[0002] Stamping equipment is a type of equipment widely used in the field of metal processing, which is used to stamp metal materials into metal workpieces with a set shape. For example, the fins of an oil cooler can be stamped from a metal material. In an existing technology, a material rack is placed on the ground of a factory building. The metal strip for making the fins of the oil cooler is wound into a roll and rotatably assembled on the material rack. The tensioning and driving mechanism is arranged on the ground beside the material rack, and the stamping equipment is further arranged on the ground beside the tensioning and driving mechanism. That is, the material rack, the tensioning and driving mechanism, and the stamping equipment are arranged in sequence in the plane direction on the ground of the factory building. The aluminum strip on the material rack is transported to the stamping equipment through the tensioning and driving mechanism for stamping and forming. However, in this existing technology, since the material rack and the tensioning and driving mechanism are arranged in sequence in the planar space, and a certain distance is required between the tensioning mechanism and the material rack to meet the tensioning requirement, the equipment for realizing feeding has a large floor area, is inconvenient to move and assemble, and the use cost increases.

[0003] In view of this, it is necessary to propose a new technical solution to overcome the deficiencies of the existing technology. Summary of the Utility Model

[0004] Based on this, this application provides a feeder with a compact structure, which is convenient to move and assemble, and can reduce the use cost.

[0035] Please refer to Figures 1 to 5As shown in the figure, the present application provides a feeder 100 for conveying a metal strip 20 to a forming device. The feeder 100 includes a frame 1, a material placing rack 2, a driving assembly, and a tensioning assembly. The material placing rack 2 is arranged on the frame 1 and is configured to carry the metal strip 20 wound into a coil; the driving assembly includes a driving roller connected to the frame 1, and the metal strip 20 passes through the driving roller to obtain the power of movement provided by the driving roller; the tensioning assembly includes a tensioning roller 41 connected to the frame 1, and the metal strip 20 passes through the tensioning roller 41 to be tensioned by the tensioning roller 41. Among them, both the driving roller and the tensioning roller 41 are located below the material placing rack 2, and an accommodating space is formed between the material placing rack 2 and the driving roller and the tensioning roller 41 to accommodate the metal strip 20 wound into a coil, and the metal strip 20 is sequentially conveyed to the forming device through the tensioning roller 41 and the driving roller. Among them, both the driving roller and the tensioning roller 41 are located below the material placing rack 2, which means that the driving roller and the tensioning roller 41 are lower than the material placing rack 2 in the height direction of the feeder 100, and they can be located directly below the material placing rack 2 or not directly below. Such a setting can make the metal strip 20 on the material placing rack 2 be placed above the driving roller and the tensioning roller 41, achieving the effect of reducing the floor area compared with the prior art.

[0036] The feeder 100 provided by the present application enables the metal strip 20 wound into a coil to occupy the space in the vertical direction of the feeder 100, reduces the floor area of the feeder 100, makes the structure of the feeder 100 more compact, and is convenient for movement and assembly, which can reduce costs.

[0037] Please refer to Figures 1 to 3 As shown in the figure, in this embodiment, the frame 1 includes a base 12 and columns 11 extending upward from the base 12. The base 12 is in the shape of a rectangular frame, which is horizontally placed on the ground, and a plurality of support feet 121 supporting the ground are provided on the base 12. It is easy to understand that in some embodiments, to strengthen the structural strength of the base 12, the base 12 may include a plurality of reinforcing beams, and the reinforcing beams may connect opposite sides of the rectangular frame or adjacent sides of the rectangular frame. In other embodiments, the base 12 is not limited to a rectangular frame and may be set to other shapes. The columns 11 are a pair and extend upward from opposite sides of the base 12. That is, there are two columns 11, and the lower ends of the columns 11 are fixed on opposite sides of the base 12. Both ends of the material placing rack 2, the driving roller, and the tensioning roller 41 are respectively installed on the two columns 11, and the pair of columns 11 are substantially parallel to each other to facilitate the installation of the material placing rack 2, the driving roller, the tensioning roller 41, etc. between the pair of columns 11. Please refer to Figure 5As shown, in this embodiment, the column 11 has an installation cavity 110, and the installation cavity 110 can be used to install some components of the driving assembly and the adjusting assembly, so as to reduce the exposure of the components. The frame 1 further includes a plurality of cross beams 13 and a plurality of vertical beams 14. The vertical beams 14 are used to install the lubrication assembly, and the cross beams 13 are used to connect the columns 11 and the vertical beams 14. Each component included in the feeder 100 will be introduced separately in sequence herein. The structures of the driving assembly, the adjusting assembly and the lubrication assembly will be described in detail later.

[0038] In this embodiment, the material placing frame 2 is located at the top end of the column 11. The top end of the column 11 is provided with a groove with an open upper part, and both ends of the material placing frame 2 can be directly placed in the groove through the opening, which is convenient for taking and placing the material placing frame 2 from the column 11. The material placing frame 2 is generally in the shape of a cylindrical rod. The metal strip 20 is wound into a strip coil 21 in a disc shape and sleeved on the material placing frame 2 through the central hole in the middle of the strip coil 21. The metal strip 20 can also be directly wound on the material placing frame 2 to form the strip coil 21.

[0039] Please continue to refer to Figures 1 to 3 As shown, the driving assembly includes a motor 31 and a driving roller. In this embodiment, the driving roller includes a driving roller 32 driven by the motor 31 and a driven roller 33 that cooperates with the driving roller 32 to clamp the metal strip 20. The driving roller 32 is driven by the motor 31 to rotate, and the driven roller 33 is driven to rotate passively by the driving roller 32, so as to convey the metal strip 20 passing through between the driving roller 32 and the driven roller 33 forward through the frictional force. Both the driving roller 32 and the driven roller 33 are connected to the pair of columns 11. Please refer to Figure 5 As shown, in this embodiment, the motor 31 drives the driving roller 32 to rotate through a sprocket mechanism 34. Specifically, the sprocket mechanism 34 includes a driving wheel connected to the output shaft of the motor 31, a driven wheel connected to one end of the driving roller 32, and a chain connecting the driving wheel and the driven wheel. The power of the output shaft of the motor 31 is transmitted to the driving roller 32 through the driving wheel, the chain and the driven wheel to drive the driving roller 32 to rotate. In other embodiments, the driving roller 32 can also be directly driven by the output shaft of the motor 31, or driven through a gear set or the like.

[0040] The operation of the motor 31 is controlled by the control box 8. The control box 8 is provided with a controller, a power module, etc. for controlling the operation of the feeder 100. In this embodiment, the control box 8 is fixed on the outer side of the lower end of the column 11 for easy operation and maintenance. Further, in this embodiment, the feeder 100 further includes other electrical components, such as an induction module, and the induction module is electrically connected to the controller and the power module in the control box 8. The induction module is used to detect the feeding state of the metal strip 20. Specifically, the induction module may include an electric field sensor, a processing chip, a transceiver unit, and a control switch, etc. The electric field sensor includes a plurality of induction electrodes, and the plurality of induction electrodes are installed on the frame 1 for detecting the feeding state. After the plurality of induction electrodes collect the touch signals, the signals are sequentially filtered, amplified, analog-to-digital converted, and data processed, and then the signals are transmitted to the control box 8 through the transceiver unit.

[0041] The tensioning assembly is used to tension the metal strip 20. The tensioning roller 41 included in the tensioning assembly is connected to the column 11. In this embodiment, the tensioning roller 41 is connected to the column 11 through a laterally extending connecting seat 42 to increase the lateral distance between the tensioning roller 41 and the driving roller, facilitating the metal strip 20 to pass through the tensioning roller 41 and then be threaded between the driving roller's driving roller 32 and the driven roller 33. In this embodiment, in the conveying direction of the metal strip 20, the tensioning roller 41 is located upstream of the driving roller, that is, the metal strip 20 passes through the tensioning roller 41 first and then through the driving roller. The tensioning roller 41 and the driving roller may be substantially on the same horizontal plane or may be arranged with a height difference, which does not affect the tensioning and conveying of the metal strip 20.

[0042] Please refer to Figures 1 to 4 As shown, the material placing frame 2, the tensioning roller 41, and the driving roller are all connected to the pair of columns 11, and their assembly and movement are convenient. There is a distance between the tensioning roller 41 and the driving roller and the material placing frame 2, and this distance is not less than the radius of the strip coil 21 formed by winding the metal strip 20, that is, this distance enables the strip coil 21 to rotate freely without being affected by the tensioning roller 41 and the driving roller. The space formed by this distance in the up and down directions is the accommodation space. Such a setting makes full use of the space of the feeder 100 in height, thereby reducing the occupation of horizontal space, that is, reducing the floor area. At the same time, it also makes the structure of the feeder 100 more compact, facilitating assembly and mobile transportation.

[0043] Please refer to Figure 5As shown, in this embodiment, the feeder 100 further includes an adjusting assembly capable of adjusting the distance between the driving roller 32 and the driven roller 33. By adjusting the distance between the driving roller 32 and the driven roller 33 through the adjusting assembly, metal strips 20 of different thicknesses can be accommodated. In this embodiment, the adjusting assembly is installed on the column 11. The adjusting assembly includes an operating handle 61 located outside the installation cavity 110 of the column 11, and a transmission mechanism assembled in the installation cavity 110. The transmission mechanism is connected between the operating handle 61 and the driven roller 33. The operating handle 61 of the adjusting assembly is located outside the installation cavity 110, which is convenient for the operator to operate. By installing the transmission mechanism of the adjusting assembly in the installation cavity 110, the exposure of transmission components is avoided, and the risk of injury to the user caused by transmission components can be reduced. In this embodiment, the transmission mechanism includes a driving wheel connected to the operating handle 61, a first slider 62 driven by the driving wheel to move, a second slider 64 connected to one end of the driven roller 33, and a connecting rod 63 connecting the first slider 62 and the second slider 64. Both ends of the driven roller 33 are installed in the installation holes opened on the column 11. The installation holes are set to be elliptical, runway-shaped and other elongated shapes to allow the driven roller 33 to move within a certain range. By rotating the operating handle 61, the first slider 62 is driven to slide up or down. The first slider 62 drives the second slider 64 to slide up or down through the connecting rod 63. Since the second slider 64 is fixed to the end of the driven roller 33, the driven roller 33 is driven to move up or down to adjust the distance between the driving roller 32 and the driven roller 33. The specific structure of the adjusting assembly is not limited to the above embodiment. In other embodiments, the adjusting assembly can also adopt a cam mechanism, a lead screw, etc. to realize the movement of the driven roller 33. Moreover, in other embodiments, the adjusting assembly can also be driven by a motor.

[0044] Please refer to Figure 2 and Figure 3 As shown, the feeder 100 includes a lubricating assembly connected to the frame 1 for lubricating the metal strip 20. In this embodiment, in the conveying direction of the metal strip 20, the lubricating assembly is located downstream of the driving roller. The lubricating assembly includes an oil dripping member 51 for dripping lubricating oil onto the metal strip 20, and an oil tank located below the oil dripping member 51 to receive the dripping lubricating oil. The metal strip 20 passes between the oil dripping member 51 and the oil tank. In one embodiment, the lubricating assembly includes two oil receiving tanks. One oil receiving tank, such as Figure 2 the first oil receiving tank 52 shown in Figure 2The second oil receiving groove 53 shown in the figure is arranged directly below the lowest point formed by the bending of the metal strip 20. In this way, the first oil receiving groove 52 can receive the excess lubricating oil directly dripped by the oil dripping member 51, and the second oil receiving groove 53 can receive the lubricating oil flowing along the surface of the metal strip 20 and finally dripping from the lowest point of the metal strip 20. Arranging the oil receiving groove to receive the lubricating oil can keep the environment clean and enable the received lubricating oil to be recycled. The metal strip 20 lubricated by the lubricating assembly is then conveyed to the forming device for forming. In one embodiment, the feeder 100 is used to convey the metal strip 20 to the fin stamping forming device to stamp and form the oil cooler fins. The metal strip 20 is made of aluminum and is stamped into aluminum oil cooler fins. Of course, in other embodiments, the forming device can also be a device for rolling or other metal forming methods, and the metal strip 20 can also be other metal materials such as iron and copper.

[0045] During use, the strip coil 21 is mounted on the frame 1 through the material placing frame 2. The metal strip 20 on the strip coil 21 is led out downward from the side close to the tension roller 41, and after being tensioned around the tension roller 41 for half a turn, it passes through between the driving roller 32 and the driven roller 33 of the driving assembly, and then after passing through the lubricating assembly, it is conveyed to the forming device.

[0046] From the description of the above specific embodiments, it can be seen that for the feeder 100 provided in the present application, the driving roller and the tension roller 41 included therein are located below the material placing frame 2. A receiving space is formed between the material placing frame 2 and the driving roller and the tension roller 41 to receive the metal strip 20 wound into a coil. The metal strip 20 is sequentially conveyed to the forming device through the tension roller 41 and the driving roller from top to bottom. In this way, the metal strip 20 wound into a coil occupies the space of the feeder 100 in the vertical direction, reducing the floor area of the feeder 100, making the structure of the feeder 100 more compact, and facilitating movement and assembly, and can reduce costs.

[0047] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0048] The above-described embodiments only represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
