The invention relates to a bearing plate stack structure and a bearing plate. The bearing plate stack structure includes a plurality of bearing plates mutually stacked and an upper cover configured on the top layer of bearing plate. Each bearing plate has a plurality of bearing areas, a plurality of depressions, a bearing body and a first interval part. In each bearing plate, the bearing areas and the depressions are configured with the bearing body and all the depressions are adjacent to at least one bearing areas and are provided with the bottom parts and through holes positioned at the bottom parts. In each bearing plate, the first interval part is configured around a bearing body, and the first interval part and the bottom part of each depression are positioned on the same side of thebearing body. In any two adjacent bearing plates, each through hole of the upper layer is communicated with one of the through hole of the lower layer, and the first interval part of the upper layer is closely connected with the lower bearing body. The upper cover comprises a cover body which covers the top layer of bearing body and a second internal part which is configured around the cover bodyand closely connected with the top layer of bearing body. Therefore, foreign particle residuals can not easily occur on each bearing area of the bearing plate with stack structure and vacuum packaging.

The invention discloses a photosensitive agent containing a diazo group, a photoresist composition for a diazo positive LCD and a preparation method thereof. The curcumin sensitizer containing diazo group of the present invention is a compound with structural formula as shown in formula I: the photoresist composition of the present invention includes film-forming resin, the curcumin sensitizer containing diazo group and organic solvents. The molecular weight of the diazonaphthoquinone sensitizer of the present invention is 394, compared with the existing diazonaphthoquinone sensitizer formed by the esterification of the esterified parent and diazonaphthoquinone sulfonyl chloride, higher resolution can be obtained, and the molecular weight A small size can make the degumming process easier and less prone to residue. Moreover, the preparation yield is high and the thermal stability is good. It is combined with the traditional film-forming resin to form a positive photoresist for LCD TFT with good storage stability and high resolution, so as to solve the problems of difficult refining, poor storage stability and low resolution of the current LCD photoresist of the diazonaphthoquinone system question.

The invention discloses a liquid food feeding device for patients with digestive system diseases, which mainly includes a ring plate, an esophagus and a pushing mechanism. A through hole is opened in the middle of the ring plate, and a push mechanism is fixedly installed on the said ring plate at the through hole. A liner is fixedly installed on the edge, and left and right symmetrical blocking pieces are fixedly installed on the outer wall at the inner side of the liner at the bottom end of the ring plate. The present invention has a reasonable structural design. The liquid food feeding device automatically feeds patients, and is more convenient to use for patients who cannot swallow. Moreover, the grains in the porridge can be crushed, and the feeding is smooth; the feeding device is convenient to fix, and it is not easy to fall off during use.

The invention discloses a production process based on intelligent automatic preparation of environmentally friendly rubber for vehicles, comprising the following steps: a. weighing raw materials: using a weighing machine to weigh each raw material; b. banburying: the weighed raw materials are put into the dense In the mixing machine, the mixed rubber is obtained by reacting in the internal mixer; c. Open refining: the mixed rubber is opened and refined to obtain a film, and then the film is sprayed or soaked with a release agent; d. The film is cooled; e. the film obtained in step d is cut by a cutting machine to obtain a semi-finished product; f. the semi-finished product is vulcanized by a vulcanization device to obtain a product. The invention can automatically tear off the burrs on the side edges of the workpiece, thereby effectively improving the work efficiency; and the burrs are removed by a tearing structure, and the burrs are not easy to remain and are cleaned up.
