[0022] This invention provides a mobile roller conveyor and shearing machine. The driving component transmits power to the pushing component via a transmission shaft, causing the pushing component to operate. The pushing component drives the roller conveyor to move along the conveying direction of the sheet metal on the guiding component, moving the roller conveyor away from the shear blade. This increases the gap between the roller conveyor and the shear blade, preventing waste material cut off at the head and tail from getting stuck between the shear blade and the roller conveyor, thus reducing the probability of failure. If waste material cut off at the head and tail gets stuck between the shear blade and the roller conveyor, the roller conveyor can be moved to increase the gap between the shear blade and the roller conveyor, allowing the waste material to fall off. This provides space for inspection and maintenance, quickly eliminates material jamming faults, and ensures the production efficiency of the shearing production line. Attached Figure Description

[0031] It should be noted that the terms "a" and "a plurality of" used in this invention are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0032] To address the problems existing in the aforementioned related technologies, this embodiment provides a moving roller conveyor and a shearing machine.

[0033] like Figure 1 As shown, an embodiment of the present invention provides a moving roller conveyor, including a roller conveyor, a driving assembly, a pushing assembly, a transmission shaft 3, a guiding assembly, and a third base 12;

[0034] The guiding assembly is mounted on the third base 12, the drive shaft 3 is rotatably mounted on the third base 12, and the roller conveyor is slidably mounted on the guiding assembly; one end of the driving assembly is rotatably mounted on the third base 12, and the other end is rotatably mounted on the drive shaft 3; one end of the pushing assembly is rotatably mounted on the drive shaft 3, and the other end is rotatably connected to the roller conveyor; the pushing assembly is used to push the roller conveyor to move along the conveying direction of the sheet metal on the guiding assembly; one end of the roller conveyor is slidably mounted on the frame roller in the shearing machine for conveying the sheet metal, which can be a finished sheet metal blank; one end of the roller conveyor is provided with a shearing blade for shearing the sheet metal, such as... Figure 1 As shown on the left, there is a shear blade on the left side of the roller conveyor. The two shear blades approach each other to cut the board.

[0035] Specifically, the driving component can be a motor driving component, a hydraulic driving component, or a cylinder driving component, etc.; the pushing component can be a crank connecting rod component, a telescopic rod component, or other components capable of driving the roller conveyor; and the guiding component can be a guide rail slider component, a roller component, or other supporting and guiding components, etc.

[0036] In this optional embodiment, the sheet metal is conveyed to the roller conveyor by the shearing machine body. When shearing is required, the shear blade is controlled to descend, and the sheet metal is sheared at the gap between the roller conveyor and the shear blade. If the gap between the roller conveyor and the shear blade is small, the cut sheet metal will get stuck between the shear blade and the roller conveyor. In this case, before processing, the drive component needs to be started. The drive component transmits power to the push component through the transmission shaft 3, causing the push component to work. The push component drives the roller conveyor to move along the conveying direction of the sheet metal on the guide component, so that the roller conveyor moves away from the shear blade, increasing the gap between the roller conveyor and the shear blade. This prevents the waste material cut off at the beginning and end of the cutting from getting stuck between the shear blade and the roller conveyor, reducing the probability of failure. When the waste material cut off at the beginning and end of the cutting is stuck between the shear blade and the roller conveyor, the roller conveyor can also be moved to increase the gap between the shear blade and the roller conveyor, causing the waste material to fall off. This provides space for inspection and maintenance, quickly eliminates the jamming fault, and ensures the production efficiency of the shearing production line. In addition, when the sheet material is thin, if the gap between the roller and the shear blade is large, the edge of the sheared sheet material will turn downwards, causing the sheet material to jam during subsequent transmission. In this case, the drive component transmits power to the push component through the transmission shaft 3. The drive component drives the roller to move closer to the shear blade, reducing the gap between the roller and the shear blade. This allows the edge of the thinner sheet material to remain straight after shearing, improving the shearing quality, enabling the sheet material to be transmitted smoothly, reducing the probability of failure, and ensuring production efficiency.

[0037] Optionally, such as Figure 1As shown, the roller conveyor includes a first roller conveyor frame 1 and a second roller conveyor frame 2, the pushing assembly includes a first pushing assembly and a second pushing assembly, and the guiding assembly includes a first guiding assembly and a second guiding assembly;

[0038] like Figure 2 As shown, multiple rollers are rotatably mounted on the first roller frame 1 and the second roller frame 2 respectively. One end of the first roller frame 1 is slidably mounted on the frame roller in the shearing machine; the other end of the first roller frame 1 is connected to one end of the second roller frame 2.

[0039] The first roller frame 1 is slidably mounted on the first guide assembly; one end of the first push assembly is rotatably mounted on the drive shaft 3, and the other end is rotatably connected to the first roller frame 1.

[0040] The second roller frame 2 is slidably mounted on the second guide assembly; one end of the second push assembly is rotatably mounted on the drive shaft 3, and the other end is rotatably connected to the second roller frame 2.

[0041] In this embodiment, both the first and second pushing components are connected to the transmission shaft 3. Therefore, the drive component can transmit power to the first and second pushing components through the transmission shaft 3, dividing the roller conveyor into a first roller conveyor frame 1 and a second roller conveyor frame 2. This reduces the mass of the roller conveyor, decreases the driving force, and lowers the operating parameters of the drive source in the drive component. The first pushing component drives the first roller conveyor frame 1 to move on the first guide component, and the second pushing component drives the second roller conveyor frame 2 to move on the second guide component. There is a gap between the first roller conveyor frame 1 and the second roller conveyor frame 2, which helps to accommodate the possibility of asynchronous movement or small difference in movement distance between the first roller conveyor frame 1 and the second roller conveyor frame 2. In addition, the other end of the first roller conveyor frame 1 is connected to one end of the second roller conveyor frame 2, and a guide strip is installed on the other end of the first roller conveyor frame 1. A guide strip is also installed on one end of the second roller conveyor frame 2. The ends of the guide strips are chamfered, which helps to guide the plate material to transition between the two roller conveyor frames. Multiple rollers rotatably mounted on the first roller conveyor 1 can be linked by gears or belts, and a motor can be used to drive one of the rollers to rotate, thus driving the other rollers as well; similarly, multiple rollers rotatably mounted on the second roller conveyor 2 can be linked by gears or belts, and a motor can be used to drive one of the rollers to rotate, thus driving the other rollers as well.

[0042] Optionally, such as Figure 1 As shown, the first pushing assembly includes a first connecting rod 4 and a first push-pull rod 8. One end of the first connecting rod 4 is mounted on the transmission shaft 3, and the other end of the first connecting rod 4 is rotatably connected to one end of the first push-pull rod 8. The other end of the first push-pull rod 8 is rotatably mounted on the first roller conveyor frame 1.

[0043] Specifically, the rotation of the drive shaft 3 drives the first connecting rod 4 to rotate. Since the first connecting rod 4 is hinged to the first push-pull rod 8, the first connecting rod 4 drives the first push-pull rod 8 to rotate. When the first push-pull rod 8 rotates, there is a lateral displacement in the horizontal direction, thereby driving the first roller conveyor frame 1 to move horizontally. In addition, on the one hand, because the first roller conveyor frame 1 has a large self-weight, the power of the first push-pull rod 8 in the vertical direction is insufficient to push the first roller conveyor frame 1 to move in the vertical direction. On the other hand, the first roller conveyor frame 1 can be limited on the guide assembly, allowing the first roller conveyor frame 1 to move only in the horizontal direction and not in the vertical direction. This can be achieved by using sliding limit components such as slider guide rail structure and guide bar groove structure.

[0044] Optionally, such as Figure 3 As shown, the second pushing assembly includes a second connecting rod 5 and a second push-pull rod 9. One end of the second connecting rod 5 is mounted on the transmission shaft 3, and the other end of the second connecting rod 5 is rotatably connected to one end of the second push-pull rod 9. A crossbeam 7 is mounted on the second roller frame 2, and the other end of the second push-pull rod 9 is rotatably connected to the crossbeam 7.

[0045] Specifically, the rotation of the drive shaft 3 drives the second connecting rod 5 to rotate. Since the second connecting rod 5 is hinged to the second push-pull rod 9, the second connecting rod 5 drives the second push-pull rod 9 to rotate. When the second push-pull rod 9 rotates, there is a lateral displacement in the horizontal direction, thereby driving the second roller conveyor 2 to move horizontally. On the other hand, because the second roller conveyor 2 has a large self-weight, the power of the second push-pull rod 9 in the vertical direction is insufficient to push the second roller conveyor 2 to move in the vertical direction. On the other hand, the second roller conveyor 2 can be limited to the guide assembly, allowing the second roller conveyor 2 to move only in the horizontal direction and not in the vertical direction. This can be achieved by using sliding limit components such as slider guide rail structure and guide bar groove structure.

[0046] Optionally, such as Figure 1 As shown, the first guide assembly includes a first base 10 and a first guide wheel 14. The plurality of first bases 10 are divided into at least two first base groups. The at least two first base groups are arranged opposite to each other on the third base 12. The first base 10 in each first base group is mounted on the third base 12. The first guide wheel 14 is rotatably mounted on the corresponding first base 10. The first roller frame 1 is slidably mounted on the plurality of first guide wheels 14.

[0047] like Figure 1 As shown, the second guide assembly includes a second base 11 and a second guide wheel 15, as... Figure 4As shown, the plurality of second bases 11 are divided into at least two second base groups, and the at least two second base groups are arranged opposite to each other on the third base 12. The second base 11 in each second base group is mounted on the third base 12, the second guide wheel 15 is rotatably mounted on the corresponding second base 11, and the second roller frame 2 is slidably mounted on the plurality of second guide wheels 15.

[0048] Specifically, such as Figure 1 As shown, multiple first guide wheels 14 are arranged below the first roller conveyor frame 1 (only one is shown in the figure, which can be...). Figure 1 On the left side, multiple first guide wheels 14 are arranged below the first roller conveyor frame 1, and multiple second guide wheels 15 are arranged below the second roller conveyor frame 2 (only one is shown in the figure, but multiple second guide wheels 15 can be added below the second roller conveyor frame 2). Since the first guide wheels 14 and the second guide wheels 15 are rotatably mounted on the base, the friction can be reduced. Therefore, after the first roller conveyor frame 1 is driven by the first push-pull rod 8, it can move relatively easily on the first guide wheels 14. Similarly, after the second roller conveyor frame 2 is driven by the second push-pull rod 9, it can move relatively easily on the second guide wheels 15.

[0049] Optionally, such as Figure 1 and Figure 2 As shown, the drive assembly includes a third link 6 and a telescopic member. One end of the telescopic member is rotatably mounted on the third base 12, and the other end of the telescopic member is rotatably connected to one end of the third link 6. The other end of the third link 6 is mounted on the drive shaft 3.

[0050] Specifically, the telescopic component can be Figure 1 The hydraulic cylinder in the design can be replaced by a pneumatic cylinder, an electric telescopic cylinder, etc., as long as it can push the third link 6. The drive assembly can also be a drive motor, which drives the transmission shaft 3 to rotate, and can also drive the first link 4 and the second link 5 to rotate. Figure 1 In the drive assembly, the telescopic component extends or retracts, causing the third link 6 to rotate, which in turn drives the transmission shaft to rotate. Using a hydraulic cylinder as the drive source, it can provide greater power.

[0051] Optionally, such as Figure 4 As shown, one end of the first guide wheel 14 and one end of the second guide wheel 15 are respectively provided with flanges 18;

[0052] The flange 18 at one end of the first guide wheel 14 is located inside the first roller frame 1. The flanges 18 on the two opposing first guide wheels 14 are used to restrict the first roller frame 1 to prevent the first roller frame 1 from moving along the axial direction of the first guide wheel 14.

[0053] The flange 18 at one end of the second guide wheel 15 is located inside the second roller frame 2. The flanges 18 on the two opposing second guide wheels 15 are used to restrict the second roller frame 2 to prevent the second roller frame 2 from moving along the axial direction of the second guide wheel 15.

[0054] Specifically, the flanges 18 on both the first guide wheel 14 and the second guide wheel 15 are arranged inside the roller conveyor, for example... Figure 4 In the middle, the flanges 18 on the two oppositely arranged second guide wheels 15 are set close to the center line. The distance between the flanges 18 and the center line is less than the distance between the inner edge of the second roller frame 2 and the center line. This can restrict the second roller frame 2 from moving axially in the second guide wheels 15, reduce the shaking of the second roller frame 2, and make the first roller frame 1 and the second roller frame 2 well connected, avoid misalignment of the first roller frame 1 and the second roller frame 2, and ensure that the plate can be smoothly transferred from the first roller frame 1 to the second roller frame 2.

[0055] Optionally, such as Figure 1 As shown, the moving roller conveyor also includes a swing arm 16 and a limiter 17. One end of the swing arm 16 is installed on one end of the drive shaft 3, and the limiter 17 is installed on the third base 12. The installation position of the limiter 17 is located on the movement trajectory of the other end of the swing arm 16.

[0056] Specifically, when the drive shaft 3 rotates, it drives the swing arm 16 to rotate. As the swing arm 16 rotates, the other end of the swing arm 16 contacts the limiter 17, triggering the limiter 17. The limiter 17 sends a signal to the control center, which can control the telescopic component in the drive assembly to stop working, thereby preventing excessive displacement of the first roller frame 1 and the second roller frame 2.

[0057] like Figure 1 As shown, an embodiment of the present invention provides a shearing machine, including the aforementioned movable roller conveyor and shear blade;

[0058] One end of the movable roller conveyor is slidably mounted on the frame roller in the shearing machine for conveying the sheet metal; one end of the movable roller conveyor is provided with a shearing blade, which is mounted on the frame in the shearing machine.

[0059] Specifically, the shearing machine body can be set in Figure 1 On the left side of the moving roller conveyor, Figure 1 A shearing blade is installed in the upper left corner of the moving roller conveyor. When the sheet material is conveyed to the gap between the moving roller conveyor and the shearing blade, it can be sheared to segment the sheet material. The moving roller conveyor can flexibly adjust the size of the gap between the moving roller conveyor and the shearing blade to adapt to sheet materials of various thicknesses, reduce the failure rate, and improve production efficiency.

[0060] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
