Description

Technical Field

[0001] This utility model relates to the field of electric roller technology, specifically to an assembled electric roller. Background Technology

[0002] Electric rollers, as a power transmission device, are used to drive conveyor belts for transport and are widely used in various conveying systems. Based on the location of the motor, electric rollers can be divided into built-in and external types. With the development of industrial automation, the demand for electric rollers is increasing, especially in industries such as logistics, warehousing, and food processing.

[0003] In the prior art, when an electric roller drives a conveyor belt to transport items, sometimes an external electric roller with a toothed frame is needed to increase the friction, thereby driving the conveyor belt or conveyor mesh belt. The existing supports for the electric roller are mostly fixed, which is not convenient to adjust according to the size of the conveyor belt or conveyor mesh belt, resulting in poor adaptability. Some rollers with adjustable toothed frames require manual adjustment, which is inconvenient to operate and has low adjustment accuracy. Utility Model Content

[0004] The technical problem this invention aims to solve is that in existing electric rollers with gear frames, the gear frames are generally fixed and inconvenient to adjust, resulting in poor adaptability.

[0009] Furthermore, the electric roller body is provided with a toothed groove, and the first bevel gear and the second bevel gear are both rotatably disposed in the toothed groove. The outer wall of the electric roller body is provided with sliding grooves symmetrically distributed on both sides of the toothed groove. The screw is horizontally rotatably connected to the sliding groove, and the slider is horizontally slidably engaged in the sliding groove.

[0010] Furthermore, the outer wall of the electric roller body is fixed with two horizontally arranged and symmetrically distributed guide rails, and the inner wall of the movable gear frame is fixed with grooves that are symmetrically distributed and slidably engaged with the guide rails.

[0011] Furthermore, several mounting blocks arranged in a circular array are fixed to the inner walls of both ends of the electric roller body, and several bolts are arranged in a circular array on the cover plate, with the bolts threaded onto the mounting blocks.

Detailed Implementation

[0022] like Figure 1-5 As shown, an assembled electric roller includes an electric roller body 1, with cover plates 2 fixedly installed at both ends of the electric roller body 1. A drive shaft 3 is fixedly connected to the outer side of the cover plates 2. Several mounting blocks 101 arranged in a circular array are fixedly connected to the inner walls of both ends of the electric roller body 1. Several bolts 201 are arranged in a circular array on the cover plates 2. The bolts 201 are threaded to the mounting blocks 101. Support frames 4 are provided at both ends of the electric roller body 1. The drive shaft 3 is rotatably connected to the support frames 4 through bearings. The roller body also includes a fixed gear frame 5 and an adjustable gear frame mechanism 6. The fixed gear frame 5 is sleeved and fixedly connected to the middle of the electric roller body 1. The adjustable gear frame is connected to the electric roller body 1.

[0023] like Figure 3-5 As shown, the adjustable gear frame includes a motor 601 and two movable gear frames 605. The motor 601 is fixedly connected inside the electric roller body 1. The two movable gear frames 605 are sleeved on the electric roller body 1. The motor 601 drives the two movable gear frames 605 to slide towards or away from each other on the electric roller body 1. The inner wall of the electric roller body 1 is provided with a support platform 105. The motor 601 is vertically fixed to the lower end of the support platform 105. A first bevel gear 602 is fixedly connected to the output end of the motor 601. The first bevel gear 602 has symmetrically distributed second bevel gears 603 meshing on both sides and with their axes horizontally arranged. A screw 604 is fixedly connected to the outer side of the second bevel gear 603. The two screws 604 have the same pitch and are spirally connected. Conversely, each of the two movable gear frames 605 has a slider 606 fixedly connected to its inner wall. The two sliders 606 are threadedly connected to two screws 604 respectively. The electric roller body 1 has a toothed groove 102. The first bevel gear 602 and the second bevel gear 603 are rotatably disposed in the toothed groove 102. The outer wall of the electric roller body 1 has sliding grooves 103 symmetrically distributed on both sides of the toothed groove 102. The screws 604 are horizontally rotatably connected to the sliding grooves 103. The sliders 606 are horizontally slidingly engaged in the sliding grooves 103. The screws 604 are driven to rotate by the motor 601, thereby driving the two movable gear frames 605 to move towards each other or in the same direction on the electric roller body 1, so as to realize the adjustment of the distance between the two movable gear frames 605.

[0024] like Figure 4 ,5 As shown, the outer wall of the electric roller body 1 is fixed with two horizontally arranged and symmetrically distributed guide rails 104, and the inner wall of the movable gear frame 605 is fixed with grooves 607 that are symmetrically distributed and slidably engaged with the guide rails 104. The stability of the horizontal movement of the movable gear frame 605 is improved by the limiting sliding of the grooves 607 on the guide rails 104.

[0025] In use, this utility model, under the control of a PLC, uses a motor 601 to drive the first bevel gear 602 to rotate according to the specifications and dimensions of the transmission belt or conveyor network. This, in turn, drives the symmetrical second bevel gear 603 to rotate, which in turn drives the two screws 604 with the same pitch but opposite directions to rotate. This causes the two sliders 606 to slide in opposite directions within the two sliding grooves 103, which in turn causes the two moving gears 605 to slide in opposite directions on the electric roller body 1. At the same time, the grooves 607 on the inner wall of the moving gears 605 slide along the guide rail 104 to achieve limiting, thereby improving the stability of the horizontal movement of the moving gears 605. By adjusting the distance between the two moving gears 605 to match the size of the transmission belt or conveyor network, the electric roller body 1 can drive the transmission belt or conveyor network to transport items.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
