Description

Technical Field

[0001] This utility model relates to material conveying, and more particularly to a long-distance conveying mechanism for rolled profiles. Background Technology

[0002] Traditional chain conveyors typically employ a fully powered chain drive structure, where all rollers are connected by chains and driven by motors. This design has significant drawbacks when extending conveying lengths: Firstly, fully powered rollers require numerous sprockets, chains, and other transmission components, leading to high equipment costs and complex structures. Furthermore, long-distance transmission is prone to uneven chain tension and accelerated wear, affecting conveying stability. Secondly, the fully powered layout occupies a large space, making it difficult to increase conveying distance by extending rollers in a straight line in workshops with limited space. The additional power consumption also increases energy costs.

[0003] Furthermore, traditional all-powered roller conveyor designs lack adaptability for scenarios requiring flexible layout adjustments (such as turns and branches) or temporary increases in conveyor length. For example, in a cross-belt sorting system at a logistics sorting center, if the sorting line length needs to be temporarily extended, the modification of all-powered rollers involves a complete redesign of the transmission system, which is time-consuming, labor-intensive, and costly. Simultaneously, for goods with fragile surfaces or uneven weight distribution, the rigid transmission of all-powered rollers may cause damage due to localized pressure concentration, or affect conveying efficiency due to fluctuations in transmission resistance. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing technologies by providing a long-distance conveying mechanism for rolled profiles.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a long-distance conveying mechanism for rolled profiles, comprising a base, a drive motor, a chain drive system driven by the drive motor, and multiple rollers; the multiple rollers are arranged laterally on the base at intervals and rotatably, and the multiple rollers include powered rollers and free rollers; wherein, the end of the powered roller is provided with a sprocket assembly, the sprocket assembly is meshed with the chain drive system, so that the powered roller is directly driven by the chain drive system and becomes an active roller; the end of the free roller is provided with a rolling bearing for connecting to the base, and the rotational power of the free roller comes from the friction between the goods being conveyed above it and the surface of the roller, and the goods are driven by adjacent powered rollers; specifically, the goods may be driven by powered rollers that are transported on the same level as the free rollers.

[0006] Furthermore, the sprocket assembly includes an inner sprocket and an outer sprocket mounted at the front end of the power roller; the inner sprocket is used to engage with the chain that drives the power roller, and the outer sprocket is used to transmit power to the next stage power roller through the chain.

[0007] Furthermore, the powered rollers and the free rollers are arranged along the conveying direction according to a preset rule, which is that the arrangement spacing is set based on the minimum size of the goods to be conveyed, so as to ensure that any size of goods remains in contact with at least one of the powered rollers during the conveying process.

[0008] Furthermore, it also includes two baffles, which are fixedly installed on both sides of the base along the length direction and located outside the ends of the power roller and the free roller, to form a channel for transporting goods and to laterally limit the goods.

[0009] Furthermore, the rolling bearing connected to the free roller is a low-resistance bearing.

[0010] Furthermore, the low-resistance bearing is any one of a deep groove ball bearing, a self-aligning ball bearing, or a needle roller bearing.

[0011] Furthermore, the chain drive system includes a chain, and the drive motor drives the first power roller through the chain, and subsequent power rollers are driven in series through the chain drive.

[0012] Furthermore, the drive motor is a variable frequency motor, a servo motor, or a worm gear reducer motor.

[0013] Furthermore, free rollers are distributed between the two powered rollers.

[0014] Compared with the prior art, this utility model has the following advantages.

[0015] This invention, which installs free rollers, solves the problem of traditional powered roller conveyor lines relying on chain drive mechanisms for a single transmission route. Free rollers rely on the power of powered rollers to transmit goods, eliminating the need for chain drive. In scenarios requiring turns, branches, or changes in conveying height, adding such rollers effectively enhances the system's flexibility and adaptability. Attached Figure Description

[0024] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0025] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The singular forms “a,” “the,” and “the” as used in the embodiments of this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0026] Depending on the context, words such as “if” or “suppose” used here can be interpreted as “when”, “in response to determination”, or “in response to detection”.

[0027] For ease of understanding, the embodiments of this disclosure will be described in detail first.

[0028] Example 1, such as Figure 1-6 As shown, the long-distance conveying mechanism for rolled profiles includes a base 1, on which power rollers 2 are horizontally distributed. Free rollers 3 are distributed between the power rollers. The front and rear ends of the power rollers 2 and the free rollers 3 are respectively connected to fixed rolling bearings 5 ​​on both sides of the base 1. An inner sprocket 6 and an outer sprocket 7 are respectively installed at the front end of the power rollers 2. The inner sprocket 6 is engaged with a chain 8 and receives power transmitted by a drive motor 9, driving the power rollers 2 to rotate relative to each other on the rolling bearings 5. In one embodiment, long distance refers to a conveying length of 30m or more.

[0029] The outer sprocket 7 transmits power to the next stage of chain drive via the chain 8. The free roller 3 transmits power to the rotating goods via the power roller 2. The baffle 4 is fixed on the base 1 and is distributed laterally at both ends of the power roller 2.

[0030] When the conveyor transports goods, the goods are on the roller axis. When they come into contact with the power roller 2, they are driven by the engagement of the inner sprocket 6 and the outer sprocket 7 with the chain 8. When they come into contact with the free roller 3, they are driven by the power transmitted from the power roller 2 to the goods. This design optimizes the arrangement of the rollers on the roller axis. In cases of long conveying distances and large goods, the power roller 2 is arranged according to the minimum size of the goods to be conveyed, which effectively reduces the power loss of the drive motor 9. At the same time, it reduces the installation of the inner sprocket 6, the outer sprocket 7 and the chain 8, which not only improves the conveying efficiency, but also reduces the production cost of the power roller conveyor line and the subsequent maintenance work.

[0031] Example 2: Goods are placed at one end of the conveying mechanism. The drive motor 9 transmits power to the inner sprocket 6 via the chain 8 while maintaining constant output power, causing the power roller 2 to rotate in a specific direction. The power roller 2 transmits power to the goods it contacts, causing the goods to move in a specific direction. After the goods come into contact with the free roller 3, the power received by the power roller 2 is transmitted to the contacting free roller 3, causing the free roller 3 to move in a specific direction without chain drive. The goods are conveyed to the designated position through the directional movement of the power roller 2 and the free roller 3. The drive motor 9 drives the first-stage chain drive, and the power is transmitted from the first stage to the power roller 2 in the roller axis. The rotation of the free roller 3 does not rely on chain drive. The drive motor 9 reduces power loss during the drive, and the conveying line is greatly extended compared to the traditional power roller axis conveyor line, greatly improving the overall conveying efficiency of the roller axis. At the same time, the chain drive affects the stability of the goods transported by the power roller 2. The power roller conveyor line reduces the chain drive mechanism and effectively improves the stability of the conveying mechanism in transporting goods.

[0032] Example 3: By optimizing the arrangement of rollers on the roller axis, a free roller 3 that rolls on a low-resistance bearing is set between the power rollers 2. The drive of the free roller 3 does not rely on the meshing connection between the chain 8 and the inner sprocket 6 and the outer sprocket 7. The front end of the free roller 3 is directly connected to the rolling bearing 5. Compared with the traditional roller transport line where each roller is driven by the meshing connection between the inner sprocket 6 and the chain 8, the free roller 3 does not rely on the meshing connection between the chain 8 and the inner sprocket 6 and the outer sprocket 7 during the operation of the conveyor mechanism. This effectively reduces the chain drive structure, simplifies the roller axis structure, and greatly reduces production costs and subsequent maintenance work.
