Equipment for achieving online traction of extruded plastic sheets

Abstract

The invention discloses equipment for achieving online traction of extruded plastic sheets. The equipment for achieving online traction of the extruded plastic sheets is mainly composed of a rack, a guide pillar, an upper traction device, a lower traction device, an air cylinder, a motor lifting device, a pinch-plate-type traction block and a tensioning mechanism. The upper traction device and the lower traction device both adopt small-power servo motors to drive high-speed-ratio planetary gears, the upper traction device is controlled by the air cylinder to lift, and pressing and loosening of products are rapidly controlled; the lower traction device is controlled by the motor lifting device to lift, the center height of the equipment is adjusted, and production of the products with different thicknesses is met; the pinch-plate-type traction block is convenient to dismount and mount; a traction crawler belt is provided with the tensioning mechanism for positioning and guiding; a guiding device is used for guiding; and a guide sleeve, a connecting frame and the like are arranged on the guide pillar, and it is ensured that the relative positions are maintained to be not changed in the lifting process of the upper traction device and the lower traction device.

Description

technical field [0001] The invention relates to an on-line traction device, in particular to an on-line traction device for extruded plastic sheets, which is mainly used between a shaping table and a cutting machine in an extruded plastic sheet production line. Background technique [0002] In the extruded plastic sheet production line, because the traditional traction equipment uses one or more pairs of rubber rollers, the power of the traction motor is large, the speed ratio of the reducer is large, the volume is large, the traction force is small, and it is easy to slip, and the calculation length is not accurate, resulting in subsequent The length of the products cut by the cross-cutting machine equipment is different; in addition, the rubber roller tractor is prone to dumping, so the frame must be fixed on the ground, and the height from the ground cannot be adjusted. When producing products with different thicknesses, the center height of the cooling and shaping equipme...
