[0002] Currently, traditional shearing equipment on sheet and board production lines cannot stop operating during shearing. Furthermore, the limitations of sheets and boards prevent them from being stored, so the shearing machine must follow the shearing process. The matching accuracy between the follow-up speed of the shearing machine and the moving speed of the sheet or board is not high, resulting in large errors in the shearing length and easy warping of products. This causes a great waste of labor and products, increases production and labor costs, reduces production efficiency, and thus fails to meet customer needs. Summary of the Invention

The conveying assembly includes a first conveying frame and a second conveying frame rotatably connected to each other, and a plurality of conveying rollers rotatably mounted on the first conveying frame and the second conveying frame. The first conveying frame is located in front of the second conveying frame. The plurality of conveying rollers are arranged at intervals from front to back on the first conveying frame and the second conveying frame, and all extend in the left-right direction. A lifting device is also provided on the transition frame. The lifting device is driven by one of the first conveying frame and the second conveying frame. Under the drive of the lifting device, the conveying assembly has a lifted state in which the junction of the first conveying frame and the second conveying frame is arched upwards, and a horizontal state in which the first conveying frame and the second conveying frame are level.

[0006] In the above technical solution, a further preferred embodiment is that the first conveyor frame includes a pair of first support plates arranged opposite to each other on the left and right and at least one first cross brace connected between the pair of first support plates. The front end of each of the first support plates is rotatably and slidably connected to the first support column, and its rear end is hinged to the second conveyor frame.

[0007] In the above technical solution, it is further preferred that the front end of each of the first support plates is provided with a waist-shaped hole, and a limiting shaft that cooperates with the waist-shaped hole is installed on the first support column.

[0010] In the above technical solution, a further preferred embodiment is that the conveying mechanism further includes a driving device, which is connected to one of the conveying rollers to drive the corresponding conveying roller to rotate around its own axis.

[0011] In the above technical solution, it is further preferred that a conveyor belt pulley is coaxially mounted at one end of each of the conveying rollers, the conveyor belt pulleys of the plurality of conveying rollers are arranged on the same side, and a conveyor belt connects the pulley of each of the conveying rollers to the conveyor belt pulley of the adjacent conveying roller on the rear side.

[0021] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0022] This application provides an online shearing machine, which is arranged in the sheet and board production line and can perform transverse cutting of sheets and boards online without requiring the sheet and board production line to be stopped.

[0023] like Figure 1 As shown, the online shearing machine 100 includes a shearing mechanism 10 capable of transversely cutting products and a conveying mechanism 20. The conveying mechanism 20 is arranged in front of the shearing mechanism 10 to continuously convey sheets and plates to the shearing mechanism 10 from front to back.

[0024] like Figure 1 , 3 As shown in Figure 5, the conveying mechanism 20 includes a transition frame 1 and a conveying assembly 2 mounted on the transition frame 1. The conveying assembly 2 includes a first conveying frame 21 and a second conveying frame 22 rotatably connected to each other, and a plurality of conveying rollers 23 rotatably mounted on the first conveying frame 21 and the second conveying frame 22. The first conveying frame 21 is located in front of the second conveying frame 22. The plurality of conveying rollers 23 are arranged at intervals from front to back on the first conveying frame 21 and the second conveying frame 22, and all extend in the left-right direction. Bearing assemblies are installed on both the first conveying frame 21 and the second conveying frame 22, so that each conveying roller 23 can be rotatably mounted on the first conveying frame 21 and the second conveying frame 22 around its own axis, thereby reducing the friction force when the product moves on the conveying mechanism 20 and improving the conveying efficiency.

[0025] The rear end of the transition frame 1 is connected to the shearing mechanism 10. The transition frame 1 includes a connecting beam 11 extending in the front-rear direction, a first support column 12 installed at the front end of the connecting beam 11, and a second support column 13 installed at the rear end of the connecting beam 11. The first support column 12 and the second support column 13 are parallel to each other and both extend in the vertical direction. The first support column 12 supports the connecting beam 11 on the ground, and the second support column 13 is installed on the connecting beam 11 and cooperates with the first support column 12 to support the conveying mechanism 20 on the front side of the shearing mechanism 10.

[0026] like Figure 1-5 As shown, the first conveyor frame 21 includes a pair of first support plates 211 arranged opposite each other and at least one first cross brace 212 connected between the pair of first support plates 211. The front end of each first support plate 211 is rotatably and slidably connected to the top end of the first support column 12, and its rear end is hinged to the second conveyor frame 22. The conveyor roller 23 mounted on the first conveyor frame 21 is rotatably supported between the pair of first support plates 211, and at least one first cross brace 212 is used to strengthen the support strength of the first conveyor frame 21.

[0027] like Figure 2 , 4As shown, each of the first support plates 211 has a waist-shaped hole 213 at its front end. A limiting shaft 14 that cooperates with the waist-shaped hole 213 is installed on the first support column 12. The waist-shaped hole 213 has a first limiting part 2131 and a second limiting part 2132 located behind the first limiting part 2131. During the rotation of the first support plate 211, the limiting shaft 14 can rotate within the waist-shaped hole 213 and slide between the first limiting part 2131 and the second limiting part 2132.

[0028] like Figure 1-5 As shown, the second conveyor frame 22 includes a pair of second support plates 221 arranged opposite each other and at least one second cross brace 222 connected between the pair of second support plates 221. The front end of each second support plate 221 is hinged to the rear end of the corresponding first support plate 211, and its rear end is hinged to the second support column 13. The conveyor roller 23 mounted on the second conveyor frame 22 is rotatably mounted between the pair of second support plates 221, and at least one second cross brace 222 is used to strengthen the support strength of the second conveyor frame 22.

[0029] A lifting device 30 is also provided on the transition frame 1. The lifting device 30 is drivenly connected to one of the first conveyor frame 21 and the second conveyor frame 22. In this embodiment, the lifting device 30 is drivenly connected to the second conveyor frame 22 and is connected near the front end of the second conveyor frame 22. The lifting device 30 is a cylinder. When the air rod of the lifting device 30 extends, the front end of the second conveyor frame 22 is raised, and the rear end of the first conveyor frame 21, which is hinged to the front end of the second conveyor frame 22, is also raised. At this time, the rear end of the first conveyor frame 21 and the front end of the second conveyor frame 22 are located above the front end of the first conveyor frame 21 and the rear end of the second conveyor frame 22. The entire conveying assembly 2 is arched like a bridge. The arched conveying assembly 2 increases the moving distance of the product between the first support column 12 and the second support column 13.

[0030] Driven by the lifting device 30, the conveying assembly 2 has a lifted state in which the junction of the first conveying frame 21 and the second conveying frame 22 is arched upwards, and a horizontal state in which the first conveying frame 21 and the second conveying frame 22 are level.

[0031] When the shearing mechanism 10 shears the product, the middle of the conveying component 2 arches upward to a raised state, gradually increasing the longitudinal movement length of the product, thereby temporarily storing the products continuously conveyed upstream and realizing online shearing operation without stopping the machine. After the shearing mechanism 10 finishes shearing, the lifting device 30 drives the front end of the second conveying frame 22 to descend, causing the first conveying frame 21 and the second conveying frame 22 to rotate to a horizontal state where they are level, and the product is released backward for the shearing mechanism 10 to perform the next shearing. When the conveying component 2 is in the raised state, the limiting shaft 14 is close to the first limiting part 2131; when the conveying component 2 is in the horizontal state, the limiting shaft 14 is close to the second limiting part 2132, causing the portion of the first conveying frame 21 between the first support column 12 and the second support column 13 to be reduced. The length change of the first conveying frame 21 between the first support column 12 and the second support column 13 adapts to the length difference of the conveying component 2 when it is arched and horizontal.

[0032] At least one adjusting top shaft 15 is installed on the first support column 12 or the second support column 13, and the at least one adjusting top shaft 15 is located below the first support plate 211 and the second support plate 221. In this embodiment, the adjusting top shaft 15 is installed on the second support column 13. When the conveying assembly 2 is in a horizontal state, the adjusting top shaft 15 is pressed against the bottom of the second support plate 221 to support the first conveying frame 21 and the second conveying frame 22 in a level horizontal state.

[0033] like Figure 1 , 5 As shown in Figure 6, the conveying mechanism 20 also includes a drive device 3, which is connected to one of the conveying rollers 23 to drive the corresponding conveying roller 23 to rotate around its own axis. A conveyor pulley 24 is coaxially mounted at one end of each conveying roller 23. The conveyor pulleys 24 of several conveying rollers 23 are arranged on the same side, and a conveyor belt 25 connects each conveyor pulley 24 of a conveying roller 23 to the conveyor pulley 24 of the adjacent conveying roller 23 on its rear side. When the drive device 3 drives the corresponding conveying roller 23 to rotate, the other conveying rollers 23 are driven to rotate through the transmission cooperation of the conveyor pulley 24 and the conveyor belt 25, thereby realizing the active conveying of products from front to back by the conveying mechanism 20. The rotational speed of the conveying rollers 23 driven by the drive device 3 is consistent with the overall line speed of the sheet metal production line.

[0034] The online shearing machine 100 also includes a meter counter (not shown in the figure) installed on the shearing mechanism 10. The meter counter is signal-connected to the shearing mechanism 10 and the lifting device 30. The shearing mechanism 10 shears products of a specified length under the signal of the meter counter. The lifting device 30 is synchronously raised and lowered under the signal of the meter counter to match the shearing speed of the shearing mechanism 10.

[0035] The drive unit 3, the meter counter, the shearing mechanism 10, and the lifting device 30 are all controlled by the control device of the sheet and board production line to match the overall speed of the sheet and board production line and cooperate with each other to complete the online shearing operation.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
