Description

Technical Field

[0001] The invention relates to a component of a glass edge grinding machine, in particular to an adjustable feeding mechanism of the glass edge grinding machine. Background Art

[0002] Glass edge grinding machine is a commonly used post-processing equipment for glass plates. It grinds the edges and depressions at the edges of the glass to make the edges of the glass plates straight and smooth.

[0003] Since glass is rigid and brittle, it cannot be processed with too much grinding amount when grinding the glass, but must be completed by multiple grinding. Chinese patent document CN206425931U discloses a high-speed energy-saving glass double-sided edge grinding machine, which grinds the edge of the glass with different feed amounts by setting at least two sets of grinding head motors on the fixed edge and the moving edge respectively. Chinese patent document CN202225042U discloses a multi-stage straight-line glass edge grinding machine, which also uses edge grinding motors with different feed amounts to perform multi-stage grinding on the glass.

[0004] Although the above-mentioned glass edge grinding machine can perform multi-stage grinding on the edge of the glass through different feed amounts, it still has two major technical defects. First, the grinding wheels with different feed amounts are driven by different grinding head motors, and the grinding wheels cannot achieve synchronous rotation at all. When the glass switches between the two motors, the grinding resistance will be different due to the different rotation speeds, which will cause the glass to vibrate during transportation. In severe cases, the glass will burst due to the excessive change in grinding resistance. Second, in the above multi-stage grinding process, due to the need to retain a gap between the grinding wheel diameter and the grinding head motor, the graded length of the glass edge is at least greater than the grinding wheel diameter, thereby increasing the stroke of the glass in the entire grinding process in disguise. In addition to greatly reducing the processing efficiency of glass grinding, it will also greatly increase the occupied volume of the glass edge grinding machine. Summary of the invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The applicant hereby emphasizes that the following embodiments are one or several examples that can implement the technical solutions of the present invention, obtain corresponding technical effects, and solve corresponding technical problems, but it does not mean that the protection scope of the technical solutions only includes the following embodiments.

[0026] According to Figures 1 to 8As shown in the figure, the adjustable feeding mechanism of the glass edge grinding machine of the present invention mainly includes a base 1, a mounting seat 2 and an edge grinding assembly. The base 1 is located on the frame of the edge grinding machine and is fixed to the frame. The mounting seat 2 is arranged on the base 1 and can slide back and forth on the base 1 to adjust the distance between the edge grinding assembly and the edge of the glass. The edge grinding assembly is arranged on the mounting seat 2 and is used for grinding the edge of the passing glass. The edge grinding assembly includes a driving motor 31, a housing 32, an outer driving shaft 33 and an inner driving shaft 34. The driving motor 31 and the housing 32 are both arranged on the mounting seat 2 and are both fixed to the mounting seat 2. The outer driving shaft 33 is located inside the housing 32. The edge grinding assembly includes a driving motor 31, a housing 32, an outer driving shaft 33, an outer grinding head, an inner driving shaft 34, an inner grinding head and a first pushing device. The driving motor 31 and the housing 32 are arranged on the mounting seat 2 and are fixed to the mounting seat 2. The outer driving shaft 33 is arranged inside the housing 32 and is connected to the driving motor 31. In the present invention, the output shaft of the driving motor 31 can be connected to the outer surface of the outer driving shaft 33 through a belt or a chain, so that the outer driving shaft 33 rotates around its axis inside the housing 32 under the drive of the driving motor 31. The outer grinding head is located outside the housing 32, and one end of the outer driving shaft 33 extends out of the housing 32 and is fixed to the outer grinding head. The driving motor 31 drives the outer driving shaft 33 to make the outer grinding head rotate synchronously and grind the edge of the passing glass. The inner driving shaft 34 is arranged inside the outer driving shaft 33, is coaxially arranged with the outer driving shaft 33 and can rotate synchronously with the outer driving shaft 33. The inner grinding head is fixed to the end of the inner driving shaft 34, is located on the same side as the outer grinding head and rotates synchronously with the outer grinding head. A first pushing device is also arranged on the mounting seat 2. The first pushing device includes a pushing cylinder 43 and a pushing bearing 44. The pushing cylinder 43 is located on the mounting seat 2 and is fixed to the mounting seat 2. The pushing bearing 44 is arranged on the pushing cylinder 43, and its inner ring is fixed to the inner driving shaft 34. The pushing cylinder 43 can drive the inner driving shaft 34 to move back and forth along its axis without affecting the normal rotation of the inner driving shaft 34, so as to realize that the inner grinding head forms a telescopic structure on the axis of the outer grinding head, and when the inner grinding head extends out of the end face of the outer grinding head, the two perform grinding processing on the passing glass side surface with two feeding amounts within a distance of a radius difference. For the setting and installation of the adjustable feeding mechanism of the present invention on the frame, those skilled in the art can refer to the setting or installation methods of the grinding mechanism in Chinese patent document CN202225042U, the grinding head motor in Chinese patent document CN206425931U, the edge grinding device in Chinese patent document CN110370145A, etc., and will not be elaborated here. In addition, the adjustable feeding mechanism of the present invention is electrically connected to the circuit controller on the frame to control its actions.

[0027] In one embodiment of the present invention, the pushing cylinder 43 can be an oil cylinder or a pneumatic cylinder. The cylinder body of the oil cylinder or pneumatic cylinder is fixedly connected to the mounting seat 2, and its piston rod is fixedly connected to the outer edge of the pushing bearing 44.

[0028] In one embodiment of the present invention, a first pushing motor 41 is provided on the mounting seat 2, and a first pushing screw 42 is provided on the first pushing motor 41. The first pushing motor 41 is fixedly connected to the mounting seat 2, and the first pushing screw 42 is connected to the first pushing motor 41 and rotates driven by the first pushing motor 41. In this embodiment, a first bevel gear set 48 can be provided between the first pushing motor 41 and the first pushing screw 42, and the reduction drive between the first pushing motor 41 and the first pushing screw 42 is realized through the diameter difference of the gears of the first bevel gear set 48, improving the rotation stability of the first pushing screw 42 and increasing its torque. A first adjusting rod 49 meshing with the first bevel gear set 48 can also be provided on the side of the first bevel gear set 48, and the manual fine adjustment of the first pushing screw 42 is realized through the meshing of the bevel gears. The pushing cylinder 43 is connected to the first pushing screw 42 in a threaded engagement manner and can reciprocate along its axis when the first pushing screw 42 rotates. There is also a pushing bearing 44 in the pushing cylinder 43. The outer ring of the pushing bearing 44 is fixedly connected to the pushing cylinder 43, and its inner ring is fixedly connected to the inner drive shaft 34. Therefore, when the pushing cylinder 43 moves along its axis, it does not affect the normal rotation of the inner drive shaft 34, realizing the complete separation of the rotation and axial movement of the inner drive shaft 34.

[0029] In one embodiment of the present invention, the mounting seat 2 also has a first positioning sleeve 45. The first positioning sleeve 45 is fixedly connected to the mounting seat 2 and sleeved with the pushing cylinder 43 to prevent the pushing cylinder 43 from rotating when the inner drive shaft 34 rotates.

[0030] In another embodiment, the outer surface of the pushing cylinder 43 can be in a polygonal shape, and the inner surface of the first positioning sleeve 45 can also be in a polygonal shape. The outer surface of the pushing cylinder 43 and the inner surface of the first positioning sleeve 45 can be matched to realize their mutual fixation. In this embodiment, the polygon can be a triangle, a quadrilateral, a pentagon or a hexagon, and those skilled in the art can select according to actual needs.

[0031] In another embodiment, the pushing cylinder 43 is provided with a first positioning sliding groove 46 which is arranged along the axial direction of the pushing cylinder 43 and can be directly formed on the outer surface of the pushing cylinder 43. The first positioning sleeve 45 is internally provided with a first positioning sliding block 47 which is also arranged along the axial direction of the first positioning sleeve 45 and can be directly machined on the inner surface of the first positioning sleeve 45. The first positioning sliding block 47 and the first positioning sliding groove 46 are arranged in the same direction and are connected in a matching manner. Besides guiding the positioning sleeve during its axial movement, it also prevents the positioning sleeve from rotating under the driving force transmitted through the pushing bearing 44 when the inner driving shaft 34 rotates, further improving the stability and reliability of the independent operation of the pushing cylinder 43 and the inner driving shaft 34.

[0032] In another embodiment of the present invention, the inner driving shaft 34 is provided with a second positioning groove which is arranged along the axial direction of the inner driving shaft 34 and can be directly machined on the outer surface of the inner driving shaft 34. The outer driving shaft 33 is internally provided with a second positioning sliding block 36 which is also arranged along the axial direction of the outer driving shaft 33 and can be directly machined on the inner surface of the outer driving shaft 33. The second positioning sliding block 36 and the second positioning sliding groove 35 are arranged in the same direction and are connected in a matching manner. Besides guiding the inner driving shaft 34 during its axial movement, it also enables the outer driving shaft 33 to drive the inner driving shaft 34 to rotate synchronously when the driving motor 31 is operating.

[0033] In another embodiment of the present invention, the outer surface of the inner driving shaft 34 can adopt a polygonal shape, and the inner surface of the outer driving shaft 33 can also adopt a polygonal shape. The outer surface of the inner driving shaft 34 and the inner surface of the outer driving shaft 33 can be matched to achieve mutual fixation. In this embodiment, the polygon can be a triangle, a quadrilateral, a pentagon or a hexagon, and those skilled in the art can select according to actual needs.

[0034] In another embodiment of the present invention, the outer grinding head includes an outer grinding seat 51 and an outer grinding portion 52. The outer grinding seat 51 is located at the end of the outer driving shaft 33 and is fixed to the driving shaft. The outer grinding portion 52 is located outside the housing 32 and is fixed to the outer grinding seat 51. The outer grinding seat 51 is also provided with a sealing platform 53 which is located on the side of the outer grinding seat 51 corresponding to the housing 32 and is inclined outward. And the side of the housing 32 corresponding to the outer grinding seat 51 is provided with an inclined portion 54 which is inclined inward and matches the sealing platform 53 and can be inserted into the sealing platform 53. There is a certain gap between the inclined portion 54 and the sealing platform 53, so that when the outer grinding seat 51 and the outer driving shaft 33 rotate, the grinding water can be discharged from the gap by the centrifugal force of rotation, avoiding the situation of water accumulation inside the outer grinding head.

[0035] In another embodiment of the present invention, the internal grinding head includes an internal grinding base 61 and an internal grinding portion 62. The grinding base 1 is located at the end of the internal drive shaft 34 and is fixedly connected thereto. The internal grinding portion 62 is also located outside the housing 32, on the same side as the external grinding portion 52, and is fixedly connected to the internal grinding base 61. The internal grinding base 61 further has a first seal 63, which is located between the internal grinding base 61 and the inner side of the external grinding head, specifically between the outer surface of the internal grinding base 61 and the inner surface of the external grinding base 51. The provision of the first seal 63 can ensure that the grinding water does not enter the connection structure of the external drive shaft 33 and the internal drive shaft 34 from the end faces of the external grinding head and the internal grinding head, effectively preventing the accumulation of grinding water and the corrosion of the external drive shaft 33 and the internal drive shaft 34.

[0036] In another embodiment of the present invention, the external drive shaft 33 further has a second seal 55. The second seal 55 corresponds to the positions of the housing 32 and the internal drive shaft 34 respectively, to prevent the grinding water from leaking from the gap between the external grinding head and the housing 32 into the interiors of the external drive shaft 33 and the internal drive shaft 34, further enhancing the working stability of the external drive shaft 33 and the internal drive shaft 34.

[0037] In the present invention, through the centrifugal drainage effect between the inclined portion 54 and the sealing table 53, and the sealing protection of the external drive shaft 33 and the internal drive shaft 34 by the first seal 63 and the second seal 55, in addition to greatly reducing the infiltration amount of the grinding water, the external drive shaft 33 and the internal drive shaft 34 also form a closed space isolated from the outside world. The above-mentioned drainage effect and sealing protection can prevent the external drive shaft 33, the internal drive shaft 34 and the first pushing device from rusting after long-term use of the glass edging machine, and effectively reduce the lubricating grease of the connecting components in the external drive shaft 33, the internal drive shaft 34 and the first pushing device being carried away when the grinding water flows, enhancing the working stability and reliability of the above components.

[0038] In another embodiment of the present invention, a second pushing device is further provided on the base 1. The second pushing device can push the mounting seat 2 to move back and forth on the base 1, so as to drive the feeding mechanism to approach the path where the glass passes through.

[0039] In another embodiment, the second pushing device includes a second pushing motor 71, a second pushing screw 72, and a pushing block 73. The second pushing motor 71 is located on the mounting base 2 and is fixed to the mounting base 2. The second pushing screw 72 is connected to the second pushing motor 71 and rotates driven by the second pushing motor 71. The pushing block 73 is located on the base 1 and is fixed to the base 1. It is threadedly connected to the second pushing screw 72 to drive the mounting base 2 to move on the base 1 when the second pushing screw 72 rotates. In this embodiment, the same transmission structure as that between the first pushing motor 41 and the first pushing screw 42 can be adopted, that is, a second bevel gear set 74 can be provided between the second pushing motor 71 and the second pushing screw 72, and the reduction transmission between the second pushing motor 71 and the second pushing screw 72 is achieved through the diameter difference of the gears of the second bevel gear set 74. In addition, a second adjusting rod 75 meshing with the side of the second bevel gear set 74 can be provided, and the manual fine adjustment of the second pushing screw 72 is achieved through the meshing of the bevel gears.

[0040] In another embodiment, the second pushing device can adopt an oil cylinder or a cylinder. The cylinder body of the cylinder or the oil cylinder is fixedly connected to the mounting base 2, and its piston rod is fixedly connected to the base 1.

[0041] In another embodiment, a matching slide rail 76 is further provided between the base 1 and the mounting base 2. The slide rail 76 is arranged along the mutual movement direction between the base 1 and the mounting base 2 to improve the stability of the mounting base 2 sliding back and forth on the base 1.
