Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production and processing of plastic woven bags, in particular to a composite cooling device for laminating a whole roll of plastic woven bags. Background Art
[0002] Plastic woven bags usually need to be coated in the whole roll during the production process. The adhesiveness of the coating material in the molten state is used to carry out plastic coating, paper plastic coating, or coating with printed OPP and CPP films. The whole roll coating process usually uses a coating machine, which is also called an extrusion laminating machine, a casting machine, an extrusion casting machine, a casting laminating machine, a coating machine, a plastic coating machine, and a coating laminating machine. It is a kind of extrusion molding machine.
[0003] Plastic woven bags need to be cooled when the whole roll is coated. At present, many of them are cooled by air cooling. Air cooling actually blows cold air directly on the surface of the woven bag. This method cannot form sufficient air convection on the surface of the woven bag, resulting in poor cooling effect and uneven cooling, which can easily cause cracks in the composite coating and reduce product yield. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a composite cooling device for laminating a whole roll of plastic woven bags.
[0005] The utility model is realized through the following technical scheme: a composite cooling device for whole roll lamination of plastic woven bags, comprising a device frame and a cooling roller installed on the device frame, a flow guide shell is arranged above the cooling roller, and an air inlet fan and an air outlet fan are respectively installed at two ports of the flow guide shell.
[0006] The air inlet of the air inlet fan is provided with an air filter.
[0007] A surface cooler is arranged below the air inlet fan.
[0008] Threaded rods and sliding rods are rotatably installed on both sides of the guide shell, and nut sleeves are installed on the threaded rods, and the ends of the threaded rods are connected to the output shaft of the driving motor. The nut sleeves are fixed on one side of the guide shell, and a sliding sleeve is slidably installed on the sliding rods, and the sliding sleeve is fixed on the other side of the guide shell.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] 1. The utility model has a guide shell arranged above the cooling roller, and an air flow channel is formed in the guide shell. Through the air inlet and outlet fans, sufficient air flow is formed on the surface of the woven bag to achieve high air convection, improve the cooling effect, cool evenly, and improve the product yield;
[0011] 2. The utility model has threaded rods rotatably installed and sliding rods fixed on both sides of the guide shell, and drives the guide shell to rise and fall through the driving motor, nut sleeve and sliding sleeve, thereby adjusting the height of the guide shell, that is, adjusting the distance between the guide shell and the woven bag on the cooling roller, and realizing the adjustment of wind speed under the same air volume, thereby realizing the adjustment of cooling efficiency and meeting more cooling requirements of the woven bag.
