Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts processing, in particular to a painting device for mechanical parts nails. Background Art

[0002] Industry uses a wide variety of mechanical parts, both large and small. Nails are a common type of part, primarily used to fasten or connect objects. A nail has a thin, round, rod-shaped body with a flat, round head at the top and a sharp tip at the bottom. When in use, the nail is placed upright on an object, with the tip resting against the object. Hitting the head with a hammer drives the body of the nail into the object, securing or connecting the objects. The body of the nail is a smooth, thin, round rod. When in use, the hammer strikes the head of the nail, driving the entire body of the nail into the object.

[0003] To prevent nails from rusting, they are typically painted to protect them and extend their service life. A Chinese patent application, "A spraying device for nail surface treatment," has been published with publication number CN214132369U. In this device, a spray gun at the lower end of a liquid reservoir automatically sprays the nails on the top of a spray plate as the reservoir moves. This allows for a wider, more uniform spray coverage and higher efficiency.

[0004] In the prior art, when spraying nails, the nails are positioned on the spray plate, and only the liquid tank and the spray gun at the bottom of the tank can move. Therefore, during the spraying process, the side of the nail close to the spray plate is difficult to spray, while the side of the nail away from the spray plate can be sprayed. This results in uneven spraying on the surface of the nail, reducing the spraying effect of the nail. In view of this, we propose a painting device for nails of mechanical parts. Utility Model Content

[0005] The purpose of the utility model is to provide a painting device for mechanical parts nails, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A painting device for nails of mechanical parts, comprising a box body, four supporting legs are evenly fixedly connected to the bottom of the box body, a painting device is provided on the box body, a shielding device is provided on the painting device, the painting device comprises a machine box, a driving motor, a rotating shaft, a turntable, a discharge barrel, a nail hole, a support sheet, and a brush, the box body is fixedly connected to the center of the top surface of the inner wall of the box body, the driving motor is fixedly installed in the box body, one end of the rotating shaft is fixedly connected to the output end of the driving motor through a coupling, the rotating shaft passes through the box body and is rotatably connected to the box body, the turntable is fixedly connected to the top of the rotating shaft, the shielding device is arranged on the top of the turntable, the discharge barrel The barrel passes through the turntable and is rotatably connected to the turntable. The nail hole is opened at the center of the bottom of the discharge barrel. The support piece is fixedly connected to the bottom surface of the inner wall of the discharge barrel, and the support pieces are evenly arranged around the nail hole. The bristles are evenly fixedly connected to the inner wall annular surface of the box body. The painting device also includes a clamping ring, a clamping groove, an outer gear ring, and an inner gear ring. The clamping ring is fixedly connected to the outer wall annular surface of the discharge barrel. The clamping groove is opened in the through hole of the turntable penetrated by the discharge barrel. The clamping ring is clamped and slidably connected in the clamping groove. The outer gear ring is fixedly sleeved on the outer wall annular surface of the discharge barrel, and the inner gear ring is fixedly connected to the inner wall annular surface of the box body, and the outer gear ring is meshed with the inner gear ring.

[0008] Preferably, the shielding device includes a rotating rod, a wheel disc, and a baffle plate. One end of the rotating rod is rotatably connected to the center of the top surface of the rotating disc through a bearing, the wheel disc is fixedly connected to the other end of the rotating rod, and the baffle plate is fixedly connected to the rotating rod. The bottom surface of the baffle plate is flush with the top surface of the discharge barrel, and the baffle plate is provided with a slot corresponding to the position of the discharge barrel.

[0009] Preferably, the top surface of the chassis is provided with a smooth convex surface. By providing the smooth convex surface, the paint dropped on the chassis can slide down along the inclined smooth surface, avoiding the paint accumulation on the top of the chassis to dry and condense, which is difficult to clean. The connection between the rotating shaft and the chassis is provided with a sealing ring. By providing the sealing ring, the paint is prevented from seeping into the gap between the rotating shaft and the chassis. After solidification, the rotating shaft and the chassis are bonded and fixed, affecting the rotation of the rotating shaft.

[0010] Preferably, the top surface of the support piece is inclined and convex. Such a setting can reduce the contact area between the support piece and the end of the nail, thereby reducing the support piece's obstruction of the outer surface of the nail, making the painting surface wider and the painting effect better. The painting device also includes a limiting flow plate, which is fixedly connected to the support piece. The limiting flow holes are evenly arranged on the limiting flow plate. By setting the limiting flow plate and the limiting flow holes, the paint can be blocked, and the flow of the paint entering the nail hole can be controlled, so that the paint can flow down slowly, so that the paint can be applied more evenly using the brush.

[0011] Preferably, the outer surfaces of the support plate and the flow limiting plate, as well as the inner walls of the discharge barrel and the nail hole are coated with a smooth oil film. By coating the support plate, the flow limiting plate, the discharge barrel and the nail hole to increase the surface smoothness, paint is not easy to adhere to them, and a small amount of paint adhered to them is easy to fall off after drying and solidifying, which is convenient for cleaning.

[0012] Preferably, the shielding device also includes a heating block, which is evenly embedded on the baffle. When the baffle completely blocks the discharge barrel, the heating block is located directly above the discharge barrel. By setting the heating block, after the painting work is completed, the heating block is used to heat and dry the inside of the discharge barrel, so that the paint on the end face of the nail dries quickly and is easy to remove, which can reduce the residence time of the nail in the discharge barrel and thereby improve the nail painting rate.

[0013] Preferably, slots are evenly and fixedly connected on the annular surface of the outer wall of the box body, and a material picking rod is inserted in each of the slots. The end of the material picking rod is fixedly connected to a magnet. By setting the slots and the material picking rod, after the nails are painted, the magnetic force of the magnet on the material picking rod is used to suck the nails, thereby easily removing the nails inserted into the discharge barrel.

[0014] Preferably, the bottom surface of the inner wall of the box is a smooth concave surface, and leakage holes are evenly opened at the lowest part of the concave part of the box. By setting the smooth concave surface and leakage holes, the dripping paint slides down the inclined surface and is discharged from the leakage holes, which is convenient for recovery.

[0015] By means of the above technical solution, the present invention provides a painting device for nails of mechanical parts, which has at least the following beneficial effects:

[0016] (1) The utility model sets a painting device, inserts the nail into the discharge barrel, and pours the paint into the discharge barrel so that the paint slides slowly along the surface of the nail. The motor drives the turntable to rotate, so that the discharge barrel moves in a circular motion around the rotating shaft, so that the bristles continuously paint the nail rod, and the sliding paint is evenly applied to the nail rod. The inner gear ring blocks the outer gear ring with the inner core, so that the outer gear ring and the discharge barrel rotate together, thereby driving the nail to rotate, making the painting more uniform.

[0017] (2) The utility model sets a shielding device, which can drive the baffle to rotate by rotating the wheel, so as to adjust the angle of the baffle. During the process of taking and placing nails and filling paint, the notch of the baffle is aligned with the position of the discharge barrel, and the top of the discharge barrel is opened; during the painting process, the notch of the baffle is misaligned with the discharge barrel, so that the baffle blocks the top of the discharge barrel, thereby avoiding the centrifugal force generated during the rotation of the turntable, which causes the paint in the discharge barrel to overflow, resulting in waste of resources and easy pollution of the surrounding environment.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0026] See also Figure 1 - Figure 5 As shown, the utility model provides a technical solution:

[0027] A painting device for nails of mechanical parts includes a box body 1, four supporting legs 2 are evenly fixedly connected to the bottom of the box body 1, a painting device 3 is provided on the box body 1, and a shielding device 4 is provided on the painting device 3. Slots 5 are evenly fixedly connected to the annular surface of the outer wall of the box body 1, and a feeding rod 6 is inserted in each slot 5. The end of the feeding rod 6 is fixedly connected to a magnet. By setting the slots 5 and the feeding rod 6, after the nails are painted, the magnetic force of the magnet on the feeding rod 6 is utilized to suck the nails, thereby easily removing the nails inserted into the discharge barrel 305. The bottom surface of the inner wall of the box body 1 is a smooth concave surface, and leakage holes 7 are evenly opened at the lowest part of the concave portion of the box body 1. By setting the smooth concave surface and the leakage holes 7, the dripping paint slides down the inclined surface and is discharged from the leakage holes 7, which is convenient for recycling.

[0028] Furthermore, the painting device 3 includes a chassis 301, a drive motor 302, a rotating shaft 303, a turntable 304, a discharge barrel 305, a nail hole 308, a support piece 309, and a brush 313. The chassis 301 is fixedly connected to the center of the top surface of the inner wall of the box body 1, and the drive motor 302 is fixedly installed in the chassis 301. One end of the rotating shaft 303 is fixedly connected to the output end of the drive motor 302 through a coupling. The rotating shaft 303 passes through the chassis 301 and is rotatably connected to the chassis 301. The top surface of the chassis 301 is a smooth convex surface. By setting the smooth convex surface, the paint dropped on the chassis 301 can slide down along the inclined smooth surface, thereby preventing the paint from accumulating on the top of the chassis 301 and drying and condensing, making it difficult to Cleaning, a sealing ring is provided at the connection between the rotating shaft 303 and the chassis 301. The sealing ring is provided to prevent paint from seeping into the gap between the rotating shaft 303 and the chassis 301. After solidification, the rotating shaft 303 and the chassis 301 are bonded and fixed, affecting the rotation of the rotating shaft 303. The turntable 304 is fixedly connected to the top of the rotating shaft 303, and the shielding device 4 is set on the top of the turntable 304. The discharge barrel 305 passes through the turntable 304 and is rotatably connected to the turntable 304. The nail hole 308 is opened at the bottom center of the discharge barrel 305, and the support piece 309 is fixedly connected to the bottom surface of the inner wall of the discharge barrel 305, and the support pieces 309 are evenly arranged around the nail hole 308, and the bristles 313 are evenly fixedly connected to the inner wall ring surface of the box body 1.

[0029] Furthermore, the top surface of the support piece 309 is inclined, and the top surface of the support piece 309 is convex. This arrangement can reduce the contact area between the support piece 309 and the end of the nail, thereby reducing the shielding of the support piece 309 on the outer surface of the nail, making the painting surface wider and the painting effect better. The painting device 3 also includes a limiting flow plate 310, which is fixedly connected to the support piece 309. The limiting flow holes are evenly arranged on the limiting flow plate 310. By setting the limiting flow plate 310 and the limiting flow holes, the paint can be The support piece 309 and the limiting plate 310 are blocked to control the flow of paint into the nail hole 308, so that the paint flows slowly, so that the paint can be brushed more evenly with the bristles 313. The outer surfaces of the support piece 309 and the limiting plate 310 and the inner walls of the discharge barrel 305 and the nail hole 308 are coated with a smooth oil film. By coating the support piece 309, the limiting plate 310, the discharge barrel 305 and the nail hole 308 with a film to increase the surface smoothness, it is difficult for paint to adhere to them. A small amount of paint that adheres to them can also be easily removed after drying and solidification, which is convenient for cleaning.

[0030] In addition, the painting device 3 also includes a snap ring 306, a slot 307, an outer gear ring 311, and an inner gear ring 312. The snap ring 306 is fixedly connected to the outer wall ring surface of the discharge barrel 305, and the slot 307 is opened in the through hole of the turntable 304 penetrated by the discharge barrel 305. The snap ring 306 is snapped and slidably connected in the slot 307. The outer gear ring 311 is fixedly sleeved on the outer wall ring surface of the discharge barrel 305, and the inner gear ring 312 is fixedly connected to the inner wall ring surface of the box body 1. The outer gear ring 311 is meshed with the inner gear ring 312.

[0031] In addition, the shielding device 4 includes a rotating rod 401, a wheel 402, and a baffle 403. One end of the rotating rod 401 is rotatably connected to the center of the top surface of the rotating disk 304 through a bearing, the wheel 402 is fixedly connected to the other end of the rotating rod 401, and the baffle 403 is fixedly connected to the rotating rod 401. The bottom surface of the baffle 403 is flush with the top surface of the discharge barrel 305, and a notch corresponding to the position of the discharge barrel 305 is opened on the baffle 403. The shielding device 4 also includes a heating block 404. The heating blocks 404 are evenly embedded on the baffle 403. When the baffle 403 completely blocks the discharge barrel 305, the heating blocks 404 are located directly above the discharge barrel 305. By setting the heating blocks 404, after the painting work is completed, the heating blocks 404 heat the inside of the discharge barrel 305 to heat and dry it, so that the paint on the end surface of the nail dries quickly and is easy to take out, which can reduce the residence time of the nail in the discharge barrel 305, thereby improving the nail painting rate.

[0032] The electrical components and devices appearing in this embodiment are all existing devices known in the art, and the content protected by this utility model does not involve improvements to the internal structures of these devices. The electrical components and devices appearing in this embodiment are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc.

[0033] When using the paint coating device for mechanical parts nails of the present invention, the entire device is placed stably on a horizontal operating table, and the paint recovery container is placed directly below the box body 1, so that the feed port of the collection container is directly below the leak hole 7. The wheel 402 is rotated to rotate the rotating rod 401, thereby driving the baffle 403 to rotate until the notch of the baffle 403 corresponds to the discharge barrel 305. The wheel 402 is then stopped, and the top opening of the discharge barrel 305 is exposed.

[0034] Insert the nail to be painted downward into the discharge barrel 305 with the end facing upward, so that the end of the nail is stuck on the support piece 309. The nail shaft passes through the nail hole 308 and enters the interior of the box 1, contacting the bristles 313. After all the nails are inserted into the discharge barrels 305, paint is injected into each discharge barrel 305 in turn. After entering the discharge barrel 305, the paint is blocked by the end of the nail, the support piece 309, and the flow restriction plate 310, and slowly flows out of the flow restriction hole and slides down the nail shaft. After the paint is injected, the wheel 402 is turned to rotate the baffle plate 403, so that the notch of the baffle plate 403 is misaligned with the discharge barrel 305, so that the baffle plate 403 seals the discharge barrel 305.

[0035] The drive motor 302 is started, which drives the turntable 304 to rotate via the rotating shaft 303, thereby causing the discharge barrel 305 to perform a circular motion around the rotating shaft 303. The bristles 313 on the inner wall of the box body 1 continuously scrape the nail shaft, evenly coating the paint that slides off onto the annular surface of the shaft. Excess paint drips onto the bottom surface of the inner wall of the box body 1, slides down along the bottom surface to the lowest point, and finally falls into a pre-prepared collection container through the leak hole 7. At the same time, during the circular motion of the discharge barrel 305, the outer ring gear 311 is blocked by the inner ring gear 312 and rotates, thereby driving the discharge barrel 305 as a whole to rotate, causing the nail inserted into the discharge barrel 305 to rotate, so that the bristles 313 more evenly apply paint to the outer surface of the nail.

[0036] The driving motor 302 works for five minutes. After the paint in the discharge barrel 305 has flowed out, the driving motor 302 is turned off to stop the operation of the painting device 3 as a whole. The heating block 404 is started to heat the inside of the discharge barrel 305 for three minutes. After the paint on the end of the nail is dried and solidified, the heating block 404 is turned off and the wheel 402 is rotated to expose the top of the discharge barrel 305. The feeding rod 6 is pulled out from the slot 5. The magnet end of the feeding rod 6 is used to magnetically attract the end of the nail, thereby taking the nail out of the discharge barrel 305 and letting the nail rod dry.

[0037] After the nails are taken out, new nails to be painted are inserted and the above steps are repeated to continue the nail painting work. After all nails are painted, the inside of the discharge barrel 305 is rinsed and the whole device is dried and stored.
