Technical Field
The invention relates to the field of conveying belts, in particular to a conveying belt module with low noise and low vibration.
Background
At present, compared with a belt conveyor belt, the modular conveyor belt is not prone to snaking and deflection, has the characteristics of cutting resistance, collision resistance, oil resistance, water resistance and the like, can be widely applied to the fields of assembly lines, automatic production, logistics transmission and the like, and is necessary equipment for conveying articles in various fields.
The existing modular conveying belt is formed by combining a plurality of modular units, a plurality of balls are arranged in a sheet of each module, the conveying belt is driven by gears to move, meanwhile, the balls can rotate after being driven, and the moving direction of goods driven by the rotation of the balls is perpendicular to the conveying direction of the conveying belt, so that the goods can be sorted. For example, goods are conveyed on the conveying belt in the front-back direction at the beginning, and when the goods reach a sorting point, the corresponding balls rotate to drive the goods to move in the left-right direction and exit from the main conveying belt, so that sorting is realized.
The existing conveyor belt module can refer to the chinese invention with the application number of cn201910926125.x, and the way of mounting the balls in the sheet is as follows: the sheet is internally provided with a ball frame, the ball frame is internally provided with two pin holes, the balls are placed in the ball frame, a rotating shaft penetrates through the pin holes and the balls, and finally, two ends of the rotating shaft are fixed in the ball frame. The ball cup joints outside the pivot, can rotate around the pivot, and the pivot is fixed simultaneously.
Because the balls rotate around the rotating shaft, a certain gap must exist between the balls and the rotating shaft (if the balls and the rotating shaft are in tight fit or interference fit, the balls cannot rotate around the rotating shaft). However, in the practical use process, the applicant finds that the balls are pressed by the weight of the goods, and a gap exists between the balls and the rotating shaft, so that the balls continuously collide with the rotating shaft in the rotating process, and particularly in the case of heavy goods, the conveying belt generates very large vibration and noise; and the abrasion generated between the ball and the rotating shaft is also large, so that the service life of the conveyor belt module is short, and the replacement period is short.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide a conveyor belt module with low noise and low vibration, wherein a bearing is arranged on a rotating shaft, and a ball is sleeved on the bearing, so that the ball is tightly matched with the bearing, and meanwhile, the rotating shaft is tightly matched with the bearing; when the ball can realize good rotation, because no longer have the clearance between with the pivot, can effectively reduce the vibration and the noise of conveyer belt.
The invention is realized by the following technical scheme:
a low noise, low vibration conveyor belt module comprising: sheet, rotating shaft, ball and bearing; the sheet is provided with a ball frame, and two ends of the rotating shaft are fixedly connected to the inner walls of two ends of the ball frame; the rotating shaft is provided with a bearing, the inner ring of the bearing is tightly sleeved on the rotating shaft, and the ball is tightly sleeved on the outer ring of the bearing.

Further, the two lugs have the same thickness.
Further, a pin hole on a lug in the ball frame extends towards the inside of the sheet, and the depth of the pin hole is smaller than the distance between the lug and the outer edge of the sheet; a pin hole on the other lug extends towards the inside of the sheet and penetrates through the sheet, and the depth of the pin hole is equal to the distance from the lug to the outer edge of the sheet.
Furthermore, a plurality of connecting blocks extend outwards from two sides of the sheet material, and the connecting blocks on the two sides are arranged in a staggered mode; the pin hole penetrating through the sheet is positioned on a midline between two adjacent connecting blocks on one side of the pin hole, and the other pin hole is positioned on a central extension line of the connecting block on one side of the pin hole.
Furthermore, each connecting block is provided with a shaft penetrating hole, and the shaft penetrating holes of the connecting blocks on the same side are consistent in size and are located on the same axis.
Further, the thickness of the lug is less than the thickness from the ball frame to the outer edge of the sheet.
