Description

Technical Field

[0001] This utility model relates to the field of leather technology, and in particular to an automated device for stretching, matching and grading steering wheel leather pieces. Background Technology

[0002] Genuine leather steering wheel covers require high elongation rates for the leather pieces (e.g., specific range and direction of elongation). When the elongation of the leather pieces exceeds the required range, issues such as failure to fit the wheel, difficulty in fitting, and misalignment at the joint can occur. Furthermore, cowhide is a natural product, and the direction and magnitude of elongation vary between different types of cowhide and even between different parts of the same cowhide. To address these issues, the cut leather pieces need to be tested and screened. Pieces meeting the elongation range are shipped as qualified products, while those exceeding the range are discarded. Previously, machines were used to screen leather pieces by stretching them and providing corresponding tensile force values. However, since the measured values ​​are in Newtons, they do not directly reflect whether the leather pieces truly meet the elongation requirements. Therefore, the existing stretching and matching machine needs to be modified to automatically classify and categorize steering wheel leather pieces according to set values ​​after stretching inspection.

A movable table 11 is slidably connected to the stretching guide rail 6. The movable table 11 is sequentially connected to the ball screw 5 and the servo motor 3, with the ball screw 5 and the servo motor 3 connected via a coupling 4. The movable table 11 is connected to both the movable lower clamp and the movable upper clamp assembly.

[0023] Operating instructions:

[0024] 1. Click the Auto button on the main screen of Touchscreen 1 to enter the automatic working state and prepare for work.

[0025] 2. Manually place the leather, press the start button 14 with both hands, fix the cylinder 7, move the cylinder, fix the upper clamp 9, fix the lower clamp 10, move the upper clamp and move the lower clamp to clamp the leather piece, the servo motor 3 starts to rotate, move the table 11, move the upper clamp assembly and move the lower clamp together to stretch the leather piece.
