DETAILED DESCRIPTION

[0040] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0041] like Figure 1-9 As shown, a CNC cotton hole opening production line includes a grinding module 1 and a fixing module 2;

[0042] The grinding module 1 includes a grinder 11, a dust collector, a grinding X-direction guide rail 12, a grinding mounting seat 17, and a grinding Y-direction guide rail 13 perpendicular to the grinding X-direction guide rail 12. The grinding mounting seat 17 is slidably disposed on the grinding X-direction guide rail 12 and driven by an X-direction sliding drive mechanism. The grinder 11 is provided with a horizontal outward grinding roller 111. The dust collector includes a dust hood 14. The grinder 11 and the dust hood 14 are both mounted on the grinding mounting seat 17. The dust suction port 141 of the dust hood 14 faces the grinding roller 111 of the grinder 11.

[0043] The grinding X-direction guide rail 12 is slidably disposed on the grinding Y-direction guide rail 13 via a Y-direction sliding drive mechanism;

[0044] The grinding mounting seat 17 is provided with a grinding Z-guide rail, and the grinding Z-guide rail is slidably provided with a mounting support 15, the grinding machine 11 and the dust cover 14 are fixed to the mounting support 15, and the mounting support 15 slides along the grinding Z-guide rail through a Z-direction sliding driving mechanism;

[0045] The fixing module 2 is arranged below the grinding X-guide rail 12 , and a positioning plate 21 is detachably installed on the fixing module 2 . A plurality of semicircular grinding holes 211 opening upward are provided on the upper surface of the positioning plate 21 , and the grinding roller 111 of the grinder 11 is perpendicular to the grinding holes 211 of the positioning plate 21 .

[0046] The CNC cotton hole opening production line controls the grinding path of the grinder 11 by grinding the X-guide rail 12, the Y-guide rail 13, and the Z-guide rail, and grinds and holes the insulation cotton of the glass heating furnace fixed to the fixed module 2, thereby achieving precise hole opening, avoiding the occurrence of broken cotton, and improving the quality of the finished insulation cotton. In addition, the grinding module 1 uses a vacuum cleaner to track dust while the grinding roller 111 of the grinder 11 is grinding, reducing the diffusion of dust generated during grinding and ensuring the health of the staff.

[0047] A positioning plate 21 with a grinding hole 211 of corresponding size is selected according to the size of the opening, and the thermal insulation cotton of the glass heating furnace is fixed to the fixed module 2, and the side wall of the thermal insulation cotton of the glass heating furnace is in close contact with the side wall of the positioning block 21; then the grinding roller 111 of the grinder 11 is driven to accurately grind and open holes on the thermal insulation cotton of the glass heating furnace; when working, the grinding roller 111 of the grinder 11 is driven to rotate by the spindle motor, and the grinding roller 111 of the grinder 11 grinds and opens holes on the thermal insulation cotton of the glass heating furnace fixed on the fixed module 2 along the contour of the grinding hole 211 of the positioning plate 21, and finally a groove of the same size as the grinding hole 211 is formed on the thermal insulation cotton of the glass heating furnace.

[0048] The grinder 11 and the dust hood 14 of the grinding module 1 slide on the grinding X-guide rail 12 through the X-direction sliding drive mechanism; the grinding X-guide rail 12 of the grinding module 1 slides on the grinding Y-guide rail 13 through the Y-direction sliding drive mechanism, thereby driving the grinder 11 and the dust hood 14 of the grinding module 1 to slide on the grinding Y-guide rail 13; the mounting support 15 slides along the grinding Z-guide rail through the Z-direction sliding drive mechanism, thereby driving the grinder 11 and the dust hood 14 to slide up and down relative to the grinding X-guide rail 12; the grinder 11 can move to any position in the three-dimensional space formed by the grinding X-guide rail 12, the grinding Y-guide rail 13 and the grinding Z-guide rail, thereby accurately locating the opening position of the insulation cotton of the glass heating furnace fixed to the fixed module 2, thereby achieving precise opening.

[0049] The debris and dust generated by the grinder 11 during grinding can easily spread to the surrounding area. Since the dust suction port 141 of the grinding module 1 is aimed at the grinder 11, the debris and dust generated by grinding can be immediately absorbed to prevent the debris and dust from further spreading. Since the dust suction hood 14 moves with the grinder 11, the tracking dust suction function can be realized, thereby accurately absorbing the debris and dust generated by the grinding opening of the grinder 11.

[0050] Preferably, the dust hood 14 is further provided with a dust outlet 142, the dust outlet 142 is connected to a discharge pipe, and the discharge pipe is provided with an exhaust fan.

[0051] Through the exhaust effect of the exhaust fan, the debris and dust generated by grinding the insulation cotton of the glass heating furnace enters the dust hood 14, then enters the discharge pipe through the dust outlet 142, and is finally collected in the receiving box.

[0052] Preferably, the length of the dust suction port 141 of the dust suction cover 14 of the grinding module 1 is not less than three times the diameter of the grinding hole 211 of the positioning plate 21 .

[0053] In addition to absorbing the debris and dust generated by the insulation cotton of the glass heating furnace on the grinding hole 211 being ground, the dust suction port 141 of the dust suction hood 14 also absorbs the debris and dust remaining around the insulation cotton of the glass heating furnace on the grinding holes 211 on both sides that have been ground, thereby achieving alternating and repeated dust suction to further reduce the spread of debris and dust.

[0054] Preferably, the fixing module 2 also includes a workbench 22, which is used to fix the insulation cotton of the glass heating furnace. The workbench 22 is provided with positioning plates 21 on both sides parallel to the grinding X-guide rail 12 of the grinding module 1, and the insulation cotton of the glass heating furnace is attached to the positioning plates 21.

[0055] Since the grinding X-guide rail 12 is parallel to the positioning plate 21, after adjusting the grinding X-guide rail 12 of the grinding module 1 to slide on the grinding Y-guide rail 13 of the grinding module 1 so that the grinder 11 is aligned with the positioning plate 21, the sliding path of the grinding machine 11 on the grinding X-guide rail 12 is on the same horizontal line as the positioning plate. During grinding, it is only necessary to control the grinder 11 to slide on the grinding X-guide rail 12 and the grinding Z-guide rail, and it is unnecessary to operate in the direction of the grinding Y-guide rail to locate the position where the hole needs to be opened.

[0056] Preferably, the fixing module 2 further includes a fixing crossbar 23 and a workbench guide rail 24;

[0057] The fixed cross column 23 is slidably connected to the workbench guide rail 24, and protrusions 231 are provided at both ends of the fixed cross column 23. The workbench 22 of the fixed module 2 is placed on the top surface of the fixed cross column 23 and stuck between the two protrusions 231. A lifting drive 25 is provided below the workbench 22.

[0058] The workbench guide rail 24 is fixedly connected to the ground, and the workbench 22 slides quickly on the workbench guide rail 24 through the fixed cross column 23, so as to adjust the position of the heat insulation cotton of the glass heating furnace. The workbench 22 is fixed by the protrusion 231, so as to prevent the workbench 22 from deviating and derailing when sliding on the workbench guide rail 24.

[0059] The lifting driver 25 is fixed to the ground. After the workbench 22 is adjusted to a desired position through the workbench guide rail 24, the lifting driver 25 is operated to raise its output shaft upward, thereby lifting the workbench 22 so that the fixed cross column 23 leaves the workbench guide rail 24 to achieve a fixing effect. The lifting driver 25 can be a lifting motor, a hydraulic cylinder, a jack, etc.

[0060] Preferably, the grinding roller 111 of the grinding machine 11 is a cylindrical structure, and a plurality of grinding blades are provided on the cylindrical surface of the grinding roller 111;

[0061] The surfaces of the grinding X-guide rail 12 and the grinding Y-guide rail 13 of the grinding module 1 are both provided with scales.

[0062] When grinding the hole, the grinding blade on the cylindrical surface of the high-speed rotating grinding roller 111 continuously grinds the insulation cotton of the glass heating furnace; grinding with the cylindrical grinding roller 111 is conducive to forming a smooth curved surface on the insulation cotton of the glass heating furnace.

[0063] When adjusting the position of the grinder 11 of the grinding module 1, the adjustment can be more accurate by comparing the scale and the moving distance.

[0064] Preferably, the grinding module 1 is provided with two grinding Y-direction guide rails 13 , and the grinding X-direction guide rail 12 of the grinding module 1 is movably fixed to the upper surface of the corresponding grinding Y-direction guide rail 13 through a telescopic column 16 .

[0065] The two grinding Y guide rails 13 support and guide the grinding X guide rail 12, so that the grinding X guide rail 12 is balanced and stable. The height of the telescopic column 16 is adjusted to greatly adjust the height of the grinding X guide rail 12 of the grinding module 1, so that there is enough space between the grinding X guide rail 12 of the grinding module 1 and the fixing module 2 to fix the insulation cotton of the glass heating furnace to the fixing module 2.

[0066] Preferably, the CNC cotton hole opening production line further includes a hole opening calibration mold 3, and the hole opening calibration mold 3 includes a mold base plate 32, a positioning portion 33 and a calibration protrusion 31 matched with the grinding hole 211 of the positioning plate 21;

[0067] A plurality of the calibration protrusions 31 are disposed on the bottom surface of the mold substrate 32 and are spaced apart along the length direction of the mold substrate 32;

[0068] One end of the positioning portion 33 is arranged at the end of the mold substrate 32 and connected to the calibration protrusion 31 located at the end of the mold substrate 32. A positioning groove 331 is provided on the top of the other end of the positioning portion 33. When the calibration protrusion 31 of the hole calibration mold 3 is stuck in the grinding hole 211 of the positioning plate 21 of the fixing module 2, the notch of the positioning groove 331 faces directly upward.

[0069] like Figure 8-9 As shown, the left side is the head end of the mold substrate 32, and the right side is the tail end of the mold substrate 32. After the calibration protrusion 31 is clamped on the positioning plate 21 of the fixing module 2, the grinding roller 111 of the grinder 11 is moved into the positioning groove 331 of the positioning portion 33 of the opening calibration mold 3, thereby determining the initial position of the grinding roller 111 of the grinder 11.

[0070] Since there will be slight errors in the size of the ground holes 211 of the positioning plates 21 of each of the fixing modules 2, compared with calibration using a single calibration protrusion 31, multiple calibration protrusions 31 are clamped in the ground holes 211 of the positioning plates 21 of different fixing modules 2, which helps to reduce errors.

[0071] Preferably, the mold base plate 32 of the hole-opening calibration mold 3 is provided with a hanging hole 34;

[0072] The horizontal distance from the center of the positioning groove 331 of the positioning portion 33 of the hole calibration mold 3 to the center of the calibration protrusion 31 located at the tail end of the mold substrate 32 is a fixed value a, the horizontal distance between the centers of two adjacent calibration protrusions 31 is b, the distance between two adjacent sides of two adjacent calibration protrusions 31 is a fixed value c, and the value of the initial position of the grinder 11 of the grinding module 1 is S, S=a-(bc) / 2.

[0073] The hole calibration mold 3 is hung on the wall through the hanging hole 34 for easy storage and use.

[0074] The hole calibration mold 3 with different b values ​​is selected according to the different sizes of the holes for the insulation wool of the glass heating furnace. After the calibration protrusion 31 of the hole calibration mold 3 is clamped in the grinding hole 211 of the positioning plate 21 of the fixing module 2, the value S of the initial position of the grinder 11 of the grinding module 1 is obtained. The grinder 11 of the grinding module 1 is moved into the positioning groove 331 of the positioning part 33 of the hole calibration mold 3, and the value S of the initial position is input into the operation module, and the hole is automatically and accurately ground through the conventional procedure.

[0075] Preferably, the CNC cotton hole opening production line further includes a program control box 41 and a manual direction control button group 42;

[0076] The program control box 41 is electrically connected to the Z-direction sliding drive mechanism of the grinding module 1, the rotation drive mechanism of the grinding machine 11, the X-direction sliding drive mechanism and the Y-direction sliding drive mechanism respectively;

[0077] The manual direction control button group 42 is electrically connected to the program control box 41 .

[0078] The program control box 41 controls the sliding of the grinder 11 and the dust hood 14 on the grinding Z guide rail, the rotation of the grinder 11 of the grinding module 1, the sliding of the grinder 11 and the dust hood 14 on the grinding X guide rail 12, and the sliding of the grinding X guide rail 12 on the grinding Y guide rail 13, thereby realizing automatic and precise grinding and opening.

[0079] The buttons on the manual direction control button group 42 are operated to control the sliding of the grinder 11 and the dust hood 14 on the grinding Z guide rail, the sliding of the grinder 11 and the dust hood 14 on the grinding X guide rail 12, and the sliding of the grinding X guide rail 12 on the grinding Y guide rail 13 through the program control box 41, so as to achieve the purpose of fine-tuning the position of the grinder 11 and the dust hood 14 of the grinding module 1.
