Description

【Technical field】 [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a pad finishing machine used by tire factories. 【Background technique】 [0002] Pad finishing machine is one of the commonly used equipment in tire factories. These equipment generally use traditional technical means. For example, the tension detection is through the weight tension frame structure, and the tension sampling rod and tension sensor (usually using angle sensor) connected; the speed regulation adopts the slip motor speed regulation or the DC motor speed regulation; the edge detection adopts the photoelectric two-position switch to detect the edge.

Problems solved by technology

[0003] The disadvantage of the cloth finishing machine in the prior art is that, using the traditional tension detection technology, there are many moving parts and the volume of the tension sensor is large, especially the tension sensor and the transmission chain move together, which not only increases the instability of the detection system, but also makes the The tension sensor is easy to be damaged: this kind of device mostly uses an angle sensor, and most of them use an infinite potentiometer to detect the angle change of the tension sampling rod, and then detect the tension of the product to be tested, such as a pad

Since the core component of this sensor is the limitless potentiometer, and this component is connected by a chain and a tension sampling rod, the external impact force is often transmitted to this potentiometer due to various reasons on site. Damage; at the same time, since the potentiometer is connected to the tension sampling rod through a chain, the potentiometer moves left and right with the tension sampling rod at any time when the machine is working, which increases the physical wear of the potentiometer and makes its output signal unstable; The speed regulation performance of the traditional slip speed regulation system is not good, and the power factor is very low, which cannot achieve the energy saving effect; although the traditional DC speed regulation system has good speed regulation performance, it is expensive and troublesome in operation and maintenance

The traditional two-position photoelectric edge detection causes the edge detection follow-up mechanism to move from left to right, and the operation is extremely unstable, which leads to uneven rolling and forming of pad cloth or gray cloth
