the sheet is provided with a ball frame, and the inner walls of two ends of the ball frame are provided with lugs;
the ball is provided with a rotating shaft, and the ball is connected to the lugs at the two ends of the ball frame through the rotating shaft.
Further, the thickness of the lug is smaller than the thickness from the ball frame to the outer edge of the sheet.
Furthermore, the orthographic projection of the two lugs in the same ball frame in the horizontal direction is coincident with the orthographic projection of the rotating shaft in the horizontal direction.
Further, the distance between the two lugs in the same ball frame is larger than the length of the ball.
Furthermore, the orthographic projection of the two lugs in the same ball frame in the horizontal direction is coincident with the midpoint of the orthographic projection of the ball frame in the horizontal direction.
Furthermore, two lugs in the same ball frame are provided with pin holes, and the rotating shaft is inserted into the pin holes to fix the balls in the ball frame.
Furthermore, a pin hole on one 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 interior of the sheet material and penetrates through the sheet material, and the depth of the pin hole is equal to the distance between the lug and the outer edge of the sheet material.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
A conveyor belt module belongs to a partial module in a modular conveyor belt, as shown in figure 1, a plurality of modules are spliced with each other to form a complete conveyor belt; the lower surface of the conveying belt is provided with clamping grooves which are longitudinally distributed, the clamping grooves are matched with teeth of the gears on the conveying belt, and the teeth of the gears drive the conveying belt to advance when the gears rotate. Wherein a single conveyor module comprises a sheet 1 and balls 4 retained on the sheet 1.
The width of the sheet 1 can be set according to the actual situation, as shown in fig. 2 to 4, the sheet 1 is provided with ball frames 2, and the number of the ball frames 2 can be planned according to the actual width of the sheet 1; the inner walls of the two ends of the ball frame 2 are provided with lugs 3; and ball 4 then the suit is outside the pivot, and ball 4 uses the pivot to rotate as the axle, and ball 4 connects on the lugs 3 at ball frame 2 both ends through the both ends of its pivot to realize ball 4 spacing in ball frame 2, when the conveyer belt forward motion, ball 4 also can rotate as the axle by the pivot.
The distance between the two lugs 3 in the same ball frame 2 is greater than the length of the balls 4, so that the arrangement of the lugs 3 does not influence the normal rotation of the balls 4, even if the balls 4 rotate at high speed when the conveying belt advances at high speed, the balls 4 firstly impact the lugs 3 instead of directly impacting the side wall of the sheet 1, the sheet 1 can be prevented from cracking, and the service life of the sheet 1 is prolonged.
And the thickness of lug 3 is less than 2 to the thickness between the sheet 1 border of ball frame, and lug 3 is too thick can make the material used too much, increases manufacturing cost, and the whole weight of lug 3 increases simultaneously, increases the degree of difficulty of being connected between lug 3 and the sheet 1 inner wall, leads to lug 3's fastness poor, drops easily after the striking.
Because the pivot of ball 4 is connected on lug 3, in order to avoid ball 4 skew to appear in ball frame 2 installation, it is same two lugs 3 in ball frame 2 orthographic projection on the horizontal direction and ball frame 2 orthographic projection's mid point coincide mutually for the pivot is connected on lug 3 back ball 4 axle center is in ball frame 2 internal midline, two lugs 3 orthographic projection on the vertical face coincide mutually promptly, and the distance on lug 3 and ball frame 2 both sides is all the same, avoids ball 4 excessively to be close to ball frame 2 lateral wall, increases unnecessary frictional force to ball 4's rotation.
The rotating shaft is connected with the lugs 3 of the ball frame 2 through the pin holes 5, the two lugs 3 in the same ball frame 2 are provided with the pin holes 5, and the rotating shaft is inserted into the pin holes 5 to fix the balls 4 in the ball frame 2. In order to further improve the assembling convenience of the ball 4, a pin hole 5 on one lug 3 in the ball frame 2 extends towards the inside of the sheet material 1, and the depth of the pin hole 5 is smaller than the distance between the lug 3 and the outer edge of the sheet material 1, namely, the pin hole 5 does not penetrate through the sheet material 1; the pin hole 5 on the other lug 3 extends to the inside of the sheet 1 and penetrates through the sheet 1, the depth of the pin hole 5 is equal to the distance between the lug 3 and the outer edge of the sheet 1, namely, the pin hole 5 just penetrates through the sheet 1, so that when the ball 4 is assembled, the ball 4 can be firstly placed in the ball frame 2, then a rotating shaft is inserted into the pin hole 5 penetrating through the sheet 1 from the outside of the sheet 1, then the rotating shaft passes through the axle center of the ball 4 and is finally clamped into the pin hole 5 not penetrating through the sheet 1, thereby completing the assembling action of the ball 4 and improving the assembling speed of the ball 4.
In order to prevent the rotating shaft from being inserted into the pin hole 5 and blocked by the connecting blocks 6 on the sheet material 1, the pin hole 5 penetrating through the sheet material 1 is arranged on a midline between two adjacent connecting blocks 6 at one side of the pin hole 5, and the other pin hole 5 is coincided with an extension line of one connecting block 6 at one side of the pin hole 5; in addition, the orthographic projection of the two lugs 3 in the ball frame 2 in the horizontal direction is coincided with the orthographic projection of the rotating shaft in the horizontal direction, and the pin hole 5 is formed in the middle point of the lug 3, so that the rotating shaft, the pin hole 5 and the lugs 3 can be kept in the same straight line, the rotating shaft can be conveniently and accurately positioned on the pin hole 5 in the ball frame 2, the pin hole 5 is rapidly inserted into the pin hole 5, and the assembly efficiency of the ball 4 is improved.
In addition, as the pin hole 5 is arranged on the midpoint of the protruding block 3, the pin hole 5 is prevented from excessively inclining to one side of the protruding block 3, and when a hole is punched, the side of the protruding block 3 is easily too thin to cause a crack, the height of the protruding block 3 is set to be larger than the diameter of the rotating shaft and smaller than the height of the ball frame 2, and the upper edge of the protruding block 3 is at the same height with the upper surface of the sheet 1, as shown in fig. 3 and 4, the rotating shaft is positioned at a position where the inner side wall of the sheet 1 is relatively upper, the distance from the upper vertex of the ball 4 to the upper surface of the sheet 1 is larger than the distance from the lower vertex of the ball 4 to the lower surface of the sheet 1, namely, the sheet 1 is obviously protruded above the ball 4, the contact area between the ball 4 and the goods on the sheet 1 is increased, the goods are prevented from directly.
