Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically to a roller with adjustable spacing. Background Technology

[0002] Conveyor belt technology is a mechanical technology used for material transportation, widely applied in various industries such as manufacturing, mining, and logistics. Idler rollers are a key component of conveyor belt systems, supporting the weight of the conveyor belt and the materials on it, ensuring smooth and continuous operation of the conveyor belt.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: the existing idlers usually adopt a fixed structure, which makes it inconvenient for users to adjust the number of idlers and the spacing of idlers according to the needs of the conveyor belt. Excessive spacing will cause excessive local stress on the conveyor belt, increase the friction between the roller and the conveyor belt, accelerate the wear of the conveyor belt and the roller, shorten their service life, and at the same time, the conveyor belt is prone to deviation, which affects the normal conveying of materials. Utility Model Content

[0004] The purpose of this utility model is to provide a roller with adjustable spacing to solve the problem of inconvenient adjustment of rollers mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a roller with adjustable spacing, including a support frame, an mounting rail mounted on the top surface of the support frame, an adjusting block mounted on the outer wall of the mounting rail, a first one-way screw mounted on one side surface of the adjusting block, a first handle mounted on one side surface of the first one-way screw, an adjusting assembly mounted on the top surface of the adjusting block, and a roller body mounted on the top surface of the adjusting assembly.

[0005] The adjustment assembly includes a housing mounted on the top surface of the adjustment block, a second one-way screw rotatably connected to the inner wall of the housing, a second handle mounted on one side surface of the second one-way screw, and a movable block mounted on the outer wall of the second one-way screw.

[0006] More preferably, the inner wall of the mounting rail is provided with a plurality of fixing holes whose internal dimensions are consistent with the external dimensions of the first one-way screw.

[0007] More preferably, the first handle and the first one-way screw constitute a helical transmission mechanism.

[0008] More preferably, the mounting rail is shaped like an I-beam.

[0009] More preferably, the adjusting block and the mounting rail form a plug-in structure.

[0010] More preferably, the connection between the adjusting block and the mounting rail is provided with a vibration damping pad.

[0011] More preferably, the second handle forms a helical transmission mechanism with the movable block via a second one-way screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, the idler body is installed on the top surface of the adjustment assembly, and the adjustment assembly forms an interlocking structure with the mounting rail through the adjustment block. The number of idler bodies can be increased or decreased as needed, and the spacing of the idler bodies can be adjusted as needed. The idler bodies are quickly fixed by the first one-way screw. At the same time, when the belt runs off-center during use, the lateral position of the idler body can be adjusted to effectively reduce the impact of belt misalignment. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a roller with spacing adjustment function, including a support frame 1, an installation rail 2 installed on the top surface of the support frame 1, an adjustment block 3 installed on the outer wall of the installation rail 2, a first one-way screw 4 installed on one side surface of the adjustment block 3, a first handle 5 installed on one side surface of the first one-way screw 4, an adjustment component 6 installed on the top surface of the adjustment block 3, and a roller body 7 installed on the top surface of the adjustment component 6.

[0021] The adjustment assembly 6 includes a housing 601 mounted on the top surface of the adjustment block 3. A second one-way screw 602 is rotatably connected to the inner wall of the housing 601. A second handle 603 is mounted on one side surface of the second one-way screw 602. A movable block 604 is mounted on the outer wall of the second one-way screw 602.

[0022] In this embodiment, as Figure 2 As shown, the inner wall of the mounting rail 2 has several fixing holes whose internal dimensions are consistent with the external dimensions of the first one-way screw 4.

[0023] In this embodiment, as Figure 3 As shown, the first handle 5 and the first one-way screw 4 constitute a helical transmission mechanism.

[0024] In this embodiment, as Figure 2 As shown, the mounting rail 2 is designed in an I-shape.

[0025] In this embodiment, as Figure 1 As shown, the adjusting block 3 and the mounting rail 2 form a plug-in structure.

[0026] In this embodiment, as Figure 1 As shown, vibration damping pads are provided at the connection between the adjusting block 3 and the mounting rail 2.

[0027] In this embodiment, as Figure 4 As shown, the second handle 603 forms a screw transmission mechanism with the movable block 604 via the second one-way screw 602.

[0028] The method of use and advantages of this utility model: The idler roller with spacing adjustment function works as follows during use:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, the idler body 7 and the adjusting component 6 are installed on the outer wall of the mounting rail 2 by inserting the adjusting block 3. Then, the number of idler bodies 7 can be increased or decreased as needed, and the spacing of the idler bodies 7 can be adjusted as required so that the fixing hole of the mounting rail 2 is consistent with the first one-way screw 4. By rotating the first handle 5, the first one-way screw 4 is rotated and inserted into the mounting rail 2, which can quickly fix the idler body 7 and the adjusting component 6. In use, when the belt runs off-center, the second handle 603 can be rotated to drive the second one-way screw 602 to rotate, so that the movable block 604 moves in the housing 601, thereby adjusting the lateral position of the idler body 7, which can effectively reduce the impact of belt running off-center.
