The present invention belongs to the technical field of rice production and transportation, and in particular, is a rice lifting device for rice production and processing. In view of the problem that in the prior art, before the rice is lifted and transported, the rice is generally separated from impurities by a sieve plate, but the multi-stage filtration of the rice cannot be completed, and the dust cannot be removed in time, the filtering effect is poor, and the quality of the rice is affected, the following scheme is proposed, which includes: a mobile frame; a lifting frame, fixedly installed at one end of the top of the mobile frame, a No. 1 motor is fixedly installed on one side of the mobile frame, and two symmetrical vertical grooves are provided on the lifting frame, and the two vertical grooves are slidably connected to the limit frame. The present invention has a simple structure. Before the rice is lifted and transported, the impurities and dust in the rice can be filtered through a multi-stage filtering mechanism, and the generated dust can be collected at the same time, thereby improving the filtering effect, avoiding the situation of affecting the quality of the rice, and being convenient for people to use.

The side wall of the lower die is communicated with a feeding pipe, a preheating structure is arranged in the lower die and comprises a preheating cavity, the preheating cavity is formed in the side wall of the lower die, the inner wall of the preheating cavity is connected with an electric heating plate in a sliding mode, and the surface of the electric heating plate is fixedly connected with a transmission belt. And before raw materials are injected into the lower mold, the lower mold can be preheated firstly, so that the situation that the quality of a cast motor shell is affected due to the fact that the raw materials are cooled too fast in the raw material injection process is prevented, and then the practicability of the casting mold is improved.

The utility model discloses an integrated tea rolling machine set system, relates to the field of tea rolling machines, and solves the problems that a tea pressing device of an existing tea rolling machine is fixedly mounted and is troublesome to clean, cleaning experience is affected, and the quality of tea is affected due to direct contact between the tea pressing device and the tea, the integrated tea rolling machine set system comprises a bottom plate and a rotating plate, the rotating plate is hinged to the top of the bottom plate, an angle adjusting assembly is fixedly installed at the top of the bottom plate and hinged to the rotating plate, a tea rolling assembly is fixedly installed at the top of the rotating plate, and a dismounting assembly is fixedly installed on one side of the tea rolling assembly; and the dismounting and mounting assembly comprises a dismounting and mounting frame and a threaded rod II. According to the tea rolling device, the tea rolling barrel can be quickly detached, so that the tea rolling barrel is more convenient to detach and more convenient to clean, the tea rolling barrel is more sanitary to use due to timely cleaning, the situation that the quality of tea leaves is affected by dirt is reduced, the using effect is better, and the using experience is guaranteed.

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.
