[0024] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0025] This application provides a thick plate milling cutter longitudinal cutting device, which is suitable for cutting plates with a thickness of 40-50mm, and is not prone to sticking to the cutter. The cut plates are free of burrs and rough edges, and the cutting effect is good.

[0026] like Figure 1 As shown, the thick plate milling cutter longitudinal cutting equipment 100 includes: a cutting device 10 and a suction device 20 offset to the side of the cutting device 10. The cutting device 10 is used to longitudinally cut thick plates, and the suction device 20 is used to suck up and collect the debris and dust generated by the cutting device 10 during the cutting process, so that there are no debris and dust on the surface of the thick plate during the cutting process, effectively ensuring the cleanliness of the production environment.

[0027] like Figure 2 , 3 As shown, the cutting device 10 includes a frame 1, at least one pair of milling cutter cutting mechanisms 2 and a transverse mechanism 3. The at least one pair of milling cutter cutting mechanisms 2 are mounted on the frame 1 at intervals in the left and right directions. The transverse mechanism 3 is driven between the frame 1 and the at least one pair of milling cutter cutting mechanisms 2 and is used to drive the at least one pair of milling cutter cutting mechanisms 2 to move in the left and right directions respectively.

[0028] Each milling cutter cutting mechanism 2 includes a milling cutter 21 capable of moving in a vertical direction and a suction hopper 22 located below the milling cutter 21. The milling cutter 21 is configured to rotate about a central axis extending in a vertical direction to cut the product. In this embodiment, a pair of milling cutter cutting mechanisms 2 arranged opposite each other are mounted on the frame 1. The operator can move the milling cutter cutting mechanisms 2 in a left-right direction according to production requirements through the transverse mechanism 3 to adjust the distance between the pair of milling cutter cutting mechanisms 2, thereby cutting out plates of the required width.

[0029] like Figure 2 , 7As shown in Figures 8 and 9, each milling cutter cutting mechanism 2 further includes a movable frame 23 slidably mounted on the frame 1, a lifting cylinder 24 mounted on the movable frame 23, and a milling cutter motor 25 driven by the lifting cylinder 24. The movable frame 23 can move back and forth in the left-right direction. The lifting cylinder 24 is used to drive the milling cutter motor 25 to move in the up-down direction. The milling cutter motor 25 is driven by the milling cutter 21 to drive the milling cutter 21 to rotate around its axis. In this embodiment, the milling cutter is made of high-strength tool steel to extend its service life. The milling cutter motor 25 is a 16,000 rpm milling machine motor, which achieves the cutting of thick plates by rotating the milling cutter 21 at high speed. The lifting cylinder 24 drives the milling cutter motor 25 and the milling cutter 21 connected thereto to rise and fall, so that the height of the milling cutter 21 can be adjusted according to the thickness of the plate, thereby adapting to the cutting of plates of different thicknesses.

[0030] The milling cutter motor 25 is mounted on a lifting frame 27. A lifting sliding assembly 28 is connected between the lifting frame 27 and the moving frame 23. The lifting sliding assembly 28 includes a lifting guide rail 281 extending in the vertical direction and a lifting slider 282 that slides with the lifting guide rail 281. The lifting guide rail 281 is mounted on the moving frame 23, and the lifting slider 282 is mounted on the lifting frame 27. The lifting frame 27 is connected to a lifting cylinder 24. Driven by the lifting cylinder 24, the lifting frame 27 drives the milling cutter motor 25 and the milling cutter 21 to move in the vertical direction through the cooperation of the lifting slider 282 and the lifting guide rail 281.

[0031] like Figure 2 , 5 As shown, each suction hopper 22 includes an inlet 221 and an outlet 222 that are positioned vertically opposite each other. A support platform 26 is arranged at the inlet 221, and a cutting notch 261 for the milling cutter 21 to pass through is provided on the support platform 26. The outlet 222 is connected to the suction device 20. The suction device 20 applies suction force to the suction hopper 22 through the outlet 222. The debris and dust generated by the milling cutter 21 cutting the thick plate are sucked into the suction hopper 22 through the cutting notch 261 and then drawn into the suction device 20 for separation and collection, so that there are no debris and dust on the surface of the plate during the cutting process. The support platform 26 of the inlet 221 is used to support the thick plate for longitudinal cutting.

[0032] A pair of support aluminum rollers 11 are rotatably mounted on the frame 1. The pair of support aluminum rollers 11 are respectively arranged on the front and rear sides of the support platform 26 to cooperate with the support platform 26 to support the thick plate moving from front to back. Each support aluminum roller 11 extends in the left and right direction.

[0033] like Figure 2 , 3As shown, each movable frame 23 is connected to the frame 1 by a first sliding assembly 4, and each suction hopper 22 is connected to the frame 1 by a second sliding assembly 5. The first sliding assembly 4 includes a first guide rail 41 extending in the left-right direction and a first slider 42 that slides with the first guide rail 41. The first guide rail 41 is mounted on the frame 1, and the first slider 42 is mounted on the movable frame 23. The movable frame 23 can drive the corresponding milling cutter motor 25 and milling cutter 21 to move smoothly in the left-right direction through the first sliding assembly 4. The second sliding assembly 5 includes a second guide rail 51 extending in the left-right direction and a second slider 52 that slides with the second guide rail 51. The second slider 52 is mounted on the suction hopper 22, and the second guide rail 51 is mounted on the frame 1. The suction hopper 22 can move smoothly in the left-right direction through the second sliding assembly 5.

[0034] The traversing mechanism 3 includes a pair of first adjusting components 31 and a pair of second adjusting components 32. Each moving frame 23 is drivenly connected to one of the first adjusting components 31 to drive the corresponding moving frame 23 to move left and right. Each suction hopper 22 is drivenly connected to one of the second adjusting components 32 to drive the corresponding suction hopper 22 to move left and right. The first adjusting components 31 and the corresponding second adjusting components 32 are drivenly connected to drive the milling cutter 21 and the corresponding suction hopper 22 to move left and right synchronously. The suction hopper 22 cooperates with the corresponding milling cutter 21 to move left and right to receive the debris and dust splashed when the milling cutter 21 cuts thick plates.

[0035] like Figure 2 , 3 As shown in Figures 4, 6, and 7, the first adjustment assembly 31 includes a first lead screw 311 extending in the left-right direction, an adjustment handwheel 312 connected to the end of the first lead screw 311, and a first nut 313 threadedly connected to the first lead screw 311. The first nut 313 is connected to the corresponding movable frame 23. When the adjustment handwheel 312 drives the first lead screw 311 to rotate around its own axis, the first nut 313 drives the connected movable frame 23 to move back and forth along the first lead screw 311, thereby achieving the purpose of adjusting the position of the milling cutter 21 in the left-right direction.

[0036] The second adjustment assembly 32 includes a second lead screw 321 extending in the left-right direction and a second nut 322 threadedly connected to the second lead screw 321. The second lead screw 321 is drivenly connected to a corresponding first lead screw 311 to rotate synchronously with the corresponding first lead screw 311. The second nut 322 is connected to a corresponding suction hopper 22. When the first lead screw 311 rotates around its own axis, the second lead screw 321 rotates synchronously around its own axis. The second nut 322 drives the connected suction hopper 22 to move back and forth along the second lead screw 321, thereby achieving the purpose of adjusting the position of the suction hopper 22 by moving synchronously with the milling cutter 21 in the left-right direction.

[0037] A synchronization assembly 33 is connected between each first lead screw 311 and its corresponding second lead screw 321. The synchronization assembly 33 includes a drive sprocket 331 coaxially arranged with the first lead screw 311, a driven sprocket 332 coaxially arranged with the second lead screw 321, and a chain 333 that cooperates with both the drive sprocket 331 and the driven sprocket 332. The chain 333 transmits the rotation of the first lead screw 311 to the second lead screw 321, so that the first lead screw 311 and the second lead screw 321 rotate synchronously. Several transition sprockets 334 are also provided between the drive sprocket 331 and the driven sprocket 332 and are rotatably mounted on the frame 1. The transition sprockets 334 change the conveying direction of the chain 333 so that the conveying of the chain 333 does not affect the cutting on the frame 1.

[0038] like Figure 1 As shown, the suction device 20 includes a cyclone separator 6 and a suction fan 7. The suction fan 7 is connected to the outlet 222 of a pair of suction hoppers 22 and the cyclone separator 6 via a duct 8. When the suction fan 7 is working, it generates suction force within the pair of suction hoppers 22 to draw the debris and dust generated by the milling cutters 21 cutting thick plates into the cyclone separator 6. The cyclone separator 6 includes a hopper 61 for containing debris and is connected to a filter bag 9. The cyclone separator 6 separates the drawn debris and dust into a cyclone. The debris is concentrated in the hopper 61, and the dust is filtered into the filter bag 9 for separate collection.
