Description

Technical Field

[0001] The utility model relates to the technical field of roller lines, in particular to a roller line which is convenient for maintenance. Background Art

[0002] Roller conveyors are suitable for conveying items with flat bottoms and are primarily composed of drive rollers, frames, brackets, and drive units. They offer high conveying capacity, high speed, and smooth operation, enabling the co-linear, diverted conveying of multiple products. They are suitable for conveying various types of cargo, including boxes, bags, and pallets. Bulk materials, small items, and irregularly shaped items must be placed on pallets, and they can transport heavy individual items or withstand significant impact loads. Roller conveyors are easily connected and filtered, and multiple roller conveyors, along with other conveying equipment or specialized machines, can be combined to form complex logistics and conveying systems to meet diverse process requirements. Accumulating rollers can be used to achieve stacking and conveying of materials. Roller conveyors offer a simple structure, high reliability, and easy operation and maintenance.

[0003] However, the rollers in the roller line are generally installed independently through bearing sleeves, and the bearings of the rollers are fixed by bearing seats, thereby fixing the rollers. As a result, many parts need to be disassembled and assembled when repairing the rollers in the roller line, which is inconvenient and also reduces installation efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a roller line that is easy to maintain, which can facilitate the disassembly and assembly of rollers in the roller line, facilitate maintenance and improve installation efficiency.

[0005] In order to achieve the above purpose, a drum line with convenient maintenance is provided, comprising: two bases, mounting frames are provided on the upper ends of the two bases, bearing seats are fixedly connected to the opposite ends of the base and the mounting frames, a plurality of rollers are equidistantly provided between the two bases, and bearings are installed on the rotating shafts at both ends of the rollers, the bearings at both ends of the rollers are located in the bearing seats, C-shaped adjustment frames are fixedly connected to the two ends of the base, sliders are slidably connected in the adjustment frames, and the sliders are fixedly connected to the two ends of the mounting frames and are located at the bottom of the mounting frames, a screw rod and a guide rod are respectively installed in the middle of the adjustment frames, and A lead screw and a guide rod each extend through the middle of the slider, threadedly connected to the slider, and slidably connected to the slider. A stepper motor is fixedly connected to the upper end of the adjustment frame, and the output end of the stepper motor is fixedly connected to the lead screw. Support legs are fixedly connected to the lower end of the base, and the support legs are located at both ends of the base. Several transmission mechanisms are mounted on the side ends of the base, and the roller shafts extend into and are fixedly connected to the transmission mechanisms. The transmission mechanisms and rollers are mated and interlaced in pairs. A motor is mounted in the base, and the output end of the motor is fixedly connected to the roller shafts. This facilitates assembly and disassembly of the rollers in the roller line, facilitates maintenance, and improves installation efficiency.

[0006] According to the aforementioned maintenance-friendly roller line, the transmission mechanism includes a chain and sprockets. Two sprockets are provided and fixedly connected to the outer ends of the roller's rotating shaft. The roller's rotating shaft passes through the middle of the sprockets. The chain is provided at the outer ends of the sprockets, and one end of the chain passes through the outer ends of the two sprockets in sequence and is connected end to end. This is used to achieve synchronous rotation of the rollers in the roller line, thereby stably conveying objects on the roller line.

[0007] According to the drum line with convenient maintenance, a pressure sensor is installed on the upper end of the base and is located in the base, and is used to detect the contact pressure between the base and the mounting frame to ensure that the drum is tightly fixed.

[0008] According to the drum line convenient for maintenance, a connecting rod is fixedly connected between the supporting legs at the lower ends of the two bases, so as to improve the overall strength of the drum line when it is placed.

[0009] According to the roller line convenient for maintenance, the travel of the slider in the screw rod is greater than the height of the base, so that the bearing seat can be completely separated from the bearing on the roller surface, making it easy to disassemble and repair the roller line.

[0010] The above solution has the beneficial effect of: the motor drives the screw rod to rotate, so that the mounting frame rises and leaves the base, thereby realizing rapid disassembly and assembly of the rollers in the roller line and improving maintenance efficiency.
