Description

Technical Field

[0001] The utility model relates to the technical field of flame laminating machines, in particular to a fast-cooling flame laminating machine for laminating leather. Background Art

[0002] The flame laminating machine for composite leather combines two or more different types of materials through high-temperature, high-pressure flames, creating a new composite material with unique physical and chemical properties. This composite material typically exhibits enhanced strength, stiffness, wear resistance, and tensile strength, while also improving certain properties of the original material, such as toughness and softness.

[0003] However, in the current existing technology, after the composite leather is heated and compressed, it is cooled in the mold to solidify and form. Before the composite material is completely cooled, it will maintain close contact and adhesion with the winding roller for a period of time. In addition, when the winding roller is cooled, the rapid cooling is transmitted to the composite material, causing the surface of the composite leather to shrink rapidly. The outside of the winding roller is fixed, resulting in the composite material adhering to the outer wall of the winding roller when cooling, and causing pulling and tearing when shrinking, affecting the quality of the composite material. Utility Model Content

The inner walls of the multiple through slots are all inclined structures and the angles correspond to the protrusions.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the embodiments of the present invention. Example

[0022] See also Figure 1-4 The utility model provides a technical solution: a flame laminating machine for rapid cooling of composite leather, comprising a conveyor roller 1, wherein a cooling assembly for cooling the composite leather is provided inside the conveyor roller 1, wherein the cooling assembly comprises a plurality of through grooves 2 provided on the outer wall of the conveyor roller 1, so that the conveyor roller 1 communicates with the interior, an inner tube 3 is provided inside the conveyor roller 1 for layering the winding roller, a cooling chamber 301 is provided inside the inner tube 3 for storing cold air and conducting the cooling to the outer tube to cool the composite leather after heating and compression, a plurality of cavities 4 are provided on the outer wall of the inner tube 3 for positioning and positioning the protrusion 5 To provide shrinkage space, a plurality of the cavities 4 are each provided with a spring 401 and a protrusion 5. The spring 401 is used to support the protrusion 5 and push it to be embedded in the through groove 2. The protrusion 5 can fill the through groove 2. When the leather cools and shrinks, the protrusion 5 adheres to the protrusion 5 and cooperates with the inclination angle of the inner wall of the through groove 2, which will drive the protrusion 5 to move in the through groove 2, thereby providing space for the leather to shrink and avoiding pulling during shrinkage due to adhesion (and when the protrusion 5 is pulled to move in the through groove 2, it is misaligned with the through groove 2, so that the through groove 2 is connected to the inside of the conveyor roller 1, so that the cold air inside the conveyor roller 1 can flow out from the gap and be transported to the leather, thereby improving the cooling effect).

[0023] Please refer to the attached Figure 4-5As shown, the inner wall of the cooling chamber 301 is provided with a plurality of conical grooves 6, which can transport the cold air in the cooling chamber 301 to the mesh plate of the inner tube 3 and transmit it from the holes of the mesh plate to the internal space of the conveyor roller 1, so as to cool the conveyor roller 1 and the leather. The inner walls of the plurality of conical grooves 6 are provided with a plurality of baffles 7, which are closed by the force of the spring shaft in the normal state to seal the conical grooves 6. (In the early stage of cooling the leather, after the cold air enters the cooling chamber 301, the pressure of the cold air can open the conical grooves 6 to allow a small amount of cold air to flow into the interior of the conveyor roller 1 to cool the leather.) Leather cooling, since a small amount of cold air acts on the conveying roller 1, the temperature will not drop rapidly, thereby achieving pre-cooling of the leather). One end of each of the multiple baffles 7 is provided with an electromagnet 701. After pre-cooling, the PLC controller controls the repulsion between the electromagnets 701 to push the baffle 7 toward the inner wall of the conical groove 6 to rotate and shrink, so that the conical groove 6 is connected, so that the cold air can completely flow into the conveying roller 1. Pre-cooling can reduce the temperature difference between the leather and the winding roller during cooling, reduce the shrinkage of the leather surface, protect the leather, and avoid the chance of pulling and tearing.

[0024] In this embodiment, all electrical components are controlled by conventional controllers.

[0025] For example, please refer to Figure 1-5The inner tube 3 is located in the conveying roller 1 and is rotatably connected to the inner wall of the conveying roller 1 through a bearing. The multiple cavities 4 on the outer wall of the inner tube 3 correspond to the through slots 2 on the conveying roller 1. The outer wall of the inner tube 3 is sleeved with a mesh plate. The cavity 4 is connected to the through slot 2. One end of the convex block 5 is located in the cavity 4 and is slidably connected to the inner wall of the cavity 4 through a slide rail. The end of the convex block 5 away from the cavity 4 is a conical structure. The spring 401 is located in the cavity 4, and both ends are welded to the inner wall of the cavity 4 and the convex block 5 respectively. The protrusion 5 is connected to the through groove 2, and the protrusion 5 can be pushed out of the cavity 4 and extended into the through groove 2 by the spring 401, and is flush with the edge of the through groove 2. The inner walls of the multiple through grooves 2 are all inclined structures and the angles correspond to the protrusion 5. The two ends of the multiple conical grooves 6 are respectively connected to the mesh plates of the cooling bin 301 and the outer wall of the inner tube 3. The baffle 7 array is distributed on both sides of the inner wall of the conical groove 6 and is rotatably connected to the inner wall of the conical groove 6 through a spring shaft. The electromagnet 701 is connected to the end of the baffle 7 away from the conical groove 6 by a bolt. During use, the heated and compressed composite leather is moved to the conveyor roller 1 through the transmission mechanism for rotation and collection. At the same time, the cold air is transported to the cooling chamber 301 in the inner tube 3 through the pump body and the conveying pipe. A small amount of cold air will flow into the conical groove 6 and push the baffle 7 open and flow into the interior of the conveyor roller 1 through the mesh plate on the outer wall of the inner tube 3 to achieve cooling, thereby pre-cooling the leather outside the conveyor roller 1. After pre-cooling, the PLC controller controls the repulsion between the electromagnets 701 to push the baffle 7 to rotate and shrink, and at the same time, the cold air is completely circulated to the interior of the conveyor roller 1 to quickly cool the leather. During cooling, the leather will shrink due to cooling. At the same time, due to the adhesion with the protruding block 5 in the through groove 2, the block 5 floats slightly in the through groove 2 to provide space for the leather to shrink, and the block 5 is misaligned with the through groove 2 to produce a gap. The cold air in the conveyor roller 1 flows out through the gap and is transmitted to the leather to improve the cooling effect.

[0026] The working process of the utility model is as follows: when in use, the heated and compressed composite leather is moved to the conveying roller 1 through the transmission mechanism for rotation and collection, and at the same time, the cold air is conveyed to the cooling chamber 301 in the inner tube 3 through the pump body and the conveying pipe. A small amount of cold air will flow into the conical groove 6 and push the baffle 7 open to flow into the interior of the conveying roller 1 through the mesh plate on the outer wall of the inner tube 3 to achieve cooling, thereby pre-cooling the leather outside the conveying roller 1. After pre-cooling, the PLC controller controls the repulsion between the electromagnets 701 to push the baffle 7 to rotate and shrink, and at the same time, the cold air is completely circulated to the interior of the conveying roller 1 to quickly cool the leather. During cooling, the leather will shrink due to cooling, and at the same time, due to the adhesion with the protruding block 5 in the through groove 2, the block 5 is driven to float slightly in the through groove 2 to provide space for the leather to shrink, and the block 5 is misaligned with the through groove 2 to produce a gap. The cold air in the conveying roller 1 flows out through the gap and is transmitted to the leather to improve the cooling effect. The utility model realizes pre-cooling treatment, reduces the temperature difference between the leather and the winding roller, and provides shrinkage space when the leather is cooled by arranging shrinkable protrusions outside the winding roller, thereby avoiding pulling and tearing.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
