Packaging steel strip manufacturer: plastic packing belt production with auxiliary profile

Packaging steel strip manufacturer: plastic packing belt production with the introduction of auxiliary plastic packing belt production with auxiliary machinery and production of monofilament, flat wire with auxiliary similar structure, the main cooling water tank, drafting heating device, knurling device, cooling shaping roller group, traction roll and the take-up device. -, cooling water tank cooling water tank is used for packing the strip cooling solidification, welded by steel plate combination, built-in cooling circulating water, cooling water from mold mouth is 150 - 250 mm, cooling water temperature control in the following. Second, the stretching heating device stretching heating device by fast and slow speed of two groups of drafting rollers and heating device. Through two groups of drafting roller speed difference, the heating of the strip tension into product thickness and width you need. Two groups of drafting roller group, driven by a dc motor can according to the draft when drafting work adjust the traction speed difference of two groups of drafting rollers. The strip when drafting the heating method has two kinds: one kind is with 95 - 100 ℃ water heating; Another is to use resistance heating oven, control the temperature section 130 - Between 190 ℃. Temperature should be according to the material performance and the running speed of the strip. Three, embossing device of plastic packing belt stretching to finalize the design after surface pressure patterns, the purpose is to facilitate the connection at both ends and prevent slippage; After a pattern of the surface modification, the product surface is more beautiful. Embossing device has the advantages of simple structure, is consists of a pair of steel decorative pattern roller clearance adjustable up and down. After tensile plastic packing belt pass through between the two pattern roller under certain pressure, take out the surface pattern. Four, after heating roller group after stretch packaging with a certain internal stress exists, products will have certain contraction deformation. Set after heating roller group is in order to increase the packaging belt under tensile condition, cooling cooling time at room temperature, in order to achieve the purpose of its internal stress elimination. Five, take-up device to make the products can be moderately elastic, smooth roll axis, heart asked to drive by dc motor drive, scroll side should also be equipped with friction clutch, in order to make products work coiling speed can along with the increase of winding diameter and speed slow, make rolling take products to maintain a relatively constant tension.
