[0020] To at least partially resolve the above issues, please refer to Figs. 1 to 3 This application provides a grain mill 10, which includes a frame 100, a grinding component 200, and a clamping component 300.

[0021] The grinding assembly 200 is fixedly mounted on the frame 100, and has a feed inlet 211 and a discharge outlet 212 facing each other. The grinding assembly 200 is fixed to the top platform of the frame 100. The grinding cylinder 210 has a funnel-shaped feed inlet 211 at the top and a discharge outlet 212 at the bottom. A conical or cylindrical grinding roller 220 is installed inside the grinding cylinder 210, and the grinding roller 220 is driven to rotate at high speed by a motor through a belt drive mechanism. The operator can finely adjust the gap between the grinding roller 220 and the inner wall of the grinding cylinder 210 by using an adjusting handwheel (not shown) located on the side of the frame 100, thereby controlling the coarseness of the ground powder. A control valve (not shown) is usually also provided below the discharge outlet 212 to close the discharge outlet 212 when the packaging bag 20 is not in place.

[0022] The clamping assembly 300 is located on one side of the frame 100. The clamping assembly 300 includes a fixed frame 310, a first clamping mechanism 320 and a second clamping mechanism 330. The fixed frame 310 and the first clamping mechanism 320 are arranged side by side, and the first clamping mechanism 320 is located below the discharge port 212. The second clamping mechanism 330 is arranged opposite to the fixed frame 310 and spaced apart. The second clamping mechanism 330 is configured to clamp the packaging bag 20 located on the fixed frame 310 and move it to a position opposite to the first clamping mechanism 320, so as to cooperate with the first clamping mechanism 320 to clamp the opposite two sides of the packaging bag 20 respectively, so as to receive the powder flowing out of the discharge port 212.

[0023] The fixing frame 310 is located at the foremost end of the clamping assembly 300. It is a flat plate or a groove-shaped structure with side baffles, used for stacking unused packaging bags 20. Sensors (such as photoelectric sensors) can be installed on the fixing frame 310 to detect whether there are insufficient packaging bags 20. The first clamping mechanism 320 is located below the discharge port 212 and serves as a fixed support point on one side of the packaging bag 20. It is arranged side by side with the fixing frame 310.

[0024] The clamping assembly 300 is installed on one side of the frame 100 and mainly undertakes the automatic feeding and positioning functions of the packaging bag 20.

[0025] The fixing frame 310 is located at the foremost end of the clamping assembly 300 and is a flat plate or a groove-shaped structure with side baffles for stacking empty packaging bags 20. Sensors (such as photoelectric sensors) can be installed on the fixing frame 310 to detect whether there are insufficient packaging bags 20.

[0026] The first gripping mechanism 320 is located directly below the discharge port 212. The first guide rod 321 is vertically fixed to the frame 100. The first fixing plate 322 is L-shaped or plate-shaped, and its tail is provided with a sliding sleeve that fits onto the first guide rod 321. The first gripping component 323 is installed at the front end of the first fixing plate 322. In this embodiment, the first gripping component 323 is a corrugated vacuum suction cup, which is connected to a vacuum generator controlled by a solenoid valve through an air pipe. The first fixing plate 322 is provided with locking screws, which, after being tightened, can fix the first fixing plate 322 at any height position of the first guide rod 321, thereby adjusting the height of the suction cup to match packaging bags 20 of different specifications.

[0027] The second clamping mechanism 330 is located between the fixed frame 310 and the first clamping mechanism 320. Its structural principle is similar to that of the first clamping mechanism 320, including a second guide rod 331, a second fixed plate 332, and a second clamping component 333. The second clamping component 333 also adopts a vacuum suction cup, and the number corresponds to that of the first clamping component 323 (for example, two on each side, for a total of four suction cups).

[0028] The grain mill 10 provided in this application embodiment, by setting a second clamping mechanism 330 that is opposite to and spaced apart from the fixed frame 310, can clamp the packaging bag 20 located on the fixed frame 310 and move it to a position opposite to the first clamping mechanism 320 before the grinding assembly 200 starts working, so that the packaging bag 20 is located below the discharge port 212 of the grinding assembly 200. Under the combined action of the second clamping mechanism 330 and the first clamping mechanism 320, the opposite two sides of the packaging bag 20 are clamped respectively, so that the opening of the packaging bag 20 is fully opened to receive the powder flowing out of the discharge port 212, thereby realizing the automatic collection of powder, greatly improving the working efficiency of the grain mill 10, and also facilitating the automation of grain processing in large-scale processing.

[0029] In some embodiments, the grinding assembly 200 may optionally include a grinding cylinder 210 and a grinding roller 220, with an inlet 211 and an outlet 212 respectively disposed on opposite sides of the grinding cylinder 210, and the grinding roller 220 disposed inside the grinding cylinder 210 in a direction from the inlet 211 to the outlet 212, and the grinding roller 220 being movably disposed to grind the grain flowing in from the inlet 211 into powder.

[0030] A grinding chamber is formed inside the grinding cylinder 210, with an inlet 211 and an outlet 212 located at the top and bottom of the grinding cylinder 210, respectively. A grinding roller 220 is positioned inside the grinding cylinder 210 along the direction from the inlet 211 to the outlet 212. The grinding roller 220 is driven to rotate by a motor, extruding, shearing, and grinding the grains. Preferably, an adjustable gap adjustment mechanism is provided between the grinding roller 220 and the inner wall of the grinding cylinder 210 to control the fineness of the powder.

[0031] In some embodiments, the first clamping mechanism 320 may optionally include a first guide rod 321, a plurality of first fixing plates 322 and a plurality of first clamping members 323.

[0032] The first guide rod 321 is fixed vertically or inclinedly to the frame 100 and is arranged side by side with the fixing frame 310. The first fixing plate 322 is slidably sleeved on the first guide rod 321 via a sliding sleeve and is equipped with a locking component (such as a locking screw) to fix its position. The first clamping component 323 is correspondingly connected to the first fixing plate 322. By adjusting the height of the first fixing plate 322 on the guide rod, it can accommodate packaging bags 20 of different heights.

[0033] In some embodiments, optionally, the first gripping element 323 includes a suction cup, and there are multiple first gripping elements 323, each corresponding to a corner of the packaging bag 20. Further, the first gripping element 323 is a vacuum suction cup and is connected to an external vacuum generator via a vacuum line. There are multiple first gripping elements 323 (preferably two or four), each corresponding to a corner of the packaging bag 20, to ensure stable adhesion and a regular shape when the bag opening is open.

[0034] In some embodiments, the second clamping mechanism 330 may optionally include a second guide rod 331, a plurality of second fixing plates 332 and a plurality of second clamping members 333.

The second fixing plates 332 are movably disposed on the second guide rod 331, and the second clamping members 333 are correspondingly connected to the second fixing plates 332.

[0035] In some embodiments, the second gripper 333 may optionally include a suction cup, and there may be a plurality of second grippers 333, each of which is provided for a different corner of the packaging bag 20.

[0036] The second guide rod 331 is positioned opposite and spaced apart from the fixing frame 310 or the first clamping mechanism 320. The second fixing plate 332 is movably mounted on the second guide rod 331 and also has a locking mechanism. The second clamping member 333 is correspondingly connected to the second fixing plate 332. The second clamping member 333 is preferably a vacuum suction cup, and its number corresponds to the first clamping member 323, with each member positioned at one of the corners of the packaging bag 20.

[0037] In some embodiments, the clamping assembly 300 may optionally include a first transfer mechanism 340, which includes a first fixed platform 341 and a first driving member 342. The first fixed platform 341 and the fixed frame 310 are disposed opposite to each other. The fixed end of the first driving member 342 is disposed on the first fixed platform 341, and the movable end of the first driving member 342 is connected to the second clamping mechanism 330.

[0038] The first transfer mechanism 340 is used to drive the second clamping mechanism 330 to reciprocate between the fixed frame 310 and the first clamping mechanism 320. The first transfer mechanism 340 includes a first fixed platform 341 and a first driving member 342 (such as a cylinder, hydraulic cylinder, or electric push rod). The first fixed platform 341 and the fixed frame 310 are arranged opposite to each other. The cylinder body of the first driving member 342 is fixed on the first fixed platform 341, and the movable end of the piston rod is connected to the second guide rod 331 of the second clamping mechanism 330.

[0039] The first transfer mechanism 340 includes a horizontally arranged first fixed platform 341 and a first driving member 342. The first fixed platform 341 spans above the fixed frame 310 and the first gripping mechanism 320. The first driving member 342 is preferably a rodless cylinder or a slide cylinder, and its movable slider is fixedly connected to the second guide rod 331 of the second gripping mechanism 330. When the first driving member 342 is activated, it drives the entire second gripping mechanism 330 to reciprocate in the horizontal direction: first moving to the fixed frame 310 to grab the packaging bag 20, and then moving to the front of the first gripping mechanism 320.

[0040] In some embodiments, the clamping assembly 300 may optionally include a second transfer mechanism 350, which includes a second fixed platform 351 and a second driving member 352. The second fixed platform 351 is disposed opposite to the first clamping mechanism 320 and is disposed side by side with the first fixed platform 341. The second driving member 352 is movably disposed along the second fixed platform 351.

[0041] The second transfer mechanism 350 is used in conjunction with the first clamping mechanism 320 to open the opening of the packaging bag 20. The second transfer mechanism 350 includes a second fixed platform 351 and a second driving member 352 (such as a lead screw module or a slide cylinder). The second fixed platform 351 is disposed opposite to the first clamping mechanism 320 and is arranged side by side with the first fixed platform 341. The second driving member 352 is movably disposed along the second fixed platform 351. The movable end of the second driving member 352 can be connected to the first clamping mechanism 320 or cooperate with the first driving member 342 to open the opening of the packaging bag 20 to a predetermined width through relative movement after the second clamping mechanism 330 clamps one side of the packaging bag 20.

[0042] The second transfer mechanism 350 includes a second fixed platform 351 and a second driving member 352. The second fixed platform 351 is arranged side by side with the first fixed platform 341. The second driving member 352 is preferably a lead screw module or a cylinder. In this embodiment, the movable end of the second driving member 352 is connected to the first clamping mechanism 320 (or connected to the second clamping mechanism 330, depending on the specific opening direction). When the second clamping mechanism 330 clamps the packaging bag 20 and moves it into place, and cooperates with the first clamping mechanism 320 to adsorb both sides of the packaging bag 20, the second driving member 352 is activated, driving the first clamping mechanism 320 (or the second clamping mechanism 330) to move away from each other, thereby opening the bag opening of the packaging bag 20 laterally to form a spacious receiving port.

[0043] Workflow: S102, Reset and standby, the equipment starts, the first driving component 342 drives the second clamping mechanism 330 to move directly above the fixed frame 310, and the first clamping mechanism 320 is positioned below the discharge port 212 and ready to be used.

[0044] S104. Bag Removal: The second gripping component 333 (suction cup) of the second gripping mechanism 330 actuates, adsorbing the front side of the topmost packaging bag 20 on the fixing frame 310. Subsequently, the first driving component 342 actuates, driving the second gripping mechanism 330 and the packaging bag 20 to move backward until the rear side of the packaging bag 20 is directly facing the first gripping mechanism 320.

[0045] S106. Clamping and Opening: The first clamping member 323 of the first clamping mechanism 320 actuates, adsorbing the rear side of the packaging bag 20. At this time, the front and rear sides of the packaging bag 20 are respectively gripped by the second clamping mechanism 330 and the first clamping mechanism 320. Next, the second driving member 352 of the second transfer mechanism 350 actuates, driving the first clamping mechanism 320 and the second clamping mechanism 330 to move away from each other (for example, the first clamping mechanism 320 remains stationary while the second clamping mechanism 330 moves backward; or both actuate simultaneously), thereby opening the packaging bag 20 into a rectangular shape.

[0046] S108, receiving material: the grinding component 200 starts working, and the ground powder falls into the packaging bag 20 below through the discharge port 212.

[0047] S110. Unloading: After receiving the material, the first and second clamping parts 333 release pressure and loosen the packaging bag 20. The packaging bag 20 filled with powder falls into the conveyor belt or collection box below, completing one work cycle.

[0048] The beneficial effects of this invention are as follows: 1. High degree of automation: Through the cooperation of the first and second clamping mechanisms 330 and the transfer mechanism, the entire process from bag picking, opening, to material receiving is completed automatically without manual intervention. 2. Strong versatility: The positions of the first and second fixing plates 332 on the guide rod are adjustable, and the suction cup clamping components can adapt to packaging bags 20 of different sizes and materials. 3. Precise and hygienic material receiving: The opening of the packaging bag 20 is firmly opened and aligned with the discharge port 212, effectively preventing powder spillage and dust from flying. 4. Compact structure: The components are rationally arranged, with the fixing frame 310, the first clamping mechanism 320, and the second clamping mechanism 330 arranged sequentially, resulting in a smooth operation process.
