Technical Field

the invention relates to the field of tire production equipment.

In particular to a forming machine.

Background

The traditional forming machine comprises a machine frame, wherein a forming drum and a pressing roller are arranged on the machine frame, when the forming machine is used, an operator firstly places a sheet on the forming drum, the forming drum rotates to roll the sheet on the forming drum, and when the sheet passes through the pressing roller, the pressing roller and the forming drum press the sheet to finally manufacture a tire blank.

The sheet is not flat after placement and is prone to wrinkling or other deformation. After the sheet with wrinkles or other deformations is pressed by the pressure roller and the building drum, air bubbles are formed on the inner side of the sheet, and bulges are formed on the outer side of the sheet. The quality of the tire blank is affected, and at the moment, the tire blank needs to be reworked or scrapped, so that economic loss is caused.

To solve the above problem, the current method is to manually flatten the sheet on the building drum by an operator to reduce the occurrence of wrinkles or other deformations. However, the forming drum is a moving part, and if the forming drum is operated while rolling up the sheet and smoothing the sheet by an operator, the operator is slightly hurt carelessly, so that in actual production, the rotation of the forming drum needs to be stopped first, and the forming drum is started after the operator levels the sheet on the forming drum, so that the production efficiency is low.
