[0002] In the prior art, as disclosed in the utility model with the application number 202321551024.7, a feeding device for a high-speed nail making machine is disclosed. In order to solve the problem that the existing feeding device for a high-speed nail making machine does not have the effect of active feeding, so that the staff needs to manually feed the material. Manual feeding not only has low work efficiency, but also reduces the work efficiency of the high-speed nail making machine. By setting a driving mechanism at the bottom of the rotating disk, automatic feeding can be carried out during the use of the nail making machine, increasing the work efficiency.

[0023] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the accompanying drawings. However, the embodiments of the present utility model are not limited thereto.

[0024] Such as Figures 1 - 4As shown in the figure, this embodiment provides a constant-speed feeding mechanism for a nail-making machine, which includes a base 1, a wire reel 2 that is rotatably installed on the top of the base 1 and stores steel coils, and a positioning column 3 that is vertically fixed on the top of the wire reel 2 to limit the steel coils. One end of the top of the base 1 is fixed with a support platform 4. An installation frame 5 is installed at one end of the top of the support platform 4 away from the wire reel 2. A conveyor belt 6 is installed between the installation frames 5. A motor 7 is installed on the outside of the installation frame 5, and the output end of the motor 7 is connected to the roller on the conveyor belt 6. A chute 8 is opened in the width direction on the top of the conveyor belt 6. Sliders 9 are slidably installed at both ends inside the chute 8. Return springs 10 are provided between the sliders 9 and the inner ends of the chute 8. Pressing blocks 11 are fixed on the tops of the sliders 9, and the two groups of pressing blocks 11 are symmetric with each other. The inclined surfaces of the pressing blocks 11 are located on the sides of the conveyor belt 6. Positioning plates 12 are symmetrically arranged on both sides of the top of the conveyor belt 6. A spacing adjustment mechanism is provided between the two groups of positioning plates 12. A pressing mechanism 16 is provided at one end of the top of the support platform 4 close to the wire reel 2.

[0025] Overall working principle: When in use, place the steel wire coil on the top of the wire reel 2, and the positioning column 3 passes through the center of the steel wire coil to limit the position of the steel wire coil. Then pass the steel wire through the inside of the pressing mechanism 16 and attach it to the top of the conveyor belt 6. Then connect the end of the steel wire to the nail-making machine. During the feeding process, install the positioning plate 12 according to the length of the nails produced by the nail-making machine. The length of the positioning plate 12 is the same as the length of the steel nails. When feeding, the conveyor belt 6 rotates. Since the pressing mechanism 16 has a certain resistance to the steel wire, when the steel wire is attached to the conveyor belt 6, the conveyor belt 6 will not drive the movement of the steel wire. Only when the two groups of pressing blocks 11 on the conveyor belt 6 clamp the steel wire under the extrusion of the positioning plate 12, will the steel wire be driven to move at this time. When the pressing block 11 is separated from the positioning plate 12, the fixing state of the steel wire is released. The moving length of the steel wire depends on the length of the positioning plate 12. The conveyor belt 6 continues to rotate and conveys the steel wire at a constant speed.

[0026] In this embodiment, anti-slip patterns are provided at the ends of the pressing blocks 11 away from the inclined surfaces, and the anti-slip patterns are perpendicular to the horizontal plane.

[0027] Local working principle: During the process of the pressing block 11 clamping the steel wire, the anti-slip patterns can increase the friction force when contacting the steel wire and ensure the stable movement of the steel wire.

[0028] In this embodiment, steel balls are rotatably installed at the ends of the pressing blocks 11 close to the inclined surfaces, and there are two groups of steel balls located on the same vertical line.

[0029] Local working principle: When the pressing block 11 is attached to the inside of the positioning plate 12 and slides along the length direction of the positioning plate, the steel balls can reduce the frictional resistance and reduce the wear of the positioning plate 12.

[0030] In this embodiment, the spacing adjustment mechanism includes a guide groove 13, a bidirectional screw 14, and a fixing rod 15. The guide groove 13 is opened at the top of the support table 4 along the width direction of the support table 4. Fixing rods 15 are slidably arranged at both ends inside the guide groove 13. A bidirectional screw 14 is rotatably installed between both ends of the guide groove 13. Both ends of the bidirectional screw 14 are respectively threadedly connected to the fixing rods 15. The fixing rod 15 is in an inverted L shape, and the top end of the fixing rod 15 is fixed to the positioning plate 12 by bolts.

[0031] Local working principle: During the conveying process of the steel wire, due to the different diameters of the steel wires, by rotating the bidirectional screw 14, the spacing between the two fixing rods 15 can be changed, thereby adjusting the position of the positioning plate 12. When the spacing of the positioning plate 12 is small, there is a small spacing between the two squeezing blocks 11 when they are clamped, and the thinner steel wire can be squeezed and clamped. When the spacing of the positioning plate 12 is large, there is a large spacing between the two squeezing blocks 11 when they are clamped, and the thicker steel wire can be clamped and conveyed. In addition, during use, in order to adjust the conveying speed, the positioning plates 12 of different lengths can be replaced. The positioning plate 12 is threadedly connected to the fixing rod 15, making the replacement more convenient.

[0032] In this embodiment, both ends of the bidirectional screw 14 extend to the sides of the support table 4, and adjusting blocks are fixed to both ends of the bidirectional screw 14.

[0033] Local working principle: When adjusting the bidirectional screw 14, manually control the rotation of the adjusting block for adjustment.

[0034] In this embodiment, the pressing mechanism 16 includes vertical plates 17, a fixing roller 18, a strip-shaped groove 19, a limiting block 20, a pressing spring 21, and a pressing roller 22. The vertical plates 17 are symmetrically fixed on both sides of the top of the support table 4. A fixing roller 18 is rotatably installed at the bottom between the two vertical plates 17. Strip-shaped grooves 19 are vertically opened at the top outside the vertical plates 17. Limiting blocks 20 are slidably installed inside the strip-shaped grooves 19. Pressing springs 21 are arranged between the limiting blocks 20 and the upper and lower ends of the vertical plates 17. A pressing roller 22 is rotatably installed between the two limiting blocks 20, and the surface of the pressing roller 22 is in contact with the surface of the fixing roller 18.

[0035] Local working principle: During the conveying process of the steel wire, the steel wire passes through between the pressing roller 22 and the fixing roller 18. Using the pressure of the pressing spring 21, it is ensured that the pressing roller 22 closely adheres to the top of the steel wire, and it can adapt to steel wires of different diameters.

[0036] In this embodiment, V-shaped grooves are circumferentially opened at the middle positions on the outer sides of the fixing roller 18 and the pressing roller 22.

[0037] Local working principle: During the process of wire conveying, the wire is limited inside the V-shaped groove, which increases the contact area with the wire and has higher stability.

[0038] The above are only further embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and concept of the present utility model, makes equivalent substitutions or changes, all belong to the protection scope of the present utility model.
