This utility model relates to the field of material forming technology, specifically to a dry-pressed ceramic plate for metal powder forming. It has a first forming concave-convex portion with multiple draft angles. At least one draft angle of the first forming concave-convex portion is designated as the first draft angle. The angle between the first draft angle and other draft angles is defined as the draft angle, which can be a chamfered or rounded structure. This utility model reduces the bonding area between the dry-pressing mold and the ceramic plate at the draft angle by setting the draft angle to a chamfered or rounded structure, thereby reducing the bonding force and demolding difficulty. It can directly form ceramic plates with small draft angles (e.g., less than 15°) without further machining, reducing costs and improving efficiency. It solves the problem that existing dry-pressed ceramic plates cannot be directly formed with small draft angles and can also serve as a standard mold structure for forming various types of dry-pressed ceramic plates in subsequent designs.

The utility model relates to the technical field of display, in particular to a connecting adhesive tape and a display device. The connecting adhesive tape provided by the utility model is used for connecting a backlight module and a display panel, the connecting adhesive tape comprises foam rubber, an inflation cavity is formed in the foam rubber, an inflation hole communicated with the inflation cavity is further formed in the foam rubber, and a plurality of air outlet holes communicated with the inflation cavity are formed in at least one side of the foam rubber in an array mode. According to the connecting adhesive tape provided by the utility model, when a backlight module and a display panel which are adhered and fixed by the connecting adhesive tape need to be detached, air is inflated into the inflating cavity of the foam adhesive through the inflating hole, so that the air can be discharged through the air outlet hole, and the air discharged from the air outlet hole impacts a bonding surface between the backlight module or the display panel and the foam adhesive; and the bonding area between the backlight module or the display panel and the foam rubber is reduced, so that the backlight module and the display panel are conveniently detached, and the backlight module and the display panel are prevented from being detached and damaged.

The application discloses a belt conveyor for food industrial processing, and relates to the technical field of food industrial processing, which comprises a mounting frame, support frames are fixed on the side edges of the mounting frame, a motor is fixed on the mounting frame, and the output shaft of the motor is fixed with a driving roller. The belt conveyor for food industrial processing realizes stable sliding through the expansion and contraction of the cylinder driving the movable table cooperating with the second sliding block and the second guide rail, can flexibly adjust the conveying distance between the driving roller and the driven roller, accurately adapts to the conveying requirements of different food processing procedures, different material specifications and production line layouts, solves the problems of fixed conveying distance and poor working condition adaptability of the traditional conveyor, and in the conveying distance adjustment process, the conveying belt length between the guide roller and the movable roller can be self-adaptively compensated without manual disassembly and equipment modification, so that the adjustment is convenient and efficient, the universality and application range of the equipment are greatly improved, and the production requirements of multiple types and multiple working conditions of food industrialization are adapted.
