Preferably, it is set to be circular. The turntable 10 can rotate. Those skilled in the art can set the rotation mode of the turntable 10 according to actual needs. Preferably, a rotation driver 12 is provided to drive the turntable 10 to rotate. Preferably, the rotation driver 12 is set as a cam divider. A plurality of workstations are sequentially arranged on the turntable 10 along its circumferential direction. The workstations are used to set the silo 20. During actual use, by rotating the turntable 10, the silo 20 on the corresponding workstation of the turntable 10 is rotated to the corresponding operation workstation for corresponding operations, so as to realize efficient and continuous operations and improve production efficiency.

[0028] The silo 20 is used to hold materials, and those skilled in the art can set the shape and size of the silo 20 according to actual needs. There are multiple silos 20. Preferably, the number of silos 20 is a positive integer multiple of the number of workstations on the turntable 10. Each silo 20 can be detachably arranged on the corresponding workstation; those skilled in the art can set the specific detachable connection structure according to actual needs, such as snap connection, threaded connection, etc. By setting the detachable connection structure, after completing the relevant operation actions for a certain type of material, the silo 20 arranged on the turntable 10 can be removed, and then the silo 20 corresponding to another type of material can be replaced, and subsequent operations can be carried out, which is fast and efficient. It can not only save the space and cost required for multiple devices corresponding to different models, but also avoid the problems of affecting the space utilization rate and high cost of the device itself due to setting additional driving structures on the device, effectively saving the energy consumption during a single rotation operation and saving costs. Preferably, when replacing the silo 20, the corresponding materials can be pre-set in the silo 20 to be replaced to save time.

[0029] The pressing member 30 is used to fix the silo 20, enhance the structural stability, and avoid problems such as the detachment and separation of the detachable connection type silo 20 during rotation. The pressing member 30 is connected to the turntable 10. The pressing member 30 includes a pressing state and a separating state. When the pressing member 30 presses and fixes the silo 20, the pressing member 30 enters the pressing state, so that the silo 20 can rotate stably and firmly with the turntable 10, preventing problems such as detachment and separation; when the pressing member 30 is separated from the silo 20, the pressing member 30 enters the separating state, thus facilitating the replacement of the silo 20. Those skilled in the art can set the specific pressing member 30 according to actual needs to achieve the pressing and fixing and separation of the silo 20, such as by setting a buckle structure, etc.

[0030] In the feeding device of the present utility model, multiple silos 20 are arranged on the turntable 10, and the corresponding silos 20 are rotated to the corresponding workstations by rotating the turntable 10 to achieve feeding, effectively improving production efficiency. After completing the feeding of a certain type of material, the silo 20 can be directly replaced and subsequent operations can be carried out, which is fast and efficient. It can not only save the space and cost required for multiple devices corresponding to different models, but also avoid the problems of affecting the space utilization rate and high cost of the device itself due to setting additional driving structures on the device, effectively saving the energy consumption during a single rotation operation and saving costs. The setting of the pressing member 30 effectively improves the stability of the connection structure between the silo 20 and the turntable 10, preventing problems such as detachment and separation.

A slider 34 is slidably arranged on the slide rail 31. When the slider 34 slides relative to the slide rail 31, the slider 34 can be limited by the first limiting member 32 and the second limiting member 33.

The limiting surfaces 221 of the plurality of limiting members 22 can enclose to form a receiving space 23 for receiving the material. Among them, the limiting member 22 can be fixed after moving along the mounting groove 212 to adjust the size of the receiving space 23. Preferably, the limiting member 22 and the mounting groove 212 are fixedly connected by screws. Specifically, when fixation is required, the screws are tightened so that the limiting member 22 and the base 21 are relatively fixed; when assembly and debugging are required, the screws are loosened for debugging. By providing this structure, the base 21 is universal and only the corresponding limiting member 22 needs to be replaced, saving costs; in addition, it is also convenient for the limiting member 22 to approach inward from a larger size during assembly and debugging, and after reaching the appropriate size, the limiting member 22 and the base 21 are relatively fixed so that the material and the receiving space 23 are adapted to each other, and problems such as material jamming will not occur.

[0040] Working principle:

[0041] During the first use, the bin 20 provided with the corresponding model of material is fixed to the turntable 10. The turntable 10 rotates under the drive of the cam divider. When the bin 20 rotates to the first lifting member 40, the turntable 10 stops rotating and, in cooperation with the first lifting member 40, the feeding of the material in the bin 20 is realized. During the feeding process, the positioning member 50 can cooperate with the feeding to maintain the consistency of the position. After the feeding is completed, the turntable 10 rotates to make the bin 20 rotate to the second lifting member 60 for replenishing the material, and at the same time, the next bin 20 is fed, and so on in a cycle. After the feeding of the material of the same model is completed, the staff adjusts the pressing member 30 to replace the bin 20 for subsequent operations.
