Description

Technical Field

[0001] The utility model relates to a spraying device, in particular to a spraying device for lock production. Background Art

[0002] A lock is a device used to protect the safety of property, items or places. It uses a certain mechanism so that only people who hold a specific key or meet specific conditions can open it. The structure of a lock mainly includes a lock core, a shell, etc. To ensure the safety of the lock, the shell of the lock is usually made of metal. However, metal materials are easily corroded by rain and air when exposed to the environment. In order to extend the life of the lock, a layer of anti-rust paint is often sprayed on the surface of the lock shell during the production process of the lock.

[0003] In the existing lock spraying device, the lock is exposed to the air during the paint spraying process. When spraying paint, even if there is a negative pressure suction mechanism nearby, a large amount of mist paint liquid is still scattered in the air, which not only pollutes the workshop environment, but also causes great physical harm to workers if they inhale this part of the scattered paint.

[0029] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figures 1 to 3 A spraying device for lock production shown in the figure includes a group of conveying mechanisms 100, which transports the locks to be sprayed with paint liquid at a uniform speed through the spraying mechanism 500 arranged on the side of the conveying mechanism. It should be noted that in this scheme, the conveying mechanism 100 includes two groups of first frames 110, and the two groups of first frames are arranged opposite to each other at both ends. A transmission shaft 220 is rotatably mounted on the first frame, and a conveyor belt 140 is wound around the two transmission shafts. By driving the rotating shaft to rotate, the conveyor belt is driven to run. It should be noted that in the conveying mechanism in this scheme, a first motor 130 arranged on the side of one of the first frames is used to drive the transmission shaft to rotate. The first motor is coaxially connected to one of the transmission shafts to drive the transmission shaft connected to the first motor 130 to rotate as a driving shaft.

[0033] In addition, in order to fix the locks that need to be painted, a number of fixing mechanisms 200 are installed at equal intervals on the conveyor belt. The fixing mechanism can fix the locks after they are placed on it, preventing the locks from falling off the fixing mechanism when they move with the conveyor belt. Figure 2 As shown, the fixing mechanism includes an axle seat 210 mounted on the conveyor belt, in which a rotating shaft 220 can be rotatably inserted, and two pressing plates 230 are arranged above the rotating shaft. Specifically, the pressing plate is L-shaped, and the bending part can be rotatably connected to the end of the rotating shaft through an elastic hinge 240 to form a "child"-shaped structure whose upper end can be turned outward. Then, when the lock is set on the structure formed by the two pressing plates, the pressing plate is turned outward by the gravity of the lock and is stretched in the lock to prevent the structure from coming out of the lock. In addition, it should be noted that in this solution, when the lock set on the fixing mechanism 200 follows the conveyor belt to move to the bottom, the lock will no longer be pressed on the lower part of the pressing plate, and the pressing plate 230 can be reset under the action of the elastic hinge, and the lock can be easily taken off from the structure formed by the pressing plate and fall into the guide groove 400 below, so as to realize the collection of the lock after the painting is completed.

[0034] It should be noted that in the above steps, in order to ensure that the paint on the surface of the lock can dry quickly, a drying box 300 is also provided on the discharge side of the conveying mechanism. When the spraying mechanism completes spraying paint on the surface of the lock, the lock is transported by the conveying mechanism to the drying box, and then the paint surface is quickly dried in the drying box.

[0035] In addition, in this solution, in order to realize the closed painting operation on the surface of the lock, the specific structure of the spraying mechanism 500 arranged on the conveying mechanism in this solution includes a second frame 510, and a telescopic cylinder 520 is installed at the end of the second frame. The telescopic cylinder is arranged vertically, and a sealing cover 530 is installed at the lower end of the telescopic cylinder. When the lock set on the fixing mechanism moves to the bottom of the sealing cover, the telescopic cylinder drives the sealing cover to move down and sets the lock cover that needs to be sprayed with paint in it. It should be noted that if Figure 1 As shown, a plurality of atomizing nozzles 540 are evenly distributed on the outer surface of the enclosure, and the liquid outlet of the atomizing nozzle extends into the interior of the enclosure so that the sprayed paint mist can be evenly sprayed onto the surface of the lock covered by the enclosure. In addition, in order to stably provide paint mist, a paint storage box 560 is installed on the side of the second frame 510, and the paint storage box is provided with a high-pressure pump so that the stored paint liquid can be stably and pressured and pumped out and sent to the atomizing nozzle. In addition, it should be noted that in order to prevent the paint mist from overflowing from the gap between the lower edge of the enclosure and the conveyor belt, a circle of soft fur shielding curtains 550 is also arranged around the lower edge of the enclosure.

[0036] like Figure 1 As shown, a driving mechanism 600 is also provided on the opposite side of the spraying mechanism 500. Specifically, the driving mechanism 600 includes a third frame 610, on which a second motor 620 is mounted, and a driving wheel 630 is coaxially mounted on the output shaft of the second motor. Figure 2 As shown, the lower end of the rotating shaft in the fixing mechanism is coaxially connected to a rubber wheel 250. When the lock moves with the fixing mechanism to the bottom of the spraying mechanism, the driving wheel contacts the rim of the rubber wheel. When spraying, the second motor rotates and drives the lock sleeved on the fixing mechanism to rotate through the contact between the driving wheel and the rubber wheel, and finally realizes uniform spraying of the paint liquid on the surface of the lock.

[0037] In addition, in this solution, the conveyor belt is relatively long, and in order to prevent the conveyor belt from sagging due to gravity, which would cause the rubber wheel and the driving wheel to fail to engage, a support guide bar 700 is provided on both sides of the lower surface of the conveyor belt to provide smooth support for both sides of the conveyor belt so that it can be conveyed in a horizontal state.

[0038] Working principle: When the surface of the lock needs to be painted, the staff will first set the lock on an empty fixing mechanism. After being pressed by the lock, the two pressure plates on the fixing mechanism will flip outward and stretch on the inner wall of the lock to fix the lock, so that the lock can stably move synchronously with the fixing mechanism on the conveyor belt. As the lock moves to the bottom of the spraying mechanism, the conveyor belt stops moving, the telescopic cylinder in the spraying mechanism extends and drives the sealing cover to the outside of the lock. As the sealing cover is in place, the soft-haired shielding curtain at the bottom of the sealing cover abuts against the conveyor belt, thereby blocking the gap between the bottom of the sealing cover and the conveyor belt to prevent paint mist from overflowing from the gap below during painting. It should be noted that as the sealing cover is lowered into place, the paint storage box works to pump the paint liquid into the atomizing nozzle, and the paint liquid is sprayed onto the surface of the lock in an atomized form. In addition, in order to ensure uniform spraying of the paint liquid, after the lock is covered, the second motor in the driving mechanism rotates synchronously and drives the lock in the cover to rotate during painting, thereby achieving uniform spraying of the surface circumference.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
