Description

Technical Field

[0001] This utility model relates to the technical field of parts spraying devices, specifically a spraying device for injection molded parts that is easy to flip. Background Technology

[0002] Injection molded parts are plastic products manufactured using injection molding technology. Surface coating of injection molded parts can effectively prevent scratches and wear, resist the erosion of the product by moisture, dust, chemicals and other external environmental factors, and extend the product's service life.

[0003] Upon investigation, a utility model patent (publication number: CN217569263U) discloses a spraying device for precision injection molding parts production and processing. A spraying connector is fixedly installed on the inner wall of the upper and lower ends of the spraying tank. The outer surface of the spraying connector is provided with a mounting hole, and an atomizing nozzle is fixedly installed inside the mounting hole. An air guide pipe is fixedly connected to the middle position of the side surface of the spraying tank. A liquid storage tank is fixedly installed on the side surface of the spraying tank. The air outlet of the air guide pipe is located at the bottom of the liquid storage tank. A drive mechanism is fixedly installed at the middle position of the lower end face of the spraying tank.

[0004] The aforementioned patent describes a method for spraying injection molded parts by placing them inside a spray tank. This allows for circumferential spraying of the parts. However, this device can only spray a single injection molded part. When multiple injection molded parts are placed inside the spray tank, although the circumferential rotation drive mechanism can achieve circumferential rotation, only the side of the multiple injection molded parts that is close to the inner wall of the tank can be sprayed with paint. This reduces the spraying efficiency and makes it impossible to spray multiple injection molded parts evenly.

[0005] Therefore, this utility model provides an injection molding part processing spraying device that is easy to flip, in order to solve the above problems. Utility Model Content

[0006] This invention provides a spraying device for injection molded parts that is easy to flip, aiming to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a spraying device for injection molded parts that is easy to flip, comprising a spraying tank, wherein a sealing cover is provided on the top of the spraying tank, and a lifting cylinder is connected to both sides below the sealing cover, wherein the lifting cylinder is fixedly connected to the outer wall of the spraying tank.

[0008] A flipping assembly includes a servo motor, which is fixedly connected to the bottom of the spray can.

A suspension assembly is disposed above the flip plate and is used for hanging small injection molded parts.

[0009] As a preferred technical solution of this application, the outer surface of the spray can is integrally formed with an air extraction pipe, and the inner wall of the spray can is fixedly connected with a guide ring, and the inner wall of the guide ring is evenly distributed with nozzles. The outer wall of the guide ring is integrally formed with a connecting pipe, and the connecting pipe extends to the outside of the spray can.

[0010] As a preferred technical solution of this application, the end of the extraction pipe is connected to an external extraction device, and the end of the connecting pipe is connected to an external paint supply pipe.

[0011] As a preferred technical solution of this application, a support plate and a first gear are fixedly connected to the outer wall of the spindle, and a second gear is meshed with the outside of the first gear, and a gear ring is meshed with the outside of the second gear.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-5 As shown, this utility model provides a spraying device for easy flipping of injection molded parts, including a spraying tank 1, a sealing cover 15 on the top of the spraying tank 1, and lifting cylinders 16 connected to the lower sides of both sides of the sealing cover 15, the lifting cylinders 16 being fixedly connected to the outer wall of the spraying tank 1; a flipping assembly 2, which includes a servo motor 21, which is fixedly connected to the bottom of the spraying tank 1, the output end of the servo motor 21 being connected to a main shaft 22, and the main shaft 22 rotatably penetrating into the interior of the spraying tank 1, the top of the main shaft 22 being fixedly connected to a flipping plate 29; and a suspension assembly 3, which is set above the flipping plate 29 and is used for hanging small injection molded parts. Through the setting of the flipping assembly 2, the flipping plate 29 can revolve around the sun while driving the suspension assembly 3 to rotate, thereby ensuring the uniformity of the surface spraying when the injection molded parts hanging outside the suspension assembly 3 rotate inside the spraying tank 1.

[0021] Furthermore, the exterior of the spray tank 1 is integrally formed with an extraction pipe 11, and the inner wall of the spray tank 1 is fixedly connected with a guide ring 13. The inner wall of the guide ring 13 is evenly distributed with nozzles 14. The outer wall of the guide ring 13 is integrally formed with a connecting pipe 12, which extends to the exterior of the spray tank 1. The end of the extraction pipe 11 is connected to an external extraction device, and the end of the connecting pipe 12 is connected to an external paint supply pipe. By supplying paint to the guide ring 13, the paint is sprayed out through the nozzles 14, thus performing surface spraying on the injection molded parts inside the spray tank 1. At the same time, the extraction pipe 11, in conjunction with the external extraction device, extracts and recovers excess paint.

[0022] Furthermore, a support plate 23 and a first gear 24 are fixedly connected to the outer wall of the main shaft 22, and a second gear 25 is meshed with the outer side of the first gear 24, and a gear ring 27 is meshed with the outer side of the second gear 25. A support column 26 is fixedly connected to the upper surface of the second gear 25, and the support column 26 is used for the installation and fixation of the suspension assembly 3. A positioning shaft is rotatably connected to the center of the second gear 25, and the positioning shaft is fixedly connected to the upper surface of the support plate 23. A positioning ring 28 is fixedly connected to the outer wall of the gear ring 27, and the positioning ring 28 is fixedly connected to the inner wall of the spray can 1. When the main shaft 22 rotates, it can drive the support plate 23 and the first gear 24 to rotate. When the first gear 24 rotates, it drives the second gear 25 to rotate, thereby causing the support column 26 above the second gear 25 to drive the suspension assembly 3 to rotate.

[0023] Furthermore, a limiting ring is provided at the bottom of the support plate 23, and the limiting ring is sealed and sleeved on the outer wall of the positioning ring 28. The lower surface of the support plate 23 is rotatably attached to the upper surface of the positioning ring 28. Through the sealed rotatable connection between the support plate 23 and the positioning ring 28, the paint is prevented from entering the interior of the support plate 23 and contacting the first gear 24 or the second gear 25, thereby improving the stability of the gear transmission.

[0024] Furthermore, the suspension assembly 3 includes a threaded cylinder 31, which is threadedly connected to the top of the support column 26. The threaded cylinder 31 is internally threaded with a threaded rod 32, and a hook 33 is fixedly connected to the top of the threaded rod 32. Through the threaded connection between the threaded cylinder 31 and the threaded rod 32, the connection height between the threaded cylinder 31 and the threaded rod 32 can be adjusted, thereby adjusting the height of the hook 33. This allows for the adjustment of the height of the suspended injection molded part, preventing partial obstruction of the injection molded part at the same height.

[0025] Working principle: First, the lifting cylinder 16 is controlled to lift the sealing cover 15, so that the suspension component 3 can be installed and adjusted inside the spray tank 1. Then, the injection molded part is suspended outside the hook 33. The sealing cover 15 is then lowered to seal the spray tank 1. At this time, the paint is sprayed inside the spray tank 1 through the nozzle 14. At the same time, the servo motor 21 is started. When the servo motor 21 is working, it drives the main shaft 22 to rotate. Furthermore, through the meshing of the first gear 24, the second gear 25 and the gear ring 27, the second gear 25 drives the support column 26 to rotate, so as to realize the rotation of the suspension component 3, thereby ensuring the uniformity of the spraying on the surface of the injection molded part. If the spraying process of large injection molded parts is to be realized, the suspension component 3 can be removed and a large injection molded part can be placed on top of the flip plate 29.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
