Description

Prefabricated building production line and prefabricated building structure

[0001] This application claims priority to Chinese patent applications No. 202311845133.4, 202311845141.9, 202311834147.6, 202311845125.X, 202311844938.7, and 202311845126.4, the entire disclosures of which are incorporated herein by reference. Technical Field

[0002] The present application relates to an assembled building production line and an assembled building structure, and in particular, to an assembled building production line and an assembled building structure. Background Art

[0003] Once a traditional building is completed, if requirements change, the existing structure must be demolished and a building with the required functions constructed. For example, in laboratory construction, the average lifespan of a typical fixed laboratory is 12-18 months. After an experimental project is completed, the laboratory's functional layout often needs to be changed, necessitating expansion, relocation, and other modifications to the laboratory site. Traditional laboratory design suffers from significant sustainability flaws, being costly, time-consuming, and disruptive to the surrounding environment, significantly increasing the time and financial costs of scientific research. Prefabricated laboratory units, by assigning different functions to each unit, allow multiple units to be assembled as needed to meet the requirements for the laboratory's functional layout. However, the existing laboratory assembly process is mostly manual, which not only cannot guarantee product quality and precision, but also involves working at height, posing a high safety risk.

[0004] Prefabricated modular laboratories have the characteristics of fast construction speed, good earthquake resistance, large usable area, light building weight, simple construction, flexible assembly, low labor and material consumption, and modular components that can be designed, and have great application value. Laboratory modules need to be prefabricated in the factory and then transported to the site for assembly. Due to the limitation of the factory area, in order to maximize the space utilization, the module production lines are usually arranged one by one to form multiple rows. Each production line is independent of each other. Laboratory modules are processed and manufactured accordingly on different production lines. When transferring the module room from the previous production line to the next production line, lifting tools are used. This method is very time-consuming and labor-intensive, requires a lot of labor, and has low overall production efficiency. At the same time, for laboratory modules such as plates, multiple processes and multi-layer processing are usually required. In the existing technology, dust is easily adsorbed on the surface of the plate during transportation, and subsequent processing still needs to be processed again, resulting in low overall production efficiency. Therefore, in response to the above problems, this application is proposed.

The first rotating assembly includes a first half gear 4, a second half gear 6, a first hinged rod 5 fixed to one side of the first half gear 4, a second hinged rod 7 fixed to one side of the second half gear 6, and a motor 3.

The first hinged rod 5 is hinged to the first connecting rod 8 via a hinge axis, and the second hinged rod 7 is hinged to the second connecting rod 9 via a hinge axis. Openings 10 are provided at both ends of the first connecting rod 8 and the second connecting rod 9, facilitating the articulation of the first and second articulated rods 5 and 7 with the first and second connecting rods 8 and 9. The rotating shaft of the first half gear 4 is connected to the output end of the motor 3 via a coupling, and the rotation of the second half gear 6 is rotationally connected to the base 1. The base 1 is provided with a recessed groove 17, and the first rotating assembly is disposed within the recessed groove 17, that is, the first and second half gears 4 and 6 are disposed within the recessed groove 17, and the rotating shaft of the second half gear 6 is rotationally connected to the inner wall of the recessed groove 17. The middle portion of the first connecting rod 8 is hinged to the middle portion of the second connecting rod 9 via a hinge axis. The second rotating assembly includes a third half gear 22, a fourth half gear 24, a third hinged rod 23 fixed to one side of the third half gear 22, and a fourth hinged rod 25 fixed to one side of the fourth half gear 24. The third half gear 22 is meshed with the fourth half gear 24. The end of the third hinged rod 23 is hinged to the opening 10 of the second connecting rod 9 at the end away from the second hinged rod 7 via a hinge axis. The end of the fourth hinged rod 25 is hinged to the opening 10 of the first connecting rod 8 at the end away from the first hinged rod 5 via a hinge axis. A corresponding groove 2 is provided at the bottom of the top plate 11. The second rotating assembly is disposed in the groove 2 at the bottom of the top plate 11. The rotating shafts of the third half gear 22 and the fourth half gear 24 are both rotatably connected to the inner wall of the groove 2 at the bottom of the top plate 11. Start the motor 3, the first half gear 4 and the second half gear 6 rotate, driving the first hinged rod 5 and the second hinged rod 7 to rotate upward at the same time. Under the action of the first connecting rod 8 and the second connecting rod 9, the third hinged rod 23 and the fourth hinged rod 25 rise synchronously, and the third half gear 22 and the fourth half gear 24 rotate in coordination, causing the top plate 11 to rise.A first support plate 13 is fixedly connected to one side of the top plate 11, and a movable plate 14 is sleeved on the first support plate 13. A first hydraulic telescopic rod 12 is arranged between the movable plate 14 and the top plate 11. Two adjacent second support plates 15 are hinged on both sides of the first support plate 13. The first hydraulic telescopic rod 12 is used to control the movable plate 14 to slide along the direction of the first support plate 13. The tops of the two adjacent second support plates 15 are connected by a second hydraulic telescopic rod 16. The second hydraulic telescopic rod 16 is used to control the two second support plates 15 to move closer to each other or expand outward to increase the lifting area. When the movable plate 14 slides toward the top plate 11 under the action of the first hydraulic telescopic rod 12, it drives the second support plates 15 on both sides to slide toward the top plate 11, and controls the second hydraulic telescopic rod 16 to retract, so that the two second support plates 15 move closer to each other. At this time, the lifting area is reduced, and it can lift small prefabricated laboratories. When the first hydraulic telescopic rod 12 is extended, the movable plate 14 moves away from the top plate 11, driving the second support plates 15 on both sides to slide away from the top plate 11. At the same time, the second hydraulic telescopic rod 16 is controlled to extend, so that the two second support plates 15 expand outward, extending the side of the first support plate 13, increasing the lifting area, and can lift large prefabricated buildings. In this embodiment, the first support plate 13 and the second support plate 15 are slidably connected to replace the multiple machines in traditional technology. This device is easier to control and convenient to operate. A limit plate is provided at the end of the first support plate 13 to prevent the movable plate 14 from separating from the first support plate 13. The second support plate 15 is provided with a trough 17, into which a baffle 18 is movably connected via a lifting assembly. This baffle 18 secures the edge of the prefabricated laboratory, preventing it from moving during lifting. The lifting assembly includes a rack 19, a gear 20, and a knob 21. The rack 19 is positioned on one side of the baffle 18 and meshes with the gear 20. The shaft of the gear 20 is connected to the knob 21, which is positioned on the outside of the second support plate 15 for easy operation. Turning the knob 21 causes the gear 20 to rotate, controlling the lifting and lowering of the rack 19 and the baffle 18. When the prefabricated laboratory needs to be fixed, turning the knob 21 causes the baffle 18 to rise under the action of the rack 19, and the baffle 18 is higher than the surface of the second support plate 15, thereby fixing the prefabricated laboratory; when the prefabricated laboratory does not need to be fixed, turning the knob 21 causes the baffle 18 to descend into the sink 17 under the action of the rack 19, avoiding affecting the prefabricated laboratory. Setting a lifting component can conveniently adjust the height of the baffle 18.

[0103] When the first and second hinged rods 5 and 7 are in engagement and rotated, the first hinged rod 5 and the second hinged rod 7 are rotated upward or downward, driving the first connecting rod 8 and the second connecting rod 9 to rotate crosswise, thereby lifting or pulling down the third hinged rod 23 and the fourth hinged rod 25. At this time, the third half gear 22 and the fourth half gear 24 rotate in the groove at the bottom of the top plate 11, thereby lifting or lowering the first support plate 13 and the second support plate 15, and thus completing the lifting or lowering of the prefabricated laboratory; during the lifting process of the prefabricated laboratory, the second support plate 15 is adjusted according to the size of the prefabricated laboratory. The second support plate 15 can slide in the direction of the first support plate 13 under the drive of the movable plate 14. When sliding close to the top plate 11, the second support plates 15 are moved closer to each other under the action of the second hydraulic telescopic rod 16, and are close to both sides of the first support plate 13, reducing the lifting area, so as to be suitable for prefabricated laboratories with small volumes. When sliding away from the top plate 11, the second support plates 15 move away from each other under the action of the second hydraulic telescopic rod 16, forming an expanded state, which can increase the lifting area to be suitable for large-scale prefabricated laboratories. The device can flexibly adjust the lifting area through the first support plate 13 and the second support plate 15, and has a wider applicability.

[0106] As shown in Figures 27-30, in the fifth optional embodiment of the present application, an automatic production fixture for prefabricated buildings is provided, including: a base 1, on which two clamping devices are movably arranged, and the two clamping devices are symmetrically arranged front to back; the clamping device includes an arc-shaped pendulum block 29, and the arc-shaped pendulum block 29 is rotatably arranged on the base 1, and two clamping components for clamping the air duct are fixedly connected to the top of the arc-shaped pendulum block 29, and the two clamping components are symmetrically arranged left to right, and the arc-shaped pendulum block 29 is transmission-connected to a driving part; the clamping component is coaxially arranged with the arc-shaped pendulum block 29; after the four clamping components clamp the air duct, the air duct can be driven to rotate around the axis of the arc-shaped pendulum block 29. During use, the air duct to be welded is clamped on the base 1 by four clamping assemblies, and the welding robot welds the joints of the air duct. When welding to the bottom of the air duct, due to the limitation of the welding robot's own range of motion, it is unable to accurately weld the bottom seam of the air duct. At this time, the driving part drives the arc-shaped deflection block 29 to rotate relative to the base 1, so that the bottom of the air duct rotates to one side, exposing the bottom of the air duct, so that the welding robot can weld the seam at the bottom of the air duct. A further optimized solution is provided, in which the clamping assembly includes a clamp support 2, which is fixed to one end of the top of the arc-shaped deflection block 29. The clamp support 2 is provided with an arc-shaped slide 6, which is slidably fitted with an arc-shaped slider 3, which is coaxially arranged with the arc-shaped deflection block 29. The arc-shaped slider 3 is transmission-connected to a second drive unit, which is arranged within the clamp support 2. The arc-shaped slider 3 is fixed to a support arm 8, with both ends of the support arm 8 respectively fixed to both ends of the arc-shaped slider 3. The support arm 8 is provided with an air duct fixing portion. A further optimized solution is provided, in which the air duct fixing portion includes a support plate 18, which is fixed to one side of the bottom of the support arm 8. A horizontal clamping portion is provided on the top of the support plate 18, and a vertical clamping portion is provided above the support plate 18. In a further optimized solution, the vertical clamping portion includes a sliding plate 31, which is slidably connected to the support arm 8 via a slide 9 vertically provided on the support arm 8. A rotating clamping portion is provided on the side of the sliding plate 31 away from the slide 9. The side of the sliding plate 31 near the slide 9 is threadedly connected to a threaded rod 10. The bottom of the threaded rod 10 is rotatably connected to the support plate 18. A sliding rod 11 is fixed to the support plate 18 and is located on one side of the threaded rod 10. The sliding rod 11 is slidably connected to the sliding plate 31. The threaded rod 10 is transmission-connected to a third drive unit. In a further optimized solution, the third drive unit includes a fourth motor 25. The fixed end of the fourth motor 25 is fixed to the bottom of the support plate 18, and the output shaft of the fourth motor 25 is axially connected to the threaded rod 10.

A through movable groove 22 is opened in the middle of the support plate 18, and the movable groove 22 is connected to the slide groove 21. A threaded slider 20 slides horizontally in the movable groove 22, and the threaded slider 20 is fixed to the splint 19; the two threaded sliders 20 located on the same arc-shaped deflection block 29 are threadedly connected to the two ends of a bidirectional threaded rod 23, and the bidirectional threaded rod 23 is rotatably arranged on the same side of the two support plates 18, and either end of the bidirectional threaded rod 23 is connected to the output shaft of the third motor 24, and the fixed end of the third motor 24 is fixed to the corresponding support plate 18. When clamping the air duct, first, the second bevel gear 16 is driven by the second motor 15 to rotate, and the second bevel gear 16 drives the first bevel gear 14 to rotate, and the first bevel gear 14 drives the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, it can drive the rotating plate 13 to rotate together, so that the rotating plate 13 can switch between a vertical state and a horizontal state. When the rotating plate 13 is in a vertical state, the air duct can be placed vertically on the supporting plate 18. Then the second motor 15 drives the rotating plate 13 to switch to a horizontal state. When the bottom of the air duct is placed on the supporting plate 18, the third motor 24 is started to drive the bidirectional threaded rod 23 rotates, and the two threaded sliders 20 are symmetrically arranged on the bidirectional threaded rod 23. When the bidirectional threaded rod 23 rotates, the two threaded sliders 20 can move relative to each other at the same time, and the two threaded sliders 20 approach each other, driving the two clamping plates 19 to clamp the bottom of the air duct. Then the fourth motor 25 starts to drive the threaded rod 10 to rotate. The rotation of the threaded rod 10 causes the sliding plate 31 to slide vertically along the slide 9 through the action of the thread. The setting of the slide rod 11 can cooperate with the threaded rod 10 to limit the rotation of the sliding plate 31, thereby causing the rotating plate 13 to contact and clamp the top of the air duct. At this time, the air duct is in a completely fixed state. Further optimization scheme, the second drive unit includes a gear 4, the gear 4 is arranged in a gear slot 7 opened in the middle of the clamp support 2, the gear 4 is rotatably connected to the inner wall of the gear slot 7, the outer wall of the gear 4 is meshed with the inner wall of the arc-shaped slider 3, the gear 4 shaft is connected to the output shaft of the first motor 5, and the fixed end of the first motor 5 is fixed to the clamp support 2. To further optimize the solution, the driving part includes a second gear 27, which is rotatably set in a slot 30 opened in the base 1. The second gear 27 is engaged with an arcuate tooth wall 28, and the arcuate tooth wall 28 is coaxially fixed to the outer side of the arcuate deflection block 29. The arcuate deflection block 29 is rotatably connected to the base 1. The second gear 27 is axially connected to the output shaft of the fifth motor 26, and the fixed end of the fifth motor 26 is fixed to the inner wall of the slot 30.During use, the second gear 27 is driven to rotate by the fifth motor 26. Since the second gear 27 is engaged with the arc-shaped tooth wall 28, and the arc-shaped tooth wall 28 is coaxially fixed to the outer side of the arc-shaped pendulum block 29, the second gear 27 can rotate the arc-shaped pendulum block 29 on the base 1 through the arc-shaped tooth wall 28, thereby driving the two clamp supports 2 to rotate at the same time. When the front and rear arc-shaped pendulum blocks 29 rotate at the same time, the air duct clamped on the clamp support 2 can rotate, exposing the bottom seam of the air duct. Subsequently, in order to further increase the rotation angle of the air duct, the first motor 5 can be started at this time to drive the gear 4 to rotate by the first motor 5. Since the gear 4 is engaged with the arc-shaped slider 3, the arc-shaped slider 3 can slide in the arc-shaped slide groove 6 opened on the clamp support 2. The arc-shaped deflection block 29 and the two arc-shaped sliders 3 on the same clamping device are coaxially arranged so that they rotate about the same center of the circle. This allows the air duct to rotate about the common center of the arc-shaped deflection block 29 and the two arc-shaped sliders 3. This increases the rotation angle of the air duct and fully exposes the seam at the bottom of the air duct.

[0108] The working principle of the present application is as follows: when in use, the staff first connects the electric push rod 13 and the welding mechanism 7 to the power supply. After the connection is turned on, the staff places the pipes to be welded into the two groups of clamping rings 17 respectively.

At this time, under the action of the second spring 31, the first roller 17 continues to exert force on the air duct assembly. Under the action of the first roller 17, the air duct assembly can slide within the second U-shaped frame 13 and dock with the already installed air duct assembly. For a further optimized solution, a first abrasive layer 6 is adhesively bonded to the top surface of the first top block 5. A second abrasive layer 7 is provided above the first abrasive layer 6, and the second abrasive layer 7 is fixedly connected to the inner top wall of the first U-shaped frame 2. Through the arrangement of the first abrasive layer 6 and the second abrasive layer 7, the friction between the first U-shaped frame 2 and the air duct assembly is increased, and at the same time, hard contact between the first U-shaped frame 2 and the air duct assembly is avoided. For a further optimized solution, a plurality of mounting holes are formed in the inner top wall of the second U-shaped frame 13. The plurality of mounting holes are arranged in an array. A second roller 21 is rotatably connected to the mounting hole through a second short shaft 30. The bottom end of the second roller 21 extends out of the mounting hole, and the rotation direction of the second roller 21 is the moving direction of the air duct assembly. With such an arrangement, the smoothness of the air duct assembly sliding within the second U-shaped frame 13 is further increased. For a further optimized solution, a third abrasive layer 16 is adhesively bonded to the top surface of the upper mounting plate 15. The friction between the second U-shaped frame 13 and the air duct assembly is increased. For a further optimized solution, a first friction ring 22 is sleeved on the outer edge of each first roller 17, and a second friction ring 23 is sleeved on the outer edge of each second roller 21. This prevents the air duct assembly to be installed from moving sideways, resulting in misalignment of the two air duct assemblies.

[0110] As shown in Figures 39-45, in the eighth embodiment of the present application, there is provided an air duct assembly transfer device, comprising: a conveyor line 1, arranged at the discharge end of the folding machine 2; a support frame, comprising a first plate body 4 located above the air duct 3, and a second plate body 5 connected to the conveyor line 1, the first plate body 4 and the second plate body 5 being fixed. The first plate body 4 and the second plate body 5 are fixed, so the conveyor line 1 synchronously moves the first plate body 4 during the process of conveying the second plate body 5. An adsorption unit 6 is arranged on the second plate body 5, and the adsorption end of the adsorption unit 6 is configured to adsorb the air duct 3 away from the side wall of the folding machine 2; an extrusion unit 7 is arranged on the first plate body 4, and the extrusion unit 7 includes an extrusion roller 701 moving in a vertical direction, and the extrusion roller 701 is configured to squeeze the air duct 3 close to the side wall of the folding machine 2 so that the air duct 3 is located between the extrusion roller 701 and the adsorption unit 6. Specifically, during the actual production process, the tube body has protruding connection ends on both sides, which are used to connect to other air ducts 3 during actual assembly. However, these connection ends affect the transportation of the air duct 3, so the adsorption unit 6 is used to adsorb the side walls of the air duct 3 to achieve the transportation of the air duct 3. At the same time, the air duct 3 produced by the folding machine 2 has two unconnected side walls, that is, there is a gap between the side wall of the air duct 3 close to the folding machine 2 and the side wall located below. Since the air duct 3 is formed by bending a piece of plate, during the transportation process, the side wall of the air duct 3 close to the folding machine 2 and the side wall located below have a tendency to separate. Therefore, an extrusion unit 7 is provided, and the extrusion roller 701 is used to extrude the side wall of the air duct 3 close to the folding machine 2, so that the two side walls are in contact, which facilitates transportation. In this embodiment, referring to Figures 39 and 42 , the device further includes: a negative pressure provider 8 fixed to the second plate 5; a first conduit 9 connecting the air inlet of the negative pressure provider 8 with the air outlet of the extrusion unit 7 to enable the extrusion roller 701 to move downward; and a second conduit 10 connecting the air inlet of the extrusion unit 7 with the air outlet of the adsorption unit 6 to secure the adsorption end of the adsorption unit 6 to the side wall of the air duct 3. Specifically, the negative pressure provider 8 is used to extract air and provide negative pressure. The adsorption unit 6 and the extrusion unit 7 utilize the same negative pressure provider 8. When the negative pressure provider 8 is in operation, air is first extracted from the extrusion unit 7 via the first conduit 9, causing the extrusion roller 701 in the extrusion unit 7 to move downward and squeeze the side wall of the air duct 3. Simultaneously, since the extrusion unit 7 is connected to the adsorption unit 6 via the second conduit 10, the adsorption unit 6 generates an adsorption force, thereby securing the adsorption unit 6 to the side wall of the air duct 3. In the above structure, the extrusion of the air duct 3 by the extrusion roller 701 and the adsorption of the air duct 3 by the adsorption unit 6 are both achieved by the negative pressure provider 8. On the other hand, when the negative pressure provider 8 starts working, the squeezing roller 701 first moves downward, and in the process of squeezing the air duct 3, it can push the air duct 3 toward the adsorption unit 6, thereby facilitating the adsorption unit 6 to adsorb the air duct 3. The negative pressure provider 8 is a vacuum pump or an air pump.In this embodiment, referring to Figures 39, 42 and 43, the extrusion unit 7 includes: a sleeve 702, which is sealed at both ends and connected to the first plate 4, a piston 703 is slidably fitted in the sleeve 702, and the air inlet end of the first conduit 9 and the air outlet end of the second conduit 10 are both arranged below the piston 703; a T-shaped rod 704, the vertical end of which extends into the sleeve 702 and is fixed to the piston 703, and the horizontal end extends out of the sleeve 702 and is located below the sleeve 702, and an extrusion roller 701 is respectively provided on both sides of the horizontal end of the T-shaped rod 704, and the extrusion roller 701 is rotatably connected to the horizontal end of the T-shaped rod 704. Specifically, when the negative pressure provider 8 is working, it extracts the gas in the sleeve 702, causing the piston 703 to move downward, and the piston 703 drives the T-shaped rod 704 to move downward, thereby driving the squeezing roller 701 to move downward. The squeezing roller 701 is used to squeeze the air duct 3 and push the air duct 3 toward the adsorption unit 6. Under the action of the second conduit 10, the adsorption unit 6 generates an adsorption force. Among them, the first conduit 9 is located above the second conduit 10. Among them, because the squeezing roller 701 can rotate relative to the T-shaped rod 704 and the squeezing roller 701 is a cylindrical structure, the squeezing roller 701 will not scratch the surface of the air duct 3 during the downward movement. In this embodiment, referring to Figure 43, a limit plate 705 is also included, which is fixed to the inner wall of the sleeve 702 and is located between the piston 703 and the first conduit 9. The limit plate 705 is configured to limit the piston 703. Specifically, the limiting plate 705 is used to limit the piston 703 so that after the piston 703 moves downward, it is always located above the first conduit 9. When the piston 703 is limited by the limiting plate 705 and cannot move, the negative pressure provider 8 can only evacuate the adsorption unit 6 through the sleeve 702 and the second conduit 10. In this embodiment, referring to Figure 43, a return spring 706 is also included, which is arranged in the sleeve 702, and the two ends are respectively fixed to the top of the piston 703 and the inner wall of the top of the sleeve 702. Specifically, after the air duct 3 is delivered to the predetermined position for unloading, the negative pressure provider 8 is closed or the air is supplied to the sleeve 702 in the opposite direction, so that the piston 703 moves upward. The piston 703 drives the squeezing roller 701 to move upward, so that the squeezing roller 701 moves above the air duct 3, and the adsorption unit 6 is separated from the air duct 3. A return spring 706 is provided in the sleeve 702. When the piston 703 moves downward, the return spring 706 is stretched. When the piston 703 moves upward, the return spring 706 retracts. The return spring 706 can assist the piston 703 in moving upward, thereby increasing the speed at which the piston 703 moves upward. In this embodiment, referring to Figures 42 and 43, the adsorption unit 6 includes: a pair of suction cups 601 fixed to the second plate 5; a connecting pipe 602, the two air inlet ends of which are respectively connected to the air outlet ends of the pair of suction cups 601, and the air outlet end of the connecting pipe 602 is connected to the air inlet end of the extrusion unit 7. Specifically, the suction cup 601 is used to be adsorbed on the outer wall of the air duct 3 to achieve a detachable connection between the air duct 3 and the second plate 5. The connecting pipe 602 is connected to the second conduit 10. The negative pressure provider 8 acts on the suction cup 601 through the sleeve 702, the second conduit 10, and the connecting pipe 602.In this embodiment, referring to Figures 42 and 44, an L-shaped connecting plate 11 is further included, one end of which is fixed to the first plate body 4 and the other end of which is connected to a distance-adjusting bolt 12. A plurality of mounting holes 13 are provided on the side wall of the second plate body 5 from bottom to top, and the end of the distance-adjusting bolt 12 is configured to extend into one of the mounting holes 13. The first plate body 4 and the second plate body 5 are detachably connected via the L-shaped connecting plate 11. Specifically, by providing the L-shaped connecting plate 11, which cooperates with the distance-adjusting bolt 12 and the mounting hole 13, a detachable connection between the first plate body 4 and the second plate body 5 is achieved. At the same time, the height of the first plate body 4 relative to the conveyor line 1 can be adjusted via the L-shaped connecting plate 11 according to the actual size of the air duct 3. In this embodiment, referring to Figures 40, 41, 42, and 43, a slide groove 14 is defined on the first plate 4. A slider 20 is slidably connected within the slide groove 14, and the extrusion unit 7 is fixed to the slider 20. The end of the slider 20, away from the extrusion unit 7, is rotatably connected to a threaded rod 15. The other end of the threaded rod 15 extends into the first plate 4 and is threadedly connected to the first plate 4. A driving swivel 16 is mounted and fixed on the threaded rod 15. Specifically, a sleeve 702 is fixed to the slider 20. The threaded rod 15 is rotated by the driving swivel 16, causing the threaded rod 15 to drive the slider 20 on the first plate 4, thereby changing the horizontal position of the sleeve 702 and the extrusion roller 701 to accommodate air ducts 3 of different sizes. In this embodiment, referring to Figures 39 and 45, the conveyor line 1 includes a pair of brackets 17. A conveyor roller assembly 18 is connected to the adjacent ends of the pair of brackets 17. The conveyor roller assembly 18 is configured to convey the second plate 5. Specifically, a conveyor roller assembly 18 is connected to the bracket 17 in a transmission manner. The conveyor roller assembly 18 is composed of multiple conveyor rollers, which enable the second plate 5 to move on the bracket 17. The second plate 5 drives the air duct 3, which has been adsorbed and clamped, to move on the bracket 17. Alternatively, the conveyor line 1 can be a conveyor belt, and the second plate 5 is fixed to the conveyor belt. Alternatively, the conveyor line 1 can be another type of conveying structure. Since the second plate 5 has a regular structure, a common conveying structure can achieve the conveyance of the second plate 5. In this embodiment, referring to Figure 45, a slide 19 is also included, which is fixed to the end of the second plate 5 away from the air duct 3. The bottom end of the slide 19 passes through a pair of brackets 17, and the conveyor roller assembly 18 is in transmission connection with the side walls of the slide 19. The slide 19 is used to connect to the bracket 17. The slide 19 is a T-shaped slide. Its vertical end passes between the two brackets 17 and is fixed to the second plate 5. The two side walls are in contact with the conveyor rollers and are driven by the conveyor rollers to move. Its horizontal end is located below the two brackets 17.Specifically, the folding machine 2 bends the plate to form an air duct 3. After the second plate body 5 moves on the bracket 17 to the discharge end of the folding machine 2, the second plate body 5 corresponds to the side wall of the air duct 3, and the first plate body 4 is located above the air duct 3. Then the negative pressure provider 8 is started, and the negative pressure provider 8 draws air from the sleeve 702 through the first conduit 9, so that the piston 703 drives the T-bar 704 and the squeezing roller 701 to move downward, and the squeezing roller 701 moves downward to squeeze the air duct 3 and drive the air duct 3 to move toward the second plate body 5. After the piston 703 moves down a certain distance, it is limited by the limit plate 705, and the negative pressure provider 8 continues to work, and draws air from the suction cup 601 through the sleeve 702 and the second conduit 10, so that the suction cup 601 is adsorbed on the air duct 3. Then the conveying roller group 18 works to drive the air duct 3 to move to a predetermined position on the bracket 17. After moving to the predetermined position, the negative pressure provider 8 stops working or supplies air in the reverse direction, so that the piston 703 drives the squeezing roller 701 to move upward and separate from the air duct 3, and the suction cup 601 is separated from the air duct 3 at the same time.
