For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0024] In one embodiment of the reciprocating straight vibration device of the present application, please refer to Figs. 1-3The reciprocating straight vibration device comprises a bottom plate 100, a forward bearing seat 200, a reverse bearing seat 300 and an electromagnet 110, the forward bearing seat 200 is connected with the bottom plate 100 through a first connecting plate 210, the reverse bearing seat 300 is connected with the bottom plate 100 through a second connecting plate 310, and the first connecting plate 210 and the second connecting plate 310 are both arranged in an inclined manner and have different inclined directions. The forward bearing seat 200 and the reverse bearing seat 300 are arranged in parallel and have a certain distance, and the bottom part is respectively provided with a first magnetic part 220 and a second magnetic part 320. The electromagnet 110 is arranged on the bottom plate 100 and is symmetrically located on one side of the first magnetic part 220 and the second magnetic part 320, and the electromagnet 110 has a certain gap with the first magnetic part 220 and the second magnetic part 320.

[0025] Specifically, the electromagnet 100 generates an alternating magnetic field after being powered on, thereby generating rapid reciprocating vibration. Since the electromagnet 110 is close to the first magnetic part 220 and the second magnetic part 320 connected to the bottom part of the forward bearing seat 200 and the reverse bearing seat 300 respectively, the electromagnet 110 and the first magnetic part 220 and the second magnetic part 320 have a magnetic effect, thereby driving the first magnetic part 220 and the second magnetic part 320 to vibrate, so as to realize the vibration of the forward bearing seat 200 and the reverse bearing seat 300. Since the forward bearing seat 200 and the reverse bearing seat 300 are connected with the bottom plate 100 through the inclined first connecting plate 210 and the second connecting plate 310 respectively, and have a certain distance therebetween, and the inclined directions of the first connecting plate 210 and the second connecting plate 310 are different, the forward bearing seat 200 performs reciprocating linear vibration around the axis of the first connecting plate 210, and the reverse bearing seat 300 performs reciprocating linear vibration around the axis of the second connecting plate 320, thereby avoiding the mutual collision between the forward bearing seat 200 and the reverse bearing seat 300 due to vibration, so as to avoid damage and noise. One electromagnet 110 realizes reciprocating linear vibration in two directions, simplifies the structure, saves the occupied space and cost of the device, ensures the consistency of vibration frequencies in two directions, improves the efficiency and stability, and achieves the effects of miniaturization and high-speed conveying.

[0026] Further, the bottom plate 100 is further provided with a limiting block 111, one end of the limiting block 111 is connected with the electromagnet 110, so that the electromagnet 110 is suspended on the bottom plate 100. Specifically, the limiting block 111 can increase the vibration amplitude and stability of the electromagnet 110 and reduce the shaking during vibration; different specifications of the limiting block 111 meet different vibration requirements.

[0027] Further, two counterweights 120 are arranged on the bottom plate 100, one of which is arranged on the side of the first magnetic member 220 away from the electromagnet 110, and the other of which is arranged on the side of the limiting block 111 away from the electromagnet 110. Specifically, the two counterweights 120 are arranged at the two ends of the electromagnet 110, so that the reciprocating linear vibration device runs more stably and safely when performing reciprocating linear vibration, and the safety of the device is improved.

[0028] Further, the first connecting plate 210 and the second connecting plate 310 are both provided with two, which are connected to the two ends of the positive bearing seat 200 and the reverse bearing seat 300 respectively. Specifically, the positive bearing seat 200 and the reverse bearing seat 300 maintain consistent swing and vibration frequency during their respective reciprocating linear vibration, and consume less energy in the resonance state. Preferably, the first connecting plate 210 and the second connecting plate 310 are elastic sheets. The elastic sheets have elastic restoring force after swinging, so that the positive bearing seat 200 and the reverse bearing seat 300 consume less energy during reciprocating linear motion.

[0029] Further, two fixing blocks 130 are further included, which are arranged at the two ends of the bottom plate 100 respectively. The fixing block 130 has a trapezoidal cross section, and has a first inclined surface 131 and a second inclined surface 132 on the two sides. The two first connecting plates 210 are connected to the first inclined surfaces 131 of the two fixing blocks respectively, and the two second connecting plates 310 are connected to the second inclined surfaces 132 of the two fixing blocks respectively. Specifically, the fixing block 130 has a trapezoidal cross section, so that the inclination directions of the first inclined surface 131 and the second inclined surface 132 are not parallel to each other. Since the first connecting plate 210 is connected to the first inclined surface 131, and the second connecting plate 310 is connected to the second inclined surface 132, the first connecting plate 210 and the second connecting plate 310 are stably inclined on the bottom plate 100 when not vibrating and swinging, and swing back and forth between the two fixing blocks 130 around the axis of the inclined surface when working, thereby driving the positive bearing seat 200 and the reverse bearing seat 300 to reciprocate linearly between the two fixing blocks 130.

[0030] Further, the bottom plate 100 is surrounded by a cover plate 140. Specifically, the cover plate 140 protects the reciprocating vibration device from normal work.

[0031] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
