Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fabric intelligent detection, in particular, the present application relates to a multi-directional automatic control fabric detection device and detection method. BACKGROUND

[0002] In the process of producing and processing clothes, the performance of the fabric used needs to be tested to obtain the limit data of the performance of the clothes, so as to provide experimental data for the subsequent fabric production process, therefore the detection device for the performance of the fabric is correspondingly generated.

[0003] Most of the detection devices for the performance of the fabric on the market mainly cannot detect the pulling and friction resistance of the fabric, or can set the detection device for the pulling and friction resistance, but need multiple driving forces consuming energy to work, so as to consume a large amount of energy, and in the process of pulling the fabric, the clamping force of the clamping plate cannot increase with the distance of pulling, so that the fabric is easy to separate.

[0004] Nowadays, more and more equipment for detecting the performance of the fabric is developed, for example, the Chinese patent invention patent CN112945783A discloses an energy-saving and environment-friendly device for detecting the pulling and friction resistance of the fabric, which comprises a frame, a motor assembly connected to the rear side of the frame, a first connecting rod fixedly connected to the right side of the first connecting rod, a first moving plate slidably connected to the inner side of the first moving plate, a clamping plate provided on the front side of the first moving plate, a first sliding rod fixedly connected to the upper and lower sides of the first sliding rod, and a first rotating shaft fixedly connected to the right side of the first rotating shaft. The energy-saving and environment-friendly device for detecting the pulling and friction resistance of the fabric drives the first connecting rod to slide left and right, so that the clamping plate drives the fabric to pull back and forth, at the same time, the first rotating shaft drives the friction roller to rotate synchronously, so that the first rotating shaft and the fabric are rubbed with each other, and only one driving force consuming energy is needed, which achieves the effects of detecting the pulling and friction resistance and saving energy and protecting the environment.

[0005] However, the above-mentioned fabric detection device still has the following defects: 1. It can only detect a fixed piece of fabric, and cannot perform online detection during fabric conveying; 2. It still uses rotating shafts to rub with the fabric for detection, i.e. it can only detect one side of the fabric, and cannot detect both sides of the fabric; 3. The detection of pulling performance and friction performance is performed separately, and the performance detection of pulling and friction of the fabric cannot be simulated at the same time; 4. The fabric cannot be detected in multiple directions at the same time.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and efficient multi-directional automatic control fabric detection device and detection method. SUMMARY

[0040] In the present application, the roll diameter of the first transmission roller 1 and the second transmission roller 2 is the same, and the two transmission rollers are arranged in parallel. The first guide roller 51 and the second guide roller 52 are located on one side of the first transmission roller 1 and the second transmission roller 2, so that the fabric cloth 6 has a larger area to contact the first transmission roller 1 and the second transmission roller 2, and the first transmission roller 1 and the second transmission roller 2 are in contact with the same side of the fabric cloth 1, which is hereinafter referred to as the inner side of the fabric cloth.
