Example one

The embodiment of the application discloses filling mechanism convenient to weigh, refer to fig. 1, including frame 1, be equipped with material jar 6, feed bin 2 and filling head 3 in the frame 1. Material jar 6 supplements the material in the feed bin 2, and feed bin 2 is squeezed into the material in the filling head 3 to carry out the filling through filling head 3.

Referring to fig. 1, a support rod 11 for supporting the filling heads 3 is fixed on the frame 1, and the filling heads 3 are horizontally and slidably connected to the support rod 11. The operator can adjust the position of the filling heads 3 according to the size and dimensions of the containers to be filled, and the spacing between the filling heads 3 can be changed to adapt to the size of the containers to be filled.

Referring to fig. 2, a plurality of weighing stations 4 are mounted on a rack 1, each weighing station 4 includes a base 41, a weighing sensor 42 mounted on the base 41, and a support table 43 located above the weighing sensor 42, and the bins 2 correspond to the weighing stations 4 one to one. A magazine 2 is fixed to a support table 43. The load cell 42 weighs the silo 2 so that the remaining content of the material in the silo 2 is known.

Referring to fig. 2, the number of the bunkers 2 is consistent with the number of the filling heads 3 and is connected with the filling heads 3 in a one-to-one correspondence manner. Be equipped with on the filling head 3 and be used for the inlet pipe 31 that links to each other with feed bin 2, be equipped with on the feed bin 2 and be used for the discharging pipe 21 that links to each other with filling head 3. The feed pipe 31 and the discharge pipe 21 are connected by a damping mechanism.

Referring to fig. 2, when filling, the material is discharged from discharging pipe 21 of silo 2 and enters into filling head 3 through feeding pipe 31, and finally the filling is performed through discharging of filling head 3. When weighing, on external vibration passes through frame 1 transmission to filling head 3, and when filling head 3 will vibrate through inlet pipe 31 to 2 transmissions in feed bin, damping mechanism can weaken the vibrational force of filling head 3 to reduce the influence of external vibration to feed bin 2, improve the precision of weighing of feed bin 2.

Referring to fig. 2, the damping mechanism includes a flexible pipe 51, and one end of the flexible pipe 51 is connected to the feed pipe 31 via a flange and the other end is connected to the discharge pipe 21 via a flange. The length of flexible tube 51 is greater than the distance between discharge tube 21 and feed tube 31, i.e. flexible tube 51 is in a relaxed state. The vibration that the filling head 3 receives is transmitted to on the flexible tube 51, and the material of flexible tube 51 itself is softer, is in moreover relaxed state and can cushions the absorption to the vibrational force to reduce the influence of vibration to feed bin 2.

With reference to fig. 2, during filling of the material, the filled containers are conveyed by conveyor belts underneath the filling head 3 in order to ensure an in-line filling speed of the material. The filled containers are arranged closely below the filling head 3, i.e. they lie closely against one another. The size of the filled containers, in particular the horizontal width, therefore influences the distance of the filling heads 3 from one another. The distance between the filling head 3 and the filling head 3 is small when the size of the container to be filled is small, in particular the width dimension horizontally upwards. The traditional filling machine is limited by the direct connection between the bin 2 and the filling head 3, so that the gap between the filling heads 3 is limited by the size of the bin 2, and the filled containers with small sizes are difficult to fill.

The material jar 6 is not direct to link to each other with feed bin 2, and consequently, the material jar 6 receives the vibrational force of the vibration transmission feed bin 2 of frame 1 less to in order to improve the weighing precision of feed bin 2.

Referring to fig. 2, the number of the material conveying pipes 61 is the same as that of the filling heads 3, the material conveying pipes 61 correspond to the filling heads 3 one by one, one material conveying pipe 61 corresponds to one filling head 3 and is connected with the corresponding material conveying pipe 31 on the filling head 3, and the material conveying pipes 61 are connected with the corresponding material conveying pipe 31 on the filling head 3. Each material conveying pipe 61 is provided with a control valve (not shown in the figure) for controlling the material conveying pipe 61 to open and close, and one end of the feed pipe 31 close to the filling head 3 is connected with a valve for controlling the feed pipe 31 to open and close. When the material in a certain silo 2 is low, the corresponding control valve is opened, and the material in the charging bucket 6 flows into the feeding pipe 31 through the feeding pipe 61 and flows into the silo 2 through the discharging pipe 21. The feeding pipe 31 can be used for filling after discharging materials, can also be used for increasing the filling of the materials in the storage bin 2, and is convenient to use.

The implementation principle of filling mechanism convenient to weigh of this application embodiment is: during the filling, operating personnel adjusts the position of filling head 3 according to the size by the filling container, adjusts to corresponding position after, and feed bin 2 opens, and the material passes through discharging pipe 21, flexible pipe 51, inlet pipe 31 in proper order and gets into filling head 3, finally discharges by the filling container in through filling head 3 in, accomplishes the filling. After the filling was accomplished, weighing platform 4 weighs feed bin 2 to know the interior material surplus condition of feed bin 2. When the material in the bin 2 is less, the material in the charging bucket 6 is discharged into the feeding pipe 31 through the feeding pipe 61, and then enters the bin 2 through the discharging pipe 21 to supplement the material in the bin 2. When frame 1 received the external vibration, material jar 6 and filling head 3 are followed vibration together, and feed bin 2 links to each other with filling head 3 through flexible pipe 51, and the vibration transmits the vibrational force on feed bin 2 through flexible pipe 51 less, and the vibration influence that feed bin 2 receives is less to can improve the precision of weighing of feed bin 2.
