[0002] Feeding mechanism refers to the equipment used to transport raw materials, parts and other materials to the processing or assembly position in machinery, automation equipment or production lines. Its main function is to ensure the continuity and efficiency of the production process. Feeding mechanism plays a vital role in industries such as automated production, packaging, and food processing.

[0003] Common feeding mechanism types include vibrating feeders, screw feeders and belt conveyors. Screw feeders are usually used to deliver fixed materials through the rotating motion of the screw.

[0004] In the production process of multi-component products, it is often necessary to mix materials of different weights and ingredients according to specific ratios to achieve a predetermined product formula in order to maintain product quality and performance. However, if the existing feeding mechanism needs to mix materials of different weights, the operator is required to continuously adjust the weight of the material or remove and replace the material barrels of different capacities, which increases the feeding and material discharging time, affects production efficiency, and is difficult to meet the different material discharging needs of customers. Therefore, it is necessary to provide a solid feeding mechanism to solve the above problems.

Detailed implementation manners

[0029] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to detail this application.

[0030] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0031] As Figure 1 - Figure 2As shown in the figure, the present application provides a solid feeding mechanism, including a stirring barrel 1. One side of the stirring barrel 1 is provided with a feeding end 11, through which the material to be fed can conveniently enter the interior of the stirring barrel 1. The outside of the stirring barrel 1 is fixedly installed with a support frame 12, which is used to support the stirring barrel 1;

[0032] The lower end of the stirring barrel 1 is connected to a spiral discharge pipe 13 through a pipeline. One side end of the spiral discharge pipe 13 away from the stirring barrel 1 is provided with a discharge hole (not shown in the figure). The spiral discharge pipe 13 is used to transport the material in the stirring barrel 1 to the discharge hole. The spiral discharge pipe 13 is a prior art and can be specifically consulted in relevant materials, so it will not be elaborated here.

[0033] At the same time, a feeding component 2 is arranged at the discharge port of the spiral discharge pipe 13. The feeding component 2 has a three-way valve 21. The upper port of the three-way valve 21 is provided with a connecting pipe 22, and the connecting pipe 22 is connected to the discharge port of the spiral discharge pipe 13 through a pipeline;

[0034] Moreover, the lower two outlets of the three-way valve 21 are respectively connected to a first extension pipe 23 and a second extension pipe 24 through pipelines. And an adjustment switch 25 is arranged at the center of the first extension pipe 23 and the second extension pipe 24. A fan blade for blocking the flow channel is arranged in the three-way valve 21. The position of the fan blade can be controlled by the adjustment switch 25 to adjust the separate communication between the connecting pipe 22 and the first extension pipe 23 or the second extension pipe 24, so that the material entering from the connecting pipe 22 can selectively flow out from the first extension pipe 23 or the second extension pipe 24, and the first extension pipe 23 and the second extension pipe 24 can also be completely closed by the adjustment switch 25.

[0035] As Figure 2 - Figure 3 shown, a weighing mechanism 3 is arranged below the first extension pipe 23 and the second extension pipe 24. The weighing mechanism 3 is used to weigh the discharged material. The weighing mechanism 3 has a first weighing bucket 31 and a second weighing bucket 32, and the weighing capacities of the first weighing bucket 31 and the second weighing bucket 32 are inconsistent; a first spring scale 33 is installed at the upper end of the first weighing bucket 31, and a second spring scale 34 is installed at the upper end of the second weighing bucket 32. In the present application, the two output ends of the first spring scale 33 are respectively installed on the first weighing bucket 31 and the first extension pipe 23, and the two output ends of the second spring scale 34 are installed on the second weighing bucket 32 and the second extension pipe 24. During weighing, when the material enters the first weighing bucket 31 or the second weighing bucket 32, the gravity of the material will cause it to move downward, so the data of the first spring scale 33 and the second spring scale 34 will change with the gravity.

[0036] It should be noted that the lower ends of the first extension pipe 23 and the second extension pipe 24 are respectively connected to a blanking pipe 26 through pipelines. The first weighing bucket 31 and the second weighing bucket 32 are sleeved outside the blanking pipe 26, so as to prevent the material from falling outside during the blanking process.

[0037] In this application, the bottoms of the first weighing bucket 31 and the second weighing bucket 32 are arranged to be through. On both sides of the bottom of the first weighing bucket 31, a first blanking mechanism 36 is provided. On both sides of the bottom of the second weighing bucket 32, a second blanking mechanism 35 is provided. In this application, the structures of the first blanking mechanism 36 and the second blanking mechanism 35 are the same. For the convenience of understanding, the following takes the first blanking mechanism 36 as an example to expand the description. Specifically:

[0038] The first blanking mechanism 36 has a rotating plate 361 hinged to the lower end of the first weighing bucket 31. The other end of the rotating plate 361 is fixedly installed with an arc plate 362. The arc plate 362 is arranged to be semi-circular. It should be noted that rubber pads are fixedly installed on the opposite surfaces of the arc plate 362. When the two arc plates 362 rotate to the lower end of the first weighing bucket 31, at this time, the two arc plates 362 are spliced into a circle and seal the lower end of the first weighing bucket 31.

[0039] In order to better control the rotation of the arc plate 362, a fixing frame 363 is fixedly installed on the barrel wall of the first weighing bucket 31. The lower end of the fixing frame 363 is rotatably connected to a cylinder 364. A hinge member 365 is fixedly installed on the output shaft of the cylinder 364. The other end of the hinge member 365 is fixedly installed on the arc plate 362. Therefore, when the cylinder 364 is started to push its output shaft outwards, and drive the hinge member 365 outwards, at the same time, push the arc plate 362 to rotate inwards along with the rotating plate 361 until the arc plate 362 is attached to the lower end of the first weighing bucket 31 to seal the bottom of the first weighing bucket 31.

[0040] It should be noted that the first spring scale 33, the second spring scale 34 and the cylinder 364 are electrically connected to the adjustment switch 25. When the data of the first spring scale 33 reaches the set data, the adjustment switch 25 will close the first extension pipe 23, and at the same time start the cylinder 364 to contract and reset, driving the arc plate 362 to open; and when the data of the first spring scale 33 returns to zero, at this time, the adjustment switch 25 will open the first extension pipe 23, and the cylinder 364 will extend outwards, pushing the arc plate 362 to rotate inwards until it reaches the bottom of the first weighing bucket 31.

[0041] The circuit control of the above components can be realized through a PLC control system. As for the specific implementation method, it is a conventional technology in this field and will not be elaborated here.

[0042] In this application, in the normal state, the arc plate 362 is located at the bottom of the first weighing bucket 31 and seals it.

[0043] In summary, when it is necessary to use the feeding mechanism to dispense materials of different weights, the operator first adjusts the adjusted weights of the first weighing bucket 31 and the second weighing bucket 32. For the weighing bucket that needs to be discharged first, when it is necessary to discharge the materials in the first weighing bucket 31, at this time, the connection pipe 22 and the first extension pipe 23 are connected through the adjustment switch 25. The materials in the mixing bucket 1 enter the three-way valve 21 along the spiral discharge pipe 13, and then flow into the first extension pipe 23 and then into the first weighing bucket 31;

[0044] When the first spring scale 33 reaches the set data, at this time, the adjustment switch 25 closes the first extension pipe 23, and at the same time, the air cylinder 364 contracts to open the arc plate 362, so that the materials are discharged downward. Then the air cylinder 364 extends and resets, resets the arc plate 362 and seals the first weighing bucket 31. At the same time, the adjustment switch 25 opens the first extension pipe 23. Repeating the above operations can complete batch feeding;

[0045] When it is necessary to discharge the materials in the second weighing bucket 32 during the process, similarly, the connection pipe 22 and the second weighing bucket 32 are connected through the adjustment switch 25, and then the normal discharging can be carried out. Therefore, when using the feeding mechanism to dispense materials of different weights, the operator does not need to continuously adjust the feeding weight, and there is no need to remove and replace the feeding buckets of different capacities, reducing the feeding and discharging time, improving the production efficiency, and at the same time meeting the different feeding requirements of customers.

[0046] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
