove 108 to the inner side of the straight groove 109, the angle of the rotating cylinder 101 can be locked to prevent the rotating cylinder 101 and the upper weighing disc 4 from rotating, thereby ensuring that the weighing disc 4 provides stable support for the aquatic products.

[0044] After the aquatic products carried on the upper side of the weighing plate 4 fall down, the aquatic products will slide to the upper side of the discharge slide plate 17 corresponding to the trigger mechanism at that location, thereby realizing the function of automatically classifying and feeding aquatic products of different weights.

[0045] Furthermore, the distance between the two first sliding pins 12 and the rotating shaft 10 is smaller than the distance between the two second sliding pins 13 and the rotating shaft 10;

[0046] By making the distance between the two first sliding pins 12 and the rotating shaft 10 smaller than the distance between the two second sliding pins 13 and the rotating shaft 10, when one end of the reversing rod 9 close to the first sliding pin 12 rotates downward to a smaller height, it is ensured that the other end thereof can rotate upward to a larger height, so that the upward stroke of the driving mechanism can be driven to be greater than the downward stroke of the weighing pan 4, thereby improving the sensitivity of the height change of the driving mechanism, so that the height change of the driving mechanism is more affected by aquatic products of different weights, thereby helping to improve the accuracy of the weight classification of each aquatic product and further improving the reliability of the device.

[0047] Working principle: Before use, the adjusting screw 303 of the trigger mechanism is rotated, and the adjusting screw 303 drives the trigger push plate 302 to move up and down through the thread (the multiple slides 3 close to the trigger mechanism are located on the front side, and the multiple slides 3 away from the trigger mechanism are located on the rear side), and the height of the trigger push plates 302 of the multiple trigger mechanisms is adjusted to increase in sequence along the moving direction of the multiple slides 3 on the front side;

[0048] When in use, the aquatic products to be weighed and fed are randomly placed on the upper side of the weighing plate 4 from the side relative to the discharging slide plate 17, and the motor 402 of the circulation mechanism can drive one of the pulleys 403 to rotate, and this pulley 403 drives the transmission belt 404 and the other pulley 403 to rotate synchronously, and the transmission belt 404 applies a thrust to the traction column 401 on the upper side of each slide 3 through multiple traction plates 405 on the outside, so that the multiple slides 3 can be driven to circulate along the inner side of the annular groove 2, and each slide 3 drives the upper weighing plate 4 and the single aquatic product carried by it to move from one side of the table 1 to the other side;

[0049] When the upper side of the weighing plate 4 carries aquatic products, the weighing plate 4 will transfer the weight to the two sleeve rods 6, so that the two sleeve rods 6 move down along the outer side of the inner guide column 5 and compress the two induction springs 7. When the weight of a single aquatic product is different, the two sleeve rods 6 have different descending strokes, so the compression degree of the two induction springs 7 is also different. When the two sleeve rods 6 move down, the two first sliding pins 12 and the two first slots 11 can drive the two reversing rods 9 to rotate synchronously. The two reversing rods 9 can drive the lifting plate 202 of the driving mechanism to move upward along the outer guide column 201 through the sliding cooperation between the other two first slots 11 and the two second sliding pins 13. Therefore, when the inner side of the weighing plate 4 carries a single aquatic product of different weights, it can drive the lifting plate 202 of the driving mechanism to move up different strokes, and the lifting plate 202 drives the second piston cylinder 203, the second push rod 205, and the drag reduction roller 206 to move upward synchronously;

[0050] When the driving mechanism that moves up to different heights moves to a trigger mechanism at the same height, the drag reduction roller 206 in the driving mechanism will contact the pushing inclined surface 304 in the trigger mechanism at the same height. Under the guiding action of the pushing inclined surface 304, a thrust can be applied to the drag reduction roller 206, and the drag reduction roller 206 pushes the second push rod 205 to move toward the inside of the second piston cylinder 203. The second push rod 205 drives the second piston plate 204 to move. The second piston plate 204 can press the hydraulic oil at one end of the inner side of the second piston cylinder 203 into one end of the inner side of the first piston cylinder 103 of the flip mechanism through the connecting pipe 207. The hydraulic The oil pushes the first piston plate 104 of the turnover mechanism to move, and the first piston plate 104 drives the first push rod 106 to extend and move toward the inner side of the rotating cylinder 101. At the same time, the first piston plate 104 compresses the return spring 105, and the limit block 102 can limit the rotation of the first push rod 106, so that the first push rod 106 moves horizontally along a straight line. The first push rod 106 is slidably matched between two reversing sliding pins 107 at one end and two spiral grooves 108. When the first push rod 106 moves toward the inner side of the rotating cylinder 101, it can drive the rotating cylinder 101 to rotate a certain angle, and the rotating cylinder 101 drives the weighing plate 4 to rotate a certain angle (such as Figure 6 As shown), the aquatic products carried on the upper side of the weighing plate 4 can be poured down, so that the aquatic products slide to the upper side of the discharge slide plate 17 corresponding to the trigger mechanism at that location, thereby realizing the function of automatically classifying and feeding aquatic products of different weights;

[0051] A single aquatic product with a heavier weight will press the weighing plate 4 down a greater stroke, thereby driving the driving mechanism to move up a greater stroke. A single aquatic product with a lighter weight will press the weighing plate 4 down a smaller stroke, thereby driving the driving mechanism to move up a smaller stroke. By adjusting the height of the trigger push plate 302 of each trigger mechanism, a trigger push plate 302 with a higher height can trigger the driving mechanism with a greater upward stroke, thereby pouring down the heavier aquatic product, and a trigger push plate 302 with a lower height can trigger the driving mechanism with a smaller upward stroke, thereby pouring down the lighter aquatic product. Before feeding the aquatic product, the device can automatically classify the individual aquatic products of different weights by weight, has a simple structure, higher efficiency, and more stable operation.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
