Sliding base specially used for BOPET (biaxially-oriented polyethylene terephthalate) sheet

Abstract

The invention discloses a sliding base specially used for a BOPET (biaxially-oriented polyethylene terephthalate) sheet, which comprises a left side plate, a right side plate, a guiding plate, an upper fixing plate, a front fixing plate, a rear fixing plate, a adjusting screw rods, a lower sliding rail, an upper sliding rail, an oil receiving disc, a positioning disc and a clamp guiding rail. The left side plate and the right side plate are respectively provided with a rolling shaft; the guiding plate is arranged in the middle of the rolling shafts; the upper fixing plate, the front fixing plate and the rear fixing plate are used for fixing the left side plate and the right side plate; the adjusting screw rods are arranged in the centers of both the front fixing plate and the rear fixing plate; the lower sliding rail is arranged on the upper fixing plate; the upper sliding rail is arranged on the lower sliding rail; the oil receiving disc is arranged on the upper sliding rail; the positioning disc is fixed on the oil receiving disc; the positioning shaft is fixed on the positioning disc; and the clamp guiding rail is fixed on the positioning shaft and the positioning disc through a pressing disc. The overall longitudinal and latitudinal adjustment of the clamp guiding rail can be realized, and the latitudinal centering bidirectional adjustment can be realized. Because of the longitudinal and latitudinal precision guiding, the guiding rail can slide dynamically, stably and reliably. In addition, due to the arrangement of the oil receiving disc, the lubricating oil can be recycled. The sliding base has the characteristics of convenience of adjustment, simple structure and low failure rate and is easy to operate.

Description

technical field [0001] The invention relates to a plastic film stretching device, in particular to a special sliding seat for BOPET bidirectionally controlled stretching sheet. technical background [0002] The special sliding seat for BOPET biaxially oriented sheet is suitable for the fixing of the fixture guide rail on the plastic film biaxially oriented sheet equipment, and the horizontal and vertical adjustment of the guide rail. The lateral direction of the guide rail can realize the two-way adjustment of the centering and the rotation adjustment of the connection between the guide rails. At the same time, the guide rail can be lengthened and shortened according to different process requirements. [0003] At present, the special sliding seat structure for BOPET biaxially stretched sheets is a fixed assembly without horizontal and vertical adjustments, and the sliding seat cannot be adjusted. Effectively overcome thermal expansion and contraction, so that the guide rail...

AI Technical Summary

Problems solved by technology

[0003] At present, the special sliding seat structure for BOPET biaxially stretched sheets is a fixed assembly without horizontal and vertical adjustments, and the sliding seat cannot be adjusted. Effectively overcome thermal expansion and contraction, so that the guide rails cannot be freely expanded and contracted, resulting in thermal stress between the guide rails, affecting the normal operation of the fixture on the guide rail, resulting in jamming and broken fixtures during the production process of the fixture. Serious It affects the production. At the same time, the connection between the guide rail and the guide rail is fixed, and the clamping width of the fixture cannot be adjusted at any time. The adjustment time takes up a lot of production process, the production efficiency is low, the positioning is not accurate, and the scrap rate is high.
