[0038] As Figure 1 and Figure 2 shown, an embodiment of the present application provides a conveying device 100, which is mainly applied to a steel bar straightening and cutting device 1000. The conveying device 100 includes a frame 110, a driving mechanism and a plurality of pressing mechanisms.

[0039] The driving mechanism includes a rotary driving member 121, a driving shaft 122 and a plurality of first conveying wheels 123. The rotary driving member 121 is arranged on the frame 110. The driving shaft 122 is rotatably arranged on the frame 110 and is connected to the rotating end of the rotary driving member 121. A plurality of the first conveying wheels 123 are fixedly connected to the driving shaft 122 at intervals along the axial direction of the driving shaft 122.

[0040] A plurality of the pressing mechanisms are arranged on the frame 110 at intervals along the axial direction of the driving shaft 122. The pressing mechanism includes a linear driving member 131, a connecting rod assembly 132 and a first pressing wheel 133. The connecting rod assembly 132 is connected to the telescopic end of the linear driving member 131. The first pressing wheel 133 is rotatably mounted on the connecting rod assembly 132. The linear driving member 131 is used to drive the connecting rod assembly 132 to drive the first pressing wheel 133 to approach or move away from the first conveying wheel 123.

[0041] The conveying device 100 provided by the embodiments of the present application drives the rotating end of the rotary driving member 121 disposed on the frame 110 to be connected to the driving shaft 122, so as to drive the driving shaft 122 to rotate on the frame 110, thereby driving the first conveying wheel 123 fixedly connected to the driving shaft 122 to rotate synchronously. By connecting the telescopic end of the linear driving member 131 to the link assembly 132, the link assembly 132 is driven to drive the first pressing wheel 133 rotatably mounted on the link assembly 132 to approach or move away from the first conveying wheel 123. When the first pressing wheel 133 approaches the first conveying wheel 123, the steel bar can be clamped, so that the steel bar is in close contact with the first conveying wheel 123 and the first pressing wheel 133 respectively. Thus, under the rotation of the first conveying wheel 123, the steel bar is driven to move linearly, realizing the conveying of the steel bar; when the first pressing wheel 133 moves away from the first conveying wheel 123, the steel bar can be relaxed, thereby stopping the conveying of the steel bar.

[0042] Meanwhile, by setting the number of the first conveying wheels 123 and the pressing mechanisms to be multiple, and arranging the multiple first conveying wheels 123 and the multiple pressing mechanisms at intervals along the axial direction of the driving shaft 122, the conveying device 100 can convey multiple coils of steel bars with the same or different diameter specifications simultaneously, saving time and effort and effectively improving the production efficiency.

[0043] Exemplarily, the rotary driving member 121 can be a servo driving motor, and the linear driving member 131 can be a cylinder or a hydraulic cylinder.

[0044] As Figure 1 and Figure 2 shown, in an embodiment of the present application, the conveying device 100 further includes a transmission mechanism. The transmission mechanism includes a transmission shaft 141, a plurality of second conveying wheels 142 and a synchronous pulley 143. The transmission shaft 141 is rotatably disposed on the frame 110 and is spaced from the driving shaft 122 along the conveying direction. The plurality of second conveying wheels 142 are fixedly connected to the transmission shaft 141 at intervals along the axial direction of the transmission shaft 141. The synchronous pulley 143 is respectively connected to the driving shaft 122 and the transmission shaft 141. The pressing mechanism further includes a second pressing wheel 134. The second pressing wheel 134 is rotatably mounted on the link assembly 132 and is spaced from the first pressing wheel 133 along the conveying direction. The linear driving member 131 is used to drive the link assembly 132 to drive the second pressing wheel 134 to approach or move away from the second conveying wheel 142.

[0045] In this embodiment, by connecting the synchronous belt pulley 143 to the drive shaft 122 and the transmission shaft 141 respectively, the transmission shaft 141 can rotate synchronously with the drive shaft 122, so that a plurality of second conveying wheels 142 fixedly connected at intervals along the axial direction of the transmission shaft 141 can rotate synchronously with the transmission shaft 141. By connecting the telescopic end of the linear drive member 131 to the link assembly 132 to drive the link assembly 132 and drive the second pressing wheel 134 rotatably mounted on the link assembly 132 to approach or move away from the second conveying wheel 142, when the second pressing wheel 134 approaches the second conveying wheel 142, it can clamp the steel bar, so that the steel bar is in close contact with the second conveying wheel 142 and the second pressing wheel 134 respectively. Thus, under the rotation action of the second conveying wheel 142, the steel bar is driven to move linearly, realizing the conveying of the steel bar, effectively improving the conveying effect and conveying stability of the steel bar; when the second pressing wheel 134 moves away from the second conveying wheel 142, it can loosen the steel bar, thus stopping the conveying of the steel bar.

[0046] As Figure 1 and Figure 2 shown, in an embodiment of the present application, the link assembly 132 includes a lever 1321 and a first link 1322. The lever 1321 is rotatably connected to the frame 110. One end of the lever 1321 is connected to the telescopic end of the linear drive member 131, and the other end is connected to the first link 1322. The first pressing wheel 133 is rotatably mounted at the end of the first link 1322 away from the lever 1321.

[0047] In this embodiment, by providing a lever 1321 rotatably connected to the frame 110 and connecting the two ends of the lever 1321 to the telescopic end of the linear drive member 131 and the first link 1322 respectively, the linear drive member 131 can drive the first pressing wheel 133 to press the steel bar by using the lever 1321 principle, so that the linear drive member 131 with a small driving force can also ensure the pressing effect on the steel bar, thus facilitating the expansion of the model selection range of the linear drive member 131.

[0048] As Figure 1 and Figure 2 shown, in the above embodiment of the present application, the link assembly 132 further includes a second link 1323. One end of the second link 1323 is rotatably connected to the frame 110, and the other end is rotatably connected to the end of the first link 1322 away from the lever 1321.

[0049] In this embodiment, by providing a second connecting rod 1323 that is rotatably connected to the frame 110 and the end of the first connecting rod 1322 away from the lever 1321, the first connecting rod 1322 can be connected to the frame 110 through the second connecting rod 1323, thereby improving the structural stability and reliability of the connecting rod assembly 132.

[0050] In the above embodiment of the present application, the length between the connection point of the lever 1321 and the frame 110 and the end of the lever 1321 close to the first connecting rod 1322 is L1, and the length between the connection point of the lever 1321 and the frame 110 and the end of the lever 1321 close to the linear drive member 131 is L2, satisfying the relationship: L1 / L2 = 1 / 5. Thus, the power arm is much larger than the resistance arm, so that the linear drive member 131 with a smaller driving force can also ensure the pressing effect on the steel bar, which is beneficial to expanding the range of model selection of the linear drive member 131.

[0051] As Figure 1 and Figure 2 shown, in an embodiment of the present application, the drive mechanism further includes a coupling 124, and the drive shaft 122 is connected to the rotating end of the rotating drive member 121 through the coupling 124. Thus, the drive shaft 122 can rotate stably synchronously with the rotating end of the rotating drive member 121, ensuring the rotational stability and reliability of the drive shaft 122.

[0052] As Figure 1 and Figure 2 shown, in an embodiment of the present application, a plurality of first bearing seats 111 are provided on the frame 110, and the plurality of first bearing seats 111 are arranged at intervals along the axial direction of the drive shaft 122, and the drive shaft 122 is rotatably installed on the plurality of first bearing seats 111. Thus, the drive shaft 122 can rotate smoothly on the frame 110, thereby ensuring the conveying effect of the steel bar.

[0053] As Figure 1 and Figure 2 shown, in the above embodiment of the present application, a plurality of second bearing seats 112 are provided on the frame 110, and the plurality of second bearing seats 112 are arranged at intervals along the axial direction of the transmission shaft 141, and the transmission shaft 141 is rotatably installed on the plurality of second bearing seats 112. Thus, the transmission shaft 141 can rotate smoothly on the frame 110, thereby ensuring the conveying effect of the steel bar.

[0054] In an embodiment of the present application, the conveying device 100 further includes an encoder and a controller, and the controller is electrically connected to the encoder and the rotating drive member 121 respectively, and is also electrically connected to the linear drive member 131.

[0055] In this embodiment, the controller can control the start and stop of the rotary driving member 121 and the linear driving member 131 according to the number-of-turns signal fed back by the encoder, so as to control the conveying length of the steel bars, which is beneficial for the straightening device and the cutting device of the subsequent steel bar straightening and cutting equipment 1000 to process the coiled steel bars into straight steel bars of a preset length.

[0056] Exemplarily, the encoder can be an incremental encoder or an absolute encoder, and the controller can be a programmable logic controller.

[0057] As Figure 3 shown, the embodiment of the present application further provides a steel bar straightening and cutting equipment 1000, including the conveying device 100 described in the above embodiment.

[0058] The steel bar straightening and cutting equipment 1000 has the conveying device 100 in any of the above embodiments, so it has all the beneficial effects of the conveying device 100, which will not be elaborated here one by one.
