Description

Technical Field

[0001] This utility model belongs to the field of rope impregnation technology, specifically relating to a device for controlling the amount of adhesive applied to ropes during impregnation. Background Technology

[0002] A common problem encountered during the production of ropes is that during the high-speed passing of the rope through the impregnation tank, a large amount of adhesive is carried away by the rope due to inertia, resulting in excessive adhesive accumulation on the surface of the rope. After high-temperature drying in the oven, defects such as adhesive particles, adhesive spots, and adhesive debris are formed, affecting the appearance and customer processing and use.

[0003] To address these issues, a smooth roller is installed on the upper side of the impregnation tank, with a scraper mounted on one side. The scraper removes excess adhesive from the yarn, ensuring yarn quality. However, this method suffers from two drawbacks: firstly, the contact between the smooth roller and the yarn is relatively short; secondly, the scraper makes rigid contact with both the yarn and the smooth roller, resulting in poor adhesive removal and the continued formation of adhesive particles, spots, and debris after high-temperature drying in the oven. Utility Model Content

[0004] The purpose of this invention is to provide a device for controlling the amount of glue applied to the rope, thereby solving the problem of poor glue application quality in current ropes, which results in defects such as glue particles, glue spots, and glue debris after drying.

[0005] The technical solution adopted by this utility model is a device for controlling the amount of glue applied to the rope during impregnation, including an impregnation machine, an impregnation tank inside the impregnation machine, a first impregnation roller and a second impregnation roller arranged side by side in the impregnation tank, mounting seats respectively on the upper rear sides of the impregnation machine, the mounting seats are vertically upward and one side of the two mounting seats is rotatably mounted on a smooth roller through a bearing seat, one end of the smooth roller extends out of the bearing seat and is connected to the output shaft of a reduction motor, the reduction motor is fixed to the side of the mounting seat through a mounting plate, and a scraper is provided on the other side of the mounting seat, the scraper is U-shaped, the scraper strip is bolted to the front opening of the scraper, the scraper strip is made of silicone, PTFE board or polyurethane foam, and the outer end of the scraper strip extends out of the scraper and contacts the surface of the smooth roller.

[0006] Preferably, there are two light rollers, which are staggered and arranged at the lower rear and upper front of the mounting base.

[0007] Preferably, a fixed seat is also provided on one side of the mounting base, and a grooved roller is fixedly installed on the top of the fixed seat. The grooved roller is located below the front side of the light roller on the upper front side of the mounting base, and the included angle between the grooved roller and the light roller is 30-35°.

[0008] Preferably, the surface of the light roller is chrome-plated, the contact angle between the scraper and the light roller is 30 degrees, and the scraper and the light roller are closely and straightly bonded.

[0009] Preferably, the rear end of the scraper is connected to a round rod via a support rod, and the round rod is bolted to the mounting block on the side of the mounting base. The outer end of the round rod is provided with a threaded rod, and an adjustment plate is provided on the fixed base outward. Multiple connection holes are opened on the adjustment plate along the length direction, and the threaded rod is fastened with a nut after passing through the connection hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by installing a smooth roller above the dip roller, installing a scraper on one side of the smooth roller, and connecting a geared motor to one end of the smooth roller, the motor can actively adjust its speed to control the contact stroke with the yarn. The longer the stroke, the more adhesive adheres to the smooth roller. The scraper equipped on the smooth roller can scrape off the adhesive on the roller, controlling the amount of adhesive applied and achieving a consistent amount of adhesive on the surface of the entire batch of yarn. At the same time, the scraper is equipped with a scraper strip made of silicone, PTFE, or polyurethane foam at the front end of the scraper, which has a certain elastic contact with the surface of the smooth roller, enhancing the effect of scraping off the adhesive on the yarn and the surface of the smooth roller, further reducing the amount of adhesive adhering to the yarn, improving the consistency of the amount of adhesive applied to the entire batch of yarn, and avoiding defects such as adhesive particles, adhesive spots, and adhesive debris after drying.

[0014] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0015] Example 1

[0016] like Figure 1-3As shown, a device for controlling the amount of glue applied to a rope during impregnation includes an impregnation machine 1. The impregnation machine 1 has an impregnation tank 2. A first impregnation roller 3 and a second impregnation roller 4 are arranged side-by-side in the impregnation tank 2. The first impregnation roller 3 is located in front of the second impregnation roller 4. After the rope enters the impregnation tank 2, it first passes through the first impregnation roller 3 and then is led out through the second impregnation roller 4. Mounting seats 5 are respectively provided on the upper rear sides of the impregnation machine 1, i.e., above the second impregnation roller 4. The mounting seats 5 are rectangular and vertically upward. A smooth roller 7 is provided on one side of each mounting seat 5. Both ends of the smooth roller are provided with connecting shafts, and the two ends of the smooth roller are connected to the side of the mounting seat via connecting shafts. The bearing seat 6 is rotatably connected, and the connecting shaft at one end of the smooth roller 7 extends out of the bearing seat 6 and connects to the output shaft of the geared motor 8. The geared motor 8 is fixed to the side of the mounting base 5 by the mounting plate 9. The other side of the mounting base 5 is provided with a scraper 10. The scraper 10 is U-shaped, and the scraper strip 11 is bolted to the front opening of the scraper 10 for easy disassembly, cleaning or replacement. The scraper strip 11 is made of silicone, PTFE or polyurethane foam. The outer end of the scraper strip 11 extends out of the scraper 10 and contacts the surface of the smooth roller 7. The scraper made of silicone, PTFE or polyurethane foam has a certain elastic contact with the smooth roller and the rope, which is conducive to further scraping off the glue.

[0017] After the rope is coated with glue in the glue tank 2, the glue on the surface will stick to the smooth roller 7 when it passes through the smooth roller 7. The speed reduction motor 8 can actively adjust the speed to control the contact stroke with the rope. The longer the stroke, the more glue sticks to the smooth roller 7. The glue scraper equipped on the smooth roller 7 can scrape the glue off the roller to achieve the purpose of controlling the amount of glue applied. The amount of glue on the surface of the entire batch of rope is consistent.

[0018] To adapt to the needs of more products and improve the control of the amount of glue applied to the rope, two smooth rollers 7 are provided. The two smooth rollers 7 are staggered on the lower rear side and the upper front side of the mounting base 5. Both smooth rollers 7 are equipped with a scraper 10. After the rope is drawn out from the second glue-impregnating roller 4, it first passes through the smooth roller located below the rear side of the mounting base 5, and then passes around the smooth roller on the upper front side of the mounting base 5 before being drawn out. A fixing base 15 is also provided on the front side of the mounting base 5. A grooved roller 16 is fixedly installed on the top of the fixing base 15. The grooved roller 16 is located below the front side of the smooth roller on the upper front side of the mounting base 5, and the angle between the grooved roller 16 and the smooth roller 7 is 30-35°. The rope drawn out from the smooth roller passes through the grooved roller branch, which prevents the rope from sticking together, further evens the glue on the rope, and improves the glue impregnation quality of the rope.

[0019] Furthermore, the surface of the smooth roller 7 is chrome-plated and smooth. The contact angle between the scraper strip 11 and the smooth roller 7 is 30 degrees. The scraper strip 11 and the smooth roller 7 are closely and straightly attached to ensure the best scraping effect on the adhesive of the rope.

[0020] The rear end of the aforementioned scraper 10 is connected to a round rod 13 via a support rod 12. The round rod 13 is bolted to the mounting block 14 on the side of the mounting base 5. The outer end of the round rod 13 is provided with a threaded rod. An adjusting plate 17 is provided on the mounting block 14. Multiple connecting holes are opened along the length direction on the adjusting plate 17. The threaded rod passes through the connecting holes and is tightened with a nut. The installation position of the scraper can be adjusted according to the product and the performance of the adhesive, the contact tightness between the scraper and the light roller can be adjusted, and the scraping degree of the thread rope can be adjusted.

[0021] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from its design spirit and principles should fall within the protection scope defined by the claims of the present invention.
