1989-1998 is the development period of shoe machine
With the continuous reform and improvement of the market economy, the living conditions of Chinese residents have also been greatly improved. A large number of private shoe-making enterprises have emerged throughout the country, driving the demand for second-hand shoe machine equipment. At the same time, a large number of Taiwan-funded footwear manufacturing enterprises flooded into China during this period, which led Taiwan's shoe machine industry to establish a stronghold in China. However, because the market conditions of early China's market economy were not perfect in many aspects, some Taiwanese capitals entered the Chinese mainland. Shoe companies are not satisfied with the situation.

Front help machine sprayer uneven coating failure repair
There are two ways to apply the inner rubber to the front of the stretch: one is to manually brush the glue, and the other is to automatically spray the glue.
The automatic glue spraying of the front machine is the glue spraying mechanism, and the hot melt glue is conveyed to the surface of the inner bottom sprayer which is in contact with the inner bottom, so that the inner bottom edge is coated with the glue and immediately bonded with the helper foot. If the surface of the glue sprayer is in poor contact with the inner bottom surface, the unevenness of the glue sprayer will be uneven, and the front help will not be stretched on the inner bottom. In addition, the glue transfer mechanism is insufficient in the amount of glue, and the glue cannot fill the surface of the glue sprayer, which may also cause uneven glue application.
The method of processing the front machine is to first remove the glue sprayer from the upper part in the heating state, remove the hot melt glue on the surface, and take the upper surface of the medium shoe last to detect the upper surface of the glue applicator, indicating that the contact is poor. The part is ground and the same curved surface as the last of the shoe last, and the edge of the glue applicator should be slightly smaller than the edge of the shoe. At the same time, the scorch impurities that have been blocked into the glue hole or the glue tank are removed. The front machine reinstalls the glued gluing device to the stretcher, and then adjusts the amount of glue to the maximum amount. The fault of the glue is uneven.
