Problems solved by technology

However, in the current tanning drum, the feeding is mostly controlled manually. During the manual feeding process, accurate feeding cannot be achieved, and human factors are greatly affected. In the process of large-scale leather processing, it is easy to cause the problem of unstable product quality, and now During the feeding process of some drums, some materials will remain in the feeding pipeline, which will lead to a large error in the actual materials entering the drum

Embodiment 1

[0031] See figure 1 The main body of the present embodiment is a precision control system for the leather process comprising a drum 8 for leather processing, and a feed drum 8 is provided, the feed device comprising a control device 9, a storage The can 1 and the metering device 4, the tank 1, the metering device 4, and the drum 8 are in communication with the tube 2, and the tank 1 is used to store the feedstock, and the tube 2 is used to deliver the storage. The raw material in the can 1 is passed through the meter 4 to the drum 8, and the meter 4 is used to measure the feedstock input to the drum 8, the control device 9 for the meter. Device 4 and the drum 8 are remotely controlled. The original manual feeding is changed to the automatic control system, and the feed amount can be accurately controlled by the metering device 4 according to the process requirements, automatic ingredients and feed. It is possible to accurately adjust the rotation speed and rotation of the drum 8, ...

Embodiment 2

[0040] See figure 2 This embodiment also provides a precision control method for the leather process, applied to the above-mentioned feeding system, including the following steps:

[0041] S1: Open the second electrical control valve 3, control the storage tank 1 to output the material;

[0042] S2: Measure the material, the number of materials reaches the preset threshold, open the first electric control valve 7, and discharge the material into the drum 8;

[0043] S3: The second electrical control valve 3 is closed after the number of materials exceeds the preset threshold, and the cleaning device 5 is opened, and the residual material in the tube 2 is flush into the drum 8.

[0044] See image 3 A precision control device for the leather process is applied to the above-described control system, including a drum 8 for leather processing, the drum comprising a rotating tank 81, and the rotating cabin 81 is provided with a feeding hopper And a control box for accommodating a contro...

Abstract

The invention discloses a precise control system, method and device for a leather making process, and the system comprises a rotary drum for leather processing, the rotary drum is provided with a feeding device, the feeding device comprises a control device, a storage tank and a metering device, and the storage tank, the metering device and a feeding pipeline used for communicating with the rotary drum. The material storage tank is used for storing raw materials, the feeding pipeline is used for conveying the raw materials in the material storage tank into the rotary drum through the metering device, the metering device is used for metering the raw materials input into the rotary drum, and the control device is used for remotely controlling the metering device and the rotary drum. An automatic control system is used for replacing original manual feeding, automatic burdening and feeding can be achieved according to process requirements, and meanwhile the feeding amount can be accurately controlled through a metering device. The rotating speed and the rotating time of the rotary drum can be accurately adjusted and can be preset according to the process.

Description

Technical field [0001] The present invention relates to the field of tangent, and more particularly to a precision control system, method, and apparatus for a leather process. Background technique [0002] In tanning refers to the process of processed raw skin. Removal of hair and non-collagen fibers, such as looseness, fixation, and strengthening of leather collagen fibers, and then adding a series of chemistry (including biochemistry), mechanical treatment. The process of tanning process is usually divided into four stages of preparation, tanning, wet dyeing and dry state (reason). The tanning process uses the most equipment to be drum, immersion, fumding, hair removal, softening, dip acrylic, tanning, dyeing, fatty fat, etc., through the drum, through the mechanical effect of the drum, promote various chemicals Uniform penetration of materials, complete the chemical effect of preparation to skin. [0003] During the current leather, the absolute processing time of leather in t...
