Variable-speed conveying equipment for flexible materials

Abstract

The invention relates to the technical field of conveying devices, in particular to variable-speed conveying equipment for flexible materials. The equipment comprises a main supporting plate, a fixed middle shaft and rotating plates, the fixed middle shaft is rotatably sleeved with the center positions of the rotating plates, the two ends of each rotating plate are each provided with a negative pressure box, the negative pressure boxes on the rotating plates extend out towards the same side, and the inner side of each negative pressure box is provided with a receding space; the negative pressure box is provided with an induction plate extending towards the interior of the receding hole, one end of the fixing middle shaft extends to the receding space and is provided with a fixing rod located in the receding space, and a proximity sensor is arranged at the end of the fixing rod. The rotating plate adopts a structure that the negative pressure boxes are symmetrically arranged, the gravity center is positioned on the rotating shaft, the operation stability is good, and higher-speed rotating action and variable action with higher acceleration can be realized; the controller monitors the running state of the equipment in real time through the proximity sensor, real-time adjustment and error elimination can be achieved, and it is guaranteed that the equipment works accurately and stably for a long time.

Description

Technical field [0001] The present invention relates to the technical field of the conveying device, in particular to a flexible material variable speed conveying device. Background [0002] In the production process of diapers, diapers, sanitary napkins and other products, it is often necessary to disassemble, transfer, align and composite flexible materials, and the speed of the transfer conveyor line and the composite conveyor line is often inconsistent, so it is necessary to transmit the flexible material through a device that can be transmitted at variable speed. The technical solutions provided by the applicant in this case, such as patent No. 201420248893.7, disclose a slitting index variable speed conveyor device, including a frame, a support shaft fixed on the frame, a number of rotary sleeves that can be rotated to each other on the support shaft, a number of first servo motors set on the frame to drive the rotation of the slewing sleeve variable speed rotation, a slewi...

AI Technical Summary

Problems solved by technology

In the above scheme, the center of gravity of the slewing frame is out of the way, so the vibration is relatively large during the speed-changing rotation process, which in turn restricts its maximum rotation speed; there are frequent acceleration and deceleration actions in the speed-changing movement, and slight errors will occur each time under the action of inertia amount, and the accumulation of errors after long-term operation will produce a large amount of misalignment, and when the amount of misalignment is too large, it needs to be stopped for adjustment, so the precision requirements for the servo motor are relatively high
