[0002] In the field of logistics and handling, chain conveyors or roller conveyors are primarily used for the transfer and transportation of large, heavy-loaded equipment. Most chain and roller conveyors utilize a chain drive system for power transmission. To change the direction of material transport, simply switch the direction of rotation of the drive sprocket to change the chain's direction. Throughout the entire conveying process, the chain must be kept in a tensioned state to prevent slippage and tooth loss.

However, due to the heavy weight of the chain and the long transportation distance, this method is difficult to achieve a better tensioning effect. In particular, when the driving sprocket switches the rotation direction, the chain is prone to tooth jumping, tooth stripping or even breaking, making it difficult to ensure the conveying efficiency of the material conveying system.

[0027] The following combination Figure 1-Figure 3 , through specific embodiments and application scenarios, a chain transmission mechanism and a material conveying system provided by an embodiment of the present invention are described in detail.

[0028] First, as Figure 1 and Figure 2 As shown, the present invention provides a chain transmission mechanism 100, comprising: a driving sprocket 101, two driven sprockets 102 and two anti-slip rollers 103. The driving sprocket 101, the driven sprocket 102 and the anti-slip roller 103 are all used to be installed on a frame 201.

[0029] Two driven sprockets 102 are rotatably mounted at opposite ends of the frame 201. The driving sprocket 101 is located between the two driven sprockets 102. The driving sprocket 101 is installed at a lower height than the two driven sprockets 102. Two anti-slip rollers 103 are located on opposite sides of the driving sprocket 101. The driving sprocket 101 is installed at a higher height than the anti-slip rollers 103. A chain 104 is sequentially mounted on the two anti-slip rollers 103, and the anti-slip rollers 103 are used to tension the chain 104. The driving sprocket 101 and the two driven sprockets 102 are respectively engaged with the chain 104.

[0030] Specifically, if Figure 1 and Figure 2 As shown, the frame 201 includes legs and a workbench, with the legs supported by the workbench. A driving sprocket 101 is rotatably mounted on the bottom surface of the workbench. Two driven sprockets 102 are respectively mounted at both ends of the workbench in the direction in which it extends and are located at the same horizontal height. The installation height of the two driven sprockets 102 is higher than that of the driving sprocket 101. The driving sprocket 101 and the two driven sprockets 102 are respectively engaged with a chain 104. The driving sprocket 101 is used to provide driving force to drive the chain 104 to move, and the two driven sprockets 102 are used to guide the chain 104 to move along the extension direction of the frame 201, thereby transporting the material located above the chain 104 to the next workstation.

[0031] The driving sprocket 101 is located between the two driven sprockets 102. Optionally, the driving sprocket 101 is spaced the same distance from the two driven sprockets 102 to prevent the excessive distance between the driving sprocket 101 and the driven sprocket 102 from interfering with the transmission of the chain 104. One of the anti-slip rollers 103 is rotatably mounted between the driving sprocket 101 and one of the driven sprockets 102, while the other anti-slip roller 103 is rotatably mounted between the driving sprocket 101 and the other driven sprocket 102. The driving sprocket 101, the two anti-slip rollers 103, and the two driven sprockets 102 form a transmission path, and the chain 104 is arranged on the transmission path. Each anti-slip roller 103 is arranged close to the driving sprocket 101 but does not contact each other. The installation height of each anti-slip roller 103 is lower than the driving sprocket 101, and is used to tighten the chain 104 when the driving sprocket 101 switches the rotation direction to prevent the chain 104 from being disengaged from the driving sprocket 101.

[0032] For example, Figure 1As shown, materials need to be transported from the left side of the workbench to the right side of the workbench. In the initial state, the driving sprocket 101 is started to rotate counterclockwise. During the sudden counterclockwise rotation of the driving sprocket 101, the anti-slip roller 103 located on the right side of the driving sprocket 101 can tension the chain segment located at the driving sprocket 101, ensuring that the chain 104 has sufficient tension and does not decouple. When the material conveying direction changes, the rotation direction of the driving sprocket 101 is instantly switched to clockwise. At this time, the anti-slip roller 103 located on the left side of the driving sprocket 101 can tension the chain segment located at the driving sprocket 101, ensuring that the chain 104 has sufficient tension and does not decouple, thus preventing the chain 104 from decoupling and maintaining engagement with the driving sprocket 101. During the frequent switching of the rotation direction of the driving sprocket 101, the chain 104 and the driving sprocket 101 remain in a constant meshing state, thereby improving the conveying efficiency of the material conveying system 200.

[0033] The present utility model provides a chain conveying mechanism 100, in which a driving sprocket 101 is used to drive the chain 104 to move, and two driven sprockets 102 are rotatably installed at both ends of a frame 201, and are used to guide the chain 104 to transmit along the extension direction of the frame 201, so as to convey the material above the chain 104 to the next workstation, and two anti-slip rollers 103 are arranged on opposite sides of the driving sprocket 101, and the installation height of the driving sprocket 101 is higher than the anti-slip rollers 103. When the driving sprocket 101 switches the rotation direction, the anti-slip roller 103 located downstream in the transmission direction of the chain 104 can always tension the chain segment at the driving sprocket 101, ensuring that the chain 104 has sufficient tension and will not be de-toothed. The chain 104 and the driving sprocket 101 always remain in a meshing state, thereby improving the conveying efficiency of the material conveying system 200.

[0034] In some embodiments, as Figure 1 and Figure 2 As shown, the two anti-slip rollers 103 are used to be symmetrically arranged on opposite sides of the driving sprocket 101 in a direction perpendicular to the surface of the frame 201, so as to ensure that each time the driving sprocket 101 changes its rotation direction, the anti-slip roller 103 located downstream in the conveying direction of the chain 104 maintains the same tension on the chain segment at the driving sprocket 101, further ensuring that the chain 104 is not prone to slipping or tooth derailment.

[0035] Furthermore, in some embodiments, Figure 1 and Figure 2 As shown, the chain transmission mechanism 100 further includes a tensioning wheel 105. The tensioning wheel 105 is located between the anti-slip roller 103 on one side of the driving sprocket 101 and the driven sprocket 102. The chain 104 is mounted on the tensioning wheel 105, and the tensioning wheel 105 is movably mounted on the frame 201 to adjust the tension of the chain 104.

[0036] Specifically, if Figure 1 and Figure 2 As shown, the tensioning wheel 105 is arranged on the transmission path between the two adjacent anti-slip rollers 103 and the driven sprocket 102. The chain 104 is mounted on the tensioning wheel 105. As the tensioning wheel 105 moves, the tension of the chain 104 changes. Optionally, the moving direction of the tensioning wheel 105 can be consistent with the conveying direction of the material, or can be perpendicular to the conveying direction of the material. For example, when the moving direction of the tensioning wheel 105 is consistent with the conveying direction of the material, as shown in FIG. Figure 1 As shown, when the tensioning wheel 105 moves in the direction close to the driven sprocket 102 on the left, the tension of the chain 104 decreases. When the tensioning wheel 105 moves in the direction close to the driven sprocket 102 on the right, the tension of the chain 104 increases. For another example, when the movement direction of the tensioning wheel 105 is perpendicular to the conveying direction of the material, when the tensioning wheel 105 moves in the direction close to the anti-slip roller 103, the tension of the chain 104 decreases. When the tensioning wheel 105 moves in the direction close to the driven sprocket 102, the tension of the chain 104 increases. Therefore, the user can control the position of the tensioning wheel 105 relative to the frame 201 according to actual needs, thereby adjusting the tension of the chain 104 and improving the material conveying efficiency.

[0037] Optionally, the tensioning wheel 105 is gearless to ensure the tensioning effect of the tensioning wheel 105 on the chain 104.

[0038] In some embodiments, there are two tensioning wheels 105, one of which is located between the anti-slip roller 103 on one side of the driving sprocket 101 and the driven sprocket 102, and the other is located between the anti-slip roller 103 on the other side of the driving sprocket 101 and the driven sprocket 102. The two tensioning wheels 105 are symmetrically arranged on opposite sides of the driving sprocket 101 along a direction perpendicular to the surface of the frame 201, so that the tension of the chain 104 can be adjusted simultaneously by the two tensioning wheels 105, thereby improving the accuracy of controlling the tension of the chain 104 and ensuring material conveying efficiency. The installation method of the tensioning wheels 105 in this embodiment can be referred to the previous embodiment and will not be repeated here.

[0039] Specifically, the chain transmission mechanism 100 also includes a linear drive mechanism. Figure 1 and Figure 2 As shown, the tensioning pulley 105 includes a connecting shaft 1051 and a wheel body 1052. The chain 104 is mounted on the wheel body 1052. The wheel body 1052 is rotatably mounted on the connecting shaft 1051. The connecting shaft 1051 is inserted through a strip-shaped hole 2011 in the frame 201 and is in transmission connection with a linear drive mechanism. The linear drive mechanism is used to drive the connecting shaft 1051 along the direction of the strip-shaped hole 2011.

[0040] The wheel body 1052 is rotatably sleeved on the connecting shaft 1051 through a bearing. Figure 1 As shown, the frame 201 is provided with a strip-shaped hole 2011. Optionally, the extension direction of the strip-shaped hole 2011 is consistent with the material conveying direction. Furthermore, optionally, the extension direction of the strip-shaped hole 2011 is perpendicular to the material conveying direction. A linear drive mechanism is mounted on the side of the frame 201 facing away from the tensioning wheel 105. The driving end of the linear drive mechanism is in transmission connection with the connecting shaft 1051 to drive the connecting shaft 1051 to move along the extension direction of the strip-shaped hole 2011. The wheel body 1052 moves along with the connecting shaft 1051, thereby adjusting the tension of the chain 104. Optionally, the linear drive mechanism may be a screw drive mechanism.

[0041] Optionally, the anti-slip roller 103 is gearless. Compared to configuring the anti-slip roller 103 as a gear, the gearless design can somewhat reduce the transmission force on the chain 104, ensuring that the anti-slip roller 103 can effectively tension the chain segment at the driving sprocket 101, thereby ensuring the anti-slip roller 103's effectiveness in preventing the chain 104 from being dislodged.

[0042] Furthermore, the gearless wheel surface is provided with anti-skid grooves to increase the friction between the chain 104 and further ensure that the anti-slip roller 103 tightens the chain segment at the driving sprocket 101 to prevent the chain 104 from being de-toothed.

[0043] Second, as Figure 3 As shown, the present invention further provides a material conveying system 200, comprising a frame 201 and two sets of the chain conveyor mechanisms 100 described above. The two sets of chain conveyor mechanisms 100 are symmetrically arranged on opposite sides of the frame 201 along the extension direction of the frame 201. The opposite ends of the material along the conveying direction are respectively mounted on two chains 104, and the two chains 104 cooperate with each other to jointly convey the material to the next workstation.

[0044] Optionally, the material conveying system 200 further includes a dual-axis reducer 202. The dual-axis reducer 202 is in transmission connection with the two driving sprockets 101. Specifically, the dual-axis reducer 202 is fixedly mounted on one side of the frame 201. The two drive ends of the dual-axis reducer 202 are respectively in transmission connection with the two driving sprockets 101 through a gear train, thereby driving the two driving sprockets 101 to rotate simultaneously, ensuring that the two chains 104 maintain a consistent material conveying speed, thereby improving material conveying efficiency.

[0045] like Figure 3As shown, in some embodiments, there are multiple racks 201. Optionally, multiple racks 201 are connected in sequence along the material conveying direction. Two sets of chain conveying mechanisms 100 as described above are installed on opposite sides of each rack 201 along the material conveying direction. The two chain conveying mechanisms 100 on the same side of two adjacent racks 201 are arranged next to each other to extend the material conveying distance and improve the material conveying efficiency. Optionally, two adjacent racks 201 can also be arranged at an angle, for example, vertically, so that the chain conveying mechanisms 100 on the racks 201 can convey the material in different directions, thereby improving the convenience of transportation.

[0046] Since the material conveying system 200 includes the chain conveying mechanism 100, and the specific structure of the chain conveying mechanism 100 refers to the above embodiment, the material conveying system 200 of this embodiment includes all the technical solutions of the above embodiment, and therefore has at least all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here one by one.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
