Atomization device for uniformly spraying surface of glass bottle

Abstract

The utility model relates to the technical field of spraying, in particular to an atomizing device for uniformly spraying the surface of a glass bottle. When the atomization device is used, firstly, a glass bottle to be sprayed is fixed to the center of the annular track through the clamp. The paint box is filled with paint, and under the action of the control system, the electric sliding block drives the paint box and the atomizing nozzle to move at a constant speed in the annular track. And the atomizing nozzle atomizes the coating and then uniformly sprays the coating on the surface of the fixed glass bottle, so that all-directional and dead-corner-free uniform spraying is realized. Due to the fact that the glass bottle is fixed, the problems of unstable speed, shaking, pause and the like in the rotating process are solved, the situation that sprayed paint flows or accumulates due to inertia is avoided, and the uniformity and stability of a coating are greatly improved. And the spraying operation is completed at a time, so that uneven spraying caused by repeated operation is avoided, and the production efficiency is remarkably improved. The method can be widely applied to the technical field of spraying.

Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and more specifically, to an atomizing device for uniformly spraying coating on the surface of glass bottles. Background Technology

[0002] After glass bottles are manufactured, a coating is often sprayed onto their surface to enhance them. Glass bottles are generally round and have a smooth surface, and existing spraying equipment is often fixed in position, only able to spray one side of the glass bottle.

[0003] Once one side is coated, rotating the glass bottle to spray other sides will result in uneven paint distribution. The main reasons are: firstly, the rotation speed is difficult to control precisely; too fast or too slow will affect the uniform adhesion of the paint; secondly, the rotation lacks stability, easily causing shaking or pauses, leading to the sprayed paint flowing or piling up due to inertia, resulting in inconsistent coating thickness—some areas with too much paint, while others have too little or even missed areas.

[0004] This uneven coating distribution greatly affects the appearance quality and performance of glass bottles. Therefore, it is urgent to develop an atomizing device that can achieve uniform spraying on the surface of glass bottles. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model proposes an atomizing device for uniform spraying on the surface of glass bottles.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] An atomizing device for uniformly spraying coating on the surface of glass bottles includes a coating tank and an atomizing nozzle, as well as a base plate, an annular track, an electric slider, and a control system. The annular track is set on the upper surface of the base plate, and the control system can control the electric slider to move within the annular track. The atomizing nozzle and the coating tank are fixedly connected to the electric slider, and a clamp for holding the glass bottle is provided at the center of the annular track.

[0008] When using this atomizing device, the glass bottle to be sprayed is first fixed at the center of a circular track using clamps. The paint tank contains paint, and under the control of the system, an electric slider drives the paint tank and atomizing nozzle to move at a constant speed within the circular track. The atomizing nozzle atomizes the paint and sprays it evenly onto the stationary glass bottle surface, achieving omnidirectional, dead-angle-free uniform spraying. Because the glass bottle is stationary, problems such as unstable speed, vibration, and pauses during rotation are eliminated, preventing the sprayed paint from flowing or piling up due to inertia, greatly improving the uniformity and stability of the coating. Furthermore, this spraying operation is completed in one pass, avoiding uneven spraying caused by repeated operations, significantly improving production efficiency.

[0009] Preferably, the clamp includes a clamping plate located directly above the center of the circular track, which can move up and down to clamp the glass bottle.

[0010] During the spraying operation on glass bottles, the clamping plate located directly above the center of the circular track can move up and down under the control of the system. When it is necessary to clamp the glass bottle, the clamping plate moves downward, cooperating with the circular track to clamp the glass bottle from both ends, securing it firmly in the center position. When spraying is complete and the glass bottle needs to be removed, the clamping plate moves upward to release the bottle. The design of the clamping plate, which can move up and down, can accommodate glass bottles of different heights, increasing the versatility and flexibility of the fixture.

[0011] As a preferred option, the base plate is also provided with an electric telescopic rod located outside the circular track, and a support rod is fixed on the side wall of the electric telescopic rod, with the clamping plate fixed on the support rod.

[0012] The electric telescopic rod enables precise control of the telescopic length, thereby ensuring accurate height adjustment of the clamping plate and meeting the clamping needs of glass bottles of different heights.

[0013] Preferably, the base plate has an installation groove located directly below the clamping plate, and a detachable limiting plate is provided in the installation groove. The upper surface of the limiting plate is flush with the upper surface of the base plate, and a limiting groove is provided on the upper surface of the limiting plate for the bottom of the glass bottle to be inserted.

[0014] First, select a matching limiting plate from a series of different sizes based on the diameter of the bottle bottom. Install the selected limiting plate into the mounting groove of the base plate. When the clamping plate lowers the glass bottle, the bottom of the bottle can be precisely engaged in the limiting groove of the selected limiting plate, thereby achieving precise and stable positioning of the glass bottle.

[0015] As a preferred embodiment, both the mounting groove and the limiting plate have circular cross-sections, the lower end face of the limiting plate is provided with a threaded post, and the bottom wall of the mounting groove is provided with a screw hole for the threaded post to be screwed in.

[0016] The threaded post and threaded hole work together to fix the limiting plate in the mounting groove, preventing the limiting plate from moving during use.

[0017] Preferably, the upper surface of the electric slider is provided with a set of first mounting holes, and also includes a movable plate and bolts. The movable plate is provided with multiple sets of second mounting holes. The bolts fix the movable plate to the electric slider through the first mounting holes and one of the second mounting holes. The paint box and the atomizing nozzle are fixed to the movable plate.

[0018] When spraying glass bottles, different sizes and materials require different distances between the atomizing nozzle and the bottle. If the distance is too far, the paint may over-spread before reaching the bottle surface, resulting in insufficient paint adhesion, a thinner coating, and affecting the coating quality and protective performance. If the distance is too close, the paint may accumulate in localized areas, causing uneven coating thickness or even sagging. Multiple sets of second mounting holes on a movable plate allow for adjustment of the position of the plate, thereby regulating the distance between the atomizing nozzle and the glass bottle to accommodate the spraying needs of glass bottles of different sizes and materials.

It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0026] Example

[0027] like Figures 1-4As shown, an atomizing device for uniformly spraying coating onto the surface of glass bottles is mainly composed of a base plate 120, an annular track 1301, an electric slider 1302, a control system, a coating tank 1101, an atomizing nozzle 1102, a clamp, an electric telescopic rod 1402, a limiting plate 150, and a moving plate 160. The annular track 1301 is located on the upper surface of the base plate 120, and the electric slider 1302 can move within the annular track 1301 under the control of the control system.

[0028] The paint tank 1101 and the atomizing nozzle 1102 are fixed to the movable plate 160 on the electric slider 1302. The clamp includes a vertically movable clamping plate 1401 located directly above the center of the annular track 1301, which is fixed to the support rod 1403 on the side wall of the electric telescopic rod 1402. The base plate 120 has a mounting groove 1201 located directly below the clamping plate 1401. A limiting plate 150 is installed in the mounting groove 1201 through a threaded post 1502 and a screw hole 1202. The upper end face of the limiting plate 150 has a limiting groove 1501 for the bottom of the glass bottle to be inserted.

[0029] The upper end face of the electric slider 1302 is provided with a set of first mounting holes 1303. In this example, the moving plate 160 is provided with three sets of second mounting holes 1602. The moving plate 160 and the electric slider 1302 are connected and fixed by bolts 1601.

[0030] The operating principle of the atomizing device in this embodiment is as follows:

[0031] In use, first select a suitable limiting plate 150 according to the size and shape of the bottom of the glass bottle to be sprayed, and install it in the mounting groove 1201 of the base plate 120. Place the glass bottle to be sprayed in the limiting groove 1501, and activate the electric telescopic rod 1402 to move the clamping plate 1401 downward, cooperating with the annular track 1301 to clamp the glass bottle. For glass bottles of different sizes and materials, adjust the distance between the atomizing nozzle 1102 and the glass bottle by selecting different second mounting holes 1602 on the moving plate 160 to achieve the best spraying effect.

[0032] After the adjustment is completed, the spraying operation begins. The paint in the paint tank 1101 is delivered to the atomizing nozzle 1102. At the same time, under the action of the control system, the electric slider 1302 drives the paint tank 1101 and the atomizing nozzle 1102 to move at a constant speed in the circular track 1301, atomizing the paint and spraying it evenly onto the surface of the stationary glass bottle.

[0033] During the spraying operation in this atomizing device, the glass bottle remains stationary while the electric slider 1302 drives the nozzle to rotate, which effectively prevents the paint already sprayed on the surface of the glass bottle from flowing or accumulating due to inertia; thus greatly improving the uniformity and stability of the coating and significantly improving the appearance quality and performance of the glass bottle.

[0034] The vertically movable clamping plate 1401 can accommodate glass bottles of different heights, increasing the versatility and flexibility of the clamp. The replaceable limiting plate 150 can be precisely positioned according to the size of the bottle bottom, ensuring the glass bottle is stable during spraying. The nozzle distance can be adjusted via multiple sets of second mounting holes 1602 on the moving plate 160 to accommodate glass bottles of different sizes and materials, avoiding excessive coating diffusion or accumulation and optimizing the spraying effect. This device completes uniform spraying in one pass, avoiding repetitive operations and significantly improving production efficiency.

[0035] In summary, the above are merely preferred embodiments of this embodiment. All equivalent changes and modifications made in accordance with the scope of the patent application of this embodiment shall fall within the scope of the patent of this embodiment.
