The heating layer has a heating position located below the upper shell and an outward food taking device located on a lower shell; in the heating process, the heating layer and the upper shell are sealed, after heating is completed, the heating layer can be rotated out to conveniently take food, after the food is taken, the heating layer then returns to the heating position, and the heating layer and the upper shell are sealed. By means of the structure, on the premise of guaranteeing sealing, the heating layer is rotated in and rotated out, and a user conveniently takes the food.

The invention relates to a athwart braider winding-proof blocking device that includes blocking board and installation board. The upper part of blocking board is bent to certain pitch to overreach the bottom location of great gross, and adhesive tape, which is contacted to batching strap, or close to batching belt and the clearance below the thickness of fabric, is set near great gross. Thus, the adhesive tape could effectively avoid fabric rotating with batching belt and ensure normal falling of the fabric.

The invention discloses a positioning device, and discloses a motor with the positioning device. One of the positioning devices includes a stator and a rotor casing. It is characterized in that the rotor casing is provided with a positioning piece, and the positioning piece includes an elastic part connected with the rotor casing and a positioning part connected with the elastic part. A protrusion is arranged between the positioning part and the stator. The body and the concave part for accommodating the convex body, the convex body and the concave part are positioned in cooperation, and the rotation of the rotor shell drives the convex body and the concave part away from each other. A positioning device of the present invention can position the rotor casing when the motor stops rotating.

The invention discloses a thermosetting saturated carboxyl-terminated polyester resin and a preparation method thereof. The raw materials include dibasic or polybasic acid monomers, dibasic or polyvalent alcohol monomers, catalysts, heat stabilizers and acidifiers, and the crystallinity can be as high as 47.85%, good crystallinity, it uses dibasic or polyalcohol, dibasic or polybasic acid as raw material, (1) rigid groups such as phenyl and cyclic compounds are introduced into the main chain, which hinders the rotation of single bonds and reduces the The flexibility of the main chain of the polyester resin molecule increases the Tg of the resin and improves the storage stability of the powder coating produced by it; (2) The monomer with a symmetrical structure improves the regularity of the molecular chain, makes the resin partially crystallize, and forms a crystalline structure It is beneficial to reduce the melt viscosity of the powder coating system configured with the resin and improve the reactivity of the resin and the curing agent. The polyester resin has undergone a fundamental change in the molecular structure, and the synthesized thermosetting saturated carboxyl-terminated polyester resin has low viscosity, high Tg properties.

The invention relates to an ADA'DA type fully fused ring organic small molecule and its preparation method and application, and belongs to the technical fields of organic functional materials and photovoltaic cells. The technical problem of poor stability of photovoltaic small molecule receptor materials in the existing technology is solved. The organic small molecule provided by the invention adopts a completely condensed ADA'DA configuration molecular skeleton, in which A' is the central core, A is the terminal group, A' and A are electron-pulling units, and D is the connecting unit. Electronic unit. Experimental results show that this ADA'DA type fully fused ring organic small molecule has high chemical stability and photostability, good skeleton planarity, and excellent charge transport properties. By regulating the central core, connecting units and end groups, respectively The ability to push and pull electrons can achieve precise control of HOMO / LUMO energy levels, thereby achieving control of the absorption spectrum. It can be used as an electron acceptor in organic solar cells to achieve excellent device performance.

The invention provides a spindle unit which suppresses difficult rotation of a spindle because of machining debris. A sealing portion (68) on a lower end of a cover portion (67) of a spindle cover (66) has an upper side surface (68a) and a lower side surface (68b) that are inclined toward an outer circumferential surface (77a) of the spindle (44). A larger-diameter disk and the outer circumferential surface (77a) of the spindle (44) define therebetween a second gap (T2) that is narrower than a first gap (T1) defined between the spindle (44) and the cover portion (67). The second gap is effective to prevent a processing waste liquid from entering between the spindle (44) and the spindle cover (66) to prevent a solid waste contained in the processing waste liquid from sticking to the spindle. The spindle (44) is thus prevented from becoming less liable to rotate smoothly due to solid waste deposits.
