[0038] The following description is used to fully explain the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0039] See also Figure 1-3 The present invention provides a technical solution: a feeding mechanism, comprising:

[0040] A support frame 100 and a hopper frame 200, wherein the hopper frame 200 is movably connected to the support frame 100, the hopper frame 200 is configured to be movable in a vertical direction, and the hopper frame 200 is configured to be rotated around one of the straight lines in the horizontal direction, and a dumping opening 200a communicating with the inside and outside is provided on the hopper frame 200, and a hopper stopper 201 is provided inwardly extending from the dumping opening 200a;

[0041] The hopper frame 200 has at least two working states, namely, an assembly state and a dumping state. When the hopper frame 200 is in the assembly state, the hopper frame 200 is located at the lower part of the support frame 100, and the dumping opening 200a faces upward. When the hopper frame 200 is in the dumping state, the hopper frame 200 is located at the upper part of the support frame 100, and the dumping opening 200a faces downward.

[0042] The horizontal dimension of the hopper frame 200 in the tilted state is much smaller than the vertical dimension of the feeding mechanism.

[0043] By filling materials into the hopper frame 200 in the assembled state and controlling the hopper frame 200 to switch from the assembled state to the dumping state, the lifting and dumping of the materials in the hopper frame 200 are achieved, and the horizontal size of the hopper frame 200 in the dumping state is further limited, so that the feeding mechanism can realize feeding in a limited horizontal space.

[0044] In order to further reduce the occupation of the feeding mechanism in the limited horizontal space, in the horizontal direction, the hopper frame 200 in the assembled state does not exceed the support frame 100.

[0045] In one embodiment, in the horizontal direction, the pouring opening 200 a of the hopper frame 200 in the assembled state and the pouring opening 200 a of the hopper frame 200 in the poured state are arranged at intervals.

[0046] Furthermore, the feeding mechanism also includes:

[0047] A driving member 300, wherein the driving member 300 is connected to the support frame 100, and a mounting plate 101 movable in a vertical direction is provided on the support frame 100, and the driving member 300 is drivingly connected to the mounting plate 101, and the mounting plate 101 is rotatably connected to the hopper frame 200 via a connecting shaft 102;

[0048] A guide member 400, wherein the guide member 400 is connected to the support frame 100, and the guide member 400 is located on one side of the movable path of the hopper frame 200 in the horizontal direction;

[0049] The flip track 500 is connected to the hopper frame 200, and the flip track 500 matches the guide member 400. The guide member 400 is configured to squeeze the inner wall of the flip track 500 to drive the hopper frame 200 to rotate through the connecting shaft 102. Through the above design, the feeding mechanism can realize the flipping of the hopper frame 200 by only setting a driving member 300 that drives the hopper frame 200 to move in the vertical direction, reducing the number of driving members 300 in the feeding mechanism, avoiding the problem of complex structure of the prior art, and facilitating popularization and application. The angle and length of the flip track 500 determine the flipping angle of the dumping opening 200a when the hopper frame 200 is in the dumping state.

[0050] In one embodiment, see Figure 4 The pouring opening 200a includes a pouring side 200a1 and an emptying side 200a2 opposite to each other. When the hopper frame 200 is in a pouring state, the pouring side 200a1 is located at the bottom of the hopper frame 200;

[0051] One end of the flip track 500 in the length direction is connected to the hopper frame 200, and the other end of the flip track 500 in the length direction is provided with an entrance port 501 connecting the inside and the outside, and the entrance port 501 is located on the side of the dumping side 200a1 away from the emptying side 200a2. When the hopper frame 200 is in an assembled state, the entrance port 501 is set toward the guide member 400, and a first baffle 502 extending upward is provided on the side of the entrance port 501 close to the hopper frame 200, and second baffles 503 are respectively provided on both sides of the flip track 500 in the direction of the connection line between the dumping side 200a1 and the emptying side 200a2, and the second baffle 503 is an inclined second baffle 503. When in use, the initial state of the hopper frame 200 is the loading state, and the driving member 300 drives the hopper frame 200 to rise, wherein the guide member 400 enters the flip track 500 through the entrance 501, and the guide member 400 squeezes the inner side of the second baffle 503 located below. Under the action of the tilted second baffle 503, the hopper frame 200 rotates on the mounting plate 101 through the connecting shaft 102, and the hopper frame 200 flips toward the dumping side 200a1, and the hopper frame 200 continues to rise. The flip track 500 is inverted after the hopper frame 200 flips and approaches the horizontal, and the second baffle 503 and the first baffle 502 located above are supported on the guide member 400 until the hopper frame 200 stops in the dumping state. It should be noted that a restraint member is provided between the hopper frame 200 and the mounting plate 101 to keep the dumping opening 200a on the material opening frame upward when the hopper frame 200 is in the non-dumping state.

[0052] To ensure accurate positioning of the hopper frame 200, continue to refer to Figure 1-3 Further, the feeding mechanism also includes: a proximity switch 900 and a positioning plate 600, the proximity switch 900 controls the connection of the driving member 300, the proximity switch 900 includes an upper switch and a lower switch, the upper switch and the lower switch are respectively arranged at the upper part and the lower part of the support frame 100, the positioning plate 600 is connected to the hopper frame 200, when the hopper frame 200 is in a dumping state, the positioning plate 600 corresponds to the upper switch, when the hopper frame 200 is in a loading state, the positioning plate 600 corresponds to the lower switch. When in use, two proximity switches 900 are arranged on the upper and lower parts of the support frame 100 to cooperate with the reduction motor to realize the automatic start and stop of the feeding mechanism. Furthermore, the proximity switch 900 is connected to the support frame 100 via a mounting frame 700, and the proximity switch 900 is configured to be suitable for adjusting the installation height via the mounting frame 700 to meet the lifting and flipping requirements of different equipment. Specifically, the mounting frame 700 and the support frame 100 are fixedly connected, and a plurality of mounting holes arranged in a vertical direction are opened on the mounting member.

The movable shaft 402 and the flip track 500 are slidably matched. The movable shaft 402 is supported by the fixed shaft 401. When the movable shaft 402 enters the inside of the flip track 500 and guides the hopper frame 200 by squeezing the inner wall of the flip track 500, the movable shaft 402 can rotate at the end of the fixed shaft 401 at the same time, converting the sliding friction between the movable shaft 402 and the flip track 500 into rolling friction, thereby reducing the resistance between the guide member 400 and the flip guide rail, and ensuring the smooth flipping of the hopper frame 200.

[0054] For further information, see Figure 2, in the vertical direction, the position of the guide member 400 on the support frame 100 is adjustable. Specifically, the guide member 400 also includes an adjustment plate, the adjustment plate is fixedly connected to the support frame 100, and the adjustment plate is provided with a plurality of adjustment holes arranged in sequence along the vertical direction, and the fixed shaft 401 is detachably connected to the adjustment hole through a connecting member. Optionally, the connecting member is a bolt. When in use, the fixed shaft 401 can be installed in different adjustment holes through a connecting member according to the lifting height requirements of the material, so as to adjust the installation height of the fixed shaft 401 and the movable shaft 402, and then adjust the flipping position of the hopper frame 200 in the vertical direction. The height adjustment method of the guide member 400 on the adjustment plate is the same as the height adjustment method of the proximity switch 900 on the mounting frame 700, and the two cooperate to adjust synchronously.

[0055] The support and the hopper frame 200 both adopt a frame structure, which effectively reduces weight to ensure the feasibility and convenience of single-person operation of the equipment, reduces the physical labor of workers and reduces labor costs.

[0056] In summary, the feeding mechanism has a simple structure. The driving member 300 cooperates with the guide member 400 and the turning guide rail to realize the lifting and tilting of the hopper, and continuously completes the lifting, unloading and falling actions, which effectively improves the feeding efficiency. Compared with the existing feeding equipment with complex structure, the feeding mechanism has a low manufacturing cost and is conducive to large-scale promotion and application.

In the process of pushing the hopper into the interior of the hopper frame 200 through the inlet and outlet 100b1, the guide rollers 204 guide and support the bottom of the hopper.

[0067] In order to prevent the hopper in the hopper frame 200 from overturning and causing the hopper to fall, further, the hopper stopper 201 is a cylindrical hopper stopper 201, and the number of the hopper stopper 201 is multiple, and the hopper stopper 201 is arranged at intervals in the direction of the line connecting the pouring side 200a1 and the emptying side 200a2.
