Description

Technical Field

[0001] The utility model relates to the technical field of gas cylinder paint spraying devices, in particular to a fast and uniform paint spraying device for steel gas cylinders. Background Art

[0002] In order to maintain the anti-corrosion and anti-rust effects of the outer surface of steel gas cylinders, the outer curved surface of the gas cylinders needs to be sprayed with anti-corrosion paint or anti-rust paint during the production and processing of the gas cylinders.

[0003] An existing Chinese patent (publication number: CN219943296U) discloses a device for rapidly spraying paint on the outer curved surface of a steel gas cylinder. The device comprises a base box, the upper surface of which is fixedly connected to two corresponding support columns, the tops of the two support columns being fixedly connected to a mounting bracket, the lower surface of the mounting bracket being fixedly mounted to a shunt pipe, the surface of which is mounted with two electromagnetic switch valves, and the inner surface of the base box being fixedly connected to two symmetrically positioned bar-shaped fixing blocks. The utility model provides a limiting support wheel, a drive motor, and a limiting sleeve. When spraying paint on the surface of a steel gas cylinder, the gas cylinder can be placed on the surface of the limiting support wheel, and the limiting sleeve is used to limit and fix the head of the gas cylinder. The drive motor is then used to drive the gas cylinder to rotate on the surface of the limiting support wheel. Multiple spray heads arranged in a linear array are then used to quickly and evenly spray paint on the surface of the gas cylinder, achieving a rapid painting effect and greatly improving the efficiency of painting.

[0004] During the process of painting the steel cylinder, the above-mentioned equipment first drives the steel cylinder to rotate around its axis, and then uses multiple paint spray heads in a linear array to quickly and evenly spray paint on the surface of the cylinder. Although it can improve the efficiency of painting, different batches of steel cylinders may have differences in size. Therefore, the fixed spray heads may not be able to adapt to different batches of steel cylinders. However, during the painting process, the junction between the two spray heads often has thick paint due to the joint action of the two spray heads, which easily affects the uniformity of the paint.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-4The utility model provides a technical solution: a device for quickly and evenly spraying paint on steel gas cylinders.

[0033] comprising a base 1;

[0034] The adjusting shaft 201 is rotatably connected to the base 1. A plurality of chutes are provided on the adjusting shaft 201. The plurality of chutes are symmetrically arranged with the center perpendicular to the adjusting shaft 201 as the center.

[0035] The servo motor 202 is connected to one side of the base 1 and is used to drive the adjustment shaft 201 to rotate;

[0036] Multiple paint spray heads 203, whose positions correspond to the slide slots, move away from or closer to each other at equal intervals as the adjustment shaft 201 rotates;

[0037] Multiple wiping heads 204 are set on one side of the cylinder. Each wiping head 204 is located between two paint spraying heads 203 and is used to wipe thick paint. When the position of the paint spraying head 203 is adjusted, the wiping head 204 is adjusted synchronously.

[0038] A synchronous adjustment component 300 is provided in the base 1 for driving the wiping head 204 and the paint spraying head 203 to adjust synchronously.

[0039] During implementation, the servo motor 202 is activated, driving the adjustment shaft 201 to rotate within the base 1. As the adjustment shaft 201 rotates, the chute causes the paint spray heads 203 to move evenly apart or closer to accommodate cylinders of varying lengths. This allows for optimal painting results based on the size of steel cylinders. Multiple wiper heads 204 are positioned on one side of the cylinder, each located between two paint spray heads 203. When the positions of the paint spray heads 203 are adjusted, the synchronous adjustment assembly 300 within the base 1 drives the wiper heads 204 to adjust synchronously with the paint spray heads 203. During the painting process, the paint spray heads 203 apply paint to the cylinder surface. Because the junction between the two paint spray heads 203 may result in excessive paint buildup, the wiper head 204 located between the two paint spray heads 203 comes into play, wiping any excess paint and ensuring uniform paint application on the cylinder surface.

[0040] See Figures 1 to 3 , the synchronization adjustment component 300 includes,

[0041] The driving gear 301 is rotatably arranged on one side of the base 1 and is coaxially arranged with the adjustment shaft 201;

[0042] A driven rack 302 is meshedly connected to one side of the driving gear 301, and a transmission frame 303 is connected to the top of the driven rack 302;

[0043] A guide rod 305 is connected to the base 1, and a plurality of sliders 306 are provided on the guide rod 305 for sliding. A driven rod 307 is connected to the slider 306. A driving plate 304 is vertically slidably connected to the base 1. The top of the driving plate 304 is interconnected with the transmission frame 303. A driven rod 307 is connected to one side of the slider 306. The driven rod 307 is slidably connected to the driving plate 304. A plurality of sliding grooves that are compatible with the driven rod 307 are opened on the driving plate 304, and the sliding grooves are inclined.

[0044] Preferably, one side of the slider 306 is connected to an electric telescopic rod 8 , and the telescopic end of the electric telescopic rod 8 is connected to the wiping head 204 for further adjusting the position of the wiping head 204 .

[0045] It should be noted that the base 1 is internally connected to a driving assembly that drives the cylinder to rotate. Its specific structure can be referred to the existing patent (publication number: CN219943296U, a rapid painting device for the outer curved surface of a steel gas cylinder). This is existing technology, so no further explanation will be given here.

[0046] In specific implementations, when the servo motor 202 drives the adjustment shaft 201 to rotate, the drive gear 301, which is coaxial with the adjustment shaft 201, also rotates. The rotation of the drive gear 301 drives the driven rack 302 engaged with it to move. The transmission frame 303 connected to the top of the driven rack 302 also moves accordingly.

[0047] The transmission frame 303 is connected to the top of the driving plate 304 which is vertically slidably connected to the base 1. The movement of the transmission frame 303 drives the driving plate 304 to slide vertically on the base 1. When the driving plate 304 slides vertically, the driven rod 307 is driven to slide in the sliding groove due to the inclined arrangement of the sliding groove, thereby causing the slider 306 to slide on the guide rod 305.

[0048] The slider 306 is connected to the spray head 203 and the wiping head 204. The sliding of the slider 306 causes the spray head 203 and the wiping head 204 to move synchronously. Thus, the coordinated action of the drive gear 301, the driven rack 302, the transmission frame 303, the drive plate 304, the guide rod 305, the slider 306, and the driven rod 307 enables synchronous adjustment of the spray head 203 and the wiping head 204.

[0049] See Figure 3 A material storage box is provided in the base 1, and a delivery pump 4 for delivering paint in the material storage box is connected to one side of the base 1. The output end of the delivery pump 4 is connected to a delivery pipe 5, and a plurality of diversion pipes 6 are connected to the delivery pipe 5. The other end of the diversion pipe 6 is interconnected with the paint spray head 203.

[0050] During specific implementation, the provided material storage box facilitates the supply of paint to the paint spray head 203 , and the provided delivery pump 4 is used to deliver the paint.

[0051] refer to Figures 1 to 4 A shorting rod is slidably connected in the slide groove, and the bottom of the shorting rod is connected to the top of the paint spray head 203.

[0052] During specific implementation, this arrangement facilitates the installation of the paint spray head 203 .

[0053] refer to Figure 1 The drive shaft of the drive gear 301 is connected to a differential 9 for adjusting the speed of the drive gear 301 .

[0054] In specific implementation, this setting facilitates further ensuring that the spray head 203 and the wiping head 204 are adjusted synchronously in frequency.

[0055] refer to Figures 1 to 3 A first limiting rod 7 is connected to the base 1, and the shorting rod is slidably connected to the first limiting rod 7. A sliding opening adapted to the first limiting rod 7 is opened on the shorting rod.

[0056] During specific implementation, this arrangement can limit and guide the sliding of the shorting rod and the paint spray head 203, further improving the stability of the shorting rod and the paint spray head 203 during the sliding process.

[0057] refer to Figure 2 A second limiting rod 10 is connected to one side of the driven rack 302 , and the second limiting rod 10 is slidably connected to the base 1 .

[0058] In specific implementation, this arrangement facilitates limiting and guiding the sliding of the driven rack 302 , further improving the stability of the driven rack 302 during the sliding process.

[0059] See Figure 3 Two mutually symmetrical fixing seats 11 are connected to the base 1 , and the driving plate 304 is slidably connected between the two fixing seats 11 .

[0060] In specific implementation, this arrangement facilitates installation of the driving plate 304 .

[0061] Working principle: The servo motor 202 starts and drives the adjustment shaft 201 to rotate in the base 1. When the adjustment shaft 201 rotates, due to the action of the slide, the paint head 203 will move away from or closer at equal intervals as the adjustment shaft 201 rotates to facilitate adaptation to cylinders of different lengths. In this way, the best painting effect can be achieved according to steel cylinders of different sizes. At the same time, multiple wiping heads 204 are provided on one side of the cylinder, and each wiping head 204 is located between two paint heads 203. When the position of the paint head 203 is adjusted, the synchronous adjustment component 300 in the base 1 will drive the wiping head 204 to adjust synchronously with the paint head 203. During the painting process, the paint head 203 sprays paint on the surface of the cylinder. Since the paint may be too thick at the junction between the two paint heads 203, the wiping head 204 located between the two paint heads 203 will play a role in wiping the thick paint, thereby ensuring the uniformity of the paint on the surface of the cylinder.

[0062] When the servo motor 202 drives the adjustment shaft 201 to rotate, the drive gear 301, which is coaxial with the adjustment shaft 201, also rotates. The rotation of the drive gear 301 drives the driven rack 302 engaged with it to move. The transmission frame 303 connected to the top of the driven rack 302 also moves accordingly.

[0063] The transmission frame 303 is connected to the top of the driving plate 304 which is vertically slidably connected to the base 1. The movement of the transmission frame 303 drives the driving plate 304 to slide vertically on the base 1. When the driving plate 304 slides vertically, the driven rod 307 is driven to slide in the sliding groove due to the inclined arrangement of the sliding groove, thereby causing the slider 306 to slide on the guide rod 305.

[0064] The slider 306 is connected to the spray head 203 and the wiping head 204. The sliding of the slider 306 causes the spray head 203 and the wiping head 204 to move synchronously. Thus, the coordinated action of the drive gear 301, the driven rack 302, the transmission frame 303, the drive plate 304, the guide rod 305, the slider 306, and the driven rod 307 enables synchronous adjustment of the spray head 203 and the wiping head 204.
