Description

Technical Field

[0001] This application relates to the technical field of auxiliary tools for the production of insulation boards, and in particular to a cutting tool for grooving insulation boards. Background Technology

[0002] When producing composite insulation boards, mortar needs to be applied to the substrate. In order to improve the bonding force between the mortar and the substrate, multiple grooves are usually opened on the substrate. When applying mortar, some of the mortar enters the grooves and solidifies, thereby improving the bonding force between the substrate and the mortar and forming reinforcing ribs in the substrate, thus improving the strength of the composite board.

[0003] Multiple blades are fixed on the drive shaft, which is mounted on the upper side of the conveyor belt. When grooving, the worker places the insulation board on the conveyor belt and passes it under the blades. The motor drives the drive shaft to rotate the blades, thereby grooving the insulation board.

[0004] In related technologies, the blades are fixed on the drive shaft. When the number of slots required on different insulation boards is different, it is difficult to adjust the number of blades on the drive shaft according to the needs of the insulation board, which will have an adverse effect on the applicability. Utility Model Content

[0005] To reduce the adverse effects on applicability, this application provides a cutting tool for grooving insulation boards.

[0006] The present application provides a cutting tool for grooving insulation boards, which adopts the following technical solution:

[0007] A grooving tool for insulation boards includes a drive shaft and a plurality of blades sleeved on the drive shaft. Each adjacent blade is provided with a spacer ring sleeved on the drive shaft. The drive shaft is provided with limiting members corresponding to the blades and the spacer rings. Both ends of the drive shaft are sleeved with fixing rings, and fixing members are provided between the fixing rings and the drive shaft.

[0008] By adopting the above technical solution, both the blade and the spacer ring are sleeved on the drive shaft and installed on the drive shaft by limiting parts, fixing rings and fixing parts. When it is necessary to adjust the number of slots on the insulation board, the number of blades on the drive shaft is adjusted according to the number of slots, and the number of spacer rings between two adjacent blades is increased or decreased, thereby adjusting the spacing between the slots on the insulation board and reducing the adverse effects on applicability.

[0009] Optionally, the limiting member includes a limiting block that corresponds one-to-one with the blade and the spacer ring and is arranged along the length direction of the drive shaft. The limiting blocks are connected end to end in sequence. The inner sidewalls of the blade and the spacer ring are provided with through holes adapted to the limiting blocks. The limiting blocks are inserted into the corresponding through holes.

[0010] By adopting the above technical solution, the blade and the spacer ring are fixed in relative positions on the drive shaft by the limiting block and the through hole, which makes it easy for the drive shaft to drive the blade to rotate through the limiting block, and also makes it easy to adjust the number of blades and spacers on the drive shaft according to the number of slots on the insulation board, thereby reducing the adverse effects on applicability.

[0011] Optionally, the fastener includes a fixing block that is fixedly connected to the side wall of the end of the drive shaft and fixedly connected to the adjacent limiting block. The fixing block is inserted into the corresponding side wall of the fixing ring, and the fixing ring and the fixing shaft are fixedly connected by bolts.

[0012] By adopting the above technical solution, the blade and spacer ring are installed on the drive shaft, and the fixing ring is sleeved on the end of the drive shaft. At this time, the fixing block is inserted into the corresponding fixing ring, and the fixing ring is fixed on the drive shaft by bolts. When it is necessary to adjust the number of slots on the insulation board, the fixing ring is removed and the number of blades and spacer rings on the drive shaft are adjusted to reduce the adverse effects on applicability.

[0013] Optionally, the end of the drive shaft is provided with a mounting plate perpendicular to the drive shaft, the drive shaft is rotatably connected to the mounting plate, one of the mounting plates is provided with a motor that drives the drive shaft to rotate, and the lower end of the mounting plate is provided with a mounting assembly.

[0014] By adopting the above technical solution, the mounting plate is fixed by the mounting components, which facilitates the installation of the drive shaft and the cutting of the blades into the insulation board conveyed on the conveyor belt, thereby improving work efficiency.

[0015] Optionally, the mounting assembly includes a fixing plate fixedly connected to the side of the mounting plate near the tool, and a stabilizing plate slidably connected to the mounting plate on the lower side of the fixing plate. A hydraulic cylinder is provided on the lower side of the mounting plate to drive the stabilizing plate toward or away from the fixing plate.

[0016] By adopting the above technical solution, the fixing plate overlaps the upper side of the conveyor belt frame, and the hydraulic cylinder drives the stabilizing plate to move and approach the fixing plate until the stabilizing plate abuts against the lower side of the frame. Thus, the mounting plate and drive shaft are fixed by clamping the frame with the fixing plate and the stabilizing plate, thereby improving work efficiency.

[0017] Optionally, each end of the drive shaft is sleeved and rotatably connected to a mounting base. The outer cross-section of the mounting base is square and it is slidably connected to the mounting plate along the length of the mounting plate. The upper side of the mounting base is provided with a driving component for driving the mounting base to move.

[0018] By adopting the above technical solution, the driving component drives the mounting base to move the end of the driving shaft along the length of the mounting plate, thereby facilitating the adjustment of the distance between the lower frame of the blade, thus controlling the slotting depth and further reducing the adverse effects on applicability.

[0019] Optionally, the driving component includes a screw with one end rotatably connected to the upper side of the mounting base, the upper end of the screw passing through the mounting plate and threadedly connected to the mounting plate.

[0020] By adopting the above technical solution, rotating the screw drives the mounting base to move the end of the drive shaft and the blade towards or away from the insulation board, which facilitates the adjustment of the distance between the lower frame of the blade, thereby controlling the groove depth and further reducing the adverse effects on applicability.

[0021] Optionally, the drive shaft has an internal air extraction chamber, and the drive shaft has multiple air extraction holes communicating with the air extraction chamber in its circumferential direction. The spacer ring has a through hole communicating with the air extraction holes on its side wall. The end of the drive shaft away from the motor is provided with an air extraction pipe communicating with the air extraction chamber. The air extraction pipe coincides with the rotation axis of the drive shaft, and a pump is installed on the air extraction pipe.

[0022] By adopting the above technical solution, when the motor drives the drive shaft to rotate and the blade makes grooves on the insulation board, the pump draws air from the suction chamber through the suction pipe. This allows the debris generated during grooving to enter the suction chamber through the through hole and the suction hole and be discharged through the suction pipe, which facilitates the collection of debris and improves work efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] Both the blades and spacer rings are sleeved on the drive shaft and mounted on the drive shaft by limiting parts, fixing rings and fixing parts. When it is necessary to adjust the number of slots on the insulation board, the number of blades on the drive shaft is adjusted according to the number of slots, and the number of spacer rings between two adjacent blades is increased or decreased, thereby adjusting the spacing between the slots on the insulation board and reducing the adverse effects on applicability.

[0025] Install the blades and spacer rings on the drive shaft, and fit the retaining rings onto the end of the drive shaft. At this time, the retaining block is inserted into the corresponding retaining ring. Fix the retaining rings to the drive shaft with bolts. When it is necessary to adjust the number of slots on the insulation board, remove the retaining rings and adjust the number of blades and spacer rings on the drive shaft to reduce the adverse effects on applicability.

[0026] When the motor drives the drive shaft to rotate and causes the blade to slot the insulation board, the pump draws air from the air extraction chamber through the air extraction pipe. This allows the debris generated during slotting to enter the air extraction chamber through the through holes and air extraction holes and be discharged through the air extraction pipe, facilitating the collection of debris and improving work efficiency.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a cutting tool for grooving insulation boards. (Refer to...) Figure 1 and Figure 2 A grooving tool for insulation boards includes a drive shaft 1 and a plurality of annular blades 2 arranged along the length of the drive shaft 1. The blades 2 are perpendicular to the length of the drive shaft 1 and are all sleeved on the drive shaft 1. A spacer ring 21 sleeved on the drive shaft 1 is provided between adjacent blades 2. The drive shaft 1 is provided with limiting members that correspond one-to-one with the blades 2 and the spacer rings 21 and are limited in the circumferential direction of the drive shaft 1.

[0033] Both ends of the drive shaft 1 are fitted with retaining rings 22, and the drive shaft 1 is provided with fasteners that correspond one-to-one with the retaining rings 22. Both ends of the drive shaft 1 are provided with vertical mounting plates 3, and both ends of the drive shaft 1 are fitted with mounting seats 31 located on the side of the retaining rings 22 that are far apart from each other. A motor 11 is mounted on one end of the drive shaft 1 and is fixedly connected to the adjacent mounting plate 3.

[0034] Reference Figure 1 and Figure 3 The mounting base 31 is rotatably connected to the end of the drive shaft 1, and the projection of the outer wall of the mounting base 31 in the vertical direction is square. Each mounting plate 3 has a sliding hole 32 adapted to the mounting base 31 at its upper end. The mounting base 31 is inserted into the sliding hole 32 and slidably connected to the mounting plate 3 in the vertical direction. Each mounting plate 3 is provided with a driving component for moving the mounting base 31. In this embodiment, the driving component is a vertical screw 33 corresponding to each mounting base 31. The lower end of the screw 33 passes through the upper end of the mounting plate 3 and is rotatably connected to the upper side of the mounting base 31. The screw 33 is threadedly connected to the upper end of the mounting plate 3. Each mounting plate 3 has a mounting assembly 4 at its lower end for mounting the drive shaft 1 on the upper side of the conveyor belt.

[0035] Both the blade 2 and the spacer ring 21 are sleeved on the drive shaft 1 and are installed on the drive shaft 1 by a limiting member, a fixing ring 22 and a fixing member. When it is necessary to adjust the number of slots on the insulation board, the number of blades 2 on the drive shaft 1 is adjusted according to the number of slots, and the number of spacer rings 21 between two adjacent blades 2 is increased or decreased, thereby adjusting the spacing between the slots on the insulation board.

[0036] The mounting plate 3 is fixed by the mounting component 4, which facilitates the installation of the drive shaft 1 and the cutting blade 2 to slot the insulation board conveyed on the conveyor belt. The screw 33 is rotated to drive the mounting base 31 to move the end of the drive shaft 1 and the cutting blade 2 toward or away from the insulation board, which facilitates the adjustment of the distance between the lower frame of the cutting blade 2 and thus controls the slotting depth.

[0037] Reference Figure 2 The limiting component includes a limiting block 12 fixedly connected to the side wall of the drive shaft 1 and arranged along the length direction of the drive shaft 1. The limiting blocks 12 are arranged sequentially and integrally formed. The inner side walls of the blade 2 and the spacer ring 21 are provided with through holes 23 adapted to the limiting block 12. When the blade 2 and the spacer ring 21 are installed on the drive shaft 1, the limiting block 12 is inserted into the corresponding through hole 23.

[0038] The fastener includes a fixing block 13 that is fixedly connected to the drive shaft 1 and is arranged along the length of the drive shaft 1. The fixing block 13 and the limiting block 12 are integrally formed. When the fixing ring 22 is installed on the drive shaft 1, the fixing block 13 is inserted into the inner wall of the fixing ring 22, and the fixing ring 22 is fixedly connected to the drive shaft 1 by bolts.

[0039] Install the blade 2 and spacer ring 21 on the drive shaft 1. At this time, the limit block 12 is inserted into the through hole 23. When the motor 11 drives the drive shaft 1 to rotate, the drive shaft 1 drives the blade 2 to rotate through the limit block 12. The fixing ring 22 is sleeved on the end of the drive shaft 1. At this time, the fixing block 13 is inserted into the corresponding fixing ring 22. The fixing ring 22 is fixed on the drive shaft 1 by bolts. When it is necessary to adjust the number of slots on the insulation board, remove the fixing ring 22 and adjust the number of blades 2 and spacer rings 21 on the drive shaft 1.

[0040] Reference Figure 1 and Figure 3 The mounting assembly 4 includes a horizontal fixing plate 41 fixedly connected to the lower end of the mounting plate 3 and close to the blade 2. A horizontal stabilizing plate 42 is provided on the lower side of the fixing plate 41. The ends of the stabilizing plates 42 that are far apart from each other are inserted into the mounting plate 3 and slidably connected to the mounting plate 3 in the vertical direction. A vertical hydraulic cylinder 43 is fixedly connected to the lower end of the mounting plate 3. The telescopic rod of the hydraulic cylinder 43 is fixedly connected to the lower side of the stabilizing plate 42.

[0041] The fixing plate 41 overlaps the upper side of the conveyor belt frame. The hydraulic cylinder 43 drives the stabilizing plate 42 to move and approach the fixing plate 41 until the stabilizing plate 42 abuts against the lower side of the conveyor belt frame. Thus, the mounting plate 3 and the drive shaft 1 are fixed by clamping the conveyor belt frame with the fixing plate 41 and the stabilizing plate 42.

[0042] The drive shaft 1 has an internal suction chamber 14 arranged along its length. Multiple suction holes 15 communicating with the suction chamber 14 are provided on the outer wall of the drive shaft 1. Multiple through holes 211 communicating with the suction holes 15 are provided on the spacer ring 21. When the spacer ring 21 is installed on the drive shaft 1, the suction holes 15 communicate with the through holes 211. A suction pipe 5 communicating with the suction chamber 14 is fixedly connected to the end of the drive shaft 1 away from the motor 11. In this embodiment, the suction pipe 5 is a flexible hose, and a pump 51 for evacuating air from the suction chamber 14 is installed on the suction pipe 5.

[0043] When the motor 11 drives the blade 2 to slot the insulation board through the drive shaft 1, the pump 51 draws air from the suction chamber 14 through the suction pipe 5. The debris generated during slotting enters the suction chamber 14 through the through hole 211 and the suction hole 15 and is discharged through the suction pipe 5, which facilitates the collection of debris.

[0044] The implementation principle of a grooving tool for insulation board according to an embodiment of this application is as follows: the blade 2 and the spacer ring 21 are installed on the drive shaft 1. At this time, the limiting block 12 is inserted into the through hole 23. When the motor 11 drives the drive shaft 1 to rotate, the drive shaft 1 drives the blade 2 to rotate through the limiting block 12. The fixing ring 22 is sleeved on the end of the drive shaft 1. At this time, the fixing block 13 is inserted into the corresponding fixing ring 22. The fixing ring 22 is fixed on the drive shaft 1 by bolts. When it is necessary to adjust the number of grooves on the insulation board, the fixing ring 22 is removed and the number of blades 2 and spacer rings 21 on the drive shaft 1 are adjusted.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
