Description

Technical Field

[0001] The utility model relates to the technical field of sheet processing machinery and equipment, in particular to a heat-insulating sheet grooving machine. Background Art

[0002] The heat-insulating sheet is a rigid sheet made of polystyrene resin as the raw material, plus other auxiliary materials and polymers, and has excellent heat-insulating performance. In the production, manufacturing, storage and transportation of heat-insulating sheets, cutting, bending, etc. of heat-insulating sheets are common processing technologies. Before bending the sheet, it is necessary to groove the sheet first to improve the convenience of sheet bending and reduce the probability of fracture when the heat-insulating sheet is bent.

[0003] In the related art, reference can be made to the Chinese utility model patent with the authorization publication number of CN206953109U, which discloses an automatic grooving machine for EPE sheets, including a machine frame, a feeding rotating shaft, a feeding control mechanism, an electric heating grooving mechanism, and an electric control system. The machine frame constitutes the accommodating cavity and the rigid support frame of the grooving machine. The feeding rotating shaft is embedded in the accommodating cavity. The feeding control mechanism provides a feeding path for the EPE sheet and controls the feeding speed. The electric heating grooving mechanism is arranged in the middle of the feeding control mechanism and is responsible for grooving the sheet with the set length, width and depth dimensions at the set position. The electric control system is responsible for the control of the feeding speed, electric heating power, and feeding direction; the feeding control mechanism includes a guiding block and a trumpet-shaped feeding and discharging port.

[0004] The sheet enters the feeding control mechanism from the trumpet-shaped feeding and discharging port and advances along the feeding groove surrounded by the guiding block. The feeding rotating shaft sends the sheet to the electric heating grooving mechanism for grooving operation. After grooving, the sheet is output under the action of the feeding rotating shaft. However, the corner materials generated by grooving will wind around the feeding rotating shaft or the grooving mechanism as the feeding rotating shaft rotates, which has an adverse effect on the grooving of the sheet by the grooving machine and reduces the grooving effect of the heat-insulating sheet. Summary of the Utility Model

[0005] In order to improve the grooving effect of the heat-insulating sheet, the utility model provides a heat-insulating sheet grooving machine.

[0006] A heat-insulating sheet grooving machine provided by this application adopts the following technical scheme:

[0007] A heat-insulating sheet grooving machine includes a machine frame, a conveyor belt arranged on the machine frame, a grooving assembly and a limiting assembly. The grooving assembly is located above the conveyor belt. The conveyor belt is used for conveying the sheet. The grooving assembly is used for cutting the sheet. The limiting assembly is used for positioning the sheet on the conveyor belt.

[0008] By adopting the above technical solution, the conveyor belt drives the board to move. When the board moves below the grooving assembly, the grooving assembly starts to groove the board, and the limiting assembly positions the board, reducing the probability of the ungrooved board shifting during the grooving process and at the same time reducing the probability of the corner material generated at the grooving position on the board winding around the grooving assembly, thereby improving the grooving effect of the insulation board.

[0009] Optionally, the grooving assembly includes:

[0010] A mounting plate which is arranged on the frame and above the conveyor belt;

[0011] A rotating shaft which is rotatably arranged on the mounting plate and extends horizontally. The extending direction of the rotating shaft is perpendicular to the conveying direction of the conveyor belt, and a rotating motor for driving the rotating shaft to rotate is arranged on the mounting plate;

[0012] Two grooving knives which are coaxially arranged on the rotating shaft, and the distance between the two grooving knives is equal to the width of the groove required for the board.

[0013] By adopting the above technical solution, when the rotating motor starts, it drives the rotating shaft to rotate. The rotating shaft drives the grooving knives to rotate, and the grooving knives rotate to groove the insulation board, thereby realizing the grooving process of the insulation board.

[0014] Optionally, the limiting assembly includes:

[0015] A mounting shaft which is arranged on the mounting plate and parallel to the rotating shaft;

[0016] A first pressing plate, one end of which is arranged on the mounting shaft, and the other end of the first pressing plate extends below the grooving knife and elastically presses on the grooving corner material.

[0017] By adopting the above technical solution, when the insulation board moves, the first pressing plate elastically presses against the part of the board located between the two grooving knives. When the grooving knives rotate to groove the board, the cut corner material stays in the groove under the pressing action of the first pressing plate and will not curl and wind around the grooving knife or the mounting shaft as the board moves, thereby reducing the probability of the grooving corner material having an adverse effect on grooving and thus improving the grooving effect of the insulation board.

[0018] Optionally, a second pressing plate for limiting the board is further arranged on the mounting shaft, and the second pressing plate elastically presses on the board.

[0019] By adopting the above technical solution, when the insulation board moves, the second pressing plate elastically presses against the part of the ungrooved insulation board, reducing the probability of the board shifting during the cutting process. Cooperating with the first pressing plate, it improves the cutting stability of the board, thereby improving the grooving effect of the insulation board.

[0020] Optionally, a lifting mechanism for driving the slotting cutter to lift is provided on the frame. The lifting mechanism includes:

[0021] A mounting frame, which is fixedly provided on the frame and covers above the conveyor belt, and the mounting plate is vertically slidably arranged in the mounting frame;

[0022] A lifting lead screw, which is rotatably arranged on the mounting frame and extends vertically;

[0023] A connecting block, which is arranged on the mounting plate and is threadedly connected with the lifting lead screw;

[0024] A lifting motor, which is arranged on the mounting frame and is in transmission connection with the lifting lead screw.

[0025] By adopting the above technical solution, when the lifting motor starts, it drives the lifting lead screw to rotate. The rotation of the lifting lead screw drives the mounting plate to vertically slide in the mounting frame, and the movement of the mounting plate drives the slotting cutter to lift, so as to be adapted to slotting plates with different thicknesses, thereby improving the convenience of slotting the thermal insulation plates.

[0026] Optionally, the lifting lead screw includes a first lead screw and a second lead screw. There are two connecting blocks, which respectively correspond to the first lead screw and the second lead screw. A first bevel gear is coaxially and fixedly provided at the upper end of the first lead screw, and a second bevel gear is coaxially and fixedly provided at the upper end of the second lead screw. A synchronizing rod extending horizontally is provided on the frame. One end of the synchronizing rod is in transmission connection with the lifting motor. A third bevel gear and a fourth bevel gear are coaxially and fixedly provided on the synchronizing rod. The third bevel gear meshes with the first bevel gear, and the fourth bevel gear meshes with the second bevel gear.

[0027] By adopting the above technical solution, when the lifting motor starts, it drives the synchronizing rod to rotate. The synchronizing rod drives the third bevel gear and the fourth bevel gear to rotate. The third bevel gear drives the first lead screw to rotate through the first bevel gear, and the fourth bevel gear drives the second lead screw to rotate through the second bevel gear. The rotation of the second lead screw and the first lead screw drives the mounting plate to lift synchronously, and both ends of the rotating shaft lift synchronously, so that the two slotting cutters are always on the same horizontal line, improving the convenience and stability of the lifting of the slotting cutter, and thus improving the convenience and slotting effect of slotting the thermal insulation plates.

[0028] Optionally, a mounting seat is coaxially and slidably sleeved on the rotating shaft. The slotting cutter is coaxially and fixedly provided on the mounting seat. A positioning bolt for locking the mounting seat is threadedly connected to the mounting seat.

[0029] By adopting the above technical solution, unlocking the positioning bolt and then moving the position of the mounting seat can adjust the width of the slot, thereby improving the convenience of adjusting the slot width.

[0030] Optionally, a guiding plate extending along the conveying direction of the conveyor belt is provided on the frame. When conveying the board, the edge of the board is in sliding fit with the guiding plate, and an adjusting assembly for adjusting the position of the guiding plate is provided on the frame.

[0031] By adopting the above technical solution, the distance between the guiding plate and the frame is adjusted according to the width of the heat-insulating board. The conveyor belt drives the board to move, and the edge of the board fits with the guiding plate, thereby limiting the moving direction of the board. The board is positioned through the cooperation of the guiding plate, the first pressing plate and the second pressing plate, improving the stability of the board moving for grooving, and thus improving the grooving effect of the heat-insulating board.

[0032] Optionally, two guiding plates are provided and are respectively located on both sides of the mounting plate. The adjusting assembly includes:

[0033] An adjusting column, which is provided on the frame and has through holes penetrating both side walls of the adjusting column;

[0034] A guiding rod, which is fixedly provided on the guiding plate and extends horizontally. The end of the guiding rod away from the guiding plate slides through the through hole, and an adjusting handle for positioning the guiding rod is threadedly connected to the adjusting column.

[0035] By adopting the above technical solution, turn the adjusting handle away from the guiding rod, then move the guiding rod to adjust the position of the guiding plate. After moving in place, turn the adjusting handle to position the guiding rod, thereby realizing the adjustment and positioning of the guiding plate.

[0036] Optionally, a protective cover for protecting the grooving knife is provided on the mounting plate.

[0037] By adopting the above technical solution, the protective cover protects the grooving knife, reducing the probability of the grooving knife hurting people and at the same time reducing the probability of external materials having an adverse impact on the operation of the grooving knife.

[0038] In summary, the present application includes at least one of the following beneficial technical effects:

[0039] 1. The conveyor belt drives the heat-insulating board to move. The board moves below the grooving assembly, and the grooving assembly starts to groove the board. The limiting assembly positions the board, reducing the probability of the un-grooved board shifting during the grooving process and at the same time reducing the probability of the corner material generated at the grooving position on the board winding around the grooving assembly, thereby improving the grooving effect of the heat-insulating board.

[0040] 2. When the heat preservation board moves, the first pressing plate elastically presses against the part of the board located between the two grooving knives. When the grooving knives rotate to groove the heat preservation board, the cut-off waste stays in the groove under the pressing action of the first pressing plate and will not curl and wind around the grooving knives or the mounting shafts as the board moves, thereby reducing the probability of the cut-off waste having an adverse effect on grooving and improving the grooving effect of the heat preservation board.

[0041] 3. When the heat preservation board moves, the second pressing plate elastically presses against the un-grooved part of the board, reducing the probability of the board shifting during the cutting process. Cooperating with the first pressing plate, it improves the stability of the board cutting, thereby improving the grooving effect of the heat preservation board. Description of the Drawings
