Description

Technical Field

[0001] This utility model relates to a thin plate feeding device for pressure vessel production, belonging to the field of auxiliary equipment for pressure vessel production. Background Technology

[0002] Pressure vessels are common equipment in the chemical industry, primarily used in heat transfer, reaction, and storage processes during chemical production. Specific applications include reaction vessels, heat exchange vessels, and storage vessels. The fabrication of pressure vessels mainly involves the production of the vessel body and the end caps. During vessel body fabrication, plate material must first be cut. This cutting requires a plate cutting device. Existing plate cutting devices often lack plate limiting devices during plate transport, leading to significant processing errors and unsatisfactory performance.

[0003] To address this, Chinese utility model patent CN216151828U discloses a plate cutting device for pressure vessel production. While the aforementioned prior art achieves the limitation of the metal plate, it only limits the two sides of the metal plate, lacking a limiting structure for the ends. This results in errors in the length of the cut metal plate, and the application effect remains unsatisfactory. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a thin plate feeding device for pressure vessel production that can limit the end of metal sheet.

[0005] The thin plate unloading device for pressure vessel production of this utility model includes a frame, on which a feeding component and an unloading component are connected. Multiple support columns are fixedly connected to the frame at the junction of the feeding component and the unloading component. A top plate is fixedly connected between the tops of each support column. A cutting component and a pressing component are connected to the top plate. A gantry frame is connected to the frame corresponding to the unloading component. A positioning cylinder is installed on the top wall of the gantry frame. The piston rod of the positioning cylinder passes through the top wall of the gantry frame and is fixedly connected to a positioning plate. Two positioning guide sleeves are also fixedly connected to the top wall of the gantry frame. A positioning guide rod is slidably fitted inside each of the two positioning guide sleeves. The lower ends of the two positioning guide rods are fixedly connected to the positioning plate.

[0006] Furthermore, the frame is provided with a T-shaped sliding groove, and both ends of the gantry frame are fixedly connected to the T-shaped sliding groove by T-bolts and locking nuts, with the T-bolts and T-shaped sliding grooves slidingly adapted to each other.

[0007] Furthermore, the feeding assembly includes several feeding rollers rotatably mounted on the frame and a feeding mounting plate fixedly connected to the frame. A feeding motor is mounted on the feeding mounting plate, and a conveyor belt is connected between each feeding roller. The feeding rollers are connected to each other, and one of the feeding rollers is connected to the feeding motor.

[0008] Furthermore, the feeding assembly includes several feeding rollers rotatably mounted on the frame and a feeding mounting plate fixedly connected to the frame. A feeding motor is mounted on the feeding mounting plate, and the feeding rollers are connected to each other, with one feeding roller connected to the feeding motor.

[0009] Furthermore, the pressing assembly includes a pressing cylinder installed on the top of the top plate. The piston rod of the pressing cylinder passes through the top plate and is fixedly connected to a pressing plate. Multiple pressing guide sleeves are fixedly connected to the top plate. Each pressing guide sleeve is slidably fitted with a pressing guide shaft. The lower end of each pressing guide shaft is fixedly connected to the pressing plate.

[0010] Furthermore, the cutting assembly includes two side plates fixedly connected to the front and rear sides of the top plate, with a lead screw rotatably connected between the two side plates. One end of the lead screw passes through the side plate and is connected to a displacement motor. A movable nut is fitted on the lead screw. Two linear guide rails are fixedly connected to the bottom of the top plate. A slider is slidably connected to each of the two linear guide rails. A movable plate is fixedly connected between the two sliders and the movable nut. A cutting mechanism is installed on the movable plate.

[0011] Furthermore, the cutting mechanism includes a blade holder fixedly connected to a movable plate, a cutting motor mounted on the blade holder, a cutting blade rotatably connected to the bottom of the blade holder, and the cutting blade connected to the cutting motor.

[0012] Working principle and process:

[0013] In operation, the feeding motor activates, driving the feeding roller to rotate, which in turn drives the conveyor belt to move, conveying the metal sheet on the conveyor belt to the right. When the right end of the metal sheet abuts against the positioning plate, the feeding motor stops. Then, the pressing cylinder activates, driving the pressing plate downward under the cooperation of the pressing guide sleeve and the pressing guide shaft, pressing the metal sheet tightly onto the unloading roller. Next, the cutting motor activates, driving the cutting blade to rotate. Then, the displacement motor activates, driving the lead screw to rotate, which in turn drives the moving nut to move back and forth. This, in turn, drives the moving plate to move back and forth under the cooperation of the linear guide rail and the slider, thereby driving the cutting blade to move back and forth through the blade holder, achieving the cutting of the metal sheet. After cutting, the pressing cylinder retracts, driving the pressing plate upward and releasing the pressure on the metal sheet. At the same time, the positioning cylinder retracts, driving the positioning plate upward under the cooperation of the positioning guide sleeve and the positioning guide rod, so that the positioning plate releases the restriction on the metal sheet. Finally, the unloading motor activates, driving each unloading roller to rotate, thereby outputting the cut metal sheet.

[0014] The advantages of this utility model compared with the prior art are:

[0015] The thin plate feeding device for pressure vessel production described in this utility model is equipped with a lifting positioning plate, which can limit the end of the metal plate, effectively ensuring the accuracy of the metal plate feeding length and having good applicability.

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0024] Example 1:

[0025] like Figures 1 to 6As shown, the thin plate unloading device for pressure vessel production of this utility model includes a frame 1, on which a feeding component and an unloading component are connected. Multiple support columns 9 are fixedly connected to the frame 1 at the junction of the feeding and unloading components. A top plate 10 is fixedly connected between the tops of each support column 9. A cutting component and a pressing component are connected to the top plate 10. A gantry frame 11 is connected to the frame 1 corresponding to the unloading component. A positioning cylinder 15 is installed on the top wall of the gantry frame 11. The piston rod of the positioning cylinder 15 passes through the top wall of the gantry frame 11 and is fixedly connected to a positioning plate 12. Two positioning guide sleeves 13 are also fixedly connected to the top wall of the gantry frame 11. Positioning guide rods 14 are slidably fitted inside each of the two positioning guide sleeves 13, and the lower ends of the two positioning guide rods 14 are fixedly connected to the positioning plate 12.

[0026] In use, the feeding assembly is used to feed the metal sheet 5 to the right, so that the right end of the metal sheet 5 abuts against the positioning plate 12. Then the pressing assembly is activated to press the metal sheet 5 tightly onto the unloading assembly. Then the cutting assembly is activated to cut the metal sheet 5. After cutting, the pressing assembly reverses to release the pressure on the metal sheet 5. At the same time, the positioning cylinder 15 retracts, and with the cooperation of the positioning guide sleeve 13 and the positioning guide rod 14, it drives the positioning plate 12 to move upward, so that the positioning plate 12 releases the restriction on the metal sheet 5. Then the unloading assembly is activated to output the cut metal sheet 5.

[0027] Example 2:

[0028] like Figures 1 to 6 As shown, based on Example 1:

[0029] Furthermore, the frame 1 is provided with a T-shaped slide groove 23. Both ends of the gantry frame 11 are fixedly connected to the T-shaped slide groove 23 by T-bolts 24 and locking nuts 25. The T-bolts 24 and the T-shaped slide groove 23 are slidably adapted to each other. By sliding the T-bolts 24 to different positions within the T-shaped slide groove 23 for fixing, the position of the gantry frame 11 can be adjusted, thereby adjusting the position of the positioning plate 12 to accommodate cutting metal plates 5 of different lengths.

[0030] Furthermore, the feeding assembly includes several feeding rollers 20 rotatably mounted on the frame 1 and a feeding mounting plate 2 fixedly connected to the frame 1. A feeding motor 3 is mounted on the feeding mounting plate 2. Conveyor belts 4 are connected between each feeding roller 20, and one feeding roller 20 is connected to the feeding motor 3. The feeding motor 3 drives each feeding roller 20 to rotate, thereby driving the conveyor belt 4 to transport the metal sheet 5. The belt conveyor method ensures sufficient contact with the metal sheet 5, improving the stability of the metal sheet 5 transport.

[0031] Furthermore, the feeding assembly includes several feeding rollers 8 rotatably mounted on the frame 1 and a feeding mounting plate 6 fixedly connected to the frame 1. A feeding motor 7 is mounted on the feeding mounting plate 6, and the feeding rollers 8 are connected to each other, with one feeding roller 8 connected to the feeding motor 7. The feeding motor 7 drives the feeding rollers 8 to rotate, thereby outputting the cut metal sheet 5. This roller-based feeding method is simple in structure and low in cost.

[0032] Furthermore, the pressing assembly includes a pressing cylinder 19 mounted on the top of the top plate 10. The piston rod of the pressing cylinder 19 passes through the top plate 10 and is fixedly connected to a pressing plate 16. Multiple pressing guide sleeves 18 are fixedly connected to the top plate 10. Each pressing guide sleeve 18 is slidably fitted with a pressing guide shaft 17, and the lower end of each pressing guide shaft 17 is fixedly connected to the pressing plate 16. When the pressing cylinder 19 is activated, the pressing plate 16 is driven to move downward under the cooperation of the pressing guide sleeves 18 and the pressing guide shafts 17, thereby pressing the metal sheet 5 tightly onto the feeding roller 8.

[0033] Furthermore, the cutting assembly includes two side plates 21 fixedly connected to the front and rear sides of the top plate 10. A lead screw 26 is rotatably connected between the two side plates 21. One end of the lead screw 26 passes through the side plate 21 and is connected to a displacement motor 22. A movable nut 27 is fitted on the lead screw 26. Two linear guide rails 28 are fixedly connected to the bottom of the top plate 10. A slider 29 is slidably connected to each of the two linear guide rails 28. A movable plate 33 is fixedly connected between the two sliders 29 and the movable nut 27. The cutting mechanism is mounted on the movable plate 33. When the displacement motor 22 is activated, it drives the lead screw 26 to rotate, thereby driving the movable nut 27 to move back and forth. This, in turn, drives the movable plate 33 to move back and forth with the cooperation of the linear guide rails 28 and the sliders 29, thus driving the cutting mechanism to move back and forth, thereby realizing the cutting and blanking of the metal sheet 5.

[0034] Furthermore, the cutting mechanism includes a blade holder 30 fixedly connected to the movable plate 33, a cutting motor 31 mounted on the blade holder 30, and a cutting blade 32 rotatably connected to the bottom of the blade holder 30. The cutting blade 32 is connected to the cutting motor 31. By actuating the cutting motor 31, the cutting blade 32 is driven to rotate, thereby realizing the cutting and blanking of the metal sheet 5.
