Description

Technical Field

[0001] This application relates to the field of sheet metal cutting equipment technology, specifically to a feeding device for sheet metal cutting equipment. Background Technology

[0002] In the booming development of the manufacturing industry, the sheet metal processing industry occupies an important position. Sheet metal cutting, as a key link in sheet metal processing, directly affects the efficiency and quality of the entire production process and the quality of the final product. Before cutting sheet metal, it is necessary to lift the sheet metal onto the processing platform of the sheet metal processing equipment for cutting.

[0003] Currently, when cutting sheet metal, workers usually lift the sheet metal onto the processing platform. For large and heavy sheet metal, manual manipulation is inconvenient and results in low loading efficiency, which cannot meet the needs of large-scale, high-efficiency production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a feeding device for sheet metal cutting equipment. This device eliminates the need for manual lifting of sheet metal onto the processing platform, facilitating easy loading of sheet metal onto the platform, reducing the labor intensity of workers, increasing the feeding efficiency of sheet metal, and improving the overall efficiency of sheet metal cutting. It solves the problem that currently, when cutting sheet metal, workers typically lift the sheet metal onto the processing platform, which is inconvenient for large and heavy sheet metal pieces, resulting in low feeding efficiency and failing to meet the needs of large-scale, high-efficiency production.

[0005] To achieve the goal of eliminating the need for manual lifting of sheet metal onto the processing platform, facilitating easy lifting of sheet metal onto the processing platform, reducing the labor intensity of workers, increasing the efficiency of sheet metal loading, and improving the overall efficiency of sheet metal cutting, this application provides the following technical solution: A loading device for sheet metal cutting equipment, comprising a base, a processing platform mounted on the top of the base, a cutting device mounted on the top of the processing platform, a lifting plate on one side of the processing platform, a fixing plate at the end of the lifting plate, a chain mounted on the top of the fixing plate, one end of the chain away from the fixing plate being mounted on one end of a winding rope, the middle portion of the chain being wound around a sprocket and meshing with the sprocket, the end of the winding rope away from the chain being mounted on the outer surface of the middle portion of a winding wheel, the winding wheel being located below the sprocket, the rotating shaft in the middle of the winding wheel being rotatably mounted on the top of the base via a support frame, the rotating shaft in the middle of the sprocket being rotatably mounted on the top of the base via a support frame, and a motor being connected to the winding wheel via a transmission shaft.

[0006] The above solution involves placing the sheet metal on a lower lifting plate. The motor operates, driving a winding wheel via a drive shaft. As the winding wheel rotates, it winds up a winding rope, causing the rope to pull a chain over the sprocket. This chain then passes through a fixed plate, lifting the lifting plate upwards. The lifting plate raises the sheet metal to the same height as the processing platform, allowing it to slide onto the platform. This eliminates the need for manual lifting of the sheet metal, facilitating easy transfer and reducing the workload for workers. It also improves the efficiency of sheet metal loading and the overall efficiency of sheet metal cutting.

[0007] Furthermore, each of the four corners of the lifting plate is provided with a limiting frame, the inner wall of the middle part of the limiting frame is slidably disposed on the outer surface of the middle part of the limiting rod, and the limiting rod is disposed on the top of the base.

[0008] By using the above method, the angle of the lifting plate can be limited and the stability of the lifting plate can be improved by sliding the inner wall of the middle part of the limiting frame on the outer surface of the middle part of the limiting rod.

[0009] Furthermore, multiple rotating rollers are rotatably arranged on the inner wall of the top of the lifting plate.

[0010] The above solution transforms the sliding friction between the sheet metal and the lifting plate into rolling friction, greatly reducing friction and making the process of pushing the sheet metal easier and smoother. This further reduces the labor intensity of the workers and improves the efficiency of the sheet metal sliding onto the processing platform, thereby improving the efficiency of the entire loading process.

[0011] Furthermore, both ends of the lifting plate are provided with fixing plates, and the top of the two fixing plates at both ends of the lifting plate is provided with chains. One end of the two chains is provided at one end of the two winding ropes, and the other end of the two winding ropes is provided on the middle outer surface of the two winding wheels. The two winding wheels are located at both ends of the lifting plate.

[0012] The above-mentioned scheme, which sets up chains, winding ropes and winding wheels at both ends of the lifting plate, allows for the simultaneous application of upward lifting force from both ends of the lifting plate. This makes the force on the lifting plate more even during the ascent, avoiding the problem of tilting or swaying of the lifting plate caused by uneven force on one side. It improves the stability and reliability of the lifting plate's ascent, ensuring that the sheet metal can be smoothly lifted to the height of the processing platform and guaranteeing the smooth progress of the loading process.

[0013] Furthermore, each of the two winding reels has a drive shaft at one end of its central rotating shaft. The two drive shafts are connected by a synchronous pulley and a synchronous belt. One end of one of the drive shafts is located at one end of the motor output shaft. The motor is mounted on the top of the base via a mounting bracket.

[0014] The above scheme achieves synchronous transmission between the two drive shafts via a synchronous pulley and a synchronous belt, thereby enabling the two winding reels to rotate synchronously. When the motor starts, the drive shaft drives one winding reel to rotate, and simultaneously, through the transmission of the synchronous pulley and synchronous belt, the other winding reel also rotates synchronously. This ensures that the winding speed of the winding rope is consistent between the two winding reels, keeping the tension at both ends of the lifting plate synchronized. This further improves the stability and accuracy of the lifting plate's ascent, ensuring that the sheet metal can be accurately lifted to the processing platform position, thus improving the accuracy and efficiency of material loading.

[0015] Furthermore, during the lifting preparation stage when the lifting plate is at its lowest point, the two winding ropes are perpendicular to the top of the two winding wheels, and one end of each of the two winding ropes is located at the highest point of the top of the two winding wheels.

[0016] The above scheme enables the two winding wheels to wind the two winding ropes with the same winding amplitude when they rotate synchronously in the same direction. This avoids the two winding ropes being unable to wind with the same amplitude due to the synchronous rotation of the two winding wheels and the opposite stretching of the two chains, thereby preventing the two chains from being unable to lift the two ends of the lifting plate synchronously.

[0017] Furthermore, two limiting rings are provided on both sides of the outer surface of the middle part of the winding reel, and the two limiting rings are located on both sides of the corresponding winding rope.

[0018] The above solution uses two limiting rings to restrict the winding rope, preventing it from falling off the winding wheel and thus preventing the chain from being pulled.

[0019] Furthermore, the distance between the two limiting rings on the outer surface of the middle part of the winding wheel is adapted to the diameter of the winding rope.

[0020] The above scheme limits the winding trajectory of the winding rope on the outer surface of the middle part of the winding wheel by the distance between the two corresponding limit rings, thereby fixing the winding amplitude of the winding wheel on the winding rope.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This sheet metal cutting equipment's loading device involves placing the sheet metal on a lower lifting plate. A motor operates, driving a winding wheel via a transmission shaft. As the winding wheel rotates, it winds up a winding rope, causing the rope to pull a chain over the sprocket. The chain then passes through a fixed plate, lifting the lifting plate upwards. The lifting plate raises the sheet metal to the same height as the processing platform, allowing it to slide onto the processing platform without manual lifting. This eliminates the need for manual lifting of the sheet metal, facilitating easy loading, reducing labor intensity, increasing loading efficiency, and improving the overall efficiency of sheet metal cutting.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a sheet metal cutting equipment feeding device includes a base 1, a processing platform 2 on the top of the base 1, a cutting device 3 on the top of the processing platform 2, a lifting plate 4 on one side of the processing platform 2, a fixing plate 5 at the end of the lifting plate 4, a chain 6 on the top of the fixing plate 5, one end of the chain 6 away from the fixing plate 5 being disposed at one end of a winding rope 8, the middle part of the chain 6 being wound around the top of a sprocket 7, the chain 6 being engaged with the sprocket 7, the end of the winding rope 8 away from the chain 6 being disposed on the outer surface of the middle part of a winding wheel 9, the winding wheel 9 being located below the sprocket 7, the rotating shaft in the middle of the winding wheel 9 being rotatably disposed on the top of the base 1 via a support frame, the rotating shaft in the middle of the sprocket 7 being rotatably disposed on the top of the base 1 via a support frame, and the winding wheel 9 being connected to a motor 12 via a transmission shaft 10.

[0026] Please see Figure 1 , Figure 2 and Figure 4 Limit frames 15 are provided at the four corners of both ends of the lifting plate 4. The inner wall of the middle part of the limit frame 15 is slidably disposed on the outer surface of the middle part of the limit rod 14. The limit rod 14 is disposed on the top of the base 1. By sliding the inner wall of the middle part of the limit frame 15 on the outer surface of the middle part of the limit rod 14, the angle of the lifting plate 4 when moving can be limited, thereby improving the stability of the lifting plate 4 when moving.

[0027] Please see Figure 1 , Figure 2 and Figure 3 Multiple rotating rollers 16 are rotatably arranged on the inner wall of the top of the lifting plate 4. The arrangement of the rotating rollers 16 can transform the sliding friction between the sheet metal and the lifting plate 4 into rolling friction, which greatly reduces the friction force and makes the process of pushing the sheet metal easier and smoother, further reducing the labor intensity of the workers. At the same time, it also improves the efficiency of the sheet metal sliding onto the processing platform 2, thereby improving the efficiency of the entire loading process.

[0028] Please see Figure 1 , Figure 3 and Figure 4 Both ends of the lifting plate 4 are equipped with fixing plates 5. The top of the two fixing plates 5 at both ends of the lifting plate 4 is equipped with chains 6. One end of the two chains 6 is attached to one end of the two winding ropes 8, and the other end of the two winding ropes 8 is attached to the outer surface of the middle part of the two winding wheels 9. The two winding wheels 9 are located at both ends of the lifting plate 4. The structure of chains 6, winding ropes 8 and winding wheels 9 at both ends of the lifting plate 4 can apply an upward lifting force from both ends of the lifting plate 4 at the same time, so that the lifting plate 4 is subjected to more even force during the rising process. This avoids the problem of the lifting plate 4 tilting or swaying due to uneven force on one side, improves the stability and reliability of the lifting plate 4 rising, and ensures that the sheet metal can be smoothly lifted to the height of the processing platform 2, thus ensuring the smooth progress of the loading process.

[0029] Please see Figure 1 , Figure 3 and Figure 4 Each of the two winding reels 9 has a drive shaft 10 at one end of its central rotating shaft. The two drive shafts 10 are connected by a synchronous pulley and a synchronous belt 11. One end of one drive shaft 10 is located at one end of the output shaft of the motor 12. The motor 12 is mounted on the top of the base 1 via a mounting bracket. The synchronous pulley and synchronous belt 11 enable the synchronous transmission of the two drive shafts 10, thus allowing the two winding reels 9 to rotate synchronously. When the motor 12 starts, it drives one winding reel 9 to rotate via the drive shaft 10. Simultaneously, through the transmission of the synchronous pulley and synchronous belt 11, the other winding reel 9 also rotates synchronously. This ensures that the winding speed of the winding rope 8 is consistent between the two winding reels 9, keeping the tension on both ends of the lifting plate 4 synchronized. This further improves the stability and accuracy of the lifting plate 4's ascent, ensuring that the sheet metal can be accurately lifted to the position of the processing platform 2, thus improving the accuracy and efficiency of loading.

[0030] Please see Figure 1 , Figure 3 and Figure 5 When the lifting plate 4 is at its lowest point during the lifting preparation stage, the two winding ropes 8 are perpendicular to the two winding wheels 9, and one end of each winding rope 8 is located at the highest point of the top of the two winding wheels 9. This allows the two winding wheels 9 to wind the two winding ropes 8 with the same winding amplitude when they rotate synchronously in the same direction. This avoids the two winding ropes 8 from being unable to wind with the same amplitude due to the same rotation of the two winding wheels 9 and the opposite stretching of the two chains 6, thereby preventing the two chains 6 from being unable to lift the two ends of the lifting plate 4 synchronously.

[0031] Please see Figure 1 and Figure 3 Two limiting rings 13 are provided on both sides of the outer surface of the middle part of the winding wheel 9. The two limiting rings 13 are located on both sides of the corresponding winding rope 8. The two limiting rings 13 can restrict the winding rope 8 and prevent the winding rope 8 from falling off the winding wheel 9, thus preventing the chain 6 from being pulled by the winding rope 8.

[0032] Please see Figure 1 and Figure 3 The distance between the two limiting rings 13 on the outer surface of the middle part of the take-up reel 9 is adapted to the diameter of the take-up rope 8. The distance between the two limiting rings 13 can limit the take-up trajectory of the take-up rope 8 on the outer surface of the middle part of the take-up reel 9, thereby fixing the take-up amplitude of the take-up reel 9 on the take-up rope 8.

[0033] This embodiment of a sheet metal cutting equipment feeding device involves placing the sheet metal on a lower lifting plate 4. The motor 12 operates, driving the winding wheel 9 to rotate via the transmission shaft 10. As the winding wheel 9 rotates, it winds up the winding rope 8, causing the winding rope 8 to drive the chain 6 over the sprocket 7. The chain 6 then drives the lifting plate 4 upwards via the fixing plate 5, raising the sheet metal to the same height as the processing platform 2. The sheet metal is then slid from the lifting plate 4 onto the processing platform 2. This eliminates the need for manual lifting of the sheet metal onto the processing platform 2, facilitating easy loading, reducing the labor intensity of workers, increasing sheet metal feeding efficiency, and improving the overall efficiency of sheet metal cutting.

[0034] The working principle of the above embodiment is as follows: The sheet metal to be cut is placed on the lifting plate 4 located at a lower position. The motor 12 works and drives the corresponding transmission shaft 10 to rotate. When the transmission shaft 10 rotates, it will drive another transmission shaft 10 to rotate synchronously through the synchronous pulley and the synchronous belt 11. The two transmission shafts 10 drive the two winding wheels 9 to rotate synchronously. When the two winding wheels 9 rotate, they wind the two winding ropes 8 at the same amplitude, so that the winding ropes 8 pull the chain 6. When the chain 6 is pulled, it will drive the sprocket 7 to rotate. The pulling of the chain 6 by the winding ropes 8 will cause the two chains 6 to drive the two ends of the lifting plate 4 to move upward synchronously through the two fixed plates 5, so that the lifting plate 4 lifts the sheet metal upward. When the sheet metal is lifted to the height of the processing platform 2, it is pushed to slide on the lifting plate 4, so that the sheet metal slides onto the processing platform 2 through the rotating roller 16. The cutting equipment 3 cuts the sheet metal on the processing platform 2.
