Description

Technical Field

[0001] The utility model relates to machining equipment, in particular to rock wool strip milling equipment. Background Art

[0002] In related technical solutions, sandwich panels, such as clean panels, feature uneven color-coated steel panels, with rock wool strips filling the gaps between them as the core material. The surface of the rock wool strips also needs to be contoured to fit snugly against the color-coated steel panels. During processing, the rock wool strips are fed along a work surface, above which a roller assembly compresses and drives the strips forward. A milling cutter, projecting upward from the work surface, is installed on the work surface. When the rock wool strips reach the cutter position, the cutter rotates to mill multiple grooves on the underside of the strips, facilitating their fit within the panels.

[0003] The inventors learned that in the above technical solution, the distance between the pressure roller assembly and the work surface and the height of the milling cutter protruding from the work surface are fixed values, and the milling equipment cannot adapt to the milling of rock wool strips corresponding to different thicknesses and different panel shapes. Utility Model Content

[0004] In order to make up for the deficiencies of existing rock wool milling and cutting equipment, the utility model provides a rock wool strip milling and cutting equipment.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present invention is a rock wool strip milling and cutting device, comprising a frame, a knife groove plate is fixed in the frame, a pressure roller assembly is provided above the knife groove plate, the pressure roller assembly can be lifted and lowered vertically and positioned, and a conveying space for the rock wool strip is formed between the lower end of the pressure roller assembly and the upper surface of the knife groove plate, and the pressure roller in the pressure roller assembly can rotate to drive the rock wool strip to be conveyed in the conveying space along a first horizontal direction. A milling cutter groove is provided on the knife groove plate that runs through it vertically, and a milling cutter assembly is provided below the knife groove plate. The milling cutter assembly includes a milling cutter shaft and a milling cutter fixedly mounted on the milling cutter shaft. The axis of the milling cutter shaft is horizontal and perpendicular to the first direction. The milling cutter can be lifted and lowered with the milling cutter assembly to change the height of the upper end of the milling cutter protruding above the upper surface of the knife groove plate. The beneficial effects of one or more of the above technical solutions:

[0006] In this solution, a knife groove plate is provided on the frame, and a pressure roller assembly is provided above the knife groove plate. A conveying space is formed between the pressure roller assembly and the knife groove plate, and the pressure roller assembly can be raised and lowered vertically and positioned. In this solution, the lifting and lowering of the pressure roller assembly can adapt to the feeding of rock wool strips of different thicknesses toward the knife groove plate position.

[0007] In addition, the milling cutter assembly in this solution can be raised and lowered relative to the slit plate, thereby controlling the distance between the upper end of the milling cutter and the upper surface of the slit plate. This arrangement facilitates the use of the raising and lowering of the milling cutter assembly to mill grooves of varying depths on the surface of the rock wool strips, thereby adapting to the varying heights of the concave and convex surfaces on different types of color-coated steel panels.

[0022] Specifically, the rack 2 is assembled from multiple horizontal, longitudinal, and vertical frame rods 601, secured together by welding or bolting. Specifically, the four vertical frame rods 601 at the four corners of the rack 601 form legs, the lower ends of which are connected to the base plate 1 via adjustment bolts. These adjustment bolts can be rotated to adjust the distance between the base plate 1 and the lower ends of the legs, thereby enabling the legs to support uneven surfaces and maintaining the rack 2 in a roughly horizontal position.

[0023] In this embodiment, the pressure roller assembly 6 includes a square frame 601, in which multiple pressure rollers 602 are rotatably installed. The rotation axis of the pressure roller 602 is horizontal and perpendicular to the first direction. The multiple pressure rollers 602 are connected through a transmission assembly to rotate synchronously, and at least one of the pressure rollers 602 is connected to a rotational power source.

[0024] As a specific structural form, 2-4 pressing rollers 602 are mounted side by side on the frame 601, and adjacent pressing rollers 602 are connected by a sprocket chain transmission assembly or a pulley transmission assembly. The power source here is an electric motor, pneumatic motor, hydraulic motor, etc. supported by the frame 601.

[0025] In this embodiment, the pressure roller assembly 6 is connected to the first lifting assembly 5 , and the first lifting assembly 5 drives the pressure roller assembly 6 to rise and fall. The first lifting assembly 5 is supported by the frame 2 .

[0026] Specifically, the first lifting assembly 5 includes a reduction motor 506 mounted to the upper end of the frame 2 via a mounting plate 507, and a first rotary driver 503 and a second rotary driver 505 fixed to the frame 2. A first axially vertical nut seat is rotatably mounted in the first rotary driver 503, and a second axially vertical nut seat is rotatably mounted in the second rotary driver 505. A first lead screw 502 is threadedly connected to each of the first and second nut seats. The lower end of the first lead screw 502 is rotationally connected to a first rotating seat 508 on the connecting plate 501, and the lower end of the first connecting plate 501 is fixedly connected to the frame 601 via a connecting column 603. The output shaft of the reduction motor 506 drives the first and second nut seats to rotate synchronously via a gear transmission assembly and a first linkage shaft 504.

[0027] During the rotation of the first nut seat and the second nut seat, the two first lead screws 502 rotate and rise and fall synchronously, and the rise and fall of the lead screws drives the pressure roller assembly 6 to rise and fall through the connecting plate 501 and the connecting column 603 .

[0028] In some other structural arrangements, the first lifting assembly 5 here may adopt a vertically arranged electric push rod or hydraulic cylinder, and the specific connection method thereof may be set by those skilled in the art.

[0029] In this embodiment, a blade group is provided in the middle of the milling cutter shaft 410. The blade group is a plurality of milling cutters 403 arranged on the outside of the milling cutter shaft 410. The milling cutter shaft 410 is provided with a plurality of positioning sleeves 409 detachably fixed at the positions at both ends of the blade group. The number of the positioning sleeves 409 is adjustable, and the positioning sleeves 409 can stop and position the milling cutter 403.

[0031] Specifically, the second lifting assembly 3 includes a first angle plate 301 and a second angle plate 305 arranged on either side of the frame 2 along the second direction. The first angle plate 301 and the second angle plate 305 are slidably connected to the frame 2 via vertically arranged slide rail structures, allowing the first angle plate 301 and the second angle plate 305 to slide only vertically. The bearing seat 402 of the milling cutter shaft 410 is mounted on the first and second angle plates 301 and 305.

[0032] Furthermore, two third rotary actuators 303 are disposed at the bottom of the frame 2, arranged on either side of the frame 2 along the second direction. A vertical second lead screw 306 is rotatably mounted in each third rotary actuator 303. The second lead screw 306 is rotatably connected to a third nut holder in the third rotary actuator 303. The upper end of the second lead screw 306 is rotatably connected to the first angle plate 301 or the second angle plate 305 via a second rotating holder 302. A reduction motor is also disposed at the bottom of the frame 2. This reduction motor drives the two third nut holders to rotate synchronously via a second linkage shaft 304 and a gear transmission assembly, thereby driving the two second lead screws 306 to rotate synchronously and lift and lower.

[0033] At this time, the lifting and lowering of the second lead screw 306 can drive the first angle plate 301, the second angle plate 305 and the milling cutter assembly 4 to move up and down.

[0034] In this embodiment, the storage bin 401 is provided with an air jet on one side along the first direction and an air suction port on the other side. The air jet is connected to the air supply component, and the air suction port is connected to the air extraction component.

[0035] Specifically, the air extraction assembly includes an air extraction pipeline 407 and an air extraction pump (not shown). The air extraction pipeline 407 includes a main pipe and a branch pipe. One end of the main pipe is connected to the air extraction pump, and the main pipe is connected to multiple branch pipes arranged side by side. The branch pipes are respectively connected to different air suction holes on the side of the storage bin 401.

[0036] In this embodiment, the air supply assembly includes an air nozzle 408, which is arranged in the storage bin 401. The air nozzle 408 is connected to the air supply pipe 406. The air supply pipe 406 passes through the jet port to extend to the outside of the storage bin 401. The air supply pipe 406 is connected to the high-pressure air source.

[0037] Specifically, the high-pressure gas source here is provided by an air supply pump, the outlet of the air supply pump is connected to the air supply main pipe, the air supply main pipe is connected to multiple air supply branch pipes, the ends of the air supply branch pipes pass through the jet port to enter the storage bin 401, and the ends of the air supply branch pipes are connected to the above-mentioned air nozzle 408.

[0039] Specifically, the solenoid valve 405 is controlled by a remote controller, and the solenoid valve 405 is used to control the on / off of the gas supply main pipe.

[0040] In this embodiment, the cross-sectional dimensions of the inner cavity of the storage bin 401 gradually decrease from top to bottom.

[0041] Specifically, the storage bin 401 includes a horizontally arranged bottom wall, two vertically oppositely arranged side walls, and two inclined walls that are inclined downward and oppositely arranged. Here, the side walls are parallel to the first direction.

[0042] In this embodiment, the knife groove plate 404 is detachably fixed to the frame 2. Specifically, the knife groove plate 404 is detachably fixed to the frame 2 by bolts or buckles.

[0043] The milling device of the present invention does not require manual raising of the knife groove plate 404 to adjust the milling depth. The milling cutter 403 can be raised and lowered autonomously and passively hidden in the knife groove plate 404 .

[0044] In addition, the active blowing effect using the air nozzle 408 and the high-pressure air source is good. The active intermittent blowing eliminates the saw failure caused by the accumulation of rock wool foam due to poor dust collection effect, and optimizes the working environment.

[0045] Working Principle: When using this device, first adjust the distance between the pressure roller assembly 6 and the cutter plate 404 through the first lifting assembly 5 to adapt to the thickness of the rock wool strip to be milled. Then, the second lifting assembly 3 drives the milling cutter assembly 4 to rise and fall as a whole, adjusting the height of the milling cutter 403 extending upward from the milling cutter slot to adapt to the required groove depth on the surface of the rock wool strip.

[0046] The rock wool strip is then fed in a first direction. Driven by the pressure roller assembly 6, the strip passes through the conveying space. The milling cutter 403 rotates, milling the lower portion of the rock wool strip into a shape identical to that of the milling cutter 403. The resulting rock wool dust is flung toward the dust collection port under the centrifugal force of the milling cutter 403 and drawn away by the negative pressure of the air intake. After a period of operation, the solenoid valve 405 on the air supply line 406 is energized, activating high-pressure compressed air to blow the remaining rock wool dust inside the storage bin 401 toward the dust collection port.

[0047] When there is no need to mill the rock wool strips, the milling cutter 403 will be driven down by the second lifting assembly 3, and the milling cutter 403 will be hidden under the cutter groove plate 404. When used again, the lifting assembly will raise the milling cutter 403 to its original predetermined position to maintain the consistency of rock wool milling.

However, it is easy for those skilled in the art to understand that the scope of protection of the present application is not limited to the above preferred embodiments. Without departing from the technical principles of the present application, those skilled in the art may split and combine the technical solutions in the above preferred embodiments, and may also make equivalent changes or replacements to the relevant technical features.
