Description

Technical Field

[0001] The utility model belongs to the field of air tightness detection of plastic barrels, and particularly relates to an air tightness detection device for a plastic barrel. Background Art

[0002] Plastic barrels are mostly made of polyethylene, polypropylene and other plastics through blow molding and injection molding. They are mostly used for the storage and transportation of various liquids. They have good properties for special dangerous goods packaging. They are not easy to break, rust-proof and light in weight.

[0003] At present, the air tightness test of plastic barrels is one of the important indicators. Only by passing the air tightness test can the product be determined to be qualified. The air tightness test of plastic barrels is generally carried out by placing them below the water surface to observe whether there are bubbles overflowing to judge the sealing of the plastic barrel. This method is relatively cumbersome and there is a problem of misjudgment.

[0004] Therefore, in view of the shortcomings of the above scheme in actual production and implementation, it is revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model is created, and a plastic barrel airtightness detection device is provided to solve the above problems.

[0007] As a preferred embodiment of a plastic barrel airtightness detection device, a first cylinder is arranged on the outside of the push block, the output end of the first cylinder is fixedly matched with the push block, a slide groove is arranged at the bottom of the push block, a linear guide rail is arranged on the support plate corresponding to the push block, and the push block is slidably matched on the linear guide rail.

[0008] As a preferred embodiment of a plastic barrel air tightness detection device, the guide wheel assembly includes a guide wheel and a guide wheel frame, and a push block corresponds to the guide wheel, wherein one end of the push block is inclined.

[0009] With the above solution, since one end of the push block is inclined, when the push block moves along the linear guide rail, the guide wheel assembly will rise along the inclined end of the push block, thereby lifting the support platform to achieve adjustment of the height of the plastic barrel.

[0010] As a preferred embodiment of the airtightness detection device for a plastic barrel, telescopic columns are provided at four corners of the bottom of the support platform, and the support platform is fixedly matched with the support plate through the telescopic columns.

[0011] As a preferred implementation of a plastic barrel airtightness detection device, the telescopic column includes a guide column and a guide sleeve, and the guide column is slidably fitted in the guide sleeve.

[0012] By adopting the above solution, the guide column can be adaptively extended and retracted when the support platform is lifted, thereby achieving the stability of the support platform.

[0013] As a preferred embodiment of a plastic barrel airtightness detection device, the hollow reducer includes a hollow central shaft, and the hollow central shaft is equipped with a rotary joint for connecting an air pipe.

[0014] With the above solution, the hollow center axis will extend into the plastic barrel, and the gas transported by the air pipe will enter the plastic barrel, thereby generating a rated air pressure. If there is an airtight problem, the air pressure will decrease over time, and the change in air pressure can be used to determine whether there is a leak.

[0015] As a preferred implementation of a plastic barrel airtightness detection device, a third cylinder is provided on the top of the aluminum profile frame, and a top plate is provided at the output end of the third cylinder.

[0016] By adopting the above solution, the third cylinder presses the plastic barrel through the top plate, thereby preventing air leakage at the conveying end of the plastic barrel.

[0017] As a preferred embodiment of the airtightness detection device for a plastic barrel, a plastic barrel is provided between the top plate and the hollow reducer.

[0018] After adopting the above technical solution, the beneficial effect of the utility model is that the device has good operability to realize the airtightness detection of the plastic barrel.

[0019] Since one end of the push block is inclined, when the push block moves along the linear guide rail, the guide wheel assembly will rise along the inclined end of the push block, thereby lifting the support platform to achieve the adjustment of the height of the plastic barrel. The plastic barrel is fixed by the splint and the top plate, and the air tightness test is carried out through the air pipe connected to the hollow central axis to the plastic barrel, thereby generating a rated air pressure. If there is an airtight problem, the air pressure will decrease over time, so that the airtightness problem can be judged. BRIEF DESCRIPTION OF THE DRAWINGS
