Description

Technical Field

[0001] This utility model relates to the field of leather embossing technology, and in particular to a cooling rack for leather embossing. Background Technology

[0002] On a leather embossing production line, the surface of the leather needs to be heated and softened before embossing to ensure a clear embossing effect. After embossing, the leather needs to be cooled. The common cooling method is natural cooling, which involves wrapping the leather around a cooling roller to allow it to cool naturally. However, this cooling method has two problems: firstly, natural cooling is ineffective; secondly, the leather shrinks during cooling, affecting the embossing effect. Existing cooling racks cannot adjust the tension of the leather, making it difficult to solve the problem of shrinkage during air cooling affecting the embossing effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a cooling rack for leather embossing, which can solve the problems of poor cooling effect of general leather embossing cooling racks and the lack of tension adjustment structure, which causes the leather to shrink during cooling and affect the embossing effect.

[0006] The leather cooling roller has two sets, namely an upper leather cooling roller set and a lower leather cooling roller set, and each set has two leather cooling roller units; the two leather cooling roller units of the upper leather cooling roller set are provided with bearings at their ends and are mounted on the top of the side frame with bearing seats; the two leather cooling roller units of the lower leather cooling roller set are provided with bearings at their ends and are mounted on the support beam with bearing seats.

[0007] The leather tension adjustment frame has a pair of support beams mounted on two side frames respectively; the leather tension adjustment frame includes an adjustment frame, a bearing seat, a tension adjustment roller, and an adjustment screw; the adjustment frame is rectangular and arranged in a vertical plane; a guide rail is arranged along the horizontal direction on the upper surface of the bottom end of the adjustment frame, and a slider is arranged on the guide rail; a threaded hole is arranged along the horizontal direction at one end of the adjustment frame; the bearing seat is mounted on the slider; both ends of the tension adjustment roller are connected to the bearing seat through slewing bearings; the adjustment screw mates with the threaded hole at one end of the adjustment frame, and one end of the adjustment screw is connected to the bearing seat through a thrust bearing; by rotating the adjustment screw, the bearing seat is driven to reciprocate along the extension direction of the guide rail, thereby realizing the movement of the tension adjustment roller in the horizontal direction.

[0008] Furthermore, a leather feeding reversing roller is provided on the base of the support frame; a leather discharging reversing roller is provided on the side of the support frame near the top.

[0009] Furthermore, a pair of cooling air ducts are provided on the support beam between the two leather cooling roller units, with one end of the cooling air duct closed and the other end connected to an air source; the cooling air ducts are provided with several air blowing holes, and the air blowing holes of the two cooling air ducts blow air towards the leather cooling roller units on both sides respectively.

[0010] The advantages of this utility model are:

[0011] 1) In this utility model, by setting a leather tension adjustment frame on the support frame, the tension adjustment roller moves horizontally under the drive of the adjustment screw, thereby maintaining sufficient tension in the leather before cooling. This improves the heat dissipation effect of the leather and avoids the problem of rapid shrinkage during cooling, which affects the embossing effect. In addition, a cooling air duct is set on the support beam to blow air to cool the leather cooling roller unit, which improves the cooling effect of the leather. Attached Figure Description
