Description

Technical Field

[0001] This utility model relates to the technical field of large sheet metal transfer equipment, and in particular to a sheet metal processing feeding device. Background Technology

[0002] With the increasing demand for high-precision and high-efficiency metal processing in the industrial manufacturing sector, laser cutting equipment is widely used in sheet metal processing, structural component manufacturing and other fields due to its advantages such as fast cutting speed, high precision and wide material adaptability.

[0003] For large sheet materials, such as those 2-3 meters long and 1 meter wide or even larger, the primary prerequisite for laser cutting operations is the accurate and safe feeding of the raw sheet material onto the laser cutting machine's cutting platform. However, currently, the main methods for feeding large sheet materials include the following two:

[0004] On the one hand, some companies use overhead cranes (also known as overhead gantry cranes) combined with suction cups for hoisting and loading materials. Although this method can effectively reduce the intensity of manual labor, the purchase cost of overhead crane equipment is high, it occupies a large amount of factory space, and operation requires dedicated personnel. It also has high requirements for site layout and management, and is not suitable for small and medium-sized processing plants or companies with limited space.

[0005] On the other hand, some companies still rely on manual handling for material loading. This method poses significant safety hazards when dealing with heavy or large-area boards, greatly increases labor intensity and the risk of worker injury, and affects processing efficiency and cutting quality. Utility Model Content

[0006] The purpose of this invention is to solve the problems of high cost of overhead crane loading and heavy workload and low efficiency of manual loading in the existing technology, and to propose a sheet metal processing feeding device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A sheet metal processing feeding device is used to feed sheet metal to a laser cutting platform. The feeding device includes a rectangular frame and movable legs located at the four corners of the rectangular frame. At least two sets of winding components are arrayed along the length of the rectangular frame. The winding components are adjustable and fixed to the rectangular frame, and the adjustment direction is set along the length of the rectangular frame. The winding components include a pull rope that can be wound up and a suction cup located at the end of the pull rope. The feeding device includes a power mechanism that can simultaneously drive all the winding components to wind up or release.

[0009] The winding assembly includes a rotating shaft, which is placed along the width of a rectangular frame. Several winding wheels are mounted on the rotating shaft, and a pull rope is wound around each winding wheel. Second sliders are fixed to both ends of the rotating shaft.

The second slider is slidably connected to the second slide rail and the two are fixed together by locking bolts. The power mechanism is drivenly connected to the rotating shafts of all the winding assemblies.

[0010] The rotating shaft is fixedly mounted with a second sprocket. The power mechanism is a chain drive mechanism, which includes an annular chain. The chain drive mechanism has a first state and a second state. When the chain drive mechanism is in the first state, the annular chain is disengaged from the second sprocket. When the chain drive mechanism is in the second state, the annular chain is engaged with at least a portion of the second sprocket.

[0011] Two movable legs distributed along the length of the rectangular frame are each fixed with an electric telescopic cylinder. The electric telescopic cylinder is vertically arranged, and a first slider is fixedly connected to the telescopic end of the electric telescopic cylinder. Several first sprockets are rotatably connected to the first slider, and at least one of the first sprockets is driven by a rotary motor. The rotary motor is fixedly assembled with the first slider. The annular chain is connected between the multiple first sprockets. The annular chain includes an upper chain and a lower chain.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3 A sheet metal processing feeding device is used to feed sheet metal to a laser cutting platform. The feeding device includes a rectangular frame 15 and movable support legs 16 located at the four corners of the rectangular frame 15. The rectangular frame 15 has at least two sets of winding components arranged along its length. The winding components are adjustable and fixed to the rectangular frame 15, and the adjustment direction is set along the length direction of the rectangular frame 15. The winding components include a pull rope 2 that can be wound up and a suction cup 1 located at the end of the pull rope 2. The feeding device includes a power mechanism that can simultaneously drive all the winding components to wind up or release.

[0021] In use, this device uses suction cup 1 to contact the sheet material and form an adhesive, thus gripping the sheet material. Suction cup 1 is connected to a winding structure via a pull rope 2. When the power mechanism is activated, it drives the pull rope 2 to wind or release, causing suction cup 1 to rise or fall, achieving the lifting and placement of the sheet material. Multiple winding components are distributed along the length of the rectangular frame 15, and their connection to the rectangular frame 15 is adjustable. This is achieved through sliding installation and locking, allowing the spacing between the winding components to be adjusted according to the sheet material length or gripping position, thus accommodating sheets of different sizes. Movable support legs 16 support the entire rectangular frame 15 structure and can be moved as needed, allowing the feeding device to move above or to the side of the laser cutting platform to complete the feeding operation.

[0022] Compared with existing technologies, this device achieves efficient adsorption of the sheet material through suction cup 1, and completes lifting control through pull rope 2 in conjunction with the power mechanism, eliminating the heavy labor of manual handling, and avoiding the problems of high investment and difficult scheduling of traditional overhead crane equipment. The rectangular frame 15 is equipped with multiple sets of winding components along its length, each set of which can be adjusted to meet the gripping needs of various sheet material specifications, and has the advantages of strong applicability and convenient operation.

[0023] The winding assembly includes a rotating shaft 12, which is placed along the width of the rectangular frame 15. Several winding wheels 13 are mounted on the rotating shaft 12, and a pull rope 2 is wound around each winding wheel 13. Second sliders 11 are fixed to both ends of the rotating shaft 12. The rectangular frame 15 includes a long rod 9, and a second slide rail 14 is provided on the inner side of the long rod 9. The second sliders 11 are slidably connected to the second slide rail 14 and the two are fixed together by locking bolts 10. The power mechanism is connected to the rotating shafts 12 of all the winding assemblies.

[0024] The winding assembly of this device includes a rotating shaft 12, which is positioned along the width of the rectangular frame 15. Several winding wheels 13 are mounted on the rotating shaft 12, and a pull rope 2 is wound around each winding wheel 13. The free end of the pull rope 2 is connected to a suction cup for gripping the sheet material. When the power mechanism is activated, it drives the rotating shaft 12 to rotate, which in turn drives the winding wheels 13 to rotate, achieving synchronous winding or unwinding of the pull rope 2, and enabling the suction cup to perform upward or downward movements.

[0025] To accommodate the gripping needs of different sized sheets, second sliders 11 are fixedly connected to both ends of the rotating shaft 12. The second sliders 11 are slidably connected to the second slide rail 14 on the inner side of the rectangular frame 15. The user can adjust the position of the rotating shaft 12 along the second slide rail 14 according to the size requirements of the sheet. After adjustment, the second sliders 11 are fixed to the long rod 9 by locking bolts 10, thereby making the position of the entire winding assembly on the rectangular frame 15 adjustable.

[0026] The shaft 12 is fixedly mounted with a second sprocket 18. The power mechanism is a chain drive mechanism, which includes an annular chain 4. The chain drive mechanism has a first state and a second state. When the chain drive mechanism is in the first state, the annular chain 4 is disengaged from the second sprocket 18. When the chain drive mechanism is in the second state, the annular chain 4 is engaged with at least a portion of the second sprocket 18.

[0027] In this device, a second sprocket 18 is fixedly mounted on the rotating shaft 12. The rotating shaft 12 is used to drive the winding wheel to achieve the winding and unwinding of the rope. The power mechanism is a chain drive mechanism, which includes an annular chain 4. The meshing relationship between the annular chain 4 and the second sprocket 18 determines whether the rotating shaft 12 is driven.

[0028] The chain drive mechanism has a first state and a second state. In the first state, the annular chain 4 disengages from the second sprocket 18, interrupting the power transmission. The user can loosen the locking bolt and slide the second slider to adjust the specific position of the winding assembly on the rectangular frame to accommodate sheets of different widths or gripping point requirements. After adjustment and repositioning, the chain drive mechanism switches to the second state, where the annular chain 4 engages with at least part of the second sprocket 18. The power mechanism then drives the rotating shaft 12 to rotate, which in turn drives the winding wheel to unwind and rewind the rope, thus lifting or lowering the sheet.

[0029] In the first state, the chain drive mechanism disengages the ring chain 4 from the second sprocket 18, so that the rotating shaft 12 is temporarily not driven by the power mechanism, which is conducive to the operator safely and conveniently adjusting the position of the winding assembly; in the second state, the ring chain 4 engages with the second sprocket 18 to realize the synchronous driving of multiple winding assemblies, ensuring that the suction cup lifting action is consistent and the plate is subjected to uniform force.

[0030] Two movable legs 16 distributed along the length of the rectangular frame 15 are each fixed with an electric telescopic cylinder 3. The electric telescopic cylinder 3 is vertically arranged, and a first slider 7 is fixedly connected to the telescopic end of the electric telescopic cylinder 3. Several first sprockets 5 are rotatably connected to the first slider 7. At least one first sprocket 5 is driven by a rotary motor 6. The rotary motor 6 is fixedly assembled with the first slider 7. A ring chain 4 is connected between the multiple first sprockets 5. The ring chain 4 includes an upper chain and a lower chain. Multiple second sprockets 18 are located between the upper chain and the lower chain. When the chain drive mechanism is in the first state, the upper chain and the lower chain are disengaged from the second sprockets 18. When the chain drive mechanism is in the second state, one of the upper chain and the lower chain is engaged with the second sprocket 18.

[0031] On each of the two movable legs 16 distributed along the length of the rectangular frame 15, an electric telescopic cylinder 3 is fixedly installed. The electric telescopic cylinder 3 is vertically arranged, and its telescopic end is connected to a first slider 7. Several first sprockets 5 are rotatably mounted on the first slider 7, at least one of which is connected to a rotary motor 6 via a transmission. The rotary motor 6 is fixedly installed on the first slider 7. The position of the first slider 7 is controlled by the extension and retraction of the electric telescopic cylinder 3, thereby controlling the up and down movement of the annular chain 4 and realizing the switching between the first state and the second state.

[0032] Multiple first sprockets 5 are connected by an annular chain 4, which forms a closed transmission path and structurally includes an upper chain and a lower chain. The annular chain 4 runs under the drive of a rotary motor 6, causing the multiple first sprockets 5 to rotate in conjunction.

[0033] Multiple second sprockets 18 are arranged between the upper and lower chains. When the chain drive mechanism is in the first state, both the upper and lower chains are disengaged from the second sprockets 18. At this time, no power is provided to the second sprockets 18 and their corresponding shafts, which facilitates position adjustment. When the chain drive mechanism is switched to the second state, the upper or lower chain engages with the second sprockets 18. The rotary motor 6 drives the second sprockets 18 to rotate through the first sprocket 5 and the annular chain 4, thereby realizing the linkage drive of the shaft 12 and driving the winding wheel to perform the rope winding and unwinding operation.

[0034] A support plate 17 is fixed between the two first sliders 7, and the support plate 17 is supported at the bottom of the lower chain or at the top of the upper chain.

[0035] A support plate 17 is fixedly connected between the two first sliders 7, forming a transverse connection structure. The support plate 17 can be set at the bottom of the lower chain or the top of the upper chain as needed. When the support plate 17 abuts against the bottom of the lower chain, it can provide an upward supporting force to make the lower chain rise and form a stable meshing relationship with the second sprocket 18; when the support plate 17 is located at the top of the upper chain, it can press the upper chain downward to make it reliably contact the second sprocket 18.

[0036] With this structure, regardless of slight changes in chain tension or when switching the working state of the chain drive mechanism, the support plate 17 can provide support or clamping to ensure that the upper or lower chain always maintains good meshing contact with the second sprocket 18, thereby ensuring a smooth transmission process and continuous and reliable power transmission.

[0037] The movable support leg 16 is provided with a vertically arranged first slide rail 8, and the first slider 7 is slidably connected to the first slide rail 8. In actual use, when the electric telescopic cylinder drives the first slider 7 to move up and down, the first slide rail 8 provides guiding constraints to ensure that the first slider 7 maintains a straight vertical movement during the movement, preventing deviation or jamming.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
