The rotating member 2 is arranged inside the fixed frame 1 for conveying the material. The connecting member 4 is arranged outside the rotating member 2 for adjusting the rotating member 2. The adjusting member 3 is arranged outside the rotating member 2 for controlling the connecting member 4. The driving member 5 is arranged outside the connecting member 4 for connecting the connecting member 4. The rotating member 2, the adjusting member 3, the connecting member 4 and the driving member 5 cooperate to convey materials of different sizes. Specifically, when weighing and packaging materials, first place the materials to be weighed into the storage barrel 101 for temporary storage. Then, adjust the rotating member 2 through the cooperation of the adjusting member 3 and the connecting member 4 according to the size of the material to ensure that the material can move stably inside the rotating member 2. The fixed frame 1 controls the falling flow rate of the material in cooperation with the sliding plate 102 during the weighing process to ensure that the material can move evenly inside the rotating member 2.

The rotating rollers slide inside the sliding grooves 204, and the sliding direction of the rotating rollers is parallel to the height direction of the support plates 201. A weighing member 6 for measuring the weight of the material is further provided outside the support plates 201. Specifically, during use, the first conveyor belt 202 and the second conveyor belt 203 are driven to rotate by the rotating rollers. The rotating second conveyor belt 203 conveys the material discharged from the storage bucket 101. The first conveyor belt 202 is made of rubber material to increase the friction during the material conveyance. By adjusting the distance between the first conveyor belt 202 and the second conveyor belt 203, materials of different sizes can be conveyed. The sliding grooves 204 guide the moving direction of the rotating rollers during use to ensure the stability of the rotating rollers during movement. The weighing member 6 can weigh the material during use. The weighing member 6 is a prior art and will not be explained in detail here.

[0038] As Figures 1 to 11 shown, a guiding groove 208 is further formed outside the support plate 201. Multiple guiding grooves 208 are provided. A guiding rod 207 and a sliding block 205 are sequentially provided inside the guiding groove 208. The guiding rod 207 is connected to the support plate 201. The sliding block 205 slides outside the guiding rod 207. A first spring 206 is further sleeved outside the guiding rod 207. Specifically, the guiding grooves 208 and the guiding rod 207 can guide the sliding block 205 to ensure the stability of the sliding block 205 during movement.

[0039] As Figures 1 to 11As shown, the connecting member 4 includes a first connecting rod 401 and a second connecting rod 402. There are multiple first connecting rods 401 and second connecting rods 402. The first connecting rods 401 and the second connecting rods 402 are distributed on both sides of the first conveyor belt 202 and the second conveyor belt 203, and the first connecting rods 401 and the second connecting rods 402 are connected to the rotating rollers. Sliding rods 404 are provided on the outer sides of adjacent first connecting rods 401 and second connecting rods 402. Fixed plates 403 are provided on the outer sides of the sliding rods 404. The fixed plates 403 slide on the outer sides of the sliding rods 404. The sliding direction of the fixed plates 403 is parallel to the height direction of the support plate 201, and the fixed plates 403 are connected to the support plate 201. Second springs 405 are sleeved on the outer sides of the sliding rods 404. Rotating grooves 407 are formed on one side of the opposite surfaces of adjacent first connecting rods 401 and second connecting rods 402. Rollers 408 are provided inside the rotating grooves 407. Specifically, the rotating rollers inside the first conveyor belt 202 and the second conveyor belt 203 are connected by the first connecting rods 401 and the second connecting rods 402 respectively to ensure that the distance between the first conveyor belt 202 and the second conveyor belt 203 is adjusted evenly. The fixed plates 403 and the support plate 201 can be connected by welding or bolts to ensure the stability of the position of the fixed plates 403 during use. The sliding rods 404 guide the moving direction of the first connecting rods 401 and the second connecting rods 402 in cooperation with the fixed plates 403 during use. The second springs 405 can provide a thrust force for the first connecting rods 401 and the second connecting rods 402 to move towards each other during use. Thus, when the distance between the first connecting rods 401 and the second connecting rods 402 is reduced, the second springs 405 can provide power for the first connecting rods 401 and the second connecting rods 402. There are no restrictions on the shape of the sliding rods 404, which can be cylindrical, hexagonal prism-shaped, or square prism-shaped, etc.

[0040] As Figures 1 to 11As shown, the adjusting member 3 includes control rods 301. There are multiple control rods 301, and the control rods 301 slide between adjacent first connecting rods 401 and second connecting rods 402. The sliding direction of the control rods 301 is parallel to the length direction of the support plate 201. Adjusting blocks 306 are provided on both the control rods 301 relative to the first connecting rod 401 and the sliding groove 204 side, and the adjusting blocks 306 are in contact with the rollers 408. A fixed rod 304 and a connecting frame 302 are sequentially provided at the end of the control rod 301 relative to the storage barrel 101. A threaded rod 303 is threadedly connected inside the connecting frame 302, and one end of the threaded rod 303 is connected to the storage barrel 101. Specifically, during use, first rotate the threaded rod 303 according to the size of the material. During the rotation of the threaded rod 303, the threaded rod 303 and the fixed rod 304 are driven to move in position. During the movement, the fixed rod 304 drives the control rod 301 and the adjusting block 306 to move relative to the first connecting rod 401 and the second connecting rod 402. While the control rod 301 is moving, the distance between the first connecting rod 401 and the second connecting rod 402 is adjusted through the cooperation of the adjusting block 306 and the roller 408 to ensure that the first conveyor belt 202 and the second conveyor belt 203 can stably convey the material. The connecting frame 302 and the fixed rod 304 are connected by bolts. The roller 408 can rotate relative to the adjusting block 306 during use, thereby reducing the resistance during the movement of the adjusting block 306. The adjusting block 306 and the control rod 301 can be connected by pins or bolts, which is convenient for quickly replacing the adjusting block 306 during use.

[0041] As Figures 1 to 11As shown in the figure, the driving member 5 includes a connecting belt 501. On the outer side of the connecting belt 501, a second pulley 505, a third pulley 506, and a first pulley 503 are respectively meshed. The second pulley 505 and the third pulley 506 are respectively rotatably connected to the second connecting rod 402 and the first connecting rod 401, and the second pulley 505 and the third pulley 506 are connected to the rotating roller. On the outer side of the first pulley 503, a moving block 502 is provided, and the moving block 502 is connected to the sliding block 205. On the outer side of the third pulley 506, a transmission box 504 is provided, and the transmission box 504 is connected to the first connecting rod 401. Specifically, a motor is provided on the outer side of the transmission box 504. During use, the motor cooperates with the transmission box 504 to drive the third pulley 506 to rotate. During use, the second pulley 505 and the third pulley 506 are connected through the connecting belt 501 to ensure that the third pulley 506 and the second pulley 505 can rotate synchronously and reversely, avoiding rubbing the material during the rotation of the second conveyor belt 203 and the first conveyor belt 202. The connecting belt 501 is a double-sided toothed synchronous belt to ensure that the connecting belt 501 can drive the third pulley 506 and the second pulley 505 to rotate synchronously during use. During the adjustment of the distance between the first connecting rod 401 and the second connecting rod 402, the tension of the connecting belt 501 is automatically adjusted through the cooperation of the moving block 502 and the first spring 206 to ensure that the connecting belt 501 can stably mesh with the second pulley 505 and the third pulley 506 during use.

[0042] As Figures 1 to 11 shown in the figure, grooves 406 are respectively provided on the sides of the first connecting rod 401 and the second connecting rod 402 relative to the fixing plate 403. Specifically, during the movement of the first connecting rod 401 and the second connecting rod 402, the movement range of the first connecting rod 401 and the second connecting rod 402 is increased through the setting of the grooves 406.

[0043] As Figures 1 to 11 shown in the figure, a guiding groove is further provided on the side of the control rod 301 relative to the supporting plate 201. A guiding strip 305 is slidably connected inside the guiding groove, and the guiding strip 305 is connected to the supporting plate 201. Specifically, while the guiding strip 305 cooperates with the guiding groove to guide the control rod 301, it also limits the position of the control rod 301, further ensuring the stability of the control rod 301 during movement. The guiding strip 305 is connected to the supporting plate 201 through bolts. The guiding strip 305 has the same shape as the guiding groove, and the guiding strip 305 can be in the shape of a T-shaped long strip or a dovetail-shaped long strip.

[0044] As Figures 1 to 11 shown in the figure, a plurality of adjusting grooves 307 are further provided on the side of the adjusting block 306 relative to the roller 408. Specifically, during use, the distance between the first connecting rod 401 and the second connecting rod 402 is quickly adjusted through the cooperation of the adjusting grooves 307 and the roller 408.

[0045] As Figures 1 to 11 shown, the working state of the multi-channel material weighing and packaging equipment XX is as follows: during use, first place the material to be weighed inside the storage barrel 101. Then, through the cooperation of the threaded rod 303 and the connecting frame 302, control the position movement of the control rod 301 and the adjusting block 306. While the control rod 301 and the adjusting block 306 are moving, the first connecting rod 401 and the second connecting rod 402 are pushed to move towards or away from each other by the roller 408. During the movement of the second connecting rod 402 and the first connecting rod 401, the distance between the first conveyor belt 202 and the second conveyor belt 203 is adjusted to ensure that the first conveyor belt 202 and the second conveyor belt 203 can clamp the material during use, avoiding the material sliding relative to the second conveyor belt 203 under the action of inertia after the second conveyor belt 203 stops rotating, and ensuring the accuracy of material addition.

[0046] In summary, the present invention includes: a fixed frame 1, a storage barrel 101 is provided at the top of the fixed frame 1, and there are multiple storage barrels 101.

The control mechanism includes a rotating member 2, an adjusting member 3, a connecting member 4, and a driving member 5. The rotating member 2 is arranged inside the fixed frame 1 for conveying the material. The connecting member 4 is arranged outside the rotating member 2 for adjusting the rotating member 2. The adjusting member 3 is arranged outside the rotating member 2 for controlling the connecting member 4. The driving member 5 is arranged outside the connecting member 4 for connecting the connecting member 4. The rotating member 2, the adjusting member 3, the connecting member 4, and the driving member 5 cooperate to convey materials of different sizes. Through the arrangement of the rotating member 2, the adjusting member 3, the connecting member 4, and the driving member 5, the present invention realizes the cooperation of the support plate 201, the first conveyor belt 202, the second conveyor belt 203, the control rod 301, the adjusting block 306, the first connecting rod 401, the second connecting rod 402, the connecting belt 501, the moving block 502, the first belt pulley 503, the second belt pulley 505, and the third belt pulley 506, thereby clamping and conveying the material, avoiding the material being directly placed on the top of the conveyor belt, so that when the conveyor belt stops conveying, the material on the top of the conveyor belt moves forward under the action of inertia, thereby reducing the weighing error.
