The utility model discloses a cooling device with self -cleaning structure for aluminium profile production relates to aluminium profile production technical field. The utility model discloses a bottom plate is provided with self -cleaning mechanism and cooling mechanism on the bottom plate, and the top fixedly connected with workstation of bottom plate, the round tank is opened in the workstation, and the inner wall fixedly connected with the baffle of workstation, the top rotationally connected with the pivot of workstation, and the bottom extension of pivot reaches in the round tank, and the outer wall fixedly connected with the turntable of pivot, and the outer wall fixedly connected with the limit box of turntable, and the rear side inner wall fixedly connected with spring telescopic link of limit box. The utility model discloses through setting self -cleaning mechanism, has solved the current aluminium profile production cooling device when using, because of not carrying out in time cleaning, after long -term use, the scale, oil dirt, dust and other impurities accumulated on the baffle, will be attached on it, thereby influence aluminium profile finished product quality's problem.

The utility model relates to the technical field of film blowing machine equipment, and discloses a traction structure of a film blowing machine, which comprises an outer shell and two connecting shells, the bottom wall of the front side of the outer shell is fixedly connected with a fixed frame, the left side of the inner wall of the fixed frame is fixedly connected with a servo motor, the output end of the servo motor is fixedly connected with a traction roller, and the traction roller is fixedly connected with the connecting shells. And the right end of the traction roller is rotationally connected to the right side of the inner wall of the fixing frame, a swing air cylinder is fixedly connected to the left side of the inner wall of the shell, and the right end of the swing air cylinder is fixedly connected to the left side of the connecting shell on the left side. According to the utility model, the tension of the thin film can be preliminarily adjusted through the expansion and contraction of the rotary adjusting roller, and then the rotary rod can swing by taking the middle part of the inner wall of the shell as an axis under the driving of the swing cylinder to finish the secondary adjustment of the tension during thin film traction, so that the condition that the quality of the thin film is influenced is reduced, and the traction effect is improved.

The utility model relates to the technical field of printing paper carding equipment, and discloses paper carding equipment for a printing machine, which comprises a printing machine body, a conveying table is fixedly mounted on one side, close to the lower end, of the printing machine body, and square carding blocks which are symmetrical in pairs are fixedly mounted at the upper end of the end of one side of the conveying table. The center of one side of each square carding block is rotationally provided with a double-screw rod, the outer side walls of the double-screw rods are rotationally provided with threaded sleeves in a pairwise symmetrical mode, and the lower ends of the threaded sleeves are fixedly provided with limiting clamping plates. The width between the two limiting clamping plates is flexibly adjusted so as to adapt to feeding of paper of different sizes, the side edges of the paper are limited through a progress channel formed by the limiting clamping plates, and meanwhile, the two pressing rotating rollers which are symmetrical to each other and can be adjusted in a rolling mode are arranged, so that warpage generated by the paper can be pressed when the paper is carded and moved.
