Description

Technical Field

[0001] This utility model relates to the field of band saws, and in particular to an automatic feeding device for band saws. Background Technology

[0002] An automatic feeding device for band saws is an auxiliary device that automatically transports materials to the band saw's processing area. This device can automatically grip, transport, and position workpieces, eliminating the need for frequent manual operation. For example, when sawing metal bars in batches, it can transport the bars to the sawing position at set intervals according to a preset program, significantly improving work efficiency. Operators only need to start the equipment and monitor its operation, reducing manpower and the labor intensity of workers. However, some automatic feeding devices may encounter problems such as unstable gripping, slippage during transport, or damage to workpieces made of special materials with high hardness, easy deformation, or smooth surfaces. For instance, when gripping smooth stainless steel pipes or cylindrical bars, the grippers may not provide sufficient friction, causing the pipe to slip during transport. Utility Model Content

[0024] Examples, such as Figures 1-2 As shown:

[0025] An automatic feeding device for a band saw includes a transmission component 100 and a support frame 200 for supporting materials. In one embodiment, the transmission component 100 is typically spaced apart from the support frame 200. For example, a support frame 200 is provided at each end of a transmission component 100, and the material spans across the two support frames 200. In another embodiment, three support frames 200 may be spaced apart, with a transmission component 100 between adjacent support frames 200, and the material spans across the three support frames 200.

[0026] In one embodiment, the support frame 200 is provided with a movable component 300 for feeding materials; the movable component 300 can lift and move, thereby enabling the material to be lifted from below and then moved to a preset position; the support frame 200 is provided with a guide ramp 210; the top of the movable component 300 is provided with a roller 310 that cooperates with the guide ramp 210; the support frame 200 is connected to the movable component 300 via a lifting cylinder 220 and drives the roller 310 to move along the guide ramp 210, thereby realizing the lifting and lowering movement of the movable component 300 to achieve the purpose of lifting the material; that is, in use, the movable component 300 is positioned below the material; one end of the lifting cylinder 220 is hinged to the bottom of the support frame 200; the telescopic rod of the lifting cylinder 220 is connected to the movable component 300; in one embodiment In this embodiment, the roller 310 can be a bearing; using a bearing as the roller 310 enables the roller 310 to have sufficient rigidity and effectively support the movement of the entire movable component 300; the movable component 300 includes a linear guide rail 330 and a limiting plate 360 ​​slidably connected thereto; the limiting plate 360 ​​is provided with a locking groove 231 for limiting the material; the limiting plate 360 ​​is driven by a motor 354 to move along the linear guide rail 330 and move the material; the movable component 300 can achieve vertical movement as a whole, and the limiting plate 360, in conjunction with the linear guide rail 330, can achieve horizontal movement. The limiting plate 360 ​​is the main component supporting the material. After the two movements are superimposed, the material can be effectively transported, realizing automatic material feeding. At the same time, the locking groove 231 can ensure the stability and reliability of the bar material during transportation.

[0027] In one embodiment, the transmission assembly 100 includes a plurality of transmission rollers arranged at the center of the support frame 200; the length direction of the support frame 200 is perpendicular to the length direction of the transmission assembly 100; the support frame 200 includes a support plate 230 for supporting materials; the support plate 230 is provided with a plurality of locking grooves 231 for limiting the materials; through the plurality of locking grooves 231 on the support plate 230, the materials can be temporarily stored, facilitating the loading of the movable assembly 300; in one embodiment, the locking grooves 231 on the support plate 230 are respectively arranged on both sides of the transmission assembly 100;

[0028] In one embodiment, two support plates 230 are spaced apart; the movable component 300 is disposed between the two support plates 230; a low-position region 240 is formed in the middle of the support plate 230, which cooperates with the transmission component 100 and is lower than the transmission component 100; by setting two support plates 230, the pressure on the support plates 230 can be reduced, ensuring the strength of the support structure, and the spaced support plates 230 have a larger support range for the material, resulting in better support stability; by setting the low-position region 240, interference with the material is avoided, ensuring that after the movable component 300 moves into place, the material can fall completely onto the transmission component 100, facilitating transmission.

[0029] In one embodiment, the support frame 200 is provided with at least two guide ramps 210 to ensure the stability of the movable component 300 during upward movement; in another embodiment, the support frame 200 is provided with three guide ramps 210.

[0030] In one embodiment, the movable component 300 includes a base 320; a linear guide rail 330 is mounted on the base 320; a slider 340 is slidably connected to the linear guide rail 330; the top of the slider 340 is connected to a limiting plate 360 ​​via a mounting plate 350; in one embodiment, multiple sliders 340 may be provided; the top of the slider 340 is fixedly connected to the mounting plate 350; the top of the mounting plate 350 is fixedly connected to the limiting plate 360; in one embodiment, the limiting plate 360 ​​is preferably mounted on the mounting plate 350 at a position relative to the slider 340, thereby ensuring that the pressure borne by the limiting plate 360 ​​can be directly transmitted to the slider 340; the side of the mounting plate 350 away from the slider 340 is fixedly mounted on a chain 351; the chain 351 is driven by a sprocket 352; a reducer 353 is provided on the base 320; the output shaft of the reducer 353 is connected to the sprocket 352; a motor 354 is connected to the reducer 353. The motor 354 rotates, which in turn drives the sprocket 352 to rotate. The rotation of the sprocket 352 drives the chain 351 to move, thereby enabling the limiting plate 360 ​​to move along the linear guide rail 330 in a straight line.

[0031] like Figure 3 The diagram shows the first state of the active component 300. At this point, the height of the limiting plate 360 ​​is lower than that of the support plate 230, and the material is in its initial state. Figure 4As shown, this is a schematic diagram of the second state of the movable component 300. At this time, the height of the limiting plate 360 ​​is higher than that of the support plate 230, and the material is lifted by the limiting plate 360. That is, the first state is followed by the second state. The process of the movable component 300 being lifted by the lifting cylinder 220 is also the process of the movable component 300 lifting the material. After the material is lifted, the motor 354 can drive the chain 351 to rotate, thereby moving the material to the transmission component 100. The cylinder further retracts, the movable component 300 falls, and the material is transported to the transmission component 100, realizing the automatic feeding of the material (bar).

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
