Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, and in particular to a shearing machine conveying and positioning device. Background Technology

[0002] A shearing machine is a device used to cut metal sheets. It uses powerful shearing force to precisely cut metal sheets of various thicknesses and materials into the required specifications according to pre-set size and shape requirements, providing suitable sheet material for subsequent metal processing and manufacturing processes. It plays an important role in many industrial fields.

[0003] In existing technology, conventional shearing machines use conveyor belts to transport sheet metal for shearing operations. However, when used with heavy sheet metal that has oil and dust on its surface, the conveyor belt has to overcome greater resistance to provide traction due to the weight of the sheet. Furthermore, the oil and dust on the sheet surface reduce the coefficient of friction between the conveyor belt and the sheet, significantly decreasing the frictional force. Therefore, the conveyor belt is prone to slippage during operation, and the sheet metal may tilt during transport. When the conveyor belt slips, the frictional force on different parts of the sheet metal becomes uneven. One side may shift relative to the other due to insufficient friction, leading to overall tilting of the sheet metal. Once the sheet metal tilts into the shearing zone, the cutting direction of the shearing blade is inconsistent with the actual direction of the sheet metal, resulting in irregular edges, burrs, and other problems. This severely affects the shearing quality and may even damage the shearing blade, increasing equipment maintenance costs and the risk of production interruption. It can also lead to sheet metal that does not meet dimensional requirements and potentially waste raw materials. Therefore, it is necessary to improve the shearing machine's conveyor positioning device to solve these problems. Utility Model Content

[0005] The technical solution of this utility model is as follows: a shearing machine conveying and positioning device, including a conveying frame, and a first conveying wheel rotatably connected to the conveying frame. An anti-slip pad is fixedly connected to the first conveying wheel, and a pulley is fixedly connected to the first conveying wheel. A synchronous belt is driven to the pulley, so that adjacent first conveying wheels rotate synchronously and in the same direction through the synchronous belt. An adjustment mechanism is provided on the conveying frame to adjust the angle when the plate enters the shearing machine.

[0006] Preferably, there are several pulleys, and the timing belt is positioned between two adjacent pulleys.

[0007] Preferably, a dual-axis motor is fixedly connected to the conveyor frame, and a drive shaft is fixedly connected to the output end of the dual-axis motor. The drive shaft is rotatably connected to the conveyor frame, and a first gear is fixedly connected to the drive shaft. A second gear meshes with the first gear, and the second gear is fixedly connected to a first conveyor wheel. A rotating plate is rotatably connected to the conveyor frame, and a tilting frame is fixedly connected to the rotating plate. A threaded rod is rotatably connected to the tilting frame, and a sliding frame is threadedly connected to the threaded rod. The sliding frame is slidably connected to the tilting frame, and a positioning frame is fixedly connected to the bottom of the sliding frame. A second conveyor wheel is rotatably connected to the positioning frame. The rotation of the threaded rod causes the second conveyor wheel to descend and press against the surface of the plate to be conveyed. A positioning mechanism that restricts the rotation of the rotating plate is fixedly connected to the conveyor frame.

[0008] Preferably, the positioning mechanism includes a positioning plate fixedly connected to the conveyor frame, and bolts are inserted into the interior of the positioning plate, with the bolts threaded onto the rotating plate.

[0009] Preferably, the rotating plate contacts the positioning plate, and the angle between the flipping frame and the rotating plate is positioned by the positioning plate.

[0010] Preferably, the adjustment mechanism includes a rotating seat fixedly connected to the conveyor frame, an angle ruler fixedly connected to the rotating seat, a mounting plate rotatably connected to the rotating seat, a pointer fixedly connected to the mounting plate, a positioning rod fixedly connected to the bottom of the conveyor frame, a support leg slidably connected to the positioning rod, a connecting rod fixedly connected to the inner side of the support leg, and an electric telescopic rod fixedly connected between the connecting rod and the conveyor frame. The electric telescopic rod extends and retracts, causing the support leg to contact the ground.

[0011] Preferably, the support leg has a matching groove at the corresponding position of the positioning rod, and the support leg slides on the positioning rod through the groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. Multiple first conveyor wheels rotate synchronously and in the same direction. The anti-slip pads with anti-slip textures on their surfaces increase the friction between the wheels and the sheet metal, thus ensuring stable conveying of the sheet metal. The multi-point contact synchronous conveying and high friction effectively prevent the sheet metal from slipping and ensure the conveying accuracy of the sheet metal.

[0014] 2. The conveyor frame is tilted together with the sheet metal, which allows control over the angle at which the sheet metal enters the shearing machine. This enables the shearing machine to cut the sheet metal from different angles, meeting various shearing needs and improving work efficiency. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-7 This utility model provides an embodiment of a shearing machine conveying and positioning device, including a conveying frame 1 and a first conveying wheel 21 rotatably connected to the conveying frame 1. An anti-slip pad 22 is fixedly connected to the first conveying wheel 21, and a pulley 23 is fixedly connected to the first conveying wheel 21. A synchronous belt 24 is driven to the pulley 23, enabling adjacent first conveying wheels 21 to rotate synchronously and in the same direction via the synchronous belt 24. The conveying frame 1 is equipped with an adjustment mechanism for adjusting the angle of the sheet metal entering the shearing machine. The sheet metal is placed on the surface of the first conveying wheel 21, and the tilt angle of the conveying frame 1 relative to the shearing machine can be adjusted by the adjustment mechanism. The first conveying wheel 21 increases the friction with the sheet metal through the anti-slip pad 22. The first conveying wheel 21 rotates to convey the sheet metal, and while rotating, it drives the pulley 23. The pulley 23, through the synchronous belt 24, enables adjacent first conveying wheels 21 to rotate synchronously and in the same direction. Then, several first conveying wheels 21 rotate synchronously to convey the sheet metal into the shearing machine for shearing operations.

[0025] Please see Figures 1-5 In this embodiment, several pulleys 23 are provided, and a synchronous belt 24 is arranged between two adjacent pulleys 23. The synchronous belt 24 enables adjacent first conveying wheels 21 to rotate synchronously in the same direction, cooperating with each other, so that several first conveying wheels 21 rotate simultaneously in the same direction, thereby cooperating to convey the plate. A dual-axis motor 25 is fixedly connected to the conveyor frame 1, and a drive shaft 26 is fixedly connected to the output end of the dual-axis motor 25. The drive shaft 26 is rotatably connected to the conveyor frame 1. A first gear 27 is fixedly connected to the upper part of the conveyor frame 1. A second gear 28 meshes with the first gear 27. The second gear 28 is fixedly connected to the first conveyor wheel 21. A rotating plate 29 is rotatably connected to the rotating plate 29. A tilting frame 210 is fixedly connected to the rotating frame 210. A threaded rod 211 is rotatably connected to the tilting frame 210. A sliding frame 212 is threadedly connected to the threaded rod 211. The sliding frame 212 is slidably connected to the tilting frame 210. A positioning frame 213 is fixedly connected to the bottom of the sliding frame 212. A second conveyor wheel 214 is rotatably connected to the positioning frame 213. Rotation of the threaded rod 211 causes the second conveyor wheel 214 to descend and press against the surface of the plate to be conveyed. A positioning mechanism that restricts the rotation of the rotating plate 29 is fixedly connected to the conveyor frame 1. Rotation of the threaded rod 211 causes the second conveyor wheel 214 to descend and press against the surface of the plate to be conveyed. A positioning mechanism that restricts the rotation of the rotating plate 29 is fixedly connected to the conveyor frame 1. Rotation of the threaded rod 211 causes the second conveyor wheel 214 to descend and press against the surface of the plate to be conveyed. The pressure is lowered onto the surface of the sheet material, further increasing the friction between the sheet material and the anti-slip pad 22. This also prevents the sheet material from warping during shearing, ensuring both conveying and shearing accuracy. The positioning mechanism includes a positioning plate 215 fixedly connected to the conveyor frame 1. Bolts 216 are inserted into the interior of the positioning plate 215 and are threaded onto the rotating plate 29. The relevant components of the positioning rotating plate 29 can be replaced as needed, such as snap-fit ​​or clamping mechanisms, to position the angle of the rotating plate 29. The rotating plate 29 contacts the positioning plate 215, and the angle between the tilting frame 210 and the rotating plate 29 is positioned by the positioning plate 215. By holding the rotating plate 29 against the positioning plate 215, excessive rotation of the rotating plate 29 can be prevented. With the positioning of the bolts 216, the tilting frame 210 can be prevented from tilting on its own.

[0026] Please see Figure 1 , Figures 6-7In this embodiment, the adjustment mechanism includes a rotating seat 31 fixedly connected to the conveyor frame 1, an angle ruler 32 fixedly connected to the rotating seat 31, an mounting plate 33 rotatably connected to the rotating seat 31, a pointer 34 fixedly connected to the mounting plate 33, a positioning rod 35 fixedly connected to the bottom of the conveyor frame 1, a support leg 36 slidably connected to the positioning rod 35, a connecting rod 37 fixedly connected to the inner side of the support leg 36, and an electric telescopic rod 38 fixedly connected between the connecting rod 37 and the conveyor frame 1. The electric telescopic rod 38 extends and retracts, causing the support leg 36 to contact the ground. The entire device is fixed to the shearing machine by the mounting plate 33. The conveyor frame 1 rotates by the cooperation between the rotating seat 31 and the mounting plate 33, adjusting the tilt angle of the conveyor frame 1 relative to the shearing machine, thereby controlling the angle at which the board enters the shearing machine. The support leg 36 has a matching groove at the corresponding position of the positioning rod 35, and the support leg 36 slides on the positioning rod 35 through the groove. The groove limits the support leg 36, preventing it from tilting and allowing it to slide in a straight line.

[0027] During operation, first unscrew bolt 216 to disengage it from rotating plate 29. Then, rotate plate 29 and tilting frame 210 are flipped. The plate is then placed on the surface of anti-slip mat 22. Next, tilting frame 210 and rotating plate 29 are reset, with rotating plate 29 contacting positioning plate 215. Bolt 216 is then screwed through positioning plate 215 into rotating plate 29 to position it, thus positioning tilting frame 210. Rotating threaded rod 211 raises and lowers sliding frame 212, which in turn drives positioning frame 213. Positioning frame 213 presses against the plate surface via second conveyor wheel 214, ensuring the plate is tightly against first conveyor wheel 21. First conveyor wheel 21 increases friction via anti-slip mat 22. Dual-axis motor 25 drives the transmission. Shaft 26 drives the first gear 27, which in turn drives the second gear 28. The second gear 28 drives the first conveyor wheel 21. The first conveyor wheel 21 conveys the sheet material through the anti-slip pad 22. When the sheet material moves, friction causes the second conveyor wheel 214 to rotate. The rotation of the first conveyor wheel 21 drives the pulley 23. The pulley 23 rotates synchronously with the adjacent first conveyor wheel 21 through the synchronous belt 24. The rotating seat 31 is rotated, and the rotating seat 31 tilts together with the conveyor frame 1. The tilt angle of the conveyor frame 1 can be determined by the pointer 34 and the angle ruler 32. The extension and retraction of the electric telescopic rod 38 can drive the connecting rod 37. The connecting rod 37 drives the support leg 36. The height of the extension and retraction of the support leg 36 is adjusted so that the support leg 36 contacts the ground and supports the conveyor frame 1.

[0028] Through the above steps, multi-point contact synchronous conveying with high friction effectively prevents the sheet material from slipping, ensuring the conveying accuracy of the sheet material. This solves the problem of conveyor belt slippage when conveying heavy sheet materials with oil and dust on their surface.
