Description

Technical Field

[0001] This invention relates to the field of cocoon boiling technology, specifically to a rotating cocoon boiling tank and a sealing device for the tank lid, a control method, and an operating method. Background Technology

[0002] In the raw silk production process, cocoon boiling is an extremely important step. The quality of cocoon boiling directly affects the yield, quality, and consumption of silk reeling. Cocoon boiling utilizes water, heat, or auxiliaries to treat the cocoon silk for a certain period of time, appropriately swelling and dissolving the sericin, weakening the binding between sericin particles, reducing its adhesive strength, and improving uneven adhesion. This allows the cocoon silk to continuously and sequentially separate at the adhesion points and bundle together to form raw silk during reeling.

[0003] The existing cocoon boiling system includes a boiling tank and a piping system that works in conjunction with the boiling tank. The existing boiling tank and piping system can connect a vacuum pump, a water pump, steam, water supply and drainage to the tank body. A vacuum is generated in the tank body, and steam and water at different temperatures are introduced to complete the boiling process, such as permeation, water discharge, steaming, and adjustment and protection. This causes the sericin to swell, expand, and dissolve appropriately, thus achieving the purpose of boiling the silkworm cocoons. However, the existing boiling tank and tank lid are mainly opened and closed manually, and automatic sealing cannot be achieved. Summary of the Invention

[0004] The purpose of this invention is to provide a rotating cocoon-cooking tank with a sealing device, control method, and operation method. It improves upon existing cocoon-cooking tanks by creating a rotating tank with a sealing device. As the tank rotates from the cocoon-adding position to the cocoon-cooking position, the lid is lowered via a track. When the tank reaches the cooking position, the lid locks, sealing the tank. Simultaneously, the piping system is connected and sealed. This system connects a vacuum pump, water pump, steam, and water supply / drainage to the tank, creating a vacuum within the tank and introducing steam and water at different temperatures. This completes the cocoon-cooking process, including permeation, water discharge, steaming, and adjustment / protection, causing the sericin to swell, expand, and dissolve appropriately, thus cooking the cocoons. After cooking, the tank and lid separate. The tank rotates to the cocoon-discharging position to pour out the cooked cocoons. Then, the tank reverses and returns to its original position, passing the cooking position and pulling the lid back to its original position. The tank then returns to the cocoon-adding position, preparing for the next cocoon-cooking cycle.

[0005] This invention is achieved through the following technical solution: a rotating tank and lid sealing device for boiling cocoons, mounted on a frame, includes a tank assembly, a lid that cooperates with the tank assembly, a lid track for installing the lid, and a clamping device mounted on the lid track; the tank assembly includes a tank rotating shaft Q1, a tank body, a tank opening flange, and a tank rotating motor. Two tank rotating shafts Q1 are symmetrically arranged on the tank body, and the tank rotating motor is driven by the tank rotating shafts Q1. The tank opening flange is located on the opening of the tank body, and on opposite sides of the tank opening flange are respectively arranged a tank opening puller signal shaft and a tank opening puller that cooperates with the tank opening puller signal shaft. The axis of the tank rotating shaft Q1 on the tank body is parallel to the axis of the tank opening puller signal shaft.

[0006] The function of the tank body is as follows: (1) When the tank body rotates from the cocoon-adding position to the cocoon-cooking position by a certain angle, the tank opening pull block signal shaft installed on the tank opening flange pushes the tank cover support plate on the tank cover track to rotate, causing the tank cover to fall down, and at the same time driving the tank cover to move synchronously to the cocoon-cooking position.

[0007] (2) When the can rotates from the cocoon-out position to the cocoon-adding position, the can mouth pull block drives the can lid to move upward, so that the can lid returns to its original position.

[0008] To further improve the sealing device of the rotating cocoon boiling tank and the tank lid described in this invention, the following structure is specifically adopted: a positioning device is provided on the rotating shaft Q1 of the tank. The positioning device includes a positioning disk sleeved on the rotating shaft Q1 of the tank and a positioning limit switch provided on the frame. The positioning disk is provided with three positioning posts for indicating the cocoon adding position, the cocoon boiling position and the cocoon exiting position. During operation, the positioning posts contact and cooperate with the positioning limit switch to realize the status positioning of the cocoon adding position, the cocoon boiling position or the cocoon exiting position.

[0009] To further improve the sealing device of the rotating cocoon boiling tank and the lid described in this invention, the following structure is specifically adopted: the lid includes a lid body and a lid connecting plate, a lid pressing plate and a lid hanging groove covering the surface of the lid body. A lid flange is provided on the side of the lid body that matches the lid opening flange. An upper guide bearing and a lower guide bearing that match the lid track are also installed on the lid.

[0010] To further improve the sealing device of the rotating cocoon boiling tank and the lid described in this invention, the following structure is specifically adopted: the lid track includes two track support plates arranged opposite each other, a track guide groove is installed on the track support plate to cooperate with the movement of the lid, a lid support plate is installed on the outside of the track support plate through the lid support plate rotation shaft Q2, and an upper track connecting plate and a lower track connecting plate are arranged between the two track support plates.

[0011] The function of the can lid track is as follows: (1) Unlock the lid and let it fall.

[0012] (2) The tank body drives the tank cover to move from the cocoon adding position to the cocoon boiling position, from the cocoon boiling position to the cocoon exiting position, and from the cocoon exiting position to the cocoon adding position, ensuring that the tank cover moves along a fixed path within the tank cover track.

[0013] To further improve the sealing device of the rotating cocoon boiling tank and the lid described in this invention, the following structure is specifically adopted: the pressing device includes a lid pressing shaft Q3, a lid pressing cam sleeved on the lid pressing shaft Q3, and a lid pressing motor that is driven and cooperates with the lid pressing shaft Q3.

[0014] The function of the pressing device is as follows: when the tank body and the tank lid reach the position for boiling cocoons, the pressing motor drives the pressing shaft Q3 to rotate 180 degrees. The diameter of the pressing cam changes during the rotation to press / release the tank lid, thereby achieving sealing / unsealing.

[0015] To further improve the implementation of the cocoon-boiling rotating tank and lid sealing device described in this invention, the following structure is specifically adopted: it also includes a PLC controller for controlling the cocoon-boiling rotating tank and lid sealing device.

[0016] The rotating tank positioning control method, which controls the cocoon-cooking rotating tank and the tank lid sealing device to achieve the cocoon-cooking control process, includes the following steps: 1) When the cocoon cooking is started, the PLC controller sends a signal to the tank rotation motor, and the tank starts to rotate forward from the cocoon adding position to the cocoon cooking position. At this time, the tank rotation shaft Q1 drives the positioning plate to rotate together. When it rotates to the cocoon cooking position, the positioning column representing the cocoon cooking position contacts the positioning limit switch. The positioning limit switch sends a signal to the PLC controller, and the PLC controller controls the tank rotation motor to stop running. 2) After the cocoons are cooked, the PLC controller sends a cocoon-out signal, and the tank rotates forward again, from the cocoon-cooking position to the cocoon-out position. The positioning column representing the cocoon-out position contacts the positioning limit switch, and the positioning limit switch sends a signal to the PLC controller. The PLC controller controls the tank rotation motor to stop running. 3) After the cooked cocoons are poured out, the PLC controller sends a signal, the tank rotation motor starts running, the tank reverses, the cocoon discharge position → cocoon cooking position → cocoon adding position, the tank returns to the cocoon adding position, the positioning column representing the cocoon adding position contacts the positioning limit switch, the PLC controller controls the tank rotation motor to stop running, and one cocoon cooking cycle is completed.

[0017] The operating method of the rotating cocoon boiling tank and the tank lid sealing device, based on the aforementioned rotating cocoon boiling tank and the tank lid sealing device, realizes the actuation cooperation between the tank device and the tank lid, including the following steps: (S1) Sealing between the can lid and the can body: (S1.1) When the tank is in the cocoon-adding position, the tank opening is facing upwards and the tank cover is at the upper end of the tank cover track. After adding silkworm cocoons into the tank, press the start button. Driven by the tank rotation motor, the tank moves around the tank rotation axis Q1 from the cocoon-adding position to the cocoon-cooking position and achieves sealing between the tank and the tank cover. (S1.2) During the rotation of the tank, the signal shaft of the tank opening pull block hits the tank cover plate, which pushes the tank cover plate to rotate around the tank cover plate rotation axis Q2. The tank cover is released from the support of the tank cover plate and falls under the action of gravity and is caught in the tank cover hanging groove by the tank opening pull block, so that the tank cover moves synchronously with the tank body in the tank cover track to the cocoon boiling position. (S1.3) At the same time, the capping motor starts, driving the capping shaft Q3 to rotate 180 degrees. The capping cam is installed on the capping shaft Q3. The capping cam presses the can lid and the can body together to achieve a seal between the can lid and the can body. (S2) The tank body separates from the tank lid: (S2.1) When the cocoon emerges, the capping motor starts, driving the capping shaft Q3 to rotate 180 degrees, the capping cam is released, and the can cover separates from the can body; (S2.2) Driven by the tank rotation motor, the tank rotates around the tank rotation axis Q1. Since the tank cover can only move within the tank cover track, the tank cover separates from the tank body. The tank body rotates from the cocoon boiling position to the cocoon exit position, thus separating the tank body from the tank cover. (S3) Return the tank body and lid to their original positions: After the cocoon emerges, the tank moves in the opposite direction to the cocoon-adding position. At this time, the upper edge of the tank flange supports the tank cover connecting plate and moves upward. As the tank cover moves upward, the tank opening puller extends into the tank cover hanging groove. When the tank body rotates to a certain angle, the tank opening puller will separate from the tank cover hanging groove. The tank opening puller supports the tank cover hanging groove, ensuring that the tank cover can continue to move upward along the tank cover track until the tank cover support plate can hook the guide bearing on the tank cover, realizing the return of the tank cover to its original position.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects: This invention improves upon existing cocoon-cooking tanks by incorporating a rotating tank body and a sealing lid. As the tank rotates from the cocoon-adding position to the cocoon-cooking position, the lid descends via a track. Upon reaching the cooking position, the lid locks, sealing the tank. Simultaneously, the piping system is connected and sealed, linking a vacuum pump, water pump, steam, and water supply / drainage to the tank. This creates a vacuum within the tank, allowing steam and water at varying temperatures to permeate, release water, and perform cooking processes, including adjustment and protection. This process causes the sericin to swell, expand, and dissolve appropriately, achieving the goal of cooking the cocoons thoroughly. After cooking, the tank body and lid separate. The tank rotates to the cocoon-discharging position to pour out the cooked cocoons. Then, the tank reverses and returns to its original position, passing the cooking position and pulling the lid back to its original position. The tank then returns to the cocoon-adding position, preparing for the next cocoon-cooking cycle.

[0019] Based on the need for automation and continuous operation of the cocoon boiling process, this invention sets up a rotating cocoon boiling tank and a sealing device for the tank lid, so that the rotating cocoon boiling tank can achieve a tight seal between the tank body and the tank lid during rotation, thus realizing the technical requirement that the cocoon boiling tank (tank body) is in a sealed state when the cocoons are boiling.

[0020] Throughout the entire cocoon boiling process, the present invention, through the design of the cocoon boiling tank body driving the tank lid, can ensure that the cocoon boiling tank (tank body) and the tank lid always remain in a synchronized state, improve the effectiveness of the sealing between the tank body and the tank lid, and achieve the technical requirement that the rotating cocoon boiling tank be in a sealed state when the cocoon boiling position is in the cocoon boiling position.

[0021] This invention can meet the process requirements of water discharge from the cocoon cavity (steam extraction from the top and bottom or steam flow from the bottom and top) and cocoon layer cooking during the cocoon boiling process.

[0022] This invention employs PLC control technology to achieve rotational positioning control of the cocoon-cooking rotating tank, solving the problem of precise positioning of the tank during cocoon feeding, cooking, and unloading. It also allows for more flexible control of the tank's rotation angle, enabling automated and continuous cocoon cooking. Attached Figure Description

[0043] Example 1: The rotating tank for boiling cocoons and the sealing device for the tank lid are combined. Figure 2As shown, the device, mounted on frame 1, includes a tank assembly, a can cover that mates with the tank assembly, a can cover track for mounting the can cover, and a clamping device mounted on the can cover track. The frame 1 is used to install and fix the tank body 3, the can cover track, and the clamping device. The tank assembly includes a tank rotating shaft Q12, a tank body 3, a can opening flange 4, and a tank rotating motor. Two tank rotating shafts Q12 are symmetrically arranged on the tank body 3. The can opening motor is driven by the tank rotating shafts Q12. The can opening flange 4 is located at the opening of the tank body 3. On opposite sides of the can opening flange 4, a can opening pull-block signal shaft 6 and a can opening pull-block 5 that mates with the can opening pull-block signal shaft 6 are respectively arranged. The axis of the tank rotating shaft Q12 and the axis of the can opening pull-block signal shaft 6 are parallel on the tank body 3.

[0044] As a preferred design, the rotating cocoon-boiling tank and lid sealing device mainly consists of four parts: the tank body, the lid, the lid track, and the clamping device. Figure 2 As shown.

[0045] The tank assembly mainly consists of a tank rotating shaft Q12, a tank body 3, a tank opening flange 4, and a tank rotating motor. A tank opening lever 5 and a tank opening lever signal shaft 6 are installed on the tank opening flange 4, one on each side of the tank opening flange 4.

[0046] The function of the tank body is as follows: (1) When the tank body 3 rotates from the cocoon adding position to the cocoon cooking position by a certain angle, the tank opening pulling block signal shaft 6 installed on the tank opening flange 4 pushes the tank cover support plate 15 on the tank cover track to rotate, so that the tank cover falls down and at the same time drives the tank cover to move synchronously to the cocoon cooking position.

[0047] (2) When the can body 3 rotates from the cocoon-out position to the cocoon-adding position, the can mouth pull block 5 drives the can lid to move upward, so that the can lid returns to its original position.

[0048] During the decompression and cocoon boiling process, silkworm cocoons are placed into a rotating container. The container is designed with positions for adding cocoons, boiling cocoons, and removing cocoons. Figure 1As shown, (a) is the cocoon-adding position, (b) is the cocoon-cooking position, and (c) is the cocoon-exiting position. The tank rotation and positioning are controlled by a PLC. As the tank rotates from the cocoon-adding position to the cocoon-cooking position, the lid falls via a track. When the tank reaches the cocoon-cooking position, the lid locks, sealing the tank. Simultaneously, the piping system connects and seals, linking the vacuum pump, water pump, steam, and water supply / drainage to the tank. A vacuum is created within the tank, and steam and water at different temperatures are introduced to complete the cocoon-cooking process, including permeation, water discharge, steaming, and adjustment / protection. This causes the sericin to swell, expand, and dissolve appropriately, achieving the goal of cooking the cocoons. After cooking, the tank separates from the lid, and the tank rotates to the cocoon-exiting position to pour out the cooked cocoons. Then, the tank reverses and returns to its original position, passing the cocoon-cooking position and pulling the lid back to its original position. The tank then returns to the cocoon-adding position, preparing for the next cocoon-cooking cycle.

[0049] Example 2: This embodiment is a further optimization based on the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. Figure 2 As shown, in order to better realize the sealing device of the rotating tank and the lid of the cocoon boiling machine described in this invention, the following structure is specially adopted: a positioning device is provided on the rotating shaft Q12 of the tank. The positioning device includes a positioning disk 22 sleeved on the rotating shaft Q12 of the tank and a positioning limit switch 21 provided on the frame 1. Three positioning columns (cocoon adding positioning signal column 23, cocoon boiling positioning signal column 24, and cocoon exiting positioning signal column 25) are provided on the positioning disk 22 for indicating the cocoon adding position, cocoon boiling position, and cocoon exiting position. During operation, the positioning column and the positioning limit switch (21) contact and cooperate to realize the positioning of the cocoon adding position, cocoon boiling position, or cocoon exiting position.

[0050] The tank 3 is positioned at the cocoon-adding, cocoon-cooking, and cocoon-exiting positions, and its rotation and stopping are mainly controlled by a PLC controller. A positioning device is installed at the tank 3's rotation axis Q12. This positioning device rotates synchronously with the tank 3, providing real-time feedback on the tank 3's rotation angle. The positioning device mainly consists of a positioning limit switch 21 and a positioning disk 22. The positioning disk 22 has three positioning posts (cocoon-adding positioning signal post 23, cocoon-cooking positioning signal post 24, and cocoon-exiting positioning signal post 25), arranged at a certain angle with the tank's rotation axis Q12 as the center point. When each positioning post contacts the positioning limit switch 21, it represents one of the three position states of the tank: cocoon-adding, cocoon-cooking, or cocoon-exiting. Figure 7 As shown.

[0051] Example 3: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. Figure 2As shown, to further improve the sealing device of the rotating cocoon boiling tank and the lid described in this invention, the following structure is specifically adopted: The lid includes a lid body and a lid connecting plate 8, a lid pressing plate 9 and a lid hanging groove 10 covering the surface of the lid body. A lid flange 11 is provided on the side of the lid body that cooperates with the lid opening flange 4. A lid upper guide bearing 7 and a lid lower guide bearing 17 that cooperate with the lid track are also installed on the lid.

[0052] As a preferred design, the can lid includes a lid body, with upper guide bearings 7 and lower guide bearings 17 installed at the upper and lower ends of the lid body to support the movement and positioning of the can lid within the can lid track. The outer surface of the can lid is covered with a can lid connecting plate 8, a can lid clamping plate 9, and a can lid hanging groove 10, while the inner surface has a can lid flange 11. Figure 3 As shown.

[0053] Example 4: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. Furthermore, to better realize the cocoon-boiling rotating tank and tank lid sealing device described in this invention, combined with… Figure 2 As shown, the following structure is specifically adopted: the can lid track includes two track support plates 13 arranged opposite to each other, a track guide groove 12 that cooperates with the movement of the can lid is installed on the track support plate 13, a can lid support plate 15 is installed on the outside of the track support plate 13 through the can lid support plate rotation shaft Q216, and an upper track connecting plate 14 and a lower track connecting plate 20 are arranged between the two track support plates 13.

[0054] The can lid track includes left and right track support plates 13, with track guide grooves 12 welded onto the left and right track support plates 13 to form track grooves. Upper guide bearings 7 and lower guide bearings 17 of the can lid roll within the track grooves. A can lid support plate 15 is provided at the upper end of the track support plates, and the can lid support plate 15 can rotate around the can lid support plate rotation axis Q216. The distance between the left and right track support plates is kept constant by the upper track connecting plate 14 and the lower track connecting plate 20.

[0055] The function of the can lid track is as follows: (1) Unlock the lid and let it fall.

[0056] (2) The tank body 3 drives the tank cover to move from the cocoon adding position to the cocoon boiling position, from the cocoon boiling position to the cocoon exiting position, and from the cocoon exiting position to the cocoon adding position, ensuring that the tank cover moves along a fixed path within the tank cover track.

[0057] Example 5: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the rotating tank and lid sealing device for boiling cocoons described in this invention, the following structure is specifically adopted: The pressing device includes a lid shaft Q318, a lid cam 19 sleeved on the lid shaft Q318, and a lid motor that is driven and cooperates with the lid shaft Q318.

[0058] The track support plate 13 is provided with a groove for engaging the cover shaft Q318.

[0059] The function of the pressing device is as follows: when the tank body 3 and the tank cover reach the cocoon boiling position, the pressing motor drives the pressing shaft Q318 to rotate 180 degrees. The diameter of the pressing cam 19 changes during the rotation to press / release the tank cover, thereby achieving sealing / unsealing. The rotation of the tank body 3 drives the tank cover to run in the tank cover track. When it reaches the cocoon boiling position, the pressing shaft Q318 drives the pressing cam 19 to rotate, pressing the tank cover to achieve sealing of the tank body.

[0060] Example 6: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. In order to better realize the cocoon boiling rotating tank and tank lid sealing device of the present invention, the following configuration structure is specially adopted: it also includes a PLC controller for controlling the cocoon boiling rotating tank and tank lid sealing device.

[0061] Example 7: This embodiment is a further optimization based on any of the above embodiments. The similarities with the aforementioned technical solutions will not be repeated here. Figure 2 As shown, tank 3 is positioned at the cocoon-adding position, cocoon-cooking position, and cocoon-exit position. The rotation and stopping of tank 3 are mainly controlled by a PLC controller. A positioning device is installed at the rotation axis Q12 of tank 3. This positioning device rotates synchronously with tank 3, providing real-time feedback on the rotation angle of tank 3. The positioning device mainly consists of a positioning limit switch 21 and a positioning disk 22. The positioning disk 22 is designed with three positioning posts (cocoon-adding positioning signal post 23, cocoon-cooking positioning signal post 24, and cocoon-exit positioning signal post 25), arranged at a certain angle with the rotation axis Q12 as the center point. When each positioning post contacts the positioning limit switch 21, it represents one of the three position states of the tank: cocoon-adding, cocoon-cooking, or cocoon-exiting. Figure 7 As shown.

[0062] The rotating tank positioning control method achieves the cocoon-cooking control process by controlling the rotating tank and the tank lid sealing device. Figure 8 As shown, it includes the following steps: 1) When the cocoon cooking is started (by pressing the start cocoon cooking button of the control system that works with the PLC controller), the PLC controller sends a signal to the tank rotation motor, and the tank starts to rotate forward from the cocoon adding position to the cocoon cooking position. At this time, the tank rotation shaft Q12 drives the positioning plate 22 to rotate together. When it rotates to the cocoon cooking position, the positioning column (cocoon cooking positioning signal column 24) representing the cocoon cooking position contacts the positioning limit switch 21. The positioning limit switch 21 sends a signal to the PLC controller, and the PLC controller controls the tank rotation motor to stop running. 2) After the cocoons are cooked, the PLC controller sends a cocoon-out signal, and the tank 3 rotates forward again, from the cocoon-cooking position to the cocoon-out position. The positioning column (cocoon-out positioning signal column 25) representing the cocoon-out position contacts the positioning limit switch 21. The positioning limit switch 21 sends a signal to the PLC controller, and the PLC controller controls the tank rotation motor to stop running. 3) After the cooked cocoons are poured out, the PLC controller sends a signal, the tank rotation motor starts running, the tank 3 reverses, from the cocoon discharge position to the cocoon cooking position to the cocoon adding position. The tank 3 returns to the cocoon adding position, the positioning column (cocoon adding positioning signal column 23) representing the cocoon adding position contacts the positioning limit switch 21, the PLC controller controls the tank rotation motor to stop running, and one cocoon cooking cycle is completed.

[0063] Example 8: This embodiment is a further optimization based on any one of embodiments 1 to 6. The similarities with the aforementioned technical solutions will not be repeated here. The method for operating the rotating cocoon-boiling tank and the tank lid sealing device achieves the actuation coordination between the tank device and the tank lid based on the aforementioned rotating cocoon-boiling tank and tank lid sealing device. During the cocoon-boiling process, the tank 3 drives the tank lid to run within the tank lid track, combined with... Figure 2 As shown, it includes the following steps: (S1) Sealing between the can lid and the can body: (S1.1) When tank 3 is in the cocoon-adding position, the tank opening faces upwards, and the tank cover is at the upper end of the tank cover track. Figure 4a After adding silkworm cocoons into tank 3, pressing the start button causes tank 3 to rotate around the tank rotation axis Q12, moving from the cocoon-adding position to the cocoon-cooking position and sealing the tank and lid. Figure 4b , Figure 4c As shown; (S1.2) During the rotation of the tank body 3, the can opening pull-out signal shaft 6 strikes the can lid support plate 15, pushing the can lid support plate 15 to rotate around the can lid support plate rotation axis Q216 as the center, such as... Figure 5a As shown, the can lid detaches from the support of the can lid support plate 15, falls under the action of gravity, and is caught in the can lid hanging groove 10 by the can mouth puller 5, so that the can lid moves synchronously with the can body 3 to the cocoon boiling position within the can lid track, as shown. Figure 5b As shown; (S1.3) Simultaneously, the capping motor starts, driving the capping shaft Q318 to rotate 180 degrees. The capping cam 19 is installed on the capping shaft Q318, and the cam 19 presses the flanges (can opening flange 4, can cover flange 11) between the can cover and the can body 3 together, thus achieving a seal between the can cover and the can body 3. Figure 4c As shown; (S2) The tank body 3 separates from the tank lid: (S2.1) When the cocoon emerges (press the "Restart / Emerge" button when the cocoon emerges), the capping motor starts, driving the capping shaft Q318 to rotate 180 degrees, as shown. Figure 4c , Figure 4d As shown, the capping cam 19 is released, and the can cap separates from the can body 3; (S2.2) Driven by the tank rotation motor, the tank body 3 rotates around the tank rotation axis Q12. Since the tank lid can only move within the tank lid track, the tank lid separates from the tank body 3, and the tank body 3 rotates from the cocoon boiling position to the cocoon exit position, as shown. Figure 4d As shown, this allows the tank body 3 to detach from the tank cover; (S3) Return the tank body and lid to their original positions: After the cocoons have emerged, tank 3 moves in the opposite direction to the cocoon-adding position, as follows: Figure 4e As shown, at this time, the upper edge of the tank flange 4 supports the tank cover connecting plate 8 and moves upward, as... Figure 6 As shown in (a), during the upward movement of the can lid, the can opening puller 5 extends into the can lid hanging groove 10, as shown in (a). Figure 6 As shown in (b). When the can body 3 is rotated to a certain angle, the can opening puller 5 will separate from the can cover hanging groove 10, as shown. Figure 6 As shown in (c). The can opening puller 5 supports the can lid hanging groove 10, ensuring that the can lid can continue to move upward along the can lid track until the can lid support plate 15 can hook onto the guide bearing 7 on the can lid, realizing the can lid returning to its original position, as shown. Figure 6 As shown in (d).

6. The operating method of the rotating tank and lid sealing device for boiling cocoons, characterized in that: The actuation coordination between the tank body and the tank lid is achieved based on the rotating tank and lid sealing device for boiling cocoons as described in claim 4, including the following steps: (S1) Sealing between the can lid and the can body: (S1.1) When the tank (3) is in the cocoon-adding position, the tank opening is facing upward and the tank cover is at the upper end of the tank cover track. After adding silkworm cocoons into the tank (3), press the start button. The tank (3) will move from the cocoon-adding position to the cocoon-cooking position around the tank rotation axis Q1 (2) under the drive of the tank rotation motor and achieve the sealing of the tank and the tank cover. (S1.2) During the rotation of the tank body (3), the signal shaft (6) of the tank mouth pull block hits the can lid support plate (15), pushing the can lid support plate (15) to rotate around the can lid support plate rotation axis Q2 (16) as the center. The can lid is separated from the support of the can lid support plate (15), falls under the action of gravity and is caught in the can lid hanging groove (10) by the tank mouth pull block (5), so that the can lid moves synchronously with the tank body (3) to the cocoon boiling position in the can lid track. (S1.3) At the same time, the capping motor starts, driving the capping shaft Q3 (18) to rotate 180 degrees. The capping cam (19) is installed on the capping shaft Q3 (18). The capping cam (19) presses the can lid and the can body (3) together to achieve the seal between the can lid and the can body (3). (S2) The tank body (3) separates from the tank lid: (S2.1) When the cocoon emerges, the capping motor starts, driving the capping shaft Q3 (18) to rotate 180 degrees, the capping cam (19) is released, and the can lid is separated from the can body (3); (S2.2) The tank body (3) rotates around the tank body rotation axis Q1 (2) under the drive of the tank body rotation motor. Since the tank cover can only move within the tank cover track, the tank cover separates from the tank body (3). The tank body (3) rotates from the cocoon boiling position to the cocoon exit position, thus realizing the separation of the tank body (3) from the tank cover. (S3) Return the tank body and lid to their original positions: After the cocoon emerges, the tank (3) moves in the opposite direction to the cocoon adding position. At this time, the upper edge of the tank opening flange (4) supports the tank cover connecting plate (8) and moves upward. During the upward movement of the tank cover, the tank opening pull block (5) extends into the tank cover hanging groove (10). When the tank body (3) turns to a certain angle, the tank opening pull block (5) will separate from the tank cover hanging groove (10). The tank opening pull block (5) supports the tank cover hanging groove (10) to ensure that the tank cover can continue to move upward along the tank cover track until the tank cover support plate (15) can hang on the guide bearing (7) on the tank cover, thus realizing the return of the tank cover.
