Description

Floating pressure roller structure of strip pulling equipment

technical field

The utility model relates to the technical field of material strip production equipment, in particular to a floating pressure roller structure of material strip traction equipment.

At present, there are many stretching machines used in the production of plastic strips, and the shapes and structures are also very different. The design structure of most existing stretching machines is relatively complicated, with many components, and the cost and space are relatively large. Uneconomical. Chinese patent 201420347675.9 discloses an intelligent automatic strip traction device. The main body of the device is composed of three major parts, the first lifting frame and the second lifting frame, and the connection structure connecting the two lifting frames; its conveyor belt is also divided into three parts. The first and third sections are horizontal sections, and the second section in the middle is an inclined section. The problem with this structure is that the equipment has many components and a complex structure, and the length of the second section of the conveyor track is short, The large slope requires a greater driving force for the second section of the conveyor track, and it uses the sprocket to drive the conveyor track. The metal-to-metal friction between the sprocket and the conveyor track can be used in the process of pulling the plastic strip. The power consumption and noise are relatively large; and, because the rotating roller used to clamp the material strip of this equipment is installed above the water tank through the adjusting screw and the support, once the adjustment is completed, the distance between the rotating roller and the conveyor belt will be relatively fixed. If the conveying track or material strip is uneven, the gap between the roller and the conveying track will be too large or small, resulting in the state of clamping the material strip being too tight or too loose, resulting in deformation of the material strip, or jamming phenomenon, which will affect the quality of the product. The quality and the normal operation of the equipment are affected, and after a period of time, the adjustment screws at both ends of the roller will slowly shift, and at this time it is necessary to stop the machine again for adjustment, which is labor-intensive and time-consuming.
