The materials are substantially completely dispersed and pass through the gap d2 between the secondary baffle 35 and the bottom wall of the secondary vibration material cavity 3113 one by one. However, since d1 is greater than d2, and the feeding speed between the primary vibration component 2 and the secondary vibration component 3 is difficult to control to be completely equal, in practice, the feeding speed of the primary vibration component 2 is set to be slightly greater than that of the secondary vibration component 3, at this time, the material will form a pile between the secondary slide plate 312 and the secondary baffle 35, when the material pile reaches the height d3 of the material level sensor 36 from the bottom wall of the secondary vibration cavity 3113, the material level sensor 36 is triggered, the material level sensor 36 feeds back a signal to turn off the primary vibrator 22, and the secondary vibrator 32 continues to work until the height of the piled material gradually decreases to the height d2, and the material level sensor 36 detects that the height of the piled material decreases, and then sends out a signal again to turn on the primary vibrator 22. So repeated can realize the stable and even conveying and feeding of adhesion or easy hooking materials, and avoid the occurrence of material blockage.

The contact position of the first-stage sliding plate 212 and the bottom wall of the first vibration bin is located outside the feeding bin 1 (such as the front side of the first-stage baffle 15 in fig. 4), and the distance from the first-stage discharge port 2112 is greater than 100 mm. A material guide plate 14 is arranged above the hinge of the first-stage sliding plate 212 and the feeding bin 1 and used for preventing materials from falling below the first-stage sliding plate 212. The contact position of the secondary slide plate 312 with the bottom wall of the second vibratory bin is located at the rear side of the secondary baffle 35 (the rear side of the secondary baffle 35 as shown in fig. 4). And a material level sensor 36 is arranged on the secondary baffle 35 and used for monitoring the material accumulation height and feeding back a signal to control the start and stop of the primary vibrator 22.

According to the utility model discloses vibration material feeding unit 100 can realize when shutting down, and the material stops the forward motion at once, realizes the adhesion or easily colludes the stable even transport feed that links up the material, avoids taking place the putty. And the uniformly distributed materials output by the vibrating conveying device complete the visual detection and sorting work of the materials through the system control mechanism, the transmission identification mechanism and the execution mechanism.

In the third embodiment, the first step is that,

as shown in fig. 5 to 7, the present embodiment has substantially the same structure as the first embodiment, wherein the same reference numerals are used for the same components, and the difference is only that: in the first embodiment, the lower end of the primary sliding plate 212 is lapped on the bottom wall of the primary vibrating cavity 2113, the lower end of the primary sliding plate 212 is approximately in line contact or surface contact with the bottom wall of the primary vibrating cavity 2113, while in the third embodiment, the lower end of the primary sliding plate 212 is lapped on the side wall of the primary vibrating cavity 2113, and the primary sliding plate 212 is in point contact with the side wall of the primary hopper body 211.

Specifically, as shown in fig. 5, the vibration feeding device 100 according to the embodiment of the present invention includes: the primary vibrator 22, the primary hopper body 211, the primary slide plate 212, the guide plate 14, the feeding bin 1, the primary baffle 15, the first locking nut 21152, the first screw 21151, the second screw 21231 and the second locking nut 21232.

Wherein, one-level vibrator 22 is located feeding storehouse 1 below, and one-level hopper body 211 links firmly on one-level vibrator 22, and one-level slide 212 one end is passed through hinged joint on feeding storehouse 1, and the other end edge is taken on the support edge 2114 of one-level hopper body 211 side, and the hinge top is equipped with the stock guide 14 that links firmly on feeding storehouse 1. The first-level sliding plate 212 is obliquely arranged, the hinge end is high, the other end is low, and the inclination angle of the first-level sliding plate 212 is about 20-40 degrees. The projection position of the lower end of the primary sliding plate 212 on the bottom wall of the primary vibrating cavity 2113 of the primary hopper body 211 is located between the projection position of the primary discharge port 2112 of the primary hopper body 211 and the projection position of the primary baffle 15 on the bottom wall of the primary vibrating cavity 2113, and the distance from the primary discharge port 2112 of the primary hopper body 211 is greater than 100 mm. The vertical distance from the lower edge of the primary baffle 15 to the primary slide plate 212 is d1, and the vertical distance from the lower end edge of the primary slide plate 212 to the bottom wall of the primary vibrating cavity 2113 is d 4. Wherein d1 is generally set to be 2-2.5 times of the maximum length of a single material, and d4 is set to be 0.8-1.0 times of the maximum length of the single material.

The contact point structure of the primary slide plate 212 and the primary hopper body 211 is shown in fig. 7. Threaded holes are formed in the primary sliding plate 212 and the primary hopper body 211, the first screw 21151 and the second screw 21231 penetrate through the threaded holes in the primary sliding plate 212 and the primary hopper body 211 respectively and are locked through the first locking nut 21152 and the second locking nut 21232, and the heads of the first screw 21151 and the second screw 21231 are in contact. The heads of the first screw 21151 and the second screw 21231 are in point contact.

In actual operation, the primary hopper body 211 vibrates, and the primary slide plate 212 vibrates by applying intermittent impact force to the primary slide plate 212 through contact between the heads of the first screw 21151 and the second screw 21231. The material in the feeding bin 1 enters the front side of the primary hopper body 211 through a gap d1 between the primary sliding plate 212 and the lower edge of the primary baffle 15, and is dispersed and conveyed under the vibration action of the primary sliding plate 212. Because d1 is 2 ~ 2.5 times the maximum material length, and the 20 ~ 40 inclination that first-level slide 212 set up, the material can not take place to block in the d1 position between first-level slide 212 and first-level baffle 15 lower limb. The material falls into the right side of the primary hopper body 211 and then continues to move to the right side to the primary discharge port 2112 of the primary hopper body 211 under the action of the primary vibrator 22. The material guiding plate 14 is used to prevent the material in the feeding bin 1 from directly entering the area below the first-level sliding plate 212, but still it is difficult to avoid a small amount of material from directly entering the area below the first-level sliding plate 212, so a gap d4 is provided between the non-hinged end (lower end) of the first-level sliding plate 212 and the bottom wall of the first-level vibrating cavity 2113 of the first-level hopper body 211, and the small amount of material falling into the area below the first-level sliding plate 212 can move to the outlet of the first-level hopper body 211 through the gap d4 under the vibration effect of the first-level hopper. The size of d4 can be adjusted by adjusting first screw 21151 and second screw 21231. The heads of the first screw 21151 and the second screw 21231 are contacted and impacted, so that abrasion can occur after long-time work, the screw can be conveniently replaced, and the maintenance is simple.

When the machine is shut down, because the projection position of the lower end of the first-stage sliding plate 212 on the bottom wall of the first-stage vibrating cavity 2113 is away from the first-stage discharge hole 2112 by a distance larger than 100mm, the material can immediately stop sliding to the next stage, so that the vibrating feeding device 100 of the embodiment can not only avoid material blockage by utilizing the vibration of the inclined first-stage sliding plate 212, but also avoid the problem that the feeding to the next stage cannot be stopped immediately when the machine is shut down due to the inclined first-stage sliding plate 212.

In conclusion, the vibration feeding device 100 of the embodiment can realize stable and uniform conveying and feeding of materials which are adhered or easily hooked, and avoids material blockage. And when the machine is stopped, the materials immediately stop moving to the next stage. The uniformly distributed materials output by the vibrating conveying device are subjected to visual detection and sorting work by the system control mechanism, the transmission identification mechanism and the execution mechanism.
