Speed-change and transposition scraping device

Abstract

The invention discloses a speed-change and transposition scraping device which is used for conveying continuous flexible materials at variable speeds and cutting and transposing the flexible materials during the conveying. The speed-change and transposition scraping device comprises a rack, a bearing shaft, an eccentric sleeve, a spatial cylindrical cam, a plurality of reversing frames, negative pressure absorption blocks, a swing rod, a driving disc, a power shaft, a variable-speed transmission mechanism, a scraping mechanism and a reversing negative pressure mechanism, wherein the bearing shaft is arranged on the rack; the eccentric sleeve is eccentrically arranged on the bearing shaft; the spatial cylindrical cam is arranged on the eccentric shaft and is provided with a track groove on the peripheral face; the reversing frames are rotationally arranged on the eccentric sleeve and are distributed along a periphery; the negative pressure adsorption blocks are rotationally arranged on each reverse frame by pivotal shafts and are used for absorbing the flexible materials; the swing rod is arranged between the pivotal shafts and the track groove of the spatial cylindrical cam and is used for driving the negative pressure adsorption blocks to transpose; the driving disc is rotationally arranged on the bearing shaft; the power shaft is arranged on the rack and is used for driving the driving disc to rotate; the variable-speed transmission mechanism is arranged between the driving disc and each reversing frame and is used for driving the reversing frame to reverse at variable speeds; the scraping mechanism is arranged on the rack and is used for cutting the flexible materials; and the reversing negative pressure mechanism is connected with each negative pressure adsorption block through a negative pressure pipeline.

Description

technical field [0001] The invention relates to a variable-speed indexing and scraping device, which is mainly used in the production lines of diapers, diapers, sanitary napkins, etc., and is used for conveying continuous flexible materials at variable speeds and cutting and indexing the flexible materials during conveying. Background technique [0002] In the production process of diapers, diapers, sanitary napkins, etc., continuous flexible materials often need to be cut, indexed, and compounded. The existing cutting mechanism and indexing mechanism are independently installed on the production line, which has the disadvantages of large volume, Disadvantages such as high cost. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art, to provide a flexible material that can be used for variable-speed conveying and to cut and index the flexible material during conveying, so that the flexible material can be eas...
