[0038] The following description is intended to fully illustrate the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

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

[0040] The support frame 100 and the hopper frame 200 are movably connected to the support frame 100. The hopper frame 200 is configured to be movable in the vertical direction and to be rotated about one of the straight lines in the horizontal direction. The hopper frame 200 is provided with a pouring opening 200a communicating with the inside and outside, and a hopper stopper 201 is provided inwardly extending from the pouring opening 200a.

[0041] The hopper frame 200 has at least two working states, namely an assembled state and a dumping state. When the hopper frame 200 is in the assembled 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 the hopper frame 200 in the assembled state with materials, the hopper frame 200 is controlled to switch from the assembled state to the dumping state, thereby realizing the lifting and dumping of the materials in the hopper frame 200, and further limiting the horizontal size of the hopper frame 200 in the dumping state, so that the feeding mechanism can realize feeding within 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 spaced apart.

[0046] Furthermore, the feeding mechanism further comprises:

[0047] A driving member 300 is connected to the support frame 100. The support frame 100 is provided with a mounting plate 101 that moves in a vertical direction. The driving member 300 is driven to connect to the mounting plate 101. The mounting plate 101 is rotatably connected to the hopper frame 200 via a connecting shaft 102.

[0048] A guide member 400, 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 via the connecting shaft 102. Through the above design, the feeding mechanism can achieve the flipping of the hopper frame 200 by only providing 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 in 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 501 connecting the inside and the outside, and the entrance 501 is located on the side of the dumping side 200a1 away from the emptying side 200a2. When the hopper frame 200 is in the assembled state, the entrance 501 is set toward the guide member 400, and the side of the entrance 501 close to the hopper frame 200 is provided with an upwardly extending first baffle 502, and the flip track 500 is respectively provided with second baffles 503 on both sides of the line connecting the dumping side 200a1 and the emptying side 200a2, and the second baffle 503 is an inclined second baffle 503. When in use, the hopper frame 200 is initially in a 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. The hopper frame 200 continues to rise, and the flip track 500 is inverted after the hopper frame 200 flips and approaches the horizontal level. 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 is provided between the hopper frame 200 and the mounting plate 101 to keep the dumping opening 200a on the material opening frame facing 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 Furthermore, the feeding mechanism also includes a proximity switch 900 and a positioning plate 600. The proximity switch 900 controls the connection to the driving member 300. The proximity switch 900 includes an upper switch and a lower switch, which are respectively arranged at the upper and lower portions 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. During use, the two proximity switches 900 arranged at the upper and lower portions of the support frame 100 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 through the mounting bracket 700. The proximity switch 900 is configured to be suitable for adjusting the installation height through the mounting bracket 700 to meet the lifting and flipping requirements of different equipment. Specifically, the mounting bracket 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 proximity switch 900 is connected to the corresponding mounting holes through a connecting member. Optionally, the connecting member is a bolt.

[0053] For further information, see Figure 4-5 The guide member 400 includes a fixed shaft 401 and a movable shaft 402. One end of the fixed shaft 401 is connected to the support frame 100, and the other end of the fixed shaft 401 is rotatably connected to the movable shaft 402. The movable shaft 402 and the flip track 500 are in sliding cooperation. The movable shaft 402 is supported by the fixed shaft 401. When the movable shaft 402 enters 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 simultaneously rotate at the end of the fixed shaft 401, 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, 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, which 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 the 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 are adjusted synchronously.

[0055] The bracket 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, reducing workers' physical labor and reducing labor costs.

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

[0057] By setting a proximity switch 900 to control the start and stop of the driving member 300, and setting the proximity switch 900 and the guide member 400 to be adjustable in the vertical direction, adaptation to hoppers of various sizes is achieved;

[0058] Many components are designed as frame structures to effectively reduce weight, ensuring the feasibility and convenience of single-person operation of the equipment, reducing workers' physical labor and labor costs;

[0059] The compactness of the loader structure is ensured while meeting the loading efficiency, solving the problem of limited available space in the complete production line.

[0060] Furthermore, the support frame 100 includes a base frame 103 and a column 104, the base frame 103 is arranged horizontally, and the column 104 is vertically installed above the base frame 103, and a transmission opening 1041 communicating with the inside and outside is opened on the column 104, and the transmission opening 1041 is arranged in the vertical direction. A mounting plate 101 is slidably connected in the transmission opening 1041, and the mounting plate 101 is rotatably connected to the hopper frame 200 through a connecting shaft 102. Preferably, the column 104 and the base frame 103 are connected by high-strength bolts;

[0061] The driving member 300 includes a reduction motor and a transmission chain. The reduction motor is arranged at the top of the column 104. The transmission chain is installed on the column 104 in the vertical direction. The reduction motor is driven to connect to the mounting plate 101 through the transmission chain. Preferably, the reduction motor and the column 104 are connected by bolts. Preferably, the driving member 300 adopts a variable frequency motor in combination with a reducer to meet different lifting speeds. Specifically, sprockets are installed on the output shaft of the reduction motor and the lower part of the inner side of the column 104. The transmission chain is installed between the two sprockets. The mounting plate 101 is fixed on the transmission chain. The reduction motor drives the transmission chain to reciprocate in the vertical direction through the sprocket, thereby realizing the rising and falling of the hopper frame 200.

[0062] To improve the dustproof effect of this mechanism, see Figure 2-3 Furthermore, a protective shell 105 is provided above the column 104. The protective shell 105 covers the outside of the reduction motor. The transmission chain is arranged inside the column 104. A dust baffle 106 is provided in the transmission opening 1041. The dust baffle 106 is fixedly connected to both sides of the transmission opening 1041 in the vertical direction. A gap is reserved between the dust baffle 106 and both sides of the transmission opening 1041 in the horizontal direction for the movement of the mounting plate 101. The dust baffle 106 and the protective shell 105 are provided to shield the reduction motor and the transmission chain from the outside world. At the same time, a gap is left between the dust baffle 106 and the inner wall of the transmission opening 1041 to ensure the passability of the mounting plate 101. Preferably, the protective shell 105 and the dust baffle 106 are connected by bolts, and the column 104 and the protective shell 105 are connected by bolts, which facilitates maintenance and transportation.

[0063] In order to facilitate the transfer of the feeding mechanism, further, handrail groups 107 are provided on both sides of the support frame 100 in the horizontal direction, and the support frame 100 is provided with relative equipment sides 100a and operating sides 100b. The hopper frame 200 is arranged on the support frame 100 in a manner close to the equipment side 100a. The bottom of the equipment side 100a of the support frame 100 is provided with fixed universal wheels 801 to ensure the stability of the support frame 100 while being as close to the Chinese herbal medicine equipment as possible. The bottom of the operating side 100b of the support frame 100 is bent upward and is provided with universal wheels 802 with brakes to ensure that the feeding mechanism is fixed after being moved into place.

[0064] Specifically, the base frame 103 is an I-shaped base frame 103, and the base frame 103 includes a first frame 1031 arranged relatively parallel on a horizontal plane, and a second frame 1032 vertically connected between adjacent first frames 1031. The first frame 1031 is connected to the column 104, and the four corners of the base frame 103 are respectively provided with a universal wheel. The armrest group 107 is provided with a first armrest and a second armrest. The first armrest is provided on the column 104, and the second armrest is provided above the second frame 1032. Preferably, a diagonal bracing structure is provided between the first frame 1031 and the column 104 to ensure the stability of the structure.

[0065] See also Figure 4 The hopper frame 200 is a semi-enclosed hopper frame 200. The pouring side 200a1 of the pouring opening 200a extends outward to form a material discharge bottom plate 202. Both sides of the pouring opening 200a adjacent to the pouring side 200a1 extend outward to form material discharge side plates 203. The cross-sectional dimensions of the material discharge bottom plate 202 and the material discharge side plates 203 gradually decrease as they move away from the pouring opening 200a. This forms a funnel-shaped guide structure outside the pouring opening 200a. This provides a certain degree of shielding for the material during pouring, preventing it from spilling and ensuring a uniform discharge position.

[0066] The operating side 100b of the hopper frame 200 is provided with an inlet and outlet 100b1, which is connected to the pouring opening 200a. A guide roller 204 is provided at the bottom of the hopper frame 200. The guide roller 204 is rotatably connected to the hopper frame 200, and the axis of the guide roller 204 is parallel to the inlet and outlet 100b1. There are multiple guide rollers 204, which are spaced apart and arranged in a manner away from the inlet and outlet 100b1. When the hopper is pushed into the hopper frame 200 through the inlet and outlet 100b1, the guide roller 204 guides and supports the bottom of the hopper.

[0067] To prevent the hopper in the hopper frame 200 from overturning and causing it to fall, the hopper stopper 201 is further provided in a cylindrical shape. There are multiple hopper stoppers 201, and the hopper stoppers 201 are spaced apart in the direction of the line connecting the pouring side 200a1 and the emptying side 200a2. In one embodiment, there are four hopper stoppers 201, with two hopper stoppers 201 provided at a position of the pouring opening 200a near the pouring side 200a1 and two at a position of the pouring opening 200a near the emptying side 200a2. During use, the hopper frame 200 is lifted into position and then overturned. The hopper stoppers 201 limit the position of the hopper in the hopper frame 200, ensuring that the hopper frame does not overturn and fall. Furthermore, the hopper limit member 201 is divided into two groups, and the number of the hopper limit members 201 in each group is multiple, wherein the hopper limit member 201 close to the pouring side 200a1 is the lower limit member 2011, and the hopper limit member 201 close to the emptying side 200a2 is the upper limit member 2012, and in the axial direction of the pouring opening 200a, the upper limit member 2012 is located on the outside of the lower limit member 2011. By limiting the relative positions of the upper limit member 2012 and the lower limit member 2011 in the axial direction of the pouring opening 200a, when the hopper frame 200 is in the assembled state, the upper limit member 2012 and the bottom of the hopper frame 200 have a larger space so that the hopper enters the interior of the hopper frame 200 through the inlet and outlet. At the same time, when the hopper frame 200 is in the pouring state, the material frame flips upside down, and the material frame further flips to the position of the upper limit member 2012 under the action of gravity and stops, thereby further increasing the flipping angle of the hopper to reduce material accumulation at the bottom of the hopper. At the same time, the cylindrical hopper limit member 201 also reduces the risk of material adhesion.

[0068] The hopper frame 200 is connected to the mounting plate 101 via the connecting shaft 102. Specifically, the connecting shaft 102 and the hopper frame 200 are fixedly connected by bolts. A connecting plate is provided between the connecting shaft 102 and the mounting plate 101 to fix a rolling ball bearing, wherein a shoulder is provided on the side of the connecting plate. A gasket is installed between the connecting shaft 102 and the connecting plate to reduce friction loss. The connecting shaft 102 passes through the hopper frame 200 on the side away from the connecting plate, and a sealing plate is provided to limit the hopper frame 200.

[0069] In one embodiment, the above-mentioned feeding mechanism is used for feeding Chinese herbal medicines in a confined space.

[0070] The feeding mechanism utilizes a reduction motor to drive a chain to cooperate with a guide mechanism, and realizes the adaptation with each size of the material frame through the positioning of a proximity switch, completes the lifting, discharging and falling actions, effectively improves the feeding efficiency of Chinese herbal medicines, and effectively reduces the weight through the frame structure arranged at multiple positions to ensure the feasibility and convenience of single-person operation of the equipment, reduces the physical labor of workers and the labor cost, ensures the compactness of the feeding machine structure under the premise of meeting the feeding efficiency, solves the problem of limited available space in the complete production line, and provides an effective solution for the Chinese herbal medicine feeding mode in the limited space.

[0071] In addition, the feeding mechanism is used in cooperation with the hopper frame, and the two can be separated, which avoids the problem that the Chinese herbal medicines are difficult to completely fall off after contacting with the feeding equipment due to the large viscosity after being soaked in water, is not convenient for equipment cleaning, and even causes mutual pollution between the medicinal materials.

[0072] The above-described embodiments are only used to illustrate the technical ideas and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and the present embodiment cannot be used to limit the patent application range of the present application, that is, any equivalent changes or modifications made according to the spirit disclosed in the present application still fall within the patent range of the present application.
