With the advancement of mechanical automation, these materials are often automatically fed via circular automatic feeding vibrating plates. Examples of pancake-like materials include round buttons, decorative hardware, metal gaskets in eyelet buckles, and plastic films (rubber rings). Because the materials spiral upward on the circular automatic feeding vibrating plate, long-term collisions can easily cause wear. This worn material residue can easily become stuck and difficult to clean. Vibrating plates are complex and costly, and they only handle loading and are unable to screen out defective or deformed materials. Summary of the Invention

[0027] The following embodiment is described using film feeding for an eyelet machine as an example. Of course, in some embodiments, this embodiment can also be used for feeding metal gaskets for eyelet machines, buttons for sewing machines, or hardware decoration processing. Film is a type of small pancake-shaped material.

[0028] like Figure 1-4As shown, this embodiment discloses a small, cake-shaped material feeding device, comprising a roller 4, a direct vibration mechanism 2, a conveyor platform 1, and a roller drive device 5. The roller 4 has an internal cavity 40 for accommodating films 3. An opening 41 is formed at one end of the roller 4, communicating with the internal cavity 40. The roller 5 drive device is connected to the roller 4 and drives its rotation. One end of the conveyor platform 1 extends into the internal cavity 40 through the opening 41. The conveyor platform 1 is provided with a conveying trough 10 and a material limiting member 11. The material limiting member 11 is located vertically above the conveying trough 10 and spaced from the bottom surface of the conveying trough 10 by a distance equal to the thickness of a film 3. A lifting portion 42 is provided within the internal cavity 40, which rotates and rises and falls accordingly. When the lifting portion 42 is at its lowest point, it stores films 3. When the lifting portion 42 is raised, the films 3 are allowed to fall freely, with at least a portion of the films 3 falling onto the conveyor platform 1. The direct vibration mechanism 2 is driven and connected to the conveying platform 1; the direct vibration mechanism 2 is a device that uses the vibration principle to convey or screen materials. The vibration principle includes electromagnetic vibration, air pressure vibration or mechanical vibration, etc., which belongs to the existing technology and its structure and principle will not be described in detail here.

[0029] The operating principle of this embodiment is that the roller 4 rotates via the roller drive device 5, while the lifting portion 42 is connected to the roller cavity 40. The rotation of the roller 40 drives the position of the lifting portion 42. As shown in the accompanying drawings, the films 3 tend to accumulate at a low position in the cavity 40 under the action of gravity, while the conveyor platform 1 is located above this low position. Therefore, the lifting portion 42 is used to bring the films 3 at the low position to a high position, allowing them to fall freely, and at least a portion of the films 3 can fall onto the conveyor platform 1, particularly into the conveyor trough 10. The conveyor platform 1 is connected to the direct vibration mechanism 2, allowing the conveyor platform 1, particularly the films 3 in the conveyor trough 10, to be transported outward from the cavity 40. More specifically, the width of the conveyor trough 10 is limited to allow only a single row of films 3 to pass through. A material limiter 11 is positioned vertically above the conveyor trough 10, and the height between the material limiter 11 and the conveyor trough 10 is limited to allow only a single film 3 to pass through, not two or more films stacked together.

[0030] More specifically, the roller drive device 5 can be a rotary motor. A rotary motor allows for intermittent feeding without causing wear to the rubber ring. More specifically, the feeder device of this embodiment can be mounted on the frame of the button sewing machine, or at least a portion of the feeder mechanism can be fixedly connected to the frame.

[0031] More specifically, the sidewalls of the inner cavity 40 are smooth, curved surfaces. This reduces friction between the film 3 and the sidewalls as it moves within the cavity, lowering the chance of wear or deformation. As shown in Figure 2 of the accompanying drawings, the sidewalls of the inner cavity 40 in this embodiment are cylindrical. The sidewalls of a cylinder are a type of curved surface.

[0032] More specifically, the lifting portion 42 is fixed on the wall surface of the inner cavity 40, and the lifting portion 42 is formed with a storage surface 421 extending toward the center of the inner cavity. The storage surface 421 is used to store films when it is at a low position. When the storage surface 421 moves to a high position, it is affected by the rotation of the roller 4, and the angle of the storage surface 421 is tilted, so that the film 3 can fall onto the conveying table 1 in the form of a free fall. More specifically, in order to make the storage effect of the storage surface 421 better, as shown in the accompanying drawings of the specification, one side of the storage surface 421 is in contact with the side wall surface of the inner cavity 40. Of course, in some embodiments, the lifting portion 42 can also be formed in the inner cavity 40 in a form integral with the roller 4, as a way to fix the lifting portion 42 to the wall surface of the inner cavity 40.

[0033] More specifically, the material limiting member 11 is located at the opening 41 or in the inner cavity 40; as shown in Figure 4 of the specification, the material limiting member 11 is a one-piece structure, and the sheet structure is provided with a curved surface 110. The structure is arranged on one side of the conveying platform 1, and the curved surface 110 spans the conveying trough 10 or the top of the connecting surface 12. The conveying trough 10 is in an open state at one end close to the material limiting member 11. The material limiting member 11 can also prevent some deformed films 3 with a thickness higher than the standard thickness, or defective films 3 whose vertical height changes due to deformation from passing through, and keep these defective products in the inner cavity 40, thereby improving the yield rate of the conveyed films 3. When a defective film 3 is blocked under the material limiting member, the film 3 moves in a curved direction along the curved surface 110 of the material limiting member 11 under the vibration of the direct vibration mechanism 2, and falls from the open end of the conveying trough 10 into the inner cavity 40.

[0034] More specifically, the end of the conveyor platform 1 extending into the inner cavity 40 is provided with a receiving surface 13 flush with the bottom surface of the conveyor trough 10. The width of the receiving surface 13 is greater than the width of the conveyor trough 10 and is used to collect a large number of films 3 that have fallen from the storage surface 421. A connecting surface 12 is connected between the receiving surface 13 and the bottom surface of the open end of the conveyor trough 10. The connecting surface 12 only allows a row of films 3 to pass through. In this embodiment, the receiving surface 13, the connecting surface 12, and the bottom surface of the conveyor trough 10 are integrally formed. In some embodiments, these surfaces can be distributed in different structural components. Under the action of the direct vibration mechanism 2, the films 3 on the receiving surface 13 enter the open end of the conveyor trough 10 from the connecting surface 12. The width of the connecting surface 12 ensures that the films 3 can only pass through in an orderly manner in a straight line. Those films 3 that are offset or parallel will fall from the side of the connecting surface 12 and return to the inner cavity 40.

[0035] More specifically, in order to ensure that the films 3 are arranged more neatly on the connecting surface 12, a guide surface 14 intersects one side of the connecting surface 12; the film 3 cannot cross the guide surface 14 and can only move forward along the guide surface 14. The other side of the connecting surface 12 is suspended. As shown in the accompanying drawings of the specification, the film 3 close to the other side of the connecting surface or the film 3 blocked by the material limiting member 11 can fall from the other side of the connecting surface 12 into the inner cavity 40. Of course, in some embodiments, the connecting surface 12 can also achieve the above function by providing a channel leading to the inner cavity 40. The side wall surface of the conveying trough 10 on the same side as the connecting surface 12 is connected to the guide surface 14. As shown in the accompanying drawings of the specification 4, the guide surface 14 not only intersects with one side of the connecting surface 12, but also extends to intersect with the same side of the receiving surface 13.

[0036] More specifically, the conveying platform 1 is provided with a shielding member 15 in the inner cavity 40; the shielding member 15 is formed with a shielding surface; the shielding surface extends to the opening 41, and is used to cover part of the structure of the conveying platform 1, to prevent the film 3 from falling into the conveying platform 1 except for the receiving surface 13, the conveying groove 10 and the connecting surface 12, and from leaking from the opening 41 under the drive of the direct vibration mechanism 2. As shown in Figure 3 of the specification, this embodiment discloses a shielding surface, including a B surface for vertical shielding and a C surface for horizontal shielding. The C surface is tilted downward to form an inclined surface, which facilitates the film 3 that falls from the storage surface 421 to slide from the C surface to the lower part of the inner cavity 40.

[0037] More specifically, the drum 4 is provided with a plurality of slag discharge holes 43, each with a smaller diameter than the rubber ring 3. Dust within the drum 4 or residue from the film 3 can fall out of the slag discharge holes 43 during the rotation of the drum 4, thus maintaining the cleanliness of the drum 4. The drum 4 is also provided with a feed port 44, which can be opened and closed. The feed port 44 is used to replenish the film 3 and monitor the condition of the drum 4.

[0038] More specifically, as shown in the appendix to the manual Figure 5-7As shown, the present invention discloses another embodiment, in which the sidewalls of the conveying trough 10 are formed by a left baffle 101 and a right baffle 102; the left baffle 101 and the right baffle 102 are arranged on the conveying trough 10 with an adjustable spacing. The bottom surface of the conveying trough 10 is a flat plate 103, and the left baffle 101 and the right baffle 102 are arranged on the flat plate 103, serving as the sidewalls of the conveying trough 10. The left baffle 101 and the right baffle 102 are arranged on the flat plate 103 with an adjustable spacing via waist-shaped holes 104 and fastening screws, thereby accommodating films 3 of different widths. More specifically, the left baffle 101 and the right baffle 102 form an arc-shaped limit 105 at one end away from the roller. When the film 3 moves to the limit 105, it cannot continue to move forward, and the bottom surface of the conveying trough 10, that is, the flat plate 103, is provided with a discharge hole 106 at the limit 105, and the film 3 falls into the discharge hole 106 on the limit.

[0039] More specifically, this embodiment features a pusher mechanism positioned vertically below the flat plate 103; the pusher mechanism comprises a pusher member that slides forward and backward and a drive device connected thereto. After the film 3 drops from the discharge hole 106, it is pushed forward by the pusher member to the buttoning station. Those skilled in the art will readily appreciate the various modifications and variations of the technical solutions and concepts described above, all of which fall within the scope of protection of the present utility model.
