DETAILED DESCRIPTION

[0065] In order to make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0066] The existing vibrating feeder is generally suitable for feeding of bulk granular materials, and the feeding effect is poor for sheet-shaped light and thin materials, and the materials are often stacked and discharged or fed in a lump, which is not suitable for the working condition requiring continuous and uniform feeding. Due to the physical characteristics and natural stacking state of the sheet-shaped light and thin materials, the materials actually lose the bulk characteristics, and due to the light and thin materials, the vibration throwing force of the vibrating feeder cannot be effectively transmitted to the materials, resulting in that the materials are accumulated in the vibrating feeder, and the actual feeding is actually relied on the extrusion of the subsequent feeding, and it is inevitable that the materials are discharged in a heap.

[0067] Alternatively, when the existing belt feeder is used for feeding of light and thin materials, the light and thin materials are naturally stacked, and thus it is inevitable that the materials are discharged in a heap.

[0068] Therefore, there is a need for a new feeding device form to solve the technical problem of the above-mentioned stacked feeding.

[0069] After repeated thinking and verification, the new feeding device is designed to solve the problems of the prior art.

[0070] The technical solutions of the new feeding device provided by the embodiments of the present application are described in detail below with reference to the drawings.

[0071] FIG. 1 is a side view of a feeding device according to an embodiment of the present application. FIG. 2 is a side view of another feeding device according to an embodiment of the present application. FIG. 3 is a top view of the feeding device according to an embodiment of the present application.

[0072] Referring to FIGS. 1-3, the present application provides a feeding device 100, which can at least include a first conveying mechanism 110 and a first blowing mechanism 120. The first conveying mechanism 110 can include a conveying turntable 111 rotatable in a horizontal direction. Specifically, the rotation direction W of the conveying turntable can be seen in FIG. 3. The first blowing mechanism 120, for example, can be a gas knife or other device that causes the material to move by blowing air. Other physical devices that can achieve this function are also available.

[0073] The conveying turntable 111 is used to receive the material entering from the material inlet 141 and to disperse the material during rotation. Specifically, in one possible implementation, the conveying turntable 111 can be opposite to the material inlet 141 of the feeding device 100.

[0074] It can be understood that in the embodiments of the present application, the amount of feeding can be controlled by controlling the rotation speed of the conveying turntable 111.

[0075] The first blowing mechanism 120 can be located above the conveying turntable 111. The first blowing mechanism 120 is used to blow at least part of the material on the conveying turntable 111 in a first direction L1 to separate from the conveying turntable 111 during rotation of the conveying turntable 111.

[0076] In one possible implementation, the first direction L1 is opposite to the direction of linear velocity of the conveying turntable 111 during rotation. The first blowing mechanism 120 blows in the opposite direction of the linear velocity of the conveying turntable 111, and the movement of the light and thin material against the wind speed is conducive to generating greater lift. The generation of lift is conducive to the peeling of the upper layer of material.

[0077] In this way, when the material is fed into the feeding device 100 through the material inlet 141, it is dispersed by the rotation of the conveying turntable 111. Since the first blowing mechanism 120 is provided above the conveying turntable 111, the blowing direction of the first blowing mechanism 120 is opposite to the direction of linear velocity of the conveying turntable 111. The first blowing mechanism 120 can peel the uppermost layer of material in the material.

[0078] It should be noted that in some embodiments, the conveying turntable 111 can be a disc, a ring disc, a rectangular disc, etc., or can also be a circular belt or a rectangular combined belt to achieve the feeding effect of the conveying turntable 111, as long as the feeding can be realized in a cycle. The first blowing mechanism 120 only blows the upper layer of the material to separate, and the remaining material can be moved to the first blowing mechanism 120 again through the circulating conveying turntable.

[0079] In the embodiment of the present application, the feeding device 100 further comprises a second conveying mechanism 130, wherein the first end 131 of the second conveying mechanism is connected with the conveying turntable 111, and the second end 132 of the second conveying mechanism extends along the second direction L2, and the second conveying mechanism 130 is used to receive the material separated from the conveying turntable 111 and convey the material along the second direction L2. The second conveying mechanism 130 can finally output the material stripped by the airflow to realize feeding.

[0080] It can be understood that in the embodiment of the present application, the blowing direction of the first blowing mechanism 120 is the third direction L3, as shown in FIGS. 1 and 2, and the third direction L3 and the first direction L1 can form a preset included angle A, wherein the preset included angle A can be an acute angle. The preset included angle A between the second direction L2 and the first direction L1 determines the thickness of the material stripping, and the second direction L2 and the first direction L1 are kept in an acute angle limit, which can avoid that the blowing of the first blowing mechanism 120 is mainly under pressure when the angle is too large, and the material cannot be stripped.

[0081] In the embodiment of the present application, the first direction L1 is the blowing direction of the first blowing mechanism 120, and the second direction L2 is the horizontal direction, and the included angle between the blowing direction of the first blowing mechanism 120 and the horizontal direction is the cutting angle of the airflow generated by the first blowing mechanism 120. By controlling the cutting angle of the airflow generated by the first blowing mechanism 120, the stripping thickness can be controlled.

[0082] It can be understood that the blowing direction of the first blowing mechanism 120 and the linear velocity direction of the blowing point position on the conveying turntable 111 are in reverse, and the conveying direction of the second conveying mechanism 130 is in forward.

[0083] Specifically, when the material is fed into the feeding device 100 through the feeding port 141, the material is dispersed by the conveying turntable 111. Since the first blowing mechanism 120 is arranged above the conveying turntable 111, the blowing direction of the first blowing mechanism 120 is opposite to the linear velocity direction of the conveying turntable 111, and the blowing direction of the first blowing mechanism 120 and the horizontal direction form a certain included angle (i.e., the preset included angle A), the first blowing mechanism 120 can strip the uppermost layer of the material and blow it to the second conveying mechanism 130 for conveying along the second direction L2 to realize the final discharge.

[0084] In the embodiments of the present application, the preset included angle A can be 10 degrees to 30 degrees. For example, the preset included angle A can be 10 degrees, 15 degrees, 20 degrees, 25 degrees or 30 degrees, and the present application is not limited thereto and is not limited to the above examples.

[0085] The first blowing mechanism 120 is arranged along the radial direction and the width of the conveying turntable 11. As shown in FIG. 3, the first blowing mechanism 120 is parallel to the width direction of the second conveying mechanism 130, so that the first blowing mechanism 120 can blow the materials on the conveying turntable in the maximum area and change the motion state of the materials from the conveying turntable to the second conveying mechanism.

[0086] It should be noted that the numerical values and numerical ranges involved in the present application are approximate values, and there can be a certain range of errors due to the manufacturing process, which can be considered negligible by those skilled in the art.

[0087] In the embodiments of the present application, the feeding device 100 can further include a cover 140. As shown in FIG. 1 or FIG. 2, the cover 140 can cover the second conveying mechanism 130 and at least part of the conveying turntable 111, and the first blowing mechanism 120 is arranged on the cover 140.

[0088] In addition, the cover 140 can be provided with an inlet 141 and an outlet 142, and the outlet 142 is close to the second end 132 of the second conveying mechanism.

[0089] In the embodiments of the present application, the feeding device 100 can further include at least one air outlet 143. The air outlet 143 can be located above the second conveying mechanism 130, and the air outlet 143 is used to release the airflow blown by the first blowing mechanism 120, so that the materials separated from the conveying turntable 111 fall onto the second conveying mechanism 130.

[0090] In one possible implementation, the air outlet 143 can be provided on the cover 140.

[0091] In addition, it can be understood that the airflow extension line of the blowing direction of the first blowing mechanism 120 and the extension direction of the second conveying mechanism 130 form an intersection point, and the orthographic projection of the air outlet on the second conveying mechanism 130 can be located between the second end 132 of the second conveying mechanism and the intersection point.

[0092] In addition, in some embodiments, the air outlet 143 can be further provided with an air suction device 1431, for example, a fan or the like.

[0093] It should be noted that in the embodiment of the present application, the air outlet 143 can be arranged along the fourth direction L4, and the fourth direction L4 can be towards the conveying turntable 111.

[0094] By arranging the air outlet 143 above the second conveying mechanism 130, the air flow blown by the first blowing mechanism 120 can be discharged through the air outlet 143, and the air flow along the interface line 134 of the fiber flow layer can be formed in the channel formed between the cover 140 and the second conveying mechanism 130, and the light and thin materials such as dust can be sucked and removed to prevent suspension in the air.

[0095] Specifically, the stripped materials are blown into the second conveying mechanism 130, and the air outlet 143 is arranged above the second conveying mechanism 130 and is arranged obliquely towards the first blowing mechanism 120, and after the air blown by the first blowing mechanism 120, the air flow at the air outlet 143 gradually flows along the interface line 134 of the fiber flow layer.

[0096] It can be understood that the position of the air outlet 143 is related to the blowing direction of the first blowing mechanism 120 and the size of the air flow, and the position of the air outlet 143 can be adjusted and determined through actual test, so that the air blown by the first blowing mechanism 120 can be released, and the air flow in the same direction as the second direction L2 can be formed in the channel, and the materials can be quickly separated from the air flow and fall onto the second conveying mechanism 130 by gravity, and the release of the air flow will not interfere with the movement of the materials, and the thin and light materials such as dust can be further removed.

[0097] In the embodiment of the present application, the second conveying mechanism 130 can be a conveying belt, which can be a rubber conveying belt, a metal conveying belt, but is not limited to the above two, for example, it can also be a plastic conveying belt, etc.

[0098] It can be understood that, as shown in FIG. 3, in the embodiment of the present application, a filter screen 144 can also be arranged at the position of the air outlet 143, and the filter screen 144 can play a screening and isolation role.

[0099] Referring to FIGS. 1 and 2, in the embodiment of the present application, the first conveying mechanism 110 can further include a driving member 112, wherein the driving member 112 is used to drive the conveying turntable 111 to rotate in the horizontal direction.

[0100] The feeding device 100 can further include a material inlet channel 150, wherein the material inlet channel 150 is communicated with the material inlet 141, one end of the material inlet channel 150 is opposite to the conveying turntable 111, and the inner diameter of the material inlet channel 150 gradually decreases from the material inlet 141 to the conveying turntable 111.

[0101] In addition, in some embodiments, referring to Figs. 2 and 3, the conveying disc 111 can have a curved surface on the side for receiving the material, and the thickness of the conveying disc 111 can gradually decrease from the center of the conveying disc 111 to the outer edge of the conveying disc 111. In this way, the conveying disc 111 has a butterfly disc shape, and when the material is dispersed, the light and thin material is more likely to form a gap between the butterfly disc and the upper surface of the conveying disc 111, so as to be blown away by the airflow blown by the first blowing mechanism 120.

[0102] In the embodiments of the present application, the feeding device 100 further comprises a discharge chute 160, wherein, referring to Figs. 1 to 3, the discharge chute 160 has a discharge port 142, and the discharge port 142 is connected to the end of the second conveying mechanism 130 away from the conveying disc 111, and the bottom of the discharge chute 160 is lower than the upper surface of the second conveying mechanism 130.

[0103] Fig. 4 is a side view of another feeding device 100 provided by the embodiments of the present application.

[0104] As shown in Fig. 4, in the embodiments of the present application, the second conveying mechanism 130 can comprise a first bearing area 133, wherein the first bearing area 133 can comprise a turbulence area 1331 and a sink area 1332, one end of the turbulence area 1331 is connected to the conveying disc 111, the other end of the turbulence area 1331 is connected to one end of the sink area 1332, and the other end of the sink area 1332 is used to convey the material to the discharge port 142 of the feeding device 100 along the second direction L2.

[0105] It should be noted here that when the cover 140 is provided with the air port 143, the first bearing area 133 of the second conveying mechanism 130 can only be provided with the turbulence area 1331 at the feeding end.

[0106] In combination with Figs. 2 and 4, when the first bearing area 133 is only provided with the turbulence area 1331, the length of the first bearing area 133 is a first length H1, and when the first bearing area 133 is provided with the turbulence area 1331 and the sink area 1332, the length of the first bearing area 133 is a second length H2, and H2 is greater than H1.

[0107] Alternatively, in some embodiments, the turbulence area 1331 and the sink area 1332 can always exist, and the extension of the first bearing area 133 can be to lengthen the turbulence area 1331, so that the material is naturally stabilized and enters the sink state, and therefore, the setting of the air port 143 can shorten the length of the turbulence area 1331, so that the material is quickly stabilized. Therefore, the setting of the air port can shorten the overall length of the device.

[0109] As shown in Fig. 5, the present application also provides a material conveying device, which specifically can include the material distributing device 200 (see Figs. 6 and 7) and the above-mentioned feeding device 100. The material distributing device 200 is used to receive the material conveyed from the second end 132 of the second conveying mechanism and to distribute the received material in a single layer.

[0110] In one possible implementation, one end of the material distributing device 200 corresponds to the second end 132 of the second conveying mechanism, and the other end of the material distributing device 200 extends along the second direction L2.

[0111] Referring to Figs. 6 and 7, in the present application, the material distributing device 200 can include a third conveying mechanism 210 and a second blowing mechanism 220. The third conveying mechanism 210 includes a second carrying area 212 provided with a plurality of apertures 213. The second carrying area 212 is used to convey the material, and the apertures 213 are used to form a negative pressure channel with a negative pressure source. A negative pressure airflow in the negative pressure channel is used to negatively adsorb the material on the second carrying area 212 that is in contact with the second carrying area 212.

[0112] Moreover, the third conveying structure is also connected to the discharge port 142 of the feeding device 100. In this way, the material that is not adsorbed on the third conveying structure can fall into the discharge port 142 of the feeding device 100.

[0113] The second blowing mechanism 220 is used to blow the material that is not adsorbed on the second carrying area 212 to separate from the second carrying area 212, so that the material on the second carrying area 212 is distributed in a single layer.

[0114] For example, as shown in Figs. 6 and 7, the material distributing device 200 includes the third conveying mechanism 210 and the second blowing mechanism 220. The third conveying mechanism 210 includes the second carrying area 212, which is used to convey the material and is provided with a plurality of apertures 213. One end of the apertures 213 is connected to a negative pressure source (not shown in the figure) through a negative pressure channel (not shown in the figure). The negative pressure source generates a negative pressure airflow in the negative pressure channel, which is used to negatively adsorb the material on the second carrying area 212 that is in contact with the surface of the second carrying area 212. It should be noted that the negative pressure source mentioned in the present application can be a vacuum pump, and the negative pressure source can be arranged below the second carrying area 212 or on one side of the second carrying area 212.

[0115] It can be understood that the size of the negative pressure airflow generated by the negative pressure source is adjusted to control the size of the negative pressure adsorption force, so as to ensure that the material in contact with the surface of the second bearing area 212 is adsorbed on the second bearing area 212. The second blowing mechanism 220 blows the stacked material not adsorbed by the negative pressure adsorption force away from the second bearing area 212, so that the material on the second bearing area 212 is arranged in a single layer.

[0116] In the embodiment of the present application, the material distributing device 200 can further include an adsorption mechanism 230, the adsorption mechanism 230 is located below the second bearing area 212, one end of the adsorption mechanism 230 abuts against the second bearing area 212 and communicates with the pores 213, and the other end of the adsorption mechanism 230 is used to communicate with the negative pressure source, and a negative pressure channel is formed in the adsorption mechanism 230.

[0117] For example, as shown in FIG. 6, the adsorption mechanism 230 is located inside the third conveying mechanism 210, the adsorption mechanism 230 is located below the second bearing area 212 of the third conveying mechanism 210, one end of the adsorption mechanism 230 abuts against the second bearing area 212, and the adsorption mechanism 230 communicates with the pores 213 on the second bearing area 212. The other end of the adsorption mechanism 230 communicates with the negative pressure source, the negative pressure airflow generated by the negative pressure source passes through the negative pressure channel formed by the adsorption mechanism 230, and finally reaches the pores 213 of the second bearing area 212, so as to adsorb the material on the second bearing area 212 in contact with the surface of the second bearing area 212 by negative pressure. It can be understood that the second bearing area 212 is used to contact the surface of the material.

[0118] In the embodiment of the present application, the adsorption mechanism 230 includes a plurality of suction nozzles 231 and a pipeline 232, the plurality of suction nozzles 231 are connected to one end of the pipeline 232, the plurality of suction nozzles 231 are arranged at intervals below the second bearing area 212, and the other end of the pipeline 232 is connected to the negative pressure source.

[0119] In the embodiment of the present application, the second blowing mechanism 220 includes at least one first air knife 221, but is not limited to one first air knife 221, and can be any number, for example, two, three or four. The embodiment of the present application takes three first air knives 221 as an example, as shown in FIG. 6. Each first air knife 221 is provided with a first blowing nozzle 222 at one end, and the other end of each first air knife 221 is used to communicate with the gas source. A plurality of first air knives 221 are arranged at intervals along the conveying direction of the third conveying mechanism 210, and the first air knife 221 is used to form a first airflow to blow the material on the second bearing area 212.

[0120] The second carrying area 212 includes an inlet end 214 and an outlet end 215 along the conveying direction of the third conveying mechanism 210, and the part of the first air knives 221 is located above the second carrying area 212 and close to the outlet end 215. That is, as shown in FIG. 7, the second carrying area 212 includes an inlet end 214 and an outlet end 215, the inlet end 214 is used to send the stacked materials into the second carrying area 212, and the outlet end 215 is used to send the single-layer materials out of the second carrying area 212. The part of the first air knives 221 is located above the second carrying area 212 and close to the outlet end 215, which ensures that the materials about to leave the second carrying area 212 at the outlet end 215 are single-layer materials, thereby improving the conveying efficiency of the single-layer materials.

[0121] In the embodiment of the present application, the distance between each adjacent two first blowing nozzles 222 is d, and the size of the material is a along the conveying direction of the third conveying mechanism 210, and d>a, that is, the distance between each adjacent two first blowing nozzles 222 is greater than the size of the material.

[0122] It can be understood that the distance between each adjacent two first blowing nozzles 222 is greater than the size of the material, which can make the materials not adsorbed by the negative pressure in the conveying process be blown away to the second carrying area 212 by the first air flow of each first blowing nozzle 222, thereby preventing the same material from being swept by the first air flow generated by two or more first air knives 221 at the same time. It prevents the first air flow generated by the previous air knife (the last first air knife 221 close to the inlet end 214) from becoming a downward pressure, which causes the materials on the second carrying area 212 to stack.

[0123] In the embodiment of the present application, the second blowing mechanism 220 further includes at least one second air knife 223, but is not limited to one second air knife 223, and can be any number of two, for example, two. The embodiment of the present application specifically takes one second air knife 223 as an example, as shown in FIG. 7. The second air knife 223 is located at the side of the second carrying area 212. The second air knife 223 is used to form a second air flow to sweep the materials on the second carrying area 212 from the side.

[0124] As shown in FIG. 7, in the embodiment of the present application, one end of the second air knife 223 is connected with the second blowing nozzle 224, and the other end of the second air knife 223 is connected with a gas source (not shown in the figure). The gas source generates an air flow, the air flow passes through the second air knife 223 to form a second air flow, and the second air flow is sprayed out through the second blowing nozzle 224 to sweep the stacked materials on the second carrying area 212 away from the outlet end 215. The second air flow sprayed out from the second blowing nozzle 224 blows the materials on the second carrying area 212 not adsorbed by the suction nozzle 231 away from the surface of the second carrying area 212.

[0125] Please continue to refer to FIG. 7, as shown in FIG. 7, in the embodiment of the present application, the distributing device 200 can further be provided with a recycling structure 240. The recycling structure 240 is arranged close to the third conveying mechanism 210, and is used to recycle the material separated from the third conveying mechanism 210 and convey the recycled material to the feeding end of the third conveying mechanism 210 or the material inlet 141 of the feeding device 100. The recycling structure 240 is used to collect the material separated from the second bearing area 212 by the second air flow, so as to avoid the scattering and waste of the material and reduce the loss of the material.

[0126] In the embodiment of the present application, the third conveying mechanism 210 comprises a motor (not shown in the figure) and a transmission belt 211, wherein the motor is used to drive the transmission belt 211 to move. The transmission belt 211 is used to bear part of the material as the second bearing area 212, and the transmission belt 211 is provided with apertures 213.

[0127] It can be understood that the area of the transmission belt 211 used to bear the material is the second bearing area 212, that is to say, the second bearing area 212 is part of the transmission belt 211. And with the movement of the transmission belt 211 along the transmission direction, the specific position of the second bearing area 212 will change accordingly. It should be noted that the transmission belt 211 can be a rubber transmission belt 211, and can also be a metal transmission belt 211, but is not limited to the above two, for example, can also be a plastic transmission belt 211, etc.

[0128] In addition, in some embodiments, as shown in FIG. 8, the third conveying mechanism 210 can be an extension of the second conveying mechanism 130 of the feeding device 100, for example, part of the second conveying mechanism 130 can be used as the third conveying mechanism 210, and the third conveying mechanism 210 and the second conveying mechanism 130 can be one conveying structure, that is, the feeding device 100 and the distributing device 200 share one conveying mechanism.

[0129] Alternatively, in some other embodiments, as shown in FIG. 5, the third conveying mechanism 210 can be arranged downstream of the second conveying mechanism 130 of the feeding device 100, and the material can enter the feeding end of the third conveying mechanism 210 through the discharging end of the second conveying mechanism 130. At this time, the discharging end of the second conveying mechanism 130 and the feeding end of the third conveying mechanism 210 are connected, that is to say, the third conveying mechanism 210 and the second conveying mechanism 130 are two independent conveying mechanisms.

[0133] The first direction L1 is opposite to the direction of the linear speed of the conveying turntable 111 in the rotation process, and the first direction L1 and the second direction L2 are in the same direction.

[0144] In addition, after S205, the conveying method can further include:

In this way, when the material is fed into the feeding device 100 through the inlet 141, the material is dispersed by the rotation of the conveying turntable 111. Since the first blowing mechanism 120 is arranged above the conveying turntable 111, the blowing direction of the first blowing mechanism 120 is opposite to the linear velocity direction of the conveying turntable 111, the first blowing mechanism 120 can strip the uppermost layer of the material, the second conveying mechanism 130 can receive the material separated from the conveying turntable 111 and convey the material along the second direction L2, so that uniform and continuous thin layer feeding can be realized, and the technical problems of stacking feeding in the related art can be avoided or solved.
