The invention discloses a convective dryer for biodegradable plastic particles, which belongs to the field of drying biodegradable plastics. A convective dryer for biodegradable plastic particles includes a convective dryer body, and a suction device is fixedly installed inside the convective dryer body. Dust diffusion drying bag, the upper and lower inner walls of the dust absorption diffusion drying bag are rotated and connected with a diffusion convection air cover, which can make biodegradable plastic particles in the dust absorption diffusion drying bag through the cooperation of the diffusion convection air cover and the convection isolation drying system. Suspension separation state, and then effectively realize the convective suspension isolation and drying of biodegradable plastic particles, thereby reducing the contact between biodegradable plastic particles and their contact with the dust-absorbing diffusion drying bag, and reducing the adhesion of dust and dust on the wall of biodegradable plastic particles during drying. Reduce the probability of impurities, effectively avoid the contamination of biodegradable plastic particles, and improve the drying quality of the convection dryer body.

The invention relates to the field of electronic connectors. Electronic connector packaging equipment comprises a packaging rack, a carrier tape conveying device, a diaphragm conveying device, a carrier tape slideway device and carrier tape pressing devices, wherein the carrier tape conveying device, the diaphragm conveying device and the carrier tape slideway device are all fixed on the packagingrack; the carrier tape conveying device and the diaphragm conveying device are connected with the carrier tape slideway device; the number of the carrier tape pressing devices is multiple, and the plurality of carrier tape pressing devices are all fixed to the carrier tape slideway device and are connected with connector diaphragms; the carrier tape conveying device and the diaphragm conveying device are respectively used for feeding carrier tapes and the diaphragms; the carrier tape slideway device is used for conveying the carrier tapes and the diaphragms; the carrier tape pressing devicesare used for press fitting between the diaphragms and the carrier tapes; and according to the equipment, by arranging the carrier tape pressing devices, firm connection between the diaphragms and thecarrier tapes is guaranteed, and the packaging quality of an electronic connector is improved.

The invention discloses a swing switching wall base comprising a fixed base, a water split body capable of rotating relative to the fixed base and a socket capable of rotating relative to the fixed base, wherein the fixed base is provided with a water split cavity, a water inlet channel and at least one water path; the water split body is rotatably arranged and connected with the water split cavity; the tail end of the water split body penetrates out of the water split cavity and is fixedly connected with the socket; the water split body is driven by the swing of the socket to swing; and the control on a water outlet switch or the switch for the water path can be realized by the relative swing between the water split body and the fixed base. The wall base not only has the fixing function,but also has the function for controlling water outlet.

The invention relates to a device and a method for synthesizing Coriolis flowmeter vibration starting signals through all-digital waveforms. The device comprises a microcontroller, a direct digital frequency synthesizer (DDS), a multiplication digital-analog converter (MDAC) and an audio power amplifier. After the device is powered on, the DDS is controlled by the microcontroller to constantly synthesize and output 1-Hz square wave signals, at the same time, the microcontroller writes control words into the MDAC, the square wave signals passing the MDAC are subjected to amplitude modulation and amplification according to size of the control words and amplified by a fixed multiple through work, and final amplitude of the square wave signals is adjusted to 9 Vpp. The signals are input into a flow tube to realize quick vibration starting of the flow tube.
