A multi-station synchronous paint spraying treatment device

Abstract

This invention relates to the field of spraying technology and discloses a multi-station synchronous paint spraying device, including a spraying box, multiple spray nozzles disposed within the spraying box, and a mounting plate rotatably mounted within the spraying box. The mounting plate has a cavity, and multiple mounting columns are rotatably mounted through both sides of the mounting plate. This invention utilizes an arc-shaped sealing plate slidably disposed on both sides of the mounting plate. A serrated strip, engaging with a locking tooth, is fixedly mounted on a connecting plate on one side of the arc-shaped sealing plate. After a plastic toy is clamped onto a toy model clamp located outside the spraying box, a motor is started to rotate the mounting plate. During rotation, the mounting plate moves the serrated strip. Because the serrated strip engages with the locking tooth, during movement, it causes the arc-shaped sealing plates on both sides to retract towards one side of the mounting plate, ensuring that the arc-shaped sealing plates do not extend beyond the operating table during the entire movement, thus preventing accidental injury to workers located on one side of the operating table.

Description

Technical Field

[0001] This invention relates to the field of spraying technology, specifically to a multi-station synchronous paint spraying treatment device. Background Technology

[0002] The painting process plays a crucial role in the manufacturing of products such as plastic toys. Currently, the main painting method is single-axis painting equipment. For example, the patent announcement number CN211989355U discloses a plastic surface painting device for uniform painting, which includes a box and a nozzle. The bottom of the inner surface of the box is rotatably connected to a support column through a first rotating bearing. A support plate is fixedly connected to the top of the support column. A horizontal plate is fixedly connected to the top of the support plate. The horizontal plate is a hollow structure with a sliding groove on the top. A rotating mechanism is provided on the column wall of the support column. A clamping mechanism is provided inside the horizontal plate. A horizontal bar is provided above the horizontal plate. A rack is slidably sleeved on the bar wall. A reciprocating spraying mechanism is provided above the rack. The bottom of the rack is fixedly connected to the top of the nozzle, which can perform complete and uniform painting on the plastic surface.

[0003] Current plastic toy spraying equipment consists of a spraying chamber, spray nozzles inside the chamber, and a rotating conveyor for placing the plastic toys. During spraying, workers place the toys from the workbench onto the rotating conveyor, which then transports them into the spraying chamber for spraying. Because the paint can have some impact on human health, the rotating conveyor maintains a relatively sealed environment within the spraying chamber after rotation. Simultaneously, ventilation equipment is installed on the spraying chamber. Most existing spraying equipment is single-axis spraying, as described above. In large-scale factory production, single-axis spraying affects work efficiency. To improve efficiency, multiple spraying stations are typically set up, requiring a wider rotating conveyor. During the rotation and transport process, workers at each station must maintain a certain distance to avoid accidental injury, posing a safety hazard. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-station synchronous paint spraying device that maintains relative sealing while ensuring that plastic toys do not pose a safety hazard to workers during transport.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-station synchronous paint spraying device, comprising a spraying box, multiple spray nozzles disposed within the spraying box, and a mounting plate rotatably mounted within the spraying box. A cavity is formed within the mounting plate, and multiple mounting columns are rotatably mounted through both sides of the mounting plate. Toy model clamping components are mounted on the outer sides of each of the mounting columns. A ring is fixedly mounted within the spraying box, penetrating the mounting plate and located within the cavity. Multiple locking teeth are fixedly mounted on both sides of the ring. Telescopic components that engage with the locking teeth are slidably disposed through both sides of the mounting plate. A motor controlling the rotation of the mounting plate is fixedly mounted within the spraying box. The motor operates by cooperating with the ring and locking teeth to control the extension and retraction of the telescopic components. A mounting frame is fixedly mounted within the spraying box. A pushing component controlling the rotation of the toy model clamping components is disposed within the cavity. An electric push rod controlling the movement of the pushing component is mounted on the mounting frame. A pressing component for pushing the toy model clamping components to open and close is disposed through the upper end of the mounting plate. When the motor controls the rotation of the mounting plate, it also controls the lifting and lowering of the pressing component.

[0006] Preferably, it also includes glass windows installed on the periphery and front of the spraying box, and an operating table is provided on the front of the spraying box.

[0007] Preferably, the mounting frame includes a support frame fixedly mounted on the spray box body, with a mounting base rotatably mounted on the upper end of the support frame, and the electric actuator fixedly mounted on the mounting base.

[0008] Preferably, the telescopic component includes two arc-shaped sealing plates, which respectively pass through both ends of the mounting plate and are slidably connected thereto. A connecting plate is fixedly connected to one end of the arc-shaped sealing plate inside the cavity. A return spring is fixedly provided between the connecting plate and the inner wall of the cavity. A serrated strip that meshes with the locking teeth is fixedly installed on one side of the connecting plate.

[0009] Preferably, the toy model clamping component includes a base plate fixedly installed on the outside of the mounting column, a clamping plate rotatably installed on the base plate, a toy model base fixedly installed at the outer end of the base plate, a toy model cover plate fixedly installed at the outer end of the clamping plate, and the clamping plate being rotatably connected to the base plate via a spring shaft.

[0010] Preferably, the pushing component includes a connecting rod fixedly installed at the working end of the electric push rod, and a toothed ring is fixedly sleeved at one end of each of the plurality of mounting columns located in the cavity. A sawtooth block that is slidably connected to the inner wall of the cavity is engaged on one side of each of the plurality of toothed rings. The plurality of sawtooth blocks located on the same side of the cavity are fixedly connected to each other, and the sawtooth blocks on both sides are fixedly connected to each other by a connecting rod.

[0011] Preferably, the extrusion member includes a U-shaped rod that penetrates and slidably connects to the mounting plate. A placement rod is fixedly installed between the ends of the multiple U-shaped rods located inside the cavity. A telescopic spring is fixedly installed between the placement rod and the upper wall of the cavity. An extrusion rod is fixedly installed between the ends of the multiple U-shaped rods located outside the cavity. The extrusion rod is used to push the clamping plate to rotate. An arc-shaped column is fixedly installed at the upper end of the U-shaped rod located in the middle position. An arc-shaped plate is fixedly installed on the spray box. The curvature of the arc-shaped plate is consistent with part of the movement trajectory of the arc-shaped column. The lower end of the arc-shaped plate is also arc-shaped. The upper end of the arc-shaped column slides in contact with the lower end of the arc-shaped plate.

[0012] Preferably, the mounting column is rotatably connected to the mounting plate via a damping shaft.

[0013] Preferably, the mounting plate has a connection port at its bottom, and both the ring and the mounting bracket pass through the connection port and are located inside the cavity.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention involves fixing multiple locking teeth on both sides of the inner ring of the spraying box, and sliding arc-shaped sealing plates on both sides of the mounting plate. A serrated strip that meshes with the locking teeth is fixedly installed on the connecting plate on one side of the arc-shaped sealing plate. After the plastic toy is clamped on the toy model clamping part located outside the spraying box, the motor is started to drive the mounting plate to rotate. During the rotation of the mounting plate, the serrated strip moves. Since the serrated strip meshes with the locking teeth, it will cause the arc-shaped sealing plates on both sides to retract towards one side of the mounting plate during the movement. This ensures that the arc-shaped sealing plates will not extend out of the operating table during the entire movement, thus preventing accidental injury to the workers located on one side of the operating table. When the motor transports the plastic toy to the spraying station, the serrated strip and locking teeth no longer mesh. Due to the action of the return spring, the arc-shaped sealing plate moves to seal the spraying box, forming a relatively sealed state and reducing the amount of paint that escapes with the air during spraying.

[0015] 2. In this invention, a placement rod is fixedly installed between one end of multiple U-shaped rods, and a telescopic spring is fixedly installed between the placement rod and the upper wall of the cavity. A pressing rod is fixedly installed between the other ends of the multiple U-shaped rods. An arc-shaped column is fixedly installed at the upper end of the U-shaped rod located in the middle position. The upper end of the arc-shaped column slides in contact with the lower end of the arc-shaped plate. The curvature of the arc-shaped plate is consistent with the partial movement trajectory of the arc-shaped column. When the motor controls the installation plate to rotate and moves the painted plastic toy to one side of the operating table, the arc-shaped plate will press the arc-shaped column to control one end of the clamping plate to be pressed and rotated downward, causing the toy model cover plate and the toy model base to be in an open state, making it easy to remove the painted plastic toy. The motor rotates slightly. When the arc-shaped column is separated from the arc-shaped plate, due to the action of the telescopic spring and the spring shaft, the toy model cover plate and the toy model base are in a closed state for the next painting.

[0016] 3. This invention uses toothed rings fixedly fitted at one end of multiple mounting posts, and sawtooth blocks that are slidably connected to the inner wall of the cavity are engaged on one side of each toothed ring. During spraying, the electric actuator is activated to control the movement of the sawtooth blocks, which in turn drives the toothed rings to rotate, causing the plastic toy to rotate and perform uniform spraying in multiple directions. The sawtooth blocks on both sides of the cavity are partially staggered, so that their rotation states on both sides are different. Before spraying, the toy model clamping part inside the spraying box is in an inclined state, which facilitates direct rotation for spraying without back-and-forth spraying, which may cause uneven spraying. The toy model clamping part outside the spraying box is in a horizontal state, which facilitates the removal of the toy. The motor is started and rotated slightly, and the arc plate disengages from the arc post. At this time, the electric actuator is activated to control the rotation of the toy model clamping part inside the spraying box, which performs complete spraying on the back of the toy. Afterward, the electric actuator drives the toy model clamping part to rotate back until it is in a horizontal state, which facilitates the removal and removal of the toy. At this time, the toy model clamping part outside the spraying box rotates to an inclined state, which becomes the starting point for the next spraying. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] Please see Figures 1-8 A multi-station synchronous paint spraying device includes a spraying box 1, multiple spray nozzles 31 disposed within the spraying box 1, and a mounting plate 3 rotatably mounted within the spraying box 1. It also includes glass windows 29 mounted on the periphery and front of the spraying box 1 (for easy observation of the internal spraying process). An operating platform 30 is provided on the front of the spraying box 1. A cavity 32 is formed within the mounting plate 3. Multiple mounting columns 14 are rotatably mounted through both sides of the mounting plate 3. Toy model clamping components are mounted on the outer sides of the mounting columns 14. A circular ring 7 is fixedly mounted inside the spraying box 1, penetrating the mounting plate 3 and located within the cavity 32 (a connection port is provided at the bottom of the mounting plate 3, through which the circular ring 7 passes). Inside, multiple locking teeth 17 are fixedly installed on both sides of the circular ring 7. Telescopic components that engage with the locking teeth 17 are slidably installed on both sides of the mounting plate 3. A motor 16 that controls the rotation of the mounting plate 3 is fixedly installed inside the spray box 1. The motor 16 operates by cooperating with the circular ring 7 and the locking teeth 17 to control the extension and retraction of the telescopic components. The telescopic components include two arc-shaped sealing plates 2, which respectively pass through both ends of the mounting plate 3 and are slidably connected to it. One end of the arc-shaped sealing plate 2 is fixedly connected to a connecting plate 21 inside the cavity 32. A return spring 8 is fixedly installed between the connecting plate 21 and the inner wall of the cavity 32. A serrated strip 15 that engages with the locking teeth 17 is fixedly installed on one side of the connecting plate 21. The operating table 30... After the plastic toy is clamped onto the toy model clamp located on the outside of the spray box 1, the motor 16 is started to drive the mounting plate 3 to rotate. During the rotation of the mounting plate 3, the serrated strip 15 moves. Since the serrated strip 15 is engaged with the locking teeth 17, during the movement, it will drive the connecting plates 21 on both sides to move. The return spring 8 is stretched, and the connecting plates 21 on both sides drive the arc-shaped sealing plate 2 connected to it to retract towards the mounting plate 3 side, so that the arc-shaped sealing plate 2 will not extend out of the operating table 30 during the entire movement, and will not accidentally injure the staff on the side of the operating table 30. When the motor 16 transports the plastic toy to the spraying station, the serrated strip 15 and the locking teeth 17 are not engaged. Due to the action of the return spring 8, the connecting plate 21 is pushed to move, pushing the arc-shaped sealing plate 2 to abut against the inner wall of the spray box 1, so that the spray box 1 forms a relatively sealed state, reducing the amount of paint that is released with the air during spraying. A mounting frame is fixedly installed inside the spray box 1. A pusher is provided in the cavity 32 to control the rotation of the toy model clamping parts. An electric push rod 22 is installed on the mounting frame to control the movement of the pusher. The mounting frame has a through connection port located in the cavity 32. The mounting frame includes a support frame 24 fixedly installed on the spray box 1. A mounting base 23 is rotatably installed on the upper end of the support frame 24. The electric push rod 22 is fixedly installed on the mounting base 23. An extrusion part for pushing the toy model clamping parts to open and close is provided through the upper end of the mounting plate 3. When the motor 16 controls the rotation of the mounting plate 3, it is also used to control the lifting and lowering of the extrusion part.

[0021] As a further technical solution of the present invention, the toy model clamping component includes a base plate 13 fixedly installed on the outside of the mounting column 14 (installed by bolts, detachable, and easy to replace with different toy model clamping components to adapt to different plastic toys), a clamping plate 12 rotatably installed on the base plate 13, a toy model base 28 fixedly installed on the outer end of the base plate 13, a toy model cover plate 10 fixedly installed on the outer end of the clamping plate 12, and the clamping plate 12 rotatably connected to the base plate 13 through a spring shaft 9. The extrusion component includes a U-shaped rod 6 that penetrates the mounting plate 3 and is slidably connected thereto. A placement rod 20 is fixedly installed between the ends of the multiple U-shaped rods 6 located inside the cavity 32. A telescopic spring 27 is fixedly provided between the placement rod 20 and the upper wall of the cavity 32. An extrusion rod 11 is fixedly installed between the ends of the multiple U-shaped rods 6 located outside the cavity 32. The extrusion rod 11 is used to push the clamping plate 12 to rotate. An arc-shaped column is fixedly installed on the upper end of the U-shaped rod 6 located in the middle position. 4. An arc-shaped plate 5 is fixedly installed on the spray box 1. The curvature of the arc-shaped plate 5 is consistent with the partial movement trajectory of the arc-shaped column 4. The lower end of the arc-shaped plate 5 is also arc-shaped. The upper end of the arc-shaped column 4 slides in contact with the lower end of the arc-shaped plate 5. When the motor 16 controls the installation plate 3 to rotate and moves the plastic toy that has finished spraying to one side of the operating table 30, the arc-shaped plate 5 will squeeze the arc-shaped column 4. During this process, one end of the control clamp 12 will be squeezed and rotated downward, causing the toy model cover plate 10 and the toy model base 28 to be in an open state, making it easy to remove the sprayed plastic toy. Then the motor 16 rotates slightly. When the arc-shaped column 4 is separated from the arc-shaped plate 5 (at this time, the positions of the toy model cover plate 10, the toy model base 28 and the spray nozzle 31 in the spray box 1 correspond one-to-one), due to the action of the telescopic spring 27 and the spring shaft 9, the toy model cover plate 10 and the toy model base 28 are in a closed state for the next spraying.

[0022] As a further technical solution of the present invention, the pushing component includes a connecting rod 25 fixedly installed at the working end of the electric push rod 22. Multiple mounting posts 14 are located inside the cavity 32, each with a toothed ring 19 fixedly sleeved at one end. Each toothed ring 19 has a serrated block 26 meshing with and slidingly connected to the inner wall of the cavity 32 on one side. Multiple serrated blocks 26 located on the same side of the cavity 32 are fixedly connected. The serrated blocks 26 on both sides are fixedly connected via the connecting rod 25. During spraying, the electric push rod 22 is activated, pushing the connecting rod 25 to move. The connecting rod 25 pushes the multiple serrated blocks 26 to move, causing the toothed rings 19 to rotate, thus rotating the plastic toy for multi-directional and uniform spraying. The serrated blocks 26 on both sides of the cavity 32 are partially misaligned, resulting in different rotation states on both sides (see...). Figure 8 Before spraying, the toy model clamping component inside the spraying box 1 is tilted, making it easy to rotate and spray directly without having to rotate back and forth (if it rotates from horizontal to left and then to right, it will result in uneven spraying). The toy model clamping component outside the spraying box 1 is horizontal, making it easy to pick up the toy. The motor 16 is started and rotated slightly, and the arc plate 5 is disengaged from the arc column 4. At this time, the electric push rod 22 is started to control the rotation of the toy model clamping component inside the spraying box 1 to spray the back of the toy completely. After that, the electric push rod 22 drives the toy model clamping component to rotate back until it is horizontal, making it easy to remove and pick up the toy. At this time, the toy model clamping component outside the spraying box 1 is tilted, which becomes the starting point for the next spraying.

[0023] As a further technical solution of the present invention, the mounting column 14 is rotatably connected to the mounting plate 3 through the damping shaft 18, and the mounting column 14 will rotate when an external force pushes it.

[0024] In use: At this time, the arc plate 5 does not limit the arc column 4 (the arc column 4 and the arc plate 5 are in a state of just being separated). At this time, the positions of the toy model cover plate 10, the toy model base 28 and the spray nozzle 31 inside the spray box 1 correspond one-to-one. Start the electric actuator 22 to operate, and simultaneously start the spraying equipment, pushing the connecting rod 25 to move. The connecting rod 25 pushes multiple sawtooth blocks 26 to move, and the sawtooth blocks 26 drive the toothed ring 19 to rotate, causing the plastic toy to rotate (see...). Figure 8 Before spraying, the toy model clamping parts inside the spraying box 1 are in an inclined state and do not need to be rotated back and forth for spraying. If they are rotated from a horizontal state to the left and then to the right, it will result in uneven spraying. Spraying is carried out evenly in multiple directions. After spraying is completed, the spraying equipment is turned off and started. At this time, the electric push rod 22 is started to control the toy model clamping parts inside the spraying box 1 to rotate to a horizontal state (to facilitate the subsequent handling of toys). At this time, the toy model clamping parts outside the spraying box 1 are finally in an inclined state, which becomes the starting point for the next spraying. Then, the motor 16 is started to drive the mounting plate 3 to rotate. During the rotation of the mounting plate 3, the serrated strip 15 moves. Since the serrated strip 15 is engaged with the locking teeth 17, during the movement, it will drive the connecting plates 21 on both sides to move. The return spring 8 is stretched, and the connecting plates 21 on both sides drive the arc-shaped sealing plate 2 connected to it to retract towards the mounting plate 3. This ensures that the arc-shaped sealing plate 2 will not extend out of the operating table 30 during the entire movement process, and will not accidentally injure the staff located on one side of the operating table 30. When the motor 16 transports the plastic toy to the spraying station, the serrated strip 15 and the locking teeth 17 are no longer engaged. Due to the action of the return spring 8, the connecting plate 21 is pushed to move, pushing the arc-shaped sealing plate 2 to abut against the inner wall of the spraying box 1, so that the spraying box 1 forms a relatively sealed state, reducing the amount of paint that is released with the air during spraying. When the motor 16 operates and the control mounting plate 3 rotates, the plastic toy that has finished painting is moved to one side of the operating table 30. During this process, the arc-shaped plate 5 will squeeze the arc-shaped column 4. The squeezing of the arc-shaped column 4 pushes the U-shaped rod 6 down, and the U-shaped rod 6 pushes the squeezing rod 11 down. The telescopic spring 27 is stretched, and the squeezing rod 11 squeezes one end of the clamping plate 12 to make it rotate, causing the toy model cover plate 10 and the toy model base 28 to be in an open state, making it easy to remove the painted plastic toy. Then, the toy to be painted is placed on the toy model base 28 (here). Note that the toy model base 28 and toy model cover 10 need to be matched and set according to the specific toy model (the attached diagram of this application only shows a set of clamping plates). Then, the control motor 16 rotates slightly. When the arc-shaped column 4 is disengaged from the arc-shaped plate 5 (at this time, the positions of the toy model cover 10, toy model base 28 and spray nozzle 31 in the spray box 1 correspond one-to-one), due to the action of the telescopic spring 27 and the spring shaft 9, the toy model cover 10 and toy model base 28 are in a closed state for the next spraying.

[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will readily make equivalent substitutions for its features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
