Description

Technical Field

[0001] The utility model belongs to the technical field of cord fabric production equipment and relates to an expander, in particular to an expander and cord fabric production equipment which can be used for cord fabric generation. Background Art

[0002] The expander device has become an indispensable equipment in the tire cord fabric production line. During the production process of tire cord fabric, the width will be reduced due to dipping, drying and stretching. The expander can adjust the width of the product fabric to meet the specified requirements.

[0003] Since the cord fabric has very high requirements on speed and temperature during the production process, once there is a problem with the expander, resulting in splits on the fabric surface, or the fabric runs off the roller and causes a shutdown, the cord fabric will have to be downgraded or scrapped. Therefore, the stability of the expander is very important to production throughout the production process.

[0004] In the actual production process, due to the difference in the warp density of the cord fabric, when the cord fabric with particularly sparse warp density passes through the photoelectric sensor, the photoelectric sensor cannot correctly identify the width of the fabric, causing the double bending roller to be in an expanded state all the time, which will cause the fabric surface to split. In severe cases, the fabric will run out of the roller and cause equipment damage.

[0005] In view of this, there is an urgent need to design a new expander to overcome at least part of the above-mentioned defects of the existing expander. Utility Model Content

The second worm wheel is disposed in a protection box 26, and a portion of the second worm 18 is nested in a protection rod 22, thereby protecting the second worm wheel and the second worm 18 from working normally and increasing their service life.

[0048] The components and working principles of the second transmission mechanism are similar to those of the first transmission mechanism. The fourth connecting portion 19 and the fifth connecting portion 20 are rotatably arranged on the first supporting mechanism 1, and the sixth connecting portion 21 is respectively connected to the fourth connecting portion 19 and the fifth connecting portion 20; the fourth connecting portion 19 is connected to the second end of the first bending roller mechanism 7, and the second connecting portion 20 is connected to the second end of the second bending roller mechanism 8; the first end of the second worm 18 is respectively connected to the first end of the sixth connecting portion 21 and the fifth connecting portion 20.

[0050] In one use scenario of the utility model, the photoelectric sensor is controlled by analog quantity, and the angle of the double bending roller can be controlled by the forward and reverse rotation of the motor to control the width of the cloth within the set value. When the photoelectric sensor fails, the angle of the bolt bending roller will become smaller, and the cloth will quickly deviate outward. When it hits the limit switch, it will give the motor an open signal to open the bending tube, so that the cloth will reciprocate within a certain width, avoiding the risk of the cloth running out of the roller and being forced to stop.

[0051] Since the photoelectric sensor is an analog output, the limit switch and the photoelectric sensor are connected in parallel, and a 3000 ohm resistor is installed on the limit switch to ensure that when the curtain fabric hits the limit switch, the limit switch can generate an 8 mA current output to the PLC control circuit, and the PLC control circuit controls the expansion motor to rotate. In this way, when the curtain fabric hits the limit switch, the double bending roller opens, and the curtain fabric will not run out of the double bending roller, which can effectively protect the photoelectric sensor bracket and effectively improve the stability of the equipment.

[0052] The utility model further discloses a cord fabric production device, and the cord fabric production device comprises the above-mentioned expander.

[0053] In summary, the expander and the cord fabric production equipment proposed by the utility model can effectively avoid the problem that the expander pulls the cloth out of the double bending roller because the photoelectric sensor cannot detect the cloth, thereby improving the stability of the production line.
