The invention discloses automatic feeding equipment. The automatic feeding equipment is characterized in that the automatic feeding equipment comprises a rack, a vibrating feeding disc, an adding device and a discharging track; the vibrating feeding disc comprises a first vibrating feeding disc and a second vibrating feeding disc; the first vibrating feeding disc is connected with the dischargingtrack through a first connecting track; the second vibrating feeding disc is connected with the discharging track through a second connecting track; the adding device comprises a first adding device and a second adding device; a discharging opening of the first adding device is formed in the upper portion of the first vibrating feeding disc, and a discharging opening of the second adding device isformed in the upper portion of the second vibrating feeding disc; and each set of vibrating feeding disc is further provided with a material lacking induction device, one side of each material lacking induction device is installed on the rack, and the other side of each material lacking induction device abuts against the interior of the vibrating feeding disc on the corresponding side. The automatic feeding equipment improves the feeding efficiency and the feeding quality.

The invention discloses a loudspeaker and an audio device. The loudspeaker comprises a support; a magnetic circuit system which is mounted on the bracket and is provided with a magnetic circuit gap and a conical basin vibration space arranged on the inner side of the magnetic circuit gap; a vibration system which comprises a vibrating diaphragm, an elastic wave and a voice coil, wherein the vibrating diaphragm comprises a conical basin part and an elastic connecting part connected to the periphery of the conical basin part, the outer edge of the elastic connecting part is connected to the support, the bottom of the conical basin part is arranged in the conical basin vibration space, and the elastic wave is connected with the conical basin part and the magnetic circuit system, one end of the voice coil is connected to the elastic connecting part, and the other end of the voice coil extends into the magnetic circuit gap. Thus, the distance between the diaphragm and the upper end of the vibration system can be reduced on the premise of ensuring that the maximum amplitude of the voice coil has a relatively large value, so as to reduce the thickness of the loudspeaker.

The invention provides a knocking device for fiber bar stocks. The knocking device comprises a motor, a transmission gear, a cam, a driven wheel, a rocker and a knocking hammer. The motor is driven through the transmission gear, the cam is movably connected with a side plate of an arranging box through a bearing, and mutually matched with the driven wheel. The driven wheel is arranged in the middle of the rocker which is hinged to the side plate of the arranging box, and the lower end of the rocker is provided with the knocking hammer. According to the arrangement, when an arranging roller stirs and arranges the bar-shaped fibers, the arranging box is knocked continuously by the knocking device added on the knocking device for the fiber bar stocks so as to vibrate the bar-shaped fibers inside the arranging box; under the comprehensive action of vibrating and stirring arrangement, compactness of the bar-shaped fibers can be achieved, gaps among the bar-shaped fibers can be reduced as far as possible, so that the bar-shaped fibers can be arranged compactly and neatly, requirements of subsequent packing are met, and packing efficiency of the bar-shaped fibers can be effectively improved.

The invention provides a low-noise concrete brick forming vibration forming device and a forming machine. The vibration forming device comprises a connecting piece connected to a concrete brick formwork frame for directly transmitting vibration force to the concrete brick formwork frame, and a connecting piece fixed on the connecting piece. A vibrating mechanism used to provide a vibration source on the part. The advantages of the present invention are as follows: the vibration mechanism providing the vibration source is arranged on the connecting piece, and the connecting piece is directly connected with the concrete brick formwork frame. During operation, the vibration force of the vibration mechanism is directly transmitted to the concrete brick formwork frame through the connecting piece, which greatly improves the efficiency of the present invention. Reduce the energy loss in the vibration transmission process, so that the vibration mechanism does not need to work at a higher frequency; at the same time, it avoids the separation of the traditional concrete brick formwork frame and the vibration mechanism, resulting in the high-frequency collision of the two when the concrete brick is formed. ; Can reduce the vibration noise of the vibration forming device; can improve the vibration efficiency, reduce the vibration time, help the rapid forming of concrete bricks, and achieve high-efficiency and high-yield production.

The invention relates to a pouring molding machine for a light steel mixed prefabricated base plate with molding light fillers, and belongs to the field of building material machinery equipment. A steel mixed light molding plate middle steel mixed main rib molding area, a steel mixed longitudinal edge molding area and a light filler molding area correspondingly formed between the steel mixed light molding plate middle steel mixed main rib molding area and the steel mixed longitudinal edge molding area are respectively formed by concrete vibration molding separation plates of a vibration molding mechanism of the pouring molding machine. A discharging port of a concrete material hopper and a discharging port of a light filler material hopper of a material system correspond to the steel mixed main rib molding area, the steel mixed longitudinal edge molding area and the light filler molding area respectively, the discharging ports are controlled by a flow controller and respectively feed the concrete materials and the light filler materials into the corresponding steel mixed longitudinal edge molding area, the corresponding steel mixed main rib molding area and the corresponding light filler molding area, the light steel mixed prefabricated base plate with the molding light fillers is accordingly molded through vibration of the vibration molding mechanism, one-time simultaneous feeding molding on the two different materials is completed, and mechanical high-efficiency production on the light composite floor prefabricated base plate is achieved.
