DETAILED DESCRIPTION

[0023] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0025] In the present application, unless otherwise stated, the orientation words such as "up, down, top, bottom" are generally directed to the direction shown in the drawings, or are directed to the vertical, perpendicular or gravity direction of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer relative to the contour of each component itself, but the above-mentioned orientation words are not used to limit the present application.

[0026] Referring to Figure 1 and Figure 2 , the feeder includes a housing 10, a first sieve plate 20, a second sieve plate 30 and a dust extraction assembly 90, the housing 10 has a feeding channel 13 for material conveying inside, the feeding channel 13 is provided with a feed inlet 11 and a discharge outlet 12 at both ends respectively, the first sieve plate 20 is arranged in the feeding channel 13, and the first sieve plate 20 is located below the feed inlet 11, along the material advancing direction, the second sieve plate 30 is located at one end of the first sieve plate 20 close to the discharge outlet 12, the second sieve plate 30 is coplanar with the bottom wall of the feeding channel 13, the dust extraction assembly 90 is arranged at the discharge end of the housing 10, and the dust extraction assembly 90 collects the dust at the discharge end of the housing 10.

[0027] In the process of material transportation, the material passes through the first sieve plate 20 to be screened for the first time to remove small pieces and powder; and then passes through the second sieve plate 30 to be screened again. By arranging the collecting assembly 40 below the second sieve plate 30, the small pieces and powder after screening can be collected to avoid direct discharge of the powder and improve the quality of the product. The dust extraction assembly 90 can suck the dust adhering to the surface of the material during the discharging process to further remove the dust in the material and improve the quality of the product.

[0028] In the present application, the feeder further comprises a baffle assembly 80 arranged at the discharging end of the housing 10. The baffle assembly 80 comprises a first baffle 81 connected to the bottom wall of the housing 10 and a second baffle 82 connected to the top wall of the housing 10. An opening downward discharging port 12 is formed between the first baffle 81 and the second baffle 82.

[0029] Since the material is transported in the feeding channel 13 by the electromagnetic drive or the vibration motor as a power source, some splashing will occur during the transportation process. When the material is still in the feeding channel 13, the splashing material will be blocked by the inner wall of the housing 10 and continue to stay in the feeding channel 13. When the material is transported to the outlet end of the feeding channel 13, the splashing material will be blocked by the baffle assembly 80 and finally discharged from the position of the discharging port 12. By arranging the baffle at the discharging end of the material, the splashing of the material during the discharging process is reduced, and the stability of the discharging is increased.

[0030] In the present application, a dust suction port 14 is arranged on the first baffle 81 or the second baffle 82. The dust extraction assembly 90 communicates with the dust suction port 14.

[0031] In the present application, the dust extraction assembly 90 comprises a dust extraction pipe communicating with the dust suction port 14 and a negative pressure assembly communicating with the dust extraction pipe and providing negative pressure for the dust extraction pipe.

[0032] By arranging the dust suction port 14 and the dust extraction assembly 90, the dust adhering to the surface of the material can be sucked during the discharging process of the material to further remove the dust in the material. The dust extraction assembly 90 comprises a dust extraction pipe and a negative pressure assembly. The discharging port 12 is connected to the negative pressure assembly through the dust extraction pipe. During the discharging process, the negative pressure assembly provides negative pressure for the dust suction port 14 to suck the dust adhering to the surface of the material, thereby achieving the cleaning of the material. The negative pressure assembly is preferably a fan.

[0033] In the present application, the feeder further comprises a collecting assembly 40 connected to the housing 10. At least part of the collecting assembly 40 is arranged below the second sieve plate 30 to collect the impurities passing through the second sieve plate 30.

[0034] Since the second sieve plate 30 is coplanar with the bottom wall of the feeding channel 13, the material will not collide with the second sieve plate 30 when passing through the second sieve plate 30, thereby avoiding the generation of additional broken material and dust. Through twice screening of the material, the broken material and powder with small size or weight in the material are removed, thereby improving the quality of the transported product.

[0035] During transportation, the material enters the feeding channel 13 from the feeding port 11 and is discharged from the discharging port 12. The movement of the material in the feeding channel 13 is powered by an electromagnetic driver or a vibration motor arranged outside the shell 10, so that the material moves from the feeding end of the feeding channel 13 to the discharging end of the feeding channel.

[0036] In the present application, the collecting assembly 40 includes a collecting cover 41 and a discharging member 42. The collecting cover 41 is connected with the shell 10, and at least part of the collecting cover 41 is located below the second sieve plate 30. The discharging member 42 is in communication with the collecting cover 41 and discharges the powder in the collecting cover 41.

[0037] The collecting cover 41 is a cover structure and can completely cover the second sieve plate 30. Thus, the broken material and powder screened by the second sieve plate 30 are completely located in the collecting cover 41. The discharging member 42 discharges the broken material in the collecting cover 41, thereby facilitating the collection of the broken material and powder in the collecting cover 41.

[0038] The discharging member 42 is preferably a discharging pipe. After the broken material enters the collecting cover 41, the broken material is discharged along the discharging pipe. In order to reduce the leakage of the powder, a collection bag is arranged at the end of the discharging pipe. The collection bag collects the broken material and powder, or the discharging member 42 directly selects the collection bag and is arranged at the discharging position of the collecting cover 41 to directly collect the broken material and powder in the collecting cover 41. In order to improve the collection efficiency of the discharging pipe for the broken material and powder, a negative pressure conveying device is arranged on the discharging pipe to provide negative pressure in the collecting cover 41, thereby reducing the residue of the broken material and powder in the collecting cover 41.

[0039] In the present application, a placing port is arranged on the shell 10, the second sieve plate 30 is arranged below the placing port, the collecting cover 41 is provided with a mounting structure 70, and the second sieve plate 30 abuts against the shell 10 through the mounting structure 70.

[0040] Specifically, the second screen plate 30 is placed at the position of the placement opening. When the material passes through the placement opening, the qualified material will pass through the second screen plate 30 and be discharged from the discharge opening 12, and the broken material and dust will be screened by the second screen plate 30 and fall into the collecting cover 41. The mounting cover is connected to the shell 10, which is used to collect the screened broken material and dust and support the installation of the second screen plate 30. The mounting structure 70 can be a pair of grooves arranged on a pair of opposite sides of the mounting cover. The two ends of the second screen plate 30 are respectively inserted into the two grooves, so as to fix the second screen plate 30. The mounting structure 70 can also be a support block. The bottom surface of the second screen plate 30 abuts against the support block, so as to support the second screen plate 30 and stably place the second screen plate 30 below the placement opening.

[0041] In the present application, the collecting assembly 40 further comprises an inspection cover 50 which is detachably mounted on one side of the collecting cover 41.

[0042] When the second screen plate 30 needs to be replaced or inspected, the inspection cover 50 is removed, and the second screen plate 30 is removed or inspected through the inspection opening. When the second screen plate 30 is normally used, the inspection cover 50 remains in the mounted state and does not affect the normal use of the second screen plate 30 and the transportation of the material in the feeding channel 13. The detachable installation of the inspection cover 50 facilitates the replacement or inspection of the second screen plate 30.

[0043] Referring to Figure 1 , the first screen plate 20 is inclinedly arranged. The first screen plate 20 and the shell 10 form a material collecting space 60. The first screen plate 20 separates the feeding channel 13 and the material collecting space 60.

[0044] Specifically, when the material enters the feeding channel 13 from the feeding opening, the material will directly fall on the first screen plate 20. Since the first screen plate 20 is inclinedly arranged, the material will slide along the inclinedly arranged first screen plate 20 into the feeding channel 13. In the process of sliding, the broken material and dust will fall into the material collecting space 60, and the qualified material will continue to move along the feeding channel 13. By incliningly arranging the first screen plate 20, the material can be conveniently screened, and the material collecting space 60 can be directly formed between the first screen plate 20 and the shell 10, thereby saving the use of the plate.

[0045] In the present application, a waste opening is formed in the shell 10. The waste opening is in communication with the material collecting space 60, and the waste opening is located at one end of the material collecting space 60 close to the discharge opening 12.

[0046] Specifically, the material in the feeding channel 13 is transported by an electromagnetic drive or a vibration motor, and the transportation direction is from the feeding end to the discharging end of the feeding channel 13. Since the material collecting space 60 is also arranged in the shell 10, the crushed material and the powder in the material collecting space 60 also move in the same direction in the material collecting space 60. The crushed material and the powder are concentrated at one end of the material collecting space 60 close to the discharge port 12. Therefore, the waste port is located at one end of the material collecting space 60 close to the discharge port 12, so that the crushed material and the powder in the material collecting space 60 can be easily discharged and collected.

[0047] In the present application, the feeding channel 13 also has a mounting structure 70 arranged on the inner wall of the shell 10. The mounting structure 70 mounts the first sieve plate 20. The mounting structure 70 includes: a limiting block, at least two limiting blocks are arranged on both sides of the first sieve plate 20, and at least part of the first sieve plate abuts against the two limiting blocks; or a slot, the slot is opened on the inner wall of the shell 10, and the first sieve plate is inserted into the slot.

[0048] Specifically, preferably, the mounting structure 70 is two groups arranged on one pair of opposite side walls of the shell 10, so as to better mount and fix the first sieve plate 20. When the mounting structure 70 is a limiting block, the first sieve plate 20 is clamped by the two limiting blocks at the same time. The end of the first sieve plate 20 close to the feeding channel 13 abuts against the bottom wall of the shell and cannot continue to move. The first sieve plate 20 and the shell form a triangular structure therebetween, thereby ensuring the stability of the mounting of the first sieve plate 20. When the mounting structure 70 is a slot, the side edge of the first sieve plate 20 is limited by the slot wall and cannot move, thereby ensuring the stability of the mounting of the first sieve plate 20. The first sieve plate 20 is supported by the mounting structure 70, thereby increasing the stability of the mounting of the first sieve plate 20 and facilitating the mounting and dismounting of the first sieve plate 20.

[0049] In one embodiment, the end of the shell away from the feeding end is detachably provided with an access plate. The access plate facilitates the mounting, dismounting and maintenance of the first sieve plate 20.

[0050] In the present application, a dust removal port 15 is opened on the shell 10. The dust removal port 15 is arranged at one end of the shell 10 close to the discharge port 12 and is located above the shell 10. The feeder further comprises a dust removal assembly 91 which communicates with the dust removal port 15.

[0051] Specifically, during the transportation of the material, a certain amount of dust will float above the material in the feeding channel 13. The dust removal assembly 91 collects the dust in the feeding channel 13, thereby reducing the emission of dust. The dust removal assembly 91 includes a dust removal cover and a negative pressure device. The negative pressure device provides negative pressure to collect the dust in the feeding channel 13, thereby further reducing the emission of dust into the environment.

[0052] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:

[0053] 1. In the process of material transportation, the material will pass through the first sieve plate 20 for the first time, and the small size or weight of the material and powder are screened out; then the material passes through the second sieve plate 30 for the second time. By setting the collecting assembly 40 under the second sieve plate 30, the collected material and powder can be collected, avoiding the direct discharge of the powder, collecting the material and improving the quality of the product. The dust extraction assembly 90 can adsorb the dust adhering to the surface of the material during the discharging process, further removing the dust in the material and improving the quality of the product.

[0054] 2. When the second sieve plate 30 needs to be replaced or repaired, the maintenance cover 50 is removed, the second sieve plate 30 is removed or the second sieve plate 30 is repaired through the maintenance opening, and when the second sieve plate 30 is normally used, the maintenance cover 50 remains installed, without affecting the normal use of the second sieve plate 30 and the transportation of the material in the feeding channel 13. The detachable installation of the maintenance cover 50 facilitates the replacement or repair of the second sieve plate 30.

[0055] 3. Since the material in the feeding channel 13 is transported by the electromagnetic drive or the vibration motor as a power source, a certain amount of splashing will occur during the transportation process. When the material is still in the feeding channel 13, the splashing material will be blocked by the inner wall of the shell 10 and continue to stay in the feeding channel 13. When the material is transported to the outlet end of the feeding channel 13, the splashing material will be blocked by the baffle assembly 80 and finally discharged from the discharge port 12. By setting the baffle at the discharge end of the material, the splashing of the material during the discharging process is reduced, and the stability of the discharging is increased.
