[0037] The mixing and spreading mechanism 6 includes a mixing box 61, which is fixedly connected to the lower surface of the O-shaped slide plate 57. A support ring 62 is fixedly connected to the upper end of the interior of the mixing box 61. A rotating rod 63 is rotatably connected inside the support ring 62.

The ratchet ring 64 slides downward inside mixing box 61 via spring telescopic rod 613. The brush on the surface of telescopic pressure plate 614 faces downward, squeezing out the seasoning while continuously applying seasoning to the salted kelp. As the salted kelp is laid layer by layer, the brush on telescopic pressure plate 614 applies seasoning to the salted kelp layer by layer, further improving work efficiency.

[0038] A cross ring 68 is rotatably connected inside the support ring 62. The telescopic end of the telescopic threaded rod 65 is threadedly connected to the cross ring 68.

The two telescopic pressure plates 614 move back and forth alternately, which can mix the liquid seasonings in the mixing box 61 together. This not only saves mixing time but also improves work efficiency. Putting all the seasonings together at the same time can also enhance the flavor and prevent the salted kelp from losing its flavor.

[0040] The method of use and advantages of this invention: The continuous seasoning addition device operates as follows:

[0041] In use, individual salted kelp are first transported intermittently via electric conveyor belt 2. When electric conveyor belt 2 is operating, it drives pulley 1 31 to rotate. Pulley 1 31 drives pulley 2 33 to rotate via transmission belt 34. When pulley 2 33 rotates, it simultaneously drives eccentric wheel 35 to rotate on L-shaped fixed rod 32. When eccentric wheel 35 rotates, it pushes connecting rod 310 to swing. Connecting rod 310 drives connecting rod 1 36 to swing simultaneously. Connecting rod 1 36 drives T-shaped rod 38 to operate. The end of T-shaped rod 38 is limited by connecting rod 2 37. When eccentric wheel 35 rotates, it drives the limited T-shaped rod 38 to reciprocate in a U-shape on L-shaped fixed rod 32. When T-shaped rod 38 moves to the direction of inclined trough frame 311.

[0042] As the T-shaped rod 38 moves downward, it drives the slide rod 312 into the inclined slot frame 311 through the slot 39, squeezing the slide rod 312 to slide within the slot 39. When the slide rod 312 slides, it drives the outer shell 41 to move towards the salted kelp. At the same time, the cylinder 42 pulls the slider 43. When the slider 43 is pulled, it drives the hinged L-shaped connecting rod 44. When the L-shaped connecting rod 44 is pulled, it rotates around its middle. The other end of the L-shaped connecting rod 44 drives the clamping claw 46 to rotate. When the two clamping claws 46 rotate, they move relative to each other through the limiting of the connecting rod 45, clamping the salted kelp. Then, when the T-shaped rod 38 reciprocates in a U-shape, the salted kelp is placed into the placement table 1 and repeatedly stacked, greatly reducing the kelp placement time and improving work efficiency.

[0043] Then, the drive motor 52 drives the transmission wheel 53 to rotate. The rotation of the transmission wheel 53 drives the transmission belt 55 to operate through the transmission wheel 54. When the transmission belt 55 operates, it drives the push rod 56 to follow the trajectory of the transmission belt 55. At the same time, it squeezes the O-shaped slide plate 57 to slide inside the support frame 51. When the push rod 56 rotates the transmission belt 55 and the transmission wheel 54, it will also rotate inside the O-shaped slide plate 57, causing the O-shaped slide plate 57 to move back and forth inside the support frame 51, and to be out of sync with the reciprocating motion of the T-shaped rod 38. When the O-shaped slide plate 57 drives the mixing box 61 to move in the direction of the electric conveyor belt 2, the ratchet ring 64 first rotates through the rack 58. When the ratchet ring 64 rotates in the forward direction, it is locked with the pawl 66. However, the pawl 67 cannot lock with the ratchet ring 64. The ratchet ring 64 will then drive the rotating rod 63 to rotate through the pawl 66. When the rotating rod 63 rotates, it drives the cross ring 68 to rotate. At this time, the cross ring 68 cannot drive the telescopic screw. When the grooved rod 65 rotates, the cross ring 68 rotates, driving the two gears 610 to rotate. The gears 610 rotate on the surface of the cross ring 68 via meshing gear rings 69. The rotation of the gears 610 drives the eccentric sliding rod 611 to reciprocate left and right on the surface of the support ring 62. The two sliding rods 611 are staggered. When the cross ring 68 drives the gears 610 to rotate, the gears 610 themselves also rotate on the cross ring 68. Therefore, the gears 610 drive the sliding rods 611 to reciprocate. The reciprocating movement of the sliding rods 611 drives the spring telescopic rod 613 to move via the T-shaped support rod 612. The spring telescopic rod 613 drives the telescopic pressure plate 614 to reciprocate. The two telescopic pressure plates 614 move back and forth alternately, mixing the liquid seasonings (such as vinegar, soy sauce, cooking wine, etc.) in the mixing box 61 together. This not only saves mixing time but also improves work efficiency. Placing all the seasonings together simultaneously also enhances the flavor and prevents the salted kelp from losing its distinct flavor.

[0044] Finally, when the O-shaped sliding plate 57 moves the mixing box 61 in another direction, the ratchet ring 64 rotates again. When the ratchet ring 64 rotates in the opposite direction, it engages with the second pawl 67, while the first pawl 66 cannot engage with the ratchet ring 64. The second pawl 67 drives the telescopic threaded rod 65 to rotate. The telescopic threaded rod 65 rotates and moves downward through the thread within the cross ring 68. When the telescopic threaded rod 65 rotates downward, it drives the caliper rod 617 to move downward. The caliper rod 617 presses down on the telescopic rod 616. When the telescopic rod 616 is pressed down, it presses down on the hinge block 615. The hinge block 615 rotates, causing the telescopic pressure plate 614 to rotate. The telescopic pressure plate 614 rotates 90 degrees on the surface of the spring telescopic rod 613, and at the same time slides downward inside the mixing box 61 via the spring telescopic rod 613. The brush on the surface of the telescopic pressure plate 614 faces downward, squeezing out the seasoning while continuously applying the seasoning to the salted kelp. As the salted kelp is laid layer by layer, the brush on the telescopic pressure plate 614 will apply the seasoning to the salted kelp layer by layer, further improving work efficiency.
