When the connecting plate rotates to a specified angle, a corresponding flattening roller contacts the coated surface of the coated roll, causing the flattening roller to compress the coated roll and generate pressure, thus adjusting the coating thickness according to different processing requirements, greatly improving production flexibility and product quality.

The application relates to the technical field of temperature-sensitive control, in particular to an automatic reset type temperature-sensitive control device, which comprises a device main body, rotating boxes are fixedly connected to the two sides of the device main body, an alternating heat conduction mechanism is arranged in the rotating boxes, the alternating heat conduction mechanism comprises heat insulation plates which are slidingly connected in the rotating boxes, left plates and right plates are fixedly connected to the two sides of the heat insulation plates, left heat conduction fins are slidingly connected to the end portions of the left plates, when the electrical equipment is damaged to cause abnormal temperature rise, the bimetallic strip is bent greatly when sensing the continuous high temperature, at the moment, the pressure rod drives the bimetallic strip to move downwards and is separated from the right heat conduction fin, the continuous transmission of the heat source to the bimetallic strip is cut off, plastic deformation of the bimetallic strip beyond the elastic bending limit is avoided, the bimetallic strip can be normally reset when the temperature falls back, and the long-term use performance of the bimetallic strip is ensured.

The invention discloses a film-forming lubricating wear-resistant lead screw working fluid and a preparation method thereof. The processing liquid is prepared from the following components in parts by weight: 12 to 28 parts of surface modified nano nickel ferrite, 2.5 to 8.5 parts of ferroferric oxide, 6 to 15 parts of a compound adhesive, 8 to 22 parts of a compound dispersant, 0.8 to 3.2 parts of a compound antioxidant and 50 to 99 parts of base oil. The preparation method comprises the steps of step-by-step modification, ultrasonic dispersion and high-shear homogenization. Through a magnetic synergistic lubrication system and a rapid film forming technology, the technical problems of insufficient lubrication performance, poor wear resistance and difficult film forming of the traditional screw rod working fluid are solved. Compared with the traditional cutting fluid, the optimal embodiment of the invention realizes the remarkable effects that the friction coefficient is reduced by 57.1%, the tool wear is reduced by 42.5%, the surface roughness is improved by 60.4%, and the dispersion stability exceeds 30 days.

The invention relates to the technical field of temperature-sensitive control, in particular to an automatic reset type temperature-sensitive control device which comprises an equipment body, a bimetallic strip is installed in the equipment body, alternating boxes are fixedly connected to the two sides of the equipment body, and alternating heat conduction mechanisms are arranged in the alternating boxes. The alternating heat conduction mechanism comprises a heat insulation plate slidably connected to the interior of the alternating box, the two sides of the heat insulation plate are fixedly connected with a left plate and a right plate correspondingly, and the end of the left plate is slidably connected with a left heat conduction piece. When the bimetallic strip is greatly bent after sensing continuous high temperature, the pressing rod can drive the bimetallic strip to move downwards and be separated from the right heat conducting strip, continuous transmission of a heat source to the bimetallic strip is cut off, the bimetallic strip is prevented from exceeding the elastic bending limit and generating plastic deformation, it is ensured that the bimetallic strip can be normally reset when the temperature falls back, and the long-term use performance of the bimetallic strip is guaranteed.

The earphone adjusting structure comprises an adjusting box body and an adjusting part, the inside of the adjusting box body is provided with a first sliding cavity and a second sliding cavity, the adjusting part is provided with a first adjusting rod, a second adjusting rod and an intermediate connecting rod, the first adjusting rod is slidingly arranged in the first sliding cavity, and the second adjusting rod is slidingly arranged in the second sliding cavity; the inner wall of the first sliding cavity and the inner wall of the second sliding cavity are both provided with an anti-skid layer; the inner wall of the first sliding cavity and the inner wall of the second sliding cavity are both provided with the anti-skid layer, so that when sweat and grease enter the first sliding cavity or the second sliding cavity, the grease and the sweat cannot be attached to the anti-skid layer of the first sliding cavity and the anti-skid layer of the second sliding cavity, the adjusting failure caused by excessive sliding is avoided, and the stability of the earphone adjusting structure is ensured.
