[0029] The present application will be further described in detail below in conjunction with the drawings:

[0030] Reference Figures 1-5 The belt conveying device, like the differential belt conveyor applied in the existing logistics industry, comprises a rack 1, a conveying assembly 2 and a driving device installed on the rack 1. The rack 1 is a support structure, the conveying assembly 2 is used to convey materials or goods in cooperation with the rack 1, and the driving device is connected to the conveying assembly and can drive the conveying assembly to move. The conveying assembly 2 comprises a plurality of roller sets 21 connected to the rack 1 and a transmission belt 22 surrounding the plurality of roller sets 21. Some of the plurality of roller sets 21 are used to drive the roller sets 21 to guide the movement of the transmission belt 22, some are used to abut the transmission belt 22, and some are used to correct the transmission belt 22. The specific function details are not described one by one.

[0031] In operation, the driving device can provide power for the conveying assembly 2 to make the transmission belt 22 move along the plurality of roller sets 21 in a predetermined direction, thereby driving the materials and goods on the rack 1 to move.

[0032] Compared with the prior art, one of the improvements of the present application is that an internal driving design is adopted, that is, the driving device of the belt conveying device directly adopts an electric roller 3 connected to the rack 1 for the transmission belt 22 to surround and rotate to guide the movement of the transmission belt 22. Compared with the traditional external driving design “configuring an electric motor and a speed reducer at the bottom and side of the differential belt conveyor to directly or indirectly drive the roller set 21 to rotate to drive the transmission belt 22 to move”, the present application directly adopts the electric roller 3 to drive the transmission belt 22 to move. Since the electric roller 3 integrates the electric motor and the speed reducer, it is directly installed on the roller of the belt conveyor, without the need for additional accommodation space, which significantly reduces the volume and weight of the equipment, makes the layout more compact and flexible when the present application is applied to a multi-layer line layout, improves the space utilization, reduces the equipment cost and floor area, in addition, the electric roller 3 does not need additional transmission mechanisms such as belts and chains to directly drive the transmission belt 22 to move, which reduces the energy loss in the transmission process, has higher transmission efficiency, and makes the operation of the differential belt conveyor more efficient and energy-saving.

[0033] Adopting the electric roller 3 as the driving device can bring many benefits in the differential speed belt machine multi-layer linear layout, but the electric roller 3 is high in integration degree and difficult to dissipate heat, and the logistics industry has high working strength, so that the electric roller 3 is prone to failure, and thus the electric roller 3 of the differential speed belt machine needs to be regularly maintained and repaired, but whether the electric roller 3 fails or is regularly maintained and repaired, the electric roller 3 needs to be disassembled, and because the rack 1 of the existing differential speed belt machine of the logistics industry is compact in structure, the roller is usually longitudinally installed, which makes it necessary to dismount the transmission belt 22 from the differential speed belt machine to expose the whole machine of the rack 1 before disassembling the electric roller 3, which is very time-consuming and laborious.

[0034] To solve the problem of difficult disassembly and maintenance of the electric roller 3, another improvement of the present application is that the electric roller 3 is provided with mounting pieces 31 at both ends in the length direction thereof, and the rack 1 is connected to the mounting pieces 31 at both ends of the electric roller 3 in a side direction perpendicular to the transportation direction of the transmission belt 22. Through the above-mentioned side dismounting design, the transmission belt 22 does not need to be dismounted when the electric roller 3 is dismounted, thereby greatly reducing the time and labor required for dismounting work, and avoiding the damage risk caused by dismounting and re-mounting of the transmission belt 22.

[0035] The specific structure and connection mode of the rack 1 connecting the mounting pieces 31 at both ends of the electric roller 3 in a side direction perpendicular to the transportation direction of the transmission belt 22 are introduced below.

[0036] In this embodiment, the rack 1 includes a first rack body 11, a second rack body 12 arranged in parallel and spaced apart from the first rack body 11, the first rack body 11 is provided with a first mounting slot 13 for laterally plug-in mounting of the mounting piece 31 at one end of the electric roller 3, and the side wall of the second rack body 12 is provided with a window 14 pointing to the first support slot, the window 14 can pass through the electric roller 3 in a side direction, and the window 14 is detachably connected with a supporting plate frame 15, and the supporting plate frame 15 is provided with a second mounting slot 16 for connecting the mounting piece 31 at the other end of the electric roller 3.

[0037] By the technical scheme, the first frame body 11 and the second frame body 12 are arranged in parallel and spaced apart, which provides a stable support structure for the electric roller 3. When the electric roller 3 is disassembled, the transmission belt 22 does not need to be disassembled in advance, and only the roller group 21 for tensioning the transmission belt 22 needs to be loosened, so that the transmission belt 22 is loosened from the electric roller 3. Then, the support plate frame 15 is disassembled alone, so that the window 14 is opened to the outside. In this way, the electric roller 3 can be disassembled and pulled out of the rack 1 along the direction in which the transmission belt 22 is vertically transmitted, that is, along the lateral direction of the rack 1. Therefore, the disassembly process is greatly simplified, and the work efficiency is improved. In addition, since the support plate frame 15 is detachable, the electric roller 3 can be conveniently installed or disassembled as needed, thereby increasing the flexibility and adaptability of the rack 1.

[0038] Of course, in the embodiment, the first frame body 11 can also be provided with a window 14, and the window 14 of the first frame body 11 is detachably connected with a support plate frame 15. The first mounting groove 13 is arranged on the support plate frame 15 of the first frame body 11. In actual application, the rack 1 of the differential belt machine can be provided with the electric roller 3 on both sides for lateral disassembly, thereby further improving the flexibility of disassembling the electric roller 3,

[0039] In addition, considering that the electric roller 3 integrates a motor and a reducer, the mass of the electric roller 3 is increased compared with other rollers, especially when the application is applied to some large differential belt machines. Since the transported goods are larger, the power requirement of the configured electric roller 3 is higher, so that the electric roller 3 is abnormally heavy, and the safety risk is larger during lateral disassembly. In this regard, the embodiment is further improved: the second frame body 12 is positioned with an auxiliary support 17 on one side close to the first frame body 11, and the auxiliary support 17 is formed with an auxiliary support surface; the auxiliary support surface is used to abut and support the roller surface of the electric roller 3 when the rack 1 is installed or disassembled.

[0040] By the technical scheme, the auxiliary support 17 and the auxiliary support surface are arranged, which can provide an additional support point by the auxiliary support surface when the electric roller 3 is disassembled or installed, thereby sharing the weight of the electric roller 3 and reducing the safety risk such as abnormal falling of the electric roller 3 during operation. At the same time, the existence of the auxiliary support 17 and the auxiliary support surface makes it easier and faster for the operator to complete the disassembly and installation of the electric roller 3, thereby improving the overall work efficiency.

[0041] In order to avoid the auxiliary support surface abutting the electric roller 3 during normal operation of the differential belt machine to interfere with the electric roller 3, in the embodiment, the auxiliary support 17 is designed to be liftable and connected to the second rack 1.

[0042] The auxiliary support 17 can be connected to the second rack 1 in various ways. In this embodiment, two methods are provided. First, the second support is connected to the movable body 18 through a threaded connection. The auxiliary support 17 is connected to the movable body 18. During operation, the movable body 18 acts as a key component and is connected to the second rack 1 through one or more threaded structures. The threaded structure allows the movable body 18 to be adjusted vertically along the second rack 1. When the motorized roller 3 is removed, the movable body 18 can be connected to the second rack 12 at a higher position through a threaded connection, thereby driving the auxiliary support 17 to support the motorized roller 3. When the motorized roller 3 is in operation, the movable body 18 can be connected to the second rack 12 at a lower position through a threaded connection, thereby moving the auxiliary support 17 away from the motorized roller 3. This embodiment uses a threaded connection between the movable body 18 and the second rack 1 to achieve the vertical adjustment of the auxiliary support 17, which is simple in structure and easy to maintain and replace.

[0043] Second, a screw lifting mechanism is provided on the second support, and the auxiliary support 17 is connected to the lifting end of the screw lifting mechanism. When the auxiliary support 17 needs to be lifted, the screw lifting mechanism can be driven manually or by a motor to rotate the screw and move the nut along the screw axis, thereby pushing the lifting end and the auxiliary support 17 connected to the lifting end to move vertically. The screw lifting mechanism has a self-locking function and can directly support the auxiliary support 17. Compared with the first embodiment, the screw lifting mechanism has higher lifting efficiency and more convenient adjustment method. It can be automatically lifted by a motor, greatly reducing the burden on the operator.

[0044] Further, to improve the installation and removal efficiency of the motorized roller 3, in this embodiment, a plurality of rollers 19 are rotatably connected to the auxiliary support 17, and the auxiliary support surface is formed on the rolling surface of the rollers 19. Through the above technical solution, the auxiliary support surface is formed on the rolling surface of the rollers 19, which means that when the motorized roller 3 contacts the auxiliary support 17, it actually contacts the rolling surface of the rollers 19. In this way, rolling friction replaces sliding friction, which can greatly reduce the friction resistance and wear when the motorized roller 3 contacts the auxiliary support surface. When installing or removing the motorized roller 3, the operator can slide the motorized roller 3 along the rolling surface of the rollers 19, thereby easily moving the motorized roller 3 to the desired position, thereby improving the installation and removal efficiency.

[0045] To further protect the motorized roller 3, in this embodiment, an elastic layer is provided on the roller 19. The elastic layer is usually made of rubber, polyurethane or other materials with good elasticity and wear resistance, which can effectively absorb impact and vibration, avoid rigid collision between the motorized roller 3 and the roller 19, and protect the motorized roller 3 from damage.
