Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a split-type return roller frame. Background Technology

[0002] Currently, roller conveyor lines are often used in logistics transfer, production line connection and warehousing systems to transport goods; roller conveyor lines are composed of core components such as idlers, idler frames and conveyor belts;

[0003] Since idlers are consumable parts, they usually need to be replaced after a period of use. However, traditional idler frames are integral beam support structures, which cause the upper surface of the idler to be in close contact with the conveyor belt, and the idler is crushed by the conveyor belt from below. Under these conditions, replacing the idler requires the use of large tools or equipment to pry up the conveyor belt to create the space needed to replace the idler. The aforementioned operation is not only dangerous, but also difficult and inefficient.

[0004] To solve the aforementioned technical problems, it is urgent to propose a split-type return roller frame. Summary of the Invention

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides a split return idler frame, which solves the technical problem of "how to efficiently replace idlers while reducing the risk of operation" in the existing idler frames of roller conveyor lines.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0011] The central fixing frame includes a first split bracket disposed at the second end of the first sleeve and a second split bracket disposed at the third end of the second sleeve.

[0012] The roller assembly includes a first roller component and a second roller component. One end of the first roller component is connected to the top of one of the end fixing brackets, and the other end of the first roller component is connected to the first split bracket. One end of the second roller is connected to the top of another end fixing bracket, and the other end of the second roller is connected to the second split bracket.

[0013] Optionally, the length ratio of the first sleeve to the second sleeve is 2:1.

[0014] Optionally, the first roller assembly includes a first inclined roller and a horizontal roller, and the second roller assembly includes a second inclined roller;

[0015] The first inclined roller is mounted on the first sleeve via a fixed end bracket and a connecting bracket on one side. The horizontal roller is mounted on the first sleeve via the other side of the connecting bracket and a first split bracket. The second inclined roller is mounted on the second sleeve via a second split bracket and a fixed end bracket on the other side.

[0016] Optionally, the connecting bracket includes an integrally formed first connecting piece and a second connecting piece;

[0017] The first connecting piece is in an inclined state and is connected to one end of the first inclined roller, while the second connecting piece is connected to one end of the horizontal roller.

[0018] Optionally, it may also include a limiting component, which includes a first limiting member, a second limiting member, and a third limiting member;

[0019] The first limiting member and the second limiting member are located at both ends of the slide, and the third limiting member is located at two-thirds of the position of the slide.

[0020] Optionally, the fixed crossbeam assembly includes two fixed crossbeams, which are detachably connected to the first sleeve and the second sleeve, respectively.

[0021] The beneficial effects of this application are as follows:

[0022] In this application, by respectively fitting the first sleeve and the second sleeve onto the outer ends of the slide, the following conditions are met: the first sleeve and the second sleeve can slide along the length direction of the slide to form a separable pull-out frame body; the first inclined roller and the horizontal roller are fixed above the first sleeve based on a fixed connector, and the second inclined roller is fixed above the second sleeve based on a fixed connector; two fixed crossbeams are detachably connected to the first sleeve and the second sleeve respectively.

[0023] Based on the aforementioned structure, after releasing the threaded lock between the fixed crossbeam located on one side of the first sleeve and the preset position, the first inclined roller and the horizontal roller can be extended outward until they are separated from the conveyor belt, thereby reducing damage to the conveyor belt and improving the roller replacement efficiency; after releasing the threaded lock between the fixed crossbeam located on one side of the second sleeve and the preset position, the second inclined roller can be extended outward until it is separated from the conveyor belt, thereby reducing damage to the conveyor belt and improving the roller replacement efficiency.
