A feed mechanism 10 according to an embodiment of the present invention is described below with reference to fig. 1-6, wherein the feed mechanism 10 is configured to shake apart and disperse the materials 1 before being sorted by the sorting apparatus 100, so that the sorting mechanism can identify and sort the materials 1 one by one during sorting.

As shown in fig. 2, the feeding mechanism 10 according to the embodiment of the present invention includes: a first vibratory hopper 2, a second vibratory hopper 42, a first vibrator 3, and a second vibrator 41.

The first vibrating hopper 2 has a feed opening 26 and at least one blanking opening 27 (see fig. 6), and at least one second vibrating hopper 42 is provided, and the second vibrating hoppers 42 are provided below the blanking openings 27 in a one-to-one correspondence. The first vibrator 3 is connected with the first vibration hopper 2, and the first vibrator 3 is used for driving the first vibration hopper 2 to vibrate. The second vibrator 41 is connected to the second vibration hopper 42, and the second vibrator 41 is configured to drive the second vibration hopper 42 to vibrate. That is, the first vibratory hopper 2 may have one or more blanking openings 27, and when there are a plurality of blanking openings 27, each blanking opening 27 is received by one second vibratory hopper 42 below. After the material 1 enters the feeding hole 26, the first vibration hopper 2 drives the material 1 to vibrate and disperse the material 1 under the driving of the first vibrator 3. The scattered materials 1 are moved to the blanking port 27 and then fall onto the second vibration hopper 42 from the blanking port 27. Under the driving of the second vibrator 41, the second vibration hopper 42 continues to vibrate the material 1 and further disperse the material 1.

In an embodiment of the invention, the first vibratory hopper 2 is vibratable at least in the X-direction, the second vibratory hopper 42 is vibratable at least in the Y-direction, the X-direction and the Y-direction have an angle therebetween, and both the X-direction and the Y-direction have an angle with the direction of gravity of the material 1. That is, the X direction does not coincide with the Y direction, the X direction does not coincide with the gravitational direction, and the Y direction does not coincide with the gravitational direction. For ease of description and labeling in the figures, the direction of gravity will be referred to hereinafter as the Z direction.

Therefore, the material 1 is dispersed at least in the X direction by the vibration of the first vibrator 3, and the material 1 is dispersed at least in the Y direction by the vibration of the second vibrator 42. Because material 1 can fully disperse, the interval between the material monomer (for example material 1 is tealeaves, and the material monomer is then single blade or the spherulite that the blade roll-up becomes) is enlarged, can reduce the condition that the material monomer colludes each other and link or bond. Like this during subsequent unloading, can reduce and even avoid the material 1 to block up the condition, also make follow-up convenient sorting mechanism to each material monomer inspection one by one when selecting separately, will expect with good material and bad material separately when convenient follow-up sorting, can also reduce and lead to the probability of selecting separately the error because of material 1 conglomeration when selecting separately, reduce and select separately the loss.

Here, it is proposed that the first vibratory hopper 2 is vibratable at least in the X direction, which means that the first vibratory hopper 2 is affected by the driving manner of the first vibrator 3, and the first vibratory hopper 2 may vibrate only in the X direction, or the first vibratory hopper 2 may vibrate in the X direction in combination with other directions. For example, in the example of fig. 2 described below, the first vibratory hopper 2 vibrates vertically while vibrating horizontally, i.e., the first vibratory hopper 2 vibrates in a combined manner of horizontal and vertical vibration. The second vibratory hopper 42 is vibratable at least in the Y direction, and the vibration condition is also that the second vibratory hopper 42 can vibrate only in the Y direction, and the second vibratory hopper 42 can also compound vibrations in other directions in the Y direction, which is not described herein again.

Optionally, the X direction is perpendicular to the Y direction. The surface formed by the X direction and the Y direction can be clamped with the gravity direction to form an acute angle, or the surface formed by the X direction and the Y direction can be vertical to the gravity direction, namely the X direction and the Y direction are vertical to the gravity direction two by two, so that under the same moving distance, the effective area of the vibration of the material 1 is large, the distance between the material monomers is long, and the phenomena of mutual hooking and conglomeration between the material monomers can be further avoided.

According to the feeding mechanism 10 provided by the embodiment of the invention, the two vibrators with different vibration directions are arranged, so that the material 1 can be dispersed in the X direction and the Y direction, and the material can be dispersed more uniformly. The structure of matching the two vibrators with the two vibrating hoppers is simple in structure and convenient to install. Because material 1 can fully disperse, can solve the putty problem of follow-up unloading and the hourglass material problem when selecting separately, improved subsequent sorting effect.

In some embodiments, as shown in fig. 3, the first vibrator 3 includes: a transverse frame 36 and a drive member 31. The first vibratory hopper 2 is connected to a transverse frame 36 by a plurality of transmission shafts 37, a driving member 31 is arranged on the transverse frame 36, and the output end of the driving member 31 is connected with the first vibratory hopper 2. Here, the transverse frame 36 is a supporting structure of the first vibrator 3, and the transverse frame 36 and the transmission shaft 37 are used for supporting the vibration of the first vibrating hopper 2, so that a guide rail-slide block structure can be saved, and the assembly precision requirement can be reduced.

Further, one end of the transmission shaft 37 may be connected to the first vibratory hopper 2 through a pivot shaft, the other end of the transmission shaft 37 may also be connected to the transverse frame 36 through a pivot shaft, the transmission shaft 37 swings relative to the transverse frame 36 during the driving of the first vibratory hopper 2 by the driving member 31, and the constraint of the transmission shaft 37 limits the moving track of the first vibratory hopper 2 relative to the transverse frame 36.

Specifically, the lengths of the plurality of transmission shafts 37 are equal, so that the position of the first vibratory hopper 2 relative to the transverse frame 36 changes while the driving member 31 drives the first vibratory hopper 2 to move, but the posture of the first vibratory hopper 2 relative to the transverse frame 36 is not changed all the time. For example, in fig. 2, the inner plane of the first vibrating hopper 2 is always parallel to the upper surface of the transverse frame 36, so that the first vibrating hopper is prevented from tilting and dumping due to vibration.

Alternatively, the cross frame 36 includes a top frame 361 and four supports 362, the four supports 362 being connected to four corners of the top frame 361, each support 362 being connected to the first vibratory hopper 2 via one of the transmission shafts 37.

In one embodiment, as shown in fig. 2 and 3, the transmission shaft 37 has a first angle and a second angle relative to the support post 362, and the transmission shaft 37 swings between the first angle and the second angle during the driving member 31 drives the first vibratory hopper 2 to move. The angle between the first angle lower transmission shaft 37 and the pillar 362 is smaller (e.g., parallel), the angle between the second angle lower transmission shaft 37 and the pillar 362 is larger, and the angle between the first angle transmission shaft 37 and the pillar 362 is smaller than the angle between the second angle transmission shaft 37 and the pillar 362.

Under the influence of the structural constraint of the transmission shaft 37, the first vibration hopper 2 enables the material 1 to have a specific moving direction during the vibration process when vibrating the material 1. Referring to fig. 2, when the positive direction of the OX direction is left and the negative direction of the OX direction is right in fig. 2, and the transmission shaft 37 swings from right to left, the included angle between the transmission shaft 37 and the support 362 gradually decreases, that is, when the transmission shaft 37 swings from the second angle to the first angle, the direction thereof coincides with the positive direction of the OX direction. When the transmission shaft 37 swings from the second angle to the first angle, the first vibration hopper 2 moves upward while moving leftward, and the first vibration hopper 2 drives the material 1 to be thrown upward leftward. And when the transmission shaft 37 swings from the first angle to the second angle, the first vibratory hopper 2 moves downward while moving rightward. The material 1 thrown up at this time drops downwards under the action of gravity, and when falling onto the first vibratory hopper 2, the material 1 has moved to the left than before being thrown. Under multiple vibrations, material 1 scatters to the left gradually. In this embodiment, the feeding port 26 is located at the rightmost end of the first vibratory hopper, the blanking port 27 is located at the left side of the feeding port 26, and the material 1 gradually falls into the blanking port 27 in the process of vibrating and scattering to the left.

Optionally, the first vibrator 3 further includes: the elastic member 38, the elastic member 38 is plural and is disposed at the bottom of the transverse frame 36. Therefore, when the driving member 31 pulls the first vibratory hopper 2 to move, the elastic member 38 can absorb the vibration impact of the first vibrator 3 and the first vibratory hopper 2 to the outside as a whole. Moreover, since the elastic member 38 is still resilient when being pressed, the vibration direction of the first vibration hopper 2 is changed when the elastic member 38 is resilient, and the vibration direction of the first vibration hopper 2 is further diversified by the repeated expansion and contraction of the elastic member 38, that is, the resilient force of the elastic member 38 to the first vibration hopper 2, for example, the material 1 is vibrated in the X direction and simultaneously accompanied by the vibration in the up-down direction and the Y direction, which is favorable for further dispersing the material 1.

Alternatively, as shown in fig. 3, the driving member 31 is provided on the top frame 361, and the first vibratory hopper 2 is located between the four pillars 362 and below the top frame 361. One spring 38 is attached below each post 362.

Optionally, the resilient member 38 is a spring. The first vibrator 3 is fitted on the boss 6 through a spring (the boss 6 is provided on the below-mentioned frame 7), which facilitates replacement and maintenance debugging.

Specifically, as shown in fig. 3, the driving member 31 is a motor, and the first vibrator 3 further includes: an eccentric 33 and a connecting rod 34. The eccentric wheel 33 is connected to a motor, one end of the connecting rod 34 is rotatably connected to the first vibratory hopper 2, and the other end of the connecting rod 34 is rotatably connected to an eccentric shaft 331 of the eccentric wheel 33, the axis of the eccentric shaft 331 being perpendicular to the X direction. That is, the motor drives the eccentric wheel 33 to rotate, the eccentric shaft 331 rotates eccentrically when the eccentric wheel 33 rotates, and the connecting rod 34 directs the eccentric shaft 331 to the first vibratory hopper 2 for eccentric motion. In this embodiment, the eccentric shaft 331 rotates in a plane defined by the X direction and the Z direction, causing the first vibratory hopper 2 to vibrate in the Z direction as well as in the X direction. The motor is used as the driving piece 31, the driving force is large, the service life is long, and the vibration frequency can be improved.

Further, as shown in fig. 3, the motor is connected with the eccentric wheel 33 through a belt 32, a fixed seat 35 is provided on the first vibratory hopper 2, and two ends of the connecting rod 34 are respectively connected with the fixed seat 35 and the eccentric shaft 331.

In other embodiments, the driving member 31 may also be an electric push rod, and the electric push rod pushes the first vibrating hopper 2 to vibrate reciprocally.

In some embodiments, as shown in fig. 4-6, the first vibration hopper 2 has a plurality of blanking openings 27, and the plurality of blanking openings 27 are sequentially arranged along the X direction, so that the material 1 can be blanked through the plurality of scattered blanking openings 27 when being gradually scattered along the X direction, which is beneficial to further scattering the material 1 during subsequent vibration.

Specifically, the feed ports 26 and the blanking ports 27 are arranged along the X direction, and when there are a plurality of blanking ports 27, the feed ports 26 should be disposed at one end of the plurality of blanking ports 27 and should be located in the opposite direction of the force exerted on the first vibratory hopper 2 by the driving member 31. In the example of fig. 4, the feed opening 26 is located at one end of the first vibratory hopper 2. The driving member 31 applies external force to the first vibration hopper 2 in the positive direction of OX, the material 1 falling onto the first vibration hopper 2 falls into the blanking port 27 after vibrating in the positive direction of OX under the action of the external force applied by the driving member 31, and the feeding port 26 is arranged on the first vibration hopper 2 and is positioned at one end of the plurality of blanking ports 27 in the negative direction of OX.

Alternatively, the areas of the plurality of blanking ports 27 increase in sequence in a direction away from the feed port 26, that is, the area of the blanking port 27 near the feed port 26 is small, and the area of the blanking port 27 far from the feed port 26 is large.

It can be understood that the hooking condition of the material 1 is relatively serious when the material 1 enters the first vibrating hopper 2, the material 1 with the hooking condition is fed from the feeding hole 26, when the vibration starts, the material 1 near the feeding hole 26 is relatively more densely stacked, and the material far away from the feeding hole 26 is relatively less dense due to being scattered. Therefore, the areas of the plurality of blanking ports 27 are arranged in the above manner, so that the blanking amount of the dense blanking ports 27 is reduced, and the blanking amount of the loose blanking ports 27 is increased, thereby facilitating the equalization of the blanking amounts of the plurality of blanking ports 27 and enabling the subsequent operation to achieve the equalization effect.

In some embodiments, as shown in fig. 4 and 6, a plurality of blanking ports 27 are provided on the first vibratory hopper 2, a material separating rib 28 is provided on the first vibratory hopper 2, the material separating rib 28 separates a plurality of material separating channels 280 in the first vibratory hopper 2, the plurality of material separating channels 280 are disposed in one-to-one correspondence with the plurality of blanking ports 27, one end of each material separating channel 280 is disposed toward the feeding port 26, and the other end of each material separating channel 280 is disposed toward the corresponding blanking port 27. The material 1 entering from the feed opening 26 is divided into a plurality of the dividing channels 280 when vibrating in the X direction, so that most of the material 1 distributed to different dividing channels 280 is discharged from different discharge openings 27. Therefore, most of the materials 1 are prevented from falling into the closer blanking port 27, namely, the phenomenon that the blanking of the near blanking port 27 is concentrated and the blanking of the far blanking port 27 is too little to influence the dispersion consistency of the subsequent materials 1 is avoided, and the dispersion uniformity of the materials 1 is further improved.

Specifically, the first vibration hopper 2 is provided with an initial distribution structure at the feeding hole 26, and the initial distribution structure is used for uniformly distributing the falling materials 1 into the plurality of distribution channels 280, so that the material distribution balance of the plurality of blanking holes 27 is further improved. Here, the preliminary structure may take various forms, and may be, for example, an adjusting plate 22 or the like described later.

Further, the material separating ribs 28 include X ribs 281, the X ribs 281 extend along the X direction, the X ribs 281 divide the plurality of material separating channels 280 into straight-line channels, the material separating channels 280 on two sides of the X ribs 281 respectively lead to different material dropping ports 27, so that the material separating ribs 28 have small obstruction to the material 1, and the material 1 has a long moving distance due to vibration.

Alternatively, the plurality of distributing channels 280 have the same size in the direction perpendicular to the X direction, such as the plurality of distributing channels 280 have the same width in the OY direction in fig. 6, thereby further improving the distribution balance of the plurality of blanking ports 27.

Alternatively, the plurality of blanking ports 28 gradually increase in width in the Y direction in a direction away from the feed opening 26, one end of the X rib 281 is disposed adjacent to the feed opening 26, and the other end of the X rib 281 extends to one of the blanking ports 27.

Further optionally, the dispensing rib 28 further comprises: and the Y rib 282 extends along the Y direction, and the Y rib 282 is arranged on the side of the blanking port 27 far away from the feed port 26.

In the example of fig. 4, three blanking ports 27 are provided on the first vibratory hopper 2, and the three blanking ports 27 are arranged at intervals in the X direction. The three sets of separating ribs 28 are provided, the separating rib 28 corresponding to the farthest blanking port 27 includes only the Y rib 282, and the separating ribs 28 corresponding to the other two blanking ports 27 include the X rib 281 and the Y rib 282. The two X-ribs 281 are arranged in parallel to divide the material 1 shaken out from the feed opening 26 into three streams. Each Y-stop 282 is disposed on a side of the corresponding drop opening 27 away from the feed opening 26.

In some embodiments, as shown in fig. 5, the first vibratory hopper 2 comprises: hopper box 21, a feeding section of thick bamboo 25 and regulating plate 22, hopper box 21 level setting and top are opened, and feeding section of thick bamboo 25 communicates from top to bottom and connects on hopper box 21, and feeding inlet 26 is constituteed to feeding section of thick bamboo 25's top, and feeding section of thick bamboo 25's below is just setting up hopper box 21, and regulating plate 22 is at least one, and regulating plate 22 slope sets up in feeding section of thick bamboo 25. Therefore, after the material 1 falls into the feeding cylinder 25, under the blocking action of the adjusting plate 22, partial falling energy is absorbed, the bouncing height is reduced, and the material 1 is prevented from being bounced seriously. And the adjusting plate 22 is contacted with the material 1, so that the material 1 is scattered more uniformly, and the material 1 falling on the adjusting plate 22 can slide downwards along the adjusting plate 22 under the action of gravity.

Specifically, as shown in fig. 5, the adjusting plate 22 is connected in the feeding cylinder 25 through the hinge 24, and the angle of the adjusting plate 22 is adjustable, so that the angle can be adjusted according to different materials 1, the materials 1 are guaranteed to be sufficiently scattered, and the economical efficiency and the applicability of the product are improved. Specifically, the inclination angle of the adjusting plate 22 is lower than 0 degree, that is, the position of the adjusting plate 22 at one end of the hinge 24 is high, and the position of the adjusting plate 22 at the end far away from the hinge 24 is low, so that the material 1 can slide down conveniently.

Further, a layer of energy absorbing material such as sponge can be disposed on the upper surface of the adjusting plate 22, so as to further improve the energy absorbing effect and reduce the bounce of the material 1.

Specifically, as shown in fig. 5, the first vibratory hopper 2 includes: the telescopic piece 23, telescopic piece 23 one end is connected on the internal wall face of feed cylinder 25, and the other end of telescopic piece 23 is connected on the lower surface of regulating plate 22, and the length of telescopic piece 23 is adjustable in order to adjust the inclination of regulating plate 22. The telescopic member 23 can adjust the angle of the adjusting plate 22 on one hand, and can support the adjusting plate 22 on the other hand, so that the adjusting plate 22 is prevented from being damaged or failing in angle adjustment under long-term impact.
