The rotating pieces 564 of the two first rotating cylinders 563 move closer in opposite directions, and the gathering pieces 565 in the two fifth slide cylinders 566 also move closer in opposite directions. With the center point of the lucky bag as the center, the rotating piece 564 and the gathering piece 565 move closer to each other, so that the mouth of the bean skin bag after filling is gradually tightened to facilitate the tying mechanism 6 to tie it tightly.

[0049] At the same time, pneumatic scissors 61 are installed between the binding mechanism 6 and the dry scoop delivery mechanism 8; the main function of the pneumatic scissors 61 is to cut the dry scoop. The dry scoop delivery mechanism 8 includes a delivery bracket 84, a dry scoop box 86, and a delivery air claw 88.

The output end of the second stepper motor 81 is provided with a first drive wheel 82. The first drive wheel 82 and the first driven wheel 85 are connected by a second transmission belt 83 to ensure that the second stepper motor 81 can drive the first driven wheel 85 to rotate simultaneously. The dry scoop box 86 has a dry scoop groove 861 on the side near the binding mechanism 6. The outer edge of the first passive wheel 85 is provided with a raised edge 851, the width of which matches the width of the dry scoop groove 861; the second stepper motor 81 is started, so that the second stepper motor 81 rotates and drives the first driving wheel 82 to rotate. The first driving wheel 82 drives the first passive wheel 85 to rotate together through the second transmission belt 83. At this time, the raised edge 851 of the first passive wheel 85 is just in the dry scoop groove 861, and the dry scoop in the dry scoop groove 861 is delivered. A delivery cylinder 87 is also provided on one side of the delivery bracket 84. The output end of the delivery cylinder 87 is connected to a delivery claw 88. The claws in the delivery claw 88 correspond to the position of the dry scoop groove 861.

Subsequently, the dry scoop of a certain length is cut by the action of the pneumatic scissors 61.

[0050] In this embodiment, the frame platform 1 is also fixedly connected to a fixed frame 4 perpendicular thereto, and the fixed frame 4 is connected to a rotating mechanism 7 and at least two binding mechanisms 6; the rotating mechanism 7 is fixedly mounted on the fixed frame 4, and the rotating mechanism 7 includes a rotating mechanism motor 71, a first transmission belt 72, and a rotating connecting shaft 76. The rotating mechanism motor 71 drives the rotating connecting shaft 76 to rotate together by transmitting the first transmission belt 72; one end of the rotating connecting shaft 76 is connected to a connecting crossbar 73, and is connected to the middle position of the connecting crossbar 73. The two ends of the connecting crossbar 73 are each connected to a lifting cylinder 75, and the output end of the lifting cylinder 75 is fixedly connected to the binding mechanism 6. By driving the rotating mechanism motor 71, the rotating connecting shaft 76 and the connecting crossbar 73 are rotated, and the binding mechanisms 6 at both ends of the connecting crossbar 73 are rotated, so that the process is replaced and circulated.

[0051] The binding mechanism 6 includes a first pneumatic clamp assembly 67, a second pneumatic clamp assembly 68 and a binding mechanism fixing plate 65; the first pneumatic clamp assembly 67 is fixedly installed on the binding mechanism fixing plate 65, and the first pneumatic clamp assembly 67 includes an "L"-shaped fixing strip 671, a first pneumatic clamp 672 and a tensioning cylinder 675, the output end of the tensioning cylinder 675 is connected to one end of the "L"-shaped fixing strip 671, and the first pneumatic clamp 672 is connected to the other end of the "L"-shaped fixing strip 671. The second pneumatic clamp assembly 68 is connected to the frame platform 1 and includes: a second rotary cylinder 681, a third transmission belt 685, and a rotating shaft 686. The rotation output end of the second rotary cylinder 681 is provided with a second drive wheel 683. The bottom end of the rotating shaft 686 is provided with a second passive wheel 682. The second drive wheel 683 and the second passive wheel 682 form a transmission connection relationship through the third transmission belt 685. The other end of the rotating shaft 686 is fixedly connected to a second pneumatic clamp 687. The first pneumatic clamp assembly 67 clamps one end of the dried scoop, and is actuated by the tensioning cylinder 675 to stretch the dried scoop. The delivery claw 88 then delivers the dried scoop into the second pneumatic clamp assembly 68, and then controls the pneumatic scissors 61 to cut the dried scoop.

[0052] In this embodiment, the tying mechanism 6 further includes a gourd winding sleeve 62 and a retracting rod 64. The gourd winding sleeve 62 is arranged at the bottom of the tying mechanism fixing plate 65, on one side of the first pneumatic clamp 672.

The gourd stripping ring 63 is connected to the retracting rod 64; the gourd stripping ring 63 is slidably connected to the gourd winding sleeve 62. The dry gourd clamped by the first pneumatic clamp assembly 67 and the second pneumatic clamp assembly 68 is wound around the gourd winding sleeve 62 under the rotation of the second pneumatic clamp assembly 68, and is linked to the first pneumatic clamp assembly 67. Under the action of the cylinder, the second pneumatic clamp assembly 68 is moved in the vertical direction, and the movement and winding are performed alternately to achieve the preliminary winding and tying process. Subsequently, the rotating mechanism 7 is controlled to rotate 180 degrees, and the gourd wrapping sleeve 62 wrapped with the dry gourd moves to the top of the two sets of squeezing and closing bag opening mechanisms 56, with the center of the sleeve facing the bag opening of the lucky bag. The two sets of squeezing and closing bag opening mechanisms 56 are activated, completing the closing of the bag opening. At this time, the lifting cylinder 75 on one side is controlled to lower the binding mechanism 6 on that side, and the gourd stripping ring 63 and the retracting rod 64 are controlled to operate, causing the dry gourd wrapped around the gourd wrapping sleeve 62 to fall off. Then, the tensioning cylinder 675 is controlled to operate, causing the first pneumatic clamp 672 to move away from the bag opening, thereby tightening the bag opening and completing the binding operation.

[0053] In this embodiment, the lucky bag transport mechanism 3 includes a second rodless cylinder 31 and a second mounting plate 34 connected to the movable end of the second rodless cylinder 31.

After the tied lucky bag is squeezed and the bag opening mechanism 56 and the tying mechanism are returned to their original position, the conveyor belt mechanism 5 is operated to transport the lucky bag to the end of the conveyor belt mechanism 5. The lucky bag is then picked up from the bag carrying frame 55 by the transport claw 33 and transported to the designated area in a unified manner as the second rodless cylinder 31 moves.

The rotation mechanism drives the tying structure to rotate, and the tying mechanism on one side cooperates with the extrusion and bag-closing mechanism to realize the automatic tying and forming of the lucky bags. At the same time, the tying mechanism on the other side performs cutting and preliminary winding, saving the gap between production. Finally, the tied lucky bags are transported and collected in sequence by the lucky bag handling mechanism. The present invention realizes the mechanized and automatic processing flow of the lucky bags from bean curd to filling, tying and transporting during the production process through the cooperation of various mechanisms, freeing up manual labor and improving the production rate and product quality control.
