The various technical effects of the preferred technical solutions provided by this utility model are detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides a quick-release idler roller assembly, including a crossbeam, a side rotating support column, a support base, and side idlers. The crossbeam is provided with a side fixing frame and a middle fixing frame. A side rotating support column is provided between the first end of the support base and the side fixing frame. The second end of the support base is connected to the middle fixing frame through a middle rotating shaft, so that the side idlers are inclined. The side idlers are rotatably mounted on the support base. A first fixing bolt and a side rotating shaft are installed between the side rotating support column and the side fixing frame. The first fixing bolt is located above the side rotating shaft, and a second fixing bolt fixes the support base and the side rotating support column.

[0005] Preferably, the cross-section of the side rotating support is configured as a U-shaped structure, the cross-section of the side fixing frame is configured as a U-shaped structure, and the side fixing frame is disposed within the U-shaped cavity of the side rotating support.

[0013] The technical solution provided in this application document has the following beneficial effects: This utility model provides a quick-release idler roller assembly, including a crossbeam, a side rotating support column, a support base, and an edge idler roller. The crossbeam provides support and is equipped with an edge fixing frame and a middle fixing frame. The edge idler roller is rotatably mounted on the support base. A side rotating support column is provided between the first end of the support base and the edge fixing frame. The second end of the support base is connected to the middle fixing frame via a middle rotating shaft, so that the edge idler roller is inclined. At the position where the side rotating support column is connected to the edge fixing frame, a first fixing bolt and an edge rotating shaft are installed between the side rotating support column and the edge fixing frame.

A second fixing bolt is installed between the support base and the side rotating support column. When replacing the side roller, the first fixing bolt located at the bottom is removed, and at the same time, the second fixing bolt is also removed. Under the pressure of the side roller and the support seat, the side rotating support tilts outward, making it easier to replace the side roller. Thus, along the height direction of the side fixing frame, the first fixing bolt and the side rotating shaft are simultaneously fixed to the side fixing frame and the side rotating support. This limits the position of the side rotating support. At the same time, removing the first fixing bolt at the bottom allows the side rotating support to rotate around the side rotating shaft, causing the support seat to tilt, facilitating the replacement of the side roller. This forms a two-point positioning and single-point movement form, allowing the mechanism to move and reducing cumbersome operation, safety risks, and limited working space. Even a single person can easily operate it without the need for multiple people to cooperate, improving efficiency and indirectly reducing production losses caused by downtime, thus optimizing manpower and cost input.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] This specific embodiment provides a quick-release idler assembly to solve the technical problem of inconvenient replacement of idlers in the prior art.

[0019] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.

[0020] Reference Figures 1-4This utility model provides a quick-release idler roller assembly, including a crossbeam 1, a side rotating support column 2, a support base 3, and an edge idler roller 4. The crossbeam 1 provides support and is provided with an edge fixing frame 11 and an intermediate fixing frame 12. The edge idler roller 4 is rotatably mounted on the support base 3. The side rotating support column 2 is provided between the first end of the support base 3 and the edge fixing frame 11. The second end of the support base 3 is connected to the intermediate fixing frame 12 through an intermediate rotating shaft 121, so that the edge idler roller 4 is inclined. At the position where the side rotating support column 2 is connected to the edge fixing frame 11, a first fixing bolt 8 and an edge rotating shaft 111 are installed between the side rotating support column 2 and the edge fixing frame 11. The first fixing bolt 8 and the edge rotating shaft 111 are distributed along the height direction of the edge fixing frame 11, and the height of the edge rotating shaft 111 is higher than the height of the first fixing bolt 8. A second fixing bolt 9 is installed between the support base 3 and the side rotating support column 2. When replacing the side roller 4, the first fixing bolt 8 located at the bottom is removed, and at the same time, the second fixing bolt 9 is removed. Under the pressure of the side roller 4 and the support seat 3, the side rotating support 2 tilts outward, making it easier for people to replace the side roller 4. Thus, along the height direction of the side fixing frame 11, the first fixing bolt 8 and the side rotating shaft 111 are simultaneously fixed to the side fixing frame 11 and the side rotating support 2, which can limit the position of the side rotating support 2. At the same time, by removing the first fixing bolt 8 at the bottom, the side rotating support 2 can rotate around the side rotating shaft 111 as the axis of rotation, causing the support seat 3 to tilt, making it easier to replace the side roller 4. This forms a two-point positioning and single-point movement form, which allows the mechanism to move, reduces the complexity of operation and safety risks, and reduces the limitation of working space. Even a single person can operate it easily without the need for multiple people to cooperate, which improves efficiency and indirectly reduces production losses caused by downtime, optimizing manpower and cost input.

[0021] Further optimization of the scheme: the cross-section of the side rotating support 2 is set as a U-shaped structure, the side fixing frame is set as a U-shaped structure, and the side fixing frame 11 is set in the U-shaped cavity of the side rotating support 2. Specifically, the side fixing frame 11 and the U-shaped structure of the side rotating support 2 are set opposite to each other to form an integral cavity. The side rotating shaft 111 and the first fixing bolt 8 are simultaneously inserted into the side wall of the side fixing frame 11 and the side rotating support 2, which can ensure the firmness of the connection position.

[0022] To further optimize the design, a rotating beam fixing seat 5 is provided on the top of the side rotating column 2 to facilitate the support of the support seat 3. The rotating beam fixing seat 5 is connected to the support seat 3. Since the support seat 3 is inclined, the rotating beam fixing seat 5 is inclined to facilitate the contact area between the rotating beam fixing seat 5 and the support seat 3.

[0023] To further optimize the design, the rotating beam fixing seat 5 is set to an inverted V shape, which increases the stability of the rotating beam fixing seat.

[0024] Further optimization of the scheme: the support base 3 includes a rotating beam 31, a side roller shaft support 32, and a central rotating support column 33. The cross-section of the rotating beam 31 is set as V-shaped. Since the rotating beam fixing seat 5 is inclined, this increases the contact area between the rotating beam fixing seat 5 and the rotating beam 31, making it easier to fix the rotating beam fixing seat 5 and the rotating beam 31. The side roller shaft support 32 is installed on both sides of the rotating beam 31, and the side roller 4 is installed on the side roller shaft support 32. The central rotating support column 33 is welded to the lower part of the second end of the rotating beam 31, and the first end of the rotating beam is connected to the side rotating support column 2, thereby realizing the fixation of the support base 3.

[0025] Further optimization of the scheme: during material conveying, the conveyor belt is laid on the side idler rollers 4 to form a U-shaped or V-shaped conveying mechanism to facilitate material conveying. In order to facilitate the formation of such a structure, the side fixing frame 11 and the middle fixing frame 12 are set as a group, and two groups are symmetrically arranged. The side fixing frame 11 is set at both ends of the crossbeam 1 to form a V-shape.

[0026] To further optimize the design and facilitate the formation of a U-shaped structure, an intermediate roller shaft support 6 is also provided on the crossbeam 1. The intermediate roller shaft support 6 is installed in the middle position between the two intermediate fixing frames 12, and the intermediate roller 7 is installed on the intermediate roller shaft support 6. That is, a set of side fixing frames 11 and intermediate fixing frames 12 are respectively provided at both ends of the intermediate roller shaft support 6, thus forming a U-shaped structure.

[0027] To further optimize the design, in order to facilitate the rotation of the support base 3 and the side rotating column 2, the end faces of the side fixing frame 11 and the middle fixing frame 12 are set as arc surfaces.

[0028] To further optimize the design, in order to ensure that the side fixing frame 11 and the middle fixing frame 12 can be stably installed, the side fixing frame 11 and the middle fixing frame 12 are welded to the crossbeam 1.
