Description

Technical Field

[0001] This utility model relates to the field of metal spraying, specifically a reciprocating coating machine for spraying. Background Technology

[0002] Metal spraying is a material protection technology that forms a functional coating by spraying molten or semi-molten metal particles at high speed onto the surface of a substrate. Its core principle is to use a high-temperature heat source (such as an electric arc, plasma, or combustion flame) to melt metal wires or powders, and accelerate the particles with compressed gas so that they impact the substrate at supersonic speeds to form a dense metallurgical bonding layer.

[0003] Chinese patent CN219804836 U discloses a reciprocating coating machine for spraying. It is equipped with a telescopic cylinder and a worktable. The bottom of the worktable is fixed to the top of the telescopic cylinder. The telescopic cylinder can push the worktable up and down to adjust the height of the workpiece on the worktable surface. Then, an electric push rod is provided at the bottom of the storage box. The bottom of the electric push rod is equipped with a spraying component. The up and down extension of the electric push rod can push the spraying component up and down to adjust the spraying component to a suitable height for spraying the workpiece.

[0004] In summary, the above structure extracts the coating liquid from the coating cylinder through the spraying component and sprays it onto the outer surface of the metal. The coating liquid is mainly a dispersion system composed of various components such as resin, pigment, solvent, filler, and additives. The density and particle size of each component are different. During the spraying process, prolonged standing will cause stratification due to its own gravity, which will affect the subsequent spraying effect. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a reciprocating coating machine for spraying, so as to solve the technical problem that the spraying liquid will separate due to its own gravity when it is left to stand for a long time during the spraying process, which will affect the subsequent spraying effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reciprocating coating machine for spraying, comprising a base and a frame, the frame being located at the top of the base, wherein a spraying table is also provided at the top of the base, a drive assembly is provided at the top of the frame, wherein the output end of the drive assembly is connected to a spraying assembly, a fixed gear cooperating with the spraying assembly is rotatably arranged inside the frame, and a spraying cylinder cooperating with the spraying assembly is provided inside the base, wherein a stirring assembly cooperating with the fixed gear is rotatably arranged inside the spraying cylinder.

[0007] By adopting the above technical solution, during the reciprocating movement of the spraying component, the stirring component inside the spraying cylinder rotates in both directions under the action of the fixed gear and the transmission mechanism. During this process, the spraying liquid inside the spraying cylinder is disturbed and mixed, ensuring that the device can carry out spraying work for a long time, effectively preventing the layering of the liquid over a long period of time, and further improving the overall spraying effect.

[0008] The present invention is further configured such that a transmission mechanism is connected to one side of the fixed gear, wherein a spur bevel gear is connected to one end of the transmission mechanism, and a side bevel gear meshes with one side of the spur bevel gear, and the top of the side bevel gear is connected to the stirring assembly.

[0009] Preferably, during the rotation of the fixed gear through the rack, the spur bevel gear will be driven to rotate, and the meshing of the spur bevel gear and the side bevel gear will drive the stirring mechanism inside the spray gun to rotate.

[0010] The present invention is further configured such that a sliding groove is provided on the inner side of the frame, and a slider that cooperates with the sliding groove is provided on one side of the spraying component, and one end of the slider is connected to a toothed rod that meshes with a fixed gear.

[0011] Preferably, the cooperation between the slide and the slider allows the spraying component to slide stably within the frame, effectively preventing the spraying component from tilting during operation. During the sliding process, the slider drives the rack to move, thereby driving the fixed gear to rotate.

[0012] The present invention is further configured such that the stirring assembly includes a stirring rod and stirring blades, the top of the side bevel gear is connected to the stirring rod, and an array of stirring blades are evenly arranged on the outer wall of the stirring rod.

[0013] Preferably, the rotation of the side bevel gear will drive the top stirring rod to rotate, which, together with the stirring blades on the outer wall, will agitate the spray liquid in the spraying barrel, further improving the mixing effect of the spray liquid itself.

[0014] The present invention is further configured such that the top of the spraying station is roughened, and an array of electric suction cups are evenly distributed on the top of the spraying station.

[0015] Preferably, the rough surface increases the friction between the spraying station and the metal parts, preventing the metal parts from shifting position during the spraying process. Furthermore, the electric suction cup on the spraying station limits the position of the metal parts, thereby fixing metal parts of different sizes and ensuring the subsequent spraying effect.

[0016] The present invention is further configured such that the transmission mechanism includes a driving disc, a transmission belt and a driven disc, the driving disc and the driven disc are connected by a transmission belt, one end of the driving disc is connected to a fixed gear, and one end of the driven disc is connected to a spur bevel gear, and the diameter of the driving disc in the transmission mechanism is larger than the diameter of its driven disc.

[0017] Preferably, during the rotation of the fixed gear via the rack, it drives the driving disc at one end to rotate. With the cooperation of the transmission belt, the driven disc is driven to rotate, which in turn drives the spur bevel gear to rotate. Since the diameter of the driving disc in the transmission mechanism is larger than the diameter of its driven disc, when the rack drives the fixed gear to rotate several times, the driven disc will drive the spur bevel gear to rotate several times more times, thereby increasing the stirring speed of the stirring component in the spray gun.

[0018] The present invention is further configured such that the driving component is a cylinder, and the cylinder is used to drive the spraying component at the output end to reciprocate in the vertical direction.

[0019] Preferably, the spraying assembly itself can be height-adjusted by a cylinder, thereby enabling spraying of metal parts of different thicknesses and improving the overall practicality of the device.

[0020] The present invention is further configured such that a corrugated pipe is connected between the spraying cylinder and the spraying assembly, and both ends of the corrugated pipe are rigid pipes.

[0021] Preferably, the corrugated pipe design prevents the pipe from bending when the spraying assembly moves up and down, ensuring the stability of the internal spray liquid flow. Furthermore, the rigid pipes at both ends facilitate stable driving of the corrugated pipe during stretching and contraction.

[0022] The present invention is further configured such that a controller is provided on one side of the base to cooperate with the electric suction cup, wherein the controller and the electric suction cup are electrically connected.

[0023] Preferably, the controller allows staff to easily control the electric suction cup, ensuring the retrieval of metal parts.

[0024] The present invention is further configured such that the inner wall of the spraying cylinder is smooth.

[0025] Preferably, the smooth surface effectively prevents the sprayed liquid from sticking, making it easier to clean and replace the sprayed liquid later.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model has a spraying table set on the top of the base. The metal parts on the spraying table are limited by an electric suction cup to fix metal parts of different sizes, so as to ensure the subsequent spraying effect. The spraying component itself can be height adjusted by a cylinder to spray metal parts of different thicknesses, thereby improving the overall practicality of the device.

[0028] 2. This utility model has a toothed rod slidably installed on one side of the spraying component. During the up-and-down reciprocating movement of the spraying component, the stirring component inside the spraying cylinder rotates in both directions under the action of the fixed gear and the transmission mechanism. During this process, the spraying liquid in the spraying cylinder is disturbed and mixed, ensuring that the device can carry out spraying work for a long time, effectively preventing the layering of the liquid over a long period of time, and further improving the overall spraying effect.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of this utility model will be described below based on its overall structure.

[0039] Example 1: Please refer to Figures 1-6 The reciprocating coating machine for spraying includes a base 1, a frame 2, a spraying component 5, a limiting mechanism, and a stirring mechanism. A spraying table 6 is also provided on the top of the base 1. The operator places the metal parts to be sprayed on the top of the spraying table 6, and then starts the cylinder 3 on the top of the frame 2. Under the action of the cylinder 3, the spraying component 5 at the output end slides downward. Since a sliding groove 4 is provided on the inner side of the frame 2, a slider 9 that cooperates with the sliding groove 4 is provided on one side of the spraying component 5. A toothed rod 11 that meshes with a fixed gear 12 is connected to one end of the slider 9. With the cooperation of the sliding groove 4 and the slider 9, the spraying component 5 slides stably within the frame 2, effectively preventing the spraying component 5 from tilting during operation. During the sliding process, the slider 9 drives the toothed rod 11 to move, thereby driving the fixed gear 12 to rotate.

[0040] Since a transmission mechanism 10 is connected to one side of the fixed gear 12, and a spur bevel gear 14 is connected to one end of the transmission mechanism 10, and a side bevel gear 15 is meshed on one side of the spur bevel gear 14, and the top of the side bevel gear 15 is connected to the stirring assembly 16, when the fixed gear 12 rotates through the rack 11, it will drive the spur bevel gear 14 to rotate. Through the meshing of the spur bevel gear 14 and the side bevel gear 15, the stirring assembly 16 in the spraying cylinder 13 is driven to rotate. In this process, the spray liquid in the spraying cylinder 13 is disturbed and mixed during spraying, ensuring that the device can carry out spraying work for a long time, effectively preventing the layering of the liquid over a long period of time, and further improving the overall spraying effect.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The top of the spraying station 6 is roughened, and an array of electric suction cups 7 are evenly distributed on the top of the spraying station 6. The roughened design increases the friction between the spraying station 6 and the metal parts, preventing the metal parts from shifting position during the spraying process. The electric suction cups 7 on the spraying station 6 limit the position of the metal parts, thereby fixing metal parts of different sizes and ensuring the subsequent spraying effect.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 A corrugated pipe 8 is connected between the spraying cylinder 13 and the spraying assembly 5, and both ends of the corrugated pipe 8 are rigid pipes. The corrugated pipe 8 is designed so that the pipe itself will not bend when the spraying assembly 5 moves up and down, thus ensuring the stability of the internal spraying liquid flow. The rigid pipes at both ends facilitate the stable driving of the corrugated pipe 8 during the stretching and shrinking process.

[0043] Example 2: Please refer to Figure 3 The reciprocating coating machine for spraying shown includes a transmission mechanism 10 comprising a drive disc, a transmission belt, and a driven disc. A fixed gear 12 is connected to one end of the drive disc, and a spur bevel gear 14 is connected to one end of the driven disc. As the fixed gear 12 rotates via the rack 11, it drives the drive disc to rotate. With the help of the transmission belt, the driven disc rotates, which in turn drives the spur bevel gear 14 to rotate. Since the diameter of the drive disc in the transmission mechanism 10 is larger than the diameter of its driven disc, when the rack 11 drives the fixed gear 12 to rotate several times, the driven disc drives the spur bevel gear 14 to rotate several times. This increases the stirring speed of the stirring assembly 16 in the spraying cylinder 13, further preventing the coating from separating over a long period of time.

[0044] In practical operation, this invention works as follows: The metal parts to be coated are placed on top of the spraying station 6 and then fixed in place by the electric suction cup 7. Simultaneously, the cylinder 3 drives the spraying assembly 5 to slide downwards, thus spraying the metal parts on top of the spraying station 6. During the downward sliding of the spraying assembly 5, the slider 9 on one side of the spraying assembly 5 drives the rack 11 downwards, thereby rotating the fixed gear 12. Through the meshing of the transmission mechanism 10 and the bevel gear, the stirring assembly 16 is rotated. Since the stirring assembly 16 is located inside the spraying cylinder 13, the reciprocating sliding of the spraying assembly 5 causes the stirring assembly 16 inside the spraying cylinder 13 to rotate in both directions. This process agitates and mixes the spray liquid inside the spraying cylinder 13 during spraying, ensuring that the device can perform spraying operations for a long time and effectively preventing long-term separation.
