[0002] A grinder is a mechanical device for grinding materials into fine powders or particles. There are various types of grinders. Among them, a vibratory grinder is a conventional grinding mechanical device, which is suitable for surface polishing, chamfering, deburring, polishing, and gloss finishing of small and medium-sized workpieces. The vibratory grinder applies abrasive particles to the surface of the workpiece through vibration force to achieve the purpose of grinding and polishing.

[0003] The main structure of the vibratory grinder includes a vibration source, grinding media, and a bowl-shaped working grinding disc. During grinding, the workpiece is placed in the working grinding disc, and abrasive particles are applied to the surface of the workpiece through vibration force to complete grinding and polishing. In the above operation, if the working grinding disc is sealed, it is not conducive to the feeding of the workpiece material, and if the working grinding disc is not sealed, the abrasive may burst out. In addition, when the workpiece material is put into the working grinding disc, although the material will move to a certain extent under the action of vibration force, the materials are still in a stacked state and cannot be separated, which is not conducive to block grinding. When the vibratory grinder is in use, there is a problem that there is no design that is conducive to feeding and diverting the stacked materials. Therefore, this application proposes a feeding port structure of a grinder. Summary of the Utility Model

[0024] Embodiment

[0025] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a feeding port structure of a grinding machine, including a feeding port assembly, including a feed hopper 1 and a material cover 2 communicating with the bottom end of the feed hopper 1. The feed hopper 1 and the material cover 2 cover the working plate of the grinding machine. The feed hopper 1 is a hollow structure with a wide upper part and a narrow lower part, which is conducive to feeding and can prevent abrasive from bursting out; a material distributing assembly, including a connecting ring 53 fitting the inner side wall of the material cover 2, a connecting column 52 with one end connected to the connecting ring 53, a material receiving plate 51 connected to the other end of the connecting ring 53, and a material distributing column 54 distributed at the center position of the material receiving plate 51. The connecting ring 53 and the material cover 2 are combined by conventional methods. Materials fall from the feed hopper 1, and the material distributing column 54 distributes the materials. The materials fall on the surface of the conical material receiving plate 51. The materials slide down under the action of gravity, and the materials fall from the circular edge position of the material receiving plate 51. The connecting column 52 distributes the materials, so that the material diversion effect is completed during feeding, avoiding uneven material distribution and resulting in a more concentrated material at a certain place; a material stirring assembly, including a fixed plate 61 installed on the material receiving plate 51, a limiting plate 64 attached to the opposite surface of the fixed plate 61, a damping backing plate 62 penetrating the fixed plate 61 and the limiting plate 64, a driving motor 63 installed at the center position of the damping backing plate 62, a connecting rod 3 connected to the output shaft of the driving motor 63, and disturbing columns 4 connected to both ends of the connecting rod 3. The fixed plate 61 is combined with the material receiving plate 51 and the damping backing plate 62 by conventional methods. The driving motor 63 drives the connecting rod 3 and the disturbing columns 4 to rotate. The disturbing columns 4 are located inside the working plate of the grinding machine. The disturbing columns 4 are inserted into the materials. As the disturbing columns 4 slowly rotate, the disturbing columns 4 disturb the piled materials, so that the materials can be turned over by a large angle, avoiding material accumulation and the overlapping part where grinding is not in place, and being conducive to full grinding.

[0026] In this embodiment, the centers of the feed hopper 1, the material cover 2, the material receiving plate 51, the connecting ring 53, and the material distributing column 54 are on the same axis. The outer surface of the material distributing column 54 is provided with uniformly distributed second protrusions 541. The material distributing column 54 and the second protrusions 541 distribute the material. The cross-section of the second protrusion 541 is in the shape of a semi-ellipse. The material receiving plate 51 is in the shape of a cone. The material falls on the sloping surface of the material receiving plate 51 and rolls down under the action of gravity. The bottom end of the material distributing column 54 is connected to the conical tip of the material receiving plate 51. The material distributing column 54 has the effect of distributing the material. The connecting column 52 is in a bent shape. The surface of the material receiving plate 51 is provided with diversion protrusions 511. The diversion protrusions 511 are in the shape of semi-ellipsoids. The diversion protrusions 511 have the effect of distributing the material rolling on the material receiving plate 51, achieving the purpose of material diversion.

[0027] In this embodiment, the fixing plate 61 has a "U"-shaped structure. A locking bolt connecting to the fixing plate 61 penetrates through the limiting plate 64. The limiting plate 64 is firmly connected to the fixing plate 61. A damping disc spring 7 is provided between the damping cushion plate 62 and the fixing plate 61. The damping cushion plate 62 is made of a rubber material with damping performance. The damping disc spring 7 has a damping effect and can buffer the vibration force received by the driving motor 63.

[0028] In this embodiment, the connecting rod 3 is in the shape of an open isosceles trapezoid, and the two ends of the connecting rod 3 are spherical. The disturbing column 4 has an inverted "Y"-shaped structure. The disturbing column 4 distributes the material. A vertical material distributing rod 41 is provided at one bifurcated end of the disturbing column 4. The outer surface of the material distributing rod 41 is provided with semi-spherical first protrusions 411. The material distributing rod 41 and the first protrusions 411 stir the material to prevent the material from piling up and overlapping, resulting in insufficient grinding.

[0029] The working principle and usage process of the present utility model:

[0030] When grinding a workpiece in the grinding disc of a vibration grinding machine, the material cover 2 is installed on the grinding disc. The feed hopper 1 and the material cover 2 cover the working disc of the grinding machine. The feed hopper 1 is a hollow structure with a wider top and a narrower bottom, which is conducive to feeding and can prevent abrasive from bursting out.

[0031] The material falls from the feed hopper 1. The material distributing column 54 distributes the material. The material falls on the sloping surface of the material receiving plate 51. The material slides down under the action of gravity. The diversion protrusions 511 distribute the material rolling on the material receiving plate 51.

[0032] The material falls from the circular edge position of the material receiving plate 51. The connecting column 52 distributes the material, achieving the effect of material diversion during feeding and avoiding uneven material distribution, resulting in a relatively concentrated material in a certain place.

[0033] The disturbing column 4 is located inside the working disk of the grinding machine. The disturbing column 4 is inserted into the interior of the material. The driving motor 63 drives the connecting rod 3 and the disturbing column 4 to rotate. As the disturbing column 4 slowly rotates, the disturbing column 4 disturbs the piled-up material, enabling it to greatly flip the angle of the material, avoiding the accumulation of the material and the overlapping parts where grinding is not in place, which is conducive to sufficient grinding.

[0034] In summary: The design of the vibrating grinding machine that is conducive to feeding and diverting the piled-up material. The feed hopper 1 is a hollow structure that is wider at the top and narrower at the bottom, which is conducive to feeding. The material slides on the surface of the sloping material receiving plate 51. The connecting column 52, the material dividing column 54, and the material diverting protrusions 511 divert the material, avoiding uneven distribution of the material. The driving motor 63 drives the connecting rod 3 and the disturbing column 4 to rotate and disturb the piled-up material, avoiding the accumulation of the material and the overlapping parts where grinding is not in place, which is conducive to sufficient grinding.

[0035] Although the embodiments of the present invention have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
