Description

Technical Field

[0001] The invention relates to the technical field of cocoon boiling, in particular to a cocoon boiling rotary tank body and tank cover sealing device structure, control method and operation method. Background Art

[0002] In the process of raw silk production, cocoon boiling is an extremely important process. The quality of cocoon boiling is directly related to the output, quality and consumption of silk reeling production. Cocoon boiling is to use the effect of water, heat or additives to properly swell and dissolve the sericin in the cocoons after a certain period of treatment, weaken the bond between the sericin particles, reduce its adhesion, and improve the uneven adhesion, so that the cocoons can be continuously separated in sequence according to the adhesion points during reeling, and bundled and embraced to form raw silk.

[0003] The existing cocoon boiling system includes a cocoon boiling tank and a pipeline system matched with the cocoon boiling tank. The existing cocoon boiling tank combined with the pipeline system can connect the vacuum pump, water pump, steam, water supply and drainage with the tank body, generate vacuum in the tank body, pass steam and water of different water temperatures, complete the cocoon boiling work such as infiltration, water spitting, boiling, adjustment and protection, so that the sericin swells, puffs and appropriately dissolves, so as to achieve the purpose of cooking the silk cocoons. However, the existing cocoon boiling tank and the tank cover are mainly opened and closed manually, and automatic sealing cannot be achieved. Summary of the invention

[0004] The purpose of the present invention is to provide a cocoon-boiling rotating tank body and a tank cover sealing device structure, a control method and an operation method, and to improve the existing cocoon-boiling tank to form a cocoon-boiling rotating tank body and a tank cover sealing device structure, so that when the tank body rotates from the cocoon-adding position to the cocoon-boiling position, the tank cover will drive it to fall through the tank cover track. When the tank body reaches the cocoon-boiling position, the tank cover is locked to achieve the sealing of the tank cover and the tank body. At the same time, the pipeline system is docked and sealed. The pipeline system connects the vacuum pump, water pump, steam, water supply and drainage with the tank body, generates a vacuum in the tank body, and introduces steam and water of different water temperatures to complete the cocoon-boiling work such as infiltration, water discharge, boiling, and adjustment protection, so that the sericin swells, puffs, and appropriately dissolves, so as to achieve the purpose of cooking the silkworm cocoons. After the cocoons are cooked, the tank body is separated from the tank cover, and the tank body rotates to the cocoon-discharging position to pour out the cooked cocoons, and then the tank body reverses and returns to the cocoon-boiling position to drive the tank cover, return the tank cover, and return the tank body to the cocoon-adding position to prepare for the next cocoon cooking.

[0005] The present invention is realized by the following technical scheme: a cocoon boiling rotating tank body and tank cover sealing device structure is installed on a frame, comprising a tank body device, a tank cover matched with the tank body loading, a tank cover track for installing the tank cover and a pressing device installed on the tank cover track; the tank body device comprises a tank body rotating shaft Q1, a tank body, a tank mouth flange and a tank body rotating motor, two tank body rotating shafts Q1 are symmetrically arranged on the tank body, the tank body rotating motor is matched with the tank body rotating shaft Q1 in transmission, the tank mouth flange is arranged on the tank mouth of the tank body, a tank mouth pull block signal shaft and a tank mouth pull block matched with the tank mouth pull block signal shaft are respectively arranged on opposite sides of the tank mouth flange, and the axis of the tank body rotating shaft Q1 and the axis of the tank mouth pull block signal shaft are parallel on the tank body.

[0006] The functions of the tank device are:

[0007] (1) When the tank body rotates a certain angle from the cocoon adding position to the cocoon boiling position, the tank mouth puller signal shaft installed on the tank mouth flange pushes the tank cover support plate on the tank cover track to rotate, causing the tank cover to fall, and at the same time drives the tank cover to move synchronously to the cocoon boiling position.

[0008] (2) When the tank body rotates from the cocoon-exiting position to the cocoon-adding position, the tank mouth puller drives the tank cover to move upward, so that the tank cover returns to its original position.

[0009] In order to better realize the cocoon boiling rotating tank body and tank cover sealing device structure of the present invention, the following setting structure is particularly adopted: a positioning device is arranged on the tank body rotating axis Q1, and the positioning device includes a positioning plate sleeved on the tank body rotating axis Q1 and a positioning stroke switch arranged on the frame, and three positioning columns for indicating the cocoon adding position, the cocoon boiling position and the cocoon emerging position are arranged on the positioning plate. During operation, the positioning columns contact and cooperate with the positioning stroke switches to realize the state positioning of the cocoon adding position, the cocoon boiling position or the cocoon emerging position.

[0010] In order to better realize the cocoon cooking rotating tank body and tank cover sealing device structure described in the present invention, the following setting structure is particularly adopted: the tank cover includes a cover body and a tank cover connecting plate, a tank cover pressing plate and a tank cover hanging groove covering the surface of the cover body, a tank cover flange is arranged on the side of the cover body that cooperates with the tank mouth flange, and a tank cover upper guide bearing and a tank cover lower guide bearing that cooperate with the tank cover track are also installed on the tank cover.

[0011] In order to better realize the cocoon cooking rotating tank body and tank cover sealing device structure of the present invention, the following setting structure is particularly adopted: the tank cover track includes two track support plates arranged opposite to each other, and a track guide groove cooperating with the tank cover movement is installed on the track support plate, and a tank cover support plate is installed on the outer side of the track support plate through the tank cover support plate rotation axis Q2, and a track upper connecting plate and a track lower connecting plate are arranged between the two track support plates.

[0012] Among them, the function of the tank cover track is:

[0013] (1) Unlock the tank lid and let it fall.

[0014] (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 in the tank cover track.

[0015] In order to better realize the cocoon cooking rotating tank body and tank cover sealing device structure of the present invention, the following setting structure is particularly adopted: the clamping device includes a capping shaft Q3, a capping cam sleeved on the capping shaft Q3, and a capping motor drivingly matched with the capping shaft Q3.

[0016] Among them, the function of the clamping device is: when the tank body and the tank cover reach the cocoon boiling position, the capping shaft O3 is driven by the capping motor to rotate 180 degrees, and the tank cover is clamped / loosened by the change in the diameter of the capping cam during rotation to achieve sealing / unsealing.

[0017] In order to better realize the cocoon cooking rotating tank body and tank cover sealing device structure of the present invention, the following setting structure is particularly adopted: it also includes a PLC controller for controlling the cocoon cooking rotating tank body and tank cover sealing device structure.

[0018] The method for controlling the positioning of the rotating tank body realizes the control process of cocoon cooking by controlling the structure of the cocoon cooking rotating tank body and the tank cover sealing device, and comprises the following steps:

[0019] 1) When the cocoon cooking is started, the PLC controller sends a signal to the tank body rotating motor, and the tank body starts to rotate forward, from the cocoon adding position to the cocoon cooking position. At this time, the tank body rotating 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 stroke switch, and the positioning stroke switch sends a signal to the PLC controller, and the PLC controller controls the tank body rotating motor to stop running;

[0020] 2) After the cocoons are cooked, the PLC controller sends a cocoon-out signal, and the tank body rotates forward again, from the cocoon-cooking position to the cocoon-out position. The positioning column representing the cocoon-out position contacts the positioning stroke switch, and the positioning stroke switch sends a signal to the PLC controller, and the PLC controller controls the tank body rotation motor to stop running;

[0021] 3) After the cooked cocoons are poured out, the PLC controller sends a signal, the tank body rotation motor starts to run, the tank body reverses, the cocoon discharge position → cocoon cooking position → cocoon adding position, the tank body returns to the cocoon adding position, the positioning column representing the cocoon adding position contacts the positioning stroke switch, and the PLC controller controls the tank body rotation motor to stop running, completing a cocoon cooking cycle.

[0022] The cocoon cooking rotating tank body and tank cover sealing device structure operation method realizes the actuation cooperation between the tank body device and the tank cover based on the cocoon cooking rotating tank body and tank cover sealing device structure, comprising the following steps:

[0023] 1. Sealing between tank cover and tank body:

[0024] 1.1. When the tank is at the cocoon adding position, the tank mouth faces upward and the tank cover is at the upper end of the tank cover track. After the cocoons are added to the tank, the start button is pressed. Driven by the tank body rotating motor, the tank body moves around the tank body rotating axis O1 from the cocoon adding position to the cocoon boiling position and the tank body and the tank cover are sealed;

[0025] 1.2. During the rotation of the tank body, the signal shaft of the tank mouth puller hits the tank cover support plate, pushing the tank cover support plate to rotate around the tank cover support plate rotation axis O2 as the center. The tank cover is separated from the support of the tank cover support plate, falls under the action of gravity and is hung in the tank cover hanging groove by the tank mouth puller, so that the tank cover moves synchronously with the tank body in the tank cover track to the cocoon boiling position;

[0026] 1.3. At the same time, the capping motor starts, driving the capping shaft O3 to rotate 180 degrees. The capping cam is installed on the capping shaft O3, and the can cover and the can body are pressed tightly by the capping cam to achieve the sealing of the can cover and the can body;

[0027] 2. The tank body and the tank cover are separated:

[0028] 2.1. When the cocoon is out, the capping motor starts, driving the capping shaft O3 to rotate 180 degrees, the capping cam is released, and the can cover is separated from the can body;

[0029] 2.2. The tank body is driven by the tank body rotating motor and rotates around the tank body rotating axis O1. Since the tank cover can only move within the tank cover track, the tank cover is separated from the tank body, and the tank body rotates from the cocoon boiling position to the cocoon discharge position, realizing the separation of the tank body and the tank cover;

[0030] 3. Tank body and tank cover return to their original position:

[0031] After the cocoon is finished, the tank body moves in the opposite direction to the cocoon adding position. At this time, the upper edge of the tank mouth flange holds the tank cover connecting plate and moves upward. When the tank cover moves upward, the tank mouth puller extends into the tank cover hanging groove. When the tank body rotates to a certain angle, the tank mouth puller will separate from the tank cover hanging groove. The tank mouth puller holds the tank cover hanging groove to ensure that the tank cover can continue to move upward along the tank cover track until the tank cover supporting plate can hang the guide bearing on the tank cover to realize the return of the tank cover.

[0032] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0033] The present invention improves the existing cocoon boiling tank, forms a cocoon rotating tank body and a tank cover sealing device structure, so that when the tank body rotates from the cocoon adding position to the cocoon boiling position, the tank cover will drive it to fall through the tank cover track, and when the tank body reaches the cocoon boiling position, the tank cover is locked to achieve the sealing of the tank cover and the tank body, and at the same time, the pipeline system is docked and sealed, and the pipeline system connects the vacuum pump, water pump, steam, water supply and drainage with the tank body, generates vacuum in the tank body, and introduces steam and water of different water temperatures to complete the cocoon boiling work such as infiltration, water discharge, boiling, and adjustment protection, so that the sericin swells, puffs, and appropriately dissolves, so as to achieve the purpose of boiling silkworm cocoons. After the cocoons are boiled, the tank body is separated from the tank cover, and the tank body is rotated to the cocoon discharging position to pour out the boiled cocoons, and then the tank body is reversed and returned to the cocoon boiling position to drive the tank cover, return the tank cover, and return the tank body to the cocoon adding position to prepare for the next cocoon boiling.

[0034] The invention is based on the automation and continuity requirements of the cocoon boiling process. By arranging the cocoon boiling rotating tank body and the tank cover sealing device structure, the cocoon boiling rotating tank body can achieve airtightness between the tank body and the tank cover during the rotation process, thereby realizing the technical requirement that the cocoon boiling tank (tank body) is in a sealed state when in the cocoon boiling position.

[0035] In the whole cocoon boiling process, the invention can ensure that the cocoon boiling tank (tank body) and the tank cover always keep in a synchronous state through the design mode that the cocoon boiling tank body drives the tank cover, improve the sealing effect between the tank body and the tank cover, and realize the technical requirement that the cocoon boiling rotating tank is in a sealed state when in the cocoon boiling position.

[0036] The invention can meet the technical requirements of water discharge from the cocoon cavity (upper steam pumping downward or lower steam passing upward) and cooking of the cocoon layer during the cocoon boiling process.

[0037] The present invention adopts PLC control technology to realize the rotation positioning control of the cocoon boiling rotating tank, which can solve the accurate positioning of the tank during the cocoon adding, cocoon boiling and cocoon discharging states. At the same time, the rotation angle of the tank can be more flexibly controlled to realize the automation and continuity of cocoon boiling. BRIEF DESCRIPTION OF THE DRAWINGS

[0087] 1) When the cocoon cooking is started (press the cocoon cooking start button of the control system matched with the PLC controller), the PLC controller sends a signal to the tank body rotating motor, and the tank body starts to rotate forward, from the cocoon adding position to the cocoon cooking position. At this time, the tank body rotating shaft Q12 drives the positioning plate 22 to rotate together. When it rotates to the cocoon cooking position, the positioning column representing the cocoon cooking position (cocoon cooking positioning signal column 24) contacts the positioning stroke switch 21, and the positioning stroke switch 21 sends a signal to the PLC controller, and the PLC controller controls the tank body rotating motor to stop running;

[0088] 2) After the cocoons are cooked, the PLC controller sends a cocoon-out signal, and the tank body 3 rotates forward again, from the cocoon-cooking position to the cocoon-out position, and the positioning column representing the cocoon-out position (cocoon-out positioning signal column 25) contacts the positioning stroke switch 21, and the positioning stroke switch 21 sends a signal to the PLC controller, and the PLC controller controls the tank body rotation motor to stop running;

[0089] 3) After the cooked cocoons are poured out, the PLC controller sends a signal, the tank body rotating motor starts to run, the tank body 3 reverses, the cocoon discharge position → the cocoon cooking position → the cocoon adding position, the tank body 3 returns to the cocoon adding position, the positioning column representing the cocoon adding position (the cocoon adding positioning signal column 23) contacts the positioning stroke switch 21, and the PLC controller controls the tank body rotating motor to stop running, completing a cocoon cooking cycle.

[0090] Embodiment 8:

[0091] This embodiment is further optimized on the basis of any one of the embodiments 1 to 6, and the same points as the above technical solutions are not repeated here. The operation method of the cocoon cooking rotary tank body and the tank cover sealing device structure is based on the cocoon cooking rotary tank body and the tank cover sealing device structure to achieve the actuation coordination between the tank body device and the tank cover. During the cocoon cooking process, the tank body 3 drives the tank cover to run in the tank cover track, combined with Figure 2 As shown, the following steps are included:

[0092] 1. Sealing between tank cover and tank body:

[0093] 1.1. When the tank body 3 is in the cocoon adding position, the tank mouth faces upward and the tank cover is at the upper end of the tank cover track. Figure 4a After adding silkworm cocoons into the tank body 3, the start button is pressed, and the tank body 3, driven by the tank body rotating motor, moves around the tank body rotating axis O12 from the cocoon adding position to the cocoon boiling position and realizes the sealing of the tank body and the tank cover. Figure 4b , Figure 4c As shown;

[0094] 1.2. During the rotation of the tank body 3, the tank mouth puller signal shaft 6 hits the tank cover support plate 15, pushing the tank cover support plate 15 to rotate around the tank cover support plate rotation axis O216 as the center, such as Figure 5a As shown, the can cover is separated from the support of the can cover support plate 15, falls under the action of gravity and is hung in the can cover hanging groove 10 by the can mouth puller 5, so that the can cover moves synchronously with the can body 3 in the can cover track to the cocoon boiling position, as shown in FIG. Figure 5b As shown;

[0095] 1.3. At the same time, the capping motor starts, driving the capping shaft O318 to rotate 180 degrees. The capping cam 19 is installed on the capping shaft O318. The flanges between the tank cover and the tank body 3 (tank mouth flange 4, tank cover flange 11) are pressed by the capping cam 19 to achieve sealing between the tank cover and the tank body 3;

[0096] 2. The tank body 3 is separated from the tank cover:

[0097] 2.1. When the cocoon comes out (press the "Restart / Out" button when the cocoon comes out), the capping motor starts, driving the capping shaft O318 to rotate 180 degrees. Figure 4c , Figure 4d As shown, the capping cam 19 is released, and the can cover is separated from the can body 3;

[0098] 2.2, the tank body 3 is driven by the tank body rotating motor, around the tank body rotating axis O12, because the tank cover can only move in the tank cover track, the tank cover is separated from the tank body 3, and the tank body 3 rotates from the cocoon boiling position to the cocoon discharge position, such as Figure 4d As shown, the tank body 3 is separated from the tank cover;

[0099] 3. Tank body and tank cover return to their original position:

[0100] After the cocoons are produced, the tank 3 moves in the opposite direction to the cocoon adding position. Figure 4e As shown, at this time, the upper edge of the tank mouth flange 4 supports the tank cover connecting plate 8 and moves upward, as shown in FIG. Figure 6 As shown in (a), when the can cover moves upward, the can mouth pull block 5 extends into the can cover hanging groove 10, as shown in FIG. Figure 6 (b) As shown. When the tank body 3 is rotated to a certain angle, the tank mouth pull block 5 will be separated from the tank cover hanging groove 10, as shown in FIG. Figure 6 (c) As shown. The tank mouth pull block 5 holds 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 to realize the return of the tank cover. Figure 6 (d) as shown.

[0101] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
