The invention relates to a food processing machine, comprising a cup body for food processing, a slurry cup for holding food, and a waste water box for collecting waste water, the cup body is provided with a slurry discharge rotary valve, the discharge The pulp rotary valve discharges the food or waste water in the cup to the pulp receiving cup or the waste water box. It is characterized in that the pulp discharge rotary valve includes a pulp discharge pipe, a valve core, and Drive device, the valve core is provided with a through hole, the through hole communicates with the pulp discharge pipe and the cup body, the valve core drives the pulp discharge pipe to move, and the pulp discharge pipe is connected to the slurry cup The reciprocating movement within the limited range between the position and the position of the waste water box is used to switch the pulp discharge and the waste water. Reduce the step of the rotary valve motor directly driving the position of the slurry discharge pipe, reduce the corresponding driving gears, reduce the corresponding cost, and reduce the number of accessories at the same time, and the corresponding failures caused by the failure of the accessories and the cooperation between the accessories will disappear. Product reliability.

The invention relates to a method for changing a floor-standing frame column to a beam-on-column structure, which belongs to the technical field of house structure transformation. Aiming at the problem of difficulty in improving the load-bearing structure in existing methods, the technical solution is as follows: a method for changing a floor-to-ceiling frame column to a beam-on-column structure , including the following steps: Step 1, install the upper and lower encircling column supports; Step 2, install the tie structure; Step 3, remove the part to be cut; Step 4, make a new fixed structure: make a new floor slab and a new support beam; 5. Remove the rest of the structure. The method of the present invention changes the floor frame column into a beam-on-column structure, and the established tie structure shares the bearing weight of the floor frame column, so that the structure remains stable during the demolition process, and a new floor slab and a new support beam integrated with the anchoring steel bar are established to become a new structure. The load-bearing structure removes the original landing frame column under the floor, so that a larger space is obtained under the floor, and a relatively stable structure is always maintained in each operation step.

The invention discloses a method for manufacturing a hollowed-out embossed hollow stone column through a computer. The method comprises the steps of the drawing of a hollowed-out embossed pattern by the computer, the programming of cutting positions of the hollowed-out embossment by the computer and the simulation of combination of the hollowed-out embossed patterns by the computer. As the methoduses computer drawing of a large-scale hollowed-out embossed pattern, the programming of the cutting positions, the simulation of the pattern combination and other modes and adopts computer typesetting manufacturing technology to simulate the large-scale hollowed-out embossed hollow stone column, the method simulates out the three-dimensional integral effect of the large-scale hollowed-out embossed stone column and also represents the hollowed-out depth degree of stone carving. The method simulates the hollowed-out degree of an embossed pattern through the computer, further optimizes the hollowed-out pattern to ensure the hollowed-out quality of embossment before the carving operation, also can provide intuitional reference for the three-dimensional effect of the hollowed-out embossment of the large-scale stone column, better determines the cutting position of the embossment and has the advantages of accurate positioning, easy assembly, high mounting precision, high hollowed-out quality, and the like.

The invention provides a method for preparing in-situ graft modified rubber. In this method, the coupling agent is premixed and absorbed with the inert filler in advance, and the liquid coupling agent is converted into a solid form, which effectively ensures the coupling agent and the reinforcement The dispersion uniformity of the filler, and then by adjusting the process conditions to ensure that the high-temperature grafting reaction is carried out on the basis of the uniform dispersion of the reinforcing filler and the coupling agent, to ensure the efficiency, uniformity and stability of the reaction, and to ensure that the reaction is fully carried out. The method can be directly adopted in the production of mixed rubber, and at the same time can achieve the purpose of reducing production costs. The rubber products prepared by the method have excellent properties such as low heat generation, low pressure change, low creep, and aging resistance.
