Web Guiding System
Web Guiding System
Techmach web guiding system consists of controller, sensor, actuator and guide mechanism. Those four parts compose a close loop control system. Web guiding sensor detects the position of web edge, finds deviation amount between actual position and set position, converts deviation amount to proportional voltage signal and sends the voltage signal to controller. After amplification and calibration, controller transfer signal to actuator. According to the signal, guide mechanism makes correction action guiding material to the preset position.

Thickness Measurement System
Thickness Measurement System
Techmach laser thickness measurement system is mainly composed of upper computer and control unit, thickness measuring unit and detector moving mechanism. When the thickness is measured, the upper and lower laser displacement sensors shoot at each other and measure the position of the upper surface and the position of the lower surface respectively, calculated to be measured body thickness.

Corona Control System
Corona Control System
Corona treatment system is a specialized system for the surface treatment of materials, widely used in printing and packaging industries, which makes the surface of the substrate has a higher adhesion, the principle is the use of high-frequency high voltage to impact on the plastic processed surface, resulting in low-temperature plasma, producing free radicals on the plastic surface and making the polymer cross-linked. Roughening of the surface and increasing its wettability to polar solvents - these ions are impacted and penetrated into the surface of the body to be imprinted to destroy their molecular structure, thereby oxidizing and polarizing the surface molecules to be treated, attacking the surface by ion shock, Resulting in increased substrate surface adhesion.

Vision Inspection System
Vision Inspection System
Due to the mechanical error of the production equipment itself, raw materials, foreign body and production management and other reasons, it may cause defects and defective products in the production of sanitary products and their raw materials. Manual removal of waste is not only high cost, but also affects production efficiency. Techmach intelligent vision inspection system can detect impurities on the products accurately and comprehensively, for example, mosquitoes, hair, resin, stains, oil points, etc. It also can detect the quality of the product itself, like folds, leakage of cotton, and materials are not neat, etc. System operation is simple, full-featured, can be perfectly applied for sanitary towels, pads, diapers, mattresses and other sanitary product equipment, making it better to improve the market's reputation, reduce labor costs, improve product quality and production efficiency.
