Description

Technical Field

[0001] This utility model relates to the field of tracked color sorters, and in particular to a quick-release conveyor. Background Technology

[0002] Conveyors, as core equipment for material handling in modern industrial production, are widely used in various fields such as food processing, pharmaceutical manufacturing, recycled resource sorting, and mineral processing. Especially in automated sorting equipment such as tracked color sorters, conveyors play a crucial role in efficiently and accurately transporting sorted materials to designated workstations. With the increasing level of industrial automation, conveyors not only need to meet basic conveying functions but also require high reliability, ease of maintenance, and flexible adaptability to meet the demands of complex and ever-changing industrial scenarios.

[0003] However, existing conveyors have revealed numerous technical bottlenecks during long-term use. Taking belt conveyors as an example, their core transmission component—the annular enclosed belt—is prone to wear and breakage under high-speed, high-load operation. Due to the structural design limitations of traditional conveyors, belt replacement is cumbersome and time-consuming: typically, the entire machine must be moved to a spacious area, and the driven shaft assembly, drive shaft assembly, or side plates must be disassembled to create operating space. This process involves the disassembly and reassembly of numerous bolted components, requiring not only a high level of operator skill but also the potential for component misalignment, necessitating repeated adjustments to belt tension to ensure normal operation. Furthermore, traditional sprocket and chain drive systems suffer from low transmission efficiency, rapid mechanical wear, and large space requirements, further increasing maintenance costs and downtime. Existing improvement solutions largely focus on material optimization or localized structural reinforcement, such as using more wear-resistant belt materials or strengthening shaft components, but these measures fail to fundamentally simplify the maintenance process. Some equipment attempts to improve maintainability through modular design, but the lack of a systematic quick-disassembly mechanism limits their effectiveness.

[0004] Chinese patent application CN205274466U discloses a belt conveyor, in which at least one adjusting mechanism for adjusting the tension of the conveyor belt is provided on the driven roller or the driving roller. The adjusting mechanism includes elongated grooves located on both sides of the conveyor belt and along the material conveying direction for embedding at both ends of the driven shaft. An adjusting rod passes through a fixed seat and abuts against the end of the driven shaft to push the driven shaft to slide within the groove. This patent mainly relates to the adjustment of the conveyor belt tension. When the belt wears and breaks and needs to be replaced, it is still not easy to replace. Therefore, how to enable the rapid replacement and maintenance of key components such as the belt of the conveyor, reduce maintenance complexity, and improve equipment adaptability and production efficiency is a technical problem that needs to be solved. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the existing technology and provide a quick-release conveyor. By lifting the driven shaft unit, the belt is loosened, thereby achieving the purpose of quick belt replacement. In addition, other components that often need to be disassembled are also fixed to the frame body by quick-release pins and slots.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] According to one aspect of the present invention, a quick-release conveyor is provided, comprising: a frame body, a driven shaft unit, a tail panel, side panels, and a drive shaft unit;

[0008] The driven shaft unit is installed on one side of the rear end of the main frame body, and the rear end plate is installed at the front end; one end of the side end plate is connected to the rear end plate, and the other end is installed at the open end of the main frame body; the drive shaft unit is located on one side of the open end of the main frame body.

[0009] The driven shaft unit includes a driven shaft side plate, a driven shaft roller, a first adjusting screw, and a movable handle; the first adjusting screw is mounted on the driven shaft side plate via a fixed plate with holes, an adjusting plate, and a nut; the adjusting plate is mounted on a groove in the driven shaft side plate via an adjusting screw; the adjusting screw is connected to the driven shaft roller; movable handles are provided on both sides of the frame body.

[0010] Furthermore, the driven shaft unit and the driving shaft unit are mounted on the same side of the frame body.

[0011] Furthermore, both the driven shaft unit and the driving shaft unit are provided with U-shaped mounting grooves on their upper parts for connection with the frame body.

[0012] Furthermore, the tail panel and side panels are installed on both sides of the frame body by pins and slots, and are fixed by their own weight.

[0013] Furthermore, the drive shaft unit includes a drive shaft side plate, a drive shaft roller, and a second adjusting screw, wherein the second adjusting screw is connected to the drive shaft roller via a fixed plate and an adjusting plate.

[0014] Furthermore, the moving shaft side plate is provided with through holes for fixing the connecting bracket.

[0015] Furthermore, the connecting bracket is welded together from two long cylindrical structures and two short cylindrical structures. The first long cylindrical structure on the driven shaft roller side is the upper stop bracket, and the second long cylindrical structure is the lower stop bracket.

[0016] Furthermore, the front end of the movable handle is provided with a through hole for connection, and the diameter is reduced at the connection with the fixing plate.

[0017] Furthermore, after the belt is replaced, the inner edge of the belt rests on the lower crossbeam, and the two ends of the belt are respectively threaded into the driven shaft unit and the driving shaft unit.

[0018] Furthermore, the discharge hopper is fixed to the open end of the frame body by a pin and a slot.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) Enables quick belt replacement and significantly improves maintenance efficiency: By setting up quick-release driven shaft unit, movable handle and adjusting screw and other quick-release structures, the operator only needs to loosen the adjusting screw and lift the driven shaft unit to make the belt loose, without disassembling the drive shaft assembly or side plate, which greatly shortens the replacement time, avoids the tedious process of repeatedly disassembling and assembling parts and adjusting the tightness, and improves efficiency.

[0021] (2) Optimize the drive structure and reduce space occupation and mechanical loss: The electric roller directly drives the belt, replacing the traditional sprocket and chain transmission system, which reduces the volume and complexity of the transmission components, making the overall structure more compact. At the same time, it eliminates the risk of mechanical failures such as chain wear and derailment, and extends the service life of the equipment. It is especially suitable for industrial scenarios with limited space.

[0022] (3) Modular quick-release design enhances equipment adaptability and maintenance flexibility: The tail panel, side panel, discharge hopper, etc. are all quickly disassembled and assembled through pins and slots. Combined with the universal design of U-shaped mounting groove, it can adapt to the needs of different models. Each functional unit can be replaced independently. When other key components are damaged, there is no need to shut down the whole machine for maintenance, thus improving maintenance flexibility. Attached Figure Description

Detailed Implementation

[0027] 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, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model.

[0028] During the operation of a tracked color sorter, the conveyor belt is prone to damage because the speed at which the conveyor transports materials exceeds the speed at which the materials are sorted. A common solution for belt replacement is to move the conveyor to a more spacious area, remove the driven or driven shaft assembly, and, since the belt is a closed loop, remove the side plate of the conveyor if there is no space on the side for removal. After belt replacement, the removed parts are then reinstalled. After the new belt is installed, the belt tension may need to be readjusted due to changes in the installation position of the driven or driven shaft assembly. This process is time-consuming and labor-intensive, and may cause production delays due to adjustments needed during the manufacturing process.

[0029] like Figure 1 As shown, a quick-release conveyor includes: a frame body 1-1, a driven shaft unit 1-2, a tail end plate 1-3, a side end plate 1-4, and a drive shaft unit 1-5. The driven shaft unit 1-2 is installed on one side of the tail end of the frame body 1-1, and the tail end plate 1-3 is installed at its front end. One end of the side end plate 1-4 is connected to the tail end plate 1-3, and the other end is installed at the open end of the frame body 1-1. The drive shaft unit 1-5 is located on one side of the open end of the frame body 1-1. Both the driven shaft unit 1-2 and the drive shaft unit 1-5 have U-shaped mounting grooves on their upper parts for connection with the frame body 1-1.

[0030] The tail section 1-3 and side section 1-4 of the conveyor are mounted on the side of the main frame 1-1 via pins and slots, and are fixed by their own weight. The drive shaft unit 1-5 includes a drive shaft side plate, a drive shaft roller, and a second adjusting screw. The second adjusting screw is connected to the drive shaft roller via a fixing plate and an adjusting plate. The drive shaft side plate 2-1 has a through hole for fixing the connecting bracket 2-3. The connecting bracket 2-3 is welded from two long cylindrical structures and two short cylindrical structures. The first long cylindrical structure on the driven shaft roller 2-2 side is the upper stop bracket, and the second long cylindrical structure is the lower stop bracket. The front end of the movable handle 2-5 has a through hole for connection, and its diameter is reduced at the connection with the fixing plate. After the belt is replaced, the inner edge of the belt rests on the lower crossbeam 3-1, and the two ends of the belt are respectively threaded into the driven shaft unit 1-2 and the drive shaft unit 1-5. The discharge hopper 1-6 is fixed to the open end of the main frame 1-1 via pins and slots.

[0031] like Figure 2 As shown, the driven shaft unit 1-2 includes a driven shaft side plate 2-1, a driven shaft roller 2-2, a first adjusting screw 2-4, and a movable handle 2-5; the first adjusting screw 2-4 is installed on the driven shaft side plate 2-1 through a fixed plate with holes, an adjusting plate, and a nut; the adjusting plate is installed on the groove of the driven shaft side plate 2-1 through an adjusting screw; the adjusting screw is connected to the driven shaft roller 2-2; movable handles 2-5 are provided on both sides of the frame body 1-1; the driven shaft unit 1-2 and the drive shaft unit 1-5 are installed on the same side of the frame body 1-1.

[0032] like Figure 3 As shown, when the belt needs to be replaced, remove the tail panel 1-3, which is installed on the side of the frame body 1-1 via pins and slots, and the discharge hopper 1-6, which is installed at the opening end of the frame body 1-1. Then, lay down the side panel 1-4 so that it is parallel to the belt plane. Loosen the first adjusting screw 2-4 on the driven shaft unit 1-2 and the second adjusting screw on the drive shaft unit 1-5 to loosen the driven shaft and drive shaft, and pre-tighten them when the driven shaft assembly is lifted. Pull out the movable handle 2-5 to lift the driven shaft unit 1-2 through the movable handle 2-5, so that the upper stop bracket of the driven shaft roller 2-2 of the connecting bracket contacts the frame body 1-1. At this time, the belt can be pulled out from the opening side of the frame body 1-1. Place the inner edge of the new belt on the lower crossbeam 3-1 of the belt, and pass both ends through the driven shaft unit 1-2 and the drive shaft unit 1-5 in sequence. Lift the driven shaft unit 1-2 using the movable handle 2-5, rotating it until the lower stop bracket of the driven shaft roller 2-2 contacts the frame body 1-1. Adjust the belt tension to suit the current working conditions by adjusting the first adjusting screw 2-4 on the driven shaft unit 1-2 and the second adjusting screw on the drive shaft unit 1-5. Finally, pull up the side panel 1-4 to make it perpendicular to the belt plane, install the tail panel 1-3 and the discharge hopper 1-6, completing the quick belt change.

[0033] The quick-release conveyor structure in this embodiment enables rapid belt replacement through quick-release driven shaft assembly, movable handle and adjusting screw, improving equipment maintenance efficiency; and the modular design of tail panel, side panel and other components combined with pins and slots adapts to multiple models and supports independent disassembly and assembly, which also facilitates the replacement of other key components, reduces downtime, and comprehensively improves equipment applicability and production efficiency.

[0034] Furthermore, by optimizing the drive structure, the old-fashioned conveyor structure, which uses a motor to drive the drive shaft via sprockets and chains, has been replaced with an electric roller directly driving a belt. This reduces the footprint while avoiding potential mechanical damage that can occur with sprocket and chain structures. Additionally, the drive shaft side plate is not enclosed, allowing for quick replacement of the drive wheel without removing it in case of a problem.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
