Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning round tube products, in particular to a pneumatic cleaning device for round tube products. Background Art

[0002] The automotive nozzles and hoses currently produced are short, numerous, and have high cleanliness requirements. They must be cleaned through multiple steps to achieve the required cleanliness requirements. The final cleaning method of the product is to use a manual handheld air gun to clean the outer surface and inner hole of the product. This type of manual cleaning method is inefficient, and the cleaning action is not standardized, full of uncertainties, and is likely to lead to the outflow of defective products.

[0003] In the prior art, the air cleaning device used for products such as cables and shafts uses a cleaning method in which the entire long product passes through a fixed cleaning device in a single direction, and air is used to form a wind blade to clean the surface of the product. However, this cleaning method still has the following defects:

[0004] 1. The cleaning method is single. Since the cleaning device is fixed and cannot move, the parts need to pass through the middle hole directly, which is only conducive to cleaning the surface of a single product;

[0005] 2. When faced with a large number of short and hollow round tube products, it can only clean the surface, and cannot work continuously due to product clamping reasons. Utility Model Content

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a pneumatic cleaning device for round tube products, which solves the problems of irregular cleaning and low cleaning efficiency of short and large round tube products in the prior art.

[0007] To achieve the above-mentioned objectives, according to an embodiment of the first aspect of the utility model, a pneumatic cleaning device for round tube products is proposed, comprising an L-shaped base and a T-shaped slider slidably mounted on the vertical part of the L-shaped base, the bottom of one end of the T-shaped slider is connected to an annular air blade through symmetrically arranged hanging ears, the annular air blade comprises an upper part of the air blade, a lower part of the air blade, an annular air chamber and a tapered air outlet, an annular air chamber is formed between the upper part of the air blade and the lower part of the air blade, the tapered air outlet is connected to the bottom of the annular air chamber, an inner hole cleaning air pipe is also installed on the T-shaped slider, the inner hole cleaning air pipe extends into the annular air blade, and the inner hole cleaning air pipe is provided with evenly distributed cleaning holes on the tube wall near the bottom end, the vertical part of the L-shaped base is installed with a cylinder for driving the T-shaped slider to rise and fall, and the horizontal part of the L-shaped base is provided with a product placement port located directly below the annular air blade.

[0008] As a further technical solution of the utility model, air inlets are symmetrically arranged on both sides of the upper portion of the air blade, and an inverted U-shaped tube is connected between the two air inlets, and a first air inlet hose is connected to the inverted U-shaped tube.

[0009] As a further technical solution of the utility model, the top end of the inner hole cleaning air pipe is connected to a second air intake hose.

[0010] As a further technical solution of the utility model, a one-way conveyor belt is provided below the annular air blade, and a plurality of evenly distributed product placement openings are provided on the one-way conveyor belt.

[0011] As a further technical solution of the utility model, a gap is provided between the bottom end of the upper part of the air blade and the bottom end of the lower part of the air blade, and the gap is a tapered air outlet.

[0012] As a further technical solution of the present invention, the cross-section of the gap is an isosceles trapezoidal structure, and the spacing of the gap is 0.02 mm.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, gas is input on both sides of the annular air blade, and the gas is pressurized in the annular air chamber and then transferred to the tapered air outlet, so as to blow out a 360-degree wind blade and clean the outer surface of the product without dead angles, which is more comprehensive and standardized than manually holding an air gun in one hand and blowing air on the product in the other hand.

[0015] 2. In the utility model, by adding an inner hole cleaning air pipe, when the annular air blade cleans the outer surface of the product, the gas is introduced through the inner hole cleaning air pipe and blown out through the evenly distributed cleaning holes, thereby facilitating the cleaning of the inner wall of the product and meeting the cleaning requirements of the inner hole and inner wall of the product.

[0016] 3. In the utility model, the lifting of the T-shaped slider is conveniently controlled by starting the cylinder. The T-shaped slider drives the annular air blade and the inner hole cleaning air pipe to move synchronously. The product cleaning can be completed by reciprocating up and down once. A cleaning cycle can be adjusted to 2-3 seconds, which is 2-3S faster than pure manual cleaning. It can solve the problem of low cleaning efficiency due to short products and large quantities.

[0017] 4. In the utility model, the one-way conveyor belt is used to facilitate the transportation of the cleaning products. Workers put the products on one end, and the products are conveniently transported to the bottom of the annular air blade and the inner hole cleaning air pipe through the one-way conveyor belt. After cleaning, they can continue to be transported to the other end of the one-way conveyor belt. After the cleaned products reach the edge, they can fall into the finished product storage box by gravity. In this form, workers only need to put the products on the one-way conveyor belt, which reduces the steps of taking products, ensures the cleaning rate and is conducive to improving work efficiency.
