Description

Technical Field

[0001] The present application relates to the technical field of slotting equipment, and in particular to a cutting tool for a mineral wool board step-down slotting machine. Background Art

[0002] Mineral wool boards are commonly used for ceiling and wall decoration, particularly in office buildings and commercial centers. During production, they are typically grooved and stepped to create a stepped structure for easier assembly. This allows the boards to form a staggered, layered structure within the ceiling or wall, achieving both functional and decorative qualities.

[0003] Because step-down grooving has a non-planar, three-dimensional structure formed by a stepped, layered design, multiple sets of cutting blades are typically located on different planes on either side of the cutting line. Because the depth and shape of the cuts vary significantly at each location, different cutting speeds are required. However, the workpiece's movement speed along the cutting line doesn't adjust with the workpiece's arrival position. Therefore, the workpiece's movement speed along the cutting line typically adapts to the slowest cutting speed, limiting processing efficiency. Summary of the Invention

[0004] The present application proposes a cutting tool for a mineral wool board grading and grooving machine, which is provided with two sets of cutting heads and can actively move and reset, so that the cutting head with a slower cutting speed can adapt to the faster cutting line running speed, thereby increasing the upper limit of the cutting line speed and improving the grooving speed.

[0006] Furthermore, the two groups of cutting heads are connected into a whole through a connecting rod, the slider is movably connected to the cutting head through a rotating table, and the spacing of the splints is adapted to the length of the connecting rod, so that each time the slider rotates around the cutting head, the slider can always be stuck in the drive belt, and the reset device can drive one side to rotate around the other side to achieve reset, and the rotation plane is perpendicular to the rotation axis of the cutting head.

[0009] Furthermore, when the sensing blade of the cutting head sensing device, which is relatively positioned opposite to the running direction of the cutting line, contacts the mineral wool board, the timing starts. After the countdown of t hours, the cutting head drives the cutting head on the other side to rotate to the other end.

[0010] Furthermore, a monitor is provided on the support platform, which can detect the overall offset of the cutting head and the connecting rod. If there is an overall offset of the cutting head, the value of t is adjusted by gradually increasing or decreasing one unit to adjust the overall offset direction of the cutting head so that the operating range of the cutting head remains roughly unchanged.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1, as Figure 1-Figure 3, a cutting tool for a mineral wool board grading and grooving machine, wherein one side of the cutting line 1 is provided with 1-3 groups of cutting units 3, the cutting unit 3 includes a support table 307 and a cutting head 301, the support table 307 is installed on the cutting machine frame on the side of the cutting line 1, the support table 307 is connected to a driving device 309, the driving device 309 can be a cylinder, the driving device 309 drives the support table 307 to move, so that it moves away from or close to the cutting line 1 to adjust the cutting depth, a driving belt 305 is installed on the support table 307, the driving belt 305 rotates at a set speed, the support table 307 is a hollow box body, and notches are provided at both ends of the driving belt 305. The driving belt 305 passes through the notch so that a part of the driving belt 305 is above the support table 307 and moves along the upper surface of the support table 307. The driving structure of the driving belt 305 is located inside the support table 307, and the driving belt 305 is provided with a clamping plate 306. The clamping plate 306 is fixed to the driving belt 305 by fastening screws. There are two groups of cutting heads 301 connected as a whole by a connecting rod 302. A slider 303 is provided at the bottom of the cutting head 301. The slider 303 slides on a support platform 307. The slider 303 is adapted to the driving belt 305 and can be stuck in the driving belt 305, so that the cutting head 301 moves as the driving belt 305 moves. A rotating platform 312 is provided between the driving belt 305 and the cutting head 301. The rotating platform 312 can rotate the connecting rod 302 around the axis of the cutting head 301, thereby allowing the cutting head 301 on one side to rotate around the cutting head 301 on the other side. The spacing of the clamping plates 306 is adapted to the length of the connecting rod 302, so that each time the slider 303 rotates around the cutting head 301, the slider 303 can always be stuck in the driving belt 305. A sensing device is provided on the cutting head 301. The sensing device can sense the cutting state of the cutting head 301. The sensing device can be capacitive or piezoresistive and can sense whether the cutting head 301 is cutting something.

[0028] Length of connecting rod 302 Wherein, L1 is the cutting length of the mineral wool board 4 to be cut, v1 is the running speed of the cutting line 1, v1 adapts to the fastest cutting speed of the cutting blade 2, v2 is the running speed of the drive belt 305, v2 adapts to the cutting speed of the cutting head 301, v1-v2 is the cutting speed of the cutting head 301, v2 / v1<0.5, x is the adjustment margin, and x is half of the gap between the two mineral wool boards 4.

[0029] When the induction blade of the cutting head 301 that is opposite to the running direction of the cutting line 1 contacts the mineral wool board 4, the timing starts. After the countdown t, the cutting head 301 drives the cutting head 301 on the other side to rotate to the other end. After time t, since v2 / v1<0.5, the cutting head 301 on the other side has completed cutting. Since the length of the connecting rod 302 is the same at this time and the sum of the remaining cutting amount of the mineral wool board 4 and x is the same, the cutting head 301 on the other side can be rotated at this time. After reaching the other side of the mineral wool board 4, the relative position of the cutting head 301 remains unchanged, and the cutting can be completed in a continuous cycle.

[0030] In some cases, the gap between the two mineral wool boards 4 may be too large or too small, causing the cutting head 301 to deviate to one side as a whole. A monitor 313 is provided on the support platform 307. The monitor 313 can detect the overall movement of the cutting head 301 and the connecting rod 302. If the cutting head 301 is deviated as a whole, adjustment is required. At this time, the value of t is adjusted by gradually increasing or decreasing one unit to adjust the overall deflection direction of the cutting head 301 so that the operating range of the cutting head 301 remains approximately unchanged. If the gap between the two mineral wool boards 4 is smaller than the actual gap, the cutting head 301 will deviate in the opposite direction of the cutting line. If it is detected that the cutting head 301 is deviated in the opposite direction of the cutting line, the value of t is reduced to make the cutting head 301 move in the opposite direction as a whole. Otherwise, the value of t is increased. The monitor 313 is provided on the swing arm 310. The monitor 313 is a movable resistor. The extension and retraction of the swing arm 310 changes the resistance of the monitor 313. The overall deflection of the cutting head 301 is judged by the deflection of the change range of the resistance on the monitor 313.

[0031] See also Figure 5 The connecting rod 302 is composed of two telescopic shafts 3021. The telescopic shaft 3021 is provided with a locking structure. After the length of the telescopic shaft 3021 is adjusted, it is locked to keep the length unchanged. The motor 304 is arranged between the two telescopic shafts 3021. The motor 304 and the telescopic shaft 3021 are transmission connected. The cutting head 301 is transmission connected to the driven wheel 3023. The telescopic shaft 3021 is connected to the driving wheel 3022. The driving wheel 3022 and the driven wheel 3023 are transmission connected. The driving wheel 3022 and the driven wheel 3023 are both bevel gears. The cutting heads 301 on both sides are driven to rotate at the same time by one motor 304.

[0032] See also Figure 6 A swing arm 310 is provided on one side of the support platform 307. An electric slip ring 311 is provided at the end of the swing arm 310. A protective tube is provided at the bottom of the electric slip ring 311. The swing arm 310 can be extended and retracted to adapt to the movement of the cutting head 301 and the connecting rod 302. The swing arm 310 can also be extended and retracted to adapt to the rotation of the cutting head 301 and the connecting rod 302. The protective tube connects the motor 304 and the electric slip ring 311. The cable passes through the protective tube and is connected to the electric slip ring 311. The cable connected to the electric slip ring 311 passes through the swing arm 310 and is connected to the power supply.

[0033] The rotating table 312 is connected to a rotary motor. Since the slider 303 will be clamped by the clamping block 308, the rotary motor can drive the rotating table 312 to rotate so that the cutting head 301 on one side rotates around the cutting head 301 on the other side. In other embodiments, the cutting head 301 can also be driven to rotate by the active contraction and swinging of the rocking arm 310.

[0034] A clamping block 308 is provided in the middle of the support table 307, which is opposite to the clamping plate 306. The clamping block 308 is provided with an inclined surface on the side opposite to the running direction of the cutting line. When the clamping plate 306 moves with the slider 303, it will interact with the clamping block 308 to clamp the slider 303. The length of the clamping block 308 is greater than L2, which increases the cutting stability of the cutting head 301. The clamping block 308 is composed of multiple small blocks, which are fixed to the support table 307 by fastening screws. The length of the support table 307 is greater than three times L2. The distance between the clamping block 308 on the side opposite to the running direction of the cutting line and the starting point of the slider 303 is greater than L2.

[0035] When cutting the first board or when the interval is long, the cutting head 301 starts to move from the starting point. After moving for t time, the cutting head 301 rotates so that the cutting head 301 on the other side returns to the starting point. The cutting head 301 as a whole is in a standby state in the form of a return. In order to enable the cutting head 301 to find a better starting position for cutting, a support 314 is provided on the support table 307. The distance L3 between 314 and the starting point of the slider 303 is N(L1+x), where N is a positive integer. When the first mineral wool board 4 reaches the position of the cutting head 301, it is triggered, and the cutting head 301 stops returning after returning N times.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
