[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0043] Reference below Figure 1-Figure 3 The vibrating feeding device 100 according to an embodiment of the present invention is described, wherein the vibrating feeding device 100 of this embodiment may be a vibrating feeding device 100 for a color sorter.
[0044] like Figure 1As shown, the vibrating feeding device 100 according to an embodiment of the present invention comprises: a feed bin 1, a primary vibrating hopper 21 and a primary vibrator 22, wherein the primary vibrating hopper 21 and the primary vibrator 22 are the primary vibrating components 2 of the vibrating feeding device 100.
[0045] Specifically, the feed bin 1 is formed with a discharge port 11, for example, the discharge port 11 can be formed at the bottom of the feed bin 1, and the discharge port 11 can be square; the first-level vibrating hopper 21 is arranged below the feed bin 1, for example, the first-level vibrating hopper 21 can be located directly below or obliquely below the feed bin 1. Of course, the present invention is not limited to this, as long as it can be ensured that the material falling from the discharge port 11 can enter the first-level vibrating hopper 21.
[0046] Furthermore, if Figure 1 As shown, the first-stage vibrating hopper 21 has a first-stage inclined conveying surface 2121, a first-stage horizontal conveying surface 2111 and a first-stage discharge port 2112. The first-stage inclined conveying surface 2121 is opposite to the discharge port 11 in the vertical direction. The first-stage inclined conveying surface 2121 is in the direction toward the first-stage discharge port 2112 (for example Figure 1 The first-level inclined conveying surface 2121 extends obliquely downward (from the back to the front direction shown in the figure), and the lower end of the first-level inclined conveying surface 2121 is connected to the first-level horizontal conveying surface 2111.
[0047] Here, “the lower end of the primary inclined conveying surface 2121 is connected to the primary horizontal conveying surface 2111” means that the material on the primary inclined conveying surface 2121 can be conveyed to the primary horizontal conveying surface 2111 through the lower end of the primary inclined conveying surface 2121. For example, the lower end of the primary inclined conveying surface 2121 can be directly connected to the primary horizontal conveying surface 2111, specifically, the lower end of the primary inclined conveying surface 2121 can be directly placed on the primary horizontal conveying surface 2111. For another example, the lower end of the primary inclined conveying surface 2121 can also be indirectly connected to the primary horizontal conveying surface 2111, specifically, the lower end of the primary inclined conveying surface 2121 can be connected to the primary horizontal conveying surface 2111 through a connecting channel or a connecting plane, and the material is conveyed to the primary horizontal conveying surface 2111 through the lower end of the primary inclined conveying surface 2121, the connecting channel or the connecting plane in sequence. For another example, the lower end of the first-level inclined conveying surface 2121 may also be separated from and disconnected from the first-level horizontal conveying surface 2111, as long as the materials on the first-level inclined conveying surface 2121 can be smoothly conveyed to the first-level horizontal conveying surface 2111. Specifically, the first-level inclined conveying surface 2121 is separated from the first-level horizontal conveying surface 2111 in the up and down directions, and the first-level inclined conveying surface 2121 extends downwardly at an angle to above the first-level horizontal conveying surface 2111. At this time, the materials at the lower end of the first-level inclined conveying surface 2121 can directly fall into the first-level horizontal conveying surface 2111 under the action of gravity.
[0048] The end of the primary horizontal conveying surface 2111 opposite to the primary inclined conveying surface 2121 (for example Figure 1 In other words, the primary discharge port 2112 is formed at the free end of the primary horizontal conveying surface 2111 (e.g. Figure 1 The first vibrator 22 is connected to the first vibration hopper 21, and the first vibrator 22 is used to drive the first vibration hopper 21 to vibrate so as to transport the material in the first vibration hopper 21 to the first discharge port 2112.
[0049] When the vibrating feeding device 100 is working, the first-level vibrator 22 drives the first-level vibrating hopper 21 to vibrate, and the material in the feed bin 1 falls into the first-level inclined conveying surface 2121 of the first-level vibrating hopper 21 through the discharge port 11 under the action of gravity, and then passes through the first-level horizontal conveying surface 2111, and is finally conveyed to the next process (such as the second-level vibrating component 3 described below) through the first-level discharge port 2112, thereby achieving the purpose of uniformly dispersing the material through vibration and conveying the material.
[0050] like Figure 4 As shown, the vibrating feeding device 100 may also include: a secondary vibrating material component 3, the secondary vibrating material component 3 may include a secondary vibrating material hopper 31 and a secondary vibrator 32, the secondary vibrating material hopper 31 is connected to the primary discharge port 2112, for example, the secondary vibrating material hopper 31 may be arranged below the primary discharge port 2112, the secondary vibrating material hopper 31 has a secondary discharge port 3112, and the material in the secondary vibrating material hopper 31 may be output through the secondary discharge port 3112; the secondary vibrator 32 is connected to the secondary vibrating material hopper 31, and the secondary vibrator 32 is used to drive the secondary vibrating material hopper 31 to vibrate so as to transport the material in the secondary vibrating material hopper 31 to the secondary discharge port 3112.
[0051] According to the vibrating feeding device 100 of the embodiment of the present invention, a secondary vibrating material component 3 is provided, so that the material after being vibrated and dispersed by the primary vibrating material component 2 can enter the secondary vibrating material component 3 through the primary discharge port 2112, and then be further vibrated and dispersed by the secondary vibrating material component 3, so that the distribution of the material during transportation is more uniform, thereby effectively avoiding the reduction of the recognition rate caused by material stacking, reducing the carry-out ratio in the rejection link, and further improving the sorting accuracy.
[0052] Among them, the vibrating feeding device 100 of the embodiment of the present invention is provided with a first-level inclined conveying surface 2121 extending obliquely downward. When the material is on the first-level inclined conveying surface 2121, it is not only subjected to the vibration of the first-level vibrating hopper 21 itself as the conveying power of the material, but can also slide under the action of gravity, thereby increasing the power of the material to move forward, ensuring the feeding speed of the vibrating feeding device 100, and avoiding material adhesion and accumulation.
[0053] At the same time, the vibrating feeding device 100 of the embodiment of the present invention is connected to the first-level horizontal conveying surface 2111 at the lower end of the first-level inclined conveying surface 2121. In this way, the material on the first-level inclined conveying surface 2121 can first be conveyed by the first-level horizontal conveying surface 2111 and then enter the next process through the first-level discharge port 2112. Compared with directly forming the first-level discharge port 2112 at the lower end of the first-level inclined conveying surface 2121, this embodiment can prevent the material on the first-level inclined conveying surface 2121 from directly sliding off and passing through the first-level discharge port 2112 to enter the next process when the vibrating feeding device 100 stops, thereby preventing the material (or raw material) containing impurities from flowing into the finished product.
[0054] The vibrating feeding device 100 according to the embodiment of the present invention can avoid material blockage, prevent foreign materials from flowing into the finished product, ensure the feeding speed, and achieve stable and uniform feeding of sticky and easily hooked materials.
[0055] In some embodiments of the present invention, Figure 1 As shown, the primary vibrator 22 may be an electromagnetic vibrator 22, and the primary vibrator 22 may include: a base 221, a drive shaft 222, a magnetic member 223, a coil 224, and an elastic reset member 225, wherein the drive shaft 222 is fixed to the base 221; the magnetic member 223 is connected to the primary vibration hopper 21, and the magnetic member 223 and the drive shaft 222 are arranged relative to each other along the axis direction of the drive shaft 222, and the magnetic member 223 is movable along the axis of the drive shaft 222; the coil 224 is sleeved on the outer side of the drive shaft 222, and the coil 224 is suitable for magnetizing the drive shaft 222 when power is turned on, so that the drive shaft 222 drives the magnetic member 223 to move along the axis of the drive shaft 222; one end of the elastic reset member 225 (for example Figure 1 The lower end of the elastic reset member 225 shown in FIG. 2 is fixedly connected to the base 221, and the other end of the elastic reset member 225 (for example Figure 1 The upper end of the elastic reset member 225 shown in the figure is connected to the first-stage vibrating hopper 21.
[0056] Optionally, the magnetic attraction member 223 may be an armature.
[0057] Optionally, the elastic reset member 225 may be an elastic sheet, which is arranged along an axial direction perpendicular to the driving shaft 222. Further, the elastic sheet may include two groups arranged at intervals along the front-rear direction.
[0058] In some embodiments, the vibrating feeding device 100 may further include: a primary hopper seat 23, a primary vibrating hopper 21 is fixed on the primary hopper seat 23, and a primary vibrator 22 is connected to the primary hopper seat 23. Thus, the primary vibrating hopper 21 can be easily installed. Specifically, Figure 1As shown, the first-stage vibrating hopper 21 includes a flat plate supporting portion and a connecting portion. The flat plate supporting portion is in the shape of a horizontally extending plate. The flat plate supporting portion is attached to and connected to the bottom wall of the first-stage vibrating hopper 21. The connecting portion is connected to the lower surface of the flat plate supporting portion and extends obliquely downward. For example, the connecting portion extends forward obliquely in the downward direction, and the lower ends of the connecting portion are respectively connected to the elastic member and the magnetic member 223.
[0059] In one embodiment of the present invention, Figure 1 As shown, the first-stage vibrating hopper 21 may include: a first-stage hopper body 211 and a first-stage slide plate 212. The first-stage hopper body 211 is transmission-connected to the first-stage vibrator 22. The first-stage vibrator 22 is used to drive the first-stage hopper body 211 to vibrate. A first-stage vibrating cavity 2113 is formed in the first-stage hopper body 211. The top of the first-stage vibrating cavity 2113 is open to facilitate receiving the material falling from the discharge port 11. One side (for example, the front side) of the first-stage vibrating hopper 21 is open to form a first-stage discharge port 2112 connected to the first-stage vibrating cavity 2113. The bottom wall of the first-stage vibrating cavity 2113 is horizontal to form the first-stage horizontal conveying surface 2111.
[0060] Furthermore, if Figure 1 As shown, at least part of the primary slide plate 212 is disposed in the primary vibration cavity 2113, that is, the primary slide plate 212 may be partially disposed in the primary vibration cavity 2113, or the primary slide plate 212 may be entirely disposed in the primary vibration cavity 2113; in the direction toward the primary discharge port 2112 (for example Figure 1 ), the first-level slide plate 212 extends obliquely downward, and the first-level slide plate 212 is rotatable around a first-level fixed axis, wherein the first-level fixed axis is close to the upper end of the first-level slide plate 212, and the lower end of the first-level slide plate 212 is placed on the first-level hopper body 211, and the overlapped end of the first-level slide plate 212 is separable from the first-level hopper body 211. For example, when the overlapped end of the first-level slide plate 212 is impacted by an external force, such as an impact from the first-level hopper body 211, the first-level slide plate 212 rotates around the first-level fixed axis, at which time, the overlapped end of the first-level slide plate 212 is separated from the first-level hopper body 211, that is, the overlapped end of the first-level slide plate 212 leaves the first-level hopper body 211 and does not contact the first-level hopper body 211, and the first-level slide plate 212 itself swings relative to the first-level hopper body 211 and pivots around the first-level fixed axis. Among them, the upper side surface of the first-level slide plate 212 forms a first-level inclined conveying surface 2121.
[0061] Optionally, the primary slide plate 212 is hinged to the feed bin 1. Thus, the primary slide plate 212 can be rotated around the primary fixed axis.
[0062] In some specific embodiments, Figure 1As shown, the lower end of the first-stage slide 212 can be placed on the bottom wall of the first-stage vibration cavity 2113. At this time, the lower end of the first-stage slide 212 can be detached from the bottom wall of the first-stage vibration cavity 2113. For example, when the first-stage slide 212 is impacted by external force, the first-stage slide 212 rotates around the first fixed axis, and the lower end of the first-stage slide 212 is detached from the bottom wall of the first-stage vibration cavity 2113.
[0063] The working process of the vibration feeding device 100 according to a specific embodiment is described below.
[0064] When the coil 224 is powered on, the magnetized drive shaft 222 and the armature (magnetic element 223) attract each other, and the armature moves toward the drive shaft 222, driving the first-stage hopper seat 23 and the first-stage vibrating hopper 21 to move, and the elastic sheet (elastic reset element 225) bends and deforms; when the coil 224 is powered off, the first-stage vibrating hopper 21 moves away from the drive shaft 222 along with the first-stage hopper seat 23 under the action of the elastic sheet restoring torque. Therefore, when the coil 224 is fed with periodic intermittent current, the first-stage vibrating hopper 21 reciprocates approximately along the axial direction of the drive shaft 222, and the first-stage vibrating hopper 21 is subjected to a force such as Figure 2 When the first-stage vibrating hopper 21 reciprocates, the bottom wall of the first-stage vibrating cavity 2113 will generate periodic impact force on the first-stage slide plate 212. The impact force on the first-stage slide plate 212 is as shown in FIG. Figure 3 As shown. Under the action of periodic impact force, the first slide plate 212 swings around the first fixed axis, and the material in the feed bin 1 slides downward under the swing of the first slide plate 212 and the action of gravity. The swing of the first slide plate 212 is conducive to shaking the material. The setting of the inclination angle of the first slide plate 212 increases the power of the material moving forward. Compared with the prior art, it not only increases the amplitude of the material, but also ensures that the feeding speed of the material will not be reduced, and finally enables the material to reliably and continuously enter the first horizontal conveying surface 2111 of the bottom wall of the first vibrating hopper 21, ensuring the normal conveying of the material.
[0065] In some embodiments of the present invention, Figure 1 As shown, the distance between the lower edge of the primary inclined conveying surface 2121 and the primary discharge port 2112 is not less than 100 mm. In other words, the distance between the lower edge of the primary slide plate 212 and the primary discharge port 2112 in the horizontal direction is not less than 100 mm. Figure 1 As shown, the horizontal distance L between the lower edge of the primary slide plate 212 and the primary discharge port 2112 can be 100 mm, 120 mm, 150 mm, 180 mm, etc. In this way, it can be prevented that when the vibration feeding device 100 stops, the material on the primary inclined conveying surface 2121 directly slides to the primary discharge port 2112 to enter the next step, thereby preventing the material (or raw material) containing impurities from flowing into the finished product, and realizing real-time rapid start and stop.
[0066] In some embodiments of the present invention, Figure 1 As shown, the angle between the primary inclined conveying surface 2121 and the horizontal plane can be in the range of 20° to 40°. In other words, the angle between the primary slide 212 and the horizontal plane can be in the range of 20° to 40°. For example, the angle between the primary slide 212 and the horizontal plane can be 25°, 30°, 35°, etc. In this way, when the material is on the primary inclined conveying surface 2121 of the primary slide 212, it is not only affected by the swinging force of the primary slide 212, but also by gravity, so that the power of the material moving forward can be increased, the feeding speed of the vibrating feeding device 100 can be guaranteed, and the material adhesion and accumulation can be avoided.
[0067] In some embodiments of the present invention, Figure 1 As shown, the projection of the lower edge of the primary inclined conveying surface 2121 on the horizontal plane can be located outside the projection of the discharge port 11 on the horizontal plane (for example Figure 1 That is, the projection of the lower edge of the first slide plate 212 on the horizontal plane can be located outside the projection of the discharge port 11 on the horizontal plane (for example, Figure 1 In other words, the lower edge of the primary slide plate 212 passes through and exceeds the front edge of the discharge port 11 in the direction from back to front, and is located on the inner side of the horizontal projection of the discharge port 11 compared to the lower edge of the primary inclined conveying surface 2121. This embodiment allows the material to reliably and continuously enter the primary horizontal conveying surface 2111 of the primary vibrating hopper 21, avoiding the material from being blocked between the lower edge of the discharge port 11 and the primary horizontal conveying surface 2111.
[0068] In some embodiments of the present invention, reference Figure 1 , the projection of the discharge port 11 on the horizontal plane is located inside the projection of the primary inclined conveying surface 2121 on the horizontal plane. In other words, the projection of the discharge port 11 on the horizontal plane is located inside the projection of the primary slide plate 212 on the horizontal plane. In other words, the projection of the primary inclined conveying surface 2121 on the horizontal plane can completely cover the discharge port 11. In this way, it can be ensured that all the materials falling from the discharge port 11 enter the primary inclined conveying surface 2121 of the primary slide plate 212 to avoid spilling of materials.
[0069] According to other embodiments of the present invention, Figure 5-Figure 7 As shown, the lower end of the first-stage slide plate 212 can also be placed on the side wall of the first-stage hopper body 211.
[0070] In some examples, such as Figure 5As shown, support parts 2122 may be formed on both sides of the lower end of the first slide plate 212 along the width direction, and the support parts 2122 are supported on the side walls of the first hopper body 211, and the support parts 2122 are rotatable relative to the side walls of the first hopper body 211 around the first fixed axis. Figure 5 As shown, a horizontally extending support edge 2114 is formed on the side wall of the primary hopper body 211, and the support portion 2122 may include: a vertical extension section 21221 and a horizontal extension section 21222, the vertical extension section 21221 extends vertically upward, the horizontal extension section 21222 is connected to the upper part of the vertical extension section 21221 and extends in the horizontal direction, and the horizontal extension section 21222 is placed on the support edge 2114. In this way, the support portion 2122 can be supported on the support edge 2114.
[0071] Furthermore, if Figure 6 and Figure 7 As shown, a first support member 2115 extending upward may be provided on the support edge 2114, and a second support member 2123 extending downward may be provided on the horizontal extension section 21222, and the first support member 2115 and the second support member 2123 are in point contact and abutment. In this embodiment, the force transmission between the primary hopper body 211 and the primary slide 212 is realized by point contact between the first support member 2115 and the second support member 2123, so that the stability of the force transmission between the primary hopper body 211 and the primary slide 212 can be improved, the force transmission loss can be reduced, and the effective impact of the primary hopper body 211 on the primary slide 212 can be ensured, the throwing amplitude of the material on the primary slide 212 can be increased, the shaking force of the material can be increased, the material stacking can be avoided, and the blockage can be reduced.
[0072] Furthermore, refer to Figure 7 As shown, the upper end surface of the first support member 2115 can be formed as a first arc-shaped surface protruding upward, and the lower end surface of the second support member 2123 can be formed as a second arc-shaped surface protruding downward, and the first arc-shaped surface abuts against the second arc-shaped surface. At this time, there is point contact between the first arc-shaped surface and the second arc-shaped surface, and the structure is simple and the force transmission is reliable.
[0073] Preferably, if Figure 7 As shown, a first threaded hole penetrating in the up-down direction may be formed on the support edge 2114, and the first support member 2115 may include a first screw 21151, and the first screw 21151 is threadedly connected to the first threaded hole. Figure 7As shown, a second threaded hole penetrating in the up-down direction may be formed on the horizontal extension section 21222, and the second support member 2123 includes a second screw 21231, which is threadedly connected to the second threaded hole. Furthermore, the threaded end of the first screw 21151 passes through the first threaded hole in a top-down direction, and the head of the first screw 21151 is located on the upper side of the support edge 2114. The threaded end of the second screw 21231 passes through the second threaded hole in a bottom-up direction, and the head of the second screw 21231 is located on the lower side of the horizontal extension section 21222. At this time, the head of the first screw 21151 and the head of the second screw 21231 are both located between the support edge 2114 and the horizontal extension section 21222, and the heads of the first screw 21151 and the second screw 21231 abut against each other, so as to realize that the lower end of the first-stage slide 212 is resting on the side wall of the first-stage hopper body 211, and realize the force transmission between the first-stage slide 212 and the first-stage hopper body 211.
[0074] In addition, since the first screw 21151 is threadedly connected to the first threaded hole, the relative height between the head end face of the first screw 21151 and the support edge 2114 can be adjusted by screwing the first screw 21151. Similarly, since the second screw 21231 is threadedly connected to the second threaded hole, the relative height between the head end face of the second screw 21231 and the horizontal extension section 21222 can be adjusted by screwing the second screw 21231. In this way, the relative height between the first slide plate 212 and the first slide plate 212 can be adjusted by screwing the first screw 21151 and the second screw 21231. The relative height between the bottom walls of the first-stage hopper body 211, for example, the distance d4 between the lowest edge of the first-stage slide 212 and the bottom wall of the first-stage hopper body 211 can be adjusted to between 0.8 times and 1 times the maximum size of a single material. In this way, when the material falls from the feed bin 1, if it does not fall onto the first-stage inclined conveying surface 2121 of the first-stage slide 212, but directly falls into the first-stage vibrating cavity 2113 of the first-stage hopper body 211, the material can move to the first-stage discharge port 2112 through the gap d4 between the lowest edge of the first-stage slide 212 and the bottom wall of the first-stage hopper body 211.
[0075] At the same time, since the first screw 21151 and the second screw 21231 achieve force transmission through abutment, when the first screw 21151 and the second screw 21231 work for a long time, they will cause wear due to impact and collision. In this embodiment, the first screw 21151 is threadedly connected to the first threaded hole, and the second screw 21231 is threadedly connected to the second threaded hole, so the first screw 21151 and the second screw 21231 can be easily replaced, and maintenance is simple.
[0076] Furthermore, if Figure 7As shown, the first support member 2115 may further include a first locking nut 21152, and the threaded end of the first screw 21151 may pass through the first threaded hole from top to bottom, and the first locking nut 21152 is sleeved on the threaded end of the first screw 21151 and is located at the lower side of the support edge 2114. Thus, the first locking nut 21152 may be used to lock the first screw 21151, so as to improve the connection stability and reliability between the first screw 21151 and the support edge 2114, and prevent the first screw 21151 from moving in the up and down directions during the impact between the first hopper body 211 and the first slide plate 212.
[0077] Furthermore, if Figure 7 As shown, the second support member 2123 may further include a second locking nut 21232, and the threaded end of the second screw 21231 may pass through the second threaded hole from bottom to top, and the second locking nut 21232 is sleeved on the threaded end of the second screw 21231 and is located on the upper side of the horizontal extension section 21222. Thus, the second locking nut 21232 may be used to lock the second screw 21231, so as to improve the connection stability and reliability between the second screw 21231 and the horizontal extension section 21222, and prevent the second screw 21231 from moving in the up and down directions during the impact between the first hopper body 211 and the first slide plate 212.
[0078] In some embodiments, Figure 5 As shown, the lower surface of the primary slide 212 is spaced from the bottom wall of the primary vibration cavity 2113, and the gap d4 between the lower edge of the primary slide 212 and the bottom wall of the primary vibration cavity 2113 is not less than 0.8 times the maximum size of a single material. Further, the gap d4 between the lower edge of the primary slide 212 and the bottom wall of the primary vibration cavity 2113 can be between 0.8 times and 1 times the maximum size of a single material. Thus, when the material falls from the feed bin 1, if it does not fall onto the primary inclined conveying surface 2121 of the primary slide 212, but directly falls into the primary vibration cavity 2113 of the primary hopper body 211, the material can move to the primary discharge port 2112 through the gap d4 between the bottom edge of the primary slide 212 and the bottom wall of the primary hopper body 211.
[0079] According to some embodiments of the present invention, referring to Figure 1 The feed bin 1 has a first side wall 12 and a second side wall 13, which are arranged in sequence and opposite to each other in the horizontal direction toward the primary discharge port 2122, and the discharge port 11 is formed between the lower edge of the first side wall 12 and the lower edge of the second side wall 13. The feed bin 1 may also include: a guide plate 14, one end of the guide plate 14 (for example Figure 1 The upper end of the guide plate 14 shown in FIG. 1 is connected to the first side wall 12, and the other end of the guide plate 14 (for example Figure 1The lower end of the guide plate 14 shown in the figure extends obliquely downward toward the second side wall 13, and the other end of the guide plate 14 extends above the primary inclined conveying surface 2121. In this way, the guide plate 14 can guide the materials in the feed bin 1 to the primary inclined conveying surface 2121, thereby preventing the materials from spilling or splashing outward.
[0080] Furthermore, if Figure 1 As shown, the feed bin 1 may further include: a primary baffle 15, the primary baffle 15 is connected to the second side wall 13 and extends vertically downward, and the primary inclined conveying surface 2121 extends toward the primary discharge port to pass through the lower part of the primary baffle 15. In other words, the lower end edge of the primary slide plate 212 passes through and exceeds the lower part of the primary baffle 15 in the direction from back to front, thereby allowing the material to reliably and continuously enter the primary horizontal conveying surface 2111 of the primary vibrating hopper 21, and preventing the material from being blocked between the lower edge of the primary baffle 15 and the primary horizontal conveying surface 2111.
[0081] Furthermore, if Figure 4 As shown, in the vertical direction (e.g. Figure 4 In the vertical direction shown in FIG. 1 ), the distance d1 between the lower edge of the primary baffle 15 and the primary inclined conveying surface 2121 can be between 2 and 3 times the maximum size of a single material. Thus, the material can pass smoothly between the primary baffle 15 and the primary inclined conveying surface 2121 to avoid material accumulation.
[0082] Preferably, if Figure 5 As shown, in the vertical direction (e.g. Figure 5 In the vertical direction shown in FIG, the distance d1 between the lower edge of the primary baffle 15 and the upper surface of the primary slide plate 212 is in the range of 2.5 to 3 times the maximum size of a single material. Thus, the material can pass smoothly between the primary baffle 15 and the primary inclined conveying surface 2121 to avoid material accumulation.
[0083] In some embodiments of the present invention, the secondary vibrating hopper 31 has a secondary inclined conveying surface 3121 and a secondary horizontal conveying surface 3111, the secondary inclined conveying surface 3121 is opposite to the primary discharge port 2112, and the secondary inclined conveying surface 3121 is in the direction toward the secondary discharge port 3112 (for example, Figure 4 The secondary inclined conveying surface 3121 extends obliquely downward (from the back to the front direction shown in the figure), the lower end of the secondary inclined conveying surface 3121 is connected to the secondary horizontal conveying surface 3111, and the other end of the secondary horizontal conveying surface 3111 opposite to the secondary inclined conveying surface forms a secondary discharge port (3112). That is, the secondary discharge port 3112 is formed at the free end (e.g. Figure 4When the secondary vibration material assembly 3 is working, the secondary vibrator 32 drives the secondary vibration material hopper 31 to vibrate, and the material in the primary vibration material assembly 2 enters the secondary inclined conveying surface 3121 from the primary discharge port 2112, and then passes through the secondary horizontal conveying surface 3111, and finally is conveyed to the next process through the secondary discharge port 3112, so as to achieve the purpose of uniformly dispersing the material and conveying the material through vibration.
[0084] The vibrating feeding device 100 of the embodiment of the present invention sets a secondary inclined conveying surface 3121 and a secondary horizontal conveying surface 3111 in the secondary vibrating hopper 31, so that the material on the secondary inclined conveying surface 3121 can enter the next process through the secondary discharge port 3112 after being conveyed by the secondary horizontal conveying surface 3111. Compared with directly forming the secondary discharge port 3112 at the lower end of the secondary inclined conveying surface 3121, this embodiment can prevent the material on the secondary inclined conveying surface 3121 from directly sliding to the secondary discharge port 3112 to enter the next process when the vibrating feeding device 100 stops, thereby preventing the material (or raw material) containing impurities from flowing into the finished product. At the same time, compared with only setting a first-level horizontal conveying surface 2111 in the secondary vibrating hopper 31, this embodiment can set a second-level inclined conveying surface 3121 that extends obliquely downward. When the material is on the second-level inclined conveying surface 3121, it is not only affected by the vibration of the second-level vibrating hopper 31 itself as the conveying power of the material, but can also slide under the action of gravity, thereby increasing the power of the material to move forward, ensuring the feeding speed of the vibrating feeding device 100, and avoiding material adhesion and accumulation.
[0085] In some embodiments of the present invention, Figure 4 As shown, the secondary vibrating hopper 31 may include: a secondary hopper body 311 and a secondary slide plate 312. The secondary hopper body 311 is transmission-connected to the secondary vibrator 32. The secondary vibrator 32 is used to drive the secondary hopper body 311 to vibrate. A secondary vibrating cavity 3113 is formed in the secondary hopper body 311. The top of the secondary vibrating cavity 3113 is open to facilitate receiving the material falling from the primary discharge port 2112. One side of the secondary vibrating hopper 31 (for example, the front side of the secondary vibrating hopper 31) is open to form the primary discharge port 2112 connected to the secondary vibrating cavity 3113. The bottom wall of the secondary vibrating cavity 3113 is horizontal to form the secondary horizontal conveying surface 3111.
[0086] Furthermore, if Figure 4 As shown, at least part of the secondary slide plate 312 is located in the secondary vibration material cavity 3113, that is, the secondary slide plate 312 can be partially located in the secondary vibration material cavity 3113, and the secondary slide plate 312 can also be completely located in the secondary vibration material cavity 3113; in the direction toward the secondary discharge port 3112 (for example Figure 4), the secondary slide 312 extends obliquely downward, and the secondary slide 312 is rotatable around the secondary fixed axis, the secondary fixed axis is close to the upper end of the secondary slide 312, the lower end of the secondary slide 312 is placed on the secondary hopper body 311, and the overlapping end of the secondary slide 312 is separable from the secondary hopper body 311. For example, when the overlapping end of the secondary slide 312 is impacted by an external force, such as an impact from the secondary hopper body 311, the secondary slide 312 rotates around the secondary fixed axis, at this time, the overlapping end of the secondary slide 312 is separated from the secondary hopper body 311, that is, the overlapping end of the secondary slide 312 leaves the secondary hopper body 311 and does not contact the secondary hopper body 311, and the secondary slide 312 itself swings relative to the secondary hopper body 311 and pivots around the secondary fixed axis. Among them, the upper side surface of the secondary slide 312 is formed as a secondary inclined conveying surface 3121.
[0087] In some embodiments, Figure 4 As shown, the lower end of the secondary slide plate 312 can be placed on the bottom wall of the secondary vibration cavity 3113. At this time, the lower end of the secondary slide plate 312 can be detached from the bottom wall of the secondary vibration cavity 3113. For example, when the secondary slide plate 312 is impacted by external force, the secondary slide plate 312 rotates around the secondary fixed axis, and the lower end of the secondary slide plate 312 is detached from the bottom wall of the secondary vibration cavity 3113.
[0088] In some embodiments, Figure 4 As shown, the secondary vibrating material assembly 3 may further include: a slide plate bracket 33, and the secondary slide plate 312 is hinged to the slide plate bracket 33, so that the secondary slide plate 312 can rotate around the secondary fixed axis.
[0089] In some examples, such as Figure 4 As shown, the angle between the secondary inclined conveying surface 3121 and the horizontal plane is in the range of 20° to 40°. In other words, the angle between the secondary slide 312 and the horizontal plane can be in the range of 20° to 40°. For example, the angle between the secondary slide 312 and the horizontal plane can be 25°, 30°, 35°, etc. In this way, when the material is on the secondary inclined conveying surface 3121 of the secondary slide 312, it is not only affected by the swinging force of the secondary slide 312, but also by gravity, so that the power of the material moving forward can be increased, the feeding speed of the vibrating feeding device 100 can be guaranteed, and the material adhesion and accumulation can be avoided.
[0090] In some embodiments of the present invention, Figure 4 As shown, the secondary vibration material assembly 3 may further include: a baffle support 34 and a secondary baffle 35, wherein the secondary baffle 35 is disposed on the baffle support 34, and the secondary baffle 35 extends vertically downward and extends to above the secondary horizontal conveying surface 3111. Thus, the discharging speed of the vibration feeding device 100 can be conveniently controlled.
[0091] Furthermore, if Figure 4 As shown, the distance d2 between the lower edge of the secondary baffle 35 and the secondary horizontal conveying surface 3111 is between 1.2 and 1.5 times the maximum size of a single material. Thus, it is possible to ensure that the materials passing through the secondary baffle 35 are not accumulated, and to achieve stable and uniform conveying of materials that are adhered or easily hooked, thereby avoiding material blockage.
[0092] In some examples of the present invention, the secondary vibration material assembly 3 may further include: a material level sensor 36, which is arranged on a side of the secondary baffle 35 away from the secondary discharge port 3112 (for example Figure 4 The material level sensor 36 is used to detect the material height in the secondary vibration hopper 31. Figure 4 As shown, the distance d3 between the material level sensor 36 and the secondary horizontal conveying surface 3111 is between 2 and 2.5 times the maximum size of a single material. When the material is piled up between the secondary slide plate 312 and the secondary baffle 35, when the material is piled up to a height detectable by the material level sensor 36, the material level sensor 36 is triggered, and the material level sensor 36 feedbacks a signal to shut down the primary vibration component 2, while the secondary vibration component 3 continues to work until the height of the accumulated material gradually decreases to the height of the lower edge of the secondary baffle 35. After the material level sensor 36 detects that the height of the accumulated material has decreased, it re-sends a signal to start the primary vibration component 2. This repetition can achieve stable and uniform feeding of materials that are adhered or easily hooked together, avoiding material blockage.
[0093] In some embodiments, the secondary vibrator 32 is an electromagnetic vibrator, see Figure 1 The secondary vibrator 32 may include: a base 221, a drive shaft 222, a magnetic member 223, a coil 224 and an elastic reset member 225, wherein the drive shaft 222 is fixed to the base 221; the magnetic member 223 is connected to the primary vibration hopper 21, the magnetic member 223 and the drive shaft 222 are arranged relative to each other along the axis direction of the drive shaft 222, and the magnetic member 223 is movable along the axis of the drive shaft 222; the coil 224 is sleeved on the outer side of the drive shaft 222, and the coil 224 is suitable for magnetizing the drive shaft 222 when power is turned on, so that the drive shaft 222 drives the magnetic member 223 to move along the axis of the drive shaft 222; one end of the elastic reset member 225 (for example Figure 1 The lower end of the elastic reset member 225 shown in FIG. 2 is fixedly connected to the base 221, and the other end of the elastic reset member 225 (for example Figure 1 The upper end of the elastic reset member 225 shown in the figure is connected to the primary vibrating hopper 21. Optionally, the magnetic member 223 can be an armature. Optionally, the elastic reset member 225 can be an elastic sheet, which is arranged along the axis direction perpendicular to the drive shaft 222. Further, the elastic sheet can include two groups arranged at intervals along the front-to-back direction.
[0094] In some embodiments, Figure 2 As shown, the secondary vibration material assembly 3 may further include: a secondary hopper seat 37, a secondary vibration material hopper 31 is fixed on the secondary hopper seat 37, and a secondary vibrator 32 is connected to the secondary hopper seat 37. Thus, the secondary vibration material hopper 31 can be conveniently installed. Specifically, as Figure 4 As shown, the secondary vibrating hopper 31 includes a flat plate support portion and a connecting portion. The flat plate support portion is in the shape of a horizontally extending plate. The flat plate support portion is attached to and connected to the bottom wall of the secondary vibrating hopper 31. The connecting portion is connected to the lower surface of the flat plate support portion and extends obliquely downward. For example, the connecting portion extends forward obliquely in the downward direction, and the lower ends of the connecting portion are respectively connected to the elastic member and the magnetic member 223.
[0095] The following will refer to Figure 1-Figure 7 The vibrating feeding device 100 according to three specific embodiments of the present invention is described.
[0096] Embodiment 1,
[0097] like Figure 1-Figure 3 As shown, the vibrating feeding device 100 of this embodiment is composed of a base 221, a locking nut 227, a driving shaft 222, a rear cover plate 226, a coil 224, an armature (magnetic element 223), a first-stage hopper body 211, a first-stage hopper seat 23, an elastic sheet (elastic reset element 225), an elastic base foot 228, a feed bin 1, a first-stage baffle 15, a first-stage slide plate 212 and a guide plate 14.
[0098] The rear cover plate 226 is connected to the base 221 by bolts. The drive shaft 222 and the rear cover plate 226 are threadedly matched, and the locking nut 227 is used to lock the relative position between the drive shaft 222 and the rear cover plate 226. The axis of the drive shaft 222 is colinear with the axis of the armature. The armature is fixedly connected to the primary hopper seat 23 by bolts, the primary hopper body 211 is connected to the primary hopper seat 23, the upper and lower ends of the elastic sheet are fixedly connected to the primary hopper seat 23 and the base 221 respectively, and the elastic sheet is perpendicular to the axis of the drive shaft 222.
[0099] One end of the first slide plate 212 is connected to the feed bin 1 by a hinge, and the other end of the first slide plate 212 is placed on the bottom wall of the vibration bin of the first hopper body 211. The first slide plate 212 forms an angle of about 20 to 40 degrees with the horizontal direction. The contact point between the first slide plate 212 and the bottom wall of the first vibration bin is set at the outer position of the discharge port 11 of the feed bin 1 ( Figure 1 A material guide plate 14 is provided above the hinge, and its main function is to ensure that the material can fall onto the primary slide plate 212, and to prevent the material from directly entering the vibration bin below the primary slide plate 212 without passing through the primary slide plate 212.
[0100] When the coil 224 is powered on, the magnetized drive shaft 222 and the armature attract each other, and the armature moves toward the drive shaft 222, driving the first-stage hopper seat 23 and the first-stage hopper body 211 to move, causing the elastic sheet to bend and deform; when the coil 224 is powered off, the first-stage hopper body 211 moves away from the drive shaft 222 along with the first-stage hopper seat 23 under the action of the elastic sheet restoring torque. Therefore, when the coil 224 is fed with periodic intermittent current, the first-stage hopper body 211 reciprocates approximately along the axis of the drive shaft 222, and the first-stage hopper body 211 is subjected to a force such as Figure 2 When the primary hopper body 211 reciprocates, the bottom wall of the vibrating bin will generate periodic impact force on the primary slide plate 212. The impact force on the primary slide plate 212 is as shown in FIG. Figure 3 As shown. Under the action of periodic impact force, the first slide plate 212 swings around the hinge, and the material in the feed bin 1 slides downward under the swing of the first slide plate 212 and the action of gravity. The swing of the first slide plate 212 is conducive to shaking the material. The setting of the inclination angle of the first slide plate 212 increases the power of the material moving forward. Compared with the prior art, it not only increases the amplitude of the material, but also ensures that the feeding speed of the material will not be reduced, and finally enables the material to reliably and continuously enter the first horizontal conveying surface 2111 formed by the bottom wall of the first hopper body 211 without being blocked between the lower edge of the first baffle 15 and the bottom wall of the vibration bin.
[0101] Among them, Figure 1 As shown, the design length L between the contact point between the first-level slide plate 212 and the bottom wall of the first-level vibration bin to the first-level discharge port 2112 of the vibration bin is greater than 100 mm. This can avoid the problem of materials continuing to slide along the first-level slide plate 212 during shutdown, and realize real-time rapid start and stop.
[0102] According to the vibrating feeding device 100 of the embodiment of the present invention, a first-level slide plate 212 is added to the first-level hopper body 211, and one side of the first-level slide plate 212 is connected to the side of the feed bin 1 through a hinge, and the other side of the first-level slide plate 212 is placed on the bottom wall of the first-level hopper body 211. At this time, the first-level slide plate 212 is tilted as a whole, with the hinge end high and the side in contact with the bottom wall of the first-level hopper body 211 low. The angle between the first-level slide plate 212 and the bottom wall of the first-level hopper body 211 is 20 to 40 degrees. The projection of the contact position of the first-level slide plate 212 with the bottom wall of the first-level hopper body 211 on the horizontal plane is located on the outside of the feed bin 1 (i.e. Figure 1 L is greater than 0), and the contact position between the first slide plate 212 and the bottom wall of the first hopper body 211 is greater than 100 mm from the first discharge port 2112 of the first hopper body 211. A guide plate 14 is provided above the hinge between the first slide plate 212 and the feed bin 1 to prevent materials from falling under the first slide plate 212.
[0103] The vibrating feeding device 100 according to the embodiment of the present invention can avoid material blockage, prevent materials from being transported to the next level in piles, realize real-time rapid start and stop, ensure that the feeding speed is not reduced, and realize stable and uniform feeding of materials that are sticky or easily hooked. The uniformly distributed materials output by the vibrating feeding device 100 according to the embodiment of the present invention are visually inspected and sorted by the system control mechanism, transmission identification mechanism, and actuator.
[0104] Embodiment 2:
[0105] like Figure 4 As shown, the structure of this embodiment is substantially the same as that of the first embodiment, wherein the same components are marked with the same reference numerals, and the only difference is that the vibration feeding device 100 in the first embodiment includes only a primary vibration material assembly, while the vibration feeding device 100 in the second embodiment includes two stages of vibration material assemblies: a primary vibration material assembly 2 and a secondary vibration material assembly 3.
[0106] Specifically, Figure 4 As shown, the vibrating feeding device 100 of the embodiment of the present invention includes: a first-level vibrator 22, a first-level hopper body 211, a first-level slide plate 212, a material guide plate 14, a feed bin 1, a first-level baffle 15, a slide plate bracket 33, a second-level slide plate 312, a second-level vibrator 32, a second-level hopper body 311, a baffle bracket 34, a second-level baffle 35 and a material level sensor 36.
[0107] Among them, the primary vibrator 22 is located below the feed bin 1, the primary hopper body 211 is fixedly connected to the primary vibrator 22, one end of the primary slide plate 212 is connected to the feed bin 1 through a hinge, and the other end is placed on the bottom wall of the primary vibration cavity 2113 of the primary hopper body 211, and a guide plate 14 is provided above the hinge, and the guide plate 14 is fixedly connected to the feed bin 1. The secondary hopper body 311 is fixedly connected to the secondary vibrator 32, one end of the secondary slide plate 312 is connected to the slide plate bracket 33 through a hinge, and the other end is placed on the bottom wall of the secondary vibration cavity 3113 of the secondary hopper body 311.
[0108] The primary slide plate 212 and the secondary slide plate 312 are both placed at an angle, with the hinge end being high and the contact end with the bottom wall of the primary vibration material cavity 2113 being low, with an inclination angle of about 20 to 40 degrees. The contact point between the primary slide plate 212 and the bottom wall of the primary vibration material cavity 2113 of the primary hopper body 211 is located at the front side of the primary baffle 15, and the contact point between the secondary slide plate 312 and the bottom wall of the secondary vibration material cavity 3113 of the secondary hopper body 311 is located at the rear side of the secondary baffle 35. The material level sensor 36 is mounted on the secondary baffle 35 and is higher than the lower edge of the secondary baffle 35. The vertical distance between the lower edge of the primary baffle 15 and the primary slide plate 212 is d1, the vertical distance between the lower edge of the secondary baffle 35 and the bottom wall of the secondary vibration material cavity 3113 is d2, and the vertical distance between the material level sensor 36 and the bottom wall of the secondary vibration material cavity 3113 is d3. Among them, d1 is generally set to 2 to 3 times the maximum length of a single material, d2 is set to 1.2 to 1.5 times the maximum length of a single material, and d3 is set to 2 to 2.5 times the maximum length of a single material.
[0109] During actual operation, the primary hopper body 211 (primary hopper body 211 and / or secondary hopper body 311) vibrates, exerting intermittent impact force on the primary slide plate 212 (primary slide plate 212 and / or secondary slide plate 312), causing the primary slide plate 212 to vibrate. The material in the feed bin 1 enters the front side of the primary hopper body 211 through the gap d1 between the primary slide plate 212 and the lower edge of the primary baffle 15, and the material is dispersed for the first time under the vibration of the primary slide plate 212. Since d1 is 2 to 3 times the maximum material length, and the primary slide plate 212 is set at an inclination angle of 20 to 40°, the material will not be blocked at the d1 port position. Under the action of the primary vibrator 22, the material continues to move to the right to the primary discharge port 2112 of the primary hopper body 211 and falls into the secondary slide plate 312. The height difference between the primary vibration material assembly 2 and the secondary vibration material assembly 3 is conducive to further dispersion of the material. Under the vibration of the secondary slide plate 312, the material is dispersed for the second time. At this time, the materials have been basically completely dispersed, and they 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 material component 2 and the secondary vibration material component 3 is difficult to control to be completely equal, in practice, the feeding speed of the primary vibration material component 2 is set to be slightly greater than the feeding speed of the secondary vibration material component 3. At this time, the materials will form an accumulation between the secondary slide plate 312 and the secondary baffle 35. When the materials accumulate to the height d3 of the level sensor 36 from the bottom wall of the secondary vibration material cavity 3113, the level sensor 36 is triggered, and the feedback signal of the level sensor 36 turns off the primary vibrator 22, while the secondary vibrator 32 continues to work until the height of the accumulated materials gradually decreases to the height d2. After the level sensor 36 detects that the height of the accumulated materials has decreased, it re-sends a signal to start the primary vibrator 22. In this way, the stable and uniform feeding of the materials that are adhered or easily connected can be achieved repeatedly to avoid blockage.
[0110] In short, according to the vibrating feeding device 100 of the embodiment of the present invention, a two-stage vibrating material assembly is provided, and a first-stage slide plate 212 is added to the first-stage hopper body 211 of the two-stage vibrating material assembly, one side of the first-stage slide plate 212 is connected to the fixed component by a hinge, and the other side is placed on the bottom wall of the vibrating material bin. The first-stage slide plate 212 is tilted as a whole, with the hinge end being high and the side in contact with the bottom wall of the vibrating material bin being low. The angle between the first-stage slide plate 212 and the bottom wall of the vibrating material bin is 20 to 40°. The contact position between the first-stage slide plate 212 and the bottom wall of the first vibrating material bin is located outside the feed bin 1 (such as Figure 4 The first-level baffle 15 is located in front of the first-level baffle 15, and the distance from the first-level discharge port 2112 should be more than 100mm. A guide plate 14 is provided above the hinge between the first-level slide plate 212 and the feed bin 1 to prevent the material from falling under the first-level slide plate 212. The contact position between the second-level slide plate 312 and the bottom wall of the second vibration bin is located at the rear side of the second baffle plate 35 (such as Figure 4The secondary baffle 35 is provided with a material level sensor 36 for monitoring the material accumulation height and providing feedback signals to control the start and stop of the primary vibrator 22.
[0111] According to the vibration feeding device 100 of the embodiment of the present invention, when the machine is stopped, the material immediately stops moving forward, and the material that is sticky or easily hooked is stably and evenly conveyed to avoid material blockage. The evenly distributed material output by the vibration conveying device is visually inspected and sorted by the system control mechanism, transmission identification mechanism, and actuator.
[0112] Embodiment 3,
[0113] like Figure 5-Figure 7 As shown, the structure of this embodiment is substantially the same as that of the first embodiment, wherein the same components are marked with the same figures, and the only difference is that in the first embodiment, the lower end of the first-stage slide 212 rests on the bottom wall of the first-stage vibration cavity 2113, and there is substantially line contact or surface contact between the lower end of the first-stage slide 212 and the bottom wall of the first-stage vibration cavity 2113, while the lower end of the first-stage slide 212 in the third embodiment rests on the side wall of the first-stage vibration cavity 2113, and there is point contact between the first-stage slide 212 and the side wall of the first-stage hopper body 211.
[0114] Specifically, Figure 5 As shown, the vibrating feeding device 100 of the embodiment of the present invention includes: a first-level vibrator 22, a first-level hopper body 211, a first-level slide plate 212, a guide plate 14, a feed bin 1, a first-level baffle 15, a first locking nut 21152, a first screw 21151, a second screw 21231, and a second locking nut 21232.
[0115] Among them, the primary vibrator 22 is located below the feed bin 1, the primary hopper body 211 is fixedly connected to the primary vibrator 22, one end of the primary slide plate 212 is connected to the feed bin 1 through a hinge, and the edge of the other end is placed on the support edge 2114 on the side of the primary hopper body 211, and a guide plate 14 fixedly connected to the feed bin 1 is provided above the hinge. The primary slide plate 212 is placed at an angle, with the hinge end high and the other end low, and the inclination angle of the primary slide plate 212 is about 20 to 40 degrees. The projection position of the lower end of the primary slide plate 212 on the bottom wall of the primary vibration cavity 2113 of the primary hopper body 211 is located between 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 vibration cavity 2113, and the distance from the primary discharge port 2112 of the primary hopper body 211 is greater than 100mm. The vertical distance between the lower edge of the primary baffle 15 and the primary slide plate 212 is d1, and the vertical distance between the lower edge of the primary slide plate 212 and the bottom wall of the primary vibrating chamber 2113 is d4. Wherein d1 is generally set to 2 to 2.5 times the maximum length of a single material, and d4 is set to 0.8 to 1.0 times the maximum length of a single material.
[0116] The contact point structure between the first slide plate 212 and the first hopper body 211 is as follows: Figure 7 As shown. The first slide plate 212 and the first hopper body 211 are provided with threaded holes, and the first screw 21151 and the second screw 21231 pass through the threaded holes of the first slide plate 212 and the first hopper body 211 respectively, and are locked by 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.
[0117] During actual operation, the primary hopper body 211 vibrates, and the first screw 21151 and the second screw 21231 contact each other to apply intermittent impact force to the primary slide plate 212, causing the primary slide plate 212 to vibrate. The material in the feed bin 1 passes through the gap d1 between the primary slide plate 212 and the lower edge of the primary baffle 15 and enters the front side of the primary hopper body 211, and is dispersed and transported under the vibration of the primary slide plate 212. Since d1 is 2 to 2.5 times the maximum material length, and the primary slide plate 212 is set at an inclination angle of 20 to 40°, the material will not be blocked at the position d1 between the primary slide plate 212 and the lower edge of the primary baffle 15. After the material falls into the right side of the primary hopper body 211, it continues to move to the right side under the action of the primary vibrator 22 to the primary discharge port 2112 of the primary hopper body 211. The guide plate 14 is used to prevent the material in the feed bin 1 from directly entering the area below the primary slide 212, but it is still inevitable that a small amount of material will directly enter the area below the primary slide 212, so a gap d4 is set between the non-hinge end (lower end) of the primary slide 212 and the bottom wall of the primary vibration cavity 2113 of the primary hopper body 211. A small amount of material falling into the area below the primary slide 212 will move to the outlet of the primary hopper body 211 through the gap d4 under the vibration of the primary hopper body 211. The size of d4 can be adjusted by adjusting the first screw 21151 and the second screw 21231. The heads of the first screw 21151 and the second screw 21231 are in contact and impact, and will be worn out after long-term work. This embodiment can easily replace the screws and is simple to maintain.
[0118] When the machine is shut down, since the projection position of the lower end of the first-stage slide 212 on the bottom wall of the first-stage vibration cavity 2113 is greater than 100 mm away from the first-stage discharge port 2112, the material can immediately stop sliding to the next stage. Therefore, the vibrating feeding device 100 of this embodiment can utilize the tilted first-stage slide 212 to vibrate to avoid material blockage, and avoid the problem of not being able to immediately stop feeding to the next stage when the machine is shut down due to the use of the tilted first-stage slide 212.
[0119] In summary, the vibrating feeding device 100 of this embodiment can realize stable and uniform feeding of materials that are sticky or easily hooked, and avoid material blockage. And it can be realized that when the machine is shut down, the material immediately stops moving to the next level. The uniformly distributed materials output by the above-mentioned vibrating conveying device are visually inspected and sorted by the system control mechanism, transmission identification mechanism, and actuator.
