Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to a shearing machine feeding device. Background Technology

[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. It uses a moving upper blade and a fixed lower blade, with a reasonable blade gap, to apply shearing force to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions.

[0003] A search revealed a Chinese patent with publication number CN220462426U that discloses a feeding device for a shearing machine. The key technical point of this patent is that it solves the problem that existing feeding devices for shearing machines lack clamping for the sheet metal during use, and the sheet metal is prone to displacement during the conveying process, resulting in the sheet metal not meeting the specified size during shearing and thus wasting the sheet metal.

[0004] However, existing technologies have found that when feeding sheet metal, it is necessary to manually place each sheet onto the conveyor belt, which is time-consuming, labor-intensive, and results in low shearing efficiency. To address this problem, this application proposes a solution by incorporating components such as a threaded rod, sliding block, inclined block, and spring. The forward and reverse rotation of the threaded rod allows the inclined block to sequentially transfer the bottom sheet onto the conveyor belt, achieving automatic feeding. This eliminates the need for manual sheet delivery, saving time and labor and improving shearing efficiency. Therefore, a new solution is needed to address this issue. Utility Model Content

[0005] In view of the above-mentioned background technology, the existing technology has the shortcomings and defects of requiring manual placement of each sheet of board on the conveyor belt, which is time-consuming, labor-intensive, and has low shearing efficiency.

[0006] This utility model discloses a feeding device for a shearing machine, including a support frame. A motor and a fixing block are fixedly connected to the inner bottom wall of the support frame. A sliding groove is formed on the upper surface of the fixing block. A sliding block is slidably connected to the inner wall of the sliding groove. A housing is fixedly connected to the upper surface of the sliding block. An inclined block is slidably connected to the inner wall of the housing. Two springs are fixedly connected to the bottom surface of the inclined block. The bottom end of each spring is fixedly connected to the inner bottom wall of the housing. A threaded rod is fixedly connected to the output shaft of the motor. The outer surface of the threaded rod is threadedly connected to the inner wall of the sliding block. The outer surface of the threaded rod is rotatably connected to the inner wall of the fixing block.

[0007] Furthermore, a limiting shell is fixedly connected to the upper surface of the support frame, and a bidirectional screw is rotatably connected to the inner wall of the limiting shell. Two baffles are threadedly connected to the outer surface of the bidirectional screw.

[0008] Furthermore, the inner wall of the limiting shell is fixedly connected to two guide rods, and the outer surface of each guide rod is slidably connected to the inner wall of the corresponding baffle.

[0009] Furthermore, a limit frame is fixedly installed on the inner bottom wall of the support frame, and the inner wall of the support frame is rotatably connected with support rollers and transmission rollers arranged at equal distances.

[0010] Furthermore, a second motor is fixedly connected to the bottom surface of the support frame, a first pulley is fixedly connected to the output shaft of the second motor, and a belt assembly is driven to the outer surface of the first pulley.

[0011] Furthermore, the inner wall of the belt assembly is connected to a second pulley, the back of which is fixedly connected to the front of the corresponding transmission roller.

[0012] Furthermore, a conveyor belt is provided above the support frame, and the inner wall of the conveyor belt is connected to the outer surface of the corresponding drive roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up components such as a sliding block, a threaded rod, an inclined block, and a spring, allows for automatic feeding of sheet metal when the motor drives the threaded rod to rotate. The threaded rod then moves the sliding block, which in turn moves the inclined block through the housing, thus feeding the bottom sheet metal and pushing it out. Then, the motor reverses direction, and the inclined surface of the inclined block compresses the spring, causing the inclined block to descend below the sheet metal until the sliding block returns to its original position. The inclined block then returns to its original position under the action of the spring, and the inclined block once again presses against the bottom sheet metal. This process is repeated, achieving automatic feeding without the need for manual feeding of sheet metal one by one, saving time and effort and improving shearing efficiency.

[0015] 2. This utility model incorporates components such as a limiting shell, a bidirectional screw, a baffle, and a guide rod. The limiting shell is located on the upper surface of the support frame, and the bidirectional screw is installed on the inner wall of the limiting shell. Rotating the bidirectional screw allows the baffle to move relative to the support frame. The guide rod limits the position of the baffle, thereby allowing the distance between the two baffles to be adjusted. This facilitates the stacking of plates of different widths. Furthermore, the left side of the limiting shell has a groove of a certain thickness, allowing the bottom plate to pass through, while the upper plates are confined inside the limiting shell. This, along with the inclined block, helps to push the bottom plate out. Attached Figure Description

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5This utility model discloses a feeding device for a shearing machine, comprising a support frame 9.

The connection between the threaded rod 5 and the inner wall of the fixed block 2 is a rotatable connection, which limits the movement of the threaded rod 5.

[0027] In a preferred embodiment, a limiting shell 10 is fixedly connected to the upper surface of the support frame 9. The limiting shell 10 is installed on the upper surface of the support frame 9 and is set as a fixed connection to achieve the positioning and installation effect of the limiting shell 10. A bidirectional screw 11 is rotatably connected to the inner wall of the limiting shell 10. The bidirectional screw 11 is installed on the inner wall of the limiting shell 10 and is set as a rotatable connection to achieve the limiting of the bidirectional screw 11. Two baffles 12 are threadedly connected to the outer surface of the bidirectional screw 11. The baffles 12 are installed on the surface of the bidirectional screw 11. By rotating the bidirectional screw 11, the two baffles 12 can move relative to each other, which facilitates the adjustment of the distance between the baffles 12 and limits the plates of different widths.

[0028] like Figure 3 As shown, two guide rods 13 are fixedly connected to the inner wall of the limiting shell 10. The guide rods 13 are installed on the inner wall of the limiting shell 10 and are set as fixed connections to achieve the positioning and installation effect of the guide rods 13. The outer surface of each guide rod 13 is slidably connected to the inner wall of the corresponding baffle 12. The guide rods 13 are connected to the corresponding baffles 12 and are set as slidable connections to achieve the limiting of the baffles 12 through the guide rods 13.

[0029] In this embodiment, a limiting frame 14 is fixedly installed on the inner bottom wall of the support frame 9. The limiting frame 14 is connected to the inner bottom wall of the support frame 9. The limiting frame 14 can limit the movement of the motor 1. The inner wall of the support frame 9 is rotatably connected with support rollers 15 and transmission rollers 16 arranged at equal distances. The support rollers 15 and transmission rollers 16 are installed on the inner wall of the support frame 9 and are configured to be rotatably connected. The support frame 9 can support and limit the movement of the support rollers 15 and transmission rollers 16.

[0030] Combination Figure 2 and Figure 5 A second motor 17 is fixedly connected to the bottom surface of the support frame 9. The second motor 17 is installed on the bottom surface of the support frame 9 and is set as a fixed connection to realize the installation of the second motor 17. A pulley 18 is fixedly connected to the output shaft of the second motor 17 and is set as a fixed connection. The second motor 17 enables the pulley 18 to rotate. A belt group 19 is connected to the outer surface of the pulley 18. The belt group 19 is set on the surface of the pulley 18 and connected to it.

[0031] In a preferred embodiment, a pulley 20 is connected to the inner wall of the belt assembly 19. The pulley 20 is installed on the inner wall of the belt assembly 19. Through the connection between the belt assembly 19 and the pulley 20, when the pulley 18 rotates, the pulley 20 can rotate. The back of the pulley 20 is fixedly connected to the front of the corresponding transmission roller 16. The back of the pulley 20 is connected to one of the transmission rollers 16, which is set as a fixed connection. When the pulley 20 rotates, the transmission roller 16 can rotate.

[0032] In this embodiment, a conveyor belt 21 is provided above the support frame 9. The inner wall of the conveyor belt 21 is connected to the outer surface of the corresponding drive roller 16. The conveyor belt 21 is connected to the drive roller 16. Through the connection between the drive roller 16 and the conveyor belt 21, when one of the drive rollers 16 rotates, the conveyor belt 21 can transport the plate.

[0033] The implementation principle is as follows: Rotating the bidirectional screw 11 allows the two baffles 12 to slide on the surface of the guide rod 13. The distance between the two baffles 12 is adjusted according to the width of the plate. Then, the plate is stacked on top of the support roller 15. When the plate is being transferred, motor 1 drives the threaded rod 5 to rotate, which in turn drives the sliding block 4 to move. The sliding block 4 then drives the inclined block 7 through the housing 6 to move, thus transmitting the bottom plate. This allows the bottom plate to be pushed out from the groove on the bottom surface of the limiting housing 10 and fall directly onto the surface of the conveyor belt 21. Motor 2 drives pulley 18 to rotate, which in turn drives the transmission roller 16 to rotate through pulley 18, belt group 19, and pulley 20. This allows the conveyor belt 21 to transfer the plate to the shearing part. Then, motor 1 reverses, and the inclined surface of the inclined block 7 compresses the spring 8, allowing the inclined block 7 to descend below the plate until the sliding block 4 resets. The inclined block 7 then resets under the action of the spring 8, and the inclined block 7 presses against the bottom plate again. This operation is repeated to achieve automatic feeding.
