[0026] The following combines the drawings and embodiments to further describe the detailed implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0027] "Above", "below", and "bottom" are referenced based on the normal use state of the processing and production system of polyester fibers, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0028] In addition, terms such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present creation of the utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0029] As Figures 1 - 2 shown, the processing and production system of polyester fibers of the present utility model includes a spinning unit 1 and a drawing unit 2, and also includes a crimping unit 3, a cutting unit 4, and a packing unit 5. Among them, the spinning unit 1 includes a spinning machine 11, a base 6, an oil pipe (not shown), a circulation main pipe 111, and a cooling pipe 14. The spinning machine 11 is provided with multiple groups of spinning ports (not shown) hanging vertically downward; the base 6 is provided with cooling rollers 10 and end traction rollers 12 that correspond to the spinning ports one by one and are located below them, and is also provided with a recovery tank 13 at the bottom with a notch facing the cooling roller 10; the oil pipe is provided with an oil injection port facing the cooling roller 10 and located above it, and is connected to the oil source 100. The oil from the oil source 100 is transported to each cooling roller through the oil pipe by a delivery pump 16. The oil pipe is arranged on the back of the base 6; the circulation main pipe 111 is sequentially connected to the recovery tank 13 and the oil source 100, and is also provided with a main filter 101; the cooling pipe 14 is used to cool the oil in the recovery tank 13; the cooling roller 10 is a driving roller.

[0030] The cooling roller 10 corresponding to the spinning nozzle not only helps cool the fiber filaments, but the actively rotating cooling roller 10 increases the contact area with the fiber filaments, making the fiber filaments more fully oiled; the oil liquid resources can be more fully utilized through the recovery tank 13 and the main circulation pipeline 111.

[0031] Optimize the connection structure between the base 6 and the cooling roller 10 to prevent the oil liquid from splashing everywhere, so as to avoid wasting the oil liquid and reducing the contact amount of the oil liquid with the fiber filaments. The base 6 is provided with a recessed part (not shown in the drawing), that is, the recessed part protrudes from the back surface of the base 6. The cooling roller 10 is in concave-convex fit with the recessed part, and the roller surface of the cooling roller 10 protrudes from the opening of the recessed part, so that the roller surface of the cooling roller 10 is tangent to the fiber filaments. The recessed part is provided with a long and narrow oil inlet extending along the length of the cooling roller 10.

[0032] The cooling roller 10 is provided with at least two unit rollers in a group along the plumb direction. A pressure roller 15 is arranged between adjacent unit rollers in the same group. A wire passing channel is arranged between the cooling roller 10 and the pressure roller 15, and the wire passing channel is located on the same side of the cooling roller 10. Further, the unit rollers in the same group rotate synchronously, which not only simplifies the driving equipment, but also ensures the same traction force to prevent the fiber filaments from breaking. Among them, the setting of the pressure roller 15 helps the fiber filaments to cling to the cooling roller 10, improving the oiling efficiency and rapid cooling. The wire passing channel is located on the same side of the cooling roller, and the wire can be routed on the surface of the base 6, and the oiling situation of the fiber filaments can be directly observed, and the oil liquid flows along the surface of the base 6 to accelerate cooling and prevent splashing.

[0033] The main filter 101 is detachable, which is convenient for cleaning and replacing parts.

[0034] Further, the bottom of the recovery tank 13 is inclined to prevent the fiber fluff falling on the surface of the recovery tank from blocking the circulation of the recovered oil liquid.

[0035] In order to prevent the oil liquid of the oil liquid source 100 from flowing back to the recovery tank 13, the surface of the recovery tank 13 is higher than the oil surface of the oil liquid source 100, and the recovered oil liquid can flow smoothly to the oil liquid source 100. Preferably, both the main circulation pipeline 111 and the bypass auxiliary pipeline 122 are communicated with the oil inlet of the oil liquid source 100, and the distance from the oil inlet to the bottom of the oil liquid source is greater than the distance from the oil outlet of the oil liquid source 100 to the bottom of the oil liquid source. Further, the pipelines of the bypass auxiliary pipeline 122 and the main circulation pipeline 111 communicating with the oil liquid source 100 are filtrate outlet pipes (not marked), and the filtrate outlet pipes are provided with circulation pumps (not marked).

[0036] The cooling pipe 14 is provided with a branched outlet pipe 202, and the branched outlet pipe 202 is communicated with the liquid inlet of the water bath heater 20 in the stretching unit 2. Part of the waste heat of the cooling oil liquid is transmitted to the next process, and the heat is further effectively and fully utilized to achieve the effect of energy saving.

[0037] Such as Figure 2As shown, in some preferred embodiments, a bypass auxiliary pipeline 122 is further provided to ensure the continuity of production. The bypass auxiliary pipeline 122 is provided with an auxiliary filter 102, and a filter element (not labeled) is arranged inside the auxiliary filter 102. The filter element divides the inner cavity of the auxiliary filter into a liquid inlet cavity (not labeled) and a liquid outlet cavity (not labeled). The two ends of the bypass auxiliary pipeline 122 are respectively communicated with the recovery tank 13 and the oil source 100. That is, the bypass auxiliary pipeline 122 is connected in parallel with the main circulation pipeline 111, and the recycling of the recovered oil can be realized by switching the pipelines. The pipeline connecting the bypass auxiliary pipeline 122 or the main circulation pipeline 111 to the recovery tank 13 is a filtrate inlet pipe. The oil pipe is provided with a flushing branch pipe 103 communicated with the liquid inlet cavity, and the auxiliary filter 102 is provided with a flushing outlet pipe 104. The flushing outlet pipe 104 is communicated with the filtrate inlet pipe. It realizes the non-disassembly cleaning of the auxiliary filter and timely discharges the filter residue in the auxiliary filter.

[0038] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
