[0048] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that elements, structures, and features in one embodiment may also be beneficially combined in other embodiments without further description.

[0049] In the description of the present invention, it should be noted that the terms "inside", "outside", "upper", "lower", "front", "rear", "first", "second", etc., indicating directions or positional relationships, are based on the positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0050] In the description of this application, "install", "connect", "connect", "fix" and the like should be understood in a broad sense. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or a connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] The technical solution in the embodiment of the present application is to solve the technical problem that the feeding tray still needs to be manually unloaded in the above-mentioned prior art. The overall idea is as follows:

[0052] The present invention designs a feeding device, wherein a first carrier 310 and a second carrier 320 for placing materials are rotatably connected to a first support arm 220 and a second support arm 230 respectively. At the same time, one end of an adjusting component 4 is rotatably mounted on the mounting component 210, and the other end of the adjusting component 4 extends to the bottom of the first carrier 310, so that by rotating the adjusting component 4, this end can be made to abut against the lower end surface of the first carrier 310, so that the first carrier 310 rotates downward. In other words, by rotating the adjusting component 4, the first carrier 310 rotates downward along the horizontal axis direction. Since the first carrier 310 and the second carrier 320 are fixedly connected, when the first carrier 310 rotates downward under the action of the adjusting component 4, the second carrier 320 is driven to rotate downward at the same time, so that the bearing end surface formed by the first carrier 310 and the second carrier 320 tilts downward, so that the material rotates downward along the bearing end surface under the action of inertia, so that the material is unloaded. By adopting this structure, the material can be unloaded by simply rotating the adjusting component 4 without manual handling. This solves the technical problem in the prior art that the feeding tray still needs to be unloaded manually.

[0053] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0054] A feeding device comprises a shell 1, a supporting frame 2, a bearing member 3 and an adjusting component 4.

[0055] like Figure 1-2 As shown, the housing 1 includes four end faces, which are the first end face 110 and the fourth end face 140 arranged oppositely, and the second end face 120 and the third end face 130 arranged oppositely. In this embodiment, the first end face 110 is the rear end face, and the fourth end face 140 is the front end face; the second end face 120 and the third end face 130 are both side end faces, and the four end faces are connected to each other to form the housing 1. At the same time, the two ends at the upper edge of the fourth end face 140 are rotatably connected to the second end face 120 and the third end face 130 respectively; and the lower edge end of the fourth end face 140 is a movable part; under the action of external force, the fourth end face 140 can rotate up and down along the horizontal axis. Specifically, a rotating rod is arranged between the second end face 120 and the third end face 130. One end of the rotating rod is fixedly connected to the second end face 120, and the other end is fixedly connected to the third end face 130, and the fourth end face 140 is rotatably mounted on the rotating rod. And the housing 1 is covered on the outside of the support frame 2.

[0056] The support frame 2 includes a mounting member 210, a first support arm 220, and a second support arm 230. In this embodiment, the mounting member 210 is a long rod structure, and its length can be designed according to actual needs. The first support arm 220 and the second support arm 230 are long rod structures with the same structure, which are respectively arranged at the two ends of the mounting member 210, and the extension directions of the two support arms are consistent, and their extension directions are perpendicular to the length of the mounting member 210. At the same time, an auxiliary support member 240 is arranged between the first support arm 220 and the second support arm 230, one end of which is fixedly connected to the first support arm 220, and the other end of which is fixedly connected to the second support arm 230, and the auxiliary support member 240 is arranged in parallel with the mounting member 210, and there is a certain distance between the auxiliary support member 240 and the mounting member 210. At the same time, a handle 8 is arranged on the mounting member 210, which is convenient for the staff to control the conveying device during the transportation of materials.

[0057] The bearing member 3, in this embodiment, includes a first bearing member 310 and a second bearing member 320, and is preferably a plate-shaped structure. Specifically, the first bearing member 310 is located between the first support arm 220 and the second support arm 230; and flanges 311 are provided at both ends of the first bearing member 310, and the two flanges 311 are respectively overlapped on the first support arm 220 and the second support arm 230, that is, the two flanges 311 are not fixed on the first support arm 220 and the second support arm 230. At the same time, the end of the first bearing member 310 close to the mounting member 210 is symmetrically provided with a counterweight member 9, which is used to balance the stability of the bearing member during the storage of materials or rotation. The second bearing member 320 is located between the first supporting arm 220 and the second supporting arm 230; and the second bearing member 320 is fixedly connected to the lower edge of the first bearing member 310; and the connection between the first bearing member 310 and the second bearing member 320 forms a connection end; one end of the connection end is rotatably connected to the first supporting arm 220, and the other end is rotatably connected to the second supporting arm 230. In this embodiment, the first bearing member 310 and the second bearing member 320 are an integral structure, and form a bearing surface for carrying materials. At the same time, a first rotating shaft 330 is provided between the first supporting arm 220 and the second supporting arm 230, that is, one end of the first rotating shaft 330 is fixed to the first supporting arm 220, and the other end thereof is fixed to the second supporting arm 230. At the same time, the connection end between the first bearing member 310 and the second bearing member 320 is rotatably mounted on the first rotating shaft 330. Specifically, a plurality of mounting blocks are evenly arranged on the lower surface of the connection end, and the mounting blocks are rotatably connected to the first connecting shaft, thereby enabling the first supporting member 310 and the second supporting member 320 to be rotatably connected to the first rotating shaft 330 through the mounting blocks, and to be able to rotate up and down along the rotating axis.

[0058] like Figure 2-5As shown, in order to make the fourth end face 140 of the housing 1 rotate synchronously and stably with the bearing member 3, in this example, a first connecting member 5 and a second connecting member 6 with the same structure are also provided. Specifically, the first connecting member 5 includes a first connecting portion 520 and two first fixing portions 510 arranged oppositely, wherein one first fixing portion 510 is fixed on the first bearing member 310, and the other first fixing portion 510 is arranged on the fourth end face 140 of the housing 1; the two ends of the first connecting portion 520 are respectively rotatably connected with the two fixing portions. The second connecting member 6 includes a second connecting portion 620 and two second fixing portions 610 arranged oppositely, wherein one second fixing portion 610 is fixed on the first bearing member 310, and the other second fixing portion 610 is arranged on the fourth end face 140 of the housing 1; the two ends of the second connecting portion 620 are respectively rotatably connected with the two second fixing portions 610. By adopting the above structure, the fourth end face 140 of the housing 1 can rotate synchronously and in the same direction with the bearing member 3, so that the material can be unloaded more easily.

[0059] An adjusting component 4, one end of which is rotatably disposed on the mounting member 210; the other end of which extends to the bottom of the first supporting member 310; and by rotating the adjusting component 4, this end of the adjusting member 430 can be made to abut against the lower end surface of the first supporting member 310, so that the first supporting member 310 and the second supporting member 320 rotate and tilt downward at the same time, so that the material is unloaded.

[0060] Specifically, the adjustment component 4 includes a rotating member, an adjustment member 430 , and a holding member 440 .

[0061] In this embodiment, the gripping member 440 is in a strip structure, which is convenient for the staff to hold and adjust the rotating member more conveniently. One end of the rotating member is rotatably disposed on the mounting member 210 and fixedly connected to the gripping member 440; the other end thereof extends below the first bearing member 310.

[0062] Specifically, the lower end surfaces of the mounting member 210 and the auxiliary support member 240 are both provided with fixing members 250, and the two fixing members 250 are respectively located at the center of the mounting member 210 and the auxiliary support member 240, and the two fixing members 250 are provided with through holes, and the centerline axes of the two through holes coincide with each other. The rotating member includes a second rotating shaft 410 and a third rotating shaft 420, and the second rotating shaft 410 is a hollow structure, and its two ends are respectively fixedly sleeved in the two through holes.

[0063] At the same time, the third rotating shaft 420 is rotatably sleeved in the cavity of the second rotating shaft 410, and one end of the third rotating shaft 420 passes through the through hole set on the fixing member 250 on the mounting member 210, and passes through the first end face 110 of the shell 1 and is fixedly connected to the holding member 440, and the other end passes through the through hole set on the fixing member 250 on the auxiliary support member 240, and is fixedly connected to the adjusting member 430.

[0064] Continue to refer to Figure 4-5 , an arc-shaped rotation guide groove 411 is provided on the second rotation shaft 410, and the structure of the rotation guide groove 411 can be set according to the actual rotation angle required. And a rotation guide member 421 is provided on the third rotation shaft 420, and the rotation guide member 421 is arranged opposite to the rotation guide groove 411, and the rotation guide groove 411 is slidably arranged in the rotation guide groove 411, and can slide back and forth along the arc of the rotation guide groove 411. At the same time, a locking member 260 is also provided on the mounting member 210. Specifically, the locking member 260 includes a first end and a second end. The first end is slidably arranged on the upper end surface of the mounting member, and the second end thereof extends to the third rotation shaft 420. A threaded hole is provided at the second end of the locking member 260, and a thread is provided at one end of the third rotation shaft 420, so that the locking member 260 is threadedly connected to the third rotation shaft. At the same time, the third rotation shaft 420 passes through this threaded hole and is connected to the gripping member 440. Since the locking member 260 is threadedly connected to the third rotating shaft 420, a screw nut substructure is formed. Through this structure, the rotation of the third rotating shaft 420 can be converted into a linear motion of the locking member 260, that is, as the third rotating shaft 420 rotates, the locking member 260 can move back and forth along the axis direction of the third rotating shaft 420. Therefore, under the guidance of the rotation guide groove 411 and the rotation guide member 421, when the holding member 440 is rotated, the third rotating shaft 420 will drive the locking member 260 to move forward and backward along the axis direction of the rotating shaft. Therefore, when the unloading is completed, the holding member 440 is rotated, so that the third rotating shaft 420 drives the locking member 260 to move close to the carrier 3, and the locking member is stuck at the upper end surface of the carrier 3, that is, the locking member 260 blocks the carrier 3, limiting the downward rotation of the carrier 3. This has a locking effect on the carrier 3, making the carrier 3 more stable when containing materials. When unloading is required, the gripping member 440 is rotated so that the third rotating shaft 420 drives the locking member 260 to move away from the supporting member 3, that is, the locking member 260 and the supporting member 3 are in a separated state, thereby releasing the locking member 260 from the supporting member 3, allowing the supporting member 3 to rotate freely.

[0065] Furthermore, the adjusting member 430 is vertically arranged on the third rotating shaft 420, that is, one end of the adjusting member 430 is fixed on the third rotating shaft 420, and the other end thereof extends along the axial direction perpendicular to the third rotating shaft 420. The adjusting member 430 is located below the first bearing member 310 and has a certain distance from the first rotating shaft 330. When the third rotating shaft 420 is rotated, the adjusting member 430 is rotated toward the first bearing member 310, and can push the first bearing member 310 to rotate downward, so that the entire bearing member 3 tilts downward, so that the material moves downward under the action of inertia, thereby allowing the material to be unloaded.

[0066] In order to further limit the rotation angle of the support member 3, a limiter 10 is further provided. Specifically, one end of the limiter 10 is fixed to the first support arm 220, and the other end thereof is fixed to the second support arm 230. The limiter 10 is provided corresponding to the first rotation axis 330 and is located below the first rotation axis 330. By providing this structure, it is possible to prevent the support member 3 from rotating too much during the adjustment process, causing the material to fall too fast and thus be damaged.

[0067] like Figure 6 As shown, a magnetic component 7 is also provided on one side of the adjusting member 430, and the magnetic component 7 includes a magnetic base 710 and a strong magnetic magnet 720. The magnetic base 710 is located on one side of the adjusting member 430 and is installed on the limit member 10. The strong magnetic magnet 720 is two pieces and is fixedly provided on the magnetic base 710. When the adjusting member 430 is rotated to a horizontal position, the adjusting member 430 can contact the strong magnetic magnet 720. In this embodiment, the adjusting member 430 is a metal structure. After unloading, the staff only needs to release the gripping member 440. The adjusting member 430 can be automatically attracted to the magnet under the action of the strong magnetism, so that the bearing member 3 is restored to the initial state.

[0068] Through the cooperation among the above support frame 2, the bearing member 3, and the adjustment assembly 4, when the material is being transported, due to the absence of external force, the bearing member 3 can be overlapped on the two support arms through the flange 311 structure, so that the bearing member 3 is in a horizontal state and can be used to place the material. When the material needs to be unloaded, the adjustment member 430 is rotated to the bottom of the first bearing member 310 by rotating the gripping member 440, and the bearing member 3 is rotated downward under the action of the adjustment member 430, that is, the bearing end face is tilted downward, so that the material is automatically unloaded without manual handling and unloading, which solves the technical problem that the feeding tray still needs manual unloading in the prior art.

[0069] In order to explain this application more clearly, Figures 1 to 6 The working principle of the present invention is further described by taking the embodiment shown as an example:

[0070] When the material is transported to the unloading place through this feeding device, the staff rotates the adjustment component 4, that is, rotates the gripping member 440 to rotate the third rotating shaft 420. Under the rotation of the third rotating shaft 420, the adjustment member 430 is rotated to the first bearing member 310, and the upper end of the first bearing member 310 is lifted, so that the entire bearing member 3 rotates downward, thereby forming a downwardly inclined bearing end surface, so that the material moves downward under the action of inertia, and the unloading work is completed. When the unloading is completed, the staff only needs to loosen the gripping part, and under the action of the magnetic component 7, the adjustment member 430 is rotated to the magnetic component 7 and is in a horizontal state. In this way, the bearing member 3 is rotated to a horizontal position, that is, the feeding device is restored to its initial state. Therefore, through the above structure, unloading can be completed without manual handling, which solves the technical problem that the feeding tray still needs to be manually unloaded in the prior art, reduces human labor, effectively improves production efficiency, and reduces production costs.
