Embodiment

[0028] Conveyor belt drive belt for paper conveyor of the present invention, such as figure 1 As shown, the conveyor belt includes a middle layer and an upper and lower surface, and the upper and lower surfaces are bonded together with the middle layer through an adhesive. % accelerator, 0.05~0.08% colorant and 40~45% methanol.

[0029] The middle layer is made of polyester material, and the 1% constant elongation strength is 4.5N / mm, which can effectively improve the phenomenon that the belt will lose rotation due to elongation and reduce the transmission efficiency.

[0030] The adhesive used is isocyanate adhesive, which has high bonding strength, and will not cause delamination during operation due to insufficient peeling force, which will affect the service life of the belt.

[0031] Its manufacturing method is as follows:

[0032] Step 1. Polyether-type TPU (thermoplastic polyurethane) and MC6 nylon particles are dried in a drying box (800Kg drying box). After drying, ...

Abstract

The invention relates to a conveying belt for a paper conveyer and a manufacturing method of the conveying belt. The conveying belt comprises a middle layer, an upper surface and a lower surface, wherein the upper surface and the lower surface are adhered to the middle layer through an adhesion agent. Each of the upper surface and the lower surface comprises, by weight, 45%-55% of polyurethane, 45-55% of nylon, 0.3-0.5% of accelerant, 0.05-0.08% of colorant and 40-45% of methyl alcohol. According to the formulation, the manufacturing method of the conveying belt comprises the following steps of drying, mixing, roll manufacturing, galling, application of adhesive, combination of the upper surface, the lower surface and the middle layer and the like. A rubber hardness meter is used for testing the conveying belt manufactured according to the method, a testing result shows that the hardness of the conveying belt is 65-70 degrees, the hardness of the conveying belt manufactured according to the method is smaller than that of general rubber, and therefore the conveying belt manufactured according to the method meets the paper delivery requirement and will not scratch paper. A resistance test result shows that the resistance value of the conveying belt is 2.3*10^8 ohms. The conveying belt for the paper conveyer can well eliminate the electrostatic interaction between the paper and the conveying belt.

Description

[technical field] [0001] The invention relates to a conveyor belt for a paper conveyor and a manufacturing method thereof, in particular to a conveyor belt for a paper conveyor with good wear resistance and antistatic properties and a manufacturing method thereof. [Background technique] [0002] The paper industry generally uses the conveyor belt of the paper conveyor to convey paper, but because the conveyor belt used by the paper conveying machine is made of felt soaked in liquid rubber, the surface hardness is high, and the friction is uneven, resulting in insufficient paper conveying and uneven paper cutting. The biggest disadvantage of the current paper feeding belt is that the surface rubber is aging, cracks appear, and the paper is scratched, which makes the paper waste rate extremely high. [Content of the invention] [0003] In order to solve the problems of high surface hardness, uneven friction, and insufficient paper conveyance in the prior art, the present inve...
