Inner wrapping betel nut automatic packaging machine compromises a frame. The frame is provided with a blanking device, a betel nut transition, a bag bucket, a pusher, a bag rock and a suction bag mechanism. The blanking device includes a hopper for placing the betel nut, a vibration disk docked with the hopper outlet and a drive mechanism for driving the vibration disk. The discharging outlet of the vibration disk is docked with the betel nut transition bucket through a blanking track. The liftable position of the betel nut transition bucket is designed directly over the bug bucket. The suction bag mechanism is below the bag rock to suck up the bag body from the bag rock and convoy the bag to the bag bucket. The bag bucket is provided with a bag hot sealing device and a drawing mechanism which are below the bag bucket. The betel nut automatic packaging machine is simple in the structure, small in the occupying area, low in the input cost and suitable for the packaging of inner wrapping betel nut.

The invention discloses a production process of a foaming headset sleeve, and the production process comprises the following steps of a, preparation of materials: placing a well mixed material A and a well mixed material B respectively into a mixing kettle to be stirred; b, mixing: simultaneously placing the material A and the material B into the mixing kettle to be adequately stirred and mixed to form a mixed material; c, injection: continuously injecting the mixed material into a plurality of molds which are matched with each headset sleeve in shape through a mixing reaction kettle, arranging the molds in a single row in the transverse direction, and realizing automatic circular work through a transmission device; d, baking: automatically feeding the molds with the mixed material into a baking box to be baked through the transmission device; and e, demolding: pouring out the headset sleeves from the molds through the transmission device so as to enable the headset sleeves to be separated from the molds after baking is completed. Compared with the prior art, the production process of the foaming headset sleeve has the advantages of simplicity in production equipment, few in manufacturing procedures, simplicity in mold structure, long in service life, capability of being formed in one step, good forming quality, low production cost and low energy consumption.

The invention relates to the technical field of preparation of ferrite rubber and plastic magnetic powder, and discloses an efficient method for manufacturing ferrite rubber and plastic magnetic powder in view of the problems of complex procedures, long production cycle and high cost in the existing ferrite rubber and plastic magnetic powder manufacturing method The method is to put the pre-fired ball material with a particle size of ≤10mm directly into the ball mill for wet fine grinding, and then spray it into the drying and annealing kiln for annealing and calcination; and then disperse it through a 60-100 mesh screen to obtain ferrite rubber-plastic magnetic powder . On the one hand, the present invention adopts the drying and annealing method combining the drying and annealing integrated kiln and the slurry injection, and realizes the integration of drying and annealing on the basis of maintaining the performance of the ferrite rubber and plastic magnetic powder, saving dry grinding and deep pressing. The screening process after dehydration and drying shortens the production cycle and reduces the cost; on the other hand, combined with slurry spraying and drying, the wet fine grinding process is optimized, so that the particle size of more than 65% of the fine abrasives is more concentrated. Near the average particle size, the performance of the rubber-plastic magnetic powder after annealing is improved.

The invention discloses an anti-human GPC3 monoclonal antibody which is a specific high-affinity nanometer antibody developed by using human GPC3 as a target on the basis of a phage display technology. Compared with the prior art, the anti-human GPC3 monoclonal antibody is successfully prepared; the antibody has high specificity and high affinity, and can be combined with the human GPC3 expressedon the cell surfaces; and the anti-human GPC3 monoclonal antibody belongs to potential medicine for tumor immunotherapy.

The invention discloses a set of device for rapidly preparing stability test samples of gunpowder and explosives, and solves the problems that the stability test samples of the gunpowder and the explosives are low in preparation efficiency, long in consumed time and difficult to collect. The device comprises a knife rest part, a base part and a sample collecting part. According to the device, the samples can be prepared with the specification and size required by testing regulations once in continuous feeding and intermittent shearing stress manners; by virtue of a drawer type sample collector, the spattering of gunpowder particles can be effectively prevented. The device has the beneficial effects that the operation is easy, the time and the labor are saved, the test cycle can be greatly shortened, and the working efficiency is improved.
