Abstract
Description
Technical Field
[0001] The present invention relates to the fields of belt drive and mechanical conveying, and particularly relates to a conveyor belt structure and an installation method thereof. Background Art
[0002] Belt drive is a kind of mechanical drive that uses a flexible belt tensioned on a pulley for motion or power transmission. It has the characteristics of low noise, simple structure, stable transmission, can achieve long-distance transmission, low cost, and simple maintenance, and is widely used in the field of mechanical drive. However, when the transmission speed is relatively high, ordinary flat belt drive will occur slip phenomenon, with low transmission efficiency, no accurate transmission ratio, and low transmission accuracy. Therefore, it is necessary to transform the existing flat belt to enable it to have a series of advantages that traditional flat belts do not have, such as being able to work normally at a higher conveying speed and accurately control the speed. Summary of the Invention
[0003] In view of the above problems, the present invention provides a conveyor belt structure and an installation method thereof to solve the problems raised in the above background art. The present invention drives the driving shaft to rotate through a driving motor, and the driving shaft then drives the driven shaft to rotate through the meshing of a synchronous belt inside the conveyor flat belt. The guiding strip at the middle position of the conveyor flat belt is embedded into the guiding grooves of the upper rollers of the driving and driven shafts and the supporting shaft to make the transportation process stable, thereby completing the operation of the entire conveyor belt device.
[0004] The present invention provides the following technical solution: a conveyor belt structure, comprising a driving shaft with a driving motor, a driven shaft, and a synchronous pulley set. A roller sleeved on the driving shaft rotates synchronously with the driving shaft, and a roller arranged on the driven shaft rotates synchronously with the driven shaft. A conveying flat belt is arranged on the two rollers, and a plurality of supporting rollers are arranged between the driving shaft and the driven shaft; the synchronous pulley set includes two synchronous pulleys, which are respectively arranged on the driving shaft and the driven shaft, and the synchronous pulleys in the same group correspond to each other. A synchronous belt is fixed inside the conveying flat belt, and the synchronous belt meshes with the synchronous pulley for transmission. The driving shaft drives the driven shaft to rotate through the synchronous belt of the conveying flat belt, thereby completing the operation of the entire conveying flat belt. The driving motor can be a servo motor. The roller is detachably connected to the driving and driven shafts, and rollers with different specifications and lengths can be selected according to actual production needs for combination with the synchronous pulley to suit the size requirements of the conveyor belt under different working conditions. The teeth of the synchronous pulley mesh with the teeth of the synchronous belt. A groove is opened in the middle of the width direction of the teeth of the synchronous pulley, and the grooves of the teeth of the synchronous pulley are on the same circle. A groove is opened in the middle of the width direction of the teeth of the synchronous belt, and the grooves of the teeth of the synchronous belt are on the same straight line, and the grooves of the teeth of the synchronous pulley correspond to the grooves of the teeth of the synchronous belt. The synchronous belt and the conveying flat belt are fixed by rivets or fiber lines, and the rivets or fiber lines are all arranged on the same straight line of the groove of the teeth of the synchronous belt; the fiber line is a polyester staple fiber line. When fixed by the fiber line, the conveying flat belt and the synchronous belt are fixed by a bow-shaped or square-shaped sewing method. The synchronous pulley set is two groups, and the synchronous pulleys of the two groups of synchronous pulley sets divide the rollers on the driving and driven shafts into an intermediate roller and two side rollers respectively. There are two groups of synchronous pulleys, which can ensure that the conveying flat belt is evenly stressed and runs smoothly. Corresponding guide grooves are arranged on the rollers of the driving shaft and the driven shaft, guide grooves are arranged on the supporting rollers, and guide strips matching the guide grooves are arranged on the inner side of the conveying flat belt. The height of the guide strip is less than the height of the guide groove. The guide groove is arranged on the intermediate roller. The structures of the driving shaft and the driven shaft are the same, except that the driving shaft has a driving motor.
[0005] The width of the groove of the teeth of the synchronous pulley is greater than the width of the groove of the teeth of the synchronous belt, and the width of the groove of the teeth of the synchronous belt is greater than the cross-sectional diameter of the rivets and the fiber lines. During operation, the fiber lines can be prevented from friction contact with the teeth of the synchronous belt and the pulley teeth. When the synchronous belt and the conveying flat belt are fixed by rivets, the rivets are all arranged in the grooves between adjacent teeth of the synchronous belt; the height of the teeth of the synchronous pulley is less than the depth of the groove.
[0006] Two synchronous pulleys in the same group are on the same straight line. The synchronous pulleys on the driving shaft and the driven shaft are respectively sleeved on the driving shaft and the driven shaft, and flat keys are arranged between the synchronous pulleys and the driving shaft and the driven shaft. Being on the same straight line ensures normal operation.
[0007] An installation method for the above conveyor belt structure: First, install the synchronous belt pulleys and rollers on the driving shaft and the driven shaft, then install the synchronous belt on the synchronous belt pulleys on the driving and driven shafts and perform tension adjustment. After that, cover the conveying flat belt on the rollers and the synchronous belt of the driving and driven shafts and the support shaft. At the same time, insert the guiding strips of the conveying flat belt into the guiding grooves of the driving and driven shafts and the rollers. After the conveying flat belt is tensioned and adjusted, punch through holes in the synchronous belt and the conveying flat belt together and connect the conveying flat belt and the synchronous belt with rivets or fiber threads.
[0008] When connecting the synchronous belt and the conveying flat belt, the conveying flat belt, the synchronous belt and the guiding strips are all processed with equally spaced through holes. The connection methods include connecting by a fiber thread passing up and down reciprocally; or taking two through holes as a group and connecting them by surrounding and threading with a short polyester fiber thread for each group; or connecting each through hole with a rivet.
[0009] It can be seen from the above description that in this solution, the synchronous belt is connected below the conveying flat belt, and the synchronous belt replaces the driving function of the conveying flat belt, improving the working performance of the conveyor belt: avoiding the slipping phenomenon caused by the structural characteristics of the conveying flat belt itself, and the conveying speed is stable; there is no need for too large a tension force to provide friction for driving, greatly increasing the service life of the conveying flat belt; it can easily achieve an increase in the conveying speed, breaking the limitation of the unfavorable condition that the overall size needs to be increased excessively when the conveying flat belt increases the speed; under the same conveying working condition, the overall structure is lighter in weight. The invention is firm and reliable, easy to implement, has a broad application scenario, and has high social benefits. Description of the Drawings
