Description

Technical Field

[0001] The utility model relates to a feeding mechanism, in particular to a servo feeding mechanism. Background Art

[0002] In packaging machinery, for granular or powdery materials, the product packaging is generally carried out by means of the cooperation between a feeding mechanism and a packaging mechanism. Its working principle is that the granular or powdery materials are poured into the feeding mechanism, and the storage bin of the feeding mechanism is responsible for storing the granular or powdery materials. When the packaging mechanism sends the packaging bag to the material dropping port of the feeding mechanism, the switch door assembly arranged at the material dropping port works to open the material dropping port, and the granular or powdery materials fall into the packaging bag from the material dropping port. After a single feeding is completed, it will reset to close the material dropping port. After the packaging mechanism packs the packaging bag, it sends it to the next working station and sends a new packaging bag to the material dropping port. In this way, the continuous packaging of the granular or powdery materials can be completed. However, the existing feeding mechanism has the following problems: the granular or powdery materials cannot be normally discharged when they are in a bulking state. The bulking state of the granular or powdery materials refers to the state in which the granular or powdery materials are agglomerated and have poor fluidity. When the material dropping door is opened, the materials are likely to be in a bulking state due to mutual extrusion in the storage bin. In this case, even if the material dropping port is opened, effective feeding cannot be achieved, which will lead to untimely feeding, inaccurate feeding amount, and even the situation of no material dropping, seriously affecting the production efficiency.

Specific embodiments

[0034] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] Refer to Figures 1 - 8 , a servo feeding mechanism of the present utility model includes a servo motor 1, a clamping body 2, a rotating shaft 3, a dispersing plate 4, a feeding arc gate 5 and a torsion arm 6.

[0036] An upper feeding port and a lower discharging port are respectively provided at the top and bottom of the clamping body 2 for feeding and discharging materials. The rotating shaft 3 extends into the clamping body 2, and both ends of the rotating shaft 3 are respectively located in the mounting holes on the side walls of the clamping body 2 and are rotatably connected to the mounting holes.

[0037] The dispersing plate 4 is fixedly connected to the outer wall of the rotating shaft 3 located inside the clamping body 2. In this way, when the servo motor 1 rotates, the dispersing plate 4 will rotate synchronously under the drive of the rotating shaft 3, dispersing and dividing the materials in the clamping body 2, and destroying the expanded state due to mutual extrusion, ensuring the smooth discharge of materials.

[0038] The feeding arc gate 5 is arranged at the position of the lower discharging port to block the lower discharging port. The feeding arc gate 5 is fixedly connected to the rotating shaft 3. When the rotating shaft 3 is driven to rotate by the servo motor 1, the feeding arc gate 5 can be opened and closed. In this way, the rotation angle of the feeding arc gate 5 can be flexibly controlled by the servo motor 1. Different rotation angles correspond to different opening sizes of the lower discharging port, so that the discharging control of different speeds and different states can be realized.

[0039] The outer edge of the lower end of the lower discharge port projects as an arc on a plane perpendicular to the rotating shaft 3, and the axis of the rotating shaft 3 coincides with the center line of the arc-shaped outer edge at the lower end of the lower discharge port. To adapt to such a shape of the lower discharge port, the feeding arc gate 5 includes a feeding arc gate bottom plate 52 and connecting arms 51. The feeding arc gate bottom plate 52 is arranged at the position of the lower discharge port, and the feeding arc gate bottom plate 52 is adapted to the shape of the outer edge at the lower end of the lower discharge port. There are two connecting arms 51, and the two connecting arms 51 are respectively arranged at both ends of the feeding arc gate bottom plate 52 and are located outside the side wall of the clamping body 2. This can ensure that the feeding arc gate bottom plate 52 is evenly stressed. The lower ends of the two connecting arms 51 are fixedly connected to the feeding arc gate bottom plate 52, and the upper ends are fixedly connected to the rotating shaft 3. The two connecting arms 51 are located outside the side wall of the clamping body 2, which is convenient for installation and fixation.

[0040] Since the rotating shaft 3, the dispersing plate 4, and the feeding arc gate 5 are fixedly connected as a whole, for the convenience of assembly, in this embodiment, the clamping body 2 adopts a split structure, including a first clamping body 21 and a second clamping body 22. After the two are spliced along a vertical plane passing through the axis of the rotating shaft 3, they are bolted to form the clamping body 2. The top and bottom of the first clamping body 21 and the second clamping body 22 are respectively provided with notches. The notches at the top form an upper feeding port after splicing, and the notches at the bottom form a lower discharge port after splicing; and semicircular notches are opened on the side walls of the first clamping body 21 and the second clamping body 22 at the splicing surface. The semicircular notches form an installation hole after splicing.

[0041] The servo motor 1 is arranged outside the clamping body 2, and its output end is fixedly connected to one end of the rotating shaft 3. In this embodiment, the servo motor 1 adopts a torque arm installation form. Compared with the traditional motor that is fixedly installed using its own base or flange surface, the concentricity between the servo motor 1 and the rotating shaft 3 is higher, and the rotating shaft 3 will not be subjected to forces in other directions when rotating due to machining accuracy problems.

[0042] To install the torque arm 6, a limiting tube 221 is provided on the second clamping body 22. A limiting groove with an extending direction parallel to the axis direction of the rotating shaft 3 is opened on the limiting tube 221. The torque arm 6 is arranged between the side wall of the clamping body 2 and the servo motor 1. It includes a flange plate 61, a connecting tube 62, and a flexible stopper 63. The flange plate 61 is installed on the flange surface of the servo motor 1. The connecting tube 62 is located on the side of the flange plate 61 close to the second clamping body 22. One end of the flexible stopper 63 is connected to the connecting tube 62, and the flexible stopper 63 is clamped in the limiting groove. In this way, when the output end of the servo motor 1 rotates, the torque arm 6 will limit the rotation of the servo motor 1 housing. By using the flexible stopper 63, a certain elastic deformation can be provided when installing the torque arm 6 to make up for the machining error and ensure smooth installation.

[0043] During use, first add granular or powdered products through the upper feeding port of the clamping body 2, and then start the servo motor 1. The servo motor 1 drives the rotating shaft 3 to rotate, and the dispersing plate 4 rotates along with the rotation of the rotating shaft 3 to disperse and divide the materials. At this time, the feeding arc gate 5 synchronously rotates by a certain angle, the lower discharging port opens, and the materials fall. Then, according to the requirements, the rotation angle of the feeding arc gate 5 is adjusted in real time to control the discharging speed. After the feeding is completed, the servo motor 1 drives the feeding arc gate 5 to rotate until the lower discharging port is completely blocked.

Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
