Description

Technical Field

[0001] This invention relates to the field of material grinding equipment technology, and in particular to a fully automatic intelligent grinding production line. Background Technology

[0002] After being pressed and fired, the edges of the shaped brick blanks of building decorative panels such as ceramic tiles, glass, stone, and artificial stone are not flat enough. In order to obtain building decorative panels that are nearly standard rectangular, several diamond grinding wheels are usually used to grind the original edges of the panels. For example, a blank panel with a rough size of 820×820mm is ground into a panel with a standard size of 800×800mm.

[0003] To improve edge grinding efficiency, existing technologies typically employ edge grinding machines to finely process the perimeter of the formed brick blanks, resulting in uniform perimeter dimensions and a smooth, flat surface for the formed standard slabs. Traditional continuous edge grinding machines usually consist of one or more pairs of grinding wheels and corresponding power heads. The grinding wheels are typically arranged in pairs, such as A1 and B1, A2 and B2, and so on, up to A20 and B20, or even more pairs. As the working layer of the grinding wheels is continuously worn down, the depth of cut of each grinding wheel needs to be adjusted periodically. Traditional edge grinding machines involve manual, independent feeding of the grinding wheels, resulting in a non-constant feed rate for each wheel, which presents the following drawbacks: 1. The workload is enormous and the labor intensity is extremely high, requiring operators to have strong observation skills and work experience; 2. Uneven depth of cut leads to unstable lifespan of each grinding wheel; 3. Each time a grinding wheel is replaced, the grinding amount of that grinding wheel is taken over by other grinding wheels, which also increases the unevenness of the feed. When the grinding amount that one grinding wheel has to bear is too large, it is easy to cause chipping and corner breakage of the board, thereby increasing the defect rate and the dimensional error of the standard board. Summary of the Invention

[0004] To address the above problems, this invention proposes a fully automated intelligent edge grinding production line.

[0005] The technical solution adopted in this invention is: a fully automatic intelligent edge grinding production line for processing raw plates into standard plates. The production line includes a frame, on which a conveying mechanism is installed. The conveying mechanism is provided with a conveyor belt for continuously conveying the raw plates in the left-right direction. It also includes: There are two translation drive mechanisms, which are respectively installed on the front and rear sides of the frame; The frame base plate is linked to the translation drive mechanism, which is used to drive the frame base plate to translate back and forth. A central control unit, mounted on the frame, is used to control the operation of the translation drive mechanism; At least one edge grinding station is arranged at intervals along the extension direction of the conveyor belt. The edge grinding station includes two edge grinding machines arranged in front of and behind each other. The edge grinding machines are mounted on the frame base plate and the edge grinding machines are provided with edge grinding wheels on the side of the edge grinding machine closest to the conveyor belt. Along the conveying direction of the blank plate, the distance between the two grinding wheels and the center line at each grinding station decreases in a stepped manner. The distance between the two grinding wheels at the grinding station at the end of the conveying process is the standard set width of the specification plate.

[0006] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0007] Preferably, the conveyor belt or the frame seat is provided with at least one sensor, which is used to detect whether the width of the plate after the last edge grinding station is consistent with the standard set width of the specification plate, and to feed back the detection result to the central processing mechanism.

[0008] Preferably, the positions of the two grinding wheels located at the same grinding station are symmetrical, and the grinding amount of each side of the plate is equal to 1 / 2 of the difference between the width of the blank plate and the width of the standard plate.

[0009] Preferably, the central processing mechanism is used to control the two frame base plates to move synchronously towards each other, and to drive the cutting depth of all grinding wheels to be adjusted synchronously at the same time.

[0010] Preferably, the grinding machine is equipped with an adjustment structure for adjusting the front and rear positions of the grinding wheels. The processing production line has a debugging stage and a formal working stage. In the debugging stage, based on the size of the blank plate, the number of grinding stations, the total grinding amount, and the grit size and performance of the grinding wheels, the adjustment structure adjusts each grinding wheel to a suitable position. In the formal working stage, the adjustment structure is locked, the grinding wheels and the frame base plate remain relatively stationary, and the translation drive mechanism adjusts the front and rear positions of the frame base plate based on the instructions of the central control mechanism.

[0011] Preferably, the edge grinding machine includes a seat plate, and a drive motor and a power head mounted on the seat plate. The drive motor is used to drive the power head to rotate. A flange is mounted on the power head, and the edge grinding wheel is mounted on the flange. The adjustment structure is disposed between the drive motor and the seat plate.

[0012] Preferably, the grinding wheel is installed on the edge of the flange and is placed at an angle, and the contact position between the grinding wheel and the edge of the blank plate is located upstream of the flange.

[0013] Preferably, the grinding wheel is mounted on the normal surface of the flange.

[0014] Preferably, along the conveying direction of the blank plate, the distance between the two grinding wheels at each grinding station decreases in an arithmetic sequence.

[0015] More preferably, all grinding wheels located on the same frame base plate are replaced and installed in the same batch at the same time.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Before starting the equipment, the feed amount of the grinding wheel at each grinding station needs to be preset independently according to parameters such as the size of the blank plate, the number of grinding stations, the performance of the grinding wheel, and the total grinding amount. After the setting is completed, the grinding amount of the grinding wheel at each position is constant. This avoids the defect of uneven load on the grinding wheel in the traditional grinding line, which can effectively improve the service life of the grinding wheel and the drive motor and save costs. 2. Since the grinding machines on the same side are all mounted on the same frame plate, when the sensor detects that the width of the plate after grinding at the last grinding station is greater than the standard set width of the specification plate, the sensor transmits the information to the central control mechanism. The central control mechanism controls the two translation drive mechanisms to work and drives the two frame plates to translate towards each other simultaneously, so that the grinding wheels on both sides are fed synchronously. After the feeding is completed, the depth of cut of each grinding wheel remains unchanged, which improves the grinding efficiency and life uniformity of the grinding wheels and reduces the labor intensity of the workers. 3. After the working life of the grinding wheel is reached, the grinding wheel is not replaced individually, but in batches or all edge groups at once, thereby improving work efficiency; 4. When the dimensions of the blank plate change, it is necessary to enter the debugging stage. All edge grinding machines must stop working. At this time, the position of each edge grinding wheel can be adjusted independently through the adjustment structure. After entering the formal working stage, the edge grinding wheel and the power head cannot move relative to the seat plate. They can only move synchronously with the frame plate according to the instructions of the central processing mechanism. The movement of each edge grinding wheel is equal.

[0024] Specific implementation plan: Example 1: See Figures 1-4 This invention is a fully automated intelligent edge grinding production line for processing a rough plate 5 into a standard plate 7. The production line includes a frame, on which a conveying mechanism is mounted. The conveying mechanism is equipped with a conveyor belt 1 for continuously conveying the rough plate 5 in a left-right direction. It also includes: There are two translation drive mechanisms, which are installed on the front and rear sides of the frame respectively; The frame base plate 2 is linked to the translation drive mechanism, which is used to drive the frame base plate 2 to translate back and forth. The central control unit, mounted on the frame, is used to control the operation of the translation drive mechanism; At least one edge grinding station is arranged at intervals along the extension direction of the conveyor belt 1. The edge grinding station includes two edge grinding machines 3 arranged in front and behind each other. The edge grinding machines 3 are mounted on the frame base plate 2. The edge grinding machine 3 is provided with an edge grinding wheel 35 on the side of the edge grinding machine 3 closest to the conveyor belt 1. Along the conveying direction of the blank plate 5, the distance between the two grinding wheels 35 and the center line at each grinding station decreases in a stepped manner. The distance between the two grinding wheels 35 at the grinding station at the end of the conveying process is the standard set width of the specification plate 7.

[0025] Note that in this embodiment, the translation drive mechanism can be implemented using a motor + lead screw and nut structure, with the frame base plate mounted on the nut. This is existing technology and will not be explained in detail here (not shown in the figure).

[0026] As a preferred embodiment of this example, please refer to Figure 1 As can be seen, there are two sensors 4 arranged in opposite directions on the conveyor belt 1 or the frame seat plate 2. The sensors 4 are used to detect whether the width of the plate after the last edge grinding station is consistent with the standard set width of the specification plate 7, and to feed back the detection results to the central processing unit.

[0027] Here, two sensors 4 work together to detect the width of the plate after the last edge-grinding station. When the width of the plate after edge-grinding is equal to the standard set width (theoretically, the working layer of the edge-grinding wheel 35 is always worn, and if the wear level does not reach the threshold, it is still within the error range and can be regarded as equal), all edge-grinding machines 3 can continue to perform edge-grinding operations. When the width of the plate after edge-grinding is greater than the standard set width, it means that the wear of the working layer of the edge-grinding wheel 35 has exceeded the threshold. The central control mechanism receives the detection signal from the sensor 4, controls the two translation drive mechanisms to work, and drives the two frame base plates 2 to translate towards each other simultaneously, so that the edge-grinding wheels 35 on both sides are fed synchronously. After the feeding is completed, the feed amount of each edge-grinding wheel 35 remains unchanged, which improves the grinding efficiency and lifespan uniformity of the edge-grinding wheel 35.

[0028] Then, please continue reading. Figure 1 The two grinding wheels 35 located at the same grinding station are symmetrically positioned front and back. The grinding amount on each side of the board is equal to 1 / 2 of the difference between the width of the blank board 5 and the width of the standard board 7.

[0029] Furthermore, in this embodiment, along the conveying direction of the blank plate 5, the distance between the two grinding wheels 35 at each grinding station decreases in an arithmetic sequence.

[0030] To make it easier to understand, the following example is provided: exist Figure 1 There are 5 edge grinding stations, so there are 5 pairs of edge grinding wheels. Along the conveying direction of the blank plate 5, A1 and B1 are a pair, A2 and B2 are a pair, A3 and B3 are a pair, A4 and B4 are a pair, and A5 and B5 are a pair. The distance between A1 and B1 is set as D1, the distance between A2 and B2 is set as D2, the distance between A3 and B3 is set as D3, the distance between A4 and B4 is set as D4, and the distance between A5 and B5 is set as D5.

[0031] When a blank plate 5 with a width of 610mm needs to be ground into a standard plate 7 with a width of 600mm, D1 can be set to 608mm, D2 to 606mm, D3 to 604mm, D4 to 602mm, and D5 to 600mm. At this time, the distance between the grinding wheels 35 of A1 and B1 and the center line is 304mm, the distance between the grinding wheels 35 of A2 and B2 and the center line is 303mm, the distance between the grinding wheels 35 of A3 and B3 and the center line is 302mm, the distance between the grinding wheels 35 of A4 and B4 and the center line is 301mm, and the distance between the grinding wheels 35 of A5 and B5 and the center line is 300mm.

[0032] In the above text, the minimum spacing between the last pair of grinding wheels 35 (A5, B5) is the final size of the finished workpiece. In this embodiment, the workpiece mainly refers to ceramic tiles, flat glass, artificial stone or stone slabs.

[0033] Next, in this embodiment, the grinding machine is equipped with an adjustment structure for adjusting the front and rear positions of the grinding wheels. The processing production line has a debugging stage and a formal working stage. In the debugging stage, based on the size of the blank plate, the number of grinding stations, the total grinding amount, and the grit size and performance of the grinding wheels 35, the adjustment structure adjusts each grinding wheel 35 to a suitable position. In the formal working stage, the adjustment structure is locked, the grinding wheels 35 and the frame base plate 2 remain relatively stationary, and the translation drive mechanism adjusts the front and rear positions of the frame base plate 2 based on the instructions of the central control mechanism.

[0034] It should be noted that when the dimensions of the blank plate 5 change, such as the width of the blank plate 5 becoming 612mm, the debugging stage must be entered. All edge grinding machines 3 must stop working. At this time, the position of each edge grinding wheel 35 can be adjusted independently through the adjustment structure. After entering the formal working stage, neither the edge grinding wheel 35 nor the power head 33 can move relative to the seat plate 31. They can only move synchronously with the frame plate according to the instructions of the central processing mechanism. The amount of movement of each edge grinding wheel 35 is equal.

[0035] Please see Figure 4 When it is necessary to process the blank plate 5 into the standard plate 7, the A and B sides of the blank plate 5 need to be ground flat through the processing production line in this embodiment to form a semi-finished plate 6. Then, the semi-finished plate 6 is rotated 90° by a rotating mechanism and transferred back into the processing production line to grind the C and D sides of the semi-finished plate 6 flat, thus obtaining the standard plate 7. The aforementioned rotating mechanism and the transfer mechanism used to transfer the semi-finished plate 6 are both prior art and will not be described in detail here.

[0036] Then, in this embodiment, the central processing mechanism is used to control the two frame base plates 2 to move synchronously towards each other, and to drive the cutting depth of all the grinding wheels 35 to be adjusted synchronously at the same time.

[0037] As another preferred embodiment of this example, please refer to Figure 2 and Figure 3 As can be seen, the edge grinding machine 3 includes a seat plate 31, a drive motor 32 and a power head 33 mounted on the seat plate 31. The drive motor 32 is used to drive the power head 33 to rotate. A flange 34 is mounted on the power head 33, and the edge grinding wheel 35 is mounted on the flange 34. The adjustment structure is set between the drive motor 32 and the seat plate 31.

[0038] In this embodiment, the adjustment structure includes a slide rail on the seat plate 31 and a slider on one side of the drive motor 32. The slider is slidably mounted on the slide rail. Both the seat plate 31 and the drive motor 32 are provided with a number of positioning holes. After the drive motor 32 is adjusted to a suitable position, a positioning rod is used to pass through the positioning holes to fix the relative position of the drive motor 32 and the seat plate 31 (not shown in the figure).

[0039] Before starting the equipment, the depth of cut of the grinding wheel 35 at each grinding station needs to be preset independently based on parameters such as the size of the blank plate, the number of grinding stations, the performance of the grinding wheel 35, and the total grinding amount. After the setting is completed, the grinding amount of the grinding wheel 35 at each position is constant. This avoids the defect of uneven load on the grinding wheel 35 in traditional grinding lines, effectively improves the service life of the grinding wheel 35 and the drive motor 32, and saves costs.

[0040] Please see Figure 1 As can be seen, in this embodiment, the grinding wheel 35 is installed on the edge of the flange 34 and is placed at an angle. The contact position between the grinding wheel 35 and the edge of the blank plate 5 is located upstream of the flange 34.

[0041] More specifically, all grinding wheels 35 located on the same frame base plate 2 are replaced and installed simultaneously in batches. After the working life cycle of the grinding wheels 35 is reached, the replacement of the grinding wheels 35 is not done individually, but in batches, with each edge group being replaced at once, thereby improving work efficiency.

[0042] Example 2: See Figures 5-7 Unlike Embodiment 1, in this embodiment, the grinding wheel 35 is mounted on the normal surface of the flange 34.

[0043] The above description of a fully automated intelligent edge grinding production line of the present invention is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the inventive concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
