Description

Technical Field

[0001] The present invention relates to the technical field of grooving, in particular to a polystyrene foam board surface grooving device and a use method thereof. Background Art

[0002] Polystyrene foam board is a closed-cell polystyrene foam plastic sheet made by pre-foaming expandable polystyrene beads by heating and then forming them in a mold. The raw materials undergo a series of processes, including pre-expansion, aging, forming, drying, and cutting. It can be made into foam products of varying densities and shapes, as well as various thicknesses. It is widely used in construction, insulation, packaging, refrigeration, daily necessities, industrial casting, and other fields. To meet specific application requirements, polystyrene foam board requires surface grooves.

[0003] In the existing equipment for grooving the surface of polystyrene foam boards, the grooved heating wires are exposed to the outside, and the grooved heating wires have a certain temperature after being heated. If the workers accidentally touch them, they may be scalded, which reduces the safety of use. In addition, the grooved heating wires may be adhered to impurities after grooving. If the impurities on the grooved heating wires are not cleaned, the flatness of the grooves of the grooved heating wires will be reduced next time, which reduces the effect of use. Therefore, it is urgent to redesign a polystyrene foam board surface grooving equipment to solve the problems of unsafe and uneven grooving when grooving polystyrene foam boards.

[0016] A method for using a polystyrene foam board surface grooving device comprises the following steps:

[0017] S1: First, place the polystyrene foam board on top of the bottom plate and heat the slotted heating wire. The first motor drives the screw to rotate, which drives the two slides to move. The movement of the two slides moves the movable rod. The movement of the two movable rods drives the first slide to move downward. The downward movement of the first slide drives the movable block and the folding rod to move downward. The downward movement of the folding rod drives the pressing plate to move downward. The downward movement of the pressing plate presses the polystyrene foam board tightly.

[0018] S2: The movable block moves downward, causing the protective box, telescopic sleeve and electric telescopic rod to move downward. The downward movement of the protective box will drive the connecting parts thereon to move downward, namely the three gears, belt, pulley, pulley, square block, brush roller, slotted heating wire and friction disk. The third gear moves downward, meshing with one of the racks and causing the third gear to rotate. The rotation of the third gear will drive the first pulley, the second belt, the second pulley, the pulley and the first belt to rotate. The rotation of one of the pulleys will drive the square block to rotate. The rotation of the square block will drive the three slotted heating wires to rotate, so that one of the slotted heating wires can face downward to facilitate subsequent slotting. In addition, the rotation of the second pulley will drive the first gear to rotate. The rotation of the first gear will rotate the second gear. The rotation of the second gear will drive the brush roller to rotate. The rotation of the brush roller will clean the slotted heating wire that passes by.

[0019] S3: When the protective box moves to the bottom, the second motor drives the lead screw to rotate, and the rotation of the lead screw drives the movable block to move, and the movement of the movable block drives the telescopic sleeve to move and the protective box to move horizontally. The horizontal movement of the protective box drives the square block and the slotted heating wire to move, so that the polystyrene foam board can be slotted, and the vertical plate and the three racks can move horizontally with the protective box. When it is necessary to slot different depths of the polystyrene foam board, it is only necessary to drive the push plate to move by the electric telescopic rod, and the movement of the push plate will drive the second slide to move, and the movement of the second slide will drive the vertical plate and the three racks to move, so that other racks can be replaced and engaged with the third gear, so that the square block can be rotated to different angles (90°, 180° and 270°) so that different slotted heating wires are slotted downward.

[0020] The beneficial effects of the present invention are:

[0021] First, the present invention, through the provision of a protective box, a square block and a vertical plate, can shield the slotted heating wire when not in use, thereby ensuring safety in use. In addition, the position of the square block can be adjusted according to the required slot depth to adjust the slotted heating wire to face downward, thereby increasing the range of use of the device.

[0022] Secondly, the present invention can clean the adherents on the surface of the slotted heating wire by setting the brush roller and the connecting box, thereby ensuring the neatness of the groove edge of the next slotting of the polystyrene foam board and improving the quality of the slotting of the polystyrene foam board;

[0023] Thirdly, the present invention can press the polystyrene foam board placed on the bottom plate by setting the pressing plate, ensuring that the polystyrene foam board will not move when the slotting heating wire slots the polystyrene foam board, thereby improving the accuracy of slotting the polystyrene foam board.

10. The method for using the polystyrene foam board surface grooving device according to claim 9, characterized in that: The following steps are involved: S1: First, a polystyrene foam board is placed on the top of the bottom plate (1) and the slotted heating wire (21) is heated. The first motor (3) drives the screw rod (7) to rotate. The rotation of the screw rod (7) drives the two slides (8) to move. The movement of the two slides (8) moves the movable rod (9). The movement of the two movable rods (9) drives the first slide (16) to move downward. The downward movement of the first slide (16) drives the movable block (30) and the folding rod (5) to move downward. The downward movement of the folding rod (5) drives the pressing plate (4) to move downward. The downward movement of the pressing plate (4) presses the polystyrene foam board tightly. S2: The movable block (30) moves downward, causing the protective box (6), the telescopic sleeve (26) and the electric telescopic rod (22) to move downward. The protective box (6) moves downward, which drives the connecting components thereon to move downward (three gears, belts, pulleys (14), pulleys, square blocks (11), brush rollers (19), slotted heating wires (21) and friction discs (20)). The third gear (33) moves downward, meshing with one of the racks (31) and causing the third gear (33) to rotate. The rotation of the third gear (33) drives the first pulley (34), the second belt (36), the second pulley ( 35), the pulley (14) and the first belt (13) rotate, the rotation of one of the pulleys (14) drives the square block (11) to rotate, the rotation of the square block (11) drives the three slotted heating wires (21) to rotate, so that one of the slotted heating wires (21) can be turned downward to facilitate subsequent slotting, and the rotation of the second pulley (35) drives the first gear (15) to rotate, the rotation of the first gear (15) drives the second gear (27) to rotate, the rotation of the second gear (27) drives the brush roller (19) to rotate, and the rotation of the brush roller (19) cleans the slotted heating wire (21) passing by; S3: When the protective box (6) moves to the bottom, the second motor (29) drives the lead screw (28) to rotate, and the rotation of the lead screw (28) drives the movable block (30) to move, and the movement of the movable block (30) drives the telescopic sleeve (26) to move and the protective box (6) to move horizontally. The horizontal movement of the protective box (6) drives the square block (11) and the slotted heating wire (21) to move, so that the polystyrene foam board can be slotted, and the vertical plate (12) and the three racks (31) can move horizontally with the movement of the protective box (6). When it is necessary to open grooves of different depths on the polystyrene foam board, it is only necessary to drive the push plate (32) to move through the electric telescopic rod (22). The movement of the push plate (32) will drive the second slide (24) to move. The movement of the second slide (24) will drive the vertical plate (12) and the three racks (31) to move, so that other racks (31) and the third gear (33) can be engaged, so that the square block (11) can be rotated to different angles (90°, 180° and 270°) to make different slotted heating wires (21) face downward to open the grooves.
