Waterproof edge-grinding structure and glass sheet edge-grinding device thereof. Technical Field

[0001] This utility model relates to the field of glass processing and production technology, and in particular to a waterproof edge-grinding structure and a glass sheet edge-grinding device having the same. Background Technology

[0002] Sheet materials, such as glass, typically require edge grinding. During the grinding process, water is continuously supplied for lubrication and cooling of the grinding wheels, generating a large amount of dirty water containing glass powder.

[0004] According to a first aspect of the present invention, a waterproof edge-grinding structure includes: a conveyor line on which a sheet material can move forward; an edge-grinding device for grinding the edge of the sheet material, the edge-grinding device being located on the left and / or right side of the conveyor line, and a cooling water device being provided on the edge-grinding device; and an edge-pressing device located between the conveyor line and the edge-grinding device, the edge-pressing device including a plurality of edge-pressing blocks, the edge-pressing blocks being able to press down on the left and / or right side of the upper side of the sheet material, each edge-pressing block being arranged along the front-back direction, the rear side of the edge-pressing block being provided with a rear protrusion, the front side of the edge-pressing block being provided with a front concave portion, the rear protrusion extending into the front concave portion, and a water-sealing gap being formed between adjacent rear protrusions and front concave portions.

[0005] According to some embodiments of the present invention, the pressing device further includes an upper conveyor belt, and a pressing block groove is provided on the lower side of the pressing block. The pressing block groove can lock the left and right sides of the upper conveyor belt, and the lower side of the pressing block can press the upper conveyor belt.

[0006] According to some embodiments of the present invention, the pressing device includes a fixing block, and a pressure spring plate is connected between the lower side of the fixing block and the upper side of the pressing block, the pressure spring plate being elastic.

[0007] According to some embodiments of the present invention, the pressing device includes a detection plate, and a sensor is provided on the pressure spring plate, the sensor being able to monitor the positional change between the sensor and the detection plate.

[0008] According to some embodiments of this utility model, vertical plates are provided on the left and right sides of the upper side of the pressing block, and the lower end of the pressure spring plate is connected to the vertical plate through the pressing block pivot. The pressing block pivot extends in the left and right direction, and the pressing block can rotate up and down around the pressing block pivot.

[0009] According to some embodiments of the present invention, the rear convex portion has rear end faces on both the left and right sides, the front concave portion has front end faces on both the left and right sides, and the gap between the adjacent rear end faces and the front end faces also forms the water-sealing gap.

[0010] The edge-grinding waterproof structure according to the embodiment of this utility model has at least the following technical effects:

[0011] 1. The rear protrusion of the pressing block of the pressing device extends into the front concave part of the adjacent pressing block to form a water-sealing gap. Even if the cooling water seeps into the water-sealing gap, it forms a water film to prevent the cooling water from leaking out of the pressing device. This ensures that each pressing block can fully press the plate, while also ensuring that the cooling water can be blocked by the pressing device and will not flow to the middle of the plate, keeping the plate clean and avoiding affecting the subsequent processing of the plate.

[0012] 2. The pressing groove of the pressing block can lock the left and right sides of the upper conveyor belt, which plays a role in guiding the upper conveyor belt and preventing the upper conveyor belt from shifting or loosening during the operation;

[0013] 3. The sensor and the detection plate work together to detect the deformation of the pressure spring plate, which can automatically determine whether the plate is pressed by the edge pressing block or whether the plate has entered the pressure position range of the edge pressing device, ensuring that the edge grinding work is carried out normally.

[0014] The glass plate edging device according to the second aspect of the present invention includes the edging waterproof structure according to the first aspect of the present invention.

[0015] According to some embodiments of the present invention, a lower support device is provided on the lower side of the pressing device. The lower support device includes a lower conveyor belt and a lower driving device. The lower conveyor belt can press against the left and / or right sides of the lower side of the plate, and the lower driving device can drive the lower conveyor belt to move.

[0016] According to some embodiments of the present invention, the edge grinding device includes a plurality of grinding mechanisms, each of which is arranged along the front-back direction. Each grinding mechanism includes a grinding wheel and a grinding wheel motor, and the grinding wheel motor can drive the grinding wheel to rotate.

[0017] According to some embodiments of the present invention, the cooling water device is connected to an external cooling water source, and the cooling water device includes a plurality of nozzles, which are capable of spraying cooling water onto the corresponding grinding wheel.

[0018] The glass plate edge grinding device according to the embodiment of this utility model has at least the following beneficial effects:

[0019] 1. The rear protrusion of the pressing block of the pressing device extends into the front concave part of the adjacent pressing block to form a water-sealing gap. Even if the cooling water seeps into the water-sealing gap, it forms a water film, which prevents the cooling water from leaking out of the pressing device. This ensures that each pressing block can fully press the plate, while also ensuring that the cooling water can be blocked by the pressing device and will not flow to the middle of the plate, keeping the glass plate clean and avoiding affecting the subsequent processing of the glass plate.

[0020] 2. The edge grinding device includes several grinding mechanisms, each of which has a grinding wheel that independently grinds the edge of the sheet metal, thus achieving precise and flexible edge grinding.

[0036] The edge-grinding waterproof structure according to an embodiment of the present invention is described below with reference to Figures 1 and 2.

[0037] As shown in Figures 1 and 2, the edge-grinding waterproof structure according to an embodiment of the present invention includes a conveyor line 100, an edge-grinding device 200, and an edge-pressing device 400.

[0038] Conveyor line 100, on which the sheet 101 can move forward; edge grinding device 200 is used to grind the edge of the sheet 101, the edge grinding device 200 is located on the left and / or right side of the conveyor line 100, and a cooling water device 300 is provided on the edge grinding device 200; Referring to Figure 3, edge pressing device 400 is located between the conveyor line 100 and the edge grinding device 200, the edge pressing device 400 includes a plurality of edge pressing blocks 410, referring to Figures 4 and 5, the edge pressing blocks 410 can press the left and / or right side of the upper side of the sheet 101, each edge pressing block 410 is arranged in the front-back direction, the rear side of the edge pressing block 410 is provided with a rear protrusion 411, the front side of the edge pressing block 410 is provided with a front concave part 413, the rear protrusion 411 extends into the front concave part 413, and a water-sealing gap 420 is formed between adjacent rear protrusions 411 and front concave parts 413.

[0039] For example, as shown in Figures 1 and 2, the conveyor line 100 remains relatively stationary during operation, while the sheet material 101 can move forward on the conveyor line 100. The edge-grinding device 200 is used to grind the edges of the sheet material 101. Located on the left and / or right side of the conveyor line 100, the edge-grinding device 200 can perform edge-grinding operations on the left and / or right edges of the sheet material 101. A cooling water device 300 is provided on the edge-grinding device 200 to output cooling water for cooling during edge-grinding operations. Referring to Figure 3, the edge-pressing device 400 is located between the conveyor line 100 and the edge-grinding device 200. The edge-pressing device 400 includes several edge-pressing blocks 410, which can press down on the upper left and / or right sides of the sheet material 101. The edge-pressing blocks 410 are arranged along the front-to-back direction to meet the edge-grinding requirements of the edge-grinding device 200. Referring to Figures 4 and 5, a rear protrusion 411 is provided on the rear side of the pressing block 410, and a front concave portion 413 is provided on the front side of the pressing block 410. The rear protrusion 411 extends into the front concave portion 413, and a water-sealing gap 420 is formed between adjacent rear protrusions 411 and front concave portions 413, so that cooling water will not directly pass through the pressing device 400 and splash or leak onto the plate 101.

[0040] In actual operation, referring to Figure 1, taking the pressing device 400 located on the right side of the conveyor line 100 as an example, the rear side of the conveyor line 100 serves as the input side, and the front side of the conveyor line 100 serves as the output side. The sheet material 101 moves forward on the conveyor line 100. When the sheet material 101 reaches the predetermined position on the conveyor line 100, the pressing block 410 of the pressing device 400 presses down on the right side of the sheet material 101. As the sheet material 101 continues to move forward, more and more pressing blocks 410 press down on the right side of the sheet material 101 in sequence. This is equivalent to each pressing block 410 independently pressing down on the corresponding position of the sheet material 101, ensuring that all positions on the right side of the sheet material 101 are fully pressed down by the pressing blocks 410.

[0041] After the edge-pressing device 400 presses the sheet metal 101, the edge-grinding device 200 can perform edge-grinding on the right edge of the sheet metal 101. The cooling water device 300 on the edge-grinding device 200 is responsible for outputting cooling water to the edge-grinding device 200 during the edge-grinding process to cool the edge of the sheet metal 101. During the cooling process, since the edge-pressing device 400 effectively separates the edge-grinding device 200 from the sheet metal 101, the cooling water at the edge of the sheet metal 101 will not directly pass through the edge-pressing device 400 and splash or leak onto the sheet metal 101.

[0042] The rear protrusion 411 of the pressing block 410 extends into the front concave part 413 of the adjacent pressing block 410 to form a water-sealing gap 420. This allows the cooling water to seep into the water-sealing gap 420 and act as a buffer and barrier. It is equivalent to the cooling water being sealed in the water-sealing gap 420 to form a water film, thereby preventing the cooling water from leaking out of the pressing device 400.

[0043] This design ensures that each pressing block 410 of the pressing device 400 can fully press the plate 101, while ensuring that the cooling water can be blocked by the pressing device 400 and will not flow to the middle of the plate 101, thus keeping the plate 101 clean and avoiding affecting the subsequent processing of the plate 101.

[0044] In some embodiments of this utility model, the edge-pressing device 400 further includes an upper conveyor belt 460, and an edge-pressing block groove 415 is provided on the lower side of the edge-pressing block 410. The edge-pressing block groove 415 can lock the left and right sides of the upper conveyor belt 460, and the lower side of the edge-pressing block 410 can press down on the upper conveyor belt 460. That is, when the edge-pressing block 410 presses down on the upper conveyor belt 460, it also presses down on the plate 101 by pressing down on the upper conveyor belt 460. The upper conveyor belt 460 can move and drive the plate 101. That is, when the edge-pressing block 410 presses down on the plate 101, the upper conveyor belt 460 can still drive the plate 101 to move. The edge-pressing block groove 415 can guide the upper conveyor belt 460 and prevent the upper conveyor belt 460 from shifting or loosening during the movement.

[0045] To ensure that the pressing block 410 can effectively apply pressure to the sheet 101, the pressing device 400 has a pressing block groove 415 specially designed on the lower side of the pressing block 410. The function of this pressing block groove 415 is to ensure that it can hold the left and right sides of the upper conveyor belt 460, thereby ensuring that the pressing block 410 can stably press the upper conveyor belt 460 when pressing down. In this way, when the pressing block 410 applies pressure to the upper conveyor belt 460, it also indirectly applies pressure to the sheet 101. This design allows the sheet 101 to move under the drive of the upper conveyor belt 460, and the sheet 101 can still move smoothly even when the pressing block 410 applies pressure.

[0046] In some embodiments of this utility model, the pressing device 400 further includes an upper conveyor belt guide rail 470, which can hold the upper conveyor belt 460 and guide the upper conveyor belt 460 to move, so as to prevent the upper conveyor belt 460 from shifting or even loosening during the movement.

[0047] In some embodiments of this utility model, the pressing device 400 further includes an upper driving device 462, and the upper conveyor belt 460 is driven to move by the upper driving device 462.

[0048] In some embodiments of this utility model, the pressing device 400 further includes an upper conveyor belt guide wheel 461, through which the upper conveyor belt 460 is guided.

[0049] In some embodiments of this utility model, the upper conveyor belt guide roller 461 includes a first upper conveyor belt guide roller 4611, a second upper conveyor belt guide roller 4612, a third upper conveyor belt guide roller 4613, and a fourth upper conveyor belt guide roller 4614. The first upper conveyor belt guide roller 4611 is located in front of the foremost pressing block 410 on the pressing device 400, the second upper conveyor belt guide roller 4612 is located behind the last pressing block 410 on the pressing device 400, the third upper conveyor belt guide roller 4613 is located above the first upper conveyor belt guide roller 4611, and the fourth upper conveyor belt guide roller 4614 is located above the second upper conveyor belt guide roller 4612.

[0050] In some embodiments of this utility model, a water guide groove 417 is provided on the pressing block groove 415. The water guide groove 417 can serve as a space for temporarily storing cooling water on the pressing block groove 415, so as to prevent the cooling water between the pressing block 410 and the upper conveyor belt 460 from splashing out directly under pressure when the pressing block 410 presses against the upper conveyor belt 460.

[0051] The function of the pressing block groove 415 is to provide a temporary storage space for cooling water. Specifically, it is to prevent the cooling water that is originally between the pressing block 410 and the conveyor belt 460 from being squeezed out and splashed due to pressure during the process of the pressing block 410 tightly pressing the conveyor belt 460. In this way, the water guide groove 417 at the pressing block effectively reduces the possibility of cooling water flowing onto the board.

[0052] In some embodiments of this utility model, the pressing device 400 includes a fixing block 430, and a pressure spring plate 440 is connected between the lower side of the fixing block 430 and the upper side of the pressing block 410. The pressure spring plate 440 is elastic. The fixing block 430 serves as a fixing structure for the pressing block 410. The pressure spring plate 440 uses its elasticity to provide downward pressure to the pressing block 410 when pressing the plate 101. This is equivalent to using the elasticity of the pressure spring plate 440 to press the pressing device 400 tightly against the upper surface of the plate 101.

[0053] In some embodiments of this invention, the pressure spring plate 440 is an inclined plate. This allows for the application of more sufficient pressure to the pressure block 410.

[0054] In some embodiments of this utility model, the pressing device 400 includes a detection plate 450 and a sensor 441 is provided on the pressure spring plate 440. The sensor 441 can monitor the positional change between the sensor 441 and the detection plate 450. The detection plate 450 is relatively fixed on the pressing device 400, while the sensor 441 can move with the deformation of the pressure spring plate 440. This is equivalent to the sensor 441 and the detection plate 450 working together to detect the deformation of the pressure spring plate 440, so as to determine whether the plate 101 is pressed by the pressing block 410 or whether the plate 101 has entered the pressure position range of the pressing device 400.

[0055] When the sheet material 101 reaches the position of the pressing device 400, the upper side of the sheet material 101 will push the upper conveyor belt 460 upward, thereby applying an upward force to the pressing block 410, and the pressing block 410 will also move upward. The pressing block 410 will inevitably cause the pressure spring plate 440 to undergo elastic deformation, thereby causing the sensor 441 on the pressure spring plate 440 to follow the position. The displacement direction of the sensor 441 is related to the shape of the pressure spring plate 440.

[0056] Since the detection plate 450 is relatively fixed on the pressing device 400, and the sensor 441 corresponds to the detection plate 450, the displacement of the sensor 441 can be monitored in real time to detect the displacement change and generate a signal to determine whether the pressing block 410 presses down on the pressing plate 101.

[0057] If the edge-pressing block 410 or the upper conveyor belt 460 wears excessively, the edge-pressing block 410 will no longer press the plate 101 firmly. The plate 101 will then be unable to push the edge-pressing block 410 a sufficient distance, and the signal detected by the sensor 441 after displacement will inevitably not meet the preset parameter requirements. This indicates that the plate 101 is not being pressed firmly. Then, the upper conveyor belt 460, edge-pressing block 410, pressure spring plate 440, or other relevant components can be repaired or replaced according to the actual situation.

[0058] In some embodiments of this utility model, since the pressing of the first pressing block 410 of the pressing device 400 is in a transitional state, it cannot fully reflect whether the actual pressing has been achieved. However, by placing the sensor 441 between the first pressing block 410 and the second pressing block 410, it is possible to quickly detect whether the plate 101 is pressed, that is, whether the thickness of the plate 101 matches the reserved gap between the current pressing device 400 and the lower support device 500, thereby enabling timely detection of problems and reducing losses caused by failures.

[0059] In some embodiments of this utility model, the sensor 441 may be a contact or non-contact position sensor.

[0060] In some embodiments of this utility model, the sensor 441 can be a proximity switch. After the plate 101 lifts the upper conveyor belt 460 and then the pressing block 410, the pressure spring plate 440 also undergoes elastic deformation, thereby causing the sensor 441 to move upward. If the proximity switch, acting as the sensor 441, can press against the detection plate 450, it indicates that the pressing block 410 has sufficiently pressed against the plate 101. Conversely, if the sensor 441 still cannot press against the detection plate 450 after the plate 101 has moved to the pressing device 400 position, it indicates that the upper conveyor belt 460, the pressing block 410, the pressure spring plate 440, or other related components of the pressing device 400 are malfunctioning and need to be replaced. Proximity switches have lower cost, require less installation space, have strong waterproof performance, and provide stable signals.

[0061] In some embodiments of this utility model, a detection plate through hole 451 is provided on the detection plate 450, and the sensor 441 passes through the detection plate through hole 451, which can improve the detection accuracy of the sensor 441.

[0062] In some embodiments of this utility model, vertical plates 416 are provided on the left and right sides of the upper side of the pressing block 410. The lower end of the pressure spring plate 440 is connected to the vertical plates 416 through a pressing block pivot 442. The pressing block pivot 442 extends in the left and right direction, and the pressing block 410 can rotate up and down around the pressing block pivot 442. In this way, the pressing block 410 can adjust its angle to cooperate with the work of pressing the plate 101.

[0063] In some embodiments of this utility model, the rear convex portion 411 has a rear end face 412 on the left and right sides, and the front concave portion 413 has a front end face 414 on the left and right sides. The gap between the adjacent rear end face 412 and the front end face 414 also forms a water-sealing gap 420, which can better ensure the water-sealing effect of the water-sealing gap 420.

[0064] In some embodiments of this utility model, a front inclined surface 418 is provided at the front end of the pressing block groove 415, and a rear inclined surface 419 is provided at the rear end of the pressing block groove 415 and at the lower side of the rear end of the rear protrusion 411. The design of the front inclined surface 418 and the rear inclined surface 419 can reduce the wear of the pressing block 410 on the upper conveyor belt 460.

[0065] In some embodiments of this utility model, a pre-pressing device 480 is provided at the rear of the pressing device 400. The pre-pressing device 480 includes a pre-pressing roller 481, a pre-pressing cylinder 482, and a pre-pressing monitoring probe 483. When the pre-pressing monitoring probe 483 detects that the sheet material 101 has reached its designated position, the pre-pressing cylinder 482 controls the pre-pressing roller 481 to descend and press down on the sheet material 101. This ensures that when the sheet material 101 enters the pressing position range of the pressing device 400, the pressing block 410 can effectively press the sheet material 101 firmly.

[0066] The glass sheet edging device according to a second aspect embodiment of the present invention includes the edging waterproof structure according to the first aspect embodiment of the present invention. Referring to Figures 1 and 2, the edging waterproof structure of the present invention is applicable to glass sheet processing. The rear protrusion 411 of the pressing block 410 extends into the front concave portion 413 of the adjacent pressing block 410 to form a water-sealing gap 420. This allows cooling water to seep into the water-sealing gap 420, acting as a buffer and barrier, equivalent to the cooling water being sealed in the water-sealing gap 420 to form a water film, thereby preventing cooling water from leaking out of the pressing device 400. This design ensures that each pressing block 410 of the pressing device 400 can fully press the sheet 101, while ensuring that cooling water can be blocked by the pressing device 400 and will not flow to the middle of the sheet 101, keeping the sheet 101 clean and avoiding affecting subsequent processing of the sheet 101.

[0067] According to the glass plate edging device of the present invention, by adopting the above-mentioned waterproof edging structure, the number of waterproof components required is reduced, which facilitates the simplified design of the waterproof structure of the glass plate edging device, and can also improve the limiting requirements of the glass plate edging device and enhance the application effect of the new structure.

[0068] In some embodiments of this utility model, a conveyor support frame 110 is provided on the conveyor line 100, and support frame rollers 111 are distributed on the conveyor support frame 110. That is, the conveyor line 100 supports the lower side of the plate 101 through the support frame rollers 111, ensuring that the plate 101 can move smoothly on the conveyor line 100.

[0069] In some embodiments of this utility model, referring to FIG6, a lower support device 500 is provided on the lower side of the pressing device 400. The lower support device 500 includes a lower conveyor belt 510 and a lower drive device 520. The lower conveyor belt 510 can press against the left and / or right sides of the lower side of the plate 101, and the lower drive device 520 can drive the lower conveyor belt 510 to move.
