Description

Technical Field

[0001] This invention relates to aluminum profile cutting technology, specifically to a scratch-resistant fully automatic aluminum profile cutting device. Background Technology

[0002] Aluminum profiles, with their lightweight, high strength, and corrosion resistance, are widely used in many fields such as architectural decoration, industrial equipment, doors, windows, and curtain walls. Cutting to length is a fundamental process in the deep processing of aluminum profiles. As processing demands continue to increase, the industry is placing higher requirements on the automation level of aluminum profile cutting, the appearance quality of finished products, and the stability of equipment operation.

[0003] Existing aluminum profile cutting equipment still has shortcomings in practical applications: aluminum chips generated during the cutting process are prone to splashing and scattering, and some aluminum chips will adhere to the surface of the aluminum profile or remain on the conveyor table. When the profile moves with the conveyor, they are squeezed and rubbed, which can easily form scratches, indentations and other appearance defects on the surface of the profile. Conventional protective structures can only achieve large-scale chip blocking. The sealing of the feed port where the profile passes is poor, and chips can easily escape from the gaps. Moreover, the profile and the feed port components are mostly in hard metal contact, which can also easily cause contact scratches, making it difficult to guarantee the processing quality of the profile surface. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic cutting device for scratch-resistant aluminum profiles to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic cutting device for scratch-resistant aluminum profiles, including a cutting table, a controller, and a quantitative feeding conveying unit and a discharge roller conveyor set at both ends of the cutting table. A cutting unit is provided on the cutting table, and the cutting unit includes a cutting groove opened on the surface of the cutting table and an internal working cavity. A cutting saw blade is installed inside the working cavity, and the top of the cutting saw blade passes through the cutting groove and extends to the top of the cutting table. The cutting table is equipped with an anti-scratching mechanism, which includes an anti-diffusion unit and a cleaning unit. The anti-spreading unit includes a splash guard fixedly installed on the top of the cutting table. The splash guard is installed on the outside of the cutting groove. Both the front and rear ends of the splash guard have material feeding ports. The interior of the splash guard is slidably connected to a mounting frame in the vertical direction. The mounting frame has a slot with the same size as the material feeding port. Both sides of the mounting frame are equipped with baffles corresponding to the slots. The baffles are equipped with fitting slots that are compatible with aluminum profiles. The inner wall of the fitting slots is equipped with hard rubber strips. The top of the splash guard is equipped with an adjusting electric rod. The bottom end of the telescopic end of the adjusting electric rod is fixedly connected to the mounting frame. The cleaning unit includes air boxes installed on the upper and lower sides of the discharge end of the splash guard. Each air box has a long strip-shaped air groove on its facing side surface, and a high-pressure air pipe is fixedly connected to the end of the air box.

[0006] Furthermore, the outline shape of the baffle corresponds to the feed port, and the overall size of the baffle is larger than the feed port.

[0007] Furthermore, the length of the air trough is greater than that of the material inlet, and the ends of the two high-pressure air pipes are fixedly connected to the same air guide pipe, which is connected to an external air source.

[0008] Furthermore, the quantitative feeding and conveying unit includes a feeding roller conveyor set at the feeding end of the cutting table. The feeding roller conveyor has an installation slot at one end near the cutting table. A first linear guide rail is installed at the bottom of the installation slot. A movable seat is slidably installed on the first linear guide rail. A feeding screw is installed on the first linear guide rail. The feeding screw is driven by a feeding motor. The movable seat is threadedly connected to the feeding screw. An electric gripper is set on the top of the movable seat.

[0009] Furthermore, the cutting unit also includes a second linear guide rail installed at the bottom of the inner wall of the working chamber, a cutting seat slidably mounted on the second linear guide rail, the cutting saw blade mounted on the cutting seat, a cutting screw mounted on the second linear guide rail, the cutting screw being driven by a cutting motor, and the cutting seat being threadedly connected to the cutting screw.

[0010] Furthermore, the cutting table is provided with an anti-accumulation mechanism, which includes several material leakage grooves symmetrically opened on both sides of the cutting groove. The cutting table is symmetrically provided with material discharge chute on both sides of the working chamber. The bottom end of the material discharge chute penetrates the cutting table. The working chamber is equipped with guide plates symmetrically distributed on both sides of the cutting groove. The bottom ends of the two guide plates are inclined in a direction away from each other. The cutting table is provided with a connecting groove connecting the bottom end of the guide plate and the material discharge chute.

[0011] Furthermore, the position, shape, and size of the guide ramp are all adapted to the material discharge trough.

[0014] Compared with the prior art, the fully automatic anti-scratch aluminum profile cutting device provided by the present invention has the following beneficial effects: This fully automatic anti-scratch aluminum profile cutting device uses a hard rubber strip in the baffle adapter groove to make flexible contact with the aluminum profile surface, replacing direct contact with the metal surface and eliminating the risk of hard scratches at the source of contact. Furthermore, the splash guard, baffle, and air boxes arranged above and below the discharge end of the splash guard can effectively form a closed cutting environment, preventing debris from splashing onto the conveying structure and adhering to the aluminum profile surface. This effectively avoids surface scratches caused by compression during subsequent movement of the aluminum profile.

[0015] This scratch-resistant, fully automatic aluminum profile cutting device features an anti-accumulation mechanism on the cutting table, allowing the debris generated during the cutting process to fall directly from the material discharge trough and be collected, preventing it from sticking to the surface of the cutting table and thus reducing the risk of scratching the surface of the aluminum profile during its movement.

[0016] This fully automatic anti-scratch aluminum profile cutting device features detachable baffles, allowing for the installation of different baffle sizes to accommodate different aluminum profile specifications during subsequent processing, thus improving the adaptability of cutting debris prevention.

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. Example

[0021] Please see Figures 1-6 An automatic cutting device for scratch-resistant aluminum profiles includes a cutting table 1, a controller, and a quantitative feeding conveying unit 11 and a discharge roller conveyor 12 disposed at both ends of the cutting table 1. The conveying surface of the discharge roller conveyor 12 is flush with the top surface of the cutting table 1 and is used to support and convey the cut aluminum profiles forward. A cutting unit is disposed on the cutting table 1. The controller is electrically connected to the electrical components of the quantitative feeding conveying unit 11, the discharge roller conveyor 12, the cutting unit, and the scratch-resistant mechanism, and is used to coordinate and control each process to run automatically according to the set logic.

[0022] In this embodiment, the cutting unit includes a cutting groove 2 formed on the surface of the cutting table 1 and an internal working cavity. The cutting unit also includes a second linear guide rail 22 installed at the bottom of the inner wall of the working cavity. A cutting seat 23 is slidably installed on the second linear guide rail 22. A cutting screw 24 is installed on the second linear guide rail 22. The cutting screw 24 is driven by a cutting motor. The cutting seat 23 is threadedly connected to the cutting screw 24. A cutting saw blade 21 is installed on the cutting seat 23. The top of the cutting saw blade 21 passes through the cutting groove 2 and extends above the cutting table 1 for performing cutting operations on aluminum profiles. In this embodiment, the cutting table 1 is equipped with an anti-scratching mechanism, which includes an anti-diffusion unit and a cleaning unit. The anti-scratching mechanism avoids aluminum chips from scratching the surface of the profile by combining physical chip blocking and sealing with high-pressure airflow chip removal.

[0023] The anti-spreading unit includes a splash guard 3 fixedly installed on the top of the cutting table 1. The splash guard 3 is installed on the outside of the cutting groove 2 to form a semi-enclosed cutting operation space. Both the front and rear ends of the splash guard 3 are provided with material outlets 31. The aluminum profile to be cut enters the cutting area through the material inlet 31 and is sent out through the material outlet 31.

[0024] The interior of the splash guard 3 is slidably connected to a mounting bracket 32 ​​along the vertical direction. The mounting bracket 32 ​​has a slot with the same position and size as the material feed port 31 for the aluminum profile to pass through. Both sides of the mounting bracket 32 ​​are equipped with baffles 33 corresponding to the slots. The outline shape of the baffles 33 corresponds to the material feed port 31, and the overall size of the baffles 33 is larger than that of the material feed port 31. It can completely block the edge gap of the material feed port 31 from the inside, improving the chip blocking and sealing effect.

[0025] The baffle 33 is equipped with an adapter groove 34 that is compatible with the aluminum profile. The inner wall of the adapter groove 34 is equipped with a hard rubber strip 36. The hard rubber strip 36 flexibly contacts the surface of the aluminum profile through which it passes. This can not only seal the gap between the feed port 31 and the profile and prevent aluminum chips from splashing outward, but also prevent metal parts from directly scratching the surface of the profile, thus eliminating the risk of scratching from the source of contact.

[0026] The top of the splash guard 3 is equipped with an adjustable electric rod 35. The telescopic end of the adjustable electric rod 35 extends vertically downward, and the bottom end of the telescopic end is fixedly connected to the top of the mounting frame 32. By adjusting the telescopic movement of the electric rod 35, the mounting frame 32 can be driven to rise and fall in the vertical direction, thereby adjusting the height position of the adapter groove 34 to adapt to the processing of aluminum profiles with different cross-sectional heights.

[0027] Furthermore, the inner wall of the splash guard 3 is equipped with right-angle guide bars 7 corresponding to the four corners of the mounting frame 32. The mounting frame 32 is slidably connected to the inner wall of the right-angle surface of the right-angle guide bars 7, providing precise guidance for the lifting and lowering movement of the mounting frame 32, avoiding operational deviation, and ensuring the smoothness of lifting and lowering.

[0028] Furthermore, bolt holes 6 are provided on both sides of the baffle 33, and threaded grooves 61 that are compatible with the bolt holes 6 are provided on the mounting bracket 32. Locking bolts 62 are threadedly connected in the threaded grooves 61, and the locking bolts 62 are threadedly connected in the threaded grooves 61 after passing through the bolt holes 6, so as to realize the detachable and fixed connection between the baffle 33 and the mounting bracket 32, which makes it easy to replace the baffle 33 and the hard rubber strip 36 of the corresponding size according to different profile cross-section specifications.

[0029] The top of the splash guard 3 has an operating port 63, and a cover plate 64 is provided at the operating port 63. The operating port 63 is located directly above the locking bolt 62. When the baffle 33 needs to be replaced, the cover plate 64 can be opened and tools can be inserted through the operating port 63 to remove or install the locking bolt 62 without disassembling the entire splash guard 3. The maintenance operation is convenient and efficient.

[0030] The cleaning unit includes air boxes 4 installed on the upper and lower sides of the discharge end of the splash guard 3. The two air boxes 4 are symmetrically arranged vertically, and each of the two air boxes 4 has a long strip-shaped air groove 41 on its facing side surface. The length of the air groove 41 is greater than that of the material inlet 31, so that the air blowing range completely covers the area through which the profile passes, without any dead corners for chip removal. A high-pressure air pipe 42 is fixedly connected to the end of the air box 4, and the ends of the two high-pressure air pipes 42 are fixedly connected to the same air guide pipe 43, which is connected to an external air source. The high-pressure airflow enters the interior of the air box 4 through the air guide pipe 43 and the high-pressure air pipe 42, and is finally sprayed evenly onto the surface of the aluminum profile through the air groove 41. The airflow on the upper and lower sides works synchronously to completely blow away the aluminum chips attached to the upper and lower surfaces of the aluminum profile after cutting, preventing the aluminum chips from being squeezed and scratched on the surface when the profile is conveyed to subsequent work stations.

[0031] In this embodiment, the quantitative feeding and conveying unit 11 includes a feeding roller conveyor 111 disposed at the feeding end of the cutting table 1. The conveying surface of the feeding roller conveyor 111 is flush with the top surface of the cutting table 1 and is used to support and convey the aluminum profile to be cut forward.

[0032] The feeding roller conveyor 111 has an installation slot near the cutting table 1. A first linear guide rail 112 is installed at the bottom of the installation slot, extending along the conveying direction of the aluminum profile. A movable seat 113 is slidably installed on the first linear guide rail 112, and a feeding screw 114 is installed on the first linear guide rail 112. The feeding screw 114 is arranged along the length of the first linear guide rail 112 and is driven by a feeding motor. The movable seat 113 is threadedly connected to the feeding screw 114, and an electric gripper 115 is installed on the top of the movable seat 113. The feeding motor is electrically connected to a controller. The feeding motor drives the feeding screw 114 to rotate, which in turn moves the movable seat 113 and the electric gripper 115 along the conveying direction. The controller can precisely control the movement stroke by controlling the number of rotations of the motor, thereby achieving high-precision quantitative feeding and ensuring the consistency of the finished product cutting dimensions.

[0033] In this embodiment, the cutting table 1 is equipped with an anti-accumulation mechanism, which includes several material leakage channels 5 symmetrically opened on both sides of the cutting groove 2. The cutting table 1 also has symmetrically opened material discharge chute 51 located on both sides of the working chamber. The bottom end of the material discharge chute 51 penetrates the cutting table 1. Inside the working chamber, guide inclined plates 52 symmetrically distributed on both sides of the cutting groove 2 are installed. The position, shape, and size of the guide inclined plates 52 are adapted to the material leakage channels 5. The bottom ends of the two guide inclined plates 52 are inclined in a direction away from each other, forming a downward guiding slope. The cutting table 1 has a connecting groove 53 connecting the bottom ends of the guide inclined plates 52 and the material discharge chute 51. Aluminum chips generated during the cutting process fall into the working chamber through the material leakage channels 5, then onto the guide inclined plates 52, slide down the inclined surface into the connecting groove 53, and are finally automatically discharged to the outside of the cutting table 1 through the material discharge chute 51. This effectively prevents aluminum chips from accumulating on the surface of the cutting table 1, the working chamber, and the guide rails, ensuring the stability of equipment operation and reducing the frequency of manual chip cleaning and maintenance.

[0034] In use, the aluminum profile to be cut is conveyed forward by the feeding roller conveyor 111, the electric gripper 115 clamps the end of the profile, and the feeding motor drives the moving seat 113 to move according to the set stroke through the feeding screw 114, accurately conveying the profile to the cutting position; then the electric rod 35 is adjusted to drive the mounting frame 32 to descend, so that the hard rubber strip 36 in the adapter groove 34 fits against the surface of the aluminum profile, closes the gap of the feed port 31, and restricts the movement of the aluminum profile.

[0035] The cutting motor drives the cutting screw 24 to rotate, which in turn drives the cutting seat 23 and the cutting saw blade 21 to feed smoothly and cut the aluminum profile. During the cutting process, the splash guard 3 and the baffle 33 prevent aluminum chips from splashing. Most of the aluminum chips fall to the guide inclined plate 52 and are automatically discharged from the equipment through the feeding chute 51.

[0036] After cutting, the cutting saw blade 21 retracts, and at the same time, the high-pressure airflow from the upper and lower air boxes 4 blows away all the aluminum chips remaining on the surface of the profile. Then, the high-pressure airflow stops blowing, and the adjusting electric rod 35 drives the mounting bracket 32 ​​to move upward, so that the baffle 33 separates from the aluminum profile. After that, the aluminum profile to be cut continues to be conveyed forward, and the cut aluminum profile is completely pushed onto the unloading roller conveyor 12, so that the unloading roller conveyor 12 can convey the cut aluminum profile to the next process.

[0037] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
