Description

Technical Field

[0001] The utility model relates to the technical field of signal interference prevention, in particular to a texturing machine signal interference prevention device. Background Art

[0002] HY-9 texturing machine is a fully automatic texturing machine, which has multiple rollers and multiple speed sensors. The speed sensor control principle diagram on the texturing machine is as follows: Figure 1 As shown. However, during the production process, it was found that due to the interference of unknown signal sources, the HY-9 texturing machine frequently had speed interference fluctuations, and the fluctuation interference would generally recover automatically in about 5 seconds. When speed interference fluctuations occurred, as long as one of the speed sensors detected that the fluctuation value exceeded the deviation value, the texturing machine would automatically cut the silk thread, causing production problems. In the actual test process, it was also found that the actual conveying speed of the texturing machine did not change, indicating that the actual conveying speed was basically stable. Therefore, it was necessary to shield or weaken the interference signals of each speed sensor on the texturing machine so that the equipment could produce stably. For this problem, our company and the manufacturer have also conducted multiple debugging, including the replacement of the speed shielding line and the rearrangement of the wiring, but none of them eliminated or reduced the problem of interference frequency. Summary of the invention

[0003] In order to solve certain technical problems existing in the prior art, the purpose of the present application is to provide a texturing machine signal anti-interference device, which can prevent the sensor signal line from frequently experiencing speed interference fluctuations exceeding the deviation value and causing automatic wire cutting, thereby greatly reducing the probability of automatic wire cutting of the machine and improving the stability of the machine operation.

[0008] Preferably, the second anti-interference structure adopts a filter capacitor.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0016] Below, the present application is further described in conjunction with the accompanying drawings and specific implementation methods.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0019] like Figure 2 As shown, a signal anti-interference device for a texturing machine comprises a plurality of speed sensors 3 arranged in parallel on the texturing machine, a signal line 1 connected to the speed sensors 3 for testing the wire speed, and a speed power line 5 for supplying power to each of the speed sensors 3, wherein a first anti-interference structure 4 is provided on the speed power line 5, and a second anti-interference structure 2 is provided on the signal line 1 of each of the speed sensors 3.

[0020] When improving the problem of frequent speed interference fluctuations in the HY-9 texturing machine, based on the original circuit, a first anti-interference structure 4 is installed at the front end of the total speed power line 5 for the power supply of each speed sensor 3, and a second anti-interference structure 2 is installed on the signal line 1 of each speed sensor 3. The power bus is prevented from interference by the first anti-interference structure 4, and the speed signal line 1 of each speed sensor 3 is prevented from interference by the second anti-interference structure 2. After the anti-interference devices are installed in two places, the fluctuation interference frequency and amplitude of each sensor are effectively reduced, the probability of automatic wire cutting of the machine is greatly reduced, and the production efficiency is improved; it can effectively prevent the fluctuation from exceeding the deviation value and causing automatic wire cutting, solve the problem of frequent automatic wire cutting in the HY-9 texturing machine due to frequent speed interference fluctuations, and make production stability higher.

[0021] Further improvement is as follows: Figure 3 As shown, the first anti-interference structure 4 includes a magnetic ring 6 and a strap 7 for fixing the magnetic ring 6 . The magnetic ring 6 is arranged at the front end of the bus of the speed measuring power line 5 , and the positive and negative poles of the speed measuring power line 5 pass through the inner hole of the magnetic ring 6 .

[0022] The first anti-interference structure 4 is composed of a magnetic ring 6 fixed to the speed measuring power line 5 by a binding strap 7. During installation, the positive and negative power lines of the speed measuring power line 5 pass through the inner hole of the magnetic ring 6 and are then fixed to the speed measuring power line 5 by the binding strap 7. The entire structure is simpler and the production cost is lower.

[0023] A further improvement is that the outer diameter of the magnetic ring 6 is 1 to 2.5 cm, and the binding tape 7 is a cable tape.

[0024] The outer diameter of the magnetic ring 6 is 1 to 2.5 cm, and its volume is smaller. After installation, it will not cause too much wiring interference to the speed measuring power line 5. Generally, the outer diameter of the magnetic ring 6 is 2 cm, and the binding strap 7 uses cable tape, which is more convenient when fixing the magnetic ring 6. Generally, after being fixed, the angle between the magnetic ring 6 and the speed measuring power line 5 is greater than 70°, which can make it more effective in anti-interference.

[0025] A further improvement is that the second anti-interference structure 2 uses a filter capacitor; the capacity of the filter capacitor is 0.1-0.2uf.

[0026] The second anti-interference structure 2 uses a filter capacitor, which has a lower cost for structural improvement, especially the capacity of the filter capacitor is 0.1uf, which is more versatile and smaller in size. By adding a filter capacitor to the signal line 1 to shield interference, the probability of automatic wire cutting is greatly reduced.

[0027] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
