Description

Technical Field

[0001] The invention relates to the technical field of conveyor belts, and more particularly to a mining PVC fabric whole-core conveyor belt and a manufacturing method thereof. Background Art

[0002] Industrial belts can be made of PVC and PU. Since PVC is economical and practical, and has low cost, while PU is expensive, PVC is usually used as a whole-core conveyor belt in industry. Although PVC whole-core conveyor belts are economical and practical, low in cost, easy to process, and have good plasticity; however, due to the low hardness and poor wear resistance of PVC, PVC whole-core conveyor belts have poor wear resistance during use. Frequently damaged PVC whole-core conveyor belts often increase the labor intensity of operators, and production will be interrupted when replacing the conveyor belt, which directly affects the production cost and efficiency of the using company.

[0003] Therefore, how to provide a mining PVC fabric whole core conveyor belt with good wear resistance and a manufacturing method is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0004] In view of this, the present invention provides a mining PVC fabric whole-core conveyor belt with good wear resistance and a manufacturing method thereof.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A mining PVC fabric whole-core conveyor belt comprises: a belt core and an upper belt surface layer and a lower belt surface layer respectively arranged on the upper and lower surfaces of the belt core, wherein a plurality of wear-resistant particles are embedded in the upper belt surface layer, and the upper belt surface layer has a convex texture pattern.

[0007] Furthermore, the wear-resistant grains are diamond sand grains or ceramic sand grains.

[0008] It can be seen from the above technical solution that, compared with the prior art, the present invention discloses a mining PVC fabric whole core conveyor belt, which improves the wear resistance of the upper belt surface layer by embedding wear-resistant particles in the upper belt surface layer, thereby preventing the upper belt surface layer from being worn and damaged quickly when the mineral material is conveyed on the upper belt surface layer, thereby extending the service life of the conveyor belt. In addition, the upper belt surface layer is provided with raised patterns, which can further reduce the smoothness of the upper belt surface layer, facilitate the conveyance of the mineral material on the upper belt surface layer, and prevent the mineral material from slipping off easily.

[0009] A method for manufacturing a mining PVC fabric solid core conveyor belt comprises the following steps:

[0010] Step 1: the belt core is put into a belt core immersion pool, and after exiting the pool, it is put into a plasticizing box for heating and plasticizing;

[0011] Step 2: After leaving the plasticizing box, the belt surface enters the paddle immersion pool again. After leaving the paddle pool, wear-resistant particles are laid on the upper belt surface layer that has been immersed in the paddle;

[0012] Step 3: Then put it into the plasticizing box for heating, so that the wear-resistant particles are bonded to the upper belt surface during the plasticizing process of the paddle;

[0013] Step 4: After leaving the plasticizing box, the strip is put into the ginning machine at the residual temperature. The wear-resistant particles are compacted and embedded into the upper belt surface layer through the rolling of the ginning machine, and a composite upper belt surface layer with a raised pattern and compounded with wear-resistant particles is rolled out.

[0014] The method of the present invention heats and plasticizes the upper belt surface layer embedded with wear-resistant particles through a plasticizing box, utilizes the plasticized upper belt surface layer to enable the wear-resistant particles to be bonded and firmly fixed in the upper belt surface layer, and then uses a embossing machine to roll the upper belt surface layer, thereby compacting and embedding the wear-resistant particles into the upper belt surface layer, making the wear-resistant particles more firmly fixed in the upper belt surface layer and avoiding the wear-resistant particles from falling off.

[0015] Furthermore, through the above steps 2 to 4, a composite lower belt surface layer with wear-resistant particles and raised pattern can be processed on the lower belt surface layer. This can improve the wear resistance and anti-skid property of the lower belt surface layer, so that the lower belt surface layer has a long service life and is not easy to slip when in contact with the rolling, which is beneficial to the conveyor belt conveying.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 and Figure 2The embodiment of the present invention discloses a mining PVC fabric whole core conveyor belt, comprising: a belt core 1 and an upper belt surface layer 2 and a lower belt surface layer 3 respectively arranged on the upper and lower surfaces of the belt core 1, a plurality of wear-resistant particles 4 are embedded in the upper belt surface layer 2, and a raised texture pattern 5 is provided on the upper belt surface layer 2.

[0021] The wear-resistant grains 4 are diamond sand grains, ceramic sand grains or stone sand grains.

[0022] A method for manufacturing a PVC fabric whole-core conveyor belt for mining, comprising the following steps:

[0023] Step 1: The belt core 1 is put into the belt core plastic dipping pool, and after exiting the dipping pool, it is put into the plasticizing box for heating and plasticizing, so that the belt core 1 can be compactly bonded together;

[0024] Step 2: After exiting the plasticizing box, the belt surface enters the paddle immersion pool to form an upper belt surface layer 2 and a lower belt surface layer 3 on the surface of the belt core 1. After exiting the paddle pool, wear-resistant particles 4 are laid on the upper belt surface layer 2 that has been immersed in the paddle.

[0025] Step 3: Then put it into the plasticizing box for heating, so that the wear-resistant particles 4 are adhered to the upper belt surface layer 2 during the plasticizing process of the paddle;

[0026] Step 4: After leaving the plasticizing box, the material is put into the ginning machine at a residual temperature of about 190°. The wear-resistant particles 4 are compacted and embedded into the upper belt surface layer 2 through the rolling of the ginning machine, and a composite upper belt surface layer with a raised pattern 5 and compounded with the wear-resistant particles 4 is rolled out.

[0027] Of course, the composite lower belt surface layer having the wear-resistant particles 4 and the raised texture pattern 5 can also be processed on the lower belt surface layer 3 through the above steps 2 to 4.

[0028] The belt surface of the PVC fabric whole core conveyor belt for mining of the invention is inlaid with wear-resistant particles, which is wear-resistant, has a simple process and low cost, and prolongs the service life of the conveyor belt, reduces the number of conveyor belt replacements and improves efficiency. The cost is basically the same as that of the plastic belt surface of the existing PVC fabric whole core conveyor belt for mining, and overcomes the disadvantage that the plastic belt surface of the existing PVC fabric whole core conveyor belt for mining is not wear-resistant.

[0029] Through the above-mentioned comparison of wear-resistant materials, production processes, and economic costs, this mining PVC fabric solid core conveyor belt is superior to the existing mining PVC fabric solid core conveyor belt. And it can be widely used in mining belt conveyors as a supporting use, and is a necessary conveyor belt for large-volume material transportation in mines.
