Problems solved by technology
[0004] 1. It is difficult to meet the different pressing force requirements of different hardness, thickness and width of rubber materials
The actual use results show that this structure is sufficient for thin films, and air bubbles are prone to appear in products with large thickness; the films with small hardness are fully pressed, and the films with high hardness are not firmly pressed, requiring human intervention in the next process and repeated pressing combine
[0005] 2. Poor reliability and stability
The compression spring will be fatigued and deformed after repeated long-term use, and it is frequently necessary to manually lock and adjust the pre-compression force, which cannot meet the production requirements of the current automated formula management
[0006] 3. Low production efficiency
In the independent production line of pressing configuration, the film that has been guided needs to be replaced frequently, and the production line must operate intermittently, resulting in low efficiency
[0007] 4. Workers operate with high labor intensity
Since all the multi-layer films are roll-changing guides, workers need to change the rolls every ten minutes, and the more lamination layers, the greater the workload required for replacement.
[0008] 5. There are potential safety hazards in operation
The rigid pressing form pressing device must be designed as an open type to facilitate maintenance and manual adjustment of different films. This structure has greater operational safety.
[0009] For the wide-width strong conveyor belt industry, the calendered width of the film is much larger than the product width of the tire industry, and the pressing width is in the range of 1600mm to 3000mm. At the same time, the thickness and hardness of the film vary greatly. The original technical solution of the strong conveyor belt industry is used. It cannot be applied to the multi-layer film lamination technology in the wide-width strong conveyor belt industry

Abstract
The invention discloses a multilayer film online automatic edge aligning flexible pressing forming system, and aims at meeting different pressing force production requirements required by different film material varieties, hardness, thickness and width; the automation level and the production efficiency are improved. The system comprises a slave film uncoiling guide device, an active and slave film edge aligning device and an active and slave film pressing device. A CCD (Charge Coupled Device) camera fully automatic edge aligning detection technology is used, so that the edge line of the slave film and the edge line of the reference film are automatically aligned; a servo control technology is used; the slave film is subjected to position transverse moving / deflection correction in real time; a laser mark line is used for automatically positioning the initial position of a slave roll; in a pressing system, a hydraulic servo technology is used for controlling the online constant bonding force pressing of the multilayer film; the automatic configuration pressure giving can be realized according to different film combinations; meanwhile, the pressing forming on the films with different thickness can be realized by using lead screw for regulating the distance. The multilayer film online automatic edge aligning flexible pressing forming system has the advantage that the pressing requirements of the multilayer film under different technical conditions at present can be met.
Description
technical field [0001] The invention relates to a multi-layer film pressing and forming production technology, specifically a multi-layer film online automatic edge-aligning flexible pressing and forming system, which is mainly used in the wide-width strong conveyor belt industry, and realizes online automatic flexible forcing of multi-layer films Compression molding. Background technique [0002] The multi-layer film pressing and forming process is an indispensable process for the strong conveyor belt. Due to the large conveying load, the strong conveyor belt is generally composed of multiple layers of rubber with different material properties bonded longitudinally to the steel cord core. The middle part of the conveyor belt is a steel cord. The upper and lower sides of the steel cord are at least designed with a core rubber layer and a surface rubber layer. In order to improve the service life and buffer performance, a transition layer is generally laid between the core ru...
