Slitting transposition variable speed conveying device and method

Abstract

The invention provides a slitting transposition variable speed conveying device and method. The device is used for conveying a flexible material at a variable speed and achieving slitting and transposition in the conveying process. The device comprises a machine frame, a dotted line slitting mechanism, a supporting shaft, a plurality of rotation sleeves, a plurality of first servo motors, rotation frames, negative-pressure absorbing blocks, a cylindrical cam, a swing arm and a rotation negative-pressure mechanism, wherein the dotted line slitting mechanism is used for machining easily-broken dotted lines on the flexible material, the supporting shaft is fixedly arranged on the machine frame, the rotation sleeves are arranged on the supporting shaft in a rotating and sleeved mode, the first servo motors are arranged on the machine frame to drive the rotation sleeves to rotate at a variable speed, the rotation frames are arranged on all the rotation sleeves, the negative-pressure absorbing blocks are arranged on the rotation frames in a rotating mode through a pivoting shaft, the cylindrical cam is arranged on the supporting shaft, the swing arm is connected between the cylindrical cam and the pivoting shaft and used for driving the negative-pressure absorbing blocks to carry out transposition, and the rotation negative-pressure mechanism is respectively communicated with all the negative-pressure absorbing blocks through hoses. The dotted line slitting mechanism is arranged on the input side of the flexible material. The device has the advantages of being simple in structure, accurate in movement, high in adaptability and the like.

Description

technical field [0001] The invention relates to a slitting, indexing, and speed-changing conveying device and method, which are mainly used in the production lines of sanitary napkins, training pants, diapers, etc., to realize variable-speed conveying of flexible materials and to perform indexing and slitting during the conveying process. Background technique [0002] In the production process of paper diapers, diapers, training pants, 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. In order to solve the above technical problems, the Chinese patent No. 201310108830.1 discloses a variable-speed indexing and scraping device, which is used to transport continuous flexible materials at variable speeds and to cut and process flexible materials during transportation. Indexing, including the frame, the support shaft fixed on ...

Problems solved by technology

[0002] In the production process of paper diapers, diapers, training pants, 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. In order to solve the above technical problems, the Chinese patent No. 201310108830.1 discloses a variable-speed indexing and scraping device, which is used to transport continuous flexible materials at variable speeds and to cut and process flexible materials during transportation. Indexing, including the frame, the support shaft fixed on the frame, the eccentric sleeve set eccentrically on the support shaft, the space cylindrical cam with track groove formed on the outer peripheral surface of the eccentric sleeve, and the eccentric sleeve rotatably set A number of revolving frames distributed on the top and around the circumference are rotatably arranged on each revolving frame through a pivot shaft to absorb negative pressure adsorption blocks for flexible materials. The pendulum that presses the adsorption block for indexing, the drive plate that is rotatably arranged on the support shaft, the power shaft that is set on the frame to drive the drive plate to rotate, and is set between the drive plate and each rotary frame for driving the rotary frame The variable speed rotary transmission mechanism, the scraping mechanism set on the frame for cutting flexible materials, and the rotary negative pressure mechanism connected with each negative pressure adsorption block through the negative pressure pipeline, the variable speed indexing scraping device with the above structure , there are disadvantages such as complex structure, difficult maintenance, poor adaptability, etc.
