Description

Technical Field

[0001] This application relates to the field of cutting equipment, and in particular to a cutting device for insulation boards. Background Technology

[0002] Insulation boards are boards used for building insulation. They are made from polystyrene resin and other raw materials and polymers, forming a plastic board with moisture-proof and waterproof properties. This allows for a reduction in the thickness of the building's external envelope, thereby increasing usable indoor space.

[0003] When splicing insulation boards, the boards are usually judged and cut manually. However, manual operation lacks precision, so there is a possibility that the joints of the insulation boards may be uneven and misaligned. Utility Model Content

[0004] To improve the flatness and alignment of the joints of insulation boards, this application provides an insulation board edge cutting device.

[0005] The insulation board trimming device provided in this application adopts the following technical solution: An insulation board trimming device includes a rotating shaft, a connecting sleeve detachably connected to the rotating shaft, a blade cylinder detachably connected to the outside of the connecting sleeve, and a cutting blade mounted on the outside of the blade cylinder.

[0006] By adopting the above technical solution, the rotating shaft rotates, thereby driving the connecting sleeve, the blade cylinder and the cutter to rotate. When the cutter needs to be replaced, the blade cylinder can be disassembled to quickly replace it with a cutter of the same specification. The connecting sleeve can be disassembled to replace it with a cutter of a different specification. This allows for the application of different cutting sizes. The cutter cuts grooves at the edge of the insulation board, and the grooves of the insulation board interlock with each other, thereby allowing for the splicing of seams with the same grooves, thus improving neatness.

[0007] Optionally, one end of the cutter barrel is provided with a mounting plate, which abuts against the end face of the connecting sleeve, and the end face of the connecting sleeve is provided with a plurality of evenly distributed positioning rods, which pass through the mounting plate and are threadedly connected to positioning nuts that abut against the mounting plate.

[0008] By adopting the above technical solution, the mounting plate abuts against the end face, and the positioning rod passes through the mounting plate to position the mounting plate. The positioning nut on the positioning rod fixes the mounting plate to the connecting sleeve, thereby fixing the cutter cylinder to the connecting sleeve.

[0009] Optionally, the rotating shaft passes through the connecting sleeve and the mounting plate. A keyway is provided on the inner side of the connecting sleeve. A flat key is provided on the rotating shaft and inserted into the keyway. A stop block is abutted at the end of the connecting sleeve away from the mounting plate. The stop block is fixedly connected to the rotating shaft. A fixing nut is threaded onto the rotating shaft and abuts against the mounting plate.

[0010] By adopting the above technical solution, the stop block and the fixing nut are fixedly connected to the rotating shaft, and the rotating shaft is connected to the connecting sleeve through a flat key, thereby driving the connecting sleeve to rotate synchronously with the rotating shaft.

[0011] Optionally, the blade cylinder is provided with a plurality of evenly distributed suction holes, the connecting sleeve is provided with a cavity communicating with the suction holes, and the rotating shaft is provided with a suction assembly communicating with the cavity.

[0012] By adopting the above technical solution, when the cutter barrel rotates and cuts the insulation board, the suction component works, so that the debris on the insulation board enters the cavity through the system's air control and moves along the cavity toward the suction component, thereby quickly collecting the waste debris.

[0013] Optionally, the suction assembly includes a housing disposed outside the rotating shaft, a fan disposed inside the housing, and the fan being coaxially mounted on the rotating shaft.

[0014] By adopting the above technical solution, the rotating shaft rotates while driving the fan to rotate, thereby allowing the external airflow to enter the cavity through the air intake hole and flow towards the fan.

[0015] Optionally, the housing is provided with a partition plate and a baffle plate, the fan is mounted on the partition plate, the baffle plate is located between the fan and the connecting sleeve, a filter cloth is provided between the partition plate and the baffle plate, and an air outlet is provided on the housing, with the air outlet located on the side of the partition plate away from the baffle plate.

[0016] By adopting the above technical solution, the waste debris enters the box with the airflow, the airflow passes through the filter cloth and flows out at the air outlet. At this time, the waste debris is blocked by the filter cloth, thus allowing the waste debris to be collected in the box.

[0017] Optionally, a chip discharge port is provided at the lower end of the box, and a collection box can be detachably connected to the chip discharge port.

[0018] By adopting the above technical solution, the waste enters the collection box, and when the collection box is disassembled, the waste can be quickly cleaned up.

[0019] Optionally, a drive fan is provided on the side of the partition away from the baffle, the drive fan is rotatably connected to the housing, a knocking rod is hinged on the side of the partition near the baffle, one end of the knocking rod is provided with a spring, the other end abuts against a wedge, the wedge is slidably connected to the housing, a drive gear is fixed below the wedge, and the wedge is located at the eccentric position of the drive gear, and a gear set connecting the drive fan and the drive gear is provided between the two.

[0020] By adopting the above technical solution, during the process of airflow out of the air outlet, the airflow drives the drive fan to rotate, and the drive fan drives the drive gear to rotate through the gear set. The wedge on the drive gear squeezes the knocking rod once during each circumferential motion, so that the knocking rod can knock the filter cloth and clean the filter cloth.

[0021] In summary, this application includes at least one of the following beneficial technical effects: When it is necessary to replace the cutter, the same specification cutter can be quickly replaced by disassembling the cutter tube, and different specifications cutters can be replaced by disassembling the connecting sleeve. This allows for the application of different cutting sizes. The cutter cuts grooves at the edge of the insulation board, and the grooves of the insulation board interlock with each other, thus allowing for the splicing of seams with the same grooves, thereby improving neatness. As the cutter barrel rotates and cuts the insulation board, the suction assembly operates, causing the debris on the insulation board to enter the cavity through the system's air control and move along the cavity toward the suction assembly, thereby quickly collecting the waste debris.

[0027] The present application will be further described in detail below with reference to the accompanying drawings. Example

[0028] This application discloses an insulation board trimming device. (Refer to...) Figure 1 and Figure 2 An insulation board edge cutting device includes a rotating shaft 1, one end of which is coaxially fixedly connected to a drive motor, and the other end of the rotating shaft 1 is detachably connected to a connecting sleeve 2. A blade cylinder 3 is detachably connected to the outside of the connecting sleeve 2, and a cutting blade 31 is installed on the outside of the blade cylinder 3.

[0029] When the insulation board needs to be trimmed, the drive motor drives the rotating shaft 1 to rotate, thereby driving the connecting sleeve 2, the knife cylinder 3, and the cutter 31 to rotate. The insulation board moves along the length of its edge, thereby cutting a groove at the edge of the insulation board. This allows two insulation boards to be interlocked through the groove, improving the neatness of the joint. When the cutter 31 needs to be replaced, the same specification cutter 31 can be quickly replaced by disassembling the knife cylinder 3. Different specifications of cutters 31 can be replaced by disassembling the connecting sleeve 2, thus making it suitable for different cutting sizes.

[0030] A mounting plate 32 is fixed to one end of the cutter barrel 3. The mounting plate 32 abuts against the end face of the connecting sleeve 2 and is recessed into the connecting sleeve 2. Multiple evenly distributed positioning rods 21 are provided on the end face of the connecting sleeve 2. The positioning rods 21 pass through the mounting plate 32. Positioning nuts 22 are threaded onto the positioning rods 21. The positioning nuts 22 abut against the side wall of the mounting plate 32 away from the connecting sleeve 2.

[0031] Mounting plate 32 abuts against the end face, and positioning rod 21 passes through mounting plate 32, thereby positioning mounting plate 32. Positioning nut 22 on positioning rod 21 fixes mounting plate 32 to connecting sleeve 2, thus the cutter barrel 3 is fixedly mounted on connecting sleeve 2.

[0032] The rotating shaft 1 passes through the connecting sleeve 2 and the mounting plate 32. A keyway is provided on the inner side of the connecting sleeve 2. A flat key 13 is provided on the rotating shaft 1 and inserted into the keyway. A stop block 11 is abutted at the end of the connecting sleeve 2 away from the mounting plate 32. The stop block 11 is fixedly connected to the rotating shaft 1. A fixing nut 12 is threaded onto the rotating shaft 1 and abuts against the mounting plate 32. The stop block 11 and the fixing nut 12 cooperate to fix the connecting sleeve 2 on the rotating shaft 1. At the same time, the rotating shaft 1 is connected to the connecting sleeve 2 through the flat key 13, thereby driving the connecting sleeve 2 to rotate synchronously with the rotating shaft 1. Example

[0033] The difference from Example 1 is that, referring to Figure 3 and Figure 4To facilitate the collection of cutting debris, multiple evenly distributed suction holes 33 are provided on the cutter barrel 3. The suction holes 33 are designed as oblong holes. A cavity communicating with the suction holes 33 is provided inside the connecting sleeve 2. A suction assembly 4 connecting the cavity is provided on the rotating shaft 1. When the cutter barrel 3 rotates and cuts the insulation board, the suction assembly 4 works, causing the debris on the insulation board to enter the cavity through the system's air control and move along the cavity toward the suction assembly 4, thereby quickly collecting the debris.

[0034] The suction assembly 4 includes a housing 41 located outside the rotating shaft 1. The housing 41 is fixedly connected to the housing of the drive motor. Multiple ventilation pipes 413, evenly distributed around the rotating shaft 1, are fixed on the housing 41. The ventilation pipes 413 communicate with the cavity and are slidably connected to the connecting sleeve 2. A partition plate 42 is fixedly connected inside the housing 41, separating the interior of the housing 41. A fan 43 is mounted on the partition plate 42, and the fan 43 is coaxially mounted on the rotating shaft 1. A baffle 44 is also provided between the partition plate 42 and the connecting sleeve 2. The baffle 44 is fixedly connected to the housing 41, and an opening is provided between the end of the baffle 44 away from the rotating shaft 1 and the inner wall of the housing 41. A filter cloth 45 is installed between the end of the baffle 44 near the opening and the partition plate 42. An air outlet is provided on the housing 41, located on the side of the partition plate 42 away from the baffle 44.

[0035] As the rotating shaft 1 rotates, it drives the fan 43 to rotate, thereby causing the external airflow to enter the cavity along the air intake hole 33 and flow toward the fan 43. Waste debris enters the housing 41 with the airflow. The airflow passes through the filter cloth 45 and flows out at the air outlet. At this time, the waste debris is blocked by the filter cloth 45, thus allowing the waste debris to be collected in the housing 41.

[0036] The lower end of the housing 41 has a chip discharge port 411, and a collection box 412 is provided at the chip discharge port 411. The collection box 412 is threadedly connected to the housing 41. Waste chips enter the collection box 412, and when the collection box 412 is removed, the waste chips can be quickly cleaned up.

[0037] To reduce the cleaning frequency of the filter cloth 45, a tapping assembly 5 is also provided in the housing 41. The tapping assembly 5 includes a drive fan 51, which is installed on the side of the partition plate 42 away from the baffle 44. The drive fan 51 is rotatably connected to the housing 41. A tapping rod 52 is hinged to the side of the partition plate 42 near the baffle 44. One end of the tapping rod 52 is equipped with a spring 53, and the other end abuts against a wedge 54. The wedge 54 is slidably connected to the housing 41. A drive gear 55 is fixed below the wedge 54, and the wedge 54 is located at an eccentric position of the drive gear 55. A coaxial drive gear is fixed to the outside of the drive fan 51. The drive gear and the drive gear 55 are connected by a gear set. During the airflow out of the air outlet, the airflow drives the drive fan 51 to rotate. The drive fan 51 drives the drive gear 55 to rotate through the gear set. The wedge 54 on the drive gear 55 squeezes the tapping rod 52 once with each circumferential motion, so that the tapping rod 52 can tap the filter cloth 45, thereby cleaning the filter cloth 45.

[0038] The implementation principle of the insulation board edge cutting device in this application embodiment is as follows: the drive motor drives the rotating shaft 1 to rotate, thereby driving the cutter 31 to rotate, thereby cutting the side of the insulation board. The debris cut off from the insulation board enters the suction hole 33 with the airflow, enters the box 41 along the cavity, is filtered by the filter cloth 45, and is finally collected in the collection box 412.

[0039] 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.
