Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to an automatic ball feeder. Background Technology

[0002] Steel balls are widely used as key moving parts or sealing elements in many industrial products such as bearings, precision instruments, and valves. Efficiently and reliably delivering large quantities of bulk steel balls to designated workstations (such as assembly tanks, testing stations, or packaging containers) is a fundamental and crucial process on their production and assembly lines.

[0003] Currently, the common methods of steel ball feeding in the industry are mainly divided into the following two types: Manual feeding: Operators manually measure or pour steel balls. This method is not only inefficient and labor-intensive, but also difficult to precisely control the amount and pace of feeding. Human error can easily lead to overfeeding, underfeeding, or omissions, directly affecting product consistency and quality. Furthermore, scattered steel balls pose a safety hazard.

[0004] Mechanized automatic feeding: Some automated equipment already exists in the technology, such as the structure of using a vibratory feeder in conjunction with a direct vibration feeding track. Although such equipment reduces the burden of manpower to a certain extent, its working principle is usually to separate steel balls one by one in sequence. When the production cycle is very high, this intermittent working mode is difficult to meet the needs of high-speed and continuous feeding, becoming a bottleneck in the efficiency of the entire production line. In addition, the vibratory feeder and track are extremely sensitive to the size and roundness of the steel balls. When there are slight size deviations in the steel balls or they stick together slightly, jamming or bridging can easily occur at the track turning point or the separation mechanism, causing the equipment to stop and requiring manual intervention to troubleshoot, which affects the continuity and stability of production.

[0005] Therefore, there is an urgent need in this field for an automatic steel ball feeding device that can overcome the efficiency bottleneck of "separation one by one" and achieve high-speed, continuous and reliable operation. Utility Model Content

[0016] Preferably, the groove opening of the material guiding groove is provided with a rounded corner.

[0017] The technical effects and advantages of this utility model are as follows: 1. This utility model uses a barrel as the guiding structure for the balls. A rotatable hard brush is installed inside the barrel. The bottom plate at the bottom of the barrel has a discharge surface on its upper surface and a discharge hole in the middle of the discharge surface. During the rotation of the hard brush, the balls are pushed onto the discharge surface, which is set as an inclined surface. In this way, the balls roll down along the inclined discharge surface and pass through the discharge hole to complete the selection and feeding. Excess material will return to the non-discharge surface side. This technical solution uses the rolling characteristics of the balls to complete the feeding of the balls. Compared with the existing technology, it ensures continuous feeding of the balls while avoiding the problem of jamming. In addition, the balls only roll during the selection and feeding process and will not damage the surface of the balls, thus ensuring the continuity and stability of production. 2. This utility model uses a guide seat to guide the feeding of the balls. The guide seat can have one or more guide grooves inside, so as to realize feeding in one-to-one mode or feeding in multiple modes. When multiple guide grooves are set, the bottom ends of the multiple guide grooves are staggered. When multiple sets of balls are fed simultaneously, the multiple guide grooves guide one ball respectively. The inclined guide grooves can gather multiple balls towards the feeding port to facilitate the subsequent processing of the balls, thereby further improving the stability of production.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] This utility model provides, for example Figures 1 to 3 The automatic ball feeder shown is essentially an automatic ball feeder that uses the rolling of balls to select and feed materials. It includes a frame 1, a material cylinder 2 fixedly installed inside the frame 1, a base plate 3 fixedly installed at the bottom of the material cylinder 2, and a top cover 4 fixedly installed at the top of the material cylinder 2. A rotating shaft 5 is rotatably provided in the middle of the top cover 4 via a bearing. A hard brush 6 is fixedly installed at the bottom of the rotating shaft 5, and the bottom of the hard brush 6 is in contact with the upper surface of the base plate 3. A discharge surface 7 is provided at one end of the upper surface of the base plate 3. The discharge surface 7 can be set as an inclined surface with an upward slope. The discharge hole 9 is provided through the middle of the discharge surface 7. A discharge pipe 11 is provided at the bottom of the discharge hole 9. The discharge pipe 11 is connected to the guide groove 13 below. In order to ensure that the balls can roll and feed materials during the feeding process, the guide groove 13 can be set as an inclined surface. A guide groove 8 is provided at the top opening of the discharge hole 9. The opening of the guide groove 8 is rounded to prevent material from getting stuck at the opening of the guide groove 8. A drive motor 15 is fixedly installed on the upper surface of the top cover 4. The output shaft of the drive motor 15 is connected to the top of the rotating shaft 5. A movable cover plate 16 is rotatably provided on the outer side of the top cover 4 through a pin. A feed chute is provided through the middle of the movable cover plate 16. When it is necessary to clean the inside of the material cylinder 2, the movable cover plate 16 can be flipped to open it for easy maintenance of the equipment. The top of the inner part of the frame 1 is fixedly provided with a hopper 17, and the bottom of the outer side of the hopper 17 is fixedly provided with multiple feed pipes 18. The bottom ends of the multiple feed pipes 18 pass through the feed slots in the middle of multiple movable cover plates 16 and extend into the material cylinder 2. The hopper 17 is used for storing round balls, and the feed pipes 18 are used for feeding round balls.

[0027] Working principle of this utility model: When using this device, the beads to be fed are transferred into the hopper 17. The beads in the hopper 17 enter the cylinder 2 through the feeding pipe 18 and accumulate in the cylinder 2. At this time, the drive motor 15 is started, and the drive motor 15 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the hard brush 6 to rotate. The hard brush 6 pushes the beads inside the cylinder 2, causing the beads to roll on the upper surface of the bottom plate 3. After the beads are pushed to the discharge surface 7 by the hard brush 6, the beads roll along the discharge surface 7 under the action of pushing force and gravity. At this time, some beads roll into the guide groove 8 and then fall through the discharge hole 9 to complete the automatic selection and feeding of the beads. The beads that do not enter the guide groove 8 continue to roll along the discharge surface 7 and eventually stop at the other end of the discharge surface 7. The excess beads in the guide groove 8 are pushed out when the hard brush 6 rotates later and eventually stop at the other end of the discharge surface 7. With the continuous rotation of the hard brush 6, the beads circulate and roll in the cylinder 2 to complete the continuous feeding. It should be noted that before the equipment is running, a certain amount of beads should be put into the material cylinder 2 to ensure that beads enter the discharge hole 9 to complete the feeding when the hard brush 6 rotates once. It should be further noted that the drive motor 15, hopper 17, feeding pipe 18 and other structures designed in all embodiments of this technical solution adopt the corresponding structures in the prior art. Their models are not limited while ensuring the normal implementation of this technical solution. In addition, the diameter of the discharge hole 9 in this embodiment is slightly larger than the diameter of the ball to ensure the normal feeding of the ball. In the content and drawings of this embodiment, the number of discharge hole 9, guide hole 12 and guide groove 13 is one, so as to achieve the effect of feeding one ball at a time. Example 2

[0028] This embodiment is a supplement to Embodiment 1. Please refer to the appendix. Figure 1 , 2 Regarding points 4-6, considering that the actual feeding process involves the simultaneous feeding of multiple beads (one or more, such as two, three, or four beads), and that jamming can easily occur when multiple beads are fed simultaneously, this embodiment provides the following... Figures 4 to 6 The automatic ball feeder shown is essentially an automatic ball feeder capable of simultaneously feeding multiple sets of balls without jamming. This embodiment primarily uses the simultaneous feeding of four balls as an example; the feeding of more than one ball is adjusted according to the quantity and also falls within the protection scope of this solution. Specifically, it includes: A guide seat 10 is fixedly provided at the bottom end of the discharge pipe 11, and the guide seat 10 is fixedly provided on the lower surface of the base plate 3. The top end of the guide seat 10 is provided with a guide hole 12 corresponding to the discharge pipe 11. The inside of the guide seat 10 is provided with a guide groove 13 with an inclination. There are four discharge holes 9, four guide holes 12 and four guide grooves 13 (only in this example). The bottom ends of the guide grooves 13 are staggered. The top ends of the guide grooves 13 are respectively connected to the bottom ends of the guide holes 12, and the bottom ends of the guide grooves 13 are all connected to the top ends of the discharge pipe 11. Connecting ears 14 are fixedly installed on the top ends of both sides of the guide seat 10, and the connecting ears 14 are fixedly installed on the bottom end of the discharge pipe 11 by bolts. Since the guide groove 13 has an inclination, the four balls can gather towards the center when they roll down along the guide groove 13, which makes it convenient for the receiving tray 19 at the bottom to effectively receive the balls. Multiple receiving trays 19 are fixedly provided at the bottom of the inner side of the frame 1, and the multiple receiving trays 19 are located below the multiple material cylinders 2 respectively.

[0029] Working principle of this utility model: Based on the working principle of Embodiment 1, in this scheme, the ball falls into the guide hole 12 after passing through the discharge hole 9, and then enters the discharge pipe 11 under the guidance of the guide groove 13, and finally falls into the receiving tray 19 to wait for subsequent processing. During this process, since the guide groove 13 has an inclination, multiple balls can gather towards the center when rolling down along the guide groove 13. It should be noted that the receiving tray 19 can be connected to equipment such as a feeding machine and a packaging machine. It is used to guide the feeding of the balls. In all the attached drawings of this technical solution, there are four discharge holes 9, four guide holes 12 and four guide grooves 13, which realizes the protection scheme of discharging four balls at a time. In actual application, there is no limit to the number of discharge holes 9, four guide holes 12 and four guide grooves 13. It is possible to discharge multiple balls at a time. Based on this technical solution, this application has a protective effect for technical solutions with one, two, three or more discharge holes 9. When there is only one discharge hole 9, the balls passing through the discharge hole 9 can fall directly into the receiving tray 19. It should be further explained that a baffle or control valve or similar structure can be installed between the guide hole 12 and the discharge hole 9 to control the frequency of ball feeding. The baffle can be powered by a cylinder and can be controlled by horizontally sliding to separate the guide hole 12 and the discharge hole 9. The above structure and technical solution are common practices in this field and will not be elaborated here.

[0030] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
