How to adjust the front upper machine of the inner support table? Together with Dongguan Qixin mechanical equipment Co., Ltd
2) The starting point of the second stage rising - there are two objectives for the second stage rising of the front upper machine of the inner support platform: 1; It is to prevent the front upper machine of the inner support table from rising to the top at one time, and the upper tension increases suddenly to form damage. 2； Prevent the shoe last from sliding backward due to the increase of upper tension when the front upper machine of the inner support table rises.
The measure is that the front upper machine of the inner support platform first rises to the starting point of the second section to evenly open the upper, then the back heel advances to resist the shoe last to avoid sliding backward, and then the front upper machine of the inner support platform rises to the high point to wait for sweeping and binding. The goal is that the tension of the upper can stably wrap the last, but will not break the upper or make the last slide backward.
1) The effect of the front upper support machine is to support the shoe last, hold the upper close to the last, and then let the broom complete the upper binding measures. In order to meet the above requirements, the front upper support machine has "three points", which can be identified as the lower dead point, the rising starting point and the upper dead point of the second section. It is clarified as follows;
Top dead center - the high point (top dead center) in the task of helping the machine in front of the inner support platform. The fantasy height is to place the last on the front upper machine of the inner support platform, and the bottom of the last is 2-3mm higher than the broom (the sum of the thickness of the midsole cloth and the upper). When the upper dead center is slightly lower, the sweeping knife will sweep the upper or the midsole cloth. On the contrary, if the upper dead center is too high, the result of the upper will be unsafe, and the side feet of the upper will be arc-shaped or raised. Even break the upper.
Lower dead center - normally, adjust the lower dead center after the upper dead center is adjusted. When in standby, the front upper of the inner support platform goes down to the bottom point (bottom dead center). The bottom dead center is the starting height of the upper. The front Deputy must easily extend the upper into the open claws, and the claws clamp the length of the upper (due to the material and design shape of the upper). When the front upper machine of the inner support platform rises and the upper is supported, the tension of the upper is appropriate, so that the upper will not be broken or too loose.
3) Angle of front upper machine of inner support platform - the reasonable angle of front upper machine of inner support platform is to place the shoe last stably on the front upper machine of inner support platform. At this time, the bottom plane of the shoe last must be parallel to the sweeping surface.
Dongguan Qixin mechanical equipment Co., Ltd. - the manufacturer of front upper machine, rear upper machine, front and rear upper machine, Qixin shoe machine and accessories, was established in 1998. It is located in Dongguan City, Guangdong Province, an Asian shoe industry base and a world-famous manufacturing city.
