Description

Technical Field

[0001] This application relates to the field of metal nail processing apparatus, and in particular to a metal nail sharpening apparatus. Background Technology

[0002] A metal nail is a metal product used to fasten objects. It consists of three parts: a nail head, a nail shaft, and a nail tip. It is generally driven into wood or cement using a hammer or air gun. It is widely used in various fields such as industry, agriculture, construction, and civil use, and has the advantages of simple processing, convenient use, and rapid fastening.

[0003] During the production of metal nails, they need to be sharpened. Existing technology, such as the patent document with authorization announcement number CN220516375U, discloses a sharpening machine for processing high-strength metal nails. This solution involves mounting a grinder with a conical groove on the output shaft of a motor. During the sharpening process, the tip of the metal nail is inserted into the conical groove, and the motor drives the grinder to rotate, thus achieving the sharpening function.

[0004] The shortcomings of existing technology are that it can only fix and sharpen a single metal nail, which is inefficient, complex in structure, and consumes a lot of energy, which is not in line with production efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this application provides a metal nail sharpening device.

[0006] The metal nail sharpening device provided in this application adopts the following technical solution:

[0007] A metal nail sharpening device, comprising:

[0008] The base includes a base plate, two end plates vertically fixed to the base plate, and two side plates fixed to the end plates.

[0009] A grinding mechanism includes a grinding roller and a first motor. The grinding roller is rotatably connected to the end plate, and the first motor is used to drive the grinding roller to rotate.

[0010] The conveying mechanism includes two rotating rollers, a conveyor belt, and a second motor. The rotating rollers are rotatably connected to the side plate, the conveyor belt is disposed on the rotating rollers, and the second motor is used to drive the rotating rollers to rotate.

[0011] A support plate, fixedly mounted on the end plate and parallel to the grinding roller, is used to support metal nails;

[0012] The pressure plate is fixedly installed on the side plate and fits against the inner side of the conveyor belt.

[0013] A further technical solution is that the tray and the pressure plate are provided with through grooves for embedding nail heads.

[0014] A further technical solution is that one end of the tray extends to the outside of the end plate.

[0015] A further technical solution is that the pallet and the pressure plate are parallel and inclined, and one end of the pallet extending to the outside of the end plate is higher than the other end.

[0016] A further technical solution is that sandpaper is attached to the outer circumferential surface of the grinding roller.

[0017] A further technical solution is that the grit number of the sandpaper gradually increases from one end of the sanding roller to the other end.

[0018] Compared with the prior art, this application includes the following beneficial technical effects:

[0019] By setting up a pallet, pressure plate, and conveyor belt, the conveyor belt can press the metal nails together and move the metal nails toward the other end of the pallet by moving the conveyor belt. The grinding roller is connected to the end plate and contacts the tip of the metal nail. The rotation of the grinding roller can grind and sharpen the tips of multiple metal nails on the pallet, thereby greatly improving the efficiency of the metal nail sharpening process.

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise expressly specified. "Several" means one or more, unless otherwise expressly specified.

[0025] The technical solutions in this application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a metal nail sharpening device. Please refer to... Figure 1 and Figure 2 The device includes a base, a grinding mechanism, a conveying mechanism, a pallet 41, and a pressure plate 42.

[0027] The base includes a base plate 11, two end plates 12 vertically fixed to the base plate 11, and two side plates 13 fixed to the end plates 12. The grinding mechanism includes a grinding roller 22 and a first motor 21. The grinding roller 22 is rotatably connected to the end plate 12, and the first motor 21 drives the grinding roller 22 to rotate. The conveying mechanism includes two rotating rollers 31, a conveyor belt 32, and a second motor 33. The rotating rollers 31 are rotatably connected to the side plates 13, and the conveyor belt 32 is mounted on the rotating rollers 31. The second motor 33 drives the rotating rollers 31 to rotate. A support plate 41 is fixedly mounted on the end plate 12 and parallel to the grinding rollers 22, and is used to support metal nails. A pressure plate 42 is fixedly mounted on the side plates 13 and fits against the inner side of the conveyor belt 32.

[0028] Specifically, each of the two end plates 12 has a first through hole 14 for the metal nail to pass through laterally, and a second through hole 15 communicating with the first through hole 14. The second through hole 15 is used to house the conveying mechanism. Two side plates 13 are installed on the sides of the second through hole 15 to provide support for the roller 31 and the second motor 33.

[0029] In practice, the metal nail to be sharpened is placed flat on the pallet 41, and the outer side of the conveyor belt 32 abuts against the metal nail. Driven by the second motor 33, the conveyor belt 32 moves, and the metal nail on the pallet 41 rolls towards the other end of the pallet 41 under the pressure of the conveyor belt 32. Simultaneously, the conveyor belt 32 is prevented from deforming by the pressure plate 42. During the movement, the tip of the metal nail remains in contact with the grinding roller 22, which rotates continuously under the drive of the first motor 21, thus sharpening the tip of the metal nail. Multiple metal nails can be placed on the pallet 41 for simultaneous sharpening, greatly improving the efficiency of the sharpening operation.

[0030] Furthermore, the support plate 41 and pressure plate 42 are provided with through slots 43 for embedding nail heads. When the metal nail rolls on the support plate 41, its nail head is suspended in the through slot 43, and the shaft of the metal nail fully abuts against the support plate 41, preventing the nail head support from tilting and shifting during movement. At the same time, the nail head abutting against the through slot 43 can prevent the metal nail from moving axially due to friction between the grinding roller 22 and the metal nail, and prevent the metal nail from falling off the support plate 41.

[0031] Furthermore, one end of the pallet 41 extends to the outside of the end plate 12, which facilitates the placement of metal nails on the pallet 41 and effectively prevents fingers from being caught between the pallet 41 and the conveyor belt 32, thus improving safety.

[0032] Furthermore, the pallet 41 and the pressure plate 42 are parallel and inclined, with one end of the pallet 41 extending beyond the end plate 12 higher than the other end. Thus, after a metal nail is placed on the pallet 41, its inclined structure allows it to automatically roll towards the other side. When the metal nail enters the position between the conveyor belt 32 and the idler roller, it moves towards the other side under the clamping force of the conveyor belt 32, further improving safety.

[0033] Furthermore, sandpaper is attached to the outer circumferential surface of the grinding roller 22, and the grit of the sandpaper gradually increases from one end of the grinding roller 22 to the other. When the metal nail first contacts the grinding roller 22, the grit of the sandpaper is smaller, which can be used for coarse grinding of the metal nail; when the metal nail moves to the rear half or end of the support plate 41, the grit of the sandpaper is larger, which can be used for fine grinding of the metal nail, thereby improving the sharpening effect of the metal nail.

[0034] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
