Description

Technical Field

[0001] This utility model relates to the field of painting technology for steel lockers, specifically a painting device for the production of steel lockers. Background Technology

[0002] Mobile electrostatic spraying machines are commonly used in the production of steel lockers. They combine the high efficiency of electrostatic spraying with the flexibility of mobile operation, making them particularly suitable for spraying irregularly shaped parts of lockers in small to medium-sized production scenarios. Their working principle involves using an electrostatic generator to charge paint particles, which then quickly adhere to the surface of the steel workpiece through electrostatic adsorption. This results in a uniform coating with strong adhesion, meeting the locker's requirements for corrosion resistance and appearance. Furthermore, the high paint mist utilization rate (up to 80% or more) makes them more energy-efficient and environmentally friendly. For larger workpieces like steel lockers, mobile electrostatic spraying machines, with their built-in wheels or pushable design, can directly approach the workpiece for operation, eliminating the need to frequently move the bulky cabinet. This significantly reduces labor costs and operational difficulty. They can flexibly approach locker components at different workstations, such as cabinet corners and door panel recesses, overcoming the limitations of fixed spray lines in handling complex structures. Therefore, they are an important and practical spraying device in the production of steel lockers.

[0003] However, existing mobile electrostatic spraying machines rely on casters for support when moving steel storage cabinets, and the feed cylinder is not well stabilized on the base, resulting in poor overall stability. During movement, the feed cylinder is prone to shaking and shifting, and even slight unevenness on the ground may cause it to tip over and slip, increasing operational risks. Utility Model Content

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1 Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a painting device for the production of steel lockers, including a base 1, a painting machine body 2, a feeding cylinder 3, a spray gun 4 and casters 15. The painting machine body 2 is fixedly connected to the upper front end of the base 1. The feeding cylinder 3 is set on the upper surface of the base 1 and is movably connected to the base 1. The spray gun 4 is set on the upper right side of the painting machine body 2 and is fixedly connected to the feeding cylinder 3 through a pipe. There are four casters 15, which are fixedly connected to the four corners of the lower surface of the base 1. The base 1 has a cavity inside. The upper surface of the base 1 has movable grooves 5 on the left and right sides respectively. The base 1 has a stabilizing device 6 inside. The stabilizing device 6 includes support rods 7, clamping components 8, and control mechanism 9. There are two support rods 7, which are respectively located on the front and rear sides inside the base 1, and the left and right ends are respectively fixedly connected to the left and right sides of the inside of the base 1. There are two clamping components 8, which are respectively located on the left and right sides of the upper part inside the base 1. The control mechanism 9 is located at the lower part inside the base 1.

[0022] Specifically, the stabilizing device 6 reliably fixes the feeding cylinder 3, effectively preventing the feeding cylinder 3 from shaking or shifting during movement, thus improving the overall stability and operational safety of the equipment.

[0023] Furthermore, in the stabilizing device 6, the control mechanism 9 drives the clamping component 8 to slide along the support rod 7, so that the arc-shaped clamping plate 82 forms a ring-shaped clamping on the feed cylinder 3. All components work together to stabilize and release the feed cylinder 3, ensuring the smooth progress of the painting operation.

[0024] Example 2 In the second embodiment of this utility model, the clamping assembly 8 includes a movable seat 81, an arc-shaped clamping plate 82, a pull rod 83, and an elastic sealing gasket 84. The movable seat 81 is sleeved on the right end surface of the two support rods 7 and is slidably connected to the support rods 7. The upper end of the movable seat 81 extends out of the base 1 through the movable groove 5 and is movably connected to the base 1. The arc-shaped clamping plate 82 is fixedly connected to the upper end of the movable seat 81 and corresponds to and is adapted to the feeding cylinder 3. There are two pull rods 83, which are fixedly connected to the left and right sides of the lower surface of the movable seat 81, respectively. The elastic sealing gasket 84 is disposed inside the movable groove 5 and is fixedly connected to the inner wall of the movable groove 5. The elastic sealing gasket 84 is sleeved on the upper end of the movable seat 81 and is fixedly connected to the movable seat 81. Rubber anti-slip pads 10 are fixedly connected to the surfaces of the two arc-shaped clamping plates 82 that are close to each other.

[0025] Specifically, by setting the clamping component 8, a stable ring-shaped clamping can be formed on the feeding cylinder 3, which effectively prevents the feeding cylinder 3 from shaking or shifting when the equipment moves or during the painting operation, thus ensuring the stability of the paint supply during the painting process.

[0026] Furthermore, the movement of the rotating seat 911 will generate a pulling force on the connecting rod 912, and at the same time cause the connecting rod 912 to rotate around the pull rod 83, transmitting the pulling force to the pull rod 83, which in turn pulls the movable seat 81 sleeved on the front and rear support rods 7 to slide inward along the axis of the support rods 7. The upper end of the movable seat 81 extends through the movable groove 5 to the top of the base 1, driving the arc-shaped clamping plate 82 fixed at its top to move towards the feeding cylinder 3 simultaneously. Because the inner side of the arc-shaped clamping plate 82 is fixed with a rubber anti-slip pad 10, as... As the movable seat 81 continues to slide, the rubber anti-slip pad 10 gradually contacts and tightly adheres to the outer wall of the feeding cylinder 3. The symmetrical clamping forces on both sides form a ring-shaped clamping and fixing of the feeding cylinder 3. At the same time, when the movable seat 81 slides in the movable groove 5, the elastic sealing pad 84 sleeved on its surface is always in close contact with the inner wall of the movable groove 5. Through elastic deformation, it fills the gap and effectively prevents paint mist and dust from entering the placement cavity inside the base 1, avoiding contamination of transmission components such as the screw 921 and connecting rod 912.

[0027] Example 3 In the third embodiment of this utility model, the control mechanism 9 includes a linkage component 91 and a driving component 92. There are two linkage components 91, which are respectively arranged on the front and rear sides of the lower end of the base 1 and correspond to the positions of the pull rods 83 on both sides. The driving component 92 is arranged in the middle of the lower end of the base 1. The driving component 92 includes a screw 921, a motor 922, and a protective shell 923. The screw 921 is located in the middle of the lower end inside the base 1 and corresponds to the positions of the two pull rods 83. Both the front and rear ends of the screw 921 are rotatably connected to the base 1, and the rear end extends out of the base 1. The motor 922 is fixedly connected to the rear end of the screw 921 and is fixedly connected to the rear surface of the base 1. The protective shell 923 is fitted on the surface of the motor 922 and is fixedly connected to the rear surface of the base 1. The linkage assembly 91 includes a rotating seat 911, a connecting rod 912, and a limiting slider 913. The rotating seat 911 is sleeved on the surface of the screw 921 and is threadedly connected to the screw 921. There are two connecting rods 912, which are close to each other and are respectively sleeved on the left and right sides of the rotating seat 911 and are rotatably connected to the rotating seat 911. The ends of the two connecting rods 912 that are far apart from each other are inclined to the rear and are respectively sleeved on the surface of the pull rods 83 on the left and right sides and are rotatably connected to the pull rods 83. The limiting slider 913 is fixedly connected to the lower surface of the rotating seat 911. A limiting groove 11 is provided on the lower inner surface of the base 1. The lower ends of the two limiting sliders 913 are both set inside the limiting groove 11 and are slidably connected to the limiting groove 11.

[0028] Specifically, by setting up the control mechanism 9, the clamping component 8 can be precisely driven to achieve stable clamping and rapid release of the feeding cylinder 3, thereby improving the convenience and reliability of the fixed operation of the feeding cylinder 3.

[0029] Furthermore, the feeding cylinder 3 is placed between two arc-shaped clamping plates 82 on the base 1. Then, the motor 922 drives the screw 921 to rotate clockwise. The two rotating seats 911, which are threadedly connected to the screw 921, move away from each other along the axial direction of the screw 921. The limiting slider 913 on its lower surface slides synchronously along the limiting groove 11 inside the base 1 to ensure that the rotating seats 911 move smoothly and without deviation. When the two rotating seats 911 move away from each other along the axial direction of the screw 921, the connecting rods 912 rotatably connected on the left and right sides rotate synchronously with the displacement of the rotating seats 911. The end of the connecting rod 912 away from the rotating seats 911 tilts backward and is rotatably connected to the pull rod 83. The movement of the rotating seats 911 will generate a pulling force on the connecting rod 912, and at the same time make the connecting rod 912 rotate around the pull rod 83, transmitting the pulling force to the pull rod 83, thereby pulling the movable seat 81 sleeved on the front and rear support rods 7 to slide inward along the axial direction of the support rods 7.

[0030] Working principle: When stabilizing the feeding cylinder 3, the feeding cylinder 3 is placed between the two arc-shaped clamping plates 82 on the base 1. Then, the motor 922 drives the screw 921 to rotate clockwise. The two rotating seats 911, which are threaded to the screw 921, move away from each other along the axial direction of the screw 921. The limiting slider 913 on its lower surface slides synchronously along the limiting groove 11 inside the base 1 to ensure that the rotating seats 911 move smoothly and without deviation. When the two rotating seats 911 move away from each other along the axial direction of the screw 921, the connecting rods 912 rotatably connected on the left and right sides rotate synchronously with the displacement of the rotating seats 911. The end of the connecting rod 912 away from the rotating seats 911 tilts backward and rotatably connects to the pull rod 83. The movement of the rotating seats 911 will generate a pulling force on the connecting rod 912, and at the same time, make the connecting rod 912 rotate around the pull rod 83, transmitting the pulling force to the pull rod. 83, which in turn pulls the movable seat 81, which is sleeved on the front and rear support rods 7, to slide inward along the axis of the support rods 7. The upper end of the movable seat 81 extends through the movable groove 5 to the top of the base 1, and drives the arc-shaped clamping plate 82 fixed at its top to move closer to the feeding cylinder 3. Because the inner side of the arc-shaped clamping plate 82 is fixed with a rubber anti-slip pad 10, as the movable seat 81 continues to slide, the rubber anti-slip pad 10 gradually contacts and tightly fits the outer wall of the feeding cylinder 3. The symmetrical clamping force on both sides forms a ring-shaped clamping and fixing of the feeding cylinder 3. At the same time, when the movable seat 81 slides in the movable groove 5, the elastic sealing pad 84 sleeved on its surface always keeps in close contact with the inner wall of the movable groove 5. Through elastic deformation, it fills the gap and effectively prevents paint mist and dust from entering the placement cavity inside the base 1, avoiding contamination of transmission components such as the screw 921 and the connecting rod 912. During the subsequent release of the fixation, the control motor 922 drives the screw 921 to rotate counterclockwise. The two rotating seats 911, which are threadedly connected to the screw 921, move closer to each other along the axial direction of the screw 921. The limiting slider 913 on its lower surface slides synchronously along the limiting groove 11 to maintain stability. During the process of the rotating seats 911 moving closer, the connecting rods 912 on the left and right sides rotate synchronously in the opposite direction with the displacement of the rotating seats 911. The end of the connecting rod 912 away from the rotating seats 911 gradually unfolds, generating an outward pushing force on the pull rod 83, forcing the movable seat 81 sleeved on the support rod 7 to slide outward along the axial direction of the support rod 7. The movable seat 81 drives the arc-shaped clamping plate 82 at the top to move away from the feeding cylinder 3 synchronously, so that the rubber anti-slip pad 10 separates from the outer wall of the feeding cylinder 3, releasing the ring-shaped clamping.

[0031] In summary, by using the base 1, paint spraying machine body 2, feed cylinder 3, spray gun 4, casters 15, movable groove 5, stabilizing device 6, support rod 7, clamping assembly 8, moving seat 81, arc-shaped clamping plate 82, pull rod 83, elastic sealing gasket 84, control mechanism 9, linkage assembly 91, rotating seat 911, connecting rod 912, limit slider 913, driving component 92, screw 921, motor 922, protective shell 923, rubber anti-slip pad 10, and limit groove 11 in combination, the feed cylinder 3 is stably fixed, improving the stability of the equipment during movement and operation.
