Problems solved by technology

The adhesive is applied twice, one is to increase the processing flow and make the method more cumbersome; the other is to prolong the processing time and reduce the work efficiency
[0005] The rubber outer ring is formed by injecting glue on the periphery of the wheel core. First, the injection of the automatic glue injection machine will easily affect the uniformity of the rubber adhesive, resulting in no ironing between the rubber and the wheel core, reducing the performance of the roller, and increasing waste products. Second, holes are left on the rubber outer ring obtained through injection, which affects the appearance of the product

Embodiment 1

[0045] A preparation method for a roller of a flatbed vehicle, comprising the steps of:

[0046] Select nylon 1013B as the raw material of nylon wheel core 1, and dry the raw material at 120°C for 4 hours; use the plastic injection molding machine to inject the dried raw material (injection pressure is set to 80, the injection speed is set to 60, the material Nozzle 240°, zone 1 220°, zone 2 225°, zone 3 235°), after the injection molding is completed, press full pressure for 20s for molding. Then the obtained nylon wheel core 1 is cooled for 50 seconds, and the cooled nylon wheel core 1 is trimmed to remove flash and burrs to obtain a finished nylon wheel core 1 .

[0047] Use an organic solvent such as acetone or toluene to clean the surface of the nylon wheel core 1. After drying, apply an adhesive. The thickness of the adhesive is 0.05 mm. The outer ring is wrapped with rubber strips (rubber is natural rubber, with a rubber content of 20%), and the rubber strips are wound...

Embodiment 2

[0062] A preparation method for a roller of a flatbed vehicle, comprising the steps of:

[0063] Select nylon 1013B as the raw material of nylon wheel core 1, and dry the raw material at 110°C for 5 hours; use the plastic injection molding machine to inject the dried raw material (injection pressure is set to 80, the injection speed is set to 60, and the material Nozzle 240°, zone 1 220°, zone 2 225°, zone 3 235°), after the injection molding is completed, press full pressure for 20s for molding. Then the obtained nylon wheel core 1 is cooled for 50 seconds, and the cooled nylon wheel core 1 is trimmed to remove flash and burrs to obtain a finished nylon wheel core 1 .

[0064] Use an organic solvent such as acetone or toluene to clean the surface of the nylon wheel core 1. After drying, apply an adhesive. The thickness of the adhesive is 0.05 mm. The outer ring is wrapped with rubber strips (rubber is natural rubber, with a rubber content of 20%), and the rubber strips are w...

Abstract

The invention discloses a rolling wheel for a flat car, a preparation method of the rolling wheel and the flat car. The preparation method includes the steps that an adhesive is smeared on the outer ring of a nylon wheel core, and then a rubber strip is pasted on the outer ring of the nylon wheel core to obtain a rubber layer, wherein the rubber strip is uniform in thickness, the width of the rubber strip is roughly equal to that of the nylon wheel core, and the thicknesses of different parts of the rubber layer are roughly equal; the nylon wheel core coated with the rubber strip is vulcanized and trimmed, and the rolling wheel is obtained. It can be guaranteed that the bonding strength between the rubber outer ring prepared after vulcanization and the nylon wheel core is more uniform, the overall strength of the obtained rolling wheel is improved, and thus the service life of the rolling wheel is prolonged; it is avoided that an existing adhesive injection method influences the uniformity of an adhesive, and consequently fitness between rubber and a wheel core is poor, and the finished product rate of the rolling wheel is increased.

Description

technical field [0001] The invention relates to a roller, in particular to a roller used for a flatbed vehicle, a preparation method thereof and a flatbed vehicle. Background technique [0002] The rollers of existing flatbed vehicles generally include a wheel core and a rubber outer ring. The wheel core and the rubber outer ring are produced separately, and then the rubber outer ring is placed on the outer ring of the wheel core to form a roller. The wheel core and the rubber outer ring are separated. , The rubber outer ring is sleeved on the outer ring of the wheel core, and it is easy to fall off, which not only easily causes damage to the rubber outer ring and the wheel core, reduces the life of the roller, but also easily deforms under heavy loads, limiting the increase in the load-bearing capacity of the flatbed. [0003] Although there is a patent that after the rubber adhesive is applied twice on the prepared plastic wheel core, the wheel core is put into the mold ca...
