The features defined as "first" and "second" are used to distinguish the feature names, rather than having special meanings. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] like Figure 1 As shown, the embodiment of the present application provides a conveyor belt system, which includes a main conveying unit 101 and an auxiliary conveying unit 401. Both the main conveying unit 101 and the auxiliary conveying unit 401 can provide power for conveying materials, and the auxiliary conveying unit 401 is used to expand the width of the main conveying unit 101, and the distance between the auxiliary conveying unit 401 and the main conveying unit 101 can be adjusted to ensure that the conveyor belt system can stably convey materials of different widths.

[0033] Among them, the lengths of the main conveying unit 101 and the auxiliary conveying unit 401 can be adjusted to increase or decrease the effective conveying lengths of the main conveying unit 101 and the auxiliary conveying unit 401, so that the conveyor belt system can adapt to different conveying scenarios and improve the versatility of the conveyor belt system.

[0034] like Figure 2As shown, in some examples, the main conveying unit 101 includes a main conveyor belt body 102 and a main fixed bracket 103, and the conveyor belt system includes a frame, and the main fixed bracket 103 is fixedly connected to the frame to ensure that the position of the main fixed bracket 103 is stable.

[0035] The main conveyor belt body 102 is wound around the main fixed bracket 103, and the top surface of the main fixed bracket 103 is used to support the main conveyor belt body 102. It can be understood that the part of the main conveyor belt body 102 above the main fixed bracket 103 is used to place and transport materials. In order to ensure the effective conveying length of the main conveying unit 101, the main fixed bracket 103 also has a certain length.

[0036] Specifically, a main fixed roller group is provided on the main fixed bracket 103 , and the conveyor belt body is wound around the main fixed bracket 103 through the main fixed roller group.

[0037] like Figure 3 As shown, in some examples, the main fixed roller group includes a first fixed end roller 201, a plurality of first adjustment rollers 202 and a first turning roller 203. It can be understood that the first fixed end roller 201, the plurality of first adjustment rollers 202 and the first turning roller 203 can all rotate on the main fixed bracket 103. The first fixed end roller 201 unilaterally limits the effective conveying length of the main conveying unit 101, and the heights of each first adjustment roller 202 and the first turning roller 203 are both less than the height of the first fixed end roller 201. After the main conveyor belt body 102 bypasses the first fixed end roller 201, it continues to bypass each first adjustment roller 202 to reduce the height of the main conveyor belt body 102; after the height is reduced, the main conveyor belt body 102 bypasses the first turning roller 203 and changes the extension direction at the first turning roller 203.

[0038] The extension direction of the main conveyor belt body 102 before passing through the first turning roller 203 is opposite to the extension direction of the main conveyor belt body 102 after passing through the first turning roller 203. The first turning roller 203 allows the main conveyor belt body 102 to initially form a stacked arrangement.

[0039] In some examples, in order to ensure that the first fixed-end roller 201, the first adjustment rollers 202 and the first turning roller 203 do not affect the movement of the main conveyor belt body 102 while supporting the main conveyor belt body 102, the first fixed-end roller 201, the first adjustment rollers 202 and the first turning roller 203 are all rotatably connected to the main fixed bracket 103.

[0040] Furthermore, the first fixed end roller 201 is rotatably connected to the end of the main fixed bracket 103, and a plurality of first extension parts are provided on the main fixed bracket 103, each first extension part extends to the bottom of the main fixed bracket 103, and each first adjustment roller 202 and the first steering roller 203 are rotatably connected to each first extension part.

[0041] The main conveying unit 101 further includes a main movable support 104, which together with the main fixed support 103 supports the main conveying belt body 102, and the lengths of the main movable support 104 and the main fixed support 103 determine the effective conveying length of the main conveying unit 101. The main movable support 104 is movably connected to the main fixed support 103, and when the main movable support 104 moves on the main fixed support 103, the length of the main movable support 104 extending from the main fixed support 103 changes, thereby changing the effective conveying length of the main conveying unit 101.

[0042] It is understandable that the main conveyor belt body 102 also needs to bypass the main movable support 104, wherein the main movable support 104 is provided with a main movable roller group, and the main conveyor belt body 102 is wound around the main movable support 104 in a manner of bypassing the main movable roller group. Therefore, the main conveyor belt body 102 is wound around the main fixed support 103 and the main movable support 104.

[0043] Specifically, the main conveyor belt body 102 continues to bypass the main movable roller set after bypassing the first turning roller 203, and the main movable roller set further enables the main conveyor belt body 102 to be stacked. When the length of the whole formed by the main movable bracket 104 and the main fixed bracket 103 increases, the length of the stacked part of the main conveyor belt body 102 decreases, and the main conveyor belt body 102 can cover the main movable bracket 104 and the main fixed bracket 103 with a larger length to cooperate with the movement of the main movable bracket 104. Similarly, when the length of the whole formed by the main movable bracket 104 and the main fixed bracket 103 decreases, the length of the stacked part of the main conveyor belt body 102 increases, and the main conveyor belt body 102 can cover the main movable bracket 104 and the main fixed bracket 103 with a smaller length to cooperate with the movement of the main movable bracket 104.

[0044] like Figure 3As shown, in some examples, the main movable roller group includes a first movable end roller 204 and a second turning roller 205. It can be understood that the first movable end roller 204 and the second turning roller 205 can both rotate on the main movable bracket 104. The first movable end roller 204 unilaterally defines the effective conveying length of the main conveying unit 101, and the first fixed end roller 201 and the first movable end roller 204 jointly define the effective conveying length of the main conveying unit 101. After the main conveyor belt body 102 bypasses the first movable end roller 204, it continues to bypass the second turning roller 205, thereby changing the extension direction at the second turning roller 205.

[0045] The extension direction of the main conveyor belt body 102 that has not passed through the second turning roller 205 is opposite to the extension direction of the main conveyor belt body 102 that has passed through the second turning roller 205, and the second turning roller 205 further stacks the main conveyor belt body 102. It can be understood that the main conveyor belt body 102 undergoes two changes in extension direction to form a stacked portion.

[0046] In some examples, the main movable bracket 104 is slidably connected to the main fixed bracket 103 , and the main movable bracket 104 includes an upper support portion 206 and a lower support portion 207 , which are interconnected at the end of the main movable bracket 104 to form a whole.

[0047] The upper support portion 206 is located at the top of the main fixed bracket 103, and there are corresponding recessed parts and protruding parts at the top of the upper support portion 206 and the main fixed bracket 103, and the protruding part is embedded in the recessed part to form a sliding connection. The lower support portion 207 is located at the bottom of the main fixed bracket 103, and there is a slide rail and slider mechanism between the lower support portion 207 and the bottom of the main fixed bracket 103, and the slider can move along the slide rail to form a sliding connection.

[0048] In some examples, the first movable end roller 204 is rotatably connected to the ends of the upper support portion 206 and the lower support portion 207, a second extension portion is provided on the main movable bracket 104, the second extension portion extends toward the bottom of the main movable bracket 104, and the second turning roller 205 is rotatably connected to the second extension portion.

[0049] In some examples, in order to drive the main movable support 104 to move relative to the main fixed support 103 , a first driving structure is provided on the main movable support 104 , and the first driving structure may adopt any mechanism that outputs linear motion.

[0050] Specifically, the first driving structure adopts a motor and a screw. The motor is connected to the main fixed bracket 103, the output end of the motor is connected to the screw, and a nut structure engaged with the screw is provided on the main movable bracket 104. The motor drives the screw to rotate, so that the nut structure drives the main movable bracket 104 to move.

[0051] In some examples, in order to drive the main fixed roller group and the main movable roller group to rotate, a second driving structure 301 is further provided on the main conveying unit 101, and the second driving structure 301 can output rotational motion. Specifically, the second driving structure 301 uses a motor, and the second driving structure 301 is connected to the main fixed bracket 103, and transmits the torque to a first adjustment roller 202 through a corresponding transmission mechanism, and the first adjustment roller 202 then transmits the torque to the main conveyor belt body 102. Under the movement of the main conveyor belt body 102, the main fixed roller group and the main movable roller group rotate synchronously.

[0052] like Figure 6 That is, as shown in the partial method FIG1, in some examples, the height of the main conveying unit 101 can be adjusted. A support platform 302 is provided on the main fixed support 103, the support platform 302 is at the bottom of the main fixed support 103, and the support platform 302 is connected to the third driving structure 303, and the third driving structure 303 can drive the support platform 302 to move in the vertical direction to raise or lower the height of the main conveying unit 101, that is, to change the height of the conveying path.

[0053] Specifically, the third driving structure 303 uses a motor and a transmission mechanism that converts rotational motion into linear motion, and the motor can drive the supporting platform 302 to move in the vertical direction through the transmission mechanism.

[0054] like Figure 4 , Figure 5 As shown, the conveyor belt system further includes an auxiliary conveyor unit 401 , which is disposed on both sides of the main conveyor unit 101 to expand the width of the conveyor belt system and improve the versatility of the conveyor belt system.

[0055] In some examples, similar to the main conveying unit 101, the auxiliary conveying unit 401 includes an auxiliary conveying belt body and an auxiliary fixing bracket, and the auxiliary fixing bracket is fixedly connected to the frame. The auxiliary conveying belt body is wound around the auxiliary fixing bracket, and the top surface of the auxiliary fixing bracket is used to support the auxiliary conveying belt body.

[0056] Specifically, the auxiliary fixing bracket is provided with an auxiliary fixing roller set, and the conveyor belt body is wound around the auxiliary fixing bracket through the auxiliary fixing roller set, and the auxiliary fixing roller set enables the auxiliary conveyor belt body to initially form a stacked arrangement.

[0057] The auxiliary conveying unit 401 further includes an auxiliary movable bracket, which together with the auxiliary fixed bracket supports the auxiliary conveying belt body, and the length of the auxiliary movable bracket and the auxiliary fixed bracket determines the effective conveying length of the auxiliary conveying unit 401. The auxiliary movable bracket is provided with an auxiliary movable roller group, and the auxiliary movable bracket is movably connected with the auxiliary fixed bracket. When the auxiliary movable bracket moves on the auxiliary fixed bracket, the length of the auxiliary movable bracket extending from the auxiliary fixed bracket changes, thereby changing the effective conveying length of the auxiliary conveying unit 401.

[0058] Specifically, the auxiliary conveyor belt body undergoes two changes in extension direction to form a stacked portion. When the length of the entirety formed by the auxiliary movable bracket and the auxiliary fixed bracket increases, the length of the stacked portion of the auxiliary conveyor belt body decreases, and the auxiliary conveyor belt body can cover the auxiliary movable bracket and the auxiliary fixed bracket with a larger length to match the movement of the auxiliary movable bracket. Similarly, when the length of the entirety formed by the auxiliary movable bracket and the auxiliary fixed bracket decreases, the length of the stacked portion of the auxiliary conveyor belt body increases, and the auxiliary conveyor belt body can cover the auxiliary movable bracket and the auxiliary fixed bracket with a smaller length to match the movement of the auxiliary movable bracket.

[0059] In some examples, in order to drive the secondary movable support to move relative to the secondary fixed support, a fourth driving structure is provided on the secondary movable support, and the fourth driving structure can adopt any mechanism that outputs linear motion.

[0060] In some examples, in order to drive the auxiliary fixed roller group and the auxiliary movable roller group to rotate, a fifth driving structure is further provided on the auxiliary conveying unit 401, and the fifth driving structure can output rotational motion. The fifth driving structure drives any one of the rollers in the auxiliary fixed roller group and the auxiliary movable roller group to rotate to ensure that all rollers rotate together.

[0061] In some examples, the height of the auxiliary conveying unit 401 can be adjusted. A supporting platform is also provided on the auxiliary fixed support, the supporting platform is at the bottom of the auxiliary fixed support, and the supporting platform is connected to the sixth driving structure 402, and the sixth driving structure 402 can drive the supporting platform to move in the vertical direction to raise or lower the height of the auxiliary conveying unit 401.

[0062] like Figure 7 That is, as shown in the partially enlarged view II, in some examples, the auxiliary conveying unit 401 and the main conveying unit 101 are arranged in parallel, and the interval between the auxiliary conveying unit 401 and the main conveying unit 101 can be adjusted, thereby changing the overall width of the conveyor belt system.

[0063] Among them, a seventh driving structure 403 is arranged on the auxiliary conveying unit 401. Specifically, the seventh driving structure 403 includes a motor, a rack arranged on the frame and a gear arranged on the auxiliary conveying unit 401. The motor drives the gear to rotate and converts the rotational motion into movement of the auxiliary conveying unit 401 through the rack.

[0065] The above describes the implementation methods of the present application in detail in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
