Two-face coating machine based on synthetic leather processing

Abstract

The invention discloses a two-face coating machine based on synthetic leather processing. The two-face coating machine comprises a sizing agent pool filled with a sizing agent. A first driven compression roller and a first driving compression roller are installed in the sizing agent pool. A through hole is formed in the portion, below a rotating shaft of the first driven compression roller, of the sizing agent pool. A metal pipe is inserted into the through hole and is in sealed connection with the through hole. A high-temperature oil heater is arranged inside the metal pipe. The positions close to the two ends of the metal pipe absorb more heat, and the position close to the center of the metal pipe absorbs less heat. The two-face coating machine further comprises two spray pipes. The spray pipes are provided with spray holes. The spray holes are vertically upward and are aligned with a center shaft, located inside the sizing agent pool, of the first driven compression roller. The high-temperature sizing agent is input through the spray pipes, and the center shaft of the first compression roller obtains the most heat. The two-face coating machine has the beneficial effects that the coating thickness is uniform and energy is saved.

Description

technical field [0001] The invention relates to a double-sided coating machine for processing synthetic leather. Background technique [0002] During the processing of synthetic leather, the base fabric needs to be sent to the slurry tank for soaking. The slurry tank is usually made of stainless steel, and a transmission roller is installed in it. The rotating shaft of the transmission roller is installed on the bracket. The temperature will dissipate heat through the rotating shaft and bracket, and also through the side of the slurry tank where the bracket is installed. Chinese patent discloses CN201410487703.1, a double-sided coating machine for synthetic leather. This coating machine has more transmissions. As a result, the temperature at both ends of the driving roller is lower than the temperature at the center of the driving roller. Correspondingly, the temperature of the slurry near the two ends of the driving roller is lower than the temperature of the slurry near ...

[0002] During the processing of synthetic leather, the base fabric needs to be sent to the slurry tank for soaking. The slurry tank is usually made of stainless steel, and a transmission roller is installed in it. The rotating shaft of the transmission roller is installed on the bracket. The temperature will dissipate heat through the rotating shaft and bracket, and also through the side of the slurry tank where the bracket is installed. Chinese patent discloses CN201410487703.1, a double-sided coating machine for synthetic leather. This coating machine has more transmissions. As a result, the temperature at both ends of the driving roller is lower than the temperature at the center of the driving roller. Correspondingly, the temperature of the slurry near the two ends of the driving roller is lower than the temperature of the slurry near the center of the driving roller. The slurry concentration is lower than the temperature. Affected by this, the processed synthetic leather has a thin center and thick ends, resulting in uneven thickness and affecting product quality.
