Abstract

The invention relates to an electromechanical integrated device and an extrusion method for extruding rubber products. The electromechanical integrated device comprises an extrusion head, a receiving device, a continuous balance weighing device, a width measuring device and a PLC system; an extrusion die is arranged on the extrusion head; one side of the receiving device is close to the extrusion die and the continuous balance weighing device and the width measuring device are arranged on the other side of the receiving device; a die speed measuring roller for measuring extrusion speed is mounted on the outer side of the extrusion die; the output ends of the continuous balance weighing device and the width measuring device are connected to the input end of the PLC system; the output end of the PLC system is connected with the extrusion die and the receiving device. With a main control ring and an auxiliary control ring, the electromechanical integrated device is capable of eliminating fluctuation caused by foreseeable errors such as the inherent error of the device and the property change of rubber and the weight and width fluctuation of the rubber products caused by other unforeseeable errors, and therefore, the disturbance resisting ability and the extrusion accuracy of the electromechanical integrated device and the extrusion method are improved.

Description

technical field

[0001] The invention relates to an extruding device and an extruding method, in particular to an electromechanical integration device and an extruding method for extruding rubber products. Background technique

[0002] In the prior art, the main rubber parts in tire products need to be produced by extrusion process, and the extrusion process of rubber products is an indispensable process link in the production of automobile tires. The quality and precision of extruded products directly affect the final quality and precision of tire products, and also affect the cost of tire production. The accuracy of the extrusion process has a decisive impact on the quality and precision of the extruded product.

[0003] In the actual extrusion production process, many factors affect the accuracy of the extrusion process, such as: fluctuations in forced feeding due to processing errors of the equipment itself and fluctuations in the amount of glue discharged per revolution...

specific Embodiment approach

[0067] 1. The main ring of speed following servo control: the principle is to detect the linear speed of rubber products in real time through the die-shaped speed measuring roller, which reflects the actual extrusion speed of the product. Using this speed, the linear speed of product extrusion can be compared with that of the rubber product. Direct real-time speed tracking is established between the receiving and receiving line speeds to realize follow-up control to eliminate fluctuations caused by predictable errors such as inherent errors in the equipment itself and changes in rubber properties, so as to ensure accurate extrusion of products. The specific implementation is as follows:

[0068] (1) Parameter setting: set the extruded rubber product to be a synthetic rubber sheet of 100mm×1mm, set the standard weight value g per meter of the rubber product to 0.1kg, and set the standard width value to 100mm. The extrusion line speed of the rubber product is 35m / min, and the no...
