Description

TECHNICAL FIELD

[0001] The utility model relates to a rubber strip width quick adjusting device belongs to rubber strip width quick adjusting device technical field. BACKGROUND

[0002] The rubber strip is generally prepared by an open type plasticating mill, the thickness of the rubber strip is adjusted by controlling the roll spacing of some rolls of the open type plasticating mill, and the width of the rubber strip needs to be controlled by a cutting tool. For the open type plasticating mill, only one rubber strip with a large width is discharged at a time, and the width control is relatively easy. However, for the rubber material of some sealing strips and shock absorbing parts, the open type plasticating mill usually divides multiple rubber materials at the same time. The traditional operation method is to adjust multiple dividing knives connected to the material receiving disc of the open type plasticating mill one by one, measure the distance between each knife, and re-adjust the distance until the width of each rubber strip meets the requirements. At this time, it takes a long time to adjust the width of each rubber strip. For more than three rubber materials discharged at the same time, the overall adjustment time is particularly long, which greatly reduces the production efficiency. Often, the rubber material has already fallen from the open type plasticating mill, but the knife has not been adjusted. After adjustment, the knife is often not tightly fastened due to loosening of the screw during vibration. In addition, the rubber and rubber material cannot be rolled for a long time on the open type plasticating mill, so there is a great risk of burning, dead rubber and other quality problems.
