Description

Technical Field

[0001] This utility model relates to the field of rubber product processing technology, specifically to a rubber product surface spraying device. Background Technology

[0002] Patent publication number CN213727349U relates to a rubber product surface spraying machine, which achieves a reasonable spraying effect by coordinating the spraying device and rubber parts through a relatively regular spraying mechanism, thereby improving product quality and reliability. It includes a paint tank, a paint pipe, and a pressure nozzle, with the other end of the paint pipe connected to the top input end of the pressure nozzle. It also includes a spraying frame, a transmission shaft, a transmission roller, a transmission motor, a reducer, a mounting block, a slotted frame, a slider, a controller, a button, and a transmission box. The paint tank is located in the middle of the bottom of the spraying frame. The upper middle side of the left end of the spraying frame is connected to the right end of the reducer. The top output end of the reducer is connected to the bottom input end of the transmission motor. The pressure nozzle is mounted and fixed on the slider with the nozzle facing downwards. The rear left side of the top of the spraying frame is connected to the bottom of the controller. The controller output end is connected to the control system. The right side of the top of the controller is connected to the inner end of the button.

[0003] Existing technologies cannot adjust the spraying rate of the nozzle when spraying rubber products, meaning they cannot adjust the concentration of the sprayed coating. This makes it difficult to achieve the required coating thickness on the surface of rubber products when facing different spraying needs, and it also affects the uniformity of the coating on the surface of rubber products, thus reducing the production quality of the products. Utility Model Content

[0004] The purpose of this invention is to provide a device for spraying rubber products.

[0005] The technical problem solved by this utility model is: to adjust the concentration of the spray coating according to different spraying requirements so that the spraying thickness on the surface of rubber products meets the standard, thereby improving the uniformity of the coating.

[0006] This utility model can be achieved through the following technical solution: it includes a water collection tank and a support frame fixedly installed on its top. A placement frame is slidably installed on the top of the water collection tank. A rack plate is slidably installed on both sides of the support frame. A linkage mechanism is installed between the rack plate and the placement frame to cause the two to move alternately. A spraying mechanism is installed on the support frame. The spraying mechanism includes a radiation nozzle fixedly connected to the bottom of the top plate of the support frame. A hollow sphere is provided inside the radiation nozzle and is rotatably connected to the radiation nozzle through a rotating rod.

[0007] A further technical improvement of this utility model is that the working surface at the bottom of the radiation nozzle is set as a spherical surface, and the holes at the bottom of the radiation nozzle are the same size and corresponding in position as the holes on the surface of the hollow sphere, so that the holes on the radiation nozzle and the holes on the hollow sphere can be aligned or staggered by adjusting the rotating rod.

[0008] Furthermore, the connection between the rotating rod and the radiation nozzle is sealed to prevent paint leakage.

[0009] Furthermore, the linkage mechanism includes a first rotating plate rotatably connected to one side of the water collection tank, a first push-pull plate rotatably connected to the end of the first rotating plate, a synchronization plate rotatably connected to the end of the first push-pull plate away from the first rotating plate, connecting plates rotatably connected to both ends of the synchronization plate, the bottom end of the connecting plate rotatably connected to one side of the placement frame, and the top end of the connecting plate slidably connected to the rack plate through a support plate.

[0010] Furthermore, the four endpoints of the two connecting plates are always kept at the same position as the four endpoints of the same parallelogram, so that the rack plate maintains a stable motion under the action of the two connecting plates.

[0011] Furthermore, the spraying mechanism also includes a storage tank fixedly connected to the top of the support frame, a piston cylinder fixedly installed on the top of the support frame, a one-way feed valve fixedly connected between the piston cylinder and the storage tank, a piston rod slidably installed through the top of the piston cylinder, and an extrusion plate fixedly connected to the top of the piston rod.

[0012] Furthermore, gears are provided on both sides of the top of the support frame through rods that are rotatably connected to the support frame. The gears mesh with the rack plate. A second rotating plate is fixedly installed on the other end of the rod on the gear. A second push-pull plate is rotatably connected to the end of the second rotating plate away from the rod. The end of the second push-pull plate away from the second rotating plate is rotatably connected to one side of the extrusion plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This application adjusts the overlap between the holes on the surface of the hollow sphere and the holes on the bottom of the radiation nozzle, thereby adjusting the rate at which the radiation nozzle sprays the coating, thus changing the coating thickness of the coating sprayed onto the surface of the rubber product to meet the requirements of different coating thicknesses for different rubber products and improving the uniformity of the coating.

[0015] 2. Under the rotation of the first rotating rod, the placement frame and the rack plate reciprocate alternately, thereby causing the placement frame to reciprocate at the bottom of the radiation nozzle and causing the radiation nozzle to continuously spray the coating material, thereby enabling the coating material to be evenly sprayed on the surface of the rubber product.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figure 1-3 As shown, this embodiment provides a rubber product surface spraying device, including a water collection tank 1, which stores clean water for collecting excess paint sprayed during the spraying process. A support frame 2 is fixedly connected to the top of the water collection tank 1, and a placement frame 3 is slidably connected to the top of the water collection tank 1. A storage tank 4 is fixedly installed on the top of the support frame 2, and a piston cylinder 5 is fixedly installed on the top of the support frame 2 near the storage tank 4. A one-way feed valve 6 is fixedly connected between the piston cylinder 5 and the storage tank 4. The one-way feed valve 6 ensures that the liquid can only flow from the storage tank 4 into the piston cylinder 5, and cannot flow from the piston cylinder 5 into the storage tank 4.

[0023] Both sides of the support frame 2 are slidably connected to rack plates 7. The side of the rack plate 7 away from the support frame 2 is fixedly connected to a support plate 8. Both sides of the placement frame 3 are provided with a pair of connecting plates 9. The bottom end of the connecting plate 9 is rotatably connected to one side of the placement frame 3, and the top end of the connecting plate 9 is slidably connected to the support plate 8. One side of each pair of connecting plates 9 is rotatably connected to both ends of the synchronization plate 10. The center of the synchronization plate 10 is rotatably connected to a first push-pull plate 11. The end of the first push-pull plate 11 away from the synchronization plate 10 is rotatably connected to a first rotating plate 12. The end of the first rotating plate 12 away from the first push-pull plate 11 is rotatably connected to one side of the water collection tank 1. The water collection tank 1 is equipped with a drive motor (not shown in the figure) that drives the first rotating plate 12 to rotate.

[0024] The top two sides of the support frame 2 are provided with gears 13 that are rotatably connected to the support frame 2 via rods. The gears 13 mesh with the rack plate 7. A second rotating plate 14 is fixedly installed at the end of the rod away from the gears 13. A second push-pull plate 15 is rotatably connected at the end of the second rotating plate 14 away from the rotating rod 19. The ends of the two second push-pull plates 15 away from the second rotating plate 14 are rotatably connected to the two sides of the extrusion plate 16. A piston rod 17 is slidably provided through the top of the piston cylinder 5. The top of the piston rod 17 is fixedly connected to the bottom of the extrusion plate 16. The piston at the bottom of the piston rod 17 is in contact with the inner circumferential wall of the piston cylinder 5.

[0025] When the first rotating plate 12 rotates, the first push-pull plate 11 pushes and pulls the connecting plate 9 through the synchronous plate 10. At this time, the bottom end of the connecting plate 9 rotates on one side of the placement frame 3, and the top end slides on one side of the support plate 8, so that the four ends of each pair of connecting plates 9 always remain at the four ends of the parallelogram. Then, the support plate 8 drives the rack plate 7 to slide on one side of the support frame 2. During the sliding process of the rack plate 7, it drives the gear 13 that meshes with it to rotate, so that the gear 13 drives the second rotating plate 14 to rotate through the rod body, so that the second push-pull plate 15 drives the piston rod 17 to move up and down in the vertical direction through the extrusion plate 16.

[0026] The bottom of the piston cylinder 5 is fixedly connected to a radiation nozzle 18 that penetrates the top plate of the support frame 2. The working surface of the bottom of the radiation nozzle 18 is set as a spherical surface. A rotating rod 19 is rotatably connected through one side of the outer peripheral wall of the radiation nozzle 18. A hollow sphere 20 adapted to the working surface of the bottom of the radiation nozzle 18 is fixedly connected to one end of the rotating rod 19 that extends into the radiation nozzle 18. The holes opened at the bottom of the radiation nozzle 18 and the outer peripheral wall of the hollow sphere 20 are the same size and corresponding in position.

[0027] When the piston rod 17 moves upward, the liquid paint in the storage tank 4 is introduced into the piston cylinder 5 through the one-way feed valve 6. When the piston rod 17 moves downward, the liquid paint in the piston cylinder 5 is introduced into the radiation nozzle 18. By rotating the rotating rod 19, the overlap between the holes on the hollow sphere 20 and the holes on the bottom of the radiation nozzle 18 is adjusted. The greater the overlap between the holes, the lower the rate at which the radiation nozzle 18 sprays paint, and vice versa.

[0028] In use, the rubber product to be coated is placed on top of the placement rack 3. Then, the placement rack 3 and the rack plate 7 are moved back and forth alternately by the first rotating plate 12, the first push-pull plate 11, a pair of connecting plates 9, the synchronous plate 10 and the support plate 8. The rack plate 7, through the gear 13, the second rotating plate 14, the second push-pull plate 15 and the extrusion plate 16, causes the piston rod 17 to move up and down in the vertical direction, thereby continuously transporting the liquid coating in the storage cylinder to the radiation nozzle 18. By rotating the rotating rod 19, the overlap between the holes on the surface of the hollow sphere 20 and the holes on the bottom of the radiation nozzle 18 is adjusted to meet the coating thickness requirements of the rubber product surface. The coating is radially sprayed from the bottom spherical surface of the radiation nozzle 18 onto the surface of the rubber product that is moved back and forth at the bottom of the radiation nozzle 18 by the placement rack 3, so that the coating on the surface of the rubber product is uniform and of moderate thickness.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
