Description

A multi-directional grinding machine for glass finishing

Technical Field

The invention relates to the technical field of grinding, and in particular to a multi-directional grinding machine for glass finishing.

Background technique

In the glass finishing process, the multi-directional grinder is an indispensable finishing equipment. It is specially designed to achieve all-round fine processing of glass panels. This type of machine can accurately chamfer and grind the four sides and even the edges of the glass to ensure that each edge achieves a high degree of smoothness and brightness.

When finishing glass, it is necessary to grind the four sides first and then chamfer. These two steps usually require different grinding tools to complete. Due to differences in process requirements, when transitioning from four-side grinding to chamfer grinding, the grinding tools need to be replaced or the angle adjusted. There will be a time difference in the operation conversion in between. If the angle is not adjusted properly, it may cause uneven grinding lines, uneven edges, or defects such as over-grinding and scratches, which will affect the appearance quality and function of the glass products.

Based on the above situation, the present invention provides a multi-directional grinder for glass finishing.

Detailed ways

The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

Embodiment 1: A multi-directional grinding machine for glass finishing, in conjunction with Figures 1 to 6, comprises a grinding frame 1, a placing cylinder 2 is slidably connected to the middle of the grinding frame 1 along the up-down direction, four turntables 3 are rotatably connected to the upper part of the grinding frame 1, and the four turntables 3 are driven by belts 4, the grinding frame 1 is fixedly connected to two motors 5, the output shafts of the motors 5 are fixedly connected to the adjacent turntables 3, the grinding frame 1 is annularly slidably connected to a mounting frame 6, and a first grinding tool for grinding the glass is slidably connected to the middle of the mounting frame 6 along the left-right direction 7, the middle part of the mounting frame 6 is slidably connected with a slider 701 for limiting the first grinder 7 along the up-down direction, the slider 701 is pressed and matched with the first grinder 7, the mounting frame 6 is slidably connected with a second grinder 8 symmetrically distributed along the up-down direction of the mounting frame 6, the second grinder 8 is used to chamfer the glass, and a guide frame 9 is slidably connected between the second grinder 8 and the first grinder 7, and a guide plate 10 is slidably connected to the left front side of the grinding frame 1 along the front-back direction, and the guide plate 10 has an X-shaped guide groove for guiding the first grinder 7.

When using the grinding machine to grind glass in multiple directions, first, the glass to be ground is pushed from front to back to the top of the placement tube 2 by the conveying device, and then the motor 5 is started, and the output shaft of the motor 5 drives the belt 4 to start running through the turntable 3, and the belt 4 drives the mounting frame 6 to rotate clockwise, so that the first grinding tool 7, the second grinding tool 8 and the guide frame 9 rotate clockwise synchronously;

In the above process, the first grinder 7 will move to the right when passing through the X-shaped guide groove of the guide plate 10, thereby squeezing the upper guide frame 9 to move upward and the lower guide frame 9 to move downward. When the upper guide frame 9 moves upward, it squeezes the upper second grinder 8 to slide obliquely upward, and when the lower guide frame 9 moves downward, it squeezes the lower second grinder 8 to slide obliquely downward. In this way, the first grinder 7 extends out of the mounting frame 6 to the right, and the second grinder 8 is retracted into the mounting frame 6. When the first grinder 7 moves to disengage from the guide groove of the guide plate 10, at this time, the second grinder 8 is completely retracted into the mounting frame 6, and the first grinder 7 is completely extended to the right and contacts the side of the glass. The mounting frame 6 drives the first grinder 7 to circle clockwise for one circle and then returns to the initial position, so that the first grinder 7 completes circular grinding around the side of the glass, thereby realizing multi-directional edge grinding operation on the glass.

When the first grinding tool 7 slides to the right along the mounting frame 6, it will first push the slider 701 upwards, and then the slider 701 will slide downwards to reset under the action of gravity, and then push the slider 701 upwards again when it is about to be fully extended. When the first grinding tool 7 is fully extended to the right, the slider 701 will slide downwards again under the action of gravity to clamp the first grinding tool 7, so as to prevent the first grinding tool 7 from sliding to the left at will during edge grinding;

Then, when the first grinder 7 passes through the X-shaped guide groove of the guide plate 10 again, it will move to the left, thereby squeezing the upper guide frame 9 to move downward, and the lower guide frame 9 to move upward. When the upper guide frame 9 moves downward, it squeezes the upper second grinder 8 to slide obliquely downward, and when the lower guide frame 9 moves upward, it squeezes the lower second grinder 8 to slide obliquely upward. In this way, the first grinder 7 is retracted into the mounting frame 6 to the left, and the second grinder 8 extends out of the mounting frame 6. When the first grinder 7 moves to disengage from the guide groove of the guide plate 10, at this time, the first grinder 7 is completely retracted into the mounting frame 6 to the left, and the second grinder 8 is completely extended out of the mounting frame 6 and contacts the edge lines on the upper and lower sides of the glass. The mounting frame 6 drives the second grinder 8 to circle clockwise for one circle and then returns to the initial position, so that the second grinder 8 completes the circular grinding around the edge lines on the upper and lower sides of the glass, thereby realizing a multi-directional chamfering operation on the glass.

Similarly, when the first grinding tool 7 slides to the left along the mounting frame 6 to reset, the slider 701 will also limit the first grinding tool 7 to prevent the first grinding tool 7 from sliding to the right at will during chamfering, causing the second grinding tool 8 to slide at will;

When the above operations are completed, the mounting frame 6 and other components return to the initial position, and the motor 5 is turned off. In summary, the present invention utilizes the motor 5 to drive the first grinder 7 and the second grinder 8 to perform multi-directional fine grinding on the glass, and can automatically switch to the chamfering operation after the edging operation is completed, and the operation is simple and convenient.

In conjunction with Figures 7 to 9, it also includes a fixed paddle plate 11, which is fixedly connected to the lower front side of the mounting frame 6. The left front part of the grinding frame 1 is slidably connected with a slide 12 in the front and rear directions, and the rear part of the slide 12 is slidably connected with a movable paddle frame 13 in the up and down directions. The fixed paddle plate 11 moves backward to contact the movable paddle frame 13. The distance of movement and contact between the fixed paddle plate 11 and the movable paddle frame 13 is equal to the width of the guide plate 10, and after the contact, the fixed paddle plate 11 and the movable paddle frame 13 are squeezed and matched. A first spring 14 is fixedly connected between the slide 12 and the movable paddle frame 13. A guide groove 15 is opened on one side of the grinding frame 1 close to the movable paddle frame 13. The guide groove 15 is composed of two front and rear straight sections and a curved section connecting the two straight sections. The length of each straight section of the guide groove 15 is equal to the width of the guide plate 10. The movable paddle frame 13 is slidably connected to the guide groove 15, and a connecting frame 16 is fixedly connected between the guide plate 10 and the slide 12.

During the above-mentioned edge grinding and chamfering operation, since the first grinder 7 switches between the first grinder 7 and the second grinder 8 when passing through the guide plate 10, there is a local blank area of the glass opposite to the guide plate 10 that cannot be edged and chamfered. In order to avoid this phenomenon, it is necessary to drive the guide plate 10 to move backward at the same time when the switching is completed and the edge grinding begins, and make the moving distance the same as the width of the guide plate 10, to ensure that the guide plate 10 and its initial position no longer overlap, and then when the switching is completed and the chamfering begins, drive the guide plate 10 to continue to move backward at the same time, and make the continued moving distance still the same as the width of the guide plate 10, to ensure that the guide plate 10 and its second position no longer overlap, so that the glass can be completely edged and chamfered, avoiding the existence of a local blank area that cannot be ground, and the specific implementation of the movement operation of the guide plate 10 is as follows:

When the mounting frame 6 moves backward, it drives the fixed paddle plate 11 to move backward synchronously. When the first mold 7 passes the guide plate 10 completely backward, the fixed paddle plate 11 just contacts the movable paddle frame 13. Then the mounting frame 6 drives the fixed paddle plate 11 to continue to move backward. Under the action of the fixed paddle plate 11, the movable paddle frame 13 drives the first spring 14 to move backward synchronously along the straight part of the front section of the guide groove 15. The movable paddle frame 13 drives the connecting frame 16 to move backward through the slide 12, thereby driving the guide plate 10 to move backward. When the movable paddle frame 13 moves backward to the straight part of the front section of the guide groove 15, the movable paddle frame 13 moves backward to the straight part of the front section of the guide groove 15. After reaching the end of the guide groove 15, the fixed plate 11 drives the movable frame 13 to continue to move backward. Under the guidance of the curved portion of the middle section of the guide groove 15, the movable frame 13 will slide downward, thereby gradually breaking away from the fixed plate 11, so that the fixed plate 11 moves backward over the movable frame 13. At this time, the first spring 14 is reset to drive the movable frame 13 to slide upward and enter the straight portion of the rear section of the guide groove 15, so that the guide plate 10 moves backward a distance the same as the width of the guide plate 10, so that the first grinding tool 7 can completely grind the glass before being switched;

Similarly, after the edge grinding is completed, when the first grinding tool 7 completely passes the moved guide plate 10 backward, the fixed plate 11 just contacts the movable frame 13, and then the mounting frame 6 continues to push the movable frame 13 backward through the fixed plate 11, so that the movable frame 13 drives the first spring 14 to continue to move backward along the straight part of the front section of the guide groove 15, and the movable frame 13 drives the connecting frame 16 to continue to move backward through the slide 12, thereby driving the guide plate 10 to continue to move backward. When it moves to the end of the straight section of the rear section of the guide groove 15 and disengages, the fixed paddle plate 11 will squeeze the movable paddle frame 13 to slide downward, thereby crossing the movable paddle frame 13 again, so that the guide plate 10 continues to move backward for a distance the same width as the guide plate 10, so that the second grinder 8 can completely chamfer the glass. After turning off the motor 5, the slide 12 is manually pulled forward, so that the guide plate 10, the movable paddle frame 13, the first spring 14 and the connecting frame 16 move forward and return to the initial position.

Embodiment 2: On the basis of Embodiment 1, in combination with FIG10, it also includes a baffle 17 symmetrically distributed along the guide plate 10, the baffle 17 prevents the guide plate 10 from incorrectly guiding the first mold 7, the baffle 17 is slidably connected to the guide plate 10, the first mold 7 is frictionally engaged with the baffle 17, and a second spring 18 is fixed between the baffle 17 and the guide plate 10.

When the first mold 7 moves backward, it will move straight and obliquely along a path of the X-shaped guide groove of the guide plate 10, and will come into friction contact with the baffle 17 on the path, and then simultaneously drive the baffle 17 to slide on the guide plate 10, so that the baffle 17 blocks the channel on another intersecting path, preventing the first mold 7 from turning to another path when passing the intersection, thereby ensuring to a certain extent that the guide plate 10 correctly guides the first mold 7.

In conjunction with Figure 11, it also includes a third spring 19, which is fixed between the grinding frame 1 and the placement cylinder 2. An L-shaped frame 20 is fixed to the left front side of the placement cylinder 2. A protruding bevel is provided on the side of the first grinding tool 7 close to the L-shaped frame 20. The L-shaped frame 20 moves upward to squeeze the bevel on the first grinding tool 7, so that the first grinding tool 7 moves slightly to the right. The activity space of the X-shaped guide groove of the guide plate 10 can ensure that the first grinding tool 7 will not deviate from the X-shaped guide groove of the guide plate 10 to the right.

After the polished glass on the placement tube 2 is removed, the third spring 19 in the compressed state is reset due to the absence of the weight of the glass, thereby driving the placement tube 2 to slide upward, and then driving the L-shaped frame 20 to move upward. The L-shaped frame 20 squeezes the bevel on the first mold 7, causing the first mold 7 to move slightly to the right, and finally causing the second mold 8 to retract slightly along the mounting frame 6, so that when the glass is pushed from front to back onto the placement tube 2, the left side of the glass will not collide with the second mold 8 first, thereby avoiding the glass from colliding with the second mold 8 and breaking under the action of strong thrust when pushing the glass. After the glass is placed on the placement tube 2, the placement tube 2 slides downward under the action of the gravity of the glass, the third spring 19 is compressed, and the placement tube 2 drives the L-shaped frame 20 to move downward and reset.

In conjunction with Figure 12, it also includes two positioning plates 21 for positioning the glass. The two positioning plates 21 are slidably connected to the right side of the grinding frame 1 and the rear side of the grinding frame 1 respectively. A magnetic block 22 is fixedly connected to the top of the positioning plate 21, and an electromagnet 23 is fixedly connected to the side of the grinding frame 1 close to the magnetic block 22. The switch of the motor 5 is electrically connected to the electromagnet 23 through the control module. When the electromagnet 23 is energized, the magnetic block 22 and the electromagnet 23 are magnetically attracted to cooperate. When the magnetic block 22 and the electromagnet 23 are adsorbed, the position of the positioning plate 21 will not block the circular path of the mounting frame 6, the first mold 7 and the second mold 8.

When the conveying equipment pushes the glass from front to back onto the placement cylinder 2, the positioning plate 21 on the right and the positioning plate 21 on the rear jointly position the glass to prevent inaccurate positioning when placing the glass and to avoid affecting the fine grinding effect of the glass. When the switch of the motor 5 is turned on to start grinding, the switch of the motor 5 controls the electromagnet 23 to be energized. Under the action of magnetic attraction, the magnetic block 22 drives the positioning plate 21 to slide upward to avoid affecting the subsequent edge grinding and chamfering operations on the glass. When the switch of the motor 5 is turned off, the switch of the motor 5 controls the electromagnet 23 to be de-energized. Under the action of gravity, the magnetic block 22 and the positioning plate 21 slide downward.

The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
