Description

Technical Field

[0001] The utility model relates to the technical field of artificial leather production, and particularly relates to a cooling device for artificial leather production. Background Art

[0002] Artificial leather is divided into two types: PVC and PU. TPU is thermoplastic PU, which is a type of PU leather. When artificial leather is produced, since the leather undergoes thermoplastic molding, at this time, the leather needs to be stretched by rollers to fully contact the air for heat dissipation. During this process, the rotation speed of the rollers needs to be controlled.

[0003] Currently, the cooling of leather is basically natural cooling, and its heat dissipation is affected by the ambient temperature and wind force in the workshop. The heat dissipation is unstable, and the just thermoplastic-molded artificial leather is easily adhered to the dust in the workshop, polluting the leather surface and affecting the appearance quality of the product. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cooling device for artificial leather production, which can quickly dissipate heat from artificial leather, achieve constant-temperature cooling, ensure the stability of artificial leather cooling, and at the same time prevent the just thermoplastic-molded artificial leather from adhering to the dust in the workshop, thus guaranteeing the appearance quality of the product.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A cooling device for artificial leather production includes artificial leather. A concave seat is arranged directly below the artificial leather, and a convex seat is arranged directly above the artificial leather. A plurality of temperature conduction paths penetrate through the concave seat and the convex seat vertically. At the centers of the opposite sides of the concave seat and the convex seat, refrigeration units are respectively arranged in a matching manner. A cooling channel is reserved on the opposite side of the concave seat and the convex seat. A plurality of conveying roller shafts are evenly distributed on the upper and lower sides of the cooling channel. The conveying roller shafts are equidistantly distributed left and right along the opposite side surfaces of the concave seat and the convex seat. At the front and rear ends of the conveying roller shafts, bushings are respectively embedded and rotated. The upper and lower opposite sides of the bushings are respectively embedded and fixed in the inner walls of the concave seat and the convex seat. The above-mentioned artificial leather enters the cooling channel and is in rolling cooperation with the conveying roller shafts. On the outer sides of the concave seat and the convex seat, a plurality of frame seats are symmetrically fixed in a cross shape. On the upper and lower opposite sides of the frame seats, a clamping sleeve and a clamping shaft are respectively fixed. The clamping sleeves are clamped and butted up and down with each other, and it can be directly installed on the artificial leather production line. The refrigeration unit refrigerates and transfers the cold along the temperature conduction paths to the cooling channel to quickly dissipate heat from the artificial leather production section therein, achieve constant-temperature cooling, ensure the stability of artificial leather cooling, and at the same time prevent the just thermoplastic-molded artificial leather from adhering to the dust in the workshop, thus guaranteeing the appearance quality of the product.

[0006] According to the cooling device for artificial leather production, the outer sides of the lower concave seat and the upper convex seat are isolated and encapsulated with a thermal insulation shell, and the outer side of the thermal insulation shell is fitted with a frosted film. It is convenient to prevent slipping during transportation and to provide thermal insulation protection to improve the refrigeration strength, avoid the influence of the external environment temperature, and improve the cooling effect.

[0007] According to the cooling device for artificial leather production, a thermal conductive layer is embedded and fixed on the opposite side of the lower concave seat and the upper convex seat, so as to improve the heat exchange efficiency, perform rapid cooling and temperature reduction, and ensure the travel speed of the production line.

[0008] According to the cooling device for artificial leather production, the outer sides of the conveying rollers are sleeved with rubber sleeves, so as to squeeze and fit the artificial leather, maintain flexible contact, and avoid friction damage to the surface of the artificial leather.

[0009] According to the cooling device for artificial leather production, a sealing cylinder brush is symmetrically arranged on the left side of the top of the cooling groove, and the upper and lower opposite sides of the sealing cylinder brush are respectively engaged and rotated in the inner walls of the lower concave seat and the upper convex seat, and the opposite sides of the sealing cylinder brush are rotated to the left to clean the surfaces of both sides of the artificial leather.

[0010] According to the cooling device for artificial leather production, arc-shaped partitions are symmetrically fixed to the bottom of the front and rear sides of the upper convex seat, and the arc-shaped partitions cover the front and rear sides of the cooling groove downward and slide in contact with the lower concave seat, thereby improving the sealing performance, preventing dust from entering, and improving the temperature.

[0011] The above scheme has the following beneficial effects:

[0012] The utility model can be directly set up on the artificial leather production line, and the refrigeration unit cools the artificial leather and transmits the heat along the temperature conduction path to the cooling groove to quickly dissipate the heat of the artificial leather production section therein, thereby achieving constant temperature cooling and ensuring the stability of artificial leather cooling. At the same time, it prevents the artificial leather that has just been thermoformed from adhering to the dust in the workshop, thereby ensuring the appearance quality of the product.
