Technical Field

[0001] The utility model relates to the technical field of flying shear devices, in particular to a strip steel flying shear cross-cutting device. Background Art

[0002] Flying shears are required for shearing during the strip processing. Traditional flying shears transport the sheared strip through a conveyor belt. Since the surface of the strip is relatively smooth, the strip is prone to slipping during transportation, causing the sheared strip to become skewed or colliding with each other, affecting transportation and subsequent stacking.

[0003] Prior art CN215847185U discloses a high-efficiency flying shear for aluminum strips, including a shearing mechanism and a conveying platform, a conveying platform is installed on one side of the shearing mechanism, and a conveyor is installed on the top surface of the conveying platform. Beneficial effect: The utility model adopts a conveying roller, one end of which is connected with a main pipe, and the two ends of the conveying roller are respectively connected to the side plates through the main pipe and the main shaft. During the flying shearing process, the aluminum strip is sheared by the shearing mechanism, and the conveying roller is pressed on the top surface of the aluminum strip. The sheared aluminum strip moves between the conveying roller and the top surface of the conveying platform. The vacuum pump extracts the air in the exhaust pipe, thereby extracting the air inside the conveying roller, so that the surface of the circular hole presents a negative pressure state, sucking the aluminum strip for transmission, and the transportation is more stable, reducing the phenomenon of the filter bag slipping on the top surface of the conveying platform, thereby avoiding the aluminum strip slipping and colliding with the next aluminum strip, thereby affecting the shearing of the next aluminum strip, so that the transportation is more stable and reliable, thereby improving the shearing stability of the aluminum strip and improving the shearing efficiency.

[0004] The above device extracts the air inside the conveyor roller so that the conveyor roller can absorb the aluminum strip, thereby improving the stability during transportation. However, when there is no aluminum strip on the conveyor roller, air will still be inhaled, which makes it easy for the conveyor roller to absorb external impurities, requiring staff to clean it, which is inconvenient to use.

The connecting rod 117 drives the connecting tube 105 to move upward through the spring 108, so that the through hole on the connecting tube 105 moves out of the negative pressure tube 106. At this time, the conveying roller 104 stops inhaling air, thereby avoiding the problem of the conveying roller 104 inhaling impurities when there is no strip steel on the conveying roller 104. It can be understood that the aforementioned scheme can be used to prevent the conveying roller 104 from inhaling external impurities, and can also be used to improve the sealing between the connecting tube 105 and the negative pressure tube 106.

[0023] For this specific embodiment, the frame 102 is installed on one side of the flying shear assembly 101, and the strip steel is transported to the flying shear assembly 101 through a conveyor belt (not shown in the figure), and the strip steel is sheared by the flying shear assembly 101, and finally the sheared strip steel is transported by the conveying assembly 103. The flying shear assembly 101 is a prior art, and its structure and working principle are not described in detail here.

[0024] The conveying roller 104 is rotatably connected to the frame 102 and is arranged on the frame 102. The connecting pipe 105 is fixedly connected to the frame 102 and rotatably connected to the conveying roller 104 and communicated with the conveying roller 104. The negative pressure pipe 106 is fixedly connected to the frame 102 and communicated with the connecting pipe 105 and is located on one side of the frame 102. The air pump 107 is fixedly connected to the frame 102 and communicated with the negative pressure pipe 106. The two ends of the spring 108 are fixedly connected to the frame 102 and communicated with the negative pressure pipe 106. The ends are respectively connected to the connecting tube 105 and the negative pressure tube 106, the spring 108 is sleeved on the connecting tube 105, and the pressing member 109 is arranged on the frame 102; the conveying assembly 103 is provided with a plurality of, and the frame 102 is also provided with a driving structure, through which the plurality of conveying rollers 104 are driven to rotate, the conveying rollers 104 are hollow, and a plurality of adsorption holes are arranged in the middle thereof, and a through hole is arranged on the connecting tube 105, and the connecting tube 105 is driven upward by the spring 108 The connecting pipe 105 is moved so that the through hole on the connecting pipe 105 is moved out of the negative pressure pipe 106. At this time, the connecting pipe 105 is not connected to the negative pressure pipe 106. When in use, when the sheared strip steel moves to the pressing member 109, the pressing member 109 descends under the action of the strip steel, thereby driving the connecting pipe 105 to descend, so that the through hole on the connecting pipe 105 extends into the negative pressure pipe 106, and the air inside the negative pressure pipe 106 is extracted by the air pump 107, thereby connecting the connecting pipe 105 and the negative pressure pipe 106. The conveying roller 104 can inhale air, and at this time the corresponding conveying roller 104 can adsorb the steel strip; when there is no steel strip on the conveying roller 104, the pressing member 109 is not subjected to force, so that the connecting pipe 105 is reset under the action of the spring 108, so that the through hole on the connecting pipe 105 is moved out of the negative pressure pipe 106. At this time, the conveying roller 104 without the steel strip above stops inhaling air, thereby achieving the purpose of preventing the conveying roller 104 from inhaling external impurities, which causes the problem of staff needing to clean it.

[0025] The tube body 110 is fixedly connected to the frame 102 , communicated with the air pump 107 , and located on one side of the frame 102 ; the sealing seat 111 is fixedly connected to the tube body 110 , connected to the spring 108 , and communicated with the connecting pipe 105 .

[0027] The bellows 113 can be extended and retracted, and a through hole is provided at the bottom of the insertion tube 114. When the downward pressing member 109 is not subjected to force, the spring 108 drives the abutment plate 115 to rise, so that the abutment plate 115 drives the insertion tube 114 to rise, and then the through hole on the insertion tube 114 moves to the inside of the sealing seat 111. At this time, air cannot enter the tube body 110 through the insertion tube 114, thereby disconnecting the connecting tube 105 and the negative pressure tube 106; when the downward pressing member 109 descends under the weight of the strip, the insertion tube 114 descends and drives the through hole thereon to descend, so that the through hole on the insertion tube 114 enters the tube body 110, and at this time the insertion tube 114 is connected to the tube body 110.

[0028] At the same time, the connecting rod 117 is fixedly connected to the abutment plate 115 and is arranged on the abutment plate 115; the abutment shaft 116 is rotatably connected to the connecting rod 117, and is slidably connected to the frame 102, and is located on one side of the connecting rod 117; when the strip moves onto the abutment shaft 116, the weight of the strip presses the abutment shaft 116 downward, thereby driving the connecting rod 117, the abutment plate 115 and the insertion tube 114 to descend, thereby achieving the purpose of driving the insertion tube 114 to descend.

[0029] When the strip steel flying shear cross-cutting device of this embodiment is used, the air pump 107 is used to pump the inside of the tube body 110 to a negative pressure. When the strip steel moves to above the abutment shaft 116, the abutment shaft 116 descends under the weight of the strip steel, thereby driving the connecting rod 117, the abutment plate 115 and the insertion tube 114 to descend, so that the through hole on the insertion tube 114 moves from the sealing seat 111 to the tube body 110. At this time, the tube body 110 is connected to the insertion tube 114, thereby making the corresponding conveying The roller 104 can inhale air to adsorb the steel strip thereon; when the steel strip moves away from the abutment shaft 116, the abutment plate 115 and the insertion tube 114 are reset under the action of the spring 108, thereby causing the through hole on the insertion tube 114 to move to the inside of the sealing seat 111. At this time, the insertion tube 114 is not connected to the tube body 110, so that the corresponding conveying roller 104 stops inhaling air, thereby preventing the conveying roller 104 from inhaling external impurities, which requires cleaning by the staff.
