Description

Technical Field

[0001] This utility model relates to the field of roller conveyor technology, and in particular to a roller conveyor with a protective structure. Background Technology

[0002] Roller conveyors are widely used in various logistics industries, effectively improving the efficiency of material handling. In practical applications, to facilitate adjustments to the conveying position, conveyors are usually interconnected.

[0003] Existing roller conveyors are mostly exposed during use and cannot limit or protect the transported items. In addition, some items have liquid or dirt on them, which causes contamination on the conveyor rollers, requiring timely cleaning by staff. Therefore, we propose a roller conveyor with a protective structure. Utility Model Content

[0004] The purpose of this invention is to provide a roller conveyor with a protective structure, which solves the existing problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, two movable rods are fixedly installed on the inner side of the fixed box, and the slider is slidably installed on the outer side of the movable rods.

[0008] Preferably, the protective plate has sliding grooves on its front and rear sides, and a telescopic plate is slidably installed on the inner side of the sliding groove. A fixing bolt is threaded on one side of the protective plate, and one end of the fixing bolt abuts against the telescopic plate.

[0009] Preferably, a support frame is fixedly installed on the top of the fixed frame, a plurality of rotating shafts are rotatably installed on the inner side of the support frame, a conveying roller is fixedly installed on the outer side of the rotating shaft, and a cleaning scraper is fixedly installed between the inner walls of the left and right sides of the support frame. The cleaning scraper is inclined and abuts against the conveying roller.

[0010] Preferably, a guide frame is fixedly installed at the bottom of the support frame, a dirt collection drawer is slidably installed on the inner side of the fixed frame, the guide frame is connected to the dirt collection drawer, a drain pipe is fixedly installed at the bottom of the dirt collection drawer, and a filter screen is provided on the inner side of the dirt collection drawer.

[0011] Preferably, two fixing plates are fixedly installed on one side of the support frame, a second motor is fixedly installed on one side of the fixing plate, a worm is fixedly installed at the output end of the second motor, and a worm wheel is fixedly installed on the outer side of the rotating shaft, with the worm and the worm wheel meshing with each other.

[0012] Preferably, the outer side of the conveying roller is provided with anti-slip protrusions, and the conveying roller is made of rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) The present invention provides a roller conveyor with a protective structure. The workpiece to be transported is placed above the conveying roller, and the second motor is controlled to drive the worm to rotate. After the worm rotates, it can drive multiple worm wheels and rotating shafts that mesh with it to rotate. After the rotating shafts rotate, they can drive the conveying roller to rotate, so that the conveying roller can transport the workpiece. The first motor can be started according to the height of the workpiece, and the lead screw can be driven to rotate. The lead screw can drive the slider, electric telescopic rod and protective plate to rise and fall through the threaded connection, and the electric telescopic rod can be controlled to drive the protective plate to move, so that the workpiece is located in the middle of the conveying roller, which can prevent the workpiece from deviating and falling during the transport process.

[0015] (2) The present invention provides a roller conveyor with a protective structure. According to the length of the support frame, the telescopic plate can slide out from the inside of the protective plate and the position of the protective plate can be locked by fixing bolts. This device can protect conveying structures of different lengths. When there is dirt and liquid on the outer surface of the conveying roller, the cleaning scraper can scrape it off. The cleaning scraper is inclined so that the scraped dirt can fall off through the guide frame. The inside of the dirt collection drawer is equipped with a filter screen so that the liquid can be discharged from the drain pipe. Solid debris can be cleaned by simply taking out the dirt collection drawer. This makes the device easier and less time-consuming to clean later. Attached Figure Description
