Hard leather fracturing instrument

Abstract

The invention discloses a hard leather fracturing instrument, which comprises a support part, a controller, a control panel, a pressing device and a bending device. The pressing device comprises a second electric telescopic rod, a connecting plate and a pressing fixing portion; the bending device comprises a bending mold and a backfin part; the bending mold comprises a cylindrical inner mold, a cylindrical outer mold which is installed on the outer side of the inner mold and sleeved layer by layer, a locking component which is mounted at the bottom of the inner mold and the outer mold and a third electric telescopic rod which is mounted at the bottom of the cylindrical inner mold; the backfin part comprises a stepping motor, a gear, a sliding block, a first electric telescopic rod, a roller, a guide rail, and an annular rack; and the control panel, the stepping motor, the first electric telescopic rod, the second electric telescopic rod and the third electric telescopic rod are all connected with a controller through guide wires. The hard leather fracturing instrument in the invention is controlled through the controller; clamping and bending of the hard leather sample is automatically realized; the automatic degree is high; the bending mold adopts a layer-by-layer sleeved design; convenience is brought for storage; and the occupied space is small.

Description

technical field [0001] The invention relates to the field of leather detection, in particular to a hard leather breaker. Background technique [0002] After the leather is produced, a variety of physical and chemical tests are required to ensure the quality of the leather. Among them, the crack resistance of the leather is an important indicator that often needs to be tested. There may be problems such as broken leather products and shortened service life. Currently, the leather fracture testers on the market are simple in structure and low in automation. Most of them are manually driven for fracture testing. Not only is the operation complicated and laborious, but it is also difficult to The leather with larger thickness and higher hardness is tested. Moreover, when the existing leather breaker is used, problems such as loose clamping and loosening of the compression during bending are likely to occur due to improper operation, which will affect the test results.

[0002] After the leather is produced, a variety of physical and chemical tests are required to ensure the quality of the leather. Among them, the crack resistance of the leather is an important indicator that often needs to be tested. There may be problems such as broken leather products and shortened service life. Currently, the leather fracture testers on the market are simple in structure and low in automation. Most of them are manually driven for fracture testing. Not only is the operation complicated and laborious, but it is also difficult to The leather with larger thickness and higher hardness is tested. Moreover, when the existing leather breaker is used, problems such as loose clamping and loosening of the compression during bending are likely to occur due to improper operation, which will affect the test results. In addition, the current Some leather fracture instruments need to use multiple test columns of different sizes. These test columns will take up a lot of space when not in use, and are not easy to store, which brings inconvenience to use
