Description

Technical Field

[0001] This utility model relates to the technical field of ceramic tile polishing equipment, and specifically to a polishing grinding head structure. Background Technology

[0002] Polishing equipment is needed to polish the surface of various slab materials such as granite, marble, microcrystalline glass, and ceramic tiles.

[0003] Traditional polishing machines use a oscillating, circular rotation of the grinding head to polish the surface of the material through surface contact. The rotation direction of this type of flat polishing grinding head is the same as the rotation direction of the motor output shaft. When this type of flat polishing grinding head rotates with the large grinding disc and applies the same pressure to the surface of the material, the abrasive layer of the grinding head is worn out in large quantities, and the maximum speed can only reach 800 rpm, resulting in low polishing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a polishing head structure that addresses the problems of high abrasive layer wear and low polishing efficiency caused by low rotation speed in existing grinding heads.

[0005] To achieve the above objectives, this utility model provides a polishing head structure, comprising: a drive motor, the output shaft of which is connected to a reducer; a grinding disc, the axial center hole of which is connected to the output shaft of the reducer on one side, the central axis of which is perpendicular to the central axis of the drive motor; and polishing abrasive, which is disposed on the outer peripheral surface of the grinding disc, the outer peripheral surface of which has a circular outline.

[0006] Furthermore, the polishing abrasive is provided in multiple portions, which are arranged around the outer peripheral surface of the grinding disc and are detachably connected to the grinding disc.

[0007] Furthermore, the outer peripheral surface of the grinding disc is provided with a plurality of insertion slots, and one end face of the polishing abrasive is provided with an insertion block that mates with the insertion slots.

[0008] Furthermore, the end face of the grinding disc is provided with a retaining ring for blocking the insert block.

[0009] Furthermore, the vertical cross-section of both the insertion slot and the insertion block is rectangular or trapezoidal.

[0010] Furthermore, the grinding disc includes a coupling sleeve and an abrasive roller. The coupling sleeve is sleeved and connected to the output shaft end on one side of the reducer. The abrasive roller is sleeved on the coupling sleeve, and the polishing abrasive is detachably arranged around the outer circumferential surface of the abrasive roller.

[0011] Furthermore, the coupling sleeve is frustum-shaped, and the abrasive roller has a frustum-shaped hole at its center that is compatible with the coupling sleeve.

[0012] Furthermore, a pressure cap is provided at one end of the coupling sleeve and the abrasive sleeve, and the pressure cap is fastened to the output shaft on one side of the reducer by screws.

[0013] The polishing head structure provided by this utility model, compared with the prior art, has a reducer connected to the output shaft end of the drive motor, and the axial center hole of the grinding disc is connected to the output shaft end of the reducer on one side. The central axis of the grinding disc is set perpendicular to the central axis of the drive motor, so that the grinding disc and the drive motor are set in an L-shape, so that the grinding disc rolls and rotates at the output shaft end of the reducer. By converting the transmission ratio, the rotation speed of the grinding disc can be effectively increased, thus improving the polishing efficiency. In addition, the outer circumferential surface of the polishing abrasive is set on the outer circumferential surface of the grinding disc, so that the material to be polished is linearly contacted during polishing, effectively reducing the wear of the polishing abrasive and saving costs.

[0021] The present invention will be described in detail below with reference to specific embodiments.

[0022] In this utility model, when directional terms appear, they are used to facilitate the description of this utility model and simplify the description, rather than indicating or implying that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this utility model.

[0023] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figures 1 to 3 As shown, a polishing head structure includes a drive motor 10, a grinding disc 20, and a polishing abrasive 30.

[0025] The output shaft end of the drive motor 10 is connected to the reducer 11. The axial center hole of the grinding disc 20 is connected to the output shaft end of the reducer 11 on one side. The central axis of the grinding disc 20 is set perpendicular to the central axis of the drive motor 10. The polishing abrasive 30 is set on the outer peripheral surface of the grinding disc 20. The outline of the outer peripheral surface of the polishing abrasive 30 is circular.

[0026] In practical implementation, the central axis of the grinding disc 20 is set perpendicular to the central axis of the drive motor 10, so that the grinding disc 20 and the drive motor 10 are set in an L-shape. This allows the grinding disc 20 to roll and rotate at the output shaft end of the reducer 11. By converting the transmission ratio, the rotational speed of the grinding disc 20 can be effectively increased, thereby improving the polishing efficiency of a single polishing head. Furthermore, the outer circumferential surface of the polishing abrasive 30 is set in a circular shape on the outer circumferential surface of the grinding disc 20, thus achieving linear contact with the material to be polished during polishing, effectively reducing the wear of the polishing abrasive 30 and saving costs.

[0027] In this embodiment, multiple polishing abrasives 30 are provided, and the multiple polishing abrasives 30 are arranged around the outer peripheral surface of the grinding disk 20 and are detachably connected to the grinding disk 20.

[0028] In practice, the polishing abrasive 30 adopts a split structure and is detachably connected to the grinding disc 20, which facilitates timely replacement of the polishing abrasive 30 after it is worn out.

[0029] Specifically, the outer circumferential surface of the grinding disc 20 is provided with multiple insertion slots 23, and one end face of the polishing abrasive 30 is provided with an insertion block 31 that mates with the insertion slots 23. The polishing abrasive 30 is detached from the insertion slots 23 on the grinding disc 20 through the insertion block 31. The vertical cross-sections of the insertion slots 23 and the insertion block 31 are both rectangular or trapezoidal to enhance the tightness of the connection between them.

[0030] In this embodiment, the end face of the grinding disc 20 is provided with a retaining ring (not shown in the view) for blocking the insert 31, to prevent the polishing abrasive 30 from loosening and falling off the grinding disc 20 when the grinding disc 20 is rotating at high speed.

[0031] In this embodiment, the grinding disc 20 includes a coupling sleeve 21 and an abrasive roller 22. The coupling sleeve 21 is sleeved and connected to the output shaft end on one side of the reducer 11. The abrasive roller 22 is sleeved on the coupling sleeve 21. The polishing abrasive 30 is detachably arranged around the outer circumferential surface of the abrasive roller 22.

[0032] In practice, one end of the coupling sleeve 21 and the abrasive sleeve is provided with a pressure cap 24, and the pressure cap 24 is fastened to the output shaft on one side of the reducer 11 by screws.

[0033] The coupling sleeve 21 is frustum-shaped, and the abrasive roller 22 has a frustum-shaped hole in the center that matches the coupling sleeve 21. Through the fit between the conical surfaces, the abrasive roller 22 and the coupling sleeve 21 can be connected more securely, preventing loosening during high-speed rolling rotation.

[0034] Where there is no conflict, the above embodiments and features can be combined with each other.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
