Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically to automatic feeding devices. Background Technology

[0002] In modern industrial production, automatic feeding devices are widely used in chemical, food, and building materials industries as key equipment for realizing automated material handling.

[0003] Currently, traditional automatic feeding devices mostly adopt a single auger conveyor structure. However, the materials produced by machinery include various forms such as metal powder, viscous lubricant, and lumpy billets, which are prone to bridging and accumulation in the material cylinder, resulting in poor material feeding or even production interruption. Although some existing devices have added a dispersing structure to improve the material agglomeration effect, most of them rely on mixing rollers for mixing and dispersing. Since the mixing rollers usually move along a straight line or fixed trajectory, it is easy to form a dispersing dead zone in the material cylinder, resulting in poor material feeding. Therefore, this utility model proposes an automatic feeding device to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, such as dead zones in mixing and poor adaptability to various material forms, a planetary mechanism and a drive mechanism are set up to achieve the rotation of the mixing rod on its own axis and revolution around the sun, thus avoiding dead zones in the mixing process. The auger blades and mixing rod are synchronously controlled by gear transmission to prevent the conveying and mixing processes from becoming disconnected, thus adapting to various material forms.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: It includes a feeding cylinder with an open upper end and a cover plate at the open end. An inlet pipe and a outlet pipe are fixedly connected to the side wall and lower end of the feeding cylinder, respectively. The bottom of the feeding cylinder is inclined, with the inclined end extending to the outlet pipe opening. An auger blade is rotatably connected inside the outlet pipe. A stirring rod is rotatably connected inside the feeding cylinder. Multiple sets of stirring rollers are distributed circumferentially on the outer wall of the stirring rod. A planetary mechanism is installed on the outer wall of the cover plate; a driving mechanism is also installed on the outer wall of the cover plate.

[0008] The planetary mechanism is used to drive the stirring rod to revolve around the axis of the feeding cylinder;

[0009] The drive mechanism is used to drive the stirring rod to rotate;

[0010] Preferably, the planetary mechanism includes a second gear and a first gear rotatably connected to the lower end face of the cover plate. The first gear and the second gear mesh with each other. A rotating rod is coaxially fixedly connected to the lower end face of the second gear, and the end of the rotating rod is coaxially fixedly connected to the auger blade. The first gear is coaxially fixedly connected to the stirring rod.

[0011] Preferably, the driving mechanism includes an annular rack fixedly connected to the lower end face of the cover plate, the gear meshing with the annular rack, and a ring frame fixedly connected to the top of the inner side of the cover plate.

[0012] Preferably, the outer wall of the ring frame is symmetrically provided with sliding grooves, and two sets of sliding grooves are slidably connected to a sliding seat, which is rotatably connected to a gear.

[0013] Preferably, the lower end of the slide block is rotatably connected to two sets of balls, and both sets of balls are in contact with the bottom of the slide groove.

[0014] Preferably, a servo motor is fixedly connected to the end face of the cover plate, and the end of the output shaft of the servo motor is fixedly connected to the gear two coaxially.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides an automatic feeding device, which has the following beneficial effects:

[0017] Through the cooperation of components such as stirring rod and stirring roller, the stirring rod drives the stirring roller to perform a compound motion of rotation and revolution under the drive of planetary mechanism. This can cover the inside of the feeding cylinder. Compared with the traditional linear trajectory dispersing, it completely eliminates the blind spot of dispersing. Even when facing materials that require precise mixing, such as metal powder and additives, it can achieve full dispersing. Attached Figure Description

[0025] This utility model provides a technical solution for an automatic feeding device:

[0026] Please see Figure 1-5 An automatic feeding device includes a feeding cylinder 1 with an open top and a cover plate 2 at the open end. A feed pipe 4 and a discharge pipe 5 are fixedly connected to the side wall and lower end of the feeding cylinder 1, respectively. The bottom of the feeding cylinder 1 is inclined, and the inclined end extends to the opening of the discharge pipe 5. An auger blade 7 is rotatably connected inside the discharge pipe 5. A stirring rod 8 is rotatably connected inside the feeding cylinder 1. Multiple sets of stirring rollers 9 are distributed around the outer wall of the stirring rod 8. A planetary mechanism is installed on the outer wall of the cover plate 2. A drive mechanism is installed on the outer wall of the cover plate 2.

[0027] The planetary mechanism is used to drive the stirring rod 8 to revolve around the axis of the feeding cylinder 1;

[0028] The drive mechanism is used to drive the stirring rod 8 to rotate;

[0029] Furthermore, the coordinated arrangement of the planetary mechanism and the drive mechanism allows the stirring rod 8 to revolve around the axis of the feeding cylinder 1 while rotating on its own axis, forming a planetary dispersing trajectory, effectively eliminating the dispersing dead angles caused by the linear motion of the traditional stirring roller.

[0030] The planetary mechanism includes a second gear 14 and a first gear 13 rotatably connected to the lower end face of the cover plate 2. The first gear 13 meshes with the second gear 14. A rotating rod 6 is coaxially fixedly connected to the lower end face of the second gear 14, and the end of the rotating rod 6 is coaxially fixedly connected to the auger blade 7. The first gear 13 is coaxially fixedly connected to the stirring rod 8.

[0031] Furthermore, the meshing transmission of gear 13 and gear 2 14 synchronously distributes the power of servo motor 3 to auger blade 7 and stirring rod 8, realizing the linkage control of conveying and dispersing functions.

[0032] The drive mechanism includes an annular rack 10 fixedly connected to the lower end face of the cover plate 2, a gear 13 meshing with the annular rack 10, and a ring frame 11 fixedly connected to the top of the inner side of the cover plate 2.

[0033] Furthermore, the meshing of the annular rack 10 with the gear 13 ensures that the stirring rod 8 maintains stable rotation during its revolution.

[0034] The outer wall of the ring frame 11 is symmetrically provided with sliding grooves 12. A sliding seat 15 is slidably connected in both sets of sliding grooves 12. The sliding seat 15 is rotatably connected to the gear 13. Two sets of balls 16 are rotatably connected to the lower end of the sliding seat 15. Both sets of balls 16 are in contact with the bottom of the sliding groove 12.

[0035] Furthermore, the sliding fit between the slide block 15 and the slide groove 12 provides stable support for the gear 13 while allowing it to revolve around the axis of the feeding cylinder 1, ensuring smooth operation of the planetary mechanism. The setting of the ball bearing 16 converts the sliding friction between the slide block 15 and the slide groove 12 into rolling friction, thereby reducing the revolution resistance of the stirring rod 8.

[0036] A servo motor 3 is fixedly connected to the end face of the cover plate 2, and the end of the output shaft of the servo motor 3 is fixedly connected to the gear 14 on the same axis.

[0037] In practical use, the working principle of this utility model is as follows:

[0038] Material enters feeding cylinder 1 through feeding pipe 4. When feeding is required, the operator starts the servo motor 3 on the end face of cover plate 2, and its output shaft drives gear 14 to rotate coaxially. Gear 14 meshes with gear 13, which drives the rotating rod 6 to rotate, causing the auger blades 7 in the discharge pipe 5 to start rotating, pushing the material at the inclined bottom of feeding cylinder 1 out along the discharge pipe 5.

[0039] On the other hand, gear 13, driven by gear 2 14, rolls along the annular rack 10 fixed to the lower end face of cover plate 2. Since gear 13 is coaxially fixedly connected to stirring rod 8, and slide block 15 slides in the groove 12 of ring frame 11 through ball bearing 16, stirring rod 8 rotates on its own axis and revolves around the axis of feeding cylinder 1. The stirring roller 9 on its outer wall thus forms a planetary dispersion trajectory of rotation + revolution.

[0040] For materials that are prone to agglomeration, such as metal powder, the composite motion of the stirring roller 9 can penetrate into the four corner areas of the feeding cylinder 1 to break up the bridging and accumulation caused by electrostatic adsorption or particle friction. During the entire feeding process, the servo motor 3 can precisely adjust the speed according to the material characteristics and synchronously control the conveying speed of the auger blade 7 and the dispersing frequency of the stirring rod 8 through the gear transmission ratio to achieve dynamic coordination of conveying and dispersing.

[0041] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
