Description

Technical Field

[0001] The invention relates to the technical field of industrial production, and in particular to an air duct for a plastic paint bucket stacking machine. Background Art

[0002] Currently, plastic paint buckets are widely used as containers for paint, slurry and wall paint.

[0003] Existing plastic paint buckets are mostly stacked manually when stacked and stored to avoid excess plastic paint buckets occupying processing space and to avoid the appearance damage caused by plastic paint buckets being stored separately. However, manual stacking of plastic paint buckets is inefficient, labor-intensive, and has a low degree of automation.

[0004] In addition, there are stacking devices specifically used for stacking barrels in the prior art, but this type of stacking equipment mostly uses mechanical rigid conveying and stacking machine transfer. This rigid contact method can easily damage the appearance of the plastic paint barrel, and the stacking efficiency still cannot meet the plastic paint barrel stacking requirements of paint processing companies.

[0005] Therefore, how to use a stacking device to avoid the rigid connection of the outer wall of the paint bucket and improve the stacking efficiency is a technical problem that needs to be solved urgently by technical personnel in this field.

[0008] After analysis, the stacking device in the above-mentioned patent disclosure has significant differences in structure and function from the present application, so it does not affect the novelty of the present application. Summary of the invention

[0009] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an air duct for a plastic paint bucket stacking machine. The air duct uses wind force to push the stacked plastic paint buckets, avoiding rigid clamping of the outer walls of the paint buckets. The stacking efficiency under the push of airflow is significantly better than that of the existing stacking machine with a mechanical transmission structure, and it is fully automated, effectively improving the stacking efficiency.

[0022] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings. It should be noted that the embodiments are illustrative, not restrictive, and the protection scope of the present invention cannot be limited thereby.

[0023] A duct for a plastic paint bucket stacking machine, one end of the duct is movably connected to a fan 1, the other end of the duct is axially provided with a feed port 12, the duct comprises a tube body 4 and a hollow bracket 5; the hollow bracket is a tubular structure and is coaxially fixed inside the tube body, one end of the hollow bracket is provided with a conical feed port 7, the other end of the hollow bracket is coaxially fixed with a ventilation baffle 2 fixed to the inner wall of the tube body; the hollow bracket is welded by a plurality of axially extending and circumferentially spaced square steel pipes 8, wherein the outer wall of the hollow bracket and the inner wall of the duct together form an outer air duct 3, the outer walls of the plurality of square steel pipes form a columnar stacking area 11, and the inner walls of the plurality of square steel pipes connected to the feed port and the fan form an inner air duct 9.

[0024] Moreover, the stacking area is connected to the external air duct through the gaps between the plurality of square steel pipes.

[0025] Moreover, a plurality of radial fixing plates 6 are radially fixedly mounted on the outer periphery of the hollow bracket, and the other end of the radial fixing plate is fixedly connected to the inner wall of the air duct.

[0026] Moreover, a plurality of ventilation holes are formed on the ventilation baffle, and a piston hole 13 for ejecting the plastic paint bucket is formed in the middle of the ventilation baffle.

[0027] In addition, the present invention preferably adopts a mature product in the prior art for stacking plastic paint buckets, and a plurality of air ducts are rotatably supported inside the stacking machine, wherein the air ducts in the stacking feeding state are connected to the air fan, and the air ducts in the stacking discharging state are rotated and adjusted to the discharging position, and the cylinder piston rod axially penetrates the piston hole in the middle of the ventilation baffle to axially eject the stacked plastic paint buckets inside the hollow bracket, wherein the fan and the cylinder are both mature products in the prior art, and the rotationally adjustable connecting air ducts in the stacking machine and the connection method of the fixed cylinder on the stacking machine are both mature technical means in the prior art.

[0028] To more clearly illustrate the specific implementation of the present invention, an example is provided below:

[0029] The air duct for a plastic paint bucket stacking machine of the present invention has an air flow direction as follows: Figure 4 As shown, the fan draws air from the air duct, forming a negative pressure inside the air duct. At this time, the plastic paint bucket inside the hollow bracket will be pushed by the airflow to perform an axial sliding action, and at this time, the airflow pushes the plastic paint bucket axially inside the stacking area, and the excess airflow flows from the gaps between multiple square steel pipes to the external air duct and finally flows to the fan. The high-speed airflow in the external air duct forms airflow protection for the circumferential outer wall of the plastic paint bucket to avoid excessive sliding friction between the circumferential outer wall of the plastic paint bucket and the inner wall of the hollow bracket. Finally, the inner air duct inside the square steel pipe is used to prevent airflow blockage and thus shorten the service life of the fan.

[0030] Finally, all the parts not described in the present invention adopt mature products and mature technical means in the prior art.

[0031] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
