[0044] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] Two embodiments of the dual-purpose turning machine are described below:

[0046] Example 1

[0047] like Figures 1 to 5 As shown, the dual-purpose turning machine of this embodiment includes: a chassis 10 、 The first turning frame 20, the second turning frame 30, the first driving unit 40, the second driving unit 50, the bottom plate clamping structure 21, and the steaming frame clamping structure 33; the first turning frame 20 is hinged on the bottom frame 10 and is suitable for carrying the unpeeled green body 90; the second turning frame 30 is hinged on the bottom frame 10, and the second turning frame 30 is provided with a movable frame 35 and a movable driving unit 36. The movable frame 35 is suitable for carrying the turned green body 90, and the movable driving unit 36 ​​drives the movable frame 35 to move; the first driving unit 40 is hinged to the first turning frame 20 and the second turning frame 30 respectively, and the first driving unit 40 drives the second turning frame 30 to turn over; the second driving unit 50 is hinged to the bottom frame 10 and the first turning frame 20 respectively, and the second driving unit 50 drives the first turning frame 20 to turn over; the bottom plate clamping structure 21 is provided on the first turning frame 20, and the bottom plate clamping structure 21 has a first clamping state for clamping the bottom plate 91 and a first loosening state for loosening the bottom plate 91. The steaming frame clamping structure 33 is disposed on the movable frame 35 . The steaming frame clamping structure 33 has a second clamping state for clamping the steaming frame 80 and a second loosening state for loosening the steaming frame 80 .

[0048] When the dual-purpose turning machine of this embodiment is used, the green body 90 without the bottom skin removed is placed on the first turning frame 20 during the cross-cutting vertical steaming process, the first driving unit 40 drives the second turning frame 30 to turn 90° counterclockwise to fit closely to the green body 90, the second driving unit 50 drives the first turning frame 20 and the second turning frame 30 to turn 90° clockwise together, and the second driving unit 50 drives the first turning frame 20 to turn 90° counterclockwise alone to separate the bottom skin, that is, to complete the turning of the green body 90; when the cross-cutting horizontal steaming process is used, the green body 90 without the bottom skin removed is placed on the first turning frame 20, the first driving unit 40 drives the second turning frame 30 to turn 90° counterclockwise to fit closely to the green body 90, and the second driving unit 50 drives The first turning frame 20 and the second turning frame 30 turn clockwise by 90° together, and the second driving unit 50 drives the first turning frame 20 to rotate counterclockwise by 90° alone to achieve bottom skin separation. The second driving unit 50 drives the first turning frame 20 to rotate clockwise by 90° alone again, and the moving frame 35 moves close to the first turning frame 20. After the blank 90 is fitted with the first turning frame 20, the second driving unit 50 drives the first turning frame 20 and the second turning frame 30 to turn counterclockwise by 90° together, thus completing the turning of the blank 90. ​​This effectively solves the problems of poor replaceability and single function of the turning machine in the prior art, so that the same turning machine can be applied to both horizontal steaming and vertical steaming process production, realizing dual use of one machine.

[0049] Among them, Figure 1 As shown, the second turning frame 30 turns counterclockwise when approaching the first turning frame 20, and the first turning frame 20 turns clockwise when approaching the second turning frame. The blank 90 without the bottom skin removed refers to the blank whose bottom skin has been cut but not separated.

[0050] Specifically, the specific layout of the base frame 10 can be freely selected, as long as it can stably support the first and second turning frames 20 and 30. The first and second turning frames 20 and 30 are coaxially hinged on the base frame 10 and are initially in a horizontal position. The specific structure of the first and second turning frames 20 and 30 can be selected according to actual processing requirements, as long as they can stably support the blank. The first and second driving parts 40 and 50 are preferably hydraulic cylinders, which have a stronger load-bearing capacity and a smoother movement process. The initial state of the first driving part 40 is a retracted state, and the initial state of the second driving part 50 is an extended state. It is understood that as an alternative embodiment, the first and second turning frames 20 and 30 can also be coaxially hinged, and the first and second driving parts 40 and 50 can also be other driving parts such as electric cylinders and pneumatic cylinders. The initial states of the first and second driving parts 40 and 50 can be changed as needed.

[0051] In this embodiment, the bottom plate clamping structure 21 is fixedly mounted on the first turning frame 20. After the blank 90 with the bottom skin is delivered to the first turning frame 20, the bottom plate clamping structure 21 clamps the bottom plate 91 below the blank 90. ​​After the blank 90 is turned 90°, the bottom plate 91 with the bottom skin is separated from the blank 90 as the first turning frame 20 turns counterclockwise, thereby better separating the bottom plate 91 with the bottom skin from the blank 90. ​​It is understood that the bottom plate clamping structure 21 may also be omitted. After the blank 90 is turned, the first turning frame 20 directly turns counterclockwise, and the bottom plate 91 with the bottom skin falls off directly.

[0052] In this embodiment, the bottom plate clamping structure 21 includes a plurality of first clamping jaws 211 provided on one side and a second driving member 212 cooperating with the plurality of first clamping jaws 211. The portion between the two ends of each first clamping jaw 211 is hinged to the second driving member 212. One end of each first clamping jaw 211 is hinged to the first flip frame 20 and the other end is suitable for clamping the bottom plate 91. The second driving member 212 drives the first clamping jaw 211 to swing to clamp the bottom plate 91. Figure 10 As shown, the bottom plate clamping structure 21 further includes a fixed plate 213 disposed on the other side. The top of the fixed plate 213 has a groove for accommodating the bottom plate 91. After the blank 90 with the bottom skin is delivered to the first turning frame 20, one side of the bottom plate 91 is clamped in the groove of the fixed plate 213, and the multiple first clamping jaws 211 on the other side are lifted to clamp the other side of the bottom plate 91, thereby clamping the bottom plate 91. The second driving member 212 is an oil cylinder, a pneumatic cylinder, or an electric cylinder.

[0053] In this embodiment, the steaming frame clamping structure 33 includes a plurality of second clamping jaws 331 and a third driving member 332 that cooperates with the plurality of second clamping jaws 331. The portion between the ends of each second clamping jaw 331 is hingedly connected to the second turning frame 30. The lower end of each second clamping jaw 331 is hingedly connected to the third driving member 332. The third driving member 332 drives the second clamping jaws 331 to swing, thereby clamping the steaming frame 80. This simple structure occupies little space. During the horizontal cutting and vertical steaming process, the steaming frame 80 is placed on the second turning frame 30. The steaming frame clamping structure 33 clamps the steaming frame 80 to prevent it from swinging. After the blank 90 is flipped 90° and falls onto the steaming frame 80, the steaming frame clamping structure 33 is released, and the blank 90 and the steaming frame 80 are lifted away by a crane, effectively accelerating the turning process. Preferably, the third driving member 332 is a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0054] In this embodiment, a load-bearing frame 31 and a lifting drive structure 32 are provided on the movable frame 35. The load-bearing frame 31 is suitable for carrying the blank. The lifting drive structure 32 cooperates with the load-bearing frame 31. The load-bearing frame 31 has a load-bearing position higher than the steaming frame 80 and a avoidance position lower than the steaming frame 80. When the blank 90 is flipped onto the load-bearing frame 31, the lifting drive structure 32 drives the load-bearing frame 31 to descend so that the blank 90 falls onto the steaming frame 80, so that the blank 90 can directly enter the steaming link without the need to use an additional crane to place the blank 90 on the steaming frame 80.

[0055] Specifically, the steaming frame 80 includes a frame body and a plurality of spaced support plates, and the supporting rack 31 includes a plurality of spaced support plates, and the plurality of support plates are interspersed in the plurality of supporting plates corresponding to the supporting racks 31 .

[0056] In this embodiment, the movable frame 35 is further provided with a steaming frame conveying mechanism 34. The steaming frame conveying mechanism 34 is adapted to convey a steaming frame 80. After the steaming frame 80 containing the blanks 90 is hoisted away, a new steaming frame is fed into the turning machine via the steaming frame conveying mechanism 34. This automatically feeds the steaming frames 80, eliminating the need for a crane to bring them in. It is understood that, as an alternative embodiment, the steaming frame conveying mechanism 34 may be omitted, and the steaming frame 80 may be hoisted onto the second turning frame 30 by a crane.

[0057] Specifically, the steaming frame conveying mechanism 34 includes a plurality of second drive wheels 341 and a plurality of second guide wheels 342. The plurality of second drive wheels 341 and the plurality of second guide wheels 342 are disposed on the second turning frame 30 to carry the steaming frame 80. After the steaming frame clamping structure 33 is unlocked, the plurality of second drive wheels 341 drive the steaming frame 80 to flow into the second turning frame 30 along the direction set by the plurality of second guide wheels 342. It is understood that the steaming frame conveying mechanism 34 may also be a chain conveying mechanism, a belt conveying mechanism, or other conveying mechanism that can stably carry and convey the steaming frame 80.

[0058] In this embodiment, a bottom skin clamping structure 24 is also provided on the first turning frame 20. The bottom skin clamping structure 24 has a third clamping state for clamping the bottom skin and a third loosening state for loosening the bottom skin. After the blank 90 with the bottom skin is sent to the first turning frame 20, the bottom skin clamping structure 24 clamps the bottom skin under the blank 90. ​​After the blank 90 is turned 90°, the bottom plate 91 with the bottom skin is separated from the blank 90 as the first turning frame 20 is turned counterclockwise, so that the bottom skin will not fall off during the separation process, and at the same time, the bottom plate 91 with the bottom skin can be better separated from the blank 90 to prevent the bottom skin from falling on the work station where the turning machine is located.

[0059] In this embodiment, the bottom skin clamping structure 24 includes a plurality of third clamping jaws 241 and a fourth driving member 242 that cooperates with the plurality of third clamping jaws 241. The portion between the ends of each third clamping jaw 241 is hingedly connected to the fourth driving member 242. One end of each third clamping jaw 241 is hingedly connected to the first tilting frame 20, and the other end is adapted to clamp the bottom plate 91. The fourth driving member 242 drives the third clamping jaws 241 to swing, thereby clamping the bottom skin. This structure is simple and easy to install. The fourth driving member 242 can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0060] Specifically, multiple third clamping jaws 241 are disposed on both sides of the bottom plate 91. The bottom skin clamping structure 24 also includes multiple pressure plates 243. At least one third clamping jaw 241 located on the same side is connected to a pressure plate 243. Each pressure plate 243 is disposed at the clamping end of at least one third clamping jaw 241 on the corresponding side. The multiple third clamping jaws 241 located on both sides of the bottom plate 91 swing together, so that the pressure plates 243 on both sides simultaneously press the bottom skin. When each third clamping jaw 241 is released, it swings away from the bottom plate 91. It is understood that the pressure plates 243 may not be provided, and each third clamping jaw 241 may press on the bottom skin independently.

[0061] In this embodiment, the first turning frame 20 is further provided with a bottom plate conveying mechanism 22. The bottom plate conveying mechanism 22 is adapted to convey bottom plates 91 to replace bottom plates 91. After the first turning frame 20 is independently turned counterclockwise by 90°, the bottom plate clamping structure 21 is unlocked, and the bottom plate conveying mechanism 22 allows the bottom plates 91 with the bottom skin to flow out of the turning frame without requiring additional crane operation. During the cross-cutting and cross-steaming process, after the bottom plates 91 with the bottom skin automatically flow out, new bottom plates 91 can automatically flow in, achieving automatic outflow and inflow of bottom plates 91. It is understood that, as an alternative embodiment, the bottom plate conveying mechanism 22 may also be omitted, and the bottom plates 91 with the bottom skin may be lifted away by a crane.

[0062] Specifically, the bottom plate conveying mechanism 22 includes a plurality of first drive wheels 221 and a plurality of first guide wheels 222. The plurality of first drive wheels 221 and the plurality of first guide wheels 222 are arranged on the bottom plate conveying mechanism 22 to carry the bottom plate 91. After the bottom plate clamping structure 21 is unlocked, the first drive wheels 221 drive the bottom plate 91 to flow out of the turning table in the direction set by the plurality of first guide wheels 222. It is understood that the bottom plate conveying mechanism 22 can also be a chain conveying mechanism, a belt conveying mechanism, or other forms, as long as it can stably carry and convey the bottom plate 91.

[0063] In this embodiment, after the base plate 91 with the bottom cover automatically flows out, a new base plate 91 flows in. The new base plate 91 is specially made and suitable for direct steam curing, which can prevent the base plate 91 from deforming during steam curing and causing cracking of the green body. It is understood that after the base plate 91 with the bottom cover automatically flows out, it can also flow into a steam curing frame of corresponding size.

[0064] In this embodiment, the dual-purpose turning machine also includes a conveying part 60, which cooperates with the first turning frame 20. The conveying part 60 has a loading position away from the rotation axis of the first turning frame 20 and a turning position close to the rotation axis. The conveying part 60 is suitable for conveying the blanks 90 from the loading position to the turning position. The crane delivers the first stack of blanks 90 to the loading position of the conveying part 60, and the conveying part 60 conveys the blanks 90 to the turning position. After the blanks 90 are peeled, they wait to be lifted away. At this time, the crane first lifts the next stack of blanks 90 to the loading position of the conveying part 60, and then lifts away the blanks 90 with the bottom skin removed. At this time, the next stack of blanks 90 can be conveyed immediately. The first turning frame 20 and the second turning frame 30 are independently flipped, so that some processes of the first turning frame 20 and the second turning frame 30 can be carried out simultaneously, the production rhythm is faster, the production efficiency is improved, and the flipping rhythm of the bottom peeling process is more compact.

[0065] Specifically, when the base plate clamping structure 21 is in the first loosened state and the conveying portion 60 is conveying the blank, the position of each component of the base plate clamping structure 21 is lower than the conveying plane of the conveying portion 60 to prevent the components of the base plate clamping structure 21 from interfering with the blank 90.

[0066] In this embodiment, the turning machine also includes a lifting frame 70, a lifting drive unit and a fixed frame 72. The conveying unit 60 is fixedly arranged on the lifting frame 70, and the lifting frame 70 can be lifted and lowered on the fixed frame 72. The lifting drive unit cooperates with the lifting frame 70 to drive the lifting frame 70 to move up and down. After the conveying unit 60 conveys the blank 90 to the turning position, the lifting frame 70 descends until it is lower than the upper surface of the first turning frame 20, so that the blank 90 falls on the first turning frame 20. The up and down movement and conveying process of the conveying unit 60 are independently controlled. After the conveying unit 60 descends, it will not interfere with the movement of the first turning frame 20, making the conveying process more reliable. At the same time, when the first turning frame 20 is working, it can independently start pre-conveyance of the next stack of blanks.

[0067] Specifically, the lifting frame 70 is a frame structure. The specific structure of the lifting frame 70 can be changed according to the use process. It only needs to be able to carry the conveying part 60 and complete the lifting. The lifting drive part can be a motor or a cylinder, which can drive the lifting frame 70 smoothly.

[0068] In this embodiment, the turning machine also includes a first synchronization mechanism 71, which is respectively connected to the lifting frame 70 and the fixed frame 72 to drive the lifting frame 70 to rise and fall smoothly. The first synchronization mechanism 71 enables the lifting frame 70 to remain horizontal during the rising and falling process to prevent the blank 90 from tilting and overturning.

[0069] In this embodiment, the first synchronization mechanism 71 includes two first synchronization gears 711 and two first racks 712 that are meshed in a one-to-one manner. The two first synchronization gears 711 rotate synchronously and are set on the lifting frame 70, and the two first racks 712 are set on the fixed frame 72. Alternatively, the two first synchronization gears 711 rotate synchronously and are set on the fixed frame 72, and the two first racks 712 are set on the lifting frame 70. The gear and rack transmission is stable, reliable, and easy to manufacture.

[0070] Specifically, the fixed frame 72 is an independent bracket, and the fixed frame 72 has four legs 11. The lifting frame 70 cooperates with the four legs 11 of the fixed frame 72. The first synchronization mechanism 71 is not set between the two legs 11 where the rotation axes of the first flip frame 20 and the second flip frame 30 are located to prevent the first synchronization mechanism 71 from hindering the movement of other moving parts. A group of first synchronization mechanisms 71 is set between each adjacent two legs 11, so that the three sides of the lifting frame 70 are transmitted by the first synchronization mechanism 71, and the two first synchronization gears 711 in each first synchronization mechanism 71 are connected by a synchronization rod 713.

[0071] Preferably, the lifting drive unit includes multiple small drive cylinders mounted on the support legs 11. The cylinder barrel of each small drive cylinder is mounted on the support legs 11, and the piston rod of each small drive cylinder is fixedly connected to the synchronization rod 713. To ensure continuous and smooth ascent or descent, the multiple small drive cylinders are symmetrically arranged on the fixed frame 72 to ensure that the driving force they provide is evenly distributed on the lifting frame 70. It is understood that as an alternative embodiment, the lifting drive unit can adopt a rack and pinion mechanism, etc.

[0072] It can be understood that the specific form of the first synchronization mechanism 71 can be changed according to needs, the arrangement and number of the first synchronization mechanism 71 can be adjusted according to the processing process, the lifting drive part can also be a separate drive component, the setting position of the lifting drive part can also be the ground, or a mounting frame for the lifting drive part can be set separately, or the first synchronization mechanism 71 can be not set, and the lifting drive part directly drives the lifting frame 70 to move.

[0073] In this embodiment, the conveying unit 60 includes a first driving member 65, a plurality of spaced apart conveying chains 61, and a driving sprocket 62 and a driven sprocket 63 meshed with each conveying chain 61. The first driving member 65 drives the driving sprocket 62 to rotate. The chain and sprocket conveying structure has a stronger load-bearing capacity and a more stable conveying process. Preferably, the first driving member 65 is a reduction motor or the like.

[0074] In this embodiment, multiple conveyor chains 61 are arranged on both sides of the first turning frame 20, and the minimum spacing between the conveyor chains 61 on both sides of the first turning frame 20 is greater than the length of the first turning frame 20. When the conveying part 60 descends, the blank 90 can fall on the first turning frame 20, so that the first turning frame 20 can rotate independently, avoiding interference between the first turning frame 20 and the conveyor chain 61 when turning over.

[0075] Specifically, the number of multiple conveyor chains 61 is preferably two conveyor chains 61 and they are arranged on both sides of the first turning frame 20. The driving sprocket 62 of each conveyor chain 61 is arranged at one end of the lifting frame 70 away from the first turning frame 20. The two driving sprockets 62 are coaxially driven through the rotating shaft 64. The first driving member 65 is arranged on the lifting frame 70 and connected to the rotating shaft 64. The first driving member 65 drives the rotating shaft 64 to rotate. The top of the first driving member 65 is lower than the conveying plane of the conveying chain 61 to prevent the first driving member 65 from hitting the bottom plate 91 during conveying. The specific setting position of the first driving member 65 can be changed. If the first driving member 65 and the rotating shaft 64 are not set on the same axis, a cross-joint universal coupling can be used for connection.

[0076] In this embodiment, the turning machine also includes a second synchronization mechanism 37, which is connected to the supporting frame 31 and the second turning frame 30 respectively. The second synchronization mechanism 37 allows the supporting frame 31 to remain horizontal during the lifting process to prevent the blank from tilting and overturning.

[0077] Specifically, the second synchronization mechanism 37 includes two second synchronization gears 371 and two second racks 372 that are meshed in one-to-one correspondence. The two second synchronization gears 371 rotate synchronously and are set on the supporting frame 31, and the two second racks 372 are set on the second flip frame 30. Alternatively, the two second synchronization gears 371 rotate synchronously and are set on the second flip frame 30, and the two second racks 372 are set on the supporting frame 31. The gear and rack transmission is smooth, reliable and easy to manufacture.

[0078] Preferably, the lifting drive structure 32 further includes a plurality of symmetrically arranged small drive cylinders, the specific location of which can be selected according to needs, as long as they can stably drive the carrier 31 to move up and down. It is understood that as an alternative embodiment, the lifting drive structure 32 adopts a gear rack mechanism, etc.

[0079] It can be understood that the specific form of the lifting drive structure 32 can be changed according to needs, and the arrangement and number of the second synchronization gear 371 and the second rack 372 can be adjusted according to the processing process.

[0080] In this embodiment, the dual-purpose turning machine further includes a guide mechanism disposed between the mobile frame 35 and the second turning frame 30. The guide mechanism guides the movement of the mobile frame 35, thereby ensuring smoother movement of the mobile frame 35. Specifically, the guide mechanism includes a guide rail 351 and a slider 352. The slider 352 slides on the guide rail 351. The slider 352 is disposed on the mobile frame 35, and the guide rail 351 is disposed on the second turning frame 30. This allows the second turning frame 30 to better support the mobile frame 35 and makes the translation process more stable and reliable.

[0081] In this embodiment, the dual-purpose turning machine further includes a third synchronization mechanism, which cooperates with the mobile frame 35 and the second turning frame 30, respectively. This third synchronization mechanism maintains the horizontal position of the carrier frame 31 during movement, making the translation of the mobile frame 35 more stable and reliable. Specifically, the third synchronization mechanism includes a third synchronization gear 353 and a third rack 354. The third rack 354 meshes with the third synchronization gear 353, causing the third rack 354 to move horizontally. The third rack 354 is mounted on the mobile frame 35, and the third synchronization gear 353 is rotatably mounted on the second turning frame 30. This rack and pinion transmission is stable, reliable, and easy to manufacture.

[0082] Specifically, a guide rail 351 is provided on each of the left and right sides of the upper surface of the second flip frame 30. A plurality of sliders 352 are provided at corresponding positions on the lower surface of the movable frame 35. The movable drive unit 36 ​​includes two drive cylinders symmetrically arranged on the lower surface of the movable frame 35, located between the two guide rails 351. The fixed end of each drive cylinder is fixed to the movable frame 35, and the movable end of each drive cylinder is connected to the second flip frame 30. Two third synchronization gears 353 are provided below the corresponding positions of the two drive cylinders of the movable drive unit 36 ​​and are connected via a synchronization shaft. Two third racks 354 are provided on the lower surfaces of the two drive cylinders of the movable drive unit 36. It will be understood that as an alternative embodiment, the connection method between the movable frame 35 and the second flip frame 30 can be changed according to the manufacturing process. It can be connected entirely by guide rails and sliders, or entirely by gears and racks. The setting positions of the guide rails 351 and the sliders 352 can be changed, the corresponding positions of the third synchronization gears 353 and the third racks 354 can also be changed, and the movable drive unit 36 ​​can also adopt other drive structures.

[0083] The following describes how to use the flip machine of this embodiment:

[0084] Cross-cutting vertical steaming process: The first turning frame 20 and the second turning frame 30 are both in a horizontal position, and the conveying section 60 is now in a higher horizontal position than the first turning frame 20. The crane hoists the cut, but unpeeled, green body 90 into the loading position of the conveying section 60, which then horizontally conveys the green body 90 to the turning position. The lifting frame 70 descends, allowing the green body 90 to land on the steaming frame conveying mechanism 34. The bottom plate clamping structure 21 clamps the bottom plate 91 of the green body 90, and the bottom skin clamping structure 24 clamps the bottom skin of the green body 90. The piston rod of the first driving part 40 extends to drive the second turning frame 30 to turn counterclockwise by 90 degrees so that the carrier 31 fits the blank 90; the first driving part 40 is locked, and the first turning frame 20 and the second turning frame 30 rotate together; the piston rod of the second driving part 50 retracts to drive the first turning frame 20 and the second turning frame 30 to rotate clockwise by 90 degrees at the same time, and the blank 90 falls on the carrier 31; the lifting driving structure 32 drives the carrier 31 to descend, and the blank 90 falls on the steaming frame 80. The carrier 31 descends to below the conveying surface of the steaming frame conveying mechanism 34, the steaming frame clamping structure 33 releases the steaming frame 80, and at the same time the piston rod of the first driving unit 40 retracts to drive the first turning frame 20 to turn the bottom plate 91 and the bottom skin 90 degrees counterclockwise back to the horizontal position, the bottom plate clamping structure 21 releases the bottom plate 91, the bottom skin clamping structure 24 releases the bottom skin, the bottom plate conveying mechanism 22 moves the bottom plate 91 with the bottom skin out of the first turning frame 20, the lifting frame 70 rises, and the crane hoists the next stack of blanks 90 into the bottom plate. When the conveyor 60 reaches the loading position, the conveyor 60 starts conveying, and then the crane lifts the blanks 90 that have fallen on the steaming frame 80 together with the steaming frame 80; when the conveyor 60 conveys the next batch of blanks 90 to the turning position, the steaming frame conveying mechanism 34 inputs a new steaming frame 80; after the steaming frame clamping structure 33 clamps the new steaming frame 80, the next batch of blanks 90 arrives at the turning position, the conveyor 60 descends and the carrier 31 ascends; then the next batch of blanks 90 is turned over.

[0085] Cross-cutting and cross-steaming process: The first turning frame 20 and the second turning frame 30 are both in a horizontal position, and the horizontal position of the conveying part 60 is higher than the first turning frame 20; the crane hoists the cut green body 90 without the bottom skin removed into the loading position of the conveying part 60, and the conveying part 60 horizontally conveys the green body 90 to the turning position; the lifting frame 70 descends, so that the green body 90 falls on the steaming frame conveying mechanism 34, the bottom plate clamping structure 21 clamps the bottom plate 91 of the green body 90, and the bottom skin clamping structure 24 clamps the bottom skin of the green body 90 The piston rod of the first driving part 40 extends to drive the second turning frame 30 to turn counterclockwise by 90 degrees so that the carrier 31 fits the blank 90; the first driving part 40 is locked, and the first turning frame 20 and the second turning frame 30 rotate together; the piston rod of the second driving part 50 retracts to drive the first turning frame 20 and the second turning frame 30 to rotate clockwise by 90 degrees at the same time, and the blank 90 falls on the carrier 31; the piston rod of the first driving part 40 retracts to drive the first turning frame 20 with the bottom plate 91 and the bottom skin sheet The first turning frame 20 is turned counterclockwise by 90° and returns to the horizontal position. The bottom plate clamping structure 21 releases the bottom plate 91, and the bottom skin clamping structure 24 releases the bottom skin. The bottom plate conveying mechanism 22 flows the bottom plate 91 with the bottom skin out of the first turning frame 20 and flows the new bottom plate 91 in. The bottom plate clamping structure 21 clamps the new bottom plate 91. The piston rod of the first driving unit 40 extends to drive the first turning frame 20 to turn clockwise by 90° alone. At the same time, the mobile driving unit 36 ​​drives the mobile frame 35 to approach the first turning frame 20 so that the blank 90 is close to the first turning frame 20. A new bottom plate 91; the piston rod of the second driving part 50 retracts to drive the first turning frame 20 and the second turning frame 30 to turn counterclockwise 90° together; the piston rod of the first driving part 40 retracts to drive the second turning frame 30 to turn clockwise 90° alone to return to its original position, and the crane lifts the next stack of blanks 90 to the conveying position of the conveying part 60 to start conveying, and then lifts away the blanks 90 with the bottom skin removed at this time; after the conveying part 60 rises and sends the next stack of blanks 90 to the turning position, the next blank 90 starts to be turned.

[0086] Example 2

[0087] like Figures 6 to 12 As shown, the difference between the turning machine of Example 2 and Example 1 lies in whether the conveying part 60 turns over together with the first turning frame 20. In Example 2, the lifting frame 70 and the lifting drive part are not provided on the turning machine, and the conveying part 60 is directly fixed on the first turning frame 20.

[0088] Specifically, after the blank 90 is transported to the flipping position by the conveying part 60, the bottom plate clamping structure 21 directly clamps the bottom plate 91 of the blank 90. ​​The conveying part 60 carries the blank 90 and flips it together with the first flipping frame 20. The conveying surface of the conveying part 60 is higher than the conveying surface of the bottom plate conveying mechanism 22 to ensure the normal load of the blank 90.

[0089] In this embodiment, a lifting structure 23 is also provided on the first turning frame 20. The lifting structure 23 cooperates with the bottom plate conveying mechanism 22 on the first turning frame 20 to drive the bottom plate conveying mechanism 22 to rise and fall. After the bottom plate 91 with the bottom skin is flipped 90° counterclockwise with the first turning frame 20, the bottom plate clamping structure 21 is released, and the lifting structure 23 drives the bottom plate conveying mechanism 22 to rise until the conveying surface of the bottom plate conveying mechanism 22 is higher than the conveying surface of the conveying part 60 and carries the bottom plate 91. Then, the bottom plate 91 flows out of the turning machine through the bottom plate conveying mechanism 22, realizing the automatic outflow of the bottom plate 91. After the bottom plate 91 flows out, the lifting structure 23 drives the bottom plate conveying mechanism 22 to descend and return to its original position.

[0090] Specifically, the jacking structure 23 includes a plurality of jacking plates 231 and a plurality of jacking drive cylinders 232. The plurality of first guide wheels 222 are arranged in pairs, with each pair of first guide wheels 222 correspondingly disposed on the upper surface of a jacking plate 231. Each jacking drive cylinder 232 is disposed below the corresponding jacking plate 231, and the movable end of each jacking drive cylinder 232 is connected to the jacking plate 231. It is understood that, as an alternative embodiment, the jacking structure 23 can also be a larger jacking plate that carries all the first guide wheels 222, and the jacking drive cylinder 232 can also be other forms of drive components, as long as they can drive the larger jacking plate to rise and fall.

[0091] Four embodiments of the blank circulation method are described below:

[0092] Example 1

[0093] The green body 90 with the bottom skin not removed is placed on the first turning frame 20; the bottom plate 91 is clamped by the bottom plate clamping structure 21; the steaming frame 80 is placed on the second turning frame 30; the steaming frame 80 is clamped by the steaming frame clamping structure; the second turning frame 30 is driven by the first driving unit 40 to turn 90° counterclockwise; the first turning frame 20 and the second turning frame 30 are driven by the second driving unit 50 to turn 90° clockwise together; the first turning frame 20 is driven by the second driving unit 50 to turn 90° away from the second turning frame 30 to separate the bottom skin; the steaming frame 80 is released by the steaming frame clamping structure; and the steaming frame 80 on the second turning frame 30 together with the green body 90 is transported out.

[0094] The green body circulation method is applicable to the cross-cutting vertical steaming process and uses the turnover machine of the above-mentioned embodiment 1. The green body circulation method is applicable to the ALC production line.

[0095] In this embodiment, during the step of placing the unpeeled bottom-skinned blank 90 on the first turning frame 20, the bottom plate 91 and the unpeeled bottom-skinned blank 90 thereon are placed on the first turning frame 20. After placing the unpeeled bottom-skinned blank 90 on the first turning frame 20, the step further includes: clamping the bottom skin by the bottom skin clamping structure 24. During the turning process, the bottom plate clamping structure 21 holds the bottom plate 91 and the bottom skin together to prevent the bottom skin from falling off.

[0096] In this embodiment, while the steaming frame 80 on the second turning frame 30 is being transferred out together with the blank 90, the bottom plate 91 is loosened by the bottom plate clamping structure 21, the bottom skin is loosened by the bottom skin clamping structure 24, and the bottom plate 91 with the bottom skin is conveyed out by the bottom plate conveying mechanism 22, so as to realize the bottom SY223053CN.

[0097] Automatic outflow of plate 91.

[0098] In this embodiment, in the step of placing the unpeeled green body 90 on the first turning frame 20, the green body is placed on the loading position of the conveyor 60, and the green body 90 is conveyed from the loading position to the turning position by the conveyor 60. Loading by the conveyor 60 speeds up the loading and unloading cycle and improves production efficiency.

The upward and downward movement of the conveyor 60 and the conveying process are independently controlled. After the conveyor 60 descends, it does not interfere with the movement of the first turning frame 20, making the conveying process more reliable. At the same time, while the first turning frame 20 is operating, it can independently begin pre-conveying the next batch of blanks.

[0100] In this embodiment, after the step of clamping the steaming frame 80 by the steaming frame clamping structure, the step further includes: driving the supporting frame 31 to rise above the steaming frame 80 by the lifting drive structure 32; and before the step of releasing the steaming frame 80 by the steaming frame clamping structure 33, the step further includes: driving the supporting frame 31 to descend by the lifting drive structure 32 so that the blank 90 falls on the steaming frame 80. There is no need to use an additional crane to place the blank 90 on the steaming frame 80.

[0101] In this embodiment, in the step of placing the steaming frame 80 on the second turning frame 30 , the steaming frame 80 is conveyed in by the steaming frame conveying mechanism, so that the steaming frame 80 can be automatically fed in without the need for a crane.

[0102] Example 2

[0103] The blank circulation method of Example 2 uses the turning machine of Example 2 mentioned above. Most of the steps of the blank circulation method of Example 2 are the same as those of Example 1, except that: while transferring the blank 90 on the second turning rack 30, the bottom plate conveying mechanism 22 is lifted to a level above the conveying part 60 by the lifting structure 23, the bottom plate 91 with the bottom skin is conveyed out by the bottom plate conveying mechanism 22, and the bottom plate conveying mechanism 22 is lowered to a level below the conveying part 60 by the lifting structure 23.

[0104] Example 3

[0105] The blank circulation method of this embodiment includes the following steps:

[0106] The unpeeled base body 90 is placed on the first turning frame 20; the bottom plate 91 is clamped by the bottom plate clamping structure 21; the steaming frame 80 is placed on the second turning frame 30; the steaming frame 80 is clamped by the steaming frame clamping structure; the second turning frame 30 is driven by the first driving unit 40 to turn 90° toward the first turning frame 20; the first turning frame 20 and the second turning frame 30 are driven by the second driving unit 50 to turn 90° counterclockwise together; the first turning frame 20 is driven by the second driving unit 50 to turn 90° away from the second turning frame 30 to separate the base skin; the steaming frame 80 is released by the steaming frame clamping structure; the bottom plate clamping structure 21 is used to clamp the steaming frame 80 ... Loosen the bottom plate 91; transport the bottom plate 91 with the bottom skin out, and transport the new bottom plate 91 to the first turning frame 20; clamp the new bottom plate 91 by the bottom plate clamping structure 21; drive the movable frame 35 to move a preset distance toward the first turning frame 20 by the movable driving part on the second turning frame 30; drive the first turning frame 20 to turn 90° toward the second turning frame 30 by the second driving part 50; drive the first turning frame 20 and the second turning frame 30 to turn 90° in the opposite direction together by the second driving part 50; loosen the new bottom plate 91 by the bottom plate clamping structure 21; transport the new bottom plate 91 on the first turning frame 20 together with the blank 90.

[0107] The green body circulation method is applicable to the cross-cutting and cross-steaming process and uses the turning machine of the above-mentioned embodiment 1.

[0108] The steps of the blank circulation method of the third embodiment are the same as those of the blank circulation method of the first embodiment, and are no longer SY223053CN.

[0109] Describe in detail.

[0110] In this embodiment, after the bottom plate 91 with the bottom skin is transported out, the new bottom plate 91 is transported to the first flip rack 20, the bottom plate 91 with the bottom skin is transported out through the bottom plate conveying mechanism 22, and the new bottom plate 91 is transported in through the bottom plate conveying mechanism 22, and the new bottom plate 91 is clamped by the bottom plate clamping structure 21, thereby realizing the automatic outflow and inflow of the bottom plate 91.

[0111] Example 4

[0112] The blank circulation method of Example 4 uses the turning machine of Example 2 above. Most of the steps of the blank circulation method of Example 4 are the same as those of Example 3, except that: while the moving drive unit on the second turning frame 30 drives the movable frame 35 to move a preset distance toward the first turning frame 20, the bottom plate conveying mechanism 22 is lifted to a level above the conveying portion 60 by the lifting structure 23, the bottom with the bottom skin is conveyed out by the bottom plate conveying mechanism 22, a new bottom plate 91 is conveyed in by the bottom plate conveying mechanism 22, the bottom plate conveying mechanism 22 is lowered to a level below the conveying portion 60 by the lifting structure 23, and the new bottom plate 91 is clamped by the bottom plate clamping structure 21.

[0113] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0114] 1. A first turning frame 20 and a second turning frame 30 that can be turned over independently are provided on the base frame 10, a movable moving frame 35 is provided on the second turning frame 30, a bottom plate clamping structure 21 is provided on the first turning frame 20, and a steaming frame clamping structure 33 is provided on the movable frame 35. Through the cooperation of the first turning frame 20, the second turning frame 30, the movable frame 35, the bottom plate clamping structure 21 and the steaming frame clamping structure 33, the turning of the cross-cutting and horizontal steaming process and the turning of the cross-cutting and vertical steaming process are simultaneously achieved, so that the same turning machine can achieve two turning modes.

[0115] 2. A bottom skin clamping structure 24 is also provided on the first turning frame 20. The bottom skin clamping structure 24 has a third clamping state for clamping the bottom skin and a third loosening state for loosening the bottom skin. After the blank 90 is turned 90°, the bottom plate 91 with the bottom skin is separated from the blank 90 as the first turning frame 20 is turned counterclockwise, so that the bottom skin will not fall off during the separation process. At the same time, the bottom plate 91 with the bottom skin can be better separated from the blank 90 to prevent the bottom skin from falling onto the work station where the turning machine is located.

[0116] 3. A bottom plate conveying mechanism 22 is provided on the first turning frame 20. The bottom plate conveying mechanism 22 is suitable for conveying the bottom plate 91 to replace the bottom plate 91. In the cross-cutting and cross-steaming process, after the bottom plate 91 with the bottom skin automatically flows out, the new bottom plate 91 can automatically flow in, realizing the automatic outflow and inflow of the bottom plate 91.

[0117] 4. A conveying portion 60 is provided on the dual-purpose turning machine. The conveying portion 60 cooperates with the first turning frame 20. The conveying portion 60 is suitable for conveying the green body 90 from the loading position to the turning position. In the cross-cutting and vertical steaming process, when the green body 90 located on the second turning frame 30 is lifted away, the next stack of green bodies 90 enters the turning position at the same time, and the next stack of green bodies 90 can be turned immediately, making the turning rhythm of the cross-cutting and horizontal steaming process more compact.

[0118] 5. A steaming frame conveying mechanism 34 is further provided on the movable frame 35. The steaming frame conveying mechanism 34 is suitable for conveying the steaming frame 80. After the steaming frame 80 with the blanks 90 is lifted away, a new steaming frame flows in through the steaming frame conveying mechanism 34, realizing the automatic inflow of the steaming frame 80 without the need for a crane to bring it in.

[0119] 6. The dual-purpose turning machine is suitable for both the cross-cutting and cross-steaming process and the cross-cutting and vertical steaming process in the ALC production line.

[0120] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
