It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

An endless conveyor belt comprises a tubular seamless skeleton fabric 10 and a PU layer 11 coated on the surface of the skeleton fabric 10. The thickness of the PU layer 11 is 0.3 mm-0.5 mm, and the PU layer 11 is positioned on the outer surface of the framework fabric 10, as shown in figure 1.

The skeleton fabric 10 is a tubular fabric, and the surface and the reverse side of the tubular fabric have the same weave structure, and are both 1/1 plain weaves.

The knitting form of the rib fabric 10 is a loop as shown in fig. 2, and fig. 1 and 2 are schematic views from the same perspective. The skeleton fabric 10 corresponds to an upper and a lower fabric layers, and both edges of the two fabric layers are continuously joined together to form a tubular fabric. The upper layer fabric is formed by weaving surface warps 2 and surface wefts 1, the lower layer fabric is formed by back warps 4 and back wefts 3, and the density of the surface/back warp weft yarns is as follows: 30 x 40 per inch.

The specification of surface warp 2/inner warp 4 yarn: 0.3mm ultra-low shrinkage polyester monofilament. The face warp 2/back warp 4 provides the loop-shaped carcass fabric 10 with stiffness in the cross-machine direction of the base material. The cross direction is the width direction of the scrim 10, or the direction parallel to the center line of the loop in which the tubular scrim is located.

The specification of surface weft 1/inner weft 3 yarn: 1000D ultra-low shrinkage polyester filament, twisting: 100 revolutions per meter. The surface weft 1/the inner weft 3 bear the main strength of the annular strength layer.

The weaving method of the tubular skeleton fabric 10 comprises the following steps: weaving by weft insertion according to the weft insertion sequence by utilizing the weaving characteristic of a shuttle loom, wherein when the surface weft 1 is inserted, the surface warp 2 is divided into two layers to form a shed to be interwoven with the surface weft 1, and the inner warp 4 is completely sunk in the lower layer of the fabric and is not interwoven with the surface weft 1; when the inner weft 3 is thrown, the surface warp 2 is fully lifted and is not interwoven with the inner weft 3, and the inner warp 4 is divided into two layers to form a shed to be interwoven with the inner weft 3.

The density at two folding edges of the tubular framework fabric 10 structure is uneven, and the folding edges have obvious creases, so that the crease effect can be reduced by adjusting the warp density at the folding edges.

A method of manufacturing the above-described endless conveyor belt, as shown in fig. 3, includes the steps of:

step S1: the skeleton fabric 10 is annularly shaped.

In this step, the tubular or annular skeleton fabric 10 is stretched by the two position-adjustable tension rollers 5, the crease of the skeleton fabric 10 base material is eliminated, the surface smoothness is improved, and the size of the skeleton fabric 10 as the reinforcement can be finely adjusted by adjusting the tension rollers 5.

The setting parameters are as follows: the temperature was 180 ℃ and the temperature was heated by an infrared heater 7 with a tension of 20 kg.

Step S2: the skeleton fabric 10 is impregnated with PU glue.

In this step, the skeleton fabric 10 is held on the tension roller 5, the PU glue is coated on the surface of the skeleton fabric 10, and the PU glue is uniformly coated by the scraper 6.

The glue curing temperature is 160 ℃, the glue is heated by the infrared heater 7, the framework fabric 10 can fix the yarns of the fabric and prevent the yarns from moving by dipping the PU glue, so that a stable reinforcement is further provided for the conveying belt, and the PU glue is used for bonding the PU layer 11 on the surface.

Step S3: the surface of the skeletal fabric 10 is coated with PU and plasticized.

In the step, the coated PU coating material can be powdery, and the PU coating material is heated and plasticized by an infrared heater 7 at a plasticizing temperature of 165-180 ℃. Meanwhile, the PU layer 11 is compressed by the compression roller 8, and the compression roller 8 plays a role in controlling and adjusting the thickness of the coated PU layer 11.

In addition, in this step, the uniformity of the belt body is monitored and controlled in real time by the weight on-line monitoring system 9, so that the thickness error of the belt body is controlled within a range of ± 5 threads, wherein 1mm is 100 threads. The precision and the uniformity of the thickness of the belt body are improved.

The weight on-line monitoring system 9 weighs the framework fabric 10 supported on the tension roller 5, specifically, the weight on-line monitoring system 9 supports and weighs the fabric with a fixed area (such as 1 square meter), that is, the change of the weight monitored by the weight on-line monitoring system 9 can reflect the change of the thickness of the fabric. Along with the rotation of the tension roller 5, the fabric is driven to run, and the weight online monitoring system 9 is used for dynamically monitoring the whole fabric. When the weight monitored by the weight on-line monitoring system 9 fluctuates, the thickness of the fabric section is represented to be uneven. During specific operation, when the weight fluctuation range monitored by the weight online monitoring system 9 exceeds a set value, the gap between the scraper 6 and the framework fabric 10 can be adjusted to control the coating amount of the PU powder, so that the adjustment and control of the fabric thickness are realized, and the processed fabric thickness is more uniform.

Step S4: and (5) cutting and forming. Cutting into required width size.

Finally, it must be said here that: the above embodiments are only used for further detailed description of the technical solutions of the present invention, and should not be understood as limiting the scope of the present invention, and the modifications and adjustments made by those skilled in the art according to the above-mentioned contents of the present invention are all included in the scope of the present invention.
