Description

Technical Field

[0001] The utility model relates to a width measuring device, in particular to a quick-detachable tow width measuring device. Background Art

[0002] In the production process of fiber tows, the maximum spinning speed of the tows can reach 600m / min. Therefore, under the condition of continuous production of tows, the width of the tows is prone to large deviations due to the back-and-forth fluctuations of the swinging trolley, thus affecting the overall uniformity of the tows. In order to control the stability of the swinging of the tows, on-site operators generally need to measure and manage the width of the tows to ensure the production quality of the tows.

[0003] Chinese patent CN218723888U discloses a device for measuring the width of a tobacco tow. A camera is arranged below the tow feeding port. Before the tow enters the swinging frame, the camera takes a picture of the tow to obtain the width data of the tow. However, the device has the following problems:

[0004] (1) The device starts the camera by triggering a sensor set at a fixed position, and then takes a picture of the silk bundle to obtain its width value. The sensor is generally located at a height of about 3m above the top of the swing wire frame (i.e., the upper part of the swing wire machine), and multiple people are required to cooperate in triggering the operation; and the position of the sensor is fixed on the swing wire machine. Therefore, it is impossible to measure the silk ribbon width of other designated machines except this fixed position, which results in the position, scope of use, and location of width measurement being limited.

[0005] (2) Since the device is installed as a whole at the feeding port of the swing wire arm, it cannot be disassembled during the measurement process and can only be dismantled after the production is completed. As a result, the feeding port of the swing wire arm needs to maintain a continuous load for a long time during the production process. The weight of the whole device is about 3 kg. In the industrial continuous production process, the production cycle of a complete silk package is 6 hours. Therefore, its existence will have an adverse effect on the overall swing of the silk bundle, thereby increasing the measurement error.

[0006] (3) The detection data of the device needs to be coordinated with the timing equipment, but in actual application, it is mostly measured manually. This timing method is prone to errors, thus affecting the measurement accuracy. In addition, when acquiring and processing data, the data is generally retrieved from the camera end and then processed accordingly, and the data cannot be directly acquired from the site. Therefore, the data processing is delayed and discontinuous, and the changes and fluctuations in the width of the tow cannot be understood in the first place.

[0007] (4) The device is connected mainly by connecting wires and network cables at the camera end, and connecting to the sensor through network cables. The large number of overall lines makes the connection process more complicated. The network cables and wires need to pass through the longer swing arm channel when the equipment stops, and the lines need to be laid in the swing machine tank chain. Therefore, it is easy to cause waste wire to the production site, and after the measurement is completed, it is inconvenient to remove the lines, which increases the workload of the operator.

[0057] like Figure 6 As shown, the lower side of the back plate 11 is provided with a second mounting groove 14 for mounting the second cross beam 5, and the second mounting groove 14 is adapted to the cross-sectional shape and size of the second cross beam 5. Generally, the size of the second mounting groove 14 can be designed to be 1 mm larger than the cross-sectional size of the second cross beam 5, thereby improving the degree of fit when installing with the second cross beam 5. The bottom of the back plate 11 is provided with a threaded hole 15 extending from bottom to top, and the second cross beam 5 is fastened to the lower end of the back plate 11 by passing the top screw through the threaded hole 15. When the back plate 11 is clamped with the connecting plate 6, the end of the second cross beam 5 passes through the second mounting groove 14 on the back plate 11 and abuts against the lower side of the connecting plate 6. According to the use requirements, the back plate 11 and the second cross beam 5 can also be designed as an integrated structure, which is more convenient for installation.

[0058] The first adjustment plate 7 is an L-shaped plate structure, wherein a group of through holes 71 are provided on the horizontal adjustment surface, and a group of first adjustment holes 43 corresponding to the through holes 71 are provided on the first crossbeam 4; the first adjustment plate 7 can be installed on the first crossbeam 4 by using bolts to pass through the through holes 71 and the corresponding first adjustment holes 43 in sequence, and the installation position of the first adjustment plate 7 on the first crossbeam 4 can be adjusted by adjusting the position of the bolts in the first adjustment holes 43, thereby adjusting the distance between the reflector 3 and the tow. The group of first adjustment holes 43 described in this embodiment refers to two rows of first adjustment holes, each row of which can be a long hole or multiple through holes.

[0059] A group of second adjustment holes 72 are provided on the vertical adjustment surface of the first adjustment plate 7. Bolts are passed through the second adjustment holes 72 to install the reflector 3 on the first adjustment plate 7. The installation height of the reflector 3 can be adjusted by adjusting the position of the bolts in the second adjustment holes 72.

[0060] In this embodiment, the first adjustment hole 43 and the second adjustment hole 72 are both elongated holes.

[0061] The second cross beam 5 is also provided with a weight-reducing hole 51, so as to reduce its own weight and further reduce the load on the feed opening.

[0062] The camera 2 is installed below the end of the second beam 5 away from the discharge port through the second adjustment plate 8. The structure of the second adjustment plate 8 is the same as that of the first adjustment plate 7, and is also an L-shaped plate structure, wherein the horizontal adjustment surface is installed below the second beam 5, and the specific installation position can be adjusted; the vertical adjustment surface is used to install the camera 2, and the installation height of the camera 2 on the other adjustment surface can be adjusted to ensure that the height of the camera 2 corresponds to the reflector 3, thereby improving the extraction quality of the tow information.

The measuring device can be installed before production, which takes about 1 minute and is relatively convenient. Moreover, the installation height of the reflector 3 and the camera 2 and the distance between them and the tow to be measured can be adjusted, so that different types of tows and different positions of the tows can be quickly measured.

[0064] During the test, the user manually turns on the test switch on the host 1, and the camera 2 starts taking pictures for testing. Before the test, the simulated motion path can be set according to the motion parameters of the swing wire machine. At the same time, the start program can be controlled by the host 1, and it can be started and terminated at any time, thereby improving the controllability of the measurement, and by adjusting the position of the camera 2 and the reflector 3, accurate measurement of the specified position can be achieved.

[0065] After the measurement is completed, the main body 1, the second beam 5 and the camera 2 can be quickly removed from the first mounting groove 62 of the connecting plate 6. The disassembly process is simple and convenient. After that, the connecting bolts of the connecting plate 6 and the baffle 41 are loosened, and the connecting plate 6, the first beam 4 and the reflector 3 connected to the first beam 4 can be quickly disassembled, thereby realizing the rapid disassembly of the whole device, thereby reducing the load of the feeding port, and at the same time does not affect normal production.

[0066] Fig. 9The data display image is a data diagram of the actual width of the on-site swing wire, which circulates 19 times in total in the swing wire frame. The swing wire arm in the on-site swing wire frame is fixed to reciprocate 19 times per layer. In view of this reality, the width fluctuation data is consistent with the motion trajectory of the swing wire arm, and the width of the on-site ribbon fluctuates according to the reciprocating swing wire.
