An indexing variable speed conveying device for flexible materials

Abstract

A transfer speed transmission conveyor device for a flexible material comprises a rack, a spindle rotationally arranged on the rack, a motor connected with and driving the spindle to rotate, a rotary frame fixedly arranged on the spindle, a plane cam fixedly arranged on the rack, a cylinder cam fixedly arranged on the rack, a plurality of adsorption transfer mechanisms circumferentially respectively arranged on the rotary frame, and a rotary negative pressure mechanism connected with each group of adsorption transfer mechanism by a hose. Each adsorption transfer mechanism comprises a rotary drum rotationally arranged on the rotary frame, a swing arm connected between the rotary drum and the cylinder cam for driving the rotary drum to rotate, a lifting rod only movably sleeved in the rotary drum along the axial direction of the rotary drum, a negative pressure adsorption block arranged on the lifting rod, an air supplying lantern ring rotationally sleeving the neck part of the negative pressure adsorption block, a linear guide rail fixedly arranged on the air supplying lantern ring and radially extending along the spindle, a cam bearing arranged on the linear guide rail to be matched with a trail slot of the plane cam and a guide slider arranged on the rotary frame to be glidingly matched with the linear guide rail. The transfer speed transmission conveyor device for the flexible material has the advantages of simple structure, stable action, low cost and the like.

Description

technical field [0001] The invention relates to an indexing and variable-speed conveying device for flexible materials, which is mainly used in the production lines of sanitary napkins, training pants, diapers, etc., and is used for realizing variable-speed conveying of flexible materials and indexing during the conveying process. Background technique [0002] In the production process of diapers, diapers, sanitary napkins, etc., continuous flexible materials often need to be cut, indexed and compounded, and the cutting and compounding positions must have different conveying speeds. The existing cutting mechanism and indexing The mechanisms are independently installed on the production line, which has the disadvantages of large volume and high cost. In order to overcome the above technical problems, the Chinese patent application No. 201310331242.4 discloses a variable speed indexing device of flexible materials, which has simple structure, precise action, Low cost and other...

Problems solved by technology

[0002] In the production process of diapers, diapers, sanitary napkins, etc., continuous flexible materials often need to be cut, indexed and compounded, and the cutting and compounding positions must have different conveying speeds. The existing cutting mechanism and indexing The mechanisms are independently installed on the production line, which has the disadvantages of large volume and high cost. In order to overcome the above technical problems, the Chinese patent application No. 201310331242.4 discloses a variable speed indexing device of flexible materials, which has simple structure, precise action, Low cost and other advantages, but there are still the following disadvantages: the rotation of the drum is guided by the shaft, bushing, linear bearing and ordinary bearing, and driven by the cam bearing and the track groove on the drum, which has complex structure and action Unstable, unable to support high-speed operation and other shortcomings
