The invention belongs to the technical field of battery manufacturing, and in particular relates to a film sticking device. The film laminating equipment includes a frame, two film pressing rollers and two film feeding mechanisms; the frame is provided with a feeding channel and a discharging channel, and there is a film bonding channel between the feeding channel and the discharging channel; the two film feeding mechanisms are respectively located on the upper and lower sides of the film bonding channel. On the side, there is a film laminating port between the two laminating rollers, and the film laminating channel runs through the film laminating port. The feeding channel transports the bare material to the film laminating port, the two film feeding mechanisms transport the insulating film to the film laminating port respectively, and the two film pressing rollers press the insulating film to the front and back sides of the bare material, so as to realize the front and back sides of the bare material at the same time Film application, the insulating film can be pasted on the front and back of the bare material without flipping the bare material during the film sticking process. The film sticking equipment does not need to be equipped with a turning mechanism, the structure of the film sticking equipment is simpler, the difficulty of equipment operation control is reduced, and it reduces the need to turn over the bare material. The process improves the efficiency of film sticking.

The invention relates to the technical field of electronic component crimping equipment, and discloses an automatic crimping machine for electronic components. The automatic crimping machine comprisesa base, wherein a fixed seat is fixedly mounted at the front part of the upper surface of the base, and a cable processing device is fixedly mounted at the top of the right side of the fixed seat. The processing process of a wire is divided into four areas through the arrangement of a square rotating body and a fixing device, so that the cutting, peeling and crimping of the connecting terminal and the releasing process of the wire can be simultaneously performed, and the production efficiency of the crimping machine is greatly improved. In addition, the equipment operation control difficultyis reduced through the fixed rotation angle, the positioning accuracy between the wire and the connecting terminal is improved, and the product production quality is improved. Meanwhile, the wire is fixed by the fixing device, the wire is prevented from moving when the connecting terminal is fixed by sleeving and stamping, the wire is further prevented from being inserted into the connecting terminal too deeply or too shallowly, and the probability of insufficient fixation of the connecting terminal is reduced.

The present invention provides a nitrile hydratase industrial fermentation production prescription and a fermentation method. The prior nitrile hydratase industrial fermentation base fluid is used asa base, trisodium phosphate is added into the fermentation base fluid and the adding quantity is 0.13 percent to 0.15 percent of the weight of fermentation fluid. The prescription is adopted, after material is put and dissolved, sodium hydroxide is used to adjust the pH value to be 7 to 8; then disinfection is processed; when the temperature rises till 110 DEG C to 120 DEG C, the pressure is keptfor 10 to 20 minutes; subsequently, the temperature of the material in a fermentation tank is reduced to 20 DEG C to 30 DEG C fast; when a strain meets the index, the subcultivation is processed for the fermentation production. The method can improve the activity of the nitrile hydratase by more than 50 percent and synchronously can ensure that the fermentation production period of the fermentation tank is shortened by one third, which does not require adding new devices and is simple for carrying out; compared with the feeding methods of feeding sugar, feeding sodium hydroxide, etc., the method of the present invention reduces additional work and the operation and control difficulty brought by feeding during the course of the fermentation and eliminates the occurrence of the status that the fermentation tank is infected bacteria caused by feeding.

The invention relates to a method for chemically synthesizing acetic acid by using methanol low pressure carbonyl and a device thereof, belonging to the technical field of chemical engineering. The method comprises: methanol and carbon monoxide firstly react in a reactor filled with reaction liquid to generate the acetic acid, and then the reaction liquid enters a multifunctional tower to be processed by flash evaporation and lightness removal to lead overhead fraction of the multifunctional tower to enter a condenser, so that part of light phase in the condensate liquid flows and returns to a lightness removing section of the multifunctional tower, and heavy phase returns to the reactor to continuously take part in the reaction. The method combines the functions of the existing evaporator and lightness removing tower into the multifunctional tower, so as to simplify the flow route of acetic acid preparation, shorten the returning route of catalyst, be beneficial to maintaining the stable property of the catalyst and reducing the loss of the catalyst; the existing evaporator and lightness removing tower are combined into a whole, so that the equipment investment is reduced and thedifficulty of operation and control can be lowered.

The invention discloses a generation method of synchronous fixed-frequency current phasors in a full-inverter type microgrid. A GPS satellite timing signal is used as a global synchronous reference signal so as to control the synchronous current phasors, which are constant in output frequency and coincident in phase, of all schedulable distributed power inverters in the microgrid; according to a microgrid distributed power current-voltage droop control strategy, a current amplitude instruction is generated, a complete current phasor reference instruction is obtained with the combination of a phase instruction generated according to the global synchronous reference signal, and the amplitudes of the output current phasors of the schedulable inverters are adjusted, so that the network voltageoperates within a qualified range, and a synchronous fixed-frequency current source microgrid is formed. In the generation method, the advantages that the amplitude, the frequency and the phase of the output voltage (current) of the inverters are flexibly controllable are given full play to, and the control over the operation of the microgrid is simplified into a single voltage control, so that the operation control difficulty of the full-inverter type microgrid is obviously reduced.
