Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing building wall materials, and more specifically, to a milling machine for producing a new type of wall material. Background Art

[0002] The milling machine is mainly used for the secondary processing technology after the automatic lathe. It can realize processes such as milling flat grooves through modification, and can also be equipped with processes such as drilling, tapping, and chamfering. It is also called a compound machine or a special-purpose machine tool. It can also be used for milling grooves of various non-standard metal materials such as various metal materials and plastic materials. It is suitable for milling grooves and milling flat surfaces at both ends of various shaft core parts, such as D-shaped surfaces, parallel surfaces, grooves, parallel grooves, one-word grooves, cross grooves, etc. For building wall materials, the milling machine can also process stones.

[0003] The main function of the milling machine for producing wall materials is to precisely process the mortise and tenon grooves of the wall materials, enhance the structural stability, improve the wall surface aesthetics, and realize efficient and automated operation in mass production. The milling machine can precisely process the required mortise and tenon groove dimensions of the wall materials to ensure that the spliced walls are tightly joined. This precision not only enhances the structural stability of the wall but also significantly improves the overall aesthetics of the wall surface. Compared with traditional manual milling or simple mechanical processing, the milling machine adopts an automated operation mode, greatly improving the production efficiency. The operator only needs to input parameters on the touch screen interface, and the equipment can automatically complete processes such as positioning, milling, and tool withdrawal. However, when chipping occurs during the stone milling process, the staff needs to quickly handle it; In the prior art, due to the important influence of physical properties such as the hardness and brittleness of stones on the processing process, when the stone hardness is high, it will accelerate the wear of the tool. When there are differences in tool wear and tool cutting parameters, chipping of the stone will occur during the milling process. After chipping of the stone, the flying small stones will pose a safety hazard. At the same time, the equipment will also be damaged due to the impact of the stones on the equipment. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a milling machine for producing a new type of wall material.

[0005] To solve the above problems, the present invention adopts the following technical solutions, which can realize that the movable frame will adjust its position correspondingly when the milling part replaces the milling position of the stone, so that the movable frame, the main baffle and the side baffle always cover the milling position of the stone, avoiding the splashing of stones caused by chipping during the milling process.

[0006] A milling machine for producing a new type of wall material includes a machine body and electric guide rails arranged on the front and rear sides of the machine body. A hoisting bracket is slidably sleeved outside the electric guide rail, a milling part is slidably sleeved outside the hoisting bracket, and a shielding component is arranged outside the milling part; The shielding component includes a movable frame slidably sleeved outside the milling groove component. A moving groove is formed through the upper end of the movable frame, and the milling groove component is slidably connected inside the moving groove. The lower side of the movable frame is provided with first limiting grooves arranged in an annular array. A limiting plate is slidably connected inside the first limiting grooves. Main baffles are fixedly connected to the lower sides of the limiting plates on the left and right sides, and side baffles are fixedly connected to the lower sides of the limiting plates on the front and back sides. The main baffles and the side baffles are both slidably connected inside the first limiting grooves.

[0007] Further, the shape of the first limiting groove is adapted to the shape of the limiting plate. First embedding grooves are formed on the front and back sides of the upper end of the machine body, and the lower side of the side baffle is slidably in contact with the inside of the first embedding groove.

[0008] Further, an observation component is provided inside the movable frame. The observation component includes first observation windows arranged on the left and right sides of the movable frame.

[0009] Further, a second observation window is arranged on the inner surface of the main baffle. After the second observation window moves upward, its position corresponds to that of the first observation window. Rollers are rotatably connected to the lower sides of the main baffle and the side baffles, and the rollers are in rolling contact with the upper end of the machine body.

[0010] Further, trapezoidal blocks are fixedly connected to the front and back sides of the left part of the upper end of the machine body. The inclined surfaces of the trapezoidal blocks face the main baffle, and the rollers are in rolling contact and extrusion with the inclined surfaces and the upper sides of the trapezoidal blocks after rolling.

[0011] Further, a collection component is provided inside and outside the machine body. The collection component includes connecting plates fixedly connected to the lower end of the movable frame and arranged in a rectangular array.

[0012] Further, second embedding grooves are formed on the front and back sides of the lower end of the inner surface of the machine body. A collection box is slidably connected inside the second embedding grooves. Second limiting grooves are formed on the left and right sides inside the collection box, and the connecting plates are slidably connected inside the second limiting grooves. Storage grooves are formed on the opposite surfaces of the collection boxes corresponding to each other front and back.

[0013] Further, the connecting plates are L-shaped. The shape of the second embedding groove is adapted to the shape of the collection box, and the lower side of the entrance of the storage groove is inclined.

[0014] Further, a detection component is provided inside and outside the collection box. The detection component includes an installation groove formed on one side of the storage groove away from the movable frame.

[0015] Further, an extrusion plate is slidably connected inside the installation groove. A detection bracket is fixedly connected to the side of the extrusion plate away from the storage groove. The detection bracket penetrates through the side of the collection frame close to the movable frame. Pressure sensors are arranged in a linear array inside the installation groove, and the pressure sensors are in pressing contact with the extrusion plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In the present invention, the movable frame and the milling groove member move synchronously, and always wrap the milling groove member and the area of stone processing. Since the movable frame will adjust its position correspondingly when the milling groove position of the stone is changed by the milling groove member, the movable frame, the main baffle and the side baffle always cover the position of stone milling groove, avoiding the stone flying due to chipping during the milling process, not only improving the safety during the working process of the milling groove member, but also preventing other structures above the machine body from being damaged by the flying stones.

[0017] (2) In the present invention, the first observation window retracts into the limit groove and corresponds to the second observation window. Since the inside of the movable frame can be observed in real time through the first observation window and the second observation window when the movable frame covers the stone material, when the movable frame moves to the position of the trapezoidal block, the main baffle will be gradually lifted by the trapezoidal block, resulting in the complete exposure of the inside of the movable frame, which is convenient for maintaining and replacing the structures inside the movable frame.

[0018] (3) In the present invention, the collection frame moves with the movable frame, and the collection frame will collect the coolant and stones generated during the stone milling process through the storage groove. Since the collection frame is always synchronized with the milling groove member when the milling groove member processes the stone material, it is convenient for the storage groove to collect the waste materials and coolant generated during the stone milling process in time. At the same time, the stones splashed due to chipping will also be collected and enter the storage groove through the flow of the coolant. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 8 , a grooving machine for producing new wall materials, including a machine body 1 and electric guide rails 11 arranged on the front and rear sides of the machine body 1. A hoisting bracket 12 is slidably sleeved on the outside of the electric guide rail 11, and a grooving member 13 is slidably sleeved on the outside of the hoisting bracket 12. A shielding member 2 is arranged on the outside of the grooving member 13; The shielding member 2 includes a movable frame 21 slidably sleeved on the outside of the grooving member 13. A moving groove 22 is opened through the upper end of the movable frame 21. The grooving member 13 is slidably connected to the inside of the moving groove 22. The lower side of the movable frame 21 is provided with first limiting grooves 23 arranged in a circular array. A limiting plate 24 is slidably connected to the inside of the first limiting groove 23. Main baffles 25 are fixedly connected to the lower sides of the limiting plates 24 on the left and right sides, and side baffles 26 are fixedly connected to the lower sides of the limiting plates 24 on the front and rear sides. The main baffles 25 and the side baffles 26 are both slidably connected to the first limiting groove 23.

[0023] The shape of the first limiting groove 23 is adapted to the shape of the limiting plate 24. First embedding grooves 27 are opened on the front and rear sides of the upper end of the machine body 1. The lower side of the side baffle 26 is slidably in contact with the inside of the first embedding groove 27.

[0024] By adopting the above technical solution, after the stone is placed inside the machine body 1, the staff can start the machine body 1 to control the electric guide rail 11, so that the hoisting bracket 12 drives the milling groove member 13 to move left and right above the machine body 1 and the stone. At the same time, the staff can also control the milling groove member 13 to move back and forth outside the hoisting bracket 12. The movable frame 21 is sleeved outside the milling groove member 13 through the moving groove 22. As the milling groove member 13 moves back and forth, the milling groove member 13 slides back and forth inside the moving groove 22. When the milling groove member 13 moves to the position where the stone needs to be milled, the hoisting bracket 12 drives the milling groove member 13 and the movable frame 21 to move downward. Then, the milling groove member 13 is started. After the milling groove member 13 contacts the stone, the stone is milled. Since the main baffle 25 and the side baffle 26 that slide inside the first limit groove 23 through the limit plate 24 are both in contact with the upper side of the machine body 1 and can slide above the machine body 1, during the downward movement of the movable frame 21, the limit plate 24, the main baffle 25 and the side baffle 26 slide relative to the inside of the first limit groove 23. At this time, the movable frame 21 will cooperate with the main baffle 25 and the side baffle 26 to always wrap outside the milling groove member 13, and the area of the stone being milled will also be covered by the movable frame 21, the main baffle 25 and the side baffle 26. As the milling groove member 13 adjusts the milling position, the movable frame 21 will also move following the milling groove member 13. Since the movable frame 21 will correspondingly adjust its position when the milling groove member 13 changes the milling position of the stone, the movable frame 21, the main baffle 25 and the side baffle 26 always cover the position where the stone is milled, avoiding the stone from splashing due to chipping during the milling process, not only improving the safety during the working process of the milling groove member 13, but also preventing other structures above the machine body 1 from being damaged by the splashing stones.

[0025] As Figures 2 to 5 shown, an observation assembly 28 is provided inside the movable frame 21. The observation assembly 28 includes first observation windows 281 provided on the left and right sides of the movable frame 21.

[0026] A second observation window 282 is provided on the inner surface of the main baffle 25. After the second observation window 282 moves upward, its position corresponds to that of the first observation window 281. Roller wheels 284 are rotatably connected to the lower sides of the main baffle 25 and the side baffle 26, and the roller wheels 284 are in rolling contact with the upper end of the machine body 1.

[0027] Trapezoidal blocks 283 are fixedly connected to the front and rear sides of the left part of the upper end of the machine body 1. The inclined surfaces of the trapezoidal blocks 283 face the main baffle 25, and the roller wheels 284 are in rolling contact with the inclined surfaces and the upper sides of the trapezoidal blocks 283 after rolling.

[0028] By adopting the above technical solution, when the movable frame 21 is at a high position, the main baffle 25 and the side baffle 26 will keep contacting the upper side of the machine body 1 due to their own weights. At this time, the second observation window 282 inside the main baffle 25 will be directly exposed. At this time, the staff can observe the real-time states of the milling groove member 13 and the stone material inside the movable frame 21 through the second observation window 282. If the movable frame 21 moves downward, the movable frame 21 coincides with the main baffle 25 and the side baffle 26. At this time, the first observation window 281 and the second observation window 282 on the side of the movable frame 21 coincide, enabling the staff to observe the states of the milling groove member 13 and the stone material inside the movable frame 21 through the first observation window 281 and the second observation window 282. As the movable frame 21 drives the main baffle 25 and the side baffle 26 to move, the main baffle 25 and the side baffle 26 move above the machine body 1 through the rollers 284 below them. When the roller 284 below the left main baffle 25 contacts the inclined surface of the trapezoidal block 283, the main baffle 25 will be gradually lifted into the first limiting groove 23, so that the inside of the movable frame 21 can be directly exposed. Since the inside of the movable frame 21 can be observed in real time through the first observation window 281 and the second observation window 282 when the movable frame 21 covers the stone material, and when the movable frame 21 moves to the position of the trapezoidal block 283, the main baffle 25 will be gradually lifted by the trapezoidal block 283, resulting in the complete exposure of the inside of the movable frame 21, which is convenient for maintaining and replacing the structure inside the movable frame 21.

[0029] As Figures 4 to 8 shown, a collection assembly 29 is provided inside and outside the machine body 1. The collection assembly 29 includes connecting plates 291 fixedly connected to the lower end of the movable frame 21 and arranged in a rectangular array.

[0030] Second embedding grooves 293 are opened on the front and rear sides of the lower end of the inner surface of the machine body 1. A collection box 292 is slidably connected inside the second embedding grooves 293. Second limiting grooves 294 are opened on the left and right sides inside the collection box 292. The connecting plates 291 are slidably connected inside the second limiting grooves 294. Storage grooves 295 are opened on the opposite surfaces of the collection box 292 corresponding to the front and rear.

[0031] The connecting plates 291 are L-shaped. The shape of the second embedding grooves 293 is adapted to the shape of the collection box 292. The lower side at the entrance of the storage groove 295 is inclinedly opened.

[0032] By adopting the above technical solution, since the connecting plate 291 fixed below the movable frame 21 is embedded in the second limiting groove 294 inside the collecting frame 292, when the movable frame 21 moves, the connecting plate 291 will drive the collecting frame 292 to move inside the second limiting groove 294. At the same time, the opening direction of the storage groove 295 opened in the collecting frame 292 faces the stone material, so that the waste residue and coolant generated during the process of milling the groove of the stone material will flow into the storage groove 295. As the collecting frame 292 moves, the storage groove 295 will make corresponding adjustments according to the position where the groove milling member 13 works on the stone material, so that the storage groove 295 moves synchronously with the groove milling member 13. Since the groove milling member 13 processes the stone material, the position of the collecting frame 292 is always synchronized with the groove milling member 13, so that the storage groove 295 can timely collect the waste materials and coolant generated during the process of milling the groove of the stone material. At the same time, the stones splashed due to chipping will also be collected and enter the storage groove 295 through the flow of the coolant.

[0033] As Figures 6 to 8 shown, a detection component 3 is jointly provided on the inner and outer sides of the collecting frame 292. The detection component 3 includes a mounting groove 31 opened on one side of the storage groove 295 far from the movable frame 21.

[0034] A pressing plate 32 is slidably connected inside the mounting groove 31. A detection bracket 33 is fixedly connected to the side of the pressing plate 32 far from the storage groove 295. The detection bracket 33 penetrates through the side of the collecting frame 292 close to the movable frame 21. Pressure sensors 34 are arranged in a linear array inside the mounting groove 31, and the pressure sensors 34 are in pressing contact with the pressing plate 32.

[0035] By adopting the above technical solution, since the collecting frame 292 is closely attached to the front and rear sides of the stone material, and at the same time, the detection bracket 33 penetrating through the side of the collecting frame 292 will also contact the side of the stone material. When the stone material chips, the front and rear sides of the stone material will expand and squeeze the collecting frame 292 and the detection bracket 33. After being squeezed, the detection bracket 33 will push the pressing plate 32 into the mounting groove 31. However, the pressure sensors 34 inside the mounting groove 31 always support the extrusion, so that the pressing plate 32 cannot move further, resulting in a sudden increase in the pressure exerted by the pressing plate 32 on the pressure sensors 34. At this time, the pressure sensors 34 transmit information to the machine body 1, and then the machine body 1 controls the electric guide rail 11, the lifting bracket 12 and the groove milling member 13 to stop running. Since the groove milling member 13 mills the groove of the stone material, if the pressure received by the pressure sensors 34 suddenly increases, at this time, the groove milling member 13 and other structures stop running, and it provides the phenomenon that the stone material chips during the process of milling the groove for the staff. At this time, the staff can correspondingly adjust the cutting parameters of the groove milling member 13 to reduce the phenomenon of chipping of the stone material during the process of milling the groove again.

[0036] Working principle: After the stone is placed inside the machine body 1, the operator can start the machine body 1 to control the electric guide rail 11 and the lifting bracket 12 to control the moving milling groove part 13. When the milling groove part 13 moves to the position where the stone needs to be milled, start the milling groove part 13. Since both the main baffle 25 and the side baffle 26 that slide inside the first limiting groove 23 through the limiting plate 24 are in contact with the upper side of the machine body 1 and can slide above the machine body 1, during the downward movement of the movable frame 21, the limiting plate 24, the main baffle 25 and the side baffle 26 slide relative to each other inside the first limiting groove 23. At this time, the movable frame 21 will cooperate with the main baffle 25 and the side baffle 26 to always wrap around the outside of the milling groove part 13, and the area of the stone to be milled will also be covered by the movable frame 21, the main baffle 25 and the side baffle 26. At this time, the second observation window 282 inside the main baffle 25 will be directly exposed. At this time, the operator can watch the real-time state of the milling groove part 13 and the stone inside the movable frame 21 through the second observation window 282. The main baffle 25 and the side baffle 26 move above the machine body 1 through the rollers 284 below them. When the roller 284 below the left main baffle 25 contacts the inclined surface of the trapezoidal block 283, at this time the main baffle 25 will be gradually pushed up into the first limiting groove 23, and the movable frame 21 coincides with the main baffle 25 and the side baffle 26. At this time, the first observation window 281 and the second observation window 282 on the side of the movable frame 21 coincide, so that the operator can observe the state of the milling groove part 13 and the stone inside the movable frame 21 through the first observation window 281 and the second observation window 282, making the inside of the movable frame 21 directly exposed. Since the connecting plate 291 fixed below the movable frame 21 is embedded inside the second limiting groove 294 of the collecting frame 292, when the movable frame 21 moves, the connecting plate 291 will drive the collecting frame 292 to move inside the second limiting groove 294, so that the waste residue and coolant generated during the stone milling process will flow into the storage groove 295. Since the collecting frame 292 is in close contact with the front and rear sides of the stone, at the same time, the detection bracket 33 passing through the side of the collecting frame 292 will also contact the side of the stone. When the stone has a chipped edge, the front and rear sides of the stone will expand and squeeze the collecting frame 292 and the detection bracket 33. After the detection bracket 33 is squeezed, it will push the extrusion plate 32 into the installation groove 31. However, the pressure sensor 34 inside the installation groove 31 always supports the extrusion, so that the extrusion plate 32 cannot move further, resulting in a sudden increase in the pressure exerted by the extrusion plate 32 on the pressure sensor 34. At this time, the pressure sensor 34 transmits the information to the machine body 1, and then the machine body 1 controls the electric guide rail 11, the lifting bracket 12 and the milling groove part 13 to stop running.

[0037] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
