Technical Field

The invention relates to the field of conveyor belts, in particular to a modular plastic conveyor belt.

Background

At present, because the modular transmission band is formed by the concatenation of different composite module, and when the transmission band was installed on transmission equipment's fuselage, the strake at transmission equipment fuselage both ends can restrict the operation direction of transmission band, avoids the transmission band phenomenon of off tracking to appear at the operation in-process, consequently brings for belt conveyor say, the modular transmission band is assembled simply, and the phenomenon of off tracking appears is less, consequently by wide application in various fields.

However, in order to avoid the situation that the edges at the two ends of the conveying belt can rub against the edge strips of the machine body when the conveying belt runs at a high speed, and the sheet of the conveying belt is easy to break, the thicknesses of the edges at the two ends of the conveying belt are properly increased in the prior art, and the sheet is prevented from breaking after being worn.

However, since the sheet is generally made of plastic formed by injection molding, the increase of the thickness at the edge of the sheet can result in the lengthening of the injection molding cooling time of the sheet, and the foaming and expansion of the surface of the sheet can be caused by the external cold and internal heat of the sheet in the injection molding cooling process, which affects the production quality of the sheet.

The purpose of the invention is realized by adopting the following technical scheme:

a modular plastic conveyor belt, comprising:

the sheet material is formed into a plastic sheet material through injection molding, balls are assembled on the sheet material, and ball barriers are arranged between the adjacent balls;

Further, the heat dissipation holes penetrate through the sheet.

Further, the heat dissipation hole extends along the longitudinal direction of the edge portion.

Further, the number of the heat dissipation holes is set to three, and the three heat dissipation holes are longitudinally arranged at the edge part.

Furthermore, the central line of the heat dissipation hole coincides with the central line of the edge part, so that the distance from the edge line of the heat dissipation hole at one side of the central line to the edge line of the edge part at the side is equal to the distance from the edge line of the heat dissipation hole at the other side of the central line to the edge line of the edge part at the side.

Further, the distances between the adjacent heat dissipation holes are the same.

Further, on the central line of the heat dissipation holes, the distance from the midpoint between the adjacent heat dissipation holes to the edge of the heat dissipation holes is equal to the distance from the midpoint to the edge of the edge.

Further, the heat dissipation holes are in a long round hole structure.

Compared with the prior art, the invention has the beneficial effects that:

the thickness of the outer edge of the sheet at the outermost end of the combined module is larger than the thickness of the ball partition, and at least one heat dissipation hole is formed in the outer edge of the sheet at the outermost end of the combined module, so that the outer edge with thick thickness can dissipate heat in time, the cooling area of the sheet edge during injection molding is increased, the cooling speed of the sheet edge is accelerated, and the cost rate of sheet production is increased.

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 modular plastic conveyor belt comprises a plurality of sheets 2 spliced to one another.

As shown in fig. 1 and 2, the sheet 2 is a plastic sheet 2 formed by injection molding, the sheet 2 is assembled with the balls 3 after the injection molding of the sheet 2, the ball barriers 4 are arranged between the adjacent balls 3 on the sheet 2, and the ball barriers 4 can be used for isolating the adjacent balls 3 to prevent the adjacent balls 3 from colliding with each other during high-speed rotation and affecting the stability of the conveying belt.

The method comprises the following steps that a plurality of sheets 2 are transversely assembled to form a combination module 1, connecting blocks 5 which are distributed in a staggered mode are arranged at two ends of each sheet 2, pin holes are formed in the connecting blocks 5, when adjacent combination modules 1 are longitudinally arranged, the connecting blocks 5 of the previous combination module 1 are correspondingly inserted into gaps between the adjacent connecting blocks 5 in the next combination module 1, and then a penetrating shaft penetrates into the pin holes, so that the previous combination module 1 and the next combination module 1 are spliced with each other; when a plurality of the combined modules 1 are longitudinally assembled, a complete transmission belt can be formed.

The outer edge of the sheet 2 positioned at the outermost end of the combined module 1 is set as an edge part 6 of the combined module 1, and the thickness of the edge part 6 is larger than that of the ball partition 4, so that the wear resistance at the edge of the conveying belt is increased, and the sheet 2 is prevented from being broken; at least one heat dissipation hole 7 is arranged on the edge part 6, and the heat dissipation hole 7 can accelerate the heat dissipation speed of the edge part 6; but also can save the injection molding cost of the sheet 2 and reduce the weight of the sheet 2.

The heat dissipation holes 7 penetrate through the sheet 2, namely, the hole depth of the heat dissipation holes 7 is equal to the thickness of the sheet 2, so that the heat dissipation of the edge 6 of the sheet 2 is uniform; the heat dissipation holes 7 extend along the long side direction of the edge portion 6, and the heat dissipation holes 7 are in an oval hole structure, so that the area of the heat dissipation holes 7 is increased, and the cooling area of the edge portion 6 of the sheet material 2 during injection molding is increased.

The area of louvre 7 can directly decide the quantity of seting up in edge portion 6 department louvre 7, when the area of louvre 7 is great, then can suitably reduce the quantity of louvre 7, when the area of louvre 7 is less, then can suitably increase the quantity of louvre 7, but if louvre 7 area is too big, can make the hardness reduction of 2 edge portions 6 of sheet, lead to the cracked condition to appear in sheet 2 easily, if louvre 7 area undersize, louvre 7 is too intensive, cause certain degree of difficulty to the production process of moulding plastics of louvre 7. In the embodiment, the number of the heat dissipation holes 7 is set to three, the three heat dissipation holes 7 are longitudinally arranged at the edge portion 6, and the same distance is kept between the adjacent heat dissipation holes 7, so that the cooling area of the edge portion 6 can be properly increased, the hardness of the edge portion 6 can be ensured, and the sheet 2 is prevented from being broken.

In order to avoid the situation that the heat dissipation holes 7 are inclined to one side of the edge portion 6, the thickness of the sheet 2 on the side is thin, and the sheet 2 is easy to break, the heat dissipation holes 7 are arranged at the middle positions of the edge portion 6, and the center line B of the heat dissipation holes 7 is kept to be coincident with the center line of the edge portion 6, as shown in fig. 3, the distance from the edge line of the heat dissipation holes 7 on one side of the center line B to the edge line of the edge portion 6 is equal to the distance from the edge line of the heat dissipation holes 7 on the other side of the center line B to the edge line of the edge portion 6, so that the sheet 2 can be prevented from breaking, and.

Because the point A of the midpoint between the adjacent heat dissipation holes 7 is located at the inner position of the edge part 6, the heat dissipation speed of the point A is the slowest, and in order to improve the heat dissipation speed of the point A of the edge part 6, as shown in fig. 3, the point A is located on the central line of the heat dissipation holes 7, and the distance from the point A to the edge of the heat dissipation holes 7 is kept equal to the distance from the midpoint to the edge of the edge part 6, so that the heat around the point A can be dissipated through the adjacent heat dissipation holes 7 and the edge of the edge part 6, the point A can dissipate heat quickly and uniformly, the quick cooling effect is realized, the uneven heat dissipation of the internal heat of the sheet 2 in the injection molding cooling process of the sheet 2 can be avoided, the surface foaming and bulging of the.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
