Furthermore, the terms "first," "second," "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections, direct connections, indirect connections via an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0037] refer to Figure 1 As shown, an embodiment of the present invention provides a pressure roller pneumatic integrated automatic cocoon picking device, including a first frame 1, a conveying mechanism 2, a cocoon picking roller 3, a first motor 4 and an air generator 5.

[0038] The first frame 1 is used to support the installation of other components and can be made into a frame structure. A baffle 11 is installed on each side of the first frame 1 in the width direction. The two baffles 11 are parallel to each other and form a conveying channel with the first frame 1. The width of the conveying channel is slightly wider than the width of the grid cluster.

[0039] refer to Figure 2 As shown, the conveying mechanism 2 includes rollers 21, a support shaft 22, pulleys 23, a transmission belt 24, and a second motor 25. The rollers 21 are rotatably supported on the inner side of the baffles 11 by the support shafts 22. Each baffle 11 is provided with multiple rollers 21 spaced apart along the length of the conveying channel. The rollers 21 on the two baffles 11 are symmetrical. There are two second motors 25, one at each end of the two baffles 11. There are multiple pulleys 23, each mounted on the support shaft 22 and on the output shaft of the second motor 25. Adjacent pulleys 23 on the same side of the first frame 1 are connected by a transmission belt 24. In this way, the second motor 25 can drive the rollers 21 to rotate. When the cocoon-containing square cluster enters the conveying channel, the rotation of the rollers 21 drives the square cluster forward.

[0040] refer to Figure 3The air inlet 33 is connected to the air inlet 33 by the air inlet 33 and the air outlet 34 is connected to the air inlet 33 by the air inlet 33. The air outlet 34 is connected to the air inlet 33 by the air inlet 33. The air outlet 34 is connected to the air inlet 33 by the air inlet 33. Both ends of the first roller 31 are rotatably supported on both sides of the first frame 1 and are located above the conveying passage.

[0041] The first motor 4 is supported on one side of the frame, and the output shaft of the first motor 4 is connected to one end of the first roller body 31 through a coupling, and can also be connected through a reducer transmission. In this way, the first motor 4 can drive the cocoon picking roller 3 to rotate.

[0042] The other end of the first roller 31 is connected to the air generator 5 via a ventilation duct, which in turn communicates with the air inlet channel 33. The gas generated by the air generator 5 enters the air inlet channel 33 through the ventilation duct, and is then ejected from the front end of the roller head 32 through the air outlet 34 and the exhaust channel 35. A flow control valve can be provided on the ventilation duct to facilitate control of the gas flow rate. During cocoon harvesting, the combined pressure from the roller head 32 and the force of the gas ejection separate the cocoons from the cells of the grid cluster, significantly improving separation effectiveness and efficiency.

[0043] The conveying channel is provided with a drop-out opening directly below the cocoon picking roller 3, and a guide cover 12 is provided below the drop-out opening. A partition is provided inside the guide cover 12, which divides its interior into two guide channels. The discharge openings of the two guide channels are respectively located on both sides of the guide cover 12, that is, respectively facing the two sides in the width direction of the first frame 1. In this way, the cocoons that fall into the guide cover 12 can flow into the two collection devices respectively through the guide channels, or a transmission device can be provided below the discharge opening of the guide channel to transport the cocoons to a designated location through the transmission device.

[0044] A roller brush 6 may be provided on the rear side of the cocoon picking roller 3 , and the roller brush 6 and the cocoon picking roller 3 are arranged side by side.

[0045] refer to Figure 4As shown, the roller brush 6 includes a second roller body 61 and bristles 62. The two ends of the second roller body 61 are rotatably supported on both sides of the first frame 1. The bristles 62 are arranged on the outer peripheral surface of the second roller body 61. A fourth motor 63 is provided on one side of the frame. The output shaft of the fourth motor 63 is connected to one end of the second roller body 61 through a coupling, and can also be connected through a reducer transmission. In this way, the fourth motor 63 can drive the roller brush 6 to rotate. When the roller brush 6 rotates, the bristles 62 contact the pressure roller head 32 on the cocoon picking roller 3, and brush off the silk on the pressure roller head 32 to ensure that the pressure roller head 32 is clean.

[0046] The first roller body 31 and the second roller body 61 can be processed into the same structure to improve versatility.

[0047] One end of the conveying channel is the feed end, and the other is the discharge end. A recovery trough 7 is provided at the discharge end of the conveying channel. A push rod 71 is provided on one side of the recovery trough 7, and a notch is provided on the sidewall on the other side. A grid cluster recovery mechanism 8 is provided next to the notch. In this embodiment, the discharge end is an inclined surface with a guide roller 13 installed on it. The guide roller 13 is provided to ensure smooth material flow at the discharge end.

[0048] The grid cluster recovery mechanism 8 includes a second frame, a conveyor chain 81, a driving wheel 82, a redirecting wheel 83, and a third motor. The driving wheel 82 is rotatably arranged at one end of the second frame, and the redirecting wheel 83 is rotatably supported at the other end of the second frame. The conveyor chain 81 passes around the driving wheel 82 and the redirecting wheel 83. The third motor is arranged on the second frame and adjacent to the driving wheel 82. The output shaft of the third motor is connected to one end of the rotating shaft of the driving wheel 82 through a coupling or a transmission connection through a reducer. The conveyor chain 81 is provided with a plurality of clamping blocks 84 along the circumference, and the clamping blocks 84 are provided with a card slot 841. Figure 5 As shown, a tightening mechanism is provided on the inner sidewall of the slot 841. The tightening mechanism includes a tightening spring 85 and a tightening block 86. The tightening block 86 is supported on one inner sidewall of the slot 841 by the tightening spring 85. The tightening block 86 can be formed into a wedge-shaped structure or an arc-shaped block to facilitate the insertion of the grid cluster into the slot 841.

[0049] The working principle of the pneumatic integrated pressure roller automatic cocoon picking device provided in the embodiment of the present invention is as follows:

[0050] The grid clusters filled with cocoons enter the conveying channel from the feed end of the conveying channel. The rollers 21 of the conveying mechanism 2 support the bottom sides of the grid clusters and drive them forward. When the grid clusters move to the cocoon picking roller 3, the rotating cocoon picking roller 3 separates the cocoons from the grids in the grid cluster under the combined action of the gas ejected from the pressure roller head 32 and the exhaust channel 35 in the pressure roller head 32. The fallen cocoons fall from the blanking port into the guide cover 12 and are guided to the corresponding position from the guide channel in the guide cover 12. The roller brush 6 can clean the cocoon picking roller 3. The silk on the pressure roller head 32 is cleaned to avoid silk entanglement that affects the cocoon picking effect. After the cocoons are picked, the grid cluster continues to be transported forward and slides from the discharge end of the conveying channel into the recovery tank 7. Then the push rod 71 withdraws it from the notch and enters the card slot 841 of the clamping block 84. The conveying chain 81 steps and rotates. Each time it steps, the clamping block 84 carrying the grid cluster moves forward, and the clamping block 84 adjacent to the rear moves to the recovery tank 7. The grid cluster is transported to the designated position by the conveying chain 81 for cleaning and recycling.

[0051] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
