Description

Technical Field

[0001] This utility model relates to the field of filter bag production technology, and more specifically, it relates to an edge-grinding mechanism for welding the side edges of filter bag fabric in a filter bag production line. Background Technology

[0002] As a core component of industrial dust removal and liquid filtration, filter bags require a sealing connection on their sides through a fusion process. The edge grinding process before fusion is a key step to ensure the bonding strength. The core function of the edge grinding mechanism is to grind the sides of the filter bag cloth flat and remove burrs, so that the fusion surface fits tightly and avoids dust and water leakage due to uneven contact surfaces.

[0003] In existing technologies, filter bag cloth thicknesses vary, and fixed spacing of the clamping structure can easily lead to displacement of thin cloth and damage to thick cloth, affecting the edge grinding accuracy. Grinding wheels are prone to wear after long-term use, and traditional bolt fixing methods require tools and are time-consuming to replace, affecting production line efficiency.

The rod 8 is provided with a connecting groove 14, the movable frame 2 is provided with a movable motor 15, the motor shaft of the movable motor 15 is provided with a movable screw 16, the movable screw 16 is provided with symmetrical and opposite threads, the movable screw 16 is threadedly connected with a movable block 17, the movable frame 2 is fixedly mounted on the movable block 17, the support block 3 is provided with an adjusting plate 18, the clamping rod 4 is slidably connected to the clamping plate 5, the clamping rod 4 is provided with a clamping plate 19, the clamping plate 19 and the adjusting plate 18 are provided with a clamping spring 20, the support block 3 is rotatably provided with an adjusting screw 21, the top of the adjusting screw 21 is provided with an adjusting handle 22, the adjusting screw 21 is threadedly connected to the adjusting plate 18.

[0030] In this embodiment, during use, the filter bag is conveyed through an existing conveying device. The moving motor 15 is started, which drives the moving screw 16 to rotate, thereby causing the moving block 17 and the moving frame 2 to move in opposite directions. The position of the pressing plate 5 is adjusted to accommodate filter cloths of different thicknesses. Then, the side of the filter bag cloth is inserted between the pressing plates 5. Guided by the guide plate 6, the side of the filter bag is smoothly inserted between the pressing plates 5. The adjusting handle 22 is rotated, which drives the adjusting screw 21 to rotate, thereby causing the adjusting plate 18 to move vertically. By moving the position of the adjusting plate 18, the distance between the pressing plate 19 and the adjusting plate 18 is adjusted, and the deformation of the pressing spring 20 is adjusted. This adjusts the elastic force that the pressing spring 20 provides to the pressing plate 19, the pressing rod 4, and the pressing plate 5. The pressing plate 5 further tightens the filter cloth, improving the edge grinding effect. The rotating motor 7 drives the rotating rod 8 and the grinding wheel 9 to rotate, grinding the side of the filter bag cloth. All other operations use existing technology.

[0031] Please see Figures 4-5 As a further embodiment of the overall equipment: the connecting rod 10 is provided with an insertion rod 23, the connecting groove 14 is provided with an insertion groove 24, the cross-section of the insertion rod 23 and the insertion groove 24 is rectangular, the connecting groove 14 is provided with a reset ring 25, the rotating rod 8 is provided with a moving ring 26, the rotating rod 8 is provided with a moving groove 27, the moving ring 26 and the reset ring 25 are provided with a moving slider 28, the rotating rod 8 is provided with a fixed ring 29, and the fixed ring 29 and the moving ring 26 are provided with a fixed spring 30.

[0032] More specifically, during the connection of the connecting device, the rotating rod 8 is aligned with the connecting rod 10 of the grinding wheel 9, so that the connecting rod 10 extends into the connecting groove 14. When it extends, the rotating rod 8 presses the locking block 13 and the locking spring 12 into the locking groove 11. When the connecting rod 10 is fully extended into the connecting groove 14, the locking block 13 pops out under the elastic force of the locking spring 12, fixing the position of the connecting rod 10. At the same time, the insertion rod 23 extends into the insertion groove 24, which facilitates fixing the relative position of the rotating rod 8 and the grinding wheel 9, thereby completing the connection between the rotating rod 8 and the grinding wheel 9. During disassembly, the position of the moving ring 26 is moved towards the fixed ring 29. The moving ring 26 compresses the fixed spring 30. The moving ring 26 drives the reset ring 25 to move through the moving slider 28. The reset ring 25 presses the locking block 13, so that the locking block 13 extends into the locking groove 11, which facilitates the removal of the rotating rod 8 and improves the convenience of installing and disassembling the grinding wheel 9.

[0033] In summary, the overall equipment operates as follows: During use, the filter bags are conveyed via the existing conveying device. The moving motor 15 is started, which drives the moving screw 16 to rotate, thereby causing the moving block 17 and the moving frame 2 to move in opposite directions. The position of the pressing plate 5 is adjusted to accommodate filter cloths of different thicknesses. Then, the side of the filter bag cloth is inserted between the pressing plates 5. Guided by the guide plate 6, the side of the filter bag is smoothly inserted between the pressing plates 5. The adjusting handle 22 is rotated, which drives the adjusting screw 21 to rotate, thereby causing the adjusting plate 18 to move vertically. By moving the position of the adjusting plate 18, the distance between the pressing plate 19 and the adjusting plate 18 is adjusted, and the deformation of the pressing spring 20 is adjusted. This adjusts the elastic force that the pressing spring 20 provides to the pressing plate 19, the pressing rod 4, and the pressing plate 5. The pressing plate 5 further tightens the filter cloth, improving the edge grinding effect. The motor 7 is rotated, which drives the rotating rod 8 and the grinding wheel 9 to grind the side of the filter bag cloth. All other operations use existing technology.

[0034] When connecting the device, align the rotating rod 8 with the connecting rod 10 of the grinding wheel 9, so that the connecting rod 10 extends into the connecting groove 14. When extending, the rotating rod 8 presses the locking block 13 and the locking spring 12 into the locking groove 11. When the connecting rod 10 is fully extended into the connecting groove 14, the locking block 13 pops out under the elastic force of the locking spring 12, fixing the position of the connecting rod 10. At the same time, the insertion rod 23 extends into the insertion groove 24, which facilitates fixing the relative position of the rotating rod 8 and the grinding wheel 9, thereby completing the connection between the rotating rod 8 and the grinding wheel 9. When disassembling, move the position of the moving ring 26 to the side of the fixing ring 29. The moving ring 26 compresses the fixing spring 30. The moving ring 26 drives the reset ring 25 to move through the moving slider 28. The reset ring 25 presses the locking block 13, so that the locking block 13 extends into the locking groove 11, which facilitates the removal of the rotating rod 8 and improves the convenience of installing and disassembling the grinding wheel 9.
