Abstract

The invention discloses a leather stretching and leveling device for leather product production and relates to the technical field of leather processing. The leather stretching and leveling device comprises a supporting rack, a leveling table for supporting leather is fixedly mounted on the supporting rack, two clamping mechanisms for clamping leather are symmetrically arranged on two sides of theleveling table, a lead screw I and a lead screw II which are coaxially fixed, opposite in thread rotating direction, are horizontally arranged in the supporting rack, thread bushing blocks in transmission connection to the clamping mechanisms are arranged on the lead screw I and the lead screw II in a threaded connecting sleeving manner, and the lower end of a leaning rod is higher than the bottom surface of a pressure plate. The pressure plate moves downward to compress the leather to the leveling table and the clamping mechanisms are driven by a lifting rack to pull the leather downward, sothat the leather supported by the leveling table is stretched and leveled effectively. A compression roller rolls the leather toward two sides in the process that the pressure plate moves downward, so that the leveling effect of the surface of the leather is improved greatly and the leather leveling efficiency is high.

Description

technical field

[0001] The invention relates to the technical field of leather processing, in particular to a leather stretching and leveling device for leather product production. Background technique

[0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. In the process of human evolution, people found that some plant juices or mineral oils have certain tanning properties on leather. The raw leather is more breathable and antiseptic after being soaked in the juice, so that the board is soft and tear-resistant. , Bending resistance and other physical and chemical properties.

[0003] Before the production of leather products, the leather to be processed needs to be flattened to ensure that the su...

Examples

Embodiment 1

[0026] see Figure 1-6 , a leather stretching and leveling device for leather product production, comprising a support frame 1, a leveling platform 12 for supporting leather is fixedly installed on the support frame 1, and two clamps for clamping leather are arranged symmetrically on both sides of the leveling platform 12 Before performing leather leveling operation, the leather is clamped by the clamping mechanism, wherein the clamping mechanism includes a clamping groove block 17, and a vertical locking stud 18 is threaded on the clamping groove block 17 , the bottom of the clamping groove block 17 is fixed with a sleeve 22, and the sliding column 21 fixed with the threaded sleeve block 13 is slidably installed in the sleeve 22.

[0027] The two sides of the leather are clamped into the clamping groove block 17, and the locking stud 18 is screwed down until the leather is pressed and fixed in the clamping groove block 17. Further, there is a The compression slot 19 vertical...

Embodiment 2

[0034] In order to further improve the leveling effect of the leather surface, on the basis of Embodiment 1, in addition, the bottom of the pressing plate 2 is horizontally provided with an accommodation groove 30, and a turret 28 is hinged in the accommodation groove 30, and a pressure roller 25 is rotatably arranged on the turret 28. An extension plate 33 is fixed on the side wall of the pressing plate 2 , and a return spring 24 is fixedly connected between the extension plate 33 and the turret 28 .

[0035] When the pressure plate 2 moves down, the pressure roller 25 touches the leather, and when the pressure plate 2 continues to press down, the turret 28 swings and deflects, and the pressure roller 25 rolls the leather to both sides of the leather, which promotes the stretching of the leather and To further smooth the leather, and the elastic action of the reset spring 24 provided on the turret 28 downward ensures that the pressure roller 25 has sufficient pressing force on...
